Description

Technical Field

[0001] This utility model relates to the field of gas detector technology, and in particular to a binocular laser telemetry module. Background Technology

[0002] Currently, most laser gas detection modules on the market emit a fixed-wavelength laser with a specific signal from the transmitter. The laser shines on the target area and reflects back. A single receiver detects the signal change of the reflected light, thereby determining the gas concentration value in that area.

[0003] Existing monocular small telemetry modules have only one receiving end. When receiving reflected laser light, the light-receiving area is small, resulting in a weak light signal and causing a large error in the measured gas concentration. It also limits the test distance. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] See Figures 1-4 As shown, an embodiment of this utility model proposes a binocular laser telemetry module, which is part of a gas detector. It is used to realize the detection of emitted laser after reflection in the detection gas, and obtain the corresponding detection signal so as to obtain the concentration of the detection gas by combining with the calculation circuit in the gas detector. The principle and method of gas concentration detection are mature technologies. This embodiment mainly optimizes the weak light signal receiving area and the light focusing. Specifically, the entire module includes a main body 1, which has a first mounting hole 2 and two second mounting holes 3 located on either side of the first mounting hole 2. The second mounting holes 3 are inverted conical holes. A receiver 4 is installed at the smaller end of the second mounting hole 3, and a focusing component 5 is installed at the larger end of the second mounting hole 3. A laser emitter 6 is installed inside the first mounting hole 2. By setting one first mounting hole 2 and two second mounting holes 3 on either side of it, two sets of focusing components 5 and receivers 4 are integrated on both sides of a laser emitter 6, forming a "one emitter, two receivers" structure. The laser emitted by the laser emitter 6 is reflected in the detection gas and received by the two receivers 4. The focusing component 5 enables the weak light signal to be received over a large area and can focus the light to enhance the intensity of the light signal, thereby improving the detection sensitivity of the receivers 4. At the same time, the highly integrated structure achieves a very small overall size of the module. In addition, a cover 7 is detachably installed on the main body 1. The cover 7 is used to cover the receivers 4 and the laser emitter 6, and the cover 7 is set to protect the internal components.

[0026] The second mounting hole 3 has a tapered hole structure, which can maximize the area of ​​the light-concentrating component 5 and increase the light-receiving area. At the same time, the light signal emitted towards the receiver 4 after focusing is superimposed, and the receiver 4 can have better detection sensitivity.

[0027] Specifically, the focusing component 5 includes a first washer 51 embedded in the second mounting hole 3 and a lens 52 disposed above the first washer 51. The second mounting hole 3 is provided with a pressure ring 53 for pressing the lens 52. At the same time, the second mounting hole 3 is provided with a protective window 54 above the pressure ring 53 and a glass plate 55 above the protective window 54. The second mounting hole 3 is provided with a second washer 56 on the glass plate 55 and a locking ring 57 for pressing the second washer 56. Thus, the glass plate 55 is locked and pressed against the protective window 54 by the locking ring 57 and the second washer 56, thereby isolating the interior and allowing light to pass through. The lens 52 is used to focus the light, superimposing multiple weak beams of light and sending them to the receiver 4. The lens 52 is pressed by the pressure ring 53, and after the locking ring 57 is locked onto the main body 1, all internal optical elements are locked and limited, which can avoid shaking noise and ensure that the light path can reliably reach the receiver 4 after passing through the lens 52.

[0028] Thus, multiple beams of light enter through the focusing component 5 and are focused by the lens 52, thereby increasing the light intensity and improving the detection sensitivity of the receiver 4.

[0029] Meanwhile, in order to facilitate the identification of visible light to know the specific laser emission direction when the laser emission is detected, a third mounting hole 8 is provided on the main body 1 on one side of the first mounting hole 2. An indicator green light emitter 9 is installed in the third mounting hole 8. The green light emitted by the indicator green light emitter 9 coincides with the laser light path emitted by the laser emitter 6. Since the green light emitted by the indicator green light emitter 9 coincides with the emitted laser, the direction of the green light indicates the direction of the laser.

[0030] To facilitate the integration of internal components and ensure reliable installation of the cover 7 while providing spatial isolation between the two sets of receivers 4, a first step portion 101 and a second step portion 102 are provided on the main body 1 at intervals. The main body 1 also has a protrusion 103 located between the first step portion 101 and the second step portion 102. The cover 7 includes a first half-cover 71 and a second half-cover 72. The first half-cover 71 is installed on the first step portion 101, and the second half-cover 72 is installed on the second step portion 102. The protrusion 103 positions the mating part of the first half-cover 71 and the second half-cover 72. The first step portion 101 securely installs the first half-cover 71, and the second step portion 102 securely installs the second half-cover 72. This allows for independent assembly or maintenance of the components on both sides, and provides a certain degree of isolation through the middle part.

[0031] After the first half-cover 71 and the second half-cover 72 are securely installed, the main body 1, the first half-cover 71, and the second half-cover 72 enclose each other to form a first mounting groove 10. The first mounting groove 10 is provided with a stepped groove 11, and mounting posts 12 are provided at the corners of the main body 1, the first half-cover 71, and the second half-cover 72. The mounting posts 12 are provided with first fastening holes 13. The first mounting groove 10 is used to install the circuit board, which is supported by the mounting posts 12. The fasteners lock the circuit board in the first fastening holes 13. At the same time, the bottom cover of the circuit board can be installed by the adjustment groove, so as to facilitate the integration of the receiver 4 and the laser emitter 6 from the bottom position onto the circuit board and form internal protection.

[0032] Meanwhile, in order to facilitate the positioning and installation of the receiver 4, a first stepped hole 14 is provided at the bottom of the second mounting hole 3. The receiver 4 is installed on the first stepped hole 14, and the positioning of the receiver 4 is achieved through the first stepped hole 14.

[0033] The laser emitter 6 also needs to be positioned. The main body 1 is provided with an embedding groove 15 that connects to the first mounting hole 2. The bottom of the first mounting hole 2 is provided with a second stepped hole 16. The laser emitter 6 is installed in the embedding groove 15. The light-emitting end of the laser emitter 6 extends into the second stepped hole 16. After the laser emitter 6 is installed in the embedding groove 15, the light-emitting end is limited by the second stepped hole 16, which can prevent light leakage at the installation point.

[0034] Therefore, by reliably installing receiver 4 and laser transmitter 6, there will be no swaying during actual use, ensuring the consistency of the optical path and avoiding abnormal noise.

[0035] To facilitate integration into a gas detector, the entire module is provided with a second mounting groove 17 on the main body 1, away from the first step portion 101. The second mounting groove 17 is provided with four mounting blocks 18 spaced apart. Each mounting block 18 is provided with a second fastening hole 19. The second mounting groove 17 is used to achieve installation and positioning. After the internal mounting blocks 18 form a secondary positioning, the fasteners are locked to the second fastening holes 19 to achieve the installation of the entire module.
