Description

  The present invention relates to a water absorption device used for sucking up liquids such as water in farm work, fire fighting work, civil engineering work, ship bilge drainage, etc., and more specifically, water absorption capable of stably sucking up water regardless of water depth. Relates to the device.

  Conventionally, when sucking up water for farm work or fire fighting work, for example, a water absorption device 100 as shown in FIG. 6 has been used. This water absorbing device 100 has a cylindrical body 101 provided with a large number of small holes 102, and a hose 2 drawn out from a fire engine or the like is connected to a coupling 103 attached to one end thereof. It is configured. And this water absorption apparatus 100 is thrown into a river etc., and the water required for the said operation | work is ensured by sucking up water with a pump (not shown).

  However, when the conventional water absorbing device 100 is introduced into a place where the water depth is shallow as shown in FIG. 6, the entire tubular body 101 may not be immersed in the water, and air may be sucked from the small hole 102. . If air is sucked in this way, not only the water absorption efficiency is lowered, but also the force received by the operator becomes unstable, and there is a problem that the water absorption work itself becomes dangerous. Since the conventional water absorption device 100 has a cylindrical body 100 that is approximately 10 centimeters high, it cannot absorb water at a depth of 15 cm or less. In rivers, it was sometimes difficult to use.

  In view of such circumstances, the present inventor once provided a strainer that is disposed on the bottom of the water and serves as a water suction port, a cover that surrounds the strainer except for the bottom side thereof, a penetrating through the cover, and a strainer. There has been proposed a water absorbing device having a coupling to be connected and a support leg that protrudes downward from the bottom of the cover and supports the cover from the water bottom (Patent Document 1).

  The water-absorbing device of Patent Document 1 uses negative pressure to suck in air as long as the bottom of the cover is immersed in water even when the water depth is shallow and the entire cover is not immersed in water. It was excellent because it could suck up water.

  However, because of the structure of the water absorption device of Patent Document 1, the side plate portion of the cover needs to be strong enough to support the strainer in a cantilevered manner, and the weight of the strainer becomes heavy to ensure the strength. There was a problem. Therefore, it is not easy to carry the water absorbing device of Patent Document 1 and it is difficult to say that the water absorbing device is excellent in portability. In addition, there is a problem that the strainer's small holes are clogged by sucking algae, dust, and the like together with water.

  Accordingly, the present inventor has provided a box-shaped case disposed on the bottom of the water and provided with an opening on the bottom of the water, and an end plate on one end in the front-rear direction of the case, and a connecting portion for attaching the coupling. And a filter disposed in the case and interposed between the opening and the connecting portion, and a support leg that protrudes downward from the bottom of the case and supports the cover from the water bottom. A water absorption device was newly proposed (Patent Document 2).

  Since the water absorption device of Patent Document 2 does not include the heavy strainer as in Patent Document 1, it is lightweight and excellent in portability, and a filter interposed between the opening and the connection portion allows the algae to be used. Because it removes trash and dust, it is excellent because it does not cause clogging.

  As described above, the water absorbing device of Patent Document 2 was light and excellent in portability, but although it was light, the water absorbing device that sucked in water was heavy, particularly in a place where the water depth was deep When the water absorption device was put into the tank, the lifting work was not easy. Moreover, since it arrange | positions at the bottom of a water, algae, garbage, etc. are sucked in often, and there also existed a problem that a suction | attraction force will fall, if filter maintenance is not performed frequently.

  Therefore, the present invention has been made in view of the above problems, and the problem to be solved is that water can be stably absorbed regardless of the water depth, and the lifting work is easy even when the water depth is deep. It is in providing the water absorption apparatus which can reduce the frequency of water as much as possible.

  In order to solve the above problems, a water absorbing device according to the present invention includes a device main body having a water inlet and a drain, a pump for sucking water from the drain of the device main body, and the device main body and the pump. It has a hose to be connected, and the apparatus main body includes a float for floating the apparatus main body on the water surface, so that water can be absorbed in the vicinity of the water surface from the water inlet.

  In the water absorbing device of the present invention, it is preferable that the float is provided on a lower surface portion or / and a lower side portion of the device main body. Moreover, it is preferable that the said water inlet is provided in the lower surface part of the said apparatus main body, and it is more preferable that the filter is provided between the said water inlet and the said drain outlet.

  Since the water absorbing device of the present invention includes a float for floating the device main body on the water surface, when the device main body is thrown into a river or the like, it always floats on the water surface. Therefore, water near the water surface is absorbed from the water inlet, and can be absorbed even at a shallow depth. Moreover, since the apparatus main body does not sink in water, even if it is inserted in a deep water place, the lifting work is the same as when the water depth is shallow, and the burden on the operator is small. Moreover, since there are fewer algae and the like in the vicinity of the water surface compared to the bottom of the water, the opportunity to suck them in is reduced, and the frequency of maintenance can be greatly reduced. Thus, the water absorbing device of the present invention can be used stably in the same manner whether the water depth is shallow or deep.

  In addition, the water absorbing device in which the float is provided in the lower surface portion or / and the lower side portion of the device main body is provided with a float in the lower surface portion or / and the lower side surface portion of the device main body. Most of the water is located above the water surface, and water can be stably absorbed even in a place where the water depth is very shallow.

  In particular, the water-absorbing device in which the water-absorbing port is provided in the lower surface portion of the device main body is provided with a water-absorbing port in the lowermost portion of the device main body, so long as there is water, without sucking air, It can absorb water stably.

  As described above, the present invention sucks up water in the vicinity of the water surface with less algae and the like compared to the bottom of the water, but there are algae and dust on the water surface. Even in such a case, algae and the like are removed by a filter by providing a filter between the water inlet and the drain outlet like a water absorption device in which a filter is provided between the water inlet and the drain outlet. As a result, problems such as algae and garbage mixed in the sucked-up water are eliminated.

Embodiment 1
A water absorption device 10 according to Embodiment 1 of the present invention shown in FIG. 1 includes a device main body 1 having a water suction port 1a and a drain port 1b, a pump P for sucking water from the drain port 1b of the device main body 1, and a device main body. 1 and hose 2 that connects pump P, and is used for sucking up liquids such as water in agricultural work, fire fighting work, civil engineering work, ship bilge drainage, and the like.

  As shown in FIGS. 2 and 3, the apparatus main body 1 includes a front plate 10a, a rear plate 11a, an arch-shaped top plate 12a, and left and right side plates extending downward from both side ends of the top plate 12a. 13a, 13a, and a box-shaped box body, the lower surface portion of which is open, and the opening serves as a water inlet 1a for sucking water into the apparatus main body 1.

  If the water inlet 1a is provided in the lowermost part of the apparatus main body 1 in this way, the water inlet 1a is always in contact with water even if the apparatus main body 1 is inserted into a river having a very shallow water depth. If there is, there is water absorption. Moreover, the labor of providing a separate water inlet can be saved and the production cost can be reduced.

  As shown in FIGS. 2 and 3, a circular opening is formed in the front plate 10a of the apparatus main body 1, and a drain outlet 1b for discharging water absorbed from the water inlet 1a is provided in the opening. ing. The drain port 1b is composed of a cylindrical strainer 10b in which a large number of holes 11b are drilled and a coupling 12b to which one end of the hose 2 is connected. The water absorbed from the water suction port 1a It flows into the inside of the strainer 10b from 11b and is discharged to the hose 2.

  Further, the float 3 which is the greatest feature of the present invention is provided on three side surfaces of the apparatus body 1, that is, the rear plate 11a and the left and right side plates 13a and 13a. The float 3 is provided so that the apparatus body 1 floats on the water surface when the apparatus body 1 is put into a river or the like. In this embodiment, most of the apparatus body 1 floats on the water surface (rather than the water surface). It is provided on the lower part of the rear plate 11a and the left and right side plates 13a, 13a.

  Thus, when the float 3 is provided in the lower part of the apparatus main body 1, even in a river or the like where the water depth is shallower than the height of the apparatus main body 1, the water inlet 1a may come into contact with the water bottom and the water inlet 1a may be blocked. In addition to this, by providing the water inlet 1a at the lowermost part of the apparatus body 1 as described above, the water absorbing device 10 of the present invention can absorb water in any place as long as there is water. Can be done.

  The float 3 may be an air bag, for example, as long as it can float the device body 1 on the water surface. In the present embodiment, the float 3 is lightweight, has high buoyancy, and is processed into various shapes. A float 3 made of styrene foam is used.

  As described above, the float 3 of the present embodiment is provided on the three side surfaces (the rear plate 11a and the left and right side plates 13a, 13a) except the front plate 10a, and the apparatus in which the float 3 is provided at such a location. When the main body 1 is thrown into a river or the like, the front side of the apparatus main body 1 is slightly sunk, but since the hose 2 is connected to the apparatus main body 1, the apparatus main body 1 is slanted as shown in FIG. The force pulled upward is acting.

  Therefore, in the water absorption state to which the hose 2 is connected, the horizontal state of the apparatus main body 1 is maintained, and the lower end on the front side of the apparatus main body 1 (particularly in the vicinity of the lower end of the front plate 10a) is separated from the water surface. The problem of sucking air from the gap is eliminated.

  As described above, the float 3 of the present embodiment is provided on three side surfaces (the rear plate 11a, the left and right side plates 13a, 13a). The float 3 is provided on the lower surface portion of the apparatus main body 1 (the rear plate 12a). In this case, it is necessary to use the float 3 with a slight buoyancy so that the water inlet 1a is in contact with water.

  As described above, by providing the float 3 in the apparatus main body 1, when the apparatus main body 1 is thrown into a river or the like, the apparatus main body 1 is in a state of floating on the water surface. It becomes water near the water surface. Near the water surface, there are fewer algae and the like than the bottom of the water. However, even though the water surface is present, algae and dust are present, and if the algae and dust are sucked up, the pump P may be damaged. In order to cope with this, the apparatus main body 1 of this embodiment is provided with a filter 4 that removes foreign matters such as algae and dust between the water inlet 1a and the drain 1b.

  The filter 4 is a curved plate in which a mesh or a large number of small holes are formed. As shown in FIG. 3, the filter 4 is provided in a lower portion (between the water inlet 1a and the strainer 10b) inside the apparatus main body 1. By providing such a filter 4 inside the apparatus main body 1, algae and the like are removed by the filter 4, and there is no problem that algae and dust are mixed in the sucked-up water. It will not break down. Of course, since there are many water passages in the filter 4, there is no influence on the suction force for sucking up water.

  As shown in FIG. 1, the apparatus main body 1 has one end of the hose 2 connected to the coupling 12b of the drain port 1b. The other end of the hose 2 is connected to a pump P that is a driving force for sucking water, and the pump P is connected to another hose 2 (on the right side of the pump P in the drawing) that discharges the sucked water to the outside. A hose 2) is connected.

  As the hose 2 and the pump P, known ones are used as appropriate. When the pump P is operated, a negative pressure is generated inside the water absorbing device 1, and water is sucked up from the water inlet 1a of the device body 1 floating on the water surface. It is structured.

  The water sucked up from the water intake port 1a flows into the hose 2 connected to the coupling 12b from the small hole 11b of the strainer 10b, and is discharged to the outside from the other hose 2 connected to the pump P. It is used for agricultural work, fire fighting work, civil engineering work, etc.

  At this time, as described above, since the entire area of the water inlet 1a is always in contact with water, once the air inside the apparatus body 1 is once sucked, the inside of the apparatus body 1 is filled with water, and thereafter the air is discharged. Without sucking, it is possible to stably suck up only water, and there is no fear that the water absorption work becomes dangerous as in the past.

  Although not shown, the pump P and the two hoses 2 and 2 (the hose 2 connected to the apparatus main body 1 and the hose 2 for discharging to the outside) are connected through a substantially T-shaped joint. May be.

  As is apparent from the above description, the water absorbing device 10 of the present invention is provided with the water inlet 1a at the lowermost portion of the device main body 1, and in addition to the three side surfaces (rear plate 11a, left and right side plates) of the device main body 1. By providing the float 3 for floating the apparatus main body 1 on the water surface in the lower part of 13a, 13a), it becomes possible to absorb only water without sucking air even in a place where the water depth is very shallow.

  In addition, the water near the surface of the water has fewer algae, etc. than the bottom of the water, so the opportunity to inhale them is reduced and the frequency of maintenance can be greatly reduced. If algae is inhaled, it is removed by the filter 4 Therefore, it is possible to prevent the failure of the pump P due to the cause.

  Further, as described above, the apparatus main body 1 always floats on the surface of the water, and the apparatus main body 1 does not sink into the water. It is the same and there is little burden on the worker. Thus, the water absorbing device 10 of the present invention can be used stably in the same manner regardless of whether the water depth is shallow or deep.

The coupling 12b can have its one end (exit side) directed upward depending on the degree of screwing, so that the hose 2 is not extremely bent even in a river having a narrow width and far from the water surface. However, it can be connected to the apparatus main body 1A.

  A float 3 for floating the apparatus main body 1A on the water surface is provided on the lower side of the three side surfaces (rear plate 11a, left and right side plates 13a, 13a) excluding the front plate 10a of the apparatus main body 1A. Thereby, since the apparatus main body 1A of this embodiment also floats on the water surface like the apparatus main body 1 described above, the water near the water surface is absorbed.

  The top plate 12a of the apparatus main body 1A is provided with a downward U-shaped gripping portion 14a that is convenient to carry. Unlike the apparatus main body 1 described above, the apparatus main body 1A is light in weight because the strainer 10b does not exist, and is excellent in portability because the gripping portion 14a is provided.
