Description

Technical Field

[0001] The utility model relates to the field of pumps, in particular to a combined vertical submerged long-axis pump for preventing liquid seepage. Background Art

[0002] Vertical long-axis pumps are commonly used in water companies, sewage treatment plants, power plants, steel mills and other enterprises. Sometimes they are also commonly used in municipal water supply and drainage and flood control and drainage projects. They are a type of centrifugal pump and require stronger stability during operation to adapt to the suction of clean water, rainwater, corrosive industrial wastewater, seawater and other liquids. A filter cover is usually set on the lower side of the pump body to filter impurities in the liquid. However, when the long-axis pump is used for flood control and drainage, the gravel in the pumped sewage will be stuck in the filter port of the filter cover, causing serious blockage of the filter port and reducing the suction efficiency of the pump body. Utility Model Content

[0003] In order to overcome the disadvantage that when the crushed stones in the pumped liquid are stuck in the filter port of the filter cover, the filter port will be seriously blocked and the pumping efficiency of the pump body will be reduced, the utility model provides a combined vertical submersible long-axis pump for preventing liquid from being seen.

[0005] Preferably, it also includes a rotating rod, a rope, a sliding frame, a scraper block and a spring body; the fixed end of the spring rod is fixedly connected to two rotating rods distributed up and down, and a torsion spring is provided between the rotating rod and the fixed end of the spring rod; the telescopic end of the spring rod is fixedly connected to two sliding frames; the push block is provided with a sliding groove; the scraper block is slidably connected in the sliding groove; each rotating rod is wrapped with a rope, and the rope passes around the corresponding sliding frame and passes through the push block and then is fixedly connected to the scraper block; the two scraper blocks are connected by the spring body.

[0006] Preferably, the push block is cylindrical.

[0007] Preferably, the upper side of the scraper block is conical.

[0008] Preferably, a scraper strip is also included; a plurality of scrapers are fixedly connected to the conical surface of the scraper block.

[0011] The beneficial effects of the utility model are as follows: the spring rod drives the push block to rotate through the connecting rod, so that the push block contacts the inclined surface of the wedge-shaped linkage block to squeeze the spring rod, and the spring rod is compressed. When the push block continues to rotate until it is separated from the linkage block, the push block pops out to the filter port under the elastic force of the spring rod, thereby pushing out the crushed stones stuck at the filter port to prevent the crushed stones from blocking the filter port.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Example

[0022] A combined vertical submersible long-axis pump for preventing seepage, such as Figure 1-6 As shown, it includes a tube body 1, a liquid outlet pipe 2, a filter cover 3, a first motor 4, a rotating shaft 5 and an impeller 6; the tube body 1 is connected to the liquid outlet pipe 2; the filter cover 3 is detachably provided on the lower side of the tube body 1; the filter cover 3 is provided with a plurality of filter ports 3a distributed in an annular manner; the tube body 1 is bolted to the first motor 4; the rotating shaft 5 is rotatably connected in the tube body 1, and the rotating shaft 5 is fixedly connected to the output shaft of the first motor 4; the rotating shaft 5 is fixedly connected to a plurality of impellers 6;

[0023] It also includes a mounting plate 8, a cover shell 9, a second motor 10, a connecting rod 11, a linkage block 101, a spring rod 102 and a push block 103; the mounting plate 8 is fixedly connected to the inner side of the filter cover 3; the mounting plate 8 is fixedly connected to the cover shell 9; the mounting plate 8 is bolted to the second motor 10, and the second motor 10 is located in the cover shell 9; the mounting plate 8 is rotatably connected to the connecting rod 11, and the connecting rod 11 is fixedly connected to the output shaft of the second motor 10; a plurality of wedge-shaped linkage blocks 101 are fixedly connected to the inner side of the filter cover 3, and the linkage blocks 101 are spaced apart from the filter port 3a; a spring rod 102 is fixedly connected; a push block 103 is fixedly connected to the telescopic end of the spring rod 102.

[0024] It also includes a rotating rod 104, a rope 105, a sliding frame 106, a scraper block 107 and a spring body 108; the fixed end of the spring rod 102 is fixedly connected to two rotating rods 104 distributed up and down, and a torsion spring is provided between the rotating rod 104 and the fixed end of the spring rod 102; the telescopic end of the spring rod 102 is fixedly connected to two sliding frames 106; the push block 103 is provided with a sliding groove 103a; the scraper block 107 is slidably connected in the sliding groove 103a; each rotating rod 104 is wrapped with a rope 105, and the rope 105 bypasses the corresponding sliding frame 106 and passes through the push block 103 and is fixedly connected to the scraper block 107; the two scraper blocks 107 are connected through the spring body 108.

[0025] The push block 103 is cylindrical.

[0026] The upper side of the scraper block 107 is tapered, thereby reducing the resistance between the scraper block 107 and the linkage block 101 and facilitating the scraper block 107 to pass through the linkage block 101 .

[0027] It also includes scraper strips 109 ; a plurality of scraper strips 109 are fixedly connected to the conical surface of the scraper block 107 .

[0028] The scraper strip 109 is distributed on the side of the scraper block 107 away from the inclined surface of the linkage block 101 to prevent the scraper block 107 from being hindered from moving due to large friction between the scraper strip 109 and the linkage block 101 when the scraper block 107 rotates through the linkage block 101 .

[0029] It also includes a sealing ring 7; each flange connection of the pipe body 1 has two sealing rings 7 fixedly connected.

[0030] The working steps of the above embodiment are: when in use, the combined vertical submersible long-axis pump of the anti-seepage liquid is installed on the external mounting frame, the lower half of the tube body 1 is placed in the liquid to be pumped, and the external delivery pipe is connected to the liquid outlet pipe 2. Then, the first motor 4 is controlled to start, and the output shaft of the first motor 4 drives the impeller 6 to rotate clockwise from the top to the bottom, so that the rotating impeller 6 generates a strong suction force on the filter cover 3, and the liquid is sucked into the tube body 1 through the filter cover 3, and finally transported from the liquid outlet pipe 2 to the external delivery pipe. After the suction is completed, the filter cover 3 is disassembled for cleaning.

[0031] When pumping liquid, the second motor 10 is controlled to start, and the connecting rod 11 is driven to rotate by the output shaft of the second motor 10. The connecting rod 11 causes the spring rod 102 to drive the push block 103 to rotate, so that the push block 103 contacts the inclined surface of the wedge-shaped linkage block 101 of the linkage block 101 and squeezes the spring rod 102. The spring rod 102 is compressed, and when the push block 103 continues to rotate until it is separated from the linkage block 101, the push block 103 is ejected to the filter port 3a under the elastic force of the spring rod 102, thereby pushing out the gravel stuck at the filter port 3a to prevent the gravel from blocking the filter port 3a. Since the push block 103 is arranged in a cylindrical shape, the resistance between the push block 103 and the linkage block 101 is reduced, which makes it easy for the push block 103 to slide over the linkage block 101. When the pumped liquid is sucked into the tube body 1 through the filter cover 3, the cover shell 9 is flushed, thereby dissipating the heat of the motor in the cover shell 9.

[0032] When the long-axis pump is used to pump sewage for flood control and drainage, there will be strips of cloth, branches and other strips of debris in the sewage. Driven by the water flow, the strips of debris are in a vertical state with the filter port 3a and attached to the filter port 3a. At this time, the push block 103 cannot remove the strips of debris attached to the filter port 3a, thereby affecting the suction efficiency. When the push block 103 contacts the linkage block 101, the spring rod 102 is compressed, and the distance between the push block 103 and the rotating rod 104 is shortened, so that the rotating rod 104 releases the rope 105 under the restoring force of the torsion spring, so that the two scraping blocks 107 slide towards each other in the slide groove 103a under the rebound force of the spring body 108, and the two scraping blocks 107 stretch the rope 105 to keep the rope 105 straight until the two scraping blocks 107 are close to each other and are located in the middle of the slide groove 103a.

[0033] When the push block 103 continues to rotate and disengage from the linkage block 101, the push block 103 pops out under the elastic force of the spring rod 102, and the distance between the push block 103 and the rotating rod 104 becomes longer. The rope 105 pulls the scraper block 107, so that the two scraper blocks 107 move away from each other at the two ends of the slide groove 103a, and the spring body 108 is stretched, so that the rope 105 pulls the rotating rod 104 to rotate, and the torsion spring is compressed. Then, when the two scraper blocks 107 slide in the slide groove 103a and move away from each other, the strip-shaped debris attached to the filter port 3a is scraped to the upper and lower sides of the filter port 3a, thereby increasing the efficiency of liquid passing through the filter port 3a. Since the scraper block 107 is conically arranged, the friction between the scraper block 107 and the debris is small, which affects the scraping of the debris by the scraper block 107. The friction between the scraper block 107 and the strip-shaped debris is increased by the scraping strip 109, thereby improving the scraping efficiency of the scraper block 107 on the debris.

[0034] When the liquid passes through the flange connection on the pipe body 1, the upper and lower sides of the flange connection are sealed by the sealing ring 7 to prevent the liquid from leaking out of the flange connection.

[0035] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
