Technical Field
[0001] This utility model relates to the field of highway drainage facilities technology, specifically to a press-type drainage ditch. Background Technology
[0002] In modern urban drainage systems, drainage ditch covers are an indispensable and important component. Their main function is to cover the drainage ditches, ensure the structural stability of the drainage ditches, and allow rainwater to flow into them. Traditional drainage ditch covers are usually designed to be fixed. Although they can achieve basic functions of coverage and structural stability, they have obvious defects in long-term use.
[0003] Traditional fixed drainage ditch covers are prone to accumulating debris such as leaves, plastic bags, and mud at their surfaces and outlets, hindering rainwater drainage and causing poor flow. In the event of heavy rainfall, this can even lead to a complete blockage of the drainage system, causing road flooding, affecting traffic safety, and greatly inconveniencing urban residents. More importantly, when traditional covers become clogged, maintenance personnel must manually clean them. This process involves lifting the cover or operating within its confined space, which is not only cumbersome and time-consuming but also inefficient, temporarily disrupting the drainage system and preventing timely restoration of smooth flow.
[0004] Therefore, in order to address the problems of traditional drainage ditch covers being prone to clogging, difficult to clean, and affecting drainage efficiency, a new type of drainage ditch structure is urgently needed to solve the above-mentioned drawbacks. Utility Model Content

A cover plate body is installed above the cover plate support platforms. Spring telescopic toothed columns are provided between the four corners of the cover plate body and the cover plate support platforms. A compression spring is provided at the lower end of the spring telescopic toothed column. The spring telescopic toothed column is configured to move downward under pressure to apply pressure to the compression spring, thereby compressing the compression spring. The spring telescopic toothed column locks the cover plate body in an extended position and a retracted position by means of the rebound force of the compression spring.
[0008] When the cover plate body is in the extended position, the bottom surface of the cover plate body is higher than the top surface of the channel body; when the cover plate body is in the retracted position, the top surface of the cover plate body is flush with the top surface of the channel body.
[0009] As a preferred embodiment of this utility model, the spring telescopic toothed column includes a fixed sleeve with an upper opening and a pressing member, a locking member, a cam rotating member, and a compression spring arranged sequentially from top to bottom inside the fixed sleeve. The lower end of the pressing member passes through the interior of the locking member and abuts against the upper end of the cam rotating member. The upper end of the pressing member passes through the upper opening of the fixed sleeve and connects to the cover plate body. The upper and lower ends of the compression spring abut against the bottom of the cam rotating member and the bottom plate of the fixed sleeve, respectively.
[0010] The pressing element is configured to move within the locking element along the length of the locking element and apply pressure to the cam rotating element;
[0011] The cam rotator is configured to lock the cover body in the extended position when in a first engaged state with the locking member, and to lock the cover body in the retracted position when in a second engaged state with the locking member.
[0012] As a preferred embodiment of the present invention, the lower end of the locking member is provided with a plurality of first guide grooves and a plurality of second guide grooves, the first guide grooves and the second guide grooves are arranged alternately with each other along the circumference of the locking member, and the length of the first guide groove is greater than the length of the second guide groove.
[0013] The lower edge of the pressing member has engaging teeth; the upper edge of the cam rotating member has a locking portion, which is configured to contact the engaging teeth; wherein, when the locking portion engages with the first guide groove, the cam rotating member is in a first engagement state with the locking member; when the locking portion engages with the second guide groove, the cam rotating member is in a second engagement state with the locking member.
[0014] As a preferred embodiment of this utility model, the cover plate support is provided with a first mounting groove that cooperates with the fixed sleeve, and the bottom four corners of the cover plate body are each provided with a second mounting groove that cooperates with the upper end of the pressing member.
[0015] As a preferred embodiment of this utility model, the thickness of the cover plate body is 1cm, and when the cover plate body is in the extended position, the bottom surface of the cover plate body is 1cm higher than the top surface of the channel body.
[0016] As a preferred embodiment of this utility model, the cover plate body is provided with a plurality of vertically penetrating drainage holes.
[0017] As a preferred embodiment of this utility model, the channel body is made of corrosion-resistant metal.

The terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implying a number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.
[0036] Please see Figures 1 to 5This utility model provides a push-button drainage channel, including a channel body 1. The two sides of the channel body 1 are recessed to form cover plate support platforms 11. A cover plate body 2 is installed above the cover plate support platforms 11. Multiple vertically penetrating drainage holes 21 are provided on the cover plate body 2, providing a channel for rainwater and other water to enter the drainage channel, ensuring basic drainage function. Spring telescopic pins 3 are provided at each of the four corners of the cover plate body 2 and between them and the cover plate support platforms 11. A compression spring 31 is provided at the lower end of each spring telescopic pin 3. The spring telescopic pins 3 are configured to move downwards under pressure to apply pressure to the compression spring 31, compressing the compression spring 31. The spring telescopic pins 3, with the help of the rebound force of the compression spring 31, lock the cover plate body 2 in the extended and retracted positions. When the cover plate body 2 is in the extended position, the bottom surface of the cover plate body 2 is higher than the top surface of the channel body 1; when the cover plate body 2 is in the retracted position, the top surface of the cover plate body 2 is flush with the top surface of the channel body 1.
[0037] The working principle of the press-type drainage channel is based on the elastic deformation and locking function of the spring telescopic pin 3. When external pressure is applied to the cover body 2, the pressure is transmitted to the spring telescopic pin 3, causing it to move downwards and apply pressure to the compression spring 31 at its lower end. The compression spring 31 is compressed and stores elastic potential energy. As the pressure changes, when certain conditions are met, the spring telescopic pin 3, with the help of the rebound force of the compression spring 31, locks the cover body 2 in the extended position. At this time, the bottom surface of the cover body 2 is higher than the top surface of the channel body 1, increasing the drainage space. When subjected to appropriate pressure again, the locking state of the spring telescopic pin 3 changes. Under the combined action of pressure and spring force, it drives the cover body 2 to lower, eventually locking the cover body 2 in the retracted position. At this time, the top surface of the cover body 2 is flush with the top surface of the channel body 1, restoring normal passage.
[0038] In this embodiment, the press-type drainage channel uses spring-loaded telescopic pins 3, similar to those in a ballpoint pen, installed between the four corners of the cover body 2 and the cover support 11. This allows the cover body 2 to be lifted manually by pressing, thereby increasing the drainage space, preventing blockages, and ensuring the normal operation of the drainage system. When pressed again, the cover body 2 returns to its initial state, eliminating the need for maintenance personnel to manually lift the cover or perform cleaning operations in confined spaces. This significantly simplifies the maintenance process of the drainage channel, saves manpower and time costs, and improves the efficiency of maintenance work.
[0039] It should be noted that the push-button drainage system of this invention can be installed at critical drainage locations in practical applications, while traditional fixed drainage systems can be installed at other drainage locations. When used in conjunction with traditional fixed drainage systems, it can effectively solve drainage problems in key areas while controlling renovation and construction costs. Furthermore, by attaching a warning strip next to the push-button drainage system to prevent accidental stepping, unnecessary triggering is reduced, extending the equipment's lifespan.
[0040] Please see Figure 2 , Figure 4 , Figure 6 In one embodiment, the spring telescopic pin 3 includes a fixed sleeve 32 with an upper opening and a pressing member 33, a locking member 34, a cam rotating member 35, and a compression spring 31 arranged sequentially from top to bottom within the fixed sleeve 32. The lower end of the pressing member 33 passes through the interior of the locking member 34 and abuts against the upper end of the cam rotating member 35. The upper end of the pressing member 33 passes through the upper opening of the fixed sleeve 32 and connects to the cover plate body 2. The upper and lower ends of the compression spring 31 abut against the bottom of the cam rotating member 35 and the bottom plate of the fixed sleeve 32, respectively. The pressing member 33 is configured to move along the length of the locking member 34 inside the locking member 34 and apply pressure to the cam rotating member 35. The cam rotating member 35 is configured to lock the cover plate body 2 in the extended position when in a first engagement state with the locking member 34, and to lock the cover plate body 2 in the retracted position when in a second engagement state with the locking member 34.
[0041] In this embodiment, the spring telescopic toothed column 3 has an ingenious structural design. Through the cooperation of the pressing part 33, locking part 34, cam rotating part 35 and compression spring 31 inside the fixed sleeve 32, the pressing part 33 can move along the locking part 34 and apply pressure to it. The cam rotating part 35 can precisely lock the cover body 2 in the extended position or the retracted position according to different engagement states with the locking part 34, ensuring that the cover body 2 can remain stable in different states and will not move arbitrarily due to external factors (such as water flow impact, slight vibration, etc.), thus ensuring the reliability of the drainage channel under different drainage needs and traffic conditions. Among them, the fixed sleeve 32 provides a closed and stable installation space for the internal components, preventing external debris (such as mud, sand, leaves) from entering the core structure, reducing component wear and failure probability, and extending the service life of the spring telescopic toothed column 3.
[0042] Please see Figure 6 In one embodiment, the lower end of the locking member 34 is provided with a plurality of first guide grooves 341 and a plurality of second guide grooves 342, the first guide grooves 341 and the second guide grooves 342 are arranged alternately along the circumference of the locking member 34, and the length of the first guide groove 341 is greater than the length of the second guide groove 342; the lower edge of the pressing member 33 has an engaging tooth 331; the cam rotating member 35 has a locking part 351 on its upper edge, the locking part 351 being configured to contact the engaging tooth 331; wherein, when the locking part 351 engages with the first guide groove 341, the cam rotating member 35 is in a first engagement state with the locking member 34; when the locking part 351 engages with the second guide groove 342, the cam rotating member 35 is in a second engagement state with the locking member 34.
[0043] In this embodiment, the alternating circumferential arrangement and differing lengths of the first guide groove 341 and the second guide groove 342 provide a clear positioning path for the engaging portion 351 of the cam rotating component 35. When the engaging portion 351 engages with the longer first guide groove 341, the cover body 2 is stably locked in the extended position, ensuring sufficient drainage space during unblocking; when engaged with the shorter second guide groove 342, the cover is locked in the retracted position, ensuring safe passage. The switching between the two states is forcibly limited by the mechanical structure, avoiding ambiguity or accidental switching.
[0044] Please see Figure 7 , Figure 8 In one embodiment, the cover plate support 11 is provided with a first mounting groove 111 that mates with the fixing sleeve 32, and the four bottom corners of the cover plate body 2 are each provided with a second mounting groove 22 that mates with the upper end of the pressing member 33. By providing the first mounting groove 111 on the cover plate support 11 and the second mounting grooves 22 at the four bottom corners of the cover plate body 2, precise assembly with the spring telescopic toothed column 3 is achieved, making the connection between the cover plate support 11 and the cover plate body 2 and the spring telescopic toothed column 3 tighter, reducing the gap and shaking between them. When vehicles or pedestrians pass, abnormal noise or structural displacement caused by loose connection is avoided, improving the stability and safety of the overall structure. When it is necessary to replace or repair the spring telescopic toothed column 3, the clear positioning of the mounting groove makes the component disassembly more convenient, without the need for destructive operation on the cover plate body 2, reducing maintenance costs and difficulty.
[0045] In one embodiment, the cover body 2 is 1 cm thick, and when the cover body 2 is in the extended position, the bottom surface of the cover body 2 is 1 cm higher than the top surface of the channel body 1. That is, when the cover body 2 is in the extended position, the lifting height is only 2 cm, which can effectively avoid the risk of pedestrians and vehicles tripping, bumping, or getting stuck due to the height difference. Since drainage channels are generally located in places where pedestrians and vehicles rarely pass, such as the edge of the road, this further reduces the probability of accidental contact or collision, lowering the possibility of safety accidents. At the same time, it can enhance safety when used in conjunction with warning strips.
[0046] In one embodiment, the channel body 1 is made of steel or other corrosion-resistant metals. Steel and corrosion-resistant metals have high strength and resistance to deformation, and can withstand long-term water flow impact, ground loads (such as vehicle crushing of edges), and natural environmental erosion (such as acid and alkali corrosion in rainwater and sewage), extending the service life of the channel body 1 and reducing maintenance costs caused by damage to the channel body 1. At the same time, the corrosion resistance ensures that the channel body 1 is not prone to rusting and rotting in humid and polluted drainage environments, maintaining the stability of the internal structure of the channel body 1 and avoiding the impact of material deterioration on the supporting performance of the cover plate support 11 (such as deformation of the support causing unstable cover installation).
[0047] In one embodiment, the cover body 2 is made of high-strength plastic. High-strength plastic has a low density, significantly reducing the weight of the cover body 2, lowering the load on the spring telescopic teeth 3, making pressing easier, and reducing wear on the teeth and spring, thus extending the lifespan of core components. Furthermore, the plastic material is resistant to acids and alkalis, and moisture, making it less prone to rusting or aging due to corrosive substances in rainwater and sewage. This makes it suitable for long-term use in humid environments, reducing cracking and damage to the cover due to material deterioration.
[0048] In another embodiment, the cover body 2 can also be made of cast iron. Cast iron has high hardness and strong compressive strength, and can withstand large external loads (such as occasional vehicle running over or heavy objects stepping on it). It is not easy to deform or break, ensuring that the cover maintains its structural integrity during long-term use. It is especially suitable for scenarios such as road edges that may bear certain indirect loads.
[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
[0050] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
