Description

Technical Field

[0001] This utility model relates to the field of rain gauge technology, specifically a rain gauge for meteorological detection. Background Technology

[0002] In meteorological monitoring, rainfall needs to be recorded, and rain gauges are used to measure the rainfall. A tipping bucket rain gauge sensor is a hydrological and meteorological instrument used to measure natural rainfall and convert it into digital information output in the form of a switching signal to meet the needs of information transmission, processing, recording, and display.

[0003] Currently, the tipping bucket rain gauges used collect rainwater through a top structure. After being filtered by a filter, the rainwater is collected by the internal tipping bucket. When a certain amount of water is collected in a single bucket, a mechanical tipping is triggered. A reed switch converts the physical displacement into an electrical pulse signal, and the rainfall is calculated by the number of tipping cycles. However, in current use, the filter is installed parallel to the top of the rain gauge. Because of this parallel installation, when the filter becomes clogged or blocked by foreign objects, the amount of rainwater entering the device changes, leading to detection errors. Therefore, an improved rain gauge for meteorological detection is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a rain gauge for meteorological detection to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rain gauge for meteorological detection, comprising an outer shell, a rain-collecting port fixedly installed at the top of the outer shell, a mounting foot fixedly installed at the bottom of the outer shell, a controller fixedly installed on the inner wall of the bottom of the outer shell, a filtering mechanism provided inside the outer shell near the top, and a metering mechanism provided inside the outer shell.

[0006] The filtration mechanism includes a pre-filter assembly and a post-filter assembly. The pre-filter assembly is disposed inside the outer casing, and the post-filter assembly is disposed at the bottom of the pre-filter assembly.

[0007] The pre-filter assembly includes a mounting ring, which is fixedly installed inside the outer casing. A threaded post is fixedly installed on the top of the mounting ring, and a filter cone mesh is provided on the top of the mounting ring. A threaded cap is installed on the external thread of the threaded post to facilitate preliminary filtration of dirt and prevent it from entering the device. At the same time, the filter cone mesh with a cone structure allows dirt to slide off to the outside, while ensuring that rainwater can continuously enter the device.

[0008] Preferably, there are six threaded posts and six threaded caps, arranged in a circular array around the center of the mounting ring, which facilitates the fixed installation of the filter cone.

[0009] Preferably, mounting holes are provided at the corresponding positions of the filter cone and the threaded post, and the threaded post passes through the mounting holes to facilitate the positioning and installation of the filter cone and the threaded post.

[0010] Preferably, the post-filtration assembly includes a collection hopper, which is fixedly installed at the bottom of the mounting ring. A water outlet pipe is fixedly installed at the bottom of the collection hopper, and a fixing ring is fixedly installed inside the water outlet pipe. A filter cylinder is installed inside the fixing ring, which facilitates secondary filtration of rainwater.

[0011] Preferably, the metering mechanism includes a mounting frame, which is fixedly installed inside the outer casing. A tilting bucket is rotatably mounted on the inner side of the mounting frame. A lever is fixedly mounted on the front and back of the tilting bucket. Limiting grooves are provided on both the front and back of the mounting frame. Contact switches are provided on the side walls of the limiting grooves. Fixing plates are fixedly mounted on the left and right sides of the outer casing. A drain pipe is fixedly mounted inside the fixing plate. A drain bucket is fixedly mounted on the top of the drain pipe.

[0012] Preferably, the lever is slidably installed inside the limiting groove, and the two sides of the tilting bucket are symmetrically provided with groove-shaped structures to facilitate the limiting sliding of the lever.

[0013] Preferably, through holes are provided on the left and right sides of the outer shell at positions corresponding to the drain pipe, and the drain pipe passes through the through holes to facilitate the discharge of rainwater from the outer shell through the drain pipe.

[0014] Compared with the prior art, this utility model provides a rain gauge for meteorological detection, which has the following beneficial effects:

[0015] 1. This rain gauge for meteorological monitoring uses a filter mechanism. During use, the filter cone structure filters out large debris. The cone-shaped filter structure prevents debris from accumulating on the surface of the filter cone, thus avoiding blockage. Secondly, the filter cylinder further filters rainwater, thereby preventing blockage of the internal pipes.

[0016] 2. This rain gauge for meteorological detection, through its metering mechanism, uses a tilting bucket to flip left and right during use. This causes a lever to press the contact switch left and right, generating an electrical signal, thereby calculating the number of times the tilting bucket flips, and thus realizing the calculation of rainfall.

[0029] Furthermore, six threaded posts 512 and six threaded caps 514 are provided, arranged in a circular array around the center of the mounting ring 511, which facilitates the fixed installation of the filter cone 513.

[0030] Furthermore, mounting holes are provided at corresponding positions of the filter cone 513 and the threaded post 512, and the threaded post 512 passes through the mounting holes, which facilitates the positioning and installation of the filter cone 513 and the threaded post 512.

[0032] To perform rainfall measurement and calculation, please refer to [link / reference]. Figure 4 and Figure 5 Furthermore, in conjunction with Embodiment 1, the metering mechanism 6 includes a mounting frame 61, which is fixedly installed inside the outer casing 1. A tilting bucket 62 is rotatably mounted on the inner side of the mounting frame 61. A lever 63 is fixedly mounted on the front and back of the tilting bucket 62. Limiting grooves 64 are provided on both the front and back of the mounting frame 61. Contact switches 65 are provided on both sides of the limiting grooves 64. The contact switches 65 are electrically connected to the controller 4. Fixing plates 66 are fixedly installed on the left and right sides of the outer casing 1.

[0035] In actual operation, when this device is used, it is installed outdoors by mounting feet 3. When it rains, rainwater is collected into the outer shell cylinder 1 through the rain inlet 2. The rainwater is initially filtered by the filter cone mesh 513 structure. The filtered rainwater enters the collection hopper 521 and is filtered by the filter cylinder 524 on the collection hopper 521. After filtration, the rainwater is sent to the tilting hopper 62 through the outlet pipe 522. When one side of the tilting hopper 62 is full, it tilts to one side under the action of gravity, and the lever 63 on the tilting hopper 62 touches the contact switch 65 on the corresponding side, sending the rainwater on this side into the drainage hopper 68. The rainwater is discharged through the drainage pipe 67. At the same time, the other side of the tilting hopper 62 tilts upward to continue to receive the rainwater falling from the drainage pipe 67. The above operation is repeated in the same way. By recording the number of times the tilting hopper 62 tilts, the rainfall is calculated.

[0036] When cleaning the filter cone 513 and filter cylinder 524, the threaded cap 514 is rotated to separate it from the threaded post 512. Then, the filter cone 513 is removed and cleaned. Next, the filter cylinder 524 is unscrewed from the retaining ring 523 and cleaned. After cleaning, the filter cylinder 524 is re-threaded back onto the retaining ring 523. Then, the filter cone 513 is installed on the mounting ring 511, and the threaded post 512 passes through the filter cone 513. Finally, the threaded cap 514 is screwed back onto the threaded post 512 for fixation.

[0037] The rainfall is calculated as follows: let the area of ​​the rain inlet 2 be S, and the volume of a single bucket of the tipping bucket 62 be V. Then the rainfall triggered once is h = V / S, and the cumulative rainfall = number of tipping times × h.

[0038] Controller 4 can be a Campbell Scientific CR series (such as CR1000X, CR300).
