Description

Technical Field

[0001] The present invention relates to the technical field of monitors, and more specifically to a multi-risk intelligent monitor for confined space operations. Background Art

[0002] Confined spaces generally refer to areas with restricted access, poor ventilation, or internal environments that are difficult to monitor, such as sewers, storage tanks, pipelines, etc. Due to the complex spatial environment, wide distribution, and diverse hazard sources in these areas, operation safety faces great challenges. During confined space operations, accidents such as poisoning, asphyxiation, explosion, drowning, and falling often occur. The occurrence of these accidents not only involves a single risk source but may also form cascading accidents due to the coupling and chain reaction of multiple risk factors, increasing the difficulty of risk prevention and control. Therefore, realizing the advanced detection, real-time monitoring, and reliable early warning of risks in confined space operations is the key means to prevent accidents.

[0003] Currently, various types of sensors are usually used to monitor risk factors such as harmful gases, hypoxia, temperature and humidity, and dust concentration in confined spaces in real time. However, the potential risks of different types of confined spaces vary, so the types and quantities of sensors required are also different. If multiple sensors are directly installed on the monitoring device, there will be a problem of "some sensors being idle", which not only affects the service life of the sensors but also makes the surface wiring of the device messy, increasing the difficulty of maintenance and repair and affecting the reliability and usability of the device.

Detailed implementation manner

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Embodiment:

[0038] Please refer to Figures 1 - 10 , a multi-risk intelligent monitor for confined space operations, including a cylinder body 1. As Figure 2 shown, a number of cut-off layers 4 are provided on the cylinder body 1. The cut-off part of the cut-off layer 4 is supported by a number of support columns 5, and a number of wing plates 6 are movably and telescopically arranged in the wing grooves separated by the number of support columns 5, and a telescopic rod 7 is fixedly installed on the inner side. As Figure 4 shown; in this embodiment, there are two upper and lower cut-off layers 4. Each cut-off layer 4 is supported by eight support columns 5. The eight support columns 5 divide the cut-off layer 4 into eight wing grooves, and a wing plate 6 is provided in each wing groove; of course, for those skilled in the art, the number of cut-off layers 4 and support columns 5 can also be increased or decreased according to needs.

[0039] A number of wing plates 6 are arranged in a ring. The sensor is installed in the mounting groove 8 provided on the telescopic rod 7 to realize the monitoring function. For confined spaces with different monitoring requirements, the telescopic rods 7 at different positions can be controlled to extend (such as the upper layer or the lower layer), while the remaining telescopic rods 7 and sensors are still in the retracted state, which not only ensures the monitoring effect, but also protects the remaining sensors, avoids unnecessary exposure of the sensors, and prolongs the service life of the sensors.

[0040] As Figure 6 and Figure 8 shown, the telescopic rod 7 is slidably arranged in the sliding groove 10. The sliding groove 10 is opened at the top of the sliding plate 9, and the sliding plate 9 is fixedly installed on the inner wall of the cylinder body 1. The telescopic rod 7 can be guided and directed to expand and contract through the sliding plate 9.

[0041] As shown Figure 6 in the figure, a sliding column 11 is fixedly installed at the top of the inner end of the telescopic rod 7. The sliding column 11 is slidably arranged in an arc-shaped guiding groove 12. The arc-shaped guiding groove 12 is opened on a driving disk 13. The driving disk 13 is rotatably installed in the cylinder body 1 through a bearing. Thus, by controlling the rotation of the driving disk 13 and guiding the sliding column 11 through the arc-shaped guiding groove 12, the telescopic rod 7 can be controlled to expand and contract.

[0042] In this embodiment, as shown Figure 6 and Figure 7 in the figure, a central groove 14 is opened at the center of the driving disk 13. The inner wall of the central groove 14 is evenly provided with spline grooves. It further includes a driving sleeve 15, which is vertically sleeved on a vertical cylinder 16 rotatably installed in the cylinder body 1, and the outer wall is evenly provided with splines corresponding to the spline grooves. By engaging the splines in the spline grooves, when the vertical cylinder 16 rotates, the driving disk 13 can also be driven to rotate through the driving sleeve 15, thereby controlling the expansion and contraction of the telescopic rod 7; for the specific rotation driving mode of the vertical cylinder 16, those skilled in the art can freely choose, such as the direct drive mode of a motor.

[0043] Furthermore, as shown Figure 7 in the figure, a lead screw 17 is also rotatably installed inside the vertical cylinder 16. A nut 18 is threadedly connected to the outer wall of the lead screw 17. The nut 18 is fixedly connected to the driving sleeve 15 through a connecting block. When the lead screw 17 rotates, the nut 18 threadedly connected to its outer wall will move up and down. The up and down movement of the nut 18 can drive the driving sleeve 15 to move up and down through the connecting block, so that the driving sleeve 15 corresponds to the driving disks 13 at different positions to drive the telescopic rods 7 at different heights to expand and contract; for the driving mode of the lead screw 17, a motor can also be used, which is not further limited in the present invention.

[0044] Thus, in the present invention, when it is necessary to control which layer of the telescopic rod 7 extends, first adjust the position of the driving sleeve 15, and then drive the entire vertical cylinder 16 to rotate.

[0045] As shown Figure 5 and Figure 10 in the figure, a positioning groove 19 is also opened at the top of the sliding column 11. A positioning ball 20 is movably clamped in the positioning groove 19. The positioning ball 20 is arranged at the bottom of a positioning ring 21. The positioning ring 21 is fixedly installed on the inner wall of the cylinder body 1. When the telescopic rod 7 extends to the maximum distance, the positioning groove 19 on the sliding column 11 just corresponds to the positioning ball 20 at the bottom of the positioning ring 21. By engaging the positioning ball 20 in the positioning groove 19, the stability of the telescopic rod 7 after extension can be further ensured. At this time, even if the position of the driving sleeve 15 is adjusted up and down, the telescopic rod 7 can still ensure stable extension; thus, through the design of the positioning ball 20, multiple layers of telescopic rods 7 can extend simultaneously;

[0046] In order to prevent the positioning ball 20 from blocking the normal movement of the sliding column 11 , the entire positioning ring 21 is made of plastic material and can produce a certain deformation to allow the positioning ball 20 to pass through.

[0047] Furthermore, regarding the power supply of the sensor in the installation groove 8, the positioning ball 20 and the positioning groove 19 can be used, and the power supply contacts can be respectively set on the positioning ball 20 and the positioning groove 19. Only when the positioning ball 20 is stuck in the positioning groove 19, the power supply of the sensor is turned on. This can significantly extend the service life of the sensor and prevent the sensor from being kept in the powered state and causing aging.

[0048] like Figure 8 and Figure 9 As shown, an inner cavity 24 is also formed inside the slide plate 9, and a piston 23 is movably arranged in the inner cavity 24. The piston 23 is fixedly connected to the wing plate 6 through a connecting rod 22. An air inlet nozzle 25 is arranged on one side of the inner cavity 24, and a one-way air inlet valve is arranged in the air inlet nozzle 25. The other side of the inner cavity 24 is connected to a gas nozzle 26 through a thin tube with a one-way exhaust valve. The gas nozzle 26 is arranged in the slide groove 10 and is inclined toward the telescopic rod 7. When the telescopic rod 7 and the wing plate 6 are extended, the wing plate 6 will also drive the piston 23 to move through the connecting rod 22. The piston 23 moves through the air inlet nozzle 25 and can inhale external air into the inner cavity 24; when the telescopic rod 7 and the wing plate 6 are retracted and reset, the movement of the piston 23 can make the air in the inner cavity 24 be ejected through the gas nozzle 26, and the air ejected by the gas nozzle 26 is sprayed below the telescopic rod 7 and the sensor, so that the sensor probe can be cleaned by air blowing to keep the sensor clean, so that the sensor can be automatically cleaned when it is stored after each use.

[0049] In the present invention, Figure 2 As shown, two mounting seats 2 are relatively installed on the top of the cylinder 1, and a rotating plate 3 is rotatably installed between the two mounting seats 2. The angle of the rotating plate 3 can be controlled by a steering gear. A reserved groove is provided on the rotating plate 3 for installing common devices such as cameras, fill lights, and visible light sensing chips, further enriching the functions of the monitor.

[0050] like Figure 3 As shown, a cooling fan 30 is also installed at the bottom of the cylinder 1 to dissipate heat from the components inside the cylinder 1 to maintain a good working condition.

[0051] In the present invention, the sensor includes but is not limited to a gas concentration detector, a temperature and humidity sensor, a barometer, a gyroscope, a laser ranging sensor and the like.

[0052] like Figure 1As shown, the entire cylinder 1 can be supported by a bracket 27 to achieve monitoring. For deeper spaces, a detection guide rod 28 can be screwed into a threaded opening 29 at the bottom of the cylinder 1, and the detection guide rod 28 can be inserted into the deeper space to achieve monitoring (a sensor is provided at the bottom end of the detection guide rod 28).

[0053] In the present invention, the cylinder 1 adopts an explosion-proof shell, which further improves safety.

[0054] The present invention can be applied to limited spaces such as underground warehouses, deep foundation pits, cellars, inspection wells, biogas pools, sewage treatment pools, fermentation pools, pulp pools, granaries, silos, storage tanks, reaction towers, kilns, pipelines, boilers, etc. It can also be extended to the fields of petroleum, chemical industry, metallurgy, electric power, as well as environmental monitoring, pollution control, laboratory safety prevention and control, and public safety.

[0055] like Figure 1 As shown, the information monitored by the monitor is transmitted to the risk analyzer, and the risk analyzer then transmits the data to the mobile terminal and the remote control platform through the server, thereby achieving the purpose of remote monitoring and remote command. The control system can be configured on the monitor, and the control system integrates functions such as voice call module, wireless transmission module, and sound and light alarm module. The voice of external detection personnel can be received in time through the voice call module, and the monitoring data can be uploaded to the risk analyzer in real time through the wireless transmission module and the risk identification information of the risk analyzer can be received. In case of danger, the sound and light alarm module can actively send out sound and light alarms... The specific system construction can be arranged by technicians in this field according to actual needs.

[0056] In the present invention, through the integration of multiple sensors, multiple functions such as "explosion gas concentration perception, oxygen gas concentration perception, spatial structure information perception, water body water level information perception, thermal infrared temperature perception, high voltage near-electricity perception, and pyrolysis particle perception" can be realized to be applicable to different types of limited spaces;

[0057] The risk analyzer can adopt relevant algorithms and use the data collected by sensors to evaluate various risks such as "poisoning, suffocation, explosion, scalding, falling, collapse, and electric shock". Based on the evaluation data, it can issue an audible and visual alarm and transmit it to the terminal device.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
