Description

Technical Field

[0001] This application relates to the technical field of water quality detection and sampling for algae-infested water layers, and in particular to a sampling device for detecting the water quality of algae-infested water layers. Background Technology

[0002] Phytoplankton is an ecological concept that refers to tiny plants that live in water by floating. Phytoplankton usually refers to planktonic algae, including eight phyla: cyanobacteria, green algae, diatoms, golden algae, yellow algae, dinoflagellates, cryptophytes, and euglenoids.

[0003] Due to environmental pollution, the eutrophication of some lakes is constantly worsening, leading to a rapid increase in algae in the water. The presence of large amounts of algae directly affects the production and supply of tap water. In order to understand the impact of algae on various processes in water treatment plants, many water plants that use lake water as their source have successively launched algae counting and testing projects.

[0004] When sampling for testing, it is necessary to sample the upper layer of floating algae and the lower layer of water separately. In the existing technology, the general method is to let it stand in a container. After standing, the upper layer of liquid is extracted with a syringe as the floating algae sample and the lower layer of water is used as the water sample.

[0005] However, in actual use, because the upper layer of floating algae is relatively thin, the syringe can easily draw water from the lower layer, thus affecting the test results. Therefore, there is an urgent need to develop a sampling device with good stratification effect and more accurate sampling. Utility Model Content

[0006] The purpose of this application is to provide a sampling device for detecting the water quality of algae-bearing water layers, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this application provides a sampling device for detecting the water quality of algae-covered water layers, employing the following technical solution:

[0008] A sampling device for detecting algae in a water layer includes a base, a settling cylinder, a piston, a driving lifting mechanism, and a cover. The settling cylinder is a cylindrical body open at both ends. A bracket is fixed on the base, and the settling cylinder is detachably fixed on the bracket. The piston is movably disposed inside the settling cylinder. The driving lifting mechanism is mounted on the base and is used to drive the piston to move up and down. The cover is detachably connected to the top of the settling cylinder. The cover includes a connecting section and a thin cylindrical section. The connecting section is threaded onto the settling cylinder. One end of the thin cylindrical section is connected to the middle of the connecting section. An outlet pipe is inclinedly disposed on the side of the thin cylindrical section, and a sampling tube is sleeved on the outlet pipe.

[0009] The drive lifting mechanism includes a bidirectional slide ball screw module. Connecting rods are respectively hinged to the two slides of the bidirectional slide ball screw module. A lifting block is hinged to one end of each connecting rod. The piston is detachably fixed to the lifting block by screws.

[0010] A hand crank is fixed to one end of the ball screw module of the bidirectional slide table.

[0011] Preferably, for ease of cleaning, the piston has an annular sealing groove on its ring side, and a sealing ring is provided in the annular sealing groove.

[0012] Preferably, for ease of observation, the cover is made of transparent tempered glass.

[0013] Preferably, in order to facilitate use and avoid the influence of bacteria on algae, the sampling tube is a disposable sampling tube.

[0014] In summary, this application includes at least one of the following beneficial technical effects: the sampling device for detecting algae in the water layer is equipped with a settling cylinder, a piston, a drive lifting mechanism, and a cover. The cover has a thin cylindrical section. The drive lifting mechanism drives the piston to push the solution in the settling cylinder upward. The algae floating on the surface of the water are squeezed into the cover and move upward along the thin cylindrical section. Then, they enter the sampling tube through the liquid outlet pipe, thus completing the sampling of algae. The sampling results are relatively accurate. Attached Figure Description

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0019] This application discloses a sampling device for detecting the water quality of algae-covered water layers, referring to... Figure 1-2The device includes a sampling apparatus for detecting algae in the water layer, comprising a base 1, a settling cylinder 2, a piston 3, a drive lifting mechanism 4, and a cover 5. The settling cylinder 2 is a cylinder with openings at both ends. A bracket 11 is fixed on the base 1, and the settling cylinder 2 is detachably fixed on the bracket 11. The piston 3 is movably disposed inside the settling cylinder 2. The drive lifting mechanism 4 is mounted on the base 1 and is used to drive the piston 3 to move up and down. The cover 5 is detachably connected to the top of the settling cylinder 2. The cover 5 includes a connecting section 51 and a thin cylindrical section 52. The connecting section 51 is threaded onto the settling cylinder 2. One end of the thin cylindrical section 52 is connected to the middle of the connecting section 51. An outlet pipe 53 is inclinedly arranged on the side of the thin cylindrical section 52. A sampling tube 6 is sleeved on the outlet pipe 53. The sampling tube 6 is a disposable sampling tube. The cover 5 is made of transparent tempered glass.

[0020] Reference Figure 2 The driving lifting mechanism 4 includes a bidirectional slide ball screw module 41. Connecting rods 42 are respectively hinged on the two slides of the bidirectional slide ball screw module 41. A lifting block 43 is hinged to one end of the connecting rod 42. The piston 3 is detachably fixed to the lifting block 43 by screws. A hand crank is fixed to one end of the screw of the bidirectional slide ball screw module 41.

[0021] By using a hand crank to drive the bidirectional slide ball screw module 41, the hand crank allows the sampling personnel to easily push the piston 3 upward as needed, resulting in relatively precise control.

[0022] Reference Figure 2 To facilitate cleaning, an annular sealing groove 31 is provided on the ring side of the piston 3, and a sealing ring 32 is provided in the annular sealing groove 31. After sampling, the sealing ring 32 can be removed from the annular sealing groove 31, and the annular sealing groove 31 and the sealing ring 32 can be thoroughly cleaned to avoid affecting subsequent use.

[0023] The implementation principle of the sampling device for detecting the water quality of algae layer in this application embodiment is as follows:

[0024] The sampling personnel directly poured the collected algae-laden water into the settling cylinder 2 for settling. After a period of settling, the cover 5 was screwed onto the settling cylinder 2. The bidirectional sliding table ball screw module 41 was driven by the hand crank. The two sides of the bidirectional sliding table ball screw module 41 moved towards the middle at the same time, which pushed the lifting block 43 upward through the connecting rod 42. The lifting block 43 pushed the piston 3 upward, and the piston 3 pushed the liquid in the settling cylinder 2 upward. During the upward movement, the algae floating on the surface of the water were squeezed into the cover 5 and moved upward along the thin cylinder section 52. Then, it entered the sampling tube 6 through the liquid outlet pipe 53, thus completing the sampling of algae. The sampling results were relatively accurate.

[0025] After the algae sampling is completed, continue to push the piston 3 upwards to empty the algae, then drain some water, and finally remove the cover 5 to sample the remaining water in the settling cylinder 2.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
