Description

Technical Field

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

[0002] For example, Chinese patent CN111638096A discloses an environmental monitoring water sampling device. The device uses a driving component to push the piston head to slide inside the water storage tank until the sealing ring on the piston head leaves the first through hole. Then, external water enters the water storage tank through the first through hole, and the water fills the entire water storage tank through the second through hole on the piston head, thereby realizing automatic water sampling.

[0003] However, the sampling device in the above application can only sample water from the same water layer at a time. When it is necessary to monitor and sample water quality in multiple vertical layers of water bodies, the sampling device needs to be lowered repeatedly to collect water, which is cumbersome. In addition, since there are certain impurities in the water body, if the water inlet is blocked by impurities, the sampling will fail. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a sampling device for environmental monitoring, which solves the technical problem of low efficiency caused by repeated sampling when monitoring and sampling water quality in multiple vertical layers of water bodies. It achieves the goal of sampling water quality in multiple layers of water bodies at once, thereby improving sampling efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an environmental monitoring sampling device, including a battery installed on one side of a float, a sampling mechanism for collecting water samples from different water layers on the float, and a fixed-length laying mechanism for controlling the lowering depth of the sampling mechanism on the float.

[0006] The sampling mechanism includes a sampling cylinder disposed on one side of the float, and a counterweight is installed at the bottom of the sampling cylinder. A partition plate is installed inside the sampling cylinder, and multiple water inlet pipes are installed in a ring at equal intervals at the top of the sampling cylinder. Each water inlet pipe is equipped with an electric valve. A full water alarm component is installed inside the sampling cylinder to remind users when water sampling is completed.

[0007] A further improvement is that the partition plate has a cross structure, dividing the sampling tube into four chambers, and each chamber is equipped with a corresponding water inlet pipe.

[0008] A further improvement is that the full water alarm component includes a float installed in the inner chamber of the sampling tube, and the float has multiple water inlet holes through it. Electrical contacts are installed on the top of the float and the top wall of the sampling tube respectively.

[0009] A further improvement is that a drain pipe is installed on the bottom side of the sampling cylinder corresponding to each chamber, and a sealing cap is threaded onto the drain pipe. A filter screen is installed on the top of the sampling cylinder, and a lifting ring is installed on the top of the filter screen.

[0010] A further improvement is that the controller and the battery are respectively installed in the two mounting cavities opened inside the counterweight, and the electronic components in the sampling mechanism are electrically connected to the battery, and the battery is electrically connected to the controller.

[0011] A further improvement is that the fixed-length wire feeding mechanism includes a bracket mounted on the float, and a rotating shaft is rotatably connected in a rotating hole on the bracket, and a wire feeding drum is mounted on the rotating shaft. A wire feeding motor that drives the rotating shaft to rotate and a meter counter that measures the wire feeding length of the wire feeding drum are respectively mounted on the left and right brackets.

[0012] By employing the above technical solution, this utility model provides a sampling device for environmental monitoring, which has at least the following beneficial effects:

[0013] 1. This utility model uses an external remote control to sequentially open electric valves, and introduces water of different depths into different chambers inside the sampling tube through different water inlet pipes, thereby achieving sampling of multiple layers of water at one time and improving sampling efficiency.

[0014] 2. This utility model uses a wire feeding motor to drive a rotating shaft to rotate, thereby driving the wire feeding drum to rotate and feed the wire. During the wire feeding process, a meter counter is used to accurately control the feeding depth and achieve accurate sampling.

[0015] 3. When water is normally entering through the inlet pipe, the float rises as the water level in the sampling cylinder chamber increases until the electrical contact on the float contacts the electrical contact on the top wall of the sampling cylinder and sends an electrical signal to remind the operator that sampling is complete.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] To address the inefficiency of existing technologies that require repeated sampling when monitoring and sampling water quality at multiple vertical levels, this embodiment provides a sampling device for environmental monitoring. Please refer to [reference needed]. Figures 1-5 This embodiment provides an environmental monitoring sampling device capable of sampling multiple layers of water quality simultaneously, improving sampling efficiency. The device includes a battery 2 installed on one side of a float 1. The float 1 is equipped with a sampling mechanism 3 for collecting water samples from different water layers. The float 1 also includes a fixed-length cable laying mechanism 4 for controlling the lowering depth of the sampling mechanism 3. The fixed-length cable laying mechanism 4 lowers the sampling mechanism 3 to different water quality layers, allowing for simultaneous sampling and monitoring of water from different layers.

[0032] Because existing technologies require repeated sampling when monitoring and sampling water quality in multiple vertical layers of water bodies, resulting in low efficiency, this device is equipped with a sampling mechanism 3. The sampling mechanism 3 includes a sampling cylinder 31 located on one side of the float plate 1, a counterweight 32 installed at the bottom of the sampling cylinder 31, a partition plate 33 installed inside the sampling cylinder 31, and multiple water inlet pipes 34 installed in a ring at equal intervals at the top of the sampling cylinder 31. Each water inlet pipe 34 is equipped with an electric valve 35, and a full water alarm component 36 is installed inside the sampling cylinder 31 to remind users when water sampling is completed.

[0033] The partition plate 33 has a cross structure, which divides the sampling tube 31 into four chambers, and each chamber is equipped with a corresponding water inlet pipe 34. When the sampling tube 31 is lowered to the water layer to be sampled, the electric valve 35 is opened sequentially by the external remote control, and water at different depths is introduced into different chambers in the sampling tube 31 through different water inlet pipes 34, thereby realizing sampling of multiple layers of water at one time and improving the sampling efficiency.

[0034] To prevent aquatic plants and other debris from clogging the inlet pipe 34, the device has a drain pipe 37 installed on the bottom side of the sampling tube 31 corresponding to each chamber, and a sealing cap 38 is threaded onto the drain pipe 37. A filter screen 39 is installed on the top of the sampling tube 31, and a lifting ring 310 is installed on the top of the filter screen 39. After sampling, the sealing cap 38 is unscrewed, and the water sampled at the corresponding depth is discharged into different sample tubes through the drain pipe 37. The filter screen 39 is designed to prevent aquatic plants and other debris from clogging the inlet pipe 34, which could lead to sampling failure.

[0035] The counterweight 32 has two mounting cavities, each housing a controller 311 and a battery 312. The electronic components in the sampling mechanism 3 are electrically connected to the battery 312, which in turn is electrically connected to the controller 311. The battery 312 powers the electric valve 35 and the electric contact 363, and the controller 311 and an external remote control control the opening and closing of the electric valve 35.

[0036] To more accurately control the sampling depth, the device is also equipped with a fixed-length line-laying mechanism 4. The fixed-length line-laying mechanism 4 includes a bracket 41 mounted on the float 1, and a rotating shaft 42 is rotatably connected in a rotating hole on the bracket 41. A line-laying drum 43 is mounted on the rotating shaft 42. A line-laying motor 44 that drives the rotating shaft 42 to rotate and a meter counter 45 that measures the length of the line laid by the line-laying drum 43 are respectively mounted on the left and right brackets 41. During sampling, the float 1 is placed on the water surface, and then the cable on the line-laying drum 43 is connected to the lifting ring 310. The line-laying motor 44 is controlled by an external remote control to drive the rotating shaft 42 to rotate, thereby driving the line-laying drum 43 to rotate and lay the line. During the process of the line-laying drum 43 rotating and laying the line, the meter counter 45 is used to accurately control the laying depth to achieve accurate sampling.

[0037] Example 2

[0038] Based on Example 1, such as Figures 1-5 As shown, impurities such as aquatic plants and sand may clog the inlet pipe 34 in the water, and it is impossible to directly observe whether the blockage is present, resulting in unsuccessful sampling. Therefore, the device is also equipped with a full water alarm component 36. The full water alarm component 36 includes a float 361 installed in the inner cavity of the sampling tube 31, and multiple water inlet holes 362 are opened through the float 361. Electrical contacts 363 are installed on the top of the float 361 and the top wall of the sampling tube 31 respectively. When the inlet pipe 34 is normally filled with water, the float 361 floats up as the water volume in the cavity of the sampling tube 31 rises until the electrical contacts 363 on the float 361 and the electrical contacts 363 on the top wall of the sampling tube 31 make contact and send an electrical signal to remind the operator that the sampling is complete.
