Description

Technical Field

[0001] This utility model relates to the field of building ventilation technology, specifically to a ventilation system for a silent chamber. Background Technology

[0002] A soundproof cabin is a functional building assembled on-site using prefabricated components. Soundproof cabins are widely used in temporary offices, emergency rescue, and modular housing. Their core requirements are to strictly control noise transmission and achieve efficient ventilation in a limited space while meeting the environmental requirements for personnel activities or equipment operation.

[0003] In the existing technology, the ventilation system of the soundproof chamber has the following prominent problems: First, traditional ventilation devices mostly adopt a straight-through air duct design, which does not optimize the ventilation path according to the structural characteristics of the sound insulation panel, resulting in noise being directly transmitted into the chamber during air flow, which cannot meet the low noise requirements; Second, the ventilation control module is mostly set independently and lacks intelligent adjustment function, which cannot dynamically adjust the ventilation parameters according to the environment inside the chamber, thus limiting the functional expandability and user comfort of the soundproof chamber. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation system for soundproof chambers, which solves the problems of insufficient noise control and low level of intelligent control in existing prefabricated soundproof chamber ventilation systems by optimizing the duct structure, improving the splicing method and integrating an intelligent control module.

[0005] The technical solution provided by this utility model is a ventilation system for a soundproof chamber, including a soundproof chamber body. The soundproof chamber body is formed by combining multiple sound insulation panels and connecting components to form a "U"-shaped main frame. A switch door is provided at the front of the main frame, and a viewing window is provided at the rear of the main frame. The sound insulation panels have multiple through cavities for ventilation along their thickness direction. A controller and adjustment panel that are electrically connected to each other are provided on the inner side of the side wall of the main frame. A first air outlet is provided on the bottom side of the side wall, and a second air outlet communicating with the first air outlet is provided on the upper outer side of the same side wall. A fan is provided on the top side of the main frame, and an air supply outlet communicating with the fan is provided on the bottom of the opposite side.

[0006] As a preferred technical solution of this utility model, a lighting lamp is provided at the top of the main frame, and the lighting lamp is located on the top of the sound insulation plate on the side of the controller, which has an opening communicating with the adjustment panel and the controller.

[0007] As a preferred technical solution of this utility model, the controller is embedded in the bottom of the side wall of the main frame. The controller integrates an MCU control module, a power regulation module and a wireless transmission module. A wiring cable connecting to the outside is provided at the controller on the outside of the main frame.

[0008] As a preferred embodiment of this utility model, the first air outlet and the second air outlet have the same width, the fan and the air supply outlet have the same width, and they are located in the same through cavity.

[0009] As a preferred technical solution of this utility model, the main frame is composed of a single sound insulation board or multiple sound insulation boards spliced ​​together in the width direction. When splicing, the two ends of the sound insulation board are respectively the corresponding insertion protrusion and insertion groove.

[0010] As a preferred technical solution of this utility model, the connecting component includes an edge strip located on the side of the sound insulation panel and a connecting strip located at the corner of the sound insulation panel. The two end faces of the connecting strip are provided with T-shaped connecting grooves. The through cavity of the sound insulation panel is fixed to the connecting groove by connecting posts and three-locking devices.

[0011] As a preferred technical solution of this utility model, the connecting column is slidably inserted into the through cavity, and the shape of the connecting column matches the shape of the through cavity. The middle of the connecting column is provided with a grid-like support frame composed of mutually perpendicular intersecting stiffeners, and a three-lock is fixedly inserted into the center position of the grid-like support frame.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] 1. High-efficiency noise reduction: By setting a through cavity in the thickness direction of the sound insulation board as a ventilation channel, the resonance sound absorption principle of the cavity structure is used to reduce the noise transmission efficiency, thus solving the problem of insufficient noise control in traditional straight-through air ducts.

[0014] 2. Flexible and airtight structure: It adopts the splicing method of plug-in protrusions / grooves and T-shaped connecting grooves, combined with the sliding plug-in of connecting columns and grid support frame, which simplifies the installation process and improves the splicing airtightness, avoids air leakage, and can be expanded in size as needed;

[0015] 3. Intelligent control integration: The controller integrates MCU, power regulation and wireless transmission module, which can dynamically adjust the fan speed and lighting status through the adjustment panel or remote terminal to realize intelligent adjustment of ventilation parameters;

[0016] 4. High space utilization: The fan, air supply outlet, and first / second air outlet are all located in the same through cavity, optimizing the ventilation path, reducing the space occupied by the air duct, and improving the flexibility of the layout of the functional areas inside the soundproof chamber.

[0035] Working principle

[0036] 1. Air circulation: External air is driven by the fan 12 into multiple through-cavities 7 and then sent to the air outlet 13. The air is then sent into the interior of the soundproof chamber 1 through the air outlet 13 to meet the breathing needs of personnel. At the same time, the turbid air in the soundproof chamber is collected to the bottom of the side wall by air pressure, enters the through-cavity 7 through the first air outlet 10, and is finally discharged outside the chamber through the second air outlet 11 (forming an internal and external air circulation mode).

[0037] 2. Noise Reduction Mechanism: When air flows in the through cavity 7, the cavity structure generates a resonant sound absorption effect (sound absorption coefficient ≥0.6) on mid-to-high frequency noise (1000-5000Hz), reducing the transmission of noise into the chamber; low frequency noise (<1000Hz) disperses energy through the grid-like support frame 24 of the connecting column 22, further attenuating the noise intensity, and finally achieving a noise level of ≤45dB in the chamber (under an ambient noise level of 55dB).

[0038] 3. Autonomous adjustment: The MCU module receives data from the adjustment panel 9 to adjust the speed of the fan 12, the intensity of the lighting 14, or to control other devices in the soundproof chamber 1 (such as air conditioners and humidifiers, which require additional interfaces) for adjustment.

[0039] 4. Remote monitoring: The wireless transmission module uploads environmental data to the cloud platform. Users can view real-time curves and historical records through a mobile APP, and remotely modify set parameters (such as temperature and humidity range) to achieve unattended intelligent ventilation management.

[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
