Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic module installation technology, specifically a crane for installing marine photovoltaic modules. Background Technology

[0002] Offshore photovoltaic (PV) modules are the core components of offshore power generation systems. When in operation, these modules convert solar energy into electrical energy, which is then fed into the power grid to power equipment, providing clean energy. However, the installation of offshore PV modules requires the use of cranes. At seaside locations, seawater contains a large amount of salt and other corrosive substances. Prolonged contact with seawater causes electrochemical corrosion of the crane chains, especially at the interface between seawater and air, where the corrosion may be more severe due to oxygen concentration differences. Therefore, cleaning the crane chains is essential. To overcome these shortcomings, existing technology (Chinese patent application No. 201621155781.2, filed on 2016-10-31) describes a port crane with a weighing alarm function. This function prevents operators from damaging the crane due to improper operation, protects the wire ropes, extends their service life, and prevents them from rusting and breaking due to seawater corrosion. The structure is simple and easy to promote.

[0003] However, simply protecting the lifting chain during its use is far from sufficient. The port crane mentioned in the above application lacks a structure for cleaning the lifting chain during operation, which still causes severe corrosion to the lifting chain, shortening its service life and causing unnecessary trouble for the crane and the lifting chain. Utility Model Content

[0004] The purpose of this utility model is to provide a crane for installing offshore photovoltaic modules, in order to solve the problem mentioned in the background art that, during operation, the lack of a structure for cleaning the lifting chain still causes severe corrosion of the lifting chain, shortening its service life and bringing unnecessary trouble to the operation of the crane and the lifting chain.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crane for installing offshore photovoltaic modules, comprising a body, the interior of which is connected to a lifting chain via a winding machine, and a working plate is bolted to the lower surface of the body, and a motor is bolted to the right side surface of the working plate, with a circular plate fixedly connected to the output end of the motor via a coupling; a working frame is movably connected to the left side of the working plate, and a lower connecting plate is bolted to the lower surface of the working frame, with a cleaning plate slidably disposed inside the lower connecting plate; a second magnet is fixedly connected to the end of the cleaning plate; the upper left side of the working plate is convex, and an airbag is adhered to the lower surface of the convex position of the working plate, with a jet pipe fixedly connected to the left side of the airbag.

[0006] Preferably, a protrusion is fixedly connected to the surface of the circular plate, and the working frame is sleeved and connected to the surface of the protrusion, and a long pin is fixedly connected to the surface of the working plate.

[0007] Preferably, a column is fixedly connected to the inner wall of the lower plate, and the columns are symmetrically distributed on both sides of the lower plate. The columns correspond one-to-one with the long pins, and the columns penetrate the interior of the long pins.

[0008] Preferably, the lower left side of the working plate is convex, and a first magnet is fixedly connected to the end of the convex position on the lower left side of the working plate.

[0009] Preferably, the cleaning plates are symmetrically distributed on both sides of the lower plate, and the brushes on the surface of the cleaning plates are in contact with the hanging chain, and the magnetic poles at the end of the second magnet are opposite to the magnetic poles on the surface of the first magnet.

[0010] Preferably, the outer wall of the cleaning plate is convex, and a connecting spring that plays an elastic restoring role is fixedly connected to the convex position of the outer wall of the cleaning plate, and the other side of the connecting spring is fixedly connected to the surface of the lower plate.

[0011] Preferably, a compression plate is fixedly connected to the upper surface of the working frame, an air inlet pipe is fixedly connected to the upper surface of the airbag, and a one-way valve is fixedly connected to the surface of both the air inlet pipe and the surface of the jet pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the crane for installing offshore photovoltaic modules adopts a novel structural design, the specific details of which are as follows: During operation, the crane used for installing offshore photovoltaic modules can start the motor on the surface of the working plate. When the motor is working, the circular plate and the protrusion rotate. At this time, the working frame, the lower plate and the cleaning plate make reciprocating linear motion in the vertical direction. In this way, the cleaning plate can clean the lifting chain, so that no seawater remains on the surface of the lifting chain, avoiding corrosion of the lifting chain and extending the service life of the lifting chain.

[0013] Furthermore, the long pin and column make the movement of the lower plate more stable when it moves.

[0014] When the bottom plate and cleaning plate of the offshore photovoltaic module installation crane move vertically, the first magnet at the end of the cleaning plate will intermittently approach the second magnet. At this time, under the action of mutual magnetic attraction and connecting spring, the cleaning plate will make reciprocating linear motion in the horizontal direction. Thus, the cleaning plate moves not only in the vertical direction but also in the horizontal direction, which optimizes the cleaning effect of the hanging chain and reduces the amount of seawater remaining on the surface of the hanging chain.

[0015] Furthermore, cleaning plates are distributed on both sides of the chain, allowing for a more thorough cleaning of the chain.

[0016] (3) When the working frame of the crane used for installing the offshore photovoltaic module moves, it will drive the extrusion plate to move in the vertical direction. At this time, the extrusion plate will intermittently extrude the airbag, and the airbag will intermittently blow air to clean the chain through the jet pipe. At this time, the impurities remaining on the surface of the chain will also be cleaned. Therefore, under the multiple cleaning structure, the surface of the chain will not have seawater and impurities remaining, thereby reducing the probability of the chain being corroded and greatly extending the service life of the chain.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides the following technical solution: a crane for installing offshore photovoltaic modules.

[0021] Example 1: The cleaning plate 9 can move vertically to clean the suspension chain, such as... Figures 1-4As shown, the machine includes a body 1, with a winding machine connecting to a hanging chain inside the body 1. A work plate 2 is bolted to the lower surface of the body 1, and a motor is bolted to the right side surface of the work plate 2. A circular plate 3 is fixedly connected to the output end of the motor via a coupling. A work frame 5 is movably connected to the left side of the work plate 2. The work frame 5 is fitted onto the work plate 2 via a linear bearing, thus forming a linear motion pair in the vertical direction. A lower plate 6 is bolted to the lower surface of the work frame 5, and a cleaning plate 9 is slidably installed inside the lower plate 6. A protrusion 4 is fixedly connected to the surface of the circular plate 3, and the protrusion 4 slides in contact with the inner groove of the work frame 5. A long pin 7 is fixedly connected to the surface of the work plate 2. A column 8 is fixedly connected to the inner wall of the lower plate 6, and the columns 8 are symmetrically distributed on both sides of the lower plate 6. Each column 8 corresponds to a long pin 7, and the column 8 passes through the interior of the long pin 7, thus forming a linear motion pair in the vertical direction of the lower plate 6.

[0022] During use, the motor on the surface of the working plate 2 can be started. When the motor is working, the circular plate 3 and the protrusion 4 rotate. At this time, the working frame 5, the lower plate 6 and the cleaning plate 9 are in a moving state. The long pin 7 and the column 8 make the working frame 5 and the lower plate 6 move only in the vertical direction. At this time, the working frame 5 and the cleaning plate 9 make reciprocating linear motion in the vertical direction. Thus, the cleaning plate 9 can clean the hanging chain, so that no seawater remains on the surface of the hanging chain, avoiding corrosion of the hanging chain and extending the service life of the hanging chain.

[0023] Example 2: Unlike Example 1, by using the first magnet 10, the second magnet 11, and the connecting spring 12, the cleaning plate 9 can reciprocate linearly in the horizontal direction, thus optimizing the cleaning effect. Figure 5 As shown, a second magnet 11 is fixedly connected to the end of the cleaning plate 9; the lower left side of the working plate 2 is raised, and a first magnet 10 is fixedly connected to the end of the raised position on the lower left side of the working plate 2; the cleaning plates 9 are symmetrically distributed on both sides of the lower connecting plate 6; the brush on the surface of the cleaning plate 9 is attached to the hanging chain; the magnetic pole at the end of the second magnet 11 is opposite to the magnetic pole on the surface of the first magnet 10; the cleaning plate 9 is horizontally movable inside the lower connecting plate 6.

[0024] The outer wall of the cleaning plate 9 is raised, and a connecting spring 12 that plays an elastic reset role is fixedly connected to the raised position of the outer wall of the cleaning plate 9. The other side of the connecting spring 12 is fixedly connected to the surface of the lower plate 6.

[0025] When the cleaning plate 9 moves vertically, the first magnet 10 on the surface of the cleaning plate 9 will intermittently approach the second magnet 11. When the first magnet 10 approaches the second magnet 11, the cleaning plate 9 will move towards the direction of squeezing the connecting spring 12 under the action of mutual magnetic attraction. When the first magnet 10 moves back away from the second magnet 11, the cleaning plate 9 will move back under the action of the connecting spring 12. The above process is repeated. The cleaning plate 9 reciprocates in the horizontal direction inside the lower plate 6. At this time, the cleaning plate 9 can better clean the hanging chain and optimize the cleaning effect.

[0026] Example 3: Unlike Example 2, the air jet pipe 15 can clean impurities from the surface of the hanging chain, such as... Figure 6 As shown, the upper left side of the working plate 2 is raised, and an airbag 14 is bonded to the lower surface of the raised part of the working plate 2. An air jet pipe 15 is fixedly connected to the left side of the airbag 14. An extrusion plate 13 is fixedly connected to the upper surface of the working frame 5. An air inlet pipe is fixedly connected to the upper surface of the airbag 14. A one-way valve is fixedly connected to the surface of the air inlet pipe and the surface of the air jet pipe 15.

[0027] When the working frame 5 moves, it drives the extrusion plate 13 to move vertically. At this time, the extrusion plate 13 will intermittently extrude airbag 14. When the airbag 14 is extruded, it blows air through the jet pipe 15. When the airbag 14 is not extruded, it inhales air through the air inlet pipe. As a result, the airbag 14 will intermittently blow air through the jet pipe 15 to clean the chain. At this time, the impurities remaining on the surface of the chain are also cleaned. Therefore, under the multi-cleaning structure, the surface of the chain will not have seawater and impurities remaining, which reduces the probability of the chain being corroded and greatly extends the service life of the chain. When the airbag 14 and the jet pipe 15 are working, the one-way valve makes the airflow direction from the air inlet pipe to the jet pipe 15, and there will be no backflow, which ensures the stability of the airbag 14.

[0028] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
