On the one hand, the traditional installation method is usually complicated, requiring the use of multiple tools and taking a long time, which seriously affects the deployment efficiency of the inspection work. On the other hand, when the equipment needs to be maintained or replaced, the disassembly process is also very cumbersome, which brings great trouble to the operator. Summary of the invention

[0005] The assembly device comprises a fixed shell, the inner wall of the fixed shell is slidably connected with a push plate, the outer wall of the push plate is fixedly connected with a slide rod, the outer side of the slide rod is slidably connected with a reset assembly, the outer side of the fixed shell is fixedly connected with a locking assembly, and the two sides of the fixed shell are rotatably connected with right-angle limit plates. The protective shell is inserted into the inner side of the fixed shell. During the insertion process, the protective shell pushes the push plate inside the fixed shell to move, and at this time the push plate contacts the right-angle limit plate and forces the right-angle limit plate to deflect;

[0006] The inspection device includes a protective shell, an electric push rod is fixedly connected to the top of the inner wall of the protective shell, the output end of the electric push rod is fixedly connected to a mobile frame, the inner side of the mobile frame is fixedly connected to an inspection probe, the outer side of the protective shell is rotatably connected to a flip cover plate, the outer wall of the flip cover plate is fixedly connected to a reset spring, the bottom end of the reset spring is fixedly connected to an arc guide rail, and both sides of the mobile frame are fixedly connected to elastic top plates, and the electric push rod is started, and the output end of the electric push rod pushes the mobile frame to slide inside the protective shell. The mobile frame drives the inspection probe to slide to the outside of the protective shell. In this process, the elastic top plate is first released from the flip cover plate, and the flip cover plate is pushed open, so that the reset spring is compressed along the outer side of the arc guide rail. At this time, the inspection probe can be used to inspect the power transmission and distribution lines.

[0007] Preferably, the top of the fixed shell is fixedly connected to the bottom of the aircraft body, the inner side of the fixed shell is slidably connected to the outer side of the protective shell, the right-angle limit plate is clamped with the two sides of the protective shell through a limit groove, and the limit groove is opened in the wall of the protective shell, and when the right-angle limit plate is clamped into the limit groove, the inspection device can be fixed.

[0008] Preferably, the bottom of the mobile frame is slidably connected to the bottom of the inner wall of the protective shell, the bottom of the arc-shaped guide rail is fixedly connected to the bottom of the protective shell, the inner wall of the flip cover is slidably connected to the outer wall of the arc-shaped guide rail, the outer side of the elastic top plate is in contact with the inner side of the flip cover, and when the flip cover is pushed open, the return spring is compressed along the outer side of the arc-shaped guide rail. The arc-shaped guide rail provides a stable guide for the compression of the return spring to prevent the return spring from being twisted or misplaced during the compression process. At the same time, the compression of the return spring stores energy, providing power for the subsequent automatic closing of the flip cover.

[0009] Preferably, the reset assembly includes a connecting plate, sliding rods are fixedly connected on both sides of the connecting plate, a top block is fixedly connected to one end of the sliding rod away from the connecting plate, and a tension spring is fixedly connected to the outer side of the connecting plate. During the deflection of the right-angle limit plate, the outer side of the right-angle limit plate contacts the top block in the reset assembly and forces the top block to push the connecting plate to the side away from the fixed shell through the sliding rod, and the tension spring is stretched at this time.

[0010] Preferably, the center of the connecting plate is slidably connected to the outer wall of the sliding rod, the outer wall of the sliding rod is slidably connected to the inner wall of the fixed shell, and the outer side of the fixed shell is fixedly connected to an end of the tension spring away from the connecting plate. When the inspection device needs to be removed, it is only necessary to pull the two sliding plates to both sides along the rectangular hole to make the two sliding plates move away from each other. At this time, the right-angle limit plate can be restored to its initial state under the action of the elastic force of the tension spring, and the push plate can be reset by the movement of the right-angle limit plate, thereby pushing the inspection device out of the fixed shell.

[0011] Preferably, the locking assembly includes a limit block, the inner wall of the limit block is slidably connected with an insertion rod, the outer wall of the insertion rod is fixedly connected with a sliding plate, the outer side of the sliding plate is fixedly connected with a compression spring, the outer wall of the insertion rod is plugged into the inner wall of the sliding rod through a plug hole, and the plug hole is opened in the wall of the sliding rod, and as the push plate moves, the sliding rod gradually slides to the outside of the fixed shell,

[0012] Preferably, the outer wall of the limit block is fixedly connected to the outer wall of the fixed shell, and the end of the compression spring away from the sliding plate is fixedly connected to the inner side of the limit block. The outer wall of the sliding plate is slidably connected to the inner wall of the connecting plate through a rectangular hole. During the sliding process of the sliding rod, when the insertion hole on its outer wall is aligned with the insertion rod in the locking assembly, under the action of the compression spring, the insertion rod slides out of the limit block and is inserted into the insertion hole, thereby locking the sliding rod, and then fixing the position of the push plate and the right-angle limit plate, preventing the right-angle limit plate from detaching from the limit groove during flight.

[0013] Preferably, the heat dissipation device includes a mounting plate, ventilation plates are fixedly connected to both sides of the mounting plate, a guide plate is fixedly connected to the outer side of the mounting plate, the top of the guide plate is rotatably connected to a rotating shaft, fan blades are fixedly connected to the outer side of the rotating shaft, and a heat dissipation plate is fixedly connected to the inner side of the mounting plate. During the flight of the aircraft body, the surrounding air enters the inner side of the heat dissipation device through the ventilation plates on the outer side of the mounting plate, and at this time, the airflow blows the fan blades to rotate along the rotating shaft under the guidance of the guide plate.

[0014] Preferably, the outer side of the mounting plate is fixedly connected to the inner side of the protective shell, the inner side of the protective shell is fixedly connected to the outer side of the ventilation plate, the outer side of the rotating shaft is rotatably connected to the center of the heat sink, and the fan blades rotate under the blowing of the airflow, further accelerating the flow speed of the air inside the heat sink.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention inserts the protective shell into the inner side of the fixed shell by setting an assembly device. During the insertion process, the protective shell pushes the push plate inside the fixed shell to move. At this time, the push plate contacts the right-angle limit plate and forces the right-angle limit plate to deflect, thereby causing the right-angle limit plate to be stuck in the limit groove. In this way, the inspection device can be fixed. The operation process is simple, which improves the convenience of installation.

[0017] 2. The present invention sets a locking assembly. As the push plate is displaced, the slide bar gradually slides toward the outside of the fixed shell. During the sliding process of the slide bar, when the insertion hole on its outer wall is aligned with the insertion rod in the locking assembly, under the action of the compression spring, the insertion rod slides out of the limit block and inserts into the insertion hole, thereby locking the slide bar, and then fixing the position of the push plate and the right-angle limit plate, preventing the right-angle limit plate from detaching from the limit groove during flight, reducing the possibility of accidents and improving the safety of inspection operations.

[0018] 3. The present invention sets a reset component. When the inspection device needs to be removed, it is only necessary to pull the two sliding plates to both sides along the rectangular holes to move the two sliding plates away from each other. At this time, the right-angle limit plate can be restored to its initial state under the elastic force of the tension spring. At the same time, the push plate can be reset by utilizing the movement of the right-angle limit plate, and then the inspection device can be pushed out of the fixed shell. This design makes the disassembly process simple and quick, without the need for complicated tools and cumbersome steps. The operator can easily push the inspection device out of the fixed shell, thereby improving the efficiency of equipment maintenance and replacement.

[0019] 4. The present invention provides a patrol device. When the flip cover is pushed open, the return spring is compressed along the outer side of the arc guide. The arc guide provides a stable guide for the compression of the return spring, preventing the return spring from being twisted or dislocated during the compression process. At the same time, the compression of the return spring stores energy, providing power for the subsequent automatic closing of the flip cover.

[0020] 5. The present invention sets a flip cover, and the electric push rod contracts to drive the movable frame to reset, so that the elastic top plate is separated from the flip cover. At this time, under the action of the reset spring, the flip cover rotates in the opposite direction and covers the opening of the protective shell again. This action can effectively protect the inspection probe and prevent it from being affected by external factors such as collision, dust, and moisture when it is not working, ensuring that it can work normally during the next inspection. At the same time, it can also prevent dust, debris, etc. from entering the inside of the protective shell.

[0021] 6. The present invention provides a heat sink. During the flight of the aircraft body, the surrounding air enters the heat sink through the ventilation plate outside the mounting plate. At this time, the airflow blows the fan blades along the rotating shaft under the guidance of the guide plate. The fan blades rotate under the blowing of the airflow, further accelerating the flow speed of the air inside the heat sink. The fast-flowing air can quickly take away the heat on the heat sink, improving the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The inner side is slidably connected to the outer side of the protective shell 31, the right-angle limit plate 24 is clamped with the two sides of the protective shell 31 through the limit groove 39, and the limit groove 39 is opened in the wall of the protective shell 31, the bottom of the movable frame 33 is slidably connected to the bottom of the inner wall of the protective shell 31, the bottom of the arc guide rail 36 is fixedly connected to the bottom of the protective shell 31, the inner wall of the flip cover plate 35 is slidably connected to the outer wall of the arc guide rail 36, and the outer side of the elastic top plate 38 contacts the inner side of the flip cover plate 35. When installing the inspection device 3, the protective shell 31 is inserted into the inner side of the fixed shell 21. During the insertion process, the protective shell 31 will push the push plate 22 inside the fixed shell 21 to move. At this time, the push plate 22 contacts the right-angle limit plate 24 and forces the right-angle limit plate 24 to deflect, thereby causing the right-angle limit plate 24 to be clamped in the limit groove 39, thereby fixing the inspection device 3, the operation process is simple, and the convenience of installation is improved;

[0038] When the inspection device 3 is in use, the electric push rod 32 is started, and the output end of the electric push rod 32 pushes the moving frame 33 to slide inside the protective shell 31. The moving frame 33 drives the inspection probe 34 to slide to the outside of the protective shell 31. During this process, the elastic top plate 38 is first released from the flip cover plate 35, and the flip cover plate 35 is pushed open, so that the reset spring 37 is compressed along the outside of the arc guide rail 36. At this time, the inspection probe 34 can be used to inspect the power transmission and distribution line; wherein, when the flip cover plate 35 is pushed open, the reset spring 37 is compressed along the outside of the arc guide rail 36. The arc guide rail 36 provides a stable guide for the compression of the reset spring 37, preventing the reset spring 37 from being twisted or dislocated during the compression process. At the same time, the compression of the reset spring 37 stores energy, providing power for the subsequent automatic closing of the flip cover 35. When the inspection is completed, the electric push rod 32 contracts, driving the movable frame 33 to reset, so that the elastic top plate 38 is separated from the flip cover 35. At this time, under the action of the reset spring 37, the flip cover 35 rotates in the opposite direction and re-covers the opening of the protective shell 31.

At the same time, it can also prevent dust, debris, etc. from entering the inside of the protective shell 31.

[0039] The reset assembly 25 includes a connecting plate 251, and sliding rods 252 are fixedly connected to both sides of the connecting plate 251.

The outer side of the fixed shell 21 is fixedly connected to one end of the tension spring 253 away from the connecting plate 251. When the right-angle limit plate 24 is deflected, the outer side of the right-angle limit plate 24 contacts the top block 255 in the reset assembly 25, and forces the top block 255 to push the connecting plate 251 to the side away from the fixed shell 21 through the sliding rod 252. At this time, the tension spring 253 is stretched by force.

[0040] When the inspection device 3 needs to be removed, it is only necessary to pull the two sliding plates 263 to both sides along the rectangular hole 254 to move the two sliding plates 263 away from each other. At this time, the elastic force of the tension spring 253 can restore the right-angle limit plate 24 to its initial state. At the same time, the movement of the right-angle limit plate 24 can be used to reset the push plate 22, and then the inspection device 3 can be pushed out of the fixed shell 21. This design makes the disassembly process simple and quick, without the need for complicated tools and cumbersome steps. The operator can easily push the inspection device 3 out of the fixed shell 21, thereby improving the efficiency of equipment maintenance and replacement.

[0041] The locking assembly 26 includes a limit block 261, the inner wall of the limit block 261 is slidably connected with an insertion rod 262, the outer wall of the insertion rod 262 is fixedly connected with a sliding plate 263, the outer side of the sliding plate 263 is fixedly connected with a compression spring 264, the outer wall of the insertion rod 262 is plugged with the inner wall of the sliding rod 23 through a socket 27, and the socket 27 is opened in the wall of the sliding rod 23, the outer wall of the limit block 261 is fixedly connected with the outer wall of the fixed shell 21, the end of the compression spring 264 away from the sliding plate 263 is fixedly connected to the inner side of the limit block 261, and the outer wall of the sliding plate 263 is connected to the connecting plate through a rectangular hole 254. The inner wall of 251 is slidably connected. With the displacement of the push plate 22, the slide bar 23 gradually slides to the outside of the fixed shell 21. During the sliding process of the slide bar 23, when the socket 27 on its outer wall is aligned with the plug 262 in the locking assembly 26, under the action of the compression spring 264, the plug 262 slides out of the limit block 261 and is inserted into the socket 27, thereby locking the slide bar 23, and then fixing the position of the push plate 22 and the right-angle limit plate 24, preventing the right-angle limit plate 24 from detaching from the limit groove 39 during flight, reducing the possibility of accidents and improving the safety of inspection operations.

The fast-flowing air can quickly take away the heat on the heat sink 44, thereby improving the heat exchange efficiency. At the same time, the accelerated air flow also reduces the pressure inside the heat sink 4, forming a negative pressure state, which is conducive to the hot air in the protective shell 31 to flow to the heat sink 4 faster, preventing heat from accumulating in the protective shell 31, thereby keeping the inspection device 3 working within an appropriate temperature range.

[0043] Working principle:

[0044] When in use, the aircraft body 1 drives the entire inspection equipment to move to the vicinity of the power transmission and distribution line for inspection operations. The inspection device 3 is installed at the bottom of the aircraft body 1 and is fixed and connected by the assembly device 2. At the same time, heat dissipation devices 4 are installed on both sides of the inspection device 3 to ensure the heat dissipation requirements of the equipment during operation.

[0045] When installing the inspection device 3, the protective shell 31 is inserted into the inner side of the fixed shell 21. During the insertion process, the protective shell 31 pushes the push plate 22 inside the fixed shell 21 to move. At this time, the push plate 22 contacts the right-angle limit plate 24 and forces the right-angle limit plate 24 to deflect, thereby causing the right-angle limit plate 24 to snap into the limit groove 39. In this way, the inspection device 3 can be fixed, the operation process is simple, and the convenience of installation is improved.

[0046] At the same time, with the displacement of the push plate 22, the slide bar 23 gradually slides toward the outside of the fixed shell 21. During the sliding process of the slide bar 23, when the socket 27 on its outer wall is aligned with the plug 262 in the locking assembly 26, under the action of the compression spring 264, the plug 262 slides out of the limit block 261 and is inserted into the socket 27, thereby locking the slide bar 23, and then fixing the position of the push plate 22 and the right-angle limit plate 24, preventing the right-angle limit plate 24 from detaching from the limit groove 39 during flight, reducing the possibility of accidents and improving the safety of inspection operations.

[0047] During the deflection of the right-angle stop plate 24, the outer side of the right-angle stop plate 24 contacts the top block 255 in the reset assembly 25, and forces the top block 255 to push the connecting plate 251 to the side away from the fixed shell 21 through the sliding rod 252, and at this time, the tension spring 253 is stretched by force;

[0048] When the inspection device 3 needs to be removed, it is only necessary to pull the two sliding plates 263 to both sides along the rectangular hole 254 to move the two sliding plates 263 away from each other. At this time, the elastic force of the tension spring 253 can restore the right-angle limit plate 24 to its initial state. At the same time, the movement of the right-angle limit plate 24 can be used to reset the push plate 22, and then the inspection device 3 can be pushed out of the fixed shell 21. This design makes the disassembly process simple and quick, without the need for complicated tools and cumbersome steps. The operator can easily push the inspection device 3 out of the fixed shell 21, thereby improving the efficiency of equipment maintenance and replacement.

[0049] When the inspection device 3 is in use, the electric push rod 32 is started, and the output end of the electric push rod 32 pushes the moving frame 33 to slide inside the protective shell 31. The moving frame 33 drives the inspection probe 34 to slide to the outside of the protective shell 31. During this process, the elastic top plate 38 is first released from the flip cover plate 35, and the flip cover plate 35 is pushed open, so that the reset spring 37 is compressed along the outer side of the arc guide rail 36. At this time, the inspection probe 34 can be used to inspect the power transmission and distribution line;

[0050] When the flip cover 35 is pushed open, the return spring 37 is compressed along the outer side of the arc guide 36. The arc guide 36 provides a stable guide for the compression of the return spring 37, preventing the return spring 37 from being twisted or misplaced during the compression process. At the same time, the compression of the return spring 37 stores energy, providing power for the subsequent automatic closing of the flip cover 35.

[0051] When the inspection is completed, the electric push rod 32 contracts, driving the movable frame 33 to reset, so that the elastic top plate 38 is separated from the flip cover plate 35. At this time, under the action of the reset spring 37, the flip cover plate 35 rotates in the opposite direction and covers the opening of the protective shell 31 again. This action can effectively protect the inspection probe 34 and prevent it from being affected by external factors such as collision, dust, and moisture when it is not in working state, ensuring that it can work normally during the next inspection, and at the same time, it can also prevent dust, debris, etc. from entering the interior of the protective shell 31;

[0052] During the flight of the aircraft body 1, the surrounding air enters the inner side of the heat sink 4 through the ventilation plate 42 on the outer side of the mounting plate 41. At this time, the airflow blows the fan blades 46 to rotate along the rotating shaft 45 under the guidance of the guide plate 43. The fan blades 46 rotate under the blowing of the airflow, further accelerating the flow speed of the air inside the heat sink 4. The fast-flowing air can quickly take away the heat on the heat sink 44 and improve the heat exchange efficiency. At the same time, the accelerated air flow also reduces the pressure inside the heat sink 4, forming a negative pressure state, which is conducive to the hot air in the protective shell 31 to flow to the heat sink 4 faster, preventing heat from accumulating in the protective shell 31, thereby keeping the inspection device 3 working within a suitable temperature range.

[0053] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
