Description

Technical Field

[0001] This utility model belongs to the field of substation equipment technology, specifically, it relates to a ventilation device for a substation battery room. Background Technology

[0002] The ventilation system in the substation battery room is a specially designed explosion-proof mechanical ventilation system used to solve the problem of hydrogen accumulation generated during battery charging and discharging, prevent the risk of explosion, and maintain a suitable temperature environment.

[0003] The prior art discloses a ventilation device for a substation battery room (CN202123427576.0). An auxiliary ventilation structure is installed between the right side wall of the main body of the battery room and the bottom of the load-bearing plate. Through holes are opened on the upper and lower sides of the right side wall of the main body of the battery room. An exhaust fan is fixedly installed in the upper through hole, and an intake and exhaust fan is fixedly installed in the lower through hole. A wind-guided support structure is fixedly installed between the bottom surface of the inner cavity of the main body of the battery room and the bottom surface of the load-bearing plate.

[0004] In existing technology, cool air is guided by a wind-driven support structure and then evenly sprayed out from the exhaust vents on the load-bearing plate to cool the battery. However, the battery releases hydrogen gas during charging and discharging, which can explode when it comes into contact with a spark when the concentration is sufficient. Existing technology includes an exhaust fan, but the hydrogen gas rises and accumulates in layers. Furthermore, it lacks explosion-proof design, and the exhaust fan and motor may generate electrical sparks, posing an explosion risk. The single exhaust vent design cannot cover local accumulation areas, creating safety blind spots and failing to ensure that the lower layer of hydrogen gas can be discharged in a timely manner.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the technical problem of ensuring timely discharge of hydrogen from the lower layer, the basic concept of the present invention is as follows: a ventilation device for a substation battery room, including a second chamber, which is located above the ground. The interior of the second chamber is provided with an exhaust vent, which includes several stabilizing and reinforcing structures. Several support plates are provided below the stabilizing and reinforcing structures, and several air passages are opened on one side of each support plate. The rapid hydrogen removal structure is located inside the second chamber. Each of the two sides of the top surface of the second chamber has a movable slot. Each movable slot has a lifting plate that can be raised and lowered according to the hydrogen level. An exhaust fan is installed on one side of one lifting plate, and a square frame is installed in the middle of the other lifting plate.

[0007] In a preferred embodiment of this utility model, each of the two lifting plates is provided with a rack on one side, and each of the two moving slots is provided with a gear. The two gears are rotatably connected to the two sides of the moving slots, and each of the two gears meshes with a rack.

[0008] In a preferred embodiment of this utility model, a sliding groove is provided on one side of the two moving grooves, and a fixed plate is fixed on one side of the two lifting plates. Each of the two fixed plates is slidably connected to a sliding groove. Three openings are provided on both sides of the two moving grooves, and the openings are matched with the size of the exhaust fan and the square frame.

[0009] In a preferred embodiment of this utility model, the rapid hydrogen removal structure further includes a servo motor and a connecting rod. The servo motor is fixedly mounted on one side of the second chamber, and the rotating shaft of the servo motor is fixedly connected to one end of a gear through a coupling. Both ends of the connecting rod are fixedly connected to one end of a gear.

[0010] In a preferred embodiment of this utility model, the rapid hydrogen removal structure further includes an electric telescopic rod and a wind plate. The electric telescopic rod is fixed inside a lifting plate, and the output shaft of the electric telescopic rod is fixedly connected to the top surface of the wind plate through a coupling. The wind plate extends into the middle of the frame and is slidably connected to the frame.

[0011] In a preferred embodiment of the present invention, a protective cover is fixed on the top surface of the two moving slots, one end of the lifting plate is set inside the protective cover, the top surface of the second chamber is fixed with the first chamber, and the top of the first chamber is provided with an inclined top plate.

[0012] In a preferred embodiment of this utility model, an exhaust fan is provided at the bottom corner of one side of the second chamber, and a controller is provided on the other side. The exhaust fan and the electric telescopic rod are electrically connected to the controller. A through hole is provided at the position of the two moving slots near the fixed plate. Three hydrogen sensors are fixed on the inner wall of the second chamber, and the height of the three hydrogen sensors is the same as the height of the three through holes.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The exhaust fan and the frame rise to the same height as the hydrogen sensor opening. The lifting plate blocks the other two openings. Then the controller turns on the power of the exhaust fan and the electric telescopic rod. The electric telescopic rod lifts the air plate out of the frame, and the exhaust fan moves to the designated level to extract the hydrogen from this level.

[0014] 2. When the ventilation is opened in conjunction with this frame, areas with high hydrogen concentration can be quickly dispersed to prevent explosions due to high concentrations. When the hydrogen concentration drops to the set maximum value, the controller will activate the electric telescopic rod to close the air vent.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0019] A ventilation device for a substation battery room, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a rapid hydrogen removal structure is installed inside the second chamber 9. Each of the two sides of the top surface of the second chamber 9 has a movable slot 16. Each movable slot 16 contains a lifting plate 13 that can rise and fall according to the hydrogen level. An exhaust fan 15 is installed on one side of one lifting plate 13, and a square frame 20 is installed in the middle of the other lifting plate 13. A rack 10 is fixed on one side of each of the two lifting plates 13. A gear 14 is installed inside each of the two movable slots 16, and each gear 14 interacts with a movable slot. The two sides of the 16 are rotatably connected, and each of the two gears 14 meshes with a rack 10. A sliding groove 17 is provided on one side of the two moving grooves 16, and a fixed plate 18 is fixed on one side of the two lifting plates 13. Each of the two fixed plates 18 is slidably connected to a sliding groove 17. Three openings 11 are provided on both sides of the two moving grooves 16. The openings 11 match the size of the exhaust fan 15 and the square frame 20. The rapid hydrogen removal structure also includes a servo motor 2 and a connecting rod 12. The servo motor 2 is fixed on one side of the second chamber 9. The rotating shaft of 2 is fixedly connected to one end of a gear 14 via a coupling. Both ends of the connecting rod 12 are fixedly connected to one end of a gear 14. A protective cover 8 is fixedly installed on the top surface of the two moving slots 16. One end of the lifting plate 13 is located inside the protective cover 8. The top surface of the second chamber 9 is fixedly provided with the first chamber 1. The top of the first chamber 1 is provided with an inclined top plate. The rapid hydrogen removal structure also includes an electric telescopic rod 19 and a wind plate 21. The electric telescopic rod 19 is fixedly installed inside a lifting plate 13. The output shaft of the electric telescopic rod 19 passes through... The top surface of the air plate 21 is fixedly connected to the coupling. The air plate 21 extends into the middle of the square frame 20 and is slidably connected to the square frame 20. A ventilation fan is provided at the bottom corner of one side of the second chamber 9, and a controller is provided on the other side. The ventilation fan, exhaust fan 15 and electric telescopic rod 19 are all electrically connected to the controller. A through hole is opened in the two moving slots 16 near the fixed plate 18. Three hydrogen sensors 7 are fixedly installed on the inner wall of the second chamber 9. The height of the three hydrogen sensors 7 is the same as the height of the three through holes 11.

[0020] Three hydrogen sensors 7 are arranged sequentially from top to bottom. When one hydrogen sensor 7 detects that the hydrogen concentration in the current layer is greater than a set range, it sends an electrical signal to the controller. The controller then drives the servo motor 2 to rotate, which in turn drives a gear 14 to rotate. The gear 14 drives the connecting rod 12 and another gear 14 to rotate, causing two racks 10 to lift two lifting plates 13, raising the exhaust fan 15 and the square frame 20 to the same height as the hydrogen sensor 7 at the opening 11. The lifting plates 13 then block the other two openings 11. Subsequently, the controller activates the exhaust fan 15 and the electric telescopic rod. 19 Power supply, electric telescopic rod 19 lifts the air panel 21 out of the frame 20, exhaust fan 15 to the designated level, extracts hydrogen from this level, and opens ventilation in conjunction with the frame 20 at this level. The hydrogen can be quickly dispersed in areas with high concentration, preventing explosions due to high concentrations. The power lines of electric telescopic rod 19 and exhaust fan 15 are connected to the power supply through the through hole. The servo motor, exhaust fan, and electric telescopic rod all adopt ExdIIBT4 level explosion-proof structure. The electrical wiring is laid in sealed galvanized steel pipes, and the interface adopts explosion-proof glands to prevent hydrogen from entering the cable trench. Nitrile rubber sealing strips are embedded in the edge of the lifting plate.

[0021] A ventilation device for a substation battery room, such as Figure 1 and Figure 2 As shown, the second chamber 9 is located above the ground. The interior of the second chamber 9 has an exhaust vent 6, which includes several stabilizing and reinforcing structures 5. Below the stabilizing and reinforcing structures 5 are several support plates 3. Each support plate 3 has several air passage holes 4 on one side. A substation battery room ventilation device also includes a rectangular frame, a base plate, a load-bearing plate, a wind-guided support structure, a support plate positioning seat, a ramp, a support seat, a mesh plate, a rubber layer, an inclined air guide plate, a connecting plate, mounting holes, and an arc-shaped elastic plate. It is worth noting that the rectangular frame, base plate, load-bearing plate, wind-guided support structure, support plate positioning seat, ramp, support seat, and mesh plate... The rubber layer, inclined air guide plate, connecting plate, mounting through hole, arc-shaped elastic plate, support plate, air passage hole, stabilizing and reinforcing structure, exhaust through hole and inclined top plate are all existing technologies, which have been disclosed in a substation battery room ventilation device (CN202123427576.0). The specific implementation method will not be described in detail here. After being guided by the wind-guided support structure, the cold air is evenly sprayed out from the exhaust through hole 5 on the load-bearing plate, which provides targeted ventilation and cooling for the batteries placed on the load-bearing plate, thereby improving the cooling effect. After cooling, the airflow carrying heat rises and is guided by the inclined top plate before being discharged to the outside from the exhaust fan 15, thus forming a ventilation and cooling effect.

[0022] The working principle of this utility model is as follows: After being guided by the wind-guided support structure, the cold air is evenly sprayed out from the exhaust vent 5 on the load-bearing plate, providing targeted ventilation and cooling for the batteries placed on the load-bearing plate. Three hydrogen sensors 7 are arranged sequentially from top to bottom. When one hydrogen sensor 7 detects that the hydrogen concentration in the current layer is greater than the set range, it sends an electrical signal to the controller. The controller drives the servo motor 2 to rotate, which in turn drives one gear 14 to rotate. The gear 14 drives the connecting rod 12 and another gear 14 to rotate, and the two racks 10 drive... The two lifting plates 13 are raised, raising the exhaust fan 15 and the frame 20 to the same height as the hydrogen sensor 7 at the opening 11. The lifting plates 13 cover the other two openings 11. Then the controller turns on the power to the exhaust fan 15 and the electric telescopic rod 19. The electric telescopic rod 19 raises the air panel 21 out of the frame 20. The exhaust fan 15 reaches the designated level and extracts the hydrogen from this level. With the opening of the frame 20 at this level, the hydrogen can be quickly dispersed in areas with higher concentrations. When the hydrogen concentration drops to the set maximum value, the controller activates the electric telescopic rod 19 to close the air panel 21.
