[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] This invention provides a technical solution: a color steel plate for wind farms, comprising a steel plate body 1, two insert rods 3 fixedly connected to the steel plate body 1, a first hollow block 2 fixedly connected to the opposite side of the insert rods 3 on the steel plate body 1, the first hollow block 2 having insertion holes for cooperating with the two insert rods 3, and a sealing ring 21 for cooperating with the insert rods 3 fixedly connected to the insertion holes, a second hollow block 4 slidably connected inside the first hollow block 2, the outer wall of the second hollow block 4 fitting against the inner wall of the first hollow block 2, two rectangular plates 41 symmetrically slidably connected inside the second hollow block 4, the two rectangular plates 41 dividing the second hollow block 4 into two first cavities 42 and a second cavity 43, the second cavity 43 penetrating through the second... The top and bottom walls of the hollow block 4 have a combined thickness of two rectangular plates 41 that is greater than the width of the second cavity 43. Each of the two rectangular plates 41 is rotatably connected to a connecting rod 411. The end of the connecting rod 411 away from the rectangular plate 41 is rotatably connected to the first hollow block 2. Both sides of the first hollow block 2 are provided with vent holes that cooperate with the two first cavities 42 respectively. A first spring is placed inside the first hollow block 2. The two ends of the first spring abut against the first hollow block 2 and the second hollow block 4 respectively. The bottom of the first hollow block 2 is provided with a first one-way valve 23 for venting the gas inside the first hollow block 2. The bottom of the insert rod 3 is rotatably connected to a rotating plate 32. The bottom of the rotating plate 32 abuts against the second hollow block 4 intermittently.

[0027] Reference Figure 1 , Figure 2 and Figure 4 Take two steel plate bodies 1, and insert the two insert rods 3 on one steel plate body 1 into the corresponding insertion holes on the first hollow block 2 on the other steel plate body 1. Then, continue to apply pressure to the steel plate body 1 inserted into the first hollow block 2, so that the insert rods 3 continue to penetrate deeper into the first hollow block 2. At this time, when the insert rods 3 continue to be inserted into the second hollow block 4, the insert rods 3 apply pressure to the second hollow block 4 through the rotating plate 32, so that the second hollow block 4 overcomes the elastic force of the first spring and moves downward, thereby causing the two... The rectangular plate 41 and the second hollow block 4 move downwards synchronously. At this time, the connecting rod 411 is driven by the rectangular plate 41 to swing in an arc with the connection point with the first hollow block 2 as the center, and the swing direction is downward. As a result, the two rectangular plates 41 are pushed closer to each other by the connecting rod 411. Due to the setting of the vent hole, external air can enter into the two first cavities 42, and the air pressure in the two first cavities 42 can remain stable. As a result, no negative pressure is generated in the first cavity 42, and the movement of the two rectangular plates 41 is not restricted.

[0028] The insertion rod 3 is provided with a locking mechanism for locking the insertion rod 3 in the first hollow block 2. The locking mechanism includes an L-shaped plate 31, which is rotatably connected to the insertion rod 3. A mounting post 22 is fixedly connected in the first hollow block 2. A top rod 221 is slidably connected in the mounting post 22. A top plate 223 is fixedly connected to the top of the top rod 221. The top plate 223 intermittently abuts against the L-shaped plate 31, and the L-shaped plate 31 intermittently abuts against the first hollow block 2.

[0029] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 When the insertion rod 3 is inserted into the first hollow block 2, the bottom of the insertion rod 3 will gradually approach the top plate 223, eventually causing the top plate 223 to enter the interior of the insertion rod 3. At this time, the L-shaped plate 31 is in a vertical state, and a positioning ball 314 on the L-shaped plate 31 is in the positioning groove on the insertion rod 3. Under the elastic force of the return spring 313, the positioning ball 314 is tightly pressed in the positioning groove of the insertion rod 3. Then, when the insertion rod 3 and the top plate 223 move relative to each other, the L-shaped plate 31 will first apply pressure to the top plate 223, and then the push rod 221 at the bottom of the top plate 223 will slide into the mounting post 22, and then the second spring 222 will be compressed.

[0030] The locking mechanism also includes a second spring 222, which is placed inside the mounting post 22. The two ends of the second spring 222 abut against the mounting post 22 and the top rod 221, respectively. Two mounting pins 312 are fixedly connected inside the L-shaped plate 31. A return spring 313 is fixedly connected to each of the two mounting pins 312. A positioning ball 314 is fixedly connected to the end of the return spring 313 away from the mounting pin 312. The insertion rod 3 has a positioning groove that alternately cooperates with the two positioning balls 314.

[0031] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 As the insertion rod 3 drives the L-shaped plate 31 to continue moving downward, the second spring 222 is compressed to a greater degree, and the elastic potential energy of the second spring 222 becomes stronger. When the elastic potential energy of the second spring 222 reaches the critical point, the top rod 221 will drive the top plate 223 to overcome the force of the return spring 313 and suddenly pop upward. Then the L-shaped plate 31 will be pushed by the top plate 223 to rotate and unfold outward from the insertion rod 3.

[0032] The locking mechanism also includes a first tooth 311 disposed on the L-shaped plate 31 and a second tooth 321 disposed on the rotating plate 32, wherein the first tooth 311 on the L-shaped plate 31 and the second tooth 321 on the rotating plate 32 mesh with each other.

[0033] Reference Figures 6-9Since the first tooth 311 on the L-shaped plate 31 meshes with the second tooth 321 on the rotating plate 32, the rotating L-shaped plate 31 can drive the rotating plate 32 to rotate and unfold synchronously towards the outside of the insertion rod 3. Since the L-shaped plate 31 and the rotating plate 32 rotate and unfold in opposite directions, the rotating plate 32 also rotates to a horizontal state when the L-shaped plate 31 rotates to a horizontal state. At this time, the L-shaped plate 31 and the rotating plate 32 mutually limit each other to prevent the other from rotating too much. At the instant when the L-shaped plate 31 rotates to a horizontal state, another positioning ball 314 will enter the positioning groove on the insertion rod 3, so that the position of the L-shaped plate 31 no longer changes.

[0034] There are four L-shaped plates 31 and four rotating plates 32. The four L-shaped plates 31 and four rotating plates 32 correspond one-to-one, and the four L-shaped plates 31 and four rotating plates 32 are evenly distributed in a circle at the bottom of the insertion rod 3.

[0035] Reference Figures 6-9 By setting four L-shaped plates 31 and four rotating plates 32, the firmness of the connection between the insertion rod 3 and the first hollow block 2 can be strengthened.

[0036] The second hollow block 4 is provided with a sealing mechanism for sealing the connection hole between the insertion rod 3 and the first hollow block 2. The sealing mechanism includes a receiving box 51 with built-in sealant. The receiving box 51 is fixedly connected to the top of the second hollow block 4. A piston cylinder 5 is fixedly connected to the top of the second hollow block 4. A piston rod 53 is slidably connected inside the piston cylinder 5. A connecting block 531 is fixedly connected to the rectangular plate 41. The piston rod 53 is fixedly connected to the connecting block 531.

[0037] Reference Figure 2 and Figure 4 As the second hollow block 4 moves downward, the space above the second hollow block 4 in the first hollow block 2 gradually increases, and the downward speed of the second hollow block 4 is fast enough to allow external air to enter the first hollow block 2 through the insertion hole at the connection between the insertion rod 3 and the first hollow block 2. The air in the space below the second hollow block 4 in the first hollow block 2 is discharged to the outside of the first hollow block 2 through the first one-way valve 23. As the second hollow block 4 continues to move downward, the two rectangular plates 41 come into contact with each other. As the two rectangular plates 41 approach each other, the rectangular plates 41 will drive the piston rod 53 to be pulled out from the piston cylinder 5 through the connecting block 531. Then the sealant in the housing 51 enters the piston cylinder 5 through the first hose 511, thereby blocking the second cavity 43 by the two rectangular plates 41. At this time, the space below the second hollow block 4 in the first hollow block 2 will be sealed.

[0038] The sealing mechanism also includes a first hose 511 and a second hose 521 fixedly connected to the piston cylinder 5. The end of the first hose 511 away from the piston cylinder 5 is fixedly connected to the receiving box 51. The end of the second hose 521 away from the piston cylinder 5 is fixedly connected to an annular nozzle 52. The first hose 511 is provided with a second one-way valve 512, and the second hose 521 is provided with a third one-way valve 522. The annular nozzle 52 is fixedly connected to the first hollow block 2, and the annular nozzle 52, the insertion rod 3, and the push rod 221 are located on the same axis.

[0039] Reference Figure 2 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 When the rotating plate 32 rotates to a horizontal state, the total vertical height of the insertion rod 3 and the rotating plate 32 decreases. As a result, the second hollow block 4 moves upward a certain distance under the action of the first spring. The upward-moving second hollow block 4 will, in turn, push the insertion rod 3 upward through the rotating plate 32. At this time, the L-shaped plate 31 has rotated to a horizontal state. As a result, the insertion rod 3 is pushed upward by the second hollow block 4 to the position of the L-shaped plate 31 and will be blocked by the L-shaped plate 31. At this time, the insertion rod 3 no longer moves. When the second hollow block 4 moves upward, a negative pressure will be generated in the space below the second hollow block 4 in the first hollow block 2. The elastic force of the first spring is sufficient to bounce the second hollow block 4 up. As the second hollow block 4 moves upward, the two rectangular plates 41 gradually separate.

[0040] Reference Figures 2-4 At the instant the two rectangular plates 41 separate, the negative pressure in the space below the second hollow block 4 within the first hollow block 2 is instantly released. Consequently, the air in the space above the second hollow block 4 within the first hollow block 2 is drawn downwards by the negative pressure generated below the first hollow block 2. Since air can only enter from the connection between the insert rod 3 and the first hollow block 2, and a sealing ring 21 is provided at the connection between the insert rod 3 and the first hollow block 2, the insert rod 3 can be adsorbed onto the first hollow block 2 under the action of negative pressure. Simultaneously, as the two rectangular plates 41 move away from each other, the rectangular plates 41 will drive the piston rod 53 to slide into the piston cylinder 5 via the connecting block 531, thereby drawing the sealed air from the piston cylinder 5. The adhesive will flow from the second hose 521 and then be sprayed from the annular nozzle 52 to the connection between the insert rod 3 and the first hollow block 2, so that the connection between the insert rod 3 and the first hollow block 2 is sealed, and the negative pressure inside the first hollow block 2 can always attract the insert rod 3. With the unfolded L-shaped plate 31 contacting the first hollow block 2, the insert rod 3 can maintain a tight connection with the first hollow block 2, thereby initially positioning the two steel plate bodies 1, making it less likely for the two steel plate bodies 1 to move relative to each other, and ensuring that the screw connection position will not be deviated when the two steel plate bodies 1 are connected by screws, thus making the connection between the two steel plate bodies 1 firm.

[0041] The number of blocking mechanisms is specifically two sets, and the two sets of blocking mechanisms are symmetrically distributed on the top of the second hollow block 4. The two sets of blocking mechanisms are respectively matched with the two insertion rods 3.

[0042] Reference Figure 2 By setting two sets of sealing mechanisms, both insert rods 3 can maintain a stable connection with the first hollow block 2, which facilitates the positioning and connection of the two steel plate bodies 1.

[0043] Working principle: This wind farm uses color steel plates. During use, two steel plate bodies 1 are taken. Two insert rods 3 on one steel plate body 1 are inserted into the corresponding insertion holes on the first hollow block 2 of the other steel plate body 1. Pressure is then applied to the steel plate body 1 inserted into the first hollow block 2, causing the insert rods 3 to continue penetrating deeper into the first hollow block 2. At this time, the rotating plate 32 at the bottom of the insert rod 3 gradually approaches and contacts the top surface of the second hollow block 4. As the insert rod 3 continues to penetrate the second hollow block 4, the insert rod 3, through the rotating plate 32,... The two hollow blocks 4 are subjected to pressure, causing the second hollow block 4 to move downwards against the elastic force of the first spring. Consequently, the two rectangular plates 41 inside the second hollow block 4 move downwards synchronously with the second hollow block 4. At this time, the connecting rod 411 is driven by the rectangular plates 41 to swing in an arc around the connection point with the first hollow block 2, with the swing direction downwards. The two rectangular plates 41 are then pushed closer together by the connecting rod 411. Due to the vent holes, external air can enter the two first cavities 42, thus... The air pressure remains stable, so no negative pressure is generated in the first cavity 42, and the movement of the two rectangular plates 41 is not restricted. As the second hollow block 4 moves downward, the space in the upper part of the first hollow block 2 gradually increases, and the downward speed of the second hollow block 4 is fast enough to allow external air to enter the first hollow block 2 through the insertion hole at the connection between the insertion rod 3 and the first hollow block 2. The air in the space in the lower part of the second hollow block 4 in the first hollow block 2 is discharged to the outside of the first hollow block 2 through the first one-way valve 23. As the second hollow block 4 continues to move downward, the two rectangular plates 41 come into contact with each other. As the two rectangular plates 41 approach each other, the rectangular plates 41 will drive the piston rod 53 to be pulled out from the piston cylinder 5 through the connecting block 531. Then the sealant in the container 51 enters the piston cylinder 5 through the first hose 511, so that the second cavity 43 is blocked by the two rectangular plates 41. At this time, the space in the lower part of the second hollow block 4 in the first hollow block 2 will be sealed.

[0044] When the insert rod 3 is inserted into the first hollow block 2, the bottom of the insert rod 3 gradually approaches the top plate 223, eventually causing the top plate 223 to enter the interior of the insert rod 3. At this time, the L-shaped plate 31 is in a vertical state, and a positioning ball 314 on the L-shaped plate 31 is in the positioning groove on the insert rod 3. Under the elastic force of the return spring 313, the positioning ball 314 is tightly pressed into the positioning groove of the insert rod 3. Then, when the insert rod 3 and the top plate 223 move relative to each other, the L-shaped plate 31 first applies pressure to the top plate 223, and then the push rod 221 at the bottom of the top plate 223 slides into the mounting post 22, thereby compressing the second spring 222. As the insert rod 3 drives the L-shaped plate 31 to continue moving downward, the degree of compression of the second spring 222 increases, and the elastic potential energy of the second spring 222 becomes stronger. When the critical point is reached, the push rod 221 will drive the top plate 223 to suddenly pop upward against the force of the return spring 313. Then, the L-shaped plate 31 will be pushed by the top plate 223 to rotate and unfold outward of the insertion rod 3. Since the first tooth 311 on the L-shaped plate 31 meshes with the second tooth 321 on the rotating plate 32, the rotating L-shaped plate 31 can drive the rotating plate 32 to rotate and unfold outward of the insertion rod 3 in sync. Since the L-shaped plate 31 and the rotating plate 32 rotate and unfold in opposite directions, when the L-shaped plate 31 rotates to the horizontal state, the rotating plate 32 also rotates to the horizontal state. At this time, the L-shaped plate 31 and the rotating plate 32 limit each other to prevent the other from rotating too much. At the instant when the L-shaped plate 31 rotates to the horizontal state, another positioning ball 314 will enter the positioning groove on the insertion rod 3, so that the position of the L-shaped plate 31 no longer changes.

[0045] When the rotating plate 32 rotates to a horizontal position, the total vertical height of the insert rod 3 and the rotating plate 32 decreases. Consequently, the second hollow block 4 moves upward a certain distance under the action of the first spring. The upward-moving second hollow block 4 then pushes the insert rod 3 upward through the rotating plate 32. At this time, the L-shaped plate 31 has already rotated to a horizontal position. The insert rod 3, pushed upward by the second hollow block 4, will be blocked by the L-shaped plate 31. At this time, the insert rod 3 stops moving. However, when the second hollow block 4 moves upward, the first... A negative pressure is generated in the space below the second hollow block 4 within the first hollow block 2. The elastic force of the first spring is sufficient to bounce the second hollow block 4 upward. As the second hollow block 4 moves upward, the two rectangular plates 41 gradually separate. At the instant the two rectangular plates 41 separate, the negative pressure in the space below the second hollow block 4 within the first hollow block 2 is instantly released. Consequently, the air in the space above the second hollow block 4 within the first hollow block 2 is drawn downward by the negative pressure generated below the first hollow block 2. Since air can only flow from the insertion rod 3 and the first... A sealing ring 21 is provided at the connection point of the hollow block 2 and the connection point of the insertion rod 3 and the first hollow block 2. Under negative pressure, the insertion rod 3 can be attracted to the first hollow block 2. At the same time, when the two rectangular plates 41 move away from each other, the rectangular plates 41 will drive the piston rod 53 to slide into the piston cylinder 5 through the connecting block 531. Then, the sealant extracted from the piston cylinder 5 will flow from the second hose 521 and then be sprayed from the annular nozzle 52 to the connection point of the insertion rod 3 and the first hollow block 2, so that the connection point of the insertion rod 3 and the first hollow block 2 is sealed. This ensures that the negative pressure in the first hollow block 2 can always attract the insertion rod 3. With the unfolded L-shaped plate 31 contacting the first hollow block 2, the insertion rod 3 can maintain a tight connection with the first hollow block 2. Thus, the two steel plate bodies 1 are initially positioned, making it difficult for the two steel plate bodies 1 to move relative to each other. This ensures that the position of the screw connection will not be deviated when the two steel plate bodies 1 are connected by screws, thus making the connection between the two steel plate bodies 1 firm.

[0046] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
