Detailed implementation mode

[0025] The present utility model will be further described through implementation modes. As shown in the attached drawings, the following description is only an exemplary explanation. Those skilled in the art can make further structural improvements based on the following explanation. The protection scope of the horizontal swing type sprinkler system shall be subject to the scope recorded in the claims.

[0026] Embodiment 1:

[0027] A horizontal swing type sprinkler system, as shown in the attached drawings, includes a water delivery pipe 1. The water delivery pipe 1 is in a right-angle elbow structure. A bottom elbow 11 is arranged at the bottom of the water delivery pipe 1 and is connected to a swing connection assembly 3 through the bottom elbow 11. The swing connection assembly 3 includes an inner plate 32 and an outer plate 31. Horizontal joints 37 are arranged on the inner plate 32 and the outer plate 31, and a horizontal hose 39 is arranged between the two horizontal joints 37. The four corners of the inner plate 32 and the outer plate 31 are hinged through connecting rods 30. Further, to achieve the angular swing between the two, bending plates 34 are arranged at the top and bottom of the inner plate 32 and the outer plate 31, and long holes 35 are arranged on the bending plates for connecting with the connecting rods 30. Through such long holes 35, the avoidance during the swing of the connecting rods 30 can be realized. Through the above structural settings, one side of the outer plate 31 is connected to the water supply end of the vehicle, the inner plate 32 is connected to the sprinkler end, and the four corners of the inner plate 31 and the outer plate 32 are hinged through connecting rods 30, so that a quadrangular prism connection structure can be formed at the joint of the water supply end and the sprinkler end, and the skew angle compensation during the connection of the two can be realized within a certain range, avoiding loosening or breaking at the joint.

[0028] A fixed disk 12 is provided at the top of the water delivery pipe 1 and is fixed to an external connecting beam 74 through the fixed disk 12; a rotary disk assembly 2 is fixed on the fixed disk 12, a pipe head connecting portion 13 is provided at the center of the axis of the fixed disk 12, the pipe head connecting portion 13 is of a tubular structure and protrudes from the top surface structure of the fixed disk 12, and the pipe head connecting portion 13 is communicated with the water delivery pipe 1; a pre-embedded groove is provided inside the pipe head connecting portion 13, a water seal member 8 is fixed through the pre-embedded groove, a connecting pipe 4 is inserted inside the pipe head connecting portion 13, and the water seal member 8 is arranged between the connecting pipe 4 and the pipe head connecting portion 13. The water seal member 8 is arranged in a stacked spiral structure with multiple upper and lower layers, and multiple-layer sealing is realized through the water seal members arranged in a stacked spiral manner at multiple axial intervals. The above structure can ensure the seal between the connecting pipe 4 and the pipe head connecting portion 13. However, when high-pressure liquid is introduced, without restraint, the high-pressure liquid will impact the connecting pipe 4 out of the pipe head connecting portion 13. To prevent the above problems, the present utility model is provided with an extension plate 41 on the connecting pipe 4, a fixing hole is provided on the extension plate 41, and the extension plate 41 is connected to the upper rotating portion 22 of the rotary disk assembly 2 through the fixing hole. The lower rotating portion 21 of the rotary disk assembly 2 is connected to the fixed disk 12; further, there are two extension plates 41 and they are evenly arranged around the connecting pipe 4. In this embodiment, the extension plate 41 is welded and fixed on the outer wall of the connecting pipe 4 and the two form an integral body. A long strip fixing hole 42 is provided on the extension plate 41, and axial displacement adjustment can be realized.

[0029] When the present utility model is assembled, the bolt for fixing between the extension plate 41 and the upper rotating portion 22 is in a non-locked state, and a gap within 3 millimeters is left between the bottom surface of the bolt and the extension plate 41; after the high-pressure water source is introduced, the connecting pipe 4 can have a floating adjustment range of about 3 millimeters axially after being impacted by the high pressure, which can effectively avoid stress concentration at the fixed part of the connecting pipe itself and thus cause cracks or liquid leakage.

[0030] The top of the connecting pipe 4 is connected to a vertical hose through a hoop. The top of the vertical hose 5 is connected to an external water spraying pipe. The external water spraying pipe includes a transverse pipe 61 and a vertical main pipe 6. Both ends of the transverse pipe 61 are connected to a rotating frame 7, and the rotating frame 7 is locked and fixed to the upper rotating portion 22 of the rotary disk through bolts.

[0031] The hose is a vertical hose 5. The upper end of the vertical hose 5 is connected to the vertical main pipe 6 through two hoops, and the lower end of the vertical hose 5 is connected to the connecting pipe 4 through a single hoop. The connecting pipe is connected to the vertical main pipe 6 through the vertical hose 5, which can effectively realize the flexible connection of the upper part of the connecting pipe 4, avoid the high-pressure water impact at the water source outlet end, and avoid stress concentration at the external connection end of the connecting pipe 4. This structure realizes the energy buffering under regular or irregular impacts through the vertical hose 5 when the high-pressure liquid is unstable, and avoids problems such as liquid leakage.

[0032] The utility model designs the rotating frame 7 into a U-shaped structure, with its left and right sides extending vertically, and vertical plates 71 are respectively arranged at the top. The horizontal pipe 61 is supported and fixed through the vertical plates 71 on the left and right sides. This structure forms a main body by connecting the rotating frame 7 with the horizontal pipe 61 and the vertical main pipe 6, thereby improving the overall strength. Further, when the utility model is connected to an external spray frame, a hinge cylinder 73 and a locking plate 74 are arranged on the side of the vertical plate 71. The hinge cylinder 73 is used to hang the external spray frame, and the locking plate 74 is used for locking and fixing the external spray frame after it is extended. When the external spray frame is folded, the hinge cylinder 73 is used as a hinge shaft.

[0033] During the high-pressure operation process, to ensure the overall strength above the rotating frame 7, the utility model arranges two horizontal reinforcing pipes 62 between the two vertical plates 71 arranged on the left and right to be connected with the vertical main pipe 6, and two longitudinal reinforcing pipes 63 are also arranged on the two horizontal reinforcing pipes 62 to be connected with the vertical main pipe 6. The vertical main pipe 6 is covered by the intersection of the two horizontal reinforcing pipes 62 and the two longitudinal reinforcing pipes 63, so that the vertical main pipe 6 and the two vertical plates 71 form an integral body, and the overall strength inside the entire rotating frame 7 can be ensured even under high-pressure impact.

[0034] Further, as Figure 3 shown, the utility model welds two positioning plates 38 on the top of the outer plate 31 towards the inner plate. The positioning plates 38 are arranged close to the connecting rod 30. When the connecting rod 30 swings at a certain angle, the limit position between the connecting rod 30 and the positioning plates 38 can be fixed by inserting a vertical pin, preventing the two from swinging disorderly, so as to ensure the stability of the relative displacement between the outer plate 31 and the inner plate 32, and avoid the loosening and breaking of the horizontal hose 39.

[0035] In summary, the overall structure of this horizontal swing type spray system is simple and convenient to assemble. It can prevent the stress concentration at the connection point caused by the non-linear connection between the spray end and the traction end when the vehicle's water supply end and spray end turn during driving, and avoid damage to the connection pipeline; it increases the overall rigidity when connecting with an external extension frame body, and avoids the shaking and even damage of the rotating frame. It is an ideal horizontal swing type spray system.
