Description

Security fence for hydraulic and hydroelectric engineering

Technical Field

The utility model relates to a water conservancy water and electricity field, concretely relates to security fence for hydraulic and hydroelectric engineering.

Background

Hydraulic and hydroelectric engineering facilities include various machine rooms, power distribution rooms, transformer substations and the like, and in order to protect the facilities, safety fences are generally required to be additionally arranged outside the engineering facilities. The safety fence has the functions of preventing illegal persons, wild animals and the like from invading, and also has the functions of preventing falling rocks and the like. Most of areas with developed hydraulic resources are concentrated in mountainous areas, but the mountainous areas are also areas with multiple occurrence of debris flow, collapse and the like, and when the existing safety fence faces natural disasters such as rock rolling, local collapse and the like, the protection performance of engineering facilities is poor, the engineering facilities are damaged, and the production and life order is seriously influenced.

Disclosure of Invention

An object of the utility model is to provide a security fence for hydroelectric engineering with high barrier propterty.

In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: a safety fence for water conservancy and hydropower engineering comprises a plurality of upright rod units arranged side by side and a plurality of cross rods used for connecting the upright rod units;

the pole setting unit includes the base and sets up outer pole setting and interior pole setting on the base, the lower extreme of outer pole setting and interior pole setting all welds with the base, and the upper segment of outer pole setting and interior pole setting is close to and inwards arc bending constitutes falling stone guard area, and the hypomere of outer pole setting is the arc and outwards bulges and constitutes the rubble buffer zone.

Preferably, the inner vertical rod and the outer vertical rod are formed by bending the same steel bar.

Preferably, the base is fixed to the ground by means of an anchor rod.

Preferably, the inner side of the base is provided with a side wing plate, an inclined strut is arranged between the lower section of the inner vertical rod and the side wing plate, and two ends of the inclined strut are respectively welded with the inner vertical rod and the side wing plate.

Preferably, the horizontal pole is provided with 4 from top to bottom, the horizontal pole welds with interior pole setting.

Preferably, the bottom end of the anchor rod is provided with an anti-return hook.

The beneficial effects of the utility model are concentrated and are embodied in: can effectually protect falling rocks and rolling stones, avoid engineering facility to suffer destruction, stability is fabulous. Particularly, the utility model discloses a falling rocks guard zone can block falling rocks, flying rocks etc. and curved structure also has fabulous shock-absorbing capacity. Because the rolling stones generated by natural disasters such as earthquake, landslide and the like contact with the rolling stone buffer area firstly when contacting with the fence, and the rolling stone buffer area absorbs the energy carried by the rolling stones in a collapsing energy absorption mode, so that the destructive influence of the rolling stones on the fence or internal engineering facilities can be effectively prevented. The utility model discloses the diagonal brace of preferred setting can play further additional strengthening to the internal pole setting, thereby further promotes the utility model discloses a barrier propterty.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The safety fence for water conservancy and hydropower engineering shown in fig. 1 comprises a plurality of upright rod units arranged side by side and a plurality of cross rods 1 used for connecting the upright rod units. The spacing distance between the upright units is usually 10-20CM, and the usage amount is designed according to the enclosure protection of the engineering facility, and the cross rod 1 is used for connecting each upright unit on one hand and uniformly distributing stress to each upright unit on the other hand.

The pole setting unit includes base 2 and sets up outer pole setting 3 and interior pole setting 4 on base 2, base 2 passes through stock 7 to be fixed subaerial, and the length that stock 7 stretched into the soil layer is longer more, and anchorage nature is better, and it stretches into length and is not less than half a meter usually. In order to make the installation of the base 2 more stable, the bottom end of the anchor rod 7 may be provided with an anti-back hook 10, and the anchor rod 7 is prevented from being withdrawn from the soil layer by the anti-back hook 10.

The inboard of base 2 is provided with flank board 8, be provided with diagonal brace 9 between hypomere and the flank board 8 of interior pole setting 4, diagonal brace 9's both ends weld with interior pole setting 4 and flank board 8 respectively. Diagonal brace 9 can carry out further enhancement support to internal pole setting 4, improves the utility model discloses a whole shock resistance.

The lower extreme of outer pole setting 3 and interior pole setting 4 all with base 2 welding, the upper segment of outer pole setting 3 and interior pole setting 4 is close to and inwards arc bending constitutes falling rocks guard zone 5, and outer pole setting 3 and interior pole setting 4 form bilayer structure's falling rocks guard zone 5 jointly, can effectually resist the impact of general miniature falling rocks. The utility model discloses outer pole setting 3's hypomere is the arc and constitutes the roll stone buffers 6 to the protrusion outwards, because the general relative stone that falls of the volume of roll stone is bigger, the mode that adopts the rigidity to block alone intercepts its effect not good to the roll stone, so the utility model discloses a mode of collapsing the energy absorption cushions the roll stone.

When rolling stones generated by natural disasters such as earthquakes, landslides and the like contact the fence, the rolling stones are firstly contacted with the rolling stone buffer area 6, and the rolling stone buffer area 6 absorbs energy carried by the rolling stones in a collapse energy absorption mode, so that destructive influence on the fence or internal engineering facilities caused by the rolling stones can be effectively prevented.

Interior pole setting 4 and outer pole setting 3 all generally adopt just making, of course, adopt the iron pole setting also to be totally feasible. In order to improve the connection firmness of the upper ends of the inner vertical rod 4 and the outer vertical rod 3, the inner vertical rod 4 and the outer vertical rod 3 are preferably formed by bending the same steel bar, and the two are directly connected to form a whole, so that the structural strength is higher.

As shown in the drawing, horizontal pole 1 is provided with 4 from top to bottom, horizontal pole 1 welds with interior pole setting 4. Of course, the number of the cross bars 1 can also be increased reasonably according to the height of the pole unit.
