[0015] 2. Before the initial start-up of the self-priming pump of the present invention, the pump body needs to be filled with water from the liquid filling port. After the pump is started, the filled water is discharged to form a vacuum, and the liquid under the ground is sucked in from the liquid suction port, and the liquid is discharged to the desired destination through the impeller and the liquid outlet. However, during the operation of the self-priming pump, the pump may not pump due to leakage in the flange and weld, and failure of the inlet solenoid valve. The most intuitive reaction to this situation is that the liquid inside the pump body is drained. Designing a glass tube liquid level gauge at the pump body can observe the liquid level most directly, so as to judge the phenomenon and analyze the cause when the self-priming pump does not pump, and then quickly deal with the defects, so that the operator can judge the liquid level in the self-priming pump in time and accurately, and determine that the self-priming pump meets the starting conditions. When the self-priming pump fails to work, the cause of the problem can be effectively located through the liquid level in the pump body, which is convenient for the next step of processing.

DETAILED DESCRIPTION

[0021] like Figures 1 to 4 As shown, an internal liquid detection device of a vacuum self-priming pump provided by an embodiment of the present invention includes a cleaning shell 1 and a filtering cleaning component 14, a liquid suction port 6 is provided on one side of the cleaning shell 1, the upper surface of the cleaning shell 1 is connected to a conveying tank 2, a liquid filling port 7 is installed on the front surface of the conveying tank 2, a liquid outlet 8 is provided on the other side surface of the conveying tank 2, an exhaust port 9 is installed at one end of the liquid outlet 8, a driving motor 3 is fixedly connected to the upper surface of the conveying tank 2, a connecting line 4 is electrically connected to one side of the driving motor 3, and the other end of the connecting line 4 is electrically connected to an electric control valve 5, and the electric control valve 5 is arranged above one end of the liquid suction port 6.

[0022] The output shaft of the driving motor 3 is fixedly connected to the No. 1 rotating shaft 11, and the No. 1 rotating shaft 11 is rotatably installed in the bearing 10, and the bearing 10 is arranged in the bearing mounting plate 12, and the bearing mounting plate 12 is fixedly connected to the upper part of the inner wall of the conveying tank 2, and the No. 2 sleeve ring 13 is fixedly connected to the lower part of the inner wall of the conveying tank 2, and the lower end of the No. 1 rotating shaft 11 is fixedly connected to the impeller mounting plate 17, and the lower surface of the impeller mounting plate 17 is fixedly connected to the impeller 18, and the filter cleaning component 14 is installed on the outer side of the impeller 18, and the inner filter plate 16 is installed on the filter cleaning component 14. The filter cleaning component 14 is located in the cleaning shell 1, and the inner side of the cleaning shell 1 is fixedly connected to the outer filter plate 15. Before the initial start of the self-priming pump, the pump body needs to be filled with water from the liquid filling port 7, and the filled water is filled after the pump is started. The discharge forms a vacuum, and the liquid under the ground is sucked in from the liquid suction port 6, and the liquid is discharged to the desired location through the impeller 18 and the liquid outlet 8. However, during the operation of the self-priming pump, the flange and weld leakage, as well as the failure of the inlet solenoid valve may cause the pump to not pump. The most intuitive reaction to this situation is that the liquid inside the pump body is drained. The design of a glass tube liquid level gauge at the pump body can observe the liquid level most directly, so as to judge the phenomenon and analyze the cause when the self-priming pump does not pump, and then quickly deal with the defects, so that the operator can judge the liquid level in the self-priming pump in time and accurately, and determine that the self-priming pump meets the starting conditions. When the self-priming pump fails to work, the cause of the problem can be effectively located through the liquid level in the pump body, which is convenient for the next step of processing.

[0023] The filter cleaning assembly 14 includes a No. 1 collar 401, which is fixedly sleeved in the middle of the No. 1 rotating shaft 11. A plurality of evenly distributed connecting rods 402 are fixedly connected to the outer surface of the No. 1 collar 401. A mounting ring 405 is fixedly connected to one end of the outer side of each connecting rod 402. A No. 2 rotating shaft 403 is rotatably mounted in each mounting ring 405. A slider 416 is fixedly connected to the upper and lower ends of each No. 2 rotating shaft 403. The upper and lower sliders 416 are installed in the slide groove 415. The slide groove 415 is arranged above and below the inner wall of the No. 2 collar 13. A support wheel 404 is fixedly sleeved on the upper and lower ends of each No. 2 rotating shaft 403. Each support wheel 404 is fixedly sleeved on the upper and lower ends of each No. 2 rotating shaft 403. The wheel 404 is close to the inner wall of the No. 2 sleeve ring 13, and the lower surface of each connecting rod 402 is fixedly connected to an extension rod 406, and the lower end of each extension rod 406 is fixedly connected to a fixing ring 407, and the lower surface of each fixing ring 407 is fixedly connected to a plurality of evenly distributed extension brackets 408, and the inner side of each extension bracket 408 is fixedly connected to an inner filter plate 16, and the lower end of the inner filter plate 16 is fixedly connected to a base 409, and the base 409 is rotatably installed below the inner wall of the cleaning housing 1, and the outer side of the base 409 is fixedly connected to a driven gear ring 410, and the outer side of the driven gear ring 410 is connected to a plurality of evenly distributed transmission gears 411 through a tooth meshing engagement, and each transmission gear 41 1 is connected to the outer side with a matching gear ring 412 through a tooth meshing, and the matching gear ring 412 is fixedly connected to the inner wall of the cleaning housing 1. A filter element bracket 413 is fixedly connected to the upper surface of each transmission gear 411, and a filter element 414 is installed in each filter element bracket 413. The rotating shaft 11 is driven by the driving motor 3 to rotate. When the rotating shaft 11 rotates, the connecting rod 402 located in the second sleeve ring 13 can be driven to rotate. Since the slider 416 is installed in the slide groove 416, the rotation of the rotating shaft 11 can be limited. Then, the rotating shaft 11 is supported around by the supporting wheel 404, so as to limit the rotating shaft 11 and reduce its wear coefficient, and provide self-priming work. The efficiency then drives the impeller 18 to rotate. Since the inner filter plate 16 and the outer filter plate 15 are arranged on the outer side of the impeller 18 and the inner side of the cleaning shell 1, the impurities in the self-priming pump can be filtered to prevent the liquid outlet 8 and the liquid suction port 6 from being blocked. When the rotating shaft 11 rotates, the base 409 can be driven to rotate through the extension rod 406 and the extension bracket 408. The base 409 is equipped with a transmission gear 411 through the outer driven gear 410 and the matching gear ring 412, which can drive the transmission gear 411 to rotate itself and make a circular motion with the base 409 as the center, so that the impurities in the self-priming pump are filtered and removed through the filter element 414 on the upper surface of the transmission gear 411.

[0024] Working principle of the present invention:

[0025] When in use, the rotating shaft 11 is driven to rotate by the driving motor 3. When the rotating shaft 11 rotates, the connecting rod 402 can be driven to rotate in the second sleeve ring 13. Since the slider 416 is installed in the slide groove 416, the rotation of the rotating shaft 11 can be limited. Then, the rotating shaft 11 is supported around by the supporting wheel 404, so as to limit the rotating shaft 11 and reduce its wear coefficient, provide self-priming work efficiency, and then drive the impeller 18 to rotate. Since the inner filter plate 16 and the outer filter plate 16 are arranged on the outer side of the impeller 18 and the inner side of the cleaning housing 1 15 can filter impurities in the self-priming pump to prevent the liquid outlet 8 and the liquid suction port 6 from being blocked. When the rotating shaft 11 rotates, the base 409 can be driven to rotate through the extension rod 406 and the extension bracket 408. The base 409 is equipped with a transmission gear 411 through the outer driven gear 410 and the matching gear ring 412. The transmission gear 411 can drive the transmission gear 411 to rotate itself and make a circular motion with the base 409 as the center, so that the impurities in the self-priming pump are filtered and removed through the filter element 414 on the upper surface of the transmission gear 411.
