Description

Technical Field

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

[0002] Water quality testing is an essential part of the water treatment process, affecting all aspects of human life and industrial production. Water quality testing allows us to understand the condition of the water, providing a basis for subsequent water treatment. The main components of water quality testing include pH testing, total solids testing, turbidity testing, and dissolved oxygen testing. Water quality testing typically involves the use of appropriate sampling or extraction devices. After sampling or extraction, the water sample is sent to a laboratory for testing. With the continuous development of technology, various types of water quality testing and extraction devices have emerged on the market.

[0003] In the prior art, a water quality testing and extraction device with publication number CN115753216A includes a conveying component, an extraction component, and a collection component. When extracting water samples, a telescopic rod is extended to a suitable length, and the telescopic sleeve is sent to a suitable position through the telescopic rod. Then, the winding rod is rotated to release the winding rope. The release of the winding rope causes the bottom end of the telescopic rod to move down, which drives the outer cylinder and the collection component to move down to a certain position in the water. However, the following problems still exist.

[0004] Most of the water samples obtained are retained in the sampling tube, and the water samples often contain a large number of impurity particles, which affects the water quality testing results. At the same time, the sampling tube height of the extraction devices on the market is fixed and difficult to change, making it difficult to meet the requirements of water sample extraction under different conditions.

[0005] Therefore, this application provides a water quality testing and extraction device to meet the requirements. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a water quality testing and extraction device that can solve the technical problems of existing technologies, such as water samples containing a large number of impurity particles affecting the water quality testing effect, and the fixed height of the sampling cylinder of the extraction device making it difficult to meet the requirements of water sample extraction under different conditions.

[0007] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a water quality testing and extraction device, comprising: an H-shaped support, a supporting component horizontally positioned on the H-shaped support; and a sampling mechanism mounted on the supporting component for extracting water samples. The sampling mechanism consists of a cylinder and a sampling cylinder with an open bottom. A filter cage is installed at the bottom of the sampling cylinder. A push-pull column extends vertically from the inner cavity of the sampling cylinder, and a rubber stopper is movably installed inside the sampling cylinder. The rubber stopper is movably and tightly fitted against the inner cavity of the sampling cylinder and is fixedly connected to the bottom end of the push-pull column. The top end of the push-pull column extends above the sampling cylinder and is fixedly connected to the piston rod at the bottom end of the cylinder. A liquid outlet hole is provided on one side of the sampling cylinder, and a conduit is fitted at the liquid outlet hole.

[0008] A container for receiving water samples discharged through a conduit;

[0009] The H-shaped bracket has an adjustment mechanism installed in the middle of its frame for adjusting the height of the support component and the sampling mechanism. The adjustment mechanism consists of a screw that passes vertically through the bottom of the support component and a pressure block located on the support component and screwed to the outer surface of the screw.

[0010] Preferably, the cavity of the liquid outlet hole is connected to the inner cavity of the sampling cylinder. The liquid outlet hole is installed in the upper part of the cylinder body of the sampling cylinder. The bottom surface of the cavity of the liquid outlet hole is a downward inclined surface with an inclination of 10-75 degrees.

[0011] Preferably, the H-shaped bracket consists of a first upright plate, a second upright plate, and a horizontal plate connecting the first upright plate and the second upright plate. The bottom of the H-shaped bracket is provided with a support base, on which a container is placed. The bottom of the support base is equipped with casters.

[0012] Preferably, the support component includes a support plate and a fixing frame, the fixing frame being located on the support plate and used to support the cylinder, and the top right side of the support plate having an installation hole for installing the sampling cylinder.

[0015] Preferably, the pressing block has a ring-shaped top view and a holding post is installed on the outer side wall of the pressing block. When the pressing block rotates clockwise, a downward spiral thrust is generated on the screw to push down and drive the support component to move down, thereby changing the working height of the support component and the sampling mechanism.

[0016] Compared with known public technologies, the technical solution provided by this utility model has the following beneficial effects:

[0017] 1. This utility model utilizes the gravity slope formed by the bottom surface of the liquid outlet cavity to accelerate the extraction speed of water samples from the sampling tube, allowing the extracted water samples to be extracted smoothly and quickly. With the aid of a conduit, the water samples can be successfully extracted and collected in the container. Simultaneously, with the assistance of an adjustment mechanism, the clockwise rotation of the pressure block generates a downward spiral thrust on the screw, driving the support component downwards. This allows for convenient adjustment of the sampling mechanism's operating height to adapt to different water sample extraction conditions, facilitating the widespread use of water quality testing extraction devices. It solves the technical problems of existing technologies where water samples contain a large number of impurities affecting water quality testing results, and the fixed operating height of the sampling tube makes it difficult to meet the needs of water sample extraction under different conditions.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] The aforementioned water quality testing and extraction device includes an H-shaped support, a support component horizontally placed on the H-shaped support, a sampling mechanism mounted on the support component for extracting water samples, and a container for holding the water samples. In this embodiment, the sampling mechanism consists of a cylinder 14 and a sampling cylinder 9 with an open bottom. A filter cage 12 is installed at the bottom of the sampling cylinder 9. The filter cage 12 allows for pre-filtration of the water sample during extraction, facilitating water sample extraction and water quality testing. A push-pull column 10 extends vertically from the inner cavity of the sampling cylinder 9, and a rubber stopper 11 is movably installed inside the sampling cylinder 9. The rubber stopper 11 is attached to the inner cavity of the sampling cylinder 9 and is fixedly connected to the bottom end of the push-pull column 10. The top end of the push-pull column 10 extends above the sampling cylinder 9 and is fixedly connected to the piston rod at the bottom end of the cylinder 14. A liquid outlet hole 15 is provided on one side of the sampling cylinder 9, and a conduit 16 is sleeved at the liquid outlet hole 15. A container is used to collect the water sample discharged by the conduit 16. The container is, but is not limited to, a container trough 8. A scale is provided on the cavity of the container 8 so as to visually obtain the liquid volume in the container. The structure and principle of the cylinder 14 and the spring 601 are well known technologies in the market, so they will not be described in detail here.

[0029] Furthermore, an adjustment mechanism for adjusting the height of the support component and sampling mechanism is installed in the middle of the H-type support frame. The adjustment mechanism consists of a screw 6 that passes vertically through the bottom end of the support component and a pressure block 7 located on the support component and screwed to the outer surface of the screw 6. The pressure block 7 has a ring-shaped structure when viewed from above. A holding post is installed on the outer wall of the pressure block 7. When the pressure block 7 rotates clockwise, it generates a downward spiral thrust on the screw 6, which pushes down and drives the support component to move down to change the height of the support component and sampling mechanism.

[0030] Furthermore, the cavity of the liquid outlet hole 15 is connected to the inner cavity of the sampling cylinder 9. The liquid outlet hole 15 is installed in the upper part of the cylinder of the sampling cylinder 9. The bottom surface of the cavity of the liquid outlet hole 15 is a downward inclined surface with an inclination of 10-75 degrees. The inclined surface allows the water sample extracted in the sampling cylinder 9 to be smoothly and quickly exported. Under the action of the guide tube 16, the water sample is successfully exported and collected on the holding tank 8. The guide tube 16 is made of, but is not limited to, a flexible plastic tube. The inclination of the bottom surface of the cavity of the liquid outlet hole 15 is preferably 30 degrees, 45 degrees or 60 degrees, so as to form a gravity slope on the bottom surface of the cavity of the liquid outlet hole 15, which accelerates the export speed of the water sample in the sampling cylinder 9.

[0031] Furthermore, the aforementioned H-shaped support consists of a first upright plate 2, a second upright plate 4, and a horizontal plate 3 connecting the first upright plate 2 and the second upright plate 4. The bottom of the H-shaped support is provided with a support base 1, on which a container is placed. Casters are installed at the bottom of the support base 1. The cooperation between the support base 1 and the casters facilitates the movement and use of the water quality testing and extraction device. The bottom end of the screw 6 is fixed to the support base 1, and the outer surface of the screw 6 is located on the horizontal plate 3. A spring 601 is fitted between the support component and the support component; wherein, the support component includes a support plate 5 and a fixing frame 13, the fixing frame 13 is located on the support plate 5 and is used to support the cylinder 14, and the top right side of the support plate 5 has an installation hole 504 for installing the sampling cylinder 9; the length of the support plate 5 exceeds the lateral length of the H-shaped bracket, and the top of the support plate 5 has a screw hole 501 and two sets of through holes, the two sets of through holes being the first through hole 502 and the second through hole 503.

[0032] Furthermore, the first upright plate 2 passes vertically through the first through hole 502, and the second upright plate 4 passes vertically through the second through hole 503. The rod of the screw 6 extends spirally into the screw hole 501, and the bottom end of the rod of the screw 6 passes through the horizontal plate 3 and is fixed on the support base 1. When the pressure block 7 is rotated clockwise, it can move spirally downward along the outer surface of the screw 6, thereby moving the support plate 5 smoothly downward, thus changing the working height of the sampling cylinder 9. At this time, the spring 601 will generate elastic deformation when it is pressed down, reducing the shaking and wear caused by the downward movement of the support plate 5. When the pressure plate 7 is rotated counterclockwise, it causes the pressure block 7 to move spirally upward along the outer surface of the screw 6, thereby causing the spring 601 to generate elastic deformation and push upward, and the support plate 5 moves upward smoothly and quickly, changing the working height of the sampling cylinder 9.

[0033] The complete working principle and steps of the above embodiments are as follows:

[0034] In this utility model, the water quality testing and extraction device allows for pre-adjustment of the sampling cylinder 9's height and position according to usage needs. The filter cage 12 at the bottom of the sampling cylinder 9 is then inserted into the water sampling position. The cylinder 14 is then activated, causing the push-pull column 10 to pull the rubber stopper 11 upwards, generating an upward suction force within the sampling cylinder 9. This draws the water from the filter cage 12 into the sampling cylinder 9. Once the water reaches the liquid outlet 15, the cylinder 14 stops, and the water in the sampling cylinder 9 is discharged through the liquid outlet. The sample enters the holding tank 8 through the hole 15 and the conduit 16. After the water sample in the sampling tube 9 is completely extracted, the cylinder 14 is restarted to drive the push-pull column 10 and the rubber stopper 11 to move down and expel the air in the sampling tube 9. Then, it moves up again, at which point the rubber stopper 11 moves up and generates suction in the sampling tube 9, drawing the water sample into the sampling tube 9. The water sample moves to the liquid outlet hole 15 and is then guided into the holding tank 8 by the conduit 16. The amount of water sample extracted can be visually obtained through the scale on the holding tank 8, thus completing the water sample extraction work.

[0035] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
