Description

Technical Field

[0001] This utility model relates to the field of rain gauge technology, and in particular to a frost-resistant tipping bucket rain gauge. Background Technology

[0002] A tipping bucket rain gauge is a commonly used rain measurement instrument in meteorology, environmental monitoring, and water resource management. Its basic working principle involves a tipping bucket device; whenever a certain amount of precipitation passes through the rain gauge, the bucket automatically tilts, triggering a counter to record one tip, thus accumulating the precipitation. This type of rain gauge is widely used in various environments due to its simple structure, low cost, and ease of installation and maintenance, and is particularly suitable for long-term continuous precipitation monitoring. Announcement No. CN221039471U discloses a tipping bucket rain gauge, relating to the field of rain gauge technology. This utility model relates to the field of rain gauge technology and discloses a tipping bucket rain gauge, further comprising: a first measuring mechanism, an adjusting mechanism, and a second measuring mechanism. The bottom end of the device body is threadedly connected to the side of the adjusting mechanism, the inner wall of the side of the device body is fixedly connected to the side of the first measuring mechanism, and the side of the second measuring mechanism is fixedly connected to the inner wall of the side of the device body. In this utility model, the bottom end of the anti-slip base contacts the ground. Based on the level detection device, the corresponding knob is rotated to drive the threaded rod to rotate, causing the threaded rod to move up and down through the thread, thus adjusting the level of the base. The angle is adjusted to keep the base parallel to the horizontal plane. Rainwater falls through the top of the housing into the first measuring mechanism for measurement, and the measured rainwater falls into the second measuring mechanism for secondary measurement. This helps improve the stability of the equipment and the accuracy of the measurement results. However, replacing the tipping bucket of this rain gauge requires a complicated disassembly procedure and a long operation time. It relies on the use of multiple tools, and operators must perform cumbersome steps, which leads to low maintenance efficiency. In cases where a quick return to normal operation is needed, it may cause excessive downtime. This problem increases the difficulty of equipment maintenance and raises maintenance costs. It may also affect the normal operation of the equipment in harsh environments, and improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0004] This utility model adopts the following technical solution: a frost-resistant tipping bucket rain gauge, including a base plate, an outer shell connected internally to the base plate, an anti-freezing layer fixedly installed inside the outer shell, a top plate fixedly installed at the top of the outer shell, a sieve plate slidably connected inside the top plate, a water inlet funnel fixedly installed on the lower surface of the top plate, a fine sieve fixedly installed at the bottom end of the water inlet funnel, a water inlet pipe fixedly installed at the bottom end of the water inlet funnel, a tipping bucket frame fixedly installed on the surface of the water inlet pipe, a side plate fixedly installed on the side of the tipping bucket frame, and a counter fixedly installed on the surface of the side plate. A reed switch is fixedly installed on the surface of the bucket frame. A sliding rod is fixedly installed on the inner side of the bucket frame. A mounting plate is slidably connected to the surface of the sliding rod. A fixing rod is slidably connected to the bottom end of the mounting plate. A spring is fixedly installed on the side of the mounting plate. A cross plate is slidably connected inside the mounting plate. A fixing plate is fixedly installed on the side of the cross plate. A tipping component is fixedly installed on the side of the fixing plate. A balance platform is fixedly installed at the bottom end of the bucket frame. A level is fixedly installed on the surface of the balance platform. A water collection cylinder is fixedly installed on the surface of the bottom plate. A drain pipe is fixedly installed at the bottom end of the water collection cylinder.

[0005] Preferably, the lower surface of the fine screen is fixedly connected to one end of the water inlet pipe, and the surface of the drain pipe is fixedly connected to the interior of the base plate. This prevents debris from entering and guides rainwater smoothly into the tipping bucket through the water inlet pipe. The drain pipe design ensures that accumulated water can be quickly discharged, preventing water flow blockage that could affect measurements or cause icing.

[0006] Preferably, one end of the spring is slidably connected to the inner side of the fixed plate, and the fixing rod is fixedly installed inside the fixed plate. Here, when the bucket tilts, the supporting force and elastic adjustment of the spring help the mounting plate to move stably, avoiding jamming or inability to operate smoothly. Through the force of the spring, the mounting plate can cooperate with the cross plate and the fixing rod with appropriate force, ensuring the accuracy and response speed of the bucket tilting action.

[0007] Preferably, the bottom end of the mounting plate is slidably connected to the inner side of the fixing plate, the springs are evenly distributed on the side of the mounting plate, and the fixing rods are evenly distributed inside the fixing plate. Here, the slidable connection between the mounting plate and the fixing plate facilitates the installation and replacement of the funnel component. The even distribution of the springs on both sides of the mounting plate increases the stability of the overall structure, makes the installation process of the tipping bucket component more precise, and simplifies the quick replacement and maintenance of the tipping bucket component, thereby improving the maintenance efficiency of the equipment and ensuring that the equipment can be quickly restored to normal operation when necessary.

[0008] Preferably, the lower surface of the base plate is provided with a sliding groove, a sliding block is slidably connected inside the sliding groove, a clamping block is fixedly installed on the lower surface of the sliding block, a reciprocating threaded rod is threadedly connected inside the sliding block, and a rotating disk is fixedly installed at one end of the reciprocating threaded rod. Here, the reciprocating threaded rod, driven by the rotating disk, adapts to rods of different diameters through the cooperation of the sliding block and the clamping block.

[0009] Preferably, the upper surface of the clamping block is slidably connected to the lower surface of the base plate, and one end of the reciprocating threaded rod is rotatably connected to the interior of the slide groove. This allows the tipping bucket rain gauge to be precisely and securely installed on support rods of different diameters. By rotating the disc to drive the reciprocating threaded rod, the sliding block and clamping block can be adjusted according to the rod's diameter, thereby achieving quick and stable installation and disassembly.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. This utility model incorporates a sliding rod, mounting plate, fixing rod, spring, horizontal plate, fixing plate, and tipping bucket component. The mounting plate, by clamping both ends of the tipping bucket component, slides between the mounting plate and the horizontal plate and fixing rod under the force of the spring, enabling quick disassembly of the funnel component and the sliding rod. This allows for rapid replacement and repair of the funnel component, reducing equipment downtime and maintenance costs. The spring force ensures the stability of the mounting plate, while also allowing for easy disassembly when needed, avoiding the hassle of requiring numerous tools or complex procedures. This improves the maintainability of the equipment and ensures the efficient operation of the tipping bucket rain gauge during long-term use.

[0012] 2. This utility model incorporates a sliding groove, a sliding block, a clamping block, a reciprocating threaded rod, and a rotating disk. The rotating disk drives the reciprocating threaded rod to rotate, thereby causing the sliding block and clamping block to move on the surface of the reciprocating threaded rod. The adjusting function of the clamping block ensures that the tipping bucket rain gauge is firmly installed on rods of different specifications, allowing the tipping bucket rain gauge to be quickly and stably installed on rods of different diameters. This avoids installation instability or incompatibility caused by different rod diameters, improves the applicability of the equipment, enables the tipping bucket rain gauge to flexibly adapt to various installation environments, simplifies the installation process, and reduces stability problems caused by improper installation.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1

[0025] Please see Figure 1-7This utility model provides a technical solution: a frost-resistant tipping bucket rain gauge, including a base plate 1, an outer shell 2 internally threaded to the base plate 1, an anti-freezing layer 3 fixedly installed inside the outer shell 2, a top plate 4 fixedly installed at the top of the outer shell 2, a sieve plate 5 slidably connected inside the top plate 4, a water funnel 6 fixedly installed on the lower surface of the top plate 4, a fine sieve 7 fixedly installed at the bottom end of the water funnel 6, a water pipe 8 fixedly installed at the bottom end of the water funnel 6, a tipping frame 9 fixedly installed on the surface of the water pipe 8, a side plate 10 fixedly installed on the side of the tipping frame 9, a counter 11 fixedly installed on the surface of the side plate 10, a reed switch 12 fixedly installed on the surface of the tipping frame 9, a sliding rod 13 fixedly installed on the inner side of the tipping frame 9, a mounting plate 14 slidably connected to the surface of the sliding rod 13, a fixing rod 15 slidably connected to the bottom end of the mounting plate 14, a spring 16 fixedly installed on the side of the mounting plate 14, and a horizontal plate 17 slidably connected inside the mounting plate 14. A fixing plate 18 is fixedly installed on the side of plate 17, and a tipping bucket component 19 is fixedly installed on the side of fixing plate 18. A balance platform 20 is fixedly installed at the bottom of tipping bucket frame 9, and a level 21 is fixedly installed on the surface of balance platform 20. A water collection cylinder 22 is fixedly installed on the surface of base plate 1, and a drain pipe 23 is fixedly installed at the bottom of water collection cylinder 22. By setting an outer shell 2 and an antifreeze layer 3 inside the base plate 1, the equipment can be ensured to operate stably in low-temperature environments. The antifreeze layer 3 inside the outer shell 2 can effectively isolate the influence of cold air on the key components inside the equipment and prevent freezing. The sieve plate 5 slidably connected to the top plate 4 can effectively filter impurities and ensure that rainwater flows smoothly into the water inlet funnel 6 to avoid clogging. The connection between the water inlet funnel 6 and the fine screen 7 can guide rainwater to flow smoothly into the water inlet pipe 8, while effectively preventing impurities from entering the system and reducing the risk of failure. The counter 11 and the reed switch 12 enable the rain gauge to efficiently record precipitation data.

[0026] The lower surface of the fine screen 7 is fixedly connected to one end of the water inlet pipe 8, and the surface of the drain pipe 23 is fixedly connected to the inside of the base plate 1. This prevents debris from entering and guides rainwater to flow smoothly into the tipping bucket through the water inlet pipe 8. The drain pipe 23 ensures that accumulated water can be discharged quickly, avoiding the impact of water flow blockage on measurement or the occurrence of icing. One end of the spring 16 is slidably connected to the inside of the fixing plate 18, and the fixing rod 15 is fixedly installed inside the fixing plate 18. When the tipping bucket is tilted, the supporting force and elastic adjustment of the spring 16 help the mounting plate 14 to move stably, avoiding jamming or inability to operate smoothly. Through the force of the spring 16, the mounting plate 14 can cooperate with the horizontal plate 17 and the fixing rod 15 with appropriate force to ensure the accuracy and response speed of the tipping action. The bottom end of the mounting plate 14 is slidably connected to the inner side of the fixing plate 18. The springs 16 are evenly distributed on the side of the mounting plate 14, and the fixing rods 15 are evenly distributed inside the fixing plate 18. The sliding connection between the mounting plate 14 and the fixing plate 18 makes the installation and replacement of the funnel component more convenient. The even distribution of the springs 16 on both sides of the mounting plate 14 increases the stability of the overall structure, makes the installation process of the tipping component 19 more precise, makes the quick replacement and maintenance of the tipping component 19 easier, improves the maintenance efficiency of the equipment, and ensures that the equipment can be quickly restored to normal operation when necessary.

[0027] Example 2

[0028] Please see Figure 5 The lower surface of the base plate 1 has a groove 24, and a sliding block 25 is slidably connected inside the groove 24. A clamping block 26 is fixedly installed on the lower surface of the sliding block 25. A reciprocating threaded rod 27 is threadedly connected inside the sliding block 25. A rotating disk 28 is fixedly installed at one end of the reciprocating threaded rod 27. Driven by the rotating disk 28, the reciprocating threaded rod 27 adapts to rods of different diameters with the cooperation of the sliding block 25 and the clamping block 26. The upper surface of the clamping block 26 is slidably connected to the lower surface of the base plate 1, and one end of the reciprocating threaded rod 27 is rotatably connected to the inside of the groove 24, enabling the tipping bucket rain gauge to be accurately and stably installed on support rods of different diameters. By rotating the rotating disk 28 to drive the reciprocating threaded rod 27, the sliding block 25 and the clamping block 26 can be adjusted according to the diameter of the rod, thereby achieving quick and stable installation and disassembly.

[0029] Working principle: During rainfall, rainwater passes through the sieve plate 5 of the top plate 4 to filter large particles of debris before entering the water inlet funnel 6. It then undergoes secondary filtration through the fine sieve 7 to prevent blockage by ice crystals or impurities. The filtered water flows through the water inlet pipe 8 to the tipping bucket 19. The tipping bucket 19 is flexibly installed via a sliding connection structure between the slide rod 13 and the mounting plate 14. When one side of the tipping bucket is full of rainwater, gravity triggers the tipping bucket to flip around the fulcrum of the horizontal plate 17 and the fixed plate 18, pouring the rainwater into the water collection cylinder 22. Simultaneously, the other side of the tipping bucket begins to collect water. Each flip triggers the reed switch 12 via magnetic attraction. The counter 11 records the number of flips and converts it into rainfall data. The poured rainwater is quickly discharged through the drain pipe 23 to prevent water accumulation and freezing. The antifreeze layer 3 on the inner wall of the outer shell 2 isolates the water from the external low temperature, reducing the risk of freezing. During installation, rotating the rotating disk 28 drives the reciprocating threaded rod 27, causing the clamping block 26 to synchronously contract or expand along the sliding groove 24, adapting to support rods of different diameters and locking them in place. Maintenance of the tipping bucket 19 is achieved by squeezing both sides of the mounting plate 14, which, through the elasticity of the spring 16, allows the mounting plate 14 to be installed with the slide rod 13. This enables quick disassembly of the tipping bucket 19 for cleaning or replacement, significantly shortening maintenance time.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
