They can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers, etc. according to the material. They are generally round and can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc.

[0003] There are often manhole covers on crosswalks, and there are ventilation holes on the surface of the manhole covers. The ventilation holes on the existing manhole covers do not have any protective measures, resulting in objects such as coins easily falling into the manhole covers through the ventilation holes, and the manhole covers are difficult to open, making it difficult to take out the fallen objects. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an intelligent manhole cover.

[0008] Preferably, a spring sheet is provided inside the telescopic plate, and two ends of the spring sheet are respectively fixedly connected to the two plates, and one end of the telescopic plate is in contact with the first rectangular block.

[0009] Preferably, a limiting device is provided at one end of the cover edge close to the turntable, and the limiting device includes a limiting column, one end of the limiting column is slidably connected to the cover edge, a chassis is sleeved on the surface of the limiting column, one end of the chassis close to the cover edge is fixedly connected to a second spring, and one end of the second spring away from the chassis is fixedly connected to the cover edge.

[0010] Preferably, two limiting holes are formed at one end of the turntable close to the cover edge, and the size of the limiting holes matches the size of the limiting posts.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, a protective device is provided, and the two clamping arms are moved toward one end close to each other, so that the clamping arms drive the sliding rod to move into the sleeve barrel. At this time, the two connecting rods drive the first rectangular block and the second rectangular block to move toward each other. At this time, the telescopic plate is pressed so that the fixed plate and the telescopic plate on the second rectangular block pass through the through hole of the first rectangular block, and then the telescopic plate is released so that the spring sheet in the telescopic plate resets the telescopic plate. At this time, one end of the telescopic plate and one end of the rectangular block are in contact with each other. At this time, the protective net is placed in the groove of the side wall of the air vent. At this time, the clamping arm and the groove are in the same straight line, and then the telescopic plate is squeezed so that the telescopic plate is no longer in contact with the first rectangular block. At this time, the two clamping arms are no longer in contact with each other. The manhole cover is fixed so that the first spring rebounds the two clamping arms to their original positions, so that the two clamping arms respectively drive the first rectangular block and the second rectangular block to move with them, so that the clamping arms enter the side wall grooves of the air vents, thereby fixing the protective net and allowing the protective cover to cover the air vents. When the manhole cover needs to be opened, the turntable is rotated so that the air vents on the turntable and the air vents on the manhole cover coincide with each other, thereby opening the manhole covers respectively. This solves the problem that there are often manhole covers on crosswalks, and there are air vents on the surface of the manhole covers, and there are no protective measures for the air vents on the existing manhole covers, resulting in objects such as coins easily falling into the manhole cover through the air vents, and the manhole cover is difficult to open, resulting in the problem that it is difficult to take out the fallen objects.

[0013] 2. In the present invention, a limiting device is provided, and a limiting post in the sliding cover edge is used to make the limiting post leave the limiting hole in the turntable. At this time, the turntable is rotated so that the limiting hole on the turntable and the limiting post are in the same straight line. At this time, the limiting post is released, so that the second spring on the cover edge bounces the bottom plate and the limiting post back to their original position, so that the limiting post enters the limiting hole, thereby fixing the turntable. This solves the problem that the air holes on the turntable and the air holes on the manhole cover cannot be fixed when they coincide with each other. BRIEF DESCRIPTION OF THE DRAWINGS

The first spring 404 is fixedly connected to the protective net 401 at one end away from the clamping arm 405, and the ends of the two clamping arms 405 close to each other are fixedly connected to the connecting rod 406, and the ends of the two connecting rods 406 close to each other are respectively welded with a first rectangular block 407 and a second rectangular block 408, a through hole 411 is provided on the surface of the first rectangular block 407, and the end of the second rectangular block 408 close to the first rectangular block 407 is fixedly connected to a fixed plate 409, and one end of the fixed plate 409 is fixedly connected to a telescopic plate 410, and the telescopic plate 410 is composed of two hollow plates of different sizes, and the surface of the small plate is slidably connected to the inside of the large plate, and the inside of the telescopic plate 410 is provided with a through hole 411.
