Description

Technical Field

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-2 As shown, an embodiment of the present invention discloses a self-controlled flap gate device for water conservancy projects, comprising a fixing component 1, which includes a fixing base 101, a gate 102 rotatably connected to the fixing base 101, and a hydraulic rod 104 installed on the top end face of the fixing base 101 below the gate 102. The device is characterized in that an interception component 3 is rotatably connected to one side of the fixing component 1, and a limiting component 2 matching the interception component 3 is fixedly connected to one side wall of the fixing component 1. The fixing component 1 also includes a connecting rod 103, one end of which is rotatable. Connected to one side wall of the fixed component 1, the other end of the connecting rod 103 is rotatably connected to one side wall of the interception component 3. The bottom end face of the interception component 3 slides on the limiting component 2. When the gate is opened, the hydraulic rod 104 drives the gate 102 to flip, which in turn drives the interception component 3 to move away from the gate 102. This ensures that each time the gate is opened, it pushes the silt and debris away from the gate 102, thereby preventing the silt and debris from accumulating on one side of the gate 102 and the cleaning component 4, which would affect the normal opening and performance of the gate.

[0029] like Figures 3-4 As shown, an auxiliary block 1021 is fixedly connected to one side wall of the gate 102, and a fixed column is fixedly connected to the inner wall of the auxiliary block 1021. A rotating hole matching the fixed column is opened on the side wall of the connecting rod 103 near the gate 102. One end of the connecting rod 103 is located on the inner wall of the rotating hole and rotates on the outer wall of the fixed column. When the gate 102 flips, it drives the connecting rod 103 to rotate, so that the connecting rod 103 drives the interception panel 301 to move away from the gate 102.

[0030] like Figures 4-5As shown, the limiting component 2 includes a pair of limiting plates 201, both of which are integrally formed on one side wall of the fixed base 101. Each of the two limiting plates 201 has a limiting groove 2011 on its top end face, and a pair of support legs 202 are fixedly connected to the bottom end face of each of the two limiting plates 201. The interception component 3 includes an interception panel 301, both of which have interception side plates 302 integrally formed on their side end faces, and an interception bottom plate 303 integrally formed on its bottom end face. Each of the two interception side plates 302 has an avoidance hole 3021 that matches the cleaning component 4 on its outer wall. A pair of first sliders 304 that match the limiting groove 2011 are integrally formed on the bottom end face of the interception panel 301. The outer wall of the first slider 304 slides on the inner wall of the limiting groove 2011. When the interception component 3 moves away from the fixed component 1, the outer wall of the first slider 304 slides on the inner wall of the limiting groove 2011, which plays a certain limiting role and avoids damage to the interception component 3 due to a lot of silt and debris.

[0031] Furthermore, a cross-shaped cutting blade 305 is fixedly connected to one side wall of each pair of first sliders 304. When the first slider 304 slides in the limiting groove 2011, the cross-shaped cutting blade 305 cleans up the debris in front of it, so as to avoid blockage and affect the normal movement of the interception component 3.

[0032] Furthermore, several sets of water inlets 3011 are provided on the outer wall of the interception panel 301, so that the interception panel 301 can only intercept silt and debris in the water, and avoid affecting the normal flow of water when the gate is opened.

[0033] like Figure 2 and Figure 6As shown, the interception panel 301 has grooves 3012 on both the upper and lower side walls that match the cleaning component 4. The cleaning component 4 includes a pair of cleaning brackets 401. Steel ropes 404 are fixedly connected to the opposite outer walls of the pair of cleaning brackets 401. The other end of the pair of steel ropes 404 passes through the clearance hole 3021 and is fixedly connected to the side wall of the fixed base 101. Several sets of hooks 402 are fixedly connected to the side wall of the pair of cleaning brackets 401 near the interception panel 301. A cross-cutting blade 403 is fixedly connected between each pair of hooks 402. The pair of cleaning brackets 401 are located at the second slider 40. Elastic ropes 405 are fixedly connected to the inner wall of the 11. When the interception assembly 3 moves away from the gate 102, the distance between the interception assembly 3 and the fixed assembly 1 increases due to the fixed length of the steel rope 404. This causes a pair of cleaning brackets 401 to move to both sides on one side wall of the interception assembly 3. As the cleaning brackets 401 move to both sides, the grab hooks 402 clean the debris on the surface of the interception panel 301. At the same time, the cutting blade 403 cuts the debris to prevent it from accumulating and clogging the interception panel 301, thus affecting the normal flow of water. When the interception panel 301 moves closer to the gate 102, the pair of cleaning brackets 401 move closer to each other under the action of the elastic ropes 405, returning to their initial position.

[0034] When using, such as Figure 2 As shown, when the gate 102 flips, it causes the interception panel 301 to move away from the gate 102, pushing the silt and debris to the side away from the gate 102. Simultaneously, the cleaning component 4 cuts the debris, preventing excessive debris from causing blockage. Figure 1 As shown, the sludge is pushed to a more distant position. When the gate is closed, the interception panel 301 returns to its initial position to prevent it from adhering to one side of the interception component 3. Over time, this can cause blockage, requiring manual cleaning and affecting the normal use of the gate.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
