Description

Technical Field

[0001] This utility model relates to the field of high-pressure water jet technology, and in particular to a nozzle structure for a perforating water gun. Background Technology

[0002] A perforating water gun is a device that uses the impact force of high-pressure water to complete a task. It plays an important role in many fields. Its working principle is based on kinetic energy conversion. A power system drives a water pump to pressurize the water. The high-pressure water flows through the pipeline and is sprayed out from a special nozzle, impacting the target object at high speed to achieve the functions of perforation, demolition or cleaning.

[0003] A search revealed Chinese patent publication number CN213996926U, which discloses a water gun and its usage method. The water gun includes a housing, a handle, and a pumping module. The housing has a water outlet and a power supply end positioned opposite each other, and a mounting cavity. The handle is located on the outer wall of the housing, between the water outlet and the power supply end, and has a water inlet. The pumping module is located within the mounting cavity, adjacent to the handle, and is used to transport water from the water inlet to the water outlet. This water gun does not have a prominent headweight, making it easy to hold and use. However, in actual use, during drilling operations, a drilling water gun is used to guide high-pressure water flow to impact the soil for drilling. While this water gun achieves drilling by spraying high-pressure water through a single nozzle, its drilling diameter is limited, and it generates a large amount of mud splashing. The splashed mud can clog the nozzle, affecting drilling efficiency and potentially causing injury to surrounding personnel. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nozzle structure for a punching water gun, aiming to improve the problem in the prior art that a large amount of mud splashing is generated, which can cause the nozzle to become clogged and affect the punching efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a nozzle structure for a perforating water gun, including a barrel, an anti-blocking mechanism at the bottom of the barrel for preventing mud from splashing, a positioning plate slidably connected to the outer wall of the barrel, and a guide mechanism at the top of the positioning plate for vertically positioning the barrel. The anti-blocking mechanism includes a nozzle, the top of which is connected to the bottom of the barrel. Multiple expansion vanes are fixedly connected to the outer wall of the nozzle. Multiple guide grooves are opened on the outer wall of each of the multiple expansion vanes. The top of each of the multiple expansion vanes is fixedly connected to the same protective cover. An acceleration component is provided inside the nozzle.

[0006] The above technical solutions include: the expansion wing in the anti-clogging mechanism supports the nozzle, preventing direct contact with the soil and thus preventing blockage; the guide channel guides the splashed mud and water, reducing splashing and lowering the risk of blockage; the protective cover further blocks mud, providing all-around protection for the nozzle; the acceleration component enhances the impact force of the water flow, improving punching efficiency; and the guide mechanism, in conjunction with the positioning plate, ensures that the barrel moves vertically during operation, guaranteeing the accuracy of the hole position. This makes the entire punching operation efficient and stable, reducing rework caused by blockage and hole position deviation, and improving construction quality and efficiency.

[0007] As a further description of the above technical solution: The guiding mechanism includes a bracket, the top of which is fixedly connected to the bottom of the positioning plate. Two clamping plates are slidably connected to the outer wall of the barrel. Two side blocks are fixedly connected to the outer walls of the two clamping plates. Sliding rods are fixedly connected to the bottom of the side blocks. Sliding components are provided at the bottom of the sliding rods. An adjustment component is provided at the top of the positioning plate. A traction component is provided at the bottom of the two front side blocks.

[0008] Through the above technical solution: the components of the guiding mechanism work together, the bracket provides stable support, the clamping plate, together with the side block, slide bar and sliding assembly, makes the vertical movement of the gun barrel stable and smooth, the distance adjustment assembly and the traction assembly can adjust the clamping plate spacing to adapt to different specifications of gun barrels, thus enhancing the versatility and practicality of the gun head structure.

[0009] As a further description of the above technical solution: The acceleration component includes a conical converging section, the outer wall of which is fixedly connected to the inner wall of the nozzle, and the top of the conical converging section has multiple spiral channels.

[0010] Through the above technical solution: the acceleration component uses a conical contraction section to accelerate the water flow, and the spiral channel gives the water flow spiral motion characteristics, which enhances the impact force and dispersion effect of the water flow, thereby improving the punching efficiency.

[0011] As a further description of the above technical solution: The sliding assembly includes multiple pulleys, the tops of which are rotatably connected to the bottoms of multiple sliding rods, and the top of the positioning plate has two sliding grooves.

[0012] The above technical solution involves the pulley and the groove working together to convert sliding friction into rolling friction, reducing motion resistance and ensuring smoother movement of the barrel when the clamp moves, thus improving the stability of vertical positioning.

[0013] As a further description of the above technical solution: The adjusting assembly includes a fixing plate, the bottom of which is fixedly connected to the top of the positioning plate, and a screw is threadedly connected to the inner wall of the fixing plate.

[0014] The above technical solution provides a power transmission basis for adjusting the spacing between the clamping plates through the threaded connection between the screw and the fixed plate. The position of the clamping plates can be adjusted by rotating the screw to meet different needs.

[0015] As a further description of the above technical solution: The traction assembly includes a rotating shaft, the inner wall of which is rotatably connected to the rear end of the screw, and the outer wall of which is rotatably connected to two rotating plates.

[0016] Through the above technical solution, the traction component converts the rotational motion of the screw into the oscillation of the rotating plate, which in turn drives the movement of the slide bar and the clamping plate, thereby achieving flexible adjustment of the clamping plate spacing.

[0017] As a further description of the above technical solution: The top of the gun barrel is connected to a U-shaped punch pipe, and the left side of the U-shaped punch pipe is connected to a high-pressure water pump.

[0018] The above technical solution connects the high-pressure water pump and the gun barrel, ensuring that the high-pressure water flow generated by the high-pressure water pump can be stably delivered to the gun barrel, providing sufficient power for the punching operation.

[0019] As a further description of the above technical solution: The gun barrel is fixedly connected to the gun body on its outer wall, and the inner walls of the two rotating plates are rotatably connected to the outer walls of the two front sliding rods, respectively.

[0020] Through the above technical solutions: the gun body makes it easy for operators to hold and control the gun head structure, making the operation process easier to control; the rotational connection between the rotating plate and the slide bar ensures the smooth realization of the function of adjusting the clamping plate spacing of the traction component.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the expansion wing in the anti-blocking mechanism supports the nozzle and prevents the nozzle from contacting the soil, thereby avoiding nozzle blockage. The structure of the guide channel and protective cover guides the splash and blocks mud splash. At the same time, the design of the conical contraction section and spiral channel in the acceleration component increases the water flow speed and generates spiral motion, which acts on the soil with a stronger impact force, thereby improving the drilling efficiency.

[0022] 2. In this utility model, through the threaded connection between the fixed plate and the screw in the adjusting assembly, and the rotational connection between the rotating shaft, the rotating plate and the slide rod in the traction assembly, the rotating screw can drive the clamping plate to move, thereby realizing the flexible adjustment of the clamping plate spacing. This allows the guiding mechanism to be adapted to various types of gun barrels, enhancing the versatility and practicality of the punching water gun head structure, and thus improving the stability and efficiency of the entire punching operation process.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] See attached document Figure 2 and attached Figure 3 The present invention provides an embodiment of a punching water gun head structure, including a gun barrel 1, which serves as a water flow channel. An anti-blocking mechanism 2 is provided at the bottom of the gun barrel 1 to prevent mud from splashing. A positioning plate 3 is slidably connected to the outer wall of the gun barrel 1 to provide an installation base for a guide mechanism 4. A guide mechanism 4 is provided at the top of the positioning plate 3 to vertically position the gun barrel 1. The anti-clogging mechanism 2 includes a nozzle 201. The top of the nozzle 201 is connected to the bottom of the barrel 1 and is the terminal component for the high-pressure water jet, providing impact power for the punching operation. Multiple expansion vanes 202 are fixedly connected to the outer wall of the nozzle 201 to support the nozzle 201 and keep it at a distance from the soil to prevent clogging. At the same time, they guide the splashed water and mud. Multiple guide grooves 203 are opened on the outer wall of the multiple expansion vanes 202 to change the trajectory of the splash generated during punching, reduce the risk of mud splashing everywhere and nozzle 201 clogging. The top of the multiple expansion vanes 202 is fixedly connected to the same protective cover 204 to further block mud from splashing towards the nozzle 201, enhance the anti-clogging effect, and prevent damage to the operator's eyes and skin. An acceleration component 205 is set inside the nozzle 201 to accelerate the water flow, increase the water flow impact force, improve punching efficiency, and reduce mud residue. Specifically, during the punching operation, the anti-clogging mechanism 2, through the coordinated work of its components, prevents soil blockage and improves punching efficiency. High-pressure water flows downwards into the nozzle 201 within the barrel 1. The top of the nozzle 201 connects to the bottom of the barrel 1, providing an outlet channel for the water flow. Multiple expansion vanes 202, fixedly connected to the outer wall of the nozzle 201, lift the nozzle 201, maintaining a certain distance from the soil to prevent direct contact between the nozzle 201 and the soil during punching, thus physically isolating the risk of blockage. Simultaneously, multiple guide grooves 203 on the outer wall of the expansion vanes 202 directionally guide the splashed water and mud generated during punching. When the water flow impacts the soil and generates splashes, the guide channel 203 changes its trajectory, allowing it to flow along the channel, reducing mud splashing everywhere, and thus reducing the probability of mud adhering to the nozzle 201 and causing blockage. The tops of multiple expanding vanes 202 are fixedly connected to the same protective cover 204, forming a protective barrier to further prevent mud from splashing towards the nozzle 201, providing all-round protection for the nozzle 201. The acceleration component 205 inside the nozzle 201 is specially designed to accelerate the water flow, allowing the water flow to be ejected at a higher speed and with a stronger impact force, quickly impacting the soil to complete the perforation, reducing soil residue, and indirectly reducing the probability of blockage.

[0027] See attached document Figure 1 Appendix Figure 2 and attached Figure 5The guiding mechanism 4 includes a bracket 401, the top of which is fixedly connected to the bottom of the positioning plate 3 to provide a stable mounting support base for the guiding mechanism 4. Two clamping plates 402 are slidably connected to the outer wall of the barrel 1 to tightly fit the barrel 1, restricting its movement and making its vertical movement more stable. Two side blocks 403 are fixedly connected to the outer walls of each clamping plate 402 to connect to sliding rods 404 and transmit motion and force. Sliding rods 404 are fixedly connected to the bottom of each of the side blocks 403 to support the sliding assembly 405 and guide its movement in a specific direction. Sliding assemblies 405 are provided at the bottom of each of the sliding rods 404. Each sliding assembly 405 includes multiple pulleys 4051, the tops of which are rotatably connected to the bottoms of the sliding rods 404, converting sliding friction into rolling friction, reducing motion resistance, and ensuring smooth movement of the clamping plate 402. Two grooves 4052 are formed on the top of the positioning plate 3 to cooperate with the pulleys 4051 and limit their movement trajectory. The top of the positioning plate 3 is provided with a distance adjustment component 406 for adjusting the distance between the clamping plates 402. The distance adjustment component 406 includes a fixing plate 4061, the bottom of which is fixedly connected to the top of the positioning plate 3 to provide a mounting base for the screw 4062. The screw 4062 is threadedly connected to the inner wall of the fixing plate 4061. The distance is adjusted by rotating the screw 4062. The bottom of the two front side blocks 403 is provided with a traction component 407 to convert the rotational motion of the screw 4062 into... The linear movement of the clamping plate 402 is achieved by the traction assembly 407, which includes a rotating shaft 4071. The inner wall of the rotating shaft 4071 is rotatably connected to the rear end of the screw 4062, thereby achieving a rotatable connection between the screw 4062 and the rotating plate 4072. The outer wall of the rotating shaft 4071 is rotatably connected to two rotating plates 4072, which are used to convert the rotation of the screw 4062 into the movement of the slide bar 404. The inner walls of the two rotating plates 4072 are rotatably connected to the outer walls of the two front slide bars 404, respectively, to ensure that the rotating plates 4072 drive the slide bars 404 to move. Specifically, in the guide mechanism 4, the top of the bracket 401 is fixed to the bottom of the positioning plate 3 as a basic support structure. Two clamping plates 402 are slidably sleeved on the outer wall of the barrel 1. The side block 403 of its outer wall is fixedly connected to the slide rod 404. The pulley 4051 at the bottom of the slide rod 404 cooperates with the top slide groove 4052 of the positioning plate 3 to realize the vertical sliding guide of the barrel 1. In the distance adjustment assembly 406, the fixing plate 4061 is fixed to the top of the positioning plate 3. The screw 4062 is threadedly connected to the fixing plate 4061. The rotating shaft 4071 of the traction assembly 407 is sleeved on the rear end of the screw 4062. The rotating plate 4072 is rotatably connected to the rotating shaft 4071 and the front slide rod 404 respectively. By rotating the screw 4062, the rotating plate 4072 is driven to swing, realizing the adjustment of the distance between the clamping plates 402 to adapt to different specifications of barrels 1.

[0028] See attached document Figure 1 Appendix Figure 2and attached Figure 4 The acceleration component 205 includes a conical converging section 2051. The outer wall of the conical converging section 2051 is fixedly connected to the inner wall of the nozzle 201. It is used to accelerate the water flow through the gradually converging channel structure. The top of the conical converging section 2051 is provided with multiple spiral channels 2052 to give the water flow spiral motion characteristics and enhance the impact force and dispersion effect of the water flow. The top of the gun barrel 1 is connected to a U-shaped punch pipe 5, which is used to connect the high-pressure water pump 6 to the gun barrel 1 to stably deliver high-pressure water flow. The left side of the U-shaped punch pipe 5 is connected to the high-pressure water pump 6 to provide high-pressure water flow power for the entire system. The outer wall of the gun barrel 1 is fixedly connected to the gun body 7 to facilitate the operator to hold and operate the gun head structure. Specifically, the tapered converging section 2051 of the acceleration component 205 accelerates the water flow through the converging channel, while the spiral channel 2052 imparts a spiral motion to the water flow. The combination of these two elements enhances the impact force and dispersion effect of the water flow, thereby improving punching efficiency. The U-shaped punching pipe 5 connects the high-pressure water pump 6 and the gun barrel 1, ensuring a stable transmission of high-pressure water flow and guaranteeing power supply. The gun body 7 is easy for operators to hold and control, making the entire gun head easier to control during operation. All components work together to ensure that the punching operation is efficient, precise, and stable.

[0029] Working Principle: After the equipment is fixed in the corresponding position, the high-pressure water pump 6 starts, pressurizing the water flow and delivering it through the pipeline to the U-shaped flushing pipe 5. The U-shaped flushing pipe 5 acts as a bridge connecting the high-pressure water pump 6 and the gun barrel 1, guiding the high-pressure water flow into the gun barrel 1. The water flow flows downward along the internal channel of the gun barrel 1, providing power for subsequent punching operations. When the water flow reaches the bottom of the gun barrel 1, it enters the nozzle 201 in the anti-clogging mechanism 2. The conical contraction section 2051 in the acceleration component 205 inside the nozzle 201 causes the channel to gradually narrow as the water flow passes through. According to the principles of fluid mechanics, the water flow velocity will increase as the channel narrows. At the same time, the multiple spiral channels 2052 opened at the top of the conical contraction section 2051 give the water flow the characteristics of spiral motion. After the spiral motion water flow exits the nozzle 201, it not only has a higher speed, but also acts on the soil with a more dispersed and powerful impact force, improving punching efficiency. During the process of water flow impacting the soil for drilling, the anti-clogging mechanism 2 ensures the normal operation of the nozzle. The multiple expansion vanes 202 on the outer wall of the nozzle 201 first play a supporting role, lifting the nozzle 201 and keeping it at a certain distance from the soil to prevent the nozzle 201 from being blocked due to direct contact with the soil. At the same time, the multiple guide grooves 203 opened on the outer wall of the expansion vanes 202 guide the splashed water and mud generated during the drilling process, change their splash direction, and make the mud and water flow along the guide grooves 203, reducing splashing to all sides and reducing the risk of mud adhering to the nozzle 201 and causing blockage. In addition, the same protective cover 204 fixedly connected to the top of the multiple expansion vanes 202 further blocks mud splashing, protects the nozzle 201 in all directions, and ensures that it continuously and stably sprays high-pressure water flow. When the barrel 1 moves up and down to perform drilling operations, the positioning plate 3 and the guide mechanism 4 work together to ensure the accurate positioning of the barrel 1. Furthermore, during the operation of the perforating water gun, the guide mechanism 4 achieves precise vertical positioning and flexible adjustment of the barrel 1 through the coordinated operation of its various components. The bracket 401 provides installation support for the entire guide mechanism 4. The side block 403, slide rod 404, and sliding assembly 405 on the positioning plate 3 constitute the guide rail for the movement of the two clamping plates 402. The pulley 4051 is rotatably connected to the bottom of the slide rod 404 and cooperates with the groove 4052 opened on the top of the positioning plate 3. When the clamping plate 402 moves, the pulley 4051 rolls in the groove 4052, converting sliding friction into rolling friction and reducing motion resistance. The adjusting assembly 406 and the traction assembly 407 give the guide mechanism 4 the ability to adjust and adapt. The fixing plate 4061 is fixed to the top of the positioning plate 3, and the screw 4062 is connected to the fixing plate. The 4061 threaded connection allows the traction component 407 to move by rotating the screw 4062. The rotating shaft 4071 is sleeved on the rear end of the screw 4062 and can rotate. The two rotating plates 4072 are rotatably connected to the rotating shaft 4071 and the front slide rod 404. When the screw 4062 is rotated, the rotational motion of the screw 4062 is converted into the linear movement of the rotating shaft 4071. The rotating plates 4072 rotate accordingly, thereby driving the front slide rod 404 and the clamping plate 402 connected to it to move, realizing the adjustment of the distance between the clamping plates 402. This allows the guide mechanism 4 to flexibly adjust the distance between the clamping plates 402 according to different specifications of the gun barrel 1, ensuring that it can adapt to various models of gun barrel 1. This enhances the versatility and practicality of the punching water gun head structure, making the entire punching operation process more stable and efficient.
