Description

Technical Field

[0001] The invention relates to the technical field of blue algae treatment, and in particular to a blue algae salvaging ship with an adjustable salvaging range. Background Art

[0002] The main reason for the formation of cyanobacteria is eutrophication of water bodies, which is usually caused by an imbalance in the proportion of nutrients such as nitrogen and phosphorus in water bodies. Waste generated during aquaculture, industrial production, and human life is discharged into the water, which will cause a sharp increase in the content of nitrogen, phosphorus, etc. in the water body, thereby promoting the reproduction of cyanobacteria. The outbreak of cyanobacteria can cause hypoxia in water bodies, deteriorate water quality, and endanger human health. Therefore, the cleaning of cyanobacteria is very important.

[0003] In order to facilitate the cleaning of cyanobacteria, the existing technology usually uses a salvage and processing ship, which mainly includes a hull, a water pump, a filtering device and a pair of intercepting rods arranged at the bow. When the hull moves on the water surface, the intercepting rods are driven to intercept the cyanobacteria on the water surface in front of the hull, and the water pump is used to pump the cyanobacteria into the collection cabin of the hull, and the filtering equipment is used to separate the cyanobacteria and water, and finally the filtered water is discharged into the water body.

[0004] During the interception process, the interception bar of the prior art cannot adjust the interception width according to the distribution range of cyanobacteria. The cyanobacteria distributed outside the interception width are blocked by the interception bar, making it difficult for the water pump to extract them. In addition, the filtered water may contain a small amount of cyanobacteria. If it is directly discharged into the water body, the cyanobacteria will continue to multiply, reducing the efficiency of cyanobacteria treatment. Summary of the invention

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] like Figure 1 , Figure 4As shown, the present invention provides a blue algae salvaging ship with an adjustable salvage range, comprising a hull 1, an algae extraction pump 2 is installed on the hull 1, a filter chamber 3 is provided on the hull 1 near the algae extraction pump 2, an algae suction pipe 4 is installed at one end of the algae extraction pump 2, and an algae discharge pipe 5 is installed at the other end, and the end of the algae discharge pipe 5 extends into the filter chamber 3. When the algae extraction pump 2 is started, water containing blue algae is pumped into the filter chamber 3 through the algae suction pipe 4 and the algae discharge pipe 5;

[0043] A mounting platform 7 is installed on the side wall of the hull 1 near the bow, and interception rods 8 are symmetrically installed on the mounting platform 7, and a salvage area is formed between the interception rods 8;

[0044] A driving mechanism 9 is installed inside the mounting platform 7, and the driving mechanism 9 can drive the interception rod 8 to move synchronously toward or away from the central area of ​​the salvage area to adjust the range of the salvage area;

[0045] The interception rod 8 is hollow and has a spray head 13 installed equidistantly on one side thereof, the spray head 13 being parallel to the water surface, a water pump 10 being installed on the mounting platform 7, a water pumping pipe 11 being installed at one end of the water pump 10, and a drainage pipe 12 being installed at the other end, the end of the water pumping pipe 11 being connected to the filter chamber 3, and the end of the drainage pipe 12 being connected to the interior of the interception rod 8;

[0046] The water pump 10 is started and pumps the water in the filter chamber 3 to the inside of the interception rod 8 through the water pumping pipe 11 and the drainage pipe 12, and sprays the water to the salvage area through a plurality of spray heads 13 to form an inward impact force at the periphery of the salvage area.

[0047] The present invention drives the interception rod 8 to rotate through the driving mechanism 9, and adjusts the range of the salvage area according to the distribution range of the blue algae, so that all the blue algae distributed on the water surface are concentrated inside the interception rod 8, which is convenient for the algae absorption tube 4 to absorb and clean;

[0048] A spray head 13 is installed on the inner side of the interception rod 8, and the filtered water is sprayed to the inner side of the interception rod 8 through the spray head 13. On the one hand, the impact force generated by the spray head 13 when spraying water can concentrate the blue algae within the interception range of the interception rod 8 to the front of the algae absorption tube 4, so that the algae absorption tube 4 can absorb the blue algae. On the other hand, a small amount of blue algae contained in the filtered water is sprayed to the interception range of the interception rod 8 through the spray head along with the filtered water, instead of being directly discharged into the water body, so that it can be reabsorbed and filtered, thereby improving the efficiency of blue algae treatment.

[0049] like Figure 4As shown, the driving mechanism 9 is installed inside the mounting platform 7, and is used to drive the two intercepting rods 8 to rotate around the algae absorption port of the algae absorption tube 4, and utilize the rotation action of the intercepting rod 8 to intercept the blue algae on the water surface to the front of the algae absorption tube 4. In order to facilitate the driving mechanism 9 to drive the intercepting rod 8 to rotate, the driving mechanism 9 includes a first driving motor 901 installed in the mounting platform 7, a fan gear 902 connected to the end of the intercepting rod 8, and a connecting shaft 903. The end of the first driving motor 901 is symmetrically installed with a driving shaft 904, and the driving shaft 904 is provided with an external thread. A circular through hole is opened at the end of the intercepting rod 8, and the connecting shaft 903 passes through the circular through hole, and both ends are installed on the inner wall of the mounting platform 7. The end of the intercepting rod 8 The part is rotatably installed in the mounting platform 7 through the connecting shaft 903, and the driving shaft 904 is driven to rotate by the first driving motor 901, and the intercepting rod 8 is driven to rotate around the connecting shaft 903 through the fan gear 902. When the intercepting rod 8 intercepts, it swings about 90° from the two sides of the hull 1 to the front of the hull 1. The arc length of the fan gear 902 can control the rotation angle of the intercepting rod 8, and the driving shaft 904 can control the rotation direction of the intercepting rod 8. The fan gear 902 cooperates with the external thread on the driving shaft 902, which can not only control the rotation angle of the intercepting rod 8, but also make the two intercepting rods 8 rotate with the connecting shaft 903 as the center, and at the same time, toward or away from the center of the salvage range.

[0050] The algae discharge pipe 5 discharges the mixture of blue algae and water into the filter chamber 3, and the water and blue algae are filtered and separated through the filter chamber 3. The separated blue algae need to be transported out of the filter chamber 3 so that the filter chamber 3 can continue to filter the subsequently discharged mixture. In order to enable the filter chamber 3 to not only transport the separated blue algae out but also separate the blue algae from water, a conveyor belt 6 is installed in the filter chamber 3. The algae discharge port of the algae discharge pipe 5 is located above the conveyor belt 6. The mixture is discharged onto the conveyor belt 6 through the algae discharge pipe 5. The water in the mixture flows to the bottom of the filter chamber 3 through the rotating conveyor belt 6. The blue algae in the mixture is transported to the next process through the rotating conveyor belt 6, thereby separating the blue algae from water and transporting the blue algae out of the filter chamber 3.

[0051] If the algae discharge pipe 5 has only one algae discharge port, all the mixed materials can only be piled up on a part of the conveyor belt 6 after flowing out of the algae discharge port, which not only makes the other transport parts of the conveyor belt 6 ineffective, but also the mixed materials piled together cannot be separated and filtered well. In order to make the mixed materials fall onto the conveyor belt 6 as separated as possible, the algae discharge port of the algae discharge pipe 5 is designed to be Y-shaped. In this way, there are two algae discharge ports, so that the mixed materials can be divided into two piles and fall onto the conveyor belt 6, and the Y-shaped algae discharge port design avoids clogging of the mixed materials.

[0052] like Figure 3As shown, the cyanobacteria in the water body are initially filtered by the filter chamber 3 and then transported to the next process. In order to facilitate storage in the next process, a collecting chamber 15 is provided on the hull 1. The collecting chamber 15 and the filter chamber 3 are arranged side by side along the length direction of the hull 1. The filtered cyanobacteria are transported from the filter chamber 3 to the collecting chamber 15. In order to facilitate transportation, a conveyor belt 6 is provided between the collecting chamber 15 and the filter chamber 3. The feeding end of the conveyor belt 6 is aligned with the end of the algae discharge pipe 5, and the feeding end thereof is aligned with the opening of the collecting chamber 15. A plurality of filter holes are provided on the conveyor belt 6. The filtered cyanobacteria are transported to the collecting chamber 15 through the conveyor belt 6. As the cyanobacteria are transported upward, most of the water in the cyanobacteria flows to the bottom of the filter chamber 3 along the inclined conveyor belt 6 under the action of gravity, and a small part of the water drips from the filter holes on the conveyor belt 6 into the filter chamber 3, thereby realizing the separation of the cyanobacteria from the water while transporting the cyanobacteria.

[0053] The cyanobacteria after the initial filtration by the conveyor belt 6 still contain some water. With the accumulation of cyanobacteria in the collecting chamber 15, the water in the collecting chamber 15 will gradually increase, resulting in the water in the collecting chamber 15 occupying part of the load of the hull 1, and thus failing to carry as much cyanobacteria as possible. In order to filter the water in the cyanobacteria in the collecting chamber 15, a vibration column 16 is installed in the collecting chamber 15, and a filter screen 17 is installed above the vibration column 16. The cyanobacteria after the initial filtration are transported to the collecting chamber 5 via the conveyor belt 6 and fall onto the filter screen 17. The vibration of the vibration column 16 at the bottom of the filter screen 17 shakes the water in the cyanobacteria to the bottom of the collecting chamber 15. In order to discharge the water at the bottom of the collecting chamber 15, a second through hole 18 is opened between the collecting chamber 15 and the bottom of the filter chamber 3. The collecting chamber 15 is connected to the filter chamber 3 through the second through hole 18. The water at the bottom of the collecting chamber 15 enters the filter chamber 3 through the second through hole 18, and the cyanobacteria are put into the collecting chamber 15 for temporary storage.

[0054] The mixture of water and blue algae is initially filtered by the conveyor belt 6, and then further filtered by the vibration column 16 and the filter screen 17 in the collection chamber 15, so that the blue algae and water are separated as much as possible. The separated water is pumped away by the pumping pipe 11, so that the hull 1 can carry as much blue algae as possible. At the same time, the capacity of the collection chamber 15 should be as large as possible.

[0055] like Figure 2 As shown, the water filtered in the collecting chamber 15 flows into the filter chamber 3 through the second through hole 18 and merges with the filtered water in the filter chamber 3 and is then pumped away by the pumping pipe 11. In order to facilitate the pumping pipe 11 to pump the water away, a first through hole 14 is penetrated through the cavity wall of the filter chamber 3 on the side close to the mounting platform 7. The end of the pumping pipe 11 is installed in the first through hole 14. The pumping pipe 11 pumps all the water in the filter chamber 3 through the first through hole 14, as shown in FIG. Figure 6As shown, in order to further facilitate the pumping of water by the pumping pipe 11, the bottom of the collecting chamber 15 and the bottom of the filtering chamber 3 can be designed to be inclined, wherein the height of the collecting chamber 15 on the side close to the second through hole 18 is lower than the height on the side away from the second through hole 18, the height of the filtering chamber 3 on the side close to the first through hole 14 is lower than the height on the side away from the first through hole 14, and the height of the collecting chamber 15 on the side close to the second through hole 18 is higher than or equal to the height of the filtering chamber 3 on the side close to the second through hole 18, so that the filtered water in the collecting chamber 15 can enter the filtering chamber 3 through the second through hole 18, and the water in the filtering chamber 3 can be pumped away by the pumping pipe 11 through the first through hole 14.

[0056] like Figure 5 As shown, in order to rotate the conveyor belt 6, a bracket 19 is symmetrically installed on the filter chamber 3, a roller 20 is installed at the end of the bracket 19, a second drive motor 21 is installed on the side of the bracket 19, the second drive motor 21 is connected to the end of the roller 20 through an axis, the conveyor belt 6 is sleeved on the roller 20, the roller 20 is driven to rotate by the second drive motor 21, and the roller 20 drives the conveyor belt 6 to rotate.

[0057] Since the conveyor belt 6 is inclined, and its bottom is located in the filter chamber 3, and its top is located above the collecting chamber 15, when the blue-green algae are transported to the upper half of the conveyor belt 6, the water that has not been completely filtered in the blue-green algae will drip from the conveyor belt 6 into the collecting chamber 15. In order to make the water transported to the upper half of the conveyor belt 6 for filtration drip into the filter chamber 3, a drain plate 22 is obliquely arranged between the collecting chamber 15 and the filter chamber 3 and below the conveyor belt 6. The lower end of the drain plate 22 is directly opposite to the top of the opening of the filter chamber 3. The water dripping from the upper half of the conveyor belt 6 will enter the filter chamber 3 along the drain plate 22, so that most of the water is filtered through the filter chamber 3 as much as possible, and a small part of the water is filtered through the collecting chamber 15, so as to avoid excessive water at the bottom of the collecting chamber 15 from being immersed in the filtered blue-green algae again.

[0058] Areas where blue algae reproduce seriously are usually also covered with blue algae below the water surface. In order to clean up the blue algae below the water surface, counterweight grooves 23 are opened on both sides of the filter chamber 3 along the length direction of the hull 1. Counterweight blocks 24 are arranged in the counterweight grooves 23, and the counterweight blocks 24 can roll along the length direction of the counterweight grooves 23. When dealing with areas where blue algae reproduce seriously, the counterweight blocks 24 are manually rolled along the counterweight grooves 23 toward the bow to lower the bow, so that the algae absorbing tube 4 and the intercepting rod 8 are tilted below the water surface, and the intercepting rod 8 cooperates with the algae absorbing tube 4 to clean up the blue algae below the water surface. On the other hand, as the blue algae in the collecting chamber 15 increases, the hull 1 tilts backward, which will drive the algae absorbing tube 4 and the intercepting rod 8 away from the water surface. By rolling the counterweight block 24 forward to lower the bow, the algae absorbing tube 4 and the intercepting rod 8 can be extended into the water surface to continue working.

[0059] If the algae absorbing tube 4 is directly extended into the water to absorb blue algae, larger objects such as impurities (branches, garbage) in the water will be sucked into the pipe of the algae absorbing tube 4, causing the pipe to be blocked. In order to prevent the algae absorbing tube 4 from absorbing other impurities, a fixed groove 25 is installed on the side of the mounting platform 7 away from the hull 1. A screen 26 is arranged at the front end of the fixed groove 25. The algae absorbing port of the algae absorbing tube 4 is located in the fixed groove 25. When the algae absorbing tube 4 absorbs blue algae, the screen 26 filters the larger impurities to the outside of the fixed groove 25. The mesh size of the screen 26 is adapted to the size of the blue algae, which will not affect the algae absorbing tube 4 from absorbing the blue algae.

[0060] Since the mounting platform 7, the intercepting rod 8, and the algae suction tube 4 need to be inserted into the water for operation, the water pump 10 and the first drive motor 901 also need to be inserted into the water for cooperation. In order to keep the water pump 10 and the first drive motor 901 working normally, a waterproof box 28 is installed outside the water pump 10 and the first drive motor 901. The waterproof box 28 is installed on the mounting platform 7. The waterproof box 28 can prevent water from entering the water pump 10 and the first drive motor 901, thereby destroying the internal circuit.

[0061] In order to facilitate manual control driving, a control room 29 is provided on the hull 1, and the staff controls the operation of the algae pump 2, the water pump 10, the conveyor belt 6 and other components in the control room 29. At the same time, in order to protect the personal safety of the staff, a guardrail 27 is installed around the collection chamber 15 and the hull 1 to prevent the staff from falling into the collection chamber 15 and the water.

[0062] The water pump 10 controls the water pumping pipe 11 to draw the filtered water to the drain pipe 12, and the water enters the interception rod 8 through the drain pipe 12, and is then sprayed out by several spray heads 13 on the inner side of the interception rod 8. Since there are two interception rods 8, the water sprayed by the spray heads 13 on the two interception rods 8 is all directed toward the salvage area between the interception rods 8, so that the cyanobacteria in the salvage area are subjected to lateral impact force. On the other hand, as the hull 1 moves forward, the hull 1 moves forward relative to the water surface, and the water body moves relatively toward the algae-absorbing tube 4, which also generates a thrust toward the algae-absorbing tube 4 for the cyanobacteria in the salvage area. Under the combined push of the lateral and front forces, the cyanobacteria group is prompted to move toward the position of the algae-absorbing tube 1 in an aggregated manner. At the same time, in order to connect the drain pipe 12 with the interception rod 8, an opening is opened on the interception rod 8, and the inner wall of the opening is provided with a thread. The opening is connected to the inside of the interception rod 8, and a plastic joint is installed at the end of the drain pipe 12 away from the water pump, and a thread is engraved on the outer wall of the plastic joint. The drain pipe 12 is connected to the opening by threaded matching.
