Description

Technical Field

[0001] The present invention relates to the field of electrostatic protection, and particularly to an explosion-proof gate-type personnel electrostatic protection qualification confirmation instrument. Background Art

[0002] According to the national standard GB / T 39587-2020 "General Requirements for Electrostatic Protection Management", electrostatic and electrostatic discharge will have a series of adverse effects on scientific research, production, storage and transportation, use, disposal and other activities in many industries such as electronic products, petrochemical industry, civil explosives and military industry. The effect of electrostatic protection work is directly related to production safety and product quality. If a person carrying static electricity touches a conductive object (for example, a doorknob, a railing, a metal object), a spark will be generated at the contact point. It is unlikely for people to see, hear, or even feel this spark, but the spark generated by the human body can cause the ignition of surrounding gases, vapors, and even some more sensitive dusts. Especially in chemical plants, dangerous goods storage areas, and flammable and explosive dangerous working areas that require interlocking with explosion-proof gates in the wild, it is difficult to ensure the control and monitoring of personnel electrostatic protection measures in chemical production, chemical storage and transportation, outdoor temporary operation areas for refining, oil extraction, gas extraction, and explosion hazardous areas. Therefore, it is necessary to improve it. Summary of the Invention

[0003] Based on this, in view of the problem that it is difficult to ensure the control and monitoring of personnel electrostatic protection measures in chemical production, chemical storage and transportation, and flammable and explosive dangerous working areas that require interlocking with explosion-proof gates in the wild, such as refining, oil extraction, gas extraction, and explosion hazardous areas, it is necessary to provide an explosion-proof gate-type personnel electrostatic protection qualification confirmation instrument.

[0010] Metal foot pedal, electrically connected to the detection interface of the explosion-proof personnel static protection confirmation instrument body, and used for the anti-static shoes worn by personnel to step on.

[0011] In one embodiment, the explosion-proof personnel static protection confirmation instrument body is fixed or mobile.

[0012] In one embodiment, the metal foot pedal is equipotentially connected to the grounding pile of the earth, and the metal foot pedal, grounding pile, human body, and the static protection measures worn by the human body together form a detection circuit on the explosion-proof personnel static protection confirmation instrument body.

[0013] In one embodiment, the explosion-proof personnel static protection confirmation instrument body also has a main control board and a display panel. The main control board has a controller, and the display panel has LED status indicators and a digital tube or a liquid crystal screen. The controller is used to process the static resistance data on the detection circuit and transmit the detection result to the digital tube or the liquid crystal screen.

[0014] In one embodiment, the controller includes a receiving module, a signal driving module, a communication module, and a display module. The receiving module is used to receive the static resistance data of the detection circuit in real time. The signal driving module is used to instruct the explosion-proof voice alarm to alarm. The display module is used to output information on whether the static protection is qualified in response to the static resistance data on the detection circuit within the first threshold range. The communication module is used to transmit the detection result and the alarm information to an external monitoring system and support remote control of the opening and closing of the explosion-proof barrier gate.

[0015] In one embodiment, the communication module is an RS485 or LORA communication module.

[0016] In one embodiment, the signal driving module includes an output unit and an instruction unit. The output unit is used to output an instruction signal in response to the static resistance data on the detection circuit exceeding the set threshold. The instruction unit is used to instruct the explosion-proof voice alarm to alarm and interlock the explosion-proof barrier gate to open and close based on the instruction signal.

[0017] In one embodiment, the controller further includes a data storage module. The data storage module is used to record the resistance value, timestamp, and operator identity information of each detection, and supports data export and analysis.

[0018] In one embodiment, the explosion-proof human static eliminator includes a touch button and a static release ball. The touch button is built with a contact sensor and is used to detect the contact of a human hand and activate the static release ball to work.

[0019] In one embodiment, the explosion-proof personnel static protection confirmation instrument is built with an explosion-proof battery and a power management module. The power management module supports solar charging and conventional industrial and household power charging and has overcharge and over-discharge protection.

[0020] The above-mentioned explosion-proof barrier-type personnel static protection compliance confirmation instrument ensures the integrated design of static elimination and static compliance confirmation in the new static electricity management mode through the familiar and habitual application of the explosion-proof barrier-type structure by personnel. It ensures the anti-static or conductive function of the exposed clothing before the staff enters the static electricity dangerous area, and conducts a compliance confirmation on the electrical continuity of the clothing on each part of the human body, and confirms that the personnel are continuously grounded during walking, so as to ensure the management and monitoring of the personnel static protection measures in chemical plants, chemical storage and transportation, outdoor temporary operation areas for refining, synthesis, oil extraction, gas extraction, and explosion hazard areas. At the same time, by outputting a warning signal in a familiar voice prompt mode, it is confirmed whether the static protection measures of the personnel entering the static electricity dangerous area are qualified, avoiding fires caused by the failure of personnel's anti-static measures, and ensuring the safety and effectiveness of personnel static protection work.

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in the description of the present invention are only for the purpose of illustration and do not represent the only implementation manner.

[0029] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0030] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first feature is in direct contact with the second feature, or the first feature is in indirect contact with the second feature through an intermediate medium. Moreover, the first feature being "above", "over" or "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" or "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0031] Unless otherwise defined, all technical and scientific terms used in the description of the present invention have the same meaning as commonly understood by those skilled in the technical field to which the present invention pertains. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in the description of the present invention includes any and all combinations of one or more of the related listed items.

[0032] In the protection of personnel static electricity in various electrostatic hazard places of petrochemical, electronic products, and civil and military explosives, at the outside of the pump house door, at the upper tank ladder entrance and sampling port of the oil tank, at the ladder entrance and suspension ladder opening of the operating platform in the loading and unloading operation area, at the sampling port of the device area, at the dock entrance and other operation places, only explosion-proof human static eliminators are mostly installed. However, this type of equipment can only ensure that static electricity can be instantaneously released when a person touches it. But if the static electricity protection measures of the personnel's clothing are unqualified, for example, the resistance of the socks worn is too high, it will cause the anti-static shoes or conductive shoes that should comply with the national standard GB 21148-2020, and there is no electrical continuity in the clothing of each part of the human body. Although a conductive floor is used on the ground, the static electricity generated by instant friction cannot be released. Once static electricity accumulates and encounters static electricity discharge, it will seriously threaten the production safety of oil tankers, docks, port areas, loading and unloading areas, chemical plants, electronic products, and explosives filling.

[0033] For example, in production, there are often problems with external contractors wearing ordinary shoes instead of professional anti-static shoes on their feet, and some of the anti-static shoes issued by the factory have problems such as the sole falling off and wearing unqualified, which lead to the issue of whether static electricity can be safely released.

[0034] To avoid the occurrence of the above-mentioned dangers, before entering the static electricity hazard place, the static electricity protection measures of the personnel entering the anti-static work area should be confirmed, and they can enter only after being confirmed to be qualified and meeting the requirements.

[0035] There are also corresponding regulations and safety hazard warnings in national regulations, such as:

[0036] Article 11.1 of GB / T 3836.26-2019 "Guidelines for Static Electricity Hazards in Explosive Environments" stipulates that: "In a flammable environment with MIE less than 10 mJ, personnel should be grounded... and ensure that personnel wear dissipative shoes."

[0037] Article 5.10, Measures for the Release of Human Static Electricity, of SH / T 3097-2017 "Code for Design of Static Electricity Grounding in Petrochemical Industry" stipulates that: d) For the staff in static electricity hazardous areas, the exposed wearing items (including shoes and clothing) should have anti-static or conductive functions, and there should be electrical continuity among all parts of the wearing items.

[0038] Article 10.2 of GB12158-2024 "General Guidelines for Preventing Static Electricity Accidents"... and be equipped with safety shoes with anti-static or conductive functions that comply with the provisions of GB21148, and there should be electrical continuity among all parts of the wearing items. Article 10.5: Before entering a static electricity hazardous area, confirm the static electricity protection measures for the entering personnel, and they can enter only after meeting the requirements.

[0039] Therefore, there is an urgent need for a new type of device to be applied in static electricity hazardous areas, dangerous explosion operation areas, and to ensure the control, monitoring of static electricity protection measures for personnel in chemical plants, pharmaceutical factories, outdoor temporary operation areas such as refining, synthesis, oil extraction, gas extraction, and explosion hazardous areas, and the confirmation of static electricity protection measures for personnel. Ensure that before staff enter a static electricity hazardous area, they conduct a qualified confirmation of the anti-static or conductive functions of the exposed wearing items (including shoes and clothing) and the electrical continuity of all parts of the body's wearing items, and confirm that personnel are continuously grounded during walking.

[0040] The following combines Figures 1-3 Describe the explosion-proof gate-type personnel static electricity protection qualification confirmation instrument of the present invention.

[0041] As Figure 1 and Figure 2 shown, in one embodiment, an explosion-proof gate-type personnel static electricity protection qualification confirmation instrument can be used in gas explosion-proof zones 1 and 2, and dust explosion-proof zones 21 and 22, and can also be used in safety zones. The explosion-proof gate-type personnel static electricity protection qualification confirmation instrument includes an explosion-proof gate 100, an explosion-proof radar 200, an explosion-proof personnel static electricity protection confirmation instrument body 300, an explosion-proof voice alarm 400, an explosion-proof human body static electricity eliminator 500, and a metal footrest 600.

[0042] It should be supplemented and explained that the explosion-proof gate 100, the explosion-proof radar 200, the explosion-proof personnel static electricity protection confirmation instrument body 300, the explosion-proof voice alarm 400, and the explosion-proof human body static electricity eliminator 500 itself have independent national explosion-proof certification certificates and can be used in the explosion-proof areas and scopes permitted by the national certification certificates.

[0043] The explosion-proof barrier gate 100 is used to control the opening and closing of personnel passage, and the explosion-proof barrier gate 100 has conventional barrier gate functions, such as face recognition, fingerprint recognition, camera recording and other functions.

[0044] It should be added that the explosion-proof barrier gate 100 can be used in areas with dangerous gases and dangerous dust, and is modularly designed, easy to disassemble and move. It can have an IP66 protection level, be waterproof and corrosion-resistant. The explosion-proof barrier gate 100 is internally equipped with a professional static grounding clamp and a special anti-static cable, which is convenient for on-site operation and static grounding.

[0045] The explosion-proof radar 200 is installed on the explosion-proof barrier gate 100, and the explosion-proof radar 200 is used for the identification of personnel or items coming out of the explosion-proof barrier gate 100 and the interlocking of the opening and closing of the explosion-proof barrier gate 100.

[0046] The explosion-proof personnel static protection confirmation instrument body 300 is installed on or beside the explosion-proof barrier gate 100, and the explosion-proof personnel static protection confirmation instrument body 300 is used to detect whether the static grounding resistance of static safety shoes and facilities such as anti-static clothing and anti-static gloves worn by personnel is qualified.

[0047] It should be added that the resistance detection range of the explosion-proof personnel static protection confirmation instrument body 300 is 0 - 10 9 Ω, and the detection range can be adjusted according to the actual application scenario. The explosion-proof personnel static protection confirmation instrument body 300 can be mobile or fixed. At the same time, the explosion-proof personnel static protection confirmation instrument body 300 has a sealed waterproof function and can be used in field work sites that often encounter bad weather such as heavy rain.

[0048] The explosion-proof voice alarm 400 is installed on or beside the explosion-proof personnel static protection confirmation instrument body 300, and the explosion-proof voice alarm 400 is used for voice prompt and voice alarm.

[0049] The explosion-proof human body static eliminator 500 is installed on the explosion-proof personnel static protection confirmation instrument body 300, and the explosion-proof human body static eliminator 500 is used to release human body static electricity, detect static voltage and detect by hand touch.

[0050] It should be added that the explosion-proof human body static eliminator 500 has an accurate static voltage detection function. It can not only eliminate the static electricity carried by human touch, but also record the static voltage carried by the human body and the static discharge effect after elimination, whether it is close to 0V. If the static voltage is still high after static electricity elimination and exceeds the predetermined threshold (such as 100V), it can give a real-time alarm.

[0051] The metal foot pedal 600 is electrically connected to the detection interface of the explosion-proof personnel static electricity protection confirmation instrument body 300, and the metal foot pedal 600 is used for the anti-static shoes worn by personnel to step on.

[0052] It should be supplemented that the metal foot pedal 600 is made of stainless steel material, and its width is slightly narrower than the size of the feet when the human body stands with the feet slightly together. The maximum foot size can reach size 42 to suit personnel with large shoe sizes. And it is equipotentially connected to the nearby grounding busbar to ensure that the static electricity discharge channel of the human body is directly connected to the grounding busbar that is conducted to the ground, ensuring the safety and reliability of the static electricity release channel.

[0053] This explosion-proof gate-type personnel static electricity protection qualification confirmation instrument ensures the integrated design of static electricity elimination and static electricity qualification confirmation in the new static electricity control mode by the familiar and habitual application of the explosion-proof gate 100 structure by personnel. It ensures the anti-static or conductive function of the exposed clothing worn by the staff before entering the static electricity dangerous area, and conducts a qualified confirmation on the electrical continuity of the clothing worn on each part of the human body. It ensures that the personnel are continuously grounded during walking to ensure the control and monitoring of the personnel static electricity protection measures in petrochemical plants, petrochemical storage and transportation, pharmaceutical factory production, outdoor temporary operation areas and other refining, synthesis, oil extraction, gas extraction, and explosion hazardous areas. At the same time, it confirms whether the static electricity protection measures of the personnel entering the static electricity dangerous area are qualified by outputting a warning signal in a familiar voice prompt mode, avoiding fires caused by the failure of personnel's anti-static measures, and ensuring the safety and effectiveness of personnel static electricity protection work.

[0054] In this embodiment, the metal foot pedal 600 is equipotentially connected to the grounding pile of the earth. The metal foot pedal 600, the grounding pile, the human body, and the static electricity protection measures worn by the human body (such as anti-static shoes, anti-static clothing, anti-static gloves) jointly form a detection circuit on the explosion-proof personnel static electricity protection confirmation instrument body 300.

[0055] In this embodiment, see Figure 2 , the explosion-proof personnel static electricity protection confirmation instrument body 300 also has a main control board 310 and a display panel 320. The main control board 310 has a controller 330, and the display panel 320 has an LED status indicator 321 and a digital tube or a liquid crystal screen 322. The controller 330 is used to process the static electricity resistance on the detection circuit and transmit the detection result to the digital tube or the liquid crystal screen 322.

[0056] In this embodiment, see Figure 3, the controller 330 includes a receiving module 331, a signal driving module 332, a communication module 333, and a display module 334. The receiving module 331 is used to receive the static electricity resistance data of the detection loop in real time. The signal driving module 332 is used to instruct the explosion-proof voice alarm 400 to give an alarm. The display module 334 is used to output information on whether the static electricity protection is qualified in response to the static electricity resistance data on the detection loop being within the first threshold range. The communication module 333 is used to transmit the detection result and the alarm information to an external monitoring system and support remote control of the opening and closing of the explosion-proof barrier gate 100.

[0057] It should be supplemented that the first threshold is a static electricity resistance value of 100 KΩ to 1000 MΩ or 0 - 100 KΩ, or adjustable according to the actual application scenario. When the resistance value is not within the range of 100 KΩ to 1000 MΩ or 0 - 100 KΩ, an alarm is given.

[0058] In this embodiment, the communication module 333 can be wired or wireless, and the communication module 333 is an RS485 or LORA communication module.

[0059] In this embodiment, the signal driving module 332 includes an output unit 335 and an instruction unit 336. The output unit 335 is used to output an instruction signal in response to the static electricity resistance data on the detection loop exceeding the set threshold. The instruction unit 336 is used to instruct the explosion-proof voice alarm 400 to give an alarm and interlock the explosion-proof barrier gate 100 to open and close based on the instruction signal.

[0060] By outputting a warning signal to confirm whether the static electricity protection measures of the personnel entering the static electricity dangerous area are qualified, it is possible to avoid fires caused by the failure of the personnel's anti-static measures. At the same time, by interlocking the explosion-proof barrier gate 100 to open and close through the warning signal, it is ensured that the personnel's static electricity protection work is safe and effective.

[0061] In this embodiment, the controller 330 further includes a data storage module 337. The data storage module 337 is used to record the resistance value, timestamp, and operator identity information of each detection and support data export and analysis.

[0062] In this embodiment, the explosion-proof human body static eliminator 500 includes a touch button 510 and a static electricity release ball 520. The touch button 510 is built with a contact sensor, and the touch button 510 is used to detect the contact of a human hand and activate the static electricity release ball 520 to work.

[0063] It should be supplemented that the explosion-proof human body static eliminator 500 is also equipped with a static electricity voltmeter, which facilitates indicating whether the static electricity elimination result is qualified more intuitively through the display of the static electricity voltmeter, improving the safety performance.

[0064] In this embodiment, the explosion-proof personnel static electricity protection confirmation instrument body 300 is built-in with an explosion-proof battery 340 and a power management module 350. The power management module 350 supports solar charging and conventional industrial and household power charging, and has overcharge and over-discharge protection.

[0065] It should be added that the explosion-proof battery 340 can be used in gas explosion-proof zones 1 and 2, dust explosion-proof zones 21 and 22, and safe zones.

[0066] This explosion-proof barrier-type personnel static electricity protection qualification confirmation instrument can be applied to the entrances of petrochemical plants, hazardous chemical storage and transportation, and dangerous goods production workshops, as well as outdoor operation areas without power supply, to ensure the control and monitoring of personnel static electricity protection measures in the production of hazardous chemicals, the storage and transportation of hazardous chemicals, oil and gas production in outdoor temporary operation areas, and explosion-hazardous areas.

[0067] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0068] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
