Description

Technical Field

[0001] The invention relates to the technical field of safety protection equipment, in particular to a multifunctional safety helmet for limited space. Background Art

[0002] In the extensive production and operation activities of power grid companies, confined space operations occupy a pivotal position. Such operations are widely found in confined spaces such as construction sites, production and operation areas, and underground pipeline corridors, cable tunnels, and inspection wells in office facilities. In such operating environments, the risk of serious injuries such as poisoning and suffocation is particularly prominent. If the relevant personnel are not equipped with appropriate safety protection equipment and lack the necessary emergency skills, blindly taking rescue actions is likely to escalate the initial accident into a more serious safety accident. Every year, power grid companies will issue management and control plans for personal risks, which clearly list confined space operations as one of the top ten or above personal accident risks that need to be focused on, and implement strict management and control measures.

[0003] Through in-depth analysis of multiple confined space operation accidents, we found that the main reason for the accidents was that the operators failed to strictly follow the operating procedures of "ventilation first, then testing, and then operation". In addition, the safety supervision department of the power grid company also revealed several key problems in the routine inspection of its subsidiaries and various construction projects: on the one hand, there are still a large number of operators who lack a clear understanding of the basic principle of "ventilation first, then testing, and then operation"; on the other hand, some confined space operation sites are not equipped with necessary detection instruments, which poses obvious safety hazards.

[0004] Given the huge amount of confined space operations that power grid companies need to perform each year, if operators neglect the detection link during the execution process, it is very easy to cause personal safety injuries and cause immeasurable losses.

[0005] Therefore, in response to current problems and challenges, we must comprehensively review and improve existing technologies to ensure the safety and efficiency of confined space operations.

[0064] Please refer to Figure 1-2 The embodiment of the present invention provides a multifunctional safety helmet for a limited space, comprising a safety helmet body 1, a processor 2, a toxic gas detection module 3 and an alarm module 4; wherein,

[0065] The processor 2 is arranged in the helmet body 1, serving as the intelligent core of the entire system, and is responsible for data processing and instruction sending;

[0066] A first installation slot is provided on the outer side of the helmet body 1, and this design is intended to facilitate installation and removal of functional modules to meet different operating requirements;

[0067] The toxic gas detection module 3 is detachably disposed in the first mounting slot and connected to the processor 2;

[0068] The toxic gas detection module 3 has a highly sensitive sensing technology for detecting whether there is toxic gas in the air and detecting the concentration of the toxic gas;

[0069] The processor 2 is used to determine whether the concentration of toxic gas exceeds the standard, and send an alarm instruction to the alarm module 4 when it exceeds the standard;

[0070] The alarm module 4 is used to issue an alarm after receiving the alarm instruction, which can effectively avoid potential casualties caused by negligent gas detection and provide solid protection and technical support for safe operations in limited spaces.

[0071] In summary, this embodiment integrates the processor 2, the toxic gas detection module 3 and the alarm module 4 into the helmet body 1 to construct an intelligent and efficient operation safety warning system, which greatly improves the safety level in a confined space operation environment.

[0072] In one implementation of the present embodiment, the design of the toxic gas detection module 3 takes into full account the various types of toxic gases that may be encountered in a limited space working environment. Therefore, it can be a module for detecting a single gas, such as a carbon monoxide gas detection module specifically used to detect carbon monoxide gas, a hydrogen sulfide gas detection module focused on hydrogen sulfide gas detection, or a methane gas detection module for accurately measuring methane gas. At the same time, in order to meet the needs of a more complex and changeable working environment, the toxic gas detection module 3 can also be a combination of the above-mentioned detection modules, that is, it can simultaneously detect and monitor the concentration of multiple toxic gases such as carbon monoxide, hydrogen sulfide, and methane. Such a design not only improves the comprehensiveness and accuracy of detection, but also greatly enhances the safety of operators in a limited space, ensuring that they can obtain accurate information about the gas composition and concentration in the working environment at the first time, so as to make correct judgments and countermeasures.

[0073] In one implementation of this embodiment, the design of the alarm module 4 fully considers the diversity and flexibility of the alarm signal receiving methods in different working environments. Specifically, the alarm module 4 can be a simple sound alarm module, which quickly attracts the attention of the operators by emitting a high-decibel alarm sound to ensure that they can perceive the potential dangerous situation at the first time. In addition, the alarm module 4 can also be a light alarm module, which uses eye-catching light flashing to convey alarm information, which is particularly important for operators working in noisy or hearing-impaired environments, because they may rely more on visual signals to receive alarms.

[0074] Furthermore, in order to meet the needs of more complex and changeable working scenes, the alarm module 4 can also be a combination of a sound alarm module and a light alarm module. Such a design can not only enhance the transmission effect of the alarm information through the dual signals of sound and light, and improve the vigilance of the operators to potential dangers, but also ensure that in any working environment, the operators can receive clear and definite alarm information, so as to take correct countermeasures in time to ensure their own safety.

[0075] In a more perfect implementation of this embodiment, the multifunctional safety helmet for limited space also creatively integrates a wearing detection module 5, further improving its safety performance and user experience. Specifically, the wearing detection module 5 is arranged on the inner side of the safety helmet body 1 and establishes a stable connection with the processor 2. The module uses advanced sensing technology to detect in real time and accurately whether the safety helmet body 1 is correctly worn by the operator.

[0076] When the wearing detection module 5 detects that the helmet body 1 has been worn, the processor 2 will automatically start a series of safety inspection procedures. Among them, a key inspection is to determine whether the toxic gas detection module 3 has been correctly connected to the processor 2. This step is crucial because it ensures that when the operator enters a potentially dangerous environment, the toxic gas detection module 3 can immediately start working and monitor the concentration of toxic gases in the air in real time.

[0077] If the processor 2 finds that the connection with the toxic gas detection module 3 is not established after detecting that the helmet is worn, it will immediately trigger the alarm process and send an alarm instruction to the alarm module 4. At this time, the alarm module 4 will send a striking alarm signal in a preset manner (such as sound alarm, light alarm or a combination of the two) to remind the operator to check the connection status of the toxic gas detection module 3, so as to determine whether the toxic gas detection module 3 is installed, so as to ensure that accurate and timely gas concentration monitoring information can be obtained during the operation.

[0078] Such a design not only enhances the intelligence level of the helmet, but also greatly improves the safety of workers when working in confined spaces. Through the coordinated work of the wearing detection module 5, the processor 2, the toxic gas detection module 3 and the alarm module 4, a complete and efficient safety monitoring system is formed, providing a solid guarantee for the life safety of the workers.

[0079] In a more comprehensive and detailed implementation of the present embodiment, the multifunctional safety helmet for confined space is innovatively expanded again, and an oxygen content monitoring module 6 is newly added, which further enhances its safety assurance capability in complex working environments.

[0080] Specifically, in order to accommodate and fix the oxygen content monitoring module 6, a second installation groove is specially designed and opened on the outer side of the safety helmet body 1. This groove is similar to the first installation groove, and both are designed to facilitate module installation and disassembly to adapt to changing needs in different working scenarios.

[0081] The oxygen content monitoring module 6 is firmly installed in the second installation slot through precise mechanical design and is electrically connected to the processor 2. The module uses advanced sensing technology to monitor the oxygen content of the air in the working environment in real time, ensuring that the operator can grasp the oxygen status of the current environment at any time.

[0082] As the intelligent core of the whole system, processor 2 once again demonstrates its powerful data processing and judgment functions. It can not only receive and process data from toxic gas detection module 3, but also quickly analyze the oxygen content information transmitted by oxygen content monitoring module 6. Once processor 2 determines that the oxygen content in the air is lower than the preset oxygen threshold, it will immediately trigger the alarm process and send an emergency alarm instruction to alarm module 4.

[0083] At this time, the alarm module 4 will send out a striking alarm signal in a preset manner (such as sound alarm, light alarm or a combination of the two) to remind the operator that the oxygen content in the current environment is insufficient, which may constitute a safety hazard. Such a design not only helps the operator to take timely countermeasures, such as evacuating the dangerous area or wearing an oxygen mask, but also effectively avoids physical discomfort or life-threatening situations caused by lack of oxygen.

[0084] In summary, by adding the oxygen content monitoring module 6, the multifunctional safety helmet for confined spaces of this embodiment further improves the comprehensiveness and accuracy of its safety protection on the original basis, and provides more reliable safety protection for operators in complex and changeable working environments.

[0085] In another innovative implementation of the present embodiment, the multifunctional safety helmet for confined spaces is further enriched in functionality by adding a lighting module 7 and a light sensing module 8, which provide necessary lighting support for operators in insufficiently lit environments, further improving its applicability and safety in various complex working scenarios.

[0086] Specifically, in order to install the lighting module 7, a third installation slot is specially designed and opened on the outer side of the helmet body 1. This slot is similar to the previous installation slot and is also designed to facilitate module installation and removal. The lighting module 7 is firmly installed in the third installation slot through precise mechanical design and is electrically connected to the processor 2. The module has a high-brightness lighting function and can provide a clear field of vision for operators in low-light environments.

[0087] At the same time, the light sensing module 8 is cleverly arranged on the outside of the helmet body 1, and a stable connection is established with the processor 2. The module uses advanced sensing technology to detect the light brightness in the working environment in real time and provide the processor 2 with accurate light information.

[0088] As the intelligent core of the whole system, processor 2 once again demonstrates its powerful data processing and judgment functions. It can not only receive and process data from toxic gas detection module 3 and oxygen content monitoring module 6, but also quickly analyze the light brightness information transmitted by light sensing module 8. Once processor 2 determines that the brightness of the ambient light is lower than the preset brightness threshold, it will immediately trigger the lighting process and send a lighting instruction to lighting module 7.

[0089] At this time, the lighting module 7 will respond quickly and start its high-brightness lighting function to clearly illuminate the area ahead. Such a design not only helps operators maintain a clear field of vision in an environment with insufficient light, improves work efficiency, but also avoids safety hazards caused by unclear vision.

[0090] In summary, by adding the lighting module 7 and the light sensing module 8, the multifunctional safety helmet for confined spaces of this embodiment further enhances its functional diversity and safety on the original basis, providing more comprehensive and reliable protection for operators in various complex working scenarios.

[0091] In a more advanced and practical implementation of the present embodiment, the multifunctional safety helmet for confined space is technically upgraded again, and a communication module 9 is added to realize the real-time communication function with the monitoring terminal, further improving its emergency response speed and safety in emergency situations.

[0092] Specifically, the communication module 9 is carefully arranged inside the helmet body 1 and establishes a stable connection with the processor 2. The module has a strong communication capability and can transmit the data and information generated by the processor 2 to the remote monitoring terminal in real time.

[0093] When the processor 2 determines that the concentration of toxic gas exceeds the standard, it will immediately generate an alarm data containing detailed alarm information. This alarm data not only contains key information such as the type and concentration of the toxic gas, but also may include important content such as the geographical location of the helmet and the identity information of the operator. The processor 2 will quickly send this alarm data to the communication module 9.

[0094] After receiving the alarm data, the communication module 9 will immediately start its communication function and send the alarm information to the preset monitoring terminal in the form of a wireless signal. This monitoring terminal may be the enterprise's security management center, emergency response team or the command center of the relevant regulatory department. After receiving the alarm information, the monitoring terminal will immediately respond and start the corresponding emergency plan, such as dispatching a rescue team, starting the emergency evacuation procedure, etc., to ensure the life safety of the operating personnel and the stability of the working environment.

[0095] This design not only improves the emergency response speed of the helmet in emergency situations, but also transmits the alarm information to the remote monitoring terminal in real time, providing strong technical support for the company's safety management and emergency response. At the same time, it also provides a more comprehensive and reliable guarantee for the life safety of operators when working in confined spaces.

[0096] In summary, by adding the communication module 9, the multifunctional safety helmet for confined spaces of this embodiment further improves its emergency response speed and safety on the original basis, providing a more powerful guarantee for the safety management of the enterprise and the life safety of the operators.

[0097] In a more cutting-edge and user-friendly implementation of the present embodiment, the multifunctional safety helmet for confined spaces has undergone another technological innovation, with a new audio and video interaction module 10 added to realize the audio and video remote interaction function with the remote monitoring terminal, further improving the level of information communication and safety management at the work site.

[0098] Specifically, the audio and video interaction module 10 is cleverly arranged on the outside of the helmet body 1, and establishes a stable connection with the processor 2 and the communication module 9. The module integrates audio and video acquisition and playback devices such as a high-definition camera, a microphone, and a speaker, and can capture video and audio information of the work site in real time, and transmit this information to a remote monitoring terminal through the communication module 9.

[0099] When the operator needs to interact with the remote monitoring terminal via audio and video, the processor 2 will start the relevant functions of the audio and video interaction module 10 and establish an audio and video communication connection with the remote monitoring terminal through the communication module 9. At this time, the operator can send voice information to the remote monitoring terminal through the microphone, and the high-definition camera will also capture the video image of the work site in real time and transmit it to the remote monitoring terminal through the communication module 9. After receiving this information, the remote monitoring terminal will immediately display and play it, so that the remote monitoring personnel can clearly see and hear the situation at the work site.

[0100] Similarly, the remote monitoring personnel can also send voice and video information to the audio and video interaction module 10 through the communication module 9, which will be received and processed by the processor 2, and then played to the operator through the speaker and display device. In this way, the operator can communicate with the remote monitoring personnel in real time through audio and video, share the situation at the work site, discuss solutions or receive remote guidance, etc.

[0101] This design not only improves the efficiency of information communication at the work site, but also allows remote monitoring personnel to understand the situation at the work site more intuitively, providing more comprehensive and intuitive information support for the company's safety management and emergency response. At the same time, it also provides a more powerful and convenient guarantee for the life safety and work efficiency of operators when working in confined spaces.

[0102] In summary, by adding the audio and video interaction module 10, the multifunctional safety helmet for confined spaces of this embodiment further improves its information communication capability and safety management level on the original basis, providing more comprehensive and reliable technical support for the enterprise's safety management and the life safety of operators.

[0103] In one implementation of this embodiment, the multifunctional safety helmet for confined spaces has been significantly expanded in functionality, with a new one-key help module 11, which provides workers with a quick and effective means of seeking help in emergency situations, further improving their safety level at the work site.

[0104] Specifically, the one-key help module 11 is carefully arranged on the outside of the helmet body 1 to ensure that the operator can quickly reach and trigger it with one key in an emergency. The module has established a stable connection with the processor 2. Once triggered, it will immediately generate a help request containing emergency help information and send it to the processor 2.

[0105] After receiving the request for help, the processor 2 will immediately start the emergency response process. On the one hand, it will send an alarm instruction to the alarm module 4, triggering the alarm module 4 to send out a conspicuous alarm signal, such as a sound alarm, a light alarm, etc., to attract the attention of the surrounding people and seek help. On the other hand, the processor 2 will also generate an alarm data containing detailed alarm information and send it to the communication module 9. This alarm data not only contains key information such as the identity information of the person seeking help and the geographical location of the helmet, but may also include important content such as the nature of the emergency and the description of the working environment.

[0106] After receiving the alarm data, the communication module 9 will immediately start its communication function and send the alarm information to the preset monitoring terminal or emergency rescue center in the form of a wireless signal. In this way, after receiving the alarm information, the monitoring terminal or the emergency rescue center can quickly understand the emergency situation at the work site and start the corresponding emergency plan, such as dispatching a rescue team, starting the emergency evacuation procedure, etc., to ensure the life safety of the operators and the stability of the working environment.

[0107] The design of the one-click help module 11 not only reflects the deep concern for the life safety of operators, but also provides faster and more effective technical support for the company's safety management and emergency response. It allows operators to get help quickly in an emergency, reducing the risk and consequences of accidents.

[0108] In summary, by adding the one-key help module 11, the multifunctional safety helmet for confined spaces of this embodiment further improves its safety level and emergency response speed on the original basis, providing more comprehensive and reliable protection for the life safety of operators.

[0109] In a specific and practical implementation of this embodiment, a Bluetooth module is selected as the implementation mode of the communication module 9. This selection is based on the wide popularity of Bluetooth technology, low power consumption, and its stability and reliability in short-range wireless communication.

[0110] The Bluetooth module is integrated inside the helmet and closely connected to the processor 2, ensuring fast and accurate data transmission. It not only enables wireless connection between the helmet and the remote monitoring terminal, but also supports pairing and communication with other Bluetooth devices, such as smartphones and tablets, providing operators with more communication and collaboration options.

[0111] The advantages of using a Bluetooth module as the communication module 9 are:

[0112] Low power consumption: Bluetooth technology is well known for its low power consumption characteristics, which is especially important for hard hats that need to be worn and used for a long time. Low power consumption means longer battery life, reduces the need for frequent charging, and improves the user experience of workers.

[0113] Short-range wireless communication: Bluetooth technology is suitable for short-range wireless communication, which is very suitable for limited space operation scenarios. Operators can communicate with nearby monitoring terminals or other Bluetooth devices through the Bluetooth module to ensure real-time transmission and sharing of information.

[0114] Wide compatibility: Bluetooth technology has been widely used in various smart devices and operating systems, so the Bluetooth module has good compatibility. This means that workers can easily connect the helmet with their smartphones, tablets and other devices to synchronize and share data.

[0115] Security: Bluetooth technology provides a variety of security features, such as encryption and authentication, to ensure the security and integrity of data transmission. This is especially important for alarm data containing sensitive information, which can prevent the data from being illegally intercepted or tampered with.

[0116] In summary, choosing the Bluetooth module as the implementation method of the communication module 9 not only meets the requirements of limited space operation scenarios, but also provides advantages in low power consumption, wide compatibility, and safety. This choice further improves the practicality and user experience of the helmet and provides more reliable technical support for the life safety of the operators.

[0117] Although the terms such as helmet body, processor, toxic gas detection module, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0118] A multifunctional safety helmet for confined spaces provided in an embodiment of the present invention has a processor, a toxic gas detection module and an alarm module arranged on the safety helmet body, so that when the toxic gas detection module detects the presence of toxic gas in the air and the processor determines that the concentration of the toxic gas exceeds the standard, the alarm module can sound an alarm to remind the operating personnel, thereby preventing casualties caused by the operating personnel's negligence in gas detection, and providing protection for on-site safe operations in confined spaces.

[0119] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application.
