Referring to fig. 1-3, the invention provides a municipal inspection well protection device, which comprises a hollowed-out well cover 1 and a reminding device 2, wherein the hollowed-out well cover 1 can be arranged at the well mouth of the inspection well to partially cover the well mouth of the inspection well, and construction is not affected. Reminding device 2 can set up in the top of fretwork well lid 1, plays the warning effect, and bad weather also can obviously remind danger.

The hollow well lid 1 comprises a fixed outer ring 11 and a plurality of fixing strips 12, wherein the fixed outer ring 11 is arranged at the wellhead of the inspection well, the diameter of the fixed outer ring 11 is larger than that of the wellhead of the inspection well, the plurality of fixing strips 12 are arranged along the circumferential direction of the fixed outer ring 11, each fixing strip 12 comprises a first end 121 and a second end 122 which are oppositely arranged, each first end 121 is fixedly connected with each other at the axial center position of the fixed outer ring 11, and each second end 122 is fixedly connected with the inner side of the fixed outer ring 11, namely the length direction of the fixing strip 12 is identical with the radial direction of the fixed outer ring 11. Adjacent fixing strips 12 and fixing strips 12 form a hollowed-out area 13 in the hollowed-out well lid 1. The surface of each fixing strip 12 is provided with a first fixing hole 123, a second fixing hole 124 and a third fixing hole 125, and the first fixing hole 123 or the second fixing hole 124 or the third fixing hole 125 can be used for fixing the reminding device 2, so that the reminding device 2 plays a role in warning. The hollow well lid 1 can reduce weight and material loss.

As an embodiment, the hollow-out manhole cover 1 further includes a first auxiliary fixing ring 14 and a second auxiliary fixing ring 15 coaxially arranged with the fixing outer ring 11, the diameter of the second auxiliary fixing ring 15 is larger than that of the first auxiliary fixing ring 14, and the first auxiliary fixing ring 14 and the second auxiliary fixing ring 15 are both fixed with the plurality of fixing strips 12. The first auxiliary fixing ring 14 and the second auxiliary fixing ring 15 can further improve the strength of the hollow well lid 1 and further improve the stability of the inspection well wellhead protection device. And the first auxiliary fixing ring 14 and the second auxiliary fixing ring 15 can separate the hollow areas 13, so that the single hollow areas 13 are further separated. When carrying out the drainage work in pit, because the vibration of machine, the drainage hosepipe can rub with the inspection shaft well head, leads to the hosepipe to break, and set up the fretwork area 13 of less area and can restrict the rocking of hosepipe, avoid the fracture of hosepipe, the construction of being convenient for.

As an embodiment, the fixed outer ring 11 is provided with an opening 16, the opening 16 is communicated with the corresponding hollow area 13, and one end of the opening 16 is rotatably connected with a buckle 161 capable of closing the opening 16. The rotation connection structure of the opening 16 and the buckle 161 is the prior art, and will not be described herein. In municipal works, a lot of well lids link to each other with the inspection shaft well head, slope setting in inspection shaft well head one side after opening, and opening 16 can embolia the well lid from opening 16 in the hollow out area 13 (like figure 1), makes this inspection shaft well head protector like this can be used for having the inspection shaft well head of well lid or not having the well lid, and the suitability is strong.

Each vertical rod 22 can be respectively inserted into the first fixing hole 123, or each vertical rod 22 can be respectively inserted into the second fixing hole 124, or each vertical rod 22 can be respectively inserted into the third fixing hole 125, so that the stability of the reminding device 2 is ensured. The side walls of the vertical rods 22 are fixedly connected with limiting rings 221, and the lower ends of the vertical rods 22 can extend to the lower side of the hollow well cover 1. The diameter of the limiting rings 221 is larger than that of the vertical rods 22, and the lower sides of the limiting rings 221 can be respectively abutted against the upper sides of the fixing strips 12, so that the positions of the vertical rods 22 are limited, and the vertical rods 22 are fixed. It should be noted that, insert the montant 22 in locating first fixed orifices 123 or second fixed orifices 124 or third fixed orifices 125, be in order to adjust the position of montant 22, the position of montant 22 can be changed to the different diameters of inspection shaft well head, make the fixed position of montant 22, can make montant 22 and the lateral wall butt of inspection shaft well head, promote the fixed stability of montant 22, in addition, the structure of fixed montant 22 is not necessarily so, as long as can guarantee that montant 22 can vertically fix the upside at fixed strip 12, and each montant 22 lower extreme and the fixed knot structure that the axle center distance is the same of fixed outer lane 11 can both satisfy the demand. The vertical rod 22 and the horizontal rod 21 are arranged on the upper side of the hollow well lid 1 to form an obvious reminding device 2, so that obvious warning and protection can be carried out on the well mouth of the inspection well, the significance of the well mouth protection device of the inspection well is improved, and the personnel is prevented from losing feet and falling.

As an example, the maximum linear distance a between each first fixing hole 123 and the axis of the fixed outer ring 11 is 300mm, and the maximum linear distance b between each third fixing hole 125 and the axis of the fixed outer ring 11 is 400mm. The maximum linear distance between the fixing hole and the axis of the fixed outer ring 11 is the length of the connecting line between the point of the fixing hole furthest from the axis of the fixed outer ring 11 and the axis of the fixed outer ring 11. It will be appreciated that the distance between the first fixing hole 123, the second fixing hole 124 and the third fixing hole 125 and the axis of the fixed outer ring 11 is not limited, but the diameter of the municipal manhole cover is generally 600-800mm, and the positions of the fixing holes are limited so that the lower ends of the vertical rods 22 penetrate through the hollow manhole cover 1 and can be abutted against the side wall of the manhole body.

As an example, the surfaces of both the vertical bars 22 and the horizontal bars 21 may be coated with a light reflecting layer (not shown). Which is convenient for being clearly shown in a low-light environment. It will be appreciated that the surfaces of the vertical bars 22 and the horizontal bars 21 may be provided with other arrangements that promote conspicuity, such as painted with paint of a more pronounced color, such as paint with alternating red and white colors.

As an embodiment, the upper end of each vertical rod 22 is provided with a fixing component 23 for fixing the two cross rods 21. The fixing assembly 23 comprises a vertical sleeve 231 and two transverse sleeves 232, one ends of the two transverse sleeves 232 are fixed at the upper ends of the vertical sleeve 231, the upper ends of the vertical rods 22 can be inserted into the vertical sleeve 231, and the cross rods 21 at the two ends of the transverse sleeves 232 can be respectively inserted into the transverse sleeves 232. Through fixed subassembly 23, can fix montant 22 and two adjacent horizontal poles 21, promote reminding device 2's stability, and can be according to the fixed orifices difference that montant 22 was fixed, dismantle the change fast to horizontal pole 21.

Those skilled in the art will appreciate that the above-described preferred embodiments can be freely combined and stacked without conflict.

It will be understood that the above-described embodiments are merely illustrative and not restrictive, and that all obvious or equivalent modifications and substitutions to the details given above may be made by those skilled in the art without departing from the underlying principles of the invention, are intended to be included within the scope of the appended claims.
