Description

Technical Field

[0001] The utility model relates to the fields of safety engineering and special operations, is applied to a limited space operation process, and specifically relates to a limited space operation vehicle. Background Art

[0002] In the daily operation of current industrial and trade enterprises, confined space operations, as a routine but highly dangerous activity, frequently cause safety accidents and attract widespread social attention. Such working environments usually include unfinished underground parking lots, closed containers, narrow pipes and various underground facilities. Their common characteristics are limited space, poor natural ventilation, easy accumulation of toxic and harmful gases, insufficient light, and narrow entrances and exits, which greatly increase the complexity and potential risks of operations.

[0003] Despite increasingly stringent safety regulations, there are still a series of challenges in actual operations, mainly reflected in the following aspects:

[0004] 1. Lack of professional equipment and poor management: There is a shortage of professional equipment for confined space operations on the market. Existing equipment often has single functions and is used in a decentralized manner. There is a lack of a unified management and maintenance system, making it difficult to form a systematic safety protection network.

[0005] 2. Lag in gas detection and ventilation control: Traditional gas detection equipment is mostly stand-alone operation, with isolated data that cannot be transmitted to the central control system in real time. As a result, the concentration monitoring of toxic and harmful gases and the automatic adjustment of the ventilation system cannot be effectively linked, posing significant safety hazards.

[0006] 3. Lack of vital signs monitoring: In high-risk working environments, there is a lack of life safety monitoring mechanisms for workers, and they are unable to provide timely warnings of abnormal health conditions, which increases the difficulty and delay of emergency rescue.

[0007] 4. Lack of integrated operation platforms: There are few limited space operation vehicles on the market that integrate multiple functions such as gas detection, ventilation control, and vital signs monitoring. This leads to cumbersome on-site layout and slow response, making it difficult to achieve rapid and efficient emergency response.

[0008] 5. Communication and information island problems: Information communication between ground monitoring and underground operations is not smooth. Single-machine gas detectors can only alarm on the spot and cannot immediately convey dangerous situations to ground monitoring personnel, affecting the timeliness of emergency evacuation and rescue operations.

[0009] 6. Insufficient energy management and early warning: Existing gas detection equipment generally ignores power monitoring and low power warning functions, which may cause equipment failure at critical moments and increase operational risks.

[0010] 7. Limitations of operation process management: Current operation process management mostly relies on manual records and on-site supervision, and lacks digital management tools, making process monitoring difficult, traceability poor, and difficult to efficiently implement safety management standards.

[0011] In summary, in order to address the problems existing in confined space operations, such as insufficient equipment integration, defects in monitoring and ventilation linkage, lack of life safety protection, poor information communication, backward energy management, and inefficient process management, an innovative technical solution is urgently needed to comprehensively improve the safety and efficiency of confined space operations through integrated and intelligent means, and fill the gaps in existing technologies and management practices.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1

[0042] like Figure 1 As shown, a limited space working vehicle comprises a movable vehicle body and a carriage 5, a cockpit 1 is arranged in front of the vehicle body, and the carriage 5 is arranged behind the cockpit 1. The carriage 5 is divided into a host cabinet 8, a backup power cabinet 3 and a first general cabinet 10, a control platform host 7 is installed in the host cabinet 8, and a plurality of portable slaves 16 are stored in the first general cabinet 10; the control platform host 7 is wirelessly connected with the portable slave 16 and the ground monitoring station respectively, and a gas concentration sensor is integrated in the portable slave 16.

[0043] Combination Figure 2 In this embodiment, the carriage 5 is further divided into a second universal storage cabinet 11. The first universal storage cabinet 10 and the second universal storage cabinet 11 each include one or more of a ventilation fan storage cabinet, a portable cable storage cabinet, a safety tool storage cabinet, a work tool storage cabinet, a breathing equipment storage cabinet and an emergency first aid storage cabinet.

[0044] Figure 1 and Figure 2The optimal layout of the above-mentioned cabinets is given, that is, the main cabinet 8 is arranged at the upper left side of the carriage 5, and the backup power cabinet 3 is arranged at the lower left side of the carriage 5; the first general cabinet 10 is arranged at the rear side of the carriage 5, and the second general cabinet 11 is arranged on the right side of the carriage 5; the remaining space inside the carriage 5 can be used to arrange relevant cable routing and electrical equipment according to actual needs.

[0045] In this embodiment, the carriage 5 can be used as an integrated platform for various tools in the limited space operation process, avoiding the problem of scattered tools and difficult management in traditional limited space operations. In addition, the work vehicle can have the wireless remote transmission function of toxic and harmful gas detection data with the support of hardware foundation. Its design concept is "master-slave, one-to-many". The control platform host 7 is integrated into the work vehicle body, and Figure 5 The portable slave 16 shown is carried by the operator. The portable slave 16 transmits the toxic and harmful gas detection data to the control platform host 7 through its gas concentration sensor, realizing real-time detection and early warning of the data. In this embodiment, it is recommended that one control platform host 7 be matched with and can be connected to five portable slaves 16 at the same time.

[0046] In this embodiment, the methods and control programs involved in the remote transmission of communication data of the control platform host 7 to the portable slave 16 and the communication connection with the ground monitoring station are mature technologies in the field, and the program logic is simple. Those skilled in the art can select and set them according to actual needs, and they will not be repeated here.

[0047] In this embodiment, the first universal storage cabinet 10 and the second universal storage cabinet 11 on the carriage 5 together constitute a flexible, highly organized and specialized storage system, thereby smoothly optimizing the efficiency and safety of the use of resources required for limited space operations, wherein:

[0048] The ventilation fan cabinet is stored as Figure 4 The ventilation fan 15 is shown, and the ventilation fan 15 is electrically connected to the control platform host 7. In confined space operations, the ventilation fan 15 can be used for replacement or continuous ventilation to reduce the concentration of toxic and harmful gases in the confined space, ensure sufficient oxygen, and provide a safe breathing environment for operators. In addition, the control platform host 7 can adjust the air volume of the ventilation fan 15 in combination with the toxic and harmful gas detection data fed back by the portable slave 16, and comprehensively balance the effect demand and resource consumption.

[0049] Portable cable storage cabinets are used to store various types of power cables and extension cords, providing necessary power support for the work site, such as lighting, power supply for instruments and equipment, etc., to ensure reliable supply and transmission of power during the operation.

[0050] Safety tool storage cabinets are used to store various personal protective equipment and safety auxiliary tools, such as safety helmets, protective glasses, protective clothing, safety ropes, fall prevention devices, etc. These are basic equipment to ensure the safety of workers.

[0051] The work tool storage cabinet is used to store specific tools required for the work, such as screwdrivers, wrenches, cutting tools, testing instruments, etc., to ensure that the work team can quickly and orderly access to the required tools and improve work efficiency.

[0052] Respiratory equipment storage cabinets are designed to store respiratory protection equipment, including self-contained breathing apparatus, air-supplied breathing apparatus, etc., to ensure better protection of workers' respiratory safety when working in toxic and harmful gas environments.

[0053] The emergency first aid storage cabinet is equipped with first aid kits, stretchers, AED defibrillators and other emergency medical supplies to deal with possible accidental injuries at the work site, provide initial medical assistance, and buy time for the arrival of professional rescue.

[0054] Through this type of layout, the work vehicle of this embodiment can quickly respond to various needs of confined space operations, ensuring that preparations before operations, safety protection during operations, and rapid response in emergency situations are properly arranged, which effectively improves the safety and efficiency of confined space operations.

[0055] In this embodiment, the portable slave 16 is also integrated with an audible and visual alarm and a power detector. The audible and visual alarm is electrically connected to the gas concentration sensor in the portable slave 16 where it is located. When the gas concentration directly detected by the portable slave 16 exceeds its preset threshold, the audible and visual alarm warns the operator currently carrying the slave and asks him to move to eliminate the potential safety hazard. The power detector is used to detect the power of the portable slave 16 where it is located, and also warns the operator currently carrying the slave when the power is low. The slave logic and programs involved in these two application processes are also mature technologies in this field, which can be designed and selected as needed, and will not be repeated here.

[0056] Example 2

[0057] On the basis of Example 1, Figure 3 As shown, in this embodiment, a plurality of groups of storage batteries 14 are installed in the backup power storage cabinet 3, and the storage batteries 14 are connected to the limited space working tools / equipment through a plurality of charging and discharging interfaces 2 provided on one side of the backup power storage cabinet 3, and the storage batteries 14 are also connected to the external mains power supply through the charging and discharging interfaces 2. A lock 4 is provided on the cabinet door of the backup power storage cabinet 3.

[0058] The configuration of the storage battery 14 is intended to provide a stable and reliable source of power for the confined space operation site. Since confined space operations are often carried out in remote areas or without a fixed power supply, configuring multiple groups of storage batteries 14 can ensure that the power demand for long-term operations is met, and also provide a guarantee for emergency power in unexpected situations.

[0059] The design of multiple charging and discharging interfaces 2 allows the operation team to quickly and conveniently power the operation equipment or charge the battery according to actual needs, which is convenient for daily maintenance and energy management. Due to the compatibility with external mains power, when there is mains power, the equipment or tools can also be powered directly, reducing the dependence on the battery 14, extending its service life, and reducing the operation cost.

[0060] Taking into account the safety requirements of the work site and the importance of electric energy resources in limited space operations, the purpose of providing a lock 4 on the door of the backup power storage cabinet 3 is to prevent unauthorized access or misoperation and ensure that the battery is protected from interference from the external environment, thereby further improving the safety level of the work site.

[0061] Example 3

[0062] Based on any of the above embodiments, Figure 1 As shown, the control platform host 7 of this embodiment has a host display screen, and a window is provided on the door of the host storage cabinet 8; when the door of the host storage cabinet 8 is closed, the position of the window corresponds to the position of the host display screen. In addition, a camera 9 is also provided on the carriage 5, and the camera 9 is electrically connected to the control platform host 7. The control platform host 7 has a built-in memory, and the memory stores camera image data and limited space operation data.

[0063] By controlling the host 7 of the platform, combined with the limited space operation data it contains and the host display screen, functions such as operation approval process management can be realized, and the pre-operation training, technical disclosure, gas concentration data recording during the operation, and post-operation site recovery involved in the limited space operation process can be managed throughout the process. In addition, the camera 9 on the carriage 5 can use a high-definition camera to shoot and record the relevant image data of the above process, which is convenient for the summary of the operation and process traceability.

[0064] In this embodiment, Figure 2 As shown, the top height of the carriage 5 is higher than the top height of the cockpit 1, and a carriage display screen 12 is also provided on the front side wall surface of the carriage 5 in an area higher than the top height of the cockpit 1; the carriage display screen 12 is electrically connected to the control platform host 7. In addition, an audible and visual alarm light 6 is also provided on the carriage 5, and the audible and visual alarm light 6 is electrically connected to the control platform host 7.

[0065] Both the carriage display screen 12 and the host display screen can display the gas concentration data, related information and warnings in real time and continuously, but the carriage display screen 12 is more eye-catching and convenient for operators to observe. When the feedback data from multiple portable slaves 16 are combined to determine that the concentration of toxic and harmful gases in the limited space reaches the limit of the control platform host 7, the control platform host 7 will immediately trigger and notify the ground monitoring station, and the sound and light alarm lamp 6 on the carriage 5 will broadcast an alarm to the area, prompting the operators to evacuate the on-site operation.

[0066] Example 4

[0067] On the basis of any of the above embodiments, the first universal storage cabinet 10 or the second universal storage cabinet 11 further stores a plurality of Figure 6 The monitoring bracelet 13 shown. The monitoring bracelet 13 is integrated with a vital sign sensor, which can monitor the key physiological indicators of the operator such as heart rate, blood oxygen saturation, body temperature, etc. in real time; the control platform host 7 is wirelessly connected to the monitoring bracelet 13. The monitoring bracelet 13 can be worn on the wrist of the current operator, and can monitor the vital signs of the operator in real time, and transmit the corresponding data back to the control platform host 7 to achieve remote monitoring.

[0068] In this embodiment, when there is any abnormality at the confined space operation site, such as a gas concentration alarm, the monitoring bracelet 13 can also cooperate with the sound and light alarm set in the portable slave 16 to jointly warn the operator. The ground monitoring station can also obtain the vital signs of each operator through the monitoring bracelet 13, and make relevant monitoring preparations in time when abnormal situations occur.

[0069] This type of real-time monitoring capability of this embodiment is crucial for preventing occupational health risks, especially in high-risk working environments such as confined spaces. It can ensure that supervisors can detect health abnormalities of workers at the first time, take timely intervention measures, and effectively reduce the accident rate.

[0070] To sum up, the confined space operation vehicle of the utility model fundamentally solves a series of pain points in confined space operations through a highly integrated and intelligent structural design. It not only improves the safety of operations, but also optimizes resource allocation through technological innovation and affects the improvement of operation processes, thereby providing a practical solution for industrial and trade enterprises and related fields.
