When the cooling water slides down along the cavity wall of the water inlet cavity, it will take away part of the heat on the surface of the pump body, thereby cooling the surface of the pump body and enhancing the heat dissipation effect. When the piston rod moves up in the hollow rod, the space between the bottom end of the piston rod and the upper surface of the base in the hollow rod will become larger, and the cooling water in the water storage box will enter the hollow rod from the water inlet hose. No additional electric drive device is required, and no additional electricity cost will be incurred. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Reference Figure 1-Figure 10 , an ultra-high pressure water pump, comprising a base 1, a pump body 2 is fixedly mounted on the upper surface of the base 1 through multiple pairs of telescopic components, a pump head 3 is arranged at one end of the pump body 2, a plurality of mounting holes 26 are opened in a circumferential shape on the surface of the pump head 3, a plurality of mounting holes 26 are rotatably arranged in each of the plurality of mounting holes 26, a plurality of threaded holes 5 are opened in a circumferential shape on the end surface of one end of the pump body 2 for threaded mounting of the plurality of fixing bolts 4, a water inlet pipe 22 is fixedly mounted on the upper surface of the pump body 2, a filter screen 24 is arranged in the water inlet pipe 22, and the filter screen 24 is used to filter impurities in the water;

[0033] The surface of the pump head 3 is rotatably mounted with a plurality of rotating shafts 6, a gear 7 is fixedly sleeved on the rotating shaft 6, a limiting block 9 is fixedly mounted on the surface of the gear 7 through a U-shaped connecting rod 8, the surfaces of the plurality of limiting blocks 9 are respectively in sliding contact with the end faces of the plurality of fixing bolts 4, an annular groove 10 is provided on the surface of the pump head 3, the annular groove 10 is slidably configured with a gear ring 11 meshingly connected with the plurality of gears 7 through a sliding component, the sliding component comprises a plurality of sliding rods 12 fixedly mounted on the surface of the gear ring 11 in a circumferential shape, the ends of the plurality of sliding rods 12 away from the gear ring 11 are all slidably configured in the annular groove 10, the gear 7 is connected to the pump head 3 through an elastic component, the elastic component comprises a torsion spring 13 sleeved on the rotating shaft 6, the two ends of the torsion spring 13 are respectively fixedly connected with the surface of the gear 7 and the surface of the pump head 3;

[0034] When the pump head 3 needs to be installed, firstly, the surface of the pump head 3 is abutted against the end surface of the pump body 2, and the pump head 3 is rotated so that the multiple mounting holes 26 correspond to the positions of the multiple threaded holes 5 respectively, and then by rotating the gear ring 11, the multiple gears 7 meshing with the gear ring 11 will rotate, and respectively drive the multiple rotating shafts 6 to rotate, so that the multiple limiting blocks 9 no longer correspond to the positions of the multiple mounting holes 26 respectively, and then the multiple fixing bolts 4 are respectively passed through the multiple mounting holes 26, and are respectively threadedly installed in the multiple threaded holes 5, and then the gear ring 11 is loosened again, and the multiple gears 7 will respectively rotate and reset rapidly under the elastic potential energy of the multiple torsion springs 13, the gear ring 11 will also rotate and reset, and the multiple limiting blocks 9 will rapidly rotate and reset, and the surfaces of the multiple limiting blocks 9 will respectively abut against the surfaces of the multiple fixing bolts 4, thereby limiting the movement of the multiple fixing bolts 4, and preventing the fixing bolts 4 from rotating and moving due to the vibration force generated during the operation of the pump body 2, thereby causing the connection between the pump head 3 and the pump body 2 to become loose, thereby improving the stability of the fixed pump head 3;

[0035] When the pump head 3 needs to be disassembled, it is only necessary to rotate the gear ring 11 to control the rotation of the multiple gears 7 so that the multiple limit blocks 9 no longer respectively abut against the multiple fixing bolts 4. At this time, the fixing bolts 4 can be tightened to remove them from the threaded holes 5 and the mounting holes 26.

[0036] The telescopic assembly includes a hollow rod 14, a piston rod 15 slidably inserted in the hollow rod 14, and a telescopic spring 16 located in the hollow rod 14. The bottom end of the hollow rod 14 is fixedly connected to the upper surface of the base 1, and the two ends of the telescopic spring 16 are respectively fixedly connected to the bottom end of the piston rod 15 and the upper surface of the base 1, and the top end of the piston rod 15 is fixedly connected to the surface of the pump body 2.

[0037] When the pump body 2 is working, it will vibrate. When the pump body 2 vibrates, the multiple telescopic springs 16 will expand and contract, and the multiple piston rods 15 will also move vertically back and forth in the multiple hollow rods 14, which can effectively reduce and alleviate the impact force, thereby achieving shock absorption.

[0038] A water storage box 17 is fixedly installed on the upper surface of the base 1, and the water storage box 17 is filled with cooling water. A plurality of water cooling components are arranged on the surface of the pump body 2, and the water cooling components are used to dissipate heat from the surface of the pump body 2. The piston rod 15 is inserted in the hollow rod 14 in a sliding seal. The water cooling component includes two arc rods 18 symmetrically fixedly installed on the surface of the pump body 2, and a water inlet cavity 25 is opened in the arc rod 18. A water inlet hose 19 and a water outlet hose 20 are fixedly installed on the surface of the hollow rod 14, and one end of each of the plurality of water inlet hoses 19 is connected to the hollow rod 14. The water storage box 17 is connected, one end of the plurality of water outlet hoses 20 is respectively connected to the top of the plurality of arc-shaped rods 18, and a one-way valve is provided in the water inlet hose 19 and the water outlet hose 20. The conducting direction of the one-way valve in the water inlet hose 19 is from the water storage box 17 to the hollow rod 14, and the conducting direction of the one-way valve in the water outlet hose 20 is from the hollow rod 14 to the water inlet cavity 25. A return hose 21 is fixedly installed at the bottom end of the arc-shaped rod 18, and the bottom ends of the plurality of return hoses 21 are all connected to the water storage box 17;

[0039] When the pump body 2 is working and vibrating, the multiple piston rods 15 will respectively move vertically back and forth in the multiple hollow rods 14. When the piston rod 15 moves down in the hollow rod 14, the space between the bottom end of the piston rod 15 and the upper surface of the base 1 in the hollow rod 14 will become smaller, and the cooling water in the hollow rod 14 will enter the water inlet cavity 25 from the water outlet hose 20, and slide down along the arc-shaped cavity wall of the water inlet cavity 25 under the action of its own gravity, and then enter the water storage box 17 from the water return hose 21. When the cooling water slides down along the cavity wall of the water inlet cavity 25, it will take away part of the heat on the surface of the pump body 2, thereby cooling the surface of the pump body 2 and enhancing the heat dissipation effect. When the hollow rod 14 moves upward, the space between the bottom end of the piston rod 15 and the upper surface of the base 1 in the hollow rod 14 will become larger, and the cooling water in the water storage box 17 will enter the hollow rod 14 from the water inlet hose 19. When the piston rod 15 moves downward next time, the cooling water in the hollow rod 14 will enter the water inlet chamber 25 from the water outlet hose 20 again. This reciprocating process can achieve the effect of dissipating heat on the surface of the pump body 2, avoiding the pump body 2 from working for a long time, generating more heat and accumulating on the surface of the pump body 2, thereby causing the surface temperature of the pump body 2 to be higher, affecting the normal operation of the pump body 2, and the supply of cooling water does not require an additional electric drive device, so that no additional electricity cost will be generated.

[0040] A spherical groove is formed at one end of the slide rod 12 away from the gear ring 11, and a ball 23 is rolled and embedded in the spherical groove. Multiple balls 23 are in rolling contact with the annular groove 10. The balls 23 can reduce the friction between the end of the slide rod 12 and the contact surface of the annular groove 10, thereby avoiding jamming when the gear ring 11 rotates.

[0041] In the present invention, when the pump head 3 needs to be installed, the surface of the pump head 3 is firstly abutted against the end surface of the pump body 2, and the pump head 3 is rotated so that the plurality of mounting holes 26 correspond to the positions of the plurality of threaded holes 5 respectively. Then, by rotating the gear ring 11, the plurality of gears 7 meshingly connected with the gear ring 11 will rotate, and respectively drive the plurality of rotating shafts 6 to rotate, so that the plurality of limiting blocks 9 no longer correspond to the positions of the plurality of mounting holes 26 respectively. At this time, the plurality of fixing bolts 4 are respectively passed through the plurality of mounting holes 26, and are respectively threadedly installed in the plurality of threaded holes 5. At this time, if the gear ring 11 is loosened, the multiple gears 7 will quickly rotate and reset under the elastic potential energy of the multiple groups of elastic components, the gear ring 11 will also rotate and reset, and the multiple limiting blocks 9 will quickly rotate and reset. The surfaces of the multiple limiting blocks 9 will respectively abut against the surfaces of the multiple fixing bolts 4, thereby limiting the movement of the multiple fixing bolts 4 and preventing the fixing bolts 4 from rotating and moving due to the vibration force generated during the operation of the pump body 2, thereby causing the connection between the pump head 3 and the pump body 2 to loosen, thereby improving the stability of the fixed pump head 3.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
