[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] As attached Figure 1 To Attachment Figure 4 As shown: a rain gauge anti-clogging device includes a shell 1, the inner wall of the shell 1 is fixedly connected with a funnel 2, the funnel 2 is located at the top of the shell 1, and can guide rainwater falling from the top of the shell 1 to the inside of the shell 1, so that the rainwater can flow to the bottom of the shell 1, thereby realizing the monitoring of rainfall.

[0022] The dredging assembly 3 is installed inside the shell 1. The dredging assembly 3 includes two groups of support plates 301 fixedly connected to the inner wall of the shell 1. A lifting plate 302 is arranged between the two groups of support plates 301. The upper surface of the lifting plate 302 is provided with two sliding holes 303. The inner wall of each sliding hole 303 is slidably connected with a sliding rod 304. The top end of each sliding rod 304 and the bottom end of each sliding rod 304 are respectively connected to a side surface of each group of support plates 301 close to each other. The outer surface of each sliding rod 304 is sleeved with a spring 305. The spring 305 is located below the lifting plate 302, and the bottom end of each spring 305 is connected to the upper surface of the support plate 301 below. The upper surface of the lifting plate 302 is fixed A support rod 306 is fixedly connected, and a scraper 307 is fixedly connected to the top of the support rod 306. The scraper 307 is adapted to the internal size of the water outlet at the bottom of the funnel 2. An L-shaped plate 308 is fixedly connected to the upper surface of one of the support plates 301 in each group of support plates 301. An electric push rod 309 is installed on the bottom surface of the top of each L-shaped plate 308. The bottom end of the electric push rod 309 is located directly above the lifting plate 302. When the electric push rod 309 is extended or retracted, it will push the lifting plate 302 to descend, and the lifting plate 302 will lower the support rod 306 and the scraper 307. When the scraper 307 passes through the funnel 2, it will scrape off the debris, thereby completing the dredging of the funnel 2 and allowing water to flow to the bottom of the shell 1.

[0023] In order to prevent collision damage between the lifting plate 302 and the funnel 2, the upper surface of another support plate 301 in each group of support plates 301 is slidably connected to the limit rod 310, and the bottom end of each limit rod 310 is fixedly connected to the limit plate 311, and the top of each limit rod 310 is connected to the bottom surface of the lifting plate 302. When the spring 305 pushes the lifting plate 302 upward, the lifting plate 302 will pull the limit rod 310 to slide upward, and the limit rod 310 will also drive the limit plate 311 to rise. The limit plate 311 will first contact the bottom of the support plate 301, so as to limit the rising height of the lifting plate 302 and avoid collision between the lifting plate 302 and the funnel 2.

[0024] In order to facilitate the staff to view the monitoring value of rainfall, a display 4 is installed on the outer surface of the shell 1, and a liquid level meter 5 is installed on the inner bottom wall of the shell 1. The liquid level meter 5 can be used to monitor the rainfall collected inside the shell 1. The liquid level meter 5 will feed back the monitored value to the display 4, and the staff can directly view the rainfall monitoring data from the display 4. In order to ensure the stability of the shell 1 for rainwater collection and monitoring, the outer surface of the shell 1 is fixedly connected with a ring-arranged support 6, and the side of the two groups of supports 6 close to each other is fixedly connected with a reinforcement ring 7. The support 6 is used to facilitate the staff to fix the shell 1, and the support 6 will support the shell 1. At the same time, the reinforcement ring 7 will connect the supports 6, which can enhance the stability of the support 6 for the shell 1 and ensure the stability of rainwater collection. In order to prevent large debris from entering and falling into the funnel 2 and causing blockage, an annular frame 8 is clamped on the outer surface of the top end of the shell 1, and a blocking net 9 is fixedly connected to the inner wall of the annular frame 8. By clamping the annular frame 8 and the shell 1, the blocking net 9 can be fixed on the top of the shell 1 to block large impurities.

[0025] Working principle: When the bottom of the funnel 2 needs to be dredged, the electric push rod 309 is started to extend and retract, and the electric push rod 309 will push the lifting plate 302, and the lifting plate 302 will drive the support rod 306 and the scraper 307 to slide down. At the same time, the lifting plate 302 will compress the spring 305, and the scraper 307 will pass through the funnel 2. During the descent of the scraper 307, the debris inside the funnel 2 will be scraped until the scraper 307 reaches the bottom of the funnel 2. The dredging of the funnel 2 is completed, and the water can flow normally from the funnel 2, ensuring the accuracy of the measurement.

[0026] After the dredging is completed, the electric push rod 309 is started to reset, the spring 305 will gradually expand, the spring 305 will push the lifting plate 302 upward, the support rod 306 and the scraper 307 will gradually pass through the funnel 2 to reach the top of the funnel 2, so as to facilitate the dredging of the funnel 2 next time.
