Abstract
The invention discloses a backflow well lid which comprises a well seat and a well lid body. The well lid body comprises an upper cover plate and a lower cover plate; the outer circular surface of the lower cover plate is matched with the inner circular surface of the well seat; the upper cover plate is in contact and fit with the upper surface of the well seat; a plurality of counter bores are formed in the well lid body; the height of a large hole of each counter bore is larger than the distance between the lower end face of the well lid body and the upper end face of the well seat after the well lid body is installed; a threaded rod is arranged in each counter bore; the lower end of each threaded rod is connected with the well seat in a thread fit mode; a supporting plate of a net structure is arranged between the lower cover plate and the well seat. By means of the well lid, a person can be effectively prevented from falling into a well.
Description
Technical field
The present invention relates to well lid technical field, pour in down a chimney well lid in particular to one.
Background technology
In city, all kinds of city planting ductwork is crisscross, road is also a mass of the active well of all kinds of city planting ductwork, the situation of pouring in down a chimney easily is produced when rainwater or the larger situation of surface drainage amount, and existing well lid is many times when pouring in down a chimney, can be flushed away or be shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property.
Summary of the invention
One is the object of the present invention is to provide to pour in down a chimney well lid, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
One pours in down a chimney well lid, comprises well seat and well lid, it is characterized in that, described well lid is upper and lower cover plates, and the periphery of lower cover matches with the inner headed face of well seat, and upper cover plate contacts with well seat upper surface and coordinates; Described well lid is provided with multiple counter sink, and the macropore height of counter sink is greater than well lid and installs the distance of rear well lid lower surface to well seat upper surface; Be provided with screw rod in described counter sink, screw rod lower end is connected with well seat threaded engagement; Be provided with gripper shoe between described lower cover and well seat, gripper shoe is net structure.
Further, the multiple counter sinks on described well lid are uniformly distributed.
The invention has the beneficial effects as follows,
When the rainwater in well pours in down a chimney, due to screw rod and well seat threaded engagement, well lid is moved up along screw rod, and after the lower cover of well lid exceeds well seat, rainwater starts to discharge, after the rainwater in well no longer pours in down a chimney, well lid, under self gravitation effect, covers well seat along screw rod, thus after effectively avoiding well lid to be flushed away or being shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property.
In addition, after well lid is by breakage, gripper shoe can be blocked the people fallen and wait object, and compared with prior art, well lid of the present invention can effectively prevent people etc. from crashing in well, avoids injures and deaths and property loss etc.; Also there is the structural strength strengthening well lid simultaneously, avoid being damaged by pressure distortion in well lid use procedure and impact uses.
Accompanying drawing explanation
Fig. 1 is the structural representation pouring in down a chimney well lid provided by the invention.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Fig. 1 is shown, and one provided by the invention pours in down a chimney well lid, comprising: well seat 1, well lid 2, upper cover plate 21, lower cover 22, screw rod 3 and gripper shoe 4.Described well lid 2 is upper and lower cover plates, and the periphery of lower cover 22 matches with the inner headed face of well seat 1, and upper cover plate 21 contacts with well seat 1 upper surface and coordinates; Described well lid 2 is provided with multiple counter sink, and the macropore height of counter sink is greater than well lid 2 and installs the distance of rear well lid 2 lower surface to well seat 1 upper surface; Be provided with screw rod 3 in described counter sink, screw rod 3 lower end is connected with well seat threaded engagement; Be provided with gripper shoe 4 between described lower cover 22 and well seat 1, gripper shoe 4 is in net structure; Multiple counter sinks on described well lid 2 are uniformly distributed.
When the rainwater in well pours in down a chimney, due to screw rod 3 and well seat 1 threaded engagement, well lid 2 is moved up along screw rod 3, and after the lower cover 22 of well lid 2 exceeds well seat 1, rainwater starts to discharge, after the rainwater in well no longer pours in down a chimney, well lid 2, under self gravitation effect, covers well seat 1 along screw rod 3, thus after effectively avoiding well lid 2 to be flushed away or being shifted, vehicle and personnel easily drop to down-hole, cause the loss of the person and property
After well lid 2 is by breakage, gripper shoe 4 can be blocked the people fallen and wait object, and compared with prior art, well lid 2 of the present invention can effectively prevent people etc. from crashing in well, avoids injures and deaths and property loss etc.; Also there is the structural strength strengthening well lid 2 simultaneously, avoid being damaged by pressure distortion in well lid 2 use procedure and impact uses.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
