Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) equipment technology, specifically relating to a dustproof device for UAVs used in coal shed scenarios and a UAV used in coal shed scenarios. Background Technology

[0002] In coal storage management within the railway transportation sector, real-time monitoring of the inventory capacity of multiple coal sheds is crucial for developing efficient transportation plans. Currently, the industry commonly uses fixed laser measuring devices (such as laser coal inventory meters) for inventory monitoring. These devices require permanent installation on the top or side walls of each coal shed, leading to a significant increase in equipment procurement, installation, and maintenance costs in multi-coal-shed scenarios.

[0003] To reduce equipment procurement, installation, and maintenance costs, a dynamic monitoring method is proposed, employing an indoor drone equipped with a data acquisition module (laser and vision sensors). This leverages the convenience of laser measurement and the mobility of drones. It supports continuous cross-regional operation across multiple coal sheds, saving procurement costs compared to traditional fixed equipment and reducing maintenance expenses, thus achieving safe, accurate, and low-cost intelligent coal inventory management.

[0004] However, the harsh environment inside the coal shed, with dust concentrations as high as 200-500 mg / m³, poses a serious threat to the reliable operation of drones. To protect the laser measurement device and vision sensor, a hemispherical transparent dust cover is usually installed. This covers the laser measurement device and vision sensor, ensuring that the field of view is not affected while protecting the laser measurement device and vision sensor.

[0005] However, dust easily adheres to the transparent dust cover. Once the dust accumulates to a certain thickness, the accuracy of the measurement data decreases significantly, requiring frequent shutdowns for manual wiping, which greatly reduces the efficiency of mobile measurement by the drone.

[0006] Current technology typically involves installing scrapers on drones, which are then driven by a drive mechanism to intermittently and reciprocate, scraping away dust from the surface of the transparent dust cover. This addresses the need for frequent shutdowns for manual wiping. However, the dust concentration inside coal sheds is high, and the dust buildup on the surface of the transparent dust cover is rapid. Scraping alone is insufficient to thoroughly clean the surface, resulting in poor cleaning and potentially producing a smearing-like effect. Utility Model Content

[0042] Please refer to the following: Figures 1 to 3 The present invention provides a dustproof device for drones used in coal shed scenarios and describes the drones used in coal shed scenarios.

[0043] The dustproof device for a drone used in a coal shed setting includes a transparent dust cover 10, an arc-shaped scraper, an air pump 30, and a drive assembly. The transparent dust cover 10 has a hemispherical structure and is fixedly connected to the drone's shell 50. The arc-shaped scraper is fitted to the transparent dust cover 10 and has rotating shafts 211 at both ends, which are used to rotatably connect to the drone's shell 50. The arc-shaped scraper has a ventilation chamber inside and several blowing holes 213 on its side, which face the transparent dust cover 10. The air pump 30 is fixed to the drone, and its air outlet is connected to the ventilation chamber through a connecting pipe 31. The drive assembly is fixed to the drone, and its power output end is connected to the rotating shafts 211 to drive the arc-shaped scraper to reciprocate along the surface of the transparent dust cover 10, blowing and scraping the surface of the transparent dust cover 10.

[0044] During operation, the blow hole 213 blows onto the surface of the transparent dust cover 10 on the front side of the arc-shaped scraper's movement direction.

[0045] It should be noted that the air pump 30 is connected to the drone by adhesive bonding or by screw tightening, and can be located on the outside or inside of the drone shell 50. Preferably, in this embodiment, the air pump 30 is located inside the drone shell 50 to protect the air pump 30, and a filter is installed at the air inlet of the air pump 30 to filter dust in the air to ensure cleaning efficiency.

[0046] The fewer the number of blow holes 213, the larger the width of the blow holes 213 in the circumferential direction of the arc-shaped scraper, and vice versa, so as to be able to completely blow the surface of the dust cover.

[0047] The beneficial effects of the drone dustproof device for coal shed scenarios provided in this utility model embodiment are as follows: Compared with the prior art, the drone dustproof device for coal shed scenarios provided in this utility model embodiment covers the outside of the data acquisition module with a transparent dustproof cover 10 to isolate dust; and drives an arc-shaped scraper to scrape the dust on the surface of the transparent dustproof cover 10 through a drive component; furthermore, the arc-shaped scraper has a ventilation cavity inside and several air jet holes on the side. When the arc-shaped scraper moves along the surface of the transparent dustproof cover 10 and scrapes the dust on the surface of the dustproof cover, the air jet holes first blow away most of the upper dust, leaving only the relatively firmly adhered bottom dust. Then, the surface is scraped by the arc-shaped scraper, thereby effectively improving the cleaning effect.

[0048] like Figure 3 As shown, in a specific embodiment of the dustproof device for a drone used in a coal shed scenario provided in this utility model, the arc-shaped scraper is provided with a plurality of spray holes 213 on both sides perpendicular to the rotation direction.

[0049] It should be noted that blow holes 213 are opened on both sides of the arc-shaped scraper perpendicular to the direction of rotation. On the one hand, the front side of the arc-shaped scraper can be blown during the back-and-forth movement of the arc-shaped scraper. On the other hand, the blow holes 213 located behind the direction of movement of the arc-shaped scraper can spray the surface of the dust cover a second time, further improving the cleaning effect. At the same time, an air film is formed on the surface of the dust cover, which effectively delays the adsorption of dust on the dust cover. This can extend the scraping interval, reduce the scraping frequency, and reduce the impact of the scraping operation on the data collection operation.

[0050] like Figure 3 As shown in the embodiment of the dustproof device for a drone in a coal shed scenario provided in this utility model, the arc-shaped scraper has inclined surfaces on both sides perpendicular to the rotation direction facing the transparent dustproof cover 10, and the blowing hole 213 is opened on the inclined surface so that the direction of the blowing hole 213 faces the dustproof cover.

[0051] like Figure 3As shown in the embodiment of the dustproof device for a drone in a coal shed scenario provided by this utility model, the arc-shaped scraper includes a support plate 21 and an elastic scraper 22. The elastic scraper 22 is disposed on the side of the support plate 21 facing the transparent dust cover 10 and is indirectly or directly connected to the support plate 21. The support plate 21 is arc-shaped and has the rotating shaft 211 at both ends. The ventilation cavity is provided inside the support plate 21.

[0052] Specifically, the support plate 21 is a rigid plastic plate or metal plate with a certain degree of rigidity, used to provide good support; the elastic scraper 22 is a soft and elastic curved plate such as rubber plate or silicone plate, used to better fit the dust cover, while avoiding scratching the dust cover.

[0053] Furthermore, such as Figure 3 As shown in the embodiment of the dustproof device for a drone in a coal shed scenario provided in this utility model, the elastic scraper 22 is provided with at least one arc-shaped groove 221 at axial intervals on the side facing the transparent dust cover 10, and the arc-shaped groove 221 extends circumferentially along the elastic scraper 22.

[0054] Specifically, the elastic scraper 22 is provided with two arc-shaped grooves 221, and the arc-shaped grooves 221 extend to both ends of the elastic scraper 22 to form a triple scraping during operation, which effectively improves the scraping effect.

[0055] Furthermore, such as Figure 3 As shown in a specific embodiment of the dustproof device for a drone in a coal shed scenario provided in this utility model, the arc-shaped scraper further includes a bladder 23, which is sandwiched between the elastic scraper 22 and the support plate 21 and connected to the support plate 21. The elastic scraper 22 is indirectly connected to the support plate 21 through the bladder 23, and the bladder 23 is in communication with the ventilation cavity.

[0056] Specifically, the bladder 23 is supported by an elastic material and adheres to the support plate 21 under normal pressure. The two sides of the bladder 23 are fixedly connected to the support plate 21 and the elastic scraper 22 by adhesive bonding or vulcanization. The support plate 21 has a connecting hole on the side facing the bladder 23, which connects to the bladder 23 and the ventilation chamber. During operation, the air pump 30 blows gas with a certain pressure into the ventilation chamber. Some of the gas enters the bladder 23 through the connecting hole, which increases the pressure inside the bladder 23, causing it to inflate and apply pressure to the elastic scraper 22. This creates a certain pressure between the elastic scraper 22 and the dust cover, ensuring the scraping effect.

[0057] like Figure 1 and Figure 3As shown in the embodiment of the dustproof device for a drone used in a coal shed scenario provided in this utility model, an air inlet channel is provided on the rotating shaft 211 at one end of the arc-shaped scraper, and the connecting pipe 31 is connected to and communicates with the air inlet channel.

[0058] It should be noted that the connecting pipe 31 is a flexible pipe and is fixedly connected to the rotating shaft 211 which has an air inlet channel;

[0059] In another embodiment, the connecting pipe 31 is a rigid pipe, in which case the connecting pipe 31 is rotatably sealed with the rotating shaft 211 which has an air inlet channel.

[0060] like Figure 2 and Figure 3 As shown in the embodiment of the dustproof device for a drone in a coal shed scenario provided by this utility model, a gear 212 is fixed on the rotating shaft 211 at one end of the arc-shaped scraper, and the gear 212 is connected to the power output end of the drive component.

[0061] It should be noted that gear 212 is welded to shaft 211, or fixedly connected to shaft 211 via locating pins and keys. Installing gear 212 on shaft 211 facilitates the transmission connection between shaft 211 and the drive assembly.

[0062] Furthermore, such as Figure 1 As shown in the embodiment of the dustproof device for a drone in a coal shed scenario provided by this utility model, the drive assembly includes a rack 41 and a drive element 42. The rack 41 is disposed on one side of the gear 212 and meshes with the gear 212. The drive element 42 is connected to the power output end of the rack 41 to drive the rack 41 to reciprocate.

[0063] It should be noted that the drive element 42 is a cylinder, and the rack 41 is fixedly connected to the piston rod of the cylinder. In addition, the drive element 42 can also be a hydraulic cylinder, electric actuator, or other device that can drive the rack 41 to reciprocate in a certain direction.

[0064] like Figure 1 and Figure 2 As shown, based on the same inventive concept, this utility model embodiment provides a drone for a coal shed scenario, including the above-mentioned drone dustproof device for a coal shed scenario.

[0065] It should be noted that the drone integrates existing laser measurement devices and vision sensors, and the laser measurement devices and vision sensors are covered by a dust cover.

[0066] The beneficial effects of the drone for coal shed scenarios provided in this utility model embodiment are as follows: Compared with the prior art, the drone for coal shed scenarios provided in this utility model embodiment is equipped with the above-mentioned dustproof device. When cleaning the dust on the surface of the dustproof cover, the jet nozzle first blows away most of the upper dust, leaving only the firmly adhered bottom dust. Then, the surface is scraped by the arc-shaped scraper, thereby effectively improving the cleaning effect.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
