[0002] Waterlogging prevention early warning devices have wide application in the fields of meteorology, water conservancy and geological disaster warning. In the prior art, devices with high measurement accuracy usually adopt complex sensor structures or large-capacity water collecting components, resulting in large overall volume, difficulty in flexible deployment in narrow spaces (such as urban drainage wellheads and mountain monitoring points), and significant increase in transportation and installation costs. Although small-sized devices are convenient to carry and lay out, they have limited water collecting area or small water level variation range, resulting in insufficient water level resolution for the same volume of precipitation, difficulty in accurately capturing small rainfall, and data distortion in low-intensity rainfall scenarios, which cannot meet the high-precision monitoring requirements.

[0027] Reference Figures 1 to 5 A waterlogging prevention early warning device, comprising a rain bucket 100 and a cylinder 200 with a rain detector 211 inside, the rain bucket 100 is an inverted umbrella-shaped structure, comprising a through pipe 170, an umbrella surface 160, a framework and a fixed seat 180. The through pipe 170 is assembled on the fixed seat 180, and the fixed seat 180 is assembled in the cylinder 200; the framework is assembled on the through pipe 170 and can be folded and unfolded, and the umbrella surface 160 is radially covered outside the framework, and the umbrella surface 160 is provided with a water through hole 161. The rain bucket 100 has two states of folding and unfolding, and when folded, the rain bucket 100 can be placed in the cylinder 200, in order to facilitate the complete storage of the rain bucket 100, the through pipe 170 is a telescopic pipe structure. When unfolded, the umbrella surface 160 forms a rain receiving cavity for receiving rainwater, and the rainwater in the rain receiving cavity falls into the cylinder 200 through the water through hole 161.

[0028] Compared with the prior art, the rain bucket 100 of the present application is designed as an inverted umbrella-shaped structure that can be folded and unfolded, and can be completely stored in the cylinder 200 when folded, which significantly reduces the overall volume of the device and effectively solves the problem of large space occupation of traditional equipment transportation and installation. At the same time, the cylinder 200 adopts a small-diameter, long-cylinder 200 structure that is matched with the rain bucket 100, which significantly increases the water level under the same precipitation volume, and cooperates with the large-area water collection area formed after the rain bucket 100 is unfolded to efficiently collect rainwater. The water level change amplitude of the same volume of precipitation is greatly amplified by the synergistic effect of the two, thereby ensuring the rainfall detection accuracy and providing a high-reliability data basis for waterlogging prevention early warning.

[0029] In the application, the frame includes main ribs 110, branch ribs 120, support rings 130, sliding rings 140 and stop pieces 150. The support rings 130 and the sliding rings 140 are coaxial. The main ribs 110 and the branch ribs 120 are matched to form a frame body. The umbrella surface 160 covers the main ribs 110. The support rings 130 are fixed on the through pipe 170. The sliding rings 140 are axially slidably assembled on the through pipe 170. One end of the main ribs 110 is hinged to the sliding rings 140, and the other end is free. One end of the branch ribs 120 is hinged to the middle of the main ribs 110, and the other end is hinged to the support rings 130. The stop pieces 150 are assembled on the through pipe 170 to limit the movement of the sliding rings 140 when the frame is unfolded. The user can manually unfold the umbrella surface 160 to collect rainwater,

[0030] The stop pieces 150 include control rods 151. The middle of the control rods 151 is assembled on the through pipe 170 through torsion spring shafts 152. One end of the control rods 151 is a stop end 153, and the other end is a control end 154. The control end 154 extends from the surface of the through pipe 170 to facilitate control. The stop end 153 extends from the surface of the through pipe 170 to block the sliding rings 140. By pressing the control end 154, the stop end 153 is retracted into the through pipe 170 to release the locking of the sliding rings 140. When unfolded, the sliding rings 140 are blocked by the stop end 153 to maintain the unfolded state. When it needs to be folded, the locking can be released by pressing. The mechanical structure can conveniently fold and unfold the rainwater collecting bucket 100, improving the usability and maintenance efficiency of the device.

[0031] To further improve the detection accuracy, the sliding rings 140 extend downward to the umbrella surface 160 and are provided with water collecting hoppers 141. The water through holes 161 are located directly above the water collecting hoppers 141. The water collecting hoppers 141 are provided with through holes 142 facing the through pipe 170. The pipe wall of the through pipe 170 is provided with water inlets 171 corresponding to the through holes 142. The bottom of the through pipe 170 is provided with a water outlet 172. This design ensures that all collected rainwater is introduced into the cylinder 200, improving the rain detection accuracy. At the same time, the funnel structure of the water collecting hopper 141 can ensure that the rainwater is introduced into the cylinder 200 through the through pipe 170, reducing the problem of rainwater splashing and affecting detection. The bottom of the through pipe 170 is provided with a slope pipe 173 contacting the inner wall of the cylinder 200 to guide the rainwater to flow along the inner wall of the cylinder 200. This design avoids the direct impact of rainwater on the bottom of the cylinder 200, prevents water surface fluctuation from interfering with the reading of the rain gauge 211, and avoids measurement errors caused by water splashing, ensuring the stability and accuracy of water level monitoring.

[0032] For the convenience of the device maintenance, the bottom of the barrel 200 is equipped with a base 220, the upper surface of the base 220 cooperates with the inner wall of the barrel 200 to form a measuring cavity for containing rainwater; the base 220 and the barrel 200 are clamped and assembled, and a sealing ring 222 is assembled between the side surface of the base 220 and the inner wall of the barrel 200. The clamping structure facilitates the quick disassembly and maintenance of the barrel 200, and the sealing ring 222 prevents rainwater from leaking from the joint and ensures that the water level in the measuring cavity truly reflects the rainfall. The upper surface of the base 220 is funnel-shaped with a high middle and a low periphery, a drain pipe 223 is arranged in the middle of the funnel, and a drain valve 224 is arranged on the drain pipe 223. The funnel design is conducive to rainwater collection and avoids rainwater accumulation in the barrel 200 during drainage, which affects the next measurement. The drain valve 224 can automatically drain the rainwater in the barrel 200 after measurement is completed, without the need for manual drainage by staff. The barrel 200 is provided with an assembly seat 210 at the barrel opening, the middle of the assembly seat 210 is through for the passage of the pipe 170; the rain amount detector 211 is an ultrasonic detector, which is arranged at the bottom of the assembly seat 210 to detect the water level of the rainwater in the barrel 200, and the base 220 is provided with a reflection platform 221 corresponding to the rain amount detector 211. Compared with the immersion sensor, the ultrasonic detection is not affected by water quality and has better long-term stability.

[0033] In the present application, the barrel 200 is provided with a control module 230, and the rain amount detector 211 and the drain valve 224 are electrically connected with the control module 230. The control module 230 can realize intelligent management: when the detector detects that the water level exceeds the threshold value, the drain valve 224 is automatically opened to relieve pressure and avoid equipment damage; the valve is closed after the water level returns to normal, and the measurement function is restored.

[0034] The protection scope of the present application includes but is not limited to the above embodiments, and the protection scope of the present application is subject to the claims, any replacement, deformation, improvement of the present technology easily thought by those skilled in the art falls within the protection scope of the present application.
