Description

Technical Field

[0001] This utility model relates to a door, and more particularly to an automatic fireproof door for pipe gallery inspection. Background Technology

[0002] In underground spaces where equipment is installed, the biggest concern is damage to the machinery (such as data centers). This necessitates manual inspections of these underground spaces to eliminate potential safety hazards. However, manual inspections are cumbersome due to the limited space, time-consuming, and infrequent, leading to safety issues. Current practices utilize inspection robots. To ensure the safety of underground equipment, these spaces are often partitioned to minimize damage in the event of a fire. However, when partitioning underground spaces, the inspection robots require support and guidance along utility tunnel tracks. Traditional fire-resistant partition doors cannot be closed, yet to pass inspection, operable fire-resistant doors must be installed. This creates a conflict between the robot's movement via utility tunnel tracks and fire-resistant partitions (e.g., Figure 5 As shown in the figure, in order to solve the above problems, there is an urgent need in the market for a fire door that can allow inspection robots to pass through smoothly, safely and automatically, and also provide fire protection for the pipe gallery. Utility Model Content

[0003] This utility model aims to overcome the shortcomings of the prior art by providing an automatic fireproof door for pipe gallery inspection that allows inspection robots to pass smoothly, safely, and automatically while also providing fire protection for the pipe gallery. This satisfies the requirements of inspection robots to pass smoothly, safely, and automatically while also providing fire protection for the pipe gallery.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: This automatic fireproof door for pipe gallery inspection includes a door frame, with a left door and a right door made of fireproof material hinged to the door frame. A pair of electric door closers are installed on the door frame to open and close the left and right doors respectively. The left and right doors have openings for the passage of a track. A control circuit board for controlling the opening and closing of the two electric door closers is installed on the side of the electric door closers, and a signal receiver is installed on the control circuit board. Here, the left and right doors serve as fireproof partitions for the pipe gallery; the electric door closers automatically open the left and right doors to allow the inspection robot to pass through, and automatically close the left and right doors after the inspection robot has passed, thus achieving the effect of automatic fireproof partitioning of the pipe gallery; the openings for the pipe gallery track to pass through do not affect the use of the inspection robot (e.g., ...). Figure 4(As shown); The function of the control circuit board and signal receiver here is that when the inspection robot is about to reach the fire door, it sends a signal to the signal receiver, which in turn sends an opening command to the two electric door closers through the control circuit board, thereby opening the left and right doors. After the inspection robot passes through the fire door, it sends another signal to the signal receiver, which in turn sends a closing command to the two electric door closers through the control circuit board, thereby closing the left and right doors to achieve a fireproof isolation effect. The signal receiver here is a product that is already available on the market, and products from companies such as Shanghai Yiwente Electronic Technology Co., Ltd. and Fuzhou Deyi Electronic Technology Co., Ltd. can be selected. The gap between the left and right doors is to prevent interference when the left and right doors are opened or closed, so that they can be opened or closed without failure.

[0005] Further improvements include the installation of a cover on the door frame to enclose the two electric door closers. The purpose of this cover is to provide dust and impact protection for the electric door closers, control circuit boards, and signal receivers.

[0006] Further improvements include the installation of a power switch and a data signal connector on the housing. The power switch allows manual operation of the automatic fire door to be stopped when lubrication or maintenance is needed, preventing the fire door from automatically opening upon receiving a signal from the inspection robot and potentially injuring maintenance personnel. The data signal connector allows connection to a data cable to transmit signals to the backend data center, enabling the collection of fire door opening and closing data. This data allows for the determination of the inspection robot's inspection frequency and also provides information on whether the automatic fire door is functioning correctly.

[0007] Further improvements include connecting the electric door closer to the left door and the electric door closer to the right door via rocker arms. The rocker arms enable rapid opening and closing of the left and right doors, achieving a rapid response and allowing the inspection robot to pass quickly and close the doors promptly, thus contributing to the fire prevention effect of the utility tunnel.

[0008] The beneficial effects of this utility model are:

[0009] 1) Fire prevention operations can be carried out in the pipe gallery space where equipment is installed through the left and right doors, reducing losses;

[0010] 2) The track opening allows the utility tunnel track to be installed, enabling inspection robots to perform inspections along the track.

[0011] 3) The electric door closer, control circuit board, and signal receiver can receive signals sent by the inspection robot and send operation signals to the electric door closer through the control circuit board, thereby enabling the left and right doors to open and close automatically.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Referring to the attached diagram: This type of automatic fireproof door for pipe gallery inspection includes a door frame 1, with a left door 2 and a right door 3 made of fireproof material hinged to the door frame 1. A pair of electric door closers 4 are installed on the door frame 1 to open and close the left door 2 and the right door 3 respectively. The left door 2 and the right door 3 have track openings 5 ​​for the passage of the track. A control circuit board 6 for controlling the opening and closing of the two electric door closers 4 is provided on the side of the electric door closers 4. A signal receiver 7 is installed on the control circuit board 6.

[0020] A cover 8 is installed on the door frame 1 to cover the two electric door closers 4.

[0021] A power switch 9 and a data signal connector 10 are installed on the housing 8.

[0022] The electric door closer 4 is connected to the left door 2 and the electric door closer 4 is connected to the right door 3 via rocker arms 11.

[0023] The working principle of this utility model is as follows: Equipment cabinet units are arranged sequentially along the pipe gallery. Each pipe gallery is divided into N areas, isolated by N automatic fire doors. Each fire door has a unique node address and communicates with the main control device via an RS485 bus. When the inspection robot moves along the pipe gallery from one point (point A) to another point (point B) and reads the required data, it uploads the data to the main controller via a wireless LAN for data management. The entire process requires no manual intervention. The workflow is as follows: When the inspection command is issued by the main controller in the computer room to the inspection robot (not shown in the figure) via a wireless LAN, the inspection robot starts from the starting position of pipe gallery track 12. When it reaches the automatic fire door, it uses wireless near-field communication (NFC) access control for identification. The NFC uploads the authentication data to the main controller for further processing. For legitimacy verification, the main controller sends a signal to the inspection robot via the RS485 bus, which is received by the signal receiver 7. The control circuit board 6 then controls the two electric door closers 4, causing the rocker arm 11 to automatically and quickly open the left door 2 and right door 3, allowing the inspection robot to enter the designated area. Upon receiving data collection and completion signals from the inspection robot, the main controller sends a command to the robot, which then sends a signal to the signal receiver 7. The control circuit board 6 then controls the two electric door closers 4, causing the rocker arm 11 to automatically and quickly close the left door 2 and right door 3, effectively closing the area with automatic fire doors. This operation automatically manages all units on the equipment cabinet of the entire pipe gallery, making it particularly suitable for managing equipment in harsh environments and worthy of widespread application.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
