The pressure measuring table 128 is fixedly installed on the outer surface of the driving pipeline 115 in a radial direction, the pressure measuring piston rod 129 is slidingly and sealingly inserted into the pressure measuring table 128, the axis of the pressure measuring piston rod 129 is perpendicular to and intersects with the axis of the driving pipeline 115, the end of the pressure measuring piston rod 129 away from the axis direction of the driving pipeline 115 is fixedly installed with the extrusion plate 131, the pressure sensor 130 is arranged in contact between the extrusion plate 131 and the pressure measuring table 128, the extrusion plate limiting frame 132 is arranged on the extrusion plate 131 in a lapping manner, the extrusion plate limiting frame 132 is fixed on the pressure measuring table 128, and the extrusion plate limiting frame 132 is used to prevent the pressure measuring piston rod 129 from being separated from the pressure measuring table 128. The helical plate 134 is arranged on the inner wall of the water inlet pipe 133 along the axis direction of the water inlet pipe 133.

[0026] The working principle of the Pengze carp ciliates disease prevention device is as follows: the water inlet pipe 133 is connected to the pipeline, and then the other end of the pipeline is inserted into the water tank. The water outlet pipe 114 is connected to the pipeline, and the other end of the pipeline is inserted into the water tank. The distance between the two pipelines inserted into the water tank is the farthest in the water tank. Start the driving motor 103, and the output shaft of the driving motor 103 drives the input circular frame 125 to rotate. The input circular frame 125 drives the electromagnet sliding chamber 139 to rotate. The electromagnet sliding chamber 139 drives the input turntable 124 to rotate. The input turntable 124 drives the gear ring 123 to rotate. The gear ring 123 drives the aluminum gear 121 to rotate through the planetary gear 122 (the planetary gear disc rotating table 141 is internally provided with an electromagnetic winding. At this time, the electromagnetic winding is electrified to generate a magnetic force which attracts the planetary gear disc 120, so that the planetary gear disc 120 and the planetary gear disc rotating table 141 form a friction fixed relationship). The rotation of the aluminum gear 121 will drive the turbine paddle 117 to rotate through the transmission shaft 119. The turbine paddle 117 drives the liquid in the driving pipeline 115 to flow (water needs to be filled in the equipment and the pipeline connected with the water inlet pipe 133 before use). At this time, the water in the separation chamber 104 will enter the driving pipeline 115 through the stainless steel filter screen cylinder 137 and the sand particles. The water in the water tank will enter the double-foot sedimentation chamber 105 through the water inlet pipe 133 (due to the increase in space, the flow rate will decrease). In this process, the water will rotate under the action of the spiral plate 134. When it moves to the top of the water inlet pipe 133 and separates from the water inlet pipe 133, the rotating water will continue to rotate under the action of inertia. Therefore, the solid substances sucked into the driving pipeline 115 along with the water will also rotate. When they separate from the water inlet pipe 133, they will be thrown away from the water inlet pipe 133 and fall onto the spiral feeding rod 107 under the action of gravity. Then, the slag discharge motor 108 is started. The output shaft of the slag discharge motor 108 drives the two spiral feeding rods 107 to rotate through the chain 116 (first drive one of the spiral feeding rods 107 to rotate, and then make the two spiral feeding rods 107 rotate at the same time through the chain 116). The spiral feeding rod 107 rotates to discharge the sediment at the bottom of the double-foot sedimentation chamber 105. The water enters the separation chamber 104 through the gap between the intermediate separation baffle 135 and the inner wall of the double-foot sedimentation chamber 105, and then passes through the stainless steel filter screen cylinder 137 and the sand particles to enter the driving pipeline 115. This process will cause the fine particles and microorganisms (Myxobolus spores and intermediate hosts of the Myxobolus spores) in the water to stay outside the stainless steel filter screen cylinder 137 and inside the sand particles. The activated state of the heating rod 118 is started to inactivate these microorganisms. Specifically, the heat of the heating rod 118 can be directly transmitted to the water, and at the same time, it can also be transmitted to the sand, so as to simultaneously heat the sand and the water.The water entering the inside of the driving pipe 115 will enter the inside of the light box 101, and then pass through the multiple transparent acrylic plates 109 in turn to the water outlet 111, and then be discharged through the water outlet pipe 114 to be recycled in the water. In this process, the ultraviolet lamp 112 needs to be started, and the ultraviolet lamp 112 emits ultraviolet light, which is guided by the transparent glass sealing plate 110 and the transparent acrylic plate 109 to irradiate the water in the inside of the light box 101, further inactivating the microorganisms in the water.

[0027] With the passage of time, the circumference surface of the stainless steel filter screen cylinder 137 will deposit a layer of blockage, so it is necessary to eliminate the blockage. At this time, since the turbine paddle 117 is known to be in a working state, when the stainless steel filter screen cylinder 137 is blocked, it will cause the amount of water entering the inside of the stainless steel filter screen cylinder 137 to decrease, so the pressure in the inside of the stainless steel filter screen cylinder 137 will decrease (the pressure measuring piston rod 129 is arranged at a position between the turbine paddle 117 and the stainless steel filter screen cylinder 137), at this time the external air pressure will push the pressure measuring piston rod 129 to the inside of the driving pipe 115, and then the force is applied to the pressure sensor 130 through the extrusion plate 131, and the pressure sensor 130 is used to judge whether the stainless steel filter screen cylinder 137 is blocked. If the stainless steel filter screen cylinder 137 is blocked, the system starts the scraping motor 136, the output shaft of the scraping motor 136 drives the scraper 138 on the scraper support 140 to rotate, and the scraper 138 scrapes the deposits on the surface of the stainless steel filter screen cylinder 137. At the same time, the electromagnet 127 is started, and the electromagnetic winding in the inside of the planetary gear disc rotating table 141 is stopped, at this time the planetary gear disc 120 is in a rotatable state, the magnetic friction between the electromagnet 127 and the aluminum gear 121 causes the electromagnet 127 and the aluminum gear 121 to be in a fixed state. At this time, the rotation of the tooth ring 123 will directly drive the aluminum gear 121 to rotate, and the rotation direction of the aluminum gear 121 is changed, which will cause the turbine paddle 117 to rotate in the opposite direction, so that the water in the inside of the driving pipe 115 flows to the inside of the stainless steel filter screen cylinder 137, and the stainless steel filter screen cylinder 137 and the sand particles are backwashed to further eliminate the blockage.
