Abstract
Description
Technical Field
[0001] This application relates to the field of wind turbine positioning device technology, and in particular to a wind turbine maintenance positioning device. Background Technology
[0002] A fan is a mechanical device that converts mechanical energy into gas pressure or kinetic energy, thereby enabling gas transport, ventilation, air exchange, or power supply.
[0003] After prolonged use, fans may develop minor malfunctions, such as blade failure, motor failure, or loose internal parts causing severe shaking. When malfunctions occur, the fan needs to be disassembled for repair, and positioning devices should be used to assist in the repair process.
[0004] Existing positioning devices mainly fix the fan in place before disassembly and maintenance. However, traditional positioning devices still have certain problems in use. Completely fixing the fan in place affects the flexibility of operation during maintenance; and some parts of the fan are easily lost during disassembly and maintenance, making them difficult to find. Therefore, this application proposes a fan maintenance positioning device. Utility Model Content
[0005] The purpose of this application is to address the technical problems identified in the background section by proposing a wind turbine maintenance positioning device.
[0006] The technical solution of this application is: a wind turbine maintenance positioning device, including a support base, the upper end of which is provided with a placement groove for supporting the wind turbine body, the bottom end of which is provided with a channel, and a pair of axial positioning plates are fixedly connected to the front end of the support base, and the front end of the wind turbine body is positioned by the two axial positioning plates.
[0007] A protective frame is also fixedly connected to the front end of the support base, and the protective frame is located on the outside of the fan body.
[0008] Preferably, inclined guide plates are fixedly connected to both inner walls of the protective frame, and partitions are fixedly connected to the side of the two guide plates near the placement groove.
[0009] The two guide plates together form a parts collection cavity.
[0010] Preferably, a groove is provided on the rear side of the lower end of the support base, and a baffle is fixedly connected to the end of the channel near the groove, the baffle and the channel forming a retrieval cavity;
[0011] The depth of the retrieval cavity is made smaller than the depth of the channel to facilitate the removal of parts from the retrieval cavity.
[0012] Preferably, a push plate is slidably connected inside the part collection cavity, a push rod is fixedly connected to the side wall of the push plate, the push rod slides through the baffle, and a handle is fixedly connected to the outer end of the push rod.
[0013] Preferably, both ends of the groove are fixedly connected to a support base plate, and the bottom ends of the two support base plates are flush with the lower surface of the support base, so that the rear end of the support base is stably supported by the two support base plates.
[0014] Preferably, the upper end of the fan body protrudes above the protective frame, which facilitates the removal of the protective mesh plate of the fan body for maintenance of its internal structure.
[0015] Preferably, both axial positioning plates are arc-shaped, and when positioning the fan body, the two axial positioning plates abut against the front edge of the fan body.
[0016] Compared with the prior art, this application has the following beneficial technical effects:
[0017] This application opens a placement slot at the upper end of the support base. During maintenance, the fan body is placed in the placement slot. The two axial positioning plates on the front end face of the support base play a positioning role for the front end of the fan body, preventing the fan body from falling out of the placement slot during operation. The protective frame can also collect the disassembled protective mesh plate, and small parts fall into the parts collection cavity to prevent parts from being lost during disassembly and maintenance.
[0018] By sliding a pusher plate inside the parts collection chamber, when assembly is required after maintenance, the pusher plate is slid towards the baffle by a push rod, pushing the parts in the parts collection chamber into the retrieval chamber, thereby facilitating the retrieval of parts for assembly of the fan body.

[0029] Example
[0030] like Figures 1-4As shown, this application proposes a fan maintenance positioning device, including a support base 1. The upper end of the support base 1 has a placement groove 3 for supporting the fan body 4. The placement groove 3 is arc-shaped, increasing the support and positioning area and preventing damage to the outer wall of the fan during maintenance. The bottom end of the placement groove 3 has a channel 14. A pair of axial positioning plates 15 are fixedly connected to the front end of the support base 1. The front end of the fan body 4 is positioned by the two axial positioning plates 15, both of which are arc-shaped. When positioning the fan body 4, the two axial positioning plates 15 abut against the front edge of the fan body 4. A connecting ring is fixedly connected to the outer wall of the front end of the fan body 4. The connecting ring has several through holes. A protective mesh plate at the front end of the fan body 4 is installed on the connecting ring. The protective mesh plate also has several through holes. During installation, the through holes on the protective mesh plate are aligned with the through holes on the connecting ring, and then screws are passed through the aligned through holes and tightened with nuts. When repairing the wind turbine, first unscrew several screws in sequence to remove the protective mesh plate.
[0031] The support base 1 is also fixedly connected to a protective frame 2 at its front end. The protective frame 2 is located on the outside of the fan body 4, preventing the loss of small parts when disassembling the fan body 4. The upper end of the fan body 4 protrudes above the protective frame 2, facilitating the removal of the protective mesh plate of the fan body 4 for maintenance of its internal structure. It should be noted that inclined guide plates 5 are fixedly connected to the inner walls of both sides of the protective frame 2. A partition 13 is fixedly connected to the side of each guide plate 5 near the placement groove 3. The two guide plates 5 together form a parts collection cavity 6 for the centralized collection of disassembled parts.
[0032] Furthermore, a groove 11 is provided on the rear side of the lower end of the support base 1. Support base plates 12 are fixedly connected to both ends of the groove 11. The bottom ends of the two support base plates 12 are flush with the lower surface of the support base 1, providing stable support for the rear end of the support base 1. A baffle 10 is fixedly connected to the end of the channel 14 near the groove 11. The baffle 10 and the channel 14 form a retrieval cavity 8, making the depth of the retrieval cavity 8 less than the depth of the channel 14, facilitating the removal of parts from the retrieval cavity 8. A push plate 7 is slidably connected inside the parts collection cavity 6. A push rod 9 is fixedly connected to the side wall of the push plate 7. The push rod 9 slides through the baffle 10, and a handle is fixedly connected to the outer end of the push rod 9. The push plate 7 is relatively thin, and when disassembling the fan body 4, the push plate 7 fits tightly against the inner wall of the protective frame 2. Because the push plate 7 is very thin, even if parts fall on the upper end of the push plate 7 during disassembly, they will quickly slide into the parts collection cavity 6.
[0033] The working principle of this embodiment is as follows: When maintenance is required on the fan body 4, the protective mesh plate at the front end of the fan body 4 must first be disassembled. The fan body 4 is first placed in the placement slot 3, and then the protective mesh plate of the fan body 4 is disassembled. The disassembled screws or nuts can be directly thrown into the protective frame 2, or the parts can fall directly into the protective frame 2. After disassembly, the interior of the fan body 4 is inspected. The two axial positioning plates 15 abut against the connecting ring at the front end of the fan body 4 (the connecting ring is used to install and fix the protective mesh plate, and the protective mesh plate and the connecting ring are fixed by screws and nuts). Thus, during maintenance operations, axial sliding of the fan body 4 can be avoided, and the fan body 4 can be rotated circumferentially according to maintenance needs.
[0034] When the fan needs to be assembled after maintenance, pull the push rod 9 to move the push plate 7 toward the baffle 10. The push plate 7 will push the parts in the parts collection chamber 6 into the retrieval chamber 8, so that the workers can easily take the parts from the rear end of the support 1 to assemble the fan. In this application, when the fan is positioned and disassembled, the disassembled parts can be stored and protected to prevent the parts from being lost.
[0035] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
