Description

Technical Field

[0001] This utility model relates to the field of motor water pressure testing technology, specifically a motor water pressure testing device. Background Technology

[0002] As a power source, motors are often used in places where there are explosive gas or dust mixtures. As a major component of the motor, the quality of its explosion-proof performance directly affects the safety of the equipment. The motor housing is generally made of castings or welded steel plates, forming an independent explosion-proof cavity. After a motor housing is manufactured, it must be tested to determine whether its explosion-proof performance meets the design and standard requirements. Explosion-proof motor manufacturers generally use a hydraulic press for overpressure testing.

[0003] Chinese patent (publication number: CN 207908110 U) discloses an explosion-proof motor water pressure testing device, which can reduce the wear caused by the contact between the motor housing and the top cover plate and facilitate the replacement of the rubber gasket. However, after the water pressure test of the motor housing is completed in the above document, the water source will stick to the outside of the motor housing during the water pressure test. As a result, when the tested workpiece is taken out from the test end, the test water will drip onto the ground or table, causing the ground to be wet and wasting the test water.

[0024] Please see Figures 1 to 3 In this embodiment, the water removal assembly includes a horizontal plate 72 disposed at the top of the water storage tank 6. A dual-axis motor 75 is fixed to the bottom wall of the inner cavity of the horizontal plate 72. A rotating rod 74 is fixed to the output end of the dual-axis motor 75. A flip plate 73 is fixed to the other end of the two rotating rods 74. A rotary motor 76 is fixed inside the left side of the flip plate 73. The water removal assembly also includes a clamping structure disposed to the left side of the rotary motor 76.

[0025] Two electric telescopic rods 71 ​​are fixed to the right side wall of the horizontal plate 72, and two fixing holes are provided on the right side wall of the vertical plate 7 for fixing the two electric telescopic rods 71 ​​inside, so that the two electric telescopic rods 71 ​​can be fixed to the top of the water tank 6 through the vertical plate 7.

[0026] Furthermore, the horizontal plate 72 is a hollow rectangle, and both the front and rear ends of the horizontal plate 72 are provided with round holes for the two rotating rods 74 to pass through, so as to facilitate the connection between the two rotating rods 74 and the flip plate 73.

[0027] Furthermore, the flip plate 73 is concave in shape, and a hidden groove is provided on the left side of the flip plate 73 for fixing the rotary motor 76 inside it. The right side wall of the rotary motor 76 is fixed to the right side wall of the inner cavity of the hidden groove so that the rotary motor 76 can be fixed inside the flip plate 73.

[0028] Please see Figures 2 to 3 The clamping structure in this embodiment includes a connecting plate 77 fixed to the output end of the rotary motor 76. Two clamping blocks 78 are slidably connected to the left side wall of the connecting plate 77. A moving block 79 is fixed to the right side wall of the two clamping blocks 78. The clamping structure also includes a pulling structure disposed on the opposite side of the two moving blocks 79.

[0029] Secondly, a sliding hole is provided on the left side wall of the connecting plate 77, and the clamping block 78 is slidably connected inside the sliding hole, so that the clamping block 78 can be connected to the moving block 79.

[0030] Please see Figure 3 In this embodiment, the pulling structure includes a pull rope 713 on the side opposite to the two moving blocks 79. The other end of each pull rope 713 is fixed with a rotating rod 712. A gear 714 is fixed on the outer surface of the rotating rod 712. The two moving blocks 79 are slidably connected to a support rod 710. Two springs 711 are sleeved on the outer surface of the support rod 710.

[0031] Meanwhile, a drive motor is fixed to the top of the front rotating rod 712, and a round hole is opened at the top of the connecting plate 77 for the front rotating rod 712 to pass through its interior so that the drive motor can drive the front rotating rod 712 to rotate inside the connecting plate 77.

[0032] In addition, each of the two moving blocks 79 has a round hole on one side opposite to the other, so that the moving blocks 79 can move on the outer surface of the support rod 710 through the round hole, which facilitates the moving blocks 79 to compress the spring 711. The opposite ends of the two support rods 710 are respectively fixed to the front and rear walls of the inner cavity of the connecting plate 77. Each of the opposite ends of the two support rods 710 is fixed with a support block. The top of the support block is fixed to the bottom of the inner cavity of the connecting plate 77, so that the support rods 710 can rotate stably inside the connecting plate 77.

[0033] It should be noted that the electronic components mentioned in this article are all commonly known in the prior art, and the control method of this embodiment is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also commonly known in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0034] The working principle of the above embodiments is as follows:

[0035] When in use, when the cover plate 4 is reset upwards, the motor housing gradually floats to the water surface of the test chamber 1. The two electric telescopic rods 71 ​​drive the flip plate 73 to move to the left through the horizontal plate 72. The flip plate 73 can then drive the two clamping blocks 78 to the top of the test chamber 1 through the connecting plate 77. This allows the output end of the drive motor to drive the front rotating rod 712 to rotate. The front rotating rod 712 also drives the front gear 714 to rotate. When the front gear 714 meshes with the rear gear 714, it can drive the other rotating rod 712 to rotate. This allows the two rotating rods 712 to wind up the two pull ropes 713. The two pull ropes 713 can then pull the two clamping blocks 78 to move relative to each other through the two moving blocks 79. As the two moving blocks 79 move, they can cooperate with the support block to compress the spring 711, thereby clamping and fixing the two clamping blocks 78 to the motor housing.

[0036] The two electric telescopic rods 71 ​​can be moved to the top of the water tank 6 via the flip plate 73, which in turn moves the motor housing to the top of the water tank 6. This allows the dual-axis motor 75 to drive the two rotating rods 74 to rotate, which in turn drives the flip plate 73 to flip downwards, allowing the motor housing to flip into the water tank 6. This allows the output end of the rotary motor 76 to drive the motor housing to rotate via the connecting plate 77, thus dislodging the water from the surface of the motor housing and effectively reducing the waste of test water.
