Description

Technical Field

[0001] The invention relates to the technical field of safety equipment for confined space operations, and in particular to a continuous air supply type long tube respirator with air volume monitoring and alarm functions. Background Art

[0002] Confined space refers to a space that is closed or partially closed, with narrow and limited entrances and exits, is not designed as a fixed workplace, has poor natural ventilation, and is prone to accumulation of toxic, harmful, flammable and explosive substances or insufficient oxygen content. When working in such a space, there are many factors that threaten the life safety of workers due to poor air circulation. Among them, insufficient oxygen and inhalation of harmful gases are the most common risks. Therefore, when working in a confined space, it is crucial to provide workers with reliable respiratory protection equipment.

[0003] Traditional long-tube respirator blowers lack an air volume monitoring mechanism. Traditional long-tube respirator blowers are usually composed of components such as a blower, an air duct, a long tube, a respirator mask, a battery, and a switch. However, these blowers are often not equipped with an air volume monitoring device. In actual use, operators have no way of knowing whether the air volume output by the blower can meet their breathing needs. If the blower fails or the air volume decreases due to damage or blockage of the long tube, operators may be exposed to a dangerous environment with insufficient oxygen without knowing it.

[0004] Traditional long-tube respirator blowers cannot monitor the wearing status of the breathing mask. Existing long-tube respirator blowers cannot detect the wearing status of the breathing mask. During confined space operations, if the breathing mask is not worn correctly, for example, the mask is not tightly fitted to the face or the operator accidentally removes the mask during the operation, the blower will not be able to prompt this situation. This may cause the operator to inhale harmful gases in the confined space, causing serious safety accidents such as poisoning and suffocation.

[0005] Although similar gas monitoring or equipment status monitoring technologies may exist in some other fields, there is a lack of integrated technologies for air volume monitoring of long-tube respirator blowers and respiratory mask wearing status monitoring for confined space operations. Existing confined space operation respiratory support equipment has obvious technical shortcomings in ensuring the respiratory safety of operators. The defects of existing technologies are mainly reflected in the following three aspects:

[0006] 1. Air volume monitoring

[0007] No real-time monitoring

[0008] Traditional long-tube blowers lack the function of real-time monitoring of air volume. In confined space operations, due to the complex and changeable working environment, blowers may be affected by a variety of factors, such as mechanical failure of the blower itself, squeezing or blockage of the long tube, power supply fluctuations, etc. However, existing equipment does not have a device that can obtain the blower's air volume data in real time, and operators and supervisors cannot know in time whether the blower is working normally and whether the air volume is within a safe range.

[0009] Lack of risk warning

[0010] Because there is no air volume monitoring, there is no early warning signal when the air volume is insufficient. In a limited space, once the air volume is lower than the safety standard, toxic and harmful gases cannot be diluted and discharged in time, and the oxygen content will also decrease. Without any warning, the operator may continue to work, thus facing serious safety risks such as poisoning and suffocation, posing a great threat to the life safety of the operator.

[0011] 2. Monitoring of the wearing status of respiratory masks

[0012] Unable to monitor wearing status

[0013] The existing long-tube blowers and their matching respirator masks do not have the function of monitoring the wearing status. In actual operation, operators may wear the respirator mask improperly due to various reasons, such as the mask not fitting the face correctly, accidentally loosening or falling off during work, etc. However, due to the lack of monitoring means, these problems cannot be discovered in time.

[0014] Security vulnerabilities pose a great threat

[0015] When there is a problem with wearing a breathing mask, the operator will be directly exposed to the harmful gas environment in a limited space. Existing equipment cannot monitor and prompt this situation, which creates a huge safety loophole. The operator may not notice it after inhaling harmful gases until symptoms of poisoning appear, at which time irreparable damage may have already been caused to the body.

[0016] 3. Overall equipment safety and intelligence

[0017] Lack of linkage alarm mechanism

[0018] The long-tube blower and respirator mask under the existing technology are relatively independent. There is no system that can integrate air volume monitoring and respirator mask wearing status monitoring, and there is no linkage alarm mechanism when abnormal situations occur. This results in the inability to promptly and effectively notify operators and on-site supervisors when faced with safety risks, delaying the best time to take emergency measures.

[0019] Low level of intelligence

[0020] Traditional equipment is relatively simple in function, only providing air supply and basic respiratory protection. It does not use modern sensor technology and intelligent control technology to improve the safety and reliability of the equipment. With the continuous improvement of safety requirements for confined space operations, this low-intelligence equipment can no longer meet the needs of ensuring the safety of operators.

[0021] Therefore, there is an urgent need for a continuous air supply long-tube respirator with air volume monitoring and alarm functions. In view of the technical defects of the above-mentioned traditional long-tube respirator blower in confined space operations, by adding components such as wind speed sensors, wind speed transmitters, controllers and communication modules, the monitoring and alarm functions of the air volume and breathing mask wearing status are realized, aiming to ensure the life safety of workers in confined spaces. Summary of the invention

[0022] The purpose of the present invention is to provide a continuous air supply long tube respirator with air volume monitoring and alarm functions to solve the problems existing in the above-mentioned prior art.

[0023] To achieve the above object, the present invention provides the following solutions:

[0024] The present invention provides a continuous air supply long tube respirator with air volume monitoring and alarm functions, comprising a fan, wherein the fan is provided with an air duct, wherein the air duct is connected to a breathing mask through a long tube, wherein the fan is provided with a wind speed transmitter, an alarm component and a communication module, wherein a wind speed sensor is provided in the air duct, wherein the fan, the wind speed transmitter, the alarm component, the communication module and the wind speed sensor are all electrically connected to a controller, and the communication module is wirelessly connected to a remote monitoring system.

[0025] Preferably, the fan is provided with supporting feet at the bottom and a handle at the top.

[0026] Preferably, a battery is provided in the fan, and the battery is electrically connected to the controller.

[0027] Preferably, a power interface is provided on the outside of the fan, and the power interface is electrically connected to the battery.

[0028] Preferably, a control panel is provided on the side of the fan.

[0029] Preferably, the air duct is provided with a threaded interface.

[0030] Preferably, the alarm component includes a warning light and a buzzer.

[0031] Compared with the prior art, the present invention has achieved the following beneficial technical effects:

[0032] The continuous air supply long tube respirator with air volume monitoring and alarm function provided by the present invention solves the following problems:

[0033] 1. Lack of air volume monitoring

[0034] The existing long-tube blower products do not have a function for monitoring the air volume generated by the blower. This means that when working in a confined space, workers cannot know whether the air volume output by the blower is within a safe range. Once the air volume is insufficient, the workers may not be able to get enough fresh air, which may lead to safety risks such as suffocation. The present invention solves this key problem by adding a wind speed sensor, a wind speed transmitter and a controller to achieve real-time monitoring of the air volume in the long tube.

[0035] 2. The problem of the wearing status of the breathing mask cannot be monitored

[0036] The original product cannot detect whether the breathing mask is worn correctly. In actual operation, if the breathing mask is not worn correctly, for example, the mask does not fit the face and causes air leakage, or the operator does not wear the mask, the operator may be exposed to a dangerous environment. The present invention uses a wind speed sensor to judge the wearing condition of the breathing mask according to the change of air volume in the long tube, filling this technical gap.

[0037] The continuous air supply long tube respirator with air volume monitoring and alarm function provided by the present invention has the following advantages:

[0038] 1. Improved security

[0039] Insufficient air volume alarm: When the air volume generated by the blower is lower than the safe range, the controller and alarm module can promptly alert the staff. This allows the staff to take measures before the insufficient air volume causes danger, such as checking the blower failure or adjusting the working environment, thus greatly ensuring the breathing safety of the staff in the limited space.

[0040] Abnormal wearing alarm for breathing mask: It can accurately detect whether the breathing mask is worn correctly and issue an alarm prompt when it is worn incorrectly. This avoids the risk of workers being exposed to harmful environments due to breathing mask wearing problems and ensures the safety of construction workers.

[0041] 2. Intelligence and real-time monitoring

[0042] By adding wind speed sensors, controllers and communication modules, intelligent and real-time monitoring of the working status of long-tube blowers and the wearing status of breathing masks is realized. The controller can process and analyze the data collected by the wind speed sensor and make judgments based on the preset safety threshold. At the same time, the communication module can also transmit this data to external devices (such as monitoring centers), which facilitates remote management and data analysis and improves management efficiency.

[0048] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0049] Embodiment 1:

[0050] This embodiment provides a continuous air supply long tube respirator with air volume monitoring and alarm functions, such as Figure 1 and 2 As shown, the fan 1 includes an air duct 2, which is connected to a breathing mask 4 through a long tube 3. The fan 1 is provided with a wind speed transmitter 5, an alarm component 6 and a communication module 7. A wind speed sensor 8 is provided in the air duct 2. The fan 1, the wind speed transmitter 5, the alarm component 6, the communication module 7 and the wind speed sensor 8 are all electrically connected to a controller 9, and the communication module 7 is wirelessly connected to a remote monitoring system.

[0051] As an implementation mode, a support foot 11 is provided at the bottom of the fan 1, and a handle 12 is provided at the top thereof, so that the fan 1 can be stably supported and conveniently carried.

[0052] As an implementation mode, a battery 13 is provided in the fan 1, and the battery 13 is electrically connected to the controller 10, so that the fan 1 can be used independently without being restricted by the use of a power cord.

[0053] As an implementation mode, a power interface 14 is provided on the outside of the fan 1, and the power interface 14 is electrically connected to the battery 13, so as to facilitate charging.

[0054] As an implementation manner, a control panel 15 is provided on the side of the wind turbine 1 for display and control.

[0055] As an implementation mode, the air duct 2 is provided with a threaded interface for easy connection.

[0056] As an implementation mode, the alarm component 6 includes a warning light and a buzzer, and can provide audible and visual alarms.

[0057] The present invention provides a continuous air supply long tube respirator with air volume monitoring and alarm functions. A high-precision wind speed sensor is installed at the air duct of the blower. The wind speed sensor adopts advanced sensing technology and can accurately measure the wind speed data output by the blower in real time, and convert these data into electrical signals for transmission to the controller. Its measurement principle is based on the keen perception of air flow characteristics, ensuring that accurate and reliable wind speed measurement values ​​can be provided under different working conditions and air volume ranges, and the error range is controlled within a very small range, thereby providing a solid data foundation for subsequent air volume judgment and control; the controller, as the core control unit of the entire system, receives the electrical signal from the wind speed sensor and processes and analyzes it quickly. The controller is built with a specially developed intelligent control algorithm. The algorithm pre-sets the safety threshold range of the air volume based on the safety standard requirements for the air volume of the blower in limited space operations. When the air volume corresponding to the received wind speed data is lower than or higher than the preset safety threshold, the controller immediately starts the corresponding control instruction; the alarm is closely connected to the controller, and after the controller issues an alarm instruction, it quickly starts The alarm is designed with a combination of high-brightness warning lights and high-decibel buzzers. The warning lights can display lights of different colors under different abnormal circumstances. For example, red light is displayed when the air volume is insufficient, and yellow light is displayed when the breathing mask is worn abnormally, so that operators and on-site supervisors can intuitively identify the alarm type. The sound and light alarm emits a continuous and loud sound, which can be clearly heard even in a noisy working environment, ensuring that relevant personnel can detect abnormal situations in time and take corresponding emergency measures; the communication module monitors the wearing status of the breathing mask, realizes real-time and remote monitoring of the wearing status of the breathing mask, further improves the intelligence level and safety assurance capabilities of the entire system, and promptly detects personnel who violate construction regulations.

[0058] The continuous air supply long tube respirator with air volume monitoring and alarm functions provided by the present invention can be used in various confined space operation scenarios, such as internal maintenance of chemical storage tanks, municipal sewer dredging, power cable well construction, underground mine operations, etc., to provide safe and reliable breathing protection and real-time monitoring functions for operators; when the operator enters the confined space and turns on the equipment, the fan starts to operate, and fresh air is delivered to the breathing mask through the air duct and the long tube, ensuring that the operator can breathe sufficient and safe air. In this process, the wind speed sensor and the wind speed transmitter work together to accurately collect the wind speed data in the long tube, and then the controller converts the air volume information. Once the air volume is lower than the preset safety range, the controller immediately triggers the alarm module and sends out a clear and loud sound and light alarm signal to remind the staff that the air volume generated by the blower is insufficient, so as to timely check the operation status of the blower and whether the long pipe is unobstructed, so as to prevent the oxygen content in the confined space from decreasing and the accumulation of harmful gases due to insufficient air volume, thereby ensuring the breathing safety of the operators; at the same time, based on the monitoring principle of the change of air volume in the long pipe, the equipment can also judge whether the breathing mask is worn normally or whether it is worn. If the operator does not wear the breathing mask correctly, or the mask accidentally falls off or loosens during the operation, resulting in loss of air tightness, causing abnormal changes in the air volume in the long pipe, the controller will also drive the alarm module to issue an alarm prompt, so that the operator can quickly detect and correct the problem of wearing the breathing mask, avoid the operator from being exposed to toxic and harmful gas environments, effectively prevent the occurrence of serious safety accidents such as poisoning and suffocation, and effectively protect the life safety and health of the operators in the confined space during the entire operation process, and provide indispensable technical support and guarantee means for the smooth and safe development of confined space operations.

[0059] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
