Description

Technical Field

[0001] The utility model relates to the field of drainage equipment, and particularly to a lifting mobile pumping station. Background Art

[0002] Mobile pumping stations are mainly used for drainage projects in explosion - prone areas and where the water contains sediment. For example, drainage projects in various mine environments, tunnels, sand cleaning, disaster relief, urban engineering and other scenarios.

[0003] The Chinese patent application with publication number CN113586142A discloses a mobile submersible pump station for mine emergency rescue and drainage. The mobile submersible pump station includes a crawler chassis; a submersible electric pump disposed in the middle of the crawler chassis; a lifting platform disposed above the submersible electric pump; a lifting control device connected to the lifting platform for adjusting the height of the lifting platform based on the water level to keep the lifting platform always above the water surface. An explosion - proof electric control box, a hydraulic station, an explosion - proof motor and a hydraulic pump are arranged on the lifting platform. The explosion - proof motor is used to drive the hydraulic pump, and the hydraulic pump serves as the pressure oil source of the hydraulic station. The hydraulic station provides hydraulic power for the telescoping of the platform lifting cylinder and the traveling of the crawler chassis. However, the submersible electric pump of this mobile submersible pump station is relatively fixed to the crawler chassis and cannot adjust the distance between the submersible electric pump and the ground according to the terrain water level.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] In order to improve or solve the technical problem that in the prior art, the submersible electric pump is relatively fixed to the crawler chassis and cannot adjust the distance between the submersible electric pump and the ground according to the terrain water level, the utility model provides a lifting mobile pumping station. The lifting mobile pumping station includes: a frame; a water pump; a lifting structure arranged between the frame and the water pump and configured to drive the water pump to lift relative to the frame; and a guiding structure arranged between the frame and the water pump and configured to define the moving direction of the water pump.

[0006] In the lift-type mobile pumping station of the present utility model, it includes a vehicle frame, a water pump, a lifting structure and a guiding structure. Among them, the vehicle frame is used to install various components, and the water pump is used to pump out accumulated water. The lifting structure is arranged between the vehicle frame and the water pump and is used to drive the water pump to lift, so as to adjust the position of the water pump relative to the ground according to the height of the terrain water level, facilitating the water pump to pump out accumulated water and preventing the water pump from being damaged. The guiding structure is arranged between the vehicle frame and the water pump and is used to guide the lifting of the water pump to prevent the water pump from tilting during the lifting process; at the same time, the guiding structure can also guide the water pump during the operation of the water pump to prevent the water pump from tilting. Through the above settings, the lift-type mobile pumping station of the present utility model can conveniently adjust the lifting of the water pump by setting the lifting structure and the guiding structure, so as to adjust the position of the water pump relative to the ground according to the height of the terrain water level, facilitating the water pump to pump out accumulated water and preventing the water pump from being damaged.

[0007] In a preferred technical solution of the above lift-type mobile pumping station, the guiding structure includes a tray connected to the water pump, a guiding rod installed on the tray, and a guiding sleeve that mates with the guiding rod and is installed on the vehicle frame. Through the above settings, the tray can provide a stable support and connection foundation for the water pump, and the cooperation of the guiding rod and the guiding sleeve can provide precise guidance for the lifting of the water pump.

[0008] In a preferred technical solution of the above lift-type mobile pumping station, the water pump is connected to a water outlet pipe, and a silent check valve is arranged between the water pump and the water outlet pipe. Through the above settings, the silent check valve can prevent the backflow of accumulated water.

[0009] In a preferred technical solution of the above lift-type mobile pumping station, there are two water pumps, and the two water pumps are controlled separately and are both connected to the water outlet pipe. Through the above settings, the two water pumps are controlled separately, and the water pumps can be operated individually or both water pumps can be turned on simultaneously according to actual needs. When both water pumps are turned on simultaneously, the lift remains unchanged and the flow rate increases.

[0010] In a preferred technical solution of the above lift-type mobile pumping station, an upper bracket is fixed on the circumferential outer side of the water pump, one end of the lifting structure is connected to the vehicle frame, and the other end is connected to the upper bracket. Through the above settings, the arrangement of the upper bracket facilitates the connection between the water pump and the lifting structure.

[0011] In a preferred technical solution of the above lift-type mobile pumping station, the lifting structure is a hydraulic cylinder.

[0012] In a preferred technical solution of the above lift-type mobile pumping station, the vehicle frame includes an installation part connected to the lifting structure and a traction part connected to the installation part; a steering front wheel is arranged below the traction part, and a rear wheel is installed on the installation part. Through the above settings, the arrangement of the steering front wheel and the rear wheel facilitates the vehicle frame to move to the working location.

[0013] In the preferred technical solution of the above-mentioned lifting mobile pumping station, a towing frame is provided on the towing part. Through the above arrangement, the layout of the towing frame facilitates the connection of the towing part to an external towing device, thereby driving the vehicle frame to move.

[0014] In the preferred technical solution of the above-mentioned lifting mobile pumping station, the vehicle frame further includes a connecting part connecting the towing part and the installation part, and the horizontal height of the towing part is greater than the horizontal height of the installation part. Through the above arrangement, the horizontal height of the towing part being greater than that of the installation part enables devices such as the hydraulic station, hydraulic pump, and electric control box to be arranged on the towing part, avoiding the above structures from getting waded.
