[0021] This utility model provides a vertical shaft aerator, including a mounting plate 101, a gearbox 102, a motor 103, an impeller 104, and an adjusting assembly 105. The adjusting assembly 105 includes a rotating shaft 106, a telescopic shaft 107, a float 108, a locking element 109, and an adjusting member 110. The locking element 109 includes a first threaded rod 112, a threaded sleeve 113, and a locking seat 114. The adjusting member 110 includes a spring 115, an adjusting plate 116, a second threaded rod 117, a worm gear 118, and a worm 119. The rotating shaft 106 has a limiting... The slot 120, the telescopic shaft 107 has a first limiting protrusion 121, the adjusting plate 116 has a second limiting protrusion 122, the buoyancy of the float 108 drives the impeller 104 and the telescopic shaft 107 to rise and fall, so that the height of the impeller 104 can be automatically adjusted with the water level. The locking member 109 is locked into the locking groove 111 to lock the telescopic shaft 107. It can be understood that the above solution can be used to conveniently adjust the position of the impeller 104, and can also be used to adjust the immersion depth of the impeller 104.

[0022] In this specific embodiment, the gearbox 102 is installed on one side of the mounting plate 101, the motor 103 is installed on the gearbox 102, the output end of the motor 103 is connected to the input end of the gearbox 102, and the adjustment component 105 is connected to the output end of the gearbox 102. The motor 103 outputs power to the gearbox 102, and the gearbox 102 drives the adjustment component 105 and the impeller 104 to rotate, thereby achieving the purpose of aeration of sewage.

[0023] The rotating shaft 106 is connected to the output end of the gearbox 102 and passes through the mounting plate 101. The telescopic shaft 107 is slidably connected to the rotating shaft 106 and is located inside the rotating shaft 106. The impeller 104 is fixedly connected to the telescopic shaft 107 and is located at one end of the telescopic shaft 107. The float 108 is fixedly connected to the impeller 104 and is disposed on the impeller 104. The locking member 109 is connected to the rotating shaft 106 and is disposed on the rotating shaft 106. The telescopic shaft 107 has a locking groove 111, which is located on the side of the telescopic shaft 107 near the locking member 109. The adjusting member 110 is disposed on the rotating shaft 106. The density of the float 108 is less than that of water. The adjusting member 110 is elastic. Multiple locking grooves 111 are provided and are evenly distributed on the telescopic shaft 107.

[0024] In use, the power of the motor 103 is output to the rotating shaft 106 through the reduction gearbox 102, causing the rotating shaft 106 to drive the telescopic shaft 107 and the impeller 104 to rotate, thereby aerating the sewage. When the water level changes and the height of the impeller 104 needs to be adjusted, the locking member 109 is rotated to move the locking member 109 out of the locking groove 111. At this time, the telescopic shaft 107 and the impeller 104 can be raised and lowered by the float. The buoyancy provided by float 108 drives the impeller 104 and the telescopic shaft 107 to rise and fall, thereby enabling the impeller 104 to automatically adjust its height according to the liquid level. When the height of the impeller 104 is adjusted to the correct position, the locking member 109 re-engages into the locking groove 111, thereby locking the telescopic shaft 107 and the impeller. This utility model uses the buoyancy of the float 108 to enable the height of the impeller 104 and the telescopic shaft 107 to be adaptively adjusted, thereby improving the adjustment efficiency.

[0025] Secondly, the first threaded rod 112 is rotatably connected to the rotating shaft 106 and is disposed on the rotating shaft 106; the threaded sleeve 113 is threadedly connected to the first threaded rod 112 and is sleeved on the first threaded rod 112; the locking seat 114 is fixedly connected to the threaded sleeve 113 and slidably connected to the rotating shaft 106, and is located at one end of the threaded sleeve 113; the locking seat 114 cooperates with the locking groove 111, and a knob is also installed at one end of the first threaded rod 112. By rotating the knob, the first threaded rod 112 is driven to rotate, and the first threaded rod 112 drives the threaded sleeve 113 to translate, thereby driving the locking seat 114 to translate, so that the locking seat 114 can enter or move out of the locking groove 111, thereby achieving the purpose of locking and unlocking the telescopic shaft 107.

[0026] Meanwhile, the adjusting plate 116 is slidably connected to the rotating shaft 106 and is located inside the rotating shaft 106; the two ends of the spring 115 are respectively connected to the adjusting plate 116 and the telescopic shaft 107, and the spring 115 is located inside the rotating shaft 106.

[0027] In addition, the second threaded rod 117 is rotatably connected to the rotating shaft 106 and threadedly connected to the adjusting plate 116, and passes through the adjusting plate 116; the worm gear 118 is fixedly connected to the second threaded rod 117 and is located at one end of the second threaded rod 117; the worm 119 is rotatably connected to the rotating shaft 106, meshes with the worm gear 118, and is located inside the rotating shaft 106.

[0028] Different water qualities and treatment requirements necessitate different impeller 104 positions. For example, for wastewater containing a large amount of suspended solids, the impeller 104 needs to be placed in a deeper position to reduce interference from suspended solids. In this case, rotating the worm gear 119 drives the worm wheel 118 to rotate, which in turn drives the second threaded rod 117 to rotate. The second threaded rod 117 drives the adjusting plate 116 to descend, causing the adjusting plate 116 to compress the spring 115. When the spring 115 is compressed, the force exerted by the spring 115 on the telescopic shaft 107 increases, thereby causing the telescopic shaft 107 and the impeller 104 to overcome the buoyancy of the float 108 and move towards... The impeller 104 can be moved downwards until the desired depth is reached. Conversely, if it is necessary to reduce the immersion depth of the impeller 104 to improve aeration efficiency, such as when treating relatively clear wastewater, the worm gear 119 can be rotated in the opposite direction. The worm wheel 118 will then rotate in the opposite direction, driving the second threaded rod 117 to rotate in the opposite direction. At this time, the adjusting plate 116 will rise and release the spring 115, reducing the downward pressure of the spring 115 on the telescopic shaft 107. At this time, the buoyancy of the float 108 is greater than the remaining downward pressure of the spring 115. The telescopic shaft 107 and the impeller 104 will then float to the new working position, thereby achieving the purpose of adjusting the position of the impeller 104 according to the specific working conditions.

[0029] Finally, the limiting groove 120 is disposed inside the rotating shaft 106; the telescopic shaft 107 has a first limiting protrusion 121, which is disposed on the side of the telescopic shaft 107 near the limiting groove 120, and the first limiting protrusion 121 cooperates with the limiting groove 120; the adjusting plate 116 has a second limiting protrusion 122, which is disposed on the side of the adjusting plate 116 near the limiting groove 120; the limiting groove 120 limits the movement of the first limiting protrusion 121 and the second limiting protrusion 122, thereby limiting the movement of the telescopic shaft 107 and the adjusting plate 116, so that the telescopic shaft 107 and the adjusting plate 116 can only move along the direction of the limiting groove 120.

[0030] When using the vertical shaft aerator of this utility model, when it is necessary to adjust the position of the impeller 104, the first threaded rod 112 is rotated to drive the threaded sleeve 113 to move, so that the threaded sleeve 113 drives the locking seat 114 to move out of the locking groove 111. At this time, the telescopic shaft 107 and the impeller 104 can move up and down. The height of the impeller 104 can be automatically adjusted by the buoyancy of the float 108. When the height of the impeller 104 is adjusted to the correct position, the first threaded rod 112 is rotated in the opposite direction, so that the locking seat 114 re-enters the locking groove 111, thereby locking the telescopic shaft 107 and the impeller 104. At the same time, when the impeller 104 is at different immersion depths, the position of the adjusting plate 116 is adjusted by rotating the worm gear 119, so that the adjusting plate 116 squeezes or releases the spring 115. Combined with the buoyancy of the float 108, the immersion depth of the impeller 104 can be precisely adjusted.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
