Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to a surface water irrigation device used in water conservancy projects. Background Art

[0002] Projects constructed to mitigate flood damage and develop and utilize water resources. Based on their intended purpose, they can be categorized as flood control projects, agricultural water conservancy projects, hydropower projects, waterway and port projects, water supply and drainage projects, environmental water conservancy projects, and coastal reclamation projects. Water conservancy projects that simultaneously serve multiple objectives, such as flood control, water supply, irrigation, and power generation, are called comprehensive water conservancy projects. Water conservancy projects require the construction of various hydraulic structures, such as dams, dikes, spillways, sluices, inlets, channels, ferries, rafts, and fishways, to achieve their objectives. Compared to other projects, water conservancy projects have the following characteristics: 1. Wide-ranging impacts. Water conservancy project planning is a component of river basin or regional water conservancy planning. The construction of a water conservancy project will have a significant impact on the surrounding environment, with both positive aspects such as promoting benefits and eliminating harm, as well as negative aspects such as flooding, inundation, resettlement, and relocation. Therefore, water conservancy project planning must take into account the overall situation of the river basin or region, taking a comprehensive approach to minimize adverse impacts and achieve optimal economic, social, and environmental outcomes. ② Water conservancy projects are generally large-scale, require significant investment, are technically complex, and require long construction periods. An irrigation system refers to the entire set of facilities within an irrigation project. It comprises three components: a water source (river, reservoir, or well, etc.) and channel structures. The water transmission system, which draws water from the source and transports it to the irrigation area, includes channels or pipelines and the tunnels, aqueducts, culverts, and inverted siphons that flow through them; a water distribution system, which distributes water within the irrigation area, includes channels at all levels within the irrigation area, as well as sluice gates, diversion gates, and dams that control and distribute water; and temporary channels within the fields.

[0003] The application number is 202011419446.X, which discloses an irrigation device, including a water pipe buried underground, a detachable irrigation rack at the upper end of the water pipe, and the irrigation rack includes a connecting rod connected to the water pipe, and a group of fixed water pipes and a group of regulating water pipes are symmetrically provided on the upper ends of the connecting rods. A number of water outlet holes are opened on the fixed water pipes and the regulating water pipes, and a valve is provided on the water pipe. When the present invention is used, the irrigation rack is screwed onto the water pipe, and the fixed water pipe is vertically arranged corresponding to the long strip area, and the regulating water pipe is parallel to the long strip area and reasonably adjusted according to its length. The valve is opened and the corresponding area is irrigated through the water outlet hole. In this way, it is convenient to automatically adjust the irrigation of areas of any shape and effectively improve the irrigation effect.

[0004] An irrigation device disclosed in the above document has the following defects: when the water pressure of the irrigation device is too high during irrigation, the water flow pressure in the pipeline will suddenly increase, causing the pipeline wall to crack or directly explode, resulting in a waste of water resources.

[0005] It can be seen from this that the existing irrigation device cannot solve the problem of excessive pressure when spraying crops. It is necessary to improve the existing deficiencies and provide a surface water irrigation device for water conservancy projects. Utility Model Content

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a surface water irrigation device for water conservancy projects, comprising a water delivery pipe and an upper branch pipe, and is characterized in that the upper branch pipe is fixedly installed on the left end of the water delivery pipe, a pipe opening is provided inside the body of the water delivery pipe, a lower branch pipe is fixedly installed on the right end of the water delivery pipe, a pressure relief port is fixedly installed on the right end of the lower branch pipe, and a sealing pipe is fixedly installed on the top end of the lower branch pipe.

[0008] Furthermore, there are six irrigation ports that are wide inside and thin outside on the main body of the upper branch pipe, and each of the six irrigation ports is fixedly installed on the outer wall of the upper branch pipe. The six irrigation ports are irrigation ports whose inner diameters gradually decrease from the inside to the outside.

[0009] Furthermore, there is a No. 1 threaded groove on the upper part of the upper branch pipe, and a No. 1 threaded column is fixedly installed inside the irrigation port with a wide inside and a thin outside. The bottom of the No. 1 threaded column is fixedly connected to the pressure block and the top is fixedly connected to the No. 1 fixed column, and the top surface of the No. 1 fixed column is fixedly installed with a fixed top cover.

[0010] Furthermore, a water inlet is fixedly installed inside the water supply pipe, a lower branch pipe is fixedly installed at the lower part of the water inlet, a pressurized water pipe exists inside the lower branch pipe, a valve stem is fixedly installed inside the pressurized water pipe, and a sealing pipe is fixedly installed on the bottom surface of the lower branch pipe.

[0011] Furthermore, a pressure relief spring column is fixedly installed inside the sealing pipe, the pressure relief spring column is fixedly connected to the valve stem, and a pressure relief spring is fixedly installed on the outer wall surface of the pressure relief spring column.

[0012] Furthermore, a No. 2 thread groove is fixedly installed inside the sealing pipe, and the No. 2 thread groove and the No. 2 thread column are used in conjunction with each other, and the thread groove on the inner wall of the No. 2 thread groove coincides with the thread on the outer wall of the No. 2 thread column.

[0014] Furthermore, the water inlet of the water supply pipe is connected to the conical filter screen through a clamping part. There are conical filter mesh holes on the conical surface of the conical filter screen. The rear end of the conical filter screen is fixedly installed with a purification net. There are purification holes inside the purification net to further filter the water quality of the water inlet pipe.

[0015] The utility model has the following beneficial effects:

[0016] (1) The utility model fixes the pressure relief spring and valve stem inside the lower branch pipe, and can reduce the water pressure from the pressure relief port when the water pressure inside the water pipeline is too high, thereby preventing the pipeline from suddenly increasing the water flow pressure, causing the pipeline wall to crack, or directly exploding, resulting in a waste of water resources.

[0017] (2) The utility model provides a boost irrigation port with an inner diameter gradually decreasing from the inside to the outside on the inner wall of the upper branch pipe. When the water on the inner wall of the upper branch pipe is sprayed out from the wide inside and thin outside irrigation port, the inner diameter of the limiting column gradually decreases from the inside to the outside, so that the dynamic pressure of the sprayed water is further enhanced. Therefore, when the water is sprayed out from the wide inside and thin outside irrigation port, the pressurized high-speed water flow will also achieve the farthest spraying distance, which can control the distance of the water spraying range.

[0018] (3) The utility model clamps the conical filter screen at the water inlet, so that the conical filter screen can filter out impurities and particles in the liquid, ensuring the cleanliness of the liquid. The conical filter screen can withstand high pressure, has good filtering effect, and is not easily clogged. The conical filter screen has a simple structure and is easy to install and maintain. The conical filter screen has a long service life and can maintain good filtering effect after repeated use.
