With a large number of civil defense doors dividing the area, it is very troublesome to check whether each one is functioning properly, and it is also inconvenient for daily management. Therefore, the existing civil defense doors are not convenient to be remotely controlled, which brings inconvenience to monitoring and management work and needs to be further improved. Utility Model Content

[0004] The purpose of this utility model is to provide a regional civil defense door status monitoring and management system to solve the problem that existing civil defense doors are inconvenient to remotely control, which brings inconvenience to monitoring and management work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a regional civil defense door status monitoring and management system, comprising multiple unit civil defense doors, a drive network and a return network, wherein each unit civil defense door comprises a frame and a door panel, and a drive shaft is fixedly installed on the side of the door panel, and the drive shaft is rotatably connected to the surface of the frame.

[0006] A drive box is fixedly installed on the surface of the frame. Inside the drive box, a meshing worm gear and worm are rotatably installed. A hydraulic motor is fixedly installed inside the drive box, and the rotating end of the hydraulic motor is fixedly connected to the worm. The top end of the transmission shaft extends into the drive box, and the worm gear rotates and is sleeved on the surface of the transmission shaft. A transmission assembly is set inside the drive box. The worm gear drives the transmission shaft to rotate through the transmission assembly, realizing remote hydraulic drive of the opening and closing of each door panel. This provides convenience for daily testing of whether the opening and closing of the air defense door is normal, eliminating the need for manual on-site testing of the function of each air defense door unit, making operation more convenient.

[0007] In some embodiments, the transmission assembly includes a sliding sleeve, a hexagonal structural section on the surface of the transmission shaft, a hexagonal hole in the inner hole of the sliding sleeve, the hexagonal hole of the sliding sleeve being slidably mounted on the surface of the hexagonal structural section of the transmission shaft, and meshing grooves on the opposing surfaces of the sliding sleeve and the worm gear to achieve synchronous rotation of the sliding sleeve and the worm gear.

[0008] In some implementations, the transmission assembly further includes an electromagnetic telescopic rod and a toggle ring. The electromagnetic telescopic rod is fixedly connected to the drive box, the telescopic end of the electromagnetic telescopic rod is fixedly connected to the toggle ring, the upper end of the sliding sleeve is rotatably connected to the toggle ring, a drive motor is fixedly mounted on the upper surface of the drive box, the rotating end of the drive motor is fixedly connected to the top end of the transmission shaft, and the sliding sleeve is separated from the worm gear, which facilitates on-site control of the opening and closing of the door panel.

[0009] In some implementations, a Hall sensor is embedded in the surface of the frame, which can detect a signal that the door panel is closed and send it to the control room.

[0010] In some implementation schemes, the frame of the unit air-raid shelter door is embedded in the partition wall separating the air-raid shelter areas. An environmental monitor is fixedly installed on the ceiling of the air-raid shelter area.

Electric valves are installed in both the first and second branch pipes, so that the environmental monitor automatically controls the opening and closing of the air-raid shelter door, which greatly improves the safety between areas within the air-raid shelter project.

[0011] Beneficial effects

[0012] This utility model provides a regional civil defense door status monitoring and management system, which has the following beneficial effects:

[0013] 1. The air defense door status monitoring and management system in this area uses a hydraulic motor installed in the drive box. The rotation of the hydraulic motor drives the door panel to rotate and close. By using the drive pipeline network to transport liquid medium, the liquid medium is introduced into the hydraulic motor in each unit air defense door, driving the hydraulic motor to operate. This enables remote control of the simultaneous opening and closing of each unit air defense door, providing convenience for daily inspection of whether the opening and closing of the air defense doors is normal.

[0014] 2. Under normal circumstances, the sliding sleeve and worm gear of the air-raid shelter door status monitoring and management system are in a meshed state. When the environmental monitor detects unsafe factors in the air-raid shelter area, the environmental monitor sends a feedback signal to the electric valve, which opens the electric valve and can close one or more unit air-raid shelter doors nearby, separating the dangerous area from the safe area.

[0015] When the electromagnetic telescopic rod is energized, the drive sliding sleeve separates from the worm gear. At this time, the door panel can be manually pushed to rotate, or the drive motor can be used to drive the door panel to rotate, so as to realize the independent control of the opening and closing of the door panel and provide convenience for managing the opening and closing status of the door panel.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a regional civil defense door status monitoring and management system, including multiple unit civil defense doors, drive pipe network 1 and return pipe network 2. The unit civil defense door includes a frame 3 and a door panel 4. A drive shaft 5 is fixedly installed on the side of the door panel 4 and is rotatably connected to the surface of the frame 3.

[0024] refer to Figure 4 A drive box 6 is fixedly installed on the surface of the frame 3. A worm gear 7 and a worm 8 are rotatably installed inside the drive box 6. A hydraulic motor 9 is fixedly installed inside the drive box 6. The rotating end of the hydraulic motor 9 is fixedly connected to the worm 8. The top end of the transmission shaft 5 extends into the drive box 6, and the worm gear 7 is rotatably sleeved on the surface of the transmission shaft 5. A transmission assembly is provided inside the drive box 6. The worm gear 7 drives the transmission shaft 5 to rotate through the transmission assembly. That is, when the hydraulic motor 9 rotates, it drives the door panel 4 to open or close.

[0025] The transmission assembly includes a sliding sleeve 10, a hexagonal segment 11 on the surface of the transmission shaft 5, and a hexagonal hole in the inner bore of the sliding sleeve 10. The hexagonal sliding sleeve 10 is located on the surface of the hexagonal segment 11 of the transmission shaft 5. Meshing grooves 12 are provided on the opposing surfaces of the sliding sleeve 10 and the worm gear 7. Figure 5 As shown.

[0026] The transmission assembly also includes an electromagnetic telescopic rod 13 and a toggle ring 14. The electromagnetic telescopic rod 13 is fixedly connected to the drive box 6, and the telescopic end of the electromagnetic telescopic rod 13 is fixedly connected to the toggle ring 14. The upper end of the sliding sleeve 10 is rotatably connected to the toggle ring 14. (Reference) Figure 4 When the electromagnetic telescopic rod 13 pushes the actuating ring 14 downward, the sliding sleeve 10 and the worm wheel 7 mesh together, that is, the sliding sleeve 10 and the worm wheel 7 rotate synchronously. When the electromagnetic telescopic rod 13 pulls the actuating ring 14 upward, the sliding sleeve 10 and the worm wheel 7 separate, that is, the transmission shaft 5 is not constrained by the worm wheel 7 and can rotate freely.

[0027] It should be noted that the meshing transmission between the worm gear 7 and the worm 8 has a self-locking feature, meaning that the worm gear 7 can only be driven to rotate by the rotation of the worm 8, and the worm gear 8 cannot be driven to rotate by the rotation of the worm gear 7. Therefore, after the door panel 4 is driven to flip open in this way, the door panel 4 can maintain the flip angle and prevent the door panel 4 from flipping arbitrarily.

[0028] A drive motor 15 is fixedly installed on the upper surface of the drive box 6. The rotating end of the drive motor 15 is fixedly connected to the top end of the transmission shaft 5. The drive motor 15 is a backup power mechanism prepared for on-site personnel. When the sliding sleeve 10 and the worm gear 7 are separated, the on-site personnel can drive the door panel 4 to flip open or close by driving the drive motor 15.

[0029] A Hall sensor 16 is embedded on the surface of the frame 3. When the door panel 4 is closed, the Hall sensor 16 can detect the signal that the door panel 4 is in a closed state and send it to the control room.

[0030] The frame 3 of the unit air defense door is embedded in the partition wall 19 that separates the air defense area. The drive pipe network 1 and the return pipe network 2 are installed on the wall of the air defense area. The input port of the hydraulic motor 9 is connected to the drive pipe network 1 through the first branch pipe 17, and the output port of the hydraulic motor 9 is connected to the return pipe network 2 through the second branch pipe 18.

[0031] An environmental monitor 20 is fixedly installed on the ceiling of the civil defense area. The environmental monitor 20 is equipped with a temperature sensor, a pressure sensor, a smoke sensor and a harmful gas sensor. Electric valves 21 are installed in both the first branch pipe 17 and the second branch pipe 18.

[0032] Under normal conditions, the sliding sleeve 10 and the worm gear 7 are in a meshed state. When the environmental monitor 20 detects unsafe factors (temperature, smoke, harmful gases) in the civil defense area, the environmental monitor 20 sends a feedback signal to the electric valve 21, which opens the electric valve 21 and drives the pressurized medium in the pipeline network 1 to enter the hydraulic motor 9 through the first branch pipe 17, causing the hydraulic motor 9 to rotate. Then, the pressurized medium flows into the return pipeline network 2 through the second branch pipe 18, which can realize the closure of one or more unit civil defense doors nearby, separating the dangerous area from the safe area. This refers to the environmental monitor 20 automatically controlling the opening and closing action of the civil defense door, which greatly improves the safety between areas within the civil defense project.

[0033] When the electromagnetic telescopic rod 13 is energized, the drive sliding sleeve 10 separates from the worm gear 7. At this time, the door panel 4 can be manually pushed to rotate, or the drive motor 15 can be used to drive the door panel 4 to rotate, so as to realize the independent control of the opening and closing of the door panel 4, which provides convenience for managing the opening and closing status of the door panel 4. This refers to on-site operation.

[0034] The air defense door status monitoring and management system in this area uses a hydraulic motor 9 installed in the drive box 6. The rotation of the hydraulic motor 9 drives the door panel 4 to rotate and close. When the air defense door is being tested, the control room sends an opening signal to the electric valve 21, causing the electric valve 21 to open. The liquid medium is then introduced into the hydraulic motor 9 in each unit air defense door by using the drive pipeline 1 to drive the hydraulic motor 9 to operate. This enables remote control of the simultaneous opening and closing of each unit air defense door, providing convenience for daily testing of whether the opening and closing of the air defense door is normal. It eliminates the need for manual on-site testing of each unit air defense door, making the operation more convenient.

[0035] It should be noted that hydraulically driven door panel 4 can be opened and closed by keeping the drive pipeline 1 pressurized for a long time, which is more cost-effective. If the door panel 4 is opened and closed by electric remote control, the electrical components are more likely to fail during long-term standby and are more affected by the power supply, which cannot meet the requirements of long-term, stable and reliable real-time monitoring for civil defense projects.

[0036] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
