For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the accompanying drawings of the specification and in combination with specific situations.

[0032] The existing construction site sprinkler devices mainly use directional spraying or swinging spraying; if the angle needs to be adjusted for other angles, the overall device needs to be adjusted in angle, and its effect efficiency is low and the accuracy is not ideal; therefore, please refer to Figures 1-4 For this reason, the present utility model provides a technical solution: an adjustable spraying mechanism for construction engineering construction, which includes a frame 1, and a driving mechanism 2 is arranged inside the frame 1;

[0033] Among them, the driving mechanism 2 outputs three sets of coaxial rotational degrees of freedom for driving the adjusting mechanism 3 to perform universal angle adjustment; at the same time, the adjusting mechanism 3 is used to connect the external water spray pipe and perform universal adjustment on the spraying angle of the water spray pipe based on the driving mechanism 2.

[0034] In some specific embodiments of the present application, please refer to Figures 1-2 : A fixture 4 is arranged outside the frame 1 for placing the overall device in the external environment.

[0035] In this solution, the fixture 4 can be selected as an electric type or a manual mechanical type, mainly used to fix the overall device on external fixed structures such as railings and upright frames. By only connecting the water pipe to this device through an external water pump, the spraying adjustment function can be realized; or by fixing the overall device on the spraying port of a large spraying device such as a sprinkler irrigation machine and participating in its spraying as an additional device;

[0036] In some specific embodiments of the present application, please refer to Figures 3-4 : The driving mechanism 2 includes three power components 201 and three worm and worm gear assemblies 203 driven by the three power components 201;

[0037] Among them, the worm and worm gear assembly 203 is used to generate rotational degrees of freedom.

[0038] At the same time, the adjusting mechanism 3 includes three hollow rotating shafts 301; the worm and worm gear assembly 203 includes a worm and a worm gear that mesh with each other, and the worm is driven to rotate by the power component 201; the worms of the three worm and worm gear assemblies 203 are stacked up and down and share a central axis, and the hollow rotating shafts 301 also share the central axis of the worm gear; one worm gear is fixedly matched with one hollow rotating shaft 301 to output rotational degrees of freedom to the adjusting mechanism 3.

[0039] It should be noted that in this specific embodiment, the hollow rotating shafts 301 and the worm and worm gear assemblies 203 determine the number of rotational degrees of freedom of the present device as described above; the more the number, the more angles, efficiency, and accuracy that the present device can adjust; but based on the universal adjustment function as the basis, the number of the above devices is at least three;

[0040] In this solution, the power component 201 is a servo motor for driving the worm.

[0041] In some specific embodiments of the present application, please refer to Figures 3-4 : The diameters of the three hollow rotating shafts 301 are different, and they are rotationally fitted in a mutually covering manner; among them, the hollow rotating shaft 301 with the largest diameter is fixedly connected to the worm gear farthest from the adjusting mechanism 3, and the hollow rotating shaft 301 with the smallest diameter is fixedly connected to the worm gear closest to the adjusting mechanism 3.

[0042] In this solution, based on the above structural features, the three groups of hollow rotating shafts 301 will not have mechanical interference, and at the same time, the three groups of worm gears that cooperate up and down will not have mechanical interference; at the same time, based on the above cooperation conditions, the adjusting mechanism 3 further includes a hinge arm 302 and a connecting platform 303; the hinge arm 302 is fixedly fitted to the hollow rotating shaft 301, and the heights of each hinge arm 302 are different and are all hinged to the outer surface of the connecting platform 303.

[0043] In this solution, when the servo motor drives the adjusting hollow rotating shaft 301 to drive the hinge arm 302, and the position of each group of hinge arms 302 changes, the angle of the connecting platform 303 can be adjusted; the outer surface of the hollow rotating shaft 301 with the largest diameter is rotationally fitted to the connecting frame 202, and the connecting frame 202 is fixedly fitted to the frame 1;

[0044] It can be understood that in this specific embodiment, if the driving time or speed of the three servo motors is driven according to a rule, the hinge arm 302 can be driven to realize the universal angle adjustment of the connecting platform 303 along a certain spatial movement trajectory;

[0045] Preferably, the device further includes a controller, and the controller pre-programs to control the servo motor; interacts with the staff through the pre-programmed program to determine the actual angle of the connecting platform 303; or drives the servo motor in a forward and reverse driving mode for a certain time through pre-programming control to control the connecting platform 303 to be driven in a swinging form, so as to realize the selection of the corresponding angle or mode for the external water spray pipe;

[0046] It can be understood that in this specific embodiment, since the connecting platform 303 is directly connected to the external water spray pipe, in order to avoid the external water spray pipe from being wound, each drive of the servo motor should not exceed 360°;

[0047] In some specific embodiments of the present application, please refer to Figures 3-4 : The connecting platform 303 is detachably connected to the external water spray pipe through a coupling 304, and can be adapted to water pipes with different diameters at the same time.

[0048] The technical features of the above-described specific embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above specific embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0049] The above-described embodiments only express the implementation modes of the relevant practical applications of the present utility model. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
