[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model
[0024] Embodiment 1
[0025] Please refer to Figures 1-4 , A manhole cover with a locking structure, including a manhole cover body 1. The manhole cover body 1 includes an installation frame 101, a manhole cover frame 102 welded to the upper surface of the installation frame 101, a manhole cover plate 103 hinged outside the manhole cover frame 102, and a locking structure 106 provided on the manhole cover frame 102 and the manhole cover plate 103; The locking structure 106 includes a locking block 1061 fixedly installed outside the manhole cover plate 103, a socket 1062 fixedly installed on the side of the manhole cover frame 102 away from the manhole cover plate 103, a biaxial motor 1064 fixedly installed on the inner bottom wall of the socket 1062, a lead screw 1065 fixedly installed on the output shaft of the biaxial motor 1064, a slide seat 1066 threadedly connected to the outside of the lead screw 1065, and a clamping rod 1067 welded to one side of the slide seat 1066 and inserted into the locking block 1061
[0026] Among them, a connecting hinge 104 is provided between the manhole cover frame 102 and the manhole cover plate 103. A plurality of anti-slip bumps 105 are installed on the side of the manhole cover plate 103 away from the manhole cover frame 102. By installing the anti-slip bumps 105, the anti-slip property of the manhole cover plate 104 can be increased, preventing slipping when pedestrians come into contact. Installation holes for fixing the manhole cover body 1 are provided inside the installation frame 101.
[0027] In this embodiment, a slot 1063 is provided inside the socket 1062. The locking block 1061 is inserted into the slot 1063. A slot 1068 adapted to the latch rod 1067 is provided inside the locking block 1061, and the latch rod 1067 is inserted into the slot 1068. An installation bracket 1069 is welded to the outside of the bi-axial motor 1064, and the bi-axial motor 1064 is installed on the inner bottom wall of the socket 1062 through the installation bracket 1069. A battery box 107 electrically connected to the bi-axial motor 1064 is installed on the side wall of the socket 1062.
[0028] It should be noted that the number of the lead screws 1065 and the sliding seats 1066 in the locking structure 106 is two each. The two lead screws 1065 are respectively installed on the two output shafts of the bi-axial motor 1064. The two sliding seats 1066 are symmetrically arranged on the two lead screws 1065. The two lead screws 1065 are connected to the inner walls of the opposite sides of the socket 1062 through bearings, and the threads on the two lead screws 1065 are arranged in opposite directions. A limiting structure for limiting the two sliding seats 1066 is provided inside the socket 1062.
[0029] When this embodiment is in use, the manhole cover plate 103 is flipped to insert the locking block 1061 into the slot 1063 to achieve the preliminary fixation of the manhole cover plate 103. Then, the bi-axial motor 1064 is started to drive the lead screw 1065 to rotate. Since the threads on the two lead screws 1065 are opposite, the two sliding seats 1066 are displaced relative to each other to insert the latch rod 1067 into the slot 1068, further fixing the manhole cover plate 103.
[0030] Embodiment Two:
[0031] Please refer to Figure 4 , on the basis of Embodiment One, a protection structure 2 is provided inside the manhole cover frame 102. The protection structure 2 includes a square frame 201 and a protection net 202 welded to the outside of the square frame 201. Installation platforms 204 are welded to the four corners inside the manhole cover frame 102, and locking bolts 203 connected to the four installation platforms 204 are installed inside the four corners of the square frame 201.
[0032] By adopting the above technical solution, the inside of the manhole cover body 1 is protected, preventing pedestrians from falling into the sewer, thus protecting pedestrians.
[0033] The working principle of the above embodiment is:
[0034] During use, turn over the well cover plate 103 and insert the locking block 1061 into the slot 1063 to achieve the preliminary fixation of the well cover plate 103. Then, start the dual-axis motor 1064 to drive the lead screw 1065 to rotate. Since the threads on the two lead screws 1065 are opposite, the two sliding seats 1066 displace relative to each other to insert the latch 1067 into the card slot 1068, further fixing the well cover plate 103. Through the drive of the dual-axis motor 1064, the well cover plate 103 can be quickly opened and closed.
[0035] All electrical components mentioned in the text are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer for control, and the existing publicly disclosed power connection technology will not be elaborated in the text.
