Technical Field

[0001] This utility model relates to the field of airflow field technology, specifically to an airflow field inlet silencer. Background Technology

[0002] Air intake silencers in airflow fields are mainly used to reduce noise generated during air circulation. They are widely used in air conditioning systems, ventilation systems, and industrial equipment.

[0003] Chinese patent (publication number: CN205371104U) discloses an air inlet silencer for a local ventilation fan, including a collector and a silencer. The collector has a conical structure, and the silencer has a straight cylindrical shape. The larger diameter end of the collector is fixedly connected to the silencer. The collector includes a collector cylinder, a first support, a first conical cylinder, and a vacuum-formed guide cap. The silencer includes a first outer cylinder, a first inner cylinder, a second outer cylinder, and a first conical reflector. The first outer cylinder and the first inner cylinder are coaxially installed, and the first outer cylinder and the second outer cylinder are fixedly connected to each other by a first arc-shaped reflector. The air inlet silencer achieves sound absorption, sound reflection, and vibration reduction.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation: airflow requires fan drive, fan operation requires motor drive, and motor operation is prone to vibration, resulting in noise. Utility Model Content

[0005] The purpose of this invention is to provide an airflow field inlet silencer to solve the problem in the above-mentioned background technology that airflow needs to be driven by a fan when it flows, and a motor needs to be driven during the operation of the fan, and the motor is prone to vibration and noise during operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an airflow field inlet silencer, comprising an inlet pipe and a silencer pipe, wherein the end of the inlet pipe and the silencer pipe are connected to each other, and a shock-absorbing structure is installed inside the inlet pipe;

[0007] The shock absorption structure includes a mounting block installed inside the air inlet pipe, and the air inlet pipe inside the mounting block is distributed in a ring at equal intervals. A spring is fixedly connected to the end of the mounting block, and a mounting rod is fixedly connected to the end of each spring away from the mounting block.

[0008] The air inlet duct is equipped with an air intake structure that drives the flow of gas.

[0009] Preferably, the mounting rods are arranged in a cross shape inside the air inlet pipe, and two mounting rods are installed inside the air inlet pipe.

[0010] Preferably, the end of the mounting rod away from the spring is fixedly connected to a mounting sleeve, and the mounting rod is distributed in a ring-shaped equidistant structure on the outside of the mounting sleeve.

[0011] Preferably, the air intake structure includes a mounting bracket installed inside the air intake duct, and a turbine is rotatably connected to the center of each mounting bracket.

[0012] Preferably, the turbine is provided with two turbines symmetrically distributed at both ends of the mounting sleeve, and a dual-shaft motor is fixedly connected inside the mounting sleeve.

[0013] Preferably, the dual-axis motor has two output ends, and four transmission belts distributed in an annular pattern are fixedly connected to the outside of each output end, and the end of the transmission belt away from the dual-axis motor is connected to the turbine.

[0014] Preferably, the silencer pipe has an internal cavity, and the cavity is set as a vacuum environment. A sound insulation layer is fixedly connected to the inner side of the silencer pipe, and the sound insulation layer is made of porous rubber material. Vibration damping rings are fixedly connected to the outer sides of both the air inlet pipe and the silencer pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This type of airflow field inlet silencer, because the mounting sleeve and the mounting rod are connected to each other, the mounting sleeve will transmit the vibration to the spring. At this time, the spring absorbs the vibration generated by the mounting sleeve through its own deformation, thereby preventing the vibration generated by the mounting sleeve during operation from causing the equipment to resonate and reducing the noise generated by the mounting sleeve during operation.

[0017] Furthermore, as the air flows inside the silencer, the cross-section of the pipe through which the air flows will gradually increase. At this time, the airflow will be dispersed to a larger area, which will slow down the airflow and prevent sudden changes in air pressure and velocity from causing noise. Attached Figure Description

[0025] 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.

[0026] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: an airflow field inlet silencer, comprising an inlet pipe 1 and a silencer pipe 2, wherein the ends of the inlet pipe 1 and the silencer pipe 2 are connected to each other, and a shock-absorbing structure is installed inside the inlet pipe 1; the shock-absorbing structure includes a mounting block 4 installed inside the inlet pipe 1, and the mounting block 4 is arranged in a ring with equal spacing on the inner side of the inlet pipe 1; a spring 6 is fixedly connected to the end of the mounting block 4, and a mounting rod 5 is fixedly connected to the end of each spring 6 away from the mounting block 4; an air intake structure for driving gas flow is installed inside the inlet pipe 1; the mounting rods 5 are arranged in a cross shape inside the inlet pipe 1, and two mounting rods are installed inside the inlet pipe 1; a mounting sleeve 7 is fixedly connected to the end of the mounting rod 5 away from the spring 6, and the mounting rods 5 are arranged in a ring with equal spacing on the outer side of the mounting sleeve 7.

[0027] During the operation of the device, air is drawn in from inside the air inlet pipe 1 through the air intake structure inside the air inlet pipe 1, and air is discharged into the air flow field from inside the silencer pipe 2. During the operation of the air intake structure, the dual-axis motor 10 will drive the two turbines 9 to rotate, thereby drawing outside air into the air inlet pipe 1. The dual-axis motor 10 will generate vibration during operation, and the vibration of the dual-axis motor 10 will be transmitted to the mounting sleeve 7. Since the mounting sleeve 7 and the mounting rod 5 are connected to each other, the mounting sleeve 7 will transmit the vibration to the spring 6. At this time, the spring 6 absorbs the vibration generated by the mounting sleeve 7 through its own deformation, thereby preventing the vibration generated by the mounting sleeve 7 during operation from causing the equipment to resonate and reducing the noise generated by the mounting sleeve 7 during operation.

[0028] Example 2: Based on Example 1, an air intake structure is also disclosed, the specific structure of which is as follows: The air intake structure includes a mounting bracket 8 installed inside the air intake pipe 1, and a turbine 9 is rotatably connected in the middle of each mounting bracket 8; two turbines 9 are symmetrically distributed at both ends of the mounting sleeve 7, and a dual-axis motor 10 is fixedly connected inside the mounting sleeve 7; the dual-axis motor 10 is provided with two output ends, and four transmission belts 11 distributed in a ring at equal intervals are fixedly connected to the outside of each output end, and the end of the transmission belt 11 away from the dual-axis motor 10 is connected to the turbine 9; the silencer pipe 2 has a cavity 12 inside, and the cavity 12 is set as a vacuum environment; a sound insulation layer 13 is fixedly connected to the inside of the silencer pipe 2, and the sound insulation layer 13 is made of porous rubber material; vibration damping rings 3 are fixedly connected to the outside of both the air intake pipe 1 and the silencer pipe 2.

[0029] During the operation of the dual-axis motor 10, the dual-axis motor 10 will drive the transmission belt 11 to rotate around its output end. At this time, multiple transmission belts 11 will be intertwined. After the transmission belts 11 are intertwined, they will drive the turbine 9 to rotate inside the mounting bracket 8. The rotation of the turbine 9 will draw air into its air inlet pipe 1. When the transmission belts 11 transmit the power of the dual-axis motor 10, multiple transmission belts 11 form a soft connection. When the dual-axis motor 10 drives the turbine 9 to rotate, it can prevent the vibration of the dual-axis motor 10 from causing the turbine 9 to vibrate. This reduces the noise generated when the dual-axis motor 10 is running and improves the stability of the turbine 9 during operation.

[0030] After passing through the air inlet duct 1, the air will enter the silencer duct 2. Due to the overall conical structure, as the air flows through the silencer duct 2, the cross-section of the pipe through which the air flows will gradually increase. At this time, the airflow will be dispersed to a larger area, which will slow down the airflow and prevent noise caused by sudden changes in air pressure and flow rate.

[0031] The silencer tube 2 has a vacuum environment with a cavity 12 inside, which can effectively reduce the noise generated when the gas inside the silencer tube 2 flows. The sound insulation layer 13 is made of porous rubber material, which can effectively insulate the sound. At the same time, vibration damping rings 3 are installed on the outer side of the entire silencer. The vibration damping rings 3 can buffer the external vibration source to a certain extent and reduce the noise generated by the equipment during operation.

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
