[0002] Oil-cooled motors dissipate heat through the coolant in the oil tank. Testing the cooling effect of the oil tank is the key to ensuring the normal operation of the motor in a high-temperature environment. By testing the flow of coolant in the oil tank, temperature distribution, and heat dissipation efficiency, it is possible to evaluate whether the cooling system can meet the heat dissipation requirements of the motor and prevent the motor from being damaged due to overheating.

[0003] The existing oil tank detection device has the following problems:

[0008] When in use, pull the sealing plate, and the sealing plate drives the sealing magnetic gear to be removed from the upper wall of the motor housing, and put the straight oil tank body, micro-curved oil tank body and curved oil tank body made of the same material into the interior of the test cavity respectively. The straight oil tank body, micro-curved oil tank body and curved oil tank body have one side of the oil tank that fits the inner wall of the motor housing and slides to the upper wall of the support for placement. There is a gap between the oil tank of the straight oil tank body, micro-curved oil tank body and curved oil tank body and the support for the coolant to flow through the oil tank and fall into the bottom of the test cavity. After the straight oil tank body, micro-curved oil tank body and curved oil tank body are placed in the test cavity, the U-shaped heat insulation box is hung on the motor housing respectively. The upper wall of the motor housing is formed by a U-shaped heat insulation box, and one end of the U-shaped heat insulation box away from the oil inlet pipe is placed in the space between the oil tank of the straight oil tank body, the slightly curved oil tank body and the curved oil tank body and the inner wall of the motor housing. The sealing plate is placed on the upper wall of the U-shaped heat insulation box, and the sealing magnetic teeth are inserted into the space between the U-shaped heat insulation boxes and fit with the upper wall of the motor housing. The sealing magnetic teeth are magnetically adsorbed on the upper wall of the motor housing to complete the sealing of the motor housing, and then coolant is injected into the motor housing. The oil delivery pump draws the coolant inside the motor housing through the pumping end, and the coolant is transported to the inside of the arc tube through the discharge end of the oil delivery pump through the telescopic tube. The cooling inside the arc tube The coolant enters the U-shaped heat insulation box through the oil inlet pipe, and the U-shaped heat insulation box transports the coolant to the oil tanks of the linear oil tank body, the slightly curved oil tank body and the curved oil tank body through an opening at one end. When the oil pump extracts the coolant with the same force, the coolant flows in the pipeline at the same speed. Due to the different oil tank settings of the linear oil tank body, the slightly curved oil tank body and the curved oil tank body, the coolant flow rate slows down or increases after entering the oil tank. The heating coil heats the metal rod. The increase in the temperature of the metal rod drives the temperature inside the insulation tube to rise. The insulation tube heats the linear oil tank body placed in the test cavity through the heating port. The linear oil tank body, micro-curved oil tank body and curved oil tank body are heated, and the coolant takes away part of the heat when flowing through the oil tanks arranged on the side walls of the linear oil tank body, micro-curved oil tank body and curved oil tank body, so as to simulate the heat dissipation of the temperature inside the motor. The coolant flowing through the oil tanks of the linear oil tank body, micro-curved oil tank body and curved oil tank body respectively flows into the temperature measuring box through the circulation pipe, and the temperature sensor detects the temperature of the coolant flowing out of different test cavities respectively. When the temperature of the coolant flowing through the oil tank of the micro-curved oil tank body is detected to be higher, it means that the oil tank arranged with the micro-curved oil tank body has a better heat dissipation effect on the inside of the motor.

[0009] Preferably, the resistance-type wear measuring mechanism includes an adsorption electromagnet, an oil return pipe and a filter screen. The adsorption electromagnet is arranged on the inner wall of the bottom of the motor housing, the oil return pipe passes through the detection table and is connected between the coolant cylinder and the temperature measuring box, and the filter screen is arranged on the inner wall of one end of the coolant cylinder close to the oil pump.

[0010] When in use, the coolant inside the temperature measuring box flows back to the motor housing through the oil return pipe, and then the sealing plate is pulled to drive the sealing magnetic gear to be removed from the upper wall of the motor housing, and the straight oil tank body and the curved oil tank body are taken out from the inside of the test chamber, and the micro-curved oil tank bodies of different materials are placed in the test chamber. The sealing plate drives the sealing magnetic gear to fit the upper wall of the motor housing, and the heat dissipation of the micro-curved oil tank bodies made of different materials to the heat inside the motor is tested, so as to facilitate the selection of the micro-curved oil tank body with the best heat dissipation inside the motor. The oil pump supplies oil to the micro-curved oil tank body through the U-shaped heat insulation box. Coolant is transported inside the groove. Since the oil groove arranged on the side wall of the micro-curved oil groove body is a curve, the bending radius and bending angle will increase the impact force and wear of the coolant on the groove wall of the oil groove. At this time, the adsorption electromagnet is energized to generate magnetism. The adsorption electromagnet uses the effect of the magnetic field to adsorb metal debris in the coolant. The metal debris that cannot be adsorbed by the adsorption electromagnet is blocked by the filter. By comparing the metal debris inside the corresponding motor housing, the micro-curved oil groove body that is less worn by the coolant circulation is selected, thereby completing the inspection of the oil groove of the oil-cooled motor.

[0011] Specifically, a controller is provided on the upper wall of the sealing plate.

[0012] Wherein, the controller is electrically connected to the oil delivery pump, the temperature sensor and the adsorption electromagnet respectively.

[0013] The beneficial effects achieved by adopting the above structure are as follows:

[0014] Compared with the prior art, this solution adopts a multi-group comparative flow method, through the arrangement of a straight and curved heat absorption mechanism and a resistance type wear measuring mechanism, under the coordinated use of a partition mechanism, a heat conduction mechanism, an oil delivery mechanism, a sealing mechanism and a temperature measuring mechanism, under the same coolant flow velocity and the same heating temperature of a straight oil tank body, a slightly curved oil tank body and a curved oil tank body, it is possible to detect the influence of the curvature of the oil tank on the heat absorbed by the coolant inside the test cavity, thereby obtaining the oil tank with the best heat absorption, which is convenient for efficient heat dissipation inside the motor, and at the same time in the arrangement of the adsorption electromagnet and the filter screen. Under the setting, the coolant circulation test can be carried out on oil tanks of different materials with the same curvature, so as to detect the oil tank material that is less worn by the coolant circulation, thereby ensuring the use efficiency of the oil tank inside the motor. The adsorption electromagnet is energized to generate magnetism, and the adsorption electromagnet uses the effect of the magnetic field to adsorb metal debris in the coolant. The metal debris that cannot be adsorbed by the adsorption electromagnet is blocked by the filter. By comparing the metal debris inside the corresponding motor housing, the slightly curved oil tank body that is less worn by the coolant circulation is selected, thereby completing the detection operation of the oil tank of the oil-cooled motor.

The detection end of the temperature sensor 24 is arranged through the inside of the temperature measuring box 23, and the circulation pipe 25 passes through the detection platform 1 and is connected between the test cavity 8 and the temperature measuring box 23.

[0035] The resistance-type wear measuring mechanism 26 includes an adsorption electromagnet 27, an oil return pipe 28 and a filter screen 29. The adsorption electromagnet 27 is arranged on the inner wall of the bottom of the motor housing 3. The oil return pipe 28 passes through the detection platform 1 and is connected between the coolant cylinder 2 and the temperature measuring box 23. The filter screen 29 is arranged on the inner wall of one end of the coolant cylinder 2 close to the oil pump 17.

[0036] A controller 30 is disposed on the upper wall of the sealing plate 20 .

[0037] The controller 30 is electrically connected to the oil delivery pump 17 , the temperature sensor 24 , and the adsorption electromagnet 27 , respectively.

[0038] When in use, the sealing plate 20 is manually pulled, and the sealing plate 20 drives the sealing magnetic teeth 21 to be removed from the upper wall of the motor housing 3, and the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 made of the same material are respectively placed in the interior of the test cavity 8, and the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 have one side of the oil tank that is in contact with the inner wall of the motor housing 3 and slides down to the upper wall of the support 6 for placement, and a gap is left between the oil tanks of the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 and the support 6, so that the coolant can flow through the oil tank and fall into the bottom of the test cavity 8;

[0039] After the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 are placed inside the test chamber 8, the U-shaped heat insulation box 14 is hung on the upper wall of the motor housing 3 respectively, and the end of the U-shaped heat insulation box 14 away from the oil inlet pipe 15 is placed into the space between the oil tanks of the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 and the inner wall of the motor housing 3, and the sealing plate 20 is placed on the upper wall of the U-shaped heat insulation box 14, and the sealing magnetic teeth 21 are inserted into the space between the U-shaped heat insulation boxes 14 and fit with the upper wall of the motor housing 3, and the sealing magnetic teeth 21 are magnetically adsorbed on the upper wall of the motor housing 3, thereby completing the sealing of the motor housing 3;

[0040] Then, the coolant is injected into the motor housing 3, and the controller 30 controls the oil pump 17 to start. The oil pump 17 extracts the coolant inside the motor housing 3 through the pumping end, and the coolant is transported to the arc tube 16 through the discharge end of the oil pump 17 through the telescopic tube 18. The coolant inside the arc tube 16 enters the U-shaped heat insulation box 14 through the oil inlet pipe 15. The U-shaped heat insulation box 14 transports the coolant to the oil tanks of the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33 through an opening at one end. Under the same extraction force of the coolant by the oil pump 17, the circulation speed of the coolant inside the pipeline is consistent. Due to the different oil tank settings of the straight oil tank body 31, the slightly curved oil tank body 32 and the curved oil tank body 33, the flow rate of the coolant slows down or increases after the coolant enters the oil tank.

[0041] The controller 30 controls the heating coil 11 to start, and the heating coil 11 heats the metal rod 10. The temperature increase of the metal rod 10 drives the temperature inside the heat preservation tube 12 to increase. The heat preservation tube 12 heats the straight oil tank body 31, the micro-bend oil tank body 32 and the curved oil tank body 33 placed inside the test cavity 8 through the heating port 34. The coolant takes away a part of the heat when flowing through the oil tanks set on the side walls of the straight oil tank body 31, the micro-bend oil tank body 32 and the curved oil tank body 33, which is used to simulate the heat dissipation of the temperature inside the motor. The coolant flowing through the oil tanks of the straight oil tank body 31, the micro-bend oil tank body 32 and the curved oil tank body 33 flows into the temperature measuring box 23 through the circulation pipe 25 respectively. The controller 30 controls the temperature sensor 24 to start, and the temperature sensor 24 detects the temperature of the coolant flowing out from different test cavities 8 respectively. When it is detected that the temperature of the coolant flowing through the oil tank of the micro-bend oil tank body 32 is higher, it means that the oil tank set by the micro-bend oil tank body 32 has a better heat dissipation effect on the inside of the motor.

[0042] The coolant inside the temperature measuring box 23 flows back to the motor housing 3 through the oil return pipe 28, and then the sealing plate 20 is pulled to drive the sealing magnetic gear 21 to be removed from the upper wall of the motor housing 3, and the straight oil tank body 31 and the curved oil tank body 33 are taken out from the inside of the test chamber 8, and the micro-curved oil tank body 32 of different materials is placed into the test chamber 8. The sealing plate 20 drives the sealing magnetic gear 21 to fit with the upper wall of the motor housing 3, and the heat dissipation of the micro-curved oil tank bodies 32 of different materials to the heat inside the motor is tested, so as to facilitate the selection of the micro-curved oil tank body 32 for the best heat dissipation inside the motor, and the oil pump 17 delivers coolant to the oil tank of the micro-curved oil tank body 32 through the U-shaped heat insulation box 14 Since the oil groove arranged on the side wall of the micro-curved oil groove body 32 is a curve, the bending radius and the bending angle will increase the impact force and wear of the coolant on the wall of the oil groove. At this time, the controller 30 controls the adsorption electromagnet 27 to start, and the adsorption electromagnet 27 is energized to generate magnetism. The adsorption electromagnet 27 uses the effect of the magnetic field to adsorb metal debris in the coolant. The metal debris that cannot be adsorbed by the adsorption electromagnet 27 is blocked by the filter 29. By comparing the metal debris inside the corresponding motor housing 3, the micro-curved oil groove body 32 that is less worn by the circulation of the coolant is selected, thereby completing the detection operation of the oil groove of the oil-cooled motor; the above operation can be repeated the next time it is used.
