[0001] The utility model relates to mobile drainage equipment with a submersible pump capable of being raised and lowered, in particular to mobile drainage equipment with a special-shaped hinged connecting rod arm, which is suitable for scenes such as emergency drainage and fire-fighting water supply. Background Art

[0002] The existing mobile drainage equipment has a relatively fixed position of its submersible pump. When faced with complex terrain and low environments, there are usually problems such as limited up and down movement of the submersible pump, poor stability and severe eddy current influence, resulting in low drainage efficiency and poor operational safety. Utility Model Content

[0003] The purpose of the utility model is to provide a mobile drainage equipment with a special-shaped articulated connecting rod arm, which can effectively expand the operating range of the submersible pump, improve the operation stability and safety, and can efficiently and stably perform drainage operations in complex terrain and low environments.

[0004] The utility model discloses a mobile drainage device with a special-shaped articulated connecting rod arm, which comprises a vehicle body, a walking device and a submersible pump. The special-shaped articulated connecting rod arm comprises 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, 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.

[0005] In the above-mentioned mobile drainage equipment, the submersible pump is fixed on the support rod near the front end of the support rod.

[0006] In the above-mentioned mobile drainage equipment, 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.

[0007] The driving device of the above-mentioned mobile drainage equipment 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.

[0008] The above-mentioned mobile drainage equipment 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.

[0009] In the above-mentioned mobile drainage equipment, 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.

[0010] The above-mentioned mobile drainage equipment has a bracket fixedly connected between the two bracket rods near the front ends of the bracket rods, and two submersible pumps are fixed on the bracket.

[0011] In the above-mentioned mobile drainage equipment, a reinforcement rod is fixedly connected between the two driving rods, and a stabilizing rod is fixedly connected between the two support rods.

[0012] The beneficial effects of the utility model are as follows: the driving device moves forward and backward, the rocker arm swings forward and backward, and 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 changes, the positions of the support rod and the follower rod change, and the submersible pump fixed on the support rod can move forward and backward and up and down, continuously changing its operating position, thereby expanding the operating range of the submersible pump, allowing the mobile drainage equipment to adapt to complex terrain, and at the same time the submersible pump can be maintained in this state at different positions, thereby improving operating stability and safety.

[0013] 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.

[0014] Two special-shaped articulated connecting rod arms drive two submersible pumps. The two submersible pumps can work simultaneously or individually, which has better adaptability and further improves the drainage efficiency.

[0015] The bracket is fixedly connected between the two bracket rods, the reinforcement rod is fixedly connected between the two driving rods, and the stabilizing rod is fixedly connected between the two bracket rods, so that the entire special-shaped articulated connecting rod arm structure is more stable.

[0016] 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.
