Description

Technical Field

[0001] The utility model relates to a mobile equipment for emergency drainage and fire fighting water supply, in particular to a self-powered mobile drainage system. Background Art

[0002] At present, traditional drainage equipment generally uses electric submersible pumps driven by motors. When dealing with emergencies such as urban waterlogging, water accumulation in underground garages, and emergency water supply for firefighting, it is difficult to connect to the mains and there is a safety risk of electric shock. It has problems such as complex operation, slow response, and poor mobility. Although some submersible pumps are installed on moving motor vehicles, when in use, the motor vehicle body must be kept away from the wading area to avoid accidents. Therefore, the submersible pump still needs to be removed from the motor vehicle body and moved to the wading area for operation, and the submersible pump is also difficult to quickly install and fix according to different specific environments. Utility Model Content

The system can be moved to dangerous areas and drive a submersible pump through its own power without being connected to the mains, thereby achieving fast, efficient and flexible emergency drainage and water supply.

The crawler-type traveling device comprises an active sprocket and a passive sprocket arranged at the bottom of the vehicle body, a crawler chain surrounding the active sprocket and the passive sprocket, and a sprocket hydraulic motor for driving the active sprocket to rotate. The submersible pump is a hydraulically driven hydraulic submersible diagonal flow pump with a water pump hydraulic motor. The engine drives an oil pump in the hydraulic system, and the oil pump provides hydraulic oil to the sprocket hydraulic motor and the water pump hydraulic motor to drive the sprocket hydraulic motor and the water pump hydraulic motor.

[0005] In the above-mentioned mobile drainage system, rubber blocks are fixed on the outer surfaces of the chain links hinged to each other in the crawler chain.

[0006] The above-mentioned mobile drainage system uses a Cummins QSB5.9 series engine with a rated power of 159 / 164kW and a speed of 1500 / 2200r / min. It adopts a closed circulating water cooling system and an industrial silencer.

[0007] The above mobile drainage system has two hydraulic submersible diagonal flow pumps with flow rates of 800m 3 / h and 1200m 3 / h, with lifts of 16m and 10m respectively.

[0008] The above-mentioned mobile drainage system also includes a control system for controlling the operation of the engine and hydraulic system. The control system includes a PLC, a display, and a control mechanism that can remotely and / or manually adjust and control the engine speed and oil pump oil pressure.

[0009] The above-mentioned mobile drainage system also includes a special-shaped articulated connecting rod arm, which includes a rocker arm, a driving rod, a support rod, and a follower rod. The lower end of the rocker arm is hinged on the vehicle body, and the two ends of the follower rod are respectively hinged to the front end of the driving rod and the front end of the support rod, the rear end of the support rod is hinged to the upper end of the rocker arm, the middle part of the rocker arm is hinged to the middle part of the driving rod, and the rear end of the driving rod is hinged to a driving device arranged on the vehicle body and can move forward and backward relative to the vehicle body; the submersible pump is fixed on the support rod.

[0010] In the above-mentioned mobile drainage system, the hinged connection between the lower end of the swing arm and the vehicle body is lower than the hinged connection between the rear end of the driving rod and the driving device.

[0011] The driving device of the above-mentioned mobile drainage system is an oil cylinder or an air cylinder, the cylinder body of the oil cylinder or the air cylinder is fixed on the vehicle body, and the rear end of the driving rod is hinged to the piston rod of the oil cylinder or the air cylinder.

[0012] The above-mentioned mobile drainage system has two special-shaped hinged connecting rod arms, which are symmetrically arranged on the left and right sides of the vehicle body, and each support rod is connected to a submersible pump.

[0013] In the above-mentioned mobile drainage system, the lower ends of the two swing arms are hinged to the two ends of a pivot, and the pivot is fixed on the vehicle body.

[0014] In the above-mentioned mobile drainage system, a bracket is fixedly connected between the two bracket rods near the front ends of the bracket rods, and two submersible pumps are fixed on the bracket.

[0015] In the above-mentioned mobile drainage system, a reinforcement rod is fixedly connected between the two driving rods, and a stabilizing rod is fixedly connected between the two support rods.

[0016] Beneficial effects of the utility model:

[0017] The utility model adopts a crawler walking device, which can drive the submersible pump to move to the vicinity of the water area to carry out water intake operations. At the same time, it adopts its own engine and hydraulic system to drive the vehicle body to move on its own and provide power for the hydraulic submersible diagonal flow pump. The system has a high drainage flow and high head, and can efficiently carry out drainage and water supply operations in various complex environments.

[0018] Rubber blocks are set on the track chain to adapt to different terrain conditions, increase friction with the ground and improve the maximum climbing angle.

[0019] The driving device moves forward and backward, and the rocker arm swings forward and backward. At the same time, the rear end of the driving rod moves forward and backward, and the hinge between the driving rod and the rocker arm rotates around the lower end of the rocker arm. The spatial position of the driving rod is changed, and the positions of the support rod and the follower rod are changed. The submersible pump fixed on the support rod can move forward and backward, up and down, and continuously change its operating position, thereby expanding the operating range of the submersible pump and making the mobile drainage system adapt to complex terrain. At the same time, the submersible pump can be maintained in this state at different positions, and the operating stability and safety are improved.

[0020] The hinge between the lower end of the swing arm and the vehicle body is lower than the hinge between the rear end of the driving rod and the driving device. At this time, the driving device drives the rear end of the driving rod to move forward, and the upper end of the swing arm moves forward, which can drive the submersible pump forward. As the rear end of the driving rod continues to move forward, the submersible pump can move downward. The submersible pump can perform drainage operations efficiently and stably in a low environment.

[0021] The special-shaped articulated connecting rod arm expands the horizontal operating range of the drainage equipment, and the water absorption depth can reach below the ground, effectively avoiding the influence of the eddy current area on the contact of the walking device such as the crawler track with the ground, ensuring the operation stability on soft ground.
