DETAILED DESCRIPTION

[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the relevant technical solutions. Obviously, the embodiments described are only some embodiments, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1 As shown, the prefabricated cabin-type substation cabin structure disclosed in this embodiment, which is easy to assemble, includes a floor 1 , a first side wall 2 , a second side wall 3 and a top plate 4 .

[0024] Two first side walls 2 and two second side walls 3 are arranged between the floor 1 and the top plate 4. The two first side walls 2 are symmetrically arranged between the floor 1 and the top plate 4. The two second side walls 3 are respectively arranged at the two ends of the first side wall 2, and the two ends of each second side wall 3 are respectively connected to the ends of the two first side walls 2 at the same time.

[0025] The floor 1 includes a main floor panel 11, which is surrounded by positioning steps 15. A first fixing member for securing the first side wall 2 to the positioning steps 15 is provided on the side wall of the main floor panel 11 near the first side wall 2. The first fixing member is removably mounted on the side wall of the main floor panel 11. A second fixing member for securing the second side wall 3 to the positioning steps 15 is provided on the side wall of the main floor panel 11 near the second side wall 3. The second fixing member is also removably mounted on the side wall of the main floor panel 11. Several positioning posts 16 are evenly spaced in the area of ​​the positioning steps 15 where the second side wall 3 is mounted.

[0026] The first side wall 2 includes a first frame 21, and connecting side panels 22 are provided on both sides of the first frame 21. A plurality of connecting holes 221 are evenly distributed along the height direction on the opposite sides of the two connecting side panels 22. Reinforcing ribs 23 are provided at the upper and lower ends of the first frame 21 near the connecting side panels 22. The connecting side panels 22 and the reinforcing ribs 23 cooperate to form a slot for matching the second side wall 3.

[0027] The second side wall 3 includes a second frame 31, and trapezoidal connecting blocks 32 are provided on both sides of the second frame 31. A plurality of trapezoidal connecting blocks 32 are evenly distributed on the second frame 31 along the height direction. The trapezoidal connecting blocks 32 are slidably installed in the second frame 31 and are connected to the interior of the second frame 31 through a return spring.

[0028] A plurality of detachable wall panel modules 5 are mounted on both the first frame 21 and the second frame 31 .

[0029] like Figure 2 As shown, the first fixing member includes a first fixing column 12, which is inserted into the side wall of the main floor 11 through a first guide column 121, and the first fixing column 12 is also provided with a locking bolt 14 for fixing the first fixing column 12 to the main floor 11.

[0030] During use, when the bottom of the first side wall 2 is locked in the positioning step 15 and the first side wall 2 and the second side wall 3 are connected to each other, it is only necessary to tighten the locking bolt 14 and fix the first fixing column 12 to the side wall of the main floor 11, so that the bottom of the first side wall 2 is locked in the positioning step 15 through the first fixing column 12, and the installation of each wall panel module is completed.

[0031] like Figure 2 As shown, the second fixing member includes a second fixing column 13 , which is plugged into the side wall of the main floor 11 through a second guide column 131 , and a locking bolt 14 is also provided on the second fixing column 13 .

[0032] During use, after the second side wall 3 is inserted into the positioning step 15 and each positioning column 16 is inserted into the bottom of the second side wall 3, it is only necessary to tighten the locking bolt 14 and fix the second fixing column 13 to the side wall of the main floor 11 to complete the installation of the second side wall 3.

[0033] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, the wall panel module 5 includes a plurality of mounting rods 51, which are fixedly installed in the second frame 31 or the first frame 21. The mounting rods 51 are C-shaped, and a plurality of interconnected wall panels 52 are equidistantly arranged on the mounting rods 51. The wall panels 52 are provided with positioning plugs 55 for being inserted into the open ends of the mounting rods 51. A plurality of countersunk holes 521 are provided on each wall panel 52 along the installation direction of the mounting rods 51, and a connecting unit 6 for fixing the wall panel 52 to the mounting rods 51 is installed in the countersunk holes 521.

[0034] The mounting rod 51 can be made of a square steel tube with a slot cut into one side. During use, simply insert the positioning inserts 55 on each wall panel 52 into the open end of the mounting rod 51. The wall panel 52 is then locked into the mounting rod 51 using the connecting unit 6. By combining multiple wall panels 52, a complete wall surface is formed.

[0035] like Figure 5-Figure 7 As shown, the connecting unit 6 includes a hollow plug rod 61 which is detachably installed in the countersunk hole 521, and an adjusting inner rod 62 is installed in the hollow plug rod 61 along its axial sliding direction, and the adjusting inner rod 62 and the interior of the hollow plug rod 61 are connected to each other through a second spring 63. Two clamping rods 64 are symmetrically provided at one end of the hollow plug rod 61, and a mounting groove for installing the clamping rod 64 is provided on the side wall of the hollow plug rod 61. One end of the clamping rod 64 is hinged in the mounting groove, and a ball head rod 65 is also provided at the hinged end of the clamping rod 64. An annular groove 621 matching the ball head rod 65 is provided on the adjusting inner rod 62, and a threaded section 66 is provided at the end of the hollow plug rod 61 away from the clamping rod 64, and a locking nut 67 is installed on the threaded section 66.

[0036] In the initial state, due to the elastic force of the second spring 63, both latching rods 64 are in an outwardly open position. During use, after the positioning plug 55 is inserted into the open end of the mounting rod 51, the hollow latching rod 61 is inserted into the countersunk hole 521, and the latching rod 64 is fully inserted into the mounting rod 51. During this process, the latching rod 64 is pressed and rotated into the mounting groove. When the latching rod 64 is fully inserted into the mounting rod 51, it is opened again due to the elastic force of the second spring 63. The locking nut 67 can then be screwed. Through the cooperation of the locking nut 67 and the threaded section 66, the hollow latching rod 61 can be pulled away from the mounting rod 51, so that the latching rod 64 is finally stuck on both sides of the open end of the mounting rod 51, and the wall panel 52 can be fixed to the mounting rod 51.

[0037] When disassembly and replacement are required, it is only necessary to slightly loosen the locking nut 67 and then press the adjusting inner rod 62 toward the side close to the mounting rod 51. Through the cooperation between the annular groove 621 and the ball head rod 65, the adjusting inner rod 62 can drive the clamping rod 64 to rotate, so that the clamping rod 64 is retracted into the mounting groove. At this time, the hollow insert rod 61 can be taken out as a whole, thereby quickly releasing the fixation of the wall panel 52.

[0038] like Figure 5 and Figure 6 As shown, the wall panel module 5 also includes an auxiliary inner rod 53 installed inside the installation rod 51, the open end of the auxiliary inner rod 53 is in the same direction as the open end of the installation rod 51, and the auxiliary inner rod 53 is connected to the inside of the installation rod 51 through a plurality of first springs 54.

[0039] In this state, the relevant components in the connecting unit 6 will be clamped on both sides of the open end of the auxiliary inner rod 53. Through the cooperation of the auxiliary inner rod 53 and the first spring 54, a certain buffer can be provided for the wall panel 52, thereby improving the impact resistance of the wall.

[0040] like Figure 6 and Figure 7 As shown, a plurality of auxiliary rods 671 are arranged in a circle on the side wall of the locking nut 67. During use, the operator can use a tool or hold the auxiliary rods 671 to screw the locking nut 67, thereby improving the installation convenience of the device and ensuring that the locking nut 67 is fully tightened to ensure the fixing effect of the connecting unit 6.

[0041] How it works when used:

[0042] 1. First, install the corresponding wall panel modules 5 on the first frame 21 and the second frame 31. The wall panel modules 5 cooperate with the first frame 21 or the second frame 31 to form a complete wall. Specifically, simply insert the positioning block 55 on each wall panel 52 into the open end of the mounting rod 51, insert the hollow insertion rod 61 into the countersunk hole 521, and fully insert the locking rod 64 into the mounting rod 51. During this process, the locking rod 64 is pressed and rotated into the mounting slot. Once the locking rod 64 is fully inserted into the mounting rod 51, it is opened again by the elastic force of the second spring 63. Then, tighten the locking nut 67. The locking nut 67 cooperates with the threaded section 66 to pull the hollow insertion rod 61 away from the mounting rod 51, so that the locking rod 64 finally engages on both sides of the open end of the mounting rod 51, thus securing the wall panel 52 to the mounting rod 51. By combining multiple wall panels 52, a complete wall surface is formed.

[0043] 2. Then, place the two second frames 31 on the positioning steps 15 on either side of the main floor 11 (the two second side walls 3 are symmetrically located on both sides of the main floor 11), and insert the positioning posts 16 into the positioning holes at the bottom of the second frames 31. Then, use the second fixings to secure the second side walls 3 to the positioning steps 15, completing the installation of the second side walls 3.

[0044] 3. Then, push the first side wall 2 into the positioning step 15 from the side in a direction parallel to the second side wall 3. During this process, the trapezoidal connecting blocks 32 are respectively inserted into the connecting holes 221, and the edges of the second frame 31 are inserted into the slots formed by the connecting side panels 22 and the reinforcing ribs 23, thereby connecting the first side wall 2 and the second side wall 3. The two first side walls 2 and the two second side walls 3 form a complete wall.

[0045] 4. Finally, install the top plate 4 on the top of the wall, and connect the top plate 4 to the reinforcing ribs 23 at the top by fastening bolts and other components, thereby completing the overall assembly work.

[0046] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although detailed descriptions have been provided with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
