Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of devices for assisting measurement, detection or judging object state change, especially a kind of detection displacement state change covering device. BACKGROUND

[0002] Modern electronic technology evolves rapidly, and common state changes or detections can be matched with electronic sensors in various occasions to quickly determine and confirm the changes of object state, and can be widely applied to temperature, humidity, hardness or displacement state changes that cannot be directly judged visually.

[0003] However, in some specific application scenarios, electronic sensors are usually equipped with traditional mechanical structure to detect state changes due to their lack of power supply or high temperature, high pressure or inability to install electronic sensors.

[0004] In places without power supply or where it is difficult to provide power supply, only mechanical or purely mechanical methods can be used to detect specific states. For example, whether the base positioning bolt in a high-voltage tower, the track positioning bolt of a high-speed railway, the screw bolt of a high mountain or a cross-sea bridge has fallen off, etc. Since it is difficult to lay power facilities in these places, the number of bolts to be detected is large, and subsequent construction is also difficult, it is not easy to implement the power network or electronic transmission of electronic sensors. Therefore, in order to overcome such problems, the inventor has researched the utility model technology to solve the problem of detecting specific places, such as how to detect bolt loosening or displacement state change in difficult construction areas. UTILITY MODEL CONTENTS

[0005] As described above, since it is difficult to use or install electronic sensors for displacement detection in specific scenarios, the present utility model was developed to improve the existing deficiencies based on the inventor's research and testing.

[0006] The main purpose of the utility model is to provide a kind of covering device for detecting displacement state change, which is used to cover and fix a measured object. The covering device includes a covering object, which is waterproof and can tightly cover the measured object. The shape of the covering object matches the measured object, and a deformation zone is provided on the covering object. A detection member is connected to the covering object and corresponds to the deformation zone of the covering object. When the covering object is deformed by external force, the deformation zone will change, affecting the detection member and causing the detection member to lose all or part of its detection function.

[0007] Preferably, the displacement state change detecting covering device, wherein the outer surface of the covering is provided with a ring-shaped deformation zone, and the detecting member is arranged in the deformation zone.

[0010] Preferably, the displacement state change detecting covering device, wherein the object to be detected is a spring washer, and the covering covers the outside of the object to be detected.

[0011] Preferably, the displacement state change detecting covering device, wherein the detecting member is an RFID electronic tag.

[0012] Preferably, the displacement state change detecting covering device, wherein the detecting member is a compression spring, and the detecting member is arranged between the covering and the object to be detected.

[0013] Preferably, the displacement state change detecting covering device, wherein the outer surface of the covering is provided with a ring-shaped deformation zone.

[0014] By means of the above technical features, the displacement state change detecting covering device can be applied to the scenes such as high mountain electric towers, sea-crossing bridges, high mountain bridges and high-speed railways which cannot or are not easy to lay power devices, and only needs to be installed on the object to be detected at a proper place, so as to easily identify whether the displacement state of the object to be detected has changed or the changed state has affected the safety level through visual observation or remote detection through a wireless network, thereby accelerating subsequent maintenance and repair, effectively reducing the workload of one-by-one confirmation, not relying on power supply in installation, and being simple in structure, extremely low in production cost, capable of completing complex engineering detection and confirmation through the simplest work flow, and greatly improving the maintenance efficiency of engineering.

[0029] This utility model is a covering device for detecting displacement state changes. It is used to cover and fix an object to be tested. It includes a covering and a detection element. The covering is made of soft material, waterproof and can tightly cover the object to be tested. A deformation zone is provided on the surface of the covering. The detection element is connected to the covering.

[0030] like Figure 1 As shown, this is the first embodiment of the present invention. The covering device 10A for detecting displacement changes is used to cover and fix a test object S. The covering device 10A includes a covering material 11 and a detection element 12. The covering material 11 is made of a soft / hard material, is waterproof, and can tightly cover the test object S. In this embodiment, the covering material 11 can be one or a combination of plastic, rubber, or silicone. The covering material 11 is mainly used to cover the test object S. The shape of the covering material 11 is determined by the shape of the object S to be tested. For example, in the illustration of this utility model, the object S to be tested is a bolt assembly, including a bolt S1 and a spring washer S2. When the bolt S1 is locked, it can compress the spring washer S2 into a flat state. Therefore, the shape of the covering material 11 is to match and be able to partially or completely cover the periphery of the object S to be tested. In this embodiment, the covering material 11 is a rectangular soft sleeve with a U-shaped cross-section.

[0031] like Figure 1As shown, an annular deformation area 110 is provided on the outer surface of the covering 11. The cross-sectional thickness of the deformation area 110 is smaller than that of other parts, and a recessed annular groove is formed around the covering 11 for placing the detection element 12. The detection element 12 is connected to the covering 11. In this embodiment, the detection element 12 is a soft electronic tag of RFID, which has a small circuit and is not flexible or elastic. It can passively receive the transmission of wireless electronic signals and interact with the signal of the receiving end. The detection element 12 is disposed in the deformation area 110 of the covering 11.

[0032] like Figure 2 As shown, the first embodiment of this utility model, when in use, is mainly for measuring whether the bolts used for fixing in various areas such as high-altitude power towers, cross-sea bridges, high-altitude bridges, and high-speed railways are loose in places where it is impossible to lay power lines or where it is not easy to transmit signals by electricity. That is, the object to be tested S in the first embodiment of this utility model.

[0033] The test object S is set as a bolt assembly, including a bolt S1 and a spring washer S2. When the bolt S1 is locked, it can compress the spring washer S2 into a flat state. In the initial state of the test object S (i.e., the displacement change is zero), the covering device 10A for detecting displacement changes is covered on the outer periphery of the test object S, and the covering device 10A can be effectively bonded to the contact surface of the spring washer S2 by means of bonding and curing adhesive.

[0034] In this state, since the covering device 10A is in normal condition, even if the remote operation signal is transmitted to the detector 12, it can receive a normal transmission signal. By testing the state of the detector 12 through a remote electronic device, the need to repeatedly perform tests or confirmations can be reduced.

[0035] Suppose that when bolt S1 loosens and shifts, the tension of spring washer S2 and bolt S1 will change, causing spring washer S2 to return to its original shape and push upward. This will cause the entire covering 11 to be stretched. Since the shape changes along the axial direction of the covering 11, the deformation zone 110 may be stretched significantly. The external force may cause the deformation zone 110 to deform axially or break. At this time, the non-flexible and non-elastic detection element 12 will also be stretched by the external force, resulting in breakage or deformation, thereby damaging the normal operation function of the detection element 12, causing the detection element 12 to malfunction and unable to continue receiving and transmitting electronic signals.

[0036] In this way, the test object S sent to a specific area via external electronic facilities will no longer be able to send back normal signals, or the detection device 12 will lack the information to send back signals. This will allow us to determine that the test object S may have displacement or deformation, and thus quickly determine the subsequent maintenance or repair.

[0037] The same approach can also be applied to situations such as the aforementioned high-altitude power towers, cross-sea / high-altitude bridges, and high-speed railways. In addition, it can be combined with drones or set up signal transmitting devices on high-speed trains. If a signal cannot be received where it should be transmitted, it can immediately determine the possibility of displacement or deformation, which helps to investigate and prevent the possibility of public hazards.

[0038] A second embodiment of this utility model is, for example... Figure 3 , 4 The covering device 10B for detecting displacement changes shown has a structure that is largely the same as that of the first embodiment. It also includes a covering 11 and a detection element 12. The covering device 10B is also applied to and covers the outer periphery of the object to be tested S. The shape of the covering 11 also matches the whole or most of the object to be tested S. The difference is that the covering 11 can have a deformation zone 110 set on the radial connection line from the radial position of the outer peripheral surface to the radial line of the cylindrical surface. The deformation zone 110 can be a fragile area formed by many fine holes, kerfs, and grooves. Such a structure will deform and be destroyed when subjected to force. The aforementioned deformation zone 110 structure can also be applied to other embodiments of this utility model. When the covering 11 is subjected to a sufficiently large external force, it will break or crack first at the position of the deformation zone 110.

[0039] The detection element 12 is also a soft electronic tag of RFID. It can be directly wrapped inside the cover 11 by integral injection molding, or it can be additionally pasted on the inside or outside of the cover 11. As long as the detection element 12 can be bonded to the cover 11, the bonding method is not limited in this embodiment.

[0040] The second embodiment of this utility model is used in the same way as the first embodiment. When the covering device 10B is placed on the outside of the object to be tested S and is fixed by using a curing adhesive, if either the bolt S1 or the spring washer S2 of the object to be tested S is displaced, it will deform along the axial direction of the covering 11. Since the deformation area 110 of the covering 11 is set to apply force along the axial direction, the covering 11 will break along the direction of the deformation area 110, thereby breaking the detection element 12 and causing the detection element 12 to malfunction. Other parts are roughly the same as the first embodiment and will not be described in detail here.

[0041] The third embodiment of this utility model is as follows: Figure 5 ,6 The covering device 10C for detecting displacement state changes can be set as needed. For example, if the object to be tested S only includes a spring washer S2, the size of the covering part 11 only needs to match the spring washer S2. That is, the size of the covering part 11 only needs to cover the outer periphery of the spring washer S2 of the object to be tested S. Other parts are roughly the same as the first and second embodiments described above.

[0042] The usage of the third embodiment is as follows: Figure 6 As shown, when the bolt S1 of the object under test S loosens, it mainly affects the displacement of the spring washer S2, which in turn pulls on the covering 11, causing the detection element 12 installed inside to break or be damaged, resulting in the inability to detect. Other parts are the same as the usage in the previous embodiment, and will not be described in detail here.

[0043] The fourth embodiment of this utility model is as follows: Figure 7 As shown, the covering device 10D for detecting displacement state changes is also disposed on the outer periphery of the object to be tested S. The object to be tested S may be only a bolt S, or a combination including a bolt S1 and a spring washer S2, or as in the previous embodiment, only a spring washer S2, which is also within the scope of this utility model.

[0044] Preferably, in this embodiment, the object to be tested S includes a combination of bolt S1 and spring washer S2, the covering 11 is a sleeve that can cover the object to be tested S, and a deformable area 110 in a circumferential recess is provided on the outside of the covering 11. The detection element 12 in this embodiment is a compression spring and is disposed between the covering 11 and the object to be tested S.

[0045] The fourth embodiment of this utility model is used as follows: the covering device 10D is placed on the outside of the object to be tested S, and the covering device 10D is fixed to the periphery of the object to be tested S with curing adhesive. The detection element 12 is pressed against the top of the object to be tested S. When the spring washer S2 of the object to be tested S changes displacement, it will apply upward pressure to the detection element 12. When this pressure is greater than the deformation of the covering element 11, the covering element 11 will undergo physical deformation and cracks will start to form from the deformation area 110, causing it to crack. Finally, the detection element 12 will pop open the top of the covering element 11, causing the shape of the covering element 11 to change significantly, so that the user can directly see the object to be tested inside, thereby achieving the effect of quickly identifying displacement changes.

[0046] This utility model only proposes a simple structure to achieve the aforementioned complex application. The scope of this utility model includes, but is not limited to, the detection of bolt deformation. As long as there is a solid phase connection and it is difficult to measure its displacement change, and the displacement change can produce a large displacement, this utility model is possible. This utility model only proposes one solution, but specific application scenarios also include, for example, the detection of deformation of heavy hooks, the detection of deformation of bridges, dams, nuclear power plants or national key facilities that are sensitive to displacement, which are all possible application scenarios and directions of this utility model.

[0047] This invention relates to a covering device for detecting changes in displacement, which can have the following applications.

[0048] 1. In scenarios such as high-altitude power towers, cross-sea bridges, high-altitude bridges, and high-speed railways where it is impossible or difficult to lay power installations, the device of this utility model can be installed on the object under test at an appropriate location. This allows for easy identification of whether the displacement state of the object under test has changed or whether the changed state has affected the safety level, thereby accelerating subsequent maintenance and upkeep.

[0049] 2. The covering device of this utility model can effectively reduce the workload of one-by-one confirmation, and the installation does not rely on power supply. Moreover, it has a simple structure and extremely low production cost. It can complete the detection and confirmation of complex projects through the simplest workflow, greatly improving the maintenance efficiency of engineering projects.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model's technical solution. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the content of the present utility model's technical solution shall still fall within the scope of the present utility model's technical solution.
