Description

Technical Field

[0001] This utility model belongs to the technical field of emergency quick-stopping rods, specifically relating to an emergency quick-stopping rod for burst sprinkler heads. Background Technology

[0002] Sprinkler heads are used in fire sprinkler systems. In the event of a fire, water is sprayed out through the sprinkler head's splash plate for fire extinguishing. However, sprinkler heads often experience issues such as the glass bulb spontaneously exploding, causing a large amount of water to spray out. In such cases, it is necessary to notify professionals to shut off the valve, which takes a long time and cannot stop the flow as quickly as possible. Therefore, operators usually use an emergency quick-stopping rod to plug the leak. The existing emergency quick-stopping rod is a device used to quickly plug leaks in a short time when a sprinkler head bursts. Existing emergency quick-plugging rods, when used for emergency leak sealing of burst sprinkler heads, involve directly pulling off the internal drooping splash plate and inserting the guide pin on the quick-plugging rod into the frame hole of the sprinkler head for installation. However, the guide pin is fixed during installation, and its length and fixation make insertion into the hole in the sprinkler head's inner frame inconvenient, and even prevent quick and accurate installation for leak sealing. This affects the convenience of quick insertion and installation of the emergency quick-plugging rod when performing emergency leak sealing in burst sprinkler heads. Therefore, this utility model proposes an emergency quick-plugging rod for burst sprinkler heads. Utility Model Content

[0003] The purpose of this utility model is to provide an emergency quick-plugging rod for burst sprinkler heads, in order to solve the problem mentioned in the background art that when performing emergency plugging treatment on burst sprinkler heads, the limiting pin is fixed and long, making it inconvenient to insert into the holes of the sprinkler head's inner frame, or even impossible to quickly and accurately install the plugging treatment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an emergency quick-plugging rod for burst sprinkler heads, comprising a stainless steel sleeve, a threaded shaft connected internally to the stainless steel sleeve, a handwheel welded to the bottom end of the threaded shaft, a quick-plugging sealing head fixed to the top end of the threaded shaft by screws, a fixing block fixed to one side of the top end of the stainless steel sleeve by screws, a hook fixed to the surface of the fixing block by screws, a quick-insertion mechanism provided at the top end of the stainless steel sleeve on the outer surface of the threaded shaft, and a sloped drainage mechanism provided at the top end of the outer surface of the stainless steel sleeve; The quick insertion mechanism includes a quick insertion assembly located on the outer surface of the threaded shaft at the top of the stainless steel sleeve. The quick insertion assembly is used to insert into the hole of the spray head frame. A connecting assembly is provided on the lower surface of the quick insertion assembly located inside the stainless steel sleeve. A rotating pulling assembly is provided at the bottom end of the connecting assembly. A rotating assembly is provided at the bottom edge of the rotating pulling assembly. The inclined surface drainage mechanism includes an inclined surface drainage component fixed to the top of the outer surface of the stainless steel sleeve, and the inner surface of the inclined surface drainage component and the outer surface of the stainless steel sleeve are provided with support components.

[0005] Preferably, the quick insertion assembly includes a connecting ring disposed at the top of the stainless steel sleeve on the outer surface of the threaded shaft. The lower surface of the connecting ring is fixed to the top of the stainless steel sleeve by screws. One side of the lower surface of the connecting ring is fixed to the top of the fixing block by screws. A limiting groove is formed on one side of the inner side of the connecting ring. A limiting pin is limited inside the limiting groove. A compression spring is fixed between the tail end of the limiting pin and the inner tail end of the limiting groove.

[0006] Preferably, the limiting pin extends to the surface of the connecting ring, and the limiting pin is elastically connected to the interior of the limiting groove by the compression spring.

[0007] Preferably, the connecting assembly includes a thin steel wire fixedly installed at the end of the limiting lead pin by screws, and a pull rod sliding on one side of the inside of the stainless steel sleeve, the top end of the pull rod being fixed to the bottom end of the thin steel wire by screws.

[0008] Preferably, the rotary pulling assembly includes arc-shaped external threaded plates integrally disposed at both ends of the lower surface of the stainless steel sleeve, and a support ring integrally disposed at the bottom end of the two arc-shaped external threaded plates, and an internal threaded ring threadedly connected to the outer surface of the two arc-shaped external threaded plates.

[0009] Preferably, the rotating assembly includes a rotating groove formed at the inner edge of the internal threaded ring, rotating blocks rotating on both sides of the inner side of the rotating groove, and the ends of the rotating blocks being fixed to the bottom side of the pull rod by screws.

[0010] Preferably, the inclined drainage assembly includes a drainage inclined cover fitted onto the top of a stainless steel sleeve, and a fixing ring is integrally provided at the top of the drainage inclined cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By designing a quick-insertion mechanism, the limiting pin can be embedded into the limiting groove via a pull rod and a thin steel wire when the internal threaded ring moves downward. When the limiting pin encounters the hole in the frame body, the tension on the thin steel wire disappears, and the compression spring deforms, causing the limiting pin to pop out. This quickly aligns the pin with the hole and inserts it into the hole in the frame body, shortening the time for insertion and finding the hole in the frame body. It also extends the original length, making it less likely to fall out of the sprinkler head frame. It can also be installed on frames of different diameters inside the sprinkler head. When rotating, the limiting pin is locked in the sprinkler head frame. The quick-plug sealing head, driven by the threaded shaft, presses against the water outlet of the sprinkler head, achieving sealing. At the same time, the reaction force also makes the limiting pin press tightly and fix it between the sprinkler head frame body and the spray hole. This improves the convenience and accuracy of quickly inserting the stainless steel sleeve to seal the leak when the sprinkler head bursts. Attached Figure Description

Detailed Implementation

[0014] 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.

[0015] Please see Figures 1 to 8 This utility model provides a technical solution: an emergency quick-plugging rod for burst sprinkler heads, including a stainless steel sleeve 101, a threaded shaft 102 connected internally to the stainless steel sleeve 101, a handwheel 106 welded and fixed to the bottom end of the threaded shaft 102, a quick-plugging sealing head 103 fixed to the top end of the threaded shaft 102 by screws, a fixing block 104 fixed to one side of the top end of the stainless steel sleeve 101 by screws, a hook 105 fixed to the surface of the fixing block 104 by screws, a quick-insertion mechanism provided at the top end of the stainless steel sleeve 101 on the outer surface of the threaded shaft 102, and a slope drainage mechanism provided at the top end of the outer surface of the stainless steel sleeve 101. The quick insertion mechanism includes a quick insertion component located on the outer surface of the threaded shaft 102 at the top of the stainless steel sleeve 101. A connecting component is located inside the stainless steel sleeve 101 on the lower surface of the quick insertion component. A rotating pulling component is located at the bottom end of the connecting component. A rotating component is located at the bottom edge of the rotating pulling component. In the event of a burst sprinkler head, the quick insertion mechanism can quickly and accurately insert the top of the stainless steel sleeve 101 into the sprinkler head to seal the leak, preventing leakage.

[0016] To facilitate the quick insertion and installation of the stainless steel sleeve 101 and the top of the threaded shaft 102 using a quick-insertion assembly, in this embodiment, preferably, the quick-insertion assembly includes a connecting ring 1031 located on the top of the stainless steel sleeve 101 on the outer surface of the threaded shaft 102. The lower surface of the connecting ring 1031 is fixed to the top of the stainless steel sleeve 101 by screws, and one side of the lower surface of the connecting ring 1031 is fixed to the top of the fixing block 104 by screws. During leak sealing, the quick-plug sealing head 103 and the connecting ring 1031 can be pressed against the spray hole of the spray head. A limiting groove 1030 is formed on one side of the inner side of the connecting ring 1031. A limiting pin 1032 is fixed inside the limiting groove 1030. A compression spring 1039 is fixed between the tail end of the limiting pin 1032 and the inner tail end of the limiting groove 1030. The limiting pin 1032 is further secured by... The compression spring 1039 is in an elastic telescopic state. When inserted, the telescopic limiting pin 1032 can also be compressed inside the frame of the spray head. When it encounters a hole in the frame, the tension on its thin steel wire 1033 disappears, and the compression spring 1039 deforms, causing the limiting pin 1032 to pop out. This quickly aligns the pin with the hole and inserts it into the hole in the frame, shortening the time for the pin to be inserted and find the hole in the frame. It also extends the original length, making it less likely to fall out of the frame of the spray head. When rotating, the limiting pin 1032 is locked inside the frame of the spray head. The quick-block sealing head 103, driven by the threaded shaft, presses against the water outlet of the spray head, achieving a seal. At the same time, the reaction force also makes the limiting pin 1032 press tightly and fix it between the frame of the spray head and the water outlet, making it less likely to fall out and leak.

[0017] To facilitate the adjustment of the limiting pin 1032 by rotating and moving the internal threaded ring 1036 downwards via the connecting assembly, in this embodiment, preferably, the connecting assembly includes a thin steel wire 1033 fixedly installed at the tail end of the limiting pin 1032 by screws. A pull rod 1034 slides on one side of the inside of the stainless steel sleeve 101. The top end of the pull rod 1034 and the bottom end of the thin steel wire 1033 are fixed by screws (not shown in the figure). When the pull rod 1034 and the thin steel wire 1033 are subjected to tension, the limiting pin 1032 can be pulled closed by the thin steel wire 1033, facilitating the closure and installation.

[0018] To facilitate the pulling of the pull rod 1034 and the thin steel wire 1033 by rotating the pull assembly, and to make it easier to adjust the pull by rotating downward, in this embodiment, preferably, the pull assembly includes arc-shaped external threaded plates 1035 integrally disposed at both ends of the lower surface of the stainless steel sleeve 101. The bottom ends of the two arc-shaped external threaded plates 1035 are integrally provided with support rings. The outer surfaces of the two arc-shaped external threaded plates 1035 are threadedly connected with internal threaded rings 1036. The internal threaded rings 1036 can be rotated on the outer surface of the arc-shaped external threaded plates 1035 to drive the pull rod 1034 downward and pull it, thus facilitating the pulling of the pull rod 1034 and the thin steel wire 1033.

[0019] In order to facilitate the downward movement of the pull rod 1034 when the internal threaded ring 1036 is rotated by the rotating assembly, in this embodiment, preferably, the rotating assembly includes a rotating groove 1037 formed at the inner edge of the internal threaded ring 1036, and rotating blocks 1038 rotating on both sides inside the rotating groove 1037. The end of the rotating block 1038 is fixed to the bottom side of the pull rod 1034 by screws. When the internal threaded ring 1036 is rotated, the pull rod 1034 can be kept in the original position by rotating the rotating block 1038 inside the rotating groove 1037, and the downward movement of the pull rod 1034 can be adjusted.

[0020] The inclined drainage mechanism includes an inclined drainage component fixed to the top of the outer surface of the stainless steel sleeve 101. The inner surface of the inclined drainage component and the outer surface of the stainless steel sleeve 101 are provided with a support component. When the spray head is plugged, at the moment of contact between the quick-plug sealing head 103 and the water, the falling water is directly drained to the side through the inclined drainage mechanism, which makes it less likely to spray directly onto the operator, thus facilitating the protection of the operator during the plugging process.

[0021] To facilitate water diversion to the side during leak sealing of the upper spray head using the inclined diversion assembly, preventing water from spraying vertically onto the operator, this embodiment preferably includes a diversion inclined cover 1011 fitted onto the top of a stainless steel sleeve 101. A fixing ring 1012 is integrally provided at the top of the diversion inclined cover 1011. The fixing ring 1012 is fixed to the outer surface of the stainless steel sleeve 101 with screws. The diversion inclined cover 1011 can be fixedly installed using the fixing ring 1012. At the moment of contact during leak sealing, the sprayed water is diverted to the side through the diversion inclined cover 1011 and sprayed out, preventing it from spraying vertically onto the operator, thus facilitating diversion and protection.

[0022] To facilitate the installation and reinforcement of the drainage inclined shield 1011 using a support assembly, in this embodiment, preferably, the support assembly includes a second fixing ring 1013 fixedly mounted on the bottom end of a first fixing ring 1012 located on the outer surface of a stainless steel sleeve 101 by screws. The upper surface of the second fixing ring 1013 is connected and fixed to the inner surface edge of the drainage inclined shield 1011, and a support rod 1014 is fixed thereon. The support rod 1014 is installed through the second fixing ring 1013, and the support rod 1014 strengthens the support of the stainless steel sleeve 101, making it less prone to instability when the drainage is subjected to water impact.

[0023] The working principle and usage process of this utility model: When the emergency quick-plugging rod for bursting sprinkler heads bursts, a professional can directly hold the stainless steel sleeve 101 and place it on the lower surface of the quick-plugging sealing head 103, which is in contact with the surface of the connecting ring 1031 without being installed. The top of the stainless steel sleeve 101 contacts the bottom of the sprinkler head, and the operator can use the pull hook 105 below the sprinkler head to pull off the drooping splash plate. Before operation, rotate the inner thread ring 1036 on the outer surface of the arc-shaped external thread plate 1035. When the inner thread ring 1036 is rotated, the rotating block 1038 is driven to rotate inside the rotating groove 1037. Thus, when the inner thread ring 1036 is rotated, the pull rod 1034 is moved to the original position and pulled down. When the pull rod 1034 moves down, the limit pin 1032 is driven to embed into the limit slide groove 1030 through the thin steel wire 1033. During operation, the quick-plug sealing head 103 at the top of the stainless steel sleeve 101 and the threaded shaft 102 are initially embedded into the spray nozzle, and the connecting ring 1031 is also embedded. Then, the inner threaded ring 1036 is quickly rotated at the bottom of the stainless steel sleeve 101. The tension on the limiting pin 1032 by the pull rod 1034 and the thin steel wire 1033 disappears, and the compression spring 1039 deforms, causing the limiting pin 1032 to pop out. The pin is then quickly aligned with the hole and quickly inserted. The insertion time of the limiting pin 1032 into the hole of the frame body is shortened, and the time to find the hole on the frame body is shortened. The original length is also extended, making it less likely to fall out of the frame body of the sprinkler head. When rotating, the limiting pin 1032 is locked in the frame body of the sprinkler head for precise insertion and leak sealing. It can also be used for the frame bodies of sprinkler heads of different diameters, improving the convenience and accuracy of quickly inserting the stainless steel sleeve 101 to install and seal the leak when the sprinkler head bursts. After the stainless steel sleeve 101 is quickly inserted through the four limit pins 1032, the operator holds the handwheel 106 to drive the threaded shaft 102 to rotate and push it up until the quick-plug sealing head 103 seals and contacts the top of the spray head to stop the leak. This is convenient, quick and accurate in emergency leak stopping. Finally, before using the emergency quick-stopping rod, the fixing ring 1012 and fixing ring 2 1013 are fitted together again and installed on the top of the outer surface of the stainless steel sleeve 101 and fixed with bolts, thereby fixing the diversion slope cover 1011. After the diversion slope cover 1011 is fixedly installed, it is supported by the support rod 1014. Therefore, when the water sprayed from below the sprinkler head passes through the surface of the diversion slope cover 1011, it is diverted to the side with a certain slope and pressure, making it less likely to fall directly and impact the operator. This effectively improves the convenience of the emergency quick-stopping rod in diverting water and waterproofing the top of the stainless steel sleeve 101 when the sprinkler head bursts.

[0024] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
