Description

[Detailed explanation of the invention] This invention is a monitoring system that is installed in factory drainage canals, sewage channels, etc., and is used to block manholes and underground structures that are used for the purpose of monitoring the distribution status of wastewater, etc., and the circulating materials while being closed. Regarding iron lids.

In the past, there were no iron lids with a special monitoring iron lid structure, and it was simply a matter of opening the regular iron lid and checking the drainage status inside.

Therefore, it has the disadvantage that it is not possible to monitor the state of flow of waste water or the flow of materials with the iron lid closed.

This project was developed by researching the above-mentioned drawbacks of the conventional structure of the iron lid, and completed a new structure of the monitoring iron lid to solve these problems.The purpose of this project is to The object of the present invention is to provide a monitoring iron lid that allows for reliable and clear internal monitoring even when the lid is closed due to a structure for removing deposits on the lower surface.

Next, the iron lid of the present invention will be described in detail below with reference to embodiments shown in the drawings.

First, the structure will be explained using the example shown in FIGS. 1 to 5. A monitoring window 2 made of two sheets of transparent tempered glass is fitted into a circular iron lid 1, and the window 2 is held by a holding plate. 5, a wiper 3 for removing deposits is pressed against the lower surface of the monitoring window 2 using spring force, and the wiper 3 and the iron cover 1 are supported on the lower protruding frame 1a for reciprocating rotation. A wiper operating handle 4 is connected to a shaft 6 by a wiper arm 7, and a wiper operating handle 4 is provided on the rotary shaft 6 and recessed into the recessed part 1b on the upper surface of the iron lid 1, and the handle 4 is formed to be able to be moved up and down. As shown in FIGS. 3 and 5, the removable structure has a guide groove 6a formed in the reciprocating rotation shaft 6 and a protrusion 4a provided in the wiper operating handle 4, which fit vertically and slidably. This is what I did.

In the figure, 9 indicates the receiving frame, and 10 indicates the receiving frame 9 and the iron lid 1.
11 is a crowbar hole for opening and closing the lid, 12 is a mud guard rubber, 13 is a bearing, and lb' is a recessed part for inserting a finger.

The above has been explained using examples illustrating the iron lid of the present invention, but the shape of the iron lid 1 and the shape and number of transparent tempered glass that is the monitoring window 2 are not limited to the examples, and various shapes can be used. Even if it is a single glass structure, it is included in this proposal.

Therefore, when installing the proposed iron lid on a factory drainage channel or sewage channel, etc., and trying to monitor the distribution status of wastewater etc. and the circulating materials,
If there is mud or other deposits on the top surface of the monitoring window 2, it can be wiped off with a cloth, or if there is water vapor or fluid gas adhering to the bottom surface of the monitoring window 2 in a cloudy state, or dirt or dust is adhering to the bottom surface of the monitoring window 2. If the wiper operating handle 4 is obstructed from monitoring from above, the attached material can be removed simply by grasping the wiper operating handle 4 and rotating it back and forth.

That is, when the wiper operating handle 4 is grasped and rotated back and forth, the wiper 3 is rotated back and forth while being in pressure contact with the lower surface of the monitoring window 2, as shown in FIG.
The deposits within the range of pressure movement are removed in an orderly manner.

As mentioned above, the deposits on the bottom surface of the monitoring window 2 can be removed by operating from the second side of the iron lid 1, so even if the bottom surface of the monitoring window 2 has deposits that obstruct visibility, it can be closed. Not only is it reliable as it is, but it also allows for clear internal monitoring.

Since the iron cover of the present invention can be constructed and used as described above, it has the effect of being able to remove the deposits on the bottom surface of the monitoring window 2 in an orderly manner, and this removal effect ensures that it remains closed and remains closed. It also achieves the effect of clear internal monitoring.

In addition, the wiper operating handle 4 is attached to the concave portion 1 on two sides of the iron lid 1.
Since it is formed so that it can be taken out and stored from b, there is also the advantage that the wiper operating handle 4 does not get in the way of traffic.
