[0001] This utility model relates to a special type of door, specifically a roller shutter door for transformer rooms. Background Technology
[0002] The doors of transformer rooms, as important safety protection facilities, play a crucial role in the operation of power equipment. Currently, transformer room doors generally use the steel doors for transformer rooms as shown in the atlas "17610-1 Special Doors and Windows (I)". These steel doors are all swing doors, but traditional swing doors for transformer rooms are greatly limited by space constraints. When space is limited, such as when the transformer room is too close to a road, the swing door would occupy road space and affect vehicle passage, or due to special requirements from the owner, the door cannot be a swing door and can only be a roller shutter door. Furthermore, traditional roller shutter doors, as shown in "03J611-4 Aluminum Alloy, Color Steel, and Stainless Steel Sandwich Panel Doors", only have a small portion of ventilation slats for ventilation, which cannot meet the ventilation rate requirements of transformer room doors and cannot flexibly provide effective ventilation area according to the heat dissipation of the transformer room.
[0003] In view of this, based on years of experience in production and design in this and related fields, the inventor has designed a roller shutter door for transformer rooms through repeated experiments in order to solve the problems existing in the prior art. Utility Model Content

[0014] Compared with the prior art, the present invention has the following features and advantages:
[0015] This invention proposes a roller shutter door for transformer rooms, the door curtain of which is composed of movable louvers and soft steel wire mesh. This invention employs a motor-driven automatic lifting and lowering opening and closing mechanism for the roller shutter door, which is not limited by the size of the site and can be applied to transformer doors in various locations.

[0033] The details of this utility model can be more clearly understood by referring to the accompanying drawings and the description of specific embodiments. However, the specific embodiments of this utility model described herein are for illustrative purposes only and should not be construed as limiting the utility model in any way. Under the teachings of this utility model, those skilled in the art can conceive of any possible modifications based on this utility model, and these should all be considered to fall within the scope of this utility model.
[0034] like Figures 1 to 6 As shown, this utility model proposes a roller shutter door 1 for a transformer room. The transformer room has at least one vertical side for installing the roller shutter door 1. The upper part of the roller shutter door 1 is provided with a motor device that can pull the roller shutter door 1 up and down. The motor device pulls the curtain panel 11 of the roller shutter door 1 up and down and opens and closes the roller shutter door 1 through the transmission shaft 4 of the motor. The two sides of the roller shutter door 1 are provided with guide rails 2 for the curtain panel 11 to slide up and down. The inner layer of the curtain panel 11 of the roller shutter door 1 is composed of soft steel wire mesh 12. The upper outer layer of the curtain panel 11 is provided with a movable louvered slat layer 13. The movable louvered slat layer 13 and the inner soft steel wire mesh 12 are combined to form a double-layer adjustable ventilation structure. The lower part of the curtain panel 11 is composed of the inner soft steel wire mesh 12 to form a single-layer fixed ventilation structure.
[0035] The roller shutter door 1 proposed in this utility model for transformer rooms overcomes the shortcomings of traditional swing doors for transformer rooms, which are limited by the available space. It can be used in transformer rooms that are suitable for various application site conditions, allowing the door of the transformer room to be opened and closed freely in a small space.
[0036] The roller shutter door 1 for transformer rooms proposed in this utility model overcomes the shortcomings of the prior art, which cannot flexibly provide an effective ventilation area according to the heat dissipation of the transformer room and cannot meet the ventilation rate requirements of the transformer room door.
[0037] The roller shutter door 1 for transformer rooms proposed in this utility model can flexibly adjust the ventilation area of the transformer door according to the ventilation requirements of the transformer, so as to ensure the natural ventilation and heat dissipation requirements of the transformer room.
[0038] The roller shutter door 1 for transformer rooms proposed in this utility model effectively overcomes space limitations by adopting an automatic lifting method driven by a motor, making it particularly suitable for confined areas and solving the problem of the difficulty in installing and using traditional swing doors. The curtain panel 11 is a combination structure of soft steel wire mesh 12 and movable louvered slats 13, which can flexibly adjust the ventilation area according to the real-time heat dissipation needs of the transformer. When the heat dissipation is large, the louvers are opened to increase the ventilation volume, and the louvers are closed in time in case of severe weather or when the heat dissipation is small, ensuring ventilation effect and protective performance.
[0039] In one optional embodiment of this utility model, the height of the fixed ventilation structure formed by the soft steel wire mesh 12 in the lower inner layer of the curtain panel 11 is 800mm, providing a stable basic ventilation area in the lower part of the curtain panel 11. Even when the upper movable louvered curtain layer 13 is closed, the necessary air circulation can still be maintained, avoiding poor heat dissipation caused by the complete sealing of the transformer room.
[0040] Furthermore, the soft wire mesh 12 is aligned with the movable venetian blind slat layer 13 to ensure structural stability.
[0041] In an optional embodiment of this utility model, the venetian blinds of the movable venetian blind layer 13 on the upper outer layer of the curtain panel 11 are individually controlled to open. The movable venetian blind layer 13 is provided on the upper outer layer of the curtain panel 11. The venetian blinds are connected to the frame of the curtain panel 11 by hinges, and the two ends of the pivot of each venetian blind are embedded in the groove of the guide rail 2.
[0042] In an optional embodiment, the electric connector 14, linked to the louver pivot, independently controls the opening and closing of the movable louver slat layer 13. The motor control signal line is integrated with the main circuit of the roller shutter door 1, and the louver angle is independently adjusted via the control switch 5 during operation. By independently controlling the opening and closing of the movable louver slat layer 13 through the electric connector 14, the ventilation rate can be flexibly adjusted according to the actual heat dissipation needs of the transformer room or external environmental conditions. When heat dissipation demand is high, the louvers are opened to achieve maximum ventilation area; in severe weather conditions such as strong winds and heavy rain, the louvers are closed to reduce the impact of the external environment, while maintaining basic ventilation through the inner soft steel wire mesh 12.
[0043] In another alternative embodiment, the opening or closing of the movable venetian blind layer 13 is manually controlled by a lever switch 9.
[0044] In an optional embodiment of this utility model, a cover 3 for storing the movable venetian blind layer 13 is provided above the roller shutter door 1.
[0045] In one alternative embodiment, the inner layer of the soft steel wire mesh 12 of the curtain panel 11 of the roller shutter door 1 and the upper outer layer of movable venetian blinds 13 are respectively controlled to be pulled up and down. The inner layer of soft steel wire mesh 12 is fixedly connected to the bottom frame of the curtain panel 11, and the curtain panel 11 is driven to rise and fall as a whole through the drive shaft 4. The drive shaft 4 is coaxially installed with the roller drum and slides along the guide rail 2 during lifting and lowering. The control circuits of the outer layer of movable venetian blinds 13 and the inner layer of soft steel wire mesh 12 are respectively integrated into the outlet box 6 in the housing 3, and are operated independently by the control switch 5 button. The outer layer of movable venetian blinds 13 is pulled and folded into the housing 3 by the drive shaft 4 to avoid wear or dust accumulation caused by long-term exposure, while realizing rapid adjustment of the ventilation area; the inner layer of soft steel wire mesh 12 is driven to rise and fall by another motor to ensure the stability of the ventilation structure. The separate control design of the two allows the roller shutter door 1 to flexibly select the ventilation mode when it is open, and when it is closed, the outer louvered curtain is retracted to reduce the space occupied, while the inner soft steel wire mesh 12 maintains basic ventilation, which is especially suitable for transformer rooms with limited space.
[0046] In one alternative embodiment, the upper outer layer of movable venetian blinds 13 of the curtain panel 11 adopts an electric venetian structure, which is pulled by a motor to fold and retract into the housing 3 above the roller shutter door 1. The inner layer of soft steel wire mesh 12 is pulled up and down by another motor. The upper outer layer of movable venetian blinds 13 of the curtain panel 11 is connected to the housing 3 through a drive shaft 4. The drive shaft 4 drives the venetian blinds to fold along the guide rail 2 and retract into the housing 3. The top of the housing 3 is provided with a guide groove to ensure stable folding trajectory and to achieve rapid adjustment of ventilation area. The control circuits of the outer venetian blinds and the inner soft steel wire mesh 12 are respectively integrated into the outlet box 6 in the housing 3 and are operated independently by the control switch 5 button. Its separate control design allows the roller shutter door 1 to flexibly select the ventilation mode when it is opened.
[0047] In another optional embodiment, the venetian blinds of the upper outer layer 13 of the curtain panel 11 are manually pulled and folded into the housing 3 above the roller shutter door 1. The upper outer layer 13 of the curtain panel 11 is connected to the housing 3 via a traction rope. By manually pulling the traction rope, the venetian blinds are folded along the guide rail 2 and retracted into the housing 3. The top of the housing 3 is provided with a guide groove to ensure the stability of the folding trajectory. The venetian blinds are connected to the curtain panel 11 frame via hinges. The hinge rotation angle is limited during folding to prevent them from falling off. The inner soft steel wire mesh 12 is fixedly connected to the curtain panel 11 frame and rises and falls with the curtain panel 11 as a whole, sliding along the guide rail 2 during rising and falling.
[0048] In another alternative embodiment, the venetian blinds of the upper outer layer 13 of the curtain panel 11 are electrically controlled to open. The upper outer layer 13 of the curtain panel 11 is connected to the housing 3 via a drive shaft 4, which drives the venetian blinds to slide and rotate along the guide rail 2 to a set angle. The venetian blinds are fixed to the frame of the curtain panel 11 by hinges. The motor is linked to the venetian shaft, and during operation, the motor is triggered to rotate forward and backward by the control switch 5 button, thereby opening or closing the venetian blinds. The control circuit is integrated into the junction box 6 inside the housing 3 and connected to an external power source via wires. By controlling the opening angle of the movable venetian blinds 13 by the motor, the ventilation rate can be flexibly adjusted according to the heat dissipation requirements of the transformer room. Under high-temperature conditions, the venetian blinds are fully open to maximize ventilation and heat dissipation; during strong winds or heavy rain, the venetian blinds are closed and basic ventilation is maintained through the inner soft steel wire mesh 12.
[0049] In one optional embodiment of this utility model, the soft steel wire mesh 12 of the inner layer of the curtain panel 11 of the roller shutter door 1 and the upper outer layer of movable venetian blinds 13 are synchronously controlled to be pulled up and down. The soft steel wire mesh 12 of the inner layer of the curtain panel 11 and the movable venetian blinds 13 of the outer layer are pulled up and down through a drive shaft 4. The drive shaft 4 drives the curtain panel 11 to rise and fall as a whole. During the rise and fall, it slides along the guide rails 2 on both sides. The expansion bolts 8 pass through the guide rails 2 and are directly embedded into the wall to fix the guide rails 2 to the wall. The movable venetian blinds 13 of the outer layer are connected to the frame of the curtain panel 11 through hinges. Its opening and closing angle is independently controlled by an auxiliary motor, but the rising and falling action is synchronized with the soft steel wire mesh 12 of the inner layer. The drive shafts of the venetian blinds and the soft steel wire mesh 12 are installed coaxially. The rising and falling trajectories of the movable venetian blinds 13 of the outer layer and the soft steel wire mesh 12 of the inner layer are guided by the guide rails to ensure synchronization. The control circuit is integrated into the outlet box 6 in the housing 3, and the rising and falling function is operated uniformly through the control switch 5. By using the same motor to drive the inner soft steel wire mesh 12 and the outer movable venetian blind layer 13 to rise and fall synchronously, the structural complexity can be simplified and energy consumption reduced, while maintaining the independent adjustment capability of the outer movable venetian blind layer 13 to open and close.
[0050] In an optional example of this implementation, the soft wire mesh 12 and the movable venetian blind layer 13 are simultaneously connected to a guide rail to ensure synchronization. This guide rail needs to be flexibly connected and retractable into the housing 3.
[0051] The detailed explanations of the above embodiments are intended only to explain the present invention so as to facilitate a better understanding of the present invention. However, these descriptions should not be construed as limiting the present invention for any reason. In particular, the various features described in different embodiments can be arbitrarily combined with each other to form other embodiments. Unless there is an explicit description to the contrary, these features should be understood to be applicable to any embodiment, and not limited to the described embodiments.
