Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Referring Figures 1-3 , the present application provides an embodiment: an open space fire safety monitoring assembly, comprising a base 1, a plurality of sliding grooves 4 are formed in the outer wall of the base 1 for accommodating limiting blocks 10 to limit the movement range of the shell 5, a detection assembly is arranged at the bottom of the base 1 for detecting indoor smoke concentration and temperature, the shell 5 is slidingly connected to the outer wall of the base 1 for protecting the internal smoke sensing component 2 and the temperature sensing component 3, a plurality of air holes 6 are formed in the bottom of the shell 5 to make the inside of the shell 5 communicate with the external environment to enable the smoke sensing component 2 and the temperature sensing component 3 to detect, a fixing assembly is arranged at the top of the shell 5 for extruding the shell 5 to fix it outside the base 1, a plurality of limiting blocks 10 are fixedly connected to the inner wall of the shell 5 to limit the movement range of the shell 5;

[0034] The fixing assembly comprises an extrusion strip 7, a plurality of limiting strips 8 and a spring one 9, the outer wall of the extrusion strip 7 is slidingly connected inside the shell 5, cooperates with the spring one 9 to provide support force for the shell 5, so that the limiting block 10 is fixed at the deepest part of the sliding groove 4, each limiting strip 8 is fixedly connected to the bottom of the extrusion strip 7 on one side to limit the movement range of the extrusion strip 7, the spring one 9 is arranged inside the shell 5 to provide elastic force for the extrusion strip 7 to support the shell 5, one end of the spring one 9 is fixedly connected inside the shell 5, the other end of the spring one 9 is fixedly connected to the bottom of the extrusion strip 7, the detection assembly comprises the smoke sensing component 2 and the temperature sensing component 3, the top end of the smoke sensing component 2 is fixedly connected to the bottom of the base 1 for detecting smoke concentration in the external environment, the top end of the temperature sensing component 3 is fixedly connected to the bottom of the base 1 for detecting temperature in the external environment, the smoke sensing component 2 and the temperature sensing component 3 are arranged in a symmetrical array at the bottom of the base 1.

[0035] Specifically, when the shell 5 needs to be opened to maintain the internal smoke sensing component 2 and the temperature sensing component 3, the maintainer needs to hold the shell 5 and then slowly push it upwards. In this process, the extrusion strip 7 inside the shell 5 is subjected to a downward force and gradually retracts into the shell 5. At the same time, the limiting block 10 on the inner wall of the shell 5 also slowly comes out of the deepest part of the sliding groove 4 under this pushing action. Then, the maintainer rotates the shell 5 counterclockwise to make the limiting block 10 further slide out along the track of the sliding groove 4. After that, the maintainer releases the tightly held shell 5. At this time, the spring I 9 installed inside pushes the shell 5 to move downward by its elastic potential energy, so that the limiting block 10 completely comes out of the deep part of the sliding groove 4. Thus, the disassembly of the shell 5 is successfully completed.

[0036] Referring to Figure 4 and Figure 5 , the base 1 is slidably connected with a connecting seat 11 at the top for connecting equipment. The base 1 is slidably connected with a plurality of limiting plates 12 inside for limiting the movement of the equipment. Each limiting plate 12 is fixedly connected with a handle 13 on the outer wall for pulling the limiting plate 12 to move and in turn drive the fixed pin 14 and the sliding bar 15. Each limiting plate 12 is fixedly connected with the fixed pin 14 on the inner wall for fixing the base 1 at the bottom of the connecting seat 11. Each limiting plate 12 is fixedly connected with the sliding bar 15 on the inner wall for providing mechanical support for the movement of the limiting plate 12 and guiding the movement direction. Each sliding bar 15 is fixedly connected with a sliding column 16 on both sides for limiting the movement range of the sliding bar 15. Each sliding column 16 is provided with a spring II 17 on one side for providing elastic force to the limiting plate 12 so that it can rebound into the base 1. One end of each spring II 17 is fixedly connected inside the sliding column 16. The other end of each spring II 17 is fixedly connected inside the base 1. Each fixed pin 14 is slidably connected inside the connecting seat 11 on the outer wall.

The sliding columns 16 are arranged in symmetrical array between the sliding bars 15 on both sides. Each sliding column 16 is slidably connected inside the base 1 on the outer wall.

[0037] Specifically, when the device is replaced or overhauled, the worker needs to first stretch out both hands to hold the handle 13, and then evenly pull it outwards, in this process, the fixed pin 14 connected with the handle 13, originally embedded in the connecting seat 11, slowly comes out of the connecting seat 11 with the outward pulling action of the handle 13, when the fixed pin 14 completely comes out of the connecting seat 11, the connection of the device with the roof is released, the worker dismounts the device from the roof, and then the overhauling work can be carried out, after the overhauling work is successfully completed, the device installation link is entered again, the worker holds the handle 13 again and pulls it outwards, so that the space originally with certain resistance at the top of the base 1 is opened, then the worker aligns and fits the base 1 with the bottom end of the connecting seat 11, after fitting in place, the tightly held handle 13 is released, at this time, the spring two 17 in the device begins to play a role, driven by the elastic potential energy, the handle 13 quickly shrinks inwards, and the fixed pin 14 linked therewith also quickly follows, and re-enters the connecting seat 11, thus, the replacement or overhauling of the device is successfully completed, and the whole device is again stably installed on the roof, and returns to the normal running state.

[0038] Working principle: in the process of using the open space fire safety monitoring assembly, when the device needs to be replaced or overhauled, first hold the handle 13 and pull it outwards, so that the fixed pin 14 comes out of the connecting seat 11, and then the device is dismounted from the roof for overhauling, then the shell 5 needs to be opened to overhaul the internal smoke sensing component 2 and temperature sensing component 3, first hold the shell 5 and push it upwards, so that the extrusion strip 7 is retracted into the shell 5, and at the same time the limiting block 10 comes out of the deepest part of the sliding groove 4, then rotate the shell 5 counterclockwise, so that the limiting block 10 slides out of the deep part of the sliding groove 4, then release the shell 5, which will move outward under the action of the spring one 9, so that the limiting block 10 completely comes out of the deep part of the sliding groove 4, thereby completing the dismounting of the shell 5, then the internal smoke sensing component 2 and temperature sensing component 3 are inspected, when the overhauling is completed, hold the handle 13 again and pull it outwards to open the space at the top of the base 1, then fit it with the bottom end of the connecting seat 11, and at the same time release the handle 13, so that it shrinks inwards under the action of the spring two 17, so that the fixed pin 14 re-enters the connecting seat 11, thereby completing the replacement or overhauling of the device.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application.
