Description

Technical Field

[0001] This utility model relates to the field of data collection equipment technology, and in particular to a surface runoff collection device. Background Technology

[0002] Surface runoff and the composition of runoff are important prerequisites and bases for studying farmland nutrient balance, formulating water resource management and non-point source pollution control measures.

[0003] In existing technologies, most surface runoff collection methods are manual and automated. Manual collection relies on human operation, requires constant monitoring of weather changes, poses safety hazards in the field during thunderstorms, and requires transport vehicles or manpower to transport the collection equipment to multiple collection points. Automated collection relies on commercially available automated instruments to automatically collect runoff by setting sampling times.

[0004] Both of these data collection methods still have some problems in use. For example, manual data collection is time-consuming and labor-intensive, and it is difficult to achieve continuous monitoring. In addition, automated data collection generally requires the construction of collection pools, which results in high capital investment and maintenance costs. Furthermore, the effectiveness of data collection cannot be guaranteed in the event of a power outage, making it a high-energy-consuming data collection device. Summary of the Invention

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of the claimed invention.

[0027] Example:

[0028] like Figure 1 As shown, this embodiment provides a surface runoff collection device, including:

[0029] Protective box 1, with a hollow receiving cavity defined inside the protective box 1;

[0030] Sample cell 2 has a hollow collection cavity defined inside it, and a drain outlet is provided at the lower end of the sample cell 2.

[0031] Fixing bracket 3 is used to fix the sample tank 2 in the receiving cavity;

[0032] The runoff collection frame 4 has a water inlet at the upper end of the sample tank 2, and the outlet of the runoff collection frame 4 is connected to the water inlet through the connecting pipe 9.

[0033] In this embodiment, a hollow receiving cavity is defined inside the protective box 1, and a hollow collection cavity is defined inside the sample tank 2. First, the fixing frame 3 is installed in the receiving cavity. Since the fixing frame 3 defines a hollow cavity, the sample tank 2 is installed in the cavity of the fixing frame 3, thereby fixing the sample tank 2 in the receiving cavity through the fixing frame 3. A water inlet is opened at the upper end of the sample tank 2. The water inlet is connected to the outlet of the runoff collection frame 4 through the connecting pipe 9. Therefore, the runoff collection frame 4 is shallowly buried on the ground surface to form a surface runoff collection area. The runoff on the ground flows through the runoff collection frame 4 and the connecting pipe 9 in sequence and enters the sample tank 2. At the same time, since a drain outlet is opened at the lower end of the sample tank 2, the water in the sample tank 2 can be discharged out through the drain outlet. Its structure is simple, easy to carry, does not require external power, and can also effectively reduce the cost of runoff collection.

[0034] Furthermore, it also includes a cover plate 5. The upper end of the sample cell 2 is open, and the cover plate 5 is placed on the open end of the sample cell 2. An observation window is provided on the cover plate 5 to facilitate observation of the sampling situation inside the sample cell 2.

[0035] Preferably, it also includes a stirrer 51, the upper end of which is movably mounted on the cover plate 5, and the lower end of which is provided with blades to stir the water sample in the sample tank 2.

[0036] Specifically, it also includes a sampling tube 52, which is disposed on the cover plate 5, and the lower end of the sampling tube 52 extends at least partially into the receiving cavity.

[0037] Preferably, it also includes a handle 53, which is disposed on the top wall of the cover plate 5.

[0038] Furthermore, it also includes a collection pipe 6, which is detachably installed at the water inlet position. One end of the connecting pipe 9 is connected to the outlet of the runoff collection frame 4, and the other end is connected to the water inlet through the collection pipe 6.

[0039] Preferably, it also includes a water valve 61, which is disposed on the collection pipe 6 to control the opening and closing of the collection pipe 6.

[0040] Specifically, the collection tube 6 is made of a flexible tube.

[0041] Furthermore, it also includes a drain valve, and a drain pipe 7 is provided at the drain outlet position, with the drain valve installed on the drain pipe 7.

[0042] Specifically, it also includes a filter screen 8, which is located at the outlet of the runoff collection box 4.

[0043] In this embodiment, the cross-section of the runoff collection frame 4 is preferably set as an inverted isosceles trapezoid, thereby increasing the collection volume of the runoff and also increasing the surface area of ​​the filter screen 8 at its outlet. The filter screen 8 filters the sediment carried in the surface runoff, thereby achieving effective separation of water, sediment, and fallen leaves. In addition, a collection pipe 6 is detachably installed at the water inlet. One end of the connecting pipe 9 is connected to the outlet of the runoff collection frame 4, and the other end is connected to the water inlet through the collection pipe 6. Both the collection pipe 6 and the connecting pipe 9 are made of flexible tubing, and the connecting pipe 9 has a curved and inclined structure, which facilitates the flow of water in the runoff collection frame 4 into the sample tank 2. More preferably, the upper end of the sample tank 2 is open, and the cover plate 5 is placed on the open end of the sample tank 2. An observation window is provided on the cover plate 5. Since the observation window is a transparent cover, it is convenient for the sampler to observe the collection situation in the sample tank 2. That is, the amount of sample collected can be viewed through the transparent observation window. If fine particulate matter precipitates in the water sample accumulated over a long period of time, the stirrer 51 can be used to make the sample uniformly mixed, thereby ensuring the accuracy of the sample measurement.

[0044] In this embodiment, surface runoff is collected into the runoff collection frame 4, where it is separated into mud and water by a filter screen 8. The water sample then passes sequentially through the outlet of the runoff collection frame 4, the connecting pipe 9, and the collection pipe 6 before entering the sample tank 2, where it settles. Furthermore, multiple drain outlets are provided at the bottom of the sample tank 2, each connected to a drain pipe 7. The drain pipe 7, at its end furthest from the sample tank 2, passes through a support frame and a protective box 1 before connecting to the outside, facilitating the discharge of water from the sample tank 2. If cleaning of the runoff collection device is required, water can be injected into the runoff collection frame 4 by removing the filter screen 8 and into the sample tank 2 through the sampling pipe 52. The cleaning wastewater is then discharged by opening and closing the drain valve, enabling repeated use of the collection device while preventing water sample mixing and contamination. More preferably, since the sample cell 2 is fixed in the cavity of the fixing frame 3 by screws, the sample cell 2 is fixedly installed in the receiving cavity by the fixing frame 3. At the same time, the distance between the outer wall of the sample cell 2 and the inner wall of the fixing frame 3 is greater than the distance between the outer wall of the fixing frame 3 and the inner wall of the protective box 1, thereby effectively improving the stability of the sample cell 2 installation.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
