[0003] When protecting power equipment, a relay protection device is required. Among them, the "relay protection device" disclosed in the publication number "CN205195228U" has solved various technical drawbacks that it is extremely inconvenient for the operator to plug and unplug the completed wiring plug by going around to the back during maintenance of such relay protection devices.

[0004] However, there are still many defects in the actual use of relay protection devices with similar structures. For example, in the prior art, it is not easy to ensure the long-term load operation of the device. The long-term high-load operation of the device is likely to cause heat accumulation in the device, which is prone to short circuits and failures, reducing the stable operation effect of the device and also reducing the reliable operation effect of the device, and it is not convenient for the device to be popularized and used. Therefore, a microcomputer relay protection device for power equipment is proposed. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides a microcomputer relay protection device for power equipment to solve the above problems.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions: A microcomputer relay protection device for power equipment, including a box body, a relay protector is fixedly installed on the top of the box body, a driving mechanism for neutralizing the heat generated during the operation of the relay protector is fixedly installed outside the relay protector, and a wire management mechanism for managing the device cables is fixedly installed on one side of the box body;

[0009] Preferably, one side of the front of the box body is fixedly installed with a hinge, and a box door is fixedly installed on one side of the hinge.

[0010] Preferably, the outside of the relay protector is sleeved and installed with a mounting frame fixedly connected to one side of the bottom inside the box body, and a rubber spring is fixedly installed on one side of the bottom of the relay protector.

[0011] Preferably, a winding roller is rotatably installed inside the shaft bracket, a housing is fixedly installed on one side of the shaft bracket, a torsion spring is fixedly installed inside the housing, and a locking member is installed on the top of the shaft bracket by threading.

[0012] Preferably, a fixing plate is embedded and installed on the top of the box body, and heat dissipation grooves are equidistantly arranged inside the fixing plate.

[0014] Beneficial effects

[0015] The utility model provides a microcomputer relay protection device for power equipment. Compared with the prior art, the following beneficial effects are achieved:

[0016] 1. The running temperature of the relay protector is monitored in real time by the patch temperature sensor, and the intelligent control of the refrigeration component to energize and operate can be facilitated by cooperating with the controller. By the energization and operation of the refrigeration component, the cooling liquid stored inside the fixed box can be cooled. Then, the suction force is generated by the energization and operation of the delivery pump to suck the low-temperature cooling liquid, and the low-temperature cooling liquid is conveyed to the inside of the copper shell through the pipe fittings. The flowing cooling liquid can absorb the heat accumulated by the relay protector through the copper shell and the heat-absorbed cooling liquid is conveyed to the inside of the fixed box through the circulation pump for recycling, realizing the function of safety protection for the device, avoiding the problem that the device is prone to short circuit and failure due to the heat accumulation caused by the long-term high-load operation of the device, ensuring the stable effect of using the device, improving the reliable effect of using the device, and facilitating the popularization and use of the device.

[0017] 2. The device cable is pulled by the operator to connect with external equipment. The moving cable can drive the winding roller to rotate. The rotating winding roller can drive the torsion spring to undergo elastic deformation. The elastic force of the torsion spring can enable the device docking cable to be arranged orderly, and the length of the device docking cable can be fixed by the rotating locking part. When it is necessary to disconnect the device, the high deformation force of the torsion spring can drive the winding roller to rotate in the reverse direction. The reversely rotating winding roller can wind up the device docking cable, realizing the function of automatically arranging the cable of the device, avoiding the problem that the device docking cable is too long and prone to entanglement, increasing the convenience of using the device, and at the same time avoiding the problem that the entangled cable is prone to heat accumulation, which is convenient for the device to be popularized and used.
