CONCRETE EMBODIMENT
[0017] The technical scheme in the utility model will be described clearly and completely in combination with the drawings in the utility model.
[0018] The utility model discloses an innovative sills height can be flexibly adjusted civil air defense door, and its core component includes a comprehensive design civil air defense door main body 100. Civil air defense door main body 100 is carefully divided into several key parts: the stable ground 110 as the support foundation, the vertical installation of civil air defense door frame 111 on it, this frame not only plays the support effect, still built-in advanced drive arrangement, the core function of this device is accurate control civil air defense door body 113's lifting movement, ensures under different security needs can quick response. Doorway 112 is cleverly arranged in the internal space of civil air defense door frame 111, and its size is strictly matched with civil air defense door body 113, so that civil air defense door body 113 can accurately and accurately close or open doorway, satisfies the actual needs of civil air defense engineering.
[0019] The sill adjusting mechanism is one of the highlights of the design, which is composed of an adjusting chamber 114, a high-efficiency hydraulic cylinder 115, and a liftable sill body 116. The adjusting chamber 114 is carefully excavated on the surface of the ground 110, providing a flexible lifting space for the sill body 116. The hydraulic cylinder 115, with its powerful driving force, is stably installed inside the adjusting chamber 114. Through precise hydraulic control, it can easily realize the up-and-down movement of the sill body 116 in the chamber, thereby adjusting the sill height according to actual needs and improving the adaptability and flexibility of the civil air defense door.
[0020] The sill adjusting mechanism is mainly composed of an adjusting chamber, a hydraulic cylinder, and a sill body. When the sill height needs to be adjusted, the hydraulic cylinder starts to work. The hydraulic cylinder generates a pushing or pulling force through the piston and hydraulic oil inside it, which acts on the sill body, allowing it to rise and fall in the adjusting chamber.
[0021] Specifically, when the piston of the hydraulic cylinder moves forward, it pushes the sill body upwards; conversely, when the piston moves backward, the sill body descends. The size of the pushing or pulling force of the hydraulic cylinder can be adjusted by controlling the flow and pressure of the hydraulic oil, thereby realizing precise control of the lifting of the sill body.
[0022] Embodiment Two:
[0023] On the basis of Embodiment One, Embodiment Two makes a number of beneficial improvements to enhance the stability and sealing performance of the civil air defense door. First, guide grooves 118 are added on both sides of the doorway 112, and at the same time, guide strips 117 are firmly installed on both sides of the civil air defense door body 113. This sliding cooperation design of guide strips and guide grooves greatly ensures the stability and accuracy of the civil air defense door body during movement, effectively preventing safety hazards caused by shaking or misalignment.
[0024] In order to further enhance the sealing effect, the outer wall of the civil air defense door body 113 is specially provided with a first sealing strip 119, and the inner wall of the door hole 112 is correspondingly provided with a second sealing strip 120. When the civil air defense door body is completely closed, the two sealing strips are tightly attached to form an invincible sealing barrier, effectively preventing the intrusion of harmful substances from the outside and improving the overall protection capability of the civil air defense project.
[0025] In addition, the bottom of the civil air defense door body 113 is specially designed with a fitting groove 121, which is ingeniously matched with the door sill body 116. When the door sill body is driven to rise into the fitting groove by the hydraulic cylinder, not only the firmness of the civil air defense door closing is further increased, but also the stability and impact resistance of the overall structure are improved.
[0026] In terms of driving device, a combination of motor, reducer and screw rod is adopted. The motor accurately transmits power to the screw rod through the reducer, and the screw rod is connected to the back of the civil air defense door body through a nut pair, so as to realize the stable lifting of the civil air defense door body along the vertical direction of the door hole. The civil air defense door body is made of high-strength steel plate or reinforced concrete material, which not only has extremely high strength and durability, but also can maintain its stability and functionality in extreme environment, providing a solid safety guarantee for civil air defense projects.
[0027] Finally, it should be pointed out that: first, in the description of the present application, it should be pointed out that, unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, which can be mechanical connection or electrical connection, or the communication between two elements, or direct connection, "up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may change;
[0028] Secondly: the utility model discloses the embodiment of the drawings, only relate to the structure involved in the embodiment of the present disclosure, other structures can refer to the usual design, in the case where there is no conflict, the same embodiment and different embodiments of the utility model can be combined with each other;
[0029] Finally: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
