Description

Technical Field

[0001] This utility model relates to the technical field of rainfall measurement devices, specifically a rainfall measurement device used in hydropower plants. Background Technology

[0002] A tipping bucket rain gauge, also known as a tipping bucket rain sensor, is an instrument used by meteorological stations, hydrological stations, agriculture, forestry, national defense and other relevant departments to measure liquid precipitation, precipitation intensity and precipitation start and end time. Rainfall is an important disaster data. In the process of power generation by dams and power plants, the measurement of rainfall is extremely important. Traditional rainfall measurement usually requires the construction of a large number of rainfall monitoring stations, and each rainfall monitoring station needs to be equipped with multiple tipping bucket rain gauges to monitor rainfall.

[0003] However, existing tipping bucket rain gauges suffer from leaf drop during use, which clogs the funnel and prevents rainwater from flowing into it in time. This results in significantly delayed or low readings during short periods of heavy rainfall, affecting measurement accuracy. Therefore, these measures do not meet current requirements. To address this, we propose a rain measurement device for use in hydroelectric power plants. Utility Model Content

[0004] The purpose of this invention is to provide a rainfall measurement device for use in hydropower plants, in order to solve the problem mentioned in the background art that when a tipping bucket rain gauge is in use, fallen leaves fall into the rain gauge funnel, which causes the funnel to be blocked by leaves, preventing rainwater from flowing into the tipping bucket in time. This results in a serious lag or low measurement value of the tipping bucket rain gauge during short-term heavy rainfall, affecting the accuracy of the measurement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rainfall measuring device used in a hydroelectric power plant, comprising a tipping bucket rain gauge body:

An anti-clogging filter cylinder is installed inside the secondary filter screen. The anti-clogging filter cylinder is welded to the secondary filter screen.

[0007] A rotating cylinder is rotatably installed at the upper end of the anti-clogging mesh cylinder. A wind-powered rotating bracket is installed at the upper end of the rotating cylinder and welded to the rotating cylinder. A connecting shaft is installed on one side of the rotating cylinder, and a material-pushing plate is installed at one end of the connecting shaft. The material-pushing plate is fixedly connected to the connecting shaft, and the lower end of the material-pushing plate is attached to the upper end of the top support filter screen.

[0008] Preferably, a leaf collection basket is installed on the outside of the tipping bucket rain gauge body, and the leaf collection basket is welded to the tipping bucket rain gauge body.

[0009] Preferably, a rainwater guiding funnel is installed below the secondary filter screen, and the rainwater guiding funnel and the tipping rain gauge body are integrally formed.

[0010] Preferably, the tipping bucket rain gauge body has three supporting legs arranged in a circular array on its lower end face, and the three supporting legs are welded to the tipping bucket rain gauge body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model can filter fallen leaves and debris by installing a top-supported filter screen, preventing fallen leaves from clogging the rainwater diversion funnel, allowing rainwater to flow into the tipping bucket in a timely manner through the rainwater diversion funnel, avoiding serious lag or low measurement values ​​of the device during short-term heavy rainfall, which would affect the accuracy of the measurement. The installation of a wind-powered rotating bracket can use wind power to drive the tilted material-pushing plate to rotate, so that the material-pushing plate pushes the fallen leaves into the fallen leaf collection basket, realizing automatic cleaning, preventing fallen leaves from accumulating at the top of the top-supported filter screen, and ensuring smooth rainwater flow.

[0015] 2. This utility model can collect fallen leaves by installing a leaf collection basket, which makes it easier for staff to centrally process the fallen leaves and makes the device more user-friendly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4 One embodiment of this utility model is a rainfall measurement device used in a hydroelectric power plant, comprising a tipping bucket rain gauge body 1.

[0023] The secondary filter 10 is installed inside the tipping bucket rain gauge body 1. Installing the secondary filter 10 allows for secondary filtration of rainwater, removing impurities and enhancing the practicality of the device. The tipping bucket rain gauge body 1 and the secondary filter 10 are connected by snap-fit. A top support filter 4 is placed on the upper end of the secondary filter 10. Installing the top support filter 4 allows for the filtration of fallen leaves and debris, preventing them from clogging the rainwater guide funnel 11. This ensures that rainwater can flow into the tipping bucket in a timely manner through the rainwater guide funnel 11, avoiding serious lag or low measurement values ​​during short-term heavy rainfall, which would affect the accuracy of the measurement. An anti-clogging mesh cylinder 5 is installed inside the secondary filter 10 and is welded to the secondary filter 10.

[0024] The rotating cylinder 6 is mounted on the upper end of the anti-clogging mesh cylinder 5. A wind-powered rotating bracket 7 is installed on the upper end of the rotating cylinder 6. The wind-powered rotating bracket 7 can drive the inclined material-dispensing plate 9 to rotate with the help of wind, so that the material-dispensing plate 9 dispenses the fallen leaves into the fallen leaf collection basket 2, realizing automatic cleaning and preventing the fallen leaves from accumulating on the top of the filter screen 4, ensuring smooth flow of rainwater. The wind-powered rotating bracket 7 is welded to the rotating cylinder 6. A connecting shaft 8 is installed on one side of the rotating cylinder 6. A material-dispensing plate 9 is installed on one end of the connecting shaft 8. The material-dispensing plate 9 is fixedly connected to the connecting shaft 8. The lower end of the material-dispensing plate 9 is in contact with the upper end of the top of the filter screen 4.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4The tipping rain gauge body 1 is equipped with a leaf collection basket 2 on its exterior. The leaf collection basket 2 can collect fallen leaves, making it convenient for staff to centrally process the fallen leaves and making the device more user-friendly. The leaf collection basket 2 is welded to the tipping rain gauge body 1. A rainwater guide funnel 11 is installed below the secondary filter screen 10. The rainwater guide funnel 11 and the tipping rain gauge body 1 are integrally formed. The lower end face of the tipping rain gauge body 1 has three support legs 3 in a circular array. The three support legs 3 are welded to the tipping rain gauge body 1. The upper edge of the top support filter screen 4 is provided with a platform. The anti-clogging net cylinder 5 is connected to the top support filter screen 4 through a slot. The connecting shaft 8 is welded to the rotating cylinder 6. The upper end of the wind-powered rotating bracket 7 is provided with seven blades. The tipping rain gauge body 1 is model BOY-YL05-1.

[0026] Working Principle: When it rains, rainwater falls into the device. The top support filter 4 and the secondary filter 10 filter the rainwater. Then, the rainwater enters the lower tipping bucket inside the device through the rainwater guide funnel 11. When fallen leaves fall on the top support filter 4, the wind blowing on the wind-powered rotating bracket 7 causes the rotating cylinder 6 to drive the connecting shaft 8 and the material-pushing plate 9 to rotate. This causes the tilted material-pushing plate 9 to push the fallen leaves into the fallen leaf collection basket 2, ensuring smooth flow of rainwater. The installation of the secondary filter 10 allows for secondary filtration of rainwater, removing impurities and enhancing the device's practicality. The installation of the top support filter 4 allows for further filtration of the rainwater. The system filters fallen leaves and debris to prevent them from clogging the rainwater guide funnel 11, allowing rainwater to flow into the tipping bucket in a timely manner. This avoids significant lag or underestimation of the device's measurement values ​​during short-term heavy rainfall, which would affect measurement accuracy. The wind-powered rotating bracket 7 uses wind power to rotate the tilted material-pushing plate 9, which pushes the fallen leaves into the fallen leaf collection basket 2 for automatic cleaning. This prevents fallen leaves from accumulating on top of the filter screen 4, ensuring smooth rainwater flow. The fallen leaf collection basket 2 collects the fallen leaves, facilitating centralized processing by staff and making the device more user-friendly.
