Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic auxiliary equipment, in particular to a heat preservation device for a hydraulic system in extremely cold weather. Background Art

[0002] A hydraulic system uses oil as a working medium, using the oil's pressure energy to drive hydraulic actuators. The hydraulic system operates by converting the mechanical energy generated by a power source (such as a motor or internal combustion engine) into pressure energy through an oil pump. This pressure energy is then converted into corresponding motion via various actuators, thereby achieving system control. Hydraulic transmission relies on a circuit consisting of a pump, oil pipes, and accumulators. The pressure energy of the power source, using liquid as the working medium, is converted through control valves into various forms that are easily adjustable and quantitatively controlled to meet different needs.

[0003] During the use of the hydraulic system, it is necessary to ensure that its internal temperature is at an appropriate temperature for operation. If some hydraulic systems encounter extremely cold weather during operation, the internal working efficiency of the hydraulic system will decrease, thereby affecting the working status of the corresponding components. Therefore, it is necessary to ensure that the internal temperature of the hydraulic system is maintained at an appropriate temperature to improve the thermal insulation performance of the hydraulic system.

By setting up a hydraulic auxiliary heat preservation device, a hybrid temperature control method combining water power and wind power is used to effectively improve the heat preservation efficiency of the hydraulic system, so as to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A heat preservation device for a hydraulic system in extremely cold weather comprises a shell and a hydraulic system protective shell arranged inside the shell, characterized in that a heat collecting plate is fixedly connected to the outer wall of the hydraulic system protective shell, a water flow trough is provided inside the heat collecting plate, a plurality of groups of heat conducting plates are fixedly connected to the inner wall of the water flow trough, a fixed plate is fixedly connected to the outside of the shell, a heat transfer plate is fixedly connected to the fixed plate, a cavity is provided inside the heat transfer plate, a temperature transfer fan is provided between the heat transfer plate and the heat collecting plate, a conduit is connected between the heat transfer plate and the heat collecting plate, and a water circulation mechanism is provided between the heat transfer plate and the heat collecting plate.

[0007] As a further solution of the present invention: the water circulation mechanism includes a water tank, a first water pipe is connected between the heat collecting plate and the water tank, a second water pipe is fixedly connected between the heat transfer plate and the water tank, and a water pump is provided on the first water pipe.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The hydraulic system insulation device uses a water pump to pump cooling water in the water tank into the heat collecting plate along the first water guide pipe. The water entering the heat collecting plate flows through the heat transfer plate and flows into the water tank through the second water guide pipe. The water flow insulates the hydraulic system casing. The setting of the heat conducting plate can fully absorb the water temperature and enhance the heat dissipation effect. At the same time, the setting of the heat transfer fan can directly insulate the hydraulic system casing, and can also insulate the heat collecting plate and heat transfer plate.

[0013] 2.
