Description

Technical Field

[0001] The present invention relates to the field of safety protection for high-altitude construction operations, and particularly to an intelligent safety protection device. Background Art

[0002] During high-altitude operations, high-altitude workers need to wear safety protection devices, and high-altitude work safety belts are common safety protection devices. A high-altitude work safety belt, also known as an all-round safety belt or a five-point safety belt, includes a shoulder strap, a chest strap, a waist strap, and leg straps, and is used in conjunction with a suspension rope to provide all-round protection for high-altitude workers and prevent falling casualties. Buckles are provided on the chest strap, waist strap, and leg straps. Sometimes, high-altitude workers may neglect to fasten the buckles tightly or the buckles may loosen due to other reasons, posing a safety risk. Summary of the Invention

[0003] Aiming at the safety risk of incorrect wearing of buckles during high-altitude operations in the prior art, the present invention provides an intelligent safety protection device, which reduces the safety risk of high-altitude operations by providing a buckle connection device with higher safety performance and detecting whether the buckle connection device is correctly worn.

[0004] To solve the above technical problems, the present invention includes the following technical solutions:

[0005] An intelligent safety protection device is provided with a buckle connection device, a processor, and a voice broadcast device.

[0006] The buckle connection device includes a lock, a buckle, and a locking buckle.

[0007] The lock is provided with a first lock hole and a second lock hole. A lock plate is arranged in the first lock hole, and first pressure sensors are arranged at intervals on the inner side of the lock plate. The second lock hole is perpendicular to and communicates with the first lock hole. A slot and a turning slot are arranged on the lock plate, and the widths of the slot and the turning slot are respectively denoted as L1 and L2.

[0008] The buckle includes a bolt and a hook. The hook is L-shaped, and one end is perpendicularly connected to the end of the bolt. The thicknesses of both ends of the hook are respectively L3 and L4, satisfying L4 < L2 < L3 < L1. The hook can be inserted into the slot and rotated along the turning slot until the third lock hole matches the position of the second lock hole, and the hook presses against the first pressure sensor. A third lock hole is arranged on the bolt, and a second pressure sensor is arranged in the third lock hole.

[0009] The locking buckle includes a handle, a pin shaft, a ring plate and a spring. One end of the pin shaft is connected to the handle. The ring plate is sleeved on the pin shaft. The pin shaft and the ring plate are located in the second locking hole. One end of the spring is connected to the buckle, and the other end is connected to the ring plate. The elastic force of the spring can make one end of the pin shaft insert into the first locking hole. When the hook rotates along the turning groove to a position where the third locking hole matches the second locking hole, the pin shaft inserts into the third locking hole and abuts against the second pressure sensor.

[0010] After the first pressure sensor and the second pressure sensor are pressed, they respectively send a first signal and a second signal to the processor. After receiving the first signal and the second signal, the processor determines that the snap connection device has been correctly snapped. The controller can control the voice broadcast device to broadcast a prompt message indicating whether the snap connection device is correctly snapped.

[0011] Furthermore, the intelligent safety protection device includes a timer. When the processor determines that all snap connection devices have been correctly worn, the timer records T1. When the processor determines that a snap connection device has been opened, the timer records T2. The processor calculates the value of T2 - T1 and uses it as the working duration.

[0012] Furthermore, the processor collects the working duration of the worker on the same day and uses it as the daily working duration △T1 of the worker. The daily attendance duration of the worker is recorded as △T2. A coefficient a is set, and it is required to satisfy △T1 / △T2 ≥ a, where a is a decimal between 0 and 1. If △T1 / △T2 < a, the processor prompts the project management personnel to understand the situation and reminds the relevant workers to do a good job in safety protection.

[0013] Furthermore, the intelligent safety protection device further includes a safety rope. A dynamometer is provided on the safety rope. The dynamometer can measure the acting force F1 on the safety rope, and the dynamometer sends the measurement result to the processor.

[0014] A preset value F0 is set in the processor. When F1 ≥ F0, the processor determines that the tension of the safety rope is abnormal and controls the voice broadcast device to broadcast a prompt message indicating the abnormal tension of the safety rope.

[0015] Furthermore, a shock-absorbing spring is provided on the safety rope. The processor receives the measurement result of the dynamometer and determines whether the shock-absorbing spring vibrates abnormally. When it is determined that the shock-absorbing spring vibrates abnormally, it controls the voice broadcast device to broadcast the information of the abnormal vibration of the shock-absorbing spring and sends this information to the remote server or the management personnel.

[0016] Furthermore, the intelligent safety protection device further includes a safety belt. A safety airbag is provided on the safety belt. When the processor determines that the tension of the safety rope is abnormal or the shock-absorbing spring vibrates abnormally, the controller controls the opening of the safety airbag.

[0017] Due to the above technical solutions, the present invention has the following advantages and positive effects compared to the prior art: The intelligent safety protection device provided by the present invention includes a snap-on connection device with higher safety performance. The hook of the plug buckle is inserted into the slot of the lock plate, rotated, and locked with the lock plate. Then, the spring drives the pin of the locking buckle into the third lock hole to lock the pin, making the snap-on connection device safer and more reliable. The processor determines whether the snap-on connection device is correctly worn based on whether it receives the first signal and the second signal from the first pressure sensor and the second pressure sensor, and issues a voice prompt through the voice broadcast device, effectively reducing the safety risks caused by improper wearing of the snap-on connection device. Furthermore, by providing a timer, whether the snap-on connection device is correctly worn is directly linked to the worker's working hours, which can encourage workers to actively wear the snap-on connection device correctly. In addition, by providing a dynamometer and a shock-absorbing spring on the safety rope and an airbag on the safety belt, the controller determines whether an abnormality occurs and activates the airbag when an abnormality occurs, thereby reducing injuries to workers in safety accidents.

[0030] The intelligent safety protection device provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. In combination with the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non - precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention.

[0031] The intelligent safety protection device provided in this embodiment can be common protection devices such as safety belts and safety suits equipped with snap - connection devices. In this embodiment, a safety belt is taken as an example for introduction. In combination with Figures 1 to 5 as shown, the intelligent safety protection device includes a snap - connection device 15, a processor 6 and a voice broadcast device 7.

[0032] As Figure 1 shown, the safety belt 1 includes a shoulder strap 11, a chest strap 12, a waist strap 13 and a leg strap 14, and a snap - connection device 15 is provided on the chest strap 12, the waist strap 13 and the leg strap 14. In combination with Figure 1 and Figure 2 as shown, the snap - connection device 15 includes a lock 3, a buckle 4 and a locking buckle 5.

[0033] In combination with Figures 2 to 4 as shown, a first lock hole 31 and a second lock hole 34 are provided on the lock 3. The first lock hole 31 is used to cooperate with the buckle 4, and the second lock hole 34 is used to cooperate with the locking buckle 5. A lock plate 32 is provided in the first lock hole 31. The lock plate 32 is a vertically arranged plate, perpendicular to the length direction of the first lock hole 31. A communicating slot 321 and a turning slot 322 are provided on the lock plate 32. The slot 321 is a rectangular slot, and the turning slot is an arc - shaped slot. The widths of the slot 321 and the turning slot 322 are respectively denoted as L1 and L2, and L1 < L2. The widths of the slot and the turning slot are referred to Figure 3 . A first pressure sensor 33 is provided at the end of the first lock hole 31 inside the lock plate 32, and there is a gap between the first pressure sensor 33 and the lock plate 32. The second lock hole 34 is perpendicular and communicated with the first lock hole 31.

[0034] See Figure 2As shown, the snap fastener 4 includes a bolt 41 and a hook 42. The hook 42 is L-shaped, and one end is perpendicularly connected to the end of the bolt 41. The thicknesses of both ends of the hook 42 are L3 and L4 respectively, and L4 < L3. That is, the left end of the hook is L3 and the right side is L4. It also satisfies L4 < L2 < L3 < L1. The hook 42 can be inserted into the slot 321, and the hook 42 can rotate along the turning groove 322. After rotation, the hook 42 deviates from the slot 321. The hook 42 is in the turning groove, and the width of the hook is greater than the width of the turning groove, so the hook cannot be pulled out. A third lock hole 43 is provided on the bolt 41. The bolt 41 rotates together with the hook 42. The bolt 41 can rotate to a position where the third lock hole 43 matches the second lock hole 34. At this time, the hook 42 can press against the first pressure sensor 33. After the first pressure sensor 33 is pressed, it sends a first signal to the processor 6. In addition, a second pressure sensor 44 is provided in the third lock hole 43.

[0035] Combined with Figure 2 and Figure 4 As shown, the locking buckle 5 includes a handle 51, a pin shaft 52, an annular plate 53 and a spring 54. One end of the pin shaft 52 is connected to the handle 51. The annular plate 53 is sleeved on the pin shaft 52. The pin shaft 52 and the annular plate 53 are located in the second lock hole 34. One end of the spring 54 is connected to the buckle 3, and the other end is connected to the annular plate 53. The elastic force of the spring 54 can make one end of the pin shaft 52 insert into the first lock hole 31. When the hook 42 rotates along the turning groove 322 to a position where the third lock hole 43 matches the second lock hole 34, the elastic force of the spring 54 makes the pin shaft 52 insert into the third lock hole 43 and press against the second pressure sensor 44. After the second pressure sensor 44 is pressed, it sends a second signal to the processor 6.

[0036] After the first pressure sensor 33 and the second pressure sensor 44 are pressed, they send a first signal and a second signal to the processor 6 respectively. After receiving the first signal and the second signal, the processor 6 determines that the snap connection device has been correctly snapped; the controller can control the voice broadcast device 7 to broadcast a prompt message indicating whether the snap connection device is correctly snapped.

[0037] The intelligent safety protection device provided in this embodiment can insert the hook 42 of the snap fastener 4 into the slot 321 of the lock plate 32, rotate and snap with the lock plate 32, and then drive the pin shaft 52 of the locking buckle 5 to insert into the third lock hole 43 by the spring 54 to lock the bolt 41, which improves the safety of the snap connection device itself. And it determines whether the snap connection device is correctly worn by whether the processor 6 receives the first signal and the second signal sent by the first pressure sensor 33 and the second pressure sensor 44, and emits a prompt voice through the voice broadcast device 7, which can effectively reduce the safety risk caused by the incorrect wearing of the snap connection device.

[0038] In a specific embodiment, the intelligent safety protection device further includes a timer. When the processor 6 determines that all the buckle connection devices have been correctly worn, it controls the timer to start timing, and the start time is recorded as T1. When the processor 6 determines that a buckle connection device has been opened, the timer stops timing, and the end time is recorded as T2. The processor 6 calculates the value of T2 - T1 as the working duration, and the processor 6 aggregates the daily working durations of the workers on the same day as the daily working duration of the worker, and this daily working duration is the safe working duration △T1. By directly linking whether the buckle connection devices are correctly worn with the statistics of the workers' working durations, this embodiment can prompt the workers to actively and correctly wear the buckle connection devices. Further, the daily attendance durations of each worker will be recorded at the construction site. For example, the commuting times are recorded through fingerprint recognition, face recognition, card swiping recognition, scanning recognition, DingTalk clock-in, etc. when commuting to and from work to calculate the daily attendance duration △T2. A coefficient a is set, and it is required to satisfy △T1 / △T2≥a, where a is a decimal between 0 and 1. For example, a can take values such as 0.6, 0.7, or 0.8. For workers who meet the requirements for a certain period, safety bonuses can be sent to prompt the workers to enhance their safety awareness and do a good job in safety protection. If △T / △T2 < a, it indicates that there may be a safety risk, and it is necessary to prompt the project management personnel to understand the situation and remind the relevant workers to do a good job in safety protection. By taking preventive measures, the probability of safety accidents can be effectively reduced.

[0039] In a specific embodiment, the intelligent safety protection device further includes a safety rope used in conjunction with the safety belt. A force gauge 21 is provided on the safety rope, and the force gauge 21 can measure the acting force F1 on the safety rope 2, and the force gauge sends the measurement result to the processor 6. A preset value F0 is set in the processor 6. When F1≥F0, the processor 6 determines that the tension of the safety rope is abnormal and controls the voice broadcast device 7 to broadcast a prompt message indicating that the tension of the safety rope is abnormal. Generally, the acting force F1 on the safety rope is much smaller than the weight of the worker. When the acting force F1 on the safety rope suddenly increases, attention needs to be paid. A preset value F0 can be set in the processor 6. For example, the preset value can be linked to the weight G of the human body 42. As an example, F0 = 0.4G, 0.5G, 0.75G, 0.8G, etc. In particular, the management personnel should pay sufficient attention to the abnormal acting force on the safety ropes of the workers.

[0040] In one embodiment, the safety harness is equipped with a shock-absorbing spring 22. If a worker falls and becomes suspended in mid-air by the harness, the shock-absorbing spring 22 mitigates the impact of the safety harness's force on the worker, reducing discomfort or injury. Furthermore, when the shock-absorbing spring 22 vibrates significantly, the force measured by the dynamometer will also exhibit regular and significant fluctuations. When the processor 6 receives the dynamometer's measurement results and determines that the shock-absorbing spring 22 is vibrating significantly, it controls the voice notification device 7 to announce the abnormal vibration of the shock-absorbing spring 22 and transmits this information to the remote server 8 or a management personnel.

[0041] In a specific embodiment, the intelligent safety protection device includes a seat belt 1, and airbags 16 are provided in front and behind the shoulder straps of the seat belt 1. When the processor 6 determines that the tension of the safety rope is abnormal or the shock-absorbing spring 22 vibrates greatly, the controller controls the opening of the airbag 16.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely illustrate several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that a person skilled in the art would be able to make numerous modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
