Description

Technical Field

[0001] This utility model relates to the field of ventilation duct cleaning technology, specifically a ventilation duct cleaner for coal mines. Background Technology

[0002] Coal mine ventilation ducts are devices used for ventilation in coal mines, primarily for conveying fresh air and removing harmful gases. They are typically made of durable materials to withstand the harsh environment inside mines. The design and material selection of the ventilation ducts directly affect ventilation efficiency and safety.

[0003] A coal mine underground ventilation duct cleaning device, disclosed in CN214813341U, includes a long handle, connecting fish-mouth plates, bracket-shaped scrubbing frames, and strip-shaped mops. The long handle has a hollow structure, with one end fixedly connected to the top surface of a flat plate. A threaded hole (I) is formed on the surface of the flat plate near its bottom. The bracket-shaped scrubbing frame includes an arc-shaped plate, with two opposing connecting fish-mouth plates fixedly connected to the outer middle surface of the arc-shaped plate. Each connecting fish-mouth plate has a threaded hole (II) formed, and the two threaded holes (II) are perpendicular to each other. The flat plate is sequentially threaded with threaded holes (II) and threaded holes (I) and fixedly connected between the two connecting fish-mouth plates in this manner. At least two sets of mounting through holes are evenly formed on the surface of the arc-shaped plate, each set consisting of two threaded holes (III). The strip-shaped mop is placed on the inner side of the arc-shaped plate and fixedly connected to the threaded holes (III). This cleaning device significantly improves the cleaning efficiency of underground ventilation ducts, prevents coal dust accumulation, and enhances underground dust control safety.

[0004] The aforementioned patent proposes that the arc plate is designed with a slightly curved structure to increase the fit and cleaning of the air duct, thereby improving cleaning efficiency. However, in actual use, manually wiping the surface of the air duct with a mop has the disadvantage of being physically demanding. The operator needs to continuously apply force to the cleaning device to achieve a proper fit and cleaning of the air duct, which is quite inconvenient.

[0005] Therefore, we have proposed a coal mine ventilation duct cleaner to solve the problems mentioned above. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-Figure 4 A coal mine ventilation duct cleaner includes a cleaning structure 1, which includes an adjusting component 11 and a cleaning component 13 installed at one end of the adjusting component 11.

[0025] The adjustment component 11 includes a handle 111 and a pneumatic switch 112 installed at one end of the handle 111. A connecting pipe 113 is installed at the outlet end of the pneumatic switch 112. A fixing cylinder 114 is installed at one end of the connecting pipe 113. A shoulder strap 12 is installed on the outer surface of the connecting pipe 113. The inlet end of the pneumatic switch 112 is connected to the air compressor pipe.

[0026] The cleaning component 13 includes a turntable 131 and a connecting rod 132 mounted on the outer surface of the turntable 131. A cleaning brush 133 is mounted on the outer surface of the connecting rod 132. The rotating turntable 131 drives the connecting rod 132 and the cleaning brush 133 to clean the air duct.

[0027] The connecting rod 132 and the cleaning brush 133 are each provided in three sets. The three sets of connecting rod 132 and cleaning brush 133 are evenly arranged on the outer surface of the turntable 131. The three sets of connecting rod 132 and cleaning brush 133 increase the contact area between the cleaning structure 1 and the air duct.

[0028] A T-shaped rotating groove 115 is connected to one end of the fixed cylinder 114. A limiting rotating rod 1141 is movably installed in the middle of the fixed cylinder 114. A threaded hole A1142 is opened in one end of the limiting rotating rod 1141. An impeller 1144 is installed on one end of the outer surface of the limiting rotating rod 1141. A dustproof net 116 is installed on the outer surface of the fixed cylinder 114. The dustproof net 116 facilitates the outflow of air. When the air inside the connecting pipe 113 is discharged into the fixed cylinder 114, it can drive the impeller 1144 to rotate, thereby driving the limiting rotating rod 1141 to rotate.

[0029] A connecting rod 135 is installed at one end of the turntable 131. A threaded hole B137 is provided through the middle of the turntable 131 and the threaded hole B137. The threaded hole B137 is aligned with the threaded hole A1142. A connecting bolt 117 is connected to the internal threads of the threaded hole A1142 and the threaded hole B137. The limiting rotating rod 1141 is installed between the cleaning component 13 using the connecting bolt 117.

[0030] The outer surface of the limiting rotating rod 1141 is provided with slots 1143 on both sides. A matching strip 136 is installed on one end of the connecting rod 135 and on both sides of the threaded hole B137. The matching strip 136 is inserted into the slot 1143 to limit the position between the limiting rotating rod 1141 and the cleaning member 13.

[0031] In this embodiment: a shoulder strap 12 is installed on the connecting pipe 113. When cleaning the air duct, the operator straddles the shoulder strap 12, holds the handle 111 with one hand, and controls the wind-operated switch 112 with the other. The operator holds the cleaning structure 1 with both hands, facilitating control of the cleaning structure 1. The connecting end of the wind-operated switch 112 is connected to the compressed air pipe, using compressed air as the power source. Air is discharged into the interior of the fixed cylinder 114 through the connecting pipe 113. Since the air outlet of the fixed cylinder 114 is located on one side of the impeller 1144, When the air conditioner blows the impeller 1144 to rotate, it can drive the connecting rod 132 and the cleaning brush 133 to rotate through the limiting rod 1141, the insert 136 and the turntable 131, thereby achieving the purpose of cleaning the air duct and realizing mechanical and automated operation. Three sets of connecting rods 132 and cleaning brushes 133 are installed on the outside of the turntable 131 to increase the contact area between the cleaning component 13 and the air duct. Each rotation of the turntable 131 cleans the same part of the air duct three times, greatly improving the efficiency of construction and cleaning effect.

[0032] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figures 2-4 An inner rotating groove 134 is provided on the outer surface of the turntable 131 at the end away from the connecting rod 135. An installation strip 118 is installed on one end of the connecting bolt 117. The installation strip 118 is located inside the inner rotating groove 134 to protect the air duct.

[0033] In this embodiment: Insert your finger into the inner rotating groove 134 and clamp and rotate the mounting strip 118 to cause the threaded end of the connecting bolt 117 to rotate out of the threaded hole A1142 and the threaded hole B137. At this time, the cleaning component 13 and the adjusting component 11 can be separated. After cleaning the cleaning brush 133, insert the insertion strip 136 into the slot 1143. The connecting rod 135 contacts one end of the limiting rotating rod 1141. After the threaded hole B137 and the threaded hole A1142 are aligned, the operator can hold the cleaning component 13 with one hand and the mounting strip 118 with the other hand. Use the threaded end of the connecting bolt 117 to connect the threaded hole B137 and the threaded hole A1142 to connect the adjusting component 11 and the cleaning component 13. Rotate the mounting strip 118 into the inner rotating groove 134 to avoid the rotating mounting strip 118 from wearing down the air duct when using the cleaning structure 1.

[0034] Working principle: Powered by compressed air, the air is discharged into the interior of the fixed cylinder 114 through the connecting pipe 113. The air blows the impeller 1144 to rotate, and the turntable 131 drives the connecting rod 132 and the cleaning brush 133 to rotate, thereby achieving the purpose of cleaning the air duct. This realizes mechanical and automated operation, reduces physical labor, and is equipped with a carrying strap 12 for easy manual carrying.
