Description

Technical Field

[0001] The present invention belongs to the technical field of transportation tools and relates to unmanned aerial vehicle (UAV) transportation, and in particular to an unmanned aerial vehicle (UAV) transport vehicle for cleaning lamps in tunnels. Background Art

[0002] In order to overcome the "black hole effect" or "white hole effect" caused by the sudden change in brightness when a vehicle enters or exits a tunnel, it is necessary to install lamps for tunnel lighting in the tunnel. After long-term use or a fire in the tunnel, the surface of the lamps is covered with dust and needs to be cleaned. The existing cleaning method is to drive an aerial work vehicle into the tunnel or build a rolling aerial work platform to enter the tunnel for high-altitude cleaning operations. This operation method is inefficient and unsafe.

[0003] Using drones to inspect and clean buildings and roads is convenient, efficient, and safe, and has been gradually promoted. Chinese patent CN206822590 discloses a drone cleaning system. After a vehicle transports a drone to a designated location, the drone takes off for cleaning. In this patent, the drone carries its own water pump and medicine box, and starts spraying liquid medicine for cleaning when it flies near a building. However, this method has a larger load due to the drone's own water pump and medicine box, and requires a large-sized, high-power drone. The space in the tunnel is narrow, and the use of a large-sized drone is very likely to touch the tunnel wall, causing the drone to lose control, and is not suitable for cleaning operations in the tunnel. Summary of the invention

[0004] In view of the defects of the above-mentioned prior art, the present invention discloses a drone transport vehicle for cleaning lamps in tunnels.

[0005] The drone transport vehicle for cleaning lamps in tunnels described in the present invention includes a main water tank installed in the cargo compartment and a first water pump connected to the main water tank; it also includes a drone take-off and landing platform, and a lifting device is installed under the drone take-off and landing platform; a relay water tank and a second water pump are installed on the drone take-off and landing platform, and the relay water tank is connected to the first water pump and the second water pump, and a cable gallows is also installed on the drone take-off and landing platform, and the output end of the second water pump is connected to a water pipe, and the water pipe is wound on the cable gallows, and a drone take-off and landing area is set on the drone take-off and landing platform; the drone transport vehicle is also provided with a control system for controlling the drone, the water pump, the lifting device and the cable gallows, and exchanging information with the drone.

[0009] When the height detected by the height sensor is higher than the first preset height, the cable hangar is controlled to rotate to release the cable, otherwise it does not rotate;

[0010] The control mode of the control system when the drone returns is:

[0011] When the height detected by the height sensor is lower than the second preset height, the cable gallows is controlled to rotate to recycle the cable, otherwise it does not rotate.

[0012] Preferably, a rotating shaft is provided on the UAV take-off and landing platform, a UAV landing platform is installed on the top of the rotating shaft, the connection between the rotating shaft and the UAV landing platform is located on one side of the center point on the central axis of the UAV landing platform, and the rotating shaft is connected to the control system signal.

[0019] The present invention is used for the drone transport vehicle for cleaning lamps in tunnels.

DETAILED DESCRIPTION

[0028] In order to more intuitively and clearly describe the specific details of the technical solution of the present invention, a detailed description will be given below in conjunction with specific embodiments and example drawings.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in combination with the specific implementation methods of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, the drone transport vehicle for cleaning lamps in tunnels described in the present invention comprises a main water tank 1 installed in the cargo compartment, a first water pump 3 connected to the main water tank 1 and a drone landing platform 2, a lifting device is installed under the drone landing platform, generally a hydraulic lifting frame; a relay water tank 5 and a second water pump 4 are installed on the drone landing platform, the relay water tank 5 is connected to the first water pump 3 and the second water pump 4, a cable gallows 6 is also installed on the drone landing platform, the output end of the second water pump is connected to a water pipe, the water pipe is wound on the cable gallows 6, a drone landing area is provided on the drone landing platform, which is used to dock a drone 7 with a spray gun for cleaning; the drone transport vehicle is also provided with a control system for controlling equipment such as drones, water pumps, lifting devices and cable gallows, and for information exchange with the drone.

[0031] When in use, a vehicle with cleaning fluid in the main water tank drives into the tunnel and stops on one side of the lane in the tunnel. For a single-lane tunnel, it can be parked in the emergency parking area set up in the tunnel. For a shorter tunnel without an emergency parking area, it can be parked on the shoulder at the entrance and exit of the tunnel. The water pipe joint wrapped around the cable gallows is connected to the spray gun on the drone, and the lifting device is started to raise the drone landing platform 2 to a predetermined height. The first water pump 3 pumps the cleaning fluid stored in the main water tank 1 into the relay water tank 5 located on the drone landing platform.

[0032] After the relay water tank 5 is filled, the first water pump is turned off, and the control system controls the drone to drag the water pipe to take off and fly horizontally to the lamps in the tunnel. The second water pump 4 is turned on to pressurize the cleaning liquid from the relay water tank 5 into the water pipe. The operator controls the flight posture of the drone to spray the cleaning liquid on the lamps to be cleaned.

[0033] When the vehicle is driving to the operation point, the drone can be placed in the honeycomb drone hangar on the vehicle. After arriving at the operation point, the staff will place the drone on the drone landing platform 2, connect the water pipe on the cable rack to the spray gun on the drone, and start the first water pump 3 to fill the relay water tank with cleaning fluid for the drone; the drone 7 can also be fixed on the drone landing area of ​​the drone landing platform 2. For example, the drone fixing device disclosed in Chinese patent CN2019204477376 can be referred to, and an automatically unlocked drone fixing device can be set in the drone landing area. The drone can be fixed on the drone landing area during driving and unlocked before the drone takes off.

[0034] Since the drone in the present invention no longer carries a water pump and a medicine box, it only needs to install a spray gun and connect a water pipe. The drone load is greatly reduced, and a small multi-rotor drone can be used for cleaning operations. For example, a DJI Mavic 3M drone can be used. Its unfolded size is 347 mm long, 283 mm wide, and 139 mm high. After a simple modification, a spray gun can be installed for cleaning operations. Small-sized drones are more suitable for operations in narrow tunnels. At the same time, the drone only carries a spray gun for operation, which increases the range. After a single charge, the operating time can be increased to clean more lamps.

[0035] The lifting device is used to raise the UAV landing platform together with the relay water tank. On the one hand, when the UAV is performing cleaning operations, the height difference between the cable hanger installed on the UAV landing platform and the UAV can be reduced, the bending degree of the water pipe can be reduced, and the lowest point of the water pipe falling arc can avoid the front of the vehicle and other high places, avoiding repeated bending of the water pipe, resulting in reduced water pressure or entanglement of the water pipe, making it easier for the UAV to operate lamps far from the parking point and avoid interfering with driving in the tunnel. At the same time, due to the overall increase in the position of the relay water tank and the second water pump, the gravitational potential energy loss overcome by the second water pump pumping water from the relay water tank to increase the pressure in the water pipe is reduced, which actually increases the spray water pressure at the UAV spray gun, and can improve the operating distance and cleaning effect. The relay water tank can be set inside the UAV landing platform.

[0036] In the present invention, the water pipe and the drone control line, power line, etc. can be twisted together to form a cable connected to the drone to provide control signals, power and water sources for the drone. After wired power supply is realized, the working time of the drone can be further extended. The wired control method can also overcome the situation where the wireless signal is easily interfered with and causes the drone to lose control.

[0037] Figure 1In the specific embodiment shown, the lifting device is usually configured as two sets of front and rear hydraulic lifting frames. When the vehicle is parked at a sloped position, the lifting heights of the two hydraulic lifting frames can be adjusted to be different, so that the drone landing platform itself tilts and drives the drone landing platform to tilt, thereby compensating for the slope and making the drone landing platform horizontal, avoiding tipping and sliding of the drone when landing.

[0038] After the drone takes off, the operator controls the cable gantries to rotate and release the cables. According to the distance between the drone and the take-off point, a certain length of cable is released after considering the margin caused by the appropriate bending of the water pipe, so that the drone can fly normally without causing the bottom height of the cable to be too low to affect driving in the tunnel. During operation, more cables are usually released first, and the released cables will accumulate freely under the cable gantries. As the drone flies away, the released cables are gradually dragged.

[0039] When the drone returns after the operation, the operator observes the height of the lowest point of the cable. When the height is reduced to a level that may affect tunnel driving, the operator controls the drone to temporarily hover and control the cable gantries to reverse and recycle the cables. The height of the lowest point of the cable is raised, and the operator then controls the drone to gradually return and land on the drone landing platform.

[0040] Since the present invention adopts an elevated UAV landing platform, the cable connection point is set on the cable gantries on the UAV landing platform, the angle of the cable in the gravity direction becomes smaller, and it is not easy to be blocked or entangled by the components on the vehicle, which can ensure the smoothness of the cable gantries when recovering the cables.

[0041] like Figure 3 The figure shows a specific implementation of the cable winch, including a fixed base 61 fixed on the UAV landing platform, a first winch 62, a second winch 63 rotatably fixed on the fixed base, and a cable support rod 64 connected between the two winches. A rotatable water pipe connecting port 66 is provided at the center of the first winch. The outer side of the water pipe connecting port 66 is connected to the second water pump 4 through a pipeline, and the inner side is connected to the water pipe wound on the cable support rod 64. The second winch is provided with a winch shaft, and the winch shaft is connected to the winch motor 65 fixed on the fixed base.

[0042] The second water pump 4 pumps cleaning liquid from the relay water tank into the water pipe on the cable gallows through the pipeline and the water pipe connecting port. During use, when the water pipe needs to be released or recovered, the winch motor 65 drives the second winch 63 to rotate, so that the cable support rod 64 rotates, so that the water pipe wrapped on the cable gallows is released or recovered. Since the connection point between the water pipe and the cable gallows is located at the center of the circle of the first winch 62, the distance between the second water pump 4 and the first winch 62 remains unchanged during the rotation of the winch, and the water pipe will not detach. The cable support rod can be a single cylindrical rod; it can also be multiple rods, symmetrically distributed around the rotation axis of the cable gallows.

[0043] A preferred implementation of the cable winch is to place the cable winch vertically, that is, the second winch is located above the first winch, and the fixed seat is located between the first winch and the UAV landing platform. The water pipe connection port on the first winch is connected to the second water pump through a pre-buried pipe embedded in the UAV landing platform and the fixed seat. The cable winch is placed vertically so that the winch is horizontal. The horizontal space can be used to adopt a larger-sized winch placed horizontally to increase the cable winding length while keeping the height unchanged.

[0044] In a preferred embodiment, a collar can be installed on a water pipe or cable, such as Figure 7 As shown, the collar is composed of a first half shell 11 and a second half shell 12 of two different densities, for example, the first half shell 11 is made of plastic, and the second half shell 12 is made of steel, and both half shells are cylindrical with a semicircular cross-section, and the water pipe passes through the central through hole of the two half shells. A height sensor is installed in the center of the arc surface of the heavier second half shell 12, and the collar is movably sleeved on the cable. Since the collar can slide freely on the cable, the collar is always located at the lowest point when the cable is suspended and falling, and the bottom surface of the second half shell 12 always points to the ground. The height sensor emits sound waves or lasers to the ground, measures the current height of the collar according to the reflection time, and sends the measurement data back to the control system.

[0045] When the drone takes off and returns, the control system needs to control the lowest point of the cable according to the height of the loop to avoid falling to the ground or interfering with normal driving in the tunnel.

[0046] A first preset height and a second preset height are set in advance through the control system. The control system detects the height of the height sensor when the UAV takes off. The cable needs to be continuously released during the take-off phase. When the height detected by the height sensor is higher than the first preset height, it indicates that the cable is stretched too tight at this time, causing the height sensor to fall less, which may easily increase the flight resistance of the UAV. At this time, the cable gallows is controlled to rotate and release the cable. If the UAV is hovering at this time, the height sensor will fall until it is no higher than the first preset height. The UAV continues to move away from the transport vehicle. The height sensor may be higher than the first preset height during the unmanned flight, and the cable gallows continues to release the cable. When it is no higher than the first preset height, it indicates that the cable length for the UAV to move away is sufficient, and the cable gallows is controlled not to rotate.

[0047] When the UAV returns, the control system turns off the first water pump 3 and the second water pump 4 and detects the height of the height sensor. When the height detected by the height sensor is lower than the second preset height, it means that the UAV is flying close to the transport vehicle, so that the natural falling point of the cable is lower. At this time, the cable gallows is controlled to rotate to recycle the cable and raise the lowest point of the cable when it falls, so as to avoid scratching the ground or affecting the normal traffic of the lane. If the detected height is not lower than the second preset height, it will not rotate to avoid the cable dragging the UAV and causing it to lose control.

[0048] In the cargo compartment of the transport truck, a drone hive can be set up to store multiple drones. In addition to cleaning drones, warning drones can also be launched. By hovering in front of the lane and turning on sound and light, they remind vehicles traveling in the tunnel that there are drones in front of them performing cleaning operations, and passing vehicles should slow down and pass safely.

[0049] like Figure 4 Another preferred embodiment of the present invention is shown as shown, wherein a rotating shaft 10 is provided on the UAV take-off and landing platform, a UAV landing platform 9 is installed on the top of the rotating shaft, and the connection between the rotating shaft and the UAV landing platform is located on one side of the center point on the central axis of the UAV landing platform.

[0050] When the drone transport vehicle is driving or parked for standby without performing cleaning operations, the drone landing platform is placed in the same direction as the vehicle's driving direction, so that the drone landing platform completely covers the drone take-off and landing platform and is at the same height as the top of the side wall of the transport vehicle's cargo compartment. Together with the side walls and part of the roof of the transport vehicle's cargo compartment, a complete closed cargo compartment is formed for the drone take-off and landing platform, thereby protecting the drone, cable hangars and other equipment on the drone take-off and landing platform from damage caused by rain or falling objects from high altitude.

[0051] When cleaning is required, the drone landing platform 2 is first lifted, so that the drone landing platform 9 rises and separates from the side wall, and then the drone landing platform 9 is driven by the shaft to rotate 90 degrees. Figure 5As shown, the drone landing platform 9 is made to be perpendicular to the drone take-off and landing platform 2, so that the drone take-off and landing platform is no longer blocked by the drone landing platform above, and then the drone 7 is controlled to take off and perform cleaning operations.

[0052] After the drone 7 takes off from the drone landing platform 2 or the cleaning operation is completed, the drone can be operated to temporarily hover, and then the drone landing platform is rotated 90 degrees so that a part of the landing platform extends into the inside of the tunnel.

[0053] Because the drone transport vehicle is parked at the tunnel exit or in the parking area inside the tunnel when it is operating, the cable touches the corners of the tunnel side wall near the vehicle body after the drone takes off, causing the water pipe to be squeezed. On the one hand, the drone may be subjected to force and lose control. At the same time, the squeezing of the water pipe causes insufficient water pressure in the spray gun in front of the drone, affecting the cleaning operation.

[0054] The cable hanger can be installed under the side of the UAV landing platform extending out of the vehicle body. Figure 6 As shown, the fixing seat of the cable gantries is installed under the UAV landing platform. The water pipe between the UAV and the cable gantries does not need to turn at a large angle, which is convenient for reducing the resistance when the water pipe is released and recovered. When the UAV is operated to depart and return, the water pipe is roughly straight, which reduces the difficulty of operation and prevents the water pipe from touching the side wall of the tunnel.

[0055] After the drone landing platform 9 rotates, since the connection between the rotating shaft 10 and the drone landing platform 9 is located on one side of the center point of the drone landing platform's central axis, one end of the drone landing platform 9 extends far outside the vehicle body during cleaning operations, so that a part of the drone landing platform is located above the lane next to the vehicle; Figure 6 As shown, most of the UAV landing platform is suspended outside the vehicle body, and the relay water tank 5 and the second water pump 4 can be suspended on the side of the UAV landing platform 9 closer to the rotating shaft 10 to balance the weight on the other side. At the same time, the water tank and the water pump are connected by flexible water pipes.

[0056] When the vehicle is performing cleaning operations, for a single-lane tunnel, it can be parked in the emergency parking area set up in the tunnel. For a shorter tunnel without an emergency parking area, it can be parked on the shoulder at the tunnel entrance or exit. After the drone landing platform rotates, it is located above the vehicle and extends outward above the lane, so that the drone can fly along the tunnel lane and land directly without turning, reducing the difficulty of controlling the drone during landing.

[0057] Since the drone carried in this application is used for operation inside the tunnel, there are tunnel side walls in the parking area or tunnel entrance and exit beside the tunnel where the transport vehicle stops when the drone is operating, and the drone cannot land directly on the lane. In addition, when performing cleaning operations, it is preferably carried out at night when there are fewer vehicles passing, and some lights will be turned off when cleaning the lights in the tunnel, and the lighting conditions are poor. The drone has high requirements for manual operation when performing turning and landing operations. Once it touches the tunnel side wall, the drone will crash. The drone landing platform extends out above the driving lane, and there is no need to avoid the tunnel side wall when landing. It is easy to achieve a straight flight to the drone landing platform and then land. At the same time, the area above the drone landing platform is open, which is more conducive to the landing of the drone than the small area caused by equipment such as cable hangers on the drone landing platform.

[0058] After the drone lands on the drone landing platform, the rotating shaft can be controlled to rotate 45 degrees to approach the vehicle body first, and then the operator can board the drone landing platform to recover the drone from the drone landing platform to the drone landing platform. Since the present invention uses a small drone, such as the DJI Mavic 3M drone, which weighs less than 1 kilogram, it can be recovered by manpower.

[0059] After the drone recovers the drone hive fixed on the drone take-off and landing platform or in the cargo compartment, the drone landing platform is controlled to continue rotating to the position before the drone took off, and then the lifting device of the drone take-off and landing platform is controlled to descend, so that the height of the drone landing platform is lowered and the top of the cargo compartment is closed, and the transport vehicle returns to the state before the drone took off.

[0060] The foregoing describes various preferred embodiments of the present invention. Unless the preferred implementation modes in various preferred embodiments are obviously self-contradictory or based on a certain preferred implementation mode, various preferred implementation modes can be arbitrarily superimposed and used in combination. The embodiments and specific parameters in the embodiments are only for clearly describing the invention verification process of the inventor, and are not used to limit the patent protection scope of the present invention. The patent protection scope of the present invention shall still be based on its claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
