Description

  The present invention relates to a sewage bottle lid removal prevention device and a sewage bottle lid provided with a sewage bottle removal device.

  The sewage tank is usually closed with a concrete lid. However, since a hole for inserting a bar or the like for opening the lid is formed, it can be opened and closed by a person other than the person in charge. Incidentally, when a universal sewage basin concrete cover is shown in FIG. 6, a lid hole 11 is drilled in the lid 1.

  Therefore, if the lid is opened or shifted by a person other than the person in charge, there is a risk that a fall, a fall accident, or the like will occur.

  In order to prevent the lid from being opened, for example, it is conceivable to seal the existing hole of the lid by sticking a seal, but it may be conspicuous and intriguing.

  In order to solve these problems, several proposals have recently been proposed, for example, Patent Document 1 proposes a manhole iron lid plug structure and Patent Document 2 proposes an iron lid fistula plug.

From the back side of the lid 1, a sewage jar lid removal prevention device comprising a lid portion mounting plate 2, a closing plate 3 and a rotating shaft 4 is provided. The attached state is shown.

  FIG. 2 is a perspective view seen from the back side of the lid mounting plate 2, and FIG. 3 is a perspective view seen from the back side of the closing plate 3 coupled with the rotating shaft.

  The lid mounting plate 2 is larger than the lid hole 1a of the lid 1 in length and width on a circular steel plate 2 attached to the back surface of the lid 1 shown in FIG. The notch hole 2b of the size is provided, the length of the notch hole 2b is sandwiched between the back surface of the plate body 2a, and the crank-shaped holding metal fittings 5 are provided on both sides thereof in directions in which the respective openings 5a are opposite to each other. It is fixed by bonding, welding, screws or the like.

  The closing plate 3 is made of steel, and includes a plate body 3a that covers the notch hole 2b of the lid mounting plate 2 and that is positioned between the holding brackets 5 and 5, and the rotary shaft 4 is disposed on the outer periphery. It consists of a bolt-shaped object with threaded 4a, and is provided with rod-shaped fixed wings 6 penetrating the rotating shaft 4 in both directions perpendicular to the axis, and a rotating means 4a such as a hexagon socket for a driver as shown in FIG. It is equipped with.

  The closing plate 3 has an insertion hole through which the rotation shaft 4 is inserted, and the closing plate 3 and the rotation shaft 4 are inserted from the back surface of the closing plate 3 and the rotation shaft 4 is inserted from the head. Connect by screwing or inserting. In this embodiment, the both sides of the closing plate 3 are sandwiched between flanges 4b and 4c formed on the rotation shaft.
