DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1The utility model provides an embodiment: a gas turbine flowmeter detection device, including a detection device body 1, four groups of support legs are distributed in an array at the bottom of the detection device body 1, and the four groups of support legs play a role in stabilizing the support of the detection device body 1. A connecting pipe 2 is fixedly connected to the left side of the detection device body 1, and the gas passing through the flowmeter body 3 is transported to the detection device body 1 through the connecting pipe 2, so that the flowmeter body 3 is detected. The flowmeter body 3 can be installed and removed on the left side of the connecting pipe 2, and a clamping assembly 4 is arranged on the connecting pipe 2. Through the clamping assembly 4, it is convenient to install the flowmeter body 3 on the mounting flange 41, or to disassemble the flowmeter body 3. A supporting assembly 5 is arranged on the left side of the detection device body 1, and through the supporting assembly 5, the flowmeter body 3 is stably supported, avoiding manual support by the staff, and reducing the labor of the staff.

[0031] Reference Figure 1-Figure 3 The clamping assembly 4 includes a mounting flange 41, and a fixing block 46 is fixedly connected to the outer wall of the mounting flange 41, and the fixing blocks 46 are distributed in four groups in a circular array. The fixing effect of the fixing blocks 46 prevents the fixing blocks 46 from falling off. The outer periphery of the connecting pipe 2 is slidably connected to a movable ring 43, and the sliding effect of the movable ring 43 drives the hinged rod 44 to move. The outer wall of the movable ring 43 is hinged with a hinged rod 44, and the hinged rod 44 is distributed in four groups in a circular array. The moving effect of the hinged rod 44 drives the clamping rod 45 to rotate, and the left end of the hinged rod 44 is hinged with a clamping rod 45, and the clamping surface of the clamping rod 45 is a rubber surface.

[0032] Reference Figure 1 and Figure 4 The support assembly 5 includes a support plate 52, and a cylindrical rod 53 is penetrated and slidably connected to the inner wall of the top left end of the support plate 52. The sliding effect of the cylindrical rod 53 drives the arc plate 51 to move vertically. The top of the cylindrical rod 53 is fixedly connected to the arc plate 51. Handles are set on the front and back sides of the arc plate 51 to facilitate the staff to lift the arc plate 51. The flow meter body 3 is driven to move vertically through the moving effect of the arc plate 51.

[0033] Reference Figure 1 and Figure 2 An annular groove 48 is provided on the left side of the mounting flange 41, and a sealing ring 42 is provided on the inner wall of the annular groove 48. The sealing ring 42 is squeezed by the right side of the flow meter body 3 and the mounting flange 41, so that the sealing ring 42 expands and deforms, thereby sealing the gap between the flow meter body 3 and the mounting flange 41. An electric telescopic rod 47 is fixedly connected to the left side of the detection device body 1. The electric telescopic rod 47 is a prior art, and there are two groups of symmetrically distributed electric telescopic rods.

[0034] Reference Figure 1 and Figure 3 The right side of the mounting flange 41 is fixedly connected to the left end of the connecting pipe 2. The fixing effect of the mounting flange 41 prevents the mounting flange 41 from falling off. The inner wall of the fixing block 46 is hinged to the outer wall of the clamping rod 45. The clamping rod 45 can rotate around the hinge point through the hinge effect of the clamping rod 45, thereby clamping or releasing the flow meter body 3. The right side of the movable ring 43 is fixedly connected to the left end of the electric telescopic rod 47.

[0035] Reference Figure 1 and Figure 4 A fixing ring 54 is fixedly connected to the left end of the top of the support plate 52. The fixing effect of the fixing ring 54 prevents the fixing ring 54 from falling off. An insertion rod 55 passes through and is slidably connected to the left inner wall of the fixing ring 54. The insertion rod 55 can be plugged in or unplugged from the insertion hole 56 through the sliding effect of the insertion rod 55. A insertion hole 56 is opened on the left side of the cylindrical rod 53.

[0036] Reference Figure 1 The right side of the support plate 52 is fixedly connected to the left side of the detection device body 1. The fixing effect of the support plate 52 prevents the support plate 52 from falling off. The top of the arc plate 51 contacts the bottom of the flow meter body 3. By placing the flow meter body 3 on the arc plate 51, the arc plate 51 supports the flow meter body 3.

[0037] Reference Figure 4 The inner wall of the fixing ring 54 is slidably connected to the outer periphery of the cylindrical rod 53, and the outer periphery of the insertion rod 55 is plugged into the inner wall of the insertion hole 56. Through the plugging effect of the insertion rod 55 and the insertion hole 56, the fixing ring 54 limits the cylindrical rod 53, so that the arc plate 51 remains fixed.

[0038] Working principle: When the gas turbine flowmeter needs to be inspected, the staff places the flowmeter body 3 on the arc plate 51, and uses the handle to lift the arc plate 51 upward to make the cylindrical rod 53 slide upward. When the flowmeter body 3 moves to the same horizontal line as the mounting flange 41, the staff slides the plug rod 55 to the right to connect the plug rod 55 with the socket 56, and at the same time limits the cylindrical rod 53, so that the arc plate 51 maintains a fixed support effect on the flowmeter body 3.

[0039] The staff starts two sets of electric telescopic rods 47, and the electric telescopic rods 47 drive the movable ring 43 to slide to the left along the outer circumference of the connecting pipe 2, and the movable ring 43 drives the four sets of hinged rods 44 to move, and the four sets of hinged rods 44 respectively drive the four sets of clamping rods 45 to rotate, so that the four sets of clamping rods 45 clamp and squeeze the right end of the flow meter body 3, so that the right side of the flow meter body 3 is tightly attached to the left side of the mounting flange 41, and at the same time, the sealing ring 42 is squeezed by the flow meter body 3 and the mounting flange 41, so that the sealing ring 42 expands and deforms, and the gap between the flow meter body 3 and the mounting flange 41 is sealed, so that the flow meter body 3 remains fixedly mounted on the mounting flange 41, which is convenient for detecting the flow meter body 3.

[0040] When the inspection of the flow meter body 3 is completed, the staff controls the electric telescopic rod 47 to retract, so that the movable ring 43 slides to the right, and drives the clamping rod 45 to rotate in the opposite direction through the hinged rod 44, thereby releasing the clamping and fixing effect of the flow meter body 3, and the staff slides the plug rod 55 to the left, so that the plug rod 55 releases the plug-in effect with the socket 56, and at the same time releases the limiting effect on the cylindrical rod 53, so that the cylindrical rod 53 slides downward, and drives the flow meter body 3 to slide downward through the arc plate 51, so that the staff can remove the flow meter body 3.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
