Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an intelligent safety protection device for operations in enclosed spaces during building construction. Background Technology

[0002] Intelligent safety protection devices are devices that combine sensing technology, automatic control, artificial intelligence and other technologies to ensure the safety of personnel, equipment or environment. In the construction process, the working environment in confined spaces (such as underground pipelines, tunnels, storage tanks, basements, etc.) has high-risk factors such as poor air circulation, accumulation of toxic and harmful gases, lack of oxygen, fire, explosion and so on, which can easily lead to safety accidents for construction workers. In order to effectively improve the safety of confined space operations and reduce casualties and property losses, it is necessary to use intelligent safety protection devices for confined space operations in construction.

[0003] Intelligent safety protection devices for enclosed space operations in building construction can be divided into several types, including intelligent environmental monitoring protection devices, intelligent ventilation and exhaust protection devices, and personal protective intelligent equipment. Among them, ventilation and exhaust protection devices improve air circulation, reduce the concentration of harmful gases, and prevent accidents caused by oxygen deficiency or poisoning by automatically adjusting ventilation equipment.

[0004] However, the application of existing technologies in confined space operations still has certain limitations. One prominent issue is that ventilation and lighting equipment require separate supports, occupying significant space. Since confined spaces are typically narrow and have limited working areas, separate supports for ventilation and lighting lead to complex equipment layouts and can even restrict the movement of construction workers. Furthermore, in construction scenarios requiring frequent movement, the separate support structure makes equipment installation and disassembly cumbersome, reducing construction efficiency. Therefore, optimizing the structural design of the equipment to integrate ventilation and lighting fixtures into a single support with automatic sensing and control functions, thereby improving the safety and convenience of confined space construction, has become a pressing technological challenge. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an intelligent safety protection device for construction work in enclosed spaces, which aims to improve the problem that ventilation and lighting equipment need to be set up separately and occupy a large area when working in enclosed spaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent safety protection device for construction work in enclosed spaces, comprising a support frame one and a support frame two, wherein a connecting component is provided between the support frame one and the support frame two, and a protective component is provided inside the support frame one;

[0007] The protective assembly includes a housing, the outer wall of which is fixedly connected to the top of a bracket, a fan fixedly connected inside the housing, a flexible air duct fixedly connected to one end of the housing, an explosion-proof light installed on the outer wall of the bracket, and a human body sensor fixedly connected to the outer wall of the bracket.

[0008] As a further description of the above technical solution:

[0009] The connecting assembly includes a bolt, one end of which is fixedly connected to one end of a bracket, and the bolt passes through the inside of a bracket. A wing nut is threaded onto the outer wall of the bolt.

[0010] As a further description of the above technical solution:

[0011] A fixing column is fixedly connected to the outer wall of the bracket, and a limit groove is formed inside the fixing column.

[0012] As a further description of the above technical solution:

[0013] The fixed column is internally connected to a limiting plate, and a pressing column is fixedly connected to one side of the limiting plate. A positioning block is fixedly connected to the outer wall of the pressing column, and a second limiting groove is formed inside the limiting plate.

[0014] As a further description of the above technical solution:

[0015] A sleeve is fitted on the outer wall of the pressing column, and a limit ring is fixedly connected to the outer wall of the sleeve. The limit ring is rotatably connected inside the limit groove, and the outer wall of the sleeve is fixedly connected to one side of the explosion-proof lamp.

[0016] As a further description of the above technical solution:

[0017] The sleeve has a positioning groove inside, which fits into the positioning block.

[0018] As a further description of the above technical solution:

[0019] A limiting block is fixedly connected inside the fixed column, and the limiting block is slidably connected inside the limiting groove.

[0020] As a further description of the above technical solution:

[0021] A spring is installed inside the fixed column. One end of the spring is fixedly connected inside the fixed column, and the other end of the spring is fixedly connected to the other side of the limiting plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the second bracket is first inserted into the outer wall of the bolt, and the wing nut is screwed into the bolt to tighten and fix it. When someone is working inside, the explosion-proof light and fan can be automatically started by the detection of the human body sensor to improve safety. It achieves the effect of automatically starting the equipment, integrating ventilation and lighting, and is easy to assemble. It solves the problem that ventilation and lighting equipment need to be set up separately and occupy a large area when working in a confined space, and improves the practicality of the safety protection device.

[0024] 2. In this utility model, the positioning block on the outer wall of the pressing column is separated from the positioning groove. Then, the angle of the explosion-proof lamp is adjusted. The explosion-proof lamp rotates inside the fixed column through the sleeve. After it is in place, the pressing column is released. The pressing column is driven to reset by the tension of the spring. This makes it easy to adjust the angle of the explosion-proof lamp, solves the problem that the angle of the construction lighting fixtures in different positions cannot be adjusted, which makes the construction more complicated, and improves the convenience of the safety protection device.

[0030] 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.

[0031] Reference Figure 1 and Figure 2The present invention provides an embodiment of an intelligent safety protection device for construction work in enclosed spaces, comprising a support 1 and a support 2. A connecting component is provided between the support 1 and the support 2. The support 1 is used to provide overall support and fixation, and the support 2 is used to connect other auxiliary equipment and ensure the stability of the device. The support 1 is provided with a protective component to improve the safety of the working environment.

[0032] The protective components include a housing 6, whose outer wall is fixedly connected to the top of the support frame 1, protecting the internal equipment and preventing external dust or moisture from entering and affecting its normal operation. A fan 9 is fixedly connected inside the housing 6, creating airflow within the enclosed space to promptly expel harmful gases and reduce safety hazards in the working environment. A flexible duct 7 is fixedly connected to one end of the housing 6, guiding the airflow from the fan 9 to quickly expel harmful gases from the enclosed space, ensuring workers can operate in a relatively safe air environment. An explosion-proof light 8 is installed on the outer wall of the support frame 1, providing illumination to ensure workers can operate clearly in low-light or no-light conditions, improving work efficiency and safety. A human body sensor 5 is fixedly connected to the outer wall of bracket 1. The human body sensor 5 detects the presence of construction personnel and automatically controls the opening and closing of the explosion-proof lights 8 and fan 9 when personnel enter the work area, achieving intelligent management, reducing manual operation, and improving the equipment's response speed and safety. The connecting components include bolts 3, one end of which is fixedly connected to one end of bracket 1 to ensure connection stability. Bolts 3 pass through the interior of bracket 2, allowing bracket 1 and bracket 2 to fit tightly together, improving the overall rigidity and load-bearing capacity of the device. A wing nut 4 is threaded onto the outer wall of bolt 3, used to lock bolt 3 in place, ensuring a secure connection between bracket 1 and bracket 2, while also facilitating disassembly and adjustment, improving the equipment's installation convenience and adaptability.

[0033] Specifically, during equipment installation, bracket 1 and bracket 2 need to be combined first. The procedure is as follows: bracket 2 is inserted sequentially into the outer wall of bolt 3, allowing them to interlock. Then, the wing nut 4 is rotated to gradually tighten the connection, ensuring a stable connection and effectively improving the overall structural stability. After bracket installation, fan 9 is securely fixed to the top of bracket 2 via housing 6, ensuring it is at a suitable height and angle to maximize ventilation. During operation, fan 9 rapidly and efficiently exhausts accumulated harmful gases from the enclosed space through flexible duct 7, reducing the risk of personnel exposure to hazardous environments while maintaining air circulation and improving work environment safety. Considering the low visibility in enclosed spaces, especially in poor lighting conditions, the device is also equipped with explosion-proof lights 8. These lights provide stable and sufficient illumination in confined spaces, ensuring personnel can clearly observe the work area and preventing misoperation or accidents due to insufficient light. When construction workers enter the enclosed space, the human body sensor 5 inside the device can detect their presence in real time and immediately and automatically activate the explosion-proof light 8 and fan 9, realizing intelligent sensing control without the need for manual activation, which greatly improves the ease of use of the equipment and construction efficiency.

[0034] Reference Figure 3A fixing column 10 is fixedly connected to the outer wall of the bracket 1. The fixing column 10 provides a mounting base for the explosion-proof lamp 8 and ensures stable support when adjusting the angle. A limiting groove 12 is provided inside the fixing column 10 to limit the sliding range of internal components, ensuring the stability and reliability of the structure. A limiting plate 14 is slidably connected inside the fixing column 10. The limiting plate 14 can slide along the limiting groove 12, providing necessary positioning support when adjusting the angle of the explosion-proof lamp 8 and ensuring that the adjusted explosion-proof lamp 8 can be reliably fixed. A pressing column 13 is fixedly connected to one side of the limiting plate 14, providing a manual operation point. By pressing, the limiting plate 14 slides, thereby adjusting the angle of the explosion-proof lamp 8. A positioning block 16 is fixedly connected to the outer wall of the pressing column 13. Under normal circumstances, the positioning block 16 engages with the positioning groove 19, thereby limiting and fixing the angle of the explosion-proof lamp 8 and preventing accidental changes. A second limiting groove 15 is provided inside the limiting plate 14. The second limiting groove 15 is used to limit the sliding range of the limiting block 11, so that the limiting block 11 can move in an orderly manner inside the limiting plate 14, ensuring the smoothness and accuracy of the entire adjustment mechanism during operation. A sleeve 17 is fitted on the outer wall of the pressing column 13. The sleeve 17 is used to provide a rotation fulcrum for the explosion-proof lamp 8, so that it can be adjusted in angle under the constraint of the fixed column 10. A limiting ring 18 is fixedly connected to the outer wall of the sleeve 17. The limiting ring 18 can rotate inside the first limiting groove 12 to provide stable rotational support and prevent the sleeve 17 from axial displacement during adjustment, ensuring that the explosion-proof lamp 8 can be accurately adjusted to the required angle. The outer wall of the sleeve 17 is fixedly connected to one side of the explosion-proof lamp 8, serving to support and transmit torque, allowing the explosion-proof lamp 8 to adjust its angle as the sleeve 17 rotates. A positioning groove 19 is provided inside the sleeve 17, which engages with the positioning block 16, thereby achieving precise angle fixing of the explosion-proof lamp 8 and ensuring that the explosion-proof lamp 8 will not shift due to external forces after adjustment, improving stability in use. A limiting block 11 is fixedly connected inside the fixing column 10, and the limiting block 11 is slidably connected inside the limiting groove 15 to provide limiting guidance, ensuring that the limiting plate 14 will not shift during sliding, maintaining precise operation of the entire mechanism. A spring 20 is provided inside the fixing column 10, providing a restoring force so that the limiting plate 14 can quickly return to its original position after the pressing column 13 is released, allowing the positioning block 16 to re-embed into the positioning groove 19, ensuring the angle fixing effect of the explosion-proof lamp 8. One end of the spring 20 is fixedly connected to the inside of the fixed column 10 to ensure the stability of the spring 20 under force, and the other end of the spring 20 is fixedly connected to the other side of the limiting plate 14 to provide continuous elastic support for the limiting plate 14, ensuring the convenience and reliability of the entire angle adjustment mechanism.

[0035] Specifically, when adjusting the illumination angle of the explosion-proof lamp 8, the pressing column 13 must first be pressed. As the pressing force increases, the positioning block 16 on the outer wall of the pressing column 13 gradually disengages from the positioning groove 19, thereby releasing the angle lock of the explosion-proof lamp 8 and allowing it to rotate freely for adjustment. At this time, the operator can slowly adjust the angle of the explosion-proof lamp 8 according to the actual lighting needs, allowing it to rotate smoothly inside the fixed column 10 through the sleeve 17, ensuring that the light can fully cover the construction area, thereby improving visibility in the confined space and reducing safety hazards caused by insufficient lighting. After adjusting to a suitable illumination angle, the pressing column 13 is released. At this time, the tension of the spring 20 will cause the pressing column 13 to quickly rebound and reset, while simultaneously driving the pressing column 13 to slide along the limiting plate 14 inside the fixed column 10, ensuring that the movement of the pressing column 13 is controlled and does not deviate. Meanwhile, the limiting plate 14, relying on the guiding sliding action of the limiting groove 15 on the outer wall of the limiting block 11, makes the reset process of the pressing column 13 more stable and smooth, thereby further ensuring that the explosion-proof lamp 8 can quickly reset to a stable state after adjustment. Finally, under the action of the rebound force, the positioning block 16 re-embeds into the positioning groove 19, forming a precise fitting and locking, ensuring that the explosion-proof lamp 8 does not loosen or shift after the angle is adjusted, thus firmly fixing it.

[0036] Working principle: When using this intelligent safety protection device for enclosed space operations in building construction, firstly, when combining bracket 1 and bracket 2, simply insert bracket 2 into the outer wall of bolt 3, and then screw the wing nut 4 onto bolt 3 to tighten and fix it. Then, fan 9 is fixed to the top of bracket 2 through housing 6. Fan 9 can timely exhaust harmful gases inside through flexible air duct 7. Then, explosion-proof light 8 can illuminate the confined space. When someone is working inside, the explosion-proof light 8 and fan 9 can be automatically activated by human body sensor 5 to improve safety. It achieves the effect of automatic equipment opening, ventilation and lighting integration, and easy assembly.

[0037] When it is necessary to adjust the illumination angle of the explosion-proof lamp 8, simply press the pressing post 13 to separate the positioning block 16 on the outer wall of the pressing post 13 from the positioning groove 19. Then adjust the angle of the explosion-proof lamp 8. The explosion-proof lamp 8 rotates in the fixed post 10 through the sleeve 17. After it is in place, release the pressing post 13. The pressing post 13 is driven to reset by the tension of the spring 20. The pressing post 13 slides in the fixed post 10 through the limiting plate 14. The limiting plate 14 slides on the outer wall of the limiting block 11 through the limiting groove 15 for further limiting. Then the positioning block 16 is re-embedded in the positioning groove 19, thereby fixing the explosion-proof lamp 8 and making it easy to adjust the angle of the explosion-proof lamp 8.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
