Detailed Implementation

[0024] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] The invention will now be further described with reference to the accompanying drawings.

[0026] like Figures 1 to 3 To address the issue of equipment stability;

[0027] The pumping device is slidably connected inside the fixed base 11. Two fixed plates 101 are located inside the fixed base 11. Two sliders 102 are rotatably connected to both ends of each fixed plate 101. Multiple compression springs 103 are fixedly connected between the sliders 102 and the fixed base 11. Mounting holes are provided around the fixed base 11.

[0028] This invention provides a sewage pump with both dry and submersible operation modes. In dry operation, the pump body is fixed to a horizontal surface, and then the mounting holes on the fixing base 11 are used to fix the device to the plane. The fixing plate 101 inside the fixing base 11 supports the internal pumping device, thus stabilizing the device and preventing it from tipping over due to vibration during dry operation. In submersible operation, a lifting ring is provided above the pumping device, which is then used to place the pumping device in the sewage. Since sewage contains sediment, the pump body is more prone to tipping over when operating on it. Therefore, in this device, as the fixing plate 101 comes into contact with the sediment at the bottom of the sewage, the pumping device above, due to gravity... The pump continues to press down, causing the two fixed plates 101 to move downwards and insert into the sewage. This, in turn, moves the slider 102 downwards, compressing the spring 103. When the slider 102 moves below the fixed seat 11, the upper part of the fixed plate 101 has an inclined surface. When the pump continues to press down, the inclined surface can drive the fixed plate 101 to rotate, causing the lower part of the fixed plate 101 to be slightly squeezed upwards. This makes the sewage under the pump body more compact, further fixing the pump body to the surface of the sewage and increasing its stability. When the pump is removed from the sewage, the compressed spring 103 can drive the slider 102 to reset, causing the fixed plate 101 to move upwards and retract into the fixed seat 11.

[0029] like Figure 2 , Figure 4 and Figure 5 To prevent clogging when using submersible sewage pumps;

[0030] The first opening is located at the right end of the fixed base 11. The rotating plate 106 is rotatably connected inside the first opening. The upper and lower ends of the outer side of the first opening are respectively rotatably connected to a threaded rod 104. The push plate 105 is threadedly connected between the two threaded rods 104. The fixed base 11 is equipped with a cleaning motor. The output shaft of the cleaning motor is fixedly connected to one of the threaded rods 104. The two threaded rods 104 are connected by a belt.

[0031] In dry operation, the present invention connects the inlet and outlet pipes to the pumping device to achieve the effect of pumping sewage. In submersible operation, a sealing head is installed at the flange of the inlet pipe 13, so that the device itself can directly pump sewage during use. When the sewage pump is placed in the sewage, as the pumping device moves downward, it can press the inner side of the rotating plate 106, causing the rotating plate 106 to rotate and tilt. During the operation of the pumping device, the internal dirt can slide off through the rotating plate 106, while driving the cleaning motor to rotate, which in turn drives the threaded rod 104 to rotate, and the threaded rod drives the push plate 105 to move left and right, thereby preventing excessive dirt from accumulating on the rotating plate 106 and causing blockage.

[0032] like Figures 6 to 8 In order to achieve the purpose of pumping sewage;

[0033] The pumping device includes a sliding box 12 and a pressurizing box 16 fixed inside the sliding box 12. A valve 14 is fixed to both the left and right ends of the pressurizing box 16. An inlet pipe 13 is fixed to the right valve 14, and a flange is provided at the other end of the inlet pipe 13. An outlet pipe 15 is fixed to the left valve 14, and a flange is provided at the other end of the outlet pipe 15.

[0034] When the sewage pump is in dry operation, a water pipe is connected to each of the two flanges, allowing water to flow into the inlet pipe 13. Then, the pressurization tank 16 draws water into it. At this time, the right valve 14 is open and the left valve 14 is closed. Then, the pressurization tank 16 sends water into the outlet pipe 15. At this time, the left valve 14 opens and the right valve closes, thus achieving the purpose of pumping sewage. In submersible operation, the flange at the inlet pipe 13 is closed, and sewage directly enters the inlet pipe 13. The sewage pumping operation is carried out in the same way.

[0035] like Figure 8 In order to achieve the purpose of cleaning up the pollutants in the sewage;

[0036] A push screen 301 is slidably connected inside the water inlet pipe 13. A second opening is provided on the right side of the water inlet pipe 13. A filter screen is fixed between the water inlet pipe 13 and the right valve 14.

[0037] In submersible operation, as the pumping device moves downward, the inlet pipe 13 moves downward, aligning the second opening with the first opening. Wastewater can then directly enter the inlet pipe 13 through the second opening. The pusher screen 301 then reciprocates, filtering out internal contaminants before the water in the inlet pipe 13 enters the pressurization tank 16. Simultaneously, the filter screen at the right-end valve 14 further enhances the filtration effect. The contaminants filtered by the pusher screen 301 are then cleaned to both sides by the pusher plate 105, achieving the purpose of cleaning. In dry operation, the inlet pipe 13 is located above the fixed base 11, thus blocking the second opening. A filter screen should be installed at the flange of the inlet pipe 13 to prevent contaminants from entering. Similarly, the pusher screen 301 can isolate any small amount of contaminants that do enter the inlet pipe 13, preventing pump blockage.

[0038] like Figure 8 and Figure 12 To achieve the purpose of controlling the reciprocating movement of the net;

[0039] A first connecting rod 302 is fixedly connected to the push net 301, and a second connecting rod 303 is rotatably connected to the first connecting rod 302. An eccentric wheel 304 is rotatably connected to the other end of the second connecting rod 303.

[0040] A rotating shaft 202 is fixedly connected to the eccentric wheel 304. The rotating shaft 202 is rotatably connected to the sliding box 12. The output shaft of the motor 201 is connected to the rotating shaft 202 via a belt. The motor 201 is fixedly connected to the sliding box 12.

[0041] The drive motor 201 rotates, which in turn drives the rotating shaft 202 to rotate, which in turn drives the eccentric wheel 304 to rotate, which in turn causes the left end of the second connecting rod 304 to move left and right. At the same time, the two rotate relative to each other, which in turn causes the right end of the second connecting rod 304 to drive the first connecting rod 302 to move left and right, which in turn drives the push net 301 to move left and right, thereby achieving the purpose of controlling the reciprocating movement of the push net.

[0042] like Figure 9 and Figure 12 To increase the pumping capacity of the water pump;

[0043] The outlet pipe 15 is rotatably connected to a threaded bevel 501, and the threaded bevel 501 and the rotating shaft 202 are connected by a belt.

[0044] During the rotation of the drive motor 201, the rotating shaft 202 is driven to rotate, which in turn drives the threaded inclined surface 501 inside the water outlet pipe 15 to rotate, thereby conveying the internal sewage to the outlet. Since the present invention uses pressure to extract sewage, when the sewage is pumped upward during submersible use, the water pressure in the water outlet pipe will be too high, which will affect the pumping effect. Therefore, the threaded inclined surface 501 can provide some upward force, thereby increasing the pumping capacity of the water pump.

[0045] like Figure 10 In order to achieve the purpose of controlling the valve;

[0046] Each valve 14 has a track 401 fixed inside, and each track 401 has a small ball 402. Each valve 14 also has a rubber ring 403 fixed inside.

[0047] A pressure plate 601 is slidably connected inside the pressure box 16, and rubber strips are provided around the pressure plate 601.

[0048] The rubber ring 403 on the right valve 14 is fixed to the inlet pipe 13, and the rubber ring 403 in the left valve 14 is fixed to the pressure box 16. This causes the pressure plate 601 to move linearly, reducing the pressure in the pressure box 16. At this time, the ball 402 in the left valve 14 moves to the right along the track and moves to the rubber ring 403, squeezing the rubber ring 403 to close the left valve 14. Similarly, the ball 402 in the right valve moves away from the rubber ring 403, opening the right valve 14 and drawing water from the inlet pipe 13 into the pressure box 16. Similarly, when the pressure plate 601 moves downward, the right valve 14 closes and the left valve 14 opens, forcing water from the pressure box 16 into the outlet pipe 15, thus controlling the valve 14.

[0049] like Figure 10 and Figure 11 To achieve the purpose of controlling the reciprocating movement of the pressure plate;

[0050] A ring 602 is rotatably connected to the pressure plate 601, and a drive disk 603 is rotatably connected inside the ring 602. The eccentric position of the drive disk 603 is fixedly connected to the shaft of the motor 201.

[0051] When the control motor 201 rotates, it drives the drive disk 603 to rotate, which in turn makes it rotate relative to the ring 602. At the same time, it drives the ring 602 to move up and down, which in turn drives the pressure plate 601 to move up and down. During the up and down movement of the ring 602, there will always be a left and right offset, which causes the ring 602 and the pressure plate 601 to rotate relative to each other, thus avoiding jamming and achieving the purpose of controlling the reciprocating movement of the pressure plate 601.
