Description

Technical Field

[0001] This utility model relates to the field of greening maintenance technology, specifically a drip irrigation pipe for greening irrigation. Background Technology

[0002] Drip irrigation pipes are generally divided into main pipes and branch pipes. At the connection between the main pipe and the branch pipes, the flow channel is narrow. Impurities such as silt, algae, suspended solids, and undissolved fertilizer particles in the irrigation water can easily accumulate in the flow channel when flowing through the branch pipe, causing blockage. This will hinder the normal delivery of irrigation water, reduce the water output of some branch pipes or drippers, or even stop the flow of water. As a result, crops in the irrigated area cannot receive an even supply of water and nutrients, affecting the uniformity of crop growth, resulting in uneven plant size and yield.

[0003] Therefore, in order to solve the problem of easy blockage at the connection between the main pipe and the branch pipe of drip irrigation pipe, it is necessary to propose a drip irrigation pipe for greening irrigation. Utility Model Content

[0004] The purpose of this utility model is to provide a drip irrigation pipe for greening irrigation. By setting a detachable filter between the main pipe and the branch pipe, impurities in the irrigation water can be effectively filtered, preventing blockage at the connection of the drip irrigation pipe, ensuring normal delivery of irrigation water, so that crops can obtain water and nutrients evenly, improving growth uniformity and yield. Moreover, when the filter is blocked, it can be cleaned by disassembling the filter cartridge, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A drip irrigation pipe for greening irrigation, characterized in that it includes a main pipe, a branch pipe connected to the main pipe, and a filter that can be detachably installed between the main pipe and the branch pipe;

[0007] The filter consists of an outer cylinder and a filter cartridge. The filter cartridge is detachably placed inside the outer cylinder, and the outer diameter of the filter cartridge is smaller than the inner diameter of the outer cylinder. A retaining ring for fixing the filter cartridge is provided on the inner wall of the outer cylinder.

[0008] The filter cartridge is surrounded by screen bars, which are arranged along the axial direction of the filter cartridge. A cleaning plate is slidably connected to the filter cartridge via the screen bars. By sliding the cleaning plate, impurities attached to the screen bars and the inner wall of the filter cartridge can be scraped off.

[0009] Preferably, the outer cylinder is provided with a water inlet and a water outlet. The water inlet is connected to the main pipe through a pipe interface, and the water outlet is connected to the branch pipe.

[0010] Preferably, the inlet and pipe interface, the outlet and branch pipe, and the outer cylinder and filter cylinder are all connected by flanges as connecting components.

[0011] Preferably, one end of the filter cartridge is provided with a flange cover, and a pull ring is installed on the outside of the flange cover.

[0012] Preferably, the outer diameter of the cleaning plate is the same as the inner diameter of the outer cylinder.

[0013] Preferably, the cleaning plate is made of rubber.

[0014] Preferably, the diameter of the main pipe is larger than that of the branch pipe.

[0015] Preferably, the end of the branch pipe is equipped with a dripper for watering greenery.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This drip irrigation pipe for greening irrigation can effectively filter impurities such as mud, algae, suspended solids and undissolved fertilizer particles in the irrigation water by installing a detachable filter between the main pipe and the branch pipe. This prevents these impurities from accumulating at the connection between the main pipe and the branch pipe, thereby preventing blockage at the connection of the drip irrigation pipe, ensuring the normal delivery of irrigation water, ensuring that crops can receive water and nutrients evenly, and improving growth uniformity and yield.

[0018] 2. When cleaning the filter of this drip irrigation pipe for greening irrigation, the filter cartridge can be disassembled and the cleaning plate can be slid along the screen bar. During the sliding process, impurities such as mud, algae, suspended solids and undissolved fertilizer particles attached to the inner wall of the filter cartridge and the screen bar can be scraped off, thereby effectively cleaning the filter cartridge, preventing the accumulation of impurities that may cause filter blockage, and maintaining the filter's good filtration performance.

[0024] Please see Figures 1-2 A drip irrigation pipe for greening irrigation includes a main pipe 1, a branch pipe 2 connected to the main pipe 1, and a filter 3 that can be detachably installed between the main pipe 1 and the branch pipe 2. The diameter of the main pipe 1 is larger than the diameter of the branch pipe 2, and the end of the branch pipe 2 is equipped with a dripper for watering greenery.

[0025] Among them, main pipe 1 serves as the main delivery pipe of the entire drip irrigation system, responsible for delivering water from the headworks (such as water pump equipment);

[0026] Branch pipe 2 is connected to main pipe 1, which plays the role of distributing and delivering water to each dripper, thereby achieving precise irrigation of green crops.

[0027] The filter 3 is detachably installed between the main pipe 1 and the branch pipe 2. This design facilitates regular maintenance, cleaning, or replacement of the filter 3, ensuring the stability of the filtration effect. The core function of the filter 3 is to filter the irrigation water, remove impurities from the water, and effectively prevent impurities from accumulating at the connection between the main pipe 1 and the branch pipe 2, avoiding blockage problems, thereby ensuring the long-term stable operation and irrigation efficiency of the drip irrigation system.

[0028] Please see Figure 3 The filter 3 consists of an outer cylinder 31 and a filter cartridge 32 placed inside the outer cylinder 31.

[0029] The outer cylinder 31 serves as a support and protection element, providing a structural frame for the entire filter 3, enabling it to be stably installed between the main pipe 1 and the branch pipe 2, and to withstand certain water pressure and external impact.

[0030] The filter cartridge 32, placed inside the outer cylinder 31, is the core component of the filter. Its surface usually has fine sieve bars 321, which can effectively intercept impurities in the irrigation water, such as mud, algae, suspended solids, and undissolved fertilizer particles, allowing only clean water to pass through, thereby achieving the function of filtering irrigation water, preventing impurities from entering the branch pipe 2 and causing blockage, and ensuring the normal operation of the drip irrigation system.

[0031] Please see Figures 2-3 The outer cylinder 31 is provided with an inlet 311 and an outlet 312. The inlet 311 is connected to the main pipe 1 through the pipe interface 11, and the outlet 312 is connected to the branch pipe 2.

[0032] The inlet 311 is connected to the main pipe 1 through the pipe interface 11, so that irrigation water can enter the filter cylinder 32 in the outer cylinder 31 from the main pipe 1. The outlet 312 is connected to the branch pipe 2. The water filtered by the filter 3 flows into the branch pipe 2 through the outlet 312 and then flows to the dripper to irrigate the green crops.

[0033] Please see Figure 4 The filter cylinder 32 is surrounded by screen bars 321, which are arranged along the axial direction of the filter cylinder 32. The filter cylinder 32 is slidably connected to the cleaning plate 322 via the screen bars 321.

[0034] Among them, the screen bar 321 can effectively intercept impurities in irrigation water, such as mud, algae, suspended solids and undissolved fertilizer particles, and prevent these impurities from entering the branch pipe 2 through the filter cartridge 32, thereby playing a filtering role.

[0035] Meanwhile, the filter cartridge 32 is slidably connected to the cleaning plate 322 via the screen bar 321. The cleaning plate 322 can slide along the direction of the screen bar 321. By sliding the cleaning plate 322, the impurities attached to the screen bar 321 and the inner wall of the filter cartridge 32 can be scraped off, thereby cleaning the filter cartridge 32, preventing the accumulation of impurities from clogging the filter 3, and ensuring the filtration effect of the filter 3.

[0036] Please see Figure 2 Flanges are used as connecting components to connect the inlet 311 to the pipe interface 11, the outlet 312 to the branch pipe 2, the outer cylinder 31 and the filter cylinder 32.

[0037] The flanges are usually equipped with gaskets. When connecting, the gaskets are evenly compressed between the two flanges by tightening the bolts, thus forming a reliable sealing barrier and effectively preventing irrigation water from leaking at the connection.

[0038] Furthermore, the flange design can withstand certain water pressure and mechanical stress, ensuring that all connection parts remain stable during system operation. When irrigation water flows in the drip irrigation pipe, it generates a certain pressure, and the flange connection can firmly and tightly connect the various components, preventing the connection from loosening due to water pressure changes or external impacts.

[0039] Please see Figure 4 The filter cartridge 32 is provided with a flange cover at one end, and a pull ring 323 is installed on the outside of the flange cover.

[0040] When the filter cartridge 32 needs to be cleaned or replaced, simply remove the flange cover and pull the pull ring 323 to easily remove the filter cartridge 32, which greatly saves maintenance time and improves work efficiency.

[0041] Please see Figure 3 The outer diameter of the filter cartridge 32 is smaller than the inner diameter of the outer cylinder 31, and a retaining ring 313 for fixing the filter cartridge 32 is provided on the inner wall of the outer cylinder 31.

[0042] The function of the retaining ring 313 is to firmly fix the filter cartridge 32 inside the outer cylinder 31, preventing the filter cartridge 32 from shifting or shaking due to the impact of water flow, and ensuring the stable operation of the filter 3.

[0043] Please see Figures 3-4 The outer diameter of the cleaning plate 322 is the same as the inner diameter of the outer cylinder 31, and the cleaning plate 322 is made of rubber.

[0044] The outer diameter of the cleaning plate 322 is the same as the inner diameter of the outer cylinder 31, and it is made of rubber, so that the cleaning plate 322 can fit tightly against the inner wall of the outer cylinder 31. When the drip irrigation pipe is working, the cleaning plate 322 is located at the end of the filter cartridge 32 under the impact of irrigation water and fits tightly against the inner wall of the outer cylinder 31 to achieve the effect of a sealing ring.

[0045] Furthermore, the rubber cleaning plate 322 and the screen bar 321 are tightly fitted together, which can not only effectively scrape off the impurities attached to the inner wall of the filter cylinder 32 and the screen bar 321, but also ensure the uniformity and thoroughness of the cleaning process. This tight fit reduces cleaning dead corners.

[0046] Working Principle: This drip irrigation pipe for landscaping irrigation works by first drawing water from the headworks (such as a water pump) into the main pipe 1. The water flows along the main pipe 1, reaching the pipe interface 11, and then enters the filter 3 through the inlet 311. After entering the outer cylinder 31, the water flows towards the filter cartridge 32 located inside. Under the impact of the water flow, the cleaning plate 322 is pressed against the end of the filter cartridge 32. Because the surface of the filter cartridge 32 is surrounded by screen bars 321, it can effectively filter water. Impurities in the irrigation water, such as silt, algae, suspended solids, and undissolved fertilizer particles, are blocked inside the filter cylinder 32 as the water flows through it. The clean water passes through the screen bar 321 into the cavity between the filter cylinder 32 and the outer cylinder 31, and finally flows out from the outlet 312 into the branch pipe 2. It continues to flow to the end of the branch pipe 2 and finally reaches the dripper installed at the end of the branch pipe 2. The dripper drips the water evenly into the soil near the greening crops in the form of small drops, thus achieving precision irrigation.

[0047] During the operation of the drip irrigation pipe, impurities will gradually accumulate on the screen bars 321 on the surface of the filter cartridge 32 and inside the filter cartridge 32, resulting in a decrease in filtration effect. At this time, the flange cover is removed, and the filter cartridge 32 is pulled outward by the pull ring 323 to remove the filter cartridge 32. The cleaning plate 322 is then slid along the screen bars 321 so that the cleaning plate 322 can effectively scrape off the impurities attached to the inner wall of the filter cartridge 32 and the screen bars 321, thereby cleaning the filter cartridge 32, preventing the accumulation of impurities from clogging the filter 3, and ensuring the filtration effect of the filter 3.
