With the increasing exploration and development needs of the Changqing exploration area, the exploration scope is gradually covering complex urban environments such as counties and cities. Urban surfaces are mostly hard surfaces paved with cement and asphalt, making it difficult for node equipment to couple with them. At the same time, urban areas have high population density and high mobility, leading to frequent node equipment loss. How to achieve good coupling between eSeis node equipment and hard surfaces, ensuring effective reception while preventing data loss, and guaranteeing equipment security and the preservation of acquired data, presents a significant challenge for the implementation of eSeis node equipment in complex environments such as urban areas. Utility Model Content

[0003] To address the aforementioned issues, this invention provides an anti-theft device for node devices coupled to hard surfaces, thereby at least resolving the problem that eSeis node devices currently cannot achieve good stability and coupling with hard surfaces in complex environments.

[0004] To address one of the problems, this utility model provides an anti-theft device for node equipment coupled with a rigid surface. The technical solution is as follows:

[0005] An anti-theft device for node devices with rigid surface coupling, the device comprising:

[0006] A motherboard is connected, with a first side for fixing to a hard surface, and a coupling interface provided on a second side of the motherboard opposite to the first side.

[0007] The node device is fixed to the connection motherboard via the coupling interface;

[0008] The first side of the connecting motherboard matches the shape of the hard surface to achieve fixation and coupling between the node device and the hard surface.

[0009] To further address the issue of eSeis node devices being easily lost in complex environments, as a preferred solution, the connection motherboard is also equipped with an anti-theft interface, through which the node device is connected to the connection motherboard.

[0010] As one of the preferred options, the device also includes:

[0013] As one preferred embodiment, the connecting motherboard is provided with multiple fixing holes, which penetrate through the first and second sides of the connecting motherboard; the device further includes:

[0014] Multiple fasteners, each of which passes through each of the fixing holes and is connected to the hard surface.

[0015] As one of the preferred solutions, each of the fasteners is a pneumatic nail, and the plurality of fastening holes are evenly spaced along the circumferential distance of the connecting motherboard.

[0016] As one of the preferred options, the anti-theft interface is located on the second side of the motherboard.

[0017] As one of the preferred options, the anti-theft interface is a nut, which is welded to the connecting motherboard.

[0020] As one of the preferred embodiments, the projection of the node device on the second side of the square steel plate is located within the square steel plate, and the anti-theft interface and fixing hole are both set in the area of ​​the square steel plate that is offset from the projection.

[0021] Compared with the prior art, this application has the following advantages:

[0022] This application provides an anti-theft device for node devices coupled to a hard surface. The device includes: a connecting motherboard, a first side of which is fixed to the hard surface, and a coupling interface on a second side of the connecting motherboard opposite to the first side; and a node device fixed to the connecting motherboard through the coupling interface. The first side of the connecting motherboard matches the shape of the hard surface to achieve fixation and coupling between the node device and the hard surface.

[0023] Compared to existing methods that require extensive construction work to achieve stability, the system provided in this application uses a connecting motherboard to fix the node device to a hard surface. This enables stable and effective coupling between the eSeis node device and any hard surface, ensuring the stability and accuracy of the node device in various environments. The seamless and tight contact between the connecting motherboard and the hard surface is analogous to the tight coupling between the node instrument's tail and the ground. This method of fixing the node device to a hard surface is simpler and provides better stability and coupling. The overall design of the device is simple, easy to install and maintain, and can greatly improve work efficiency. Attached Figure Description

[0031] 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 only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] It should be noted that there are typically two methods for installing the node device 2 onto hard surfaces. One method involves filling bags with soil and inserting the geophone into the soil-filled bags. This method results in poor coupling between the node device 2 and the hard surface and lacks anti-theft functionality. The other method involves drilling holes in the hard surface with an electric drill and inserting the geophone's tail cone into the holes. While this method provides better coupling between the node device 2 and the hard surface, it requires excavating the ground and driving piles, making construction difficult, time-consuming, and labor-intensive, and similarly lacks anti-theft functionality.

[0033] In actual use, complex environments such as urban areas experience severe interference. If the eSeis node device 2 is not properly coupled with the hard surface, it will negatively impact the quality of seismic data. Depending on the observation system, production efficiency, and production organization model, node device 2 typically needs to be left unattended for 6-8 days, or even longer, before it can be retrieved. During this period, it is highly susceptible to theft. If this occurs, all received data in that channel will be lost, resulting in serious consequences such as data loss, incomplete data, and poor final image quality.

[0034] The successful development of eSeis node device 2 marks a major leap forward in the field of geophysical exploration equipment. It has powerfully promoted the in-depth deployment of seismic exploration in traditionally "difficult" areas such as complex urban areas, and ushered in a new era of seismic exploration.

[0035] In view of this, we urgently need a new type of device that is specifically designed based on the structure of the eSeis node device 2. On the one hand, it should ensure that the eSeis node device 2 is stably and effectively coupled to the hard ground surface to ensure data quality; on the other hand, it should play a role in preventing loss, effectively resisting potential security risks in complex environments, and ensuring equipment safety.

[0036] The main purpose of this utility model is to solve the problem of fixing and coupling the eSeis node device 2 with the hard surface, referring to... Figure 1 and Figure 2 , Figure 1 This is a structural diagram illustrating the overall structure of the anti-theft device for node equipment coupled to a rigid surface, as shown in this utility model. Figure 2 This is a perspective structural diagram of the connecting motherboard shown in this utility model. This utility model provides an anti-theft device for a node device 2 coupled to a hard surface. The device includes: a connecting motherboard 1, a first side of which is fixed to the hard surface, and a coupling interface 12 provided on a second side of the connecting motherboard 1 opposite to the first side; and a node device 2, which is fixed to the connecting motherboard 1 via the coupling interface 12. The first side of the connecting motherboard 1 matches the shape of the hard surface to achieve fixation and coupling between the node device 2 and the hard surface.

[0037] In this embodiment, the node device 2 is an eSeis node device 2, which is mainly used in urban environments. Urban ground is usually a hard surface such as cement, asphalt, and tiles. Therefore, a connecting motherboard 1 is designed to fix the node device 2 on the hard surface and has a good coupling effect with the hard surface.

[0038] Specifically, such as Figure 1 As shown, the first side is defined as the bottom surface. The bottom surface of the connecting motherboard 1 is fixed to a hard surface. A coupling interface 12 is provided on the top surface of the connecting motherboard 1. This coupling interface 12 is used to connect the node device 2. The node device 2 is fixed to the connecting motherboard 1 through the coupling interface 12, so that the node device 2 and the connecting motherboard 1 are tightly integrated to form an integral device. The coupling interface 12 can be designed with a structure that matches the connection interface of the node device 2, realizing the integrated connection between the node device 2 and the connecting motherboard 1. The connecting motherboard 1 is made of high-strength metal or alloy materials, improving its robustness and durability for long-term use.

[0039] The bottom surface of the connecting motherboard 1 can be fixed to a hard surface using methods such as bolts, pneumatic nails, adhesive, glue, brackets, or magnetic attraction. Therefore, by using the connecting motherboard 1, the node device 2 can be fixedly connected to any hard surface, ensuring the stability of the node device 2 after installation. Compared to existing fixing methods (either using sandbags or pre-drilling holes in the ground), which have limited applicability, the node device 2 of this embodiment is suitable for assembly on various hard surfaces, including ground and rock surfaces, and its applicability is very wide.

[0040] Specifically, the method of fixing the motherboard 1 to the rigid surface offers multiple flexible options. For example, methods such as pneumatic nail fixing, bracket fixing, adhesive fixing, or magnetic fixing can be used. Compared to existing fixing methods, it eliminates the need for pre-drilling, drilling, or anchoring into the rigid surface to fix the node device 2. This reduces the workload and cost. The fixing method used in this embodiment does not require extensive construction work such as excavating the ground or driving piles, thus significantly reducing the workload and cost.

[0041] Alternatively, by using pneumatic nails or bolts for fixing, the bottom of the node device 2 is rigidly fixed to the connecting motherboard 1, and the connecting motherboard 1 is rigidly fixed to the hard surface. This allows the node device 2 to be stably and securely fixed on the hard surface, preventing the connecting motherboard 1 and / or the node device 2 from loosening or floating due to external forces, thus achieving good coupling with the hard surface.

[0042] In conjunction with the above embodiments, the mainboard 1 is preferably fixed to a hard surface using pneumatic nails. Compared to existing fixing methods that require extensive construction work to achieve stability, this fixing method is simpler and more stable. It eliminates the need for pre-drilling, burring, or anchoring the hard surface, while ensuring that the node device 2 is stably and securely fixed to the hard surface, thereby ensuring the stability and accuracy of the equipment in various environments.

[0043] Correspondingly, a pneumatic nail fixing method is adopted, with multiple fixing holes 13 provided on the main board 1, the fixing holes 13 penetrating the first and second sides of the main board 1; the device also includes multiple fixing components, each of which passes through each fixing hole 13 and connects to the hard surface. The fixing components are pneumatic nails. In this embodiment, the main board 1 is pre-drilled, and the fixing holes 13 penetrate the upper and lower surfaces of the main board 1. A pneumatic tool (such as a pneumatic nail gun) is used to drive the pneumatic nail through the fixing holes 13 on the main board 1 into the hard surface. A pneumatic nail is a nail driven by compressed air. Using pneumatic nails as fixing components is suitable for fixing hard surfaces such as cement, asphalt, and brick, and has low destructive power to the ground surface, enabling quick and secure fixing of the main board 1 to the hard surface. Therefore, during installation, the device can use a pneumatic nail gun to drive the pneumatic nail, eliminating the need for pre-drilling holes in the hard surface, thus rigidly fixing the main board 1 to the hard surface, greatly improving installation efficiency, allowing for large-scale rapid deployment, and providing strong fixing force, thereby ensuring good coupling between the node device 2 and the hard surface.

[0044] Preferably, the plurality of fixing holes 13 are evenly spaced along the circumference of the connecting motherboard 1. The evenly spaced fixing holes 13 along the circumference of the connecting motherboard 1, and the use of multi-point injection with pneumatic nails, can ensure the stability of the connecting motherboard 1 and the hard surface, thereby improving the overall stability.

[0045] As a further explanation of this embodiment, the bottom surface of the connecting motherboard 1 is fixed to the hard surface. The bottom surface of the connecting motherboard 1 can be designed and adjusted according to the shape of different hard surfaces, giving it strong adaptability and meeting the installation requirements of various hard surfaces, thus expanding the installation range of the node device 2. By matching the shape of the bottom surface with the shape of the hard surface, the connecting motherboard 1 is tightly attached to the ground. Then, the node device 2 is fixed to the connecting motherboard 1, allowing the node device 2 to be placed stably on the hard surface. The node device 2 is stably installed while having a good coupling effect with the hard surface.

[0046] In some embodiments, the bottom surface of the motherboard 1 is designed as a flat surface, suitable for flat cement floors and other surfaces in urban installation environments.

[0047] In some embodiments, the main board 1 is designed as a flat plate, which facilitates integral fabrication and allows it to be tightly fitted and fixed to the urban surface.

[0048] In some embodiments, for special hard surfaces, such as those with uneven shapes like protrusions, depressions, or ribs, the ground surface of the connecting motherboard 1 can be designed to adapt to these shapes, improving stability. Thus, when the node device 2 is fixed to the top surface of the connecting motherboard 1 via the coupling interface 12, the connecting motherboard 1 is stably fixed to the hard surface, enabling the eSeis node device 2 to be securely and well coupled to any hard surface.

[0049] In summary, compared to existing methods that require extensive construction work to achieve stability, this device uses a connecting motherboard 1 to fix the node device 2 to a hard surface. This ensures stable and good coupling between the eSeis node device 2 and any hard surface, thereby guaranteeing the stability and accuracy of the node device 2 in various environments. The connecting motherboard 1 makes seamless and tight contact with the ground through air nails, similar to the tight coupling of the node instrument's tail cone to the ground. Fixing the node device 2 to a hard surface is simpler and provides better stability and coupling. This device has a simple design, is easy to install and maintain, and can greatly improve work efficiency.

[0050] As a further explanation of this embodiment, it is necessary to break the connection between the connecting motherboard 1 and the hard surface or between the node device 2 and the connecting motherboard 1 in order to steal the node device 2. The connecting motherboard 1 and the hard surface are fixed with pneumatic nails, and the node device 2 is fixed to the connecting motherboard 1. The connecting motherboard 1 is not easy to remove from the hard surface, so the fixation with pneumatic nails increases the difficulty of losing the node device 2 to a certain extent.

[0051] Please continue reading. Figure 2 To further address the issue of eSeis node devices 2 being easily lost in complex environments, this embodiment of the invention also adds a connection between the node device 2 and the connecting motherboard 1 to enhance the anti-loss effect. Specifically, the connecting motherboard 1 is also provided with an anti-theft interface 11, through which the node device 2 is connected to the connecting motherboard 1.

[0052] In this embodiment, the node device 2 is fixed to the connecting motherboard 1 through the coupling interface 12, and then connected to the connecting motherboard 1 through the anti-theft interface 11. The node device 2 is locked to the connecting motherboard 1 through the anti-theft interface 11 and can only be removed by unlocking. Therefore, it can prevent unauthorized personnel from disassembling the node device 2 on the connecting motherboard 1 and improve the anti-theft level.

[0053] Preferably, the anti-theft interface 11 is a universal interface with a through hole allowing the steel wire rope 32 to pass through. The steel wire rope 32 is confined within the anti-theft interface 11 by the wall of the through hole, thereby connecting the steel wire rope 32 to the connecting motherboard 1. Specifically, the device further includes a steel wire rope 32 lock, comprising a steel wire rope 32 and a latch 31 connected to each other; wherein the free end of the steel wire rope 32 passes sequentially through the pre-set hole 21 on the housing of the node device 2 and the anti-theft interface 11, and is fastened by the latch 31. In this embodiment, a steel wire rope 32 lock is used to lock and unlock the node device 2 and the connecting motherboard 1. The wire rope 32 itself is flexible, strong and adjustable in length. At the same time, the anti-theft interface 11 has a universal through hole for the wire rope 32 to pass through. Therefore, the wire rope 32 can pass through the housing of different models of node equipment 2 and the anti-theft interface 11 of different shapes and sizes. In addition, the wire rope 32 and the lock 31 are difficult to be damaged, which increases the difficulty for unauthorized personnel to remove the node equipment 2 from the connecting motherboard 1.

[0054] The steel wire rope 32 passes through the anti-theft interface 11 and the node device 2 and is secured by a latch 31, which can be a mechanical lock or a combination lock. Different types of steel wire rope 32 locks are commercially available; they are inexpensive, easy to procure, and quick to install. Therefore, this application uses the steel wire rope 32 and the anti-theft interface 11 to provide a highly efficient, versatile, and cost-effective anti-theft solution for the node device 2, particularly suitable for use in urban environments requiring rapid deployment and retrieval.

[0055] For example, in a common type of wire rope 32 lock, the two ends of the wire rope 32 are two free ends. These two free ends pass through the node device 2 and the anti-theft interface 11 respectively, and are then locked together by a mechanical lock. As another example, in a common type of wire rope 32 lock, one end of the wire rope 32 is a fixed end, fixed to the latch 31, and the other end is...

[0056] The free end passes through the hole 21 and the anti-theft interface 11 on the node device 2 in sequence, and is automatically locked into the lock slot of the latch 31.

[0057] It is worth mentioning that the housing of node device 2 has pre-set holes 21, which are usually reserved for ropes so that operators can carry node device 2 by hand. For example, two holes 21 are set on opposite sides of the housing of node device 2, and the two holes 21 on the same side are connected. Therefore, the design of using a wire rope 32 lock does not require changing the original structure of node device 2. The anti-theft deployment can be completed simply by using the pre-set holes 21 on the housing of node device 2, which is also economical.

[0058] Thus, this device can serve as an anti-theft measure in densely populated areas such as villages, towns, and cities, effectively preventing equipment theft. Compared to existing technologies that cannot prevent equipment theft, this device significantly improves equipment security and reduces economic losses.

[0059] It is known that the steel wire rope 32 has high flexibility, allowing installers to pass it through the anti-theft interface 11 and the hole 21 on the node device 2 from different directions. Therefore, the anti-theft interface 11 can be located on any side of the connecting motherboard 1 except for the bottom surface. As a preferred design, the anti-theft interface 11 is located on the second side of the connecting motherboard 1. The connecting motherboard 1 can be designed to be thinner, with a wider top surface to facilitate the installation of the node device 2. By placing both the anti-theft interface 11 and the coupling interface 12 on the top surface of the connecting motherboard 1, the wider installation area on the top surface facilitates the installation of the anti-theft interface 11 on the connecting motherboard 1. Furthermore, the anti-theft interface 11 does not need to protrude from the side of the connecting motherboard 1, reducing the overall height and volume of the connecting motherboard 1. The thinner connecting motherboard 1 can fit tightly against the ground, making the device more compact and improving its overall aesthetics.

[0060] More preferably, the anti-theft interface 11 is a nut, which is welded to the connecting main board 1. In this embodiment, a nut is used as the anti-theft interface 11. As a common standard part, the nut is inexpensive and easy to procure, which can significantly reduce the manufacturing cost of this device. The nut has high strength and can be welded to the connecting main board 1 as a whole, providing high structural strength and making it difficult to be damaged by external impact or human intervention, thus ensuring the long-term stability of the anti-theft interface 11.

[0061] Among them, because the nut has wide versatility, the model of the nut can be selected according to actual needs to be suitable for wire ropes of different diameters 32, which enhances the flexibility of the system.

[0062] Therefore, using a nut welded to the motherboard 1 as the anti-theft interface 11 has many advantages, such as low cost, high reliability, ease of use, good anti-theft performance, and strong compatibility.

[0063] In some embodiments, the coupling interface 12 is located in the central region connecting to the motherboard 1, and the anti-theft interface 11 can be located on any side of the surrounding region connecting to the motherboard 1. The coupling interface 12 in the central region and the anti-theft interface 11 in the surrounding region can be directly opposite each other or staggered. Depending on the ease of operation, the operator can pass the steel wire rope 32 through the anti-theft interface 11 from any direction.

[0064] In some embodiments, the nut can be arranged longitudinally, with the through hole on the nut through which the wire rope 32 passes facing the coupling interface 12. In some embodiments, the nut can be arranged laterally, with the through hole on the nut through which the wire rope 32 passes facing the corner of the connecting main board 1. In some embodiments, the nut can be arranged at an angle, with the through hole on the nut through which the wire rope 32 passes facing any direction.

[0065] As a further explanation of this embodiment, the coupling interface 12 is a bolt with an external thread on its outer circumference. This external thread matches the internal thread of a pre-set threaded groove on the housing of the node device 2. In this embodiment, the node device 2 has its own threaded groove, and the tail cone is designed with a threaded portion, which mates with the threaded groove on the bottom of the node housing to connect the two together. During field exploration, the node device 2 is equipped with a tail cone, which is inserted into the ground surface to prevent the node device 2 from moving or tilting, maintaining its stability. Therefore, after removing the tail cone, a threaded groove will remain on the bottom of the housing of the node device 2. In this embodiment, for environments with relatively flat and hard surfaces such as urban ground, the threaded groove on the node device 2 can be used to mate with the threaded bolt on the connecting motherboard 1, thereby connecting the node device 2 and the connecting motherboard 1 together.

[0066] The housing of node device 2 is inserted into the screw on the connecting main board 1. The bolted connection has high strength and high reliability, and the external thread of the bolt tightly engages with the internal thread of the threaded groove on the housing of node device 2. The connecting main board 1 is stably installed on the ground, thus acting as the tailbone of node device 2, ensuring the stability of node device 2 in complex environments, while also ensuring the coupling efficiency between the detector inside node device 2 and the ground, so that the seismic wave signal can be effectively transmitted to the detector.

[0067] The screw can be connected with a through-threaded bolt. The screw can be welded or embedded into the main board. The screw is also a standard component, high in strength, inexpensive, and readily available, resulting in low manufacturing costs for the entire device and making it suitable for large-scale deployment of node equipment 2.

[0068] Furthermore, the connecting motherboard 1 is a square steel plate. Since the node device 2 is square in shape, the connecting motherboard 1 is also designed to be square and made of alloy steel, which provides high rigidity and enhances the overall structural stability. The square steel plate is thin, with flat surfaces on both the top and bottom, which helps ensure a tight fit between the node device 2 and the connecting motherboard 1, as well as between the connecting motherboard 1 and the hard surface, ensuring the stability of the node device 2 installation while improving the coupling effect.

[0069] The square steel plate has regular edges, and four fixing holes 13 can be evenly set at the four corners or four sides. Pneumatic nails are driven into the fixing holes 13, and a coupling interface 12 is set in the center of the square steel plate. An anti-theft interface 11 is set in the inner area of ​​any side. The square steel plate has a mature and low-cost processing technology, a simple structure, and further reduces production costs.

[0070] Furthermore, the projection of node device 2 on the second side of the square steel plate is located within the square steel plate, and the anti-theft interface 11 and fixing hole 13 are both set in the area of ​​the square steel plate that is offset from the projection. When node device 2 is installed on the top surface of the square steel plate through the central coupling interface 12, there is still a margin around the square steel plate, and fixing holes 13 and anti-theft interfaces 11 can be installed in the remaining area around the plate. Therefore, interference between the pneumatic nail and the steel wire rope 32 lock and the body of node device 2 is avoided, ensuring the stability and coupling of the device.

[0071] Based on the above embodiments, a preferred embodiment of this device is provided below.

[0072] like Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The top and front views of the preferred design of the connecting motherboard are shown respectively. The selected node device 2 has a housing with a side length of 98mm and a diagonal length of 138mm. An anti-theft nut is provided on the inner edge of one side of the square steel plate, and four fixing holes 13 are provided on the inner edges of the four diagonals. Considering stability, the side length of the square steel plate is designed to be 160mm. Considering robustness and durability, the thickness of the square steel plate is designed to be 8mm. The diameter of the four fixing holes 13 at the four diagonals of the square steel plate is 8mm, and the hole spacing is 142mm. Bolts are used as the coupling interface 12, and the bolt type is M10*1mm. Nuts are used as the anti-theft interface 11, with an outer diameter of 10mm and an inner diameter of 5mm.

[0073] The method of using this device is as follows:

[0074] By using bolts fixed in the center of the square steel plate, a seamless and smooth connection is achieved with node device 2, forming an integral structure.

[0075] Four fixing holes 13 are made at the four opposite corners of the square steel plate. Air nails (sourced from online purchase) are driven in using an air gun. The square steel plate is tightly and stably connected to the hard ground, ensuring that the device can be efficiently coupled with the ground.

[0076] Nuts welded to the side of a square steel plate are used, and these nuts are connected to pre-drilled holes 21 on the housing of node device 2 via steel wire rope 32 (sourced from online shopping). Node device 2 and connecting main board 1 are connected as a whole by bolts and steel wire rope 32, and the connecting main board 1 is securely fixed to a hard surface with four pneumatic nails, forming an effective anti-theft barrier and ensuring the security of node device 2.

[0077] In the specific implementation process, taking the 2023 Ordos Basin Yishan Slope Qingyang Area 3D Seismic Acquisition Project as an example, this project is the first large-scale complex urban 3D project in the Ordos Basin, and also the largest urban area 3D project in western China in history. The project covers Qingyang City, which has a permanent population of 514,000 and a vast area of ​​75 square kilometers. All 18,528 points designed are located in the dense urban building clusters and hard surfaces such as cement and asphalt roads. From laying to withdrawal, the data points were left in the urban area for 10 days.

[0078] During construction, all eSeis node devices 2 were installed using this device, resulting in high-quality seismic data and achieving the expected coupling effect. During the 10-day retention period, only 14 nodes were damaged by large construction machinery at the construction site. The remaining 18,514 node devices 2 were safely recovered and their data was downloaded completely, thus achieving the expected protection of the node devices 2.

[0079] Through its application in a 3D project in Qingyang, this device ensures that the eSeis node device 2 achieves good coupling with hard ground in complex environments, thereby guaranteeing the quality of received seismic data. Simultaneously, it effectively provides anti-theft protection, demonstrating the device's high reliability, security, and practicality.
