Description

[0001] This application claims priority. The application number of the prior application is 2024103382548, and the name is: Pond Aquaculture Water Quality Monitoring Buoy, and the prior application date is March 25, 2024 Technical Field

[0002] The invention relates to the technical field of water quality monitoring equipment, and in particular to an online monitoring buoy for pond aquaculture water quality. Background Art

[0003] The quality of the water environment for aquaculture is directly related to the growth and development of aquatic animals, and thus to the output, quality and economic benefits of the aquaculture industry. Therefore, water quality monitoring is required in aquaculture in order to timely control and adjust the aquaculture water quality and provide a high-quality growth water environment for aquatic products. Especially in high-density intensive farms, due to the high breeding density, the water quality deteriorates rapidly, which can easily cause irreparable and large losses. Therefore, it is necessary to monitor the water quality frequently or even in real time, and adjust the water quality in real time according to the monitoring results to reduce the breeding losses caused by the deterioration of water quality.

[0004] In current aquaculture, the traditional water quality monitoring methods are: one is to take samples at fixed points manually and analyze them offline in the laboratory; the other is to monitor them online in real time at water quality monitoring stations. The sampling laboratory analysis method requires sampling, processing and then measuring. Although the measurement results are more accurate, the processing samples are limited each time, which is time-consuming and will cause secondary pollution. The real-time online monitoring of water quality monitoring stations cannot be widely deployed over a large area due to the high cost of establishing water quality monitoring stations, the large area occupied by the monitoring stations, the fixed installation method of the monitoring equipment, the immovable installation method and the need to use mains electricity, and the monitoring locations being affected by environmental factors.

[0005] The water quality monitoring station system using the mains can only be fixed at one point for measurement. However, in the actual seawater pond aquaculture model, the water is stored in a relatively closed aquaculture pond, and the water in the aquaculture pond is kept fresh by regular water changes. This aquaculture method makes different water quality indicators at different water locations in the overall aquaculture pond, and the water quality parameters in the water body are unevenly distributed. Therefore, the measurement data of the water quality monitoring station system using the mains cannot accurately represent the overall environmental conditions of the aquaculture pond.

[0006] The Chinese utility model patent with application number 201820347822.0 proposes an aquaculture water quality monitoring device, including a detection floating platform, symmetrically arranged stable floating platforms on the left and right sides of the detection floating platform, a support baffle horizontally arranged in the inner cavity of the stable floating platform, a counterweight cavity arranged at the bottom of the support baffle, and a feed pipe connected to the counterweight cavity arranged on one side of the stable floating platform. A detection cavity is arranged at the bottom of the detection floating platform, and the induction contact rod at the bottom of the water quality detection sensor extends into the inner cavity of the detection cavity. In this technology, the weight of the device is adjusted by adding or removing counterweight raw materials to the counterweight cavity through the feed pipe, thereby adjusting the sinking depth of the detection floating platform, and further adjusting the water entry depth of the induction contact rod in the detection cavity, so as to detect water quality at different depths. However, the above-mentioned method of adjusting the water entry depth of the sensing contact rod by adjusting the weight of the device disclosed in the patent can only monitor the water quality between the sinking depth when no counterweight is added and the sinking depth when full of counterweight, and cannot monitor the water quality at a deeper sinking depth. Its monitoring range is limited, resulting in the monitoring data not being able to accurately reflect the overall water quality environment of the breeding pond. Moreover, the above-mentioned method cannot accurately control the increase or decrease of the counterweight, and cannot accurately adjust the water entry depth. In addition, the technology does not disclose how to add counterweight to the counterweight cavity through the feed pipe, nor does it disclose how to remove and reduce the counterweight, resulting in the technical personnel in this field being unable to implement the technical solution based solely on the contents recorded in its specification.

DETAILED DESCRIPTION

[0026] To facilitate understanding of the present invention, the present invention is further explained below with reference to specific embodiments in conjunction with the accompanying drawings, and the specific embodiments do not constitute a limitation on the embodiments of the present invention.

[0027] Those skilled in the art should understand that the drawings are merely schematic diagrams of embodiments, and the components in the drawings are not necessarily necessary for implementing the present invention.

[0028] In the present embodiment, a buoy for online monitoring of pond aquaculture water quality is provided, which can be connected to the ocean ranch service platform for communication, and can collect important key indicators of pond aquaculture such as pH, dissolved oxygen, salinity, temperature, etc. in real time, and transmit them wirelessly to the ocean ranch service platform, thereby realizing the monitoring and storage of real-time water quality parameter data and the query of historical data.

[0029] like Figures 1 to 5 As shown, in a specific embodiment, the pond aquaculture water quality online monitoring buoy includes a specific structure such as: a floating platform 1, a data collection box 4 is provided on the floating platform 1; a solar panel 5 is provided above the data collection box 4; a battery (not shown in the figure) is provided in the data collection box 4, and the solar panel 5 is connected to the battery; a transmitting antenna 6 is provided on the data collection box 4. In specific use, the floating platform 1 floats on the water surface to carry the various structural components thereon. The floating platform 1 can be connected to the sinking stone at the bottom of the breeding pond through an anchor rope, or the floating platform 1 can be directly connected to the bolts fixed to the bottom of the pond through a punching connection through an anchor rope, and the floating platform 1 is pulled by the anchor rope to prevent the floating platform 1 from drifting with the water flow and moving the monitoring position, so as to ensure fixed-point monitoring. The length of the anchor rope is set according to the actual situation, such as considering the depth of the breeding pond. The solar panel 5 converts solar energy into electrical energy and transmits it to the battery for storage, and the battery provides electrical energy for the data acquisition sensor, the transmitting antenna 6 and other electrical mechanisms.

[0030] In a specific embodiment, the structure of the floating platform 1 includes a floating frame composed of four hollow floating tubes 20 connected end to end in sequence through four connectors 21, the connector 21 has an internal thread, and both ends of the floating tube 20 have external threads. The threaded connection between the floating tube 20 and the connector 21 is achieved through the cooperation of the internal thread and the external thread. A support rod 22 is connected between two opposing floating tubes 20, and the data acquisition box 4 is connected to the support rod 22. In this embodiment, the number of support rods 22 is two, and in specific applications, those skilled in the art can consider the overall weight, stability, load-bearing capacity and other parameters of the equipment to specifically set the number of support rods 22.

[0031] In a specific application, the floating tube 20 and the connector 21 are made of DN110 PP material. PP is a propylene polymer that is more corrosion-resistant and acid-resistant than ordinary PVC, has high density, high buoyancy, and high stability. By setting the diameter of the floating tube 20 and the connector 21, the displacement can be changed. Those skilled in the art can set the appropriate diameter of the floating tube 20 and the connector 21 to ensure that its buoyancy can be sufficient to support the various structures thereon and will not sink into the water.

[0032] In specific applications, the support rod 22 can be made of stainless steel to reduce water corrosion and ensure service life. To reduce weight, the support rod 22 can be set to be hollow, and both ends of the support rod 22 are connected to the floating tube 20 through the clamping hoop 23. The data collection box 4 can also be made of stainless steel and welded to the support rod 22. To reduce weight, the data collection box 4 can also be made of hard plastic and connected to the support rod 22 by bolts.

[0033] In a specific embodiment, the clamping hoop 23 can be made of SUS304#120*346 t1.5 and reinforced with M6*30 bolts and nuts. The SUS304#t6 plate connects the floating tube 20 and is integrated with the end of the support rod 22, thereby increasing the overall stability of the floating platform 1.

[0034] In order to ensure that the staff can accurately judge the state of the pond water, the pond aquaculture water quality online monitoring buoy can collect water quality parameters at different depths to more comprehensively and accurately reflect the overall water quality parameters. Figure 1 As shown, in order to realize the collection of water quality parameters at different depths, a driving device (not shown in the figure) is connected below the floating platform 1, and the driving device is connected to a driving screw 7, and a mounting platform 8 is movably connected to the driving screw 7. A plurality of data acquisition sensors are arranged in the data acquisition box 4, and the sensor heads of the plurality of data acquisition sensors are all mounted on the mounting platform 8; the driving screw 7 is driven to rotate by the driving device, and the mounting platform 8 is driven to reciprocate along the driving screw 7 by the rotation of the driving screw 7, so that the sensor head on the mounting platform 8 is located at different depths.

[0035] The mounting platform 8 can be made of stainless steel. Of course, in order to reduce weight, the mounting platform 8 can be hollow, or its thickness can be reduced as much as possible, as long as the sensor head can be stably mounted.

[0036] In a specific application, the driving device (not shown in the figure) can be arranged in a mounting box 19, which is connected to the support rod 22 and is located below the data acquisition box 4. The mounting box 19 can be made of stainless steel and can be welded to the support rod 22. To reduce weight, the mounting box 19 can also be made of hard plastic and connected to the support rod 22 by bolts. The battery is electrically connected to the driving device to provide electrical energy to the driving device. For example, the driving device can be a servo motor, which is provided with electrical energy by the battery to drive the servo motor to rotate. In specific use, a plurality of the above-mentioned online monitoring buoys for pond aquaculture water quality are placed in a breeding pond, and the transmitting antenna 6 of each online monitoring buoy for pond aquaculture water quality is connected to the marine ranch service platform for communication. Each online monitoring buoy for pond aquaculture water quality has a corresponding number, and the marine ranch service platform can set a control button with a corresponding number, and send a control command through the control button. The transmitting antenna 6 receives the command and transmits it to the PLC controller in the data acquisition box 4. The PLC controller is connected to the servo motor, and controls the rotation direction, rotation speed and other parameters of the servo motor according to the control command. Alternatively, each monitoring buoy for pond aquaculture is provided with a corresponding wireless remote controller, and the staff can carry the corresponding wireless remote controller to adjust the parameter collection depth of the corresponding monitoring buoy for pond aquaculture on site.

[0037] When the parameter collection depth is adjusted, the driving device drives the driving screw 7 to rotate back and forth clockwise or counterclockwise. The reciprocating rotation of the driving screw 7 can drive the mounting platform 8 to move back and forth along the driving screw 7, so that the mounting platform 8 can be located at different depths in the water, and the sensor head on the mounting platform 8 can be located at different depths.

[0038] In order to protect the sensor head on the installation platform 8 from being damaged by aquatic organisms, impurities and sand, thereby ensuring the working stability of the sensor head and the accuracy of data collection, a cylindrical filter protection net 9 is set below the floating platform 1. Specifically, the filter protection net 9 is detachably installed at the bottom of the installation box 19, such as a folded edge is set at the top edge of the filter protection net 9, a through hole is set on the folded edge, and a through hole is set at the bottom of the corresponding installation box 19. The filter protection net 9 is detachably connected to the bottom of the installation box 19 by passing bolts through the through holes on the folded edge. Among them, the cylindrical filter protection net 9 can not only protect the sensor head, but also the provided slide groove converts the rotation of the drive screw 7 into the movement of the installation platform 8.

[0039] Furthermore, in order to realize the reciprocating movement of the mounting platform 8 along the driving screw 7 and realize the depth adjustment, a sealed bearing (not shown in the figure) is arranged at the bottom of the mounting box 19. The mounting box 19 is sealed as a whole to prevent water from entering and causing a short circuit, thereby protecting the servo motor. One end of the driving screw 7 is connected to the driving shaft of the servo motor, and the other end passes through the inner ring of the sealed bearing and extends into the filter protection net 9; two slide grooves are symmetrically arranged on the filter protection net 9, and the two slide grooves are arranged along the length direction of the filter protection net 9 and are parallel to the central axis of the driving screw 7. Correspondingly, two ear plates 10 are symmetrically arranged on both sides of the mounting platform 8, and the two ear plates 10 are respectively movably inserted into the two slide grooves. A threaded through hole is provided in the middle of the mounting platform 8, and the internal thread of the threaded through hole corresponds to the external thread of the driving screw 7. The driving screw 7 is threadedly connected to the mounting platform 8 through the threaded through hole. When the driving screw 7 rotates, the self-rotation of the driving screw 7 is converted into the axial movement of the mounting platform 8 along the driving screw 7 in cooperation with the blocking effect of the slide groove on the ear plate 10.

[0040] For example, when the servo motor drives the driving screw 7 to rotate clockwise, the mounting platform 8 moves along the driving screw 7 toward the floating platform 1. When in the water, the sensor head on the mounting platform 8 moves to the shallow water layer, moves to the depth position that needs to be monitored, and monitors the water quality parameters at the depth position; when the servo motor drives the driving screw 7 to rotate counterclockwise, the mounting platform 8 moves along the driving screw 7 toward the floating platform 1. When in the water, the sensor head on the mounting platform 8 moves to a deeper water layer, moves to the depth position that needs to be monitored, and monitors the water quality parameters at the depth position.

[0041] Furthermore, in order to ensure that the connection of the driving screw rod 7 is more stable and vertical, a bottom plate 14 is provided at the bottom of the filter protection net 9, and the bottom end of the driving screw rod 7 is rotatably connected to the bottom plate 14. Specifically, a bearing is installed on the bottom plate 14, the outer ring of the bearing is fixedly connected to the bottom plate 14, and the bottom end of the driving screw rod 7 is inserted into the inner ring of the bearing and fixedly connected to the inner ring.

[0042] However, after long-term use in the aquaculture pond, impurities in the water or microorganisms in the water are likely to remain on the filter protection net 9, thereby affecting the overall monitoring accuracy of the aquaculture pond. If microorganisms are parasitic around the filter protection net 9, the water quality parameters in the area of ​​the filter protection net 9 will be different from those in other waters that are not monitored. Therefore, the filter protection net 9 needs to be cleaned to prevent impurities or microorganisms from remaining thereon.

[0043] like Figures 3 to 5As shown, in order to clean the filter protection net 9, an integrated box 2 is connected to the bottom of the bottom plate 14 of the filter protection net 9. The integrated box 2 is cylindrical as a whole. The shell of the integrated box 2 includes an upper shell 3 and a lower shell 11. The upper shell 3 is fixedly connected to the bottom plate 14, and the lower shell 11 is connected to the upper shell 3 so that it can rotate relatively. The bottom end of the driving screw rod 7 extends into the integrated box 2, and the bottom end of the driving screw rod 7 is connected to an upper turntable 24, which can rotate with the driving screw rod 7. The edge of the lower surface of the upper turntable 24 is provided with a circle of upper annular rack 25 The inner side wall of the upper shell 3 is rotatably connected to a gear 27 meshing with the upper annular rack 25 through a connecting column 26, the middle part of the upper turntable 24 is connected to an electric-controlled telescopic device 30, and the end of the electric-controlled telescopic device 30 is rotatably connected to a lower turntable 28, and the edge of the upper surface of the lower turntable 28 is provided with a lower annular rack 29 meshing with the gear 27; the edge of the side surface of the lower turntable 28 is provided with a vertical guide groove 34 (or a slide bar), and the inner side wall of the lower shell 11 is provided with a slide bar 35 (or a guide groove) matched with the guide groove (or a slide bar), and the slide bar can slide along the guide groove in the guide groove. The electric telescopic device 30 is connected to the PLD controller, and the state of the electric telescopic device is controlled by the controller. When the electric telescopic device is in the extended state, the lower annular rack 29 is separated from the gear 27, and when the driving screw 7 rotates, the lower turntable 28 does not rotate; when the electric telescopic device is in the retracted state, the lower turntable 28 moves up to make the lower annular rack 29 mesh with the gear 27. At this time, the upper turntable 28 rotates with the driving screw 7, and the gear 27 is driven to rotate by the upper annular rack 25. The rotation of the gear 27 further drives the lower turntable 28 to rotate through the lower annular rack 29. Since the guide groove (or slide bar) on the lower turntable 28 is matched with the slide bar (or guide groove) on the lower shell, the rotation of the lower turntable 28 drives the lower shell 11 to rotate; the outer surface of the lower shell 11 is provided with a connecting rod 13, and the connecting rod 13 is connected with a cleaning wing 12 close to the filter protection net 9, and the cleaning wing 12 is as close as possible to the filter protection net 9, but does not contact. The rotation of the lower shell 11 further drives the cleaning wings 12 to rotate around the filter protection net 9 through the connecting rod 13, thereby cleaning the filter protection net 9.

[0044] In a specific application, the connecting rod is an L-shaped connecting rod, including a horizontal rod connected to the outer surface of the lower shell, and a vertical rod vertically connected to the horizontal rod, and the vertical rod is located outside the filter protection net 9. An outer sleeve can be rotatably mounted on the vertical rod of the L-shaped connecting rod, and the cleaning wing is connected to the radial end surface of the outer sleeve, so that the cleaning wing can rotate while revolving around the filter protection net, and the cleaning effect of impurities or attachments on the filter protection net 9 can be further improved. For example, end plates are arranged at the top and bottom of the vertical rod, and the outer sleeve is located between the two end plates, so that the outer sleeve can rotate on the vertical rod.

[0045] Specifically, in order to achieve a rotatable connection between the upper shell 3 and the lower shell 11, an annular guide groove 31 is set on the outer bottom edge of the upper shell 3, and then an annular guide rail 32 sliding in the annular guide groove 31 is set on the inner upper edge of the lower shell 1. The annular guide groove 31 cooperates with the annular guide rail 32 to prevent the upper shell 3 and the lower shell 11 from detaching and achieve relative rotation at the same time.

[0046] When the filter protection net 9 needs to be cleaned, the controller controls the electric control telescopic device 30 to retract, so that the lower ring rack 25 is meshed with the gear 27, and the controller controls the driving device to start, driving the driving screw 7 to rotate, thereby driving the cleaning wing 12 to rotate around the filter protection net 9 to clean it. Since the installation platform 8 will rise or fall when the driving screw 7 rotates, the driving screw 7 can use a double-threaded reciprocating screw. When the monitoring depth needs to be adjusted without cleaning the filter protection net 9, the controller controls the electric control telescopic device 30 to be in an extended state, and the lower ring rack 25 is separated from the gear 27. In this way, when the driving screw 7 rotates, the lower turntable 28 will no longer rotate. At this time, only the installation platform 8 adjusts the depth with the rotation of the driving screw 7, and the cleaning wing 12 will not rotate, and the filter protection net 9 will not be cleaned.

[0047] Specifically, the battery in the data acquisition box 4 provides power for the electric control telescopic device 30, and the electric control telescopic device 30 can be, for example, a micro electric push rod or a push-pull self-holding DC electromagnet. In order to realize the rotatable connection between the micro electric push rod or the push-pull self-holding DC electromagnet and the lower turntable 28, a blind groove 33 is provided in the middle of the lower turntable 28, and the end of the micro electric push rod or the push-pull self-holding DC electromagnet is connected to a baffle (not shown in the figure) rotating in the blind groove 33.

[0048] The rotation of the cleaning wing 12 can also stir the water area in the filter protection net 9 area to flow, forming a stirred water flow, which can clean the impurities or microorganisms hanging on the filter protection net 9. Among them, the cleaning wing 12 can be as close to the filter protection net 9 as possible, but not in contact with the filter protection net, so as to ensure a better cleaning effect without causing friction damage to the filter protection net 9. The length of the cleaning wing 12 can be set according to actual conditions, such as considering the length of the installation platform 8 to be moved in the water depth range to be monitored, and reasonably setting the length of the cleaning wing 12.

[0049] In a specific embodiment, there are two L-shaped connecting rods, which are symmetrically arranged. Each L-shaped connecting rod has a cleaning wing, and the number of cleaning wings corresponds to the number of L-shaped connecting rods. In specific applications, the number of L-shaped connecting rods is not limited to 2. Those skilled in the art can set the number of L-shaped connecting rods according to actual conditions, such as 3 or 4, or more, which are evenly arranged around the filter protection net.

[0050] In this embodiment, a lifting frame 15 is provided on the floating platform 1, and the solar panel 5 is connected to the lifting frame 15. By installing the lifting frame 15, the height of the solar panel 5 and the distance between the solar panel 5 and the data acquisition box 4 can be adjusted, so that it is convenient for the staff to open the data acquisition box 4 and install or remove the data acquisition sensor. Specifically, the lifting frame 15 includes an outer tube 16 connected to the support rod 22, and an inner tube 17 is movably inserted into the outer tube 16; the top of the inner tube 17 is connected to the solar panel 5, and a tightening bolt 18 is provided on the outer tube 16. A plurality of grooves are provided on the inner tube 17. By adjusting the height of the inner tube 17 to the desired height, the tightening bolt 18 is screwed against the groove on the outer wall of the inner tube 17, so that the inner tube is fixed at the desired height. Both the outer tube 16 and the inner tube 17 can be made of stainless steel.

[0051] In this embodiment, two lifting frames 15 are provided on both sides of the data collection box 4, that is, a lifting frame 15 is connected to both ends of each support rod 22, and a solar panel 5 is connected to the top of the lifting frame 15 on the same side. The two solar panels 5 are rotatably connected through a pivot connection, and the height of the lifting frame 15 on the same side can be adjusted separately. The solar panel 5 can have different angles to achieve the maximum utilization rate of solar energy as much as possible.

[0052] In this embodiment, the solar panel 5 adopts a resin-sealed solar cell assembly, and adopts monocrystalline silicon and polycrystalline silicon solar cell monomers. According to different application fields, it is laser cut, tandem welded and resin-encapsulated and laminated to form a component, and the size of the solar cell assembly is set appropriately according to the actual situation. This series of components has the advantages of beautiful appearance, long life, and high photoelectric conversion rate, which is both environmentally friendly and energy-saving. The solar panel and the lifting frame 15 are designed as a whole, which is convenient for disassembling and opening the data acquisition box 4 to acquire data, and avoids repeated opening and damage of the solar panel, thereby extending the service life of the solar panel. In this embodiment, the battery specification used is 12V, 7.5AH, the size is 151*65*94mm, the weight is: 2.25KG, the imported lead-tin multi-element alloy grid has a small internal resistance, corrosion resistance, can be used for long-term floating charge, and can meet the power supply of the equipment at night and on rainy days. Correspondingly, a power conversion controller is used, and the power supply is potted with imported epoxy organic silicone, which is cold-resistant, high-temperature-resistant, waterproof, and has a waterproof grade of IP67. The working efficiency is about 88%, and the outlet is protected by a sealing rubber ring.

[0053] In specific applications, multiple submersible sensors are used to collect parameters such as water temperature, dissolved oxygen, and chlorophyll in the water. Fish are most sensitive to seawater temperature. When the water temperature changes between 0.1-0.2℃, it will cause changes in fish behavior; when the dissolved oxygen is lower than 2mg / L, the fish basically stop eating, and when it is lower than 1mg / L, the fish will suffocate and die in a large area. It can be seen that dissolved oxygen has a vital impact on the growth of fish; the optimal range of water pH is 7.5~8.5, and the pH value of unpolluted seawater is between 8.0~8.3. In addition, turbidity, water level, conductivity, ammonia nitrogen, and total phosphorus content will affect aquaculture in marine ranches. In this embodiment, the more important water temperature, pH, salinity, and dissolved oxygen are selected as monitoring objects. All sensors use Global water (GW for short) series sensors, and the meter head is stainless steel 316L.

[0054] Specifically, for example, in this embodiment, a WQ401 dissolved oxygen sensor is used, which is sturdy and durable. It is connected to a ship-grade cable, and the cable length can be customized according to the monitoring depth requirements. The dissolved oxygen sensor output is a 3-wire configuration, 4-20mA, and the electronic components are completely encapsulated in a stainless steel housing using ship-grade epoxy resin. WQ401 uses a removable electrode shield and a replaceable dissolved oxygen electrode for easy maintenance. WQ401 can be connected to a GL500 data logger to record data, or it can be connected to a PC300 controller to control the start or alarm of a pump for online water quality monitoring. For example, in this embodiment, the meter head of the WQ401 dissolved oxygen sensor is installed in a data acquisition box 4, and the sensor head is installed on a mounting platform 8. A WQ-Cond-4 conductivity sensor is used, using a 4-level electrical level measurement technology to provide accurate readings of a wide range of conductivity and temperature. The built-in temperature sensor provides 2%℃ temperature compensation relative to the standard 25℃. The built-in interface module converts digital conductivity and temperature data into two independent 4-20mA signals, which are connected to the data logger and programmable logic controller (PLC) parts respectively. The meter head of the WQ-Cond-4 conductivity sensor is also installed in the data acquisition box 4, and its sensor head is installed on the mounting platform 8. The Cyclops-7 underwater fluorometer is used. The Cyclops-7 underwater fluorometer can measure a variety of fluorescent substances, including chlorophyll, phycocyanin, phycoerythrin and turbidity. It has the characteristics of high precision, low price and small size, making it widely used in marine, freshwater and dye monitoring. Although the Cyclops-7 is small in size, its sensitivity and dynamic monitoring range are not affected. It can avoid the interference of turbidity and ensure good monitoring effect under various environmental conditions. Similarly, its meter head is installed in the data acquisition box 4, and its sensor head is installed on the mounting platform 8. In this embodiment, the data acquisition box 4 can be made of a 630*530*255 polypropylene polymer combination with a waterproof grade of IP66, which has high density, high strength, and is wind and water resistant. The bottom of the data acquisition box 4 can be fixed with M6 cross countersunk self-tapping screws. The data acquisition box 4 uses a waterproof connector to connect the sensor head, and the connector is located at 2 / 3 of the height of the waterproof box to prevent water splashing. The connecting line connecting the sensor head can be an elastic connecting line, which extends into the filter protection net 9 through the through hole on the filter protection net 9 and connects to the sensor head.
