Description

Technical Field

[0001] The utility model relates to the field of rainfall monitoring, and particularly to a rainfall collection device. Background Technique

[0002] Rainfall refers to the total amount of rainfall (snowfall) within 12 or 24 hours. It can also refer to the liquid or solid (after melting) water that falls from the sky to the ground and accumulates on a horizontal surface without evaporation, infiltration, or loss. The precipitation is measured in mm and is rounded to one decimal place in meteorological observations. It can intuitively represent the amount of rainfall. Rainfall is generally measured by a rain gauge, so the precipitation may include a small amount of dew, frost, and rime. In meteorology, there are often annual, monthly, daily, 12-hour, 6-hour, or even 1-hour precipitation amounts. The rain and snow that fall within 6 hours are all melted into water, which is called the 6-hour precipitation amount; the rain and snow that fall within 24 hours are all melted into water, which is called the 24-hour precipitation amount. The monitoring of rainfall is generally carried out by a rainfall collection device.

[0003] For example, the authorized announcement number, CN 214150043 U, discloses a new type of portable rainfall collection device, which relates to the field of meteorological monitoring.

By setting the box cover, magnet strip, handle, and screw rod, when in use, when collecting rainfall, open the box cover and rotate the screw rod to make the rain gauge move upward to collect rainfall. When the rainfall collection is completed, rotate the screw rod in the reverse direction to store the rain gauge, close the box cover, and the magnet strip will adsorb the box cover, then you can hold the handle and lift the box body to move, achieving the effect of being easy to carry.

[0004] However, in the above technology, the diameter of the rain gauge is significantly larger than that of the measuring cup, so that the rainwater collected in the rain gauge needs to be further calculated to obtain the rainfall value after being measured by the measuring cup, which is rather troublesome. Therefore, there is an urgent need in the market to develop a rainfall collection device to help people solve the existing problems. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: a rainfall collection device, including a protective box body 1, a display screen 101 is fixedly arranged on the front end face of the protective box body 1, a conical rainfall measuring cylinder 2 is fixedly arranged on one side of the upper end of the protective box body 1, the lower end of the conical rainfall measuring cylinder 2 extends into the protective box body 1 and is fixedly connected with a folding angle diversion pipe 201, a measuring cylinder 3 is fixedly arranged inside the protective box body 1, a circular opening 301 is arranged on one side of the middle of the upper end face of the measuring cylinder 3, a support pipe 302 is fixedly connected to the upper end of the circular opening 301, an infrared distance measuring instrument 303 is fixedly connected to the upper end of the support pipe 302, a guide rod 4 is fixedly connected to one side of the middle inside the measuring cylinder 3, the lower end of the guide rod 4 is connected with a sliding ring 402, one side of the sliding ring 402 and directly below the circular opening 301 is fixedly connected with a foam scale board 404, a closed pipe 5 is fixedly connected to the lower end of one side of the measuring cylinder 3, and a folding angle drain pipe 501 is fixedly connected to the lower end of the closed pipe 5.

[0024] Further, the lower end of the folding angle diversion pipe 201 passes through the upper end face of the measuring cylinder 3 and extends into the measuring cylinder 3. The inner diameter of the measuring cylinder 3 is the same as the inner diameter of the conical rainfall measuring cylinder 2. Rainwater is collected by the conical rainfall measuring cylinder 2, and the rainwater is diverted into the measuring cylinder 3 through the folding angle diversion pipe 201. The rainwater is diverted to the inner side wall of the measuring cylinder 3 through the folding angle part of the folding angle diversion pipe 201, so that the rainwater flows down along the inner wall of the measuring cylinder 3, which can reduce the disturbance caused by the falling rainwater to the water level inside the measuring cylinder 3. After the rainwater accumulates inside the measuring cylinder 3, the foam scale board 404 is lifted up.

[0025] Further, rectangular sliding grooves 401 are arranged on both end faces of the guide rod 4, and rectangular limiting parts 403 are fixedly connected to both sides inside the sliding ring 402.

[0026] Further, the two rectangular limiting parts 403 on the inner side of the sliding ring 402 respectively slide into the two rectangular sliding grooves 401 on the guide rod 4. When the foam scale board 404 floats and rises, the sliding ring 402 slides along the guide rod 4 to guide the foam scale board 404. At the same time, the rectangular limiting parts 403 slide along the rectangular sliding grooves 401 to limit the rotation of the sliding ring 402, ensuring that the foam scale board 404 is directly below the circular opening 301. The infrared distance measuring instrument 303 is connected with a data processing device. When there is no rainwater in the measuring cylinder 3, the distance detected by the infrared distance measuring instrument 303 between the foam scale boards 404 is set as a preset value. After the rainwater enters the measuring cylinder 3, the distance detected by the infrared distance measuring instrument 303 between the foam scale boards 404 is set as a detection value. By subtracting the detection value from the preset value through the data processing device, the height of the rainwater in the measuring cylinder 3 can be obtained. At this time, the height of the rainwater is the rainfall amount, and the rainfall amount value is displayed through the display screen 101.

[0027] Further, the lower end of the folding angle drain pipe 501 passes through one side of the protective box body 1 and extends to the outside, and the upper end of the folding angle drain pipe 501 is communicated with the middle inside the closed pipe 5.

[0028] Furthermore, a pull rod 6 is arranged in the middle of the closed pipe 5. One end of the pull rod 6 is fixedly connected with a circular sealing plate 601. One side of the circular sealing plate 601 is flush with the inner wall of the measuring cylinder 3. The circular sealing plate 601 is driven by the pull rod 6 to move along the closed pipe 5 to one side, so that the upper end of the angled drain pipe 501 is communicated with the measuring cylinder 3 through the closed pipe 5, and the rainwater inside the measuring cylinder 3 can be discharged from the angled drain pipe 501.

[0029] Furthermore, the other end of the pull rod 6 extends out of one end face of the protective box body 1 and is fixedly connected with a pulling plate 602, and the pull rod 6 is driven to move by pulling the pulling plate 602.

[0030] Working principle: During use, the inner diameter of the measuring cylinder 3 is the same as the inner diameter of the conical rain gauge 2. Rainwater is collected through the conical rain gauge 2, and the rainwater is guided to the inside of the measuring cylinder 3 through the angled diversion pipe 201. The rainwater is guided to the inner side wall of the measuring cylinder 3 through the angled part of the angled diversion pipe 201, so that the rainwater flows down along the inner wall of the measuring cylinder 3, which can reduce the disturbance caused by the falling rainwater to the water level inside the measuring cylinder 3. After the rainwater accumulates inside the measuring cylinder 3, the foam scale plate 404 is lifted. When the foam scale plate 404 floats and rises, it slides along the guide rod 4 through the slip ring 402 to guide the foam scale plate 404. At the same time, it slides along the rectangular chute 401 through the rectangular limiting part 403 to limit the rotation of the slip ring 402, ensuring that the foam scale plate 404 is directly below the circular opening 301. An infrared rangefinder 303 is connected with a data processing device. When there is no rainwater in the measuring cylinder 3, the distance detected by the infrared rangefinder 303 between the foam scale plates 404 is set as a preset value. After rainwater enters the measuring cylinder 3, the distance detected by the infrared rangefinder 303 from the foam scale plate 404 is set as a detected value. The height of the rainwater in the measuring cylinder 3 can be obtained by subtracting the detected value from the preset value through the data processing device. At this time, the height of the rainwater is the rainfall amount, and the rainfall amount value is displayed through the display screen 101. After the measurement is completed, the pull rod 6 is driven to move by pulling the pulling plate 602. The pull rod 6 drives the circular sealing plate 601 to move along the closed pipe 5 to one side, so that the upper end of the angled drain pipe 501 is communicated with the measuring cylinder 3 through the closed pipe 5, and the rainwater inside the measuring cylinder 3 can be discharged from the angled drain pipe 501.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
