Description

Technical Field

[0001] This utility model relates to the field of irrigation equipment, specifically an adjustable water-saving drip irrigation device for urban landscaping. Background Technology

[0002] With the continuous acceleration of urbanization, urban greening has become an increasingly important measure to improve the quality of the urban ecological environment and beautify the urban landscape. Various flowers, trees and shrubs are widely planted in urban parks, roadsides, squares and other areas, which not only create a comfortable and pleasant living environment for urban residents, but also play an important role in purifying the air, regulating the climate and reducing noise.

[0003] To meet the water requirements of different plants at different growth stages in urban landscaping, a variety of drip irrigation devices have emerged on the market, such as portable drip irrigation bags and micro-sprinklers with good humidification effects. These devices usually have adjustable functions, which can flexibly adjust the drip irrigation speed according to the water requirements of the plants to achieve water conservation, improve irrigation efficiency to a certain extent, and reduce water waste.

[0004] However, while existing drip irrigation bags are quite portable, most are fixed to tree trunks with ropes. When the drip irrigation bag is filled with water, the weight increases and it is easy for it to slip off. In severe weather such as strong winds, the drip irrigation bag is prone to shaking or even falling off, which not only reduces the service life of the drip irrigation device but also increases the labor maintenance cost. Therefore, an adjustable water-saving drip irrigation device for urban landscaping is proposed. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an adjustable water-saving drip irrigation device for urban landscaping, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable water-saving drip irrigation device for urban landscaping, comprising a drip irrigation bag, a slidably mounted band on the top of the drip irrigation bag, a fixing block fixedly mounted on the outer wall of the band, and a telescopic rod fixedly mounted on the inner wall of the fixing block, a claw fixedly mounted on one end of the band, and a sleeve corresponding to the claw fixedly mounted on the other end for engaging the two ends of the band; The telescopic rod includes an outer tube and a ground stake, wherein the ground stake is slidably installed on the inner wall of the outer tube, and a pressure block is fixedly installed at the top of the outer tube for applying pressure to the telescopic rod. The ground stake is provided with a locking mechanism for locking the telescopic rod in its stretched or retracted state, and the bottom end of the ground stake is designed as a sharp structure.

[0007] By adopting the above technical solution, the clamps and sleeves work together to allow the bands to engage quickly, thus significantly shortening the installation time. This enables the drip irrigation bag to be quickly fixed to the tree trunk. The pressure block, in conjunction with the telescopic rod, allows the ground nails to be quickly inserted into the soil by manual pressure, without the need for additional tools. The ground nails are equipped with a locking mechanism to lock the telescopic rod in its extended or retracted state. The locking mechanism can instantly fix the extended or retracted state. A single person can complete the length adjustment and positioning of the telescopic rod, greatly simplifying the installation process and meeting the needs of rapid deployment in greening scenarios.

[0008] Furthermore, a water inlet is fixedly installed on the outer wall of the drip irrigation bag, and the end of the water inlet is designed with an elastic material so that it is closed in a natural setting. An adjustment tube is fixedly installed on the outer wall of the drip irrigation bag to adjust the drip irrigation speed.

[0009] By adopting the above technical solution, users only need to manually pinch both sides to open the pipe when filling it with water, and it will automatically close after the water pipe is pulled out. This eliminates the need for additional sealing components to prevent water leakage, thereby effectively reducing water evaporation and seepage.

[0010] Furthermore, the bottom of the drip irrigation bag is provided with a shaping ring, and the shaping ring has a semi-circular design.

[0011] By adopting the above technical solution, the shaping ring, through its own rigid structure, can maintain the semi-circular shape at the bottom of the drip irrigation bag after it is filled with water, preventing the bag from shifting due to expansion caused by increased water volume, thereby extending the service life of the device.

[0012] Furthermore, multiple sets of claws and sleeves are provided on the band, and the thickness of the claws is greater than the thickness of the sleeves, and the outer diameter of the claw ends is greater than the inner diameter of the sleeves.

[0013] By adopting the above technical solution, the length of the hoop can be adjusted according to the size of different tree trunks, thereby improving the versatility of the hoop.

[0014] Furthermore, the locking mechanism includes a first thread segment and a second thread segment, wherein the first thread segment is adjacent to the sharp part of the ground nail, and the second thread segment is located at the top of the ground nail. The bottom of the inner wall of the outer sleeve is provided with a fixing interface corresponding to the first thread segment and the second thread segment. The outer sleeve and the ground nail cooperate with each other to lock the second thread segment and the fixing interface threadedly when the telescopic rod is in the stretched state, and lock the first thread segment and the fixing interface threadedly when the telescopic rod is in the retracted state.

[0015] By adopting the above technical solution, the connection and locking are achieved through the No. 1 threaded section and the No. 2 threaded section and the fixed interface. Stability can be maintained when the ground nail is retracted and stored and stretched and fixed. The extension and retraction of the telescopic rod can be completed without any tools, thus adapting to the needs of rapid installation and storage in garden scenes and greatly reducing the operation threshold.

[0016] In summary, the present invention has the following main advantages: This invention features a telescopic rod composed of ground nails and an outer sleeve. With the help of a pressure block, the ground nails are quickly inserted into the soil. Combined with the clamping claws of the hoop and the engaging design of the sleeve, it quickly and effectively secures the drip irrigation bag to the tree trunk and the ground, solving the problem of traditional drip irrigation bags easily slipping off. The ground nail fixing method is adaptable to various terrains, and the hoop's length can be adjusted according to the trunk's thickness. The rubber surface of the hoop prevents injury to the trunk, ensuring both effective fixation and tree protection. It is suitable for urban landscaping. The telescopic rod, through the two-section threaded structure of the ground nails and the fixing interface of the outer sleeve, allows for rapid extension and locking. The shaping ring at the bottom of the drip irrigation bag maintains the shape of the bottom when filled with water, reducing the impact of large deformations on drip irrigation stability. The coordinated components enhance overall reliability and extend service life. The elastic water inlet can be manually opened and closed without tools, making water filling simple and providing excellent sealing. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Example 1 An adjustable water-saving drip irrigation device for urban landscaping, such as Figure 1-4 As shown, the device includes a drip irrigation bag 1, with a slidable band 2 on the top of the drip irrigation bag 1. The side of the band 2 closest to the tree trunk is made of rubber to prevent the drip irrigation bag 1 filled with water from damaging the tree trunk. A fixing block 23 is fixedly installed on the outer wall of the band 2, and a telescopic rod is fixedly installed on the inner wall of the fixing block 23. A claw 21 is fixedly installed at one end of the band 2, and a sleeve 22 corresponding to the claw 21 is fixedly installed at the other end for locking the two ends of the band 2. Through the cooperation of the claw 21 and the sleeve 22, the band 2 can be quickly locked, thereby significantly shortening the installation time and enabling the drip irrigation bag 1 to be quickly fixed to the tree trunk. The telescopic pole includes an outer sleeve 3 and a ground nail 32. The ground nail 32 is slidably installed on the inner wall of the outer sleeve 3, and a pressure block 31 is fixedly installed at the top of the outer sleeve 3 for applying pressure to the telescopic pole. By using the pressure block 31 in conjunction with the telescopic pole, the ground nail 32 can be quickly inserted into the soil by manual pressure without additional tools. The ground nail 32 is equipped with a locking mechanism for locking the telescopic pole in its extended or retracted state. The locking mechanism can fix the extended or retracted state in an instant. A single person can complete the length adjustment and positioning of the telescopic pole, which greatly simplifies the installation process and meets the needs of rapid deployment in greening scenarios. The bottom end of the ground nail 32 is designed with a sharp structure to reduce the contact area between the bottom end and the soil, reducing the force required for insertion and making it easier to quickly drive the ground nail 32 deep into the soil.

[0022] Please see Figure 1-4 The drip irrigation bag 1 has a water inlet 11 fixedly installed on its outer wall. The end of the water inlet 11 is designed with an elastic material so that it is closed in a natural setting. This allows the user to open the bag by simply pinching the two sides when filling it with water. The bag will automatically close after the water pipe is pulled out, preventing leakage without the need for additional sealing components. This effectively reduces water evaporation and seepage. The drip irrigation bag 1 also has an adjustment pipe 12 fixedly installed on its outer wall to adjust the drip irrigation speed. This allows for direct control of the drip irrigation speed and flexible adjustment of the water output based on the tree species, growth stage, or soil moisture, achieving "on-demand irrigation" and improving water-saving efficiency.

[0023] Please see Figure 1-4 The bottom of the drip irrigation bag 1 is provided with a shaping ring 13, which is semi-circular in design. The shaping ring 13, through its own rigid structure, can maintain the semi-circular shape at the bottom after the drip irrigation bag is filled with water, preventing the bag from shifting due to the expansion of the bag body caused by the increase of water volume, thereby extending the service life of the device.

[0024] Please see Figure 1-4Multiple sets of claws 21 and sleeves 22 are provided on the hoop 2, so that the length of the hoop 2 can be adjusted according to the size of different tree trunks, thereby improving the versatility of the hoop 2. The thickness of the claws 21 is greater than the thickness of the sleeves 22, and the outer diameter of the end of the claws 21 is greater than the inner diameter of the sleeves 22, so that the claws 21 are locked after being put into the sleeves 22, preventing the claws 21 from falling off when the hoop 2 is subjected to the pulling force of the drip irrigation bag 1.

[0025] Please see Figure 1-4 The locking mechanism includes a first threaded section 321 and a second threaded section 322. The first threaded section 321 is adjacent to the sharp part of the ground nail 32, and the second threaded section 322 is located at the top of the ground nail 32. The bottom of the inner wall of the outer sleeve 3 has a fixing interface 301 corresponding to the first threaded section 321 and the second threaded section 322. The first threaded section 321 and the second threaded section 322 are connected and locked to the fixing interface 301. When the ground nail 32 is retracted and stretched, it can maintain stability and can complete the extension and retraction of the telescopic rod without any tools. This meets the needs of quick installation and storage in garden scenes and greatly reduces the operation threshold. The outer sleeve 3 and the ground nail 32 cooperate with each other. When the telescopic rod is in the extended state, the second threaded section 322 and the fixing interface 301 are threadedly locked. When the telescopic rod is in the retracted state, the first threaded section 321 and the fixing interface 301 are threadedly locked.

[0026] The working principle of this utility model is as follows: When the user uses this device to drip irrigate green trees, the telescopic rod needs to be stretched first. When the ground nail 32 is in the retracted state, the first thread section 321 of the ground nail 32 is in the threaded connection state with the fixing interface 301 of the outer tube 3. At this time, the ground nail 32 only needs to be rotated manually to loosen and pull out the ground nail 32. Then, the second thread section 322 of the ground nail 32 is threadedly connected with the fixing interface 301 of the outer tube 3. After tightening it, the telescopic rod stretching operation is completed. Then, the top back of the drip irrigation bag 1 is attached to the tree trunk surface to ensure the position of the drip irrigation bag 1. Then, by applying pressure to the top of the pressure block 31, the ground nail 32 is inserted into the soil to fix the drip irrigation bag 1. Next, use the hoop 2 to wrap around the tree trunk. Adjust the hoop 2 to a length that matches the thickness of the tree trunk. Put the claw 21 into the sleeve 22. When there is no pressure, the outer diameter of the claw 21 is larger than the inner diameter of the sleeve 22. This way, after the claw 21 is put into the sleeve 22, the tip of the claw 21 protrudes from the opening of the sleeve 22, thus achieving the effect of locking and fixing. At this time, the hoop 2 and the drip bag 1 form a circle that matches the tree trunk. The side of the hoop 2 that is in contact with the tree trunk is a rubber surface, so as to avoid the pulling force generated by the drip bag 1 after water is injected and cause strangulation to the surface of the tree trunk. At this point, the fixing of the drip irrigation tape 1 is complete, and water filling of the drip irrigation bag 1 can begin. The water inlet 11 adopts an elastic design and is in a closed state under normal conditions. When filling water, simply pinch the water inlet 11 gently from both sides with your hands. The elastic material deforms under force, causing the water inlet 11 to open and form a water inlet channel. Insert the water pipe into the water inlet 11 to start filling water. After the water filling is completed, remove the water pipe. The elastic material will automatically reset after losing its expansion resistance, causing the water inlet 11 to close again. The shaping ring 13 can keep the bottom of the drip irrigation bag 1, which is full of water, semi-circular, preventing the drip irrigation bag 1 from deforming significantly due to the large amount of water. Finally, the flow rate is adjusted by the regulating pipe 12, thereby more effectively drip irrigating the trees.
