Description

Technical Field

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

[0002] Energy storage substation is a kind of power facility that integrates energy storage, conversion and regulation functions. Its main function is to store energy in energy storage devices to supply the power system for feedback and supplement when needed, so as to achieve the balance and stable operation of the power system. The main components of energy storage substation include: energy storage equipment, inverter, intelligent control system and substation, etc.

[0003] In energy storage substations, energy storage devices are usually battery packs for storing electrical energy, such as lithium-ion batteries, sodium-sulfur batteries, supercapacitors, etc. When charging, the external power system inputs current for charging, and the external energy is stored in the energy storage device; when the load needs to be powered, the energy storage device can release this part of the electrical energy through the electronic control system; inverter conversion energy: inverter is usually a device used to convert direct current into alternating current. In energy storage substations, inverters are mainly used to convert direct current stored in energy storage devices into alternating current to supply the electrical energy required by the power grid or load; intelligent control system manages energy flow: the intelligent control system of the energy storage substation can monitor the operating status of the power system and the charging and discharging status of the energy storage device, and adjust the amount of electrical energy added or output in real time to ensure the stability and reliability of the power system operation. For example, when the voltage or current fluctuates in the power system, the intelligent control system can adjust the charging and discharging amount of the energy storage to balance the supply and demand of electrical energy and ensure the quality and stability of electricity; substation connected 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 AC power of the power grid to the inverter for charging or current feedback operation. In this way, the energy storage substation can support and stabilize the power system, which is of great significance to improving the quality and efficiency of power and reducing energy waste.

[0004] Energy storage substations need to be equipped with battery packs for energy storage, but this method requires additional battery equipment to be installed in outdoor substations. Batteries themselves are flammable and explosive in outdoor environments, and are highly dangerous when installed together with substations. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a grid box-type substation with energy storage effect to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through the action of the driving component, when the temperature inside the energy storage box is high, it is pushed away from the box-type substation body. In this process, the opening of the heat dissipation window becomes larger, which improves the ability of air flow and heat dissipation, reduces the temperature inside the energy storage box and prevents the high temperature from surrounding the substation. When the temperature is too high and a fire occurs, the heat dissipation window is fully opened, the energy storage box is pushed to the farthest distance, and a water-based fire extinguisher is used to extinguish the fire inside to prevent the fire from spreading to the vicinity of the substation, which has a good protection effect on the substation itself.

The energy storage box is connected to a group, 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 provided on both sides of the energy storage box. A driving assembly is provided on the surface of both sides of the box-type substation body and the energy storage box. The driving assembly includes a horizontal plate. Two groups of horizontal plates are symmetrically slidably installed inside the heat dissipation window, and the horizontal plates are connected to baffles. The baffles shield the heat dissipation windows on the outsides of the two horizontal plates. Two groups of spray plates are symmetrically installed on the top inner wall of the energy storage box, and two groups of water-based fire extinguishers are fixedly installed on the top of the energy storage box, and the output end of the water-based fire extinguisher is connected to the spray plate through the control of an electromagnetic valve.

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

[0008] Furthermore, a top eave is fixed on the top of the box-type substation body, a secondary eave is fixed on the top of the energy storage box, and the secondary eave can be connected with the top eave to form a whole.

[0009] Furthermore, the bottom inner wall of the energy storage box is symmetrically provided with sliding grooves, and the bottom of the supporting frame is equipped with sliding wheels, the sliding wheels slide along the sliding grooves, and fixing rods are fixed at the four corners of the front end of the supporting frame, and the fixing rods slide out of the energy storage box and are fixedly connected to the back of the box-type substation body.

[0010] Furthermore, a cable connection tube is fixed between the back side of the box-type substation body and the connection device, the cable passes through the inside of the cable connection tube, and the cable connection tube is slidably plugged into the energy storage box.

[0011] Furthermore, the driving assembly also includes an electric push rod, which is fixed on the outer walls of both sides of the box-type substation body, and the extended end of the electric push rod is fixedly connected to the outer wall of the energy storage box, and the first gear is rotatably installed on the top of both sides of the energy storage box through an axis rod, and the top of the first gear is meshed with a first tooth plate, and the first tooth plate is fixed on the outer surface of the box-type substation body.

[0012] Furthermore, a second gear is fixed on the inner side of the first gear, one side of the second gear is meshedly connected with a second gear plate, and the other side of the second gear is meshedly connected with a third gear plate.

[0013] Furthermore, a connecting frame is fixed to the bottom of the second tooth plate and the third tooth plate, and a vertical plate is fixed to the other end of the connecting frame. The vertical plates on both sides of the heat dissipation window are fixedly connected to the upper and lower sets of horizontal plates respectively.

[0014] Furthermore, the energy storage box is provided with a storage groove on the inner wall located at the upper and lower ends of the heat dissipation window, and a winding roller is rotatably installed inside the storage groove through a bearing and a torsion spring, and the baffle cloth is wound on the winding roller.

[0016] Beneficial effects of the present invention:

[0017] 1. The distance to which the electric push rod of the present invention pushes the energy storage box can be determined according to the temperature value detected by the temperature sensor. When the temperature is detected to reach the maximum temperature, the heat dissipation window is fully opened, and the contact block on 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 spray plate to avoid battery explosion.

[0018] 2. In the present invention, when the energy storage box is close to the box-type substation body, the two horizontal plates are at the shortest distance. At this time, there is still a part of space between the two horizontal plates for normal heat dissipation and air circulation, and 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 tooth plate to drive the second gear to rotate synchronously, and the second tooth plate and the third tooth plate respectively mesh with the two sides of the second gear and move synchronously in opposite directions. The vertical plates at the bottom of the connecting frame are respectively connected to the horizontal plates of the upper and lower layers of the heat dissipation window, thereby driving the two horizontal plates to move away from each other, and the blocking cloth is rolled up by the winding roller in the storage groove to enlarge the opening of the heat dissipation window for better heat dissipation.

[0019] 3. In the present invention, since the support frame is connected to the box-type substation body through a fixed rod, when the driving component pushes the energy storage box outward, it will not affect the position of the support frame. The sliding wheel at the bottom of the support frame slides along the slide groove, and the energy storage box is located at the front end of the support frame and a part of the moving space is reserved. The cable connecting the connecting device and the inside of the box-type substation body will not be disturbed inside the cable connecting pipe, and the connection relationship is maintained. At the same time, the high temperature or spontaneous combustion generated by the battery will not affect the box-type substation body, and the connected cables are protected by the cable connecting pipe.

[0020] 4. In the present invention, when the energy storage box is close to the box-type substation body, the bottom of the energy storage box is overlapped on the chassis, and can be moved along the ground by moving the feet, away from the box-type substation body, thereby avoiding the high temperature or spontaneous combustion inside the energy storage box affecting the internal components of the substation. The top eaves and the side eaves can work together to guide rainwater after docking.

[0021] 5. Compared with the prior art, the present invention, through the action of the driving component, pushes the energy storage box away from the box-type substation body when the internal temperature of the energy storage box is high. In this process, the opening of the heat dissipation window becomes larger, thereby improving the ability of air flow and heat dissipation, reducing the temperature inside the energy storage box and preventing the high temperature from surrounding the substation. When the temperature is too high and a fire occurs, the heat dissipation window is fully opened, the energy storage box is pushed to the farthest distance, and a water-based fire extinguisher is used to extinguish the fire inside to prevent the fire from spreading to the vicinity of the substation, thereby having a better protection effect on the substation itself.

The vertical plates 38 on both sides of the heat dissipation window 23 are respectively fixedly connected to the upper and lower groups of horizontal plates 39. The energy storage box 2 is provided with a storage groove 310 on the inner wall located at the upper and lower ends of the heat dissipation window 23, and the storage groove 310 is provided with a plurality of storage grooves 310. The wind-up roller 311 is rotatably mounted on the part through bearings and torsion springs, and the blocking cloth 312 is rolled up on the wind-up 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 shortest distance. At this time, there is still a part of space between the two cross plates 39 for normal heat dissipation and air circulation. The excess part is blocked by the blocking cloth 312 to 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. With the movement of the energy box 2, the first gear 33 meshes with the first tooth plate 32 to drive the second gear 34 to rotate synchronously, the second tooth plate 35 and the third tooth plate 36 respectively mesh with the two sides of the second gear 34 and move synchronously in the opposite direction, and the vertical plate 38 at the bottom of the connecting frame 37 is respectively connected to the horizontal plates 39 of the upper and lower layers of the heat dissipation window 23, thereby driving the two horizontal plates 39 to move away from each other, and the blocking cloth 312 is rolled up by the winding roller 311 in the storage groove 310 to enlarge the opening of the heat dissipation window 23 for better heat dissipation.

[0036] In this embodiment, a contact block 44 is fixed on the top of the vertical plate 38 of the second tooth plate 35, and a contact switch 43 is fixed on the top of the contact block 44 corresponding to the outer wall of the energy storage box 2.

When the temperature reaches the maximum temperature, the heat dissipation window 23 is fully opened, and the contact block 44 on 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 the device is used, an energy storage box 2 is installed on the periphery of the box-type substation body 1, and a battery pack 5 is installed on a support frame 26 inside the energy storage box 2. The battery pack 5 stores the current delivered by the box-type substation body 1, and the internal temperature of the energy storage box 2 is detected by the temperature sensor 42. When the internal temperature of the energy storage box 2 is high, when the energy storage box 2 is close to the box-type substation body 1, the two horizontal plates 39 are at the shortest distance. At this time, there is still a part of space between the two horizontal plates 39 for normal heat dissipation and air circulation, and the excess part is covered by the blocking cloth 312. The energy storage box 2 is blocked to 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 tooth plate 32 to drive the second gear 34 to rotate synchronously. The second tooth plate 35 and the third tooth plate 36 respectively mesh with the two sides of the second gear 34 and move synchronously in the opposite direction.

The winding roller 311 in the middle is wound up to enlarge the opening of the heat dissipation window 23 for better heat dissipation. The distance of the electric push rod 31 pushing the energy storage box 2 can be determined according to the temperature value detected by the temperature sensor 42. When the temperature is detected to reach the maximum temperature, the heat dissipation window 23 is fully opened, and the contact block 44 on 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 avoid battery explosion. Because the support frame 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 outward, it will not affect the position of the support frame 26. The sliding wheel 29 at the bottom of the support frame 26 slides along the slide groove 28, and the energy storage box 2 is located at the front end of the support frame 26 and some moving space is reserved.
