Description

Technical Field

[0001] The utility model relates to the technical field of box-type substations, in particular to a pre-installed box-type substation. Background Art

[0002] Box-type substation, also known as prefabricated substation or prefabricated transformer substation. It is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It organically combines the functions of transformer step-down and low-voltage distribution, and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box. It is particularly suitable for urban network construction and transformation. It is a new type of substation that has emerged after civil substations. Box-type substations are suitable for mines, factories and enterprises, oil and gas fields and wind power stations. It replaces the original civil distribution rooms and distribution stations and becomes a new type of complete set of power transformation and distribution equipment.

[0003] After searching, the prior art has an authorization announcement number of CN209544916U, which discloses a prefabricated box-type substation, including a box-type substation and a controller. The low-voltage room, transformer room, and high-voltage room of the box-type substation are independently provided with box doors and lighting lamps. The front end of the left wall of the box door is provided with a pressure piece. The front end surface of each of the low-voltage room, transformer room, and high-voltage room is provided with a rectangular groove corresponding to the pressure piece. The rectangular grooves are provided with upper and lower symmetrical conductive pieces. The rotating shaft of the conductive piece is deflected by the pressure piece squeezing the cylindrical body of the conductive piece. When the door is opened, relative to the removal of the external force, the conductive pieces are tightly attached together, thereby connecting the circuit of the lighting lamp and lighting the lamp. A plurality of non-powered hoods are fixedly connected to the top of the box-type substation. The utility model has an integrated operation of door opening and lighting, which is convenient for maintenance personnel to repair the box-type substation when the brightness is insufficient.

[0004] The above patent still has some problems when in use. For example, when in use, the box-type substation needs to be transported to the place of use. The box-type substation is large in size and weight. When the installation location cannot use large equipment such as cranes, the installation cannot continue. It can only be done by manually lifting one end and then using a forklift to transport the substation box down. Such operation requires a lot of manpower and material resources, and may cause the staff to be crushed by the substation box. Therefore, we need to propose a pre-installed box-type substation. Utility Model Content

[0005] The purpose of the utility model is to provide a prefabricated box-type substation, which is achieved by bolting a bolting plate to the top of a transfer plate, and then lifting the assembly to pull the substation box. When the rear end of the substation box contacts the installation block, the cable gives the front end of the substation box a backward and upward force, thereby lifting the front end of the substation box, and then inserting the fork of a forklift into the front end of the substation box, and then removing the bolting plate to transport the substation box down, so as to solve the problems raised in the above-mentioned background technology.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the 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.

[0024] The utility model provides: a pre-installed box-type substation, such as Figure 1-4 As shown, it includes a substation box 1, two sets of mounting blocks 4 are symmetrically bolted to one side of the substation box 1, and support frames 3 are rotatably mounted on the outer sides of the two sets of mounting blocks 4. Bolting plates 7 are fixedly provided at the bottom ends of the two sets of support frames 3, and lifting components for lifting the outer ends of the substation box 1 are provided on the sides of the two sets of support frames 3;

[0025] The lifting assembly includes a first connecting wheel 8, a second connecting wheel 9 and a driving module. The first connecting wheel 8 and the second connecting wheel 9 are each provided with two groups. The two groups of first connecting wheels 8 and second connecting wheels 9 are symmetrically installed on both sides of the substation box 1. The first connecting wheel 8 and the second connecting wheel 9 are both close to the front end of the substation box 1. By bolting the bolting plate 7 above the transfer plate, the lifting assembly pulls the substation box 1. When the rear end of the substation box 1 contacts the mounting block 4, the cable 2 gives the front end of the substation box 1 a backward and upward force, thereby lifting the front end of the substation box 1. Then, the forklift's fork is inserted into the front end of the substation box 1, and the bolting plate 7 is removed to transport the substation box 1 down, thereby reducing manpower and material resources while preventing the staff from being crushed by the substation box. When the substation box 1 is installed and no longer moves, the lifting assembly is removed from the side of the substation box 1, and then installed on the side of the new substation box 1 for reuse, so that the lifting assembly can be reused, thereby reducing the production cost of the substation.

[0026] Preferably, the driving module includes a cable 2, a servo motor 5, a winding drum 6, a first rotating wheel 10, a second rotating wheel 11 and a mounting column 13. The servo motor 5 is bolted to the inside of the mounting block 4. The winding drum 6 is keyed to the output end of the servo motor 5, and the first rotating wheel 10 and the second rotating wheel 11 are both rotatably arranged inside the corresponding support frame 3, and the mounting column 13 is fixedly installed inside the corresponding support frame 3. The servo motor 5 is fixedly connected to the substation box 1 through the mounting block 4. The servo motor 5 is started to drive the winding drum 6 to rotate, and the cable 2 is wound around the winding drum 6. The winding drum 6 rotates forward and reverse to release or retract the cable 2.

[0027] Furthermore, one end of the cable 2 is rotatably sleeved on the outer arc surface of the mounting column 13, and the other end of the cable 2 slides through the first connecting wheel 8, the second rotating wheel 11, the second connecting wheel 9, the first rotating wheel 10 and the winding drum 6 in sequence, and the first connecting wheel 8 and the second connecting wheel 9 are both rotatably connected to the substation box body 1, and one end of the cable 2 is sleeved on the outer arc surface of the sleeve wheel 12. When the other end of the cable 2 is wound by the winding drum 6, the cable 2 gradually becomes shorter, thereby giving the front end of the substation box body 1 a backward and upward force through the first connecting wheel 8 and the second connecting wheel 9, thereby lifting the front end of the substation box body 1.

[0028] Furthermore, a mounting hole 14 corresponding to the socket wheel 12 is provided on the side of the support frame 3, and a plug-in rod 16 is passed through the internal thread of the socket wheel 12, and a plug-in hole 17 corresponding to the plug-in rod 16 is provided on the side of the support frame 3. By inserting the socket wheel 12 into the mounting hole 14, and then turning the plug-in rod 16 into the plug-in hole 17, and passing the plug-in rod 16 through the socket wheel 12 to limit the socket wheel 12, the socket wheel 12 is prevented from falling off from the side of the support frame 3, thereby ensuring the stability of the cable 2 during operation, and when the cable 2 needs to be removed, the socket wheel 12 can be pulled out.

[0029] It is worth noting that the two sets of support frames 3 are fixedly installed with a tightening block 15 on one side close to the substation box 1, and the two sets of tightening blocks 15 are in contact with the substation box 1. When the lifting component is started, the substation box 1 will be driven to move backward and upward. The substation box 1 is blocked by setting the tightening block 15 to prevent the substation box 1 from moving backward, and at the same time, the substation box 1 and the support frame 3 are prevented from being too close to each other, causing the cable 2 to be entangled.

[0030] Specifically, the corresponding surfaces of the two groups of support frames 3 are fixedly installed with mounting columns 13, and the mounting blocks 4 are rotatably connected to the support frames 3 through the mounting columns 13. The mounting columns 13 are provided to rotatably connect the support frames 3 and the mounting blocks 4. When the lifting assembly drives the front end of the substation box 1 to lift, the mounting blocks 4 will move with the substation box 1, because the support frames 3 and the mounting blocks 4 are rotatably connected, thereby preventing the support frames 3 from moving with the mounting blocks 4.

[0031] In addition, sliding grooves corresponding to the cable 2 are provided inside the first connecting wheel 8, the second connecting wheel 9, the first rotating wheel 10 and the second rotating wheel 11, and the cable 2 contacts the upper surfaces of the sliding grooves of the first rotating wheel 10 and the second rotating wheel 11 respectively. After the cable 2 extends from the inside of the winding drum 6, it first passes through the upper surface of the first rotating wheel 10, then slides around the second connecting wheel 9, and extends from the bottom of the second connecting wheel 9 and contacts the upper surface of the second rotating wheel 11, and then contacts the first connecting wheel 8 through the lower surface of the second rotating wheel 11. After the cable 2 slides around the first connecting wheel 8, it extends from the bottom of the first connecting wheel 8 and is connected to the socket wheel 12, thereby achieving the goal of lifting the front end of the substation box 1 while increasing the stability of the movement of the cable 2.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
