Description

Technical Field

[0001] The invention relates to the field of soil improvement assessment, and in particular to a soil improvement assessment display stand for a power transmission line project and a use method thereof. Background Art

[0002] Transmission line engineering refers to the construction of transmission lines. Transmission engineering construction as a whole belongs to the construction and installation industry, which is one of the main ways to produce carbon. How to quantify the ecological carbon sequestration capacity of transmission line engineering under current conditions and clarify the carbon sequestration contribution of soil improvement measures in disturbed areas of power grid construction projects is one of the tasks that can be clarified in current power grid projects.

[0003] When evaluating the soil improvement of a power transmission line project, it is necessary to display the evaluation process, results and other data. At present, a display board or display screen is generally used to display it. In the authorized Chinese utility model patent "Announcement No.: CN217902653U, Name: A Foldable Spliced ​​LED Large Screen", a group of sub-screens are slidably connected in the installation cavity to facilitate the folding of the sub-screens, and a certain protective effect is played on the folded sub-screens, and then the limit block is slid along the limit groove on the frame, so that the limit block and the card groove on the installation frame are engaged, which is convenient for fixing the folded position of the sub-screen to prevent it from sliding out. However, in the above application, the sub-screen only has a single contraction and extension function. After the sub-screen is extended, the area and volume of the upper part of the large screen are increased, and it is easy to tip over during the display process. In order to facilitate the movement of the display stand, wheels are generally provided for movement. When the display stand is in use, the contact area between the wheels and the ground is small, resulting in a small friction force. The display stand is easy to move and shake due to a small external force, affecting the display. Summary of the invention

[0043] The method of use includes the following steps:

[0044] Step 1: Use the mobile wheels to move the display stand to the designated area for use;

[0045] Step 2, unfold the secondary display board, start the two-way driving source, at this time, the two-way driving source drives the transmission shaft and the height adjustment stud to rotate respectively, when the transmission shaft rotates, it can drive the main bevel gear to rotate, and then drive the secondary bevel gear to rotate, at this time, it can drive the stud to rotate, when the stud rotates, it can drive the moving plate to move, and then drive the rotating parts to move in the same direction, at this time, it can drive the secondary display board to move in the same direction, and the secondary display boards on both sides move in opposite directions, so that the secondary display boards on both sides extend from the back of the main display board at the same time, and the secondary display board is unfolded, at this time, the soil improvement assessment data of the power transmission line project can be added to the display screen and the secondary display board respectively, and the display screen and the secondary display board are used to display the relevant process and results of the soil improvement assessment of the power transmission line project;

[0049] Step 6: While the linkage mechanism drives the auxiliary display board to be retracted, the anti-slip plate is away from the ground and the fixing plate is close to the supporting base to reduce the volume of the display stand.

[0050] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0051] The positive and progressive effects of the present invention are:

[0052] The present invention utilizes the retractable and extendable components to retract and extend the auxiliary display panels, thereby reducing the volume of the display stand, making it easier to use and store the display stand. The anti-skid components can automatically cling to the ground when the auxiliary display panels are extended, increasing the friction between the display stand and the ground, thereby increasing the stability of the display stand and preventing the display stand from tipping over easily when extended.

[0055] Furthermore, when the anti-slip plate is close to the ground, the angles of the auxiliary display board and the display screen can be changed, thereby changing the display angle of the display stand, solving the problem of difficult adjustment of the display angle;

[0130] When the height adjustment plate 72 moves, the moving rack 91 can be driven to move in the same direction, thereby driving the central gear 92 to rotate, and at this time, the side gear 93 can be driven to rotate, and then the lower gear 95 can be driven to rotate. When the lower gear 95 rotates, the connecting rack 96 can be driven to move, thereby driving the sliding plate 97 and the moving wheel 98 to move in the same direction, so that the connecting racks 96 on both sides can move toward or away from each other. When the auxiliary display board 2 is unfolded, the connecting racks 96 on both sides are unfolded, thereby increasing the support area of ​​the display stand and increasing the stability of the display stand.

[0131] In general, when the auxiliary display panel 2 is unfolded, the anti-skid component 7 is close to the ground, and the stabilizing component 9 is also unfolded. When the auxiliary display panel 2 is stored, the anti-skid component 7 is away from the ground, and the stabilizing component 9 is also stored.

[0132] The method of use includes the following steps:

[0133] Step 1: Use the moving wheels 98 to move the display stand to a designated area for use;

[0134] Step 2, unfold the secondary exhibition board 2, start the two-way driving source 81, at this time, the two-way driving source 81 drives the transmission shaft 82 and the height adjustment stud 71 to rotate respectively, when the transmission shaft 82 rotates, it can drive the main bevel gear 83 to rotate, and then drive the secondary bevel gear 84 to rotate, at this time, it can drive the stud 41 to rotate, when the stud 41 rotates, it can drive the moving plate 43 to move, and then drive the rotating parts to move in the same direction, at this time, it can drive the secondary exhibition board 2 to move in the same direction, and the secondary exhibition boards 2 on both sides move in opposite directions, so that the secondary exhibition boards 2 on both sides extend from the back of the main exhibition board 1 at the same time, and the secondary exhibition board 2 is unfolded, at this time, the soil improvement assessment data of the power transmission line project can be added to the display screen 3 and the secondary exhibition board 2 respectively, and the display screen 3 and the secondary exhibition board 2 are used to display the relevant process and results of the soil improvement assessment of the power transmission line project;

[0135] Step 3: When the height-adjusting stud 71 rotates, the height-adjusting plate 72 is driven to move downward along the anti-deflection track 78, thereby driving the follower column 73, the rotating component and the anti-slip plate 74 to move in the same direction. When the auxiliary display board 2 is unfolded, the anti-slip plate 74 is close to the ground. The anti-slip plate 74 is used as the main supporting force to support the display stand, reduce the pressure of the moving wheel 98, and use the anti-slip plate 74 to increase the friction between the display stand and the ground;

[0136] Step 4: When the anti-slip plate 74 supports the display stand, the support base 5 can be rotated by using the rotating block 75 and the fixing plate 76, so that the auxiliary display board 2 and the display screen 3 can be rotated to adjust the angles of the auxiliary display board 2 and the display screen 3;

[0137] Step 5: When the height adjustment plate 72 moves downward, it can drive the moving rack 91 to move in the same direction, thereby driving the central gear 92 to rotate, and then driving the side gear 93 to rotate, and then driving the support frame 94 to rotate, thereby driving the connecting rack 96 to move, and then driving the sliding plate 97 and the moving wheel 98 to move, so that when the auxiliary display board 2 is unfolded, it can drive the connecting rack 96 to move away from the supporting base 5, thereby expanding the supporting area of ​​the display stand;

[0138] Step 6: When the linkage mechanism 8 drives the auxiliary display board 2 to be retracted, the anti-slip plate 74 is away from the ground, and the fixing plate 76 is close to the supporting base 5, so as to reduce the volume of the display stand.
