Description

Technical Field

[0001] This utility model relates to the field of quantum communication equipment installation, and in particular to a multi-stage absorption and noise reduction device for quantum communication installation. Background Technology

[0002] The multi-stage absorption and noise reduction device for quantum communication installation is a device that reduces the impact of noise, vibration, etc. through multi-stage filtering and noise suppression technology. It can improve the purity of quantum signals, ensure stable transmission of quantum states, and ensure communication reliability and security. It is suitable for quantum key distribution, quantum network construction, and high-precision laboratory environments.

[0003] Existing multi-stage noise reduction devices for quantum communication installations lack sound-absorbing cotton protection devices. Without these devices, dust may enter the sound-absorbing cotton over time, causing blockages in its internal structure and leading to a decrease in effectiveness.

[0004] Therefore, in view of the problem that the existing multi-stage absorption and noise reduction devices for quantum communication installation lack sound-absorbing cotton protection devices, and that dust enters the sound-absorbing cotton causing blockage and resulting in reduced effectiveness, there is an urgent need to design a new type of multi-stage absorption and noise reduction device for quantum communication installation. Summary of the Invention

[0005] To overcome the problem that existing multi-stage noise reduction devices for quantum communication installations lack sound-absorbing cotton protection devices, dust can enter the sound-absorbing cotton and cause blockage, leading to a decrease in effectiveness.

[0006] The technical solution of this utility model is as follows: a multi-stage absorption and noise reduction device for quantum communication installation, including a main chamber; it also includes a torsion roller and a plastic film. The outside of the main chamber is wrapped with sound-absorbing cotton. The outside of the main chamber is equipped with symmetrical mounting frames. Sliding grooves are opened on the opposite surfaces of the two mounting frames. A torsion roller is installed between the two mounting frames. The outer surface of the torsion roller is connected to the plastic film. A handle is installed at the front end of the plastic film. A magnetic plate is installed at the right end of the plastic film. A metal plate is installed between the two mounting frames. A symmetrical sliding frame is installed at the upper end of the main chamber. A sealing door is provided at the upper end of the main chamber to close the opening of the main chamber.

[0007] Preferably, by installing sound-absorbing cotton and sealing doors, external interference to the main chamber is reduced. A torsion roller is used to wind and retract the plastic film. After the sound-absorbing cotton is installed on the outside of the main chamber, the plastic film is pulled by a handle, allowing it to unfold around the main chamber along a groove. This, combined with the two mounting frames, forms a cover to enclose the sound-absorbing cotton, preventing dust from clogging it and reducing its effectiveness. Furthermore, by using magnetic plates and metal plates, the unfolded plastic film is attracted to the metal plates by the magnetic plates, preventing it from being retracted by the torsion roller. This protects the sound-absorbing cotton and addresses the problem of existing multi-stage noise reduction devices for quantum communication installations lacking a sound-absorbing cotton protection device. Without this protection, dust may enter the sound-absorbing cotton over time, causing blockages and reducing its effectiveness.

[0008] Preferably, a transmission module is installed inside one side of the sliding frame, and a knob is connected to the front end of the transmission module on the outside of the sliding frame.

[0009] Preferably, the transmission module includes a lead screw installed inside a sliding frame on one side, with a sliding element threaded onto the lead screw. When the knob is turned, the sliding element can be moved by rotating the lead screw.

[0010] Preferably, the sliding component includes a main slider mounted on the outer surface of the lead screw. The left end of the main slider is connected to the right end of the sealing door. When the main slider moves, it causes the sealing door to move closer to or away from the main compartment.

[0011] Preferably, a limiting rod is installed inside the sliding frame on the other side, and a secondary slider is slidably connected to the outer surface of the limiting rod. The right end of the secondary slider is connected to the left end of the sealing door. The movement of the sealing door can drive the secondary slider to slide on the limiting rod.

[0012] Preferably, springs are installed at the four corners of the lower surface of the main compartment, with rubber feet installed at the lower ends of the springs, and vibration filtering components are installed inside each of the four springs.

[0013] Preferably, the vibration filtering assembly includes a shock-absorbing rod installed inside the spring, with its upper and lower ends fixedly connected to the rubber support and the main chamber, respectively, for buffering vibration.

[0014] The beneficial effects of this utility model are:

[0015] 1. This device unfolds along the slide groove with a plastic film, forming a sealed cover with the double mounting frame to protect the internal sound-absorbing cotton. The unfoldable plastic film forms a dust barrier, effectively preventing dust from clogging the sound-absorbing cotton and maintaining the stability of noise reduction performance. The double frame slide groove structure ensures the accuracy of the plastic film unfolding trajectory and ensures the integrity of the sealed cover. The modular design improves the efficiency of sound-absorbing cotton maintenance and replacement.

[0016] 2. This device achieves positioning and locking through the magnetic attraction between the magnetic plate and the metal plate, preventing the torsion roller from automatically retrieving the plastic film. Through magnetic fixation and roller retrieval mechanism, the protective cover can be quickly unfolded and stored, improving the ease of operation. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-5This utility model provides an embodiment: a multi-stage absorption and noise reduction device for quantum communication installation, including a main chamber 1; it also includes a torsion roller 5 and a plastic film 6. The outer side of the main chamber 1 is wrapped with sound-absorbing cotton 2. The outer side of the main chamber 1 is equipped with symmetrical mounting frames 3. The opposite surfaces of the two mounting frames 3 are provided with sliding grooves 4. The torsion roller 5 is installed between the two mounting frames 3. The outer surface of the torsion roller 5 is connected to the plastic film 6. The front end of the plastic film 6 is equipped with a handle 8. The right end of the plastic film 6 is equipped with a magnetic plate 9. A metal plate 10 is installed between the two mounting frames 3. By setting the sound-absorbing cotton 2, the noise reduction effect of the external noise on the main chamber is reduced. To mitigate internal interference, a torsion roller 5 is used to wind and retract the plastic film 6. After the sound-absorbing cotton 2 on the outside of the main chamber 1 is installed, the handle 8 is used to pull the plastic film 6, causing it to unfold around the main chamber 1 along the slide groove 4. This, together with the two mounting frames 3, forms a cover to enclose the sound-absorbing cotton 2, preventing dust from clogging it and reducing its effectiveness. Furthermore, by setting up a magnetic plate 9 and a metal plate 10, the plastic film 6 is attracted to the metal plate 10 by the magnetic plate 9 after unfolding, preventing it from being retracted by the torsion roller 5. This achieves the purpose of protecting the sound-absorbing cotton 2.

[0025] Please see Figures 1-2 In this embodiment, a transmission module is installed inside the sliding frame 11 on one side. The front end of the transmission module is located on the outside of the sliding frame 11 and connected to a knob 12. The transmission module includes a lead screw 13 installed inside the sliding frame 11 on one side. A sliding member is threaded on the lead screw 13. When the knob 12 is rotated, the lead screw 13 can be rotated to drive the sliding member to move. The sliding member includes a main slider 14 installed on the outer surface of the lead screw 13. The left end of the main slider 14 is connected to the right end of the sealing door 15. When the main slider 14 moves, it drives the sealing door 15 to move closer to or away from the main compartment 1. When the knob 12 is rotated, the lead screw 13 is rotated. When the lead screw 13 rotates, the rotation of the main slider 14 is restricted by the sliding frame 11, thereby driving the main slider 14 to move. When the main slider 14 moves, it drives the sealing door 15 to move, thereby achieving the purpose of opening the main compartment 1 to install the quantum communication device.

[0026] Please see Figures 1-5In this embodiment, a limiting rod 16 is installed inside the sliding frame 11 on the other side. A secondary slider 17 is slidably connected to the outer surface of the limiting rod 16. The right end of the secondary slider 17 is connected to the left end of the sealing door 15. The movement of the sealing door 15 can drive the secondary slider 17 to slide on the limiting rod 16. During the movement of the secondary slider 17, the limiting rod 16 restricts the degree of freedom of the secondary slider 17, thereby providing support for the other side of the sealing door 15, thus achieving the purpose of assisting the movement of the sealing door 15. Springs 26 are installed at the four corners of the lower surface of the main compartment 1. Rubber feet 25 are installed at the lower ends of the springs 26. The internal components of spring 26 are equipped with vibration filtering components, including shock absorber rods 24 installed inside spring 26. The upper and lower ends of shock absorber rods 24 are fixedly connected to rubber feet 25 and main chamber 1, respectively, to buffer vibration. Spring 26 and shock absorber rods 24 work together to absorb high-frequency vibrations generated during the operation of internal hardware. Through their own deformation, they convert vibration energy into heat energy or elastic potential energy, reducing the amplitude of vibration transmitted to main chamber 1, thereby avoiding resonance. Rubber feet 25 isolate the chassis from direct contact with the ground and suppress low-frequency vibrations of main chamber 1 itself, thereby achieving the purpose of noise reduction on the lower side of main chamber 1.

[0027] During operation, the rubber support 25, shock absorber 24, and spring 26 at the lower end of the main chamber 1 provide stable support for the main chamber 1 and reduce external interference to the lower end of the main chamber 1. Then, the sound-absorbing cotton 2 is placed on the outside of the main chamber 1. After the placement is completed, the plastic film 6 is pulled out and wrapped around the main chamber 1 by the handle 8. Finally, the unfolded plastic film 6 is fixed by the magnetic plate 9 and the metal plate 10, thus protecting the sound-absorbing cotton 2. Then, the knob 12 is turned, and the sealing door 15 is opened with the cooperation of the limit rod 16 and the auxiliary slider 17, so that the quantum communication device can be installed inside the main chamber 1. After the installation is completed, the direction is turned to close the sealing door 15. After the sealing door 15 is closed, it isolates the upper side of the main chamber 1 from external interference.

[0028] Through the above steps, by installing sound-absorbing cotton 2 and sealing door 15 around the main chamber 1, the influence of the external environment on the interior of the main chamber 1 is effectively isolated. Then, the plastic film 6 is directionally wound using the torsion roller 5. After the sound-absorbing cotton 2 on the outside of the main chamber 1 is laid, the operator pulls the plastic film 6 with the handle 8, so that it is fully unfolded around the outer wall of the main chamber 1 along the preset slide 4 path. The unfolded plastic film 6 and the mounting frames 3 on both sides together form a sealed cover, completely wrapping the sound-absorbing cotton 2 inside, thereby preventing dust from entering the pores of the sound-absorbing cotton 2 and avoiding the attenuation of acoustic performance caused by dust accumulation. After the plastic film 6 has finished unfolding, the magnetic attraction between the magnet plate 9 and the metal plate 10 can accurately lock the unfolded state of the plastic film 6, preventing the elastic restoring force of the torsion roller 5 from causing the plastic film 6 to shrink back. This achieves continuous physical protection for the sound-absorbing cotton 2. This structure innovatively solves the problem of pore blockage caused by long-term exposure of the sound-absorbing cotton 2 in traditional quantum communication noise reduction devices, ensuring that the acoustic material maintains stable noise reduction performance.
