Description

Technical Field

[0001] This application relates to the technical field of ceiling systems, and more particularly to a double-layer ceiling structure for maintenance of ultra-clean rooms. Background Technology

[0002] A cleanroom is a well-sealed space that controls parameters such as air cleanliness, temperature, humidity, pressure, and noise as needed. Within a certain space, it reduces airborne particles, harmful gases, bacteria, and other pollutants to below specified levels. It is a specially designed room that controls the temperature, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a certain required range. Regardless of changes in external air conditions, the room can maintain the originally set requirements for cleanliness, temperature, humidity, and pressure.

[0003] Regarding the aforementioned technologies, the inventors believe that existing cleanroom double-layer ceilings generally consist of two ceilings, one above the other. The bottom of the lower ceiling tends to accumulate dust, making cleaning inconvenient, time-consuming, and labor-intensive due to its height. Furthermore, the spacing between the two ceilings is generally fixed and cannot be adjusted according to needs, resulting in poor adaptability. Therefore, to solve the above problems, this application provides a double-layer ceiling structure for the maintenance of ultra-clean rooms. Utility Model Content

[0004] To address the problems mentioned in the background art, this application provides a double-layer suspended ceiling structure for the maintenance of ultra-clean rooms.

[0005] This application provides a double-layer suspended ceiling structure for maintenance of an ultra-clean room, including a first suspended ceiling and a second suspended ceiling located above the first suspended ceiling. An electric telescopic rod is fixedly connected to the bottom right edge of the second suspended ceiling. The output end of the electric telescopic rod is fixedly connected to the top right edge of the first suspended ceiling. A servo motor is fixedly connected to one edge of the first suspended ceiling. The output end of the servo motor is fixedly connected to a lead screw via a coupling. A slider is threaded onto the outside of the lead screw. An L-shaped connecting plate is fixedly installed on the outside of the slider. A cleaning plate is installed on the end of the L-shaped connecting plate away from the slider.

[0006] Preferably, L-shaped mounting ears are fixedly installed on both sides of the top edge of the second ceiling, and the L-shaped mounting ears have mounting holes inside.

[0007] Preferably, a limiting rod is slidably connected at the left edge of the first ceiling, and the top end of the limiting rod is fixedly connected to the bottom of the second ceiling.

[0008] Preferably, the end of the lead screw away from the servo motor is rotatably connected to a support block via a bearing, and the support block is fixedly connected to the top of the first suspended ceiling.

[0009] Preferably, the inner wall of the cleaning plate is tightly fitted to the bottom of the first suspended ceiling.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] 1. By installing an electric telescopic rod, the first ceiling can be raised and lowered, making it convenient for maintenance personnel to inspect and maintain the equipment and pipes above the ceiling without having to dismantle the ceiling on a large scale, thus reducing the impact on the ultra-clean room environment.

[0012] 2. The servo motor drives the lead screw to rotate, which in turn moves the slider and the L-shaped connecting plate. The cleaning plate installed on the L-shaped connecting plate can clean the bottom of the first ceiling, ensuring the cleanliness of the bottom of the first ceiling and preventing dust and other contaminants from entering the ultra-clean room. The design of the inner wall being tightly fitted to the bottom of the first ceiling makes the cleaning more thorough. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0019] Example 1:

[0020] A double-layer suspended ceiling structure for maintenance of ultra-clean rooms, referring to Figure 1 - Figure 4The system includes a first suspended ceiling 1 and a second suspended ceiling 2 located above the first suspended ceiling 1. An electric telescopic rod 3 is fixedly connected to the bottom right edge of the second suspended ceiling 2. The output end of the electric telescopic rod 3 is fixedly connected to the top right edge of the first suspended ceiling 1. By controlling the extension and retraction of the electric telescopic rod 3, the height of the first suspended ceiling 1 can be adjusted. When the electric telescopic rod 3 extends, the second suspended ceiling 2 moves downward to provide maintenance space for maintenance personnel. When maintenance is completed, the electric telescopic rod 3 retracts, and the first suspended ceiling 1 returns to its original position. A servo motor 4 is fixedly connected to one edge of the first suspended ceiling 1. The output end of the servo motor 4 is fixedly connected to a lead screw 5 through a coupling. A slider 6 is threaded onto the outside of the lead screw 5. An L-shaped connecting plate 7 is fixedly installed on the outside of the slider 6. A cleaning plate 8 is installed on the end of the L-shaped connecting plate 7 away from the slider 6. When the servo motor 4 is started, it drives the lead screw 5 to rotate. The external thread of the lead screw 5 is connected to the slider 6. Due to the rotation of the lead screw 5, according to the principle of thread transmission, the slider 6 will move along the axial direction of the lead screw 5. The L-shaped connecting plate 7 fixedly installed on the outside of the slider 6 will also move with the slider 6. The cleaning plate 8 installed on the end of the L-shaped connecting plate 7 away from the slider 6 will clean the bottom of the first ceiling 1 to ensure the cleanliness of the bottom of the first ceiling.

[0021] Reference Figure 1 and Figure 2 L-shaped mounting ears 9 are fixedly installed on both sides of the top edge of the second suspended ceiling 2. The L-shaped mounting ears 9 have mounting holes 10 inside. When installing the double-layer suspended ceiling structure, bolts or other connectors are used to pass through the mounting holes 10 to fix the L-shaped mounting ears 9 to the structure at the top of the building. This design allows the second suspended ceiling 2 to be stably installed above the first suspended ceiling 1, and it is convenient and quick, greatly improving installation efficiency and stability.

[0022] Reference Figure 1 A limiting rod 11 is slidably connected to the left edge of the first ceiling 1. The top of the limiting rod 11 is fixedly connected to the bottom of the second ceiling 2. When the electric telescopic rod 3 drives the second ceiling 2 to move up and down, the limiting rod 11 will move together with the second ceiling 2. Since the limiting rod 11 is slidably connected to the first ceiling 1, this restricts the horizontal displacement of the first ceiling 1, ensuring the stability of the first ceiling 1 during the raising and lowering process of the second ceiling 2, preventing it from shifting, and thus ensuring that the entire double-layer ceiling structure can operate normally.

[0023] Reference Figure 2The end of the lead screw 5 furthest from the servo motor 4 is rotatably connected to a support block 12 via a bearing. The support block 12 is fixedly connected to the top of the first ceiling 1. When the servo motor 4 drives the lead screw 5 to rotate, the support block 12 supports the lead screw 5. Since the lead screw 5 will be subjected to a certain torque and force during rotation, the support block 12 can disperse these forces, making the rotation of the lead screw 5 more stable, reducing the deformation and wear of the lead screw 5, thereby ensuring that the cleaning plate 8 can smoothly clean the bottom of the first ceiling 1 under the drive of the lead screw 5.

[0024] Reference Figure 3 and Figure 4 The inner wall of the cleaning plate 8 is tightly fitted to the bottom of the first ceiling 1. When the servo motor 4 drives the lead screw 5 to rotate, thereby moving the slider 6, the L-shaped connecting plate 7 and the cleaning plate 8, the tight fit design allows the cleaning plate 8 to fully contact the bottom of the first ceiling 1.

[0025] The implementation principle of a double-layer suspended ceiling structure for maintenance in an ultra-clean room according to an embodiment of this application is as follows: The servo motor 4 is preferably of type HBS57, and the electric telescopic rod 3 is preferably of type LX600. The servo motor 4 and the electric telescopic rod 3 are electrically connected to an external power source via a switch. The extension and retraction of the electric telescopic rod 3 is controlled by the switch, which can adjust the height of the first suspended ceiling 1. When the electric telescopic rod 3 extends, the second suspended ceiling 2 moves downward, providing maintenance space for personnel. After maintenance is completed, the electric telescopic rod 3 retracts, and the first suspended ceiling 1 returns to its original position. The servo motor 4 is then started by the switch, driving the lead screw 5 to rotate. The thread opening angle of the lead screw 5 is 20 degrees. The thread self-locking condition is calculated using the following formula: Self-locking condition = coefficient of friction × tan(helix angle) ≥ 1. The slider 6 connected to the external thread of the lead screw 5 moves axially due to the threaded transmission, and the L-shaped connecting plate 7 and the connected cleaning plate 8 fixed on the slider 6 move accordingly. The cleaning process involves cleaning the bottom of the first ceiling 1. L-shaped mounting ears 9 on both sides of the top of the second ceiling 2 have mounting holes 10. During installation, bolts and other connectors are used to pass through and fix the second ceiling 2 to the building top, ensuring its stable installation above the first ceiling 1. The top of the limiting rod 11, which is slidably connected to the left edge of the first ceiling 1, is fixed to the bottom of the second ceiling 2. When the electric telescopic rod 3 drives the second ceiling 2 to rise and fall, it restricts the horizontal displacement of the first ceiling 1, ensuring stability. The end of the lead screw 5 away from the servo motor 4 is rotatably connected to the support block 12 fixed to the top of the first ceiling 1 via a bearing. The support block 12 disperses the torque and force of the lead screw 5 during rotation, making its rotation smoother, reducing deformation and wear, and ensuring smooth cleaning. The inner wall of the cleaning plate 8 is tightly fitted to the bottom of the first ceiling 1. When the servo motor 4 drives the relevant components to move, it fully contacts the bottom of the first ceiling 1, effectively removing dust and impurities and ensuring a clean environment in the ultra-clean room.
