A composite resin drainage ditch with corner splicing structure and its assembly method

Abstract

This invention discloses a composite resin drainage ditch with a corner splicing structure and its assembly method, belonging to the field of drainage ditch technology. To solve the problems of cumbersome installation and poor adaptability of corner drainage ditches, the stretching channel has a folded structure, with two splicing joints located at both ends. When splicing at the corner of the drainage ditch, the stretchable channel can be used directly to achieve the corner bend, eliminating the need for cutting and splicing. This allows for curved obstacle avoidance or corner turning when dealing with corners, improving splicing efficiency. The sliding outer and inner cover plates allow for adjustment of the overall size of the top cover, adapting to the actual laying length and angle. This enhances the overall adaptability of the top cover, accommodating various bending angles and lengths of the drainage ditch without the need for cutting or splicing, improving assembly convenience and installation efficiency.

Description

Technical Field

[0001] This invention relates to the field of drainage ditch technology, and in particular to a composite resin drainage ditch with a corner splicing structure and its assembly method. Background Technology

[0002] Drainage ditches refer to ditches that divert water collected in low-lying areas near roadbeds, farmland, and residences to areas outside the roadbed, farmland, and residences. In the field of drainage ditch design, there are already relevant patents. For example, application number CN202121472910.1 discloses a high-performance, modular resin drainage ditch. The bottom of the resin drainage ditch has symmetrically integrally formed support plates on both the left and right sides. An installation plate is integrally formed on the left side of the resin drainage ditch, and an installation groove is opened on the right side. The installation plate and the installation groove are fitted together. Baffles are symmetrically fixed to the upper front and rear outer walls of the resin drainage ditch, and fixing plates are provided on the lower side of each baffle. The fixing plates are respectively fixed to the front and rear outer walls of the resin drainage ditch. This design improves compressive strength while reducing weight and increasing load-bearing capacity. It also has the advantages of simple construction and convenient installation, making it more practical.

[0003] The aforementioned patents actually have the following problems in practice:

[0004] 1. When laying drainage ditches, it is often necessary to make turns according to road conditions or obstacles. Under the current technology, right-angle adapters or cutting and splicing the existing drainage ditch body are often used when making turns. This method is inconvenient during the laying process. Right-angle adapters have a single angle and poor adaptability, which cannot adapt to various situations. On the other hand, the cutting and splicing method is troublesome to operate and wastes time, which reduces the laying efficiency of drainage ditches.

[0005] 2. When laying drainage ditches at corners, the top cover often needs to be adjusted for the same compatibility. It also faces the problems of poor compatibility and the need for cutting, making it difficult to meet various different road conditions and obstacle avoidance needs. Summary of the Invention

[0006] The purpose of this invention is to provide a composite resin drainage ditch with a corner splicing structure and its assembly method, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a composite resin drainage ditch with a corner splicing structure, comprising a first drainage ditch body, a second drainage ditch body and a corner assembly, wherein the corner assembly is connected between the first drainage ditch body and the second drainage ditch body, and the two ends of the corner assembly are detachably inserted into the first drainage ditch body and the second drainage ditch body respectively.

The width of the top plate matches the width of the retaining frame, and the height of the retaining plates matches the depth of the retaining frame. The top plate is detachably snapped into the inside of the retaining frame by the retaining plates. Drain holes are provided on the top of the top plate, and the drain holes are arranged in an array at intervals.

[0010] Furthermore, the overall structure of the first drainage ditch is the same as that of the second drainage ditch.

[0011] Furthermore, the corner assembly includes a stretching channel, a splicing mechanism, and an adjusting top cover. Both ends of the stretching channel are provided with splicing mechanisms. The stretching channel is detachably inserted into the first and second insertion slots through the splicing mechanisms. The adjusting top cover is detachably disposed on the top of the stretching channel.

[0012] Furthermore, the stretching channel is made of a soft material, and the stretching channel as a whole is designed with a folded structure.

[0013] Furthermore, the splicing mechanism includes a first splicing joint, a second splicing joint, a connecting end, a flow guide wedge, a first insertion block, and a second insertion block. The first splicing joint and the second splicing joint are respectively disposed at both ends of the stretching channel. A connecting end is disposed on one side of the first splicing joint and is fixedly connected to one end of the stretching channel. A flow guide wedge is disposed on the other side of the first splicing joint. A first insertion block and a second insertion block are disposed on the outer side of the flow guide wedge. The size of the first insertion block matches the size of the first insertion slot, and the size of the second insertion block matches the size of the second insertion slot.

[0014] Furthermore, the overall structure of the first splice joint is the same as that of the second splice joint. The first splice joint and the second splice joint are respectively detachably snapped onto the first drainage ditch body and the second drainage ditch body through their first plug-in block and the second plug-in block.

[0015] Furthermore, the adjusting top cover includes an outer cover plate, an inner cover plate, a water inlet, an outer groove plate, an inner groove plate, an outer sliding plate, and an inner sliding plate. The outer cover plate and the inner cover plate are spaced apart, and the inner cover plate is located below the outer cover plate. Both the outer cover plate and the inner cover plate have water inlets on their tops. The number of outer cover plates is an even number of at least two, and the number of outer cover plates is one less than the number of inner cover plates. An outer groove plate is provided on the outer side of the outer cover plate, and an inner groove plate is provided on the inner side of the outer cover plate. An outer sliding plate is provided on the outer side of the inner cover plate, and an inner sliding plate is provided on the inner side of the inner cover plate.

[0016] Furthermore, the outer groove plate has a first sliding groove inside, and the outer slide plate has a first sliding tooth on its outer side. The first sliding tooth is slidably disposed inside the first sliding groove. The inner groove plate has a second sliding groove inside, and the inner slide plate has a second sliding tooth on its outer side. The second sliding tooth is slidably disposed inside the second sliding groove.

[0017] Another technical problem to be solved by the present invention is to provide a method for assembling a composite resin drainage ditch with a corner splicing structure, comprising the following steps:

[0018] Step 1: Lay out the drainage ditch and place the first and second drainage ditch bodies at both ends of the drainage ditch that needs to be connected at the corner;

[0019] Step 2: Place the corner assembly between the first and second drainage ditch bodies. Insert the first splice into the support frame of the first drainage ditch body through the first and second plug blocks. Stretch the stretching channel until the position of the second splice reaches the second drainage ditch body. Insert the second splice into the support frame of the second drainage ditch body through the first and second plug blocks.

[0020] Step 3: Place the adjusting top cover on top of the stretching channel, and pull the two outermost left and right outer slot plates of the adjusting top cover outward until the adjusting top cover is opened wide enough to cover the stretching channel, thus completing the assembly.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the existing technology, when laying drainage ditches, it is often necessary to make corners according to road conditions or obstacles. Current technologies often use right-angle adapters or directly cut and splice the existing drainage ditch body at corners, which is inconvenient during installation. Right-angle adapters have a limited angle and poor adaptability, failing to adapt to various situations. Cutting and splicing methods are cumbersome and time-consuming, reducing the efficiency of drainage ditch installation. This invention, however, allows for corner bending directly using a stretchable channel, eliminating the need for cutting and splicing. Various angles and lengths can be adjusted according to different road conditions and installation requirements, making corner treatment more flexible. It allows for curved obstacle avoidance or corner turns, improving splicing efficiency. The dual splicing design of the first and second splicing joints makes the splicing more stable and less prone to detachment.

[0023] 2. In the existing technology, when laying drainage ditches at corners, the top cover often needs to be adjusted for the same adaptability, which also faces the problems of poor adaptability and the need for cutting. It is difficult to meet various different road conditions and obstacle avoidance requirements. However, the sliding outer and inner cover plates of this invention allow the overall size of the adjustable top cover to be adjusted. Therefore, when laying drainage ditches in corner areas, the adaptability can be adjusted according to the actual laying length and angle, making the overall adaptability of the adjustable top cover stronger. It can meet various bending angles and lengths of drainage ditches, eliminating the need for cutting or splicing the top cover, improving assembly convenience and installation efficiency.

[0035] 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.

[0036] Please see Figure 1-3 A composite resin drainage ditch with a corner splicing structure includes a first drainage ditch body 1, a second drainage ditch body 2 and a corner component 3. The corner component 3 is connected between the first drainage ditch body 1 and the second drainage ditch body 2. The two ends of the corner component 3 are detachably inserted into the first drainage ditch body 1 and the second drainage ditch body 2, respectively.

[0037] The first drainage ditch body 1 includes a drainage ditch body 11 and a drain cover 12. The drain cover 12 is detachably snapped onto the top of the drainage ditch body 11. The drainage ditch body 11 includes a drainage channel 1101, a reinforcing plate 1102, a bottom plate 1103, a support frame 1104, a clip 1105, a first insertion slot 1106, and a second insertion slot 1107. The outer side of the drainage channel 1101 is surrounded by reinforcing plates 1102, which are arranged in an array at intervals. The bottom of the drainage channel 1101... The unit is provided with a base plate 1103, which is arranged crosswise with the reinforcing plate 1102. A bracket 1105 is provided on the top of the drainage channel 1101. The drain cover 12 is detachably clipped into the inside of the bracket 1105. Support frames 1104 are provided at both ends of the drainage channel 1101. A first insertion slot 1106 and a second insertion slot 1107 are provided inside the support frame 1104. One end of the corner component 3 is detachably inserted into the inside of the first insertion slot 1106 and the second insertion slot 1107.

[0038] Specifically, in use, the drainage ditch is first laid, and the first drainage ditch body 1 and the second drainage ditch body 2 are laid at both ends of the drainage ditch that needs to be connected at the corner. Then, the corner component 3 is placed between the first drainage ditch body 1 and the second drainage ditch body 2. One end of the corner component 3 is inserted into the inside of the first drainage ditch body 1, and the corner component 3 is stretched until its other end reaches the second drainage ditch body 2. The other end of the inner corner component 3 is then inserted into the inside of the second drainage ditch body 2, and the assembly is completed. This allows for easy adjustment of the bending angle of the drainage ditch corner, making it more adaptable.

[0039] The drain cover 12 includes a top plate 1201, drain holes 1202, and retaining plates 1203. Retaining plates 1203 are provided on both sides of the bottom surface of the top plate 1201. The width of the top plate 1201 matches the width of the retaining bracket 1105, and the height of the retaining plates 1203 matches the depth of the retaining bracket 1105. The top plate 1201 is detachably secured to the inside of the retaining bracket 1105 via the retaining plates 1203. Drain holes 1202 are provided on the top of the top plate 1201, and the drain holes 1202 are arranged in an array at intervals. The overall structure of the first drainage ditch 1 is the same as the overall structure of the second drainage ditch 2.

[0040] Specifically, during use, the drain cover 12 is snapped into the inside of the drainage ditch, and drainage is collected through the drain hole 1202.

[0041] To address the issue of corner turns often required during drainage ditch installation due to road conditions or obstacles, current technologies typically employ right-angle adapters or direct cutting and splicing of existing drainage ditch sections. These methods are inconvenient during installation. Right-angle adapters offer limited angles and poor adaptability, failing to accommodate various situations. Cutting and splicing methods are cumbersome and time-consuming, reducing the efficiency of drainage ditch installation. Please refer to [link to relevant documentation]. Figure 1 and Figure 3-5 The present invention provides the following technical solutions:

[0042] The corner assembly 3 includes a stretching channel 31, a splicing mechanism 32, and an adjustable top cover 33. Both ends of the stretching channel 31 are equipped with splicing mechanisms 32. The stretching channel 31 is detachably inserted into the first insertion slot 1106 and the second insertion slot 1107 via the splicing mechanisms 32. The adjustable top cover 33 is detachably mounted on the top of the stretching channel 31. The stretching channel 31 is made of a soft material and has an overall folded structure.

[0043] The splicing mechanism 32 includes a first splicing joint 3201, a second splicing joint 3202, a connecting end 3203, a guide vane 3204, a first insertion block 3205, and a second insertion block 3206. The first splicing joint 3201 and the second splicing joint 3202 are respectively disposed at both ends of the stretching channel 31. A connecting end 3203 is disposed on one side of the first splicing joint 3201 and is fixedly connected to one end of the stretching channel 31. A guide vane 3204 is disposed on the other side of the first splicing joint 3201. A first insertion block 3205 and a second insertion block 3206 are disposed on the outer side of the guide vane 3204. The size of the first insertion block 3205 matches the size of the first insertion groove 1106, and the size of the second insertion block 3206 matches the size of the second insertion groove 1107.

[0044] The overall structure of the first splice 3201 is the same as that of the second splice 3202. The first splice 3201 and the second splice 3202 are respectively detachably snapped onto the first drainage ditch body 1 and the second drainage ditch body 2 through their first plug-in block 3205 and the second plug-in block 3206.

[0045] Specifically, when splicing at the corners of the drainage ditch, the stretchable stretching channel 31 can be used directly to achieve the corner bend without cutting and splicing the drainage. Various angles and lengths of stretching can be adjusted according to different road conditions and installation requirements, making the treatment of the corners of the drainage ditch more flexible. It can be used for curved obstacle avoidance or corner turning, improving splicing efficiency. The double splicing joint setting of the first splicing joint 3201 and the second splicing joint 3202 makes the splicing more stable and less prone to falling off.

[0046] To address the issue that laying drainage ditches at corners often requires adjusting the top cover for similar compatibility, which also presents problems of poor compatibility and the need for cutting, making it difficult to meet the technical challenges of various road conditions and obstacle avoidance requirements, please refer to [link to relevant documentation]. Figure 6-10 The present invention provides the following technical solutions:

[0047] The adjustable top cover 33 includes an outer cover plate 3301, an inner cover plate 3302, a water inlet 3303, an outer groove plate 3304, an inner groove plate 3305, an outer sliding plate 3306, and an inner sliding plate 3307. The outer cover plate 3301 and the inner cover plate 3302 are spaced apart. The inner cover plate 3302 is located below the outer cover plate 3301. Both the outer cover plate 3301 and the inner cover plate 3302 have water inlets 3303 on their tops. The number of outer cover plates 3301 is an even number of at least two. The number of outer cover plates 3301 is one less than the number of inner cover plates 3302. The outer groove plate 3304 is located on the outer side of the outer cover plate 3301, and the inner groove plate 3305 is located on the inner side of the outer cover plate 3301. The outer sliding plate 3306 is located on the outer side of the inner cover plate 3302, and the inner sliding plate 3307 is located on the inner side of the inner cover plate 3302.

[0048] The outer groove plate 3304 has a first sliding groove 3308 inside, and the outer slide plate 3306 has a first sliding tooth 3309 on the outside. The first sliding tooth 3309 is slidably disposed inside the first sliding groove 3308. The inner groove plate 3305 has a second sliding groove 3310 inside, and the inner slide plate 3307 has a second sliding tooth 3311 on the outside. The second sliding tooth 3311 is slidably disposed inside the second sliding groove 3310.

[0049] Specifically, the sliding outer cover plate 3301 and inner cover plate 3302 allow the overall size of the adjustable top cover 33 to be adjusted. This enables the top cover to be adjusted according to the actual length and angle when laying the drainage ditch at corners, making it more adaptable and able to meet various bending angles and lengths of the drainage ditch. This eliminates the need for cutting or splicing the top cover, improving assembly convenience and installation efficiency.

[0050] To better demonstrate the composite resin drainage ditch with corner splicing structure, this embodiment proposes an assembly method for the composite resin drainage ditch with corner splicing structure, including the following steps:

[0051] Step 1: Lay out the drainage ditch and place the first drainage ditch body 1 and the second drainage ditch body 2 at both ends of the drainage ditch that needs to be connected at the corner;

[0052] Step 2: Place the corner assembly 3 between the first drainage ditch body 1 and the second drainage ditch body 2. Insert the first splice 3201 into the support frame 1104 of the first drainage ditch body 1 through the first plug block 3205 and the second plug block 3206. Stretch the stretching channel 31 until the position of the second splice 3202 reaches the second drainage ditch body 2. Insert the second splice 3202 into the support frame 1104 of the second drainage ditch body 2 through the first plug block 3205 and the second plug block 3206.

[0053] Step 3: Place the adjusting top cover 33 on top of the stretching channel 31, and pull the two outermost left and right outer groove plates 3304 of the adjusting top cover 33 outward until the adjusting top cover 33 is opened wide enough to cover the stretching degree of the stretching channel 31, thus completing the assembly.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
