Description

Technical Field

[0001] This invention relates to the field of prefabricated substation technology, specifically to a modular prefabricated substation and its installation method. Background Technology

[0002] A prefabricated substation refers to a power building constructed by assembling electrical equipment such as transformers, high-voltage switchgear, and secondary protection equipment included in an integrated substation using prefabricated cabin structures. The prefabricated cabins are first produced in a factory by producing multiple cabin modules. These modules are then transported to the construction site, where they are combined to form a prefabricated cabin. Finally, various electrical equipment is installed into the prefabricated cabin, thus assembling the prefabricated substation.

[0003] In existing technologies, after installing multiple electrical devices into the prefabricated cabin, the electrically connected power cables on the devices need to be moved outward to connect the devices with other power cables and achieve the purpose of power conversion. However, the interior space of the prefabricated cabin in existing technologies is generally small. After installing multiple electrical devices into the prefabricated cabin, it is not convenient to move and adjust the placement area of ​​the electrically connected power cables, and it is easy to cause a large number of power cables to accumulate. Summary of the Invention

[0004] This invention proposes a modular prefabricated substation and its installation method, which solves the problem in the prior art that it is inconvenient for the power cables electrically connected to the power equipment to pass through the prefabricated compartment after the prefabricated substation is assembled.

[0005] The technical solution of the present invention is as follows: A modular prefabricated substation includes prefabricated modules, wherein the number of prefabricated modules is set to multiple, the multiple prefabricated modules are divided into two groups, and the multiple prefabricated modules located in the same group are fixedly connected together, and further includes:

[0006] The mounting base is fixedly connected to the inner bottom wall of the prefabricated cabin;

[0007] A U-shaped slot frame is fixedly connected to the prefabricated cabin. The number of U-shaped slot frames is the same as the number of mounting bases. Multiple cable entry slots are opened on both sides of the U-shaped slot frame, and a flip-close assembly is provided in the cable entry slot.

[0008] The mounting box is connected to one side of the prefabricated cabin. Both sides of the U-shaped trough are provided with traction ropes. A traction winding assembly is provided between the mounting box and the multiple traction ropes. One end of each traction rope is provided with a connecting clamp assembly for connecting to a power cable. The connecting clamp assembly is slidably disposed in the U-shaped trough.

[0009] To keep the unused cable inlet slot closed, the flip-close assembly further includes a closing plate and a rotating component. The closing plate is located inside the cable inlet slot, and the rotating component is fixedly connected inside the U-shaped slot frame. A rotating shaft is rotatably connected to the rotating component, and a connecting piece is fixedly connected between the rotating shaft and the closing plate. A spring is provided between the rotating shaft and the rotating component.

[0010] To facilitate the entry of power cables into the U-shaped trough, a sloping groove is provided on the sealing plate, based on the aforementioned scheme.

[0011] To further wind up the traction rope, the traction winding assembly includes a mounting shaft and a winding drum. Two mounting shafts are fixedly connected to both sides of the interior of the mounting box. Multiple winding drums are rotatably sleeved on the mounting shafts. Each winding drum corresponds to a traction rope, and the traction rope is wound onto the winding drum.

[0012] To facilitate the removal of the power cable from the mounting box, multiple lead wire grooves are fixedly connected to both sides of the interior of the mounting box, with each lead wire groove corresponding to a winding drum.

[0013] To connect the traction rope to the power cable connector, the connection clamping assembly further includes a connecting cylinder, a semi-circular clamping groove, a pressing block, and a connecting plate. The connecting cylinder is slidably disposed within the U-shaped groove frame. Two semi-circular clamping grooves are symmetrically fixedly connected to the inner wall of the connecting cylinder. Sliding grooves are provided on both the upper and lower sides of the connecting cylinder, and the pressing block is slidably connected within the sliding groove. The pressing block is in contact with the outer arc surface of the semi-circular clamping groove. A screw pushing structure is provided between the two pressing blocks and the connecting cylinder. The connecting plate is fixedly connected to the connecting cylinder. One end of the traction rope is rotatably connected to the connecting plate via a rotating shaft. Multiple connecting blocks are also fixedly connected to the end of the traction rope near the connecting plate. Multiple metal connecting pieces are fixedly connected to both the upper and lower sides of the connecting blocks.

[0014] In order to improve the connection effect of the semi-circular clamping groove on the power cable, based on the aforementioned scheme, a tension groove is provided on the outer arc surface of the semi-circular clamping groove, and multiple friction protrusions are provided on the inner arc surface of the semi-circular clamping groove.

[0015] In order to adjust the position of the extrusion block in the connecting cylinder, based on the aforementioned scheme, the screw pushing structure includes a connector and an adjusting screw. The connector is slidably disposed in the connecting cylinder, the extrusion block is fixedly connected to the connector, and the adjusting screw is threadedly connected to the connecting cylinder, and the adjusting screw is rotatably connected to the connector.

[0016] The working principle and beneficial effects of this invention are as follows:

[0017] In this invention, after assembling the prefabricated cabin, multiple electrical devices are installed inside the cabin. The power cables connected to these devices are then passed through the nearest inlet slot, allowing them to enter the U-shaped cable tray. A connecting clamp assembly is used to maintain the connection between the traction rope and the power cable. A traction winding assembly winds the traction rope, causing it to pull the connecting clamp assembly within the U-shaped cable tray. During this traction process, the power cable passes through the U-shaped cable tray and enters the mounting box. The power cable is then distributed and transported via a lead-in slot. This invention allows power cables from the electrical devices installed inside the prefabricated cabin to easily exit the cabin, while also preventing the problem of a large number of power cables accumulating together.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, as Figures 1 to 10 As shown, this embodiment proposes a modular prefabricated substation, including a prefabricated cabin 1. The number of prefabricated cabins 1 is set to multiple, and the multiple prefabricated cabins 1 are divided into two groups. The multiple prefabricated cabins 1 in the same group are fixedly connected together. The prefabricated cabin 1 is a common prefabricated structural chamber in the prior art. Multiple cabin modules are assembled and combined to form a complete prefabricated cabin 1. Some larger prefabricated substations are divided into two layers, with a support platform in the middle for support.

[0032] It also includes mounting bases 2. Multiple mounting bases 2 are fixedly connected to the inner bottom wall of the prefabricated cabin 1. The mounting bases 2 are existing technology devices used to determine the installation area of ​​electrical equipment and to determine the installation position of electrical equipment in the prefabricated cabin 1.

[0033] Multiple U-shaped slot frames 3 are fixedly connected inside the prefabricated cabin 1. The number of U-shaped slot frames 3 is the same as the number of mounting bases 2. Multiple cable entry slots are opened on both sides of the U-shaped slot frames 3. A flip-closing assembly is installed in the cable entry slot. The flip-closing assembly includes a closing plate 6 and a rotating component 7. The closing plate 6 is located in the cable entry slot. The rotating component 7 is fixedly connected to the U-shaped slot frame 3. A rotating shaft 8 is rotatably connected to the rotating component 7. A connecting piece 9 is fixedly connected between the rotating shaft 8 and the closing plate 6. A spring 10 is installed between the rotating shaft 8 and the rotating component 7. The closing plate 6 has multiple cable entry slots. With a sloping groove 11, when it is necessary to transport the power cable connected to the power equipment, the closing plate 6 is pushed open, so that the closing plate 6 and the rotating shaft 8 rotate together along the center point of the rotating shaft 8, and the joint of the power cable passes through the inlet groove and extends into the U-shaped trough frame 3. The outer wall of the power cable is in contact with the inner wall of the sloping groove 11, which effectively improves the convenience of moving the power cable in the future. Under the action of the spring 10, the closing plate 6 can ensure the fit between itself and the power cable, which can effectively ensure that the power cable will not move randomly during the movement.

[0034] One side of the prefabricated cabin 1 is connected to the installation box 4. Both sides of the U-shaped trough frame 3 are provided with traction ropes 5. A traction winding assembly is provided between the installation box 4 and the multiple traction ropes 5. The traction winding assembly includes an installation shaft 12 and a winding drum 13. Two installation shafts 12 are fixedly connected to both sides of the installation box 4. Multiple winding drums 13 are rotatably sleeved on the installation shafts 12. The winding drums 13 correspond one-to-one with the traction ropes 5. The traction ropes 5 are wound on the winding drums 13. Multiple lead wire grooves 14 are fixedly connected to both sides of the installation box 4. The lead wire grooves 14 correspond one-to-one with the winding drums 13. By rotating the corresponding winding drums 13, the winding drums 13 wind up the traction ropes 5 and pull the power cable into the installation box 4. According to the subsequent delivery position of the power cable, the power cable is passed through the corresponding lead wire grooves 14 to determine the subsequent delivery position of the power cable.

[0035] One end of the traction rope 5 is equipped with a connecting clamping assembly for connecting to a power cable. The connecting clamping assembly includes a connecting cylinder 15, a semi-circular clamping groove 16, a pressing block 17, and a connecting plate 18. The connecting cylinder 15 is slidably disposed within the U-shaped groove frame 3. Two semi-circular clamping grooves 16 are symmetrically fixedly connected to the inner wall of the connecting cylinder 15. Sliding grooves are provided on both the upper and lower sides of the connecting cylinder 15, and pressing blocks 17 are slidably connected within the sliding grooves. The pressing blocks 17 are in contact with the outer arc surface of the semi-circular clamping grooves 16. A screw pushing structure is provided between the two pressing blocks 17 and the connecting cylinder 15. The device includes a connector 24 and an adjusting screw 25. The connector 24 is slidably disposed inside the connecting cylinder 15. The extrusion block 17 is fixedly connected to the connector 24. The adjusting screw 25 is threadedly connected to the connecting cylinder 15 and is rotatably connected to the connector 24. Because different power cables have different sizes, for larger power cables that are inserted into the connecting cylinder 15, the adjusting screw 25 is rotated to move within the connecting cylinder 15, pushing the connector 24 and the two extrusion blocks 17 to move within the connecting cylinder 15. Then, the two semi-circular clamping grooves 16 are pushed to extrude and clamp the power cable.

[0036] A connecting plate 18 is fixedly connected to the connecting cylinder 15. One end of the traction rope 5 is rotatably connected to the connecting plate 18 through a rotating shaft 19. A tension groove 22 is provided on the outer arc surface of the semi-arc clamping groove 16. Multiple friction protrusions 23 are provided on the inner arc surface of the semi-arc clamping groove 16. The semi-arc clamping groove 16 is squeezed by the moving extrusion block 17, so that the semi-arc clamping groove 16 is bent and deformed at the position of the tension groove 22. The multiple friction protrusions 23 in the semi-arc clamping groove 16 contact the power cable to complete the fastening connection of the power cable.

[0037] Multiple connecting blocks 20 are fixedly connected to one end of the traction rope 5 near the connecting plate 18. Multiple metal connecting pieces 21 are fixedly connected to both the upper and lower sides of the connecting block 20. For some smaller power cables, the power cable can move side by side with the traction rope 5. When the power cable is inserted into the U-shaped trough 3, the deformable metal connecting pieces 21 are used to connect with the power cable. During the movement of the traction rope 5, multiple power cables can be moved synchronously.

[0038] The connecting clamping assembly is slidably disposed within the U-shaped groove frame 3, and also includes a U-shaped slide groove 26. The U-shaped slide groove 26 is fixedly connected to the inner bottom wall and the inner top wall of the U-shaped groove frame 3. A sliding block 27 is slidably connected within the U-shaped slide groove 26. The upper and lower sides of the connecting cylinder 15 are ball-jointed with the sliding block 27 and a rotating ball 28. During the movement of the connecting cylinder 15 driven by the traction rope 5, the connecting cylinder 15 and the two sliding blocks 27 slide between the two U-shaped slide grooves 26.

[0039] The working principle of this modular prefabricated substation:

[0040] First, after assembling the prefabricated cabin 1, multiple electrical devices are installed into the prefabricated cabin 1. The sealing plate 6 is pushed open, so that the sealing plate 6 and the rotating shaft 8 rotate together along the center point of the rotating shaft 8. The joint of the power cable is passed through the inlet groove and inserted into the U-shaped trough frame 3. The outer wall of the power cable is in contact with the inner wall of the sloping groove 11, which effectively improves the convenience of moving the power cable in the future. Under the action of the spring 10, the sealing plate 6 can ensure the fit between itself and the power cable.

[0041] The larger power cable is inserted into the connecting cylinder 15, and the adjusting screw 25 is rotated to move the adjusting screw 25 within the connecting cylinder 15, pushing the connecting piece 24 and the two pressing blocks 17 to move within the connecting cylinder 15. Then, the two semi-arc clamping grooves 16 are pushed to press and clamp the power cable. When the smaller cable is inserted into the U-shaped groove frame 3, a deformable metal connecting piece 21 is used to connect it to the power cable. During the movement of the traction rope 5, multiple power cables can be moved synchronously.

[0042] The winding drum 13 is driven to rotate on the mounting shaft 12, so that the winding drum 13 winds up the traction rope 5 and pulls the power cable into the mounting box 4. Then, according to the subsequent delivery position of the power cable, the power cable is passed through the corresponding lead groove 14 to determine the subsequent delivery position of the power cable.

[0043] Example 2: Based on a modular prefabricated substation, this invention also proposes an installation method for the modular prefabricated substation, specifically including the following steps:

[0044] Step 1, Assembly: After assembling the prefabricated cabin 1, install multiple electrical devices into multiple prefabricated cabins 1;

[0045] Step 2, move the power cable: push open the sealing plate 6, so that the sealing plate 6 and the rotating shaft 8 rotate together along the center point of the rotating shaft 8, and insert the joint of the power cable through the inlet groove into the U-shaped trough frame 3;

[0046] Step 3: Connect the power cable: Insert the larger power cable into the connecting cylinder 15, rotate the adjusting screw 25 to move the adjusting screw 25 within the connecting cylinder 15, push the connecting piece 24 and the two pressing blocks 17 within the connecting cylinder 15, and then push the two semi-arc clamping grooves 16 to press and clamp the power cable. When the smaller cable is inserted into the U-shaped groove frame 3, use the deformable metal connecting piece 21 to connect it to the power cable.

[0047] Step 4: Transporting the power cable: Drive the winding drum 13 to rotate on the mounting shaft 12, so that the winding drum 13 winds up the traction rope 5 and pulls the power cable into the mounting box 4. According to the subsequent transport position of the power cable, pass the power cable through the corresponding lead groove 14 to determine the subsequent transport position of the power cable, so that the power cable can be electrically connected to other power equipment.

[0048] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
