Description

Technical Field

[0001] The invention relates to the technical field of water pumps, and in particular to an anti-clogging intelligent submersible pump. Background Art

[0002] A submersible pump is a pump designed to work completely immersed in water. It is suitable for pumping water from wells, underground, lakes or rivers. It is also commonly used in sewage drainage systems. Submersible pumps may become blocked. The main reasons include solid matter entering the pump body, fibers entangled in the impeller, and the pumped material is not suitable for the design conditions of the pump. It is very important to prevent submersible pumps from being blocked because blockage will reduce pump efficiency, increase energy consumption, shorten the service life of the pump and increase maintenance costs.

[0003] In the Chinese patent publication number CN117780656B, an anti-clogging intelligent submersible pump is disclosed. The weeds between the two filter covers are continuously cut by a rotating first cutter, so that the weeds between the two filter covers are broken. The broken weeds will enter the submersible pump through the inner filter cover, and then be directly discharged with the water discharged from the submersible pump, thereby preventing the weeds from entering the submersible pump and causing the propeller blades to get stuck. In the Chinese patent publication number CN113294350B, an adjustable anti-clogging full-lift submersible pump is disclosed. The hollow cylinder is driven to rotate by the rotation of the clamp, and the telescopic rod is driven to rotate by the rotation of the hollow cylinder. When the telescopic rod rotates, centrifugal force is generated and the elastic deformation of the reset spring is extended, so that the cleaning brush can fit the inner wall of the mesh cover, so that the inner wall of the mesh cover can be cleaned by the rotation of the cleaning brush to remove impurities on the surface of the mesh cover and prevent impurities from clogging the mesh cover. However, the above technical solution still has the following defects:

[0004] 1. It is inevitable that there will be some small branches and other debris during the pumping process of the submersible pump. After the branches and debris pass through the filter cover and are cut off, the broken branches are still likely to remain in the filter holes of the filter cover, causing the filter cover to be blocked;

[0005] 2. Submersible pumps are easily affected by the silt and sand on the bottom of the water during the pumping process. If tools such as pads or brackets are placed on the bottom of the water for assistance during use, it will not only be inconvenient to operate, but also when the water is deep, manual auxiliary installation is prone to safety hazards.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figure 1 , Figure 5 and Figure 8 As shown, the present invention is an anti-clogging intelligent submersible pump, including a pump body 3, a filter cover 4, a base 5 and an impeller 6. The filter cover 4 is located between the pump body 3 and the base 5, and the impeller 6 is located in the filter cover 4. The filter cover 4 is rotatably connected to the base 5. The impeller 6 is connected to the motor output end in the pump body 3 through a rotating shaft 8 to facilitate driving the impeller 6 to rotate. A plurality of linkage columns 9 connected to the filter cover 4 are installed on the side wall of the rotating shaft 8 to facilitate driving the filter cover 4 to rotate when the impeller 6 rotates. An annular groove 10 for the filter cover 4 to rotate is provided on the top of the base 5 to improve the rotation stability of the filter cover 4.

[0035] It should be noted that, in this embodiment, a water outlet 31 is installed at the water outlet end of the pump body 3, and a flow sensor (not shown in the figure) for monitoring the water outlet flow is installed in the water outlet 31. The flow sensor is electrically connected to a controller (not shown in the figure) in the pump body 3.

[0036] like Figure 1-5 As shown, an internal cleaning mechanism 1 located in the filter cover 4 is installed on the top of the base 5, and the internal cleaning mechanism 1 is used to clean out the blockage in the filter hole of the filter cover 4. A buoyancy mechanism 2 for supporting its weight is provided on the outer side of the pump body 3;

[0037] The buoyancy mechanism 2 includes a float 21, a connecting arm 23 with a self-locking component 22, a support guide frame 24 and a gravity sensing component 25. Multiple floats 21 are circumferentially distributed on the outer wall of the pump body 3. The pump body 3 is slidably connected to the support guide frame 24 through the connecting arm 23. The gravity sensing component 25 is installed at the bottom of the base 5. The gravity sensing component 25 is linked with the self-locking component 22, and the self-locking component 22 is used to lock the position of the connecting arm 23 after being started.

[0038] It should be noted that when in use, the pump body 3 is lifted up by the buoyancy generated by the multiple floats 21 in the water. The buoyancy generated by the multiple floats 21 immersed in the water is greater than the gravity of the pump body 3, but less than the total gravity of the pump body 3 and the support guide frame 24, so that the filter cover 4 will not contact the bottom of the water when it is in the water, thereby avoiding being affected by the mud and silt on the bottom of the water. After the water level gradually decreases, the pump body 3 adaptively descends along the support guide frame 24 through the connecting arm 23, and the gravity sensing component 25 is used to facilitate the filter cover 4 to generate an electrical signal to the controller in the pump body 3 when it is about to contact the mud or silt on the bottom of the water. The controller receiving the electrical signal is a mature and well-known technology, which will not be elaborated here. The controller triggers the self-locking component 22, thereby locking the position of the pump body 3, so that it will no longer touch the mud or silt on the bottom of the water as the water level drops;

[0039] The internal cleaning mechanism 1 can not only cut off the blockages that pass through the filter holes of the filter cover, but also push out the cut blockages when they block the filter holes, which is beneficial to improving the anti-blocking effect of the submersible pump.

[0040] like Figure 2-3 As shown, the support guide frame 24 includes an upper ring body 241, a lower ring body 242, a connecting column 243, a guide column 244, a rack 245 and a pin 246, a plurality of connecting columns 243 are circumferentially connected between the upper ring body 241 and the lower ring body 242, a plurality of pins 246 are circumferentially connected to the bottom of the lower ring body 242, a plurality of guide columns 244 are circumferentially connected to the top of the upper ring body 241, and a strip groove is provided on one side of the guide column 244 close to the pump body 3, and the rack 245 is installed in the strip groove.

[0041] It should be noted that, in the present embodiment, the number of guide columns 244 is three, but not limited to three. Several connecting columns 243 connect the upper ring body 241 and the lower ring body 242 together to form a stable base, which is conveniently inserted into the soil at the bottom of the water with several pins 246, so that the pump body 3 can only be lifted and lowered along the guide columns 244, thereby effectively improving the stability. The rack 245 is used to cooperate with the self-locking component 22 to lock the position of the pump body 3 as needed, so as to prevent the pump body 3 from touching the mud and silt at the bottom of the water as the water level continues to drop.

[0042] like Figure 2 and Figure 4 As shown, the gravity sensing assembly 25 includes a tension sensor 251 , a suspension rope 252 and a counterweight 253 . The tension sensor 251 is embedded and installed at the bottom of the base 5 , and the counterweight 253 is connected to the tension sensor 251 through the suspension rope 252 .

[0043] It should be noted that the tension sensor 251 is electrically connected to the controller in the pump body 3, and the counterweight 253 applies a downward pulling force to the tension sensor 251 through the pull rope 252. When the pump body 3 adaptively descends with the water level, the counterweight 253 will first come into contact with the mud and silt on the bottom of the water, thereby causing the tension value applied to the tension sensor 251 to decrease. At this time, the tension sensor 251 sends a signal to the controller in the pump body 3, thereby triggering the self-locking component 22 to lock the position of the pump body 3.

[0044] like Figure 2 and Figure 4 As shown, the connecting arm 23 includes a guide sleeve 231 , a crossbeam 232 and a cavity 233 . The guide sleeve 231 is slidably sleeved with the guide column 244 . The crossbeam 232 is connected between the guide sleeve 231 and the pump body 3 . The cavity 233 is opened in the crossbeam 232 .

[0045] It should be noted that the guide sleeve 231 and the crossbeam 232 facilitate the pump body 3 to adaptively descend with the water level. It can not only drive the guide sleeve 231 to slide stably along the guide column 244, but also facilitate limiting the position of the pump body 3 so that it will not shake in the water.

[0046] like Figure 2-4 As shown, the self-locking assembly 22 includes a tooth block 221 and a driving member 222 located in the cavity 233. The driving member 222 is used to drive the tooth block 221 to slide along the cavity 233. A sliding opening for the tooth block 221 to pass through is opened on one side of the guide sleeve 231 close to the crossbeam 232.

[0047] It should be noted that, in the present embodiment, the driving member 222 includes an electric push rod electrically connected to the controller in the pump body 3, but is not limited to the electric push rod. The driving member 222 is started by controlling the controller to facilitate pushing the tooth block 221 to slide along the cavity 233 until the tooth block 221 engages with the rack 245 in the strip groove of the guide column 244, thereby locking the position of the connecting arm 23, so that the pump body 3 will no longer slide down as the water level drops.

[0048] like Figure 1 and 5 -7, the internal cleaning mechanism 1 includes a shell 11, an internal cutter 12, a movable block 13, a magnetic resetting mechanism 14 and a pushing assembly 15. The shell 11 is arranged close to the inner circle of the filter cover 4, and the bottom end of the shell 11 is connected to the top of the base 5. The internal cutter 12 is connected to one side of the shell 11, and the internal cutter 12 is used to cut the blockages that pass through the filter holes of the filter cover 4. The movable block 13 is slidably installed in the shell 11, and the pushing assembly 15 is installed on the side of the movable block 13 close to the filter cover 4, and the pushing assembly 15 is used to push out the blockages in the filter holes of the filter cover 4. The magnetic resetting mechanism 14 is installed in the shell 11, and the magnetic resetting mechanism 14 is used to drive the movable block 13 to slide in the shell 11.

[0049] It should be noted that, when in use, the rotatable filter cover 4 and the inner cutter 12 rotate relative to each other, which is convenient for cutting off the blockage extending into the filter cover 4. When blockages remain in the filter holes of the filter cover 4, the flow rate of the water outlet 31 will be reduced. It should be noted that because there are many filter holes on the filter cover 4, when a few filter holes are blocked, it will not have a significant impact on the water pumping volume. Only when the flow rate of the water outlet 31 is lower than the set threshold, the controller in the pump body 3 will trigger the magnetic reset mechanism 14, so that it cooperates with the push assembly 15 to clean up the blockages in all the filter holes of the filter cover 4.

[0050] like Figure 6-7 As shown, the magnetic resetting mechanism 14 includes an electromagnet 141, a connecting frame 142, an iron plate 143 and a resetting spring 144. The electromagnet 141 is fixedly installed in the housing 11, and the electromagnet 141 is penetrated by a through hole for the connecting frame 142 to pass through. One end of the connecting frame 142 is connected to the movable block 13, and the iron plate 143 is embedded and installed on one side of the connecting frame 142 corresponding to the electromagnet 141. The resetting spring 144 is installed between the electromagnet 141 and the connecting frame 142.

[0051] It should be noted that when the controller in the pump body 3 triggers the magnetic reset mechanism 14, the power supply of the electromagnet 141 will be turned on to make it magnetic, so that the electromagnet 141 can attract the iron plate 143 on the connecting frame 142, so that the connecting frame 142 drives the movable block 13 to slide along the shell 11 and stretch the reset spring 144. In order to prevent the electromagnet 141 from generating an adsorption force on the reset spring 144, in this embodiment, the reset spring 144 is made of non-ferromagnetic material. After the movable block 13 slides, the push assembly 15 extends from the shell 11, thereby facilitating the cleaning of the blockage in the filter hole of the filter cover 4.

[0052] like Figure 6-7 As shown, the push assembly 15 includes a push pin 151 and a compression spring 152, multiple push pins 151 are distributed along the height direction of the movable block 13, and multiple push pins 151 correspond to multiple filter holes of the filter cover 4 along the height direction, and a receiving groove for plugging the push pin 151 is opened on one side of the movable block 13, one end of the compression spring 152 is connected to the bottom of the receiving groove, and the other end of the compression spring 152 is connected to the push pin 151.

[0053] It should be noted that, in the present embodiment, a plurality of groups of filter holes equidistantly distributed in a circular shape from top to bottom are arranged on the filter cover 4, and the number of filter holes of the filter cover 4 along the height direction is specifically three (not limited to three), and the number of the ejector pins 151 arranged on the movable block 13 is also three, and they correspond one to one to the three filter holes in the height direction of the filter cover 4. After the movable block 13 drives the pushing assembly 15 to extend out of the shell 11, the ejector pin 151 will contact the inner circle of the filter cover 4 and be compressed into the receiving groove, so that the compression spring 152 is in a force storage state. When the filter cover 4 rotates to drive the filter hole to correspond to the ejector pin 151, the force-accumulated compression spring 152 resets and pushes into the filter hole to pound out the blockage. As the filter cover 4 continues to rotate, the ejector pin 151 with a spherical end will slide into the receiving groove under force until it pops out when corresponding to the subsequent filter hole. This process is repeated to clear all the filter holes.

[0054] like Fig. 9 As shown, in order to facilitate the cleaning of the outside of the filter cover 4, the present embodiment also includes an external cleaning mechanism 7, which includes a column 71, an external cutting knife 72 and an arc rod 73, an external convex thorn 74 and an internal convex thorn 75. A plurality of columns 71 are circumferentially distributed on the top of the base 5, the top of the column 71 is connected to the bottom of the pump body 3, and the column 71 is located on the outside of the filter cover 4, the external cutting knife 72 is installed on the side of the column 71 close to the filter cover 4, a plurality of arc rods 73 are circumferentially connected between two adjacent columns 71, and a plurality of external convex thorns 74 and a plurality of internal convex thorns 75 are respectively installed on both sides of the arc rod 73.

[0055] It should be noted that the column 71 cooperates with multiple arc rods 73 to facilitate the protection of the filter cover 4, which can prevent larger garbage in the water from approaching the filter cover 4. The external convex thorns 74 are used to facilitate the retention of plastic bags close to the filter cover 4. During the rotation of the filter cover 4, the internal convex thorns 75 are used to facilitate the cleaning of plastic bags adsorbed on the filter cover 4. The external cutting knife 72 is not only convenient for cutting off the blockage stuck on the filter cover 4, but also convenient for cleaning the debris attached to the outer surface of the filter cover 4, which is conducive to further improving the anti-blocking effect.

[0056] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
