[0018] The technical scheme in the embodiment of the utility model will be clearly and completely described below combined with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] It should be noted that all the directionality indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directionality indications will also change accordingly.

[0020] In addition, the description such as "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0021] Furthermore, the technical solutions of the various embodiments of the present application can be combined with each other, but must be based on the fact that a person skilled in the art can realize it, and when the combination of technical solutions appears to be contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0022] The present application provides a pipeline detection periscope with convenient height adjustment.

[0023] As shown in Figures 1-3 The pipeline detection periscope with convenient height adjustment provided by the embodiments of the present application comprises a telescopic rod 10, a fixed support 20 arranged on the telescopic rod 10, a periscope body 30 connected with the fixed support 20, and a spring component, wherein the spring component is connected to the bottom end of the telescopic rod 10 and / or the bottom end of the periscope body 30.

[0024] In the present embodiment, the pipeline detection periscope with convenient height adjustment comprises a telescopic rod 10, a fixed support 20 arranged on the telescopic rod 10, a periscope body 30 connected with the fixed support 20, and a spring component, wherein the spring component is connected to the bottom end of the telescopic rod 10 and / or the bottom end of the periscope body 30. Therefore, in the present technical solution, the spring component is used, and the periscope body 30 can be moved up and down by exerting a downward force or an upward force by the personnel on the well, thereby improving the convenience.

[0025] Optionally, the spring component is a single gas spring or a double gas spring. Specifically, when the telescopic rod 10 is in a vertical state, the telescopic rod 10 is unfolded and placed in the detected pipeline, at this time a gravity G (composed of the weight of the telescopic rod 10 + the weight of the equipment + the weight of the gas spring (except the gas rod)) acts on the gas spring.

[0026] That is, F-G max ; wherein f max> 0; F > f max .

[0027] In free state, since F > f max The gas spring will be fully extended, so the cylinder is fully extended before being put into the pipeline.

[0028] After being put into the pipeline, the gravity G acts on the gas spring, since F-G < f max , the gas rod is still fully extended.

[0029] When the personnel on the well applies a downward pressure F1 to the telescopic rod 10, so that F-G+F1 > f max , the gas spring starts to shrink the center of the pipeline.

[0030] When the personnel on the well removes F1, the following state returns to F-G < f max , which is less than the friction force, and will be in a static state.

[0031] If the device is below the center of the pipeline, the personnel on the well needs to apply an upward pulling force F2 to the telescopic rod, so that F-G-F2 > f max .

[0032] Until the device is in the center of the pipeline, F2 is removed, and the following state returns to F-G < fmax, which is less than the friction force, and will be in a static state.

[0033] In the above embodiment, the telescopic rod 10 includes a plurality of coaxially sleeved rod bodies 11, and the fixed support 20 is connected to the lower end rod body 11. Exemplarily, the spring component can be installed on the lowermost rod body 11, and also can be installed on the lower end of the periscope body 30.

[0034] In other embodiments, the spring component is not limited to be a gas spring, but also can be a compression spring, a tension spring, and the like, and a damping mechanism can be realized, and a structure having the interactions of the spring force, the resistance, the gravity, and the external force to achieve the effect of random stopping can be used.

[0035] Please refer to Figure 2 , the fixed support 20 includes a sleeve part 21 and a mounting part 23 connected to the sleeve part 21, the sleeve part 21 is connected to the telescopic rod 10, the periscope body 30 is connected to the mounting part 23, and the sleeve part 21 has a sleeve hole 22 connected to the telescopic rod 10.

[0036] The installation part 23 is provided with a transverse through connecting hole 24, a connecting column of the periscope body 30 is arranged in the connecting hole 24, the installation part 23 is provided with a vertical fastening hole 25, the fastening hole 25 is connected with the connecting hole 24, and a fastener 26 is arranged in the connecting hole 24 and connected with the connecting column from the fastening hole 25.

[0037] In the embodiment, the fixing support 20 and the periscope body 30 are installed through the sleeve part 21 and the installation part 23, so that the stability during work can be improved. The fastener 26 can be fixed in the form of a plunger, a pin or a screw.

[0038] Optionally, the periscope body 3030 is a zoom camera, and in other embodiments, the periscope body 3030 can also be other types of image acquisition devices, which are not described herein.

[0039] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields within the concept of the present application, and the contents of the present application are included in the patent protection range of the present application.
