[0017] Further, when the first control valve moves upward to contact the second solenoid valve, the fan starts to operate. After the first control valve cancels the contact with the second solenoid valve, the fan stops operating.

[0018] The beneficial effects of the present invention: 1. The present invention enables two movable plates to slide towards or away from each other by opening an electric slider, thereby being able to grind pump casings of flood control pumps of different specifications, and the center plate is driven to move inside the pump casing by the extension and retraction of the extension plate, thereby being able to evenly grind the inside of the pump casing, and the threaded rod is driven to move left and right in the middle of the center plate by opening the electric slider, and the angles between the plurality of movable plates can be adjusted through the circular ring and the push-pull rod when the threaded rod moves, and when the movable plate rotates along the axis of the center plate, the angles between the plurality of circular arc plates can be adjusted, thereby making the plurality of circular arc plates coincide with the inclined surfaces inside the pump casing, so that when the turntable rotates, the plurality of circular arc plates rotate synchronously, thereby realizing circumferential rotation grinding of the slope surface inside the pump casing, and compared with the existing device, the present invention can grind the internal inclined surface of the pump casing, and at the same time, because the angles between the plurality of circular arc plates are easy to adjust, the slope surfaces inside the pump casings of different specifications are different, and adaptive grinding is performed on them after adjustment, thereby effectively solving the problem that the existing device cannot grind the inclined surface inside the pump casing.

[0019] 2. The present invention can continuously supply coolant to the contact surface between the arc plate and the pump casing when the arc plate is grinding the inclined surface inside the pump casing through the provision of a supply pipe. On the one hand, the heat generated in the grinding area can be cooled to avoid deformation of the casting. On the other hand, the grinding dust can be washed away, thereby extending the service life of the arc plate and also playing a lubricating role.

[0020] When the two movable plates are moved closer or farther away from each other, the circular arc plates arranged on the two movable plates can be moved inside the pump casing, so that different positions inside the pump casing can be polished. When the electric slider is opened, the two-way push rod can be rotated in the fixed part, and the driving wheel is synchronously driven to rotate during the rotation. The driving wheel drives the driven wheel to rotate through meshing, and the two-way push rod drives the rotating column to rotate in the same direction with the two driven wheels through the action of the pulley and the belt. Therefore, the pump casing fixed between the two driven wheels and the circular arc plates on both sides rotate in opposite directions. When the circular arc plates on both sides polish the slope surface inside the pump casing, the pump casing also rotates in the opposite direction with the circular arc plates, further aggravating the friction strength inside the pump casing and effectively improving the polishing efficiency. Compared with the existing polishing device, the present invention can rotate the pump casing in the opposite direction of the polishing mechanism when polishing the inside of the pump casing, thereby enhancing the polishing efficiency inside the pump casing.

[0021] 4. The present invention starts the cylinder and pushes it forward, which drives the support plate downward. When the support plate moves downward, it drives the grinding plate to be close to the outer wall of the pump casing. As the pump casing rotates, it continuously rubs against the grinding plate, so that the grinding plate rubs and grinds the pump casing. The motor is turned on to drive the cam to rotate. When the cam rotates, it intermittently squeezes the semicircular plate. After being squeezed, the semicircular plate slides on the middle rod through the middle frame, and synchronously drives the grinding plate to slide left and right on the outer edge of the pump casing, thereby achieving rotational grinding of the pump casing while the grinding plate slides left and right to grind the outer wall of the pump casing in the left and right directions. The extrusion plate is driven to move left and right on the middle rod by the extension and retraction of the electric push rod. The extrusion plate squeezes the spring when moving, so that the grinding range of the grinding plate when grinding left and right can be adjusted.

[0022] 5. When the grinding plate of the present invention moves down and contacts the outer wall of the pump casing, the built-in plate moves up in the convex groove under the reaction force of the pump casing, and the built-in plate moves up synchronously with the built-in rod. When the built-in rod moves up, the sealing plug at the end of the built-in rod cancels the blockage of the conical groove. At this time, the coolant in the liquid storage tank stays on the built-in plate along the conical groove and the vertical pipe, and finally stays on the grinding surface between the grinding plate and the pump casing through the convex groove, so as to cool down the high temperature generated during the grinding of the pump casing and realize the lubrication of the grinding plate.

[0023] 6. The present invention drives the driven wedge block to move downward synchronously when the grinding plate moves downward. When the driven wedge block moves downward, it contacts the active wedge block. The active wedge block generates a reverse force on the driven wedge block. At this time, the driven wedge block moves upward. When the driven wedge block moves upward, the first control valve and the second solenoid valve contact each other and start the suction effect on the fan in the suction pipe. At this time, the top box absorbs the dust generated during grinding into the collection box and then discharges it. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] 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.

[0027] The present invention provides a dual-purpose mobile flood-prevention pump and a pump body molding device thereof, wherein the dual-purpose mobile flood-prevention pump is a pump for conveying fluids, is convenient for flood prevention and rescue, and is a mobile flood-prevention pump for both high and low head purposes; the pump body molding device is a device for grinding a special outer shell of a circulating pump for conveying liquids, specifically, is a device for performing targeted grinding on the internal slope and outer wall of the circulating pump.

[0028] like Figure 1-Figure 14 As shown, a dual-purpose mobile flood control pump includes a pump casing 1, a middle casing 10 is detachably mounted on one side of the pump casing 1, a motor 11 is arranged on one side of the middle casing 10, a plurality of tripods 12 are arranged between the pump casing 1 and the motor 11, a bottom plate 13 is commonly mounted at the bottom ends of the tripods 12, shaft pressure covers 101 are fixedly mounted at both ends of the middle part of the middle casing 10, a pump shaft 102 is rotatably mounted between the two shaft pressure covers 101, and an impeller 103 is fixedly mounted on the outside of the pump shaft 102.

[0029] A pump body molding device for a dual-purpose mobile flood control pump, the pump body molding device includes a molding frame 2, which is convenient for placing the pump shell 1 in the molding frame 2 when the pump shell 1 is molded and polished, and two symmetrically arranged moving plates 20 are slidably installed on the lower part of the molding frame 2 through an electric slider, and a rotating column 201 is rotatably installed in the middle of the front side of the moving plate 20, and a rotating disk 202 is fixedly installed at one end of the rotating column 201, and a circumferentially arranged telescopic plate 203 is fixedly installed on the side close to the two rotating disks 202, and a central plate 204 is fixedly installed on the telescopic ends of multiple telescopic plates 203. The two movable plates 20 can be opened by the electric slider to slide towards or away from each other, so that the pump casing 1 of flood control pumps of different specifications can be polished. The center plate 204 is driven to move inside the pump casing 1 by the extension and retraction of the telescopic plate 203, so that the inside of the pump casing 1 can be polished evenly. The threaded rod 205 is driven to move left and right in the middle of the center plate 204 by the electric slider. When the threaded rod 205 moves, the angles between the multiple movable plates 206 can be adjusted through the ring and the push-pull rod 207. When the movable plate 206 rotates along the axis of the center plate 204, the angles between the multiple arc plates 208 can be adjusted, so that the multiple arc plates 208 can be matched with the inclined surface inside the pump casing 1, so that when the turntable 202 rotates, the multiple arc plates 20 8 rotates synchronously to realize circular rotation grinding of the slope inside the pump casing 1. Compared with the existing device, the present invention can grind the internal slope of the pump casing 1. At the same time, since the angles between the multiple arc plates 208 are easy to adjust, it can be adaptively ground according to the different slopes inside the pump casing 1 of different specifications after adjustment, which effectively solves the problem that the existing device cannot grind the slope inside the pump casing 1. Through the setting of the supply pipe 213, when the arc plate 208 is grinding the slope inside the pump casing 1, the contact surface between the arc plate 208 and the pump casing 1 can be continuously supplied with coolant. On the one hand, the heat generated in the grinding area can be cooled to avoid deformation of the casting. On the other hand, the grinding dust can be washed away, the service life of the arc plate 208 is extended, and it can also play a lubricating role.

[0030] A threaded rod 205 is rotatably installed on the middle part of the center plate 204 through an electric slider, and a circular ring is rotatably installed on the front end of the threaded rod 205. A movable plate 206 is hinged in an annular direction on the outer edge of the center plate 204, and a push-pull rod 207 is hinged between the movable plate 206 and the circular ring. An arc plate 208 is fixedly installed on the side of the movable plate 206 away from the push-pull rod 207, and a plurality of water outlet holes are provided on the arc plate 208. An annular box 21 fixed to the turntable 202 is commonly provided on the outside of the plurality of telescopic plates 203, and a supply pipe 213 is fixedly installed on the inner side of the annular box 21, and the ends of the supply pipe 213 away from the annular box 21 are respectively connected to the corresponding arc plates 208.

[0031] When the electric slider is activated to drive the threaded rod 205 to move away from one side of the turntable 202, the sides of the multiple arc plates 208 away from the central plate 204 all move away from each other along the axis of the threaded rod 205. Conversely, when the electric slider is activated to drive the threaded rod 205 to move closer to one side of the turntable 202, the sides of the multiple arc plates 208 away from the central plate 204 all move closer to each other along the axis of the threaded rod 205. By rotating and adjusting the multiple arc plates 208 on the central plate 204, the multiple arc plates 208 can perform circumferential grinding on different slopes at different positions inside the pump casing 1 of different specifications. At the same time, under the action of the supply pipe 213, coolant overflows when the arc plates 208 are grinding, further promoting the grinding effect.

[0032] Two symmetrical fixing members 22 are fixedly installed at the lower part of the U-shaped frame 2. The two fixing members 22 are located between the two moving plates 20. A bidirectional push rod 221 is rotatably installed between the two fixing members 22 through an electric slider. The telescopic ends on both sides of the bidirectional push rod 221 are respectively rotatably connected to the two moving plates 20 through bearings. Active wheels 222 are fixedly installed on both sides of the bidirectional push rod 221.

[0033] When the bidirectional push rod 221 expands and contracts, it can adjust the distance between the two moving plates 20. When the two moving plates 20 approach or move away from each other, the arc plates 208 arranged on the two moving plates 20 can move inside the pump casing 1 to achieve grinding of different positions inside the pump casing 1. By activating the electric slider, the bidirectional push rod 221 can rotate inside the fixing member 22, and when rotating, it synchronously drives the active wheel 222 to rotate. The active wheel 222 drives the driven wheel 231 to rotate through meshing, and when the bidirectional push rod 221 rotates, it drives the rotating column 201 to rotate in the same direction through the action of a belt pulley and a belt. Therefore, the pump casing 1 fixed between the two driven wheels 231 rotates in the opposite direction to the two arc plates 208. While the two arc plates 208 grind the slopes inside the pump casing 1, the pump casing 1 also rotates in the opposite direction to the arc plates 208, further increasing the friction intensity inside the pump casing 1 and effectively improving the grinding efficiency. Compared with the existing grinding device, the present invention can not only grind the inside of the pump casing 1 while rotating, but also rotate the pump casing 1 in the opposite direction along the grinding mechanism, strengthening the grinding efficiency inside the pump casing 1.

[0034] Belt pulleys are fixedly installed on both the bidirectional push rod 221 and the rotating column 201, and a belt is installed between the two belt pulleys. A support frame 23 slidably connected to the U-shaped frame 2 is sleeved outside the bidirectional push rod 221. A driven wheel 231 is rotatably installed in the middle of the support frame 23. The driven wheel 231 meshes with the active wheel 222 behind it. A circumferentially arranged rectangular plate 232 is fixedly installed on the inner wall of the driven wheel 231. A positioning rod 233 for clamping and fixing the side of the pump casing 1 is slidably installed in the middle of the rectangular plate 232.

[0035] The movement of the positioning rod 233 can fix the aperture diameters of the outer edges on both sides of the pump housing 1, so that when the driven wheels 231 on both sides rotate, the pump housing 1 is synchronously driven to rotate in the same direction.

[0036] Cylinders 31 are symmetrically installed on the upper part of the U-shaped frame 2. Support plates 32 are fixedly installed on the lower end faces of the cylinders 31. Middle rods 321 corresponding to the front and back are commonly installed between the two support plates 32. A middle frame 33 is slidably installed between the two middle rods 321. A liquid storage tank 34 is fixedly installed in the middle of the middle frame 33. A spring is arranged on one side of the middle frame 33 and sleeved outside the two middle rods 321. An extrusion plate 323 is arranged on the side of the spring away from the middle frame 33 and sleeved outside the two middle rods 321. An electric push rod 322 is commonly installed between the side of the extrusion plate 323 away from the spring and one of the support plates 32.

[0037] When polishing the outside of the pump housing 1, the cylinders 31 are opened and pushed forward. When the cylinders 31 are pushed forward, the support plates 32 are driven to move downward. When the support plates 32 move downward, the polishing plate 35 is driven to closely adhere to the outer wall of the pump housing 1. As the pump housing 1 rotates, it continuously rubs against the polishing plate 35, so that the polishing plate 35 polishes the pump housing 1 by friction. And the motor is turned on to drive the cam 325 to rotate. The cam 325 intermittently squeezes the semi-circular plate 331 during rotation. After being squeezed, the semi-circular plate 331 slides on the middle rod 321 through the middle frame 33, synchronously driving the polishing plate 35 to slide left and right along the outer edge of the pump housing 1. Furthermore, while the pump housing 1 is rotating and being polished, the left and right sliding of the polishing plate 35 can also polish the outer wall of the pump housing 1 in the left and right directions. The electric push rod 322 drives the extrusion plate 323 to move left and right on the middle rod 321 by telescoping. When the extrusion plate 323 moves, it squeezes the spring, so as to adjust the polishing range of the polishing plate 35 during left and right polishing.

[0038] A moving frame 324 is arranged on the side of the middle frame 33 away from the spring and outside the two middle rods 321. The moving frame 324 is slidably connected to the middle rod 321 through an electric slider. A cam 325 is rotatably installed below the moving frame 324 through a motor. A semi-circular plate 331 fixedly connected to the middle frame 33 is arranged on one side of the cam 325.

[0039] A polishing plate 35 arranged in a convex shape is fixedly installed at the lower end of the middle frame 33. A convex groove is formed in the middle of the polishing plate 35. Inner plates 352 are installed in the convex groove through springs on both sides of the convex groove and slide in the convex groove. A vertical pipe 351 is fixedly installed in the middle of the upper end face of the polishing plate 35. The two ends of the vertical pipe 351 are communicated with the liquid storage tank 34 and the convex groove respectively. An inner rod 353 is fixedly installed on the upper end face of the inner plate 352. A sealed plug in a conical shape is arranged at the top of the inner rod 353. A conical groove adapted to the sealed plug is formed at the lower end of the liquid storage tank 34.

[0040] When the grinding plate 35 moves downward and contacts the outer wall of the pump housing 1, the built-in plate 352 moves upward in the convex groove under the reaction force of the pump housing 1. When the built-in plate 352 moves upward, it synchronously drives the built-in rod 353 to move upward. When the built-in rod 353 moves upward, the sealing plug at its end cancels the blockage of the conical groove. At this time, the coolant in the liquid storage tank 34 flows along the conical groove and the vertical pipe 351 to the built-in plate 352, and finally flows through the convex groove to the grinding surface between the grinding plate 35 and the pump housing 1, cooling the high temperature generated during the grinding of the pump housing 1 and realizing the lubrication of the grinding plate 35.

[0041] On one side of the vertical pipe 351, a side pipe 355 communicating with its inner cavity is fixedly installed. At the end of the side pipe 355 away from the vertical pipe 351, a side box 354 fixedly connected to the side of the middle frame 33 is fixedly installed. Transmission pipes 212 are respectively installed on both sides of the side box 354. At the end of the transmission pipe 212 away from the side box 354, a rotating member 211 is fixedly installed. The rotating member 211 is slidably connected to the outer edge of the annular box 21. Through the setting of the side pipe 355, the coolant can flow into the side box 354 when passing through the vertical pipe 351, and the annular box 21 is supplied with coolant through the transmission pipe 212.

[0042] On one side of the grinding plate 35, a plurality of top boxes 36 are fixedly installed. On one side of the plurality of top boxes 36, a collecting box 361 is fixedly installed together. On the side of the collecting box 361 away from the top box 36, an air suction pipe 363 communicating with its inner cavity is fixedly installed. A fan is arranged inside the air suction pipe 363. On the side of the air suction pipe 363 away from the collecting box 361, a driving box 364 is fixedly installed. A moving rod 365 is slidably installed in the middle of the driving box 364. At the bottom end of the moving rod 365, a driven wedge block 366 is fixedly installed.

[0043] A spring is sleeved outside the moving rod 365 between the driven wedge block 366 and the driving box 364. At the top end of the moving rod 365, a first control valve 367 is fixedly installed. At one end of the driving box 364 close to the air suction pipe 363, a second solenoid valve 368 electrically connected to the fan is fixedly installed. A sliding rod 37 is slidably installed on the front side of the U-shaped frame 2 from left to right. At the top of the sliding rod 37, a telescopic member 371 arranged in an L shape is fixedly installed. The end of the telescopic member 371 away from the sliding rod 37 is connected to the liquid storage tank 34. At the end of the sliding rod 37 away from the U-shaped frame 2, a driving wedge block 372 is fixedly installed.

[0044] When the grinding plate 35 moves downward, it synchronously drives the driven wedge block 366 to move downward. When the driven wedge block 366 moves downward, it contacts the driving wedge block 372. The driving wedge block 372 generates a reverse acting force on the driven wedge block 366. At this time, the driven wedge block 366 moves upward. When the driven wedge block 366 moves upward, the first control valve 367 and the second solenoid valve 368 are in contact and the fan in the air suction pipe 363 is turned on to suck air. At this time, the top box 36 adsorbs the dust generated during grinding into the collecting box 361 and then discharges it.

[0045] When the first control valve 367 moves up and contacts the second solenoid valve 368, the fan starts to operate. After the first control valve 367 cancels the contact with the second solenoid valve 368, the fan stops operating.

[0046] When the present invention is in use, the electric slider is opened to allow the two movable plates 20 to slide towards each other or away from each other, so that the pump casing 1 of flood control pumps of different specifications can be polished, and the center plate 204 is driven to move inside the pump casing 1 by the extension and retraction of the telescopic plate 203, so that the inside of the pump casing 1 can be evenly polished, and the threaded rod 205 is driven to move left and right in the middle of the center plate 204 by the electric slider. When the threaded rod 205 moves, the angles between the multiple movable plates 206 can be adjusted through the ring and the push-pull rod 207. When the movable plate 206 rotates along the axis of the center plate 204, the angles between the multiple arc plates 208 can be adjusted, so that the multiple arc plates 208 are matched with the inclined surface inside the pump casing 1, so that when the turntable 202 rotates, multiple arcs The plates 208 rotate synchronously to realize the circular rotation grinding of the slope inside the pump casing 1. Compared with the existing device, the present invention can grind the internal inclined surface of the pump casing 1. At the same time, because the angles between the multiple arc plates 208 are easy to adjust, it can be adaptively ground according to the different slopes inside the pump casing 1 of different specifications after adjustment, which effectively solves the problem that the existing device cannot grind the inclined surface inside the pump casing 1. Through the setting of the supply pipe 213, when the arc plate 208 grinds the inclined surface inside the pump casing 1, the contact surface between the arc plate 208 and the pump casing 1 can be continuously supplied with coolant. On the one hand, the heat generated in the grinding area can be cooled to avoid deformation of the casting. On the other hand, the grinding dust can be washed away, the service life of the arc plate 208 is extended, and it can also play a lubricating role. The bidirectional push rod 221 can adjust the distance between the two movable plates 20 when it is extended and retracted. When the two movable plates 20 are moved closer to or farther away from each other, the arc plates 208 arranged on the two movable plates 20 can be moved inside the pump housing 1 to achieve grinding of different positions in the pump housing 1. The bidirectional push rod 221 can be rotated in the fixing member 22 by opening the electric slider, and the driving wheel 222 is driven to rotate synchronously during the rotation. The driving wheel 222 drives the driven wheel 231 to rotate through meshing, and the bidirectional push rod 221 is driven by the pulley and the belt during the rotation. The action drives the rotating column 201 to rotate in the same direction as the driven wheel 231, so the pump housing 1 fixed between the two driven wheels 231 rotates in the opposite direction to the circular arc plates 208 on both sides. While the circular arc plates 208 on both sides are grinding the slope surface inside the pump housing 1, the pump housing 1 also rotates in the opposite direction to the circular arc plates 208, further increasing the friction strength inside the pump housing 1 and effectively improving the grinding efficiency. Compared with the existing grinding device, the present invention can grind the inside of the pump housing 1 while rotating, and can also rotate the pump housing 1 in the opposite direction of the grinding mechanism, thereby enhancing the grinding efficiency inside the pump housing 1; The apertures on the outer edges of the two sides of the pump housing 1 can be fixed by moving the positioning rods 233, so that when the driven wheels 231 on both sides rotate, the pump housing 1 is synchronously driven to rotate in the same direction, the cylinder 31 is turned on to push forward, and the support plate 32 is driven to move downward when the cylinder 31 is pushed forward, and the support plate 32 is driven to move downward when the support plate 32 is moved to be close to the outer wall of the pump housing 1, and the pump housing 1 is continuously rubbed against the grinding plate 35 as the pump housing 1 rotates, so that the grinding plate 35 rubs and grinds the pump housing 1, and the motor is turned on to drive the cam 325 to rotate, and the cam 325 intermittently squeezes the semicircular plate 3 when it rotates. 31. After being squeezed, the semicircular plate 331 slides on the middle rod 321 through the middle frame 33, and synchronously drives the grinding plate 35 to slide left and right on the outer edge of the pump housing 1, thereby realizing that while the pump housing 1 is rotatingly polished, the grinding plate 35 slides left and right and can also polish the outer wall of the pump housing 1 in the left and right directions. The extrusion plate 323 is driven to move left and right on the middle rod 321 through the extension and contraction of the electric push rod 322. The extrusion plate 323 squeezes the spring when moving, so that the grinding range of the grinding plate 35 when grinding left and right can be adjusted; When the grinding plate 35 moves downward and contacts the outer wall of the pump casing 1, the built-in plate 352 is subjected to the reaction force of the pump casing 1 and moves upward in the convex groove. When the built-in plate 352 moves upward, the built-in rod 353 is simultaneously driven to move upward. When the built-in rod 353 moves upward, the sealing plug at the end of the built-in rod cancels the blockage of the conical groove. At this time, the coolant in the liquid storage tank 34 flows along the conical groove and the vertical pipe 351 to the built-in plate 352, and finally flows through the convex groove to the grinding surface between the grinding plate 35 and the pump casing 1, so as to cool down the high temperature generated when the pump casing 1 is ground and realize the lubrication of the grinding plate 35. By setting the side pipe 355, the coolant can flow through the vertical pipe 351 to the grinding surface between the grinding plate 35 and the pump casing 1. 51 is retained in the side box 354, and the cooling liquid is supplied to the annular box 21 through the transmission pipe 212. When the grinding plate 35 moves downward, the driven wedge block 366 is simultaneously driven to move downward. When the driven wedge block 366 moves downward, it contacts with the active wedge block 372. The active wedge block 372 generates a reverse force on the driven wedge block 366. At this time, the driven wedge block 366 moves upward. When the driven wedge block 366 moves upward, the first control valve 367 and the second solenoid valve 368 contact each other, and then the suction effect is turned on the fan in the suction pipe 363. At this time, the top box 36 absorbs the dust generated during grinding into the collection box 361 and then discharges it.
