DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the following will further describe the present application in combination with specific figures.

[0026] In order to make the technical means, creative features, purposes and effects achieved by the present application easy to understand, the following will further describe the present application in combination with specific figures. Figures 1-2The existing integrated pump station comprises a cylinder 1 provided with an inlet pipe 2 and an outlet pipe 3, the input end of the inlet pipe 2 is connected with an external urban drainage pipe (for example, to alleviate waterlogging), the output end of the inlet pipe 2 extends to the inside of the cylinder 1, the water discharged from the output end of the inlet pipe 2 firstly passes through the crushing grid 4 in the inside of the cylinder 1 to crush the larger impurities in the water, and then the impurities fall to the bottom of the cylinder 1 together with the water, in order to avoid that the water directly impacts the lifting water pump 5, the output end of the crushing grid 4 is further provided with a water baffle 16 for blocking the water flow from directly impacting the lifting water pump 5, the lifting water pump 5 is further arranged in the inside of the cylinder 1 to suck the water at the bottom of the cylinder 1, and the sucked water is discharged to the outside of the cylinder 1 through the outlet pipe 3, so as to alleviate the waterlogging in the low-lying areas in the city, and the existing integrated pump station has the problems of frequent blockage (blockage of the lifting water pump 5 or the outlet pipe 3) and foul smell around the integrated pump station in use, and the main problem causing the above-mentioned reasons is that when the integrated pump station processes the water, a large amount of heavy particle impurities are accumulated at the bottom and cannot be adsorbed by the lifting water pump 5 and discharged together with the water flow, so that the sludge is accumulated at the bottom, and the accumulation of the sludge is easy to cause corrosion of the lifting water pump 5 and the outlet pipe 3, and the sludge accumulation has many influences on the integrated pump station, such as the sludge accumulation causes the liquid level float 7 in the integrated pump station to move upwards, false alarm occurs, the lifting water pump 5 is in a long-term working state, and the sludge adheres to the liquid level float 7 to affect the accuracy.

[0027] In order to solve the above-mentioned problems, referring to Figures 3-6 The utility model provides a kind of anti-clogging automatic dredging device for integrated pump station, its integrated pump station and existing integrated pump station different point is, the existing lifting water pump 5 is suspended installation using installation support 9, lifting water pump 5 of suspended installation is apart from the bottom of cylinder 1 with certain spacing, so that enough space is left out for installing sludge lifting pump 12 and collecting plate 8 in the position of cylinder 1 close to lower part, specifically, collecting plate 8 is provided with discharge hole (one through hole, not marked in the figure) and the input end of sludge lifting pump 12 is connected, sludge accumulated in the inside of cylinder 1 is on collecting plate 8, when sludge lifting pump 12 works, sludge on collecting plate 8 enters the inside of sludge lifting pump 12 from discharge hole due to the double action of negative pressure and gravity, is simultaneously transported to the outside of cylinder 1 by sludge conveying pipe 13 of sludge lifting pump 12 output end, so as to realize the automatic dredging work in the inside of integrated pump station, compared with traditional manual cleaning is more convenient.

[0028] Further, referring to Figure 4 And Figure 5The inside of the barrel 1 is also provided with a sludge sensor 11 for monitoring the sludge thickness inside the barrel 1. The sludge sensor 11 can be installed inside the barrel 1 by using the boom 10. The barrel 1 is also provided with a controller 6. The output end of the sludge sensor 11 is connected to the input end of the controller 6 for providing the thickness signal of the sludge to the controller 6. Thus, when the sludge thickness on the sludge collecting plate 8 inside the barrel 1 reaches a certain degree, the controller 6 automatically controls the sludge lifting pump 12 to work, thereby realizing the cleaning of the sludge.

[0029] Further, referring to Figure 6 Since the sludge conveying pipe 13 will have sludge adhered to the inner wall after conveying the sludge, in order to avoid the odor generated by the sludge inside the sludge conveying pipe 13 from flowing back into the barrel 1, an electromagnetic valve 14 is also provided at the input end or the output end of the sludge lifting pump 12. The electromagnetic valve 14 can make the sludge conveying pipe 13 of the sludge lifting pump 12 in a closed state when the sludge lifting pump 12 is not working. Specifically, the installation position of the electromagnetic valve 14 can be the input end or the output end of the sludge lifting pump 12. Specifically, when the controller 6 monitors that the sludge thickness at the bottom of the barrel 1 is thick and reaches a set threshold, the controller 6 controls the sludge lifting pump 12 to work while controlling the electromagnetic valve 14 to open, thereby realizing the conveying of the sludge. When the conveying of the sludge is completed, the controller 6 controls the sludge lifting pump 12 to stop working while controlling the electromagnetic valve 14 to close.

[0030] Further, in order to ensure that the sludge can quickly fall to the discharging hole position of the sludge collecting plate 8, the sludge collecting plate 8 is set to be a conical shape. The discharging hole position is located at the center position of the sludge collecting plate 8, thereby realizing the quick sliding of the sludge to the discharging hole position and realizing the quick conveying.

[0031] Further referring to Figure 5 and Figure 7 In order to further promote the sludge on the sludge collecting plate 8 to slide to the discharging hole position and avoid the large adhesion of the sludge to the sludge collecting plate 8, a vibration motor 15 is also provided on the lower side wall of the sludge collecting plate 8. The vibration motor 15 can drive the sludge on the sludge collecting plate 8 to quickly slide. The operation of the vibration motor 15 is also controlled by the controller 6 for working during the conveying and cleaning of the sludge.

[0032] Further, the sludge sensor 11 can adopt an existing ultrasonic sludge interface instrument to realize the real-time monitoring of the sludge thickness. The ultrasonic sludge interface instrument utilizes the ultrasonic echo detection principle to calculate the thickness or interface position of the sludge by emitting ultrasonic waves and receiving the signals reflected from the surface of the sludge.

Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
