Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of high-pressure water flow cracking, and particularly relates to a portable energy storage pulse high-pressure water flow cracking device. BACKGROUND

[0002] With the rapid development of the construction industry, the task of demolishing old buildings is becoming increasingly heavy. Traditional demolition methods rely heavily on heavy mechanical equipment (such as hydraulic breakers, etc.), which can handle hard objects such as cement and concrete, but have problems such as large size, heavy weight, and lack of flexibility in operation, making it difficult to adapt to narrow or complex site environments. In addition, such equipment usually relies heavily on electricity, and its use is limited in places where there is no fixed power supply.

[0003] Portable water jet equipment, as a new technology, uses high-pressure water flow for cutting and has been widely used in the fields of pipe cutting and metal plate cutting. However, existing portable water jet systems are mainly designed for material cutting, not cracking, which makes them unable to achieve ideal results when dealing with hard objects such as cement and concrete. This is because the nozzle design of existing water jet systems is mainly for cutting, not cracking, which makes them less efficient when dealing with materials with high hardness and unable to meet the needs of rapid demolition.

[0004] In addition to cutting, the need for cracking of cement and concrete is growing in the fields of building demolition and infrastructure maintenance. Existing portable equipment mostly focuses on cutting functions, and the design of cracking functions is still significantly insufficient, and there is still a lack of portable equipment optimized for cement and concrete cracking conditions, especially for environments that require rapid on-site operations, which require equipment with portability and high cracking efficiency. Although there are some hydraulic breakers or electric tools on the market that can complete the demolition task, they are mostly large in size, complex in operation, and poor in environmental adaptability.

[0005] Therefore, it is necessary to provide a new type of portable energy storage pulse hydraulic cracking device for efficiently cracking hard materials such as cement and concrete without relying on fixed power supply. The device should have the characteristics of miniaturization, strong portability, and wide adaptability, and be able to meet the needs of different on-site demolition operations. SUMMARY

[0006] In view of this, and to address the key problems of existing technologies in demolishing or cracking hard objects (such as cement, concrete, and bricks), such as poor portability, difficulty in on-site power supply, low cracking efficiency, and limited applicability, the present invention aims to provide a portable energy-storing pulsed high-pressure water jet cracking device. The device is compact, vehicle-mountable, and can output high-density pulsed high-pressure water jets to efficiently crack cement, concrete, and other hard objects without the need for a fixed power source. It is particularly suitable for applications such as building demolition, repair and cleaning, and on-site emergency operations.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A portable energy-storing pulsed high-pressure water flow pyrolysis device, comprising:

[0009] Water supply pipelines, including main pipelines and branch pipelines;

[0010] A booster unit is installed on the main pipeline of the water supply pipeline, including a high-pressure water pump, a pulsation attenuator, and at least two boosters connected in parallel between the two, so that the water supplied by the high-pressure water pump is pressurized by the at least two boosters and then mixed with the pulsation attenuator.

[0011] A pulse jet unit is installed on a branch pipe of the water supply pipeline, including an energy storage chamber, a linear solenoid valve and a nozzle array. The inlet of the energy storage chamber is connected to the outlet of the pulsation attenuator. The linear solenoid valve is configured to open and close to control the connection between the outlet of the energy storage chamber and the nozzle array. The nozzle array includes multiple jet nozzles arranged in a preset three-dimensional spatial structure.

[0012] The control system is electrically connected to the pressurization unit and the pulse jet unit, and is configured to at least output a trigger control signal to the linear solenoid valve to control the linear solenoid valve to open and close the connection between the energy storage chamber outlet and the nozzle array according to a preset pulse mode.

[0013] Preferably, a check valve to prevent backflow is provided on the main water supply pipeline for parallel installation of the booster; the inlet of the energy storage chamber is connected to the outlet of the pulsation attenuator via a one-way valve.

[0014] Preferably, the portable energy storage pulse high-pressure water flow pyrolysis device further includes a filter, which is installed on the main pipeline of the water supply line and connected to the inlet of the high-pressure water pump.

[0015] Preferably, the portable energy-accumulating pulse high-pressure water flow lysis device further comprises a pressure relief buffer mechanism for supporting and mounting the nozzle array, which elastically buffers the reaction force generated by the nozzle array and acting on the branch pipeline when the nozzle array is in communication with the water outlet of the energy-accumulating cavity.

[0016] Preferably, the pressure relief buffer mechanism comprises a fixed seat, a sliding seat slidingly assembled on the fixed seat along a set moving direction, and a spring for applying an elastic force to the sliding seat against the moving direction, the sliding seat having a pressure maintaining position for closing the pressure relief buffer mechanism and a pressure relief position for opening the pressure relief buffer mechanism by intensifying the compression of the spring in its moving stroke.

[0017] Preferably, the pressure relief buffer mechanism further comprises an adjusting member mounted on the fixed seat and connected with the spring, the adjusting member comprising a spring seat slidingly assembled on the fixed seat and an adjusting screw for driving the spring seat to reciprocally slide along the moving direction of the fixed seat, the spring being connected between the spring seat and the sliding seat.

[0018] Preferably, the nozzle array is arranged with a plurality of jet nozzle arrays, and a preset shunt spacing is provided between adjacent jet nozzles.

[0019] Preferably, the portable energy-accumulating pulse high-pressure water flow lysis device further comprises a mobile trolley for mounting the pressure boosting unit, the pulse jet flow unit and the control system, the mobile trolley being provided with a radiator for guiding the heat inside the mobile trolley to dissipate outward.

[0020] Preferably, the portable energy-accumulating pulse high-pressure water flow lysis device further comprises a power supply member comprising at least a voltage and current conversion and stabilization module and an overload protection module, for providing stable electric energy with adaptive working voltage and current to the pressure boosting unit, the pulse jet flow unit and the control system.

[0021] Preferably, the power supply member adopts an external vehicle-mounted power supply and is electrically connected with the pressure boosting unit, the pulse jet flow unit and the control system through a power supply interface and a power supply line.

[0022] In summary, the present application adopts a scattering array nozzle structure to replace the traditional single nozzle, which can realize multi-point and high-density impact pulse water jet output. In order to improve the cracking capacity, the energy storage type pulse design is adopted: the vehicle-mounted power drives the high-pressure water pump to pressurize the water into the energy storage cavity, and the linear electromagnetic valve is used as a high-speed opening and closing executive element, and the driving current is controlled by a high-precision PWM signal to drive the slide to realize millisecond level starting operation, so that the high-pressure water in the energy storage cavity is released instantaneously, and multiple time and space distributed pulse action points are formed through the nozzle array, and the target structure surface or internal is acted on efficiently. In the cracking process, the pulse high-pressure water jet is impacted by the instantaneous high-pressure impact, and the water flow kinetic energy and pressure are concentrated on the surface or internal crack of the target object, and the structure cracking is realized by means of water hammer effect, shock wave propagation and pulse repeated loading mechanism, instead of relying on the continuous cutting or flushing of the traditional water jet. The present application can balance the cracking efficiency, energy consumption, safety and environmental adaptability, so as to realize performance optimization in different demolition tasks.

[0023] In order to further inhibit the peak value of the reaction force generated by the nozzle array on the water supply pipeline when the energy storage pulse water jet is released instantaneously, a spring pre-tightening type pressure relief buffer mechanism is arranged on the branch pipeline between the water outlet end of the energy storage cavity and the nozzle array. The pressure relief buffer mechanism provides controllable elastic support for the nozzle array through the pre-tightening spring, keeps the nozzle position stable under normal working pressure and conventional load, and allows the nozzle support to produce limited elastic displacement when the reaction force generated by pulse injection exceeds the preset threshold, so as to convert part of the impact energy into elastic potential energy of the spring and gradually release it after injection, realizing peak cutting and buffering of the impact force.

[0024] The present application has compact structure and is modular, which is convenient for carrying and vehicle-mounted operation, and is especially suitable for diversified demolition, cracking and emergency scenes. Since it can be directly connected with the vehicle-mounted power supply and work without relying on external power grid, independent operation can be realized, so that in remote and power inconvenient construction conditions, high cracking capacity and flexible applicability can still be maintained.

[0025] The high-pressure water flow cracking mechanism on which the present application is based. When the high-pressure water jet is sprayed from the nozzle and impacts on the surface of porous and heterogeneous structure materials such as concrete or cement, the water flow first enters the crack and pore interface of the material, forming a local high-pressure area. At these interfaces, water pressure can induce water wedge effect or similar water hammer effect, that is, the inertial impact and fluid pressure action of pulse water jet will produce instantaneous high-pressure impact, so as to cause tension, shear stress and pressure stress concentration in the solid. When the local stress exceeds the tensile strength or interface bonding strength of the material, crack initiation will occur.

[0026] From the perspective of mechanical flow, the impact of water jet can be simplified and estimated. Let the water flow density at the nozzle outlet be , the water flow volume flow be , and the jet velocity be When the jet beam is completely reflected (i.e., the jet direction changes by approximately 180 degrees), its impact force on the target surface per unit time is... Approximately: ;

[0027] Theoretically, the impact force on a rigid target surface when a high-pressure water jet completely stops or is reflected is... It can be calculated using an ideal model; however, in actual engineering, factors such as the distance between the nozzle and the target surface, fluid turbulence diffusion, and atomization require the introduction of a corrected theoretical value of the efficiency correction coefficient η (0 < η ≤ 1) to approximate the actual impact effect. The actual average impact force is estimated as follows: The value of η can be determined by experimental measurements under similar conditions, or by conservative estimation based on the characteristics of the target material.

[0028] Concrete and other porous, heterogeneous materials are composed of mortar, aggregates, and interfacial transition zones. After crack initiation, they often propagate along the interfaces and pore pathways, forming a complex crack network. This invention employs a fixed array of multi-nozzle, multi-directional pulsed water jets, causing multiple high-pressure impact points to act simultaneously or in short sequences on the same target area. This creates multiple crack initiation points within the material and promotes the interconnection of these cracks under the influence of water hammer pressure and water wedge effect, accelerating crack propagation and convergence. As the pulsed jetting continues, the local crushing zone gradually expands outward, the crack network continues to develop, and ultimately a through-cut surface is formed on the component cross-section, causing large sections of concrete or cement structures to peel off, fragment, or detach entirely, thus achieving highly efficient pyrolysis.

[0029] Compared to traditional continuous water jets, the energy-storing pulsed water jets employed in this invention can generate higher peak impact pressures with each release, while reducing the water cushion effect easily formed in continuous jets. This makes it easier to induce crack initiation and promote rapid crack propagation within porous materials such as concrete. Combined with the multi-nozzle array structure used in this invention, the effective area and number of impact points of the pulsed water jet are significantly increased, improving both the crack initiation probability and crack connection speed. Therefore, the cracking efficiency of this invention in thick components, porous, and heterogeneous materials is significantly superior to traditional methods using single-nozzle, continuous jets.

It should be understood that such data can be interchanged under appropriate circumstances, so as to describe the embodiments of the present application.

[0039] As Figure 1As shown, the portable energy storage pulse high-pressure water flow cracking device of the present application comprises a mobile trolley 10 with an overall outer shape of a cuboid structure. The mobile trolley 10 is provided with four wheels at the bottom, two small wheels at the front and two large wheels at the rear, forming stable mobile support for easy movement. The top front end of the mobile trolley 10 extends obliquely to form a handle, facilitating the user to push and pull for control. The rear end surface is distributed with multiple parallel stripe-shaped structures, i.e. a plate-type radiator 11, for conducting heat generated during device operation. The overall design takes into account the convenience of movement and the functionality of practicality, with the core structure clearly presented.

[0040] In this embodiment, the top front end of the outer box extends forward and upward as a whole to form a handle, which is rigidly connected with the outer box and held by the operator to realize the pushing, steering and traction movement of the device, so that the movement and positioning of the device can be completed on site without additional handling tools. The rear end surface of the outer box is provided with parallel stripe-shaped structures, which constitute ventilation and heat dissipation windows or heat dissipation ribs, for conducting heat generated by the internal pressure increasing unit and control system 12 to keep the internal temperature within a safe range and prevent the performance of the elements from being degraded or damaged due to overheating. Through the cooperation design of the mobile trolley 10 and the handle, the device has the characteristics of compact structure, easy movement, and is suitable for vehicle-mounted and on-site rapid deployment, while ensuring the reasonable arrangement and protection of the internal functional modules.

[0041] As shown in the drawings, Figure 2As shown, the portable energy storage pulse high-pressure water flow cracking device of the present application comprises a main pipeline 19 of a water supply pipeline and a booster unit arranged on the main pipeline 19 of the water supply pipeline. Specifically, the booster unit comprises a high-pressure water pump 14, a pulse attenuator 18, and at least two boosters 17 connected in parallel between the two, and each of the boosters 17 is provided with a check valve 16. In addition, the front end of the main pipeline 19 of the water supply pipeline is also connected with a filter 15, and the end of the main pipeline 19 of the water supply pipeline is also connected with a branch pipeline 23 provided with a pulse jet unit. The water source flows into the filter 15 through the water inlet, and the impurities are intercepted by the filter screen, preventing the subsequent high-pressure water pump 14 or jet nozzle 26 from being blocked and worn, and ensuring the stable operation of the overall device; the filtered clean water is sucked by the high-pressure water pump 14 and pressurized to the booster 17, and further pressurized to the required pressure grade of the jet; at least two boosters 17 are connected in parallel to quickly complete the jet increase through parallel shunt-mixed flow; and each of the boosters 17 is provided with a check valve 16 to prevent pressure echo or backflow from damaging the pump body, sealing element and water supply pipeline through one-way flow limiting; then the water flow enters the pulse attenuator 18, absorbs the pressure pulsation and water hammer impact through the buffer cavity, stabilizes the water pressure before spraying, ensures that the water jet pressure before entering the pulse jet unit is uniform and has good continuity, and prolongs the service life of components such as the high-pressure water pump 14 and the jet nozzle 26; finally, the high-pressure water is sent to the pulse jet unit through the branch pipeline 23 to impact hard materials such as concrete and masonry in the form of pulse water jet to realize cracking.

[0042] In the embodiment, the booster unit is provided with control instructions and power supply through the control system 12 and the power supply part 13. The power supply part 13 preferably adopts an external vehicle-mounted power supply and is electrically connected with the booster unit, the pulse jet unit and the control system 12 through a power supply interface and a power supply line. Specifically, the power supply part (vehicle-mounted power supply) at least comprises a voltage and current conversion and voltage stabilizing module, and an overload protection module (including overcurrent, overvoltage, short circuit protection and power-off switch); the vehicle-mounted power supply power is converted by the voltage and current conversion and voltage stabilizing module to provide stable power with adaptive working voltage and current for the high-pressure water pump 14, which can meet the high-power starting demand and continuous operation stability of the high-pressure water pump 14, and automatically power off for protection when voltage is abnormal, overloaded or connected with a fault, realizing vehicle-mounted mobile independent power supply without external power grid and ensuring safe and reliable operation of the device.

[0043] In addition, the portable energy storage pulse high-pressure water flow cracking device of the present application adopts a direct external water supply mode, without the need for a built-in large water storage tank, thereby avoiding the burden brought by the fixed water tank in terms of volume, weight and maintenance. Specifically, the high-pressure water pump 14 is supplied with water from an external on-site water source or a portable mobile water storage unit, which is pumped in and pressurized and then delivered to the energy storage chamber 21 for energy storage. This design makes the overall device structure more compact and portable, facilitating installation on a small trolley body or a vehicle-mounted bracket, realizing portable transportation and on-site rapid deployment, and meeting the requirements of water source adaptability in various operating environments.

[0044] To further ensure the safety and stability of the operation of the pressure boosting unit, the operator should check and confirm the connection of the main components before starting the pressure boosting unit. Before implementation, first transport the mobile trolley 10 to the construction site and place it on a stable and sufficiently load-bearing ground, then connect the vehicle-mounted power supply to the high-pressure water pump 14, and confirm that the power supply voltage and current meet the device operation requirements. Then, connect the external water supply to the water inlet of the high-pressure water pump 14 through the water supply interface, ensure that the water source connection is firm and the water supply is stable, and confirm that the filter 15 screen is in an unobstructed state.

[0045] As shown in Figure 3 and Figure 4 , the portable energy storage pulse high-pressure water flow cracking device of the present application includes a branch pipe 23 of the water supply pipeline and a pulse jet unit arranged on the branch pipe 23 of the water supply pipeline. Specifically, the pulse jet unit includes a check valve 25, an energy storage chamber 21, a linear electromagnetic valve 20, a pressure relief buffer mechanism 22 and a nozzle array 24, the water inlet of the energy storage chamber 21 is connected to the water outlet of the pulsation attenuator 18 through the check valve 25, the linear electromagnetic valve 20 is configured to control the communication between the water outlet of the energy storage chamber 21 and the nozzle array 24, the nozzle array 24 includes a plurality of jet nozzles 26 arranged in a predetermined three-dimensional space structure; the plurality of jet nozzles 26 of the nozzle array 24 are arranged in an array as shown in Figure 4 , and a predetermined shunt spacing is provided between adjacent jet nozzles 26. The jet nozzles 26 outlets are gem nozzle holes, high-pressure water from the energy storage chamber 21 is rushed to the nozzle array 24 after passing through the linear electromagnetic valve 20, and high-pressure water jets are sprayed in a pulse manner, implementing multi-point, multi-directional and high-density impact on the target hard material.

[0046] As shown in Figure 4As shown, the outlet diameter, direction and spacing of the multiple jet nozzles 26 of the nozzle array 24 are designed to ensure that the pulse water jet reaches the target surface and all jet nozzles 26 output the high-pressure water jet pulse group synchronously. The array is designed with uniform distribution and reasonable spacing, so that the water jet pulse group achieves wider coverage, more impact points and higher impact density on the target surface, thereby solving the problems of low cracking efficiency, small action area and uneven fragmentation caused by the dependence on a single impact point of the traditional single nozzle.

[0047] In this embodiment, the nozzle array 24 structure has obvious advantages. First, if the number of jet nozzles 26 is n, the total impact energy or impact force of the array can be approximately the sum of the impact energy of each nozzle That is, the increase in the number of jet nozzles 26 can linearly (or nearly linearly) improve the overall impact effect and enhance the cracking ability. Second, the nozzle array 24 greatly expands the water jet action area. If the influence area of each jet nozzle 26 is , then the influence area of the nozzle array 24 is , which changes the single-point impact on the target surface to multi-point wide-area impact, improves the cracking efficiency and fragmentation uniformity, and reduces the risk of local wear caused by excessive energy concentration of a single nozzle. In addition, compared with the traditional single nozzle continuous impact, the multi-nozzle array pulse water jet of the present application disperses the impact points in space and superimposes the pulse impact in time, which weakens the water cushion effect and energy loss caused by the rebound flow at the single impact point, so that the jet beam group maintains high pressure and high kinetic energy characteristics while improving energy utilization efficiency and cracking effect. Specifically, the outlet diameter, jet angle and spacing between nozzles of the jet nozzles 26 are determined according to typical concrete strength grade, target cracking depth and working distance, etc. in the design stage, and are fixed during assembly, and are not adjusted during on-site use. By using fixed array arrangement and preset spacing, the pulse water jets form a stable and highly repeatable multi-point impact distribution on the target surface, which is convenient for manufacturing and maintenance, and is also conducive to obtaining stable and reliable cracking effect.

[0048] In this embodiment, the spraying operation process is as follows: the control system 12 first controls the booster unit to pump and pressurize water, and the high-pressure water flows into the energy storage cavity 21 through the one-way valve 25 at the water outlet of the pulse attenuator 18 for energy storage (the one-way valve 25 prevents reverse flow). When the storage water pressure reaches the preset value, the operator sends a "spraying start signal" by pressing the spraying trigger button of the nozzle array 24, and the linear electromagnetic valve 20 is quickly opened. The high-pressure water in the energy storage cavity 21 flows out along the high-pressure main water path. Since the nozzle array 24 instantaneously releases high-pressure water, peak pressure and reaction force are generated in the front cavity of the jet nozzle 26 and the branch pipe 23. When the pipe pressure exceeds the preset pressure relief pressure, the pressure relief buffer mechanism 22 automatically opens the pressure relief passage to offset the reaction force and protect the system. The main flow is guided to multiple jet nozzles 26 through the branch pipe 23, and is sprayed out of the nozzle hole at high speed to form a high-peak pulsed high-pressure water jet, which impacts the target object surface in a multi-point, multi-direction, and high-density manner. After spraying is completed, the control system 12 closes the linear electromagnetic valve 20, the high-pressure water path pressure drops, the pressure relief buffer mechanism 22 automatically resets and closes, and the system enters the next energy storage cycle or stops. During the whole spraying process, the operator can monitor the water pressure, water flow, booster unit and pulse jet unit through the control panel, and stop spraying and close the high-pressure water pump 14 in time if an abnormality is detected. After the cracking task is completed, the linear electromagnetic valve 20 is closed, the high-pressure water pump 14 is stopped after the pressure in the water supply pipe drops to a safe range, the power supply and water supply connection are finally disconnected, and the water supply pipe, booster unit and pulse jet unit are cleaned and inspected for subsequent use. Through the above preparation, start, spraying, monitoring, closing and maintenance process, the device can realize safe, reliable and efficient high-pressure water flow cracking operation on site, while ensuring stable equipment performance, safe use, clean environment, and flexible use by the operator under different site conditions.

[0049] In this embodiment, in order to realize millisecond, high-peak, cluster impact pulsed high-pressure water jet, the pulse jet unit adopts a structure form of energy storage cavity 21 and linear electromagnetic valve 20: the booster unit first charges and pressurizes the energy storage cavity 21, and when the pressure in the energy storage cavity 21 reaches the preset energy storage pressure, a trigger signal is sent to the control system 12 through the spraying trigger button, and the control system 12 drives the linear electromagnetic valve 20 to quickly open in milliseconds to instantaneously release the high-pressure water in the energy storage cavity 21, and the pulsed water jet is sprayed out through the branch pipe 23 and the nozzle array 24. Compared with the continuous spraying mode, the energy storage type pulse spraying can obtain higher peak pressure and impact energy density in a single spraying moment, and the multiple nozzle array structure is used to make multiple high-pulse water jets act on the target structure synchronously, thereby significantly improving the cracking efficiency of hard materials.

[0050] As Figure 6As shown in the use state diagram of the present application, the impact and cracking mechanism between the high-pressure water jet and the target body is illustrated. The high-pressure water is delivered to the nozzle array 24 of the pulse jet unit through the booster unit and the water supply pipeline, and then ejected from the outlet at an initial speed The high-speed water jet "flow core" area is formed by the sudden ejection from the outlet, forming an elongated cluster. The water jet beam impacts the target surface (cement member) with extremely high kinetic energy, and the impact instantaneously generates a large momentum transfer and pressure effect on the target surface. The impact force is proportional to the water flow and the ejection speed. In order to monitor the pressure state in real time during the ejection process, a pressure gauge is provided on the main pipeline 19 where the booster unit is installed, which is used to display the actual working pressure of the booster unit and feedback to the control system 12 or the on-site operator. When the pressure approaches or exceeds the preset safety threshold, an alarm or protection measure can be triggered to avoid overpressure damage to the equipment. The high-speed high-pressure water jet (in this application, it is an energy storage type pulse water jet) forms a transient high-pressure "water hammer" effect on the target surface and its near-nozzle area. With repeated impact of the pulse water jet, cracks gradually emerge, expand and connect with each other under the combined action of shock wave superposition, fluid penetration and water wedge effect, and finally form a clear cracking zone or peeling area. When the cracks are connected inside the material and the local stress exceeds the component strength threshold, the target structure appears to be peeled off, broken or cracked, achieving the purpose of cracking.

[0051] As shown in the use state diagram of the present application, the impact and cracking mechanism between the high-pressure water jet and the target body is illustrated. The high-pressure water is delivered to the nozzle array 24 of the pulse jet unit through the booster unit and the water supply pipeline, and then ejected from the outlet at an initial speed Figure 5 As shown in the pressure relief buffer mechanism 22 of the present embodiment, the pressure relief buffer mechanism 22 includes a fixed seat 27, a sliding seat 28 slidingly assembled on the fixed seat 27 in a set movement direction, and a spring 29 for applying an elastic force to the sliding seat 28 in the opposite direction of the movement direction. The sliding seat 28 has a pressure maintaining position for closing the pressure relief buffer mechanism 22 and a pressure relief position for opening the pressure relief buffer mechanism 22 by intensifying the compression of the spring 29 in its movement stroke. Specifically, the fixed seat 27 is a hollow cylindrical structure, the fixed seat 27 is rigidly connected with the branch pipeline 23, the sliding seat 28 is arranged at the opening of the fixed seat 27, the nozzle array 24 is installed on the sliding seat 28, and a sealing ring is arranged on the outer periphery of the sliding seat 28 to cooperate with the sliding seat 28 to prevent dust and debris from entering the inside of the fixed seat 27; the spring 29 is installed inside the fixed seat 27 to provide elastic support for the sliding seat 28 and the nozzle array 24.

[0052] In this embodiment, the pressure relief buffer mechanism 22 is used as a counterforce buffer mechanism of the nozzle array 24. Under no spraying or normal load, the pre-tightened spring 29 keeps the slide 28 in the initial position, and the nozzle array 24 is stable. When the pulse high-pressure water flow is released from the accumulator chamber 21, the nozzle generates a larger reverse impact force, which is applied to the spring 29 through the slide 28; when the impact force is below the preset threshold, the spring 29 is only slightly deformed, and the structure is basically not displaced; when the impact force exceeds the preset threshold, the slide 28 moves axially relative to the fixed seat 27, compresses the spring 29, and part of the impact energy is converted into elastic potential energy, thereby reducing the peak reaction force transmitted to the rack. After the pulse ends, the spring 29 releases the elastic potential energy, pushes the slide 28 back to the initial position, and the pressure relief valve is automatically reset, ready for the next energy storage pulse spraying.

[0053] In addition, in order to provide more flexible pressure relief buffering, the pressure relief buffer mechanism 22 further comprises an adjusting member mounted on the fixed seat 27 and connected with the spring 29, the adjusting member comprising a spring seat 30 slidingly assembled on the fixed seat 27 and an adjusting screw 31 for driving the spring seat 30 to reciprocate along the moving direction of the fixed seat 27, and the spring 29 is connected between the spring seat 30 and the slide 28. Based on this, the initial compression amount of the spring 29 can be changed by rotating the adjusting screw 31, so as to set the pre-tightening force and the initial response threshold of the pressure relief buffer mechanism 22.

[0054] In summary, through the above specific embodiments, combined with the high-pressure water pump 14, the nozzle array 24, the modular structure, the vehicle-mounted power supply and the flexible control system, a portable, high-efficiency, high-adaptability energy storage pulse high-pressure water flow cracking device is realized, which can crack hard materials such as concrete, cement, bricks and stones in various field environments.
