Example Embodiment

[0021] The present invention is described in conjunction with accompanying drawing and specific embodiment:

[0022] like figure 1 shown, and refer to figure 2 , a wall orifice wave absorber, the wall orifice wave absorber includes a wave absorbing orifice 1, a support rod 2 and a guide rail 8; the wave absorbing orifice 1 is vertically arranged and can be turned over relative to the wall The wave-suppressing orifice 1 is hinged with the wave-suppressor fixing assembly fixed on the wall of the underground passage through the orifice fixing hinge 3; one end of the support rod 2 is hinged with the wave-suppression orifice 1 through the support rod fixing hinge 4 , the other end of the support rod 2 is hinged with the slider 5 arranged on the guide rail 8, so that the support rod 2 can move along the guide rail 8 with the slider 5, and drives the wave-dissipating orifice plate 1 to turn over; To limit the front positioning block 7 and the rear positioning block 6 of the moving...

Abstract

The invention belongs to the technical field of the explosion safety protection of an underground passage and provides a wall surface orifice plate wave absorber. The wave absorber comprises a wave absorbing orifice plate (1), a supporting rod (2) and a guide rod (8); the wave absorbing orifice plate (1) is hinged with a wave absorber fixed assembly on the wall surface of the underground passage by an orifice plate fixed pin; one end of the supporting rod (2) is hinged with the wave absorbing orifice plate (1) by a supporting rod fixed pin (4) and the other end of the supporting rod (2) is hinged with a sliding block (5) arranged on the guide rail (8); and the guide rail (8) is provided with a front positioning stop (7) and a rear positioning stop (6) which are used for limiting the movement range of the supporting rod. According to the wall surface orifice plate wave absorber provided by the invention, the pressure and the energy of an explosion wave can be greatly reduced and a good protection effect is generated on personnel, mechanical equipment and engineering structures inside the passage; and moreover, the wave absorber has the characteristics of simple structure and convenience in installation.

Description

technical field [0001] The invention belongs to the field of explosion safety protection, and mainly relates to a wall surface orifice wave suppressor. Background technique [0002] In industries with blasting and excavation processes such as underground construction and mining, blasting operations are inevitable. At the same time, explosion accidents may also occur in underground warehouses used to store explosives and explosives. Both pose serious threats and easily cause greater losses. Compared with the explosion in the outer space, the shock wave produced by the internal explosion is stronger and more destructive. Therefore, it is an important task in the field of safety protection to develop a feasible internal explosion wave suppression protection technology to achieve efficient reduction of strong shock waves. It is an urgent task, if the protective measures of the explosion shock wave can be used properly, the loss will be greatly reduced. [0003] The existing ex...
