Description

[Detailed description of the invention] This invention relates to a water remover that collects rainwater, etc. that remains in grounds and the like.

When removing rainwater that remains on grounds etc., a method of absorbing water using a piece of sponge or a rag requires a lot of time and effort, for example.

Therefore, in the past, for example,
As shown in the above publication, a cylindrical body with a large number of through holes is rotatably supported on a frame, and a water absorbing body made of sponge is wound around the outer periphery of the cylindrical body. A water remover has been developed in which a roller that presses the body and a water receiving tank disposed inside the cylindrical body are assembled.

However, according to the water remover having the above structure, since the water absorption drum made up of the cylindrical body and the water absorption body rotates while directly resting on the ground, the water absorption body is not only severely damaged; It is difficult to run smoothly and it is extremely difficult to turn, and if you try to turn forcibly, the water absorbing body wound around the outer circumference of the cylinder may break or the cylinder may shift to one side. There is a problem with this.

This invention was developed in view of the above circumstances.
The purpose is to provide a water removal machine that has excellent water removal effects, can run smoothly, and can turn easily.

Therefore, in the present invention, a cylindrical body having a large number of through holes formed by winding a water absorbing material such as a sponge around its outer periphery is supported in a frame so as to be rotatable, and a roller that presses the sponge against the frame and a roller inside the cylindrical body are provided. In a water remover assembled with a water tank placed in the
A water passage hole penetrating from the outer circumferential surface to the inner circumferential surface of the sponge is formed in the sponge, and a water hole is formed on both sides of the cylindrical body in the frame with a diameter slightly larger than the outer diameter of the water absorbent body wound around the cylindrical body. A pair of small-diameter wheels is rotatably supported coaxially with the cylindrical body, and the cylindrical body is fixed to one of the wheels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A water remover according to the present invention will be explained below with reference to embodiments shown in the drawings.

In the figure, 1 is a U-shaped frame, and between the open end of the frame 1, a pair of wheels 2,
2 are supported to be rotatable independently, and a connecting shaft 3 is connected between the axles 2a and 2b of the wheels 2, 2.
has been established.

A large number of small holes 4a are provided in the middle part of the wheels 2, 2.
A cylindrical body 4 having a diameter slightly smaller than that of the wheels 2, 2 formed with
is supported concentrically with the wheels 2, 2, and
A water absorbent body 5 made of sponge is placed around the outer periphery of this cylindrical body 4.
It is wrapped in

That is, the water-absorbing body 5 of the water-absorbing drum D is wound so that its outer peripheral surface slightly bulges outward in the radial direction from the outer diameter of the wheels 2, 2, and in this way, the water-absorbing body 5 is grounded. Accordingly, after the ground contact part of the water absorbent body 5 is compressed, when this compressed part separates from the ground, that is, when the water absorbent body 5 is released from the compressed state and expands, it absorbs water on the ground. This is how it is done.

A water tank 6 having an opening 6a at its upper portion is supported within the cylindrical body 4 via the connecting shaft 3.

The upper part of the water tank 6 near the opening 6a side is freely inserted and supported by the connecting shaft 3, and the opening 6a is always oriented upward due to the weight of the water tank 6, and the bottom part is directed downward. When the water absorbing body 5 is squeezed by a squeezing roller to be described later,
The water squeezed out from the water absorbing body 5 is received and stored in the water receiving tank 6.

Further, on the frame 1, a U-shaped support frame 7 is freely pivoted via a shaft 8, and a grounding portion 7a is formed at one end of the arm 7 centered on the pivot shaft 8. , and the squeeze roller 9 is supported on the open side of the other end, and a tension spring 10 is interposed between the grounding portion 7a side of the arm 7 and the frame 1, so that the squeeze roller 9 is supported by the water absorption side. It is pressed against the outer peripheral surface of the body 5 in order to squeeze out the water absorbed by the water absorbent body 5.

A stopper rod 11 is attached to the frame 1, and the stopper rod 11 closes the squeeze roller 9.
can be held in a non-contact position with respect to the water absorbent body 5.

A plurality of water passage holes 12 are formed in the water absorbent body 5, penetrating from the outer circumferential surface to the inner circumferential surface of the water absorbent body 5. By doing so, for example, when a large amount of water is absorbed into the water absorbent body 5, When the water is squeezed by the squeezing roller 9, the absorbed water is allowed to quickly fall and drain into the water receiving tank 6 through the water passage hole 12 without overflowing from the outer periphery of the water absorbing body 5.

The water passage hole 12 may be a circular hole or a long hole extending in the axial direction of the water absorbing body 5. When the axial length of the water absorbing body 5 is approximately 500 mm, the circular hole is approximately 20 mm long.
mm, and the elongated hole is preferably approximately 20 mm x 50 mm.

In the illustrated embodiment, the cylindrical body 4 that wraps around and supports the water absorbent body 5 is supported as follows: a boss portion 13a, a plurality of support rods 13b extending radially from the boss portion 13a, and a plurality of support rods 13b. Using a support member 13 consisting of a cylindrical body 13c supported via a support rod 13b, the boss portion 13a of the support member 13 is fitted and supported on the left end of the connection shaft 3 so as to be freely rotatable. The cylindrical body 13c of the support member 13 fixedly supports one side of the cylindrical body 4 in the axial direction, and the rim 2a of the right wheel 2 located on the opposite side to the support member 13 has a cylindrical shape integrally with the rim 2a. A body 14 is attached, and the other axial side of the cylindrical body 4 is fixedly supported by the cylindrical body 14.

By integrally supporting the cylindrical body 4, that is, the water absorbing body 5, on the right wheel 2 in this manner, the wheel 2
A rotational force is applied to the water absorbing body 5 through the water absorbing body 5 to perform a water absorption action on the entire circumferential surface of the water absorbing body 5. Also, a rotational force is applied to the water absorbing body 5 only from the right wheel 2, while the left wheel 2 is held so that it can rotate independently relative to the water absorbing body 5, so that when turning, for example, the left wheel 2 can be turned as the center,
This makes it easier to perform this turning operation.

In addition, in the illustrated embodiment, in order to attach the water absorbent body 5 to the outer periphery of the cylindrical body 4, as shown in detail in FIG. The tape 15 is wound around both sides of the water absorbent body 5 in the axial direction to compress the water absorbent body 5, and the water absorbent body 5 is integrally attached to the cylinder body 4. A cover 16 is wound around the outer circumference of the water absorbent body 5 to perform a filtration action, such as a non-woven fabric to protect the water absorbent body 5, and both ends of the cover 16 in the width direction are held on the water absorbent body 5 by the tapes 15. In the unlikely event that the cover 16 is damaged, it can be easily replaced by peeling it off from the tape 15.

In the figure, reference numeral 17 denotes a drainage hole provided at the bottom of the water tank 6, and a stopper 18 is removably attached to the drainage hole 17.

In addition, in the embodiment shown in the figure, as shown in FIG. 5, a tape 21 having a large number of engagement protrusions similar to the tape 15 is provided at one end of the water absorbent body 5 in the length direction, and a tape 21 is provided at the other end in the longitudinal direction. A tape 22 having a loop-shaped engagement portion that engages with the engagement protrusion is provided, and when the water absorbent body 5 is wrapped around the cylinder body 4, both ends thereof are connected via the tapes 21 and 22. At the same time, a portion of the engagement protrusion of the tape 21 is exposed, and the winding start end of the cover 16 is attached to this exposed surface.

Further, a tape 23 having a large number of engaging protrusions is also provided at the end of the winding of the cover 16.

The water remover of the present invention is constructed as described above.
When performing water removal work on grounds etc., lift the frame 1 as shown in Fig. 2.
The grounding portion 7a of the support arm 7 is separated from the ground, and the engagement of the squeezing roller 9 by the stopper rod 11 is released, and the roller 9 is moved by the spring 10.
It is pressed against the outer surface of the water absorbent body 5.

After preparing in this manner, the frame 1 is held and each wheel 2 is rotated, and the cylinder 4 around which the water absorbing body 5 is wound and the water receiving tank 6 are held by the two wheels 2, 2. Since the load is not directly applied to the cylinder 4, in other words, the cylinder 4 does not rest directly on the ground, so the water absorbent body wound around the cylinder 4 5 is less likely to get damaged.

As the wheel 2 rotates, the cylindrical body 4 fixed to the right wheel 2 also rotates reliably, and the entire circumferential surface of the water absorbing body 5 wound around the cylindrical body 4 sequentially touches the ground surface. When the water absorbent body 5 contacts the ground and absorbs water, that is, when the water absorbent body 5 touches the ground and separates, that is, when the water absorbent body 5 is compressed and swells, the water accumulated in the gland filtered by the cover 16 is removed. Water is absorbed by the water absorbent body 5, and when the water absorbing portion of the water absorbent body 5 reaches the squeezing roller 9, the water absorbed by the water absorbent body 5 is squeezed out by the roller 9, and this water is It flows down into the water receiving tank 6 from the small hole 4a of the cylindrical body 4 and is stored in the water receiving tank 6.

Furthermore, if there is a large amount of water accumulated in the ground and a large amount of water is absorbed by the water absorbing body 5, when the water absorbing body 5 is squeezed by the squeezing roller 9, it may overflow from the outer periphery of the water absorbing body 5 and fall onto the ground. The water absorbed by the water absorbing body 5 quickly falls and is discharged into the water receiving tank 6 from the water passage hole 12 provided in the water absorbing body 5.

In order to turn the water remover, for example, the left wheel 2 may be turned as the turning center, and the left wheel 2 may be independent of the right wheel 2 to which the cylinder 4 is fixed. Since it rotates, it can turn smoothly while the water absorbing body 5 absorbs water.

After the water removal work as described above is completed, as shown in FIG.
is held in a non-contact position with respect to the water absorbent body 5, and the grounding portion 7a of the arm 7 is grounded to hold the frame 1 horizontally.

As described above, in the present invention, a cylinder having a large number of through holes formed by winding a water absorbing material such as a sponge around its outer periphery is rotatably supported on a frame, and a roller that presses the sponge against the frame and a cylinder inside the cylinder. In a water remover assembled with a water tank placed in the
A water passage hole is formed in the water absorbent body passing through from the outer circumferential surface to the inner circumferential surface of the water absorbent body, and a water hole is formed on both sides of the cylindrical body in the frame from the outer diameter of the water absorbent body wound around the cylindrical body. By supporting a pair of small-diameter wheels coaxially with the cylindrical body so as to freely rotate, and fixing the cylindrical body to one of the wheels, the cylindrical body around which the water absorbing body is wound and the receiving body are fixed. Since the water tank is held by the two wheels, no load is directly applied to the cylindrical body, or in other words, the cylindrical body does not rest directly on the ground and rotate. The water absorbing body is not easily damaged, and when the wheel rotates, the cylindrical body also forcibly rotates to ensure water removal from the ground. For example, if the wheel to which the cylindrical body is not fixed is rotated around the center of rotation, the wheel rotates independently of the wheel to which the cylindrical body is fixed, so that the water absorption work by the water absorbing body can be carried out reliably. This allows you to turn smoothly.

In addition, according to the present invention, since water passage holes are formed in the water absorbing body, even if there is a large amount of water accumulated in the gland etc. and a large amount of water is absorbed by the water absorbing body, this water can be squeezed out by the squeezing roller. At times, the water can be quickly discharged from the water passage hole to the water receiving tank without overflowing from the outer periphery of the roller and falling onto the ground, and the water removal efficiency can be significantly improved. It is.

In summary, according to the present invention, the water removal effect is excellent, and the vehicle can run smoothly and turn easily.
