Description

Technical Field

[0001] The invention belongs to the technical field of buoys, and in particular relates to a multi-parameter water quality buoy with a cleaning probe structure and a cleaning method thereof. Background Art

[0002] A water quality monitoring buoy is a technical device that uses a device floating on the surface of a water body to monitor water quality in real time. It is usually equipped with various sensors and communication modules, which can automatically collect water quality parameter data and transmit these data wirelessly to the monitoring center or the equipment of relevant managers. The basic working principle of a water quality monitoring buoy is to judge changes in water quality by continuously monitoring changes in water quality and the environment near the buoy. The buoy generally consists of two parts: a sensor and a data collector. The sensor can sense certain specific indicators of water quality in real time, such as pH value, dissolved oxygen content, etc.; and the data collector can collect the sensor's signal and process the data to form a series of numerical indicators. Conventional water quality buoys can usually collect multiple parameters in the water environment and have the characteristics of multi-parameter collection.

[0003] Conventional water quality monitoring buoys are mainly composed of buoys and sensors. Usually the sensors are installed inside the protective net at the bottom of the buoy, and the sensor probe is in contact with the water flow. Due to the complex water environment, the surface of the probe will be contaminated with silt after a long time, which will affect the accuracy of the sensor. Currently, the buoy can only be taken out and disassembled for cleaning. The overall cleaning efficiency is low and the online cleaning process cannot be achieved.

[0004] At the same time, during normal use of the water quality buoy, it is mainly protected by an external protective net to prevent the entry of impurities. However, in actual use, the protective net is prone to blockage, which will affect the water flow entering the protective net, thereby causing a decrease in the accuracy of the sensor probe data. Improvement is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a multi-parameter water quality buoy with a cleaning probe structure and a cleaning method thereof to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a multi-parameter water quality buoy with a cleaning probe structure, comprising a buoy, a device box is fixedly installed on the top of the buoy, a protective net located on the inner side of the buoy is fixedly installed on the bottom of the device box, stainless steel mounting cylinders located inside the protective net are fixedly installed on the left and right sides of the bottom of the device box, a sensor probe is installed inside the stainless steel mounting cylinder by bolts, a probe cleaning assembly is provided at the bottom of the sensor probe, an extension pipe is fixedly installed at the bottom of the probe cleaning assembly, a three-way valve is fixedly installed in the middle of the bottom of the protective net, the left and right ends of the three-way valve pass through the bottom of the protective net and are connected to the two extension pipes, an external cleaning assembly is movably installed on the outer side of the protective net, a mounting frame is fixedly installed on the outer side of the protective net near the bottom, a water inlet assembly is movably installed inside the mounting frame, the outer side of the water inlet assembly is fixedly sleeved with the external cleaning assembly, one end of the water inlet assembly close to the external cleaning assembly is connected to the input end of the three-way valve, and the output end of the sensor probe is electrically connected to the input end of the device box.

[0007] In actual use, the water quality in the aquatic environment can be monitored through the sensor probe at the bottom of the stainless steel mounting tube. The monitored data can be transmitted to the inside of the equipment box for processing and then sent remotely through the equipment box. The equipment box has built-in sensor modules, power modules, central processing units, and communication modules for processing the data collected by the sensors and sending them remotely.

[0008] As a further technical solution of the present invention, the water inlet assembly includes a water inlet tank, the middle part of which is movably connected with a main shaft, the outer side of the main shaft is movably connected to the mounting frame near the top, and the main shaft rotates relative to the mounting frame and the water inlet tank.

[0009] As a further technical solution of the present invention, the rear end of the water inlet tank is fixedly connected to a micro water pump, the front end of the water inlet tank is connected to the input end of the three-way valve, and the outer side surface of the main shaft is fixedly sleeved with a first impeller located inside the water inlet tank.

[0010] When the device needs to be cleaned, the micro water pump can be turned on to generate suction in the water body and draw water into the water inlet tank. At the same time, the water entering the water inlet tank can be pressurized and sent to the inside of the water inlet tank, and input into the inside of the three-way valve through the front end of the water inlet tank, and enter the inside of the two probe cleaning components through the extension pipe. The water entering the water inlet tank can drive the first impeller to rotate, and finally drive the main shaft to rotate, completing the power transmission.

[0011] As a further technical solution of the present invention, the probe cleaning assembly includes a power tank, the bottom end of the power tank is connected to the top end of the extension tube, and the top end of the power tank is fixedly connected to a high-pressure nozzle located directly below the sensor probe.

[0012] As a further technical solution of the present invention, a power shaft is movably connected to the middle part of the power tank, a second impeller located inside the power tank is movably sleeved on the outer side of the power shaft, a first connecting rod is fixedly connected to the front and rear sides of the power shaft, and the end of the first connecting rod away from the power shaft is movably connected to the second connecting rod through a rotating shaft.

[0013] As a further technical solution of the present invention, the probe cleaning assembly also includes a cleaning ring, which is movably sleeved on the outer side of the sensor probe, and the cleaning ring moves up and down relative to the sensor probe. The front and rear sides of the cleaning ring are movably connected to the second connecting rod.

[0014] When the detection end of the sensor probe needs to be cleaned, due to the continuous input of water flow, the high-pressure water flow can enter the interior of the power tank, and after driving the rotation of the second impeller, it is discharged through the high-pressure nozzle at the top and sprayed in a straight line to the detection end of the sensor probe, thereby cleaning the detection ends of the two sensor probes at the same time, completing the initial cleaning process.

[0015] By utilizing the water flow inside the water body, directly extracting the water flow in the water area, distributing the water flow through the water inlet assembly and the three-way valve, and pressurizing the water flow to spray it directly to the detection end of the sensor probe, the auxiliary cleaning process is completed. The entire process is completed automatically without manual disassembly and cleaning, which significantly improves the cleaning efficiency.

[0016] At the same time, when the second impeller rotates, it can drive the power shaft to rotate. At this time, the first connecting rod rotates accordingly, and drives the second connecting rod to swing. As the power shaft continues to rotate, downward pulling force and upward thrust can be applied to the cleaning ring. At this time, the cleaning ring moves up and down relative to the sensor probe, and the surface of the sensor probe can be scraped with the water flow sprayed from the bottom to complete the secondary cleaning process.

[0017] By making secondary use of the water jet, the rapid flow of high-pressure water can realize automatic cleaning of the sensor probe, and the flow of water is converted into a reciprocating movement process of the cleaning ring, and the secondary cleaning of the sensor probe surface is achieved through friction. The whole process is still completed automatically, which can significantly reduce the number of maintenance times, realize the online self-cleaning process of the device, and improve data accuracy.

[0018] As a further technical solution of the present invention, the external cleaning component includes a driving gear, which is fixedly sleeved with the outer side of the main shaft. The external cleaning component also includes a driven gear located on the outer side of the protective net, and the driven gear is movably engaged with the protective net.

[0019] As a further technical solution of the present invention, the driving gear is meshed with the driven gear, a cleaning plate is fixedly mounted on the inner side of the driven gear, and the inner side of the cleaning plate contacts the outer side of the protective net.

[0020] At the same time, when the first impeller rotates, the main shaft rotates accordingly. When the main shaft rotates, the driving gear can be driven to rotate synchronously. At this time, the driven gear on one side of the driving gear rotates accordingly, and drives the cleaning plate on the inner side to rotate circumferentially. At this time, the cleaning plate can rotate relative to the surface of the protective net to rub the surface of the protective net. At the same time, the water flow discharged from the high-pressure nozzle can clean the inside of the protective net, completing the cleaning process of the entire protective net.

[0021] By absorbing the water flow in the water body, the surface of the sensor probe can be cleaned while the surface of the protective net can be cleaned again. The whole process is completed automatically and synchronously with the cleaning of the sensor probe. It can effectively avoid the problem of clogging of the protective net and reduced internal flow during long-term use. The whole cleaning process is completed online, which further reduces the difficulty of equipment maintenance and reduces monitoring costs.

[0022] A method for cleaning a multi-parameter water quality buoy with a cleaning probe structure comprises the following steps:

[0023] S1: When the sensor probe surface is covered with a lot of impurities that affect its accuracy, the micro pump can be turned on to draw the water flow inside the water area into the water inlet tank, and then introduced into the main three-way valve after pressurization, and then input into the power tank through the extension pipe, and finally exported through the high-pressure nozzle to act on the surface of the sensor probe for preliminary cleaning;

[0024] S2: When the high-pressure water flows into the power tank, it drives the second impeller to rotate, drives the power shaft to rotate, and drives the first connecting rod and the second connecting rod to swing, and finally drives the cleaning ring to move up and down reciprocatingly, and scrapes the surface of the sensor probe with the high-pressure water flow to complete the internal cleaning process;

[0025] S3: When water flows into the water inlet tank, it can drive the first impeller to rotate, which can synchronously drive the main shaft to rotate, and finally drive the driving gear to rotate. After the speed change of the driven gear, the cleaning plate is driven to rotate circumferentially to assist in cleaning the surface of the protective net and complete the external cleaning process.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention utilizes the water flow inside the water body, directly extracts the water flow in the water area, distributes the water flow through the water inlet assembly and the three-way valve, and simultaneously pressurizes the water flow to spray directly to the detection end of the sensor probe to complete the auxiliary cleaning process. The entire process is completed automatically without manual disassembly and cleaning, which significantly improves the cleaning efficiency.

[0028] 2. The present invention makes secondary use of the water jet. The rapid flow of high-pressure water enables the sensor probe to be automatically cleaned. At the same time, the flow of water is converted into a reciprocating movement process of the cleaning ring, and the secondary cleaning of the sensor probe surface is achieved through friction. The whole process is still completed automatically, which can significantly reduce the number of maintenance times, realize the online self-cleaning process of the device, and improve data accuracy.

[0029] 3. The present invention absorbs the water flow in the water body to clean the surface of the sensor probe and clean the surface of the protective net again. The whole process is completed automatically and synchronously with the cleaning of the sensor probe, which can effectively avoid the problem of clogging of the protective net and reduced internal flow during long-term use. The whole cleaning process is completed online, which further reduces the difficulty of equipment maintenance and reduces monitoring costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] like Figure 1 and Figure 3 as well as Figure 4 As shown, the water inlet assembly 7 includes a water inlet tank 701, and the middle part of the water inlet tank 701 is movably connected with a main shaft 702, the outer side surface of the main shaft 702 is movably connected to the mounting frame 11 near the top, the main shaft 702 rotates relative to the mounting frame 11 and the water inlet tank 701, the rear end of the water inlet tank 701 is fixedly connected to a micro water pump 704, the front end of the water inlet tank 701 is connected to the input end of the three-way valve 8, and the outer side surface of the main shaft 702 is fixedly connected to a first impeller 703 located inside the water inlet tank 701.

[0043] When the device needs to be cleaned, the micro water pump 704 can be turned on to generate suction in the water body and draw water into the water inlet tank 701. At the same time, the water entering the water inlet tank 701 can be pressurized and sent to the inside of the water inlet tank 701, and input into the inside of the three-way valve 8 through the front end of the water inlet tank 701, and enter the inside of the two probe cleaning components 10 through the extension tube 9.
