Abstract
The utility model discloses an energy accumulating seismic source shell used in geological exploration, which comprises a shell housing, a top cap connected with the upper part of the shell housing, a tail wing connected with the tail part, and a main charge in the shell housing. The utility model is characterized in that the energy accumulating shell adopts an axially symmetric energy accumulating structure, namely, the shell housing is in the shape of a parabola, and the upper end of the shell housing is provided with a conical energy accumulating hood. As a result, the energy accumulating seismic source shell has the characteristics of small charge quantity, high energy utilization rate of explosives, strong orienting property, favorable water resisting property, small earthquake vibration to the periphery, reasonable structure, convenient use, etc.
Description
This is novel to relate to a kind of hypocentrum cartridge that geologic prospecting is used that is used for, and particularly has the direction propagation performance, to the destructive little cumulative hypocentrum cartridge of surrounding environment.
At present, along with the deep development of geologic prospecting work, the exploratory area has been deep into the area of geographical environment complexity such as the rural area is intensive, edge, cities and towns.And the hypocentrum cartridge that uses in the geologic prospecting mostly is cylindrical grain greatly, after the blast, the detonation substance that produces along the direction of the former grain surface of near normal to around disperse, effective active area only equals the area of grainend, therefore capacity usage ratio is low, bigger to the surrounding environment vibration limits, especially in the distance cities and towns or the nearer region of buildings can't use.
This novel goal of the invention is for overcoming the above-mentioned disadvantage bigger to the surrounding environment vibration limits, provide a kind of explosive load little, explosive energy utilization factor height, the cumulative hypocentrum cartridge with direction propagation performance.
This is novel for realizing goal of the invention, and the technical scheme of taking is as follows:
This cumulative hypocentrum cartridge, it comprise top cap that body, its body top connect, empennage that its afterbody connects and in the main charge that is equipped with, it is characterized in that: described body is taked rotational symmetry cumulative structure, the internal layer that is body is parabola shaped housing, be provided with in the columniform extension element on the top of body and overlap, and top end is provided with conical energy gathering cap within it, make it form " spill hole " at conical outside surface, its role is to concentrate the energy of detonation product and produce cavity effect.
This novel feature also is: the thickness of body bottom is greater than the thickness on top.
This novel compared with prior art beneficial effect is as follows:
This novel and existing hypocentrum cartridge is compared, and it is little to have explosive load, explosive energy utilization factor height, characteristics such as the strong water resisting property of directional properties is good, and is little to ambient vibration, rational in infrastructure, easy to use.This hypocentrum cartridge adopts the cumulative structure, and promptly body is parabola shaped housing, and has energy gathering cap.Make its explosive energy utilization factor height, after the ammunition blast, when detonation substance is dispersed, concentrate to axis earlier, pool all very high air-flow of one speed and pressure, and produce cavity effect.After this hypocentrum cartridge blast, the detonation wave propagation has relative directionality, produces seismic event thus and promptly has relative directionality, has strengthened the energy of the incident wave of specific direction propagation, thereby has improved the energy of effective reflection wave.Checking after tested, the energy ratio of this bullet vertical direction can reach 10～16: 1, and (downwards: upwards) the energy ratio with level can reach 2～3: 1 vertically downward, therefore this bullet lacks than the powder column explosive load of plain cylindrical form, produce the effect that is equal to common powder column, and it is little to the surrounding environment destructiveness, can be used for safely apart from the seismic prospecting in nearer work area, cities and towns, also can be used for the geologic prospecting in circumstance complication areas such as the complicated shrimp of open-air water conservancy projects pond, chicken house, quick-fried scooter 5000～7500M/S, power is more than 330ML.
The description of drawings that this is novel:
Fig. 1 is the structural representation of cumulative hypocentrum cartridge.
Below in conjunction with accompanying drawing this novel technical scheme detail is illustrated:
Referring to Fig. 1, this is novel, it comprise body 5, the top cap 1 that links to each other with its top, empennage 6 that its afterbody is connected and in the main charge 3 that is equipped with, it is characterized in that: described body 5 is taked rotational symmetry cumulative structure, be that body 5 is parabola shaped plastic casing, the thickness of the bottom of body 5 is greater than one times of top, and after purpose was the constraint explosive initiation, the horizontal transmission of its fried Hong ripple was concentrated it and passed ripple downwards; Body 5 upper ends are connected to columniform middle cover 4, and have conical energy gathering cap 2.After adding cover 4, can adjust the explosive load of body, middle cover 4 and body 5 are by being threaded.When the user needs 1 kilogram of dose, need put this part, when 0.5 kilogram of dose, then without overlapping 4 in this, at this moment energy gathering cap 2 is directly installed on the top end in the housing 5; Above-mentioned connection empennage 6 is used to prevent that detonator from falling down and is broken, and is provided with internal thread within it, under the situation of needs, can link with another body 5, in order to increase whole energy.
Claims (2)
1, a kind of cumulative hypocentrum cartridge, it comprises body (5), the top cap (1) that its body (5) top connects, the empennage (6) that its afterbody connects and in the main charge (3) that is equipped with, it is characterized in that: described body (5) is taked rotational symmetry cumulative structure, the internal layer that is body (5) is parabola shaped housing, be provided with cover (3) in the columniform lengthening on its top, and top end is provided with conical energy gathering cap (2) within it, in outer form " the spill hole " of energy gathering cap, make the biography ripple direction of its detonation wave concentrate on parabolical axis, and produce cavity effect.
2, a kind of cumulative hypocentrum cartridge according to claim 1 is characterized in that: the thickness of body (5) bottom is greater than the thickness on top.
