Technical Field

[0001] The invention relates to the technical field of fireproof doors, and in particular to an active steel-wood thermal insulation fireproof door. Background Art

[0002] Active steel-wood insulated fire door is a composite fire door that combines steel and wood. It not only has good fire resistance, but also has certain intelligent or automated functions. This type of fire door adds automatic closing system, monitoring alarm and other features on the basis of traditional fire doors to improve safety and ease of use. The frame of this fire door is usually made of solid steel to ensure structural strength. The interior is filled with high-efficiency insulation materials such as rock wool or glass fiber to provide good insulation. The outer surface is decorated with natural wood or other wood composite materials to maintain beauty while enhancing fire resistance.

[0003] Existing fire doors are mostly provided with observation windows, so that firefighters can observe the fire through the fire doors. However, when a fire occurs, the glass will be smoked by the flames for a long time and its light transmittance will be affected. At this time, firefighters will not be able to observe the fire normally through the observation window. Summary of the invention

[0004] In order to overcome the shortcomings mentioned in the above background technology, the present invention provides an active steel-wood thermal insulation fireproof door.

[0005] The technical solution is as follows: An active steel-wood thermal insulation fire door, including: Door panels; Glass, the door panel is provided with an observation window, and the glass is arranged in the observation window; There are two shielding plates, both of which are slidably connected to the door panel, and are used to prevent the glass from being burned by fire. The door panel is slidably connected to a connecting piece, and the two shielding plates are fixedly connected to the connecting piece; The first fixed shell is fixedly connected in the door panel. The first fixed shell is slidably connected to a first sliding rod, and the first sliding rod is fixedly connected to the connecting member.

[0006] Furthermore, the first fixed shell is filled with thermal expansion gas for monitoring the temperature of the door panel, and a tension spring is provided between the first fixed shell and the first sliding rod.

[0007] Furthermore, it also includes: A heat conducting member is provided through the door panel and is fixedly connected to the first fixing shell.

[0008] Furthermore, it also includes: A limiting column is slidably connected to the door panel, and the connecting piece is provided with a groove that cooperates with the limiting column; A sliding plate, spline-connected to the door plate, a first spring being arranged between the limiting column and the sliding plate; The adjusting assembly is arranged on the door panel and is used for adjusting the position of the sliding plate to change the initial compression amount of the first spring.

[0009] Furthermore, the adjustment component includes: A threaded rod, rotatably connected to the door panel, the threaded rod being threadably engaged with the sliding panel; The rotating plate is fixedly connected to the threaded rod, and the door panel is slidably connected to a second sliding rod, and the second sliding rod is transmission-matched with the rotating plate.

[0010] Furthermore, the shielding plate is fixedly connected with a cleaning strip, and the cleaning strip is slidably matched with the glass.

[0011] Furthermore, it also includes: There are two water spray pipes, which are respectively fixed to the two sides of the door panel, and the water spray pipes are provided with a plurality of through holes; There are two regulating shells, which are respectively fixed to the two sides of the door plate, and the two regulating shells are respectively connected to the adjacent water spray pipes, and the regulating shells are connected to the water supply device; There are two control components, both of which are arranged on the door panel. The control components are used to change the water flow sprayed from the adjacent water spray pipes according to the temperature near the door panel.

[0012] Furthermore, the control component includes: An adjustment plate, slidably connected to the adjustment shell; The second fixed shell is fixed to the door panel, and the second fixed shell is slidably connected to a sliding member fixed to the adjacent adjustment plate. A second spring is arranged between the side of the sliding member away from the adjacent adjustment shell and the second fixed shell, and thermal expansion gas is injected into the second fixed shell.

[0013] Furthermore, the water spray pipe is rotatably connected to a blocking shell, a torsion spring is provided between the blocking shell and the adjacent water spray pipe, the blocking shell is located above the glass, and the blocking shell is sealed and cooperated with the adjacent through holes on the water spray pipe.

[0014] Furthermore, it also includes: There are two thin ropes, which are respectively wound around the adjacent blocking shells, and the thin ropes are fixedly connected to the adjacent shielding plates; There are two guide members, which are respectively fixed to the two sides of the door panel, and the thin rope passes through the adjacent guide members.

[0015] The beneficial effects of the present invention are as follows: the present invention blocks both sides of the glass on the door panel by two shielding plates, so that the glass will not be smoked by the flames for a long time and its light transmittance will be affected in the event of a fire, so as to avoid firefighters being unable to observe the fire through the observation window. The shielding of the shielding plates can prevent the glass from being damaged due to being smoked by the flames for a long time, thereby reducing the economic losses caused by the fire.

[0016] By making the shielding plate not block the glass under normal circumstances, people passing by the device can observe the situation behind the door easily, avoiding injuries caused by people opening doors on both sides of the device at the same time. When a fire occurs near the door panel, the hot expanding gas in the first fixed shell expands, thereby driving the shielding plate to block the glass, so as to achieve the effect of automatically blocking the glass.

[0017] When the door panel is smoked by flames, the water spray pipe sprays water to the door panel, thereby reducing the temperature of the door panel, extending the fire-blocking time of the door panel, and preventing people from being scalded due to the overhigh temperature of the device when escaping through the device. At the same time, the local through holes on the water spray pipe are blocked by the blocking shell to ensure a good line of sight when observing through the glass. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] An active steel-wood thermal insulation fire door, such as Figure 1-Figure 8 As shown, it includes: a door panel 1; a glass 2, the door panel 1 is provided with an observation window, and the glass 2 is arranged in the observation window; there are two baffles 3, both of which are slidably connected to the door panel 1, for preventing the glass 2 from being smoked by fire, the door panel 1 is slidably connected to a connecting member 4, and the two baffles 3 are fixedly connected to the connecting member 4; a first fixed shell 5, fixed in the door panel 1, the first fixed shell 5 is slidably connected to a first sliding rod 6, and the first sliding rod 6 is fixedly connected to the connecting member 4.

[0022] In the above scheme, the glass 2 is shielded to prevent the glass 2 from being smoked by flames and causing a decrease in light transmittance. The door panel 1 is a mixed material of steel and wood. The door panel 1 is installed on the door frame and connected to the active door closer on the door frame. When a fire occurs, the smoke sensor senses and uploads the fire information, and then the corresponding active door closer closes the door panel 1 to prevent the fire from spreading. The glass 2 can be tempered glass or fire-resistant glass such as borosilicate glass. The shielding plates 3 are located on both sides of the glass 2 to adapt to the fire on both sides of the door panel 1. The shielding plates 3 are made of heat-insulating material to reduce the temperature transmitted to the glass 2. The connecting member 4 is a quadrangular prism-shaped shell. The connecting member 4 is also made of heat-insulating material to improve the heat-insulating performance of the device. The first fixed shell 5 is made of heat-conductive material to facilitate monitoring the temperature near the door panel 1 and determine whether the fire spreads to the vicinity of the door panel 1.

[0023] Furthermore, the first fixed shell 5 is filled with thermal expansion gas for monitoring the temperature of the door panel 1 , and a tension spring is provided between the first fixed shell 5 and the first sliding rod 6 .

[0024] In the above scheme, the temperature of the door panel 1 is monitored so that the first sliding rod 6 moves when the temperature of the door panel 1 reaches a certain level. When the temperature of the door panel 1 increases, the door panel 1 transfers heat to the first fixed shell 5, and the hot expanding gas in the first fixed shell 5 expands and pushes the first sliding rod 6 to move, and the first sliding rod 6 stretches the adjacent tension spring when it moves.

[0025] Furthermore, the door panel 1 further includes a heat conducting member 7 , which is disposed through the door panel 1 and is fixedly connected to the first fixing shell 5 .

[0026] In the above scheme, the temperature of the environment near the door panel 1 is more easily transferred to the thermally expanding gas in the first fixed shell 5. When the temperature of the environment near the door panel 1 increases, the temperature is transferred to the first fixed shell 5 through the heat conducting member 7.

[0027] Furthermore, it also includes: a limit column 8, which is slidably connected to the door panel 1, and the connecting member 4 is provided with a groove that cooperates with the limit column 8; a sliding plate 9, which is splined to the door panel 1, and a first spring is provided between the limit column 8 and the sliding plate 9; an adjustment component, which is provided on the door panel 1, and is used to adjust the position of the sliding plate 9 to change the initial compression amount of the first spring.

[0028] In the above scheme, the purpose is to make the connector 4 move when the ambient temperature is about to exceed the maximum bearing capacity of the glass 2. The limit column 8 is composed of a hemisphere and a cylinder. The cylindrical part of the limit column 8 is slidably connected to the door panel 1. The groove on the connector 4 is hemispherical and matches the hemispherical part on the limit column 8. When the limit column 8 is inserted into the groove on the connector 4, the connector 4 will be resisted by the limit column 8 when moving in a horizontal plane perpendicular to the axis of the limit column 8. The first spring between the limit column 8 and the sliding plate 9 is initially in a compressed state, which is used to provide the limit column 8 with a force to limit the connector 4. When the position of the sliding plate 9 changes, the compression amount of the first spring changes, and the pressure of the first spring on the limit column 8 changes, thereby changing the resistance of the limit column 8 to the sliding plate 9, so that the timing of triggering the connector 4 can be changed according to the heat resistance of the glass 2.

[0029] Furthermore, the adjustment component includes: a threaded rod 10, which is rotatably connected to the door panel 1 and threadedly engaged with the sliding plate 9; a rotating plate 11, which is fixed to the threaded rod 10 and slidably connected to the door panel 1 and a second sliding rod 12, which is transmission-engaged with the rotating plate 11.

[0030] In the above scheme, the position of the sliding plate 9 is adjusted to change the initial compression of the first spring. The lower part of the threaded rod 10 is provided with threads, and the upper part of the threaded rod 10 is rotatably connected to the door panel 1. When the threaded rod 10 rotates, the sliding plate 9 cannot rotate, so the threaded rod 10 will drive the sliding plate 9 to slide up and down. When the sliding plate 9 moves downward, the initial compression of the first spring will increase to increase the pressure of the limit column 8 on the connecting member 4. When the sliding plate 9 moves upward, the initial compression of the first spring will decrease to reduce the pressure of the limit column 8 on the connecting member 4. The transmission method between the rotating plate 11 and the second sliding rod 12 can be friction transmission (such as setting friction materials on the surfaces of the rotating plate 11 and the second sliding rod 12) or can be gear rack transmission or other transmission methods.

[0031] Furthermore, the shielding plate 3 is fixedly connected with a cleaning strip 31 , and the cleaning strip 31 is slidably matched with the glass 2 .

[0032] In the above scheme, the purpose is to clean the impurities attached to the glass 2 to ensure the light transmittance of the glass 2. The cleaning strip 31 is made of rubber material to prevent the cleaning strip 31 from scratching the glass 2 and ensure that the cleaning strip 31 can clean the impurities on the glass 2.

[0033] Working process: when a fire occurs in the area where the device is installed, the smoke sensor at the fire location detects the occurrence of the fire and transmits information to the nearby door closer to close the door panel 1 of the device. When the flame does not burn near the door panel 1, the shielding plate 3 does not block the glass 2, so that the firefighters can directly observe the fire on the other side of the door panel 1 through the glass 2 after arriving. When the fire spreads to the vicinity of the door panel 1, the ambient temperature near the door panel 1 increases significantly, and the heat is transferred to the first fixed shell 5 through the heat conductive member 7, and then the hot expansion gas in the first fixed shell 5 expands. After the hot expansion gas expands, it pushes the first sliding rod 6 to move and stretches the tension spring. The first sliding rod 6 is The rod 6 drives the connecting member 4 to move, and the connecting member 4 drives the two shielding plates 3 to move, so that the two shielding plates 3 cover the glass 2 to prevent smoke and dust from adhering to the surface of the glass 2. At this time, if the firefighters need to observe the fire through the glass 2, they only need to move the shielding plates 3. After the fire is extinguished, the ambient temperature near the door panel 1 drops, and the temperature is transmitted to the thermal expansion gas in the first fixed shell 5, causing the thermal expansion gas to contract. At this time, the first sliding rod 6 is reset under the action of the tension spring, and the two shielding plates 3 are reset through the connecting member 4. When the shielding plate 3 moves, it drives the adjacent cleaning strip 31 to move, so that the cleaning strip 31 scrapes off the surface impurities of the glass 2.

[0034] Furthermore, it also includes: two water spray pipes 13, which are respectively fixed to the two sides of the door panel 1, and the water spray pipes 13 are provided with a plurality of through holes; two adjusting shells 14, which are respectively fixed to the two sides of the door panel 1, and the two adjusting shells 14 are respectively connected to the adjacent water spray pipes 13, and the adjusting shells 14 are connected to the water supply device; there are two control components, both of which are arranged on the door panel 1, and the control components are used to change the water flow sprayed from the adjacent water spray pipes 13 according to the temperature near the door panel 1.

[0035] In the above scheme, the door panel 1 is intended to be cooled to increase the fireproof duration of the door panel 1. The water spray pipe 13 is located at the upper part of the door panel 1, and the through holes on the water spray pipe 13 are evenly distributed so that the water flow is evenly sprinkled on the surface of the door panel 1 to evenly cool the door panel 1. The through holes on the water spray pipe 13 are located at the lower part of the water spray pipe 13, close to the side of the door panel 1, so that the water flow sprays out from the through holes, sprays on the upper side of the door panel 1, and flows down along the surface of the door panel 1. The water supply device is an existing device, which can be a fire hose, and will not be described in detail here. When the ambient temperature near the door panel 1 is high, the control component increases the amount of water entering the water spray pipe 13, thereby increasing the amount of water sprayed onto the surface of the door panel 1 to ensure that there is enough water to cool the door panel 1. When the ambient temperature near the door panel 1 is low, the control component reduces the amount of water entering the water spray pipe 13, thereby reducing the amount of water sprayed onto the surface of the door panel 1, and reducing the water consumption while achieving the cooling effect on the door panel 1.

[0036] Furthermore, the control component includes: an adjustment plate 15, which is slidably connected to the adjustment shell 14; a second fixed shell 16, which is fixed to the door panel 1, and the second fixed shell 16 is slidably connected to a sliding member 17 fixed to an adjacent adjustment plate 15, and a second spring is arranged between the side of the sliding member 17 away from the adjacent adjustment shell 14 and the second fixed shell 16, and the second fixed shell 16 is filled with thermal expansion gas.

[0037] In the above scheme, the size of the water flow sprayed from the water spray pipe 13 is controlled according to the ambient temperature. When the adjustment plate 15 moves downward, the communication area of ​​the adjustment shell 14 increases, and the amount of water entering the water spray pipe 13 per unit time increases, thereby increasing the amount of water sprayed from the water spray pipe 13. When the adjustment plate 15 moves upward, the communication area of ​​the adjustment shell 14 decreases, and the amount of water entering the water spray pipe 13 per unit time decreases, thereby reducing the amount of water sprayed from the water spray pipe 13. The second fixed shell 16 is made of a heat-conducting material so that the thermal expansion gas can monitor the ambient temperature more accurately. The sliding member 17 is composed of a round rod and a disc. A second spring is arranged between the lower side of the disc portion of the sliding member 17 and the second fixed shell 16. Thermal expansion gas is injected between the upper side of the disc portion of the sliding member 17 and the second fixed shell 16. When the temperature rises, the thermal expansion gas expands and pushes the sliding member 17 to move. The second spring is initially in a compressed state, so that the thermal expansion gas in the second fixed shell 16 can push the sliding member 17 to move only after reaching a certain temperature.

[0038] Furthermore, the water spray pipe 13 is rotatably connected to a blocking shell 18 , a torsion spring is provided between the blocking shell 18 and the adjacent water spray pipe 13 , the blocking shell 18 is located above the glass 2 , and the blocking shell 18 cooperates with the adjacent through holes on the water spray pipe 13 to block the blocking shell.

[0039] In the above scheme, the through hole on the water spray pipe 13 located above the glass 2 is blocked so that the sight of the firefighters will not be blocked by the water flow when observing the fire through the glass 2. The blocking shell 18 is a through cylindrical shape, and is provided with a connecting hole with an area larger than the through hole on the water spray pipe 13. When the connecting hole is aligned with the through hole, the water flows out from the through hole. When the two are not aligned, the water cannot flow out from the blocked through hole.

[0040] Furthermore, it also includes: two thin ropes 19, which are respectively wound around adjacent blocking shells 18, and the thin ropes 19 are fixed to adjacent shielding plates 3; two guide members 20, which are respectively fixed to both sides of the door panel 1, and the thin ropes 19 pass through adjacent guide members 20.

[0041] In the above scheme, the blocking shell 18 is intended to move synchronously with the adjacent shielding plate 3. When the string 19 is pulled, the string 19 drives the adjacent blocking shell 18 to rotate, so that the blocking shell 18 releases the blocking of the through hole on the adjacent water spray pipe 13.

[0042] Working process: When the ambient temperature near the door panel 1 is too high, the hot expanding gas in the second fixed shell 16 expands and pushes the sliding member 17 to move downward, and the sliding member 17 drives the adjusting plate 15 to move, so that the water flows through the adjusting shell 14 into the water spray pipe 13 and sprays to the surface of the door panel 1 to cool it down. At the same time, the hot expanding gas in the first fixed shell 5 expands and drives the shielding plate 3 to shield the glass 2. When the shielding plate 3 moves, it pulls the string 19, and the string 19 pulls the blocking shell 18 to rotate. When the blocking shell 18 rotates, the adjacent torsion spring accumulates force. At this time, the connecting hole on the blocking shell 18 is connected to the corresponding hole on the shielding plate 3. The adjacent through holes are aligned, and water flows out from them. When the firefighters need to observe, they move the shielding plate 3 to release the shielding plate 3 from blocking the glass 2. At the same time, the torsion spring drives the blocking shell 18 to reset. At this time, the connecting hole on the blocking shell 18 is misaligned with the adjacent through hole on the shielding plate 3, and the through hole on the shielding plate 3 above the glass 2 is blocked to prevent the water flow above the glass 2 from flowing along the door panel 1 to the observation window to form a water curtain that affects observation. When the fire is subsided, the thermal expansion gas in the second fixed shell 16 contracts. At this time, the sliding member 17 is reset under the action of the second spring, and the drive adjustment plate 15 is reset.

[0043] The present invention provides a thought and method. There are many methods and ways to implement the technical solution. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
