Description

Technical Field

[0001] This utility model relates to the field of floor-mounted sprinkler technology, specifically a floor-mounted sprinkler. Background Technology

[0002] A ground sprinkler is an irrigation device that is mainly installed on the ground and sprays water out in a certain shape and range.

[0003] The spray range of existing ground sprinklers during irrigation largely depends on the water pressure supplied by the pump. The higher the water pressure, the larger the spray range. However, when water is drawn directly from the ground without a pump, the spray range is greatly reduced due to the lack of pump pressure. This necessitates adding more ground sprinklers to meet the site's irrigation needs, which significantly increases costs. Utility Model Content

[0004] In view of this, the present invention provides a ground-mounted sprinkler head, which aims to solve the problems of low water pressure and the need to add more sprinkler heads in the prior art.

[0012] A further improvement of this utility model is that the angle between the water guide plate and the horizontal plane is 21 degrees to 33 degrees.

[0013] A further improvement of this utility model is that the snap-fit ​​assembly includes:

[0014] A sleeve is coaxially arranged with the secondary tube. The inner wall of the first end of the sleeve is connected to the outer wall of the second end of the secondary tube. A cap is provided at the second end of the sleeve. The cap is located outside the second end of the secondary tube. A through hole is provided in the middle of the cap.

[0015] The first conical sleeve is horizontally disposed inside the secondary tube, with its smaller end connected to the circumferential surface of the through-hole, and its larger end in contact with the inner wall of the secondary tube.

[0016] The elastic claw is slidably disposed inside the first conical sleeve and cooperates with the first conical sleeve to clamp the water inlet pipe that enters the secondary pipe from the sleeve.

[0017] A further improvement of this utility model is that the elastic claw includes:

[0018] An annular baffle is coaxially arranged with the sleeve and located outside the second end of the cap;

[0019] Multiple clamping plates are provided, with their first ends connected to the inner circumferential surface of the annular baffle and evenly distributed along the circumferential direction of the annular baffle. A conical plate is provided on the outer surface of the second end of the clamping plate, with the larger end of the conical plate facing opposite directions to the larger end of the first conical sleeve.

[0020] A further improvement of this utility model is that an annular platform is provided inside the secondary tube, a sealing ring is provided between the first side of the annular platform and the elastic claw, and the second side of the annular platform is connected to the larger end of the tapered tube.

[0021] A further improvement of this utility model is that the top of the nozzle is provided with a plurality of water spray holes along its circumference.

[0022] A further improvement of this utility model is that the ground plug is conical, and the larger end of the ground plug is connected to the lower end of the main pipe.

[0025] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0026] This utility model provides a floor-mounted sprinkler head. The water inlet pipe is connected to the second end of a secondary pipe via a snap-fit ​​assembly, allowing water to enter the secondary pipe. Water then enters the conical pipe from its larger end and then from its smaller end into a pressurizing pipe. After passing through a guide plate, the water enters the sprinkler head from its upper end. The sprinkler head then sprays water. The conical pipe gradually reduces the inner diameter of the water flow, increasing the water flow velocity and pressure. Furthermore, the guide plate reduces pressure loss as the water flows, resulting in smoother flow and less pressure loss. Therefore, the sprinkler head has a longer spray radius. Compared to existing technologies, this design increases water pressure, reduces the need for floor-mounted sprinklers, and lowers costs. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0034] This utility model provides a floor-mounted sprinkler head, which, in conjunction with the instruction manual, is described below. Figure 1 To be continued Figure 3 It can be seen that a ground-mounted sprinkler head mainly includes the following parts or components: main pipe 10, secondary pipe 11, ground socket 40, tapered pipe 111, and pressurization pipe 101.

[0035] In this invention, a detachable nozzle 30 is provided at the upper end of the main pipe 10; the secondary pipe 11 is perpendicular to the main pipe 10, with its first end connected to the main pipe 10 and its second end provided with a snap-fit ​​assembly 20; the upper end of the floor plug 40 is connected to the lower end of the main pipe 10; a tapered pipe 111 is fixedly installed inside the secondary pipe 11 and coaxial with the secondary pipe 11, with the outer surface of the larger end of the tapered pipe 111 connected to the inner surface of the second end of the secondary pipe 11; and a pressurizing pipe 101 is fixedly installed inside the main pipe 10 and connected to the main pipe 10. 0. Coaxial, the upper end of the pressurizing pipe 101 is connected to the outlet (not shown in the figure) at the upper end of the main pipe 10, the lower end of the pressurizing pipe 101 is closed (not shown in the figure), the inlet (not shown in the figure) on one side of the lower end of the pressurizing pipe 101 is connected to the smaller end of the tapered pipe 111, and an inclined water guide plate 102 is fixedly installed inside the pressurizing pipe 101. The lower end of the water guide plate 102 is connected to the lower end of the inlet, and the higher end of the water guide plate 102 is connected to the inner wall of the pressurizing pipe 101 opposite to the inlet.

[0036] The water supply inlet pipe is connected to the second end of the secondary pipe 11 via the snap-fit ​​assembly 20, allowing water to enter the secondary pipe 11. Water then enters the conical pipe 111 from its larger end and the pressurization pipe 101 from its smaller end. The water in the pressurization pipe 101 passes through the guide plate 102 and then enters the nozzle 30 from its upper end. The nozzle 30 then sprays water. The conical pipe 111 gradually reduces the inner diameter of the water flow, increasing the water flow velocity and pressure. Furthermore, the guide plate 102 reduces water pressure loss as the water flows, resulting in smoother flow and less pressure loss. Therefore, the nozzle 30 has a longer spray radius and can increase water pressure, reducing the need for the ground-inserted nozzle 30 and lowering costs.

[0037] Specifically, the guide plate 102 can also be understood as having a chamfered edge at the lower end of the pressurizing pipe 101. When water passes through the pressurizing pipe 101, the right-angled edge of the un-chamfered pressurizing pipe 101 easily causes water flow separation. When water passes through the right-angled edge, a local low-pressure zone is formed, causing the water flow to detach from the pipe wall and generate vortices. However, after the pressurizing pipe 101 is chamfered, the water flow can smoothly enter along the chamfered slope, maintaining the continuity of the water flow. This continuous water flow helps to reduce the energy loss of the water flow.

[0038] Specifically, the cone angle of the conical tube 111 is 42 to 68 degrees. In practical use, modifying the cone tube 111 to 42 to 68 degrees will increase the diffusion range of the water flow, but will still maintain a certain range. This can increase the water spray coverage area by 1.5 to 2.5 times.

[0039] Specifically, the angle between the guide plate 102 and the horizontal plane is between 21 and 33 degrees. Within this angle range, the horizontal velocity component of the water flow allows for effective utilization of water pressure to a certain extent. Because of the high horizontal velocity, when the water flows over the guide plate 102, its kinetic energy is mainly used for horizontal propulsion, resulting in relatively low water pressure loss.

[0040] As one embodiment, in conjunction with the appendix to the specification Figure 3 As can be seen, the snap-fit ​​assembly 20 includes a sleeve 21, which is coaxially arranged with the secondary pipe 11. The inner wall of the first end of the sleeve 21 is connected to the outer wall of the second end of the secondary pipe 11. A cap 212 is fixedly provided at the second end of the sleeve 21. The cap 212 is located outside the second end of the secondary pipe 11. A through hole (not shown in the figure) is provided in the middle of the cap 212. The first conical sleeve 211 is horizontally arranged inside the secondary pipe 11. Its smaller end is connected to the circumferential surface of the through hole. The larger end of the first conical sleeve 211 is in contact with the inner wall of the secondary pipe 11. The elastic claw is slidably arranged inside the first conical sleeve 211 and cooperates with the first conical sleeve 211 to snap the water inlet pipe that enters the secondary pipe 11 from the sleeve 21.

[0041] The elastic claw (not shown in the figure) includes an annular baffle 221, which is coaxially arranged with the sleeve 21 and located outside the second end of the cap 212; the first ends of multiple clamping plates 222 are connected to the inner circumferential surface of the annular baffle 221 and are evenly distributed along the circumferential direction of the annular baffle 221; the outer surface of the second end of the clamping plate 222 is provided with a conical plate 225, the larger end of the conical plate 225 is opposite to the larger end of the first conical sleeve 211, and the outer surface of the larger end of the conical plate 225 is slidably connected to the inner wall of the larger end of the first conical sleeve 211.

[0042] The inlet pipe extends from the cap 212 and the elastic clamp into the secondary pipe 11. The elastic clamp clamps the inlet pipe, and then water is supplied. The end of the inlet pipe is pushed outward by the water source. Inside the sleeve 21, there is a first conical sleeve 211. The first conical sleeve 211 and the conical plate 225 at the second end of the clamping plate 222 face opposite directions. Therefore, when the inlet pipe moves outward, it will drive the clamping plate 222 and the conical plate 225 to move. As the first conical sleeve 211 moves outward, it becomes narrower. The larger ends of the multiple conical plates 225 move outward, and under the action of the first conical sleeve 211, they converge inward, thus clamping the inlet pipe more tightly. This can effectively reduce the risk of the inlet pipe detaching from the secondary pipe 11 and improve irrigation efficiency.

[0043] Specifically, a protrusion 223 is fixedly provided on the inner surface of the second end of the clamping plate 222, and both the clamping plate 222 and the protrusion 223 are arc-shaped. This allows for better clamping of the water inlet pipe. Furthermore, the outer surface of the clamping plate 222 can better fit the inner wall of the first conical sleeve 211, avoiding damage to the inner wall of the first conical sleeve 211 caused by sharp edges. The protrusion 223 can better contact the water inlet pipe, reducing damage to the water inlet pipe while clamping it.

[0044] Specifically, an annular platform (not shown in the figure) is fixedly installed inside the secondary pipe 11. A sealing ring 23 is fixedly installed between the first side of the annular platform and the elastic claw. The second side of the annular platform is connected to the larger end of the tapered pipe 111. This enhances the sealing effect and reduces the risk of water leakage.

[0045] As one embodiment, in conjunction with the appendix to the specification Figure 1 It can be seen that the top of the nozzle 30 has multiple water spray holes 31 arranged along its circumference. It can spray in multiple directions.

[0046] As one embodiment, in conjunction with the appendix to the specification Figure 1 As can be seen, the ground plug 40 is conical, with its larger end connected to the lower end of the main pipe 10. A reinforcing rib 41 is fixedly installed on the outside of the ground plug 40. The ground plug 40 can be quickly inserted into the area requiring irrigation, facilitating operation, and the reinforcing rib 41 makes the ground plug 40 more robust and durable.

[0047] This utility model provides a floor-mounted sprinkler head, and its specific operation process during use is as follows:

[0048] The water supply inlet pipe is connected to the second end of the secondary pipe 11 via the snap-fit ​​assembly 20, allowing water to enter the secondary pipe 11. Water then enters the conical pipe 111 from its larger end and the pressurization pipe 101 from its smaller end. The water in the pressurization pipe 101 passes through the guide plate 102 and then enters the nozzle 30 from its upper end. The nozzle 30 then sprays water. The conical pipe 111 gradually reduces the inner diameter of the water flow, increasing the water flow velocity and pressure. Furthermore, the guide plate 102 reduces water pressure loss as the water flows, resulting in smoother flow and less pressure loss. Therefore, the nozzle 30 has a longer spray radius and can increase water pressure, reducing the need for the ground-inserted nozzle 30 and lowering costs.
