[0002] Vertical axis wind power generation refers to the technology of converting wind energy into electrical energy using vertical axis wind turbines. The main feature of vertical axis wind turbines is that their rotation axis is perpendicular to the ground or the direction of airflow, in sharp contrast to horizontal axis wind turbines whose rotation axis is parallel to the wind direction.

[0003] Prior art, such as publication number CN216198656U, discloses a wind turbine generator protective device comprising a protective housing, an inner cavity of the protective housing housing housing a power generation assembly, a rotating hub disposed on one side of the protective housing, a fixed ring fixedly coupled to the outer wall of the rotating hub, a rainproof ring fixedly coupled to one side of the fixed ring, an annular inclined groove defined in the inner wall of the rainproof ring, a first water-blocking ring fixedly coupled to the outer wall of the protective housing, a second water-blocking ring fixedly coupled to the outer wall of the protective housing at a position to one side of the first water-blocking ring, an annular limiting groove defined in the inner wall of the annular inclined groove, the annular limiting groove being rotatably connected to the outer wall of the second water-blocking ring, and drainage grooves symmetrically defined in the outer wall of the protective housing. The present invention utilizes the rainproof ring, the first water-blocking ring, and the second water-blocking ring to prevent rainwater from flowing between the protective housing and the rotating hub, thereby improving the rainproofness of the protective housing.

[0004] In order to solve the problem of existing equipment protecting the engine unit, since most of the existing engine units have heat dissipation holes on the surface, when thunderstorms occur, the engine unit is eroded by rain for a long time, and the rain will enter the interior of the engine unit, causing corrosion damage to equipment parts. Improvements are needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that most of the existing engine units in the prior art have heat dissipation holes on the surface. When thunderstorms occur, the engine units are eroded by rain for a long time, and rainwater enters the interior of the engine units, causing corrosion and damage to equipment parts. A vertical axis wind power transmission system is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a transmission system for vertical axis wind power generation, including a pole, a base, an engine group, blades and a protective device, the base is fixedly connected to the lower surface of the pole, the engine group is arranged above the pole, the blades are arranged on the surface of the pole, the engine group is provided with a heat dissipation groove, the surface of the engine group is provided with a protective device, the protective device includes a protective cover, the upper surface of the engine group is rotatably connected to a stud, the surface of the stud is provided with a sleeve column, and the protective cover is fixedly connected to the upper surface of the sleeve column.

[0007] Furthermore, a thread groove is provided on the surface of the sleeve, and the stud is threadedly driven with the inner wall of the thread groove.

[0008] Furthermore, the upper surface of the engine group is fixedly connected with guide rods, the number of the guide rods is two and they are symmetrically arranged, and the upper surface of the guide rods away from the engine group is fixedly connected with anti-slip blocks.

[0009] Furthermore, a connection block is fixedly connected to the surface of the sleeve column, the connection blocks are in two groups and are symmetrically arranged, and the connection blocks are slidably connected to the surface of the guide rod.

[0010] Furthermore, a fixing bar is fixedly connected to the surface of the guide rod, and the fixing bar is sleeved and connected to the surface of the stud. The upper surface of the engine group is fixedly connected to a bracket, and the surface of the bracket is fixedly connected to the rotating motor.

[0011] Furthermore, the driving end of the rotating motor is rotatably connected to a rotating shaft, and the surface of the rotating shaft is fixedly connected to a first gear.

[0012] Furthermore, a second gear is fixedly connected to the surface of the stud, the second gear is arranged below the fixing bar, and the second gear is gear-driven with the inner wall of the first gear.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, by providing a protective device, the use of the protective cover is more convenient when protecting the engine unit. The rotating motor drives the rotating shaft to rotate, thereby causing the first gear and the second gear to transmit, and then drives the stud to rotate, so that the stud and the inner side of the sleeve are transmitted, so that the sleeve is adjusted to rise and fall in the vertical direction along the surface of the guide rod. When the weather is clear, the protective cover can be raised to the top, so that the heat dissipation groove can dissipate heat and ventilation for the engine unit, and the protective cover can shade the engine unit.

[0015] 2. In the present invention, when encountering thunderstorm weather, the sleeve column drives the protective cover to move downward, and when the stud drives the sleeve column to move downward, the sleeve column surface collides with the fixing bar, thereby preventing the sleeve column from moving downward too much and colliding with the second gear surface to cause damage. At the same time, it also drives the protective cover to cover the heat dissipation groove, thereby preventing rainwater from penetrating into the inner wall of the engine unit through the heat dissipation groove. By setting up the protective device, it is convenient to protect the engine unit, thereby avoiding the situation that most of the existing engine units have heat dissipation holes on the surface. When thunderstorm weather occurs, the engine unit is eroded by rainwater for a long time, and the rainwater will enter the interior of the engine unit, causing corrosion damage to equipment parts, thereby effectively improving the safety of the equipment.

[0023] See also Figure 1-Figure 5 The present invention provides a technical solution: a transmission system for vertical axis wind power generation, including a pole 1, a base 2, an engine group 3, blades 4 and a protective device 5, the base 2 is fixedly connected to the lower surface of the pole 1, the engine group 3 is arranged above the pole 1, the blades 4 are arranged on the surface of the pole 1, the engine group 3 is provided with a heat dissipation groove 51, and the surface of the engine group 3 is provided with a protective device 5.

[0024] The specific configuration and function of the protective device 5 will be described in detail below.

[0025] In this embodiment, the protective device 5 includes a protective cover 54 , a stud 52 is rotatably connected to the upper surface of the engine block 3 , a sleeve 53 is provided on the surface of the stud 52 , and the protective cover 54 is fixedly connected to the upper surface of the sleeve 53 .

[0026] Specifically, a thread groove 55 is formed on the surface of the sleeve 53 , and the stud 52 is threadedly coupled to the inner wall of the thread groove 55 .

[0027] Specifically, the upper surface of the engine block 3 is fixedly connected with guide rods 56 , and there are two groups of guide rods 56 symmetrically arranged. The upper surface of the guide rods 56 away from the engine block 3 is fixedly connected with an anti-slip block 57 .

[0028] Specifically, the surface of the sleeve column 53 is fixedly connected with a connecting block 58 . The connecting blocks 58 are in two groups and are symmetrically arranged. The connecting blocks 58 are slidably connected to the surface of the guide rod 56 .

[0029] Specifically, a fixing bar 59 is fixedly connected to the surface of the guide rod 56 , and the fixing bar 59 is sleeved and connected to the surface of the stud 52 . A bracket 510 is fixedly connected to the upper surface of the engine group 3 , and a rotating motor 511 is fixedly connected to the surface of the bracket 510 .

[0030] Specifically, the driving end of the rotating motor 511 is rotatably connected to the rotating shaft 512 , and the surface of the rotating shaft 512 is fixedly connected to the first gear 513 .

[0031] Specifically, a second gear 514 is fixedly connected to the surface of the stud 52 . The second gear 514 is disposed below the fixing bar 59 . The second gear 514 is gear-driven with the inner wall of the first gear 513 .

[0032] The effects achieved by the above components are as follows: by providing the stud 52, it is convenient to drive the sleeve column 53 to move up and down, so that the sleeve column 53 drives the protective cover 54 to move up and down, and the protective cover 54 is provided to facilitate shielding the heat dissipation slot 51 to prevent rain from passing through the heat dissipation slot 51 to erode the internal components of the engine group 3, and to provide sliding between the connecting block 58 and the guide rod 56 to facilitate the sleeve column 53 to move up and down stably along the surface of the guide rod 56, so as to prevent the sleeve column 53 and the stud 52 from rotating synchronously, so that they are relatively prohibited, resulting in the height of the protective cover 54 cannot be adjusted, and an anti-slip block 57 is provided to facilitate preventing the sleeve column 53 from separating from the stud 52, and a fixing bar 59 is provided to facilitate preventing the sleeve column 53 from moving downward too far, resulting in friction between the sleeve column 53 and the second gear 514, causing damage to the equipment, and a rotating motor 511 is provided to facilitate driving the first gear 513 to rotate, thereby driving the second gear 514 to drive the screw to rotate, thereby adjusting the height of the protective cover 54.

[0033] Working principle: By setting up the protective device 5, it is convenient to use the protective cover 54 when protecting the engine group 3. The rotating motor 511 drives the rotating shaft 512 to rotate, thereby transmitting the first gear 513 and the second gear 514, and then drives the stud 52 to rotate, so that the stud 52 and the inner side of the sleeve 53 are transmitted, so that the sleeve 53 is adjusted to rise and fall vertically along the surface of the guide rod 56. When the weather is clear, the protective cover 54 can be raised to the top, so that the heat dissipation groove 51 can dissipate heat and ventilation for the engine group 3, and the protective cover 54 can shade the engine group 3.

[0034] When encountering thunderstorm weather, the sleeve column 53 drives the protective cover 54 to move downward, so that when the stud 52 drives the sleeve column 53 to move downward, the surface of the sleeve column 53 collides with the fixing bar 59, preventing the sleeve column 53 from moving downward too much and colliding with the surface of the second gear 514, causing damage. At the same time, it also drives the protective cover 54 to cover the heat dissipation groove 51, preventing rainwater from penetrating into the inner wall of the engine group 3 through the heat dissipation groove 51. By setting up the protective device 5, it is convenient to protect the engine group 3, avoiding the fact that most of the existing engine groups 3 have heat dissipation holes on the surface. When thunderstorm weather occurs, the engine group 3 is eroded by rainwater for a long time, and the rainwater will enter the interior of the engine group 3, causing corrosion damage to equipment parts, thereby effectively improving the safety of the equipment.
