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 construction of water conservancy projects, interception is a crucial step, the purpose of which is to cut off the water flow and create dry conditions for subsequent construction.

[0003] Currently, existing water conservancy construction interception devices often lack interception nets to intercept garbage. During the interception process, garbage such as tree branches, plastic bags, and floating objects in the river will flow with the water. Due to the lack of effective interception nets, the garbage cannot be centrally processed and will be scattered everywhere with the water flow, polluting downstream waters, affecting the river's ecological environment, and even threatening the safety of drinking water for nearby residents. In addition, the scattered garbage is difficult and costly to clean up, requiring a large investment of manpower and resources for dredging and cleaning, further increasing the overall cost of water conservancy projects. Therefore, improvements are needed. Utility Model Content

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

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a diversion device for water conservancy construction, comprising a base frame, side plates, and a frame. An interception net is fixedly installed inside the frame, and a top plate is fixedly installed on the top of the frame. A limiting hole is symmetrically opened through one side of the top plate. A fixing plate is fixedly installed on the top of the base frame. A limiting rod is symmetrically slidably connected inside the fixing plate. A baffle is fixedly installed on the outer wall of the limiting rod. A handle is fixedly installed at one end of the limiting rod. A return spring is sleeved on the outer wall of the limiting rod. Positioning blocks are symmetrically fixedly installed on the top of the side plates, and positioning grooves are symmetrically opened at the bottom of the frame.

[0006] Preferably, the positioning groove and the positioning block are slidably connected.

[0007] Preferably, the side plate is located on the bottom side of the base frame, and the side plate is fixedly connected to the base frame.

[0008] Preferably, the limiting rod and the limiting hole are slidably connected.

[0009] Preferably, one end of the reset spring is fixedly connected to the baffle, and the other end of the reset spring is fixedly connected to the fixing plate.

[0010] Preferably, a connecting handle is fixedly installed on the top of the top plate.

[0011] Preferably, the bottom of the base frame is uniformly fixed with inserts.

[0012] Preferably, a protective shell is fixedly installed on one side of the base frame.

[0013] Preferably, a rotating shaft is uniformly rotatably connected inside the base frame, a flow-blocking plate is fixedly installed on the outer wall of the rotating shaft, a worm gear is fixedly installed at the top of the rotating shaft, a drive motor is fixedly installed on one side of the base frame, and a worm is fixedly installed at the output end of the drive motor.

[0014] Preferably, there are three sets of the rotating shaft, the baffle plate, and the worm gear, and the three sets of worm gears mesh with the worm.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting up an interception net inside the frame, floating objects such as tree branches and plastic bags can be physically intercepted when water flows through, concentrating the garbage in front of the frame and effectively preventing it from spreading downstream. This not only protects the river's ecological environment and eliminates the threat to the safety of drinking water for surrounding residents, but also makes garbage collection and cleaning more convenient. At the same time, to address the cleaning difficulties, a quick-disassembly structure is designed. Pulling the handle causes the limiting rod to disengage from the limiting hole, and the frame can be disassembled and the interception net can be cleaned using the positioning groove and positioning block. After cleaning, it can be quickly reset, greatly reducing the difficulty and cost of cleaning, effectively solving the shortcomings of existing devices, and optimizing the water conservancy project interception operation process.

[0017] 2. In this utility model, after the drive motor on one side of the base frame starts, the worm at its output end meshes with three sets of worm wheels, driving the worm wheels fixed at the top of the rotating shaft to rotate, thereby causing the rotating shaft to rotate. The intercepting plate connected to the outer wall of the rotating shaft will rotate together with the rotating shaft. By controlling the direction and rotation angle of the drive motor, the tilt angle of the three sets of intercepting plates can be adjusted synchronously. When the three sets of intercepting plates are closed synchronously, their large-area plate surface blocks the water flow, achieving interception. When the three sets of intercepting plates are opened synchronously, the water flow can pass through the gap between the plates, allowing flow regulation. The three sets of rotating shafts, intercepting plates and worm wheels are linked by the worm to ensure synchronous rotation, avoiding water leakage due to lag in the action of a single component or angular deviation, thereby improving the stability and reliability of the interception process.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a diversion device for water conservancy construction, including a base frame 1, side plates 2, and a frame 3. An interception net 4 is fixedly installed inside the frame 3, and a top plate 5 is fixedly installed on the top of the frame 3. A limiting hole 6 is symmetrically opened through one side of the top plate 5. A fixing plate 7 is fixedly installed on the top of the base frame 1. A limiting rod 8 is symmetrically slidably connected inside the fixing plate 7. A baffle 9 is fixedly installed on the outer wall of the limiting rod 8. A pull handle 10 is fixedly installed at one end of the limiting rod 8, and a return spring 11 is sleeved on the outer wall of the limiting rod 8. The top of the side plate 2... The frame 3 is fixedly installed with positioning blocks 12. The bottom of the frame 3 is symmetrically provided with positioning grooves 13. The positioning grooves 13 and positioning blocks 12 are slidably connected. The side plate 2 is located on one side of the bottom of the base frame 1. The side plate 2 is fixedly connected to the base frame 1. The limiting rod 8 is slidably connected to the limiting hole 6. One end of the reset spring 11 is fixedly connected to the baffle 9. The other end of the reset spring 11 is fixedly connected to the fixing plate 7. The top plate 5 is fixedly installed with a connecting handle 21. The bottom of the base frame 1 is evenly fixedly installed with inserts 20. The base frame 1 is fixedly installed with a protective shell 19 on one side.

[0027] In this embodiment, by setting up an interception net 4 inside the frame 3, floating objects such as tree branches and plastic bags can be physically intercepted when the water flows through, concentrating the garbage in front of the frame 3 and effectively preventing it from spreading downstream. This not only protects the river's ecological environment and eliminates the threat to the safety of drinking water for surrounding residents, but also makes garbage collection and cleaning more convenient. At the same time, to address the cleaning difficulties, a quick-disassembly structure is designed. Pulling the handle 10 causes the limiting rod 8 to disengage from the limiting hole 6, and the frame 3 can be disassembled and the interception net 4 can be cleaned using the positioning groove 13 and the positioning block 12. After cleaning, it can be quickly reset, greatly reducing the cleaning difficulty and cost, effectively solving the shortcomings of existing devices, and optimizing the water conservancy project interception operation process.

[0028] Example 2: As Figure 5 As shown, a rotating shaft 14 is uniformly rotatably connected inside the base frame 1. A flow-blocking plate 15 is fixedly installed on the outer wall of the rotating shaft 14. A worm gear 16 is fixedly installed at the top of the rotating shaft 14. A drive motor 17 is fixedly installed on one side of the base frame 1. A worm 18 is fixedly installed at the output end of the drive motor 17. There are three sets of rotating shaft 14, flow-blocking plate 15 and worm gear 16. The three sets of worm gear 16 mesh with the worm 18.

[0029] In this embodiment, after the drive motor 17 on one side of the base frame 1 starts, the worm 18 at its output end meshes with three sets of worm wheels 16, driving the worm wheels 16 fixed at the top of the rotating shaft 14 to rotate, thereby causing the rotating shaft 14 to rotate. The flow intercepting plate 15 connected to the outer wall of the rotating shaft 14 will rotate together with the rotating shaft 14. By controlling the direction and rotation angle of the drive motor 17, the tilt angle of the three sets of flow intercepting plates 15 can be adjusted synchronously. When the three sets of flow intercepting plates 15 are closed synchronously, their large-area plate surface blocks the water flow, achieving flow interception. When the three sets of flow intercepting plates 15 are opened synchronously, the water flow can pass through the gap between the plates, allowing flow regulation. The three sets of rotating shafts 14, flow intercepting plates 15 and worm wheels 16 are linked by the worm 18 to ensure synchronous rotation, avoiding water leakage due to lag in the action of a single component or angular deviation, thereby improving the stability and reliability of the flow interception process.

[0030] The working principle of this embodiment is as follows: During use, the interception net 4 inside the frame 3 is located at the front of the device facing the direction of water flow. When the water flow carries floating debris such as branches and plastic bags, the interception net 4 physically intercepts the debris, concentrating it in front of the frame 3 to prevent it from spreading downstream. After interception, it facilitates the work of the personnel to retrieve and clean it. When the interception net 4 becomes blocked and needs to be disassembled and cleaned, first pull the handle 10, which causes the two sets of limiting rods 8 to slide inside the fixed plate 7. During the sliding process, the two sets of limiting rods 8 will drive the baffle 9 to move together and compress the two sets of return springs 11. At this time, the limiting rods 8 gradually disengage from the limiting holes 6 on the top plate 5. After the limiting rods 8 are completely disengaged from the limiting holes 6, the frame 3 is then lifted upward by the connecting handle 21 at the top of the top plate 5. The frame 3 is then lifted by the sliding cooperation between the bottom positioning groove 13 of the frame 3 and the top positioning block 12 of the side plate 2. 3. The entire frame is disassembled from the base frame 1. After disassembly, the interception net 4 inside the frame 3 can be cleaned. After cleaning, the frame 3 is realigned with the positioning block 12 on the side plate 2, so that the positioning groove 13 slides into the positioning block 12 to complete the initial positioning. Then, the pull handle 10 is released, and the compressed return spring 11 releases its elastic potential energy, pushing the baffle 9 to move the limit rod 8 towards the top plate 5 until the limit rod 8 is re-inserted into the limit hole 6 of the top plate 5, completing the fixed connection between the frame 3 and the base frame 1, and restoring the interception net 4 to its working state. In use, after the drive motor 17 on one side of the base frame 1 starts, the worm 18 at its output end meshes with three sets of worm wheels 16, driving the worm wheels 16 fixed at the top of the rotating shaft 14 to rotate, thereby causing the rotating shaft 14 to rotate. The flow intercepting plate 15 connected to the outer wall of the rotating shaft 14 will rotate together with the rotating shaft 14. By controlling the direction and rotation angle of the drive motor 17, the tilt angle of the three sets of flow intercepting plates 15 can be adjusted synchronously. When the three sets of flow intercepting plates 15 are closed synchronously, their large-area plate surface blocks the water flow, achieving flow interception. When the three sets of flow intercepting plates 15 are opened synchronously, the water flow can pass through the gap between the plates, allowing flow regulation. The three sets of rotating shafts 14, flow intercepting plates 15 and worm wheels 16 are linked by the worm 18 to ensure synchronous rotation, avoiding water leakage due to lag in the action of a single component or angular deviation, thereby improving the stability and reliability of the flow interception process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
