Detailed Implementation

[0027] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-8 As shown, the embodiment provides a prefabricated assembled power inverter box foundation, including two connecting blocks. The connecting blocks include a support plate 1, an outer support frame 2, and an inner support frame 3. A connecting groove is opened on one side of the support plate 1. The inner support frame 3 is fixed in the connecting groove, and the outer support frame 2 is fixed on the outside of the connecting groove. A connecting cylinder 41 is connected inside one of the inner support frames 3. A first connecting member is provided inside the connecting cylinder 41. A second connecting member 33 is provided on the other inner support frame 3. The second connecting member 33 is inserted and engaged with the connecting cylinder 41.

[0029] The connecting plate is made of cast concrete and reinforced with steel bars. Before construction, connecting blocks of different sizes are prefabricated according to site requirements. Then, two connecting blocks are spliced ​​together. When the connecting blocks are spliced ​​together, the inner support frame 3 and the outer support frame 2 support the support plate 1 from the inside and outside, respectively, making the connecting block more stable as a whole. During connection, the second connecting piece 33 on one side of the inner support frame 3 is inserted into the connecting cylinder 41 inside the other side of the inner support frame 3. At the same time as the second connecting piece 33 is inserted, the first connecting piece clamps the second connecting piece 33 to prevent accidental opening after the two connecting blocks are connected.

[0030] Prestress is applied between the two connecting blocks via prestressed strands, and after being locked together by dedicated permanent anchor rings at both ends of the steel strands, they become a single unit. This allows the two connecting blocks to be tightly connected as one, preventing accidental separation during subsequent use, improving the tightness of the connection between the two connecting blocks, and enhancing the reliability of the device.

[0031] Furthermore, the inner support frame 3 includes longitudinal beams 32 and transverse beams 31. Two or more transverse beams 31 are connected to one side of the longitudinal beams 32, and connecting cylinders 41 are opened on the transverse beams 31 or second connecting members 33 are set on the transverse beams 31. The transverse beams provide lateral support for the frame, while the longitudinal beams 32 provide longitudinal support for the support plate 1, making the support plate 1 more robust during connection and daily use.

[0032] Furthermore, it also includes a reinforcing beam 35 and a foundation sleeve 36. The reinforcing beam 35 is fixed to the bottom of the support plate 1 and connects the inner support frame 3 and the outer support frame 2. This is to make the support plate 1 more solid and stable, preventing structural damage during subsequent installation and support. It also strengthens the overall load-bearing capacity of the foundation, making it more stable and reliable when the power inverter box is installed, preventing accidental collapse during use.

[0033] Furthermore, a foundation sleeve 36 is provided at the connection between the reinforcing beam 35 and the inner support frame 3. The foundation sleeve 36 provides support for the installation of the device, allowing the foundation sleeve 36 to be installed on the wall or other platform, and can form a gap between the support plate 1 and the mounting wall to avoid the installation being too close to the wall.

[0034] Furthermore, the outer support frame 2 is provided with prestressing tension holes 21, and the outer support frame 2 is embedded with drainage pipes 22.

[0035] Furthermore, the longitudinal beam 32 has two or more embedded parts 34, and the embedded parts 34 correspond one-to-one with the transverse beam 31.

[0036] Furthermore, the first connecting member includes a stop, a clamping member, a locking member, and a transmission member; the stop is connected to the bottom of the connecting cylinder 41, the transmission member includes two or more pull rods 42, the inside of the crossbeam 31 is hollow, the end of the stop extends through the connecting cylinder 41 into the inside of the crossbeam 31, the pull rods 42 are slidably connected to the inside of the crossbeam 31, and the pull rods 42 are connected to the stop; the clamping member includes a first push block 43 and a rubber block 44, an opening is provided on the side wall of the connecting cylinder 41, the rubber block 44 is embedded in the opening, the first push block 43 is fixed to the bottom of the pull rod 42, the first push block 43 is provided with a first inclined surface, and the rubber block 44 is provided with a second inclined surface.

[0037] When the two connecting blocks are connected, the second connecting piece 33 on one connecting block is inserted into the connecting cylinder 41 of the other connecting block. The second connecting piece 33 first abuts against the abutment, which compresses backward. The moving abutment simultaneously drives the first push block 43 to move backward via the pull rod 42. The backward-moving first push block 43 abuts against the rubber block 44, and the first inclined surface of the first push block 43 abuts against the second inclined surface of the rubber block 44, pressing the rubber block 44 towards the connecting cylinder 41, thereby clamping the second connecting piece 33 inserted into the connecting cylinder 41. However, when the second connecting piece 33 is inserted to the deepest point in the connecting cylinder 41, the rubber block 44 is also compressed to its tightest state, thus clamping the second connecting piece 33 and preventing it from accidentally falling off during the connection process.

[0038] Further, the locking component includes a first connecting frame 45, a second connecting frame 48, a locking rod 47, and a sleeve 46; both the first connecting frame 45 and the second connecting frame 48 are disposed within the crossbeam 31, and the second connecting frame 48 is sleeved outside the first connecting frame 45; the second connecting block is connected to the pull rod 42; the first connecting frame 45 is sleeved outside the connecting cylinder 41; two or more sleeves 46 are slidably connected to the first connecting block, and the sleeves 46 and the first connecting frame 45 are connected by a first spring; the locking rod 47 is inserted into the sleeve 46, and the locking rod 47 and the sleeve 46 are connected by a second spring; the connecting cylinder 41 The side wall of the first connecting member has clamping holes, which correspond one-to-one with the locking rod 47. The second connecting frame 48 is fixed with a second push block, which corresponds one-to-one with the locking rod 47. The second push block includes a pressing part 491 and a lateral moving part 492. The lateral moving part 492 is connected to one side of the pressing part 491. The bottom of the pressing part 491 is provided with a third inclined surface. The lateral moving part 492 is provided with a push piece 493, which is inclined. The second connecting member 33 includes a connecting post, which is provided with a locking groove 411, which corresponds one-to-one with the locking rod 47. The position of the clamping hole corresponds to the locking groove 411.

[0039] During the process of the connecting post being inserted into the connecting cylinder 41 and pushing and compressing the abutment, the abutment also pulls the second connecting frame 48 backward via the pull rod 42. The second connecting frame 48 moves backward along with the second push block. During the backward movement of the second push block, the push plate 493 of the transverse part 492 first pushes the locking rod 47. The locking rod 47 slides horizontally on the first connecting frame 45 together with the sleeve 46. When the push plate 493 pushes the locking rod 47 to the far end on the other side, the pressing part 491 presses the locking rod 47 downward. When the locking rod 47 is pressed downward by the pressing part 491, it moves towards the connecting cylinder 41 within the sleeve 46. In this application, by setting the locking rod 47 so that when the connecting post is inserted to the deepest point, that is, when the abutment is pressed to the deepest point, the locking rod 47 is just driven to pass through the clamping hole and insert into the locking groove 411 of the connecting post, thereby locking the connecting post and preventing the connecting post from accidentally falling off during subsequent use, which would cause the two connecting blocks to fall off. At the same time, when the locking rod 47 is inserted into the locking groove 411, all parts of the first connector are in a locked state, maintaining the clamping and tightening of the connecting column.

[0040] Furthermore, the locking component also includes a retaining ring 57, which is rotatably connected to the crossbeam 31. A baffle 58 is provided on the retaining ring 57. The retaining ring 57 is connected to the crossbeam 31 via a torsion spring. The abutment component includes a abutment plate 51, a third spring 52, a abutment rod 56, an abutment cylinder 54, and a fourth spring 55. The abutment plate 51 is connected to the inner bottom of the connecting cylinder 41 via the third spring 52. A groove is provided on the side wall of the connecting cylinder 41. The abutment cylinder 54 is connected to the rear side of the abutment plate 51. The abutment rod 56 is connected to the bottom of the abutment cylinder 54 via the fourth spring 55, and extends to the outside of the connecting cylinder 41 through the groove. A fourth inclined surface is provided at the end of the abutment rod 56, which engages with the baffle 58. The end of the abutment plate 51 is connected to the pull rod 42 via a connecting rod. When the connecting rod pushes the abutment plate 51 to its lowest position, the abutment rod 56 on the abutment plate 51 is pushed past the baffle 58. The abutment rod 56 is provided with a fourth inclined surface. Therefore, when it passes the baffle plate 58, guided by the fourth inclined surface, the abutment rod 56 compresses the fourth spring 55 and retracts into the abutment cylinder 54, and then passes through the retaining ring 57 and is locked by the baffle plate 58. Even without the support of the connecting column, the locked abutment plate 51 can still maintain the tension of each clamping component through the pull rod 42, thereby keeping the connecting column in a clamped state. This prevents the connecting column from separating during use, which could lead to foundation cracking and improve the practical reliability of the foundation.

[0041] Furthermore, three crossbeams 31 are configured, and crossbeams 31 are connected to both ends and the middle of the longitudinal beam 32. The interior of the crossbeams 31 is connected to the longitudinal beam 32, and a release mechanism is also included. The release mechanism includes a button 61, a main drive rod 62, a secondary drive rod 63, and a third push block 65. The main drive rod 62 is slidably connected inside the longitudinal beam 32, and the main drive rod 62 is connected to the end of the inner wall of the longitudinal beam 32 by a fifth spring 66. A secondary drive rod 63 is slidably connected inside each crossbeam 31, and three third push blocks 65 are fixed to the main drive rod 63. On the moving rod 62, the third push block 65 is provided with a fifth inclined surface. The secondary drive rod 63 corresponds one-to-one with the third push block 65. The secondary drive rod 63 abuts against the main drive rod 62, and the third push block 65 is located on one side of the corresponding secondary drive rod 63. The retaining ring 57 is fixed with a fourth push block 67, which is provided with a sixth inclined surface. The secondary drive rod 63 abuts against the fourth push block 67. The main drive rod 62 is fixed with a fifth push block 64, which is provided with a seventh inclined surface. The button 61 abuts against the seventh inclined surface.

[0042] When it is necessary to separate the two connecting blocks, first press button 61. Button 61 pushes the fifth push block 64, which, under the action of the seventh inclined surface, drives the main drive rod 62 upward. At the same time, the third push block 65 pushes the secondary drive rod 63 towards the connecting cylinder 41. The secondary drive rod 63 pushes the fourth push block 67 located on the retaining ring 57. Due to the sixth inclined surface on the fourth push block, the retaining ring 57 gains rotational deflection power, and the retaining ring 57 rotates accordingly. At this time, the baffle 58 on the retaining ring 57 that holds the abutment rod 56 also rotates, and the abutment rod 56 loses its support. Thus, by releasing each of the first connecting parts, the connecting post can be removed from the connecting cylinder 41, achieving release. This setting allows for the simultaneous release of each connecting post, providing a convenient release function.

[0043] Other techniques in this embodiment are based on existing technologies.
