Description

Technical Field

[0001] The invention relates to the technical field of water area dredging equipment, and in particular to an environmentally friendly dredging ship for purifying water quality. Background Art

[0002] The ecological function and regulatory function of the water system basin have been severely damaged by industrial development, human activities, water shortage and water pollution, resulting in polluted water bodies and even black and smelly water bodies. The black and smelly water bodies are mainly caused by lack of oxygen in the water bodies, and are also related to eutrophication and sedimentation of the water bodies. Relevant research results show that when the dissolved oxygen is as low as 2.0 mg / L, the water body will be in an oxygen-deficient state. When the dissolved oxygen is 3 mg / L to 5 mg / L, the content of organic matter and ammonia nitrogen in the water body will generally exceed the surface V class standard, showing a colored and smelly state, but there are aquatic organisms; when the dissolved oxygen is greater than 6 mg / L, the water body is in an aerobic state, the degradation rate of organic matter and ammonia nitrogen oxidation increases significantly, and the water body begins to have self-purification ability.

[0003] When water is polluted, some pollutants accumulate over time and enter the bottom mud of the water body through sedimentation or adsorption with particles. Under acidic and reducing conditions, pollutants and ammonia nitrogen are released from the bottom mud. The methane and nitrogen produced by anaerobic fermentation cause the bottom mud to float, which is also one of the important reasons for the black and smelly water.

[0004] In actual use, dredging boats are generally used to clean up the water area; dredging boats are tools for removing sediments from the bottom of the water. The power is generally a diesel engine or an electric motor. The hull is a floating body, which adopts an assembled box structure. There are dredging devices, power devices, transmission devices, etc. The dredging device is driven by power to remove sediments from the bottom of the water, and the transmission device sends them to the designated location.

[0005] The dredging boats in the prior art are mainly designed for floating objects and lack the function of purifying the bottom of the water and the water quality. In order to better realize the cleaning of the water area and the purification of the water quality, a dredging boat is developed. Summary of the invention

[0046] In order to further illustrate the present invention, the high-pressure aeration water purification system 2, the adjustable aeration system 3, the mud-water separation system 4 and the aeration output system 5 are further described below.

[0047] The structure of high pressure aeration water purification system 2 is as follows:

[0048] The high-pressure aeration water purification system 2 includes a low-pressure gas storage tank 201 for installation at the front end of the hull 1 and a high-pressure gas storage tank 202 for installation at the rear end of the hull 1. The high-pressure gas storage tank and the low-pressure gas storage tank are fixedly mounted on the hull 1 by welding. The aeration output system 5 is connected to the high-pressure gas storage tank 202. The high-pressure gas storage tank 202 and the low-pressure gas storage tank 201 are connected to each other through a pipeline 203.

[0049] A low-pressure aeration device 204 is provided on the low-pressure gas storage tank 201, and a high-pressure aeration device 205 is provided on the high-pressure gas storage tank 202. The low-pressure aeration device 204 and the high-pressure aeration device 205 both include a main pipeline 206, a branch pipe 207, a valve 213, an air pipe 209 and an aeration plate 210. The main pipeline 206 is connected to the high-pressure gas storage tank 202 or the low-pressure gas storage tank 201, a valve 213 is provided on the main pipeline 206, a plurality of branch pipes 207 are provided on the main pipeline 206, each branch pipe 207 is connected to a first valve 208, the air pipe 209 is connected to the branch pipe 207, and the aeration plate 210 is connected to the air pipe 209.

[0050] The valve 213 is a ball valve or a butterfly valve.

[0051] For further optimization, an air filter is provided between the aeration output system 5 and the high-pressure gas storage tank 202. The air can be filtered by the provided filter, thereby reducing the amount of harmful substances generated by the aeration output system 5 when compressing the air and entering the water.

[0052] The aeration plate 210 includes a bracket 211 and a nano aeration tube 212 . The nano aeration tube 212 is disposed on the bracket 211 . The aeration tube 212 is connected end to end. The aeration tube 212 is connected to the gas delivery pipe 209 .

[0053] It is further defined that the aeration tube 212 is a nano aeration tube 212; after the air is dispersed through the nano aeration tube 212, the air can enter the water more evenly, so that the air and water can be better contacted, the dissolution efficiency of oxygen in the air is improved, and the aeration time is shortened;

[0054] Furthermore, it should be noted that, in the present embodiment, the aeration pipe 212 is disposed on the bracket 211 in a spiral line manner, and the aeration pipe 212 is connected end to end, so that the aeration pipe 212 can be longer and the aeration effect is improved.

[0055] Further optimized, the bracket 211 is connected to the hull 1 through a pull rope 214, wherein a part of the air pipe 209 is connected to the buoy 215, and a plurality of first air pipes 216 are arranged on the buoy 215, and each of the first air pipes 216 is connected to an aeration plate 210.

[0056] The nano aeration tubes 212 provided in the present invention allow air to enter the water more evenly, enable better contact between air and water, improve the dissolution efficiency of oxygen in the air, and thus shorten the aeration time, quickly increase the oxygen content of the water body, and improve the underwater conditions; and, through the provided pull ropes 214, the bracket 211 can be connected to the dredging, and when the aeration plate 210 is lowered or pulled up, the air pipe 209 is prevented from being stressed, which can better protect the air pipe 209 and effectively extend the service life of the air pipe 209; by aerating the bottom of the water, the underwater environment can be effectively improved, a large amount of oxygen can be dissolved in the water, the ecological function and regulation function of the river channel can be effectively restored, and the treatment cost of the river channel can be reduced.

[0057] In this embodiment, the high-pressure gas storage tank 202 and the low-pressure gas storage tank 201 form an integrated structure with the hull 1 .

[0058] In this way, by arranging the low-pressure gas storage tank 201 and the high-pressure gas storage tank 202 at the front and rear ends of the hull 1 respectively, the buoyancy of the hull 1 can be improved, which makes it easier for the hull 1 to carry large equipment and improves the stability of the dredging ship during navigation; more importantly, the low-pressure gas storage tank 201 and the high-pressure gas storage tank 202 can also achieve the purpose of anti-collision.

[0059] The structure of the adjustable aeration system 3 is as follows:

[0060] The adjustable aeration system 3 is installed at the rear end of the hull 1 and is capable of extending into the water bottom. The aeration component 302 is installed on the hull 1 and is used to drive the aeration component 302 to rotate. The high-pressure aeration water purification system 2 is connected to the aeration component 302. The aeration component 302 includes a first steel pipe 303, a second steel pipe 304 and a connecting pipe 305. The first steel pipe 303 and the second steel pipe 304 are connected to the connecting pipe 305. The first steel pipe 303, the second steel pipe 304 and the connecting pipe 305 are connected to form a U-shaped structure. , the connecting pipe 305 is rotatably installed at the tail end of the hull; the driving component 301 includes a column 306, a pulley 307, a guide rope 308, a U-shaped connecting frame 309 and a rope winding mechanism 310, the two legs of the U-shaped connecting frame 309 are respectively hinged to the first steel pipe 303 and the second steel pipe 304, the middle part of the U-shaped connecting frame 309 is connected to the guide rope 308, the pulley 307 is installed on the column 306, the column 306 is installed on the hull 1, and the guide rope 308 is connected to the rope winding mechanism 310 installed on the column 306 after passing around the pulley 307.

[0061] In this embodiment, the connecting pipe 305 is installed on the hull 1 through the bearing seat 311.

[0062] Wherein, the connecting pipe 305 is connected to the high-pressure gas storage tank 202 .

[0063] Among them, the rope winding mechanism 310 includes a rope winding wheel, a rotating handle and a ratchet assembly. The rope winding wheel is rotatably installed on the column 306, the rotating handle is connected to the rope winding wheel, the guide rope 308 is wound around the rope winding wheel, and the ratchet assembly is arranged on the column 306 to limit the rotation of the rope winding wheel.

[0064] Thus, in actual use, the guide rope 308 can be wound by rotating the rotating handle, thereby driving the U-shaped connecting frame 309 and thus driving the aeration assembly 302 .

[0065] As an option, the rope winding mechanism 310 is a rope winding machine mounted on the column 306 .

[0066] In actual use, the hull 1 sails on the water, so that the first steel pipe 303 and the second steel pipe 304 of the aeration component 302 extend into the water bottom. The high-pressure gas is blown in by the air compressor, which can turn over the underwater sediments, such as dead leaves, so that the dead leaves on the bottom of the water can float on the water surface, which is convenient for the dredging component set on the hull 1 to salvage; at the same time, the injected high-pressure air can effectively increase the oxygen content of the water body, so that oxygen can be dissolved in the water, which can effectively restore the ecological function and regulatory function, and can effectively improve the underwater environment; through the set driving component 301, the aeration component 302 can leave the water surface when not in use, and extend into the water bottom when in use, which is more convenient to use.

[0067] After being stored in the high-pressure gas storage tank 202, the high-pressure gas output by the aeration output system 5 can be compressed to the riverbed mud layer of about 100m through the first steel pipe 303 and the second steel pipe 304. After the high-pressure gas enters the mud layer, it can instantly make the mud and rotten leaves of about square meters at the bottom float to the water surface, thereby also bringing out the dead branches and leaves deposited on the bottom of the water for many years, which is convenient for salvage and cleaning. At the same time, it is also the most important part of mobile aeration. The hull 1 realizes wandering aeration during the driving process. This method is like a rotary tiller, which tills the river bottom once, thereby achieving the purpose of improving the bottom environment of the river.

[0068] The structure of the mud-water separation system 4 is as follows:

[0069] The mud-water separation system 4 includes a stirring device arranged on the hull 1, a suction device installed on the hull 1 for sucking the mud-water mixture formed after the stirring device stirs on the bottom of the water, and a mud-water separation device installed on the hull, the mud-water separation device includes a plurality of mud-water separators 401 connected together.

[0070] The mud-water separator 401 includes a housing 402, a water inlet pipe 403 and an overflow pipe 404. The upper end of the housing 402 is a cylindrical structure, and the lower end of the housing 402 is a truncated cone structure. The upper end of the housing 402 is provided with a water inlet 405 and an overflow port 406. The overflow port 406 is located below the water inlet 405. The water inlet pipe 403 is connected to the water inlet 405, and the overflow pipe 404 is connected to the overflow port 406.

[0071] A mud discharge port 407 is provided at the lower end of the shell 402, and an adjusting device 520 for adjusting the mud discharge amount of the mud discharge port 407 is installed at the mud discharge port 407; a partition 408 is provided inside the shell 402, and the partition 408 divides the inside of the shell 402 into a first area 409 and a second area 410, the first area 409 is a mud and water deceleration area, and the second area 410 is a mud and water sedimentation area, and a water outlet 411 is provided at the middle position of the partition 408, and the first area 409 and the second area 410 are connected through the water outlet 411, the water inlet 405 is connected with the first area 409, and the overflow port 406 is connected with the second area 410, and the inner wall of the second area 410 has a guiding slope 412;

[0072] A guide plate 413 is provided inside the first region 409 . The guide plate 413 is provided on the inner wall of the first region 409 in a spiral manner.

[0073] The mud-water separator 401 is mainly composed of a housing 402, a water inlet pipe 403, an overflow pipe 404 and other components. The high-speed mud-water mixture enters the first area 409 from the water inlet pipe 403. As the mud-water mixture continues to enter the mud-water separator, the mud-water mixture will rotate in the first area 409 and achieve the purpose of deceleration under the action of the guide plate 413, and form a vortex at the center of the first area 409. At this time, suction will be formed at the water outlet 411, and the decelerated mud-water mixture will enter the second area 410 from the water outlet 411. In the second area 410, the mud and sand of the decelerated mud-water mixture will settle, and the clean water will flow out from the overflow pipe 404. The upper part of the separation device is mainly used to decelerate the water flow, and the lower part realizes mud-water separation. It has the advantages of good separation effect, simple structure, and small size.

[0074] Furthermore, the adjustment device 520 can be used to adjust the amount of mud discharged from the mud discharge port 407, thereby ensuring that the mud-water separation effect is improved when multiple mud-water separators 401 are used in combination.

[0075] Further optimization is performed, the water inlet pipe 403 and the overflow pipe 404 are connected to the outer shell 402 by welding, so that the water inlet pipe 403, the overflow pipe 404 and the outer shell 402 form an integrated structure, making the overall structure more compact.

[0076] For further optimization, the outer shell 402, the water inlet pipe 403, and the overflow pipe 404 are coated with waterproof paint, and the waterproof paint forms an anti-rust layer on the surface, which can protect them.

[0077] The regulating device 520 includes a valve 213 , and the mud discharge port 407 is provided with a mud discharge pipe, and the valve 213 is installed on the mud discharge pipe.

[0078] As an option, the regulating device 520 includes a gate plate 414, and a first mud discharge pipe 415 is connected to the mud discharge port 407. The side wall of the first mud discharge pipe 415 is provided with a socket. After the gate plate 414 is hinged on the first mud discharge pipe 415, the gate plate 414 can extend into the first mud discharge pipe 415 through the socket.

[0079] The gate plate 414 includes a handle portion 416 and a plugging portion 417 , and the cross-sectional shape of the plugging portion 417 matches the first mud discharge pipe 415 .

[0080] The gate plate 414 is hinged to the first mud discharge pipe 415 via a rotating shaft.

[0081] Thus, in actual use, the amount of mud discharge can be controlled by turning the gate plate 414 .

[0082] It should be noted that in actual use, when several mud-water separators 401 are connected together, the overflow port 406 of the previous mud-water separator 401 is connected to the water inlet 405 of the next mud-water separator 401, and the water inlet 405 of the mud-water separator 401 at the head end is connected to the suction device.

[0083] The stirring device is used to stir the bottom mud layer to form a mud-water mixture at the bottom of the water; the suction device is used to suck the mud-water mixture into the mud-water separator 401 for mud-water separation.

[0084] Thus, in actual use, the mud-water mixture will flow through each mud-water separator 401 in sequence to achieve the purpose of graded separation. In actual mud-water separation, the mud-water separation effect is better.

[0085] The stirring device and the suction device may be stirring devices and suction devices in the prior art, and only need to achieve stirring of the bottom mud layer and suction of the mud-water mixture.

[0086] In actual use, the mud-water separator 401 can be installed on the shore, and then the mud-water mixture can be sucked to the shore using the pipeline 203. After the mud-water separation, the clean water is discharged into the water bath, and the sludge can be used as fertilizer.

[0087] In this embodiment, the suction device is a submersible sand pump.

[0090] The diesel engine 501 is a six-cylinder supercharged diesel engine 501 , and the gearbox 502 is a manually adjustable gearbox 502 .

[0091] The buffer pad 508 is made of rubber material, and the thickness of the buffer pad 508 is 10-15 cm;

[0092] It is further defined that, in this embodiment, the thickness of the buffer pad 508 is 13 cm.

[0093] Among them, the blower 504 is a Roots blower 504.

[0094] In this embodiment, the output component 503 includes a mounting bracket 511, an inner pulley 512, an outer pulley 513 and a connecting shaft 514. The mounting bracket 511 is mounted on the first bracket 505, and the connecting shaft 514 is rotatably mounted on the mounting bracket 511. The inner pulley 512 is mounted on one end of the connecting shaft 514, and the outer pulley 513 is mounted on the other end.

The inner pulley 512 is connected to the input end of the blower 504 via a belt, and the diameter of the inner pulley 512 is smaller than the diameter of the outer pulley 513.

[0095] The aeration output system 5 is mainly composed of a diesel engine 501, a gearbox 502, an output assembly 503, a blower 504, a first bracket 505, a second bracket 506 and other components. In actual use, the diesel engine 501 outputs constant power, and then after the gearbox 502 adjusts the speed, the power is transmitted to the output assembly 503 through the universal connection assembly 515, and then the output assembly 503 transmits the power to the blower 504, and the blower 504 is used to provide an aeration gas source; the buffer pad 508 can play a good buffering role in actual use, and can effectively reduce the impact on the dredging ship; and the output speed is adjusted by the gearbox 502, thereby adjusting the output power of the blower 504, and the speed can be adjusted at any time according to different working conditions, thereby greatly increasing the flexibility of equipment operation.

[0096] More importantly, in the present embodiment, the gearbox 502 is connected to the output assembly 503 via a universal connection assembly 515, which can effectively separate the impact force of the diesel engine 501 and effectively extend the service life of each component; and, the inner pulley 512 is installed at one end of the connecting shaft 514, and the outer pulley 513 is installed at the other end. The end of the connecting shaft 514 on which the inner pulley 512 is installed is connected to the universal connection assembly 515, and the inner pulley 512 is connected to the input end of the blower 504 via a belt. The diameter of the inner pulley 512 is smaller than the diameter of the outer pulley 513.

[0097] After the first bracket 505 and the second bracket 506 of the present invention are connected, an L-shaped structure is formed as a whole. A fuel tank mounting bracket 509 is arranged on the first bracket 505, and a fuel tank 510 is fixedly arranged on the fuel tank mounting bracket 509. The fuel tank 510 is connected to the diesel engine 501; the universal connection assembly 514 is located below the fuel tank 510. This arrangement makes the structure of the present invention more compact and can effectively reduce its overall occupied volume.

[0098] Further optimization, in this embodiment, the first mounting rod 517 and the second mounting rod 518 are fixedly connected below the blower 504 by a first bolt 516, a slide groove 519 is provided on the second bracket 506, and bolts 516 are provided on the first mounting rod 517 and the second mounting rod 518. The bolts 516 are inserted into the slide groove 519, and the first mounting rod 517 and the second mounting rod 518 are connected to the second bracket 506 by the bolts 516.

[0099] In this way, by setting the slide groove 519, the position of the blower 504 can be easily adjusted. Since the output component 503 is connected to the power input end of the blower 504 through a belt, the belt will become loose after a long period of work, which makes it easy to adjust the preload force of the belt.

[0100] Further optimization, in this embodiment, the second mounting rod 518 is connected to an adjusting device 520, and the adjusting device 520 includes a fixing seat 521, a screw rod 522, a gasket 523 and a positioning nut 524. The fixing seat 521 is installed on the second bracket 506, and a threaded hole is provided on the fixing seat 521. One end of the screw rod 522 passes through the second mounting rod 518 and is rotatably connected to the second mounting rod 518. The other end of the screw rod 522 cooperates with the threaded hole provided on the fixing seat 521. The gasket 523 and the positioning nut 524 are located between the mounting seat and the second mounting rod 518 and are sleeved and installed on the screw rod 522.

[0101] This makes it more convenient to adjust the position of the blower 504, and it is also more convenient to adjust the preload force of the belt. In actual use, it is only necessary to loosen the connection between the first mounting rod 517 and the second mounting rod 518 and the second bracket 506. At this time, the bolts 516 provided on the first mounting rod 517 and the second mounting rod 518 can slide in the slide groove 519 to achieve the purpose of limiting the position. Then, by adjusting the screw rod 522, the second mounting rod 518 can be pulled solid to move, thereby enabling the blower 504 to move. In this way, the preload force of the belt can be adjusted, and the adjustment is simpler and more convenient.

[0102] It should be noted that, in this embodiment, the power boat provides power for the driving boat, which is used to drive the hull 1 to travel in the water.

[0103] For further optimization, in actual use, an air compressor can be installed on the hull 1, and the air compressor is connected to the high-pressure gas storage tank 202. In actual use, the high-pressure gas storage tank 202 is used in coordination with the aeration output system 5. In shallow waters, the air compressor is used to supply air, and in deep waters or when the aeration water area is large, the aeration output system 5 is used to supply air, so that the present invention can meet the requirements of different waters.

[0104] Embodiment 2

Hydraulic oil is provided in the interlayer 602.

[0106] By setting an outer protective layer 601, a sandwich layer 602 is formed between the outer protective layer 601 and the hull 1, and hydraulic oil is injected into the sandwich layer 602 to form a hydraulic shock-absorbing and anti-collision structure 6, which can effectively improve the shock-absorbing effect of the hull 1 and can effectively absorb the impact force brought by the power equipment on the hull 1 and the hull 1 during movement; a double-layer structure is formed at the bottom of the hull 1, which can make the bottom of the hull 1 have better anti-collision performance and be safer when traveling in complex waters; and the injected hydraulic oil components can play a supporting and shock-absorbing role, and can also play a prompting role. If the hull 1 is damaged after a collision, the outer protective layer 601 will be damaged first, which will protect the bottom of the hull 1, and the overflowing hydraulic oil will float on the water surface to remind the staff; the present invention has better stability when traveling and is also safer.

[0107] Embodiment 3

[0108] This embodiment is further optimized on the basis of the second embodiment. In this embodiment, the outer protective layer 601 has multiple layers, and an interlayer 602 is formed between adjacent outer protective layers 601 , and the interlayer 602 is filled with hydraulic oil.

[0109] In this way, a multi-layer buffer structure can be formed at the bottom of the hull 1 to further improve the effect of earthquake resistance and buffering. At the same time, the formed multi-layer structure can also further protect the bottom of the hull 1. It can play a role in reinforcing the bottom of the hull 11.
