DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] Please see Figures 1-7 The present invention provides a technical solution: a garden irrigation and spraying device for municipal engineering, including a water tank 14, a water guide pipe 10 rotatably connected to the top of the water tank 14, a guide plate 11 fixedly connected through one side of the water guide pipe 10, and a water supply pipe 17 fixedly connected through one side of the water tank 14. A fixed shell 1 is provided on one side of the guide plate 11. A pouring port is opened on one side of the fixed shell 1. An upper telescopic cylinder 18 and a lower telescopic cylinder 20 are fixedly connected to the top and bottom of the fixed shell 1, respectively. A lower stop block 3 is fixedly connected to the top of the telescopic end of the lower telescopic cylinder 20. An atomizing plate 19 is fixedly connected to the bottom of the telescopic end of the upper telescopic cylinder 18. A water spray hole is opened on the side of the atomizing plate 19. An upper stop block 2 is fixedly connected to the bottom of the atomizing plate 19. Both the upper stop block 2 and the lower stop block 3 are set in a right-angled triangular block style. The upper stop block 2 is set inclined downward and the lower stop block 3 is set inclined upward. A diversion component for recycling water flow is provided on one side of the fixed shell 1.

[0020] Furthermore, the diversion assembly includes a recovery block 4 and a guide pipe 5. The top of the guide pipe 5 is fixedly connected to the bottom of the recovery block 4. A baffle 9 is fixedly connected to one side of the recovery block 4. The recovery block 4 is fixedly connected to the fixed shell 1 through the baffle 9. A recovery port is opened on one side of the recovery block 4. The bottom end of the guide pipe 5 is rotatably connected to a return box 8. The bottom of the water injection tank 14 is fixedly connected to the bottom of the inner wall of the return box 8. The end of the water supply pipe 17 away from the water injection tank 14 is fixedly connected to one side of the return box 8. A return pipe 7 is fixedly connected to one side of the return box 8. The water flow in the space formed by the inclined surface of the upper baffle 2 or the lower baffle 3 and the vertical surface of the recovery block 4 can be guided and recovered. This can ensure the stability of the main water flow and also allow drip irrigation to be performed in the external drip irrigation equipment near the recovered water flow guiding device.

[0021] Furthermore, a motor 16 and a protective shell 6 are fixedly connected to the top of the return box 8. The motor 16 is fixedly installed inside one end of the protective shell 6. A main wheel 15 is fixedly connected to the top of the motor 16. A driven wheel 12 is fixedly connected through the bottom end of the guide pipe 5. The main wheel 15 and the driven wheel 12 are meshed and engaged with each other, which can drive the device to perform a rotating spraying operation. A rotating groove is opened at the top of the protective shell 6. The main wheel 15 and the motor 16 are rotatably connected in the rotating groove. The bottom end of the guide pipe 5 is rotatably connected through the end of the protective shell 6 away from the motor 16.

[0022] Furthermore, an arc-shaped baffle 25 is fixedly connected to the inner wall of the recovery block 4 near the recovery port. The arc-shaped baffle 25 consists of an arc-shaped plate and a straight plate. A pressure relief port is formed through the straight plate end of the arc-shaped baffle 25, which avoids all leaked water flow being forcibly guided back to the main jet flow, causing severe turbulence and pressure loss. The main water flow will be less disturbed and more stable.

[0023] Furthermore, a sealing ring 13 is fixedly connected to the side of the bottom end of the guide pipe 5. The top of the sealing ring 13 rotates and fits against the top of the inner wall of the return box 8. A sealing ring 22 is fixedly connected to the side of the bottom end of the water guide pipe 10, which can increase the sealing performance of water flow introduction and export. The top of the sealing ring 22 rotates and fits against the top of the inner wall of the water injection tank 14.

[0024] Furthermore, sealing plates 21 are fixedly connected to the bottom of the upper baffle 2 and the top of the lower baffle 3 to improve the sealing effect of the fixed shell 1 when it is not in use and prevent debris from entering the device through the pouring port on one side of the fixed shell 1. Sealing plate 23 is fixedly connected to the end of the guide plate 11 away from the water pipe 10 to improve the sealing performance of the guide plate 11 when guiding water.

[0025] Furthermore, a sealing frame plate 24 is fixedly connected to the inner wall of the fixed shell 1. The telescopic ends of the upper telescopic cylinder 18 and the lower telescopic cylinder 20 are respectively slidably connected to the top and bottom of the sealing frame plate 24, which further enhances the sealing effect of the inner wall of the fixed shell 1 when the pouring port on one side of the fixed shell 1 is dynamically adjusted.

[0026] Furthermore, the atomizing plate 19 is U-shaped, and the upper and lower sides of one end of the atomizing plate 19 are movably attached to the upper and lower sides of the sealing plate 23, which allows for atomization spraying operations without allowing water to enter the interior of the fixed shell 1.

[0027] First, connect the water supply pipe 17 to the external water supply equipment and the return pipe 7 to the external drip irrigation equipment. This is mainly used to replenish water in areas that are close to the device but cannot be sprayed properly. When watering and spraying in the fixed shell 1, if the plants in the area have similar habits and require roughly the same amount of water, the upper telescopic cylinder 18 can be activated to move the atomizing plate 19 downwards, and the lower telescopic cylinder 20 can move the lower stop block 3 downwards, so that one side of the atomizing plate 19 is in contact with the sealing plate 23 on one side of the guide plate 11. Thus, the water flows through the water supply pipe 17-water tank 14-water guide pipe 10-guide plate 11 and sprays through the atomizing plate 19. By activating the motor 16 at the bottom of the guide pipe 5, the motor 16 can drive the guide pipe 5, the recovery block 4, the water guide pipe 10, the guide plate 11 and the fixed shell 1 to rotate and spray. When segmented irrigation and spraying operations are required, such as when irrigation operations need to be carried out at a greater distance, the upper telescopic cylinder 18 and the lower telescopic cylinder 20 can be activated simultaneously to make the upper block 2 and the lower block 3 gradually move closer together, thereby adjusting the width of the irrigation port on one side of the fixed shell 1. The closer the distance between the upper block 2 and the lower block 3, the narrower the water outlet channel of the irrigation port. The narrow channel reduces the cross-sectional area of ​​the water flow, converts water pressure energy into kinetic energy, and makes the water flow ejected at a higher speed, with a stronger ability to overcome air resistance, thus spraying further. However, the water outlet channel formed by the upper block 2 and the lower block 3 should not be too narrow, as this will lead to water turbulence and cavitation. Conversely, the farther the distance between the upper block 2 and the lower block 3, the wider the water outlet channel of the irrigation port, and the closer the irrigation distance is to the device. The farthest distance between the upper block 2 and the lower block 3 is equal to the distance of the irrigation port. In areas requiring comprehensive humidification, such as lawns, ground cover plants, and dense flower beds, and when localized air humidity needs to be increased, to enhance wind resistance and reduce drift loss, the upper telescopic cylinder 18 can move the upper baffle 2 upwards, and the lower telescopic cylinder 20 can move the lower baffle 3 upwards, positioning the lower baffle 3 at the irrigation inlet. The upward-sloping side of the lower baffle 3 allows water to spray upwards, with most of the water droplets rising and falling vertically in the air, making them less affected by horizontal wind forces. Even in windy conditions, the impact is mainly on the highest point of the droplet's fall, resulting in a more stable and controllable irrigation area. Conversely, when the upper baffle 2 is positioned at the irrigation inlet, the water flows downwards along the downward-sloping side of the upper baffle 2, allowing the water to directly reach the soil around the plant roots. This minimizes the time water droplets spend in the air, almost completely avoiding evaporation loss and the effects of wind. For example, when irrigating under shrubs, downward irrigation can directly deliver water to the roots, avoiding obstruction from the branches and leaves above. Since the contact surfaces of the upper baffle 2 and the lower baffle 3 with one side of the guide plate 11 are inclined, when the upper baffle 2 and the lower baffle 3 are not completely closed and the inclined surfaces are completely located at the pouring port, when the guide plate 11 is performing water conveyance, some of the water flow will move into the angle space formed by the inclined surface of the upper baffle 2 or the lower baffle 3 and the vertical surface of the recovery block 4. If the water flow is directly blocked, and the water flow is ejected directly after hitting the upper baffle 2 or the lower baffle 3, although the loss of water flow can be reduced, the impact of the water flow on the upper baffle 2 or the lower baffle 3 will generate large turbulence and vortices. This part of the energy will be converted into heat energy and internal energy and lost instead of being used to propel the water flow. This will lead to a decrease in the jetting efficiency (i.e., the water flow range under the same pressure) and is prone to water hammer and vibration, thereby reducing the structural life. Therefore, a diversion component was designed. Since the width of the recovery port on one side of the recovery block 4 is greater than that of the guide plate 11, when there is an angled space, the water flow will pass through the angled space. Part of the water flow will be sprayed out along the water flow, while the other part will enter the recovery block 4 through the space between the guide plate 11 and the recovery port. Since the recovery block 4 is equipped with an arc-shaped baffle 25, most of the water flow will still be blocked by one end of the arc-shaped baffle 25 and will flow back into the main jet flow. This ensures that the performance of the main jet (such as speed and flow rate) does not decrease by more than a certain acceptable threshold (e.g., 5%). At the same time, a pressure relief port is formed by the straight end of the arc-shaped baffle 25, which avoids all the leaked water flow being forcibly guided back to the main jet flow, causing severe turbulence and pressure loss. The main jet flow will be less disturbed and more stable. The recovered water flow is then guided to the external drip irrigation equipment through the following flow sequence: recovery block 4 - guide pipe 5 - return box 8 - return pipe 7, so as to carry out drip irrigation operation on nearby areas that cannot be irrigated by the device.
