Description

Technical Field

[0001] This utility model belongs to the field of hydrological and water conservancy equipment technology, specifically relating to a rain gauge for hydrological monitoring. Background Technology

[0002] Rain gauges are commonly used devices in hydrological monitoring, widely applied in meteorological observation, flood warning, and water resource management. Traditional rain gauges primarily collect rainfall directly through a container, measuring it using a scale or electronic sensor. However, in long-term outdoor use, the rain gauge's collection hopper frequently becomes clogged with fallen leaves, dust, and other impurities. This clogging not only affects the normal collection and measurement accuracy of rainwater but also increases the frequency of equipment maintenance and reduces operational efficiency.

[0003] In existing technologies, the common solutions to the problem of rain gauge clogging are adding filters or installing protective covers. While these methods can alleviate the problem of impurity accumulation to some extent, once the clogging occurs, it is difficult to observe and there are no clear warning signs. Cleaning and maintenance after clogging is also quite troublesome, requiring the removal of the protective cover, which can easily damage the internal components. Therefore, it is necessary to improve the structure of the rain gauge. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a rain gauge for hydrological monitoring that provides blockage alerts, reduces maintenance frequency, and improves the stability and service life of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rain gauge for hydrological monitoring includes a measuring cylinder body, an anti-clogging auxiliary hopper, and a main hopper dust cover. A connecting joint is provided on one side of the top of the measuring cylinder body, and a dust cover rocker plate is provided on one side of the main hopper dust cover. The main hopper dust cover covers the top of the measuring cylinder body. The dust cover rocker plate and the connecting joint are movably connected by a rotating shaft. A support rod is welded between the dust cover rocker plate and the anti-clogging auxiliary hopper. A water inlet hole is provided in the center of the anti-clogging auxiliary hopper.

[0007] Furthermore, when the water inlet of the auxiliary hopper becomes blocked, water accumulates inside the auxiliary hopper. Under the action of gravity, the water-blocked auxiliary hopper rotates and flips around the pivot of the dust cover rocker plate to open the dust cover of the main hopper, thus prompting the staff to clean the auxiliary hopper.

[0008] Furthermore, a main water inlet hopper is provided at the top of the measuring cylinder body, a water guide hose is inserted and installed at the bottom of the anti-clogging auxiliary hopper, a pipe head is provided on the upper surface of the dust cover of the main hopper, and the bottom of the water guide hose is inserted and installed at the top of the pipe head.

[0009] Furthermore, the pipe head is connected to the main water inlet hopper, and the water guiding hose is used to connect the anti-clogging auxiliary hopper and the main water inlet hopper.

[0010] Furthermore, the upper surface of the anti-clogging secondary hopper corresponding to the water inlet of the secondary hopper is provided with a secondary hopper leak plate, and the upper surface of the secondary hopper leak plate is uniformly provided with anti-clogging needles. The anti-clogging needles are used to lift up impurities such as fallen leaves to prevent fallen leaves from clogging the through holes on the surface of the secondary hopper leak plate.

[0011] Furthermore, the main water inlet hopper is equipped with a main hopper strainer.

[0012] Furthermore, a support foot is fixed to the bottom of the measuring cylinder body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Firstly, this invention features a linked structure between the anti-clogging auxiliary hopper and the main hopper dust cover. When the anti-clogging auxiliary hopper becomes clogged, the weight of the accumulated water drives it to flip, opening the main hopper dust cover using a lever principle, thus providing timely clogging alerts. This design not only prevents rainwater from being unable to enter the main inlet hopper but also significantly reduces maintenance workload and improves the rain gauge's continuous monitoring capability.

[0015] Secondly, this invention incorporates a hopper funnel plate and anti-clogging pins on its surface within the anti-clogging hopper. These pins effectively lift away impurities such as fallen leaves, preventing large debris from clogging the hopper's water inlet and ensuring smooth rainwater flow. This design enhances filtration capacity while reducing cleaning frequency, improving the equipment's adaptability and lifespan in complex outdoor environments. Attached Figure Description

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4 As shown, a rain gauge for hydrological monitoring includes a measuring cylinder body 101, an anti-clogging auxiliary hopper 103, and a main hopper dust cover 105. A connecting joint 111 is provided on one side of the top of the measuring cylinder body 101, and a dust cover rocker plate 152 is provided on one side of the main hopper dust cover 105. The main hopper dust cover 105 covers the top of the measuring cylinder body 101. The dust cover rocker plate 152 and the connecting joint 111 are movably connected by a rotating shaft. A support rod 104 is welded between the dust cover rocker plate 152 and the anti-clogging auxiliary hopper 103. A secondary hopper water inlet 131 is provided in the center of the anti-clogging auxiliary hopper 103 for rainwater diversion.

[0026] like Figures 1-4 As shown, when the auxiliary water inlet 131 is blocked, water accumulates inside the anti-blockage auxiliary hopper 103. Under the action of gravity, the water-filled anti-blockage auxiliary hopper 103 rotates and flips around the pivot of the dust cover rocker 152 to open the dust cover 105 of the main hopper. This flipping action can significantly remind the staff to clean the impurities inside the anti-blockage auxiliary hopper 103 in time, so as to avoid affecting the accuracy and efficiency of rainfall monitoring.

[0027] like Figures 1-4 As shown, a main water inlet hopper 112 is provided at the top of the measuring cylinder body 101. The opening diameter of the main water inlet hopper 112 is 50 mm, which is used to collect rainwater from the anti-clogging auxiliary hopper 103. A water guiding hose 107 is installed at the bottom of the anti-clogging auxiliary hopper 103 by plugging in. The water guiding hose 107 is made of silicone rubber material, which has good flexibility and weather resistance. The bottom of the water guiding hose 107 is tightly plugged into the pipe head 151 opened at the top of the dust cover 105 of the main hopper. The pipe head 151 has a diameter of 10 mm and is made of corrosion-resistant PVC material. The pipe head 151 is connected to the main water inlet hopper 112 through an internal channel, forming a complete rainwater guiding path to ensure that rainwater can smoothly enter the main water inlet hopper 112.

[0028] like Figures 3-5 As shown, a secondary hopper drain plate 106 is provided at the top of the anti-clogging secondary hopper 103 corresponding to the position of the secondary hopper water inlet 131. The secondary hopper drain plate 106 is made of stainless steel mesh, and its surface is evenly distributed with anti-clogging needles 161 with a diameter of 2 mm. The anti-clogging needles 161 have a vertical height of 20 mm and a distribution spacing of 5 mm, which can effectively lift up larger impurities such as fallen leaves and prevent fallen leaves from clogging the through holes of the secondary hopper drain plate 106. The design of the secondary hopper drain plate 106 extends the cleaning cycle of the rain gauge and improves the practicality of the equipment.

[0029] like Figure 2 and Figure 6 As shown, the main water inlet hopper 112 is equipped with a main hopper strainer 113 inside.

[0030] like Figure 1 As shown, a support foot 102 is fixed to the bottom of the measuring cylinder body 101.

[0031] The working principle of this utility model is as follows:

[0032] First, the measuring cylinder body 101 is set at the hydrological monitoring position to monitor rainfall. When it rains, rainwater falls into the anti-clogging auxiliary hopper 103 and is transported to the main inlet hopper 112 through the water guiding hose 107.

[0033] When dust and impurities fall into the anti-clogging auxiliary hopper 103 and accumulate over time, blocking it and preventing rainwater from flowing into the main inlet hopper 112, the rainwater gathers inside the anti-clogging auxiliary hopper 103. This increases the weight of the auxiliary hopper 103, and ultimately, under its own weight, it opens the main inlet dust cover 105 through a lever principle. The opened anti-clogging auxiliary hopper 103 serves as a reminder to staff, facilitating timely cleaning. Simultaneously, rainwater and dust are first collected and filtered by the anti-clogging auxiliary hopper 103, better protecting the main inlet hopper 112 and eliminating the need for frequent maintenance.

[0034] When fallen leaves enter the anti-clogging secondary hopper 103, the anti-clogging pins 161 on the surface of the secondary hopper's drain plate 106 will lift the fallen leaves, without affecting the rainwater's continued flow into the main inlet hopper 112.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
