Description

Technical Field

[0001] This utility model belongs to the field of smart water conservancy technology, specifically relating to a buoy device for intelligent monitoring of the radiation range of self-supplied water sources in irrigation areas. Background Technology

[0002] Irrigation districts typically have numerous self-supplied water sources with unclear distribution ranges. Accurately measuring the coverage area of ​​these water sources is crucial for meeting both economic and ecological requirements, thus creating significant application demand. Currently, commonly used buoys are... Figure 4 The structure shown has poor flow characteristics during the experiment of measuring the radiation range of self-supplied water sources in irrigation areas. Therefore, there is a lack of metering facilities for measuring the radiation range of self-supplied water sources in irrigation areas. Utility Model Content

[0003] Based on the characteristics of self-supplied water sources in irrigation districts, this utility model provides a buoy device with good flow characteristics under low Frod number water flow conditions, which can be used for intelligent monitoring of the radiation range of self-supplied water sources in irrigation districts.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A buoy device for intelligent monitoring of the radiation range of self-supplied water sources in irrigation areas includes a hollow hemispherical floating ball, a floating plate connected to the top of the floating ball, the outer diameter of the floating plate being larger than the diameter of the floating ball, a GPS module installed inside the floating ball and fixed to the lower surface of the floating plate; four partitions are fixedly connected to the outside of the floating ball, the four partitions are connected in a cross shape to the circumferential surface of the outer shell of the floating ball, the four partitions have the same structure, and the end fixed to the outer shell of the floating ball is an arc surface.

[0006] Experiments have shown that a cross-shaped connection between the baffle and the outer shell of the floating ball improves the device's flow characteristics and enhances its flow performance.

[0007] As it flows with the water, GPS modules with different functions can be installed according to usage requirements, such as positioning the buoy device and transmitting the positioning data to the cloud platform. It can achieve a positioning accuracy of ≤0.5 meters at a depth of 10cm underwater, and supports NB-IoT low-power communication. In PSM mode, the static current is less than 5 microamps.

[0008] Furthermore, a connecting plate and a fixing plate are connected sequentially from bottom to top on the upper surface of the floating plate. The floating plate, connecting plate, and fixing plate are all circular ring structures, and the joints are all sealed and waterproof. A magnetic wireless charging module is installed in the center hole of the fixing plate. The outer diameter of the magnetic wireless charging module is the same as the center hole diameter of the fixing plate, and the magnetic wireless charging module is sealed to the fixing plate.

[0009] The magnetic wireless charging module is made of composite material and has a certain magnetic attraction. During recycling, the magnetic wireless charging module can be magnetically attracted by drones or manual operation, which facilitates the recycling of the device and realizes magnetic recycling technology, that is, the capture and recycling of target objects based on the principle of magnetic adsorption.

[0010] Furthermore, a lithium battery is installed inside the floating ball, and the lithium battery is connected to the magnetic wireless charging module and the GPS module via wires.

[0011] The GPS module can be attached to the inner surface of the floating board with an adhesive material and is continuously powered by a lithium battery via wires.

[0012] Furthermore, the lithium battery is spherical and not fixedly connected within the inner shell of the floating sphere. The spherical lithium battery adopts a self-stabilizing counterweight structure design, placed inside the floating sphere, and can swing freely with the movement of the device, thereby ensuring that the device maintains dynamic balance under the impact of water flow through a center of mass adjustment mechanism.

[0013] When measuring the radiation range of the irrigation district's self-supplied water source, a large number of cross-shaped floating positioning balls are thrown into the irrigation water source. Taking advantage of the good flow-following properties of the floating objects, after a certain period of time, the radiation range of the irrigation district's self-supplied water source can be obtained by receiving the coordinate position points and movement trajectories of the device, which can then be used to estimate the actual water demand of the irrigation district.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention designs the outer shell of the floating ball as a spherical shell with a cross-shaped partition, which improves the float's ability to follow the current; the design of the magnetic wireless charging module makes the device easy to retrieve; and the design of the spherical lithium battery inside the floating ball improves the device's stability.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, a buoy device for intelligent monitoring of the radiation range of self-supplied water sources in irrigation areas includes: a hemispherical floating ball 5, which is hollow inside. A floating plate 4 is connected to the top opening of the floating ball. A connecting plate 3 and a fixing plate 2 are connected sequentially from bottom to top on the upper surface of the floating plate. All connections are sealed and waterproof. The three-layer design forms a stepped load-bearing structure. The floating plate bears the main buoyancy, the connecting plate realizes the force transmission transition, and the fixing plate provides a rigid support platform. This multi-layer structure prolongs the attitude stability time of the buoy under water flow disturbance. This structure can effectively disperse the impact stress of water flow and reduce the risk of structural deformation. The floating plate 4, connecting plate 3, and fixing plate 2 are all ring structures. A magnetic wireless charging module 1 is installed in the central hole of the fixing plate 2. The outer diameter of the magnetic wireless charging module is the same as the central hole diameter of the fixing plate 2. The magnetic wireless charging module is sealed to the fixing plate 2. A GPS module 6 and a spherical lithium battery 7 are installed inside the floating ball. The GPS module 6 is fixed to the lower surface of the floating plate 4, and the spherical lithium battery 7 is not fixedly connected to the inner shell of the floating ball.

[0023] The spherical lithium battery is connected to the magnetic wireless charging module 1 via wire 1 9. The magnetic wireless charging module 1 charges the spherical lithium battery. The spherical lithium battery is connected to the GPS module 6 via wire 2 11. The length of the wires is designed so as not to hinder the rotation of the spherical lithium battery in the inner shell of the floating ball. The spherical lithium battery supplies power to the GPS module.

[0024] like Figure 3 As shown, four partitions 8 are fixedly connected to the outside of the floating ball 5. The four partitions are connected to the outer shell of the floating ball in a cross shape. The four partitions have the same structure, and the end that is fixed to the outer shell of the floating ball is an arc surface.

[0025] The Frod number of water flow in irrigation districts with their own water sources is generally less than 0.2, that is... F r <0.2, as proven by indoor water tank experiments and field experiments, in F r Under conditions of <0.2, the flow following coefficient of the buoy device described in this application is less than 1%, indicating that the device has good flow following performance under low Frod number flow conditions. Under the same experimental flow conditions, Figure 4 The flow coefficient of the spherical floating ball shown is about 7%, indicating that compared with the floating ball with a spherical shell, this device has better flow characteristics and is more suitable for the water flow structure and flow pattern of the irrigation area's self-supplied water source.

[0026] The following formula characterizes the flow behavior:

[0027]

[0028] Where δ is the flowability coefficient, which represents the flowability; the smaller the value, the better the flowability. V 物 Indicates the moving speed of the buoy device; V 水 This indicates the velocity of the water flow.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
