Description

Technical Field

[0001] This utility model relates to the field of power quality detection technology, and more specifically, to a power quality detection device. Background Technology

[0002] Currently, handheld power quality detectors are widely used in the operation and maintenance of power distribution systems, as their portability facilitates on-site detection of parameters such as voltage, harmonics, and flicker in distribution cabinets. However, they also have certain shortcomings in practical operation: First, during testing, the equipment needs to be suspended from the door panel of the distribution cabinet for wiring operations. Existing equipment mostly relies on simple hooks or magnetic structures for fixation. When technicians rotate the buttons on the equipment panel or switch test gears, external forces can easily cause the equipment to shake or even fall off, resulting in test interruption or poor contact. Second, the space in the distribution cabinet is small, and the testing process requires frequent operation of the equipment interface. Traditional suspension methods cannot provide operational freedom while ensuring stability, and shaking may affect the accuracy of test data. Utility Model Content

[0003] The purpose of this utility model is to address the problem that existing power quality testing devices often rely on simple hooks or magnetic structures for fixation.

[0006] As a preferred technical solution of this application, a support frame is installed on the back of the device body, and an adapter groove is provided on the back of the device body near the support frame. A hand grip groove is provided at the outer edge of the adapter groove, and a hinge is provided between the support frame and the adapter groove.

[0007] As a preferred technical solution of this application, the display screen is connected to the main body of the device by bolts, the number of control buttons is several groups and they are arranged in an array, the control circuit board and the battery are arranged in the middle of the main body of the device, and the control circuit board and the battery are electrically connected.

[0008] As a preferred technical solution of this application, the number of anti-drop sleeves is two sets and they are symmetrically distributed, and the anti-drop sleeves are made of rubber.

[0009] As a preferred technical solution of this application, both the upper support plate and the lower support plate are integral with the main body of the device, and the corners of the lower support plate and the upper support plate are rounded.

[0010] As a preferred technical solution of this application, the output end of the electric telescopic rod is adapted to the moving hole, the pressure sensor, the electric telescopic rod and the infrared sensor are all electrically connected to the control circuit board, the guide rod is adapted to the guide hole, and the anti-slip strip is made of rubber.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: By setting up a fixing component, when the main body of the device needs to be clamped and fixed, the edge of the cabinet door of the power distribution cabinet is locked between the upper support plate and the compression fixing plate. The infrared sensor detects the change in distance and feeds it back to the control circuit board. Then, the output end of the electric telescopic rod is controlled to move along the inside of the moving hole, which drives the pressure sensor and the compression fixing plate to clamp the cabinet door.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] like Figures 1-4 As shown, this embodiment proposes a power quality detection device, including a device body 1, a display screen 2 and control buttons 3 at the upper end of the device body 1, a drop-proof protective sleeve 4 on the outside of the device body 1, a communication connector 5 on one side of the device body 1, and a handrail 6 and fixing components 7 on the outside of the device body 1. The fixing component 7 includes an upper support plate 71 and a lower support plate 72 fixed to one side of the main body 1, a moving hole 73 and a guide hole 74 opened in the middle of the lower support plate 72, an electric telescopic rod 75 fixed to one side of the lower support plate 72, a pressure sensor 76 connected to the output end of the electric telescopic rod 75, a compression fixing plate 77 provided on one side of the pressure sensor 76, a guide rod 78 provided on the outside of the compression fixing plate 77, an anti-slip strip 79 provided on one side of the compression fixing plate 77 and the upper support plate 71, and an infrared sensor 710 installed in the middle of the upper support plate 71.

[0018] A support frame 8 is installed on the back of the main body 1, and an adapter groove is provided on the side of the back of the main body 1 near the support frame 8. A hand grip groove is provided at the outer edge of the adapter groove. A hinge is provided between the support frame 8 and the adapter groove, which facilitates the folding and extension of the support frame 8 and makes it convenient to support the main body 1.

[0019] The display screen 2 is connected to the main body 1 of the device by bolts. There are several groups of control buttons 3 arranged in an array. The control circuit board and battery are located in the middle of the main body 1, and the control circuit board and battery are electrically connected, which is conducive to the control of the fixed component 7 and the detection of parameters such as voltage, harmonics and flicker by the power distribution cabinet.

[0020] There are two sets of anti-fall protective sleeves 4, which are symmetrically distributed. The anti-fall protective sleeves 4 are made of rubber and have a protective effect. They can provide protection and cushioning during the fall of the main body 1 of the device.

[0021] Both the upper support plate 71 and the lower support plate 72 are integral with the main body 1 of the device, and the corners of the lower support plate 72 and the upper support plate 71 are rounded, with a certain curvature, so that there will be no scratching during the carrying process.

[0022] The output end of the electric telescopic rod 75 is adapted to the moving hole 73. The pressure sensor 76, the electric telescopic rod 75 and the infrared sensor 710 are all electrically connected to the control circuit board. The guide rod 78 is adapted to the guide hole 74. The anti-slip strip 79 is made of rubber and can automatically clamp the main body 1 of the device to the edge of the distribution cabinet.

[0023] In summary, the working principle of this utility model is as follows: When in use, the fixing component 7 on one side of the main body 1 of the device is clipped onto one side of the power distribution cabinet. The clamping force is set by the control button 3, and the device body 1 is automatically clamped and fixed, which facilitates the subsequent connection of the communication connector 5 to the corresponding connection line for detecting parameters such as voltage, harmonics, and flicker of the power distribution cabinet.

[0024] It should be noted that, through the setting of the fixing component 7, when the main body 1 of the device needs to be clamped and fixed, the edge of the cabinet door of the distribution cabinet is stuck between the upper support plate 71 and the compression fixing plate 77. The pressure range value of the pressure sensor 76 is set by the control button 3. When the cabinet door is inserted between the upper support plate 71 and the compression fixing plate 77, the infrared sensor 710 detects the change in distance and feeds it back to the control circuit board. Then, the output end of the electric telescopic rod 75 is controlled to move along the inside of the moving hole 73, driving the pressure sensor 76 and the compression fixing plate 77 to clamp the cabinet door. At the same time, the guide rod 78 is driven to slide along the inside of the guide hole 74 to ensure stability. Then, the cabinet door is clamped by the compression fixing plate 77 and the upper support plate 71. The pressure sensor 76 detects the clamping force. After reaching the set value, it feeds back to the control circuit board and controls the output end of the electric telescopic rod 75 to stop running, thereby automatically clamping the main body 1 of the device on the outside of the cabinet door.

[0025] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
