Abstract
Description
Technical Field
[0001] This utility model relates to the field of fire protection technology, specifically a retractable fireproof protection device. Background Technology
[0002] Fire protection measures can effectively prevent the spread of fire in buildings or forests, reduce the probability of fires, ensure the safe evacuation of people, reduce casualties, and help maintain social stability.
[0003] To facilitate daily storage and use, some fireproof protection devices are now designed to be retractable, greatly reducing storage space while also facilitating movement and operation. While fireproof material panels can effectively block flames, as the flame burns for an extended period, the heat at the concentrated point of the flame becomes much greater than that at the edges, and the heat dissipation effect at the center is poor. Therefore, when the flame heat exceeds the melting point of the fireproof material, the fireproof panel may burn through. Thus, a retractable fireproof protection device that can effectively transfer flame heat and extend the service life of the fireproof panel is needed. Utility Model Content
[0004] The purpose of this invention is to provide a retractable fireproof protection device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a telescopic fireproof protection device, comprising a support shell one and a support shell two, wherein a fixing block is fixedly connected to one side of the inner wall of the support shell one and the support shell two, and a hinge is fixedly connected to the side of the fixing block, and a fireproof plate is rotatably connected to the support shell one and the support shell two respectively through the hinge.
[0006] The fireproof board includes a fireproof board, a perforated heat transfer plate one, a perforated heat transfer plate two, a perforated heat transfer plate three, and a fireproof filter screen. One side of the fireproof filter screen is fixedly connected to one side of the perforated heat transfer plate three, the other side of the perforated heat transfer plate three is fixedly connected to one side of the perforated heat transfer plate two, the other side of the perforated heat transfer plate two is fixedly connected to one side of the perforated heat transfer plate one, and the other side of the perforated heat transfer plate one is fixedly connected to one side of the fireproof board. Adjacent fireproof boards are rotatably connected by hinges, and the hinges are fixed to the perforated heat transfer plate three. Two fireproof boards form a group, and two adjacent groups of fireproof boards are rotatably connected by hinges, and the hinges are fixed to the fireproof board.
[0007] Preferably, the aperture of the third perforated heat transfer plate is larger than that of the second perforated heat transfer plate, and the aperture of the second perforated heat transfer plate is larger than that of the first perforated heat transfer plate.
[0008] Preferably, a heat insulation board is fixedly connected to the side of the fireproof board away from the heat transfer plate with holes.
[0009] Preferably, both sides of the first and second support shells are fixedly connected with closing buckles.
[0010] Preferably, a handle is rotatably connected to one side of the second support shell.
[0011] Preferably, a placement groove is provided on one side of the second support shell, and the side of the handle is movably inserted into the inner wall of the placement groove.
[0012] Preferably, the three perforated heat transfer plates are all concave in shape.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention utilizes a perforated heat transfer plate (first, second, and third) and a fireproof filter to divide the flame. By employing the wall effect, the flame comes into contact with the inner walls of the perforated heat transfer plates, thereby enhancing the thermal conductivity of the flame and gradually lowering its temperature. This prevents the flame from spreading while simultaneously protecting the fireproof plate and extending its effective fireproof protection time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-8 This utility model provides a technical solution: a telescopic fireproof protection device, including a support shell 1 and a support shell 2. A fixing block 7 is fixedly connected to one side of the inner wall of the support shell 1 and the support shell 2. A hinge 6 is fixedly connected to the side of the fixing block 7. Fireproof plates 5 are rotatably connected to the support shell 1 and the support shell 2 respectively through the hinge 6.
[0026] The fireproof board 5 includes a fireproof board 51, a perforated heat transfer plate 52, a perforated heat transfer plate 53, a perforated heat transfer plate 54, and a fireproof filter 55. One side of the fireproof filter 55 is fixedly connected to one side of the perforated heat transfer plate 54, the other side of the perforated heat transfer plate 54 is fixedly connected to one side of the perforated heat transfer plate 53, the other side of the perforated heat transfer plate 53 is fixedly connected to one side of the perforated heat transfer plate 52, and the other side of the perforated heat transfer plate 52 is fixedly connected to one side of the fireproof board 51. Through the perforated heat transfer plate 52, perforated heat transfer plate 53, perforated heat transfer plate 54 and fireproof filter 55, the flame can be divided and heat conducted, thereby preventing the flame from spreading and extending the service life of the device. Adjacent fireproof plates 5 are rotatably connected by hinges 6, and the hinges 6 are fixed on the perforated heat transfer plate 54. Two fireproof plates 5 form a group, and two adjacent groups of fireproof plates 5 are rotatably connected by hinges 6, and the hinges 6 are fixed on the fireproof plate 51.
[0027] Furthermore, the aperture of the three-hole heat transfer plate 54 is larger than that of the two-hole heat transfer plate 53, and the aperture of the two-hole heat transfer plate 53 is larger than that of the one-hole heat transfer plate 52. The gradually decreasing aperture allows the flame heat to be conducted away quickly.
[0028] Furthermore, a heat insulation plate 8 is fixedly connected to the side of the fireproof plate 51 away from the heat transfer plate 52 with holes to reduce the heat transfer on the flame side.
[0029] Furthermore, both sides of the support shell 1 and the support shell 2 are fixedly connected with closing buckles 4, which can fix the support shell 1 and the support shell 2, thereby facilitating the movement and storage of the device.
[0030] Furthermore, a handle 3 is rotatably connected to one side of the second support shell 2, which facilitates both lifting and moving the device, and also makes it easy to pull the second support shell 2 for movement.
[0031] Furthermore, a placement groove is provided on one side of the support shell 2, which can be used to store the handle 3, thereby facilitating the support shell 2 to fit against the wall and improving the fireproof airtightness. The side of the handle 3 is movably inserted into the inner wall of the placement groove.
[0032] Furthermore, the perforated heat transfer plate 1 52, perforated heat transfer plate 2 53 and perforated heat transfer plate 3 54 are all concave, which provides space for the transfer of flame clusters among the perforated heat transfer plate 1 52, perforated heat transfer plate 2 53 and perforated heat transfer plate 3 54, while also increasing the heat conduction area of the flame.
[0033] When the device is needed, the closing latch 4 is opened, separating support shell 1 and support shell 2. Then, support shell 2 is moved and extended by pulling on handle 3. The fireproof plate 5 extends under the action of hinge 6. When multiple fireproof plates 5 extend to a single plane, the movement of support shell 2 is stopped. The fireproof plate 5, supported by support shells 1 and 2, is then placed vertically on the ground, with the fireproof filter 55 facing the flame. When the flame comes into contact with the fireproof plate 5 under the action of the airflow, the fireproof filter 5... 5 first disperses the concentrated flame into multiple small flame clusters. Then, as the flame passes through the progressively smaller aperture heat transfer plates 54, 53, and 52, the contact between the flame and the inner walls of the through holes in these plates is increased. This enhances the heat transfer effect under the wall effect, causing the flame temperature to gradually decrease. This not only prevents the spread of the flame but also protects the fireproof plate 51. Thus, the fireproof plate 5 can achieve the purpose of fire protection.
