Specific embodiments

[0021] In order to make the purpose, technical solutions and advantages of the present utility model clearer and more understandable, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] In the construction of offshore photovoltaic power generation projects, offshore photovoltaic trusses are composed of rods, bolt balls and bolts connecting the two. Among them, the bolts used to connect the rods and bolt balls are a very important component. For the convenience of transportation and part storage during factory production, the bolts are placed inside the rods. During the assembly process of the rods and bolt balls of the offshore photovoltaic truss, workers usually use simple devices such as wire loops to take out the bolts in the rods, and then carry out the assembly of the rods and bolt balls. However, the process of taking out the bolts takes a long time. There is a currently disclosed screw extraction device that is threadedly connected to the screw after the internal telescopic mechanism extends, and then the screw is taken out by retracting the telescopic mechanism after fixing the outside. The use of this device has the risk that the bolts in the rods of the offshore photovoltaic truss are pushed deeper and are more difficult to take out, which is time-consuming and laborious and there is a risk of not being able to take them out.

[0023] The present utility model provides an extraction device 100, which is applied to the extraction of bolts in the rods of the offshore photovoltaic truss 200.

[0024] As Figures 1 to 4 shown, the extraction device 100 includes a fixing mechanism 10, a hole-entry mechanism 20 and a telescopic mechanism 30. The fixing mechanism 10 is used to connect the end of the rod and the fixing mechanism 10 is provided with a through channel. One end of the hole-entry mechanism 20 is connected to the telescopic end of the telescopic mechanism 30, and the other end is provided with a magnetic suction head 21. The hole-entry mechanism 20 is arranged in the through channel. The telescopic mechanism 30 drives the hole-entry mechanism 20 to expand and contract, so that the magnetic suction head 21 magnetically sucks the bolt and takes it out.

[0025] The extraction device 100 of the present utility model is applied to the extraction of bolts in the members of the offshore photovoltaic truss 200, and includes a fixing mechanism 10, a hole entering mechanism 20, and a telescopic mechanism 30. The fixing mechanism 10 is used to connect the end of the member, and the fixing mechanism 10 is provided with a through channel. One end of the hole entering mechanism 20 is connected to the telescopic end of the telescopic mechanism 30, and the other end is provided with a magnetic suction head 21. The hole entering mechanism 20 is inserted into the channel, and the telescopic mechanism 30 drives the hole entering mechanism 20 to expand and contract. The extraction device 100 can use the magnetic suction head 21 to magnetically attract and extract the bolt, so as to magnetically complete the one-time rapid extraction of the bolt in the member of the offshore photovoltaic truss 200, avoid the risk of being unable to extract, improve work efficiency, and shorten the construction period of the offshore photovoltaic project.

[0026] Referring to Figure 1 and Figure 2 As shown, optionally, the fixing mechanism 10 includes a fixing component 11 and an adjusting component 13. The fixing component 11 forms a channel, and the adjusting component 13 is arranged on the outer periphery of the fixing component 11; the member is provided with a hole 20A for accommodating the bolt, and the adjusting component 13 is clamped at the opening of the hole 20A, so that the channel is aligned and communicated with the hole 20A.

[0027] In this embodiment, the fixing component 11 is used to provide a channel, and the adjusting component 13 located on the outer periphery of the fixing component 11 is used to connect with the member of the offshore photovoltaic truss 200, so that the channel of the entire extraction device 100 can be aligned and communicated with the hole 20A of the member, improving the stability and straight-throughness of the bolt extraction path, so that the hole entering mechanism 20 can directly penetrate into the hole 20A along the channel to extract the bolt in the hole 20A.

[0028] Optionally, the fixing component 11 includes a fixing piece 111 and a limiting plate 112. The fixing piece 111 is annular, the adjusting component 13 is arranged on the outer side of the ring of the fixing piece 111, the limiting plate 112 is arranged on the inner side of the ring of the fixing piece 111, both ends of the limiting plate 112 are connected end to end, and one end of the limiting plate 112 extends to form a channel.

[0029] In this embodiment, the limiting plate 112 located inside the annular fixing piece 111 is connected end to end to form a hollow columnar structure, one end of which is fixed to the fixing piece 111, and the other end extends to form a channel with a certain length. The extending direction can be from the fixing piece 111 into the hole 20A of the member, or can extend away from the member, both of which can form the channel. The setting of the channel with a certain length makes the extending direction of the hole entering mechanism 20 parallel to the extending direction of the member or the channel, ensuring the linearity of the bolt extraction process, avoiding the blockage caused by the skew of the hole entering mechanism 20, and improving the bolt extraction efficiency.

[0030] Optionally, both the fixing piece 111 and the limiting plate 112 are made of anti-magnetic materials to avoid the magnetic field interference of the materials of the fixing piece 111 and the limiting plate 112 on the travel path of the magnetic suction head 21.

[0031] Optionally, three adjusting components 13 are provided. The three adjusting components 13 are evenly spaced around the outer periphery of the fixing component 11 to improve the centering degree of the fixing component 11 and ensure the stability of the bolt removal path.

[0032] Optionally, the adjusting component 13 includes a connecting member 131 and an adjusting member 132. The connecting member 131 is connected to the fixing component 11, the adjusting member 132 is connected to the connecting member 131, and the outer end of the adjusting member 132 is used to abut against the end opening of the rod member.

[0033] In this embodiment, the connecting member 131 is used to connect the fixing component 11, specifically connected to the fixing plate of the fixing component 11. One end of the adjusting member 132 is connected to the connecting member 131, and the other end is used to abut against the end opening of the rod member, that is, abut against the opening of the hole 20A.

[0034] Specifically, the adjusting member 132 has an abutting surface and an outer edge surface at a certain angle. The abutting surface is used to abut against the inner side wall of the opening of the hole 20A, and the outer edge surface is used to overlap on the outer end surface of the opening of the hole 20A, that is, the outer edge surface overlaps on the end surface of the rod member. The abutting surface and the outer edge surface cooperate to improve the relative fixing stability between the fixing mechanism 10 and the rod member.

[0035] Optionally, the adjusting member 132 is set as a telescopic elastic member, or the adjusting member 132 is a block structure with a spring at one end, and the other end of the spring is connected to the connecting member 131.

[0036] In this embodiment, the adjusting member 132 can adjust its length so that the extraction device 100 can be applicable to rod members in holes 20A within a certain diameter range, improving the versatility of the extraction device 100. Among them, one way to adjust the length can be that the adjusting member 132 itself is set as an elastic member, exemplarily a rubber structure with elasticity. Or, the adjusting member 132 is a block structure with a spring at one end, and the other end of the spring is connected to the connecting member 131. Both of the above two adjusting members 132 can be provided with an abutting surface and an outer edge surface, improving the versatility while ensuring reliable abutment.

[0037] Optionally, the fixing component 11 is provided with an avoidance hole (not shown in the figure) communicating with the channel. The connecting member 131 is provided with balls inside, and the diameter of the balls is larger than the aperture of the avoidance hole. Part of the balls extend into the channel from the avoidance hole.

[0038] In this embodiment, the avoidance hole can be a through hole opened on the fixing member 111 and the limiting plate 112. The diameter of the balls is larger than the aperture of the avoidance hole, which can enable part of the balls to extend into the channel from the avoidance hole, thereby improving the smoothness of the hole entering mechanism 20 moving up and down in the channel, and also avoiding the hole entering mechanism 20 from being skewed and causing obstruction during extraction, improving the bolt extraction efficiency.

[0039] Combined withFigure 1 and Figure 3 As shown in Figure 3 , optionally, the hole entering mechanism 20 includes a connecting rod 22 and a magnetic head 21 provided at one end of the connecting rod 22. The other end of the connecting rod 22 is connected to the telescopic mechanism 30. The connecting rod 22 is made of a diamagnetic material to avoid magnetic field interference caused by the material of the connecting rod 22 on the travel path of the magnetic head 21.

[0040] In this embodiment, the magnetic head 21 can be set as an energizable Halbach array magnet. Among them, the energizable Halbach array magnet includes a magnetic core, an outer protective layer of the magnetic core (no protective layer is provided at the port of the magnetic core), and a battery. The lower side of the connecting rod 22 is connected to the magnetic core, and the upper side is connected to the telescopic mechanism 30. The middle part of the connecting rod 22 is slidably connected to the inner side of the channel of the fixing mechanism 10. The outer protective layer of the magnetic core (no protective layer is provided at the port of the magnetic core) can avoid shaking caused by attracting surrounding rods. The diameter of the energized electromagnet is smaller than the aperture of the members of the offshore photovoltaic truss 200.

[0041] Referring to Figure 1 and Figure 4 As shown in Figure 4 , optionally, the telescopic mechanism 30 is set as an electric telescopic rod and is provided with an electric button.

[0042] In this embodiment, the telescopic mechanism 30 is an electric telescopic rod. The electric telescopic rod includes a telescopic sleeve 32, a handle 31, and a power-on button 33. One end of the telescopic sleeve 32 is connected to the end of the connecting rod 22 of the hole entering mechanism 20 away from the magnetic head 21, and the other end of the telescopic sleeve 32 is connected to the handle 31. The handle 31 is provided with a switch button for the energizable Halbach array magnet, and the power-on button 33 controls the magnitude of the attractive force of the Halbach array magnet. The diameter of the telescopic sleeve 32 is smaller than the aperture of the members of the offshore photovoltaic truss 200.

[0043] When the extraction device 100 performs the operation of extracting bolts, the entire fixing mechanism 10 is abutted against the end face of the member through the outer edge part of the adjusting member 132 in the fixing mechanism 10, which is convenient for path fixing during the process of extracting bolts and avoids the situation that the hole entering mechanism 20 shakes due to the force of the truss member material on the magnet. Then, the telescopic mechanism 30 is used to move the Halbach array magnet into the hole 20A of the member. When the magnet contacts the bolt inside the member, press the power-on button 33 to increase the attractive force of the magnet, so as to adsorb the bolt inside the member, and then pull out the entire mechanism until the bolt inside the member is taken out from the port of the member. The telescopic mechanism 30 is also convenient for extracting bolts deep inside the members of the offshore photovoltaic truss 200, increasing the operation flexibility of the entire mechanism.

[0044] After completing the operation of removing a bolt, the button can be released to reduce the magnetic attraction of the magnet and then release the fixing mechanism 10. Then, the operation of removing the bolt inside the next truss member can be carried out. The operation process of the present utility model is simple and flexible, improving the working efficiency of workers and shortening the construction period of the project.
