Description

Technical Field

[0001] The utility model relates to the technical field of fireproof rolling curtains, in particular to a steel fireproof rolling curtain with a water cooling device. Background Art

[0002] Fire shutter doors are mostly used in fire partitions and fire passages of building structures to prevent the spread of fire and buy time for firefighting. However, their thermal insulation performance is poor and it is difficult to meet national standards within the specified time, so water cooling protection methods are needed for forced cooling. The water cooling protection technology for fire shutter doors currently used in the market consumes too much water, which poses a great challenge to the fire water supply capacity of large buildings or high-rise buildings. The water supply of some buildings cannot even meet the normal use of water spray shutter doors. Utility Model Content

[0003] The purpose of the utility model is to provide a steel fireproof roller shutter with a water cooling device to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0005] A steel fireproof roller shutter with a water cooling device comprises a steel fireproof roller shutter, a winding device, a side guide rail, a solenoid valve and a detection device, wherein the water supply end of the solenoid valve is fixedly connected to a water supply hose for water cooling the steel fireproof roller shutter, the bottom end outer wall of the water supply hose is in contact with one side of the steel fireproof roller shutter, the side of the water supply hose close to the steel fireproof roller shutter is fixedly connected to a horizontal water spray pipe, and the bottom surface of the horizontal water spray pipe is provided with a spray hole.

[0006] A closing plate is fixedly connected to the back of the steel fireproof roller shutter, a water storage tank is provided on the back of the steel fireproof roller shutter, a water bottom hole is provided on the inner wall of the water storage tank, a closing rod for closing drainage is inserted into the inner wall of the water bottom hole, and a float is fixedly connected to the top of the closing rod.

[0007] The above-mentioned technical scheme is adopted, in which the electromagnetic valve, water supply hose, horizontal water spray pipe and spray hole are used in coordination, so that after the steel fireproof roller shutter is unfolded, cooling water can be sprayed more evenly onto the steel fireproof roller shutter, thereby improving the cooling effect thereof.

[0008] A further improvement of the technical solution of the utility model is that a positioning collar is sleeved on the outer wall of the water supply hose, and one end of the positioning collar away from the water supply hose is fixedly connected to one side of the steel fireproof roller shutter.

[0009] A further improvement of the technical solution of the utility model is that: the outer wall at the top end of the closed plug rod is provided with a water inlet groove for drainage.

[0010] The above-mentioned technical scheme is adopted, in which a part of the cooling water can be stored in the water storage tank, which can continuously absorb heat from the steel fireproof roller shutter. When the cooling water in the water storage tank accumulates to a certain level, the buoyancy of the accumulated water on the float will push it to drive the closing rod to move upward from the inner wall of the lower water bottom hole, thereby releasing the closing effect of the float on the lower water bottom hole. The cooling water will be discharged downward through the lower water bottom hole, thereby regulating the overall weight of the steel fireproof roller shutter. At the same time, when the cooling water is discharged downward, the cooling effect on the surface of the steel fireproof roller shutter can be further enhanced.

[0011] A further improvement of the technical solution of the utility model is that the bottom of the inner wall of one end of the winding device is fixedly connected to the bottom surface of the detection device.

[0012] A further improvement of the technical solution of the utility model is that the top of the solenoid valve is fixedly connected to the top of the inner wall of the winding device.

[0013] A further improvement of the technical solution of the utility model is that a reeling rod is arranged inside the reeling device, and the water supply hose is wound around the outer wall of one end of the reeling rod.

[0014] A further improvement of the technical solution of the utility model is that one end of the winding device is fixedly connected with a limiting guide roller for guiding the water supply hose.

[0015] A further improvement of the technical solution of the utility model is that a smoke sensor and a temperature sensor are arranged inside the detection device.

[0016] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0017] 1. The utility model provides a steel fireproof rolling curtain with a water cooling device. By using a solenoid valve, a water supply hose, a horizontal water spray pipe and a spray hole in coordination, the steel fireproof rolling curtain can spray cooling water more evenly onto the steel fireproof rolling curtain after it is unfolded, thereby improving the cooling effect thereof.

[0018] 2. The utility model provides a steel fireproof roller shutter with a water cooling device. A portion of cooling water can be stored in the water storage tank, which can continuously absorb heat from the steel fireproof roller shutter. When the cooling water in the water storage tank accumulates to a certain amount, the buoyancy of the accumulated water on the float will push it to drive the closing rod to move upward from the inner wall of the lower water bottom hole, thereby releasing the closing effect of the float on the lower water bottom hole. The cooling water will be discharged downward through the lower water bottom hole to regulate the overall weight of the steel fireproof roller shutter. At the same time, when the cooling water is discharged downward, the cooling effect on the surface of the steel fireproof roller shutter can be further enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The present invention is further described in detail below in conjunction with the embodiments:

[0027] Example 1

[0028] like Figure 1-5 As shown, the utility model provides a steel fireproof roller shutter with a water cooling device, including a steel fireproof roller shutter 1, a winding device 2, a side guide rail 3, a solenoid valve 5 and a detection device 8, the water supply end of the solenoid valve 5 is fixedly connected with a water supply hose 6 for water cooling the steel fireproof roller shutter 1, the bottom end outer wall of the water supply hose 6 is in contact with one side of the steel fireproof roller shutter 1, and the side of the water supply hose 6 close to the steel fireproof roller shutter 1 is fixedly connected with a horizontal water spray pipe 9, and a spray hole 11 is provided on the bottom surface of the horizontal water spray pipe 9.

[0029] A closing plate 12 is fixedly connected to the back of the steel fireproof roller shutter 1, and a water storage tank is provided on the back of the steel fireproof roller shutter 1. A lower water hole 14 is provided on the inner wall of the water storage tank, and a closing plug rod 13 for closing and draining is inserted into the inner wall of the lower water hole 14, and a floating ball 16 is fixedly connected to the top of the closing plug rod 13. The water storage tank can store a part of the cooling water therein, and can continuously absorb heat from the steel fireproof roller shutter 1. When the cooling water in the water storage tank accumulates to a certain level, the buoyancy of the accumulated water on the floating ball 16 will push it to drive the closing plug rod 13 to move upward from the inner wall of the lower water hole 14, thereby releasing the closing effect of the floating ball 16 on the lower water hole 14, and the cooling water will be discharged downward through the lower water hole 14, thereby regulating the overall weight of the steel fireproof roller shutter 1. At the same time, when the cooling water is discharged downward, the cooling effect on the surface of the steel fireproof roller shutter 1 can also be further enhanced.

[0030] Example 2

[0031] like Figure 1-5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the outer wall of the water supply hose 6 is sleeved with a positioning ring 10, and the end of the positioning ring 10 away from the water supply hose 6 is fixedly connected to one side of the steel fireproof roller shutter 1.

[0032] A water inlet groove 15 for drainage is provided on the outer wall of the top end of the closing rod 13 , and the bottom of the inner wall at one end of the winding device 2 is fixedly connected to the bottom surface of the detection device 8 .

[0033] The top of the solenoid valve 5 is fixedly connected to the top of the inner wall of the winding device 2 . A winding rod 4 is arranged inside the winding device 2 , and a water supply hose 6 is wound around the outer wall of one end of the winding rod 4 .

[0034] One end of the winding device 2 is fixedly connected to a limiting guide roller 7 for guiding the water supply hose 6. When the steel fireproof roller shutter 1 moves downward and unfolds, the water supply hose 6 will move downward smoothly under the guidance of the limiting guide roller 7. When the winding device 2 winds up the steel fireproof roller shutter 1, the winding rod 4 can wind up the water supply hose 6 to facilitate the storage of the water supply hose 6. The detection device 8 is provided with a smoke probe and a temperature probe.

[0035] The following is a detailed description of the working principle of the steel fireproof roller shutter with water cooling device.

[0036] like Figure 1-5As shown, during use, after the detection device 8 detects a fire, the winding device 2 receives a signal to open the steel fireproof roller shutter 1, causing it to be lowered and unfolded, and at the same time, the solenoid valve 5 receives a signal to open, and the cooling water in the water pipe external to the solenoid valve 5 is transported to the water supply hose 6, and then transported to the horizontal water spray pipe 9, and then sprayed through the spray hole 11 onto the back of the steel fireproof roller shutter 1 to cool it, and the excess water will be stored in the water storage tank, and at the same time, a plurality of horizontal water spray pipes 9 are used to synchronously cool different areas of the steel fireproof roller shutter 1, thereby improving the overall water-cooling cooling effect of the steel fireproof roller shutter 1.

[0037] When the cooling water in the water storage tank accumulates to a certain level, the buoyancy generated by the accumulated water on the float 16 will push it to drive the closing rod 13 to move upward from the inner wall of the lower water bottom hole 14, thereby releasing the closing effect of the float 16 on the lower water bottom hole 14. As a result, the cooling water will fall into the next water storage tank through the lower water bottom hole 14, ensuring that the water level in the water storage tank is within a certain range. At the same time, the lower water bottom hole 14 can also be used to cool other areas of the steel fireproof roller shutter 1, further improving the cooling effect of the steel fireproof roller shutter 1.

[0038] When the steel fireproof roller shutter 1 moves downward and unfolds, the water supply hose 6 will move downward smoothly under the guidance of the limiting guide roller 7, and when the reeling device 2 reels the steel fireproof roller shutter 1, the reeling rod 4 can reel up the water supply hose 6 to facilitate the storage of the water supply hose 6.

[0039] It should be noted that, in this article, the terms "comprises", "includes" or any other variants are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or still includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements. The above generally describes the utility model in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to it based on the utility model. Therefore, modifications or improvements that do not deviate from the spirit of the utility model are within the scope of protection of the utility model.
