Description

Technical Field

[0001] The invention relates to the technical field of marine engineering environment restoration, in particular to an anti-fouling curtain device and its application in blocking the diffusion of marine suspended matter. Background Art

[0002] During the construction of marine engineering projects, suspended matter is easily generated during land-based construction, dredging, reef blasting, anchorage regulation, embankment engineering, mountain excavation, slope support, land formation and foundation treatment.

[0003] The current method of dealing with suspended matter is to install anti-fouling curtains in the offshore area where the project is under construction to block the spread of suspended matter.

However, during use, after seawater enters the flocculation tank, it will settle downward under the action of the flocculant, resulting in a higher floc concentration at the bottom of the flocculation tank than at the top. During the seawater mixing process, it is difficult to evenly mix the flocculant and the suspended matter, resulting in unsatisfactory purification effect and purification efficiency.

[0043] When in use, the suspended matter is blocked by the anti-fouling curtain body 1. After the traveling trolley 4 is started, it moves along the supporting track 2 and is started by the water suction pump to cooperate with the absorption tube 302 to attract the suspended matter and the seawater mixture near the anti-fouling curtain body 1 into the flocculation tank 301. In the initial state, the rotating plate 6041 remains in a horizontal state, and the electric telescopic rod 603 is in a retracted state. The lifting ring 602 and the rotating plate 6041 are located near the top of the outer frame 601. The lower pressure plate 504 is kept in an inwardly inclined state under the action of the torsion spring, which does not affect the seawater from entering the flocculation tank 301. The larger suspended blocks in the seawater cannot pass through the perforation 6042 and are blocked on the upper surface of the rotating plate 6041. After the suspended matter and the seawater mixture are transported to the flocculation tank 301, According to the amount of seawater entering the flocculation tank 301, the flocculant is introduced into the flocculation tank 301 through the flocculation container 303 to mix the flocculant with the seawater, wherein the seawater level in the flocculation tank 301 is lower than the upper surface of the extension plate 505, and then the telescopic end of the cylinder 501 moves downward to move the outer ring 503 downward to the inner side of the extension plate 505, and under the resistance of the seawater in the flocculation tank 301, the torsion spring rotates to make the oblique lower pressure plate 504 horizontal, and at the same time, the electromagnetic latch on the inner side of the lower pressure plate 504 is locked and fixed with the inner ring 502, at this time, the outer ring 503, the lower pressure plate 504 and the inner ring 502 form a closed structure, the thickness of the lower pressure plate 504 is greater than the outer ring 503, and when the lower pressure plate 504 is horizontal, the lower surface of the lower pressure plate 504 is located at the outer ring 503, and at this time, the distance between the lower surface of the lower pressure plate 504 and the lower surface of the outer ring 503 is equal to the distance between the upper surface of the outer frame 601 and the upper surface of the lifting ring 602. A pressure sensor is provided between the cylinder 501 and the inner ring 502. A pressure threshold value P1 is preset in the pressure sensor. As the cylinder 501 drives the outer ring 503, the lower pressure plate 504 and the inner ring 502 in the closed state to move downward to a preset distance, the pressure threshold value P1 is used to detect whether there is a large suspended block on the upper surface of the rotating plate 6041. When there is no large suspended block on the upper surface of the rotating plate 6041, when the cylinder 501 drives the outer ring 503, the lower pressure plate 504 and the inner ring 502 to move downward to a preset distance, the lower surface of the lower pressure plate 504 and the inner ring 502 are The upper surface of the rotating plate 6041 is in contact with the rotating plate 6041. When there are larger suspended blocks retained on the upper surface of the rotating plate 6041, when the lower pressing plate 504 approaches the rotating plate 6041, the larger suspended blocks will hinder the contact between the lower pressing plate 504 and the rotating plate 6041, and under the action of the downward pressure of the cylinder 501, the pressure threshold detected by the pressure sensor reaches P1. At this time, through the continuous downward pressure of the cylinder 501 and the extrusion force between the lower pressing plate 504 and the rotating plate 6041, the larger suspended blocks are squeezed and crushed, and the crushed suspended objects move downward through the perforation 6042. When the pressure threshold detected by the pressure sensor is lower than P1, it indicates that the crushing of the larger suspended blocks between the lower pressing plate 504 and the rotating plate 6041 is completed.

[0044] When the larger suspended blocks between the lower pressure plate 504 and the rotating plate 6041 are broken, the motor 6045 is started, and the gear 6044 and the gear ring 6046 are meshed to make the multiple rotating plates 6041 flip to an oblique state, and at the same time, the electromagnetic latch on the inner side of the lower pressure plate 504 is released from the locking fixation with the inner ring 502, and then the outer ring 503, the lower pressure plate 504 and the inner ring 502 are driven by the cylinder 501 to repeatedly and rapidly move up and down. When the cylinder 501 moves downward, the resistance of the water in the flocculation tank 301 to the lower pressure plate 504 causes the torsion spring to rotate again and remain horizontal, so that a seal is formed between the outer ring 503, the lower pressure plate 504 and the inner ring 502. As the cylinder 501 continues to extend, the outer ring 503, the lower pressure plate 504 and the inner ring 502 in the closed state squeeze the water at the bottom of the flocculation tank 301 and flow back upward through the return pipe 304. After the outer ring 503, the lower pressure plate 504 and the inner ring 502 move down to the bottom, the flocculation tank 301 is completed. 01 The bottom water body is transferred upward. During this process, the locking mechanism between the lifting ring 602 and the rotating ring 604 is disconnected. The locking mechanism is an electromagnetic lock. When the outer ring 503, the lower pressure plate 504 and the inner ring 502 in the closed state move downward, the water body passes through the gaps of multiple rotating plates 6041. The rotating connection between the lifting ring 602 and the rotating ring 604 causes the rotating plate 6041 to drive the rotating ring 604 to rotate, disturbing the water body in the flocculation tank 301 and promoting further flocculation of suspended matter in the flocculation tank 301. At the same time, the stirring blade 703 is arranged obliquely. When the water flows through the stirring blade 703, the stirring blade 703 rotates and disturbs the bottom of the aggregation cover 7 to avoid excessive aggregates at the bottom of the aggregation cover 7, ensuring smooth circulation of the water body in the flocculation tank 301. When the cylinder 501 contracts rapidly, the torsion spring keeps the tilt again through its own elastic force, and the water body located at the top of the lower pressure plate 504 flows to the bottom of the lower pressure plate 504 again, and multiple working cycles are performed in this way.

[0045] In summary, the cylinder 501 drives the outer ring 503, the lower pressure plate 504 and the inner ring 502 to move up and down repeatedly and quickly in a closed state, so that the flocculant in the flocculation tank 301 is more evenly dispersed, and at the same time, the suspended matter precipitated and accumulated at the bottom of the aggregation cover 7 can flow back upward through the return pipe 304, so that the mixing between the flocculant and the suspended matter is more sufficient, thereby improving the flocculation efficiency of the flocculant on the suspended matter.

[0046] After completing the preset number of working cycles, the cylinder 501 drives the lower outer ring 503, the lower pressure plate 504 and the inner ring 502 to move up to the initial position, and the flocculation tank 301 is allowed to stand still. The turbidity sensor in the flocculation tank 301 detects whether the suspended matter in the flocculation tank 301 has been flocculated. The flocculated matter after flocculation is deposited at the bottom of the aggregation hood 7. At this time, the drain pump on the drain pipe 704 is used to discharge the flocculated clean water. Subsequently, the sewage pump on the sewage pipe 802 is started, and the negative pressure generated by the sewage pump is used to discharge the flocculated matter at the bottom of the aggregation hood 7. The sewage pipe 802 transports the flocculated matter to the coast through the connecting pipe, and can be used as land backfill after treatment.

[0047] Example 2: Please refer to Figures 1 to 8 In actual use, when the concentration of suspended matter in the flocculation tank 301 is high, large floccules will quickly form at the bottom of the aggregation cover 7. The formation of large floccules not only affects the flow of water through the hollow structure of the aggregation cover 7, but also causes small particles of suspended matter to be covered under the large floccules, resulting in a decrease in the overall flocculation efficiency of the suspended matter. In this regard, the following embodiment 2 is provided to improve the above problem:

[0048] A flow rate sensor is provided on the top of the material receiving plate 8. When the lower outer ring 503, the lower pressure plate 504 and the inner ring 502 move up and down to make the water in the flocculation tank 301 repeatedly reflux, the flow rate state of the water at the bottom of the aggregation cover 7 is detected in real time by the flow rate sensor. When the flow rate sensor detects that the flow rate of the water at the bottom of the aggregation cover 7 is lower than the preset value V1, it indicates that a large block of flocculants has been formed at the bottom of the aggregation cover 7 and has hindered the water flow. In response to this, the lower outer ring 503, the lower pressure plate 504 and the inner ring 502 are driven by the cylinder 501 to move downward rapidly, and the upward reaction force of the gas under the lower pressure plate 504 is used to rotate the torsion spring and keep the lower pressure plate 504 horizontal. At this time, air is left under the lower pressure plate 504 and at the top of the outer frame 601. The cylinder 501 drives the lower pressure plate 504 to move downward quickly, firstly, the water between the lower pressure plate 504 and the outer frame 601 impacts the large floccules at the bottom of the gathering cover 7 in a high-pressure water flow state, and then the air between the lower pressure plate 504 and the outer frame 601 is discharged downward through the perforation 6042, so that bubbles are formed in the gathering cover 7, and some bubbles in the gathering cover 7 break the large floccules with the impact force generated by the rupture, so that the volume of the large floccules is reduced and the water flow channel is restored. At the same time, some bubbles drive the small suspended particles under the large floccules to float up, so that the small suspended particles can be fully flocculated, so as to achieve the purpose of improving the overall flocculation effect of the suspended matter, so that the flocculation tank 301 can still maintain efficient operation when treating high-concentration suspended matter.

[0049] It should be noted that when the flow sensor detects that the water flow rate at the bottom of the aggregation hood 7 has been restored, that is, when the flow sensor detects that the water flow rate at the bottom of the aggregation hood 7 has reached the preset value V1, the air between the lower pressure plate 504 and the outer frame 601 is stopped from continuing to be discharged downward through the perforation 6042 to avoid excessive impact causing excessive dispersion of suspended matter, thereby further optimizing the flocculation process and improving the stability and processing efficiency of flocculation sedimentation.

[0050] Furthermore, since the floccules are adhesive, when the sewage pipe 802 discharges the floccules outward through the sewage pump, part of the floccules will adhere to the hollow area at the bottom of the gathering cover 7 and the top of the receiving plate 8, making it difficult to drain the floccules in the hollow area and the top of the receiving plate 8, affecting the operating efficiency of the equipment in subsequent use. In this regard, the following improvements are made:

[0051] After the turbidity sensor in the flocculation tank 301 detects that the floccules in the flocculation tank 301 have completed sedimentation, or the large floccules in the above-mentioned aggregation cover 7 are broken by bubbles, and the flow rate sensor detects that the water flow rate at the bottom of the aggregation cover 7 is restored, the discharge process of the floccules inside the aggregation cover 7 is started, and the sewage pipe 802 remains open. The negative pressure continuously generated by the sewage pipe 802 is used to make the floccules that fall off from the bottom of the aggregation cover 7 and the top of the receiving plate 8 be sucked into the sewage pipe 802 and discharged outward. In this process, the flow rate sensor detects the change in the flow rate of the floccules into the sewage pipe 802. When the flow rate is When the speed sensor detects that the flow rate of the flocculants discharged outward through the sewage pipe 802 decreases again, it indicates that the filter screen in the middle of the material receiving plate 8 is blocked by the flocculants under the negative pressure of the sewage pipe 802. At this time, the electric telescopic rod 603 extends downward to make the lower sphere 7026 dock with the upper sphere 7024, and the motor 6045 drives the rotating plate 6041 to tilt. Then the cylinder 501 drives the lower pressure plate 504 to move downward. The resistance of the water body below the lower pressure plate 504 is used to keep the lower pressure plate 504 horizontal and lock it with the inner ring 502 through the electromagnetic latch. Then the cylinder 501 drives the lower pressure plate 504 to move downward. 04 is close to the top of the outer frame 601, and the cylinder 501 drives the lower pressure plate 504 to move up and down repeatedly in a short distance. When the lower pressure plate 504 moves downward, the water between the lower pressure plate 504 and the rotating plate 6041 is squeezed to flow downward. The water passes through the gap of the rotating plate 6041 to rotate the rotating ring 604 and the rotating plate 6041. The lower sphere 7026 repeatedly slides over the top of the upper sphere 7024, and the spring 7022 is repeatedly compressed and released. The rotating rod 702 and the stirring blade 703 repeatedly move up and down. When the stirring blade 703 moves downward, it impacts the receiving plate 8, and when it impacts the receiving plate 8, it produces The generated vibration is transmitted to the bottom of the gathering hood 7, and the floccules adhered to the bottom of the gathering hood 7 and the top of the receiving plate 8 are vibrated and separated. The lower pressure plate 504 is driven by the cylinder 501 to move up and down repeatedly in a short distance, so that the adhered floccules are completely removed. Under the continuous negative pressure of the sewage pipe 802, the removed floccules are quickly sucked into the sewage pipe 802 until the flow rate sensor shows that the flocculent discharge flow rate returns to normal, indicating that the filter blockage of the receiving plate 8 is unblocked and the floccules are completely cleaned. After the sewage pipe 802 is closed, each component is reset and restored to the initial state, waiting for the start of the next discharge process.
