Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a water quality detection sampling device. Background Art

[0002] Water quality testing includes testing of sewage, pure water, seawater, fishery water, irrigation water, landscape water, drinking water, groundwater, surface water of rivers, lakes, etc. In environmental monitoring, the quality of surface water of rivers, lakes, etc. is often used to judge the local environmental conditions. Water sampling devices are used to sample water bodies, and then experimental equipment is used to test water quality.

[0003] Currently, the commonly used surface water detection sampling device includes a water sampling cylinder, which is suspended by a rope and placed in the water. Water enters the water sampling cylinder from the water inlet hole at the bottom of the water sampling cylinder. When the water sampling cylinder is lifted up, the flap on the top of the water sampling cylinder and the bottom cover of the water inlet hole automatically close down, and water samples can be obtained from the water body.

[0004] However, in many natural waters, due to lack of management, the water bodies are often mixed with large suspended matter such as floating aquatic plants and garbage, which can easily block the water inflow and affect water intake. When taking out the water collection tube from the water body, the large suspended matter can easily block the bottom cover of the water inlet hole and cause water leakage. After entering the water collection tube, the large suspended matter can easily block the thinner drain pipe, making it inconvenient to discharge the water sample from the drain pipe, which brings many inconveniences to use. Therefore, a new type of water quality detection sampling device is designed and proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a water quality detection sampling device, including a water collection tube 1, the water collection tube 1 includes a flip cover 11 and a handle 12 arranged on the top, a water inlet hole 13 arranged at the bottom of the water collection tube 1, a bottom cover 14 arranged at the bottom of the inner wall of the water collection tube 1 corresponding to the water inlet hole 13, and a water discharge pipe 15 arranged at the outer wall of the water collection tube 1 near the bottom;

[0022] The outer wall bottom of the water intake cylinder 1 is threadedly sleeved with a threaded connecting pipe 2, and the threaded connecting pipe 2 is used for detachably installing a filter cartridge 3. The water intake cylinder 1 is movably connected with a filter cartridge 3 with an open top and filtering on the side surface through the threaded connecting pipe 2. The height of the filter cartridge 3 is not less than the height of the water intake cylinder 1, and the outer diameter of the filter cartridge 3 is not less than the outer diameter of the water intake cylinder 1. A filter screen 4 corresponding to the side surface position is movably installed on the filter cartridge 3. The filter screen 4 includes different mesh sizes and can be replaced and used to intercept suspended matter of different sizes;

[0023] A water inlet groove 31 is provided on the circumferential side wall of the filter cartridge 3, and the filter screen 4 is cylindrical. The filter screen 4 is movably sleeved on the surface of the filter cartridge 3, and a stop convex block 32 corresponding to the top of the filter cartridge 3 is provided at a position near the top of the outer wall of the filter cartridge 3 to limit the installation position of the filter screen 4;

[0024] A vertical threaded column 5 is fixedly connected to the bottom of the filter cartridge 3, and a counterweight 6 supported at the bottom of the filter screen 4 is movably connected to the filter cartridge 3 through the threaded column 5. Anti-slip grooves 7 are provided on the circumferential side walls of the threaded connecting tube 2 and the counterweight 6, which are convenient for twisting and disassembling to facilitate cleaning after use. The counterweight 6 is in a cone shape with the bottom protruding downward. The length of the threaded column 5 is not less than the height of the counterweight 6, which is convenient for draining water. The counterweight 6 facilitates the sinking of the water extraction cartridge 1 in the water.

[0025] Working principle: The filter cartridge 3 is threadedly connected to the bottom of the water collection cylinder 1 through the threaded connection pipe 2. A filter screen 4 with a suitable mesh size is selected and placed on the surface of the filter cartridge 3. The counterweight block 6 is screwed to fix the filter screen 4. A water stop clamp is clamped on the drain pipe 15. A rope is hung on the handle 12. The water collection cylinder 1 is vertically placed in the water.

[0026] The water collection cylinder 1 sinks, and the water is simply filtered through the filter screen 4 and enters the filter cylinder 3 and flows upward to push open the bottom cover 14 of the water inlet hole 13 to enter the water collection cylinder 1. At the same time, the air in the water collection cylinder 1 flows upward to push open the flip cover 11 to be discharged. The water collection cylinder 1 is pulled upward by the rope, and the flip cover 11 flips downward to cover due to the resistance of the water, and at the same time, the bottom cover 14 is pushed to cover the water inlet hole 13. The water collection cylinder 1 is taken out from the water body to complete the sampling of the water body. Finally, the water sample is discharged into the water sample collection bag through the drain pipe 15;

[0027] The filter 4 can selectively obtain suspended matter of a certain size in the water body when taking water, and at the same time can block larger suspended matter in the water body, preventing the larger suspended matter from affecting the water intake of the water intake tube 1, the closing of the bottom cover 14 and the drainage of the drain pipe 15, which is more convenient to use.
