When the propeller blades stop rotating, the pushing block will also stop rotating to push the shielding fixing plate away from each other, and finally the elastic force of the two first connecting springs will be released to push the two shielding fixing plates to move towards each other to block and fix the two sides of the bottom of the monitoring camera.

At the same time, the rotation of the active bevel gear 505 can drive the sand blowing component 4 to rotate to blow sand and dust from the mirror surface in front of the monitoring camera 3.

[0023] like Fig. 9 As shown, the sand blowing assembly 4 includes a mounting block 401, sand blowing blades 402 and a driven bevel gear 403; The mounting block 401 is fixedly mounted on the bottom of the drone frame 1 and on the outside of the front end of the monitoring camera 3, the sand blowing blades 402 are movably sleeved on the bottom of the mounting block 401, the driven bevel gear 403 is fixedly sleeved on the top of the sand blowing blades 402 and on the outside of the mounting block 401, and the surface of the driven bevel gear 403 is meshed with the surface of the active bevel gear 505.

[0027] like Figure 7 and Fig. 9 As shown, the other end of the first connecting spring 703 is fixedly connected to the inner wall of the drone frame body 1 , and the inner wall of the first connecting spring 703 is movably connected to the surface of the limiting rod 701 .

[0028] The above scheme is adopted: by providing a first connecting spring 703, due to the elastic force of the two first connecting springs 703, the two shielding fixing plates 702 can be pushed to move towards each other, so that when the monitoring camera 3 is subsequently stored in the inner cavity of the drone frame 1, the two sides of the bottom of the monitoring camera 3 can be blocked.

[0029] like Figure 4 and Figure 8 As shown, the pneumatic assembly 12 includes a pneumatic slot 1201, a pneumatic rod 1202 and a second return spring 1203; The pneumatic groove 1201 is opened inside the drone frame 1 and on both sides of the monitoring camera 3.

The second return spring 1203 is fixedly installed between the top of the pneumatic rod 1202 and the inner wall of the pneumatic groove 1201.

[0030] By adopting the above solution: by providing a second return spring 1203, when the blocking and fixation of the bottom two sides of the monitoring camera 3 are released, the elastic force of the second return spring 1203 will be released, thereby pushing the pneumatic rod 1202 to drive the monitoring camera 3 as a whole to extend downward smoothly.

[0031] like Figures 1 to 4 As shown, a support frame 8 located on both sides of the monitoring camera 3 is fixedly installed at the bottom end of the drone frame 1.

[0032] By adopting the above solution, by providing the support frame 8, when the entire drone frame body 1 is to land, it can be supported by the two support frames 8 after landing.

[0033] like Figure 5 As shown, a buffer assembly 9 is provided at the bottom of the support frame 8, and the buffer assembly 9 includes a rubber sleeve 901, an air bag 902 and an air cylinder 903; The rubber sleeve 901 is fixedly installed at the bottom of the support frame 8 , the airbag 902 is arranged in the inner cavity of the rubber sleeve 901 , and the air cylinder 903 is fixedly installed inside the support frame 8 and at the middle of the top of the airbag 902 , and is connected with the top of the airbag 902 .

[0034] The above solution is adopted: by providing the airbag 902, when the entire rubber sleeve 901 contacts the ground, the impact force will squeeze the airbag 902 to introduce the gas into the air cylinder 903, so that the impact pressure is released.

[0035] like Figure 5 As shown, the inner cavity of the gas cylinder 903 is provided with an auxiliary buffer component 10, and the auxiliary buffer component 10 includes a first piston block 101, a first return spring 102 and a one-way valve disc 103; The first piston block 101 is movably sleeved in the inner cavity of the gas cylinder 903 , the first return spring 102 is fixedly installed between the top of the first piston block 101 and the inner wall of the gas cylinder 903 , and the one-way valve flap 103 is arranged in the middle of the first piston block 101 .

[0036] The above solution is adopted: by providing a first return spring 102, when the gas pushes the first piston block 101 upward, the first return spring 102 will be compressed, and when the gas pressure force disappears, the elastic force of the first return spring 102 will be released, thereby pushing the first piston block 101 to move downward as a whole and return to its original position.

[0037] like Figure 5 As shown, the inner cavity of the gas cylinder 903 is provided with an air supply assembly 11 located above the first piston block 101, and the air supply assembly 11 includes an air supply pipe 1101, a second piston block 1102 and a ventilation pipe 1103; The air supply pipe 1101 is fixedly installed on the top of the inner cavity of the air cylinder 903, the second piston block 1102 is movably connected to the inner cavity of the first piston block 101, the ventilation pipe 1103 is fixedly installed on the top of the support frame 8, and is fixedly connected to the top of the air supply pipe 1101, and the other end of the ventilation pipe 1103 is fixedly connected to the outer bottom of the pneumatic groove 1201.

[0038] The above scheme is adopted: by providing a ventilation pipe 1103, when the first piston block 101 is pushed by the gas so that the air supply pipe 1101 presses against the one-way valve disc 103 to open, the gas will enter the air supply pipe 1101, thereby pushing the second piston block 1102 upward, so that the gas at the top of the inner cavity of the air supply pipe 1101 is pushed through the ventilation pipe 1103 and introduced into the pneumatic groove 1201, so as to drive the pneumatic rod 1202 to pull the monitoring camera 3 upward to be stored in the inner cavity of the drone frame 1.

[0039] like Figure 5 As shown, a gas circulation assembly 13 is disposed inside the support frame 8 and is located on the back of the gas cylinder 903. The gas circulation assembly 13 includes a venting groove 1301, a one-way valve block 1302 and a second connecting spring 1303; The ventilation groove 1301 is opened inside the support frame 8 and on the back of the air cylinder 903, and the top end is connected to the top of the inner cavity of the air cylinder 903, and the bottom end is located on the back of the first piston block 101. The one-way valve block 1302 is movably installed at the bottom of the front end of the inner cavity of the ventilation groove 1301, and the second connecting spring 1303 is fixedly installed between the front end of the one-way valve block 1302 and the inner wall of the ventilation groove 1301.

[0040] The above scheme is adopted: by providing a ventilation groove 1301, when the first piston block 101 moves upward, it will push the gas at the top of the inner cavity of the air cylinder 903 into the ventilation groove 1301, and then push the one-way valve block 1302 forward, so that the gas enters the inner cavity of the airbag 902 through the gap of the one-way valve block 1302, so that the airbag 902 returns to its original state.

[0041] The working principle and use process of the present invention: First of all, the operation of the monitoring system can be controlled. Through the operation of fixed monitoring equipment and macro monitoring equipment, unmanned real-time monitoring of the beach can be carried out for a long time to obtain accurate and real-time beach data. In addition, the beach ecology can be modeled and dynamic trend analyzed, so as to grasp first-hand beach data and make timely decisions, and remind tourists of potential dangers at the first time. At the same time, corresponding mobile monitoring equipment can also be used to conduct regular comprehensive inspections and monitoring of the beach.

[0042] When the mobile monitoring device is used, its propeller blades 2 rotate to drive the drone frame 1 to fly as a whole. At this time, the two propeller blades 2 at the front end will drive the driving rod 501 and the first connecting arm 502 to rotate, so that the two transmission arms 503 can link the two second connecting arms 504 and the active bevel gear 505 to rotate, and will drive the pushing block 704 to push the shielding fixing plate 702 to move in opposite directions, thereby releasing the blocking fixation on the bottom of the monitoring camera 3, and then the elastic force of the second return spring 1203 will be released, and then the monitoring camera 3 will be pushed downward as a whole. Due to the meshing relationship between the second connecting arm 504 and the active bevel gear 505 surface, the active bevel gear 505 rotates to drive the driven bevel gear 403 and the sand blowing blades 402 to rotate, and finally the sand blowing blades 402 will blow away the flying sand and dust on the front mirror of the monitoring camera 3, and will fall to the top two sides of the guide plate 6 and slide down, and then the beach will be successfully monitored in real time through the monitoring camera 3.

[0043] Afterwards, when the operator controls the propeller blades 2 to stop rotating and the unmanned frame 1 lands as a whole, the rubber sleeve 901 will come into contact with the ground and generate an impact force, which will then squeeze the airbag 902, causing the airbag 902 to deform and push the gas to the air cylinder 903, thereby pushing the first piston block 101 upward until the first piston block 101 moves to above the bottom end of the ventilation groove 1301. When the first piston block 101 moves upward, the gas in the top inner cavity of the air cylinder 903 will be pushed into the inner cavity of the ventilation groove 1301, and then the one-way valve block 1302 will be pushed forward, and the gas introduced into the airbag 902 from the gap will be replenished and restored, thereby achieving buffering of the impact force.

[0044] Then, when the first piston block 101 is pushed upward by the gas, the bottom of the air supply pipe 1101 will push the one-way valve flap 103 downward to open, and then the gas will enter the bottom of the inner cavity of the air supply pipe 1101, thereby pushing the second piston block 1102 to move upward as a whole, so that the gas at the top of the inner cavity of the air supply pipe 1101 is introduced into the inner cavity of the pneumatic groove 1201 through the ventilation pipe 1103, so that the air pressure becomes larger and pushes the pneumatic rod 1202 to drive the monitoring camera 3 to move upward as a whole, and when the propeller blade 2 stops rotating, it will make The pushing block 704 stops rotating and pushing the shielding fixing plate 702 away from each other, so that the first connecting spring 703 pushes the shielding fixing plates 702 towards each other. Subsequently, when the monitoring camera 3 rises, the bottom end will squeeze the inner bottom slope of the shielding fixing plate 702 and drive the two shielding fixing plates 702 to move away from each other, and finally the monitoring camera 3 is completely stored in the bottom inner cavity of the drone frame 1, and is blocked and fixed on both sides of the bottom by the two shielding fixing plates 702 moving towards each other, so that the monitoring camera 3 is stored in the drone frame 1 for protection.
