[0008] A fixing ring is sleeved on the outer side of the probe body near the tail end. A plurality of elastic support mechanisms are equidistantly installed on the fixing ring. The elastic support mechanism includes a stabilizing arm. One end of the stabilizing arm is connected to a hinge seat through a torsion spring, and the hinge seat is fixed to the fixing ring; the other end of the stabilizing arm is provided with an electric wheel.

[0009] The probe of the present application has a simple structure, low manufacturing cost, strong overall applicability, good protection performance, and the ability of autonomous walking. It can ensure that the camera module always maintains a stable state during the lowering or lifting process of the probe body, which is beneficial to collecting clearer image data inside the hole.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. The probe of this application has a simple structure, low manufacturing cost, strong overall applicability, good protection performance, and has the ability of autonomous walking. During the process of lowering or lifting the probe body, it can ensure that the camera module can always maintain a stable state, which is beneficial to collecting clearer image data of the hole interior. At the same time, it can avoid the situation that the probe body and the camera module collide with the inner wall of the drilling hole, which is beneficial to extending the overall service life;

[0021] 2. In this application, a fixing ring is sleeved outside the probe body, and a plurality of elastic support mechanisms are circumferentially and evenly connected to the outside of the fixing ring, so that the probe body can be stably supported in the central area inside the drilling hole.

[0022] 3. The lower end of the stabilizing arm of this application is rotatably connected to the inside of the hinge seat through a rotating shaft, and two torsion springs are relatively sleeved at both ends of the rotating shaft. The two torsion springs can be used to provide an elastic support force in the direction away from the probe body to the stabilizing arm. In this way, the outer end of the stabilizing arm can always be in a propped-up state and have a certain elastic change range. Therefore, not only can the probe body be positioned and supported at a certain position in the drilling hole by a plurality of elastic support mechanisms, but also the elastic support mechanisms can adapt to the support requirements of different drilling hole diameters. Moreover, in the working condition where there are sundries or mud in the hole, this application can improve the overall passability through the change of the elastic amplitude, further enhancing the stability and reliability during the lowering or lifting process;

[0023] 4. An electric wheel is installed at the upper end of the stabilizing arm of this application, and an integrated control module is installed in the middle of the stabilizing arm, and the integrated control module is electrically connected to the electric wheel. This facilitates controlling the integrated control module through wireless communication to drive the electric wheel. Thus, while the elastic support mechanism has the elastic support ability, it can also have the ability to walk autonomously, so that the lowering and lifting actions can be automatically completed, which helps relevant personnel observe the environment at different positions inside the drilling hole.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them.

[0032] It should be noted that the number of the mounting grooves 9 is the same as the number of the elastic support mechanisms 14, and the specific number is determined according to the actual situation, which is not limited in this application. The number shown in the drawings of this application is three, that is, both the mounting grooves 9 and the elastic support mechanisms 14 are provided in three groups, but it cannot be understood as a limitation to this application, and it is only one of the preferred implementation manners given in this application.

[0033] As Figure 3 shown, in order to enable the hinge seat 3 to be firmly installed on the circumference of the fixing ring 2 by means of limit engagement, the number of the elastic support mechanisms 14 is three, and three mounting grooves 9 are evenly opened on the circumference of the fixing ring 2. The three hinge seats 3 in the three elastic support mechanisms 14 are correspondingly fixedly installed in the three mounting grooves 9. As a preferred method, in order to further improve the overall stability and reliability, the hinge seat 3 is fixedly connected to the fixing ring 2 by multiple bolts.

[0034] As a preference, a connecting gasket is embedded between the hinge seat 3 and the mounting groove 9.

[0035] Referring to Figure 1 , Figure 2 and Figure 3 , in order to ensure that the fixing ring 2 can be more stably sleeved on the probe body 1, a limiting ring 10 is further included. A pair of limiting rings 10 are respectively located at the upper end and the lower end of the fixing ring 2, and the fixing ring 2 is installed outside the probe body 1 for limiting the fixing ring 2.

[0036] Referring to Figure 1 , in order to enable the probe to have an illumination function, an illumination module is embedded and installed around the camera module 13, and the power supply cable connected to the illumination module passes through the wire channel and is connected to the connector 11.

[0037] In order to enable the integrated control module to communicate and connect with an external remote control device in a wireless communication manner, and at the same time, in order to enable the integrated control module to have a mobile power supply ability, a storage battery, a controller and a wireless communication module are arranged inside the integrated control module 8, and the controller is respectively connected to the storage battery and the wireless communication module.

[0038] Referring to Figure 1 , Figure 2 and Figure 3 , the elastic support mechanism 14 is circumferentially and uniformly distributed on the outer circumferential surface of the fixing ring 2, and specifically includes a hinge seat 3, a stabilizing arm 4, an electric wheel 7, an integrated control module 8 and a pair of torsion springs 6;

[0041] As a further preference, the anti-slip ring can adopt a hollow silica gel ring, which can not only effectively increase the friction, but also enable the electric wheel 7 to have a certain buffering effect, further improving the stability of the probe body 1 during the lowering or lifting process. At the same time, it is beneficial to improve the passing performance of the electric wheel 7.

[0042] The specific operating principle of this application is as follows:

[0043] During use, insert the cables of the external power supply and the external terminal into the cable connection hole 12 to establish the power supply and communication connections between the camera module 12 and the lighting module and the outside world through the connector 11; establish a wireless communication connection between the remote control device and the multiple integrated control modules 8;

[0044] Place the probe body 1 in the drill hole. Under the elastic action of multiple pairs of torsion springs 6, the outer ends of the multiple elastic support mechanisms 14 move away from the probe body 1, so that multiple electric wheels 7 in the multiple elastic support mechanisms 14 are all abutted against the inner wall of the drill hole, thereby suspending the probe body 1 inside the drill hole.

[0045] Use the remote control device to simultaneously control the integrated control modules 8 in the multiple elastic support mechanisms 14 to supply power to the corresponding electric wheels 7, so that the multiple electric wheels 7 rotate synchronously to slowly lower the probe body 1 deep into the drill hole, or can also drive the probe body 1 to slowly lift towards the drill hole opening. During the lowering or lifting process, use the camera module 13 to collect the images inside the drill hole in real time and transmit them to the external terminal in real time through the communication cable.
