[0036] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] The present invention provides a temporary support device and a temporary support protection method, which makes archaeological excavation safer and ensures the smooth progress of archaeological excavation work to the greatest extent.

[0039] The following combination Figures 1 to 6 The embodiments of the present invention will be further described below.

[0040] Figure 1 This is a schematic diagram of the unfolded shape of the umbrella-shaped frame of the temporary support device in one embodiment of the present invention. This embodiment includes a support 1; a vertical lifting rod 2, the first end of which is movably connected to the support 1; a receiving hole at the second end of the vertical lifting rod 2, within which a support structure 3 is retractably installed; a mechanical parameter detection device (not shown in the figure), which is mounted on the support structure 3; the mechanical parameter detection device is used to detect the mechanical parameters of the inner wall of an ancient tomb or pagoda; a control device 4, which is connected to the mechanical parameter detection device; used to determine whether to send an alarm signal based on the mechanical parameters and a first preset threshold; and a warning device 5, which is connected to the control device 4; used to receive the alarm signal when the control device 4 sends the alarm signal, and to issue a warning message based on the alarm signal.

[0041] The vertical lifting rod 2 is a telescopic rod-shaped body. The first end of the vertical lifting rod 2 is movably connected to the support 1, that is, the first end of the vertical lifting rod 2 can slide or roll relative to the support 1 to realize relative movement between the vertical lifting rod 2 and the support 1. In actual use, an opening is made at the top of the ancient tomb or pagoda, and the support 1 is set up on the opening. The vertical lifting rod 2 can be adjusted so that the vertical lifting rod 2 can be inserted into the ancient tomb or pagoda through the opening.

[0042] The mechanical parameters of the inner wall of an ancient tomb or pagoda can be the amount of deformation and / or the magnitude of stress.

[0043] The control device 4 has data receiving and processing functions and control functions. It can process data collected by mechanical parameter monitoring equipment, vertical lifting rod and three-dimensional laser scanner and control their movement.

[0044] The early warning device 5 can be a display device, a voice prompt device, or a vibration device, etc.

[0045] During use, the mechanical parameter detection equipment enters the ancient tomb or pagoda along with the vertical lifting rod 2, and adjusts the position of the mechanical parameter detection equipment with the movement of the umbrella-shaped frame, so that the mechanical parameter detection equipment can detect the mechanical parameters of the inner wall of the ancient tomb or pagoda. Specifically, the position of the mechanical parameter detection equipment can be adjusted by adjusting the position of the vertical lifting rod up and down and the posture of the umbrella-shaped frame.

[0046] The first preset threshold is the mechanical parameter corresponding to the internal wall of an ancient tomb or pagoda when it is in normal condition.

[0047] If the detected mechanical parameters exceed the first preset threshold, the control device sends an alarm signal to the early warning device. After receiving the alarm signal, the early warning device issues an early warning message, thereby prompting the staff inside the ancient tomb or pagoda to evacuate.

[0048] Compared to existing technologies, this method utilizes mechanical parameter detection equipment to measure the mechanical parameters of the inner walls of ancient tombs or pagodas. When an alarm signal is detected and sent to the control device, the system receives the alarm signal and issues a warning message. Archaeological technicians can then evacuate promptly based on this warning. Furthermore, the umbrella-like structure's support for the inner walls of the tomb / pagoda, along with the covering's shielding effect, effectively prevents the falling brick and stone debris, thereby improving safety during the archaeological excavation process and protecting the lives of archaeological technicians.

[0049] The vertical lifting rod is moved to a position above the center of the top of the ancient tomb structure by the movement of the steel frame and its rollers, so that it can be extended into the interior of the ancient tomb or pagoda structure.

[0050] To facilitate the movement of the vertical lifting rod, in some embodiments, the bracket is provided with a groove, and a roller is provided at the first end of the vertical lifting rod, the roller being rotatably disposed within the groove.

[0051] To save on operational steps, in some embodiments, the support structure includes an umbrella-shaped frame; the mechanical parameter detection device is located in the umbrella-shaped frame.

[0052] To facilitate detection operations, in some embodiments, a motor and an electric push rod are provided in the corresponding receiving hole. One end of the motor is connected to one end of the electric push rod, and the other end is connected to the control device. The other end of the electric push rod is connected to the umbrella-shaped frame, which can push the umbrella-shaped frame out of the receiving hole so that the umbrella-shaped structure can unfold.

[0053] In some examples, the structural stability of the umbrella-shaped frame is fully considered. The umbrella-shaped frame consists of three parts: the umbrella handle, the umbrella ribs, and the umbrella canopy. The umbrella handle adopts a telescopic rod structure for ease of use. The number and length of the umbrella ribs are determined by the structure of the ancient tomb. The umbrella canopy is covered with a membrane structure.

[0054] To ensure a uniform load distribution on the support structure, see... Figure 2 In some embodiments, the umbrella-shaped frame includes at least two support rods 21, the ends of which are connected; in order to block debris falling from the top of the ancient tomb and prevent injury to archaeologists, a membrane 22 is provided between the support rods in this embodiment.

[0055] In some cases, the coating material can be a membrane structure material consisting of a base fabric and a coating. The base fabric material includes polyester fiber and glass fiber, and the surface coating material includes polyvinyl chloride and polytetrafluoroethylene.

[0056] To facilitate the collection of information from the device, some embodiments include a distance acquisition device mounted on the vertical lifting rod and connected to the control device. The distance acquisition device is used to acquire the distance from itself to the inner wall of the ancient tomb or pagoda. The control device is used to determine whether the vertical lifting rod is in a predetermined position based on the distance and a second preset threshold, and to adjust the unfolding posture of the umbrella-shaped frame.

[0057] The second preset threshold is the distance at which the mechanical parameter detection equipment on the supporting structure can detect the mechanical parameters and prevent the vertical lifting rod from being damaged in the structure.

[0058] If the distance detected by the distance acquisition device is greater than or equal to the second preset threshold, the control device controls the distance detection device to stop detecting the distance and controls the motor to stop advancing the vertical lifting rod. In some cases, the vertical lifting rod can be moved on the support to adjust the vertical lifting rod to a suitable position.

[0059] When the distance acquisition device detects that the internal space of the ancient tomb or pagoda structure is sufficient to support the opening of the umbrella-shaped frame, it stops extending the vertical lifting rod, and at the same time, the umbrella-shaped frame moves out and unfolds.

[0060] To quickly detect the three-dimensional dimensions inside the structure, in some embodiments, the distance acquisition device includes a three-dimensional laser scanner, which is located at the second end of the vertical lifting rod.

[0061] To improve the warning effect of the warning device, in some embodiments, the warning device is located at the second end of the vertical lifting rod, and the warning device is arranged adjacent to the three-dimensional laser scanner; or, the warning device and the three-dimensional laser scanner are arranged symmetrically along the vertical lifting rod.

[0062] Based on the distance from the device to the inner wall of the ancient tomb / pagoda obtained by the 3D laser scanner, the vertical lifting rod reaches the predetermined position, the umbrella-shaped frame unfolds to the predetermined posture, and the stress detection device and deformation detection device start detection. When the stress value and deformation value exceed the warning value, the warning device will issue a signal to prompt personnel to leave.

[0063] Combination Figure 3 and Figure 4 As shown, in order to make the three-dimensional laser scanning device work more efficiently, in some embodiments, the temporary support device further includes a bearing 31 and a drive device (not shown in the figure); the inner ring of the bearing 31 is sleeved on the second end of the vertical lifting rod 32, and the outer ring is connected to the three-dimensional laser scanner 33; the drive device is located in the housing of the three-dimensional laser scanner 33 and is physically connected to the three-dimensional laser scanner 33 and electrically connected to the control device.

[0064] During operation, the drive device receives control signals from the control device and drives the 3D laser scanner 33 to move according to the control signals. Since the 3D laser scanner 33 is located on the outer ring of the bearing, the 3D laser scanner 33 can move circumferentially along the vertical lifting rod 32, thereby realizing the 3D laser scanner 33 rotating 360 degrees around the vertical lifting rod.

[0065] In order to enable the 3D laser scanning device to maintain its rotation, in some embodiments, the drive device includes an electric motor; the 3D laser scanner can perform a 360-degree horizontal rotation about the axis of the vertical lifting rod by means of an electric motor installed inside its structure.

[0066] In order to keep the electric motor running continuously, in some embodiments, the inner wall of the vertical lifting rod is provided with a wire groove with a rectangular cross-section to connect the control device and the electric motor.

[0067] After the 3D laser scanner scans the internal structure of the ancient tomb or pagoda, it transmits the distance information to the control device. Based on the distance between the umbrella-shaped frame and the inner wall of the ancient tomb or pagoda structure, the control device controls the horizontal and vertical movement of the umbrella-shaped frame. The umbrella-shaped frame will automatically move closer to the inner wall of the ancient tomb or pagoda until the elastic pad on the umbrella-shaped frame is tightly attached to the inner wall of the ancient tomb or pagoda structure.

[0068] To ensure the data collected by the mechanical parameter testing equipment is more accurate, please refer to... Figure 5 In some embodiments, the mechanical parameter detection device includes a stress detection element 51 and / or a deformation detection element 52; the stress detection element 51 and / or the deformation detection element 52 are disposed in the umbrella-shaped frame, and the sensor is an elastic pad 53; the stress detection element 51 is tubular or cylindrical, wrapped with a flexible material, and its diameter is the same as or smaller than the diameter of the umbrella-shaped support rod. When collecting data, the stress generated on the inner wall of the ancient tomb or pagoda is detected through the elastic pad covering its surface; the deformation detection element 52 is thin cylindrical or strip-shaped, installed in the umbrella-shaped frame, and its diameter matches the inner diameter of the hole reserved in the stress detection device, or it is independent of the stress detection device and monitors deformation by sensing the shape change of the umbrella-shaped frame.

[0069] Combination Figure 5 See Figure 6 In order to prevent the supporting structure from directly hitting the inner wall of the ancient tomb or pagoda and causing damage, in some embodiments, the elastic pad 53 is provided on the surface of the stress detection element 51, and the elastic pad 53 and the surface of the stress detection element 51 are flexibly connected.

[0070] To enable the stress detection element to better sense stress, in some embodiments, the mechanical parameter detection device includes the stress detection element for contacting the inner wall of the ancient tomb or pagoda to detect the contact stress between the umbrella-shaped frame and the inner wall of the ancient tomb or pagoda; an elastic pad is provided on the surface of the stress detection element, and both the stress detection element and the elastic pad are placed on the side closer to the ancient tomb.

[0071] In some cases, the elastic pad includes a removable latex pad to facilitate the detection of pressure generated on the inner walls of ancient tombs or pagodas.

[0072] Once the elastic pad is in close contact with the inner wall of the ancient tomb or pagoda structure, the stress detection element and deformation detection element on the umbrella-shaped frame are activated, and the stress and deformation values ​​are transmitted to the control equipment in real time.

[0073] To make the changes detected by the mechanical parameter detection device more intuitive, in some embodiments, the mechanical parameter detection device includes the stress detection element and the deformation detection element, both placed inside the umbrella-shaped frame; the stress detection element is located on the side of the umbrella-shaped frame near the inner wall of the ancient tomb or pagoda, and the deformation detection element is located on the side of the umbrella-shaped frame near the inner wall of the ancient tomb or pagoda.

[0074] In some examples, to facilitate the installation of mechanical parameter testing equipment and reduce the space occupied by the testing equipment, the deformation detection element is a thin cylinder or strip; the stress detection element is placed perpendicular to the side surface of the deformation detection element.

[0075] The number of stress detection elements and / or deformation detection elements is not limited, and the number is selected according to the structural size of the ancient tomb / pagoda.

[0076] A temporary support and protection method can be implemented using the protection device in the above embodiments. The method in this embodiment may include the following steps:

[0077] S11. Obtain the mechanical parameters of the inner wall of the ancient tomb or pagoda as detected by the mechanical parameter testing equipment.

[0078] S12. Based on the relationship between the mechanical parameters and the first preset threshold, determine whether to send an alarm signal to the early warning device.

[0079] S13. When the mechanical parameter is greater than the first preset threshold, an alarm signal is sent to the early warning device so that the early warning device issues an early warning message based on the alarm signal.

[0080] In this embodiment, by acquiring the mechanical parameters of the inner wall of the ancient tomb or pagoda detected by the mechanical parameter detection device, and determining whether to send an alarm signal to the early warning device based on the relationship between the mechanical parameters and a first preset threshold, an alarm signal is sent to the early warning device when the mechanical parameters are greater than the first preset threshold. In this way, the early warning device can issue an early warning message based on the alarm signal, and archaeological technicians can evacuate in time based on the early warning message, thereby improving the safety of the archaeological excavation process and providing protection for the lives of archaeological technicians.

[0081] In some examples, before acquiring the mechanical parameters of the inner wall of the ancient tomb or pagoda detected by the mechanical parameter detection device, the method further includes: acquiring the distance from itself to the inner wall of the ancient tomb or pagoda collected by the distance acquisition device; and determining whether the vertical lifting rod is in a predetermined position based on the distance and a second preset threshold.

[0082] In some examples, before obtaining the mechanical parameters of the inner wall of the ancient tomb or pagoda detected by the mechanical parameter detection device, the method further includes: when the vertical lifting rod is in a predetermined position, controlling the support structure to extend from the receiving hole at the second end of the vertical lifting rod, so that the mechanical parameter detection device can detect the mechanical parameters of the inner wall of the ancient tomb or pagoda.

[0083] In some examples, the support structure is an umbrella-shaped frame; the control support structure extends from a receiving hole at the second end of the vertical lifting rod, including: controlling a motor to rotate so that an electric push rod extends and unfolds the umbrella-shaped frame from the receiving hole at the second end of the vertical lifting rod.

[0084] In some examples, before acquiring the mechanical parameters of the inner wall of the ancient tomb or pagoda detected by the mechanical parameter detection device, the method further includes: adjusting the position and unfolding posture of the umbrella-shaped frame according to the distance from the acquisition device to the inner wall of the ancient tomb or pagoda, so that the mechanical parameter detection device fits into the inner wall of the ancient tomb or pagoda.
