Description

Technical Field

[0001] This utility model relates to the field of water resource collection, specifically to a water collection device for a booster station in an offshore wind farm. Background Technology

[0002] As the offshore wind power industry gradually expands into deeper waters, the sea conditions will become increasingly harsh, significantly increasing the difficulty for maintenance personnel to travel to and from offshore substations. The previous short-distance, rapid travel model relying on near-shore conditions has been disrupted. Due to adverse weather and navigation safety restrictions, maintenance teams often need to be stationed at offshore substations for extended periods. While this stationing model ensures continuous monitoring and timely maintenance of equipment, it also brings new survival challenges, with freshwater shortages and transportation difficulties being particularly prominent. Therefore, there is an urgent need for a multi-source water collection device adapted to the offshore environment. This device must be capable of efficiently collecting various water sources, including rainwater, air conditioning condensate, and atmospheric moisture, to meet the daily water needs of stationed personnel and ensure emergency fire-fighting water reserves. This would completely solve the freshwater supply problem at deep-sea wind farms, providing solid logistical support for the sustainable development of the offshore wind power industry.

[0048] Preferably, the first drain pipe 6, the third drain pipe 602, and the second drain pipe 601 are all equipped with drain valves. When the device is cleaned or repaired periodically, the staff first disconnects all power and water supplies, then manually removes the top sealing covers of the water collection tank 4, the domestic water tank 13, and the fire water tank 15, and manually opens the drain valves of the first drain pipe 6, the third drain pipe 602, and the second drain pipe 601. The drain valves of the first Y-type filter 10 and the second Y-type filter 1001 are also opened. Once the water in the water collection tank 4, the domestic water tank 13, and the fire water tank 15 is basically drained, the staff can then enter the interior for cleaning or repair. After cleaning or repair, all drain valves are closed.

[0049] The diameter of the first drain pipe 6 is three times that of the inlet pipe of the water collection tank 4, so as to facilitate rapid drainage during cleaning or maintenance.

[0053] The top of the water intake pool 16 is lower than the bottom of the settling pool 1303.

[0054] The operation method of the rainwater collection device in the substation of an offshore wind farm is as follows: When it rains, the rainwater collection device 1 directs the rainwater into the fine filter device 2 for filtration. The filtered rainwater flows into the diversion device 3.

[0055] In the initial stage, when the rainfall is less than 4 mm, the rainwater contains a lot of impurities. In the diversion device 3, the collection valve 302 is closed and the diversion bucket is open.

[0056] When the rainfall is ≥4mm, the rainfall sensor 301 sends the rainfall signal to the first controller 301. The first controller 301 then sends a signal to the diversion device 3 to open the collection valve 302 and close the diversion bucket below the diversion device 3, so that the coarse filtered water enters the water collection tank 4.

[0057] When the rain sensor 301 detects that there has been no rainfall for 24 hours, the first controller 301 controls the diversion device 3 to reset to the initial state.

[0058] After the coarse filtered water enters the water collection tank 4, the first level gauge 401 transmits the water level signal in the water collection tank 4 to the second controller 403. When the first level gauge 401 detects that the water level in the water collection tank 4 is equal to 1m, the water level in the water collection tank 4 is approximately 0.8m higher than the inlet of the water pump 402. The second controller 403 first turns on the water pump 402 and the check valve 7. The water pump 402 pumps water to the first fine filtration device 11. After filtration by the first fine filtration device 11, the water flows into the inlet pipe of the activated carbon adsorption device 12. When the water level in the collection tank 4 is detected to be 0.2m, the second controller 403 shuts off the water pump 402 and the check valve 7 to prevent the water pump 402 from running dry.

[0059] Meanwhile, the water discharged from the outdoor unit 8 of the air conditioner and the dehumidifier 9 passes through the first Y-type filter 10 and the second Y-type filter 1001, flows into the second fine filtration device 1101 for filtration, and then flows into the inlet pipe of the activated carbon adsorption device 12. The second controller 403 opens the domestic water valve 702 and closes the fire water valve 701, injecting water into the domestic water tank 13. The second level gauge 1305 transmits the water level in the domestic water tank 13 to the second controller 403.

[0060] When the water level in the domestic water tank 13 reaches 3m, the second controller 403 opens the fire water valve 701 and closes the domestic water valve 702. Excess water flows into the fire water tank 15, and the ozone sterilization device 14 is activated to sterilize the water in the domestic water tank 13. The water in the fire water tank 15 is used for firefighting. If the fire water tank 15 is full, excess water is discharged directly into the sea through the first overflow pipe 501.

[0061] The ozone flow rate of the ozone sterilization device 14 can be set to 30-50 g / h. After ozone is bubbled and introduced for 45 minutes, the second controller 403 shuts off the ozone sterilization device 14 and simultaneously opens the first drain valve 1301 to inject water into the settling tank 1303 below the first drain valve 1301. If the water level in the collection tank 4 is 0.2 m at this time, the second controller 403 shuts off the water pump 402 and the check valve 7. When the water level in the collection tank 4 is 1 m, the second controller 403 reopens the water pump 402 and the check valve 7 to inject water. At the same time, the filtered water from the second fine filtration device 1101 replenishes the domestic water tank 13 through the activated carbon adsorption device 12 until the second level gauge 1305 detects that the water level in the domestic water tank 13 is 3 m. Then, the second controller 403 closes the domestic water valve 702 and opens the fire water valve 701, and the domestic water tank 13 begins the next round of sterilization and disinfection cycle.

[0062] When the second level gauge 1305 detects that the water level in the domestic water tank 13 is equal to 0.15m, the second controller 403 closes the first drain valve 1301, and simultaneously opens the domestic water valve 702, closes the fire water valve 701, and activates the ozone sterilization device 14 to refill the domestic water tank 13 for sterilization and disinfection. When the water level in the domestic water tank 13 is equal to 3m, the second controller 403 closes the domestic water valve 702 and opens the fire water valve 701.

[0063] When the sterilized water in the settling tank 1303 has been settling for 40 minutes, the second controller 403 opens the second drain valve 1304 to discharge the sterilized water to the water intake tank 16. When the third level gauge 1306 detects that the level in the settling tank 1303 is equal to 0.05m, the second controller 403 closes the second drain valve 1304.

[0064] The functions and usage of each component in the water collection device of the booster station of an offshore wind farm are as follows: Rainwater collection device 1 is fixedly welded to the underside of the eaves drainage outlet of the substation building. Rainwater collection device 1 is an open, inclined water collection trough, the structure of which is as follows: Figure 2 As shown, the tilt angle is 10°~15°, which is beneficial for accelerating rainwater collection during heavy rain. At the same time, when it rains at sea, if there is a typhoon, the wind can blow away most of the rainwater on the open tilted water collection tank, reducing part of the load on the fixed rainwater collection device 1.

[0065] The rainwater collection tank of rainwater collection device 1 is made of aluminum alloy with a fluorocarbon coating, providing double protection and excellent resistance to salt spray and corrosion, making it perfectly suited to the special marine environment of high humidity and strong corrosion. The rainwater collected by rainwater collection device 1 is introduced into the coarse filter device 2 for filtration through a corrosion-resistant PVC drainage pipe.

[0066] The first controller 301 in the diversion device 3 diverts rainwater that has been washing away the air and roof in the early stage, and the rainwater that is mixed with more dust and mud in the later stage is directed into the water collection tank 4.

[0067] The water collection tank 4 is connected to the subsequent first fine filtration device 11 through a pipeline equipped with a check valve 7. The water collection tank 4 is also equipped with an overflow pipe 5 and a sewage pipe 6.

[0068] After rainfall begins, the first controller 301 diverts the first 4mm of rainwater, and the remaining rainwater enters the collection tank.

[0069] The condensate drain pipes of the air conditioner outdoor unit 8 and the dehumidifier 9 are made of polyvinyl chloride pipes. The condensate from multiple air conditioner outdoor units 8 and dehumidifier 9 is collected into a main pipeline, which is then connected to the second fine filter device 1101.

[0070] The coarse filter device 2 is located at the inlet of the drain pipe below the rainwater collection device 1. The coarse filter device 2 uses a 50-mesh nylon filter screen to filter large particulate impurities in the rainwater. The staff cleans the filter screen every two weeks after each rain.

[0071] A first Y-type filter 10 is installed at the condensate drain outlet of the outdoor unit 8 of the air conditioner. The filter screen of the first Y-type filter 10 is made of 20-50 mesh stainless steel wire mesh. The bottom of the first Y-type filter 10 is equipped with a detachable drain valve, which allows the staff to drain the sewage once every two weeks. The operation is convenient.

[0072] The first fine filtration device 11 is made of polypropylene fiber non-woven fabric with a pore size of 5μm, which filters out tiny suspended solids and some bacteria that may be carried in the water.

[0073] The activated carbon adsorption device 12 is filled with coconut shell activated carbon with a particle size of 2-4 mm, which can powerfully remove odors and some dissolved impurities from rainwater through physical adsorption.

[0074] The domestic water tank 13 is equipped with a second level gauge 1305 and an ozone sterilization device 14. A third drain valve 602 is provided at the bottom for periodically cleaning sediment.

[0075] The domestic water tank 13 is equipped with a fire water valve 701, which transfers excess filtered water to the fire water tank 15.

[0076] This device combines the collection of rainwater and condensate, improving the water resource recycling rate and providing a continuous and stable freshwater source for the marine environment.

[0077] The first controller 301 and the rain sensor 303 can identify and discard rainwater that contains a large amount of impurities in the early stage of the flow, and accurately retain clean water sources with less dust, which not only improves the efficiency of rainwater collection, but also ensures the quality of collected water from the source.

[0078] The vent valve 1302 is used to connect the settling tank 1303 to the atmosphere. The volume of the settling tank 1303 is 4 times or more the volume of the domestic water tank 13.

[0079] The ozone sterilization device 14 can operate at an ozone flow rate of 30-50 g / h and a sterilization temperature of 15℃-28℃. After bubbling for 45 minutes, open the first drain valve 1301 to discharge the ozone into the settling tank 1303 and let it stand for one day. Then open the second drain valve 1304 to discharge the ozone into the intake tank 16 below. Nine bubbling heads of the ozone sterilization device 14 are evenly placed per square meter at the bottom of the domestic water tank 13. The domestic water tank 13 is a rectangular water tank with a square bottom and sides of 3 m * 3 m.
