Abstract
Description
Technical Field
[0001] This utility model relates to the field of rainfall measurement, and more specifically, to a multi-level linkage rainfall measurement device. Background Technology
[0002] Rainfall gauges are instruments used to measure and record precipitation. They are widely used in meteorology, hydrology, agriculture, flood control, and other fields. Measuring rainfall through these devices provides crucial data support for flood control, disaster reduction, and agricultural development. Most existing rainfall gauges are tipping bucket type, which works by using the alternating tumbling of a mechanical bucket to accumulate rainfall and converting the physical action into an electrical signal output. While tipping bucket rain gauges can measure rainfall, they are costly due to the large number of internal electronic components. Furthermore, they are susceptible to interference from nearby power plants. Since rainy days are often accompanied by lightning, the power generated by lightning can interfere with the electronic components, potentially leading to significant errors in the measurement results. In some cases, lightning strikes could even destroy the electronic components, causing substantial losses. Utility Model Content

[0029] This embodiment discloses a multi-level linkage rainfall metering device, such as... Figure 1 , Figure 2 , Figure 3 As shown, it may include:
[0030] The system includes a rainfall acquisition component 100, a rainfall metering component 200, and a support component 300. The rainfall metering component 200 includes a primary transmission unit and a secondary transmission unit rotatably connected to the rainfall acquisition component 100, and a counting module 270. The primary transmission unit is driven by the secondary transmission unit, and the secondary transmission unit is driven by the counting module 270.
[0031] The support component 300 is detachably and fixedly connected to the rainfall collection component 100.
[0032] In this embodiment, the primary transmission unit and the secondary transmission unit can be rotatably connected to the rain gauge assembly 100 bearing via a bearing rotation connection. To ensure the bearings are not easily corroded by rainwater, existing bearings with a certain degree of waterproofing can be used, or other protective devices (not shown in the figure) can be used to provide special protection for the bearings. In this embodiment, the support assembly 300 can be a frame structure, which may include a support frame and a support plate. The support frame and the support plate are fixedly connected, while the rain gauge assembly 100 is detachably fixedly connected to the support plate. In this embodiment, the detachable fixed connection can be a bolt connection. A rain gauge assembly 200 is provided, and the rain gauge assembly 200 includes components that rotate with the rain gauge assembly 100. The device connects a primary transmission unit, a secondary transmission unit, and a counting module 270; the primary transmission unit is connected to the secondary transmission unit; the secondary transmission unit is connected to the counting module 270. When the multi-stage linkage rain gauge device measures rainfall, the rainfall collected by the rainfall acquisition component 100 can drive the primary transmission unit to rotate, the primary transmission unit can drive the secondary rotation unit to rotate, and the secondary transmission unit can then drive the counting module 270 to rotate, thereby displaying the rainfall. Since the rainfall measurement component 200 has no electronic components and can measure rainfall, it can solve the problem that existing tipping bucket rain gauge devices have many electronic components, are easily affected by lightning interference, and may cause large errors in measurement results, or even be destroyed by lightning, resulting in significant losses.
[0033] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the primary transmission unit includes a first drive module 210, a first gear 220, and a first rotating shaft; the first rotating shaft is detachably and fixedly connected to the first drive module 210 through a central hole on the first drive module 210; the first rotating shaft is detachably and fixedly connected to the first gear 220 through a central hole on the first gear 220; the first rotating shaft is rotatably connected to the rain collection component 100 through a bearing; the first gear 220 is drively connected to the secondary transmission unit.
[0034] In this embodiment, the rainwater collected by the rainwater collection component 100 drives the first drive module 210 to rotate, the first drive module 210 drives the first rotating shaft to rotate, the first rotating shaft drives the first gear 220 to rotate; then the first gear 220 drives the secondary transmission unit to rotate.
[0035] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 4As shown, the first drive module 210 includes a first connecting part 211 and a pushing part 212; the pushing part 212 has a plurality of parts arranged in a circular array along the outer peripheral surface of the first connecting part 211.
[0036] In this embodiment, as Figure 2 , Figure 3 , Figure 4 As shown, it can be imagined that when rainwater falls onto the pusher 212, under the action of gravity, the pusher 212 drives the first connecting part 211 to rotate, and the first connecting part 211 drives the first rotating shaft to rotate; by arranging the pusher 212 in a circular array on the outer circumferential surface of the first connecting part 211, the first connecting part 211 can rotate evenly.
[0037] In some embodiments of this utility model, such as Figure 4 As shown, a water storage tank is provided on the pushing part 212; the water storage tank is recessed from the end face of the pushing part 212 away from the first connecting part 211 to the end face of the pushing part 212 close to the first connecting part 211.
[0038] In this embodiment, by providing a water storage tank on the pushing part 212, rainwater can be collected in the water storage tank to a certain amount before the first connecting part 211 can rotate. This allows the first connecting part 211 to rotate more evenly, thereby obtaining more accurate rainfall measurement data.
[0039] In some embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the secondary transmission unit includes a second gear 230, a second drive module 240, a third drive module 250, a fourth drive module 260, a second rotating shaft, and a positioning shaft. The second rotating shaft is detachably and fixedly connected to the second gear 230 and the second drive module 240 through the center holes on the second gear 230 and the second drive module 240. There are multiple fourth drive modules 260. The positioning shaft is rotatably connected to the third drive module 250 and the fourth drive module 260 through the center holes on the third drive module 250 and the fourth drive module 260. The second rotating shaft is rotatably connected to the rainfall collection component 100 via a bearing; the positioning shaft is detachably fixedly connected to the rainfall collection component 100; the second gear 230 meshes with the first gear 220; the second drive module 240 is drive-connected to the third drive module 250; there are multiple counting modules 270, each counting module 270 being rotatably connected to the second rotating shaft via a central hole; the multiple counting modules 270 are spaced apart, and a fourth drive module 260 is disposed between two adjacent counting modules 270; the fourth drive module 260 is drive-connected to the counting module 270.
[0040] In this embodiment, the first gear 220 and the second gear 230 are meshed together. When the first gear 220 drives the second gear 230 to rotate, the second drive module 240 can rotate with the second shaft. When the second drive module 240 rotates to a predetermined position, it can drive the third drive module 250 to rotate. Subsequently, the third drive module 250 drives the nearby counting module 270 to rotate. The counting module 270 drives the nearby fourth drive module 260 to rotate. When the fourth drive module 260 rotates to a predetermined position, it drives the next counting module 270 to rotate, thereby realizing multi-level linkage measurement of rainfall.
[0041] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 5 As shown, the second drive module 240 includes a second connecting part 241 and a drive shaft 242; the second connecting part 241 is detachably and fixedly connected to the second rotating shaft through a central hole thereon; one end of the drive shaft 242 is fixedly connected to one end face of the second connecting part 241; the drive shaft 242 is connected to the third drive module 250 in a transmission connection.
[0042] In this embodiment, when the second connecting part 241 rotates to a predetermined position, the drive shaft 242 can drive the third drive module 250 to rotate.
[0043] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 6 As shown, the third drive module 250 includes a third connecting part 251 and a plurality of first drive teeth 252; the third connecting part 251 is detachably fixedly connected to the positioning shaft through a central hole thereon; the first drive teeth 252 are evenly arranged on both ends of the third connecting part 251 in a circumferential array; the drive shaft 242 is drivenly connected to the first drive teeth 252 on one end face of the third connecting part 251, and the first drive teeth 252 on the other end face of the third connecting part 251 are drivenly connected to a counting module 270 near the second drive module 240.
[0044] In this embodiment, when the drive shaft 242 rotates to a predetermined position, it can drive the first drive tooth 252 that is close to it to rotate, thereby causing the third drive module 250 to rotate. The first drive tooth 252 connected to the counting module 270 of the third drive module 250 can drive the counting module 270 that is close to the second drive module 240 to rotate.
[0045] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 7As shown, the fourth drive module 260 includes a fourth connecting part 261, a second drive tooth 262, and a third drive tooth 263; the fourth connecting part 261 is rotatably connected to the positioning shaft through a central hole thereon; the second drive tooth 262 is fixedly connected to one end face of the fourth connecting part 261, and there are multiple third drive teeth 263 arranged in a circumferential array and fixedly connected to the other end face of the fourth connecting part 261; two adjacent counting modules 270 are respectively drivenly connected to the second drive tooth 262 and the third drive tooth 263; wherein the third drive tooth 263 is drivenly connected to the end face of the counting module 270 away from the second drive module 240.
[0046] In this embodiment, it can be understood that the previous counting module 270 drives the third driving tooth 263 to rotate, thereby causing the fourth driving module 260 to rotate. When the fourth driving module 260 rotates to a predetermined position, the second driving tooth 262 enables the next counting module 270 to rotate.
[0047] In some embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 8 As shown, the counting module 270 includes a counting section 271 and two gear sections 272; the two gear sections 272 are respectively fixedly connected to the two end faces of the counting section 271; the counting section 271 is uniformly provided with scale values for measuring rainfall on its circumferential surface; the counting module 270 is rotatably connected to the second rotating shaft through its central hole; some of the first drive teeth 252, the second drive teeth 262, and the third drive teeth 263 are connected to the gear sections 272 for transmission.
[0048] In this embodiment, the gear section 272 on the counting module 270 enables the transmission connection between the counting module 270 and a portion of the first drive gear 252, the second drive gear 262, and the third drive gear 263, achieving multi-level linkage. In this embodiment, the scale value used for measuring rainfall is 0-9. However, in some other embodiments, the scale value can be further subdivided to improve measurement accuracy. In this embodiment, it can be understood that the previous measurement value can be used as the initial value for the current measurement. By subtracting the previous measurement value from the current measurement value, the rainfall measurement value for this measurement can be obtained.

The counting module 270 is located on one end face of the first chamber 112, and the scale on the counting module 270 can be observed through the tempered glass 116. The rainfall collection module 120 includes a collection part 121 and a collection part 122. The collection part 121 is flared, with its larger end away from the third chamber 114 and its smaller end fixedly connected to the positioning box 111 at the edge of the third chamber 114. The collection part 122 is fixedly connected to the inner surface of the collection part 121. The distance between the periphery of the collection part 122 and the larger end of the collection part 121 is less than the distance between the center of the collection part 122 and the larger end of the collection part 121. A water inlet is provided at the center of the collection part 122. The water inlet is located directly above the first drive module 210. The first rotating shaft and the second rotating shaft are rotatably connected to the positioning box 111 through bearings. The positioning shaft is detachably fixedly connected to the positioning box 111. The positioning box 111 is detachably fixedly connected to the support assembly 300.
[0050] In this embodiment, the slot 115 is inclined, and the water conveying plate 130 is provided with a groove for water flow. When the water on the pushing part 212 falls onto the water conveying plate 130, it can flow out of the third chamber 114 from the groove of the water conveying plate 130.

[0051] The working principle of this utility model is as follows:
[0052] When rainfall is measured, rainwater is collected by the rainfall collection module 120 and falls onto the pusher 212 of the first drive module 210. During the rotation of the pusher 212, the first gear 220 and the second gear 230 rotate. When the first gear 220 drives the second gear 230 to rotate, the second drive module 240 can rotate with the second shaft. When the second drive module 240 rotates to a predetermined position, it can drive the third drive module 250 to rotate. Then the third drive module 250 drives the nearby counting module 270 to rotate. The counting module 270 drives the nearby fourth drive module 260 to rotate. When the fourth drive module 260 rotates to a predetermined position, it drives the next counting module 270 to rotate. Multi-level linkage rainfall measurement is achieved by changing the scale value on the counting module 270. When the rainfall measurement stops, the counting module 270 can retain the measured value, which can be observed through the tempered glass 116.
