Description

Technical Field

[0001] The utility model relates to the technical field of dam devices, in particular to an anti-scouring hydraulic dam with a river sluice structure. Background Art

[0002] In order to mitigate the impact of waves on the dam, some companies install a base on the water-facing side of the dam, with an elastic sliding connection to a fixed plate on the base, and a baffle installed on the fixed plate. The waves impact the baffle, causing the fixed plate to slide along the base, which is buffered by the elastic structure to help mitigate the impact. In order to adjust the scheduling of the baffle, some companies add a bevel gear transmission mechanism to the fixed plate, and change the angle of the baffle through the bevel gear transmission. Due to the existence of gear meshing in this structure, the subsequent maintenance is more troublesome, and inadequate maintenance may easily affect the operation, which needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0004] The present application document discloses a river channel sluice structure anti-scour water conservancy dam, including a dam body, a base, a fixed plate, and a baffle. The base is arranged at the water-facing surface of the dam body, the base is elastically slidably connected to the fixed plate, the baffle is hinged on the fixed plate, the fixed plate is slidably connected to a sliding rod, a locking mechanism is arranged on the sliding rod, and the sliding rod is locked in a predetermined position by the locking mechanism. The sliding rod is connected to the end of the baffle by a connecting rod. When the sliding rod moves, the angle of the baffle relative to the fixed plate changes under the transmission of the connecting rod.

[0005] In this scheme, the structure of the dam is improved, and the angle of the baffle is adjusted by a sliding rod in cooperation with a connecting rod, and the position of the sliding rod is fixed by a locking mechanism. This structure has no gear meshing structure, which helps to improve the stability of operation and is simple for later maintenance.

The slide groove is added to facilitate the installation of the slide rod, and the connecting rod is hinged to facilitate the adjustment of the angle of the baffle.

[0007] Furthermore, the locking mechanism includes a sliding seat and a plug. The sliding seat is slidably connected to the side of the fixed plate along the length direction of the slide groove. The plug is slidably connected to the sliding seat. Through holes are arranged at intervals along the length direction on the sliding rod. A number of locking grooves are correspondingly arranged on the groove wall of the slide groove. The plug is moved through the through holes and inserted into the locking groove. The locking mechanism has a simple structure. The sliding rod can be moved by pulling the plug out of the locking groove, thereby adjusting the baffle to the desired angle. After that, the plug can be pressed inward to insert it into the locking groove, so that the sliding rod is fixed and the baffle is fixed at the desired angle.

[0008] Furthermore, a mark is set on the fixed plate corresponding to the side of the sliding rod, and the mark corresponds to the locking groove one by one, so that after moving the sliding rod to the desired position, the insertion column is moved to insert it into the locking groove.

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Example 1

[0019] like Figure 1 , Figure 2As shown, in this example, the anti-scouring water conservancy dam of the river sluice structure includes a dam body 1, a base 2, a fixed plate 3, and a baffle 4. The base 2 is installed at the water-facing surface of the dam body 1. The base 2 includes an end plate 21, a guide column 22, and a mounting seat 23. The two end plates 21 are connected by a guide column 22. For example, one end plate 21 is fixed to the upper part of the water-facing surface, and the other end plate 21 is fixed to the lower part of the water-facing surface. The guide column 22 is fixed between the upper and lower end plates 21. If the mounting seat 23 is formed with a hole, the guide column 22 passes through the hole and slides, and the mounting seat 23 slides along the guide column 22. In this example, a spring 24 is sleeved on the guide column 22 above the mounting seat 23. The head end of the spring 24 is fixed to the guide column 22 and the tail end is fixed to the mounting seat 23, so that the spring provides buffering.

[0020] A fixing plate 3 is installed on the top surface of the mounting seat 23. The fixing plate 3 is parallel to the water-facing surface. The fixing plate is a common frame type. A plurality of baffles 4 are installed in the frame opening of the fixing plate 3. The baffles 4 are arc-shaped and have a plurality of through holes formed on the baffles. Both ends of the baffles 4 are hinged with the corresponding side frames through shafts, etc.

[0021] A slide rod 5 is slidably installed on one side of the fixed plate 3. The slide rod 5 is connected to the end of the baffle 4 by a connecting rod 9. The inclination angle of the baffle can be adjusted by moving the slide rod, and a locking mechanism is added to fix the slide rod.

[0022] like Figure 1 , Figure 2 As shown, a slide groove is formed on the side of the frame of the fixed plate 3, and the slide rod partially extends into the slide groove and slides together. A hole is formed on the frame below the hinged position of the baffle 4, and the hole is connected to the slide groove. The end of the baffle 4 below the hinged position is hinged to the head end of the connecting rod 9, and the tail end of the connecting rod 9 is hinged to the slide rod in the slide groove through the hole. The slide rod is moved back and forth, and the baffle is rotated relative to the fixed plate under the action of the connecting rod to achieve angle adjustment.

[0023] like Figure 1 , Figure 2 As shown, a locking mechanism is added in this example, and the locking mechanism includes a slide 6 and a column 7. The slide 6 is installed on the side frame surface of the fixed plate 3. The slide 6 is slidably connected to the fixed plate 3 in the length direction of the slide groove. The column 7 is installed on the slide 6. A through hole is formed on the slide 6 along the length direction of the baffle 4. The head end of the column 7 is outside the slide and the bottom end of the column 7 passes through the through hole. A through hole is formed on the slide rod and the end of the column extends into the through hole to make the slide and the slide rod move synchronously, and grooves are formed at intervals along the length direction at the bottom wall of the slide groove, namely, locking grooves 10. The column is moved so that its bottom end is inserted into the locking groove, and the movement of the slide rod is locked. When the column is moved outward to make its bottom end disengage from the locking groove, the slide seat moves the slide rod synchronously.

[0024] like Figure 1As shown, in this example, a mark 8 is added to the fixed plate 3, such as by painting a color at a predetermined position to form a mark, and the mark corresponds to the position of the lock groove one by one. In this example, a through hole is directly formed on the fixed plate, and the through hole is used as the mark 8, which facilitates moving the sliding rod to the predetermined position, and then makes the baffle at a predetermined angle.

[0025] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
