Description

Technical Field

[0001] The invention relates to the technical field of ship shore power, in particular to a fully automatic shore power plug protection and automatic plugging and unplugging device. Background Art

[0002] New energy port ship shore power (hereinafter referred to as ship shore power) means that when the ship stops using the generator set on board while berthing at the terminal, the ventilation system, drainage system, lighting system, refrigeration system and other equipment on board are powered by the electricity provided by the terminal. Ship shore power has the advantages of energy saving, emission reduction, noise reduction, shock absorption, and environmental protection. It is one of the typical "electricity instead of oil" electricity replacement methods. It is a key core technology to achieve energy conservation at berthing ports and terminals. It is an effective method to establish "green ports and terminals" and low-carbon ports and terminals. It represents an important direction for the construction and development of new types of ports in the future. my country has issued a series of policies to achieve green ports, but due to the lack of equipment and a series of technologies, ship shore power technology is still in its infancy.

[0003] The ship shore power system is mainly composed of four parts: public power grid / substation system, shore-based power supply (transformer) system, cable connection system, and ship-borne power receiving (transformer and conversion) system. It involves many key technologies such as high-voltage dual-frequency power supply, dynamic harmonic suppression and compensation, ship connection mode and special equipment research and development. In the cable connection system, it is divided into two types: shore-ship connection system and ship-shore connection system. Shore-ship type means that the shore power plug is lifted to a specified height by a lifting device on the shore side and manually inserted into the shore power box on the ship side; ship-shore type means that the shore power plug is lowered from the ship side, and the plug is manually grabbed on the shore side and inserted into the shore power box on the shore side. Among them, the traditional ship-shore connection system requires multiple people to complete the actions of grabbing the plug, taking off the protective cover, and inserting it into the shore power box on the shore side due to the thick shore power plug and cable line. Since the ship-shore connection system does not require the lifting device to provide additional kinetic energy, it is more widely used in my country than the shore-ship connection system. However, there are the following shortcomings: first, multiple people are needed to complete the work at the same time, which requires a high manpower; second, the efficiency is low, and the process is complicated, time-consuming and labor-intensive; third, the protective cover only plays a role in preventing the plug from colliding, and its utilization is not sufficient; fourth, after charging is completed, manual operation is still required to repeat the process of connecting and unplugging the plug, doubling the workload. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and propose a fully automatic shore power plug protection and automatic plug-in device. It is intended to achieve intelligent, unmanned, and precise control of cable transportation, improve power supply efficiency, and achieve the following technical objectives: First, the shore power plug protection device needs to be waterproof when not in use; second, during the connection process of the shore power plug, the connection between the shore power plug and the shore power box needs to be completely exposed; third, after charging, the shore power plug needs to be completely wrapped to meet the basic waterproof requirements; fourth, when the fluctuations between the ship and the shore are large, the shore power plug needs to be forcibly separated from the shore power box on the shore.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A fully automatic shore power plug protection and automatic plug-in device, comprising a shore power box, a track, a linear module, a plug protection device, and an automatic plug-in device, wherein

The ball slider block is fixed in the plug-in housing, the connecting plate is fixed on the ball slider, the spring is placed in the spring groove of the ball slider, a part of the ball is located at the end of the spring groove, and the other part is embedded in the corresponding groove of the ball slider block. The ball is pressed tightly by the spring in the ball slider, and the plug-in housing is installed on the linear module.

[0008] One end of the linear module leads to the shore power box on the shore side, and the track is placed at one end of the linear module close to the shore power box on the shore side, and the track is in a gradually widening "eight" shape;

[0009] The plug protection device includes a marker, a protective shell, a torsion hinge, a bottom wheel, an opening and closing flap, and a shore power plug. The marker is fixed to the outside of the protective shell, and the two opening and closing flaps are hinged to the protective shell through torsion hinges respectively. Each opening and closing flap is equipped with a bottom wheel. The shore power plug is partially installed in the protective shell. When the two opening and closing flaps are in a closed state under the action of the torsion hinge, the opening and closing flaps and the protective shell completely seal the shore power plug. The protective shell is placed on the protective device fixing block, and the bottom wheels of the opening and closing flaps span across both sides of the track. When the plug protection device follows the automatic plug-in device and approaches the shore power box on the shore along the track, the two opening and closing flaps open under the action of the track, exposing the shore power plug therein.

[0010] Preferably, a fixing rod is provided outside the protective shell, the marker is fixed on the fixing rod, and a snap mechanism for locking the plug protective device is provided on the protective device fixing block, and the fixing rod can be locked by the snap structure of the protective device fixing block.

[0011] Preferably, a plug fixing plate is provided in the protective shell, and the shore power plug is installed on the plug fixing plate.

[0012] Preferably, an upper baffle is installed on the shore power box on the shore side, and the upper baffle is used to assist in limiting the shore power plug to be connected.

[0013] Preferably, a module connecting plate is provided at the bottom of the plug-in housing, and the module connecting plate is fixed on the linear module.

[0014] Preferably, the shape of the marker is spherical, the number of the marker is 4 or more, and the marker is used to identify and calculate the position of the plug protection device within the field of view through an industrial computer or an industrial camera.

[0015] Preferably, under normal conditions, the plug protection device and the protection device fixing block and the bead slider in the automatic plug-in and unplug device are stuck and fixed by the bead. When the fluctuations between the ship and the shore are large, the cable pulls the plug protection device. When the force applied to the bead slider is too large, the bead further compresses the spring, and the bead completely enters the bead block. The plug protection device, the bead slider, the connecting plate, the protection device fixing block, the plug-in and unplugging housing, and the bead block are separated, so that the plug protection device follows the shore power plug away from the shore power box, thereby realizing the plug protection process in special circumstances.

[0016] After adopting the above technical scheme, the present invention combines a ball spring, a torsion spring hinge, a linear module, etc. to provide a plug protection device, which effectively prevents the shore power plug from being corroded by corrosive liquids such as seawater and rainwater on the ship, and at the same time satisfies the requirements of automatically opening when inserted and automatically closing when unplugged. An automatic plug-in and pull-out device is also designed. After the plug protection device is placed and fixed on it, it can be automatically inserted into the shore power box, and it will be automatically unplugged from the shore power box after charging is completed. It can also avoid important equipment being damaged in windy and rough weather, resulting in casualties and other accidents. The safety and automation level of the shore power plug plug-in and plug-out process are significantly improved, and the life of the shore power plug and shore power box is extended.
