Description

Technical Field

[0001] This utility model relates to the field of water quality sampling, and in particular to a sampling device for water quality testing. Background Technology

[0002] Currently, Chinese utility model patent CN210198801U discloses a sampling device for water quality testing. Although this sampling device can prevent impurities from entering through a filter, it still has other problems during use. For example, it does not have a fixed depth and fixed point sampling function, making it difficult to control the depth of the device when it is lowered into the water flow. Moreover, the upper water will enter and mix during the descent, reducing the sampling effect. Furthermore, it does not have an adjustable support function, and the outlet of the device is positioned too low. When personnel remove the water sample, they need to lift the device so that the outlet is higher than the collection container, increasing the workload of personnel. In order to solve the above-mentioned problems, we propose a sampling device for water quality testing. Utility Model Content

[0003] The purpose of this invention is to provide a sampling device for water quality testing, which solves the problems of poor sampling effect and lack of adjustable support function of existing sampling devices.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sampling device for water quality testing, comprising a sampling cylinder, a sleeve installed on the top of the sampling cylinder, a threaded rod threadedly connected to the top of the sampling cylinder, a baffle rotatably connected to the bottom end of the threaded rod, a first opening and a second opening respectively opened on the top of the sampling cylinder and inside the baffle, a base plate provided at the bottom of the sampling cylinder, a connecting plate symmetrically installed on the top of the base plate, a lead screw symmetrically welded to the surface of the sampling cylinder, a sliding groove opened inside the connecting plate, and a nut threadedly connected to the other end of the lead screw to the outside of the sliding groove.

[0005] The above technical solution can achieve good sampling results, can perform fixed-depth and fixed-point sampling, avoid mixing with other water layers, and is highly practical. At the same time, it has an adjustable support function, is simple and convenient to operate, reduces the burden on personnel to carry for a long time, and has good flexibility.

[0006] The present invention is further configured such that: two metal filter screens are bolted to the top of the sampling cylinder, and the diameter of the metal filter screens is larger than the diameter of the first opening.

[0007] By adopting the above technical solution and setting up a metal filter screen, impurities in the water flow can be prevented from entering through the first inlet.

[0008] The present invention is further configured such that the surface of the sleeve is integrally stamped with graduation lines.

[0009] By adopting the above technical solution and setting the scale lines, it is easy for personnel to observe and understand the depth of the device's downward movement.

[0010] The present invention is further configured such that a throttle is installed at the top end of the threaded rod.

[0011] By adopting the above technical solution and by setting the throttle, it is easy for personnel to rotate the threaded rod.

[0012] The present invention is further configured such that a drain valve is connected through the surface of the sampling tube.

[0013] By adopting the above technical solution and setting up a drain valve, it is easy for personnel to discharge the water sampled inside the sampling tube.

[0014] The present invention is further configured such that a sealing gasket is installed on the top of the baffle.

[0015] By adopting the above technical solution, the sealing effect between the baffle and the first opening can be improved by setting the sealing gasket.

[0016] The present invention is further configured such that both the lead screw and the nut are made of stainless steel.

[0017] Using the above technical solution, the lead screw and nut have the characteristics of high strength, low density and excellent corrosion resistance.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model allows the sampling cylinder to be lowered to a designated depth by holding the tube sleeve with one hand, while the other hand grasps the handle and rotates it. When the handle is rotated, it will drive the threaded rod and the baffle to move downward. As the baffle moves downward, the water sample will enter the sampling cylinder from the first and second inlets. When the internal water sample is sufficient, the handle is rotated in the opposite direction to move the baffle up to the bottom. This method can achieve good sampling effect, can perform fixed-depth and fixed-point sampling, avoid other water layers from mixing in, and has high practicality.

[0020] 2. This utility model allows the nut to be loosened by hand after the device is removed. The loosened nut will cause the base plate to fall naturally. When the base plate falls, it will also move the connecting plate down. After the base plate falls to the bottom and is in contact with the ground, the nut can be tightened again. Finally, the container can be placed to one side and the drain valve can be opened. It has an adjustable support function, is simple and convenient to operate, reduces the burden of personnel carrying it for a long time, and has good flexibility. Attached Figure Description
