Description

Technical Field

[0001] This utility model relates to the field of soundproof civil defense engineering technology, specifically to a soundproof civil defense engineering protective device. Background Technology

[0002] Civil defense projects, also known as civil air defense projects, refer to underground protective buildings and basements built in conjunction with above-ground buildings to ensure the shelter of personnel and materials, civil air defense command, medical rescue and other needs during wartime. These projects can be used as storage rooms, parking lots, shopping malls and other similar facilities during peacetime, while serving as shelters to protect against attacks by bombs, missiles and other weapons during wartime.

[0003] Civil defense engineering protective equipment refers to specialized equipment used to ensure that civil air defense projects can effectively protect against attacks from various weapons during wartime, including protective doors, airtight valves, other protective equipment, chemical defense equipment, etc.

[0004] In addition to fireproofing, heat insulation, and impact resistance, existing airtight walls for civil defense also need to have good sound insulation to more effectively protect the lives of personnel in emergency situations. Furthermore, through sound insulation, vibration reduction, and other measures, it can also ensure that equipment and facilities can operate normally in both wartime and peacetime. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a soundproof civil defense engineering protection device to solve the technical problem that, in addition to fireproofing, heat insulation, and impact resistance, protective doors also need to have good sound insulation functions in order to more effectively protect the lives of personnel in emergency situations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soundproof civil defense engineering protective device, comprising a main body, with multiple sets of fixed shafts arranged on the outer side of the main body, two sets of fixed shafts having locking blocks at their top ends, one set of fixed shafts having a control plate at its top end, a connecting rod at the bottom end of the control plate, locking blocks on both sides of the connecting rod, a rotary valve arranged on the outer side of the main body, a gear located inside the main body at the bottom end of the rotary valve, multiple sets of toothed plates cooperating with the gears arranged inside the main body, a fixing plate at one end of each toothed plate, and a rubber block at one end of each fixing plate.

[0007] By adopting the above technical solution, when in use, foreign staff will manually pull and turn the valve or push the handle to make the main body fit into the fixed frame that matches it, with the connecting shaft set on its outer side as the axis.

[0008] Then, external staff manually pull the control panel to make it move. At the same time, the connecting rod at the bottom of the control panel will move synchronously. This means that multiple sets of locking blocks are set to lock the fixed frame, thereby forming a fixed structure and preventing the main body from being unstable inside the fixed frame.

[0009] Then, by rotating the rotary valve, the gear at the bottom of the rotary valve is rotated, and the rotation of the gear causes the multiple sets of toothed plates that mesh with it on the outside of the gear to move, thereby moving the fixed plate set at one end of the multiple sets of toothed plates.

[0010] The rubber block on the outer side of one end of the fixing plate is used to open it up and block the gap between the inside of the fixing frame and the main body, thereby reducing noise through sealing.

[0011] Specifically, the outer side of the main body is coated with damping material to suppress the vibration of the main body and the radiation of structural noise;

[0012] Through the above structure, the wall-penetration-proof airtight system not only provides fire resistance, heat insulation, and impact resistance, but also has good sound insulation capabilities. This effectively protects the lives of personnel in emergency situations. Furthermore, through sound insulation, vibration reduction, and other measures, it can also ensure that equipment and facilities can operate normally during both wartime and peacetime.

[0013] Furthermore, one end of the main body is provided with two sets of connecting shafts, and one end of the connecting shaft is fixed with a fixing frame.

[0014] By adopting the above technical solution, the main body can slide along the fixed frame through the connecting shaft, and a seal is achieved.

[0015] Furthermore, the control board and the connecting rod are movably connected via a rotating rod, and the connecting rod and the locking block are movably connected via a rotating rod.

[0016] By adopting the above technical solution, the control board and the connecting rod can be flexibly connected by a rotating rod, thus preventing blockage.

[0017] Furthermore, a handle is provided at one end of the main body, and multiple sets of fixing blocks that cooperate with the fixing blocks are provided inside the main body.

[0018] By adopting the above technical solution, a handle is provided to allow external personnel to easily pull the main body to move its position.

[0019] Furthermore, the main body and the connecting shaft are fixed together by welding, and one end of the toothed plate is provided with multiple sets of teeth that cooperate with the gear.

[0020] By adopting the above technical solution, welding is used to ensure that the main body and the connecting shaft can be fixed, preventing shaking during subsequent use.

[0021] Furthermore, one end of the locking block is provided with a protrusion that cooperates with the fixing frame, and one end of the main body is provided with a protrusion that cooperates with the fixing frame.

[0022] By adopting the above technical solution, the main body and the fixed frame are ensured to fit together by using the protrusions of the main body and the cavity opened inside the fixed frame.

[0023] In summary, the present invention has the following beneficial effects: With the help of an external worker, the main body is rotated along the connecting shaft on its outer side, causing the main body to fit into the fixed frame. Then, by manually controlling the control board, the connecting rod connected to the bottom of the control board rotates synchronously, causing the two sets of locking blocks to engage within the fixed frame. Furthermore, by rotating the rotating valve, the gears inside the valve rotate, causing the multiple sets of gear plates meshing with the gears to open, controlling the rubber block fixed at the top of the gear plates to cooperate with the fixed frame for sealing, thereby achieving the noise reduction function.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The embodiments of this utility model will be described below based on its overall structure.

Multiple sets of fixed shafts 7 are provided on the outer side of the main body 1. Two sets of fixed shafts 7 are provided with locking blocks 5 at their top ends. One set of fixed shafts 7 is provided with a control plate 8 at its top end. The control plate 8 is provided with a connecting rod 6 at its bottom end. In use, foreign staff can manually pull and rotate the valve 4 or push the handle 10 to make the main body 1 fit into the fixed frame 2 with the connecting shaft 3 on its outer side as the axis.

[0034] For example, the connecting rod 6 is provided with locking blocks 5 on both sides, the main body 1 is provided with a rotary valve 4 on the outside, the rotary valve 4 is provided with a gear 12 located inside the main body 1 at the bottom end, and the main body 1 is provided with multiple sets of toothed plates 15 that cooperate with the gear 12. When the external staff manually pulls the control plate 8, the connecting rod 6 at its bottom end will move synchronously, that is, the multiple sets of locking blocks 5 are provided to lock the fixed frame 2 to form a fixation and prevent the main body 1 from being not firmly fixed inside the fixed frame.

[0035] For example, a fixing plate 14 is provided at one end of the toothed plate 15, a rubber block 11 is provided at one end of the fixing plate 14, and two sets of connecting shafts 3 are provided at one end of the main body 1. A fixing frame 2 is fixed at one end of the connecting shaft 3. Then, by rotating the rotating valve 4, the gear 12 provided at the bottom of the rotating valve 4 is rotated. Through the rotation of the gear 12, the multiple sets of toothed plates 15 that mesh with the gear 12 are moved by the rotation of the gear 12, so that the fixing plate 14 provided at one end of the multiple sets of toothed plates 15 is moved.

[0036] For example, one end of the main body 1 is provided with a handle 10, and the inside of the main body 1 is provided with multiple sets of fixing blocks 13 that cooperate with fixing blocks 13. One end of the locking block 5 is provided with a protrusion that cooperates with the fixing frame 2, and one end of the main body 1 is provided with a protrusion that cooperates with the fixing frame 2. The rubber block 11 provided on the outer side of one end of the fixing plate 14 is used to open it up and block the gap between the inside of the fixing frame 2 and the main body 1, thereby reducing noise through sealing.

[0037] The working principle of this utility model is as follows: When in use, foreign staff will manually pull and rotate the valve 4 or push the handle 10 so that the main body 1 is aligned with the connecting shaft 3 set on its outer side as the axis, so that the main body 1 fits into the fixed frame 2 that cooperates with it.

[0038] Then, by manually pulling the control plate 8, the connecting rod 6 at its bottom will move synchronously, which means that the multiple sets of locking blocks 5 will lock the fixed frame 2 to form a fixed position and prevent the main body 1 from being not firmly fixed inside the fixed frame.

[0039] Then, by rotating the rotary valve 4, the gear 12 set at the bottom of the rotary valve 4 is rotated, and through the rotation of the gear 12, the multiple sets of toothed plates 15 that mesh with it on the outside of the gear 12 are moved, and the fixed plate 14 set at one end of the multiple sets of toothed plates 15 is moved.

[0040] The rubber block 11 set on the outer side of one end of the fixing plate 14 is used to open it up and block the gap between the inside of the fixing frame 2 and the main body 1, thereby reducing noise through sealing.

[0041] Specifically, the outer side of the main body 1 is coated with damping material to suppress the vibration of the main body and the radiation of structural noise;

[0042] Through the above structure, the wall-penetration-proof airtight system not only provides fire resistance, heat insulation, and impact resistance, but also has good sound insulation capabilities. This effectively protects the lives of personnel in emergency situations. Furthermore, through sound insulation, vibration reduction, and other measures, it can also ensure that equipment and facilities can operate normally during both wartime and peacetime.
