Description

Technical Field

[0001] This utility model belongs to the field of water quality testing technology, specifically relating to a sampling device for water quality testing in rice cultivation. Background Technology

[0002] In rice cultivation, water quality directly affects the growth of rice and its final yield. Therefore, it is crucial to accurately control the quality of water used for rice cultivation, which requires scientific and effective sampling and testing of water bodies.

[0003] Typically, rice paddies are relatively shallow, and in practice, people often use simple tools like buckets to scoop water from the edge of the paddy. However, this traditional method has significant drawbacks. First, due to limitations in tools and operation, it's difficult to collect water samples from areas further from the paddy edge, resulting in a lack of comprehensiveness and an inability to accurately reflect the water quality of the entire paddy. Second, the long-distance sampling devices commonly used in agricultural production often employ a top-entry design, which is extremely inconvenient in shallow water conditions like rice paddies, significantly increasing the difficulty of water collection. Even more problematic is that neither traditional bucket scooping nor existing long-distance sampling devices can effectively filter impurities from the water sample. Large particles of silt, floating debris, and other impurities easily mix into the sample, severely impacting the accuracy of subsequent water quality testing and causing deviations in the results, thus failing to provide reliable water quality data for rice cultivation. Utility Model Content

[0004] The purpose of this invention is to provide a convenient sampling device for testing water quality in rice cultivation in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A sampling device for water quality testing in rice cultivation includes a telescopic rod and a steel wire rope mounted on the telescopic rod, and further includes:

[0007] A sample inlet container, which is attached to the end of a telescopic rod by a steel wire rope;

[0008] A sample storage tank is movably connected to a sample inlet tank, through which water samples enter the sample storage tank.

[0009] A floating plate is slidably disposed in the sample injection tank and is movably connected to the sample injection tank.

[0010] As a further optimization of this utility model, a counterweight frame is provided at the lower end of the sample injection barrel, a filter screen is provided on the counterweight frame, a sliding groove is provided inside the sample injection barrel, and the floating plate is slidably disposed in the sample injection barrel through the sliding groove.

[0011] As a further optimization of this utility model, the lower end of the sample storage barrel is provided with a thread, the upper surface of the counterweight frame is provided with a fixing groove, and the sample storage barrel is connected to the fixing groove through the thread.

[0012] As a further optimization of this utility model, the floating plate is provided with a plurality of protrusions, which can be embedded in the sliding groove. The lower surface of the floating plate is provided with a cover plate, which can be embedded in the sample storage barrel. A plurality of floats are arranged in an array around the cover plate.

[0013] As a further optimization of this utility model, a base is provided on the telescopic rod, a rotating handle is rotatably provided on the base, and a winding wheel is provided on the base through the rotating handle.

[0014] As a further optimization of this utility model, one end of the wire rope is wound around the winding wheel, and the telescopic rod is provided with multiple limiting rings, through which the wire rope passes.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Unlike existing technologies, in actual use, the counterweight frame at the bottom of the sample inlet tank, combined with a filter screen, ensures that the device is placed stably in the water, while the filter screen effectively filters out large particulate impurities in the water, ensuring that the water sample entering the sample storage tank is relatively pure, laying the foundation for subsequent accurate detection.

[0017] 2. Unlike existing technologies, in actual use, the floating plate that is slidably connected inside the sample container has floats around the cover plate on its lower surface, which allows the floating plate to rise and fall with the water surface. After sampling, the sample storage container is sealed by the cover plate to prevent water sample spillage. Attached Figure Description

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 - Figure 5 As shown, a sampling device for water quality testing in rice cultivation includes a telescopic rod 1 and a steel wire rope 2 mounted on the telescopic rod 1, and also includes:

[0027] The sample inlet 3 is attached to the end of the telescopic rod 1 via a steel wire rope 2.

[0028] The sample storage tank 5 is movably connected to the sample inlet tank 3, and the water sample enters the sample storage tank 5 through the sample inlet tank 3;

[0029] The floating plate 6 is slidably disposed in the sample injection tank 3 and is movably connected to the sample injection tank 3.

[0030] A counterweight frame 31 is provided at the lower end of the sample inlet tank 3. The counterweight frame 31 can keep the sample inlet tank 3 stable in the water and prevent it from shaking due to external factors such as water flow and wind. A filter screen 32 is provided on the counterweight frame 31, which can perform preliminary filtration of the water sample entering the sample inlet tank 3, blocking large particles of mud, sand, floating objects and other impurities, preventing them from entering the sample storage tank 5, and ensuring the accuracy of subsequent water quality testing. A sliding groove 33 is provided inside the sample inlet tank 3. The float plate 6 is slidably set in the sample inlet tank 3 through the sliding groove 33, providing a track for the sliding of the float plate 6, so that the float plate 6 can move smoothly according to the rise and fall of the water surface.

[0031] The lower end of the sample storage container 5 is provided with a thread 51, and the upper surface of the counterweight frame 31 is provided with a fixing groove 52. The sample storage container 5 is connected to the fixing groove 52 through the thread 51. This connection method is not only stable and can reduce shaking in the water, but also easy to install and disassemble, making it convenient to take out the sample storage container 5 for water quality testing later.

[0032] The floating plate 6 is provided with multiple protrusions 61, which can be embedded in the sliding groove 33 to ensure that the floating plate 6 is stable in direction when sliding in the sample inlet 3 and will not deviate or get stuck. The lower surface of the floating plate 6 is provided with a cover plate 63, which can be embedded in the sample storage 5. During sampling, the cover plate 63 floats up under the buoyancy of the float 62, and the water sample enters the sample storage 5 smoothly. After sampling, the cover plate 63 falls back to seal the sample storage 5 to prevent water sample from spilling. Multiple floats 62 are arrayed around the cover plate 63.

[0033] A base 41 is provided on the telescopic rod 1, and a rotating handle 42 is rotatably provided on the base 41. A winding wheel 4 is provided on the base 41 through the rotating handle 42. The winding operation of the wire rope 2 is realized by rotating the rotating handle 42, thereby controlling the lifting and lowering of the sample inlet bucket 3.

[0034] One end of the wire rope 2 is wound around the winding wheel 4, and multiple limit rings are provided on the telescopic rod 1, through which the wire rope 2 passes.

[0035] It should be noted that when this rice cultivation water quality testing and sampling device is working, firstly, the telescopic rod 1 serves as a support and length adjustment mechanism. Its end is connected to the sample inlet barrel 3 via a steel wire rope 2. The counterweight frame 31 at the lower end of the sample inlet barrel 3 ensures the stability of the device in the water. The filter screen 32 on the counterweight frame 31 can initially filter impurities in the water to prevent large particles from entering. A sliding groove 33 is provided inside the sample inlet barrel 3, and the float plate 6 is slidably connected to it through the sliding groove 33. The protrusions 61 on the float plate 6 ensure smooth sliding within the sliding groove 33. Multiple floats 62 are arrayed around the cover plate 63 on its lower surface. The buoyancy allows the float plate 6 to rise and fall with the water surface, and the cover plate 63 can be embedded in the storage tank. The sample tank 5 and the storage tank 5 are movably connected to the sample inlet tank 3. The thread 51 at the lower end of the storage tank 5 can be tightly connected to the fixing groove 52 on the upper surface of the counterweight frame 31 to ensure the stability of the storage tank 5. When the device is placed in water, water will enter the storage tank 5 through the sample inlet tank 3. At this time, the cover plate 63 of the float plate 6 floats up under the action of buoyancy, and the water sample smoothly enters the storage tank 5. After sampling is completed, the rotating handle 42 at the base 41 of the telescopic rod 1 can be rotated to drive the winding wheel 4, so that the sample inlet tank 3 rises and the float plate 6 falls back. The cover plate 63 seals the storage tank 5 to prevent water sample from spilling, thereby realizing the recovery of the device. The storage tank 5 with collected water sample can be taken out for subsequent water quality testing.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
