Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a water removal device, and more specifically, to a water removal device that simply and easily removes large amounts of water accumulated on courts, road surfaces, etc. in a hand-operated manner. Regarding water equipment.

[Prior Art] This type of water removal device is conventionally known, for example, as described below.

There are several different types of tennis courts currently in use: lawn, antuca, clay, and hard.

Depending on the type and equipment of this court, some courts cannot be used when it rains, while hard courts can be used once the rain stops by removing the rainwater on the court.

Currently, there are two ways to remove rainwater that has accumulated on the hard court: using a float or pushing it with a rubber spatula to drain it out of the court, and a palliative method is to soak a rag with rainwater and squeeze it into a bucket. That's how I do it.

[Problems to be Solved by the Invention] In all of the above-mentioned conventional methods, removing rainwater from a rectangular court (approximately 261 ffl) surrounded by the side line and the baseline requires a great deal of effort and requires a lot of effort. Even if it is carried out by a large number of people, it cannot be done effectively.

Pushing rainwater out of the court with a paddle is like scooping up rainwater in a colander, which is extremely inefficient, and the method of pushing the rainwater with bombs and the like also has the problem of being inefficient considering the amount of time and physical strength it uses.

In order to eliminate each of the above-mentioned problems, this invention has a system in which rainwater on the court is absorbed by a sponge-like water-absorbing member divided into many parts, and then collected in a water-receiving tank by squeezing it and continuously. The purpose is to quickly and efficiently remove rainwater from the court by having the player perform this process.

[Means for Solving the Problems] The above-mentioned object of the present invention is to provide a pair of water absorbing members in configuring a device that removes water by bringing a water absorbing member into contact with a surface to be water removed and causing the water absorbing member to absorb accumulated water. A large number of rotating rollers are provided around the steel plate except for the upper and lower parts thereof, and a suppression roller is provided at the lower part of the side plate, each pivotally supported between the side plates, and between the two uppermost rotating rollers of each of these rotating rollers. An endless water-passing belt which pivotally supports a squeezing roller and has a multi-divided water absorbing member attached to the outer surface of the lower surface of the squeezing roller and the outer surface of each of the rotating rollers and the pressing roller is provided so that the upper part thereof is flat. A space surrounded by a body plate and each side plate, which are arranged so as to be rotatable and extended and arranged liquid-tight between each side plate along the inside of the many rotating rollers, is used as a water tank. None, furthermore, a drain valve is provided at the lower part of the side plate, a handle is provided protruding from each side plate, and a presser roller is pivotally supported with a water absorbing member sandwiched between the lower part of the squeezing roller, and the presser roller and the pressing roller This is achieved by passing a belt between the

Further, the rotating roller, the pressing roller, the pressing roller, and the water belt may each be divided and arranged in two rows.

[Function] When the handle is moved by pushing or pulling on a place where water is to be removed, such as a tennis court where there is a puddle, the water conveying belt passes through a rotating roller, a pressing roller, and a squeezing roller along with a large number of water absorbing members, and then moves in a caterpillar style. Rotate to.

As the belt rotates, a large number of water absorbing members rotate while coming into contact with the surface to be water removed, so the expansion force generated after the compression roller of the lower water absorbing member is released causes water to accumulate in each water absorbing member. water can be absorbed one after another.

After that, each water-absorbing member can be compressed one after another by a squeezing roller and a pressing roller pivoted between the water-passing belt that is stretched almost flat at the top of the water tank, and the water absorbed by each water-absorbing member is The water can be squeezed out one after another and allowed to naturally flow down into the water tank through the many holes in the water belt and stored. By draining this stored water elsewhere, it is possible to remove water from the area to be removed. .

Since there is a squeezing roller and a pressing roller in the middle of the water conveying belt, which extends flatly over the upper part of the belt, the squeezed water flows down into the water receiving tank directly below.

Further, if the rotating roller, squeezing roller, pressing roller, pressing roller, and water belt are each divided into two rows and rotated individually for each row, the direction can be changed easily.

In particular, the water-absorbing member in this invention is divided into many parts and attached to the outer surface of one endless water-passing belt. As a result, the water-absorbing member rotates through the transfer portion, and since the water-absorbing member is not compressed or expanded due to the difference between the inner and outer circumferences, it exhibits a smooth and light caterpillar-type rotational movement.

In each figure, the reference numeral 6a indicates a water guide provided on the upper part of the body plate 6, and the reference 9a indicates a reinforcing stay 1.
Reference numeral 2 indicates a drainage hole of the water belt 5, and E indicates a location from which water is to be removed.

Also, what is indicated by the reference numeral 14 in FIGS. 1 and 4 is a roller that prevents the entire device from leaning forward during use. If this is done, the entire device will not lean forward even if the roller 14 mentioned above is omitted.

The water removal device of the present invention is constructed as described above, and the basic operation of this device will be explained below.

When the handle 9 is moved in the direction of the arrow in FIG. 1 by pressing the handle 9 on a place E to be water removed such as a tennis court where there is a puddle, the water belt 5 moves along with a large number of water absorbing members 4.4 to the rotating roller 2.2, Press roller 2a1 press roller 10 and squeeze roller 3
After that, it rotates in a caterpillar style in the direction of the arrow in Figure 1.

As the water belt 5 rotates, the lower one of the many water absorbing members 4.4 rotates while being compressed and in contact with the water removal surface, so that the water absorbing members 4, 4 at the lower part are pressed. The expansion force generated after the compression is released by the rollers 2a allows each water absorbing member to absorb water from the puddle one after another.

Thereafter, each water absorbing member 4.4 can be compressed one after another by a squeezing roller 3 and a pressing roller 10, which are pivotally supported in the middle of a water belt 5 that is stretched almost flat over the upper part of the water receiving tank 7. The water absorbed by the water absorbing member 4.4 can be squeezed out one after another and allowed to naturally flow down into the water receiving tank 7 through the many drainage holes 12 of the water belt 5, so that the water can be temporarily stored. Water can be removed from the location E by draining water to another location using a drain valve 8 such as a rubber hose or a faucet cock.

The squeezing roller 3 and the pressing roller 10 are located in the middle of the water conveying belt 5, which is stretched across the upper part of the water conveying belt 5.
The squeezed water flows down into the water receiving tank 7 directly below.

In addition, the rotating rollers 2, 2 and the water belt 5 are connected to the second
As shown in the figure and FIG. 5, the direction can be easily changed by arranging them in two rows and rotating each row individually.

In particular, since the water absorbing members 4, 4 in this invention are divided into many parts and attached to the outer surface of one endless water belt 5,
Each of the water absorbing members 4.4 at the spanning portion of each roller passes through the spanning portion while their outer sides radially move away from each other, and the water absorbing members 4 are not compressed or expanded due to the difference between the inner and outer circumferences. Therefore, it can rotate smoothly and easily.

In other words, by moving this device in the direction of the arrow in FIG. . The rainwater compressed and absorbed between the holding roller 10 and the water-absorbing member 4 is squeezed out into the water receiving tank 7 through the drainage hole 12 of the water belt, and the water-absorbing member 4 which has recovered its water-absorbing power is fed out. By moving the device back and forth over the surface E to be water removed, rainwater on the court surface is collected into the water receiving tank 7.

The water W collected in the water receiving tank 7 is drained into a drain or the like through a drain valve 8 provided as shown in FIGS. 2 and 4.

Since the water absorbing member 4 is in pressure contact with the surface E of the area to be water removed, it should be replaced when it wears out or when its water absorbing function deteriorates.

When replacing this, each roller 2. 2a, 310 can be freely replaced by removing them from the pivot 2b, and after use, they can be washed with water by hanging them between the removed rollers to remove moisture and drying.

In addition, as shown by the chain line in FIG. 1 and FIG. 4, handles 9 may be provided at the front and back to move the device forward or backward.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

In the water removal device according to claim 1, when the handle 9 is moved by pushing or pulling on a place E to be water removed such as a tennis court where there is a puddle, the water passage belt 5 moves a large number of water absorbing members 4.
．． 4 together with a rotating roller 2, a pressing roller 2as, a pressing roller 10, and a squeezing roller 3, and rotate in a caterpillar manner.

As the water belt 5 rotates, the lower one of the many water absorbing members 4, 4 rotates while being in contact with the surface E to be water removed, so that expansion occurs after the lower water absorbing member 44 is released from compression. It is possible to force each water absorbing member to absorb water from a puddle one after another.

Thereafter, each water absorbing member 4.4 can be compressed one after another by a squeezing roller 3 and a pressing roller 10, which are pivotally supported in the middle of a water belt 5 that is stretched almost flat over the upper part of the water receiving tank 7. The water absorbed by the water absorbing member 4 can be squeezed out one after another and allowed to naturally flow down to the water receiving tank 7 through the water belt 5 (numerous drainage holes 12) and stored.
Water can be removed from the location E by draining the water to another location.

Since there is a squeezing roller 3 and a pressing roller 10 in the middle of the upper part of the water belt 5, which extends almost flatly, the squeezed water flows down into the water receiving tank 7 directly below, so it spills to the side. Never.

In particular, the water absorbing member 4 in this invention is divided into a large number of parts and attached to the outer surface of a single endless water belt 5, so that the outer sides of the water absorbing members 4 in the area where each roller extends are radially separated from each other. As a result, the water-absorbing member 4 is not compressed or expanded due to the difference between the inner and outer circumferences, so that the water-absorbing member 4 can rotate smoothly and easily.

Therefore, according to the present invention, rainwater accumulated in a place to be removed, such as a tennis court, can be removed by one person in a short period of time, and there is an effect that a large amount of labor is not required for water removal.

Furthermore, the water tank 7 according to the present invention is particularly convenient because the body plate 6 can be installed in a large size, so that the amount of water stored can be increased and the number of times water is drained can be reduced.

Furthermore, since the pressure roller 10 and the squeezing roller 3 can be forcibly rotated by the rotational force of the pressure roller 2a via the belt 11, the water absorbing member will self-bite between the rotating squeezing roller and the squeezing roller. The operation is easy and the squeezing action is improved.

According to claim 2, the rollers such as the rotary roller 2.2 and the water conveying belt 5 are each divided into two rows and rotated individually for each row, so that the direction can be easily changed. There is an effect.
