Description
Technical Field
The invention relates to the technical field of ships, in particular to a high-blade small-hub auger-propelled beach-sea amphibious operation ship.
Background
According to the requirements, the eastern provinces can realize local new energy power generation, such as offshore wind power generation, tidal flat solar power generation and the like. The beach solar power generation does not occupy cultivated land, does not influence wetland ecology, has wide development prospect, and has the unique difficulty of lacking a proper operation platform for development and construction and maintenance management after construction.
Because of small bearing pressure in unit area and low friction coefficient, common wheeled vehicles cannot run and can slip or sink on the ground (hereinafter collectively called wetland) such as beach, marsh and the like; the tracked vehicle can pass through a wetland with no deep accumulated water but can also sink into the deep water wetland; ships can sail in deep water but can be stranded in shallow water.
The amphibious spiral propulsion vehicle is characterized in that one or more pairs of rollers which are symmetrically distributed left and right are arranged below a frame of the amphibious spiral propulsion vehicle, continuous spiral blades are fixed on the periphery of the rollers, the spiral directions of the spiral blades on the left and right pairs of rollers are opposite, lateral component force can be effectively counteracted, and the hollow rollers with oversized size can provide enough buoyancy, so that the vehicle can float above the water surface to navigate freely, and besides the vehicle cannot travel continuously on paved roads, the amphibious spiral propulsion vehicle can travel freely on snowfields, wetlands, sandlands and mountain lands covered with vegetation, and can also pass on harder beaches in some cases.
However, the existing spiral propulsion vehicle mainly relies on an oversized-diameter hollow roller to provide supporting force and buoyancy, in order to meet the supporting requirement of harder road conditions (barren land, mountain land and the like), the height of a spiral blade is usually relatively small, the ratio of the height of the spiral blade to the radius of the roller hub (simply called the hub ratio) is usually 0.2-0.3, and when the spiral propulsion vehicle provided with the spiral roller enters a river and sea port alluvial beach operation, the vehicle is easy to sink. The reason is that the tidal flat is usually a sediment type structure, and is completely immersed by water in the process of rising tide, so that the water saturation is higher; after ebb, sediment has resistance (in Bingham fluid character) far beyond the water body, after being disturbed by a propeller, sediment with high saturation degree becomes quicksand (in dilatant fluid character), at the moment, the resistance is reduced, the reverse thrust to the spiral blade is correspondingly reduced, the sediment in front of the spiral roller and the ship body is not disturbed, the resistance is far greater than that of the quicksand, and the situation is further aggravated by the spiral roller with small She Gubi; in addition, the working ship often needs to stop the ship for construction operation, and disturbance (engine vibration and disturbance of working tools) in the working process can further aggravate the sinking of the working ship, just like the sinking of a quicksand beach when a sea man is caught, the conventional spiral propulsion vehicle is more difficult to get out of the way by combining the characteristic of the sedimentary beach. Therefore, there is a need in the market for a beach amphibious workboat that can effectively get rid of the trouble and travel efficiently in the beach, has mature technology, and is easy to popularize.

Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The high-blade small-hub auger propulsion beach amphibious operation ship provided by the embodiment of the invention is described.
Embodiment 1,
As shown in fig. 1, the high-blade small-hub auger propulsion beach amphibious operation ship comprises a ship body 1, auger propellers 2 and a power system, wherein the power system is arranged on the ship body 1, and one or two pairs of auger propellers 2 with opposite directions are arranged on the left side and the right side below the ship body 1 and are respectively and independently driven by the power system.
As shown in fig. 1 and 2, the auger pusher 2 comprises a helical blade 22 and a roller hub 21, wherein the outer periphery of the roller hub 21 is fixedly provided with a continuous helical blade 22, and the ratio of the height of the helical blade 22 of the auger pusher 2 to the radius of the roller hub 21 is not less than 1.
The ratio of the height of the helical blade 22 to the radius of the roller hub 21 is called as the "hub ratio", the high blade thrust is large, and the small hub resistance is small; preferably She Gubi is greater than 1.2. The high helical blades 22 increase thrust and the small diameter roller hub 21 reduces drag.
The ratio of the height of the helical blade of the existing amphibious helical propulsion vehicle to the radius of the drum hub (for short, the ratio of the hub to the blade) is usually 0.2-0.3, and practical applications of She Gubi being larger than 0.5 are not seen, such as the drum hub radius of 400 mm and the helical blade height of 100 mm (the total external diameter of the helical blade is 1000 mm), the ratio of the hub to the blade is equal to 100/400=0.25, and the amphibious helical propulsion vehicle provided with the helical drum is easy to sink when entering the river and sea opening coastal beach operation.
In this embodiment the auger screw 2 has an outer diameter of 600 mm, wherein the radius of the drum hub 21 is 120 mm, the height of the helical blades 22 is 180 mm, and the hub ratio is 180/120=1.5. The effective thrust of auger pusher 2 is increased by decreasing the diameter of drum hub 21 and increasing the height of helical blades 22, i.e., increasing She Gubi. For the auger propeller 2 itself, the cross-sectional area of the drum hub 21 is a resistance area, and the cross-sectional area of the helical blade 22 is a thrust area, so that after the hub ratio is increased, the resistance of the auger propeller 2 can be reduced, the thrust force can be increased, and the hull trapped in the beach can be effectively released.
The ratio of the mud discharge amount of the roller hub 21 of the auger propeller 2 to the weight of the whole ship is not more than 1, so that the auger propeller 2 is insufficient to support the weight of the whole ship body 1, the ship body 1 can be positioned on the surface layer of the beach with higher water saturation and smaller resistance, the auger propeller 2 can penetrate deeper into the deep beach with lower water saturation and larger reverse thrust, the deep mud density is also larger, the thrust area of the auger propeller 2 is multiplied, and the thrust is increased, so that the resistance and the thrust are effectively reduced in the running process. The "sludge discharge" is similar to the "water discharge" of the ship in water, and after the diameter of the drum hub 21 of the auger propeller 2 is reduced, the drum hub 21 receives reduced buoyancy, and the hull 1 is required to bear a part of the buoyancy. The radius of the roller hub 21 of the auger propeller 2 of the embodiment is 120 mm, and the length is 3000 mm; when a pair of auger propellers 2 is arranged below the hull 1, the sludge discharge amount of the two auger propellers 2 is about 0.5 ton, the full load weight of the whole ship is close to 3 tons, and the ratio of the sludge discharge amount of the roller hubs 21 of the auger propellers 2 to the weight of the whole ship is far less than 1.
The bottom of the ship body 1 is provided with an auger support leg 3, and the auger propeller 2 is connected with the ship body 1 through the auger support leg 3; the auger landing leg 3 is of a vertical split telescopic structure and is provided with a vertical telescopic driver for automatically adjusting the height of the landing leg; the length of the auger support legs 3 is adjusted according to different mud and sand properties of the mud flat, and then the mud eating depth of the auger propeller 2 is adjusted. The cross section of the auger supporting leg 3 is preferably diamond, so that the effect of reducing the resistance of the ship can be achieved, and drag reduction can be achieved when the auger propeller 2 turns forward and backward.
In addition, the auger leg 3 is long, so that the upper edge of the roller hub 21 of the auger pusher 2 is lower than the mud line 7; the "mud line" is similar to the "waterline" of the ship in water, preferably the whole auger propeller 2 comprises spiral blades 22 below the mud line 7, the upper edge of the roller hub 21 is below the mud line 7, that is to say the auger propeller 2 is deeply sunk into the mud beach, the ship body 1 generating resistance is positioned on the shallow surface layer of the beach, the water content of the shallow surface layer of the beach is higher, and the resistance of the ship body 1 on the shallow surface layer of the beach is smaller; and auger propeller 2 is located the deep of beach, and the water content of beach depths is lower, and auger propeller 2 rotation receives great thrust in the deep of beach.
The power system is connected with the auger propeller 2 through a bevel gear transmission mechanism; the bevel gear transmission mechanism comprises a bevel gear transmission case 23, a bevel gear input shaft and a bevel gear output shaft are arranged in the bevel gear transmission case 23, and a conical air guide sleeve is arranged at the outer end of the bevel gear transmission case 23, so that the resistance of a ship is further reduced.
The bevel gear input shaft is a vertical shaft, and one end of the bevel gear input shaft is connected with the power system. The other end of the bevel gear input shaft is provided with a drive bevel gear 231, the drive bevel gear 231 is meshed with a driven bevel gear 232, and the driven bevel gear 232 is arranged on the bevel gear output shaft. The end part of the roller hub 21 of the auger propeller 2 is provided with an auger rotating shaft, the output shaft of the bevel gear is a horizontal shaft, and the output shaft of the bevel gear is connected with the auger rotating shaft.
In the amphibious spiral propulsion vehicle in the prior art, a chain transmission is adopted, a driven wheel is positioned at the shaft end of a screw conveyer in a chain transmission structure, a driving wheel is positioned on a ship body, and a protective cover with larger volume is arranged outside the chain; because the diameter of the roller of the amphibious spiral propulsion vehicle is large, the rotating shaft of the roller is positioned above the ground, so that most of the protective cover is positioned in the air, the air resistance of the amphibious spiral propulsion vehicle moving at a low speed is negligible, and the chain transmission structure is simple and low in price, the amphibious spiral propulsion vehicle is widely applied at present, but because the roller of the amphibious spiral propulsion vehicle cannot be wholly immersed in mud, the thrust provided by the spiral blades arranged on the roller is smaller. The high-blade small-hub auger propulsion beach amphibious operation ship adopts bevel gear transmission, so that the auger propeller 2 provides larger thrust and has the advantage of more resistance reduction; according to the auger propeller 2 disclosed by the invention, the diameter of the roller hub 21 is smaller (She Gubi is larger than 1, the mud discharge amount is smaller than 1), so that the whole roller hub 21 is immersed in mud, if a chain is adopted for transmission, the resistance of a chain protection cover with larger volume is overlarge, a transmission mechanism with a bevel gear structure is adopted, a drive of a power system is connected with a driving shaft of a bevel gear transmission case 23, the diameter of a protection pipe sleeved outside the driving shaft is also far smaller than that of the chain protection cover, and therefore, the resistance can be greatly reduced.
The front end of the hull 1 and/or the rear end of the hull 1 are/is provided with a rotation perturber, namely, the amphibious workboat is only provided with the rotation perturber at the front end of the hull 1, or the amphibious workboat is only provided with the rotation perturber at the rear end of the hull 1, or the amphibious workboat is provided with the rotation perturber at both the front end and the rear end of the hull 1. When the ship body 1 advances, the rotary perturber arranged at the front end of the ship body 1 can change the physical properties of the beach at the front end of the ship body 1, so that semi-solid sediment in front of the ship body 1 can be stirred into quicksand to reduce the ship resistance, the ship body 1 can be driven in an auxiliary manner, and the escaping capability and the propelling efficiency of the amphibious operation ship in the mud beach are further improved; when the ship body 1 retreats, the rotary perturbator arranged at the rear end of the ship body 1 can change the physical properties of the back beach of the ship body 1, not only can stir the semisolid sediment behind the ship body 1 into quicksand to reduce the ship resistance, but also can assist in driving the ship body 1, and further improves the escaping capability and the propelling efficiency of the amphibious operation ship in the mud beach. Preferably, the rotational axis of the rotational perturbator is lower than the mud line 7.
As shown in fig. 2 and 3, the rotary perturbator in this embodiment is a transverse contra-rotating auger 4, and the transverse contra-rotating auger 4 includes a front contra-rotating auger 41 and a rear contra-rotating auger 42, where the front contra-rotating auger 41 and the rear contra-rotating auger 42 are provided with left-right-rotating auger sections, and are reversed.
The prepositive contra-rotating auger 41 is arranged at the front end of the ship body 1; the left part of the front contra-rotating auger 41 is a front left-rotating auger section 411, and the right part of the front contra-rotating auger 41 is a front right-rotating auger section 412; front left-handed auger section 411 is laterally arranged with front right-handed auger section 412 in bilateral symmetry and opposite in handedness.
The rear counter-rotating auger 42 is arranged at the rear end of the ship body 1; the left part of the rear contra-rotating auger 42 is a rear right-rotating auger section 422, and the right part of the rear contra-rotating auger 42 is a rear left-rotating auger section 421; the rear right-handed auger section 422 and the rear left-handed auger section 421 are laterally arranged in bilateral symmetry and are opposite in rotation direction.
When the ship body 1 moves, the front contra-rotating auger 41 and the rear contra-rotating auger 42 which are positioned at the front end and the rear end of the ship body 1 rotate forwards; at this time, the front counter-rotating auger 41 has the component force for outward dredging out the silt and backward driving, and has the function of pushing the silt backward and the function of dredging out the silt at the bow; the rear pair of augers 42 have an inward and a rearward component and have the same effect when traveling in the reverse direction (the stern is the front end in this case).
According to the amphibious operation ship, the transverse contra-rotating screw conveyor 4 is additionally arranged at the bow and/or the stern of the ship body 1, sediment (Bingham fluid property) at the front end in the running direction is stirred to become quicksand (dilatant fluid property), and meanwhile sediment in front of the ship body 1 can be hollowed out left and right, so that ship resistance is reduced, and meanwhile, the ship body 1 is assisted to advance.
The power winch 6 is arranged on the ship body 1, and the tug rope of the power winch 6 is tied on the trunk or the pipe pile, so that the amphibious workboat can be assisted to get rid of the trouble under extreme conditions.
Embodiment II,
Compared with the first embodiment, the high-blade small-hub auger propulsion beach amphibious operation ship is characterized in that: as shown in fig. 4, the rotation perturber is a transverse-axis paddle wheel 5, and the transverse-axis paddle wheel 5 includes a front transverse-axis paddle wheel 51 and a rear transverse-axis paddle wheel 52; the front transverse paddle wheel 51 and the rear transverse paddle wheel 52 are provided at the front end and the rear end of the hull 1, respectively. The transverse-axis paddle wheel 5 arranged on the amphibious workboat in the embodiment can change the silt characteristic, disturb the silt (bingham fluid property) at the front end of the running direction of the boat body 1, enable the silt to become quicksand (dilatant fluid property), further reduce the resistance of the boat, and meanwhile the transverse-axis paddle wheel 5 pushes the silt backwards to assist the boat body 1 to advance.
The invention provides a working platform for transporting personnel, materials and equipment, which is suitable for traveling on tidal flat. The ratio of the height of the spiral blade 22 of the auger propeller 2 to the radius of the roller hub 21 is more than 1, the high spiral blade 22 can increase the thrust, and the small-diameter roller hub 21 can reduce the resistance; the beach amphibious operation ship can effectively escape from the ship body sunk into the beach by reducing the diameter of the roller hub 21 and increasing the height of the helical blades 22, namely, increasing She Gubi to reduce the resistance born by the auger propeller 2 and increase the effective thrust of the auger propeller 2. The ratio of the mud discharging amount of the roller hub 21 of the auger propeller 2 to the weight of the whole ship is not more than 1, so that the ship body 1 is positioned on the surface layer of the beach with higher water saturation and smaller resistance, the auger propeller 2 can penetrate deeper into the deep beach with lower water saturation and larger reverse thrust, the thrust area of the auger propeller 2 is multiplied, and therefore the resistance and the thrust are effectively reduced in the process of running the ship, and the problem of escaping is effectively solved. The auger support legs 3 are longer, so that the auger propeller 2 is deeply sunk into the mud beach, the ship body 1 generating resistance is positioned on the shallow surface layer of the mud beach, the water content of the shallow surface layer of the mud beach is higher, and the resistance of the ship body 1 on the shallow surface layer of the mud beach is smaller; and auger propeller 2 is located the deep of beach, and the water content of beach depths is lower, and auger propeller 2 rotation receives great thrust in the deep of beach. The rotary perturber is additionally arranged at the bow and/or stern of the ship body 1 of the beach amphibious operation ship, so that semi-solid sediment in front of the ship body 1 can be stirred into quicksand to reduce resistance, the ship body 1 can be driven in an auxiliary manner, and the escaping capability and the propelling efficiency of the beach amphibious operation ship in mud and sand beach are further improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
