Description

Technical Field

[0001] This utility model relates to the field of safety equipment for high-altitude operations, and specifically to an intelligent safety belt. Background Technology

[0002] Working at heights is a common practice in industries such as construction, power, and telecommunications. It is inherently dangerous, and falls often have severe consequences. Safety belts, as crucial protective equipment for workers at heights, directly impact their safety. Traditional safety belts consist of a waist belt, safety rope, and connectors, using webbing to support the weight of the worker and provide traction, cushioning, and protection during falls. However, in actual use, the webbing of safety belts faces several potential risks, seriously threatening the safety of workers.

[0003] The work environment contains numerous sharp objects, such as broken rebar and burrs on metal. These objects can instantly sever the unprotected webbing of safety belts during operations. In rough environments like concrete surfaces, the safety belt webbing repeatedly rubs against the surface, causing surface fibers to gradually detach, the internal structure to loosen, and ultimately reducing the webbing's load-bearing capacity. Furthermore, this damage often occurs inside the webbing or in hard-to-see locations, making it difficult for workers to detect visually. The accumulation of this hidden damage can cause the safety belt to lose its protective function at critical moments, leading to serious safety accidents.

[0004] Currently, most safety belts on the market still employ traditional passive protection methods, lacking real-time monitoring of the webbing's condition. Workers can only rely on periodic inspections and experience to assess the safety of the safety belt, a method that is significantly lagging and subjective. With the technological advancements in small and medium-sized electronic devices and structures within the Internet of Things (IoT), applying simple and reliable circuits to the safety belt field promises to enable real-time monitoring and early warning of webbing technology, which is of great significance for improving the safety of high-altitude operations. Utility Model Content

[0005] The purpose of this invention is to address the limitation of traditional safety belts lacking real-time monitoring of webbing condition, and therefore proposes an intelligent safety belt. This intelligent safety belt has a breakage detection component installed within the fixing strap, which can detect the structural integrity of the fixing strap and issue an alarm for initial damage. This invention effectively avoids the problem of workers not being able to promptly detect whether the safety belt is broken or worn, thereby significantly improving the protection of workers' lives and greatly reducing the actual risk of accidents at an economical cost.

[0006] The present invention employs the following technical solution to achieve its objective:

[0007] A smart safety belt comprises multiple interconnected fixed straps positioned in a preset space, forming shoulder straps, waist belts, and tightening straps respectively; characterized in that: each fixed strap is equipped with a breakage detection component, which has a buzzer circuit forming a trigger loop through wires, the wires being evenly distributed and filled inside the corresponding fixed strap; when the fixed strap breaks due to initial structural damage, the corresponding breakage detection component will issue an alarm through the buzzer circuit.

[0008] Furthermore, the breakage detection component is a warning box mounted on a fixed belt; the warning box is equipped with a battery compartment and a buzzer, and the battery compartment contains a removable battery; the buzzer circuit of the breakage detection component has a trigger circuit including a wire and a magnetic component, one end of the wire is connected to the battery, and the other end is connected to the magnetic component; when the wire breaks, the magnetic component flips its state, causing the buzzer to activate and issue an external alarm.

[0009] Furthermore, the magnetic attraction assembly includes an electromagnet, an iron plate, and a spring. The electromagnet is slidably installed inside the warning box, and the iron plate is fixedly installed inside the warning box corresponding to the position of the electromagnet. One end of the spring is fixedly installed inside the warning box, on the same side as the iron plate and the electromagnet, and the other end is connected to the electromagnet. The trigger circuit also includes a first wire, which is composed of a battery, a wire, an electromagnet, and the first wire. When the wire is intact, the trigger circuit is connected, the electromagnet is magnetically attracted to the iron plate, and the spring is compressed. When the wire breaks, the electromagnet loses its magnetic force and moves away from the iron plate under the elastic force of the spring, triggering the buzzer.

[0010] Furthermore, the magnetic attraction assembly also includes a first copper plate and a second copper plate. The first copper plate is fixedly installed inside the warning box, and the second copper plate is fixedly installed on the electromagnet corresponding to the position of the first copper plate. The first copper plate is connected in series with the buzzer and to the battery through a second wire, and the second copper plate is connected to the battery through a third wire. The battery, the third wire, the second copper plate, the first copper plate, the buzzer, and the second wire together constitute the operating circuit of the buzzer circuit. When the wire breaks, the electromagnet moves away from the iron plate, causing the second copper plate to contact the first copper plate and conduct the operating circuit.

[0011] Preferably, indicator lights are connected in parallel to both ends of the battery, and the indicator lights are fixedly installed on the surface of the warning box.

[0012] Preferably, each fixing band includes a first connecting band and a second connecting band, the first connecting band having a cavity inside, and the second connecting band being located inside the cavity; the wires are evenly distributed and filled on the surface of the second connecting band inside the cavity.

[0013] Preferably, the height of the second connecting strip matches the cavity height of the first connecting strip, the length of the second connecting strip is greater than the length of the first connecting strip, and it is accommodated in the cavity of the first connecting strip in a serpentine bend; the wires are evenly distributed and filled on the surface of the second connecting strip, and the filling height is the same as the height of the second connecting strip.

[0014] Specifically, there are two shoulder straps, with a tightening strap connecting the two shoulder straps, and the bottom of both shoulder straps is connected to a circular waistband.

[0015] Specifically, the belt has a first buckle and the tightening belt has a second buckle; the belt is tightened or loosened by the first buckle and the tightening belt is tightened or loosened by the second buckle.

[0016] Specifically, a connector is formed at the connection point between the two shoulder straps, a connecting buckle is fixedly installed on the connector, a first hook is detachably installed on the connecting buckle, a traction rope is fixedly installed on the first hook, and a second hook is fixedly installed on the other end of the traction rope; the second hook is used to connect to the anchor point.

[0017] In summary, due to the adoption of this technical solution, the beneficial effects of this utility model are as follows:

[0018] This invention, by incorporating a breakage detection component, enables an immediate alarm to be issued to workers when initial breakage or damage occurs at any point on the safety belt's fixing strap.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, an intelligent safety belt consists of multiple interconnected fixing straps 1 positioned in a preset space, forming shoulder straps 2, waist belts 3, and tightening straps 4 respectively. Figure 4 As shown, each fixed strip 1 is equipped with a breakage detection component. The breakage detection component has a buzzer circuit that forms a trigger circuit through wires 104. The wires 104 are evenly distributed and filled inside the corresponding fixed strip 1. When the wires of the fixed strip 1 break due to initial structural damage, the corresponding breakage detection component will issue an alarm through the buzzer circuit.

[0031] In this embodiment, any gap or perforation on the fixing strap 1 will reduce the overall structure of the fixing strap 1, greatly weakening its load-bearing capacity. The breakage detection component then promptly alerts the worker wearing the safety belt to prevent accidents. Thanks to the uniform distribution of the conductor 104, any initial structural damage to the fixing strap 1 will trigger the breakage of the conductor 104, thus activating the alarm.

[0032] Example 2

[0033] Based on Example 1, this example provides a detailed structural description of the fracture detection component.

[0034] Combination Figures 3 to 5 The diagram illustrates that the breakage detection component is a warning box 102 mounted on the fixing belt 1. Figure 1 and Figure 2 The warning box 102 is not shown, but its specific location can be adjusted according to the basic structural design of different types of seat belts, or it can be directly installed as shown in the image. Figure 3 As shown, it is positioned at the end of the fixing strap 1; the position of the warning box 102 does not interfere with the interconnection between the multiple fixing straps 1.

[0035] like Figure 3 As shown, the warning box 102 is equipped with a battery compartment 105 and a buzzer 106, and a battery 108 is removably installed inside the battery compartment 105. Figure 5 As shown, the buzzer circuit of the fracture detection component has a trigger circuit including a wire 104 and a magnetic component. One end of the wire 104 is connected to the positive terminal of the battery 108, and the other end is connected to the magnetic component. When the wire 104 breaks, the state of the magnetic component flips, causing the buzzer 106 to activate and issue an external alarm.

[0036] like Figure 5 As shown, the magnetic attraction assembly includes an electromagnet 109, an iron plate 110, and a spring 111. The electromagnet 109 is slidably mounted inside the warning box 102, and the iron plate 110 is fixedly mounted inside the warning box 102 corresponding to the position of the electromagnet 109. One end of the spring 111 is fixedly mounted inside the warning box 102, on the same side as the iron plate 110 with the electromagnet 109, and the other end is connected to the electromagnet 109. The trigger circuit also includes a first wire 113, which is formed by the battery 108, the wire 104, the electromagnet 109, and the first wire 113. When the wire 104 is intact, the trigger circuit is connected, and the electromagnet 109 is magnetically attracted to the iron plate 110, compressing the spring 111. When the wire 104 breaks, a closed circuit cannot be formed between the electromagnet 109 and the battery 108, the electromagnet 109 loses its magnetic force, and moves away from the iron plate 110 under the elastic force of the spring 111, triggering the buzzer 106 to operate.

[0037] like Figure 5 As shown, the magnetic attraction assembly also includes a first copper sheet 112 and a second copper sheet 114. The first copper sheet 112 is fixedly installed inside the warning box 102, and the second copper sheet 114 is fixedly installed on the electromagnet 109 corresponding to the position of the first copper sheet 112. The first copper sheet 112 is connected in series with the buzzer 106 and connected to the battery 108 through the second wire 116, and the second copper sheet 114 is connected to the battery 108 through the third wire 115. The battery 108, the third wire 115, the second copper sheet 114, the first copper sheet 112, the buzzer 106, and the second wire 116 together constitute the operating loop of the buzzer circuit.

[0038] In this embodiment, when the wire 104 is not broken, the trigger circuit is connected while the action circuit is disconnected, and the second copper piece 114 and the first copper piece 112 are not in contact. When the wire 104 is broken, the trigger circuit is disconnected, and the electromagnet 109 moves away from the iron piece 110 under the action of the spring 111, thereby driving the second copper piece 114 to move and make the second copper piece 114 contact the first copper piece 112, thus connecting the action circuit. At this time, the battery 108 supplies power to the buzzer 106, and the buzzer 106 issues an alarm prompt. The worker wearing the safety belt needs to replace the safety belt in time, thereby effectively protecting the worker's life safety.

[0039] As a preferred embodiment, such as Figure 3 , Figure 5 As shown, indicator lights 107 are connected in parallel to both ends of the battery 108, and the indicator lights 107 are fixedly installed on the surface of the warning box 102. By observing whether the indicator lights 107 are lit and their brightness, the battery level of the battery 108 can be determined, and thus, whether the battery 108 needs to be replaced can be determined.

[0040] Example 3

[0041] Based on any of the above embodiments, this embodiment provides a preferred description of the hierarchical structure of the fixing band 1. For example... Figure 4 As shown, each fixing band 1 includes a first connecting band 101 and a second connecting band 103. The interior of the first connecting band 101 forms a cavity, and the second connecting band 103 is located in the cavity. The wires 104 are evenly distributed and filled on the surface of the second connecting band 103 in the cavity.

[0042] In this embodiment, the first connecting belt 101 protects the second connecting belt 103 from external wear. The height of the second connecting belt 103 matches the cavity height of the first connecting belt 101, and the length of the second connecting belt 103 is greater than the length of the first connecting belt 101, and it is accommodated within the cavity of the first connecting belt 101 in a serpentine manner. Typically, both the first connecting belt 101 and the second connecting belt 103 are elastic. When the first connecting belt 101 initially protects the worker, the second connecting belt 103 can continue to maintain protection even after the first connecting belt 101 wears out. Furthermore, when the second connecting belt 103 releases under its elasticity after the first connecting belt 101 wears out, it provides a mechanical reminder to the worker, prompting them to replace the first connecting belt 101 in advance.

[0043] In this embodiment, as Figure 4 As shown, the conductors 104 are evenly distributed and filled on the surface of the second connecting strip 103, with the filling height being the same as the height of the second connecting strip 103. This design ensures that if the second connecting strip 103 is damaged or about to be damaged at any location, it will cause the conductor at the corresponding location to break, thereby triggering subsequent alarm functions.

[0044] Example 4

[0045] Based on any of the above embodiments, this embodiment provides a more detailed description of the structure of the smart seat belt. For example... Figure 1 and Figure 2 As shown, there are two shoulder straps 2, and a tightening strap 4 connects the two shoulder straps 2. The bottom of both shoulder straps 2 is connected to the ring-shaped waist belt 3.

[0046] Furthermore, a first buckle 301 is installed on the waist belt 3, and a second buckle 401 is installed on the tightening belt 4; the waist belt 3 is tightened or loosened by the first buckle 301, and the tightening belt 4 is tightened or loosened by the second buckle 401.

[0047] like Figure 2 As shown, a connector 5 is formed at the connection position between the two shoulder straps 2. A connecting buckle 501 is fixedly installed on the connector 5. A first hook 502 is detachably installed on the connecting buckle 501. A traction rope 503 is fixedly installed on the first hook 502. A second hook 504 is fixedly installed on the other end of the traction rope 503. The second hook 504 is used to connect the anchor point.

[0048] The above basic structural design is an exemplary design for the fixed belt 1 part of the intelligent safety belt that needs to have monitoring function in this embodiment. In actual application, it can also be adaptively added or subtracted according to the other wearing structures of the existing safety belt to ensure the stability and tightness of the worker after wearing the intelligent safety belt, while giving full play to the wear or damage monitoring effect of the corresponding webbing of the safety belt.
