Description

Technical Field

[0001] The present invention relates to the technical field of greening maintenance, and specifically relates to a greening maintenance sprinkler device convenient for angle control. Background Art

[0002] With the acceleration of the urbanization process, the continuous expansion of the urban greening area, and the increasing public demand for the quality of the ecological environment, the importance of greening maintenance work has become increasingly prominent. Existing landscaping maintenance devices usually use sprinkler heads to spray and maintain the garden. Among them, the spraying angle of the sprinkler head is fixed, and the spraying range is also relatively fixed.

[0003] The patent with the publication number CN221689597U discloses a greening maintenance construction device. When it is necessary to adjust the spraying, by starting the driving component, the lifting push rod and the bottom support plate rotate relative to each other, and then the moving push rod drives the rotating disk to rotate through the extending rod, so as to realize the adjustment of the horizontal spraying angle. Moreover, the lifting push rod and the telescopic push rod can be started to drive the connecting block and the fixed block to move up or down, and then drive the moving push rod and the extending rod to lift synchronously, so as to realize the adjustment of the spraying height. In addition, the lifting push rod or the telescopic push rod can be started separately to realize the adjustment of the angle of the extending rod, and then drive the adjustment of the angle of the rotating disk to realize the adjustment of the vertical spraying angle.

[0004] Although the above solution realizes the adjustment of the horizontal spraying angle and the vertical spraying angle, to achieve the above adjustments, multiple driving devices need to be installed on the greening maintenance construction device. When the greening maintenance construction device is fixedly installed and used outdoors, the driving devices are easily damaged when exposed to the external environment, resulting in a relatively high maintenance cost of the greening maintenance construction device.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. The present invention is provided with a water supply pipe, a spraying structure, an angle adjustment structure, a water pressure control structure, and a rotating mechanism. The rotating mechanism enables the water supply pipe to rotate around its own axis, which helps to cover the surrounding greening area. Through the bearing plate, the transmission column, and the linkage structure, the function of automatically adjusting the spraying angle of the nozzle according to the change of the water pressure in the water supply pipe is realized. When the water pressure is low, the spraying range of the nozzle is limited. When the water pressure gradually increases, the bearing plate rises under the action of pressure, drives the adjusting arm to rotate through the transmission column and the linkage structure, and makes the angle between the nozzle and the ground gradually increase, expanding the spraying range. The use of a driving device at the nozzle is avoided, the equipment structure is simplified, and the cost is reduced.

[0018] 2. The present invention is provided with an angle limiting plate, which controls the rotation range of the adjusting arm and avoids the problem of the spraying range being reduced due to too high spraying height. Under the control of the angle limiting plate on the adjusting arm, as the water pressure continues to increase, the spraying range of the nozzle at a fixed angle is further expanded. While keeping the angle between the nozzle and the ground stable, the spraying range is maximized, realizing uniform coverage of a larger greening area.

[0019] 3. The present invention provides an arc-shaped frame and a self-adjusting component. The arc-shaped frame provides effective support for the hose. Under the action of the self-adjusting component, the hose can fit the arc-shaped frame and smoothly transition along its path, avoiding the disorderly swing or local folding of the hose due to lack of support during the movement of the adjusting arm, ensuring the continuous reliability of the hose in a dynamic environment, reducing the change in water flow velocity caused by physical deformation, and thus ensuring the smoothness and stability of the water flow.

Detailed implementation manners

[0031] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation manners.

[0032] Refer to Figures 1 to 10As shown: A greening maintenance sprinkler device with convenient angle control, including a water supply pipe 1, a pressure-regulating water pump 2, a sprinkling structure 3, an angle adjustment structure 4, a water pressure control structure 5, and a rotating mechanism 6; the water supply pipe 1 is vertically arranged, and several water outlets 11 are opened in the lower half of the water supply pipe 1; the pressure-regulating water pump 2 is arranged at the lower end of the water supply pipe 1; there are several sprinkling structures 3, and several sprinkling structures 3 respectively correspond to several water outlets 11. The sprinkling structure 3 includes a hose 31 and a sprinkler head 32, and both ends of the hose 31 are respectively connected to the water outlet 11 and the sprinkler head 32; the angle adjustment structure 4 is arranged in the middle of the water supply pipe 1, and the angle adjustment structure 4 includes several adjusting arms 41. One end of the adjusting arm 41 is axially connected to the side wall of the water supply pipe 1, and the sprinkler head 32 is installed at the other end of the adjusting arm 41; the water pressure control structure 5 is arranged at the upper end of the water supply pipe 1, and the water pressure control structure 5 includes a bearing plate 51, a transmission column 52, and a linkage structure 53. The bearing plate 51 is arranged inside the water supply pipe 1, and the diameter of the bearing plate 51 is the same as the inner diameter of the water supply pipe 1. A sealing plug 511 is arranged on one side of the bearing plate 51. The transmission column 52 is coaxially arranged with the water supply pipe 1. One end of the transmission column 52 is connected to the bearing plate 51, and the other end of the transmission column 52 passes through the end of the water supply pipe 1 and is connected to the linkage structure 53. The linkage structure 53 connects several adjusting arms 41 with the transmission column 52. The linkage structure 53 includes a linkage disk 531, several fixed arms 532, and several rotating arms 533. The linkage disk 531 is connected to the transmission column 52. Several fixed arms 532 are annularly arranged around the linkage disk 531. One end of the fixed arm 532 is connected to the linkage disk 531. Several rotating arms 533 respectively correspond to several fixed arms 532. Both ends of the rotating arm 533 are respectively axially connected to the fixed arm 532 and the adjusting arm 41; the rotating mechanism 6 is arranged at the lower end of the pressure-regulating water pump 2.

[0033] When the water pressure in the water supply pipe 1 is relatively low, the pressure on the bearing plate 51 is small and will not drive the transmission column 52 and the linkage structure 53 to move. At this time, the nozzle 32 may face the ground and the spraying range is limited. When the pressure regulating water pump 2 is started and the water pressure in the water supply pipe 1 is gradually increased, the vertically upward pressure on the bearing plate 51 increases, pushing the bearing plate 51 to move upward. The bearing plate 51 drives the linkage structure 53 to rise through the transmission column 52. The rotating arm 533 in the linkage structure 53 then drives the adjusting arm 41 to rotate around its axis connection with the water supply pipe 1, so that the angle between the nozzle 32 and the ground gradually increases. At the same time, the larger water pressure expands the spraying range of the nozzle 32. In addition, the rotating mechanism 6 is arranged at the lower end of the pressure regulating water pump 2 to drive the water supply pipe 1 to rotate around its own axis, ensuring full coverage of the surrounding greening area. As the water pressure in the water supply pipe 1 changes, the pressure on the bearing plate 51 and the moving distance are different, and the swinging amplitude of the adjusting arm 41 driven by the transmission column 52 and the linkage structure 53 also changes accordingly, thereby changing the spraying angle of the nozzle 32, so as to realize the adjustment of the spraying angle of the nozzle 32 directly driven by the water pressure change, avoiding the use of a driving device, simplifying the equipment structure and reducing the cost.

[0034] Refer to Figure 3 and Figure 4 As shown: The angle adjustment structure 4 further includes a plurality of angle limit plates 42. The plurality of angle limit plates 42 respectively correspond to a plurality of adjusting arms 41. The angle limit plates 42 are arranged at the axis connection of the adjusting arm 41 and the side wall of the water supply pipe 1. The angle limit plate 42 includes two limit plate bodies 421, and one end of the adjusting arm 41 is located between the two limit plate bodies 421.

[0035] During the process of the gradual increase of the water pressure in the water supply pipe 1, the pressure on the bearing plate 51 increases accordingly, and then drives the adjusting arm 41 to rotate around its axis connection with the water supply pipe 1 through the transmission column 52 and the linkage structure 53. As the adjusting arm 41 rotates, the angle between the nozzle 32 and the ground gradually increases, the spraying height of the nozzle 32 increases while the spraying range correspondingly decreases. In order to control the rotation range of the adjusting arm 41 and avoid the reduction of the spraying range caused by too high spraying height, angle limit plates 42 are arranged at the axis connection of the adjusting arm 41 and the water supply pipe 1. When the adjusting arm 41 rotates to contact the upper limit plate body 421, as the water pressure in the water supply pipe 1 further increases, the adjusting arm 41 is physically blocked by the limit plate body 421 and cannot continue to rotate. At this time, the angle between the adjusting arm 41 and the ground is maintained within a fixed range, ensuring the best balance between the spraying height and the spraying range of the nozzle 32. At the same time, as the water pressure continues to rise, the spraying range of the nozzle 32 at a fixed angle will be further expanded, thus avoiding the problem of the reduction of the spraying range caused by too high spraying height and further realizing the coverage of a larger greening area.

[0036] Refer to Figure 4 andFigure 5 As shown: The angle adjustment structure 4 further includes a guiding structure 43. An installation cavity for accommodating the guiding structure 43 is formed in the middle of the adjusting arm 41. The guiding structure 43 includes an arc-shaped frame 431 and two self-adjusting components 432; the arc-shaped frame 431 is arranged in the installation cavity, and the hose 31 is laid on the arc-shaped frame 431; the two self-adjusting components 432 are respectively arranged on both sides of the adjusting arm 41, and the two self-adjusting components 432 are connected to the arc-shaped frame 431.

[0037] When the adjusting arm 41 drives the nozzle 32 to move, the hose 31 may swing disorderly or be partially folded due to lack of effective support, thus affecting the water flow rate. By introducing the guiding structure 43, the hose 31 is placed on the arc-shaped frame 431, and the two self-adjusting components 432 can apply corresponding forces to the arc-shaped frame 431 according to the dynamic changes of the hose 31, ensuring that the hose 31 is closely attached to the arc-shaped frame 431. When the adjusting arm 41 moves, the hose 31 can smoothly transition along the path of the arc-shaped frame 431, avoiding the occurrence of disorderly movement and folding phenomena, thereby ensuring the smoothness and stability of the water flow.

[0038] Refer to Figure 5 and Figure 6 As shown: The guiding structure 43 further includes a plurality of rollers 433. The plurality of rollers 433 are arranged on the arc-shaped frame 431 at equal intervals.

[0039] When the hose 31 makes a smooth transition along the preset path of the arc-shaped frame 431, a large sliding friction is generated by the direct contact between the hose 31 and the arc-shaped frame 431. The hose 31 is usually made of rubber material, and the contact area between the hose 31 and the arc-shaped frame 431 is relatively large. This sliding friction not only increases the resistance of the hose 31 to move but also accelerates the wear of the hose 31. By arranging a plurality of rollers 433 on the arc-shaped frame 431, the hose 31 is placed on the plurality of rollers 433. When the adjusting arm 41 drives the nozzle 32 to move, the hose 31 moves accordingly and drives the rollers 433 to rotate, forming a rolling friction between the hose 31 and the rollers 433. Compared with the original sliding friction, the rolling friction reduces the resistance of the hose 31 to move, thereby reducing the wear of the hose 31 during the movement process and lowering the maintenance cost.

[0040] Refer to Figure 5 and Figure 6As shown: The self-adjusting component 432 includes a guide rod 4321, a slider 4322, and a first spring 4323; the guide rod 4321 is arranged in parallel beside the adjusting arm 41, and both ends of the guide rod 4321 are connected to the adjusting arm 41; the slider 4322 is slidably arranged on the guide rod 4321, and the slider 4322 is connected to the arc-shaped frame 431; the first spring 4323 is sleeved on the guide rod 4321, and both ends of the first spring 4323 are respectively abutted against the end of the guide rod 4321 and the side of the slider 4322.

[0041] When the adjusting arm 41 is in a static state, the two first springs 4323 in the two self-adjusting components 432 respectively exert forces on the two sliders 4322, and the resultant force of the two forces reaches a dynamic balance with the force generated by the water flow in the hose 31 on the arc-shaped frame 431, ensuring that the system remains in a stable state. When the adjusting arm 41 starts to move, the hose 31 moves accordingly. As the position of the hose 31 changes, the force exerted by the hose 31 on the arc-shaped frame 431 will also change accordingly. When the force exerted by the hose 31 on the arc-shaped frame 431 decreases, the first spring 4323 will utilize its stored elastic potential energy to push the slider 4322 to move along the guide rod 4321. The movement of the slider 4322 further drives the arc-shaped frame 431 to move synchronously with the hose 31. When the force exerted by the hose 31 on the arc-shaped frame 431 increases, the first spring 4323 can be compressed to keep the arc-shaped frame 431 moving synchronously with the hose 31, so as to realize that the hose 31 is continuously supported effectively.

[0042] Refer to Figure 3 and Figure 7 As shown: The water pressure control structure 5 further includes a second spring 54. The second spring 54 is sleeved on the transmission column 52, and both ends of the second spring 54 are respectively abutted against the end of the water supply pipe 1 and the bearing plate 51.

[0043] The downward force received by the bearing plate 51 mainly comes from its own weight, the weight of the transmission column 52, and the gravity of the linkage structure 53 connected thereto. When the water pressure acting on the bearing plate 51 exceeds the sum of these gravities, the bearing plate 51 will start to move upward, and once the water pressure exceeds this critical value, no matter how much the water pressure further increases, the bearing plate 51 will be pushed to the highest point within its movable range. In order to make the spraying range of the spray head 32 correspond to the water pressure, a second spring 54 is sleeved on the transmission column 52. As the water pressure gradually increases, the second spring 54 is compressed, and the downward reaction force it exerts on the bearing plate 51 also increases accordingly. When the water pressure reaches a certain stable state, the forces received on the upper and lower sides of the bearing plate 51 reach a dynamic balance. At this time, the bearing plate 51 will stop moving and maintain its current position. If the water pressure continues to increase, the bearing plate 51 will continue to move upward under the action of the water pressure until a new force balance state is reached, so as to realize different spraying ranges corresponding to different water pressures.

[0044] Refer to Figure 3 and Figure 8 As shown: A first air guide channel 521 is provided inside the transmission column 52 along its axial direction. The first air guide channel 521 communicates with the outside. A plurality of air holes 522 are provided at one end of the transmission column 52 connected to the bearing plate 51. The air holes 522 communicate with the first air guide channel 521.

[0045] A closed space is formed between the bearing plate 51 and the end of the water supply pipe 1. A certain amount of air is contained in this closed space. When the bearing plate 51 moves upward due to the external water pressure, the air in this closed space will be squeezed, thereby generating a resistance to the movement of the bearing plate 51. In order to effectively relieve this resistance, the air in the closed space will follow the principle of pressure gradient and flow towards the low-pressure area. Since the first air guide channel 521 is connected to the external space and the air pressure inside it can remain stable, the air in the closed space will enter the first air guide channel 521 through the air holes 522 and is finally discharged to the external environment, ensuring that the air pressure in the closed space is maintained at a relatively stable level, reducing the obstruction of the air to the movement of the bearing plate 51. When the bearing plate 51 resets under the change of external conditions, the external air can smoothly enter the closed space through the first air guide channel 521, effectively preventing the reduction of the internal air pressure of the space, thereby realizing the effective control of the air pressure in the closed space between the bearing plate 51 and the water supply pipe 1, and ensuring that the bearing plate 51 will not be disturbed by air pressure fluctuations during the movement.

[0046] Refer to Figure 3 and Figure 9 As shown: The water pressure control structure 5 further includes a protection structure 55. The protection structure 55 is provided at the end of the transmission column 52. The protection structure 55 includes an exhaust block 551 and a cover plate 552; a second air guide channel 5511 is provided in the middle of the exhaust block 551. The second air guide channel 5511 communicates with the first air guide channel 521. The upper end of the exhaust block 551 is frustum-shaped; the cover plate 552 is covered on the upper end of the exhaust block 551. A frustum-shaped inner cavity is provided inside the cover plate 552. A channel for gas flow is formed between the inner cavity of the cover plate 552 and the upper end of the exhaust block 551.

[0047] The upper end of the first air guide channel 521 is in an open state, and rainwater can enter the water supply pipe 1 from the first air guide channel 521, which easily causes corrosion of the bearing plate 51 and the like. By providing the protection structure 55, a gas flow channel that first slopes upward and then horizontally is formed between the inner cavity of the cover plate 552 and the upper end of the exhaust block 551. When gas enters the water supply pipe 1, the gas will first move upward along the side wall of the frustum-shaped part, and then move horizontally at the top of the frustum-shaped part, and finally enter the second air guide channel 5511. Since rainwater is only affected by gravity and will only fall downward and cannot move upward along the side wall of the frustum-shaped part, the rainwater is effectively blocked outside the protection structure 55, thus preventing rainwater from entering the interior of the water supply pipe 1.

[0048] Refer to Figure 3 and Figure 9 As shown: The protection structure 55 further includes an annular insect-proof net 553. The annular insect-proof net 553 is arranged between the exhaust block 551 and the cover plate 552, and the inner diameter of the annular insect-proof net 553 is larger than the inner diameter of the second air guide channel 5511.

[0049] In practical applications, since the equipment is usually installed in an outdoor environment, it faces the risk of invasion by foreign organisms such as flying insects. By adding the annular insect-proof net 553, when flying insects try to enter the water supply pipe 1, they will be tightly blocked outside by the annular insect-proof net 553, thus preventing them from entering the interior of the water supply pipe 1 and the possible pollution or blockage problems caused thereby.

[0050] Refer to Figure 1 and Figure 10 As shown: The rotating mechanism 6 includes a fixed plate 61, a main rotating shaft 62 and a rotation driver 63; the fixed plate 61 is horizontally arranged at the lower end of the pressure regulating water pump 2; the main rotating shaft 62 is arranged in the middle of the fixed plate 61, and the axis of the main rotating shaft 62 is collinear with the axis of the water supply pipe 1. One end of the main rotating shaft 62 is connected to the fixed plate 61 through a bearing, and the other end of the main rotating shaft 62 is fixedly connected to the pressure regulating water pump 2; the rotation driver 63 is arranged on one side of the main rotating shaft 62, and the rotation driver 63 is in transmission connection with the main rotating shaft 62.

[0051] In the spraying structure 3, there is a certain angle between two adjacent spray heads 32. Although the spray heads 32 can spray a fan-shaped spraying range, the overlapping area between these ranges is relatively limited. To make up for this deficiency, while the spraying structure 3 is working, the rotating mechanism 6 works, and the rotation driver 63 drives the main rotating shaft 62 to continuously rotate bidirectionally around its own axis. As the main rotating shaft 62 and the water supply pipe 1 swing, the spray heads 32 also change their spraying directions accordingly, and the blank areas between two adjacent spray heads 32 are fully covered, thus effectively expanding the spraying range and ensuring that the entire spraying area can be evenly and effectively sprayed.

[0052] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
