[0022] The sewage pump is a common power equipment in the sewage treatment process, such as the vertical sewage pump (hereinafter referred to as vertical pump). If the pump is in the shallow water area when working, even if the water intake of the pump is less, it may cause the problem of dregs gathering and pump body overheating, which seriously affects the normal use of the sewage pump. Therefore, the shallow water protection needs to be set during the use of the pump. In the prior art, the control system of the pump is usually improved to improve the protection of the pump. However, when the control system is disturbed by the external environment, it will not react quickly. Therefore, the utility model will improve the mechanical mechanism to improve the shallow water protection function of the pump and ensure the safety of the pump.

[0023] The scheme of the utility model will be described in detail in conjunction with the drawings as follows:

[0024] The sewage pump shallow water protection system comprises a detection unit, a control unit and an adjusting unit, the detection unit is electrically connected with the control unit, the control unit is signal connected with the adjusting unit, the adjusting unit comprises a mounting seat 1, a connecting pipe 2 used for butt joint with a vertical pump body, a valve lock mechanism, the valve lock mechanism comprises a first valve lock 3 and a second valve lock 4, butt joint flanges and the first valve lock 3 are arranged at high and low pipe openings of the connecting pipe 2 respectively, a suction pipe 7 is vertically arranged on a pipe body of the connecting pipe 2, and a pipe opening of the suction pipe 7 is provided with the second valve lock 4, the mounting seat 1 comprises a double-layer π-shaped circular table support, a through hole is arranged on a circular table of the circular table support, the connecting pipe 2 passes through the through hole and is connected with the circular table support, the valve lock mechanism comprises a driving part, a sealing cover 5 and a sealing flange 6, one end of the sealing flange 6 is connected with a pipe opening of the connecting pipe 2 or a pipe opening of the suction pipe 7, the other end is used for being sealingly connected with the sealing cover 5, and the driving part controls the sealing cover 5 to rotate in a sealing plane of the sealing cover 5 to control the first valve lock 3 and the second valve lock 4 to open and close.

[0025] As described above, in the utility model, the detection unit obtains the detection signal, and it is judged whether the vertical pump is in or close to the shallow water protection state, if yes, the adjusting unit is controlled to act by the control unit to change the position of the suction inlet of the vertical pump, the suction inlet is changed from the relatively high suction pipe 7 to the relatively low connecting pipe 2, that is, the high suction inlet is switched to the low suction inlet, so that the vertical pump continues to work at the shallow water level, and when working at the shallow water level approaches the dangerous water level, the vertical pump body is controlled to stop working.

[0026] As shown in Figure 1 , the upper end of the connecting pipe 2 is used for butt joint with the pump body of the vertical pump through the butt joint flange, the connecting pipe 2 is erected in the mounting seat 1 of the double-layer circular table structure, the middle upper part of the connecting pipe 2 is provided with the suction pipe 7, the suction pipe 7 is the high suction inlet of the vertical pump, and the bottom end of the connecting pipe 2 is the low suction inlet of the vertical pump. The mounting seat 1 is used for providing the space for the flow of sewage when the bottom end of the connecting pipe 2 is used as the suction inlet, adopts the π-shaped circular table support structure, so that the conditions of supporting the vertical pump are met, and the hindrance to the sewage is reduced.

[0027] In addition, in the utility model, the second valve lock 4 and the first valve lock 3 are arranged at the high suction inlet and the low suction inlet respectively, if it is needed to switch to the low suction inlet, the first valve lock 3 at the low suction inlet is controlled to open, and the second valve lock 4 at the high suction inlet is controlled to close, so that the sewage is sucked from the pipe opening of the connecting pipe 2 where the low suction inlet is located.

[0028] Specifically, as shown in Figure 2 andFigure 3 As shown, one end of the sealing flange 6 is connected to the inlet of the connecting pipe 2 or the inlet of the suction pipe 7, and the other end is used for a sealing connection with the sealing cover 5. The aforementioned drive unit includes: a sealing pump, an electromagnetic relay, an electromagnetic ring 8, a connecting shaft, and a motor. The connecting shaft passes through the edges of the sealing flange 6 and the sealing cover 5. The motor is driven by the connecting shaft to control the rotation of the sealing cover 5 relative to the sealing flange 6, thereby opening or closing the corresponding suction inlet. Figure 3 As shown, the electromagnetic rings 8 are respectively disposed on the periphery of the sealing flange 6 and the sealing cover 5. The electromagnetic relay is electrically connected to the electromagnetic rings 8. The electromagnetic relay controls the generation or disconnection of magnetic attraction between the two electromagnetic rings 8. The electromagnetic rings 8 are used to improve the sealing performance between the sealing flange 6 and the sealing cover 5.

[0029] In addition, the sealing pump drives the sealing medium to fill the sealing groove on the sealing surface of the sealing cover 5. The sealing medium is an inflatable plastic hose, and the sealing pump is an air pump. When it is necessary to close the suction port, that is, to seal the sealing flange 6 and the sealing cover 5, first control the sealing cover 5 to rotate to the opposite side of the sealing flange 6, then control the electromagnetic rings 8 to magnetically attract each other. After the two end faces are magnetically attracted together, control the sealing pump to inflate the plastic hose embedded in the sealing groove, so that the sealing groove is filled with the plastic hose, thereby achieving a seal between the sealing cover 5 and the sealing flange 6.

The protective bracket 9 includes a top plate, a bottom plate, and a connecting column 91 disposed between the top plate and the bottom plate. The top plate and the bottom plate are used to connect to the outer shell of the vertical pump body. The top plate and the bottom plate are circular. A reinforcing ring is welded around the connecting column 91. The reinforcing ring is used to ensure that the connecting column is stable and does not deform, and its function is similar to that of the reinforcing rib in the injection molded part.

[0031] In some embodiments, the aforementioned detection unit is a level gauge, used to detect whether the water level has reached a shallow level or a dangerous level. Additionally, as... Figure 4 As shown, the control unit includes a signal receiving module, a data processing module, and a signal output module. The level gauge is signal-connected to the signal receiving module to acquire detected level information. The signal output module is signal-connected to the adjustment unit to control its operation. The data processing module is connected to both the signal receiving module and the signal output module to calculate and determine the level information, and uses the processing result to control the adjustment unit's operation. Additionally, a signal amplifier is included, connected to the signal receiving module, to increase the strength of the received signal, prevent misjudgments by the data processing module, and improve the detection accuracy and overall accuracy of the control system.

[0032] Finally, the sewage pump shallow water protection system provided by the utility model acquires detection signals through the detection unit, acquires whether the vertical pump is in or close to the state of shallow water protection, if yes, controls the adjusting unit to act through the control unit to change the position of the suction inlet of the vertical pump, changes from suction from the relatively high suction pipe 7 to suction from the relatively low connecting pipe 2, that is, changes from the high-position suction inlet to the low-position suction inlet, makes the vertical pump continue to work at the shallow water level, and controls the vertical pump body to stop working when working at the shallow water level approaches the dangerous water level. The optimized structure and control mode of the utility model not only meet the demand of the vertical pump shallow water protection, but also can continue to work in the shallow water area, further reduces the dangerous water level, and further expands the working water level interval of the vertical pump, and improves the practicability of the vertical pump.
