[0025] The security monitoring device provided by the present invention is now described.

[0026] Please also read Figure 1 The safety monitoring device includes a support pole 1, a monitoring device, a wind power generation device 2, a battery and an adjusting device, wherein the support pole 1 is fixed on the ground; the monitoring device is arranged on the support pole 1, and the monitoring device is used to monitor the monitored position; the wind power generation device 2 is arranged on the top of the support pole 1, and the wind power generation device 2 has a plurality of rotating fans 203; the battery is arranged on the support pole 1, and the battery is electrically connected to the wind power generation device 2 and the monitoring device; the adjusting device is arranged on the support pole 1, and the adjusting device is connected to the fan 203 of the wind power generation device 2, and the adjusting device is used to detect the wind speed and drive the fan to rotate, and reduce the windward area of ​​the fan 203 when the wind speed increases, and increase the windward area of ​​the fan 203 when the wind speed decreases.

[0027] The beneficial effects of the safety monitoring device provided in this embodiment are as follows: compared with the prior art, the safety monitoring device provided in this embodiment reduces the windward area of ​​the fan 203 when the wind speed increases by setting an adjustment device, thereby reducing the thrust of the wind on the fan 203, thereby reducing the rotation speed of the fan 203, and preventing the excessively high rotation speed from damaging the wind power generation device 2; when the wind speed decreases, the windward area of ​​the fan 203 is increased, the thrust of the wind on the fan 203 is increased, the rotation speed of the fan 203 is increased, the power generation capacity of the wind power generation device 2 is increased, and the power supply safety of the monitoring device is ensured.

[0028] like Figure 1 As shown, the wind power generation device 2 includes a fixed wheel 201, a transmission shaft 202 and a plurality of fans 203. The fixed wheel 201 is fixed to the transmission shaft 202 through a plurality of connecting rods. One end of the fan 203 is rotatably arranged on the fixed wheel 201, and the fans 203 are evenly arranged along the circumference of the transmission shaft 202. One end of the transmission shaft is connected to the generator. The setting of the fixed wheel 201, on the one hand, provides an installation space for the fan 203. The setting of the transmission shaft 202 enables the transmission shaft 202 to drive the rotor of the generator to rotate when the fan 203 drives the transmission shaft 202 to rotate, thereby realizing power generation.

[0029] like Figure 2 and Figure 4 As shown, a mounting shell 204 is sleeved on the outer side of the transmission shaft 202, the front end of the transmission shaft 202 is fixed on the mounting shell 204, and a first adjustment chamber 205 is provided between the mounting shell 204 and the transmission shaft 202, an adjustment hole is opened on the mounting shell 204, an adjustment rod 206 is inserted in the adjustment hole, a part of the adjustment rod 206 extends out of the outer side of the mounting shell 204, and a part of the adjustment rod 206 is arranged in the first adjustment chamber 205, and an adjustment block 207 is provided at one end of the adjustment rod 206 extending out of the mounting shell 204. The fan 203 includes a fan blade 208 and a fan rod 209, one end of the fan rod 209 away from the transmission shaft 202 is rotatably arranged on the fixed wheel 201, and one end of the fan rod 209 close to the transmission shaft 202 is provided with an adjustment tube 210, the adjustment rod 206 is inserted in the adjustment tube 210, and a spiral adjustment groove 211 is provided on the inner wall of the adjustment tube 210, and the adjustment block 207 is inserted in the adjustment groove 211. When the adjusting rod 206 and the adjusting tube 210 are inserted, the adjusting block 207 and the adjusting slot 211 cause the adjusting tube 210 to rotate in the forward direction, thereby reducing the frontal area of ​​the fan 203. On the contrary, when the adjusting rod 206 and the adjusting tube 210 are pulled out, the adjusting block 207 and the adjusting slot 211 cause the adjusting tube 210 to rotate in the reverse direction, thereby increasing the frontal area of ​​the fan 203.

[0030] In this embodiment, the regulating device includes an anemometer 3 and a hydraulic drive mechanism 4. Figure 1As shown, the anemometer 3 is arranged above the fixed wheel 201, so that the fan 203 does not affect the wind speed measured by the anemometer 3. The anemometer 3 is connected to the hydraulic drive mechanism 4, and the power output end of the hydraulic drive mechanism 4 is connected to the adjustment rod 206. The hydraulic drive mechanism 4 can drive the adjustment rod 206 to extend into or out of the adjustment tube 210 according to the wind speed detected by the anemometer 3.

[0031] like Figure 3 , Figure 4 and Figure 6 As shown, the hydraulic drive mechanism 4 includes an input pipe 401 , a connecting pipe 402 , an input block 403 , a reset member 404 and hydraulic oil 405 . One end of the input pipe 401 is connected to the central rotating shaft 301 of the anemometer 3, the input block 403 is slidably arranged in the input pipe 401, the reset member 404 is fixedly arranged in the input pipe 401, and the reset member 404 is connected to the input block 403. When the rotation speed of the central rotating shaft 301 increases, the input block 403 can be moved away from the central rotating shaft 301 under the action of centrifugal force, and when the rotation speed of the central rotating shaft 301 decreases, the input block 403 can be driven by the reset member 404 to approach the central rotating shaft 301. The input pipe 401 is connected to the adjusting chamber through a connecting pipe. The diameter of the input pipe 401 is smaller than the diameter of the adjusting rod 206. The hydraulic oil 405 is filled in the adjusting chamber, the connecting pipe 402 and the input pipe 401 on the side of the input block 403 away from the central rotating shaft 301, and the input block 403 and the input pipe 401 are sealed.

[0032] In actual use, when the wind speed increases, the rotation speed of the central shaft 301 increases, and the input block 403 can move away from the central shaft 301 under the action of centrifugal force. The input block 403 will push the hydraulic oil 405 in the input pipe 401 to be discharged outside the output pipe. At this time, the hydraulic pressure in the first regulating chamber 205 increases, which will push the regulating rod 206 to extend out of the mounting shell 204, that is, the regulating rod 206 extends into the regulating pipe 210. On the contrary, when the wind speed decreases, the rotation speed of the central shaft 301 decreases, and the centrifugal force on the input block 403 decreases. Then, the input block 403 approaches the central shaft 301 under the action of the reset member 404, and then the hydraulic oil 405 outside the input pipe 401 is sucked into the output pipe. At this time, the hydraulic pressure in the first regulating chamber 205 decreases, which will pull the regulating rod 206 to be inserted into the mounting shell 204, that is, the regulating rod 206 is pulled out of the regulating pipe 210. Here, according to the principle of hydraulic transmission, when the cross-sectional area of ​​the adjusting rod 206 is N times the cross-sectional area of ​​the input pipe 401, the thrust of the hydraulic oil 405 on the adjusting rod 206 is also N times the thrust of the input block 403 on the hydraulic oil 405. In the actual setting process, as long as the cross-sectional area of ​​the adjusting rod 206 is much larger than the cross-sectional area of ​​the input pipe 401, the weak centrifugal force exerted on the input block 403 or the weak elastic force of the input block 403 given by the reset member 404 when the anemometer 3 rotates can be amplified, and the adjusting rod 206 can be driven to slide.

[0033] like Figure 6 and Figure 7 As shown, the reset member 404 includes a fixed plate 406 and a spring 407. The fixed plate 406 is circular, and the diameter of the fixed plate 406 is the same as the diameter of the input pipe 401. The fixed plate 406 and the input pipe 401 are coaxially arranged and fixed in the input pipe 401. One end of the spring 407 is fixed on the fixed plate 406, and the other end of the spring 407 is fixed on the adjustment block 207. The fixed plate 406 is provided with a plurality of fluid holes 408. The arrangement of the fixed plate 406 and the spring 407 can facilitate the reset when the centrifugal force on the input block 403 is reduced. In addition, the arrangement of the fluid holes 408 prevents the fixed plate 406 from hindering the discharge or suction of the hydraulic oil 405.

[0034] like Figure 3 As shown, a pivot plate 409 is provided on the central shaft 301, the pivot plate 409 is circular, a plurality of input pipes 401 are provided, the input pipes 401 are formed in the pivot plate 409, a connecting box is provided on the outer cover of the pivot plate 409, each input pipe 401 is communicated with the inner cavity of the connecting box, and the connecting box is communicated with the top end of the connecting pipe 402. The setting of the pivot plate 409 can reduce the resistance of the hydraulic oil 405 to the input pipe 401 when the input pipe 401 rotates.

[0035] like Figure 1, a nacelle 5 is rotatably provided at the top of the support rod 1, a generator is arranged in the nacelle 5, a fixed cylinder 501 is fixed at the front end of the nacelle 5, one end of the fixed cylinder 501 is open, a mounting shell 204 is rotatably provided at the open end of the fixed cylinder 501, an inner cavity of the fixed cylinder 501 is communicated with the first regulating cavity 205, the inner cavity of the fixed cylinder 501 is filled with hydraulic oil 405, one end of the transmission shaft 202 extends to the sealed end of the fixed cylinder 501, a connecting pipe 402 is connected to the fixed cylinder 501, and a connecting pipe is provided on the leeward side of the fan 203. The setting of the fixed cylinder 501 can facilitate the rotation setting of the mounting shell 204. In addition, in the present invention, in addition to the mechanism improved by the present invention, the wind turbine also includes other necessary components, and the remaining components are all arranged in the nacelle 5. The remaining components of the wind turbine 2 are all prior art, and will not be repeated here.

[0036] like Figure 8 and Fig. 9 As shown, a guide tube 212 is provided in the first adjustment cavity 205, and a guide groove 213 is provided on the side wall of the guide tube 212. The guide groove 213 extends along the axial direction of the guide tube 212. A guide block 214 is provided at the bottom of the adjustment rod 206, and the guide block 214 is inserted into the guide groove 213. The provision of the guide tube 212 prevents the adjustment rod 206 from rotating during the sliding process, and facilitates driving the adjustment tube 210 to rotate.

[0037] Finally, a sealed box 6 is provided on one side of the support rod 1, and the battery is arranged in the sealed box 6. The setting of the sealed box 6 prevents the battery from being damaged by precipitation and dust. In the present invention, the monitoring device includes a camera 7, a mounting rod 101 is provided on the side wall of the support rod 1, a horizontally arranged mounting plate 102 is provided on the top of the mounting rod 101, and a camera 7 is provided at the bottom of the mounting plate 102.

Here, the storage device and the transmission device are also existing technologies, and the specific structure will not be repeated here. In order to facilitate the protection of the storage device and the transmission device, the storage device and the transmission device are also arranged in the sealed box 6.
