Description

Technical Field

[0001] This utility model relates to the field of fixed support technology, and in particular to a radar mounting bracket for the bottom of a foundation pit. Background Technology

[0002] Foundation pit engineering, as an indispensable part of modern urban construction, is defined as the process of developing underground space, such as subway construction and basement construction of high-rise buildings. During foundation pit construction, it is necessary to confirm whether there are hidden dangers such as underground cavities, rock strata interfaces, seepage channels, and isolated boulders at the bottom of the foundation pit. Ground penetrating radar can clearly identify the distribution changes of these underground media through the difference in electromagnetic pulse reflection, providing data support for the safety of foundation pit excavation.

[0003] Most existing radars are fixed to the ground by tripods. However, when conducting exploration and measurement on relatively loose ground, the radar fixed to the loose ground is prone to measurement errors due to equipment displacement because the ground is loose and the contact area between the tripod and the ground is limited.

[0004] An existing patent (publication number: CN216853119U) discloses a measuring tool for geological exploration. By setting a ground-pressing plate between the telescopic outriggers and the ground stakes, the contact area between the measuring tool and the ground can be increased, allowing the detection equipment to be fixed more stably on relatively loose ground such as sand and silt, reducing measurement errors caused by the movement of the detection equipment.

[0005] Existing patents offer solutions to the aforementioned problems, but their detection effects are unsatisfactory. In actual use, the ground at the bottom of the foundation pit often has local bulges and depressions. Due to the lack of an adjustment structure, the support is prone to tilting after installation. Since the ground-penetrating radar needs to keep the transmitting surface horizontal to ensure that the electromagnetic pulse propagates vertically downward, the tilt angle will cause the pulse propagation direction to deviate, and the reflected signal receiving position will deviate from the preset area, ultimately causing artifacts in the detection image, misjudging the distribution of underground media, affecting the accuracy of the detection data, and reducing the practicality of the device.

[0006] To address this, a radar mounting bracket for the bottom of a foundation pit is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a radar mounting bracket for the bottom of a foundation pit, which can solve the problems of poor detection effect of existing radar mounting brackets. In actual use, the ground at the bottom of the foundation pit often has local protrusions and depressions. Due to the lack of adjustment structure, the bracket is prone to tilting after installation. Since the ground-penetrating radar needs to keep the transmitting surface horizontal to ensure that the electromagnetic pulse propagates vertically downward, the tilt angle will cause the pulse propagation direction to deviate, the reflected signal receiving position to deviate from the preset area, and ultimately cause artifacts in the detection image, misjudgment of the underground medium distribution, affect the accuracy of the detection data, and reduce the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a radar mounting bracket for the bottom of a foundation pit, comprising a mounting frame, an adjusting component movably connected inside the mounting frame, and a square frame fixedly connected to the bottom of the mounting frame. The adjusting component includes a cover plate, movable plates fixedly connected to both sides of the bottom of the cover plate, and movable blocks fixedly connected to the bottom of opposite sides of the two movable plates. Springs are provided inside the two movable blocks, and the two movable blocks are slidably connected to both sides of the inner wall of the mounting frame. T-shaped blocks are fixedly connected to opposite sides of the two springs, and the other end of the T-shaped blocks extends to the outside of the mounting frame. A universal ball joint is fixedly connected to the bottom of the cover plate, and a radar body is fixedly connected to the other end of the universal ball joint. Adjustable legs are movably connected to the four corners of the bottom of the square frame, and a fixing component is fixedly connected to the other end of the adjusting legs.

[0009] Preferably, the fixing component includes a fixing plate, a conical cylinder is fixedly connected to the bottom of the fixing plate, and positioning blocks are movably connected to the four corners of the surface of the conical cylinder. A rotating circular block is rotatably connected inside the conical cylinder. A connecting rod is fixedly connected to the top of the rotating circular block, and the other end of the connecting rod extends to the top of the fixing plate and is fixedly connected to a rotating ring. A connecting plate is rotatably connected to the four corners of the surface of the rotating circular block, and the other end of the connecting plate is rotatably connected to the positioning block.

[0010] Preferably, a U-shaped plate is rotatably connected to the top of the fixed plate, and the side of the U-shaped plate away from the fixed plate is fixedly connected to the adjusting leg.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a fixing component, this application can use a conical cylinder to break into the ground to complete the initial installation. At the same time, rotating the rotating ring drives the positioning block to unfold, so that the positioning block is embedded in the surrounding soil, forming a double fixing structure. This enhances the stability of the device on the complex ground at the bottom of the foundation pit, avoids detection deviation caused by the displacement of the radar body due to the support, and improves the stability of the device.

[0020] 2. This application, by setting an adjustment component, allows the locking of the cover plate to be released by pressing the T-shaped block to compress the spring. After moving to the appropriate position, the spring rebounds and causes the T-shaped block to engage with the positioning hole on the surface of the mounting frame to complete the locking, thus realizing flexible adjustment of the height of the radar body. Combined with the angle adjustment function of the universal ball, the radar body can be rotated to the required detection direction, adapting to different detection needs at the bottom of the pit, ensuring that the radar body can be accurately aligned with the detection target, and improving the ease of use of the device.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A radar mounting bracket for the bottom of a foundation pit includes a mounting frame 1. An adjusting component 2 is movably connected inside the mounting frame 1, and a square frame 3 is fixedly connected to the bottom of the mounting frame 1. The adjusting component 2 includes a cover plate 201. Movable plates 202 are fixedly connected to both sides of the bottom of the cover plate 201, and movable blocks 203 are fixedly connected to the bottom of opposite sides of the two movable plates 202. Springs 204 are provided inside the two movable blocks 203, and the two movable blocks 203 are slidably connected to both sides of the inner wall of the mounting frame 1. T-shaped blocks 205 are fixedly connected to opposite sides of the two springs 204, and the other end of the T-shaped blocks 205 extends to the outside of the mounting frame 1. A universal ball joint 206 is fixedly connected to the bottom of the cover plate 201, and a radar body 207 is fixedly connected to the other end of the universal ball joint 206. Adjustable legs 4 are movably connected to the four corners of the bottom of the square frame 3, and a fixing component 5 is fixedly connected to the other end of the adjustable legs 4.

[0030] In this embodiment: by adjusting the cooperation between the support leg 4 and the U-shaped plate 6, the conical cylinder 502 rotates along the adjusting support leg 4 under the constraint of the U-shaped plate 6 to complete the orientation adjustment, so that the conical cylinder 502 can be accurately embedded in the soil to achieve initial positioning. At the same time, by rotating the rotating ring 506, the connecting rod 505 is driven to rotate, which drives the rotating block 504 to rotate smoothly, and synchronously drives the connecting plate 507 to move, thereby driving the positioning block 503 to unfold and embed into the surrounding soil, forming a double fixing structure. This avoids the radar body 207 from detection deviation caused by the displacement of the support, and improves the ease of use of the device. Then, by pressing T The T-shaped block 205 causes the spring 204 to retract, releasing the lock on the moving block 203. This allows the cover plate 201 to move smoothly under the constraint of the moving block 203. Once in position, the spring 204 rebounds, causing the T-shaped block 205 to reset and embed into the positioning hole 10 on the surface of the mounting frame 1, thus locking it in place. This allows for flexible adjustment of the height of the radar body 207. Simultaneously, the angle adjustment function of the universal ball joint 206 allows for adjustment of the angle of the radar body 207. Combined with the calibration of the level 11, this ensures that the radar body 207 can be accurately aligned with the detection target, guaranteeing the accuracy of the detection data and improving the practicality of the device.

[0031] Specifically, such as Figure 5 As shown, the fixing component 5 includes a fixing plate 501, a conical cylinder 502 fixedly connected to the bottom of the fixing plate 501, and positioning blocks 503 movably connected to the four corners of the surface of the conical cylinder 502. A rotating block 504 is rotatably connected inside the conical cylinder 502. A connecting rod 505 is fixedly connected to the top of the rotating block 504, and the other end of the connecting rod 505 extends to the top of the fixing plate 501 and is fixedly connected to a rotating ring 506. A connecting plate 507 is rotatably connected to the four corners of the surface of the rotating block 504, and the other end of the connecting plate 507 is rotatably connected to the positioning block 503.

[0032] Specifically, such as Figure 5 As shown, a U-shaped plate 6 is rotatably connected to the top of the fixed plate 501, and the side of the U-shaped plate 6 away from the fixed plate 501 is fixedly connected to the adjusting leg 4.

[0033] Specifically, such as Figure 5 As shown, the conical cylinder 502 has a fixed groove 7 inside, and the rotating block 504 is located inside the fixed groove 7.

[0034] Specifically, such as Figure 5 As shown, each of the four corners of the tapered cylinder 502 is provided with a movable hole 8 for use with the positioning block 503, and the movable hole 8 is connected to the fixed groove 7.

[0035] In this embodiment: the angle of the fixing component 5 can be flexibly adjusted by the cooperation of the U-shaped plate 6 and the adjusting leg 4, which facilitates the fixing of subsequent equipment. At the same time, the moving hole 8 is connected to the fixing groove 7, so that the rotating block 504 drives the connecting plate 507 to move smoothly, and simultaneously drives the positioning block 503 to move smoothly along the moving hole 8, realizing the deployment, anchoring and repositioning of the positioning block 503 in the soil, simplifying the installation operation and improving the convenience of using the fixing component 5.

[0036] Specifically, such as Figure 2 , Figure 3 As shown, both sides of the inner wall of the mounting frame 1 are provided with sliding grooves 9 for use with the movable block 203, and the surface of the movable block 203 is in contact with the inner wall of the sliding groove 9.

[0037] Specifically, such as Figure 2 , Figure 3 As shown, several positioning holes 10 are provided on both sides of the mounting frame 1 to cooperate with the T-shaped block 205, and the positioning holes 10 are connected to the slide groove 9.

[0038] Specifically, such as Figure 2 , Figure 4 As shown, a level 11 is fixedly connected to the front side of the radar body 207.

[0039] In this embodiment: the movable block 203 and the slide 9 work together to make the movable block 203 move smoothly under the restriction of the slide 9, and simultaneously drive the cover plate 201 and the radar body 207 to rise and fall. At the same time, it is connected to the slide 9 through the positioning hole 10. When it moves into place, the spring 204 rebounds and drives the T-shaped block 205 to reset and embed into the positioning hole 10 to complete the fixation of the position. This realizes the flexible adjustment of the height of the radar body 207. With the measurement structure formed by the level 11, the angle of the radar body 207 can be precisely adjusted to ensure that the radar body 207 can be accurately aligned with the detection target, ensuring the accuracy of the detection data and improving the practicality of the device.

[0040] Specifically, such as Figure 3 As shown, the four corners of the bottom of the square frame 3 are provided with rotating grooves 12 for use with the adjustable legs 4, and the adjustable legs 4 are rotatably connected inside the rotating grooves 12.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, each of the four adjustable legs 4 has an arc-shaped magnetic plate 13 fixedly connected to the top of its opposite side, and the four arc-shaped magnetic plates 13 are connected to each other by adsorption.

[0042] In this embodiment: by adjusting the support leg 4 and the arc-shaped magnetic plate 13 in cooperation, when the support leg 4 is closed, the arc-shaped magnetic plate 13 comes into contact with each other and uses its magnetic force to complete the adsorption and fixation, avoiding the support leg 4 from accidentally unfolding during the movement, which facilitates the movement of the equipment. At the same time, during use, by adjusting the support leg 4 and the rotating groove 12 in cooperation, the support leg 4 can rotate smoothly inside the rotating groove 12, which completes the flexible adjustment of the angle, adapts to the complex ground at the bottom of the foundation pit, facilitates the installation of the equipment, and improves the ease of use of the device.

[0043] Working Principle: When inspecting a foundation pit, the device is first moved to the target detection area at the bottom of the pit. Then, the conical cylinder 502 is manually rotated, allowing it to rotate along the adjusting leg 4 under the constraint of the U-shaped plate 6. This allows for flexible adjustment of the orientation of the conical cylinder 502, ensuring it is vertically aligned with the ground and forcefully inserted into the soil for initial positioning. Subsequently, the rotating ring 506 is manually rotated, causing the connecting rod 505 and the rotating block 504 to rotate, simultaneously moving the connecting plate 507. This, in turn, drives the positioning block 503 to move smoothly and unfold under the constraint of the moving hole 8, embedding it into the soil. This further reinforces the device and prevents the adjusting leg 4 from shifting during the inspection process. After fixing, the device enters the adjustment stage. The T-shaped block 205 is manually pressed, compressing the spring 204 to release the pressure. Locking the movable block 203 allows the cover plate 201 to move along the slide groove 9 under the constraint of the movable block 203. When it moves into place, the spring 204 rebounds and drives the T-shaped block 205 to reset and embed into the positioning hole 10 on the surface of the mounting frame 1 to complete the locking, realizing flexible adjustment of the height of the radar body 207. At the same time, with the angle adjustment function of the universal ball joint 206, the radar body 207 can be rotated to the required detection direction. Then, the level 11 is used for calibration to ensure that the radar body 207 can be accurately aligned with the detection target, ensuring the accuracy of the detection data. After the detection is completed, the rotating ring 506 is rotated in the opposite direction to drive the positioning block 503 to retract, releasing the lock of the fixing component 5. Then, the conical cylinder 502 is pulled out and the adjusting leg 4 is closed, so that the arc-shaped magnetic suction plates 13 come into contact with each other to complete the adsorption and fixation, which facilitates subsequent transportation.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
