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 monitoring refers to the process of regularly testing and evaluating the physical, chemical and biological properties of water. It is an important means to protect water resources, safeguard human health and maintain sustainable environmental development. Water is one of the most precious resources on earth. Protecting water resources is essential to maintaining ecological balance and sustainable human development. By monitoring various indicators in water bodies, we can understand the water quality in a timely manner and take appropriate measures to manage and protect it; by monitoring the content of harmful substances in water, such as heavy metal pollution, pesticide residues, etc., we can promptly discover water pollution problems and take appropriate management measures.

[0003] The prior art, for example, a patent with a publication number of "CN 209820863 U" discloses a water quality sampling device for environmental testing, which achieves a good sampling effect through the cooperation of a bottom plate, a moving wheel, a support column, an electric push rod, a fixed seat, a lifting groove, a first rolling bearing, a threaded rod, a first transmission wheel, a first forward and reverse motor, a first forward and reverse shaft, a second transmission wheel, a belt, a threaded plate, a sleeve, a sampling bottle, a sampling port, a discharge port, a sliding rod, a sealing plate, a reset spring, a fixing ring, a second rolling bearing, a supporting rotating shaft, a reel, a second forward and reverse motor, a second forward and reverse shaft, a driving bevel gear, a driven bevel gear, a nylon rope and a pulley, and can accurately sample water quality at different depths; for another example, a patent with a publication number of "CN 217006479 U" discloses a stratified water quality sampler for environmental testing, which uses a mobile floating box to float on the water surface, and controls the communication between multiple water inlet holes and multiple corresponding water storage chambers by controlling the position between the sleeve and the water storage pipe, so as to simultaneously take water samples from different water layers. Both of the above patents have achieved the effect of being able to sample water quality at different depths, but the first patent can only be operated by staff at the waterside or on the boat for layered sampling. The length of the water storage pipe and casing used in the second patent is fixed, and the water storage pipe and casing will be frequently replaced in the face of sampling requirements at different depths. In the process of water quality sampling, it is necessary to sample water quality in different places and at different depths to determine the water quality of the entire area. In the past, staff rowed boats to different locations for sampling. However, this sampling method is time-consuming and labor-intensive. Due to the buoyancy of the hull, the actual depth of the detection equipment placed on the hull will change greatly during the fixed-point depth sampling process. Utility Model Content

[0004] The utility model aims to provide a water quality detection sampling device to solve the problems of inaccurate sampling depth and time-consuming and labor-intensive sampling when stratified sampling of water quality in a region.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a water quality detection sampling device, comprising a box, a collection component and a storage component, the collection component comprising a telescopic rod, a lifting block and a collector, any vertical side wall of the box is provided with a movable door, the movable door is connected with a traction rope, a latex pad is provided on one side of the bottom of the box, a cross opening is provided in the middle of the latex pad, the outermost side of the telescopic rod is connected to the top of the box, the telescopic rod passes downward through the latex pad and is located underwater, the lifting block is connected to the innermost end of the telescopic rod, the collector is connected to the bottom of the lifting block, the bottom of the collector is connected with a pipette, a water absorption component for absorbing water is provided in the collector, the storage component for storing sampled water is connected in the box, a controller is provided at the outer top of the box, the controller is electrically connected to the telescopic rod, the water absorption component and the storage component.

[0006] The working principle of the utility model is as follows: when water quality sampling is required, different sampling depths and sampling intervals are set on the controller. At this time, the sampling device is placed on the water surface, one end of the traction rope is fixed on the shore, and the sampling device moves on the water surface. When the sampling time is reached, the telescopic rod is extended downward through the latex pad to reach underwater, and the water absorption component starts to operate to absorb water into the collector. After the collection is completed, the telescopic rod retracts, and when it returns to the initial state, the storage component operates and moves to the bottom of the collector. At this time, the water absorption component is operated in reverse, and the collected water enters the storage component and is collected. The sampling device continues to move on the water surface, and when it moves to the next sampling time, the set depth is sampled. After all the sampling is completed, the traction rope is controlled to make the sampling device return to the shore, and the movable door of the box is opened to take out the water stored in the storage component.

[0007] The beneficial effects of the utility model are as follows: through the arrangement of the telescopic rod, the water absorption component and the storage component, the sampling device can automatically and continuously perform water quality sampling without human operation, and the sampling device can achieve water quality sampling at different locations with the same depth in the same area and water quality sampling at different depths in different locations by setting the sampling time and the sampling depth, thereby improving the diversity of water quality sampling, providing more data sources for water quality detection, and further reducing the error of the sampling depth.

[0008] Furthermore, the storage assembly includes a motor, a connection plate and a plurality of connection columns, the motor is connected to the outer top of the box, the output shaft of the motor passes through the box downward and is connected to the connection plate, a plurality of connection columns are arranged around the outer edge of the connection plate, the connection plate and the plurality of connection columns are located in the same horizontal plane, and a card slot is provided at one end of the connection column away from the connection plate, and a collection tank is connected in the card slot. When working, the telescopic rod is aligned with the gaps of the plurality of connection columns, and after the telescopic rod descends and the sampling is completed, it returns to the original position, the motor is started, and the output shaft drives the connection plate to rotate, so that the plurality of connection columns rotate. When the telescopic rod is aligned with the collection tank on one of the connection columns, the motor is stopped, and the telescopic rod is controlled to descend, and the pipette is aligned with the collection tank, and the water quality sample enters the collection tank and is collected.

[0009] Furthermore, a silicone plug is connected to the opening of the collection tank, and a cross opening is arranged at the center of the silicone plug.

[0011] Furthermore, the outer ring of the box is provided with a floating plate, and the sampling device can be stabilized on the water surface by the arrangement of the floating plate.

[0012] Furthermore, the box body is divided into two upper and lower cavities, the upper cavity is the first cavity, the lower cavity is the second cavity, the connection plate is located in the first cavity, the telescopic rod passes through the first cavity and the latex pad is located underwater, and openings are provided on both sides of the middle of the second cavity.
