Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a slope rock mass surveying device based on UAVs. Background Technology

[0002] Slope rock mass surveying is a crucial task in geotechnical engineering, engineering geology, hydropower, transportation, and mining. Its core purpose is to determine the stability of slopes and provide a scientific basis for design, construction, and long-term safe operation.

[0003] When using drones to survey slope rock masses, staff need to record the target location when it is observed. However, when staff search for the location later, it is not possible to quickly determine whether the location is the target location. They need to repeatedly check the location against the location observed by the drone, which increases the staff's verification time. Utility Model Content

[0004] The purpose of this invention is to provide a slope rock mass surveying device based on unmanned aerial vehicles (UAVs) to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slope rock mass surveying device based on a drone, comprising a drone body and a surveying camera fixedly installed at one end of the bottom of the drone body, a mounting bracket being provided at the bottom of the drone body, a spraying mechanism being provided inside the mounting bracket, and a pushing mechanism being provided at the end of the mounting bracket away from the spraying mechanism.

[0006] Preferably, the spraying mechanism includes a spraying cylinder, one side of which is connected to a nozzle, a one-way valve is fixedly installed inside the nozzle, a piston is slidably arranged inside the spraying cylinder, a push rod is fixedly installed on one side of the piston, the push rod passes through the spraying cylinder and extends to the outside of the spraying cylinder, and a circular plate is fixedly installed on the side of the push rod away from the piston.

[0007] Preferably, one end of the top of the spray gun is connected to an injection pipe, and the injection pipe is externally threaded with a sealing cap.

[0008] Preferably, the mounting bracket has an internal mounting groove that cooperates with the spray gun. A fixing plate is rotatably mounted on the bottom of the mounting bracket near the spray gun. A fixing bolt is threaded onto the top of the fixing plate. A fixing hole is provided on the top of the mounting bracket near the fixing bolt, and the fixing hole cooperates with the fixing bolt.

[0009] Preferably, one end of the top of the mounting groove is connected to a recess, which cooperates with the injection pipe.

[0010] Preferably, the pushing mechanism includes an electric push rod, which is fixedly installed inside the mounting bracket. A push plate is fixedly installed at the telescopic shaft end of the electric push rod. A connecting groove is provided at the end of the push plate away from the electric push rod, and the connecting groove cooperates with the circular plate.

[0011] Preferably, a connecting plate is fixedly installed on the bottom of the drone body, and a rotary motor is fixedly installed on the side of the connecting plate away from the mounting bracket, and the output shaft end of the rotary motor is fixedly connected to the mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By using the spraying mechanism and surveying camera to survey the slope rock mass, the paint inside the spraying cylinder is sprayed through the nozzle to mark the target location after the target location is found. This makes it easier for subsequent staff to quickly determine the target location without having to check it against the location observed by the drone, thus shortening the verification time for subsequent staff.

[0013] 2. By making the spray gun and the mounting bracket detachable, it is easy to add pigment into the spray gun or replace the spray gun. The rotating motor can be used to adjust the angle at which the pigment is sprayed from the spray gun, thereby improving the accuracy of marking the target position. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: such as Figure 1 - Figure 7 The image shows a slope rock mass surveying device based on a drone, including a drone body 1 and a survey camera 2 fixedly installed at one end of the bottom of the drone body 1. A mounting bracket 3 is provided at the bottom of the drone body 1, and a spraying mechanism is provided inside the mounting bracket 3. A pushing mechanism is provided at the end of the mounting bracket 3 away from the spraying mechanism.

[0018] The spraying mechanism includes a spraying cylinder 4, a nozzle 7 connected to one side of the spraying cylinder 4, a one-way valve 8 fixedly installed inside the nozzle 7, a piston 9 slidably arranged inside the spraying cylinder 4, a push rod 10 fixedly installed on one side of the piston 9, the push rod 10 passes through the spraying cylinder 4 and extends to the outside of the spraying cylinder 4, and a circular plate 11 is fixedly installed on the side of the push rod 10 away from the piston 9.

[0019] One end of the top of the spray gun 4 is connected to an injection pipe 5, and a sealing cap 6 is threaded onto the outside of the injection pipe 5.

[0020] The mounting bracket 3 has an internal mounting groove 15 that cooperates with the spray gun 4. A fixing plate 16 is rotatably mounted on the bottom of the mounting bracket 3 near the spray gun 4. A fixing bolt 17 is threadedly connected to the top of the fixing plate 16. A fixing hole 18 is provided on the top of the mounting bracket 3 near the fixing bolt 17. The fixing hole 18 cooperates with the fixing bolt 17.

[0021] One end of the top of the mounting groove 15 is connected to a groove 19, which cooperates with the injection tube 5.

[0022] The pushing mechanism includes an electric push rod 12, which is fixedly installed inside the mounting bracket 3. A push plate 13 is fixedly installed on the telescopic shaft end of the electric push rod 12. A connecting groove 14 is provided at the end of the push plate 13 away from the electric push rod 12. The connecting groove 14 cooperates with the circular plate 11.

[0023] A connecting plate 20 is fixedly installed on the bottom of the drone body 1. A rotary motor 21 is fixedly installed on the side of the connecting plate 20 away from the mounting bracket 3. The output shaft end of the rotary motor 21 is fixedly connected to the mounting bracket 3.

[0024] Working principle: In use, first rotate the sealing cap 6, remove the sealing cap 6, pour the pigment into the spray tube 4 through the injection tube 5, then install the sealing cap 6 on the outside of the injection tube 5, then place the spray tube 4 in the mounting groove 15 and place the injection tube 5 in the groove 19, while making the circular plate 11 in the connecting groove 14, and finally rotate the fixing plate 16 and rotate the fixing bolt 17 so that the fixing bolt 17 is inserted into the fixing hole 18, thus fixing the spray tube 4 to the mounting bracket 3. By setting the connection between the spray tube 4 and the mounting bracket 3 to be detachable, it is convenient to add pigment into the spray tube 4 or replace the spray tube 4 in the future. Staff members control the drone body 1 to fly and use the survey camera 2 to survey the slope rock mass. When the target location is found, the electric push rod 12 is activated, which drives the push plate 13 to move synchronously. As the push plate 13 moves, the circular plate 11, the push rod 10 and the piston 9 move synchronously. At this time, the one-way valve 8 opens, and the pigment inside the spray gun 4 can be sprayed through the nozzle 7 to the target location for marking. This makes it convenient for subsequent staff to quickly determine the target location without having to check with the location observed by the drone, thus shortening the verification time for subsequent staff. The rotary motor 21, once started, can drive the mounting bracket 3 and the spraying cylinder 4 to rotate synchronously, thereby adjusting the angle at which the paint is sprayed from the spraying cylinder 4 and improving the accuracy of marking the target position.
