Description

Technical Field

[0001] This utility model relates to the field of greening sprinkler devices, and in particular to a municipal greening sprinkler device with automatic angle adjustment. Background Technology

[0002] In municipal greening maintenance, traditional sprinkler systems, due to their fixed angles, are difficult to adapt to complex greening scenarios, easily leading to uneven irrigation and water waste. With the advancement of smart city and green city construction, there is an urgent need for refined and intelligent greening irrigation. To solve the shortcomings of traditional devices and achieve precise irrigation, water-saving efficiency, and intelligent management, municipal greening sprinkler systems with automatic angle adjustment have emerged, adapting to diverse greening scenarios and improving irrigation quality and efficiency.

[0003] Chinese patent document CN220654286U describes a garden greening sprinkler device, relating to the field of green plant irrigation. This device includes a water pipe, a water pump, and multiple vertical pipes. Each vertical pipe has an installation pipe and atomizing nozzles at its top. An installation ring is fixedly connected to the top of the inner cavity of each vertical pipe, and a blocking plate is installed inside the installation ring. A transmission rod and a force-bearing plate are installed on the top of the blocking plate. In this garden greening sprinkler device, water inside the vertical pipes is atomized by the atomizing nozzles and sprayed out to irrigate the green plants around the vertical pipes. This avoids the physical effort required for manual watering and reduces uneven watering. Furthermore, the atomized water sprayed from the nozzles reaches the outside of the green plants, preventing the situation where large amounts of water are applied without the plants' leaves receiving sufficient moisture during manual watering, thus achieving a rinsing effect on the green plants.

[0004] The aforementioned patent documents still have the following defects in practice:

[0005] In actual use, the atomizing nozzles are fixed by the threaded connection between the installation pipe and the vertical pipe. After long-term use, the vertical pipe is prone to water leakage, resulting in water waste. Moreover, when multiple vertical pipes supply water at the same time, it is difficult to start and stop the spray and control the water volume of a single vertical pipe, which makes it less flexible in adapting to the differentiated spraying needs of different green plants.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 and Figure 2As shown, an automatic angle-adjustable municipal greening sprinkler device includes an outer sleeve 1, an upper sleeve assembly 2 at the top of the outer sleeve 1, a sprinkler assembly 3 at the top of the upper sleeve assembly 2, a feed inlet 4 fixedly connected to the front end of the outer sleeve 1, a support frame 5 in the middle of the outer surface of the outer sleeve 1, a water inlet 6 at the bottom of the outer sleeve 1 for connecting a water supply pipe, and an inner sleeve assembly 7 in the inner cavity of the outer sleeve 1.

[0027] During implementation, a water storage tank is required, along with several water pipes connected to an external water pump. The water pump model is QDX3-24-0.75, which can inject clean water into the inner cavity of the inner sleeve assembly 7. In this implementation case, all connecting parts in the device are equipped with sealing rings, and all rotating structures in the device that need to be submerged in water are made of polytetrafluoroethylene (PTFE).

[0028] Preparation:

[0029] First, a water storage tank is prepared before implementation to hold clean water; then, a water pipe is installed at the input end of the water pump and the other end is placed in the water storage tank, and the output end of the water pump is connected to one end of the water inlet 6 in this example; finally, the device is preliminarily inspected and placed at the location where irrigation and spraying are required.

[0030] In this implementation case, the power is first turned on and the water pump is started. The water flows through the inlet 6 into the inner sleeve assembly 7 and is then transported upward to the upper sleeve assembly 2. The water then enters the spray assembly 3 through the upper sleeve assembly 2 and is sprayed out. During the spraying process, the internal structures of the device can cooperate with each other and automatically adjust the angle with the help of the water flow. At the same time, the support frame 5 outside the outer sleeve 1 ensures the stability of the device. Fertilizer or pesticides can be added at the feed inlet 4 as needed.

[0031] Specifically, in order to enhance the stability of the connection between the outer sleeve 1 and the support frame 5, such as Figure 1 As shown, the outer surface of the outer sleeve 1 has a ring array of several protrusions that are fixedly connected to the outer sleeve 1.

[0032] In this implementation case, during the spraying operation, the protrusions allow the outer sleeve 1 to be securely mounted on the support frame 5. The contact area of ​​its outer surface and the structural limit ensure a firm connection between the support frame 5 and the outer sleeve 1, preventing the support frame 5 from detaching from the outer sleeve 1 and ensuring the overall stability of the device.

[0033] Specifically, in order to achieve the goal of uniformly spraying green areas from multiple angles, such as Figure 2 As shown, the spray assembly 3 includes a water outlet pipe 31, and the middle and upper parts of the water outlet pipe 31 have a number of evenly distributed water outlet holes 32 in a ring array.

[0034] In this implementation case, after the water flows into the outlet pipe 31, it is sprayed outward from different directions with the help of the evenly distributed outlet holes 32 in a ring array, covering a wide green area around the outer sleeve 1.

[0035] Specifically, in order to achieve the purpose of filtering impurities from the spray water source, such as Figure 3 As shown, the inner sleeve assembly 7 includes a second sleeve 72, a plurality of water inlet holes 71 are provided on the lower part of the outer surface of the second sleeve 72, a filter screen 73 is provided on the top of the second sleeve 72, the top of the filter screen 73 is in contact with the top of the inner cavity of the outer sleeve 1, and a plurality of third water outlet holes 75 are provided on the upper part of the outer surface of the second sleeve 72.

[0036] In this implementation case, after the water source enters from the inlet 6, it flows into the inner cavity of the inner sleeve assembly 7 through the water inlet 71 at the bottom of the cylinder 2 72. When the water flows upward, it passes through the filter screen 73. The mud, sand and other impurities carried in the water are intercepted by the filter screen, ensuring that the spray water is clean, avoiding impurities from clogging the spray assembly 3, and improving the stability of the device.

[0037] During this process, when fertilizer or pesticides need to be added to the feed inlet 4, clean water enters the gap between the outer sleeve 1 and the inner sleeve assembly 7 through several water outlet holes 3 75 on the upper part of the cylinder 2 72, mixes and dissolves the fertilizer or pesticides, rises and diffuses with the rising water flow, and then flows into the mainstream through several water outlet holes 3 75.

[0038] Example 2: Based on Example 1, this example can achieve automatic adjustment of the spray angle;

[0039] Specifically, in order to achieve the above objectives, such as Figure 3 As shown, in this embodiment, the upper sleeve assembly 2 includes a cylinder body 21. A gear 22 is provided in the lower part of the inner cavity of the cylinder body 21. A reduction wheel 25 is provided in the middle of the inner cavity of the cylinder body 21. The lower outer side of the reduction wheel 25 meshes with the upper outer side of the gear 22. A cylinder cover assembly 24 is provided at the upper end of the cylinder body 21. Water pressure valves 23 are provided on both the left and right sides of the upper part of the inner cavity of the cylinder body 21. The bottom end of the cylinder cover assembly 24 is fixedly connected to the top ends of the two water pressure valves 23. A gear 26 is provided in the middle of the bottom end of the cylinder cover assembly 24. The outer side of the gear 26 meshes with the upper outer side of the reduction wheel 25.

[0040] In this implementation case, as the water pressure gradually increases, the cylinder cover assembly 24 moves due to the impact of the water flow, which drives the gear 26 at the bottom of the cylinder cover assembly 24 to rotate. Since the gear 26 meshes with the reduction wheel 25, and the lower part of the reduction wheel 25 meshes with the gear 22, the change in water pressure is converted into mechanical energy to rotate through transmission, thereby driving the outer shell of the cylinder 21 of the upper sleeve assembly 2 and the spray assembly 3 to rotate.

[0041] When the water flow velocity increases, the resulting water pressure rises, exerting pressure on the water pressure valve 23, allowing the water to flow through.

[0042] Specifically, in order to achieve stable water pressure transmission, such as Figure 5 As shown, the water pressure valve 23 includes a valve body 231, a spring 232 is provided in the inner cavity of the valve body 231, a rubber plate 233 is fixedly connected to the bottom end of the spring 232, and a water inlet is provided at the upper end of the valve body 231.

[0043] In this implementation case, the spring 232 provides elastic support for the rubber plate 233. When the water pressure is low, the spring 232 can reduce the impact of the water flow and reduce the displacement of the rubber plate 233, thus avoiding damage to the device due to instantaneous changes in water pressure. When the water pressure changes to a certain extent, the water pressure on the rubber plate 233 overcomes the elastic force of the spring 232 and causes it to continuously move upward. A large amount of water can flow upward through the two valve bodies 231 to reduce the pressure in the inner cavity of the upper sleeve assembly 2.

[0044] Specifically, in order to achieve the purpose of adjusting the spray direction by guiding the water flow, such as Figure 4 As shown, the cylinder cover assembly 24 includes a cylinder cover 241. Two water outlet holes 242 are opened on the left side of the top of the cylinder cover 241. Several baffles 243 are fixedly connected to the top of the cylinder cover 241 to guide the direction of water flow. A flywheel 244 is provided at the top of the cylinder cover 241.

[0045] In this implementation case, water is sprayed out from the outlet hole 242. Part of the water is guided by the baffle 243 on the cover 241, which drives the flywheel 244 to rotate at the top of the upper sleeve cover assembly 2, converting water pressure into mechanical energy. The flywheel 244 drives the gear 26 to rotate.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
