Description

Technical Field

[0001] The utility model relates to the technical field of drainage ditches, in particular to a linear drainage ditch structure. Background Art

[0002] At present, the renovation and upgrading of existing squares and park green spaces are being carried out all over the country, and the requirements for infrastructure in large squares and park green spaces are getting higher and higher, from simple drainage functions to multiple requirements such as beauty, use, and economy. It is not only necessary to meet the interface drainage between green space and hard pavement, but also pay more attention to the emergency response ability of large squares to quickly drain water under sudden heavy rainfall, so as to promote the high-quality development of urban construction. Faced with many problems such as large squares with water accumulation and old facilities, existing technologies can solve some of the problems, but they need to be further improved in terms of comprehensiveness, integration, and ease of implementation;

[0003] The applicant has retrieved the prior art, (CN214784530U) discloses a HDPE linear drain ditch, the HDPE linear drain ditch comprises: a ditch body and a cover plate installed on the ditch body, the cover plate is provided with two leakage holes for water flow, the ditch body is provided with a drainage cavity for drainage; two filter blocks, each of the filter blocks comprises a plurality of equidistant and parallel separators, and the two ends of each separator are respectively fixedly connected to the inner walls on both sides of the leakage hole; two rotating mechanisms, each of the rotating mechanisms comprises a reciprocating screw rod installed transversely in the drainage cavity, and each of the rotating mechanisms is arranged below the leakage hole; two moving mechanisms, each of the moving mechanisms is installed on the reciprocating screw rod;

[0004] However, we can observe from the side view structure in the attached figure that a large number of linkage structures are set in the originally empty drainage trough structure, which greatly affects the drainage speed, and its structure is easy to get stuck, and the water flow fluctuation in the drainage ditch is not large. When the water flow speed is low, it is difficult to make it rotate;

[0005] Furthermore, it is not clear at all about the working principle of the reciprocating screw in the application, and it is not clear at all about how the sliding block moves back and forth when the rotating plate rotates in one direction. This is completely contrary to common sense and cannot be implemented at all. Utility Model Content

[0006] The technical problem to be solved by the utility model is: in order to overcome the above problems, a linear drainage ditch structure is provided, which solves the above problems.

[0007] The utility model solves the technical problem by adopting the following technical solutions:

[0008] A linear drainage ditch structure, comprising an integrated drainage ditch pre-buried in a road surface, used to collect rainwater and allow the rainwater to be discharged from high to low along the integrated drainage ditch into a municipal rainwater pipe;

[0009] A gutter grid cover is installed on the upper end cover of the integrated gutter. In order to facilitate the installation and improve the stability, stepped grooves are provided on both sides of the upper end of the integrated gutter. Both sides of the gutter grid cover are stuck in the stepped grooves. The gutter grid cover has a structural hole for rainwater to fall into the integrated gutter.

[0010] In order to avoid being blocked by leaves, an anti-blocking drainage float is also included, and float openings for inserting the anti-blocking drainage float are arranged at intervals on the gutter grid cover. The anti-blocking drainage float includes a hollow cap, a support rod, and a float, wherein the two ends of the support rod are respectively fixed to the hollow cap and the float, and the float is located in the integrated gutter. When rainwater enters the integrated gutter, the float floats and then the hollow cap is lifted up, so that a good drainage effect can be formed on the side and top surface of the hollow cap. When drainage is not needed, the anti-blocking drainage float automatically falls under the action of weight, and the upper end surface of the hollow cap is lower than the upper end surface of the gutter grid cover to reduce the chance of it being stepped on.

[0011] Preferably, in order to improve the floating effect of the anti-blocking drainage float, a water storage cylinder aligned with the float mouth is provided at intervals on the abdomen of the integrated drainage ditch. The water storage cylinder is open upward and is fixed to the integrated drainage ditch by welding, which is convenient for production and manufacturing. After raining, the water will first flow and concentrate in the water storage cylinder, so that there is enough water to float the anti-blocking drainage float. When the anti-blocking drainage float floats, the device has a horizontal drainage surface and a cylindrical drainage body, which can effectively avoid the clogging interference of leaves and ensure a good drainage effect.

[0012] Preferably, in order to limit the floating height of the anti-blocking drainage float and ensure that the anti-blocking drainage float can move up and down for a long time, a limiting brim is fixedly provided at the lower end of the hollow cap cover, and the diameter of the limiting brim is larger than the diameter of the float mouth, so that when the hollow cap cover floats up, it presses against the lower end surface of the drainage ditch grid cover to limit the position.

[0013] Preferably, drainage ditch U-shaped reinforcement ribs are provided at intervals on the outer side wall of the integrated drainage ditch, and the drainage ditch U-shaped reinforcement ribs are fixed to the integrated drainage ditch by welding, thereby effectively enhancing the structural strength of the integrated drainage ditch.

[0014] Preferably, reinforcing ribs are welded and fixed at intervals on the lower end surface of the gutter grid cover, and the reinforcing ribs can effectively enhance the structural strength of the gutter grid cover to prevent the buoy mouth from deforming and causing the anti-blocking drainage buoy to be unable to move up and down normally.

[0015] Preferably, when the anti-blocking drainage float is fully floated, the float is still completely in the water storage cylinder. The purpose of this design is to avoid the larger float lying across the water flow cross-section of the integrated drainage ditch to reduce the drainage speed of the water flow, while the smaller diameter of the support rod has little effect on the water flow speed of the integrated drainage ditch and does not affect actual needs.

[0016] The advantages and positive effects of the utility model are:

[0017] 1. By setting the anti-blocking drainage float 13, a raised drainage hollow structure is formed on the drainage ditch surface, so that water can be discharged smoothly.

[0018] 2. The water storage cylinder 17 can accumulate water at the early stage of rainwater accumulation to ensure that the anti-blocking drainage float 13 can be lifted up in the first time, thereby smoothly ensuring the subsequent drainage effect, and the water storage cylinder 17 can "hide" the float 21 to prevent it from lying across the drainage channel of the integrated drainage ditch 14 to reduce the flow rate of the water flow.

[0019] 3. In general, the device has a reasonable structural design and is easy to manufacture. Compared with the existing technology, it can achieve better anti-blocking effect and ensure smooth drainage. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0027] like Figure 1-3 As shown, a linear drainage ditch structure described in the utility model includes an integrated drainage ditch 14 pre-buried in the road surface, which is used to collect rainwater and allow the rainwater to be discharged from high to low along the integrated drainage ditch 14 into the municipal rainwater pipe;

[0028] A gutter grid cover 10 is installed on the upper end cover of the integrated gutter 14. In order to facilitate the installation and improve the stability, stepped grooves 15 are provided on both sides of the upper end of the integrated gutter 14. Both sides of the gutter grid cover 10 are stuck in the stepped grooves 15. The gutter grid cover 10 has a structural hole for rainwater to fall into the integrated gutter 14.

[0029] In order to avoid being blocked by leaves, an anti-blocking drainage float 13 is also included, and float ports 11 for inserting the anti-blocking drainage float 13 are arranged at intervals on the gutter grid cover 10. The anti-blocking drainage float 13 includes a hollow cap 18, a support rod 20, and a float 21, wherein the two ends of the support rod 20 are respectively fixed to the hollow cap 18 and the float 21, and the float 21 is located in the integrated gutter 14. When rainwater enters the integrated gutter 14, the float 21 floats and then the hollow cap 18 is lifted up, so that a good drainage effect can be formed on the side and top surface of the hollow cap 18. When drainage is not needed, the anti-blocking drainage float 13 automatically falls under the action of weight, and the upper end surface of the hollow cap 18 is lower than the upper end surface of the gutter grid cover 10 to reduce the chance of it being stepped on.

[0030] Preferably, in order to improve the floating effect of the anti-blocking drainage float 13, a water storage cylinder 17 aligned with the float mouth 11 is provided at intervals on the abdomen of the integrated drainage ditch 14. The water storage cylinder 17 is open upward and fixed to the integrated drainage ditch 14 by welding, which is convenient for production and manufacturing. After raining, the water will first flow and concentrate in the water storage cylinder 17, so that there is enough water to float the anti-blocking drainage float 13. When the anti-blocking drainage float 13 floats, the device has a horizontal drainage surface and a cylindrical drainage body, which can effectively avoid the clogging interference of leaves and ensure a good drainage effect.

[0031] Preferably, in order to limit the floating height of the anti-blocking drainage float 13 and ensure that the anti-blocking drainage float 13 can permanently telescope up and down, a limiting brim 19 is fixedly provided at the lower end of the hollow cap 18, and the diameter of the limiting brim 19 is larger than the diameter of the float mouth 11, so that when the hollow cap 18 floats up, it presses against the lower end surface of the drainage ditch grid cover 10 for limitation.

[0032] Preferably, drainage ditch U-shaped reinforcement ribs 16 are also provided at intervals on the outer side wall of the integrated drainage ditch 14 . The drainage ditch U-shaped reinforcement ribs 16 are fixed to the integrated drainage ditch 14 by welding, thereby effectively enhancing the structural strength of the integrated drainage ditch 14 .

[0033] Preferably, reinforcing ribs 12 are welded and fixed at intervals on the lower end surface of the gutter grid cover 10, and the reinforcing ribs 12 can effectively enhance the structural strength of the gutter grid cover 10, thereby preventing the buoy mouth 11 from deforming and causing the anti-blocking drainage buoy 13 to be unable to move up and down normally.

[0034] Preferably, when the anti-blocking drainage float 13 is fully floated, the float 21 is still completely in the water storage cylinder 17. The purpose of this design is to avoid the larger float 21 lying across the water flow cross-section of the integrated drainage ditch 14 to reduce the drainage speed of the water flow, while the smaller diameter of the support rod 20 has little effect on the water flow speed of the integrated drainage ditch 14 and does not affect actual needs.

[0035] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
