Definitions

  • Volatile gases are emitted from the cover of another manhole, especially if it may be infected or directly carried by other animals in the sewer. This kind of transmission may also be very serious. Now it is promoted everywhere to wear masks, wash hands frequently, and gather less to avoid infection. Wuhan, the epicenter of the epidemic, uses spray cannons to kill on the street, but the waste water from washing our hands, urination and defecation, there is the virus. Killed it?
  • the present invention proposes some improved structures for manhole covers that can not only ensure rapid drainage but also prevent gas and biological back overflow. It is characterized by the addition of an anti-overflow top pillar structure to control the opening and closing of the funnel drainage channel, and it is automatically realized based on the interaction between the gravity principle of the flow difference and the elastic force and buoyancy. It is composed of an upper cover plate with a grate and a top column, an upper edge and a lower funnel with a spring. The upper edge is fixed on the upper cover plate. Push into the drain hole of the lower funnel; it can also be composed of an upper cover with a grate and a long funnel with an overflow window and a built-in ring valve with a float.

  • the lower funnel slowly shrinks upwards and slowly closes with the upper edge or the upper cover.
  • the water is mainly discharged from the drain hole of the lower funnel, and the current funnel When there is little water, the top column is slowly inserted into the hole of the lower funnel until it returns to an anhydrous state.

  • the spring can also be installed vertically, but consider trying not to keep it in contact with water frequently. Although the current stainless steel spring is not afraid of water, the sundries in the water will affect the spring. It is gratifying that I also came up with another structure that does not use springs, a buoyancy reset structure that Archimedes could implement more than 2,000 years ago.
  • the upper cover plate and the long funnel 6 shown in Figure 1 are directly screwed together, but the ring valve with the conical float shown in Figure 3 should be installed before installation. Just fit the cone 7-1 tip directly to the hole of 6-2.
  • the long funnel 6 is screw-mounted with the 4-2 additional mounting platform as shown in the upper edge of Fig. 1 and the upper cover plate.
  • stainless steel is widely used now. Copper and electroplating are traditional. Urban sewers are not demanding. I think tinplate can be used.
  • the distance between 7-1 and 8 is exactly equal to the distance between 6-2 and 6-1. Therefore, when the tip of the cone float is pushed into the hole of 6-2, the circle shape represented by 8 The valve just closes the overflow window of 6-1.
  • the diameter of the ring valve is equal to the inner longitude of the long funnel 6.
  • the tapered float 7 should be hollow, for example made of stainless steel. Of course, the float and ring valve can all adopt other shapes. Reasonably adjust the size of the 6-2 hole and the width of the ring valve so that the 6-1 will only open when the drainage flow reaches a certain value.

  • the embodiments of the present invention are all circular funnels, based on the same principle, wedge shapes are of course also possible, and spherical, triangular pyramids, quadrangular pyramids, etc. are also possible. Because many manhole covers are still square, the connection of the square manhole covers should of course be a quadrangular pyramid.
  • the float of the present invention can also have similar shapes that can be matched with these shapes, that is, the top of the float must be just pushed into the drain hole of the funnel to prevent the back overflow of gas and organisms. Just pay attention to the difference between the taper of the float and the taper of the funnel. Otherwise, how can the water reach the top of the float and float the float from the bottom? Of course, to meet the design requirements, it is economical and applicable.

Install an air conditioning fan that many people use in summer in a manhole that is easy to manage or take care of, and add a suitable concentration of 84 disinfectant to its water tank.
  • the equipment is specially designed for humidification, dust removal, and sterilization. It can be used to deal with sandstorms. It can be used for dust removal and SO 2 reduction in coal-fired power plants.
  • I also give a convenient management structure, which is to use a large carton or metal box to cover the manhole cover, and put the air-conditioning fan or heavy rain curtain airflow window in the box, and open the air outlet of the air-conditioning fan in the same way as the air-conditioning fan.
  • the air outlet of the air conditioner fan faces the opening of the outer cover box.
  • the box has no bottom, and the bottom side is in direct contact with the ground. It is required to use engineering glue or cement to seal and stabilize. It is best to add a large cover on the top of the box to prevent rain. In this way, not only can the gas inside the sewage pipe be discharged, but also the discharged gas can be strictly disinfected.
  • a blower can be used to blow air into the pipe from another sewage well that is a certain distance away from the exhaust well. In this way, even if the effect of removing the virus gas is not considered, the removal of the biogas in the sewage pipe is also effective. The aforementioned incident of children throwing light firecrackers from the manhole cover into the inside and being blown up can be avoided. In fact, it can be used alone in various hospitals, wards, crowded places, and homes. This method of air conditioning fans and 84 disinfectant that has been used for more than ten years can be used to disinfect and purify the air. Hospital for patients with highly contagious new coronavirus pneumonia. Of course, the effect of making "Heavy Rain Curtain Wind Flow Window" is even better!
