Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
SF6 gas leak detection gas collection detector of the present invention, including detector host 13, the top of detector host 13
Installation data line 12, one end installation probe 11 of data line 12, pop one's head in 11 periphery installation cone cover 1, cover 1 it is outer
It is coated with wear-resistant composite bed 20, wear-resistant composite bed 20 week to be made of high strength multi-layer composite material, including nonwoven layer 23, nonwoven
Layer of polyurethane 22 is arranged in the top of layer of cloth 23, and cotton fiber layer 25 is arranged in the lower part of nonwoven layer 23, and the inside of cotton fiber layer 25 is set
Elastic fibrous layer 26 is set, several reinforced fiber ropes 27 are installed on elastic fibrous layer 26, one end of reinforced fiber rope 27 and elasticity are fine
It ties up layer 26 to connect, elastic webs 28 is set inside layer of polyurethane 22, several cordage 29, fiber are installed in 23 top of nonwoven layer
Rope 29 is arc rope, and the direction of 29 arc of cordage is upward, and the both ends of cordage 29 are all connected with nonwoven layer 23, cordage 29 it is upper
Portion connects elastic webs 28, opens up several first cylindrical grooves 30 vertically in nonwoven layer 23, level opens up in nonwoven layer 23
Several second cylindrical grooves 31, the second cylindrical groove 31 are located at the side week of the first cylindrical groove 20, the inside and first of the second cylindrical groove 31
The inside of cylindrical groove 30 communicates；The smaller diameter end of cover 1 is connect with probe 11, and elastic seal ring is arranged in the larger diameter end of cover 1,
Elastic seal ring is the circular cone shape sealing ring being made of the trapezoidal sheet rubber 2 of muti-piece, and the narrow end and cover 1 of every piece of sheet rubber 2 connect
It connects, partly overlaps between wantonly two pieces adjacent sheet rubbers 2.
In use, operator covers in cover 1 at equipment surface to be measured, cover 1 is compressed on the other hand, makes cover 1 and is detected
Equipment fits closely composition enclosure space, and the other hand manipulation detector host 13 is detected.Since elastic seal ring is by more
The trapezoidal sheet rubber 2 of block constitutes circular cone shape sealing ring, and the narrow end of every piece of sheet rubber 2 is connect with cover 1, and as shown in figure 3, wantonly two
It partly overlaps between the adjacent sheet rubber 2 of block, therefore, the elastic seal ring can the production of the pressure size according to suffered by cover 1
Raw corresponding deformation, thus, it can be ensured that it may make up enclosure space when the face contact to be measured of cover 1 and any shape
As shown in Fig. 2, the elastic webs 28 of the present embodiment wear-resistant composite bed 20 can increase with the cooperation of cordage 29
Nonwoven layer 23 and the tensile strength that layer of polyurethane 22 is improved while 22 bonding strength of layer of polyurethane, avoid composite material by
In the adhesion strength of non-woven fabrics and polyurethane not strong the phenomenon that being detached from when in use.Cordage 29 is arc rope, cordage 29
The direction of arc is upward, and when being coated with layer of polyurethane 22, cordage 29 can tangle layer of polyurethane 22, avoids nonwoven layer 23 and poly- ammonia
Ester layer 22 is detached from.Elastic webs 28 can improve layer of polyurethane 22 while improving the tensile strength of layer of polyurethane 22
Elasticity.First cylindrical groove 30 can penetrate into polyurethane when being coated with layer of polyurethane 22, hang down to be formed in the first cylindrical groove 30
Histogram to polyurethane block, further increase the bonding strength of layer of polyurethane 22 Yu nonwoven layer 23.Second cylindrical groove 31 can be with
Polyurethane is penetrated into when being coated with layer of polyurethane 22, the polyurethane block of horizontal direction is formed in the second cylindrical groove 31, thus into one
Step improves the bonding strength of layer of polyurethane 22 and nonwoven layer 23.The adherent fashion more adduction of layer of polyurethane 22 and nonwoven layer 23
Reason, to substantially increase the bonding strength of layer of polyurethane 22 Yu nonwoven layer 23.Nonwoven layer 23 can greatly increase poly- ammonia
The tensile strength of ester layer 22 provides substrate for layer of polyurethane 22.Since nonwoven layer 23 is prone to wear, cotton fiber layer 25 can be with
Prevent 23 Rapid Damage of nonwoven layer.Reinforced fiber rope 27 can increase the tensile strength of cotton fiber layer 25, to mention significantly
The high intensity of cotton fiber layer 25.
As shown in Fig. 2, enhancing gauze layer 24 is arranged in the present embodiment between nonwoven layer 23 and cotton fiber layer 25.Enhance yarn
Stratum reticulare 24 can cooperate when cotton fiber layer 25 and nonwoven layer 23 are bonded with adhesive, increase cotton fiber layer 25 and nonwoven layer
23 bonding strength.Further, protective layer 21 is set on the top of layer of polyurethane 22.Setting protective layer 21 can prevent poly- ammonia
Ester layer 22 is easily damaged.
To further facilitate testing staff's operation, as shown in Figure 3 and Figure 4, the periphery of cover 1 can be equipped with fixed disc 3, Gu
Fixed disk 3 is fixedly connected with cover 1, and three hold-down mechanisms are installed on fixed disc 3, and three hold-down mechanisms circumferentially uniformly divide
Cloth；Hold-down mechanism is connected and composed by casing 5, spring 7, universal joint 15 and electromagnet 8, and casing 5 is flexibly connected with fixed disc 3,
Specifically, opening up corresponding through-hole 4 on fixed disc 3, casing 5 is located in through-hole 4, can the linear movement of opposing through-bores 4；Casing
For 5 rear portion periphery setting limit convex along 6, spring 7 is installed in the periphery of casing 5, spring 7 be located at limit convex along 6 and fixed disc 3 it
Between；Universal joint 15 is installed in the front end of casing 5, and electromagnet 8 is installed on universal joint 15, and electromagnet 8 is connected by universal joint 15 and casing 5
Connect, each electromagnet 8 can be made freely to adjust its angle position according to the shape of tested equipment different surfaces, as far as possible with equipment list
Face paste is closed closely, so as to the pressure provided fixed disc 3；Power supply 9 is installed on cover 1, switch 10, power supply 9 are installed on power supply 9
It is connect respectively with three electromagnet 8 by three conducting wires.Electromagnet 8 is by casing 5, limit convex along 6 and spring 7 indirectly to fixation
Disk 3 applies pressure, rather than directly applies pressure to fixed disc 3 by casing 5.Since spring 7 and limit convex can along 6 cooperations
It works as a buffer, and the distance that can realize that the relatively fixed disk 3 of electromagnet 8 stretches out is different, therefore, both can make electromagnet 8 and set
Standby surface is closely attracted, it is ensured that the effect that electromagnet 8 exerts a force to fixed disc 3, and electromagnet 8 can be prevented prominent to fixed disc 3
So force, causes the damage of fixed disc 3.
In use, cover 1 is placed in tested equipment detection position, 10 are turned on the switch, three electromagnet 8 is made to be powered,
While three electromagnet 8 and tested equipment are fixed, by universal joint 15, casing 5, limit convex along 6 and 7 pairs of fixations of spring
The pressure of disk 3 is directed toward the power of tested equipment, moves linearly since casing 5 can fix disk 3 relatively, it can be ensured that three electricity
Magnet 8 is capable of fixing in the equipment of surface irregularity.At this point, testing staff, which need to only manipulate detector host 13, carries out detection behaviour
Make, to be further simplified detection process.
As shown in Figure 1, sucker 14 is installed at the rear portion of detector host 13.Detector host 13 can be inhaled by sucker 14 one
Side, convenient for taking the readings, when detection, is not required to hand-held, operates eased.
The technology contents of the not detailed description of the present invention are well-known technique.
