Description

Technical Field

[0001] The invention relates to the technical field of protective shells, and in particular to an infrared thermal imaging detector protective shell with an under-net brush structure. Background Art

[0002] Infrared thermal imaging detectors are widely used in military, firefighting, industrial inspection, medical and other fields. In the field of firefighting, infrared thermal imaging detectors are usually used on water cannons to monitor temperature changes in the area. When abnormal temperatures in nearby areas are detected, water cannons are immediately driven to spray high-pressure water to the abnormal temperature area to eliminate potential dangers. Since the application environment of water cannons is very different, in order to protect infrared thermal imaging detectors from the influence of these environmental factors and ensure their long-term stable operation, they are usually equipped with protective shells.

[0003] Existing protective shells usually simply cover the infrared imaging detector. In order to ensure that the detector can monitor the external environment in real time, the detector is usually covered with a glass plate. However, since the water monitor is in an inactive state in most cases, as the "standby" time increases, dust will gradually accumulate on the outside of the glass plate, thereby blocking the infrared imaging detector and affecting its normal monitoring of the outside world. This may cause the water monitor to fail to start in the first place, seriously threatening the safety in the area. Summary of the invention

DETAILED DESCRIPTION

[0024] Although the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention, it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.

[0025] like Figure 1-Figure 3 and Figure 7 As shown in the figure, an embodiment of the present invention is proposed, which provides an infrared thermal imaging detector protective shell with a brush-type structure under a net, so as to solve the problem that the existing protective shell cannot clean the glass cover after adding a protective net, resulting in poor infrared detection thermal imaging, including: a base shell 1; a cover plate 201, which is installed on the base shell 1; infrared glass 202 and ultraviolet glass 203, which are both installed on the cover plate 201, and the areas where the infrared glass 202 and the ultraviolet glass 203 contact the cover plate 201 are both stepped, which is used to keep the infrared glass 202 and the ultraviolet glass 203 and the base shell 1 stable; a protective net 204, which is installed on the cover plate 201; a rotating column 3, which is rotatably connected to the cover plate 201; a locking nut 4, which is threadedly connected to the rotating column 3; a mounting member 5, which is installed on the rotating column 3, and the locking nut 4 is used to fix the mounting member 5 Fixed; the cleaning piece 6 is installed on the mounting piece 5, the mounting piece 5 is made of elastic material, and an opening is provided on the side of the mounting piece 5 away from the rotating column 3 for replacing and installing the cleaning piece 6, the cleaning piece 6 is made of hard rubber material, and the side of the cleaning piece 6 close to the cover plate 201 is an arc-shaped surface, which is used to change the contact state between the cleaning piece 6 and the cover plate 201, the infrared glass 202 and the ultraviolet glass 203. The cleaning piece 6 is in contact with the cover plate 201, the infrared glass 202 and the ultraviolet glass 203. The length of the cleaning piece 6 is greater than the maximum distance from the edge of the infrared glass 202 and the ultraviolet glass 203 to the maximum distance from the edge of the infrared glass 202 and the ultraviolet glass 203 to the rotation center between the rotating column 3 and the cover plate 201, and the cleaning piece 6 is located between the cover plate 201 and the protective net 204; a power mechanism is arranged in the base shell 1, and is used to make the rotating column 3 and the cover plate 201 rotate relative to each other.

[0026] In the above scheme, the contact surface between the base shell 1 and the cover plate 201 is an explosion-proof joint surface, and a protective space is formed between the base shell 1 and the cover plate 201 to protect the electronic components therein. A sealing ring is provided between the base shell 1 and the cover plate 201 to isolate the external environment. The infrared glass 202 and the ultraviolet glass 203 are both sealed with the cover plate 201 by epoxy resin. The contact area between the infrared glass 202 and the ultraviolet glass 203 and the cover plate 201 can also be wedge-shaped to make the infrared glass 202 and the ultraviolet glass 203 The protective net 204 is made of steel and is used to protect the infrared glass 202 and the ultraviolet glass 203 to prevent the impact of foreign objects. The front side of the cleaning member 6 is an arc surface. During the use of the present invention, the present invention continues to protect the electronic components (including but not limited to infrared temperature sensors and ultraviolet glass tube sensors) therein. As the use time increases, dust will accumulate on the outside of the infrared glass 202 and the ultraviolet glass 203, and then the power mechanism is used to rotate the rotating column 3 counterclockwise (such as Figure 2 Taking the left viewing direction as an example, the rotating column 3 drives the mounting part 5 to rotate counterclockwise, and the mounting part 5 drives the cleaning part 6 to rotate counterclockwise, and the cleaning part 6 cleans the outside of the infrared glass 202 and the ultraviolet glass 203 to remove the dust accumulated on the outside of the two, so as to prevent the dust from blocking the detection heads of the infrared temperature sensor and the ultraviolet glass tube sensor, thereby causing errors in the detection of external conditions and affecting the normal detection work.

[0027] During the counterclockwise rotation of the cleaning piece 6, since the front side of the cleaning piece 6 is an arc-shaped surface, that is, during the counterclockwise rotation of the cleaning piece 6, the edge of the cleaning piece 6 in contact with the cover plate 201 will bend slightly backwards, thereby increasing the force applied by the cleaning piece 6 on the cover plate 201, the infrared glass 202 and the ultraviolet glass 203, thereby improving the cleaning effect, and then the power mechanism is used to rotate the rotating column 3 and the parts thereon clockwise (reset), and then the cleaning piece 6 will continue to bend toward the side of its arc-shaped surface, thereby reducing the resistance encountered by the cleaning piece 6 during the resetting process and reducing the loss of the cleaning piece 6, thereby extending the service life while ensuring the cleaning effect on the infrared glass 202 and the ultraviolet glass 203.

[0028] like Figure 3 , Figure 4 and Figure 7As shown, the power mechanism includes: a motor 701, installed on the base shell 1; a rotating member 702, arranged on the rotating column 3, and the rotating member 702 is rotatably connected to the cover plate 201; a bevel gear set 703, arranged between the output shaft of the motor 701 and the rotating member 702, the bevel gear set 703 is composed of a first bevel gear 7031 and a second bevel gear arranged in a mirror image, the second bevel gear 7032 is meshed with the first bevel gear 7031, the first bevel gear 7031 is a missing gear, the first bevel gear 7031 is fixedly connected to the output shaft of the motor 701, and the second bevel gear 7032 is fixedly connected to the rotating member 702.

[0029] In the above scheme, the first bevel gear 7031 rotates one circle, and the second bevel gear 7032 on the left side rotates 150° clockwise (such as Figure 4 The second bevel gear 7032 on the right side rotates counterclockwise by 150°, so that the area swept by the cleaning member 6 during the rotation completely covers the infrared glass 202 and the ultraviolet glass 203. When the infrared glass 202 and the ultraviolet glass 203 need to be cleaned, the first bevel gear 7031 is driven to rotate counterclockwise by the output shaft of the motor 701 (such as Figure 4 The first bevel gear 7031 meshes with the second bevel gear 7032 on the left side and drives it to rotate counterclockwise (such as the top view direction). Figure 4 (Taking the left viewing direction as an example), the second bevel gear 7032 on the left side drives the rotating member 702 to rotate counterclockwise, and the rotating member 702 drives the rotating column 3 to rotate counterclockwise, so that the cleaning member 6 rotates counterclockwise and cleans the infrared glass 202 and the ultraviolet glass 203. As the first bevel gear 7031 continues to rotate counterclockwise, when the first bevel gear 7031 rotates counterclockwise to disengage from the second bevel gear 7032 on the left side, the cleaning member 6 has completed the cleaning of the infrared glass 202 and the ultraviolet glass 203. Then the first bevel gear 7031 continues to rotate counterclockwise and meshes with the second bevel gear 7032 on the right side, and the second bevel gear 7032 on the right side starts to rotate clockwise, and the second bevel gear 7032 on the right side drives the rotating member 702 and the parts thereon to rotate clockwise, so that the cleaning member 6 rotates clockwise to reset.

[0030] like Figure 3-Figure 7 As shown, it also includes: a rotating shaft 801, which is rotatably connected to the mounting member 5; a cleaning brush 802, which is fixedly connected to the rotating shaft 801, and the cleaning brush 802 is in contact with the cover plate 201, the infrared glass 202 and the ultraviolet glass 203; a connecting column 803, which is arranged on the rotating column 3, and the connecting column 803 is fixedly connected to the rotating shaft 801, and the protrusion and the groove are limited and matched.

[0031] In the above scheme, the cleaning brush 802 is always in contact with the cover plate 201. The cleaning brush 802 is provided with a plurality of hard bristles for cleaning the dust left on the outside of the infrared glass 202 and the ultraviolet glass 203. During the counterclockwise rotation of the rotating column 3, the rotating column 3 drives the cleaning brush 802 to rotate counterclockwise through the mounting member 5. During the process, the cleaning brush 802 removes impurities that are easy to clean (such as dust, etc.), and the cleaning member 6 removes impurities that are difficult to clean (such as adhesions, etc.). Then, during the process of the rotating column 3 driving the parts thereon to reset, the impurities scraped off by the cleaning member 6 will be left on the outside of the infrared glass 202 and the ultraviolet glass 203 after falling off, and then these remaining impurities are removed by the cleaning brush 802 during the reset process (since the adhesion impurities have been scraped off by the cleaning member 6, the subsequent cleaning difficulty is greatly reduced), thereby increasing the impurity removal rate and improving the cleaning effect.

[0032] like Figure 5-Figure 7 As shown, it also includes: two limiting rods 9 arranged in a mirror image, both fixedly connected to the rotating member 702, the eccentric part of the connecting column 803 close to the rotating shaft 801 is set as a convex rod, the limiting rod 9 is squeezed and matched with the convex rod on the connecting column 803, the cleaning brush 802 is in contact and matched with the cleaning member 6, the connecting column 803 is connected to the rotating column 3 for limiting rotation, the connecting column 803 is provided with a protrusion, the rotating column 3 is provided with a groove, the protrusion and the groove are limited and matched, the rotating member 702 is rotationally connected to the rotating column 3, and the width of the cleaning brush 802 is greater than the distance between the rotating shaft 801 and the arc surface on the cleaning member 6.

[0033] In the above scheme, the cleaning brush 802 is not in contact with the cleaning member 6 at the beginning. There is friction between the rotating column 3 and the cover plate 201 to ensure that the two remain relatively still when there is no external interference. There is friction between the rotating shaft 801 and the mounting member 5, which has the same purpose as above, and the friction between the rotating shaft 801 and the mounting member 5 is smaller than the friction between the rotating column 3 and the cover plate 201. The deflection angle of the protrusion in the groove is less than 180°. During the counterclockwise rotation of the rotating member 702, the rotating member 702 drives the two limit rods 9 to rotate counterclockwise together. The limit rod 9 on the left (such as Figure 6The convex rod on the connecting column 803 is squeezed (taking the direction shown as an example), and the connecting column 803 drives the rotating shaft 801 to rotate counterclockwise (rotate) through the convex rod thereon, and the rotating shaft 801 and the mounting member 5 rotate relative to each other, and the rotating shaft 801 drives the cleaning brush 802 to rotate counterclockwise together, and the cleaning brush 802 gradually breaks away from contact with the cover plate 201 and gradually contacts with the cleaning member 6, so as to clean the dust accumulated in the cleaning member 6, so as to ensure the subsequent cleaning effect of the cleaning member 6 on the infrared glass 202 and the ultraviolet glass 203. After the rotating shaft 801 rotates counterclockwise to the extreme position (rotation 135°), the rotating member 702 continues to rotate counterclockwise, and the connecting column 803 drives the cleaning brush 802 to rotate counterclockwise through the rotating shaft 801, and the cleaning member 6 cleans the infrared glass 202 and the ultraviolet glass 203.

[0034] During the clockwise rotation of the rotating member 702, the rotating member 702 drives the two limit rods 9 to rotate clockwise together. Figure 6 The convex rod on the connecting column 803 is squeezed, and the connecting column 803 drives the rotating shaft 801 to rotate clockwise (rotate) through the convex rod thereon. The rotating shaft 801 and the mounting member 5 rotate relative to each other, and the rotating shaft 801 drives the cleaning brush 802 to rotate clockwise together. The cleaning brush 802 gradually contacts the cover plate 201 and cleans the impurities accumulated on the cleaning member 6 due to scraping, thereby ensuring the subsequent cleaning effect of the cleaning member 6 on the infrared glass 202 and the ultraviolet glass 203. After the rotating shaft 801 rotates counterclockwise to the limit position (rotation 135°), the rotating member 702 continues to rotate counterclockwise, and the connecting column 803 drives the cleaning brush 802 to rotate counterclockwise through the rotating shaft 801. The cleaning brush 802 sweeps off the impurities left on the infrared glass 202 and the ultraviolet glass 203, thereby improving the cleaning effect on the infrared glass 202 and the ultraviolet glass 203.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
