Description

Technical Field

[0001] The utility model relates to the technical field of water quality analysis, and specifically relates to a water sample positioning and grabbing mechanism for a water quality analyzer. Background Art

[0002] With the rapid economic development of our country in recent years, the industrial and domestic waste in cities has increased significantly. At present, the main method for treating waste is sanitary landfill, and landfill operations are all carried out outdoors. After the waste is compacted, as the organisms in the waste decompose and in case of rain and snow weather, rainwater and snowmelt seep into the landfill area, generating landfill leachate. Leachate is a high-concentration organic wastewater with a large range of concentration values. It contains hydrocarbons, nitrates, sulfates and trace heavy metal ions such as copper, cadmium and lead, and the bacterial index is very high. If it is directly discharged into water bodies without treatment, it will seriously pollute the local water environment. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge.

[0003] The water quality analyzer uses the DPD method and the electrochemical method to accurately detect the residual chlorine, turbidity, pH value, conductivity, etc. of water quality. When the existing water quality detector detects a water sample, it is necessary to manually open the switch door to take and store the water sample bottle, which is inconvenient to take. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above problems, and provide a water sample positioning and grabbing mechanism for a water quality analyzer, which realizes the transfer of the water sample bottle inside and outside the water quality analyzer and is convenient to operate.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A water sample positioning and grabbing mechanism for a water quality analyzer includes a housing and a switch door arranged at the front end of the housing. A moving plate that moves back and forth inside the housing is arranged at the bottom of the housing. A positioning groove for positioning the position of the water sample bottle is arranged at the front end of the moving plate. A connecting rod is connected between the front end of the moving plate and the switch door.

[0007] Further, support blocks are symmetrically arranged at the bottom of the housing, and both ends of the moving plate are slidably connected to the support blocks.

[0008] Further, a driving mechanism for driving the moving plate to move back and forth is arranged at the bottom of the housing.

[0009] Further, the driving mechanism includes a lead screw that rotates at the bottom of the housing, and a nut that cooperates with the lead screw is arranged at the bottom of the moving plate.

[0010] Further, a handle is arranged at the rear end of the lead screw.

[0011] Further, several steps are arranged on the inner wall of the positioning groove.

[0012] Further, a connecting plate is provided on the inner side of the switch door, and the front end of the connecting rod is rotatably connected to the connecting plate.
