[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] The existing steel wire hose bracket at the pump outlet of the raw brine transfer pump on the pontoon is a T-shaped bracket, which is non-adjustable, and the contact surface between the support surface and the steel wire hose is small. During the production process, the steel wire hose is easily squeezed and deformed and ruptured and leaked at the support point, which increases the pipeline resistance, affecting both production efficiency and the sanitation of the working environment and the operating efficiency of the pump. When the liquid level in the pump pit rises, the pontoon may be tilted by the steel wire hose bracket, which poses a certain safety risk. In addition, because the steel wire hose bracket is a T-shaped fixed bracket and cannot be adjusted, it is extremely inconvenient to disassemble and align the steel wire hose, and the maintenance work is difficult and the maintenance cost is high, resulting in high production costs.

[0026] In order to solve the above problems, refer to Figures 1 to 4 As shown, the utility model provides a support structure, which includes: a mounting seat 10; a lifting mechanism 20, which is movably arranged on the mounting seat 10 along the vertical direction; a rotating mechanism 30, which is rotatably arranged on the lifting mechanism 20, and the rotating mechanism 30 includes a supporting structure and a stop structure, and the supporting structure and the stop structure enclose a receiving space for the wire hose 40 to pass through, and the supporting structure includes at least one first rolling member 31.

[0027] In this embodiment, a raw brine delivery pump is provided on the pontoon, one end of the steel wire hose 40 is connected to the raw brine delivery pump, and the other end of the steel wire hose 40 is connected to the liquid inlet pipeline of the salt field production workshop.

[0028] The lifting mechanism 20 can move in the vertical direction relative to the mounting seat 10, the rotating mechanism 30 can rotate 360° around itself relative to the lifting mechanism 20, the middle part of the steel hose 40 is placed in the accommodating space, at least one first rolling element 31 is located at the end of the steel hose 40 away from the raw brine delivery pump, and a rolling contact is formed between the bottom of the steel hose 40 and the first rolling element 31. Compared with the sliding contact, the rolling contact has smaller friction and can reduce the wear on the steel hose 40. When the pontoon rises and falls with the rise and fall of the liquid level in the pump pit, the lifting mechanism 20 rises or falls a certain height relative to the mounting seat 10, which can adjust the height of the steel hose 40, so that the steel hose 40 can adapt well to the change of the position of the pontoon caused by the change of the liquid level in the pump pit, and avoid the steel hose 40 from being squeezed, deformed, broken and leaked at the supporting point, thereby ensuring production efficiency and improving the safe operation efficiency of the raw brine delivery pump and the pontoon. In the process of the pontoon rising and falling with the rise and fall of the liquid level in the pump pit, the pontoon will inevitably rotate at a certain angle. The angle of the steel hose 40 is adjusted by the rotation of the rotating mechanism 30, so that the steel hose 40 can adapt well to the change of the angle of the pontoon caused by the change of the liquid level in the pump pit, solving the problem of disassembly and alignment of the steel hose 40, reducing the difficulty of maintenance work, reducing maintenance costs, and saving production costs. At the same time, due to the change in the height of the steel hose 40, the steel hose 40 will move along its laying direction in the accommodation space, and the steel hose 40 and the first rolling element 31 are in rolling contact, so that the steel hose 40 moves more smoothly along its laying direction. The support structure of the present application has the advantages of simple structure, flexible operation, and the ability to improve the safety performance of the raw brine delivery pump and the pontoon during operation.

[0029] See also Figures 1 to 4 As shown, in one embodiment of the present invention, along the axial direction of the steel wire hose 40, the height of the supporting structure gradually decreases from the middle to both ends.

When the pontoon rises and falls with the rise and fall of the liquid level in the pump pit, when the height of the steel hose 40 is adjusted by the lifting mechanism 20, the steel hose 40 will move along its laying direction in the accommodating space.
