Description

Technical Field

[0001] The utility model relates to the technical field of hydrological detection, in particular to a rainfall detection device. Background Art

[0002] Hydrology is an important basic support for water conservancy work, and more hydrological detection and monitoring technologies are needed to gradually form a comprehensive hydrological monitoring station with complete projects and relatively reasonable layout, including water level, flow, rainfall, water quality, groundwater, evaporation, sediment, etc. Among them, rainfall detection is the basis of hydrological research and an important basis for hydrological monitoring and management. However, the relevant detection devices in rainfall detection are easily disturbed by the surrounding environment, such as wind, terrain or buildings, which ultimately leads to deviations in measurement results. Therefore, it is necessary to improve the stability of the equipment and the convenience of maintenance to ensure the long-term normal operation of the equipment and the continuity of data. Utility Model Content

[0003] In view of the defects in the prior art, the utility model provides a rainfall detection device.

[0004] A rainfall detection device comprises a mounting tube and a water bucket clamped on the top of the mounting tube, wherein a sensor and a signal recorder are arranged inside the mounting tube, a water outlet is arranged at the bottom of the mounting tube, a connecting structure is fixed to the side of the mounting tube, and the connecting structure comprises a fixed connecting part and an elastic locking part; wherein the fixed connecting part comprises a fixed base strip and a plurality of connecting base strips, the fixed base strip comprises a fixed section fixed to the outer wall of the mounting tube, the end of the fixed section is bent and extended outwardly to form a connecting section, a connecting base strip capable of changing the fixing angle is fixed on the connecting section, a plurality of fixing holes are opened on the connecting base strip, and a threaded connecting structure for fixing to a preset platform is arranged in the fixing hole; the elastic locking part comprises an elastic rope arranged inside the mounting tube, and both ends of the elastic rope pass through the mounting tube.

[0005] Preferably, an annular channel is provided in the installation tube, and the elastic rope is passed through the annular channel. An annular channel is designed inside the installation tube, and the elastic rope is passed through the annular channel. Such a design can make the elastic rope form a closed loop inside the installation tube, and by adjusting the tension of the elastic rope, additional stability can be provided for the installation tube.

[0006] Preferably, a guide tube connected to the annular channel is fixed to the outer wall of the installation tube, and the elastic rope passes through the guide tube. The guide tube is provided to guide the elastic rope to pass through the annular channel inside the installation tube to the outside. It ensures that the elastic rope can maintain a certain direction and position when passing through the installation tube, which is convenient for subsequent fixing and adjustment. At the same time, the guide tube can also play a certain protective role for the elastic rope, avoiding direct contact and friction between the elastic rope and the outer wall of the installation tube, thereby extending the service life of the elastic rope.

[0007] Preferably, a screw hole is provided on the connection section, and a threaded connection structure for fixing the connection base strip is passed through the screw hole. The screw hole provided on the connection section is for fixing the connection base strip in cooperation with the threaded connection structure. By rotating the threaded connection structure (such as a bolt or a screw), it can be tightly fixed on the connection section, thereby achieving a firm connection between the connection base strip and the fixed connection portion.

[0008] Preferably, a plurality of the connecting base strips can be connected and fixed to each other. The connecting base strips are designed to be connected and fixed to each other, so that the number of connecting base strips can be increased or decreased according to actual needs to adapt to installation platforms of different shapes and sizes. By using a plurality of connecting base strips in combination, the installation stability and adaptability of the rainfall detection device can be further improved.

[0009] Preferably, the sensor includes an upper bucket, a metering bucket and a spring switch. The sensor is one of the core components of the rainfall detection device and is used to sense and measure the amount of rainwater. The upper bucket is responsible for collecting rainwater and directing it into the metering bucket; the metering bucket measures the volume or weight of rainwater through a precise metering mechanism; the spring switch serves as a trigger mechanism of the sensor. When the amount of rainwater in the metering bucket reaches a certain amount, the spring switch will be triggered to generate a signal output.

[0010] Preferably, the signal recorder comprises a counter, a switch circuit and a control circuit board.

[0011] The beneficial effects of the utility model are embodied in:

[0012] In the entire rainfall detection device of the utility model, since the connecting base strip can change the fixing angle, the installer can adjust the angle of the connecting base strip according to the actual shape, height and angle of the platform to be installed, thereby ensuring that the installation tube can form the best fit with the platform surface, achieving a more stable installation effect, and at the same time, it can be installed in certain special locations (such as the top of a small building or an irregular platform). Therefore, even in the face of limited space or irregularly shaped installation environments, the equipment can be easily installed, greatly improving the installation range of the equipment; further, the fixed base strip and the connecting base strip of the fixed connection part can adapt to different installation environments through bending and angle adjustment, and are firmly fixed to the platform through a threaded connection structure, and the elastic rope design of the elastic locking part can be directly connected to the external installation platform. The platform forms a certain anti-loosening force on the installation tube, further increasing the stability of the equipment. This structural design can effectively resist the interference of external environment such as wind, terrain or buildings, and reduce the deviation of measurement results; further, the fixing holes and threaded connection structure of the connection structure ensure that the equipment can be quickly installed and disassembled, and the elastic rope can be disassembled and assembled more quickly, so it is convenient for daily maintenance and inspection; further, since the stability and maintenance convenience of the equipment have been improved, the rainfall detection device can maintain normal operation for a longer time, reducing the downtime caused by equipment failure or improper maintenance. At the same time, the setting of the sensor and the signal recorder enables the equipment to record rainfall data in real time and accurately, and send the data to the management center through a suitable signal transmission method to ensure the continuity and integrity of the data.
