Description

Technical Field

[0001] This utility model relates to the field of water quality monitoring technology, and more specifically, to a water quality monitoring sampler. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends to evaluate water quality. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various types of industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH value, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is some toxic substances, such as phenols, cyanides, arsenic, lead, chromium, cadmium, mercury, and organochlorine pesticides.

[0003] Existing water quality monitoring samplers are generally limited to sampling at the edges of reservoirs or rivers. Due to the limited number of sampling points, the collected water samples are not comprehensive. Furthermore, they are usually fixed at one point, making it difficult to achieve multi-point sampling; or staff have to walk to different points to collect samples, increasing the workload of the staff. Utility Model Content

The vertical pole is vertically fixed to the hull. The horizontal bar is provided with one end connected to the vertical pole and the other end extending to the outside of the hull. The lifting mechanism is connected to the horizontal bar and can reciprocate along the horizontal bar. The sampling tube is connected to the lifting mechanism, and the lifting mechanism is used to drive the sampling tube to rise and fall. The moving mechanism is provided on the horizontal bar and is used to drive the lifting mechanism to move.

[0009] Furthermore, two uprights are symmetrically arranged on the hull, and each upright is provided with a crossbar, a lifting mechanism, a sampling tube, and a moving mechanism on the side away from each other.

[0010] Furthermore, a bracket is provided at the front of the hull, and an electric pan-tilt unit is provided on the top of the bracket, with a camera mounted on the electric pan-tilt unit.

[0025] 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.

[0026] like Figure 1As shown, the water quality monitoring sampler in this embodiment includes a hull 1, uprights 2, crossbars 3, a lifting mechanism, a sampling tube 4, and a moving mechanism. The hull 1 is an electric remote-controlled boat. The uprights 2 are vertically fixed to the hull 1. The crossbar 3 is provided, with one end connected to the upright 2 and the other end extending to the outside of the hull 1. Preferably, two uprights 2 are symmetrically arranged on the hull 1, and the crossbars 3 are located on the side of the two uprights 2 that are far apart from each other. The ends of the two crossbars 3 that are far apart from the uprights 2 extend to the sides of the hull 1, respectively. The lifting mechanism is connected to the crossbar 3 and can reciprocate along the crossbar 3. The sampling tube 4 is connected to the lifting mechanism, which is used to drive the sampling tube 4 to rise and fall. The moving mechanism is provided on the crossbar 3 and is used to drive the lifting mechanism to move.

[0027] In this embodiment, combined with Figure 3 and Figure 4 As shown, the sampling cylinder 4 includes a cylinder body 401. Several partitions 402 are arranged inside the cylinder body 401, radially fixed within it. The partitions 402 divide the cylinder body 401 into several water-collecting chambers 403. A water inlet 404 corresponding to each water-collecting chamber 403 is located at the bottom of the cylinder body 401, and a solenoid valve 405 is installed at the water inlet 404. A vent pipe 406 corresponding to each water-collecting chamber 403 is located at the top of the cylinder body 401, and a one-way valve 407 is installed on the vent pipe 406. The one-way valve 407 ensures that gas or water can only flow from inside the water-collecting chamber 403 to the outside. Preferably, indicator strips corresponding to the partitions 402 are provided on the outer side and top of the cylinder body 401, facilitating observation of the distribution of the water-collecting chambers 403 inside the cylinder body 401 from outside the sampling cylinder 4. In addition, a number can be set on the outside of the cylinder 401 to facilitate marking of the water intake chamber 403 and prevent water sample confusion.

[0028] In this embodiment, as Figure 5 As shown, the lifting mechanism includes a lifting machine 5 and a connecting rope 6. The lifting machine 5 includes a lifting motor and a take-up roller. One end of the connecting rope 6 is wound around the take-up roller, and the other end is connected to the top surface of the sampling cylinder 4. The lifting motor drives the take-up roller to rotate, thereby winding or releasing the connecting rope 6, which in turn causes the sampling cylinder 4 to rise or fall.

[0029] In this embodiment, as Figure 5As shown, the moving mechanism includes a mounting plate 7, a screw 8, a drive motor 9, and a slider 10. Two mounting plates 7 are fixed to the bottom ends of the crossbar 3, and the screw 8 is positioned between the two mounting plates 7 and rotatably connected to them. The drive motor 9 is mounted on the outer side of the mounting plate 7 away from the upright 2, and its output shaft is fixedly connected to the screw 8. A slide bar 11 is provided along the length of the bottom surface of the crossbar 3. The slider 10 is fitted onto the screw 8 and screwed to it. The top surface of the slider 10 has a groove that matches the slide bar 11. The lifting machine 5 is mounted on the bottom surface of the slider 10. The drive motor 9 rotates, causing the screw 8 to rotate, thereby moving the slider 10 along the screw 8.

[0030] Specifically, the bottom surface of the slider 10 is fixed with two vertical plates, the take-up roller is set between the two vertical plates and is rotatably connected to the vertical plates, and the lifting motor is installed on the outside of one of the vertical plates and its output shaft is connected to the take-up roller.

[0031] In this embodiment, a bracket 12 is provided at the front of the hull 1, and an electric pan-tilt head 13 is provided on the top of the bracket 12. A camera 14 is mounted on the electric pan-tilt head 13, which can drive the camera 14 to adjust its angle. The electric pan-tilt head 13 is prior art, so its specific structure will not be described in detail here. A positioning module 15 is provided on the hull 1. A control module and a communication module (not shown in the figure) are provided inside the hull 1. The control module is electrically or signal-connected to the communication module, camera 14, positioning module 15, hoist 5, drive motor 9, and solenoid valve 405. The communication module is signal-connected to an external terminal, which can be a mobile phone, computer, or other device. Figure 2 As shown, a power supply compartment 16 is installed inside the hull 1, and a mobile power supply 17 is installed inside the power supply compartment 16. The mobile power supply 17 is electrically connected to the control module, communication module, camera 14, positioning module 15, hoist 5, drive motor 9, and solenoid valve 405. A compartment door 18 is installed on the top of the power supply compartment 16. The hull 1 is an electric remote-controlled boat. The electric remote-controlled boat can be controlled independently or controlled through external devices.

[0032] The vessel 1 is moved to the water surface sampling position by remote control or external device. The positioning module 15 transmits the position information to the communication module, which in turn transmits it to the external device, allowing the user to determine the sampling location. After the vessel 1 reaches the sampling position, the external device sends a command to the communication module, which then transmits the received command to the controller. The controller controls the drive motor 9 to rotate, causing the hoist 5 and sampling cylinder 4 to move to the outside of the vessel 1. The hoist motor rotates, driving the winding roller to release the connecting rope 6, causing the sampling cylinder 4 to descend into the water. Then, a command is sent again to stop the drive motor 9 and the output shaft of the hoist motor. A command is then sent to open the corresponding solenoid valve 405, allowing the water sample to enter the sampling chamber, completing the water sample collection. A command is then sent again to raise the sampling cylinder, and the vessel 1 moves to the next sampling position to continue sampling. After all samples have been collected from the sampling chamber of one sampling cylinder 4, the other sampling cylinder 4 is used for sampling.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
