Description

Technical Field

[0001] The utility model relates to the technical field of drainage pumps, in particular to a sand-proof drainage pump for high-speed rail projects. Background Art

[0002] In the construction of high-speed rail projects, especially during the ground leveling and subgrade filling stages, due to the influence of natural factors such as complex terrain or rainfall, waterlogging often occurs on the construction site. To ensure the construction progress and project quality, drainage is an essential link. At this time, engineering personnel usually use drainage pumps to effectively drain the accumulated water on the construction site.

[0003] Currently, in order to better handle the problem of sediment in the accumulated water, drainage pumps are usually equipped with filter nets in design and use to prevent sediment from entering the impeller of the drainage pump, thereby reducing the damage of sediment to the drainage pump. However, with the long-term use of the drainage pump, a large amount of sediment and debris will inevitably accumulate on the filter net. These accumulations will gradually block the filter net, requiring manual shutdown and consuming a lot of time for dredging and maintenance, thus reducing the work efficiency. Therefore, we have proposed a new type of sand-proof drainage pump for high-speed rail projects. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that with the long-term use of the drainage pump in the prior art, a large amount of sediment and debris will inevitably accumulate on the filter net, these accumulations will gradually block the filter net, requiring manual shutdown and consuming a lot of time for dredging and maintenance, reducing the work efficiency, and to propose a sand-proof drainage pump for high-speed rail projects.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A sand-proof drainage pump for high-speed rail projects, including a pump body, the input end of the pump body is fixedly communicated with a water inlet pipe, the end of the water inlet pipe is fixedly communicated with a first connecting pipe, both ends of the first connecting pipe are fixedly connected with a second connecting pipe through a flange, a second solenoid valve is arranged in a matching manner at a position close to the left side of the outer surface of the second connecting pipe, a first solenoid valve is arranged in a matching manner at a position close to the right side of the outer surface of the second connecting pipe, a mounting plate is fixedly installed at a position on the outer surface of the second connecting pipe to the right of the second solenoid valve, a motor is fixedly installed at the top of the mounting plate, the output end of the motor sequentially penetrates through the mounting plate and the outer surface of the second connecting pipe and extends into the second connecting pipe, and a circular filter plate is fixedly installed at the output end of the motor.

[0006] Furthermore, a fourth connecting pipe is fixedly connected between the ends of the two second connecting pipes through a flange, and a fifth connecting pipe is fixedly communicated with the outer surface of the fourth connecting pipe.

[0007] Further, a controller is provided on the outer surface of the pump, and a water flow sensor is provided on the outer surface of the water inlet pipe. The controller is electrically connected to the water flow sensor.

[0008] Further, the output end of the pump is fixedly communicated with a water outlet pipe, and the outer surface of the water outlet pipe is symmetrically and fixedly communicated with a sixth connecting pipe.

[0009] Further, a third connecting pipe is fixedly communicated with the outer surface of the second connecting pipe at a position to the left of the first solenoid valve, and a third solenoid valve is provided on the outer surface of the third connecting pipe.

[0010] Further, a seventh connecting pipe is fixedly connected between the ends of the third connecting pipe and the sixth connecting pipe through a flange.

[0011] Further, a drain pipe is fixedly communicated with the outer surface of the second connecting pipe at a position to the left of the mounting plate, and a fourth solenoid valve is provided on the outer surface of the drain pipe.

[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0013] 1. In the present utility model, by controlling the opening of the third solenoid valve on the corresponding side through the controller, the water flow in the water outlet pipe sequentially enters the second connecting pipe through the sixth connecting pipe, the seventh connecting pipe and the third connecting pipe on the corresponding side, so as to wash the sediment on the surface of the circular filter plate. At the same time, the motor is started to drive the circular filter plate to rotate, so as to change the angle of the circular filter plate, so that the circular filter plate no longer blocks the sediment. At the same time, by opening the fourth solenoid valve, the sediment and the water for washing the sediment can be discharged through the drain pipe. The overall automation degree is high, no manual intervention is required, and the overall working efficiency is improved.

[0014] 2. In the present utility model, when there is a large amount of sediment accumulated on the surface of the circular filter plate, the water flow rate will gradually decrease. The water flow sensor on the water inlet pipe can monitor the water flow rate in real time. When the water flow rate is less than the threshold set by the water flow sensor, the water flow sensor sends a signal to the controller, and the controller controls the valve on the second connecting pipe on the corresponding side to close. At the same time, the first solenoid valve and the second solenoid valve on the other side are opened, so as to change the water flow channel, so that the accumulated water flows through the second connecting pipe on the other side, so that the pump can work continuously without stopping for maintenance, and the working efficiency is improved.

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-4 shown, the present utility model provides a sand-proof drainage pump for high-speed rail projects, including a pump 1. The input end of the pump 1 is fixedly communicated with a water inlet pipe 2. The end of the water inlet pipe 2 is fixedly communicated with a first connecting pipe 21. Both ends of the first connecting pipe 21 are fixedly connected with a second connecting pipe 3 through flange plates. A second solenoid valve 34 is provided in a matching manner at a position near the left side of the outer surface of the second connecting pipe 3. A first solenoid valve 33 is provided in a matching manner at a position near the right side of the outer surface of the second connecting pipe 3. A mounting plate 4 is fixedly installed at a position on the outer surface of the second connecting pipe 3 to the right of the second solenoid valve 34. A motor 41 is fixedly installed on the top of the mounting plate 4. The output end of the motor 41 sequentially penetrates through the mounting plate 4 and the outer surface of the second connecting pipe 3 and extends into the second connecting pipe 3. A circular filter plate 42 is fixedly installed at the output end of the motor 41. The ends of the two second connecting pipes 3 are fixedly connected with a fourth connecting pipe 5 through flange plates. A fifth connecting pipe 51 is fixedly communicated with the outer surface of the fourth connecting pipe 5.

[0023] The effect achieved by the entire Embodiment 1 is that by starting the pump 1, the accumulated water is pumped into the fifth connecting pipe 51, and successively passes through the second connecting pipe 3, the first connecting pipe 21, and the water inlet pipe 2, and is discharged from the water outlet pipe 6, thereby achieving the function of drainage. When the accumulated water passes through the circular filter plate 42 in the second connecting pipe 3, the circular filter plate 42 can filter the sediment in the accumulated water. When there is a large amount of sediment accumulated on the surface of the circular filter plate 42, the water flow rate will gradually decrease, and the water flow sensor 22 on the water inlet pipe 2 can monitor the water flow rate in real time.

[0024] Embodiment 2, as Figures 1-4 shown, a controller 11 is provided on the outer surface of the pump 1, a water flow sensor 22 is provided on the outer surface of the water inlet pipe 2, the controller 11 is electrically connected to the water flow sensor 22, the output end of the pump 1 is fixedly communicated with a water outlet pipe 6, and symmetrically fixedly communicated with a sixth connecting pipe 61 on the outer surface of the water outlet pipe 6. A third connecting pipe 32 is fixedly communicated with the position on the outer surface of the second connecting pipe 3 to the left of the first solenoid valve 33. A third solenoid valve 35 is provided on the outer surface of the third connecting pipe 32. A seventh connecting pipe 7 is fixedly connected between the end of the third connecting pipe 32 and the sixth connecting pipe 61 through a flange. A drain pipe 31 is fixedly communicated with the position on the outer surface of the second connecting pipe 3 to the left of the mounting plate 4. A fourth solenoid valve 36 is provided on the outer surface of the drain pipe 31.

[0025] The effect achieved by the entire Embodiment 2 is that the water flow enters the second connecting pipe 3 through the corresponding sixth connecting pipe 61, seventh connecting pipe 7, and third connecting pipe 3, thereby flushing the sediment on the surface of the circular filter plate 42. At the same time, the motor 41 is started to drive the circular filter plate 42 to rotate, thereby changing the angle of the circular filter plate 42 so that the circular filter plate 42 no longer blocks the sediment. At the same time, by opening the fourth solenoid valve 36, the sediment and the water for flushing the sediment can be discharged through the drain pipe 31. The overall automation degree is high, without manual intervention, and the overall working efficiency is improved.

[0026] Working principle: When in use, it is connected to the fifth connecting pipe 51 through a hose. One end of the hose is placed in the accumulated water. By closing the first solenoid valve 33 and the second solenoid valve 34 on any one side of the second connecting pipe 3, and the other side is in an open state. By starting the pump 1, the accumulated water is pumped into the fifth connecting pipe 51, and then successively passes through the second connecting pipe 3, the first connecting pipe 21 and the water inlet pipe 2, and is discharged from the water outlet pipe 6, so as to achieve the function of drainage. When the accumulated water passes through the circular filter plate 42 in the second connecting pipe 3, the circular filter plate 42 can filter the sediment in the accumulated water. When there is more sediment accumulated on the surface of the circular filter plate 42, the water flow rate will gradually decrease. The water flow sensor 22 on the water inlet pipe 2 can monitor the water flow rate in real time. When the water flow rate is less than the threshold set by the water flow sensor 22, the water flow sensor 22 sends a signal to the controller 11, and the controller 11 controls the valve on the corresponding side of the second connecting pipe 3 to close. At the same time, the first solenoid valve 33 and the second solenoid valve 34 on the other side are opened, so as to change the water flow channel and make the accumulated water flow through the second connecting pipe 3 on the other side, so that the pump 1 can work continuously without shutdown maintenance, improving the work efficiency. At this time, since there is more sediment accumulated on the surface of the circular filter plate 42 inside the initial second connecting pipe 3, the controller 11 controls the corresponding third solenoid valve 35 to open. At this time, the water flow in the water outlet pipe 6 successively passes through the corresponding sixth connecting pipe 61, the seventh connecting pipe 7 and the third connecting pipe 32 and enters the second connecting pipe 3, so as to wash the sediment on the surface of the circular filter plate 42. At the same time, the motor 41 is started to drive the circular filter plate 42 to rotate, so as to change the angle of the circular filter plate 42 and make the circular filter plate 42 no longer block the sediment. At the same time, by opening the fourth solenoid valve 36, the sediment and the water for washing the sediment can be discharged through the drain pipe 31. The overall automation degree is high, without manual intervention, and the overall work efficiency is improved.

[0027] The above is only the preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
