Description

Technical Field

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

[0002] Water conservancy projects are a general term for various engineering constructions undertaken to control, utilize, and protect surface and underground water resources and the environment. Water conservancy projects are constructed to eliminate water hazards and develop and utilize water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, rafts, and fishways to achieve their objectives.

[0003] Water quality testing is a crucial part of water conservancy projects. Since water quality can vary at different depths, it's necessary to collect samples from various depths. Sampling usually requires personnel to directly take samples from the water source, but this is more complicated for shallow and deep water sources, potentially affecting the accuracy of the sampling. Utility Model Content

[0004] This utility model discloses a lifting sampling device for environmental water quality testing, which mainly solves the problem that most sampling personnel need to directly take sampling items to sample water sources.

[0005] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows:

[0006] This utility model provides a lifting sampling device for environmental water quality testing, including a working platform, a lifting mechanism on the working platform, a lifting rod, and a sampling mechanism at the bottom end of the lifting rod;

[0007] The sampling mechanism includes a sampling rod mounted on a lifting rod. The sampling rod has multiple spaced mounting brackets, each mounting bracket holding a sampling bottle. Each sampling bottle has a sealing cap, which is controlled to move up and down relative to the sampling bottle via a control component. A lifting plate is mounted on the sealing cap. A guide rod is positioned on the mounting bracket corresponding to the lifting plate, passing through the lifting plate. A limit ring is mounted at the end of the guide rod, and an elastic element is mounted on the guide rod. One end of the elastic element is supported on the limit ring, and the other end is supported on the lifting plate.

[0008] In one embodiment, the lifting mechanism further includes a housing, in which a rotating component is rotatably connected. The rotating component is threadedly connected to the lifting rod, and the rotating component is driven by a lifting motor. The lifting rod is provided with a concave rotation limiting groove, and the housing is provided with a rotation limiting rod, which is embedded in the rotation limiting groove.

[0009] In one embodiment, the rotating component is a turbine, and the output end of the lifting motor is provided with a worm gear, which meshes with the rotating component.

[0010] In one embodiment, the control element includes a control rope, one end of which passes sequentially through a lifting rod and a sampling rod, and the other end is wound around a winding rod. The winding rod is rotatably connected to a working platform and is driven by a control motor. The lifting plate is mounted on the control rope.

[0011] In one embodiment, the sampling rod has a control hole extending vertically through the control rope at the position corresponding to the control rope, allowing the control rope to pass through the control hole. The sampling rod has a movable hole communicating with the control hole at the position corresponding to the lifting plate, and one end of the lifting plate passes through the movable hole and is placed in the control hole.

[0012] In one embodiment, a protective sleeve is provided on the working platform corresponding to the position of the lifting rod, and the protective sleeve covers the lifting rod.

[0013] The advantages or beneficial effects of the above technical solution include at least the following: When water quality testing is required, the entire device can be installed on the support frame via a working platform. Then, the lifting rod of the lifting mechanism drives the sampling rod of the sampling mechanism to rise and fall until each sampling bottle reaches the detection depth in the water. The sealing cap can then be opened by the control component, allowing water at each depth to enter the corresponding sampling bottle. Afterward, the control component drives the lifting plate in the opposite direction, causing the sealing cap to descend along the guide rod and cover the sampling bottle. This completes the sampling of water sources at different depths. The lifting mechanism then raises the sampling mechanism above the water surface, allowing for subsequent testing of the water samples. This facilitates simultaneous sampling of water sources at different depths, avoids the need for manual sampling of water sources, and prevents water sources at different depths from affecting each other's test results.

[0032] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information.

[0033] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a lifting sampling device for environmental water quality testing, including a working platform 1, a lifting mechanism 2 on the working platform 1, the lifting mechanism 2 including a lifting rod 21, and a sampling mechanism 3 at the bottom end of the lifting rod 21.

[0034] The sampling mechanism 3 includes a sampling rod 31 mounted on a lifting rod 21. The sampling rod 31 is provided with multiple spaced mounting brackets 32. Each mounting bracket 32 ​​is provided with a sampling bottle 33. Each sampling bottle 33 is provided with a sealing cap 34. The sealing cap 34 is controlled to move up and down relative to the sampling bottle 33 by a control component 4. The sealing cap 34 is provided with a lifting plate 341. A guide rod 321 is provided on the mounting bracket 32 ​​at a position corresponding to the lifting plate 341. The guide rod 321 passes through the lifting plate 341. A limit ring 322 is installed at the end of the guide rod 321. An elastic element 35 is provided on the guide rod 321. One end of the elastic element 35 is supported on the limit ring 322, and the other end is supported on the lifting plate 341.

[0035] With the above structure, when water quality testing is required, the entire device can be installed on the support frame via the work platform 1. Then, the lifting rod 21 of the lifting mechanism 2 drives the sampling rod 31 of the sampling mechanism 3 to rise and fall until each sampling bottle 33 reaches the detection depth in the water. Then, the sealing cap 34 can be opened by the control component 4, allowing water at each depth to enter the corresponding sampling bottle 33. Afterward, the control component 4 drives in the reverse direction, and the elastic force of the elastic component 35 pushes the lifting plate 341, causing it to lower the sealing cap 34 along the guide rod 321 to cover the sampling bottle 33. This completes the sampling of water sources at different depths. Then, the lifting mechanism 2 raises the sampling mechanism 3 above the water surface, and the water samples can be tested subsequently. This facilitates simultaneous sampling of water sources at different depths, avoids manual sampling of water sources, and prevents water sources at different depths from affecting each other's test results.

[0036] In one embodiment, see Figure 1 and Figure 2The lifting mechanism 2 also includes a housing 22, in which a rotating component 23 is rotatably connected. The rotating component 23 is threadedly connected to the lifting rod 21, and is driven by a lifting motor 26. The lifting rod 21 has a recessed rotation-limiting groove 211, and the housing 22 has a rotation-limiting rod 25 embedded in the rotation-limiting groove 211. In practical applications, the rotation of the lifting rod 21 is limited by the cooperation of the rotation-limiting rod 25 and the rotation-limiting groove 211. Furthermore, through the threaded connection between the lifting rod 21 and the rotating component 23, the lifting rod 21 can be raised or lowered after the lifting motor 26 drives the rotating component 23 to rotate.

[0037] The rotating component 23 is a turbine, and the output end of the lifting motor 26 is equipped with a worm gear 24, which meshes with the rotating component 23. In practical applications, the turbine of the rotating component 23 and the worm gear 24 work together to transmit the power of the lifting motor 26 to the rotating component 23, enabling the rotating component 23 to rotate and thus control the lifting and lowering of the lifting rod 21.

[0038] In one embodiment, see Figure 1 , Figure 3 and Figure 4 The control component 4 includes a control rope 41. One end of the control rope 41 passes through the lifting rod 21 and the sampling rod 31 in sequence, and the other end is wound around a winding rod 42. The winding rod 42 is rotatably connected to the working platform 1 and is driven by a control motor 43. The lifting plate 341 is mounted on the control rope 41. In practical applications, through the cooperation of the control rope 41 with the winding rod 42 and the control motor 43, the control motor 43 drives the winding rod 42 to control the winding rod 42 to wind or release the control rope 41. This allows the control rope 41 to drive the lifting plate 341 to rise and fall, thereby controlling the opening or closing of the sealing cap 34 and the sampling bottle 33.

[0039] The sampling rod 31 has control holes 311 extending vertically through it, corresponding to the position of the control rope 41, allowing the control rope 41 to pass through the control holes 311. The sampling rod 31 has a movable hole 312 corresponding to the position of the lifting plate 341, communicating with the control holes 311. One end of the lifting plate 341 passes through the movable hole 312 and is placed within the control hole 311. In practical applications, the cooperation of the control holes 311 and the movable hole 312 facilitates the installation and connection of the control rope 41 and the lifting plate 341.

[0040] In one embodiment, see Figure 1 A protective sleeve 5 is provided on the work platform 1 corresponding to the position of the lifting rod 21, and the protective sleeve 5 covers the lifting rod 21. In actual use, the protective sleeve 5 can protect the part of the lifting rod 21 located above the work platform 1, and at the same time prevent the operator from touching it during the lifting process.

[0041] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] Those skilled in the art should understand that the above embodiments are merely for clearly illustrating the present invention and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications can be made based on the above-described invention, and these changes or modifications still fall within the scope of the present invention.
