[0027] In order to enable people skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work should fall within the scope of protection of the present invention.

[0028] At the same time, the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like cited in this specification indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0029] At the same time, in the description of this specification, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0030] Current construction protection devices mostly use static physical isolation structures, such as fixed guardrails, warning signs, and triangular traffic cones. However, these devices cannot be adjusted according to real-time changes in the construction site environment, posing safety hazards and inefficient management.

[0031] For example, when protecting the manhole cover after construction, guardrails, warning signs, triangular road cones, etc. can only protect one side of the manhole cover and are easy to fall over, especially in dim light. It is more inconvenient for pedestrians to find the existence of the protective device, and the protection effect is poor.

[0032] Therefore, the design concept of this application is to design a protective device specifically for manhole covers, which can not only protect the manhole covers in all directions, but also use the manhole covers themselves for installation and fixation, so there will be no problem of tipping over. In addition, the obvious alarm mechanism set up can also remind pedestrians of the existence of the protective device when the light is dim, thereby avoiding safety accidents.

[0033] like Figure 1-2 As shown, the present application provides a manhole cover protection device for road construction, comprising a protective grille frame 2 detachably connected to the manhole cover 1, an outer flange grille plate 3 being provided at the edge of the protective grille frame 2, a reflective layer being provided on the outer wall of the protective grille frame 2, and the protective grille frame 2 being connected to an alarm mechanism.

[0034] The ventilation hole of the manhole cover 1 is connected with a bolt 4, and the bolt 4 is threadedly connected to the protective grille frame 2; the bolt 4 is connected with a lower nut 5 after passing through the ventilation hole; a connecting hole is provided on the protective grille frame 2, and the bolt 4 is connected with an upper nut 6 after passing through the connecting hole.

[0035] During installation, first pass the bolt 4 through the ventilation hole to connect the lower nut 5, and install the bolt 4 on the manhole cover 1. Then cover the protective grille frame 2 on top of the manhole cover 1. The connecting holes on the protective grille frame 2 should be aligned with the bolt 4. After the bolt 4 passes through the connecting hole, it is connected with the upper nut 6, and the installation of the protective device is completed; this application uses the bolt 4, the ventilation hole of the manhole cover 1, the lower nut 5, the connecting hole on the protective grille frame 2 and the upper nut 6 to utilize the manhole cover 1 itself to install and fix the device, which has better stability in use and will not have the problem of tipping over.

[0036] Among them, a lower flange 7 is provided at the bottom of the outer flange grille plate 3; after the construction of the manhole cover 1, the surrounding area has not dried completely, and the lower flange 7 can raise the outer flange grille plate 3, leaving a distance between the outer flange grille plate 3 and the construction surface, which is more conducive to the drying of the construction surface.

[0037] Among them, the reflective layer adopts reflective strips or reflective coatings; the reflective layer can be reflective strips applied on the outer wall of the protective grille frame 2 and the outer wall of the outer flange grille plate 3, or it can be reflective paint coated on the outer wall of the protective grille frame 2 and the outer wall of the outer flange grille plate 3. The user can decide which reflective layer to use according to his own situation.

[0038] The alarm mechanism includes a solar strobe light 8, which is threadedly connected to the protective grille frame 2. The solar strobe light 8 can be purchased directly online. The continuously flashing strobe light is particularly eye-catching and can effectively avoid being ignored by pedestrians.

[0039] Among them, the alarm mechanism includes a solar induction alarm, which is threadedly connected to the protective grille frame 2; the solar induction alarm can be purchased directly online. The solar induction alarm not only has a flashing strobe light that is particularly eye-catching, but also can issue a sound warning to the human body approaching at a close distance, further avoiding being ignored by pedestrians.

[0040] Although the present invention has been described in detail with reference to the accompanying drawings and in combination with preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, ordinary technicians in this field can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all be within the scope of the present invention. Any technician familiar with this technical field can easily think of changes or substitutions within the technical scope disclosed in the present invention, and they should all be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
