Description

Technical Field

[0001] This utility model relates to the technical field of gas production safety monitoring equipment, specifically to a multi-level early warning sensor installation structure for gas production environment. Background Technology

[0002] In gas production environments (such as chemical synthesis, gas preparation, and special gas processing), leaks of toxic, flammable, and explosive gases can directly threaten personnel safety and the integrity of production equipment. Real-time monitoring and graded early warning of gas concentrations are core aspects of ensuring production safety. As a key carrier of the monitoring and early warning system, the performance of gas detection sensor installation structures directly determines the timeliness and reliability of early warning responses.

[0003] The sensors in existing gas sensing installation structures are mostly fixed integrated designs, and the type and number of sensors cannot be flexibly adjusted. When it is necessary to add new types of gases to be detected in the production environment (such as expanding from detecting methane to detecting methane and hydrogen sulfide at the same time), the entire sensing device must be replaced or the monitoring system must be re-laid, which not only increases the cost of equipment investment, but also leads to production interruption.

[0004] Furthermore, existing gas early warning sensor structures mostly only have a single alarm function. When a gas concentration exceeds the standard, they can only alert personnel through audible and visual signals, failing to directly trigger emergency response actions. After receiving the warning, personnel must manually close relevant pipeline valves, during which time the gas leak may continue to expand, causing the danger zone to spread. In view of this, we propose a multi-level early warning sensor installation structure for gas production environments. Utility Model Content

[0005] The purpose of this invention is to provide a multi-level early warning sensor installation structure for gas production environments, so as to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-level early warning sensor installation structure for gas production environments includes an explosion-proof enclosure. A control host is housed inside the explosion-proof enclosure. An early warning alarm is mounted on the top surface of the explosion-proof enclosure. A front cover is detachably mounted on the front side of the explosion-proof enclosure, with multiple insertion holes on the front cover. Gas detection sensors are detachably installed in the corresponding insertion holes. The remaining insertion holes are sealed by detachable sealing protrusions. A front cover is detachably mounted on the front of the front cover, and a fan is housed inside the front cover. A pipeline control valve is located on one side of the explosion-proof enclosure and is installed on the pipeline of the gas production equipment. The control host is used to control the opening and closing of the pipeline control valve.

[0008] Preferably, the inner wall of the explosion-proof shell is provided with an anti-corrosion lining, the thickness of which is between 0.5mm and 1.2mm;

[0009] This feature enables internal corrosion protection.

[0010] Preferably, the side panel of the explosion-proof housing is provided with wiring holes for wiring operations, and the wiring holes are sealed to the cables with sealant.

[0011] This setting facilitates wiring operations.

[0012] Preferably, a plurality of heat sinks are fixedly installed on the top plate of the explosion-proof housing, and the two ends of the heat sinks are respectively located on the inner and outer sides of the housing of the explosion-proof housing;

[0013] This setting can further improve heat dissipation.

[0014] Preferably, both the end of the housing of the gas detection sensor and the end of the sealing protrusion are fixedly mounted with a fixing bracket, and the fixing bracket is detachably mounted on the rear side of the front cover plate by a plurality of fastening screws.

[0015] This feature facilitates the installation and removal of the gas detection sensor and the sealing protrusion.

[0016] Preferably, a fixing frame is fixedly installed on the rear housing of the front cover, and the fixing frame is detachably installed on the front side of the front cover by a plurality of fastening screws.

[0017] Preferably, air vents are provided on both the left and right side panels of the front cover, and a vertical sleeve for support is provided at the bottom of the explosion-proof shell.

[0018] The air outlet in this design facilitates normal airflow, and the vertical sleeve provides support during operation.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model, by setting multiple insertion holes on the front cover plate, and gas detection sensors and sealing protrusions that can be detachably installed in the insertion holes, combined with the detachable connection design of the fixed support, allows for flexible increase or decrease of the number of gas detection sensors or replacement of different types of sensors according to the needs of the production environment without the need to replace the entire sensing device.

At the same time, the sliding fit between the vertical sleeve and the vertical plate can adjust the height of the explosion-proof shell. The explosion-proof shell can be selectively installed on the top plate or the front plate to adapt to different installation scenarios, thereby optimizing detection accuracy and improving installation flexibility.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-3 This utility model provides a technical solution: a multi-level early warning sensor installation structure for gas production environment, including an explosion-proof housing 1, a control host 11 is installed inside the explosion-proof housing 1, the explosion-proof housing 1 can provide explosion-proof protection for the internal control host 11 and other components, and provide a safe operating environment for the entire early warning sensor system;

[0034] In this embodiment, an early warning alarm 14 is installed on the top surface of the explosion-proof enclosure 1. When the control host 11 determines that the gas concentration exceeds the standard, the early warning alarm 14 can promptly issue an audible and visual warning signal to remind on-site personnel to evacuate or take action, further improving the safety of the production environment. A pipeline control valve 3 is provided on one side of the explosion-proof enclosure 1. The pipeline control valve 3 is installed on the pipeline of the gas production equipment. The control host 11 is used to control the opening and closing operation of the pipeline control valve 3. The control host 11 can receive the detection data of the gas detection sensor 16, and at the same time control the early warning alarm 14 and the pipeline control valve 3 according to the data logic to realize the automated linkage of "detection-early warning-valve control", which can quickly respond to gas leaks without manual intervention.

[0035] Specifically, a front cover plate 15 is detachably installed on the front side of the explosion-proof enclosure 1 by multiple fastening screws. The front cover plate 15 makes it easy for staff to open the explosion-proof enclosure 1 to inspect or maintain the internal control host 11 without disassembling the entire enclosure, thus reducing the difficulty of operation. A sealing ring is provided between the front cover plate 15 and the explosion-proof enclosure 1 to improve the sealing performance.

[0036] Furthermore, the front cover plate 15 is provided with multiple insertion holes 151, and a gas detection sensor 16 can be detachably installed in the corresponding insertion hole 151. The gas detection sensor 16 can detect the gas concentration in the production environment in real time and transmit the data to the control host 11, providing accurate data support for early warning and valve control. The remaining insertion holes 151 are sealed by detachable sealing protrusions 17. The sealing protrusions 17 can seal the unused insertion holes 151 to prevent external dust, moisture or flammable and explosive gases from entering the explosion-proof housing 1, ensuring that the explosion-proof performance does not fail. The insertion holes 151 provide installation positions for the gas detection sensor 16 and the sealing protrusions 17. The insertion sensor or sealing hole position can be flexibly selected according to the detection requirements to adapt to the monitoring needs of different gas production scenarios.

[0037] like Figure 3 As shown, a front cover 19 is detachably installed on the front of the front cover plate 15. A fan 193 is installed inside the front cover 19. The front cover 19 can provide physical protection for the gas detection sensor 16 to prevent the sensor from being damaged by external force, and at the same time provide installation space for the fan 193. The fan 193 can accelerate the air circulation inside the front cover 19, so that the gas can quickly contact the gas detection sensor 16, reduce detection delay, and improve the sensor's response speed to changes in gas concentration.

[0038] like Figure 3 As shown, the inner wall of the explosion-proof enclosure 1 is provided with an anti-corrosion lining 10. The thickness of the anti-corrosion lining 10 is between 0.5mm and 1.2mm. The anti-corrosion lining 10 can isolate the contact between corrosive gases or liquids in the gas production environment and the inner wall and internal components of the explosion-proof enclosure 1, thereby protecting the internal components from corrosion and extending the service life of the equipment.

[0039] like Figure 3 As shown, the explosion-proof housing 1 has wiring holes 12 on its side panel for wiring operations. The wiring holes 12 are sealed with the cables using sealant. The wiring holes 12 provide a channel for the wiring connection between the control host 11 and external components such as the gas detection sensor 16 and the pipeline control valve 3, which facilitates neat wiring and avoids messy wiring affecting maintenance. The sealant provides a sealing and protection effect.

[0040] like Figure 3 As shown, multiple heat sinks 13 are fixedly installed on the top plate of the explosion-proof housing 1. The two ends of the heat sinks 13 are located on the inner and outer sides of the housing of the explosion-proof housing 1, respectively. The heat sinks 13 can quickly transfer the heat inside the explosion-proof housing 1 to the outside through heat conduction, further improving the heat dissipation effect and ensuring that the internal components work at a suitable temperature.

[0041] like Figure 3 As shown, both the end of the housing of the gas detection sensor 16 and the end of the sealing protrusion 17 are fixedly mounted with a fixing bracket 18. The fixing bracket 18 is detachably mounted on the rear side of the front cover plate 15 by multiple fastening screws. The fixing bracket 18 provides a stable mounting base for the sensor and the sealing protrusion 17. At the same time, the detachable design facilitates quick installation and removal of both, reducing the difficulty of replacement or maintenance. In addition, a corresponding sealing ring is also provided on the front side of the fixing bracket 18, so that the fixing bracket 18 can press the sealing ring tightly on the rear side of the front cover plate 15 to ensure sealing.

[0042] like Figure 3As shown, a fixing frame 192 is fixedly installed on the rear housing of the front cover 19. The fixing frame 192 is detachably installed on the front side of the front cover 15 by multiple fastening screws. The fixing frame 192 makes the connection between the front cover 19 and the front cover 15 more stable. At the same time, the detachable design makes it easy to open the front cover 19 to inspect the fan 193 or the sensor.

[0043] like Figure 3 As shown, air outlets 191 are provided on both the left and right side panels of the front cover 19. The air outlets 191 allow the air driven by the fan 193 to flow smoothly, forming a complete airflow channel to ensure normal air circulation and ensure that the gas detection sensor 16 is in continuous contact with fresh air.

[0044] like Figure 1 and Figure 2 As shown, the bottom of the explosion-proof housing 1 is provided with a vertical sleeve 2 for support. The vertical sleeve 2 can raise the explosion-proof housing 1 to a suitable height, avoiding direct contact between the bottom of the housing and the ground water or dust. At the same time, it provides a structural basis for subsequent height adjustment and can perform stable support operations.

[0045] like Figure 1 and Figure 2 As shown, a fixed base 20 is fixedly installed at the bottom of the vertical sleeve 2. The fixed base 20 can increase the contact area between the vertical sleeve 2 and the ground, improve the placement stability of the entire device, and prevent the device from tipping over due to external force collision. A vertical plate 21 is slidably connected inside the vertical sleeve 2. The vertical plate 21 is fixed to the vertical sleeve 2 by multiple fastening bolts. A top plate 22 is fixedly installed at the top of the vertical plate 21. A front side plate 23 is fixedly installed at the front end of the top plate 22. The explosion-proof shell 1 can be detachably installed on the top surface of the top plate 22. The height of the top plate 22 can be adjusted by sliding the vertical plate 21, thereby changing the installation height of the explosion-proof shell 1. The explosion-proof shell 1 can be selectively installed on the top plate 22 or the front side plate 23. The vertical plate 21 can be pulled out separately and fixed to the corresponding position on the outside with fastening bolts, adapting to different installation scenarios such as horizontal placement and vertical wall mounting, improving installation flexibility.

[0046] It is worth noting that the control host 11 is pre-set with multiple sockets for connecting to the corresponding gas detection sensors 16. When adding the corresponding gas detection sensors 16 later, the gas detection sensors 16 can be installed by plugging and unplugging through quick-connect terminals.

[0047] It is worth noting that when the detected gas concentration is low, the yellow audible and visual alarm of the warning alarm 14 will sound; if the detected gas concentration is medium, the red audible and visual alarm of the warning alarm 14 will sound; if the detected gas concentration is high, the control host 11 will directly control the pipeline control valve 3 to close, thus realizing multi-level warning operation.

[0048] Finally, it should be noted that the pipeline control valve 3 is an electric valve. The control host 11, early warning alarm 14, pipeline control valve 3, gas detection sensor 16, corresponding connection lines, control system and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0049] When using the multi-level early warning sensor installation structure for gas production environment of this utility model, the fixed base 20 of the vertical sleeve 2 is fixed in the designated position, the vertical plate 21 is slid to adjust the height of the top plate 22 and then fixed with fastening bolts, and the explosion-proof shell 1 is installed on the top plate 22; the control host 11 is neatly connected to the gas detection sensor 16 and the pipeline control valve 3 through the wiring hole 12, the wiring hole 12 is sealed with sealant, the gas detection sensor 16 is installed in the plug hole 151 as required and fixed by the fixed support 18, the unused hole is sealed with the sealing protrusion 17, and the front cover 19 is covered.

[0050] Monitoring and early warning: When the equipment is started, the fan 193 accelerates the air circulation, which is circulated through the air outlet 191. The gas detection sensor 16 transmits the data to the control host 11. When the concentration is low, the early warning alarm 14 will sound a yellow alarm; when the concentration is medium, it will sound a red alarm; when the concentration is high, the control host 11 will directly close the pipeline control valve 3 to block the leakage.

[0051] Maintenance and repair: Turn off the equipment, remove the front cover 19 to repair the fan 193 or the sensor; open the front cover 15 to repair the control host 11. When installing a sensor, connect it to the quick-connect terminal block through the control host 11 socket.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
