Description

Technical Field

[0001] The invention relates to the technical field of electronic information, in particular to a split-line alarm controller which is convenient to install and disassemble. Background Art

[0002] The branch-line alarm controller is a device widely used in the field of security protection. It is mainly used to receive, process and display alarm signals from various detectors. It is usually composed of an alarm control host, detectors and signal lines connecting the two. There are many types of branch-line alarms, common ones include: combustible gas branch-line alarms, smoke alarms, temperature alarms, etc. Among them, combustible gas alarms are used to detect leaks of combustible gases, such as natural gas, liquefied petroleum gas, hydrogen and other combustible gases.

[0003] In the prior art, when the combustible gas alarm uses a split-line system, the signal of each detector has its own dedicated transmission channel. When in use, different detectors are connected to the alarm mainboard to detect the combustible gas in the use environment for feedback. However, as the functions of the alarm become increasingly complex, the number of connected lines gradually increases. When the lines lack guidance in the middle, they are easily entangled and knotted, which not only affects the appearance, but more seriously causes interference between signals, affecting the accuracy of combustible gas concentration detection. In some places with extremely high safety requirements, such as chemical plants, gas stations, etc., inaccurate detection signals can cause serious safety accidents.

[0004] Secondly, the traditional connection method lacks flexibility for different numbers of detectors and their cables. When installing, maintaining, replacing cables or adding or reducing detectors, the confusion of lines makes it difficult for installers to connect the lines quickly and accurately, increasing the installation time and difficulty. Once the installation is completed, if a line fault occurs, it is difficult to untangle the entangled lines, and it is difficult for maintenance personnel to quickly locate the fault point. It is often necessary to dismantle the entire cable system on a large scale. The operation is cumbersome, time-consuming and costly, and has a great impact on the normal operation of the equipment. A lot of time has to be spent on investigation and repair, which not only affects production efficiency, but also causes signal interference, affecting the performance of the alarm system, resulting in the risk of combustible gas leaks not being detected and alarmed in time during maintenance.

[0005] Therefore, a split-line alarm controller which is easy to install and disassemble is proposed to solve the above problems. Summary of the invention

[0015] Preferably, the arc-shaped plate is made of rubber.

[0016] Compared with the prior art, the present invention provides a split-line alarm controller that is easy to install and disassemble, and has the following beneficial effects:

[0017] 1. Through the setting of the cable storage and installation mechanism, under the action of the forward and reverse rotation of the control screw rod, the threaded plug is driven to move on the control screw rod, thereby adjusting the spacing between the assemblies. After the detector cables are stored in the arc plate, the cables are installed in a specific position in an orderly manner. When the spacing shrinks, the clamping mechanism is pushed to clamp and fix the cables, avoiding the disorder of the cables, making the cable management more standardized, reducing the risk of misoperation and failure caused by cable confusion, and ensuring the relative position between the detectors is stable. In an environment affected by vibration or external force, the stable spacing helps to reduce the displacement between the detectors, thereby ensuring the reliability of the cable connection, preventing the adverse effects of the detector position change on the cable connection, and improving the stability of the entire alarm system. At the same time, the orderly cable layout also facilitates the rapid positioning of the fault point and shortens the troubleshooting time.

[0018] 2. Furthermore, the coordinated use of the snap-on buckle and the arc block assists the installation and removal of the U-shaped body and the assembly, and the installation and removal design of the clamping structure is carried out according to the number of cables, which improves the flexibility of installation and removal. In the actual installation and use process, the installer can flexibly choose the number and position of the matching regular positioning mechanism according to the specific number and layout of the detectors and their cables, and quickly complete the installation work. When equipment maintenance, cable replacement or adding or reducing detectors is required, it can be easily disassembled without large-scale disassembly of the entire cable system, saving maintenance time and cost, and reducing the impact on the normal operation of the equipment.

[0019] 3. Through the setting of the adaptive regular positioning mechanism, when the positioning body moves closer on the slide rail, the adapter spring makes the arc plate align and close to the storage cable. This kind of cable regulation and fixing effect helps to maintain the stability of the cable connection, thereby ensuring the accurate transmission of data. The cooperation of the slide rail, the positioning body, the arc plate and other structures can organize the cables of the same detector into the same group of arc plates for storage. The regular cable layout effectively avoids the disorderly distribution of cables, thereby preventing signal interference caused by the mixing of cables between different detectors, such as poor signal coupling, thereby reducing false alarms or inaccurate alarms, and improving the accuracy and reliability of the alarm system. With the help of the adapter spring, the arc plate can be adaptively adjusted according to cables of different thicknesses, so that cables of various specifications can be properly fixed. This function of adapting to cables of different thicknesses can not only meet the fixing requirements of different detector cables, but also makes it easier to locate the fault of separately stored cables. By checking the cables of specific detectors, the scope of troubleshooting can be quickly narrowed, the efficiency of troubleshooting can be improved, and it is more conducive to subsequent maintenance and repair work. The stable cable connection can ensure the accurate transmission of combustible gas detection data and avoid false alarms or data loss due to loose cables or poor contact.

[0040] For further examples, please refer to Figures 5 to 9 As shown:

[0041] The adaptable regular positioning mechanism 3 is used to clamp and organize the cables during the storage process to avoid the cables from being scattered and to adapt to cables of different thicknesses. The adaptable regular positioning mechanism 3 includes a slide rail 31. The slide rail 31 is mainly used to assist the horizontal movement of the positioning body 36. The slide rail 31 is fixedly connected to the U-shaped body 210. A groove 32 is opened in the middle of the slide rail 31. A linkage bar 33 is rotatably connected to the groove 32. Fixed plates 34 are rotatably connected to both ends of the linkage bar 33. Reset torsion springs 35 are fixedly connected between the linkage bar 33 and the fixed plates 34. The ends of the two fixed plates 34 away from the linkage bar 33 are fixedly connected to the positioning body 36. The positioning body 36 is slidably connected to the slide rail 31. The two sides of the middle of the positioning body 36 are slidably connected A slide bar 37 is connected, and the slide bar 37 is mainly used to assist the stability of the centering movement of the positioning body 36. A buffer spring 38 is provided on the outer ring of the slide bar 37. The two ends of the buffer spring 38 are respectively fixedly connected to the two positioning bodies 36. An adapter spring 39 is fixedly connected to the middle of the adjacent side of the positioning body 36, and an arc plate 310 is fixedly connected to the end of the adapter spring 39 away from the positioning body 36. The arc plate 310 is mainly used to cooperate with the adapter spring 39 to perform regular operations on cables of different thicknesses. The arc plate 310 is made of rubber. The two positioning bodies 36 are fixedly connected to a resistance rod 311 on one side away from the slide bar 37. The resistance rod 311 is mainly used to resist each other and then push the positioning body 36 to position the cable after the centering displacement.

[0042] Everything in the above example works like this:

[0043] In the initial state: the detector cable is not connected to the main board 11 , the built-in power supply of the L-shaped positioning block 21 is not started to drive the control screw 23 to rotate, there is a distance between the assemblies 24 , and the abutment rods 311 do not abut each other.

[0044] The following is the working process of the cable storage and installation mechanism 2 which realizes the effective storage of different detector cables and can flexibly adjust and install the installation and removal operation according to the specific number of detector cables during the process of connecting the detector and the alarm mainboard:

[0045] When in use, after multiple combustible gas detectors are installed, the cables are inserted into the box body 1 through the gathering hole 12, and then the cables of the same detector are passed through a group of arc plates 310 according to the type of detector, and the cables are initially stored to regularly distinguish the cables of multiple detectors, and then the other end of the cable is connected to the main board 11. When the external detector detects combustible gas, the detected abnormal situation is converted into an electrical signal and sent to the main board 11. The main board 11 receives the alarm signal from each detector and issues a warning. After each detector is stored in each group of arc plates 310 according to the distinction, the built-in power supply of the L-shaped positioning block 21 is started, and the output end drives the control screw 23 to rotate forward When the control screw 23 rotates forward, the threaded plug 26 is connected to the control screw 23 through the threaded connection, driving the threaded plug 26 to move toward one end of the large L-shaped block on the control screw 23, and under the movement of the threaded plug 26, the assembly 24 synchronously slides toward one end of the large L-shaped block through the threaded plug 26, and the horizontal movement is ensured with the assistance of the guide rod 22, and the assemblies 24 are further connected by the connecting rod 25. Therefore, when the threaded plug 26 drives the assembly 24 at one end to move, the other assemblies 24 sliding on the guide rod 22 are all moved closer to each other on the guide rod 22 through the deflection of the connecting rod 25, so that the cables scattered in the arc plate 310 are stored close to each other to avoid the cables from being entangled and knotted;

[0046] On the basis of the above, the U-shaped body 210 clamped on the assembly 24 can be installed and removed according to the number of detectors installed. When installing the U-shaped body 210, align the U-shaped body 210 with the assembly 24 and then move it toward the assembly 24. The snap-fit ​​buckles 211 at both ends of the U-shaped body 210 simultaneously approach the assembly 24. Then, with the assistance of the installation and removal cavities 27 at both ends of the assembly 24, the snap-fit ​​buckles 211 gradually approach the arc block 28 in the installation and removal cavity 27. Under the action of the arc surface of the snap-fit ​​buckle 211, the arc block 28 is gradually resisted from deviating to both sides, causing the auxiliary spring 29 to contract. Then, when the snap-fit ​​buckle 211 continues to push, the snap-fit ​​buckle 211 is clamped into the arc block 28. Under the action of the restoring force of the auxiliary spring 29, the arc block 28 is pushed to recover and the snap-fit ​​buckle 211 is clamped in the two arc blocks 28, thereby completing the installation and removal of the assembly 24 and the installation and removal cavity 27.

[0047] By setting the cable storage and installation mechanism 2, under the action of the forward and reverse rotation of the control screw 23, the threaded plug 26 is driven to move on the control screw 23, thereby adjusting the spacing between the assemblies 24. After the detector cables are stored in the arc plate 310, the cables are installed in a specific position in an orderly manner. When the spacing shrinks, the clamping mechanism is pushed to clamp and fix the cables, thereby avoiding the disorder of the cables, making the cable management more standardized, reducing the risk of misoperation and failure caused by cable confusion, and ensuring the relative position between the detectors is stable. In an environment affected by vibration or external force, the stable spacing helps to reduce the displacement between the detectors, thereby ensuring the reliability of the cable connection, preventing the adverse effects of the detector position change on the cable connection, and improving the stability of the entire alarm system. At the same time, the orderly cable layout also facilitates the rapid positioning of the fault point and shortens the troubleshooting time.

[0048] Furthermore, with the coordinated use of the snap-fit ​​buckle 211 and the arc block 28, the installation and removal of the U-shaped body 210 and the assembly 24 are assisted, and the installation and removal design of the clamping structure is carried out according to the number of cables, thereby improving the flexibility of installation and removal. In the actual installation and use process, the installer can flexibly choose the number and position of the matching regular positioning mechanism 3 according to the specific number and layout of the detectors and their cables, and quickly complete the installation work. When equipment maintenance, cable replacement or adding or reducing detectors is required, it can be conveniently disassembled without large-scale disassembly of the entire cable system, saving maintenance time and cost, and reducing the impact on the normal operation of the equipment.

[0049] Please refer to the above working process Figures 1 to 6 .

[0050] The following is the working process of the adapting and aligning positioning mechanism 3 for clamping and aligning the cables to avoid the cables being scattered and adapting to cables of different thicknesses during storage:

[0051] When in use, according to the above-mentioned movement process, the rotation of the control screw 23 drives the multiple assemblies 24 to approach each other. Since the U-shaped body 210 is installed on the assemblies 24, when the assemblies 24 approach each other, the U-shaped bodies 210 move synchronously to each other. Then, in the process of the U-shaped body 210 approaching, the interference rods 311 provided on the U-shaped body 210 are synchronously approached until they are in contact. After the interference rods 311 are in contact with each other, the interference force pushes the two positioning bodies 36 to move closer on the slide rail 31 through the interference rods 311. The centering movement of the two positioning bodies 36 is synchronously pushed to the center by the existence of the adapter spring 39. Since cables are stored between the arc plates 310, when the arc plates 310 are close to each other When approaching, the cables stored in the arc plate 310 are constrained, and the cables of the same detector are organized and stored in the same group of arc plates 310; further, when the positioning bodies 36 on the U-shaped body 210 are approaching, the two fixing plates 34 are synchronously pushed to move relative to each other, and the relative movement of the fixing plates 34 pushes the two ends of the linkage bar 33 to deflect respectively, so that the linkage bar 33 rotates on the groove 32, and the torsion springs connecting the two ends of the linkage bar 33 with the fixing plates 34 are twisted, and when the cables are subsequently dismantled and released, under the action of the reset torsion spring 35, the two ends of the linkage bar 33 are pushed to deflect in the opposite direction, and then the fixing plates 34 at the two ends of the linkage bar 33 are pushed to move toward the two ends of the slide rail 31, so as to complete the reset operation;

[0052] By adapting the setting of the regular positioning mechanism 3, when the positioning body 36 moves closer on the slide rail 31, the adapter spring 39 makes the arc plate 310 align and close to the storage cable. This regularization and fixing of the cable helps to maintain the stability of the cable connection, thereby ensuring the accurate transmission of data. The cooperation of the slide rail 31, the positioning body 36, the arc plate 310 and other structures can regularize the cables of the same detector into the same group of arc plates 310 for storage. The regular cable layout effectively avoids the disorderly distribution of cables, thereby preventing signal interference caused by mixing of cables between different detectors, such as poor signal coupling, thereby reducing false alarms or inaccurate alarms, and improving the accuracy and reliability of the alarm system. With the help of the adapter spring 39, the arc plate 310 can be adaptively adjusted according to cables of different thicknesses, so that cables of various specifications can be properly fixed. This function of adapting to cables of different thicknesses can not only meet the fixing requirements of different detector cables, but also makes it easier to locate the fault of separately stored cables. By checking the cables of specific detectors, the scope of troubleshooting can be quickly narrowed, the efficiency of troubleshooting can be improved, and it is more conducive to subsequent maintenance and repair work. The stable cable connection can ensure the accurate transmission of combustible gas detection data and avoid false alarms or data loss due to loose cables or poor contact.
