Description

Technical Field

[0001] The present application relates to the field of tipping bucket rain gauges, and in particular to an anti-clogging tipping bucket rain gauge device. Background Art

[0002] The tipping bucket rain gauge is an important rainfall observation instrument that can observe rainfall data in real time and digitally. It has the advantages of accurate time, automatic data recording and easy data collection, compilation and processing.

[0003] The tipping bucket rain gauge installed outdoors usually includes a housing, a rain collecting bucket, a tipping bucket metering component, and a counting component to measure rainfall. In order to prevent leaves from entering the rain collecting bucket and blocking the rainwater channel, a filter screen is set on the rain collecting bucket to prevent leaves from falling in.

[0004] However, rainwater will be mixed with dust and impurities, and the tipping bucket rain gauge located in the forest area will be more susceptible to impurities, thereby blocking the leakage of the rain collecting bucket near the tipping bucket metering component, causing the rain gauge to fail to work properly. Summary of the invention

[0005] The present application provides an anti-clogging tipping bucket rain gauge device, which is used to solve the problem that the rain gauge cannot work normally due to the blockage of the water inlet of the tipping bucket rain gauge.

[0006] The present application provides an anti-clogging tipping bucket rain gauge device, comprising an outer shell, a rain collecting bucket, a rain gauge metering assembly and a partition net, wherein a mounting hole is formed on the top wall of the outer shell; the rain collecting bucket comprises a funnel and a conduit, the funnel is sealedly connected to the conduit and the funnel and the conduit are distributed up and down, and the funnel is arranged at the mounting hole; the rain gauge metering assembly is arranged in the outer shell and is located below the conduit, and the rain outlet of the conduit is connected to the tipping bucket in the rain gauge metering assembly; the partition net is arranged in the funnel and on the part of the funnel located outside the outer shell; wherein the conduit comprises a first part and a second part, the first part and the second part are distributed along a turning direction perpendicular to the tipping bucket, the first part is fixedly connected to the funnel, the second part is rotationally connected to the funnel, and the first part and the second part are abutted against each other.

[0007] The rain collecting bucket in the present application is used to receive and transfer rainwater. When there are many debris in the rainwater, it is easy to block the conduit. At this time, the water flow rate in the rain collecting bucket will decrease, so that the water level in the rain collecting bucket rises and the pressure at the conduit rises. The water pressure can compel the second part to rotate around the funnel, thereby increasing the water flow cross section, thereby flushing the inner wall of the conduit and flushing away the obstruction, avoiding the conduit from being blocked and affecting the rain gauge function. This solution can avoid the conduit blockage affecting the rain gauge capacity of the tipping bucket rain gauge, and help the outdoor tipping bucket rain gauge that is difficult to maintain and has a low maintenance frequency to work stably for a long time.

[0008] In some embodiments of the present application, the rain collecting hopper further includes an elastic stopper, which is disposed on the outer wall of the hopper, is fixedly connected to the hopper, and abuts against the second part, and is used to abut the second part against the first part. The elastic stopper can form an elastic resistance force between the second part and the hopper, thereby ensuring the abutment stability between the first part and the second part, and can reset the second part when the water pressure in the rain collecting hopper decreases, so that the tipping bucket rain gauge returns to a normal working state.

[0009] In some embodiments of the present application, the elastic stopper includes a torsion spring and two arc-shaped baffles, the two arc-shaped baffles are respectively arranged on the outer wall of the funnel and the outer wall of the second part, and the two torsion parts of the torsion spring are respectively fixedly connected to the two arc-shaped baffles. The arc-shaped baffle can improve the connection strength between the torsion spring and the second part and the funnel, and ensure the stability of the connection. The torsion spring can provide an elastic force between the second part and the funnel.

[0010] In some embodiments of the present application, a clamping recess and a clamping protrusion are provided between the first part and the second part, and the clamping recess and the clamping protrusion are clamped. The clamping between the first part and the second part can form a more complete water flow channel between the first part and the second part, thereby preventing water from flowing out of the receiving area of ​​the tipping bucket along the gap between the first part and the second part, and ensuring the measurement accuracy of the tipping bucket type rain gauge.

[0011] In some embodiments of the present application, the snap-in recess is disposed on the first part, and the snap-in protrusion is disposed on the second part. The arrangement of the snap-in recess and the snap-in protrusion can meet the snap-in requirements of the first part and the second part.

[0012] In some embodiments of the present application, two clamping recesses and two clamping protrusions are provided. The two clamping recesses and two clamping protrusions can enable the two contact edges of the first part and the second part to have a good abutment effect.

[0013] In some embodiments of the present application, a drain port is formed on the bottom wall of the housing, which can drain rainwater in the tipping bucket rain gauge, so that the tipping bucket rain gauge can work stably for a long time.

[0014] In some embodiments of the present application, a convex plate is provided on the outer wall of the funnel, a groove is formed in the mounting hole of the shell, and the convex plate extends into the groove so that the rain collecting hopper is clamped with the shell. The convex plate can be clamped with the groove to form a stable connection relationship between the convex plate and the groove.

[0016] In some embodiments of the present application, an annular depression is formed in the funnel, and the partition net is arranged in the annular depression. The partition net is clamped in the annular depression to improve the stability of the partition net and prevent the partition net from being bounced out of the rain collecting hopper due to its own elasticity when the water flow is too large or hail weather occurs.

[0028] The tipping bucket rain gauge is an important rainfall observation instrument that can observe rainfall data in real time and digitally. It has the advantages of accurate time, automatic data recording and easy data collection, compilation and processing.

[0029] The tipping bucket rain gauge installed outdoors usually includes a housing, a rain collecting bucket, a tipping bucket metering component, and a counting component to measure rainfall. In order to prevent leaves from entering the rain collecting bucket and blocking the rainwater channel, a filter screen is set on the rain collecting bucket to prevent leaves from falling in.

[0030] However, rainwater will be mixed with dust and impurities, and the tipping bucket rain gauge located in the forest area will be more susceptible to impurities, thereby blocking the leakage of the rain collecting bucket near the tipping bucket metering component, causing the rain gauge to fail to work properly.

[0031] To do this, please refer to Figure 1 The present application provides a rain gauge device with an anti-clogging tipping bucket 31, comprising a housing 1, a rain collecting bucket 2, a rain gauge assembly 3 and a partition net 4.

[0032] Please refer to Figure 1 The top wall of the housing 1 is provided with a mounting hole 11. The housing 1 may be a housing 1 of a conventional tipping bucket 31 type rain gauge, and its material may be plastic or metal. The mounting hole 11 is used to mount the rain collecting bucket 2, which is a conventional structure on the housing 1; the mounting hole 11 may be a circular hole, or a square hole or a special-shaped hole.

[0033] Please refer to Figure 1 The rain collecting hopper 2 includes a funnel 21 and a conduit 22. The funnel 21 is sealed and connected to the conduit 22 and the funnel 21 and the conduit 22 are arranged up and down. The funnel 21 is arranged at the mounting hole 11. The funnel 21 may include a cylindrical structure and a conical structure at the top. The conduit 22 may be formed by a cylindrical structure at the lower side of the conical structure or a conical structure with a larger taper. The funnel 21 and the conduit 22 may be integrally formed, or may be welded or bonded, which may meet the use requirements.

[0034] Please refer to Figure 1 For example, the rain collecting bucket 2 is vertically arranged, and the up-down distribution here can be understood as the up-down direction when the rain collecting bucket 2 is working, that is, the up-down distribution in the gravity direction. The funnel 21 can be placed at the mounting hole 11, and at this time, it can be bonded, welded, clamped or threaded or bolted, all of which can make the funnel 21 meet the working needs.

[0035] Please refer to Figure 1 The rain gauge assembly 3 is arranged in the housing 1 and is located below the conduit 22. The rain outlet of the conduit 22 is connected to the tipping bucket 31 in the rain gauge assembly 3. The rain gauge assembly 3 is a conventional tipping bucket 31 type metering assembly, a reed switch and a counting assembly. The tipping bucket 31 can be a tipping bucket 31 structure in a tipping bucket 31 type metering assembly, which is a common structure in a conventional tipping bucket 31 type rain gauge device and will not be described in detail here.

[0036] Please refer to Figure 1 The partition net 4 is arranged in the funnel 21 and on the part of the funnel 21 outside the housing 1. The partition net 4 can be made of metal or plastic, both of which can meet the use requirements. A certain gap can be set between the partition net 4 and the top wall of the funnel 21 to prevent rainwater from overflowing and affecting the measurement result when the water leakage rate of the partition net 4 is lower than the rain speed, and to prevent fallen leaves from being washed out by rainwater and blocking the funnel 21 when the partition net 4 is too deep.

[0037] Please refer to Figure 1The conduit 22 includes a first part 221 and a second part 222, the first part 221 and the second part 222 are distributed along a flipping direction perpendicular to the tipping bucket 31, the first part 221 is fixedly connected to the funnel 21, the second part 222 is rotatably connected to the funnel 21, and the first part 221 and the second part 222 are abutted against each other.

[0038] Please refer to Figure 1 The rain collecting bucket 2 in the present application is used to receive and transfer rainwater. When there are many debris in the rainwater, it is easy to block the conduit 22. At this time, the water flow rate in the rain collecting bucket 2 will decrease, so that the water level in the rain collecting bucket 2 rises and the pressure at the conduit 22 rises. The water pressure can compel the second part 222 to rotate around the funnel 21, thereby increasing the water flow cross-section, thereby flushing the inner wall of the conduit 22, flushing away the obstruction, and avoiding the conduit 22 from being blocked and affecting the rain gauge function. This solution can prevent the conduit 22 from being blocked and affecting the rain gauge ability of the tipping bucket 31 rain gauge, and help the outdoor tipping bucket 31 rain gauge, which is difficult to maintain and has a low maintenance frequency, to work stably for a long time.

[0039] Please refer to Figure 1 In some examples, the first part 221 and the second part 222 of the conduit 22 can be independent structures. In this case, the first part 221 and the second part 222 can be the same structure, that is, the first part 221 and the second part 222 can both be a semi-cylindrical tube body, and a complete circular tube is formed by abutting between the first part 221 and the second part 222, and the function of guiding flow is realized.

[0040] Please refer to Figure 1 Alternatively, the first part 221 and the second part 222 may have different structures. For example, when the first part 221 and the second part 222 together form a circular tube, the first part 221 may account for a larger proportion, and the central angle of the first part 221 may be greater than the circular angle of the second part 222. In this case, the first part 221 and the second part 222 may also form a circular tube together.

[0041] Please refer to Figure 1 In some examples, the first part 221 and the second part 222 may be in contact with each other. When in contact with each other, a corresponding frosted surface may be provided between the first part 221 and the second part 222 to increase the friction and water flow resistance between the first part 221 and the second part 222, and reduce the possibility that rainwater overflows from the gap between the first part 221 and the second part 222 and affects the metering result.

[0042] In some examples, the first portion 221 and the funnel 21 may be integrally formed, and in this case, a fixed connection relationship between the first portion 221 and the funnel 21 may be achieved.

[0043] Alternatively, the first part 221 and the funnel 21 may also be welded or bonded, which can also meet the functional requirements of the first part 221 required by the present application.

[0044] Please refer to Figure 1 In some examples, the second part 222 and the funnel 21 are rotatably connected, and the rotatable connection structure can be connected by a hinge or a hinge. In this case, a corresponding hinge seat can be provided outside the funnel 21 for installing the hinge to ensure the strength of the funnel 21 and the sealing between the funnel 21 and the second part 222.

[0045] Please refer to Figure 2 In some examples, the rain collecting hopper 2 further includes an elastic stopper 23, which is disposed on the outer wall of the hopper 21, is fixedly connected to the hopper 21, and abuts against the second portion 222, and is used to abut the second portion 222 against the first portion 221. The elastic stopper 23 can form an elastic resistance force between the second portion 222 and the hopper 21, thereby ensuring the abutment stability between the first portion 221 and the second portion 222, and can also reset the second portion 222 when the water pressure in the rain collecting hopper 2 is reduced, so that the tipping bucket 31 type rainfall gauge returns to a normal working state.

[0046] Please refer to Figure 2 In some examples, the elastic stopper 23 includes a torsion spring 231 and two arc-shaped baffles 232, the two arc-shaped baffles 232 are respectively arranged on the outer wall of the funnel 21 and the outer wall of the second part 222, and the two torsion parts of the torsion spring 231 are respectively fixedly connected to the two arc-shaped baffles 232. The arc-shaped baffles 232 can improve the connection strength between the torsion spring 231 and the second part 222 and the funnel 21, and ensure the stability of the connection. The torsion spring 231 can provide an elastic force between the second part 222 and the funnel 21.

[0047] Please refer to Figure 2 In some examples, the curvature of the arc baffle 232 may be the same as the curvature of its contact surface, that is, the arc baffle 232 may be attached to the funnel 21 or the second portion 222. The arc baffle 232 may be an arc plate with the same thickness everywhere, or may be an arc plate with unequal thicknesses, in which case one side wall of the arc baffle 232 may be arc-shaped, and the other side wall corresponding to the arc side wall may be a plane.

[0048] Please refer to Figure 2 In some examples, the torsion spring 231 may be a conventional torsion spring 231 , which only needs to provide elastic force between the funnel 21 and the second part 222 .

[0049] In some examples, the torsional force of the torsion spring 231 can be approximately equal to the pressure when the water level in the funnel 21 is two-thirds of the height of the funnel 21. At this time, the rainwater in the funnel 21 can provide pressure for the inner wall of the second part 222, thereby increasing the cross-section of the conduit 22 to impact blockages or speed up the metering speed.

[0050] In some examples, the torsion spring 231 may be fixedly connected to the outer wall of the funnel 21 and elastically abut against the outer wall of the second portion 222 .

[0051] Please refer to Figure 3 In some examples, a snap-in recess 223 and a snap-in protrusion 224 are provided between the first part 221 and the second part 222, and the snap-in recess 223 is snap-fitted with the snap-in protrusion 224. The snap-in connection between the first part 221 and the second part 222 can form a more complete water flow channel between the first part 221 and the second part 222, thereby preventing water from flowing out of the receiving area of ​​the tipping bucket 31 along the gap between the first part 221 and the second part 222, and ensuring the measurement accuracy of the tipping bucket 31 type rain gauge.

[0052] Please refer to Figure 3 In some examples, the snap-in recess 223 is disposed on the first portion 221, and the snap-in protrusion 224 is disposed on the second portion 222. The arrangement of the snap-in recess 223 and the snap-in protrusion 224 can meet the snap-in requirements of the first portion 221 and the second portion 222 described above.

[0053] Please refer to Figure 3 In some examples, the number of the clamping recess 223 and the number of the clamping protrusion 224 are both two. The two clamping recesses 223 and the two clamping protrusions 224 can make the two contact edges of the first part 221 and the second part 222 have a good abutment effect.

[0054] In some examples, a drain port is formed on the bottom wall of the housing 1. The drain port can drain rainwater in the tipping bucket 31 type rain gauge, so that the tipping bucket 31 type rain gauge can work stably for a long time.

[0055] Please refer back to Figure 1 In some examples, a convex plate 211 is provided on the outer wall of the funnel 21, a groove 12 is formed at the mounting hole 11 of the housing 1, and the convex plate 211 extends into the groove 12 so that the rain collecting hopper 2 is snap-fitted with the housing 1. The convex plate 211 can be snap-fitted with the groove 12, so that a stable connection relationship is formed between the convex plate 211 and the groove 12.

[0056] In some examples, a plurality of convex plates 211 are provided, and the plurality of convex plates 211 are spaced apart around the axis of the rain collecting hopper 2, and a plurality of grooves 12 are provided, and the plurality of grooves 12 correspond one to one to the plurality of convex plates 211. The plurality of convex plates 211 and the plurality of grooves 12 can improve the connection strength between the rain collecting hopper 2 and the housing 1, and improve the stability of the rain collecting hopper 2.

[0057] Please refer to Figure 4 In some examples, an annular depression 212 is formed in the funnel 21, and the partition net 4 is disposed in the annular depression 212. The partition net 4 is clamped in the annular depression 212 to improve the stability of the partition net 4 and prevent the partition net 4 from being ejected out of the rain collecting hopper 2 due to its own elasticity when the water flow is too large or hail weather occurs.

[0058] 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.

[0059] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto.
