[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following detailed description of the specific embodiments of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] The present application provides a spliced drainage unit. Refer to Figure 1 , the spliced drainage unit includes a drainage component, an angle adjustment plate 200, a support rod, and a base 400 that are sequentially connected in a first direction. The first direction can be understood as the components of the spliced drainage unit being installed in one direction, such as along the axial direction of the support rod. After the spliced drainage unit is constructed and installed, the support rod is usually in a vertical state.

[0033] Refer to Figure 1, the drainage assembly includes a sink body 100. One side of the sink body 100 has a drainage groove, and the radial cross-sectional property of the drainage groove can be rectangular or an arc surface (such as a semi-circle). The drainage groove can accommodate water flow through. The side of the sink body 100 facing away from the drainage groove has a connecting portion 110.

[0034] In some embodiments, referring to Figure 1 , the side of the sink body 100 facing away from the drainage groove has a reinforcing rib, and the reinforcing rib forms the connecting portion 110. The reinforcing rib can enhance the strength of the sink body 100. Using the reinforcing rib as the component connected to the angle adjustment plate 200 makes the structure of the spliced drainage unit more concise.

[0035] The number of the connecting portions 110 can be set according to the axial length of the sink body 100, its mass, and the designed service life of the drainage channel. For example, when the axial length of the sink body 100 is short and its mass is light, the number of the connecting portions 110 can be one, for example, set in the middle of the axial direction of the sink body 100. Also, the number of the angle adjustment plates 200, support rods, and bases 400 connected by the connecting portion 110 can also be set according to the axial length and mass of the sink body 100. For example, when the axial length is short and the mass is light, the connecting portion 110 only connects a set of angle adjustment plate 200, support rod, and base 400

[0036] When the axial length of the sink body 100 is long and its mass is heavy, in some embodiments, the number of the connecting portions 110 is at least two. The connecting portions 110 are distributed along the axial direction of the sink body 100. Any one of the connecting portions 110 includes at least two connection points, and each connection point is sequentially connected to the corresponding angle adjustment plate 200, support rod, and base 400.

[0037] Referring to Figure 1 , the sink body 100 includes a first end and a second end extending along the axial direction, that is, at least one connecting portion 110 can be provided at the first end and the second end respectively. Each connecting portion 110 is connected to at least two sets of corresponding angle adjustment plates 200, support rods, and bases 400.

[0038] In some embodiments, referring to Figure 1 and Figure 7 , the sink body 100 includes a first end and a second end extending along the axial direction. The first end has a first splicing portion 120, and the second end has a second splicing portion 130 that can be cooperatively connected to the first splicing portion 120.

[0039] The sink body 100 can be connected end to end along its own axial direction. That is, adjacent sink bodies 100 can be connected end to end along their own axial directions, and the connection between adjacent drainage grooves has a smooth transition, or there is no obvious drop, such as when they are completely aligned and joined together.

[0040] Exemplarily, the first splicing portion 120 is a slot, and the second splicing portion 130 is a mounting groove. The concave portion of the slot corresponds to the convex portion of the mounting groove, and the convex portion of the slot corresponds to the concave portion of the mounting groove. In this way, when adjacent splicing drainage channels are spliced, the water tank body 100 is convenient to splice, and the adjacent two drainage grooves are basically integrated, with a smooth and flat interior.

[0041] The direction of the convex or concave of the slot and the mounting groove can be along the radial direction of the water tank body 100. In this way, the length of the slot and the mounting groove along the axial direction can be set longer, and the combination between adjacent water tank bodies 100 is relatively firm.

[0042] Of course, the direction of the convex or concave of the slot and the mounting groove can be along the axial direction of the water tank body 100. The length of the slot and the mounting groove along the axial direction can be set shorter, and adjacent water tank bodies 100 are easy to align and convenient to install and combine.

[0043] Also exemplarily, both the first splicing portion 120 and the second splicing portion 130 are annular convex edges, such as flange plates, and are connected by flange connection. For another example, two annular convex angle adjustment plates 200 extend along the axial direction of the water tank body 100 and are connected to the edges by an adhesive connection method.

[0044] In some embodiments, referring to Figure 1 , on the top of the water tank body 100, a mounting seat 140 for installing a rain grate is provided at the edge of the drainage groove.

[0045] Referring to Figure 5 and Figure 6 , the angle adjustment plate 200 extends along the axial direction of the water tank body 100 and is connected to the connecting portion 110. The angle adjustment plate 200 is provided with an adjustment groove 210 having an included angle with the first direction. The support rod includes a support rod body 310 and a connecting rod 320. The connecting rod 320 is fixed on the support rod body 310 and extends into the adjustment groove 210 and moves and is limited within the path formed by the adjustment groove 210. The length of the support rod in the first direction can be adjusted.

[0046] Referring to Figure 5 and Figure 6, the support rod body 310 is connected to the angle adjustment plate 200 through the connecting rod 320 passing through the adjustment slot 210. The adjustment slot 210 has an angle with the first direction, so it has different heights in the first direction. The connecting rod 320 can slide within the adjustment slot 210, and its movement path is determined by the shape of the adjustment slot 210, and the movement direction is not along the first direction. Therefore, when the connecting rod 320 moves to different positions, the relative position relationship between the support rod body 310 and the angle adjustment plate 200 changes, so the included angle between the two in the plane where the angle adjustment plate 200 is located changes, and then the connecting rod 320 is locked for limit, so that the support rod body 310 and the angle adjustment plate 200 are fixed. Reflecting on the drainage assembly, that is, the pitch angle of the drainage assembly is adjusted accordingly, so as to adjust the inclination angle of the drainage channel.

[0047] The connecting rod 320 can be a bolt structure, and the width of the adjustment slot 210 matches the bolt. When the bolt therein slides to the required position within the adjustment slot 210, tighten the nut to fix and limit the bolt.

[0048] The adjustment slot 210 can be a straight slot, so that the angle between the adjustment slot 210 and the first direction can be the angle between the extension direction of the adjustment slot 210 and the first direction, such as 15°, 33°, 50°, etc.

[0049] The adjustment slot 210 can also be an arc slot. In this way, the angle between the adjustment slot 210 and the first direction can be the angle between the tangent direction of the adjustment slot 210 and the first direction, such as 15°, 33°, 60°, etc.

[0050] In some embodiments, refer to Figure 5 and Figure 6 , the adjustment slot 210 is an arc slot, and the highest point or the lowest point of the arc slot does not lie at the end point of the arc slot.

[0051] The shape of the arc slot can be convex upward, such as gradually rising from one end to the highest point and then gradually descending to the other end. The shape of the arc slot can be concave downward, such as gradually descending from one end to the lowest point and then gradually rising to the other end. In either of the above ways, the angle adjustment plate 200 can swing and adjust the angle relative to the left and right sides of the highest point or the lowest point of the arc slot, so a larger angle adjustment range can be achieved.

[0052] In some embodiments, refer to Figure 5 and Figure 6 , the arc slot is a symmetric structure, and the arc slot is symmetrically arranged about its highest point or lowest point. The angle adjustment plate 200 can rotate along the horizontal axis, and the adjustable angles of the angle adjustment plate 200 relative to the left and right sides of the highest point or the lowest point of the arc slot are the same, and the adjustment range is larger.

[0053] The above-mentioned spliced drainage unit includes a drainage component, an angle adjustment plate 200, a support rod, and a base 400 that are sequentially connected in the first direction. Assembling multiple spliced drainage units can form a drainage channel, and the construction process is simple. Moreover, according to the actual situation of the project site, by adjusting the included angle between the angle adjustment plate 200 and the support rod and the height of the support rod, the height of the drainage component and the inclination angle can be adjusted accordingly, and then the adjustment of the drainage channel can be completed. The above-mentioned spliced drainage unit has a simple structure, a simple construction process, a fast construction progress, and saves manpower and material resources. And the construction adjustment difficulty is small, and the plasticity and maintainability are good.

[0054] Moreover, the above-mentioned spliced drainage unit has the advantages of convenient and fast construction and assembly, low requirements for the terrain at the construction site, no need to excavate drainage ditches, and can be recycled and reused after drainage.

[0055] According to some embodiments of the present application, refer to Figure 5 and Figure 6 , the angle adjustment plate 200 includes a mounting plate 220 and two connecting pieces 230 that are opposite and spaced apart. The mounting plate 220 is connected to the connecting portion 110.

[0056] The mounting plate 220 can be connected to the connecting portion 110 through fixing plates 240. There are two fixing plates 240, which are respectively arranged on both sides of the connecting portion 110. The fixing plate 240 can be an angle bracket, and the angle bracket includes two perpendicular surfaces. One surface is fixedly connected to the connecting portion 110 through a fastener such as a bolt, and the other surface is fixedly connected to the mounting plate 220 through a fastener such as a bolt. Of course, the two angle brackets can also be fixedly connected through the same bolt passing through the connecting portion 110.

[0057] The two connecting pieces 230 are located on the side of the mounting plate 220 away from the connecting portion 110, and both are provided with adjustment slots 210. The support rod body 310 extends between the two connecting pieces 230 and is connected through a connecting rod 320. In this connection method, the angle adjustment plate 200 is evenly stressed, and the support rod body 310 rotates smoothly.

[0058] In some embodiments, refer to Figure 1 and Figure 2 , the support rod body 310 includes a support vertical rod 311, a lead screw 312, and a locking nut 313. The support vertical rod 311 is connected to the angle adjustment plate 200. The lead screw 312 is sleeved in the support vertical rod 311 and can move axially relative to the support vertical rod 311 and is locked and limited through the locking nut 313.

[0059] One end of the lead screw 312 is inserted into the rod body of the support vertical rod 311, and the other end is exposed outside the support vertical rod 311 to connect to the base 400. Adjust the exposed length of the lead screw 312, and then lock and limit it by tightening the lock nut 313. At this time, the lead screw 312 cannot move further. In this way, the height of the support rod body 310 is adjusted, and then the height of the drainage component is adjusted. When a drainage component is connected to several sets of angle adjustment plates 200, support rods, and bases 400 at the same time, at this time, when the heights of different support rod bodies 310 are different, the inclination angle of the drainage component is also adjusted.

[0060] The base 400 can be divided into a ground-inserted base 400 used in soil layers and a flat base 400 used on a concrete cushion or in a rock formation according to the foundation type.

[0061] In some embodiments, refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The circumferential part of the support vertical rod 311 is provided with an insertion plate 314, and the insertion plate 314 is provided with a plurality of mounting holes distributed along the circumferential direction of the insertion plate 314. The spliced drainage unit further includes an inclined rod, a horizontal rod 500, and a disc buckle pin 600. The inclined rod and the horizontal rod 500 are connected between two adjacent support columns. The end of the horizontal rod 500 is provided with a disc buckle clip 510, the disc buckle clip 510 is provided with a plug hole, and the disc buckle clip 510 is fixed by passing the disc buckle pin 600 through the plug hole and the mounting hole.

[0062] Adjacent support vertical rods 311 within the same spliced drainage unit or adjacent support vertical rods 311 in different spliced drainage units can be connected by inclined rods and horizontal rods 500. In this way, a support system is formed, making the overall structure of the spliced drainage unit or drainage channel more firm and safer.

[0063] The height of the insertion plates 314 of adjacent support vertical rods 311 can be made the same by adjusting the lead screw 312. In this way, the horizontal direction of the support vertical rods 311 is connected by the horizontal rod 500 to stabilize the support system. The connection between the support vertical rod 311 and the connecting rod 320 is composed of an insertion plate 314 fixed outside the support vertical rod 311, a disc buckle clip 510 at the end of the horizontal rod 500, and a movable disc buckle pin 600. The end of the disc buckle pin 600 is slightly larger than the aperture of the insertion plate 314 to prevent it from falling off during transportation.

[0064] The inclined rod connects the insertion plates 314 of different support vertical rods 311 at different heights. The connection method of the inclined rod is similar to that of the horizontal rod 500 and will not be elaborated here.

[0065] The plug tray 314 is provided with a plurality of mounting holes distributed circumferentially along the plug tray 314. In this way, the same support vertical rod 311 can be horizontally connected to multiple other support vertical rods 311 in the horizontal direction through the horizontal rod 500, and can be obliquely connected to multiple other support vertical rods 311 through the diagonal rod. Thus, the support volume is more stable.

[0066] The present application also provides a drainage channel. Refer to Figure 1 , which includes a plurality of spliced drainage units and buckles. The adjacent sink bodies 100 are connected end to end and fixed by buckles.

[0067] According to the actual situation of the drainage channel, T-shaped and cross-shaped connection units can be set. The adjacent sink bodies 100 of the spliced drainage units are connected end to end and fixed by buckles.

[0068] In order to enhance the sealing performance, a sealing rubber layer for maintaining the seal can also be provided between the installation groove and the insertion slot.

[0069] The following describes the application construction method of the drainage channel in an embodiment, which specifically includes the following steps:

[0070] Before construction, first assemble the support system, fix the base 400 on the soil layer, and adjust the height of the support rod according to the required height;

[0071] Place a plurality of drainage components on the support system, and connect the adjacent drainage components end to end in sequence and connect them by buckles.

[0072] Connect each drainage component to the angle adjustment plate 200, appropriately adjust the angle adjustment plate 200 according to the drainage angle, so that the drainage groove has a slight inclination to facilitate drainage. After the angle is adjusted, fix it through the connecting rod 320;

[0073] After the installation of the spliced drainage unit is completed, rain grates and other beautification operations can be installed according to the site needs.

[0074] After the spliced drainage unit is used up, it is disassembled in reverse order according to the installation sequence.

[0075] The above-described embodiments only express several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent 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 deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
