DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figures 1 to 8 , the present invention provides a technical solution:

[0030] An integrated prefabricated pump station automatic cleaning and flushing device includes a wellbore 1, which is hoisted and fixed on a concrete base plate 9, and the concrete base plate 9 is pre-buried in the pumping well of the prefabricated pump station. A limited support base 8 is provided at the upper end of the concrete base plate 9, and a lifting ring 6 for hoisting connection is provided on the upper outer wall of the wellbore 1.

[0031] The lifting ring 6 is provided to facilitate the lifting and installation of the shaft 1. During the installation process, a concrete base plate 9 is first pre-buried in the well hole to enhance the stability of the bottom installation of the prefabricated pump station, and the limiting support base 8 is used to achieve the limiting and fixed installation of the shaft 1.

[0032] A maintenance platform 2 is provided in the inner cavity of the wellbore 1, and the inner cavity of the wellbore 1 is divided into a water inlet cavity 10 and a control cavity 11 through the maintenance platform 2. A grid cleaning machine 5 and a submersible pump 7 are provided in the water inlet cavity 10. The grid cleaning machine 5 is connected to a water inlet pipe 12 of the pumping well hole. A valve pipe 3 is provided in the control cavity 11. A control panel 4 is provided at the upper end of the wellbore 1. The submersible pump 7, the switching valve 14, the driving component 38 of the grid cleaning machine 5, the valve pipe 3 and the motor 34 are all electrically connected to the control panel 4.

[0033] By providing a maintenance platform 2 and a valve pipe 3 and a control panel 4 located in the control cavity 11, convenient control and adjustment of the equipment and pipes in the prefabricated pump station can be achieved. By providing a cleaning grid machine 5 at the port of the water inlet pipe 12, impurities in the incoming water flow can be fully crushed to avoid blockage caused by excessive impurities.

[0034] A transversely installed bottom cross beam 18 is provided at the bottom of the water inlet cavity 10, and the submersible pump 7 is fixedly installed at one end of the bottom cross beam 18. A water inlet port 19 is provided on one side of the submersible pump 7. A pair of fan blades 22 driven by a motor 34 are telescopically provided on one side of the submersible pump 7 close to the water inlet port 19, and the pair of fan blades 22 are respectively located on the front and rear sides of the bottom cross beam 18.

[0035] By setting the bottom cross beam 18, the submersible pump 7 can be installed in the air, and the fan blades 22 driven by the motor 34 can be used to fully stir, break up and mix the water flow entering the water inlet port 19, so as to prevent the entry of lumps of sludge and impurities, which would cause blockage inside the submersible pump 7. Through the stirring of the fan blades 22, the falling and deposited sludge is in an upward and mixed state, which reduces the deposition speed and improves the drainage efficiency of the submersible pump 7.

[0036] An inner flow channel 27 is provided in the fan blade 22, a drainage pipe 15 connected to the output end of the submersible pump 7 and discharging water to the outside of the wellbore 1 is provided in the valve pipe 3, an input pipe of the external water tank is provided in the valve pipe 3, and the input pipes are respectively connected to the first cleaning pipe 13 and the second cleaning pipe 16, an ear seat 17 is provided on the inner wall of the water inlet cavity 10, and the cleaning grid machine 5 is fixedly installed on the ear seat 17, and a switching valve 14 is provided at the input end of the cleaning grid machine 5, and the input end of the switching valve 14 is provided with two ports which are respectively connected to the water inlet pipe 12 and the first cleaning pipe 13, the second cleaning pipe 16 is connected to the inner flow channel 27, and the first cleaning pipe 13 is connected to the cleaning grid machine 5.

[0037] By reversely feeding water into the grid cleaning machine 5 and the inner flow channel 27, the purpose of automatically flushing the water inlet cavity 10 is achieved.

[0038] Working principle: First, the fan blades 22 driven by the motor 34 are used to fully stir, break up and mix the water flow entering the water inlet port 19 to prevent the entry of lumps of sludge and impurities, which may cause blockage inside the submersible pump 7. The fan blades 22 stir the falling and deposited sludge to be in an upward and mixed state, which reduces the deposition speed and improves the drainage efficiency of the submersible pump 7.

[0039] When the water inlet cavity 10 needs to be cleaned, the switching valve 14 is used to close the water inlet pipe 12. At this time, with the continuous operation of the submersible pump 7, the water level in the water inlet cavity 10 gradually decreases. When the water level drops to the lower end of the cleaning grid machine 5, the first cleaning pipe 13 is used to feed water into the cleaning grid machine 5 to achieve the purpose of flushing and cleaning the grid machine 5. When the water level drops to the position of the bottom cross beam 18, the valve pipe 3 is used to control the water to flow into the second cleaning pipe 16. By feeding water into the fan blades 22, the water flow is centrifugally thrown out during the rotation of the fan blades 22. The thrown water flow impacts the inner wall of the lower end of the water inlet cavity 10, thereby flushing the deposited and adhered silt, and stirring and breaking it up under the rotation of the fan blades 22, so that the silt is mixed in the water flow and discharged by the submersible pump 7. As the fan blades 22 are driven to extend and retract laterally along the bottom cross beam 18, the bottom of the water inlet cavity 10 is fully cleaned.

[0040] Embodiment 2: On the basis of embodiment 1, a plurality of groups of mutually meshing crushing rollers 40 are arranged in the middle of the inner cavity of the cleaning grid machine 5, the output end of the switching valve 14 is connected to the upper end of the inner cavity surrounded by the plurality of groups of crushing rollers 40, the upper end of the cleaning grid machine 5 is provided with a driving assembly 38 for driving the plurality of groups of crushing rollers 40 to rotate relative to each other, a plurality of groups of grids 39 distributed in a circular array are arranged on the outer side of the plurality of groups of crushing rollers 40, the gap width between the grids 39 is smaller than the gap width between the crushing rollers 40, and a plurality of groups of water outlets 41 connected to the water inlet cavity 10 are arranged on the outer wall of the cleaning grid machine 5.

[0041] By providing the crushing roller 40, the impurities in the incoming water flow are crushed and processed, so that the impurities are turned into small particles, which are mixed in the water flow for easy discharge, and blockage caused by excessive volume is avoided.

[0042] Embodiment 3: On the basis of Embodiment 2, a pair of sleeves 21 corresponding to the fan blades 22 are provided on the outer wall of the submersible pump 7, a sleeve 31 is slidably inserted in the inner cavity of the sleeve 21, an end block is provided at the other end of the sleeve 31, the fan blade 22 is rotatably mounted on the end block, a cavity connected to the internal flow channel 27 is provided in the end block, the other end of the cavity is connected to the inner cavity of the sleeve 21, and a sealing sleeve 32 for sealing is provided at the port position on one side where the sleeve 21 and the sleeve 31 are sleeved.

[0043] The blades 22 are installed in a telescopic and sliding manner by plugging and fitting the sleeve 21 and the inserting tube 31 , and the inserting tube 31 is sealed and slidably sleeved in the sleeve 21 by means of the sealing sleeve 32 .

[0044] A connecting port 20 is provided on the bottom cross beam 18, one end of the connecting port 20 is connected to the second cleaning pipe 16, and the other end of the connecting port 20 is connected to the inner cavity of the sleeve 21 through a connecting pipe 33. The inserts 31 on a pair of fan blades 22 are connected by a sliding beam 25. A through transverse groove 23 penetrating front and back is provided on the bottom cross beam 18, and the middle section of the sliding beam 25 extends along the through transverse groove 23. A vertically arranged limiting slide groove 24 is provided in the middle of the through transverse groove 23, and a sliding block 26 is provided on the sliding beam 25, and the sliding block 26 slides along the limiting slide groove 24.

[0045] By providing a connecting port 20 and a connecting pipe 33, the second cleaning pipe 16 is connected to the inner flow channel 27, and the connection between the sleeve 21 and the insert pipe 31 is utilized to always keep the pipe connected during the extension and sliding process of the fan blades 22. The sliding beam 25 is utilized to realize the synchronous movement of a pair of fan blades 22. The position of the sliding beam 25 is limited by the cooperation of the limiting slide groove 24 and the through-transverse groove 23 to maintain its smooth sliding.

[0046] A folding bag 30 is disposed through the transverse groove 23 , one end of the folding bag 30 is connected to the connecting port 20 , and the other end of the folding bag 30 is fixed on the sliding beam 25 .

[0047] By setting up the folding bag 30, during the water intake process, as the water pressure increases, the folding bag 30 expands, thereby driving the sliding beam 25 to slide, and realizing the synchronous telescopic drive of a pair of fan blades 22. Therefore, by utilizing the water intake of the second cleaning pipe 16, the fan blades 22 can be centrifugally cleaned by water throwing and horizontally telescopically driven, and the fan blades 22 can be driven to rotate in coordination with the motor 34, so as to fully flush the inner wall of the bottom of the water intake cavity 10.

[0048] Embodiment 4: On the basis of Embodiment 3, during the rotation of the fan blade 22, the insert tube 31 will be caused to rotate. Rings 29 are provided at both ends of the sliding beam 25. The rings 29 are sleeved on the end blocks at the ends of the insert tube 31. Both sides of the rings 29 are fixed by a stop rod assembly 28 inserted on the end blocks. The stop rod assembly 28 includes a pin rod 36, a rotating block 35 and a limiting nut 37. The pin rod 36 slides through the end block. Both ends of the pin rod 36 are fixed by limiting nuts 37. A rotating block 35 for bearing rotation is provided at the end of the pin rod 36. The arc outer wall of the rotating block 35 rotates to fit the side wall of the ring 29.

[0049] By setting the ring 29, the end block at the end of the tube 31 and the sliding beam 25 are rotatably connected, and the stop rod assembly 28 is used to limit the lateral position of the ring 29, so that the sliding beam 25 can drive the tube 31 to slide laterally. The rotation of the tube 31 caused by the fan blades 22 causes friction to be generated between the stop rod assembly 28 and the ring 29. The rotating block 35 installed by bearing rotation fits with the ring 29, thereby generating relative rotation and reducing friction.
