Description

Technical Field

[0001] The utility model relates to the technical field of rainfall monitoring, in particular to a rainfall monitoring device for a tipping bucket type rainfall station system. Background Art

[0002] The tipping bucket rain gauge, also known as the tipping bucket rain gauge, is a precipitation measuring instrument that can observe rainfall in real time and convert rainfall into digital information output in the form of switch quantity to meet the needs of information transmission, processing, recording and display.

[0003] Existing rainfall detection devices are usually used outdoors, so it is easy to accumulate dust and impurities, especially in the autumn when there are many fallen leaves. If the fallen leaves fall on the water inlet and block the water inlet, in order to ensure the accuracy of rainfall monitoring, personnel are required to clean the impurities. Usually, a scraper is used to scrape the water inlet to prevent impurities from blocking the water inlet. However, the impurities still cannot be discharged from the water inlet, thus affecting the accuracy of rainfall monitoring device in measuring rainfall. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0005] A rainfall monitoring device for a tipping bucket rain gauge system comprises a rainfall monitoring box, the lower end of the inner cavity of the rainfall monitoring box is rotatably connected to one side of a tipping bucket metering assembly, a water-permeable plate is installed in the inner cavity of the rainfall monitoring box, and the water-permeable plate is rotatably connected to an impurity discharge mechanism:

[0006] The impurity discharge mechanism includes a fixed plate, a motor, a rotating shaft, a cleaning plate and an impurity collection box. The fixed plate is fixedly connected to the inner cavity of the rainfall monitoring box, the lower end of the motor is fixedly connected to the upper surface of the fixed plate, the outer wall of the rotating shaft is rotatably connected to the water-permeable plate, the lower end of the rotating shaft is fixedly connected to the output end of the motor, the cleaning plate is installed on the outer wall of the rotating shaft, and the outer wall of the impurity collection box is slidably connected to the inner wall of the water-permeable plate.

[0007] As an improvement of the above technical solution, the impurity discharge mechanism includes a spring, a lifting plate and a signal transmitter, the lower end of the spring is fixedly connected to the inner cavity of the impurity collection box, the lower surface of the lifting plate is fixedly connected to the upper end of the spring, and the outer wall of the lifting plate is slidably connected to the inner cavity of the impurity collection box, and the upper end of the signal transmitter is fixedly connected to the lower surface of the lifting plate.

[0008] As an improvement of the above technical solution, there are multiple cleaning plates evenly arranged on the outer wall of the rotating shaft, and the cleaning plates are arranged obliquely on the outer wall of the rotating shaft and overlap with the upper surface of the permeable plate.

[0009] As an improvement of the above technical solution, water outlets are provided in the inner cavity of the impurity collection box and on the surface of the lifting plate.

[0010] Beneficial effects of the utility model:

[0011] 1. Clean the impurities on the surface of the permeable plate by starting the impurity discharge mechanism to prevent impurities from clogging the permeable plate installed in the inner cavity of the rainfall monitoring box. Start the motor to drive the rotating shaft and the cleaning plate to rotate, and then clean the impurities on the surface of the permeable plate, so that the impurities enter the impurity collection box to prevent impurities from staying on the permeable plate, thereby improving the accuracy of the rainfall monitoring device in monitoring rainwater.

[0012] 2. When impurities enter the inner cavity of the impurity collection box, the impurities rely on gravity to move the lifting plate downward, thereby driving the signal transmitter to move downward. When there are too many impurities, the signal transmitter contacts the inner cavity of the impurity collection box, and then the signal transmitter is activated to notify the personnel, making it convenient for the personnel to clean the impurities in the inner cavity of the impurity collection box, thereby improving the accuracy of rainfall monitoring.

[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0020] See also Figure 1-5 The utility model provides a technical solution: a rainfall monitoring device for a tipping bucket rain gauge system, comprising a rainfall monitoring box 1, the lower end of the inner cavity of the rainfall monitoring box 1 is rotatably connected to one side of a tipping bucket metering component 2, a water-permeable plate 3 is installed in the inner cavity of the rainfall monitoring box 1, and the water-permeable plate 3 is rotatably connected to an impurity discharge mechanism 4:

[0021] The impurity discharge mechanism 4 includes a fixed plate 401, a motor 402, a rotating shaft 403, a cleaning plate 404 and an impurity collection box 405. The fixed plate 401 is fixedly connected to the inner cavity of the rainfall monitoring box 1, the lower end of the motor 402 is fixedly connected to the upper surface of the fixed plate 401, the outer wall of the rotating shaft 403 is rotatably connected to the water-permeable plate 3, the lower end of the rotating shaft 403 is fixedly connected to the output end of the motor 402, the cleaning plate 404 is installed on the outer wall of the rotating shaft 403, and the outer wall of the impurity collection box 405 is slidably connected to the inner wall of the water-permeable plate 3.

[0022] By starting the impurity discharge mechanism 4 to clean the impurities on the surface of the water-permeable plate 3, the impurities are prevented from clogging the water-permeable plate 3 installed in the inner cavity of the rainfall monitoring box 1. The motor 402 is started to rotate to drive the rotating shaft 403 and the cleaning plate 404 to rotate, thereby cleaning the impurities on the surface of the water-permeable plate 3, so that the impurities enter the impurity collection box 405, preventing the impurities from staying on the water-permeable plate 3, thereby improving the accuracy of the rainfall monitoring device for monitoring rainwater.

[0023] Specifically, the impurity discharge mechanism 4 includes a spring 406, a lifting plate 407 and a signal transmitter 408. The lower end of the spring 406 is fixedly connected to the inner cavity of the impurity collection box 405, the lower surface of the lifting plate 407 is fixedly connected to the upper end of the spring 406, and the outer wall of the lifting plate 407 is slidably connected to the inner cavity of the impurity collection box 405, and the upper end of the signal transmitter 408 is fixedly connected to the lower surface of the lifting plate 407.

[0024] Impurities enter the inner cavity of the impurity collection box 405, and the impurities rely on gravity to move the lifting plate 407 downward, thereby driving the signal transmitter 408 to move downward. When there are too many impurities, the signal transmitter 408 contacts the inner cavity of the impurity collection box 405, and then the signal transmitter 408 is activated to notify the personnel, making it convenient for the personnel to clean the impurity inner cavity of the impurity collection box 405, thereby improving the accuracy of rainfall monitoring.

[0025] Specifically, there are multiple cleaning plates 404 that are evenly arranged on the outer wall of the rotating shaft 403 , and the cleaning plates 404 are obliquely arranged on the outer wall of the rotating shaft 403 and overlap with the upper surface of the water-permeable plate 3 .

[0026] The rotating shaft 403 rotates to rotate the cleaning plate 404, and the cleaning plate 404 is inclined to remove impurities on the surface of the water-permeable plate 3, preventing impurities from adhering to the surface of the water-permeable plate 3 due to rainwater and being unable to be removed, thereby improving the efficiency of the cleaning plate 404 in cleaning the water-permeable plate 3.

[0027] Specifically, water outlets are provided in the inner cavity of the impurity collecting box 405 and on the surface of the lifting plate 407 .

[0028] The rainwater that enters the inner cavity of the impurity collection box 405 along with the impurities can be discharged through the water outlet, preventing the rainwater from accumulating in the inner cavity of the impurity collection box 405 and being unable to be discharged, thereby making the monitoring of rainwater more accurate and indirectly improving the accuracy of rainwater monitoring.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
