[0002] An explosion-proof motor is a motor that can be used in flammable and explosive places and does not generate electric sparks during operation. The energy-saving explosion-proof motor is an innovative motor product that combines high efficiency, energy saving, and explosion-proof safety. It uses advanced technology and materials to provide higher energy efficiency and lower energy consumption while maintaining excellent safety performance. Compared with traditional explosion-proof motors, it can produce greater power output with less energy input, which not only reduces energy consumption and reduces pressure on natural resources, but also reduces energy expenses, bringing substantial economic benefits to enterprises.

[0003] The prior art discloses some invention patents in the field of explosion-proof motor technology, among which the invention patent with publication number CN115714498B discloses a shell water cooling device for an explosion-proof motor, including an explosion-proof shell and a water cooling module, wherein the explosion-proof shell is located on one side of the water cooling module, a sealing plate is fixedly connected to one end of the explosion-proof shell, an external joint is fixedly connected to the top surface of the explosion-proof shell, a water cooling groove is provided on the inner side of the explosion-proof shell, a partition is fixedly connected to the middle part of the inner side of the water cooling groove, two connecting valves are fixedly connected to the top surface of the explosion-proof shell, the two connecting valves are symmetrically arranged with the partition as the symmetry center, and the connecting valve is connected to the inner side of the water cooling groove. The technical solution injects internal circulating water into the water through a transmission pipe through the water cooling module. In the cold tank, with the setting of the partition, the liquid is allowed to fill the water cooling tank, and then circulates from the second transmission pipe to the water cooling module to fill the water cooling tank with liquid. The heat exchange effect of the water flow is much higher than the heat dissipation of the air flow, which ensures that the motor parts work at a suitable temperature, thereby effectively improving the service life of the servo motor. This technical solution still has some shortcomings in the process of application. Regardless of water cooling or air cooling, its driving source is a water pump. When the water pump is powered on, it will generate noise. In order to ensure accurate control, the explosion-proof servo motor will receive multiple signal pulses every millisecond, which affects the stability of the explosion-proof motor. When the water pump is powered on, it will generate a corresponding magnetic field, which will then generate corresponding electromagnetic interference, affecting the explosion-proof motor from receiving electrical signals.

[0004] Based on this, the present invention designs a shell water cooling device and method for an explosion-proof motor to solve the above problems. Summary of the invention

[0024] A method for water cooling the shell of an explosion-proof motor comprises the following steps:

[0025] When the explosion-proof motor is started, the signal pulse light is transmitted not only toward the built-in control chip of the explosion-proof motor, but also toward the heat dissipation system. Specifically, the signal pulse is filtered by a low-pass filter to obtain a low-frequency signal, and then the low-frequency signal is converted into a bass. The high amplitude characteristic of the bass is used as a driving medium to drive the heat dissipation system to dissipate heat for the explosion-proof motor. The driving source is used to provide power for the flow of the cooling medium. Under the action of the driving source, the diaphragm reciprocates in the horizontal direction in the assembly groove;

[0026] When the diaphragm bulges toward the driving pipe, the built-in ball valve of the one-way shutoff assembly A is separated from the bucket-shaped cover, and the ball valve slides on the inner side of the mesh panel through the directional shaft, and exerts pressure on the supporting spring to cause elastic deformation, and the coolant in the multiple heat dissipation fins A and the multiple heat dissipation fins B flows into the return main pipe through the multiple return branch pipes, and the coolant gathered in the return main pipe flows into the bridge pipe through the water cooling pipe C. When the diaphragm bulges away from the driving pipe, the built-in ball valve of the one-way shutoff assembly A is re-immersed in the bucket-shaped cover under the push of the return elastic force of the supporting spring. At this time, the one-way shutoff assembly A is in the shutoff state, and the one-way shutoff assembly A is in the shutoff state. The ball valve built into the interception component B is separated from the bucket-shaped cover, and the ball valve slides on the inner side of the mesh panel through the directional shaft and applies pressure to the support spring to cause elastic deformation. The coolant in the bridge pipe flows into the water-cooled self-cooling box through the water-cooling pipe D, and the coolant in the coolant self-cooling box flows into the branch main pipe A and the branch main pipe B respectively through the water-cooling pipe B. The coolant in the branch main pipe A flows into the multiple heat dissipation fins B respectively through the multiple branch branch pipes A, and the coolant in the branch main pipe B flows into the multiple heat dissipation fins A respectively through the multiple branch branch pipes B, forming a complete coolant circulation flow heat dissipation system;

[0027] The coolant flows from the cooling pipe D into the coolant self-cooling box and then flows to the water-cooling pipe B. During this process, the heat dissipation fins C can increase the contact area between the coolant and the outside world, thereby facilitating the improvement of the heat dissipation effect of the coolant during the flow process. The provision of multiple guide plates A and multiple guide plates B can extend the flow trajectory of the coolant in the coolant self-cooling box.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, when the explosion-proof motor is started, the signal pulse light is transmitted toward the built-in control chip of the explosion-proof motor in addition to being transmitted toward the heat dissipation system. Specifically, a low-pass filter is used to filter the signal pulse to obtain a low-frequency signal, and then the low-frequency signal is converted to obtain a bass. The high amplitude characteristic of the bass is used as a driving medium to drive the heat dissipation system to perform heat dissipation treatment on the explosion-proof motor. The driving source is used to provide power for the flow of the cooling medium to form a complete coolant circulation flow heat dissipation system. On the one hand, since the heat dissipation system has no other driving medium except the bass, the heat dissipation system does not generate other sounds except the bass. On the other hand, the entire heat dissipation system has no other electronic components except the low-pass filter, and the low-pass filter is used to filter the frequency of the electrical signal and will not generate a magnetic field that interferes with the electrical signal. Therefore, the entire heat dissipation system will not generate a magnetic field that interferes with the electrical signal.

[0030] 2. In the present invention, the coolant flows from the cooling pipe D into the coolant self-cooling box and then flows to the water-cooling pipe B. During this process, the heat dissipation fins C can increase the contact area between the coolant and the outside world, thereby facilitating the improvement of the heat dissipation effect of the coolant during the flow process. The provision of multiple guide plates A and multiple guide plates B can extend the flow trajectory of the coolant in the coolant self-cooling box, thereby facilitating the improvement of the self-cooling effect of the coolant.
