Description

Technical Field

[0001] This application belongs to the field of noise reduction device technology, and in particular relates to a noise reduction device for road construction. Background Technology

[0002] Road construction generates significant noise pollution, disrupting people's daily lives and rest, harming their health, and greatly impacting the lives and work of nearby residents. This necessitates the use of noise reduction devices to mitigate the noise. However, existing noise reduction devices typically rely on a soundproof panel and a support frame for noise reduction.

[0003] A Chinese patent with publication number CN220377567U discloses a noise reduction device for road construction, including a device base. The device base has storage slots on both sides, and fixed brackets are movably installed on the front and rear surfaces of the storage slots. A noise reduction plate is fixedly installed on the upper surface of the device base, and a ventilation frame is fixedly installed on the side surface of the noise reduction plate.

[0004] While the aforementioned noise reduction device improves wind resistance, the noise reduction plate is relatively low, making it easy for noise to propagate from above. Furthermore, the height of the noise reduction plate cannot be adjusted. This issue needs to be addressed. Summary of the Invention

[0005] The purpose of this application is to address the aforementioned technical problems by providing a noise reduction device for road construction, which increases the height range of noise reduction that the noise reduction device can achieve by adjusting the overall height of the noise reduction plate.

[0006] This application provides a noise reduction device for road construction, comprising:

[0007] The base is equipped with a column base;

[0008] The noise reduction plates are fixed and placed on both sides of the base;

[0009] The movable noise reduction plate is movably installed on the base and placed between two fixed noise reduction plates;

[0010] The adjustment mechanism is located between the base and the movable noise reduction plate;

[0011] The adjustment mechanism is equipped with a drive motor, the base is equipped with a locking mechanism for locking the movable noise reduction plate, the column base is equipped with a T-slot, and the fixed noise reduction plate is equipped with a plug-in part corresponding to the T-slot.

[0012] The base is placed on the ground. By inserting the connector into the T-slot, the fixed noise reduction plate is installed on the base. The movable noise reduction plate is placed between the two fixed noise reduction plates. The movable noise reduction plate is raised and lowered by the adjustment mechanism, thereby adjusting the noise reduction height of the noise reduction device. When noise reduction is needed, the movable noise reduction plate is raised to ensure noise reduction performance. When there is strong wind or the construction site is stopped and noise reduction is not needed, the movable noise reduction plate is lowered and retracted. After the movable noise reduction plate is raised, it is locked by the locking mechanism to improve the stability of the movable noise reduction plate after being raised. The adjustment mechanism is driven by a drive motor.

[0013] Furthermore, the adjustment mechanism includes:

[0014] Adjust the gears to drive the rotation via the drive motor;

[0015] The adjusting rack is mounted on the movable noise reduction plate and corresponds to the adjusting gear.

[0016] The adjusting gear is driven by a drive motor. The adjusting gear meshes with the adjusting rack. When the adjusting gear rotates, it causes the adjusting rack and the movable noise reduction plate that is installed and connected to it to move. The movable noise reduction plate is equipped with adjusting gears and adjusting racks at both ends, and they are driven at the same time when the movable noise reduction plate moves.

[0017] Furthermore, the locking mechanism includes:

[0018] The locking teeth correspond to the adjusting rack.

[0019] The movable rod has two hinges to the locking teeth;

[0020] The movable rod is hinged to the column base, and a locking cylinder is hinged between the movable rod and the column base. The movable noise reduction plate is locked by the locking teeth cooperating with the adjusting rack.

[0021] After the movable noise reduction plate is raised, the movable rod is rotated by the locking cylinder, which moves the locking teeth and engages with the adjusting rack to lock the movable noise reduction plate, preventing it from sliding down and further improving the stability of the movable noise reduction plate after it is raised.

[0022] Furthermore, the base is provided with a top mounting seat, and the adjustment mechanism and locking mechanism are both installed in the top mounting seat. The movable noise reduction plate is provided with a limiting part.

[0023] By installing the adjustment mechanism and locking mechanism on the top mounting base, the overall structural strength of the noise reduction device is improved, and the stability of the movable noise reduction plate during adjustment and movement is enhanced. The travel of the noise reduction plate's lifting height is limited by the limiting part, thereby improving the stability of the movable noise reduction plate during movement and adjustment.

[0024] Furthermore, the top mounting base is provided with rollers symmetrically distributed with the adjusting gear, the movable noise reduction plate is provided with a connecting part, the adjusting rack is mounted on the connecting part, the connecting part is provided with an extension part, and the extension parts of adjacent connecting parts abut against each other.

[0025] The stability of the movable noise reduction plate is further improved by having one side of the connecting part abut against the roller and the other side cooperates with the adjusting gear and adjusting rack. Adjacent connecting parts abut against each other and separate from each other through the extension part, so that each movable noise reduction plate can be raised and lowered independently, making the installation and adjustment of the noise reduction device more convenient.

[0026] Furthermore, both the fixed noise reduction plate and the movable noise reduction plate are provided with noise reduction grooves with a trapezoidal cross-section.

[0027] By using noise reduction grooves to improve the refraction of noise transmission angle and multiple absorption barriers, the attenuation rate of noise in air and solid transmission is increased, thereby improving the noise reduction effect.

[0028] The beneficial effects of this application are:

[0029] 1. By inserting the connector into the T-slot, the fixed noise reduction plate is installed on the base, and the movable noise reduction plate is placed between the two fixed noise reduction plates.

[0030] 2. The movable noise reduction plate is raised and lowered by the adjustment mechanism, thereby adjusting the noise reduction height of the noise reduction device. When noise reduction is needed, the movable noise reduction plate is raised to ensure noise reduction performance. When there is strong wind or the construction site is shut down and noise reduction is not needed, the movable noise reduction plate is lowered and retracted.

[0031] 3. After the movable noise reduction plate is raised, it is locked by a locking mechanism to improve the stability of the movable noise reduction plate after it is raised. The adjustment mechanism is driven by a drive motor. Attached Figure Description

When noise reduction is needed, the movable noise reduction plate 300 is raised to ensure noise reduction performance. When there is strong wind or the construction site is stopped and noise reduction is not needed, the movable noise reduction plate 300 is lowered and retracted. After the movable noise reduction plate 300 is raised, it is locked by the locking mechanism 500 to improve the stability of the movable noise reduction plate 300 after being raised.
