[0029] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] like Figures 1-5 As shown, this embodiment proposes an impact-resistant non-metallic high-strength fiber fireproof prefabricated cabin, comprising:

[0032] The bottom plate 1 has a frame 2 attached to the top edge of the bottom plate 1. The top of the frame 2 is fitted with a top cover 3. The outside of the frame 2 is covered with a fireproof board 4. A hatch 5 is provided on one side of the frame 2.

[0033] Air intake window 6 is located at the top of one end of frame 2. An external air intake channel 7 is fixedly connected to the side of air intake window 6 outside frame 2. An internal air intake channel 8 is fixedly connected to the side of air intake window 6 inside frame 2. A filter screen 10 is connected to the bottom end of external air intake channel 7 and one end of internal air intake channel 8 through quick-installation assembly.

[0034] In this embodiment, the fireproof board 4 is composed of a silicate substrate and a high-strength fiber-reinforced material. The silicate substrate is made of cement and quartz sand as the main raw materials and is formed into a dense structure by high-pressure steam curing, providing basic strength and fire resistance. The high-strength fiber-reinforced material includes glass fiber, mineral fiber or high-strength composite fiber, which is uniformly dispersed in the substrate, significantly improving impact resistance and deformation resistance. This is a mature existing technology and will not be described in detail here.

[0035] In this embodiment, a mounting groove is provided at the top of the filter screen 10 located in the outer air intake channel 7. An adsorption layer 9 is fixedly connected inside the mounting groove, and the material of the adsorption layer 9 can be activated carbon. Through the setting of the adsorption layer 9, the airflow entering the outer air intake channel 7 can be filtered to prevent too many impurities from entering the cabin through the outer air intake channel 7. The pore size of the filter screen 10 located inside the outer air intake channel 7 is larger than the pore size of the filter screen 10 located in the inner air intake channel 8.

[0036] In this embodiment, both ends of one side of the filter screen 10 are fixedly connected with limiting rods, and the inner walls of both ends of the outer air intake channel 7 and the inner air intake channel 8 are fixedly connected with limiting seats. The limiting seats are U-shaped, and an insertion hole is opened at one end of the limiting seat near the limiting rod. The limiting rod is inserted into the insertion hole. By setting the limiting rod and the limiting seat, when assembling the filter screen 10, the limiting rod is first aligned with the insertion hole at the limiting seat, and the filter screen 10 is pushed. The displacement of the filter screen 10 can be limited by the limiting seat.

[0037] A cleaning shaft 18 is rotatably connected to the middle of the external air intake channel 7. Multiple knocking plates 19 are fixedly connected to one end of the cleaning shaft 18 inside the external air intake channel 7. A wind-catching roller 20 is fixedly connected to one end of the cleaning shaft 18 outside the external air intake channel 7. A stabilizing cylinder 21 is fixedly connected to the side of the external air intake channel 7 near the wind-catching roller 20 through a bracket. The cleaning shaft 18 passes through the stabilizing cylinder 21. A guide screw 22 is threaded to the top of the stabilizing cylinder 21. An anti-rotation block 23 is fixedly connected to one end of the guide screw 22 inside the stabilizing cylinder 21.

[0038] In this embodiment, the end of the striking plate 19 away from the cleaning shaft 18 is provided with an arc surface. The arc surface allows the striking plate 19 to make smooth contact with the filter screen 10 inside the external air intake channel 7 with less movement interference.

[0039] In this embodiment, multiple wind-catching fan blades are fixedly connected to the outer side of the wind-catching roller 20. The wind-catching fan blades have a hollow structure. By setting the wind-catching fan blades, when there is airflow at the outer air intake channel 7, the wind-catching fan blades can be pushed by the airflow, thereby driving the cleaning shaft 18 to rotate.

[0040] Example 2

[0041] like Figures 1-6 As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes a quick-installation component;

[0042] In this embodiment, the quick-installation component includes:

[0043] Four protective shells 11 are fixedly connected to the two ends of the outer air intake channel 7 and the inner air intake channel 8 respectively. A transmission screw 12 is vertically rotatably connected to the middle of the inner side of the protective shell 11. A displacement rod 13 is threadedly connected to the outer side of the transmission screw 12. Push plates 14 are rotatably connected to both ends of the displacement rod 13. A positioning shaft 15 is rotatably connected to both ends inside each protective shell 11.

[0044] An eccentric plate 16 is fixedly connected to the middle of the positioning shaft 15, and the end of the push plate 14 away from the displacement rod 13 is also rotatably connected to the corresponding eccentric plate 16. A locking block 17 is fixedly connected to the end of the positioning shaft 15 away from the protective shell 11. A locking lug is fixedly connected to the side of the filter screen 10 near the locking block 17, and the locking block 17 is also engaged with the corresponding locking lug.

[0045] In this embodiment, a linear guide rod is fixedly connected to the middle of the interior of the protective shell 11, and the displacement rod 13 is also slidably connected to the outside of the linear guide rod. By setting the linear guide rod, the vertical displacement of the displacement rod 13 can be guided, preventing the displacement rod 13 from rotating with the transmission screw 12.

[0046] In this embodiment, the locking block 17 has an arc-shaped structure, and an arc-shaped hole is provided on the locking lug. The locking block 17 is locked in the arc-shaped hole. Through the arc-shaped structure of the locking block 17, the locking block 17 can be smoothly rotated into the arc-shaped hole by means of the rotation of the positioning shaft 15, thereby realizing the effective positioning of the filter screen 10. Furthermore, the protective shell 11 has a clearance hole at the position corresponding to the positioning shaft 15, and the positioning shaft 15 extends through the clearance hole into the outer air intake channel 7 or the inner air intake channel 8.

[0047] One specific application of the above two embodiments is that, when used as a whole, the external airflow can be exchanged with the gas inside the chamber through the external air intake channel 7 and the internal air intake channel 8 to achieve ventilation inside the chamber. When the external airflow enters the external air intake channel 7, the two filters 10 can block solid objects in the airflow to prevent solid objects from entering the chamber.

[0048] When the filter screen 10 needs to be replaced, first rotate the transmission screw 12. With the transmission screw 12 connected to the displacement rod 13, the displacement rod 13 can move along the transmission screw 12. Since the push plate 14 is connected between the displacement rod 13 and the eccentric plate 16, when the displacement rod 13 moves, it can push the eccentric plate 16 through the push plate 14, causing the positioning shaft rod 15 to drive the locking block 17 to rotate out of the arc-shaped hole, thereby unlocking the filter screen 10. Then the filter screen 10 can be removed and replaced.

[0049] Furthermore, when wind conditions permit, rotating the guide screw 22 causes it to gradually rotate out of the stabilizing cylinder 21, thereby driving the anti-rotation block 23 away from the cleaning shaft 18, thus reducing the friction of the cleaning shaft 18 rotation. When the airflow passes through the wind-catching roller 20, it will push the wind-catching roller 20, causing the cleaning shaft 18 to drive the striking plate 19 to strike the filter screen 10 at the external air intake channel 7, so as to shake off the impurities on the filter screen 10 at the external air intake channel 7.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
