Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a river diversion and interception device. Background Technology

[0002] Water conservancy projects are engineering projects built to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering projects. In the process of river water conservancy construction, the method of interception is often used to block the water flow so that it no longer flows to the construction site, thus providing a guarantee for river water conservancy construction.

[0003] A search revealed that patent document CN223151116U discloses a river diversion and interception device, including a support base with two symmetrically arranged receiving slots on both sides of the upper end of the support base. Each receiving slot contains a diversion gate. Through the design of the electro-hydraulic rod, diversion gate, diversion channel, filter cover, and diversion pipe, this river diversion and interception device, after intercepting and blocking the river, can use the diversion channel and diversion pipe to drain the water accumulated upstream of the river through external pipes, bypassing the water conservancy construction site on the river. This effectively avoids excessive accumulation of water upstream after the blockage, preventing the river from overflowing and causing flooding. Simultaneously, by installing a filter screen on each side of the interception slot, the device effectively prevents debris from entering the space below the interception gate during river interception and blockage.

[0004] However, while the device intercepts debris in the river channel through the filter screen, it cannot remove garbage. This causes a large amount of debris to accumulate near the filter screen when the device is used to block the river, resulting in blockage and affecting subsequent sluice gate opening and water release. Therefore, a river diversion and interception device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a river diversion and interception device that has advantages such as easy removal of debris. It solves the problem that existing river diversion and interception devices intercept debris in the river through a filter screen, but cannot remove garbage, resulting in a large amount of debris accumulating near the filter screen and causing blockage when the device is used to intercept and block the river, thus affecting the subsequent opening of the gate for water release.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a river diversion and interception device, comprising a dam body, wherein an interception mechanism is provided on the dam body;

[0007] The interception mechanism includes a support frame fixedly connected to the upper side of the dam body, a hydraulic rod fixedly installed on the upper side of the support frame, a gate plate extending to the inner side of the dam body fixedly installed on the output shaft of the hydraulic rod, and a retrieval mechanism provided on the outer side of the gate plate.

[0008] The salvage mechanism includes a fixed plate fixedly connected to the upper side of the support frame. A protective box is fixedly installed on the top of the fixed plate. A winch is installed inside the protective box. A drive motor is connected to the input end of the winch. A traction rope is provided at the rotating end of the winch. The connecting end of the traction rope passes through the fixed plate and extends to the inside of the dam body. A net plate is connected to the connecting end of the traction rope.

[0009] Furthermore, an overflow box is provided on the side of the top of the gate away from the retrieval mechanism. The overflow box is fixedly installed on the inner side of the dam body, and an overflow outlet is provided on the side of the overflow box near the gate.

[0010] Furthermore, both sides of the overflow box are fixedly connected to guide pipes, with the end of the guide pipe away from the overflow box penetrating and extending to the outside of the dam body.

[0011] Furthermore, two first guide rods are fixedly connected to the top of the gate, and the upper ends of the two first guide rods extend to the upper side of the support frame, with the outer wall of the first guide rod slidingly engaged with the support frame.

[0012] Furthermore, a connecting frame is provided on the upper side of the mesh plate, and the connecting end of the traction rope is connected to the top of the connecting frame.

[0013] Furthermore, a counterweight frame is fixedly connected to the bottom of the connecting frame, and the mesh plate is fixedly installed on the inner side of the counterweight frame.

[0014] Furthermore, two second guide rods are fixedly installed on the top of the connecting frame, and the upper ends of the two second guide rods extend to the upper side of the fixing plate, with the outer wall of the second guide rods slidingly engaged with the fixing plate.

[0015] Compared with the prior art, this utility model provides a river diversion and interception device, which has the following beneficial effects:

[0016] 1. The diversion and interception device for this river channel, when a large amount of debris accumulates near the gate, activates the drive motor to drive the winch, which in turn moves the traction rope, causing the connecting frame to move upward. The connecting frame then moves the counterweight frame and the screen plate upward simultaneously. The screen plate is used to scoop up the debris accumulated near the gate. Subsequently, the staff can transfer the debris on the screen plate, facilitating the cleaning of the debris. This solves the problem in the existing technology where the diversion and interception device for the river channel intercepts debris in the river through the filter screen plate, but cannot scoop up garbage. As a result, when the device is used to intercept and block the river channel, a large amount of debris accumulates near the filter screen plate, causing blockage and affecting the subsequent opening of the gate for water release.

[0017] 2. The diversion and interception device of the river channel allows water exceeding the height of the gate to flow into the overflow box when the gate is blocking the river. The diversion pipe can be connected to valves and external pipes to facilitate the transfer of excess water. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1 to 4In this embodiment, a river diversion and interception device includes a dam body 1, on which an interception mechanism is provided.

[0025] Two first guide rods 16 are fixedly connected to the top of the gate plate 4. The upper ends of the two first guide rods 16 extend to the upper side of the support frame 2. The outer wall of the first guide rod 16 slides with the support frame 2, which plays a guiding role.

[0026] In this embodiment, a retrieval mechanism is provided on the outer side of the gate 4. The retrieval mechanism includes a fixed plate 5 fixedly connected to the upper side of the support frame 2. A protective box 6 is fixedly installed on the top of the fixed plate 5. A winch 7 is installed inside the protective box 6. A drive motor 8 is connected to the input end of the winch 7. A traction rope 9 is provided on the rotating end of the winch 7. The connecting end of the traction rope 9 passes through the fixed plate 5 and extends to the inner side of the dam body 1. A net plate 12 is connected to the connecting end of the traction rope 9. A connecting frame 10 is provided on the upper side of the net plate 12. The connecting end of the traction rope 9 is connected to the top of the connecting frame 10. A counterweight frame 11 is fixedly connected to the bottom of the connecting frame 10. The net plate 12 is fixedly installed on the inner side of the counterweight frame 11. The setting of the counterweight frame 11 facilitates the sinking of the net plate 12 to the bottom of the river. When the counterweight frame 11 and the net plate 12 move upward, they can retrieve the debris gathered near the gate 4. The setting of the net plate 12 facilitates the drainage of water when it rises.

[0027] Two second guide rods 17 are fixedly installed on the top of the connecting frame 10. The upper ends of the two second guide rods 17 extend to the upper side of the fixing plate 5. The outer wall of the second guide rod 17 slides with the fixing plate 5, which plays a guiding role.

[0028] In this embodiment, an overflow box 13 is provided on the side of the top of the gate 4 away from the retrieval mechanism. The overflow box 13 is fixedly installed inside the dam body 1. An overflow outlet 14 is provided on the side of the overflow box 13 near the gate 4. Both sides of the overflow box 13 are fixedly connected to guide pipes 15. The end of the guide pipe 15 away from the overflow box 13 passes through and extends to the outside of the dam body 1. When the gate 4 is blocking the river channel, the water flow exceeding the height of the gate 4 can flow into the overflow box 13. The guide pipe 15 can be connected to valves and external pipes to transfer excess water flow.

[0029] The working principle of the above embodiments is as follows:

[0030] In use, the hydraulic rod 3 is activated to move the gate 4 downward to the inside of the dam body 1, so that the gate 4 can block the river. When a large amount of debris accumulates near the gate 4, the drive motor 8 is activated to drive the winch 7 to operate, and the traction rope 9 moves, which drives the connecting frame 10 to move upward. The connecting frame 10 will then drive the counterweight frame 11 and the net plate 12 to move upward synchronously. The net plate 12 is used to retrieve the debris accumulated near the gate 4. Then, the staff can transfer the debris on the net plate 12.
