[0034] It also includes a first baffle 4 and a second electric slider 103; a humidity sensor is provided outside the fixed rod 1; a groove 1005 is provided on the fixed rod 1; two second electric sliders 103 are slidably connected on the groove 1005; the first baffle 4 is fixedly connected to the inner side of the two second electric sliders 103; the barrier net 3 is attached to the inner side of the first baffle 4.

[0035] It also includes a guide cover 104, an elastic cloth 106, and a one-way membrane 109; the guide cover 104 is slidably connected inside the fixing rod 1; the elastic cloth 106 is fixedly connected to the lower side of the guide cover 104; a plurality of holes are equally spaced on the elastic cloth 106, and a membrane is provided in each hole; a plurality of one-way membranes 109 are fixedly connected inside the fixing rod 1; each one-way membrane 109 opens downwards, and each one-way membrane 109 is located in an adjacent first connecting hole 1003.

[0036] The top plate 105 is also included; the guide cover 104 is fixed with two top plates 105.

[0037] The fixed rod 1 is provided with a receiving groove 1001; the receiving groove 1001 is located directly below the barrier net 3.

[0038] Each top plate 105 is provided with a plurality of top beads.

[0039] The first cover 4 is made of high thermal conductivity material.

[0040] The receiving groove 1001 is provided with a scraping piece on the upper side.

[0041] After the fixed rod 1 is firmly fixed to the ground by bolts, the airflow at a high altitude blows towards the fan blade 2 to make it rotate, when the fan blade 2 rotates, the mechanical energy generated by the rotating shaft of the fan blade 2 is transmitted to the generator 5 through the transmission device, so that the generator 5 generates electricity, in this process, considering that the generator 5 is easy to generate heat under the condition of continuous work, and the existing installation method is to set the generator 5 in the fixed rod 1, then open the heat dissipation hole to dissipate heat through the external exhaust structure, but this way not only causes the heat dissipation hole to be blocked, and because it is the air circulation in the shell, the shell of the generator 5 is complex and covers a wide range, so the heat transfer rate is slow, therefore, in order to improve the heat dissipation effect of the equipment, rectangular grooves are opened on the front side and the rear side of the fixed rod 1, so that the generator 5 is in contact with the external airflow, and the generator 5 in contact with the external airflow is blown by the external strong airflow, so that the heat generated by the generator 5 under work is directly taken away from the rear side of the fixed rod 1, compared with the existing heat dissipation method, the energy consumption of the equipment is reduced, and at the same time, it is not limited to the flow channel heat dissipation in the fixed rod 1, and the rectangular grooves are opened on the front side and the rear side of the fixed rod 1, so that the external airflow can directly blow to the generator 5, and the external airflow circulation can directly act on all parts of the generator 5, and the airflow flow is not easy to be hindered by the generator 5, so as to improve the heat dissipation effect of the equipment, at the same time, when used in the northwest region with more wind and sand, the blocking net 3 is added to intercept the wind and sand and dust, so as to avoid the erosion of the generator 5 by the wind and sand, and prolong the service life of the generator 5, and the blocking net 3 is used to intercept the wind and sand and dust, and the long-term use of the blocking net 3 will cause the surface of the blocking net 3 to be blocked by the wind and sand and dust, so that the airflow is difficult to blow to the generator 5 through the blocking net 3, thereby affecting the heat dissipation effect of the generator 5, therefore, from top to bottom, the first electric sliding block 102 is driven to rotate clockwise on the sliding rail 101, thereby driving the blocking net 3 to rotate clockwise, it should be noted that part of the blocking net 3 is hidden in the fixed rod 1 and does not contact the outside in the initial state, therefore, when the blocking net 3 rotates, the area of the blocking net 3 hidden by the fixed rod 1 leaks out, and there is no wind and sand and dust adhered to the area, and when the area hidden by the blocking net 3 rotates out, that is, rotates to the rectangular groove area opened by the fixed rod 1, the blocking net 3 can continue to intercept the wind and sand and dust in the outside, at this time, the airflow passing through the blocking net 3 blows to the generator 5, thereby improving the adaptability of the equipment, at the same time, in the rotating process of the blocking net 3, the blocking net 3 contacts the inner wall of the fixed rod 1, and the wind and sand and dust adhered to the blocking net 3 are scraped off by the fixed rod 1, so as to realize the self-cleaning effect of the equipment on the blocking net 3.

[0042] After the rectangular slot on the front side and the rear side of the fixed rod 1 is communicated with the outside, when the subsequent workers need to maintain and observe the generator 5, since the storage slot 1001 is located directly below the barrier net 3, the barrier net 3 can be removed from the first electric sliding block 102, and the barrier net 3 is pushed into the storage slot 1001, so that the rectangular slot on the front side and the rear side of the fixed rod 1 is not blocked, thereby facilitating the workers to maintain and observe the generator 5, and facilitating the subsequent maintenance work of the workers.

[0043] It is also considered that, in order to ensure that the generator 5 is cooled in a slow wind speed environment, when the wind speed sensor in the fixed rod 1 detects that the external airflow is weak, the wind speed sensor sends an electric signal to control the fan 108 to rotate, so that the external airflow is sucked into the air slot 1002 through the filter screen 107, and then blown to the generator 5 from the first connecting hole 1003 and the second connecting hole 1004 under the action of the fan 108, thereby cooling the generator 5, and finally discharged to the outside through the barrier net 3. In this process, since the airflow is discharged from the inside of the barrier net 3 to the outside, the fan 108 can be used to cool the generator 5 while cleaning the barrier net 3, and the residual sand and dust on the barrier net 3 is blown back to the outside, thereby improving the cooling effect of the equipment and further improving the cleaning effect of the barrier net 3. When the wind speed sensor detects that the external wind speed is large, the fan 108 can be controlled to stop rotating by sending an electric signal, and the equipment is cooled by natural convection. At the same time, the fan 108 can be controlled to reverse by timing, so that the gas enters from the rectangular slot on the front side and the rear side of the fixed rod 1, then enters from the first connecting hole 1003 and the second connecting hole 1004, and finally blows to the filter screen 107 under the rotation of the fan 108, thereby realizing the reverse cleaning function of the filter screen 107, avoiding the blockage of the filter screen 107 during use. It should be noted that since the upper side of the storage slot 1001 is provided with a scraping blade, the dust remaining on the surface of the barrier net 3 can be scraped off by the scraping blade on the upper side of the storage slot 1001 during the process of pushing the barrier net 3 into the storage slot 1001, thereby avoiding the dust entering the inside of the filter screen 107 from the storage slot 1001, and avoiding the dust being carried by the airflow when the fan 108 cools the generator 5.

[0044] When facing the wind and sand weather, the blocking net 3 can be shielded. When facing the rain, the mesh of the blocking net 3 is difficult to block the penetration of rainwater, resulting in the erosion of the generator 5 by rainwater. Therefore, when the humidity sensor outside the fixed rod 1 detects that the humidity outside is too large, taking the view from top to bottom as the basis, the second electric sliding block 103 is started to rotate counterclockwise on the sliding groove 1005. When the first cover 4 rotates by 90 degrees, the second electric sliding block 103 stops rotating. At this time, the first cover 4 after rotation covers the rectangular slot on the front side and the rear side of the fixed rod 1, and then cooperates with the fixed rod 1 to completely enclose the blocking net 3 and the generator 5. It should be noted that: since the first cover 4 is made of high thermal conductivity material, the rainwater flowing on the surface of the first cover 4 can take away the heat on the surface of the first cover 4. That is, the heat generated by the generator 5 can be taken away by the flow of rainwater, so that the rainwater cannot penetrate to contact the generator 5, and at the same time the heat dissipation effect can be guaranteed, preventing the generator 5 from being corroded by rainwater and improving the protection ability of the equipment. When the humidity sensor detects that the humidity outside is small, the second electric sliding block 103 is continued to rotate counterclockwise by 90 degrees to reset, so that the equipment is cooled by the natural air flow.

[0045] It is also considered that when the fan 108 actively cools the generator 5, the air flow is easily directly discharged from the rectangular grooves on the front and rear sides of the fixed rod 1 after passing through the first connecting hole 1003 and the second connecting hole 1004, resulting in that the air flow cannot completely cover the barrier net 3 and blow to the barrier net 3, so that the effect of backflushing cleaning the barrier net 3 is poor. Therefore, when the fan 108 is used for cooling, a one-way membrane 109 is additionally arranged on each first connecting hole 1003, and the one-way membrane 109 is only opened downward, so that the air flow introduced upward by the fan 108 cannot flow out of the first connecting hole 1003. Then, the elastic cloth 106 covers all the second connecting holes 1004. When the gas continuously flows into the elastic cloth 106 from the second connecting hole 1004, the elastic cloth 106 is gradually lifted upward under the action of the air flow, thereby driving the guide cover 104 to move upward. When the elastic cloth 106 is unfolded to the limit, the fan 108 continues to fill air into the elastic cloth 106. At this time, the diaphragm on the elastic cloth 106 is lifted by the air pressure, so that the gas is sprayed out of the hole on the elastic cloth 106. It should be noted that the limit unfolding height of the elastic cloth 106 is equal to the height of the barrier net 3, so that the sprayed air flow can uniformly spray to the barrier net 3, thereby covering the barrier net 3, so as to improve the cleaning effect of the device on the barrier net 3. At the same time, the elastic cloth 106 covers the generator 5 when it is unfolded to the limit. When the air flow is not sprayed out of the hole of the elastic cloth 106, the air flow flows upward along the surface of the generator 5 under the limitation of the elastic cloth 106, and then is sprayed out of the hole of the elastic cloth 106. The air flow adhering to the surface of the generator 5 carries away the heat on the surface of the generator 5, and finally is discharged from the hole of the elastic cloth 106, thereby further improving the cooling effect of the device on the generator 5. Since the one-way membrane 109 is only opened downward, when the fan 108 is reversed, the external air flow can normally pass through the first connecting hole 1003 through the negative pressure on the lower side of the one-way membrane 109, thereby ensuring the back cleaning effect on the filter screen 107.

[0046] It is also considered that in the process of lifting the guide cover 104 by the elastic cloth 106, the guide cover 104 also synchronously drives the top plate 105 to move upward. Under the movement of the top plate 105, the top plate 105 extrudes the part leaked by the barrier net 3, so that the sand and stones stuck in the barrier net 3 are separated from the mesh of the barrier net 3 under the extrusion of the top plate 105, thereby avoiding that the stuck sand and stones affect the normal rotation of the barrier net 3, and improving the adaptability of the device. Further, the top bead arranged on the top plate 105 extrudes the mesh of the barrier net 3, thereby improving the cleaning effect of the top plate 105 on the sand and stones.

[0047] Embodiment 2

[0048] On the basis of embodiment 1, as Figure 1 , Figure 7 and Figure 8As shown, the second cover 201 is further included; the outer surface of the fixed rod 1 is fixedly connected with the second cover 201.

[0049] When encountering the scene of raining, rainwater is easy to flow along the surface of the fixed rod 1 to the filter screen 107, causing the rainwater to penetrate the filter screen 107 into the internal equipment, thereby damaging the internal circuit of the equipment. In order to avoid this phenomenon, the second cover 201 is used to shield the filter screen 107 when it rains, preventing the rainwater from directly entering the fixed rod 1 through the filter screen 107, avoiding water seepage in the internal fixed rod 1, and improving the protection effect of the equipment.
