Be provided with the hole 303 of permeating water along first cavity 301 lateral wall, the hole 303 of permeating water communicates first cavity 301 and sea water, and at the ascending in-process of water level, the sea water gets into first cavity 301 through the hole 303 of permeating water, and when the water level descends, the sea water is through the hole 303 of permeating water outflow first cavity 301.

At least two clapboards are arranged in the second cavity 302 along the height direction, each clapboard is connected with the longitudinal clapboard 307 and the cavity side wall 308, the second cavity is divided into a plurality of second sub-cavities, a cavity board is further arranged in each second sub-cavity, the first end of the cavity board is arranged on the cavity side wall 308 on the opposite side of the longitudinal clapboard 307, and a gap is formed between the second end and the corresponding clapboard. Each second sub-cavity is internally provided with a floating block, and the size of the floating block is configured to be capable of sealing a gap between the cavity plate and the corresponding partition plate; a plurality of through holes 315 are formed in the longitudinal partition 307, and through holes are formed in the longitudinal partition 315 close to the partition 307 and are arranged along the height direction of the longitudinal partition 307 to communicate the first cavity 301 with each second sub-cavity; an air hole is arranged along the side wall of the second cavity 302 and connected with an air pipe, and the air hole is arranged on the side wall 308 of the cavity between the partition plate and the cavity plate; each air pipe is connected with an air pressure gauge.

The specific structure of the second chamber 302 and the operation principle of the water level adaptive mechanism will be described below with reference to the case including three partition plates and three chamber plates.

A first partition plate 304, a second partition plate 305, and a third partition plate 306 are provided in this order in the height direction of the water tank 3. The first ends of the three partition plates are all fixedly connected to the longitudinal partition plate 307, the end portions of the other three side edges are all connected to the three cavity side walls 308 of the second cavity 302, and the second cavity 302 is divided into three second sub-cavities from bottom to top along the height direction of the water tank 3. Along the height direction of the water tank 3, a first chamber plate 309, a second chamber plate 310 and a third chamber plate 311 are sequentially arranged, wherein the first chamber plate 309 is located below the first partition plate 304, a gap is formed between the first chamber plate 309 and the second chamber plate 310, the second chamber plate 310 is located below the second partition plate 305, a gap is formed between the first chamber plate and the second chamber plate, and the third chamber plate 311 is located below the third partition plate 306, a gap is formed between the first chamber plate and the third chamber plate.

The floating blocks are made of materials capable of floating on the water surface, and are also three, namely a first floating block 312, a second floating block 313 and a third floating block 314, and the three floating blocks are respectively arranged in 3 sub-cavities from bottom to top. The floating block is cylindrical.

Along with the rising of the water level, seawater enters the first cavity 301 through the water permeable holes 303, then enters the sub-cavity a1201 at the lowest part through the through hole 315 of the longitudinal partition plate 307 at the position of the sub-cavity a1201 and the first cavity 301, the water level in the first cavity 301 and the water level in the sub-cavity a1201 are consistent with the external water level and rise synchronously, and the first floating block 312 rises along with the water level until the opening between the first partition plate 304 and the first cavity plate 309 can be sealed. At this time, the gap between the first partition plate 304 and the first cavity plate 309 is closed. The pressure gauge connected to the sub-chamber a1201 detects the pressure change in the chamber in real time, and when the first floating block 312 seals the opening between the first partition plate 304 and the first chamber plate 309, the connection between the sub-chamber a1201 and the barometer 1 is blocked, and the pressure does not change any more.

Similarly, as the water level rises, the pressure of the sub-cavity b1202 and the sub-cavity c1203 generates the same variation trend, and the pressure variation is detected by the corresponding pressure gauge in real time.

In some embodiments of the invention, each partition plate is arc-shaped, the arc-shaped protruding surface of the partition plate faces one side of the bottom of the cavity, and each cavity plate is arc-shaped, and the arc-shaped protruding surface of the partition plate faces one side of the bottom of the cavity. Specifically, with this structure, a bell-mouth shaped gap is formed at the gap between the first partition plate 304 and the first cavity plate 309.

A controller; each barometer is connected and used for collecting the air pressure of each second sub-cavity; and the platform lifting mechanism is further connected and used for adjusting the platform to lift according to the air pressure value of the second sub-cavity. The controller judges the rise and fall of the water level based on the change trend, controls the lifting mechanism, adjusts the motion of the lifting platform 2 by adjusting the rising and falling modes of the limiting column 5, enables the lifting platform 2 to rise and fall along the water level and moves up and down along the slope surface 101 of the fixed platform 1. The specific control principle is explained below.

In some embodiments of the present invention, in order to reduce the motion interference between the position-limiting post 5 and the positioning hole 102, the end of the position-limiting post 5 inserted into the positioning hole 102 is arc-shaped, which facilitates the insertion and removal from the positioning hole 102.

In some embodiments of the present invention, a radial protrusion 501 is radially disposed along the limiting column 5, and a spring 6 is disposed along a lower end surface of the radial protrusion 501, and the spring 6 is fixedly connected to the lifting platform 2. The process that the limiting column 5 moves upwards and is separated from the positioning hole 102 requires the resistance of the spring 6 of the customer; after walking to the position of the next positioning hole 102, the restoring force of the spring 6 pulls the limiting column 5 into the positioning hole 102.

In some embodiments of the invention, the end wall of the lifting platform 2 facing the shore base side is hinged with a pedal 7;

a bracket 8 is arranged on the lifting platform 2, and a pulley 9 is arranged at the upper end of the bracket 8;

the footplate 7 is connected to the restraining pile 5 via a cable 10, which cable 10 passes around a pulley 9, in particular via the top side of the pulley 9, or via the bottom side of the pulley 9.

The pedal 7 can rotate in a certain angle range relative to the lifting platform 2 and can be matched with different heights of the fixed platform 1; in some embodiments, a step 104 is disposed at one end of the fixed platform 1 close to the shore base, and after the lifting platform 2 is moved in place, the pedals 7 can be rotatably fitted to the steps 104 with different heights, so that people or goods can conveniently get on or off the wharf.

The connection structure between the pedal 7 and the limiting column 5 can ensure that the pedal 7, the limiting column 5 and the lifting platform 2 move synchronously. When the lifting platform 2 moves upwards, the wharf is changed from a stable state to a moving state, personnel cannot go up and down the wharf at the moment, the limiting column 5 moves upwards to pull the cable 10, and the pedal 7 rotates upwards relative to the lifting platform 2 and cannot interfere with the fixed platform (particularly the step 104). Similarly, when spacing post 5 downstream, the whole motion state that becomes of pier becomes stable state, and the personnel need use footboard 7 from the pier about, and spacing post 5 descends, drives footboard 7 and slowly falls, takes on step 104.

In some embodiments of the present invention, the fixed platform 1 and the lifting platform 2 are movably coupled with each other as follows. A track 103 is arranged along the length direction of the slope surface 101 of the fixed platform, and a traveling wheel mechanism is arranged along the bottom of the slope surface 201 of the lifting platform and is positioned in the track 103; so that the lifting platform 2 can walk along the fixed platform 3. In order to make the walking more stable, two tracks 103 and two sets of walking wheel mechanisms can be designed.

In some embodiments of the present invention, referring to fig. 4 to 6, the walking wheel mechanism includes a fixing plate 202 disposed along the length direction of the inclined plane of the lifting platform, a wheel axle is disposed along one end of the fixing plate 202 close to the fixing platform 1, walking wheels 203 are disposed at two ends of the wheel axle, and two walking wheels 203 are disposed at two sides of the fixing plate 202;

the rail 103 has a vertical portion 1031 in the depth direction thereof from the side close to the fixed platform ramp surface 101, and straight portions 1032 extending in the width direction to both sides along the vertical portion, i.e., in an inverted "T" shape, and two traveling wheels 203 are located in both straight portions.

By adopting the structure, the movement direction of the lifting platform 2 can be limited by the vertical part of the track, so that the whole lifting platform 2 can only slide relative to the inclined plane 101 of the fixed platform and does lifting movement relative to the sea level; the walking wheels 203 are clamped in the space of the straight part 1032, so that the friction force between the lifting platform 2 and the fixed platform slope surface 101 can be reduced, and the platform can slide more smoothly.

Furthermore, a dolphin 204 is provided at the upper end of the lifting platform 2, which may be used to secure a vessel.

Referring to fig. 9a to 9d, the working principle of the lifting wharf according to the present invention is as follows. In order to distinguish the structure of the component, the subcavities of the second cavity are defined as a subcavity a1201, a subcavity b1202 and a subcavity c1203 one by one from bottom to top.

The data trend of each barometer during the digital change is shown in table 1.

TABLE 1 characteristics of readings of barometers 1, 2, 3 at different water levels

The water level is from low to high	Barometer 1	Barometer 2	Barometer 3
				Water level 1 (Low water level)	Dynamic change of readings	Dynamic change of readings	Dynamic change of readings
Water level 2 (middle and low water level)	The reading is basically stable	Dynamic state of readingsVariations in	Dynamic change of readings
				Water level 3 (middle and high level)	The reading is basically stable	The reading is basically stable	Dynamic change of readings
Water level 4 (high water level)	The reading is basically stable	The reading is basically stable	The reading is basically stable

The wave-breaking cavity and the cavities a, b and c can be regarded as air chambers, and air pressure changes in the cavities can be caused when waves enter the wave-breaking cavity and the cavities a, b and c. However, because the heights of the cavities a, b and c are different, the air pressure in the three cavities is different under different water levels.

As shown in fig. 9a, when the water level is lowest, the water level does not exceed the bell mouth above the cavity a. At this time, the cylinder 1 floats on the water surface in the cavity a, and the cylinder 2 and the cylinder 3 are both at the lowermost ends of the respective cavities. At this time, the wave-dissipating cavity is communicated with the cavities a, b and c, and the air flows in the cavities a, b and c can respectively enter the air delivery pipes 1, 2 and 3. Therefore, the air pressure change in the wave-dissipating cavity causes the barometers 1, 2 and 3 to dynamically change.

As shown in fig. 9b, when the water level rises to the water level 2, seawater submerges the bell mouth above the sub-cavity a1201, the first floating block 312 is located at the top end of the sub-cavity a1201, and blocks the bell mouth above the sub-cavity a1201, and air flow cannot enter the air delivery pipe 1 through the sub-cavity a 1201. Gas flow may enter subcavities b1202 and c1203 from first chamber 301 through vias 315, resulting in dynamic changes in the readings of barometers 2 and 3, while the reading of barometer 1 is stable.

As shown in fig. 9c, when the water level rises to water level 3, seawater submerges the bell mouths above the sub-cavities a1201 and b1202, and the cylinder 1 is located at the top end of the sub-cavity a1201 and blocks the bell mouth above the sub-cavity a 1201. The cylinder 2 is located at the top of the sub-cavity b1202, blocking the flare above the sub-cavity b 1202. The airflow cannot enter the air delivery conduits 1 and 2 through the sub-cavities a1201 and b 1202. Air flow may pass from the wave-dissipating chamber through the through-hole 315 into the subcavity c1203, resulting in dynamic changes in the readings of barometer 3, while the readings of barometers 1 and 2 are stable.

As shown in fig. 9d, when the water level rises to water level 4, the seawater submerges the bell mouth above the sub-cavities a1201, b1202 and c1203, and the cylinder 1 is located at the top end of the sub-cavity a1201, blocking the bell mouth above the sub-cavity a 1201. The cylinder 2 is located at the top of the sub-cavity b1202, blocking the flare above the sub-cavity b 1202. The cylinder 3 is located at the top of the subcavity c1203, blocking the bell mouth above the subcavity c 1203. The air flow cannot enter the air delivery conduits 1, 2, and 3 through the subcavities a1201, b1202, and c 1203. The readings of barometer 1, barometer 2 and barometer 3 are stable.

In the water level dropping process, the change of the readings of the barometer 1, the barometer 2 and the barometer 3 can refer to the change from the water level 4 to the water level 1, and the description is omitted.

When the controller receives the readings of the 3 barometers, the controller makes a judgment to determine the current water level condition. If the water level rises or falls, the controller sends an instruction to the lifting control mechanism to adjust the movement of the limiting pile 5 and control the lifting platform 2 to rise or fall so as to adapt to the change of the water level. And in the process of changing the water level from 1 to 4, the lifting platform 2 is controlled to ascend, and in the process of changing the water level from 4 to 1, the lifting platform 2 is controlled to descend. In the process of ascending or descending, the limiting piles 5 need to be pulled out of the positioning holes 102, the lifting platform 2 runs along the rails 103, and then the limiting piles 5 are controlled to be inserted into the positioning holes 102 with proper heights.

For example, the first three barometer readings are all dynamically changed, which indicates that the water level is low; when the reading of the barometer 1 is substantially stable and the readings of the barometers 2 and 3 are dynamically changed, this state represents that the water level has risen, which is a medium or low water level. The controller 11 receives the change, and controls the limiting column 5 to be pulled out from the positioning hole 102, so that the lifting platform 2 can be lifted for a certain distance.

If the water level change range of the area where the lifting wharf is located is large, the number of the second sub-cavity, the number of the matched gas transmission pipes and the number of the barometers can be increased according to actual needs; if the water level variation range of the area where the lifting wharf is located is small, the number of the second sub-cavities, the matched air conveying pipes and the air pressure meters can be reduced. The principle is the same and is not described in detail.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
