Description

Technical Field

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

[0002] Drainage ditches are a common municipal facility used for highway drainage, typically installed on both sides of a highway. Drainage ditches direct water collected from side ditches, intercepting ditches, and low-lying areas near roadbeds, crop fields, and residential areas to areas away from these areas. However, existing drainage ditches often contain debris such as garbage, leaves, and sediment, along with surface water and rainfall. Due to their limited cross-sectional area, these ditches can become clogged over time, making drainage difficult.

[0003] For example, in the patent announcement number CN215211422U, named "Drainage Ditch Structure", the drainage ditch structure includes a drainage ditch and a trash net; the trash net is installed in the drainage ditch to intercept debris flowing with the liquid in the drainage ditch; the bottom of the drainage ditch is provided with a downwardly concave receiving groove, and the receiving groove is located on the upstream side of the trash net. The drainage ditch structure of the utility model can intercept debris through the trash net, and then the debris can fall into the receiving groove on the upstream side of the trash net under the action of its own weight, thereby preventing debris from clogging the drainage ditch and alleviating the difficulty of drainage. The disadvantage is that the drainage ditch structure has only one place for drainage, low efficiency, and cannot drain water when blocked. Utility Model Content

[0004] In view of the shortcomings of the existing drainage ditch structure that there is only one place for drainage, low efficiency, and inability to drain water when blocked, the purpose of this utility model is to provide a sloped drainage ditch that effectively intercepts dirt through a sewage net, optimizes water flow distribution, and ensures smooth drainage, thereby improving drainage efficiency, reducing the risk of drainage ditch blockage, and ensuring the long-term stable operation of the drainage ditch.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a sloped drainage ditch, comprising a drainage ditch and a trash net for intercepting dirt, the trash net being installed on the upper surface of the drainage ditch, a plurality of receiving grooves being provided at the bottom of the drainage ditch, through openings being provided between the plurality of receiving grooves, the heights of the plurality of receiving grooves gradually increasing along the water flow direction of the drainage ditch, and a drainage outlet being provided at the bottom of the plurality of receiving grooves.

[0006] In this technical solution, the trash net installed on the upper surface of the drain ditch can successfully intercept large wastes and prevent them from entering the interior of the drain ditch, thereby keeping the drain clean and unobstructed. The bottom of the drain ditch is designed with multiple receiving grooves, and the height of these receiving grooves gradually increases along the direction of water flow in the drain ditch, which helps to divert and slow down the water flow speed step by step according to the water flow speed and water volume. It can not only reduce the impact of the water flow on the drain ditch, but also improve the drainage efficiency. A drain outlet is provided at the bottom of the receiving groove, which can ensure that the water in the receiving groove is discharged smoothly, avoid water accumulation, and further ensure the drainage capacity of the drain ditch. The multiple drain outlets provided at the bottom of the drain ditch significantly increase the water outlet points of the drainage system, so that the water flow can be discharged more quickly and evenly, effectively avoiding water accumulation and improving the overall drainage efficiency. The multiple drain outlets enable this slope drain ditch to better adapt to different rainfall intensities and terrain conditions, and can maintain efficient drainage performance regardless of heavy rain or continuous light rain.

[0007] The present invention further features a closed structure at both ends of the gutter's length. This design effectively prevents debris, garbage, and unwanted water from entering the gutter, significantly reducing the risk of gutter blockage. This closed structure also enhances the gutter's overall structural stability, improving its durability and service life.

[0008] The present invention is further configured as follows: among the multiple receiving tanks, the receiving tank with the largest height is the first receiving tank, and the bottom of the first receiving tank is provided with two drain outlets. As the tank body with the largest height, the first receiving tank can accommodate more water flow. By adding two drain outlets at its bottom, the water discharge speed can be accelerated, effectively preventing water accumulation, thereby greatly improving the overall drainage capacity of the drainage ditch. The design of the receiving tank with gradually increasing height itself helps to divert water step by step according to the water flow speed and water volume, and the design of the double drain outlet of the first receiving tank further optimizes the distribution and discharge of water flow, ensuring that the water flow can pass through the drainage ditch quickly and smoothly. Since the drainage efficiency of the first receiving tank is improved, the water flow speed in the entire drainage ditch will also be accelerated accordingly, which helps to reduce the accumulation of debris and garbage, thereby reducing the risk of the drainage ditch being blocked.

[0009] The present invention is further configured such that the width of the plurality of receiving grooves gradually increases along the length direction of the drainage ditch. As the width of the receiving grooves gradually increases, the amount of water that each groove body can accommodate also increases. This is particularly important for handling water flows in large flows or under heavy rain conditions, and can effectively prevent water from overflowing the drainage ditch and keep the road surface or slope dry. The design of the receiving grooves with gradually increasing width helps the water flow more smoothly in the drainage ditch. The wider groove body can reduce the obstruction of the water flow and reduce the change in the water flow speed, thereby reducing the scouring and wear of the groove wall by the water flow and extending the service life of the drainage ditch. The design of the receiving grooves with gradually increasing width also helps to enhance the structural stability of the drainage ditch. The wider groove body can provide better support and reduce structural deformation or damage caused by water flow impact or external pressure.

[0010] The present invention is further provided with a support frame between the plurality of receiving troughs. The addition of the support frame significantly enhances the overall structural strength of the drainage ditch. As an important component for connecting and supporting each receiving trough, the frame can withstand greater water flow impact and external pressure, and prevent the drainage ditch from being deformed or damaged due to uneven force. In a sloped drainage ditch, the trough body may be subjected to forces in different directions due to the influence of terrain and gravity. The presence of the support frame can effectively fix and support the receiving trough, preventing displacement or tilting due to water erosion or external factors, thereby maintaining the stability of the trough body. The design of the support frame also takes into account the convenience of installation and maintenance. Through the connection of the frame, the various receiving troughs can be more easily assembled together to form a complete drainage ditch system. At the same time, when the trough body needs to be repaired or replaced, the frame also provides convenient support and fixing points, reducing the difficulty and cost of maintenance.

[0011] The present invention is further configured such that the accommodating space of the plurality of accommodating grooves gradually increases along the direction of water flow in the drainage ditch. As the direction of water flow in the drainage ditch extends, the water flow will gradually converge and increase the flow rate. The design of the gradually increasing accommodating space can well adapt to this change in water flow, ensuring that water flow can be effectively accommodated and discharged at any position in the drainage ditch to avoid water overflow or blockage. The gradually increasing accommodating space enables each accommodating groove to more effectively utilize its volume to process and discharge water flow. It helps to speed up the water flow speed and reduce the residence time of water flow in the drainage ditch, thereby improving the overall drainage efficiency. The gradually increasing accommodating space design also helps to enhance the structural stability of the drainage ditch, because the larger accommodating groove can provide better support and fixing points, making the entire drainage ditch more stable and reliable when dealing with water flow impact and external pressure.

[0012] The present invention is further configured as follows: an opening is provided at the top of the drainage ditch, and a collection container is provided in the receiving tank. The design of the top opening allows water to easily enter the drainage ditch without the need for additional guiding or intercepting facilities, which helps to ensure that when rain or water flow occurs, water can flow quickly and smoothly into the drainage ditch, reducing water accumulation. Providing a collection container in the receiving tank can more effectively collect and store water flow, and can centrally capture and temporarily store water flow, reducing water loss and waste, thereby improving the collection and utilization efficiency of water resources. The opening design and the collection container in the receiving tank make cleaning and maintenance of the drainage ditch more convenient. Workers can directly enter the drainage ditch to clean and replace the collection container without dismantling or destroying the structure of the drainage ditch.

[0013] The present invention is further configured as follows: the surface of the trash net is provided with a water inlet and a friction structure. The water inlet design on the surface of the trash net ensures that the water flow can smoothly pass through the trash net into the drain ditch without being excessively obstructed by the net body itself. It helps to maintain the continuity of the water flow and reduce the flow rate slowdown or water accumulation caused by the trash net. The setting of the friction structure enhances the contact between the surface of the trash net and impurities in the water flow, thereby improving the efficiency of impurities being captured and retained, helping to reduce impurities entering the downstream drain ditch with the water flow, and keeping the drain clean and unobstructed. Since the friction structure enhances the trash net's ability to intercept pollution, it can reduce the risk of drain ditch blockage caused by impurity accumulation, thereby reducing the maintenance frequency and cost of the drain and extending its service life. The friction structure not only improves the trash net's ability to intercept pollution, but also helps to enhance the structural stability of the net body. By increasing the roughness of the net body surface, the friction structure improves the net body's resistance to water flow impact and reduces damage or deformation of the net body caused by water scouring.

[0014] The advantages of the present invention are: (1) the trash net effectively intercepts large-scale waste, optimizes water flow distribution, and ensures smooth drainage, thereby improving drainage efficiency, reducing the risk of gutter blockage, and ensuring the long-term stable operation of the gutter; (2) the trash net installed on the upper surface of the gutter can successfully intercept large-scale waste and prevent it from entering the gutter, thereby keeping the gutter clean and unobstructed. The gutter bottom is designed with multiple receiving grooves, and the height of these receiving grooves gradually increases along the direction of water flow in the gutter, which helps to divert and slow down the water flow speed step by step according to the water flow speed and water volume. It can not only reduce the impact of water flow on the gutter, but also improve drainage efficiency. The bottom of the receiving groove is provided with a drain port, which can ensure that the water in the receiving groove is discharged smoothly, avoid water accumulation, and further ensure the drainage capacity of the gutter.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1:

[0023] Reference Figures 1 to 4 A slope drainage ditch includes a drainage ditch 1 and a trash net 2 for intercepting dirt. The trash net 2 is installed on the upper surface of the drainage ditch 1. A plurality of receiving grooves 11 are provided at the bottom of the drainage ditch 1. Through openings are provided between the plurality of receiving grooves 11. The heights of the plurality of receiving grooves 11 gradually increase along the water flow direction of the drainage ditch 1. A drainage outlet 12 is provided at the bottom of the plurality of receiving grooves 11.

[0024] In this embodiment, the trash screen 2 installed on the upper surface of the gutter 1 can successfully intercept large pieces of waste and prevent them from entering the gutter 1, thereby keeping the gutter 1 clean and unobstructed. Multiple receiving grooves 11 are designed at the bottom of the gutter 1, and the height of these receiving grooves 11 gradually increases along the direction of water flow in the gutter 1. This helps to gradually divert and slow the water flow according to the speed and amount of water. This not only reduces the impact of the water flow on the gutter 1, but also improves drainage efficiency. Drain outlets 12 are provided at the bottom of the receiving grooves 11 to ensure that the water in the receiving grooves 11 can be discharged smoothly, preventing water accumulation and further ensuring the drainage capacity of the gutter 1. The multiple drain outlets 12 at the bottom of the gutter significantly increase the number of water outlets in the drainage system, allowing water to be discharged more quickly and evenly, effectively preventing water accumulation and improving overall drainage efficiency. The design of multiple drain outlets 12 allows this sloped gutter to better adapt to different rainfall intensities and terrain conditions, maintaining efficient drainage performance whether in heavy rain or continuous light rain.

[0025] It can be understood that the trash net 2 and the drain ditch 1 are detachably connected to facilitate daily maintenance and cleaning.

[0026] It can be understood that the trash net 2 and the drain ditch 1 are connected by bolts, snaps or pins.

[0027] As will be appreciated, the drain ditch 1 is enclosed at both ends along its length. The sloped drain ditch's design employs a closed structure at both ends, effectively preventing debris, garbage, and unnecessary water from entering through both ends of the drain ditch 1, thereby significantly reducing the risk of clogging. This closed structure also enhances the overall structural stability of the drain ditch 1, improving its durability and service life.

[0028] refer to Figure 1 、 Figure 3 Among the multiple receiving tanks 11, the receiving tank 11 with the largest height is the first receiving tank 13, and two drain outlets 12 are provided at the bottom of the first receiving tank 13. As the tank body with the largest height, the first receiving tank 13 can accommodate more water flow. By adding two drain outlets 12 at its bottom, the water discharge speed can be accelerated, and water accumulation can be effectively prevented, thereby greatly improving the overall drainage capacity of the drainage ditch 1. The design of the receiving tank 11 with gradually increasing height itself helps to divert water step by step according to the water flow speed and water volume, and the design of the double drain outlets 12 of the first receiving tank 13 further optimizes the distribution and discharge of water flow, ensuring that the water flow can pass through the drainage ditch 1 quickly and smoothly. Since the drainage efficiency of the first receiving tank 13 is improved, the water flow speed in the entire drainage ditch 1 will also be accelerated accordingly, which helps to reduce the accumulation of debris and garbage, thereby reducing the risk of the drainage ditch 1 being blocked.

[0029] The width of the multiple receiving grooves 11 along the length direction of the drainage ditch 1 gradually increases. As the width of the receiving grooves 11 gradually increases, the water flow that each groove body can accommodate also increases. This is especially important for handling water flows in large flows or rainstorms, and can effectively prevent water from overflowing the drainage ditch 1 and keep the road surface or slope dry. The design of the receiving grooves 11 with gradually increasing width helps the water flow more smoothly in the drainage ditch 1. The wider groove body can reduce the obstruction of water flow and reduce the change in water flow speed, thereby reducing the scouring and wear of the groove wall by the water flow and extending the service life of the drainage ditch 1. The design of the receiving grooves 11 with gradually increasing width also helps to enhance the structural stability of the drainage ditch 1. The wider groove body can provide better support and reduce structural deformation or damage caused by water flow impact or external pressure.

[0030] Preferably, a support frame 14 is provided between the plurality of receiving troughs 11. The addition of the support frame 14 significantly enhances the overall structural strength of the drainage ditch 1. As an important component for connecting and supporting each receiving trough 11, the frame can withstand greater water flow impact and external pressure, and prevent the drainage ditch 1 from being deformed or damaged due to uneven force. In a sloped drainage ditch, the trough body may be subjected to forces in different directions due to the influence of terrain and gravity. The presence of the support frame 14 can effectively fix and support the receiving trough 11, preventing displacement or tilting due to water erosion or external factors, thereby maintaining the stability of the trough body. The design of the support frame 14 also takes into account the convenience of installation and maintenance. Through the connection of the frame, the various receiving troughs 11 can be more easily assembled together to form a complete drainage ditch 1 system. At the same time, when the trough body needs to be repaired or replaced, the frame also provides convenient support and fixing points, reducing the difficulty and cost of maintenance.

[0031] Preferably, the accommodation space of the plurality of said accommodation grooves 11 gradually increases along the direction of water flow in the drain ditch 1. As the direction of water flow in the drain ditch 1 extends, the water flow will gradually converge and increase the flow rate. The design of gradually increasing accommodation space can well adapt to this change in water flow, ensuring that water flow can be effectively accommodated and discharged at any position in the drain ditch 1 to avoid water overflow or blockage. The gradually increasing accommodation space enables each accommodation groove 11 to more effectively utilize its volume to process and discharge water flow. It helps to speed up the water flow speed and reduce the residence time of water flow in the drain ditch 1, thereby improving the overall drainage efficiency. The gradually increasing accommodation space design also helps to enhance the structural stability of the drain ditch 1, because the larger accommodation groove 11 can provide better support and fixing points, making the entire drain ditch 1 more stable and reliable when dealing with water flow impact and external pressure.

[0032] refer to Figure 1 、 Figure 2, the top of the drainage ditch 1 is provided with an opening, and the receiving tank 11 is provided with a collecting container. The design of the top opening allows water to easily enter the drainage ditch 1 without the need for additional guiding or intercepting facilities, which helps to ensure that when rain or water flow occurs, water can flow quickly and smoothly into the drainage ditch 1, reducing water accumulation. Providing a collecting container in the receiving tank 11 can more effectively collect and store water flow, and can centrally capture and temporarily store water flow, reduce water loss and waste, and thus improve the collection and utilization efficiency of water resources. The opening design and the collecting container in the receiving tank 11 make the cleaning and maintenance of the drainage ditch 1 more convenient. The staff can directly enter the drainage ditch 1 to clean and replace the collecting container without dismantling or destroying the structure of the drainage ditch 1.

[0033] Example 2:

[0034] refer to Figure 2 , the surface of the trash net 2 is provided with a water inlet 21 and a friction structure 22. The design of the water inlet 21 on the surface of the trash net 2 ensures that the water flow can smoothly pass through the trash net 2 into the drain ditch 1 without being excessively obstructed by the net body itself. It helps to maintain the continuity of the water flow and reduce the flow rate slowdown or water accumulation caused by the trash net 2. The setting of the friction structure 22 enhances the contact between the surface of the trash net 2 and impurities in the water flow, thereby improving the efficiency of impurities being captured and retained, helping to reduce impurities entering the downstream of the drain ditch 1 with the water flow, and keeping the drain ditch 1 clean and unobstructed. Since the friction structure 22 enhances the pollution interception ability of the trash net 2, it can reduce the risk of clogging of the drain ditch 1 due to the accumulation of impurities, thereby reducing the maintenance frequency and cost of the drain ditch 1 and extending its service life. The friction structure 22 not only improves the trash-blocking effect of the trash-blocking net 2, but also helps to enhance the structural stability of the net. By increasing the roughness of the net surface, the friction structure 22 improves the net's resistance to water flow impact and reduces damage or deformation of the net caused by water erosion.

[0035] It can be understood that the friction structure 22 is a raised texture, a hook-shaped structure or a mesh-like interwoven structure.

[0036] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
