Description

Technical Field

[0001] This utility model relates to the field of trenchless vehicle technology, and more specifically, to an electrical control system for trenchless equipment. Background Technology

[0002] Trenchless technology is an engineering technology system that enables the laying, repair, replacement, and detection of underground pipelines without excavation or with minimal excavation of the surface. Its core characteristic is "minimally invasive," which reduces the damage to the surface environment caused by traditional excavation construction and has become a key technological support in the field of modern underground engineering.

[0003] The implementation of trenchless technology relies on trenchless equipment, which includes a wide variety of equipment. Generally, it is divided into trenchless main equipment and trenchless auxiliary equipment. Main equipment is the key machinery to realize the core construction functions, while auxiliary equipment provides guarantees, support or auxiliary operations for construction to ensure safe and efficient construction.

[0004] With the continuous improvement of trenchless construction technology, especially construction in high temperature, high humidity and harmful gas environments, it is also necessary to put it on the agenda. If the harsh environment is clearly identified or predicted in advance, measures can be taken in advance to deal with it, such as cooling, dust removal and ventilation. However, for occasional events, it is often difficult to predict and deal with them in advance, which poses certain safety hazards. Utility Model Content

[0005] The present invention aims to improve safety during trenchless construction.

[0006] To solve the above problems, this utility model provides an electrical control system for trenchless equipment, comprising:

[0007] Tunnel layer controller and main drive frequency converter installed on trenchless main equipment;

[0008] Auxiliary soft starters and auxiliary drive frequency converters installed on trenchless auxiliary equipment;

[0009] An execution unit and a fault detection unit are installed on the trenchless main equipment and / or the trenchless auxiliary equipment, and the fault detection unit is electrically connected to the corresponding execution unit;

[0010] Ground level controller and ground integrated control system;

[0012] The electrical control system for excavation equipment provided by this utility model has at least the following beneficial effects:

[0013] The tunnel-level controller can be a controller located on the trenchless main equipment inside the tunnel. It receives parameters from the main drive inverter on the trenchless main equipment, the auxiliary soft starter and auxiliary drive inverter on the trenchless auxiliary equipment, the execution units, and the fault detection unit. Based on these parameters, it can control the relevant equipment inside the tunnel, enabling equipment start-up and shutdown, parameter adjustment, etc. For example, when the fault detection unit detects an anomaly in the data of the corresponding execution unit, the tunnel-level controller can control the execution unit to perform corresponding actions, promptly adjusting it to restore it to normal operating status. In addition, there is a ground-level controller and a ground-level integrated control system at the construction site. This allows the parameters or information received by the tunnel-level controller to be synchronously transmitted to the ground-level controller. The ground-level controller, acting as a relay station between the tunnel and the ground, can further feed these parameters and information back to the ground-level integrated control system for display. Ground personnel can then interact with the ground-level integrated control system based on this information to ultimately control the tunnel-level controller, achieving double protection for safe operation.

The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly.

[0038] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0039] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components.

[0042] See Figure 1 An embodiment of the present invention provides an electrical control system for trenchless equipment, comprising:

[0043] Tunnel layer controller 11 and main drive frequency converter 12 are installed on the trenchless main equipment;

[0044] Auxiliary soft starter 13 and auxiliary drive frequency converter 14 installed on trenchless auxiliary equipment;

[0045] An execution unit 15 and a fault detection unit 16 are installed on the trenchless main equipment and / or the trenchless auxiliary equipment, and the fault detection unit 16 is electrically connected to the corresponding execution unit 15.

[0046] Ground layer controller 17 and ground integrated control system 18;

[0047] The main drive inverter 12, the auxiliary soft starter 13, the auxiliary drive inverter 14, the execution unit 15, and the fault detection unit 16 are electrically connected to the tunnel layer controller 11, the ground layer controller 17 is electrically connected to the tunnel layer controller 11, and the ground integrated control system 18 is electrically connected to the ground layer controller 17.

[0048] In this embodiment, the tunnel layer controller 11 can be a controller on the trenchless main equipment located in the tunnel. It can receive some parameters from the main drive inverter 12 on the trenchless main equipment, the auxiliary soft starter 13 and auxiliary drive inverter 14 on the trenchless auxiliary equipment, the execution unit 15, and the fault detection unit 16. It can then control the relevant equipment in the tunnel according to these parameters to realize equipment start-up and shutdown, parameter adjustment, etc. For example, when the fault detection unit 16 detects that the data of the corresponding execution unit 15 is abnormal, the tunnel layer controller 11 can control the execution unit 15 to perform corresponding actions and adjust it to restore it to normal working state in a timely manner.

[0049] In addition, there is a ground-level controller 17 and a ground-level integrated control system 18 on the ground at the construction site. This allows the parameters or information received by the tunnel-level controller 11 to be synchronously transmitted to the ground-level controller 17. The ground-level controller 17, as a relay station between the tunnel and the ground, can further feed these parameters and information back to the ground-level integrated control system 18 for display. Based on this information, the workers on the ground can interact with the ground-level integrated control system 18 to ultimately control the tunnel-level controller 11, achieving double insurance for safe operation.

[0050] It should be noted that the improvements in this application mainly lie in the structural configuration, namely, a tunnel layer controller 11 and a main drive frequency converter 12 are installed on the trenchless main equipment, an auxiliary soft starter 13 and an auxiliary drive frequency converter 14 are installed on the trenchless auxiliary equipment, an execution unit 15 and a fault detection unit 16 are installed on the trenchless main equipment and / or the trenchless auxiliary equipment, and a ground layer controller 17 and a ground integrated control system 18 are installed on the ground. The signal transmission process and control logic between adjacent equipment or units are applications of existing technology, and there is no technical improvement.

[0051] The aforementioned structures on the trenchless main equipment can refer to structures on the same trenchless main equipment or structures on different trenchless main equipment. Similarly, the structures on the trenchless auxiliary equipment can refer to structures on the same trenchless auxiliary equipment or structures on different trenchless main equipment. Trenchless main equipment can be, for example, horizontal directional drilling equipment, pipe jacking / tunnel boring machines, and impact spears, while trenchless auxiliary equipment can be, for example, power and energy equipment, material transport and handling equipment, ventilation equipment, and drainage equipment. These trenchless main equipment or trenchless auxiliary equipment may include an execution unit 15, such as a hydraulic cylinder. Therefore, in this embodiment, the execution unit 15 can be a structural component of either the trenchless main equipment or the trenchless auxiliary equipment.

[0052] In the above-mentioned trenchless equipment electrical control system, the main drive frequency converter 12 can receive instructions from the tunnel layer controller 11 to smoothly adjust the motor speed / torque of the trenchless main equipment and avoid starting shock; the auxiliary soft starter 13 can receive instructions from the tunnel layer controller 11 to control the motor of the trenchless auxiliary equipment to start; after the motor of the trenchless auxiliary equipment starts, the auxiliary drive frequency converter 14 can receive instructions from the tunnel layer controller 11 to adjust the speed / torque of the motor of the trenchless auxiliary equipment.

[0053] See Figure 1 Optionally, the trenchless equipment electrical control system also includes a remote Internet of Things (IoT) monitoring system 19, which is electrically connected to the ground integrated control system 18.

[0054] In this embodiment, the remote IoT monitoring system 19 is a remote system that can receive system-wide data (equipment operation, fault alarms, construction progress, etc.) uploaded by the ground integrated control system 18, enabling remote real-time monitoring. For example, if the monitoring personnel at the remote IoT monitoring system 19 discover an anomaly in the trenchless equipment at the construction site, but the problem remains unresolved, it may indicate a malfunction in the tunnel layer controller 11. In this case, the system can alert the workers inside the tunnel to resolve the issue manually, further ensuring construction safety.

[0055] Optionally, the remote IoT monitoring system 19 is wirelessly connected to the ground integrated control system 18.

[0056] In this embodiment, since the remote IoT monitoring system 19 is a remote system, it is preferably connected to the ground integrated control system 18 at the construction site via wireless communication. The wireless communication connection method can be 4G, Wi-Fi, Bluetooth, or 5G.

[0057] Optionally, the main drive frequency converter 12 is connected to the tunnel layer controller 11 via a signal line;

[0058] Or / and, the auxiliary drive frequency converter 14 is connected to the tunnel layer controller 11 via a signal line;

[0059] Or / and, the auxiliary drive frequency converter 14 is connected to the tunnel layer controller 11 via a signal line;

[0060] Or / and, the execution unit 15 is connected to the tunnel layer controller 11 via a signal line;

[0061] Or / and, the fault detection unit 16 is connected to the corresponding execution unit 15 via a signal line;

[0062] Or / and, the fault detection unit 16 is connected to the tunnel layer controller 11 via a signal line;

[0063] Or / and, the ground layer controller 17 is connected to the tunnel layer controller 11 via a signal line;

[0064] Or / and, the ground integrated control system 18 is connected to the ground layer controller 17 via a signal line.

[0065] In this embodiment, the main drive inverter 12 and the tunnel layer controller 11 are both located at the construction site and are relatively close to each other. They can be connected via signal lines to ensure stable communication signals between them. The auxiliary drive inverter 14 is also located at the construction site and is relatively close to the tunnel layer controller 11. They can also be connected via signal lines to ensure stable communication signals between them. The execution unit 15 is also located at the construction site and is relatively close to the tunnel layer controller 11. They can also be connected via signal lines to ensure stable communication signals between them. The fault detection unit 16 is also located at the construction site. It is relatively close to the tunnel layer controller 11 and the execution unit 15. Therefore, the fault detection unit 16 and the corresponding execution unit 15 can be connected via signal lines to ensure stable communication signals between them. The fault detection unit 16 and the tunnel layer controller 11 are also connected via signal lines to ensure stable communication signals between them. The ground layer controller 17 is also located at the construction site. It is relatively close to the tunnel layer controller 11 and the ground integrated control system 18. Therefore, the ground layer controller 17 can be connected to the tunnel layer controller 11 and the ground integrated control system 18 via signal lines to ensure stable communication signals.

[0066] See Figure 2 Optionally, it also includes a first signal line 21 and a second signal line 22, one end of the first signal line 21 is connected to the tunnel layer controller 11, one end of the second signal line 22 is connected to the ground layer controller 17, and the other ends of the first signal line 21 and the second signal line 22 are detachably connected.

[0067] In this embodiment, based on the ground layer controller 17 being connected to the tunnel layer controller 11 via a signal line, more specifically, the signal line between the two is detachable. That is, when the ground layer controller 17 and the tunnel layer controller 11 need to communicate, the first signal line 21 and the second signal line 22 can be connected together to conduct electricity; when the ground layer controller 17 and the tunnel layer controller 11 do not need to communicate, the first signal line 21 and the second signal line 22 can be separated.

[0068] It should be noted that during actual construction, since the equipment inside the tunnel sometimes needs to be moved while the equipment on the ground does not need to be moved, the first signal line 21 and the second signal line 22 can be separated in this case.

[0069] See Figure 2 Optionally, the first signal line 21 is provided with a male connector 211 at the end away from the tunnel layer controller 11, and the second signal line 22 is provided with a female connector 221 at the end away from the ground layer controller 17. The male connector 211 and the female connector 221 are detachably connected.

[0070] In this embodiment, the connection between the first signal line 21 and the second signal line 22 can be achieved by plugging in the male connector 211 and the female connector 221, which is simple and convenient. Correspondingly, the separation of the first signal line 21 and the second signal line 22 can be achieved by separating the male connector 211 and the female connector 221.

[0071] Optionally, the tunnel layer controller 11 is a microcontroller; or / and the ground layer controller 17 is a microcontroller.

[0072] Both the tunnel layer controller 11 and the ground layer controller 17 can be conventional microcontrollers. Microcontrollers have strong flexibility and programmability; moreover, microcontrollers are small in size, low in cost, and low in power consumption, which makes them very advantageous in some embedded control scenarios where cost and size requirements are high.

[0073] See Figure 3 Optionally, the tunnel layer controller 11 includes a controller body 111 and a controller housing 112, the controller body 111 is disposed inside the controller housing 112, and an epoxy resin layer 113 is disposed between the controller body 111 and the controller housing 112.

[0074] In this embodiment, the tunnel layer controller 11 is the core structure within the tunnel, and ensuring its normal operation in harsh environments is crucial. Based on this consideration, the tunnel layer controller 11 can be encapsulated with epoxy resin to prevent the generation of electrical sparks that could ignite flammable gases in the environment during operation. This also significantly improves the protection level, meeting the requirements for normal use in extremely harsh environments.

[0075] Specifically, the tunnel layer controller 11 may include a controller body 111 and a controller housing 112. The controller body 111 is, for example, a microcontroller. After the controller body 111 is installed in the controller housing 112, epoxy resin can be potted into the controller housing 112 to form an epoxy resin layer 113 surrounding the controller body 111.

[0076] See Figure 3 Optionally, the controller housing 112 includes an outer shell 1121 and an inner shell 1122 disposed in the outer shell 1121, the controller body 111 is disposed in the inner shell 1122, and the epoxy resin layer 113 is filled between the outer shell 1121 and the inner shell 1122.

[0077] In this embodiment, the controller housing 112 may specifically include an outer shell 1121 and an inner shell 1122 located inside the outer shell 1121. The controller body 111 is specifically installed in the inner shell 1122. The inner shell 1122 provides functions such as support and positioning for the controller body 111. The epoxy resin layer 113 can fill the space between the outer shell 1121 and the inner shell 1122, which can prevent the epoxy resin from directly contacting the controller body 111.

[0078] Optionally, the side wall of the outer casing 1121 is provided with a filling port (not shown in the figure).

[0079] In this embodiment, the side wall of the outer shell 1121 is provided with a potting port, so that epoxy resin can be potted between the outer shell 1121 and the inner shell 1122 through the potting port, which is convenient and reliable.

[0080] Although the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
