Abstract
Description
Technical Field
[0001] This application relates to the technical field of pier fire protection, and particularly to a pier fire protection device and a bridge support system. Background Art
[0002] Bridges are essential architectural structures in the fields of infrastructure construction such as highways, railways, and waterways. They are an important part of transportation, carrying a large number of vehicles and pedestrians. Piers are key structures that support bridges. Due to being exposed to the natural environment all year round and the traffic pressure they bear, these structures face various safety hazards, including the risk of fire. When a fire occurs in a pier, it usually starts at the pier and spreads upward to the bridge. This may cause direct damage to the bridge structure, such as a reduction in material strength and local deformation. If the fire cannot be stopped in a timely and effective manner, it may even lead to the collapse of the bridge, triggering more serious safety accidents. Therefore, the early detection of pier fires and timely response measures are particularly important.
[0003] Currently, most of the existing bridge fire monitoring and protection systems adopt traditional manual monitoring and simple alarm mechanisms. The detection system often relies on manual discovery of fires, with a long response time, which is prone to missed alarms and false alarms. In addition, the existing methods for extinguishing pier fires usually require external intervention and cannot quickly and effectively carry out irrigation or isolation measures, resulting in the inability to control the fire source in a timely manner at the initial stage of the fire, thereby increasing the risk of bridge damage. For the problem that the fire source in the early stage of pier fires cannot be quickly detected and isolated, no effective solution has been proposed yet. Summary of the Invention
[0004] In the present invention, a pier fire protection device and a bridge support system are provided to solve the problem that the fire source in the early stage of pier fires cannot be quickly detected and isolated.
[0005] In a first aspect, the present invention provides a pier fire protection device, including:

The brake pad is parallel to the annular double track, and the signal processing system controls the relative fixation of the I-shaped connecting frame and the annular double track through the controllable telescopic rod.
[0013] In some embodiments thereof, the isolation assembly includes a horizontal isolation assembly. The horizontal isolation assembly includes a horizontal fire curtain and a pair of isolation driving members. The deployment of the isolation assembly includes the deployment of the horizontal fire curtain. Each isolation driving member includes a horizontal telescopic rod. The two ends of the first side of the horizontal fire curtain are respectively fixedly connected to the fixed ends of the two horizontal telescopic rods, and the two ends of the second side of the horizontal fire curtain are respectively fixedly connected to the movable ends of the two horizontal telescopic rods. The fixed ends of the horizontal telescopic rods are relatively fixed to the I-shaped connecting frame, and the signal processing system controls the horizontal telescopic rods to extend to achieve the deployment of the horizontal fire curtain.
[0014] In some embodiments thereof, the horizontal telescopic rod is an electric telescopic rod;
[0015] Alternatively, the horizontal telescopic rod is a non-electric telescopic rod. The isolation driving member further includes an installation bin, a second servo motor, two driving wheels, and a tape steel belt. The installation bin is fixedly mounted on the I-shaped connecting frame. The fixed end of the horizontal telescopic rod is fixedly connected to the surface of the installation bin. A first rotating shaft is rotatably mounted on the inner wall of the installation bin. The tape steel belt is wound around the first rotating shaft. The outer end of the tape steel belt extends into the horizontal telescopic rod and is fixedly connected to the movable end of the horizontal telescopic rod. The two driving wheels are both rotatably mounted on the inner wall of the installation bin and are respectively pressed against the two surfaces of the tape steel belt. The second servo motor is fixedly mounted on the inner wall of the installation bin and the output shaft is coaxially fixed to one of the driving wheels.
[0016] In some of these embodiments, the isolation component further includes a vertical isolation component, which includes a vertical fire curtain, a second rotating shaft, and a third servo motor. The unfolding of the isolation component further includes the unfolding of the vertical fire curtain. The second rotating shaft is rotatably installed on the I-shaped connecting frame.

The third servo motor is fixedly installed on the I-shaped connecting frame. The output end of the third servo motor is coaxially fixed to the second rotating shaft. The signal processing system rotates the second rotating shaft to realize the unfolding of the vertical fire curtain.
[0017] In some of these embodiments, the included angle formed between the two horizontal telescopic rods is 60 degrees. The length of the vertical fire curtain is greater than the height of the annular double track. The width of the vertical fire curtain is at least greater than the detection range of one flame composite detector in the horizontal direction.
[0018] In some of these embodiments, the materials of both the vertical fire curtain and the horizontal fire curtain are glass fiber, and the materials of both the I-shaped connecting frame and the second rotating shaft are rubber.

[0021] Compared with the related art, the present invention has the following beneficial effects:
[0022] 1. Multiple flame composite detectors can detect the temperature at various places around the bridge pier in real time and send temperature data to the signal processing system. Once a fire occurs at a certain place around the bridge pier, the highest temperature data detected by the flame composite detector closest to it will exceed the danger threshold. After the signal processing system detects it, it will quickly determine the target flame composite detector providing the highest temperature data and activate the flame isolation mechanism, which can quickly detect the occurrence of the fire. And in this process, the signal processing system will send corresponding electrical signals to the double roller assembly and the isolation component respectively. The double roller assembly first moves the isolation component along the annular double track to directly above the target flame composite detector, and then the isolation component unfolds to isolate the flame, solving the problem that the fire source cannot be quickly detected and isolated in the early stage of the bridge pier fire, and reducing the risk of bridge damage.
[0023] 2. Further, during the deployment of the isolation component, the vertical fire curtain in the isolation component will deploy vertically downward to protect the surface of the pier from fire, and the horizontal fire curtain in the isolation component will deploy horizontally to protect the bottom of the bridge from fire. It can not only protect the surface of the pier, but also take into account the protection of the bottom of the bridge, improving the protection range of the bridge.

[0033] Referring to Figure 1 As shown, in this embodiment, a pier fire protection device is provided, which includes an annular double track 1, a flame composite detector 4, a flame isolation mechanism, a signal processing system 26, a fixing component and an auxiliary roller 27.
[0034] The annular double track 1 is horizontally arranged and fixedly installed on the surface of the pier. The annular double track 1 is divided into an upper track and a lower track. The cross-sections of the upper track and the lower track are both rectangular and there is a certain distance between them. Communication ports are provided on the facing surfaces of the upper track and the lower track to install the flame isolation structure.
[0035] A plurality of flame composite detectors 4 are all fixedly installed on the surface of the pier. They are located directly below the annular double track 1 and are horizontally evenly distributed. Each flame composite detector 4 can detect the temperature at each location within its detection range in real time. The detection range of the flame composite detector 4 is a downward conical range. The plurality of detection ranges overlap in the horizontal direction to cover the circumference of the pier, that is, any angle on the circumference of the pier is covered by the detection range of at least one flame composite detector 4.
[0036] The flame isolation mechanism includes a double-roller assembly 2 and an isolation assembly 3. The double-roller assembly 2 is rotatably installed within an annular double track 1 and can move directly above any flame composite detector 4. The isolation assembly 3 is installed on the double-roller assembly 2 and is used to isolate the flame after being deployed.
[0037] The signal processing system 26 is configured to receive the temperature data transmitted by each flame composite detector 4. When the highest temperature data exceeds the danger threshold, it determines the target flame composite detector 4 that provides the highest temperature data, and controls the double-roller assembly 2 to move directly above the target flame composite detector 4 and controls the isolation assembly 3 to deploy.
[0038] Referring Figure 2 and Figure 3 As shown in the figure, in this embodiment, the double-roller assembly 2 includes four rollers, a first servo motor 23, and an I-shaped connecting frame 25. The four rollers are respectively rotatably installed at the four ends of the I-shaped connecting frame 25 and are in the same rolling plane. The four rollers are divided into a pair of first rollers 21 and a pair of second rollers 22. The four rollers are in rolling contact with the upper and lower tracks of the annular double track 1 in pairs. The two first rollers 21 are respectively rotatably installed at both ends of the first head of the I-shaped connecting frame 25 through auxiliary rotating shafts, and the two second rollers 22 are also respectively rotatably installed at both ends of the second head of the I-shaped connecting frame 25 through auxiliary rotating shafts. Multiple auxiliary rotating shafts are perpendicular to the surface of the bridge pier. The I-shaped connecting frame 25 is located at the interval between the upper track and the lower track, and its four ends respectively penetrate into two communication ports. The signal processing system 26 is installed on the I-shaped connecting frame 25. The signal processing system 26 is electrically connected to the first servo motor 23. The output shaft of the first servo motor 23 is coaxially fixed to the auxiliary rotating shaft on the first roller 21. The signal processing system 26 controls the rotation of the rollers through the first servo motor 23 to achieve the movement of the double-roller assembly 2. When the double-roller assembly 2 needs to move, the signal processing system 26 controls the rotation of the auxiliary rotating shaft by sending corresponding electrical signals to the first servo motor 23, thereby driving the rotation of the first roller 21, and finally giving the double-roller assembly 2 sufficient power to move it along the annular track 1.
[0039] Further, to enhance the stability of the double-roller assembly 2, the double-roller assembly 2 further includes at least one fixing member. Each fixing member includes a controllable telescopic rod 24 and a brake pad 28. The fixed end of the controllable telescopic rod 24 is fixedly installed at either end of the I-shaped connecting frame 25, and the movable end is fixedly connected to the brake pad 28. The brake pad 28 is parallel to the annular double track 1. The signal processing system 26 is electrically connected to the controllable telescopic rod 24. The signal processing system 26 controls the telescopic movement of the controllable telescopic rod 24 to manipulate the contact between the brake pad 28 and the annular double track 1, thereby quickly decelerating and fixing the I-shaped connecting frame 25 relative to the annular double track 1. Exemplarily, the double-roller assembly 2 further includes a plurality of auxiliary rollers 27. The plurality of auxiliary rollers 27 are all rotatably installed on the I-shaped connecting frame 25. The plurality of auxiliary rollers 27 are all in rolling contact with the surface of the bridge pier. The presence of the auxiliary rollers 27 can prevent the I-shaped connecting frame 25 from rubbing against the surface of the bridge pier, and when the double-roller assembly 2 passes through a bend on the annular double track 1, the auxiliary rollers 27 can provide a certain supporting force to the double-roller assembly 2.
[0040] Refer to Figure 1 and Figure 4As shown, in this embodiment, the isolation component 3 includes a horizontal isolation component. The horizontal isolation component includes a horizontal fire curtain 6 and a pair of isolation driving components. The deployment of the isolation component 3 includes the deployment of the horizontal fire curtain 6. Each isolation driving component includes a horizontal telescopic rod 34. The two ends of the first side of the horizontal fire curtain 6 are respectively fixedly connected to the fixed ends of the two horizontal telescopic rods 34, and the two ends of the second side of the horizontal fire curtain 6 are respectively fixedly connected to the moving ends of the two horizontal telescopic rods 34. The fixed ends of the two horizontal telescopic rods 34 are respectively fixedly installed at both ends of the I-shaped connecting frame 25, and their moving ends can extend and deploy from the gap between the upper track and the lower track. The signal processing system 26 is electrically connected to the horizontal telescopic rod 34. The signal processing system 26 realizes the deployment of the horizontal fire curtain 6 by controlling the elongation of the horizontal telescopic rod 34. Before the horizontal fire curtain 6 is deployed, it contracts in the I-shaped connecting frame 25 together with the horizontal telescopic rod 34. When the horizontal isolation component needs to be deployed, the signal processing system 26 can send corresponding electrical signals to control the elongation of the two horizontal telescopic rods 34, and the horizontal fire curtain 6 will deploy together with the two horizontal telescopic rods 34. Further, the horizontal telescopic rod 34 is an electric telescopic rod and includes its own power source; or, the horizontal telescopic rod 34 is a non-electric telescopic rod, and the isolation driving component further includes an installation bin, a second servo motor 31, two driving wheels 32, and a tape steel belt 33. The installation bin is fixedly installed on the I-shaped connecting frame 25. The fixed end of the horizontal telescopic rod 34 is fixedly connected to the surface of the installation bin. A first rotating shaft is rotatably installed on the inner wall of the installation bin. The tape steel belt 33 is wound around the first rotating shaft. The outer end of the tape steel belt 33 extends into the horizontal telescopic rod 34 and is fixedly connected to the moving end of the horizontal telescopic rod 34. The two driving wheels 32 are both rotatably installed on the inner wall of the installation bin and are respectively pressed against the two surfaces of the tape steel belt 33. The rolling channel formed by the two driving wheels 32 is in the same horizontal plane as the horizontal telescopic rod 34. The second servo motor 31 is fixedly installed on the inner wall of the installation bin and the output shaft is coaxially fixed to one of the driving wheels 32. The second servo motor 31 is electrically connected to the signal processing system 26. If the horizontal telescopic rod 34 itself does not contain a power source, the signal processing system 26 can send corresponding electrical signals to control the second servo motor to drive the driving wheel 32 to rotate. The driving wheel 32 can drive the outer end of the tape steel belt 33 to elongate through friction, and finally drive the moving end of the horizontal telescopic rod 34 to elongate.
[0041] Referring to Figure 1As shown in the figure, in this embodiment, the isolation component 3 further includes a vertical isolation component, which includes a vertical fire curtain 5, a second rotating shaft, and a third servo motor. The deployment of the isolation component 3 further includes the deployment of the vertical fire curtain 5. The second rotating shaft is rotatably installed on the I-shaped connecting frame 25. The second rotating shaft is horizontally arranged and perpendicular to the auxiliary rotating shaft. The second rotating shaft is located in the middle of the I-shaped connecting frame 25. The vertical fire curtain 5 is wound around the second rotating shaft. The third servo motor is fixedly installed on the I-shaped connecting frame 25. The output end of the third servo motor is coaxially fixed to the second rotating shaft. The signal processing system 26 realizes the deployment of the vertical fire curtain 5 by controlling the rotation of the second rotating shaft. When it is necessary to deploy the vertical fire curtain 5, the signal processing system 26 controls the rotation of the second rotating shaft by sending corresponding electrical signals to the third servo motor. Under the action of gravity, the outer end of the vertical fire curtain 5 will slowly extend downward and unfold. Similarly, when it is necessary to retract, the second rotating shaft can also be controlled to rotate in reverse, so as to roll the vertical fire curtain 5 back onto the second rotating shaft again.
[0042] Further, the included angle formed between the two horizontal telescopic rods 34 is 60 degrees. When installing the two horizontal telescopic rods 34 on the I-shaped connecting frame 25, the included angle between them is set to be approximately 60 degrees, so that the deployed horizontal fire curtain 6 forms a fan-shaped protection range, reasonably planning the laying area of the horizontal fire curtain 6, which is beneficial to saving production materials. The length of the vertical fire curtain 5 is greater than the height of the annular double track 1, and the width of the vertical fire curtain 5 is at least greater than the detection range of a flame composite detector 4 in the horizontal direction. In order to effectively isolate the flame, when the outer end of the vertical fire curtain 5 fully extends, its length needs to be greater than the height of the annular double track 1, and a fire has a certain range. It is possible that multiple adjacent flame composite detectors 4 also detect the same maximum temperature at the same time. At this time, because the width of the vertical fire curtain 5 is at least greater than the detection range of a flame composite detector 4 in the horizontal direction, no matter which flame composite detector 4 the double roller assembly 2 moves to, the flame can be effectively isolated. Exemplarily, the materials of the vertical fire curtain 5 and the horizontal fire curtain 5 are both fiberglass, and the materials of the I-shaped connecting frame 25 and the second rotating shaft are rubber. Fiberglass can remain stable at extremely high temperatures, with a long-term service temperature of up to 500 °C or more and an instantaneous temperature resistance of up to 800 °C, which can effectively isolate the flame to protect the bridge pier. When the double roller assembly 2 passes through the bend of the annular double track 1, due to the extrusion of the bridge pier surface, both the I-shaped connecting frame 25 and the second rotating shaft will deform. Therefore, a deformable rubber material is used for production.
[0043] To sum up, referring to Figure 5As shown, multiple flame composite detectors 4 can detect the temperature at various locations around the bridge pier in real time and send temperature data to the signal processing system 26. Once a fire breaks out at a certain location around the bridge pier, the highest temperature data detected by the flame composite detector 4 closest to it will exceed the danger threshold. After the signal processing system 26 detects this, it will quickly determine the target flame composite detector 4 that provides the highest temperature data and activate the flame isolation mechanism, which can quickly detect the occurrence of a fire. During this process, the signal processing system 26 will respectively send corresponding electrical signals to the double-roller assembly 2 and the isolation assembly 3. The double-roller assembly 2 first moves the isolation assembly 3 along the annular double track 1 to directly above the target flame composite detector 4, and then the isolation assembly 3 unfolds to isolate the flame, solving the problem that the fire source cannot be quickly detected and isolated in the early stage of bridge pier fire and reducing the risk of bridge damage.
[0044] Furthermore, during the unfolding process of the isolation assembly 3, the vertical fire curtain in the isolation assembly 3 will unfold vertically downward to protect the surface of the bridge pier from the impact of the fire, and the horizontal fire curtain in the isolation assembly 3 will unfold horizontally to protect the bottom of the bridge from the impact of the fire. It can not only protect the surface of the bridge pier, but also take into account the protection of the bottom of the bridge, improving the protection range of the bridge.
[0045] In this embodiment, a bridge support system is also provided, which includes the bridge pier fire protection device provided in this embodiment and the bridge pier, and the bridge pier fire protection device is installed on the bridge pier.
[0046] The bridge pier fire protection device can quickly detect the occurrence of a fire through the cooperation of the flame composite detector 4 and the signal processing system 26, and then isolate the flame through the flame isolation mechanism, reducing the risk of bridge damage. The bridge support system includes the bridge pier fire protection device provided in this embodiment and the bridge pier, and the bridge pier fire protection device is installed on the bridge pier. Using this bridge support system can reduce the risk of its own damage.
