Description

Technical Field

[0001] This invention relates to the field of municipal environmental protection technology, specifically to an environmentally friendly sprinkler system for municipal engineering. Background Technology

[0002] Water trucks are needed for dust suppression and cooling during municipal environmental maintenance.

[0003] Existing environmentally friendly sprinkler systems used in municipal engineering cannot be rotated in multiple directions, resulting in blind spots in the sprinkler system, uneven watering, and a small watering area.

[0004] Furthermore, the existing rotation adjustment device lacks an angle limiting structure, which makes it difficult to achieve a stable angle fixation after angle adjustment. This causes the sprinkler device to deflect and sway during operation, which, combined with the operation of the sprinkler truck, makes the sprinkler device even more unstable.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: Example 1:

[0032] An environmentally friendly sprinkler system for municipal engineering includes a lower base 19, a mist cannon 3, an adjustment component, and a drive component.

[0033] A mounting plate 1 is rotatably mounted on the lower base 19, and a rotation angle limiting component is provided between the lower base 19 and the mounting plate 1.

[0034] The circumferential spraying angle of the fog cannon 3 can be adjusted by rotating the mounting plate 1.

[0035] One end of the fog cannon 3 is rotatably mounted on the mounting plate 1, and the other end of the fog cannon 3 is provided with a lifting block 23. The adjustment assembly is mounted on the upper end of the mounting plate 1. The adjustment assembly includes an adjustment frame 11, a slider 20, an inclined rotating rod 10, and a top wheel 27. The adjustment frame 11 is fixed to the upper end of the mounting plate 1. A pair of fixed rods 22 are provided in the inner cavity of the adjustment frame 11. A pair of sliders 20 distributed in the front and rear are slidably mounted on the lower end of the fixed rods 22. The upper ends of the pair of sliders 20 distributed in the front and rear are rotatably connected to one end of the inclined rotating rod 10. The other end of the inclined rotating rod 10 is rotatably mounted on the lifting block 23. The upper end of the lifting block 23 is provided with a top wheel 27 that abuts against the outer arc of the lower end of the fog cannon 3.

[0036] The height of the slider 20 is limited by the fixed rod 22, and the lifting block 23 is driven to move up and down by setting the tilting rod 10, so that the top wheel 27 is positioned at the port of the fog cannon 3, thereby achieving the purpose of adjusting the port angle of the fog cannon 3.

[0037] The drive assembly includes a second motor 13, a rack 25, and a drive gear 33. A pair of parallel racks 25 are respectively provided on the outer wall of the opposite side of a pair of sliders 20 distributed in front and behind. The drive gear 33 rotates and meshes between the adjacent pair of racks 25. The lower end of the drive gear 33 is driven by the second motor 13.

[0038] By setting up a drive component, the second motor 13 is used to make the drive gear 33 rotate, which in turn drives the rack 25 to move laterally, pulls the slider 20 to move relative to it, drives the tilting rod 10 to rotate, and lifts the lifting block 23, thereby achieving the purpose of adjusting the angle of the fog cannon 3 port. Example 2:

[0039] Based on embodiment 1, a column 2 is provided at the upper end of the mounting plate 1, and a first hinge seat 4 is provided at the upper end of the column 2. The lower outer wall of one end of the fog cannon 3 is rotatably mounted on the first hinge seat 4. A limit frame 5 is provided on the column 2. The limit frame 5 is provided with a pair of side plates clamping the front and rear sides of the fog cannon 3. Adjacent side plates are fixedly connected by multiple sets of connecting rods 9 distributed in a circumferential array. An arc-shaped rotating groove 6 is provided on the side plate. A limit rotating block 7 is rotatably inserted into the rotating groove 6 on the outer wall of the end of the fog cannon 3.

[0040] By setting the rotating slot 6 and the limiting rotating block 7 together, the rotation angle of the port of the fog cannon 3 is limited, and the front and rear position of the fog cannon 3 is limited to prevent deviation. Example 3:

[0041] Based on embodiment 2, the lower arc outer wall of the fog cannon 3 is provided with an inclined groove 8, and the top wheel 27 is rotatably installed on the upper end of the lifting block 23, and the top wheel 27 is rotatably installed in the groove 8.

[0042] By setting the top wheel 27 and the slide groove 8 in coordination, smooth contact is achieved when the outer wall of the fog cannon 3 is squeezed upwards, thus avoiding squeezing and jamming. Example 4:

[0043] Based on embodiment 3, a first motor 12 is provided in the middle of the lower base 19. The output shaft of the first motor 12 is fixedly connected to the lower end of the mounting plate 1. A circular ring guide rail 15 is provided on the outer edge of the upper end surface of the lower base 19. A limiting rotation groove 30 is provided at the upper end of the circular ring guide rail 15. A rotating ring 17 is provided at the lower end of the mounting plate 1 and is rotatably inserted into the limiting rotation groove 30.

[0044] By setting the limiting rotation groove 30 and the rotating ring 17 together, the outer edge of the mounting plate 1 is supported, thereby using the circular guide rail 15 to limit the rotation position. Example 5:

[0045] Based on embodiment 4, the lower end of the mounting plate 1 is provided with an upwardly recessed mounting groove, and a fixing plate 32 is provided in the mounting groove. A spring tube 31 is vertically provided at the lower end of the fixing plate 32, and a positioning pin 18 is telescopically installed at the lower end of the spring tube 31. A positioning groove 14 corresponding to the positioning pin 18 is provided on the lower base 19, and the lower end of the positioning pin 18 is vertically inserted and pressed into the positioning groove 14.

[0046] By setting the spring tube 31, the positioning pin 18 is kept under downward pressure, thereby making the positioning pin 18 vertically and tightly pressed into the positioning groove 14, thus fixing the rotation angle of the mounting plate 1.

[0047] The limiting assembly includes a right-angle side frame 16 and a traction rope 29. A pair of right-angle side frames 16, symmetrically arranged on the left and right, are vertically inserted into both ends of the mounting plate 1. One end of the right-angle side frame 16 is connected to a swivel ring 17, and the other end of the right-angle side frame 16 is connected to a spring tube 31 through the traction rope 29. A telescopic rod 28 is provided at the lower end of the right-angle side frame 16.

[0048] The right-angle side frame 16 is driven to rise and fall by setting the telescopic rod 28. When rising, the rotating ring 17 and the traction rope 29 are driven to rise, so that the rotating ring 17 and the limiting rotation groove 30 are separated, which facilitates the circumferential rotation adjustment. The traction rope 29 drives the spring tube 31 to be compressed, which drives the positioning pin 18 to rise, which facilitates the adjustment of the circumferential angle of the mounting plate 1.

[0049] After adjustment, the resetting of the telescopic rod 28 causes the rotating ring 17 to press against the lower inner wall of the limiting rotating groove 30 for stable support. The resetting elastic force of the spring tube 31 achieves vertical compression and fixation of the positioning pin 18. Example 6:

[0050] Based on embodiment 5, the inner cavity of the adjusting frame 11 is set as an adjusting inner cavity 21, and the slider 20 is slidably installed in the adjusting inner cavity 21. The upper end of the slider 20 is provided with a second hinge seat 24 that is rotatably connected to the tilting rod 10. The other end of the tilting rod 10 is rotatably connected to the lifting block 23. The upper end of the slider 20 is provided with a pair of limiting grooves 26, which are directly opposite the fixed rod 22. The limiting grooves 26 slide against the arc outer wall of the fixed rod 22.

[0051] The tilting rod 10 is rotated and installed by setting a second hinge seat 24, and the slider 20 is limited to a lateral sliding position by setting a limiting groove 26 to prevent the slider 20 from falling off.

[0052] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
