[0003] When using an automatic self-priming pump, most of them are placed in the desired position. In order to ensure that the automatic self-priming pump can work normally, the automatic self-priming pump needs to be adjusted to a horizontal state before use to avoid problems such as penetration and inability to fully exert its performance. When adjusting it to a horizontal state, most of them rely on manual pushing to tilt the automatic self-priming pump and fill pads at the bottom to make it in a horizontal state. This adjustment method not only requires multiple people to cooperate in adjusting the position of the automatic self-priming pump, but also requires multiple debugging to adjust it to a horizontal state, which is inconvenient and needs to be improved.

DETAILED DESCRIPTION

[0029] 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.

[0030] See also Figures 1 to 10The present invention provides a technical solution: a self-controlled self-priming pump with a changeable position, which is used to change the position of the self-controlled self-priming pump so that it can be adjusted to a horizontal state before use, including a base 1, a battery is arranged on the base 1, and the battery is connected to the hydraulic push rod on the base 1 through a line. A plurality of universal wheels with self-locking function in the prior art are installed at the bottom end of the base 1, and the universal wheels can be used to facilitate the base 1 to be moved to a desired position for use. A support assembly 2 is arranged at the top center position of the base 1, and the support assembly 2 includes a support seat 30, and a groove is arranged at the top center position of the support seat 30, and a plurality of buffer elements 3 are fixedly installed in the groove, and the buffer elements 3 are all made of the prior art. The hydraulic push rod in the operation is made, and a mounting plate is installed on the top of the hydraulic push rod, a rubber pad is fixedly installed on the top of the mounting plate, a supporting slide groove 31 is arranged on the top of the support seat 30, and the supporting slide groove 31 is a circular slide groove. The supporting slide groove 31 is located on the periphery of the three buffer elements 3 to avoid directly controlling the pump body 6 to fall onto the circular ring 12 after the circular ring 12 is adjusted to a horizontal state, causing damage to the circular ring 12. A tray 32 is fixedly installed on the outer wall of the support seat 30, and a fixing ring 33 is arranged below the tray 32. The fixing ring 33 is fixedly installed on the top of the base 1, and a guide groove 34 is arranged on the fixing ring 33. The guide groove 34 is a circular groove, which is pushed and installed by the hydraulic push rod The plate moves upward, which can facilitate the control of the lifting movement of the pump body 6 during use. After the ring 12 and the supporting surface 13 are adjusted to a horizontal state, the pump body 6 is pushed upward by the buffer element 3 to make the pump body 6 break away from the contact between the bottom plate 8, and then the buffer element 3 is contracted to make the pump body 6 move downward to fit on the supporting surface 13 of the ring 12. A temporary supporting component 4 is arranged on the top of the tray 32, and a horizontal adjustment component 5 is arranged on the support seat 30. The top of the temporary supporting component 4 is provided with a pump body 6. The pump body 6 is an automatic self-priming pump in the prior art. The bottom end of the pump body 6 is provided with three openings that match the diameter size of the mounting plate of one of the structures composed of the buffer element 3. The mounting plate is made of a rubber plate to prevent the mounting plate from being unable to be placed in the opening at the bottom of the pump body 6 after the pump body 6 is adjusted to a horizontal state. After the mounting plate is placed in the opening at the bottom of the pump body 6, the pump body 6 can be prevented from rotating during use. The rubber pad on the mounting plate, which is one of the components of the buffer element 3, is placed inside the pump body 6 to prevent the vibration generated by the pump body 6 during use from excessively affecting the normal operation of the buffer element 3. The supporting surface 13 on the ring 12 provides support for the pump body 6 during its later use, to avoid relying solely on the buffer element 3 to provide support for the pump body 6, which results in a reduction in the service life of the hydraulic push rod, which is one of the components of the buffer element 3.

[0031] The horizontal adjustment component 5 includes a support frame 29, a ring 12, and a plurality of sliding mounting plates 16. A plurality of support columns 35 are arranged at the bottom end of the support frame 29. The diameter of the support column 35 matches the support slide groove 31.

A plurality of mounting frames 21 are arranged at the top of the support frame 29. The top of the mounting frame 21 is provided with a groove, and a rotating shaft 22 is rotatably installed in the groove. The outer wall of the rotating shaft 22 is fixedly installed with an assembling plate 23 and a linkage plate 25. The top of the linkage plate 25 is provided with a A fixing block 26 is provided with a groove at the top of the fixing block 26, and a rotating rod 27 is rotatably installed in the groove on the fixing block 26, a connecting block 28 is provided at the top of the rotating rod 27, and the top of the connecting block 28 is connected to the ring 12 through a hinge, a fitting groove is provided on the assembling plate 23, and an L-shaped fitting plate 24 is movably installed in the fitting groove, the rotating shaft 22 is driven to rotate by the L-shaped fitting plate 24 and the assembling plate 23, so that the linkage plate 25 will rotate synchronously, and at this time, the connecting block 28 located on the linkage plate 25 will fine-tune the position of the ring 12 during the jacking process, so that the ring 12 can be adjusted to a horizontal state.

[0032] A protrusion is fixedly installed on the outer wall of the ring 12, and a spirit level 15 is arranged on the protrusion. The spirit level 15 can adopt the tubular spirit level in the prior art. A concave supporting surface 13 is arranged on the inner ring side wall of the ring 12, and the inner ring diameter of the ring 12 is the same as the bottom end diameter of the pump body 6, so that the pump body 6 can be stably installed in the ring 12 and located at the top of the supporting surface 13. A plurality of anti-roll plates 14 are arranged on the top of the ring 12. The vertically installed anti-roll plates 14 can facilitate the anti-roll plates 14 to partially fit the outer wall of the pump body 6 during use, so that the pump body 6 moves downward when being manipulated by the buffer element 3, guiding the pump body 6 to fall onto the supporting surface 13 on the ring 12, and avoiding the pump body 6 from shaking excessively and tipping over during the process of lifting and lowering the position.

[0033] The sliding mounting plate 16 is composed of two L-shaped fixing frames and an arc-shaped plate. The two L-shaped fixing plates are connected into a whole by the arc-shaped plate. The width of the short head of the L-shaped fixing frame is the same as the width of the guide groove 34. By placing the short head of the two L-shaped fixing frames into the guide groove 34, and the curvature of the short head of the L-shaped fixing plate is the same as the curvature of the inner wall of the guide groove 34, the L-shaped fixing plate can slide in the guide groove 34. The tops of the two L-shaped fixing plates that form the structure of the sliding mounting plate 16 are both provided with sliding grooves, and the two sliding grooves are both sliding. The two adjusting plates 17 are movably mounted with an adjusting plate 17, a connecting plate 19 is commonly connected to the two adjusting plates 17, and a threaded through hole is provided on the connecting plate 19, and a supporting screw 20 is provided in the threaded through hole, and the supporting screw 20 can be movably fitted on the outer wall of the L-shaped fitting plate 24, and a plurality of nuts are movably sleeved on the outer wall of the supporting screw 20, and the nuts can be used to prevent the waist of the supporting screw 20 from bending due to excessive force when the L-shaped fitting plate 24 is supported by the supporting screw 20, and the tops of the two adjusting plates 17 are movably mounted. The plug-in assembly 18 is dynamically attached, and the plug-in assembly 18 is composed of a fixed plate and a plug-in rod. The plug-in rod penetrates the fixed plate and extends to the bottom of the fixed plate, and the top of the adjustment plate 17 is provided with a plurality of plug-in holes for fixing the plug-in rod, and the sliding mounting plate 16 is located directly below the plug-in rod and is also provided with a through hole matching the diameter of the plug-in rod. The plug-in rod is made of a screw. According to the inclination of the base 1 in the actual use environment of the pump body 6, the adjustment plate 17 can be controlled to slide and adjust the distance between it and the pump body 6 to avoid the support screw. The distance between the rod 20 and the L-shaped fitting plate 24 and the connecting plate 19 is too large, resulting in excessive force length of the support screw 20, thereby providing protection for the support screw 20, and fixing the position of the adjustment plate 17 by passing the insertion rod on the insertion assembly 18 through the fixed plate and inserting it into the insertion hole on the adjustment plate 17, and rotating the insertion rod to pass through the sliding mounting plate 16, the adjustment plate 17 and fit the top of the base 1, and the friction between the bottom end of the insertion rod and the base 1 prevents the sliding mounting plate 16 from easily shifting in the guide groove 34.

[0034] By controlling the adjustment plate 17 to slide and adjust its position on the sliding mounting plate 16 according to the inclination of the base 1 during installation, and fixing the position of the adjustment plate 17 by the plug-in assembly 18, at this time, by controlling the support screw 20 to rotate, the support screw 20 is made to contact the L-shaped bonding plate 24, so that the L-shaped bonding plate 24 drives the assembly plate 23 to rotate through the rotating shaft 22, and the linkage plate 25 on the rotating shaft 22 is rotated synchronously, at this time, the connecting block 28 located on the linkage plate 25 cooperates with the rotating rod 27 and the hinge to fine-tune the ring 12 and adjust the ring 12 to a horizontal state.

[0035] The temporary supporting assembly 4 includes a rotating frame 10 and several fixed frames 7. The fixed frames 7 are fixedly installed on the top of the tray 32 and close to the outer wall of the support seat 30. The top of the fixed frame 7 is provided with a groove, and a bottom support plate 8 is rotatably installed in the groove. The bottom end of the bottom support plate 8 is movably fitted with a support block 9. By placing the support block 9 in the groove on the fixed frame 7 and fitting the inner wall of the bottom end of the groove and the bottom support plate 8, the downward movement of the bottom support plate 8 can be limited. At this time, a temporary support effect can be provided to the pump body 6 by several bottom support plates 8, and the pump body 6 can be prevented from tipping over by the anti-tilt plate 14. The rotating frame 10 is composed of a rotating ring, a connecting ring, and several supporting rods. The diameter size of the rotating ring and the connecting ring is the same as the diameter size of the tray 32, so that the tray 32 can support the rotating ring and the connecting ring The upper and lower ends of the support rod are respectively fixedly connected to the rotating ring and the connecting ring, and a plurality of strips 11 are fixedly installed on the outer wall of the connecting ring. The support block 9 is composed of a square and a U-shaped tube. The U-shaped tube is fixedly installed on the square, and the connecting ring passes through the U-shaped groove on the U-shaped tube, so that during the rotation of the connecting ring, the support block 9 is pried by the strip 11 to disengage the support block 9 from between the grooves on the bottom plate 8 and the fixing frame 7, and push the bottom plate 8 to rotate upward to disengage from the lifting space of the pump body 6, so that the pump body 6 can fit the supporting surface 13 on the circular ring 12 under the guidance of the buffer element 3. The connecting ring and the rotating ring are both movably mounted on the outer wall of the fixing frame 7, and the outer wall of the fixing frame 7 is an arc that matches the connecting ring and the rotating ring, ensuring that the connecting ring and the rotating ring can both perform circular motion.

[0036] When the present invention is in use, the base 1 is pushed to move to a desired position, and the adjustment plate 17 is controlled to slide and adjust the position on the sliding mounting plate 16 according to the horizontal data provided by the level meter 15, and the position of the adjustment plate 17 is fixed by the plug-in assembly 18, and the support screw 20 is rotated to make the support screw 20 contact the L-shaped bonding plate 24, so that the L-shaped bonding plate 24 drives the assembly plate 23 to rotate through the rotating shaft 22, and the linkage plate 25 on the rotating shaft 22 is synchronously rotated. At this time, the connection plate 25 located on the linkage plate 25 The block 28 cooperates with the rotating rod 27 and the hinge to fine-tune the ring 12 and adjust the ring 12 to a horizontal state. At this time, the pump body 6 is located at the top of the three supporting plates 8. The buffer element 3 pushes the pump body 6 upward to make it break away from the contact with the supporting plates 8, and then controls the rotating frame 10 to rotate, so that the lever 11 on the rotating frame 10 pulls the support block 9 to move out of the groove on the fixed frame 7, and controls the buffer element 3 to move downward so that the pump body 6 is transferred to the supporting surface 13 on the ring 12, and the pump body 6 can be started for use.
