Description

Technical Field

[0001] The present application relates to the field of rainfall monitoring equipment, and in particular to a rain gauge anti-sand and dust cover. Background Art

[0002] A rain gauge is an instrument used to measure precipitation over a specific area over a period of time. In windy and dusty areas, dust can easily enter the rain gauge, damaging the sensor and affecting the accuracy of rainfall measurements.

[0003] To this end, a patent application with patent publication number CN221014766U and application date October 19, 2023 discloses a rain gauge dust cover, including a conical bucket, an arc-shaped filter plate, a cleaning structure and a dust collecting barrel. The arc-shaped filter plate is installed at the opening of the conical bucket, the dust collecting barrel is installed at the bottom of the conical bucket, and the cleaning structure is installed in the conical bucket. Large impurities are filtered through the arc-shaped filter plate, and the dust collecting barrel collects sand and gravel and directly cleans them through the cleaning mechanism.

[0004] After the rainwater enters the above structure and is filtered, it is discharged through the drainage holes on the dust collecting cylinder. After filtering, the rainwater is purer, contains very little sand and has extremely small sand particle size, which has a good protection effect on the rain sensor.

[0005] The dust collecting tube in this solution is installed at the bottom of the conical hopper and has a small mesh. When the rainfall is heavy or there is a lot of rain in the conical hopper, the water pressure at the dust collecting hopper is high and the flow rate of the rain at the mesh is fast. The rain at the bottom of the conical hopper is too dispersed, which is not conducive to the rainfall monitoring of the rain sensor. Utility Model Content

[0006] The present application provides a new anti-sand and dust cover for a rain gauge, which is used to solve the problem that the rainwater is not concentrated and the rain sensor is inconvenient to monitor the rainfall caused by the anti-sand and dust cover.

[0007] The present application provides a new rain gauge anti-sand and dust cover, comprising a cylinder, a conical bucket, a dust collecting cylinder, an arc-shaped filter plate, a rain sensor and a rain collecting plate; the cylinder is provided with an opening on its upper side and a drain outlet on its lower side; the conical bucket is arranged in the cylinder and located at the opening, and a rain outlet is provided at the bottom of the conical bucket; the dust collecting cylinder is arranged in the cylinder and located at the rain outlet of the conical bucket, and a rain leakage mesh is provided on the annular side wall of the dust collecting cylinder; the arc-shaped filter plate is arranged in the cylinder and located on the conical bucket, and the arc-shaped filter plate is arranged on the part of the conical bucket close to the opening; the rain sensor is arranged in the cylinder, and the rain sensor is located at the bottom of the cylinder, and the area where the rain sensor is located is connected to the drain outlet; the rain collecting plate is arranged in the cylinder, and the rain collecting plate is arranged between the rain sensor and the dust collecting cylinder, and a detection hole is provided on the rain collecting plate, and the detection hole passes through the rain collecting plate along the axial direction of the cylinder, and the rain sensor is arranged corresponding to the detection hole.

[0008] The arc filter plate, conical bucket, dust collecting cylinder, rain collecting plate and rain sensor in this application are distributed up and down. The rainwater is first filtered by the arc filter plate to remove larger particle impurities, and then collected into the dust collecting cylinder through the conical bucket. The sand and gravel remain in the dust collecting cylinder, and the rainwater falls on the rain collecting plate along with the leaking mesh, and flows to the rain sensor through the detection hole of the rain collecting plate, so as to prevent the rainwater from falling in different areas due to different water pressure, so that the detection of the rain sensor is more stable and the detection data is more accurate.

[0009] In some embodiments of the present application, the height of the rain collecting plate gradually decreases along the edge of the rain collecting plate toward the detection hole, which facilitates rainwater on the rain collecting plate to flow completely through the detection hole into the rain sensor, thereby facilitating accurate rainfall detection.

[0010] In some embodiments of the present application, the surface height of the rain collecting plate changes linearly along the edge of the rain collecting plate toward the detection hole, and the upper surface of the rain collecting plate is generally curved. This linear change can reduce the possibility of rainwater locally hanging on the wall and promote the smooth flow of rainwater.

[0011] In some embodiments of the present application, a mounting platform is formed on the inner wall of the cylinder extending toward the middle of the cylinder, and the edge of the rain collecting plate overlaps the mounting platform. The overlap between the rain collecting plate and the mounting platform facilitates the installation and removal of the rain collecting plate.

[0012] In some embodiments of the present application, the diameter of the detection hole is larger than the diameter of the rain outlet. A larger diameter of the detection hole can make the detection hole more capable of draining rainwater and prevent rainwater from accumulating on the rain collecting plate and causing rainwater backflow.

[0013] In some embodiments of the present application, the conical hopper is further provided with a drainage hole, which is located outside the rain outlet. A rain shield is formed on the conical hopper, which is fixedly connected to the higher end outside the drainage hole. A gap is provided between the rain shield and the side of the drainage hole closest to the rain outlet, and the drainage hole is projected horizontally onto the rain shield. The drip hole can accelerate the discharge of rainwater when excessive rainwater accumulates in the conical hopper, while allowing rainwater to be transported to the rain outlet through the rain shield when the rainwater is less.

[0014] In some embodiments of the present application, the dust cover of the rain gauge further includes a dust collecting auxiliary tube, which is disposed at the water leakage hole and has a rain leakage mesh provided on the annular side wall of the dust collecting auxiliary tube. The dust collecting auxiliary tube can purify rainwater discharged from the water leakage hole.

[0015] In some embodiments of the present application, multiple drainage holes are provided, spaced apart on the conical bucket; each drainage hole is provided with a rain shield; and each drainage hole is provided with an auxiliary dust collection cylinder. Multiple drainage holes can further improve the drainage capacity of the conical bucket.

[0016] In some embodiments of the present application, the rain shield gradually decreases in height from the edge of the tapered hopper toward the rain outlet, and the angle of inclination of the rain shield is smaller than the taper of the tapered hopper in the area where the rain shield is located. This smaller taper of the rain shield than the taper of the tapered hopper can increase the gap between the rain shield and the leak, facilitating the drainage of heavy rainwater.

[0025] A rain gauge is an instrument used to measure precipitation over a specific area over a period of time. In windy and dusty areas, dust can easily enter the rain gauge, damaging the sensor and affecting the accuracy of rainfall measurements.

[0026] To this end, a patent application with patent publication number CN221014766U and application date October 19, 2023 discloses a rain gauge dust cover, including a conical bucket, an arc-shaped filter plate, a cleaning structure and a dust collecting barrel. The arc-shaped filter plate is installed at the opening of the conical bucket, the dust collecting barrel is installed at the bottom of the conical bucket, and the cleaning structure is installed in the conical bucket. Large impurities are filtered through the arc-shaped filter plate, and the dust collecting barrel collects sand and gravel and directly cleans them through the cleaning mechanism.

[0027] After the rainwater enters the above structure and is filtered, it is discharged through the drainage holes on the dust collecting cylinder. After filtering, the rainwater is purer, contains very little sand and has extremely small sand particle size, which has a good protection effect on the rain sensor.

[0028] The dust collecting tube in this solution is installed at the bottom of the conical hopper and has a small mesh. When the rainfall is heavy or there is a lot of rain in the conical hopper, the water pressure at the dust collecting hopper is high and the flow rate of the rain at the mesh is fast. The rain at the bottom of the conical hopper is too dispersed, which is not conducive to the rainfall monitoring of the rain sensor.

[0029] To do this, please refer to Figure 1 The present application provides a new anti-sand and dust cover for a rain gauge, comprising a cylinder 1, a conical bucket 2, a dust collecting cylinder 3, an arc-shaped filter plate 4, a rain sensor 5 and a rain collecting plate 6.

[0030] Please refer to Figure 1The cylinder 1 has an opening on its upper side and a drain outlet on its lower side. The cylinder 1 can be the cylinder 1 of a rain gauge, and its material can be metal or plastic, and its shape can be cylindrical or prismatic.

[0031] Please refer to Figure 1 The conical bucket 2 is arranged in the cylinder 1 and is located at the opening 11. The bottom of the conical bucket 2 is provided with a rain outlet 21. The conical bucket 2 can be made of plastic or metal. The conical bucket 2 and the inner wall of the cylinder 1 can be connected by a clip or a bolt. The rain outlet 21 can be a circular hole or a square hole.

[0032] Please refer to Figure 1 The dust collecting barrel 3 is disposed within the barrel body 1 and is located at the rain outlet 21 of the conical hopper 2. A rain leakage mesh 31 is provided on the annular sidewall of the dust collecting barrel 3. The dust collecting barrel 3 can be snap-fitted to the conical hopper 2, or alternatively, can be sealed and fixedly connected. The conical hopper 2 can be removed to clean the sand and gravel in the dust collecting barrel 3. The aperture of the rain leakage mesh 31 can be smaller than that of the sand and gravel to facilitate blocking the sand and gravel. A plurality of rain leakage mesh 31 can be provided, which can be distributed throughout the sidewall of the dust collecting barrel 3, or can be arranged in a predetermined area.

[0033] Please refer to Figure 1 The curved filter plate 4 is disposed within the cylinder 1 and positioned on the conical hopper 2. The curved filter plate 4 is disposed on the portion of the conical hopper 2 near the opening 11. The aperture of the curved filter plate 4 can be larger than the aperture of the rainwater leakage mesh 31 to facilitate blocking larger impurities. The curved filter plate 4 and the conical hopper 2 can be connected by a snap or fixed connection.

[0034] Please refer to Figure 1 The rain sensor 5 is disposed within the cylinder 1 and is located at the bottom of the cylinder 1. The area where the rain sensor 5 is located is connected to the drain outlet 12. The rain sensor 5 can be a tipping bucket rain sensor 5 or other rain sensor 5. The rain sensor 5 can be part of the rain gauge and is only used here to illustrate its positional relationship with other structures within the dust cover.

[0035] Please refer to Figure 1 A rain collecting plate 6 is disposed within the cylinder 1, between the rain sensor 5 and the dust collecting cylinder 3. A detection hole 61 is provided on the rain collecting plate 6, which passes through the rain collecting plate 6 along the axis of the cylinder 1. The rain sensor 5 is disposed corresponding to the detection hole 61. The rain collecting plate 6 may be a metal plate or a non-metal plate, and may be welded to the inner wall of the cylinder 1 or connected in other ways.

[0036] Please refer to Figure 1In this application, the arc filter plate 4, conical bucket 2, dust collecting tube 3, rain collecting plate 6 and rain sensor 5 are distributed up and down. The rainwater is first filtered by the arc filter plate 4 to remove larger particle impurities, and then collected by the conical bucket 2 into the dust collecting tube 3. The gravel remains in the dust collecting tube 3, and the rainwater falls on the rain collecting plate 6 along the leaking mesh 31, and flows to the rain sensor 5 through the detection hole 61 of the rain collecting plate 6, so as to prevent the rainwater from falling in different areas due to different water pressure, so that the detection of the rain sensor 5 is more stable and the detection data is more accurate.

[0037] Please refer to Figure 1 In some examples, the height of the rain collecting plate 6 gradually decreases along the edge of the rain collecting plate 6 toward the detection hole 61. This allows rainwater on the rain collecting plate 6 to flow completely through the detection hole 61 into the rain sensor 5, facilitating accurate rainfall detection.

[0038] In some examples, the overall inclination angle of the rain collecting plate 6 can be between 30° and 45°, preferably 30°. A gap can be provided between the rain collecting plate 6 and the conical bucket 2, and the gap height can be greater than or equal to the height of the conical bucket 2 along the axis of the cylinder 1.

[0039] Please refer to Figure 1 In some examples, the height of the rain collecting plate 6 varies linearly along the edge of the plate 6 toward the detection hole 61, and the upper surface of the plate 6 is generally curved. This linear variation reduces the likelihood of rainwater clinging to the wall and facilitates smoother flow of rainwater.

[0040] In some examples, along the edge of the rain collecting plate 6 pointing to the detection hole 61, the cross section of the rain collecting plate 6 can be a straight line, a curve, or can include both straight lines and curves, and the connection between the straight lines and the curves is smoothly transitioned through rounded corners.

[0041] Please refer to Figure 1 In some examples, a mounting platform 13 is formed on the inner wall of the cylinder 1 and extends toward the middle of the cylinder 1, and the edge of the rain collecting plate 6 overlaps the mounting platform 13. The rain collecting plate 6 overlaps the mounting platform 13 to facilitate the installation and removal of the rain collecting plate 6.

[0042] In some examples, there can be one or more mounting platforms 13. When there is one mounting platform 13, the mounting platform 13 can surround the inner wall of the cylinder 1. When there are multiple mounting platforms 13, the multiple mounting platforms 13 can be the same or different.

[0043] Please refer to Figure 1 In some examples, the diameter of the detection hole 61 is larger than the diameter of the rain outlet 21. The larger diameter of the detection hole 61 can make the detection hole 61 more capable of draining rain, thereby preventing rainwater from accumulating on the rain collecting plate 6 and causing rainwater backflow.

[0044] In some examples, the diameter of the detection hole 61 may be 1.5 times or 2 times the diameter of the rain outlet 21. The diameter here may refer to the cross-sectional area of ​​the detection hole 61 and the rain outlet 21, or the detection hole 61 and the rain outlet 21 may both be circular holes, with the diameter referring to their radius or diameter.

[0045] Please refer to Figure 1 In some examples, a water leakage hole 22 is further provided on the conical bucket 2, and the water leakage hole 22 is provided outside the rain outlet 21; a rain shield 23 is formed on the conical bucket 2, and the rain shield 23 is fixedly connected to the higher end outside the water leakage hole, and a gap is provided between the rain shield 23 and the side of the water leakage hole close to the rain outlet 21, and the water leakage hole 22 is projected onto the rain shield 23 in the horizontal direction.

[0046] The drip hole can speed up the transportation of rainwater when too much rainwater accumulates in the conical bucket 2, and can transport the rainwater to the rain outlet 21 through the rain shield 23 when there is less rainwater.

[0047] In some examples, the water leakage hole 22 can be a circular hole or a square hole. The rain shield 23 can be connected to the conical bucket 2 by snapping, welding or fixed connection.

[0048] Please refer to Figure 1 In some examples, the dust cover of the rain gauge further includes a dust collecting auxiliary tube 7, which is disposed at the water leakage hole 22 and has a rain leakage mesh 31 disposed on the annular side wall of the dust collecting auxiliary tube 7. The dust collecting auxiliary tube 7 can purify rainwater discharged from the water leakage hole.

[0049] In some examples, the auxiliary dust collection cylinder 7 may be the same as or similar to the dust collection cylinder 3 .

[0050] Please refer to Figure 1 In some examples, multiple drainage holes are provided, and the multiple drainage holes are spaced apart on the conical hopper 2; each drainage hole is provided with a rain shield 23; and each drainage hole is provided with a dust collecting auxiliary cylinder 7. Multiple drainage holes can further improve the drainage capacity of the conical hopper 2.

[0051] In some examples, the number of the water leakage holes may be 1 to 3, preferably 3, and the three water leakage holes may be equally spaced around the rain outlet 21 .

[0052] Please refer to Figure 1 In some examples, the height of the rain shield 23 gradually decreases from the edge of the conical hopper 2 toward the rain outlet 21, and the inclination angle of the rain shield 23 is smaller than the taper of the conical hopper 2 in the area where the rain shield 23 is located. The smaller taper of the rain shield 23 than the taper of the conical hopper 2 can increase the gap between the rain shield 23 and the leak, facilitating the drainage of heavy rainwater.

[0053] Please refer to Figure 1 In some examples, the inclination angle of the rain shield 23 can be close to the taper of the conical bucket 2 in the area where the rain shield 23 is located, and the difference can be 3° to 5°, so that the rainwater on the rain shield 23 flows faster.

[0054] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0055] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
