Description

Technical Field

[0001] The utility model relates to the technical field of tunnel detection, in particular to a universal connector for a geological radar antenna. Background Art

[0002] A tunnel is an artificial underground passageway, mainly used for transportation (such as roads, railways, subways) or for water flow (such as hydropower generation or drainage). They usually pass through mountains, underground or underwater to provide a shorter, more direct or safer route.

[0003] Geological detection in tunnels is very important. By detecting the geology in tunnels, it helps to predict possible problems that may occur during the use of tunnels, such as water seepage, corrosion, etc., so as to formulate long-term maintenance and monitoring plans.

[0004] The existing method for tunnel detection is to use radar detection to detect different parts such as the arch and side walls in the tunnel. When using radar for detection, it is necessary to manually hold up the antenna for detection. During the detection process, since a straight rod is manually connected to the rotating part of the radar to make the radar form a certain angle with the straight rod for detecting the arch in the tunnel. At this time, since the angle between the radar and the straight rod is a fixed angle, during the detection process, one side of the radar will tilt relative to the arch, making the tilted side of the radar unable to fit the surface of the tunnel arch, resulting in errors in the detection results.

[0048] Please refer to Figures 1 - 3 , an embodiment of this utility model provides a universal connector 100 for a ground penetrating radar antenna. The universal connector 100 for the ground penetrating radar antenna includes:

[0049] A hand-held rod 110 having a hand-held end 110a and a mounting end 110b;

[0050] An elastic deformation component 120 having a first connection end 120a and a second connection end 120b, and the first connection end 120a is detachably connected to the mounting end 110b;

[0051] A fixed rod 130, one end of which is provided on the radar 200 and the other end is detachably connected to the second connection end 120b;

[0052] Wherein, the elastic deformation component 120 can generate deformation to make the fixed rod 130 tilt relative to the hand-held rod 110 around the elastic deformation component 120, so that the radar 200 completely fits the arch of the tunnel.

[0053] In this embodiment, the elastic deformation component 120 has a first connection end 120a and a second connection end 120b, and the first connection end 120a is detachably connected to the mounting end 110b;

[0054] A fixed rod 130, one end of which is provided on the radar 200 and the other end is detachably connected to the second connection end 120b;

[0055] Wherein, the elastic deformation component 120 can generate deformation to make the fixed rod 130 tilt relative to the hand-held rod 110 around the elastic deformation component 120, so that the radar 200 completely fits the arch of the tunnel.

[0056] During the operation, the operator holds the handheld rod 110 and adjusts the angle and position of the fixed rod 130 (and the radar 200) through the elastic deformation component 120 to ensure the close fit of the radar 200 with the tunnel arch. The elastic deformation component 120 provides the necessary flexibility, allowing the elastic deformation component 120 itself to deform, so that the fixed rod 130 is inclined relative to the handheld rod 110, enabling the radar 200 to adapt to different shapes and angles inside the tunnel. When conducting tunnel detection, the operator can achieve precise adjustment of the radar 200 angle through simple operation of the handheld rod 110, improving the accuracy and efficiency of detection.

[0057] Due to the application of the elastic deformation component 120, the radar 200 can better fit the tunnel arch, reducing the detection errors caused by incorrect angles.

[0058] The operator can adjust the relative position and angle between the handheld rod 110 and the fixed rod 130 to adapt to different detection environments and requirements.

[0059] It should be noted that the handheld rod 110 has a handheld end 110a and a mounting end 110b.

[0060] The handheld end 110a facilitates the operator to carry and control, and the mounting end 110b is used to connect the elastic deformation component 120.

[0061] The handheld rod 110 is rod-shaped.

[0062] The elastic deformation component 120 connects the handheld rod 110 and the fixed rod 130, and allows relative movement and angle adjustment between the handheld rod 110 and the fixed rod 130 through the elastic deformation component 120.

[0063] Enable the radar 200 to adjust the angle more flexibly, ensuring the close fit of the radar 200 with the tunnel arch.

[0064] One end of the fixed rod 130 is connected to the radar 200, and the other end is detachably connected to the second connection end 120b of the elastic deformation component 120.

[0065] Provide a stable connection between the radar 200 and the elastic deformation component 120, while allowing the radar 200 to adjust the angle.

[0066] In at least one embodiment of the present application, the elastic deformation component 120 includes:

[0067] The first mounting member 121, having the first connection end 120a, and the first mounting member 121 is detachably connected to the handheld rod 110 through the first connection end 120a;

[0068] The elastic deformation member 122, one end of which is disposed on the first mounting member 121;

[0069] The second mounting member 123 has the second connection end 120b. The second mounting member 123 is detachably connected to the fixing rod 130 through the second connection end 120b. One end of the elastic deformation member 122 away from the first mounting member 121 is arranged on the second mounting member 123. The elastic deformation member 122 can generate deformation around the axis direction perpendicular to the hand-held rod 110.

[0070] Please refer to Figures 1 - 5 , in this embodiment, during use, the operator first connects the first mounting member 121 to the hand-held rod 110, and then connects the fixing rod 130 to the radar 200 through the elastic deformation member 122 and the second mounting member 123. When it is necessary to adjust the radar 200 to better fit the tunnel arch, the operator can adjust the angle of the entire device through the hand-held rod 110. Due to the existence of the elastic deformation member 122, the fixing rod 130 can perform necessary deformation and angle adjustment relative to the hand-held rod 110, so as to achieve a perfect fit between the radar 200 and the tunnel arch. This makes the detection of the radar 200 more accurate, the operation more flexible, and at the same time increases the reliability and durability of the device.

[0071] Through the elastic deformation member 122, the antenna of the radar 200 can more flexibly adjust its angle with the tunnel arch, thereby improving the detection accuracy.

[0072] The operator can more easily adjust the position and angle of the radar 200 to adapt to different detection environments and requirements.

[0073] It should be noted that the first mounting member 121 is rod-shaped and connects the hand-held rod 110 and the elastic deformation member 122. The first mounting member 121 includes a first connection end 120a, which can be detachably connected to the mounting end 110b of the hand-held rod 110. The first mounting member 121, as the connection between the hand-held rod 110 and the elastic deformation member 122, provides a stable support point.

[0074] The elastic deformation member 122 is a spring, which provides elastic deformation and allows the radar 200 to perform angle adjustment. One end of the elastic deformation member 122 is mounted on the first mounting member 121. Allowing elastic deformation enables the fixing rod 130 to adjust the angle between the fixing rod 130 and the hand-held rod 110 around the axis direction perpendicular to the hand-held rod 110 while maintaining stability.

[0075] The second mounting member 123 connects the fixing rod 130 and the elastic deformation member 122. The second mounting member 123 includes a second connection end 120b, which is detachably connected to the connection end of the fixing rod 130. The second mounting member 123 provides a connection point between the fixing rod 130 and the elastic deformation member 122, enabling the fixing rod 130 to deform around the elastic deformation member 122.

[0076] In at least one embodiment of the present application, a first positioning groove 121a is provided at one end of the first mounting member 121 away from the first connection end 120a, and one end of the elastic deformation member 122 is fixedly disposed in the first positioning groove 121a.

[0077] In at least one embodiment of the present application, a second positioning groove 123a is provided at one end of the second mounting member 123 away from the second connection end 120b, and one end of the elastic deformation member 122 is fixedly disposed in the second positioning groove 123a.

[0078] Please refer to Figures 1 - 5 , in this embodiment, during use, the elastic deformation member 122 is fixed at both ends in the first positioning groove 121a and the second mounting groove respectively, ensuring the stability and accuracy of the elastic deformation member 122 during deformation. The operator adjusts the angle of the radar 200 antenna by moving the handheld rod 110 and the fixed rod 130. Since both ends of the elastic deformation member 122 are fixed in the first positioning groove 121a and the second positioning groove 123a respectively, its deformation is precise and controlled. The radar 200 antenna is allowed to closely fit the arch of the tunnel at the correct angle and position, thus ensuring high-precision detection results.

[0079] The first positioning groove 121a and the second positioning groove 123a ensure that the elastic deformation member 122 can maintain the correct direction and displacement limit during deformation, which is crucial for precisely adjusting the angle of the radar 200 antenna.

[0080] It should be noted that the first positioning groove 121a of the first mounting member 121 is a groove for placing and fixing one end of the elastic deformation member 122.

[0081] The first positioning groove 121a is located at one end of the first mounting member 121, away from the part connected to the handheld rod 110.

[0082] The first positioning groove 121a provides a fixed point for the elastic deformation member 122, preventing the elastic deformation member 122 from sliding or misaligning during operation, thus ensuring the stability and accuracy of the radar 200 system.

[0083] The second positioning groove 123a of the second mounting member 123 is a groove for fixing the other end of the elastic deformation member 122.

[0084] The second positioning groove 123a is located at one end of the second mounting member 123, away from the part connected to the fixed rod 130.

[0085] The second positioning groove 123a ensures the stability of the elastic deformation member 122 when connected to the fixed rod 130, preventing any unnecessary displacement or distortion of the elastic deformation member 122 during the deformation process.

[0086] In at least one embodiment of the present application, the depth of the first positioning groove 121a is denoted as a, the depth of the second positioning groove 123a is denoted as b, and the length of the elastic deformation member 122 is denoted as c, satisfying the relationship: a + c < b ≤ 2.5(a + c).

[0087] Please refer to Figures 1 - 5 , in this embodiment, in actual operation, when the operator needs to adjust the angle of the radar 200 antenna, they will achieve this purpose by moving the handheld rod 110 and the fixed rod 130. Since the length of the elastic deformation member 122, the depths of the first positioning groove 121a and the second positioning groove 123a satisfy the relationship: a + c < b ≤ 2.5(a + c). It ensures that the radar 200 antenna can closely fit the arch of the tunnel at the correct angle and position, thus ensuring the accuracy of detection. To ensure the degree of deformation of the elastic deformation member 122, while ensuring the stability of the radar 200 and the fixed rod 130.

[0088] The degree and direction of deformation of the elastic deformation member 122 can be precisely controlled. It ensures the accuracy and stability of the radar 200 antenna when adjusting the angle.

[0089] Ensure that the elastic deformation member 122 will not be overstretched or overcompressed during deformation, maintaining an appropriate tension, thereby improving the responsiveness and sensitivity of the device.

[0090] It should be noted that the depth (a) of the first positioning groove 121a: This is the depth of the first positioning groove 121a on the first mounting member 121.

[0091] The depth (b) of the second positioning groove 123a: This is the depth of the second positioning groove 123a on the second mounting member 123.

[0092] The length (c) of the elastic deformation member 122: This is the length of the elastic deformation member 122 connecting the first and second mounting members 123.

The second threaded portion 120d is received in the second threaded groove 130a and is threadedly connected to the fixing rod 130.

[0095] Please refer to Figures 1 - 5 , in this embodiment, during use, the operator first screws the first threaded portion 120c of the first connection end 120a into the first threaded groove 110c of the handheld rod 110, and then screws the second threaded portion 120d of the second connection end 120b into the second threaded groove 130a of the fixing rod 130. The threaded connection ensures the stability and reliability of the entire device, enabling the radar 200 device to maintain an appropriate position and angle during geological detection. The threaded connection not only makes the entire system more stable but also provides sufficient flexibility to adapt to different usage scenarios and requirements. In addition, it is convenient for users to quickly assemble, disassemble, and maintain when needed, thereby improving the practicality and maintenance efficiency of the entire system.

[0096] The threaded connection provides a firm and reliable method to ensure the stability among the handheld rod 110, the elastic deformation assembly 120, and the fixing rod 130.

[0097] The threaded connection makes the assembly and disassembly simple, facilitating maintenance and replacement of components.

The guiding of the connecting rope 140 between the first and second annular portions 111 ensures stable transmission and operation. In this way, when performing geological detection, the operator can easily adjust the radar 200 antenna to ensure that it can be completely attached to the arch of the tunnel. This not only improves the accuracy of detection, but also increases the flexibility and convenience of operation.

[0111] Through the connecting rope 140 and the winch 150, the operator can more flexibly adjust the position and angle of the radar 200 antenna to adapt to different detection environments and requirements.

[0126] Please refer to Figures 1 - 5 , in this embodiment, the elastic deformation component 120 has a first connection end 120a and a second connection end 120b, and the first connection end 120a is detachably connected to the mounting end 110b;

[0127] The fixed rod 130 has one end disposed on the radar 200 and the other end detachably connected to the second connection end 120b;

[0128] Wherein, the elastic deformation component 120 can generate deformation, so that the fixed rod 130 tilts relative to the handheld rod 110 around the elastic deformation component 120, so that the radar 200 completely fits the arch of the tunnel.

[0129] During the operation, the operator holds the handheld rod 110 and adjusts the angle and position of the fixed rod 130 (and the radar 200) through the elastic deformation component 120 to ensure the close fit between the radar 200 and the tunnel arch. The elastic deformation component 120 provides the necessary flexibility, allowing the elastic deformation component 120 itself to deform, so that the fixed rod 130 tilts relative to the handheld rod 110, so that the radar 200 can adapt to different shapes and angles inside the tunnel. When performing tunnel detection, the operator can accurately adjust the angle of the radar 200 through simple operation of the handheld rod 110, improving the accuracy and efficiency of detection.
