Opening and closing device for vertical wastewater wellhead and combination method of the same and wastewater well horizontal with ground

Abstract

The invention relates to an opening and closing device for a vertical wastewater wellhead. The wellhead is sealed by using a waterproof material; once water is collected at the wellhead, the water rises a floating object arranged outside a well above a water surface; the floating object is tied with a rope and can reach the back of the material for sealing the wellhead through the conveying effect of the rope so that the material for sealing the wellhead can automatically open; when the water completely retreats into the well, the floating object drops along with the water, the rope relaxes, the self weight of the material for sealing the wellhead drops, the opening and closing device automatically closes, the completion of the functions of the whole set of device is completely determined by the water collected outside the wellhead without needing to apply artificial conditions to the device; and a combination method of the opening and closing device and the wastewater well horizontal with the ground is characterized in that the opening and closing devices at different directions are arranged in the wastewater well horizontal with the ground next to the lower side of an iron grate; when the wastewater well horizontal with the ground is full of sewage, the wastewater outside the well still can seep into the well through the unfilled sewage, and the wastewater seeping into the well enables the opening and closing devices at different directions to automatically open; and therefore, the wastewater well horizontal with the ground can not turn into an abandoned well.

Description

technical field [0001] The invention relates to the initial facilities of underground sewage discharge engineering. Background technique [0002] Underground sewage discharge engineering facilities mainly include: drainage outlets, drainage pipes, drop wells, sedimentation wells, drainage inspection wells, sewage collection wells, rainwater collection wells, etc. Sewage drainage projects are the only lifeblood related to urban life, and this lifeblood can be controlled The city has all the benefits, therefore, the more and more perfect the methods of healing this lifeblood, the longer the life expectancy of the city for people's survival, and the lower the probability of failure. [0003] I applied for a patent in this area in 2009. Today, when I was writing the application for the implementation plan, I found that the patent still has imperfections. This time I re-apply to make up for the defects of the original patent. [0004] The original patent only designed the recove...

Problems solved by technology

[0004] The original patent only designed the recovery of waste in the sewage well, and did not consider that the waste well will be formed as the space in the well is limited to the absorption of waste. Once the well becomes waste, there will be strong destructive power inside and outside the well. In order to avoid the appearance of waste wells , I have newly designed an opening and closing device for vertical wellheads. This device can also be used in sewage wells on the ground to increase the service life of sewage wells and prevent them from becoming waste wells. It is easy to find the situation in sewage wells and repair them in time.
