Description

Technical Field

[0001] This utility model relates to the technical field of emergency power outage protection equipment, and in particular to an emergency distributed power outage protection device for computer room engineering. Background Technology

[0002] Currently, mainstream emergency power-off solutions for data centers generally employ a combination of electronic sensing and electrical control. Specifically, fire detection typically involves distributing electronic smoke detectors, heat detectors, and other fire sensors throughout the data center. When a sensor detects an abnormal signal, it sends a signal to the intelligent control unit in the power distribution system via an electrical circuit. This control unit then drives the shunt trip unit or contactor installed in the power distribution circuit to achieve remote automatic power disconnection. This technical approach is highly dependent on a stable power supply and complex signal transmission and control logic.

[0003] There is a fundamental vulnerability in the existing technology: its effective operation depends on the power supply system and control lines remaining intact in the early stages of a fire. In actual fires, the fire may originate precisely from the electrical lines or equipment themselves. The high temperature and smoke generated can easily lead to power outages or burnout of control lines in the early stages, thus paralyzing the entire electronic control system and making it unable to execute the predetermined power outage procedure, posing a huge safety hazard. Utility Model Content

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1 - Figure 5 This utility model discloses an emergency distributed power outage protection device for computer room engineering, comprising:

[0029] Equipment outer frame 1, vertical plate 2, thermal drive assembly 3, transmission assembly 4, and tripping execution assembly 5;

[0030] The upright plate 2 is installed inside the outer frame 1 of the equipment, with a bottom shaft 6 rotatably installed at its bottom end and a top shaft 7 rotatably installed at its top end;

[0031] The heat-driven assembly 3 includes a heating chamber 31, a guide rod 32 and a toothed plate 33. The heating chamber 31 is disposed on the side wall of the vertical plate 2, the guide rod 32 is slidably disposed inside the top end of the heating chamber 31, and the toothed plate 33 is fixed to the top end of the guide rod 32.

[0032] The transmission assembly 4 includes a driven gear 41, an eccentric shaft 42, and a guide groove 43. The driven gear 41 is coaxially and fixedly connected to the top shaft 7 and meshes with the gear plate 33. The eccentric shaft 42 is connected to the top shaft 7 through a connecting rod. The guide groove 43 is opened inside the vertical plate 2, is arc-shaped and coaxial with the top shaft 7, and one end of the eccentric shaft 42 is slidably disposed in the guide groove 43.

[0033] The tripping execution assembly 5 includes a drive gear 51 and a knife switch 52. The drive gear 51 is rotatably mounted on the side wall of the vertical plate 2 and meshes with the driven gear 41. The knife switch 52 is fixed to one side of the drive gear 51.

[0034] A reset assembly 8 is provided between the eccentric shaft 42 and the bottom shaft 6.

[0035] In this embodiment, when the internal temperature of the device is within the normal range, the device is in a closed standby state.

[0036] At this time, the tension spring 82 in the reset assembly 8 is in a stretched and stored state. The tension of the tension spring 82 acts on the eccentric shaft 42 and the bottom shaft 6 respectively through the two sleeves 81, tightly holding the shaft at one end of the eccentric shaft 42 and pressing it against the tail end of the arc-shaped guide groove 43, as shown. Figure 5 As shown, in this state, the top shaft 7 and the driven gear 41 fixed thereto are locked, the transmission system remains stable, the drive gear 51 keeps the switch 52 in the closed position, and the circuit is connected.

[0037] When abnormal temperature rise occurs inside the equipment in the computer room, such as electrical short circuit or equipment overheating, the heat will be conducted to the heating chamber 31 of the heat drive component 3. The oil-based thermal expansion medium filled in the chamber expands rapidly after being heated, generating strong pressure. This pressure pushes the guide rod 32 upward, causing the toothed plate 33 fixed at its top to move upward in a straight line.

[0038] The upward-moving toothed plate 33 meshes with the driven gear 41, converting it into the rotational motion of the driven gear 41. The driven gear 41 drives the top shaft 7 to rotate synchronously. The top shaft 7 drives the eccentric shaft 42 to start rotating around the axis of the top shaft 7 through the connecting rod. At the same time, the shaft at one end of the eccentric shaft 42 is forced to slide from the tail end of the guide groove 43 to the top end. This process requires overcoming the tension of the tension spring 82.

[0039] The highest point of the arc-shaped guide groove 43 constitutes the mechanical critical point. When the shaft of the eccentric shaft 42 slides past this critical point, the mechanical balance of the entire mechanism is instantly broken. The direction of the tension force of the previously overcome tension spring 82 now becomes the direction that pushes the eccentric shaft 42 to accelerate. The accumulated elastic potential energy is released instantly, generating a huge acceleration that drives the shaft to slide rapidly down the guide groove 43. Figure 4 As shown, the linkage mechanism forces the top shaft 7 and the driven gear 41 to complete the rapid rotation of the remaining angle. The driven gear 41 drives the drive gear 51 meshing with it to rotate, which in turn drives the switch 52 fixed on it to swing at an extremely fast speed, thereby achieving mechanical opening and completely cutting off the circuit.

[0040] When the internal temperature of the equipment rises abnormally, the oil-based thermal expansion medium in the heating chamber 31 is heated and pushes the guide rod 32 upward, which drives the toothed plate 33 to drive the driven gear 41 to rotate. Then, through the sliding of the eccentric shaft 42 in the arc-shaped guide groove 43, the mechanism achieves the movement of the critical point. Finally, under the energy storage and release of the tension spring 82, the switch 52 is driven to achieve rapid opening. The rapid opening of the switch 52 by controlling the internal temperature of the equipment is suitable for the computer room to achieve reliable emergency power-off protection in extreme situations such as fire, which can effectively improve the stability of the equipment.

[0041] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the reset assembly 8 includes two sleeves 81 and a tension spring 82. The two sleeves 81 are rotatably disposed on the outer periphery of the eccentric shaft 42 and the bottom shaft 6, respectively. The two ends of the tension spring 82 are fixedly connected to the outer walls of the two sleeves 81, respectively.

[0042] In this embodiment, the reset assembly 8 consists of two sleeves 81 and a tension spring 82. The two sleeves 81 are respectively loosely fitted around the outer periphery of the eccentric shaft 42 and the bottom shaft 6, and can rotate independently. The two ends of the tension spring 82 are respectively fixed on the outer walls of the two sleeves 81. In the closed state, the spring is in a stretched state, and the tension it generates is converted into a torque on the eccentric shaft 42 through the sleeves 81, which presses the shaft at the end of the eccentric shaft 42 tightly against the tail end of the guide groove 43, forming a stable closing holding force.

[0043] When the thermal drive component 3 pushes the mechanism past the critical point, the tension of the spring changes to drive the eccentric shaft 42 to accelerate, quickly completing the opening action. This ensures the swiftness and decisiveness of the opening action, effectively extinguishing the electric arc. The use of sleeve 81 in conjunction with the shaft avoids wear of the spring under torsional deformation, ensuring the efficiency of force transmission and the service life of the mechanism.

[0044] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the heating chamber 31 is filled with a thermal expansion medium, wherein the thermal expansion medium is an oil-based medium.

[0045] In this embodiment, the oil medium is filled in the sealed heating chamber 31. Based on the physical property that the coefficient of thermal expansion of liquid is much greater than that of solid, when the ambient temperature of the computer room rises abnormally, the heat is conducted to the oil through the wall of the heating chamber 31, causing its heated volume to expand significantly. Since the chamber is sealed, the incompressible oil generates pressure, which acts directly on the bottom of the guide rod 32, pushing the guide rod 32 to move upward in a straight line.

[0046] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the side wall of the upright plate 2 is provided with a gear cover 9 to protect the gear.

[0047] In this embodiment, the gear cover 9 is a protective cover that is fixed to the side wall of the upright plate 2 with screws. It completely covers the driven gear 41 and the drive gear 51 and other transmission components, forming a relatively sealed space. This isolates the gear meshing area from the external environment, effectively keeping out dust and fibers in the machine room environment. This avoids problems such as gear jamming, increased transmission resistance, or even inability to move due to dust accumulation, effectively ensuring the reliability of the transmission system at critical moments and greatly reducing the maintenance requirements of the device.

[0048] In a further preferred embodiment of this utility model, such as Figure 2 As shown, a baffle 10 is provided on the outer peripheral wall of the top shaft 7. The baffle 10 is coaxially arranged with the top shaft 7 and corresponds to the position of the guide groove 43. A limit ring 11 is rotatably provided on the outer peripheral side of the baffle 10. The limit ring 11 is fixedly connected to the vertical plate 2 by bolts.

[0049] In this embodiment, the baffle 10 is coaxially fixed with the top shaft 7 and rotates together with the top shaft 7. The circular disc surface of the baffle 10 always covers the outer opening of the guide groove 43. No matter what angle the top shaft 7 rotates to, it can effectively shield the guide groove 43. The limiting ring 11 is fixed to the vertical plate 2 by bolts. It restricts the baffle 10 in the narrow gap between it and the vertical plate 2, ensuring that the baffle 10 can only rotate and will not move axially, thus maintaining its sealing effect.

[0050] The implementation principle of the above embodiment is as follows: When the internal temperature of the equipment rises abnormally, the oil thermal expansion medium in the heating chamber 31 is heated and pushes the guide rod 32 upward, which drives the toothed plate 33 to drive the driven gear 41 to rotate. Then, the eccentric shaft 42 slides in the arc-shaped guide groove 43 to realize the movement of the mechanism through the critical point. Finally, under the energy storage and release action of the tension spring 82, the switch 52 is driven to achieve rapid opening. The rapid opening of the switch 52 by controlling the internal temperature of the equipment is suitable for the computer room to achieve reliable emergency power outage protection in extreme situations such as fire, which can effectively improve the stability of the equipment.

[0051] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
