Description
The utility model relates to a kind of universal head that is used for seismoreceiver, is particularly suitable for the universal head of two components or three-component seismometer.
When using two components or 3-component earthquake detector, require seismoreceiver vertically to insert ground, and require the directional bea con on the seismoreceiver shell to aim at line direction.Burying when plugging in seismoreceiver,, therefore, can only roughly azimuth mark be aimed at line direction at present because wave detector can not be done suitably to rotate with respect to base, and by pulling the method adjustment level of seismoreceiver shell.This method often makes bearing accuracy not reach technical requirement, and owing to pull tail cone, can make the coupling on wave detector and ground unreliable.
The purpose of this utility model provides a kind of technical scheme that can overcome above-mentioned deficiency.Seismoreceiver universal head of the present utility model can make seismoreceiver after inserting ground, still can adjust the position angle and the vertical inclination angle of seismoreceiver easily, and make seismoreceiver and ground good coupling.
Seismoreceiver universal head of the present utility model, by the wave detector housing that the seismoreceiver core body is housed, multi-directional ball, multi-directional ball fixed cover, lock-screw, base plate, tail cone, the adjustment support that pocket transit is housed is formed.The seismoreceiver housing that detector core body is installed is fixedlyed connected with multi-directional ball; There are a sphere that engages with multi-directional ball or the conical surface in the center of plate upper surface, form spherical hollow space with the multi-directional ball fixed cover, the multi-directional ball fixed cover is connected by three lock-screws that equidistantly distribute with base plate, multi-directional ball is contained in this spherical hollow space, and can in spherical hollow space, make level and vertical rotation, adjust lock-screw, multi-directional ball can be locked, constitute an adjustable seismoreceiver universal head; Three tail cones are housed on the lower surface of base plate, are used for gimballed base is fixed on the ground.When the position angle of adjusting seismoreceiver and horizontality, be contained in the adjustment support that pocket transit is housed on the top cover of seismoreceiver housing by register pin, rotate synchronously with seismoreceiver, according to the position angle of pocket transit indication and the state of horizontal bubble, the wave detector housing that adjustment links to each other with multi-directional ball, the position angle indicated when pocket transit meets the requirements, when the bubble of transit is placed in the middle, the orientation and the horizontality (vertical inclination angle) that promptly show seismoreceiver mix up, and available lock-screw locks multi-directional ball.In the wave detector housing, the detector core body of the natural frequency 2-100Hz that can pack into as required constitutes two components or three-component seismometer.
The utility model has the advantages that: seismoreceiver housing and multi-directional ball are connected together, constitute an adjustable seismoreceiver universal head, even burying, seismoreceiver is inserted on the less-than-ideal ground, also can easily adjust position angle and vertical inclination angle (horizontality) of seismoreceiver, and can guarantee the good coupling on wave detector and ground, for the seismoreceiver work of inserting of burying in the open air provides convenience.The seismoreceiver universal head that the utility model provides guarantees that seismoreceiver once buries to insert the good coupling that can reach with ground, simultaneously, under the motionless prerequisite of wave detector universal head tail cone, positioning error≤2 °, vertical inclination angle≤1.5 °.Because in the wave detector housing, can constitute two components or three-component seismometer according to pack into the detector core body of natural frequency 2-100Hz of need of work, therefore enlarged the scope of application of this wave detector universal head.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model
Among the figure: 1 for installing the wave detector housing of seismoreceiver core body; 2 is multi-directional ball; 3 is the multi-directional ball fixed cover; 4 is lock-screw; 5 is base plate; 6 is tail cone; 7 is pocket transit; 8 for adjusting support; 9 for being positioned at the register pin of adjusting the support bottom; 10 is the pilot hole on the wave detector housing top cover; 11 is seismoreceiver extension line (speech line).
Being equipped with on the wave detector housing 1 of seismoreceiver core body, have Directional Sign, 2 pilot holes are arranged on its top cover.Fixedly connected with multi-directional ball 2 in the bottom of wave detector housing 1.There is a sphere that engages with multi-directional ball or a conical surface at the upper surface center of base plate 5, and base plate 5 constitutes spherical hollow space with multi-directional ball fixed cover 3, and multi-directional ball 2 is contained in this spherical hollow space.Be connected by 3 lock-screws 4 that equidistantly distribute between multi-directional ball fixed cover 3 and the base plate 5, adjust lock-screw 4 and can make multi-directional ball 2 free movable or locked in above-mentioned cavity.3 tail cones 6 are housed on the lower surface of base plate 5, are used for making seismoreceiver reliably to contact, reach good coupling with ground.Above adjustment support 8, be equipped with and be used to adjust seismoreceiver horizontality and azimuthal pocket transit 7, on the base 2 register pins 9 are being arranged below the adjustment support 8, cooperate with 2 pilot holes 10 on seismoreceiver housing 1 top cover, be used for fixing the adjustment support.The length of support 8 should guarantee that the pocket transit of its top is not subjected to the influence in seismoreceiver magnetic field.When the position angle of adjusting wave detector and vertical inclination angle (horizontality), earlier the Directional Sign on the wave detector housing 1 is aimed at survey line, the adjustment support 8 that pocket transit 7 is housed is placed on the top cover of seismoreceiver housing 1, register pin 10 is inserted in the pilot hole 11, at this moment, wave detector housing 1 just can be done horizontal direction and vertical direction rotation with respect to base plate 5 simultaneously with the adjustment support 8 of its top cover top.By observing the position angle and the bubble center condition of pocket transit 7, wave detector housing 1 is adjusted.After finishing adjustment, multi-directional ball 2 is locked with 3 lock-screws 4.After adjustment finishes, will adjust support and take off, and be put into again and carry out orientation and horizontal adjustment on the next seismoreceiver.In the utility model, multi-directional ball 2, multi-directional ball fixed cover 3, lock-screw 4, base plate 5, adjustment support 8 all adopt nonmagnetic substance to make.
