Description

Technical Field

[0001] This utility model relates to the field of reservoir water quality testing technology, specifically a reservoir water quality testing water sampler. Background Technology

[0002] Reservoir water quality testing is an important part of environmental protection and water resource management, and the performance of water samplers, as key tools for obtaining water samples, directly affects the accuracy of test results and sampling efficiency.

[0003] Currently, common water samplers mainly include handheld water sampling bottles and gravity samplers. These traditional water samplers have the following problems in practical use:

[0004] 1. Reliance on boats or fixed supports: Conventional water samplers require boats or fixed supports to reach sampling points far from the shore, which not only consumes a lot of manpower, time and equipment costs, but is also difficult to implement in complex waters or remote areas.

[0005] 2. Inconvenient operation: The sampling process requires the cooperation of multiple people, especially when sampling in deep water or large areas of water, which is cumbersome and inefficient.

[0006] 3. High cost: The cost of using sampling boats or building fixed supports is high, which is a heavy economic burden for units with limited budgets or frequent sampling needs.

[0007] Therefore, we propose a water sampler for reservoir water quality testing. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a water sampler for reservoir water quality testing. It utilizes the buoyancy (sponge) of the double-layered tube to make the hollow tube automatically float on the water surface, requiring only one person to operate it on the shore. The counterweight of the water intake valve makes the flexible tube automatically sink into the water for sampling, which can effectively solve the problems in the background technology.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water sampler for reservoir water quality testing, comprising a hollow tube structure, wherein the hollow tube structure is composed of at least two tube sections connected together, wherein the tube section includes a sleeve, an inner tube, a threaded groove, an externally threaded annular column and buoyancy material, wherein a water intake hose is inserted through the hollow tube structure, one end of the water intake hose is fixedly connected to a one-way water intake valve, a first lifting ring is fixedly installed on the upper part of the outer surface of one side of the one-way water intake valve, a counterweight ball is provided on one side of the one-way water intake valve, a second lifting ring is fixedly installed on the upper outer surface of the counterweight ball, and a steel wire rope is connected between the first lifting ring and the second lifting ring.

[0012] Preferably, the sleeve is fixedly installed on the outer wall of the inner tube, and the buoyancy material is filled between the inner wall of the sleeve and the outer wall of the inner tube.

[0013] Preferably, the buoyancy material is a closed-cell foam sponge.

[0014] Preferably, the threaded groove is formed on the outer surface of one end of the sleeve, and the external threaded annular post is fixedly installed on the outer surface of the other end of the sleeve.

[0015] Preferably, the inlet of the one-way water valve is located above the counterweight ball to prevent the intake of sediment.

[0016] Preferably, the tubes of the hollow tube structure are connected by threads.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a water sampler for reservoir water quality testing, which has the following beneficial effects:

[0019] 1. This reservoir water quality testing water sampler adopts a floating hollow tube design. It uses buoyancy materials (such as closed-cell foam sponge) to make the water sampler automatically float on the water surface. It does not require boats or fixed supports. Only one person needs to operate it on the shore. It can complete long-distance sampling by laying the pipe and pumping water, which greatly reduces the manpower required and improves the sampling efficiency.

[0020] 2. This reservoir water quality testing water sampler has a simple structure, mainly consisting of an assemblable hollow tube, a water intake hose, and a counterweight component. Its manufacturing cost is far lower than that of traditional sampling boats or fixed supports. The tubes are connected by threads, which makes it easy to flexibly adjust the length according to the sampling distance and adapt to the needs of different water areas.

[0021] 3. This reservoir water quality testing water sampler has a one-way water intake valve with the inlet located above the counterweight ball, ensuring that only the water sample from the target water layer is taken during sampling, effectively avoiding the intake of bottom sediments.

[0022] 4. This reservoir water quality testing water sampler features a segmented hollow tube design, which facilitates disassembly and transportation, making it suitable for use in the field or complex environments. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] This embodiment is a water sampler for reservoir water quality testing.

[0030] like Figure 1-4 As shown, it includes a hollow tube structure 1, which is composed of at least two tube sections connected together. The tube section includes a sleeve 8, an inner tube 9, a threaded groove 10, an externally threaded annular column 11, and a buoyancy material 12. A water intake hose 2 runs through the hollow tube structure 1. One end of the water intake hose 2 is fixedly connected to a one-way water intake valve 3. A first lifting ring 5 is fixedly installed on the upper part of the outer surface of one side of the one-way water intake valve 3. A counterweight ball 4 is provided on one side of the one-way water intake valve 3. A second lifting ring 6 is fixedly installed on the upper outer surface of the counterweight ball 4. A steel wire rope 7 is connected between the first lifting ring 5 and the second lifting ring 6.

[0031] The sleeve 8 is fixedly installed on the outer wall of the inner tube 9, and the buoyancy material 12 is filled between the inner wall of the sleeve 8 and the outer wall of the inner tube 9; the buoyancy material 12 is a closed-cell foam sponge; the threaded groove 10 is opened on the outer surface of one end of the sleeve 8, and the external threaded annular post 11 is fixedly installed on the outer surface of the other end of the sleeve 8; the inlet of the one-way water valve 3 is located above the counterweight ball 4 to avoid the intake of sediment; the tube bodies of the hollow tube structure 1 are connected by threads.

[0032] It should be noted that this utility model is a water sampler for reservoir water quality testing. The water intake hose 2 is passed through the foremost tube of the hollow tube structure 1. The number of tubes is selected according to the needs for assembly. During assembly, the water intake hose 2 is first passed through the tube to be assembled, and the external threaded annular post 11 in one set of tubes is threaded to the threaded groove 10 in another set of tubes. The tube is designed with a double-layer structure. The inside of the sleeve 8 is filled with buoyancy material 12, which is a closed-cell foam sponge. The buoyancy of the buoyancy material 12 in the hollow tube structure 1 must be greater than that of the tube filled with buoyancy material 12. The total weight of the water pipe, the fully loaded water intake hose 2, the one-way water intake valve 3, the counterweight ball 4, the first lifting ring 5, the second lifting ring 6, and the steel wire rope 7 is used to extend the front end of the hollow pipe structure 1 to the water intake position. The water intake hose 2 is then laid down, and the one-way water intake valve 3 is lowered by the gravity of the counterweight ball 4. One end of the water intake hose 2 is connected to a water pump for water sampling. The floating hollow pipe design eliminates the need for boats or fixed supports, allowing a single person to complete long-distance sampling on the shore. Furthermore, the model of the counterweight ball 4 can be selected according to needs to adapt to different water depth requirements.
