Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pressure regulating devices, and specifically relates to an auxiliary pressure regulating device. Background Technology
[0002] China has made some progress in the safety performance testing of home appliances under abnormal conditions. However, most tests of home appliances (such as indoor heaters and hair dryers) still rely on traditional methods, such as manually adjusting the voltage and having testing personnel on-site in real time. These methods are inefficient and lack precision. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an auxiliary pressure regulating device. The specific technical solution is as follows: The aforementioned auxiliary voltage regulating device includes: A base, wherein the base is divided into a first mounting area and a second mounting area; An adjustable power supply is located in the first installation area; A DC stepper motor is installed in the second mounting area, and the output rotor of the DC stepper motor is connected to the output rotor of the adjustable power supply via a synchronous belt drive. A voltage sensor is disposed in the second mounting area; A current sensor is disposed in the second mounting area; The main control panel is located on the side of the second mounting area away from the first mounting area, and the main control panel is electrically connected to the voltage sensor and the current sensor.
[0004] Furthermore, a bracket is provided in the middle of the second installation area, and the DC stepper motor is mounted on the bracket.
[0005] Furthermore, a guide rail is provided in the second installation area, the guide rail is laid along the length direction of the base, and the voltage sensor and current sensor are mounted on the guide rail.
[0006] Furthermore, corner brackets are provided at the two end corners of the second installation area away from the first installation area, and inclined blocks are provided on the opposite sides of the two corner brackets. The two sides of the main control panel are secured to the two inclined blocks.
[0007] Furthermore, the top of the main control panel has reserved wiring terminals for connecting the data transmission lines of the voltage sensor and the current sensor, as well as the control line of the DC stepper motor.
[0008] Furthermore, the adjustable power supply has four terminals: a power input live wire, a power input neutral wire, a voltage output live wire, and a voltage output neutral wire. The voltage output live wire and the voltage output neutral wire are connected to the voltage acquisition terminal of the voltage sensor.
[0009] Furthermore, limiting angles are set at all four corners of the first installation area to limit the DC stepper motor.
[0010] Compared with the prior art, the present invention has the following advantages: (1) Automation of the testing process: Traditional manual voltage adjustment has many drawbacks, such as low efficiency and susceptibility to subjective factors. The device in this application uses a motor drive to replace manual voltage adjustment, realizing automatic alarm and automatic voltage adjustment functions of the testing equipment, which greatly reduces the interference of human factors on the test results. In addition, automated operation makes the test more standardized and uniform, which helps to improve work efficiency and consistency of results.
[0011] (2) Precise voltage control: Since the power of the sample under test fluctuates during the test, it may cause fluctuations in the power supply voltage. The device in this application can effectively improve the stability and accuracy of voltage control through continuous feedback adjustment. Compared with the traditional open-loop control system, this method can not only better adapt to load changes, but also significantly reduce the output fluctuation range, ensuring that the test conditions are always in an ideal state.
[0012] (3) The test data traceability system has data storage and output functions, which can save relevant test data in the testing process and realize the visualization and traceability of test data. This is of great significance for product quality tracking, fault diagnosis and subsequent improvement. Users can view historical records through simple operations to understand the specific situation of each test link, so as to make more scientific and reasonable decisions. Attached Figure Description

Detailed Implementation
[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0016] like Figures 1-4 As shown, an auxiliary voltage regulating device includes a base 102, which is divided into a first mounting area and a second mounting area. The first mounting area is equipped with an adjustable power supply 101. The second mounting area is equipped with a DC stepper motor 107, a voltage sensor 104, a current sensor 105, and a main control panel 106. The output rotor of the DC stepper motor 107 is connected to the output rotor of the adjustable power supply 101 via a synchronous belt 110. Specifically, a synchronous pulley I 109 is mounted on the output rotor of the DC stepper motor 107, and a synchronous pulley II 111 is mounted on the output rotor of the adjustable power supply 101. The synchronous pulleys I 109 and II 111 are connected via the synchronous belt 110. The main control panel 106 is located on the side of the second mounting area away from the first mounting area and is electrically connected to the voltage sensor 104 and the current sensor 105. Specifically, the top of the main control panel 106 has pre-installed terminals for connecting the data transmission lines of the voltage sensor 104 and the current sensor 105, as well as the control lines of the DC stepper motor 107. The adjustable power supply 101 has four terminals: power input live wire, power input neutral wire, voltage output live wire, and voltage output neutral wire. The voltage output live wire and voltage output neutral wire are connected to the voltage acquisition terminal of the voltage sensor 104.
[0017] Continue reading Figure 4It is known that a bracket 108 is set in the middle of the second installation area, and a DC stepper motor 107 is mounted on the motor bracket 108. In this embodiment, the motor bracket 108 includes a mounting column fixed to the base 102 and an L-shaped frame set on the mounting column. The DC stepper motor 107 is mounted in the L-shaped frame. A guide rail 103 is also set in the second installation area. The guide rail 103 is laid along the length direction of the base 102. The voltage sensor 104 and the current sensor 105 are mounted on the guide rail 103, and the voltage sensor 104 and the current sensor 105 can move linearly along the guide rail 103, which is convenient for operation. Corner brackets are set at the two corners on the side of the second installation area away from the first installation area. Angled blocks are set on the opposite sides of the two corner brackets. The two sides of the main control panel 106 are clamped on the two angled blocks, which not only facilitates the installation and fixation of the main control panel 106, but also facilitates the observation of the display effect on the main control panel 106.
[0018] In this application, limit angles 114 are set at the four corners of the first installation area to limit the DC stepper motor 107.
[0019] In use, the output voltage of the adjustable power supply 101 is adjusted via a DC stepper motor 107. This means that motor drive and voltage sensor feedback correction replace manual control of the adjustable power supply 101's output voltage. Through feedback from instrument parameters, the speed and direction of the DC stepper motor 107 are precisely adjusted, thereby achieving forward and reverse adjustment of the output voltage and ensuring its stability and accuracy. Simultaneously, the current sensor 105 collects data in real time, monitoring the current to achieve automatic start and stop control of the DC stepper motor 107. When the current in the circuit is detected to be 0, the DC stepper motor 107 stops, ensuring that the adjustable power supply 101 maintains its current voltage output state until the power output stabilizes.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
