It is the energy that causes volcanic eruptions and earthquakes. The high temperature of the molten rock heats the nearby groundwater, which eventually seeps out of the ground. The simplest and most cost-effective way to use geothermal energy is to directly access these heat sources and extract their energy.

When the push rod 47 no longer pushes the filter screen 42, the return spring 49 will drive the connecting block 48 to reset through its own elastic force, thereby resetting the filter screen 42. The end of the push rod 47 away from the rack 45 fits the filter screen 42. The outer wall of the reciprocating screw 46 is threadedly connected with a slider 7. The slider 7 will slide left and right with the rotation of the reciprocating screw 46. The top surface of the inside of the filter box 1 is slidably connected to the slider 7. The end of the slider 7 away from the top surface of the inside of the filter box 1 is fixedly connected to the sleeve 8. The sleeve 8 will move with the movement of the slider 7.

When the cleaning brush 13 moves to the left, it does not fit the filter screen 42. At this time, the cleaning brush 13 will not drive the impurities to move. The inner wall of the filter box 1 is fixed with a water filter. Pump 15, the output end of the water pump 15 is fixed with a water outlet pipe 6, the water outlet pipe 6 penetrates the left wall of the filter box 1 and is fixedly connected to the penetration of the filter box 1, the water pump 15 can discharge the filtered water into the water tank 2 through the water outlet pipe 6, the water outlet pipe 6 penetrates the right wall of the water tank 2 and is fixedly connected to the penetration of the water tank 2, the top of the water tank 2 is fixed with a water inlet pipe 5, the filtered water in the water tank 2 will be discharged into the main body 3 through the water inlet pipe 5 for use, the end of the water inlet pipe 5 away from the water tank 2 is fixedly connected to the main body 3, the bottom of the main body 3 is provided with a water inlet 16, the water inlet 16 penetrates the filter box 1 and is fixedly connected to the penetration of the filter box 1, the water used by the main body 3 will enter the filter box 1 through the water inlet 16 for filtration. ;

[0025] Working principle: When water enters the filter box 1 from the water inlet 16, the water flow will flush the impeller 41, thereby causing the impeller 41 to rotate, so that the reciprocating screw 46 rotates with the impeller 41, and then the half-circle gear 43 is driven to rotate through the reciprocating screw 46. When the tooth groove of the half-circle gear 43 engages the rack 45, the rotation of the half-circle gear 43 will drive the rack 45 to move toward the filter screen 42. At this time, the push rod 47 will move in the direction of the filter screen 42 along with the movement of the rack 45. At this time, the return spring 44 will be in a stretched state due to the movement of the rack 45. The filter screen 42 is pushed downward by the push rod 47. At this time, the filter screen 42 drives the connecting block 48 to move downward, so that the return spring 49 is in a compressed state due to the downward movement of the connecting block 48. When the half-circle gear 43 rotates so that its own tooth groove is not engaged with the rack 45, the return spring 44 will contract by its own elastic force, thereby driving the rack 45 to move away from the filter screen 42, thereby causing the push rod 47 to move away from the filter screen 42. At this time, the push rod 47 no longer pushes the filter screen 42, and the return spring 49 will contract by its own elastic force. The elastic force drives the connecting block 48 to reset, thereby resetting the filter screen 42, thereby realizing the reciprocating up and down shaking of the filter screen 42. At the same time, when the reciprocating screw rod 46 rotates, the slider 7 will slide left and right along the top surface of the filter box 1 with the rotation of the reciprocating screw rod 46. At this time, the sleeve 8 will move with the movement of the slider 7, thereby driving the sleeve rod 9 to move left and right, and the sleeve rod 9 will drive the sliding shaft 11 to move. When the sliding shaft 11 moves to the right, the sliding shaft 11 will slide on the bottom surface of the sliding groove 10. When the sliding shaft 11 moves to the rightmost end of the sliding groove 10, the auxiliary The auxiliary spring 14 will drive the sleeve rod 9 to move upward through its own elastic force, and then drive the sliding shaft 11 to move upward along the inner wall of the slide groove 10, so that the sliding shaft 11 is at the top surface of the slide groove 10 when it moves to the left. When the sliding shaft 11 moves to the leftmost end of the slide groove 10, the sliding shaft 11 will move downward along the inner wall of the slide groove 10, thereby driving the sleeve rod 9 to move downward, so that the cleaning brush 13 is in contact with the filter screen 42 when it moves to the right, and the impurities are cleaned out of the filter box 1. When the cleaning brush 13 moves to the left, it does not fit with the filter screen 42, and the cleaning brush 13 will not drive the impurities to move.
