Description

Technical Field

[0001] This utility model relates to the field of sewage sampling technology, and in particular to a rural sewage sample collection device. Background Technology

[0002] The water environment refers to the totality of various natural and related social factors surrounding human spaces and water bodies that can directly or indirectly affect human life and development, and their normal functions. In the detection and management of rural water environments, it is necessary to regularly sample and study water quality.

[0003] A sampling device for rural sewage treatment testing, disclosed in the prior art (CN219434429U), includes an extension tube. Connecting plates are fixed on both sides of the bottom of the extension tube, and a sampling tube is fixed between the connecting plates. A piston is installed inside the sampling tube, and a movable rod is fixed to the top of the piston. A handle is fixed to the top of the movable rod, which passes through the top of the sampling tube. By pulling a rope, the rope can drive the handle, movable rod, and piston to move upward, so that sewage enters the interior of the sampling tube through the hollow filter ball and the thin tube.

[0004] This design allows for sampling from deep within wastewater, and the four extension tubes are threaded together, enabling the sampling device to be adjusted in length to facilitate sampling at different depths. Furthermore, the four extension tubes can be disassembled and placed side-by-side, reducing the overall length of the sampling device and making it easier to carry. However, after each intake of wastewater, the device must be removed and the wastewater discharged into a storage container. When simultaneous sampling from various depths is required, multiple insertions and removals of the device are necessary, which is not convenient or efficient. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the need for multiple insertions and removals of the device when sampling sewage at various depths simultaneously, which is inconvenient and slow. Therefore, this invention proposes a rural sewage sampling device.

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

[0007] Design a rural sewage water sample collection device, including a sampling tube and a piston slidably installed in the sampling tube. A one-way suction component is installed at the inlet of the lower end of the sampling tube to prevent sewage from flowing out of the inlet. A one-way discharge component is provided on the top of the piston to guide sewage from below the piston to above the piston.

[0008] The top of the sampling tube is equipped with an output component for introducing wastewater into a container;

[0009] A spring is inserted inside the sampling tube, which is clamped between the piston and the inner wall of the sampling tube, and the spring is used to press down the piston;

[0010] A pull rope is fixed to the top of the piston, and an extension component is provided on the outer wall of the pull rope.

[0011] Furthermore, the one-way inhalation assembly includes a fixed base fixed to the inner wall of the lower end of the sampling tube and short shafts fixed to both sides of the fixed base. A collar is sleeved on one end of the pair of short shafts away from each other, and a cover plate located above the lower end inlet of the sampling tube is fixedly connected to the outer wall of the collar. A sealing gasket is adhered to the lower end face of the cover plate. A torsion spring is sleeved on the outer wall of the short shaft, and a collar and a fixed base are fixedly connected to both ends of the torsion spring, respectively.

[0012] Furthermore, the one-way discharge assembly includes a mounting base fixed to the top of the piston and a drain hole opened on the top of the piston. Short shafts are fixed on both sides of the mounting base, and a rotating ring and a second torsion spring are sleeved on the outer wall of the short shafts. The two ends of the second torsion spring are respectively fixedly connected to the rotating ring and the mounting base, and a sealing plate located above the drain hole is fixedly connected to the outer wall of the mounting base. A sealing gasket is adhered to the lower end face of the sealing plate.

[0013] Furthermore, the output component includes a drain outlet integrally formed on the top of the sampling tube, and a drain hose is fixedly connected to the upper end of the drain outlet for connecting a container.

[0014] Furthermore, the extension assembly includes an installation tube and several extension tubes sequentially sleeved on the pull rope from bottom to top, with the bottom of the installation tube penetrating and fixedly connected to the sampling tube, the lower end of the extension tube being fixedly provided with a sleeve, the upper ends of both the extension tube and the installation tube being inserted into the sleeve located above them, and the lower end of the extension tube being fixedly provided with a magnetic ring.

[0015] Furthermore, a hollow filter ball is fixedly connected to the water inlet at the lower end of the sampling tube.

[0016] The rural sewage sampling device proposed in this utility model has the following advantages: by pulling, releasing, and pulling the rope again, the piston can be raised, lowered, and raised again, so that sewage can be sequentially sucked into the space below the piston in the sampling tube, pressed into the space above the piston in the sampling tube, and then injected into the container through the output component to complete the sampling at one position. After removing the container, releasing the rope, installing a new container, and moving the sampling tube to different positions and depths, the above steps can be repeated, so that sewage can be continuously sampled at different positions and depths without removing the sampling tube, making it more convenient to use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4 As an embodiment of this utility model, a rural sewage water sample collection device is disclosed, including a sampling tube 1 and a piston 2 slidably installed in the sampling tube 1. The device is characterized in that: a one-way suction component 3 is installed at the inlet of the lower end of the sampling tube 1 to prevent sewage from flowing out of the inlet, and a one-way discharge component 4 is provided on the top of the piston 2 to guide sewage from below the piston 2 to above the piston 2.

[0024] The top of the sampling tube 1 is provided with an output component 5 for introducing sewage into a container;

[0025] A spring 6 is inserted inside the sampling tube 1, which is clamped between the piston 2 and the inner wall of the sampling tube 1, and the spring 6 is used to press down the piston 2;

[0026] The piston 2 is fixedly provided with a pull rope 7 at its top, and an extension component 8 is provided on the outer wall of the pull rope 7. A pull ring is fixedly provided at the upper end of the pull rope 7.

[0027] First, a long rod is formed by extending component 8 so that sampling tube 1 can be inserted into different positions and depths of sewage;

[0028] Pulling the pull rope 7 with the pull ring causes the piston 2 to rise, simultaneously closing the one-way discharge component 4 and opening the one-way suction component 3 to draw sewage into the space below the piston 2 inside the sampling tube 1 through the inlet of the sampling tube 1. Releasing the pull rope 7 causes the piston 2 to move down under the elastic force of the spring 6, opening the one-way discharge component 4 and closing the one-way suction component 3, squeezing the sewage below the piston 2 into the space above the piston 2. Pulling the pull rope 7 again closes the one-way discharge component 4 and opens the one-way suction component 3, causing the piston 2 to rise and squeezing the sewage into the drain outlet 51 and injecting it into the container through the output component 5, thus completing the sampling at one location.

[0029] In detail, the one-way suction assembly 3 includes a fixed seat 31 fixed on the inner wall of the lower end of the sampling tube 1 and short shafts 32 fixed on both sides of the fixed seat 31. A collar 33 is sleeved on one end of the pair of short shafts 32 away from each other, and a cover plate 34 located above the lower end inlet of the sampling tube 1 is fixedly connected to the outer wall of the collar 33. A sealing gasket 35 is adhered to the lower end face of the cover plate 34. A torsion spring 36 is sleeved on the outer wall of the short shaft 32, and the collar 33 and the fixed seat 31 are fixedly connected to both ends of the torsion spring 36 respectively. When the piston 2 is stationary, the collar 33 presses the cover plate 34 against the inner wall of the lower end of the sampling tube 1 under the action of the torsion spring 36.

[0030] When piston 2 rises, a negative pressure is generated below piston 2, which adsorbs and fixes the sealing plate 45 and sealing gasket 25 to the upper end of piston 2 and seals the drain hole 42. At the same time, sewage is sucked in through the hollow filter ball 9. The sucked sewage pushes open the cover plate 34 and enters the space below piston 2 in the sampling tube 1.

[0031] Specifically, the one-way discharge assembly 4 includes a mounting base 41 fixed to the top of the piston 2 and a drain hole 42 opened on the top of the piston 2. Short shafts are fixed on both sides of the mounting base 41, and a rotating ring 43 and a second torsion spring 44 are sleeved on the outer wall of the short shafts. The two ends of the second torsion spring 44 are fixedly connected to the rotating ring 43 and the mounting base 41, respectively. A sealing plate 45 located above the drain hole 42 is fixedly connected to the outer wall of the mounting base 41. A sealing gasket is adhered to the lower end face of the sealing plate 45. When the piston 2 is stationary, the rotating ring 43 presses the sealing plate 45 against the top of the piston 2 under the action of the second torsion spring 44.

[0032] The piston 2 moves down and generates positive pressure below it, pressing the cover plate 34 and the sealing gasket onto the inlet of the sampling tube 1 to seal the inlet of the sampling tube 1. At the same time, the piston 2 squeezes out the sewage, causing it to push open the sealing plate 45 and the sealing gasket and enter the space above the piston 2 inside the sampling tube 1.

[0033] Furthermore, the output component 5 includes a drain outlet 51 integrally formed on the top of the sampling tube 1, and a drain hose 52 is fixedly connected to the upper end of the drain outlet 51. The drain hose 52 is used to connect to the container.

[0034] It should be noted that the extension assembly 8 includes an installation tube 81 and several extension tubes 82 that are sequentially sleeved on the pull rope 7 from bottom to top. The bottom of the installation tube 81 passes through and is fixedly connected to the sampling tube 1. The lower end of the extension tube 82 is fixedly provided with a sleeve 83. The upper ends of the extension tube 82 and the installation tube 81 are both inserted into the sleeve 83 located above them. The lower end of the extension tube 82 is fixedly provided with a magnetic ring 84.

[0035] The sleeve 83 allows several extension tubes 82 and installation tubes 81 to be spliced ​​into a single long rod, and the extension tubes 82 and installation tubes 81 are magnetically fixed by the magnetic ring 84, thereby preventing them from detaching from the sleeve 83 under the action of gravity.

[0036] In some embodiments, a hollow filter ball 9 is fixedly connected to the water inlet at the lower end of the sampling tube 1, and the impurities in the sewage are filtered by the hollow filter ball 9.

[0037] Working method: Before use, straighten the pull ring so that the extension tube 82 and the mounting tube 81 are aligned with the sleeve 83 above them respectively, and insert them into the sliding sleeve 83 under the action of gravity, so that the magnetic ring 84 magnetically attracts the extension tube 82 and the mounting tube 81, thereby assembling several extension tubes 82 and mounting tubes 81 into a whole long rod.

[0038] Holding the uppermost extension tube 82 and the pull rope 7, the sampling tube 1 is submerged in rural sewage, and the hollow filter ball 9 at its lower end is moved to different positions and depths, thereby sampling sewage at different depths and positions;

[0039] Pulling the rope 7 causes the piston 2 to rise, creating negative pressure below the piston 2. This causes the sealing plate 45 and the sealing gasket to be attached to the upper end of the piston 2 and the drain hole 42 to be sealed. At the same time, the sewage is drawn in through the hollow filter ball 9. The drawn-in sewage pushes open the cover plate 34 and enters the space below the piston 2 in the sampling tube 1.

[0040] Releasing the pull rope 7 causes the piston 2 to move downward under the elastic force of the spring 6, squeezing the sewage in the sampling tube 1 and generating positive pressure to press the cover plate 34 and sealing gasket 35 onto the inlet of the sampling tube 1, sealing the inlet of the sampling tube 1. At the same time, the piston 2 squeezes out the sewage, causing it to push open the sealing plate 45 and sealing gasket and enter the space above the piston 2 inside the sampling tube 1.

[0041] Pull the rope 7 again to drive the piston 2 to rise, sucking the sewage into the space below the piston 2 in the sampling tube 1 through the hollow filter ball 9. At the same time, the sewage in the space above the piston 2 in the sampling tube 1 is squeezed into the drain outlet 51 and enters the container through the drain hose 52, completing the sampling at one location.

[0042] Remove the container and loosen the pull rope 7. Move the sampling tube 1 to different depths and positions, and repeat the above three steps to sample the sewage at different positions and depths.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
