Description
Technical Field
[0001] This utility model belongs to the technical field of chemical production safety equipment, specifically a chemical production safety protection device. Background Technology
[0002] Chemical production processes involve various toxic and hazardous media, resulting in complex working environments and high safety risks. Among these, toxic gas leaks are a common safety hazard; if not detected and warned of in a timely manner, they can lead to worker poisoning or even endanger their lives.
[0003] A search revealed a utility model patent with publication number CN218759204U and publication date of 2023-03-28, entitled "A Safety Protection Device for Chemical Production." While this patent addresses the issue of "conveniently connecting the protective rod through the adsorption and cooperation of the first and second magnetic blocks, with the rotating rod able to unfold or retract the protective belt under the action of a torsion spring, and the structural design of the limiting plate and limiting groove, limiting rod and groove ensuring the stability of the protective device in the unfolded state, primarily used to delineate hazardous work areas and achieve physical isolation," a deeper analysis of its technical solution reveals that this device only provides passive protection through mechanical structure for area separation, lacking any active monitoring and early warning for toxic gas leaks. In actual chemical production, when a toxic gas leak occurs, even if personnel are isolated outside the protected area, they may still accidentally enter the hazardous area due to the inability to detect the leak, or fail to evacuate in time while working within the protected area. Its safety protection system has significant functional shortcomings and cannot comprehensively guarantee the safety of personnel in chemical production. Summary of the Invention
[0004] To address the problems existing in the background technology, this utility model provides a safety protection device for chemical production.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chemical production safety protection device, comprising a vehicle body, a fixed column, a gas detection mechanism, a support frame, a photovoltaic panel, a power supply box, a PU spring wire one, a PU spring wire two, and two extension mechanisms; The vehicle body is equipped with omnidirectional wheels at its lower end and is fixedly connected to a fixed column at its upper end. The upper end of the fixed column is fixedly connected to a gas detection mechanism. The upper end of the gas detection mechanism is fixedly connected to a photovoltaic panel via a support frame. The photovoltaic panel is electrically connected to a power box via a PU spring wire. The power box is mounted on the vehicle body and is electrically connected to the gas detection mechanism via a PU spring wire. Extension mechanisms are provided on both sides of the fixed column, and each extension mechanism is electrically connected to the gas detection mechanism. The two extension mechanisms are symmetrically arranged.
[0006] Each of the aforementioned extension mechanisms includes a column, a warning light, a PU spring wire, a threaded rod, a base plate, and two telescopic units; The upper end of the column is fixedly connected to the warning light, which is electrically connected to the gas detection mechanism via a PU spring wire. The side wall of the column is connected to the fixed column via two symmetrically arranged telescopic units. The lower end of the column is provided with a threaded groove, which is threadedly connected to the upper end of the threaded rod. The lower end of the threaded rod is fixedly connected to the base plate.
[0007] Each of the telescopic units includes a barrier belt, a belt reel, and a coil spring; The fixed column has two grooves on both sides. The two ends of the winding rod are fixedly installed in the corresponding grooves. A coil spring is sleeved on the outside of the winding rod. The inner ring of the coil spring is fixedly connected to the winding rod. The outer ring of the coil spring is fixedly connected to one end of the isolation strip. The other end of the isolation strip is fixedly connected to the column.
[0008] Both sides of the upper end of the vehicle body are provided with placement slots that match the base plate, and each base plate is placed in the corresponding placement slot.
[0009] The chemical production safety protection device also includes a display screen, which is connected to the gas detection mechanism via a data cable, electrically connected to the power supply box, and mounted on a fixed column.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. Flexible and mobile, adaptable to multiple monitoring scenarios: This device uses a vehicle with omnidirectional wheels as its carrier, which can be easily pushed to any location in chemical production where gas needs to be monitored (such as around the reactor, raw material storage area, pipeline interface, etc.), allowing for rapid deployment and solving the problems of limited coverage and inconvenient adjustment of traditional fixed monitoring equipment, thereby improving monitoring flexibility.
[0011] 2. Photovoltaic power supply ensures continuous operation: Photovoltaic panels are mounted on a support frame above the gas detection mechanism, converting solar energy into electrical energy and storing it in the power box. This eliminates the need for an external power source, avoiding the potential wiring hazards in chemical areas and providing power to core components such as the detection mechanism and display screen. This ensures stable operation of the device for extended periods and is suitable for outdoor or temporary scenarios.
[0012] 3. Telescopic isolation for efficient delineation of danger zones: Extension mechanisms are installed on both sides of the fixed column. When the column is pulled out, the isolation strip extends simultaneously. Rotating the base plate can drive the threaded rod to move down, allowing the base plate to land and be fixed, preventing the spring from rebounding and keeping the isolation strip stretched, forming a protective barrier to prevent unauthorized personnel from entering and to remind the site of safety.
[0013] 4. Intelligent detection and warning for timely response to potential hazards: Gas detection agencies can accurately detect harmful gases such as hydrogen sulfide and carbon monoxide in real time, and transmit the data to the display screen for personnel to view; when the concentration exceeds the threshold, the warning light will be triggered immediately to realize the linkage between "detection and warning", which can buy time for personnel to respond to emergencies and avoid leakage accidents.
[0014] 5. Automatic storage enhances ease of use: The spring of the telescopic unit can automatically rewind the isolation belt back to the winding rod, and the column can be easily reset; the two sides of the vehicle body are equipped with placement slots, and the base plate can be directly placed in, saving space, making storage efficient, reducing the workload of operators, and facilitating the transportation and storage of the device.
[0015] 6. Stable wiring ensures component coordination: All components are electrically connected by PU spring wires, which are durable and can maintain a stable connection as the components move, avoiding line breakage and failure; the display screen and the testing mechanism transmit data stably through data cables, ensuring that the core components work together and improving the reliability of the device.
[0016] In summary, this utility model addresses the pain points of traditional monitoring equipment through designs such as "flexible mobility + photovoltaic power supply + telescopic protection + intelligent early warning + convenient storage + stable wiring," achieving full-process protection of "monitoring-early warning-protection." It improves the flexibility and safety of chemical production monitoring while reducing operation and maintenance costs, and adapts to diverse safety monitoring needs. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.
[0019] This embodiment describes a safety protection device for chemical production, including a vehicle body 1, a fixed column 2, a gas detection mechanism 3, a support frame 4, a photovoltaic panel 5, a power supply box 6, a PU spring wire 1 7, a PU spring wire 2 8, and two extension mechanisms. The lower end of the vehicle body 1 is equipped with omnidirectional wheels, and the upper end of the vehicle body 1 is fixedly connected to the fixed column 2. The upper end of the fixed column 2 is fixedly connected to the gas detection mechanism 3. The upper end of the gas detection mechanism 3 is fixedly connected to the photovoltaic panel 5 through the support frame 4. The photovoltaic panel 5 is electrically connected to the power box 6 through PU spring wire 7. The power box 6 is installed on the vehicle body 1 and is electrically connected to the gas detection mechanism 3 through PU spring wire 8. Extension mechanisms are provided on both sides of the fixed column 2. Each extension mechanism is electrically connected to the gas detection mechanism 3, and the two extension mechanisms are symmetrically arranged.
[0020] Each of the aforementioned extension mechanisms includes a column 9, a warning light 10, a PU spring wire 11, a threaded rod 14, a base plate 15, and two telescopic units; The upper end of the column 9 is fixedly connected to the warning light 10. The warning light 10 is electrically connected to the gas detection mechanism 3 through the PU spring wire 11. The side wall of the column 9 is connected to the fixed column 2 through two telescopic units arranged symmetrically above and below. The lower end of the column 9 is provided with a threaded groove, which is threadedly connected to the upper end of the threaded rod 14. The lower end of the threaded rod 14 is fixedly connected to the base plate 15.
[0021] Each of the telescopic units includes a barrier belt 12, a belt reel 13, and a coil spring; The fixed column 2 has two grooves on both sides. The two ends of the winding rod 13 are fixedly installed in the corresponding grooves. A coil spring is sleeved on the outside of the winding rod 13. The inner ring of the coil spring is fixedly connected to the winding rod 13. The outer ring of the coil spring is fixedly connected to one end of the isolation strip 12. The other end of the isolation strip 12 is fixedly connected to the column 9.
[0022] Both sides of the upper end of the vehicle body 1 are provided with placement slots that match the base plate 15, and each base plate 15 is placed in the corresponding placement slot.
[0023] The chemical production safety protection device also includes a display screen 16, which is connected to the gas detection mechanism 3 via a data cable, electrically connected to the power supply box 6, and mounted on the fixed column 2.
[0024] This chemical production safety protection device uses a vehicle body 1 as its mobile carrier. The lower end of the vehicle body 1 is equipped with omnidirectional wheels, allowing operators to easily move the device to specific locations in chemical production where gases need to be monitored. A fixed column 2 is securely connected to the upper end of the vehicle body 1 to provide a stable support structure. The upper end of the fixed column 2 connects to the gas detection mechanism 3, which serves as the core monitoring component. A photovoltaic panel 5 is mounted on the upper end of the gas detection mechanism 3 via a support frame 4. The photovoltaic panel 5 acts as an energy collection component; after deployment, it is activated to convert solar energy into electrical energy, which is then transmitted via a PU spring wire 7 to a power box 6 on the vehicle body 1 for storage, providing continuous power support for the device's subsequent stable operation. The source box 6 is electrically connected to the gas detection mechanism 3 via PU spring wire 2 8 to supply power and ensure stable operation. It is also electrically connected to the display screen 16 to provide power. Symmetrical extension mechanisms are arranged on both sides of the fixed column 2. Each extension mechanism includes a column 9. After reaching the designated monitoring position, the operator can pull the column 9 out to both sides. During the pulling process, the isolation strip 12, connected to the side wall of the column 9 via two symmetrical telescopic units, extends synchronously with the movement of the column 9. Each telescopic unit consists of the isolation strip 12, a winding rod 13, and a coil spring. Two grooves are provided on both sides of the fixed column 2. The two ends of the winding rod 13 are fixed in the grooves, and a coil spring is sleeved on the outer side. The inner ring of the coil spring is connected to the coiling rod 13, and the outer ring is connected to one end of the isolation strip 12. The other end of the isolation strip 12 is connected to the column 9. At the same time, the base plate 15, which was originally placed in the matching slots on both sides of the upper end of the vehicle body 1, will also be moved out with the column 9. Then, the operator rotates the base plate 15 at the lower end of the column 9, which drives the threaded rod 14 to move downward along the threaded groove at the lower end of the column 9 until the base plate 15 lands steadily on the ground. The weight of the base plate 15 itself prevents the coil spring of the telescopic unit from rebounding, ensuring that the isolation strip 12 remains stretched, forming a protective barrier around the device. This protective barrier can delineate the dangerous monitoring area, prevent unauthorized personnel from entering, and at the same time remind on-site personnel that the area is under gas monitoring. When moving the column 9, the PU spring wire 11 connected to the warning light 10 installed at its upper end will extend and retract accordingly, always maintaining electrical connection with the gas detection mechanism 3, so as to receive abnormal signal alarms. When the device is retracted, the operator must first rotate the base plate 15 in the opposite direction, driving the threaded rod 14 to retract upward along the threaded groove at the lower end of the column 9 until the threaded rod 14 is fully embedded in the threaded groove. Then, the base plate 15 is placed into the placement slots on both sides of the upper end of the vehicle body 1. Subsequently, the coil spring in the telescopic unit will automatically retract the isolation belt 12 and the winding rod 13 through its own rebound characteristics, while pulling the column 9 back to the direction of the fixed column 2, thus completing the storage of the device.The device is equipped with a display screen 16 mounted on a fixed column 2 for easy observation by operators. It is connected to the gas detection mechanism 3 via a data cable. When the gas detection mechanism 3 is activated (using existing mature technology, referencing the gas detection device in CN221222091U, which accurately detects hazardous chemical gases such as hydrogen sulfide and carbon monoxide and transmits the detection data to the display screen 16 for real-time display), it monitors the gas composition and concentration in the surrounding chemical environment in real time. The detection data is transmitted to the display screen 16 via the data cable, allowing operators to intuitively obtain current gas values and understand the gas status of the chemical production area. If a hazardous gas leak occurs in the chemical production area, and the gas value detected by the gas detection mechanism 3 exceeds a preset safety threshold, it will immediately send a signal to the warning light 10 via two connected PU spring wires 11. Upon receiving the signal, the warning light 10 quickly issues an alarm, attracting the attention of on-site personnel and reminding them to take timely countermeasures to avoid safety accidents caused by hazardous gas leaks.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within this invention.
