As shown in Figures 4, 5, 6, 7 and 8, the energy storage mechanism 2 includes a fan blade 25, the inner end of the fan blade 25 is fixedly connected to the rotating shaft 24, the end of the rotating shaft 24 away from the fan blade 25 is drivingly connected to the generator 23, the end of the generator 23 away from the rotating shaft 24 is fixedly connected to the transmission member 210, the end of the transmission member 210 away from the generator 23 is fixedly connected to the energy storage box 29, a traction plate 20 is provided between the energy storage box 29 and the generator 23, and the outer side of the rotating shaft 24 is connected to the cabinet 2 through bearings. 1 and a fixed plate 26, the two sides of the cabinet 21 are symmetrically connected with the guide plate 22, the fixed plate 26 is fixedly connected to the outside of the cabinet 21, the end of the fixed plate 26 away from the cabinet 21 is fixedly connected to the reinforcement rod 27, the end of the reinforcement rod 27 away from the fixed plate 26 is rotatably connected to the ring rail 28, the ring rail 28 is fixedly connected to the inner side of the fan blade 25, one end of the cabinet 21 is fixedly connected to the air outlet component 201, the end of the cabinet 21 away from the air outlet component 201 is fixedly connected to the frame plate 203, the central part of the frame plate 203 The motor 204 is connected to the cabinet 21 through a bearing, and the output end of the motor 204 is connected to the blade 205 through a coupling. A filter screen 202 is arranged at the end of the blade 205 away from the motor 204, and the filter screen 202 is fixedly connected to the outside of the cabinet 21. A double-headed rod 206 is fixedly connected to the outside of the motor 204, and the end of the double-headed rod 206 away from the motor 204 is fixedly connected to the inside of the cabinet 21. A frame sleeve 207 is fixedly connected to the inside of the cabinet 21, and the motor 204 is arranged inside the frame sleeve 207. The frame sleeve 207 One end away from the cabinet 21 is fixedly connected with a reducer 208, and by starting the motor 204, the blade 205 connected thereto by a coupling will rotate, and then the wind will pass through the filter 202 and enter the frame sleeve 207, and the frame sleeve 207 is fixedly connected with a plurality of reducers 208, and the wind has and only has to be discharged from the reducer 208, and the air inlet port diameter of the reducer 208 is larger than the air outlet port diameter, so when the wind enters the bottle from the large mouth, the air is compressed and the air flow speed is accelerated. When going out from the small mouth, due to the limitation of the small mouth, the air flow will be further accelerated, and the kinetic energy of the air molecules will be increased during the air flow acceleration process. According to the principle of thermodynamics, the temperature will decrease when the kinetic energy of the gas increases, thereby realizing the secondary cooling treatment of the wind. The wind will then first cool the generator 23, and then blow along the traction plate 20 to the energy storage box 29 and the transmission member 210. Because the interface usually has a larger contact resistance than the main body of the line due to factors such as the connection process and the flatness of the contact surface, more heat will be generated when the current passes through, so it needs to be cooled to reduce energy loss. At the same time, the temperature of the energy storage box 29 will increase during the power transportation process, and excessive temperature will aggravate the generation of self-discharge, so cooling and maintaining a constant temperature can reduce the degree of self-discharge.

Since heat will float upward, the air outlet assembly 201 located in the upper part of the cabinet 21 will discharge the waste gas and hot air to the outside.

The end of the transmission line 2104 away from the plug-in port 2103 is fixedly connected to the energy storage box 29. A hollow screw 2106 is connected to the outer side of the plug-in port 2103 through a bearing. When wind blows on the fan blades 25, the fan blades 25 will rotate with the rotating shaft 24. Then the generator 23 connected to the other end of the rotating shaft 24 will start to operate to convert mechanical energy into electrical energy. At the same time, the transmission member 210 connected to the other side of the generator 23 will transmit the electrical energy to the outside and be stored in the energy storage box 29, wherein the transmission member 210 includes a connection port 2102, and the connection port 2102 is connected to the generator 23. Therefore, the operator inserts the plug-in port 2103 connected to the transmission line 2104 into the connection port 2102, wherein the plug-in port 2103 is not fully inserted into the connection port 2102, and then rotates forward to connect the plug-in port 2103 to the transmission line 2104. The outer side of the hollow screw 2106 is connected to the inner thread sleeve 2105 by a bearing. At this time, the outer side of the hollow screw 2106 will move inward along the inner thread sleeve 2105, and the plug-in port 2103 will be completely inserted into the connection port 2102. Compared with the single plug-in type, the external threaded connection can provide a stronger mechanical bonding force, so that the connection is not easy to loosen, and can maintain good stability under vibration, impact and other conditions; at the same time, it can also avoid the possibility of loose connection during long-term operation, resulting in poor contact, further increasing the contact resistance and heating effect. The outer thread of the hollow screw 2106 is connected with an internal thread Sleeve 2105, the internal threaded sleeve 2105 is fixedly connected to the outside of the generator 23, the outside of the hollow screw 2106 is fixedly connected with a hexagonal nut 2107, the outside of the hexagonal nut 2107 is inserted with a limiting rod 2108, the outside of the limiting rod 2108 is fixedly connected with a ring sleeve 2109, the inner end of the limiting rod 2108 is squeezed and fitted with the circular groove 2101, and the operator also passes the limiting rod 2108 through the hexagonal nut 2107 and squeezes it into the circular groove 2101, wherein the distance between the inner diameter and the outer diameter of the circular groove 2101 is smaller than the diameter of the limiting rod 2108, which serves to increase the stability of the interface connection.

As shown in Figures 9, 10, 11, 12, 13 and 14, the stabilizing mechanism 3 includes a partition 31, which is fixedly connected to the inner side of the cabinet 21, and the top of the partition 31 is fixedly connected to the generator 23, the energy storage box 29 and the traction plate 20 respectively.

In addition, when the wind force is too strong, the wind will blow on the force-bearing disk 33 and move the cross bar 34 inward, wherein the force-bearing disk 33 is tough, and the inclined pressure block 32 connected to the other end of the cross bar 34 will squeeze the top of the reset member 36, wherein the reset spring 35 fixedly connected to the outer side of the inclined pressure block 32 plays a role in resetting it, and then the reset member 36 will move downward and squeeze the inner frame 37 downward, and then the center plug 38 and the side plug 39 fixedly connected to the bottom of the inner frame 37 will move downward accordingly and be deeply inserted into the soil, thereby playing a role in increasing the stability of the entire equipment.

In addition, the expansion plate 317 connected to both sides of the epitaxial block 311 by the inner shaft 316 will be pushed out by the spring bar 318 during the process of the epitaxial block 311 extending outward. The first magnet 314 and the second magnet 315 maintain a repulsive relationship, and the two play a role in resetting the ring frame 312, and ultimately play a role in increasing the contact area between the entire equipment and the ground and strengthening the stabilization of the structure. The end of the spring bar 318 away from the expansion plate 317 is fixedly connected to the inner side of the epitaxial block 311.

When the present invention is in use: first, when it rains, the rain will hit the shielding plate 11. If the rain is too much and heavy, the rain will flow along the top of the shielding plate 11 and hit the storage frame 16. Then the extension plate 15 fixedly connected to the bottom of the storage frame 16 will move downward along the inner rail 14. At this time, the extension plate 15 will be pulled out from the shielding plate 11, thereby achieving the purpose of increasing the shielding range. When the wind blows on the fan blades 25, the fan blades 25 will rotate with the shaft 24, and then the generator 23 connected to the other end of the shaft 24 will operate to convert mechanical energy into electrical energy. At the same time, the transmission member 210 connected to the other side of the generator 23 will transmit the electrical energy outward and be stored in the energy storage box 29.

In addition, when the wind is too strong, the wind will blow on the force-bearing disk 33 and move the cross bar 34 inward, and the oblique pressure block 32 connected to the other end of the cross bar 34 will squeeze the top of the reset member 36, causing the reset member 36 to move downward and squeeze the inner frame 37 downward, and then the center plug 38 and the side plug 39 fixedly connected to the bottom of the inner frame 37 will move downward and deeply inserted into the soil. At the same time, in the process of the reset member 36 moving downward, it will also squeeze the extension block 311 outward, causing the ring frame 312 fixedly connected to the outside of the extension block 311 to move outward along the side rail 313, and then the extension block 311 will extend from the bottom frame shell 301, and at the same time, the expansion plate 317 connected to the two sides of the extension block 311 through the inner shaft 316 will be pushed out by the elastic bar 318.
