Description

Technical Field

[0001] The utility model relates to the technical field of tunnel fans for underground pipe galleries, in particular to a tunnel fan component for underground pipe galleries. Background Art

[0002] It is a management system that centralizes the city's electricity, communications, broadcasting, water supply and drainage, heat, gas and other pipelines and cables into an underground tunnel, facilitating the management and maintenance of each system and effectively preventing damage to the road surface caused by failures of individual systems. The underground pipe gallery is ventilated by fans.

[0003] For example, the Chinese authorized patent with announcement number CN215633885U (an explosion-proof fan for underground pipe gallery) includes a fan housing, a support bracket fixedly installed in the fan housing, a drive motor fixedly installed at the end of the support bracket in the fan housing, a fan blade fixedly installed at the output end of the drive motor, a cleaning mechanism installed on the fan housing, the cleaning mechanism including a handle, a movable shaft, an upper end cover, a cleaning notch, a stain outlet and a lower end cover, a clamping mechanism installed on the fan housing at the upper end cover and the lower end cover, the clamping mechanism including a positioning base, a connecting buckle, a limiting hole, a connecting clamping seat and a limiting latch, the cleaning notch is opened at the top of the fan housing, the stain outlet is opened at the bottom of the fan housing, and the upper end cover is movably installed in the cleaning notch. The underground pipe gallery explosion-proof fan described in this utility model belongs to the field of explosion-proof fans and can facilitate users to clean dust accumulated in the fan.

[0004] However, after long-term use, dust will adhere to the surface of the motor of the existing underground corridor tunnel fan. Cleaning through the surface opening has a limited cleaning range, and the fan needs to be moved out of the installation wall as a whole, which is inconvenient to clean. When taking out the motor separately, the person needs to support the motor by hand to prevent the motor from falling when removing the fan cover, which is inconvenient to disassemble. Therefore, it does not meet the existing needs. In this regard, we have proposed a tunnel fan assembly for underground corridors. Utility Model Content

[0005] The purpose of the present utility model is to provide a tunnel fan assembly for an underground pipe gallery, so as to solve the problem proposed in the above-mentioned background technology that dust will adhere to the surface of the motor of the existing underground pipe gallery after long-term use, and the cleaning is carried out through the surface opening, but the cleaning range is limited, and the fan needs to be moved out of the installation wall as a whole, which is inconvenient to clean. When taking out the motor separately, the person needs to support the motor by hand to avoid the motor falling when removing the fan cover, which is inconvenient to disassemble.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tunnel fan assembly for an underground pipe gallery, comprising: a fan sleeve, an installation cavity is provided inside the fan sleeve, and the installation cavity passes through the fan sleeve from front to back, a fan assembly is provided at the inner center of the installation cavity, the inner wall of the installation cavity is provided with a movable groove, the outer wall of the fan assembly is threadedly fixed with a motor support frame, three motor support frames are provided, one end of the motor support frame is integrally formed with a support frame fixing seat, and one side surface of the support frame fixing seat is provided with a movable seat that slides along the movable groove.

[0007] Preferably, a first mounting hole is provided at one end of the inner wall of the movable groove, a second mounting hole is provided at the other end of the inner wall of the movable groove, and three movable grooves are provided and are equidistantly distributed.

[0008] Preferably, fixing bolts are provided at both ends of the support frame fixing seat, and one end of the fixing bolt passes through the support frame fixing seat and is threadedly connected to the second mounting hole.

[0009] Preferably, a protective grid is provided at the front opening of the installation cavity, the protective grid is fixed to the fan sleeve by external screws, the fixed end of the protective grid is inserted into the movable groove, and the protective grid is made of stainless steel.

[0010] Preferably, the front and rear ends of the fan cover are both provided with fixed frames, the front surface of the fixed frame is provided with fixing holes, and the fixing holes pass through the fixed frame front and back.

[0011] Preferably, the fan assembly includes an asynchronous motor, the output end of the asynchronous motor is provided with a fan blade seat, and the outer wall of the fan blade seat is fixed with a fan blade by hot melting.

[0012] Preferably, the rear end of the movable groove is sealed, and the front end of the movable groove is open.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model provides a movable groove on the inner wall of the installation cavity, and provides a movable seat on one side of the support frame fixed seat, so that the fan assembly is installed inside the installation cavity of the fan sleeve. During installation, the fan blades of the fan assembly face the open end of the movable groove. When the fan assembly is placed, the movable seat slides along the movable groove, which has a limiting effect on the installation of the fan assembly, avoids adjusting the direction back and forth during installation, and also prevents the fan assembly from tipping over, thereby improving stability. After the movable seat is inserted into the movable groove, it is only necessary to grasp the motor support frame in the vertical direction and then push the motor support frame to realize the movement of the fan assembly. There is no need to hold the asynchronous motor by hand, which saves time and effort, improves flexibility, and pushes the motor support frame straight When it cannot be pushed anymore, it is fixed with fixing bolts. When the surface of the asynchronous motor needs to be cleaned, the protective grid is first removed, and then the fixing bolts are removed. The motor support frame can be pulled to drive the fan assembly to move out of the fan cover without manual support or removal of the fan cover, which saves time and effort and improves convenience. It solves the problem that dust will adhere to the surface of the motor of the existing underground tunnel corridor after long-term use. Cleaning is carried out through the form of surface openings, and the cleaning range is limited. In addition, the fan needs to be moved out of the installation wall as a whole, which is inconvenient to clean. When taking out the motor separately, personnel need to support the motor with their hands to avoid the motor falling when removing the fan cover, which is inconvenient to disassemble.

[0015] 2. By setting the rear end of the movable groove to a sealed form and the front end of the movable groove to an open form, the movement of the movable seat is limited at one end. When it is moved to a point where it cannot move, it is fixed with a fixing bolt to achieve a positioning and fixing effect. The fixed end of the protective grid is inserted into the movable groove, which also has a quick positioning effect on the installation of the protective grid and improves the convenience of installation.
