Sampling devices are needed in the process of water environment sampling.

[0003] However, existing water sampling devices are not convenient for sampling water bodies at a distance, have a limited range of applications, and cannot fix the inlet pipe at a fixed position on the surface water, making sampling inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a surface water sampling device that solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a surface water sampling device, comprising a peristaltic pump; multiple sections of an electric telescopic rod are horizontally fixedly mounted on the peristaltic pump via a bracket; a polyethylene tube is mounted on the multiple sections of the electric telescopic rod via several large-eye guide rings; a sample collection bottle is placed on one side of the peristaltic pump; one end of the polyethylene tube passes through the peristaltic pump and is connected to the sample collection bottle; an anti-floating sinker is fixedly connected to the other end of the polyethylene tube; a float is connected to the anti-floating sinker via a connecting rope; and the anti-floating sinker is connected to the telescopic end of the multiple sections of the electric telescopic rod via a hanging rope.

[0006] The multi-section electric telescopic rod includes a reducer, a main carbon tube, and auxiliary carbon tubes. The reducer is fixedly installed on a bracket, the main carbon tube is fixedly installed at one end of the reducer, and several auxiliary carbon tubes are slidably connected to each other. One of the auxiliary carbon tubes is slidably installed inside the main carbon tube. The multi-section electric telescopic rod is equipped with a drive assembly that drives several auxiliary carbon tubes to extend and retract.

[0007] Preferably, the drive assembly includes a drive gear and a driven gear, the drive gear and the driven gear meshing with each other, the drive gear being fixedly mounted on the drive end of the reducer, and a spool being fixedly mounted on both the drive gear and the driven gear.

A pair of first bearing pulleys and a pair of second bearing pulleys are rotatably installed at both ends of several secondary carbon tubes. The pair of first bearing pulleys and the pair of second bearing pulleys are connected by multiple strands of stainless steel wire.

[0009] Preferably, a tripod is provided below the multi-section electric telescopic rod.

[0010] Beneficial effects

[0011] This invention provides a surface water sampling device, which has the following beneficial effects:

[0012] 1. Equipped with a peristaltic pump, the device allows water from the river surface to be piped into a sample collection bottle via a polyethylene tube. The sample collection bottle is used to collect samples. An anti-floating head allows the end of the polyethylene tube to be submerged below the river surface for easy water collection. The depth of the anti-floating head can be adjusted using a float and a rope. The device also features a multi-section electric telescopic rod, which, when activated, extends and retracts, thereby moving the polyethylene tube and the anti-floating head. This allows for sampling of river surface water at different distances, expanding the device's applicability.

[0013] 2. The multi-section electric telescopic rod can be extended and retracted by installing a drive component. It is equipped with a main carbon tube and a secondary carbon tube, and the secondary carbon tubes are slidably connected. Therefore, the secondary carbon tube with the largest diameter can extend and retract with the main carbon tube and with each other, thus enabling multi-section extension and retraction.

[0014] 3. The device is equipped with a drive gear. Rotation of the reducer drive end drives the drive gear, which in turn meshes with the driven gear, causing the driven gear to rotate. During this rotation, multiple strands of stainless steel wire can be wound and unwound between two reels. The transmission of these multiple strands drives a pair of first-bearing pulleys and a second-bearing pulley. The multiple strands of stainless steel wire, through fixed point one, can pull the secondary carbon tube, enabling its extension and retraction. One end of the secondary carbon tube is fixedly connected to one end of the main carbon tube. When the secondary carbon tube moves, it moves the pair of first-bearing pulleys and the second-bearing pulley. At this time, fixed point two remains stationary, while fixed point three moves under the pull of the multiple strands of stainless steel wire, thus moving the next section of the secondary carbon tube. This process continues in this manner, allowing multiple sections of the secondary carbon tube to move, easily achieving the extension and retraction of multiple sections of the carbon tube.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Wherein, directional terms such as "upper" and "lower" mentioned herein are used in conjunction with... Figure 1 The orientation is used as a reference.

[0019] Please see Figure 1-2 This utility model provides a technical solution: a surface water sampling device, including a peristaltic pump 1; a multi-section electric telescopic rod 2 is horizontally fixedly installed on the peristaltic pump 1 by a bracket, and a polyethylene tube 5 is installed on the multi-section electric telescopic rod 2 by a number of large-eye guide rings 4. A sample collection bottle 6 is placed on one side of the peristaltic pump 1, one end of the polyethylene tube 5 passes through the peristaltic pump 1 and is connected to the sample collection bottle 6, and the other end of the polyethylene tube 5 is fixedly connected to an anti-floating sinker 7. A float 3 is connected to the anti-floating sinker 7 by a connecting rope, and the anti-floating sinker 7 is connected to the telescopic end of the multi-section electric telescopic rod 2 by a hanging rope 9.

[0020] By installing a peristaltic pump 1 and starting it, water from the river surface can be introduced into a sample collection bottle 6 through a polyethylene pipe 5. The sample collection bottle 6 can be used to collect samples. By installing an anti-floating sinker 7, the end of the polyethylene pipe 5 can be inserted below the river surface for easy water collection. By installing a multi-section electric telescopic rod 2 and starting it, the anti-floating sinker 7 can be moved, thus enabling sampling of river surface water at different distances and expanding the applicability of the device. The depth of the anti-floating sinker 7 can be adjusted by using a float 3 and a hanging rope 9.

[0021] Furthermore, the multi-section electric telescopic rod 2 includes a reducer 21, a main carbon tube 26, and auxiliary carbon tubes 27. The reducer 21 is fixedly installed on the bracket, and the main carbon tube 26 is fixedly installed at one end of the reducer 21. Several auxiliary carbon tubes 27 are slidably connected to each other, with one auxiliary carbon tube 27 slidably installed inside the main carbon tube 26. The multi-section electric telescopic rod 2 is equipped with a drive assembly that drives the extension and retraction of several auxiliary carbon tubes 27. The reducer 21 drives the drive assembly to work, and the drive assembly drives the extension and retraction of the multi-section electric telescopic rod 2. Since the main carbon tube 26 and auxiliary carbon tubes 27 are installed and the auxiliary carbon tubes 27 are slidably connected to each other, the auxiliary carbon tube 27 with the largest diameter can extend and retract with the main carbon tube 26, as well as with the auxiliary carbon tubes 27 themselves, thus enabling multi-section extension and retraction.

[0022] Furthermore, the drive assembly includes a drive gear 22 and a driven gear 23, which mesh with each other. The drive gear 22 is fixedly mounted on the drive end of the reducer 21. Both the drive gear 22 and the driven gear 23 are fixedly mounted with spools 28. A pair of first bearing pulleys 24 are rotatably mounted on one end of the main carbon tube 26 near the reducer 21, and a second bearing pulley 29 is rotatably mounted on the other end of the main carbon tube 26. Multiple strands of stainless steel wire 25 are wound around one spool 28, and the other end of the multiple strands of stainless steel wire 25 passes through the first bearing pulley 24 and the second bearing pulley 29. The bearing pulley 29 is fixedly connected to another reel 28; a multi-strand stainless steel wire 25 near one of the second bearing pulleys 29 is fixedly connected to the end of the auxiliary carbon tube 27 as a fixed point one. Several auxiliary carbon tubes 27 have a pair of first bearing pulleys 24 and a pair of second bearing pulleys 29 rotatably mounted at both ends. The pair of first bearing pulleys 24 and the pair of second bearing pulleys 29 are connected by a multi-strand stainless steel wire 25. The multi-strand stainless steel wire 25 at one end of the auxiliary carbon tube 27 adjacent to the main carbon tube 26 is fixedly connected to one end of the main carbon tube 26 as a fixed point two. The multi-strand stainless steel wire 25 at the other end of the 27 is fixedly connected to the end of the adjacent next carbon tube 27 as fixing point three. The multi-strand stainless steel wire 25 at the pair of first bearing pulleys 24 inside the next carbon tube 27 is fixedly connected to the end of the carbon tube 27 as fixing point four. Several carbon tubes 27 are connected in this manner. By installing a drive gear 22, the rotation of the drive end of the reducer 21 can drive the drive gear 22 to rotate. By meshing the drive gear 22 with the driven gear 23, the driven gear 23 can be driven to rotate. During the rotation of the drive gear 22 and the driven gear 23... In this device, multiple strands of stainless steel wire 25 can be wound and unwound between two reels 28. During the transmission of the multiple strands of stainless steel wire 25, a pair of first bearing pulleys 24 and a second bearing pulley 29 can be rotated. The multiple strands of stainless steel wire 25 can pull the auxiliary carbon tube 27 to move through fixed point one, thus completing the extension and retraction of the auxiliary carbon tube 27. The multiple strands of stainless steel wire 25 at one end of the auxiliary carbon tube 27 are fixedly connected to one end of the main carbon tube 26. When the auxiliary carbon tube 27 moves, it drives the pair of first bearing pulleys 24 and a second bearing pulley 29 to move. At this time, fixed point two remains stationary, while steel wire fixed point three moves under the pull of the multiple strands of stainless steel wire 25, thereby driving the next auxiliary carbon tube 27 to move. In this way, multiple auxiliary carbon tubes 27 can be moved, thus easily realizing the extension and retraction of multiple carbon tubes.

[0023] Furthermore, a tripod 8 is installed below the multi-section electric telescopic pole 2, which can support the multi-section electric telescopic pole 2.

[0024] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0025] The working principle and usage process of this utility model are as follows: During use, the peristaltic pump 1 is placed on the ground. According to sampling requirements, the reducer 21 is started, driving the drive gear 22 to rotate. The drive gear 22 meshes with the driven gear 23, causing the driven gear 23 to rotate, which in turn drives the two reels 28 to rotate. During the transmission of the multi-strand stainless steel wire 25, a pair of first bearing pulleys 24 and a second bearing pulley 29 rotate. The multi-strand stainless steel wire 25, through a fixed point one, can pull the auxiliary carbon tube 27 to move, completing the extension and retraction of the auxiliary carbon tube 27 adjacent to the main carbon tube 26. When the auxiliary carbon tube 27 moves, it drives the pair of first bearing pulleys 24 and the second bearing pulley 29 to move. At this time, the fixed point two remains stationary. The steel wire fixing point 3 moves under the pull of multiple stainless steel wires 25, which can drive the next carbon tube 27 to move. In this way, multiple sections of carbon tube 27 can be moved, so the extension and retraction of multiple sections of carbon tube can be easily realized until the anti-floating sinker 7 is located at the sampling point. Then, the peristaltic pump 1 is started to pump the river surface water at the sampling point into the polyethylene tube 5 and then into the sample collection bottle 6 for collection.
