Description

Technical Field

[0001] The utility model relates to the technical field of urban geological exploration, in particular to a detector dragging device used for urban hard road surface wave exploration. Background Art

[0002] In existing urban pavement surface wave exploration technologies, traditional geophones often use metal conical bases or circular metal bases. While these designs can effectively stabilize in soft soil layers, they can easily cause geophone instability when used on hard pavement, thus affecting the accurate acquisition of surface wave signals. Geophones with traditional metal conical base designs are mainly suitable for soft soil layers and cannot be used on urban hard pavement. While the circular metal base design of ordinary circular metal base geophones allows the geophone to be stably placed on hard pavement, it cannot be moved freely and requires manual position adjustment, resulting in low work efficiency. Furthermore, while existing technologies can achieve the movement of geophones by connecting multiple geophones in series using nylon straps, contact between the nylon straps and the geophones can cause signal interference, affecting the accuracy of surface wave signal acquisition. Utility Model Content

[0003] The utility model provides a detector dragging device for urban hard road surface wave exploration, in particular a detector placement and dragging device for urban hard road surface wave exploration, which can improve the stability and mobility of the detector on the hard road surface, and ensure the accuracy of the exploration data and the convenience of operation.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A detector dragging device for urban hard road surface wave exploration, comprising:

[0006] A geophone tray, comprising an outer cylinder and an inner cylinder coaxially arranged inside the outer cylinder, wherein a bottom support for placing the geophone is provided inside the inner cylinder; and

[0007] A dragging assembly is arranged on the outer wall of the bottom end of the detector tray. The dragging assembly includes a passing block fixed on the side wall of the detector tray and a locking member arranged on the passing block.

[0008] Preferably, a receiving groove is formed between the inner wall of the outer cylinder and the outer wall of the inner cylinder.

[0009] Preferably, the top side wall of the outer cylinder is provided with a locking screw distributed radially along the outer cylinder, the locking screw is arranged through the outer cylinder, and one end of the locking screw placed inside the outer cylinder can be against the outer wall of the inner cylinder.

[0010] Preferably, an inverted trapezoidal notch is provided at the bottom of the inner cylinder.

[0011] Preferably, the base includes an inverted trapezoidal connecting column matched with the inverted trapezoidal notch and a supporting plate arranged on the top of the inverted trapezoidal connecting column.

[0012] Preferably, a threaded barrel for connecting to the detector is provided on the top of the support plate.

[0013] Preferably, the passing block is a square block with a passing hole provided inside.

[0014] Preferably, the locking member is a fastening stud threadedly arranged on the side wall of the square block.

[0015] Preferably, the dragging assembly further includes a dragging rope arranged inside the traveling block.

[0016] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0017] 1. In the present invention, the geophone is fixed to the base, ensuring the base is stable and the geophone is fixed. The combined unit is then placed in the inner cavity of the inner cylinder for fixation, ensuring stability on hard surfaces without tilting. At the same time, the base can effectively withstand the vibration transmission of surface wave signals and maintain stability. After the geophone is installed, one end of the tow rope can be passed through the pass-through block and the tow rope placed in the pass-through block is fixed to ensure that the tow rope is secure and not loose. In addition, the length of the tow rope can be adjusted according to the size of the exploration area. The base design of the present application can effectively maintain the stability of the geophone on hard surfaces, preventing tilting or tipping, and ensuring the acquisition of accurate surface wave signals. The tow rope is fixed by the tow assembly design, which facilitates the connection of multiple geophones in series and allows them to move freely within the exploration area, reducing the workload of manually adjusting the geophone position. Unlike the traditional nylon belt connection method, the design of the geophone tray avoids direct contact between the nylon belt and the geophone, thereby reducing friction and signal interference, and ensuring the accuracy of the acquired signal.

[0018] 2. In the present invention, the geophone tray and the base work together: the inner cylinder of the geophone tray is provided with an inverted trapezoidal notch, and the bottom of the base is provided with an inverted trapezoidal connecting column. This allows the geophone to maintain a stable position during movement on hard roads, avoiding the problem of geophone tilting or instability, and can significantly improve the operational efficiency during surface wave exploration. Compared with traditional circular or conical bases, this design is more adaptable to hard roads, prevents the geophone from tilting or tipping, and improves the accuracy of signal acquisition.

[0019] 3. In the present invention, the drag rope fixation is adjustable: the pass-through block design of the detector tray can accommodate the drag rope and fix it by screwing it, ensuring that the drag rope is firm and not loose. By adjusting the number and length of the drag ropes, the movement path of the detector can be flexibly adjusted to adapt to exploration areas of different sizes.

[0020] 4. In this utility model, the innovative design of the cable storage groove: the storage groove is set in the detector tray, which can effectively organize the cables and prevent the cables from getting knotted or entangled during movement. The cables are fixed by the locking screw, which not only reduces the trouble during operation, but also avoids the signal loss problem caused by loose cables.

[0021] 5. In the present invention, the convenience of connecting multiple detectors in series: multiple detector trays can be connected in series through a drag rope, so that multiple detectors can move continuously in the same direction, improving the efficiency of surface wave exploration, especially in large-scale exploration areas, avoiding the problem of frequent position adjustment of a single detector.

[0022] 6. In this utility model, the design to prevent signal interference: Compared with the traditional nylon belt series connection method, the provision of a detector tray avoids contact between the belt and the detector, thereby reducing signal interference caused by friction. This design ensures that the signals collected during the exploration process are more accurate and avoids the noise impact caused by friction.

[0023] 7. The present invention is specially designed to adapt to the special requirements of urban hard roads: The present invention takes into special consideration the special requirements of urban hard roads, and adopts a design that can be stably fixed, easy to move, and does not interfere with the collected signals. It breaks through the limitation that traditional equipment cannot be effectively stabilized and moved on hard roads, and provides a more efficient and accurate exploration tool.

DETAILED DESCRIPTION

[0032] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] In order to achieve the above purpose, the embodiment of the present utility model adopts the following technical solutions: Figure 1 、 Figure 2 、 Figure 3 , a detector dragging device for urban hard road surface wave exploration, including a detector tray 10 and a dragging assembly. Further, the detector tray includes an outer cylinder 110 and an inner cylinder 120, and the inner cylinder 120 is coaxially arranged on the inner side of the outer cylinder. At the same time, a base 130 for placing the detector is provided inside the inner cylinder 120. The dragging assembly is arranged on the outer wall of the bottom end of the detector tray 10, and the dragging assembly includes a passing block 210 and a locking piece. The passing block 210 is fixedly arranged on the side wall of the detector tray, and the locking piece is arranged on the passing block for fixing the drag rope for dragging the detector tray. When in use, the detector 40 is fixed on the base to ensure that the base is stable and the detector is fixed, and then the combination is placed in the inner cavity of the inner cylinder for fixation, so as to achieve stability and no tilting on the hard road surface. The base support is tilted, and at the same time, the base support can effectively withstand the vibration transmission of the surface wave signal and maintain stability. After the detector is installed, one end of the drag rope can be passed through the through-block, and the drag rope placed in the through-block can be fixed to ensure that the drag rope is firm and not loose. In addition, the length of the drag rope can be adjusted according to the size of the exploration area. The base support design in this application can effectively keep the detector stable on the hard road surface, avoid tilting or tipping, and ensure the collection of accurate surface wave signals; the drag rope is fixed by the drag assembly design, which can facilitate the connection of multiple detectors in series and make them move freely in the exploration area, reducing the workload of manually adjusting the position of the detector; different from the traditional nylon belt series connection method, the design of the detector tray avoids direct contact between the nylon belt and the detector, thereby reducing friction and signal interference, and ensuring the accuracy of the collected signal.

[0034] It should be noted that the detector tray 10 is made of polylactic acid, which has good biodegradability and biocompatibility. At the same time, the circular base design of the detector tray ensures that the detector remains stable during movement and avoids tipping over.

[0035] As a preferred technical solution of this embodiment, a storage groove 140 is formed between the inner wall of the outer cylinder 110 and the outer wall of the inner cylinder 120. The storage groove is used to organize and store the detector cable to avoid cable entanglement. That is, during the specific working process, the detector cable can be led out and wrapped around the outer wall of the inner cylinder to achieve effective cable organization.

[0036] Furthermore, a locking screw 30 is provided on the top side wall of the outer cylinder 110, and the locking screw 30 is distributed along the radial direction of the outer cylinder. Specifically, the locking screw is threaded through the outer cylinder, and one end of the locking screw 30 placed inside the outer cylinder 110 can be against the outer wall of the inner cylinder 120. When in use, after the detector cable is wrapped around the outer wall of the inner cylinder, the locking screw can be driven to screw toward the inner cylinder. When the inner end of the locking screw contacts the cable, the detector cable can be fixed to ensure that the cable is neat and will not be pulled by external forces.

[0037] Reference Figure 3 、 Figure 4 、 Figure 5 In some embodiments, the bottom of the inner cylinder 120 is provided with an inverted trapezoidal notch 121. Accordingly, the base 130 includes an inverted trapezoidal connecting post 131 and a supporting plate 132. The inverted trapezoidal connecting post 131 cooperates with the inverted trapezoidal notch 121, and the supporting plate 132 is fixedly mounted on top of the inverted trapezoidal connecting post. During use, the geophone is fixedly mounted on top of the supporting plate, and the inverted trapezoidal connecting post and the supporting plate are then placed integrally within the inverted trapezoidal notch of the inner cylinder. The inverted trapezoidal notch of the inner cylinder and the inverted trapezoidal connecting post cooperate to securely accommodate the base. It should be noted that the base is made of metal, which can effectively withstand the vibration transmission of surface wave signals and maintain stability.

[0038] Reference Figure 6 Furthermore, in order to achieve a stable connection between the detector and the support plate, a threaded barrel 133 for connecting to the detector is provided on the top of the support plate 132. Correspondingly, a threaded column is provided at the bottom of the detector. When in use, the threaded connection between the threaded column and the threaded barrel can be utilized to obtain a fixed connection between the detector and the support plate.

[0039] Reference Figure 7In some embodiments, the passage block 210 is a square block with a passage hole defined therein, and the locking member is a fastening stud 220 threadedly mounted on the side wall of the square block. Furthermore, the drag assembly also includes a drag rope 230 disposed within the passage block 210. During use, after the drag rope passes through the passage hole, the operator secures the drag rope by tightening the fastening stud, and then pulls the drag rope to move the geophone tray. Furthermore, multiple geophone trays can be connected in series using the drag rope to ensure smooth movement of the geophones in the same direction. Specifically, the operator can pull the drag rope to freely move all the connected geophone trays on the road surface, completing the acquisition of surface wave signals.
