Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent manhole covers, in particular to an automatic opening and closing locking mechanism of an intelligent manhole cover. Background Art

[0002] In today's society with rapid economic development and people's living standards improving, urban construction is also developing rapidly. With the rapid development, urban drainage systems are also increasing, and with it, more and more manhole covers are appearing on the road.

[0003] Since traditional manhole covers simply cover the top of the manhole, or manhole covers with locking structures are simply locked by turning the knob on the outside of the manhole cover, they do not have a certain anti-theft effect. This will cause the manhole covers to be stolen by some criminals, resulting in certain property losses, and also greatly increase the risk factor for passers-by, causing unnecessary safety accidents. Utility Model Content

[0004] The purpose of the present utility model is to provide an intelligent manhole cover automatic opening and locking mechanism, which provides a locking device, specifically, a staff member starts the control box to drive the rotating shaft to rotate clockwise, and the gear drives the push rods to move away from each other and slide inside the limiting bracket 2 through the rotation of the rotating shaft. When the push rod moves and passes through the inside of the limiting bracket 1, the locking is completed, which solves the problem that the traditional manhole cover simply covers the top of the manhole body, or the manhole cover with a locking structure simply completes the locking by turning the knob on the outside of the manhole cover, and has no certain anti-theft effect. This will cause the manhole cover to be stolen by some lawless elements, resulting in certain property losses, and also greatly increases the risk factor for passers-by, causing unnecessary safety accidents.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an intelligent manhole cover automatic opening and locking mechanism, comprising a main frame mechanism, the main frame mechanism comprising a pavement body, the pavement body is in contact with the manhole cover, the bottom of the manhole cover is in contact with the well body, a locking assembly is arranged inside the main frame mechanism, a warning assembly is arranged above the locking assembly, and the locking assembly includes a control box;

[0007] The top of the control box is fixedly connected to the top of the inner wall of the manhole cover, and the bottom of the manhole cover is fixedly connected to a limit plate. The limit plate is rotatably connected to a rotating shaft 1, and the top of the rotating shaft 1 is fixedly connected to the output end of the bottom of the control box. The bottom of the rotating shaft 1 is fixedly connected to a gear, and the front and back sides of the gear are meshed with racks. The two racks are symmetrically arranged with the rotating shaft 1 as the center, and the parts connected to the two racks are the same. The gear drives the corresponding ends of the two racks away from each other through the rotation of the rotating shaft 1. The movement of the racks away from each other drives the push rods to move away from each other and slide inside the limit bracket 2. When the push rod moves and passes through the inside of the limit bracket 1, the lock is completed.

[0008] Furthermore, the top of the rack contacts the bottom of the manhole cover, and two limit brackets 2 are fixedly connected to the bottom of the manhole cover. The interiors of the two limit brackets 2 are slidably connected to the outer surface of the rack, and the end of the rack away from the rotating shaft 1 is fixedly connected to the limit bracket 2. The function of the limit bracket 1 is to prevent the manhole cover from rotating after being locked, causing unnecessary safety accidents.

[0009] Furthermore, two drainage holes are opened inside the manhole cover, and the two drainage holes are of the same size. A limiting ring is fixedly connected to the outer surface of the manhole cover, and the limiting ring is in contact with the top of the well body. Two limiting brackets are fixedly connected to the top of the inner wall of the well body. The insides of the two limiting brackets are adapted to be plugged into the rack. The manhole cover is limited at the top of the well body by the limiting ring, so that the manhole cover will not fall into the well body.

[0010] Furthermore, the warning component includes a solar panel, the bottom of the solar panel is fixedly connected to the top of the manhole cover, the manhole cover is rotatably connected with a rotating shaft 2, the top of the rotating shaft 2 is fixedly connected to the output end of the bottom of the solar panel, the bottom of the rotating shaft 2 is fixedly connected to a rotating plate, the bottom of the rotating plate is fixedly connected to several rotating shafts 3, and several of the rotating shafts 3 are arranged in a circular array. The rotating shaft 2 drives the rotating plate to rotate through the continuous kinetic energy of the solar panel, the rotating shaft 3 drives the ring body to rotate through the rotation of the rotating plate, and the support rod drives the impact block to perform circular motion through the rotation of the ring body.

[0011] Furthermore, several of the three rotating shafts are fixedly connected to a ring body at the bottom, and the bottom of the ring body is rotatably connected to the bottom of the inner wall of the manhole cover. Several support rods are fixedly connected to the outer surface of the ring body, and several of the support rods are arranged in a circular array. The parts connected to the several support rods are the same. Since the impact block will impact the bell shell while moving in a circular motion, the bell shell will drive the telescopic rod one to move toward the inside of the telescopic rod two and squeeze the spring when it is impacted.

[0012] Furthermore, one end of the support rod away from the ring body is fixedly connected to a strike block, and the side of the strike block away from the support rod contacts a bell shell, and the side of the bell shell away from the strike block is fixedly connected to telescopic rod one, and the outer surface of telescopic rod one is slidably connected to telescopic rod two, and the side of telescopic rod one away from the bell shell is fixedly connected to a spring, and the spring is fixedly connected to the side of the inner wall of telescopic rod two away from telescopic rod one, and the side of telescopic rod two away from the ring body is fixedly connected to the inner wall of the manhole cover. When the strike block completes the impact on the bell shell, telescopic rod one will drive the bell shell to reset through the rebound force of the spring. Under the action of the rebound force of the spring, the strike block can continue to impact the bell shell and make a sound while rotating, which serves as a certain warning to passers-by in the society.

[0013] The utility model has the following beneficial effects:

[0014] The utility model provides a locking device. Specifically, the staff starts the control box to drive the rotating shaft to rotate clockwise. The gear drives the push rods to move away from each other and slide inside the limiting bracket 2 through the rotation of the rotating shaft. When the push rod moves and passes through the inside of the limiting bracket 1, the locking is completed. The simple and intelligent operation completes the locking, which greatly reduces the workload of the staff. The intelligent control box also further reduces the probability of the manhole cover being stolen.

[0015] The utility model provides a warning device, specifically, the second rotating shaft drives the ring body to rotate through the continuous kinetic energy of the solar panel, and the rotation of the ring body drives the impact block to make a circular motion. Since the impact block will impact the bell shell while making a circular motion, after the impact block completes the impact on the bell shell, under the action of the rebound force of the spring, the impact block can continue to impact the bell shell and make a sound while rotating, which serves as a warning to passers-by and greatly reduces unnecessary safety accidents.
