Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to an adjustable-angle water conservancy nozzle bracket. Background Technology

[0002] A sprinkler head is a device typically used in irrigation or fire suppression systems. It sprays water to cover a specific area, and its main function is to distribute water evenly to the soil or a specific area to help plants grow, maintain humidity, or extinguish fires.

[0003] There are many types of existing irrigation sprinklers. For example, there is an irrigation sprinkler disclosed in patent CN209985616U. In this device, water enters the sprinkler cover from the inlet channel upwards. Due to the reverse obstruction effect at the top of the sprinkler cover, the water pressure increases dramatically and is sprayed outwards along the inclined spray rack. The downward-inclined spray rack continues the increased water pressure, and the actual sprayed water is in the form of particles, which increases the spray distance, has a wind-resistant effect, and ensures better uniformity of water spray. However, during the use of the irrigation sprinkler, a pipe connection is required. When the water flows in the pipe, it will rub against the inner wall of the pipe. If the pipe has an excessively large bend angle, the water pressure of the sprinkler will still decrease. Insufficient water pressure will reduce the spray distance of the sprinkler, resulting in ineffective irrigation of the designated area. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an adjustable angle hydraulic nozzle bracket, which can effectively solve the problem of reduced water pressure caused by the bending of the water conveying pipe in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an adjustable-angle hydraulic sprinkler head bracket, including:

[0007] disc;

[0008] An angle adjustment assembly includes a rotating disk rotatably mounted on the upper surface of a disc. A rotating joint is fixedly mounted on the upper surface of the rotating disk. The rotating joint consists of a fixed seat and a movable seat rotatably connected to each other. A locking head is fixedly mounted on the upper surface of the movable seat. A locking groove is formed in the locking head. Fixed blocks are symmetrically fixedly mounted on one side of the locking groove. A rotating column is rotatably mounted between the fixed blocks. Gears are circumferentially arrayed and fixedly mounted on the outer wall of the rotating column at positions corresponding to the locking groove. A speed detection element is provided on one side of one of the fixed blocks. The speed detection element is electrically connected to a controller. External brackets are fixedly mounted on both sides of the movable seat. An electromagnet is provided on the lower surface of one of the external brackets. The electromagnet is electrically connected to the controller.

[0009] Preferably, a plurality of fixed brackets are fixedly mounted on the lower end face of the disk in a circumferential array, and a rotary drive device is fixedly mounted on the lower end face of the disk. The output end of the rotary drive device passes through the disk and is fixedly connected to the rotating disk.

[0010] Preferably, a bolt is slidably installed inside the clamp head, a spring is fixedly installed between the external bracket and the rotating disk, an external frame is fixedly installed on one side of one of the fixing blocks, the inner wall of the external frame is fixedly connected to the speed detection element, and a short shaft is fixedly installed through the fixing block at one end of the rotating column.

[0011] Preferably, it also includes a recycling component, the recycling component including a first sleeve fixedly installed on the upper end face of the rotating disk, and a second sleeve fixedly installed on the upper end face of the disk.

[0012] Preferably, the outer wall of the first sleeve has a water outlet at a lower position, and the outer wall of the rotating disk has a swing rod fixedly installed at the position corresponding to the water outlet. The first sleeve and the second sleeve are fixedly installed with two isolation plates. The isolation plates, the first sleeve and the second sleeve form a water inlet space. A limit plate is fixedly installed on the side of the isolation plate close to the water inlet space, and a water storage cover is fixedly installed on the side of the isolation plate away from the water inlet space. A one-way valve is embedded in the inner wall of the isolation plate below the limit plate.

[0013] Preferably, the upper end face of the water storage cover is connected to a flow pipe, and a fixing plate is symmetrically installed on one side of the clamp head. The upper end of the flow pipe is fixedly connected to the inner wall of the fixing plate.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By linking the rotation speed detection element with the electromagnet, intelligent adjustment of the sprinkler head angle is achieved. When the water pressure decreases and the sprinkler head range shortens, the controller automatically increases the magnetic attraction of the electromagnet according to the change in the rotation speed of the rotating column, driving the external bracket to increase the swing angle of the clamp, so that the sprinkler head can provide compensatory irrigation with a wider coverage area. When the water pressure is sufficient, the swing angle is automatically reduced to prevent over-spraying. This design effectively solves the problem of uneven irrigation caused by water pressure fluctuations in traditional fixed-angle sprinklers, and can maintain stable coverage efficiency even in complex hydrological environments.

[0016] 2. The system utilizes a centrifugal water storage structure formed by the first and second sleeves through a recovery component. Combined with the mechanical movement of the swing arm, it performs three-stage recovery of leaked water generated during nozzle operation: First, the water is collected by the guide groove on the rotating disc and directed to the outlet. Then, it is centrifugally pressed into the water storage hood for storage. Finally, the recovered water is reintroduced into the spraying area through the flow pipe. The combination design of the one-way valve and the limit plate ensures unidirectional water flow and avoids high-pressure backflow from affecting normal spraying. This system achieves the recovery and reuse of more than 90% of leaked water without the need for additional power, making it particularly suitable for water-saving irrigation operations in arid regions.

A locking head 203 is fixedly mounted on the upper surface of the movable seat. A slot 204 is opened in the locking head 203. Fixed blocks 206 are symmetrically mounted on one side of the slot 204. Rotating columns 207 are rotatably mounted between the fixed blocks 206. Toothed plates 208 are fixedly mounted in a circumferential array on the outer wall of the rotating column 207 at the position corresponding to the slot 204.

The inner wall of the external bracket 209 is fixedly connected to the speed detection element 210. A short shaft is fixedly installed at one end of the rotating column 207 through the fixing block 206.

[0029] Reference Figures 2 to 4 It also includes a recycling component 3, which includes a first sleeve 301 fixedly installed on the upper end face of the rotating disk 201, a second sleeve 302 fixedly installed on the upper end face of the disk 1, an outlet 303 opened on the outer wall of the first sleeve 301 at a lower position, a swing rod 304 fixedly installed on the outer wall of the rotating disk 201 at the position corresponding to the outlet 303, and two isolation plates 305 fixedly installed on the first sleeve 301 and the second sleeve 302. 1. The second sleeve 302 forms a water inlet space. A limiting plate 306 is fixedly installed on the side of the isolation plate 305 near the water inlet space. A water storage cover 307 is fixedly installed on the side of the isolation plate 305 away from the water inlet space. A one-way valve 308 is embedded in the inner wall of the isolation plate 305 and below the limiting plate 306. A flow pipe 309 is connected to the upper end face of the water storage cover 307. A fixing plate 310 is symmetrically installed on one side of the clamp 203. The upper end of the flow pipe 309 is fixedly connected to the inner wall of the fixing plate 310.

[0030] The working principle of this utility model is as follows:

[0031] By installing the nozzle inside the slot 204 and the bolt 205 inside the clamp 203, the slot 204 clamps the nozzle. By activating the rotary drive to drive the rotating disk 201 to rotate reciprocally, the nozzle can swing left and right to irrigate the designated area. When the nozzle sprays water, some of the water flow contacts the toothed blade 208, causing it to drive the rotating column 207 and the short shaft to rotate. The speed detection element 210 detects the rotation speed of the short shaft. When the water pressure is high, the water flow is fast, and the rotation speed of the toothed blade 208 and the short shaft is also fast; when the water pressure is low, the water flow is slow, and the rotation speed of the toothed blade 208 and the short shaft is also slow. The speed detection element 210 generates a corresponding electrical signal based on the rotation speed of the short shaft. The controller controls the voltage input to the electromagnet 213 through the generated electrical signal, so that the electromagnet 213 can generate a corresponding magnetic force according to the water pressure, attracting the external bracket 211 to rotate at different amplitudes. The rotating external bracket 211 can drive the clamp head 203 to rotate, adjusting the spray angle of the nozzle. Assuming the spray distance when the water pressure is high is taken as the specified distance, when the water pressure is low, the clamp head 203 is adjusted to spray irrigation at a larger rotation angle, thereby avoiding the situation where the spray distance is too short due to the low water pressure, which would not be able to effectively irrigate the specified area.

[0032] When some water comes into contact with the toothed blade 208, leakage occurs. Specifically, some water cannot be effectively sprayed to the designated area with the water from the nozzle. The leaked water flows towards the upper surface of the rotating disk 201. Through the first sleeve 301, the leaked water accumulates inside the rotating disk 201 and the first sleeve 301. As the rotating disk 201 continues to swing, the centrifugal force causes the water to flow towards the outlet 303 into the water inlet space. During the rotation of the rotating disk 201, the swing rod 304 will also rotate. The swing arm 304 pushes the water into the water inlet space, causing the water to flow below the limiting plate 306. As the swing arm 304 squeezes, the water enters the water storage hood 307 through the one-way valve 308. During the continuous squeezing process, the water stored in the water storage hood 307 will accumulate more and more, which can effectively prevent leaked water from flowing to the ground and causing waste. When there is a lot of water stored in the water storage hood 307, it can flow to the slot 204 through the flow pipe 309 and be sprayed onto the irrigation area with the water sprayed from the nozzle.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
