Description

Technical Field

[0001] The invention relates to the field of meteorological measuring equipment, in particular to a tipping bucket and a rain gauge. Background Art

[0002] Rain gauge is a meteorological and hydrological instrument used to measure the amount of precipitation in the atmosphere at a certain time interval, and convert the precipitation into digital information output in the form of switch quantity to meet the needs of information transmission, processing, recording and display. It is suitable for meteorological stations, hydrological stations, agriculture and forestry, national defense, field observation stations and other departments, and can provide original data for meteorological support, flood control, water supply scheduling, and water management of power stations and reservoirs.

[0003] The rain gauge comprises a water receiving box and a tipping bucket. Adjustment bolts are screwed on both sides of the existing tipping bucket. The tipping bucket is adjusted by rotating the two adjustment bolts. This structure is complicated to adjust and time-consuming. Summary of the invention

[0004] In view of the above problems, the present invention provides a tipping bucket and a rain gauge.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A tipping bucket comprises a middle part and water receiving parts arranged on both sides of the middle part, a ceramic blade is installed at the lower end of the middle part, a balance bar is provided at one end of the middle part, and the length direction of the balance bar is perpendicular to the length direction of the ceramic blade, and the middle part, the water receiving part and the balance bar are an integrally formed part.

[0007] The tipping bucket contains a balance bar, which replaces the left and right screws of the traditional tipping bucket that are manually adjusted, greatly reducing the debugging time. In addition, the middle part, the water receiving part and the balance bar are integrated into a single piece, and the left and right sides are more balanced, which can ensure the consistency of the tipping bucket batch and the consistency of the detection accuracy; the ceramic blade is used to cooperate with the water receiving box of the rain gauge, which has low friction, smaller turning resistance, and can achieve the effect of never rusting.

[0008] In one embodiment of the present invention, the lower end of the middle portion has a fixing groove, and the ceramic blade is embedded in the fixing groove.

[0009] The ceramic blade can be fixed to the fixing groove by interference fit, fasteners or glue, and can also be directly molded on the ceramic blade by a mold when processing the middle part, the water receiving part and the balance rod. Preferably, the ceramic blade is processed into one piece when the middle part, the water receiving part and the balance rod are injection molded.

[0010] In one embodiment of the present invention, an end of the middle portion away from the balance bar has a magnetic member.

[0011] In actual use, the magnetic parts can be directly embedded when processing the middle part, the water receiving part and the balance rod, or installed later.

[0012] In one embodiment of the present invention, the middle portion is a plate-like structure, and both sides of the upper end of the middle portion have inclined cut surfaces, and the two cut surfaces intersect with each other to form a cutting edge; the upper end of the middle portion is a concave structure.

[0013] The design of the cutting surface and the cutting edge enables the water column to be cut quickly when the bucket is flipped, thus reducing the error during flipping.

[0014] In one embodiment of the present invention, the end of the water receiving portion has a drain port.

[0015] The end of the water receiving portion is the end of the water receiving portion away from the middle portion. By arranging a drain port at the end of the water receiving portion, the surface tension of the water can be broken to achieve rapid drainage.

[0016] In one embodiment of the present invention, the lower surface of the end of the water receiving portion is V-shaped; the upper surface of the end of the water receiving portion is V-shaped, and the bottom is transitioned through an arc surface.

[0017] The lower surface of the end of the water receiving part is V-shaped, which can reduce the wind-receiving surface when flipping, thereby reducing wind resistance and improving detection accuracy. The upper surface of the end of the water receiving part is V-shaped, and the bottom is transitioned through an arc surface. This arrangement can prevent rainwater from forming tension with both sides, because if it is at a right angle, rainwater will form tension with both sides, resulting in a large amount of rainwater remaining.

[0018] In one embodiment of the present invention, the upper surface of the water receiving portion is in an arc-shaped area near the middle portion, and the upper surface of the water receiving portion gradually changes from the arc-shaped surface to the end portion into a V-shaped surface.

[0019] The upper surface of the water receiving part near the middle part is an arc-shaped surface, and this structure can increase the capacity of the water receiving part; the upper surface of the water receiving part gradually changes from an arc-shaped surface to a V-shaped surface toward the end, and this change can achieve rapid diversion and drainage and reduce rainwater residue.

[0020] In one embodiment of the present invention, the further away the water receiving portion is from the middle portion, the smaller the width of the water receiving portion is; when the bucket is in a horizontal state, the position of the lowest point on the upper surface of the water receiving portion gradually changes, and the further away from the middle portion, the lower the position is.

[0021] The further away the water receiving part is from the middle part, the smaller the width of the water receiving part. This structure makes the water receiving part smaller in size the further away from the middle part, and the further away the water receiving part is from the middle part, the greater its flipping speed. Therefore, by reducing the distance of the water receiving part from the middle part, the resistance can be reduced, the flipping time can be shortened, and the detection accuracy can be higher. The position of the lowest point on the upper surface of the water receiving part gradually changes, and the position is lower the farther away from the middle part. This sloped design can promote rainwater to gather to the end of the water receiving part after the tipping bucket is flipped, thereby increasing drainage efficiency.

[0022] In one embodiment of the present invention, the upper surface of the water receiving portion is a frosted surface.

[0023] The frosted surface can quickly form a water film after being moistened, ensuring that the amount of rainwater remaining on the upper surface of the water receiving part is basically the same after each turning, and the formation of a water film can also promote the flow of rainwater.

[0024] The present application also discloses a rain gauge, comprising the tipping bucket described above.

[0025] The beneficial effects of the present invention are as follows: the tipping bucket contains a balance bar, which replaces the left and right screws of the traditional tipping bucket that are manually adjusted, greatly reducing the debugging time consumption. Moreover, the middle part, the water receiving part and the balance bar are integrated into a single-piece processing, and the left and right sides are more balanced, which can ensure the consistency of the tipping bucket batch and the consistency of the detection accuracy; the ceramic blade is used to cooperate with the water receiving box of the rain gauge, which has low friction and smaller turning resistance, and can achieve the effect of never rusting.

[0046] The present invention is described in detail below in conjunction with the accompanying drawings.

[0047] like Figure 1 and 2 As shown, this embodiment discloses a rain gauge, which includes a bird spike 1, a filter 2, an outer tube 3, an inner funnel 4, a Z-shaped bracket 5, an adjusting bolt 6, a tipping bucket 7, a water receiving box 8, a supporting frame 9, a wind shield 10, an adjusting member 11 and a chassis 12.

[0048] like Figure 2 and 3 As shown, the outer cylinder 3 of this embodiment includes an outer cylinder body 13, and the outer side wall of the outer cylinder body 13 includes a first part 14 and a second part 15 connected to each other, the first part 14 is located above the second part 15, and the first part 14 and the second part 15 are both conical, and the small diameter end (not marked in the figure) of the first part 14 is connected to the small diameter end (not marked in the figure) of the second part 15.

[0049] like Figure 2 and 3As shown, the small diameter end of the first part 14 is connected to the small diameter end of the second part 15 to form a small waist shape, so that when the wind blows, negative pressure is formed on both sides of the outside to absorb raindrops, which can effectively reduce the impact of wind on rainfall detection. The outer tube 3 of the present application has a simple structure and eliminates the traditional windproof skirt.

[0050] In this embodiment, the large diameter end (not shown in the figure) of the first part 14 is a water inlet, and the water inlet has an arc-shaped inwardly contracted annular portion 16. The annular portion 16 can reduce the rainwater splashing into the outer cylinder body 13, and can ensure the accuracy of measurement. In actual use, the end cut of the annular portion 16 is less than 45°.

[0051] In this embodiment, the outer cylinder body 13 is integrally formed by spinning. The existing outer cylinder 3 is a metal structure formed by welding. Due to the presence of the weld, the inner wall of the outer cylinder 3 has serious residual water droplets, which will affect the measurement accuracy. The outer cylinder body of the present application is integrally formed by spinning, replacing traditional welding and splicing, reducing the seams, so that the inner wall of the outer cylinder body remains smooth and integrated, effectively reducing the problem of rainwater residue inside the traditional metal outer cylinder, and can effectively improve the accuracy of detection.

[0052] The inner wall of the outer cylinder body is sprayed with plastic to make the inner surface of the outer cylinder body smoother and reduce rainwater residue.

[0053] like Figure 1 , 2 As shown in FIG. 5 , in this embodiment, the bird spike 1 is installed at the upper opening of the outer cylinder body 13, and the bird spike 1 includes:

[0054] A mounting sleeve 17, which is mounted on the outer wall of the upper end of the outer cylinder body 13, and has a plurality of first needles 18 extending upward;

[0055] The first locking screw 19 is threadedly connected to the installation sleeve 17 , and the end portion thereof is used to cooperate with the outer cylinder body 13 so that the installation sleeve 17 and the outer cylinder body 13 are relatively fixed.

[0056] The mounting sleeve 17 is fixed to the outer cylinder body 13 by the first locking screw 19. The first needle 18 on the mounting sleeve 17 can prevent birds from staying on it, that is, prevent birds from staying at the opening end of the outer cylinder body 13 to affect the measurement accuracy. In actual use, the first needle 18 can be a steel needle.

[0057] like Figure 2 and 5As shown, in this embodiment, the upper end of the mounting sleeve 17 has an anti-slip ring 20, and the minimum inner diameter of the anti-slip ring 20 is smaller than the maximum outer diameter of the annular portion 16. The mounting sleeve 17 has the anti-slip ring 20, and the minimum inner diameter of the anti-slip ring 20 is smaller than the maximum outer diameter of the annular portion 16. Therefore, through the cooperation of the anti-slip ring 20 and the annular portion 16, the mounting sleeve 17 can be quickly covered on the outer cylinder body 13 (without falling off), and then fixed by the first locking screw 19.

[0058] like Figure 2 and 4 As shown, the filter element 2 of this embodiment includes:

[0059] A support portion 21, wherein the outer wall of the support portion 21 is evenly provided with a plurality of support bars 22 extending horizontally outward around the circumference, and each support bar 22 is used to contact the inner wall of the outer cylinder body 13;

[0060] The filter screen 23 is mounted on the support portion 21 , and the outermost side of the filter screen 23 is gap-matched with the inner side wall of the outer cylinder body 13 .

[0061] The support strip 22 contacts the inner wall of the outer cylinder body 13 so that the support portion 21 is limited on the outer cylinder body 13, and the filter screen 23 can filter debris such as leaves. The outermost side of the filter screen 23 is in clearance with the inner wall of the outer cylinder body 13. This structure can reduce the loss of rainwater on the inner wall of the outer cylinder body 13. This structure and matching method of the filter element 2 are convenient and quick to replace and clean.

[0062] like Figure 4 As shown, in this embodiment, the inner side wall corresponding to the outer cylinder body 13 and the first part 14 is a conical inner side wall (not marked in the figure), and the end of the support bar 22 has an inclined surface 24, and the inclined surface 24 is used to abut against the conical inner side wall. The inclined surface 24 abuts against the conical inner side wall, and this form of cooperation is reliable and convenient for the installation and positioning of the filter element 2.

[0063] like Figure 4 As shown, in this embodiment, a second needle 25 is installed on the upper end of the support portion 21. The second needle 25 can prevent birds from staying on the filter element 2 to make nests. In actual use, the second needle 25 can be a steel needle.

[0064] like Figure 4 As shown, in this embodiment, it also includes an inner funnel 4 for receiving water from the inner side wall of the outer cylinder body 13, and a third needle 26 is installed at the lower end of the support portion 21. The third needle 26 is used to extend to the water inlet (not shown) inside the outer cylinder body 13, corresponding to the inner funnel 4. The third needle 26 can ensure that the filter element 2 is stable and will not fall due to external force, and also has a diversion function, so that rainwater can enter the inner funnel 4 vertically and quickly.

[0065] In this embodiment, the second needle 25 and the third needle 26 are an integrated part.

[0066] The rain gauge of this embodiment includes a chassis and an outer cylinder connection structure, such as Figure 1 , 2 As shown in Figure 6, the chassis and outer cylinder connection structure includes:

[0067] The chassis 12 has a convex ring 27 on its upper end surface, and the chassis 12 is provided with a plurality of through holes 28 along the circumferential direction, and the through holes 28 are located outside the convex ring 27;

[0068] The outer cylinder 3 has a plurality of threaded holes (not shown) on its lower end surface, and a positioning side wall (not shown) on its lower end. The lower end surface of the outer cylinder 3 contacts the upper end surface of the chassis 12, and the convex ring 27 is embedded in the positioning side wall. The threaded holes correspond to the through holes 28 one by one.

[0069] A fixing bolt (not shown) is used to pass through the through hole 28 from the lower end of the chassis 12 and be fixed to the corresponding threaded hole.

[0070] Through the cooperation of the convex ring 27 and the positioning side wall, the force-bearing area can be increased, so that the connection between the chassis 12 and the outer tube 3 is reliable and the structural strength is good; the fixing bolts pass through the through holes 28 from the lower end of the chassis 12 and are fixed to the corresponding threaded holes. This structure eliminates the need to punch holes in the outer wall of the outer tube 3, and the fixing bolts can be hidden. It is not only simple and beautiful, but also not easy for the fixing bolts to enter water and are not easily corroded.

[0071] In actual use, the chassis 12 can be an integrally processed aluminum alloy chassis 12 with a hollowed-out structure inside, which can ensure both very high strength and light overall weight.

[0072] like Figure 2 and 6 As shown, in this embodiment, the convex ring 27 has a recessed portion 29, and the positioning side wall has a protrusion (not shown in the figure) that cooperates with the recessed portion 29. Through the cooperation between the recessed portion 29 and the protrusion, the outer cylinder 3 and the chassis 12 are positioned in the circumferential direction.

[0073] like Figure 2 , 3 As shown in FIG. 6 , in this embodiment, the chassis 12 has a first positioning mark 30, and the lower end of the outer tube 3 has a second positioning mark 31. When the first positioning mark 30 and the second positioning mark 31 are aligned, the recessed portion 29 matches the raised portion. By providing the first positioning mark 30 and the second positioning mark 31, the recessed portion 29 can be quickly matched with the raised portion, so that the through hole 28 and the threaded hole are aligned, thereby achieving rapid installation.

[0074] like Figure 1 , 2, 6 and 14, in this embodiment, the lower part of the chassis 12 has a hollow connecting portion 32, and a plurality of second locking screws 33 are threadedly connected to the connecting portion 32. The connecting portion 32 is used for inserting the connecting pipe 34, and the second locking screws 33 are used to cooperate with the connecting pipe 34 to relatively fix the connecting portion 32 and the connecting pipe 34. The design of the connecting portion 32 and the second locking screws 33 enables the connecting portion 32 to cooperate with connecting pipes 34 of various outer diameters, and has strong adaptability; the outer jacket and the chassis 12 can be raised through the connecting pipe 34, which is more convenient and accurate for measurement.

[0075] In this embodiment, there are multiple second locking screws 33 , which are evenly distributed around the axis of the connecting portion 32 .

[0076] The rain gauge of this embodiment includes an inner funnel installation structure, such as Figure 2 , 6 , 7 and 8, the inner funnel installation structure includes:

[0077] Chassis 12;

[0078] The Z-shaped bracket 5 includes a first horizontal portion 35, a vertical portion 36 and a second horizontal portion 37 which are connected in sequence, wherein the second horizontal portion 37 is located above the first horizontal portion 35, and has a positioning hole 38 on the second horizontal portion 37, and the first horizontal portion 35 is fixed on the chassis 12;

[0079] The inner funnel 4 has a water storage section 39 and a water outlet section 40, and the water outlet section 40 extends into the positioning hole 38;

[0080] The adjusting bolt 6 is screwed on the second horizontal portion 37 , and the end of the adjusting bolt 6 is used to extend into the positioning hole 38 and cooperate with the water outlet section 40 to lock the inner funnel 4 .

[0081] The Z-shaped bracket 5 is fixed on the chassis 12 through the first horizontal portion 35, and the second horizontal portion 37 is raised through the vertical portion 36. The inner funnel 4 is installed through the adjusting bolt 6 and the positioning hole 38 of the second horizontal portion 37. This structure is relatively simple and has reliable connection. In actual use, after the position of the inner funnel 4 is adjusted, the inner funnel 4 is locked by rotating the adjusting bolt 6, so that the rainwater from the water outlet section 40 of the inner funnel 4 can finally fall into the middle position of the tipping bucket 7.

[0082] In actual use, the first horizontal portion 35 can be fixed on the chassis 12 by fasteners.

[0083] like Figure 7 and 8As shown, in this embodiment, there is a tapered section 41 between the water storage section 39 and the water outlet section 40, the upper end of the positioning hole 38 has a chamfer 42, and the outer side wall of the tapered section 41 and the chamfer 42 are in close contact with each other. The tapered section 41 and the chamfer 42 are in close contact with each other, and this structure facilitates the positioning of the inner funnel 4 and has better force.

[0084] like Figure 7 As shown, in this embodiment, the water outlet section 40 is provided with a slit 43 along its own axial direction, and the slit 43 extends to the lowermost end of the water outlet section 40. The slit 43 can break the tension of water, so that rainwater can quickly flow into the tipping bucket 7, and the water column formed by the water flow after the slit 43 is opened will be longer and straighter, which can reduce the water flow error when the tipping bucket 7 is turned over.

[0085] In this embodiment, the gap of the slit 43 is 0.4 mm to 0.6 mm.

[0086] like Figure 2 and 6 As shown, in this embodiment, a level bubble 44 is installed on the upper end surface of the chassis 12. The level bubble 44 is used to indicate the level. If it is not level, it will affect the measurement and make the measurement result inaccurate.

[0087] like Figure 2 , 6 As shown in FIG. 8 , in this embodiment, a circuit board 45 is mounted on the vertical portion 36 , and a reed switch (not shown in the figure) is mounted on the circuit board 45 .

[0088] like Figure 8 , 13 , 14 and 15, the water receiving box 8 of this embodiment includes a box body 46, the bottom wall of the box body 46 includes two left and right inclined flow guide surfaces 47, the higher ends of the two inclined flow guide surfaces 47 are connected to each other, and the bottom wall of the box body 46 also has two drainage ports 48, which are respectively arranged on the two inclined flow guide surfaces 47, and the drainage ports 48 are located at the lowest position of the corresponding inclined flow guide surfaces 47. The design of the two drainage ports 48 can discharge the rainwater flowing into the box body 46 nearby, and the drainage ports 48 are located at the lowest position of the corresponding inclined flow guide surfaces 47. This structure allows the rainwater discharged from the tipping bucket 7 to flow quickly to the drainage ports 48, which can quickly drain the residual water droplets, keep the barrel dry, and improve the service life of the product.

[0089] like Fig.13 and 15 As shown, in this embodiment, a plurality of reinforcing ribs 49 are provided on the outer side wall of the box body 46. The reinforcing ribs 49 can ensure that the box body 46 has a very high strength and is not easily deformed, so that the dump bucket 7 can be kept horizontally placed.

[0090] like Figure 8As shown, in this embodiment, there is a connecting plate 50 between the reinforcing ribs 49, and the connecting plate 50 is used to be fixed to the chassis 12 of the rain gauge. In actual use, the connecting plate 50 can be fixed to the chassis 12 by fasteners.

[0091] like Figure 2 , 8 , 13 and 16, in this embodiment, two support frames 9 are provided on the box body 46, and the support frames 9 have V-shaped grooves 51, and the support frames 9 support the two ends of the tipping bucket 7 of the rain gauge through the two V-shaped grooves 51. The box body 46 is provided with two support frames 9, which also includes the case where the contract and the support frames 9 are an integrated part.

[0092] like Fig.13 and 15 As shown, in this embodiment, the box body 46 has a mounting groove 52, and the support frame 9 is embedded in the mounting groove 52. Through the separate design of the support frame 9 and the mounting groove 52, when the support frame 9 is worn out, only the support frame 9 needs to be replaced, and the entire box body 46 does not need to be replaced, which can reduce waste.

[0093] like Fig.13 and 15 As shown, in this embodiment, the intersection of the two inclined guide surfaces 47 is an intersection line 53 , and the two support frames 9 are symmetrically arranged on both sides of the intersection line 53 .

[0094] In this embodiment, the support frame 9 is made of sintered steel, which is wear-resistant and wear-resistant and has a long service life.

[0095] The rain gauge of this embodiment includes a water receiving box windproof structure, such as Figure 2 , 8 As shown in Figures 13, 14 and 17, the water receiving box windproof structure includes a water receiving box 8 and a wind shield 10. The water receiving box 8 includes a box body 46. The bottom wall of the box body 46 is provided with a drain port 48. The wind shield 10 is arranged at the drain port 48. The side wall of the wind shield 10 is provided with a through port 54. The water in the box body 46 flows into the drain port 48 through the through port 54.

[0096] The wind shield 10 is provided, firstly, to reduce the wind speed entering the box body 46, and secondly, to change the wind direction so that the wind does not directly enter the box body 46 along the direction of the drain port 48, but enters the box body 46 through the through port 54 on the side wall of the wind shield 10. This can change the wind direction and divert the wind to the surroundings, thereby reducing the impact of the wind on the tipping bucket 7.

[0097] like Fig.17 As shown, in this embodiment, the wind shield 10 includes:

[0098] The wind shield 55 is located above the drain outlet 48 and directly faces the drain outlet 48;

[0099] A hollow mounting portion 56, located below the wind shield portion 55, is used to mount the wind shield 10 on the box body 46;

[0100] The connecting strip 57 is used to connect the wind shielding portion 55 and the mounting portion 56 .

[0101] like Fig.17 As shown, in this embodiment, there are a plurality of connecting strips 57 , and the space between two adjacent connecting strips 57 is a through opening 54 .

[0102] like Fig.14 As shown, in this embodiment, the upper portion of the drain port 48 has a slot 58, and the mounting portion 56 is engaged with the slot 58. The mounting portion 56 is engaged with the slot 58, and this structure is easy to install.

[0103] In this embodiment, the wind shield 10 is an integrally formed part, and the wind shield 10 is a plastic part. The plastic part has a certain amount of deformation, which facilitates the rapid installation of the wind shield 10.

[0104] In other embodiments, the mounting portion 56 may also be threadedly matched with the drain port 48. The mounting portion 56 is threadedly matched with the drain port 48, and this matching structure is reliable in fixation.

[0105] like Fig.17 As shown, in this embodiment, the upper surface of the wind shield 55 has a water guiding slope 59. The upper surface of the wind shield 55 has a water guiding slope 59, and this structure can prevent excessive rainwater from remaining in the wind shield 55.

[0106] The rain gauge of this embodiment includes a tipping bucket adjustment structure, such as Figure 2 , 8 , 9, 13, 14 and 18, the bucket adjustment structure includes:

[0107] The water receiving box 8 comprises a box body 46;

[0108] The tipping bucket 7 is movably mounted on the water receiving box 8 and can be turned left and right relative to the water receiving box 8. The tipping bucket 7 includes a middle portion 61 and water receiving portions 60 arranged on both sides of the middle portion 61;

[0109] Two adjusting members 11 are respectively arranged below the ends of the corresponding water receiving parts 60. The adjusting members 11 include a screw rod 70 and a limit platform 71 located at the upper end of the screw rod 70. The screw rod 70 is threadedly matched with the bottom wall of the box body 46. The height of the limit platform 71 can be adjusted by rotating the adjusting member 11. The limit platform 71 is used to contact the water receiving part 60 when the water receiving part 60 is flipped downward to limit the rotation angle of the water receiving part 60. The limit platform 71 is provided with a water-draining groove 72, and at least one end of the water-draining groove 72 extends to the edge of the limit platform 71.

[0110] By rotating the adjusting piece 11, the height of the limit platform 71 can be adjusted, and then the turning angle of the tipping bucket 7 can be limited, that is, the detection amount of the single bucket of the tipping bucket 7 can be adjusted. This adjustment method is simple, reliable and very convenient. After adjustment, the consistency of the weight of the tipping bucket 7 each time can be improved, and the stability of the tipping bucket 7 can be increased; at least one end of the drain groove 72 extends to the edge of the limit platform 71. This structure enables the drain groove 72 to break the tension of the water surface, thereby realizing rapid drainage, and can quickly guide the rainwater in the water receiving part 60 to be emptied, with a good diversion effect.

[0111] The adjusting member 11 of the present application has a simple structure and integrates multiple functions. A traditional rain gauge needs the cooperation of multiple parts to realize these functions.

[0112] like Fig.18 As shown, in this embodiment, both ends of the drain groove 72 extend to the edge of the limiting platform 71. Both ends of the drain groove 72 extend to the edge of the limiting platform 71, which can better drain water.

[0113] In this embodiment, the drain groove 72 is a straight-line structure; there are two drain grooves 72, forming a cross-shaped structure. The cross-shaped structure not only ensures a good drain effect, but also the four parts formed by the two drain grooves 72 can make the height adjustment more refined, that is, the rotation angle can be determined, and the rotation adjustment can be 90°, 90°, so that the tipping bucket 7 can be accurately adjusted to the ideal tipping position.

[0114] like Fig.18 As shown, in this embodiment, both ends of the drain groove 72 penetrate the limiting platform 71. Both ends of the drain groove 72 penetrate the limiting platform 71. This structure can achieve a better drainage effect.

[0115] like Figure 8 and 14 As shown, in this embodiment, the wind shield 10 is located below the water receiving portion 60 and away from the water receiving portion 60. The wind shield 10 is located below the water receiving portion 60 and away from the water receiving portion 60, so that the influence of wind on the tipping bucket 7 can be minimized.

[0116] The rain gauge of this embodiment includes a mounting structure of a tipping bucket and a water receiving box, such as Figure 2 , 8 , 9, 13, 15 and 16, the installation structure of the tipping bucket and the water receiving box includes:

[0117] The water receiving box 8 includes a box body 46, on which two support frames 9 are arranged, and the support frames 9 have V-shaped grooves 51;

[0118] The tipping bucket 7 includes a middle portion 61 and water receiving portions 60 arranged on both sides of the middle portion 61. A ceramic blade 62 is installed at the lower end of the middle portion 61. The two ends of the ceramic blade 62 respectively cooperate with the corresponding V-shaped groove 51. The tipping bucket 7 can be flipped left and right relative to the water receiving box 8 through the ceramic blade 62.

[0119] The ceramic blade 62 cooperates with the V-shaped groove 51, and compared with the traditional axle-type dump bucket 7, the dumping resistance is small, so a more accurate detection result can be obtained, and the ceramic blade 62 will never rust, which can effectively increase the service life in areas such as the seaside.

[0120] Two support frames 9 are arranged on the box body 46, which also includes the case where the contract and the support frames 9 are an integrated part.

[0121] like Figure 8 and 9 As shown, in this embodiment, the blade 73 of the ceramic blade 62 cooperates with the V-shaped groove 51. The contact area between the blade 73 and the V-shaped groove 51 is small, and the flipping is more sensitive.

[0122] like Fig. 9 As shown, in this embodiment, the two ends of the ceramic blade 62 are inclined to form an acute angle structure. The two ends of the ceramic blade 62 are inclined to form an acute angle structure. This arrangement can reduce the contact surface between the blade and the water receiving box 8, reduce friction, and improve sensitivity.

[0123] In this embodiment, the intersection of the two inclined guide surfaces 47 is an intersection line 53 , and the two support frames 9 are symmetrically arranged on both sides of the intersection line 53 .

[0124] like Fig. 9 As shown, the dump bucket 7 of this embodiment includes a middle portion 61 and water receiving portions 60 arranged on both sides of the middle portion 61 .

[0125] like Figure 8 and 9 As shown, the end of the water receiving portion 60 has a drain port 67. The end of the water receiving portion 60 is the end of the water receiving portion 60 away from the middle portion 61. By providing the drain port 67 at the end of the water receiving portion 60, the surface tension of the water can be broken to achieve rapid drainage.

[0126] like Figure 8 and 9As shown, a ceramic blade 62 is installed at the lower end of the middle part 61, and a balance rod 63 is provided at one end of the middle part 61. The length direction of the balance rod 63 is perpendicular to the length direction of the ceramic blade 62. The middle part 61, the water receiving part 60 and the balance rod 63 are an integrally formed part. The tipping bucket 7 contains a balance rod 63, which replaces the left and right screws of the traditional tipping bucket 7 that are manually adjusted, greatly reducing the debugging time consumption. Moreover, the middle part 61, the water receiving part 60 and the balance rod 63 are integrated and formed, and the left and right sides are more balanced, which can ensure the consistency of the batch of the tipping bucket 7 and the consistency of the detection accuracy; the ceramic blade 62 is used to cooperate with the water receiving box 8 of the rain gauge, with small friction and smaller turning resistance, and can achieve the effect of never rusting.

[0127] like Fig. 9 As shown, in this embodiment, the lower end of the middle part 61 has a fixing groove 64, and the ceramic blade 62 is embedded in the fixing groove 64. The ceramic blade 62 can be fixed to the fixing groove 64 by interference fit, fasteners or glue, and can also be directly molded on the ceramic blade 62 by a mold when processing the middle part 61, the water receiving part 60 and the balance bar 63. Preferably, the ceramic blade is processed into one piece when the middle part, the water receiving part and the balance bar are injection molded.

[0128] In this embodiment, the middle portion 61 has a magnetic member (not shown) at one end away from the balance bar 63. In actual use, the magnetic member can be directly embedded when processing the middle portion 61, the water receiving portion 60 and the balance bar 63, or installed later.

[0129] The magnetic part is used to cooperate with the reed switch. The second horizontal part 37 is above the water receiving box 8, and the water in the inner funnel 4 flows into the water receiving part 60 of the tipping bucket 7, so that the tipping bucket 7 can be turned left and right. When turning over, the magnetic part can approach and move away from the reed switch. When the magnetic part approaches the reed switch, a turning signal can be obtained. This structure is simple and the measurement is more reliable.

[0130] like Fig. 9 As shown, in this embodiment, the middle part 61 is a plate-like structure, and the upper end of the middle part 61 has inclined cut surfaces 65 on both sides, and the two cut surfaces 65 intersect each other to form a cutting edge 66; the upper end of the middle part 61 is a concave structure. The design of the cut surface 65 and the cutting edge 66 enables the water column to be quickly cut when the tipping bucket 7 is turned over, thereby reducing the error during the turning.

[0131] like Figure 8 , 9 As shown in FIG. 12 , in this embodiment, the lower surface of the end of the water receiving portion 60 is V-shaped. The lower surface of the end of the water receiving portion 60 is V-shaped, which can reduce the wind-receiving surface during flipping, thereby reducing wind resistance and improving detection accuracy.

[0132] like Figure 8 , 9As shown in Figure 12, in this embodiment, the upper surface of the end of the water receiving portion 60 is V-shaped, and the bottom is transitioned by an arc surface 68. This arrangement can prevent rainwater from forming tension with both sides, because if at right angles, rainwater forms tension with both sides, resulting in a large amount of rainwater remaining.

[0133] like Fig. 9 and 11 As shown, in this embodiment, the upper surface of the water receiving portion 60 near the middle portion 61 is an arcuate surface 69, and the upper surface of the water receiving portion 60 gradually changes from the arcuate surface 69 to the end portion to a V-shaped surface. The upper surface of the water receiving portion 60 near the middle portion 61 is an arcuate surface 69, and this structure can increase the capacity of the water receiving portion 60; the upper surface of the water receiving portion 60 gradually changes from the arcuate surface 69 to the end portion to a V-shaped surface, and this change can achieve rapid diversion and drainage, and reduce rainwater residue.

[0134] like Fig. 9 As shown, in this embodiment, the further the water receiving portion 60 is from the middle portion 61, the smaller the width of the water receiving portion 60 is. This structure makes the water receiving portion 60 smaller the further away from the middle portion 61, and the water receiving portion 60 is further away from the middle portion 61, the faster it turns over. Therefore, by reducing the distance of the water receiving portion 60 from the middle portion 61, the resistance can be reduced, the turning time can be shortened, and the detection accuracy can be higher.

[0135] In this embodiment, the upper surface of the water receiving portion 60 is a frosted surface. The frosted surface can quickly form a water film after being wetted, ensuring that the amount of rainwater remaining on the upper surface of the water receiving portion 60 is substantially the same after each flipping, and the formation of a water film can also promote the flow of rainwater.

[0136] like Fig.10 As shown, in this embodiment, when the bucket 7 is in a horizontal state, the position of the lowest point on the upper surface of the water receiving portion 60 gradually changes, and the position becomes lower as it is farther away from the middle portion 61. This sloped design can promote rainwater to gather at the end of the water receiving portion 60 after the bucket 7 is turned over, thereby increasing drainage efficiency.

[0137] In the rain gauge of this embodiment, the lower end of the outer tube 3 is fixed to the chassis 12 to form an installation space (not marked in the figure). Specifically, the second part 15 and the chassis 12 form an installation space, and the Z-shaped bracket 5, the inner funnel 4, the water receiving box 8, the tipping bucket 7, the waterproof cover, and the adjustment member 11 are all located in the installation space.

[0138] In the present application, the water in the water receiving box 8 is discharged through the drain port 48 , and the hidden danger is disclosed that there is a through hole on the chassis 12 corresponding to the drain port 48 , and the rainwater is discharged from the drain port 48 through the through hole.

[0139] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention and the drawings, directly or indirectly used in other related technical fields, is also included in the protection scope of the present invention.
