Description

Technical Field

[0002] The pressure-maintaining leakage and temperature detection device for the new energy motor water channel quick plug is a comprehensive equipment specially used in the new energy motor water channel system to perform pressure monitoring, leakage detection and temperature measurement on the quick plug connection parts. The motor water channel is connected through a quick connector, and the air tightness test is performed on the entire machine to ensure the sealing reliability of the cooling system and electrical components in high-pressure and high-humidity environments. The quick plug is combined with a pressure test to ensure the sealing of the charging pile liquid cooling circuit and reduce the risk of equipment downtime caused by coolant leakage. The leak tester is connected to determine whether there are tiny leaks in the cooling water channel to prevent coolant leakage from causing motor overheating or short circuit. Temperature monitoring can warn of faults caused by condensation inside the equipment or sudden changes in ambient temperature. The above application scenarios cover the core needs of new energy motors and related equipment in terms of sealing, thermal management, and environmental adaptability through the combination of pressure-maintaining leakage detection technology and temperature monitoring.

[0003] However, the conventional device still has the following problems when used: In some testing scenarios where the performance of the motor water channel is extremely demanding, the existing quick-connect plug body only serves as a connection and cannot flexibly control the cooling water flow according to actual needs.

The outer wall of the end is movably connected to the joint of the outer wall on the back side of the temperature circulating water system 2. The outer wall of the other side of the electromagnetic three-way valve 9 is fixedly connected to the outlet pipe, and the outer wall of the other side of the electromagnetic three-way valve 9 is fixedly connected to the return pipe.

The outer wall of one end of the outlet pipe is fixedly connected to the quick plug body 11, and the quick plug body 11 is provided with a flow control mechanism. The quick plug body 11 is provided with a connecting mechanism. The upper part of the inner wall of the quick plug body 11 is fixedly connected to a pressure sensor 16, and the lower part of the inner wall of the quick plug body 11 is fixedly connected to a temperature sensor 17. The flow control mechanism includes a fixed sleeve 12, the outer wall of the fixed sleeve 12 is fixedly connected to the inner wall of the quick plug body 11, and the connecting mechanism includes a bag 131, and the outer wall of the bag 131 is fixedly connected to the inner wall of the quick plug body 11.

[0029] Turn on the infrared thermal imaging 6 and observe it through the test computer. In a low temperature environment, the sample surface should show a blue image. If a red area appears in the image, it indicates that there is a high-temperature cooling water leak at that location, which needs to be listed as a key inspection area. If there is no abnormal red in the image, it means that the leakage is normal at this time and the test can be officially started.

[0030] Example 2. On the basis of Example 1, the outer wall of one side of the motor sample 5 to be tested is connected to a connecting tube 51, and a groove 1 52 is provided on the outer wall of the connecting tube 51. The outer wall of the connecting tube 51 is movably plugged into the interior of the quick plug body 11. The inner wall of one end of the quick plug body 11 is fixedly connected to a sealing ring 111, and a groove 2 142 is provided on the inner wall of the quick plug body 11. A reset spring 143 is fixedly connected to the inner wall of the groove 2 142. The interior of the quick plug body 11 is movably connected to the mounting groove 14, and the outer wall on one side of the mounting groove 14 is fixedly connected to the outer wall of one end of the reset spring 143. The interior of the mounting groove 14 is movably contacted with a filter screen 141, and the outer wall on one side of the filter screen 141 is movably contacted with the outer wall of one end of the connecting tube 51.

[0031] As the connecting tube 51 is pushed into the quick plug body 11, the connecting tube 51 pushes the installation groove 14 to move into the quick plug body 11. When the connecting tube 51 can no longer be pushed, it proves that the installation of the connecting tube 51 is complete. This allows the operator to quickly and accurately determine whether the connecting tube 51 is properly installed, preventing problems such as loose connections and leakage caused by improper installation, thereby improving installation efficiency and accuracy. By installing the filter screen 141 inside the groove 14, the liquid is filtered when passing through the filter screen 141, thereby preventing impurities from flowing into the water channel of the motor and causing blockage of the water channel of the motor. The fluidity of the water channel of the motor is correspondingly increased, the risk of blockage of the water channel of the motor is reduced, and the service life of the motor is extended.

[0032] Example three, on the basis of Example two, flow holes are provided on the outer walls on both sides of the fixed sleeve 12, an adjusting tube 121 is slidably connected inside the fixed sleeve 12, a raised plate 123 is fixedly connected to the outer wall of the adjusting tube 121, a cavity 124 is provided inside the fixed sleeve 12, the inner wall of the cavity 124 is fitted and slidably connected to the outer wall of the raised plate 123, a fixing rod 122 is fixedly connected to the lower part of the inside of the fixed sleeve 12, a cavity 2 125 is provided inside the adjusting tube 121, the inner wall of the cavity 2 125 is fitted and slidably connected to the outer wall of the fixing rod 122, and a flow sensor 126 is fixedly connected to the outer wall of the bottom of the adjusting tube 121.

[0033] The opening or closing of the inlet and outlet ends of the flow tube 13 is controlled by rotating the regulating tube 121. This operation is simple and quick, avoiding the need for complex steps to achieve this effect. This correspondingly reduces the complexity of opening or closing the inlet and outlet ends of the flow tube 13, saving operation time and energy. When the regulating tube 121 moves upward, the liquid inside the quick plug body 11 can flow through the flow holes on the fixed sleeve 12. By setting up the flow sensor 126, the flow rate of the liquid inside the quick plug body 11 can be converted into an electrical signal and transmitted to the test computer. When the flow rate is lower than the set range, the operator pulls the adjustment tube 121 to adjust it. Through this real-time monitoring and adjustment mechanism, it can quickly respond to flow changes, ensuring that the liquid flow rate always remains within the set range, meeting strict test standards, and improving the accuracy and reliability of test results.

[0034] Embodiment 4. On the basis of embodiment 3, the outer wall of the sac 131 is in active contact with the inner wall of the groove 152, the outer wall of the sac 131 is fixedly connected to the circulation tube 13, the outer wall of the circulation tube 13 is fixedly connected to the interior of the quick plug body 11, the outer wall of one end of the circulation tube 13 is connected to the interior of the fixed sleeve 12, a T-shaped slot 132 is provided on the inner wall of the top of the cavity 124, a slider 134 is slidably connected to the interior of the T-shaped slot 132, a sealing block 133 is fixedly connected to the outer wall of the bottom of the slider 134, a magnetic block 135 is fixedly connected to the outer wall of one side of the sealing block 133, the outer wall of the sealing block 133 is in active contact with the outer wall of one end of the circulation tube 13, a placement groove is provided inside the regulating tube 121, a strip magnetic plate 136 is fixedly connected to the interior of the placement groove, the outer wall of one side of the strip magnetic plate 136 is attracted to the outer wall of one side of the magnetic block 135 by opposite poles.

[0035] A large amount of hydraulic oil enters the interior of the bladder 131, propping up the deflated bladder 131, so that the outer wall of the bladder 131 fits tightly with the interior of the groove 1 52. The tight fit increases the friction and contact area between the bladder 131 and the connecting tube 51, thereby enhancing the fixing effect of the bladder 131 on the connecting tube 51, making the connection more firm and reliable, and effectively preventing the connecting tube 51 from loosening or falling off during subsequent use. At the same time, the vibration generated during the motor test can be better absorbed and buffered by the tightly fitting bladder 131, reducing the impact of the vibration on the connection between the connecting tube 51 and the quick plug body 11, ensuring that the connection remains stable under various working conditions.

[0036] Embodiment 5. On the basis of embodiment 3, a through hole is provided on the outer wall of the raised plate 123, and the interior of the through hole is fixedly connected to the mounting shell 15, and the interior of the mounting shell 15 is movably connected to the movable plate 151, and the upper part of the inner wall of the mounting shell 15 is fixedly connected to the blocking rod three 153, and the outer wall of one end of the blocking rod three 153 is movably plugged into the interior of the movable plate 151, and the upper part of the inner wall of the mounting shell 15 is fixedly connected to the balancing spring one 154, and the outer wall of one end of the balancing spring one 154 is fixedly connected to the outer wall of one side of the movable plate 151, and the lower part of the inner wall of the mounting shell 15 is fixedly connected to the smoothing spring two 155, and the outer wall of one end of the smoothing spring two 155 is fixedly connected to the outer wall of the other side of the movable plate 151, and the lower part of the inner wall of the mounting shell 15 is fixedly connected to the blocking rod one 152, and the outer wall of one end of the blocking rod one 152 is movably plugged into the interior of the movable plate 151.

[0037] The hydraulic oil inside the cavity 124 is subjected to the extrusion force, pushing the movable plate 151 to move downward, so that the blocking rod 3 153 leaves the inside of the movable plate 151, and the hydraulic oil can move downward through the movable plate 151. When the movement of the regulating tube 121 is stopped, the movable plate 151 can be pushed to return to its original position under the action of the balance spring 154 and the smooth spring 2 155. When the hydraulic oil flows through the circular hole and the movable plate 151, the upward movement speed of the regulating tube 121 can be slowed down. This slow movement makes it easier for the operator to adjust the flow rate more finely, prevents excessive flow fluctuations due to too fast adjustment, and further improves the accuracy of flow control.

[0038] The working principle and use process of the present invention are as follows: when working, first, complete the appearance inspection of the motor sample 5 to be tested, and after confirming that there is no abnormality, place it stably in the rapid temperature change test box 4, and then connect the leaking air pipe and the temperature circulating water pipe 10 to the quick plug body 11 on the equipment respectively to form a complete circuit, turn on the test computer and related monitoring software, and then start the leakage meter 3, operate the electromagnetic three-way valve 9 to open the leaking air pipe, and close the temperature circulating water pipe 10 at the same time. At this time, carry out the waterway airtight connection test on the motor sample 5 to carefully check whether there is a leak point in the circuit and confirm whether the leakage value meets the standard requirements set by the customer. If the airtightness inspection is qualified, operate the quick plug body 11 again to turn on the temperature circulation. Circular water pipe 10, close the leaking air pipe, ensure that the loop is switched to the water flow state, then check whether the readings of the water outlet pressure gauge 7 and the return water pressure gauge 8 are zero, if not, perform the zeroing operation, then start the temperature circulating water system 2, and control the program through the test computer to output the preset temperature and water flow. At the same time, set a low temperature environment for the rapid temperature change test chamber 4. After the low temperature environment reaches a stable state, turn on the infrared thermal imaging 6 and observe it through the test computer. In the low temperature environment, the sample surface should show a blue image. If a red area appears in the image, it indicates that there is a high-temperature cooling water leak at that location, which needs to be listed as a key inspection area. If there is no abnormal red on the image, it means that the leakage is normal at this time and the test can be officially started.

[0039] After placing the motor sample 5 to be tested into the rapid temperature change test chamber 4, first, one end of the connecting tube 51 is inserted into the quick plug body 11. Due to the certain deformation ability of the sealing ring 111 provided in the quick plug body 11, after the connecting tube 51 is inserted into the quick plug body 11, the sealing ring 111 is tightly fitted with the outer wall of the connecting tube 51, thereby preventing liquid from leaking from the connection between the connecting tube 51 and the quick plug body 11. Accordingly, the sealing performance of the connection between the quick plug body 11 and the connecting tube 51 is improved, ensuring that the liquid circulates according to the preset path and flow rate during the test. The collected temperature, pressure, flow rate and other data accurately reflect the actual performance of the motor water channel under the rapid temperature change environment, providing a reliable basis for subsequent analysis and evaluation.

[0040] When the connecting tube 51 is pushed into the interior of the quick plug body 11, one end of the connecting tube 51 is inserted into the interior of the installation groove 14 and contacts the filter 141. When the connecting tube 51 is pushed into the interior of the quick plug body 11, the connecting tube 51 pushes the installation groove 14 to move into the interior of the quick plug body 11. When the connecting tube 51 can no longer be pushed, it proves that the installation of the connecting tube 51 is complete, allowing the operator to quickly and accurately determine whether the connecting tube 51 is installed in place, preventing problems such as loose connection and leakage caused by inadequate installation, and improving installation efficiency and accuracy. At this time, the bag 131 inside the quick plug body 11 enters the interior of the groove 152. It should be emphasized that the installation groove 14 is tightly attached to the inner wall of the quick plug body 11. The mounting groove 14 is tightly fitted and has a sealing property. When the connecting tube 51 pushes the mounting groove 14 to move into the quick plug body 11, this tightly fitting structure ensures the stability of the mounting groove 14, preventing it from shaking or shifting during installation, thereby ensuring the reliability of the entire connection structure. In addition, because the mounting groove 14 and the quick plug body 11 are tightly fitted and sealed, liquid is effectively prevented from flowing out of the contact surface between the two. The liquid is then filtered by the filter screen 141 provided inside the mounting groove 14, preventing impurities from flowing into the motor water channel and causing blockage of the motor water channel. This correspondingly increases the fluidity of the motor water channel, reduces the risk of blockage of the motor water channel, and extends the service life of the motor.

[0041] After the bag 131 is inserted into the interior of the groove 152 through the connecting tube 51, the bottom of the adjusting tube 121 is tightly fitted with the lower part of the interior of the fixing sleeve 12, and the adjusting tube 121 completely blocks the flow holes on both sides of the fixing sleeve 12. At this time, the operator rotates the adjusting tube 121 by hand. Due to the attraction between the opposite poles of the strip magnetic plate 136 and the magnetic block 135, the strip magnetic plate 136 can drive the magnetic block 135 to rotate while the adjusting tube 121 rotates. Then, through the fixed connection between the magnetic block 135 and the sealing block 133, the sealing block 133 moves accordingly while the magnetic block 135 rotates, and then through The rotation of the sealing block 133 drives the slider 134 to rotate within the T-slot 132, thereby causing the sealing block 133 to move away from one side of the circulation tube 13, so that the inlet and outlet ends of the circulation tube 13 come into contact with the interior of the cavity 124. The opening or closing of the inlet and outlet ends of the circulation tube 13 is controlled by rotating the adjustment tube 121. This operation is simple and quick, avoiding the need for complex steps to achieve this effect, and correspondingly reducing the complexity of opening or closing the inlet and outlet ends of the circulation tube 13, saving operation time and effort. When the adjustment tube 121 moves upward, the liquid inside the quick plug body 11 can flow through the flow hole on the fixed sleeve 12.

[0042] It should be noted that when the regulating tube 121 moves up and down, the sealing block 133 will also move up and down driven by the strip magnetic plate 136 .

[0043] It should be noted that the housing of the fixing sleeve 12 is transparent, so as to facilitate observation of the flow of the hydraulic oil inside.

[0044] After opening the circulation tube 13, the operator pulls the regulating tube 121 upwards, and then drives the raised plate 123 upwards through the regulating tube 121, squeezing and pushing the hydraulic oil inside the cavity 124 upwards, so that the hydraulic oil can enter the circulation tube 13 through the inlet and outlet ends, and then flow into the bag 131 through the circulation tube 13. When a large amount of hydraulic oil enters the bag 131, the deflated bag 131 is propped up, so that the outer wall of the bag 131 is tightly fitted with the inside of the groove 152, and the hydraulic oil is pressed against the inner wall of the groove 152. The close fit increases the friction and contact area between the bag 131 and the connecting tube 51, thereby enhancing the fixing effect of the bag 131 on the connecting tube 51, making the connection more firm and reliable, and effectively preventing the connecting tube 51 from loosening or falling off during subsequent use. At the same time, the vibration generated during the motor test can be better absorbed and buffered by the tightly fitting bag 131, reducing the impact of the vibration on the connection between the connecting tube 51 and the quick plug body 11, ensuring that the connection remains stable under various working conditions.

[0045] Since the shell of the fixing sleeve 12 is transparent, the operator stops pulling the adjusting tube 121 by observing the push of the hydraulic oil on the movable plate 151, and can accurately control the filling degree of the bladder 131 according to actual needs, thereby achieving precise adjustment of the fixing degree of the connecting tube 51 and preventing the problem of overfilling or underfilling. At this time, the adjusting tube 121 is rotated to make the strip magnetic plate 136 drive the sealing block 133 to seal the inlet and outlet of the circulation tube 13 again, effectively preventing the hydraulic oil inside the circulation tube 13 from flowing out. The good sealing performance ensures the stability of the hydraulic oil pressure in the bladder 131 and maintains the fixing effect of the bladder 131 on the connecting tube 51.

[0046] The pressure sensor 16 provided inside the quick plug body 11 monitors the pressure changes in the water channel in real time. When there is a leak at the connection of the quick plug body 11, the pressure in the water channel will gradually drop. The pressure sensor 16 converts the detected information into an electrical signal and transmits it to the test computer, so that the operator can judge whether there is a leak and the extent of the leak by observing the rate and amplitude of the pressure drop on the computer. A temperature sensor 17 disposed within the quick-plug body 11 measures the temperature of the fluid within the quick-plug body 11 by directly contacting the fluid therein. The temperature sensor 17 converts the temperature signal into an electrical signal and transmits it to a test computer. Real-time temperature monitoring allows timely detection of overheating in the waterway system, preventing motor damage or cooling system failure caused by excessive temperature.

[0047] By setting the flow sensor 126, the flow rate of the liquid inside the quick plug body 11 can be converted into an electrical signal and transmitted to the test computer. When the flow rate is lower than the set range, the operator pulls the regulating tube 121 to adjust it. Through this real-time monitoring and adjustment mechanism, it can quickly respond to flow changes to ensure that the liquid flow rate always remains within the set range, meet strict test standards, and improve the accuracy and reliability of the test results. When the regulating tube 121 moves upward, since the fixed rod 122 remains stationary, the upward movement of the regulating tube 121 will squeeze the hydraulic oil below the top plate of the fixed rod 122 inside the cavity 2 125. At this time, the hydraulic oil is squeezed and presses the top plate of the fixed rod 122 The circular hole is punched open, allowing the hydraulic oil to move upward through the circular hole. At this time, the hydraulic oil inside the cavity 124 is subjected to the extrusion force, pushing the movable plate 151 to move downward, causing the blocking rod three 153 to leave the interior of the movable plate 151, so that the hydraulic oil can move downward through the movable plate 151. When the movement of the regulating tube 121 is stopped, the movable plate 151 can be pushed to return to its original position under the action of the balance spring 154 and the smooth spring 2 155. When the hydraulic oil flows through the circular hole and the movable plate 151, the upward movement speed of the regulating tube 121 can be slowed down. This slow movement makes it easier for the operator to adjust the flow rate more finely, prevents excessive flow fluctuations due to too fast adjustment, and further improves the accuracy of flow control.

[0048] It should be noted that a rubber ring is provided inside the circular hole on the top plate. When the rubber ring is pushed by the hydraulic oil, it will open, so that the hydraulic pressure will flow through the circular hole. When the regulating tube 121 is not subjected to the upward or downward force of the operator, the regulating tube 121 will remain stationary.

[0049] It should be noted that pressing the regulating tube 121 downward reduces the flow rate of the liquid.

[0050] The operator removes the sealing block 133 again to release the blockage of the circulation tube 13, and then pushes the regulating tube 121 downward to create a gap above the cavity 124. The operator then pulls the connecting tube 51. When the connecting tube 51 is forced to move, the inner wall of the groove 1 52 and the bladder 131 are squeezed, so that the hydraulic oil inside the bladder 131 re-enters the interior of the cavity 124 from the circulation tube 13. After losing the hydraulic oil, the bladder 131 becomes deflated, making it easier for the connecting tube 51 to be pulled out from the interior of the quick connector body 11.

[0051] When the operator pulls the connecting tube 51 out of the quick plug body 11, the mounting groove 14 loses its driving force. At this time, the return spring 143 pushes the mounting groove 14 toward the outside of the quick plug body 11. When the mounting groove 14 drives the filter 141 to move to one end of the quick plug body 11, the mounting groove 14 and the filter 141 are in movable contact, making it easy for the operator to remove the filter 141 from the mounting groove 14, thereby replacing or cleaning the filter 141. This avoids the filter 141 being too deep inside the quick plug body 11 to be easily replaced or cleaned by the operator. Accordingly, the return spring 143 pushes the filter 141 to one end of the quick plug body 11, making it easy for the operator to replace or clean it.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
