Description

Technical Field

[0001] The present invention relates to the technical field of box-type substations, and particularly to a grid box-type substation with an energy storage effect. Background Art

[0002] An energy storage substation is a power facility integrating energy storage, conversion, and regulation functions. Its main function is to store energy in an energy storage device for feedback and supplementation when needed by the power system to achieve the balanced and stable operation of the power system. The main components of an energy storage substation include: energy storage equipment, inverters, intelligent control systems, and substations, etc.

[0003] In an energy storage substation, the energy storage device is usually a battery pack for storing electric energy, such as lithium-ion batteries, sodium-sulfur batteries, supercapacitors, etc. During charging, current is input from an external power system for charging to store external energy in the energy storage device; when power supply is required for a load, the energy storage device can release this part of electric energy through an electric control system; Inverter for energy conversion: An inverter is usually a device for converting direct current into alternating current. In an energy storage substation, the inverter is mainly used to convert the direct current stored in the energy storage device into alternating current to supply the electric energy required by the power grid or load; Intelligent control system for managing energy flow: The intelligent control system of an energy storage substation can monitor the operating state of the power system and the charge and discharge states of the energy storage device, and adjust the quantity of electric energy input or output in real time to ensure the stability and reliability of the power system operation. For example, when voltage or current fluctuations occur in the power system, the intelligent control system can adjust the charge and discharge amount of the energy storage to balance the supply and demand of electric energy and ensure power quality and stability; Substation connecting to the power grid: The energy storage substation outputs the alternating current converted by the inverter to the power grid or load through the substation. At the same time, the substation also transmits the alternating current of the power grid to the inverter for charging or current feedback operations. In this way, the energy storage substation can support and stabilize the power system, which is of great significance for improving power quality and efficiency and reducing energy waste.

[0004] The energy storage substation needs to cooperate with a battery pack for energy storage. However, this method requires additional installation of battery equipment in an outdoor substation, and the battery itself has the risk of explosion and combustion in the outdoor environment, which is highly dangerous when installed together with the substation. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a grid box-type substation with an energy storage effect to solve the problems raised in the above background technology. The structure of the present invention is novel. Under the action of the driving component, when the temperature inside the energy storage box is relatively high, it is pushed away from the box-type substation body. During this process, the opening of the heat dissipation window becomes larger, improving the air flow and heat dissipation ability, reducing the temperature inside the energy storage box and at the same time avoiding the high temperature emitted from surrounding the substation. When a fire breaks out due to excessive temperature, the heat dissipation window is fully opened, and the energy storage box is pushed to the farthest distance, and the water-based fire extinguisher extinguishes the fire inside to avoid spreading to the vicinity of the substation, which has a good protective effect on the substation itself.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A grid box-type substation with an energy storage effect includes a box-type substation body. A storage box is provided on the back of the box-type substation body. Two box doors are rotatably installed on the back of the storage box. Slide rail frames are fixed on both sides inside the storage box. A carrier is installed on the slide rail frame, and the carrier is arranged in layers. Battery packs are placed inside each layer of the carrier. Operation windows are opened at positions corresponding to the backs of the battery packs on the carrier. Connecting devices are fixedly installed on the front surface of the carrier. One end of the connecting device is connected to the battery pack, and the other end of the connecting device is connected to the inside of the box-type substation body through a cable. Heat dissipation windows are equidistantly opened on both sides of the storage box. Driving components are provided on the side surfaces of the box-type substation body and the storage box. The driving component includes a cross plate. Two groups of cross plates are symmetrically and slidably installed inside the heat dissipation window, and the cross plates are all connected with a blocking cloth. The blocking cloth blocks the heat dissipation window outside the two cross plates. Two groups of spraying plates are symmetrically installed on the top inner wall of the storage box. Two groups of water-based fire extinguishers are fixedly installed on the top of the storage box. The output ends of the water-based fire extinguishers are controlled by solenoid valves and communicated with the spraying plates.

[0007] Furthermore, a chassis is fixed at the bottom of the box-type substation body. The front end of the storage box can be lapped on the rear end of the chassis, and moving feet are installed at the four corners of the bottom of the storage box.

[0008] Furthermore, a top eaves is fixed at the top of the box-type substation body. A secondary eaves is fixed at the top of the storage box, and the secondary eaves can be butted with the top eaves to form a whole.

[0009] Furthermore, sliding grooves are symmetrically opened on the bottom inner wall of the storage box. Sliding wheels are installed at the bottom of the carrier. The sliding wheels slide along the sliding grooves. Fixing rods are fixed at the four corners of the front end of the carrier, and the fixing rods slide out of the storage box and are fixedly connected to the back of the box-type substation body.

[0010] Furthermore, a cable connecting pipe is fixed between the back of the box-type substation body and the connecting device. A cable passes through the interior of the cable connecting pipe, and the cable connecting pipe is slidably inserted into the energy storage box.

[0011] Furthermore, the driving assembly further includes electric push rods. The electric push rods are fixed on the outer walls on both sides of the box-type substation body, and the extending ends of the electric push rods are fixedly connected to the outer wall of the energy storage box. At the top on both sides of the energy storage box, a first gear is rotatably installed through a shaft rod. The bottom of the first gear is meshed with a first toothed plate, and the first toothed plate is fixed on the outer surface of the box-type substation body.

[0012] Furthermore, a second gear is fixed inside the first gear. One side of the second gear is meshed with a second toothed plate, and the other side of the second gear is meshed with a third toothed plate.

[0013] Furthermore, connecting frames are fixed at the bottoms of the second toothed plate and the third toothed plate, and vertical plates are fixed at the other ends of the connecting frames. The vertical plates on both sides of the heat dissipation window are respectively fixedly connected to the upper and lower groups of cross plates.

[0014] Furthermore, storage grooves are formed in the inner walls of the energy storage box at the upper and lower ends of the heat dissipation window. A winding roller is rotatably installed in the storage grooves through bearings and torsion springs, and the blocking cloth is wound on the winding roller.

[0015] Furthermore, a contact block is fixed at the top of the vertical plate of the second toothed plate, and a contact switch is fixed on the outer wall of the energy storage box corresponding to the top of the contact block.

[0016] Advantages of the present invention:

[0017] The electric push rod of the present invention can push the energy storage box away according to the temperature value detected by the temperature sensor. When the detected temperature reaches the maximum temperature, the heat dissipation window is fully opened at this time, and the contact block at the top of the vertical plate will contact the contact switch. The contact switch is connected to the solenoid valve of the water-based fire extinguisher. After the electrical signal is transmitted, the water-based fire extinguisher extinguishes the fire inside the energy storage box through the spraying plate, avoiding the explosion of the battery.

[0018] When the energy storage box is close to the box-type substation body, the two cross plates are at the closest distance. At this time, there is still a part of the space between the two cross plates for normal heat dissipation and air circulation. The excess part is blocked by the blocking cloth, which can reduce the entry of dust. When the temperature inside the energy storage box rises, the electric push rod pushes the energy storage box away from the box-type substation body. As the energy storage box moves, the first gear meshes with the first toothed plate to drive the second gear to rotate synchronously. The second toothed plate and the third toothed plate respectively mesh with both sides of the second gear and move synchronously in the opposite direction. The vertical plates at the bottom of its connecting frame are respectively connected to the cross plates of the upper and lower layers of the heat dissipation window, thereby driving the two cross plates to move away from each other. The blocking cloth is wound by the winding roller in the storage groove, and the opening of the heat dissipation window is enlarged for better heat dissipation.

[0019] In the present invention, since the bearing frame is connected to the box-type substation body through the fixing rod, when the driving component pushes the energy storage box outwards, the position of the bearing frame will not be affected. The sliding wheels at the bottom of the bearing frame slide along the sliding groove, and there is also a part of the moving space reserved at the front end of the energy storage box located on the bearing frame. The cables connecting the connecting device to the inside of the box-type substation body will not be interfered inside the cable connecting pipe, maintaining the connection relationship. At the same time, the high temperature or spontaneous combustion generated by the battery will not affect the box-type substation body, and the connecting cables are protected by the cable connecting pipe.

[0020] When the energy storage box is close to the box-type substation body, the bottom of the energy storage box is lapped on the chassis and can move along the ground through the moving feet away from the box-type substation body, thereby avoiding the high temperature or spontaneous combustion inside the energy storage box from affecting the internal components of the substation. The cooperation of the top eaves and the secondary eaves can jointly guide rainwater after docking.

[0021] Compared with the prior art, in the present invention, under the action of the driving component, when the temperature inside the energy storage box is relatively high, it is pushed away from the box-type substation body. During this process, the opening of the heat dissipation window becomes larger, improving the ability of air flow and heat dissipation, reducing the temperature inside the energy storage box and avoiding the high temperature emitted from surrounding the substation. When a fire breaks out due to excessive temperature, the heat dissipation window is fully opened, and the energy storage box is pushed to the farthest distance, and the water-based fire extinguisher is used to extinguish the fire inside to avoid spreading to the vicinity of the substation, which has a good protective effect on the substation itself.

Specific embodiments

[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Please refer to Figures 1 to 8, the present invention provides a technical solution: a grid box-type substation with an energy storage effect, including a box-type substation body 1. A storage box 2 is provided on the back of the box-type substation body 1. Two box doors 24 are rotatably installed on the back of the storage box 2. Slide rail frames 25 are fixed on both sides inside the storage box 2. A carrier frame 26 is installed on the slide rail frames 25, and the carrier frame 26 is arranged in layers. Battery packs 5 are placed inside each layer of the carrier frame 26. Operation windows 27 are provided at positions corresponding to the backs of the battery packs 5 on the carrier frame 26. Connecting devices 212 are fixedly installed on the front surface of the carrier frame 26. One end of the connecting device 212 is connected to the battery pack 5, and the other end of the connecting device 212 is connected to the inside of the box-type substation body 1 through a cable. Heat dissipation windows 23 are equidistantly provided on both sides of the storage box 2. Driving components 3 are provided on the side surfaces of the box-type substation body 1 and the storage box 2. The driving component 3 includes a cross plate 39. Two groups of cross plates 39 are symmetrically and slidably installed inside the heat dissipation window 23, and the cross plates 39 are each connected to a blocking cloth 312. The blocking cloth 312 blocks the heat dissipation windows 23 outside the two cross plates 39. Two groups of spraying plates 41 are symmetrically installed on the top inner wall of the storage box 2. Two groups of water-based fire extinguishers 4 are fixedly installed on the top of the storage box 2. The output end of the water-based fire extinguisher 4 is controlled by an electromagnetic valve and communicated with the spraying plate 41. When using the device, the storage box 2 is installed on the periphery of the box-type substation body 1, the battery packs 5 are installed on the carrier frame 26 inside the storage box 2, and the battery packs 5 store the current transmitted by the box-type substation body 1. The temperature inside the storage box 2 is detected by a temperature sensor 42. When the temperature inside the storage box 2 is relatively high, the driving component 3 pushes the storage box 2 away from the box-type substation body 1 and opens the heat dissipation windows 23 to improve the heat dissipation effect.

[0033] In this embodiment, a chassis 11 is fixed at the bottom of the box-type substation body 1. The front end of the storage box 2 can be lapped on the rear end of the chassis 11. Moving feet 22 are installed at the four corners of the bottom of the storage box 2. A top eaves 12 is fixed at the top of the box-type substation body 1. A secondary eaves 21 is fixed at the top of the storage box 2, and the secondary eaves 21 can be butted with the top eaves 12 to form an integral body. When the storage box 2 is close to the box-type substation body 1, the bottom of the storage box 2 is lapped on the chassis 11 and can be moved along the ground through the moving feet 22 away from the box-type substation body 1, so as to prevent the high temperature or spontaneous combustion inside the storage box 2 from affecting the internal components of the substation. The cooperation of the top eaves 12 and the secondary eaves 21 can jointly play the role of guiding rainwater after docking.

[0034] In this embodiment, sliding grooves 28 are symmetrically formed on the inner bottom wall of the energy storage box 2, and sliding wheels 29 are installed at the bottom of the carrier 26. The sliding wheels 29 slide along the sliding grooves 28. Fixing rods 211 are fixed at the four corners of the front end of the carrier 26, and the fixing rods 211 slide out of the energy storage box 2 and are fixedly connected to the back surface of the box-type substation body 1. A cable connection pipe 210 is fixed between the back surface of the box-type substation body 1 and the connection device 212. A cable passes through the interior of the cable connection pipe 210, and the cable connection pipe 210 is slidably inserted into the energy storage box 2. Since the carrier 26 is connected to the box-type substation body 1 through the fixing rods 211, when the driving assembly 3 pushes the energy storage box 2 outwards, the position of the carrier 26 will not be affected. The sliding wheels 29 at the bottom of the carrier 26 slide along the sliding grooves 28, and a part of the moving space is also reserved at the front end of the energy storage box 2 where the energy storage box 2 is located on the carrier 26. The cables connecting the connection device 212 and the interior of the box-type substation body 1 will not be disturbed inside the cable connection pipe 210, maintaining the connection relationship. At the same time, the high temperature or spontaneous combustion generated by the battery will not affect the box-type substation body 1. The cable connection pipe 210 protects the connected cables. The connection device 212 can be an inverter and an intelligent control system for managing the energy flow in the existing energy storage technology, etc.

[0035] In this embodiment, the driving assembly 3 further includes an electric push rod 31. The electric push rods 31 are fixed on the outer walls on both sides of the box-type substation body 1, and the extending ends of the electric push rods 31 are fixedly connected to the outer wall of the energy storage box 2. The top of both sides of the energy storage box 2 is rotatably installed with a first gear 33 through a shaft rod. The bottom of the first gear 33 is meshed with a first toothed plate 32, and the first toothed plate 32 is fixed on the outer surface of the box-type substation body 1. A second gear 34 is fixed inside the first gear 33. One side of the second gear 34 is meshed with a second toothed plate 35, and the other side of the second gear 34 is meshed with a third toothed plate 36. The bottoms of the second toothed plate 35 and the third toothed plate 36 are both fixed with connecting frames 37, and the other ends of the connecting frames 37 are fixed with vertical plates 38. The vertical plates 38 on both sides of the heat dissipation window 23 are respectively fixedly connected to the upper and lower groups of cross plates 39. The inner walls of the energy storage box 2 at the upper and lower ends of the heat dissipation window 23 are provided with storage grooves 310, and a winding roller 311 is rotatably installed in the storage grooves 310 through bearings and torsion springs. The blocking cloth 312 is wound on the winding roller 311. When the energy storage box 2 is close to the box-type substation body 1, the two cross plates 39 are at the closest distance. At this time, there is still a part of the space between the two cross plates 39 for normal heat dissipation and air circulation, and the excess part is blocked by the blocking cloth 312, which can reduce the entry of dust. When the temperature inside the energy storage box 2 rises, the electric push rod 31 pushes the energy storage box 2 away from the box-type substation body 1. As the energy storage box 2 moves, the first gear 33 meshes with the first toothed plate 32 to drive the second gear 34 to rotate synchronously. The second toothed plate 35 and the third toothed plate 36 respectively mesh with the two sides of the second gear 34 and move synchronously and in opposite directions. The vertical plates 38 at the bottoms of their connecting frames 37 are respectively connected to the cross plates 39 on the upper and lower layers of the heat dissipation window 23, thereby driving the two cross plates 39 to move away from each other. The blocking cloth 312 is wound by the winding roller 311 in the storage groove 310, and the opening of the heat dissipation window 23 is enlarged to facilitate better heat dissipation.

[0036] In this embodiment, a contact block 44 is fixed to the top of the vertical plate 38 of the second toothed plate 35. A contact switch 43 is fixed to the top of the energy storage box 2 corresponding to the contact block 44. The electric push rod 31 pushing the energy storage box 2 away can be determined according to the temperature value detected by the temperature sensor 42. When the detected temperature reaches the maximum temperature, at this time the heat dissipation window 23 is fully opened, and the contact block 44 at the top of the vertical plate 38 will contact the contact switch 43. The contact switch 43 is connected to the solenoid valve of the water-based fire extinguisher 4. After the electrical signal is transmitted, the water-based fire extinguisher 4 extinguishes the fire inside the energy storage box 2 through the spray plate 41 to prevent the battery from exploding.

[0037] When using the device, an energy storage box 2 is installed on the periphery of the box-type substation body 1. The battery pack 5 is installed on the carrier 26 inside the energy storage box 2. The battery pack 5 stores the current transmitted by the box-type substation body 1. The temperature sensor 42 is used to detect the internal temperature of the energy storage box 2. When the internal temperature of the energy storage box 2 is relatively high and the energy storage box 2 is close to the box-type substation body 1, the two cross plates 39 are at the closest distance. At this time, there is still a part of the space between the two cross plates 39 for normal heat dissipation and air circulation, and the excess part is blocked by the blocking cloth 312, which can reduce the entry of dust. When the internal temperature of the energy storage box 2 rises, the electric push rod 31 pushes the energy storage box 2 away from the box-type substation body 1. As the energy storage box 2 moves, the first gear 33 meshes with the first toothed plate 32 to drive the second gear 34 to rotate synchronously. The second toothed plate 35 and the third toothed plate 36 respectively mesh with both sides of the second gear 34 and move synchronously in opposite directions. The vertical plates 38 at the bottom of the connecting frame 37 are respectively connected to the cross plates 39 on the upper and lower layers of the heat dissipation window 23, thereby driving the two cross plates 39 to move away from each other. The blocking cloth 312 is wound by the winding roller 311 in the storage groove 310, and the opening of the heat dissipation window 23 is enlarged to facilitate better heat dissipation. The electric push rod 31 pushing the energy storage box 2 away can be determined according to the temperature value detected by the temperature sensor 42. When the detected temperature reaches the maximum temperature, the heat dissipation window 23 is completely opened at this time. The contact block 44 at the top of the vertical plate 38 will contact the contact switch 43. The contact switch 43 is connected to the solenoid valve of the water-based fire extinguisher 4. After the electrical signal is transmitted, the water-based fire extinguisher 4 extinguishes the inside of the energy storage box 2 through the spray plate 41 to prevent the battery from exploding. Since the carrier 26 is connected to the box-type substation body 1 through the fixing rod 211, when the driving assembly 3 pushes the energy storage box 2 outwards, the position of the carrier 26 will not be affected. The sliding wheels 29 at the bottom of the carrier 26 slide along the sliding groove 28, and there is also a part of the moving space reserved at the front end of the energy storage box 2 located on the carrier 26. The cable connecting the connecting device 212 to the inside of the box-type substation body 1 will not be interfered inside the cable connecting pipe 210, maintaining the connection relationship. At the same time, the high temperature or spontaneous combustion generated by the battery will not affect the box-type substation body 1.
