Description

Technical Field

[0001] This invention relates to the field of fire protection system technology, and in particular to a quick-stopping device and method for stopping water leakage when the sprinkler head of a wet automatic sprinkler system ruptures. Background Technology

[0002] Wet sprinkler systems are among the most widely used automatic fire suppression systems, found in civil buildings (residential, office buildings), industrial buildings (factories, warehouses, logistics parks), and other building types. Wet sprinkler systems utilize closed sprinkler heads installed in each fire compartment to automatically spray water into the affected area when a fire occurs, thus achieving automatic fire suppression.

[0003] In actual use, the sprinkler heads of wet automatic sprinkler systems may crack due to the following reasons: 1) Spray head spontaneously explodes due to natural aging or thermal expansion and contraction; 2) Damaged by external impact (such as collision during operation or damage caused by human intervention).

[0004] A broken shower head can cause the following problems: 1) After the sprinkler head breaks, a large amount of pressurized water is sprayed out from the wet automatic sprinkler system network. Since the network covers a large area of ​​the fire compartment and the pipeline is long, it takes a long time to release the pressure by closing the nearest valve. This will result in a long drainage time and waste of water resources. 2) During the pipeline depressurization period, on-site personnel cannot take effective measures to deal with the damaged and leaking sprinkler heads. They can only wait for the drainage to be completed for a long time before replacing the sprinkler heads with new ones to stop the water. 3) Items and vehicles under the sprinkler head being sprayed with water for a long time may cause certain losses or safety risks; at the same time, if the water is not stopped in time, the losses may be expanded due to water immersion, such as water leakage in high-rise buildings flowing into elevators or indoors, causing damage to equipment, facilities and building decorations. Summary of the Invention

[0005] Based on this, a quick-stop device for sealing broken sprinkler heads in wet automatic sprinkler systems is provided. This device facilitates the rapid sealing of the sprinkler head's outlet.

[0006] The specific plan is as follows: A quick-stop device for preventing water damage to a sprinkler head in a wet automatic sprinkler fire extinguishing system includes a clamping and positioning mechanism. The clamping and positioning mechanism is equipped with a first positioning plate and a second positioning plate. A sealing element is provided on the surface of the first positioning plate, and a notch is provided on the second positioning plate for inserting the sprinkler head body. The clamping and positioning mechanism has at least two postures: a first posture and a second posture. In the first posture, the sealing element of the first positioning plate is away from the second positioning plate. In the second posture, the sealing element of the first positioning plate is close to the second positioning plate. At this time, the sealing element is used to block the water outlet of the sprinkler head.

[0007] In one embodiment, when the clamping and positioning mechanism is in the second posture, the clamping and positioning mechanism is simultaneously in a locked state.

[0008] In one embodiment, the clamping and positioning mechanism is a clamping pliers, which includes a first jaw and a second jaw, with a first positioning plate fixed on the first jaw and a second positioning plate fixed on the second jaw.

[0009] In one embodiment, the sealing element is a rubber sealing element.

[0010] In one embodiment, the rubber sealing element is a rubber plate, which is used to fit tightly against the water outlet.

[0011] In one embodiment, the sealing element is connected to the first positioning plate by bolts.

[0012] In one embodiment, both the first positioning plate and the second positioning plate are steel plates.

[0013] A method for quickly stopping water leakage from a ruptured sprinkler head in a wet-type automatic sprinkler system, employing the aforementioned quick-stopping device for a ruptured sprinkler head in a wet-type automatic sprinkler system. First, insert the body of the spray head into the notch of the second positioning plate, so that the first positioning plate is above the water outlet of the spray head. Then, move the first positioning plate toward the water outlet through the clamping and positioning mechanism until the water outlet is blocked by the sealing member.

[0014] In one embodiment, when water is no longer supplied to the shower head, the first positioning plate is moved away from the water outlet by the clamping and positioning mechanism, and then the second positioning plate is separated from the body of the shower head.

[0015] The beneficial effects of this application are as follows: 1. When the wet system sprinkler head spontaneously bursts due to natural aging or thermal expansion and contraction, or is damaged by external impact or human error, the device of this application can be used to achieve rapid water stop under pressure.

[0016] 2. Prevents damage to more items and effectively reduces potential risks to pedestrians and vehicles.

[0017] 3. The device of this application is simple and convenient to operate, and it seals the outlet tightly without leakage. It uses a bolt clamp as a clamping and positioning mechanism. After clamping, it can be released to block the outlet.

[0018] 4. The device described in this application has low manufacturing cost and is easy to promote and use.

[0019] 5. Wide range of applications. Attached Figure Description

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] like Figures 1 to 6 As shown, an embodiment of this application provides a quick-stop device for a broken sprinkler head in a wet automatic sprinkler fire extinguishing system, including a clamping and positioning mechanism. The clamping and positioning mechanism is provided with a first positioning plate 110 and a second positioning plate 140. The first positioning plate 110 is provided with a sealing member 120, and the second positioning plate 140 is provided with a notch 141 for inserting the body 210 of the sprinkler head. The body 210 of the sprinkler head is connected to a sprinkler pipe interface 250, and the sprinkler pipe is used to supply water to the sprinkler head. The clamping and positioning mechanism has at least two postures, namely a first posture and a second posture. In the first posture, the sealing member 120 of the first positioning plate 110 is away from the second positioning plate 140. In the second posture, the sealing member 120 of the first positioning plate 110 is close to the second positioning plate 140. At this time, the sealing member 120 is used to block the water outlet 220 of the sprinkler head.

[0030] Specifically, when the shower head breaks, the body 210 of the shower head is inserted into the notch 141 of the second positioning plate 140, thus mounting the second positioning plate 140 onto the shower head body. There is a step between the shower head body 210 and the outlet 220, and the second positioning plate 140 is located on one side of this step. Thus, as the sealing member 120 of the first positioning plate 110 moves towards the outlet 220, the second positioning plate 140 is blocked by the step and cannot move. Ultimately, the sealing member 120 of the first positioning plate 110 can seal the outlet 220 of the shower head.

[0031] It should be noted that when the clamping and positioning mechanism is in the second posture, it is also in a locked state. That is, after the sealing member 120 blocks the outlet 220, the clamping and positioning mechanism is in a locked state. Maintenance personnel do not need to continuously operate the clamping and positioning mechanism; they can release it. At this time, because the clamping and positioning mechanism is in a locked state, the outlet 220 is still blocked by the sealing member 120, which prevents water from spraying out. Next, the maintenance personnel can close the corresponding valve. Once the valve is closed, water is no longer supplied to the broken sprinkler head. After the system pipeline has drained the remaining water, the damaged sprinkler head can be replaced.

[0032] In one embodiment, the clamping and positioning mechanism is a clamping clamp 150, which includes a first clamping jaw 151 and a second clamping jaw 152. A first positioning plate 110 is fixed on the first clamping jaw 151, and a second positioning plate 140 is fixed on the second clamping jaw 152.

[0033] Specifically, there are various implementation methods for the clamping and positioning mechanism. This mechanism enables the first positioning plate 110 and the second positioning plate 140 to approach each other, and seals the outlet 220 through the sealing member 120 on the first positioning plate 110. The clamping and positioning mechanism also has locking and unlocking functions. In the prior art, a tool called a bolt clamp 150 can be used as a clamping and positioning mechanism. The bolt clamp 150's jaws can lock and generate a large clamping force without loosening, and the jaws have multiple adjustable positions for clamping spray heads of different thicknesses. Field tests show that when the spray pipe pressure is 0.45 MPa or greater, the device described in this application can stop water under pressure, and the seal is tight and leak-free; after clamping, it can be released.

[0034] Specifically, the first positioning plate 110 can be fixed to the first jaw 151 by welding or other means, and the second positioning plate 140 can be fixed to the second jaw 152 by welding or other means.

[0035] Specifically, the materials used for the first positioning plate 110 and the second positioning plate 140 need to be resistant to deformation under certain external forces. For example, both the first positioning plate 110 and the second positioning plate 140 are steel plates.

[0036] Based on the above, in one embodiment, the sealing member 120 is a rubber sealing member 120. The rubber sealing member 120 can effectively seal the outlet 220.

[0037] Specifically, the rubber sealing element 120 is a rubber plate, which is used to tightly fit against the outlet 220. When the end face of the outlet 220 is flat, the rubber sealing element 120 is a rubber plate, which fits tightly against the outlet 220, thus effectively sealing the outlet 220. It can be understood that the shape of the rubber sealing element 120 can also be matched to the shape of the outlet 220.

[0038] In one embodiment, such as Figures 1 to 3 As shown, the sealing component 120 is connected to the first positioning plate 110 by bolts 130.

[0039] Specifically, the sealing component 120 is a rubber plate, which is connected to the first positioning plate 110 by bolts 130. With this configuration, when the rubber plate needs to be replaced, the old rubber plate can be separated from the first positioning plate 110, and then the new rubber plate can be connected to the first positioning plate 110 by bolts 130.

[0040] like Figure 5 and Figure 6 As shown, an embodiment of this application also provides a method for quickly stopping the water flow when a sprinkler head of a wet automatic sprinkler fire extinguishing system breaks. Using the aforementioned quick-stopping device for a sprinkler head of a wet automatic sprinkler fire extinguishing system, the body 210 of the sprinkler head is first inserted into the notch 141 of the second positioning plate 140, so that the first positioning plate 110 is positioned above the water outlet 220 of the sprinkler head. Then, the first positioning plate 110 is moved toward the water outlet 220 by a clamping and positioning mechanism until the water outlet 220 is blocked by the sealing member 120.

[0041] Based on the above, in one embodiment, when water is no longer supplied to the spray head, the first positioning plate 110 is moved away from the water outlet 220 by the clamping and positioning mechanism, and then the second positioning plate 140 is separated from the body 210 of the spray head.

[0042] The method described in this application can achieve rapid water sealing under pressure, and is simple and convenient to operate. It is low in cost and has a wide range of applications.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
