[0031] The common manhole covers on the road are all made of ordinary ductile iron die-casting, which is very easy to be lost. The manhole covers are often stolen or washed away by floods. Since there are many manhole covers in a city, it is not easy for the staff to find and manage them in time, which often causes casualties. In view of this, the present invention provides a smart manhole cover. Figures 1 to 3 This is an embodiment of the intelligent manhole cover provided by the present invention.

[0032] See also Figure 1In this embodiment, the intelligent manhole cover 100 includes a manhole cover base 1, a manhole cover body 2, a solar cell assembly and a manhole cover positioning device; the manhole cover base 1 is provided with a mounting portion; the manhole cover body 2 is arranged on the manhole cover base 1, the top of the manhole cover body 2 is provided with a receiving cavity 22, and the bottom of the manhole cover body 2 is provided with a matching portion that matches the mounting portion; the solar cell assembly includes a solar cell panel 31 arranged in the receiving cavity 22, a circuit board electrically connected to the solar cell panel 31, and a battery 32 electrically connected to the circuit board; the manhole cover positioning device is arranged in the receiving cavity 22 of the manhole cover body 2 and is electrically connected to the circuit board, so that the solar cell assembly can provide electrical energy to the battery 32 for continuous use of the manhole cover positioning device. In this embodiment, the manhole cover positioning device can be a satellite positioning system such as GPS (Global Positioning System), and a chip can also be provided on the circuit board to communicate with the municipal monitoring center, so that the municipal monitoring center can understand the position of each of the intelligent manhole covers 100 in real time. The chip, the connection structure between the circuit board and the manhole cover positioning device, the connection structure between the solar circuit board and the circuit board and the battery 32, and the working method of the manhole cover positioning device all belong to the prior art and will not be described in detail here.

[0033] In the technical solution provided by the present invention, the manhole cover base 1 is used to be installed at the sewer outlet. By providing mutually matching mounting parts and matching parts on the manhole cover base 1 and the manhole cover body 2, the manhole cover body 2 is fixed on the manhole cover base 1 and is not easily removed to prevent loss. A solar cell assembly is provided in the manhole cover body 2 to charge the battery 32, and a manhole cover positioning device is provided in the manhole cover body 2. The battery 32 is used to power the manhole cover positioning device. Solar energy is used to provide electrical energy, which can effectively save energy. The manhole cover positioning device can effectively prevent the loss of the smart manhole cover 100.

[0034] In this embodiment, the manhole cover base 1 includes a mounting arm arranged in a ring shape, the inner wall surface of the mounting arm is protrudingly provided with an annular boss 11, and the annular boss 11 is provided with a plurality of positioning holes 111 to form the mounting portion; the bottom of the manhole cover body 2 is protrudingly provided with a plurality of positioning pins 23 corresponding to the plurality of positioning holes 111 to form the matching portion; the positioning pins 23 are correspondingly inserted into the positioning holes 111 to install the manhole cover body 2 on the manhole cover base 1.

[0035] Furthermore, a positioning protrusion 24 is protruding from the end of each positioning pin 23, and the plurality of positioning protrusions 24 are matched with the plurality of positioning holes 111 one by one. That is, each positioning protrusion 24 can be installed in the corresponding positioning hole 111, and after the positioning protrusion 24 is inserted into each positioning hole 111, the manhole cover body 2 can be placed so that the positioning protrusion 24 is matched with the annular boss 11, so as to be buckled at the bottom of the annular boss 11, and when the manhole cover body 2 is pulled up, the manhole cover body 2 cannot be taken out, so that the manhole cover body 2 is installed on the manhole cover base 1.

[0036] For further information, see Figure 2 , the shapes of the plurality of positioning protrusions 24 are different, so that the manhole cover body 2 can be installed in the manhole cover base body 1 only when the corresponding positioning protrusions 24 correspond to the corresponding positioning holes 111; similarly, when the manhole cover body 2 is to be removed, it can only be taken out when the manhole cover body 2 is placed so that the positioning protrusions 24 on the manhole cover body 2 correspond to the positioning holes 111. Therefore, after the installer installs the manhole cover body 2 on the manhole cover base body 1, the manhole cover body 2 is rotated so that the position of the positioning protrusions 24 does not correspond to the positioning holes 111, which can effectively prevent the manhole cover body 2 from being easily stolen. The installer can make a removal mark at the corresponding position to facilitate subsequent inspection and maintenance.

[0037] In this embodiment, please refer to Figure 3 , the shape of each positioning hole 111 corresponds to the shape of each positioning protrusion 24. Of course, the shapes of the positioning holes 111 and the positioning protrusions 24 may not be completely identical, as long as the corresponding positioning protrusion 24 can be placed therein while the other positioning protrusion 24 cannot be placed therein, the configuration should fall within the protection scope of the present application. Specifically, the shape of the positioning protrusion 24 can be set to be circular, elliptical, triangular, square or irregular, etc.

[0038] In this embodiment, at least one of the positioning pins 23 is set as a telescopic rod to avoid operating the manhole cover body 2 when the manhole cover body 2 is forcibly pulled. A sensor can be set at the telescopic part of the telescopic rod, and the sensor is electrically connected to the chip. When the telescopic rod is stretched to extend, the sensor sends a signal to the chip, and the chip can control the alarm sound or send a signal to the municipal monitoring center to prompt someone to steal the smart manhole cover 100, which can effectively prevent theft. The setting method of the sensor and the connection method with the chip are both existing technologies, so they are not explained in detail here.

[0039] In this embodiment, a transparent shell is provided on the top of the manhole cover body 2, and the transparent shell is sealed on the top of the accommodating cavity 22. The solar panel 31 is arranged opposite to the transparent shell so that the solar panel 31 can receive sunlight. The transparent area can be integrally provided with the manhole cover body 2 to prevent water or stains from flowing into the accommodating cavity 22; the transparent area can also be provided as a detachable cover plate to facilitate maintenance of the solar cell assembly. The electric energy obtained by the battery 32 can also be used for other equipment, so that the battery 32 can be replaced regularly by the installer, and the charged battery 32 can be replaced for use by other equipment, so that the solar energy can be effectively utilized and energy can be effectively saved.

[0040] In this embodiment, an assembly hole 21 is provided on the top of the manhole cover body 2, so as to allow an installation tool that matches the assembly hole 21 to install the manhole cover body 2 on the manhole cover base body 1. The assembly hole 21 can be provided in the transparent area or outside the transparent area to facilitate the rotation of the manhole cover body 2.

[0041] Specifically, the assembly hole 21 is configured as a hexagonal screw hole so that the manhole cover body 2 can be rotated onto the manhole cover base body 1 by a hexagonal wrench, so that the manhole cover body 2 is not easily removed.

[0042] In this embodiment, a plurality of mounting holes are further provided on the manhole cover base 1, and connecting screws are respectively passed through the plurality of mounting holes to mount the manhole cover base 1 to the connecting seat at the sewer outlet.

[0043] When installing the smart manhole cover 100, first install the manhole cover base 1 to the sewer outlet by screws, and then use a hexagonal wrench to rotate the manhole cover body 2 into the positioning hole 111 on the manhole cover base 1 to rotate it a certain angle so that the manhole cover body 2 is installed and not easily removed.

[0044] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, is also included in the patent protection scope of the present invention.
