Detailed Description

For the purpose of promoting an understanding of the principles of the invention, reference will now be made in detail to the embodiments of the invention illustrated in the drawings, which are to provide a preferred embodiment of the invention, it being understood that the invention may be practiced in other various embodiments and that the embodiments illustrated in the drawings may be practiced otherwise than as specifically described herein.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

Unless defined otherwise, all techniques and terms used herein are consistent with the meaning understood by those of skill in the art to which the present invention pertains, and the terms used herein are intended for the purpose of describing the examples, and are not intended to limit the embodiments thereof.

The conventional dock socket generally consists of a track foundation and a rigid track which are poured on the water bottom by concrete, and the inventor finds that the concrete pouring is carried out when waiting for a low water level, so that the construction cost is high.

In order to overcome the problems in the prior art, as shown in fig. 1, the present invention provides a lifting socket 100 for wharfs, which includes a lifting rail 10, a socket box 20 and a lifting device 30, wherein the lifting device 30 acts on the socket box 20 and can drive the socket box 20 to move up and down along the lifting rail 10.

The lifting rail 10 comprises a flexible cable and a weight 13 suspended from the end of the cable to keep the cable vertical.

The flexible cable comprises a first cable 11 and a second cable 12 which are arranged side by side, one end of the first cable 11 and one end of the second cable 12 can be fixed on the wharf platform, and the other end is fixed with the heavy hammer 13. The weight 13 can tighten the first cable 11 and the second cable 12 by its own weight to form a sliding track, and both sides of the socket box 20 are slidably connected to the first cable 11 and the second cable 12, respectively.

In one embodiment, a metal ring (not shown) may be fixed to each side of the receptacle box 20 and the metal ring is sleeved on the cable to achieve the sliding connection.

In other embodiments, only one cable may be provided and the jackbox 20 is slidably connected to a single cable, but this connection may cause the jackbox to slide up and down and rotate in the horizontal plane with the waves, which is undesirable.

It is easily conceivable to provide three or more cables and to have the jackbox slidably connected to all the cables for further improving jackbox stabilization, but this construction correspondingly increases overall costs.

In alternative embodiments, the weight 13 may be made of concrete, cast iron, large scrap, or other materials commonly used in docks.

The outlet box 20 is used to realize power and communication connection with the ship, and the outlet box 20 may include power outlets, communication outlets, etc. as required, and the number of the outlets is set as required, which is not limited in this embodiment.

A buoyancy device 40 is fixed to the bottom of the receptacle box 20, and the buoyancy device 40 may be a float used to float the box body 22 on the water surface to prevent the receptacle box 20 from falling into the water when traction is lost. The inner part of the float bowl is provided with a cavity for providing buoyancy, and the material of the float bowl can be plastic and other materials with light weight, low cost and long service life. In other embodiments, the buoyancy device 40 may be made of foam or the like.

The buoyancy device 40 at the bottom of the socket box 20 can prevent the socket box from falling into water due to system failure or other reasons, but considering that the water area of the wharf is relatively wide and the storm is relatively large, a layer of waterproof cloth-like material can be arranged around the socket box 20 to surround the socket box, so that the damage caused by the fact that water enters the socket box due to storm is prevented, and meanwhile, the socket box 20 can be normally used under the condition of rainwater.

The bottom of the weight 13 protrudes downward with a fixing pin 14, and the fixing pin 14 can be inserted into the soil and sand on the water bottom to fix the weight 13 on the water bottom.

In the preferred embodiment, there are two fixed needles 14, with the two needles being juxtaposed. The fixing pin 14 may be in the shape of a metal rod extending in a vertical direction, and a pointed head is formed at a bottom end thereof.

In other embodiments, the number of the fixing pins can be set to one or more than two, and the fixing pins can be shaped to be an irregular shape similar to a boat anchor shape so as to improve the fixing effect.

Referring to fig. 1, in the first embodiment, the lifting device 30 includes a cable drum 31 fixed on the dock shore platform and a fixed pulley 32, the cable drum 31 is wound with a cable 33, the cable 33 is electrically connected with the socket box 20 after passing through the fixed pulley 31 on the platform, and the number of the correspondingly connected cables 33 is determined according to the requirement.

In this embodiment, the cable reel 31 can rotate to raise or lower the receptacle box 20. The cable drum 31 may be rotated manually or may be driven by a motor. By controlling the cable drum 31, the distance between the jackbox 20 and the water surface can be adjusted.

In order to realize intelligent control of the lifting device, a water level sensor (not shown) may be further provided, and the water level sensor is in communication connection with the control system of the cable drum 31, and the control system controls the lifting of the receptacle box 20 according to a water level signal provided by the water level sensor.

In other embodiments, the rotation of the cable drum 31 may be controlled by remote control or the like.

Referring to fig. 2, a lifting socket 200 for a wharf according to a second embodiment of the present invention, a lifting device 30a includes a cable 31a and a cable weight 32a, one end of the cable 31a is fixed to a supporting point 33a (fixed to a wharf platform), and the other end is electrically connected to a socket box 20a via a fixed pulley 34a, and the cable weight 32a acts on the cable 31a between the supporting point 33a and the fixed pulley 34a and keeps the cable 31a in a tightened state.

In this embodiment, the weight of the cable weight 32a should be less than the overall weight of the receptacle box 20a, so that the receptacle box 20a cannot be taken out of the water while the cable 31a is kept taut. When the water surface rises, the cable weight 32a moves downwards to keep the cable 31a in a tensioned state; when the water level drops, the receptacle box 20a moves down with the water level and pulls the cable weight 32a up while keeping the cable 31a under tension.

Furthermore, the lifting device 30a further includes a movable pulley 35a, the cable weight 32a is suspended below the movable pulley 35a, and the movable pulley 35a is slidably disposed on the cable 31 a. When the receptacle box 20a floats up and down along the water surface, the cable weight 32a can also slide laterally on the cable 31a via the movable pulley 35 a.

In this embodiment, the receptacle box 20a and the buoyancy device 40a are always located on the water surface, and other structures are the same as those of the first embodiment, and are not described again.

The foregoing descriptions of specific exemplary embodiments of the present invention have been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain certain principles of the invention and its practical application to enable one skilled in the art to make and use various exemplary embodiments of the invention and various alternatives and modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the claims and their equivalents.
