Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wind power generation devices, and more specifically, it relates to a charging device for backup power in a wind power pitch system. Background Technology
[0002] When the main power supply fails or fails, the backup power supply can provide the necessary power to enable the pitch system to continue to work and ensure the stable operation of the generator set. After the backup power supply releases power, it needs to be recharged using a charging cable.
[0003] However, current charging devices still have the following two shortcomings in use:
[0004] First, since wind power is mostly installed on mountaintops in the wild, these places have a lot of reptiles or rats, which can damage the charging cables.
[0005] Secondly, when workers frequently unplug or plug in the charging cable, the connection between the wire and the plug is prone to breakage. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model provides a backup power charging device for wind power pitch systems. This addresses the issues that existing wind power systems are mostly installed on mountaintops in the wild, where there are many insects or rodents that can damage the charging cables; and that the connection between the wires and the plug is prone to breakage when workers frequently unplug or plug in the charging cables.
[0007] The purpose and effect of the present invention for a backup power charging device in a wind power pitch system are achieved by the following specific technical means: the backup power charging device in a wind power pitch system includes a charging cable.
[0008] The charging cable has a plug installed at each of its left and right ends. A connecting tube is installed on the inner surface of the plug and is located on the outside of the charging cable.
[0009] The substrate has a rectangular plate structure, with two fixing plates installed at the left and right ends of the substrate. The surface of the fixing plates is provided with through holes, and baffles are uniformly installed on the upper surface of the substrate.
[0010] The pads are provided in two symmetrical sets and are fixedly installed at the middle positions of the left and right end faces of the base plate. Two transverse grooves are opened on the surface of the pads.
[0011] The device box has a door panel installed on its surface, and two locking blocks are fixedly installed on the lower end face of the device box, which are engaged in the transverse sliding groove.
[0012] Furthermore, a limiting block is installed on the surface of the baffle. The surface of the limiting block has an arc-shaped structure, and the upper end face of the limiting block has an inclined structure. The charging cable is snapped between two limiting blocks.
[0013] Furthermore, the outer end face of the connecting tube is threaded, the charging cable is sleeved with a protective sleeve, the front end of the protective sleeve is threaded, and the front end of the protective sleeve is threaded to the outside of the connecting tube.
[0014] Furthermore, rubber strips are evenly installed on the outer end face of the protective sleeve, and a cavity is opened inside the protective sleeve, with a compression spring installed inside the cavity.
[0015] Furthermore, the device box is filled with an insect repellent, and the surface of the device box is evenly provided with ventilation holes.
[0016] Furthermore, an iron strip is installed on the surface of the transverse slide groove, and a magnet is installed on the lower end face of the locking block. When the locking block is engaged inside the transverse slide groove, the magnet and the iron strip are in contact.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] In this invention, a connecting tube is installed on the surface of the plug, and the outside of the connecting tube is threaded. The front end of the protective sleeve is threaded to the outside of the connecting tube. In this way, the protective sleeve can protect the connection between the charging cable and the plug, so that when the worker pulls out or inserts the plug, the connection between the charging cable and the plug can be prevented from breaking.
[0019] In addition, baffles are evenly installed on the upper surface of the substrate, and limit blocks are installed on the surface of the baffles. When the charging cable is relatively long, the charging cable can be clamped between two adjacent baffles. At this time, the charging cable is in contact with the limit block on the surface of the baffle. The inner end face of the limit block has an arc structure, which can increase the contact area between the limit block and the charging cable.
[0020] In addition, the device box is filled with insect repellent, and the surface of the device box has ventilation holes. The smell of the medicine will be released outward through the ventilation holes to prevent crawling insects or rats from damaging the charging cable. The locking block at the bottom of the device box is engaged in the horizontal sliding groove on the surface of the pad. At this time, the iron strip on the surface of the horizontal sliding groove is in contact with the magnet at the bottom of the locking block. Through the attraction between the magnet and the iron strip, the device box can be fixed to the upper surface of the pad. Attached Figure Description

The surface of the limiting block 4011 is an arc-shaped structure, and the upper end face of the limiting block 4011 is inclined. The charging cable 1 is snapped between the two limiting blocks 4011, which makes it easy for the worker to insert the charging cable 1 between the two limiting blocks 4011.
[0038] The outer end face of the connecting tube 1011 is threaded, and the charging cable 1 is sleeved with a protective sleeve 2. The front end of the protective sleeve 2 is threaded, and the front end of the protective sleeve 2 is threaded to the outside of the connecting tube 1011. The protective sleeve 2 can protect the connection between the charging cable 1 and the plug 101.
[0039] Among them, rubber strips 201 are evenly installed on the outer end face of the protective sleeve 2, and a cavity 202 is opened inside the protective sleeve 2. A compression spring 3 is installed inside the cavity 202, which can improve the toughness of the protective sleeve 2.
[0040] The device box 6 is filled with insect repellent, and the surface of the device box 6 is evenly provided with ventilation holes 601. The insect repellent can be released outward through the ventilation holes 601, which can prevent the charging cable 1 from being damaged by crawling insects.
[0041] Among them, an iron strip 5011 is installed on the surface of the transverse slide 501, and a magnet 701 is installed on the lower end face of the locking block 7.
