Description

Technical Field

[0001] This utility model relates to the field of wind power generation, specifically a braking component for micro wind turbine generator sets. Background Technology

[0002] A wind turbine is a generator that uses a wind turbine to rotate under the influence of wind. It converts the kinetic energy of the wind into the mechanical energy of the turbine shaft, which in turn drives the generator to rotate and generate electricity. In a broader sense, wind energy is also solar energy, so a wind turbine can also be described as a generator that uses the sun as a heat source and the atmosphere as a medium to utilize thermal energy.

[0003] The braking components of current micro wind turbine generator sets, as described in patent CN215257498U, include: a wind turbine shaft, a gearbox, and a motor. The wind turbine shaft is fixedly connected to the gearbox, and the gears of the gearbox are fixedly connected to the motor shaft. A brake disc is fixedly mounted on the motor shaft, and a buffer spring is mounted on the brake disc. The buffer spring is semi-circular and fixedly mounted in an annular mounting groove on the brake disc. A limiting disc is movably connected to the annular mounting groove, and the limiting disc is fixedly connected to the buffer spring. A hydraulic rod is fixedly mounted at the front end of the motor, and a tray is mounted on one end of the hydraulic rod. The tray has several grooves that are evenly distributed in a circular pattern. Each groove has a friction pad on its edge, and one end of the friction pad is hinged to the inside of the groove.

[0004] Regarding the aforementioned technologies, the inventors believe that as the entire braking device is used for a long time, when the brake pads and friction pads wear out and need to be replaced, the brake pads and friction pads need to be disassembled. Since both the brake pads and friction pads are circular, they need to be removed from one end of the motor shaft during disassembly. Therefore, it is necessary to disassemble and separate the connection between the motor shaft and the impeller shaft, which makes the disassembly and assembly of the brake pads and friction pads inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a braking component for micro wind turbine generator sets to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A braking assembly for a micro wind turbine generator set, comprising

[0008] The following mechanism includes a speed-increasing gearbox. The input shaft of the speed-increasing gearbox is symmetrically fitted with inner retaining plates. A set of inner retaining plates has a spline groove inside. The spline groove has a spline fixedly connected to the speed-increasing gearbox. Multiple inner brake plates are evenly fixedly connected to the outer sides of the two sets of inner retaining plates.

[0009] The braking mechanism includes a fixed plate fixedly connected to one side of the speed-increasing gearbox. The fixed plate is symmetrically fixedly connected to a first hydraulic rod. The output ends of the two sets of first hydraulic rods are fixedly connected to a traction block by bolts. One side of each set of traction blocks is fixedly connected to an outer bearing plate. Multiple outer brake plates are evenly fixedly connected to the inner walls of the two sets of outer bearing plates. Each set of outer brake plates is respectively disposed between two adjacent inner brake plates.

[0010] The limiting mechanism includes a support frame disposed on one side of the speed-increasing gearbox. A second hydraulic rod is symmetrically fixed through the inside of the support frame. The output ends of the two sets of second hydraulic rods are fixedly connected to clamping plates. Limiting blocks are symmetrically fixedly connected to both sides of the two sets of clamping plates. A ball bearing is movably connected to the side of each set of limiting blocks near the inner clamping plate. Ball bearing grooves adapted to the ball bearings are symmetrically opened on the outer sides of the two sets of inner clamping plates.

[0011] As a further embodiment of this utility model: the inner brake plate of each group and the outer brake plate of each group are both semi-disc-shaped structures.

[0012] As a further embodiment of this utility model: one side of each group of inner brake plates is fixedly connected with a plurality of first reinforcing ribs in a circular array, and each group of first reinforcing ribs is fixedly connected to the inner retaining tile; one side of each group of outer brake plates is fixedly connected with a third reinforcing rib in a circular array, and each group of third reinforcing ribs is fixedly connected to the outer retaining tile.

[0013] As a further embodiment of this utility model: a plurality of second reinforcing ribs are fixedly connected in a ring array on one side of the fixing plate, and each group of second reinforcing ribs is fixedly connected to the speed-increasing gearbox.

[0014] As a further embodiment of this utility model: guide posts are fixedly connected to one side of both sets of traction blocks, and both sets of guide posts slide through the fixed plate.

[0015] As a further embodiment of this utility model: one side of each of the two sets of clamping tiles is provided with a clearance groove, and the two sets of clearance grooves correspond to the two sets of traction blocks respectively.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] With the above-described structure, this invention utilizes the cooperation of the inner brake plate, outer brake plate, second hydraulic rod, and clamping shoes. The output end of the first hydraulic rod is connected and fixed to the traction block via bolts. When the inner and outer brake plates are severely worn and require replacement, the bolts connecting the first hydraulic rod to the traction block can be removed first. Then, the two sets of second hydraulic rods are activated, causing the two sets of clamping shoes and the side limit blocks to move in opposite directions. This causes the balls to move out of the ball grooves, releasing the restriction on the inner clamping shoe. The inner and outer clamping shoes can then be removed, thus achieving the disassembly of both. This eliminates the need to disassemble the input shaft of the speed-increasing gearbox from the wind turbine shaft when disassembling the inner and outer brake plates, making the replacement of the inner and outer brake plates more convenient.

Detailed Implementation

[0024] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0025] Please see Figure 1-4A braking assembly for a micro wind turbine generator set includes a follower mechanism 1. The follower mechanism 1 includes a speed-increasing gearbox 101. Inner retaining plates 103 are symmetrically fitted on the outer side of the input shaft of the speed-increasing gearbox 101. A set of inner retaining plates 103 has a spline groove 104 inside. The spline groove 104 contains a spline 102 fixedly connected to the speed-increasing gearbox 101. The spline groove 104 accommodates the spline 102, allowing the spline 102 and the inner retaining plates 103 to rotate when the input shaft of the speed-increasing gearbox 101 rotates. Multiple inner brake plates 105 are evenly fixedly connected to the outer sides of the two sets of inner retaining plates 103. The inner brake plates 105 rotate synchronously with the rotation of the inner retaining plates 103.

[0026] Each set of inner brake plates 105 has multiple first reinforcing ribs 106 fixedly connected in a circular array on one side. Each set of first reinforcing ribs 106 is fixedly connected to the inner retaining plate 103. The first reinforcing ribs 106 are used to further connect and fix the inner brake plate 105 and the inner retaining plate 103, thereby improving the connection stability between the inner brake plate 105 and the inner retaining plate 103. The limiting mechanism 3 includes a support frame 306 disposed on one side of the speed-increasing gearbox 101. Second hydraulic rods 305 are symmetrically fixed through the inside of the support frame 306. The support frame 306 is used to support the second hydraulic rods 305. The output ends of the two sets of second hydraulic rods 305 are fixedly connected to clamping plates 301. The second hydraulic rods 305 can drive the clamping plates 301 to move during start-up.

[0027] Two sets of clamping tiles 301 are symmetrically fixedly connected to both sides of limiting blocks 302. Each set of limiting blocks 302 has a ball bearing 304 movably connected to the side of the inner clamping tile 103. The outer sides of the two sets of inner clamping tiles 103 are symmetrically provided with ball bearing grooves 303 adapted to the ball bearings 304. The limiting blocks 302 and the ball bearings 304 can move synchronously with the clamping tiles 301, so that the ball bearings 304 can limit the inner clamping tile 103 after moving into the ball bearing groove 303. Braking mechanism 2 includes a fixing plate 201 fixedly connected to one side of speed-increasing gearbox 101. One side of the fixing plate 201 is fixedly connected with multiple second reinforcing ribs 207 in a circular array. Each set of second reinforcing ribs 207 is fixedly connected to the speed-increasing gearbox 101. The setting of the second reinforcing ribs 207 is used to further connect and fix the fixing plate 201 and the speed-increasing gearbox 101, thereby improving the connection stability between the fixing plate 201 and the speed-increasing gearbox 101.

[0028] The fixed plate 201 is symmetrically fixed with first hydraulic rods 202. The output ends of the two sets of first hydraulic rods 202 are fixedly connected to traction blocks 203 by bolts. The use of bolts to connect and fix the first hydraulic rods 202 to the traction blocks 203 facilitates the subsequent disassembly of the traction blocks 203. Guide posts 206 are fixedly connected to one side of each of the two sets of traction blocks 203. Both sets of guide posts 206 slide through the fixed plate 201, and the guide posts 206 guide the movement of the traction blocks 203. Alternating grooves 205 are provided on one side of each of the two sets of clamping plates 301. The two sets of alternating grooves 205 correspond to the two sets of traction blocks 203, and the alternating grooves 205 allow for the movement of the traction blocks 203 to be avoided.

[0029] Both sets of traction blocks 203 have outer retaining tiles 204 fixedly connected to one side, and the outer retaining tiles 204 can move synchronously with the traction blocks 203. Multiple outer brake plates 209 are uniformly fixedly connected to the inner walls of both sets of outer retaining tiles 204. Each set of outer brake plates 209 has a third reinforcing rib 208 fixedly connected to one side in a circular array. Each set of third reinforcing ribs 208 is fixedly connected to the outer retaining tiles 204. The third reinforcing ribs 208 are used to further connect and fix the outer retaining tiles 204 to the outer brake plates 209, thereby improving the connection stability between the outer retaining tiles 204 and the outer brake plates 209.

[0030] Each set of outer brake plates 209 is respectively disposed between two adjacent inner brake plates 105. The outer brake plates 209 are disposed so that they can move synchronously with the outer bearing plates 204. When the outer bearing plates 204 move to contact the outer brake plates 209, the friction between the outer brake plates 209 and the inner brake plates 105 is used to brake the inner brake plates 105 and the speed-increasing gearbox 101. Each set of inner brake plates 105 and each set of outer brake plates 209 are semi-disc-shaped. The semi-disc-shaped inner brake plates 105 and semi-disc-shaped outer brake plates 209 can effectively increase the contact area between the outer brake plates 209 and the inner brake plates 105, thereby improving the braking effect.

[0031] In this embodiment, the speed-increasing gearbox 101 is prior art and will not be described in detail here.

[0032] In use, when braking of the input shaft of the speed-increasing gearbox 101 is required, the two sets of first hydraulic rods 202 can be activated. This causes the first hydraulic rods 202 to move the traction block 203 and the outer retaining plate 204 away from the speed-increasing gearbox 101. As the outer retaining plate 204 moves away from the speed-increasing gearbox 101, it drives each set of outer brake plates 209 to move towards the inner brake plate 105. This causes each set of outer brake plates 209 to rub against each set of inner brake plates 105, thereby restricting the movement of the inner brake plates 105 and the two sets of... The inner brake plate 103 rotates, thereby braking the input shaft of the speed-increasing gearbox 101. When the inner brake plate 105 and outer brake plate 209 are severely worn and need to be replaced, a wrench can be used to unscrew the bolts connecting the traction block 203 and the output end of the first hydraulic rod 202, thus separating the traction block 203 from the first hydraulic rod 202. Then, the two sets of second hydraulic rods 305 are activated, thereby driving the two sets of clamping plates 301 and the two side limit blocks 302 to move in opposite directions, causing each set of balls 304 to move out of the ball groove 303, thus releasing the brakes. After limiting the inner retaining plate 103, the inner retaining plate 103 and the outer retaining plate 204 can be removed, thereby disassembling the outer retaining plate 204 and the inner retaining plate 103. Then, new inner retaining plates 103 and outer retaining plates 204 are taken out, and the sets of inner brake plates 105 on the new inner retaining plates 103 are inserted between two adjacent outer brake plates 209 on the new outer retaining plates 204. Then, the two sets of new inner retaining plates 103 are fitted onto the outside of the input shaft of the speed-increasing gearbox 101, and the inner side of the new inner retaining plates 103 is closed. The spline 102 is aligned with the spline groove 104. Then, the two sets of second hydraulic rods 305 are activated, causing the two sets of second hydraulic rods 305 to drive the two side limit blocks 302 to move inward to hold the tile 103 until each set of ball bearings 304 moves with each set of limit blocks 302 to abut against the inner wall of the ball bearing groove 303, thereby achieving the limit installation of the two sets of inner tile bearings 103. Afterward, the output ends of the two sets of first hydraulic rods 202 are connected and fixed to the two sets of traction blocks 203 respectively using bolts, thereby completing the replacement of the inner brake plate 105 and the outer brake plate 209.

[0033] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
