Description

Technical Field

[0001] The invention relates to a professional equipment for road operation, in particular to an unmanned aerial vehicle road marking machine suitable for rapid and emergency construction operations. Background Art

[0002] Road marking is an important task in municipal construction operations, which plays an important role in road safety. At present, road marking is generally carried out by construction vehicles or by manual hand-pushing through marking equipment for spraying and marking. Although the above two existing construction methods can achieve the purpose of marking, their marking efficiency is relatively low, especially the method of using manual hand-pushing marking equipment for operation, which is even more inefficient, resulting in high construction costs. In addition, when construction is carried out on sections with fewer pedestrians or high-speed sections, the vehicle speed is often faster. At this time, the use of manual operation methods is likely to have safety hazards. In addition, during the existing marking construction operations, due to the presence of construction vehicles, the rear vehicles cannot directly observe the road conditions ahead, which often makes the rear vehicles mistakenly believe that the front vehicles are driving slowly. Therefore, wrong judgments are likely to cause traffic congestion problems and affect traffic conditions. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a UAV road marking machine which is quick and convenient to construct, thereby greatly improving construction efficiency and effectively avoiding traffic congestion problems and improving construction operation safety.

[0004] In order to solve the above technical problems, the unmanned aerial vehicle road marking machine of the present invention includes a unmanned aerial vehicle body and a marking machine body connected to the bottom of the unmanned aerial vehicle body, the marking machine body includes an outer shell and a plurality of injection assemblies arranged in the outer shell, and a filling tube for providing a fuel bag to each nozzle is arranged on the side wall of each injection assembly, and the end of the injection assembly has a nozzle located at the bottom of the outer shell. After the filling tube is filled with the fuel bag, the dye bag can be sprayed out from the nozzle by starting the injection assembly to perform marking operations.

[0005] The injection assembly also includes a nozzle, an electromagnet fixedly installed in the nozzle, a trigger installed in the nozzle and capable of reciprocating relative to the electromagnet, a return spring installed in the nozzle and installed in conjunction with the trigger, and a compressed air chamber arranged next to the nozzle. A buffer limit plate is also arranged in the nozzle below the trigger.

[0006] The buffer limit plate is connected in the nozzle through a buffer spring, and the end of the filling pipe is provided with a material guide bin connected with the nozzle.

[0007] The rear end surface of the trigger is provided with an inclined surface corresponding to the air outlet of the compressed air chamber.

[0008] An isolation chamber divided by a plurality of partitions is arranged in the shell, and each of the injection assemblies and an injection device consisting of a stuffing pipe matched with each of the injection assemblies are respectively fixedly installed in each of the isolation chambers.

[0009] The top of the filling tube is provided with a filling port for filling the fuel bag.

[0010] A control box is arranged on the side wall of the shell.

[0011] A connecting shaft is arranged at the top of the marking machine body, and the marking machine body is connected and fixed to the bottom of the drone body through the connecting shaft.

[0012] The drone body is provided with a voice broadcast unit, through which construction operation information can be broadcasted.

[0013] The drone body is provided with a warning sign located on the front side of the marking machine body.

[0014] A warning light bar is arranged on the edge of the warning sign.

[0015] The advantages of the present invention are: (1) By directly setting the marking machine body at the bottom of the drone body, the drone can be used for marking operations, and manual marking is no longer required, which greatly improves the operation efficiency. In addition, due to the aerial operation mode of the drone, its work is more flexible and convenient, further improving the construction efficiency and reducing the construction cost.

[0016] (2) Through the warning sign installed on the front side of the marking machine body, the driver can see the warning sign hanging in the air in advance during construction work, and directly obtain the construction information ahead through the warning sign. Therefore, the driving trajectory can be adjusted in time, which not only ensures construction safety but also avoids traffic congestion caused by construction work.

[0017] (3) Through the voice broadcast unit installed in the drone body, in addition to the intuitive warning of the warning sign, the voice broadcast unit can also broadcast construction work information. The voice information it broadcasts can effectively remind moving vehicles that there is construction ahead and they can take a detour, further ensuring construction safety and effectively avoiding traffic congestion caused by construction work.

[0018] (4) The marking machine body is composed of an outer shell, a plurality of injection assemblies arranged in the outer shell, and a filling tube arranged on the side wall of each injection assembly. The structure design is reasonable and the overall volume is moderate. It is easy to be carried by an unmanned aerial vehicle and to be controlled during construction. After the fuel bag is filled in the filling tube, the dye bag can be sprayed out from the nozzle by starting the injection assembly to carry out the marking operation. The manufacturing cost is low and the work efficiency is high.

[0019] (5) The spray assembly is mainly composed of a nozzle, an electromagnet fixed in the nozzle, a trigger installed in the nozzle and capable of reciprocating relative to the electromagnet, a return spring installed in the nozzle and coordinated with the trigger, and a compressed air chamber arranged beside the nozzle. The spray assembly has a reasonable structural design and good reliability. In particular, the electromagnet trigger, return spring and compressed air chamber are cleverly designed, so that it has a special effect of spray marking, which is completely different from traditional spray marking and is more efficient.

[0020] (6) The UAV road marking machine can be directly used on sections of roads with fewer pedestrians or on highways, which not only reduces the number of on-site workers, but also eliminates the need for on-site workers in some sections, effectively reducing safety hazards and ensuring the safety of construction operations. It is particularly suitable for situations where rapid emergency construction operations are required. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The UAV road marking machine of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] As shown in the figure, the unmanned aerial vehicle road marking machine of the present invention comprises an unmanned aerial vehicle body 1 and a marking machine body 2 connected to the bottom of the unmanned aerial vehicle body. In this embodiment, a connecting shaft 14 can be provided at the top of the marking machine body 2, and the marking machine body 2 is connected and fixed to the bottom of the unmanned aerial vehicle body through the connecting shaft. The marking machine body 2 comprises an outer shell 3 and a plurality of injection assemblies 4 arranged in the outer shell. As can be seen from the figure, each of the injection assemblies 4 comprises a nozzle 6, an electromagnet 7 fixedly installed in the nozzle, a trigger 8 installed in the nozzle and capable of reciprocating relative to the electromagnet, and a nozzle 6 installed in the nozzle. The return spring 9 is installed in cooperation with the trigger 8, the compressed air chamber is arranged beside the nozzle 6, and the filling tube 5 is arranged on the side wall of the injection assembly for providing fuel bags to each nozzle. The end of the nozzle 6 has a nozzle 16 located at the bottom of the shell. The nozzle 16 is also provided with a buffer limit plate 10 located below the trigger 8. The buffer limit plate 10 is connected to the nozzle through a buffer spring 11. The end of the filling tube 5 has a guide bin 12 connected to the nozzle 16. After the filling tube 5 is filled with the fuel bag, the dye bag can be sprayed out from the nozzle by starting the injection assembly 4 to perform marking operations.

[0024] Furthermore, the rear end face of the trigger 8 is provided with a slope 11 corresponding to the gas outlet of the compressed gas chamber, and a sealing ring is provided between the trigger 8 and the nozzle 6, so that the trigger forms a piston-like motion mechanism, and the compression chamber is filled with compressed gas, so that the gas in the compression chamber can directly impact the slope, and the trigger 8 moves downward rapidly under the action of the slope. In this process, the slope also serves as a guide surface that enables the gas to quickly enter the trigger and the electromagnet, so that its operation is reliable.

[0025] Furthermore, the shell 3 is provided with an isolation chamber 12 divided by a plurality of partitions. As can be seen from the figure, the inner chamber of the shell can be divided into a plurality of rectangular cavities as the isolation chamber 12 by the partitions, and each nozzle 4 is placed in each rectangular cavity. For example, in the present embodiment, the number of nozzles 6 is 5×8 (5 rows and 8 columns), and the corresponding filling tubes 5 must also be 5 rows and 8 columns, so 40 isolation chambers will be set. Of course, in order to improve the marking effect, more injection assemblies 4 can be set. During installation, the injection devices composed of each injection assembly 4 and the filling tubes 5 matched with each injection assembly are fixedly installed in each isolation chamber respectively, and a filling port 13 for filling the fuel bag is opened on the top of the filling tube 5.

[0026] Furthermore, a control box 15 is provided on the side wall of the housing 3, and the electromagnet is sealed and fixedly installed in the nozzle. The control line of the electromagnet is led out from the top of the nozzle and connected to the control circuit of the control box.

[0027] Furthermore, a voice broadcast unit can be provided in the drone body 1, and construction work information can be broadcasted through the voice broadcast unit. The voice broadcast unit can adopt the voice playback function of the drone body, and construction work information can be broadcasted through the voice broadcast unit. A warning sign located on the front side of the marking machine body 2 is installed on the drone body 1. In addition, a warning light bar can be provided on the edge of the warning sign, and the warning bar can better serve the purpose of warning.

[0028] In addition, eight grooves corresponding to the rows of filling tubes 5 can be opened on the top of the shell, thereby eight filling plugs 13 can be designed, each sealing plug is composed of a rectangular plate and five circular plugs arranged under the rectangular plate, so that after filling the dye packs into each filling tube, the sealing plugs can be sealed in each groove.

[0029] When in use, the marking machine body 2 is connected and fixed to the bottom of the drone body through the connecting shaft. The user uploads the picture to the flight control of the drone, and the control system recognizes it as a 5*8 grid pattern. The cylindrical electromagnet 7 in each injection assembly is controlled by the control circuit in the control box. After power is turned on, magnetic force is generated, and the magnetic suction cup of the electromagnet 7 sucks the iron material trigger 8, and the compressed gas in the compressed gas chamber is compressed. When the dye bag needs to be launched, the electromagnet is powered off, and the magnetic force disappears. After the magnetic suction cup does not suck the trigger in the nozzle and the compressed air in the compressed gas chamber expands rapidly, the inclined surface can be used to The compressed air quickly enters between the trigger and the electromagnet and under the action of the inclined plane, the trigger moves downward quickly, triggering the dye bag on the buffer limit plate 10 that enters from the filling tube 5 and knocks the dye bag out. After being knocked out, the reset spring 9 resets the trigger, and the control circuit in the control box controls the cylindrical electromagnet 7 in each injection assembly. After power is turned on, magnetic force is generated, and the magnetic suction cup of the electromagnet 7 again attracts the trigger 8, and at the same time, the compressed gas in the compressed air chamber is compressed again for the next launch, that is: after one pattern is sprayed, the aircraft flies to the next position and then sprays again, thereby performing the spraying work of different ground markings.

[0030] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
