Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of variable pitch slip rings, in particular to a variable pitch slip ring which is easy to maintain. Background Art
[0002] The pitch slip ring is a signal transmission and deceleration device, mainly used in the field of wind power. It transmits electrical power and signals through a rotating interface to ensure that the wind turbine can effectively adjust the blades during operation to adapt to different wind speed conditions, thereby enhancing power generation capacity and ensuring signal stability.
[0003] However, the following problems still exist during the operation: when a pitch slip ring fails and needs to be investigated and regularly maintained, its structural problems are very complicated to handle, so when a failure occurs at the work site, the manufacturer has to return to the slip ring for troubleshooting and repair, which results in a long time spent on overall troubleshooting and repair, and also leads to transportation costs. For this reason, the utility model provides a pitch slip ring that is easy to maintain. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a variable pitch slip ring that is easy to maintain, and has the advantages of being able to timely and efficiently troubleshoot the inside of the slip ring, facilitating observation of the inside of the slip ring, and performing simple maintenance work. It solves the problem raised in the background technology that when a variable pitch slip ring has a fault and needs to be troubleshooted and undergoes regular basic maintenance, its structural problems are very complicated to handle, resulting in the need to return to the slip ring manufacturer for troubleshooting and repair when a fault occurs at the work site, which results in a long time spent on overall troubleshooting and repair, and also leads to the generation of transportation costs.
[0005] The utility model provides the following technical solution: a variable pitch slip ring which is easy to maintain, comprising a front end cover, a middle end cover, a rear end cover, a box frame, a box cover plate and a side end cover, wherein the left side of the box frame is connected to the front end cover by screws, the right side of the front end cover is connected to the rear end cover by screws, the top and bottom of the front end cover are respectively connected to the box cover plate by screws, and the front and back sides of the front end cover are connected to the side end covers by screws.
[0006] Preferably, the interior of the front end cover is connected to a middle end cover via screws.
[0007] Preferably, sealing gaskets are respectively provided on the top and bottom of the box frame.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] The variable pitch slip ring is easy to maintain, the operator connects the front end cover, the middle end cover and the rear end cover together through the box frame with screws, and then connects and fastens the box frame with the box cover plate by screws. When the box frame and the box cover plate are assembled, the sealing treatment is performed with a sealing gasket to complete the assembly, and the reverse operation is required for disassembly. It effectively solves the limitation problem that when the variable pitch slip ring fails and needs to be troubleshooted and regular basic maintenance is performed, the structural problem is very complicated to handle, resulting in the need to return to the slip ring manufacturer for troubleshooting and repair when a failure occurs at the work site. It solves the problem that when the variable pitch slip ring fails during use, the internal fault of the slip ring can be timely and efficiently troubleshooted, and the variable pitch slip ring is convenient for observation of the internal part of the slip ring during regular basic maintenance, as well as simple maintenance work. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the overall structure of the utility model device.
[0011] In the figure: 1, front end cover; 2, middle end cover; 3, rear end cover; 4, box frame; 5, box cover plate; 6, side end cover. DETAILED DESCRIPTION
[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] See also Figure 1 , a variable pitch slip ring that is easy to maintain, includes a front end cover 1, an intermediate end cover 2, a rear end cover 3, a box frame 4, a box cover plate 5 and a side end cover 6. The left side of the box frame 4 is connected with the front end cover 1 by screws, and the right side of the front end cover 1 is connected with the rear end cover 3 by screws. The top and bottom of the front end cover 1 are respectively connected with the box cover plate 5 by screws, the front and back of the front end cover 1 are connected with the side end cover 6 by screws, and the interior of the front end cover 1 is connected with the intermediate end cover 2 by screws. The top and bottom of the box frame 4 are respectively provided with sealing gaskets. The operator fastens the front end cover 1, the intermediate end cover 2 and the rear end cover 3 together through the box frame 4 with screws, and then fastens them with the box cover plate 5 with screws to the box frame 4. When the box frame 4 and the box cover plate 5 are assembled, the sealing treatment is performed with the sealing gasket, and the assembly is completed. When disassembling, the reverse operation can be performed. When the variable pitch slip ring fails during use, the internal fault of the slip ring can be timely and efficiently troubleshooted, and the variable pitch slip ring is convenient for observation of the internal part of the slip ring during regular basic maintenance, as well as simple maintenance work.
[0014] Working principle: During the operation, the operator fastens the front end cover 1, the middle end cover 2 and the rear end cover 3 together through the box frame 4 with screws, and then fastens the box cover plate 5 to the box frame 4 with screws. When the box frame 4 and the box cover plate 5 are assembled, they are sealed with a sealing gasket and the assembly is completed. When disassembling, just perform the reverse operation.
