Description

Technical Field

[0001] This utility model belongs to the field of unit monitoring technology, specifically a wind turbine capacitor monitoring device. Background Technology

[0002] In capacitance and inductance testing, the capacitor is connected to the terminals of the tester via a wiring harness. The connection between the wiring harness and the capacitor terminals is mostly a scissor-type conductive clip structure. Common capacitor terminals are raised columnar structures. However, the scissor-type clip lacks a positioning mechanism and relies solely on the friction between the clamping force and the terminal to achieve the clamping connection. However, due to the unreliable elastic clamping, the shaking of the wiring harness during testing can easily cause the scissor-type clip to gradually slip off and eventually detach from the terminal, causing great inconvenience to the actual testing work. Therefore, it is necessary to develop a wind turbine capacitor monitoring device to solve the shortcomings of the existing technology. Utility Model Content

[0003] To address the problems mentioned in the background section, this invention provides a wind turbine capacitor monitoring device, which has the advantages of stable connection and high security.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wind turbine capacitor monitoring device, comprising a protective shell, wherein a detector body is fixedly embedded inside the protective shell, and a cover-type storage box is hinged to the protective shell, wherein a storage component is movably embedded inside the cover-type storage box, and a connecting component is clamped inside the storage component, wherein the connecting component is encapsulated in the cover-type storage box by the storage component.

[0005] The connection assembly includes a connection harness connecting the detector body and the capacitor. One end of the connection harness is fixedly connected to an aviation plug, and the other end of the connection harness is fixedly connected to two symmetrical conductive clamping heads. The two conductive clamping heads have a scissor-type clamping handle integrally formed on the outside of the connection harness near one end of the connection harness. One of the scissor-type clamping handles has a plurality of evenly distributed positioning grooves on the outer surface of the other scissor-type clamping handle. A positioning component is movably connected to the other scissor-type clamping handle, and the other end of the positioning component abuts against the inside of the positioning groove.

[0006] Preferably, the aviation plug is inserted into the detector body, and the conductive clamping head is clamped onto the capacitor terminal of the wind turbine.

[0007] Preferably, the two scissor grips are connected by a spring at one end near the conductive gripping head, and conductive plates are embedded in the opposing surfaces of the two conductive gripping heads. The conductive plates are in contact with the capacitor terminals and are fixedly connected to the connecting wire harness.

[0008] Preferably, the positioning component includes a linkage plate disposed on the upper and lower exterior of the scissor grip, a positioning shaft is fixedly connected to one end of the linkage plate, a limiting shaft is fixedly connected to the other end of the linkage plate, the positioning shaft is movably engaged inside the positioning groove, and the limiting shaft is movably sleeved inside the scissor grip.

[0009] Preferably, the linkage plate is provided with two positioning rings, one upper and one lower, which are sleeved on the outside of the limiting shaft. The two positioning rings are respectively fixedly connected to the upper and lower sides of the outer surface of the scissor grip.

[0010] Preferably, a spring is provided inside the positioning ring, one end of which is fixedly connected to the outer surface of the limiting shaft, and the other end of which is fixedly connected to the inner wall of the limiting shaft.

[0011] Preferably, the storage component includes two front and rear limiting rings that are movably embedded inside the lid-type storage box and interlock with each other. An elastic limiting block is fixedly sleeved inside each of the two limiting rings. The distance between the back sides of the two limiting rings is smaller than the distance between the front and rear sides of the lid-type storage box. Two symmetrical elastic connecting strips are provided on the outer surface of the two limiting rings. The two ends of the elastic connecting strips are fixedly connected to the two limiting rings respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. Due to the positioning component, the two ends of the positioning component can be held between the two scissor grips with the cooperation of the positioning groove. This ensures that the distance between the two scissor grips is maintained after the upper elastic restoring force of the two conductive clamping heads tightens the capacitor terminals. This effectively reduces the situation where the conductive clamping heads slowly slip off the capacitor terminals due to unstable elastic factors during clamping, thereby ensuring connection stability.

[0014] 2. Due to the design of the storage component, this utility model, with the cooperation of the limiting ring, makes it easy for workers to store the connecting wire harness and its conductive clamps and aviation plugs at both ends between the two elastic limiting blocks. Moreover, with the cooperation of the elastic connecting strip, it is ensured that the two elastic limiting blocks can firmly clamp the stored connecting component, so that it can be embedded into the inside of the lid-type storage box, and it is also easy to retrieve, effectively improving the storage efficiency.

[0015] 3. Due to the setting of the elastic limiting block, the present invention can facilitate the staff to store the connecting component inside the lid-type storage box with the cooperation of the limiting ring and the elastic connecting strip. It can also separate the connecting component from the detector body, so as to avoid the connecting component sliding on the surface of the detector body during the movement after storage, which would cause wear on the surface of the detector body.

[0022] 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.

[0023] like Figures 1 to 5 As shown, this utility model provides a wind turbine capacitor monitoring device, including a protective shell 1, a detector body 2 fixedly embedded inside the protective shell 1, a cover-type storage box 4 hinged to the protective shell 1, a storage component 5 movably embedded inside the cover-type storage box 4, a connecting component 3 clamped inside the storage component 5, and the connecting component 3 is encapsulated in the cover-type storage box 4 by the storage component 5.

[0024] The connection assembly 3 includes a connection harness 31 connecting the detector body 2 and the capacitor. One end of the connection harness 31 is fixedly connected to an aviation plug 36, and the other end of the connection harness 31 is fixedly connected to two symmetrical conductive clamping heads 35. A scissor-type clamping handle 32 is integrally formed on the end of the two conductive clamping heads 35 near the connection harness 31 and is sleeved on the outside of the connection harness 31. One of the scissor-type clamping handles 32 has a plurality of evenly distributed positioning grooves 34 on its outer surface near the other scissor-type clamping handle 32. The device is connected to a positioning component 33, with one end of the positioning component 33 abutting against the inside of the positioning groove 34. Due to the positioning component 33, with the cooperation of the positioning groove 34, both ends of the positioning component 33 can abut against the two scissor grips 32, ensuring that the distance between the two scissor grips 32 is fixed after the upper elastic restoring force of the two conductive clamping heads 35 clamps the capacitor terminals. This effectively reduces the possibility of the conductive clamping heads 35 slowly slipping off the capacitor terminals due to unstable elastic factors during clamping, thereby ensuring connection stability.

[0025] like Figure 1 As shown, the aviation plug 36 is plugged into the detector body 2, and the conductive clamping head 35 is clamped onto the capacitor terminal of the wind turbine.

[0026] like Figure 4 As shown, the two scissor grips 32 are connected by a spring at one end near the conductive gripping head 35. The opposing surfaces of the two conductive gripping heads 35 are each embedded with a conductive sheet. The conductive sheet contacts the capacitor terminal and is fixedly connected to the connecting wire harness 31.

[0027] like Figure 4 and Figure 5 As shown, the positioning component 33 includes a linkage plate 331 disposed on the upper and lower exterior of the scissor grip 32. One end of the linkage plate 331 is fixedly connected to a positioning shaft 332, and the other end of the linkage plate 331 is fixedly connected to a limiting shaft 334. The positioning shaft 332 is movably engaged in the interior of the positioning groove 34, and the limiting shaft 334 is movably sleeved in the interior of the scissor grip 32.

[0028] like Figure 5 As shown, the linkage plate 331 has two positioning rings 333 inside, which are sleeved on the outside of the limiting shaft 334. The two positioning rings 333 are fixedly connected to the upper and lower sides of the outer surface of the scissor grip 32 respectively. Due to the setting of the positioning rings 333, the spring spring 335 can be encapsulated to reduce the corrosion of the spring spring 335 by moisture and dirt in the air. At the same time, it can restrict the movement of the outer end of the spring spring 335, so that the elastic strength of the spring spring 335 can be increased when the linkage plate 331 drives the limiting shaft 334 to rotate.

[0029] like Figure 5As shown, a spring 335 is provided inside the positioning ring 333. One end of the spring 335 is fixedly connected to the outer surface of the limiting shaft 334, and the other end of the spring 335 is fixedly connected to the inner wall of the limiting shaft 334. Due to the elastic restoring force of the spring 335, the linkage plate 331 can swing in the opposite direction, thereby causing the positioning shaft 332 at the other end of the linkage plate 331 to abut against the inside of the positioning groove 34, thus ensuring that the distance between the two scissor grips 32 remains fixed.

[0030] like Figure 2 and Figure 3 As shown, the storage component 5 includes two front and rear limiting rings 51 that are movably embedded inside the lid-type storage box 4 and interlock with each other. An elastic limiting block 52 is fixedly sleeved inside each of the two limiting rings 51. The distance between the back sides of the two limiting rings 51 is smaller than the distance between the front and rear sides of the lid-type storage box 4. Two symmetrical elastic connecting straps 53 are provided on the outer surface of the two limiting rings 51, with both ends of the elastic connecting straps 53 fixedly connected to the two limiting rings 51. Due to the design of the storage component 5, with the cooperation of the limiting rings 51, it is convenient for workers to store the connecting wire harness 31 and its conductive clamps 35 and aviation plug 36 as a whole within the two limiting rings 51. Between the two elastic limiting blocks 52, and with the cooperation of the elastic connecting strip 53, it is ensured that the two elastic limiting blocks 52 can firmly clamp the storage connecting component 3, so that it can be embedded into the inside of the lid-type storage box 4, and it is also easy to retrieve, effectively improving the storage efficiency. Due to the setting of the elastic limiting block 52, with the cooperation of the limiting ring 51 and the elastic connecting strip 53, it is easy for the staff to store the connecting component 3 into the inside of the lid-type storage box 4, and it can separate the connecting component 3 from the detector body 2, so as to avoid the connecting component 3 sliding on the surface of the detector body 2 during movement after storage, causing wear on the surface of the detector body 2.

[0031] Working principle and usage process of this utility model:

[0032] After opening the lid-type storage box 4 and taking out the storage component 5, pull the two limiting rings 51 to make the two elastic limiting blocks 52 move away from each other, so as to take out the connecting component 3 that is clamped and stored between them. Then, plug the aviation plug 36 at one end of the connecting wire harness 31 into the detector body 2, and clamp the conductive clamping head 35 onto the wind turbine capacitor terminal.

[0033] The specific operation is as follows: Hold both scissor-clip handles 32 firmly with one hand, while hooking the linkage plate 331 with your ring finger. Under the constraint of the limiting shaft 334, the other end of the linkage plate 331 will move the positioning shaft 332 to disengage from the positioning groove 34. Then, further tighten the two scissor-clip handles 32 to bring them closer together, thus moving the two conductive gripping heads 35 at the front end away from each other. At this point, connect the two conductive gripping heads 35 to the capacitor terminals and slowly release the gripping force. This will connect the two scissor-clip handles 32. Under the restoring force of the spring at the end, the two scissor grips 32 move away from each other, while the two conductive clamping heads 35 clamp the capacitor terminals; then, the ring finger releases the linkage plate 331, and under the elastic restoring force of the spring 335, the upper and lower linkage plates 331 swing in opposite directions through the limiting shaft 334, and drive the positioning shaft 332 at the other end to engage in the positioning groove 34, so as to prevent the two scissor grips 32 from getting close to each other, so that the two conductive clamping heads 35 are firmly clamped on the capacitor terminals.
