Description

Technical Field

[0001] The present invention relates to the technical field of electric motors, and in particular to an explosion-proof high-pressure water-cooled electric motor for mining and a method for using the same. Background Art

[0002] Explosion-proof high-voltage water-cooled motors are important power equipment in coal mines. They dissipate heat from the inside of the motor through water cooling 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 through the pipe to the water cooler inside the motor. 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 water cooler needs to clean its internal channels 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, the water cooler needs to be installed and disassembled. When installing and disassembling, the water cooler not only needs to be fixed and disassembled itself, but also needs to be connected and separated 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 the water cooler maintenance.

[0065] Before the sealing plate 4 moves downward, the ejecting strip 91 is inserted into the moving groove 12 .

[0066] A method for using an electric motor comprises the following steps:

[0067] Step 1: Positioning the water cooler 2: Insert the contact base 21 on the water cooler 2 into the limiting frame 44 for positioning:

[0068] Step 2: Moving the sealing plate 4 downward: Activate the hydraulic rod 15 to drive the sealing plate 4 downward to close the installation opening 11, and at the same time drive the water cooler 2 to the installation point;

[0069] Step 3: Fixing the water cooler 2: Pushing the carrier plate 3 drives the movable plate 5 to move so that the support strip 92 is inserted into the support cavity 22 to achieve fixed installation of the water cooler 2;

[0070] Step 4: Connecting the water cooler 2 with the pipeline: The support plate frame 9 pushes the movable sleeve 26 to move, thereby connecting the water cooler 2 with the water inlet pipe 16 and the water outlet pipe 17.

[0071] When installing the water cooler 2, the contact base 21 is inserted into the limit carrier frame 44, and supported by the carrier base 72 to realize the positioning of the water cooler 2. Then the hydraulic rod 15 is started to drive the carrier plate 3 to move. As the carrier plate 3 moves, the sealing plate 4 is driven to move downward under the action of the pull-down channel 33, and finally covers the installation port 11. As the sealing plate 4 moves downward, it drives the water cooler 2 to move to the installation point and contact the heat dissipation part. As the carrier plate 3 moves, the sealing plate 4 is driven to move downward. The first hinge rod 54 will pull the supporting plate 6 downward relative to the sealing plate 4. As the supporting plate 6 moves downward, the second hinge rod 63 will push the supporting bar 7 to move away from the limiting frame 44. As the supporting bar 7 moves, it will also drive the hollow slat 8 to move synchronously with it. As the hollow slat 8 moves, it will also be pulled downward relative to the sealing plate 4 under the action of the first hinge rod 54. The hollow slats 8 are driven to move along the bearing strips 7, so that the support plate frame 9 is driven to move under the drive of the hollow slats 8, so that the support strips 92 on the support plate frame 9 are inserted into the support cavity 22, which plays a supporting and fixing role for the water cooler 2. When the water cooler 2 moves down to the installation point, the bearing bottom plate 72 is separated from the water cooler 2, the sealing plate 4 covers the installation port 11, and the driving connecting column 42 is inserted into the holding channel 32. In this way, as the carrier plate 3 continues to move, the push-up slats 91 will be connected with the movable The movable plate 272 contacts each other, thereby pushing the movable plate 272 to move, driving the movable sleeve 26 to move, so that the first inserting tube 28 on the movable sleeve 26 is inserted into the water inlet pipe 16, and the second inserting tube 29 is inserted into the water outlet pipe 17, forming 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, it is only necessary to start the hydraulic rod 15 to drive the sealing plate 4 to move upward, so that the water cooler 2 can be unlocked and quickly removed for easy maintenance.
