Description

Technical Field

[0001] The utility model relates to the technical field of axial flow pumps, in particular to an anti-blocking axial flow pump. Background Art

[0002] Axial flow pumps are often used in paddy field irrigation, urban sewage treatment and other fields. During the use of axial flow pumps, the filter plate at the bottom horn water inlet is often blocked by some leaves, weeds, waste paper and other debris, which greatly reduces the water flow rate of the axial flow pump and reduces the working efficiency.

[0003] Currently, people have to manually enter the water through the inspection hole to remove the debris blocking the filter plate, which is time-consuming and laborious. In addition, it is easy to clean the large impurities blocking the filter plate, but it is difficult to remove the small impurities blocking the filter plate. The filter plate often needs to be removed for cleaning, but after removal, the axial flow pump will be unusable for a short period of time. For this reason, we propose an anti-blocking axial flow pump. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] As mentioned in the background technology, in the prior art, the debris that blocks the filter plate is removed manually through the inspection hole underwater, which is time-consuming and laborious. Moreover, it is convenient to clean the large-volume impurities that block the filter plate, but it is difficult to remove the small-volume impurities that block the filter plate. The filter plate often needs to be removed for cleaning, but after removal, the axial flow pump will be unusable for a short period of time. The utility model proposes an anti-blocking axial flow pump.

[0021] Example 1

[0022] Reference Figure 1 to Figure 2 , an anti-blocking axial flow pump, comprising an axial flow pump 1 and a wall 3, wherein a mounting plate 2 connected to the wall 3 is arranged on the outer wall of the axial flow pump 1;

[0023] An installation box 5 is provided outside the bottom of the axial flow pump 1, and the bottom of the axial flow pump 1 is located in the installation box 5 so that the water in the installation box 5 can be pumped away when pumping water;

[0024] In order to allow water to enter the installation box 5 without entering debris, filter plates 6 are penetrated on both sides of the bottom of the installation box 5. In order to use only one filter plate 6 on both sides at a time, a fixing box 7 is provided on both sides of the installation box 5, and an electric telescopic rod 8 powered and controlled by the existing technology is provided in the fixing box 7. A baffle 9 is provided on the output end of the electric telescopic rod 8, which is fitted and connected to the bottom of the installation box 5. One side of the baffle 9 is fitted and connected to the bottom of the corresponding filter plate 6, so that one of the filter plates 6 is not blocked by the baffle, and the debris in the water can be filtered, so that the shaft The axial flow pump 1 can filter the impurities in the water, and then draw the water into the axial flow pump 1 through the installation box 5 to pump water. Then, when the filter plate 6 is blocked, the electric telescopic rods 8 on both sides are started at the same time, so that the baffle 9 corresponding to the blocked filter plate 6 moves to block the filter plate 6, and the baffle 9 can be moved to the bottom of the filter plate 6 to push away the impurities attached to the bottom of the filter plate 6. After the baffle 9 corresponding to the unblocked filter plate 6 moves, it no longer blocks the filter plate 6, so that one filter plate 6 can be used normally, thereby avoiding the anti-blocking of the axial flow pump 1 and ensuring the continuous use of the axial flow pump 1.

[0025] The filter plates 6 on both sides are provided with fixing components, and the fixing components on both sides are detachably connected to the mounting plate 2 .

[0026] The wall 3 is provided with a through hole 4 below the mounting plate 2 so that the mounting box 5 and the fixing box 7 can be moved through the through hole 4 .

[0027] The fixing assembly includes a connecting rod 10 arranged on the top of the filter plate 6. The connecting rod 10 does not completely block the filter plate 6 and does not affect the passage of water at the filter plate 6. A connecting plate 11 is arranged on the top of the connecting rod 10. A fixing hole 12 with a radius larger than the filter plate 6 is opened on the top of the installation box 5, so that the filter plate 6 can easily pass through the fixing hole 12, and the connecting plate 11 covers the top of the fixing hole 12 for supporting the connecting plate 11. A valve is arranged in the fixing hole 12, and the valve is remotely controlled. When the filter plate 6 is not removed, the valve is in a normally open state. When the filter plate 6 leaves the installation box 5, the valve is immediately closed. A fixing rod 16 located in the through hole 4 is arranged on the top of the connecting plate 11, and a cover plate 14 is arranged on the top of the fixing rod 16.

[0028] The mounting plate 2 is provided with a mounting hole 13 with a radius larger than that of the connecting plate 11 , so that the connecting plate 11 can easily pass through the mounting hole 13 . The cover plate 14 covers the top of the mounting hole 13 to support the cover plate 14 .

[0029] Example 2

[0030] Reference Figure 1 to Figure 2 The cover plate 14 is provided with bolts 15 connected with the mounting plate 2 for fixing the cover plate 14 .

[0031] When the clogged filter plate 6 is blocked by the baffle 9, the corresponding bolts 15 are removed, and the cover plate 14 can be moved upward, and the connecting plate 11 can be driven to move by the fixing rod 16, so that the connecting rod 10 drives the clogged filter plate 6 to quickly pass through the fixing hole 12, and finally take it out through the through hole 4 and the installation hole 13. After passing through the fixing hole 12, the valve at the fixing hole 12 is closed, so that no water enters the fixing hole 12, and the debris brought in by the water that briefly enters when the filter plate 6 passes through the fixing hole 12 has little effect on the axial flow pump 1, and can be processed separately later.

[0032] The rest of the structure is the same as that of Example 1.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
