Description

Technical Field

[0001] The utility model relates to the technical field of deformation monitoring sensors, in particular to a limiting mechanism and a deformation monitoring device. Background Art

[0002] Structural safety and health monitoring of water conservancy, hydropower and other construction projects mainly relies on the embedding of various deformation-based sensors. Large-scale projects require a large number of monitoring sensors, and sensor installation runs through the entire process of excavation, support, pouring, lining, and electromechanical installation.

[0003] The internal deformation of the monitored object includes various movements such as stretching, compression, shearing, and torsion. Although traditional sensors can simultaneously face the two-way movement of compression or stretching of the monitored object, this will cause inconsistent responses of the sensors in the two directions, resulting in deviations in measurement accuracy. The two-way movement makes the interpretation of monitoring data more complicated, and it is necessary to distinguish whether the deformation is caused by stretching or compression. In addition, traditional sensors rely on any wired or wireless data links, including cables, optical cables, radio waves, etc., to transmit monitoring data. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the problem that the above or existing devices may cause deviation in measurement accuracy due to the two-way movement of compression or stretching of the traditional sensor facing the monitored object, the present utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a limiting mechanism.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: the installation unit includes an outer cylinder and an inner cylinder arranged in the outer cylinder; the limiting unit includes a reset component arranged in the outer cylinder and an extrusion component on the inner cylinder.

[0008] As a preferred solution of the limiting mechanism of the present invention, the reset assembly includes a through hole provided in the outer cylinder, a compression groove provided in the through hole, and a spring provided on the inner wall of the compression groove.

[0009] As a preferred solution of the limiting mechanism of the present invention, wherein: a connecting arc plate is provided on the spring, and limiting teeth are provided on the connecting arc plate.

[0010] As a preferred solution of the limiting mechanism of the present invention, the limiting teeth penetrate the inner wall of the through hole and are movably connected in the through hole, and the limiting teeth form a linear array along the inner wall of the through hole.

[0011] As a preferred solution of the limiting mechanism of the present invention, the extrusion assembly includes rigid teeth arranged on the outer wall of the inner cylinder, an inclined surface arranged on the rigid teeth, and the rigid teeth and the limiting teeth cooperate with each other.

[0012] As a preferred solution of the limiting mechanism of the utility model, it also includes a pushing component, which includes an anchor plate arranged at the other end of the outer tube and one end of the inner tube, a receiving groove arranged at the outlet of the through hole, and a knife valve arranged in the receiving groove.

[0013] As a preferred solution of the limiting mechanism of the present invention, the blade of the knife valve faces downward and is aligned with the central axis of the wire.

[0014] The limiting mechanism of the present invention has the beneficial effect that by setting the limiting unit, the inner cylinder can slide in the outer cylinder and can only move in one direction, ensuring that the inner cylinder will not slide in the opposite direction during use, limiting the movement range of the inner cylinder so that it can only move in a predetermined direction.

[0015] Given that in actual use, there is still the problem that traditional sensors rely on any wired or wireless data links, including cables, optical cables, radio waves, etc., to transmit monitoring data.

[0016] In order to solve the above technical problems, the present invention also provides the following technical solution: the detection unit includes a measuring component arranged on the inner cylinder.

[0017] As a preferred solution of the deformation monitoring device of the present invention, the measuring component includes an entanglement storage unit arranged in the inner cylinder, a power retention unit arranged in the inner cylinder, and a wire arranged between the entanglement storage unit and the power retention unit.

[0018] As a preferred solution of the deformation monitoring device described in the present invention, the entanglement storage unit corresponds to an electric power retention unit, the electric power retention unit and the entanglement storage unit are connected by a wire to form a measuring component, and the measuring components are arranged along the axial direction of the inner cylinder into a linear array of several measuring components, and the interval between each measuring component is fixed at 0.1-1 mm.

[0019] The beneficial effects of the present utility model are as follows: through the detection component, when the monitored object undergoes internal tensile deformation, the inner tube is pulled along with the anchor plate. When the pulling interval reaches one measuring unit, a power supply unit wire will be cut off by the knife switch, and the observation station readings are accumulated to obtain the current deformation value inside the monitored object. The deformation monitoring sensor system device based on the quantum entanglement principle does not rely on any wired or wireless data link including cables, optical cables, radio waves, etc., and subversively solves the technical problems of reading and transmitting monitoring sensor data.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0032] Example 1

[0033] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a limiting mechanism that allows the inner cylinder 102 to slide in a single direction within the outer cylinder 101. The outer cylinder 101 and inner cylinder 102 are cylindrical in design, with diameters ranging from 10 mm to 20 mm and lengths ranging from 100 mm to 200 mm. Both the inner and outer cylinders 101 are made of a highly rigid metal material to ensure stability and durability in complex environments. The inner cylinder 102 is slidably connected to the outer cylinder 101 via a through hole 201a. While a certain gap exists between the inner cylinder 102 and the inner wall of the through hole 201a, the opening diameter of the through hole 201a is nearly identical to that of the inner cylinder 102, ensuring a nearly tight fit when the inner cylinder 102 slides within the outer cylinder 101. This design reduces the gap between the outlets of the inner cylinder 102 and the outer cylinder 101, thereby reducing the possibility of the inner cylinder 102 shaking.

[0034] Specifically, two groups of compression grooves 201b are opened on the inner wall of the outer cylinder 101, which are mirror-set with the central axis of the outer cylinder 101. The compression grooves 201b are semi-circular. A plurality of springs 201c are provided on the outer inner wall of the compression grooves 201b. The other end of the spring 201c is fixedly connected to a connecting arc plate 201d. The connecting arc plate 201d is adapted to the compression grooves 201b, and the ring width of the connecting arc plate 201d is half of the compression grooves 201b. This allows the connecting arc plate 201d to be elastically connected to the compression groove 201b through the spring 201c, and a number of limiting teeth 201e are provided on the inner side of the connecting arc plate 201d. The limiting teeth 201e pass through the inner wall of the compression groove 201b and are connected to the through hole 201a, and the number of limiting teeth 201e form a linear array along the inner wall of the through hole 201a, and the inner side of the limiting teeth 201e presents a downward inclined slope.

[0035] Among them, a rigid tooth 202a is provided at the other end of the inner cylinder 102. The rigid tooth 202a is conical in shape, and its upper side is an inclined surface 202b in the shape of an inclined plane, which cooperates with the limiting tooth 201e, and the bottom diameter of the rigid tooth 202a is approximately equal to the diameter of the through hole 201a, which once again enhances the stability of the inner cylinder 102 sliding in the outer cylinder 101, and the lower side of the rigid tooth 202a and the upper side of the limiting tooth 201e are parallel to each other.

[0036] When in use, when in use again, the inner cylinder 102 slides outward, and the inclined surface 202b of the rigid tooth 202a will squeeze the inner inclined surface of the limiting tooth 201e, pushing the connecting arc plate 201d to move outward, and at the same time squeezing the spring 201c, causing the spring 201c to contract and store elastic potential energy until the rigid tooth 202a passes over the limiting tooth 201e that fits with the rigid tooth 202a. Under the push of the spring 201c, the limiting tooth 201e returns to its original position and contacts the bottom of the rigid tooth 202a, which prevents the inner cylinder 102 from sliding into the outer cylinder 101, achieving the effect of unidirectional movement of the inner cylinder 102.

[0037] Example 2

[0038] Reference Figures 5 and 6 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a limiting unit 200 of the limiting mechanism, which solves the problem that when the internal deformation of the monitored object is compressed, the sensor fails when pulled out.

[0039] Furthermore, when the internal deformation of the monitored object is compression, we can reverse the rigid teeth 202a of the inner cylinder 102 and the limiting teeth 201e of the outer cylinder 101, that is, the inclined surface 202b of the rigid teeth 202a faces downward, and the inner inclined surface of the limiting teeth 201e faces upward. When the internal deformation of the monitored object is compressed, the anchor plate 203a will push the inner cylinder 102 to slide toward the bottom of the inner wall of the outer cylinder 101. Similarly, the rigid teeth 202a will squeeze the limiting teeth 201e, and the limiting teeth 201e will move, allowing the rigid teeth 202a to pass through. However, the upper side of the rigid teeth 202a and the lower side of the limiting teeth 201e are horizontally parallel, and are limited, so that the rigid teeth 202a cannot move in the opposite direction. This achieves the effect that the inner cylinder 102 can only move toward the inner side of the outer cylinder 101 and move in one direction.

[0040] Example 3

[0041] Reference Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a deformation monitoring device that addresses the drawbacks in reading and transmitting sensor data for technical monitoring. It includes the limiting mechanism described in the previous embodiment. The sensor is divided into a monitoring end sensor and an observation end sensor. The monitoring end sensor, consisting of an outer cylinder 101 and an inner cylinder 102, is placed on the monitored object, while the observation end sensor is placed at a centralized station. By observing the state of the entangled particles in the observation end sensor, the state of the monitoring end sensor can be indirectly determined.

[0042] Specifically, the inner cylinder 102 is equipped with a measurement unit array, and 100-1000 entanglement storage units 301a are set in the inner cylinder 102. Each unit stores a pair of entangled particles. Each entanglement storage unit 301a corresponds to a power maintenance unit 301b. The power maintenance unit 301b is connected to the entanglement storage unit 301a through a wire 301c to maintain the quantum entangled state of the entangled particles. The power maintenance unit 301b and the entanglement storage unit 301a are arranged axially along the inner cylinder 102 to form a linear array of 100-1000 measurement units. The interval between each measurement unit is fixed at 0.1-1 mm. A battery compartment is provided at one end of the inner cylinder 102 to provide power for the entanglement storage unit 301a.

[0043] The knife switch is arranged at the receiving groove 203b on the inner wall of the through hole 201a. The knife switch is made of ceramic, which has high hardness, strong wear resistance, and is not easy to deform, thereby ensuring the stability and durability of the knife switch. The sharp blade of the knife switch faces downward and can quickly cut off the wire 301c when the inner cylinder 102 moves. The receiving groove 203b is in a "convex" shape, and its interior can allow the measuring component 301 to pass through, thereby ensuring the accuracy of the knife switch cutting. The knife switch cooperates with the array of limiting teeth 201e on the inner wall of the outer cylinder 101 to ensure that the knife switch only works when the inner cylinder 102 moves in a specific direction, thereby ensuring the unidirectionality of the measurement.

[0044] During use, when the monitored object deforms, the monitoring-end sensor moves with the deformation, causing the inner cylinder 102 to slide out of the outer cylinder 101. This movement triggers a switch on the outer cylinder 101, which cuts the wire 301c connecting the power retention unit 301b to the entanglement storage unit 301a, causing the power retention unit 301b to lose power. Once wire 301c is severed, the entangled particles in the corresponding entanglement storage unit 301a lose their power supply, destroying their quantum entanglement state and transforming the particles into a deterministic state. This loss of entanglement can be detected by the observation-end sensor because the state change of entangled particles is instantaneous and not limited by distance. By monitoring the changes in the state of the entangled particles, the observation-end sensor obtains deformation information. The observation station's computer-automated monitoring and processing system records and analyzes these readings to obtain deformation data of the monitored object. As the monitored object continues to deform, more wires 301c are severed, and the observation station obtains more readings until the deformation stops or the sensor reaches its upper range limit, which is determined by the number of built-in measurement units. When the wires 301c of all the measuring units are cut off, the sensor reaches the upper limit of the range. When the sensor reaches the upper limit of the range, a new sensor needs to be replaced to continue monitoring.
