[0002] In the prior art, an automatic rainfall sampler is a device used to automatically collect and record rainfall data, and is widely used in the fields of meteorological observation, environmental monitoring, agricultural research, etc. These devices generally include a rain funnel for collecting rainwater; a dust cover to protect the funnel from dust pollution when it is not raining; a drive structure responsible for opening and closing the dust cover; and a rain gauge and rain sensor for measuring rainfall and detecting the start and end of rainfall, respectively. All these components are usually integrated in a cabinet and managed by a control system that is responsible for controlling the opening and closing of the dust cover, recording rainfall data, and generating log files. These samplers are usually placed in outdoor environments, such as weather stations, farmlands, or urban parks, to monitor and analyze rainfall patterns.

[0003] Since the drive structure and other key components of the dust cover are usually integrated inside the cabinet, the maintenance and repair of the equipment becomes more complicated and time-consuming. When the internal mechanical parts are damaged, maintenance and repairs when a failure occurs require people to drill into the cabinet, and operating in a small cabinet causes great inconvenience to personal safety and use, and increases the difficulty and cost of maintenance. The failure of the internal drive structure may directly affect the normal operation of the sampler, and then affect the accuracy and reliability of the data. Utility Model Content

[0006] In a feasible implementation manner, a sampling cylinder is arranged in the lower space of the cabinet.

[0007] In a feasible embodiment, the driving structure includes: a shell, which is fixedly arranged on the top of the cabinet; a cover plate, which is installed on the top of the shell by a plurality of screws; a rotating member, the ends of the two rotating members are respectively rotatably installed inside the shell along their own axes, and both ends pass through the outside of the outer wall of the shell; a linkage component, which is arranged on the outside of the outer walls of the two rotating members and the outer wall surface of the shell.

During inspection and maintenance, the maintenance personnel only need to open the upper cover of the drive system to easily perform maintenance, refueling or replace spare parts, which greatly simplifies the maintenance process and reduces the complexity and time required for maintenance work. Since the driving structure is physically separated from the rain collecting funnel, the impact of mechanical failures on the overall performance of the sampler is reduced.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a structurally improved rainfall automatic sampler, comprising: a cabinet 1, a partition 2, a control system, a rain gauge 3, a rain collecting funnel 4, a rain sensing sensor 5, a driving structure and a dust cover 6. The cabinet 1 is provided with a cavity structure inside, and the front side of the cabinet 1 is provided with an opening door; the partition 2 is arranged inside the cabinet 1, and the partition 2 divides the interior of the cabinet 1 into an upper space and a lower space; the control system is arranged in the upper space of the cabinet 1; two rain gauges 3 are respectively arranged at the ends of the cabinet 1, and are symmetrically arranged respectively; the rain collecting funnel 4 is arranged at the top of the cabinet 1 by a plurality of screws; the rain sensing sensor 5 is arranged at the top of the cabinet 1; the driving structure is arranged at the top of the outside of the cabinet 1; the dust cover 6 is arranged on the driving end of the driving structure, and the bottom surface is in contact with the open mouth at the top of the rain collecting funnel 4.

[0018] In the specific implementation process, it should be noted that the automatic rainfall sampler is composed of a cabinet 1 with a cavity structure inside. The front side of the cabinet 1 is provided with an openable door. The interior of the cabinet 1 is divided into two spaces, upper and lower, by a partition 2. A control system is installed in the upper space for managing various functions and operations of the sampler. A rain gauge 3 is provided at each end of the cabinet 1 and arranged symmetrically for accurately measuring rainfall. A rain funnel 4 is fastened by multiple screws for collecting rainwater samples. A rain sensor 5 is also installed on the top of the cabinet 1 for detecting rainfall. At the beginning and end of the rain, a driving structure is provided at the top of the outside of the cabinet 1. The function of the driving structure is to control the dust cover 6 located on its driving end. The dust cover 6 protects the rain collecting funnel 4 from dust pollution when there is no rainfall. When the rain sensor 5 detects rainfall, the control system will activate the driving structure to drive the dust cover 6 to open, so that rainwater can smoothly enter the rain collecting funnel 4 and be collected, ensuring the accurate collection of rainfall samples. Moreover, since the dust cover 6 is located outside the cabinet 1, the inspection and maintenance operations are simpler and safer, effectively reducing the safety risks during use.

[0019] In some examples, further, a sampling cylinder is provided in the lower space of the cabinet 1, and the bottom end of the rain funnel 4 is connected to a rainwater passage pipe 14, which corresponds to the tube mouth of the collection cylinder. After the rainwater is collected by the rain funnel 4, it flows into the sampling cylinder through the rainwater passage pipe 14 connected to the bottom end of the rain funnel 4. The collected rainwater samples can be automatically transmitted to the sampling cylinder directly through the control system, which is convenient for subsequent analysis and processing. The driving structure at the top of the cabinet 1 controls a dust cover 6, which covers the rain funnel 4 when there is no rainfall to prevent dust and other impurities from entering. When the rain sensor 5 detects rainfall, the control system activates the driving structure to open the dust cover 6, and the rainwater can smoothly pass through the rain funnel 4 and the rainwater passage pipe 14, and finally collect in the sampling cylinder. It ensures the effective collection of rainfall samples, facilitates the maintenance and safe operation of the equipment, and reduces the safety risks in use.

[0020] In some examples, further, the driving structure includes: a shell 7, a cover plate 8, a rotating member 9 and a linkage assembly, the shell 7 is fixedly arranged at the top of the cabinet 1; the cover plate 8 is installed at the top of the shell 7 by a plurality of screws; the ends of the two rotating members 9 can be rotatably installed inside the shell 7 along their own axes, and both ends pass through the outside of the outer wall of the shell 7; the linkage assembly is arranged on the outside of the outer walls of the two rotating members 9 and the outer wall surface of the shell 7.

[0021] In the specific implementation process, it should be noted that the housing 7 is fixedly mounted on the top of the cabinet 1. At the top of the housing 7, the cover plate 8 is used to protect the mechanical parts inside the housing 7 from the influence of the external environment, such as rain, dust, etc. At the same time, it is convenient to disassemble the cover plate 8 to more conveniently maintain or replace the parts inside it. The two rotating parts 9 can rotate smoothly under the drive of the linkage assembly when receiving the control command. The rotating part 9 is connected to the linkage assembly. The linkage assembly plays the role of transmitting power and providing power. When the rain sensor 5 detects rainfall, the control system sends a signal to activate the drive structure. The rotating part 9 starts to rotate, and through the action of the linkage assembly, the dust cover 6 is driven to open. Rainwater can smoothly enter the rainwater passage pipeline 14 below through the rain funnel 4, and finally collect in the sampling tube for sampling. When the rainfall stops, the control system sends a signal again, and the drive structure works to close the dust cover 6 to protect the rain funnel 4 from pollution. It ensures that the sampler can operate effectively in both rainwater collection and non-collection states, and it is also convenient for the maintenance and operation safety of the equipment.

[0022] In some examples, further, the linkage assembly includes: a driving motor 10, a driving gear 11, a driven gear 12 and a connecting rod 13, the driving motor 10 is fixedly mounted at the bottom end inside the shell 7; the driving gear 11 is fixedly mounted on the driving end of the driving motor 10; the driven gear 12 is sleeved on the outer side of the outer wall of one of the two rotating parts 9, and is meshed with the driving gear 11; a plurality of connecting rods 13 are fixedly mounted on the ends of the two rotating parts 9 in a group of two, and the other end is movably connected to the dust cover 6.

[0023] In the specific implementation process, it should be noted that the role of the linkage assembly is to control the opening and closing action of the dust cover 6, to ensure that rainwater can be collected when needed, and to protect the rain funnel 4 from pollution when it is not necessary to collect. A driving gear 11 is installed on the driving end of the drive motor 10. When the drive motor 10 is started, the driving gear 11 starts to rotate. A driven gear 12 meshing with it starts to rotate. When the driving gear 11 rotates, it will drive the driven gear 12 to rotate, and then drive the rotating member 9 to rotate. The other end of a number of linkage rods 13 is movably connected to the dust cover 6. When the rotating member 9 starts to rotate, the linkage rod 13 also moves accordingly, thereby driving the dust cover 6 to perform corresponding opening and closing actions. When the rain sensor 5 detects rainfall, the control system will activate the drive motor 10 to rotate the driving gear 11, and then drive the dust cover 6 to open through the cooperation of the driven gear 12 and the linkage rod 13, so that rainwater can smoothly enter the rain funnel 4. After the rainfall ends, the control system instructs the drive motor 10 to flip again and close the dust cover 6 to protect the rain collecting funnel 4 from being polluted by impurities such as dust. While the sampler automatically collects rainwater, it can also effectively protect itself when not working, ensuring the purity and reliability of the collected rainwater samples.

[0024] In some examples, further, the inclination directions of several linkage rods 13 are consistent and are distributed in a parallelogram shape. The inclined arrangement of the linkage rods 13 not only ensures the stability and uniform force of the linkage rods 13, but also helps to control the movement of the dust cover 6 more accurately and in a coordinated manner. When the rain sensor 5 detects rainfall, the control system will instruct the drive motor 10 to start, so that the driving gear 11 starts to rotate. The rotational motion is transmitted to the driven gear 12, and further transmitted to the linkage rod 13 through the rotating member 9. Since all the linkage rods 13 have the same inclination direction and are distributed in a parallelogram shape, the linkage rods 13 will work together to push the dust cover 6 to open smoothly and in a coordinated manner. The dust cover 6 ensures the protection of the rain funnel 4 and other sensitive components inside the cabinet 1. This improves the operating efficiency of the sampler and enhances its stability and reliability under different environmental conditions.
