Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of layered markers, in particular to a layered marker heating control device. BACKGROUND

[0002] The layered marker is a measuring device for monitoring soil deformation in engineering geology, which refers to a marker point buried in different soil layers of the overburden. The layered marker is vertically buried on the top and bottom plates of different soil layers in the ground subsidence area, and is protected by stability treatment. The layered marker can obtain parameters such as compression and expansion of each soil layer by joint measurement with the bedrock marker and other layered markers, and then calculate the soil deformation and total ground subsidence. When buried, the bottom sealed corrugated pipe is placed in the drill hole, and the guide pipe is inserted and pressed to the bottom of the hole at the same time. For deep burial, the corrugated pipe and the guide pipe need to be connected in sections. The interface is fixed with a magnetic material, and the initial reading is determined by the elevation of the guide pipe nozzle measured by the level gauge. The magnetic probe measures the position of each inductive coil from top to bottom.

[0003] However, we found in actual use that in a relatively cold environment, the moisture inside the layered marker is easy to freeze, causing the marker rod and the inner centralizer to freeze and stick together, so that the geological changes cannot be accurately transmitted to the monitoring system in time, affecting the measurement accuracy and data continuity, and further causing the monitoring data to deviate or even be interrupted. In severe cases, it may cause misjudgment risk. The existing solutions to this problem usually use external wrapping insulation materials or simple electric heating wire heating devices. However, this method undoubtedly increases the frictional resistance between the marker rod and the inner centralizer, affecting the normal sliding of the marker and the data acquisition accuracy. Therefore, we propose a layered marker heating control device. SUMMARY

At the same time, the heat insulation roller 162 set at the axis of the silicone cloth 163 will rotate outside the heat insulation shaft 161, and the heat insulation torsion spring 164 will automatically adjust the torque according to the change of the distance between the multiple placement plates 5, ensuring that the silicone cloth 163 always keeps tightly attached to the edge of the placement plate 5, effectively maintaining the sealing of the heating area. The upright plate 165 set outside the placement plate 5 can support the silicone cloth 163, so that the silicone cloth 163 prevents heat from overflowing from the connection between the upright plate 165 and the silicone cloth 163 during the expansion of the placement plate 5. At the same time, the high temperature resistance of the upright plate 165 itself can effectively block the heat conduction path. Its function is to ensure that the heat of the heating plate 7 is effectively constrained around the rod 4 during the heating process, minimizing heat loss and improving heating efficiency and energy utilization.

[0054] When the staff needs to heat the marker 4, first, the multiple placing plates 5 are sleeved outside the marker 4 and placed in the protection tube 1, then the auxiliary ring 114 is pulled to move upward, when the auxiliary ring 114 moves upward, the second telescopic tube 113 arranged on the auxiliary ring 114 slides outside the corresponding first telescopic tube 112 and gradually approaches the support ring 111 corresponding thereto, at this time, the auxiliary ring 114 drives the multiple driving plates 131 outside the auxiliary ring 114 to move upward together, so that the driving plates 131 slide in the driving grooves 132 in the fixed block 121, when the driving plates 131 slide in the driving grooves 132, the inclined surface at the top of the driving plates 131 exerts a pushing force on the bottom end of the extrusion plate 123, after the extrusion plate 123 is driven by the driving plates 131, the driving plates 131 with the inclined surface at the top transmit the force to the end of the extrusion plate 123 with the inclined surface in the process of sliding, so that the extrusion plate 123 slides in the extrusion groove 122 in the fixed block 121, at this time, the extrusion plate 123 gradually moves away from the marker 4, and the extrusion spring 125 arranged at one end of the extrusion plate 123 is also compressed to store energy, until the end of the extrusion plate 123 away from the marker 4 abuts against the inner wall of the protection tube 1, the groove 124 arranged at one end of the extrusion plate 123 can increase the friction between the extrusion plate 123 and the protection tube 1, so as to effectively prevent the heating plate 7 from being displaced or loosened during heating, and ensure the stability of the heating process, the extrusion plate 123 made of silicone rubber can effectively cooperate with the driving plates 131, when the staff no longer pulls the auxiliary ring 114, the extrusion spring 125 pushes the extrusion plate 123 to make it tightly adhere to the driving plates 131, and the extrusion plate 123 is stably positioned under the action of the friction of the silicone rubber, so as to prevent backtracking, the auxiliary ring 114 drives the multiple driving plates 131 to move upward at the same time, so that the multiple driving plates 131 synchronously push the corresponding extrusion plates 123 to move outward, so as to ensure that the forces at each point are uniform and the moving distances of the multiple extrusion plates 123 are the same, it should be noted that the auxiliary ring 114 has multiple first telescopic tubes 112 and second telescopic tubes 113, therefore, when the auxiliary ring 114 moves upward, the multiple first telescopic tubes 112 and second telescopic tubes 113 effectively guide the auxiliary ring 114 to move horizontally upward, so that the auxiliary ring 114 always maintains the horizontal state with the support ring 111, thereby ensuring that the multiple driving plates 131 arranged outside the auxiliary ring 114 have the same rising height, and driving the multiple extrusion plates 123 to slide outward by the same distance, and the extrusion spring 125 can ensure that the extrusion plate 123 always tightly adheres to the driving plate 131, further ensuring that the sliding distances of the multiple extrusion plates 123 will not have errors, so as to complete the center positioning of the multiple placing plates 5, avoid the offset of the placing plates 5 due to the inconsistent moving speed and length of the extrusion plates 123, and affect the heating uniformity;

[0055] After the positioning of the placing plate 5 is completed, if it is necessary to longitudinally assemble multiple placing plates 5, a group of placing plates 5 is aligned on top of a group of placing plates 5 below, the splicing grooves 82 at the bottom of the upper placing plate 5 are aligned with the splicing rods 81 at the top of the lower placing plate 5, then gently press down, so that the splicing rods 81 are embedded in the splicing grooves 82, the longitudinal connection of the two groups of placing plates 5 is completed, multiple groups of placing plates 5 are stacked in sequence, the stable extension of the overall structure is realized, it should be noted that multiple placing plates 5 in an array in a ring shape are a group, the quick alignment and connection between each group of placing plates 5 are realized through the close cooperation of the splicing rods 81 and the splicing grooves 82, the stacking process is stable and efficient, then the placing is carried out according to the above, the corresponding auxiliary ring 114 is driven, so that the corresponding extrusion plate 123 abuts against the inner wall of the protection tube 1, so as to accurately fix each group of placing plates 5 at the center position, the coaxiality and stability of multiple stacked groups are ensured;

[0056] After the assembly and positioning of multiple groups of placement plates 5 are completed, the heating plate 7 can be started to generate heat. Since the heating plate 7 and the placement plate 5 are not in contact with the marker 4, there will be no interference with the marker 4 during the heating process due to thermal expansion, effectively avoiding the risk of structural jamming or deformation. The heat is transferred to the outside of the marker 4 through air as the medium, and then uniformly radiates to the surrounding environment, achieving stable heating of the target area. When the size of the marker 4 is large and the spacing of multiple heating plates 7 needs to be adjusted, pull the transmission handle 158 upwards, which will drive the multiple limiting plates 155 at the bottom end to move upwards together, so that the multiple limiting plates 155 slide in the corresponding limiting frame 154. When the multiple limiting plates 155 move upwards simultaneously, the limiting plate 155 will drive the second traction plate 156 on one side to move upwards together. The limiting slot 157 opened on the outside of the inner centralizer 3 can avoid the limiting plate 155 being hindered during the movement process. When the multiple second traction plates 156 move upwards, they will gradually separate from the corresponding first traction plates 152. At this time, the multiple traction springs 153 start to exert force, pushing the corresponding first traction plates 152. The first traction plate 152 gradually moves away from the marker 4 under the push of the traction spring 153, thereby driving the corresponding transmission plate 151 to slide in the support ring 111. When the transmission plate 151 slides in the support ring 111, the traction shaft 1411 at one end will move together, causing the traction shaft 1411 to gradually move away from the marker 4. During the process of gradually moving away from the marker 4, i.e., gradually approaching the inner wall of the support ring 111, the opposite ends of the first connecting rod 143 and the second connecting rod 148 rotatingly arranged on the outside of the traction shaft 1411 will gradually approach the inner wall of the support ring 111 together with the traction shaft 1411. At this time, since the first sliding block 144 and the second sliding block 149 are slidingly arranged in the first sliding groove 145 and the second sliding groove 1410 respectively, when the opposite ends of the first connecting rod 143 and the second connecting rod 148 move together with the traction shaft 1411, the first rotating shaft 142 and the second rotating shaft 147 rotatingly arranged at the opposite ends of the first connecting rod 143 and the second connecting rod 148 will gradually separate, thereby causing the first rotating shaft 142 and the second rotating shaft 147 to push the corresponding first sliding block 144 and second sliding block 149 to slide. At the same time, the first rotating shaft 142 and the second rotating shaft 147 gradually moving away will pull the corresponding first sliding plate 141 and second sliding plate 146, causing the placement plate 5 to gradually approach the traction shaft 1411, thereby achieving the effect of the placement plate 5 gradually approaching the inner wall of the support ring 111, and realizing flexible adjustment of the spacing of the heating plate 7. The first sliding block 144 and the second sliding block 149 can effectively pull the placement plate 5 through the first sliding plate 141 and the second sliding plate 146 when the spacing between the first rotating shaft 142 and the second rotating shaft 147 changes, so that the placement plate 5 can move in the process of the first rotating shaft 142 and the second rotating shaft 147 separating,Follow the traction shaft 1411 together with the radial movement, adapt to different size of the heating demand of the marker 4;

[0057] When the plurality of heating plate 7 generates heat energy in the process, silica gel cloth 163 can effectively fill the gap between the plurality of placement plate 5, prevent heat loss, when the staff on the plurality of placement plate 5 spacing adjustment, set in the silica gel cloth 163 shaft center of the heat insulation roller 162 will rotate in the heat insulation shaft 161 outside, and the heat insulation torsion spring 164 will automatically adjust the torsion according to the spacing between the plurality of placement plate 5, ensure that the silica gel cloth 163 always keep close to the edge of the placement plate 5, effectively maintain the sealing of the heating area, set in the placement plate 5 outside the vertical plate 165 can be raised to the silica gel cloth 163, so that the silica gel cloth 163 in the process of expansion of the placement plate 5, avoid heat from the vertical plate 165 and silica gel cloth 163 connection place escape, while the vertical plate 165 itself can effectively block the heat conduction path of high temperature characteristics, set as the bevel of the placement slot 6 can effectively guide the installation position of the heating plate 7 in the process of installation, so that the heating plate 7 in the process of replacement, repair, assembly, can be quickly centered with the same shaft center of the placement plate 5, improve the staff repair, replacement, assembly efficiency;

[0058] The whole process, the operator can complete the heating plate 7 spacing precision adjustment by simple mechanical linkage, without the aid of external power device, both improve the adjustment efficiency, and reduce the equipment maintenance cost, silica gel cloth 163 and heat insulation roller 162 synergistic effect, while ensuring the sealing, reduce the heat loss, so that the heat energy concentrated on the surface of the marker 4, further improve the heating uniformity and energy utilization.
