Description

A motor test load simulation device Technical Field

[0001] This utility model relates to the technical field of motor testing equipment, specifically a motor testing load simulation device. Background Technology

[0002] As an indispensable power device in modern industrial applications, the performance testing of electric motors is crucial to ensuring their reliability and durability under various operating environments. Traditional motor load testing methods are typically conducted under ambient temperature conditions, which cannot simulate the impact of extreme temperature conditions (such as high or low temperatures) on motor performance. However, in practical applications, motors may face a variety of different operating environments, including extremely cold or hot climatic conditions, all of which can affect the motor's efficiency and lifespan.

[0003] Existing motor testing equipment has certain limitations. Many traditional motor load testing devices lack effective heating or cooling mechanisms and can only perform tests at or near room temperature. This cannot meet the needs of performance evaluation of motors in extreme temperature environments. For example, motors operating in extremely cold regions need to be able to start and run at low temperatures, while motors operating in high-temperature environments need to ensure their heat dissipation capacity and material stability. Therefore, a motor test load simulation device is needed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a motor test load simulation device, which has the advantages of rapid heating and cooling, uniform and stable temperature, and convenient operation, and solves the problem that motor test load simulation devices cannot simulate extreme temperature environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor test load simulation device, comprising a support mechanism, a load tester and a motor body, wherein a heat preservation mechanism is provided at the upper end of the support mechanism and a temperature adjustment mechanism that cooperates with the heat preservation mechanism is provided at the lower end of the support mechanism;

[0006] The support mechanism includes a testing platform and a motor mounting bracket. The motor body is fixedly mounted on the motor mounting bracket. An air inlet and an air outlet are provided on the upper surface of the testing platform near the motor mounting bracket. The insulation mechanism includes an insulation cover and fixing bolts. The insulation cover is fitted onto the upper end of the motor body and rotatably connected to the testing platform. The insulation cover is fixed to the motor mounting bracket by the fixing bolts. The temperature control mechanism includes a sealed box, an electric heating wire fan, and a cooler. The sealed box is installed at the lower end of the air inlet and air outlet. The electric heating wire is installed inside the sealed box. The cooler is fixedly installed at the bottom of the sealed box.

[0007] As a preferred embodiment of the motor test load simulation device of this utility model, a heat exchange plate is provided on the upper bottom surface of the sealed box, and the heating wire is fixedly installed on the heat exchange plate.

[0008] As a preferred embodiment of the motor test load simulation device of this utility model, the fan is fixedly installed at the lower end of the air inlet and air outlet, and the airflow direction of the fan at the lower end of the air inlet and air outlet is opposite.

[0009] As a preferred embodiment of the motor test load simulation device of this utility model, the side wall of the heat insulation cover is provided with a heat insulation cavity.

[0010] As a preferred embodiment of the motor test load simulation device of this utility model, a first rotating shaft is provided at the bottom of the end of the heat insulation cover away from the fixing bolt, and the heat insulation cover is rotatably connected to the test table through the first rotating shaft.

[0011] As a preferred embodiment of the motor test load simulation device of this utility model, the heat insulation cover is provided with a collar, the fixing bolt is installed on the collar and rotatably connected thereto, the upper end face of the motor fixing bracket is provided with a screw hole that mates with the fixing bolt, and the top of the fixing bolt is provided with a knob.

[0012] As a preferred embodiment of the motor test load simulation device of this utility model, the side end face of the heat insulation cover is provided with a first sliding groove, the front and rear sides of the collar are provided with second rotating shafts, and the side wall of the first sliding groove is provided with a second sliding groove that movably cooperates with the first rotating shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses an electric heating wire and a cooler in the temperature control mechanism, combined with the structural design of a sealed box and a heat exchange plate, which can quickly heat or cool the air. It also forms a bidirectional airflow circulation through the fans at the air inlet and air outlet. The opposite airflow direction of the fans at the air inlet and air outlet accelerates the heat exchange efficiency between the air inside the heat insulation cover and the sealed box, ensuring that the temperature around the motor body is uniform and stable. This structure solves the problem that the ambient temperature cannot be adjusted in traditional motor load testing, making it inconvenient to test the load performance of the motor under extreme high or low temperature conditions.

[0015] 2. The heat insulation cover of this utility model is rotatably connected to the test platform through the first rotating shaft, which enables it to open and close quickly, facilitating the installation and maintenance of the motor body. At the same time, the design of the collar and the fixing bolt allows the heat insulation cover to be fixed with a single bolt, and the knob structure does not require the use of tools. The sliding fit design of the second rotating shaft of the collar and the second sliding groove solves the pain points of cumbersome disassembly and assembly and low efficiency of traditional testing equipment, while reducing the risk of component loss.

[0023] Please refer to Figures 1-6. A motor test load simulation device includes a support mechanism 1, a load tester 2, and a motor body 3. The upper end of the support mechanism 1 is provided with a heat preservation mechanism 4, and the lower end of the support mechanism 1 is provided with a temperature adjustment mechanism 5 that cooperates with the heat preservation mechanism 4.

[0024] The support mechanism 1 includes a testing platform 101 and a motor mounting bracket 102. The motor body 3 is fixedly installed on the motor mounting bracket 102. An air inlet 103 and an air outlet 104 are provided on the upper surface of the testing platform 101 near the motor mounting bracket 102. The heat preservation mechanism 4 includes a heat preservation cover 401 and fixing bolts 402. The heat preservation cover 401 is sleeved on the upper end of the motor body 3 and rotatably connected to the testing platform 101. The heat preservation cover 401 is fixed to the motor mounting bracket 102 by fixing bolts 402. The temperature control mechanism 5 includes a sealed box 501, a heating wire 502, a fan 503, and a cooler 505. The sealed box 501 is installed at the lower end of the air inlet 103 and the air outlet 104. The heating wire 502 is installed inside the sealed box 501. The cooler 505 is fixedly installed at the bottom of the sealed box 501.

[0025] Furthermore, a heat exchange plate 5011 is provided on the upper bottom surface of the sealed box 501, and an electric heating wire 502 is fixedly installed on the heat exchange plate 5011.

[0026] Heating the heat exchange plate 5011 by heating the heating wire 502 increases the heat exchange area between the heating wire 502 and the air, rapidly raising the temperature inside the sealed box 501 and the insulation cover 401. This allows for testing the ultimate load of the motor body 3 under high-temperature conditions. When testing the ultimate load at low temperatures, the heating wire 502 is turned off, and the cooler 505 is started. The cooler 505 cools the air, and the heat exchange plate 5011 cools the air, thus simulating the winter operating environment and testing the low-temperature load of the motor.

[0027] Furthermore, the fan 503 is fixedly installed at the lower end of the air inlet 103 and the air outlet 104, and the airflow direction of the fan 503 at the lower end of the air inlet 103 and the air outlet 104 is opposite.

[0028] Two sets of fans 503 blow air and draw air into the insulation cover 401 from the lower ends of the air inlet 103 and the air outlet 104, respectively, thereby circulating the air in the insulation cover 401 and the sealed box 501 and improving the temperature uniformity inside the insulation cover 401.

[0029] Furthermore, the side wall of the heat insulation cover 401 is provided with a heat insulation cavity 4011, and a temperature sensor is provided at the lower end of the heat insulation cover 401.

[0030] The heat insulation cavity 4011 reduces the heat conduction efficiency of the heat insulation cover 401, thereby preventing the heat insulation cover 401 from dissipating heat too quickly, which would lead to excessive power consumption of the equipment. At the same time, it also prevents the heat insulation cover from overheating and burning the user.

[0031] Furthermore, a first rotating shaft 403 is provided at the bottom of the end of the heat insulation cover 401 away from the fixing bolt 402, and the heat insulation cover 401 is rotatably connected to the testing table 101 through the first rotating shaft 403.

[0032] The rotating heat insulation cover 401 structure allows it to open and close quickly along the first rotating shaft 403, which facilitates the installation and disassembly of the internal motor body 3 and improves the equipment testing efficiency.

[0033] Furthermore, the heat insulation cover 401 is provided with a collar 404, and the fixing bolt 402 is installed on the collar 404 and rotatably connected to it. The upper end face of the motor mounting bracket 102 is provided with a screw hole 1021 that mates with the fixing bolt 402, and the top of the fixing bolt 402 is provided with a knob.

[0034] The insulation cover 401 is fixed to the motor mounting bracket 102 by fixing bolts 402. A single bolt can quickly fix the insulation cover 401, and with the knob, no external tools are needed, which greatly improves the convenience of installation.

[0035] Furthermore, the side end face of the heat insulation cover 401 is provided with a first sliding groove 4012, the front and rear sides of the collar 404 are provided with a second rotating shaft 4041, and the side wall of the first sliding groove 4012 is provided with a second sliding groove 4013 that is movably engaged with the first rotating shaft 403.

[0036] The collar 404 can slide within the second groove 4013 via the second rotating shaft 4041, and can also rotate around the second rotating shaft 4041. This avoids interference between the bolt and the motor mounting bracket 102 when the insulation cover 401 is closed, preventing deformation of the insulation cover 401 and improving the stability of the insulation cover 401. Furthermore, when the insulation cover 401 is opened, the fixing bolt 402 remains on the insulation cover 401, preventing bolt loss.

[0037] In use, the motor body 3 is first fixedly mounted on the motor mounting bracket 102. Then, the insulation cover 401 is rotated clockwise around the first rotating shaft 403 to fit over the upper end of the motor body 3. Next, the fixing bolts 402 on the collar 404 are tightened by engaging the screw holes 1021 on the motor mounting bracket 102. The insulation cover 401 can be fixed using a knob without external tools. When testing the ultimate load of the motor body 3 under high-temperature conditions, the heating wire 502 in the temperature control mechanism 5 is activated. The heating wire 502 heats the heat exchange plate 5011, increasing the heat exchange area with the air and rapidly raising the temperature inside the sealed box 501 and the insulation cover 401. Simultaneously, the lower ends of the air inlet 103 and the air outlet 104... Two sets of fans 503 with opposite wind directions blow and exhaust air into the insulation cover 401, circulating the air between the insulation cover 401 and the sealed box 501 to ensure temperature uniformity within the insulation cover 401. When it is necessary to test the ultimate load at low temperatures, the heating wire 502 is turned off and the cooler 505 is started. The cooler 505 cools the air through the heat exchange plate 5011 to simulate the winter usage environment. Throughout the process, the heat insulation cavity 4011 on the side wall of the insulation cover 401 reduces the heat conduction efficiency to prevent the insulation cover 401 from dissipating heat too quickly, the equipment from consuming too much power, and the user from being burned. After the equipment is used, turn the knob to loosen the fixing bolt 402, and then open the insulation cover 401 along the first rotating shaft 403 to easily disassemble the internal motor body 3.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
