Description

Technical Field

[0001] This utility model relates to the field of fire protection facilities technology, specifically a fire baffle for building fire protection engineering. Background Technology

[0002] With the development of building technology and the continuous advancement of urban construction, high-rise buildings, large complexes, and densely populated places are increasing, placing higher demands on building fire safety. Passive fire compartmentation is key to controlling the spread of fire, and the application of fire barriers is crucial. However, traditional fire barriers generally suffer from inconvenient adjustment and positioning in practical use. When dealing with sealing needs at different locations and angles, adjustments are time-consuming, labor-intensive, and difficult to fix precisely. Utility Model Content

[0003] The purpose of this utility model is to provide a fire baffle for building fire protection engineering to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fire baffle for building fire protection engineering, comprising a first support, a second support, a shell, and a top plate. Two first support columns are symmetrically welded to the side of the shell. The other end of each first support column is mounted on the first support via a bearing. Two worm gear mounting blocks are welded to the inner wall of the first support. A worm gear is mounted between the two worm gear mounting blocks via a bearing. A worm wheel is welded to the surface of the first support column. The worm wheel meshes with the worm gear. One end of the worm gear passes through the worm gear mounting block and is connected to an eccentric wheel handle. A second support is connected to the side of the first support via a fixing device. Two second support columns are connected to the inner wall of the second support via bearings. A shell is welded between the two second support columns. A bidirectional ratchet and pawl device is installed between the top of one side of the second support and the side wall of the second support column.

[0005] A partition is welded to the inner wall of the outer shell. A heat-insulating and flame-retardant plate is placed on one side of the partition. A main water pipe is installed on the other side of the heat-insulating and flame-retardant plate on the side wall of the outer shell. The main water pipe passes through the inner cavity of the outer shell. An automatic cooling device is installed below the main water pipe and inside the inner cavity of the outer shell.

[0006] Preferably, the top plate has several small holes on one side of its surface, the outer shell has several small holes on one side of its bottom, and the partition has several small holes on one side of its bottom surface. These multiple openings allow for the directional removal of water vapor and water used for cooling.

[0007] Preferably, the fixing device includes a connecting fixing post welded to the side of the first bracket and a connecting fixing tube welded to the side of the second bracket. The connecting fixing post and the connecting fixing tube are nested together. A locking groove is formed on the side wall of the connecting fixing post. A steel ball is installed at an opening in the inner wall of the connecting fixing tube. A spring is connected to the bottom of the hole and the steel ball is engaged and fixed with the locking groove. A steel ball limiting sleeve is installed on the inner wall of the connecting fixing tube. The steel ball limiting sleeve has a hole with a diameter smaller than the diameter of the steel ball at the corresponding position of the steel ball. This achieves "one-insert locking" without the need for auxiliary tools.

[0008] Preferably, the bidirectional ratchet and pawl device includes a pawl mounting block welded to the second bracket and a bidirectional ratchet welded to the side wall of the second support column. A bidirectional pawl is mounted on the side of the pawl mounting block via a rotating shaft, and the bidirectional pawl engages with the bidirectional ratchet. The engagement of the bidirectional pawl with the ratchet achieves bidirectional mechanical locking.

[0009] Preferably, the main water pipe port is connected to either a water pipe connector or a water pipe plug via a threaded connection. This supports multi-device series water supply, expanding the fire protection coverage area.

[0010] Preferably, the automatic cooling device includes a secondary water pipe below the main water pipe, the main water pipe and the secondary water pipe are connected to each other, a number of nozzles are symmetrically installed on the side wall of the secondary water pipe, a water pipe baffle is installed inside the secondary water pipe, a water pipe baffle column is installed below the water pipe baffle, and a thermosensitive liquid glass ball is installed below the water pipe baffle column.

[0011] Preferably, the water pipe block blocks the channel connecting the inner cavity of the main water pipe and the auxiliary water pipe, and the bottom surface of the thermosensitive liquid glass ball is in contact with the inner wall of the auxiliary water pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Precise angle adjustment and locking: The worm gear-gear transmission, combined with the eccentric wheel handle, drives the outer shell to rotate, allowing the fire baffle angle to be finely adjusted with one hand. The two-way ratchet and pawl device enables two-way mechanical locking, which facilitates quick adaptation to the sealing angle of different through-wall pipes, avoids displacement failure due to vibration during a fire, and improves the reliability of fireproof partitions.

[0014] High-temperature intelligent sprinkler cooling: The auxiliary water pipe is equipped with a water pipe baffle structure controlled by a thermosensitive liquid glass ball, which is sealed and leak-proof under normal conditions; when encountering high temperature, the glass block breaks and the baffle instantly releases the seal, ensuring that the sprinkler system is automatically triggered after the fire exceeds the critical temperature, so as to promptly retard the flame and cool down, making up for the delayed response defect of passive fireproof materials.

[0015] Modular quick assembly and disassembly: The connecting fixing column and the nested fixing tube cooperate with each other, and the steel ball automatically locks into the locking groove when inserted, realizing "one-click locking" between the brackets. When disassembling, the bracket can be separated by pulling it, which greatly improves the efficiency of emergency deployment.

[0016] Flexible water system adaptation: The main water pipe port is compatible with threaded water pipe joints or plugs, supporting single-line independent water supply or multi-device series expansion. It can adapt to the on-site fire protection network interface and flexibly add or remove fire-blocking units according to the fire range, enhancing system adaptability. Attached Figure Description

[0030] Please see Figure 1-9 This utility model provides a technical solution: a fire baffle for building fire protection engineering, including a first support 1, a second support 28, a shell 2 and a top plate 3. Two first support columns 9 are symmetrically welded to the side of the shell 2. The other end of the first support column 9 is mounted on the first support 1 through a bearing. Two worm gear mounting blocks 5 are welded to the inner side wall of the first support 1. A worm gear 6 is installed between the two worm gear mounting blocks 5 through a bearing.

A bidirectional ratchet and pawl device is installed between the top of one side of the second support 28 and the side wall of the second support column 29.

[0031] A partition 16 is welded to the inner wall of the outer shell 2. A heat-insulating and flame-retardant plate 17 is placed on one side of the partition 16.

[0032] Furthermore, several small holes are provided on one side of the top plate 3, several small holes are provided on one side of the bottom of the outer shell 2, and several small holes are provided on one side of the bottom surface of the partition plate 16. This facilitates the removal of water vapor and water used for cooling.

[0033] Furthermore, the fixing device includes a connecting fixing post 23 welded to the side of the first bracket 1 and a connecting fixing tube 15 welded to the side of the second bracket 28. The connecting fixing post 23 and the connecting fixing tube 15 are nested together. A locking groove 24 is formed on the side wall of the connecting fixing post 23.

[0038] Working principle:

[0039] Modular rapid assembly: During installation, push the second bracket 28 to align the outer shell 2, and insert the connecting fixing post 23 on the side of the first bracket 1 into the connecting fixing tube 15 on the side of the second bracket 28. During insertion, the steel ball 25 on the inner wall of the fixing tube 15 is pushed into the locking groove 24 by the spring 26, completing the locking. Connect the main water pipe 4 to the water source through threaded connection, connect the main water pipes 4 with water pipe connectors 10, and seal the end of the main water pipe 4 with water pipe plugs 11.

[0040] Angle Adjustment and Positioning: The operator turns the eccentric wheel handle 8 to drive the worm gear 6 to rotate. The worm gear 6 meshes with the worm wheel 7 welded to the side of the first support column 9, causing the outer casing 2 to rotate around the support column 9. After adjusting to the required fireproof tilt angle, the double-sided pawl 13 is turned to the corresponding position. The double-sided pawl 13 engages with the tooth groove of the double-sided ratchet 14 to achieve mechanical locking, ensuring that the fire baffle plate remains stable and does not shift under vibration.

[0041] Fire response and automatic sprinkler system: Under normal conditions, the water pipe baffle 20 is tightly fitted to the inner wall of the auxiliary water pipe 18, and the heat-sensitive liquid glass bulb 22 presses against the water pipe baffle 21, forming a seal. When the fire temperature exceeds the critical value, the heat-sensitive liquid glass bulb 22 ruptures due to heat, the baffle 21 loses its support and moves downward, and the water pipe baffle 20 disengages from the sealed position. Firefighting water flows into the auxiliary water pipe 18 through the main water pipe 4 and is automatically sprayed from the sprinkler head 19 to the high-temperature area. Water vapor is discharged through the perforated array of the top plate 3, and excess water is discharged through the perforated array of the bottom of the partition plate 16 and the outer shell 2.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
