Abstract
Description
Technical Field
[0001] This application relates to the technical field of dry spraying, and in particular to a dry spray nozzle for landscape engineering. Background Technology
[0002] Dry fountains, also known as dry-ground fountains, refer to fountain facilities placed underground, with nozzles and lights concealed beneath a cover. When water is sprayed, the water jets emerge through holes in the cover or granite paving, achieving the effect of viewing the fountain without taking up leisure space. The pool, nozzles, and lights are all hidden beneath the cover, with water jets exiting through holes between the cover plates. When not spraying water, the surface is clean and open.
[0003] Dry fountains are often installed in parks or squares to enhance the city's image. Since dry fountains are usually installed underground, no protective structures are installed around them to reduce the impact on the use of the square when the fountain is not in use.
[0004] During the operation of the dry fountain, since there are no protective measures around the fountain, pedestrians can easily get their clothes wet when they walk to the fountain to wash their hands or play in the water, especially in the hot summer. Summary of the Invention
[0005] To mitigate the risk of pedestrians getting their clothes wet when approaching a dry fountain, this application provides a dry fountain nozzle for landscape engineering.
[0006] This application provides a dry sprinkler head for landscape engineering, employing the following technical solution: A dry sprinkler head for landscape engineering includes a lifting brick and a sprinkler head. A transmission mechanism is provided between the sprinkler head and the lifting brick to adjust the lifting and lowering of the sprinkler head and the direction of water spraying by adjusting the lifting and lowering of the lifting brick. The nozzle includes an upper nozzle and a side nozzle, and the nozzle is provided with a sealing mechanism for blocking the upper nozzle or the side nozzle.
[0007] By adopting the above technical solution, the dry fountain sprays water through the upper nozzle during daily use. The lifting bricks are set around the perimeter of the dry fountain. When pedestrians play near the dry fountain, if they walk to the lifting bricks near the fountain, the lifting bricks will descend under the pressure of the pedestrians, driving the transmission mechanism to operate. The transmission mechanism drives the fountain to rise and spray water through the side nozzles. At this time, the sealing mechanism blocks the upper nozzle and sprays water away from the pedestrians through the side nozzles, so that the dry fountain is less likely to splash water on the pedestrians' clothes.
[0008] Optionally, the nozzle includes an outer sleeve that can rise above the ground, the outer sleeve being vertically arranged, and a water supply hose being detachably connected to the bottom of the outer sleeve.
[0009] By adopting the above technical solution, water is supplied to the outer casing through a water supply hose, thereby enabling the sprinklers to spray water. Since the sprinklers can rise above the ground, when water is sprayed upwards through the upper sprinkler, the sprinklers are below the ground, reducing the impact of the sprinklers on the use of the square. When pedestrians step on the rising bricks, the sprinklers rise above the ground and spray water through the side sprinklers, making it convenient for pedestrians to play in the water or wash their hands.
[0010] Optionally, a transmission rod is fixed to the bottom of the lifting brick; The transmission mechanism includes a balance bar, with one end of the transmission rod away from the lifting brick hinged to one end of the balance bar, and the other end of the balance bar away from the transmission rod hinged to the side wall of the outer sleeve. The transmission rod is rotatably supported at its middle section.
[0011] By adopting the above technical solution, when the lifting brick descends, it drives the transmission rod to move downward, thereby pressing down one end of the balance bar. Under the support of the support seat, the balance bar, through the principle of leverage, causes the end of the balance bar connected to the outer sleeve to rise, thereby driving the outer sleeve part to rise above the ground.
[0012] Optionally, it also includes a vertically arranged sliding guide rail, which is fixed to the ground, and a slider that slides along the sliding guide rail is fixed on the side wall of the outer sleeve.
[0013] By adopting the above technical solution, when the outer tube slides up and down, the slider slides in the sliding guide rail to limit its movement path, so that the outer tube can slide vertically and reduce the occurrence of deviation during the movement of the outer tube.
[0014] Optionally, the outer sleeve has a first side hole and a second side hole, the side nozzle communicates with the second side hole, and a connecting pipe is provided between the side wall of the side nozzle and the first side hole. The sealing mechanism can be used to seal the connecting pipe or the outer sleeve.
[0015] By adopting the above technical solution, when the sealing mechanism blocks the connecting pipe, the water discharged from the water supply hose into the nozzle can flow along the outer sleeve to the upper nozzle and spray out; when the sealing mechanism blocks the outer sleeve, the water discharged from the water supply hose into the nozzle can flow along the connecting pipe to the side nozzle and spray out, thereby realizing the adjustment of the nozzle spray direction.
[0016] Optionally, the sealing mechanism includes a cap and a sealing ball. The cap is detachably connected to the outer tube. An elastic element is provided between the cap and the sealing ball. The sealing ball is provided with a driving element for driving the sealing ball to move in the direction of compressing the elastic element. Under the drive of the driving element, the sealing ball can seal the connecting pipe or the outer tube.
[0017] By adopting the above technical solution, the sealing ball, in its natural state, blocks the connecting pipe and the side nozzle. At this time, water can only flow into the upper nozzle from the outer sleeve and spray out through the upper nozzle. Under the drive of the driving component, the elastic component is compressed, causing the sealing ball to move to the outer sleeve and close the outer sleeve. At this time, the connecting pipe and the side nozzle are connected to the water supply hose, and water is sprayed out from the side nozzle.
[0018] Optionally, an installation side tube is provided on the side of the outer sleeve near the lifting brick, and the cap is threadedly connected to the end of the installation side tube away from the outer sleeve.
[0019] By adopting the above technical solution, an installation side pipe is set on one side of the outer sleeve, which facilitates the installation of the sealing mechanism and makes the installation, disassembly, maintenance and replacement of the sealing mechanism more convenient.
[0020] Optionally, the drive component includes a pull rope, one end of which is fixedly connected to the blocking ball, and the other end of which is fixedly connected to the end of the balance bar near the lifting brick.
[0021] By adopting the above technical solution, when a pedestrian stands on the rising brick, the rising brick moves downward, thereby causing one end of the balance bar to move downward. At this time, one end of the pull rope moves downward with the balance bar, and the pull rope pulls the sealing ball, so that the sealing ball can move from the connecting pipe opening to the outer sleeve, sealing the outer sleeve and opening the side nozzle. Thus, the function of closing the upper nozzle and opening the side nozzle is realized when a pedestrian stands on the rising brick. When the pedestrian leaves the rising brick, the sealing ball can return to its original position under the elastic restoring force of the elastic element, thereby realizing the sealing of the side nozzle and the opening of the upper nozzle.
[0022] Optionally, the side nozzle is located on the side of the outer casing away from the rising brick.
[0023] By adopting the above technical solution, the side nozzles are set on the side of the outer sleeve away from the rising brick, so that after the nozzles rise above the ground, the water flow is sprayed in a direction away from the rising brick, reducing the possibility of water splashing onto pedestrians' clothes.
[0024] Optionally, lifting springs are fixed at the four corners of the lifting brick.
[0025] By adopting the above technical solution, when pedestrians stand on the rising bricks, the rising bricks are not prone to sudden descent under the support of multiple rising springs, which would cause a poor experience for pedestrians; and when pedestrians leave the rising bricks, the rising bricks can return to their original position under the elastic restoring force of the rising springs.
[0026] In summary, this application includes at least one of the following beneficial effects: 1. When pedestrians stand on the rising bricks around the dry fountain, the nozzles can automatically rise and spray water from the side nozzles. This makes it convenient for pedestrians to play in the water or wash their hands, and also reduces the possibility of the water sprayed from the nozzles getting their clothes wet. 2. This application provides a transmission mechanism and a blocking mechanism, and both the transmission mechanism and the blocking mechanism are driven to move by the lifting of the lifting bricks, which makes the structure simple and can be driven by the lifting bricks at the same time. 3. Install side pipes to facilitate the replacement of the sealing mechanism and make it easy for staff to maintain and replace it. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a dry sprinkler head for landscape engineering, referring to... Figure 1 Multiple fountain nozzles are installed beneath the plaza floor. A type of dry fountain head for landscaping includes nozzles 2 located on the outermost ring of the fountain. Lifting bricks 1 are installed outside the nozzles 2. Under normal conditions, the lifting bricks 1 are at the same height as the rest of the plaza floor. When a pedestrian approaches the fountain and stands on the lifting bricks 1, the lifting bricks 1 can descend and drive the nozzles 2 to rise, thus changing the direction of the water spray.
[0031] Reference Figure 2The nozzle 2 includes an outer sleeve 23, which is vertically arranged. A water supply hose 5 is connected to the lower end of the outer sleeve 23, and the hose is connected to a water source, allowing water to flow into the outer sleeve 23. The nozzle 2 also includes an upper nozzle 21 located at the upper end of the outer sleeve 23 and side nozzles 22 located on the side wall of the outer sleeve 23. Under normal conditions, water in the nozzle 2 sprays upwards from the upper nozzle 21; when the nozzle 2 rises above the plaza floor, water in the nozzle 2 sprays out from the side nozzles 22. The side nozzles 22 are located on the side of the nozzle 2 furthest from the rising brick 1, making it less likely for water sprayed from the side nozzles 22 to splash onto pedestrians.
[0032] Reference Figure 2 Multiple lifting springs 12 are installed below the lifting brick 1, preferably four lifting springs 12, and the four lifting springs 12 are respectively installed near the four corners of the lifting brick 1. When a pedestrian stands on the lifting brick 1, the lifting brick 1 slowly descends; when the pedestrian leaves the lifting brick 1, the lifting brick 1 returns to its original position under the elastic restoring force of the lifting springs 12.
[0033] Reference Figure 2 and Figure 3 A transmission mechanism 3 is provided between the lifting brick 1 and the nozzle 2. A sealing mechanism 4 is provided inside the nozzle 2. The sealing mechanism 4 is used to seal the side nozzle 22 or the upper nozzle 21. The lifting of the lifting brick 1 can be transmitted to the sealing mechanism 4 through the transmission mechanism 3 and drive the sealing mechanism 4 to operate.
[0034] Reference Figure 2 Specifically, the transmission mechanism 3 includes a transmission rod 11 fixed to the bottom of the lifting brick 1. The transmission rod 11 is vertically arranged, and a balance rod 31 is hinged to the end of the transmission rod 11 away from the lifting brick 1. A support seat 32 is rotatably arranged in the middle of the balance rod 31, and the end of the balance rod 31 away from the transmission rod 11 is hinged to the side wall of the outer sleeve 23. According to the lever principle, when the lifting brick 1 moves downward, the end of the balance rod 31 near the lifting brick 1 descends, and the end of the balance rod 31 near the outer sleeve 23 rises, thereby causing the outer sleeve 23 to partially rise above the floor surface.
[0035] Reference Figure 2 A slider is fixed to the side wall of the outer tube 23, and a sliding guide rail 6 is fixed to the bottom of the floor around the lifting brick 1. The sliding guide rail 6 is vertically set, and the slider is inserted into and slides within the sliding guide rail 6. The grooves opened in the slider and the sliding guide rail 6 can be mating wedges and dovetail grooves; the slider is not shown in the figure. The slider and the sliding guide rail 6 enable the outer tube 23 to rise and fall vertically, preventing it from deviating from its direction.
[0036] Reference Figure 3The outer sleeve 23 has a first side hole 231 and a second side hole 232 respectively on its side wall. The first side hole 231 is located below the second side hole 232. The side nozzle 22 is connected to the second side hole 232. A connecting pipe 7 is provided at the first side hole 231. The end of the connecting pipe 7 away from the first side hole 231 is connected to the side wall of the side nozzle 22.
[0037] Reference Figure 3 The sealing mechanism 4 includes a sealing ball 42 capable of sealing the outer sleeve 23 or sealing the connection port between the connecting pipe 7 and the side nozzle 22. An elastic element 43 is fixed to one end of the sealing ball 42 away from the side nozzle 22. The elastic element 43 can be a spring. A cap 41 is fixed to one end of the elastic element 43 away from the sealing ball 42. The cap 41 is threadedly connected to the outer sleeve 23.
[0038] Reference Figure 2 and Figure 3 The outer sleeve 23 has a mounting side tube 8 on the side opposite to the side nozzle 22, and the cover 41 is threaded to the end of the mounting side tube 8. The sealing ball 42 is provided with a driving component for driving the sealing ball 42 to move in the direction of the compression elastic member 43. The driving component is a pull rope 44 fixed on the sealing ball 42, and the end of the pull rope 44 away from the sealing ball 42 is fixedly connected to the end of the balance bar 31 near the lifting brick 1. The cover 41 has a hole for the pull rope 44 to pass through, and the diameter of the pull rope 44 and the hole are matched, so that water is difficult to leak out from the gap between the pull rope 44 and the side wall of the hole.
[0039] Reference Figure 2 and Figure 3 In its natural state, the elastic element 43 has the sealing ball 42 located at one end of the connecting pipe 7 and sealing the end of the connecting pipe 7. When a pedestrian stands on the lifting brick 1, the lifting brick 1 descends, the outer sleeve 23 rises, and the end of the balance bar 31 near the lifting brick 1 also descends, causing the pull rope 44 to move down the end near the lifting brick 1. The other end of the pull rope 44 pulls the sealing ball 42 to move in the direction of compressing the elastic element 43, so that the sealing ball 42 can seal the outer sleeve 23. At this time, the side nozzle 22 is connected to the water supply hose 5, the upper nozzle 21 is closed, and water is sprayed out from the side nozzle 22.
[0040] The implementation principle of a dry fountain nozzle for landscape engineering in this application embodiment is as follows: When the fountain is in daily use, the nozzle 2 is located below the plaza floor, and the sealing ball 42 is located at the end of the connecting pipe 7, sealing the connecting pipe 7 and the side nozzle 22, so that the water in the water supply hose 5 can only be sprayed out from the upper nozzle 21, and then sprayed onto the plaza floor to form a fountain landscape.
[0041] When pedestrians want to use the fountain water to wash their hands or play in the water, they will step on the rising bricks 1 around the fountain when they walk to the fountain. The rising bricks 1 will descend under the action of the pedestrian's gravity, which will cause one end of the balance bar 31 to descend. At this time, the other end of the balance bar 31 will rise under the action of the lever principle, thereby causing the outer sleeve 23 to rise to the ground along the sliding guide rail 6.
[0042] As the balance bar 31 descends near the lifting brick 1, it causes the pull rope 44 to move downwards. The pull rope 44 pulls the sealing ball 42 to move along the direction of the compression elastic element 43. When a pedestrian stands on the lifting brick 1, the sealing ball 42 can move into the outer sleeve 23 under the pulling force of the pull rope 44 and seal the outer sleeve 23. At this time, the water in the water supply hose 5 enters the side nozzle 22 from the connecting pipe 7 and sprays out from the side nozzle 22. Since the side nozzle 22 is located on the side of the outer sleeve 23 away from the lifting brick 1, the water sprayed from the side nozzle 22 is less likely to splash onto the pedestrian and is easy for the pedestrian to absorb and play with.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
