Description

Technical Field

[0001] This utility model relates to the field of water quality testing technology, specifically to an environmental protection testing device that is easy to disassemble and install. Background Technology

[0002] Water is the source of life, and humans cannot live or produce without it. The quality of drinking water is closely related to human health. With socio-economic development, scientific progress, and the improvement of people's living standards, people's requirements for drinking water quality are constantly increasing, and drinking water quality standards are also constantly developing and improving accordingly.

[0003] A search revealed a patent document with publication number CN218600950U, which discloses an environmental protection testing device. The device includes a testing box with a sliding handle on one side. A test tube is located inside the side of the handle. A collection mechanism is fixedly installed inside the testing box, and a lifting mechanism is rotatably mounted on one side of the handle. The collection mechanism includes an air intake chamber at the top of the testing box, with a piston slidingly mounted on its inner wall. The piston, near the handle, penetrates the inner wall of the testing box, and the portion extending out of the box is fixedly mounted on the top of the handle. This application, by incorporating the collection and lifting mechanisms, allows for long-distance water sampling via a suction pipe, thus preventing accidental water falls when personnel bend down to collect samples.

[0004] The aforementioned patent also has the following drawbacks: For example, the sampling water level cannot be observed because the test tube is installed inside the pull handle and pushed into the testing box along with the handle. During sampling, the test tube is completely inside the testing box's internal cavity, while the outer shell of the testing box, usually metal or plastic, obstructs the view. The operator cannot know when the test tube is full, leading to water sample overflowing from the test tube, contaminating the inside of the testing box, requiring cleaning, wasting sample, and potentially damaging the equipment. Therefore, an environmentally friendly testing device that is easy to disassemble and install is proposed to solve the problems mentioned above. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 4 This embodiment provides an environmental protection testing device that is easy to disassemble and install. It includes a housing 1 and a test tube 5. The housing 1 is equipped with an environmental protection sampling structure 2, which consists of a check valve 21 and a piston 22. Specifically, the check valve 21 includes a valve pipe 211, inside which are two symmetrically distributed valves 212. The piston 22 includes a piston cylinder 221, inside which a piston block 222 slides against the piston. A connecting rod 223 extending to the outside of the piston cylinder 221 is fixed to the upper surface of the piston block 222. It should be noted that a bracket can also be bolted to the bottom side of the housing 1.

[0027] To facilitate the assembly and disassembly of the check valve 21 and the piston 22, a mounting groove 11 is provided inside the housing 1. The mounting groove 11 is T-shaped, with one protruding side communicating with the upper surface of the housing 1, and both ends communicating with the left and right sides of the housing 1. Mounting brackets 12 are fixed to the inner sides of both ends of the mounting groove 11. The valve pipe 211 is detachably mounted between the two mounting brackets 12. The bottom end of the piston cylinder 221 extends into the mounting groove 11, communicating with both the piston cylinder 221 and the valve pipe 211. The bottom end of the piston cylinder 221 is threadedly connected to the inside of the valve pipe 211. The T-shaped structure of the mounting groove 11 allows the valve pipe 211 and piston cylinder 221 to be directly inserted into or removed from the top or sides of the housing 1 without disassembling other components. This design significantly shortens the time for equipment commissioning or component replacement, improving on-site operational efficiency.

[0028] In addition, valve tube 211 is fixed by mounting bracket 12 and can be replaced independently of piston cylinder 221. If check valve 21 malfunctions or needs to be upgraded, only valve tube 211 needs to be removed without affecting piston cylinder 22, reducing maintenance costs.

[0029] To enable the check valve 21 to work in conjunction with the piston 22, a through hole 213 communicating with the piston cylinder 221 is provided inside the valve tube 211, and a sampling tube 4 is fixed to one end of the valve tube 211. Two valves 212 are elastically hinged inside the valve tube 211, and a return spring 224 fixed to the top side of the piston cylinder 221 is wound around the outside of the connecting rod 223. The return spring 224 automatically pushes the piston block 222 back to its original position after the piston block 222 moves upward, eliminating the need for manual pressing and simplifying the operation process.

[0030] To facilitate the operation of the piston 22, two symmetrically distributed handles 225 are fixed to the outer surface of the top end of the connecting rod 223. Anti-slip sleeves are fitted onto the outer surface of each handle 225. The two symmetrically distributed handles 225 conform to ergonomic principles, allowing the operator to apply force with both hands simultaneously to quickly pull the piston cylinder 221, reducing fatigue during single-handed operation. An annular pad is fixed to the outer surface of the piston cylinder 221, abutting against the top side of the housing 1, and a positioning hole is provided inside the annular pad. Two limiting blocks are provided inside the valve tube 211 for limiting the movement of the valve 212.

[0031] To facilitate the rapid assembly and disassembly of test tube 5, a docking assembly 3 is provided on the housing 1, which connects to the sampling structure 2 and is used for installing test tube 5. The docking assembly 3 consists of a connecting pipe 31 and an elastic telescopic rod 33. The top end of the connecting pipe 31 is connected to the flange at the other end of the valve pipe 211. Specifically, test tube 5 is detachably installed between the elastic telescopic rod 33 and the connecting pipe 31. A mounting platform 32 is fixed on the side wall of the housing 1, and the elastic telescopic rod 33 is fixed on the mounting platform 32. The bottom end of test tube 5 is connected to the top end of the elastic telescopic rod 33, and the deformation of the elastic telescopic rod 33 connects the top end of test tube 5 to the end of the connecting pipe 31. Sealing rings 34 are provided on the outer surfaces of both the connecting pipe 31 and the test tube 5. The elastic telescopic rod 33 consists of a telescopic rod and a spring, with the spring located inside the telescopic rod. An anti-slip pad is fixed to the top end of the telescopic rod. During use, the operator simply presses the bottom of test tube 5 against the top of the elastic telescopic rod 33. The reverse elastic force generated by the elastic deformation automatically seals the top of test tube 5 against the end of the connecting tube 31. The assembly and disassembly process takes only a few seconds, offering the advantage of easy assembly and disassembly. A locking function can also be installed on the outside of the telescopic rod. After test tube 5 is installed, the locking function can lock the extension and retraction of the telescopic rod, effectively preventing test tube 5 from accidentally falling off due to vibration or external force.

[0032] The working principle of the above embodiments is as follows:

[0033] Two symmetrically hinged valves 212 within valve tube 211 form a unidirectional flow channel. When a negative pressure is generated within piston cylinder 221, external liquid enters valve tube 211 through sampling tube 4, pushing open valve 212 and entering piston cylinder 221; when the flow is reversed, valve 212 closes to prevent backflow of liquid, and handle 225 pulls connecting rod 223, causing piston block 222 to move upward within piston cylinder 221, creating negative pressure to draw in liquid; after release, return spring 224 pushes piston block 222 downward, pushing liquid into docking assembly 3;

[0034] The bottom of the test tube 5 is connected to the top of the elastic telescopic rod 33. The elastic telescopic rod 33 deforms under pressure and generates a reverse elastic force, so that the top of the test tube 5 is tightly fitted with the end of the connecting tube 31. With the help of the sealing ring 34, a leak-free connection is achieved. The liquid flows from the piston cylinder 221 through the valve tube 211 into the connecting tube 31, and finally enters the test tube 5 to complete the sampling and storage, realizing environmentally friendly sampling and testing.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
