Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] A rain gauge detector for an automatic weather station comprises: a main body, a base 1, a rain receiver 11 is mounted on the surface of the base 1, a mounting bracket 12 and a bracket 13 are fixedly connected to the surface of the base 1, a funnel 14 is fixedly connected to the surface of the bracket 13, a tipping bucket 15 is movably connected to the surface of the bracket 13, a filter plate 16 is mounted on the inner surface of the rain receiver 11, when the rain gauge is used to detect rainfall, rainwater is collected from the rain receiver 11, and the collected rainwater passes through the funnel 14 and falls into the tipping bucket 15, and a magnet is arranged on the tipping bucket 15, a reed switch is mounted on the bracket 13, and the magnet is close to the reed switch and away from the reed switch. The reed switch will cause the dry reed switch to close and open, and then accumulate the rainfall by the number of times the dry reed switch is connected, so as to realize the detection of rainfall; the connecting mechanism includes a fixed block 2, which is fixedly connected to the surface of the base 1, and the surface of the fixed block 2 is provided with a connecting groove 21 and a connecting hole 22. The surface of the rain receiver 11 is fixedly connected to a connecting bin 23, and the inner surface of the connecting bin 23 is movably connected to a supporting spring 24 and a limiting plate 25. The surface of the limiting plate 25 is fixedly connected to a clamping block 26, and the surface of the connecting bin 23 is provided with a through hole 27. The fixed block 2 and the connecting bin 23 are respectively arranged in a circular array on the surface of the base 1 and the rain receiver 11.

[0026] Four groups of fixing blocks 2 and connecting chambers 23 are provided. The four groups of fixing blocks 2 are installed at the four ends of the base 1, and the four groups of connecting chambers 23 are installed at the four ends of the rain receiver 11. The connecting chambers 23 are connected to the surface of the fixing block 2 through the connecting groove 21. The outer diameter of the connecting chamber 23 is the same as the outer diameter of the connecting groove 21. The connecting groove 21 is an arc-shaped groove. The base 1 and the rain receiver 11 can be connected through the connection between the fixing block 2 and the connecting chamber 23. One side of the support spring 24 is connected to the inner surface of the connecting chamber 23, and the other side of the support spring 24 is connected to the surface of the limit plate 25. The limit plate 25 is slidably connected to the inner surface of the connecting chamber 23. The support spring 24 can apply a supporting force on the surface of the limit plate 25, so that the limit plate 25 and the block 26 always have a tendency to move toward the outside of the connecting chamber 23. Under the action of the limit plate 25, the block 26 can be installed and the block 26 can be limited, thereby preventing the block 26 from flying out of the fixed block 2 due to the support spring 24. The clamping block 26 is movably connected to the surface of the through hole 27, one side of the clamping block 26 is fixedly connected to the surface of the limiting plate 25, and the other side of the clamping block 26 is clamped and connected to the surface of the connecting hole 22.

Under the connection between the clamping block 26, the through hole 27 and the connecting hole 22, the limiting effect of the connected fixed block 2 and the connecting chamber 23 can be achieved, thereby limiting the connection between the base 1 and the rain receiver 11.

[0027] The surface of the filter plate 16 is provided with a quick-release mechanism, which includes a side plate 3, which is fixedly connected to the surface of the filter plate 16, and a snap-fitting hole 31 is provided on the surface of the side plate 3. The surface of the rain receiver 11 is fixedly connected to a mounting block 32, and the surface of the rain receiver 11 is movably connected to a snap-fitting plate 33. A groove 34 is provided on the surface of the mounting block 32, and a rotating block 35 is fixedly connected to the surface of the snap-fitting plate 33. A torsion spring 36 is installed on the surface of the rotating block 35. The inner surface of the side plate 3 is abutted against the rain receiver 11, and one side of the side plate 3 is connected to the filter plate 16, while the other side is connected to the snap-fitting plate 33 through the snap-fitting hole 31. There are two groups of side panels 3, which are installed on both sides of the filter plate 16. The surface of the engaging hole 31 is rectangular. There are two groups of mounting blocks 32, which are installed on both sides of the engaging plate 33. The engaging plate 33 is engaged and connected to the surface of the engaging hole 31. The mounting block 32 can achieve the installation effect of the engaging plate 33, and under the connection between the engaging plate 33 and the engaging hole 31, the side panel 3 can be limited, thereby limiting the filter plate 16 installed in the rain receiver 11. The cross-section of the engaging plate 33 is "L"-shaped.

[0028] Two groups of rotating blocks 35 are provided, and the two groups of rotating blocks 35 are installed on both sides of the engaging plate 33. The rotating blocks 35 are rotatably connected to the surface of the groove 34. One end of the torsion spring 36 is abutted and connected to the surface of the mounting block 32, and the other end of the torsion spring 36 is abutted and connected to the surface of the engaging plate 33. Under the connection between the groove 34 and the rotating block 35, the engaging plate 33 can be rotated with the rotating block 35 as the center, and under the action of the torsion spring 36, a torsional force can be applied to the engaging plate 33 and it always has a tendency to rotate toward the side of the rain receiver 11.

[0029] Working principle: When connecting the base 1 and the rain receiver 11, first put the base 1 on the outside of the bracket 13 and press it against the surface of the base 1, then rotate the rain receiver 11 so that the connecting chamber 23 slides on the surface of the connecting groove 21. At this time, the block 26 is squeezed and moves toward the inside of the connecting chamber 23, and drives the limit plate 25 to slide on the inner surface of the connecting chamber 23, and the support spring 24 is in a compressed state. When the through hole 27 and the connection hole 22 are aligned, the limit plate 25 and the block 26 move again under the action of the supporting force exerted by the support spring 24, so that the limit plate 25 presses against the inside of the connecting chamber 23 again, and the block 26 passes through the through hole 27 and engages with the surface of the connection hole 22, thereby connecting and installing the base 1 and the rain receiver 11.

[0030] When cleaning or replacing the filter plate 16, first bend the two sets of snap plates 33 toward the two sides of the rain receiver 11 so that they rotate around their respective rotating blocks 35. The rotating blocks 35 rotate on the surface of the grooves 34 and cancel the snap plates 33 from the snap holes 31. At this time, the torsion springs 36 twist and generate a torsional force on the snap plates 33. The operator then removes the filter plate 16 from the base 1 and replaces it by lifting the side plates 3 on both sides, taking out the filtered impurities.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
