Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to an assembled irrigation device for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are also called water engineering. Water is a precious resource that is indispensable for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. Irrigation is required in existing water conservancy projects, which is where irrigation devices are used.

[0003] Existing irrigation systems for watering seedlings cannot dynamically adjust their dimensions according to different environments. For example, cuttings and transplanted seedlings in the leaf-unrooted stage have high transpiration rates, requiring sprinkler irrigation to keep the branches and leaves moist and prevent dehydration and death. Therefore, irrigation for seedlings requires not only sprinkler irrigation of the stems and branches but also flood irrigation of the ground to meet the needs of rapid growth.

[0004] In the prior art, patent document CN213819214U discloses an assembled irrigation device for water conservancy projects. It features a connecting collar between the main irrigation pipe and the auxiliary irrigation pipe, allowing for threaded connection between the two pipes. This design facilitates assembly and allows for dynamic adjustment of the number of auxiliary pipes based on different working environments, thus providing adjustable irrigation length. However, this technical solution cannot spray water onto the branches and leaves of seedlings and is unsuitable for irrigating cuttings or transplanted seedlings during the leaf-developing, pre-rooted stage.

[0005] Patent document CN217160674U discloses an assembled irrigation device for water conservancy projects. During irrigation, a rotating nozzle at the top directly sprays water mist onto the trunks and leaves of seedlings above ground for direct absorption by the leaves. The irrigation head at the bottom penetrates underground to irrigate the root system, effectively reducing evaporation. However, when using this irrigation device, a conical drill bit is first installed at the lower end of the ground-penetrating irrigation seat, vertically inserted into the ground until the circular plate is fully in contact with the ground. Next, the ground-penetrating irrigation seat is lifted upwards from the ground, leaving a complete conical hole. The conical drill bit is removed from the lower end of the ground-penetrating irrigation seat, and the irrigation head is replaced and inserted back into the conical hole. Then, four positioning anchors are installed to stably position the ground-penetrating irrigation seat. Next, the number of extension water pipes is adjusted according to the height of fruit trees, shrubs, etc., followed by the installation of the rotating nozzle. Finally, a water inlet tee is connected to the water source via a water supply pipe. During installation, this irrigation device requires inserting the conical guide pipe into the ground, pulling it out, replacing the irrigation head, and then inserting both the conical guide pipe and the irrigation head back into the ground. Therefore, this device is rather cumbersome to use. Utility Model Content

[0006] The main purpose of this utility model is to provide an assembled irrigation device for water conservancy projects that is easy to install, can ensure that irrigation water effectively enters the soil, and can prevent water entering the soil from escaping through the gap between the cone tube and the soil.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: An assembled irrigation device for water conservancy projects includes a pressure plate, a concentric tapered tube fixed to the lower end of the pressure plate, the lower end of the tapered tube being sealed and pointed, an inlet control component and a spray component being provided at the upper end of the pressure plate, the inlet control component, the spray component and the tapered tube being connected, flat grooves being provided on both sides of the lower end of the tapered tube, a rotating tube being rotatably installed in the flat groove, the axis of the rotating tube being parallel to the axis of the tapered tube, an arc-shaped groove being provided on the vertical groove wall of the flat groove, the end of the rotating tube facing the axis of the tapered tube being located in the arc-shaped groove, the outer edge of the rotating tube contacting the groove wall of the arc-shaped groove, multiple outlet holes being provided on the end of the rotating tube facing the axis of the tapered tube, the multiple outlet holes being evenly distributed in the vertical direction, the groove wall of the arc-shaped groove blocking the outlet holes, a rib being fixed to the first end of the rotating tube away from the center of the tapered tube, the lower end of the end face of the rib away from the rotating tube being inclined towards the rotating tube, a channel being provided on the side wall of the tapered tube below the rotating tube, the channel connecting the rotating tube and the tapered tube.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1: Refer to Figures 1-7 As shown, an assembled irrigation device for water conservancy projects includes a pressure plate 1, a conical tube 2 is concentrically fixed at the lower end of the pressure plate 1, the lower end of the conical tube 2 is sealed and has a pointed end, and a water inlet control component and a spray component are provided at the upper end of the pressure plate 1, and the water inlet control component, the spray component and the conical tube 2 are connected.

[0030] The water inlet control assembly includes an upper pipe 5, with an inlet pipe 6 fixedly connected to its middle section. An upper valve 7 and a lower valve 8 are respectively installed above and below the inlet pipe 6 on the upper pipe 5. A connecting pipe 14 is fixedly attached to the upper end of the pressure plate 1, and the connecting pipe 14 is detachably and securely connected to the lower end of the upper pipe 5. Specifically, the connecting pipe 14 is threaded and sealed to the lower end of the upper pipe 5. The connecting pipe 14 is connected to the upper end of the tapered pipe 2.

[0031] The spray assembly includes a telescopic pipe 9, which comprises an outer pipe and an inner pipe. The lower end of the inner pipe is slidably and sealed within the outer pipe, and the upper end of the inner pipe extends above the outer pipe. A locking screw is threadedly connected to the upper end of the outer pipe, with one end of the locking screw abutting against the outer wall of the inner pipe. The lower end of the outer pipe is detachably and securely sealed to the upper end of the upper pipe 5. Specifically, the lower end of the outer pipe is threadedly and sealed to the upper end of the upper pipe 5.

[0032] A rotating nozzle 10 is installed at the upper end of the inner tube.

[0033] Both sides of the lower end of the tapered tube 2 are provided with flat grooves 13. A rotating tube 11 is rotatably installed in the flat groove 13. The axis of the rotating tube 11 is parallel to the axis of the tapered tube 2. The upper and lower ends of the rotating tube 11 are rotatably and sealingly connected to the tapered tube 2 above and below the flat groove 13, respectively.

[0034] An arc-shaped groove is provided on the vertical groove wall of the flat groove 13. The end of the rotating tube 11 facing the axis of the tapered tube 2 is located in the arc-shaped groove, and the outer edge of the rotating tube 11 is in contact with the groove wall of the arc-shaped groove.

[0035] The rotating tube 11 has multiple outlet holes 16 at one end facing the axis of the tapered tube 2. The multiple outlet holes 16 are evenly distributed in the vertical direction, and the groove wall of the arc-shaped groove blocks the outlet holes 16.

[0036] A rib 12 is fixed at the first end of the rotating tube 11 away from the center of the tapered tube 2. The lower end of the end face of the rib 12 away from the rotating tube 11 is inclined toward the rotating tube 11.

[0037] A channel 15 is provided on the side wall of the tapered tube 2 below the rotating tube 11, and the channel 15 connects the rotating tube 11 and the tapered tube 2.

[0038] During installation, the cone tube 2 is directly inserted into the soil. As the cone tube 2 is inserted into the soil, the outlet 16 on the rotating tube 11 is blocked by the wall of the arc-shaped groove, thus preventing soil from clogging the outlet 16.

[0039] During the process of inserting the cone tube 2 into the soil, the reinforcing bar 12 is inserted into the soil at the same time. When the lower end of the pressure plate 1 contacts the upper end of the ground, the pressure plate 1 and the cone tube 2 are rotated. During the rotation of the cone tube 2, the rotating pipe 11 is driven to revolve. Under the obstruction of the soil on the reinforcing bar 12, the rotating pipe 11 can rotate on its own axis. After the rotating pipe 11 rotates, the outlet hole 16 is rotated out from the arc groove. The water that has entered the cone tube 2 can be discharged through the channel 15, the rotating pipe 11 and the outlet hole 16 and then enter the soil.

[0040] After the cone tube 2 is inserted into the soil and rotated, the lower end of the upper tube 5 is threadedly sealed to the upper end of the connecting tube 14. Then, the lower end of the outer tube of the telescopic tube 9 is threadedly sealed to the upper end of the upper tube 5, and the inlet tube 6 is connected to the water pipe.

[0041] Water enters the upper pipe 5 through the inlet pipe 6. The water in the upper pipe 5 is divided into two streams: one stream flows upward through the telescopic pipe 9 and is sprayed from the rotating nozzle 10, wetting the support poles of the seedlings; the other stream flows out through the connecting pipe 14, cone pipe 2, channel 15, rotating pipe 11, and outlet hole 16, then enters the soil for seepage irrigation. Seepage irrigation reduces water evaporation, effectively conserving water resources.

[0042] The amount of water entering the cone pipe 2 and the telescopic pipe 9 can be controlled by controlling the upper valve 7 and the lower valve 8, respectively.

[0043] Loosening the locking screws allows adjustment of the overall height of the telescopic tube 9, which in turn allows adjustment of the height of the rotating nozzle 10, making it suitable for spraying and irrigating seedlings of different heights.

[0044] Example 2: Based on Example 1, referring to... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a sleeve 3 is concentrically fixed at the lower end of the pressure plate 1. The inner edge surface of the sleeve 3 is conical, and the diameter at the lower end of the inner edge surface of the sleeve 3 is larger than the diameter at the upper end. Multiple insertion holes are evenly distributed around the circumference of the pressure plate 1 on the outer side of the sleeve 3, and a drill rod 4 is inserted into the insertion hole.

[0045] In this embodiment, by setting a sleeve 3, and the inner edge of the sleeve 3 is a conical surface, after the sleeve 3 is inserted into the upper part of the soil, under the squeezing action of the inner edge of the sleeve 3 on the soil inside the sleeve 3, the soil inside the sleeve 3 can squeeze the outer edge of the conical tube 2, and the gap between the conical tube 2 and the soil can be sealed, thus preventing water discharged from the outlet 16 from seeping out through the gap between the soil and the outer edge of the conical tube 2.

[0046] By setting multiple drill rods 4, which are inserted into the soil, the stability of the device during operation can be further improved, and displacement or tilting caused by external forces (such as wind or water flow impact) can be reduced.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
