Description

Technical Field

[0001] This utility model relates to the field of high-altitude work equipment technology, and more specifically, to a triangular ring switch for intelligent safety belts designed to prevent falls during high-altitude work. Background Technology

[0002] In the field of working at heights, safety is always of paramount importance. The high incidence and mortality rate of falls from heights cause significant losses to the lives and property of companies and their employees. According to UK workplace fatality statistics, falls account for 15% of industrial fatalities; in my country, from January to June 2017, falls from heights accounted for 41.08% of all types of accidents resulting in death in construction production. One of the main direct causes of these accidents is the failure of workers at heights to use safety belts or their incorrect use.

[0003] With the development of technology, intelligent electronic devices and systems are gradually being introduced into high-altitude operations to improve safety. For example, patents 202311424661.2 disclose a "high-altitude worker fall prevention buckle interlocking device," 202311511138.3 discloses an "intelligent safety belt monitoring and early warning platform," and 202420885665.4 discloses a "high-altitude operation specification monitoring device integrating height sensing function" (not disclosed). These devices, by setting intelligent buckles, pressure sensors, and other equipment on safety ropes, utilize interlocking functions and monitoring systems to regulate the use of safety ropes, thereby reducing the risk of accidents to a certain extent.

[0004] However, existing intelligent safety harness systems for high-altitude operations still have some problems. When using the intelligent buckle, workers need to pull on the rope to confirm safety, especially when it's fastened to a support (such as around a support and fastened to a ring), requiring pulling to ensure stability. Currently, these systems mainly use pressure sensors inside the intelligent buckle hooks to detect the worker's pulling action. If the worker lowers down after securing the main rope, finds a suitable support, attaches the secondary safety rope, and tightens it, the pressure sensors on the ring and hook are activated, sending a signal to the backend to confirm the worker's operation. However, in actual operation, as the worker swings in the air and pulls on the rope, it may slip on the support and get stuck in a position where the pressure sensor cannot withstand the force, leading to a failure to confirm the operation signal and triggering a false alarm. Furthermore, when the rope slips to a position inconvenient for the worker to operate in, the worker needs to readjust the main rope, which is extremely inconvenient while swinging in the air. Utility Model Content

[0005] The purpose of this invention is to provide a triangular ring switch for intelligent safety belts designed for fall protection in high-altitude operations, in order to solve the problem mentioned in the background art where, when workers are swinging and pulling on the rope in the air, the rope may slip on the support and get stuck at a position where the pressure sensor cannot bear the force, resulting in the inability to confirm the operation signal and thus triggering a false alarm.

[0006] To achieve the above objectives, this utility model provides a triangular ring switch for intelligent safety belts designed for fall protection in high-altitude operations. The triangular ring includes a triangular ring with a Bluetooth switch installed on it. The triangular ring has at least three connection ports, two of which are used for the secondary safety rope of the safety belt to pass through, and the remaining connection port is used to fasten with a safety buckle. The Bluetooth switch is communicatively connected to the safety buckle's main unit. When the secondary safety rope is pulled forcefully, the rope triggers the Bluetooth switch, which sends a locking signal to the safety buckle's main unit. The main unit then controls the safety buckle to lock, achieving automatic locking of the safety buckle.

[0007] This feature involves installing a Bluetooth switch on the safety ring, establishing a connection between the ring and the safety buckle and the auxiliary safety rope. The Bluetooth switch communicates with the safety buckle's main unit. When the auxiliary safety rope is pulled forcefully, it triggers the Bluetooth switch, which sends a locking signal to the safety buckle's main unit. The main unit then controls the safety buckle to automatically lock. This process utilizes Bluetooth communication technology to convert the pulling action of the auxiliary safety rope into an electrical signal, achieving automatic locking of the safety buckle through signal transmission and control commands.

[0008] Preferably, the Bluetooth switch is installed at the contact position of the auxiliary safety rope on the triangular ring. The Bluetooth switch includes a main shell, a cover plate installed on the front of the main shell, a back plate installed on the back of the main shell, and a force-bearing block installed on the top of the main shell. One end of the force-bearing block is rotatably connected to the main shell, and a spring is installed between the bottom of the other end and the main shell. A circuit board is installed inside the main shell, and a Bluetooth module and a contact switch are installed on the circuit board. A contact block is installed near the contact switch on the force-bearing block. When the auxiliary safety rope presses down on the force-bearing block of the Bluetooth switch, the force-bearing block overcomes the spring force and makes the contact block contact the contact switch. The signal of the contact switch is sent to the background monitoring system through the Bluetooth module to confirm the operator's operation.

[0009] This Bluetooth switch is installed at the contact point of the auxiliary safety rope on the triangular ring. Its internal structure includes a main shell, cover plate, back plate, force-bearing block, spring, circuit board, Bluetooth module, and contact switch. When the auxiliary safety rope presses down on the force-bearing block, the force-bearing block rotates around its rotational connection point with the main shell, overcoming the spring force and causing the contact block to make contact with the contact switch. The contact switch generates an electrical signal, which is transmitted to the backend monitoring system via the Bluetooth module. This utilizes a mechanical structure to convert the pressure of the auxiliary safety rope into an electrical signal and uses the Bluetooth module to achieve remote signal transmission.

[0010] Preferably, a battery is installed between the main shell and the cover plate.

[0011] This feature involves installing a battery between the main housing and the cover plate to provide power to the electronic components inside the Bluetooth switch, such as the circuit board, Bluetooth module, and contact switch. This ensures that the Bluetooth switch can operate continuously and stably without an external power source, enabling functions such as signal triggering and transmission.

[0012] Preferably, the side of the triangular ring is provided with a slot, and the main shell and the cover plate are equipped with a locking block. The locking block engages with the slot, and the main shell and the cover plate are fixed by bolts.

[0013] This design features a slot on the side of the triangular ring, and locking blocks on the main housing and cover of the Bluetooth switch. The Bluetooth switch is initially positioned on the triangular ring by the engaging action of the locking blocks with the slots. Bolts are then used to connect and secure the main housing and cover, ensuring a stable installation of the Bluetooth switch on the triangular ring. This installation method combines the convenience of a snap-fit ​​connection with the stability of a bolted connection.

[0014] Preferably, one end of the force-bearing block is provided with a pin hole, and a pin is installed on the top of the main shell, with the pin hole rotatably connected to the pin.

[0015] This design features a pin hole at one end of the force-bearing block, with a pin mounted on the top of the main housing. The pin hole and the pin are rotatably connected, allowing the force-bearing block to rotate around the pin. When the auxiliary safety rope applies pressure to the force-bearing block, the block rotates around the pin, triggering a signal action in conjunction with components such as springs and contact switches.

[0016] Preferably, the back panel has a through hole through which the outside of the Bluetooth module passes.

[0017] This design features a through-hole on the back panel, through which the Bluetooth module passes, allowing for better wireless signal transmission. The through-hole design reduces obstruction to Bluetooth signal transmission, ensuring the strength and stability of the transmitted and received signals, and guaranteeing smooth communication between the Bluetooth switch, the security latch host, and the backend monitoring system.

[0018] Preferably, the force-bearing block has a groove near the upper end of the spring, and the upper end of the spring is inserted into the groove.

[0019] This feature includes a groove at the upper end of the force-bearing block near the spring, into which the upper end of the spring engages. This structural design enhances the connection stability between the spring and the force-bearing block. When the auxiliary safety rope presses down on the force-bearing block, the spring is compressed. The cooperation between the groove and the spring effectively prevents the spring from shifting or slipping during the force application process, ensuring that the spring always provides a stable restoring force to the force-bearing block.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This smart safety harness for fall protection in high-altitude operations features a triangular ring switch. By installing a Bluetooth switch on the triangular ring, it changes the previous method of relying solely on pressure sensors inside the smart buckle hook to detect pulling action. When a worker pulls the auxiliary safety rope forcefully, the auxiliary safety rope reliably triggers the Bluetooth switch. This avoids the problem of the rope slipping and getting stuck on the support, preventing the pressure sensor from registering the operation signal and thus reducing false alarms. It ensures that the backend can accurately receive signals that the worker has performed a safe operation.

[0022] Because the Bluetooth switch is mounted on the ring, workers don't need to worry about the main rope slipping into an inconvenient position and needing to readjust it while pulling the auxiliary safety rope to confirm its stability during high-altitude operations. Simply pulling the auxiliary safety rope triggers the Bluetooth switch, which sends a locking signal to the safety buckle's main unit, automatically locking the safety buckle. This greatly improves the convenience of high-altitude operations and reduces the difficulty of operation for workers while swaying in the air.

[0023] The Bluetooth switch features an ingenious structural design. One end of the force-bearing block is rotatably connected to the main housing, while the other end is connected to the main housing via a spring. When the auxiliary safety rope presses down on the force-bearing block, the block overcomes the spring force, causing the contact block to make contact with the contact switch. This design allows for sensitive sensing of the tension in the auxiliary safety rope. Simultaneously, the main housing and cover plate are engaged by a locking block and a slotted ring, then secured with bolts, ensuring the stability of the Bluetooth switch installation and facilitating disassembly and maintenance. The through-hole design on the back plate facilitates Bluetooth module signal transmission, and the cooperation between the spring and the groove in the force-bearing block enhances structural reliability, ensuring stable operation of the entire device in complex high-altitude environments.

[0024] Through communication between the Bluetooth switch and the safety buckle host, the safety buckle automatically locks, further enhancing the safety performance of the safety belt for high-altitude operations in conjunction with the existing interlocking logic. The backend system can promptly and accurately confirm worker operations, effectively monitoring high-altitude work safety, reducing the probability of falls from heights, and providing more reliable protection for the lives of high-altitude workers.

[0031] 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.

[0032] This utility model provides a triangular ring switch for intelligent safety belts designed for fall protection in high-altitude operations, such as... Figure 1 As shown, the device includes a three-pronged ring 1, on which a Bluetooth switch 2 is installed. The three-pronged ring 1 has at least three connection ports, two of which are used for the secondary safety rope of the seat belt to pass through, and the remaining connection port is used to fasten with the safety buckle. The Bluetooth switch 2 is communicatively connected to the safety buckle host. When the secondary safety rope is pulled forcefully, the secondary safety rope triggers the Bluetooth switch 2, and the Bluetooth switch 2 sends a locking signal to the safety buckle host. The safety buckle host controls the safety buckle to lock, thereby realizing the automatic locking of the safety buckle.

[0033] A Bluetooth switch 2 is installed on the triangular ring 1, establishing a connection between the triangular ring 1 and the safety buckle and the auxiliary safety rope of the safety belt. The Bluetooth switch 2 communicates with the safety buckle's main unit. The triangular ring 1 has at least three connection ports, two of which are used for the auxiliary safety rope to pass through the safety belt, and the remaining connection port is used to fasten with the safety buckle. When the auxiliary safety rope is pulled forcefully, it triggers the Bluetooth switch 2, which sends a locking signal to the safety buckle's main unit. The main unit then controls the safety buckle to automatically lock. This process utilizes Bluetooth communication technology to convert the pulling action of the auxiliary safety rope into an electrical signal. Through signal transmission and control commands, the safety buckle automatically locks. This solves the problem of false alarms caused by traditional smart buckles relying on pressure sensors. Even if the rope slides on the support to a position where the pressure sensor cannot exert force, pulling the auxiliary safety rope will trigger the Bluetooth switch 2, ensuring reliable locking of the safety buckle. Simultaneously, automatic locking reduces manual operation steps for workers, improving the convenience and safety of high-altitude operations and reducing safety risks caused by operational errors or failure to lock in time.

[0034] In this embodiment, as Figure 1 , Figure 2 As shown, the Bluetooth switch 2 is installed at the contact position of the auxiliary safety rope on the triangular ring 1. The Bluetooth switch 2 includes a main shell 21, a cover plate 22 installed on the front of the main shell 21, a back plate 211 installed on the back of the main shell 21, a force-bearing block 213 installed on the top of the main shell 21, one end of the force-bearing block 213 is rotatably connected to the main shell 21, and a spring 215 is installed between the bottom of the other end and the main shell 21. A circuit board 214 is installed inside the main shell 21, and a Bluetooth module 216 and a contact switch 2141 are installed on the circuit board 214. A contact block 2132 is installed near the contact switch 2141 on the force-bearing block 213. When the auxiliary safety rope presses down on the force-bearing block 213 of the Bluetooth switch 2, the force-bearing block 213 overcomes the force of the spring 215 and makes the contact block 2132 contact the contact switch 2141. The signal of the contact switch 2141 is sent to the background monitoring system through the Bluetooth module 216 to confirm the operation of the operator.

[0035] Bluetooth switch 2 is installed at the contact position of the auxiliary safety cord on the triangular ring 1. Bluetooth switch 2 includes a main shell 21, a cover plate 22 installed on the front of the main shell 21, a back plate 211 installed on the back of the main shell 21, and a force-bearing block 213 installed on the top of the main shell 21. One end of the force-bearing block 213 is rotatably connected to the main shell 21, and a spring 215 is installed between the bottom of the other end and the main shell 21. A circuit board 214 is installed inside the main shell 21, and a Bluetooth module 216 and a contact switch 2141 are installed on the circuit board 214. A contact block 2132 is installed near the contact switch 2141 on the force-bearing block 213. When the auxiliary safety cord presses down on the force-bearing block 213 of Bluetooth switch 2, the force-bearing block 213 overcomes the force of the spring 215, causing the contact block 2132 to contact the contact switch 2141. The contact switch 2141 generates an electrical signal, which is sent to the background monitoring system through the Bluetooth module 216. This system utilizes a mechanical structure to convert the pressure of the auxiliary safety rope into an electrical signal, which is then transmitted remotely via Bluetooth module 216. The specific structure and working principle of Bluetooth switch 2 are clearly defined, making its sensing of the auxiliary safety rope's tension more sensitive and reliable. Through the cooperation of the mechanical structure and electronic components, the pulling action of the auxiliary safety rope can be accurately captured, avoiding signal loss due to insensitive sensing. This ensures that the back-end monitoring system accurately obtains the operator's operational information, providing strong support for the safety supervision of high-altitude operations.

[0036] Specifically, such as Figure 2 As shown, a battery 23 is installed between the main casing 21 and the cover plate 22.

[0037] A battery 23 is installed between the main housing 21 and the cover plate 22 to provide power to the electronic components inside the Bluetooth switch 2, such as the circuit board 214, Bluetooth module 216, and contact switch 2141. This ensures that the Bluetooth switch 2 can operate continuously and stably without an external power source, enabling it to perform functions such as signal triggering and transmission. This gives the Bluetooth switch 2 independent operating capability, adapting to situations where there is no external power source in high-altitude work environments, thus improving the applicability and stability of the device. Workers do not need to worry about the Bluetooth switch 2 failing due to power problems during high-altitude operations, ensuring the normal operation of the automatic locking function of the safety latch and the background monitoring signal transmission function, further guaranteeing safety during high-altitude operations.

[0038] Furthermore, such as Figure 1 , Figure 2 As shown, the side of the triangular ring 1 has a slot 11, and the main shell 21 and the cover plate 22 are equipped with a locking block 24. The locking block 24 engages with the slot 11, and the main shell 21 and the cover plate 22 are fixed by bolts.

[0039] The side of the triangular ring 1 has a slot 11. The main shell 21 and cover plate 22 of the Bluetooth switch 2 are fitted with locking blocks 24. The locking blocks 24 engage with the slot 11 to initially position the Bluetooth switch 2 on the triangular ring 1. Bolts are then used to connect and fix the main shell 21 and cover plate 22, ensuring the Bluetooth switch 2 is securely mounted on the triangular ring 1. This installation method combines the convenience of locking with the stability of bolted connections. It facilitates the installation and removal of the Bluetooth switch 2, allowing for quick positioning on the triangular ring 1 during installation, reducing installation time and difficulty. It also allows for easy disassembly when maintenance, battery replacement 23, or internal component inspection is required. Simultaneously, the bolted connection ensures that the Bluetooth switch 2 will not loosen or fall off due to shaking, pulling, or other external forces during high-altitude operations, ensuring the Bluetooth switch 2 remains in normal working condition and guaranteeing safety during high-altitude work.

[0040] Furthermore, such as Figure 3 Figure 4 As shown, one end of the force-bearing block 213 is provided with a pin hole 2131, and a pin 212 is installed on the top of the main shell 21. The pin hole 2131 and the pin 212 are rotatably connected.

[0041] One end of the force-bearing block 213 is provided with a pin hole 2131, and a pin 212 is installed on the top of the main shell 21. The pin hole 2131 and the pin 212 are rotatably connected, allowing the force-bearing block 213 to rotate around the pin 212 as the axis. When the auxiliary safety rope applies pressure to the force-bearing block 213, the force-bearing block 213 rotates around the pin 212, realizing linkage with components such as the spring 215 and the contact switch 2141 to complete the signal triggering action. This rotatable connection method provides a stable rotation fulcrum for the force-bearing block 213, ensuring that the force-bearing block 213 can rotate smoothly and stably when subjected to the pressure of the auxiliary safety rope, making the action of the force-bearing block 213 more precise, thereby improving the accuracy and reliability of the Bluetooth switch 2 in sensing the tension of the auxiliary safety rope. This avoids signal triggering failure or delay due to the force-bearing block 213's poor rotation, ensuring that the Bluetooth switch 2 transmits the pulling signal of the auxiliary safety rope to the background monitoring system in a timely and accurate manner.

[0042] Furthermore, such as Figure 3 Figure 4 As shown, a through hole is provided on the back panel 211, and the outside of the Bluetooth module 216 passes through the through hole.

[0043] A through-hole is provided on the back panel 211, through which the outer side of the Bluetooth module 216 passes, allowing the Bluetooth module 216 to better transmit wireless signals to the outside world. The through-hole design reduces obstruction to the signal transmission of the Bluetooth module 216, ensuring the strength and stability of the transmitted and received signals, and ensuring smooth communication between the Bluetooth switch 2, the safety latch host, and the background monitoring system. This improves the signal transmission performance of the Bluetooth switch 2, avoiding signal loss and delays caused by poor signal transmission. It enables the safety latch host to receive the locking signal sent by the Bluetooth switch 2 in a timely manner, achieving rapid and automatic locking of the safety latch; it also ensures that the background monitoring system can obtain real-time operation information of the workers, improving the timeliness and effectiveness of high-altitude operation safety monitoring.

[0044] Furthermore, such as Figure 3 Figure 4 As shown, a groove is provided on the upper end of the force-bearing block 213 near the spring 215, and the upper end of the spring 215 is inserted into the groove.

[0045] A groove is provided at the upper end of the force-bearing block 213 near the spring 215, and the upper end of the spring 215 is inserted into the groove. This structural design enhances the connection stability between the spring 215 and the force-bearing block 213. When the auxiliary safety rope presses down on the force-bearing block 213, the spring 215 is compressed. The cooperation between the groove and the spring 215 effectively prevents the spring 215 from shifting or slipping during the force application process, ensuring that the spring 215 always provides a stable restoring force to the force-bearing block 213. This ensures that the mechanical structure of the Bluetooth switch 2 remains stable and reliable during long-term use, allowing the force-bearing block 213 to accurately reset under the action of the spring 215 each time it is pressed down by the auxiliary safety rope. This ensures that the Bluetooth switch 2 can continuously and stably sense and trigger signals from the tension of the auxiliary safety rope. It also reduces Bluetooth switch 2 malfunctions caused by unstable connection between the spring 215 and the force-bearing block 213, extends the service life of the Bluetooth switch 2, and ensures the normal operation of the high-altitude work intelligent safety belt system.

[0046] When using the intelligent safety belt with a triangular ring switch for fall protection in high-altitude operations, the worker first secures the main rope of the safety belt before starting work. Then, finding a suitable support, the worker passes the secondary safety rope through two connectors of the triangular ring 1 and fastens it to the safety buckle through the remaining connector. At this time, the Bluetooth switch 2 installed on the triangular ring 1 is in standby mode. The battery 23 between the main housing 21 and the cover plate 22 continuously powers the electronic components inside the Bluetooth switch 2, such as the circuit board 214, Bluetooth module 216, and contact switch 2141, ensuring it is always operational.

[0047] The worker pulls the auxiliary safety rope to confirm the stability of the support. The auxiliary safety rope contacts and applies pressure to the force-bearing block 213 of the Bluetooth switch 2. Since one end of the force-bearing block 213 is rotatably connected to the pin 212 on the top of the main housing 21 through the pin hole 2131, and a spring 215 is installed between the bottom of the other end and the main housing 21, under the pressure of the auxiliary safety rope, the force-bearing block 213 overcomes the force of the spring 215 and rotates around the pin 212. As the force-bearing block 213 rotates, the contact block 2132 near the contact switch 2141 comes into contact with the contact switch 2141.

[0048] After contact block 2132 makes contact with contact switch 2141, contact switch 2141 is triggered to generate an electrical signal. This electrical signal is transmitted to Bluetooth module 216 on circuit board 214. Bluetooth module 216 converts the electrical signal into a wireless signal and transmits it to the outside world through the through-hole on back panel 211. Since Bluetooth switch 2 is communicatively connected to the safety latch host, the signal sent by Bluetooth module 216 is received by the safety latch host; at the same time, the signal is also transmitted to the background monitoring system.

[0049] After receiving the locking signal from Bluetooth switch 2, the safety buckle main unit controls the safety buckle to lock according to the preset program, achieving automatic locking and ensuring the safety of workers when working at heights. Upon receiving the signal, the background monitoring system confirms that the operator has performed the corresponding operation, thereby effectively supervising the safe operation of high-altitude work and ensuring the safety of the entire work process.

[0050] When the tension of the auxiliary safety rope disappears, under the restoring force of the spring 215, the force block 213 rotates in the opposite direction around the pin 212 to reset, the contact block 2132 separates from the contact switch 2141, and the Bluetooth switch 2 returns to the standby state, waiting to trigger the working process again when the auxiliary safety rope is pulled next time.

[0051] Finally, it should be noted that the electronic components in the circuit board 214 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components are connected by wires.
