Abstract
Description
Technical Field
[0001] This invention belongs to the field of precipitation monitoring technology, specifically a precipitation monitoring device with wind power generation function. Background Technology
[0002] Precipitation monitoring devices are instruments or systems used to measure precipitation in a certain area over a certain period of time. They are widely used in meteorology, hydrology, agriculture, disaster prevention and mitigation and other fields.
[0003] Traditional monitoring devices (such as tipping bucket rain gauges) that rely on solar power suffer from insufficient power on cloudy or rainy days and require regular battery replacements, potentially incurring manual inspection costs in remote areas. Those relying on mains power require maintenance of power lines. Both scenarios increase long-term maintenance costs. Furthermore, mains power may be interrupted during extreme weather (such as heavy rain or typhoons) or in areas with weak power grids. During prolonged periods of cloudy or rainy weather, batteries may experience insufficient voltage due to low temperatures or short periods of sunlight, leading to missed or lost rainfall data. Therefore, improvements are needed to add a power supply backup function. Summary of the Invention
[0004] The purpose of this invention is to provide a precipitation monitoring device with wind power generation function, thereby providing an additional guarantee function for precipitation data monitoring and solving the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a precipitation monitoring device with wind power generation function, comprising a tipping bucket rain gauge, an installation mechanism at the front end of the tipping bucket rain gauge, a wind power generation mechanism at the front end of the installation mechanism, the wind power generation mechanism comprising a housing, a slot inside the housing, a generator bolted inside the slot, a clutch bolted at the front end of the generator, a brake disc bolted at the front end of the clutch, a gearbox bolted at the front end of the brake disc, a rotating shaft bolted at the front end of the gearbox, a bearing bolted at the front end of the rotating shaft, a hub located on the front side of the housing bolted at the front end of the bearing, and blades uniformly welded to the outer side of the hub.
[0006] Preferably, a protective shell is bolted to the rear side of the blade, a servo motor is bolted to the inside of the protective shell, a movable groove is opened inside the blade, a round shaft is rotatably installed inside the movable groove, the output end of the servo motor is bolted to the rear side of the round shaft, and a fan-shaped plate is fixedly sleeved on the outer side of the round shaft.
[0007] Preferably, the mounting mechanism includes a mounting base bolted to the front end of the tipping bucket rain gauge, the housing bolted to the front end of the mounting base, a lightning protection rod bolted to the top of the mounting base, and a grounding wire bolted to the bottom of the mounting base.
[0008] Preferably, in the initial state, the inner side of the fan-shaped plate and the outer side of the blade are located on the same horizontal plane.
[0009] Preferably, when the wind speed is too high, the fan-shaped plate is completely retracted into the interior of the movable slot.
[0010] Preferably, when the wheel hub rotates too fast, the brake disc brakes the gearbox.
[0011] Preferably, the lightning protection rod is electrically connected to the ground wire, and the bottom end of the ground wire extends into the ground.
[0012] Preferably, when the wind speed is too low, one end of the fan-shaped plate is disengaged from the interior of the movable groove, while the other end of the fan-shaped plate remains inside the movable groove.
[0013] The beneficial effects of this invention are as follows: 1. This invention utilizes a wind power generation mechanism to continuously generate and store electricity when wind is abundant, compensating for insufficient power from solar cells. In areas with prolonged periods of cloudy weather and insufficient sunlight, wind power generation is more stable than solar power, ensuring continuous operation and stable recording or transmission of precipitation data. Compared to traditional precipitation monitoring devices, this wind power-generated precipitation monitoring device requires no external power supply and is adaptable to harsh environments, making it highly practical.
[0014] 2. This invention can dynamically adjust the wind-receiving area of the blades through a servo motor and a fan-shaped plate to prevent strong winds from damaging the generator or tipping bucket rain gauge. At the same time, the clutch and brake disc can disconnect the power in extreme weather to protect the core components. Compared with traditional precipitation monitoring devices, this precipitation monitoring device with wind power generation function can effectively prevent the generator from being damaged by excessive wind speed by dynamically adjusting the wind-receiving area of the blades in conjunction with the clutch and brake disc.
[0015] 3. This invention effectively guides lightning through the combination of lightning protection rods and grounding wires, preventing damage to the equipment from lightning strikes; the metal casing provides additional electromagnetic shielding to protect the internal circuitry. Compared with traditional precipitation monitoring devices, this precipitation monitoring device with wind power generation function can effectively protect the tipping bucket rain gauge and wind power generation mechanism from lightning strikes through lightning protection rods and grounding wires, making it easy to use.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] like Figures 1 to 6 As shown, this embodiment of the invention provides a precipitation monitoring device with wind power generation function, including a tipping bucket rain gauge 1. An installation mechanism 2 is provided at the front end of the tipping bucket rain gauge 1. A wind power generation mechanism 3 is provided at the front end of the installation mechanism 2. The wind power generation mechanism 3 includes a housing 301. A slot 302 is opened inside the housing 301. A generator 303 is bolted inside the slot 302. A clutch 304 is bolted to the front end of the generator 303. A brake disc 305 is bolted to the front end of the clutch 304. A gearbox 306 is bolted to the front end of the brake disc 305. A rotating shaft 307 is bolted to the front end of the gearbox 306. A bearing 308 is bolted to the front end of the rotating shaft 307. A hub 309 located on the front side of the housing 301 is bolted to the front end of the bearing 308. Blades 310 are uniformly welded to the outer side of the hub 309.
[0020] The tipping bucket rain gauge 1 is fixed in a flat, open area, leveled to ensure measurement accuracy, and free from obstructions. It is grounded via ground wire 23. The lightning rod 22 is vertically installed above the mounting base 21 and connected to the lightning protection system. The housing 301 is installed on the side of the mounting base 21, with the slot 302 facing the prevailing wind direction. The connection between the blade 310 and the hub 309 is checked to ensure it is secure. Natural wind drives the blade 310 to rotate, which is then accelerated by the gearbox 306, thereby driving the generator 303 to generate electricity. The electrical energy is stored in the battery. When the wind speed is too high, the servo motor 313 pushes the fan-shaped plate 315 to cover the movable slot 311, reducing the wind-receiving area of the blade 310. If the wind speed still cannot be controlled, the clutch 304 disconnects the power transmission, and the brake disc 305 brakes the rotating shaft 307.
[0021] Wind power generation can continuously generate and store electricity when wind is plentiful, compensating for insufficient solar power. In areas with prolonged periods of cloudy weather and insufficient sunlight, wind power is more stable than solar power, ensuring continuous operation and stable recording or transmission of precipitation data. Compared to traditional precipitation monitoring devices, this wind-powered precipitation monitoring device requires no external power supply and is adaptable to harsh environments, making it highly practical.
[0022] like Figures 1 to 5 As shown, a protective shell 312 is bolted to the rear side of the blade 310, and a servo motor 313 is bolted inside the protective shell 312. A movable groove 311 is opened inside the blade 310, and a round shaft 314 is rotatably mounted inside the movable groove 311. The output end of the servo motor 313 is bolted to the rear side of the round shaft 314, and a fan-shaped plate 315 is fixedly sleeved on the outer side of the round shaft 314. When the wind speed is too high, the fan-shaped plate 315 is completely retracted into the movable groove 311. When the hub 309 rotates too fast, the brake disc 305 brakes the gearbox 306. When the wind speed is too low, one end of the fan-shaped plate 315 is disengaged from the movable groove 311, and the other end of the fan-shaped plate 315 is always inside the movable groove 311.
[0023] Among them, the servo motor 313 and the fan-shaped plate 315 can dynamically adjust the wind-receiving area of the blade 310 to prevent strong winds from damaging the generator 303 or the tipping bucket rain gauge 1. At the same time, the clutch 304 and the brake disc 305 can disconnect the power in extreme weather to protect the core components. Compared with traditional precipitation monitoring devices, this precipitation monitoring device with wind power generation function can effectively prevent the generator 303 from being damaged by excessive wind speed by dynamically adjusting the wind-receiving area of the blade 310 in conjunction with the clutch 304 and the brake disc 305.
[0024] like Figures 1 to 6As shown, the mounting mechanism 2 includes a mounting base 21 bolted to the front end of the tipping bucket rain gauge 1, a housing 301 bolted to the front end of the mounting base 21, a lightning protection rod 22 bolted to the top of the mounting base 21, and a ground wire 23 bolted to the bottom of the mounting base 21; the lightning protection rod 22 is electrically connected to the ground wire 23, and the bottom end of the ground wire 23 extends to the ground.
[0025] Among them, the lightning protection rod 22, together with the ground wire 23, effectively guides lightning and prevents the equipment from being damaged by lightning strikes; the metal casing 301 provides additional electromagnetic shielding to protect the internal circuitry. Compared with traditional precipitation monitoring devices, this precipitation monitoring device with wind power generation function can effectively protect the tipping bucket rain gauge 1 and the wind power generation mechanism 3 through the lightning protection rod 22 and the ground wire 23, preventing them from being damaged by lightning strikes and making it easy to use.
[0026] like Figure 1 As shown, in the initial state, the inner side of the sector plate 315 and the outer side of the blade 310 are on the same horizontal plane.
[0027] When the inner side of the fan-shaped plate 315 and the outer side of the blade 310 are on the same horizontal plane, the wind-receiving area of the blade 310 is the largest, which can quickly provide wind energy to the generator 303.
[0028] The tipping bucket rain gauge 1 has a 45-degree inward-sloping blade-shaped opening at the top; the diameter of the opening is specified as 20cm, and the height of the opening is mostly 0.7m-1.2m.
[0029] Working principle and usage process: Fix the tipping bucket rain gauge 1 in a flat, open area, adjust it to ensure measurement accuracy, ensure there are no obstructions around it, ground it through ground wire 23, and install the lightning protection rod 22 vertically above the mounting base 21 and connect it to the lightning protection system; install the housing 301 on the side of the mounting base 21, with the slot 302 facing the main wind direction, check whether the connection between the blade 310 and the hub 309 is firm, the natural wind drives the blade 310 to rotate and then accelerates it through the gearbox 306, thereby driving the generator 303 to generate electricity; the electrical energy is stored in the battery, when the wind speed is too high, the servo motor 313 pushes the fan-shaped plate 315 to cover the movable slot 311, reducing the wind-receiving area of the blade 310, if the wind speed still cannot be controlled, the clutch 304 disconnects the power transmission, and the brake disc 305 brakes the rotating shaft 307.
