Detailed implementation manners

[0013] The technical solutions of the present application will be further described in detail below in conjunction with the specific implementation manners.

[0014] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0015] Please refer to Figures 1 to 12 , in one embodiment, a nozzle connection device for a flexible water pipe includes a branch pipeline 2, a joint pipe 8, a nozzle 6, and a main pipeline 1. A plurality of branch pipelines 2 are fixedly installed on the main pipeline 1, and a joint pipe 8 is movably installed on the branch pipeline 2. The device further includes a corrugated pipe 3 and an external thread plate 26. One end of the joint pipe 8 is connected to a corrugated pipe 3, the end of the corrugated pipe 3 away from the joint pipe 8 is connected to a connecting pipe 4, a plurality of shunt pipes 5 are connected to the connecting pipe 4, valves are provided on the shunt pipes 5, and nozzles 6 are provided on the outer end faces of the shunt pipes 5; An external thread plate 26 is provided on the joint pipe 8, a plurality of arc-shaped plates 10 are installed in the branch pipeline 2, a third spring 25 is connected between the arc-shaped plates 10 and the branch pipeline 2, internal thread grooves 100 are formed in the inner walls of the plurality of arc-shaped plates 10, the internal thread grooves 100 are matched with the external thread plate 26, a flange 27 is provided at one end of the joint pipe 8, a diversion cover 28 is fixedly installed at one end of the branch pipeline 2, there is a gap between the diversion cover 28 and the arc-shaped plates 10, a bearing cover 29 is fixedly connected to the end of the arc-shaped plates 10 away from the diversion cover 28, and the flange 27 is of a spindle-shaped annular structure.

[0016] In this embodiment, two shunt pipes 5 are connected to the connecting pipe 4, and the inner diameter of the branch pipeline 2 is larger than the inner diameter of the joint pipe 8.

[0017] During installation, first hold the joint structure, that is, the joint pipe 8 and the flange 27. The inner surface of the load-bearing cover 29 is an inclined surface. The joint structure is held and squeezed. Under the action of the squeezing force, the arc plate 10 is forced to open. At this time, the joint structure can move vertically at the center of the arc plate 10. When the flange 27 moves to the top of the arc plate 10, the arc plate 10 tends to close inward. Then rotate the joint structure. When the spatial positions of the external thread plate 26 and the internal thread groove 100 correspond one to one, the arc plate 10 is under the action of the third spring 25. By closing it down, that is, the external threaded plate 26 extends into the internal threaded groove 100, the vertical locking of the joint structure and the branch pipe 2 is completed. At the same time, the deflector 28 is tightly attached to the end of the joint pipe 8, so that the branch pipe 2 and the joint structure can be quickly clamped. In the prior art, the connection between the nozzle 6 and the main pipe 1 generally adopts a threaded connection, and the threaded connection requires the nozzle 6 to be in a horizontal position during installation, and it needs to maintain horizontal rotation during manual rotation. The installation of the nozzle 6 is a high-altitude operation, which is inconvenient to operate. It is difficult to ensure its horizontal rotation during installation, and it is easy to misalign.

[0018] When the joint structure needs to be disassembled due to a malfunction or other reasons, since the flange 27 is set as a spindle ring structure, that is, the upper end and the lower end of the flange 27 are both inclined structures, when the load-bearing cover 29 is extruded, the extrusion and expansion effect is better by fitting with the load-bearing cover 29.

[0019] When disassembling, since the external thread plate 26 is engaged with the internal thread groove 100, the joint pipe 8 cannot move vertically. Therefore, the other end of the joint pipe 8 is manually rotated in the opposite direction to make the joint pipe 8 drop until the flange 27 opens the arc plate 10 again. At this time, it can be pulled out with force. Disassembly is achieved by rotation, which can prevent the nozzle head 6 from being detached due to vibration or collision.

[0020] See also Figure 5 , Figure 6 In one embodiment, a guide plug 7 is provided in the connecting pipe 4.

[0021] In this embodiment, by providing a guide plug 7, the inner diameter of the diverter pipe 5 is smaller than the inner diameter of the connecting pipe 4, so that the water in the connecting pipe 4 can be guided to the diverter pipes 5 on both sides, and the flow rate can be further increased during the guiding process.

[0022] See also Figure 10 In one embodiment, a cover plate 9 is rotatably mounted on one end of the branch pipe 2 located in the main pipe 1 , and a push rod 30 is clamped on one end of the joint pipe 8 located in the branch pipe 2 .

[0023] In this embodiment, an annular groove 81 is formed on the inner wall of the adapter pipe 8, and a plurality of fixing blocks 82 are fixedly installed in the annular groove 81. The ejector rod 30 has an L-shaped structure. When performing clamping, one end of the ejector rod 30 is located in the gap between adjacent fixing blocks 82, so as to realize the clamping of the ejector rod 30. The rotation plane of the cover plate 9 coincides with the water flow direction, and the rotation point of the cover plate 9 is closer to the water flow starting point.

[0024] During installation, when the flange 27 moves to the top of the arc-shaped plate 10, at this time, the ejector rod 30 can lift the cover plate 9, and the water in the main pipeline 1 flows into the adapter pipe 8 from the opened position.

[0025] During disassembly, the ejector rod 30 is separated from the cover plate 9, and the cover plate 9 rotates under the action of the water flow, so that one end of the branch pipeline 2 fits with the cover plate 9 to achieve closing. A sealing gasket is provided on the branch pipeline 2.

[0026] Please refer to Figure 10 , in one embodiment, the ejector rod 30 is eccentrically arranged.

[0027] In this embodiment, the opening degree of the cover plate 9 can be further adjusted by the eccentrically arranged ejector rod 30, so that the flow rate and the flow volume can be adjusted.

[0028] During installation, first adjust the position of the ejector rod 30. The position is relative to the end point of the threaded plate at one end of the adapter pipe 8. Different positions of the ejector rod 30 correspond to different opening degrees of the cover plate 9. Then hold the joint structure, that is, the adapter pipe 8 and the flange 27. The inner surface of the bearing cover 29 is inclined. Hold the joint structure and squeeze the bearing cover 29. Under the action of the squeezing force, the arc-shaped plate 10 is forced to open. At this time, the joint structure can move vertically at the center position of the arc-shaped plate 10. During the vertical movement, the ejector rod 30 moves synchronously. When the flange 27 moves to the top of the arc-shaped plate 10, at this time, the arc-shaped plate 10 has a tendency to close inward. The ejector rod 30 lifts the cover plate 9 at this time. Then rotate the joint structure. When the outer threaded plate 26 and the inner threaded groove 100 are in one-to-one correspondence in terms of spatial position, the arc-shaped plate 10 closes under the action of the third spring 25, that is, the outer threaded plate 26 extends into the inner threaded groove 100. At this time, the position of the adapter pipe 8 is fixed, and the vertical locking of the joint structure and the branch pipeline 2 is completed. At the same time, the flow guide cover 28 is tightly attached to the end of the adapter pipe 8.

[0029] When disassembling, since the external thread plate 26 is engaged with the internal thread groove 100, the joint pipe 8 cannot move vertically. Therefore, the other end of the joint pipe 8 is manually rotated in the opposite direction to make the joint pipe 8 drop until the flange 27 opens the arc plate 10 again. At this time, the top rod 30 is disengaged from the cover plate 9, and the cover plate 9 rotates under the action of the water flow, so that one end of the branch pipe 2 is fitted with the cover plate 9 to achieve closure, and then the joint structure can be pulled out with force.

[0030] During the disassembly process, the main pipe 1 and the branch pipe 2 can maintain a closed and sealed state. In the prior art, only threaded connection is used, and the disassembly of the nozzle 6 requires water shut-off operation. In the present invention, the disassembly of the joint structure can be performed without shutting off the water.

[0031] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, it also includes a frame 14, one end of which is installed on the top beam, and sliding frames 16 are slidably installed on both sides of the other end of the frame 14, a first spring 20 is connected between the sliding frame 16 and the frame 14, and a clamping plate 24 is installed on the sliding frame 16, and the clamping plate 24 is used to clamp the connecting pipe 4.

[0032] In this embodiment, a gear 13 is fixedly mounted on the frame 14, a rack 12 is slidably mounted on the top beam, a first telescopic member 11 is mounted on the wall, an output end of the first telescopic member 11 is connected to the rack 12, a plurality of frames 14 are arranged in the flow direction of water in the main pipe 1, and a plurality of gears 13 are arranged at the same time, the rack 12 is meshed and connected with the plurality of gears 13, and the telescopic movement of the first telescopic member 11 drives the plurality of frames 14 to rotate at a small angle, and the rotation angle is less than 90 degrees.

[0033] By providing a rack 12 and a gear 13, the angle of the frame 14 can be fine-tuned. During the actual installation of the frame 14, it is installed along the branch pipe 2 in the main pipe 1. It is generally installed in a matrix, that is, the telescopic movement of a rack 12 can drive the rotation of several frames 14. The rotation angle of the frame 14 can be generated by judging the position where water needs to be discharged, so that the nozzle 6 is facing the position where water needs to be discharged.

[0034] See also Figure 1 , Figure 2 , Figure 3 In one embodiment, a rotating tube 22 is rotatably mounted on the sliding frame 16, a connecting rod 23 is slidably mounted on one end of the rotating tube 22, a second spring 21 is connected between the rotating tube 22 and the connecting rod 23, and a clamp 24 is fixedly mounted on one end of the connecting rod 23 away from the rotating tube 22.

[0035] In this embodiment, a pressure bar 17 is placed on the rotating pipe 22 connected to several of the frames 14. The pressure bar 17 is located below several frames 14, and second telescopic members 15 are installed at both ends of the pressure bar 17.

[0036] By providing a clamping plate 24, the positions of the communicating pipe 4 and the nozzle 6 can be clamped and fixed, which can avoid being affected by external forces. Secondly, under the action of the second telescopic member 15, the pressure bar 17 can be driven to move. While the pressure bar 17 moves, the communicating pipes 4 in the same row are driven to descend. The parameters of the corrugated pipe 3 determine the ultimate descending height of the communicating pipe 4. While the communicating pipe 4 descends, the water path of the corrugated pipe 3 can be extended, so that the water in the communicating pipe 4 can obtain a greater flow rate. The greater flow rate is obtained based on the reduction of the gravitational potential energy of the water.

[0037] Please refer to Figure 1 、 Figure 2 、 Figure 3 , in one embodiment, the other end of the rotating pipe 22 is connected to a driving member 19.

[0038] In this embodiment, by providing a driving member 19, the communicating pipe 4, the shunt pipe 5 and the nozzle 6 can be rotated at a certain angle.
