Referring to fig. 1, 3, 4 and 5, one end of the lower mounting ring 200 is hinged to one end of the upper mounting ring 100.

In this embodiment, in order to realize that one end of the lower mounting ring 200 is hinged to one end of the upper mounting ring 100, the following settings are made:

A groove part 230 is formed at one end of the upper mounting ring 100, and a rotation shaft 231 engaged with the shaft hole 131 is formed on both inner walls of the groove part 230, respectively. The protrusion 130 at one end of the lower mounting ring 200 is embedded in the groove 230 at one end of the upper mounting ring 100 and is hinged to the shaft hole 131 through the rotation shaft 231.

In the present embodiment, in order to communicate the inside of the second cavity 210 with the inside of the first cavity 110, the following configuration is made:

the protrusion 130 is a hollow structure, and a first communication hole is formed on the lower mounting ring 200, and a second communication hole is formed on the protrusion 130. The first communication hole communicates with the inside of the second cavity 210 of the lower mounting ring 200 and the inside of the protrusion 130. The second communication hole communicates with the inside of the projection 130 and the inside of the shaft hole 131. The rotation shaft 231 is hollow and 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 rotary shaft 231, and the fourth communication hole 233 communicates with the inside of the rotary 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 engaged with the other end of the upper mounting ring 100 by a locking assembly 300. The locking assembly 300 includes a locking device 310 disposed on the upper mounting ring 100, a locking device holder 320 disposed on the lower mounting ring 200, and a locking device positioning assembly 330, wherein the locking device positioning assembly 330 is connected to the locking device holder 320, and is used to enable the locking device 310 to be slidably connected to the locking device holder 320 in a single direction and to lock the upper mounting ring 100 and the lower mounting ring 200.

The latch holder 320 is provided with a latch groove 321. A spring is provided in the locking groove 321. The latch 310 can extend into the latch slot 321 and abut the spring. The locking positioning assembly 330 includes a plurality of oblique slots disposed on both sides of the lock 310 and disposed at equal intervals along the direction in which the lock 310 extends into the lock slot 321, and a locking positioning member 331 connected to both sides of the lock holder 320 and abutting against the oblique slots to form an oblique surface fit.

The locking positioning assembly 330 further includes a locking limiting mechanism 332 for controlling the locking positioning member 331 to abut against or separate from the inclined slot of the locking device 310, so that the locking device 310 is locked or slidably adjusted relative to the locking seat 320. The lock catch limiting mechanism 332 comprises a limiting plate, a lock catch limiting cavity, a spring and an operating rod.

One end of the operating rod is fixedly connected with the limiting plate, and the limiting plate is connected in the lock catch limiting cavity in a sliding mode. The spring sleeve is arranged on the operating rod and arranged in the lock catch limiting cavity. One end of the spring abuts against the limiting plate, the other end of the spring abuts against 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, of the lock catch positioning piece in a matched mode. The two operating rods are pulled to move away from each other, so as to drive the locking positioning element 331 to disengage from the inclined clamping groove of the lock catch 310, and thus the lock catch 310 can be adjusted in a sliding manner relative to the lock catch holder 320. The two operating rods are pulled to approach each other, so as to drive the locking positioning element 331 to abut against the inclined clamping groove of the lock catch 310, thereby locking the lock catch 310 relative to the lock catch holder 320. When the two operating levers are far away from each other, the spring is in a compressed state, and when the two operating levers 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 the connection control tube further includes a communication limiting mechanism 430 for limiting the connection control tube 420. The lower mounting ring 200 is provided with a communication groove 440 to be engaged with the communication means 400. Both sides of the communication groove 440 are provided with connection holes 450 for coupling with the connection control pipe 420.

The communication means 400 can be inserted into the communication groove 440 in a state where the lower mounting ring 200 is locked with the upper mounting ring 100. The connection control tubes 420 are two and are respectively disposed at two ends of the connection block 410. The communication limiting mechanism 430 comprises a communication limiting cavity arranged in the upper communication block 410, a communication spring 431 arranged in the communication limiting cavity, and a communication plate 432. The communicating plate 432 is fixedly connected to the connecting control pipe 420, the communicating spring 431 is sleeved on the connecting control pipe 420, one end of the communicating spring 431 is fixedly connected with the communicating plate 432, and the other end of the communicating spring 431 is abutted against one side of the communicating limiting cavity. The communication plate 432 is abutted against the other side of the communication limiting cavity, so that the connection control tube 420 is slidably connected in the communication block 410 within a certain range.

The connection control tube 420 is provided with one end closed. When water is injected, the water has pressure on the closed end of the connection control pipe 420. The two connection control pipes 420 are separated from each other by the hydraulic pressure, so that the two connection control pipes 420 are inserted into the connection holes 450. When the first cavity 110 and the second cavity 210 are filled with water, the two connection control pipes 420 are still inserted into the connection holes 450 under the action of water pressure. When the connection control tube 420 is fitted 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 connection control pipes 420 are not pressurized, and the communication spring 431 cannot be continuously compressed. The communication spring 431 powers the two connection control tubes 420 to return the two connection control tubes 420 to the initial position. In the initial position, the connection control pipe 420 moves to the inside of the communication block 410, and moves to a position where it does not block the lower mount ring 200 from being opened with the lower mount ring 200.

In the present embodiment, in order to achieve communication between the inside of the second cavity 210 and the inside of the first cavity 110, the following configuration is also provided:

the communication block 410 is provided in a hollow structure, and the upper mounting ring 100 is provided with a fifth communication hole. 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 pipe 420 and the inside of the second cavity 210 of the lower mounting ring 200.

Referring to fig. 1, an accommodating space for accommodating the motor to be measured 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 being locked, and the ring shape has an inner circle and an outer circle. The tested motor 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 ventilating 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 pipe 530 communicated with the water inlet 120, and a gas exchange pipe 540 communicated with the plurality of ventilating holes 140. The gas exchange mechanism 510 is used for exchanging the gas inside the second cavity 210 and the gas inside the first cavity 110 with the outside air, so that the water injection is smoother.

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

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 the control ball limiting plate 516. The size of the control ball 511 matches the size of the water inlet 120. The size of the control ball 511 is smaller than that of the control groove. In the process of filling water into the first and

second cavities

110 and 120, the control ball 511 is moved downward by 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, thereby allowing cold water to be injected into the upper mounting ring 100 through the water inlet pipe 530. After the water injection is stopped, control ball return spring 512 provides upward power to control ball 511 to allow control ball 511 to block off water inlet 120.

A ventilation groove for facilitating the up-and-down movement of the ventilation damper 513 is provided in the gas exchange duct 520. The flapper return spring 514 is disposed within the breather tank. The ventilation baffle 513 is matched with the ventilation slot in shape. 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 pipe and the outside, thereby performing ventilation.

Since the temperature of the water inside the first cavity 110 and the water inside the second cavity 210 are higher than the temperature of the water just injected, a pressure difference is formed inside the first cavity 110 and the second cavity 210, which may cause a water injection obstacle and slow down the water injection speed. Therefore, the plurality of ventilation holes 140 exchange the air pressure inside the first cavity 110 and the second cavity 210 with the air, 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 performed more smoothly.

Referring to fig. 1, 8 and 9, the water blocking plug 520 is disposed in 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 shutoff plug 520 adopts a float plug. 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 water in 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 blocks the ventilation hole 140, and the water overflow can be prevented, thereby causing water 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 control drainage device 600 is disposed at the water outlet 220, and is used for monitoring the temperature of the water inside the second cavity 210 and the first cavity 110, so as to monitor the temperature of the motor to be tested, and control drainage. The temperature control drainage device 600 comprises a drainage mechanism 610, a temperature monitoring mechanism 620, a water quantity monitoring device 630 and a water quantity 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 connected in 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 bar 626 is fixedly connected to the piston return spring 625.

Referring to fig. 1, 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 connecting plate 611 is in the initial position, the water outlet 220 on the lower mounting ring 200 is staggered with the water outlet on the connecting plate 611, and the connecting plate 611 blocks the water outlet 220. When the connection plate 611 is in the drainage position, the water outlet 220 of the lower mounting ring 200 is communicated with the drainage port of 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 bar 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 inside the drain passage 612. The connecting plate 611 is slidably connected in the drainage channel 612 and divides the drainage channel 612 into two sections, thereby dividing the drainage mechanism 610 into two cavities, an upper cavity and a lower cavity. A drain turbine 613 is disposed in the drain passage 612 in the lower cavity. The water can generate vortex during water drainage, so that the circulation of air is accelerated, and water can be quickly drained. The drain passage 612 communicates with the water outlet 220 on the lower mounting ring 200.

Referring to fig. 1, 11 to 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 a set value, the temperature monitoring mechanism 620 drives the connecting plate 611 to move to the drainage position, so as to drain the 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 connecting plate 611 to move to the drainage position, the following settings are made:

the drain passage 612 is provided with a seventh communication hole, and the seventh communication hole 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 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 cavity 621 is lower, and the piston 622 cannot move. The connection plate 611 is at an initial position, and the connection plate 611 blocks the water outlet 220, so that water cannot be drained.

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, and the piston 622 can be driven to move, so that the piston rod 623 and the connecting plate 611 are driven to move simultaneously. The water outlet of the connecting plate 611 is communicated with the water outlet of the water drainage channel 612, so that the water can be drained quickly. When the connection plate 611 is in the drain 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 a set value, the pressure in the piston cavity 621 is lower than the pressure in the piston cavity 621 in the initial state, the piston return spring 625 cannot be continuously in the compressed state, the piston return spring 625 provides power for the connecting plate 611, and the connecting plate 611 returns to the initial position, so that the connecting plate 611 seals the water outlet 220, and the water discharge is stopped.

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

The water amount monitoring means 630 includes a control float 631, and a connection bracket 632, and the control float 631 is fixedly connected to one end of the connection bracket 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 quantity 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 a limiting block which is connected to the connecting frame 632, is abutted against the inclined clamping grooves and forms inclined surface matching.

When the water in the second cavity 210 and the first cavity 110 is sufficient, the control float 631 receives buoyancy to provide upward force for the connecting frame 632, and can drive the limiting block of the connecting frame 632 to abut against the inclined clamping groove of the connecting plate 611. So that the connection plate 611 is locked with respect to the connection frame 632 and thus the movement of the connection plate 611 can be restricted to allow the connection plate 611 to continue to be in the drainage position.

When the amount of water in the second cavity 210 and the first cavity 110 is not enough to provide the upward buoyancy for the control float 631, the connecting frame 632 moves downward under the action of gravity, and the limiting block of the connecting frame 632 can be driven to be separated from the inclined groove of the connecting plate 611. So that the connection plate 611 is slidably adjusted with respect to the connection frame 632 to release the connection plate 611, so that the connection plate 611 can return to the original position.

Referring to fig. 12, the temperature-controlled water discharge apparatus 600 further includes a connection plate stopper 640 for limiting the position of the connection plate 611. The connecting plate stopper 640 is installed in the lower cavity of the drainage mechanism 610, and includes an adjusting bolt 641, a spring installed at an end of the adjusting bolt 641, and a stopper ball 642 installed at one end of the spring. The limit ball 642 can abut against 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, wherein the temperature detection device is used for detecting the temperature of water inside the second cavity 210 and the temperature of water inside 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 water inside 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 accommodating space formed between the lower mounting ring 200 and the upper mounting ring 100, and the lower mounting ring 100 and the upper mounting ring 200 are locked.

Wherein, the lock catch 310 disposed on the upper mounting ring 100 is inserted into the lock catch groove 321. Since the lock catch 310 is slidably connected to the lock catch seat 320 in one direction by the lock catch positioning component 330. When the lock catch 310 is located at the mounting position, the two operating rods are moved close to each other by pulling the operating rods, so as to drive the lock catch positioning element 331 to abut against the inclined clamping groove of the lock catch, and thus the lock catch 310 is locked with respect to the lock catch holder 320, so as to lock the lower mounting ring 200 and the lower mounting ring 200.

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

The water inlet and air outlet control means 500 operates to exchange air between the inside of the second cavity 210 and the inside of the first cavity 110 and the outside air.

When cold water is injected, the control ball 511 is moved downward by 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. 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 pipe and the outside, thereby performing ventilation. The air pressure inside the first cavity 110 and the air pressure inside the second cavity 210 can be reduced, so that water injection can be performed more smoothly.

The water has pressure on the closed end of the connection control pipe 420. The two connection control pipes 420 are separated from each other by the hydraulic pressure, so that the two connection control pipes 420 are inserted into the connection holes 450 of the lower mounting ring 200, and 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, second, third and fourth communication holes 232 and 233, so that the cold water is filled in the inside of the first cavity 110 and the inside of the second cavity 210.

When the float plug is moved upwards by the buoyancy of the water in the first cavity 110 and the water in 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 blocks the ventilation hole 140, and the water overflow can be prevented, thereby causing water 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 operates, heat is emitted, and the cold water in the first cavity 110 and the cold water in the second cavity 210 absorb the heat absorbed by the motor to be tested. The temperature of the water inside the first cavity 110 and the second cavity 210 is gradually increased.

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

When the temperature monitoring mechanism 620 monitors that the temperatures of the water in the second cavity 210 and the water in the first cavity 110 are higher than a set value, the temperature rises, so that the pressure in the piston cavity 621 is higher than the pressure in the piston cavity 621 in the initial state, and the piston 622 can be driven to move, thereby driving the piston rod 623 and the connecting plate 611 to move simultaneously. The water outlet of the connecting plate 611 is communicated with the water outlet of the water drainage channel 612, so that the water can be drained quickly.

Meanwhile, the water amount monitoring means 630 is used to monitor the amount of water inside the second cavity 210 and inside the first cavity 110. When the water in the second cavity 210 and the first cavity 110 is sufficient, the control float 631 receives buoyancy to provide upward force for the connecting frame 632, and can drive the limiting block of the connecting frame 632 to abut against the inclined clamping groove of the connecting plate 611. The connection plate 611 is locked with respect to the connection frame 632 so that the movement of the connection plate 611 can be restricted, the connection plate 611 cannot return to the initial position, and the water discharge can be continued.

Since the drain passage 612 is provided with the drain turbine 613, the speed of draining is much higher than the speed of injecting water. When the amount of water in the second cavity 210 and the first cavity 110 is not enough to provide the upward buoyancy for the control float 631, the connecting frame 632 moves downward under the action of gravity, and the limiting block of the connecting frame 632 can be driven to be separated from the inclined groove of the connecting plate 611. So that the connection plate 611 is slidably adjusted with respect to the connection frame 632 to return the connection plate 611 to the initial 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 is lower than a 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 reduction, so that the piston return spring 625 cannot be continuously in a compressed state, the piston return spring 625 provides power for the connecting plate 611, the connecting plate 611 returns to the initial position, the connecting plate 611 seals the water outlet 220, and the water drainage is stopped.
