Description

Technical Field

[0001] This utility model relates to the field of detector technology, and in particular to a lead selenide detector with an independent heat dissipation structure. Background Technology

[0002] Lead selenide detectors possess unique advantages in the field of infrared detection. Due to their high sensitivity, fast response, wide detection range, and high stability, they are widely used in various fields such as security monitoring, industrial automation, environmental monitoring, and medical imaging. However, lead selenide detectors generate heat during operation, especially under high-sensitivity and high-response-speed conditions. If this heat cannot be dissipated in time, the detector temperature will rise, affecting its performance, such as decreased sensitivity and slower response speed. Therefore, it is necessary to design a lead selenide detector with an independent heat dissipation structure.

[0003] To address this, patent CN222071954U discloses a lead selenide detector with a retractable probe, comprising a detector body, a connecting sleeve at the upper end of the detector body, a connecting post inside the connecting sleeve, a mounting plate fixedly connected to the upper end of the connecting post, a fixed inner core at the upper center of the mounting plate, and an adjusting screw on the outer surface of the fixed inner core. The adjusting screw is rotatably connected to the mounting plate via a rotating disk. This invention, by rotating the rotating disk, drives the adjusting screw to rotate, thereby causing the movable sleeve to move along the axis of the adjusting screw. Controlling the movable sleeve to move upwards can drive the movable probe to move upwards, thus achieving the purpose of adjusting the length of the detector probe. At the same time, through a unique structural design, it can be ensured that the telescopic component acting on the detector probe will not have any electrical contact with the fixed inner core, the connecting block, or the movable probe, avoiding the telescopic component affecting the signal transmission of the detector probe.

[0004] Although the probe of the lead selenide detector mentioned above can be extended or retracted during use, the probe is easily damaged and difficult to replace during long-term use. Therefore, it is necessary to design a lead selenide detector with an independent heat dissipation structure. Utility Model Content

[0005] The purpose of this invention is to provide a lead selenide detector with an independent heat dissipation structure to solve the defects of existing lead selenide detector probes that are easily damaged and difficult to replace during long-term use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lead selenide detector with an independent heat dissipation structure, including a detector body;

[0007] Heat dissipation mechanisms are fixed on the outer walls of both sides of the detector body, and a mounting plate is fixed on the bottom of the detector body.

[0008] The mounting plate has a support plate fixed to its bottom end, and the support plate has a disassembly structure fixed to both sides of its bottom end. The disassembly structure includes a disassembly seat fixed to both sides of the support plate bottom end, and the bottom of the disassembly seat is engaged with a connecting block. The two sides inside the disassembly seat are threaded with fixing bolts.

[0009] Each of the connecting blocks has a probe fixed to its bottom end.

[0010] Furthermore, the heat dissipation mechanism includes an adhesive layer, a heat-conducting plate, and heat dissipation fins. The adhesive layer is fixed to the outer wall on both sides of the detector body, and a heat-conducting plate is fixed to the outer wall of the adhesive layer. Heat dissipation fins are uniformly fixed to the outer wall of the heat-conducting plate.

[0011] Furthermore, the heat-conducting plates are symmetrically distributed on both sides of the detector body.

[0012] Furthermore, the heat dissipation fins are evenly distributed on the outer wall of the heat-conducting plate.

[0013] Furthermore, the mounting and disassembly bases are symmetrically distributed on both sides of the support plate.

[0014] Furthermore, one end of each fixing bolt extends into the interior of the connecting block.

[0015] Furthermore, the fixing bolts are symmetrically distributed on both sides of the mounting and dismounting base.

[0016] The lead selenide detector with an independent heat dissipation structure provided by this utility model has the following advantages:

[0017] With a disassembly and assembly structure, the connecting block and the disassembly and assembly base can be easily fixed together by the connection of the fixing bolt. The probe can be installed and disassembled through the connecting block, which realizes that the device has the function of easy installation and disassembly of the probe and improves the convenience of the lead selenide detector in use.

[0018] By incorporating a heat dissipation mechanism, the heat generated by the internal components of the detector body during operation can be easily transferred to the heat dissipation fins through the heat conduction of the heat-conducting plate. The uniform distribution of the heat dissipation fins facilitates the even dissipation of heat into the air, enabling the detector body to dissipate heat autonomously during use. This achieves the function of autonomous heat dissipation, improving the heat dissipation efficiency and working efficiency of the lead selenide detector during use. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-5 The present invention provides a lead selenide detector with an independent heat dissipation structure, including a detector body 1.

[0027] Reference Figures 1-5 Heat dissipation mechanisms 2 are fixed on the outer walls of both sides of the detector body 1. The heat dissipation mechanism 2 includes an adhesive layer 21, a heat-conducting plate 22, and heat dissipation fins 23. The adhesive layer 21 is fixed on the outer walls of both sides of the detector body 1. The heat-conducting plate 22 is fixed on the outer wall of the adhesive layer 21. Heat dissipation fins 23 are evenly fixed on the outer wall of the heat-conducting plate 22. The heat-conducting plate 22 is symmetrically distributed on both sides of the detector body 1. The heat dissipation fins 23 are evenly distributed on the outer wall of the heat-conducting plate 22. The bottom end of the detector body 1 is fixed with a mounting plate 3.

[0028] The heat generated by the internal components of the detector body 1 during operation can be transferred to the heat dissipation fins 23 through the heat conduction plate 22. Under the uniform distribution of the heat dissipation fins 23, the heat can be evenly dissipated into the air, which facilitates the detector body 1 to dissipate heat independently during use.

[0029] Reference Figure 1 , Figure 3 and Figure 4A support plate 4 is fixed to the bottom of the mounting plate 3. A disassembly structure 5 is fixed to both sides of the bottom of the support plate 4. The disassembly structure 5 includes a disassembly seat 51 fixed to both sides of the bottom of the support plate 4. A connecting block 52 is engaged at the bottom of each disassembly seat 51. A fixing bolt 53 is threaded to both sides inside the disassembly seat 51. A probe 6 is fixed to the bottom of each connecting block 52. The disassembly seats 51 are symmetrically distributed on both sides of the support plate 4. One end of each fixing bolt 53 extends into the interior of the connecting block 52. The fixing bolts 53 are symmetrically distributed on both sides of the disassembly seat 51.

[0030] When installing the probe 6, insert the connecting block 52 at the top of the probe 6 into the reserved groove at the bottom of the mounting base 51, and then insert the fixing bolt 53 into both sides of the mounting base 51. Rotate the fixing bolt 53 so that the fixing bolt 53 continues to extend into the interior of the connecting block 52, thereby fixing the connecting block 52 and the mounting base 51 together. This makes it easier to install the probe 6 at the bottom of the support plate 4.
