Description

Technical Field

[0001] This utility model relates to the field of irrigation technology in water conservancy projects, specifically a drip irrigation water outlet pile. Background Technology

[0002] For planting in the north, precise water control through drip irrigation outlets delivers water directly to the crop roots, reducing water waste.

[0003] However, in cold northern regions, when the ambient temperature is below 0℃, the residual water in the outlet pile is prone to freezing after the drip irrigation system stops working. Existing outlet piles prevent residual water from freezing by wrapping the outside with insulation cotton, but the insulation effect is limited. The freezing inside the outlet pile causes the internal pressure to increase, which in turn squeezes the related structure of the outlet pile and may cause damage to the outlet pile and related drip irrigation structure.

[0004] Therefore, this utility model provides a drip irrigation outlet pile to solve the above problems. Utility Model Content

[0014] Beneficial effects This utility model provides a drip irrigation water outlet post. Compared with the prior art, it has the following advantages: (1) A drip irrigation water outlet pile, wherein the drainage mechanism is in conjunction with an electromagnetic valve and a one-way exhaust valve. After drip irrigation, the water accumulated in the pile can be discharged remotely to avoid the residual water freezing at low temperature. In conjunction with the one-way exhaust valve, gas is introduced to assist drainage, ensuring that there is no dead corner water accumulation in the pile, eliminating the risk of freezing from the source. Then, through the insulation layer and heating layer, the ice layer attached to the pipe wall is removed, preventing the pipe from breaking due to the expansion of ice.

[0015] (2) A drip irrigation outlet pile, which forms a double filter through the second filter screen and the first filter screen to block impurities in the water from entering the one-way exhaust valve, avoids valve blockage and affects exhaust and drainage efficiency, and the upper and lower connecting parts are detachable, which makes it easy to disassemble and clean the filter screen regularly and maintain it simply.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please see Figure 1-4 A drip irrigation outlet pile includes a flange 1, a lower outlet pile connector 2 fixedly connected to the flange 1, an upper outlet pile connector 3, a first connector 4, a drainage mechanism and an ice removal mechanism, the drainage mechanism is disposed on the lower outlet pile connector 2, and the ice removal mechanism is disposed on the upper side of the drainage mechanism. The de-icing mechanism includes a heating layer 67, on which Velcro is provided. The heating layer 67 is fixedly connected to the outside of the lower water outlet connector 2 via Velcro. The outside of the heating layer 67 is wrapped with an insulation layer 66.

[0020] The first connector 4 is movably connected to the outside of the lower water outlet connector 2, the upper water outlet connector 3 is threadedly connected to the lower water outlet connector 2, the first connector 4 is threadedly connected to the upper water outlet connector 3, and a sealing ring is provided at the connection between the lower water outlet connector 2 and the upper water outlet connector 3.

[0021] A first connecting frame 65 is snapped onto the outer side of the upper water outlet connector 3. The insulation layer 66 is fixedly connected to the outer side of the upper water outlet connector 3 through the first connecting frame 65. A second connecting frame 68 is snapped onto the outer side of the lower water outlet connector 2. The lower side of the insulation layer 66 is fixedly connected to the outer side of the lower water outlet connector 2 through the second connecting frame 68. The outer layer of the inner rock wool of the insulation layer 66 is a waterproof membrane. The joints of the insulation layer 66 are sealed with butyl rubber waterproof adhesive and then sealed again with a detachable insulation sleeve. The detachable insulation sleeve is made of high-density polyethylene.

[0022] The upper water outlet pile connector 3 is threaded with a second connecting shell 64, the second connecting shell 64 is hinged with a first connecting shell 63, the first connecting shell 63 is fixedly connected with a controller shell 62, the controller shell 62 is provided with a solar panel 61, the inner side of the heating layer 67 is a self-regulating electric heating tape, the middle layer is a fiberglass cloth, and the outer layer is provided with Velcro.

[0023] The drainage mechanism includes a connecting pipe 53, which is fixedly connected to the upper water outlet pile connector 3, and a first filter screen 54 is threadedly connected to the outside of the connecting pipe 53.

[0024] A second filter screen 55 is threaded inside the connecting pipe 53. A one-way exhaust valve is fixedly connected inside the connecting pipe 53. A conveying pipe 51 is connected to the bottom side of the lower water outlet pile connector 2. A flow rate sensor is installed on the side of the conveying pipe 51. An electromagnetic valve 52 is installed at the end of the conveying pipe 51 away from the lower water outlet pile connector 2.

[0025] The lower side of the first connecting housing 63 houses a lithium battery, an inverter, and a protection device. The controller housing 62 contains a controller, which in turn contains a remote control module. The remote control module is used to remotely control the various moving parts on the water outlet pile. The remote control module utilizes existing technology, and technicians can select a suitable model based on its functions.

[0026] Working process: A preset threshold is detected by a temperature sensor, and the signal is transmitted to the controller and then wirelessly to a mobile phone. After drip irrigation is completed, the valve of the pipeline system connected to the water outlet is closed, and the solenoid valve 52 is opened remotely, allowing the water stored in the lower water outlet connector 2 to be discharged through the delivery pipe 51 and the solenoid valve 52. At the same time, gas is introduced through the one-way air valve in the connecting pipe 53, and the first filter screen 54 and the second filter screen 55 on both the inner and outer sides of the upper water outlet connector 3 filter out... The one-way air valve is free from clogging by debris, and it is detachable from the lower water outlet connector 2 and the upper water outlet connector 3. This allows for periodic removal of the first filter screen 54 and the second filter screen 55 from both the inside and outside of the upper water outlet connector 3 for easy cleaning. This prevents the first filter screen 54 and the second filter screen 55 from becoming clogged due to prolonged use, which would hinder the flow of gas into the upper water outlet connector 3 and consequently affect the discharge of water from the solenoid valve 52. This also prevents the water outlet and micro-irrigation connection structure from freezing and causing structural damage, thus avoiding any impact on irrigation.

[0027] If the water inside the lower water outlet connector 2 and the upper water outlet connector 3 is not drained in time, the temperature sensor will still detect that the low temperature has reached the preset value, resulting in internal ice formation. The temperature sensor will transmit the signal to the controller and transmit the information to the mobile phone via wireless remote control. The lithium battery will provide power to the heating layer 67, thereby heating the lower water outlet connector 2 and the ice formed on the inner walls of the lower water outlet connector 2 and the upper water outlet connector 3. This will cause the ice on the inner walls of the lower water outlet connector 2 and the upper water outlet connector 3 to fall off. In addition, the insulation layer 66 will keep the lower water outlet connector 2 and the upper water outlet connector 3 warm and prevent rainwater from damaging the heating layer 67.
