Description

Technical Field

[0001] This utility model belongs to the field of water sprinkler technology for earth and rock dam construction, specifically relating to a strip sprinkler device. Background Technology

[0002] During the construction of earth-rock dams, the compaction quality of the fill material is one of the important factors determining the overall stability and safety of the dam body, and the optimal moisture content control of the fill material is a key link affecting the compaction quality. Practice shows that if the moisture content of the soil deviates from the optimal value, it can easily lead to uneven compaction, increased permeability, and local deformation, thereby affecting the overall seepage resistance and shear resistance of the dam body. Currently, water trucks equipped with single nozzles are commonly used for watering operations on construction sites. However, this method has the disadvantage of a diffuse circular spray range, with water flow concentrated in local areas, and the spray intensity is greatly affected by external factors such as nozzle angle and vehicle speed. This results in some areas having excessively high moisture content and others having excessively low moisture content, making it difficult to meet the requirements for large-area watering of earth-rock dams. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a strip sprinkler device to address the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a strip-type sprinkler device, characterized in that: it includes a water distribution pipe and an inlet pipe disposed on the rear side of the middle of the water distribution pipe and connected to the water tank supply pipe; an electromagnetic flow valve is installed on the pipe connecting the water tank supply pipe and the inlet pipe; the water distribution pipe is connected to the bottom of the sprinkler truck through multiple connecting components; multiple fan-shaped nozzles evenly distributed along the length of the water distribution pipe are provided at the bottom of the water distribution pipe; each fan-shaped nozzle has a nozzle opening, and the opening angle of the nozzle opening is... Where L is the spacing between two adjacent fan-shaped nozzles, and H is the height of the fan-shaped nozzle orifice from the ground.

[0005] The above-mentioned strip sprinkler device is characterized in that: the connecting component includes a lifting ring sleeved on the water distribution pipe, a vertical connecting rod is provided at the top of the lifting ring, a horizontal connecting plate is fixedly connected to the top of the vertical connecting rod, and the horizontal connecting plate is fixedly connected to the bottom of the sprinkler truck by multiple bolts.

[0006] The strip sprinkler system described above is characterized in that: the inlet pipe and the branch pipe are connected and manufactured as a single unit.

[0007] The above-mentioned strip sprinkler device is characterized in that: the inlet end of the water inlet pipe is provided with an internal thread, and the water inlet pipe is connected to the electromagnetic flow valve through a conversion joint with external threads at both ends; the outlet end of the water tank water supply pipe is provided with an internal thread, and the water tank water supply pipe is connected to the electromagnetic flow valve through a conversion joint with external threads at both ends.

[0008] The above-mentioned strip sprinkler system is characterized in that: a PLC controller is installed in the cab of the sprinkler truck, and the electromagnetic flow valve is controlled by the PLC controller. The beneficial effects of this utility model are that by setting equally spaced fan-shaped nozzles at the bottom of the water distribution pipe, the opening angle of the fan-shaped nozzles is determined according to the nozzle spacing and the height above the ground. The spray range of adjacent nozzles does not overlap with each other and forms a continuous strip-shaped spray water curtain, making the water flow distribution more uniform. An electromagnetic flow valve is installed on the pipeline connecting the water tank supply pipe and the water inlet pipe. The electromagnetic flow valve is used to regulate the spray flow of the sprinkler truck, which effectively avoids the problem of uneven water coverage caused by the local concentrated water volume of traditional single nozzles. It significantly improves the uniformity of the moisture content of the dam material before compaction in earth-rock dam construction.

Detailed Implementation

[0015] like Figures 1 to 4 As shown, this utility model includes a water distribution pipe 2 and an inlet pipe 1 located at the rear middle of the water distribution pipe 2 and connected to the water tank supply pipe 10. An electromagnetic flow valve 11 is installed on the pipe connecting the water tank supply pipe 10 and the inlet pipe 1. The water distribution pipe 2 is connected to the bottom of the sprinkler truck 12 via multiple connecting components. Multiple fan-shaped nozzles 4, evenly spaced along the length of the water distribution pipe 2, are installed at the bottom of the water distribution pipe 2. Each fan-shaped nozzle 4 has a nozzle opening 9, and the opening angle of the nozzle opening 9 is... Where L is the spacing between two adjacent fan-shaped nozzles 4, and H is the height of the spray nozzle 4 from the ground.

[0016] It should be noted that by setting equally spaced fan-shaped nozzles at the bottom of the water distribution pipe, the opening angle of the fan-shaped nozzles is determined according to the nozzle spacing and the height above the ground. The spray range of adjacent nozzles does not overlap with each other, and a continuous strip-shaped spray water curtain is formed, making the water flow distribution more uniform. An electromagnetic flow valve is installed on the pipeline connecting the water tank supply pipe and the water inlet pipe. The electromagnetic flow valve is used to regulate the spray flow of the sprinkler truck, which effectively avoids the problem of uneven water coverage caused by the local concentration of water spray from traditional single nozzles. It significantly improves the uniformity of the moisture content of the dam material before compaction in earth-rock dam construction.

[0017] In this embodiment, the connecting assembly includes a lifting ring 3 sleeved on the water distribution pipe 2, a vertical connecting rod 6 is provided on the top of the lifting ring 3, a horizontal connecting plate 7 is fixedly connected to the top of the vertical connecting rod 6, and the horizontal connecting plate 7 is fixedly connected to the bottom of the sprinkler truck 12 by multiple bolts 8.

[0018] In this embodiment, the water inlet pipe 1 and the water distribution pipe 2 are connected and manufactured as a single unit.

[0019] In this embodiment, the inlet end of the water inlet pipe 1 is provided with an internal thread 5, and the water inlet pipe 1 is connected to the electromagnetic flow valve 11 through a conversion joint with external threads at both ends. The outlet end of the water tank water supply pipe 10 is provided with an internal thread, and the water tank water supply pipe 10 is connected to the electromagnetic flow valve 11 through a conversion joint with external threads at both ends.

[0020] In this embodiment, a PLC controller is installed in the cab of the water sprinkler truck 12, and the electromagnetic flow valve 11 is controlled by the PLC controller.

[0021] When this utility model is used, the water distribution pipe 2 is laid out along the width direction of the sprinkler truck 12, and multiple fan-shaped nozzles 4 distributed at equal intervals along the length direction of the water distribution pipe 2 form a continuous strip-shaped spray water curtain. The spray range of adjacent nozzles does not overlap, making the water flow distribution more uniform and controlling the sprinkler truck 12 to move forward at a constant speed. By installing an electromagnetic flow valve at the water outlet of the sprinkler truck, the spray flow rate is adjusted in real time in conjunction with the continuous strip-shaped spray water curtain, which is of great significance for ensuring the quality of the dam project and extending its service life.
