Description

Technical Field

[0001] The present invention relates to the technical field of manhole covers, and in particular to an electric theft-proof manhole cover. Background Art

[0002] ‌Power manhole covers‌ refer to covers used to cover power facilities, usually installed on underground power equipment in public places such as streets and squares, such as power lines, substations, etc. The main function of power manhole covers is to protect power facilities and prevent people and objects from accidentally touching and getting electric shocks. It also facilitates the power department to inspect and maintain power equipment. ‌Power manhole covers are usually made of cast iron. Cast iron manhole covers are often stolen because of their recycling value. Therefore, they often cause "biting people" and "biting cars" at the wellheads, which not only causes losses to national property, but also poses safety hazards to pedestrians and vehicles.

[0003] For example, an electric anti-theft manhole cover disclosed in the patent with announcement number CN219157767U requires specific tools to open the manhole cover, which causes the staff to carry more tools when working, which is inconvenient to use. In addition, thieves can also imitate the "key" to unlock the manhole cover, which reduces the safety of use. Therefore, it is urgent to design an electric anti-theft manhole cover.

Two symmetrically arranged stoppers 16 are also fixed inside the third circular groove 9. The first opening groove 13, the second opening groove 14 and the third opening groove 15 are all staggered with each other, and the degree of staggered between the first opening groove 13, the second opening groove 14 and the third opening groove 15 is an integer, which is convenient for the staff to rotate. Each of the first opening groove 13, the second opening groove 14 and the third opening groove 15 is provided with a slide groove 17 on both sides of the bottom, and a slide plate 18 is slidably installed inside each slide groove 17, and the bottom of each slide plate 18 is a friction surface. Two centrally symmetrically arranged vertical grooves 12 are vertically arranged on the inner wall of the mounting seat 1, and each vertical groove 12 is connected to the first circular groove 7, the second circular groove 8 and the third circular groove 9, and each vertical groove 12 is hinged with three evenly distributed one-way baffles 10 through a one-way elastic hinge; Preferably, it not only enables the staff to unlock the door conveniently, but also prevents the criminals from unlocking the door, and further can reset the lock slot assembly damaged by the criminals.

[0023] Please refer to the attached Figure 1 In a preferred embodiment, two symmetrically arranged plug holes 3 are opened on the top of the manhole cover body 2, and both plug holes 3 pass through the manhole cover body 2; Furthermore, the insertion hole 3 facilitates the rotation and lifting of the manhole cover body 2 , which can be rotated and lifted by buckling the inner wall of the insertion hole 3 , and can be accurately rotated by the degree scale 5 .

[0024] The working principle of the present invention is as follows: first, the mounting base 1 is embedded in the ground, and then the two L-shaped brackets 4 are inserted into the two vertical grooves 12. Due to the setting of the one-way baffle 10, the horizontal side of the L-shaped bracket 4 can be smoothly inserted into the third circular groove 9, and then the manhole cover body 2 is rotated at will so that the one-way baffle 10 at the bottom can be reset, and the installation of the manhole cover body 2 can be completed; When the staff needs to disassemble the manhole cover body 2, first rotate the manhole cover body 2 through the socket 3 to make the horizontal edge of the L-shaped bracket 4 contact with the stopper 16, then rotate the manhole cover body 2 to drive the L-shaped bracket 4 to rotate a specified angle, so that the horizontal edge of the L-shaped bracket 4 is aligned with the third opening groove 15, and lift the manhole cover body 2 upwards, so that the horizontal edge of the L-shaped bracket 4 moves upwards and enters the second circular groove 8, and then rotate the horizontal edge of the L-shaped bracket 4 in the second circular groove 8 by a specified angle, and lift the manhole cover body 2 upwards, so that the horizontal edge of the L-shaped bracket 4 enters the first circular groove 7, and finally rotate the horizontal edge of the L-shaped bracket 4 in the first circular groove 7 by a specified angle, and lift the manhole cover body 2 upwards to separate the L-shaped bracket 4 and the mounting seat 1 to complete the unlocking. It should be noted that the angles in the first opening groove 13, the second opening groove 14, the third opening groove 15 and the stopper 16 bracket are preset angles, which are not fixed; When non-staff members dismantle the manhole cover, firstly, the criminals cannot clearly know how much angle to rotate. Even if the criminals lift the manhole cover body 2 upwards, so that the top of the horizontal side of the L-shaped bracket 4 contacts the top of the third circular groove 9 and rotates, when the manhole cover body 2 is rotated in this way, the horizontal side of the L-shaped bracket 4 contacts the friction surface of the slide plate 18 and moves the slide plate 18, and the slide plate 18 blocks the third opening groove 15. In summary, the criminals cannot steal the manhole cover body 2; When non-staff members rotate the manhole cover body 2 so that the slide plate 18 blocks the third opening slot 15, the staff can open the manhole cover in a normal manner. When the L-shaped bracket 4 body cannot be lifted into the second circular slot 8, it indicates that the slide plate 18 blocks the third opening slot 15. Then the staff member needs to lift the manhole cover body 2, make the horizontal side of the L-shaped bracket 4 contact with the slide plate 18, and rotate the horizontal side of the L-shaped bracket 4 so that the slide plate 18 slides into the inside of the slide slot 17 again, and then the lock can be unlocked again. It should be noted that the contact surface between the slide plate 18 and the slide slot 17 is rough, which increases the stability of the slide plate 18, and because the length of the slide plate 18 is greater than the length of the opening slot, the slide plate 18 will not separate from the slide slot 17. In summary, not only does it not require special tools to facilitate the staff to unlock and disassemble the manhole cover body 2, it can also prevent the occurrence of theft of the manhole cover body 2 by lawless elements, thereby improving the use effect of the device.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
