Description

Technical Field

[0001] This utility model relates to the field of civil defense engineering technology, specifically to a fire monitoring device for civil defense engineering that is easy to install. Background Technology

[0002] Civil air defense projects refer to underground structures built in conjunction with ground buildings that can be used for air defense during wartime. Their safety is of paramount importance. In the event of a fire, due to their relatively enclosed space, dense population, and storage of materials, the fire can spread rapidly, making evacuation and rescue difficult and easily causing significant casualties and property damage. Therefore, reliable and efficient fire monitoring equipment is a key component of the safety guarantee system of civil air defense projects. However, existing fire monitoring equipment still has certain shortcomings in its use.

[0003] A fire alarm monitoring device, as proposed in application number CN202421039420.6, includes a main body and a protective mechanism. The main body includes a mounting shell, a heat flame detector, and a smoke flame detector. The heat flame detector is installed on one side of the mounting shell, and the smoke flame detector is installed on the inside side of the mounting shell. A mounting groove is integrally formed on one side of the mounting shell, and an alarm is installed on the inside side of the mounting shell. The protective mechanism includes a protective shell, which is threadedly connected to the mounting shell via the mounting groove. Dustproof nets are evenly distributed on one side of the protective shell. In actual use, this fire alarm monitoring device is fixedly installed using a mounting bracket and bolts. This makes disassembly, repair, and replacement inconvenient when the device is damaged. Furthermore, the threaded connection between the protective shell and the mounting shell via the mounting groove is prone to aging and jamming during prolonged use, hindering convenient cleaning and repair of internal components and further reducing the ease of disassembly and maintenance.

[0004] Therefore, we propose a fire monitoring device for civil defense projects that is easy to install, in order to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a fire monitoring device for civil defense projects that is easy to install, so as to solve the problem of reduced ease of disassembly, assembly and maintenance mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire monitoring device for civil defense projects that is easy to install, comprising a monitoring and alarm component and a mounting plate;

[0007] The top of the monitoring and alarm component is fixedly connected to a fixing plate, the bottom of the fixing plate is movably connected to a connecting shell, and the bottom of the connecting shell is fixedly installed with a protective bottom shell.

[0008] A connection positioning mechanism is provided between the connecting shell and the fixing plate to enable quick assembly and disassembly of the two.

[0009] A rotating connection mechanism is installed between the mounting plate and the fixed plate to improve the ease of disassembly and maintenance.

[0010] Preferably, the connection positioning mechanism includes snap-fit ​​seats symmetrically installed on the top of the connection shell, and positioning rods symmetrically installed inside the protective bottom shell.

[0011] Preferably, the connecting positioning mechanism further includes positioning sleeves symmetrically installed on the bottom surface of the fixed plate. A limiting plate is symmetrically installed on the bottom surface of the fixed plate. A movable rod slides symmetrically through the inside of the limiting plate. A connecting plate is fixedly installed on the outer end of the movable rod. A return spring is sleeved on the outer ring of the movable rod between the connecting plate and the limiting plate. A snap-fit ​​block is fixedly installed on the outer side of the connecting plate.

[0012] Preferably, the positioning rod is movably connected to the positioning sleeve, the connecting plate and the snap-fit ​​block form a telescopic structure with the connecting plate through a return spring, and the snap-fit ​​block is movably engaged with the snap-fit ​​seat.

[0013] The above-described structure design allows the positioning mechanism to achieve rapid assembly and disassembly of the protective bottom shell through the coordinated action of components such as the positioning rod, positioning sleeve, snap-fit ​​seat, and snap-fit ​​block. The insertion of the positioning rod into the positioning sleeve, combined with the snap-fit ​​block engaging with the snap-fit ​​seat under the action of the return spring, allows for quick connection without tools. Furthermore, pressing the snap-fit ​​block inward to disengage it from the snap-fit ​​seat facilitates disassembly, making it convenient for inspection and cleaning of internal components and improving the ease of disassembly and maintenance.

[0014] Preferably, the rotating connection mechanism includes a connecting block fixedly installed on the top surface of the fixed plate, and four sets of buckles are installed at equal angles on the outer ring of the connecting block. A rotating plate is rotatably installed on the top of the connecting block.

[0015] Preferably, the rotary connection mechanism further includes a sleeve fixedly installed on the bottom surface of the mounting plate. The bottom end of the sleeve is provided with slots at equal angles, and there are four sets of slots. The sleeve is provided with a telescopic spring inside. The top end of the telescopic spring is fixedly connected to the bottom surface of the mounting plate, and the bottom end of the telescopic spring is fixedly installed with a bonding plate.

[0016] Preferably, the bonding plate is telescopically connected to the mounting plate via a telescopic spring, and the connecting block is movably engaged with the slot via a buckle. The bonding plate can press the rotating plate and the connecting block to secure the engagement between the buckle and the slot.

[0017] The above-described structural design utilizes a rotating connection mechanism consisting of a connecting block, buckle, sleeve, slot, telescopic spring, and bonding plate to ensure stable installation and easy maintenance of the equipment. Initial installation is achieved by the buckle engaging with the slot. Under the action of the telescopic spring, the bonding plate presses against the rotating plate and connecting block, securing the buckle and slot and ensuring that the equipment does not loosen in complex environments. Pressing the fixing plate causes the bonding plate to compress the spring, and rotating the fixing plate and connecting block causes the buckle to rotate out of the slot. This facilitates the rapid assembly and disassembly of the fire monitoring equipment, significantly improving the ease of maintenance and disassembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are: it provides a fire monitoring device for civil defense projects that is easy to install;

[0019] 1. In terms of ease of installation and disassembly, the connecting positioning mechanism plays a key role. The insertion and cooperation of the positioning rod and the positioning sleeve, combined with the automatic engagement of the locking block with the locking seat under the action of the return spring, allows for the rapid assembly of the monitoring alarm component and the protective base without the need for professional tools. During disassembly, simply squeezing the locking block to disengage it from the locking seat is sufficient to easily separate the components, greatly shortening the operation time for installation and maintenance and significantly improving work efficiency.

[0020] 2. In terms of equipment stability and ease of maintenance, the rotating connection mechanism is highly effective. The engagement of the buckle and the slot completes the initial installation. Under the action of the telescopic spring, the bonding plate applies pressure to the rotating plate and the connecting block, further tightening the connection between the buckle and the slot. This effectively resists the influence of the complex environment of civil defense projects, ensuring that the equipment is stable and does not loosen. When maintenance is required, pressing the fixing plate can compress the spring, and rotating the fixing plate can quickly disassemble the monitoring and alarm components, facilitating a comprehensive overhaul of the equipment. This balances stability and ease of maintenance. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a fire monitoring device for civil defense projects that is easy to install, including a monitoring and alarm component 1 and a mounting plate 13. A fixing plate 2 is fixedly connected to the top of the monitoring and alarm component 1, and a connecting shell 3 is movably connected to the bottom of the fixing plate 2. A protective bottom shell 4 is fixedly installed at the bottom of the connecting shell 3. A connection positioning mechanism is provided between the connecting shell 3 and the fixing plate 2 to achieve quick assembly and disassembly of the two. The connection positioning mechanism includes snap-fit ​​seats 5 symmetrically installed on the top of the connecting shell 3, and positioning rods 6 symmetrically installed inside the protective bottom shell 4. It also includes positioning sleeves 7 symmetrically installed on the bottom surface of the fixed plate 2, positioning rods 6 and positioning sleeves 7 being movably connected, limiting plates 8 being symmetrically installed on the bottom surface of the fixed plate 2, movable rods 9 being symmetrically slidably passing through the inside of the limiting plate 8, connecting plates 10 being fixedly installed on the outer end of the movable rods 9, a return spring 11 being sleeved on the outer ring of the movable rods 9 between the connecting plate 10 and the limiting plate 8, and a snap-fit ​​block 12 being fixedly installed on the outer side of the connecting plate 10. The connecting plate 10 and the snap-fit ​​block 12 form a telescopic structure with the connecting plate 10 through the return spring 11, and the snap-fit ​​block 12 is movably snap-fitted into the snap-fit ​​seat 5.

[0030] In the design of the above structure, when installing the monitoring alarm component 1 and the protective base 4, the positioning rod 6 on the protective base 4 is aligned with the positioning sleeve 7 on the bottom surface of the fixing plate 2 and inserted. As the positioning rod 6 gradually penetrates into the positioning sleeve 7, the connecting shell 3 moves upward synchronously, and the locking seat 5 also approaches the locking block 12 on the bottom surface of the fixing plate 2. Since the locking block 12 is connected to the connecting plate 10, and the movable rod 9 passes through the limiting plate 8 and is fitted with a return spring 11 on the outer ring, when the locking seat 5 contacts the locking block 12, it will... The snap-fit ​​block 12 is squeezed, forcing the snap-fit ​​block 12 to drive the connecting plate 10 and the movable rod 9 to overcome the elastic force of the return spring 11 and slide inward. When the snap-fit ​​seat 5 moves to the appropriate position, the snap-fit ​​block 12 is no longer squeezed by the snap-fit ​​seat 5. At this time, the return spring 11 releases its elastic force, pushing the connecting plate 10 and the snap-fit ​​block 12 to return outward, so that the snap-fit ​​block 12 is accurately snapped into the snap-fit ​​seat 5, thereby realizing the stable connection between the connecting shell 3 and the fixing plate 2, and completing the rapid installation of the protective bottom shell 4.

[0031] During disassembly, the operator only needs to press the snap-fit ​​block 12 inward. Then, the snap-fit ​​block 12 drives the connecting plate 10 and the movable rod 9 to slide inward against the elastic force of the return spring 11, thereby causing the snap-fit ​​block 12 to disengage from the snap-fit ​​seat 5. After the snap-fit ​​block 12 is completely disengaged from the snap-fit ​​seat 5, the connecting shell 3 can be easily separated from the fixing plate 2, which facilitates maintenance operations such as inspection and cleaning of the internal components.

[0032] A rotating connection mechanism is provided between the mounting plate 13 and the fixed plate 2 to improve the convenience of disassembly and maintenance. The rotating connection mechanism includes a connecting block 14 fixedly installed on the top surface of the fixed plate 2. The outer ring of the connecting block 14 is equipped with four sets of buckles 15 at equal angles. A rotating plate 16 is rotatably installed on the top of the connecting block 14. The rotating connection mechanism also includes a sleeve 17 fixedly installed on the bottom surface of the mounting plate 13. The bottom end of the sleeve 17 is provided with four sets of slots 18 at equal angles. A telescopic spring 19 is provided inside the sleeve 17. The top end of the telescopic spring 19 is fixedly connected to the bottom surface of the mounting plate 13. A bonding plate 20 is fixedly installed on the bottom end of the telescopic spring 19. The bonding plate 20 is telescopically connected to the mounting plate 13 through the telescopic spring 19. The connecting block 14 is movably engaged with the slots 18 through the buckles 15. The bonding plate 20 can press the rotating plate 16 and the connecting block 14 to secure the engagement state between the buckles 15 and the slots 18.

[0033] In the above-described structure, when installing the fire monitoring equipment, the mounting plate 13 is first installed in the required position using bolts. Then, the connecting block 14 on the top surface of the fixing plate 2 is aligned with the sleeve 17 on the bottom surface of the mounting plate 13, and the buckle 15 on the outer ring of the connecting block 14 corresponds one-to-one with the slot 18 at the bottom of the sleeve 17. Since the rotating plate 16 is rotatably mounted on the top of the connecting block 14, after the connecting block 14 is inserted into the sleeve 17, the rotating plate 16 will push the bonding plate 20 and the telescopic spring 19, thereby causing the telescopic spring 19 to retract. At this time, the connecting block 14 can be rotated appropriately so that the buckle 15 can be smoothly inserted into the slot 18. Then, under the action of the telescopic spring 19, the bonding plate 20 will exert a squeezing force on the rotating plate 16 and the connecting block 14. This squeezing force will make the buckle 15 and the slot 18 more tightly engaged, further tightening the connection between the connecting block 14 and the sleeve 17, ensuring stable installation of the equipment in the complex environment of civil defense projects.

[0034] When the equipment needs to be disassembled and maintained, push the fixing plate 2 upward, so that the fixing plate 2 moves the connecting block 14 upward inside the sleeve 17, and simultaneously moves the slot 18 upward inside the buckle 15. At this time, the telescopic spring 19 will retract. Then rotate the fixing plate 2, and the fixing plate 2 moves the connecting block 14 and the buckle 15 to rotate, so that the buckle 15 rotates along the inner wall of the slot 18 until the buckle 15 is aligned with the opening of the slot 18. Then, the telescopic spring 19 can push the bonding plate 20, and simultaneously push the connecting block 14 and the rotating plate 16 downward, and separate the buckle 15 from the slot 18. At this time, the fixing plate 2 and the monitoring and alarm components 1 connected to it can be easily removed from the mounting plate 13, which facilitates comprehensive inspection and replacement of parts and other maintenance operations of the equipment.

[0035] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
