Description

Technical Field

[0001] This utility model relates to the field of inspection drone technology, specifically a drone inspection gimbal protection device. Background Technology

[0002] A drone gimbal is a stable platform mounted on the bottom of a drone, used to carry cameras, sensors, and other equipment. An inspection gimbal protection device is specifically designed to protect the gimbal from external threats in the inspection environment, such as collisions, dust, and rain, ensuring that the gimbal is not easily damaged under complex working conditions.

[0003] Chinese patent provides an inspection drone with a gimbal, publication number CN210212804U, which includes a drone body and a data acquisition device installed on the drone body. The data acquisition device includes a base plate installed at the bottom of the drone body and a support plate horizontally installed at the bottom of the base plate.

[0004] The aforementioned device, by setting up a protective mechanism, not only improves the anti-collision performance of the drone, but also enhances the stability and safety of the camera equipment on the drone during operation. When the drone collides, the protective mechanism can also effectively protect the camera equipment, preventing it from falling and reducing the usage and maintenance costs of the drone.

[0005] However, its structure is relatively simple. Since the gimbal is installed at the bottom of the drone, when the drone lands, the bottom will contact the landing platform first, which will generate a large impact force. This impact force is directly transmitted to the gimbal without reduction, which may damage the electronic components installed on it. In addition, when the drone lands unexpectedly, the drone's protective plate is easily damaged. It may fold inward, but since it is fitted around the outer ring of the gimbal and its position is fixed, folding it can easily cause significant squeezing damage to the gimbal. Utility Model Content

[0006] The purpose of this utility model is to provide a protective device for the gimbal of a drone inspection, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A protective device for a drone inspection gimbal includes a protective component disposed at the bottom end of the drone's suspension frame. The protective component has a movable rod and a buffer plate. A connecting screw that is adaptively matched to the movable rod is fixedly connected to the bottom end of the drone's suspension frame, and the movable rod is threadedly installed at the bottom end of the connecting screw.

[0009] The bottom end of the movable rod is fixedly installed with the inspection gimbal body. The buffer plate is slidably installed on the upper part of the outer ring of the movable rod. A buffer spring is provided at the top of the buffer plate and around the outer ring of the movable rod. The upper part of the outer ring of the movable rod is provided with an external thread, and the movable rod is connected to two adjusting nuts through the external thread. The two adjusting nuts are respectively located above the buffer spring and below the buffer plate. A pressure plate is provided at the connection between the adjusting nut above the buffer plate and the buffer spring. Movable plates are movably installed on both sides of the buffer plate. Buffer columns are threadedly connected to the bottom corners of the bottom of the movable plates. Support columns are slidably installed at the bottom ends of the buffer columns.

[0010] Preferably, a vibration-absorbing rubber sleeve is adhered to the outer ring of the buffer column near the top of the support column, and the bottom end of the vibration-absorbing rubber sleeve abuts against the top end of the support column.

[0011] Preferably, two support columns on the same side are grouped together, and a reinforcing frame is installed on the lower outer ring of each group of support columns, and the reinforcing frame is made of a transparent plate.

[0012] Preferably, the bottom end of the movable plate is detachably equipped with side protective plates at both the front and rear ends via mounting bolts, and the side protective plates are made of aviation aluminum honeycomb panels.

[0013] Preferably, an electric telescopic rod is installed at the top of the buffer plate near both sides, and the push rod end of the electric telescopic rod is connected to the movable plate through a connecting block.

[0014] Preferably, the support column and the inspection gimbal body are not on the same straight line, and there is a sufficient gap between the side protective plate and the inspection gimbal body.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model uses an adjusting nut, a buffer spring, and a buffer plate to work together. Because multiple support columns and buffer columns are installed around the inspection gimbal body, when the inspection drone falls, the impact force can be buffered, preventing the impact force from being directly transmitted to the inspection gimbal body. This reduces the probability of damage to the electronic components inside the inspection gimbal body and helps to improve the service life of the inspection gimbal body.

[0017] By setting up side protective plates, reinforcement frames, and inspection gimbals in coordination, when a drone falls due to an accidental collision, the movable plates, side protective plates, and reinforcement frames on its sides and below can push it away when damaged, reducing the probability of it directly contacting the inspection gimbal. At the same time, the side protective plates will undergo controllable plastic deformation to absorb the impact force during the fall, thus facilitating the protection of the inspection gimbal.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Combination Figures 1-3 A protective device for a drone inspection gimbal includes a protective component 2 installed at the bottom of a drone suspension frame 1. The protective component 2 has a movable rod 4 and a buffer plate 5. A connecting screw 3 that is compatible with the movable rod 4 is fixedly connected to the bottom of the drone suspension frame 1, and the movable rod 4 is threadedly installed at the bottom of the connecting screw 3.

[0025] See Figure 2Furthermore, the bottom end of the movable rod 4 is fixedly installed with the inspection gimbal body 7, the buffer plate 5 is slidably installed on the upper part of the outer ring of the movable rod 4, the top of the buffer plate 5 and the outer ring of the movable rod 4 are provided with a buffer spring 9, the upper part of the outer ring of the movable rod 4 is provided with an external thread, and the movable rod 4 is connected to two adjusting nuts 8 through the external thread, and the two adjusting nuts 8 are respectively located above the buffer spring 9 and below the buffer plate 5, and a pressure plate is provided at the connection between the adjusting nut 8 above the buffer plate 5 and the buffer spring 9. Movable plates 6 are movably installed on both sides of the buffer plate 5, and buffer columns 10 are threadedly connected to the bottom corner of the movable plate 6. A support column 11 is slidably installed at the bottom of the buffer column 10, and a vibration-absorbing rubber sleeve 12 is adhered to the outer ring of the buffer column 10 near the top of the support column 11, and the bottom end of the vibration-absorbing rubber sleeve 12 abuts against the top end of the support column 11.

[0026] Specifically, when the drone lands normally, the impact force generated by the support column 11 contacting the ground first is transmitted to the support column 11. As the support column 11 slides upward, it will compress the vibration-absorbing rubber sleeve 12. The vibration-absorbing rubber sleeve 12 can initially buffer the impact force. Then the impact force is continuously transmitted to the buffer plate 5. Subsequently, the timely and effective deformation of the buffer spring 9 can buffer the impact force a second time. Only then will the minor vibration be transmitted to the drone suspension frame 1 and then to the inspection gimbal body 7, so as to reduce the damage to the inspection gimbal body 7, reduce the probability of damage to the internal components of the inspection gimbal body 7, and improve the service life of the inspection gimbal body 7.

[0027] Example 2

[0028] See Figure 2 and Figure 3 Furthermore, based on Embodiment 1, it is further found that two support columns 11 on the same side form a group, and a reinforcing frame 14 is installed on the lower outer ring of each group of support columns 11. The reinforcing frame 14 is a transparent plate. Side protective plates 13 are detachably installed on the bottom end of the movable plate 6 at both the front and rear ends by mounting bolts. The side protective plates 13 are made of aviation aluminum honeycomb panels. Electric telescopic rods 15 are installed on the top of the buffer plate 5 at both sides. The push rod end of the electric telescopic rod 15 is connected to the movable plate 6 through a connecting block. The support columns 11 and the inspection gimbal body 7 are not on the same straight line, and there is a sufficient gap between the side protective plates 13 and the inspection gimbal body 7.

[0029] Specifically, when the inspection drone crashes unexpectedly, the push rod of the electric telescopic rod 15 will extend to push multiple support columns 11 away from the inspection gimbal body 7. When it deforms upon impact, the reinforcement frame 14 can reinforce it to limit the degree of deformation at the bottom, preventing it from easily contacting the inspection gimbal body 7 and reducing the probability of damage to the inspection gimbal body 7. In addition, the side protective plate 13 is made of honeycomb mesh, which will undergo controllable plastic deformation when it is impacted, so as to absorb the impact force during the fall and further reduce the probability of damage to the inspection gimbal body 7. Furthermore, the side protective plate 13 needs to be replaced after a single use to prevent structural damage and loss of protective function.

[0030] In actual operation, when the drone lands normally, the impact force generated by the support column 11 contacting the ground first will be transmitted to the support column 11. As the support column 11 slides upward, it will squeeze the vibration-absorbing rubber sleeve 12. The vibration-absorbing rubber sleeve 12 can buffer the impact force initially. Then the impact force is continuously transmitted to the buffer plate 5. Subsequently, the timely and effective deformation of the buffer spring 9 can buffer the impact force a second time. Only then will the small vibration be transmitted to the drone suspension frame 1 and then to the inspection gimbal body 7, so as to reduce the damage to the inspection gimbal body 7, reduce the probability of damage to the internal components of the inspection gimbal body 7, and improve the service life of the inspection gimbal body 7.

[0031] When the inspection drone crashes due to an accident, the push rod of the electric telescopic rod 15 will extend to push multiple support columns 11 away from the inspection gimbal body 7. When it falls and deforms, the reinforcement frame 14 can be used to reinforce it to limit the degree of deformation at the bottom, so that it will not easily come into contact with the inspection gimbal body 7, thereby reducing the probability of damage to the inspection gimbal body 7.

[0032] Furthermore, the side protective plate 13 is made of honeycomb mesh, which will undergo controllable plastic deformation when it is impacted, so as to absorb the impact force when falling and further reduce the probability of damage to the inspection gimbal body 7. In addition, the side protective plate 13 needs to be replaced after a single use to prevent its structure from being damaged and losing its protective function.

[0033] Furthermore, the display and control components and modules used in the aforementioned electric telescopic pole 15 and inspection pan-tilt body 7 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
