Description

Technical Field

[0001] This utility model relates to the field of dam drainage technology, and in particular to a dam drainage device for a sand-blocking dam. Background Technology

[0002] In soil and water conservation projects, silt-trapping dams are important facilities used to intercept sediment, reduce water flow velocity, and reduce soil erosion. In order to divert water from the dam body to the dam toe or downstream drainage gallery, effectively lower the phreatic line, and improve the stability of the dam body, vertical or inclined drainage pipes need to be installed in the dam body. It is an important device to ensure the safety and stability of the dam body.

[0003] Since silt-trapping dams typically have a large area, a single drainage pipe cannot meet the drainage needs. Therefore, multiple drainage pipes are connected together by welding to form a drainage network covering the entire dam body. However, because the connection points of the drainage pipes are directly exposed to the external environment, they are easily corroded by dust, silt, and debris. In humid environments, these impurities adhere to the surface of the connection points and rust. The rust gradually corrodes the weld points, reducing the sealing performance of the connection and causing leakage in the drainage pipes, thus affecting the drainage effect of the dam body. To address these issues, we propose a silt-trapping dam body drainage device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drainage device for a sand-blocking dam.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drainage device for a sand-blocking dam includes drainage pipes. Two sets of drainage pipes are provided, with a connecting end connected to one end of each set of drainage pipes. Fixing rings are inserted into the outer sides of each set of drainage pipes, and connecting rods are connected to the sides of each fixing ring. Connecting rings are sleeved on the outer sides of each drainage pipe, and cavities adapted to the connecting rods are opened inside the connecting rings. Limiting rods are inserted into the connecting rods, and limiting blocks are connected to the ends of the limiting rods. Two sets of slots adapted to the limiting blocks are opened inside the connecting rods.

[0007] Preferably, the end of the connecting rod away from the fixed ring is connected to a sliding block, and the inside of the connecting ring is provided with a sliding groove that matches the sliding block.

[0008] Preferably, one set of the connecting rings has a rubber ring connected to its end, and the other set of the rubber rings has an annular groove adapted to the rubber ring at its end.

[0009] Preferably, L-shaped rods are uniformly welded to the outer side of the connecting ring, and the ends of the L-shaped rods are all connected to rotating rods through bearings.

[0010] Preferably, the outer side of the rotating rod is fitted with a rubber sleeve, and the rubber sleeve is made of rubber.

[0011] Preferably, the two sets of fixing rings are respectively connected to mounting rings on the sides that are far apart from each other, and the interior of the mounting rings is connected to the outer wall of the drain pipe by bolts.

[0012] Preferably, the side of the fixing ring is connected to two sets of connecting rods, and the two sets of connecting rods are symmetrically distributed about the central axis of the fixing ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This device is equipped with a connecting ring and a connecting rod. During use, the connecting rod and the connecting ring work together to surround and protect the welded connection ends, thereby effectively preventing dust, mud, and debris from the external environment from corroding the connection parts and ensuring the safety of the connection parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A drainage device for a sand-blocking dam includes a drainage pipe 1, which is provided in two sets. The ends of the two sets of drainage pipes 1 that are close to each other are connected to a connecting end 2. A fixing ring 3 is inserted into the outer side of each set of drainage pipes 1, and a connecting rod 4 is connected to the side of each fixing ring 3. A connecting ring 5 is sleeved on the outer side of each drainage pipe 1, and a cavity 6 adapted to the connecting rod 4 is opened inside the connecting ring 5. A limiting rod 7 is inserted into the connecting rod 4, and a limiting block 8 is connected to the end of the limiting rod 7. Two sets of slots adapted to the limiting block 8 are opened inside the connecting rod 4. Since the outer diameter of the connecting end 2 is smaller than the inner diameter of the connecting ring 5, the protruding welding point can be completely surrounded, and the protection effect of the connecting ring 5 on the welding point of the connecting end 2 can be effectively guaranteed. In addition, the inner wall of the connecting ring 5 and the outer wall of the drainage pipe 1 are tightly fitted, thereby further ensuring the sealing effect of the connecting ring 5 on the connecting end 2.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the end of the connecting rod 4 away from the fixed ring 3 is connected to a sliding block 11. The inside of the connecting ring 5 is provided with a sliding groove that matches the sliding block 11. During use, the sliding block 11 and the sliding groove cooperate to guide the connecting rod 4 laterally, thereby ensuring the stable lateral movement of the connecting rod 4. Furthermore, the sliding block 11 and the sliding groove effectively prevent the connecting rod 4 from being completely pulled out of the cavity 6.

[0025] Furthermore, refer to Figure 3 and Figure 5 It can be seen that one set of connecting rings 5 ​​has a rubber ring 9 connected to its end, and the other set of rubber rings 9 has an annular groove that matches the rubber ring 9 at its end. During use, the gap between the two sets of connecting rings 5 ​​can be filled by the cooperation between the rubber ring 9 and the annular groove, thereby effectively improving the sealing effect of the weld point on the outer periphery of the connecting end 2.

[0026] Furthermore, refer to Figure 2 and Figure 5It can be seen that L-shaped rods 12 are uniformly welded on the outer side of the connecting ring 5, and the ends of the L-shaped rods 12 are all connected to rotating rods 13 through bearings. In use, the cooperation of each set of L-shaped rods 12 and rotating rods 13 can protect the outer periphery of the connecting ring 5 and the connecting end 2, thereby preventing external forces from directly impacting the connecting part of the device, so as to ensure the reliability of the connection between the connecting ends 2. Furthermore, since the L-shaped rods 12 and rotating rods 13 are connected through bearings, sliding friction can be converted into rolling friction, which can further buffer external forces.

[0027] Furthermore, refer to Figure 5 It can be seen that the outer side of the rotating rod 13 is fitted with a rubber sleeve 14, and the rubber sleeve 14 is made of rubber. During use, the rubber sleeve 14 made of rubber can buffer external forces, thereby achieving further buffering of external forces.

[0028] Furthermore, refer to Figure 3 It can be seen that the two sets of fixing rings 3 are respectively connected to the mounting rings 10 on the side that is far apart from each other, and the inside of the mounting rings 10 is connected to the outer wall of the drainage pipe 1 by bolts. During use, by the cooperation of the mounting rings 10 and the bolts, when the connecting end 2 is removed from the dam body for replacement, it is convenient for the staff to remove the fixing rings 3 from the outside of the drainage pipe 1 for reuse.

[0029] Furthermore, refer to Figure 2 It can be seen that there are two sets of connecting rods 4 connected to the side of the fixed ring 3, and the two sets of connecting rods 4 are symmetrically distributed about the central axis of the fixed ring 3. During use, the two sets of connecting rods 4 connected to the side of the fixed ring 3, as well as the two sets of cavities 6 opened inside the connecting ring 5, can effectively ensure the tightness of the connecting ring 5 when it slides laterally.

[0030] Working Principle: In use, the operator first brings the drain pipes 1 that need to be connected close together, ensuring the two sets of connecting ends 2 of the drain pipes 1 abut against each other. Then, the operator uses appropriate tools to weld the connecting ends 2 together. After welding, the operator pulls the limiting block 8 to remove the limiting rod 7 from the inside of the connecting rod 4 and the connecting ring 5, thus releasing the limiting effect on the connecting ring 5. The operator can then slide the connecting ring 5 laterally, allowing it to slide along the inner wall of the connecting rod 4 under force. Through the cooperation of the sliding block 11 and the slide rail, when the connecting ring 5 can no longer slide, the pre-reserved groove inside the connecting ring 5, which matches the limiting rod 7, aligns with another set of slots inside the connecting rod 4. The operator can insert the limiting rod 7 into the reserved groove of the connecting rod 4 again, and extend it into another set of slots inside the connecting rod 4, thereby limiting the pulled-out connecting ring 5. Then the operator can repeat the above steps to pull out the connecting ring 5 set on the outside of the other set of drain pipe 1. At this time, the rubber ring 9 connected to the end of one set of connecting ring 5 can be inserted into the annular groove opened inside the other set of connecting ring 5. The rubber ring 9, made of rubber material, can fill the annular groove. Through the cooperation of the two, the sealing of the connecting ring 5 when it covers the outside of the connecting end 2 can be effectively guaranteed. The two sets of connecting rings 5 ​​surrounding the connecting part of the connecting end 2 can protect the connecting part of the connecting end 2. The above is the entire working principle of this utility model.
