Description

Technical Field

[0001] This invention relates to the field of water quality testing equipment technology, specifically to a nearshore multi-layer, multi-parameter water quality testing device. Background Technology

[0002] Currently, multi-layer seawater quality monitoring generally employs two methods. The first is the point-mounted method, where one end of a steel cable is inserted into the seawater through the sampling port of a buoy, and the other end is fixed to the buoy body. A multi-parameter water quality sensor is attached to the steel cable, and a multi-parameter water quality sensor is placed at each water depth. The sensor communicates with the data acquisition and control system via the cable. The second method uses a winch. A winch is installed on the buoy body, and the multi-parameter water quality sensor is fixed to one end of the winch and inserted into the seawater through the sampling port. Similarly, in the first method, the sensor communicates with the data acquisition and control system via the cable. When different water layers need to be measured, the winch is activated to position the multi-parameter water quality sensor at different depths.

[0003] Taking the detection of seawater at three depths as an example, method one requires three sensors, while method two requires an additional winch device and higher electrical power, both of which are quite expensive. At the same time, seawater is rich in nutrients, and marine organisms such as barnacles and oysters easily adhere to the outside of the water quality detection sensors. The blockage of the water quality detection sensors causes detection errors, and the corrosive marine environment also makes the winch prone to failure, resulting in high maintenance costs. Summary of the Invention

[0004] The purpose of this invention is to provide a nearshore multi-water-layer multi-parameter water quality detection device. It only requires one multi-parameter water quality detector to detect seawater parameters in multiple water layers. It is not only low in cost, but also solves the problem of marine organism attachment to the water quality detection sensor because the water quality detection sensor does not need to be immersed in seawater for a long time, thus reducing maintenance and increasing the service life of the water quality detection sensor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A nearshore multi-water-layer multi-parameter water quality detection device includes a control device, a power supply system, and a pumping detection device.

[0006] The power supply system is used to supply power to the control device and the pumping detection device.

[0007] The pumping detection device is electrically connected to the control device, and the control device is used at least to control the operation of the pumping detection device.

[0008] The water pumping detection device includes a container, a pump body, a multi-parameter water quality sensor, a connecting pipe, and multiple water intake pipes.

[0009] Multiple water intake pipes are connected to the container, and the multiple water intake pipes have different lengths to obtain water sources from different water layers.

[0010] The multi-parameter water quality sensor is used to detect the parameters of the water source inside the container.

[0011] One end of the connecting pipe is connected to the container, and the other end of the connecting pipe is connected to the inlet of the pump body. The connecting pipe has a branch pipe, one end of which is connected to the connecting pipe, and the other end of which is connected to the outside.

[0012] A first solenoid valve is installed on the branch pipe, and a second solenoid valve is installed on each of the multiple water intake pipes.

[0013] In at least one embodiment of the nearshore multi-water layer multi-parameter water quality detection device provided by this disclosure, the outlet of the pump body is connected to a drain pipe, and a water flow sensor is installed on the drain pipe to detect whether water flows through the drain pipe.

[0014] In at least one embodiment of the nearshore multi-layer multi-parameter water quality detection device provided in this disclosure, the power supply system includes a solar power generation system and a storage battery.

[0015] In at least one embodiment of the nearshore multi-layer multi-parameter water quality detection device provided in this disclosure, the control device is an Internet of Things (IoT) controller.

[0016] In at least one embodiment of the nearshore multi-water layer multi-parameter water quality detection device provided in this disclosure, three water intake pipes are provided.

[0017] In at least one embodiment of the nearshore multi-water layer multi-parameter water quality detection device provided by this disclosure, the multi-parameter water quality sensor is threadedly connected to the container, and the connection between the multi-parameter water quality sensor and the container is sealed.

[0018] In at least one embodiment of the nearshore multi-water-layer multi-parameter water quality detection device provided by this disclosure, the lengths of the three water intake pipes increase progressively.

[0019] In at least one embodiment of the nearshore multi-water layer multi-parameter water quality detection device provided by this disclosure, the position of the connecting pipe is higher than the position of the water intake pipe.

[0020] In at least one embodiment of the nearshore multi-water layer multi-parameter water quality detection device provided in this disclosure, the pump body is a vacuum pump.

[0021] The beneficial effects of this invention are as follows: it eliminates the need for multi-parameter water quality sensors to be placed in the corresponding water layer underwater during the detection process, solving the detection errors caused by marine organisms adhering to the sensor surface and clogging due to long-term seawater immersion. This reduces the maintenance of multi-parameter water quality sensors and extends their service life. Compared to previous detection methods, it also has the advantage of low cost.

[0026] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0027] Example like Figure 1 As shown, this embodiment provides a nearshore multi-water-layer multi-parameter water quality detection device, including a control device 10, a power supply system 20, and a pumping detection device 30.

[0028] In this embodiment, the power supply system 20 is used to supply power to the control device 10 and the pumping detection device 30; the pumping detection device 30 is electrically connected to the control device 10.

[0029] Specifically, the control device 10 adopts an Internet of Things (IoT) controller to control the operation of the multi-parameter water quality detection device, record and transmit data, and perform remote debugging and maintenance.

[0030] Specifically, the power supply system 20 consists of a solar power generation system and a storage battery.

[0031] The specific structure of the pumping detection device 30 will be further disclosed below with reference to the accompanying drawings.

[0032] like Figure 2 As shown, the water pumping detection device 30 includes a container 31, a pump body 32, a multi-parameter water quality sensor 33, a connecting pipe 34, and three water intake pipes 35. Specifically, three water intake pipes 35 are connected to the container 31 respectively. The lengths of the multiple water intake pipes 35 are different, and the lengths of the three water intake pipes 35 increase in order, so water sources from different water layers can be obtained.

[0033] Specifically, the multi-parameter water quality sensor 33 is used to detect the parameters of the water source in the container 31; the multi-parameter water quality sensor is threadedly connected to the container 31, and the connection between the multi-parameter water quality sensor and the container 31 is sealed.

[0034] Specifically, one end of the connecting pipe 34 is connected to the container 31, and the other end of the connecting pipe 34 is connected to the inlet of the pump body 32. The connecting pipe 34 has a branch pipe 36, one end of which is connected to the connecting pipe 34, and the other end of which is connected to the outside. A first solenoid valve 361 is installed on the branch pipe 36, and a second solenoid valve 351 is installed on each of the water intake pipes 35. The connecting pipe 34 is positioned higher than the water intake pipe 35.

[0035] Specifically, the outlet of the pump body 32 is connected to a drain pipe 37, and a water flow sensor 38 is installed on the drain pipe 37. The water flow sensor 38 is used to detect whether water is flowing through the drain pipe 37. The pump body 32 is a vacuum pump. The water flow sensor 38 is electrically connected to the control device 10.

[0036] The working method of the nearshore multi-water layer multi-parameter water quality detection device will be disclosed below.

[0037] When testing seawater quality, the control device opens the second solenoid valve on the water intake pipe corresponding to the water layer, keeping the water intake pipe and the container connected. Then, the vacuum pump is turned on. As the vacuum pump continues to work, the air pressure inside the container decreases and forms a negative pressure. Under negative pressure, the seawater in this water layer flows through the vacuum pump along the corresponding water intake pipe to the drain pipe. When the water flow sensor installed on the drain pipe detects water flowing through, it sends a signal to the control device. The control device then delays and shuts off the vacuum pump and the second solenoid valve on the water intake pipe to ensure that the seawater in the container is from the same water layer, thus ensuring the accuracy of the detection and keeping the seawater in the first water layer in the container. The control device controls the multi-parameter water quality sensor to detect various parameters. The control device stores the detection data locally and sends it to other remote terminals in real time. After the data detection is completed, the control device opens the second solenoid valve on the water intake pipe and the first solenoid valve on the branch pipe. After the first solenoid valve is opened, the water in the container is discharged into the seawater under the action of gravity because the container is connected to the atmosphere. The first and second solenoid valves are closed after a delay, and the water quality detection of the first water layer is completed.

[0038] Although embodiments of this application have been shown and described above, the scope of protection of this invention is not limited thereto. Any variations or substitutions that can be conceived without inventive effort should be covered within the scope of protection of this invention. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
