Description

Technical Field

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

[0002] In the field of water conservancy construction, interception devices play a crucial role, affecting the progress and quality of the entire water conservancy project. Most existing interception devices are equipped with debris-blocking devices in front of them. However, in actual long-term use, these debris-blocking devices have gradually revealed serious problems. As the water flow continuously brings various debris, such as branches, aquatic plants, plastic waste, and silt, they gradually accumulate and adhere to the barrier netting, inevitably causing blockages over time.

[0003] When the retaining mesh becomes clogged, it significantly reduces the efficiency of water flow, leading to a greater water level difference between the upstream and downstream of the intercepting device. This further increases water pressure and instability in the construction area, and may even affect the structural stability of the entire intercepting device. More problematic is the numerous drawbacks of current methods for handling such blockages. Existing systems often require workers to personally descend into the intercepting channel to clear the retaining mesh. This poses significant safety hazards, such as workers being swept away by the current, slipping and getting injured, or being injured by sharp objects hidden in the debris. Moreover, this cleaning method is inefficient, consuming substantial manpower and time, severely impacting the overall progress and efficiency of water conservancy construction. Utility Model Content

[0004] The purpose of this utility model is to provide a diversion device for water conservancy construction to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution, which includes a water passage, a guide gate frame at the tail of the water passage, a gate movably disposed within the guide gate frame, a first telescopic cylinder at the top of the guide gate frame, the telescopic rod of the first telescopic cylinder being connected to the top of the gate, an easy-to-clean debris filter assembly disposed within the water passage, and positioning components symmetrically disposed on both sides of the water passage.

[0006] As a preferred embodiment of this utility model, the easy-to-clean debris filter assembly includes a rotating shaft, which is movably mounted between two side plates of the water passage via a pair of bearing seats. Several debris baffles are provided on the rotating shaft, and a debris-collecting shovel is provided at the bottom of each debris baffle. Positioning holes are symmetrically opened on both sides of the debris-collecting shovel. A transmission gear one is provided at one end of the rotating shaft, and the transmission gear one and transmission gear two are meshed and connected. The transmission gear two is located on the transmission end of the motor.

[0007] As a preferred embodiment of this utility model, an mounting plate is provided on one outer wall of the water passage, and the motor is mounted on the mounting plate.

[0008] As a preferred embodiment of this utility model, the positioning component includes a second telescopic cylinder, the top of the telescopic rod of the second telescopic cylinder is provided with a fixing plate, the fixing plate is connected to the push-pull plate by a pair of bolts, and the front of the push-pull plate is provided with a positioning rod corresponding to the positioning hole.

[0009] As a preferred embodiment of this utility model, mounting brackets are symmetrically arranged on both sides of the water passage, and the two second telescopic cylinders are respectively mounted on the two mounting brackets.

[0010] As a preferred embodiment of this utility model, a sealing sleeve is provided on the positioning rod.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] 1. When it is necessary to clean up debris, the present invention uses a motor to drive the transmission gear set to rotate the rotating shaft, thereby rotating the debris baffle to a position that is easy to clean. The debris shovel can scoop up the debris, eliminating the need for workers to enter the dangerous interception channel for manual cleaning. This greatly improves the cleaning efficiency, reduces the cleaning difficulty and risk, and ensures the normal operation and long-term stability of water conservancy facilities.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] like Figures 1-5 As shown, the present invention proposes a water diversion device for water conservancy construction, which mainly includes a water passage 1. The water passage 1 is provided with a guide gate frame 10 at the tail end. The gate 11 inside the gate frame is connected to the telescopic rod of the first telescopic cylinder 12 at the top of the gate frame. The first telescopic cylinder 12 extends and retracts to drive the gate 11 to move inside the gate frame, thereby controlling the water flow to be cut off or released.

[0022] The water passage 1 is equipped with an easy-to-clean debris filter assembly 2. Its rotating shaft 20 is installed between the two side plates of the water passage 1 via a bearing seat 21. There are several debris baffles 22 on the shaft. There is a debris-collecting shovel 23 at the bottom of the baffle. The debris-collecting shovel 23 has positioning holes 27 on both sides. The transmission gear 24 at one end of the rotating shaft 20 meshes with the transmission gear 26 at the transmission end of the motor 25. The motor 25 is placed on the mounting plate 4 on the outer wall of one side of the water passage 1. When the motor 25 is started, it can drive the rotating shaft 20 to rotate, thereby changing the position of the debris baffles 22.

[0023] Regarding the positioning component 3, the fixed plate 31 at the top of the telescopic rod of the second telescopic cylinder 30 is connected to the push-pull plate 33 by bolts 32. The positioning rod 34 on the front of the push-pull plate 33 is set to correspond to the positioning hole 27 of the shovel 23. The mounting brackets 5 on both sides of the water passage 1 are respectively equipped with the second telescopic cylinder 30. By telescopically extending and retracting, the positioning rod 34 moves in and out of the positioning hole 27 to fix or release the position of the debris baffle 22. The positioning rod 34 is fitted with a sealing sleeve 6 to prevent water flow from eroding the components, ensuring the stable operation of the structure, and facilitating the cleaning of debris and the normal operation of water conservancy facilities.

[0024] When it is necessary to cut off the flow, simply activate the first telescopic cylinder 12 to lower the gate 11 to cut off the flow.

[0025] Under normal water flow conditions, i.e., without interception, the debris barrier 22 can effectively block various debris in the water, preventing the debris from spreading further with the water flow. When it is necessary to clean up the debris intercepted by the debris barrier 22, the operation procedure is as follows: First, control the two second telescopic cylinders 30 to retract their telescopic rods simultaneously. This action will drive the connected push-pull plate 33 to move synchronously, thereby causing the push-pull plate 33 to smoothly move the positioning rod 34 that was originally inserted into the positioning hole 27 of the shovel 23. After completing this step, the motor 25 is started. The power generated by the motor 25 drives the transmission gear 26 to rotate. Since the transmission gear 26 is tightly meshed with the transmission gear 24, this meshing transmission action will drive the rotating shaft 20 to rotate precisely 90 degrees clockwise. At this time, the debris barrier 22, which was originally blocking the water passage 1 to perform the interception task, is removed. 2 will rotate to a position parallel to the top of the side plates of the water passage 1. At the same time, the shovel 23 will scoop up and support the debris blocked and accumulated at the front of the debris baffle 22. During the rotation of the rotating shaft 20, the debris baffle 22 on the rear side will rotate into the water passage 1 accordingly, filling the empty space after the front debris baffle 22 is moved away, ensuring that the water flow will not be greatly affected by the cleaning operation. When the positioning holes 27 on both sides of the rear shovel 23 are correctly aligned with the positioning components 3, the two positioning components 3 will restart the second telescopic cylinder 30, so that the two positioning rods 34 are inserted back into the positioning holes 27, thereby stabilizing the rear debris baffle 22 and the shovel 23 in the working position. After the two positioning components 3 have completed the positioning operation, the operator can safely and efficiently clean the debris on the previous debris baffle 22.
