Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, specifically, it relates to a noise reduction device for environmental protection equipment. Background Technology

[0002] Environmental protection equipment refers to devices used to reduce environmental pollution, protect the ecological environment, and conserve resources. These devices are typically designed to reduce the negative environmental impacts of waste, wastewater, and exhaust gases, or to transform them into more environmentally friendly forms.

[0003] According to the public announcement (CN214837290U), a noise reduction device for environmental protection equipment is disclosed. This technology includes: "a housing with four noise-reducing fans fixed to its inner wall; a rotating U-shaped frame on one side of the housing; fixing blocks fixed to three sides of the outer wall of the housing, and fixing rods fixed to one side of each of the three fixing blocks; two rotating hinges fixed to one side of the housing, with a U-shaped frame fixed to one end of each hinge, and a heat dissipation vent fixed to the inner wall of the U-shaped frame; suction cups fixed to one end of each of the three fixing rods; sound insulation layers fixed to both sides of the inner wall of the housing, with sound insulation panels on one side of each of the two sound insulation layers, and one side of each of the two sound insulation panels fixedly connected to the housing; the four noise-reducing fans deliver air to the heat dissipation vent, which then cools the environmental protection equipment, thus preventing overheating and shutdown, extending the lifespan of the environmental protection equipment, and providing noise reduction functionality to the noise-reducing fans and heat dissipation vent."

[0004] However, while the aforementioned comparative documents reduce the heat generated by the equipment during operation through airflow, the devices cannot provide different heat dissipation and noise reduction methods for different devices. When the air inlet holes on the equipment are too small, the aforementioned comparative documents cannot directly guide the airflow into the interior of the equipment during heat dissipation and noise reduction, which may result in wasted airflow and low efficiency in heat dissipation and noise reduction. At the same time, the device is fixed by suction cups, which is convenient for replacement and disassembly, but the fixing effect is not good. The equipment may vibrate slightly during use, which may cause the device to detach and thus damage the device.

[0005] To address the aforementioned issues, this application proposes a noise reduction device for environmental protection equipment. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a noise reduction device for environmental protection equipment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A noise reduction device for environmental protection equipment includes a housing, an opening and closing plate on one side of the housing, a fixing column fixedly connected to the inner wall of the housing, a fixing shell fixedly connected to the fixing column, a fixing block fixedly connected to the inner wall of the fixing shell, a noise reduction fan fixedly connected to the fixing block, an air inlet fixedly connected to the fixing shell, the air inlet penetrating the housing, a connecting pipe fixedly connected to the side wall of the fixing shell, the connecting pipe penetrating the housing, a folded flexible hose fixedly connected to the connecting pipe, a rotating ring rotatably connected to one end of the folded flexible hose, a suction cup fixedly connected to the outer wall of the rotating ring, and a fixing structure provided on the outer wall of the housing.

[0009] Preferably, a rotating block is rotatably connected to the outer wall of the outer shell, and a fixed structure is provided at one end of the rotating block located outside the outer shell.

[0010] By setting up rotating blocks, the fixed structure can be rotated. The orientation of the fixed structure can be changed by using rotating blocks, which gives the fixed structure more options when fixing the device, thereby improving the practicality of the device.

[0011] Preferably, the fixing structure includes a connector fixedly connected to the rotating block, a telescopic rod fixedly connected to the outer wall of the rotating rod provided on the connector, a groove provided on the connector, a limit groove provided on the connector through the groove, a rotating rod rotatably inserted into the connector through the groove, a fixing strip fixedly connected to the outer wall of the rotating rod, a fixing rod fixedly connected to the rotating rod, and a fixing groove provided on the connector.

[0012] By setting up a fixed structure, the device can be fixed in multiple directions. The rotation of the fixed bar by the rotating rod will drive the rotating rod on the connecting part to rotate through the limiting groove, thereby causing the telescopic rod to rotate. This achieves multi-directional fixation of the device. At the same time, the cooperation between the fixed rod and the fixed groove is used to fix the telescopic rod, thus preventing the device from shaking after it is fixed.

[0013] Preferably, the end of the telescopic rod away from the connector is fixedly connected to a base, and the base has a through hole.

[0014] By setting a base and through holes, the device can be quickly fixed. When fixing the device, the staff can use the fixing strip to quickly fix the base, which makes fixing the telescopic rod faster.

[0015] Preferably, a support shell is fixedly connected to the outer wall of the outer shell, and the outer wall of the folded hose is fitted with the support shell.

[0016] By setting up a support shell, the folded hose can be placed and supported, preventing it from shaking when not in use. This avoids damage to the fixed structure during shaking and thus prevents it from affecting the effectiveness of the device.

[0017] Preferably, the noise-reducing fan has an opening on its outer wall.

[0018] By setting up an opening, the airflow can be guided, allowing the noise-reducing fan to blow air more quickly and intensely, thus avoiding affecting the device's performance.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] By cooperating with the outer shell, opening and closing plate, fixing structure, air inlet, noise reduction fan, fixing block, fixing column, fixing shell, connecting pipe, folding hose, rotating ring, and suction cup, the device can be applied to different equipment. When the air inlet of the equipment is large, the opening and closing of the opening and closing plate can achieve rapid cooling and noise reduction of the equipment. When the air inlet of the equipment is small, the folding hose can be used to cool and reduce the noise of the equipment, thereby avoiding the waste of air power and avoiding affecting the noise reduction effect of the device.

[0021] By setting up a fixed structure, the device can be fixed in multiple directions. The rotation of the fixed bar by the rotating rod will drive the rotating rod on the connecting part to rotate through the limiting groove, thereby causing the telescopic rod to rotate. This achieves multi-directional fixation of the device. At the same time, the cooperation between the fixed rod and the fixed groove is used to fix the telescopic rod, thus preventing the device from shaking after it is fixed. Attached Figure Description

[0037] Working principle:

[0038] The operator fixes the device to the equipment using the fixing structure 3. By pulling the rotating rod 306 outward, the rotating rod 306 can rotate. The rotation of the rotating rod 306 drives the fixing strip 301 to rotate, which in turn drives the telescopic rod 308 to rotate, thus facilitating the fixing of the base 309 to the equipment. After the angle of the device is fixed, the telescopic rod 308 is fixed by the engagement of the fixing rod 307 and the fixing groove 305, thereby preventing changes in the angle of the device. After the device is fixed, the operator selects the noise reduction and heat dissipation method according to the requirements. When the air inlet of the equipment is large, the opening and closing plate 2 can be opened to reduce the temperature and noise of the equipment. When the air inlet of the equipment is small, the operator can connect the folded hose 10 to the air inlet and then connect it to the equipment using the suction cup 12 to fix the folded hose 10. Finally, the opening and closing plate 2 is closed to allow air to accurately enter the equipment, thereby achieving the purpose of cooling and reducing noise of the equipment.
