[0025] 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.
[0026] Please see Figures 1-3 The present invention provides the following technical solution.
[0027] Example 1: This example provides a recoverable self-locking wire break alarm, comprising a bedrock 4, a second connecting ring 5, and a steel wire rope 6. The steel wire rope 6 is symmetrically arranged on the left and right sides of the main body 1 of the wire break alarm, and is used to support and connect the main body 1 of the wire break alarm to the bedrock 4. The second connecting ring 5 is provided on the side of the bedrock 4 and is fixed to the bedrock 4 by fastening bolts. The end of the steel wire rope 6 near the bedrock 4 is connected to the second connecting ring 5, and the end of the steel wire rope 6 away from the bedrock 4 is connected to the first connecting ring 3. Figure 1As shown, when installing the broken wire alarm, first remove the alarm and then use a multimeter to measure the continuity of the two wires. If they are connected, the alarm is normal and can be installed and used normally. During installation, drill holes in the bedrock 4 at both ends of the monitoring section to fix the alarm, and fix the second connecting ring 5 to the bedrock 4 with fixing bolts. Then, use a steel wire rope 6 with a diameter greater than φ6 to pull the second connecting ring 5 on the bedrock 4 and connect the other end to the first connecting ring 3, forming a shape like... Figure 1 As shown in the diagram, the disconnection monitoring system should be kept as perpendicular as possible to the direction of the debris flow and be firmly fixed. The alarm signal line should be protected by a conduit and connected to the switch interface of the remote terminal unit to complete the installation of the disconnection alarm. Ensure that the wiring of the disconnection alarm is correct and the connection is stable. The voltage signal power of the disconnection alarm should not exceed DC12V@50mA. The bedrock 4 fixing both ends of the disconnection alarm should preferably withstand a force greater than twice 20kg to prevent the fixed position from disconnecting before the disconnection alarm when subjected to impact, thus rendering the monitoring method ineffective.
[0028] Example 2: This example uses the following technical solution: a resettable self-locking wire break alarm, which is equipped with a wire break alarm. The wire break alarm is composed of a wire break alarm body 1, a movable buckle 2, a spring, a pin, a switching device, and a signal wire. The spring with a fixed force is connected to the pin, and the pin is pressed by the spring force against the internal switching device, making the two ends of the signal wire conductive. The inside of the wire break alarm body 1 is respectively provided with a spring, a pin, a switching device, and a signal wire. The movable buckle 2 is installed on the left end of the wire break alarm body 1, and the left end of the movable buckle 2 and the right end of the wire break alarm body 1 are both fixedly connected to a first connecting ring 3. Figure 1 , Figure 2 , Figure 3 As shown, during use, the disconnection alarm utilizes the deformation characteristics of a spring. A spring with a fixed force is connected to a pin. In the unopened state, the pin is pressed by the spring's elasticity, causing the signal line to conduct. When the disconnection alarm is pulled open with a force of ≥20kg, the spring is compressed and locked by a self-locking switch. The pin also separates from the internal switching device after the spring retracts, breaking the signal line. At this point, the signal line is no longer conductive. During monitoring, if the signal line is connected, it indicates the disconnection alarm is in monitoring mode; otherwise, it indicates the disconnection alarm has been disconnected. If a mudslide or other erosion event occurs in the monitored area, the disconnection alarm may be broken. Combined with a remote terminal unit (RTU), automated monitoring and alarm functions are used to detect and alert on line disconnections. The RTU is a mature and readily available technology and will not be elaborated upon further.
[0029] Furthermore, during use, the status of the disconnection alarm is generally detected using a digital input signal. One end of the alarm wire is connected to 12V, and the other end is connected to the digital input port. In the monitoring state, the digital detection level is high, and when the disconnection alarm is off, a low level is detected. Conversely, the digital input port itself is pulled up to 12V, one end of the alarm wire is connected to ground, and the other end is connected to the digital input port. In the monitoring state, the digital detection level is low, and when the disconnection alarm is off, a high level is detected.
[0030] In addition, combined Figure 3 As shown, when the disconnected alarm is off, it can be manually reset. Apply a pushing force to push the movable buckle 2 on the left side of the disconnected alarm downwards. The pushing force should be around 10kg. After resetting, use a multimeter to measure the continuity of the two wires of the alarm. If they are connected, the alarm is normal. Otherwise, it needs to be repaired or replaced.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
