Description
Technical Field
[0001] This utility model belongs to the field of searchlight technology, and in particular relates to a searchlight for underground maintenance and inspection. Background Technology
[0002] Downhole maintenance and inspection is a process of regularly and systematically checking downhole equipment, environment, and safety parameters. Its core purpose is to prevent accidents by proactively identifying potential hazards. Searchlights, as a key tool, provide high-intensity, long-distance, and explosion-proof lighting, solving the problem of visual obstacles in the dimly lit environment of the mine. This ensures that inspection personnel can clearly observe the equipment status and identify hazards, thereby ensuring operational safety and efficiency. In current downhole maintenance operations, searchlights are often provided on-site, and maintenance can be carried out simply by turning on the searchlights.
[0003] Chinese Patent Publication No. 202320694569.7 discloses an underground inspection and maintenance searchlight, relating to the field of searchlight technology. This underground inspection and maintenance searchlight includes a lamp body and a support frame installed at the lower end of the lamp body for support. The support frame is movably mounted on the lower surface of the lamp body. Auxiliary lighting units are arranged on both sides of the lamp body. After the lamp body is positioned as needed, the support frame corresponding to the lower end is rotated out according to the required lighting angle. The support frame can support the upper support rod, thereby fixing the lamp body at a suitable angle for convenient lighting operations. If the support angle needs to be adjusted, the adjusting threaded ring can be rotated to extend the internal second rod, allowing for the extension of the support rod and facilitating adjustment of the lamp body's tilt angle.
[0004] However, existing downhole searchlights have many technical shortcomings: Firstly, the fixed installation structure of the signal device makes it impossible to flexibly adjust the installation angle according to different inspection locations and signal coverage requirements underground, resulting in poor signal transmission and reception stability and easy signal blind spots. Secondly, the connection structure of the searchlight components is poorly designed and lacks a reliable positioning and locking mechanism. In the bumpy and vibrating environment underground, it is prone to loosening and displacement, which not only affects the normal operation of the signal device, but may also cause the components to fall off and cause safety hazards. Third, the component assembly process is cumbersome, lacks a quick pre-positioning structure, requires the use of multiple tools to complete the installation, and has poor operational convenience in the confined space of the well. In addition, the existing structure does not fully consider the installation and maintenance needs of the confined space downhole. The compact layout of components results in insufficient operating space for subsequent maintenance and angle adjustment, which significantly reduces operational efficiency.
[0005] In summary, there is an urgent need to develop a searchlight for underground maintenance and inspection that is flexible, stable, easy to assemble, and can ensure the stable operation of the signal device, in order to overcome the shortcomings of existing technologies. Utility Model Content

[0023] like Figures 1-5 As shown, a searchlight for underground maintenance and inspection includes: Lamp body 100; A fixing post 120 is set on the top of the lamp body 100. Its side wall has a mounting hole 121 and a positioning hole 122. The mounting hole 121 penetrates the side wall of the fixing post 120, and the positioning hole 122 communicates with the mounting hole 121. The mounting compartment 150 is used to install a signal device to enable the signal transmission of the searchlight. A rotating rod 140 is fixedly installed on its side wall. The rotating rod 140 is rotatably installed in the mounting hole 121. Specifically, the mounting compartment 150 has an arc-shaped structure, which can reduce problems such as rainwater accumulation, animal nesting and gnawing, and debris residue. The signal device is used to receive or send a trigger signal to trigger the lamp body 100, thereby enabling the lamp body 100 to be turned on or off. The connecting column 130 is located on top of the fixed column 120, and a protruding shaft 131 is provided on the upper end of its side wall; A fixing rod 200 is set above the lamp body 100, and a mounting shell 210 is fixedly set at its bottom end. The bottom of the mounting shell 210 is provided with a through groove 220 that is adapted to the convex shaft 131. The mounting component is located on one side of the fixed column 120 and is used to fix the positions of the mounting chamber 150, the mounting shell 210 and the connecting column 130.
[0024] This application allows for flexible adjustment of the angle of the mounting chamber 150 of the built-in signaler through the rotational engagement of the rotating rod 140 and the mounting hole 121, adapting to the signal transmission and reception needs of different inspection locations downhole. The matching design of the convex shaft 131 and the through groove 220 provides a quick positioning and assembly basis for the fixed rod 200 and the connecting column 130. The mounting components ensure the stable locking of the mounting chamber 150, the mounting shell 210, and the connecting column 130, preventing downhole bumps and vibrations from causing the components to loosen, ensuring the stable operation of the signaler and the overall structural reliability of the searchlight. At the same time, the modular design of each component facilitates on-site installation and maintenance downhole.
[0025] In the example of this application, a positioning groove 141 is provided in the middle of the side wall of the rotating rod 140, and the positioning groove 141 is distributed along the circumference of the rotating rod 140.
[0026] As a preferred example of this utility model, the circumferentially distributed positioning grooves 141 provide a full-angle positioning reference for the rotating rod 140, enabling the rotating rod 140 to cooperate with the installation components at any adjustable angle to achieve angle locking of the installation chamber 150. This avoids the angle deviation of the installation chamber 150 caused by equipment vibration during underground inspection, ensuring that the signal receiver is always at the preset signal transmission and reception angle, improving signal transmission stability, and enhancing the controllability and accuracy of rotation adjustment.
[0027] In the example of this application, the side wall of the connecting post 130 is provided with a screw hole 132.
[0028] As a preferred example of this utility model, the screw hole 132 provides a standardized threaded connection point for the mounting component, making the connection between the mounting component and the connecting post 130 more stable and detachable. Compared with other connection methods, the threaded connection has good vibration resistance and is suitable for the complex bumpy environment downhole. At the same time, it provides a unified connection benchmark for the subsequent fixing of the mounting shell 210 and the connecting post 130, ensuring the consistency and compatibility of multi-component assembly and facilitating component replacement and maintenance.
[0029] In the example of this application, the mounting component includes a mounting plate 160, and a first screw 161 is threadedly connected to the lower end of the side wall of the mounting plate 160. The first screw 161 is adapted to the positioning hole 122. Specifically, an anti-slip layer is provided on the outer side of the positioning groove 141, and the anti-slip layer is made of rubber.
[0030] As a preferred example of this utility model, the matching and cooperation between the first screw 161 and the positioning hole 122 and the positioning groove 141 can realize the positioning and locking of the rotating rod 140, and directly fix the adjustment angle of the installation chamber 150. The design of the anti-slip layer increases the contact friction between the first screw 161 and the positioning groove 141, further improving the locking stability and preventing the screw from loosening and the angle of the installation chamber 150 from shifting due to downhole vibration.
[0031] In the example of this application, a second screw 162 is rotatably provided on the upper side wall of the mounting plate 160, and the second screw 162 is adapted to the screw hole 132.
[0032] As a preferred example of this utility model, the rotatable second screw 162 is adapted to the screw hole 132 to achieve a stable connection between the upper end of the mounting plate 160 and the connecting column 130. Together with the lower first screw 161, it forms a two-point fixing structure, which improves the fixing reliability of the mounting plate 160. The rotation setting allows the second screw 162 to be flexibly adjusted to adjust the screwing depth to adapt to different assembly gap requirements. At the same time, it facilitates installation and disassembly, reduces the operational difficulty of on-site maintenance in the well, and ensures the stable constraint effect of the installation components on each core component.
[0033] In the example of this application, the side wall of the mounting housing 210 is provided with a connection hole 230 that is adapted to the screw hole 132.
[0034] As a preferred example of this utility model, the matching of the connecting hole 230 and the screw hole 132 allows the mounting shell 210 and the connecting column 130 to be positioned and securely connected by fasteners (such as bolts), preventing relative shaking between the mounting shell 210 and the connecting column 130, ensuring the integrity of the connection between the fixing rod 200 and the lamp body 100, preventing the fixing rod 200 from loosening and falling off due to downhole vibration, and providing a co-fixing point for the mounting components, further enhancing the stability of the overall structure.
[0035] In the example of this application, the through groove 220 is L-shaped and is adapted to the convex shaft 131.
[0036] As a preferred example of this utility model, the L-shaped through groove 220 and the convex shaft 131 are adapted to achieve quick pre-fixation of the mounting shell 210 and the connecting column 130. The convex shaft 131 can be inserted along the straight section of the through groove 220 and then rotated into the transverse section to complete the limiting. Preliminary positioning can be achieved without the aid of tools, which simplifies the installation process and improves the efficiency of on-site assembly in the well. At the same time, the L-shaped structure can effectively prevent the convex shaft 131 from accidentally coming out, ensuring the safety of the connection.
[0037] In the example of this application, a connector 151 is fixedly connected to the lower end of the side wall of the installation compartment 150.
[0038] As a preferred example of this utility model, the fixed configuration of the connector 151 provides a standardized wiring interface for the signal device inside the installation compartment 150, facilitating the connection between the signal device and the power supply line of the lamp body 100 or the external communication line. The fixed connection of the connector 151 can prevent the connection from becoming loose or falling off due to pulling the line underground, ensuring the stability of signal transmission and power supply. At the same time, the standardized interface reduces the difficulty of wiring connection and facilitates the inspection and maintenance of the line during the inspection process. The underground signal device generates a preset signal (sound / light / electric signal) through the core circuit (such as oscillation circuit, amplification circuit), which is transmitted to the receiving end through the transmission module (wired cable or wireless radio frequency) to complete the functions of inspection positioning, alarm, communication, etc. It is suitable for the explosive environment and complex working conditions underground. It is a well-known technology and will not be described in detail here.
[0039] In the example of this application, the axes of the mounting hole 121 and the positioning hole 122 are perpendicular to each other.
[0040] As a preferred example of this utility model, the design of the mounting hole 121 being perpendicular to the axis of the positioning hole 122 ensures that the locking force of the first screw 161 on the rotating rod 140 is perpendicular to the axis of the rotating rod 140, forming an efficient radial positioning constraint and improving the stability of positioning and locking. Simultaneously, the vertical layout makes reasonable use of the internal space of the fixing column 120, avoids interference between the two holes, makes the structure of the fixing column 120 more compact, adapts to the limited installation space downhole, and facilitates processing and manufacturing.
[0041] In the example of this application, an extension rod 110 is fixedly connected to the top of the lamp body 100, and a fixing post 120 is fixedly connected to the top of the extension rod 110.
[0042] As a preferred example of this utility model, the extension rod 110 raises the installation height of the fixing column 120 and subsequent components, preventing the heat generated by the lamp body 100 during operation from being directly transferred to the signal device inside the installation chamber 150, thus ensuring the signal device operates stably at a suitable temperature. Simultaneously, the increased installation height provides ample operating space for the assembly and adjustment of the installation chamber 150 and installation components, facilitating component installation, angle adjustment, and maintenance by downhole inspection personnel, thereby improving operational convenience.
[0043] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
