[0033] In order to keep the following description of the embodiments of the present utility model clear and concise, the detailed descriptions of known functions and known components are omitted in the present utility model.
[0034] Embodiment 1
[0035] Please refer to Figure 1-7 As shown, in this embodiment, a stainless steel manhole cover is provided, including: a manhole cover body 1 and a mounting seat 2.
[0036] The manhole cover body 1 is made of a high wear-resistant stainless steel material with a lightweight design to meet the requirements of load-bearing and durability; a mounting collar 9 is fixedly installed at the bottom of the manhole cover body 1, and the mounting collar 9 is slidably matched with the inner wall of the mounting seat 2, so that the manhole cover body 1 can be closely and stably installed on the top of the mounting seat 2; the mounting seat 2 is fixedly embedded in the drain outlet to ensure the stability of the entire manhole cover.
[0037] To achieve the drainage function, a plurality of drainage holes 7 are opened inside the manhole cover body 1. These drainage holes 7 are evenly distributed, enabling external accumulated water to smoothly enter the drainage port.
[0038] To fix the manhole cover body 1 and the mounting seat 2, a unique fixing component is designed in this embodiment; the fixing component includes four fixing columns 11 fixedly installed at the bottom of the mounting collar 9. These fixing columns 11 are equidistantly arranged. Among them, sliding sleeves of the outer walls of two fixing columns 11 are provided with movable rings 12, and the outer walls of the other two fixing columns 11 are fixedly sleeved with fixing rings 16; limiting protrusions 13 are fixedly installed on the outer walls of both the movable ring 12 and the fixing ring 16. These limiting protrusions 13 are in sliding fit with the annular grooves 4 opened on the inner wall of the mounting seat 2; in addition, four cover-taking grooves 5 are opened on the mounting seat 2. One end of these cover-taking grooves 5 penetrates through the top of the mounting seat 2, and the other end is communicated with the annular groove 4, so as to disassemble the manhole cover through the cover-taking groove 5 when needed.
[0039] Furthermore, the fixing component further includes two limiting grooves 6 opened on the inner wall of the bottom of the annular groove 4. These two limiting grooves 6 are respectively matched with the limiting protrusions 13 on the outer walls of the two movable rings 12 to ensure that the movable ring 12 can complete the rotational limit of the manhole cover body 1 when in a specific position; to achieve this function, springs 14 are sleeved on the outer walls of both fixing columns 11 installed with the movable rings 12. One end of the spring 14 is fixedly connected to the bottom of the mounting collar 9, and the other end is fixedly connected to the top of the adjacent movable ring 12. In this way, the spring 14 can continuously apply a downward thrust to the movable ring 12 to ensure that the limiting protrusion 13 on its outer wall can continuously be located in the limiting groove 6, realizing the continuous rotational limit of the manhole cover body 1.
[0040] In addition, the two movable rings 12 are fixedly connected by a connecting rod 15. Above the connecting rod 15, a fixing plate 17 is fixedly installed through a connecting rod. The fixing plate 17 is located directly above the drainage hole 7 at the center of the manhole cover body 1 and is matched with the cover opener 3 to realize the lifting and unlocking of the two movable rings 12.
[0041] Furthermore, in this embodiment, the structure of the cover opener 3 is described in detail; the cover opener 3 is composed of a lifting frame 18, a mounting bracket 19, and a fixing rod 20. The lifting frame 18 is fixedly installed below the mounting bracket 19, and their shapes and sizes are both matched with the drainage hole 7 at the center of the manhole cover body 1 to ensure that the cover opener 3 can smoothly pass through the manhole cover body 1; the holes inside the lifting frame 18 are matched with the fixing plate 17. When the lifting frame 18 moves below the fixing plate 17, by rotating the cover opener 3, it can be ensured that the pulling frame 18 is matched with the protruding parts on both sides of the fixing plate 17. Then, by lifting operation, the two movable rings 12 can be driven to rise, thereby releasing the fixation between the manhole cover body 1 and the mounting seat 2; the fixing rod 20 is fixedly installed at the top of the mounting bracket 19, and a handle 21 is provided at its top end to facilitate the operation of the user.
[0042] This application can be used in the technical field of stainless steel manhole covers and can also be used in other fields applicable to this application.
[0043] Example 2
[0044] Reference Figure 3 、 4 , on the basis of Example 1, an improved high-wear-resistant and lightweight integral stainless steel manhole cover is applied to the technical field of stainless steel manhole covers;
[0045] In order to further enhance the load-bearing capacity of the manhole cover body 1, in this embodiment, reinforcing ribs 10 are fixedly installed on the inner wall of the installation collar 9. These reinforcing ribs 10 are closely attached to the bottom of the manhole cover body 1, effectively improving the stability and load-bearing capacity of the overall structure.
[0046] In addition, in order to improve the anti-slip performance of the manhole cover surface, a plurality of bumps 8 are fixedly installed on the top of the manhole cover body 1. These bumps 8 not only increase the friction force on the surface of the manhole cover body 1 but also improve the walking safety of pedestrians.
[0047] The usage process and working principle of the technical solution of the present utility model are as follows:
[0048] In use, the user can use concrete to fixedly embed the mounting base 2 at the drain outlet of the sewer, and then the manhole cover body 1 can be installed on the mounting base 2. During installation, the user can align multiple limiting protrusions 13 with the corresponding cover-taking grooves 5, and make the multiple limiting protrusions 13 slide into the annular groove 4 through the cover-taking grooves 5. At the same time, the manhole cover body 1 will also be slidably clamped into the mounting base 2 through the mounting collar 9 below until the manhole cover body 1 covers the top of the mounting base 2. Then the user can rotate the manhole cover body 1, and the multiple limiting protrusions 13 will rotate synchronously with the manhole cover body 1. When the limiting protrusion 13 installed on one side of the movable ring 12 moves to correspond to the limiting groove 6, under the action of the spring 14, the movable ring 12 will be pushed downward, and finally the limiting protrusion 13 on one side of it can be clamped into the limiting groove 6. In this state, the two movable rings 12 and the limiting protrusions 13 on one side of them will limit the rotation of the manhole cover body 1, and the two fixed rings 16 and the limiting protrusions 13 on one side of them will limit the manhole cover body 1 from moving up and down. At this time, the firm installation of the manhole cover body 1 can be completed. When the manhole cover body 1 is in use, external accumulated water can enter the drain outlet through the multiple drain holes 7 opened in the manhole cover body 1. At the same time, the lower part of the manhole cover body 1 is provided with reinforcing ribs 10, which can also ensure that the load-bearing capacity of the manhole cover body 1 is good and can avoid the occurrence of falling accidents. When the manhole cover body 1 needs to be disassembled, the user needs to extend one end of the cover-opening tool 3 into the lower part of the manhole cover body 1 through the drain hole 7 to ensure that the lifting frame 18 passes through the corresponding fixed plate 17 below. Then the user can rotate the lifting frame 18, and the lifting frame 18 will cooperate with the protruding parts at both ends of the fixed plate 17. At this time, lifting the cover-opening tool 3 upward can drive the fixed plate 17 to rise, and then the synchronous rise of the two movable rings 12 can be completed. At this time, multiple limiting protrusions 13 are all located in the annular groove 4, and the user can rotate the manhole cover body 1 until the multiple limiting protrusions 13 are aligned with the corresponding cover-taking grooves 5, and then the manhole cover body 1 can be pulled upward to complete the disassembly, which is convenient for the maintenance of the manhole cover body 1 or the drainage system and is convenient to use.
