Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing technology, specifically a pipeline fixing device for fire protection engineering. Background Technology

[0002] Firefighting equipment is an essential facility in a building and needs to be placed and installed in various places on each floor. In order to contain fires in a timely manner, the laying of fire hydrant pipes is also particularly important. As an important way for firefighters to quickly replenish water, fire hydrant pipes need to be installed and fixed in high places on the floors or in corners at low places that do not affect the normal life of residents.

[0003] In the current field of fire protection engineering, the conventional fire pipe fixing devices widely used have serious functional defects. In actual use, these devices only serve to fix the fire pipes, but cannot display the water status inside the fire pipes at all. It is important to know that in the extremely dangerous emergency of a residential fire, the presence of water in the fire pipes has a crucial impact on firefighting operations and the safety of people's lives. Because the water status cannot be known, firefighters or homeowners may assume there is water in the pipes, only to find that there is no water available after connecting the fire equipment. This could lead to the fire spreading out of control, resulting in significant casualties and property damage. In addition, these traditional fire pipe fixing devices also show obvious deficiencies in maintenance. When the fire pipes are blocked, maintenance personnel cannot obtain any information about the location of the blockage from the fixing devices. This often requires maintenance personnel to spend a lot of time and energy checking along the long pipeline one by one, which greatly increases the difficulty and cost of maintenance. Moreover, this single-function status also limits the overall maintenance efficiency and reliability of the fire protection system, and cannot meet the requirements of modern fire protection for rapid and accurate fault handling, bringing huge potential risks to fire protection work.

[0004] Therefore, this utility model provides a pipe fixing device for fire protection engineering to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a pipe fixing device for fire protection engineering, which solves the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pipe fixing device for fire protection engineering includes a bracket. The bracket is connected to a fixing frame via bolts at its mating position, and is also connected to a wall via the fixing frame and bolts. The bracket includes a first set of rings and a second set of rings. A first secondary ring is integrally formed at the center of the outer ring surface of the first set of rings, and the first secondary ring communicates with the inner ring of the first set of rings by forming a T-shaped water cavity. A pressure relief valve is fixedly connected at the center of the outer ring surface of the first secondary ring, and the pressure relief valve communicates with the water cavity. A second secondary ring is integrally formed at the lower middle position of the outer ring surface of the second set of rings. The interior of the second secondary ring is divided into two spaces of different sizes, wherein the space located on the upper side... The larger space houses a power supply unit for controlling and stabilizing the power supply to the electric actuator. The smaller space below is open at its lower end to form a drainage trough. A valve pipe is connected to the space containing the drainage trough inside the second ring. A valve seat is fixedly installed inside the valve pipe near the port of the inner ring of the second ring. A conical groove is formed inside the valve seat, and a valve body is inserted into the groove. The valve body is slidably confined inside the groove by a spring rod. The top of the valve body passes through the valve seat and is fixed to a valve rod located at the core of the valve pipe. The lower end of the valve rod extends into the drainage trough and is fixed to the input shaft of the electric actuator, which also extends into the drainage trough. The electric actuator is bolted to the surface of the second ring.

[0007] Preferably, the lower end of the first collar is integrally provided with a rotating shaft, and the lower end of the second collar is integrally provided with a rotating ear. The first collar and the second collar are rotatably connected by the hinge formed by the rotating shaft and the rotating ear.

[0008] Preferably, both the first and second rings have an integrally formed fixing lug on the upper side of their sides, and after rotation and docking, they can be installed and fixed on the wall by using the fixing lug and bolts in conjunction with the fixing bracket.

[0009] Preferably, sealing strips are bonded and fixed to the concave surfaces of the first and second collars near the ring opening after assembly. The concave surfaces of the first and second collars are symmetrically provided with mating grooves between the sealing strips along the center for clamping and mating with the fire pipe end, and the mating grooves are circumferentially opened along the inner walls of the first and second collars.

[0010] Preferably, the valve body is gyroscope-shaped and has several through holes on its surface to ensure water flow.

[0011] Beneficial effects

[0012] This utility model provides a pipe fixing device for fire protection engineering. Compared with the prior art, it has the following advantages:

[0013] (1) In daily use, the pipe fixing device used in fire protection engineering allows water from the fire protection pipeline to enter the water chamber of the first ring after water is supplied. The power supply unit in the second ring, under the control of the control components, periodically supplies power to the electric actuator, causing the actuator to push the valve stem and move the valve body. This allows water from the fire protection pipeline to drain through the through-hole, valve seat, and valve pipe on the valve body into the drainage trough. Then, the electric actuator pulls the valve body back to its original position, closing the valve seat. This continuous cycle visually demonstrates that the fire protection pipeline is in a water-supply state, allowing owners and property management to stay informed and avoiding the embarrassing situation of having no water available during a disaster. This greatly improves the reliability and timeliness of firefighting operations, ensuring the safety of people and property.

[0014] (2) When the pipeline is blocked, the water pressure inside the first and second rings near the blocking position increases, and the water pressure in the water chamber increases accordingly. When the water pressure reaches the pressure relief valve, the pressure relief valve opens to release water. Pipeline maintenance personnel can quickly determine the blocking position based on the water release position, thereby carrying out precise maintenance. Compared with traditional fixing devices, this greatly reduces the time and effort required to find the blocking position, improves the efficiency of fire pipeline maintenance, reduces maintenance costs, enhances the overall reliability and stability of the fire system, and ensures that the fire pipeline can operate normally at critical moments.

[0020] 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.

[0021] Example 1:

[0022] Please see Figure 1-4 A pipe fixing device for fire protection engineering includes a bracket 1. The bracket 1 is bolted to a fixing frame 2, and the fixing frame 2 is bolted to a wall. The bracket 1 includes a first collar 11 and a second collar 12. The lower end of the first collar 11 is integrally provided with a rotating shaft, and the lower end of the second collar 12 is integrally provided with a rotating lug. The first collar 11 and the second collar 12 are rotatably connected by a hinge 14 formed by the rotating shaft and the rotating lug. A fixing lug 13 is integrally provided on the upper side of both the first collar 11 and the second collar 12. After rotational connection, the fixing lug 13 and bolts, together with the fixing frame 2, allow for installation and fixing on the wall. Sealing strips 15 are glued and fixed to the concave surfaces near the joint of the rings. The concave surfaces of the first ring 11 and the second ring 12 are symmetrically provided with mating grooves between the sealing strips 15 along the center for clamping and mating with the fire pipe end. The mating grooves are circumferentially opened along the inner walls of the first ring 11 and the second ring 12. A first secondary ring 111 is integrally provided at the center of the outer ring surface of the first ring 11. A T-shaped water cavity 113 is provided in connection with the inner ring of the first ring 11. A pressure relief valve 112 is fixedly provided at the center of the outer ring surface of the first secondary ring 111. The pressure relief valve 112 is interconnected with the water cavity 113 and the water cavity 113 is used to relieve pressure at the sealed position inside the fire pipe.

[0023] After the fire pipeline is energized, the water inside will enter the first secondary ring 111 through the water chamber 113. Under the control of the control component, the second secondary ring 121 will periodically supply power to the electric actuator 126. The electric actuator 126 will then push the valve stem 125 to move through the output shaft. The moving valve stem 125 will cause the valve body 123 to slide upward in the conical groove of the valve seat 127, compressing the spring rod 124 and gradually changing the open area between the valve seat 127 and the valve body 123. Then, the water inside the fire pipeline will enter the valve pipe 122 through the through hole on the valve body 123, through the valve seat 127, and then enter the interior of the drain trough 1212 along the valve pipe 122. Finally, it will be discharged from the drain trough 1212. After a specified time, the electric actuator 126 will pull the valve stem 125 and the valve body 123 to reset, and close the valve seat 127 again. This process will continue during use, so that the owner and property management can know that the fire pipeline is in a water-energized state.

[0024] In summary, during daily use, water from the fire-fighting pipeline enters the water chamber 113 of the first ring 11. The power supply unit 1211 in the second ring 12, under the control of the control components, periodically supplies power to the electric actuator 126. This causes the electric actuator 126 to push the valve stem 125, which in turn moves the valve body 123. Water from the fire-fighting pipeline then flows through the through-hole on the valve body 123, the valve seat 127, and the valve pipe 122 into the drain trough 1212 and is discharged. The electric actuator 126 then pulls the valve body 123 back to its original position, closing the valve seat 127. This continuous cycle clearly demonstrates that the fire-fighting pipeline is in a water-filled state, allowing owners and property management to stay informed and avoiding the embarrassing situation of having no water available during a disaster. This significantly improves the reliability and timeliness of fire-fighting operations, ensuring the safety of people and property.

[0025] Example 2:

[0026] Please see Figure 1 , Figure 2 and Figure 4This embodiment provides a technical solution based on Embodiment 1: A second auxiliary ring 121 is integrally provided at the lower middle position of the outer ring surface of the second ring 12. The interior of the second auxiliary ring 121 is divided into two spaces of different sizes. The larger upper space is provided with a power supply unit 1211 for controlling and stabilizing the power supply to the electric actuator 126. The smaller lower space is opened at its lower end as a drainage channel 1212. A valve pipe 122 is provided inside the second ring 12 and communicates with the space where the drainage channel 1212 is located. The valve pipe 122 is fixedly installed inside the second ring 12 at a position near the port of the inner ring surface of the second ring 12. There is a valve seat 127, and a conical groove is opened inside the valve seat 127. The valve body 123 is inserted into the groove and is slidably limited inside the groove by a spring rod 124. The valve body 123 is gyroscope-shaped and has several through holes on its surface to ensure water flow. The top of the valve body 123 passes through the valve seat 127 and is fixed to the valve rod 125 located at the core of the valve tube 122. The lower end of the valve rod 125 extends into the interior of the drain groove 1212 and is fixed to the input shaft of the electric actuator 126, which also extends into the drain groove 1212. The electric actuator 126 is bolted to the surface of the second auxiliary ring 121.

[0027] If a fire pipeline becomes blocked, the water pressure inside the first ring 11 and the second ring 12 near the blockage will increase, and then the water pressure inside the water chamber 113 will also increase. As the blockage continues and the water pressure continues to increase, the water pressure will reach the condition for the pressure relief valve 112 to release pressure. Then the pressure relief valve 112 will open to release the water that has entered the water chamber 113. Then, pipeline personnel can determine the location of the blockage based on the location of the water release, so as to carry out precise maintenance of the fire pipeline and reduce the maintenance time of the fire pipeline.

[0028] In summary, when the pipeline is blocked, the water pressure inside the first ring 11 and the second ring 12 near the blocking position increases, and the water pressure in the water chamber 113 increases accordingly. When the water pressure reaches the pressure relief valve 112, the pressure relief valve 112 opens to release water. Pipeline maintenance personnel can quickly determine the blocking position based on the water release location, thereby performing precise maintenance. Compared with traditional fixed devices, this greatly reduces the time and effort required to locate the blocking position, improves the efficiency of fire pipeline maintenance, reduces maintenance costs, enhances the overall reliability and stability of the fire protection system, and ensures that the fire pipeline can operate normally at critical moments.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: During installation, the first set of rings 11 and the second set of rings 12 are rotated and connected via the hinge 14 formed by the rotating shaft and the rotating lug, so that the connecting groove surrounds the end of the fire pipe (there will be a certain gap at the pipe end). Then, the device is installed on the wall using the fixing lug 13 and bolts in conjunction with the fixing bracket 2 (e.g., Figure 1 As shown), at this time, the sealing strip 15 is tightly attached to the surface of the fire pipe to ensure the sealing of the connection between the device and the fire pipe, thereby realizing the connection between the device and the fire pipe and the fixing of the fire pipe; after the installation is completed, the fire pipe can be used normally. After the water is turned on, the water inside the fire pipe will enter the interior of the first auxiliary ring 111 through the water chamber 113, while the second auxiliary ring 121 will supply power to the electric actuator 126 at regular intervals under the control of the control component. Then the electric actuator 126 will push the valve rod 125 to move through the output shaft. The moving valve rod 125 will drive the valve body 123 to slide upward in the conical groove of the valve seat 127, compressing the spring rod 124 and gradually changing the open area between the valve seat 127 and the valve body 123. Then the water inside the fire pipe will enter the valve pipe 122 through the through hole on the valve body 123 and the valve seat 127, and then flow along the valve pipe 122. Water enters the interior of the drainage trough 1212 and is eventually discharged (a small amount of water). After a specified time, the electric actuator 126 will pull the valve stem 125 and valve body 123 to reset, and close the valve seat 127 again. This process will continue during use, so that owners and property management can know whether the fire pipeline is in a water-filled state. If the fire pipeline is blocked, the water pressure inside the first ring 11 and the second ring 12 near the blockage position will increase, and then the water pressure inside the water chamber 113 will increase. As the blockage continues and the water pressure continues to increase, the water pressure will reach the condition for the pressure relief valve 112 to release pressure. Then the pressure relief valve 112 will open to release the water entering the water chamber 113. Then, pipeline personnel can determine the blockage position based on the location of the water discharge, so as to carry out precise maintenance of the fire pipeline and reduce the maintenance time of the fire pipeline.
