Description

Technical Field

[0001] This utility model relates to the field of water-stopping technology in water conservancy engineering construction, and in particular to a water-stopping structure for water conservancy engineering construction. Background Technology

[0002] In water conservancy projects, sluice gates are usually used to cut off the flow of water when stopping rivers. The connection between the sluice gate and the lifting device is usually made with bolts. However, under the erosion of river water, the bolts are prone to corrosion, which affects the disassembly and separation of the sluice gate and the lifting device.

[0003] Announcement No. CN217352348U describes a water-stopping structure for water conservancy engineering construction, comprising a frame, a gate, a fixing block, and a movable rod. The gate is located within the inner cavity of the frame, and the fixing block is located at the top of the gate. Through the coordinated use of the gate, fixing block, movable rod, receiving groove, positioning mechanism, and transmission mechanism, the transmission mechanism drives the positioning mechanism to move to a suitable position, then the movable rod is connected to the gate. Releasing the transmission mechanism allows the positioning mechanism to reset and fix the movable rod, thus completing the assembly of the gate. This solves the problem that existing gates typically require coordination with a lifting device on the frame, but the gate and lifting device are connected and fixed using threaded clamps, which consumes a lot of physical effort during assembly, and the exposed threaded connection is prone to rust; if the rust reaches a certain level, it will affect the disassembly of the gate.

[0004] The gate and the movable rod are connected by interlocking the positioning rod and the positioning groove. This avoids the problem of inconvenient disassembly caused by rusted threads. However, there will be gaps in the interlocking connection between the positioning rod and the positioning groove. In windy weather, the river water will strongly impact the gate, causing high-frequency hard collisions between the movable rod and the positioning rod. This can damage the positioning rod with the locking function, thus affecting the stability of the connection between the positioning rod and the movable rod. Utility Model Content

[0005] The purpose of this utility model is to provide a water-stopping structure for water conservancy engineering construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-stopping structure for water conservancy engineering construction, comprising:

[0007] Gate;

[0008] A hydraulic rod is installed at the top of the gate and is used to move the gate.

[0009] A connecting block is disposed on the opposite side of the gate and the hydraulic rod, and the connecting block is used to connect the gate and the output end of the hydraulic rod;

[0010] A locking assembly is disposed inside the connecting block and is used to connect the hydraulic rod output end and the connecting block.

[0011] A buffer element is disposed outside the locking assembly, and the buffer element is used to mitigate the impact between the hydraulic rod output end and the locking assembly.

[0012] Preferably, the output end of the hydraulic rod has a socket for inserting the locking component, one side of the connecting block has a slot for inserting the locking component, the bottom end of the connecting block is fixedly connected to the top end of the gate, the slot has a moving groove inside, and the water-facing surface of the connecting block has a water inlet.

[0013] Preferably, the locking component includes:

[0014] A locking rod is inserted into the slot and the hole, and one end of the locking rod has an annular groove.

[0015] A push spring is sleeved on the outer wall of the other end of the locking rod;

[0016] A fixed baffle is sleeved on the outer wall of the locking rod, and one side of the fixed baffle is fixedly connected to one end of the push spring.

[0017] Preferably, the buffer is disposed inside the annular groove.

[0018] Preferably, the buffer includes:

[0019] An expander, wherein the expander is disposed inside the annular groove;

[0020] A wrapping sleeve is fitted over the outside of the expansion material. The outer wall of the wrapping sleeve is fixedly connected to the inner wall of the annular groove, and a circular hole is provided on the outer wall of the wrapping sleeve.

[0021] Preferably, the gate is fitted with a gantry for gate movement, and the bottom end of the hydraulic rod is fixedly connected to an mounting plate for hydraulic rod installation, the bottom end of the mounting plate being fixedly connected to the top end of the gantry.

[0022] The technical effects and advantages of this utility model are as follows:

[0023] This invention utilizes a design of a hydraulic rod, connecting block, locking assembly, and buffer. In windy weather, river water flows into the connecting block through the inlet, causing the expansion material to absorb water and expand, filling the gap between the slot at the output end of the hydraulic rod and the locking rod. When the gate causes the connecting block to shake, the expanding material acts as a buffer against the impact force between the locking rod (which has a locking function) and the output end of the hydraulic rod, preventing direct hard collisions and protecting both the output end of the hydraulic rod and the locking rod, thus ensuring the stability of the connection between the gate and the hydraulic rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figure 1-6 The water-stopping structure shown in the figure includes:

[0033] Gate 1;

[0034] Hydraulic rod 2 is installed at the top of gate 1 and is used to drive the gate 1 to move.

[0035] Connecting block 3 is located on the opposite side of gate 1 and hydraulic rod 2. Connecting block 3 is used to connect the output ends of gate 1 and hydraulic rod 2.

[0036] Locking component 4 is located inside the connecting block 3 and is used to connect the output end of the hydraulic rod 2 and the connecting block 3.

[0037] The buffer 6 is disposed outside the locking assembly 4 and is used to reduce the impact between the output end of the hydraulic rod 2 and the locking assembly 4.

[0038] The output end of the hydraulic rod 2 is provided with a socket for inserting the locking component 4. One side of the connecting block 3 is provided with a slot for inserting the locking component 4. The bottom end of the connecting block 3 is fixedly connected to the top end of the gate 1. The slot is provided with a moving groove. The water-facing surface of the connecting block 3 is provided with a water inlet hole. The gate 1 is fitted with a gantry 5 for moving the gate 1. The bottom end of the hydraulic rod 2 is fixedly connected with an mounting plate 7 for installing the hydraulic rod 2. The bottom end of the mounting plate 7 is fixedly connected to the top end of the gantry 5.

[0039] Furthermore, the hydraulic rod 2 is an existing electro-hydraulic telescopic rod. The bottom end of the hydraulic rod 2 is fixedly connected to the connecting block 3 by bolts. The top of the gantry 5 and the mounting plate 7 are respectively provided with through slots for inserting the output end of the hydraulic rod 2. The insertion hole and the slot are the same size. The locking rod 41 is inserted into both the insertion hole and the slot to lock the connection between the output end of the hydraulic rod 2 and the connecting block 3. When the output end of the hydraulic rod 2 retracts, it drives the locking rod 41, which in turn drives the connecting block 3. The connecting block 3 drives the gate 1 to move vertically. The gantry 5 is used to restrict the gate 1 to move only vertically. The water inlet hole facilitates the entry of river water into the interior of the connecting block 3.

[0040] Locking component 4 includes:

[0041] A locking rod 41 is inserted into the slot and the hole, and one end of the locking rod 41 has an annular groove.

[0042] Push spring 42, which is sleeved on the outer wall of the other end of locking rod 41;

[0043] A fixed baffle 43 is sleeved on the outer wall of the locking rod 41, and one side of the fixed baffle 43 is fixedly connected to one end of the push spring 42.

[0044] Furthermore, both the push spring 42 and the fixed baffle 43 are disposed in the moving groove. The fixed baffle 43 is fixedly sleeved on the outer wall of the locking rod 41, and the push spring 42 is sleeved on the end of the locking rod 41 away from the annular groove. The push spring 42 is always in a compressed state in the moving groove.

[0045] The buffer 6 is located inside the annular groove.

[0046] Buffer 6 includes:

[0047] The expansion element 61 is disposed inside the annular groove;

[0048] The sleeve 62 is fitted over the outside of the expansion 61. The outer wall of the sleeve 62 is fixedly connected to the inner wall of the annular groove. The outer wall of the sleeve 62 has a circular hole.

[0049] Furthermore, the expander 61 is made of a material that expands upon contact with water and shrinks upon drying, such as cellulose-polyacrylamide composite hydrogel, which has good mechanical strength and elasticity. The sheath 62 is made of elastic rubber and forms a ring. The expander 61 fills the inside of the sheath 62. The outside of the sheath 62 has multiple small round holes, which facilitates the flow of water into the connecting block 3 into the interior of the sheath 62. After the expander 61 absorbs water and expands, it can buffer the hydraulic rod 2 output end and the locking rod 41 when they shake, thereby avoiding direct hard collision between the hydraulic rod 2 output end and the locking rod 41, preventing damage and breakage of the locking rod 41, and ensuring the stability of the connection between the connecting block 3 and the hydraulic rod 2 output end.
