[0031] It should be noted that a retaining wall with an open upper end is fixedly connected to the support platform, and a sealing cover is arranged on the retaining wall; a closed space is formed by the combination of the support platform, the retaining wall, and the sealing cover. The sealing space can be quickly opened or closed by disassembling or installing the sealing cover, which is fast and convenient. After opening, it is convenient for the rapid diffusion of smoke and high temperature, etc.; a fire detector is arranged on the inner wall of the sealing cover. The separate arrangement of the retaining wall and the sealing cover facilitates the installation and disassembly of the fire detector; during testing, the fire detector is installed first and then the sealing cover is covered on the retaining wall; after the test is completed, the sealing cover is removed and then the fire detector is disassembled. There is no need to disassemble and install the fire detector in a closed space. At the same time, the plug-in structure is used to replace connection methods such as screws to install the fire detector, which can greatly improve the installation efficiency; the splicing method of the sealing cover 3 and the retaining wall 2 can facilitate the opening and disassembly of the closed space, facilitate the rapid diffusion of smoke or high temperature, so that the inside of the retaining wall 2 quickly returns to the initial state; and the fire detector 14 is arranged in the sealing cover 3 and fixed by the plug-in structure, which is convenient for the installation and disassembly of the fire detector 14.
[0032] In this embodiment, the plug-in structure includes a spring groove 20 opened in the sealing cover 3. One end of the plug rod 22 passes through the spring groove 20 and is inserted into the jack 18. A limiting plate 19 is arranged at one end of the plug rod 22 inside the spring groove 20, and a handle is arranged at one end of the plug rod 22 outside the sealing cover 3.
[0033] In this embodiment, a compression spring 21 sleeved on the plug rod 22 is arranged in the spring groove 20, and the compression spring 21 has a reserved compression amount, which can continuously generate pressure on the limiting plate 19, thereby increasing the stability of the plug rod 22.

[0036] In this embodiment, a fan 17 is arranged on the inner wall of the retaining wall 2, which can accelerate the diffusion of smoke or high temperature inside the retaining wall 2.
[0037] When the utility model is in use, such as Figure 3 , 5As shown, before testing the fire detector 14, the sealing cover 3 and the enclosure 2 are in a separated state; first, install the fire detector 14, pull the insertion rod 22, so that the insertion rod 22 slides a certain distance in the spring groove 20, and at the same time, the limit plate 19 compresses the compression spring 21. Install the installation block 13 into the groove 12, release the insertion rod 22, and under the action of the resilience of the compression spring 21, the insertion rod 22 slides and inserts into the insertion hole 18; if when the installation block 13 is installed into the groove 12, the insertion hole 18 is not aligned with the insertion rod 22, then after releasing the insertion rod 22, rotate the fire detector 14, and when the insertion hole 18 is aligned with the insertion rod 22, the insertion rod 22 can still be inserted into the insertion hole 18.
[0038] As Figure 1 , 2 , as shown in Figure 4, after installing the fire detector 14, cover the entire sealing cover 3 on the enclosure 2; the sealing block 11 is inserted into the sealing groove 8, which can increase the sealing performance between the sealing cover 3 and the enclosure 2; first, start the smoke generator 7, and send smoke into the enclosure 2 through the connection hole 10. The smoke sensor 15 can record the smoke concentration in the enclosure 2 and transmit the value to the controller 5, which is displayed on the display screen 4; when the fire detector 14 issues an alarm, the controller 5 records the smoke concentration at this time and presents the value on the display screen 4. At this time, the smoke detection performance test of the fire detector 14 is completed.
[0039] Then open the sealing cover 3, start the fan 17 to quickly disperse the smoke in the enclosure 2, and then start the heater 9 after closing the sealing cover 3 to raise the temperature in the enclosure 2; the temperature sensor 16 can record the temperature in the enclosure 2 and transmit the value to the controller 5, which is displayed on the display screen 4; when the fire detector 14 issues an alarm, the controller 5 records the temperature at this time and presents the value on the display screen 4. At this time, the temperature detection performance test of the fire detector 14 is completed.
[0040] Then open the sealing cover 3, start the fan 17 to quickly lower the temperature in the enclosure 2 to normal temperature, and then start the smoke generator 7 and the heater 9 after closing the sealing cover 3 so that there is both temperature rise and smoke in the enclosure 2; the smoke sensor 15 can record the smoke concentration in the enclosure 2, and the temperature sensor 16 can record the temperature in the enclosure 2 and transmit the values to the controller 5, which are displayed on the display screen 4; when the fire detector 14 issues an alarm, the controller 5 records the temperature and smoke concentration at this time and presents the values on the display screen 4, and observe the response of the fire detector 14 when there is both smoke and temperature, and comprehensively test the performance of the fire detector 14.
[0041] After the test is completed, open the sealing cover 3 and then start the fan 17 again to accelerate the heat dissipation and smoke dissipation of the enclosure 2. At the same time, pull the insertion rod 22 so that the insertion rod 22 disengages from the insertion hole 18. At this time, the fire detector 14 can be quickly and conveniently taken out of the sealing cover 3; reinstall the next fire detector 14 for testing, and repeat this process in a cycle.
