Description

Technical Field

[0001] The utility model relates to a drainage device for an air-tired bamboo raft, belonging to the technical field of drainage facilities. Background Art

[0002] At present, for drainage in water conservancy projects, a water pump is usually directly placed in a sump for drainage. For example, the utility model patent with the publication number CN220099957U discloses a drainage device for a deep foundation pit, which includes a support frame, connecting rods fixed at both ends of the two support frames, a fixed disk fixed at the middle section of the support frame, a winding drum rotatably arranged on the two fixed disks, a suspension cable wound and installed on the winding drum, a water pump installed at the bottom area of the suspension cable, a water inlet arranged at the bottom of the water pump, a filter screen wound and installed at the water inlet, and a filtering component installed at the outer edge of the filter screen for positioning. This drainage device for a deep foundation pit can drive the winding drum to rotate through a servo motor, move the suspension cable to a specified position during the rotation of the winding drum, and lower the water pump to a specified drainage position. Another example is the utility model patent with the publication number CN204212169U, which discloses an automatic sump pumping device, including a sump and a submersible pump arranged at the bottom of the sump. The outlet pipe of the submersible pump is placed outside the sump. A base of the pumping device is arranged at the mouth of the sump. A support rod is arranged on the base. The travel switch of the submersible pump is arranged on the support rod. One end of a cable is connected to the travel switch, and the other end is connected to the submersible pump. A lifting rod is also arranged on the base. The bottom end of the lifting rod is connected to a floating cylinder. The upper end of the lifting rod passes through a limit sleeve arranged on the base and is perpendicular to the base. A trigger rod is arranged on the lifting rod. The trigger rod cooperates with the travel switch to control the opening and closing of the travel switch during the lifting and lowering of the lifting rod. This automatic pumping device can be applied to the construction of sump pumping in various foundation pit water treatment facilities. The above technologies have their own advantages in the control of the water inlet depth of the water pump and the automatic control of starting and stopping, and are respectively applicable to their respective suitable occasions. However, since the sump is at the bottom of the foundation pit, when the water pump is placed in the sump, it is very easy to touch the slag stones and hard soil in the sump, causing damage to the water pump, which not only increases the maintenance cost of the water pump but also affects the progress of the project. Summary of the Utility Model

[0003] To overcome the above defects of the prior art, the utility model provides a drainage device for an air-tired bamboo raft to facilitate drainage in sumps and other occasions.

[0004] The technical solution adopted by the utility model to achieve the above purpose is: a drainage device for an air-tired bamboo raft, including a bamboo raft, and a plurality of vertically downward extending hanging cages are fixedly arranged on the bottom surface of the bamboo raft. A water pump (or submersible pump, drainage pump) is fixedly installed in the hanging cage, and a gap is left between the outer wall of the water pump and the inner wall of the hanging cage.

[0005] Preferably, there is a gap between the bottom surface of the water pump and the bottom surface of the cage, that is, the bottom surface of the water pump is higher than the bottom surface of the cage.

[0006] Preferably, several cages are evenly distributed on the bottom surface of the bamboo raft.

[0007] Further, the number of cages is four, and the four cages are respectively arranged at the four corners of the bottom surface of the bamboo raft.

[0008] Preferably, a drain pipe is connected to the drain outlet of each water pump.

[0009] Preferably, the drain pipe is a flexible pipe, such as a rubber hose or a plastic hose.

[0010] Preferably, a floating body is provided on the drain pipe.

[0011] The floating body can be a floating cylinder, a floating ball, a foam block or other objects suitable for floating on water.

[0012] Preferably, a bamboo glue board is fixedly provided on the top surface of the bamboo raft.

[0013] The bamboo glue board can cover the entire area of the bamboo raft or be smaller than the area of the bamboo raft.

[0014] Preferably, a rope is connected to the bamboo glue board or the bamboo raft.

[0015] Preferably, the bamboo raft is fixed by tying bamboo poles that crisscross each other.

[0016] Preferably, the air-tire bamboo raft water pumping and draining device further includes air tires. The number of air tires is the same as the number of cages, and they are sleeved on the outside of the cages one by one and fixedly connected to the bottom surface of the bamboo raft.

[0017] The beneficial effects of the present utility model are as follows: Since the suspension cage is located below the bamboo raft, the distance between the suspension cage and the water pump from the water surface is effectively controlled, and this distance does not change due to different water depths of the water body, effectively ensuring the smooth implementation of the pumping operation; Since the water pump is arranged inside the suspension cage, the suspension cage can effectively protect the water pump. During the dewatering construction of the sump, the water pump will not be damaged by touching the slag, stones and hard soil in the sump. In addition, the suspension cage can also intercept some sundries in the sump, avoiding the blockage of the water inlet of the water pump during the dewatering process; Since there is a spacing between the bottom surface of the water pump and the bottom surface of the suspension cage, even if the suspension cage touches the bottom in the sump, the water pump will not be damaged or the water inlet blocked due to touching the bottom; The setting of the air tire can increase the overall buoyancy of the drainage device in the water, making the upper part of the drainage device (mainly referring to the bamboo raft and the air tire) always float on the water surface, and the lower part (mainly referring to the suspension cage and the water pump) always suspended in the water. This can not only avoid the drainage device sinking to the bottom due to insufficient buoyancy of the bamboo raft, but also enable the drainage device to descend as the water level drops (until the suspension cage descends to the base), ensuring the smooth progress of dewatering and the dewatering effect, and also facilitating the removal of the drainage device from the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 is the front view structural schematic diagram of an embodiment of the present utility model;

[0019] Figure 2 is Figure 1 the bottom view structural schematic diagram of the embodiment. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] See Figure 1 and Figure 2, the present utility model discloses a pneumatic tire bamboo raft pumping and drainage device, which is mainly used for dewatering construction in water conservancy projects. It includes a bamboo raft (having a certain buoyancy and capable of floating on the water surface) 1. The bamboo raft can be formed by binding and fixing vertically and horizontally crisscrossed bamboo poles. A number of vertically downwardly extending hanging cages 2 are fixedly provided on the bottom surface of the bamboo raft. The hanging cages are preferably made of steel cages to ensure structural strength. The hanging cages can be cylindrical (with a circular cross-section) or rectangular tube-shaped (with a rectangular cross-section), and are bound and fixed on the bamboo raft. A water pump (also known as a submersible pump or drainage pump) 3 is fixedly installed (such as by binding and fixing) inside the hanging cage. There is a spacing between the outer wall of the water pump and the inner wall of the hanging cage, and the spacing can be 5 - 20 cm. With such a setting, during the dewatering construction process, the hanging cage can effectively protect the water pump, and the water pump will not be damaged due to touching the slag, stones, and hard soil in the sump. In addition, the hanging cage can also intercept some debris in the sump, avoiding the debris blocking the water inlet of the water pump during the dewatering process.

[0021] Preferably, there is a spacing between the bottom surface of the water pump and the bottom surface of the hanging cage, and the spacing can be 5 - 20 cm, that is, the bottom surface of the water pump is higher than the bottom surface of the hanging cage. With such a setting, even if the hanging cage touches the bottom in the sump, it will not cause damage or blockage of the water inlet of the water pump due to touching the bottom.

[0022] A number of the hanging cages are preferably evenly distributed on the bottom surface of the bamboo raft, so that the pumping and drainage device can float stably in the water during operation without being overweight. A preferred implementation is that the number of the hanging cages is four, and the four hanging cages are respectively arranged at the four corners of the bottom surface of the bamboo raft.

[0023] The drainage ports of each water pump are all connected with drain pipes (not shown in the figure). The drain pipes are preferably flexible hoses, such as rubber hoses or plastic hoses, so that they have a certain flexibility and can float on the water surface. During the dewatering construction process, the drain pipes can extend outside the cofferdam of the foundation pit, that is, the drainage ports of the drain pipes are located outside the cofferdam of the foundation pit, so as to discharge the water pumped by the water pump from the foundation pit.

[0024] Preferably, floating bodies are provided on the drain pipes. The floating bodies can be floating cylinders, floating balls, foam blocks or other objects suitable for floating on the water, so as to increase the buoyancy of the drain pipes, so that during the dewatering construction process, the drain pipes can always float on the water surface.

[0025] The wires of the water pump can be arranged along the drain pipes, such as being tied to the drain pipes.

[0026] Preferably, a bamboo glue board 4 is fixedly arranged on the top surface of the bamboo raft to increase the structural strength of the bamboo raft. The bamboo glue board can cover the entire area of the bamboo raft or be smaller (slightly smaller) than the area of the bamboo raft.

[0027] Preferably, a rope (not shown in the figure) is connected to the bamboo glue board or the bamboo raft. Through the rope, the drainage device can be tied and fixed on the cofferdam slope of the foundation pit, preventing the drainage device from floating away during the drainage construction process and facilitating the staff to pull and retrieve it.

[0028] The air-tired bamboo raft drainage device preferably further includes air tires 5. The number of air tires is the same as the number of the hanging cages, and they are sleeved (preferably coaxially sleeved) on the outside of the hanging cages one by one and fixedly connected (such as tied and fixed) to the bottom surface of the bamboo raft. The vertical dimension of the air tires should be appropriate to ensure that there are enough water-permeable gaps on the hanging cages that are not covered / blocked to avoid interfering with the operation of the shaft water pump. The setting of the air tires can increase the overall buoyancy of the drainage device in the water, making the upper part (mainly referring to the bamboo raft and the air tires) of the drainage device always float on the water surface and the lower part (mainly referring to the hanging cage and the water pump) always suspended in the water. This can not only avoid the drainage device sinking to the bottom due to insufficient buoyancy of the bamboo raft but also enable the drainage device to descend as the water level drops (until the hanging cage descends to the base), ensuring the smooth progress of the drainage construction and the drainage effect, and also facilitating the removal of the drainage device from the water.

[0029] To improve the overall buoyancy of the drainage device in the water, several air tires that are not sleeved on the hanging cage can also be fixedly connected to the bottom surface of the bamboo raft. The several air tires that are not sleeved on the hanging cage are preferably evenly distributed on the bottom surface of the bamboo raft.

[0030] The structure of the utility model is simple and convenient for disassembly and assembly. During the drainage construction of water conservancy projects, it can effectively ensure the safety of the water pump, which not only helps the smooth progress of the drainage construction, but also can reduce the maintenance cost of the water pump and save labor input (when conducting drainage construction, the drainage device can be directly placed in the water).

[0031] All the preferred and optional technical means disclosed in the utility model, except as otherwise specified and except when one preferred or optional technical means is a further limitation of another technical means, can be arbitrarily combined to form several different technical solutions.
