Abstract
The utility model provides a shock prevention and collision prevention protective body for a detector probe. The shock prevention and collision prevention protective body has three stages of protection, and is characterized in that a compression ring, a sliding box and a spring form first-stage shock prevention; in the first-stage shock prevention, the compression ring is arranged between a tube seat and a tube seat joint, the sliding box is arranged below the tube seat, and the spring is arranged below the sliding box; in second-stage shock prevention, a section of buffering cylinder is arranged below the tube seat joint, and a spring and a compression ring are arranged in the buffering cylinder; the tail ends of the spring and the compression ring can be connected with a stay tube which is connected with an external circuit board bracket; and a spring and a compression ring are arranged in a gap between the stay tube and the buffering cylinder so as to form third-stage shock prevention. The utility model has the advantages that by using the shock prevention and collision prevention protective body for the detector probe, the damage condition of the probe can be improved greatly, and a damage rate is reduced from 20 percent to below 10 percent.
Description
(1) technical field
The utility model relates to a kind of protector of detector probe, particularly a kind of shockproof anti-protection body that hits of detector probe.
(2) background technology
Often adopt detector probe during detection; Mainly be made up of scintillator and photomultiplier like scintillation detector, using more scintillator at present is sodium iodide and cesium iodide, and they are density greater than 4 glass crystal; What photomultiplier adopted is the optical glass shell, and they are vitreum.Because it is this two device is vitreum, broken easily when running into vibrations or bump.Detector probe maintenance operation, transportation, in the moving process of down-hole, it is unavoidable that vibrations or impact events take place.According to statistics in the past, employ the gamma appearance 100 times, detector probe is damaged for nearly 20 times, and these damage and to cause by vibrations or bump.The shock-proof and anti-collision protection question of detector probe becomes an important problem.
(3) summary of the invention
The purpose of the utility model is to design a kind of shockproof anti-protection body that hits of detector probe, to solve the problem of detector probe ability shock-proof and anti-collision.
The technical scheme of the utility model: a kind of detector probe shockproof anti-hits protection body and is made up of three grades of protection settings; It is characterized in that: the shockproof setting of the first order is made up of pressure ring, Slide Box and spring; Concrete structure is between the joint of base and base pressure ring to be installed; Be provided with spring below the following installation Slide Box of base, Slide Box; The shockproof setting in the second level is below the base joint, to increase by one section dsah-pot again, is provided with spring and pressure ring in the dsah-pot; But connect the pull bar of outer end circuit board bracket in succession at the end bank of spring and pressure ring; Can refill spring and pressure ring in trombone slide and the dsah-pot internal clearance, constitute the shockproof setting of the third level.
The shockproof anti-protection body that hits of aforesaid detector probe is to connect probe through the base joint that the outside of photomultiplier transit base in detector probe is provided with.
Aforesaid detector probe shockproof anti-hits in the protection body three line generations of generation photomultiplier transit base twisted wire when avoiding installing and removing instrument, on Slide Box, is added with the anti-rotation jackscrew.
The shockproof anti-concrete structure that hits protection body of aforesaid detector probe can be to be made up of one to multiple level shockproof structure.
The superiority of the utility model: 1, the Slide Box of dress photomultiplier transit base, borrow spring that photomultiplier is upwards pushed up, guarantee the coupling on photocathode and scintillator glass window plane, improve detection efficient.2, Slide Box adds the anti-rotation jackscrew, when avoiding installing and removing instrument, three line generations of photomultiplier transit base twisted wire takes place.3, the shockproof anti-use of hitting protection body of detector probe makes the probe damaged condition that bigger improvement arranged, and the spoilage from 20% drops to below 10%.
(4) description of drawings
Accompanying drawing 1 is the structural representation of the utility model,
Wherein: 1, detector probe, 2, the shockproof anti-protection body that hits of detector probe, 3, the photomultiplier transit base, 4,10,13, pressure ring, 5, Slide Box, 6, the anti-rotation jackscrew, 7,9,11, spring, 8, the base joint, 12, dsah-pot,, 14, trombone slide.
(5) specific embodiment
As shown in the drawings: a kind of detector probe 1 shockproof anti-hits protection body 2 and is made up of multistage protection setting; It is characterized in that: the shockproof setting of the first order is made up of pressure ring 4, Slide Box 5 and spring 7; Concrete structure is between the joint 8 of base and base pressure ring 4 to be installed; Be provided with spring 7 below the following installation Slide Box 5 of base, Slide Box 5; The shockproof setting in the second level is below base joint 8, to increase by one section dsah-pot 12 again, is provided with spring 9 and pressure ring 10 in the dsah-pot; But connect the pull bar 14 of outer end circuit board bracket in succession at the end bank of spring 9 and pressure ring 10; Can refill spring 11 and pressure ring 13 in trombone slide 14 and dsah-pot 12 internal clearances, constitute the shockproof setting of the third level.
The shockproof anti-protection body that hits of aforesaid detector probe is to connect probe through the base joint 8 that the outside of photomultiplier transit base in detector probe is provided with.
Aforesaid detector probe shockproof anti-hits in the protection body three line generations of generation photomultiplier transit base twisted wire when avoiding installing and removing instrument, on Slide Box, is added with anti-rotation jackscrew 6.
The shockproof anti-concrete structure that hits protection body of aforesaid detector probe can be to be made up of one to multiple level shockproof structure.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
