DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Referring to FIGS. 1-5, the present invention provides a buried concealable intelligent manhole cover, which comprises: [0018] ground 1, the buried concealable intelligent manhole cover further comprising a fixing frame 2 and elevation mechanisms, the ground 1 including a recessed cavity, the recessed cavity including, in an interior thereof, an upper inside-diameter portion A and a lower inside-diameter portion B, the upper inside-diameter portion A having a diameter that is greater than the lower inside-diameter portion B, so that a ledge portion C is formed between the upper inside-diameter portion A and the lower inside-diameter portion B, the fixing frame 2 being positioned and supported on the ledge portion C.

[0019] Referring to FIGS. 4 and 5, the recessed cavity has a cross-sectional shape that is a T-shape. The fixing frame 2 is mounted on an interior upper surface of the recessed cavity, and a manhole cover 3 is arranged at an upper end of the fixing frame 2. The manhole cover 3 has an elevating function that is controlled by a plurality of uniformly distributed elevation mechanisms. Each of the elevation mechanisms is fixed in the fixing frame 2. An electrical power controller 10, which controls operation of the elevation mechanisms, is buried in the ground 1 at an end of the fixing frame 2, and the electrical power controller 10 is provided therein with wireless communication equipment for communicative interaction with on-ground operators through wireless communication to receive instructions and also to feed information back. An electrical power receiving coil 9 is arranged at an upper end of the electrical power controller 10 for receiving electrical power emitted from an electrical power transmitter of an on-ground (not an under-ground electrical power system) wireless charger and transmitted thereto. (A wireless charging capability of transmitting 2000 W/hour in a distance of 50 centimeters has been realized.). The electrical power controller 10 may receive the electrical power that is received through the electrical power receiving coil 9 and stores electrical energy in a storage capacitor or battery arranged inside the electrical power controller 10, so as to, after being sufficiently charged with electrical energy, implement functions of opening and closing the manhole cover 3. A fixing ring 11 is arranged, as being fixed, at an upper end of the fixing frame 2 and at an outside of the manhole cover 3 for reinforcing a structure capability of the manhole cover 3 and reducing cover-opening resistance. A ground indication frame 4 is mounted on an upper end of the fixing ring 11 for recording a location of the electrical power receiving coil 9 for wireless charging and isolating a top of the manhole cover 3 from an asphalt ground or concrete covering the ground 1.

[0020] The elevation mechanisms comprise reduction gear boxes 6, and a plurality of uniformly distributed reduction gear boxes 6 are mounted on an inside surface of the fixing frame 2. The reduction gear box 6 has an input end to which an electrical machine 7 controlled by the electrical power controller 10 is fixed. The reduction gear box 6 has an output end that is fixedly connected to a lifting bolt 5. Each of the lifting bolts 5 has a nut that is connected to the fixing frame 2. Each of the lifting bolts 5 has an upper end on which the manhole cover 3 is positioned and supported. Symmetrically arranged guide poles 8 are arranged at one side of the reduction gear box 6 to prevent the reduction gear box 6 from rotating when set in operation of rotation and form a track to assist upward and downward sliding of the reduction gear box 6. Each of the guide poles 8 has an upper end fixedly connected to the fixing frame 2. The electrical power controller 10 controls the plurality of uniformly distributed electrical machines 7 to execute an instruction of driving the reduction gear box 6 to rotate and drive the lifting bolt 5 to rotate. The lifting bolts 5 rotating in the interior of the fixing frame 2 drive the manhole cover to move upward, so as to open the manhole cover 3 and completing the function of the elevation mechanism.

[0021] The ground indication frame 4 is formed of multiple frames and is made of a material that is a soft material. The ground indication frame 4 uses the multiple frames to adjust a height difference the frame of the manhole cover 3 and the ground 1.

[0022] The manhole cover 3 is completely buried under the ground 1 at a depth of around 1 centimeter to 50 centimeters and may be covered with a ground material (such as asphalt or concrete) on the surface thereof. The asphalt or concrete ground 1 covering the upper end of the manhole cover 3 and an upper surface of the ground indication frame 4 are kept in flush with an upper end of the ground 1 to enhance levelness of the ground and automobiles and battery-powered vehicles or motorcycles will have excellent experience of being comfortable and having no perception of heterogeneity when passing over the manhole cover 3.

[0023] The operation principle of the present invention is as follows:

[0024] When it is desired to open the manhole cover 3, it only needs that an on-ground operator hand-holds an electrical power transmitter of a wireless charger to perform charging to an indicated location of the electrical power receiving coil 9 (a wireless capacity of transmitting 2000 W/hour in a distance of 50 centimeters being available) to have achieve electrical charging to the electrical power controller 10 of the entire buried concealable intelligent manhole cover 3, and the electrical power controller 10 starts interaction through wireless signals with the operator, so that when the electrical power controller 10 receives an instruction of opening the manhole cover 3, the electrical power controller 10 controls the plurality of uniformly distributed electrical machines 7 to execute an instruction of drive the reduction gear boxes 6 to rotate and drive the lifting bolts 5 to rotate, and the lifting bolts 5 rotating in the interior of the fixing frame 2 cause the manhole cover to move upward to thereby open the manhole cover 3, completing the function of elevation mechanism, and after the operation is done, the ground is restored with a minimum cost (because there is no damage to the ground), and as such, the function of the buried concealable intelligent manhole cover is completed.
