Description

Technical Field

[0001] This utility model relates to the field of monitoring technology, and specifically to a monitoring device for use in a confined space. Background Technology

[0002] Limited spaces are typically used as enclosed or partially enclosed fixed workplaces. These spaces allow workers to enter and perform tasks, but the environment is complex and can easily lead to the accumulation of toxic, harmful, flammable, and explosive substances. Therefore, there is a certain degree of danger when workers enter. As a result, drone technology is being used to carry various monitoring devices to improve the safety of monitoring during technological development.

[0003] Drone monitoring equipment needs to move up, down, left, and right within a limited space to obtain a better monitoring perspective. Since the drone's rotor is usually located at the top of the drone, the upward movement of the drone monitoring equipment can cause the rotor to collide with the limited space, affecting the use of the drone.

[0004] Therefore, a monitor for confined spaces is proposed to solve the problem that the rotor may collide with the confined space during the upward movement of the drone monitoring equipment, thus affecting the use of the drone. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please refer to the following: Figure 1-3 The monitor shown is for use in confined spaces and includes an unmanned aerial vehicle (UAV) body 1, a main rotor 2, an arm 3, a support frame 4, and a monitoring device 5. The monitoring device 5 is actually a surveillance camera that transmits monitoring data in real time to detect areas within the confined space. A first groove 6 is formed on the arm 3, and a first motor is fixedly connected within the groove 6. The first motor drives an auxiliary rotor 7 to rotate, improving flight stability. The output end of the first motor is fixedly connected to the auxiliary rotor 7. A bracket 8 is fixedly connected to the arm 3, and a connecting frame 9 is fixedly connected to the bracket 8. A baffle 10 is fixedly connected to the upper end of the connecting frame 9. The height of the auxiliary rotor 7 and the baffle 10 is higher than that of the main rotor 2. Then, a connecting frame 9 and a buffer pad 11 are set on the outside of the auxiliary rotor 7 to increase the impact buffer and prevent the main rotor 2 and the auxiliary rotor 7 from being damaged by collision. The two connecting frames 9 are fixedly connected to the opposite side of the two connecting frames 9. The connecting frame 12 has a limit groove 13. A connecting rod 14 is inserted into the limit groove 13. Spring pins 15 are inserted on both sides of the connecting rod 14. The spring pins 15 contact the limit groove 13. By setting the connecting rod 14 and the spring pins 15, the protection surface on the upper side of the auxiliary rotor 7 can be increased and the stability can be improved.

[0022] The protective strip 17 is fixedly connected between two adjacent connecting sleeves 16. The protective strip 17 has a filamentous structure. The connecting sleeves 16 are fixedly connected to the connecting rod 14. By setting the protective strip 17, the anti-collision effect can be increased.

[0023] The connecting frame 9 has four parts, and the buffer pad 11 is fixedly connected to the outside of the connecting frame 9. The buffer pad 11 is made of rubber material. By setting the buffer pad 11, the anti-collision effect is increased.

[0024] The upper end of the connecting frame 9 is flush with the distance sensor 18, which is fixedly connected to the sleeve 12. By setting the distance sensor 18, distance warning can be provided to avoid or reduce collisions between the unmanned vehicle body 1 and the confined space when it moves upward.

[0025] The monitoring device 5 is fixedly connected to the connecting strip 20, the connecting strip 20 is fixedly connected to the output end of the third motor, the third motor is fixedly connected to one side of the rotating frame 19, the rotating frame 19 is fixedly connected to the output end of the second motor, and the second motor is fixedly connected to the bottom side of the drone body 1. By setting the second motor and the third motor, the monitoring device 5 can have the effect of rotation.

[0026] The support frame 4 is fixedly connected to the bottom side of the support frame 23. The support frame 23 is fixedly connected to both ends of the rotating rod 22. The rotating rod 22 is fixedly connected to both ends of the dual-head motor. The dual-head motor is fixedly connected to one side of the protrusion. The protrusion is located in the third groove. The third groove is located on one side of the drone body 1. The dual-head motor drives the rotating rod 22 and the support frame 23 to rotate, thereby causing the support frame 4 to rotate and avoiding the limitation of the viewing angle of the monitoring equipment 5.

[0027] The contact roller 26 is made of rubber and is rotatably connected in the fourth groove, which is located at the bottom of the support frame 4. By setting the contact roller 26, the landing cushioning of the unmanned aerial vehicle 1 can be increased.

[0028] The unmanned aerial vehicle body 1 has a second groove 21 on its bottom side. The second groove 21 is fixedly connected to the bottom side of the spring rod 25. The spring rod 25 is in contact with the upper side of the gear plate 24. The gear plate 24 is fixedly connected to the support frame 23. By setting the gear plate 24 in conjunction with the spring rod 25, the rotation angle of the support frame 4 can be limited.

[0029] The second groove 21 contacts the slider 27, which rotates and is embedded in the support frame 23. By setting the slider 27, the stability of the rotation of the support frame 23 is increased.

[0030] Working principle: When the UAV body 1 enters the confined space and moves upward, the main rotor 2 and auxiliary rotor 7 are started to rotate. At this time, the connecting frame 9, the baffle 10 and the buffer pad 11 provide protection. Then, with the help of the connecting rod 14 and the protective strip 17, the main rotor 2 and auxiliary rotor 7 can be prevented from contacting obstacles, reducing the instability of the monitoring equipment 5 during monitoring. Then, when the UAV body 1 is flying, the dual-head motor is started to drive the rotating rod 22 and the support frame 23 to rotate, so that the contact roller 26 is close to the arm 3, avoiding the limitation of the viewing angle of the monitoring equipment 5.

[0031] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0032] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.
