Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a water removing device, and more particularly to a water removing device for removing water accumulated on a coat, a road surface, and the like.

[Prior Art] As a water removing apparatus of this type, there is one conventionally described, for example, below.

There are several different types of tennis courts currently used, including Lone, Antuca, Clay and Hard. Depending on the type and equipment of this coat, there are some that cannot be used when it rains, and the hard coat can be used by removing the rainwater on the coat if the rain is stopped.

There are two ways to remove the rainwater that has accumulated on the hard coat: broom it or push it with a rubber spatula to discharge it out of the court. I'm doing it.

[Problems to be Solved by the Invention] All of the above-mentioned conventional methods require a great deal of effort to remove rainwater on a rectangular coat (about 261 m ² ) surrounded by side lines and a baseline, and Even if it is carried out by a large number of people, it is not quite effective.

There is a problem that it is very inefficient to draw rainwater out of the court with a broom and it is extremely inefficient, and the method of pushing it out with a rubber spatula is low in efficiency in spite of using time and physical strength.

In order to eliminate the above-mentioned problems, the present invention interlocks with collecting rainwater on a coat by a large number of divided sponge-like water absorbing members and then squeezing it into a water receiving tank, and The purpose is to remove rainwater on the court quickly and efficiently by making it continuous.

[Means for Solving the Problems] The above-mentioned object of the present invention is to pivotally mount a rotating roller and casters on both sides in the length direction of a frame-shaped base, and to plant a pair of columns on the base. A guide roller is pivotally supported on the upper part of each of the support columns, and a diaphragm roller is pivotally supported between the guide rollers through a support piece having an inverted T shape or the like to guide the guide roller, the diaphragm roller and the rotation. An endless water-passing belt in which a plurality of water-absorbing members are attached to the outer surface of each roller is rotatably stretched so that the upper portion of the water-passing belt is substantially M-shaped.
Further, it is achieved by arranging a water receiving tank between the pillars below the squeezing roller and projecting a handle on the pillar or the base.

Further, the drainage pipe may be led out from the water receiving tank and connected to the sub water tank placed on the base.

Further, a sub-roller for inclining and guiding the ground contact portion of the water passage belt may be pivotally supported at an intermediate portion of the base.

Wheels may be pivoted on both sides of the rotating roller.

Further, a pressing roller may be pivotally supported below the squeezing roller.

Further, a transmission belt may be stretched between the squeezing roller or the pressing roller and the rotating roller.

[Operation] When a handle is pushed or pulled on a water-removed place such as a tennis court with a water pool, the water-passing belt becomes a caterpillar type through a number of water-absorbing members, a rotating roller, a guide roller and a squeezing roller. Rotate.

Since a large number of water absorbing members rotate while contacting the surface to be removed with the rotation of the belt, the water in the water pool is sucked into the water absorbing members one after another by the expansion force generated after decompression of each water absorbing member. Can be made.

After that, each suction member can be compressed one after another by the squeezing roller that is pivotally supported in the valley of the water-passing belt that is hung over the upper part of the strut, and the water absorbed by each suction member is squeezed out one after another. It is possible to naturally flow down into the water receiving tank through a large number of holes of the water passage belt to store water, and by draining the stored water to another place, water to be removed can be removed.

Since the squeezing roller is provided in the trough of the M-shaped bridge at the upper part of the water passage belt, the squeezed water flows down into the water receiving tank directly below.

In addition, since the casters support one side of the base, the direction can be easily changed.

Particularly, since the water absorbing member in this invention is divided into a plurality of parts and attached to the outer surface of one endless water-passing belt, the water absorbing members at the bridging portion of each roller have their outer sides radially separated from each other. As a result of passing through the transfer section, the water absorbing member is not compressed / expanded due to the difference between the inner circumference and the outer circumference, so that a smooth and light turning action is exhibited.

And a large number of water absorbing members accompanying the rotation of the water passing belt 9
Since 8 and 8 rotate while compressing and contacting the surface to be removed, it is possible to cause each water absorbing member to absorb water in the water pool one after another by the expansion force generated after decompression of each water absorbing member 8 and 8. .

After that, the water absorbing members 8 can be compressed one after another by the squeezing rollers 7 pivotally supported in the valleys of the water passing belts 9 hung over the upper portions of the columns 4 in a substantially M shape, and the water absorbing members 8 absorb water. Water is squeezed out one after another, and a large number of drain holes 9b of the water passage belt 9 are formed.
After that, the water can be naturally flowed down to the water receiving tank 10 to temporarily store the water, and the water to be removed E can be removed by draining the stored water to another place with a rubber hose or the like.

Since the squeezing roller 7 is provided in the M-shaped bridging valley above the water passage belt 9, the squeezed water flows down into the water receiving tank 10 directly below.

Also, since the Custa 3 supports one side of the base 1, the direction can be changed easily.

In particular, since the water absorbing member 8 in this invention is divided into a large number and attached to the outer surface of one endless water-passing belt 9, the outer sides of each water absorbing member 8 in the spanning portion of each roller are radially separated from each other. On the other hand, as a result of passing through the bridging portion, the water absorbing member 8 is not compressed / expanded due to the difference between the inner circumference and the outer circumference, so that a smooth and light turning action is exhibited.

That is, by moving this device in the coat in the direction shown by the arrow in FIG. 1, the rotating roller 2 and the caster 3 rotate, and the water absorbing member 8 travels on the guide rollers 5, 5 via the water passing belt 9. As shown in FIGS. 1 and 2, the rotating roller 2 absorbs rainwater on the coat surface by the water-absorbing member 8 which runs in parallel while being pressed against the coat surface, and the absorbed water-absorbing member 8 is compressed by the guide roller 7. The rainwater absorbed and squeezed out is squeezed out into the water receiving tank 10 through the drainage hole 9b of the belt, and the water absorbing member 8 that has recovered the water absorbing power is fed out. Rainwater on the surface is a water tank 10
Will be recovered in.

It rotates in a caterpillar manner via a rotary roller 2, a guide roller 5 and a diaphragm roller 7.

Then, along with the rotation of the water passage belt 9, a large number of water absorbing members 8
Rotates while coming into contact with the surface E to be removed, each water absorbing member
The water in the water pool can be successively absorbed by each water absorbing member by the expansion force generated after the decompression of 8 and 8.

After that, the water absorbing members 8 can be compressed one after another by the squeezing rollers 7 pivotally supported in the valleys of the water passing belts 9 hung over the upper portions of the columns 4 in a substantially M shape, and the water absorbing members 8 absorb water. Water is squeezed out one after another, and a large number of drain holes 9b of the water passage belt 9 are formed.
After that, it can be naturally flowed down to the water receiving tank 10 to store water,
By draining this stored water to another place, the water to be removed E
Can be drained.

Since the squeezing roller 7 is provided in the valley of the M-shaped bridging at the upper part of the water passage belt 9, the squeezed water flows down into the water receiving tank 10 directly below, so that it does not spill to the side.

In addition, the casters 3 support one side of the base, so that the direction can be easily changed.

In particular, since the water absorbing member 8 in this invention is divided into a large number and attached to the outer surface of one endless water-passing belt 9, the outer sides of each water absorbing member 8 in the spanning portion of each roller are radially separated from each other. On the other hand, as a result of passing through the bridging portion, the water absorbing member 8 is not compressed / expanded due to the difference between the inner circumference and the outer circumference, so that a smooth and light turning action is exhibited.

Therefore, according to the present invention, it is possible to remove rainwater accumulated on a place to be water-removed, for example, a tennis court, in a short time by one person, and there is an effect that a large amount of labor is not required for removing water.

According to the second aspect, the amount of stored water can be increased and the number of drains can be reduced, which is convenient.

In the third aspect, the water absorbing member does not swell suddenly, so that the water absorbing action is slightly improved.

According to claim 4, since there is a pair of wheels, the amount of compression when the water absorbing member is in contact with the ground can be made constant regardless of the amount of stored water, and the water absorbing ability can be made constant, so that the service life of the water absorbing member can be extended. Moreover, if one of the wheels is made to rotate freely, the direction can be changed more easily.
