DETAILED DESCRIPTION

[0028] In the related art, the Internet of Things intelligent cable ground nail includes a ground nail body, a top cover and a shell with an opening. When installing, a hole needs to be opened on the ground, and the shell is poured into the hole through concrete, then the ground nail body is fixed in the shell, and the top cover is covered at the opening of the shell, and finally the shell and the top cover are fixed through a plurality of bolts. However, when the ground nail body needs to be overhauled or replaced, the worker must sequentially disassemble the plurality of bolts to remove the top cover from the shell, and after the overhaul or replacement of the ground nail body is completed, the worker must tighten the plurality of bolts again to fix the top cover on the shell, which leads to a cumbersome and low-efficiency process of overhauling or replacing the ground nail body. Therefore, the present application proposes an Internet of Things intelligent cable ground nail in the following embodiments, which has a more convenient process of overhauling or replacing the ground nail body, thereby avoiding the above-mentioned drawbacks in the related art.

[0029] In order to make the purpose, technical scheme and advantages of the present application more obvious and easy to understand, the present application will be described clearly and completely below in combination with the embodiments of the present application and the corresponding drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. It should be understood that the following described embodiments of the present application are only used to explain the present application and do not limit the present application, i.e. all other embodiments obtained by those skilled in the art without creative labor based on the various embodiments of the present application belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a top view of the first cable ground nail, Figure 2 is a structural schematic view of the shell, Figure 3is a sectional view of the limiting assembly in the first cable ground nail. The embodiment provides an Internet of Things intelligent cable ground nail, which comprises a ground nail body 300, a top cover 200, a limiting assembly 400, and a hollow shell 100, the shell 100 is arranged in the installation hole opened on the ground where the cable is buried, the shell 100 has a shell opening 110 which is in communication with the inside, the ground nail body 300 is arranged in the shell 100, the limiting assembly 400 comprises a main limiting structure 410 and a from limiting structure 420, the main limiting structure 410 is arranged on the top cover 200 and close to the edge of the top cover 200, and the from limiting structure 420 is arranged on the shell 100 and close to the shell opening 110, and the top cover 200 is arranged on the shell 100 to close the shell opening 110.

[0031] Specifically, when the top cover 200 is arranged on the shell 100, the main limiting structure 410 is used to insert into the from limiting structure 420 so that the top cover 200 is relatively fixed with the shell 100, or is used to withdraw from the from limiting structure 420 to release the relative fixation between the top cover 200 and the shell 100. Based on this, when the ground nail body 300 in the shell 100 needs to be repaired or replaced, the main limiting structure 410 is first withdrawn from the from limiting structure 420 to release the relative fixation between the top cover 200 and the shell 100, then the top cover 200 is opened to separate from the shell 100, and finally the ground nail body 300 in the shell 100 is taken out to repair or replace; after the repair or replacement of the ground nail body 300 is completed, the ground nail body 300 is first placed in the shell 100, then the top cover 200 is arranged on the shell 100 to close the shell opening 110, and finally the main limiting structure 410 is inserted into the from limiting structure 420 so that the top cover 200 is relatively fixed with the shell 100, thereby achieving the repair or replacement of the ground nail body 300.

[0032] In the embodiment, the depth of the installation hole can be greater than the height of the shell 100, or can be less than the height of the shell 100, the shell opening 110 of the shell 100 can be higher than the hole opening of the installation hole, or can be lower than the hole opening of the installation hole, and the specific design can be made according to the actual needs, which is not uniquely limited in the application. However, in order to avoid the influence of the Internet of Things intelligent cable ground nail installed on the ground on the movement of people, cars, bicycles, electric vehicles, motorcycles, etc., preferably, the depth of the installation hole is adapted to the height of the shell 100, the shell opening 110 of the shell 100 is aligned with the hole opening of the installation hole, and when the top cover 200 is arranged on the shell 100, the top wall of the top cover 200 is flush with the ground. In this case, the Internet of Things intelligent cable ground nail installed on the ground can be regarded as a part of the ground, which neither forms a pit on the ground nor forms a protrusion on the ground, thereby avoiding the influence on the movement of people, cars, bicycles, electric vehicles, motorcycles, etc., and at the same time meeting the aesthetic requirements of the ground.

[0033] In the embodiment, the shell 100 is hollow, i.e. the shell 100 has a cavity for accommodating the ground nail body 300, the cavity can be straight or stepped, the cross-sectional shape of the cavity can be any shape common in the art, such as circular, rectangular, polygonal, etc., which can be designed according to actual needs, and the application does not make a unique limitation. However, in order to make the connection between the shell 100 and the top cover 200 more stable and improve the sealing effect of the shell 100, it is preferred that the cavity of the shell 100 is stepped, i.e. the inner wall of the shell 100 includes an inner bottom wall and an inner side wall connected thereto, the inner side wall includes a first inner side wall extending downward from the edge of the shell opening 110, a second inner side wall extending from the first inner side wall to the axis of the shell 100, and a third inner side wall extending downward from the second inner side wall to the inner bottom wall, and the height of the first inner side wall is adapted to the thickness of the top cover 200. Among them, the inner bottom wall is used to bear the ground nail body 300; the second inner side wall is used to contact the bottom wall of the top cover 200 when the top cover 200 is covered on the shell 100, so as to bear the top cover 200; the first inner side wall is used to contact the side wall of the top cover 200 when the top cover 200 is covered on the shell 100, so as to reduce the gap between the side wall of the top cover 200.

[0034] It can be understood that after the top cover 200 is covered on the shell 100, the second inner side wall of the shell 100 will contact the bottom wall of the top cover 200, at this time the top cover 200 and the third inner side wall and the inner bottom wall of the shell 100 will be enclosed to form a containing cavity in the shell 100, which is used to place the ground nail body 300, and after the second inner side wall of the shell 100 contacts the bottom wall of the top cover 200, the sealing of the containing cavity can be enhanced, and at the same time the top cover 200 is carried by the second inner side wall of the shell 100, so that the connection between the shell 100 and the top cover 200 is more stable. Further, after the top cover 200 is covered on the shell 100, the first inner side wall of the shell 100 will contact the side wall of the top cover 200, which means that there is almost no large gap between the first inner side wall of the shell 100 and the side wall of the top cover 200, which can enhance the sealing of the containing cavity on the one hand, and can avoid the accumulation of soil, sand, leaves and other sundries between the first inner side wall of the shell 100 and the side wall of the top cover 200, thereby affecting the normal use of the Internet of Things smart cable ground nail and reducing the aesthetics of the Internet of Things smart cable ground nail.

[0035] In addition, the outer wall of the shell 100 includes an outer top wall extending from the edge of the shell opening 110 in a direction away from the axis of the shell 100 and connected with the first inner side wall. Since the height of the first inner side wall of the shell 100 is adapted to the thickness of the top cover 200, when the top cover 200 is covered on the shell 100, the top wall of the top cover 200 will be aligned with the outer top wall of the shell 100 and the two will be connected with each other. At this time, the top wall of the top cover 200 and the outer top wall of the shell 100 jointly constitute a flat surface flush with the ground, which can not only avoid the influence of the Internet of Things smart cable ground nail on the movement of people, bicycles, electric vehicles, motorcycles, cars, etc., but also meet the aesthetic needs of the ground.

[0036] In the present embodiment, the ground nail body 300 is the core part that plays the main function of the Internet of Things smart cable ground nail, and generally includes a detection and sensing module, a communication module, a control and processing module, a power module, and a warning module, etc. Among them, the detection and sensing module includes various types of sensors such as inclination sensors, displacement sensors, temperature and humidity sensors, etc., which are used to detect various state parameters of the cable ground nail and surrounding environmental information. The communication module includes a wireless communication module (such as a 4G / 5G module, a LoRa module, an NB-IoT module, etc.) or a wired communication module (such as an Ethernet module, etc.), which is used to realize the interconnection and intercommunication between the cable ground nail and the external system, such as transmitting the detected information to the remote management platform or receiving the instructions from the remote management platform, so as to carry out real-time monitoring and management of the cable ground nail. The control and processing module is composed of a microcontroller (MCU) or an embedded system, which has a certain computing and processing capability, and is used to: process and analyze the data collected by the sensor to determine whether the state of the cable ground nail is normal; according to the preset logic and algorithm, decide whether to trigger an alarm or perform other operations; manage the communication module to control the transmission and reception of data. The power module includes a battery, a power management circuit, etc., which is used to power each module in the ground nail body 300 and ensure that the cable ground nail can run stably in different working environments. The warning module includes warning lights, speakers, etc., which are used to warn through light and sound, etc., to remind people of the existence of underground cables. It should be noted that whether the ground nail body 300 includes which types of modules is determined according to actual needs, and the present application does not make a unique limitation on this.

[0037] As can be seen, when the ground spike body 300 in the shell 100 needs to be overhauled or replaced, the main limiting structure 410 is only needed to be withdrawn from the limiting structure 420, and the top cover 200 is only needed to be opened and separated from the shell 100, so that the ground spike body 300 in the shell 100 can be taken out for overhaul or replacement. After the overhaul or replacement of the ground spike body 300 is completed, the top cover 200 is only needed to be covered on the shell 100, and the main limiting structure 410 is only needed to be inserted into the limiting structure 420, so that the relative fixation between the top cover 200 and the shell 100 can be realized. The entire process of overhauling or replacing the ground spike body 300 does not need to sequentially disassemble or tighten a plurality of bolts as in the traditional scheme, is more convenient, and is also more efficient.

[0038] In some embodiments, please refer to Figure 4 , Figure 4 is Figure 3 A local enlarged view of A in FIG. 10, the top wall of the top cover 200 is provided with an annular groove 210 around the axis thereof, the annular groove 210 is adjacent to the edge of the top wall of the top cover 200, the groove wall of the annular groove 210 comprises a groove bottom wall, a first groove side wall close to the edge of the top wall of the top cover 200, and a second groove side wall close to the axis of the top cover 200, the limiting assembly 400 comprises two, the two main limiting structures 410 are both arranged on the groove bottom wall and are symmetrical relative to the axis of the top cover 200, and the two limiting structures 420 are both arranged on the first inner side wall of the shell 100 and are symmetrical relative to the axis of the shell 100. It can be understood that if the main limiting structure 410 is directly arranged on the top wall of the top cover 200, the main limiting structure 410 will be higher than the ground, and the top wall of the top cover 200 and the outer top wall of the shell 100 will no longer form a flat surface, which will inevitably affect the movement of people, cars, bicycles, electric vehicles, motorcycles, etc. Therefore, the annular groove 210 is opened on the top wall of the top cover 200 in the present application, and the main limiting structure 410 is accommodated in the annular groove 210, so as to achieve the purpose of not damaging the flat surface formed by the top wall of the top cover 200 and the outer top wall of the shell 100. Of course, in other embodiments, a groove corresponding to the position of the main limiting structure 410 can also be opened on the top wall of the top cover 200, and the size of the groove is adapted to the main limiting structure 410, so as to accommodate the main limiting structure 410. This also achieves the above purpose, but considering that the space of such a groove corresponding to the main limiting structure 410 is relatively small, and it is difficult to clean the accumulated dirt, sand, leaves and other sundries inside, therefore, the top wall of the top cover 200 is preferably provided with the annular groove 210 with a larger space.

[0039] Specifically, the first slot sidewall of the annular slot 210 is formed with two through holes 211 recessed away from the second slot sidewall and penetrating the top cover 200, the two through holes 211 respectively correspond to the two main limiting structures 410, the limiting hole 421 is opened on the first inner sidewall of the shell 100 from the limiting structure 420, and each through hole 211 is used for: when the top cover 200 is covered on the shell 100, aligning and connecting with the limiting hole 421, so that the limiting hole 421 is in communication with the annular slot 210, to realize the plug-fit of the main limiting structure 410 and the limiting hole 421. It can be understood that, since the main limiting structure 410 needs to be plug-fit with the limiting hole 421, and the through hole 211 is needed to communicate between the main limiting structure 410 and the limiting hole 421, the number of the main limiting structure 410, the limiting hole 421 and the through hole 211 is equal, that is, one main limiting structure 410 corresponds to one through hole 211 and one limiting hole 421, and for the combination of the main limiting structure 410, the limiting hole 421 and the through hole 211, it is not limited to two groups, and in other embodiments, it can also be three groups or more, which can be set according to actual needs, and the application does not make a unique limitation.

[0040] Further, two outer linear grooves 500 are opened on the outer top wall of the shell 100, the two outer linear grooves 500 are respectively arranged corresponding to the two limiting holes 421, two inner linear grooves 600 are opened on the top wall of the top cover 200, the two inner linear grooves 600 are located on the side of the annular slot 210 away from the axis of the top cover 200 and are respectively arranged corresponding to the two through holes 211, the extension direction of the outer linear groove 500 is the same as the axis direction of the limiting hole 421, the extension direction of the inner linear groove 600 is the same as the axis direction of the through hole 211, one end of the outer linear groove 500 is connected to the edge of the outer top wall of the shell 100 close to the shell opening 110, and one end of the inner linear groove 600 is connected to the edge of the top wall of the top cover 200; wherein the inner linear groove 600 is used for aligning and connecting with the outer linear groove 500 after the top cover 200 is covered on the shell 100, to indicate that the through hole 211 is aligned with the limiting hole 421 and the two are connected. That is, after the top cover 200 is covered on the shell 100, although it is not possible to see with the naked eye whether the through hole 211 is aligned and connected with the limiting hole 421, the inner linear groove 600 on the top cover 200 can be aligned and connected with the outer linear groove 500 on the shell 100 by rotating the top cover 200, and since the position of the inner linear groove 600 on the top cover 200 corresponds to the through hole 211 and the position of the outer linear groove 500 on the shell 100 corresponds to the limiting hole 421, when the inner linear groove 600 is aligned and connected with the outer linear groove 500, it can be considered that the through hole 211 is aligned and connected with the limiting hole 421, and then the main limiting structure 410 can be inserted into the limiting hole 421 through the through hole 211, so that the shell 100 and the top cover 200 are relatively fixed.

[0041] In some embodiments, still referring toFigure 4 The main limiting structure 410 includes a plug rod 411 and a sliding structure 412 arranged on the groove bottom wall.

Specifically, when the top cover 200 is arranged on the shell 100, the plug rod 411 is used to slide away from the second groove side wall relative to the groove bottom wall through the sliding structure 412 to extend out of the through hole 211 and be inserted into the limiting hole 421, so that the top cover 200 is relatively fixed with the shell 100, or slide towards the second groove side wall relative to the groove bottom wall through the sliding structure 412 to withdraw itself from the limiting hole 421 and retract into the through hole 211, so as to release the relative fixation of the top cover 200 and the shell 100.

[0042] As one of the embodiments, the sliding structure 412 includes a sliding rod 4121 and two guide rods 4122. The two guide rods 4122 are oppositely and spacedly arranged on the groove bottom wall. The opposite two ends of each guide rod 4122 respectively abut against the first groove side wall and the second groove side wall. Each guide rod 4122 is provided with a sliding groove 4123 extending along the axis direction of the guide rod 4122 on the side close to the other guide rod 4122.
