[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] See also Figure 1-4 In this embodiment, a water conservancy and hydropower gate with a safety protection function includes a base 1, a gate seat 2 fixedly installed on the base 1, an opening and closing door 3 movably installed in the gate seat 2, and a driving member for controlling the movement of the opening and closing door 3. The base 1 can adopt an inclined surface with a trapezoidal cross-section to reduce the possibility of objects piling up under the opening and closing door 3.

[0023] In this embodiment, the driving member in the gate seat 2 is an electric motor, which transmits power to the gate through a transmission device, thereby realizing the opening and closing of the gate. The motor can be a DC motor or an AC motor. In addition to the motor, the gate may also be hydraulically driven or pneumatically driven. The hydraulic drive system realizes the movement of the gate through a hydraulic cylinder or a hydraulic motor, while the pneumatic drive system realizes the movement of the gate through a pneumatic cylinder or a pneumatic motor.

[0024] It should be noted that a filter element for blocking filtration is arranged inside the gate seat 2, and a connecting component for transmission control of the filter element is arranged at the lower end of the opening and closing door 3.

[0025] The filter element in this embodiment includes a slider 5 slidably mounted on the inner wall of the gate seat 2, and a filter plate 6 fixedly connected to the slider 5. Slide grooves 4 are provided on both sides of the inner wall of the gate seat 2, and the slider 5 is slidably connected to the slide grooves 4. The sliding of the slider 5 can improve the activity stability of the filter plate 6.

[0026] In this embodiment, a plurality of filter holes arranged in an array are evenly formed on the filter plate 6 for filtering aquatic impurities to maintain the aquatic environment.

[0027] It should be noted that the connecting component includes a mounting frame 8 slidably mounted on the outside of the opening and closing door 3, a gear shaft 9 rotatably mounted on the mounting frame 8, and a rack rack 7 fixedly mounted on the side of the filter plate 6 facing the opening and closing door 3. The rack rack 7 is toothed in meshing engagement with the gear shaft 9. Since the gear shaft 9 can be freely rotated on the mounting frame 8, the position of the filter plate 6 will not be affected when the opening and closing door 3 is lifted to different extents.

[0028] In order to facilitate the control of the filter plate 6 as the filter plate 6 is lowered and raised as the opening and closing door 3 is opened and closed, an adjusting device is provided in the opening and closing door 3, the adjusting device includes a slide plate 10 slidably installed in the opening and closing door 3, a tooth plate 11 fixedly installed on the side of the slide plate 10 facing the outside of the filter plate 6, and an adjusting member built into the opening and closing door 3, the tooth plate 11 is toothed in meshing with the gear shaft 9, and the position of the tooth plate 11 can be changed by the slide plate 10, so that the opening and closing door 3 can adjust its matching state relative to the gear shaft 9.

[0029] In this embodiment, the adjusting member includes an adjusting motor 14 fixedly installed in the opening and closing door 3, and a cam 13 fixedly installed on the output end of the adjusting motor 14. The cam 13 is attached to the two slides 10 and can be driven to rotate by the adjusting motor 14. When the cam 13 rotates, the two slides 10 are pushed away from each other, so that the tooth plate 11 extends to the outside of the opening and closing door 3.

[0030] The regulating motor 14 is configured as a self-locking motor for realizing self-locking after the cam 13 is pulled.

[0031] It should be noted that openings 12 are provided on both the front and rear side surfaces of the opening and closing door 3 , and the toothed plate 11 is slidably fitted in the opening 12 , so that the opening and closing door 3 has a certain sealing performance.

[0032] In this embodiment, a compression spring 15 is fixedly installed between the slide plate 10 and the inner wall of the opening and closing door 3, and the compression spring 15 is used to push the slide plate 10 to achieve reset.

[0033] The working principle of the above embodiment is:

[0034] When the opening and closing door 3 needs to be opened, the cam 13 is driven to rotate by controlling the adjusting motor 14, so that the cam 13 rotates and resets. At this time, the tooth plate 11 retracts into the opening and closing door 3 under the elastic force of the compression spring 15. At this time, the filter plate 6 is not restricted in position and can be lowered by sliding the sliders 5 on both sides relative to the slide 4. Then, the position of the filter plate 6 can be realized without interfering with the filter plate 6 by controlling the opening and closing door 3 to be opened. When the filter plate 6 needs to be reset, the cam 13 is driven to rotate by controlling the adjusting motor 14, and the two slide plates 10 are squeezed by the two ends of the cam 13 to slide in the opening and closing door 3, so that the tooth plate 11 on the slide plate 10 can extend to the outside of the opening 12 and mesh with the gear shaft 9. At this time, when the opening and closing door 3 is pushed downward, the tooth plate 11 can be attached to the gear shaft 9, and the gear shaft 9 can mesh with the rack frame 7 at the same time, so as to realize the lifting and reset of the filter plate 6.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0036] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
