Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage electroscope equipment for wind turbines, in particular to a high-voltage electroscope for wind power maintenance. Background Technique

[0002] A wind turbine is a power equipment that converts wind energy into mechanical work, the mechanical work drives the rotor to rotate, and finally outputs alternating current electricity.

[0003] A wind turbine generally consists of components such as a wind wheel, a generator, a yaw device, a tower, a speed limit safety mechanism, and an energy storage device.

[0004] When maintaining a wind turbine, a high-voltage electroscope is usually used first to check whether the generator has been powered off, and this operation is mostly manual, with relatively high risks.

[0005] In the prior art, a high-voltage electroscope generally consists of an electroscope head and a telescopic rod, and the telescopic rod is usually made of an insulating material to prevent current from conducting to the worker's body. However, when the voltage is relatively high, the insulating telescopic rod can still conduct electricity, and there is still a risk of electric shock. Content of the Utility Model

[0006] According to the deficiencies of the prior art, the purpose of the utility model is to provide a high-voltage electroscope for wind power maintenance to solve the technical problems mentioned in the above background technique.

[0007] The above technical purpose of the utility model is achieved through the following technical solutions:

[0008] A high-voltage electroscope for wind power maintenance includes an electroscope head. An insulating platform is arranged at the bottom end of the electroscope head. A connecting cylinder is arranged at one end of the insulating platform. A compression spring is arranged inside the connecting cylinder. A fusing insurance is arranged on the outer extension of the compression spring. A retracting rod is arranged on the side of the connecting cylinder away from the insulating platform. A telescopic handle is arranged at the end of the retracting rod away from the connecting cylinder.

[0009] Further, an inwardly retracting ring is arranged on the bottom side of the insulating platform, and a plugging groove matching with the inwardly retracting ring is opened on the inner wall of the connecting cylinder.

[0010] Further, the fusing insurance includes a number of connecting rings sleeved on the outer surface of the compression spring, and a fusing wire is commonly connected between two adjacent connecting rings.

[0011] Further, both the compression spring and the connecting ring are made of metal conductive materials.

[0012] Further, the retraction rod includes a sliding rod and a sliding sleeve. The sliding rod is fixedly connected to the connecting cylinder. A first magnet is arranged on the outer surface of one end of the sliding rod away from the connecting cylinder. The sliding sleeve is sleeved on the outer surface of the sliding rod, and a second magnet is arranged inside one end of the sliding sleeve close to the connecting cylinder. The second magnet attracts the first magnet.

[0013] Further, the top end of the telescopic handle is fixedly connected to the sliding sleeve, and the telescopic handle is made of insulating material.

[0014] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0015] 1. For the high-voltage electroscope for wind power maintenance, when the voltage is relatively high and the current is conducted to the connecting cylinder through the insulating platform, the heat generated by the current will fuse the fuse, release the compression spring. At this time, both ends of the compression spring will apply thrusts to both ends respectively, so that the insulating platform and the connecting cylinder are separated from each other, achieving a rapid disconnection between the electroscope and the place to be tested for electricity, preventing continuous current output, and achieving the purpose of protecting workers.

[0016] 2. For the high-voltage electroscope for wind power maintenance, when using the device, pull the sliding rod and the sliding sleeve apart so that the first magnet and the second magnet are in contact with each other to fix the position between the sliding rod and the sliding sleeve. When the compression spring expands, a thrust is applied to the sliding rod to separate the first magnet and the second magnet, and insert the sliding rod into the inside of the sliding sleeve, achieving automatic contraction of the retraction rod and rapidly moving the connecting cylinder away from the place to be tested for electricity, avoiding the risk of electric shock to workers caused by arc connection between the high-voltage end to be tested for electricity and the connecting cylinder.

[0023] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment:

[0025] Referring to Figures 1-4 , a high-voltage electroscope for wind power maintenance disclosed by the present utility model includes an electroscopic head 1, an insulating platform 2 is arranged at the bottom end of the electroscopic head 1, a connecting cylinder 3 is arranged at one end of the insulating platform 2, a compression spring 4 is arranged inside the connecting cylinder 3, a fuse 5 is arranged on the outer extension of the compression spring 4, a retracting rod 6 is arranged on the side of the connecting cylinder 3 away from the insulating platform 2, and a telescopic handle 7 is arranged at one end of the retracting rod 6 away from the connecting cylinder 3.

[0026] In this embodiment, during use, by manually holding the handle, the retracting rod 6 and the telescopic handle 7 are both stretched to the longest length, and the electroscopic head 1 is brought into contact with the position to be tested, so as to achieve the purpose of testing the wind turbine.

[0027] When there is no current at the detected location, no current passes through the electroscopic head 1 and it cannot light up.

[0028] When there is current passing through and the current is small, the current passes through the electroscopic head 1 to make it light up, and the current is blocked by the arrangement of the insulating platform 2 to prevent the current from contacting the worker.

[0029] When the voltage is large and the current is conducted from the insulating platform 2 to the connecting cylinder 3, the heat generated by the current melts the fuse 5 and releases the compression spring 4. At this time, both ends of the compression spring 4 will apply thrusts to both ends respectively, so that the insulating platform 2 and the connecting cylinder 3 are separated from each other, and the retracting rod 6 contracts rapidly, achieving the effect of quickly separating the top of the electroscope from the location to be tested and avoiding the occurrence of electric arcs, thereby achieving the purpose of protecting the worker.

[0030] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, a retracting ring 8 is arranged on the bottom side of the insulating platform 2, and an insertion slot 9 matching with the retracting ring 8 is opened on the inner wall of the connecting cylinder 3.

[0031] In this embodiment, through the provision of the adduction ring 8 and the insertion slot 9, the insulating platform 2 and the connecting cylinder 3 are inserted into each other. Then, when the compression spring 4 expands, the insulating platform 2 and the connecting cylinder 3 are separated from each other, effectively avoiding the problem that current will be conducted through the connecting cylinder 3 to the worker's body.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the fusing fuse 5 includes a plurality of connecting rings 51, and the connecting rings 51 are sleeved on the outer surface of the compression spring 4. A fusing wire 52 is commonly connected between two adjacent connecting rings 51.

[0033] In this embodiment, through the provision of the connecting ring 51, the fusing wire 52 is connected to the compression spring 4, and the compression spring 4 is pulled by the fusing wire 52, so that the compression spring 4 is in a compressed state and stores potential energy.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, both the compression spring 4 and the connecting ring 51 are made of metal conductive materials.

[0035] In this embodiment, through the provision of the compression spring 4 and the connecting ring 51 made of metal materials, current can be quickly conducted into the fusing wire 52 during use. When current passes through the fusing wire 52, the fusing wire 52 will be melted by the heat of the current. At this time, the compression spring 4 will be released, thereby achieving the purpose of separating the insulating platform 2 and the connecting cylinder 3 from each other.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-4 shown, the retraction rod 6 includes a sliding rod 61 and a sliding sleeve 62. The sliding rod 61 is fixedly connected to the connecting cylinder 3. A first magnet 63 is provided on the outer surface of the end of the sliding rod 61 away from the connecting cylinder 3. The sliding sleeve 62 is sleeved on the outer surface of the sliding rod 61, and a second magnet 64 is provided inside the end of the sliding sleeve 62 close to the connecting cylinder 3. The second magnet 64 attracts the first magnet 63.

[0037] In this embodiment, when using the device, the sliding rod 61 and the sliding sleeve 62 are pulled apart so that the first magnet 63 and the second magnet 64 are in contact with each other, achieving the purpose of fixing the position between the sliding rod 61 and the sliding sleeve 62. When the compression spring 4 expands, a thrust is applied to the connecting cylinder 3. Since the sliding rod 61 and the connecting cylinder 3 are fixedly connected, the compression spring 4 will then apply a thrust to the sliding rod 61, causing the first magnet 63 and the second magnet 64 to separate from each other, and inserting the sliding rod 61 into the interior of the sliding sleeve 62, achieving the purpose of automatically contracting the retracting rod 6. Furthermore, the connecting cylinder 3 and the energized part to be tested are rapidly moved away from each other, effectively avoiding the danger of electric shock to workers caused by arc connection between the high-voltage energized end and the connecting cylinder 3.

[0038] In a further preferred embodiment of the present invention, as Figures 1-4 shown, the top end of the telescopic handle 7 is fixedly connected to the sliding sleeve 62, and the telescopic handle 7 is made of insulating material.

[0039] In this embodiment, the safety of the device is further improved by the setting of the insulating telescopic handle 7.

[0040] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
