[0002] Explosion-proof high-voltage water-cooled motors are important power equipment in coal mines. They use water cooling to dissipate heat from the inside of the motor to prevent the motor from exploding due to its internal high temperature and ensure the safe use of the motor.

[0003] During water cooling, the water tank, water pump and water cooler are connected by pipes to ensure that the cooling water flows in a closed channel. The water pump transports the cooling water to the water cooler inside the motor through the pipe. The water cooler contacts the components that need to dissipate heat, absorbs their heat, and then takes the heat away through the cooling water. Since the cooling water contains certain impurities, the internal channels of the water cooler need to be cleaned regularly during daily use to avoid the accumulation of more impurities inside and affecting the cooling and heat dissipation effect. When cleaning the water cooler, it is necessary to install and disassemble the water cooler. When installing and disassembling the water cooler, it is necessary not only to fix and disassemble the water cooler itself, but also to connect and separate it from the pipe, which makes the installation and disassembly operation more troublesome and cannot be installed and disassembled conveniently, which is convenient for the staff and improves the work efficiency of water cooler maintenance.

[0040] Before the sealing plate 4 moves down, the pushing top plate strip 91 is inserted into the moving groove 12.

[0041] A method for using an electric motor includes the following steps: Step 1: Positioning of the water cooler 2: Insert the contact pedestal 21 on the water cooler 2 into the limit carrier frame 44 for positioning: Step 2: Moving down of the sealing plate 4: Start the hydraulic rod member 15 to drive the sealing plate 4 to move down to close the installation opening 11, and at the same time drive the water cooler 2 to the installation position; Step 3: Fixing of the water cooler 2: Push the carrier plate 3 to drive the moving plate member 5 to move, so that the support strip plate 92 is inserted into the support cavity 22 to realize the fixed installation of the water cooler 2; Step 4: Connection between the water cooler 2 and the pipeline: The bearing plate frame 9 pushes the moving sleeve body 26 to move to realize the connection between the water cooler 2 and the water inlet pipe 16 and the water outlet pipe 17.

[0042] When installing the water cooler 2, insert its contact pedestal 21 into the limit carrier frame 44, support it through the bearing bottom plate 72 to position the water cooler 2, and then start the hydraulic rod 15 to drive the push plate 3 to move. As the push plate 3 moves, under the action of the downward pull channel 33, it will drive the sealing plate 4 to move downward, and finally cover the installation opening 11. As the sealing plate 4 moves downward, it will drive the water cooler 2 to move to the installation position and contact the heat dissipation part. As the push plate 3 moves, it will contact the moving plate member 5. Thus, under the action of the push plate 3, it will push the moving plate member 5 to move, and then under the action of the first hinge rod 54, it will pull the bearing plate member 6 to move downward relative to the sealing plate 4. As the bearing plate member 6 moves downward, under the action of the second hinge rod 63, it will push the bearing bar 7 to move away from the limit carrier frame 44. As the bearing bar 7 moves, it will also drive the hollow plate bar 8 to move synchronously with it. As the hollow plate bar 8 moves, under the action of the third hinge rod 83, it will also drive the hollow plate bar 8 to move along the bearing bar 7. Thus, driven by the hollow plate bar 8, the bearing plate frame 9 will move, and further make the support strip plate 92 on the bearing plate frame 9 inserted into the support cavity 22 to support and fix the water cooler 2. When the water cooler 2 moves down to the installation position, at this time the bearing bottom plate 72 is separated from the water cooler 2, the sealing plate 4 covers the installation opening 11, and the driving connecting column 42 is inserted into the holding channel 32. Thus, as the push plate 3 continues to move, the push top strip 91 will contact the movable plate member 272, and then push the movable plate member 272 to move, drive the movable sleeve 26 to move, so that the first insertion tube 28 on the movable sleeve 26 is inserted into the water inlet pipe 16, and the second insertion tube 29 is inserted into the water outlet pipe 17 to form a closed loop, completing the installation of the water cooler 2. The operation is simple, convenient and fast. When the water cooler 2 needs to be disassembled, just start the hydraulic rod 15 to drive the sealing plate 4 to move upward, and the unlocking of the water cooler 2 can be realized, and it can be quickly removed for convenient maintenance.
