The rotation shaft 231 is provided in a hollow structure, and is provided with a third communication hole 232 and a fourth communication hole 233. The third communication hole 232 communicates with the inside of the shaft hole 131 and the inside of the rotation shaft 231, and the fourth communication hole 233 communicates with the inside of the rotation shaft 231 and the inside of the first cavity 110 of the upper mounting ring 100.

Referring to fig. 1, 3, 4 and 10, the other end of the lower mounting ring 200 is movably clamped with the other end of the upper mounting ring 100 through a locking assembly 300. The latch assembly 300 includes a latch 310 disposed on the upper mounting ring 100, a latch seat 320 disposed on the lower mounting ring 200, and a latch positioning assembly 330, where the latch positioning assembly 330 is connected to the latch seat 320, and is configured to enable the latch 310 to be slidably connected in one direction with respect to the latch seat 320, and to lock the upper mounting ring 100 and the lower mounting ring 200.

The latch seat 320 is provided with a latch groove 321. A spring is provided in the locking groove 321. The lock 310 can extend into the lock groove 321 and abut against the spring. The latch positioning assembly 330 includes a plurality of inclined slots disposed at two sides of the latch 310 and equally spaced along the direction of the latch 310 extending into the latch slot 321, and latch positioning members 331 respectively connected to two sides of the latch seat 320 and abutting against the inclined slots to form an inclined plane.

The latch positioning assembly 330 further includes a latch limiting mechanism 332 for controlling the latch positioning member 331 to abut against or disengage from the inclined slot of the latch 310, so as to lock or slidably adjust the latch 310 relative to the latch seat 320. The latch stop mechanism 332 includes a stop plate, a latch stop cavity, a spring, and an operating lever.

One end of the operating rod is fixedly connected with the limiting plate, and the limiting plate is slidably connected in the lock catch limiting cavity. The spring is sleeved on the operating rod and is arranged in the lock catch limiting cavity. One end of the spring is abutted on the limiting plate, the other end of the spring is abutted on one side of the lock catch limiting cavity, and the limiting plate is fixedly connected with one end, far away from the inclined plane, of the lock catch positioning piece 331. Pulling the two operation levers away from each other can drive the latch positioning piece 331 to disengage from the inclined slot of the latch 310, so that the latch 310 can be slidably adjusted relative to the latch seat 320. The two operation levers are pulled to be close to each other, so that the latch positioning piece 331 can be driven to be abutted against the inclined clamping groove of the latch 310, and the latch 310 is locked relative to the latch seat 320. When the two operation rods are far away from each other, the spring is in a compressed state, and when the two operation rods are close to each other, the spring is in a stretched state.

Referring to fig. 3, 4, 6 and 7, the other end of the upper mounting ring 100 is fixedly connected with a communication mechanism 400, the communication mechanism 400 includes a communication block 410, a connection control tube 420 disposed inside the communication block 410, the connection control tube 420 is slidably connected inside the communication block 410, and a communication limiting mechanism 430 for limiting the connection control tube 420 is further included. The lower mounting ring 200 is provided with a communication groove 440 that cooperates with the communication mechanism 400.

One end of the connection control tube 420 is set to be closed. When water is injected, the water has pressure on the closed end of the connection control tube 420. The two connection control pipes 420 are separated from each other under the action of water pressure, so that the two connection control pipes 420 are embedded in the connection hole 450. When the first cavity 110 and the second cavity 210 are filled with water, the two connection control pipes 420 are still embedded in the connection holes 450 under the action of the water pressure. When the connection control tube 420 is inserted into the connection hole 450, the communication spring 431 is in a compressed state.

When there is no water in the first cavity 110 and the second cavity 210, the two connection control pipes 420 are not pressurized, and the communication spring 431 cannot be kept in a compressed state. The communication spring 431 provides power to the two connection control pipes 420 to return the two connection control pipes 420 to the initial position. At the initial position, the connection control tube 420 moves to the inside of the communication block 410 and to a position where it does not block the opening of the lower mounting ring 200 and the lower mounting ring 200.

In this embodiment, in order to achieve communication between the interior of the second cavity 210 and the interior of the first cavity 110, the following arrangement is also provided:

the communication block 410 is provided in a hollow structure, and a fifth communication hole is provided on the upper mounting ring 100. The fifth communication hole communicates with the inside of the first cavity 110 of the upper mounting ring 100 and the inside of the communication block 410. The connection control pipe 420 is provided with a sixth communication hole 421. The sixth communication hole 421 communicates with the inside of the communication block 410 and the inside of the connection control pipe 420. The connection hole 450 communicates with the inside of the connection control tube 420 and the inside of the second cavity 210 of the lower mounting ring 200.

Referring to fig. 1, an accommodating space for accommodating a motor to be tested is formed between the lower mounting ring 200 and the upper mounting ring 100. The lower mounting ring 200 and the upper mounting ring 100 form a ring shape after locking, the ring shape having an inner circle and an outer circle. The motor to be tested is arranged in the annular inner circle.

Referring to fig. 1, 2, 8 and 9, the water inlet and exhaust control device 500 is disposed at the water inlet 120.

The upper mounting ring 100 is further provided with a plurality of ventilation holes 140 communicated with the first cavity 110, and the water inlet and exhaust control device 500 comprises a gas exchange mechanism 510, a water blocking plug 520, a water inlet pipeline 530 communicated with the water inlet 120, and a gas exchange pipeline 540 communicated with the plurality of ventilation holes 140. The gas exchange mechanism 510 is used for exchanging the gas inside the second cavity 210 and the first cavity 110 with the external air, so that the water injection is smoother.

The gas exchange mechanism 510 includes a control ball 511 provided in the water intake pipe 530, a control ball return spring 512 abutting against the control ball 511, a ventilation damper 513 provided in the gas exchange pipe 540, and a damper return spring 514 abutting against the ventilation damper 513. And the control ball 511 is fixedly connected with the ventilation baffle 513 through a connecting rod 515, and a plurality of ventilation holes 517 are formed in the ventilation baffle 513.

A control groove for facilitating the up-and-down movement of the control ball 511 and a control ball limiting plate 516 are provided in the water inlet pipe 530. The control ball limiting plate 516 is fixedly connected in the control slot. The control ball return spring 512 is disposed within a control ball limiting plate 516. The size of the control ball 511 is matched with the size of the water inlet 120. The size of the control ball 511 is smaller than the size of the control slot. In the process of injecting water into the first cavity 110 and the second cavity 120, the control ball 511 is moved downward by the water pressure, so that a gap is formed between the control ball 511 and the control groove, and the water inlet 120 is communicated with the water inlet pipe 530, so that cold water can be injected into the upper mounting ring 100 through the water inlet pipe 530. After stopping the water injection, the control ball return spring 512 provides upward power to the control ball 511, so that the control ball 511 can block the water inlet 120.

A ventilation groove for facilitating the upward and downward movement of the ventilation baffle 513 is provided in the gas exchange duct 520. The baffle return spring 514 is disposed within the ventilation slot. The ventilation flap 513 is matched to the shape of the ventilation slot. When the control ball 511 moves downward, the ventilation baffle 513 is driven to move downward, so that the ventilation holes 140 are communicated with the gas exchange pipeline and the outside, and ventilation can be performed.

Since the temperature of the water in the first cavity 110 and the second cavity 210 is higher than the temperature of the water just injected, a pressure difference is formed between the first cavity 110 and the second cavity 210, thereby causing water injection obstruction and slowing down the water injection speed. Therefore, the air pressure inside the first cavity 110 and the air pressure inside the second cavity 210 are exchanged with air through the plurality of ventilation holes 140, so that the air pressure inside the first cavity 110 and the air pressure inside the second cavity 210 can be reduced, and the water injection can be made smoother.

Referring to fig. 1, 8 and 9, the water blocking plug 520 is disposed inside the first cavity 110, connected to the baffle return spring 514, and can drive the ventilation baffle 513 to move up and down through the baffle return spring 514.

The water stopper 520 employs a float stopper. The float plug is fixedly connected with the baffle return spring 514 through a spring. When the float plug is moved upwards by the buoyancy of the water in the first cavity 110 and the second cavity 210, the water blocking plug 520 drives the ventilation baffle 513 and the control ball 511 to move upwards, so that the ventilation baffle 513 seals the ventilation hole 140, and water can be prevented from overflowing to cause water resource waste. At the same time, the control ball 511 is made to block the water inlet 120 so that water cannot be continuously injected into the first cavity 110 and the second cavity 210.

Referring to fig. 1, 11 to 14, a temperature-controlled water drain device 600 is disposed at the water outlet 220 for monitoring the temperature of water in the second cavity 210 and the first cavity 110, thereby monitoring the temperature of the motor to be measured and controlling water drain. The temperature controlled drain 600 includes a drain mechanism 610, a temperature monitoring mechanism 620, a water amount monitoring device 630, and a water amount limiting device.

Referring to fig. 1, 11 and 14, the temperature monitoring mechanism 620 includes a piston assembly, a piston return spring assembly. The piston assembly includes a piston chamber 621 disposed in the housing, a piston 622 slidably coupled within the piston chamber 621, and a piston rod 623. The piston 622 is fixedly connected to one end of the piston rod 623. The piston return spring assembly includes a piston return chamber 624, a piston return spring 625 slidably coupled within the piston return chamber 624, and a spring rod 626. One end of the spring rod 626 is fixedly connected with the piston return spring 625.

Referring to fig. 1 and 11 to 14, the drainage mechanism 610 includes a connection plate 611, a drainage port is provided on the connection plate 611, and the connection plate 611 has an initial position and a drainage position. When the connection plate 611 is at the initial position, the water outlets 220 on the lower mounting ring 200 are staggered with the water outlets on the connection plate 611, and the connection plate 611 seals the water outlets 220. When the connection plate 611 is in the drainage position, the water outlet 220 on the lower mounting ring 200 communicates with the water outlet on the connection plate 611 and the outside.

The other end of the piston rod 623 is fixedly connected with the connecting plate 611. The other end of the spring rod 626 is fixedly connected with the connecting plate 611.

The drain mechanism 610 further includes a housing, a drain passage 612, and a drain turbine 613 rotatably mounted within the drain passage 612. The connection plate 611 is slidably connected to the drainage channel 612, and divides the drainage channel 612 into two sections, so that the drainage mechanism 610 is divided into two cavities, an upper cavity and a lower cavity. A drain turbine 613 is disposed within the drain passage 612 within the lower cavity. When the water is discharged, the water can generate vortex, so that the circulation of air is accelerated, and the water can be rapidly discharged. The drain passage 612 communicates with the water outlet 220 on the lower mounting ring 200.

Referring to fig. 1 and fig. 11 to fig. 14, when the temperature monitoring mechanism 620 monitors that the temperature of the water in the second cavity 210 and the first cavity 110 is higher than the set value, the temperature monitoring mechanism 620 drives the connection plate 611 to move to the drainage position, so as to drain water. The temperature monitoring mechanism 620 is disposed within the housing of the drain mechanism 610.

In this embodiment, in order to realize that the temperature monitoring mechanism 620 monitors the temperature of the water in the second cavity 210 and the first cavity 110 and can drive the connection plate 611 to move to the drainage position, the following settings are made:

The drain passage 612 is provided with a seventh communication hole, which communicates with the inside of the drain passage 612 and the inside of the upper cavity of the drain mechanism 610. The piston assembly is disposed in the upper cavity of the drain mechanism 610 and the piston return spring assembly is disposed in the lower cavity of the drain mechanism 610. Water enters into the upper cavity of the drain mechanism 610 through the seventh communication hole. When the temperature of the water in the upper cavity is lower than the set value, the pressure in the piston chamber 621 is small, and the piston 622 cannot be moved. The connection plate 611 is in the initial position, and the connection plate 611 seals the water outlet 220, so that water cannot be discharged.

When the temperature of the water in the upper cavity is higher than the set value, the pressure in the piston cavity 621 is higher than the pressure in the piston cavity 621 in the initial state, so that the piston 622 can be driven to move, and the piston rod 623 and the connecting plate 611 are driven to move simultaneously. The water outlet on the connection plate 611 is communicated with the water outlet of the water discharge channel 612, so that rapid water discharge is performed. When the connection plate 611 is in the drainage position, the piston return spring disposed in the lower cavity is in a compressed state.

When the temperature of the water in the upper cavity is lower than the set value, the pressure in the piston cavity 621 is lower than the pressure of the piston cavity 621 in the initial state, the piston return spring 625 cannot be kept in the compressed state, the piston return spring 625 provides power for the connection plate 611, the connection plate 611 returns to the initial position, and the connection plate 611 seals the water outlet 220, so that water discharge is stopped.

Referring to fig. 1, 13 and 14, the water volume monitoring device 630 is used for monitoring the water volume in the second cavity 210 and the first cavity 110.

The water amount monitoring device 630 comprises a control float 631 and a connecting frame 632, wherein the control float 631 is fixedly connected to one end of the connecting frame 632. The other end of the connecting frame 632 is connected with the connecting plate 611 of the drainage mechanism 610 in a one-way sliding way through a water quantity limiting device. The water volume limiting device comprises a plurality of inclined clamping grooves which are arranged on the connecting plate 611 and are arranged at equal intervals along the length direction of the connecting plate 611, and limiting blocks which are connected on the connecting frame 632, are abutted with the inclined clamping grooves and form inclined plane matching.

When the water in the second cavity 210 and the water in the first cavity 110 are sufficient, the control float 631 receives buoyancy force to provide an upward force for the connection frame 632, so as to drive the limiting block of the connection frame 632 to abut against the inclined clamping groove of the connection plate 611. So that the connection plate 611 is locked with respect to the connection frame 632, thereby being able to restrict the movement of the connection plate 611 so that the connection plate 611 is continued to be in the drainage position.

When the water amount in the second cavity 210 and the first cavity 110 is insufficient to provide the upward buoyancy for the control float 631, the connection frame 632 will move downward under the action of gravity, so as to drive the limiting block of the connection frame 632 to disengage from the inclined clamping groove of the connection plate 611. So that the connection plate 611 is slidably adjustable with respect to the connection frame 632, thereby releasing the connection plate 611 so that the connection plate 611 can return to the original position.

Referring to fig. 12, the temperature-controlled drain device 600 further includes a connection plate stopper 640 for defining the position of the connection plate 611. The connection plate limiting device 640 is installed in the lower cavity of the drainage mechanism 610, and comprises an adjusting bolt 641, a spring installed at the end part of the adjusting bolt 641, and a limiting ball 642 installed at one end of the spring. The limit ball 642 can abut the connection plate 611 to define the position of the connection plate 611.

The motor temperature detection control device 10 further comprises a temperature detection device and a temperature display for detecting the temperature of the water in the second cavity 210 and the first cavity 110, and the temperature detection device is electrically connected with the temperature display. The temperature detecting means may be a temperature sensor, a temperature probe, or the like, as long as the function of detecting the temperature of the water inside the second cavity 210 and the first cavity 110 can be achieved.

The motor temperature detection control device 10 according to the present embodiment relates to a motor temperature detection control method when used for detecting a motor temperature. The method comprises the following steps:

the motor to be tested is placed in the receiving space formed between the lower mounting ring 200 and the upper mounting ring 100, and the lower mounting ring 100 is locked with the upper mounting ring 200.

Wherein, the lock catch 310 arranged on the upper mounting ring 100 is extended into the lock catch groove 321. Since the latch 310 is unidirectionally slidably coupled to the latch base 320 through the latch positioning assembly 330. When the lock catch 310 is at the installation position, the two operation levers are pulled to make the two operation levers approach each other, so that the lock catch positioning piece 331 can be driven to abut against the inclined clamping groove of the lock catch, and the lock catch 310 is locked relative to the lock catch seat 320, so as to lock the lower mounting ring 200 with the lower mounting ring 200.

Cold water is injected through the water inlet 120 into the first cavity 110 of the upper mounting ring 100 and into the second cavity 210 of the lower mounting ring 200.

The water inlet and exhaust control device 500 operates to exchange air inside the second cavity 210 and inside the first cavity 110 with outside air.

Wherein, when the cold water is injected, the control ball 511 is moved downward by the water pressure, so that a gap is formed between the control ball 511 and the control groove, so that the water inlet 120 communicates with the water inlet pipe 530, and thus the cold water can be injected into the inside of the upper mounting ring 100 through the water inlet pipe 530. When the control ball 511 moves downward, the ventilation baffle 513 is driven to move downward, so that the ventilation holes 140 are communicated with the gas exchange pipeline and the outside, and ventilation can be performed. The air pressure in the first cavity 110 and the second cavity 210 can be reduced, and water can be injected more smoothly.

The water has pressure on the closed end of the connection control tube 420. The two connection control pipes 420 are separated from each other by the water pressure such that the two connection control pipes 420 are embedded in the connection hole 450 of the lower mounting ring 200, so that the inside of the first cavity 110 of the upper mounting ring 100 is communicated with the inside of the second cavity 210 of the lower mounting ring 200. And the cold water reaches the second cavity 210 of the lower mounting ring 200 from the inside of the first cavity 110 of the upper mounting ring 100 through the first communication hole, the second communication hole, the third communication hole 232, and the fourth communication hole 233, so that the cold water is distributed inside the first cavity 110 and the second cavity 210.

When the float plug is moved upwards by the buoyancy of the water in the first cavity 110 and the second cavity 210, the water blocking plug 520 drives the ventilation baffle 513 and the control ball 511 to move upwards, so that the ventilation baffle 513 seals the ventilation hole 140, and water can be prevented from overflowing to cause water resource waste. At the same time, the control ball 511 is made to block the water inlet 120 so that water cannot be continuously injected into the first cavity 110 and the second cavity 210.

When the motor to be tested is in operation, heat is emitted, and cold water in the first cavity 110 and the second cavity 210 absorbs the heat absorbed by the motor to be tested. Causing the temperature of the water inside the first cavity 110 and the second cavity 210 to gradually rise.

The temperature-controlled drain 600 monitors the temperature of the water inside the second cavity 210 and the first cavity 110. When the temperature of the water inside the second cavity 210 and the first cavity 110 is higher than the set value, the temperature control drainage device 600 operates to drain the water inside the second cavity 210 and the first cavity 110. The hot water is taken away through drainage to realize cooling, thereby ensuring that the temperature of the tested motor is always kept within a certain range.

When the temperature monitoring mechanism 620 monitors that the temperature of the water in the second cavity 210 and the water in the first cavity 110 are higher than the set value, the pressure in the piston cavity 621 is higher than the pressure in the piston cavity 621 in the initial state due to the temperature rise, so that the piston 622 can be driven to move, and the piston rod 623 and the connecting plate 611 are driven to move simultaneously. The water outlet on the connection plate 611 is communicated with the water outlet of the water discharge channel 612, so that rapid water discharge is performed.

Meanwhile, the water amount monitoring device 630 is used for monitoring the water amount inside the second cavity 210 and the first cavity 110. When the water in the second cavity 210 and the water in the first cavity 110 are sufficient, the control float 631 receives buoyancy force to provide an upward force for the connection frame 632, so as to drive the limiting block of the connection frame 632 to abut against the inclined clamping groove of the connection plate 611. So that the connection plate 611 is locked with respect to the connection frame 632, thereby restricting the movement of the connection plate 611, preventing the connection plate 611 from returning to the original position, and thus allowing the drainage to be continued.

Since the drain turbine 613 is provided in the drain passage 612, the drain speed is much greater than the water injection speed. When the water amount in the second cavity 210 and the first cavity 110 is insufficient to provide the upward buoyancy for the control float 631, the connection frame 632 will move downward under the action of gravity, so as to drive the limiting block of the connection frame 632 to disengage from the inclined clamping groove of the connection plate 611. So that the connection plate 611 is slidably adjustable with respect to the connection frame 632 to return the connection plate 611 to the original position. Meanwhile, when the temperature monitoring mechanism 620 monitors that the temperature of the water in the second cavity 210 and the water in the first cavity 110 are lower than the set value, the pressure in the piston cavity 621 is lower than the pressure in the piston cavity 621 in the initial state due to the temperature decrease, the piston return spring 625 cannot be kept in the compressed state, the piston return spring 625 provides power for the connection plate 611, the connection plate 611 returns to the initial position, and the connection plate 611 seals the water outlet 220, so that drainage is stopped.
