Abstract

PURPOSE:To efficiently remove rainwater by rotatably extending a stepless water chute belt having a water absorption member divided into many sections, over the external surfaces of rotational and pressing rollers, absorbing stagnating water, and squeezing and collecting the rainwater with a squeezing roller. CONSTITUTION:A motor M is driven to cause the forced rotation of a pressing roller 2a, and a stepless water chute belt 5 fitted with many water absorption members is turned like a catapillar via many rotational rollers 2 and squeezing rollers 3. Furthermore, many water absorption members 4 are turned, while kept in contact with a water removing surface, and water is absorbed from pools sequentially via the compression and expansion of the aforesaid members 4 due to the pressing roller 2a. Thereafter, the water absorbing members 4 are compressed one after another with the squeezing and pressing rollers 2 and 3, and the absorbed water is sequentially squeezed out. The water is thereby caused to naturally fall into a water reservoir 7 through many holes of the water chute belt 5, reserved in the aforesaid reservoir 7 and then discharged. According to the aforesaid construction, rainwater can be discharged by one person in a short time without any need of much labor.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water removal device, and more specifically, a caterpillar-type water absorption device that removes a large amount of water accumulated on courts, road surfaces, etc. using the power of a prime mover. This invention relates to a self-propelled water removal device that can simply and easily remove water using members.

[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 conventional methods described above, removing rainwater from a rectangular court (approximately 26 inches) surrounded by a side line and a baseline requires a great deal of effort. It is not something that can be done effectively even if it is carried out by a large number of people.

Pushing rainwater out of the court with a paddle is like scooping it up in a colander, which is extremely inefficient, and pushing it out with bombs is also inefficient, considering the amount of time and physical effort it takes.

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] An object of the present invention described above is to provide a device for removing water from a surface to be water-removed by bringing a water-absorbing member into contact with the 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 periphery of the pair of side plates except for the upper and lower parts, and a pressing roller is provided at the lower part of the side plates, respectively, pivotably supported between the respective side plates, and among these rotating rollers, the top two A squeezing roller is pivotally supported between the rotating rollers, and an endless water passing belt is provided with a plurality of water-absorbing members attached to the outer surfaces of the lower surface of the squeezing roller and the outer surfaces of each of the rotating rollers and the pressing roller, the upper part of which is flat. A space surrounded by a body plate and each side plate, which are arranged so as to be rotatable and spanned so that is used as a water tank, and a drain valve is provided at the lower part of the side plate, a handle is provided protruding from each of the side plates, and a presser roller is pivotally supported with a water absorbing member sandwiched between the lower part of the squeezing roller,
A belt is passed between this pressing roller and the pressing roller, and the driving shaft of the prime mover provided on the reinforcing stays protruding from each of the side plates is connected to the pressing roller via a transmission member such as a V-belt or a pulley. It is achieved by doing.

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

Furthermore, casters may be provided on the reinforcing stay at the lower part of the motor installed on the reinforcing stay.

[Function] When you hold the handle on a place where water is to be removed, such as a tennis court where there is a puddle, and forcibly rotate the pressure roller using the power of the prime mover via the transmission member, the water conveying belt will move along with a large number of water absorbing members to the pressure roller. It rotates in a caterpillar style through a large number of rotating rollers and squeezing rollers using the rotational force of .

As the water belt rotates, a large number of water absorbing members rotate while coming into contact with the water-removed surface, so the lower water absorbing members are compressed by the expansion force generated after being released from compression by the pressure roller. It can absorb water from puddles 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.

If casters are provided on the lower surface near the tip of the reinforcing stay, the water removal device will become even more stable and self-propelled.

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 caster or roller that supports the weight of the prime mover M and prevents the entire device from leaning forward during use. If the push angle of a is adjusted to an appropriate level by hand, or if the location of the pressure roller 2a is moved slightly closer to the prime mover side, the entire device will not lean forward even if the casters or rollers 14 are 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.

Use the handle 9 on a place where water is to be removed, such as a tennis court with puddles.
When the pressure roller 2a is forcibly rotated by the power of the prime mover M via the transmission member ■ and the pulley 2c, the water conveying belt 5 is rotated together with a large number of water absorbing members 4 by the rotational force of the pressure roller 2a. 2 and a squeeze roller 3, it rotates in a caterpillar manner.

As the water conveying belt 5 rotates, the lower part of the large number of 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 of the water absorbing members 4, 4 can be compressed one after another by a squeezing roller 3 and a press 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.

, and there is a squeezing roller 3 and a pressing roller 1° in the middle of the upper part of the water conveying belt 5, which is stretched flatly.
The squeezed water flows down into the water receiving tank 7 directly below.

In addition, the rotating roller 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 member 4.4 in this invention is divided into many parts and attached to the outer surface of one endless water belt 5,
The water absorbing members 4, 4 at the spanning portion of each roller pass 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.

That is, when the pressure roller 2a is forcibly rotated by the power of the prime mover M, the rotational force of the suppression roller 2a causes the water belt 5 to rotate around the multiple rotating rollers 2, 2 in a caterpillar manner, and the water absorption member 4 is rotated in a caterpillar manner. 5 and between the flanges 2' and 2' of the rotating roller 2.2, and as shown in FIGS. Rainwater on the court surface is absorbed, and the absorbed water absorption member 4 is compressed between the squeezing roller 3 and the pressing roller 10, and the absorbed rainwater is squeezed out into the water receiving tank 7 through the drainage hole 12 of the water belt. The water-absorbing member 4 which has recovered its water-absorbing power is fed out, and the rainwater on the court surface is collected into the water-receiving tank 7 by repeatedly moving the device back and forth to the water surface E to be removed.

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 upper surface of the area to be water removed, it is replaced when it wears out or when its water absorbing function deteriorates.

When replacing this, each roller 2. 2a and 3.10 can be freely replaced by removing them from their pivots 2b, and after use, they can be washed with water by running them between the removed rollers to remove moisture and dry them.

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.

Another embodiment of the present invention shown in FIG. 7 is a clutch K with two reducers on the left and right sides of a two-shaft motor M.

The driving shafts m and m, which have passed through K, are connected to the left and right pressing rollers 2, respectively.
By connecting a and 2a to transmission members V and (2) such as belts, it is possible to easily drive the vehicle in a so-called left and right wheel drive system.

Furthermore, in another embodiment of the present invention shown in FIG. By connecting to the output shaft 21.21 of this differential 20 and extracting power from it, the left and right pressing rollers 2a.

2a is forcibly rotated to facilitate straight forward movement, right turns, and left turns using the differential gear 2D.

In each of the figures, the same reference numerals as those in the embodiments of the present invention indicate equivalent parts or parts having the same effect.

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

In the water removal device of claim 1, when the handle 9 is held over a place where water is to be removed, such as a tennis court where there is a puddle, and the pressure roller 2a is forcibly rotated by the power of the prime mover via the transmission member, the water flows. The belt 5, together with a large number of water absorbing members 4, is rotated by a large number of rotating rollers 2, 2 and a squeezing roller 3 by the rotational force of a pressing roller.
It rotates in a caterpillar style.

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 removed, so that after the lower water absorbing member 4.4 is released from compression. The generated expansion force 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 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 press 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 that it does not spill to the side. There is no.

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.

In addition, since the pressing roller 10 and the squeezing roller 3 can be forcibly rotated by the rotational force of the pressing roller 2a via the bell) II, the water absorbing member will self-cut into the space between the rotating squeezing roller and the squeezing roller. , the operation can be performed easily and the throttling action is improved.

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

Moreover, in claim 3, a water removal device that can self-propel even more stably can be obtained.
