Description

Technical Field

[0001] This invention relates to the field of high-pressure water pump protection technology, specifically a protective device for high-pressure water pumps. Background Technology

[0002] High-pressure water pumps refer to power equipment with a working pressure greater than 1.0 MPa, used for conveying high-pressure liquids, achieving high-pressure cleaning, pressure testing, pressurization, and fluid transportation. These include, but are not limited to, plunger pumps, centrifugal pumps, and multistage booster pumps. They are widely used in industrial cleaning, high-pressure testing, chemical transportation, fire fighting, and water treatment (reverse osmosis), operating under harsh conditions and with concentrated risks. High-pressure water pump protective devices are mechanical structures or electrical control protection components installed in the pump body, pipelines, drive end, or control circuit of the high-pressure water pump to limit working pressure, prevent overload, suppress water hammer impact, avoid idling damage, isolate hazardous conditions, and ensure the safety of equipment and personnel. However, existing high-pressure water pump protective devices have the following defects in actual use: In actual operation, high-pressure water pumps rely on a turbocharged rotary structure to pump water. The high-speed rotation of the internal impeller generates strong centrifugal force, driving the water flow at high speed. During this process, uneven water flow distribution, speed fluctuations, and pressure pulsations can cause significant high-speed vibration and shaking of the pump body. Prolonged exposure to severe vibration can easily lead to fatigue wear, loosening, and even deformation and cracking of core components such as bearings, seals, and drive shafts within the pump body. This not only exacerbates equipment wear but also significantly shortens the overall service life of the high-pressure water pump, increasing usage and maintenance costs. Furthermore, most existing high-pressure water pump-equipped damping structures are of fixed stiffness and damping, unable to adjust the damping effect in real time according to different operating parameters such as pump pressure, flow rate, and speed. Their adaptability and versatility are poor, making it difficult to achieve ideal vibration protection in various working scenarios. In addition, high-pressure water pumps operate in harsh environments with humid, high-pressure, and water-rich media. The connecting bolts at the pump-water pipe connection are subject to long-term water immersion, corrosion, and media erosion, making them highly susceptible to rust and seizure. Corroded bolts make subsequent installation and disassembly extremely difficult, significantly reducing equipment inspection and maintenance efficiency. In severe cases, connection failure and pipe detachment can lead to safety hazards such as leaks and collapses. Furthermore, high-pressure water pumps operate with continuous high-speed vibration, while their external protective casing is typically fixed and stationary, resulting in significant relative movement between the pump body and the casing. Under long-term vibration and relative displacement, the connection point between the pump body and the pipeline is prone to misalignment and displacement. This leads to loose sealing surfaces and uneven stress on the seals, resulting in decreased sealing performance and problems such as leaks and pressure drops. This not only affects pump efficiency but also further exacerbates equipment damage and safety risks.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0009] Preferably, the right end of the guide pin is slidably embedded inside the inclined guide groove, and the drive internal gear ring is meshed with the four first driven gears.

[0010] Preferably, the lower end of the first threaded rod extends into the interior of the movable cylinder, and the first threaded rod and the first threaded cylinder are connected by a thread, and the bottom of the first threaded cylinder and the top of the adjusting block are fixedly connected by bolts.

[0011] Preferably, the vibration-adaptive sealing adjustment assembly includes a slider, which is slidably connected to a groove on the left side of the upper surface of the base. A wedge is fixedly connected to the right side of the slider, and a return spring is installed between the lower right side of the slider and the inner wall of the groove. A lifting plate is bolted to the left side of the lower surface of the mounting plate, and a fitting block is rotatably connected to the bottom of the lifting plate via a shaft.

[0012] Preferably, the left side of the slider is fixedly connected to the right side of the sealing protective shell by bolts, the wedge block is positioned corresponding to the lifting plate, and the wedge block is in contact with the inclined surface of the linkage block.

[0013] Preferably, the upper end of the second threaded rod extends into the interior of the mounting plate, and the second threaded rod is connected to the mounting plate and the lifting plate by a bearing, and the second driven gear is meshed with the drive internal gear ring.

[0014] Preferably, the second threaded cylinder and the second threaded rod are connected by a thread, and the bottom of the second threaded cylinder and the top of the linkage block are connected by a hinge.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs a composite shock-absorbing structure combining shock-absorbing springs and airbags. When the water pump vibrates during operation, the movable cylinder reciprocates relative to the fixed cylinder, compressing the shock-absorbing springs. This initially absorbs and buffers vibration energy, reducing the impact of vibration on the main body of the equipment. Simultaneously, the compression and expansion of the gas inside the airbag further dissipates vibration energy, forming a composite shock-absorbing system of springs and airbags. This significantly improves the shock absorption effect, reducing the vibration amplitude and operating noise of the equipment. The gas discharged under pressure from the shock-absorbing airbags can enter the circumferentially distributed annular sealing airbags, causing them to expand adaptively and tightly adhere to the outer wall of the water pipe and the inner wall of the sealing protective shell. As vibration intensifies, the sealing pressure and sealing area automatically increase, forming an adaptive sealing structure. This effectively prevents the sealing gap from widening and media leakage caused by vibration and displacement. The sealing protective shell encloses the connecting bolts, isolating them from external humid and corrosive environments, preventing bolt rust and jamming, facilitating later disassembly and maintenance, and preventing corrosive media from intruding into the connection parts. This eliminates the risk of equipment loosening and falling off due to bolt failure, improving the reliability and service life of the device.

[0016] 2. This invention enables adaptive adjustment of damping resistance based on vibration amplitude. When the internal gear ring moves axially with the movable cylinder, it synchronously rotates circumferentially under the cooperation of the guide pin and the inclined guide groove. The greater the vibration amplitude, the greater the axial stroke and circumferential rotation angle of the internal gear ring, thus achieving adaptive linkage between vibration amplitude and rotation angle. The internal gear ring drives the first driven gear and the first threaded rod to rotate, causing the first threaded cylinder to move axially. By adaptively changing the preload and damping resistance of the damping spring through the adjusting block, excessive amplitude can be effectively suppressed, avoiding severe vibration of the water pump and significantly improving damping stability and equipment operational reliability.

[0017] 3. The sealing structure of this invention can adaptively compensate for displacement in response to vibration. The vibration of the water pump drives the lifting plate and the contact block to reciprocate, continuously squeezing the wedge block and cooperating with the return spring, so that the sealing protective shell moves back and forth at the same frequency as the water pump vibration, always maintaining the appropriate relative position with the water pipe and connecting bolts. With the help of the annular sealing airbag, it further compensates for vibration displacement deviation, significantly improving the sealing reliability. At the same time, the driving internal gear ring can drive the second driven gear and the second threaded cylinder to move, realizing adaptive adjustment of the tilt angle of the contact block, so that the displacement of the sealing protective shell matches the vibration amplitude of the water pump, realizing the synergistic effect of shock absorption and sealing, and further improving the overall operational stability and sealing effect of the device.

[0020] To further illustrate the technical means and effects adopted by the present invention in order to achieve the intended purpose, the following detailed description is provided in conjunction with the accompanying drawings and preferred embodiments, based on the specific implementation methods, structures, features and effects of the present invention.

[0021] Please see Figures 1-8 This invention provides a technical solution: a protective device for a high-pressure water pump, comprising a base 1, an mounting plate 2 disposed on the upper right side of the base 1, and a water pump body 3 mounted on the upper surface of the mounting plate 2. A fixed cylinder 5 and a movable cylinder 6 are respectively connected between the mounting plate 2 and the base 1. A sealing protective shell 4 is fitted onto the outer side of the output end of the water pump body 3, and two sealing protective shells 4 are connected together by a flange. It also includes an adjusting block 8, which is slidably disposed inside the fixed cylinder 5. A shock-absorbing spring 7 is installed between the lower surface of the adjusting block 8 and the inner wall of the fixed cylinder 5. The tops of the four movable cylinders 6 are fixedly connected to the lower surface of the mounting plate 2 by bolts. The bottom sealing of the movable cylinder 6 is slidably set inside the fixed cylinder 5. The bottom of the four fixed cylinders 5 is fixedly connected to the upper surface of the base 1 by bolts. A shock-absorbing airbag 11 is set between the middle position of the lower surface of the mounting plate 2 and the upper surface of the base 1. An air suction pipe 14 is fixedly opened on the right side of the shock-absorbing airbag 11. Annular sealing airbags 12 are set on the opposite side and the right connection port of the two sealed protective shells 4. The three annular sealing airbags 12 are connected to the shock-absorbing airbags 11 by a connecting hose 13. An exhaust valve 9 is fixedly opened on the side of each of the three annular sealing airbags 12. A one-way valve 15 is installed inside the connecting hose 13 and the air suction pipe 14.

[0022] In one embodiment of the present invention, the pump body 3 vibrates during operation. The movable cylinder 6 reciprocates within the fixed cylinder 5, compressing the damping spring 7. Through the elastic deformation of the damping spring 7, the vibration energy of the pump body 3 can be initially absorbed and buffered, weakening the impact of vibration on the main body of the equipment. At the same time, through the compression and expansion of the gas inside the damping airbag 11, the vibration energy is further absorbed and dissipated, forming a composite damping system of spring and airbag with the damping spring 7, which greatly improves the damping effect, reduces the vibration amplitude and noise of the equipment. When the damping airbag 11 is compressed, the internal gas is squeezed out and transported through the connecting hose 13 to three annular sealing airbags 12 evenly distributed around the circumference of the sealing protective shell 4. As the gas continues to fill in, the annular sealing airbags 12 emit gas. The self-adaptive expansion mechanism fits tightly between the outer wall of the water pipe and the inner wall of the sealing protective shell 4, dynamically increasing the sealing contact area and clamping force. This forms a sealing structure that becomes increasingly reliable with vibration, effectively preventing the widening of the sealing gap and media leakage caused by vibration and displacement. Furthermore, the sealing protective shell 4 completely encloses the connecting bolts within the sealed cavity, effectively isolating them from contact with the external humid and corrosive environment, preventing the connecting bolts from jamming due to rust, and ensuring the convenience of disassembly and maintenance of the equipment in the future. At the same time, the synergistic effect of the sealing protective shell 4 and the annular sealing airbag 12 can prevent corrosive media from entering the connection parts, eliminating safety hazards such as equipment loosening and falling off caused by connecting bolt failure, and improving the reliability and service life of the device.

[0023] An adaptive vibration damping adjustment assembly is provided on the upper surface of the base 1, the mounting plate 2, and the interior of the movable cylinder 6. The adaptive vibration damping adjustment assembly includes an arc-shaped plate 1001, which is fixedly connected to the right side of the upper surface of the base 1. An inclined guide groove 1002 is provided on the left side of the arc-shaped plate 1001, and a guide pin 1003 is fixedly connected to the right side of the inclined guide groove 1002. A drive internal gear ring 1005 is rotatably connected inside the mounting plate 2, and a first threaded rod 1007 is connected to the inner side of the drive internal gear ring 1005 via an equal-angle bearing inside the mounting plate 2. Four first threaded rods 1007 are also present. The upper outer side of the 07 is fitted with a first driven gear 1004, the right end of the guide pin 1003 is inserted and slidably disposed inside the inclined guide groove 1002, the drive internal gear ring 1005 is meshed with the four first driven gears 1004, and the lower outer side of the four first threaded rods 1007 is fitted with a first threaded cylinder 1006, the lower end of the first threaded rod 1007 extends into the interior of the movable cylinder 6, and the first threaded rod 1007 and the first threaded cylinder 1006 are threadedly connected, and the bottom of the first threaded cylinder 1006 is fixedly connected to the top of the adjusting block 8 by bolts.

[0024] In one embodiment of the present invention, when the internal gear ring 1005 moves up and down with the movable cylinder 6, the guide pin 1003 slides along the inner wall of the inclined guide groove 1002. Under the constraint of the inclined guide groove 1002, the internal gear ring 1005 moves axially and rotates circumferentially. The greater the vibration amplitude, the longer the axial movement of the internal gear ring 1005, and the longer the sliding distance of the guide pin 1003 in the inclined guide groove 1002. Therefore, the larger the circumferential rotation angle generated by the internal gear ring 1005, the greater the vibration amplitude is achieved. The adaptive linkage between degree and rotation angle, and when the internal gear ring 1005 rotates, it drives the four first driven gears 1004 meshing with it to rotate synchronously, thereby driving the four first threaded rods 1007 to rotate; the first threaded rods 1007 are threadedly engaged with the first threaded cylinder 1006, causing the first threaded cylinder 1006 to move up and down along the axial direction, and by adjusting the block 8 to stretch or compress the damping spring 7, the damping resistance can be adaptively adjusted according to the vibration amplitude of the water pump body 3, effectively suppressing excessive amplitude and improving damping stability and equipment operation reliability.

[0025] A vibration-adaptive sealing adjustment assembly is provided between the interior of the base 1 and the lower surface of the mounting plate 2. This assembly includes a slider 1601, which is slidably connected to a groove on the left side of the upper surface of the base 1. A wedge 1603 is fixedly connected to the right side of the slider 1601, and a return spring 1602 is installed between the lower right side of the slider 1601 and the inner wall of the groove. A lifting plate 1608 is bolted to the left side of the lower surface of the mounting plate 2, and a contact block 1607 is rotatably connected to the bottom of the lifting plate 1608 via a shaft. A linkage block 1609 is slidably connected to the upper surface of the contact block 1607. The left side of the slider 1601 is fixedly connected to the right side of the sealing protective shell 4 by bolts. The wedge 1603 and the lifting plate 1608 are positioned relative to each other. The inclined surfaces of the wedge block 1603 and the linkage block 1609 are in contact. The top of the inner wall of the lifting plate 1608 is connected to the second threaded rod 1605. The outer side of the lower end of the second threaded rod 1605 is fitted with a second threaded cylinder 1606. The outer side of the upper end of the second threaded rod 1605 is fitted with and fixed with a second driven gear 1604. The upper end of the second threaded rod 1605 extends into the interior of the mounting plate 2. The second threaded rod 1605 is connected to the mounting plate 2 and the lifting plate 1608 by a bearing. The second driven gear 1604 is meshed with the drive internal gear ring 1005. The second threaded cylinder 1606 is threaded to the second threaded rod 1605. The bottom of the second threaded cylinder 1606 is hinged to the top of the linkage block 1609.

[0026] In one embodiment of the present invention, when the water pump body 3 vibrates during operation, the vibration drives the lifting plate 1608 and the contact block 1607 to move up and down reciprocally. During the downward movement, the lifting plate 1608 and the contact block 1607 continuously press against the inclined surface of the wedge block 1603, pushing the wedge block 1603 to move horizontally. The wedge block 1603 then drives the sealing protective shell 4 to move synchronously. When the lifting plate 1608 and the contact block 1607 move upward and no longer press against the wedge block 1603, the slider 1601 moves back under the elastic reset action of the return spring 1602, and drives the sealing protective shell 4 to reset synchronously. Under the continuous vibration of the water pump body 3, the above actions are performed cyclically, so that the sealing protective shell 4 always follows the wedge block 1603 in reciprocating left and right movements, with a movement frequency similar to that of the water pump body. 3. Maintaining synchronous vibration frequency ensures that the sealing protective shell 4 always maintains a suitable relative position with components such as water pipes and connecting bolts. Combined with the sealing effect of the annular sealing airbag 12, it can effectively compensate for the displacement deviation caused by the vibration of the water pump body 3, further improving the sealing reliability. When the drive internal gear ring 1005 rotates, it can drive the meshing second driven gear 1604 to rotate, causing the second threaded cylinder 1606 to move up and down, and causing the contact block 1607 to deflect, thereby adjusting the tilt angle of the contact block 1607. When the tilt angle of the contact block 1607 increases, its squeezing and pushing stroke on the wedge block 1603 increases accordingly, so that the displacement of the sealing protective shell 4 can be adapted and matched with the vibration amplitude of the water pump body 3, improving the synergistic effect of vibration reduction and sealing.

[0027] Working principle: When using this high-pressure water pump protection device, when the water pump body 3 vibrates during operation, the movable cylinder 6 reciprocates within the fixed cylinder 5, compressing the shock-absorbing spring 7 to achieve initial buffering; at the same time, the shock-absorbing airbag 11 compresses and expands with the vibration, forming a composite shock absorption with the spring, significantly reducing vibration and noise. Furthermore, the exhaust from the shock-absorbing airbag 11 is sent to the annular sealing airbag 12 through the connecting hose 13, causing it to expand and seal, preventing media leakage; the sealing protective shell 4 wraps around the connecting bolts, isolating corrosion, preventing bolt jamming, and improving equipment sealing and maintenance convenience; when the movable cylinder 6 drives the drive internal gear ring 1005 to move downward, the guide pin 1003 slides along the inclined guide groove 1002, driving the drive internal gear ring 1005 to rotate, with a larger amplitude and a larger rotation angle. The internal gear ring 1005 drives the first driven gear 1004 and the first threaded rod 1007 to rotate, which in turn drives the first threaded cylinder 1006 to drive the adjusting block 8, adaptively changing the force on the damping spring 7, suppressing excessive amplitude, and improving damping stability. The vibration of the water pump body 3 drives the lifting plate 1608 and the contact block 1607 to reciprocate. When moving downward, the squeezing wedge 1603 pushes the sealing protective shell 4 to move. When moving upward, the reset spring 1602 drives it to reset, realizing that the sealing protective shell 4 moves synchronously with the vibration and compensates for displacement deviation. The internal gear ring 1005 drives the second driven gear 1604 and the second threaded cylinder 1606 to move synchronously, adjusting the tilt angle of the contact block 1607, further adapting to the vibration amplitude, and enhancing the synergistic effect of vibration damping and sealing.
