Description

Technical Field

[0001] This utility model belongs to the field of drainage structure technology, and specifically relates to a drainage structure for garden landscapes. Background Technology

[0002] Landscape drainage ditches are not only fast channels for urban drainage, but also commonly used walkway drainage structures in garden design. Through their good drainage capacity, garden walkways can drain water quickly in rainy weather, thereby preventing rainwater from accumulating on the walkways and affecting pedestrians.

[0003] Existing landscape drainage ditches are typically composed of drainage channels and covers with drainage holes. Rainwater flows into the drainage channel through the drainage holes on the cover due to the slope of the ground. However, various kinds of garbage, impurities, leaves, etc. may exist on the ground. These impurities have poor mobility and will accumulate and mold in the drainage channel after flowing into it during heavy rainfall, thus accelerating the damage to the drainage channel and potentially causing blockages. Furthermore, existing drainage ditches are usually made of concrete, making subsequent maintenance and cleaning cumbersome and unsuitable for practical use. Utility Model Content

[0004] The present invention aims to provide a drainage structure for garden landscapes to solve the problem of the cumbersome maintenance and cleaning of existing drainage ditches mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a garden landscape drainage structure, installed within a drainage ditch, comprising...

[0006] The drain pipe has protrusions at both ends and slides into the drainage ditch. The cross-section of both the drain pipe and the protrusions is an inverted "Ω" shape, and a limit hole is provided at the top of the protrusion.

[0007] The connecting pipe has an inverted "Ω" shaped cross-section. The connecting pipe slides into the drainage ditch. Grooves are provided on both sides of the connecting pipe, and the protrusions are adapted to the grooves. The connecting pipe abuts against the drainage pipe. The inner and outer surfaces of the connecting pipe are flush with the inner and outer surfaces of the drainage pipe, respectively.

[0008] The connecting bolt is threaded into the connecting pipe, and the end of the connecting bolt is slidably inserted into the limiting hole;

[0009] The support unit is installed in the drainage ditch and is used to support the drainage pipe.

[0010] The principle and effects of this technical solution:

[0011] 1. By installing drain pipes and connecting pipes inside the drainage ditch, garbage and impurities will not come into direct contact with the drainage ditch. Instead, they will accumulate on the drain pipes or connecting pipes, allowing for easy replacement if they are damaged. This method is more cost-effective and convenient, while also protecting the drainage ditch. Furthermore, the accumulated impurities can be removed during cleaning, making subsequent cleaning and maintenance more convenient.

[0012] 2. The connecting pipe and the drain pipe are connected by connecting bolts, which allows the connecting pipe and the drain pipe to be assembled or disassembled, thus facilitating subsequent replacement and maintenance, as well as extending the length. Furthermore, the protrusion fits into the groove, and the inner and outer walls of the drain pipe and the connecting pipe are flush. As a result, the flat joint of the connecting pipe and the drain pipe is blocked by the protrusion, making it difficult for water to seep into the bottom of the drainage ditch from the flat joint.

[0013] 3. The drainage pipe and connecting pipe can be raised by setting up the support unit.

[0014] The present invention is further configured such that: the support unit includes two fixing frames respectively disposed at both ends of the drainage ditch, and a first fixing rod and a second fixing rod are respectively fixed inside the two fixing frames. The first fixing rod and the second fixing rod have different horizontal heights, and the first fixing rod and the second fixing rod respectively abut against the bottom edge of the drainage pipe. A sliding groove is provided on the top of the side wall of the fixing frame, and a rotating shaft is fitted in the sliding groove. The rotating shaft is fixed on the outer wall of the drainage pipe, and the lower end of the drainage pipe can move inside the fixing frame.

[0015] The principle and effect of this technical solution: By setting the rotating shaft in the slide groove, the fixed frame can restrict the position of the connecting pipe, that is, the connecting pipe can only move up and down or rotate along the fixed frame, but cannot move horizontally. By setting the first fixed rod and the second fixed rod at different heights, the pipes connected to the multiple connecting pipes and the drain pipe are arranged at an angle, thereby improving the flow of water in the drain pipe and the connecting pipe.

[0016] The present invention is further configured such that: the support unit also includes several support frames spaced apart between the two fixed frames, a support rod is movably installed inside the support frame, and an elastic component is also installed inside the support frame. The elastic component is used to drive the support rod to approach the drain pipe. The support rod abuts against the bottom edge of the drain pipe. The lower end of the drain pipe can move inside the support frame. The top edge of the support rod is located between the top edge of the first fixed rod and the top edge of the second fixed rod. A sliding groove is also provided on the top of the side wall of the support frame.

[0017] The principle and effect of this technical solution: By setting up the support frame and support rod, the middle part of the combination of long drainage pipe and connecting pipe can be supported by the support frame, support rod and elastic component, thereby making the supporting force on the device more uniform and avoiding the collapse of the middle part of the device.

[0018] The present invention is further configured such that: a clearance groove is provided on the side wall of the support frame, a guide rod is fixed in the clearance groove, and sliders are fixed at both ends of the support rod respectively. The sliders slide in cooperation with the clearance groove, and the sliders are slidably mounted on the guide rod. A spring is mounted on the guide rod, and the top edge of the spring abuts against the bottom edge of the slider.

[0019] The principle and effect of this technical solution: The spring's rebound force drives the slider to move upward, which in turn causes the slider to tend to move the support rod closer to the drain pipe. When the drain pipe presses down on the support rod, it will be subjected to the spring's rebound force, thus providing support for the drain pipe. Depending on the length of the drain pipe, the slope is different, that is, the bottom edge height of the drain pipe is different at different locations. The spring can spontaneously adapt, resulting in a better fit.

[0020] The present invention is further configured such that: the top of the drainage ditch is stepped, and a limiting post is fixed inside the drainage ditch; a cover plate is hung on the drainage ditch, and the cover plate is slidably fitted onto the limiting post.

[0021] The principle and effect of this technical solution: Through the stepped design, the cover plate can be hung on the drainage ditch, and the limiting post can limit the position of the cover plate, preventing the drainage ditch from being misaligned due to pedestrians stepping on it.

[0022] The present invention is further provided that a filter screen is detachably installed inside the connecting pipe.

[0023] The principle and effect of this technical solution: The filter screen can intercept garbage and impurities in stages, thereby preventing garbage and impurities from accumulating and clogging in one place under the influence of water flow.

[0024] The present invention is further configured such that the slope of the drainage pipe does not exceed 5°.

[0025] The principle and effect of this technical solution: By limiting the slope of the drainage pipe, the maximum height difference between the two ends of the drainage pipe is limited. An excessively small height difference is not conducive to the movement of impurities, and does not hinder the movement of water flow. Attached Figure Description

[0039] Example:

[0040] As attached Figure 1-6 As shown, this utility model discloses a garden landscape drainage structure, installed in a drainage ditch 110, including a drainage pipe 210, a connecting pipe 310, a connecting bolt 410, and a support unit. The drainage pipe 210 has protrusions 220 at both ends, and the drainage pipe 210 slides into the drainage ditch 110. Both the drainage pipe 210 and the protrusions 220 have inverted "Ω" shaped cross sections. A limiting hole 221 is provided at the top of the protrusions 220. The connecting pipe 310 has an inverted cross section... The "Ω" shape of the connecting pipe 310 is slidably fitted with the drainage ditch 110. Grooves 311 are respectively provided on both sides of the connecting pipe 310. The protrusion 220 is adapted to the groove 311. The connecting pipe 310 abuts against the drainage pipe 210. The inner and outer surfaces of the connecting pipe 310 are flush with the inner and outer surfaces of the drainage pipe 210, respectively. The connecting bolt 410 is threaded into the connecting pipe 310, and the end of the connecting bolt 410 is slidably inserted into the limiting hole 221.

[0041] The top of the drainage ditch 110 is stepped, and a limiting post 111 is fixed inside the drainage ditch 110. A cover plate 120 is hung on the drainage ditch 110, and the cover plate 120 is slidably fitted onto the limiting post 111.

[0042] Multiple connecting pipes 310 and drain pipes 210 are provided and connected end to end by connecting bolts 410. A filter screen 320 is detachably installed inside the connecting pipe 310. The connecting pipe 310 and drain pipe 210 as a whole can slide or rotate relative to the drainage ditch 110.

[0043] The support unit includes two fixing frames 510 respectively located at both ends of the drainage ditch 110. A first fixing rod 520 and a second fixing rod 530 are respectively fixed inside the two fixing frames 510. The first fixing rod 520 and the second fixing rod 530 have different horizontal heights, and the first fixing rod 520 and the second fixing rod 530 respectively abut against the bottom edge of the drainage pipe 210. A sliding groove 540 is opened on the top of the side wall of the fixing frame 510. A rotating shaft 230 is fitted in the sliding groove 540. The rotating shaft 230 is fixed on the outer wall of the drainage pipe 210. The lower end of the drainage pipe 210 can move inside the fixing frame 510.

[0044] The support unit also includes several support frames 550 spaced apart between the two fixed frames 510. Support rods 560 are movably installed inside the support frame 550, and an elastic component is also installed inside the support frame 550. The elastic component is used to drive the support rods 560 closer to the drain pipe 210. The support rods 560 abut against the bottom edge of the drain pipe 210. The lower end of the drain pipe 210 can move inside the support frame 550. The top edge of the support rods 560 is located between the top edge of the first fixed rod 520 and the top edge of the second fixed rod 530. A sliding groove 540 is also provided on the top of the side wall of the support frame 550.

[0045] The support frame 550 has a clearance groove 551 on its side wall. A guide rod 552 is fixed in the clearance groove 551. Slider blocks 580 are fixed at both ends of the support rod 560. The sliders 580 slide in the clearance groove 551 and are slidably mounted on the guide rod 552. A spring 570 is mounted on the guide rod 552. The top edge of the spring 570 abuts against the bottom edge of the slider 580. The maximum elastic force provided by each spring 570 is less than the sum of the weights of its corresponding drain pipe 210 and connecting pipe 310. It mainly plays an auxiliary support role. The excess weight can be transferred to the drain pipes 210 at both ends through the cooperation between the protrusion 220 and the groove 311.

[0046] Among them, the two fixed frames 510 are connected to the drainage pipes 210 located at both ends, which serves to fix the slope. The remaining support frames 550 and support rods 560 located between the two fixed frames 510 provide auxiliary support. The slope of the drainage pipes 210 does not exceed 5°.

[0047] In actual use, if the drainage ditch 110 itself has a certain slope, the drainage pipe 210 and connecting pipe 310 can be placed directly in the drainage ditch 110 as a whole, and different fixing brackets 510 can be replaced to make different tilt angles.

[0048] Among them, components such as spring 570 and connecting bolt 410 have undergone rust prevention treatment (such as rust-proof coating) to prevent them from rusting due to long-term exposure to a humid environment, which would affect the normal use of the structure.

[0049] Among them, insert and sliding insert are mating bodies with holes, the cross section of the shaft or rod matches the hole, and the shaft or rod can slide relative to the hole. Threaded insert is a hole with threads, the shaft or rod is threaded, and the shaft or rod is connected to the mating body by screwing. Detachable installation can be by bolt thread connection or bolt and nut connection, etc., depending on what can be actually achieved.
