[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1 , which is the first embodiment of the utility model, and this embodiment provides a fixing mechanism, including a base 100. The base 100 is narrow in shape and can reach places in the gap of the turbine unit that workers cannot pass through. A column 101 is arranged in the middle of the base 100 and is perpendicular to the plane thereof. The column 101 is fixed on the base 100 and is square in shape, so that the adjusting member 201 can be displaced along the column 101, but cannot be rotated.

[0039] Furthermore, the adjustment component 200 is arranged on the outside of the column 101, including an adjustment member 201, a movable column 201a with a column hole in the middle of the adjustment member 201, so that the column 101 can pass through the column hole and move in coordination with the adjustment member, an outer groove 201b is arranged at one end of the movable column 201a, and a control key 203b-1 on the adjustment claw 203b arranged on the control member 203 is cylindrical, inserted into the outer groove 201b, and tangent to the outer groove 201b, a driving shaft 203a is arranged at one end of the adjustment claw 203b, and is coaxially fixedly connected with the rotating shaft of the second driving motor 103, when the second driving motor 103 is turned on, it can drive the driving shaft 203a to rotate, further change the rotation angle of the adjusting claw 203b, change the tangent position of the control key 203b-1 and the outer groove 201b, and control the position of the adjustment member 201 on the column 101 to adjust.

[0040] Furthermore, an inner groove 201c is provided at the other end of the adjusting member 201, and the rotating member 204 is composed of a connecting rod 204c, a bent rod 204a fixed to one end of the connecting rod 204c, and a folding plate 204b fixed to the other end of the connecting rod 204c. A limiting ball 204a-1 is provided at the bent end of the bent rod 204a, and the limiting ball 204a-1 extends into the inner groove 201c and is tangent to the inner groove 201c. When the adjusting member 201 moves up and down on the column 101, the position of the inner groove 201c is adjusted. The position of the adjusting member 204 changes, at this time the lifting rod 202 does not move, only the connecting rod 204c of the adjusting member 204 rotates in the sleeve 202a set at the end of the lifting rod 202, so the vertical height of the sleeve 202a remains unchanged, the position of the inner groove 201c changes, and the position of the limiting ball 204a-1 changes relative to the sleeve 202a, so that the rotating member 204 rotates with the connecting rod 204c as the axis, and the folding plate 204b follows the rotation, thereby making the clamping assembly 300 on the folding plate 204b realize the change of the pitch posture.

[0041] Furthermore, a first drive motor 102 is fixedly arranged on the base 100, and the rotation of the first drive motor 102 is fixedly connected to one end of the lifting rod 202. When the first drive 102 is turned on, the lifting rod 202 rotates accordingly, and the opening of the ring 202 at the other end of the lifting rod 202 rotates, so that the upper bent rod 204a of the rotating member 204 rotates horizontally. At this time, the limiting ball 204a-1 rotates in the inner groove 201c, realizing the change of the clamping assembly 300 rotating with the lifting rod 202 as the axis.

[0042] In summary, this design changes the direction faced by the clamping component 300 by rotating and lowering the adjusting component 200, making it easier for the collection terminal to collect and alarm the operating parameters of the turbine unit.

[0043] Example 2

[0044] Reference Figures 1 to 4 , which is the second embodiment of the utility model, includes all the contents of the embodiment, and the clamping assembly 300 fixed on the folding plate 204b. The collection terminal is quickly clamped by the clamping assembly 300, so that the staff can easily collect and alarm the operating parameters of the turbine unit.

[0045] Furthermore, the clamping assembly 300 includes a tightening ring 302, which is composed of a tightening section 302a and a contact section 302b. The tightening section 302a and the contact section 302b are connected to form a closed loop. The tightening end 302a is fixed on the surface of the folding plate 204b, and a shell 301 is provided outside the contact section 302b, and the shell 301 can move along the contact section 302b.

[0046] Furthermore, a bolt hole 301 a is provided in the middle of the housing 301 , and ring holes 301 b are provided on both sides of the bolt hole 301 a . The housing 301 is displaced on the tightening ring 302 through the ring control 301 b .

[0047] Preferably, a lever groove 302a - 1 is provided on the side wall of the tightening section 302a , one end of the lever 303 extends into the lever groove 302a - 1 , and an extrusion plate 302a - 2 is provided on the side wall opposite to the side wall where the lever groove 302a - 1 is located, for extruding the return spring 304 .

[0048] Preferably, one end of the return spring 304 abuts against the extrusion plate 302a-2, and the other end abuts against the inner wall of the housing 301. When the clamping assembly 300 is effective, the return spring 304 is compressed by the extrusion plate 304, and can be reset to the initial state when the clamping assembly 300 fails.

[0049] Furthermore, the center position of the lever 303 is rotatably connected to the inner wall of the shell 301, and the lever 303 rotates in place with its center as the axis. One end of the lever 303 is inserted into the lever groove 302a-1, and the other end is inserted into the I-bolt 305. Through the movement of the I-bolt 305 in the middle bolt hole 301a, one end of the lever 303 is pushed, and the other end of the lever 303 drives the tightening section 302a to contract or relax the relative position of the shell 301 and the contact section 302b, thereby clamping and releasing the acquisition terminal.

[0050] Furthermore, the I-bolt 305 passes through the bolt hole 301 a and is threadedly connected to the nut 306 .

[0051] In summary, this design achieves the clamping of the middle collection terminal by changing the relative position of the outer shell and the tightening ring, and changes the posture of the collection terminal by adjusting the components, so that the collection terminal can observe and collect operating parameters of the turbine units at different angles.

[0052] Example 3

[0053] Reference Figures 1 to 4 , which is the third embodiment of the utility model, and further provides a movable platform for unit operation parameter alarm. The platform is arranged below the base 100, mainly to provide a bearing platform and transportation for the adjustment component 200 and the clamping component 300, including a moving part 400, which is composed of a plurality of universal wheels 401.

[0054] Preferably, the movable part 400 can transmit instructions through a remote control system on the market, such as a remote control car on the market, through a handheld remote control. A receiver is set on the platform to receive the control instructions of the handheld remote control, so that the platform can be moved to a place that the staff cannot reach to collect the operating parameters of the turbine unit.

[0055] In summary, this design facilitates the carrying and transportation of the data collection terminal, and makes it easier for staff to collect data at locations with tricky angles and spaces.
