Especially in modern cities, with the improvement of municipal facilities and the development of road traffic, more and more manhole covers have appeared, so the safety performance of manhole covers has received more and more attention, and more people are studying in this field. . Among the many safety accidents of manhole covers, the manhole covers drifted away due to rainstorms and floods, causing accidents that people accidentally fell into it is particularly serious.
  • This kind of manhole cover has the following disadvantages: on the one hand, when the manhole cover is washed away, the positioning system cannot enable people to find the manhole cover quickly because it is in water, which not only takes time and effort but also delays the repair progress; on the other hand, the danger of bare wells is lacking The warning function is easy to cause safety accidents, especially at night.
  • the present invention aims to provide a safety manhole cover that can effectively prevent the manhole cover from being washed away when storms and floods come, can fence the wellhead, and has an alarm function.
  • a new type of safety manhole cover with a containment function including a disc-shaped manhole cover body matching the wellhead, and a pressure sensor connected to the control unit on the lower surface of the manhole cover body ,
  • An annular concrete base is provided below the surface of the wellhead, an annular groove is provided on the surface of the base, an annular baffle is provided in the groove, and the bottom of the baffle is fixed on the base by an elastic member
  • the groove is also provided with a groove cover opened by the control unit to cover the groove.
  • the difference between the inner diameter of the groove and the diameter of the body of the manhole cover is 1 cm to 5 cm.
  • the baffle is a telescopic plate.
  • the outer surface of the baffle is coated with waterproof fluorescent paint.
  • a sound alarm is provided on the base, and the alarm is controlled by a control unit.
  • the bottom of the groove is provided with a passage through the base to the shaft.
  • the present invention has the advantage that when the amount of rain in the well is too large, the impact force of rain on the bottom of the manhole cover is sensed by the pressure sensor, and when the threshold value is reached, the slot cover is opened to eject the baffle. It can have a certain stabilizing effect on the manhole cover and prevent it from being washed away by the water flow. On the other hand, it can serve as a warning to pedestrians and prevent people from walking near the manhole cover to cause accidents, especially in protecting the elderly and children. , Has a significant effect; applying fluorescent paint on the baffle can make people easily avoid the wellhead at night; in addition, the invention also has a sound alarm, which can surround the wellhead and alert the surroundings by sound alarm Pedestrians are especially helpful for blind people.
  • Figure 1 is a schematic structural view of the present invention
  • FIG. 2 is a schematic diagram of the present invention when the baffle pops up
  • Figure 3 is a schematic diagram of the present invention.
  • Embodiment 1 is shown in Figures 1 to 3: a new type of safety manhole cover with enclosure function, including a disc-shaped manhole cover body 1 matching the wellhead; the lower surface of the manhole cover body 1 is provided with a control unit 3
  • the pressure sensor 5 can sense the impact force of the water flow on the manhole cover body 1 through the pressure sensor 4; an annular concrete base 2 is provided below the surface around the wellhead, and an annular groove 21 is provided on the surface of the base 2
  • An annular baffle 22 is provided in the groove 21, the bottom of the baffle 22 is fixed on the base 2 by an elastic member, and a groove cover 23 opened by the control unit 3 is also provided on the groove 21 to cover the groove twenty one.
  • the baffle 22 is entirely located in the groove 21 and closed by the slot cover 23.
  • the reason for the manhole cover being washed away is mostly because the impact of the water flow in the hoistway on the lower surface of the manhole cover is too large (when the gravity of the manhole cover is exceeded), so that the manhole cover is gradually washed away and finally drifted away.
  • the principle of the present invention is to use the pressure sensor 4 to detect the impact force of the water flow on the lower surface of the manhole cover body 1. When the impact force reaches a critical value (which may be slightly smaller than the gravity of the manhole cover body), the slot cover 23 is opened by the control unit 3 to cause the baffle 22 to pop out.
  • the surface of the pressure sensor 4 is equipped with a waterproof sealing facility, such as a waterproof sealing film;
  • the critical value of the impact force of the pressure sensor 4 is set (the impact force here is not the buoyancy of the water flow on the manhole cover body 1), and its value is not equal to the manhole cover
  • the gravity of the body 1 should be calculated according to the ratio of the area of the pressure sensor 4 in contact with water to the surface area of the bottom of the manhole cover body 1 (for example: the gravity of the manhole cover body 1 is G, the contact area of the pressure sensor 4 is s, and the bottom of the manhole cover body 1 is in contact with water
  • the effective area is S
  • the critical value of the pressure sensor 4 should be set to (s ⁇ S) ⁇ G).
  • the pressure sensor 4 is also provided with a size equal to the size of the manhole cover body 1 Induction plate, the impact force of the water flow is sensed through the induction plate.
  • the impact force is greater than the sum of the gravity of the manhole cover body 1 and the gravity of the induction plate, the manhole cover body 1 will drift away, and the critical value of the pressure sensor 4 can be set as the manhole cover The sum of the gravity of the body 1 and the gravity of the induction plate.
  • the critical value calculated on this basis is slightly smaller than the theoretical critical value Value (the theoretical critical value is the value when the gravity of the pressure sensor 4 is included), so its safety is higher.
  • the baffle 22 of the present invention has two effects after opening: 1. It has a good stabilizing effect on the manhole cover body 1 and can prevent drifting away. In order to make the effect better, the difference between the inner diameter of the groove 21 and the diameter of the manhole cover body 1 is 1 cm to 5 cm; 2. It has a barrier effect on the wellhead, which can prevent pedestrians from entering the vicinity of the manhole cover body 1, which is particularly dangerous for children or children.
  • the baffle 22 is set as a telescopic plate (the telescopic plate can be set as a multi-layer plate, the inner plate is fixed inside the outer plate by a spring, the top is pressed by the slot cover, the slot cover is opened, After the telescopic panel is ejected, the inner panel is ejected from the outer panel to increase the overall height of the baffle).
  • the height after the extension is about 0.5m, so that the height of the enclosure can be increased, which is easier for people to see and further improve safety.
  • the outer surface of the baffle 22 is coated with a waterproof fluorescent paint, and the fluorescent paint can also be written as "water well danger", “here is dangerous”, "please stay away from the wellhead” and other words to remind people.
  • the bottom of the groove 21 is provided with a passage 24 passing through the base 2 to the shaft. After the rainwater recedes, the water in the groove can be drained through the channel 24 to prevent the long-term retention of water from eroding the groove and improve the service life.
  • the principle of the invention is simple, all structures and components are common components, low cost, easy installation and maintenance, while protecting the manhole cover, it can intuitively remind people of the danger of the wellhead, has good practicality, and is worthy of widespread promotion use.
  • a sound alarm 5 is provided on the base 2, and the alarm is controlled by the control unit 3.
  • the audible alarm 5 can be activated through the control unit 3 at the same time as the baffle 22 is activated, and the pedestrian can be reminded by sound, especially for the blind.
  • the slot cover When the amount of rain in the well is too large, the impact force of the rain on the bottom of the manhole cover is sensed by the pressure sensor. When the threshold value is reached, the slot cover is opened to eject the baffle. Washed away by the water, on the other hand, it can serve as a warning to pedestrians and prevent people from walking near the manhole cover to cause accidents, especially in protecting the elderly and children. It has a significant effect; painted on the baffle The fluorescent paint can make people easily avoid the wellhead at night; in addition, the invention also has a sound alarm, which can surround the wellhead and warn pedestrians by sound alarm, especially for the blind.
