DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water removal device capable of removing rainwater collected on a surface to be removed such as a tennis court, a soccer ground and its artificial turf surface, a track surface for an athletic track and the like in a wheelbarrow type.

[0002]

2. Description of the Related Art As a water removing device of this type, there is a device disclosed in Japanese Patent Application Laid-Open No. 4-44508, which was previously proposed by the present applicant. This prior art is an apparatus for removing water by contacting a water-absorbing member with a surface to be water-removed and causing the water-absorbing member to absorb water therein. A pressing roller is provided at a lower portion of the side plate so as to be pivotally supported between the respective side plates. A squeezing roller is pivotally supported between the uppermost two rotating rollers of the respective rotating rollers, and the lower surface of the squeezing roller and the respective An endless water-permeable belt having a plurality of divided water-absorbing members attached to the outer surface of the rotating roller and the pressing roller is rotatably stretched and stretched so that the upper portion thereof is flat, and the endless water-permeable belt is stretched. An empty space surrounded by the body plate and each side plate arranged in a liquid-tight manner between each side plate along the inside of the rotating roller as a water receiving tank,
Further, a drain valve is provided at a lower portion of the side plate,
A water removal device comprising a handle protruding from each side plate, a support roller pivotally supported by a water absorbing member below the squeezing roller, and a belt stretched between the press roller and the pressing roller. is there.

[0003]

The above-described prior art is based on the problem that the water-passing belt is moved together with a large number of water-absorbing members when it is moved by pushing or pulling a handle on a water-removed place such as a tennis court having a puddle. By rotating in a caterpillar manner via a rotating roller, a pressing roller, and a squeezing roller, a large number of water absorbing members rotate upward while being in contact with the surface to be removed, so that after the compression of the lower water absorbing member by the pressing roller is released. With the generated expansion force, each water absorbing member can successively absorb the water in the puddle.

[0004] Thereafter, the water absorbing members can be successively compressed by a squeezing roller and a pressing roller pivotally supported at the center of a water passing belt stretched almost flatly over the water receiving tank, and the water absorbing members absorb water. The water can be squeezed out one after another, and can flow naturally through a large number of holes in the water belt into the water receiving tank, and can be stored.The drained water can be drained to another location to remove the water to be removed. Things.

However, in addition to this conventional example, those disclosed in Japanese Unexamined Patent Application Publication No. 3-224905, which was filed by the applicant of the present invention, have a caterpillar type using a water-absorbing member, which has become heavier by absorbing water. When the water-absorbing member is lifted and forcibly rotated while forcibly bending and rotating the above-mentioned water-passing belt, which has been stretched through a large number of guide rollers as it rises to the upper part of the water-receiving tank, the water-absorbing member becomes heavy with the water-passing belt. Since it was necessary to rotate and raise, hand pushing work for water removal was extremely hard work, and in summer work was sweaty,
There is a problem that women and the elderly cannot remove water.

In addition to this prior art, an apparatus for removing water from a surface to be removed by a push plate, as disclosed in Japanese Patent Application Laid-Open No. Hei 8-31834 previously proposed by the present applicant, is constructed. In doing so, a front wheel is pivotally supported on the opposing pieces of a pipe-shaped frame having a substantially U-shape in a plane by a pivot, and a radial rotating rubber spatula for splashing water is pivotally provided between the opposing pieces by a central axis of the trunk. By interposing a reversing transmission member between the center shaft and the front wheel, the rotating rubber spatula is configured to be rotatable in the opposite direction to the front wheel, and a caster is provided at a lower center portion of the frame, There is also a well-known water removal device in which a push rod is protruded from the upper center of the frame, and a water collecting sled plate is provided at the front end of the frame facing piece so as to be inclined forward.

[0007] When an operator or the like applies a forward pushing force to the grip of the push rod on the surface to be removed, the front wheel and the rear wheel, which are in contact with the surface to be removed, advance while rolling. With the rotational force of the front wheel, the rotating rubber spatula rotates at an increased speed according to the gear ratio of each of the gears in the direction opposite to the front wheel around its central axis through a reversing transmission member composed of two large and small flat gears (or a tack belt). .

[0008] When the rotating rubber spatula reaches the pool water on the surface to be removed, the rotating rubber spatula can bounce the pool water forward in the traveling direction by the forward rotation force of the bending contact portion of the rotating rubber spatula. When the ground contact part rises from the surface to be removed, this time, the other radial rubber spatula on the lower side of the rotation successively touches the ground while rotating one after another in the direction of the water splashing, so that the accumulated water can easily jump off in the traveling direction one after another. Can be. That is, the water removing operation can be performed by converting the grip pushing force of the worker into the rotating force of the rotating rubber spatula and intermittently repelling the stored water.

At the time of the water removal, the water collecting sleds sloping forwardly and obliquely on the frame-facing piece can also remove and remove the pooled water on both sides of the rotating rubber spatula one after another while being gathered toward the center. Therefore, it is possible to remove water by pushing a considerably wide area in a belt shape, and the pushed water can be permeated into other places such as a coat or a track side or drained into a U-shaped groove.

However, in this conventional example, only the extremely flat surface can be removed, and in the case where the destination of the displacement water is far away, it is necessary to go to the far drainage place. However, there is an essential problem that it takes a lot of time to remove water, and it is also hard work.

According to the present invention, in order to eliminate the above-mentioned problems, a water absorption ring is pressed against a water-periphery surface of a rotary water-flow drum, and the water-absorbing ring is rolled over the reservoir along with wheels in front and behind the frame.
Water is absorbed by a water-absorbing ring, and water squeezed by a squeezing roller at the upper part of the ring is passed through the water-passing drum and stored in a water-receiving tank disposed in the drum, so that the water-removed surface is lightly removed with good workability. The purpose is to do.

[0012]

SUMMARY OF THE INVENTION The object of the present invention is to provide a device for removing water by bringing a water absorbing member into contact with a surface to be removed and absorbing the stored water by the water absorbing member. The water-passage drum is rotatably supported by its left and right side plates, and a water receiving tank having a drain plug at the lower part when opened at the upper part is provided inside the drum while maintaining a predetermined gap. A water-absorbing ring is fitted and fixed to the water-flowing peripheral surface of the water-flow drum, and the left and right projecting portions of the horizontal axis are pivotally supported by left and right support pieces, respectively. These support pieces are fixed to a substantially trapezoidal frame-shaped frame, and squeezing rollers for pressing the upper part of the water absorbing ring are horizontally mounted on left and right supports protruding from the frame, and a pushing rod is provided on the frame. And the front and rear wheels.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. First, as an example of an embodiment of the present invention, a water absorbing member such as a sponge is brought into contact with a surface to be removed such as a tennis court to absorb water such as rainwater by the water absorbing member so as to remove water. , FIG. 1,
As shown in FIG. 5, a horizontal shaft 1 made of a tough metal round bar or the like is provided with two right and left perforated side plates 3 each made of a stainless steel mesh or a perforated plate having a strong water passage peripheral surface 2A. 3 and 5 so as to be rotatable individually.

2 and 5 in these drums 2.
As shown in FIGS. 1 and 5, water receiving tanks 5 each having a drain plug 4 such as a rubber plug at the lower part when opened at an upper portion are provided with predetermined gaps therebetween, and these water receiving tanks 5 are respectively attached to left and right side plates. At 6, the water receiving tank 5 is eccentrically mounted on the horizontal axis 1 so as not to be turned upside down so as to be pivotally supported in a so-called “jijirobe” type. A thick water-absorbing ring 7 such as a ring is fitted and fixed against the elasticity as shown in the above figures.

A frame F is formed by pivotally supporting the left and right protruding portions 1A of the horizontal shaft 1 on the left and right support pieces 8, respectively, and forming these support pieces 8 in a substantially trapezoidal frame shape using a tough material such as a reinforced plastic pipe. The squeezing roller 10 which presses the upper part of the water absorbing ring 7 on the left and right supporting pieces 9 which are respectively protruded from the upper parts of the left and right frames, is fixed to the intermediate side surface of the left and right frames.
The left and right push rods 11 having the handle H on the frame F and the front and rear wheels 12 are provided as shown in the above-described drawings to constitute a water removal device according to the present invention.

In the illustrated embodiment, the horizontal axis 1
In the above description, an example was described in which two water-supplying drums 2, water removal tanks 5, water-absorbing rings 7, and squeezing rollers 10 were respectively arranged in parallel. This is a single-part type hand-operated water removal device assembled by using one each of the water passage drum 2, the water receiving tank 5, the water absorption ring 7, and the squeeze roller 10 which are wider than each other.

Since the water removal device of the present invention is constructed as described above, it is necessary to remove the water removal device such as a tennis court having a puddle as shown in FIGS. When the handle H is moved by pushing or pulling on the water place, the water absorption ring 7 comes into contact with the wheel 12 together with the wheel 12,
Since the water absorbing ring 7 rolls upward together with the water-permeable drum 2 while being compressed by about half of its thickness, a water puddle is formed at the lower part of the water absorbing ring 7 rotating by the expansion force generated after the compression of the lower part of the water absorbing ring 7 is released. Water W can be continuously absorbed one after another.

Thereafter, the water-absorbing ring 7 that has been absorbed by the squeezing roller 10 can be successively pressed against the upper water-permeation peripheral surface 2A of the water-permeation drum 2 above the opening 5A of the water-receiving tank 5, and the water-absorption ring 7 can be compressed. The water absorbed by the ring 7 can be squeezed out one after the other at the upper part, and can flow naturally into the water receiving tank 5 through the water flow peripheral surface 2A of the water flow drum 2 to store the water. The drainage can be removed by inserting a finger through the hole 3a of the side plate 3 to remove the drain plug 4 and draining it to another place.

Although the load applied to the horizontal axis 1 increases as the amount of stored water W in the water receiving tank 5 increases, in the present invention, the horizontal axis 1 is pivotally supported by the supporting piece 8 on the frame F, and Since the frame F is moved on the surface to be removed by the wheels 12, the degree of compression of the water absorbing ring 7 can be maintained at about half the thickness regardless of the amount of the water W in the water receiving tank 5.

Further, as in the embodiments shown in the above-mentioned figures, the water passage drum 2, the water removal tank 5, the water absorption ring 7, and the squeeze roller 10 are made slightly narrower, and these are attached to the horizontal shaft 1 and the pivot 10A. On the other hand, in the case of two in parallel, the left and right two water absorbing rings 7 and the squeezing rollers 10 rotate left and right separately, so that it is easy to run a curve at the time of water removal.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The pivot 10A of the squeeze roller 10 is shown in FIG.
As shown in FIG. 5, specifically, the upper vertical hole 9A of the support piece 9
It is pivotally supported on a bearing piece 10B which can be fixed vertically with a screw n so that the pressing depth of the squeezing roller 10 with respect to the water absorbing ring 7 can be adjusted and fixed with a variable dimension of about 5 to 15 mm.

The front and rear wheels 12 may be casters at the rear, as shown in FIGS. 1 and 2.
In each figure, the reference numeral n indicates a set screw, the reference numeral P indicates a retaining pin which is inserted and fixed to the horizontal shaft 1, and the reference numeral S indicates a spacer spacer ring. All the members other than the water absorbing ring 7 as well as the respective members are made firmly by using a tough material such as reinforced plastic or metal, and these mounting parts are firmly attached and assembled.

Further, in order to pivotally support the horizontal axis 1 without turning the water receiving tank 5 upside down, when the water receiving tank 5 is empty, the pivot hole of the side plate 6 is slightly formed so that the lower half thereof becomes heavier. When the lower half is made heavy by being eccentric upward, or when the center of the water receiving tank 5 is pivotally supported, a weight may be disposed below the pivot point.

Further, as shown by a chain line in FIG. 1, the height of the handle H at the tip of the push rod 11 can be changed by changing the attachment point of the push rod 11 to the frame F or by using a letter-shaped push rod. The handle H can be low or high.

[0025]

According to the present invention, a horizontal axis is used to constitute a device for removing water by contacting a water-absorbing member with a surface to be water-removed to absorb water from the water-absorbing member by adopting the above-described embodiment. 1, a water receiving drum 2 is rotatably supported by its left and right side plates 3, and a water receiving tank 5 having an open upper part and a drain plug 4 at a lower part is provided inside the drum while maintaining a predetermined gap. The left and right side plates 6 pivotally support the horizontal shaft 1, and a water absorbing ring 7 is fitted and fixed on the water-peripheral surface 2 </ b> A of the water-flow drum 2. 1A is pivotally supported on left and right support pieces 8, respectively, and these support pieces 8 are fixed to a substantially trapezoidal frame-shaped frame F, and the upper portions of the water absorption rings 7 are attached to left and right support pieces 9 protruding from this frame. The squeezing roller 10 to be pressed is horizontally supported on the shaft, and the pressing rod 11 and the front and rear wheels are mounted on the frame F. 12, the water absorption ring fixed on the water passage peripheral surface of the rotary water passage drum is rolled on the pool along with the wheels 12 at the front and rear of the frame, so that the water squeezed by the squeezing roller at the upper part of the water absorption ring is passed through the water passage. After the water drum, the water can be stored in a water receiving tank pivotally supported inside the drum, and there is a real benefit that the surface to be removed can be easily and easily removed by women, women, and the elderly with good workability.

In particular, according to the present invention, the ground compression degree of the water absorbing ring 7 can be kept constant by the wheels 12 of the frame F regardless of the amount of the stored water W in the water receiving tank 5, so that the maximum water absorbing capacity is always maintained. There are some benefits, such as maintenance.

According to the second aspect of the present invention, in addition to the above benefits, the lower ground contact portion of the two left and right water absorbing rings 7 and the pressing portion of the upper squeezing roller 10 are separately provided on the left and right sides. Since the water absorption rings 7 rotate independently of each other, the effect that the water traveling on the curve can be easily removed can be added.
