Description

Technical Field

[0001] The utility model relates to the technical field of pump equipment, in particular to a submersible axial flow pump with a movable track. Background Art

[0002] An axial flow pump is a water pump that uses the rotation of the impeller to generate axial thrust on the liquid, while a submersible axial flow pump is a water pump that combines a motor and an axial flow pump into one body and works as a whole submerged in water. It can transport large amounts of liquid and is suitable for occasions that require large flow drainage or water supply.

[0003] In the existing technology, submersible axial flow pumps are mainly vertical structures and are installed in supporting wells. Each pump station must be specially designed, and there is a large amount of civil construction, which takes 3-6 months. The construction period is long and the investment cost is high. In addition, the pump can only be installed in the well and used in fixed occasions. Due to the position limitation of the well, it can only be used in fixed places and cannot be moved as the liquid level drops. The installation height cannot be adjusted. Therefore, in response to the above problems, we propose a new type of submersible axial flow pump with a movable track. Utility Model Content

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: Figure 1-Figure 2 As shown, the utility model provides a submersible axial flow pump with a movable track, comprising an axial flow pump body 2, a water outlet pipe 3 is provided on the outside of the axial flow pump body 2, a bracket 6 is provided below the water outlet pipe 3, and movable rollers 7 are installed at the bottom of the bracket 6 near the four corners, bearings 8 are installed inside the movable rollers 7, and pressure covers 9 are installed outside the bearings 8. A filter screen 1 is installed at the water inlet position of the axial flow pump body 2, and the filter screen 1 is used in conjunction with the water outlet pipe 3, and a push rod device 4 is installed on the outside of the water outlet pipe 3, and the inner end of the push rod device 4 conflicts with the axial flow pump body 2.

[0021] The effect achieved by the entire embodiment 1 is that the water outlet pipe 3 in the present device is used in conjunction with the axial flow pump body 2, and is mainly used to pump out the liquid and then transport it outward through the water outlet pipe 3. The top rod device 4 outside the water outlet pipe 3 can be extended inward after adjustment, and is mainly used to fix the axial flow pump body 2 inside the water outlet pipe 3. The cross section of the bracket 6 is an inverted U-shape, and the bottom corner is a convex bifurcation shape, which is used to install the moving roller 7. By adding bearings 8, it is used to reduce the friction force when the moving roller 7 rotates and improve the rotation flexibility. The pressure cover 9 is mainly used to fix the moving roller 7. When the moving roller 7 needs to be fixed, the pressure cover 9 is driven by rotating the threaded rotating rod to squeeze the side of the moving roller 7 to prevent it from rotating. Loosening the pressure cover 9 can make the moving roller 7 resume rotation. The setting of the filter screen 1 is mainly used to avoid the axial flow pump itself During the pumping process, larger impurities in the liquid enter the body 2 and cause damage to the equipment. When in use, it can be placed on the embankment and river slope for use. After a slide rail is set under the moving roller 7 of the device, the moving rollers 7 on both sides can be placed on the slide rail for use. During use, a push-pull force can be directly applied to the axial flow pump body 2. At this time, the moving roller 7 under the axial flow pump body 2 will roll in the slide rail, thereby facilitating the movement of the axial flow pump body 2. The mobility is high during use, and installation and maintenance are very convenient. When the water level drops, the axial flow pump body 2 can be moved to the appropriate water level along the slide rail for use, which expands the practical working conditions at the pump station. At the same time, the overall construction period of this device is short and the cost is low. It can be combined with other installation methods, such as auto-coupling installation, hard pipe and hose installation, and has high flexibility in use.

[0022] Example 2: Figure 1-Figure 2 As shown, the outside of the water outlet pipe 3 is fixedly connected to an outlet pipe 5, the cable of the axial flow pump body 2 passes through the outlet pipe 5 and extends outward, and the water outlet pipe 3 is horizontally welded and fixed to the top of the bracket 6.

[0023] The effect achieved by the entire embodiment 2 is that the outlet pipe 5 is mainly used to protect the connecting cables of the axial flow pump body 2. When the cable of the axial flow pump body 2 passes through the outlet pipe 5 and is sealed, it has the effect of fixing and protecting, avoiding damage and pollution caused by pulling of the cable.

[0024] Working principle: When in use, this device can be placed on embankments and river slopes for use. After setting a slide rail under the moving roller 7, the moving rollers 7 on both sides can be placed on the slide rail for use. During use, the push-pull force can be directly applied to the axial flow pump body 2. At this time, the moving roller 7 under the axial flow pump body 2 will roll in the slide rail, thereby facilitating the movement of the axial flow pump body 2. The mobility is high during use, and the installation and maintenance are very convenient. When the water level drops, the axial flow pump body 2 can be moved along the slide rail to the appropriate water level for use, which expands the use conditions of the pump station site. At the same time, the overall construction period of this device is short and the cost is low. It can be combined with other installation methods, such as autocoupling installation, hard pipe and hose installation, and has high flexibility in use. In addition, the outlet pipe 5 is mainly used to protect the connecting cables of the axial flow pump body 2. When the cable of the axial flow pump body 2 passes through the inside of the outlet pipe 5 and is sealed, it has the effect of fixing and protecting, avoiding damage and pollution caused by pulling the cable.

[0025] The wiring diagram of the axial flow pump body 2 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the axial flow pump body 2 are no longer explained in detail.

[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
