Protective board 30, filter 31, cover plate 32, prefabricated concrete board 33, rock wool board 34, polyester fiber sound insulation board 35, waterproof coating 36 and fire retardant coating 37;

Working principle: When using this spliced prefabricated cabin, as shown in Figure 1, Figure 2, Figure 6 and Figure 7, first select the left cabin 1, right cabin 2 and the required size according to the length requirements of the required prefabricated cabin. Corresponding to the number of inner cabins 3, the left cabin 1 and the right cabin can be moved through the suspension plate 4 fixedly connected to the left cabin 1, the right cabin 2 and the inner cabin 3 through equipment such as a crane. 2 and the inner cabin 3 are hoisted in the position of the prefabricated cabin to be used, so that the bottom plate 5 fixedly connected under the left cabin 1, the right cabin 2 and the inner cabin 3 is placed on the ground, and the inner cabin 3 can be placed on the ground. Inside the left cabin 1 and the right cabin 2, the sealing gasket 6 can then be nested outside the first inserting rod 7 and the second inserting rod 8 fixed on the right sides of the left cabin 1 and the inner cabin 3 respectively, and then The right ends of the first inserting rod 7 and the second inserting rod 8 are respectively engaged with the first limiting groove 9 opened in the inner cabin 3 and the second limiting groove 10 opened in the right cabin 2, and then the The locking bolts 12 fix the connecting plate 11 that fixedly connects the inner ends of the left cabin 1 and the inner cabin 3, and the connecting plate 11 that fixedly connects the inner ends of the inner cabin 3 and the right cabin 2, so that the sealing gasket 6 is single The outer sides of the left cabin 1 and the inner cabin 3 and the inner cabin 3 and the right cabin 2 are closely connected respectively. After there are two or more inner cabins 3, the second one of the adjacent inner cabins 3 can be connected. The insertion rod 8 and the first limiting groove 9 are nested and engaged, and a sealing gasket 6 can be placed in the adjacent inner cabin 3. Finally, screws can be penetrated through the outer end of the bottom plate 5 to fix it to the ground. This makes it easy to complete the splicing and fixing of the prefabricated cabin according to the demand, and facilitates the sealing performance of the sealing gasket 6 to ensure the sealing of the splicing joint;

As shown in Figures 2, 4, 5 and 8, during the use of this prefabricated cabin, symmetrically fitting hatch doors 13 are rotatably connected to the inner rear ends of the left cabin 1 and the right cabin 2, and An infrared sensor 14 is provided above the inner end of the hatch 13. The infrared sensor 14 is inlaid-connected with the left cabin 1 and the right cabin 2 respectively. The infrared sensor 14 is provided with an infrared sensor 14 fixed to the left cabin 1 and the right cabin 2 at the rear and upper side. The baffle 15 with shielding function and the mounting plate 20 of the controller 25 embedded in the right rear end of the right cabin 2 are fixed with screws on the inside of the right rear end of the right cabin 2. Therefore, when the infrared sensor 14 detects the operator in infrared, the controller 25 controls The double-headed motor 18 installed in front of the infrared sensor 14 is working. Since the double-headed motor 18 is fixed to the left cabin 1 and the right cabin 2 through hoops and screws, the outer end of the double-headed motor 18 is connected through a coupling. A symmetrical worm 17 is connected. The outer end of the worm 17 is engaged with a fixed block 19 fixed to the left cabin 1 and the right cabin 2, and the rear side of the worm 17 is engaged with a fixed block 19 fixed to the outer upper side of the hatch 13. Therefore, through the operation of the double-headed motor 18, the worm 17 connected externally can rotate under the engagement limit of the fixed block 19, so that the worm 17 drives the worm gear 16 connected behind it to rotate, thereby facilitating the use of the worm gear 16. The worm gear 16 drives the hatch door 13 to reversely rotate under the limit of the left cabin body 1 or the right cabin body 2, so as to achieve the purpose of automatically opening and closing the hatch door 13 to facilitate the entry and exit of operators;

As shown in Figure 1, Figure 3 and Figure 4, the controller 25 can be used to control the temperature and humidity sensor 21, the smoke sensor 22, the display 23 and the buzzer 24 installed in the installation plate 20 to cooperate, so that the temperature and humidity sensor 21 and The smoke sensor 22 respectively senses the temperature, humidity and smoke in the prefabricated cabin, causes the display 23 to display the temperature, humidity and smoke sensing data, and causes the buzzer 24 to activate the temperature, humidity and smoke sensor 21 when the smoke sensor 22 senses the temperature, humidity and smoke. When the data exceeds the standard, it will sound to provide an alarm reminder. After the temperature and humidity sensor 21 senses that the temperature and humidity in the prefabricated cabin are extremely high, the controller 25 can control the exhaust fans installed outside the left cabin 1 and the right cabin 2. 28 to carry out the operation, since the filter 31 is fixedly connected to the inside of the front and rear ends of the inner cabin 3, the filter 31 is provided with a cover 32 fixed to the inner cabin 3 for shielding, and the exhaust fan 28 is provided with a The water-absorbing plate 26 is nested and fitted with the left cabin 1 and the right cabin 2, and the outside of the exhaust fan 28 is provided with a coaming plate 29 fixed to the left cabin 1 and the right cabin 2. The outer sides of the coaming plate 29 are fixed with screws. There is a protective plate 30, so through the operation of the exhaust fan 28, the external air filtered by the filter 31 can be easily drawn into the prefabricated cabin, and then after being absorbed by the water-absorbing plate 26, it can be discharged through the coaming plate 29 and the protective plate 30. This facilitates ventilation, heat dissipation and moisture absorption inside the prefabricated cabin;

As shown in Figure 1, Figure 3, Figure 4 and Figure 9, and the left cabin 1, right cabin 2, inner cabin 3 and cabin door 13 are all made of concrete prefabricated panels 33, rock wool panels 34, and polyester fiber sound insulation panels. 35. The waterproof coating 36 and the fire-retardant coating 37 are composed from the inside to the outside, so it is convenient for the precast concrete panel 33, the rock wool board 34, the polyester fiber sound insulation board 35, the waterproof coating 36 and the fire-retardant coating 37 to have the same performance. The cabin is convenient for thermal insulation, sound insulation, noise reduction and fire prevention, and can disconnect the fixed connection of the outer hoop and screw of the double-headed motor 18, and carry out maintenance and replacement of the double-headed motor 18. A hole is provided on the left side through the outside of the water-absorbing plate 26. The communication groove 27 in the cabin 1 and the right cabin 2 is therefore convenient for replacing the water absorbing plate 26. The screws of the protective plate 30 and the coaming 29 can be disconnected to facilitate the maintenance of the exhaust fan 28, thereby making it easy to use. It has a long service life.
