Description

Technical Field

[0001] The invention belongs to the technical field of damping and shock absorption, in particular to the technical field of shock absorption of large ship lock structures, and relates to a large ship lock sway reduction device with electromagnetic energy consumption. Background Art

[0002] A ship lock is a hydraulic engineering facility consisting of a gate and a water pump. It is a major ship-passing structure that connects different water systems and overcomes concentrated water level differences. When a ship wants to pass through a waterway, a water pump pumps water out or injects it into the ship lock, thereby adjusting the water level so that the ship can pass smoothly. This facility is built at the intersection of rivers and canals, river sections with large water level differences, and waterfalls or rapids in rivers. When the ship lock structure is damaged, it may cause water to run away uncontrolled, causing floods, inundation and other disasters in the surrounding areas. Therefore, the safety of the ship lock structure is crucial to the development of river traffic and the convenience of transportation.

[0003] As a large structure, the ship lock needs to bear the external water pressure of the river. When the water level inside and outside the ship lock is adjusted, the water flowing in the ship lock will not only generate dynamic water pressure on the gate and the ship lock structure, but also cause the ship to collide with the ship lock structure during the passage. In order to reduce the impact of the water body on the ship lock structure and reduce the risk of collision between the ship and the ship lock, a shock absorbing device installed on the ship lock structure is proposed. The device can reduce the dynamic water pressure of the water body on the ship lock structure, and at the same time consume the energy in the water body through the energy dissipation principle, reduce the fluctuation amplitude of the water body, reduce the possibility of collision between the ship and the ship lock, and ensure the safety of the ship lock structure. Summary of the invention

[0004] The present invention provides a sway reduction device which can effectively reduce the impact of water flow on a ship lock structure. The device is installed on the ship lock structure and can consume energy in the water body through the energy dissipation principle during water level adjustment, thereby reducing the sway amplitude of the water body and improving the safety of the ship lock structure during operation.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

The six horizontal gas springs are separated from the lower circular surface 12 by a certain distance, and the outer ends of the seven gas springs 3 can be freely extended and retracted.

[0010] The sliding pistons 4 are hollow cylinders with the same structure and size, and there are seven of them, which are installed at the outer ends of the seven gas springs 3; the sliding pistons 4 fixedly installed on the outer end faces of the six horizontal gas springs are called horizontal sliding pistons; one end of the seventh sliding piston 4 is fixedly installed on the outer end face of the vertical gas spring, and the other end is fixedly connected to the inner side face of the upper circular face 11 of the sealing shell 1, which is called vertical sliding piston; the specific structure of the sliding piston 4 is: the left and right end faces of the hollow cylinder (the right end connected to the outer end of the gas spring 3) are both equipped with a first annular magnetic Iron 41, a second annular magnet 42 is installed on the side, and the magnetic poles of the second annular magnet 42 are radially magnetized, that is, the magnetic poles N and S are divided into two semicircular cylinders; a ball screw 43 is arranged horizontally inside the sliding piston 4, and the two ends of the wire lever of the ball screw 43 are respectively fixed vertically to the left and right end surfaces of the sliding piston 4, and the sleeve of the ball screw 43 can move on the wire lever, and a composite metal fan blade 47 is installed on the sleeve, and a third annular magnet 45 is installed at both ends of the sleeve, and the first annular magnet 41 is opposite to the S pole of the third annular magnet 45, so that repulsion is generated when they are close.

The sleeve of the ball screw 43 is fixed to the shaft ring of the second roller 44, and the third annular magnet 45 is fixed to the seat ring of the second roller 44.

Similarly, the outer side surface of the eccentric gear 54 is surrounded by a rectangular surface and a curved surface, and the outer periphery of the curved surface is a gear structure. The rectangular surface of the eccentric gear 54 is fixed to the middle part of the inner side surface of the straight rod 51, and the inner side surface is opposite to the outer side surface on which the arched cylindrical magnet 53 is installed. Specifically: the difference is that the curvature of its side curved surface depends on the gear matching between the eccentric gear 54 and the gear 71, and it is fixed on the other side of the straight rod 51 relative to the arched cylindrical magnet 53, located on both sides of the center of the straight rod, and its thickness is also the same as the width of the straight rod 51, that is, the arched cylindrical magnet 53 and the eccentric gear 54 are respectively located on both sides of the straight rod 51, and the centers of the two coincide with the centers of the upper and lower surfaces of the straight rod 51 respectively. The width of the straight rod 51 is the same as the thickness of the arched cylindrical magnet 53 and the eccentric gear 54, and is in the same horizontal plane. Specifically: one end of the moving rod 5 is hinged to the highest point of the column side of the vertical sliding piston through a circular ring buckle 52, and the angle between the six upper hinge points is 60 degrees. The other end is hinged to the outermost parts of the upper surfaces of the six horizontal sliding pistons through the circular ring buckle 52, that is, the moving rod 5, the six horizontal sliding pistons and one vertical sliding piston constitute six planar isosceles right-angled tripods, which are fixed at the right angles and hinged at the acute angles, and are evenly arranged along the circumference of the vertical sliding piston with an angle of 60 degrees. The fixed rod 6 comprises six groups of straight rods 61 of the same structure, a rotating bracket 62, two rollers 63 and a fan ring magnet 64; the straight rod 61 is a strip rod with a rectangular cross section, and a rotating bracket 62 is fixedly installed at one end. The rotating bracket 62 is a "U"-shaped structure, and circular holes with the same diameter are opened at the same position on both sides. The inner diameter of the circular hole is equal to the outer diameter of the roller 63. The two rollers 63 are kept parallel to the two sides of the rotating bracket 62 and are fixedly installed in the two circular holes respectively, that is, the seat ring of the roller 63 is fixedly installed on the circular hole, and the shaft ring of the roller 63 is fixedly connected to the middle rotating shaft 73 of the enlarged rotating disk 7; the fan ring magnet 64 adopts axial magnetization and is fixed at the middle position of the straight rod 61, and its height (thickness) is consistent with the width of the straight rod 61. The other ends of the six straight rods 61 are respectively fixed on the six rectangular sides of the fixed block 2, that is, located between the horizontal gas spring and the vertical gas spring, with an inclination angle of 45 degrees.There are six groups of the enlarged rotating disks 7, which are respectively installed in cooperation with six groups of fixed rods 6. Each group of the enlarged rotating disks 7 includes a gear 71, two rotating disks 72 and an intermediate rotating shaft 73. The intermediate rotating shaft 73 is installed between the two rollers 63 of the rotating bracket 62; the gear 71 is fixed at the midpoint of the intermediate rotating shaft 73, and the outer end of the gear 71 is in contact with the eccentric gear 54 to realize gear transmission.

[0012] The piston fixed slide 8 includes six groups of open-hole hollow cylinders 81 with the same structure and two fixing frames 82; the open-hole hollow cylinder 81 is a hollow cylinder with a rectangular hole opened along the column line direction, and a horizontal sliding piston is installed inside it, and its inner diameter is slightly larger than the outer diameter of the sliding piston 4; the moving rod 5 is hinged to the horizontal sliding piston and extends out of the piston fixed slide 8 through the rectangular hole, and the lower side of the open-hole hollow cylinder 81 is fixedly installed on the inner side surface of the lower circular surface 12 of the sealing shell 1 through two fixing frames 82.

[0013] Furthermore, the upper circular surface 11 and the lower circular surface 12 of the sealing housing 1 should be made of a light and high-strength metal material that can withstand water pressure, such as aluminum alloy.

[0014] Furthermore, the side of the sealing housing 1 should be made of a waterproof material with good elasticity, such as rubber, and its maximum length in the vertical direction should be greater than the maximum stretching length of the gas spring.

[0015] Furthermore, in order to prevent the rubber shell from being deformed too much in other directions under hydrostatic pressure and affecting the normal operation of the internal structure, the sealing shell 1 should be provided with annular reinforcement ribs on the rubber to ensure that the sway reduction device does not deform under hydrostatic pressure and does not affect the vertical movement of the sway reduction device. Such as rubber.

[0016] Furthermore, the fixing block 2 is made of a light and high-strength metal material that is easy to be fixedly connected by welding, such as aluminum alloy.

[0017] Furthermore, the fixation between the gas spring 3 and the sliding piston 4 should ensure that the center of the circular bottom surface of the sliding piston 2 coincides with the center of the cross section of the gas spring 3 .

[0018] Furthermore, lubricating oil may be added between the sliding piston 4 and the internal copper block 46 to reduce friction.

[0019] Furthermore, the composite metal blades 47 inside the sliding piston 4 are made of light and high-strength conductive materials, such as aluminum alloy, etc., to generate heat and achieve energy consumption.

[0020] Furthermore, the center of the rectangular surface of the arched columnar magnet 53 is aligned with the center of the upper surface of the straight rod 51, and the width of the rectangular surface, that is, the thickness of the arched columnar magnet 53 should be the same as the width of the straight rod 51. The arched columnar magnet 53 is fixed on one side of the straight rod 51, and the arched columnar magnet 53 is axially magnetized.

[0021] Furthermore, the curvature radius of the curved segment of the arched columnar magnet 53 of the moving rod 5 is the same as the radius of the rotating disk 72 of the enlarged rotating disk 7. The eccentric gear 54 of the moving rod 5 is designed with a corresponding development curve according to mechanical principles, so that the eccentric gear 54 and the gear 71 are always kept in contact when the moving rod 5 performs reciprocating motion and realizes gear transmission.

[0022] Furthermore, the rotating disk 72 of the enlarged rotating disk 7 is made of composite metal, such as aluminum alloy, so that it can generate energy to consume energy when rotating.

[0023] Furthermore, the material selected for the piston fixing slide 8 should have anti-magnetic properties, such as aluminum alloy.

[0024] The use process of the present invention is:

[0025] When the water flow impacts the lock structure, the sway reduction device installed on the lock structure will be impacted by the water body, that is, the upper circular surface 11 of the sealing shell 1 will be subjected to water pressure, and then the vertical gas spring fixed below it will be displaced, thereby driving the vertical sliding piston fixed above the vertical gas spring to slide downward. The motion rod 5 is a rigid rod, the upper end of which is hinged to the highest point of the column side of the vertical sliding piston, and the lower end is hinged to the outermost part of the upper end of the column side of the horizontal sliding piston. The outer end of the horizontal sliding piston can be freely extended and retracted, so when the vertical sliding piston slides downward, the motion rod 5 can cause the horizontal sliding piston to be horizontally displaced.

[0026] The sliding piston 4 is displaced, and the third annular magnet 45 and the copper block 46 placed inside are displaced relative to the sliding piston 4 due to inertia. The first annular magnet 41 fixed on the inner side of the left and right end faces of the sliding piston 4 is opposite to the S pole of the third annular magnet 45 embedded in the copper block 46. When the distance between the two becomes smaller, repulsion is generated, thereby intensifying the relative movement between the sliding piston 4 and the internal copper block 46 and the third annular magnet 45. Since the wire lever of the ball screw 43 is vertically fixed on the left and right end faces of the sliding piston 4, and the sleeve of the ball screw 43 is fixed on the assembly of the third annular magnet 45 and the copper block 46, that is, the relative movement between the sliding piston 4 and the internal copper block 46 and the third annular magnet 45 is transformed into the movement between the wire lever of the ball screw 43 and the sleeve, so that the sleeve rotates, and the composite metal fan blade 47 fixed on the sleeve starts to rotate. A second annular magnet 42 is installed on the side of the sliding piston 4 and radial magnetization is adopted, that is, the magnetic poles N and S are divided into two semi-circular cylinders. The composite metal fan blades 47 rotate in the magnetic field generated by the second annular magnet 42 to generate damping and dissipate energy. At the same time, the copper block 46 itself also generates damping and consumes energy when moving in the magnetic field.

[0027] At the same time, the moving rod 5 performs a cyclic reciprocating motion under the action of the gas spring 3, and through the cooperation between the eccentric gear 54 on the moving rod 5 and the gear 71 of the enlarged rotating disk 7, the gear 71 is driven to rotate in different directions; since the gear 71 is fixedly installed at the midpoint of the intermediate rotating shaft 73, it will drive the rotation of the intermediate rotating shaft 73, and then the rotating disk 72 fixed at both ends of the intermediate rotating shaft 73 will rotate; since the positions of the arched columnar magnet 53 fixed on the moving rod 5 and the fan-shaped annular magnet 54 fixed on the fixed rod 5 are between the rotating disk 72, when the rotating disk 72 rotates, heat energy will be generated and energy will be consumed.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] The sway reduction device provided by the present invention has a good rebound effect. It can be installed on the lock structure to effectively reduce the impact of water flow on the structure. The gear transmission rotation amplification method and composite electromagnetic energy consumption are used inside the device to improve the energy consumption efficiency of the device. The device can not only reduce the hydraulic water pressure of the water body on the lock structure, but also effectively consume the energy in the water body when the lock is adjusting the water level, reduce the sway amplitude of the water body, reduce the risk of collision between the ship and the lock, and improve the safety of the lock structure.

[0030] The anti-sway device provided by the present invention has flexible size and is designed in appearance as a sealing structure with upper and lower bottom surfaces being circular planes and side surfaces being centrally symmetrical curved surfaces. It is installed on the surface of the lock structure to reduce the flatness of the lock structure appearance, increase the movement distance of the water flow, slow down the flow rate of the water flow, and reduce other adverse effects of the anti-sway device on the lock structure.

Figure 1 As shown, the self-resetting high-efficiency energy-consuming ship lock sway reduction device is a sealing device, whose lower bottom surface is fixedly installed on the outer surface of the ship lock structure, and the upper bottom surface and the curved side surface are in contact with the water body. The fixed block, gas spring, sliding piston, moving rod, fixed rod, enlarged rotating disk and piston fixed slide are all arranged in a sealed shell and located below the liquid surface.

[0049] like Figure 2 As shown, the sealing shell 1 includes an upper circular surface 11, a lower circular surface 12 and a central symmetrical curved surface 13 with different radii; the radius of the lower circular surface 12 is greater than the radius of the upper circular surface 11, and the radius of the lower circular surface 12 should be greater than the ultimate stretching length of the gas spring 3, and the side of the sealing shell 1 is a central symmetrical curved surface 13 with circular holes on the upper and lower sides, the diameter of the upper opening circle is equal to the diameter of the upper circular surface 11, and the diameter of the lower opening circle is equal to the diameter of the lower circular surface 12; the upper circular surface 11, the central symmetrical curved surface 13 and the lower circular surface 12 are placed from top to bottom, and the joints are sealed to form a sealing shell 1.

[0050] like Figure 3 As shown, the cross section of the fixing block 2 is a regular hexagonal right prism, the center of its lower bottom surface coincides with the center of the lower circular surface 12 of the sealing shell 1, and is fixed on the inner side of the lower circular surface 12 of the sealing shell 1.

[0051] like Figure 4 As shown, there are seven gas springs 3, of which the same end of six gas springs 3 is vertically fixed at the center of the six rectangular sides of the fixed block 2, and the same end of another gas spring 3 is vertically fixed at the center of the upper bottom surface of the fixed block 2, that is, the same end of the seven gas springs 3 is fixed on the fixed block 2, and the six gas springs 3 are evenly arranged along the circumference around a vertical axis in the same horizontal plane, with an angle of 60 degrees, which is called a horizontal gas spring, and the outer end of the horizontal gas spring can move freely; the position of another gas spring 3 coincides with the vertical axis, which is called a vertical gas spring, and its extended end can move freely up and down. Specifically: the seven gas springs 3 are vertically fixed at the center of the seven faces of the fixed block 2, forming an outwardly divergent whole, and are fixed to the center of the lower circular surface 12 of the sealing shell 1 through the lower bottom surface of the fixed block 2. The six horizontal gas springs are separated from the lower circular surface 12 by a certain distance, and the spacing is set to 1cm. At the same time, the extended ends of the seven gas springs 3 can be freely extended and retracted.

[0052] like Figure 5As shown, the sliding piston 4 is a hollow cylinder with the same structure and size, and there are seven of them in total. The sliding pistons 4 fixedly mounted on the outer end faces of the six horizontal gas springs are called horizontal sliding pistons; one end of the sliding piston 4 is fixedly mounted on the outer end face of the vertical gas spring, and the other end is fixedly connected to the inner side face of the upper circular face 11 of the sealing shell 1, which is called a vertical sliding piston; the specific structure of the sliding piston 4 is as follows: the left and right end faces of the hollow cylinder (the right end connected to the outer end of the gas spring 3) are both equipped with a first annular magnet 41, and a second annular magnet 42 is installed on the side, and the magnetic poles of the second annular magnet 42 are radially magnetized, that is, the magnetic poles N and S are divided into two semicircular cylinders. A ball screw 43 is arranged horizontally inside the sliding piston 4. The two ends of the wire lever of the ball screw 43 are respectively fixed vertically to the left and right end surfaces of the sliding piston 4. The sleeve of the ball screw 43 can move on the wire lever. The composite metal fan blade 47 is installed on the sleeve. The third annular magnet 45 is installed at both ends of the sleeve, and the first annular magnet 41 and the third annular magnet 45 are opposite to each other at the S pole, so that repulsion is generated when they are close. The third annular magnet 45 is wrapped with a copper block 46. The copper block 46 acts as a bracket to keep the sleeve of the ball screw 43 horizontal, increase the quality of the internal structure, and has anti-magnetism. It is not affected by the second annular magnet 42, which is conducive to horizontal movement. At the same time, the copper block 46 itself will also generate damping and consume energy when moving in the magnetic field. The sleeve of the ball screw 43 and the third annular magnet 45 are connected by a second roller 44. The sleeve of the ball screw 43 is fixed to the shaft ring of the second roller 44, and the third annular magnet 45 is fixed to the seat ring of the second roller 44.

The rectangular surface of the eccentric gear 54 is fixed to the middle of the inner side surface of the straight rod 51, and the inner side surface is opposite to the outer side surface on which the arched cylindrical magnet 53 is installed. Specifically, the difference is that the curvature of the side curved surface depends on the direct gear matching of the eccentric gear 54 and the gear 71, and it is fixed relatively to the other side of the straight rod 51 with the arched cylindrical magnet 53, and is located on both sides of the center of the straight rod. Its thickness is also the same as the width of the straight rod 51, that is, the arched cylindrical magnet 53 and the eccentric gear 54 are respectively located on both sides of the straight rod 51, and the centers of the two coincide with the centers of the upper and lower surfaces of the straight rod 51 respectively. The width of the straight rod 51 is the same as the height of the arched cylindrical magnet 53 and the eccentric gear 54, and is in the same horizontal plane. Specifically: one end of the moving rod 5 is hinged to the highest point of the column side of the vertical sliding piston through a circular ring buckle 52, and the angle between the six upper hinge points is 60 degrees. The other end is hinged to the outermost parts of the upper surfaces of the six horizontal sliding pistons through the circular ring buckle 52, that is, the moving rod 5, the six horizontal sliding pistons and one vertical sliding piston constitute six planar isosceles right-angled tripods, which are fixed at the right angles and hinged at the acute angles, and are evenly arranged along the circumference of the vertical sliding piston with an angle of 60 degrees.

The rotating bracket 62 is a "U"-shaped structure, and circular holes with the same diameter are opened at the same position on both sides. The inner diameter of the circular hole is equal to the outer diameter of the roller 63. The two rollers 63 are kept parallel to the two sides of the rotating bracket 62 and are fixedly installed in the two circular holes respectively, that is, the seat ring of the roller 63 is fixedly installed on the circular hole, and the shaft ring of the roller 63 is fixedly connected to the middle rotating shaft 73 of the enlarged rotating disk 7; the fan ring magnet 64 adopts axial magnetization and is fixed at the middle position of the straight rod 61, and its height (thickness) is consistent with the width of the straight rod 61. The other ends of the six straight rods 61 are respectively fixed on the six rectangular sides of the fixed block 2, that is, located between the horizontal gas spring and the vertical gas spring, with an inclination angle of 45 degrees.

[0055] like Figure 8 As shown, there are six groups of magnifying rotating disks 7, which are respectively installed with six groups of fixed rods 6. Each group of magnifying rotating disks 7 includes a gear 71, two rotating disks 72 and an intermediate rotating shaft 73; the intermediate rotating shaft 73 is installed between two rollers 63 of the rotating bracket 62. The gear 71 is fixed at the midpoint of the intermediate rotating shaft 73, and the outer end of the gear 71 contacts the eccentric gear 54 to realize gear transmission. The two rotating disks 72 are respectively fixed at the two ends of the intermediate rotating shaft 73, and the fixed positions of the shaft rings of the two rollers 63 in a group of the intermediate rotating shaft 73 and the fixed rod 6 are located at the two gaps between the gear 71 and the two rotating disks 72, that is, the magnifying rotating disk 7 is fixed in position by the fixed rod 6 without affecting its own rotation, and can realize gear transmission through the matching connection between the eccentric gear 54 and the gear 71, so that the moving rod 5 can drive the rotating disk 72 to rotate in different directions when performing reciprocating motion.

[0056] like Fig. 9 As shown, the piston fixed slide 8 includes six groups of open-hole hollow cylinders 81 with the same structure and two fixing frames 82; the open-hole hollow cylinder 81 is a hollow cylinder with a rectangular hole opened along the column line direction, and a horizontal sliding piston is installed inside it, and its inner diameter is slightly larger than the outer diameter of the sliding piston 4; the moving rod 5 is hinged to the horizontal sliding piston and extends out of the piston fixed slide 8 through the rectangular hole, and the lower side of the open-hole hollow cylinder 81 is fixedly mounted on the inner side surface of the lower circular surface 12 of the sealing shell 1 through two fixing frames 82.

[0057] The usage process of this implementation case is:

[0058] When the water flow impacts the sway reduction device installed on the ship lock structure, the sway reduction device installed on the ship lock structure will be impacted by the water body, that is, the upper circular surface 11 of the sealing shell 1 will be subjected to water pressure, and then the vertical gas spring fixed below it will be displaced, thereby driving the vertical sliding piston fixed above the vertical gas spring to slide downward. The motion rod 5 is a rigid rod, the upper end of which is hinged to the highest point of the column side of the vertical sliding piston, and the lower end is hinged to the outermost part of the upper end of the column side of the horizontal sliding piston. The outer end of the horizontal sliding piston can be freely extended and retracted, so when the vertical sliding piston slides downward, the motion rod 5 can cause the horizontal sliding piston to be horizontally displaced.

[0059] The sliding piston 4 is displaced, and the third annular magnet 45 and the copper block 46 placed inside are displaced relative to the sliding piston 4 due to inertia. The first annular magnet 41 fixed on the inner side of the left and right end faces of the sliding piston 4 is opposite to the S pole of the third annular magnet 45 embedded in the copper block 46. When the distance between the two becomes smaller, repulsion is generated, thereby intensifying the relative movement between the sliding piston 4 and the internal copper block 46 and the third annular magnet 45. Since the wire lever of the ball screw 43 is vertically fixed on the left and right end faces of the sliding piston 4, and the sleeve of the ball screw 43 is fixed on the assembly of the third annular magnet 45 and the copper block 46, that is, the relative movement between the sliding piston 4 and the internal copper block 46 and the third annular magnet 45 is transformed into the movement between the wire lever of the ball screw 43 and the sleeve, so that the sleeve rotates, and the composite metal fan blade 47 fixed on the sleeve starts to rotate. A second annular magnet 42 is installed on the side of the sliding piston 4 and radial magnetization is adopted, that is, the magnetic poles N and S are divided into two semi-circular cylinders. The composite metal fan blades 47 rotate in the magnetic field generated by the second annular magnet 42 to generate damping and dissipate energy. At the same time, the copper block 46 itself also generates damping and consumes energy when moving in the magnetic field.

[0060] At the same time, the moving rod 5 makes a cyclic reciprocating motion, and the cooperation between the eccentric gear 54 on the moving rod 5 and the gear 71 of the enlarged rotating disk 7 will cause the gear 71 to rotate. Since the gear 71 is fixedly installed at the midpoint of the intermediate rotating shaft 73, it will drive the rotation of the intermediate rotating shaft 73, and then the rotating disk 72 fixed at both ends of the intermediate rotating shaft 73 will rotate. Since the positions of the arched columnar magnet 53 fixed on the moving rod 5 and the fan-shaped annular magnet 54 fixed on the fixed rod 5 are between the rotating disk 72, when the rotating disk 72 rotates, heat energy will be generated and energy will be consumed.

[0061] The above-described embodiments merely express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, without departing from the concept of the present invention, they can make several modifications and improvements, which should also fall within the scope of protection of the present invention.
