Description

Technical Field

[0001] The present application relates to the field of meteorological humidity and rainfall detection, and in particular to a humidity and rainfall integrated meteorological instrument. Background Art

[0002] The humidity and rainfall integrated meteorological instrument is a meteorological instrument that integrates humidity and rainfall measurement functions. It is usually used in meteorological observation, environmental testing, agriculture, water conservancy and other fields, and can measure and record meteorological parameters such as air humidity and rainfall in real time.

[0003] The humidity and rainfall integrated meteorological instrument generally includes a rain gauge and a humidity sensor, which are independently set and separated by a partition. The rain gauge is usually set at the top of the device, and the humidity sensor and humidity detection window are set at the bottom.

[0027] The humidity and rainfall integrated meteorological instrument is a meteorological instrument that integrates humidity and rainfall measurement functions. It is usually used in meteorological observation, environmental testing, agriculture, water conservancy and other fields, and can measure and record meteorological parameters such as air humidity and rainfall in real time.

[0028] The humidity and rainfall integrated meteorological instrument generally includes a rain gauge and a humidity sensor, which are independently set and separated by a partition. The rain gauge is usually set at the top of the device, and the humidity sensor and humidity detection window are set at the bottom. During installation, a rain cover needs to be set on the humidity sensor to prevent rain from entering the humidity sensor and affecting the detection data.

[0029] The rain cover is usually snapped or glued to the outer shell of the humidity and rainfall integrated meteorological instrument, and the cover is connected to the air inlet of the humidity sensor. However, a drainage window is usually set at the bottom of the rain gauge. The water flow out of the drainage window is large. When the rainwater discharged from the drainage window hits the rain cover, it will destroy the stability of the rain cover, thereby causing water to enter the humidity sensor and destroying the humidity detection accuracy of the humidity and rainfall integrated meteorological instrument.

[0030] To do this, please refer to Figure 1 The present application provides a humidity and rainfall integrated meteorological instrument, comprising a housing 1, a rain gauge 2, a humidity detection module 3 and a rainproof pipe 4.

[0031] Please refer to Figure 1 The housing 1 may be a metal housing 1 or a plastic housing 1, the partition 11 may be integrally formed with the housing 1 or may be welded, and the partition 11 is sealed and connected to the inner wall of the housing 1 so that the upper cavity 12 and the lower cavity 13 are relatively independent. The upper and lower may be the position distribution relationship of the housing 1 in the installed state.

[0032] Please refer to Figure 1 The rain gauge 2 is arranged on the partition 11 and is located in the upper cavity 12.

The drainage window 14 can be arranged at the bottom of the upper cavity 12, and the bottom of the drainage window 14 can abut against the top surface of the partition 11 to improve the drainage effect. One drainage window 14 can be arranged, or multiple drainage windows 14 can be arranged.

The rainproof pipe 4 can be a metal pipe or a plastic pipe, and the rainproof pipe 4 can be a round pipe.

[0036] Please refer to Figure 1 The air inlet 41 may be arranged downward so that the axis of the air inlet 41 is directed downward, or the axis of the air inlet 41 may form an angle with the vertical direction, and the angle may be between 0° and 15°.

[0037] Please refer to Figure 1 The air inlet 15 of the housing 1 is provided with a second connection part 5, and the first connection part 6 is fixedly connected to the second connection part 5. The first connection part 6 and the second connection part 5 can be welded, threaded or clamped.

[0038] The rain gauge 2 and humidity detection module 3 in the present application are both arranged in the outer shell 1. While the rain gauge 2 and the humidity detection module 3 are working normally, a rainproof pipe 4 is arranged at the air inlet 15 of the humidity detection module 3. The air inlet 41 of the rainproof pipe 4 faces downward to prevent rainwater from entering the rainproof pipe 4, and then prevents it from entering the lower cavity 13, which can provide protection for the detection result of the humidity detection module 3; on the other hand, the fixed connection between the second connecting part 5 and the first connecting part 6 can make the connection between the rainproof pipe 4 and the outer shell 1 stable, thereby providing further protection for the operation of the humidity detection module 3.

[0039] Please refer to Figure 2 In some examples, the first connecting portion 6 includes a plurality of annular clamping protrusions 61, which are arranged at the end of the rainproof pipe 4, and a gap is formed between two adjacent annular clamping protrusions 61, and the central angle of the gap is greater than or equal to the central angle of the annular clamping protrusion 61; the second connecting portion 5 includes an extension portion 51, the extension portion 51 is annular, and a circular accommodating hole is arranged in the extension portion 51, and the rainproof pipe 4 extends into the circular accommodating hole, and an annular limiting hole 511 is arranged on the inner ring wall of the extension portion 51, and the opening of the annular limiting hole 511 faces the inner side of the extension portion 51; a plurality of annular notches 512 are arranged on the extension portion 51, and along the cross section perpendicular to the axis of the extension portion 51, the area of ​​each annular notch 512 is greater than or equal to the area of ​​each annular clamping protrusion 61.

[0040] Please refer to Figure 2 The annular clamping protrusion 61 can extend into the annular notch 512 and be screwed into the annular limiting hole 511, so that the inner wall of the annular limiting hole 511 faces the annular clamping protrusion 61 for limiting the position, thereby limiting the drain pipe, making the connection between the rainproof pipe 4 and the outer shell 1 stable, and preventing the rainproof pipe 4 from detaching from the outer shell 1 due to wind and rain or water flow from the drainage window 14.

[0041] Please refer to Figure 2 For example, the annular snap-fit ​​protrusion 61 can be integrally formed with the rainproof pipe 4 to form a structure similar to a pipe joint. Multiple annular snap-fit ​​protrusions 61 can be spaced apart around the axis of the rainproof pipe 4, or the annular snap-fit ​​protrusions 61 can be arc-shaped, block-shaped, or plate-shaped. While multiple annular snap-fit ​​protrusions 61 are spaced apart around the axis of the rainproof pipe 4, they can also be spaced along the axis of the rainproof pipe 4.

[0042] Please refer to Figure 2 The number of annular notches 512 may correspond to the number of annular snap-fit ​​protrusions 61 , so that each annular snap-fit ​​protrusion 61 extends into an annular notch 512 , and the arc angle of the annular notch 512 may be greater than or equal to the arc angle of the corresponding annular snap-fit ​​protrusion 61 .

[0043] In some examples, different annular snap-fit ​​protrusions 61 may be the same or different.

[0044] Please refer to Figure 2 In some examples, the extension part 51 can be integrally formed with the housing 1, or can be welded or bolted. The extension part 51 can be made of metal, can be block-shaped, and can be provided with a circular receiving space in the middle to form the above structure, or can be other shapes.

[0045] In some examples, the humidity and rainfall integrated meteorological instrument further includes a fastener, which is disposed on the annular clamping protrusion 61 and the extension portion 51, and the fastener connects the annular clamping protrusion 61 and the extension portion 51. The fastener can further improve the stability between the annular clamping protrusion 61 and the extension portion 51, thereby making the connection between the rainproof pipe 4 and the housing 1 more stable.

[0046] Exemplarily, the fastener may be a bolt, or a screw, or a rivet.

[0047] In some examples, mounting holes may be reserved on the annular clamping protrusion 61 and the extension portion 51 , or a fixed connection effect may be achieved by self-tapping.

[0048] In some examples, at least one fastener is disposed on each annular clamping protrusion 61. In this case, the connection between each annular clamping protrusion 61 and the corresponding extension portion 51 can be made more stable, further improving the connection strength between the housing 1 and the rainproof pipe 4.

[0049] In some examples, the number of fasteners on each annular clamping protrusion 61 may be one, two, or three.

[0050] Please refer to Figure 3In some examples, the first connection part 6 is configured as an external thread 42, which is disposed on the outer ring wall of the rainproof pipe 4; the second connection part 5 is configured as a threaded hole, the internal thread 16 of the threaded hole is disposed on the inner wall of the air inlet 15, and the first connection part 6 is threadedly connected to the second connection part 5. The threaded connection can stabilize the connection between the rainproof pipe 4 and the housing 1.

[0051] Please refer to Figure 3 At this time, the thickness of the inner wall of the air inlet 15 of the housing 1 is not enough to meet its installation conditions, and an external component can be welded on the housing 1, and the length of the internal thread 16 can be achieved through the external component.

[0052] In some examples, the humidity and rainfall integrated meteorological instrument further includes a waterproof layer, which is disposed between the first connecting portion 6 and the second connecting portion 5. The waterproof layer can further improve the waterproof performance of the lower cavity 13 of the housing 1.

[0053] Exemplarily, the waterproof layer may be a waterproof tape, and wrapping the waterproof tape around the threaded connection may improve the waterproof effect after the threads are mated.

[0054] In some examples, the rainproof pipe 4 is a straight pipe, one end of the rainproof pipe 4 is open, the other end of the rainproof pipe 4 is closed, the opening of the rainproof pipe 4 is connected to the housing 1 and the opening is connected to the air inlet 15, and the air inlet 41 is arranged on the bottom side wall of the rainproof pipe 4. This method can make the rainproof pipe 4 have a good defense effect and provide rain protection for the lower cavity 13.

[0055] Exemplarily, the opening may be a circular opening, a square opening, or an irregular-shaped opening.

[0056] In some other examples, the rainproof pipe 4 is a curved pipe, and both ends of the rainproof pipe 4 are provided with openings, one end opening of the rainproof pipe 4 is connected to the air inlet 15, and the other end opening of the rainproof pipe 4 faces downward and is the air inlet 41. This method can make the rainproof pipe 4 have a good defense effect and provide rain protection for the lower cavity 13.

[0057] Exemplarily, the curved pipe may be bent in one section, or may be bent in multiple sections. When the curved pipe is bent in multiple sections, the opening of the rainproof pipe 4 may still be arranged downward to ensure its rainproof effect.

[0058] Please refer back to Figure 1 In some examples, the humidity and rainfall integrated meteorological instrument further includes an insect-proof net 7, which is disposed at the air inlet 41. The insect-proof net 7 can prevent insects from entering the rainproof pipe 4 from the air inlet 41, and provide insect-proof protection for the humidity detection module 3.

[0059] In some examples, the insect-proof net 7 may be a metal net or a plastic net.

[0060] 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.

[0061] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
