Description

Technical Field

[0001] This utility model relates to the field of partial discharge detection technology, specifically a partial discharge detector with a support mechanism. Background Technology

[0002] A partial discharge detector is an instrument used to detect partial discharge phenomena in electrical equipment. When partial discharge occurs in electrical equipment, some of the energy is radiated in the form of ultraviolet light. An ultraviolet partial discharge detector can collect this ultraviolet radiation, convert it into an electrical signal using a detector, then convert it into a digital signal through a processing circuit, and finally calculate and form an image signal displayed on the display screen.

[0003] However, in practice, it has been noted that most partial discharge detectors currently have a U-shaped handle on the side. When using them, the U-shaped handle needs to be rotated to the bottom of the detector so that the screen is tilted towards the operator for easy viewing. Since the length of the handle is fixed, the tilt angle of the screen cannot be adjusted when supporting the detector. Therefore, taller people need to squat to view the screen during testing, which is tiring for long periods of time. Moreover, the tilted screen can cause blurring and inaccurate display. Utility Model Content

[0004] The purpose of this invention is to provide a partial discharge detector with a support mechanism. The handle has telescopic connecting rods at both ends, and a locking structure is provided at the connection point. This allows adjustment of the distance between the handle and the partial discharge detector, and also adjusts the tilt angle while supporting the detector, making it easier for the user to directly view the display screen. This addresses the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-8 This utility model provides a partial discharge detector with a support mechanism, including an instrument housing 1. An ultraviolet detector 4 is connected to one end of the instrument housing 1, and a carrying handle 5 is provided at the other end of the instrument housing 1. Both ends of the carrying handle 5 are movably connected to connecting rods 6, and the two ends of the carrying handle 5 are movably connected to the instrument housing 1 through the connecting rods 6.

[0029] Both ends of the carrying handle 5 are provided with storage grooves 51 that slide with the connecting rod 6, and a locking knob 7 is provided at the connection between the connecting rod 6 and the carrying handle 5. A rotary locking device 8 is installed at the end of the connecting rod 6 away from the locking knob 7, and the rotary locking device 8 is fixedly connected to both sides of the instrument housing 1.

[0030] In this embodiment, the connecting rod 6 includes an annular groove seat 61. The side of the annular groove seat 61 is integrally provided with an extension rod 62 that is inserted into the receiving groove 51. The extension rod 62 is provided with a transverse sliding groove 63, and the side of the extension rod 62 near the instrument housing 1 is provided with a rectangular array of triangular slots 64.

[0031] Furthermore, the locking knob 7 includes a threaded rotating shaft 71 that is movably connected to both ends of the carrying handle 5, and the threaded rotating shaft 71 is located inside the receiving groove 51. The end of the threaded rotating shaft 71 is integrally provided with a rotating adjustment knob located outside the carrying handle 5.

[0032] Furthermore, a rectangular slide block 72 is sleeved on the outer side of the threaded rotating shaft 71, and the threaded rotating shaft 71 and the rectangular slide block 72 are threadedly engaged, and the end of the rectangular slide block 72 is inserted into the transverse slide groove 63, and the rectangular slide block 72 is slidably connected to the transverse slide groove 63.

[0033] More specifically, the rectangular slide block 72 has a triangular locking tooth 73 integrally provided on its side, which corresponds to the triangular locking groove 64, and the triangular locking tooth 73 is engaged with the inner side of the triangular locking groove 64.

[0034] In this embodiment, the rotary locking device 8 includes mounting posts 81 fixedly connected to both sides of the instrument housing 1. The end of the mounting post 81 away from the instrument housing 1 has a threaded hole 82, and a locking bolt 85 is threadedly connected to the threaded hole 82.

[0035] Furthermore, the outer side of the mounting post 81 is interference-fitted with a rotary bearing 83, and the annular groove seat 61 has storage grooves on both sides, wherein the rotary bearing 83 is inserted into the storage groove on the side of the annular groove seat 61.

[0036] Furthermore, an end baffle 84 is placed in the storage groove on the other side. The end of the locking bolt 85 passes through the end baffle 84 and the annular groove seat 61 and is threadedly connected to the threaded hole 82. The side of the end baffle 84 fits against the annular groove seat 61.

[0037] By adopting the above technical solution, the connecting rod 6 is rotated to the bottom of the instrument housing 1 by rotating the locking device 8. The carrying handle 5 at the end of the connecting rod 6 supports the end of the instrument housing 1, so that the instrument housing 1 is tilted. The threaded rotating shaft 71 is rotated. Through the threaded engagement between the threaded rotating shaft 71 and the rectangular slide 72, the triangular locking teeth 73 are moved from one side of the triangular locking groove 64. Then, the position of the extension support rod 62 inside the storage groove 51 is adjusted, thereby adjusting the tilt angle of the instrument housing 1. After adjusting it to a suitable position, the threaded rotating shaft 71 is rotated. Through the mutual engagement of the locking teeth 73 and the triangular locking groove 64, the connection is locked.

[0038] In this embodiment, the instrument housing 1 is fixedly connected to symmetrical end supports 9 on the side near the ultraviolet detector 4. The end supports 9 support the other end of the instrument housing 1 to prevent the wires at the connection between the ultraviolet detector 4 and the instrument housing 1 from being squeezed when the instrument housing 1 is tilted.

[0039] Furthermore, an optical system is embedded at the end of the ultraviolet detector 4. The optical system focuses the ultraviolet radiation, filters it through a filter, and then irradiates the detector at the end of the optical system, whereby the detector converts it into an electrical signal.

[0040] Furthermore, a signal processing unit is installed at the other end of the detector. The electrical signal is amplified, filtered, and converted from analog to digital by the signal processing unit, converting the analog electrical signal into a digital signal, and then the digital signal is sent to the instrument housing 1 through a wire.

[0041] Furthermore, a computing circuit is installed inside the instrument housing 1. Digital signals enter the computing circuit for calculation and are converted into image signals for display on the display screen 2.

[0042] Furthermore, the bottom of the instrument housing 1 is fixedly connected with rubber seats in a rectangular array, which supports the instrument housing 1 and increases its stability when the instrument housing 1 is placed flat.

[0043] The working principle of this utility model is as follows: When using it, first hold the carrying handle 5 to carry the partial discharge detector. During use, rotate the connecting rod 6 downwards using the rotating locking device 8, so that the carrying handle 5 at the end of the connecting rod 6 rotates to the bottom of the instrument housing 1. Then tighten the locking bolt 85, and the annular groove seat 61 is fixed by the pressure of the end baffle 84. Then loosen the locking knob 7, adjust the relative position between the extension rod 62 and the storage groove 51, and adjust the tilt angle of the end of the instrument housing 1. Then rotate the threaded rotating shaft 71. Through the threaded engagement between the threaded rotating shaft 71 and the rectangular slide 72, the rectangular slide 72 drives the triangular locking teeth 73 to insert into the triangular... In slot 64, the connection between the carrying handle 5 and the connecting rod 6 is locked to ensure that the user can directly look at the display screen 2. Then, the user holds the ultraviolet detector 4 and points it toward the location of the power equipment to be detected. The optical system at the end of the ultraviolet detector 4 collects ultraviolet radiation and converts it into an electrical signal. Then, the signal processing unit amplifies, filters, and performs digital-to-analog conversion on the electrical signal. The converted digital signal is sent to the computing circuit in the instrument housing 1 through wires. After processing, it is converted into an image signal and displayed on the display screen 2. The user moves the ultraviolet detector 4 while viewing the image on the display screen 2, thereby detecting the partial discharge location of the power equipment.
