Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Reference Figure 1 、 Figure 2 and Figure 3 , the utility model provides an embodiment: a wall hole fireproof blocking device, including a blocking cover 1, a sealing cover 3 is fixedly connected to the front side of the inner wall of the blocking cover 1, a sealing plate 23 is rotatably connected to the inner side of the sealing cover 3, a wax block 4 is fixedly connected to the right side of the inner wall of the sealing cover 3, a counterweight 5 is fixedly connected to the right side of the outer wall of the sealing plate 23, a spring rod 6 is fixedly connected to the bottom of the inner wall of the wax block 4, an insertion rod 7 is slidably connected to the front side of the inner wall of the wax block 4, a slot 8 is provided on the outside of the counterweight 5, the insertion rod 7 is engaged with the slot 8, a mounting plate 9 is fixedly connected to the rear side of the inner wall of the blocking cover 1, a DC motor 10 is fixedly connected to the rear side of the mounting plate 9, the output end of the DC motor 10 passes through the mounting plate 9 and is fixedly connected to the fan blade 11, and a positioning mechanism 2 is provided on the outside of the blocking cover 1;

[0039] Specifically, starting the DC motor 10 can drive the fan blades 11 to rotate for ventilation. In the event of a fire, the high temperature melts the wax block 4, and the counterweight block 5 causes the sealing plate 23 to rotate along the sealing cover 3, pushing the spring rod 6 to compress, and the insert rod 7 is inserted into the slot 8 for sealing. The rotation of the fan blades 11 can still dissipate heat from the sealing cover 3 and the sealing plate 23, maintaining ventilation, and automatically sealing the holes in the event of a fire to improve heat resistance.

[0040] Reference Figure 1 and Figure 3 The positioning mechanism 2 includes two positioning covers 201, which are respectively fixedly connected to the left and right sides of the outer wall of the blocking cover 1. The inner side of the positioning cover 201 is rotatably connected to a worm 202. The upper and lower sides of the outer wall of the worm 202 are fixedly connected to threaded columns 203. The outer side of the threaded column 203 is threadedly connected to a plug-in block 204. The left and right sides of the outer wall of the blocking cover 1 are fixedly connected to a motor 205. The output end of the motor 205 is fixedly connected to a turbine 206, which is meshed with the worm 202.

[0041] Specifically, starting the motor 205 can rotate the turbine 206, and the turbine 206 drives the worm 202 and the threaded column 203 to rotate together through the meshing transmission belt. The threaded column 203 is connected to the plug-in block 204 through a threaded connection, thereby realizing rapid disassembly and assembly of the device.

[0042] Reference Figure 2 and Figure 3, a filter screen 17 is fixedly connected to the middle of the inner wall of the blocking cover 1, and the bottom of the blocking cover 1 is connected to the ash discharge port 18; the left and right sides of the front end of the blocking cover 1 are fixedly connected to handles 12, and the outer sides of the two handles 12 are fixedly connected to the sheath 13; the upper and lower sides of the outer walls of the two positioning covers 201 are fixedly connected to positioning blocks 21, and the outer sides of the multiple positioning blocks 21 are provided with positioning holes 22;

[0043] Specifically, impurities in the air flow can be intercepted by the filter 17, and then the impurities will be discharged through the ash discharge port 18. The handle 12 and the sheath 13 thereon can facilitate the movement and transportation of the device. The positioning block 21 can be installed and fixed by installing a screw part in the positioning hole 22 thereon.

[0044] Reference Figure 1 、 Figure 2 and Figure 3 The upper and lower sides of the outer wall of the blocking cover 1 are fixedly connected to brackets 19, and the outer sides of the two brackets 19 are fixedly connected to the connecting plates 20; the front top of the blocking cover 1 is fixedly connected to the controller 14, and the controller 14 is electrically connected to the DC motor 10 and the motor 205 respectively; the outer side of the controller 14 is fixedly connected to the housing 15, and the outer side of the housing 15 is rotatably connected to the shield 16;

[0045] Specifically, the bracket 19 and the connecting plate 20 thereon can improve the structural strength of the sealing cover 1 to prevent it from being deformed due to high temperature during a fire. The controller 14 can control the starting and operating power between the DC motor 10 and the motor 205 respectively. The outer shell 15 can improve the protection capability of the controller 14. The opening and closing of the protective cover 16 can prevent the controller 14 from being accidentally touched when not in use.

[0046] Working principle: Before using the device, first start the DC motor 10 to drive the fan blades 11 to rotate for ventilation. When a fire occurs, the high temperature of the fire will melt the wax block 4. At this time, the weight of the counterweight 5 will drive the sealing plate 23 to rotate along the sealing cover 3, and the thrust of the sealing plate 23 during rotation will compress the spring rod 6, so that the plug rod 7 on its top will fall and be inserted into the slot 8 to complete the sealing. At this time, the rotation of the fan blades 11 can still dissipate heat for the sealing cover 3 and the sealing plate 23, and can automatically seal the holes in the event of a fire without affecting ventilation. At the same time, it can dissipate heat to improve its heat resistance, thereby improving the reliability of the device. By starting the motor 205 to drive the turbine 206 to rotate, the worm 202 and the threaded column 203 thereon can be driven to rotate through meshing transmission, so as to drive the plug-in block 204 to move up and down through a threaded connection, and the device can be quickly disassembled and assembled by moving the plug-in block 204, thereby improving the convenience of the device.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
