Abstract
Description
Technical Field
[0001] This utility model relates to the field of inspection drone technology, and in particular to a protective structure for an inspection drone inside a furnace. Background Technology
[0002] The furnace is a core component of combustion or heating equipment, such as industrial furnaces, boilers, and burners. Regular inspections of the furnace can help identify potential problems, damage, or abnormalities in a timely manner, allowing for appropriate repair and maintenance measures to avoid possible malfunctions or dangers.
[0003] The existing technology includes a base, on which four mounting seats are fixedly connected to the outer surface. Each of the four mounting seats, located away from the base, is equipped with a drive blade. Each of the four drive blades has a protective component on its outer surface. The drive blade drives the cleaning brush to rotate via a transmission component, thereby cleaning the protective net on the upper part of the protective frame. This ensures that the protective net is cleaner during use and increases the practicality of the device.
[0004] The existing technology also has the following drawbacks: When the inspection drone flies inside the furnace, the blades are protected by the protective net of the protective frame to prevent them from being affected by dust and debris inside the furnace. However, after the inspection inside the furnace is completed, the blades need to be maintained regularly after long-term operation. The protective components cover the blades, which increases the difficulty of maintenance and the overall service life of the device is relatively short. Utility Model Content

[0029] Example 1
[0030] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a protective structure for a furnace inspection drone, capable of retracting and extending the protective frame 206 to meet the needs at different times. It includes:
[0031] The main unit 100 includes a frame body 101, with four connecting frames 102 fixedly installed at the four ends of the frame body 101. The main unit 100 also includes a flight component 103 for the flight power output of the frame body 101.
[0032] The protection unit 200 includes a protection section and an adjustment section. The protection section is located at the four ends of the adjustment section. The protection section is used to protect the UAV during flight, and the adjustment section is used to control the position of the protection section to meet the needs at different times.
[0033] The support unit 300 includes a support section and a power section. The power section is located on the top surface of the support section and is used to adjust and control the support section. The support section is used to support the placement of the frame body 101.
[0034] In use, the main unit 100 can be moved into the furnace through the flight component 103 to quickly inspect the inside of the furnace. The flight component 103 is effectively protected by the protective unit 300. After the inspection is completed, the flight component 103 is moved out of the furnace and the main unit 100 is moved and stabilized by the support unit 300. The position of the protective unit 300 is adjusted to maintain the flight component 103.
[0035] Example 2
[0036] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the adjustment part includes two bidirectional hydraulic cylinders A201 fixed on the upper and lower end faces of the frame body 101. Fixed rods 202 are fixedly provided on the outer side of the output rods at both ends of the bidirectional hydraulic cylinders A201. Two sliders 203 are slidably connected to the front and rear end surfaces of the fixed rods 202 respectively. A stop 204 is hinged to the inner wall of the slider 203.
[0037] Specifically, the protective part includes a slide rod 208 fixedly connected to the inner wall of the connecting frame 102. A bidirectional hydraulic cylinder B205 is slidably connected to the surface of the slide rod 208. The side of the bidirectional hydraulic cylinder B205 is slidably connected to the inner wall of the connecting frame 102. The inner side of the bidirectional hydraulic cylinder B205 is fixedly connected to the outer side of the abutment 204. A protective frame 206 is fixedly installed on the upper and lower end faces of the output rod of the bidirectional hydraulic cylinder B205. A protective net 207 is fixedly installed on the inner wall of the protective frame 206.
[0038] In addition, the flight assembly 103 includes a dual-axis motor 1031, and the inner walls of four connecting frames 102 are fixedly connected to the upper and lower end faces of the four dual-axis motors 1031 respectively. Flight blades 1032 are fixedly sleeved on the surfaces of the two output rods of the dual-axis motors 1031. There are four flight blades 1032, and the shape of the flight blades 1032 is a slender leaf shape.
[0039] In use, the dual-axis motor 1031 is started, causing the two flight blades 1032 to rotate, thereby driving the frame body 101 connected by the connecting frame 102 to fly. The bidirectional hydraulic cylinder B205 is started, causing the protective frame 206 to move up and down without hitting the flight blades 1032. Then, the bidirectional hydraulic cylinder A201 is started, causing the fixed rod 202 to move outward. Through the sliding of the slider 203 on the surface of the fixed rod 202 and the hinge between the slider 203 and the abutment 204, the protective frame 206 moves to the vertical position of the flight blades 1032. The bidirectional hydraulic cylinder B205 is started again to retract it to protect the flight blades 1032 from flight. The protective net 207 does not affect airflow.
[0040] The power unit includes a motor 301 fixedly connected to the bottom surface of the frame body 101. A main gear 302 is fixedly sleeved on the surface of the output rod of the motor 301. Two driven gears 305 are respectively meshed on the left and right end faces of the main gear 302. A rotating rod 304 is fixedly installed on the inner wall of the driven gear 305.
[0041] In addition, the support includes two fixed cylinders 303 fixedly connected to the bottom surfaces of the left and right ends of the frame body 101. The inner wall of the fixed cylinder 303 is rotatably connected to the surface of the rotating rod 304. Two support frames 306 are fixedly sleeved on the surfaces of the two rotating rods 304 respectively. The two support frames 306 are composed of a frame and a protective pad at the bottom. The two protective pads are made of silicone soft pads and are used to cushion the frame body 101 when it lands.
[0042] When in use, if it is necessary to move the main frame 101 outside the furnace, start the motor 301 to make the main gear 302 rotate. Through the meshing transmission of the main gear 302 and two driven gears 305, the two rotating rods 304 rotate in opposite directions synchronously, so that the two support frames 306 are raised, and the main frame 101 is quickly brought to a stop on the ground for maintenance.
[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
