Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific drawings.

[0022] Such as figure 1 , figure 2 with image 3 As shown, a new wellhead device includes a well cover 1, a cover seat 2 and a well shaft 3. The material of the well cover 1 can be metal, plastic, cement concrete or composite materials, etc. The material of the cover seat 2 is generally cement concrete or composite materials. ; The well shaft 3 is provided with a cover seat 2, and the well cover 1 is installed on the cover seat 2. The cover seat 2 is an L-shaped ring in section, including a vertical boss 4 and a horizontal support platform 5. Four gaps 6 are arranged in an array on the platform 4, and the four gaps 6 are evenly and symmetrically arranged. As the starting point for opening the well cover 1, two adults can easily open or place the well cover 1. At the same time, the four gaps 6 provide a good barrier for removing bad gas in the well. Sufficient space; the we...

Abstract

The invention relates to a novel well head device. The novel well head device comprises a well cover, a cover base and a wellbore. The cover base is arranged on the wellbore. The well cover is mountedon the cover base. The cover base is a circular ring with the L-shaped section and comprises a vertical boss and a transverse supporting platform. A plurality of notches are arrayed on the boss. Thewell cover is shaped like a basin and comprises a basin body and a basin edge. The basin body goes deep downwards into the cover base and the wellbore. The basin edge is erected on the well cover. Theportion, corresponding to the notches, of the interior of the basin edge of the well cover is provided with air holes used for discharging bad gas in a well. The bottom of the basin body is providedwith a drain hole. Through the novel well head device, the defects that an existing well cover occupies a land for greening and air holes are blocked easily and are not likely to be opened are changed.

Description

technical field [0001] The invention relates to a novel wellhead device, which belongs to the field of municipal engineering. Background technique [0002] At present, the manhole covers in the green areas such as roads, parks, and residential areas are basically cement concrete manhole covers, plastic manhole covers or composite material manhole covers. The existing manhole covers are bare and scattered on the grass, which is very ugly and seriously affects the landscape. For the green belt with many manhole covers, it not only causes visual pollution, but also takes up valuable green land; the existing manhole cover has only one air hole and is vertical. Located above the well cover, it is easy to block the air holes, causing harmful gases in the well to not be discharged in time. After a large amount of flammable and explosive gas accumulates, it is easy to cause vicious events such as explosions, directly affecting the safety of surrounding personnel and buildings; All ...
