Description

Technical Field

[0001] The utility model relates to the field of detector equipment, and more specifically to a detector for detecting natural gas distribution. Background Art

[0002] Natural gas is a clean, environmentally friendly, high-quality energy source that produces less carbon dioxide than other fossil fuels when burned. Therefore, most residents in my country choose to use natural gas for fires. Natural gas is mostly stored in underground rock formations, so it is necessary to use geophones to detect the distribution of underground natural gas. Geophones mainly help workers identify the specific distribution of natural gas by detecting useful information in the fluctuation signal.

[0003] When conducting natural gas exploration, most construction sites will first dig a tunnel on the ground, and then use cranes and other equipment to drop the detector into the tunnel for detection. Existing detectors only use metal shells to wrap the internal components, and the distribution of gravel inside the tunnel is complicated, which can easily cause collision and shaking of the detector during the drop process, eventually causing damage to the detector shell and even making the internal components unable to function normally.

[0004] Therefore, in order to solve the above problems, a detector for detecting natural gas distribution is proposed. Utility Model Content

[0029] Example:

[0030] See also Figure 1 - Figure 4A detector for detecting natural gas distribution includes a protective shell 1 and a detector body 2. A accommodating chamber 101 is opened at the top of the protective shell 1. The detector body 2 is arranged inside the accommodating chamber 101. A screw rod 3 is rotatably connected to the bottom end of the inner wall of the protective shell 1. A threaded slider 4 is threadedly connected to the outside of the screw rod 3. Four rotating rods 5 are rotatably connected to the outside of the threaded slider 4. One end of the rotating rod 5 away from the threaded slider 4 is rotatably connected to a support rod 6. One end of the support rod 6 away from the rotating rod 5 is threadedly connected to a connecting sleeve 7. One end of the connecting sleeve 7 away from the support rod 6 is slidably connected to a guide wheel 8.

[0031] Specifically, the four rotating rods 5 are evenly distributed outside the threaded slider 4 , and the four supporting rods 6 are all penetrated and slidably connected with the protective shell 1 .

[0032] Specifically, one end of the support rod 6 close to the guide wheel 8 is fixedly connected with a spring 9 , and one end of the spring 9 away from the support rod 6 is fixedly connected to one end of the guide wheel 8 . The spring 9 is arranged inside the connecting sleeve 7 .

[0033] Specifically, the interior of the protective shell 1 is fixedly connected with a support plate 103 , the top of the support plate 103 is fixedly connected with a motor 10 , the top end of the screw rod 3 passes through the bottom end of the support plate 103 , and is transmission-connected to the output end of the motor 10 .

[0034] In this solution, the motor 10 is used to drive the screw rod 3 to rotate. When the screw rod 3 rotates, the threaded slider 4 will slide up and down outside it, so that the support rod 6 can be extended outward or retracted inward by the rotating rod 5. In this way, the lengths of the four support rods 6 outside the protective shell 1 can be adjusted synchronously, and the guide wheel 8 can be used to enable the device to be smoothly lifted and lowered in tunnels of different diameters. At the same time, if there are protruding gravel in the tunnel, these gravel will squeeze the guide wheel 8, causing the guide wheel 8 to slide toward the inside of the connecting sleeve 7, thereby squeezing the spring 9. After being squeezed, the spring 9 will generate elastic force to offset the thrust of the guide wheel 8 from the gravel, which can not only reduce the shock of the equipment, but also make the equipment slide more smoothly inside the tunnel.

[0035] See also Figure 1 and Figure 4 The top edge of the accommodating chamber 101 is rotatably connected with an upper cover 102 , the top of the protective shell 1 is fixedly connected with a No. 1 fixing seat 11 , and the interior of the No. 1 fixing seat 11 is slidably connected with a sliding rod 12 .

[0036] Specifically, a second fixing seat 13 is fixedly connected to the top of the upper cover 102 , a limiting hole 131 is formed through one side of the second fixing seat 13 , and the sliding rod 12 is slidably connected to the limiting hole 131 .

[0037] Specifically, one end of the sliding rod 12 close to the second fixing seat 13 is fixedly connected with an elastic card ball 121, the minimum diameter of the elastic card ball 121 is smaller than the diameter of the limiting hole 131, and the maximum diameter of the elastic card ball 121 is larger than the diameter of the limiting hole 131.

[0038] In this solution, when the elastic card ball 121 is squeezed by the outside, it will shrink inward to make its overall diameter smaller. After installing the detector body 2, the staff can squeeze the elastic card ball 121 by hand to shrink it. After the elastic card ball 121 shrinks, it can pass through the limiting hole 131 normally. Then the staff releases their hands to restore the elastic card ball 121 to its original size. At this time, the elastic card ball 121 cannot pass through the limiting hole 131 freely, so that the upper cover 102 can be fixed on the protective shell 1. After the exploration is completed, the staff squeezes the elastic card ball 121 again and slides the sliding rod 12 away from the second fixing seat 13 to open the upper cover 102. In this way, not only can the upper cover 102 be firmly fixed on the protective shell 1 when the equipment is lowered in the tunnel, but it can also facilitate the staff to manually open the upper cover 102 to take and place the detector body 2, thereby improving the convenience of the device.

[0039] Working principle: before putting the device into the tunnel, the staff first places the detector body 2 inside the accommodating cavity 101, then flips the upper cover 102 to close the accommodating cavity 101, then the staff pinches the elastic card ball 121 with their hands and pushes the sliding rod 12 to send the sliding rod 12 into the limiting hole 131, and then the staff can release their hands, at which time the upper cover 102 is fixed, and then the staff turns on the motor 10 according to the overall diameter of the tunnel, thereby cooperating with the screw rod 3, the threaded slider 4 and the rotating rod 5 to adjust the length of the support rod 6 outside the protective shell 1, and finally the staff connects the device and the crane and puts it into the tunnel;

[0040] Inside the tunnel, if there are protruding gravel on the inner wall of the tunnel, these gravel will squeeze the guide wheel 8, causing the guide wheel 8 to slide into the connecting sleeve 7, thereby squeezing the spring 9. After being squeezed, the spring 9 will generate elastic force to offset the thrust of the guide wheel 8 from the gravel, which can not only reduce the shock of the equipment, but also make the equipment slide more smoothly inside the tunnel.

[0041] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
