Description

Technical Field

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

[0002] Precipitation monitoring is a crucial component of hydrological environmental monitoring. This involves collecting the amount of rain per unit time to estimate the current rainfall intensity, also known as rainfall intensity. Currently, rainfall monitoring typically uses tipping bucket rain gauges, which collect rainwater and then monitor the amount of rain per unit time to estimate rainfall.

[0003] For example, patent application number 202320359908.6 provides an automatic rainfall monitoring device, comprising a base with support feet at the bottom, a housing mounted on the base, a water collecting hopper mounted on the top of the housing, a conical foreign matter filter hopper with a small top and a large bottom, a support base parallel to the base, a metering bucket mounted in the center of the support base via a bracket, water holes formed on the support base corresponding to the tipping positions of the metering bucket, a water collecting chamber mounted on the base corresponding to the water holes, the top of the water collecting chamber connected to the bottom of the water hole via a hose, a liquid level gauge mounted in the water collecting chamber, a drain pipe formed in the center of the bottom of the water collecting chamber, and a drain solenoid valve mounted on the drain pipe. The device improves the accuracy of rainfall monitoring by preventing foreign matter from entering the housing and collecting rainfall at different time units within the same housing. However, during the turning process of the metering bucket, rainwater dripping from the water collecting bucket may enter both sides of the metering bucket at the same time, affecting the amount of rainwater collected by the metering bucket in a single action. In view of this, the present application provides an automatic rainfall monitoring device. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a rainfall monitoring device.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A rainfall monitoring device includes a box body. A water collecting hopper is provided at the top of the box body. A water pipe is provided at the bottom of the water collecting hopper. A measuring tipping bucket is provided below the water pipe. The middle position at the bottom of the measuring tipping bucket is rotatably installed on the box body. Water collecting cylinders are provided at both ends of the box body corresponding to the measuring tipping bucket. A first partition and two second partitions are provided in the inner cavity of the measuring tipping bucket. The first partition is vertically installed in the middle of the measuring tipping bucket and is perpendicular to the length direction of the measuring tipping bucket. The second partition includes a horizontal section and a vertical section. The two horizontal sections are arranged in parallel, and the opposite ends of the two horizontal sections are respectively vertically connected to the front and rear ends of the first partition. The opposite ends of the two vertical sections are respectively connected to the inner wall surfaces of the front and rear sides of the measuring tipping bucket.

[0007] Further, both ends of the measuring tipping bucket are set to be arc-shaped. Both ends of the measuring tipping bucket are open. Two arc-shaped baffles for respectively fitting both ends of the measuring tipping bucket are provided in the box body. The bottom height of the arc-shaped baffle is greater than the top entrance height of the water collecting cylinder.

[0008] Further, a top plate for blocking the top of the second partition is installed at the top of the measuring tipping bucket. A strip-shaped water inlet extending horizontally is provided in the middle of the top plate. The first partition is horizontally located in the middle of the water inlet.

[0009] Further, a pipe mouth sealing plate fixedly installed on the measuring tipping bucket is provided directly above the first partition. The upper surface of the pipe mouth sealing plate and the bottom end of the water pipe are set to be a matching arc-shaped structure. When the measuring tipping bucket is in a horizontal state, the pipe mouth sealing plate blocks the bottom end of the water pipe. The thickness of the first partition is less than the inner diameter of the water pipe.

[0010] Further, an inverted "C"-shaped bracket is fixedly installed at the bottom of the pipe mouth sealing plate. Both ends of the bracket are respectively fixedly connected to the middle parts of the front and rear side surfaces of the measuring tipping bucket.

[0011] Further, a shroud is provided at the top of the water collecting cylinder. When the measuring tipping bucket is in an inclined state, the downwardly inclined end thereof enters the shroud on the corresponding side.

[0012] The utility model has the following beneficial effects:

[0013] 1. By providing the first partition and the second partition in the measuring tipping bucket, when pouring water at one end of the measuring tipping bucket, the water dripping from the water pipe will first converge on the downwardly inclined side of the measuring tipping bucket, enabling the measuring tipping bucket to stay in the pouring state for a longer time, improving the rainwater drainage effect of the measuring tipping bucket, thereby ensuring the measurement accuracy and improving the rainfall monitoring accuracy.

[0014] 2. By setting a pipe mouth sealing plate on the metering bucket, the rainwater dripping from the sewer pipe will not drip into the two cavities in the metering bucket at the same time during the turning of the metering bucket, thereby ensuring that the rainwater dripping from the sewer pipe will only enter the cavity on one side of the metering bucket at the same time, further improving the metering accuracy and the rainfall monitoring accuracy.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 3 As shown, a typical embodiment of the present invention provides a rainfall monitoring device, comprising a housing 1, a water collecting bucket 2 disposed at the top of the housing 1, a downpipe 3 disposed at the bottom of the water collecting bucket 2, and a metering bucket 4 disposed below the downpipe 3. The metering bucket 4 is rotatably mounted on the housing 1 at the middle of its bottom. Specifically, an articulated seat is disposed within the housing 1, and the metering bucket 4 is rotatably mounted on the articulated seat. Water collecting cylinders 5 are disposed within the housing 1 at both ends of the metering bucket 4. When one end of the metering bucket 4 tilts downward, the rainwater collected within the metering bucket 4 enters the water collecting cylinder 5 on the corresponding side.

[0021] The inner cavity of the metering bucket 4 is provided with a first partition and two second partitions 7. The first partition 6 is vertically installed in the middle of the metering bucket 4, and the first partition 6 is perpendicular to the length direction of the metering bucket 4. Specifically, the length of the first partition 6 is less than the width of the inner cavity of the metering bucket 4.

[0022] The second partition 7 includes a transverse section 7.1 and a longitudinal section 7.2. The two transverse sections 7.1 are arranged in parallel, and the opposite ends of the two transverse sections 7.1 are respectively vertically connected to the front and rear ends of the first partition 6, and the opposite ends of the longitudinal sections are respectively connected to the front and rear inner wall surfaces of the metering bucket 4.

[0023] Specifically, by arranging the first partition 6 and the second partition 7, the first partition 6 and the second partition 7 divide the inner cavity of the metering bucket 4 into two "Z"-shaped cavities distributed front to back. When one end of the metering bucket 4 in the horizontal direction tilts downward, the rainwater dripping from the bottom end of the sewer pipe 3 will all enter the other cavity and move to the side of the metering bucket 4 tilted downward. In this way, the time for the metering bucket 4 to pour water is increased, and the two cavities of the metering bucket 4 are ensured to pour water more thoroughly into the water collecting cylinder 5 on the corresponding side, so as to improve the metering accuracy.

[0024] On this basis, the two ends of the metering bucket 4 are set to be arc-shaped, and the two ends of the metering bucket 4 are open, and two arc-shaped baffles 8 are provided in the box body 1 for fitting the two ends of the metering bucket 4 respectively, and the bottom height of the arc-shaped baffle 8 is greater than the top entrance height of the water collecting cylinder 5.

[0025] When the cavity on the front side of the metering bucket 4 pours water, the cavity on the rear side is in a state of collecting rainwater. At this time, the opening of the right cavity is blocked by one of the baffles until enough rainwater is accumulated in the cavity on the rear side, so that the metering bucket 4 corresponding to the end where the right cavity opening is located flips downward. At this time, the metering bucket 4 switches to a state where the right cavity pours water and the left cavity collects rainwater.

[0026] Among them, a top plate 9 is installed on the top of the metering bucket 4 to block the top of the second partition 7. A strip-shaped water inlet 10 extending laterally is opened in the middle of the top plate 9, and the first partition 6 is located in the middle of the water inlet 10 in the transverse direction.

[0027] Specifically, when water is poured from the left cavity on the front side of the metering bucket 4, the rainwater dripping into the right cavity will enter the part of the right cavity on the same side as the left cavity due to the tilt of the metering bucket 4. When this part of the right cavity is filled with rainwater, the rainwater will be concentrated on the right side of the right cavity, causing the weight of the right side of the metering bucket 4 to begin to increase. When the gravity on the right side of the metering bucket 4 increases more than the weight on the left side, the right side of the metering bucket 4 will flip downward and start the process of pouring water from the right cavity.

[0028] A pipe mouth sealing plate 11 fixedly mounted on the metering bucket 4 is provided directly above the first partition 6. The upper surface of the pipe mouth sealing plate 11 is arranged to form an arc structure that matches the bottom end of the sewer pipe 3. When the metering bucket 4 is in a horizontal state, the pipe mouth sealing plate 11 blocks the bottom end of the sewer pipe 3. The thickness of the first partition 6 is smaller than the inner diameter of the sewer pipe 3.

[0029] In this embodiment, when the metering tipping bucket 4 starts to tip downwards from the left end to the right end, the pipe mouth sealing plate 11 passes from left to right through the bottom end of the downpipe 3, and can prevent the rainwater dripping from the downpipe 3 from falling into the left cavity by continuously blocking the bottom pipe mouth of the downpipe 3 from left to right before the right cavity crosses the bottom pipe mouth of the downpipe 3. After the pipe mouth sealing plate 11 crosses the bottom pipe mouth of the downpipe 3 to the right, all the rainwater dripping from the downpipe 3 will enter the left cavity.

[0030] With such a setting, the two cavities of the metering tipping bucket 4 can separately collect the rainwater dripping from the downpipe 3, especially preventing the situation where the rainwater dripping from the bottom pipe mouth of the downpipe 3 enters both cavities simultaneously during the tipping process of the metering tipping bucket 4, thereby improving the metering accuracy.

[0031] A bracket 12 in an inverted "C" shape is fixedly installed at the bottom of the pipe mouth sealing plate 11, and both ends of the bracket 12 are fixedly connected to the middle parts of the front and rear side surfaces of the metering tipping bucket 4 respectively. The bracket 12 mounts the pipe mouth sealing plate 11 on the metering tipping bucket 4.

[0032] A shroud 13 is provided at the top of the water collecting cylinder 5, and when the metering tipping bucket 4 is in an inclined state, its downwardly inclined end enters the corresponding shroud 13. By providing the shroud 13, when pouring water from any cavity of the metering tipping bucket 4, it can prevent rainwater from splashing, so that the rainwater collected in the metering tipping bucket 4 can be effectively poured into the water collecting cylinder 5, further ensuring the metering accuracy.

[0033] Specifically, a liquid level sensor can be provided in the water collecting cylinder 5 to detect the amount of rainwater collected in the water collecting cylinder 5, and a water outlet pipe can be provided at the bottom end of the water collecting cylinder 5 to drain the rainwater in the water collecting cylinder 5. This is the prior art and will not be elaborated here.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
