Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a water-cooled explosion-proof motor for woodworking. Background Art

[0002] Motors are commonly used energy conversion devices that convert electrical energy into mechanical energy and are used in various fields. Water-cooled explosion-proof woodworking motors are explosion-proof motors designed specifically for the woodworking industry. They have the basic functions of general motors, but they have special explosion-proof designs for dangerous factors such as flammable gases and dust that may exist in the woodworking environment, so as to avoid explosions and other dangerous situations caused by motor failures.

[0003] At the same time, the water-cooled design can cool the motor more effectively, ensuring its stable performance and reliability during long-term operation, and adapting to the high-intensity operation requirements during woodworking. This type of motor has high requirements and characteristics in terms of safety and heat dissipation performance;

[0004] In the prior art, the water-cooled explosion-proof woodworking motor is generally adjusted by adjusting the output power of the water pump to adjust the water cooling effect of the water-cooled explosion-proof woodworking motor. However, the heating conditions of different parts of the motor are inconsistent. The stator part heats more, followed by the rotor and the bearing part. Therefore, the conditions requiring heat dissipation are inconsistent. The heat dissipation effect is adjusted by adjusting the water pump power.

[0005] It is not possible to dissipate heat according to the heat generated in different parts of the motor, thus causing limitations.

[0006] To this end, we propose a water-cooled explosion-proof motor for woodworking. Summary of the invention

[0007] In view of the deficiencies of the prior art, the present invention provides a water-cooled explosion-proof woodworking motor, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0011] Preferably, a detection drive mechanism is provided in the shell; the detection drive mechanism detects the temperature of the shell, and drives the corresponding No. 2 water-cooling pipe and No. 4 water-cooling pipe to move according to the temperature of the shell, so that the movement path of the cooling water on the shell is increased.

[0012] Preferably, the detection drive mechanism includes a detection chamber, a memory spring, a detection block and a connecting rod; the detection chamber is opened in the outer shell, and the detection chamber is arranged near the corresponding No. 1 mounting groove and the No. 2 mounting groove; the memory spring is fixedly connected in the detection chamber; the detection block is slidably connected in the detection chamber, and is slidably and sealedly connected to the detection chamber; the connecting rod is fixedly connected to the detection block; an opening is opened on the outer shell; the opening connects the detection chamber with the corresponding No. 1 mounting groove and No. 2 mounting groove; the connecting rod passes through the opening and is connected to the corresponding No. 2 water-cooling pipe and No. 4 water-cooling pipe.

[0013] By arranging No. 1 water-cooling pipe, No. 2 water-cooling pipe, No. 3 water-cooling pipe and No. 4 water-cooling pipe in No. 1 installation groove and No. 2 installation groove, and then arranging a detection drive mechanism in the outer shell, the No. 2 water-cooling pipe and No. 4 water-cooling pipe are pushed according to the temperature, thereby improving the water cooling effect.

[0014] Preferably, sliding blocks are evenly installed in the No. 1 water-cooling tube and the No. 3 water-cooling tube; fin groups are symmetrically rotatably connected to the sliding blocks; the fin groups between two adjacent sliding blocks slide and cooperate with each other; pushing grooves are provided on the No. 1 water-cooling tube and the No. 3 water-cooling tube; a pushing rod is slidably connected in the pushing groove; a pushing block is fixedly connected to the pushing rod; the pushing block extends out of the corresponding No. 1 water-cooling tube and the No. 3 water-cooling tube and slides and cooperates with each other.

[0015] Preferably, sliding grooves are evenly opened in the No. 1 water-cooling tube and the No. 3 water-cooling tube; the sliding blocks are slidably connected in the sliding grooves at intervals, and the remaining sliding blocks are fixedly connected to the corresponding No. 1 water-cooling tube and the No. 3 water-cooling tube; a sliding spring is fixedly connected between the sliding block and the sliding groove.

[0032] In the present invention, a detection drive mechanism is provided in the shell 1; the detection drive mechanism detects the temperature of the shell 1, and drives the corresponding No. 2 water cooling pipe 22 and No. 4 water cooling pipe 32 to move according to the temperature of the shell 1, so that the movement path of the cooling water on the shell 1 is increased.

[0033] Refer to the instruction manual Figure 6 In the present invention, the detection drive mechanism includes a detection chamber 41, a memory spring 6, a detection block 43 and a connecting rod 44; the detection chamber 41 is opened in the shell 1, and the detection chamber 41 is arranged near the corresponding No. 1 mounting groove 2 and No. 2 mounting groove 3; the memory spring 6 is fixedly connected in the detection chamber 41; the detection block 43 is slidably connected in the detection chamber 41, and is slidably and sealedly connected to the detection chamber 41; the connecting rod 44 is fixedly connected to the detection block 43; an opening 45 is opened on the shell 1; the opening 45 connects the detection chamber 41 with the corresponding No. 1 mounting groove 2 and No. 2 mounting groove 3; the connecting rod 44 passes through the opening 45 and is connected with the corresponding No. 2 water-cooling pipe 22 and No. 4 water-cooling pipe 32.

[0034] When the motor of the present invention is in use, both ends of the two No. 1 water cooling pipes 21 and the two No. 3 water cooling pipes 31 in the No. 1 installation slot 2 and the No. 2 installation slot 3 are connected to the external water pump, so that the cooling water enters the No. 1 water cooling pipe 21 and the No. 2 water cooling pipe 22 and then flows back from another No. 1 water cooling pipe 21; the cooling water enters the No. 3 water cooling pipe 31 and the No. 4 water cooling pipe 32 and then flows back from another No. 3 water cooling pipe 31, so that the cooling water cools the motor;

Since half of the sliding blocks 51 are fixedly connected to the corresponding No. 1 water-cooling tube 21 and No. 3 water-cooling tube 31 at intervals, the sliding block 51 slidably connected in the sliding groove 5 moves with the corresponding fin group 52, so that the fin groups 52 slidably connected to each other slide, so that the fin group 52 is bent in the corresponding No. 1 water-cooling tube 21 and No. 3 water-cooling tube 31, thereby slowing down the water flow rate and increasing the heat exchange between the fin group 52 made of metal, so that the water cooling effect is increased.
