And inside the buckle 105, a plug rod 109 is snap-fitted. At the bottom of the plug rod 109, a spring 108 is fixedly connected. And outside the spring 108, a metal shell 107 is arranged; the sealing door 104 forms a rotating structure with the overall housing 101 through the hinge 103. And the sealing door 104 and the buckle 105 are integrally arranged. The buckle 105 and the plug rod 109 form a snap-fitting structure. And the plug rod 109 forms an elastic structure with the metal shell 107 through the spring 108; the water inlet pipe 102 forms a communicating structure with the overall housing 101. And the overall housing 101 forms a communicating structure with the water outlet pipe 106.

[0028] Please refer to Figure 4 A mechanical water filtration device for a hydropower station, as shown, the filter net assembly 2 includes a slide rod 201. At the top of the slide rod 201, a first filter screen 202 is slidably connected. And on the side of the first filter screen 202, a handle 204 is fixedly connected. And inside the first filter screen 202, filter cotton 203 is arranged. At the bottom of the first filter screen 202, a second filter screen 205 is arranged. And at the bottom of the second filter screen 205, a third filter screen 206 is arranged; the first filter screen 202 forms a sliding structure with the overall housing 101 through the slide rod 201. And the first filter screen 202 and the handle 204 are integrally arranged.

[0029] Please refer to Figure 5A mechanical water filtration device for a hydropower station is shown. The alarm reminder component 3 includes a liquid level sensor 301. A relay 302 is fixedly connected to the top of the liquid level sensor 301. A connecting wire 303 is fixedly connected to the side of the relay 302. A power supply 304 is fixedly connected to the end of the connecting wire 303. A warning light 305 is arranged on the side of the power supply 304. The liquid level sensor 301 and the relay 302 are electrically connected. The relay 302 is electrically connected to the power supply 304 through the connecting wire 303. And the power supply 304 and the warning light 305 are electrically connected. The liquid level sensor 301 is a pressure sensor for measuring the liquid level. The static pressure input type liquid level transmitter (liquid level gauge) is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses an isolated diffused silicon sensitive element or a ceramic capacitive pressure sensitive sensor to convert the static pressure into an electrical signal, and then through temperature compensation and linear correction, it is converted into a standard electrical signal.

[0030] Working principle: First, connect the water inlet pipe 102 to an external device. Under the action of the external device, mechanical water enters the interior of the overall housing 101 through the water inlet pipe 102. After the mechanical water enters the interior of the overall housing 101 through the water inlet pipe 102, it falls into the first filter screen 202. The holes of the first filter screen 202 are relatively large, filtering out some larger impurities and leaving the impurities on the filter cotton 203. Then it flows through the holes at the bottom of the first filter screen 202 into the second filter screen 205. The holes of the second filter screen 205 are smaller than those of the first filter screen 202 for further filtration. The mechanical water flows through the second filter screen 205 into the third filter screen 206. The filter holes of the third filter screen 206 are more delicate for final filtration. Then it flows out through the water outlet pipe 106. When the filter screens need to be cleaned and replaced after working for a period of time, first drain the water inside the overall housing 101. Then, push down the insertion rod 109 to open the sealing door 104. Slide out the first filter screen 202 through the sliding rod 201, remove the filter cotton 203, and then clean the first filter screen 202. After cleaning, put the first filter screen 202 back. The second filter screen 205 and the third filter screen 206 are cleaned in the same way. After cleaning, close the sealing door 104 and fix it with the buckle 105 and the insertion rod 109, and seal it under the action of the sealing ring 110. When the filter holes are blocked during the filtration process, the mechanical water inside the screen will increase. When it reaches a certain amount, it is sensed by the liquid level sensor 301. The signal is converted through the relay 302 and then transmitted through the connecting wire 303 to turn on the warning light 305 to remind the staff. The staff can observe the position of the warning light 305 to deal with the filter screen.
