Description

Technical Field

[0001] The utility model relates to the field of ship shore power systems, in particular to an erection structure of ship shore power cables. Background Art

[0002] Ship shore power cable is a cable that connects the ship and the shore power supply. It allows the ship to access the shore power system when docked at the pier, thereby shutting down its own generator. The use of shore power system can not only reduce the noise and air pollution generated by ships when operating in ports, but also significantly reduce the air pollution in port cities. Therefore, ship shore power cable is one of the important measures to promote the green and low-carbon development of ports. With the increasing attention paid to environmental protection, ship shore power technology has been widely used and promoted.

[0003] When a ship docks at a port, in order to reduce the impact between the ship and the dock, the dock usually installs a buffer elastic pad. The use of the buffer elastic pad will form a certain gap between the ship and the dock. At the same time, due to the ups and downs of the tide, the effects of wind and swells, and the tilt of the ship during loading and unloading, the length of the cable must be constantly adjusted to adapt to these continuous changes. In addition, as the cargo load on the ship changes, the vertical distance between the cable and the sea level will also change. Therefore, in order to meet the challenges brought by these complex factors, the laying length of the cable needs to be preset to the maximum value so that it can adapt to various dynamic changes without an automatic tightening device.

[0004] However, when the cable is too long, the excess cable may sag into the gap between the ship and the dock due to gravity, increasing the risk of cable leakage or even electric shock. Utility Model Content

[0005] The embodiment of the present application provides a structure for installing a ship shore power cable to solve the technical problem in the prior art that the cable of the shore power cable is easily submerged in water in the absence of an automatic tightening device, thereby reducing safety hazards.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: a ship shore power cable installation structure, including a base, a vertical support is installed on the base, the vertical support includes a lower support connected to the base and an upper support that can be telescopic relative to the lower support, a transverse support is installed at the upper end of the upper support, the transverse support includes at least two sections of telescopic sleeves, a roller is installed on the lower side of each section of the sleeve, and the outer periphery of the roller is provided with a groove matching the cable.

[0007] When the device is in use, the front end of the lateral support extends toward the shore power supply box, and the cable is laid on the lateral support. Since rollers are installed on the lower side of the lateral support, the grooves of the rollers can cooperate with the cables, thereby supporting the cables. At the same time, the height of the vertical support can also be adjusted. Therefore, when the cable is too long, it can effectively prevent the cable from entering water, reducing safety hazards.

[0008] Furthermore, the rear end of the lateral support is hinged to the upper end of the vertical support; the bottom of the lateral support is also hinged with a hydraulic strut, and the other end of the hydraulic strut is hinged to one side of the upper support; by controlling the extension and retraction of the hydraulic strut, the angle of the lateral support can be adjusted, so that the device can adapt to the changes in the gap between the ship and the dock, avoiding safety risks caused by cable sagging.

[0009] Furthermore, hinge supports are fixed to the bottom of the lateral support and one side of the upper support, and both ends of the hydraulic strut are connected to the hinge supports.

[0010] Furthermore, the installation position of the bottom hinge support of the lateral support is biased towards one side of the lateral support, and correspondingly, the installation position of the upper hinge support of the upper support is biased towards one side of the upper support.

[0011] Furthermore, two vertical plates are provided at the upper end of the upper support, a guide wheel is installed between the two vertical plates, and a groove matching with the cable is provided on the outer periphery of the guide wheel.

[0012] Furthermore, the base includes a fixed seat and a rotating seat rotatably installed above the fixed seat, a notch is provided on one side of the fixed seat, and a stopper is provided at the bottom of the rotating seat, and the stopper is located in the notch of the fixed seat.

[0013] It can be seen from the above technical solutions that the utility model has at least the following technical effects or advantages:

[0014] When the device is in use, the front end of the lateral support extends toward the shore power supply box, and the cable is laid on the lateral support. Since rollers are installed on the lower side of the lateral support, the grooves of the rollers can cooperate with the cables, thereby supporting the cables. At the same time, the height of the vertical support can also be adjusted. Therefore, when the cable is too long, it can effectively prevent the cable from entering water, reducing safety hazards.

[0018] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0019] The utility model discloses a ship shore power cable installation structure, which comprises a base 1, a vertical support 2 and a transverse support 3, wherein the vertical support 2 is installed above the base 1, and the rear end of the transverse support 3 is installed at the upper end of the vertical support 2. When the device is in use, the front end of the transverse support 3 extends toward the shore power supply box, and the cable is installed on the transverse support 3, so as to prevent the cable from entering the water.

[0020] like Figure 1 As shown, the transverse support 3 includes at least two sections of sleeves, wherein the outermost sleeve is connected to the upper end of the vertical support 2, and the other sleeves are embedded in the inner part of the outermost sleeve and can be extended and retracted relative to the outer sleeve. Among them, the telescopic structure and working principle of the transverse support 3 are prior art and will not be repeated here. In this embodiment, the inner sleeve of the transverse support 3 can be directly driven by hydraulic pressure or pneumatic pressure. In other embodiments, a telescopic cylinder is installed on the outside of the transverse support 3, and the telescopic cylinder can be installed on one side of the transverse support 3. The two ends of the telescopic cylinder are respectively fixed to the innermost sleeve and the outermost sleeve, so that when the telescopic cylinder is extended and retracted, the transverse support 3 can be driven to extend and retract synchronously. Since the transverse support 3 is retractable, when the device is not in use, the transverse support 3 can be shortened to the shortest, and when the device is in use, the transverse support 3 can be extended, which has high flexibility and applicability.

[0021] In addition, a roller 4 is installed on the lower side of each section of the sleeve, and the roller 4 is located at the front end of each section of the sleeve, so that when the sleeve is extended, the roller 4 can be extended synchronously. The left and right sides of the roller 4 are rotatably mounted on a support, and the upper end of the support is fixed to the bottom end of the sleeve. The outer periphery of the roller 4 is also provided with a groove, and the groove can cooperate with the cable. The cable is laid above the roller 4 and is located in the groove. One end of the cable is relatively fixed to the frontmost sleeve, so that when the lateral support 3 is extended, the roller 4 can support the cable while keeping the rotation of the roller 4.

[0022] In this embodiment, the rear end of the lateral support 3 and the connection point of the vertical support 2 are connected together in a hinged manner. Figure 1 As shown, the vertical support 2 includes a lower support 201 and an upper support 202. Among them, two vertical plates 5 are provided at the upper end of the upper support 202, and the rear end of the transverse support 3 is located between the two vertical plates 5 and connected to the two vertical plates 5 through a pin shaft. The bottom of the transverse support 3 is also hinged with a hydraulic support rod 6, and the other end of the hydraulic support rod 6 is connected to one side of the upper support, so that the angle adjustment of the transverse support 3 can be achieved by controlling the extension and contraction of the hydraulic support rod 6. Specifically, a hinge support is fixed at the bottom of the outer sleeve of the transverse support 3, and a hinge support is also installed on one side of the upper support 202, and the two ends of the hydraulic support rod 6 are respectively connected to the hinge support.

[0023] like Figure 1 As shown, a guide wheel 7 is also installed between the two vertical plates 5 at the upper end of the upper support, and a groove matching the cable is also provided on the outer periphery of the guide wheel 7, so that the cable can pass through the guide wheel 7 between the two vertical plates 5. During the extension of the lateral support 3, the guide wheel 7 is supported under the cable, which can effectively avoid damage to the cable. In addition, in this embodiment, the installation position of the hinge support at the bottom of the lateral support 3 is biased toward one side of the lateral support 3, and correspondingly, the installation position of the hinge support on the upper support 202 is also biased toward one side of the upper support 202. It should be understood that the two hinge supports are biased toward the same side of the lateral support 3 and the upper support 202. Therefore, when the two ends of the hydraulic strut 6 are respectively connected to the two hinge supports, the hydraulic strut 6 can be kept biased toward one side of the device, thereby avoiding interference of the hydraulic strut 6 with the cable.

[0024] On the other hand, in this embodiment, the upper support 202 of the vertical support 2 can be extended relative to the lower support 201. The extension principle can be referred to the hydraulic cylinder, which will not be described here. By the relative extension of the upper support 202 and the lower support 201, the height position of the lateral support 3 can be adjusted, thereby improving the applicability of the device. Figure 1As shown, the base 1 includes a fixed seat 101 and a rotating seat 102 rotatably installed above the fixed seat 101, a notch is provided on one side of the fixed seat 101, and a stopper 103 is provided at the bottom of the rotating seat 102, and the stopper 103 is located in the notch of the fixed seat 101, thereby enabling the vertical support 2 to rotate relative to the fixed seat 101 while keeping the rotation angle within a certain range.
