Description

Technical Field

[0002] A ship lift is a "navigation structure" set up for ships to pass through the concentrated water level difference on the channel. It consists of upper and lower locks, a ship-carrying compartment, a supporting guide structure and a driving device, and can be divided into two categories: vertical ship lifts and inclined ship lifts.

[0003] However, the existing vertical and inclined ship lifts do not have two symmetrical ship boxes, and can only lift one ship at a time, resulting in low ship navigation efficiency.

[0048] During specific operation, the bidirectional gravity-balanced energy-saving ship lift in the present application has a variable water level difference between the upstream and downstream sides of the dam in different seasons. Therefore, before the ship lift works, the staff needs to control the synchronous movement of several first tensioning hydraulic cylinders 34 and second tensioning hydraulic cylinders 36 through an external central computer. Through the synchronous movement of several first tensioning hydraulic cylinders 34 and second tensioning hydraulic cylinders 36, the length of the outer steel cable 58 and the inner steel cable 71 in the shaft is adjusted so that the standard water level lines inside the first ship holding box 9 and the second ship holding box 10 are flush with the upstream and downstream liquid levels.When a ship lift needs to lift two ships at the same time, first, the staff controls the external central control computer to open the transition exit gate 68 and the transition entrance gate 66 provided on both sides of the transition ship box 70 in sequence, and then controls the outer first progressive safety clamp 13 and the outer second progressive safety clamp 19 to clamp the outer steel cable 58, the inner first progressive safety clamp 42 and the inner second progressive safety clamp 43 to clamp the inner steel cable 71, and turns off the screw motor to lock the trapezoidal screw 55 located inside the trapezoidal screw installation groove 62. Since the trapezoidal screw 55 and the screw nut 53 are self-locking and the outer steel cable 58 and the inner steel cable 71 are clamped, the first ship holding box 9 and the second ship holding box 10 are fixed. Then, the staff controls the external central control computer in sequence. The first inlet reversible gate 44, the second inlet reversible gate 45, the first outlet reversible gate 46, and the second outlet reversible gate 47 provided inside the first ship holding box 9 and the second ship holding box 10 are opened. After the water flows into the ship holding box and the water surface is stable, the ship is driven to the middle of the main ship box 39, and the water levels of the first ship holding box 9 and the second ship holding box 10 are kept at the same height. Then, the first inlet reversible gate 44, the second inlet reversible gate 45, the first outlet reversible gate 46, and the second outlet reversible gate 47 are closed in sequence. After that, the staff controls the outer first progressive safety clamp 13 and the outer second progressive safety clamp 19 to loosen the outer steel cable 58, and the inner first progressive safety clamp 42 and the inner second progressive safety clamp 43 to loosen the inner steel cable 58 through the external central control computer. The cable 71 is turned on, the screw motor is turned on, and the outlet pipe port 51 provided inside the downstream ship-carrying box is opened. The water volume in the inlet water tank 40 and the outlet water tank 41 provided on both sides of the downstream ship-carrying box decreases. Driven by gravity, the upstream ship-carrying box starts to move downward, and the downstream ship-carrying box starts to move upward. When the speed reaches the specified value, the external central control computer opens the outlet pipe port 51 provided inside the upstream ship-carrying box to release water, and closes the outlet pipe port 51 after the weights of the two ship-carrying boxes are consistent. At this time, the two ship-carrying boxes move at a uniform speed. When the upstream ship-carrying box is about to reach the downstream, the outlet pipe port 51 of the upstream ship-carrying box is opened, and the water volume in the inlet water tank 40 and the outlet water tank 41 provided on both sides of the upstream ship-carrying box decreases. Driven by gravity, the ship-carrying box starts to decelerate. When it reaches At the end point, the speed of the ship-carrying box drops to zero, the external central control computer controls the outer first progressive safety clamp 13 and the outer second progressive safety clamp 19 to clamp the outer steel cable 58, the inner first progressive safety clamp 42 and the inner second progressive safety clamp 43 to clamp the inner steel cable 71, and the screw motor stops rotating, so that the first ship-carrying box 9 and the second ship-carrying box 10 are fixed, and the staff opens the transition exit gate 68 and the transition entrance gate 66 provided on both sides of the transition ship-carrying box 70 in sequence through the external central computer, and then opens the exit first reversible gate 46, the exit second reversible gate 47, the entrance first reversible gate 44, and the entrance second reversible gate 45 provided inside the first ship-carrying box 9 and the second ship-carrying box 10 in sequence. After the water surface is stable, the ship is driven away from the ship-carrying box.During the movement of the ship holding box, the external central computer controls the speed of the screw motor to cooperate with the ship holding box to complete the vertical movement. When the speed sensor 59, the acceleration sensor 60, and the laser radar ranging sensor 61 detect that the movement of the ship holding box is faulty, and the tension sensor 57 detects a large change in the tension of the steel cable, the external central computer turns off the screw motor, and the trapezoidal screw 55 and the screw nut 53 are self-locked, and the outer first progressive safety clamp 13 and the outer second progressive safety clamp 19 are controlled to clamp the outer steel cable 58, and the inner first progressive safety clamp 42 and the inner second progressive safety clamp 43 are controlled to clamp the inner steel cable 71, so that the first ship holding box 9 and the second ship holding box 10 stop moving, which can effectively reduce the occurrence of accidents and improve the safety of the ship lift.

[0049] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Substantially" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" includes any direct and indirect electrical coupling means. Therefore, if the text describes a first device coupled to a second device, it means that the first device can be directly electrically coupled to the second device, or indirectly electrically coupled to the second device through other devices or coupling means. The subsequent description of the specification is a preferred embodiment of the present application, but the description is for the purpose of illustrating the general principles of the present application, and is not used to limit the scope of the present application. The scope of protection of the present application shall be determined by the attached claims.

[0050] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.
