[0022] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0025] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] In this utility model, such as Figure 1-2As shown, a dust suppression spray device for construction is provided, installed on the top railing of a construction site. It includes a T-joint, comprising a first pipe head 1, a second pipe head 2 collinear with the first pipe head 1, and a third pipe head 4 with a nozzle 3 installed thereon. The axis of the third pipe head 4 is perpendicular to the axis of the first pipe head 1. A positioning rib 5 is provided on the T-joint near the third pipe head 4. The dust suppression device also includes a positioning frame 6, comprising a base 601 capable of abutting against the railing and a ring portion 602 connected to the base 601. The ring portion 602 allows the first pipe head 1 and the second pipe head 2 to pass through. The base 601 has a connecting portion connected to the railing. A first insertion portion is provided on the side of the ring portion 602 facing the positioning rib 5, and a second insertion portion is provided on the side of the positioning rib 5 facing the ring portion 602. The first insertion portion and the second insertion portion can be inserted and engaged, and the positioning frame 6 and the positioning rib 5 can have multiple insertion and engagement positions circumferentially along the axis of the first pipe head 1.

[0027] During installation, the dust suppression device of this invention involves fitting the ring 602 of the positioning frame 6 onto the first pipe head 1 or the second pipe head 2, with the base 601 of the positioning frame 6 abutting against the railing at the top of the enclosure. At this point, the nozzle 3 can be rotated to approximately face the desired direction, positioning the first and second insertion parts in a position where they can be inserted and engaged. The positioning frame 6 and positioning rib 5 can then be moved closer together to allow the first and second insertion parts to engage, and then connected to the railing via a connecting part. This arrangement ensures that the installed dust suppression spray device can be directionally positioned using the mutually engaging first and second insertion parts to prevent changes in the spray direction.

[0028] It should be noted that in the application scenarios of this utility model, the direction of the nozzle is approximate, and the precision requirements are relatively lenient. For example, the nozzle can be arranged obliquely upwards towards the inside of the enclosure, and the angle between the nozzle axis and the vertical line can be controlled between 10° and 45°. Through the dust suppression device of this utility model, the arrangement and orientation of the nozzle can be constrained to a certain range, which can reduce the possibility of significant changes in the nozzle orientation.

[0029] The improvement of this utility model lies in the constraint structure of the nozzle orientation. The connection method between the first pipe head 1, the second pipe head 2 and the water distribution pipe, and the installation method of the nozzle on the third pipe head 4 are not improved. Those skilled in the art can flexibly choose feasible implementation methods when implementing the invention.

[0030] The accompanying drawings of this utility model are further described below, as follows: Figure 1 In the middle, the water distribution pipes on both sides of the tee joint are partially shown, and the positioning bracket 6 and positioning rib 5 on the right side are not yet inserted and fitted.

[0031] In the illustrated embodiment, more specifically, the first insertion part is configured as a post 7, and the second insertion part is configured as an insertion hole 8 formed in the positioning rib 5.

[0032] As shown in the figure, the use of the insertion post 7 and the insertion hole 8 can improve the stability of their insertion and positioning. In an optional embodiment, the insertion post 7 can also be interference-fitted into the insertion hole 8 to prevent the positioning frame 6 from separating from the positioning rib 5.

[0033] In alternative embodiments, other forms of the first insert portion and the second insert portion may also be used, such as the ring portion 602 and the positioning rib 5 being both configured as end face gears, with the teeth of the end face gears forming the first insert portion and the second insert portion.

[0034] In a preferred embodiment, specifically regarding the structure of this invention, the insertion post 7 is a metal insertion post 7, and the base 601 is a plastic base 601. The metal insertion post 7 and the base 601 are connected by injection molding. Using a metal insertion post 7 ensures the strength of the insertion post 7 and improves the insertion stability of the first insertion part and the second insertion part.

[0035] In the illustrated embodiment, more specifically regarding the structure of this utility model, the ring portion 602 is provided with a plurality of insert posts 7 spaced apart along its circumference; the positioning rib 5 is arranged around the second tube head, and the positioning rib 5 is provided with a plurality of insertion holes 8 spaced apart along its circumference.

[0036] In the illustrated embodiment, to further specify the structure of this utility model, the base 601 has a through hole for the cable tie to pass through, and the through hole forms the connecting part.

[0037] As shown in the figure, the bottom surface of the base 601 is set as a plane, so that during installation, the bottom surface of the base 601 can be attached to the railing, and the base 601 can be tied and fixed to the railing by passing cable ties through the through holes of the base 601.

[0038] In alternative embodiments, other forms may be used to fix the connecting part to the railing, such as the base 601 being integrally formed as the connecting part, or by using self-tapping screws to connect it to the railing.

[0039] In the illustrated embodiment, specifically regarding the structure of this utility model, the positioning rib 5 and the tee connector are separate structures. This allows the use of existing tee connectors without requiring modifications to the processing molds.

[0040] In the illustrated embodiment, more specifically regarding the structure of this utility model, the positioning rib 5 is sleeved on the first pipe head 1 or the second pipe head 2, and the positioning rib 5 is provided with a positioning rod 9 extending to the side of the third pipe head 4.

[0041] As shown in the figure, a ring-shaped positioning rib 5 structure is adopted. During assembly, the positioning rib 5 is inserted into the first pipe head 1 or the second pipe head 2, so that the positioning rod 9 extends to the side of the third pipe head 4. In this way, the positioning rod 9 can provide a constraint force to the tee joint.

[0042] In the illustrated embodiment, the positioning ribs 5 are arranged in a more specific manner, wherein the positioning ribs 5 are configured as a first positioning rib 5 and a second positioning rib 5, the first positioning rib 5 is integrally connected to the positioning rod 9, and the second positioning rib 5 is provided with a positioning hole 10 for the positioning rod 9 to be inserted.

[0043] As shown in the figure, during assembly, the first positioning rib 5 and the second positioning rib 5 can be fitted onto the first tube head 1 and the second tube head 2 respectively, and the positioning rod 9 can be inserted into the positioning hole 10, thereby completing the constraint of the positioning rib 5 on the tee joint.

[0044] Regarding the connection method between the positioning rib 5 and the tee connector, in an optional embodiment, the positioning rib 5 can be bonded to the tee connector.

[0045] Alternatively, the positioning rib 5 and the tee connector can be configured such that the positioning rib 5 and the tee connector are integrally formed and connected.

[0046] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0047] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
