Abstract

The invention relates to the field of public facilities, and particularly discloses a safe sewer manhole. The safe sewer manhole comprises a manhole wall and a manhole cover, a circle of evenly distributed spring pieces are arranged on the manhole wall, the lower ends of the spring pieces are fixed on the manhole wall, the upper ends of the spring pieces are each shaped like a T, the back face of the manhole cover is provided with evenly distributed convex grooves of which the number is the same as that of the spring pieces, the convex grooves are formed in the radius direction of the manhole cover, and one side of each convex groove is provided with a notch which can allow the T-shaped end of the corresponding spring piece to pass through. When rainwater is too much in a sewer, due to the fact that the sewer does not have enough time to discharge flood, the rainwater can jack up the manhole cover upwards, at this time, due to the fact that the pressure is reduced, the spring pieces are rebounded, the T-shaped ends of the spring pieces slide from inside to outside in the convex grooves, therefore, the manhole cover is pressed against the upper portion of the manhole mouth and can not be washed away, and damage to pedestrians is avoided; when maintenance is conducted, a person only needs to lift up the manhole cover, and when the T-shaped ends slide to the notches, the person slightly rotates the manhole cover to make the T-shaped ends located in the notches so as to take down the manhole cover very conveniently.

Description

A kind of safe water drain well

(1) technical field

The present invention relates to urban operating mechanism field, particularly a kind of safe water drain well.

(2) background technology

Modern city well cover for sewer is lost serious, is stolen on the one hand, and run into Severe rainstorm weather on the other hand and be flushed away, the sewer well casualty accident opened happens occasionally, and causes great threat to civic personal safety.

(3) summary of the invention

The present invention, in order to make up the defect of prior art, provides a kind of pedestrian of preventing and falls in sewer the safe water drain well causing casualty accident to occur.

The present invention is achieved through the following technical solutions:

A kind of safe water drain well, comprise the borehole wall and well lid, it is characterized in that: the described borehole wall is provided with the uniform spring leaf of a circle, the lower end of described spring leaf is fixed on the borehole wall, upper end is in T shape, and the described well lid back side is provided with the quantity uniform convex slot equal with spring leaf, and described convex slot is arranged along the radial direction of well lid, the side of described convex slot is provided with a gap, and the T-shaped end that described gap can hold spring leaf passes through.

The lower end of described spring leaf is provided with an axle vertical with the longitudinal direction of spring leaf, and on axle, cover has spring, and the two ends of spring are attached on the spring leaf of axle both sides respectively.

Described gap is positioned at 5 ~ 10cm place, outer end of distance convex slot.

The invention has the beneficial effects as follows:

When in sewer, rainwater is too many, because sewer has little time flood discharge, rainwater will by well lid upwards jack-up, now due to pressure relieve, spring leaf rebounds, just slide from inside to outside in its T-shaped one end in convex slot, such well lid just can not be flushed away by withstanding on the top of well head, also just avoids the injury to pedestrian; During maintenance, only well lid need be mentioned, when T-shaped one end slides into opening position, rotated a little by well lid and be positioned at gap to T-shaped end, well lid has just been lifted down, very convenient.

(4) accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further illustrated.

Fig. 1 is decomposition of the present invention, sectional structure schematic diagram;

Fig. 2 is the main TV structure schematic diagram at the back side of well lid;

Fig. 3 is the cross section structure schematic diagram of convex slot.

In figure, 1 borehole wall, 2 well lids, 3 spring leafs, 4 otic placodes, 5 axles, 6 springs, 7 convex slots, 8 gap.

(5) detailed description of the invention

Accompanying drawing is specific embodiments of the invention.As shown in Figure 1 to Figure 3, this kind of safe water drain well, comprise the borehole wall 1 and well lid 2, the borehole wall 1 is provided with four pieces of spring leafs 3, these four pieces of spring leafs 3 are evenly arranged along the axis of the borehole wall 1, their upper end is in T shape, lower end is fixed on the borehole wall 1, an otic placode 4 being with circular hole is respectively had in the both sides, lower end of spring leaf 3, an axle 5 is installed with between two otic placodes 4, on axle 5, cover has a spring 6, two sections of spring 6 stretch out and are attached on the spring leaf of axle 5 upper end and the spring leaf of lower end or the borehole wall 1 respectively afterwards, four uniform convex slots 7 are provided with at well lid 2 back side, the chamber portion in the cross section of these convex slots 7 is convex shape, these convex slots 7 are arranged along the radial direction of well lid, the side of convex slot 7 is provided with a gap 8, this gap 8 is that 5 ~ 10cm is advisable apart from the outer end of convex slot, the T-shaped end that its length and width should be able to hold spring leaf 3 passes through.

Under normal circumstances, when well lid 2 covers on well head, spring leaf 3 is bent, when running into the water row of sewer not in time, by jack-up under the double action of the water of well lid 2 in sewer and spring leaf 3, slide in T-shaped one end of spring leaf 3 in convex slot 7, the top making well lid 2 be positioned at well head can not be flushed away, and pedestrian also would not be had to drop in sewer thus damaged; During maintenance, only well lid need be mentioned, when T-shaped one end slides into opening position, rotated a little by well lid and be positioned at gap to T-shaped end, well lid has come with regard to those, very convenient.

Except technical characteristic described in manual, all the other technical characteristics are those skilled in the art's known technology.
