Description

Technical Field

[0001] The invention relates to the technical field of injection pipes, and in particular to a water flow injection pipe and an injection system. Background Art

[0002] High-pressure jet cleaning is to pressurize water through a pump source, and then pass it through a water jet pipe to form a high-pressure water jet. The current mainstream sweepers on the market use high-pressure jets to flush adhesive substances (adhesive sludge, soil slab lumps and oil stains, etc.). The outlet water pressure of the water jet pipe of the existing sweeper is controlled by the pump source. By adjusting the angle between the water jet pipe and the ground, the spray angle of the high-pressure jet can be adjusted. If the high-pressure jet rushes in from the junction of the ground and the adhesive substance, the adhesive substance can be quickly separated to achieve the purpose of cleaning the ground. However, adjusting the angle between the water jet pipe and the ground will also change the landing position of the water flow. The farther the landing position of the water flow is from the outlet of the water jet pipe, the lower the water pressure of the ground when it falls to the ground, which ultimately makes it difficult to remove the adhesive substances adhering to the ground when the water flow falls to the ground.

DETAILED DESCRIPTION

[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0029] Please refer to Figure 1-5 As shown, a water jet pipe of the present invention includes a device body; the device body includes a water jet pipe 1 made of metal material, a regulating ball valve for adjusting the water pressure of the water jet pipe 1 and a water sealer 3 arranged between the regulating ball valve and the water jet pipe 1; the water jet pipe 1 includes a water outlet pipe 11 and a water receiving pipe 12 threadedly connected to the water outlet pipe 11; the regulating ball valve is arranged between the water outlet pipe 11 and the water receiving pipe 12; the regulating ball valve includes a sphere 21 arranged in the water jet pipe 1 and a protruding protrusion 22 fixedly connected to the sphere 21; the protruding protrusion 22 has an adjusting portion extending out of the water jet pipe 1; the sphere 21 is rotatably connected to the water receiving pipe 12; the water sealer 3 includes a sliding rubber hose 31 arranged in the water receiving pipe 12 and a resisting spring 32 that resists the sliding rubber hose 31 to squeeze the sphere 21; the sliding rubber hose 31 includes a rubber tube wall that fits the inner hole wall of the water receiving pipe 12. In the actual implementation process, the water jet pipe is constantly fed with water, and after the protrusion 22 is fixedly extended, the water outlet pipe 11 is driven to rise and fall and swing, prompting the regulating ball valve to rotate; Figure 2 When set as shown; the outlet pipe 11 swings downward, the water surface connected to the inner hole of the outlet pipe 11 by the regulating ball valve changes from small to large, and the water flow channel entering the outlet pipe 11 through the regulating ball valve changes from small to large, thereby reducing the outlet water pressure; conversely, the outlet water pressure gradually increases; when flushing the ground, the size of the water flow channel is adjusted by adjusting the ball valve, so that the flushing water pressure at the far landing point is close to the flushing water pressure at the near landing point, and maintained within a controllable range, so that the water flow can effectively flush the ground when it hits the ground, and separate the adhesive substances adhering to the ground.

[0030] Among them, the water spray pipe 1 is made of metal material, which can effectively prevent hard objects on the ground from hitting the water spray pipe 1 and causing damage to the water spray pipe 1, thereby increasing the service life of the water spray pipe 1; one function of the water sealer 3 is to seal the connection between the regulating ball valve and the water receiving pipe 12 to prevent water leakage; the second function is to squeeze the ball 21, increase the friction force when the ball 21 rotates, effectively prevent the ball 21 from rotating unintentionally, and make the water pressure regulation more precise.

[0031] Optionally, the water outlet pipe 11 includes a straight pipe section 111 and a tapered pipe section 112 connected to the straight pipe section 111; the water receiving pipe 12 includes a connecting pipe section 121 extending into the straight pipe section 111; the ball 21 is arranged between the connecting pipe section 121 and the tapered pipe section 112; and the rubber tube wall is sealed between the ball 21 and the connecting pipe section 121. In the actual implementation process, the ball 21 is limited by the tapered pipe section 112 and the connecting pipe section 121; at the same time, the rubber tube wall can be elastically deformed toward the ball 21, so as to better seal the connection position between the connecting pipe section 121 and the ball 21 and prevent water leakage.

[0032] Optionally, the straight pipe section 111 includes an avoidance groove for installing the protruding protrusion 22; the device body has a slide plate 113 matching the avoidance groove. In the actual implementation process, during installation, the protruding protrusion 22 enters the avoidance groove from the opening of the avoidance groove, and the slide plate 113 is installed to limit the protruding protrusion 22. After that, the water outlet pipe 11 is threadedly connected with the water receiving pipe 12, and the slide plate 113 is limited by the water receiving pipe 12. The purpose of this structural design is to facilitate assembly.

[0033] In actual use, the water outlet pipe 11 will inevitably be blocked. Since multiple water outlet pipes 11 are arranged at the bottom of the cleaning vehicle, the blockage is not easy to be found and unblocked. Especially in winter, water is easily retained in the conical pipe section 112 of the water outlet pipe 11. In addition, the cold weather causes the retained water to freeze into ice and block the conical pipe section 112. Optionally, the water outlet pipe 11 also includes a dredging mechanism disposed on the conical pipe section 112; the dredging mechanism includes a dredging rod 41, a support seat 42 fixedly connected to the conical pipe section 112, and a return spring 43 supported between the dredging rod 41 and the support seat 42; the conical pipe section 112 includes an outer pipe wall and a conical hole disposed in the outer pipe wall; the dredging rod 41 is obliquely inserted into the conical hole from the outer pipe wall; and the dredging rod 41 moves along the axial direction of the conical hole. In the actual implementation process, when the water outlet pipe 11 is blocked, the water outlet pipe 11 can be unblocked by the unblocking mechanism; specifically, by squeezing the unblocking rod 41 to move the unblocking rod 41, the reset spring 43 is compressed, and the blockage is pushed out along the axial direction of the tapered hole, thereby quickly unblocking the water outlet pipe 11; after the squeezing force is removed, the reset spring 43 is reset, which can push the unblocking rod 41 to reset.

[0034] Optionally, the dredging rod 41 includes an extended end portion 411 that can extend out of the tapered hole; the water outlet pipe 11 also includes a baffle plate 114 disposed on the extended end portion 411; the baffle plate 114 is connected to the extended end portion 411 through a torsion spring. In the actual implementation process, one-time dredging through the baffle plate 114 can effectively increase the amount of dredged ice output. At the same time, when water is sprayed, the water pressure will push the baffle plate 114 to swing, and the torsion spring will accumulate force to avoid obstructing the water spraying. When the water spraying stops, the torsion spring can drive the baffle plate 114 to reset. The baffle plate 114 can also prevent external debris from entering the interior of the conical pipe section 112, blocking the debris outside. In conjunction with the dredging rod 41, the conical pipe section 112 can be efficiently dredged.

[0035] Optionally, the device body also includes a water inlet pipe 5; the water inlet pipe 5 is connected between the water inlet pipe 6 and the water connecting pipe 12; the water inlet pipe 5 includes a clamping mechanism for movably clamping the water inlet pipe 6; the water inlet pipe 5 includes a mounting groove 51 for installing the clamping mechanism; the mounting groove 51 is arranged on the pipe wall of the water inlet pipe 5; the mounting groove 51 includes an annular wall 52 extending radially along the water inlet pipe 5; the clamping mechanism includes a cap 53 threadedly connected to the annular wall 52, a sliding plug rod 54 slidably connected to the cap 53, and a pre-tightening spring 55 that pushes the sliding plug rod 54 to move toward the inner side of the water inlet pipe 5; wherein, the water inlet pipe 6 has an annular groove 61 on its outer peripheral surface; the sliding plug rod 54 has an insertion section that passes through the pipe wall of the water inlet pipe 5 and is inserted into the annular groove 61. In the actual implementation process, the water inlet pipe 5 is connected to the water connecting pipe 12 through a thread. The purpose of setting the water inlet pipe 5 is to quickly disassemble and assemble the water inlet pipe 6. Specifically, during installation, the sliding rod 54 can be pulled outward to compress the pre-tensioning spring 55, and then the water inlet pipe 6 is inserted into the water inlet pipe 5. The sliding rod 54 is released, and the sliding rod 54 is driven to reset and snap into the annular groove 61 under the recovery action of the pre-tensioning spring 55.

[0036] Optionally, the water inlet pipe 6 has an inner extension section extending into the water inlet pipe 5; the device body also includes a sliding pipe sleeve 71 arranged in the water inlet pipe 5 and a sealing ring 72 connected between the sliding pipe sleeve 71 and the inner extension section; the push-up spring 32 pushes between the sliding pipe sleeve 71 and the sliding rubber tube 31. In the actual implementation process, the connection between the water inlet pipe 6 and the water inlet pipe 5 can be effectively sealed by setting the sealing ring 72, and at the same time, after the water inlet pipe 6 is fixed, the push-up spring 32 is compressed, which not only provides a push-up force for the sliding pipe sleeve 71, but also provides an extrusion force for the sliding rubber sleeve; the sliding pipe sleeve 71 and the sliding rubber sleeve are prompted to have a tendency to move to the two sides respectively, and the sliding pipe sleeve 71 can squeeze the sealing ring 72, so that the connection of the sealing ring 72 is more firmly secured.

In the actual implementation process, after the limit support 81 is fixedly extended out of the protrusion 22, the eccentric wheel 83 cooperates with the swing rod 82 to effectively drive the water outlet pipe 11 to swing up and down; during the upward swinging process, the push rod 84 gradually pushes the dredging plug rod 41 to extend to dredge the water outlet pipe 11.

[0038] Optionally, the spray system includes a spray row; the spray row includes a plurality of spray units and a driving mechanism for driving the plurality of spray units to move synchronously; the driving mechanism includes a driving rod 85; and the eccentric wheels 83 of the plurality of spray units are connected to the driving rod 85.
