Cable bridge fireproof partition and emergency evacuation indicating device

Abstract

The utility model provides a cable bridge fireproof partition and emergency evacuation indicating device, which belongs to the technical field of cable bridges and comprises a bridge, a connecting block, a placing frame, a cover plate, an emergency evacuation indicating board, a connecting rod, a bearing seat, a fastening bolt, a hinge, a partition plate and a temperature sensing glass ball. When the temperature sensing glass ball encounters high temperature, the sealing liquid in the glass ball encounters high-temperature gas, expands along with the rise of the temperature, and decomposes the ball body into small fragments at the high temperature, so that the partition plate suspended at the lower end falls down, and therefore, the temperature sensing glass ball is prevented from falling off. The partition plate can turn over and rotate at the lower end of the placement frame through the hinge to block the inner cavity of the bridge frame, so that the partition plate plays a role in isolation when a fire occurs, prevents fire from spreading and prevents flames and smoke from spreading to other areas through a bridge frame system, and is beneficial to control the fire range, prolong the evacuation time and improve the safety.

Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a cable bridge fireproof partition and emergency evacuation indicating device. Background Art

[0002] Cable tray systems play an important role in buildings, supporting and protecting various types of cables such as power, communication, and data. However, due to the large number of cables in the cable tray system, once a fire occurs, it may cause serious damage to the entire building. Therefore, it is crucial to carry out effective fire protection design;

[0003] It has been found in actual use that the existing cable trays have the following deficiencies:

[0004] Although existing cable trays are made of flame-retardant materials to ensure that they are not easy to burn in the event of a fire, the cable trays are interconnected as a whole. When a fire occurs, flames and smoke can easily spread to other areas through the cable tray system, causing the fire to expand and affecting the evacuation time.

[0005] In addition, the existing cable tray structure is relatively simple and does not have the function of evacuation indication in the event of an emergency, which affects the safety of the overall building layout;

[0006] Therefore, the present application provides a cable tray fire partition and emergency evacuation indicator device to meet the needs. Utility Model Content

[0007] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a cable tray fireproof partition and emergency evacuation indicating device.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] A cable bridge fireproof partition and emergency evacuation indication device, comprising: a bridge, a connecting block, a placement rack, a cover plate, an emergency evacuation sign, a connecting rod, a supporting seat, fastening bolts, a hinge, a partition plate and a temperature-sensitive glass ball, wherein a connecting block is installed at the middle of the bottom of the bridge, a placement rack is installed at the inner upper end of the bridge, a cover plate is installed on the inner side of the placement rack, an emergency evacuation sign is installed at the bottom of the bridge, a connecting rod is installed at the upper end of the emergency evacuation sign, a supporting seat is installed at the upper end of the connecting rod, fastening bolts are installed on the side of the connecting block, a partition plate is installed at the bottom of the placement rack through a hinge, and a temperature-sensitive glass ball is installed on the surface of the partition plate.

[0011] Preferably, hinges are installed on both left and right sides of the partition board, and the partition board is movably connected to the placement rack through the hinges.

[0012] Preferably, the partition plate is placed horizontally, and the partition plate is parallel to the cover plate.

[0013] Preferably, the temperature-sensitive glass ball is arranged vertically, and the other end of the temperature-sensitive glass ball is fixed to the bottom of the placement rack.

[0014] Preferably, the partition plate is in a "concave" shape, and the partition plate fits in with the inner cavity of the bridge frame.

[0015] Preferably, a circular cavity is provided in the middle of the connecting block, and a circular ring-shaped limiting groove is provided in the circular cavity of the connecting block.

[0016] Preferably, the supporting seat is in a "T"-shaped frustum, the supporting seat is embedded in the interior of the connecting block, and the emergency evacuation sign is fixed to the connecting block via the supporting seat.

[0017] Preferably, the fastening bolts extend transversely through the connecting block and inwardly to the lower end of the side surface of the supporting seat, and a nut is screwed into the outer end of the fastening bolts.

[0018] Compared with the prior art, the utility model has at least the following beneficial effects:

[0019] 1. When a fire occurs, the fire scene heats up, and the metal bridge is heated up. The temperature is transmitted to the temperature-sensitive glass ball. When the temperature-sensitive glass ball encounters high temperature, the sealing liquid in the glass ball encounters high-temperature gas and expands as the temperature rises. Under high temperature, the sphere is decomposed into small pieces, causing the partition board hanging at the lower end to fall down. The partition board can be flipped and rotated at the lower end of the placement rack through the hinge, blocking the inner cavity of the bridge frame, playing an isolation role when a fire occurs, preventing the fire from spreading, and preventing the flame and smoke from spreading to other areas through the bridge system, which helps to control the scope of the fire, extend the evacuation time, and improve safety;

[0020] 2. An emergency evacuation sign is installed at the lower end of the bridge. During installation, the emergency evacuation sign can be flexibly rotated to adjust the position of the emergency evacuation sign at the lower end of the bridge. The side of the supporting seat can be pressed against by tightening the bolts, and the supporting seat can be locked on the inner side of the connecting block to fix the position of the emergency evacuation sign. The emergency evacuation sign hung at the lower end of the bridge can indicate the direction, which is convenient for guiding the escape route and evacuating personnel.
