Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a quick connection device for fire hydrants used in fire protection engineering. Background Technology

[0002] Outdoor fire hydrants are an important part of urban basic fire protection facilities and are widely used in public places, industrial parks, residential areas and other areas to provide water for firefighters in the event of a fire. Existing outdoor fire hydrants usually have standard interfaces, which require manual connection of fire hoses or external pipes to the interfaces, and then the valve is opened with a special wrench to release water for fire fighting. To prevent the misuse of water sources, these valves are designed to be opened with special tools to ensure the standardization and safety of use.

[0003] However, this traditional connection and activation method has many inconveniences. First, in an emergency fire scene, personnel often need to race against time to find a wrench and complete the steps of connecting fire hoses and opening valves, which is cumbersome and inefficient. Second, in the night or in environments with poor visibility, the tools are difficult to use and are prone to misoperation, which may even damage the interface components and affect the fire extinguishing efficiency. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a quick connection device for fire hydrants in fire protection engineering. By setting a built-in elastic sealing component and an automatic opening structure, the fire hose connector automatically opens the seal during the screwing process, eliminating the need to use a wrench to open the valve. This simplifies the connection operation process, improves the activation efficiency in emergency situations, and can effectively avoid misoperation and interface damage, especially at night or in emergency environments, ensuring the smooth progress of fire fighting operations.

[0006] To achieve the above objectives, this utility model proposes a quick-connect device for fire hydrants in fire protection engineering, comprising a fire hydrant, a connecting pipe symmetrically fixedly connected to the outer wall of the fire hydrant, a sealing cap threadedly fitted at the outlet of the connecting pipe, a sealing plate fixedly connected to the inner wall of the connecting pipe, an elastic sealing element provided on the sealing plate, a connector threadedly fitted at the outlet of the connecting pipe, one end of an abutment rod fixedly connected to one end of the inner wall of the connector, and the other end of the abutment rod abutting against one end of the elastic sealing element.

[0007] This utility model discloses a quick-connect device for fire hydrants in fire protection engineering. By tightening the connector, the built-in abutment rod gradually presses against the movable structure during the screwing process, causing the sliding plate and movable rod to move backward and compress the support spring, ultimately opening the water flow channel and achieving automatic water supply connection without the need for any tools. This structure not only achieves quick and automatic connection between the fire hydrant and the hose, but also ensures that the seal automatically resets after disconnection. It solves the problems of traditional technologies, such as the need for manual valve turning, cumbersome operation, reliance on tools, slow response, and damage to the interface due to misoperation. It significantly improves the response efficiency and safety reliability in fire protection operations, and is especially suitable for fire rescue scenarios with tight time constraints or low visibility.

[0008] In addition, the quick-connect device for fire hydrants in fire protection engineering proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the elastic seal includes a movable rod, a guide rod, a sliding plate, and a support spring. One end of the movable rod slides through one end of the sealing plate. One end of a plurality of guide rods is fixedly connected to one end of the sealing plate in a circumferential array. The sliding plate is slidably sleeved on the plurality of guide rods, and the inner wall of the sliding plate is fixedly connected to the other end of the movable rod. The support spring is disposed between one end of the sealing plate and the inner wall of the sliding plate, and is connected to the sealing plate through the support spring. The support spring is sleeved on the guide rod.

[0010] Specifically, a sealing sleeve is fixedly fitted onto the outer wall of the movable rod, a sealing gasket is fixedly connected to the inner wall of the sealing sleeve, and an abutment head is rotatably connected to one end of the movable rod.

[0011] Specifically, the other end of the guide rod is fixedly connected to a limiting head.

[0012] Specifically, the length of the abutment rod is greater than the length of the movable rod, and the end of the abutment head has anti-slip texture on the contact surface with the abutment rod.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] The following description, in conjunction with the accompanying drawings, describes a quick-connect device for fire hydrants used in fire protection engineering, according to an embodiment of this utility model.

[0023] like Figures 1-4 As shown, the quick-connect device for fire hydrants in fire protection engineering according to this utility model embodiment may include a fire hydrant 1, a connecting pipe 2 symmetrically fixedly connected to the outer wall of the fire hydrant 1, a sealing cap 3 threadedly fitted at the outlet of the connecting pipe 2, a sealing plate 4 fixedly connected to the inner wall of the connecting pipe 2, an elastic sealing element 5 provided on the sealing plate 4, a connector 6 threadedly fitted at the outlet of the connecting pipe 2, one end of an abutment rod 7 fixedly connected to one end of the inner wall of the connector 6, and the other end of the abutment rod 7 abutting against one end of the elastic sealing element 5.

[0024] It should be noted that, in this embodiment, the fire hydrant 1 is symmetrically and fixedly connected to a connecting pipe 2 on its outer wall. The connecting pipe 2 is used to quickly connect to an external fire hose or water supply device. A sealing cap 3 is threaded onto its outlet to effectively prevent dust, water, and foreign objects from entering when not in use, ensuring the cleanliness and sealing of the internal structure. A sealing plate 4 is fixedly connected to the inner wall of the connecting pipe 2. The sealing plate 4 is located in the middle of the pipe and acts as a fluid barrier through its tight fit with the inner wall of the pipe. An elastic sealing element 5 is provided on the sealing plate 4. This elastic sealing element 5 automatically rebounds to close the water outlet channel when no external equipment is connected, and deforms to open when squeezed by an external connection component. Its structural design may include a central movable rod 51, a guide limiting mechanism, and a matching elastic reset unit, thereby ensuring that during connection... The operation is smooth and the seal is reliable. A connector 6 can be threaded onto the outlet of the connecting pipe 2. The external thread of the connector 6 matches the thread of the pipe outlet. During the tightening process, it can automatically push the internal structure to open the seal. At the same time, the connector 6 has a quick locking function, which improves the efficiency of on-site installation. One end of the inner wall of the connector 6 is fixedly connected to one end of the abutment rod 7. The abutment rod 7 is used to directly contact and push the moving parts inside the elastic seal 5 during the connection process, so as to realize the automatic opening of the sealing mechanism. The other end of the abutment rod 7 abuts against one end of the elastic seal 5. Through cooperation with the rotatable sealing structure, the movable sealing mechanism is gradually pushed open during the continuous tightening of the connector 6, so that the water flow channel is opened. This ensures that a quick water connection can be achieved without the need for external tool intervention, which effectively improves the response speed and safety of fire operation.

[0025] The elastic seal 5 includes a movable rod 51, a guide rod 52, a sliding plate 53, and a support spring 54.

[0026] One end of the movable rod 51 slides through one end of the sealing plate 4. One end of multiple guide rods 52 is fixedly connected to one end of the sealing plate 4 in a circumferential array. The sliding plate 53 is slidably sleeved on the multiple guide rods 52, and the inner wall of the sliding plate 53 is fixedly connected to the other end of the movable rod 51. A support spring 54 is provided between one end of the sealing plate 4 and the inner wall of the sliding plate 53, and they are connected through the support spring 54. The support spring 54 is sleeved on the guide rod 52.

[0027] It should be noted that, in this embodiment, one end of the movable rod 51 slides through one end of the sealing plate 4. A wear-resistant guide ring and a sealing ring structure are provided between the movable rod 51 and the sealing plate 4 to enhance its sliding stability and sealing performance, preventing water leakage and impurity intrusion. One end of multiple guide rods 52 is fixedly connected to one end of the sealing plate 4 in a circumferential array. Each guide rod 52 is firmly connected to the sealing plate 4 by welding, and the arrangement is uniform and symmetrical. The sliding plate 53 is slidably sleeved on the multiple guide rods 52. A guide hole is provided on the inner side of the sliding plate 53, and the hole diameter is tightly matched with the guide rod 52 to ensure the straightness and stability during the sliding process. The inner wall of the sliding plate 53 is fixedly connected to the other end of the movable rod 51. The two can be rigidly connected by pin connection or welding, so that the sliding plate 53 can synchronously drive the movable rod 51 to move axially when subjected to external pressure or elastic force, realizing the opening and closing linkage of the sealing structure. A support spring 54 is provided between one end of the sealing plate 4 and the inner wall of the sliding plate 53. The support spring 54 is made of high-strength stainless steel spring material, which has good fatigue resistance and restoring force, ensuring the reliability of the structure under long-term high-frequency use. The spring can store energy after being compressed and quickly reset the sliding plate 53 and the movable rod 51 to the sealed state when there is no external force.

[0028] Specifically, when the fire hydrant 1 is not in use, the support spring 54 drives the movable rod 51 to a forward position via the sliding plate 53. The movable rod 51 achieves a sealing closure at the opening of the sealing plate 4, thereby preventing water flow. With the cooperation of the sealing ring and the guide structure, the sealing performance and dustproof and impurity prevention effects are ensured. When it is necessary to connect the fire hose, the user screws the connector 6 into the threaded interface of the connecting pipe 2. As the screwing process continues, the abutment rod 7 inside the connector 6 gradually presses against the movable structure of the elastic seal 5. Through the cooperation of the abutment rod 7 and the abutment head 512 on the movable rod 51, the sliding plate 53 is pushed along the direction of the guide rod 52 to stretch the support spring 54, so that the movable rod 51 moves backward, thereby opening the opening of the sealing plate 4 and completing the opening of the water flow channel. During this process, there is no need to use external tools such as wrenches to operate the valve, which effectively improves the connection and water supply efficiency. This technical solution, through its built-in automatic opening and closing structure and self-resetting sealing component, completely solves the problems of traditional fire hydrants requiring special tools to open valves, cumbersome operation, and untimely response. It also avoids the risks of misoperation and interface damage caused by the difficulty in using tools. It is particularly suitable for emergency fire scenarios and environments with low visibility at night, significantly improving the safety, speed, and reliability of fire emergency response.

[0029] Furthermore, such as Figure 1As shown, a sealing sleeve 511 is fixedly sleeved on the outer wall of the movable rod 51, and a sealing gasket is fixedly connected to the inner wall of the sealing sleeve 511. One end of the movable rod 51 is rotatably connected to an abutment head 512, and the other end of the guide rod 52 is fixedly connected to a limit head 521. The length of the abutment rod 7 is greater than the length of the movable rod 51, and the contact surface between the end of the abutment head 512 and the contact surface of the abutment rod 7 is provided with anti-slip texture.

[0030] It should be noted that the inner wall of the sealing sleeve 511 described in this embodiment is fixedly connected with a sealing gasket. The sealing gasket is made of flexible high-temperature resistant silicone material, which has good resilience and wear resistance. It can effectively press the opening of the sealing plate 4 during the return of the movable rod 51, thereby enhancing the airtightness and watertightness in the closed state. One end of the movable rod 51 is rotatably connected to an abutment head 512. The abutment head 512 is connected to the movable rod 51 through a rotating shaft and can rotate during the pushing of the abutment rod 7, thereby reducing the top pressure friction and reducing structural wear, and extending the service life.

[0031] In summary, the fire hydrant quick-connect device for fire protection engineering of this utility model, by tightening the connector 6, causes its built-in abutment rod 7 to gradually press against the movable structure during the screwing process, driving the sliding plate 53 and the movable rod 51 to move backward and compress the support spring 54, ultimately opening the water flow channel and realizing automatic water supply connection without the need for any tools. This structure not only realizes the quick and automatic connection between the fire hydrant 1 and the water hose, but also ensures that the sealing element can automatically reset and seal after disconnection. It solves the problems of traditional technology, such as the need for manual valve turning, cumbersome operation, reliance on tools, untimely response, and interface damage caused by misoperation. It significantly improves the response efficiency and safety reliability in fire protection operations, and is especially suitable for fire rescue scenarios with tight time or low visibility.
