Description

Technical Field

[0001] The utility model belongs to the technical field of sewage flow pushing, in particular to a submersible flow pushing device for sewage discharge. Background Art

[0002] The submersible flow pusher for sewage discharge pushes sewage or wastewater to a designated location by diving into the water. Its main function is to collect sewage or wastewater from the sewage outlet or water body, and push it to the sewage treatment station or other treatment facilities for treatment through the flow pusher, avoiding the direct discharge of sewage to the environment and reducing water pollution. The principle of this submersible flow pusher is to use an electric motor to drive the impeller or propeller to rotate, generate thrust, and thus push the sewage or wastewater out. By controlling the speed of the motor and the position of the flow pusher, the direction and strength of the flow can be adjusted to meet different sewage discharge needs.

[0003] In the prior art, for example, a submersible flow impeller for sewage treatment provided by Chinese patent publication number CN217119519U drives the impeller to rotate through the submersible flow impeller body, thereby driving the sewage in the sewage pool to move. The hemispherical protective filter can filter the sewage pouring in from the rear, thereby protecting the impeller. The output shaft of the submersible flow impeller body rotates while driving the driving arc rod to rotate, thereby driving the cleaning brush to rotate along the outer wall of the hemispherical protective filter. The cleaning brush contacts the outer wall of the hemispherical protective filter to clean the hemispherical protective filter. However, the above technical solution still has the following problems:

[0004] However, the existing technology still has shortcomings:

[0005] The cleaning brush needs to clean the outer wall of the hemispherical protective filter, which requires the cleaning brush to have the same shape as the protective filter. The friction of the cleaning brush on the protective filter is relatively large, and the cleaning brush is subjected to large torsional and bending forces, resulting in stress concentration. As a result, the end of the cleaning brush away from the output shaft is easily damaged due to the large friction, thereby increasing the risk of breakage and reducing the service life of the cleaning brush. Utility Model Content

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a submersible flow impeller for sewage discharge, which solves the problem that the friction force of the cleaning brush on the protective filter is large when cleaning, and the cleaning brush is easily damaged due to the friction, which reduces the service life.

[0007] To achieve the above-mentioned purpose, according to an embodiment of the utility model, a submersible flow-manipulator for sewage discharge is proposed, comprising a mounting frame, a submersible flow-manipulator body is fixedly mounted on one end of the mounting frame, a driving shaft is fixedly mounted on the output end of the submersible flow-manipulator body, a paddle is fixedly mounted on one end of the driving shaft away from the submersible flow-manipulator body, a protective filter is rotatably connected to the outside of the driving shaft, a turntable is fixedly mounted on the outside of the driving shaft, and a brush rod surrounding the periphery of the protective filter is mounted on the turntable.

[0008] As a further solution of the utility model: the brush rod is rotatably connected to the turntable.

[0009] As a further solution of the utility model: the outside of the driving shaft is rotatably connected with a fixing cover which is fixed to the mounting frame and rotatably connected to the driving shaft, and the fixing cover rotates relatively with the turntable.

[0010] As a further solution of the utility model: the mounting frame is T-shaped.

[0011] As a further solution of the utility model: the number of the brush rods can be multiple.

[0012] As a further solution of the utility model: a brush is fixedly installed on the end side of the turntable facing the protective filter screen.

[0013] As a further solution of the utility model: a bracket is fixedly installed at the bottom end of the mounting frame.

[0014] As a further solution of the utility model: the bracket and the mounting frame are welded.

[0015] As a further solution of the utility model: a driving gear located between the fixed cover and the turntable is fixedly installed on the outside of the driving shaft, an intermediate gear is fixedly connected to one end of the brush rod located between the fixed cover and the turntable, a gear ring is fixedly installed on the inner side wall of the fixed cover, and the intermediate gear is meshed with the driving gear and the gear ring.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By arranging a brush rod and a protective filter, the brush rod rotates around the protective filter, the intermediate gear engages with the driving gear and the gear ring, the rotation of the driving gear drives the intermediate gear and the gear ring to move relative to each other, the intermediate gear rotates on itself, and drives the brush rod to rotate around the protective filter, the brush rod cleans the periphery of the protective filter by self-rotation, simplifies the structure of the brush rod, avoids stress concentration, and reduces the risk of brush rod breakage.

[0018] Preferably, the brush brushes the end side of the protective filter to reduce the residual debris on the end of the protective filter. The bristles of the brush rod are in constant contact with the protective filter, so that the debris on the bristle part of the brush rod gradually falls off due to contact with the protective filter, thereby reducing the residual debris on the bristles of the brush rod.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 and Figure 2As shown, a submersible flow-throwing device for sewage discharge comprises a mounting frame 1, the mounting frame 1 is T-shaped, and a submersible flow-throwing device body 2 is fixedly mounted at one end, a driving shaft 11 is fixedly mounted at the output end of the submersible flow-throwing device body 2, a blade 8 is fixedly mounted at one end of the driving shaft 11 away from the submersible flow-throwing device body 2, a protective filter screen 7 is rotatably connected to the outside of the driving shaft 11, the protective filter screen 7 is fixed to the ground outside to ensure that the protective filter screen 7 does not deviate and rotate, a fixed cover 4 and a turntable 5 are arranged on the outside of the driving shaft 11, the fixed cover 4 and the turntable 5 rotate relative to each other, one side of the fixed cover 4 is fixedly connected to the mounting frame 1, the fixed cover 4 is rotatably connected to the driving shaft 11 to ensure that the fixed cover 4 does not move, the turntable 5 is fixedly connected to the driving shaft 11, and the driving shaft is driven by the submersible flow-throwing device body 2 11 rotates, and after the driving shaft 11 rotates, it drives the paddle 8 to achieve a flow-pushing effect on the sewage, and the driving shaft 11 drives the turntable 5 to rotate. A brush rod 6 is installed on the turntable 5, and the brush rod 6 is connected to the turntable 5 through an axis. Preferably, the brush rod 6 is rotatably connected to the turntable 5, and the brush rod 6 is located at the periphery of the protective filter screen 7. The number of brush rods 6 can be set to be multiple, and a brush 9 is fixedly installed on the end side of the turntable 5 facing the protective filter screen 7. The brush 9 is used to clean the end of the protective filter screen 7. When the driving shaft 11 rotates, the driving shaft 11 plays a cleaning role around the periphery of the protective filter screen 7 through the brush rod 6, so that the friction between the brush rod 6 and the protective filter screen 7 is reduced, and the brush bristles are only driven to clean the periphery of the protective filter screen 7 through the self-rotation of the brush rod 6, thereby avoiding the complex structural design of the brush rod 6, resulting in stress concentration, thereby increasing the risk of breakage.

[0025] As an implementation method in this embodiment, Figure 2 and Figure 3 As shown, in order to improve the supporting capacity of the submersible flow-pushing device body 2, a bracket 3 is fixedly installed at the bottom end of the mounting frame 1, and the bracket 3 is used to support the submersible flow-pushing device body 2. Preferably, the bracket 3 and the mounting frame 1 are welded; a driving gear 12 is fixedly installed on the outside of the driving shaft 11, and the driving gear 12 is located inside the fixed cover 4 and the turntable 5. One end of the brush rod 6 located inside the fixed cover 4 and the turntable 5 is fixedly connected with an intermediate gear 10, and a gear ring 13 is fixedly installed on the inner side wall of the fixed cover 4. The intermediate gear 10 is meshed with the driving gear 12 and the gear ring 13. When the submersible flow-pushing device body 2 drives the driving shaft 11 to rotate When the brush 10 is in motion, the driving shaft 11 drives the active gear 12 to rotate, and the rotation of the active gear 12 drives the intermediate gear 10 and the gear ring 13 to move relative to each other, so that the intermediate gear 10 makes a circular motion along the axis of the driving shaft 11. At the same time, the intermediate gear 10 rotates on itself and drives the brush rod 6 to rotate around the protective filter 7. The brush rod 6 can rotate by itself and clean the periphery of the protective filter 7. During the process of cleaning the protective filter 7 by the brush rod 6, the bristles of the brush rod 6 are in continuous contact with the protective filter 7, so that the debris on the bristle part of the brush rod 6 gradually falls off due to the contact with the protective filter 7, thereby reducing the residue of debris on the bristles of the brush rod 6.

[0026] The working principle of the utility model is as follows: when in use, by starting the submersible flow pusher body 2, the submersible flow pusher body 2 drives the driving shaft 11 to rotate, and the driving shaft 11 drives the blades 8 to push the sewage. At the same time, the rotation of the driving shaft 11 drives the driving gear 12 to rotate, and the intermediate gear 10 is meshed with the driving gear 12 and the ring gear 13. When the submersible flow pusher body 2 drives the driving shaft 11 to rotate, the driving shaft 11 drives the driving gear 12 to rotate, and the rotation of the driving gear 12 drives the intermediate gear 10 and the ring gear 13 to move relative to each other, so that the intermediate gear 10 makes a circular motion along the axis of the driving shaft 11. At the same time, the intermediate gear 10 rotates and drives the brush rod 6 to rotate around the protective filter screen 7. The brush rod 6 cleans the periphery of the protective filter screen 7 by rotating, simplifies the structure of the brush rod 6, avoids stress concentration, and reduces the risk of the brush rod 6 breaking; the bristles of the brush rod 6 are in continuous contact with the protective filter screen 7, so that the debris on the bristle part of the brush rod 6 gradually falls off due to the contact with the protective filter screen 7, thereby reducing the residue of the bristle debris of the brush rod 6.

[0027] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
