Abstract
The invention discloses a well lid key opening plugging device. The well lid key opening plugging device is characterized in that a plugging piece, a connecting rod and two spring pieces are included, the connecting rod and the plugging piece are vertically and fixedly connected together, one end of each spring piece is fixedly connected with the connecting rod, the other end of each spring piece is matched with the plugging piece, the two spring pieces are placed in the same plane which is perpendicular to the plugging piece, and the two spring pieces and the connecting rod can be put in and penetrated out from a key opening. In the using process, the connecting rod and the spring pieces of the plugging device are partially inserted into the key opening to be rotated, the spring pieces and the plugging piece are made to clamp a lid body of a well lid, and then the plugging piece can plug the key opening. When the well lid needs to be opened, the plugging piece is rotated before a key is inserted in so that the spring pieces and the connecting rod can be taken out smoothly from the key opening. The well lid key opening plugging device is simple and convenient to open, lowers the working risk of maintainers and improves the working efficiency.
Description
Technical field
The present invention relates to the gas valve well cover in combustion gas corollary equipment field, specifically a kind of well cover key mouth plugging device.
Background technology
Gas valve well cover is provided with and can inserts the key operated and key mouth locking well lid, due to most burnt gas valve wells all in open space, be subject to the impact of the factors such as natural environment and mankind's activity environment, key mouth on well lid is often by foreign matter shutoff such as handstone or silts, can't insert smoothly key, causing can't open manhole cover.Cleaning key mouth need to beat foreign matter with a word bottle opener and iron hammer, remove clean plug, this method for cleaning very easily produces spark in the process of knocking, for avoiding pipeline gas leakage to run into the issuable explosion accident of spark, scale removal process can only slowly and carefully be carried out, have certain hazards, and workload is large, expends time in longer.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, and provide a kind of, can prevent that the key mouth is by the well cover key mouth plugging device of foreign matter shutoff, it is simple, convenient that this plugging device is opened, and reduces maintainer's work risk, increases work efficiency.
The objective of the invention is to realize by following technical scheme:
A kind of well cover key mouth plugging device, comprise plugging sheet, connecting rod and two spring leafs, described connecting rod is vertical with plugging sheet to fix as one, one end and the connecting rod of spring leaf are affixed, the other end matches with plugging sheet, two spring leafs are on the same plane vertical with plugging sheet, and two spring leafs and connecting rod can be put into, pass from the key mouth.
During use, by the connecting rod of this plugging device and spring leaf partial insertion key mouth, integral-rotation, make spring leaf and plugging sheet clamp the lid on well cover key mouth side, and plugging sheet is about to the shutoff of key mouth.While opening well lid, before inserting key, by the plugging sheet rotation, make spring leaf and connecting rod successfully from the key mouth, take out and get final product.
It is simple, convenient that this plugging device is opened, and reduced maintainer's work risk, improved operating efficiency.
The accompanying drawing explanation
The structural representation that Fig. 1 is the embodiment of the present invention;
Fig. 2 is plugging device and the equipped structural representation of key mouth in embodiment.
In figure, 1. plugging sheet 2. spring leaf 3. connecting rod 4. key mouth 5. lid 6. cover lock carriages.
The specific embodiment
Below in conjunction with drawings and Examples, content of the present invention is further elaborated, but is not limitation of the invention.
Embodiment:
With reference to Fig. 1, a kind of well cover key mouth plugging device, comprise plugging sheet 1, connecting rod 3 and two spring leafs 2, described connecting rod 3 fixes as one with plugging sheet 1 is vertical, one end and the connecting rod 3 of spring leaf 2 are affixed, the other end matches with plugging sheet 1, and two spring leafs 2 are on the same plane vertical with plugging sheet 1, and two spring leafs 2 can be put into, pass from key mouth 4 with connecting rod 3.
With reference to Fig. 2, during use, by in the connecting rod of this plugging device 3 and spring leaf 2 partial insertion key mouths 4, connecting rod 3 one ends insert in the hole of cover lock carriage 6, rotation, make spring leaf 2 and plugging sheet 1 clamp well lid lid 5, plugging sheet 1 is about to 4 shutoff of key mouth, Figure 2 shows that spring leaf 2 and the long end of key mouth 4 are 90 °.While opening well lid, before inserting key, by plugging sheet 1 rotation, make spring leaf 2 and connecting rod 3 successfully from key mouth 4, take out and get final product.
