DETAILED DESCRIPTION
[0029] The following will be combined with the drawings Figures 1-2Further details of the application are described below.
[0030] The application discloses an easy-to-maintain overflow well lid.
[0031] With reference to Figure 1 and Figure 2 , the easy-to-maintain overflow well lid comprises a well lid base 1, an overflow well lid 2 and a metal steel mesh 3. An installation ring plate 4 is coaxially fixed on the outer ring of the bottom of the well lid base 1, and a plurality of installation waist holes 41 are arranged on the installation ring plate 4. The overflow well lid 2 is covered on the top of the well lid base 1 and is hingedly arranged on the well lid base 1. A rotating lock 5 is arranged between the side wall, away from the hinge, of the overflow well lid 2 and the well lid base 1. A ring table support 6 is coaxially fixed on the inner ring of the bottom of the well lid base 1, and the metal steel mesh 3 is arranged on the ring table support 6.
[0032] With reference to Figure 1 and Figure 2 , in the process of installing the overflow well lid, first, the well lid base 1 and the overflow well lid 2 are assembled together, and then they are transported to the preset position. The installation ring plate 4 is fixed on the foundation outside the overflow port through a plurality of bolts penetrating through the corresponding installation waist holes 41, so that the installation of the overflow well lid is realized. When the overflow well lid is regularly maintained, the overflow well lid 2 is only opened, and the fallen leaves and sundries on the metal steel mesh 3 can be cleaned. If the hair and other sundries are wound on the metal steel mesh 3, the metal steel mesh 3 can be taken out, carefully cleaned and then put into the well lid base 1.
[0033] With reference to Figure 1 , in order to improve the stability of the assembly of the well lid base 1, a reinforcing rib 7 is welded between the installation ring plate 4 and the outer side wall of the well lid base 1. The reinforcing rib 7 is distributed along the circumference of the well lid base 1.
[0034] With reference to Figure 1 , the well lid base 1 and the overflow well lid 2 are made of high polymer composite materials, which have good corrosion resistance and aging resistance. In the embodiment, polypropylene and polyethylene are selected as main components. The polypropylene and polyethylene materials are not only light but also have excellent mechanical properties.
[0035] With reference to Figure 1 , the overflow well lid 2 is in a semi-spherical cover type and is provided with a plurality of filter holes 21 on the surface. The filter holes 21 are engraved according to the local cultural characteristics and urban landscape and are integrated with the surrounding urban environment, so that the appearance of the sponge city facilities is greatly improved.
[0036] With reference to Figure 1 and Figure 2The inner top of the manhole cover base 1 is provided with a hinge seat 11 corresponding to the hinge. The bottom side of the overflow manhole cover 2 is provided with a rotating lug 22, which is inserted into the hinge seat 11 in the vertical direction, and a fixing bolt 111 is arranged between the hinge seat 11 and the rotating lug 22.
[0037] Referring to Figure 1 The rotating lock 5 includes a fixed block 51 and a lock tongue 52. The fixed block 51 is fixedly arranged on the side wall of the manhole cover base 1, and a lock hole 511 is formed in the fixed block 51. One end of the lock tongue 52 is rotatably connected to the side wall of the overflow manhole cover 2, and the free end is inserted and matched with the lock hole 511 during rotation.
[0038] Referring to Figure 2 The inner top of the manhole cover base 1 is provided with a hinge seat 11 corresponding to the hinge. The bottom side of the overflow manhole cover 2 is provided with a rotating lug 22, which is inserted into the hinge seat 11 in the vertical direction, and a fixing bolt 111 is arranged between the hinge seat 11 and the rotating lug 22. The fixing bolt 111 limits the rotating lug in the hinge seat 11, and the rotating lug and the fixing bolt 111 are rotatably matched.
[0039] Referring to Figure 2 Two pry lever hook holes 31 are symmetrically formed in the radial direction of the metal steel mesh 3. A limiting ring 9 is coaxially fixedly arranged on the inner ring of the manhole cover base 1, located above the ring table support 6, and abuts against the outer ring side wall of the metal steel mesh 3. The limiting ring 9 and the ring table support 6 form a limiting groove 91. Two rollers 32 are rotatably arranged on the outer ring side wall of the metal steel mesh 3 in the radial direction of the metal steel mesh 3. An avoiding opening 92 is formed in the limiting ring 9 corresponding to each roller 32. The roller 32 enters the limiting groove 91 from the avoiding opening 92 and is rotatably matched with the limiting groove 91.
[0040] The implementation principle of the easy-to-maintain overflow manhole cover is that the manhole cover base 1 and the overflow manhole cover 2 made of high polymer composite material significantly improve the corrosion resistance and anti-aging performance of the manhole cover, and reduce the overall weight of the manhole cover. The rotating lock 5 is used to quickly lock and unlock the overflow manhole cover 2, which is not only simple and convenient to operate, but also enhances the safety performance of the manhole cover. When the manhole cover needs to be maintained, the overflow manhole cover 2 can be easily opened, and the fallen leaves and other debris on the metal steel mesh 3 can be easily cleaned, thereby reducing the labor cost and operation time.
[0041] The design of the metal steel mesh 3 ensures the cleanliness of the manhole cover and prevents debris from blocking the drainage effect. At the same time, the design of the limiting ring 9 and the roller 32 ensures the stability and reliability of the metal steel mesh 3 during operation, especially suitable for use in strong rainfall or turbulent water environment, effectively preventing the risk of the metal steel mesh 3 falling off due to vibration.
[0042] In addition, the design of the support bar ears 8 and the ring table support 6 further improves the stability and reliability of the well cover, enabling it to maintain good working condition in various environments. The introduction of the installation ring plate 4 and the reinforcing rib 7 further improves the stability and durability of the well cover base 1, especially suitable for roads and squares in complex geological conditions or rainy areas. This design not only solves the various problems of traditional well covers, but also innovates and optimizes in many aspects, providing strong support for the construction and maintenance of sponge cities.
[0043] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
