Description

Technical Field

[0001] This invention relates to the field of surveying drone technology, and more specifically, to a surveying drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. Mapping UAVs are also a type of UAV. They complete mapping and data collection work by installing a mapping camera on the bottom of the UAV and controlling the rotation of the camera through a controller.

[0003] However, when surveying drones are used outdoors, the harsh outdoor environment, with its abundance of insects and dust, causes the camera surfaces to become covered in dust and impurities after prolonged use. Most surveying drones lack self-cleaning mechanisms for their cameras, necessitating manual cleaning when necessary, which significantly reduces their operational efficiency. Summary of the Invention

[0004] This invention provides a surveying drone to solve the problem of reduced work efficiency caused by cleaning in surveying drones in related technologies.

[0005] This invention provides a surveying drone, comprising: a main body including a fuselage, a camera, and a communication module; the camera is rotatably mounted on the fuselage, and the communication module is mounted on the fuselage and connected to the camera via a signal; and a cleaning assembly including a wiping component, a cleaning tank, and a driving component; the driving component is mounted on the fuselage and located to one side of the camera, the wiping component is located in front of the camera, and the driving component is driven to drive the wiping component to reciprocate in a straight line; the cleaning tank is mounted on the fuselage and has a liquid outlet facing the camera; wherein the wiping component has a wiping state and a retracted state; when the wiping component is in the wiping state, the wiping component is in contact with the camera and squeezes the cleaning tank, causing the cleaning tank to deform and allowing the liquid inside the cleaning tank to flow out from the liquid outlet to the camera; when the wiping component is in the retracted state, the wiping component is located to one side of the camera.

[0006] Furthermore, the wiping component includes a fixing plate and a cleaning cotton. The cleaning cotton is disposed on the side of the fixing plate facing the camera. The driving component is driven to connect with the fixing plate. When the wiping component is in the wiping state, the cleaning cotton is in contact with the camera, and the fixing plate is in contact with the cleaning box.

[0007] Furthermore, a liquid outlet pipe is provided at the liquid outlet hole, and a rotatable sealing plate is provided inside the liquid outlet pipe. The rotation axis of the sealing plate extends laterally. The sealing plate has a blocking state that blocks the liquid outlet pipe and a connecting state that connects the liquid outlet pipe to the outside. Both the fixing plate and the sealing plate are magnetic plates. When the wiping component is in the wiping state, the fixing plate can drive the sealing plate to move from the blocking state to the connecting state.

[0008] Furthermore, a connecting shaft extending laterally is provided inside the outlet pipe. The connecting shaft passes through the sealing plate, and a torsion spring is provided on the connecting shaft. The two ends of the torsion spring are connected to the connecting shaft and the sealing plate respectively, so that the sealing plate is kept in a sealed state; and / or, a filter screen is also provided inside the outlet pipe, and the filter screen is located above the sealing plate.

[0009] Furthermore, the surveying drone also includes an airbag mounted on the fuselage. A through hole is provided on the mounting plate, with the opening of the through hole facing the camera. The airbag is connected to the through hole. When the wiping component moves from the wiping state to the retracted state, the wiping component can squeeze the airbag to deform it, and the gas in the airbag flows out through the through hole to the camera.

[0010] Furthermore, the fixing plate includes a mounting plate extending vertically and a pressure plate extending laterally. The driving component is driven to the mounting plate. The cleaning cotton is disposed on the mounting plate. The through hole is disposed on the mounting plate. The lower surface of the pressure plate is connected to the upper surface of the mounting plate. When the wiping component is in the wiping state, the pressure plate squeezes the cleaning box.

[0011] Furthermore, the cleaning assembly also includes a cover plate rotatably disposed at the opening of the through hole, and an opening rod extending laterally is provided on the body. The opening rod is located between the drive unit and the cleaning tank. The cover plate has a latching position covering the opening of the through hole and an opening position that allows the through hole to communicate with the outside. When the wiping unit moves from the retracted state to the wiping state, the opening rod can drive the cover plate to move from the latching position to the opening position. When the wiping unit moves from the wiping state to the retracted state, the opening rod can drive the cover plate to move from the opening position to the latching position.

[0012] Furthermore, the rotation axis of the cover plate extends vertically, and a protrusion is provided on the side wall of the cover plate. A first inclined surface is provided on the protrusion, and a second inclined surface is provided at the end of the opening rod. In the direction of the opening rod pointing towards the cleaning tank, the distance between the first inclined surface and the machine body gradually decreases, while the distance between the second inclined surface and the machine body gradually increases. When the wiping component moves from the retracted state to the wiping state, the first inclined surface can fit with the second inclined surface, so that the cover plate moves from the fastened position to the open position. When the wiping component moves from the wiping state to the retracted state, the second inclined surface can fit with the surface of the cover plate facing the machine body, so that the cover plate moves from the open position to the fastened position.

[0013] Furthermore, the machine body includes a mounting frame and a housing located below the mounting frame. The camera is located inside the housing, and the cleaning tank and drive unit are both located on the outer wall of the housing. The communication module is located on the mounting frame. The housing also contains a squeezing plate and a guide plate. The squeezing plate is located on the side of the camera near the drive unit, and the cleaning cotton can fit in contact with the squeezing plate. The guide plate is located below the camera and is inclined towards the fixed plate.

[0014] Furthermore, the main body also includes a protective cover installed on the machine body, and the drive component is installed inside the protective cover; the drive component is arranged horizontally, and the cleaning box is located above the wiping component; the main body also includes multiple brackets connected to the machine body, the multiple brackets are arranged at intervals along the circumference of the machine body, and each bracket is equipped with a rotatable fan blade.

[0015] The technical solution of this invention provides a surveying drone comprising a main body and a cleaning component. During operation, the drone uses a camera to survey the area to be mapped and a communication module to transmit data and control signals between the drone and a data analysis terminal. When cleaning is required, a drive unit moves a wiping component in a straight line, switching between a wiping state and a retracted state. When the wiping component moves from the retracted state to the wiping state, it squeezes the cleaning tank, causing it to deform. Liquid inside the cleaning tank flows out through the outlet to the camera, and the wiping component then wipes the camera. This eliminates the need for the surveying drone to return to its home base for cleaning, thus improving the drone's operational efficiency. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, this embodiment of the invention provides a surveying drone, which includes a main body and a cleaning component. The main body includes a fuselage 1, a camera 4, and a communication module 2. The camera 4 is rotatably mounted on the fuselage 1, and the communication module 2 is mounted on the fuselage 1 and connected to the camera 4 via a signal. The cleaning component includes a wiping component, a cleaning tank 10, and a driving component 6. The driving component 6 is mounted on the fuselage 1 and located to one side of the camera 4. The wiping component is located in front of the camera 4, and the driving component 6 is driven to drive the wiping component to move back and forth in a straight line. The cleaning tank 10 is mounted on the fuselage 1 and has a liquid outlet facing the camera 4. The wiping component has a wiping state and a retracted state. When the wiping component is in the wiping state, it is in contact with the camera 4 and squeezes the cleaning tank 10, causing the cleaning tank 10 to deform and allowing the liquid in the cleaning tank 10 to flow out from the liquid outlet to the camera 4. When the wiping component is in the retracted state, it is located to one side of the camera 4.

[0028] The technical solution of this invention provides a surveying drone comprising a main body and a cleaning component. During operation, the drone uses a camera to survey the area to be mapped and a communication module to transmit data and control signals between the drone and a data analysis terminal. When cleaning is required, a drive unit moves a wiping component in a straight line, switching between a wiping state and a retracted state. When the wiping component moves from the retracted state to the wiping state, it squeezes the cleaning tank, causing it to deform. Liquid inside the cleaning tank flows out through the outlet to the camera, and the wiping component then wipes the camera. This eliminates the need for the surveying drone to return to its home base for cleaning, thus improving the drone's operational efficiency.

[0029] It should be noted that the cleaning tank 10 adopts a flexible structure, such as rubber. In order to ensure the structural strength of the cleaning tank 10, a high-strength material is provided on the side of the cleaning tank away from the drive component to protect the cleaning tank 10.

[0030] The wiping device can be of various types, such as cleaning cotton or cleaning cloth.

[0031] In this embodiment, the driving component 6 is an electric push rod.

[0032] It should be noted that the electric push rod can extend laterally, in which case the cleaning tank 10 is located above or below the electric push rod. The electric push rod can also extend vertically, in which case the cleaning tank 10 is located to the left or right of the electric push rod.

[0033] like Figure 3 and Figure 5 As shown, the wiping component includes a fixing plate and a cleaning cotton 8. The cleaning cotton 8 is disposed on the side of the fixing plate facing the camera 4. The driving component 6 is drivenly connected to the fixing plate. When the wiping component is in the wiping state, the cleaning cotton 8 is in contact with the camera 4, and the fixing plate is in contact with the cleaning tank 10. The wiping component with the above structure can fix the cleaning cotton 8 with the fixing plate and wipe the camera 4 with the cleaning cotton 8, which has the advantage of simple structure.

[0034] like Figure 3 and Figure 4 As shown, a liquid outlet pipe 11 is provided at the liquid outlet hole, and a rotatable sealing plate 13 is provided inside the liquid outlet pipe 11. The rotation axis of the sealing plate 13 extends laterally. The sealing plate 13 has a blocking state that blocks the liquid outlet pipe 11 and a connecting state that allows the liquid outlet pipe 11 to communicate with the outside. Both the fixing plate and the sealing plate 13 are magnetic plates. When the wiping component is in the wiping state, the fixing plate can drive the sealing plate 13 to move from the blocking state to the connecting state. By using the sealing plate 13 to block the liquid outlet pipe 11 and using the fixing plate to drive the sealing plate 13 to rotate so that it moves from the blocking state to the connecting state, the dispensing of cleaning agent can be automated.

[0035] In other embodiments, the outlet can be configured as an elastic structure. In the blocked state, the elastic structure can be used to automatically close the outlet, and in the connected state, the pressure of the cleaning agent can be used to open the outlet.

[0036] In this embodiment, the sealing plate 13 is an arc-shaped plate, which can guide the cleaning agent to the surface of the camera 4.

[0037] It should be noted that the fixing plate and the sealing plate 13 can be driven to move from the blocking state to the connecting state by the attraction of like poles, or the sealing plate 13 can be driven to rotate by the repulsion of opposite poles.

[0038] like Figure 4 As shown, a connecting shaft extending laterally is provided inside the liquid outlet pipe 11. The connecting shaft passes through the sealing plate 13. A torsion spring is provided on the connecting shaft. The two ends of the torsion spring are connected to the connecting shaft and the sealing plate 13 respectively, so that the sealing plate 13 is kept in the sealing state. With the help of the torsion spring, the sealing plate 13 can be automatically rotated so that it can be automatically reset from the connected state to the sealed state.

[0039] In this embodiment, a filter screen 12 is also provided inside the liquid outlet pipe 11, and the filter screen 12 is located above the sealing plate 13. The filter screen 12 can disperse the cleaning agent and filter out impurities in the cleaning agent.

[0040] The dispersed cleaning agent is guided by the sealing plate 13 to flow onto the surface of the camera 4.

[0041] like Figure 3 and Figure 5 As shown, the mapping drone also includes an airbag (not shown) mounted on the fuselage 1. A through-hole 16 is provided on the mounting plate, with the opening of the through-hole 16 facing the camera 4. The airbag is connected to the through-hole 16. When the wiping component moves from the wiping state to the retracted state, it can squeeze the airbag, causing it to deform. The gas in the airbag flows out through the through-hole 16 to the camera 4. Using this structure, the wiping component can squeeze the airbag, causing the gas in the airbag to be ejected through the through-hole 16 and drying the camera 4.

[0042] The airbag is designed to release air when compressed and draw in air when inflated. For example, an air pump that intermittently draws in and releases air can be connected to the airbag to control it.

[0043] It should be noted that the wiping component includes a drive plate, which is mounted on a fixed plate to compress the airbag.

[0044] like Figure 3As shown, the fixing plate includes a mounting plate 7 extending vertically and a pressure plate 9 extending horizontally. A driving member 6 is drivenly connected to the mounting plate 7. A cleaning cotton 8 is disposed on the mounting plate 7, and a through hole 16 is provided on the mounting plate 7. The lower surface of the pressure plate 9 is connected to the upper surface of the mounting plate 7. When the wiping member is in the wiping state, the pressure plate 9 presses against the cleaning tank 10. The fixing plate with the above structure can fix the cleaning cotton 8 using the mounting plate 7 while simultaneously providing the through hole 16. At the same time, the pressure plate 9 can also press against the cleaning tank 10, offering the advantage of a simple structure.

[0045] like Figure 5 As shown, the cleaning assembly also includes a cover plate 17 rotatably disposed at the opening of the through hole 16. An opening rod 19 extending laterally is provided on the body 1, located between the drive member 6 and the cleaning tank 10. The cover plate 17 has a latching position covering the opening of the through hole 16 and an open position allowing the through hole 16 to communicate with the outside. When the wiping member moves from a retracted state to a wiping state, the opening rod 19 can drive the cover plate 17 from the latching position to the open position. When the wiping member moves from the wiping state to a retracted state, the opening rod 19 can drive the cover plate 17 from the open position to the latching position. The cover plate 17 can be used to seal the through hole 16 to prevent it from becoming blocked. Simultaneously, the opening rod 19 can be used to switch the cover plate 17 between the latching and open positions, offering the advantage of a simple structure.

[0046] In other embodiments, the opening lever 19 can be configured as an electric push lever, which controls the rotation of the cover plate 17 by extending the electric push lever. In this case, after cleaning the camera 4 with cleaning agent, the cover plate 17 can be opened by extending the electric push lever, and the camera 4 can be dried using the gas in the through hole 16.

[0047] In this embodiment, there are multiple through holes 16, and multiple cover plates 17 are also provided corresponding to the through holes 16. The multiple through holes 16 are spaced apart along the width direction of the mounting plate 7. Using the opening rod 19, the multiple cover plates 17 can be switched between the latched position and the open position. The cover plate 17 is provided with a sealing ring, which can be used to seal the through holes 16.

[0048] like Figure 5As shown, the rotation axis of the cover plate 17 extends vertically. A protrusion 18 is provided on the side wall of the cover plate 17, and a first inclined surface is provided on the protrusion 18. A second inclined surface is provided at the end of the opening rod 19. In the direction from the opening rod 19 to the cleaning tank 10, the distance between the first inclined surface and the machine body 1 gradually decreases, while the distance between the second inclined surface and the machine body 1 gradually increases. When the wiping component moves from the retracted state to the wiping state, the first inclined surface can fit against the second inclined surface, allowing the cover plate 17 to move from the locked position to the open position. When the wiping component moves from the wiping state to the retracted state, the second inclined surface can fit against the surface of the cover plate 17 facing the machine body 1, allowing the cover plate 17 to move from the open position to the locked position. Using the above configuration, the first and second inclined surfaces cooperate to move the cover plate 17 from the locked position to the open position, and the second inclined surface cooperates with the surface of the cover plate 17 to move the cover plate 17 from the open position to the locked position, offering the advantage of a simple structure.

[0049] Specifically, when the wiping component moves from the retracted state to the wiping state, the electric push rod extends, pushing the fixing plate towards the camera 4. During this process, the cover plate 17 gradually approaches the opening rod 19, and the second inclined surface cooperates with the first inclined surface to move the cover plate 17 from the locked position to the open position. However, at this time, since the airbag is in a state of gradual expansion, no gas flows out of the through hole 16. Only the pressure plate 9 compresses the cleaning tank 10, and through the magnetic cooperation between the pressure plate 9 and the sealing plate 13, the sealing plate 13 is switched from the blocked state to the open state, allowing the cleaning agent to clean the camera 4, and the cleaning cotton 8 is used to wipe the camera 4. During the retraction of the electric push rod, the airbag is compressed. At this time, the gas in the airbag is discharged through the through hole 16 and the camera 4 is dried. After drying, the cover plate 17 can be closed by cooperating with the surface of the opening rod 19.

[0050] like Figure 1 and Figure 3 As shown, the machine body 1 includes a mounting bracket and a housing 3 located below the mounting bracket. A camera 4 is housed inside the housing 3. A cleaning tank 10 and a drive unit 6 are both mounted on the outer wall of the housing 3. A communication module 2 is mounted on the mounting bracket. The housing 3 also contains a squeezing plate 22 and a guide plate 23. The squeezing plate 22 is located on the side of the camera 4 closest to the drive unit 6, allowing the cleaning cotton 8 to adhere to it. The guide plate 23 is located below the camera 4 and is inclined towards the mounting plate. The machine body 1 with this structure has the advantages of simple structure and ease of installation.

[0051] In this embodiment, the squeezing plate 22 has a protruding structure that can squeeze the cleaning cotton 8 to squeeze out the liquid in the cleaning cotton 8, thereby drying the cleaning cotton. The guide plate 23 can guide the liquid used to clean the camera 4 and the liquid squeezed out from the cleaning cotton 8 to prevent the liquid from entering the camera 4.

[0052] like Figure 1 As shown, the main body also includes a protective cover 5 disposed on the body 1, and the drive component 6 is disposed inside the protective cover 5. The protective cover 5 can protect the drive component 6 from damage.

[0053] The drive unit 6 is arranged laterally, and the cleaning box 10 is located above the wiping unit. The above structure has the advantage of being easy to set up, and at the same time, it can make full use of the lateral space of the UAV.

[0054] In this embodiment, the main body also includes a plurality of brackets 25 connected to the body 1. The plurality of brackets 25 are arranged at intervals along the circumference of the body 1, and each bracket 25 is provided with a rotatable fan blade 26.

[0055] The following describes the specific process of camera cleaning:

[0056] When the driving component 6 extends, the wiping component moves from the retracted state to the wiping state. The driving component 6 drives the mounting plate 7 to move towards the camera 4. During this process, the cover plate 17 gradually approaches the opening rod 19, and the second inclined surface cooperates with the first inclined surface to move the cover plate 17 from the latched position to the open position. Next, the pressure plate 9 compresses the cleaning tank 10, and through the magnetic cooperation between the pressure plate 9 and the sealing plate 13, the sealing plate 13 is switched from the blocking state to the open state, allowing the liquid in the cleaning tank 10 to flow out through the outlet pipe 11 to the surface of the camera 4 for cleaning. At the same time, the cleaning cotton 8 wipes the camera 4. When the driving component 6 retracts, the cleaning cotton 8 continues to wipe the camera 4. After the pressure plate 9 separates from the cleaning tank 10, the cleaning tank 10 returns to its initial state, and the sealing plate 13 automatically returns to the blocking state under the elastic force of the torsion spring. Simultaneously, the fixed plate compresses the airbag, and the gas in the airbag is discharged through the through hole 16, drying the camera 4. After drying, when the opening rod 19 is passed, the opening rod 19 engages with the surface of the cover plate 17, causing the cover plate 17 to move from the open position to the latched position, thereby closing the through hole 16. This cycle is repeated to clean the camera 4.
