Description

Technical Field

[0001] The present invention belongs to the technical field of environmental protection equipment, and in particular relates to a protection equipment and a protection method based on a drone. Background Art

[0002] Drones are unmanned aircraft that are usually controlled by radio control equipment or self-contained programs and are used in a wide range of fields.

[0003] Environmental issues are a serious problem that my country has to face. In modern life, there is a lot of dust in the air, which mainly comes from road traffic, house construction or industrial manufacturing. For the treatment of dust in the air, sprinklers are usually used to adsorb the dust to a certain extent, but sprinklers have great limitations and have little effect on regional dust control. In the process of reducing dust, people often use more passive methods such as wearing protective equipment, such as masks and air purifiers, etc., but they can only protect a very small area. It is impossible to protect large residential areas or isolate the dust source. Summary of the invention

[0004] The purpose of the present invention is to provide a protective device and a protective method based on a drone, which is based on the use of a drone and utilizes water mist to continuously absorb and isolate dust in the environment, thereby regionally isolating industrial dust or road dust to protect the environment.

[0005] The object of the present invention is achieved in that:

[0006] A protective device based on a drone comprises a drone. A mounting frame is fixed at the bottom of the drone. A horizontal water collecting nozzle is fixed on the mounting frame. A plurality of spray holes are evenly distributed at the bottom of the water collecting nozzle. A water supply pipe is connected to the bottom of the water collecting nozzle. The other end of the water supply pipe is connected to a high-pressure water supply device. The drone is connected to a power supply and control device via a wire.

[0007] The present invention is further configured such that the mounting frame is a landing support frame for the UAV, the mounting frame is an inverted T-shaped structure, the two mounting frames are symmetrical with respect to the center and the bottoms are both inclined downward, a connecting piece is sleeved on the water collecting nozzle, a mounting hole for fixing the mounting frame is opened on the top of the connecting piece, and the aperture size of the mounting hole is adjusted by a bolt.

[0008] The present invention is further configured such that the high-pressure water supply device comprises a high-pressure water pump whose output end is connected to the water supply pipe, and whose input end is connected to a water storage tank.

[0009] The present invention is further configured such that one side of the water storage tank is connected to a water collection source, the water collection source includes a water seepage brick area laid below the water collection nozzle, a water collection pipeline is provided at the bottom of the water seepage brick area, and the water collection pipeline is connected to the water storage tank through a filter.

[0010] The present invention is further configured such that a plurality of spray hole assembly holes are provided at the bottom of the water collecting nozzle, a spray hole seat is detachably connected to the spray hole assembly hole, and a spray hole connected to the water collecting nozzle is provided in the spray hole seat.

[0011] A protection method based on drones. The above-mentioned protection equipment has corresponding water collection nozzles fixed on the bottom of several drones, and several water collection nozzles are continuously supplied with water using corresponding water supply pipes. Every 2-3 water supply pipes are connected to a high-pressure water supply device, and the water collection nozzles under two adjacent drones are located on the same straight line.

[0012] In the above method, the drones are arranged in double rows, and the two water-collecting nozzles of two adjacent rows are parallel to each other, thereby enhancing the partition effect; if the drones are arranged in a form of surrounding and enclosing a certain area, regional protection or partition can be achieved.

[0013] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0014] 1. The present invention is based on the free hanging form of the UAV, and the water collecting nozzle is hung. The high-pressure water supply device continuously provides high-pressure water to the water collecting nozzle, and finally sprays it out from the spray hole, forming an isolation wall with high-pressure water mist as a whole, thereby effectively providing dust blocking, and effectively improving the regional environmental protection effect.

[0015] 2. The mounting frame further provided by the present invention is the bottom landing support frame of the UAV, which adopts the structure of the UAV itself to reduce the damage to the balance of the UAV, effectively fixes the external water collection nozzle through the connecting parts, and uses bolts to tighten it after installation to enhance the connection strength.

[0016] 3. The high-pressure water supply device provided by the present invention adopts the form of connecting a water storage tank with a high-pressure water pump as a whole, so as to provide water spraying pressure for a water collection nozzle which is higher than the water storage tank, and achieve a water mist spraying effect. The fine water mist realizes a better dust isolation effect.

[0017] 4. The present invention further adopts a water collection source disposed on one side of the water storage tank, which can effectively collect the sprayed water mist to a certain extent, thereby circulating and performing long-term protective operations.

[0018] 5. The protection method provided by the present invention is to make multiple drones work simultaneously, and connect the water collection nozzles in two adjacent groups of drones to achieve a longer length of partition, thereby producing a regional partition effect; using two or more parallel drone groups can further enhance the partition protection effect.

[0026] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1 — Figure 2 :

[0027] A protective device based on a drone includes a drone 1. A mounting frame 10 is fixed at the bottom of the drone 1. A horizontal water collection nozzle 2 is fixed on the mounting frame 10. A plurality of spray holes 20 are evenly distributed at the bottom of the water collection nozzle 2. A water supply pipe 30 is connected to the bottom of the water collection nozzle 2. The other end of the water supply pipe 30 is connected to a high-pressure water supply device 3. The drone 1 is connected to a power supply and control device 4 via a wire 40.

[0028] And as Figure 2 As shown, the UAV is controlled by remote control or power supply and control device 4 to rise to a specific height, and the water collecting nozzle 2 connected to the high-pressure water supply device 3 is lifted up at the same time to spray high-pressure water continuously. After reaching a certain height, the fan-shaped mist surface sprayed by the nozzle will be further enlarged, but the content of water mist will also decrease towards the bottom.

[0029] Dust isolation in the spraying area can be achieved in the above-mentioned appropriate height range, thereby achieving completely different environmental effects on both sides of the spraying area.

[0030] In the drone used above, the parameter control variable requirements of the drone 1 are: the weight including the mounting frame 10 and the built-in battery is less than 7 kg; the maximum take-off weight is controlled to be less than 10 kg; the ascent speed is not less than 5 m / s; the maximum pitch angle is 30°; the maximum wind speed that can be tolerated is less than 15 m / s; it includes O3 image transmission industry version, six positioning obstacle avoidance, IP55; the battery capacity is not less than 6000 mAh, etc.

[0031] The main function of the power supply and control device is protection. Such as input overvoltage, undervoltage protection, output overvoltage, overcurrent, short circuit, short circuit, overtemperature protection, etc. The control part is to adjust the voltage, current, torque and other parameters in time through manual control. The power supply and control device is placed on the ground and manually controlled on the working ground.

[0032] Preferably, the mounting frame 10 is a ground support frame for the UAV 1, and the mounting frame 10 is an inverted T-shaped structure. The two mounting frames 10 are symmetrical with each other and the bottoms are both inclined downward. A connecting piece 21 is sleeved on the water collecting nozzle 2, and a mounting hole 210 for fixing the mounting frame 10 is opened on the top of the connecting piece 21, and the aperture size of the mounting hole 210 is adjusted by bolts.

[0033] In the above structure, the connecting member 21 has openings at both ends, and is fixedly connected to the mounting frame 10 and the water collecting nozzle 2 respectively, and a bolt is arranged on one side of the opening to control the size of the opening to adjust the locking degree. This adjustment form can slightly adjust the position of the water collecting nozzle 2 at the bottom of the drone and is beneficial to balance.

[0034] Preferably, the high-pressure water supply device 3 includes a high-pressure water pump 31 whose output end is connected to the water supply pipe 30 , and the input end of the high-pressure water pump 31 is connected to a water storage tank 32 .

[0035] Preferably, one side of the water storage tank 32 is connected to a water collection source, which includes a water seepage brick area laid below the water collection nozzle 2, and a water collection pipeline is provided at the bottom of the water seepage brick area, which is connected to the water storage tank through a filter. The use of the water seepage brick area is mainly used in areas where the bottom of the drone is relatively flat, and the overall ground is relatively flat, which is easy to lay water seepage bricks in the water seepage brick area. At the same time, the use of the filter is used to filter the adsorbed toxic substances or dust, so that the reused water resources will not affect the surrounding environment.

[0036] Preferably, a plurality of spray hole assembly holes are provided at the bottom of the water collection nozzle 2, and a spray hole seat is detachably connected to the spray hole assembly hole, and a spray hole connected to the water collection nozzle 2 is provided in the spray hole seat. With the above structure, spray holes of different specifications can be effectively replaced according to actual adjustment or maintenance requirements; the replacement of specifications changes the atomization effect, and also utilizes the adjustment of the height of the drone.

[0037] A protection method based on drones, wherein corresponding water collection nozzles 2 are fixed to the bottom of several drones 1, and the several water collection nozzles 2 are continuously supplied with water by corresponding water supply pipes 30. Every 2-3 water collection nozzles 2 are supplied with water by a high-pressure water supply device 3, and the water collection nozzles 2 under two adjacent drones 1 are located on the same straight line.

[0038] In the above protection method, in actual situations, the length of the wire is about 100 to 150 meters. It includes 80 to 100 meters of mooring lines and 50 to 70 meters of extension lines. In addition, the drone is equipped with a wire-retracting device with a torque of 0 to 10 Newtons and a wire-retracting speed of 0 to 2 meters per second for wire storage. Multiple groups of drones can take off one by one. After takeoff, the water-collecting nozzles at the bottom of adjacent drones are controlled to abut against each other, thereby achieving uninterrupted spraying area. The linear direction is separated in the above manner. If a surrounding form is adopted, a certain large area can be effectively protected.

[0039] Based on the application of this method, for areas with industrial pollution or large dust, a multi-row drone group is used for stronger protection. In addition, a mitigating agent is added to the water storage tank 32 in the high-pressure water supply device to reduce the emission and isolation of toxic gases.

[0040] In addition, during the implementation of multiple drone groups, the power supply and water supply requirements can be met by using multiple drones to share a power supply and control device 4 and a high-pressure water supply device, and the pressure of the high-pressure water pump can be adjusted according to actual needs to meet the water supply requirements of multiple water collection nozzles.

[0041] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
