[0024] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0025] Please see Figure 1-6 According to an embodiment of the present invention, an auxiliary device for laying lightning protection metal mesh includes two opposing support plates 101, a mesh laying mechanism 2 is installed between the two support plates 101, opposing vertical plates 102 are vertically installed on one side of the two support plates 101, a pressure roller machine 3 is installed between the two vertical plates 102, and opposing assembly frames 114 are installed on opposing sides of the two support plates 101. The mesh laying mechanism 2 includes a winding roller 201, a first guide roller 202 and a second guide roller 203. The winding roller 201 is installed between the assembly frames 114 and can be disassembled. The first guide roller 202 is installed below the winding roller 201 away from the pressure roller machine 3 and is parallel to the winding roller 201 vertically. The second guide roller 203 is installed between the vertical plates 102 close to the pressure roller machine 3 and is horizontally aligned with the pressure roller machine 3. The metal mesh is wound into the winding roller 201, then guided into the second guide roller 203 by the first guide roller 202, and finally rolled by the pressure roller machine 3 so that the metal mesh adheres to the blade.

[0026] The pressure roller machine 3 includes a horizontal plate 301 and mounting brackets 308 disposed at both ends of the horizontal plate 301. Bases 302 are installed at both ends of the horizontal plate 301, and the mounting brackets 308 are fixedly installed on the bases 302. Two connecting plates 307 are symmetrically installed along the center of the horizontal plate 301. A first pressure roller 303 is installed between the connecting plate 307 and the adjacent mounting bracket 308. A second pressure roller 304 is also installed between the two connecting plates 307. The second pressure roller 304 is parallel to the second guide roller 203, and the first pressure roller 303 is inclined.

[0027] The mounting frame 308 has an adjustment hole 306, and the vertical plate 102 has a through hole 113. The mounting frame 308 is installed through the vertical plate 102. When the through hole 113 is aligned with the adjustment hole 306, a bolt can be passed through the through hole 113 and the adjustment hole 306 to fix the mounting frame 308. By changing the alignment of the adjustment hole 306 with the through hole 113, the position of the mounting frame 308 can be adjusted, and the height of the first pressure roller 303 and the second pressure roller 304 can be changed.

[0028] The adjusting hole 306 allows for vertical adjustment of the pressure roller 3. When the adjusting hole 306 is aligned with the through hole 113 on one side of the vertical plate 102, the adjusting hole 306 and the through hole 113 are connected together with a nut and fixed with bolts. At this time, the pressure roller 3 is fixed on the vertical plate 102. To change the position of the pressure roller 3, first remove the bolts and nuts, and then realign the adjusting hole 306 with the other through holes 113 on one side of the vertical plate 102. The mounting bracket 308 is snapped onto one end of the first pressure roller 303. The end of the first pressure roller 303 away from the mounting bracket 308 is connected to the connecting plate 307. The other end of the connecting plate 307 is connected to the second pressure roller 304. The first pressure roller 303 is in an inclined state and is symmetrical to the second pressure roller 304 with the midpoint as the symmetrical point. The second pressure roller 304 is parallel to the first guide roller 202.

[0029] In addition, the inner walls of both sides of the two support plates 101 are provided with sliding grooves 112, and lead screws 105 are provided in the two sliding grooves 112. A threaded sleeve 106 is screwed onto the outside of the lead screw 105, and a spring 115 is wound around the bottom of the lead screw 105. A slider 107 is also slidably disposed in the sliding grooves 112. One end of the slider 107 is connected to the spring 115. When the spring 115 is subjected to an external load, it contracts and deforms, storing deformation energy. Therefore, when the metal mesh is laid on the first guide roller 202, the slider 107 is subjected to force that compresses the spring 115 downwards, and the spring 115 generates an upward elastic force to tighten the metal mesh. The threaded sleeve 106 passes through the slider 107, and an insertion hole 108 is provided at the end of the slider 107 facing outwards from the sliding grooves 112. The shaft end of the first guide roller 202 is rotatably mounted in the insertion hole 108.

[0030] The slider 107 has an insertion hole 108 on one side, and the second guide roller 203 is rotatably connected in the insertion hole 108. The screw sleeve 106 can limit the slider 107. The support plate 101 is fixedly installed with a locking sleeve 103 at one end near the winding roller 201. A locking ring 111 is also provided inside the locking sleeve 103. A locking groove 110 is provided on the inner surface of the locking ring 111. A locking plate 109 is installed on the lead screw 105. The locking plate 109 is set through the lead screw 105. In this embodiment, the locking plate 109 is a cuboid. In other embodiments not shown, the locking plate 109 can also be any polygonal shape. The locking plate 109 is fixed by the locking sleeve 103. The projected area of ​​the locking plate 109 along the length direction of the lead screw 105 is smaller than the projected area of ​​the locking groove 110. The shape of the locking groove 110 is the same as that of the locking plate 109.

[0031] The lead screw 105 is fixed by the locking sleeve 103. A rotating handle 104 is provided on one side of the lead screw 105. When the locking plate 109 and the locking groove 110 are aligned, rotating the rotating handle 104 can pull the lead screw 105, thus releasing the lead screw 105 from locking and allowing it to be disassembled and replaced. When the locking plate 109 is inside the locking sleeve 103, rotating the rotating handle 104 will misalign the locking plate 109 with the locking groove 110. At this time, pulling the rotating handle 104 will not be able to pull the lead screw 105, thereby locking the lead screw 105 and preventing it from easily sliding out of the slide groove 112. When the first guide roller 202 is subjected to different forces depending on the size of the metal mesh, the spring 115 installed at the bottom of the slider 107 generates an upward elastic force under the action of external force, thereby supporting the slider 107 and adjusting the vertical position of the first guide roller 202.

[0032] The metal mesh is guided into the first guide roller 202 by the winding roller 201. When the metal mesh is laid on the second guide roller 203, the first guide roller 202 and the second guide roller 203 are subjected to the elastic force of the spring 115 in the groove 112, which can tighten the metal mesh. Finally, the second guide roller 203 drives the metal mesh to be laid on the pressure roller machine 3. At this time, the pressure roller machine 3 performs different rolling on the metal mesh, so that the metal mesh is laid into different shapes, allowing the metal mesh to adhere to the blade, which greatly reduces the workload while ensuring the adhesion between the metal mesh and the blade.

[0033] In use, firstly, rotate the rotating handle 104, which drives the lead screw 105, which is locked by the locking sleeve 103. Secondly, adjust the pressure roller 3 on the vertical plate 102. When the adjusting hole 306 is aligned with the through hole 113 on one side of the vertical plate 102, connect the adjusting hole 306 and the through hole 113 together with a nut and fix them with bolts. At this time, the pressure roller 3 is fixed on the vertical plate 102. Finally, lay the metal mesh on the first guide roller 202 through the winding roller 201. The first guide roller 202 drives the metal mesh to be laid on the second guide roller 203. The metal mesh is tightened under the action of elasticity. Then, the second guide roller 203 drives the metal mesh to be laid on the pressure roller 3. At this time, the pressure roller 3 rolls the metal mesh in different shapes, so that the metal mesh fits with the blade.
