Abstract
Description
[0001] The present invention relates to the technical field of irrigation devices for backfilling work, in particular an irrigation device for backfilling with riprap materials.
[0002] The construction process of embankment dams releases large quantities of dust, fumes, and other fine particulate matter. If these dust particles remain in the air for extended periods, they form harmful substances such as PM2.5, which can negatively impact human health and the ecological balance. To protect the environment and human health, a range of environmental protection measures are necessary during the construction of embankment dams. One such measure is the irrigation of the installed embankment materials.
[0003] Current irrigation systems for backfilling with aggregate typically consist of a water tank, water lines, and nozzles. The tank can be mounted on a vehicle, and the water is transported through the lines to the nozzles and sprayed. However, conventional nozzles are prone to clogging and offer only limited adjustment of the spray angle. Furthermore, the water lines rely heavily on electric or fossil fuel power, making them unsuitable for use on remote construction sites with limited electricity supply. With this in mind, experts in the field have developed an irrigation system for backfilling with aggregate to address these issues.
[0004] The object of the present invention is to provide a sprinkler system for backfilling with aggregate materials in order to solve the problems described in the above-mentioned background technology.
[0005] To fulfill the above-mentioned task, the invention offers the following technical solutions: Irrigation device for backfilling with aggregate materials, comprising a base plate with a water tank attached to its upper surface, a cover plate being attached to the upper surface of the water tank, and a water inlet pipe being attached to the cover plate, an end of a water outlet pipe being arranged on one side of the bottom of the water tank, a control valve being attached to the water outlet pipe, an end of a crossbar being arranged on the other side of the bottom of the water tank, and the other end of the crossbar being connected to an outer wall of a mounting sleeve, a rotary pipe being rotatably connected within the mounting sleeve, and a fastening unit being attached to the upper surface of the mounting sleeve, the angle of the rotary pipe being adjustable within the mounting sleeve and being secured by the fastening unit.and wherein the other end of the water outlet pipe is connected to one end of the rotary pipe by a continuous matching swivel joint, the other end of the rotary pipe is closed, and wherein several drainage pipes are fitted at equal intervals at the bottom of the rotary pipe, and a rotary nozzle unit is fitted at the bottom of the drainage pipe.
[0006] In a further embodiment of this invention, several mounting holes are evenly arranged on the circumferential surface of the part of the rotary tube that is arranged in the mounting sleeve, wherein a cylindrical hole is provided on the top of the mounting sleeve, and wherein the fastening unit comprises the following: a locking pin that is installed in the cylindrical hole, a handle that is attached to the upper end of the locking pin, and a spring element that is arranged on the upper section of the locking pin, wherein the upper and lower ends of the spring element are each connected to the underside of the handle and the outer wall of the top of the mounting sleeve, and the underside of the locking pin is inserted into the mounting hole at the corresponding position.
[0007] In a further embodiment of this invention, a support rod is arranged in the lower interior of the drainage pipe, wherein the rotary nozzle unit comprises a hemispherical nozzle and a rotary rod, and the center of the rotary rod is rotatably connected to the center of the support plate, with turbine blades being connected to the top of the rotary rod, and the bottom of the rotary rod being connected to the inner upper wall of the hemispherical nozzle via a connecting rod, wherein the top of the hemispherical nozzle slides against the bottom of the drainage pipe.
[0008] In a further embodiment of this invention, several vortex guide plates are arranged evenly distributed on the upper inner wall of the drainage pipe.
[0009] In a further embodiment of this invention, vertical grooves are provided on the inner walls of both sides of the part of the water tank that is located near the water outlet pipe, with several filter plates being inserted and attached in the water tank via the vertical grooves.
[0010] The present invention has the following advantageous features: The sprinkler system for backfilling with aggregate materials achieves highly efficient and uniform water application through its integrated mechanical design. The combination of a water tank and a swiveling rotary tube, in conjunction with centrifugally driven rotary nozzle units, allows for flexible adjustment of the spray area and angle according to the construction requirements. This ensures homogeneous moistening of the aggregate material surface. The rotary nozzle unit utilizes the centrifugal force of the flow for automatic rotation, thereby avoiding the clogging problems of conventional fixed nozzles and increasing water utilization efficiency. Furthermore, the entire structure operates according to a purely mechanical drive principle; the mounting sleeve and crossbar provide stable support.Irrigation is achieved solely through gravity, without any electrical drive power, making it particularly suitable for use in typical, energy-free construction site environments. At the same time, the modular design of the water inlet and outlet pipes allows for quick disassembly, assembly, and maintenance access. The water inlet pipe on the top plate, together with the control valve at the base, forms a closed water circulation system that combines user-friendly operation with water-saving environmental friendliness. This effectively eliminates the technical weaknesses of conventional irrigation systems—uneven coverage, high energy consumption, and increased susceptibility to malfunctions—significantly improving its practical usability.

It is sufficient,that the sealing ring 26 does not impede the rotation between the rotary pipe 10 and the water outlet pipe 5; in this embodiment, the water outlet pipe 5 is U-shaped, and the outer diameter of the water outlet pipe 5 corresponds to the inner diameter of the rotary pipe 10, the other end of the rotary pipe 10 being closed, and the length of the rotary pipe 10 being able to be determined according to requirements, wherein several drainage pipes 11 are attached at equal intervals to the bottom of the rotary pipe 10, and a rotary nozzle unit 12 is attached to the bottom of the drainage pipe 11, which is driven by the centrifugal force of the water flow, thereby setting the nozzles into rotation for irrigation.
[0013] As in Fig. 1 and Fig. As shown in Figure 4, several mounting holes 18 are evenly spaced on the circumferential surface of the outer wall of the part of the rotary tube 10 that is arranged in the mounting sleeve 8, a cylindrical hole 19 being provided on the top of the mounting sleeve 8, and the fastening unit 9 comprising: a locking pin 20 that is fitted in the cylindrical hole 19, a handle 21 that is attached to the upper end of the locking pin 20, and a spring element 22 that is arranged on the upper section of the locking pin 20, the upper and lower ends of the spring element 22 being connected, respectively, to the underside of the handle 21 and the outer wall of the top of the mounting sleeve 8, and the underside of the locking pin 20 being inserted into the mounting hole 18 at the appropriate position, the spring element 22 being selected as a spring.
[0014] As in Fig. 1 and Fig. As shown in Figure 5, a support rod 14 is arranged in the lower interior of the drainage pipe 11, and the rotary nozzle unit 12 comprises a hemispherical nozzle 28 and a rotary rod 15, wherein the center of the rotary rod 15 is rotatably connected to the center of the support plate, wherein turbine blades 16 are connected to the top of the rotary rod 15, and the bottom of the rotary rod 15 is connected via a connecting rod 17 to the inner upper wall of the hemispherical nozzle 28, wherein the top of the hemispherical nozzle 28 slides against the bottom of the drainage pipe 11, and several spray openings are evenly distributed on the hemispherical nozzle 28, and several vortex guide plates 13 are evenly distributed on the upper inner wall of the drainage pipe 11, wherein the water flow forms a vortex after passing the vortex guide plates 13 to improve the flushing effect on the turbine blades 16.
[0015] Design II: As in Fig. 1, Fig. 2 to Fig. As shown in Figure 3, and based on the first embodiment, vertical grooves 23 are provided on the inner walls of both sides of the part of the water tank 2 that is located near the water outlet pipe 5, and several filter plates 24 are inserted and attached in the water tank 2 via the vertical grooves 23; different types of filter plates 24, such as activated carbon filter plates, can be used in combination; a filter frame 27, made of a mesh frame and serving for pre-filtering the water, is attached to the underside of the cover plate 3 and directly below the water inlet pipe 4 via bolts.
[0016] Operating principle: In use, the base plate 1 is mounted on the rear or side of the carrier vehicle. If the top of the aggregate needs to be watered, the swivel pipe 10 is installed on the rear of the carrier vehicle. For watering the sides of the aggregate (sloping sides of trapezoidal layers of aggregate), it is sufficient to install the swivel pipe 10 on the side of the carrier vehicle. The carrier vehicle moves the water tank 2 to the water filling point. Water is filled into the water tank 2 via the water inlet pipe 4, and the control valve 6 is closed. When the device reaches the watering location, the locking pin 20 is raised using the handle 21. After the angle of the swivel pipe 10 has been set, the handle 21 is released. The spring element 22 pulls the lower part of the locking pin 20 into the corresponding socket 18, thus fixing the angle of the swivel pipe 10.The control valve 6 is then opened, and under the influence of its own weight, the water flows through the water outlet pipe 5 into the rotary pipe 10 and is directed via the drainage pipe 11 to the rotary nozzle unit 12. The water flow strikes the turbine blades 16, which then drive the hemispherical nozzle 28 to rotate. The combination of water flow pressure and the centrifugal force of the rotating hemispherical nozzle 28 expels the water from the spray openings. The filtration of the water by the filter plates 24 and the effect of the centrifugal force from the rotation of the hemispherical nozzle 28 effectively reduce clogging of the spray openings. The water flow rate can be regulated via the control valve 6, thereby controlling the spray area of the hemispherical nozzle 28.
