Description

Technical Field

[0001] This utility model relates to the field of measurement technology for new energy equipment, and in particular to a measuring instrument for new energy equipment. Background Technology

[0002] Electric motors are core power components in industrial production, transportation, smart homes, and other fields. Their performance and quality directly affect the operating efficiency and safety stability of equipment. As motor technology develops towards higher efficiency, miniaturization, and intelligence, the demand for precise testing of key parameters such as speed, torque, power, and temperature rise is increasingly prominent. Professional motor test benches have become essential equipment for comprehensive performance evaluation. Motor test benches need to cover motor production quality control and R&D stages, undertaking multi-parameter simultaneous testing tasks. Currently mainstream integrated motor test benches integrate data acquisition, analysis, and storage functions, are adaptable to motors of different specifications and models, and provide reliable data support for motor performance verification through standardized testing procedures. This ensures the stable operation of motors in various application scenarios and is an indispensable technical equipment in the development of the modern motor industry.

[0003] Existing new energy motor test benches have significant limitations in operating condition simulation testing: Because different simulation scenarios require specific functional equipment, frequent replacements of hardware such as loading devices and data acquisition modules are necessary during testing. These replacements require shutdown for disassembly, reassembly, and recalibration, which not only prolongs the testing cycle and reduces overall efficiency but also easily leads to data inconsistency under different operating conditions due to equipment connection deviations, affecting the accuracy of test results. Furthermore, the switching and maintenance of multiple devices increases the equipment investment costs and operational complexity for enterprises, making it difficult to adapt to the diverse operating condition testing needs of new energy motors.

Therefore, they should not be construed as limitations on this utility model.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0027] To address the problems existing in the background art, this application proposes the following technical solution:

[0028] In this utility model, such as Figure 1 , Figure 2 , Figure 3 As shown, a measuring instrument for new energy equipment includes a mounting base plate 1 and a simulation box 7 fixedly mounted on the mounting base plate 1. A torque sensor 3 is provided on the outer wall of the simulation box 7 near one side. The torque sensor 3 is located above the mounting base plate 1 and a first support seat 2 is provided between the torque sensor 3 and the mounting base plate 1. The mounting base plate 1 and the torque sensor 3 are fixedly connected by the first support seat 2. A support cross plate 18 is fixedly connected between two opposite inner side walls inside the simulation box 7. A test motor 5 with a main shaft coaxial with the main shaft of the torque sensor is fixedly connected to the support cross plate 18. A transmission shaft 4 is provided between the test motor 5 and the torque sensor 3, penetrating the side wall of the simulation box 7 and fixedly connected at both ends to the main shaft of the torque sensor 3 and the main shaft of the test motor 5 respectively by couplings. Temperature simulation components are provided on the inner side wall of the simulation box 7 except for the side of the box opening. Water spray simulation components are provided on the top and bottom outer walls of the simulation box 7. Heat circulation components are provided on the outer side walls of the simulation box 7 near the top and bottom.

[0029] In this technical solution, the mounting base plate 1 serves as the fundamental load-bearing component of the entire measuring instrument, providing a stable and flat mounting platform for all components above, effectively preventing positional shifts of components due to unstable foundations and ensuring the overall stability of the equipment operation. The simulation chamber 7 constructs a relatively enclosed test space, reducing interference from external environmental factors on the internal testing process and creating a controllable testing environment for the motor under test 5. The torque sensor 3 is fixed above the mounting base plate 1 via the first support seat 2. This setup not only accurately positions the torque sensor 3 but also ensures that it remains coaxial with the main shaft of the motor under test 5, fundamentally reducing measurement errors caused by shaft misalignment and improving the accuracy of torque data acquisition. The support plate 18 inside the simulation chamber 7 provides stable support for the motor under test 5, preventing the motor from shaking or shifting during operation and further ensuring the stability of power transmission. The cooperation between the transmission shaft 4 and the coupling enables efficient and lossless power transmission between the motor under test 5 and the torque sensor 3, ensuring that the motor's operating status is accurately reflected in the measurement data of the torque sensor 3. The temperature simulation component, water spray simulation component, and thermal circulation component are also included.

[0030] For the part where the drive shaft 4 contacts the simulation box 7, it is recommended to use a ceramic sealing ring.

[0031] In this utility model, such as Figure 1 , Figure 2 , Figure 4 As shown, the temperature simulation component includes a coil 16 that is horizontally wound and fixedly connected to the inner wall of the simulation chamber 7. Horizontally distributed heat-conducting plates 17 are fixedly connected to the arc surface of the coil 16 away from the inner wall of the simulation chamber 7. A heat insulation layer 15 is fixedly installed on the inner wall of the simulation chamber 7 where the coil 16 is located.

[0032] In this technical solution, the coil 16 in the temperature simulation component is fixed to the inner wall of the simulation chamber 7 in a horizontal coiling manner. This structure maximizes the contact area between the coil 16 and the air inside the simulation chamber 7, making the heat exchange more thorough and uniform, and avoiding excessive local temperature differences within the chamber that could affect the test results. The horizontal heat-conducting plate 17 fixed on the arc surface of the coil 16 further expands the heat transfer carrier, enabling the heat from the coil 16 to be quickly and evenly transferred to the surrounding air, significantly accelerating the rate of temperature adjustment within the simulation chamber 7, shortening the time to reach the target test temperature, and improving test efficiency. At the same time, the heat insulation layer 15 installed on the inner wall of the simulation chamber 7 effectively blocks heat exchange between the inside and outside of the chamber. On the one hand, it reduces the interference of the external ambient temperature on the test environment inside the chamber, ensuring that the temperature inside the chamber can be stably maintained within the set range, thus guaranteeing the accuracy of the temperature simulation. On the other hand, it also reduces energy loss. For example, when maintaining high or low temperature environments, it reduces the loss of heat and cold energy to the outside, saving equipment operating energy consumption, improving the energy efficiency and environmental friendliness of the equipment, and effectively reducing test costs in the long term.

[0033] The coil 16 can be made of stainless steel or copper, the heat-conducting plate 17 is recommended to be made of aluminum material that has been treated for rust prevention and high temperature resistance, and the insulation layer can be made of rigid polyurethane board.

[0034] In this utility model, such as Figure 1 , Figure 2 As shown, the water shower assembly includes an inlet pipe 13 fixedly installed at the top center of the simulation box 7 and an outlet pipe located at the bottom center of the simulation box 7. The inlet pipe 13 extends vertically downwards into the interior of the simulation box 7, and an outlet 6 is fixedly connected to the pipe opening at the inlet end, with a spray nozzle 14 facing the motor 5 under test. The outlet pipe is fixedly connected to the bottom outer wall of the simulation box 7 and communicates with the interior of the simulation box 7.

[0035] In this technical solution, in the water spray assembly, the water inlet pipe 13 is fixed at the top center of the simulation chamber 7, and the water outlet 6 of the spray nozzle 14 faces the motor under test 5. This layout ensures that the water flow is more concentrated on the motor under test 5 during spraying, simulating the scenario of rainwater directly hitting the motor in a rainy environment, making the water spray test more targeted. The water inlet pipe 13 penetrates vertically downwards into the interior of the simulation chamber 7, which can reduce water loss during transmission, ensure stable spray pressure, and facilitate adjustment of spray intensity to simulate environments with different rainfall levels. The water outlet pipe located at the bottom center of the simulation chamber 7 can promptly drain the water inside the chamber, preventing water accumulation. This prevents water from soaking the motor or other components and causing equipment damage, ensuring the safety of the testing process. It also prevents water accumulation from affecting the humidity or temperature environment inside the chamber, ensuring that subsequent tests can be conducted in a clean and controllable environment. Through the synergistic effect of the water spray components, the waterproof performance, insulation performance and operational stability of the tested motor 5 can be comprehensively tested, providing direct test basis for optimizing the waterproof structure of the motor and ensuring that the motor can operate safely and reliably in actual rainy or humid conditions.

[0036] In this utility model, such as Figure 1 , Figure 3 As shown, the heat circulation assembly includes an air inlet 12 fixedly installed on the top outer wall of the simulation box 7 and a return air inlet 8 fixedly installed near the bottom outer wall of the simulation box 7. A water-air separator 9 is provided on the side near the return air inlet 8, located outside the simulation box 7, and a fan 11 is provided on the side near the air inlet 12, located outside the simulation box 7. The return air inlet 8, the water separator, the fan 11, and the air inlet 12 are connected in sequence by pipes.

[0037] In this technical solution, the air inlet 12 of the heat circulation component is located on the top outer wall of the simulation chamber 7, and the return air inlet 8 is located near the bottom outer wall. This vertical distribution conforms to the airflow law, allowing the airflow to form a more complete and uniform circulation path within the simulation chamber 7, avoiding dead air zones and ensuring uniform temperature and humidity distribution in all areas of the chamber. The fan 11 provides power for airflow circulation, accelerating airflow speed, promoting heat exchange within the chamber, further improving the efficiency and uniformity of temperature regulation, and enabling the simulation chamber 7 to reach the set test environment parameters more quickly. The water-air separator 9 installed at the return air inlet 8 can dehumidify the circulating air flowing out of the chamber, effectively removing moisture from the air. On the one hand, this prevents high humidity air from entering the fan 11 and causing damage due to moisture, extending the service life of the fan 11; on the other hand, it prevents humid air from re-entering the simulation chamber 7 and affecting the humidity environment inside the chamber, ensuring that humidity parameters remain stable within the set range and avoiding humidity interference with temperature testing or motor performance testing results. The overall design of the thermal cycling components significantly improves the stability and controllability of the environment inside the simulation chamber 7, providing more accurate environmental protection for motor testing and making the test data more reliable.

[0038] Among them, the air distribution plate can be customized and installed at the air inlet 12 according to actual needs, and the louvered water baffle can be customized and installed at the air outlet according to actual needs.

[0039] In this utility model, such as Figure 3 As shown, the inlet and outlet of the coil 16 both penetrate the side wall opposite to the opening of the simulation chamber 7 and extend outward. A high and low temperature integrated machine 10 is provided on the outside of the simulation chamber 7 near the protruding end of the inlet and outlet of the coil 16. The liquid inlet and liquid return port of the high and low temperature integrated machine 10 are respectively connected to the two ports of the coil 16 through pipes.

[0040] In this technical solution, the inlet and outlet of the coil 16 penetrate the side wall of the simulation chamber 7 and extend outwards. This outward extension facilitates the connection between the coil 16 and the external high and low temperature integrated unit 10, eliminating the need for complex modifications to the internal structure of the simulation chamber 7 and reducing the difficulty of equipment assembly and maintenance. The high and low temperature integrated unit 10, as a professional temperature control device, can stably output liquids at different temperatures. Its inlet and outlet are connected to the two ports of the coil 16 via pipes, forming a complete liquid circulation system. By precisely controlling the temperature and flow rate of the circulating liquid through the high and low temperature integrated unit 10, the temperature of the coil 16 can be accurately adjusted, thereby controlling the ambient temperature inside the simulation chamber 7. Compared to built-in heating or cooling elements, this external high and low temperature integrated unit 10 not only offers a wider temperature adjustment range, meeting various testing needs from low to high temperatures, but also provides higher temperature control accuracy, precisely controlling the rate of temperature change to adapt to the stringent temperature requirements of different motor tests. Meanwhile, placing the core temperature control component (high and low temperature integrated unit 10) outside the simulation chamber 7 facilitates its maintenance and repair without affecting the testing environment inside the simulation chamber 7, thus improving the overall practicality and flexibility of the equipment.

[0041] In this utility model, such as Figure 1 , Figure 2 As shown, two horizontally arranged temperature sensors 19 and humidity sensors 31 are fixedly connected to the outer wall of the simulation box 7, which is adjacent to the side wall of the return air vent 8. The measuring ends of the temperature sensors 19 and humidity sensors 31 extend into the interior of the simulation box 7.

[0042] In this technical solution, temperature sensor 19 and humidity sensor 31 are horizontally fixed to the outer wall of the simulation chamber 7, with their measuring ends extending through into the chamber. This installation method ensures that the sensor measuring ends directly contact the air inside the chamber to obtain real and accurate environmental parameter data, while also avoiding the sensors being completely exposed to the complex environment inside the chamber, reducing damage caused by long-term exposure to high and low temperatures and humidity, and extending the sensor's service life. The two sensors monitor the temperature and humidity inside the simulation chamber 7 in real time and feed back the monitored data to the controller 21 in the form of electrical signals. The controller 21 can analyze and judge the monitoring data according to preset test parameters. When the temperature or humidity inside the chamber deviates from the set value, the controller 21 can promptly issue instructions to adjust the liquid temperature of the high and low temperature integrated unit 10, the speed of the fan 11, or the working state of the water-air separator 9, etc., to achieve dynamic adjustment of the environmental parameters inside the chamber and ensure that the environmental parameters are always stable within the set range. This closed-loop control mode of real-time monitoring and dynamic adjustment significantly improves the automation level of the testing process, reduces the workload of manual monitoring and adjustment, and avoids the lag and error of manual operation, ensuring that motor testing can be carried out in a precise and stable environment, thereby improving the accuracy and reliability of test data.

[0043] The temperature sensor 19 and humidity sensor 31 can be treated to resist humidity and high temperature according to actual needs, or the model that is suitable for this solution can be directly selected.

[0044] In this utility model, such as Figure 2 , Figure 3 As shown, a conduit 30 is fixedly connected to the outer wall of the simulation box 7 on the side opposite to the side where the drive shaft 4 is located. The conduit 30 is vertically inserted into the interior of the simulation box 7 and passes under the support plate 18, and finally passes upward through the support plate 18 and communicates with the inside of the junction box of the motor under test 5.

[0045] In this technical solution, the conduit 30 is fixed to the outer wall of the simulation box 7, opposite to the side where the drive shaft 4 is located. This positioning avoids interference between the conduit 30 and moving parts such as the drive shaft 4 and couplings, ensuring safe operation of the equipment. After the conduit 30 vertically enters the simulation box 7, it passes under the support plate 18 and then passes upward through the support plate 18 to connect with the junction box of the motor under test 5, forming a neat cable laying channel. This wiring method can centrally store the power supply cables and signal cables of the motor under test 5 in the conduit 30, avoiding messy distribution of cables in the simulation box 7. On the one hand, it prevents the cables from contacting the moving parts of the motor and causing wear, or from being wetted by the water spray component and causing short circuit faults, ensuring cable safety and stable power supply to the motor. On the other hand, it avoids messy cables interfering with the airflow inside the box, ensuring that the thermal circulation component can work normally and does not affect the stability of the environmental parameters inside the box. The installation of conduit 30 makes the internal wiring of the simulation box 7 more standardized and neat, improving the overall safety and reliability of the equipment, and also facilitating subsequent inspection and maintenance of the cables.

[0046] The conduit 30 should be made of a material that is heat-insulating and heat-resistant. It should also be noted that the insulation layer of the internal wires should also be made of a heat-resistant material. In order to ensure the long-term stable operation of the equipment, this utility model should be properly grounded and protected against short circuits.

[0047] In this utility model, such as Figure 2 , Figure 3As shown, a door 24 is hinged to the vertical edge of the opening of the simulation box 7 near the side where the wiring conduit 30 is located. An observation window 22 is fixedly installed on the door 24. A movable locking plate 25 parallel to the door 24 is hinged to the end of the door 24 away from the hinge side. Two vertically distributed limiting guide posts 27 are vertically inserted through the movable locking plate 25. The tops of the two limiting guide posts 27 are flange-shaped, and the bottoms of the two limiting guide posts 27 are fixedly connected to a movable locking plate 28 parallel to the movable locking plate 25. Horizontally distributed threaded posts 26 are provided on the movable locking plate 25 between the two limiting guide posts 27. One end of the threaded post 26 is threadedly connected to the movable locking plate 28, and the other end is rotatably connected to the movable locking plate 25 and extends outward. A crank handwheel 23 is fixedly connected to the extended end.

[0048] In this technical solution, the door 24 is hinged to the vertical edge of the opening of the simulation chamber 7, and close to the side where the cable conduit 30 is located. This hinged connection facilitates the opening and closing of the door 24 by the operator, making it convenient to install the motor under test 5 onto the support plate 18 inside the simulation chamber 7, or to inspect and maintain the internal components. The observation window 22 fixed on the door 24 is made of a material that is resistant to high and low temperatures and has good light transmittance. The operator can observe the operating status of the motor under test 5 inside the simulation chamber 7 in real time through the observation window 22 without opening the door 24, such as whether the motor has abnormal vibration, abnormal noise, or leakage, avoiding the disruption of the stable testing environment inside the chamber due to frequent opening of the door 24, and ensuring the continuous and stable testing process. The movable locking plate 25 is hinged to the door 24 and can be flexibly adjusted in angle to facilitate cooperation with the fixed locking plate 29. The limiting guide post 27 on the movable locking plate 25 can limit the movement direction of the movable locking plate 28, ensuring that it can only move in the vertical direction and preventing deviation during the locking process. One end of the threaded post 26 is threadedly connected to the movable locking plate 28, and the other end is rotatably connected to the movable locking plate 25 and equipped with a crank handwheel 23. When the operator turns the crank handwheel 23, the movable locking plate 28 can be moved up and down through the threaded transmission, thereby clamping or loosening the movable locking plate 25 and the movable locking plate 28 against the fixed locking plate 29, thus achieving a tight lock on the chamber door 24. This locking structure is easy to operate, the locking force is adjustable, and it can ensure the sealing between the chamber door 24 and the simulation chamber 7, preventing the leakage of hot or cold air inside the chamber or the entry of outside air, maintaining a stable environment inside the chamber, and also coping with slight pressure changes that may occur inside the simulation chamber 7, ensuring test safety.

[0049] Among them, the side wall of the door 24 facing the inside of the simulation box 7 when in operation can be equipped with a heat insulation layer 15 as needed.

[0050] In this utility model, such as Figure 2 , Figure 3As shown, a fixed locking plate 29 is provided at the vertical edge of the opening of the simulation box 7 on the side where the wiring conduit 30 is located, for cooperating with the movable locking plate 25 and the movable locking plate 28.

[0051] In this technical solution, the fixed locking plate 29 is located at the vertical edge of the opening of the simulation box 7, and is opposite to the side where the cable conduit 30 is located. Its position corresponds to the movable locking plate 1 25 and movable locking plate 28, and is specifically used to cooperate with these two movable locking plates 28 to lock the box door 24. When it is necessary to close the box door 24, the movable locking plate 1 25 is rotated to the position opposite to the fixed locking plate 29. The handwheel 23 drives the movable locking plate 28 to move, so that the movable locking plate 1 25 and movable locking plate 28 clamp the fixed locking plate 29 from both sides, forming a stable locking structure. The fixed locking plate 29 provides a reliable force support point for the movable locking plate 28, ensuring that the locking force can be effectively transmitted to the contact surface between the box door 24 and the simulation box 7, further enhancing the sealing effect of the box door 24. Even when the fan 11 operates inside the simulation chamber 7 and generates a certain airflow pressure, or when temperature changes cause slight deformation of the chamber, this locking structure can still maintain good sealing performance, prevent fluctuations in the environmental parameters inside the chamber, ensure that the testing process is not affected, and improve the overall sealing reliability of the equipment.

[0052] In this utility model, such as Figure 2 , Figure 3 As shown, a controller 21 is located on one side of the opening of the simulation box 7 and near the torque sensor 3. A second support 20 is provided between the controller 21 and the mounting base plate 1, and the controller 21 and the mounting base plate 1 are fixedly connected by the second support 20.

[0053] In this technical solution, the controller 21 is located on one side of the opening of the simulation chamber 7 and close to the torque sensor 3. This layout facilitates wiring connections between the controller 21 and other devices such as the torque sensor 3, temperature sensor 19, humidity sensor 31, high and low temperature integrated unit 10, and fan 11, reducing line length, signal transmission loss and interference, and ensuring the accuracy and timeliness of signal transmission between devices. The controller 21 is fixed to the mounting base 1 by a second support 20. The second support 20 can raise the controller 21 to a suitable height, which on the one hand prevents the controller 21 from directly contacting the mounting base 1, reducing the impact of base plate vibration on the precision electronic components inside the controller 21 and ensuring stable operation of the controller 21; on the other hand, it also facilitates the operator to operate the controller 21, set parameters, and read data, improving operational convenience. As the core control unit of the entire measuring instrument, controller 21 receives signals from various sensors, monitors and stores the operating parameters of the tested motor 5 and the environmental parameters within the simulation chamber 7 in real time, and controls the working status of actuators such as the high and low temperature integrated unit 10, fan 11, and spray nozzle 14 according to preset programs, thus achieving automated control of the testing process. Through controller 21, operators can easily set test parameters, start or stop the test process, view test data, and generate test reports, significantly simplifying the testing operation process, improving testing efficiency, and ensuring that the testing process strictly follows the preset plan, reducing human error.

[0054] The usage method of this embodiment is as follows: Before using this device, first connect the other end of the main shaft of the torque sensor 3 (not connected to the device) to the existing side-powered motor, and connect the water inlet pipe 13 to the existing water supply equipment. Then turn on the power to drive the tested motor 5 to rotate. As the tested motor 5 rotates, the main shaft of the tested motor 5 will drive the transmission shaft 4 to rotate, which in turn drives the torque sensor 3 to rotate. At the same time, when performing environmental condition simulation, the high and low temperature integrated machine 10 can be controlled to supply hot liquid or cold liquid to the coil 16. At the same time, the fan 11 is turned on to blow air into the air inlet 12. The airflow will flow a certain distance in the simulation box 7 and then flow out to the return air outlet 8. During this process, the air flowing out of the air outlet will pass through the water-air separator 9. The water-air separator 9 can help remove moisture from the air in the simulation box 7, and then recirculate back into the simulation box 7 through the air inlet 12. The heat conduction plate 17 and the fan 11 will both To help accelerate the rise or fall of the temperature inside the simulation chamber 7, the user can set the temperature rise or fall. Taking the high and low temperature integrated unit 10 supplying hot liquid as an example, during the process of the high and low temperature integrated unit 10 circulating and supplying cold liquid to the coil 16, the temperature sensor 19 and humidity sensor 31 will also monitor the temperature and humidity inside the simulation chamber 7 in real time and return measurement signals to the controller 21. When the specified temperature is reached, the torque sensor 3 can receive the changes in parameters such as the power of the motor under test 5, and thus determine the impact of the motor under test 5 on this temperature change. If you want to perform a water spray test on the motor under test 5 to simulate environmental conditions such as rain, you can turn on the spray nozzle 14 during this process to simulate and observe the working condition of the motor under test 5 under this influence. The above-mentioned content is the simulation working process of the motor under test 5 in a heated environment. The low temperature simulation working process is the same.

[0055] The torque sensor 3, the motor under test 5, the high and low temperature integrated machine 10, the fan 11, the temperature sensor 19, and the humidity sensor 31 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layout of the torque sensor 3, the motor under test 5, the high and low temperature integrated machine 10, the fan 11, the temperature sensor 19, and the humidity sensor 31 will not be explained in detail.
