Description

Technical Field

[0001] This invention relates to emergency evacuation technology for ships passing through locks, specifically to an emergency safety evacuation system and method for ships passing through locks. Background Technology

[0002] Ship locks are navigation devices in inland waterway transport that connect waterways with different water levels. While vessels are inside the lock chamber, they are in a relatively enclosed water environment with limited space and a single evacuation route. During this time, in the event of emergencies such as lock chamber fires, ship collisions, equipment failures, or abnormal water levels, the rapid and safe evacuation of personnel is directly related to the safety of life and property. Therefore, reliable emergency evacuation equipment is one of the core facilities for ensuring safe navigation through ship locks. However, locks present challenges such as long rescue times, poor safety, and significant environmental limitations. Currently, traditional emergency rescue methods largely rely on conventional equipment such as cranes and rope ladders. However, these traditional rescue methods suffer from problems such as long rescue times, poor safety, and significant environmental limitations, specifically: 1. Long rescue preparation time: Crane equipment takes a long time to position, and rope ladders require time-consuming manual handling; 2. Poor safety: Rope ladders are structurally unstable and prone to tipping over or breaking, and the stability of crane lifting equipment is affected by factors such as wind and water flow, posing a risk of personnel falling; 3. Significant environmental limitations: Severe weather conditions can severely impact rescue efforts.

[0003] Therefore, it is necessary to improve existing technologies. Summary of the Invention

[0046] In this invention, the car lifting motor unit 2015, the tilting motor unit 2021, and the seat lifting motor unit 3021 are all existing mature equipment.

[0047] Example 1 like Figure 1 The diagram illustrates an emergency safety evacuation system for ships passing through a lock, comprising a lock assembly, a car assembly 2, a lifting assembly 3, a measuring assembly, and an electrical control assembly. The components are described below.

The lock 1 has a vertical shaft 101 for the passage of the car 203, with four guide rails 103 symmetrically arranged vertically on both sides of the shaft 101. The support platform 102 is used in conjunction with the shaft 101 and is installed directly above it to support the entire car assembly 2; the support platform 102 is equipped with various lifting motor units and pulley assemblies, etc.

[0050] 2. Car assembly 2.

[0051] In this embodiment, as Figure 4As shown, the car assembly 2 includes a car lifting mechanism 201, a car guide shoe 2031, a car 203, a safety clamp 2032, a tilting platform 204, wheels 2041, a tilting mechanism 202, a hinge, an angle sensor, a spring assembly 2023, a rotating mechanical limiter, and a bottom float 205.

[0052] (1) The car lifting mechanism 201 includes a car lifting motor unit 2015, a car lifting drum 2011, a car lifting wire rope 2014, a car lifting fixed pulley assembly 2012 installed on the top of the support platform 102, and a car lifting movable pulley assembly 2013 installed on the top of the car 203; The car lifting motor unit 2015 has two sets, symmetrically arranged at both ends of the car lifting drum 2011, forming a dual-sided synchronous drive and braking constraint for the car lifting drum 2011. The car lifting motor unit 2015 includes a motor 20151 (with brake), a coupling 20154, a reducer 20152, a hydraulic drum brake 20153, and a brake wheel coupling 20155 connected in sequence. The end of the brake wheel coupling 20155 is connected to the shaft of the car lifting drum 2011. Two sets of supports are symmetrically arranged on both sides of the car lifting drum 2011, serving as mounting bases for the drive and braking components such as the motor 20151, reducer 20152, and hydraulic drum brake 20153. The bearing seats provide radial and axial positioning for the rotating components such as the shaft of the car lifting drum 2011 and the brake wheel coupling 20155. The car lifting drum 2011 is wound with a car lifting wire rope 2014. The car lifting wire rope 2014 of the car lifting mechanism 201 passes through the car lifting fixed pulley assembly 2012 and the car lifting movable pulley assembly 2013 before connecting to the top of the car 203. The forward and reverse rotation of the car lifting drum 2011 causes the car lifting wire rope 2014 to contract or unwind, thereby driving the car 203 to rise and fall. The car lifting motor unit 2015 is existing mature equipment and will not be described in detail here.

[0053] (2) There are 8 car guide shoes 2031, which are installed on four guide rails 103 and can slide up and down along the guide rails 103.

[0054] (3) The car 203 is used to carry people; the car 203 is equipped with a tilting platform 204; the side of the car 203 is connected to the car guide shoe 2031.

[0055] (4) The safety clamp 2032 is connected to the guide rail 103 to clamp the rail in an emergency to prevent the car 203 from falling. It is a commonly used safety device.

[0056] (5) The lower part of the tilting platform 204 is installed on the opening side of the car 203 by two hinges; the upper end of the tilting platform 204 is a free end, which can be tilted around the hinges; the free end of the tilting platform 204 is equipped with two sets of wheels 2041; when the tilting platform 204 is attached to the ship, it contacts the ship deck through the wheels 2041. When the ship rolls, the wheels 2041 roll on the ship deck.

[0057] (6) There are two sets of wheels 2041, which are installed on the outside of the free end of the overturning platform 204. After being overturned and connected with the ship, the wheels 2041 are located on the lower surface of the overturning platform 204.

[0058] (7) The flipping mechanism 202 includes a flipping motor assembly 2021, a flipping drum 2024, and a flipping wire rope 2022. There are two sets of flipping drums 2024, symmetrically arranged on both sides of the drive end of the flipping motor assembly 2021, driving the flipping drums 2024 to rotate. One end of the flipping wire rope 2022 is wound around the flipping drum 2024, and the other end of the flipping wire rope 2022 passes around the flipping pulley assembly 2025 and is connected to the upper end face of the flipping platform 204. The flipping motor assembly 2021 includes a three-in-one geared motor and a coupling. The two ends of the three-in-one geared motor are respectively connected to the shaft of the flipping drum 2024 through the coupling. The flipping motor assembly 2021 and the flipping drum 2024 are provided with an installation foundation through bearing seats and supports. The flipping motor assembly 2021 is an existing mature device and will not be described in detail here.

[0059] (8) An angle sensor is installed on one of the hinges to detect the tilting angle of the tilting platform 204 relative to the car 203.

[0060] (9) There are two sets of spring assemblies 2023, which are installed on both sides of the car 203.

[0061] (10) A rotating mechanical limiter is installed at the connection between the car 203 and the tilting platform 204 to prevent the tilting platform 204 from tilting too much.

[0062] (11) The bottom float 205 is installed at the bottom of the car 203. The bottom float 205 is conical in shape. When the car 203 falls into the water due to a sudden malfunction, the bottom float 205 can greatly reduce the instantaneous impact between the bottom float 205 and the water surface by means of the guiding effect of the conical surface, so as to ensure the safety of personnel. In addition, it can provide buoyancy for the car 203 in an emergency, so that the car 203 can float on the water surface.

[0063] 3. Lifting component 3.

[0064] In this embodiment, the lifting assembly 3 includes a seat lifting mechanism 302, a lifting seat 301, and a seat guide shoe 3012, as follows: Figure 5 As shown.

The seat lifting motor assembly 3021 includes a three-in-one geared motor and a coupling, which is connected to the tilting drum 2024 (the tilting drum 2024 is supported by bearing seats at both ends). The tilting wire rope 2022 is wound on the tilting drum 2024, and the other end of the tilting wire rope 2022 passes around the seat lifting pulley assembly and is connected to the lifting seat 301. The three-in-one geared motor drives the tilting drum 2024, and the tilting drum 2024 rotates forward and backward to wind up and unwind the tilting wire rope 2022. When the tilting wire rope 2022 is relaxed and extended, the lifting seat 301 floats up under the buoyancy of the water. Figure 8 As shown; The seat lifting pulley assembly includes three seat lifting fixed pulley assemblies 3024, which are respectively located at the top of the support platform 102, the lower part of the side wall of the shaft 101, and the bottom of the shaft 101; the seat lifting wire rope 3023 passes around the fixed pulleys on the support platform 102 in sequence, extends to the lower part of the shaft 101, passes around the two fixed pulleys on the side and bottom of the shaft 101, and finally connects to the bottom of the lifting seat 301.

[0066] (2) A conical groove 3011 is provided on the top of the lifting seat 301, which matches the conical shape of the bottom float 205; a seat guide shoe 3012 is installed on the side of the lifting seat 301, so that the lifting seat 301 can move up and down along the four guide rails 103; under normal circumstances, the seat lifting wire rope 3023 is in a taut state, so that the lifting seat 301 is underwater.

[0067] (3) There are 8 float guide shoes, which are arranged on four guide rails 103 respectively, and can drive the lifting seat 301 to slide up and down along the guide rails 103.

[0068] 4. Measurement components.

[0069] In this embodiment, the measuring components include an optical scanner, a rangefinder, and a lock level gauge, all of which are connected to the electrical control box 4.

[0070] Example 2 In the event of an emergency, personnel on ships within lock 1 must evacuate immediately. One emergency safety evacuation method is as follows: S1. Collect ship berthing information and set the initial descent height of car 203: The lock water level gauge measures the current water level data inside the lock 1 and transmits it to the electrical control box 4. The electrical control box 4, combined with the preset initial height parameters of the car 203, calculates the current vertical distance between the car 203 and the water surface. The rangefinder synchronously collects the vertical distance data between the car 203 and the water surface and sends it to the electrical control box 4; The electrical control box 4 compares and verifies the two sets of vertical distance data. If the data deviation meets the preset accuracy requirements, the distance measuring instrument is deemed to be accurate. The electrical control box 4 sets the initial descent height of the car 203 based on this accurate data and proceeds to the next step. If the deviation between the two sets of data exceeds the set range, it indicates that there is an abnormality in the measuring component. The system is switched to manual observation mode, and the operator sets the initial descent height of the car 203. S2, Lowering the car 203: The electrical control box 4 controls the start of the car lifting mechanism 201, drives the car lifting drum 2011 to release the car lifting wire rope 2014, and drives the car 203 to descend vertically along the guide rail 103, so that the car 203 descends to the initial descent height value set in S1. At this time, the vertical distance between the opening of the car 203 and the ship deck is 50~100mm, and the car lifting mechanism 201 stops. S3. Activate the optical scanner to perform a second precise measurement of the relative position of the car 203 and the ship's deck, and complete the overlapping preparation and unfolding of the tilting platform based on the measurement results: The optical scanner simultaneously collects the vertical and lateral distances between the car 203 and the ship deck, and feeds the data back to the electrical control box 4 in real time. The electrical control box 4 prioritizes the lateral distance data to determine the feasibility of the overlap: if the lateral distance exceeds the maximum effective overlap range of the tilting platform 204 (i.e., it cannot contact the ship deck after tilting), it is determined that the current working condition does not meet the rescue conditions, and an alarm signal is automatically issued and the subsequent process is terminated; if the lateral distance is within the effective overlap range, the electrical control box 4 controls the car lifting mechanism 201 to make fine adjustments to the car 203 based on the vertical distance data, so that the opening height of the car 203 forms the best overlap angle (which can be flush) with the ship deck; then it controls the tilting mechanism 202 to start, driving the tilting drum 2024 to release the tilting wire rope 2022; under the combined action of the elastic thrust of the spring assembly 2023 and its own weight, the tilting platform 204 tilts downward around the hinge end with the car 203 until the free end overlaps with the ship deck, forming a personnel evacuation transition channel, and the tilting mechanism 202 stops and locks. S4. Personnel enter car 203: Personnel in distress on the ship enter the car 203 one by one via the tilting platform 204; S5. Tilting platform 204 reset: After all personnel are in place, the tilting mechanism 202 runs in reverse, the tilting drum 2024 tightens the tilting wire rope 2022, and drives the tilting platform 204 to rotate around the hinge end toward the car 203 until it is reset to the opening of the car 203. S6, Car 203 Lifting: The car lifting mechanism 201 is restarted, the car lifting drum 2011 tightens the car lifting wire rope 2014, driving the car 203 to rise vertically along the guide rail 103, transferring personnel to the support platform 102 at the top of the hoistway 101; personnel evacuate from the support platform 102 to a safe area through the emergency exit of the lock 1, completing the emergency evacuation.

[0071] In this invention, if the ship rolls during the transfer of personnel via the tilting platform 204, the tilting platform 204 can adaptively rotate synchronously with the ship's deck angle. An angle sensor monitors the rotation angle of the tilting platform 204 in real time. When the ship's roll angle is too large, causing the rotation angle of the tilting platform 204 to reach a preset threshold, the electrical control box 4 immediately triggers the tilting mechanism 202 to operate, tightens the tilting wire rope 2022, and the tilting platform 204 stops tilting. If the angle sensor malfunctions or the tilting mechanism 202 fails, causing the rotation angle of the tilting platform 204 to exceed the safe range, the preset rotation mechanical limit component forcibly restricts the extreme rotation position of the tilting platform 204.

[0072] In this invention, if the car lifting mechanism 201 malfunctions during the ascent of the car 203, the system activates triple braking protection: the brakes of the motor 20151 of the car lifting mechanism 201, the hydraulic drum brake 20153, and the safety clamp 2032 are triggered simultaneously to quickly lock the car 203, effectively preventing the car 203 from rushing upwards or falling.

[0073] In this invention, if the car lifting mechanism 201 malfunctions, causing the triple braking protection to fail, or if the car lifting wire rope 2014 breaks, causing the car 203 to fall, the bottom float 205 (conical vertical arrangement) enters the water first with its smaller diameter end to reduce the instantaneous impact upon entering the water. After the car 203 stops falling, the bottom float 205 lifts the car 203 under the action of buoyancy, causing the main body of the car 203 to float above the water surface. If the car 203 cannot rise normally after entering the water, the seat lifting mechanism 302 can be activated to release the seat lifting wire rope 3023, causing the seat 301 to float upward with buoyancy. After the conical groove 3011 of the seat 301 aligns with the bottom float 205, the seat 301 can push the entire car 203 out of the water, realizing a secondary rescue of the car 203 and personnel.

[0074] In this invention, if the car 203 cannot rise normally after entering the water, the seat lifting mechanism 302 controls the seat lifting wire rope 3023 to loosen, and the lifting seat 301 begins to float. After the conical groove 3011 in the lifting seat 301 connects with the bottom float 205, the lifting seat 301 pushes the car 203 out of the water.

[0075] In this invention, the emergency safety evacuation system supports both electric and manual operation, is compatible with various locks on inland waterways and coastlines, and its modular design facilitates installation and maintenance.
