Description

Technical Field

[0001] This utility model relates to the field of water sampling technology, and more specifically, to a water sampling device that can be automatically adjusted. Background Technology

[0002] Water quality testing is an important means of assessing water quality, providing early warning of pollution, regulating water treatment processes, and monitoring the effectiveness of treatment. It plays a vital role in protecting water resources and human health.

[0003] To adapt to water level changes and enable automatic water intake, existing technologies typically use floats to float the sampling device, while using sampling pipes in conjunction with pumps for automatic sampling. For example, patent document CN205804478U discloses a floating water intake device. However, in existing technologies, the water intake hose not only serves as a water intake pipe but also acts as a fixation device for the water intake device. This can lead to the water intake hose being under constant stress, which can cause the connection between the water intake hose and the pump to loosen, affecting the water intake effect. Utility Model Content

[0004] The purpose of this invention is to provide an automatically adjustable water sampling device to overcome the aforementioned deficiencies of the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatically adjustable water sampling device includes a sampling box and a pumping assembly for water sampling. It also includes a water level sensor, a lifting device, a hoisting rope, a support beam, and a guide column. The support beam is fixed at the sampling point. The upper end of the guide column is fixedly connected to the support beam, and the lower end of the guide column is fixed to the bottom of the water. The sampling box is slidably mounted on the guide column. The water level sensor is located inside the sampling box to detect the water level. The lifting device is installed on the support beam and connected to the sampling box via the hoisting rope to raise or lower the sampling box according to the water level.

[0007] Optionally, the pumping assembly includes a self-priming pump, a drain hose, and a water intake pipe. The self-priming pump is located inside the sampling box. The self-priming pump draws water through the water intake pipe and delivers the water to the water sample receiving device through the drain hose.

[0008] Optionally, the pumping assembly also includes an adjusting element and a connecting hose. The connecting hose is connected between the water intake pipe and the self-priming pump. The adjusting element is located inside the sampling box and is used to drive the water intake pipe to rise and fall, thereby adjusting the water intake depth.

[0009] Optionally, the adjusting element is an electric actuator.

[0010] Optionally, a drag chain is provided between the sampling box and the supporting beam, and the control cables of the self-priming pump and the adjusting element are threaded through the drag chain.

[0011] Optionally, the sampling box includes a filter box and a housing, and the self-priming pump and the regulating element are both located inside the housing; the filter box is fixedly connected to the bottom of the housing, and the side wall of the filter box is provided with a water inlet hole, and a filter screen is provided outside the water inlet hole.

[0013] Optionally, the bottom of the sampling box is provided with a counterweight support, and several counterweight blocks are connected to the counterweight support by fasteners.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the sampling box is slidably mounted on the guide column, and its position is restricted by the guide column, which solves the problem caused by fixing the sampling box by the water intake hose in the prior art; in addition, the water level is detected by the water level sensor, and the sampling box is raised or lowered by the lifting device based on this, which can also play the role of adapting to changes in water level.

Detailed Implementation

[0018] refer to Figure 1 and Figure 2 An automatically adjustable water sampling device includes a sampling box 1 and a pumping assembly for water sampling, as well as a water level sensor 6, a lifting device 4, a hoisting rope 5, a supporting beam 2 and a guide column 3.

[0019] The supporting beam 2 is fixed at the sampling point. For example, when it is used for water sampling in the water channel 14, one end of the supporting beam 2 is anchored to one side of the water channel 14. The upper end of the guide column 3 is fixedly connected to the supporting beam 2 (preferably welded), and the lower end of the guide column 3 is anchored to the bottom of the water channel 14. The sampling box 1 is slidably set on the guide column 3. Specifically, two or more sliders 106 are set in the height direction of the sampling box 1. A slide rail is installed on the guide column 3, and the sliders 106 cooperate with the slide rail to realize the up and down sliding of the sampling box 1 along the guide column 3.

[0020] It is worth noting that the guide column 3 provides guidance for the up and down sliding of the sampling box 1, while also limiting the position of the sampling box 1. This avoids the use of a water hose to fix the sampling box 1 as in the existing technology, and solves the problem caused by fixing the sampling box 1 with a water hose in the existing technology.

[0021] A water level sensor 6 is installed inside the sampling box 1 to detect the water level. A lifting device 4 is mounted on the supporting beam 2 and connected to the sampling box 1 via a hoisting rope 5. This device raises or lowers the sampling box 1 according to the water level. Alternatively, an electric winch is preferred for the lifting device 4. In practical applications, the electric winch automatically raises or lowers the sampling device based on the detection results of the water level sensor 6, thus adapting the sampling box 1 to changes in water level. It is worth noting that the control method used to achieve this function is something that can be implemented by those skilled in the art based on common knowledge and conventional control logic. The specific control methods and circuit connections are conventional techniques in this field and will not be elaborated upon here.

[0022] The pumping assembly includes a self-priming pump 7, a drain hose 9, and a water intake pipe 8. The self-priming pump 7 is located inside the sampling box 1. The self-priming pump 7 draws water through the water intake pipe 8 and sends the water to the water sample receiving device 13 through the drain hose 9. In practical applications, the water sample receiving device 13 can only temporarily store the obtained water sample, or it can have other functions, such as water sample packaging.

[0023] In this embodiment, the pumping assembly further includes an adjusting element 11 and a connecting hose 12. The connecting hose 12 connects the water intake pipe 8 and the self-priming pump 7. The adjusting element 11 is located inside the sampling box 1 and is used to drive the water intake pipe 8 to rise and fall, thereby adjusting the water intake depth. Alternatively, the adjusting element 11 can be an electric actuator, i.e., the water intake pipe is fixedly connected to the output end of the electric actuator. When the electric actuator extends or retracts, it can drive the water intake pipe to rise and fall, thereby adjusting the water intake depth and facilitating the sampling of water at different depths within the target range, thus improving the accuracy of the final water quality test results. In addition, it should be understood that the connecting hose 12 should be of sufficient length to meet the rising and falling requirements of the water intake pipe 8.

[0024] As an alternative, a cable chain is provided between the sampling box 1 and the supporting beam 2. One end of the cable chain is fixed to the supporting beam 2, and the other end is fixed to the top of the sampling box 1 (allowing it to move up and down with the sampling box 1). The control cables 10 of the self-priming pump 7 and the adjusting element 11 are threaded through the cable chain. This arrangement prevents excessive slack in the drain hose 9 and control cable 10 when the water level rises. In other embodiments, this objective can also be achieved in other ways, such as by installing an automatic cable reel (also known as an automatic reel, which can be purchased directly from the market) on the supporting beam 2 to automatically reel in and unwind the drain hose 9 and control cable 10.

[0025] The sampling box 1 includes a filter box 103 and a housing 101. The self-priming pump 7 and the regulating element 11 are both located inside the housing 101. The housing 101 has a base 102 inside, on which the self-priming pump 7 is mounted. The regulating element 11 and the water level sensor 6 are mounted at the bottom of the housing 101 (i.e., the top of the filter box 103). The filter box 103 is fixedly connected to the bottom of the housing 101. The connection method is not limited; for example, welding or bolt connection is acceptable. The side wall of the filter box 103 has a water inlet hole, and a filter screen 1031 is provided outside the water inlet hole. The filter screen 1031 can effectively prevent floating objects in the water from entering the water intake pipe 8, thereby affecting the service life of the self-priming pump 7 and the final test results.

[0026] The side wall of the chassis 101 is provided with a heat dissipation window, which is equipped with a rainproof louver 1011; the bottom of the chassis 101 is provided with a rainproof cover 1012. This arrangement facilitates heat dissipation of electrical components (self-priming pump 7 and electric push rod) while also ensuring that the electrical components inside the chassis 101 are not affected by rainwater.

[0027] The bottom of the sampling box 1 is provided with a counterweight support 104. Several counterweight blocks 105 are connected to the counterweight support 104 by fasteners (such as bolts and screws). The counterweight can be adjusted by adding or removing counterweight blocks 105 to ensure that the sampling box 1 slides smoothly along the guide column 3.

[0028] 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.
