Description

Technical Field

[0001] The present invention relates to the technical field of cleaning suspended matter in water meters, and particularly relates to a solar floating water meter suspended matter collection device and method. Background Art

[0002] Water area garbage generally refers to persistent, man-made or processed solid waste in the environment of rivers, lakes, seas and oceans, and its typical representative is plastic garbage floating on the water surface.

[0003] Water area garbage is seriously harmful. It will cause visual pollution to humans, reduce the value of various environmental resources, damage the ecological balance, lead to production reduction. Some plastic garbage will entangle the propellers of ships, damage the hull and machines, cause accidents and stoppages. Aquatic organisms often mistake plastic garbage for food and swallow it, cutting their organs and causing infections and deaths. Water area garbage will also entangle certain organisms, making them unable to break free, and even causing death in severe cases. Moreover, water area garbage also inhibits the photosynthesis of aquatic plants, resulting in a reduction in the available oxygen for aquatic organisms, inhibiting the activities and vitality of aquatic organisms, and destroying the balance and stability of the water area ecosystem. More seriously, water area garbage, especially plastic garbage, has entered the food chain, endangering the health and sustainable development of the water area ecosystem and even humans themselves. Especially in rivers, lakes and shallow sea areas, because they are closer to human land activities and coastal activities, the garbage density is often higher, and the impact on aquaculture, tourism, etc. is also greater.

[0004] In addition, if there are too many plants such as water algae suspended in the water meter, it is also easy to cause eutrophication of the water body.

[0005] At present, there are already widely used water meter suspended matter collection methods in inland rivers and lakes, such as professional cleaning ships, manual salvage, floating body interception, etc., but they all have disadvantages in terms of economy or functionality. And they are not fully applicable to the collection of marine water meter suspended matter, mainly for three reasons. First, the density of marine water meter suspended matter is generally less than that of inland rivers and lakes, and it is difficult to guarantee the collection efficiency. Second, the marine water conditions are complex, and higher requirements are placed on the safety and reliability of the collection ships or devices. Third, it is far from the shore and the sea area is wide, making the collection difficult and costly.

[0006] Therefore, how to solve the above problems and develop an ecological water area water meter suspended matter collection device that is widely applicable, safe and reliable, simple and efficient, cost-saving, and green and environmental protection has become an urgent problem for those skilled in the art. Summary of the Invention

[0007] In order to overcome the deficiencies of the prior art, the present invention provides a solar floating water meter suspended matter collection device and method.

[0008] To achieve the above object, the present invention adopts the following technical solutions:

[0009] In a first aspect, a solar floating water meter suspended matter collection device is provided, which includes a collection box, a photovoltaic panel assembly, columns, diagonal braces, floating barrels, floats, mooring cables and pile foundations. The collection box includes a box body with an opening at the top and a movable cover plate assembly. The movable cover plate assembly is connected to the box body, and the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body is adjustable. The box body is connected to the floating barrel and is used to suck the surface water of the water area and suspended matter of the water meter from the gap, discharge the filtered water, and leave the suspended matter of the water meter in the box body. There are multiple columns, which are spaced and connected to the floating barrel. There are multiple diagonal braces, and one end of each diagonal brace is connected to the column and the other end is connected to the floating barrel. The photovoltaic panel assembly is connected above the columns and is used to supply power to the collection box. The pile foundation is used to be vertically fixed to the bottom mud surface and extend downward. The upper end of the mooring cable is connected to the floating barrel, and the lower end is connected to the pile foundation. The float is connected to the middle of the mooring cable.

[0010] In a second aspect, a method for collecting suspended matter of a water meter is provided. Using the solar floating water meter suspended matter collection device described in the first aspect, it includes the following steps:

[0011] S1. After assembling the collection box, the photovoltaic panel assembly, the columns, the diagonal braces, and the floating barrel into an assembled body, add ballast water into the box body of the collection box, and adjust the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body to 0, so that the assembled body floats in the water, and the collection box is located below the water surface, and tow it to a predetermined position in the water area.

[0012] S2. Connect one end of the mooring cable to the pile foundation, connect the float to the middle of the mooring cable, vertically fix the pile foundation to the bottom mud surface and extend downward, and then connect the other end of the mooring cable to the floating barrel.

[0013] S3. Adjust the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body, so that the movable cover plate in the movable cover plate assembly exposes above the water surface, suck the surface water of the water area and suspended matter of the water meter from the gap, discharge the filtered water, and leave the suspended matter of the water meter in the box body, so as to collect the suspended matter of the water meter.

[0014] Through the combined action of columns, diagonal braces, pontoons, floats, mooring cables and pile foundations, the entire solar floating water meter suspended matter collection device of the present invention can be stably floating on the water surface. The collection box connected to the pontoon can suck in the surface water of the water area and suspended matter of the water meter (the suspended matter of the water meter includes, but is not limited to, water area garbage (such as wood products, glass, plastics, cigarette butts, fishing nets, etc.), oil stains, algae, etc.), discharge the filtered water, and leave the suspended matter of the water meter in the box, so as to collect the suspended matter of the water meter on the water surface. Specifically, the advantages of the embodiments of the present invention include:

[0015] (1) The present invention is applicable to the collection of suspended matter of water meters in natural water areas, including rivers, lakes and shallow seas (seas with a water depth of 5 - 15m), and has a wide range of applications.

[0016] (2) The present invention conforms to the design principle of floating engineering equipment, has a reasonable and feasible structure and excellent motion performance, and can operate safely and reliably under most water conditions.

[0017] (3) The present invention can effectively collect various suspended matter of water meters. For solid suspended matter such as water area garbage and algae, according to the maximum size of the centroid of the cut suspended matter, the present invention can collect large suspended matter with a maximum diameter of 1 meter and suspended debris with a minimum diameter of 2mm. Further, when the filter net adopts an oil-water filter net (for example, a filter net made of oil-water separation materials such as cellulose), oil stains can also be collected at the same time, and the collection range is wide.

[0018] (4) Under normal water conditions, the present invention can continuously suck in the surface water body of the water area and the suspended matter of the water meter for 24 hours a day, filter them, has a long effective working time, high collection efficiency and a large filtered water volume.

[0019] (5) The present invention has a simple structure, is easy to build, has a small drainage volume, and is easy to tow and install.

[0020] (6) The drainage volume of the present invention is much smaller than that of professional garbage cleaning boats, and the construction cost is low.

[0021] (7) When the present invention works, it is unmanned and filters at a fixed point. Compared with the professional garbage cleaning boat patrolling by boat to collect garbage, it saves a large amount of oil costs and crew costs, and has a low operation cost.

[0022] (8) The present invention converts solar energy into electric energy required for the drainage of the collection box, which is energy-saving, environmentally friendly, green and low-carbon, and solves the problem of difficult power supply on water.

[0023] (9) Further, the present invention can adjust and control the collection operation in real time by virtue of the central control system, and only needs to dispatch a boat to transfer when the collection box is full, which is safer and more intelligent than manual fishing.

[0024] (10) Further, the collection box of the present invention is detachably connected to the buoy, for example, by bolt connection. Once the collection box shows engineering aging or circuit failure, the collection box can be independently disassembled, recycled, and repaired, effectively reducing the operation and maintenance costs and improving the repair efficiency.

[0025] Generally speaking, the present invention is applicable to a wide range of waters, has a reasonable and feasible structure, excellent motion performance, realizes self-power supply, green and low-carbon by using photovoltaic panels, can work continuously for 24 hours a day, has a wide range of collection of suspended substances on the water surface, high collection efficiency, a large amount of filtered water, is easy to build, convenient for towing and installation, has low construction cost, low operation cost, and low maintenance cost, is unmanned, safe and intelligent, and provides a safer, more reliable, efficient and economical collection solution for the collection of suspended substances on the water surface of rivers, lakes and shallow seas (water depth of 5 - 15m), and is very suitable for the collection of suspended substances on the water surface of rivers, lakes and shallow seas in China and even the world.

[0033] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer.

[0034] It should be noted that the attached drawings are in a very simplified form and use non-precise scales, solely for the purpose of conveniently and clearly assisting in explaining the objectives of the embodiments of the present invention. To make the objectives, features, and advantages of the present invention more apparent and understandable, please refer to the attached drawings. It should be known that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical substantial significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the objectives that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention.

[0035] It should be noted that the orientation terms such as left, right, up, down, top, bottom, etc. in this embodiment are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive. When an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0036] As Figure 1-6 shown, in some embodiments, a solar floating water meter suspended matter collection device (hereinafter may be simply referred to as the collection device) includes a collection box 1, a photovoltaic panel assembly 2, columns 3, diagonal braces 4, floating barrels 5, floats 6, mooring cables 7, and pile foundations 8. The collection box 1 includes a box body with an opening at the top and a movable cover plate assembly. The movable cover plate assembly is connected to the box body, and the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body is adjustable. The box body is connected to the floating barrel 5 and is used to suck the surface water of the water area and the suspended matter of the water meter from the gap, discharge the filtered water, and leave the suspended matter of the water meter in the box body. There are multiple columns 3, which are spaced and connected to the floating barrel 5. There are multiple diagonal braces 4, and one end of each diagonal brace 4 is connected to the column 3, and the other end is connected to the floating barrel 5; the photovoltaic panel assembly 2 is arranged above the column 3 and is used to convert light energy into electrical energy to supply power to the collection box 1; the pile foundation 8 is used to be vertically fixed to the bottom mud surface and extend downward to play an anchoring role. The upper end of the mooring cable 7 (preferably a steel cable) is connected to the floating barrel 5 (more preferably, the upper end of the mooring cable 7 is rigidly connected to the center of the bottom of the floating barrel 5), and the lower end is connected to the pile foundation 8. The float 6 is connected to the middle of the mooring cable 7.

[0037] In a preferred embodiment, the pontoon 5 has a "field" - shaped structure (i.e., the pontoon 5 can be regarded as a structure formed by six pontoons as sides enclosing a field shape. Preferably, the lengths of the four outer sides of the pontoon 5 are 6 - 10 meters, the widths of the six sides are 0.5 - 1.5 meters, and the height is 0.3 - 1 meter; more preferably, the outer quadrilateral of the "field" - shaped structure is a square). The column 3 includes a central column and four secondary columns. The central column is rigidly connected to the center of the "field" - shaped structure (i.e., the central column is connected to the intersection point of the middle cross of the "field" - shaped structure), and the four secondary columns are respectively rigidly connected to the mid - points of the four outer sides of the "field" - shaped structure; The collection box 1 is preferably 4 or 2. As Figure 1-5 shown, when there are 4 collection boxes, the 4 collection boxes are respectively rigidly connected to the four corners of the outer quadrilateral of the "field" - shaped structure; As Figure 6 shown, when there are 2 collection boxes, the 2 collection boxes are respectively rigidly connected to two opposite corners of the outer quadrilateral of the "field" - shaped structure. In this preferred embodiment, it is a better choice that there are 5 columns (one central column and four secondary columns). If the number of columns is too many, the arrangement is dense, which is likely to cause the suspended matter of the water meter to wind around the columns and accumulate. If the number of columns is too few, it is difficult to provide a safe support for the photovoltaic panel assembly, and in order to meet the condition that the buoyancy is equal to the gravity, the diameter of the columns needs to be larger, which is likely to cause the waves to climb along the columns and hit the photovoltaic panel assembly, resulting in damage.

[0038] In the above - mentioned preferred embodiment, the pontoon 5 having a "field" - shaped structure is a better choice considering factors such as stability, economy, and safety. By contrast, the inventor also designed a pontoon as shown in Figure 7 Figure 7. This pontoon has a square structure (i.e., compared with the "field" - shaped structure in the above - mentioned embodiment, the pontoon in Figure 7 is a solid square structure formed by filling the four hollow squares of the "field" with pontoons). This kind of pontoon uses more materials, increases the cost, and is subject to greater hydrodynamic forces caused by waves and water currents. The vertical movement of the collection device is large, and it is difficult to stably collect the suspended matter of the water meter. At the same time, the inventor also designed several other structures of pontoons. For example, changing the cross in the "field" - shaped structure in the above - mentioned embodiment to a "well" - shaped structure (not shown) will use more materials and increase the cost; Another example is to remove the cross in the "field" - shaped structure in the above - mentioned embodiment and only retain the outer frame, then the collection device is prone to bending and torsion deformation.

[0039] In a preferred embodiment, as Figure 1-6 shown, four diagonal braces are evenly connected to the periphery of the lower part of the central column, and three diagonal braces are connected to the periphery of the lower part of each secondary column.

[0040] In a preferred embodiment, the height of the central column is 4 - 6 meters, and the height of the 4 secondary columns is 3 - 5 meters.

[0041] In a preferred embodiment, asFigure 1-6 As shown in the figure, the box body of the collection box 1 includes a housing 101, a waterproof partition 109, a filter screen 107, a one-way submersible pump 108, a drain port 102, a central control system 111 (i.e., the central control system), and a storage battery 110. The movable cover assembly includes a movable cover 105, a cover support 103, an upper edge connecting member 106, and a hydraulic device 104. The waterproof partition 109 is located inside the housing 101 and is used to divide the housing 101 vertically into an upper filter chamber and a lower central control system chamber. The central control system 111 and the storage battery 110 are located in the sealed and waterproof central control system chamber. The drain port 102 is provided on the housing 101. The one-way submersible pump 108 is arranged in the filter chamber and is located between the waterproof partition 109 and the filter screen 107 (in this example, the one-way submersible pump 108 is connected to the waterproof partition 109 and is located between the top surface of the waterproof partition 109 and the bottom surface of the filter screen 107). The water inlet of the one-way submersible pump 108 communicates with the water between the filter screen 107 and the waterproof partition 109 (that is, the water inlet of the one-way submersible pump 108 communicates with the water between the bottom surface of the filter screen 107 and the top surface of the waterproof partition 109). The water outlet of the one-way submersible pump 108 is used to communicate with the water outside the housing 101 through the drain port 102. One to four one-way submersible pumps can be provided, and one is provided in this example. The hydraulic device 104 is respectively connected to the movable cover 105 and the cover support 103 and is used to control the lifting of the movable cover 105, so as to adjust the height of the gap between the movable cover 105 and the upper edge of the housing 101 for the water meter suspension to flow into the filter screen 107. The upper edge connecting member 106 is detachably connected to the upper edge of the housing 101 (for example, the upper edge connecting member 106 is a square frame groove structure, and the four sides of the upper edge of the housing 101 can be correspondingly inserted into the square frame groove structure). The cover support 103 is connected to the upper edge connecting member 106. The filter screen 107 is located in the filter chamber, is connected to the upper edge connecting member 106 and is suspended below the upper edge connecting member 106. Thus, the movable cover assembly and the filter screen 107 can be used as an inner liner to be separated from or combined with the housing 101 as a whole, which is convenient for taking out or putting in the inner liner. The photovoltaic panel assembly 2 converts light energy into electrical energy and transmits it to the storage battery 110 through a circuit. The storage battery 110 is respectively electrically connected to the one-way submersible pump 108 and the central control system 111. The central control system 111 is respectively connected to the one-way submersible pump 108 and the hydraulic device 104 and is used to control the drainage rate of the one-way submersible pump 108 and the lifting of the movable cover 105 driven by the hydraulic device 104.

[0042] In a preferred embodiment, the main body shape of the collection box 1 (i.e., the outer shell 101) and the filter screen 107 are both inverted frustum pyramids, which is more convenient for the inner container to be put in and taken out. Preferably, the side length of the upper top surface of the outer shell 101 is 1 to 3 meters, the height is 1 to 3 meters, and the side length of the lower bottom surface is less than that of the upper top surface (for example, the side length of the lower bottom surface is 0.5 to 0.9 times that of the upper top surface). The upper edge connecting member 206 is a quadrilateral structure matching the quadrilateral of the upper top surface of the outer shell, and its edge width is 5 to 15 centimeters. Correspondingly, preferably, there are four cover plate support members 103. One ends of the four cover plate support members 103 are respectively rigidly connected to the hydraulic device 104, and the other ends are respectively rigidly connected to the midpoints of the four sides of the upper edge connecting member 106.

[0043] In a preferred embodiment, the photovoltaic panel assembly 2 includes a photovoltaic panel and a support structure (not shown). The support structure is respectively connected to the photovoltaic panel and the column 3. The photovoltaic panel includes four triangular photovoltaic panels 21 and four rectangular photovoltaic panels 22. The four triangular photovoltaic panels 21 are configured into a tetrahedron and connected above the central column through the support structure. The four rectangular photovoltaic panels 22 are respectively connected to the four bottom edges of the tetrahedron and respectively connected above the four secondary columns through the support structure, so that there is a photovoltaic panel 22 above the space between the collection boxes at two adjacent corners, and there is no photovoltaic panel 22 above the collection box, which is convenient for the overall movable cover plate assembly and the filter screen 107 in the collection box to be hoisted out after being separated from the outer shell 101. Preferably, the collection device further includes a plurality of upper inclined braces 9. The upper inclined braces 9 are arranged around the upper part of the column, and the two ends are respectively rigidly connected to the upper part of the column 3 and the support structure in the photovoltaic panel assembly. Preferably, the bottom side length of the tetrahedron formed by the four triangular photovoltaic panels 21 (more preferably, the four triangular photovoltaic panels 21 are of the same size) is 2 - 6 meters, and the height is 1 - 3 meters. One side length of the four rectangular photovoltaic panels 22 is the same as and coincides with the four side lengths of the bottom surface of the tetrahedron respectively, and the length of the other pair of side lengths is 2 - 5 meters.

[0044] Considering that the collection states of each collection box may be different, and situations such as excessive water intake in a certain collection box or tilting of the collection device may occur. In a preferred embodiment, a pressure sensor (each collection box corresponds to one pressure sensor) (not shown) is further provided at the bottom of the floating drum 5 corresponding to the position of the collection box 1 for monitoring the draft depth of the collection box. The pressure sensor is connected to the central control system, and the central control system is also used to monitor and regulate the collection work of each collection box in real time according to the monitoring of the pressure sensor. Due to the setting of the pressure sensor, each one-way submersible pump 108 of each collection box can be independently controlled. By controlling the drainage speed of each one-way submersible pump 108, when the collection device is collecting water surface suspended matter, it can always maintain a predetermined draft depth in the water area, and the buoyancy is always equal to the gravity, without causing the collection device to tilt or even capsize due to the different weights of the water surface suspended matter and water in each collection box.

[0045] In another specific embodiment, the present invention further provides a method for collecting suspended matter in a water meter, which uses the above-mentioned solar floating water meter suspended matter collection device and includes the following steps:

[0046] S1. After assembling the collection box, the photovoltaic panel assembly, the column, the diagonal brace, and the floating drum into an assembled body, add ballast water into the box body of the collection box, and adjust the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body to 0, so that the assembled body floats in the water, and the collection box is located below the water surface, and tow it to a predetermined position in the water area;

[0047] S2. Connect one end of the mooring cable to the pile foundation, connect the float to the middle of the mooring cable, vertically fix the pile foundation to the bottom mud surface and extend it downward, and then connect the other end of the mooring cable to the floating drum;

[0048] S3. Adjust the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body, so that the movable cover plate in the movable cover plate assembly is exposed above the water surface, suck the surface water of the water area and the suspended matter in the water meter from the gap by using the water level height difference, discharge the filtered water, and leave the suspended matter in the water meter in the box body, thereby collecting the suspended matter in the water meter.

[0049] In a preferred embodiment, in step S1, the water surface is 3 - 6 cm higher than the top surface of the collection box.

[0050] Taking Figure 1-5 the shown collection device as an example, the installation method and working principle of the collection device are as follows:

[0051] Build and assemble the collection box 1, the photovoltaic panel assembly 2, the column 3, the diagonal brace 4, and the floating drum 5 on land to obtain an assembled body. Add appropriate ballast water into the collection box 1, and press down the movable cover plate 105 to the upper top surface of the collection box 1 (that is, adjust the height of the gap between the movable cover plate in the movable cover plate assembly and the top opening of the box body to 0), so that after the above-mentioned assembled body floats in the water, the water surface is 3 - 6 cm higher than the upper top surface of the collection box 1 (that is, the top surface of the upper edge connecting member 106), and then tow it to the predetermined machine position point by a barge.

[0052] Build and assemble the float 6, the mooring cable 7, and the pile foundation 8 on land, tow them to the predetermined machine position point by a barge, use a crane to lower the pile foundation 8 to the predetermined machine position point and use a hydraulic hammer to drive the pile into the bottom of the water until it reaches the predetermined depth to complete the piling operation. Dispatch divers to connect the upper end of the mooring cable 7 to the center of the bottom of the floating drum 5, and the collection device is installed.

[0053] After installation, the central control system 111 commands the hydraulic device 104 to lift the movable cover plate 105 to expose the movable cover plate 105 above the water surface (preferably, the movable cover plate 105 is 0.5 m above the water surface). Since the water surface is 3 - 6 cm higher than the upper top surface of the collection tank 1, the surface water body of the water area and the suspended matter on the water surface will flow into the collection tank 1 through the gap between the movable cover plate 105 and the top surface of the outer shell due to the water level height difference. The suspended matter on the water surface is intercepted by the filter net 107 and stays inside the filter net 107, while the filtered water will pass through the filter net 107 and be pumped away by the unidirectional submersible pump 108, and discharged from the collection tank through the drain port 102, and flow back to water areas such as rivers, lakes and seas. Further, when the filter net 107 adopts an oil-water filter net (for example, a filter net made of oil-water separation materials such as cellulose), oil pollution can also be collected simultaneously.

[0054] In a preferred embodiment, to cope with factors such as bad water conditions, the suspended matter on the water surface gradually becomes more and heavier during the collection process, and the unidirectional submersible pump 108 may have mechanical or electrical failures, etc., the central control system 111 is also used to monitor and control the collection work in real time. When bad water conditions occur, water will flood in excessively, resulting in a sharp increase in the weight of the water in the tank. At this time, the pressure sensor (not shown) below the collection tank 1 will monitor that the draft depth of the corresponding collection tank increases sharply, and transmit this signal to the central control system 111. The central control system 111 then controls the hydraulic device 104 to extend and the movable cover plate 105 to press down, isolating the water from entering and preventing the collected suspended matter on the water surface from escaping. At the same time, the unidirectional submersible pump 108 continues to drain water until the draft depth returns to normal and then stops draining. After waiting for a period of time, the central control system 111 controls the hydraulic device 104 to contract and the movable cover plate 105 to lift. If the water conditions are normal, the device can collect normally again. If the water conditions are still bad, the above process is repeated and the movable cover plate 105 is pressed down.

[0055] In a preferred embodiment, when the unidirectional submersible pump 108 fails, the water in the tank cannot be pumped out in time and accumulates, resulting in a sharp increase in the weight of the water in the tank. The pressure sensors arranged around the bottom center of the floating drum 5 will monitor that the draft depth of the corresponding collection tank increases sharply, and this signal is transmitted to the central control system 111. The central control system 111 reports the device damage to the land general server, and at the same time controls the hydraulic device 104 to extend and the movable cover plate 105 to press down, isolating the water from entering and preventing the collected suspended matter on the water surface from escaping, and waiting for the repair ship to come for repair. When the suspended matter on the water surface in the collection tank 1 gradually becomes more and heavier during the collection process, the pressure sensor will monitor that the draft depth of the corresponding collection tank becomes slightly deeper. The central control system 111 will control to increase the drainage rate of the unidirectional submersible pump 108 and drain more water appropriately, so that the total weight of the water and the suspended matter on the water surface in the collection tank 1 is kept consistent with the original ballast water weight, ensuring that the draft depth of the collection device returns to normal.

[0056] When the collection of suspended matter in the water meter is completed or the collection device is damaged, the central control system 111 reports to the land general server, and the land dispatches an operation and maintenance ship equipped with a crane to transport the suspended matter in the water meter and repair the device. The operation and maintenance ship anchors near the device, and the crane on the ship lifts the inner tank of the collection box 1 (including the movable cover plate 105, the hydraulic device 104, the cover plate support 103, the upper edge connecting piece 106, and the filter net 107) to the ship's deck by grasping the cover plate support 103. The gripper is manipulated to tilt the inner tank of the collection box 1 so that the collected suspended matter in the water meter is poured into the garbage bin on the deck, and the filter net 107 is simply cleaned and maintained. After the operation is completed, the crane puts the inner tank of the collection box 1 back on the outer shell 101 of the collection box 1. After repeating the above operations to collect and clean all the collection boxes 1, an appropriate amount of water is poured into all the collection boxes 1 so that the water surface is 3-6 cm higher than the upper top surface of the collection box 1.
