Abstract
Description
Technical Field
[0001] This utility model relates to the field of precipitation sampling technology, and more specifically, to a meteorological monitoring precipitation sampling device. Background Technology
[0002] Meteorological monitoring precipitation sampling devices, commonly known as automatic precipitation samplers or automatic rainfall samplers, are specialized meteorological monitoring equipment. These devices monitor precipitation, providing researchers with abundant precipitation data. This data is crucial for studying climate change trends, assessing environmental quality, and developing strategies to address climate change. Precipitation sampling devices are not only used in meteorological monitoring but also widely applied in environmental monitoring, hydrological research, agricultural guidance, and many other fields.
[0003] In the prior art, document CN222028007U discloses a meteorological monitoring precipitation sampling device. This device uses a hot air blower installed inside to heat the water collection hopper, thereby heating the solid precipitation and preventing blockages that could hinder rainwater collection. However, under harsh conditions, especially when encountering hail-like solid precipitation, large hailstones fall into the collection hopper. Because the hailstones accumulate inside the hopper, the internal temperature is low, and the hailstones are large. In this situation, simply heating the collection hopper with a hot air blower results in slow hail melting, leading to poor drainage. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a meteorological monitoring precipitation sampling device. It solves the problem that under harsh conditions, especially when encountering solid precipitation in the form of hail, large hailstones fall into the water collection hopper. Due to the accumulation of hailstones in the collection hopper, the internal temperature is low and the hailstones are large. In this case, simply heating and cooling the water collection hopper with a hot air blower results in slow hailstone melting and poor drainage.
[0005] This utility model proposes a meteorological monitoring precipitation sampling device, including a sampling tube, a collection bucket, multiple pulverizing blades, a stepper motor, and a drive shaft fixedly installed at its output end. The sampling tube has an open top structure and a through hole in its side wall. The collection bucket is fixedly installed at the top opening of the sampling tube, with its tip extending downward into the inside of the sampling tube. The stepper motor is fixedly installed at the bottom of the inner wall of the sampling tube. The drive shaft extends into the inside of the collection bucket. The pulverizing blades are fixedly installed on the drive shaft and located inside the collection bucket. The size of the multiple pulverizing blades increases from bottom to top.
[0006] Furthermore, a heat-conducting hopper is fixedly connected to the inner wall of the collection cylinder, and the heat-conducting hopper is fitted around the bottom of the collection hopper and contacts its conical surface.
[0007] Furthermore, a heating wire is fixedly installed on the outer wall of the heat-conducting bucket, and the heating wire is arranged along a conical spiral.
[0008] Furthermore, a partition plate is fixedly connected to the inner wall of the collection tube, and a sealing ring is fixedly connected to the inner wall of the partition plate. The sealing ring is fitted onto the drive shaft and seals the drive shaft.
[0009] Furthermore, a liquid guiding hopper is fixedly connected to the inner wall of the partition plate, and a liquid guiding pipe is fixedly connected to the inner wall of the heat guiding hopper. The liquid guiding pipe passes through the heat guiding hopper and extends to its outer side, with the end of the liquid guiding pipe extending into the liquid guiding hopper.
[0010] Furthermore, the end of the drive shaft passes through the liquid guide tube and is rotatably connected to it. A drain hole is provided at the top of the liquid guide tube. A partition plate is fixedly connected to the opening on the side wall of the collection tube. A collection tank is placed at the opening on the side wall of the collection tube, and the collection tank is located below the liquid guide hopper.
[0011] Furthermore, a fixing plate is fixedly connected to the inner wall of the collection hopper, a support rod is fixedly connected to the top of the fixing plate, a limit sleeve is fixedly connected to the outer wall of the support rod, a buffer spring is sleeved on the outer wall of the support rod, a limit cover is fixedly connected to the top of the support rod, and an anti-collision bucket is slidably connected to the outer wall of the support rod.
[0012] Furthermore, the top of the buffer spring abuts against the anti-collision bucket, and the bottom of the buffer spring abuts against the limiting sleeve.
[0013] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:
[0014] 1. When encountering solid precipitation in the form of hail, a stepper motor drives the drive shaft to rotate, which in turn drives multiple pulverizing blades to rotate. The pulverizing blades pulverize the hail, thereby reducing its volume and promoting the movement of the pulverized hail. This design can further accelerate the melting of solid precipitation by heating the pulverized hail, thus avoiding poor drainage caused by low temperatures.
[0015] 2. The heating wire heats the heat-conducting bucket quickly and evenly. At this time, the creeping ice fragments can fully contact the heat-conducting bucket, thereby increasing the melting speed of the ice fragments.
[0016] 3. The anti-collision bucket blocks the hail. Under the elastic force of the buffer spring, it can reduce the instantaneous impact force when the hail falls. When the hail falls into the collection bucket, it can prevent the hail from directly contacting the crushing blade and causing damage to the crushing blade. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-3 As shown, a meteorological monitoring precipitation sampling device includes a sampling cylinder 1, a collection bucket 5, multiple pulverizing blades 4, a stepper motor 2, and a drive shaft 3 fixedly installed at its output end. The sampling cylinder 1 has an open top structure and a through hole in the side wall. The collection bucket 5 is fixedly installed at the top opening of the sampling cylinder 1, with the tip of the collection bucket 5 extending downward into the inside of the sampling cylinder 1. The stepper motor 2 is fixedly installed at the bottom of the inner wall of the sampling cylinder 1. The drive shaft 3 extends into the inside of the collection bucket 5. The pulverizing blades 4 are fixedly installed on the drive shaft 3 and located inside the collection bucket 5. The size of the multiple pulverizing blades 4 increases from bottom to top.
[0025] In the above structure, the collection hopper 5 can collect both liquid and solid precipitation in a concentrated manner, while reducing the impact of hailstones being ejected from the collection hopper 5 during hailfall; the stepper motor 2 drives multiple crushing blades 4 to rotate via the drive shaft 3, thereby effectively crushing the hailstones. The multiple crushing blades 4, whose size increases from bottom to top, can gradually crush the hailstones, thereby reducing the volume of the hailstones and increasing the melting speed of the hailstones.
[0026] like Figure 2 As shown, a heat-conducting bucket 6 is fixedly connected to the inner wall of the collection cylinder 1. The heat-conducting bucket 6 is fitted around the bottom of the collection bucket 5 and contacts its conical surface.
[0027] In the above structure, the full contact between the heat-conducting hopper 6 and the collecting hopper 5 can effectively transfer heat, thereby accelerating the melting of hail.
[0028] like Figure 2 As shown, a heating wire 7 is fixedly installed on the outer wall of the heat-conducting bucket 6, and the heating wire 7 is arranged along a conical spiral.
[0029] In the above structure, the heating wire 7, which is installed in a conical spiral, can quickly and evenly heat the heat-conducting bucket 6.
[0030] like Figure 2 As shown, a partition plate 16 is fixedly connected to the inner wall of the collection tube 1, and a sealing ring 17 is fixedly connected to the inner wall of the partition plate 16. The sealing ring 17 is sleeved on the drive shaft 3 and seals the drive shaft 3.
[0031] In the above structure, the drive shaft 3 is sealed by the sealing ring 17.
[0032] like Figure 2 As shown, a liquid guide hopper 18 is fixedly connected to the inner wall of the partition plate 16, and a liquid guide pipe 14 is fixedly connected to the inner wall of the heat conduction hopper 6. The liquid guide pipe 14 passes through the heat conduction hopper 6 and extends to its outer side, with the end of the liquid guide pipe 14 extending into the liquid guide hopper 18.
[0033] like Figure 2 As shown, the end of the drive shaft 3 passes through the liquid guide tube 14 and is rotatably connected to it. A drain hole 15 is provided at the top of the liquid guide tube 14. A partition plate 20 is fixedly connected to the opening on the side wall of the collection tube 1. A collection tank 19 is placed at the opening on the side wall of the collection tube 1. The collection tank 19 is located below the liquid guide hopper 18.
[0034] like Figure 4 As shown, a fixed plate 8 is fixedly connected to the inner wall of the collection hopper 5, a support rod 9 is fixedly connected to the top of the fixed plate 8, a limit sleeve 10 is fixedly connected to the outer wall of the support rod 9, a buffer spring 11 is sleeved on the outer wall of the support rod 9, a limit cover 12 is fixedly connected to the top of the support rod 9, and an anti-collision bucket 13 is slidably connected to the outer wall of the support rod 9. The top of the buffer spring 11 abuts against the anti-collision bucket 13, and the bottom of the buffer spring 11 abuts against the limit sleeve 10.
[0035] In the above structure, the anti-collision bucket 13 blocks the hail. Under the elastic force of the buffer spring 11, the instantaneous impact force of the hail when it falls can be reduced. When the hail falls into the collection bucket 5, it can prevent the hail from directly contacting the crushing blade 4 and causing damage to the crushing blade 4.
[0036] Working principle: When encountering solid precipitation in the form of hail, the stepper motor 2 drives the drive shaft 3 to rotate, which in turn drives multiple pulverizing blades 4 to rotate. The pulverizing blades 4 pulverize the hail, thereby reducing the volume of the hail and promoting the movement of the pulverized hail.
[0037] The heating wire 7 heats the heat-conducting bucket 6. The conical spiral heating wire 7 can quickly and evenly heat the heat-conducting bucket 6. At this time, the creeping ice shards can fully contact the heat-conducting bucket 6, thereby increasing the melting speed of the ice shards.
[0038] After melting into water, it is discharged into the liquid hopper 18 through the liquid guide pipe 14, and then flows into the collection tank 19 through the liquid guide hopper 18, where it is collected in a centralized manner.
[0039] When hail falls into the collection hopper 5, it can prevent hail from directly contacting the crushing blade 4 and causing damage to the crushing blade 4. The anti-collision hopper 13 blocks the hail, and under the elastic force of the buffer spring 11, it can reduce the instantaneous impact force when the hail falls.
[0040] This invention is applicable to areas where hail is frequent, such as plateaus or areas with strong convective climates.
[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
