Description

The geologic structure sounding rocket

The utility model relates to a kind of instrument of burying vibration source or vibration measuring instrument in geologic prospecting underground, particularly a kind of geologic structure sounding rocket.

When underground mines such as searching oil, coal, in order to verify stratal configuration, must utilize vibration source that the ripple that shakes is sent on the stratum, by to returning the detection of the ripple that shakes, can understand the geologic structure of the following certain depth in the face of land.The shake mode of ripple of generation generally is that explosive column is imbedded underground detonating, in order to obtain more reliable data, often wave detector is also imbedded underground, and with explosive column at a distance of certain distance, to receive the explosive column vibrating wave signal that the back produces the stratum that detonates.The method of burying explosive column or wave detector at present underground generally is to hole with rig earlier, then explosive column or wave detector are put into the hole, though use rig boring controlling depth easily, but speed of application is slower, when at sea constructing, and executive cost height not only, human input is big, and use mini-plant sometimes, and also can be subjected to the restriction of weather, sea situation and the depth of water, be difficult to construct.

The purpose of this utility model provide a kind of can be easily and fast and economic and reliable with explosive column or the buried geologic structure sounding rocket of wave detector.

The purpose of this utility model is achieved through the following technical solutions.The geologic structure sounding rocket mainly includes the two large divisions: a part is a head, and another part is a rocket engine.It is characterized in that head is made up of nose cone, warehouse, explosive column or wave detector, nose cone links to each other with warehouse, and explosive column or wave detector are positioned at warehouse, and the lead-in wire of explosive column or the output signal line of wave detector are by drawing in the hole on the warehouse.Rocket engine is by the middle end, igniter cartridge, the cartridge bag frame, the firing chamber, solid propellant grain, jet pipe, grate, sealing-plug, bonnet and harness are formed, the cavity at the end in the middle of igniter cartridge and cartridge bag frame are positioned at successively, one end of firing chamber is connected with the centre at the end, the front end face of firing chamber is just in time located the cartridge bag frame, in the firing chamber, place solid propellant grain, grate is positioned at the afterbody of firing chamber, there is tubaeform through hole at two ends in the jet pipe, front end also has internal thread and is used for being connected with the firing chamber, in the tubaeform through hole in jet pipe rear end (expanded bore) mouth sealing-plug is installed, the centre of sealing-plug has binding post, gland is positioned at the afterbody of jet pipe, electric igniter in harness one end and the igniter cartridge connects, the other end is drawn from the through hole of cartridge bag frame, through the firing chamber, behind the through hole of grate, be connected on the binding post of jet pipe tail end sealing plug, from gland, draw at last.Head is connected with the middle end by warehouse with rocket engine.When the utility model uses, on the job platform geologic structure sounding rocket is being contained on the simple and easy launcher earlier, with manpower or small-sized lifting appliance launcher is sunk under water then, cut-in point ignition source on job platform, utilize the powerful thrust of rocket engine that the geology detecting rocket is pushed the stratum certain depth, and then lead by from the warehouse hole, drawing, explosive column is ignited, detonation wave during ignition will be propagated to the depths, stratum, when running into different stratal configurations, having the different wave direction ground that shakes again returns, at this moment, utilize the wave detector be embedded in another point to detect again to receive and return waveform signal, will detect the data handling machine of data transmission to the surface work platform with signal wire, handle by computer data at last, just can obtain stratal configuration shape data.

The utility model compared with prior art its significant advantage is: (1) uses manpower and material resources sparingly, easy construction is rapid, bury explosive column or wave detector underground with the rig boring method and not only need equipment such as cover boring, lifting and anchoring, also need the above work compound of 10 people, and the drilling operation time is more than 30 minutes, only need a small-sized launcher and a simple lifting appliance and utilize the utility model to bury explosive column or wave detector underground, operating personnel only need 3 people, and an engineering time only needs 5 minutes; When (2) constructing on the water, be subjected to the restriction of weather, sea situation and the depth of water little, as long as weather and sea situation that workboat is merely able to locate, the utility model can both use, when the depth of water is used less than the mud of 150m or sand bed geology, explosive column or wave detector can be imbedded underground 4～6m.

Concrete structure of the present utility model is provided by the following drawings and embodiment

Geologic structure sounding rocket with the long 1000mm of diameter 65mm is an example below, and the utility model is described in further detail.

Referring to accompanying drawing, the geologic structure sounding rocket is made up of nose cone 1, warehouse 2, explosive column or wave detector 3, the middle end 4, igniter cartridge 5, lead-in wire or output signal line 6, cartridge bag frame 7, firing chamber 8, solid propellant grain 9, jet pipe 10, grate 11, sealing-plug 12, gland 13 and harness 14, nose cone 1 and warehouse 2 can adopt the LY12 duralumin, hard alumin ium alloy, adopt between them and be threaded, as placing explosive column 3 in the warehouse 2, then explosive column 3 adopts hexogen or the TNT explosive of 1kg, as placing wave detector 3 in the warehouse, then wave detector is selected the standard wave detector.Draw their lead-in wire or the hole of output signal line 6 from warehouse 2.The tail end of warehouse 2 has internal thread and is connected with the middle end 4, solid propellant grain 9 in the firing chamber 8 is made by the double base propellant of 1.3kg, the middle end 4, firing chamber 8, jet pipe No. 45 carbon steels of 10 employings or 30CrMnSi alloy steel are made, two ends have the loudspeaker through hole in the jet pipe 10, its front end hydraucone is identical with 8 apertures, firing chamber, also have one section tapped through hole before the front end loudspeaker through hole in jet pipe 10, be used for being connected with the tail end of firing chamber 8, sealing-plug 12 is made by rubber, loudspeaker aperture, the rear end coupling of its shape and jet pipe 10, have binding post on the sealing-plug 12, gland 13 is a common plastics, and it is the tail end of withholding at jet pipe 10.
