Description

Technical Field

[0001] The invention relates to a dredging ship equipment, in particular to a self-cleaning device for a traction anchor rope used in a pneumatic pump dredging ship. Background Art

[0002] As we all know, pneumatic pump dredging boats are dredging equipment widely used in underwater environmental dredging projects. They are dredging equipment that uses compressed air as a power to press out the mud that enters the pump body of the pneumatic dredging pump under the action of water level pressure difference. When the pneumatic pump dredging boat performs dredging operations, it adopts the dredging process of anchor pulling and strip-shaped partitioning construction. First, the dredging area is divided into several strips of dredging belts according to the width of the pneumatic dredging pump mud inlet, and then the traction anchor is lowered to hundreds of meters in front of the dredging boat by the anchor boat, and then the pneumatic dredging pump on the dredging boat is lowered into the silt layer at the starting dredging position of the first dredging belt through the hanger or cantilever, and then the pneumatic pump dredging boat is pulled forward by the traction anchor wire rope in front of the dredging boat. The silt at the front end of the pneumatic dredging pump enters the pump body through the mud inlet under the suction and pushing action of the pneumatic dredging pump.

[0003] The anchor wire rope is retracted and released by the anchor drum fixed on the hull deck to achieve the purpose of pulling the pneumatic pump dredging boat forward to dredge. In order to avoid the cross-entanglement of the wire rope on the drum, the anchor drum is usually arranged on the hull deck at a certain distance from the front edge of the deck. The pneumatic pump dredging boat traction anchor is stuck in the bottom mud of the water body. The anchor wire rope passes through the bottom mud, and there will always be mud hanging on the wire rope. Especially when the bottom mud of the water body is clay, large pieces of mud will stick to the wire rope. The wire rope with mud sticking to it passes through the water surface and is wound on the anchor drum above the hull deck. Part of the mud on the wire rope will fall on the hull deck as the wire rope shakes and is squeezed by the winding on the drum. The falling mud will not only cause pollution to the hull deck, affecting the neatness and beauty of the hull deck, but also easily slip and cause accidents if people step on the mud.

[0004] At present, when pneumatic pump dredging ships face the silt that falls from the anchor rope onto the deck during dredging construction, they all use water guns to wash the deck from time to time, which not only increases the labor cost and construction process, but also the hull deck is always in a state of water washing, which will increase the probability of personnel slipping and increase the possibility of accidents. Therefore, it is necessary to clean the silt on the anchor rope before it reaches the hull deck to avoid the phenomenon of silt contaminating the hull deck. Summary of the invention

[0005] The purpose of the present invention is to provide a self-cleaning device for traction anchor rope of pneumatic pump dredging ship in view of the above problems. The traction anchor rope self-cleaning device can not only automatically clean the silt stuck on the anchor rope before the anchor rope reaches the hull deck, but also blow dry the moisture stuck on the anchor rope, avoiding the pollution caused by the silt on the anchor rope falling onto the hull deck, purifying the dredging operation environment of the pneumatic pump dredging ship; eliminating the link of manual cleaning of the deck and anchor rope, simplifying the construction operation process of the pneumatic pump dredging ship; reducing the probability of personnel slipping and falling accidents, and improving the safety factor of the construction operation of the pneumatic pump dredging ship.

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] See attached Figure 1-9 The traction anchor rope self-cleaning device comprises a first roller 1 which is arranged at the front end of the hull and protrudes from the upper surface of the deck, a second roller 2 which is located near the water surface line, and a third roller 3 which is submerged in water. A scraper 5 and a brush 6 which are submerged in water are attached to the traction anchor rope 4 between the third roller 3 and the second roller 2. The underwater traction anchor rope 4 passes through the third roller 3, the scraper 5, and the brush 6 in sequence to the second roller 2, then turns upward and extends to the first roller 1, and then passes through the first roller 1 and then turns horizontally and extends to be wound around the anchor windlass drum on the hull deck.

[0027] The first roller 1 includes a first roller 1.1, a first roller shaft 1.2, and a first roller bracket 1.3. The first roller shaft 1.2 is inserted into the through hole of the first roller bracket 1.3, and the first roller 1.1 is sleeved on the first roller shaft 1.2 and can rotate freely around the first roller shaft 1.2; the second roller 2 includes a second roller 2.1, a second roller shaft 2.2, and a second roller bracket 2.3. The second roller shaft 2.2 is inserted into the through hole of the second roller bracket 2.3, and the second roller 2.1 is sleeved on the second roller shaft 2.2 and can rotate freely around the second roller shaft 2.2; the third roller 3 includes a third roller 3.1 and a third roller shaft 3.2. The third roller shaft 3.2 is inserted into the through hole of the second roller bracket 2.3, and the third roller 3.1 is sleeved on the third roller shaft 3.2 and can rotate freely around the third roller shaft 3.2. The first roller bracket 1.3 and the second roller bracket 2.3 are both installed on the vertical plate of the front end of the hull facing the water.

[0028] The scraper 5 is made of polyurethane elastomer and is divided into two left and right pieces. The left and right scrapers 5 are fitted on the traction anchor rope 4 through the extrusion of the clamping mechanism 8; the clamping mechanism 8 includes two left and right guide chambers 8.1 and two spring pieces 8.2. The guide chamber 8.1 is installed on the inner side of the second roller bracket 2.3. The spring pieces 8.2 and the scraper 5 are inserted into the inner cavity of the guide chamber 8.1 in turn. The scraper 5 is pressed against the traction anchor rope 4 under the elastic force of the spring pieces 8.2.

[0029] The brush 6 is divided into two parts, including a first brush 6.1 adjacent to the scraper 5 and a second brush 6.2 adjacent to the second roller 2.1. The brush head of the first brush 6.1 is made of bronze or stainless steel with a hardness of 20HRC-30HRC; the brush head of the second brush 6.2 is made of wear-resistant resin, preferably nylon.

[0030] The left and right brushes 6 are fitted on the traction anchor rope 4 by the squeezing effect of the clamping device 9; the clamping device 9 includes four guide shafts 9.1 and four springs 9.2, the guide shaft 9.1 is connected to the brush 6 and inserted into the through hole of the second roller bracket 2.3, and the guide shaft 9.1 can slide axially in the through hole of the second roller bracket 2.3; the spring 9.2 is sleeved on the outer periphery of the guide shaft 9.1, and the two end surfaces of the spring 9.1 are respectively pressed against the brush 6 and the second roller bracket 2.3; the brush 6 is pressed against the traction anchor rope 4 by the elastic force of the spring 9.1.

[0031] Four air jets 7 located on the water surface are also arranged around the traction anchor rope 4 between the first roller 1 and the second roller 2. The four air jets 7 are arranged uniformly along the circumference in a staggered manner around the traction anchor rope 4, and the air jets 7 are connected to the exhaust pipe of the pneumatic dredging pump.

[0032] During dredging, the anchor drum rotates to tighten the traction anchor rope 4 to drag the hull forward. The traction anchor rope 4 with silt sticking to it passes through the third roller 3.1, the scraper 5, the brush 6.1, and the brush 6.2 in sequence to the second roller 2.1, then turns and extends upward to the first roller 1.1, and then turns and extends horizontally after passing the first roller 1.1 to be wound around the anchor drum on the hull deck.

[0033] The silt stuck on the traction anchor rope 4 first passes through the scraper 5 located under the water surface. The large pieces of silt attached to the outer surface of the traction anchor rope 4 fall off under the blocking of the scraper 5 and the combined action of the water flow. The remaining small amount of silt passes through the metal brush 6.1 and the resin brush 6.2 located underwater in turn. The metal brush 6.1 has high strength and hardness, and can brush away most of the silt attached to the traction anchor rope 4 with the help of the water flow. The resin brush 6.2 has better flexibility and can fit more closely with the traction anchor rope 4, so that the mud particles remaining in the gaps of the wire rope can be thoroughly brushed clean with the help of the water flow.

[0034] When the traction anchor rope 4 that has been cleaned of silt passes through the second roller 2.1 and moves toward the first roller 1.1, the air nozzles 7 arranged in a staggered manner in a ring spray out high-pressure air to dry the moisture attached to the steel wire rope; the air nozzles 7 arranged in a ring allow all sides of the steel wire rope to be blown by wind, and the staggered arrangement avoids the offset of wind forces in different directions, so that the air nozzles 7 can blow the traction anchor rope 4 more thoroughly. The air nozzles 7 are connected to the exhaust pipe of the pneumatic dredging pump, and the high-pressure air sprayed by the air nozzles 7 comes from the exhaust gas discharged by the pneumatic dredging pump. The function of air blowing the traction anchor rope can be realized without providing an additional air source, which effectively saves energy consumption.

[0035] Although the present invention has been described in detail using specific embodiments, it will be apparent to those skilled in the art that various changes can be made without departing from the spirit and scope of the present invention.
