Description

Technical Field

[0001] This utility model relates to data center computer rooms, specifically to a combined expandable, automatically resetable movable skylight for enclosed cold aisles in data center computer rooms. Background Technology

[0002] With the rapid development of the data center industry, the density of IT server racks is also continuously increasing, thus placing increasingly stringent requirements on airflow organization within the server room. The current common practice for airflow organization in IT server rooms is to divide them into hot and cold aisles. Major data center operators now use enclosed cold aisles for equipment cooling, ensuring uniform heat dissipation, maximizing the utilization of cool air, and achieving good energy-saving intelligent control.

[0003] In the event of a fire, existing enclosed cold aisle skylights can be reset manually or automatically via an electric control mechanism. Manual reset is labor-intensive, time-consuming, and inefficient; automatic reset requires each skylight to be equipped with an electric control mechanism, which results in high construction costs and a high failure rate. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a combined expandable automatic reset movable sunroof, which should be easy to operate and low in cost.

[0005] The technical solution of this utility model is:

[0006] A modular, expandable, automatically resetting sunroof is characterized by comprising several sunroof units arranged horizontally, a drive mechanism for closing all sunroof units, a magnetic attraction mechanism for locking all sunroof units, and a controller; each sunroof unit includes a frame with a window.

[0007] The window is rotatably positioned on the frame via a pivot, and the pivots of each skylight unit are parallel to each other.

[0008] The drive mechanism includes an electric push rod, a connecting rail slidably positioned on the frame and connected to the piston rod of the electric push rod, triangular pressure blocks set on the frame of each window, and several pulleys rotatably positioned on the connecting rail for pushing each triangular pressure block respectively.

[0009] The magnetic attraction mechanism includes an electromagnet mounted on the frame of each skylight unit and an iron block mounted on the window frame of each skylight unit.

[0010] The electromagnet is mounted on the frame of each skylight unit near the bottom edge of the window; the pivot is located between the triangular pressure block and the electromagnet; the center of gravity of the window is located between the pivot and the electromagnet.

[0011] The connecting rail is perpendicular to the axis of rotation.

[0012] The frame is also equipped with a limit switch for detecting the position of the sunroof.

[0013] The controller is electrically connected to an electric push rod, an electromagnet, and a limit switch.

[0014] The beneficial effects of this utility model are:

[0015] This invention successfully solves the problems of traditional operable skylights, such as the labor-intensive and time-consuming manual reset being inefficient, and the one-to-one automatic reset being limited to one-to-one, high construction costs, and complex design. It has the advantages of low construction costs, low maintenance costs, high work efficiency, and the ability to achieve intelligent operation and management. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0026] like Figure 1As shown, the modular expandable automatic reset sunroof includes a sunroof unit, a drive mechanism, a magnetic attraction mechanism, and a controller (omitted in the figure).

[0027] The skylight units are arranged horizontally. Figure 4 The horizontal direction is considered as transverse and the vertical direction as longitudinal. The number of skylight units depends on the needs, and usually 1-4 skylight units are set. The figure shows a total of 4 skylight units.

[0028] The drive mechanism is used to close all sunroof units, the magnetic mechanism is used to lock the sunroof units to keep them closed, and the controller is electrically connected to the drive mechanism and the magnetic mechanism.

[0029] The skylight unit includes a frame 1 with a window 2. The frame consists of two horizontal beams 1-1 and two vertical beams 1-2. The window is rotatably positioned on the horizontal beams of the frame via a pivot 2-1. The frames of all skylight units are connected as one unit.

[0030] When the window is open, the top edge 2-2 of the window frame is above the frame, and the bottom edge 2-3 of the window frame is below the frame. When the skylight is closed, the top edge of the window frame drops to be flush with the frame, and the bottom edge of the window frame rises to be flush with the frame.

[0031] The drive mechanism includes an electric push rod 3, a connecting rail 4, a triangular pressure block 5, and a pulley 6. The electric push rod is fixed to the frame beam of one of the sunroof units. The connecting rail is parallel to the beam and slidably positioned on the same side of the beam via guides 1-3. One end of the connecting rail is fixed to the piston rod of the electric push rod. The electric push rod can push the connecting rail to move in a direction parallel to the beam.

[0032] like Figure 6 As shown, several pulleys are rotatably positioned on the side of the connecting rail. The number of pulleys is the same as the number of skylight units. Each skylight unit has one pulley on its side, and each skylight unit has a triangular pressure block on the top surface of its window frame. The inclined surface of the triangular pressure block faces the pulley corresponding to that skylight unit. Driven by an electric push rod, the pulleys push the triangular pressure block, causing the window to rotate.

[0033] The magnetic attraction structure includes an electromagnet 7 mounted on each skylight unit. The electromagnets are mounted on the longitudinal beams of the frame. Figure 7 As shown, the electromagnet is mounted on the longitudinal beam near the bottom edge of the window frame, and an iron block (omitted in the figure) is also provided at the bottom edge of the window frame to ensure that the electromagnet can hold the skylight.

[0034] The skylight unit is also equipped with limit switches 8 for detecting whether the window is closed. The limit switches are installed on the longitudinal beams of the frame, and one limit switch is installed on the side of each electromagnet.

[0035] For each skylight unit, the pivot is located between the triangular pressure block and the electromagnet, and the center of gravity of the window is located between the pivot and the electromagnet. The window can open naturally under the action of gravity (along...). Figure 3 (rotating clockwise), or the pulley closes the window by pushing the triangular pressure block (along the clockwise direction). Figure 3 (rotating counterclockwise).

[0036] The skylight unit's frame is also equipped with a limiting component (omitted in the figure) to control the window's rotation angle.

[0037] The controller is electrically connected to an electric push rod, an electromagnet, and a limit switch.

[0038] All components of this utility model are existing technologies.

[0039] The working principle of this utility model is as follows:

[0040] 1. Closing a window: The controller sends a signal, the electric push rod starts, the track moves forward, and the pulleys apply a pushing force to the triangular pressure blocks of each window to close the window;

[0041] 2. When all windows are completely closed, the limit switch is triggered, the controller sends a signal, the electromagnet starts and thus generates attraction, the windows remain closed, and the electric push rod drives the rail to move backward to complete the reset.

[0042] 3. In case of emergencies such as fire, the controller sends a signal, the electromagnet is de-energized, and all windows rotate rapidly under gravity to open. Figure 1 As shown;

[0043] 4. After the alarm is cleared, all windows will close (return to steps 1-2).

[0044] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
