Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to an agricultural wastewater sampler. Background Technology

[0002] In agricultural production, the discharge of agricultural wastewater is a significant source of agricultural non-point source pollution, and its water quality directly affects the safety of the surrounding aquatic ecosystem and the quality of agricultural products. Therefore, accurate and effective sampling and monitoring of agricultural wastewater is the prerequisite and foundation for carrying out agricultural non-point source pollution prevention and control and formulating scientific treatment plans.

[0003] Currently, most commercially available agricultural wastewater sampling devices employ a single-use sampling method, meaning that wastewater is collected only once at a specific point in time using containers such as sampling bottles or buckets. This sampling method has significant limitations and shortcomings in practical applications. First, the water quality of agricultural wastewater exhibits strong dynamic changes, with pollutant concentrations fluctuating significantly due to agricultural production activities (such as irrigation, fertilization, and pesticide spraying), climatic conditions (such as rain and evaporation), and the passage of time. Therefore, it is necessary to develop an agricultural wastewater sampler capable of continuous filling and sampling. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural wastewater sampler that solves the problem of inconvenient sampling in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An agricultural wastewater sampler includes a sampling box, with multiple legs at the lower end of the sampling box and multiple cross-arranged partitions inside the sampling box, which divide the inner cavity of the sampling box into multiple sample storage slots. A detachable box cover is provided at the upper end of the sampling box, and a water intake pipe assembly for sequentially adding water to the sample storage slots is provided at the upper end of the box cover.

[0006] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the water intake pipe assembly includes a serpentine guide pipe, the water inlet end of which is provided with a water receiving box for buffering water, and the guide pipe where the water receiving box is located is provided with a flow-throttling mechanism to control the flow rate, so as to avoid excessive water volume affecting collection. The sample storage tank is located on the lower side of the guide pipe with a drain pipe, and a floating switch mechanism is provided at the location of the drain pipe.

[0007] In one alternative: the end of the guide pipe is provided with an overflow conduit for draining excess water.

[0008] In one alternative embodiment: the floating switch mechanism includes a sealing sleeve, the outer side of which is connected and fixed to the guide water pipe via a positioning vertical rod, a sealing guide rod is slidably mounted on the sealing sleeve, a floating ball is mounted at the lower end of the sealing guide rod, a sealing plate is mounted at the upper end of the floating ball, and a sealing cone is mounted at the upper end of the sealing plate.

[0009] In one alternative: the throttling mechanism includes a perforation at the upper end of the guide water pipe, an interceptor plate slidably disposed at the perforation position, a threaded block disposed on the side of the interceptor plate, an adjusting screw threaded in the threaded block, the lower end of the adjusting screw being rotatably connected to the upper end of the guide water pipe, and a wrench fixedly disposed at the upper end of the adjusting screw.

[0010] In one alternative: the upper end of the cover is provided with an installation hole corresponding to the drain pipe, and a sealing ring is provided at the location of the installation hole.

[0011] In one alternative: the sampling box is equipped with multiple water intake valves on its outer side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention addresses the shortcomings of existing single-sample water collection methods by optimizing the design to enable continuous, sequential sampling of farmland tailwater, overcoming the time limitations of traditional single-sample collection. By triggering continuous sampling at preset time intervals or flow rates, it can comprehensively capture the dynamic changes in tailwater quality across different time periods and agricultural production stages. This effectively avoids the randomness and bias of single-sample collection, making the collected water samples more continuous in time and representative overall, truly reflecting the fluctuation patterns of tailwater quality. It significantly improves the convenience and efficiency of sampling operations, reduces the labor input of frequent manual trips to sampling points, and lowers time costs and human error.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-6 As shown, this utility model embodiment provides an agricultural wastewater sampler, including a sampling box 100. The sampling box 100 has multiple support legs 102 at its lower end. The sampling box 100 has multiple cross-arranged partitions inside, which divide the inner cavity of the sampling box 100 into multiple sample storage slots 104. The multiple sample storage slots 104 are numbered sequentially from 1 to 12 along the inlet position to enable continuous sampling at one time. The sampling box 100 has a detachable box cover 101 at its upper end. The box cover 101 has a water intake pipe assembly for sequentially adding water to the sample storage slots 104. The sample storage slots 104 in the sampling box 100 can be continuously filled through the water intake pipe assembly. The water intake pipe assembly includes a serpentine guide pipe 200. The water inlet end of the guide pipe 200 is provided with a water receiving box 201 for buffering water. The guide pipe 200 where the water receiving box 201 is located is provided with a flow control mechanism 300 to control the flow rate, so as to avoid excessive water volume and affect collection. The guide pipe 200 where the sample storage tank 104 is located is provided with a drain pipe. A floating switch mechanism 400 is provided at the position of the drain pipe. When the water volume in a sample storage tank 104 reaches a predetermined amount, the corresponding floating switch mechanism 400 will close before water is poured into the next sample storage tank 104. The end of the guide water pipe 200 is provided with an overflow pipe 202 for draining excess water. When multiple sample storage tanks 104 are completely filled, the excess water can be drained along the overflow pipe 202. The floating switch mechanism 400 includes a sealing sleeve 404. The outer side of the sealing sleeve 404 is connected and fixed to the guide water pipe 200 through a positioning vertical rod 401. A sealing guide rod 405 is slidably mounted on the sealing sleeve 404. A floating ball 406 is provided at the lower end of the sealing guide rod 405. A sealing plate 403 is provided at the upper end of the floating ball 406. A sealing cone 402 is provided at the upper end of the sealing plate 403. When the water level in the sample storage tank 104 rises, the floating ball 406 will push the sealing guide rod 405 under the action of buoyancy, thereby causing the sealing plate 403 to move upward until it blocks the lower end of the drain pipe, so as to complete the sealing of the drain pipe and allow water to be injected into the next sample storage tank 104. The throttling mechanism 300 includes a perforation at the upper end of the guide water pipe 200. An interceptor plate 304 is slidably disposed at this perforation. A threaded block 301 is provided on the side of the interceptor plate 304. An adjusting screw 303 is threaded into the threaded block 301. The lower end of the adjusting screw 303 is rotatably connected to the upper end of the guide water pipe 200. A wrench 302 is fixedly disposed at the upper end of the adjusting screw 303. The wrench 302 drives the adjusting screw 303 to rotate, thus matching the adjusting screw 303 with the threaded block 301. This causes the interceptor plate 304 to slide along the perforation, adjusting the interception range of the interceptor plate 304 on the guide water pipe 200 to prevent excessive flow in the guide water pipe 200. The upper end of the box cover 101 is provided with an installation hole 103 corresponding to the drain pipe, and a sealing ring is provided at the position of the installation hole 103 to complete the assembly and docking. To facilitate water collection, the sampling box 100 is equipped with multiple water collection valves on its outer side. The water collection valves are connected to the inner cavity of the corresponding sample storage tank 104 for subsequent sampling.

[0022] Working principle: The sampling box 100 is fixed at the water receiving position, and the tailwater is received by the water receiving box 201. The wrench 302 drives the adjusting screw 303 to rotate. The adjusting screw 303 matches the threaded block 301, thereby driving the intercepting plate 304 to slide along the perforation, so as to adjust the interception range of the intercepting plate 304 on the guide water pipe 200 and avoid excessive flow in the guide water pipe 200. The tailwater will first enter the first positioning vertical rod 401. As the water level in the positioning vertical rod 401 continues to rise, when the water volume in the sample storage tank 104 rises, the floating ball 406 will exert a pushing force on the sealing guide rod 405 under the action of buoyancy, thereby causing the sealing plate 403 to move upward until it blocks the lower end of the drain pipe, so as to complete the sealing of the drain pipe and fill the next sample storage tank 104 with water. Finally, all 12 sample storage tanks 104 are completely filled, and the excess water will be discharged along the overflow pipe 202.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
