Detailed Implementation

[0020] refer to Figures 1-4A water sampling device that is easy to install and maintain includes a supporting beam 1, a guide column 2, a sampling box 3, a lifting mechanism, and a pumping assembly for water sampling. The supporting beam 1 is fixed at the sampling point. For example, when used for water sampling from a water channel 21, one end of the supporting beam 1 is anchored to one side of the water channel 21. The upper end of the guide column 2 is fixedly connected to the supporting beam 1 (preferably welded), and the lower end of the guide column 2 is anchored to the bottom of the water channel 21. The sampling box 3 is slidably mounted on the guide column 2 and is driven to move up and down by the lifting mechanism. Specifically, two (or more) sliders are provided in the height direction of the sampling box 3. A slide rail 20 is installed on the guide column 2, and the sliders cooperate with the slide rail 20 to ensure that the sampling box 3 slides smoothly up and down along the guide column 2.

[0021] In addition to the above, the system also includes a maintenance ladder 7 and a maintenance platform 8. The maintenance platform 8 is fixed at the sampling point and connected to the guide column 2. Specifically, the maintenance platform 8 is connected to a tie rod 801, the other end of which is anchored to the wall of the water channel 21. The maintenance platform 8 is bolted to the guide column 2. One end of the maintenance ladder 7 is connected to the maintenance platform 8, and the other end extends to the bank of the sampling point. In practical applications, the maintenance ladder 7 is anchored to the wall of the water channel 21 at every other end. If the maintenance ladder 7 is short, it can be anchored to the wall of the water channel 21 only at both ends. Furthermore, a fence is installed around the maintenance platform 8 to ensure the safety of installation and maintenance personnel.

[0022] The pumping assembly includes a self-priming pump 6, a drain hose 9, and a water intake pipe 11. The self-priming pump 6 is located inside the sampling box 3. The self-priming pump 6 draws water through the water intake pipe 11 and sends the water into the water sample receiving device 10 through the drain hose 9. In practical applications, the water sample receiving device 10 can only temporarily store the obtained water sample, or it can have other functions, such as water sample packaging.

[0023] As an alternative, the lifting mechanism in this embodiment includes a rack 4, a gear (not shown), and a drive element 5. The drive element 5 is preferably a servo motor. The rack 4 is fixed to the guide column 2, and the gear meshes with the rack 4. The drive element 5 is fixed inside the sampling box 3 and drives the gear to rotate. When the gear rotates, it drives the sampling box 3 to move up and down as a whole. It is easy to understand that in other embodiments, the lifting mechanism can of course adopt other structures, such as a structure using a winch to lift the sampling box 3 via a rope, similar to the previous application.

[0024] Based on the above, the pumping assembly in this embodiment further includes a conduit 12 and a connecting hose 13. The conduit 12 is fixed to the bottom of the sampling box 3, the water intake pipe 11 passes through the conduit 12, and the connecting hose 13 connects the water intake pipe 11 and the self-priming pump 6. It is worth noting that, through the above arrangement, the lower end of the water intake pipe 11 can be kept away from the sampling box 3, thereby preventing the electrical components in the sampling box 3 from getting wet.

[0025] In this embodiment, a tube stabilizer 15 is provided in the middle of the tube 12. The tube stabilizer 15 is slidably connected to the guide column 2. Based on the slide rail 20 installed on the guide column 2, the tube stabilizer 15 is connected to the slide rail 20 through a slider. This arrangement can ensure the stability of the tube 12 and ensure that the tube 12 can move smoothly up and down along the slider with the sampling box 3.

[0026] Furthermore, the lower end of the conduit 12 is connected to a filter head 14, and the lower end of the water intake pipe 11 is located inside the filter head 14. The function of the filter head 14 is to prevent floating objects in the water from entering the water intake pipe 11, thereby affecting the service life of the self-priming pump 6 and the final test results.

[0027] In this embodiment, a support 16 is fixedly mounted at the lower end of the conduit 12, and a water level sensor 17 is installed on the support 16 to detect the depth of the conduit 12 inserted into the water surface. In practical applications, the lifting mechanism is controlled to lift the sampling box 3 according to the detection structure of the water level sensor 17, thereby adjusting the water sampling depth. It is worth noting that the control method to achieve the above function is something that can be implemented by those skilled in the art based on common knowledge and conventional control logic. The specific control method and circuit connection are conventional technical means in this field and will not be described in detail here.

[0028] In this embodiment, an automatic cable reel 18 is provided on the supporting beam 1. The drainage hose 9 and the control cables 19 of the self-priming pump 6 and the drive element 5 are all automatically wound and unwound by the automatic cable reel 18. This avoids excessive suspension of the drainage hose 9 and control cables 19 when the sampling box 3 rises. In practical applications, the lengths of the drainage hose 9 and control cables 19 between the automatic cable reel 18 and the water sample receiving device 10 are fixed. The automatic cable reel 18 enables the winding and unwinding of the drainage hose 9 and control cables 19 between itself and the sampling box 3, adapting to the raising and lowering of the sampling box 3. Furthermore, it is easy to understand that in practical applications, the winding spool of an automatic cable reel 18 can be divided into two sections, with the control cable 19 and drainage hose 9 wound on one section respectively. Alternatively, each of the control cable 19 and drainage hose 9 can be wound and unwound using an automatic cable reel 18.

[0029] It is worth noting that the automatic reel 18, also known as an automatic reel, can be purchased directly from the market. Its working principle is to automatically wind or unwind the drain hose 9 or control cable 19 based on the tension it receives. Specifically, when the tension is greater than the preset pressure value, the automatic reel 18 unwinds; when the tension is less than the preset pressure value, the automatic reel 18 winds up. Based on this, those skilled in the art are able to select the appropriate model of automatic reel 18 to meet the above functional requirements.

[0030] In addition, the side wall of the sampling box 3 is provided with a heat dissipation window 301. The heat dissipation window 301 is designed in the form of a louver, which facilitates heat dissipation of the electrical components inside the sampling box 3 while also providing rain protection.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
