Description

Technical Field

[0001] The utility model is a high-rise building exterior wall tethered cleaning drone, which relates to the technical field of drones. Background Art

[0002] The cleaning of the exterior walls of high-rise buildings is an emerging industry that has grown in modern cities for the overall beauty of the city. At present, most of them are cleaned manually. The people engaged in this industry are professionally trained high-altitude operators who use high-altitude operating ropes, safety ropes, and high-altitude sitting boards (or hanging boards, hanging baskets, etc.) to scrub the exterior wall materials of the building from top to bottom to clean the cleaning agents and dirt and dust. These high-altitude operators need to rely on the hanging ropes for a long time when working, so this work has high requirements on the physical fitness of practitioners and the natural climate when working; in order to reduce the physical burden on practitioners as much as possible and improve work safety, the relevant industry has come up with a variety of solutions such as sling tracks and hanging baskets; but even so, the cleaning efficiency is not high, and accidents still occur frequently. It can be said that it is an extremely dangerous job, but we must need this group of practitioners; for this, we have launched a high-rise exterior wall cleaning drone, and the existing drone structure and function are relatively simple. It is just a simple control of takeoff to drive the water pipe to spray water, and it cannot control the water spraying effect. The spraying effect on the exterior wall is poor, and the drone is not stable enough when used, so it is necessary to propose a high-rise exterior wall tethered cleaning drone. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a tethered cleaning drone for the exterior walls of high-rise buildings to solve the problems mentioned in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a high-rise building exterior wall tethered cleaning drone, comprising a body and a tripod arranged at the bottom of the body, and a four-axis eight-propeller power structure is arranged on four sides of the body;

[0005] A high-pressure water spray device is mounted on the belly of the bottom of the fuselage;

[0006] The high-pressure water spraying device includes a water spraying pipe gun and a mounting frame for mounting the water spraying pipe gun, the mounting frame is fixedly mounted on the bottom of the machine body, and the machine body is equipped with a high-pressure water pump connected to one end of the water spraying pipe gun;

[0007] A rotating pressure regulating sleeve is rotatably provided on the side of the water spray gun away from the high-pressure water pump, a first diagonal water blocking plate is integrally provided on the water outlet of the water spray gun, a second diagonal water blocking plate is fixedly provided on the side of the rotating pressure regulating sleeve close to the water outlet of the water spray gun, and the second diagonal water blocking plate is closely attached to the front side of the first diagonal water blocking plate;

[0008] The first diagonal water blocking plate and the second diagonal water blocking plate are both provided with interconnected water outlets in the middle.

[0009] A further improvement is that a driven gear is fixedly arranged on the outer side of the rotating voltage regulating sleeve, a driving motor is installed at the bottom of the installation frame, and a driving gear meshing with the driven gear is installed at the shaft end of the driving motor.

[0010] A further improvement is that the water inlet end of the high-pressure water pump is connected to a moored water supply pipe, and is externally connected to a cleaning liquid tank through the moored water supply pipe.

[0011] A mooring power supply box is arranged inside the machine body, and one side of the mooring power supply box is connected with a mooring cable.

[0012] A further improvement is that a front obstacle avoidance radar and a forward-looking single-axis FPV are installed on the front side of the fuselage, and a downward-looking visual sensor is installed on the rear side of the fuselage.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] The utility model adds a high-pressure water spraying device, which uses a high-pressure water pump to pump water and increase the pressure, and the water spraying gun sprays water. At the same time, the driving motor can drive the active gear to mesh with the driven gear, so that the rotating pressure regulating sleeve sleeved on the outside of the water spraying gun rotates, so that the second diagonal water blocking plate rotates on the outside of the first diagonal water blocking plate, thereby adjusting the size of the water outlet of the water spraying gun, adjusting the water pressure and range of the water spraying gun, and can be flexibly used according to usage requirements to improve the external wall spraying effect; and the UAV is made of carbon fiber material, which can reduce the weight of the UAV without changing the appearance structure of the UAV, improve the performance and endurance of the UAV, and add a front obstacle avoidance radar and a downward visual sensor for technical integration, so as to improve the obstacle avoidance capability and environmental perception accuracy of the UAV, which has a more positive and beneficial use effect than the existing technology.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 6 The utility model provides a technical solution for a tethered cleaning drone for high-rise exterior walls: comprising a body 1 and a tripod 2 arranged at the bottom of the body 1, and a four-axis eight-propeller power structure 4 is arranged on four sides of the body 1; the four-axis eight-propeller drone is very suitable for performing tasks in complex environments due to its excellent controllability and stability, and can improve flight stability;

[0025] A high-pressure water spray device 9 is mounted on the belly of the bottom of the machine body 1. The high-pressure water spray device 9 includes a water spray pipe gun 92 and a mounting frame 91 for mounting the water spray pipe gun 92. The mounting frame 91 is fixedly mounted on the bottom of the machine body 1. The machine body 1 is equipped with a high-pressure water pump 90 connected to one end of the water spray pipe gun 92. The ground water tank is pressurized and pumped by the high-pressure water pump 90, and water is sprayed out by the water spray pipe gun 92. A rotating pressure regulating sleeve 93 is provided on the side of the water spray pipe gun 92 away from the high-pressure water pump 90. The water outlet of the water spray pipe gun 92 is integrally provided with a first diagonal water blocking plate 11. The rotating pressure regulating sleeve 93 is provided with a rotating pressure regulating sleeve 93. A second diagonal water blocking plate 12 is fixedly provided on one side of 93 near the water outlet of the water spraying pipe gun 92, and the second diagonal water blocking plate 12 is closely attached to the front side of the first diagonal water blocking plate 11. Therefore, the pressure regulating sleeve 93 is rotated to make the second diagonal water blocking plate 12 overlap with the first diagonal water blocking plate 12. At this time, the water outlet of the water spraying pipe gun 92 is the largest. When the second diagonal water blocking plate 12 gradually rotates to stagger the first diagonal water blocking plate 11, it will gradually block the water outlet of the water spraying pipe gun 92, thereby reducing the size of the water outlet. Therefore, rotating the pressure regulating sleeve 93 can adjust the size of the water outlet of the water spraying pipe gun 92 and the water spraying range.

[0026] Specifically, when the water outlet of the water spray gun 92 is small and has a small diameter, the speed of the water flow will increase, and a higher water pressure can be generated through the smaller opening, and the higher water pressure means that the water can be sprayed farther from the water spray gun 92 and has a stronger impact force when hitting the outer wall, which is conducive to improving the spraying effect on the outer wall;

[0027] On the contrary, when the water outlet of the water spray gun 92 is larger, the water flow rate will decrease and the water pressure will decrease accordingly. The larger water outlet allows more water to flow out at the same time, increasing the flow rate. This has a relatively large water spray range on the wall and can be adjusted according to the use requirements.

[0028] In addition, the first diagonal water blocking plate 11 and the second diagonal water blocking plate 12 are both provided with interconnected water outlets 13 in the middle to ensure that the water flow channel is not blocked. The water spraying pipe gun 92 always has the effect of spraying water. When the water flows only through the water outlet 13 for spraying, the water pressure is the highest.

[0029] In order to realize the rotation of the above-mentioned rotating pressure regulating sleeve 93, a driven gear 94 is fixedly provided on the outer side of the rotating pressure regulating sleeve 93, a driving motor 95 is installed at the bottom of the mounting frame 91, and a driving gear 96 meshing with the driven gear 94 is installed on the shaft end of the driving motor 95. The driven gear 94 is driven by the driving motor 95, so that the driving gear 96 meshing with the driven gear 94 rotates, thereby driving the rotating pressure regulating sleeve 93 to rotate on the outer side of the water spray pipe gun 92, so as to realize the adjustment of the water outlet size of the above-mentioned water spray pipe gun 92.

[0030] In this embodiment, the water inlet end of the high-pressure water pump 90 is connected to a tethered water supply pipe 10, and water is supplied to an external cleaning liquid tank through the tethered water supply pipe 10. A tethered power supply box 5 is provided inside the body 1, and one side of the tethered power supply box 5 is connected to a tethered cable 51, which is powered by an external ground power supply through the tethered cable 51.

[0031] In addition, the UAV adopts a four-axis eight-propeller power structure 4 for flight. The four-axis eight-propeller design is an application of existing technology, which can improve the stability and maneuverability of the flight. Each propeller can be controlled independently. By adjusting the rotation speed of each propeller, the UAV can accurately control the flight direction and attitude, achieve stable hovering, vertical take-off and landing, and rapid turning. If one of the propellers fails or is damaged, the other propellers can still maintain the flight of the UAV, so that it can automatically adjust its attitude and land safely, thereby improving the stability of use. A front obstacle avoidance radar 6 and a forward-looking single-axis FPV 7 are installed on the front side of the body 1, and a downward-looking visual sensor 8 is installed on the rear side of the body 1. The coordinated use of the front obstacle avoidance radar 6 and the downward-looking visual sensor 8 can improve the obstacle avoidance capability and environmental perception accuracy of the UAV.

[0032] Furthermore, the drone body 1 is made of carbon fiber material, which can reduce the weight of the drone without changing the appearance and structure of the drone, and improve the performance and flight time of the drone.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
