[0021] Such as Figure 1As shown in the figure, a gate device for hydropower generation includes a valve body 1 and an adjustable spool mechanism 2 arranged inside the valve body 1. The adjustable spool mechanism 2 is used to adjust the spool pressure. It also includes a filtering component 3 arranged on one side of the adjustable spool. The filtering component 3 is used to filter the fluid passing through the valve body 1. One end of the valve body 1 is provided with a water inlet 4, and the lower end of the valve body 1 is provided with a water outlet 5.

[0022] As Figures 2-4 shown, the adjustable spool mechanism 2 includes a pull rod 6, a baffle 7 and a positioning enclosure 8. The pull rod 6 is slidably arranged inside the valve body 1, and one end of the pull rod 6 passes through one side of the valve body 1. A fixing nut 9 is arranged at the part of the pull rod 6 outside the valve body 1. The baffle 7 is fixedly connected to the other end of the pull rod 6, and the positioning enclosure 8 is fixedly connected to the inner wall of the valve body 1. A spring 10 is arranged between the baffle 7 and the valve body 1.

[0023] As Figures 2-3 shown, the filtering component 3 includes a support plate 11 and a varistor 12. A support plate 11 is fixedly connected to the periphery of the baffle 7, and the varistor 12 is fixedly connected to the inner wall surface of the valve body 1. Filter holes 13 are arranged in the upper part of the support plate 11, and a slag discharge port 14 is arranged at the lower end of the valve body 1. The slag discharge port 14 is communicated with a slag discharge valve.

[0024] Among them, the spring 10 is sleeved on the upper part of the pull rod 6. One end of the spring 10 contacts the baffle 7, and the other end of the spring 10 contacts the varistor 12. The water outlet 5 is arranged at the lower end between the positioning enclosure 8 and the valve body 1. The slag discharge port 14 is arranged at the lower end between the positioning enclosures 8. The support plate 11 is tightly connected to the inner wall surface of the valve body 1. A microprocessor is fixedly connected to one side of the valve body 1. The varistor 12 is connected to the microprocessor through a wire, and the microprocessor is connected to the slag discharge valve through a wire.

[0025] During specific use, water is poured into the valve body 1 through the water inlet 4. The water flow passes through the filter holes 13 in the upper part of the support plate 11, filters the impurities carried by the water flow, and flows out through the water outlet 5. When the impurities block the filter holes 13, the baffle 7 is pushed to move. When the baffle 7 abuts against the positioning enclosure 8, the valve body 1 stops supplying water. Under the action of the elastic deformation pressure of the spring 10, the varistor 12 monitors the pressure and sends an electrical signal to be conducted to the microprocessor. The microprocessor opens the slag discharge valve, and the water flow flushes the impurities on the filter holes 13 and discharges them through the slag discharge port 14.

[0026] By the threaded connection between the fixing nut 9 and the pull rod 6, the elastic deformation of the spring 10 is changed. The baffle 7 and the support plate 11 slide between the positioning enclosures 8 to adjust the opening degree of the gate, realize precise flow control, and optimize the power generation efficiency.

[0027] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. In general, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present utility model, design similar structural methods and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
