Description

Technical Field

[0001] This utility model belongs to the field of drainage technology, and in particular relates to a high-efficiency highway drainage device. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material, such as metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers. They are generally round. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc., and are required in the construction of municipal roads.

[0003] A conventional patent with publication number CN217053698U discloses a manhole cover snap-fit ​​structure for municipal road engineering, including a manhole cover body. The lower end of the manhole cover body is provided with a connecting seat, and a pin is installed on the inner side of the connecting seat. A cylindrical groove is opened at the connection between the pin and the manhole cover body. A threaded rod is provided at the upper end of the connecting seat, and an adjusting nut is installed on the outer surface of the side end of the threaded rod. By setting up a pin, a cylindrical groove, a snap-fit ​​block, a spring, a first movable groove, a sliding groove, and a snap-fit ​​groove, the snap-fit ​​block can slide into the snap-fit ​​groove through the sliding groove, which can effectively limit and fix the manhole cover body and prevent large water flows from washing the manhole cover body open. By setting up a threaded rod, an adjusting nut, a connecting rod, and a second movable groove, it is convenient to remove the snap-fit ​​block from the snap-fit ​​groove on the manhole cover body, making it easy to open the manhole cover body.

[0004] However, traditional technology has some problems: the threaded rod of the traditional device protrudes above the upper end of the manhole cover body, and the installation of the adjusting nut makes the manhole cover able to be opened by anyone, failing to achieve the purpose of locking and clamping. When the adjusting nut is removed, the threaded rod protruding to the outside can easily affect the car tires and is itself subject to wear. Therefore, we propose a high-efficiency highway drainage device. Utility Model Content

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention provides a high-efficiency highway drainage device, including a manhole cover seat 1 and a manhole cover plate 2. The manhole cover plate 2 is rotatably mounted on the manhole cover seat 1 via a pin. The manhole cover seat 1 is provided with an installation hole 13 and symmetrical movable grooves 11. A retractable snap-fit ​​part 4 is provided in the installation hole 13. The manhole cover plate 2 is provided with a snap-fit ​​groove 22 corresponding to the snap-fit ​​part 4. A movable fixing part 3 is provided in the symmetrical movable grooves 11. The manhole cover plate 2 is provided with symmetrical fixing grooves 21, and the fixing grooves 21 cooperate with the fixing parts 3.

[0027] In use, the aforementioned high-efficiency highway drainage device closes the manhole cover 2, which rotates along the pin shaft to cover the manhole cover seat 1. The locking block 41 contacts the inclined groove, causing the locking block 41 to move and retract on the connecting rod 42, pushing the fixing spring 43 to compress. At the same time, the protruding part of the fixing member 31 slides upward from the fixing groove 21. After installation, the fixing spring 43 pushes the locking block 41 to move along the connecting rod 42 and extend into the fixing hole of the locking groove 22, fixing the manhole cover 2. A tool with a corresponding through hole shape is inserted into the through hole of the fixing member 31, and the fixing member 31 is moved to move between the movable groove 11 and the fixing groove 21 to improve the fixing effect. After the cover is closed, the lower end of the manhole cover 2 contacts the rubber ring 12 of the manhole cover seat 1, reducing wear and noise, and achieving the functions of protection and noise reduction.

[0028] In this embodiment, the snap-fit ​​part 4 includes a T-shaped snap-fit ​​block 41, a connecting rod 42, and a fixing spring 43. The snap-fit ​​block 41 has a stepped hole 411. One end of the connecting rod 42 is fixed in the mounting hole 13, and the other end is slidably installed in the stepped hole 411. The fixing spring 43 is wrapped around the outer wall of the connecting rod 42, and its two ends are in contact with the inner wall of the mounting hole 13 and the end face of the snap-fit ​​block 41, respectively. Through the snap-fit ​​block 41, the connecting rod 42, and the fixing spring 43, the snap-fit ​​block 41 can be extended and retracted, which facilitates the closing of the quick-closing manhole cover 2. The snap-fit ​​groove 22 includes a sloping groove at the lower end and a fixing hole. The front end of the snap-fit ​​block 41 is a sloping surface. During installation, the snap-fit ​​block 41 is slidably connected to the sloping groove. After fixing, the snap-fit ​​block 41 extends into the fixing hole, and the manhole cover 2 is snapped and fixed through the snap-fit ​​block 41 extending into the fixing hole.

[0029] The design of the snap-fit ​​part 4 allows the snap-fit ​​block 41 to extend and retract via the connecting rod 42 and the fixing spring 43, ensuring that the manhole cover 2 can be snapped in quickly when closed. The inclined groove and fixing hole design of the snap-fit ​​groove 22 allow the snap-fit ​​block 41 to slide smoothly and snap into the fixing hole, thereby achieving a stable snap-fit ​​effect.

[0030] In this embodiment, the fixing part 3 includes an L-shaped fixing member 31, which is slidably connected in the movable groove 11. It passes through the movable groove 11 and is slidably connected to the fixing groove 21, thereby improving the fixing effect by extending the fixing member 31 into the fixing groove 21. The upper end of the fixing member 31 is flush with the end face of the manhole cover seat 1, and its end face has a through hole. The through hole is round, square, or triangular to reduce wear and to achieve the purpose of locking by requiring a corresponding tool to open.

[0031] The design of the fixing part 3 allows the fixing member 31 to slide within the movable groove 11 and the fixed groove 21, and the through hole design requires a specific tool to open, thereby improving the fixing effect and safety. The diverse shapes of the through holes ensure that only specific tools can open the manhole cover 2 to achieve the locking purpose.

[0032] In this embodiment, an unlocking component 5 is also included. The manhole cover plate 2 is provided with an insertion hole 23 and a rotating groove 24. The unlocking component 5 is inserted into the manhole cover plate 2 through the insertion hole 23 and placed in the rotating groove 24. The unlocking component 5 is provided with a vertical pressing rod 51 and a horizontally symmetrical unlocking block 52 inside. The front end of the pressing rod 51 is provided with a pushing block 511. The pushing block 511 pushes the symmetrical unlocking blocks 52 to move to both ends. The unlocking block 52 cooperates with the locking block 41. When in use, the unlocking component 5 is inserted into the manhole cover plate 2 through the insertion hole 23 and placed in the rotating groove 24. The unlocking component 5 is rotated so that it corresponds to the locking block 41. Then, the pressing rod 51 is pressed so that the pushing block 511 pushes the unlocking block 52 to push the locking block 41 out of the fixing hole of the locking groove 22, thereby unlocking and making it easier to lift the manhole cover plate 2.

[0033] The design of the unlocking component 5 allows the manhole cover 2 to be opened when it needs to be opened. The unlocking component 5 can be inserted through the insertion hole 23 and the rotating groove 24, and the locking block 41 can be pushed out of the fixing hole of the locking groove 22 by the cooperation of the pressing rod 51 and the unlocking block 52, thereby unlocking and facilitating the lifting of the manhole cover 2. This design ensures convenient unlocking and lifting of the manhole cover 2, improving operational efficiency.

[0034] In this embodiment, the outer walls of the pressing rod 51 and the two unlocking blocks 52 are provided with reset components. The three reset components each include a limiting plate 54 and a reset spring 53. The limiting plate 54 is fixed to the outer walls of the pressing rod 51 and the two unlocking blocks 52 respectively. The reset spring 53 is wrapped around the outer walls of the pressing rod 51 and the two unlocking blocks 52. The unlocking component 5 has three limiting grooves that cooperate with the limiting plate 54. Both ends of the reset spring 53 are connected to the limiting plate 54 and the limiting grooves. By pushing the limiting plate 54 through the reset spring 53, the pressing rod 51 and the unlocking blocks 52 are reset after the pressing rod 51 is released.

[0035] The reset assembly is designed so that the pressing rod 51 and the unlocking block 52 can automatically reset after use, ensuring the reusability and efficient operation of the unlocking component 5. The cooperation between the limiting plate 54 and the reset spring 53 ensures that the pressing rod 51 and the unlocking block 52 can quickly reset after being released, improving the reliability and ease of operation of the unlocking component 5.

[0036] In this embodiment, the manhole cover seat 1 is provided with a rubber ring 12, and the lower end of the manhole cover plate 2 contacts the rubber ring 12. By having the rubber ring 12 contact the lower end of the manhole cover plate 2, the wear between the manhole cover plate 2 and the manhole cover seat 1 and the noise generated therefrom are reduced, thereby achieving the functions of protection and noise reduction.

[0037] The design of the rubber ring 12 effectively reduces wear and noise between the manhole cover plate 2 and the manhole cover seat 1, ensuring the service life of the manhole cover plate 2 and the comfort of the operating environment during use. Through the buffering effect of the rubber ring 12, the manhole cover plate 2 and the manhole cover seat 1 are effectively protected, achieving the purpose of protection and noise reduction.

[0038] The working principle of this utility model:

[0039] When in use, close the manhole cover plate 2. The manhole cover plate 2 rotates along the pin shaft to cover the manhole cover seat 1. The locking block 41 contacts the inclined groove, causing the locking block 41 to move and retract on the connecting rod 42, pushing the fixing spring 43 to compress. At the same time, the protruding part of the fixing member 31 slides upward from the fixing groove 21. After installation, the fixing spring 43 pushes the locking block 41 to move on the connecting rod 42 and extend into the fixing hole of the locking groove 22, fixing the manhole cover plate 2. Insert the tool with the corresponding through hole shape into the through hole of the fixing member 31 and move the fixing member 31 to move between the movable groove 11 and the fixing groove 21 to improve the fixing effect. After the cover is closed, the lower end of the manhole cover plate 2 contacts the rubber ring 12 of the manhole cover seat 1 to reduce wear and noise, achieving the functions of protection and noise reduction.

[0040] Open the cover plate, insert the tool with the corresponding through hole shape into the through hole of the fixing member 31, move the fixing member 31 so that it moves between the movable groove 11 and the fixed groove 21, and align it with the opening of the fixed groove 21. Then insert the unlocking member 5 into the manhole cover plate 2 through the insertion hole 23 and place it in the rotating groove 24. Rotate the unlocking member 5 by 90° so that it aligns with the snap block 41. Press the pressing rod 51. The pressing rod 51 pushes the pushing block 511 at the lower end, so that the unlocking blocks 52 at both ends extend outward and push the snap block 41 to retract and separate from the fixed hole, thereby unlocking. Lift the unlocking member 5 and quickly open the manhole cover plate 2.

[0041] When using the unlocking component 5, the pressing rod 51 and the unlocking block 52 move, respectively driving the limiting plate 54 on their outer wall to move in the limiting groove and compressing the reset spring 53. After opening the cover, the pressing rod 51 is released, and the reset spring 53 pushes the limiting plate 54 to reset, thereby resetting the unlocking block 52 and the pressing rod 51, making it convenient to remove the unlocking component 5 from the insertion hole 23.
