[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] In order to solve the technical problem in the prior art that when the support member needs to be adjusted to a horizontal state, it is necessary to adjust the depth of one or more fixed cones inserted into the soil, which is time-consuming and labor-intensive, and the soil is loose and not stable enough after adjustment, the utility model provides an angle adjustment device for an underground detector, which can quickly adjust the horizontal state of the support member from multiple angles so that the support member is parallel to the horizontal plane, wherein the support member is a component for fixing the detector. When the support member is in a state parallel to the horizontal plane, the detector connected to the bottom of the support member is convenient to use the horizontal plane as the reference plane, and it is convenient to adjust or calculate the rotation angle of the detector later, so as to facilitate the detector to detect the underground well.

[0024] It should be noted that the angle adjustment device described in the utility model is used for but not limited to downhole detectors, etc. For the convenience of explanation, in the utility model, only the application of the angle adjustment device to downhole detectors is used as an example for explanation, and the principle of applying the angle adjustment device to other types of equipment is essentially the same as the principle applied to downhole detectors, which will not be repeated here.

[0025] See also Figure 1 , Figure 1The present invention is a schematic diagram of the structure of an angle adjustment device for an underground detector in an embodiment of the present invention. The angle adjustment device includes a support assembly 1 and a plurality of adjustment assemblies 2. The support assembly 1 includes a first support member 11 and a second support member 12. The second support member 12 is used to connect the detector. The first support member 11 is used to be fixed to the wellhead of the underground well to support the detector and prevent the detector from falling into the underground well. Both ends of each adjustment assembly 2 are respectively connected to the first support member 11 and the second support member 12. Each adjustment assembly 2 can drive the second support member 12 to rotate relative to the first support member 11 to a horizontal state. Since the wellheads of some underground wells are in a non-horizontal state, the detector is arranged on the second support member 12. Therefore, in order to ensure that the initial position of the detector is in a horizontal position, the second support member 12 needs to be adjusted to a state parallel to the horizontal plane. The staff can selectively control one or more adjustment assemblies 2 according to the actual working conditions to drive the second support member 12 to a state parallel to the horizontal plane. A bubble level indicator may be provided on the second support member 12, and whether the second support member 12 is parallel to the horizontal plane, that is, in the horizontal plane state, can be judged by manually observing whether the bubble of the bubble level indicator is in the middle position.

[0026] In one embodiment, see Figure 1 The adjustment assembly 2 includes a driving member 21 and a movable member 22. The driving member 21 is disposed on the first support member 11. The two ends of the movable member 22 are respectively connected to the driving member 21 and the second support member 12. The driving member 21 can drive the movable member 22 to rotate, so that the movable member 22 drives the second support member 12 to rotate relative to the first support member 11, thereby adjusting the angle of the second support member 12 so that the second support member 12 is parallel to the horizontal plane. In this embodiment, there are many embodiments of the driving member 21 and the movable member 22, such as shown in the following embodiments.

[0027] In one embodiment, see Figure 1 The movable member 22 includes a first connecting rod 221 and a second connecting rod 222. One end of the first connecting rod 221 is connected to the driving member 21, and the other end of the first connecting rod 221 is rotatably connected to one end of the second connecting rod 222. The other end of the second connecting rod 222 is rotatably connected to the second supporting member 12. In this embodiment, the first connecting rod 221 is controlled to rotate by the driving member 21, the first connecting rod 221 drives the second connecting rod 222 to rotate, and the second connecting rod 222 drives the second supporting member 12 to rotate, thereby adjusting the angle of the second supporting member 12.

[0028] In one embodiment, see Figure 1The adjustment assembly 2 further includes a fixing seat 23 disposed on the second support member 12, the fixing seat 23 is provided with a ball groove (not shown in the figure), and a ball 223 is disposed at the end of the second connecting rod 222 away from the first connecting rod 221, and the ball 223 is rotatably embedded in the ball groove. It can be understood that the ball 223 is rotatably engaged with the ball groove, so that the second connecting rod 222 is not only rotatably connected to the fixing seat 23 through the ball 223, but the second connecting rod 222 can also pull the fixing seat 23, which is equivalent to pulling the second support member 12. When the driving member 21 drives the first connecting rod 221 and the second connecting rod 222 to rotate, the second connecting rod 222 drives the second support member 12 to rotate by rotating the ball 223 and embedding it in the ball groove. In this embodiment, the second connecting rod 222 is convenient to drive the second support member 12 to rotate from multiple directions through the rotational engagement of the ball and the ball groove.

[0029] In one embodiment, see Figure 1 The driving member 21 is a steering gear, which is rotatably connected to the first connecting rod 221 and can drive the first connecting rod 221 to rotate relative to the steering gear. The steering gear has a certain buffering effect and can slowly control the rotation of the first connecting rod 221, which is easy to operate.

[0030] In another embodiment, the adjustment component 2 includes a driving cylinder and a telescopic rod, one end of the telescopic rod is connected to the driving cylinder, and the other end of the telescopic rod is rotatably connected to the second support member 12. The driving cylinder can drive the telescopic rod to reciprocate and retract, so that the telescopic rod drives the second support member 12 to rotate relative to the first support member 11. In this embodiment, the driving cylinder is used to replace the steering gear of the previous embodiment, and the telescopic rod is used to replace the first connecting rod 221 and the second connecting rod 222 of the previous embodiment, and the telescopic rod is rotatably connected to the ball. When the driving cylinder drives the telescopic rod to reciprocate and retract, since the other unmoved adjustment components 2 pull other parts of the second support member 12, and the telescopic rod is rotatably connected to the second support member 12, the telescopic rod of the adjustment component in motion can drive the ball to rotate in the ball groove of the fixed seat 23 when reciprocating and retracting, thereby driving the second support member 12 to rotate.

[0031] In one embodiment, see Figure 1 , multiple adjustment components 2 are evenly arranged around the circumference of the support component 1, which can also be understood as multiple adjustment components 2 are evenly arranged around the circumference of the first support member 11 or the second support member 12. Figure 1The illustrated embodiment has three adjustment components 2, and the three adjustment components 2 are evenly arranged circumferentially, and one or more of the adjustment components 2 can be controlled to drive the second support member 12 to rotate until the second support member 12 is in a horizontal plane state. In other embodiments, the number of adjustment components 2 can also be set to two, four or more than four, and no excessive restrictions are made here. When there are two adjustment components 2, the straight line where the two fixing seats 23 of the two adjustment components 2 are located needs to pass through the center line of the second support member 12, so that the second support member 12 can be in a horizontal plane state when the two adjustment components 2 are controlled. When there are four or more adjustment components 2, multiple adjustment components 2 can be evenly arranged around the circumference of the angle adjustment device.

[0032] In one embodiment, see Figure 2 The first support member 11 includes a fixed plate 111 and a plurality of hooks 112. The fixed plate 111 is connected to the ends of the plurality of adjustment components 2 away from the second support member 12. One end of the plurality of hooks 112 is connected around the circumference of the fixed plate 111, and the other end of the plurality of hooks 112 is used to hook the wellhead. In other embodiments, the structure of the first support member 11 can also be consistent with the structure of the second support member 12, both of which are cylindrical plates. An additional fixed plate 111 can be connected to the top surface of the first support member 11. The hooks 112 are evenly arranged on the circumference of the fixed plate 111. The hooks 112 are hung on the wellhead to support the detector downhole.

[0033] In one embodiment, see Figure 2 The fixing plate 111 is provided with a plurality of through-holes 113 for reducing weight, which are conducive to reducing the weight of the fixing plate 111 for easy carrying. In addition, the holes 113 can be used to observe whether the bubble level indicator on the top surface of the second support member 12 is in a horizontal state.

[0034] In one embodiment, see Figure 2 The hook 112 is Z-shaped, and the end of the hook 112 is detachably connected to the fixed plate 111 by a screw, so as to facilitate the disassembly and replacement of the hook 112. The other end of the hook 112 can be directly hung on the top surface of the wellhead, which is convenient to use. In other embodiments, the first support member 11 can also be directly connected to the crane, and the entire angle adjustment device can be driven to rise and fall by the crane, so as to directly adjust the height of the detector. In other embodiments, a telescopic mechanism can also be provided on the side of the second support member 12 facing away from the first support member 11, and the detector is connected by the telescopic mechanism to adjust the height of the detector. It should be emphasized that the detector of the present application can be but is not limited to a camera, an infrared probe or an ultrasonic sensor, etc.

[0035] In order to better understand the present invention, the following Figure 1 to Figure 2 The technical solution of the utility model is described in detail:

[0036] The second support member 12 of the utility model is used to connect the detector, or indirectly connect the detector through a lifting mechanism. Before the detector is used, it is necessary to detect whether the second support member 12 is in a horizontal state to ensure that the detector is adjusted on the basis of the horizontal plane, so as to facilitate the detection of the working condition of the underground well through the detector. In the process of adjusting the second support member 12, it is possible to observe whether the bubble of the bubble level display on the second support member 12 is in the exact center position, so as to decide to control the corresponding one or more adjustment components 2, so that the second support member 12 rotates in different directions until the bubble of the bubble level display is in the exact center position. At this time, the second support member 12 is in a horizontal state, and then the detector is used to detect the underground well.

[0037] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
