[0003] When the plug-in plate type water gate is opened, water flows through the valve body. At this time, part of the silt or sundries in the water will silt in the sealing groove, blocking the sealing groove, and over time, the silt will form into a block of mud. If the water gate is closed again, when the valve plate is lowered, the silt will block the lower end of the valve plate from entering the sealing groove, so that the water gate is not tightly closed, resulting in water leakage.

DETAILED DESCRIPTION

[0026] for example Figure 6 and Figure 7As shown, the existing slide gate includes a rectangular frame valve body 6 with vertical grooves on both sides inside the valve body 6 and an upward-opening sealing groove 18 at the bottom. A valve plate 19 is inserted inside the valve body 6, surrounded by rectangular frame plates 5. The frame plates 5 on both sides are located in their respective grooves, and the bottom frame plate 5 is located in the sealing groove 18. A bracket 3 is fixedly installed on the top of the valve body 6, and an electric actuator 1 is installed on the top of the bracket 3. A valve stem 2 is located in the middle of the valve plate 19. When the electric actuator 1 operates, it moves the valve plate 19 up and down via the valve stem 2, thereby opening or closing the slide gate.

[0027] Example 1

[0028] like Figures 1 to 4 As shown, a sluice gate that can prevent siltation has been improved based on the existing slide gate as follows.

[0029] The sealing groove 18 is provided with a long rectangular blocking plate 8. The bottom of the valve body 6 is a long rectangular base plate 12, which is located at the bottom of the sealing groove 18 and is fixedly connected to the bottom of the valve body 6 by hexagonal screws. An upper spring seat 9 is fixedly connected to the bottom of the blocking plate 8. There are four upper spring seats 9 evenly distributed along the length of the blocking plate 8. Four lower spring seats 11 are fixedly connected to the top of the base plate 12, with each lower spring seat 11 corresponding to one of the four upper spring seats 9. Each upper spring seat 9 and its corresponding lower spring seat 11 are coaxial and vertical, and both the upper spring seat 9 and lower spring seat 11 are cylindrical. A spring 10 is provided outside the lower spring seat 11. The lower part of the spring 10 fits over the upper spring seat 9, and the upper part of the spring 10 fits over the upper spring seat 9. The upper end of the spring 10 rests against the bottom of the blocking plate 8, and the lower end of the lower spring 10 rests against the top of the base plate 12.

[0030] When the valve plate 19 descends and the sluice gate closes, the bottom of the frame plate 5 is inserted into the sealing groove 18, and the upper spring seat 9 and the lower spring seat 11 are in contact. The top surface of the blocking plate 8 is lower than the top surface of the sealing groove 18. When the valve plate 19 rises and the sluice gate opens, under the action of the spring 10, the blocking plate 8 moves upward and becomes flush with the top surface of the sealing groove 18.

[0031] Therefore, when the sluice gate is opened, the blocking plate 8 will block the opening at the top of the sealing groove 18, so the water carrying silt will flow over the blocking plate 8, and the silt in the water will not settle into the sealing groove 18. When the sluice gate is closed again, since there is no longer any silt accumulation inside the sealing groove 18, the valve plate 19 can be smoothly inserted into the sealing groove 18, thus ensuring the seal between the valve plate 19 and the valve body 6, and therefore the sluice gate will not leak.

[0032] Each lower spring seat 11 has a frustum-shaped boss 13 with its smaller diameter end facing upwards at the top, and each upper spring seat 9 has a recess 14 at the bottom corresponding to the shape of the boss 13. Through the cooperation of the boss 13 and the recess 14, the lower spring seat 11 and the upper spring seat 9 can be automatically aligned when in contact, preventing the blocking plate 8 from shifting.

[0033] Example 2

[0034] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that:

[0035] Water pipes 15 are fixedly installed on both sides of the valve body 6. The lower ends of the water pipes 15 are connected to both ends of the sealing groove 18 respectively. The lower ends of the water pipes 15 are close to the bottom of the sealing groove 18, and the upper ends of the water pipes 15 extend out of the water surface. One of the water pipes 15 is connected to an external pressure water source.

[0036] Clean pressurized water is periodically introduced into one of the water pipes 15 to flush out fine dust and sand in the sealing groove 18, and then discharged from the other water pipe 15 to keep the sealing groove 18 clean, so that the valve plate 19 can close more smoothly and prevent jamming.

[0037] Example 3

[0038] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that:

[0039] The boss 13 and recess 14 are no longer provided. A limiting rod 16 is provided between the lower spring seat 11 and the upper spring seat 9. The limiting rod 16 is slidably connected to the lower spring seat 11 and fixedly connected to the upper spring seat 9. The lower end of the limiting rod 16 is provided with a flange for axially limiting the limiting rod 16. In actual production, the limiting rod 16 is made of hexagon socket head cap screw.

[0040] The lower spring seat 11 has a vertical sliding hole 17 at its center. The nut of the hex socket screw is located inside the sliding hole 17, and the nut slides in fit with the lower spring seat 11. The shank of the hex socket screw passes through the top of the lower spring seat 11 and is screwed onto the bottom of the upper spring seat 9. The base plate 12 has a through hole communicating with the sliding hole 17.

[0041] The device includes a valve body 6, a valve plate 19 slidably connected within the valve body 6, and a bracket 3 and an electric actuator 1 fixedly connected from bottom to top to the top surface of the valve body 6. A nut 4 is fixedly installed on the valve body 6, and the electric actuator 1 is driven by a vertical valve stem 2. The valve stem 2 is threadedly connected to the nut 4.

[0042] The position of the blocking plate 8 after moving up is limited by the limiting rod 16. When the water gate is opened, the valve plate 19 moves up, and under the elastic action of the spring 10, the blocking plate 8 moves up, so that the top surface of the blocking plate 8 is flush with the slot of the sealing groove 18. Through the limiting action of the limiting rod 16, the blocking plate 8 can be prevented from being pushed out of the sealing groove 18 by the spring 10, thereby preventing the mud from entering the sealing groove 18 and affecting the closing of the valve plate 19.

[0043] The central pipe 7 is vertically arranged in the middle of the valve plate 19, the lower end of the central pipe 7 is closed, the upper end of the central pipe 7 is open, the nut 4 is fixedly connected with the top end of the central pipe 7, and the lower end of the valve rod 2 extends into the central pipe 7. The valve rod 2 is threadedly connected with the nut 4, and the upper end of the valve rod 2 is drivingly connected with the output shaft of the electric head 1. When the electric head 1 operates, the valve rod 2 is rotated, and under the action of the valve rod 2 and the nut 4, the valve plate 19 is moved up and down. When the valve plate 19 is lifted, the lower part of the valve rod 2 enters the central pipe 7.

[0044] The central pipe 7 plays a role in increasing the rigidity of the valve plate 19, and since the valve rod 2 enters the central pipe 7 when the valve plate 19 is opened, the valve rod 2 will not be lifted upward, so that the vertical space occupied by the utility model is smaller.

[0045] The above-described embodiment describes the content in more detail and concretely, expresses the preferred embodiment of the utility model, and is only used for explaining the technical idea and characteristics of the utility model, and its purpose is to enable the person skilled in the art to understand the content of the utility model and to implement it, but it is not limited to the utility model, and the patent range of the utility model cannot be limited by the embodiment, that is, any equivalent change or modification of the utility model disclosed by the utility model, the partial improvement of the system and the change between the subsystems without departing from the structure of the utility model, the transformation, etc. of the utility model are still within the patent range of the utility model.
