Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicle accessories, and in particular relates to a data acquisition device for unmanned aerial vehicle inspection. Background Art

[0002] At present, the method of using drones with cameras to collect data is widely used in geological environment, factory safety, modular equipment and other fields. Using drones to conduct inspections and collect image information of target areas can improve inspection efficiency and reduce manpower consumption.

[0003] Currently, when drones are collecting target objects, their cameras are often directly exposed to the environment. Although the camera itself has a lens glass plate to shield the internal electronic components, the external environment, such as high humidity and impurities, can easily cause water mist, dust and impurities to adhere to the glass plate, resulting in unclear collected image information. Frequent round trips to the take-off and landing points for manual cleaning and maintenance are required, which reduces the continuity and convenience of data collection. Summary of the invention

[0004] The purpose of the present invention is to provide a data acquisition device for unmanned aerial vehicle inspection to solve the problems mentioned in the background technology.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is as follows:

[0006] A data collection device for unmanned aerial vehicle inspection, comprising a body, landing gears are arranged on the left and right sides of the lower end of the body, a collection camera is arranged in the middle of the lower end of the unmanned aerial vehicle, and a protective mechanism matching the collection camera is also arranged at the lower end of the body;

[0007] The protection mechanism includes a protective ball cover, a transmission assembly and a cleaning assembly. The protective ball cover is rotatably arranged at the lower end of the machine body and is in a hemispherical structure as a whole. The transmission assembly is arranged at the machine body and connected and matched with the protective ball cover. The cleaning assembly is arranged at the lower end of the machine body and matched with the protective ball cover.

[0008] The cleaning assembly includes a scraper bar, an arc bar, a cleaning bar and a tractor. The scraper bar is fixed to the machine body and extends downward in a spiral structure as a whole to fit the surface of the protective ball cover. The arc bar is elastically slidably arranged on the machine body and is concentric with the protective ball cover. The cleaning bar is elastically slidably arranged on one end of the arc bar toward the protective ball cover and abuts and matches with the scraper bar. The tractor is arranged between the protective ball cover and the arc bar.

[0009] The transmission assembly includes a gear ring, a fixed ring, a motor and a gear. The fixed ring is rotationally connected to the protective ball cover and is fixedly connected to the body. The gear ring is arranged at the largest diameter of the inner side of the protective ball cover. The motor is embedded in the body. The gear is transmission-connected to the output shaft of the motor and meshes with the gear ring.

[0010] The traction device includes a magnetic ring, an adsorption sheet and an elastic reset member. The magnetic ring is embedded in the inner side of the protective ball cover and constitutes a protective ball cover. The adsorption sheet is fixed on the upper side of the arc bar toward one end of the protective ball cover and matches the horizontal height of the magnetic ring. The elastic reset member is arranged on the outer side of the fixed ring and connected to the arc bar. In the initial state, the arc bar is affected by the elastic reset member to keep moving toward the side with a higher horizontal height of the scraper bar.

[0011] The lower end level of the arc strip is lower than the lower end level of the arc strip.

[0012] The protective ball cover is made of a transparent material, the scraper strip is a silicone scraper strip and is pasted with absorbent cotton at the rear end of the lower end relative to the spiral line.

[0013] The cleaning component and the transmission component are both located at the non-image acquisition end of the acquisition camera.

[0014] Compared with the prior art, the present invention has at least the following advantages:

[0015] Through the setting of a protective mechanism, the present application can provide more effective protection for the collection camera when the drone collects image information of the target point. At the same time, during the collection process, without hindering the collection camera from collecting image information, the surface of the protective ball cover can be automatically cleaned to further improve the collected image effect. The cleaning component itself can also perform self-cleaning to avoid secondary adhesion of some impurities and dirt. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-4 As shown, a data acquisition device for unmanned aerial vehicle inspection includes a body 1, a landing gear 11 is provided on the left and right sides of the lower end of the body 1, a collection camera 12 is provided in the middle of the lower end of the unmanned aerial vehicle, and a protective mechanism matching the collection camera 12 is also provided at the lower end of the body 1;

[0024] The protection mechanism includes a protective ball cover 2, a transmission component and a cleaning component. The protective ball cover 2 is rotatably arranged at the lower end of the machine body 1 and is in a hemispherical structure as a whole. The transmission component is arranged at the machine body 1 and connected and matched with the protective ball cover 2. The cleaning component is arranged at the lower end of the machine body 1 and matches with the protective ball cover 2.

[0025] The cleaning assembly includes a scraper strip 3, an arc strip 31, a cleaning strip 32 and a tractor. The scraper strip 3 is fixedly arranged on the body 1 and extends downward in a spiral structure as a whole to fit the surface of the protective ball cover 2. The arc strip 31 is elastically slidably arranged on the body 1 and is concentric with the protective ball cover 2. The cleaning strip 32 is elastically slidably arranged on one end of the arc strip 31 toward the protective ball cover 2 and abuts against the scraper strip 3. The tractor is arranged between the protective ball cover 2 and the arc strip 31.

[0026] When collecting images during the inspection process of the drone, the collection camera 12 is used to capture the image information of the current environment, and the protective ball cover 2 is used to provide protection for the collection environment of the collection camera 12 to prevent impurities, flying insects and other debris from affecting the collection camera 12 itself or the image collection area. Especially in an environment with high humidity and high particulate matter in the air, the condensed water vapor and impurities attached to the protective ball cover 2 will be actively rotated toward the scraper bar 3 under the action of the transmission component, and then the water vapor impurities on the protective ball cover 2 are scraped off by the scraper bar 3. At the same time, since the scraper bar 3 is a spiral structure as a whole, it will guide the impurities and water to move to the lower side of the protective ball cover 2, which is more conducive to the removal of such substances. At the same time, according to the rotation direction of the spiral line of the scraper bar 3, the direction in which the transmission component drives the protective ball cover 2 corresponds. Such a structure can provide environmental protection for the collection camera 12 when collecting image data outdoors, improve the clarity of the collected image, and at the same time, the protective ball cover 2 itself can act as a buffer, and can provide protection for the collection camera 12 when the drone crashes accidentally, so as to ensure that the collected data and the collection module can be retained.

[0027] The transmission assembly includes a gear ring 33, a fixed ring 34, a motor and a gear 35. The fixed ring 34 is rotationally connected to the protective ball cover 2 and is fixedly connected to the body 1. The gear ring 33 is arranged at the largest diameter of the inner side of the protective ball cover 2, and the motor is embedded in the body 1. The gear 35 is transmission-connected to the output shaft of the motor and meshes with the gear ring 33. When driving the protective ball cover 2, the motor starts and uses the gear 35 to drive the gear ring 33 to rotate, and the gear ring 33 produces a rotational effect on the protective ball cover 2. The fixed ring 34 is used to further provide connection stability for the protective ball cover 2.

[0028] The traction device includes a magnetic ring 4, an adsorption sheet 41 and an elastic reset piece. The magnetic ring 4 is embedded in the inner side of the protective ball cover 2 and constitutes a protection for the protective ball cover 2. The adsorption sheet 41 is fixed on the upper side of the arc bar 31 toward one end of the protective ball cover 2 and matches the horizontal height of the magnetic ring 4. The elastic reset piece is arranged on the outer side of the fixed ring 34 and is connected to the arc bar 31. In the initial state, the arc bar 31 is affected by the elastic reset piece to keep moving toward the side with a higher horizontal height of the scraper strip 3.

[0029] During the movement of the protective ball cover 2, the magnetic ring 4 will circulate through the cleaning component, and the adsorption sheet 41 provided on the arc bar 31 will be magnetically attracted and pulled when corresponding to the magnetic ring 4. At this time, the arc bar 31 will move synchronously with the magnetic ring 4. Since the cleaning strip 32 is elastically slidably provided on the arc bar 31 and abuts against the lower end of the scraper strip 3, the cleaning strip 32 will move downward during the synchronous movement of the arc bar 31 and clean the end of the scraper strip 3 moving toward the protective ball cover 2, thereby further removing impurities and water vapor removed from the protective ball cover 2, thereby improving the cleaning effect. The elastic reset member and the elastic sliding method between the cleaning strip 32 and the arc bar 31 can be reset by means of a spring or a spring sheet, and the horizontal projection end position of the further elastic reset member is shorter than the horizontal projection end position of the scraper strip 3, so as to avoid the cleaning strip 32 and the abutting end of the scraper strip 3 from being separated.

[0030] The lower end level of the arc bar 31 is lower than the lower end level of the arc bar 31 .

[0031] The protective ball cover 2 is made of transparent material, the scraper strip 3 is a silicone scraper strip 3 and absorbent cotton is pasted on the rear end of the lower end relative to its own spiral line; the transparent material can be acrylic or tempered glass, and the absorbent cotton can further absorb the residual water vapor. Of course, other components that can remove residual water vapor can also be used.

[0032] The cleaning component and the transmission component are both located at the non-image acquisition end of the acquisition camera 12 .

[0033] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
