[0038] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0039] Embodiment:

[0040] Referring to Figure 1 and Figure 2 , the embodiment discloses a liquid level gauge dismounting device, which comprises support plates 10, telescopic pieces 20 and locking pieces 30. Among them, the support plates 10 have two, and can be connected into one under the action of the locking pieces 30, and the telescopic pieces 20 have two and are matched on the two support plates 10 respectively.

[0041] Specifically, the support plate 10 is a rectangular structure, and one side of the support plate 10 has a notch 11, and the positions of the notches 11 on the two support plates 10 are mirror image distributed, so that the two notches 11 can form a through hole after the two support plates 10 are combined, and the through hole is used to place the liquid level gauge.

[0042] After the two support plates 10 are combined, the two telescopic pieces 20 are located on the same side of the two support plates 10, and the telescopic directions of the two telescopic pieces 20 are the same and are perpendicular to the plate surface of the support plate 10.

[0043] In the operation process of the technical solution, two support plates 10 are inserted between the liquid level meter flange and the washing tower flange from both sides of the liquid level meter, and the notches 11 of the two support plates 10 are opposite to the liquid level meter, then the locking member 30 is used to drive the two support plates 10 to move close to each other, and the liquid level meter is located in the through hole.

[0044] When the two support plates 10 are combined, the two telescopic members 20 are located between the liquid level meter flange and the washing tower flange, and the telescopic members 20 are in contact with the washing tower flange. Then the telescopic members 20 are driven to elongate, thereby driving the two support plates 10 to move away from the washing tower, so that the support plates 10 drive the liquid level meter to move to the outside of the washing tower.

[0045] Through the technical solution, the integrity of the liquid level meter can be effectively protected, so that the liquid level meter can be used again after being removed.

[0046] In one specific embodiment:

[0047] The notch 11 on the support plate 10 is a semicircular structure, and the notches 11 on the two support plates 10 form a complete circular through hole after being combined. The circular through hole mainly matches the outer contour of the liquid level meter, and can increase the contact area between the support plate 10 and the liquid level meter flange, thereby reducing the pressure between the support plate 10 and the liquid level meter flange, and achieving the purpose of enhancing the structural stability.

[0048] In another specific embodiment:

[0049] The support plate 10 has a slope surface 12, and the aforementioned notch 11 is also located on the slope surface 12. By providing the slope surface 12, the thickness of the support plate 10 at the notch 11 can be reduced, thereby facilitating the insertion of the support plate 10 between the liquid level meter flange and the washing tower flange.

[0050] Preferably, the support plate 10 has an action part 13, and the slope surface 12 and the notch 11 are located on the action part 13, wherein the action part 13 is a structure with a right triangle cross section on the support plate 10, and one angle of the triangular structure is an acute angle, and the acute angle is located on the notch 11.

[0051] Through the design, the notch 11 of the support plate 10 can be in the shape of a shovel, thereby being directly inserted into the gap between the liquid level meter flange and the washing tower flange.

[0052] In another specific embodiment:

[0053] The support plate 10 has a strip-shaped slot 14 arranged on the same side of the acting part 13, and the above-mentioned telescopic part 20 is arranged in the strip-shaped slot 14. By designing the strip-shaped slot 14, the thickness of the whole dismounting device can be reduced, and the support plate 10 cannot be inserted between the liquid level meter flange and the washing tower flange due to the telescopic part 20.

[0054] In another specific embodiment,

[0055] The telescopic part 20 comprises a sliding block 21, a support rod 22, a support block 23 and a screw rod 24. The screw rod 24 is arranged in the strip-shaped slot 14, and the two ends of the screw rod 24 are rotatably connected with the two sides of the support plate 10, and the screw threads on the two ends of the screw rod 24 are in opposite directions.

The two sliding blocks 21 are respectively provided with a threaded hole, and the screw threads of the two threaded holes are in opposite directions. The two sliding blocks 21 are matched with the two ends of the screw rod 24.

[0057] The support rod 22 has four, and the end of one support rod 22 on the two sides of each sliding block 21 is rotatably connected, and the other end of the four support rods 22 is rotatably connected on the two sides of the two ends of the support block 23.

[0058] In the operation process, when the telescopic part 20 enters between the liquid level meter flange and the washing tower flange, the rotation of the screw rod 24 can make the two sliding blocks 21 close to each other, and then the support block 23 is lifted up through the support rod 22, and the support plate 10 and the liquid level meter are driven away from the washing tower.

[0059] Preferably, one end of the screw rod 24 penetrates from one side of the support plate 10 and is rotatably connected with the support plate 10. A driving rod 25 is further arranged on the end of the screw rod 24 penetrating the support plate 10, and the driving rod 25 and the screw rod 24 form a T-shaped structure. By arranging the driving rod 25, the rotation force of the screw rod 24 can be reduced.

[0060] In another specific embodiment,

[0061] The two sides of the support plate 10 are further provided with a connecting block 31, and the side of the two connecting blocks 31 is aligned with the side of the support plate 10 having the notch 11. The connecting block 31 has a through hole, and the connecting blocks 31 on the two support plates 10 are matched.

[0062] The locking part 30 comprises a bolt 32 and a nut 33. The bolt 32 penetrates the connecting blocks 31 on the same side of the two support plates 10 and matches a nut 33. By means of the bolt 32 and the nut 33, the connecting blocks 31 can drive the two support plates 10 to approach each other.

[0063] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as a limitation on the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
