[0014] As a further technical solution of this utility model, the heat sink is arranged at equal intervals, and there is a distance between the heat sink and the side connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the tower clearance monitoring equipment for wind turbine generator operation and maintenance not only realizes the function of easy installation and fixing, but also realizes the function of free energy storage, and also realizes the function of improving heat dissipation;

[0016] (1) The video monitoring equipment consists of a base plate and a power supply housing, and is equipped with a mounting plate, side connecting plate, through hole, fixing head, limit rod, outer sleeve head and mounting hole. The wiring head at the top of the base plate is electrically connected to the main control box at the top of the tower, so that the ventilation slot at the bottom of the base plate records the tail wave frequency of the impeller, so as to provide visual support for wind turbine operation and maintenance. During installation, the steel strand is first passed through the through hole in the side connecting plate to strengthen the stability of the mounting plate installation position. Then, the limit rod in the top fixing head is placed at the installation position at the top of the tower, and the bolt is connected to the mounting hole to fix the mounting plate. Then, the outer sleeve head on the left and right sides of the top plate of the base plate is connected to the mounting hole so that the monitoring equipment is installed at the front end of the mounting plate, which further increases the stability of the monitoring equipment installation. The mounting plate makes the installation of the base plate simpler and strengthens the monitoring equipment in the high-altitude installation state, realizing the function of easy installation and fixing.

[0017] (2) By setting up a support, solar panel, movable plate, through groove, power line, storage battery, and circuit board, the monitoring equipment mainly records the wind turbine impeller through the probe and then transmits the signal. The solar panel on the support at the top of the top plate absorbs solar energy and converts solar energy into electrical energy through the power line inside the through groove. The circuit board inside the storage battery is connected to the power line so that the circuit board can store electrical energy in the storage battery. The movable plate isolates the electrical components inside the through groove to prevent the monitoring equipment from being temporarily powered off due to accidents, which would cause the probe to stop recording. The monitoring equipment is more flexible and more applicable, and realizes the function of free energy storage.

[0018] (3) The detector head at the bottom of the base plate is electrically connected to the main control box at the top of the tower by means of heat conduction plate, inner groove, heat sink, and fins. When in use, the monitoring equipment itself will generate heat. The heat inside the monitoring equipment is concentrated by the heat conduction plate on the left and right sides of the base plate. The heat conduction plate and the heat sink are connected. Finally, the heat is dissipated through the heat sink connected by the fins, preventing heat from accumulating inside the power supply shell and causing damage to the monitoring equipment. This reduces the heat accumulation when the monitoring equipment is in use, further enhances the heat dissipation effect, and realizes the function of improving heat dissipation.

[0028] Specifically, such as Figure 1 and Figure 2As shown, the video monitoring equipment consists of a base plate 1 and a power supply housing 2. The terminal block 6 at the top of the base plate 1 is electrically connected to the main control box at the top of the tower, so that the ventilation slot 3 at the bottom of the base plate 1 records the tail wave frequency of the impeller, providing visual support for wind turbine operation and maintenance. During installation, the steel strand is first passed through the through hole 9 in the side connecting plate 8 to enhance the stability of the mounting plate 7. Then, the limiting rod 11 in the fixing head 10 at the top of the 8 is placed at the installation position on the top of the tower, and the bolts are connected to the mounting hole 13 to fix the mounting plate 7. Then, the outer sleeve head 12 on both sides of the top plate 5 at the top of the base plate 1 is connected to the mounting hole 13 so that the monitoring equipment is installed on the front end of the mounting plate 7, which further increases the stability of the monitoring equipment installation.

[0030] Specifically, such as Figure 1 and Figure 3 As shown, the monitoring equipment mainly records the wind turbine impeller through the probe 4 and then transmits the signal. The solar panel 15 on the support 14 at the top of the top plate 5 absorbs solar energy and converts the solar energy into electrical energy through the power line 18 inside the channel 17. The circuit board 20 inside the battery 19 is connected to the power line 18 so that the circuit board 20 can store electrical energy in the battery 19.

[0032] Specifically, such as Figure 1 and Figure 4As shown, the probe 4 at the bottom of the base plate 1 is electrically connected to the main control box at the top of the tower. During use, the monitoring equipment itself generates heat. The heat inside the monitoring equipment is concentrated by the heat conduction plates 21 on the left and right sides of the base plate 1. The heat conduction plates 21 are connected to the heat sinks 23. Finally, the heat is dissipated through the heat sinks 23 connected by fins 24, preventing heat from accumulating inside the power supply casing 2 and damaging the monitoring equipment, thus reducing the heat accumulation during the use of the monitoring equipment.

[0033] Working Principle: In use, the video monitoring device consists of a base plate 1 and a power supply housing 2. The connector 6 at the top of the base plate 1 is electrically connected to the main control box at the top of the tower, allowing the ventilation slot 3 at the bottom of the base plate 1 to record the tail-end fluctuation frequency of the impeller, providing visual support for wind turbine operation and maintenance. During installation, the steel strand is first passed through the through hole 9 in the side connecting plate 8 to enhance the stability of the mounting plate 7. Then, the limiting rod 11 in the fixing head 10 at the top of the 8 is placed at the installation position on the top of the tower, and bolts are inserted into the mounting holes 13 to fix the mounting plate 7. The outer sleeves 12 on both sides of the top plate 5 at the top of the base plate 1 are then connected to the mounting holes 13, allowing the monitoring device to be installed on the front end of the mounting plate 7, further increasing the stability of the monitoring device installation. The mounting plate 7 simplifies the installation of the base plate 1. The monitoring device mainly records the wind turbine impeller through the probe 4 and then transmits the signal. Solar energy is absorbed by the solar panel 15 on the support 14 at the top of the top plate 5, and converted into electrical energy by the power line 18 inside the through slot 17. The circuit board 20 inside the battery 19 is connected to the power line 18 so that the circuit board 20 can store electrical energy in the battery 19. The various electrical components inside the through slot 17 are isolated by the movable plate 16 to prevent the monitoring equipment from being temporarily powered off due to accidents, which would cause the recording of the probe 4 to stop. The monitoring equipment is more flexible in use. The probe 4 at the bottom of the base plate 1 is electrically connected to the main control box at the top of the tower. When in use, the monitoring equipment itself will generate heat. The heat is concentrated inside the monitoring equipment by the heat conduction plates 21 on the left and right sides of the base plate 1. The heat conduction plates 21 are connected to the heat sinks 23. Finally, the heat is dissipated through the heat sinks 23 connected by fins 24, preventing heat from accumulating inside the power supply casing 2 and damaging the monitoring equipment, and reducing the heat accumulation when the monitoring equipment is in use.
