Description

Technical Field

[0001] This utility model relates to the field of flow channel technology, specifically to an acceleration flow channel used in water conservancy projects to increase the speed of water flow. Background Technology

[0002] In hydraulic engineering, acceleration channels are structures specifically designed to increase the velocity of water flow. Their main function is to accelerate the water flow within a certain area by adjusting the path, slope, or shape of the water flow, so as to more effectively guide the water flow to the target area. They are commonly used for purposes such as drainage, water conveyance, or hydroelectric power generation.

[0003] The applicant found through a search that a Chinese patent discloses "a rapid flow channel for water conservancy projects", with the publication number "CN222083461U". This patent facilitates the installation and disassembly of the rapid flow channel through a structure including a bottom layer, prefabricated side plates, locking blocks, T-slots, fixing plates, moving slots, moving blocks, limiting plates, springs, limiting rods, and limiting slots. The operation is simple and convenient, saves time, and improves the efficiency of construction work.

[0004] In the use of existing technology, the fixed structure means that drainage can only be discharged in the fixed direction of installation, which is not convenient to adjust as needed. This makes it unable to adapt to changes in different water flow conditions, thus affecting the versatility and adaptability of the equipment. At the same time, the device is not convenient to buffer the discharged water, which may lead to excessive impact force of the water flow, causing erosion of downstream soil or damage to facilities. Therefore, those skilled in the art provide an acceleration guide channel for increasing water flow velocity in water conservancy projects to solve the problems mentioned in the background art. Utility Model Content

An electric push rod is fixedly connected to one end of the sliding frame, and the other end of the electric push rod is fixedly connected to the inner wall of the drainage end.

[0011] As a preferred embodiment of the above technical solution, an intercepting net frame is rotatably connected to the sliding frame, a worm gear is fixedly connected to one end of the intercepting net frame, a worm is engaged with one side of the worm gear, and the worm is rotatably connected to the sliding frame.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: an acceleration guide channel for increasing the speed of water flow in a water conservancy project, including an inlet end 1, an acceleration end 2 fixedly connected to one side of the inlet end 1, a drainage end 3 on the other side of the acceleration end 2, an adjustment mechanism 4 for adjusting the drainage direction of the drainage end 3 fixedly connected to the acceleration end 2, and an interception mechanism 5 for dispersing the drainage impact force inside the drainage end 3.

[0022] By setting the adjustment mechanism 4, the drainage direction of the drainage end 3 can be adjusted as needed after the device is installed and fixed, so that the device can flexibly cope with these changes, improving drainage efficiency and adaptability. At the same time, by setting the interception mechanism 5, when the water discharged from the drainage end 3 will cause erosion of the downstream soil, the interception net frame 503 can effectively intercept and disperse the discharged water flow, avoiding high-speed water flow from directly impacting the downstream soil or vegetation, and reducing the risk of soil erosion and water loss.

[0023] As one implementation method in this embodiment, please refer to Figure 2 As shown, the acceleration end 2 has a structure with one end having a large opening and the other end having a small opening. A rubber connecting end 201 is fixedly connected to one end of the acceleration end 2 near the drainage end 3, and the other end of the rubber connecting end 201 is fixedly connected to the drainage end 3.

[0024] The accelerating end 2 has a structure with a large opening at one end and a small opening at the other end, which helps to increase the water flow speed and improve drainage efficiency. The rubber connecting end 201 ensures that the connection can still be maintained when the drainage end 3 rotates.

[0025] As one implementation method in this embodiment, please refer to Figure 3 As shown, a connecting frame 301 is fixedly connected to the drain end 3, and a rotating shaft 302 is fixedly connected to the other end of the connecting frame 301. The adjusting mechanism 4 includes a fixed frame 401, and the rotating shaft 302 is rotatably connected to the fixed frame 401. A sliding groove 303 is provided on the connecting frame 301.

[0026] The rotating shaft 302 can limit and stabilize the rotation of the drain end 3.

[0027] As one implementation method in this embodiment, please refer to Figure 3 As shown, the fixed frame 401 is fixedly connected to the acceleration end 2. A lead screw 402 is rotatably connected through the fixed frame 401. A push shaft 403 is threadedly connected to the outer wall of the lead screw 402. One end of the push shaft 403 is slidably engaged with the fixed frame 401, and the other end of the push shaft 403 is slidably engaged with the inner wall of the slide groove 303.

[0028] The drive shaft 403 enables adjustment of the angle of the drain end 3.

[0029] As one implementation method in this embodiment, please refer to Figure 4 As shown, the interception mechanism 5 includes a sliding frame 501, which is slidably engaged with the inner wall of the drainage end 3. One end of the sliding frame 501 is fixedly connected to an electric push rod 502, and the other end of the electric push rod 502 is fixedly connected to the inner wall of the drainage end 3.

[0030] The electric actuator 502 enables the automatic extension and retraction of the interception mechanism 5.

[0031] A net frame 503 is rotatably connected to the sliding frame 501. A worm gear 504 is fixedly connected to one end of the net frame 503. A worm 505 is meshed and driven on one side of the worm gear 504. The worm 505 is rotatably connected to the sliding frame 501.

[0032] The worm gear 505 enables the interception net frame 503 to be in an inclined interception state, which can both divert water flow to reduce impact force and prevent debris from accumulating on the interception net frame 503.

[0033] A universal joint 506 is fixedly connected to one end of the worm gear 505. The universal joint 506 is rotatably connected to the sliding frame 501. An adjusting wheel 507 is fixedly connected to the other end of the universal joint 506. An adjusting rack 508 is engaged on one side of the adjusting wheel 507. The adjusting rack 508 is fixedly connected to the inner wall of the drain end 3.

[0034] Adjusting the rack 508 enables automatic adjustment of the angle of the intercepting mesh frame 503.

[0035] Working principle: When it is necessary to increase the water flow velocity of a water conservancy project, the device is first installed in a suitable position. Then, by rotating the lead screw 402, the lead screw 402 can drive the push shaft 403 to move. At this time, the push shaft 403 will slide in the slide groove 303, thereby driving the drainage end 3 to rotate around the rotating shaft 302 as the center, thus adjusting the drainage direction. The water flow first enters from the inlet end 1, and then gradually flows out through the smaller opening after passing through the acceleration end 2, which helps to increase the water flow velocity. When it is necessary to disperse the water discharged from the drainage end 3 to reduce the impact force, the electric push rod 502 drives the connected sliding frame 501 to move out. When the interception net frame 503 is completely moved out, the adjusting wheel 507 will mesh with the adjusting rack 508, thereby causing the adjusting wheel 507 to drive the worm gear 505 connected to the universal joint 506 to rotate. This allows the worm gear 505 to drive the interception net frame 503 connected to the worm wheel 504 to be in an inclined state, intercepting the discharged water flow and reducing its impact force.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
