Description

Technical Field

[0001] This application relates to the field of fire protection facilities technology, and in particular to a fire hydrant for fire protection engineering. Background Technology

[0002] A fire hydrant is a device that provides water to fire trucks for firefighting operations. It is typically installed inside or around buildings. It is an important component of urban fire protection systems, used to provide water for extinguishing fires, control combustibles, isolate oxidizers, and eliminate ignition sources, thereby protecting people's lives and property.

[0003] A published patent document (CN209798893U) discloses a fire hydrant for fire protection engineering that is easy to connect. The hydrant includes a hydrant body, a connecting pipe, a fixed bucket, a hose connector, a placement groove, a movable ring, a movable groove, a bearing, a fixing block, a locking rod, a spring, a pull rod, a locking groove, a threaded block, a handle, and threaded teeth. The fixed bucket is fixedly installed on the right side of the hydrant body, and the connecting pipe is fixedly installed inside the fixed bucket on the right side of the hydrant body. A placement groove is formed on the outer wall of the hose connector, and a movable ring is movably installed inside the placement groove. This easily connectable fire hydrant solves the problem that fire hydrants used in fire protection engineering cannot be quickly connected to hoses, which is crucial in firefighting as time is of the essence. Failure to connect the hose to the fire hydrant in a timely manner increases the risk of fire and affects the efficiency of firefighting.

[0004] When the water flow rate is too high, the connection between the hose connector and the connecting pipe relies on the spring force and the threaded teeth and threaded blocks to maintain the connection. However, vibration will occur when the water pressure is high or the water flow rate is too high. In this case, the threaded teeth and threaded blocks may be separated by vibration. The spring force is not enough to resist the separation force generated by the water flow, and there is a risk that the connection between the hose connector and the connecting pipe is not secure. Therefore, this application provides a fire hydrant for fire protection engineering. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a fire hydrant for fire protection engineering, which overcomes the deficiencies of existing technologies. It aims to solve the problem that when the water flow velocity of the above devices is too high, the connection between the hose connector and the connecting pipe relies on the thrust of the spring and the threaded teeth and threaded blocks to maintain the connection. However, when the water pressure or the water flow velocity is too high, vibration will occur. In this case, the threaded teeth and threaded blocks may be separated by vibration. The tension of the spring is insufficient to resist the separation force generated by the water flow, which poses a risk of unreliable connection between the hose connector and the connecting pipe.

[0006] To achieve the above objectives, this application provides the following technical solution: a fire hydrant for fire protection engineering, comprising a fire hydrant body and a hose, a connecting pipe fixedly installed on one side of the fire hydrant body, a fixing ring fixedly installed on the outer surface of the hose, a threaded connector fixedly installed at one end of the hose, the threaded connector being threadedly connected to the inside of the connecting pipe, a rotating mechanism fixedly installed on both the upper and lower sides of the connecting pipe, a C-shaped seat fixedly installed at the top of the rotating mechanism, a connecting rod rotatably connected inside the C-shaped seat, a spring installed at the bottom end of the connecting rod, and the bottom end of the spring being installed on the inner wall of the C-shaped seat.

[0007] By adopting the above technical solution, the C-shaped seat is rotated by a rotating mechanism, and then the fixing ring is connected to the connecting pipe by a threaded connector. The rotating handle facilitates the rotation of the threaded connector. Rotating the threaded connector keeps the two sets of rotating handles perpendicular. Then, the rotating mechanism rotates the C-shaped seat towards the rotating handle, and at the same time, the connecting rod is rotated upward by the C-shaped seat. When the limiting ring is directly above the rotating handle, the connecting rod can be rotated downward so that the limiting ring fits on the outer surface of the rotating handle, thus fixing the rotating handle. The fixing process for the two sets of rotating handles is the same. At the same time, the position of the connecting rod is limited by the action of the spring to prevent the connecting rod from rotating automatically. By fixing the rotating handle to fix the fixing ring, the reliability of the connection between the connecting pipe and the water hose is improved.

[0008] As a preferred technical solution of this application, the rotating mechanism includes a rotating seat, which is fixedly installed at the top end of the connecting pipe. A rotating rod is rotatably connected inside the rotating seat, and the top of the rotating rod is fixedly installed at the bottom of the C-shaped seat. The connecting rod is a telescopic rod.

[0009] By adopting the above technical solution, when connecting the fixing ring and the connecting pipe, the C-shaped seat is rotated by the rotating rod, which facilitates the rotation of the position of the connecting rod and the limiting ring without affecting the connection between the fixing ring and the connecting pipe. At the same time, since the connecting rod is a telescopic rod, it has a certain degree of tolerance for the position of the rotating handle. The limiting ring and the rotating handle can be connected by adjusting the length of the connecting rod, which improves the practicality during use.

[0010] As a preferred embodiment of this application, a sealing ring is fixedly installed inside the connecting pipe, and the threaded connector abuts against the sealing ring.

[0011] By adopting the above technical solution, the gap between the connecting pipe and the threaded connector is greatly reduced by the sealing ring, thus improving the sealing performance of the connection between the connecting pipe and the threaded connector.

[0012] As a preferred embodiment of this application, the spring is provided with a telescopic guide rod inside, the bottom end of the telescopic guide rod is installed on the inner wall of the C-shaped seat, and the telescopic end of the telescopic guide rod is installed on the bottom end of the connecting rod.

[0013] By adopting the above technical solution, the telescopic guide rod plays a guiding role in the elastic extension and contraction of the spring, which helps to improve the service life of the spring.

[0014] As a preferred technical solution of this application, the inner ring of the limiting ring is fixedly installed with an anti-slip ring.

[0015] By adopting the above technical solution, the anti-slip effect is increased when the limiting ring and the rotating handle are connected by the anti-slip ring, further reducing the possibility of accidental separation between the limiting ring and the rotating handle.

[0016] As a preferred technical solution of this application, both the outer surfaces of the spring and the telescopic guide rod are coated with a waterproof layer.

[0017] By adopting the above technical solution, the impact of moisture on the spring and telescopic guide rod is reduced through the waterproof layer, thus reducing the possibility of rust and improving the waterproof effect of the spring and telescopic guide rod, which is beneficial to the long-term use of the spring and telescopic guide rod.

[0018] The beneficial effects of this application are:

[0019] 1. The C-shaped seat is rotated by a rotating mechanism, and then the fixing ring is connected to the connecting pipe through a threaded connector. The threaded connector is rotated by a rotating handle. Rotating the threaded connector keeps the two sets of rotating handles perpendicular. Then, the C-shaped seat is rotated in the direction of the rotating handle by the rotating mechanism. At the same time, the connecting rod is rotated upward by the C-shaped seat. When the limiting ring is directly above the rotating handle, the connecting rod can be rotated downward so that the limiting ring fits on the outer surface of the rotating handle and fixes the rotating handle. The fixing process for the two sets of rotating handles is the same. At the same time, the position of the connecting rod is limited by the action of the spring to prevent the connecting rod from rotating automatically. Fixing the fixing ring by fixing the rotating handle improves the reliability of the connection between the connecting pipe and the water hose.

[0020] 2. When connecting the fixing ring to the connecting pipe, the C-shaped seat is rotated by rotating the rod, which facilitates the rotation of the connecting rod and the limiting ring without affecting the connection between the fixing ring and the connecting pipe. At the same time, the connecting rod is a telescopic rod, which has a certain degree of tolerance for the position of the rotating handle. The limiting ring and the rotating handle can be connected by adjusting the length of the connecting rod, which improves the practicality during use. Attached Figure Description

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] Reference Figure 1-3 A fire hydrant for fire protection engineering includes a fire hydrant body 1 and a hose 3. A connecting pipe 2 is fixedly installed on one side of the fire hydrant body 1. A fixing ring 4 is fixedly installed on the outer surface of the hose 3. A threaded connector 5 is fixedly installed at one end of the hose 3. The threaded connector 5 is threaded into the inside of the connecting pipe 2. Rotating mechanisms 7 are fixedly installed on both the upper and lower sides of the connecting pipe 2. A C-shaped seat 8 is fixedly installed at the top of the rotating mechanism 7. A connecting rod 9 is rotatably connected inside the C-shaped seat 8. A limit ring 10 is provided at the end of the connecting rod 9 away from the C-shaped seat 8. A spring 11 is installed at the bottom end of the connecting rod 9. The bottom end of the spring 11 is installed on the inner wall of the C-shaped seat 8. A sealing ring is fixedly installed inside the connecting pipe 2. The threaded connector 5 abuts against the sealing ring.

[0028] The C-shaped seat 8 is rotated by the rotating mechanism 7, and then the fixing ring 4 is connected to the connecting pipe 2 by the threaded connector 5. The rotating handle 6 facilitates the rotation of the threaded connector 5. Rotating the threaded connector 5 keeps the two sets of rotating handles 6 perpendicular. Then, the rotating mechanism 7 rotates the C-shaped seat 8 towards the rotating handle 6, and at the same time, the C-shaped seat 8 rotates the connecting rod 9 upward. When the limiting ring 10 is directly above the rotating handle 6, the connecting rod 9 can be rotated downward so that the limiting ring 10 fits on the outer surface of the rotating handle 6, fixing the rotating handle 6. The fixing process for the two sets of rotating handles 6 is the same. At the same time, under the action of the spring 11, the position of the connecting rod 9 is limited to prevent the connecting rod 9 from rotating automatically. Fixing the fixing ring 4 by fixing the rotating handle 6 improves the reliability of the connection between the connecting pipe 2 and the water hose 3. The sealing ring greatly reduces the gap when the connecting pipe 2 and the threaded connector 5 are connected, improving the sealing performance when the connecting pipe 2 and the threaded connector 5 are connected.

[0029] Reference Figure 1-3 The rotating mechanism 7 includes a rotating seat 701, which is fixedly installed on the top of the connecting pipe 2. A rotating rod 702 is rotatably connected inside the rotating seat 701. The top of the rotating rod 702 is fixedly installed on the bottom of the C-shaped seat 8. The connecting rod 9 is a telescopic rod. An anti-slip ring 13 is fixedly installed on the inner ring of the limiting ring 10.

[0030] When the fixing ring 4 is connected to the connecting pipe 2, the C-shaped seat 8 is rotated by the rotating rod 702, which facilitates the rotation of the position of the connecting rod 9 and the limiting ring 10 without affecting the connection between the fixing ring 4 and the connecting pipe 2. At the same time, the connecting rod 9 is a telescopic rod, which has a certain degree of tolerance for the position of the rotating handle 6. The limiting ring 10 and the rotating handle 6 can be connected by adjusting the length of the connecting rod 9, which improves the practicality during use. The anti-slip ring 13 increases the anti-slip effect when the limiting ring 10 and the rotating handle 6 are connected, further reducing the possibility of the limiting ring 10 and the rotating handle 6 accidentally separating.

[0031] Reference Figure 4 The spring 11 has a telescopic guide rod 12 inside. The bottom end of the telescopic guide rod 12 is installed on the inner wall of the C-shaped seat 8, and the telescopic end of the telescopic guide rod 12 is installed on the bottom end of the connecting rod 9. The outer surfaces of both the spring 11 and the telescopic guide rod 12 are coated with a waterproof layer. The telescopic guide rod 12 guides the spring 11 during its elastic expansion and contraction, which helps to improve the service life of the spring 11. The waterproof layer reduces the impact of moisture on the spring 11 and the telescopic guide rod 12, reduces the possibility of rust, improves the waterproof effect of the spring 11 and the telescopic guide rod 12, and is conducive to the long-term use of the spring 11 and the telescopic guide rod 12.

[0032] Working principle: The C-shaped seat 8 is rotated by the rotating mechanism 7, and then the fixing ring 4 is connected to the connecting pipe 2 through the threaded connector 5. The rotating handle 6 facilitates the rotation of the threaded connector 5. Rotating the threaded connector 5 keeps the two sets of rotating handles 6 perpendicular. Then, the rotating mechanism 7 rotates the C-shaped seat 8 towards the rotating handle 6, and at the same time, the connecting rod 9 is rotated upward through the C-shaped seat 8. When the limiting ring 10 is directly above the rotating handle 6, the connecting rod 9 can be rotated downward, so that the limiting ring 10 is sleeved on the outer surface of the rotating handle 6, fixing the rotating handle 6. The fixing process for the two sets of rotating handles 6 is the same. At the same time, the spring 11... Under the action, the position of the connecting rod 9 is limited to prevent the connecting rod 9 from rotating automatically. The fixed ring 4 is fixed by the fixed rotation handle 6, which improves the reliability of the connection between the connecting pipe 2 and the water hose 3. When the fixed ring 4 is connected to the connecting pipe 2, the C-shaped seat 8 is rotated by the rotating rod 702, which facilitates the rotation of the position of the connecting rod 9 and the limiting ring 10 without affecting the connection between the fixed ring 4 and the connecting pipe 2. At the same time, since the connecting rod 9 is a telescopic rod, it has a certain degree of tolerance for the position of the rotating handle 6. The limiting ring 10 can be connected to the rotating handle 6 by adjusting the length of the connecting rod 9, which improves the practicality during use.

[0033] Among them, the sealing ring greatly reduces the gap when the connecting pipe 2 and the threaded connector 5 are connected, improving the sealing performance when the connecting pipe 2 and the threaded connector 5 are connected. The telescopic guide rod 12 plays a guiding role when the spring 11 elastically expands and contracts, which helps to improve the service life of the spring 11.

[0034] At the same time, the anti-slip ring 13 increases the anti-slip effect when the limit ring 10 is connected to the rotary handle 6, further reducing the possibility of the limit ring 10 and the rotary handle 6 accidentally separating.

[0035] In addition, the waterproof layer reduces the impact of moisture on the spring 11 and the telescopic guide rod 12, reduces the possibility of rust, improves the waterproof effect of the spring 11 and the telescopic guide rod 12, and is beneficial to the long-term use of the spring 11 and the telescopic guide rod 12.
