[0029] In the field of engineering and construction, to ensure the stability of buildings and infrastructure, it is usually necessary to conduct regular settlement or level monitoring. Taking settlement monitoring as an example, during settlement monitoring, monitoring personnel need to stand at the benchmark and monitoring point respectively, and use the level instrument to obtain readings. Based on the readings, the settlement value is calculated to determine whether the settlement value meets the specified requirements.
[0030] However, in actual monitoring, the monitoring environment is constantly changing, especially in windy conditions, which can easily blow over or displace the leveling rod, affecting normal monitoring and reducing monitoring efficiency. The current monitoring operation method involves two monitoring personnel working together, one responsible for holding the leveling rod and the other for operating the leveling instrument, which results in high labor costs and increases monitoring costs.
[0031] Therefore, in order to enable monitoring to be carried out by a single person, the inventors of this application modified the structure of the monitoring points and leveling points during the pre-embedding process. Specifically, they set up a structure on the monitoring points and leveling points that cooperates with the leveling rod, so that the leveling rod can be fixed in place with the monitoring points and / or leveling points. This prevents the leveling rod from shifting or falling in windy conditions, thus eliminating the need for another person to hold the leveling rod and enabling effective measurement. This, in turn, improves monitoring efficiency and reduces monitoring costs.
[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.
[0033] like Figure 1 As shown, this application provides a displacement monitoring system, which can be used to monitor the offset and settlement of engineering structures such as flood control walls, flood control walkways, and buildings. Specifically, the displacement monitoring system includes at least a level instrument, a leveling rod 100, and a leveling point device 200. The leveling rod 100 includes a rod body 110 and a first magnetic suction element 120. The rod body 110 serves as the main component of the leveling rod 100 and supports other components on the leveling rod 100. A first mating feature 130 is provided at the lower part of the rod body 110, and the first magnetic suction element 120 is disposed adjacent to the first mating feature 130. A measuring scale can also be provided on the outer surface of the rod body 110 to facilitate the level instrument in measuring the corresponding values through the measuring scale.
[0034] The leveling device 200 includes a second mating feature 210 and a second magnetic attractor 220. The second mating feature 210 is adapted to the first mating feature 130, and the second magnetic attractor 220 is disposed adjacent to the second mating feature 210. Figure 4 As shown, when the leveling rod 100 is mounted on the leveling device 200 via the first fitting feature 130 and the second fitting feature 210, the first magnetic chuck 120 and the second magnetic chuck 220 are attracted together. In this way, by setting magnetic chucks on both the leveling rod 100 and the leveling device 200, and by using the mutually engaging first fitting feature 130 and second fitting feature 210, the leveling rod 100 can be positioned and fixed on the leveling device 200. This prevents the leveling rod 100 from shifting or falling in windy conditions, eliminating the need for another person to hold it, thus enabling effective measurement, improving monitoring efficiency, and reducing monitoring costs.
[0035] In this embodiment, the first magnetic 120 and the second magnetic 220 refer to two components that can be attracted to each other. The first magnetic 120 and the second magnetic 220 can both be made of magnets, or one of the first magnetic 120 and the second magnetic 220 can be made of a magnet and the other of the two can be made of a metal part that can be attracted by a magnet.
[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the first mating feature 130 can be constructed as a groove with a non-circular cross-section, and the second mating feature 210 can be constructed as a protrusion with a non-circular cross-section. The first mating feature 130 and the second mating feature 210 have the same shape; for example, both can be as shown in the diagram. Figure 3 The shape shown is a pentagon, or a triangle, quadrilateral, hexagon, etc.
[0037] In some other embodiments, the first mating feature 130 may also be configured as a protrusion with a non-circular cross-section, and the second mating feature 210 may be configured as a groove with a non-circular cross-section.
[0038] In some embodiments, such as Figure 5 and Figure 6 The displacement monitoring system may also include an observation point 300 located on the facility to be monitored, which has the same structure as the leveling device 200. In this way, monitoring personnel can position and fix the leveling rod 100 on the leveling device 200 by means of adsorption, just as described above. This allows for single-person operation of monitoring at both the observation point 300 and the leveling device 200.
[0039] Considering that the observation point 300 may be located on the top surface of the facility to be monitored (e.g., when the facility to be monitored is a flood control walkway), the observation point 300 may also be located on the side of the facility to be monitored (e.g., when the facility to be monitored is a tall building), in order to enable the displacement monitoring system of this application to adapt to both monitoring operations at the same time, in some embodiments, the first mating feature 130 has two parts, one of which is located at the bottom end of the ruler body 110, and the other is located on the side of the ruler body 110 and adjacent to the bottom end of the ruler body 110.
[0040] Thus, when the observation point 300 is located on the top surface of the facility to be monitored, the first mating feature 130 and the second mating feature 210 at the bottom of the ruler 110 can be used for positioning. When the observation point 300 is located on the side of the facility to be monitored, the first mating feature 130 and the second mating feature 210 on the side of the ruler 110 can be used for positioning.
[0041] Optionally, the two first mating features 130 may share the same first magnetic element 120. Of course, the two first mating features 130 may also each have their own first magnetic element 120.
[0042] In some embodiments, such as Figure 2 As shown, the leveling device 200 includes a protrusion that forms a second mating feature 210 and covers a second magnetic attractor 220.
[0043] Taking the first magnetic component 120 as a magnet and the second magnetic component 220 as an ferrous metal component as an example, the aforementioned protrusion not only forms the second mating feature 210, but also, by covering the second magnetic component 220, protects it from rain or moisture, serving as a rust-proof component. Optionally, the protrusion can be made of stainless steel or plastic.
[0044] In some embodiments, please refer again Figure 1 As shown, the top of the ruler body 110 is provided with a grinding element 140. The grinding element 140 can be a file or a component with several protrusions. During the monitoring operation, since the leveling device 200 and the observation point 300 are always exposed to the external environment, they inevitably become contaminated with some mud or other dirt that is difficult to clean. This dirt will affect the positioning and mating of the first mating feature 130 and the second mating feature 210. At this time, the grinding element 140 can be used to rub the dirt, so that the dirt can be removed from the leveling device 200 or the observation point 300.
[0045] In other embodiments, such as Figure 7 As shown, the leveling rod 100 may also include a rod body 110 and a fitting sleeve 400. The fitting sleeve 400 is interference-fitted to the bottom end of the rod body 110 by insertion. Correspondingly, a first magnetic suction element 120 and a first mating feature 130 are provided on the fitting sleeve 400. In this way, the fitting sleeve 400 can be used as a separate accessory, which can be connected to the rod body 110 to achieve the functions described above when needed.
[0046] On the other hand, this application also provides a leveling device 200, which is used to cooperate with and fix a leveling rod 100. The leveling device 200 includes a protrusion and a second magnetic member 220. The cross-section of the protrusion is non-circular, and the second magnetic member 220 is covered by the protrusion.
[0047] It should be noted that the specific structure of the leveling device 200 can be found in the detailed description above, and will not be repeated here.
[0048] On the other hand, this application also provides a leveling rod 100 for monitoring the displacement of a facility to be monitored. The leveling rod 100 includes a rod body 110 and a first magnetic suction member 120. The lower part of the rod body 110 is provided with a first mating feature 130, and the first magnetic suction member 120 is disposed adjacent to the first mating feature 130.
[0049] It should be noted that the specific structure of the leveling rod 100 can be found in the detailed description above, and will not be repeated here.
