[0021] 3. The seawater pump casing cleaning device for the seawater pump uses the delivery pump as the power, so that the nozzle sprays the cleaning liquid to the seawater pump casing, thereby flushing the seawater pump casing. At the same time, the cleaning liquid passes through the I-shaped leakage hole on the funnel, and under the guidance of the secondary piece, the outer surface of the secondary piece is set as an arc surface, so that the fluid forms a vortex, changes the flow direction of the fluid, and then stirs the discharged cleaning liquid.

[0022] 4.

When the pressure decreases when the delivery pump sucks out the cleaning fluid, the pressure can be used in combination with the elastic force of the top pressure spring to make the blocking plate slowly approach the I-shaped leakage hole, thereby accurately controlling the outflow of the fluid.

[0042] The servo motor 71 is used to drive the rotating shaft 72 to rotate. At this time, the brush assembly 76 is driven as a whole to rotate in a circle through the moving frame 73. Under the support of the arc support column 762, the cleaning brush 763 that rotates in a circle brushes the seawater pump housing. At the same time, as the crescent block 764 is driven by the zigzag bending rod 761 to rotate, and the outer surface of the crescent block 764 is used to contact the end of the top ball 62, the crescent block 764 will be subjected to an upward jacking force, and can slide on the top of the outer surface of the rotating shaft 72 in combination with the moving frame 73, and under the guidance of the guide bar 74, the brush assembly 76 is driven by the moving frame 73 to move upward as a whole, and the elastic reset member 75 is compressed, and with the continuous rotation, the crescent block 764 is subjected to the jacking force of the top ball 62.

[0043] The second embodiment, as Figure 1-Figure 11 As shown, on the basis of the first embodiment, the agent storage tank 6 has a tank body 61 fixed at the top center position of the frame 1, a top ball 62 is fixedly connected to the inner surface of the tank body 61 and near the bottom position, an arc-shaped channel 63 is fixedly connected to the outer surface of the tank body 61, an interception filter 64 is fixedly connected to the tail end of the arc-shaped channel 63 and near the inner surface position of the tank body 61, and an inclined filter 65 is fixedly connected to the inner surface of the arc-shaped channel 63;

[0044] A drainage assembly 8 is provided at the bottom of the tank body 61, and a delivery pump 9 is fixedly connected to the bottom of the tank body 61. The liquid inlet end of the delivery pump 9 is fixed and connected to a connecting pipe 10, and the liquid outlet end of the delivery pump 9 is fixed and connected to a hose 11. The top end of the hose 11 is fixed and connected to the liquid inlet end of the nozzle 5, and the drainage assembly 8 and the connecting pipe 10 are connected.

[0045] The top balls 62 are evenly distributed on the inner surface of the tank body 61 and close to the bottom, and the arc-shaped channels 63 are evenly distributed on the outer surface of the tank body 61 .

[0046] The outer surface of the blades 68 is arranged in an arc shape, and the blades 68 are evenly distributed on the outer surface of the rotating rod 67 , and the outer surface edge of the guide plate 66 is close to the position of the blades 68 .

[0047] By immersing the seawater pump housing in the solution in the tank body 61, when the brushing component 76 is driven to rotate, not only the seawater pump housing can be brushed, but also the cleaning solution in the tank body 61 can be stirred, so that the clear and thin solution will also flow in a circular manner, so that the cleaned debris is subjected to centrifugal force and moves along the inner surface of the tank body 61, and driven by the solution fluid, the floating debris enters the arc channel 63 from the guide plate 66, and is combined with the interception filter 64 to block the floating debris, and the inclined filter 65 can prevent the backflow of the debris, thereby removing the floating debris. At the same time, under the impact of the fluid and combined with the rotation of the rotating shaft 72, the blade 68 rotates, and then the debris remaining on the inclined filter 65 is moved, thereby promoting the removal of the debris.

[0048] The third embodiment, as Figure 1-Figure 11 As shown, the drainage assembly 8 includes a funnel 81, the top of the funnel 81 is fixedly connected to the bottom of the tank body 61, the bottom of the inner surface of the funnel 81 is fixedly connected to a push spring 82, the top of the push spring 82 is fixedly connected to a regulating module 83, the top of the inner surface of the funnel 81 is fixedly connected to a conical cap 84, and the outer surface of the conical cap 84 is provided with a straight leakage hole 85.

[0049] The regulating module 83 includes a base plate 831, the bottom of which is fixedly connected to the top of the pressure spring 82, the top of the inner surface of the base plate 831 is fixedly connected to a secondary plate 832, and the top edge of the base plate 831 is fixedly connected to a sealing plate 833, which is located directly below the I-shaped leakage hole 85.

[0050] The outer surface of the secondary plate 832 is set as an arc surface, and the blocking plate 833 is set obliquely. The blocking plates 833 are evenly distributed on the top edge of the base plate 831.

[0051] The delivery pump 9 is used as a power source, and the cleaning liquid in the tank body 61 is discharged through the discharge assembly 8 and the connecting pipe 10, and the nozzle 5 is used to spray the cleaning liquid toward the seawater pump housing through the delivery of the hose 11, thereby flushing the seawater pump housing, so that the debris attached to the outer surface of the seawater pump housing is washed away.

At this time, the servo motor 71 is used to drive the rotating shaft 72 to rotate. At this time, the brushing assembly 76 is driven to rotate in a circle as a whole through the moving frame 73. Under the support of the arc support column 762, the cleaning brush 763 that rotates in a circle brushes the seawater pump housing. At the same time, as the zigzag rod 761 drives the crescent block 764 to rotate, and the crescent block 764 is used to The outer surface of the crescent block 764 contacts the end of the top ball 62. At this time, the crescent block 764 will be subjected to an upward jacking force, and can slide on the top of the outer surface of the rotating shaft 72 in combination with the moving frame 73, and under the guidance of the guide bar 74, the brush assembly 76 is driven by the moving frame 73 to move upward as a whole, and the elastic reset member 75 is compressed, and with continuous rotation, the crescent block 764 is subjected to the jacking force of the top ball 62, so that the brush assembly 76 is moved downward and reset as a whole, so that the cleaning brush 763 moves back and forth up and down, and then the seawater pump housing is quickly brushed, and the seawater pump housing is immersed in the solution in the tank body 61. When the brush assembly 76 is brought When the pump body 61 is rotated, it can not only scrub the shell of the seawater pump, but also stir the cleaning solution in the tank body 61, so that the clean and diluted solution will also flow in a circular manner, so that the cleaned debris is subjected to centrifugal force and moves along the inner surface of the tank body 61, and driven by the solution fluid, the floating debris enters the arc channel 63 from the guide plate 66, and is combined with the interception filter 64 to block the floating debris, and combined with the inclined filter 65 to prevent the debris from backflow, thereby removing the floating debris. At the same time, under the impact of the fluid and combined with the rotation of the rotating shaft 72, the blade 68 rotates, thereby removing the residue on the inclined filter. The debris on the seawater pump 65 is moved to promote the removal of the debris, and the delivery pump 9 is used as a power to discharge the cleaning liquid in the tank body 61 through the discharge assembly 8 and the connecting pipe 10, and the nozzle 5 is used to spray the cleaning liquid to the seawater pump housing through the delivery of the hose 11, so as to flush the seawater pump housing, so that the debris attached to the outer surface of the seawater pump housing is washed away, and at the same time, the cleaning liquid passes through the straight leak hole 85 on the funnel 81, and under the guidance of the secondary sheet 832, the outer surface of the secondary sheet 832 is set as an arc surface, so that the fluid forms a vortex, changes the flow direction of the fluid, and then stirs the discharged cleaning liquid.
