Description

Technical Field

[0001] The utility model relates to the technical field of wastewater detection equipment, in particular to a deep water source sampling device for wastewater detection. Background Art

[0002] Collect water samples from polluted water bodies and obtain basic data on water pollution through analysis and measurement. At present, when sampling deep water sources, a bucket-type deep water sampler is generally used. The sampling staff ties one end of the traction rope to the bucket-type deep water sampler, holds the other end, and then puts the bucket-type deep water sampler into the deep water to complete the sampling.

[0003] However, the existing bucket-type deep water sampler still has certain shortcomings when used: the bucket-type deep water sampler can only sample water sources at a certain point area in the deep water each time, and the staff needs to change different positions and repeat the above operations multiple times to complete multiple water source sampling in a certain water area. Then, after testing multiple water samples separately, the wastewater data in a certain water area can be more accurately reflected. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a deep water source sampling device for wastewater detection, which, when in use, can collect water sources at multiple locations within a certain water area at one time, making the collection of multiple water source samples more efficient and convenient.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A deep-water source sampling device for wastewater detection comprises a sampling bottle, a pressurized self-opening one-way valve, a branch traction rope and a main traction rope; a water inlet is arranged on the side of the sampling bottle, and a pressurized self-opening one-way valve is arranged on the water inlet; after the sampling bottle is submerged, the pressurized self-opening one-way valve automatically opens under the water pressure; one end of the branch traction rope is connected to the top of the sampling bottle, and the other ends of all the branch traction ropes are simultaneously tied together with one end of the main traction rope.

[0007] As an improvement, the pressurized self-opening one-way valve includes a sieve plate, a spring, a piston and a valve cylinder; the valve cylinder is threadedly sleeved on the outer wall of the water inlet, and a limit retaining ring is integrally formed on the non-connecting end toward the inside, a piston is movably provided on the inside, a water-passing gap exists between the piston and the circumferential side wall of the valve cylinder, a sieve plate is fixed on the inside of the water inlet, and the sieve plate and the piston are connected by a spring, and when the piston is pressed against the limit retaining ring, water does not enter the valve cylinder. After the sampling bottle sinks to a certain depth in the water, the pressurized self-opening one-way valve can automatically open due to a certain degree of water pressure.

[0008] As an improvement, the sampling bottle is a transparent tempered glass bottle, and a counterweight is fixed on the side wall, so that it is easier to sink into the water.

[0009] As an improvement, it also includes a main traction rope winding structure, which includes a rope winding drum and a handle; the rope winding drum is an I-shaped cylinder structure, and is rotatably sleeved on the upper part of the cylindrical handle, and the main traction rope is wound around the rope winding drum, which makes it easier to wind up the main traction rope and the traction ropes connected thereto.

[0010] The advantages of the utility model compared with the prior art are:

[0011] 1. When the present invention is in use, multiple sampling bottles are placed at different locations in a certain water area, and then after they sink into deep water, water source samples at multiple fixed locations in a certain water area can be collected at the same time, which is more efficient in collecting multiple water source samples and saves time and effort.

[0012] 2. This new design has a pressurized self-opening one-way valve, which will automatically open due to water pressure when the sampling bottle reaches the deep water position, thereby completing the collection of wastewater samples. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present utility model, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] A deep water source sampling device for wastewater detection, comprising:

[0022] The sampling bottle 1 is a transparent tempered glass bottle, with a counterweight 10 fixed on the side wall of the sampling bottle 1, a water inlet 4 provided on the other side, and a pressurized self-opening one-way valve provided on the water inlet 4. The pressurized self-opening one-way valve comprises a sieve plate 5, a spring 6, a piston 7 and a valve cylinder 8; the valve cylinder 8 is threadedly sleeved on the outer wall of the water inlet 4, and a limiting retaining ring 9 is integrally formed on the non-connecting end facing inward, a piston 7 is movably provided on the inner side, and a water-passing gap is provided between the piston 7 and the circumferential side wall of the valve cylinder 8, a sieve plate 5 is fixed on the inner side of the water inlet 4, and the sieve plate 5 and the piston 7 are connected by a spring 6, and after the piston 7 is pressed against the limiting retaining ring 9, water does not enter the valve cylinder 8;

[0023] The branch traction rope 2, the main traction rope 3 and the main traction rope winding structure; one end of the branch traction rope 2 is tied to the rope binding ring 11 formed integrally on the top of the sampling bottle 1, and the other ends of all the branch traction ropes 2 are tied together with one end of the main traction rope 3. The main traction rope winding structure includes a rope drum 12 and a handle 13; the rope drum 12 is an I-shaped cylindrical structure, and is rotatably sleeved on the upper part of the cylindrical handle 13, and the main traction rope 3 is wound on the rope drum 12.

[0024] During the specific implementation of this embodiment: two staff members, one holds two sampling bottles 1, and the other holds a sampling bottle 1 in one hand and holds the handle 13 in the other hand, and then the two staff members throw three sampling bottles 1 to different places of the wastewater at the same time. During the sinking process of the sampling bottle 1, the main traction rope 3 and the main traction rope slowly sink into the water, and after sinking to a certain depth, they reach the deep water area. At this time, the water pressure on the piston 7 is greater than the elastic squeezing force of the spring 6, and the piston 7 will open, and the water source sample enters the sampling bottle 1 until the sampling is completed. During this process, the sampling bottle 1 is always in a vertical sinking state. Finally, when the length of the main traction rope 3 is released to the point where it can no longer be released, the main traction rope 3 and the branch traction rope 2 can be rolled up on the rope drum 12 in turn, and then each sampling bottle 1 is taken out and taken back to implement wastewater detection.

[0025] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
