Description

Technical Field

[0001] This utility model belongs to the field of water conservancy construction technology, and in particular relates to a drainage device for water conservancy construction. Background Technology

[0002] In the field of water conservancy construction, submersible pumps are one of the most commonly used drainage devices due to their compact structure, convenient installation, and high head. They are mainly used for drainage of sewage in some pools. In terms of installation convenience, submersible pumps have a significant advantage over traditional surface pumps. They do not require the construction of complex pump houses and save a lot of pipeline installation work. They can be put directly into the water to operate, which greatly saves construction time and costs and makes the preliminary preparation work for water conservancy construction more efficient.

[0003] Current drainage operations typically involve lowering submersible pumps directly into the water via ropes. This requires operators to assess the depth and position the pump at the bottom of the pool. However, in deep pools where the bottom condition is difficult to determine, direct placement of the pump can be problematic if it encounters debris or silt, hindering the drainage process. Therefore, a drainage device for hydraulic engineering is needed that can use a lifting mechanism to lower the submersible pump into the pool, thus adapting to deep-water drainage operations. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage device for water conservancy construction, which can send a submersible pump into a water pool through a lifting structure, thereby adapting to deep water pool drainage operations and solving the aforementioned background technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A drainage device for water conservancy construction includes a support frame and a fixed frame: a submersible pump is fixedly installed in the inner cavity of the support frame, a water outlet pipe is installed at the outlet of the submersible pump, an installation frame is fixedly installed on the surface of the fixed frame, a drum is rotatably connected to the inner wall of the installation frame, a large gear is fixedly connected to the surface of the drum, a connecting rod is rotatably connected to the inner wall of the installation frame, a small gear is sleeved and fixedly connected to the surface of the connecting rod, the small gear meshes with the large gear, a hand crank is fixedly installed at one end of the connecting rod, a steel wire rope is installed on the surface of the drum, a fixed pulley is rotatably connected to the surface of the fixed frame, and a hook is fixedly installed at one end of the steel wire rope.

[0006] Preferably, a fixing rod is fixedly connected to the inner wall of the mounting bracket, and a locking element is sleeved on the surface of the fixing rod.

[0007] Preferably, the locking member is rotatably connected to the fixing rod, and the locking member engages with the pinion.

[0008] Preferably, the surface of the support frame is rotatably connected to four wheels.

[0009] Preferably, the surface of the support frame is fixedly connected with a hanging ring, and the surface of the fixed frame is provided with four positioning holes.

[0010] The beneficial effects of this utility model are: 1. This utility model involves disengaging the fixed rod from the small gear, cranking the hand crank in the positive direction to make the small gear drive the large gear to rotate, which in turn drives the drum to rotate, causing the wire rope to unwind and the submersible pump to gradually descend into the water. Before it touches the bottom of the pool, the locking device is engaged, locking the device with the small gear to stop the submersible pump from descending. Then, the submersible pump begins to drain water. Once the submersible pump begins to emerge from the water, it continues to descend. This minimizes the risk of the submersible pump hitting the silt and debris at the bottom of the pool, thus achieving the purpose of adapting to deep pool drainage operations. 2. By incorporating wheels, this utility model allows the wheels on the support frame to rest against the pool wall when the deep pool wall is made of cement. This makes the descent of the submersible pump more stable, and when the submersible pump is lifted up, the wheels remain against the pool wall, making lifting the submersible pump less strenuous.

[0013] In the following description, embodiments of the drainage device for water conservancy construction according to the present invention will be described with reference to the accompanying drawings.

[0014] Figure 1-4This invention illustrates a drainage device for hydraulic construction according to an embodiment of the present invention, comprising a support frame 1 and a fixing frame 4. A submersible pump 2 is fixedly installed in the inner cavity of the support frame 1. A hanging ring is fixedly connected to the surface of the support frame 1. Four positioning holes are provided on the surface of the fixing frame 4. Four wheels 16 are rotatably connected to the surface of the support frame 1. By using the wheels 16, when the wall of the deep pool is a cement wall, the wheels 16 on the surface of the support frame 1 are brought into contact with the pool wall, making the descent of the submersible pump 2 more stable. When the submersible pump 2 is lifted, the wheels 16 are brought into contact with the pool wall, thus making lifting the submersible pump 2 easier. A water outlet pipe 3 is installed at the outlet of the submersible pump 2. A mounting bracket is fixedly installed on the surface of the fixing frame 4. Mounting frame 5, with a fixed rod 14 fixedly connected to the inner wall of mounting frame 5. A locking element 15 is fitted on the surface of the fixed rod 14 and is rotatably connected to the fixed rod 14. The locking element 15 engages with a small gear 9. A drum 6 is rotatably connected to the inner wall of mounting frame 5 and a large gear 7 is fixedly connected to the surface of the drum 6. A connecting rod 8 is rotatably connected to the inner wall of mounting frame 5 and a small gear 9 is fitted and fixedly connected to the surface of the connecting rod 8. The small gear 9 meshes with the large gear 7. A hand crank 10 is fixedly installed at one end of the connecting rod 8. A wire rope 11 is installed on the surface of the drum 6. A fixed pulley 12 is rotatably connected to the surface of the fixing frame 4 and a hook 13 is fixedly installed at one end of the wire rope 11.

[0015] Working Principle: When using this invention, the user first fixes the fixing frame 4 to the ground, hooks the hook 13 onto the hanging ring on the surface of the support frame 1, suspends the support frame 1 above the pool, and then moves the fixing rod 14 to disengage it from the small gear 9. At this time, the user cranks the hand crank 10 in the positive direction, causing the hand crank 10 to rotate the connecting rod 8, which in turn rotates the small gear 9 on its surface. Because the large gear 7 meshes with the small gear 9, the small gear 9 drives the large gear 7 to rotate, which in turn drives the drum 6 to rotate, causing the drum 6 to rotate on its surface. The wire rope 11 is unwound, causing the support frame 1 to descend via the fixed pulley 12, which in turn causes the submersible pump 2 to gradually fall into the water. Before it touches the bottom of the pool, the locking device 15 is engaged, locking the device 15 with the pinion 9, causing the submersible pump 2 to stop descending and then begin drainage operations. When the submersible pump 2 begins to emerge from the water, it continues to descend. This minimizes the risk of the submersible pump 2 hitting the silt and debris at the bottom of the pool, thus achieving the purpose of sending the submersible pump into the pool through the lifting structure, and adapting it to deep pool drainage operations.

[0016] In summary, this drainage device for hydraulic construction, by disengaging the fixed rod 14 from the pinion 9 and cranking the hand crank 10 in the positive direction, causes the pinion 9 to drive the large gear 7 to rotate, which in turn drives the drum 6 to rotate, causing the wire rope 11 to unwind and the submersible pump 2 to gradually descend into the water. Before it touches the bottom of the pool, the locking element 15 is engaged, locking the submersible pump 2 to stop descending. Then, the submersible pump 2 begins to drain water. Once the submersible pump 2 emerges from the water, it continues to descend. This minimizes the risk of the submersible pump 2 hitting the silt and debris at the bottom of the pool, thus achieving the purpose of adapting to drainage operations in deep pools.
