Description

Technical Field

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

[0002] Water quality is a shorthand for the quality of water bodies. It refers to the physical (such as color, turbidity, odor, etc.), chemical (content of inorganic and organic matter), and biological (bacteria, microorganisms, plankton, benthic organisms) characteristics and composition of water bodies. To evaluate the quality of water bodies, a series of water quality parameters and standards are defined. These include water quality standards for drinking water, industrial water, and fishery water.

[0003] The existing sampling method involves using water quality sampling devices to sample water. These devices typically use water pumps to sample the water. However, during the sampling process, staff usually manually place the container at the bottom of the outlet. In this process, the container may tip over, causing the water sample to spill out, which necessitates resampling. This significantly reduces the efficiency of water sampling. Furthermore, the water sample pumped up contains impurities, which can affect the results of water quality testing.

[0004] Therefore, given the potential for tipping over of existing containers and the presence of impurities in the water, a fully automated sampling device is needed to address these issues. Utility Model Content

[0005] To address the issues of potential tipping of the container and impurities in the water in existing technologies, this application provides a fully automated sampling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fully automatic sampling device includes a housing. An electric slide rail is fixedly connected to the inner wall of the bottom end of the housing. A movable frame is slidably connected to the top end of the electric slide rail. A transmission assembly is provided on the right side of the movable frame. A limit rod is fixedly connected to the top end of the movable frame. A bidirectional lead screw is provided at the rear end of the limit rod. The bidirectional lead screw is rotatably connected to the movable frame. A clamping block one and a clamping block two are threadedly connected to the outer wall of the bidirectional lead screw. A fixing plate is fixedly connected to the inner wall of the rear end of the housing. A slider is provided at the bottom end of the fixing plate. Limit blocks are fixedly connected to both ends of the slider. A limit frame is slidably connected to the opposite side of the two limit blocks. The limit frame is fixedly connected to the bottom end of the fixing plate. A filter assembly is provided at the center of the top end of the slider.

[0008] As a further improvement of this utility model, the transmission assembly includes two pulleys connected by a belt at the right end of the movable frame. The top pulley is fixedly connected to the right end of the bidirectional lead screw, and a motor is provided at the left end of the bottom pulley. The driving end of the motor is connected to the bottom pulley, and the non-driving end of the motor is connected to the movable frame.

[0009] As a further improvement of this utility model, the filter assembly includes a funnel groove located at the center of the top of the slider, a protrusion is fixedly connected to the inner wall of the funnel groove, a limiting post is fixedly connected to the top of the protrusion, and a filter plate is provided at the top of the limiting post.

[0010] As a further improvement of this utility model, a pump body is installed at the top of the fixed plate, and a hose is fixedly connected to the input end of the pump body, with the hose at the output end located at the middle of the top of the slider.

[0011] As a further improvement of this utility model, a control console is fixedly connected to the top of the housing, and a revolving door is rotatably connected to the front end of the housing.

[0012] As a further improvement of this utility model, an electric telescopic rod is fixedly connected to the inner wall of the top of the shell, a cup lid is provided at the bottom of the electric telescopic rod, and a cup is provided at the bottom of the cup lid.

[0013] As a further improvement of this utility model, the bottom end of the housing is fixedly connected with a support foot.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, the motor drives the pulley to rotate, which in turn drives the bidirectional lead screw to rotate. This causes clamping blocks one and two to clamp the cup, ensuring that the cup remains stable and does not shake during the entire sampling process. This greatly reduces sampling errors caused by container displacement. Furthermore, the equipped hoses are of different lengths, which, combined with the pump, enable the collection of water samples at different depths. This significantly improves the targeting and comprehensiveness of the sampling, providing a reliable sample basis for subsequent water quality analysis.

[0016] 2. In this utility model, the sliding rail combined with the moving frame design can automatically move the holding cup to the bottom of the slider, so that the holding cup can receive the sample, reducing the tediousness and time cost of manual operation. When it is necessary to clean and maintain the filter plate, simply lift the filter plate from the top of the protrusion and let it get away from the limiting post to complete the disassembly. The disassembly process is simple and quick, which makes it convenient for staff to replace and maintain the filter plate, and improves the efficiency of filter plate replacement and maintenance.

[0032] Example 1:

[0033] An automated sampling device includes a housing 1. An electric slide rail 12 is fixedly connected to the inner wall of the bottom end of the housing 1. A movable frame 5 is slidably connected to the top end of the electric slide rail 12, allowing the movable frame 5 to move via the electric slide rail 12. Two pulleys 11 connected by belts are arranged on the right side of the movable frame 5. The top pulley 11 is fixedly connected to the right end of a bidirectional lead screw 19, enabling the top pulley 11 to rotate. A motor 10 is arranged on the left end of the bottom pulley 11, driving the bottom pulley 11 to rotate. The driving end of the motor 10 is connected to the bottom pulley 11, and the non-driving end of the motor 10 is connected to the movable frame 5. A limit rod 6 is fixedly connected to the top end of the movable frame 5, limiting the movement of clamping blocks 16 and 17. A bidirectional lead screw 19 is arranged at the rear end of the limit rod 6, rotatably connected to the movable frame 5. The outer wall of the bidirectional lead screw 19 is threaded with clamping block 16 and clamping block 27. The top of clamping block 16 and clamping block 27 is equipped with a detection device 25. The detection device 25 can detect the water in the container 8. When the water level reaches a certain amount, the detection device 25 sends a stop signal to the pump body 15, thereby stopping the pump body 15 from working, which improves the efficiency of water sampling and reduces labor costs. By rotating the bidirectional lead screw 19, clamping block 16 and clamping block 27 on its outer wall can move, thereby clamping and limiting the container 8. The inner wall of the rear end of the housing 1 is fixedly connected with a fixing plate 7. The bottom end of the fixing plate 7 is equipped with a slider 13. Limiting blocks 20 are fixedly connected to both ends of the slider 13. The limiting blocks 20 can limit the slider 13. The two limiting blocks 20 are slidably connected to the opposite side of the two limiting blocks 20. The limiting frame 14 is fixedly connected to the bottom end of the fixing plate 7.

[0034] Example 2:

[0035] As one of the optimized structural designs for Example 1, such as Figures 1-7As shown, a funnel groove 22 is opened at the top center of the slider 13. Water pumped up by the pump body 15 flows into the holding cup 8 through the funnel groove 22. A protrusion 23 is fixedly connected to the inner wall of the funnel groove 22. A limiting post 24 is fixedly connected to the top of the protrusion 23. The limiting post 24 can limit the filter plate 21, which can be disassembled for maintenance and replacement. The filter plate 21 is set at the top of the limiting post 24. The filter plate 21 can be used to limit the water pumped by the pump body 15. The pumped water is filtered to prevent impurities from flowing into the holding cup 8. A pump body 15 is installed at the top of the fixed plate 7. The pump body 15 has a hose 9 fixedly connected to its input end. The hoses 9 have different lengths and can automatically sample water from different layers through the hoses 9 and the pump body 15. The output hose 9 is located at the top center of the slider 13. The water pumped by the pump body 15 flows into the funnel groove 22 through the output hose 9, and then flows into the holding cup 8. A control console 2 is fixedly connected to the top of the housing 1, and a rotating door 3 is rotatably connected to the front end of the housing 1. An electric telescopic rod 4 is fixedly connected to the inner wall of the top of the housing 1. A cup lid 18 is provided at the bottom of the electric telescopic rod 4. The electric telescopic rod 4 can push the cup lid 18 to move, thereby covering the container cup 8 with the cup lid 18, thus protecting the sample in the container cup 8, preventing impurities from entering the container cup 8, and also preventing splashing out of the container cup 8. The container cup 8 is provided at the bottom of the cup lid 18, and the container cup 8 can store the water pumped up by the pump body 15. A support foot is fixedly connected to the bottom of the housing 1.

[0036] Working principle: First, the container 8 is placed between clamping blocks 16 and 17. The motor 10 drives the bottom pulley 11 to rotate, which in turn drives the top pulley 11 to rotate via a belt. The top pulley 11 then drives the double-acting screw 19 to rotate, thereby clamping and limiting the container 8 with clamping blocks 16 and 17 to ensure its stability. Then, the hose 9 is placed in the water. Since the hose 9 has different lengths, the pump body 15 can sample water from different layers. The sliding rail 12 moves the moving frame 5 to the fixed plate 7. The bottom of the slide 13 is moved so that the moving frame 5, carrying the container cup 8, moves to the bottom of the slider 13. The water pumped up by the pump body 15 flows into the container cup 8 through the filter plate 21. After the sampling is completed, the moving frame 5 is moved to the bottom of the cup lid 18 through the slide rail 12. Then, the cup lid 18 is placed on the container cup 8 through the electric telescopic rod 4 to protect the sample in the container cup 8. When the filter plate 21 needs to be replaced, the filter plate 21 can be lifted from the protrusion 23 to separate the filter plate 21 from the limiting post 24. Then, the new filter plate 21 can be installed on the protrusion 23.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
