[0001] The invention relates to the technical field of ship fire detection, and in particular to a ship-based touch-screen combustible gas detection alarm control box. Background Art

[0002] When a ship is sailing, the leakage of flammable gas may cause serious fire and explosion accidents, posing a huge threat to the safety of life and property of ship personnel. Therefore, it is particularly important to detect flammable gas in a timely and accurate manner and send out alarm signals. The existing flammable gas detection alarm controller uses LED indicator lights to display flammable gas detector fault alarms, and cannot monitor the flammable gas concentration in real time. Once there are too many detection areas, the flammable gas detection alarm controller is large and ugly, which is not convenient for operators to monitor intuitively, and greatly hinders operators from analyzing the on-site situation.

[0003] To this end, we provide a marine touch-screen combustible gas detection alarm control box to solve the above problems. Summary of the invention

[0050] Work Application:

[0051] See also Figure 2 , a 7-inch touch screen is used in the center of the appearance panel, and there are main power indication, backup power indication, dimmer, mute button, reset button and buzzer below the touch screen. When connected to the AC 220V power supply, the main power indicator light is on, and when connected to the DC 24V power supply, the backup power indicator light is on. The dimmer is used to adjust the brightness of the main power indicator and the backup power indicator.

[0052] See also Figure 3 , the touch screen of the marine touch-screen combustible gas detection alarm control box displays 4 interface contents. The first homepage interface content shows that the touch screen of the marine touch-screen combustible gas detection alarm control box receives 6 marine touch-screen combustible gas detection alarms to form a combustible gas detection alarm system. When the marine touch-screen combustible gas detection alarm works normally, a colorless circle is displayed below the corresponding area of ​​the touch screen. If the marine touch-screen combustible gas detection alarm has a first-level or second-level alarm, the colorless circle will turn red and flash. At the same time, the second concentration interface will display the concentration value of the alarm marine touch-screen combustible gas detection alarm, and display the first-level alarm mark or the second-level alarm mark of the marine touch-screen combustible gas detection alarm. The alarm interface records the alarm situation of the marine touch-screen combustible gas detection alarm in this area; if the marine touch-screen combustible gas detection alarm fails, the colorless circle will turn yellow and flash, and the fault interface records the fault situation of the marine touch-screen combustible gas detection alarm in this area.

[0053] Please refer to the instruction manual Figure 1-8 The present invention also provides a technical solution: a marine touch-screen combustible gas detection alarm, which is used in conjunction with a marine touch-screen combustible gas detection alarm control box. The marine touch-screen combustible gas detection alarm is installed at different locations on the ship, such as: 6 marine touch-screen combustible gas detection alarms are respectively arranged in the supply equipment warehouse, paint room, boiler room, cargo oil pump room, main engine room and auxiliary engine room; when the marine touch-screen combustible gas detection alarm detects that the combustible gas concentration at the corresponding location exceeds the standard, the information is fed back to the CPU unit in the marine touch-screen combustible gas detection alarm control box, and the CPU unit collects the first-level alarm and the second-level alarm of the combustible gas detector to output signals to the output unit buzzer, and the sound and light alarm reminds the on-site operator to handle it.

[0054] See also Figure 7 and Figure 8 , discloses the specific structure of a marine touch-screen combustible gas detection alarm, including: a support frame structure and a detector body 11. The height of the detector body 11 is adjustable, so that the detector body 11 can be installed at a suitable height position.

[0055] For example, when the detector body 11 is used on a ship, the installation height needs to be controlled within the range of 0.1-2 meters. Within this height range, the concentration of combustible gas in the air can be effectively detected and an alarm can be issued in time. However, the installation height also specifically considers the following factors:

[0056] First: gas specific gravity. If the combustible gas detected is heavier than air, the detector body 11 should be installed at a higher position, usually within the range of 1.5-1.8 meters. If the gas is lighter than air, it should be installed at a lower position, about 15-30 cm in height.

[0057] Second: the height of the release source. According to the height and characteristics of the gas release source, the installation position of the detector body 11 should be appropriately adjusted. If the release source height is high, the detector body 11 should be installed at a lower position, and vice versa.

[0058] Third: Installation environment: Avoid installing the detector body 11 in a poorly ventilated or dead corner to ensure the accuracy and sensitivity of its detection.

[0059] Therefore, in the present invention, based on the ability to adjust the height of the detector body 11, it is convenient to adjust the appropriate height position according to different types of detector bodies 11 actually used and different installation conditions, and the practicality is strong.

[0060] Furthermore, the support frame structure in the present invention not only provides a stable support structure of triangular support, but also can realize three-level adjustment of the height of the detector body 11 , and can accurately adjust the height position of the detector body 11 .

[0061] Specifically, the support frame structure includes a magnetic suction cup 1, an arc-shaped bracket 2, a connecting plate 4, a connecting block 5, a threaded sleeve 6, a threaded adjustment rod 7 and a mounting shell 8. The bottom of the mounting shell 8 is fixedly connected to the top of the threaded adjustment rod 7. The mounting shell 8 is a cylindrical structure with an upper end opening. The detector body 11 is telescopically engaged in the mounting shell 8. A rain cap 9 is installed above the detector body 11. The rain cap 9 is a conventional rain cover structure. The detection head 10 on the detector body 11 is located inside the rain cap 9. The combustible gas enters and exits the rain cap 9 and is thus detected by the detection head 10. The rain cap 9 not only prevents rain and water, but also prevents collision, reducing the problem of damage to the detection head 10. The mounting shell 8 serves the purpose of protecting the detector body 11.

[0062] A slide groove 12 is symmetrically arranged at the outer ring of the mounting shell 8, a threaded hole 13 is arranged in the middle of the slide groove 12, and an adjusting screw 14 is symmetrically arranged at the outer ring of the mounting shell 8. A rectangular frame handrail 15 is fixedly installed on the adjusting screw 14. The end of the adjusting screw 14 close to the slide groove 12 has a magnetic end, and the magnetic end is attracted and fixed to the outer shell of the detector body 11. At the same time, the magnetic end is also attracted and fixed to the slide groove 12. When the detector body 11 is not installed in the mounting shell 8, the end of the adjusting screw 14 is connected to the threaded hole 13 through threaded cooperation to avoid loss. When operating, the rectangular frame handrail 15 is used to rotate the adjusting screw 14, which is easy to operate.

[0063] When the detector body 11 is installed in the mounting shell 8, the end of the adjusting screw 14 is moved out of the threaded hole 13, and the adjusting screw 14 is adsorbed and fixed in the slide groove 12, and the adjusting screw 14 can also slide in the slide groove 12. The adjusting screw 14 is fixed as it slides. When the adjusting screw 14 slides along the height direction of the mounting shell 8, the detector body 11 is attracted by the magnetic end of the adjusting screw 14 and also slides along the height direction of the mounting shell 8, thereby finely adjusting the height of the detector body 11.

[0064] It should be noted that the outer shell of the detector body 11 is a stainless steel outer shell, and the specific shape of the outer shell of the detector body 11 is set according to the model or type of the detector body 11 actually used, which is not limited here.

[0065] Furthermore, the present invention can also adjust the height of the detector body 11 over a wide range. Specifically, the threaded sleeve 6 is connected to the outer ring of the threaded adjustment rod 7 through threaded cooperation. When the threaded adjustment rod 7 is rotated, the height of the detector body 11 can be adjusted over a wide range. The specific adjustment height range can be determined according to the actual height of the threaded adjustment rod 7.

[0066] In the present invention, three connecting blocks 5 are fixed at equal angles on the outer circle of the threaded sleeve 6, six connecting plates 4 are provided, six groups of screw and nut assemblies 3 are provided, three arc-shaped brackets 2 and three magnetic suction cups 1 are provided, and the magnetic suction cup 1 is fixedly installed at the bottom of the arc-shaped bracket 2, and is adsorbed and fixed between the magnetic suction cup 1 and supports on the hull such as decks, containers, etc. The magnetic suction cup 1 also has magnetism, which is convenient for adsorption and fixation on some supports that can be magnetically adsorbed, thereby increasing the stability of the fixation.

[0067] The upper end of the arc bracket 2 corresponds to the end of the connecting block 5 away from the threaded sleeve 6, and each group of arc brackets 2 and connecting blocks 5 are connected by a pair of screw-nut assemblies 3 and a pair of connecting plates 4, wherein a pair of connecting plates 4 are symmetrically arranged on both sides of the arc bracket 2 and the connecting block 5, and a pair of screw-nut assemblies 3 are arranged at both ends of the connecting plate 4. The screw-nut assembly 3 includes a screw and a nut. The screw passes through a pair of connecting plates 4 and the arc bracket 2 or the connecting block 5 at the same time. The nut is connected to the end of the screw by threaded cooperation. When the nuts at both ends of the screw are tightened, the relative position of the arc bracket 2 and the connecting block 5 can be locked and fixed; when it is necessary to increase the adjustment range of the height of the detector body 11, the nut is screwed into a loose state so that the overall height of the threaded sleeve 6, the threaded adjustment rod 7, the mounting shell 8 and the detector body 11 can be adjusted, and then the nut is tightened so that the relative position of the arc bracket 2 and the connecting block 5 is locked and fixed to complete the positioning.

[0068] Furthermore, when the height adjustment range of the detector body 11 is increased, the degree of opening and closing between the three arc-shaped brackets 2 can also be changed, thereby adjusting the support stability, which is convenient for increasing the stability of the detector body 11 by increasing the degree of opening and closing between the three arc-shaped brackets 2 under strong winds and waves or special conditions, and reducing the opening and closing angles between the three arc-shaped brackets 2 in conventional usage scenarios to reduce space occupancy. It is particularly suitable for use with a marine touch-screen combustible gas detection alarm control box, meeting the requirements of a small overall size and convenient monitoring for the marine touch-screen combustible gas detection alarm.

[0069] In addition, this specification only clearly describes one implementation scheme, and those skilled in the art can configure other implementation schemes and configure multiple independent schemes.
