Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) equipment, and more particularly to a highly stable UAV water collection device. Background Technology

[0002] In the application of drones for water collection, traditional water collection devices often adopt a structural design of "lifting rope + counterweight water bucket". This mode has many shortcomings in actual operation: First, the water bucket is prone to violent shaking when moving up and down, which directly interferes with the hovering stability of the drone. Especially in complex airflow environments in the wild, it is very easy for the drone to deviate from the water collection point, and even cause the risk of crashing. Second, a single water collection can only store one sample. If multiple water points need to be sampled, multiple take-offs and landings are required, which greatly increases the operation time and results in low water collection efficiency. Third, the change in the weight of the drone after water collection can easily cause the center of gravity to shift, further reducing flight stability. Therefore, we propose a drone water collection device with high stability to solve the above-mentioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by proposing a highly stable unmanned aerial vehicle (UAV) water collection device.

A connecting chamber is installed between the retaining rings via the knob, and a toothed groove is formed at the bottom of each connecting chamber. A base box is fixedly connected to the bottom of the connecting chamber, and a turntable is rotatably connected to the center of the bottom of the connecting chamber.

A counterweight tank is installed on the upper moving part of each electric slide rail, and the side of the counterweight tank closest to the storage tank is fixedly connected to... The device is equipped with conduits, the ends of which are furthest from the counterweight compartment are connected to the pump body inside the storage compartment. Servo motors are installed at the top ends of the electric slide rails, and the bottom drive shafts of the servo motors pass through the electric slide rails. Gear columns are fixedly connected to the bottom drive ends of the servo motors, and the gear columns are meshed with the inner sides of the gear grooves.

Controllers are installed in the middle of both sides of the connecting compartment.

[0005] Preferably, a fixing plate is installed in the middle of the bottom box, and a take-up roller is provided on the upper side of the middle of the bottom box. Both ends of the take-up roller are rotatably connected to fixing frames. The fixing frames are all installed in the upper middle of the bottom box. A through pipe passes through the middle of the fixing frame and passes through the middle of the take-up roller. A coil spring is provided on the inner side of the fixing frame. One end of the coil spring is connected to a coil spring, and the other end of the coil spring is connected to the through pipe.

[0006] Preferably, guide wheels are installed on both sides of the bottom center of the base box, and a stepper motor is installed on one side of the shaft of each guide wheel. The guide wheels are arranged on both sides of the water pumping pipe.

[0007] Preferably, each end of the through pipe is connected to a connecting pipe via a sealed bearing, and a pump set is fixedly connected to the end of the connecting pipe away from the through pipe. The pump sets are installed on both sides of the top of the fixed plate, and the output of each pump set is connected to a connecting hose and a drain pipe via a tap valve. A horizontal pipe is fixedly connected to the end of each connecting hose.

[0008] Preferably, an air pump is installed on one side of the outer circumference of the take-up roller, and a water pumping pipe is wound around the outer circumference of the air pump. One end of the water pumping pipe penetrates the side wall of the take-up roller, and evenly distributed connecting holes are opened on the outer circumference of the pipe. The ends of the water pumping pipe all penetrate the bottom of the bottom box.

[0009] Preferably, one end of the water pump pipe that penetrates the side wall of the take-up roller is connected to the inside of the through pipe through a connecting hole, and side channels are opened on both sides of the water pump pipe wall. The output end of the air pump is connected to the inside of the side channels through a connecting ring.

[0010] Preferably, a fixing sleeve is fixedly connected to both sides of the bottom of the horizontal tube, and a threaded rod is threadedly connected to the lower part of the fixing sleeve, and a stepper motor is fixedly connected to the bottom of the threaded rod.

[0011] Preferably, each stepper motor is fixedly connected to the bottom of the fixed plate, and each horizontal tube has multiple connecting caps connected to its bottom via a valve body, with a storage bottle provided at the bottom of each connecting cap.

[0012] Preferably, the storage bottles are all clamped to one side of the side frame by a row of clips, and a pull ring is installed in the middle of the outer side wall of each side frame. The side frames are all installed in the middle of the front and rear of the bottom box by a buckle.

[0013] Preferably, each drain pipe is fixedly connected to a drain chamber at its bottom, the drain chambers are installed on both sides of the bottom of the base box, and each drain chamber is equipped with a drain valve at its bottom.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this invention, when the drone flies to the designated water area, it first hovers above the water. Then, a stepper motor drives a guide wheel to rotate, which in turn loosens the water pipe, allowing it to be lowered. The stepper motor controls the rotation of the guide wheel, enabling control over the water pipe's depth, which is beneficial for water collection. Compared to the traditional method of using a rope and bucket, this method reduces the impact of bucket swaying on the drone's hovering during the ascent and descent, thus improving the drone's stability during hovering.

[0016] 2. When collecting water, people can start the pump set on one side. The pump set can use the connecting pipe and the through pipe to create negative pressure to draw water from the bottom. Then, the water can be guided into the corresponding storage bottle at the bottom of the horizontal pipe through the connecting hose for storage. After the remote-controlled drone moves the water, by switching different connecting hoses and connecting cap outlet channels, the water can be stored in different storage bottles. This allows the drone to collect and store water from different water areas in a single trip, thereby reducing the time spent on the return trip and greatly improving water collection efficiency.

[0017] 3. During actual water intake, when changing water intake locations, after the pump unit draws water, it can first guide the water into the drainage chamber through the tap valve and drain pipe. The extracted water can flush the water remaining in the previous pump pipe. After flushing for a period of time, the water from the new location can be guided into the new connecting hose and storage bottle through the tap valve to complete the water intake work in the new water area. This avoids the water remaining in the pump pipe during continuous water intake from interfering with the water extracted from the new location, which helps to maintain the "purity" of the extracted water.

[0018] 4. After the extracted water is stored in the storage bottle, the water inside the drainage chamber can be discharged through the drain valve at the bottom of the drainage chamber. This avoids increasing the weight of the drone and causing it to become unbalanced. It also prevents direct drainage from causing "contamination" of the water to be extracted from the bottom water area, which would affect the "purity" of the subsequent wastewater and is beneficial for practical use.

[0019] 5. After water is drawn, the coil spring can drive the winding roller to reset and rotate. Under the action of the winding device, the water pipe can be rewound and reset, which facilitates subsequent water drawing. When drawing water, the air pump can be started at the same time when the water pipe is lowered. The operation of the air pump can introduce gas into the side channel through the connecting ring. The continuous introduction of gas will continuously increase the pressure inside the side channel, thereby keeping the water pipe lowered at the bottom vertical and preventing the water pipe from bending during winding, which would affect the accuracy of the lowering depth and facilitate precise water drawing.

[0020] 6. During water collection and flight, the internal level sensor detects the drone's horizontal balance and transmits the data to the controller. The controller then activates the electric slide rail and servo motor. The electric slide rail moves the counterweight compartment, and the servo motor rotates the gear column. This rotation causes the electric slide rail and counterweight compartment to deflect, thus adjusting the center of gravity of the connecting compartment and the drone. This further improves the drone's stability during water collection and flight. Simultaneously, the pump inside the storage compartment uses conduits to input and output water to the counterweight compartments on both sides, adjusting the weight of the counterweight compartments. This further enhances the drone's center of gravity adjustment effect and range, which is beneficial for practical use. Attached Figure Description

[0031] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0032] like Figures 1-9 The device shown is a highly stable UAV water collection device, comprising a body 101. Clamping rings 110 are installed on the front and rear sides of the bottom of the body 101. A knob 109 is threadedly connected to the center of each clamping ring 110. A connecting chamber 111 is installed between the clamping rings 110 via the knobs 109. A toothed groove 118 is formed at the bottom of the connecting chamber 111. A base box 108 is fixedly connected to the bottom of the connecting chamber 111. A turntable 122 is rotatably connected to the center of the bottom of the connecting chamber 111. A storage tank 121 is installed on the top of the turntable 122. Electric slide rails 123 are rotatably connected to the center of both sides of the turntable 122 via hinges. A counterweight tank 119 is installed on the upper moving part of each electric slide rail 123. A conduit 120 is fixedly connected to the side of the counterweight tank 119 closest to the storage tank 121. The end of pipe 120 away from counterweight chamber 119 is connected to the pump body inside storage chamber 121. Servo motors 116 are installed at the top and end of electric slide rail 123. The drive shafts of servo motors 116 at the bottom of electric slide rail 123 are all through electric slide rail 123. The drive ends of servo motors 116 at the bottom are all fixedly connected to gear columns 124. Gear columns 124 are all meshed with the inside of gear grooves 118. Multiple fixed rods 102 are installed on the outer periphery of body 101 through joint motors. Rotors 103 are installed at the ends of fixed rods 102. Drive motors are installed at the bottom of rotors 103. Support rods 105 are installed on both sides of the bottom of body 101 through joint motors. Support legs 104 are fixedly connected to the bottom of support rods 105. Controllers 112 are installed in the middle of both sides of connecting chamber 111.

[0033] Furthermore, in practical implementation, people can use a water-collecting drone to collect water. Before operation, the base box 108 is installed on the bottom of the body 101 using knob 109. Then, the drone can be remotely controlled via a remote controller. The drive motor rotates the rotor 103, which disturbs the airflow to provide lift for the drone, enabling it to fly. Adjusting the rotation speed and yaw direction of the rotor 103 controls the drone's flight direction and speed. During water collection and flight, a level sensor inside the body 101 detects the drone's horizontal balance and transmits the monitoring data to the controller 11. 2. The controller 112 can activate the electric slide rail 123 and the servo motor 116. The electric slide rail 123 can move the counterweight chamber 119, and the servo motor 116 can rotate the gear column 124. The rotation of the gear column 124 can deflect the electric slide rail 123 and the counterweight chamber 119, thereby adjusting the center of gravity of the connecting chamber 111 and the drone. This can further improve the stability of the drone when taking water and flying. At the same time, the pump inside the storage chamber 121 can input and output water into the counterweight chambers 119 on both sides through the conduit 120, thereby adjusting the weight of the counterweight chamber 119. This can further improve the center of gravity adjustment effect and adjustment range of the drone, which is beneficial to practical use.

[0034] Among them, the end of the water pumping pipe 127 passes through the bottom of the bottom box 108. Guide wheels 143 are installed on both sides of the bottom middle part of the bottom box 108. Stepper motor 139 is installed on one side of the shaft of the guide wheel 143. The guide wheels 143 are all located on both sides of the water pumping pipe 127.

[0035] Furthermore, in specific implementation, when the drone flies to the designated water area, it first hovers above the water. Then, people can drive the guide wheel 143 to rotate via the stepper motor 139. The guide wheel 143 can then loosen the water pipe 127, allowing it to be lowered. By controlling the rotation of the guide wheel 143 via the stepper motor 139, the depth of the water pipe 127 in the water can be controlled, which is beneficial for water collection.

[0036] The base box 108 has a fixing plate 113 installed in the middle. A take-up roller 132 is installed on the upper side of the middle of the base box 108. Both ends of the take-up roller 132 are rotatably connected to fixing frames 133. The fixing frames 133 are all installed in the upper middle of the base box 108. A through-tube 141 passes through the middle of each fixing frame 133, penetrating the middle of the take-up roller 132. A coil spring 140 is installed inside each fixing frame 133. One end of each coil spring 140 is connected to the coil spring 140, and the other end is connected to the through-tube 141. The outer circumference of the take-up roller 132 is... An air pump 117 is installed, and a water pump pipe 127 is wound around the outer periphery of the air pump 117 housing. A wire straightener is provided in the middle of one side of the water pump pipe 127. One end of the water pump pipe 127 passes through the side wall of the take-up roller 132. A connecting pipe 141 has evenly distributed connecting holes 129 on one side of its outer periphery. The end of the water pump pipe 127 that passes through the side wall of the take-up roller 132 is connected to the inside of the connecting pipe 141 through the connecting holes 129. Side channels 114 are provided on both sides of the wall of the water pump pipe 127. The output end of the air pump 117 is connected to the inside of the side channels 114 through the connecting ring 134.

[0037] Furthermore, in specific implementation, when taking water, the air pump 117 can be started simultaneously when lowering the water pipe 127. The operation of the air pump 117 can introduce gas into the side channel 114 through the connecting ring 134. The continuous introduction of gas will continuously increase the pressure inside the side channel 114, thereby keeping the lowered water pipe 127 vertical and preventing the water pipe 127 from bending during winding, which would affect the accuracy of the lowering depth and facilitate precise water taking. After taking water, the coil spring 140 can drive the winding roller 132 to reset and rotate. Under the action of the winding device, the water pipe 127 can be rewound and reset, which is convenient for subsequent water taking.

[0038] Each end of the through pipe 141 is connected to a connecting pipe 128 via a sealed bearing. A pump unit 126 is fixedly connected to the end of each connecting pipe 128 away from the through pipe 141. Pump units 126 are mounted on both sides of the top of the fixed plate 113. The output of each pump unit 126 is connected to a connecting hose 131 and a drain pipe 136 via a tap valve. A horizontal pipe 125 is fixedly connected to the end of each connecting hose 131. Fixed sleeves 135 are fixedly connected to both sides of the bottom of each horizontal pipe 125. A threaded rod 142 is threadedly connected to the lower part of each fixed sleeve 135. A stepper motor is fixedly connected to the bottom of each threaded rod 142. 137, stepper motor 137 is fixedly connected to the bottom of fixed plate 113, the bottom of horizontal tube 125 is connected to multiple connecting caps 130 through valve body, the bottom of connecting cap 130 is provided with storage bottle 144, the storage bottle 144 is snapped to one side of side frame 107 by clamp 138, the middle of the outer wall of side frame 107 is installed with pull ring 106, the side frame 107 is installed in the front and rear middle of bottom box 108 by buckle, the bottom of drain pipe 136 is fixedly connected to drain chamber 115, the drain chamber 115 is installed on both sides of the bottom of bottom box 108, and the bottom of drain chamber 115 is installed with drain valve;

[0039] Furthermore, in practical implementation, when collecting water, people can activate the pump set 126 on one side. The operation of the pump set 126 utilizes the connecting pipe 128 and the through pipe 141 to create negative pressure suction on the water extraction pipe 127, thereby extracting water from the bottom. Then, through the connecting hose 131, the extracted water can be guided into the corresponding storage bottle 144 at the bottom of the horizontal pipe 125 for storage. After the remote-controlled drone moves the water source, by switching different connecting hoses 131 and the outlet channels of the connecting cap 130, the water can be stored in different storage bottles 144. This allows the drone to extract and store water from different locations within a single trip, reducing the time spent on the return trip and significantly improving water collection efficiency. In actual water collection, when changing water collection locations, the pump set 126... After pumping water, the water can be introduced into the drainage chamber 115 through the tap valve and drain pipe 136. The pumped water can flush the water remaining in the previous pump pipe 127. After flushing for a period of time, the water from the new location can be introduced into the new connecting hose 131 and storage bottle 144 through the tap valve to complete the water collection work in the new water area. This avoids the water remaining in the pump pipe 127 from interfering with the water collected from the new location during continuous water collection, which helps to maintain the "purity" of the collected water. After the pumped water is stored in the storage bottle 144, the water in the drainage chamber 115 can be discharged through the drain valve at the bottom of the drainage chamber 115. This avoids increasing the weight of the drone and causing it to become unbalanced. It also avoids "contamination" of the water to be pumped from the bottom water area by direct drainage, which is beneficial for practical use.

[0040] Working principle:

[0041] In practical use, people can use the water-collecting drone to collect water. Before starting work, people can first install the base box 108 on the bottom of the body 101 using the knob 109. Then, the drone can be remotely controlled using the remote controller. The drive motor drives the rotor 103 to rotate, and the rotation of the rotor 103 can disturb the airflow to provide lift for the drone, thus enabling it to fly. By adjusting the rotation speed and yaw direction of the rotor 103, the flight direction and speed of the drone can be controlled. When collecting water, when the drone flies to the designated water area, it first hovers above the water. Then, people can drive the guide wheel 14 using the stepper motor 139. 3. Rotation of the guide wheel 143 loosens the water pipe 127, allowing it to be lowered. The rotation of the guide wheel 143, controlled by the stepper motor 139, controls the water depth of the water pipe 127, facilitating water collection. During water collection, the pump unit 126 on one side is activated. The pump unit 126 uses the connecting pipe 128 and the through pipe 141 to create negative pressure suction in the water pipe 127, extracting water from the bottom. The extracted water is then guided through the connecting hose 131 into the corresponding storage bottle 144 at the bottom of the horizontal pipe 125 for storage. After the drone moves the water, different connecting hoses 131 and the outlet channels of the connecting cap 130 can be switched. The system allows water to be stored in different storage bottles 144, enabling the drone to extract and store water from different locations within a single trip. This reduces return trip time and significantly improves water collection efficiency. During actual water collection, when changing locations, after pumping water using pump unit 126, the water is first directed to the drainage chamber 115 via a tap valve and drain pipe 136. The extracted water flushes out any residual water in the previous pump pipe 127. After flushing for a period, the tap valve then directs the water from the new location to a new connecting hose 131 and storage bottle 144, completing the water collection from the new location. This prevents residual water in the pump pipe 127 from affecting the water collected from the new location during continuous water collection. This design helps maintain the "purity" of the collected water. After the extracted water is stored in the storage bottle 144, the water in the drainage chamber 115 can be drained through the drain valve at the bottom of the drainage chamber 115, avoiding increasing the drone's weight and preventing it from becoming unbalanced. It also prevents direct drainage from contaminating the water to be extracted from the bottom water area, which is beneficial for practical use. After water extraction, the coil spring 140 drives the winding roller 132 to reset and rotate. The winding device allows the water extraction pipe 127 to be rewound and reset, facilitating subsequent water extraction. When extracting water, the air pump 117 can be started simultaneously when lowering the water extraction pipe 127. The air pump 117 introduces air into the side channel 114 via the connecting ring 134.The continuous intake of gas increases the pressure inside the side channel 114, keeping the lowered water pipe 127 vertical and preventing it from bending during winding, which would affect the accuracy of the lowering depth. This facilitates precise water collection. During water collection and flight, the horizontal sensor inside the fuselage 101 detects the drone's horizontal balance and transmits the data to the controller 112. The controller 112 then activates the electric slide rail 123 and servo motor 116. The electric slide rail 123 moves the counterweight chamber 119. The servo motor 116 drives the gear column 124 to rotate. This rotation of the gear column 124 causes the electric slide rail 123 and the counterweight chamber 119 to deflect, thereby adjusting the center of gravity of the connecting chamber 111 and the drone. This further improves the stability of the drone during water intake and flight. Simultaneously, the pump inside the storage chamber 121 uses conduits 120 to input and output water into the counterweight chambers 119 on both sides, allowing for weight adjustment of the counterweight chambers 119. This further enhances the effectiveness and range of center of gravity adjustment for the drone, which is beneficial for practical use.
