DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the present embodiment, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0033] Since aviation kerosene is flammable and explosive, aviation kerosene testing equipment usually includes a combustible gas detector. In related technologies, combustible gas detectors are generally gas sensors based on the principles of catalytic combustion or infrared, with a range of 0-100% LEL, and have good detection sensitivity for aviation kerosene. According to the inspection requirements for combustible gas detectors in the "General Inspection and Maintenance Requirements for Fuel Supply Facilities and Equipment", the combustible gas detector will generate an alarm signal when it detects that the concentration of aviation kerosene reaches the set concentration alarm value. If the alarm fails or the difference between the alarm action value and the alarm setting value exceeds ±3% LEL, the combustible gas detector should be repaired in a timely manner.

[0034] At present, the inspection method of combustible gas detectors mainly relies on manual inspection, specifically, the operator holds a sample bottle filled with aviation kerosene, places the bottle mouth under the probe of each combustible gas detector, shakes the sample bottle to allow the aviation kerosene to evaporate into the combustible gas detector and observes the status of the combustible gas detector to inspect the combustible gas detector. At the same time, given that there are a large number of combustible gas detectors that need to be inspected at the hazardous chemical site and the different locations of each combustible gas detector, it is not only necessary for the operator to hold a sample bottle filled with aviation kerosene to inspect each combustible gas detector one by one, but also for the operator to flexibly adjust the bottle mouth height when holding the sample bottle according to the position of the probe of each combustible gas detector, so as to place the bottle mouth in a suitable position under the probe of each combustible gas detector, so as to facilitate the evaporation of aviation kerosene into the combustible gas detector.

[0035] However, this detection method is very physically demanding for operators. If the operator accidentally breaks the sample bottle, it may also cause jet fuel leakage, which not only pollutes the environment, but also causes the combustible gas detector to continue to alarm and affect the detection. At the same time, this detection method has low detection efficiency for combustible gas detectors, is time-consuming and labor-intensive, and has high labor costs.

[0036] See also Figure 1 to Figure 2 The utility model provides a detection tool 10, comprising a detection auxiliary device 100 and a detection device 200 for an object to be detected. The detection device 200 for an object to be detected comprises a combustible gas detector 210, a support frame 220 for supporting the combustible gas detector 210, and a sample bottle 230 for loading the object to be detected. The detection auxiliary device 100 is used to support the sample bottle 230 containing the object to be detected, and to adjust the position between the bottle mouth of the sample bottle 230 and the probe 212 of the combustible gas detector 210.

[0037] Taking aviation kerosene as an example, the object to be tested can volatilize and produce flammable gas. When the detection tool 10 is in use, the operator first fixes the flammable gas detector 210 and the support frame 220, and then places the sample bottle 230 containing aviation kerosene on the detection auxiliary device 100. The operator uses the detection auxiliary device 100 to support the sample bottle 230 and drive the sample bottle 230 to move, so that the bottle mouth of the sample bottle 230 is aligned with the probe 212 of the flammable gas detector 210 and moves toward the probe 212, so that the aviation kerosene in the sample bottle 230 can volatilize and produce flammable gas to enter the flammable gas detector 210. Next, the operator observes whether the flammable gas detector 210 generates an alarm signal when it detects that the concentration of aviation kerosene reaches the set concentration alarm value, and whether the difference between the alarm action value and the alarm setting value exceeds ±3% LEL, thereby judging whether the flammable gas detector 210 is abnormal, and repairing it in time.

[0038] In the detection tool 10 provided by the utility model, the operator only needs to place the sample bottle 230 containing aviation fuel on the detection auxiliary device 100, and then operate the detection auxiliary device 100 to adjust the distance between the bottle mouth of the sample bottle 230 and the probe 212. The operator does not need to hold the sample bottle 230 and align the bottle mouth with the probe 212 of the combustible gas detector 210, which saves time and effort and has high detection efficiency. At the same time, the detection tool uses the detection auxiliary device 100 to detect the object detection device 200, which can timely discover the abnormality of the object detection device 200 and avoid leakage of the object, thereby improving the operation stability and operation safety of the object detection device 200.

[0039] It should be noted that see Figure 2 The combustible gas detector 210 includes a mounting shell 211 and a probe 212 fixed to the mounting shell 211, and the probe 212 is used to detect the combustible gas generated by the volatilization of the jet fuel. The support frame 220 of the object detection device 200 includes a hanger 221 connected to the mounting shell 211 and a bracket 222 for supporting the hanger 221. The hanger 221 is connected to the mounting shell 211 to fix the combustible gas detector 210.

[0040] See also Figures 1 to 3 This embodiment also provides a detection auxiliary device 100, including a connecting assembly 110, a carrier 120, a transmission mechanism 150 and a driving member 140. The connecting assembly 110 includes at least one connecting frame 110a for connecting the object detection device 200. The carrier 120 is used to carry the sample bottle 230 and is slidably connected to the connecting frame 110a. The transmission mechanism 150 includes a power input end arranged on the carrier 120, and a power output end connected between the power input end and the carrier 120. The driving member 140 is arranged on the carrier 120, and the output end of the driving member 140 is connected to the power input end to drive the power output end to drive the carrier 120 to move along the connecting frame 110a.

[0041] When the detection auxiliary device 100 is in use, the operator uses the connecting frame 110a to connect the detection auxiliary device 100 to the bracket 221 of the object detection device 200. After that, the operator places the sample bottle 230 containing aviation kerosene on the carrier 120, and operates the driving member 140 to transmit the power of the driving member 140 to the power input end of the transmission mechanism 150 through the output end of the driving member 140, and then transmits the power from the power input end to the power output end of the transmission mechanism 150, so as to drive the carrier 120 to move along the height direction 110b of the connecting frame to the probe 212 of the combustible gas detector 210, so as to facilitate the volatilization of aviation kerosene into the combustible gas detector 210. The detection auxiliary device 100 can save the operator's physical strength, and the operator does not need to hold the sample bottle 230 to detect the combustible gas detector 210, while improving the detection efficiency and operation safety of the combustible gas detector 210.

[0042] It should be noted that the connection frame 110a and the combustible alarm 1 can be connected by bolting, welding, clamping, etc. The support frame 120 can be a plate-like structure. Figure 3 The carrier frame 120 in the embodiment can be a U-shaped plate. Meanwhile, the driving member 140 can be a motor, and the output shaft of the motor is connected to the power input end. The driving member 140 can also be a rotating handle, and the operator holds the rotating handle to drive the power input end to provide power.

[0043] See also Figure 3 In some embodiments, in order to facilitate fixing of the sample bottle 230 and prevent the sample bottle 230 from falling off the carrier 120, the bearing portion 121 is provided with a bottle holder 130 for limiting the position of the sample bottle 230. There are many ways to form the bottle holder 130. As an example, the bearing portion 121 includes a first end face 121a for supporting the bottle holder 130 and a second end face 121b facing away from the first end face 121a. The first end face 121a is provided with a recess extending toward the second end face 121b, and the recess forms the bottle holder 130. Optionally, the first end face 121a is provided with a plurality of protrusions extending away from the second end face 121b, and the plurality of protrusions are arranged to form a cavity for supporting the sample bottle 230 to form the bottle holder 130. Optionally, the first end face 121a is provided with a cylindrical structure protruding away from the second end face 121b, and the cylindrical structure forms the bottle holder 130.

[0044] In some embodiments, in order to accelerate the volatilization of the aviation fuel in the sample bottle 230 and accelerate the combustible gas detector 210 to reach the alarm value, so as to further improve the detection efficiency of the combustible gas detector 210, the bottle holder 130 is provided with a cavity for accommodating the sample bottle 230, and a heating layer is provided on the inner wall of the cavity. The aviation fuel in the sample bottle 230 is slightly heated by the heating layer to accelerate the volatilization of the aviation fuel in the sample bottle 230. Optionally, an electric heating wire can be provided on the inner wall of the cavity of the bottle holder 130 to form a heating layer.

[0045] In some embodiments, in order to protect the sample bottle 230, a buffer layer is further provided on the inner wall of the cavity. Optionally, a plurality of elastic materials, such as rubber, sponge, etc., may be provided on the inner wall of the cavity of the bottle holder 130 to form a buffer layer. In addition, the buffer layer provided on the inner wall of the cavity of the bottle holder 130 can form a flexible connection between the sample bottle 230 and the inner wall of the bottle holder 130. The operator can also shake the sample bottle 230 in a small range in the bottle holder 130 to accelerate the flow of the jet fuel in the sample bottle 230, thereby accelerating the volatilization of the jet fuel, and further improving the detection efficiency of the combustible gas detector 210.

[0046] In some embodiments, the sample bottle 230 may also be configured as a wide-mouth bottle to enhance the volatilization effect of the aviation fuel in the sample bottle 230 .

[0047] See also Figure 3 and Figure 4 In some embodiments, to facilitate the operation of the operator, the power input end includes a first transmission member 151 rotatably connected to the carrier frame 120 and connected to the output end of the driving member 140, and the power output end includes a second transmission member 152 rotatably connected to the carrier frame 120 and threadedly matched with the connecting frame 110a, and the first transmission member 151 is engaged with the second transmission member 152.

[0048] It should be noted that when the driving member 140 is set as a rotating handle, in order to facilitate the operator to turn the rotating handle to provide power to the carrier 120 and to achieve self-locking movement, as an example, the transmission mechanism 150 can be set as a worm gear, that is, the first transmission member 151 includes a worm, and the second transmission member 152 includes a worm wheel meshing with the worm.

[0049] Specifically, the worm is connected to the driving member 140 and is rotatably arranged on the carrier 120, the worm wheel is meshed with the worm and is rotatably arranged on the carrier 120, and the worm wheel is sleeved on the connecting frame 110a and is threadedly connected to the connecting frame 110a. When the operator operates the rotary handle to rotate, the rotary handle drives the worm to rotate synchronously, and the worm drives the worm wheel to rotate, and through the threaded cooperation between the worm wheel and the connecting frame 110a, the rotary motion is converted into a linear motion, so that the worm wheel drives the carrier 120 to move along the connecting frame 110a, and the moving distance of the carrier 120 relative to the combustible gas detector 210 can be adjusted, and the distance between the sample bottle 230 on the carrier 120 and the probe 2121a is adjusted, so that the sample bottle 230 is placed in a suitable position below the probe 212 of the combustible gas detector 210, so as to facilitate the volatilization of aviation fuel into the combustible gas detector 210. Of course, in other embodiments, the transmission mechanism 150 can also be set as a spur gear set, a helical gear set, a ball screw, etc., which will not be described in detail in the utility model.

[0050] See also Figure 5 and Figure 6 In some embodiments, in order to improve the structural stability of the detection auxiliary device 100, the support frame 120 includes a support portion 121 for supporting the sample bottle 230, and a mounting portion 122 fixed on both sides of the support portion 121 and rotatably connected to the first transmission member 151.

[0051] The bearing portion 121 is provided with a first mounting hole extending along the height direction of the connecting frame 110a, and the second transmission member 152 is rotatably connected to the first mounting hole. The second transmission member 152 is provided with a second mounting hole extending along the height direction of the connecting frame 110a, and the inner wall of the second mounting hole is provided with an internal thread. The connecting frame 110a is placed in the second mounting hole and the outer wall of the connecting frame 110a is provided with an external thread matching the internal thread, so that the bearing frame 120 can reciprocate along the height direction of the connecting frame 110a through spiral transmission.

[0052] It should be noted that a tapered roller bearing 160 may be installed between the second transmission member 152 and the first mounting hole to achieve a rotational connection between the second transmission member 152 and the supporting frame 120 .

[0053] See also Figures 5 and 6 In some embodiments, in order to facilitate the installation of the detection auxiliary device 100 to the object detection device 200, the connecting frame 110a includes a first connecting portion 111 for connecting the hanger 221, and a second connecting portion 112 fixed to the first connecting portion 111 and extending along the height direction of the connecting frame 110a. Optionally, the first connecting portion 111 is configured as an arc hook, which can be configured as a ring, and the arc hook is provided with a notch to facilitate its sleeve on the hanger 221. Optionally, the second connecting portion 112 is configured as a screw.

[0054] It should be noted that the operator can directly hang the connecting frame 110a on the hanger 221 of the object detection device 200 using a hook to achieve rapid installation of the detection auxiliary device 100 and the object detection device 200. The second connecting portion 112 is configured as a screw to facilitate threaded engagement between the worm gear and the connecting frame 110a.

[0055] Of course, in other embodiments, in order to improve the connection stability between the detection auxiliary device 100 and the object detection device 200, a slot can be set on the bracket 222 of the support frame 220, and an insert block that matches the slot can be set on the supporting frame 120 to improve the connection stability between the detection auxiliary device 100 and the object detection device 200.

[0056] Continue to see Figure 5In some embodiments, in order to improve the connection stability between the detection auxiliary device 100 and the object detection device 200, the connection assembly 110 includes two connection frames 110a, the two connection frames 110a are arranged at intervals on the bearing portion 121, the bottle holder 130 is arranged between the two connection frames 110a, and the bottle holder 130 and the two connection frames 110a are in the same straight line.

[0057] It should be noted that when the connecting assembly 110 includes two connecting frames 110a, the power input end may include a worm, and the power output end may include two worm wheels, so as to realize a one-to-two driving mode in which one worm drives two worm wheels. Specifically, the bearing parts 121 of the two bearing frames 120 are provided with two first mounting holes, and rotatable worm wheels are respectively provided in the two first mounting holes. The first connecting frame 110a is inserted into the second mounting hole of one of the worm wheels and is threadedly connected with the worm wheel, and the second connecting frame 110a is inserted into the second mounting hole of the other worm wheel and is threadedly connected with the worm wheel. At the same time, the two ends of the worm are respectively rotatably connected to the mounting parts 122 on both sides of the bearing part 121, and the worm is meshed with the two worm wheels at the same time. One end of the rotating handle passes through the mounting part 122 and is connected to one end of the worm. The operator drives the worm to rotate by rotating the handle, and the worm drives the two worm wheels to rotate simultaneously, and the spiral transmission between the worm wheel and the connecting frame 110a drives the bearing frame 120 to move along the connecting frame 110a.

[0058] At the same time, when the bottle holder 130 and the two connecting frames 110a are in the same straight line, when the two connecting frames 110a are hung to the specified position of the hanger 221 through the arc hook, the bottle mouth of the sample bottle 230 in the bottle holder 130 can be directly below the probe 212, and the supporting frame 120 is raised in the height direction of the connecting frame 110a, which can reduce the distance between the sample bottle 230 and the probe 212, making it easier for the combustible gas detector 210 to detect the volatilized jet fuel to reach the alarm value.

[0059] In addition, reference Figure 5 When the connection assembly 110 is provided with two connection frames 110a, the axes 111a of the arc-shaped hooks of the two connection frames 110a can be respectively provided with an angle with the length direction 220a of the support frame, that is, the two arc-shaped hooks can be slightly inclined (for example Figure 5As shown, it is tilted from right to left.) With this arrangement, when the arc-shaped hook of the connecting frame 110a is hung on the hanger 221, the connecting frame 110a can be prevented from shifting in the length direction 220a of the support frame, thereby improving the connection stability between the detection auxiliary device 100 and the object detection device 200, so that the bottle mouth of the sample bottle 230 can be located below the probe 212, which is convenient for the combustible gas detector 210 to detect the volatilized jet fuel to reach the alarm value, thereby improving the detection efficiency. Of course, in other embodiments, the axes of the arc-shaped hooks of the two connecting frames 110a can also be perpendicular to the length direction 220a of the support frame, which is not elaborated in the utility model.

[0060] See also Figure 7 In some embodiments, in order to facilitate the operator to adjust the position of the bottle holder 130, the detection auxiliary device 100 also includes a moving component 170, the moving component 170 includes a fixed portion 171 fixed to the bearing portion 121 and located between the two connecting frames 110a, and a moving portion 172 slidably connected to the fixed portion 171, and the bottle holder 130 is fixed to the moving portion 172.

[0061] It should be noted that the bottle holder 130 can be moved between the two connecting frames 110a by the moving assembly 170, so that the position between the sample bottle 230 and the probe 212 in the bottle holder 130 is convenient for the combustible gas detector 210 to detect the volatilized jet fuel to reach the alarm value. Optionally, the moving assembly 170 can be set as a linear motor, the fixed part 171 is equivalent to the stator part of the linear motor, and the moving part 172 is equivalent to the mover part of the linear motor. After the linear motor is started, the bottle holder 130 can move along the fixed part 171. Optionally, the moving assembly 170 can also be set as a gear rack assembly, the fixed part 171 is equivalent to the rack end, and the moving part 172 is equivalent to the gear end moving along the rack end. The drive motor is installed on the gear end to drive the gear end to drive the bottle holder 130 to move. In addition, in order to remind the operator that the distance between the sample bottle 230 and the probe 212 of the combustible gas detector 210 has reached the set position, position sensors can be installed at the bottle holder 130 and the probe 212 respectively.

[0062] In other embodiments, moving components 170 in other directions may be provided on the bearing portion 121 to enable the bottle holder 130 to move in other directions to meet its use requirements, and the present invention does not limit this.

[0063] See also Figure 7In some embodiments, in order to further improve the connection stability between the connecting frame 110a and the hanger 221, a third connecting portion 113 may be installed at one end of the second connecting portion 112 away from the first connecting portion 111, so as to increase the contact area between the connecting frame 110a and the ground or other external platform through the connecting frame 110a, thereby improving the connection stability. Optionally, the third connecting portion 113 may be configured as a boss structure.
