Description

Technical Field

[0001] This utility model relates to the field of water collection equipment for drones, and in particular to an automatic water collection device for drones used for water quality monitoring. Background Technology

[0002] With the increasing demand for water environment monitoring and watershed water quality management, traditional water quality sampling relies on manual boating, on-site excavation, or collection at fixed monitoring points, which is difficult to cover remote waters, pollution-prone areas, or large watersheds. It suffers from low sampling efficiency, poor operational safety, limited coverage, and high labor costs. Meanwhile, drones, with their advantages of high mobility, wide coverage, and ability to quickly reach complex waters, are gradually becoming an important carrier for water quality monitoring. Existing drone-based water sampling devices have significant drawbacks: First, the sampling process is unstable. The existing devices lack effective positioning and protection structures during the extension and retraction of the pull rope, making them susceptible to displacement due to airflow and device vibration, leading to tank tilting or even overturning. Furthermore, the pull rope and guide components often rely on sliding friction, which can cause wear and breakage over time, shortening the device's lifespan and increasing maintenance costs. Second, the water sample sealing and collection effects are poor. The inlet sealing design of existing devices is unreasonable, and some devices do not consider the internal air pressure, preventing air from escaping during sampling and obstructing water flow. This results in insufficient sample collection or inaccurate sample concentration, affecting test results. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic water-collecting device for water quality monitoring drones.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatic water-collecting device for a water quality monitoring drone, comprising a transmission box installed on the bottom surface of the drone, a positioning cover installed on the bottom surface of the transmission box, and a guide hole opened in the middle of the bottom surface of the transmission box, and a water-collecting component inside the transmission box.

[0005] Preferably, the water intake assembly includes a motor installed inside the transmission box, and a take-up roller is mounted on the output shaft of the motor via a coupling. A pull rope is wound around the outside of the take-up roller, and the outer end of the pull rope passes through a guide hole.

[0006] Preferably, multiple equidistant ball bearings are installed at both the upper and lower ends of the inner wall of the guide hole.

[0007] Preferably, the outer end of the pull rope is connected to a can lid, the top surface of the can lid has multiple equidistant vents, and the lower end of the can lid is fitted with a can body.

[0008] Preferably, a connecting frame is horizontally installed at the lower end of the inner wall of the tank, a spring is installed in the middle of the bottom surface of the connecting frame, and a foam block with a trapezoidal cross-section is installed at the lower end of the spring.

[0009] Preferably, the bottom surface of the tank is provided with a water inlet that mates with the foam block, and a sealing ring is installed on the upper end of the foam block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the cooperation between the positioning cover and the ball bearing prevents the tank from tilting due to deviation during the pulling rope's retraction and release, reduces rope wear and lowers the resistance during retraction and release, improves the stability of the device operation and the service life of the rope, thereby ensuring the stability of the tank's posture and smooth rope movement during water intake; the cooperation of the connecting frame, spring, foam block and sealing ring facilitates the foam block to float up under the buoyancy of the water during water intake, opening the water inlet and allowing the water sample to enter. After water intake, the spring returns to its original deformation, pushing the foam block to fit the water inlet, and the sealing ring further enhances the sealing effect, preventing water sample leakage from the tank, ensuring the integrity and purity of the water sample, thereby avoiding water sample loss or contamination, and providing a guarantee for the accuracy of water quality test results.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 5 The automatic water-collecting device for a water quality monitoring drone of this utility model includes a transmission box 1 installed on the bottom surface of the drone. A positioning cover 2 is installed on the bottom surface of the transmission box 1, and a guide hole is opened in the middle of the bottom surface of the transmission box 1. A water-collecting component is installed inside the transmission box 1. The transmission box 1 is designed to serve as the overall mounting base for the device and is fixed to the bottom surface of the drone. The positioning cover 2 is designed to prevent the pull rope 5 from shifting and causing the tank 8 to tilt. The water-collecting component includes a motor 3 installed inside the transmission box 1. The output shaft of the motor 3 is connected to a winding roller 4 via a coupling. A pull rope 5 is wound around the outside of the take-up roller 4, and the outer end of the pull rope 5 passes through the guide hole. The motor 3 facilitates the control of the rotation of the take-up roller 4, thereby realizing the lengthening and shortening of the pull rope 5. The take-up roller 4 facilitates the conversion of the rotational power of the motor 3 into the winding and unwinding action of the pull rope 5. The pull rope 5 facilitates the lifting and lowering of the tank body 8 as a whole, so that the tank body 8 can contact the water surface to complete the water intake. Multiple equidistant ball bearings 6 are installed on the upper and lower ends of the inner wall of the guide hole. The ball bearings 6 help to reduce the resistance and wear of the pull rope 5 during winding and unwinding, and extend the service life of the pull rope 5.

[0015] In this invention, the outer end of the pull rope 5 is connected to a can lid 7. The top surface of the can lid 7 has multiple equidistant vents, and a can body 8 is installed at the lower end of the can lid 7. The can lid 7 facilitates the transmission of power from the pull rope 5 to the can body 8. The can body 8 facilitates the collection of water samples when in contact with the water surface. A connecting frame 9 is horizontally installed at the lower end of the inner wall of the can body 8. A spring 10 is installed in the middle of the bottom surface of the connecting frame 9, and a trapezoidal foam block 11 is installed at the lower end of the spring 10. The connecting frame 9 provides a stable mounting support point for the spring 10. The position of the spring 10 is limited to prevent it from shifting when under force, ensuring the precise sealing action of the foam block 11. The spring 10 facilitates the foam block 11 to fit against the water inlet of the tank 8, achieving a water inlet seal. The bottom surface of the tank 8 has a water inlet that mates with the foam block 11, and a sealing ring 12 is installed on the upper end of the foam block 11. The foam block 11 facilitates the collection of water samples by the tank 8. The sealing ring 12 prevents water samples from leaking from the water inlet gap when not collecting water, ensuring the integrity and accuracy of water sample collection.

[0016] Working principle: When using this invention, firstly, the transmission box 1 is bolted to the bottom of the drone. Then, all electrical equipment is connected by wires and powered on. The drone is then started and flies over the sampling area. The motor 3 is started, and the motor 3 controls the winding roller 4 to unwind, thereby controlling the pull rope 5 to pull the tank 8 to contact the water surface. Then, the motor 3 is stopped. When the tank 8 contacts the water surface, the buoyancy of the water causes the foam block 11 to float upward. At this time, external water enters the tank 8 through the inlet and is released through the vent on the top of the tank cover 7. The air inside tank 8 is expelled to prevent excessive air pressure inside the tank from obstructing the water flow until tank 8 is filled with water sample. Then, motor 3 is started to reverse, thereby controlling the winding roller 4 to wind up the pull rope 5. The pull rope 5 pulls tank 8 upward, thereby controlling tank 8 to detach from the water surface. After detaching from the water surface, spring 10 restores its elastic deformation and pushes foam block 11 downward, so that foam block 11 re-fits the water inlet of tank 8. The sealing ring 12 at the upper end of foam block 11 further enhances the sealing effect to prevent water sample leakage from the tank. Then, the drone takes tank 8 back to base.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
