Description

A rainfall collection device Technical Field

[0001] This utility model relates to the field of rain gauge technology, and more specifically, to a rain gauge collection device. Background Technology

[0002] A rain gauge, also known as a rain meter or rain gauge, is an instrument used in meteorological and hydrological monitoring to measure precipitation in a region over a period of time. Common types include siphon-type and tipping bucket-type. The core of a tipping bucket rain gauge is a tipping bucket with a central partition. When the rainwater collected on one side of the bucket reaches a preset value, gravity causes the bucket to tip over instantly, emptying the water. Simultaneously, an electrical signal is triggered via a reed switch or Hall effect sensor. By recording the number of tipping bucket rotations, the total rainfall can be calculated. Tipping bucket rain gauges can transmit data in real time, facilitating the construction of automated weather station networks. Currently, tipping bucket rain gauges are widely used in the meteorological monitoring industry due to their ease of electrical signal transmission.

[0003] Because tipping bucket rain gauges measure rainwater by mechanically tilting the bucket, with each tilt corresponding to a fixed amount of rainfall, they require a high degree of levelness in the water platform on which they are installed. However, in some remote mountainous areas, there is a lack of fixed water platforms for tipping bucket rain gauges, which limits their widespread use. Summary of the Invention

[0007] The controller is used to collect the tilting signal of the tipping bucket, and the controller is equipped with a gyroscope attitude sensor chip and indicator lights;

[0008] The support mechanism is provided in n sets. The support mechanism and the base are rotatably connected. When the support mechanism rotates, the support mechanism can be stored in the first storage slot or the second storage slot, where n≥3.

[0009] According to some embodiments of the present invention, each set of support mechanisms includes a first leg and a second leg, the first leg and the base are rotatably connected, and the second leg can be moved and adjusted along the length direction of the first leg.

A first protruding rib is provided along the axial direction on the outer peripheral wall of the rain collection hopper. A first groove is provided on the upper inner peripheral wall of the outer cylinder body corresponding to the first protruding rib.

[0018] A rainfall collection device according to an embodiment of the present utility model has at least the following beneficial effects:

[0019] According to the present invention, the rainfall collection device includes a base, a controller, and a support mechanism. A tipping bucket is rotatably mounted on the base; a first storage groove is provided on the outer peripheral wall of the base; a protective cover is detachably mounted on the upper end of the base, and a second storage groove is provided on the protective cover; the controller is used to collect the tipping bucket's tilting signal, and the controller is equipped with a gyroscope attitude sensor chip and an indicator light; the support mechanism is rotatably connected to the base. When rotating, the support mechanism can be stored in either the first or second storage groove. Specifically, under normal conditions, the support mechanism is stored in the second storage groove for transportation or installation on a water platform via the base. When deployed in the field, the support mechanism is stored in the first storage groove and extends to the outside of the base, forming a support leg. During support, the gyroscope attitude sensor chip detects the attitude of the base. When the base is placed horizontally, the controller receives a signal and controls the indicator light to illuminate. Through this structural design, electronic sensing technology and mechanical structure are integrated, significantly improving the deployment efficiency, measurement accuracy, and environmental adaptability of traditional tipping bucket rain gauges. The device uses a gyroscope attitude sensor chip to monitor the base tilt angle data in real time with an accuracy of ±0.05°. When the base reaches a level position, the controller drives the indicator light to emit an optical signal, realizing real-time visual calibration during the installation process. This design eliminates the subjective error of traditional manual leveling, fundamentally avoiding the problems of tipping bucket volume deviation and tipping lag caused by tilt angle, and ensuring data reliability in complex environments.

[0020] According to the present invention, the support mechanism adopts a dual-mode adaptive design: in the transport or fixed installation state, it is stored entirely in the second storage slot on the top of the protective cover, avoiding damage during handling and reducing volume; during field operations, it moves into the first storage slot on the side wall of the base and extends into a triangular support structure, which can quickly complete the form transformation and form a stable support without the need for external tools. This solution effectively solves the deployment problem of traditional tripods in muddy, sloping, and other terrains, and improves the adaptability to harsh environments. Attached Figure Description

[0033] Referring to Figures 1 to 3, this utility model discloses a rainfall collection device, which includes a base 100, a controller 200, and a support mechanism 300. A tipping bucket 110 is rotatably mounted on the base 100; a first storage groove 101 is provided on the outer peripheral wall of the base 100; a protective cover 120 is detachably mounted on the upper end of the base 100, and a second storage groove 121 is provided on the protective cover 120; the controller 200 is used to collect the flipping signal of the tipping bucket 110, and the controller 200 is equipped with a gyroscope attitude sensor chip and an indicator light; the support mechanism 300 and the base 100 rotate... In this embodiment, the support mechanism 300 is provided in three sets to form a stable triangular support. Correspondingly, the first storage slot 101 and the second storage slot 121 are also provided in three sets. When the support mechanism 300 rotates, it can be stored in either the first storage slot 101 or the second storage slot 121. Specifically, under normal conditions, the support mechanism 300 is stored in the second storage slot 121 for transportation or installation on a water platform via the base 100. When deployed in the field, the support mechanism 300 is stored in the first storage slot 101 and extends to the outside of the base 100, forming a foot support. During support, the gyroscope attitude sensor chip detects the attitude of the base 100. When the base 100 is placed horizontally, the controller 200 receives a signal and controls the indicator light to illuminate. Through the design of this structure, electronic sensing technology and mechanical structure are integrated, significantly improving the deployment efficiency, measurement accuracy, and environmental adaptability of the traditional tipping bucket 110 rain gauge. The device uses a gyroscope attitude sensor chip to monitor the tilt angle data of the base 100 in real time with an accuracy of ±0.05°. When the base 100 reaches a level state, the controller 200 drives the indicator light to emit an optical signal, realizing real-time visual calibration during the installation process. This design eliminates the subjective error of traditional manual leveling, fundamentally avoiding the volume deviation and tilting lag problems of the tipping bucket 110 caused by tilt angle, and ensuring data reliability in complex environments.

[0034] In this embodiment, the support mechanism 300 adopts a dual-mode adaptive design: in the transport or fixed installation state, it is completely stored in the second storage slot 121 on the top of the protective cover 120, avoiding damage during handling and reducing volume; during field operations, it moves into the first storage slot 101 on the side wall of the base 100 and extends into a triangular support structure, which can quickly complete the form transformation and form a stable support without external tools. This solution effectively solves the deployment problem of traditional supports in complex terrain and improves the adaptability to harsh environments.

[0035] In some embodiments of this utility model, each support mechanism 300 includes a first leg 310 and a second leg 320. The first leg 310 is rotatably connected to the base 100, and the second leg 320 can be adjusted along the length of the first leg 310. Specifically, in this embodiment, when the device is deployed on a non-horizontal surface, the operator first rotates the first leg 310 to unfold it from the second storage slot 121 into the first storage slot 101, and then controls the second leg 320 to extend and retract. By changing the extension length of the second leg 320, the height difference of each leg can be adjusted independently. Combined with the gyroscope attitude sensor integrated in the base 100, precise horizontal calibration in three-dimensional space can be achieved. After leveling is completed...

[0036] In some embodiments of this utility model, the first leg 310 and the second leg 320 are threadedly connected. Specifically, in this embodiment, the threaded connection between the first leg 310 and the second leg 320 improves the adjustment accuracy of the total length of the support mechanism 300, thereby enhancing the stability of the support in complex outdoor environments.

[0037] In some embodiments of this utility model, a threaded hole 311 is provided on the first support leg 310, and a preload spring 312 is provided at the bottom of the threaded hole 311. Specifically, in this embodiment, after adjusting the relative positions of the first support leg 310 and the second support leg 320, the preload spring 312 abuts against the end of the second support leg 320. The preload spring 312 can prevent the second support leg 320 from rotating relative to the first support leg 310, thereby improving the stability of the device during long-term use.

[0038] In some embodiments of this utility model, the end of the second leg 320 away from the first leg 310 is provided with an inverted conical structure 321. Specifically, in this embodiment, the inverted conical structure 321 of the first leg 310 can securely insert the first leg 310 into the soft soil layer, thereby improving the applicability of this device.

[0039] In some embodiments of this invention, a plurality of reinforcing ribs 322 are provided on the outer peripheral wall of the second leg 320. Specifically, in this embodiment, the structural strength of the second leg 320 can be improved by providing reinforcing ribs 322, thereby improving stability and the service life of the device.

[0040] In some embodiments of this utility model, an outer cylinder 400 is also included. A rain collection hopper 130 is detachably provided at the upper end of the protective cover 120. A first protruding rib 131 is provided axially on the outer peripheral wall of the rain collection hopper 130. A first groove 411 is provided on the upper inner peripheral wall of the outer cylinder 400 corresponding to the first protruding rib 131. The first protruding rib 131 and the first groove 411 are slidably connected. Specifically, in this embodiment, since the diameter of the connection between the rain collection hopper 130 and the protective cover 120 is small, the rain collection hopper 130 can be stably fixed on the protective cover 120 by the outer cylinder 400.

[0041] In some embodiments of this utility model, the outer peripheral wall of the protective cover 120 is provided with a second protruding rib 122 along the axial direction, and the inner peripheral wall of the lower part of the outer cylinder 400 is provided with a second groove 421 corresponding to the second protruding rib 122. The second protruding rib 122 and the second groove 421 are slidably connected. Specifically, in this embodiment, the rain collection hopper 130 can be stably fixed on the protective cover 120 by the outer cylinder 400. In addition, during the axial sliding process of the outer cylinder 400, the outer cylinder 400 can act as a limit for the opening direction of the first storage groove 101 or the second storage groove 121. When the support mechanism 300 is located in the first storage groove 101 or the second storage groove 121, the support mechanism 300 can be released or fixed by sliding the outer cylinder 400.

[0042] In some embodiments of this utility model, the outer cylinder 400 includes a first cylinder portion 410 and a second cylinder portion 420. A first groove 411 is disposed on the first cylinder portion 410, and a second groove 421 is disposed on the second cylinder portion 420. The inner diameter of the first cylinder portion 410 is smaller than the inner diameter of the second cylinder portion 420. Specifically, in this embodiment, through the design of this mechanism, the outer cylinder 400 can cover the outside of this device. This not only protects the internal core components but also, due to its stepped structure, provides better structural strength.

[0043] In some embodiments of this utility model, an elastic pad 430 is provided on the second cylindrical portion 420 corresponding to the storage position of the support mechanism 300. Specifically, in this embodiment, the elastic pad 430 prevents rigid contact between the outer cylindrical body 400 and the support mechanism 300.

[0044] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
