Description

Technical Field

[0001] The present application relates to the technical field of submersible flow thrusters, and in particular to a submersible flow thruster for sewage treatment in water conservancy projects. Background Art

[0002] The sewage treatment submersible flow propeller is a device specially used for sewage treatment, usually used in sewage treatment plants or sewage treatment facilities. This type of flow propeller is usually driven by an electric motor or pneumatic drive to stir and mix solid particles and waste in sewage for better treatment and decomposition. The function of the flow propeller is to evenly distribute the waste in the sewage through stirring and mixing, promote the decomposition of organic matter by microorganisms in the sewage, and accelerate the sewage treatment process.

[0003] Referring to the utility model with announcement number CN215877534U, a stable submersible flow propeller for sewage treatment in water conservancy projects includes a support plate, a lifting assembly and an auxiliary flow propeller assembly, wherein a lifting assembly is fixed on an inner wall of one side of the support plate, and an auxiliary flow propeller assembly is fixed on an outer wall of one side of the support plate; the lifting assembly includes a lifting slot, a motor, a threaded rod, a lifting plate, a threaded hole and a submersible flow propeller, wherein a lifting slot is opened on an inner wall of one side of the support plate, a motor is embedded and installed on the inner wall of the bottom end of the lifting slot, a threaded rod is rotatably connected to the inner wall of the top end of the lifting slot, and one end of the output shaft of the motor is fixed to the threaded rod; the utility model adopts a lifting device, which can lift and lower the device by the motor, thereby increasing the lifting space and thus improving the lifting effect; an auxiliary flow propeller is also adopted, which can assist the sewage in propulsion when the submersible flow propeller is propulsing the sewage, thereby avoiding sludge deposition and improving the propulsion effect.

[0004] The above patent adopts a method of combining a threaded rod with a threaded hole to adjust the lifting state of the submersible flow propeller underwater so that the submersible flow propeller can obtain a larger stroke. However, under the above transmission method, due to the wear effect between the thread teeth, the anti-rust coating on the surface of the threaded rod placed underwater is easily worn after a period of use, resulting in the metal of the threaded rod being directly exposed under the aeration tank, which greatly shortens the life of the device. In response to the above problems, a submersible flow propeller for sewage treatment in water conservancy projects is proposed to solve the above problems. Utility Model Content

[0012] Furthermore, the middle portion of the connecting wheel is provided with a number of rollers, and the traction rope is wound around the outside of the plurality of rollers.

[0013] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0014] The submersible flow propeller for sewage treatment in a water conservancy project provides a sliding guide for a slide plate by providing a guide groove on a fixed plate, thereby achieving the traction of the submersible flow propeller to change its height position in the sewage tank. At the same time, the slide plate is adjusted in height by the transmission of a traction rope through a transmission wheel and a connecting wheel, thereby reducing the wear caused by the threaded transmission and increasing the service life of the device.

[0019] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0020] See also Figure 1-3 In this embodiment, a submersible flow propeller for sewage treatment in a water conservancy project includes a fixed plate 1 immersed in a water treatment pool of the water conservancy project, a slide plate 2 installed on the fixed plate 1, and a submersible flow propeller 6 installed on the slide plate 2, wherein the fixed plate 1 has anti-corrosion and anti-biological attachment properties, thereby being able to adapt to the environmental characteristics of sewage treatment.

[0021] In this embodiment, the bottom of the skateboard 2 is a trapezoidal protrusion, and a guide groove 3 corresponding to the bottom of the skateboard 2 is opened on the surface of the fixed plate 1. The skateboard 2 slides in the guide groove 3, so that the activity stability of the submersible flow propeller 6 relative to the fixed plate 1 is improved.

[0022] It should be noted that an extension piece is installed on the skateboard 2 for installing the submersible flow pusher 6. The extension piece includes a support plate 4 fixedly installed in the middle of the skateboard 2 and a fixed plate 5 fixedly connected to the support plate 4. The submersible flow pusher 6 is fixedly installed on the fixed plate 5.

[0023] Furthermore, a support frame is fixedly mounted on the fixed plate 5 for stabilizing the submersible flow propeller 6 .

[0024] In this embodiment, two connecting wheels 9 are rotatably mounted on the skateboard 2, and two transmission wheels 7 are rotatably mounted on the fixed plate 1. A traction member is provided between the transmission wheel 7 and the connecting wheel 9 for pulling the skateboard 2 to change its position relative to the fixed plate 1.

[0025] In this embodiment, the traction member includes fixed blocks 8 fixedly mounted on both ends of the fixed plate 1 and a traction rope 10 fixedly connected between the two fixed blocks 8. The traction rope 10 and the two connecting wheels 9 and the transmission wheel 7 are mutually sleeved for transmission traction.

[0026] Specifically, by rotating the transmission wheel 7, the traction rope 10 can drive the two connecting wheels 9 to rotate. At this time, since the position of the traction rope 10 is restricted at both ends of the fixed block 8, the distance between the two connecting wheels 9 relative to the fixed block 8 is changed during rotation, thereby driving the skateboard 2 connected to the connecting wheels 9 to slide and change its position relative to the fixed plate 1.

[0027] It should be noted that a reciprocating motor 11 is fixedly mounted on the rear side of the fixed plate 1 , and the output end of the reciprocating motor 11 is fixedly connected to a transmission wheel 7 , which can drive the transmission wheel 7 to rotate back and forth through the reciprocating motor 11 .

[0028] It is understandable that the reciprocating motor 11 is a submersible motor, and the outside is protected by a double-layer shaft seal, thereby ensuring the service life of the reciprocating motor 11.

[0029] In this embodiment, the middle part of the connecting wheel 9 has a number of rollers 12, and the traction rope 10 is wound around the outside of the rollers 12. The rotation of the rollers 12 relative to the connecting wheel 9 can reduce the wear of the traction rope 10 relative to the connecting wheel 9.

[0030] By setting a fixed plate 1 to open a guide groove 3 to provide guidance for the sliding plate 2, it is possible to pull the submersible flow propeller 6 to change its height position in the sewage tank. At the same time, by setting the slide plate 2, the height is adjusted by the traction rope 10 through the transmission wheel 7 and the connecting wheel 9, thereby reducing the wear caused by the threaded transmission and improving the service life of the device.

[0031] The working principle of the above embodiment is:

[0032] By placing the fixed plate 1 in the sewage treatment tank, the reciprocating motor 11 is controlled so that the reciprocating motor 11 drives a transmission wheel 7 connected to the output end to rotate. The transmission wheel 7 drives the externally connected traction rope 10 to transmit along the surface of the transmission wheel 7 during rotation. At this time, the traction rope 10 also drives the connecting wheel 9 to rotate, thereby changing the length of the traction rope 10 between the connecting wheel 9 and the two fixed blocks 8. At this time, the skateboard 2 connected to the connecting wheel 9 slides and changes its position relative to the guide groove 3, so that the position of the skateboard 2 relative to the fixed plate 1 is adjusted, that is, the up and down reciprocating height adjustment of the skateboard 2 is realized, so that the height of the submersible flow propeller 6 installed on the skateboard 2 can be adjusted.

[0033] By setting a fixed plate 1 to open a guide groove 3 to provide guidance for the sliding plate 2, it is possible to pull the submersible flow propeller 6 to change its height position in the sewage tank. At the same time, by setting the slide plate 2, the height is adjusted by the traction rope 10 through the transmission wheel 7 and the connecting wheel 9, thereby reducing the wear caused by the threaded transmission and improving the service life of the device.
