[0023] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0024] The explosion-proof drone according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0025] The explosion-proof drone provided in the embodiment of the present application can be used for aerial photography, agriculture and forestry, fire and monitoring of various assembly line equipment in factories, monitoring of various equipment in coal mines, and monitoring of fires caused by factory fires or explosions in coal mines. It is mainly used for monitoring the damage of tunnels and equipment in coal mines, and monitoring fire information caused by explosions in coal mines.

[0026] like Figure 1-Figure 4 As shown, the explosion-proof UAV of the embodiment of the present application may include a UAV body 10 , a shock absorbing device 20 , a plurality of protective mechanisms 30 and an adsorption device 40 .

[0027] The shock absorbing device 20 is detachably disposed at the bottom of the drone body 10 to cushion the landing of the drone body 10 .

[0028] Multiple protective mechanisms 30 are arranged in a circular array on the outer wall of the drone body 10. For example, the multiple protective mechanisms 30 can be 4, 5, 6, 7, 8, 9 protective mechanisms 30, etc. The specific number of protection mechanisms 30 can be selected according to actual conditions and is not limited here. Among them, the protective mechanisms 30 are used to protect the drone body 10.

[0029] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 3As shown, the protection mechanism 30 may include a support plate 31 , an arc-shaped elastic plate 32 and a buffer spring 33 .

[0030] The support plate 31 is detachably disposed on the drone body 10. It is understandable that the support plate 31 described in this embodiment is detachably disposed on the drone body 10, which facilitates the installation and replacement of the support plate 31. For example, the support plate 31 can be connected to the drone body 10 by means of snap connection, riveting or threaded fastener connection.

[0031] The arc-shaped elastic plate 32 is fixedly connected to the support plate 31, and the arc-shaped elastic plate 32 and the support plate 31 form an arch. It should be noted that the arc-shaped elastic plate 32 described in this embodiment can be an elastic metal sheet or can be made of rubber material.

[0032] One end of the buffer spring 33 is connected to the support plate 31 , and the other end of the buffer spring 33 is connected to the arc-shaped elastic plate 32 .

[0033] The drone body 10 is provided with an installation cavity 11 penetrating the top thereof. The adsorption device 40 is detachably arranged in the installation cavity 11 . The adsorption device 40 may include a supporting mechanism 41 , a driving mechanism 42 , a transmission mechanism 43 and a plurality of adsorption mechanisms 44 .

[0034] Among them, the support mechanism 41 is movably arranged in the installation cavity 11, the driving mechanism 42 is detachably arranged in the installation cavity 11, and the driving mechanism 42 is connected to the support mechanism 41 through the transmission mechanism 43, wherein the driving mechanism 42 is used to drive the support mechanism 41 to move up and down through the transmission mechanism 43.

[0035] Multiple adsorption mechanisms 44 are connected to the supporting mechanism 41 through a universal ball (not specifically marked in the figure). For example, the multiple adsorption mechanisms 44 can be 4, 5, 6, 7, 8, 9 adsorption mechanisms 44, etc. The specific number used can be selected according to actual conditions and is not limited here. Among them, the adsorption mechanism 44 is used to adsorb on the top wall of the space to be inspected to suspend the drone body 10.

[0036] It should be noted that the top wall of the space to be inspected described in this embodiment may be the top wall of a factory building or the top wall of a coal mine, and the top wall of the factory building or the top wall of a coal mine are both plane walls.

[0037] Furthermore, the multiple adsorption mechanisms 44 described in the above embodiment are connected to the support mechanism 41 through the universal ball (not specifically marked in the figure), which means that the body of the universal ball is fixedly connected to the support mechanism 41, and the universal ball of the universal ball is fixedly connected to the multiple adsorption mechanisms 44.

[0038] Further, in one embodiment of the present application, Figure 1-Figure 3As shown, the explosion-proof UAV may further include a plurality of obstacle avoidance sensors 50 and infrared cameras 60 .

[0039] Among them, a plurality of obstacle avoidance sensors 50 are arranged in a circumferential array on the outer wall of the drone body 10, and the plurality of obstacle avoidance sensors 50 are respectively electrically connected to the drone body 10, wherein the obstacle avoidance sensors 50 are used to sense the internal moving objects in the inspection space to control the drone body 10 to avoid obstacles. It should be noted that the moving object described in this embodiment may be a coal truck or other movable equipment.

[0040] The infrared camera 60 is arranged on the drone body 10, and the infrared camera 60 is wirelessly connected to the host computer (i.e., connected via a wireless network), wherein the infrared camera 60 is used to monitor the internal environment of the inspection space and send the monitoring data to the host computer (not shown in the figure). It should be noted that the host computer described in this embodiment refers to a computer that can directly issue control commands.

[0041] Specifically, when it is necessary to monitor the internal conditions of a coal mine, the relevant staff can control the drone body 10 to fly into the coal mine to be monitored through a controller (not shown in the figure). Then, the staff controls the driving mechanism 42 and drives the supporting mechanism 41 to move upward through the transmission mechanism 43. The supporting mechanism 41 moving upward drives multiple adsorption mechanisms 44 to extend out of the installation cavity 11 through the universal ball and extend to the top of the drone body 10.

[0042] Then, the staff controls the drone body 10 to fly upward and press the multiple adsorption mechanisms 44 against the inner wall of the coal mine shaft. As the drone body 10 drives the multiple adsorption mechanisms 44 to fly upward, the multiple adsorption mechanisms 44 are pressed and adsorbed on the inner wall of the coal mine shaft. That is, the drone body 10 is suspended on the inner wall of the coal mine shaft by the multiple adsorption mechanisms 44 adsorbed on the inner wall of the coal mine shaft. Then, the staff can control the propeller on the drone body to stop rotating. It can be understood that by stopping the propeller, the power loss of the drone body 10 can be saved, and then the endurance of the drone body 10 can be extended by hanging and staying to meet the inspection work under the coal mine.

[0043] At this time, the staff can use the infrared camera 60 to take pictures of the internal facilities around the coal mine, and transmit the photographed data to the host computer so that the relevant staff can analyze the monitored data, so that the staff can control the situation of the internal facilities and facilitate timely maintenance to prevent the occurrence of safety hazards.

[0044] In addition, when the drone body 10 flies into the coal mine, it can not only inspect the road conditions in the coal mine through the infrared camera 60, but also sense the moving objects in the coal mine through the multiple obstacle avoidance sensors 50 to control the drone body 10 to avoid obstacles. This can prevent the drone from being damaged by collision, thereby reducing the cost of use.

[0045] In addition, if the drone body 10 collides in a coal mine, the protection mechanism 30 can buffer the force of the drone body 10. That is, when the drone body 10 collides with an object, the arc-shaped elastic plate 32 in the protection mechanism 30 is first impacted, and the arc-shaped elastic plate 32 is deformed after being impacted and buffers part of the impact force. After the arc-shaped elastic plate 32 deforms and buffers part of the impact force, the deformation force generated by the arc-shaped elastic plate 32 is deformed and absorbed by the buffer spring 33, and then the remaining impact force is absorbed. In this way, the drone body 10 can be buffered and protected.

[0046] In one embodiment of the present application, Figure 2 As shown, the shock absorbing device 20 may include a base 21 , a plurality of shock absorbing mechanisms 22 and a plurality of supporting legs 23 .

[0047] Among them, the base 21 is arranged below the drone body 10, and multiple shock-absorbing mechanisms 22 are vertically distributed between the base 21 and the drone body 10. For example, the multiple shock-absorbing mechanisms 22 can be 4, 5, 6, 7, 8 shock-absorbing mechanisms 22, etc. The specific number of use can be selected according to actual conditions and is not limited here. One end of the shock-absorbing mechanism 22 is connected to the base 21, and the other end of the shock-absorbing mechanism 22 is connected to the drone body 10.

[0048] A plurality of support legs 23 are equidistantly fixed around the bottom wall of the base 21, and the support legs 23 are tilted. It should be noted that one end of the support leg 23 in this embodiment is fixedly connected to the bottom wall of the base 21, and the other end of the support leg 23 is tilted toward the outside of the drone body 10, and the tilt angle of the support leg 23 can be any value between 30 and 60 degrees.

[0049] It is understandable that the support feet 23 described in this embodiment are tilted on the bottom wall of the base 21, which can play a role of stable support. That is, when the drone body 10 is landing, the multiple tilted support feet 23 can support the drone body 10 more stably.

[0050] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 2 As shown, the shock absorbing mechanism 22 may include a buffer 221 and a spring 222 .

[0051] The buffer 221 is vertically arranged between the base 21 and the drone body 10, and one end of the buffer 221 is detachably connected to the base 21, and the other end of the buffer 221 is detachably connected to the drone body 10. It can be understood that the buffer 221 described in this embodiment can be connected to the base 21 and the drone body 10 respectively through threaded fasteners.

[0052] The spring 222 is sleeved on the buffer 221 , and one end of the spring 222 is connected to the base 21 , and the other end of the spring 222 is connected to the drone body 10 .

[0053] Specifically, when the staff controls the drone body 10 to land through the controller, the shock absorbing device 20 can buffer the force of the drone body 10 landing. That is, after the drone body 10 lands, it will first impact the support foot 23, and the support foot 23 will squeeze the spring 222 and the buffer 221 after being impacted. The spring 222 deforms to buffer the impact force, and the buffer 221 contracts to buffer the impact force, thereby providing force buffering protection for the landing of the drone body 10 and preventing the drone body 10 from being damaged by the impact force.

[0054] In one embodiment of the present application, Figure 4 As shown, the transmission mechanism 43 may include a rack 431 , a worm 432 , a worm wheel 433 and a gear 434 .

[0055] The rack 431 is fixedly disposed on the outer wall of the sleeve rod 411 , the worm 432 is rotatably disposed in the installation cavity 11 , and one end of the worm 432 is connected to one end of the driving mechanism 42 .

[0056] It should be noted that the driving mechanism 42 described in this embodiment can be a motor, the body of the motor can be connected to the inner wall of the installation cavity 11 through threaded fasteners (screws, bolts or screws), and the rotating shaft of the motor is connected to one end of the worm 432.

[0057] The worm wheel 433 and the gear 434 are coaxially and rotatably arranged in the installation cavity 11, wherein the worm wheel 433 is meshed with the worm 432, and the gear 434 is meshed with the rack 431. It should be noted that the worm wheel 433 and the gear 434 described in this embodiment are respectively fixedly arranged on the same support shaft (not specifically marked in the figure), and the support shaft is rotatably arranged in the installation cavity 11.

[0058] Specifically, when it is necessary to temporarily fix the drone body 10 on the inner wall of the shaft of a coal mine, the staff can control the motor (driving mechanism 42) to start through the controller, and the started motor drives the worm 432 to rotate, and the rotating worm 432 drives the worm wheel 433 to rotate, and the rotating worm wheel 433 drives the gear 434 to rotate through the support shaft, and the rotating gear 434 drives the support mechanism 41 to move upward through the rack 431, and the upwardly moving support 41 pushes the adsorption mechanism 44 to move out of the installation cavity 11, so that the adsorption mechanism 44 is adsorbed on the top wall of the shaft of the coal mine, thereby realizing the temporary suspension of the drone body 10 to extend the flight time of the drone body 10 to meet the inspection work under the coal mine.

[0059] In one embodiment of the present application, Figure 4 As shown, the support mechanism 41 may include a sleeve rod 411 , a slide rod 412 and a compression spring 413 .

[0060] The sleeve rod 411 is movably disposed in the mounting cavity 11, the slide rod 412 is slidably disposed in the sleeve rod 411, and the top of the slide rod 412 is respectively connected to a plurality of adsorption mechanisms 44 through the universal ball. That is, the top of the slide rod 412 is fixedly connected to the body of the universal ball, and the plurality of adsorption mechanisms 44 are fixedly connected to the rolling ball of the universal ball.

[0061] The compression spring 413 is disposed in the sleeve rod 411 , and one end of the compression spring 413 is connected to the bottom wall of the inner cavity of the sleeve rod 411 , and the other end of the compression spring 413 is connected to the bottom wall of the sliding rod 412 .

[0062] It can be understood that when the rack 431 drives the sleeve rod 411 to move upward, the sleeve rod 411 pushes the slide rod 412 upward through the compression spring 413, and the upward slide rod 412 pushes the adsorption mechanism 44 upward to adsorb and temporarily fix the drone body 10 on the top wall of the coal mine.

[0063] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 4 As shown, the adsorption mechanism 44 may include a connecting rod 441 , a rotating ball head 442 and a suction cup 443 .

[0064] Among them, one end of the connecting rod 441 is connected to the top of the sliding rod 412 through the universal ball, and the other end of the connecting rod 441 is connected to the rotating ball head 442. That is, one end of the connecting rod 441 is connected to the rolling ball of the universal ball.

[0065] The suction cup 443 is connected to the rotating ball head 442 via a connecting rod (not specifically marked in the figure).

[0066] Specifically, when the adsorption mechanism 44 extends above the drone body 10, as the drone body 10 flies upward, the suction cup 443 in the adsorption mechanism 44 is subjected to pressure and adsorbed on the top wall of the coal mine. Thus, the drone body can be suspended and stay on the top wall of the coal mine, thereby extending the flight time of the drone body 10 to meet the inspection work in the coal mine.

[0067] In addition, if the top wall of the coal mine is a non-planar wall, after the suction cup 443 is subjected to pressure, the rotating ball head 442 is pressed to drive the suction cup 443 to rotate through the connecting rod, so that the suction cup 443 is fully in contact with the non-planar wall. At the same time, the universal ball can also rotate after being subjected to force, and the suction angle of the suction cup 443 is adjusted, so that the suction cup is fully adsorbed on the non-planar wall.

[0068] As a possible situation, a gas detector (not shown in the figure) can also be set on the drone body 10, and the gas detector is electrically connected to the drone body 10, and the gas detector is wirelessly connected to the host computer through a signal receiver.

[0069] Specifically, when a gas leak occurs in a coal mine, the gas detector can detect the gas to determine the location of the gas leak, and send the detected gas concentration data to the host computer through a signal receiver, so that the staff can understand the concentration of the leaked gas and the location of the leak in the coal mine, and perform precise maintenance on it to prevent explosions in the coal mine due to excessive gas leakage.

[0070] In summary, the explosion-proof drone of the embodiment of the present application can not only extend the flight time by hovering to meet the inspection work in the coal mine, but also can autonomously avoid obstacles to prevent the drone from being damaged by collision, thereby reducing the cost of use.
