Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically a cleaning device for ventilation ducts in community underground garages. Background Technology

[0002] Ventilation ducts are metal or composite pipes used in ventilation and air conditioning projects in industrial and civil buildings. They are a type of municipal infrastructure designed to circulate air and reduce the concentration of harmful gases. However, ventilation ducts that are not cleaned for a long time provide a suitable living environment for harmful bacteria, causing secondary pollution of the air in underground garages. Therefore, it is necessary to clean the inner walls of ventilation ducts regularly.

[0003] Existing patent application number 202222603148.7 discloses a cleaning device for the inner wall of building ventilation ducts, relating to the field of duct cleaning technology. This utility model includes a ventilation duct, a workpiece seat movably disposed inside the ventilation duct, and a drive motor fixedly connected to the side wall of the workpiece seat. An adjusting cleaning component is provided on one side of the output end of the drive motor, and auxiliary components are provided on opposite sides of the workpiece seat. The adjusting cleaning component includes a U-shaped box, a moving block, a soft brush, and a fastening component. A rotating disk is fixedly connected to the output end of the drive motor, and the U-shaped box is fixedly connected to the side wall of the rotating disk away from the workpiece seat. The moving block passes through and is movably disposed within the U-shaped box. This utility model, through its designed adjusting cleaning component, allows for adjustment of the cleaning brush of the cleaning device to ensure a tight fit with the inner wall of the duct according to its size. The designed auxiliary components make pushing the entire device into and out of the ventilation duct more effortless and convenient. Although the above application has many beneficial effects, it still has the following shortcomings: multiple sliding wheels are arrayed on the rotating ring, resulting in poor stability when moving inside the duct, making it prone to tipping to both sides and exhibiting poor stability during use.

[0013] 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.

[0014] Please see Figure 1-4 The present invention provides the following technical solution: Example 1: A community underground garage ventilation duct cleaning device includes an installation ring 1, a remote control motor 2 fixedly installed on one side of the installation ring 1, a rotating rod 3 rotatably connected to the other side of the installation ring 1, a support plate 4 fixedly connected to the rotating rod 3, multiple brushes 5 fixedly connected to the support plate 4, multiple support rods slidably connected to the installation ring 1, a support seat 7 fixedly connected to one end of each support rod 6, a movable wheel 8 rotatably connected to each support seat 7, a remote control motor 9 fixedly installed on the outer wall of each support seat 7, a spring 10 fixedly connected to each support rod 6 position inside the installation ring 1, the output end of each remote control motor 9 fixedly connected to the output shaft of each movable wheel 8, one end of each spring 10 fixedly connected to each support rod 6, and the output end of the remote control motor 2 fixedly connected to one end of the rotating rod 3. In use, the entire mounting ring 1 is inserted into the pipe to be cleaned. The inner wall of the pipe will squeeze the moving wheel 8, causing the moving wheel 8 to drive the support rod 6 to retract into the mounting ring 1. The retracted support rod 6 will compress the corresponding spring 10. The contraction of the spring 10 allows the cleaning device to adapt to the inner diameter of the pipe. Then, the remote control motor 2 and the remote control motor 9 are started. The remote control motor 2 will drive the rotating rod 3, the support plate 4, and the brush 5 to rotate. The remote control motor 9 will drive the moving wheel 8 to rotate. The rotation of the moving wheel 8 will jointly drive the cleaning device to move inside the pipe. The rotating brush 5 will clean the dust accumulated on the inner wall of the pipe. Then, the staff will start the fan inside the duct to discharge the dust that has been cleaned inside the pipe, thus completing the cleaning.

[0015] Example 2: The technical solution of this example, which differs from that of Example 1, includes: a stabilizing mechanism 11 is provided on the side wall of the mounting ring 1 at the position corresponding to the remote control motor 2. The stabilizing mechanism 11 includes a housing 111, multiple mounting seats 112 and multiple guide rods 113. Each mounting seat 112 is rotatably connected to a connecting rod 114. One end of each connecting rod 114 is rotatably connected to a stabilizing wheel 115. A torsion spring 116 is fixedly connected inside the mounting seat 112 at the position corresponding to the output shaft of the connecting rod 114. A moving ring 117 is slidably connected on the housing 111. Multiple pressing rods 118 are fixedly connected on the moving ring 117. A rotating ring 119 is threadedly connected on one side of the housing 111 corresponding to the moving ring 117. Multiple connecting rods 120 are fixedly connected to the side wall of the rotating ring 119. The housing 111 is fixedly connected to the side wall of the mounting ring 1 at the position corresponding to the remote control motor 2. The mounting bases 112 are all fixedly connected to the side wall of the mounting ring 1 at the position adjacent to the housing 111. The guide rods 113 are all fixedly connected to the side wall of the mounting ring 1 at the position corresponding to the extrusion rod 118. One end of the guide rod 113 slides through the corresponding extrusion rod 118. One end of the extrusion rod 118 is arc-shaped. The arc-shaped end of the extrusion rod 118 abuts against the corresponding connecting rod 114. One end of the torsion spring 116 is fixedly connected to the connecting rod 114. In use, insert the external pry bar into the recessed hole on the side wall of the rotating ring 119, and then rotate the rotating ring 119 directly. The rotating ring 119 will move along the thread of the housing 111 towards the mounting ring 1. The rotating ring 119 will drive multiple connecting rods 120 to rotate together. The connecting rods 120 will all rotate inside the moving ring 117 and push the moving ring 117 to move together. The moving ring 117 will drive multiple pressing rods 118 to move together. The movement of the pressing rods 118 is guided by the guide rod 113. During the movement, the arc-shaped ends of the pressing rods 118 will all impact the connecting rod 114. The corresponding position is squeezed, forcing the connecting rod 114 to rotate around the mounting base 112. The rotation of the connecting rod 114 will twist the torsion spring 116, and at the same time, the connecting rod 114 will drive the stabilizing wheel 115 to rotate. At this time, the multiple connecting rods 114 and the stabilizing wheel 115 expand outward like petals opening, until the stabilizing wheel 115 is moved to the same horizontal line as the moving wheel 8. When the moving wheel 8 drives the entire device to move, the stabilizing wheel 115 will follow the movement inside the pipe, thereby providing lateral support for the entire device and preventing the device from tilting during the movement.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
