Description

Technical Field

[0001] This application relates to the field of pile driver equipment technology, and in particular to a water flow booster connector, a high-pressure water jet and pile driver equipment. Background Technology

[0002] In soil drilling operations, especially when dealing with hard soils such as compacted soils, traditional chain drill bits often suffer from low drilling efficiency. To improve drilling results, existing technologies typically use high-pressure water flow to pre-disperse hard soil. However, the pressure distribution at the outlet of conventional water flow pipelines is uneven, resulting in insufficient water flow impact force and unsatisfactory soil breaking effect. Particularly in operation scenarios where the water flow impact force needs to be adjusted, existing joint structures cannot achieve convenient pressure adjustment, often requiring the replacement of the entire water outlet device, which increases operating costs and affects work efficiency. Furthermore, traditional pressure boosting joints are complex in structure, inconvenient to disassemble and assemble, and cumbersome to operate in conditions where frequent replacement of damping components is required. Utility Model Content

[0003] In view of this, the purpose of this application is to provide a water flow booster connector, a high-pressure water jet and a piling machine to enhance the impact of water flow and to facilitate the replacement of the booster connector.

[0004] To achieve the above objectives, this application provides the following technical solution:

[0005] A water flow booster connector is disposed at the outlet of a water flow pipeline, comprising a connector body and a first damping component. The connector body is assembled into the water flow pipeline and connects the water flow pipeline and the first damping component. The first damping component has a booster channel, which contracts away from the outlet.

[0006] Preferably, the above-mentioned water flow booster connector further includes a second damping element, wherein the contraction rates of the booster channels in the first damping element and the second damping element are different;

[0007] The connector body includes a mounting base with a single connection size, and the first damping member and the second damping member have the same locking part and can both be assembled into the mounting base.

[0008] Preferably, in the above-mentioned water flow booster connector, the mounting base has a mounting hole and an internal thread, at least a portion of the first damping member and the second damping member can be embedded in the mounting hole, and the areas of the first damping member and the second damping member embedded in the mounting hole have external threads that mate with the internal thread.

[0009] Preferably, the above-mentioned water flow booster connector further includes a connecting sleeve, which is assembled and connected to the connector body, and the connecting sleeve and the connector body are locked together at both ends along the axial direction of the booster channel to secure the first damping element.

[0010] Preferably, in the above-mentioned water flow booster connector, both the connecting sleeve and the first damping element are fully embedded in the connector body.

[0011] Preferably, in the above-mentioned water flow booster connector, the booster channel continuously contracts from the second end to the first end, the second end being the end closer to the water flow pipeline than the first end; and within the booster channel, the wall connecting the second end and the first end is a continuous inclined surface or a continuous arc surface.

[0012] Preferably, in the above-mentioned water flow booster connector, the first end has a strip-shaped opening structure.

[0013] Preferably, in the above-mentioned water flow booster connector, the first damping element is an integral piece and integrally formed with the booster channel, or the first damping element is a spliced ​​structure, and the splice seam of the first damping element bisects the first end along the length direction of the strip opening at the first end.

[0014] Preferably, in the above-mentioned water flow booster connector, the first damping element includes a first splicing layer and a second splicing layer that are spliced ​​and fixed together, and the first splicing layer and the second splicing layer are arranged along the length direction of the booster channel; the constriction section of the booster channel passes through the first splicing layer and the second splicing layer.

[0031] The core of this application is to disclose a water flow booster connector, a high-pressure water jet and a piling machine, so as to enhance the impact of water flow and realize the convenient replacement of the booster connector.

[0032] To enable those skilled in the art to better understand the present application, embodiments of the present application will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model described in the claims. Additionally, the complete content of the structures represented in the following embodiments is not limited to those necessary for the solution of the utility model described in the claims.

[0033] like Figure 1 and Figure 2 As shown in the figure, this embodiment of the present disclosure provides a water flow booster connector, which is installed at the outlet of the water flow pipeline to guide and boost the water flow, thereby dispersing hard soil and reducing drilling difficulty.

[0034] Specifically, the water flow booster connector includes a connector body 10 and a first damping element 20. The connector body 10 is assembled into the water flow pipeline and connects the pipeline with the first damping element 20, serving as a transition structure connecting the water flow pipeline and the first damping element 20. Specifically, it can be made of metal or engineering plastic into a tubular shell, with one end fixed to the outlet of the water flow pipeline by threads or clips to achieve assembly with the water flow pipeline, and the other end assembled and connected to the water flow pipeline. Therefore, it is preferable that the connector body 10 and the first damping element 20 are separate structures. When maintenance or replacement is required, the connector body 10, as the transition structure, can still remain in the assembled state on the water flow pipeline, and only the first damping element 20 needs to be maintained or replaced, reducing maintenance difficulty and cost.

[0035] And such Figure 2 and Figure 3 As shown, the first damping element 20 is a fluid control component of the pressurization channel 210 with a contraction structure. Specifically, it can adopt a conical or stepped contraction structure, for example, the internal part is machined into a conical through hole with the large end facing the water flow pipe and the small end facing outward, so as to guide the water flow through and generate pressure changes, so that the cross-sectional area of ​​the water flow gradually decreases during the flow process, the flow velocity increases and the dynamic pressure increases, and it is ejected with higher pressure and flow velocity, thereby dispersing the hard soil and reducing the difficulty of subsequent drilling.

[0036] Specifically, after the water flows into the joint body 10 from the pipeline, it is guided to the pressurization channel 210 in the first damping element 20. At the same time, as the channel gradually contracts outward, the cross-sectional area of ​​the water flow continues to decrease, and the flow velocity increases accordingly. The increased flow velocity leads to an increase in dynamic pressure, thereby forming a high-pressure jet at the channel outlet. When this jet impacts the soil, the high-pressure area is concentrated, which can effectively penetrate the compacted soil layer and loosen it, thereby improving drilling efficiency.

[0037] Furthermore, in some embodiments of this disclosure, the water flow booster connector further includes a second damping element. The second damping element is a component with a similar structure to the first damping element 20 but a different contraction rate of the booster channel 210. Specifically, it can be made of the same material as the first damping element 20 but with a different channel cross-sectional contraction gradient to provide differentiated water flow boosting effects. It should be noted that the different contraction rates refer to the different rates of change of the cross-sectional area of ​​the booster channel 210 along the water flow direction. Specifically, this can be achieved by adjusting the tilt angle or curvature of the channel wall to meet the pressure requirements under different working conditions. Based on this, the connector body 10 includes a mounting base 110, which has a single connection size for the installation of the first damping element 20 and the second damping element. The standardized design of the single connection size achieves compatibility between different damping elements. Correspondingly, the first damping element 20 and the second damping element have the same locking part and can both be assembled onto the mounting base 110. In practical use, operators can select damping components with corresponding shrinkage rates according to different soil hardness to improve the versatility of the water flow booster connector.

[0038] In some embodiments of this disclosure, the mounting base 110 has a mounting hole and an internal thread, while the first damping member 20 and the second damping member have external threads that mate with the internal thread, so that the first damping member 20 and the second damping member can be inserted into the mounting hole by rotation.

[0039] Furthermore, in order to improve the assembly stability of the first damping member 20 and the second damping member, in some embodiments, at least a portion of the first damping member 20 and the second damping member can be embedded in the mounting hole for assembly, and the areas on the first damping member 20 and the second damping member with external threads are located in the areas embedded in the mounting hole, so as to protect the threads and reduce the risk of assembly failure.

[0040] Unlike existing technologies, this disclosure utilizes two or more damping components with different shrinkage rates and a standardized mounting base 110 for quick replacement. This maintains structural compactness while significantly improving adaptability. When adjusting the pressurization effect, it eliminates the need for complete replacement of the connector or disassembly and reassembly of the internal structure, as is required in existing technologies, simplifying operation and reducing costs. In some specific embodiments, when encountering compacted soil, a second damping component with a larger shrinkage rate can be selected to generate higher pressure water flow to disperse hard soil layers; in ordinary soil layers, the first damping component 20 with a smaller shrinkage rate is switched to avoid excessive consumption of water pressure resources. The adjustable damping components effectively improve the adaptability of the water flow pressurization connector and drilling equipment to different working conditions, while reducing component replacement costs.

[0041] Furthermore, such as Figure 4 and Figure 5 As shown, in some embodiments of this disclosure, the water flow booster connector further includes a connecting sleeve 30. Specifically, the connecting sleeve 30 is assembled and connected with the connector body 10 to form a locking structure for the first damping member 20. Specifically, the assembled connecting sleeve 30 and the connector body 10 can effectively lock the first damping member 20 in the axial direction at both ends of the booster channel 210. In some specific embodiments, the connecting sleeve 30 is an annular structure, which can be made of metal or high-strength plastic, and forms an embedded annular locking structure with the connector body 10. During the assembly of the water flow booster connector, the first damping member 20 can be placed into the connector body 10 first. The connector body 10 and the first damping member 20 are axially engaged through diameter difference or stepped structure. Then, the connecting sleeve 30 is assembled with the connector body 10. The connecting sleeve 30 and the connector body 10 form a locking structure at both ends of the booster channel 210 in the axial direction, so as to press the first damping member 20 from both sides, so that the first damping member 20 is completely fixed between the two, completing the assembly of the water flow booster connector and avoiding the loosening of components caused by water flow impact. Meanwhile, the above structure does not require additional connection to the first damping component 20, reducing assembly damage to the first damping component 20; and during disassembly and maintenance, only the connecting sleeve 30 needs to be removed to take off the first damping component 20, reducing the difficulty of maintenance and replacement of the first damping component 20 in the water flow booster connector.

[0042] Based on the above embodiments, in order to further protect the first damping member 20, in some embodiments, for the structure in which the first damping member 20 is installed by clamping the connecting sleeve 30 and the connector body 10, both the connecting sleeve 30 and the first damping member 20 are completely embedded in the connector body 10, so that the connecting sleeve 30 and the first damping member 20 are completely wrapped by the connector body 10, thereby avoiding damage to the exposed parts by external forces, and simplifying the overall external structural outline to adapt to narrow installation spaces.

[0043] Furthermore, in some embodiments of this disclosure, the pressurization channel 210 disposed in the first damping member 20 has a structure that continuously contracts from its second end 2120 to its first end 2110. It should be noted that the second end 2120 is the end closer to the water flow path than the first end 2110. Specifically, the pressurization channel 210 is the path through which the water flows, and can be implemented using a gradually contracting structure. A pressure gradient is formed by gradually reducing the cross-sectional area of ​​the channel. Continuous contraction means that the cross-sectional area of ​​the channel decreases without interruption along the water flow direction. This can be achieved using a linear or nonlinear contraction curve to avoid the risk of turbulence caused by step-like abrupt changes and to improve the uniformity of the water flow compression process. This can be achieved using a continuous inclined surface or a continuous arc surface structure, so that the interior of the pressurization channel 210 forms a conical inclined surface or a parabolic arc surface, thereby ensuring a stable pressure increase during the water flow acceleration process.

[0044] To further optimize the above technical solution, in some embodiments of this disclosure, the first end 2110 of the pressurization channel 210 is a strip-shaped opening structure, which can be implemented by rectangular, elliptical or other elongated openings. It can be formed by stamping, injection molding or cutting. Its length direction is perpendicular to the contraction direction of the pressurization channel 210, thereby expanding the water flow coverage area when water is discharged and making the water flow form a linear structure and spray out at high speed. Compared with a circular opening, it can cover a larger area of ​​soil surface and make the impact force act evenly on the soil surface layer, which not only improves the soil loosening efficiency per unit time, but also reduces the attenuation of water flow pressure in a single area.

[0045] Through the above technical solution, the water flow booster joint provided in this application can not only form a wide impact surface with high pressure water flow, but also improve the dispersing effect on compacted soil under the same water pressure, thereby reducing subsequent drilling resistance. At the same time, the strip-shaped opening structure can also avoid local soil splashing caused by excessive concentration of water flow in the circular nozzle, reduce water waste, and extend the service life of the joint.

[0046] Furthermore, such as Figure 6 As shown, the first damping component 20 with the strip-shaped opening structure can be a single piece, that is, a structure formed by integral processing of a single material. Specifically, it can be achieved by injection molding or metal casting processes, which can ensure the continuity and structural strength of the pressurization channel 210 and avoid the risk of leakage caused by splicing. Correspondingly, the pressurization channel 210 is a channel structure formed by integral molding. For example, it can be made of corrosion-resistant plastic or metal material and then demolded, so that the inner wall of the channel is smooth and seamless, reducing water flow resistance.

[0047] In some embodiments, such as Figure 7As shown, the first damping component 20 is a spliced ​​structure, that is, the first damping component 20 is a structure assembled from multiple independent parts. In this embodiment, it is assembled from two parts, which allows the first damping component 20 to be processed by a split mold and then fixed by welding or snap-fitting. This facilitates the segmented processing and adjustment of the complex-shaped pressurization channel 210. Correspondingly, when the first damping component 20 adopts a spliced ​​structure, the splice seam of the first damping component 20 is bisected along the length of the strip opening of the first end 2110, so that the two sides of the first damping component 20 can bear the same channel load requirements. Through the symmetrical splicing design, the structural stability is maintained, and the manufacturing flexibility of the complex channel is provided. At the same time, the water flow distribution is optimized by the symmetrical layout of the splice seam.

[0048] Furthermore, in the water flow booster connector provided in the embodiments of this disclosure, such as Figure 8 and Figure 9 As shown, in order to facilitate the adjustment of the water outlet state, the first damping element 20 specifically includes a first splicing layer 220 and a second splicing layer 230 that are spliced ​​and fixed together. Specifically, the first splicing layer 220 and the second splicing layer 230 are arranged along the length direction of the pressurization channel 210, and the contraction section of the pressurization channel 210 passes through the first splicing layer 220 and the second splicing layer 230. It should be noted that the splicing layer refers to the split structural unit constituting the damping element, which can be implemented using an injection-molded independent thin sheet structure. Splicing reduces the manufacturing difficulty of complex curved surface structures. The splicing and fixing refers to the interlayer connection method, which can be achieved by snap-fit ​​or threaded fastening. At the same time, the pressurization channel 210 through means that the through hole of the contraction section spans multiple splicing layers. In some embodiments, the first damping element 20 can adopt a splicing structure of the first splicing layer 220 and the second splicing layer 230. Correspondingly, the pressurization channel 210 has a longer axial extension distance, the water flow has a longer pressurization path, and the output water pressure is greater, which is suitable for soil layers with higher hardness. In other embodiments, the first damping element 20 can only adopt the first splicing layer 220 and remove the second splicing layer 230, so that the pressurization path of the pressurization channel 210 is relatively shortened, the water flow compression path is shortened and there is a larger output volume, which can quickly soften relatively soft soil layers and improve the softening efficiency of the soil layer.

[0049] Based on the above embodiments, in order to further optimize the water flow pattern, such as... Figure 8 and Figure 9As shown, the water flow booster connector also includes a third splicing layer 240. Specifically, the third splicing layer 240 is stacked with the first splicing layer 220 and the second splicing layer 230 along the length of the booster channel 210, and the contraction section of the booster channel 210 penetrates the third splicing layer 240, so that the booster channel 210 forms a three-stage contraction structure. Correspondingly, the booster channel 210 has three different length adjustment methods to achieve three different boosting effects. Operators can select different booster channel 210 structures to adapt to different soil structures. By replacing splicing layers of different sizes, the boosting parameters can be quickly adjusted, realizing the flexible configuration of different contraction rate combinations. This allows for rapid adjustment of the water flow impact force according to soil hardness during drilling operations, improving the versatility of the water flow booster connector.

[0050] Furthermore, this utility model embodiment also provides a high-pressure water jet, which includes a water flow pipeline for supplying water, and the outlet of the water flow pipeline is provided with a water flow booster connector provided in any of the above embodiments. It should be noted that since the water flow booster connector has the above-mentioned technical effects, the high-pressure water jet also has the above-mentioned technical effects, and will not be described again here.

[0051] Furthermore, this embodiment of the invention also provides a piling machine device, which has at least one set of high-pressure water jets provided in the above embodiments. It should be noted that, since the high-pressure water jet has the aforementioned technical effects, the piling machine device also possesses the aforementioned technical effects, and will not be elaborated upon further here.
