Description

Technical Field

[0001] This invention relates to the field of protective shelter technology, specifically to an underground protective shelter with a reinforced structure. Background Technology

[0002] An underground protective shelter is a building structure used to provide refuge, protection, or storage equipment, typically buried underground or semi-underground. Underground protective shelters are widely used in military, underground construction, mining, engineering construction, and other fields requiring protection and refuge facilities.

[0003] Currently, underground cabins are typically constructed by digging a pit using machinery and then placing the cabin directly into the ground. This results in insufficient stability of the overall structure during fixed use, and the roof's structural strength is inadequate, making it prone to deformation under heavy pressure. Furthermore, the cabins suffer from poor ventilation, negatively impacting the user experience. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide an underground protective cabin with a reinforced structure, which solves the problems of insufficient stability of the overall structure when in fixed use, insufficient structural strength of the cabin roof, and insufficient ventilation of the cabin.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a buried protective cabin with a reinforced structure, comprising a cabin body, two symmetrically distributed positioning piles fixedly connected to the bottom of the cabin body, a top cover fixedly installed on the top of the cabin body, a lid provided at the upper end of the top cover, a ladder fixedly installed inside the cabin body, a box body fixedly connected to the inner side wall of the cabin body, a cover plate slidably sleeved inside the box body, the cover plate slidably connected to the cabin body, a tie rod fixedly connected to the top of the cover plate, a reinforcing mechanism provided on the top cover, a stabilizing mechanism provided on the positioning piles, and a ventilation mechanism provided on the box body.

The plug is slidably connected to the top cover, and a stud is slidably sleeved inside the top plate. The stud is threadedly connected to the top cover. By designing the reinforcing mechanism, the structural strength of the roof of the small house can be improved.

[0007] Preferably, the top cover has a slot inside, and a plug is slidably connected inside the slot. The slot is designed so that the plug can slide inside the slot.

[0008] Preferably, the stabilizing mechanism includes a screw, which is threadedly connected to the inside of the positioning pile. A pressure block is fixedly connected to the bottom of the screw, and an inclined block contacts the outer side of the pressure block. A conical spike is fixedly connected to the outer side of the inclined block, and the conical spike is slidably connected to the positioning pile. A fixing block is fixedly connected to the lower end of the inclined block, and the fixing block is slidably connected to the positioning pile. A slider is slidably sleeved inside the fixing block, and the slider is fixedly connected to the inclined block. A guide rod is slidably sleeved inside the slider, and the guide rod is fixedly connected to the fixing block. A first spring is provided on the outer side of the guide rod. By designing a stabilizing mechanism, the overall structural stability can be improved.

[0010] Preferably, one end of the first spring is fixedly connected to the slider, and the other end of the first spring is fixedly connected to the fixing block. By designing the first spring, the force of the first spring can be applied to the slider.

[0011] Preferably, the ventilation mechanism includes an air pump, which is fixedly connected inside the housing. The air pump has a suction port at its top and an exhaust pipe at its right end. An exhaust port is fixedly connected to the other end of the exhaust pipe and is fixedly connected to the housing. A vent is fixedly connected to the left end of the housing and is fixedly connected to the roof. Multiple evenly distributed filter elements are slidably fitted inside the housing. Adjacent filter elements are connected by a connecting rod. The lower end of one filter element contacts a second spring, and the other end of the second spring is fixedly connected to a support block, which is fixedly connected to the housing.

[0015] The beneficial effects of this invention are as follows: This invention relates to an underground protective cabin with a reinforced structure, which features high stability, high structural strength, and good ventilation. In practical use, compared with traditional underground protective cabins, this underground protective cabin has the following beneficial effects:

[0016] Firstly, by designing positioning piles, the overall structure of the cabin can be fixed to the ground. The screw rods are threadedly connected to the positioning piles. When the screw rods are rotated, the pressure block moves downward. The downward movement of the pressure block can squeeze and push the inclined block, which in turn allows the cone to slide out of the positioning piles. This improves the stability of the positioning pile connection, thereby improving the overall structural stability. By designing the contact between the top plate and the roof, and with the support of the support rods and support seats, the roof can be auxiliaryly supported, which can strengthen the roof structure and prevent the roof from deforming due to excessive pressure, thus affecting the safety of the cabin. Moreover, the top plate is easy to install and operate.

[0017] Secondly, by designing an air pump, the air pump can draw air into the chamber, creating a negative pressure state inside the chamber. This allows outside air to be drawn into the chamber through the vents. With the help of multiple filters, the outside air can be filtered and purified, achieving air circulation and purification inside the chamber and improving the effectiveness of the protective cabin. Furthermore, the cover can be connected and fixed to the chamber by the insertion of ball bearings and grooves. Pulling the lever can remove the cover, making it easy to remove the filters from inside the chamber for convenient filter replacement and maintenance. Attached Figure Description

[0033] The specific implementation process of this invention is as follows: In use, through the action of the positioning pile 3, after the overall structure is hoisted, the overall structure of the cabin can be fixed to the ground by inserting the positioning pile 3. After the insertion is completed, rotating the screw 81 causes the screw 81 to move downwards, which in turn causes the pressure block 82 to slide along the inclined surface of the inclined block 83. The pressure block 82 will squeeze and push the inclined block 83 to move horizontally. The inclined block 83 will drive the slider 87 to slide along the guide rod 88 and squeeze the first spring 89. At this time, the cone 84 will move horizontally and extend out of the positioning pile 3. The cone 84 can be inserted into the ground, which can improve the insertion stability of the positioning pile 3, thereby improving the overall structural stability.

[0034] When the top plate 73 needs to be installed, the top plate 73 is first rotated by the hinge of the support rod 72. Then, the insert block 74 on the top of the top plate 73 is inserted into the slot 75. The top cover 4, together with the support rod 72 and the support base 71, can provide auxiliary support for the top cover 4, which can strengthen the structural strength of the top cover 4 and prevent the roof 1 from deforming due to excessive pressure, thus affecting the safety of the cabin. In addition, the top plate 73 is easy to install and operate.

[0035] When ventilation is required inside the shelter 1, the air pump 91 is activated. The air pump 91 draws air into the enclosure 10 through the suction port 92, creating a negative pressure inside the enclosure 10. This negative pressure then draws outside air into the enclosure 10 through the ventilation port 95. The air is then filtered and purified by the filter element 96. The filtered air enters the exhaust port 94 through the exhaust pipe 93 and is finally discharged into the shelter 1 through the exhaust port 94, achieving air circulation and purification inside the shelter 1 and improving the effectiveness of the protective shelter. When the filter element 96 needs to be removed, the lever 12 is pulled upwards. The lever 12 moves the cover plate 11, which in turn moves the ball bearing 99. 5. Movement: The ball bearing 995 will roll along the arc surface of the groove 996. When the ball bearing 995 is squeezed, it will move horizontally. The ball bearing 995 will drive the slide block 994 and the slide rod 992 to move horizontally. The slide block 994 will squeeze the third spring 993, which can separate the ball bearing 995 from the groove 996. Then the cover plate 11 can be removed from the housing 10 to separate the pressure rod 991 from the filter element 96. At this time, under the elastic action of the second spring 98, the filter element 96 will be pushed upward, which can push the filter element 96 out of the housing 10. Then the filter element 96 can be taken out, which makes it easy to remove the filter element 96 from the inside of the housing 10 for easy replacement and maintenance.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
