Description

Technical Field

[0001] The present invention generally relates to the field of waterproofing of meteorological equipment, and particularly to a water ingress detection device for equipment in the meteorological industry. Background Art

[0002] Equipment in the meteorological industry usually works in an outdoor environment. Therefore, equipment in the meteorological industry must have good sealing performance so that it can work properly in rainy and snowy environments. Therefore, after the equipment in the meteorological industry is assembled on the production line, it must be subjected to a waterproof performance test to confirm whether the waterproof performance requirements are met.

[0003] Equipment in the meteorological industry usually adopts a closed housing structure design. Without disassembling the machine, the internal condition of the equipment cannot be observed, so it is impossible to determine whether there is water immersion inside. If disassembly inspection is carried out, if the equipment has no water ingress, it needs to be assembled again. On the one hand, the production efficiency is reduced, and on the other hand, the equipment assembled again increases uncertain factors and increases the risk of waterproof performance failure.

[0004] Therefore, the inventor believes that there is a lack of a water ingress detection device for equipment in the meteorological industry on the market. Summary of the Invention

[0005] In view of the above problems existing in the prior art, according to the present invention, a water ingress detection device for equipment in the meteorological industry is provided, including: a perspective mirror hermetically installed at the detection port of the housing, a receiving groove is opened in a part of the perspective mirror located inside the housing, the receiving groove is opened from the upper direction to the bottom direction of the perspective mirror, a convex mirror is provided on a side of the receiving groove facing the outside of the housing, and the convex mirror is integrally provided with the perspective mirror; a superimposing mirror is horizontally arranged along the arc surface of the convex mirror at the center area of the surface of the convex mirror, and the superimposing mirror is integrally provided with the convex mirror; a detection paper for changing color when encountering water is fixed on the surface of the superimposing mirror; the detection paper is located within the focal point of the convex mirror. By having the above technical features, in the waterproof performance test of the meteorological equipment, the perspective mirror itself helps the tester to observe the water ingress situation inside the housing through the perspective mirror. Moreover, the opening of the receiving groove can, on the one hand, receive the dripping liquid, and on the other hand, also helps the water vapor to come into contact with the internal detection paper, so as to judge the sealing situation of the meteorological equipment through the color change of the detection paper; moreover, the cooperation of the convex mirror and the superimposing mirror ensures that the detection paper is within the focal range of the convex mirror, thereby having a magnifying effect on the detection paper and further improving the observation efficiency.

[0006] In some embodiments, the superimposed mirror is a strip-shaped lens with a circular cross section, and a liquid receiving groove is formed between the superimposed mirror and the convex mirror. Therefore, the liquid receiving groove formed by the horizontal arrangement of the superimposed mirror and the convex mirror can receive the water drops falling down, making it easy for the test personnel to observe the liquid in the liquid receiving groove and the water stains flowing down the convex mirror. In addition, the structure of the superimposed mirror itself makes the detection paper within the observation range within the focus, thereby ensuring the magnification effect of the detection paper.

[0007] In some embodiments, the convex mirror and the bottom part of the superimposed mirror are integrally arranged with the perspective mirror, so that the perspective mirror forms an upper water inlet observation area and an observation area inside the shell, so as to more comprehensively detect the water inlet condition of the meteorological equipment.

[0008] In some embodiments, the detection paper is arranged along the length direction of the superimposed mirror, and one side edge thereof extends into the liquid receiving tank. Thus, the area of the detection paper is increased, and the possibility of contact with the splashing water droplets is improved. In addition, the convex mirror plays a guiding role on the water droplets, so that the water droplets are concentrated in the liquid receiving tank, which will inevitably contact the detection paper to cause the color change, and also improve the observation effect of the test personnel.

[0009] In some embodiments, a connecting port is provided on the side wall of the receiving groove opposite to the detection paper, which is connected to the internal environment of the shell. Thus, the connecting area between the inside of the shell and the receiving groove is increased, which helps to connect the air in the area of the shell with the inside of the receiving groove. If the humidity in the shell is higher than the threshold, the detection paper will also change color.

[0010] In some embodiments, a liquid viewing channel is provided on the bottom wall of the receiving tank, the end of the liquid viewing channel is provided on the side of the perspective mirror facing the inside of the housing, and the middle of the liquid viewing channel is lower than the end of the liquid viewing channel. Thus, the liquid entering the receiving tank will enter the liquid viewing channel, and the liquid in the liquid viewing channel will remain at the bottom of the liquid viewing channel due to the principle of the communicating vessel, so as to facilitate the judgment of the test personnel, thereby greatly improving the accuracy of whether water has entered the meteorological equipment.

[0011] In some embodiments, the bottom wall of the receiving tank is an inclined surface inclined toward the inlet of the liquid observation channel, and the inlet of the liquid observation channel is the lowest point of the receiving tank. Thus, the liquid entering the receiving tank is guided, and the observation efficiency of the experimenter is improved.

[0012] In some embodiments, a sealing kit is fixed to the periphery of the perspective mirror, and the sealing kit is plugged into the detection port of the housing, thereby ensuring the sealing degree of the connection area of the perspective mirror and facilitating the disassembly of the perspective mirror.

[0013] In some embodiments, a lighting lamp is provided inside the sealing kit. Thus, the observation efficiency of the test personnel is improved.

[0014] It should be understood that the content described in the Summary of the Invention section is not intended to limit the key or important features of the embodiments of the present disclosure, nor is it used to limit the scope of the present disclosure. Other features of the present disclosure will become easily understood through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the preferred embodiments (or implementation manners) of the present invention will be described in detail with reference to the accompanying drawings.

[0023] Next, reference is made to Figures 1 - 5 to describe a water ingress detection device for a meteorological industry device of the present invention.

[0024] Figure 1 FIG. shows the overall structural schematic diagram of a water ingress detection device for a meteorological industry device according to an embodiment of the present invention. Referring to Figure 1 as shown, a water ingress detection device for a meteorological industry device provided in this embodiment is installed in the detection port of the meteorological industry device housing, and mainly includes an observation part in the middle and a sealing part covering the periphery of the observation part.

[0025] Among them, the observation part is mainly the perspective lens 1. The perspective lens 1 can be optical glass, such as K9 glass, which is applicable to the visible light to infrared band, about 350 - 2000 nm, and has high light transmittance, thermal stability and low refractive index; it can also be fused quartz, whose ultraviolet to infrared band is about 185 - 2100 nm, with relatively high transmittance, radiation resistance and no fluorescence effect, and a relatively low coefficient of thermal expansion.

[0026] In some embodiments, one side of the perspective lens 1 can adopt a coating process, which is optimized for different bands, and can reduce the single - side reflectivity to less than 0.5%, thereby improving the light transmittance. It can also adopt grinding and polishing processes to ensure the surface finish of the perspective lens 1 and improve the perspective rate.

[0027] The above - mentioned sealing part is a sealing kit 2 with a rubber plug body. A plurality of blocking sealing rings 21 are arranged on its peripheral side, so that after the sealing kit 2 is inserted into the housing detection port, the sealing effect of the inserted area is achieved, which is convenient for the tester to observe the sealing effect of the internal connection area of the housing through the perspective lens 1.

[0028] Figure 2 The structural schematic diagram of the perspective lens 1 in a water - inlet detection device of a meteorological industry device according to an embodiment of the present invention is shown. Refer to Figure 2 As shown, the perspective lens 1 is a lens body with a certain thickness, and its minimum thickness is 3 cm. The perspective lens 1 can be a rectangular lens body or a circular - shaped lens body. An accommodation groove 11 is opened from the upper direction of the perspective lens 1 to the lower direction of the perspective lens 1, so that the perspective lens 1 forms a liquid - holding part 12 in the upper half area and an intuitive part 13 in the lower half area. Moreover, the detection port of the housing is opened at the joint of the housing. When the waterproof performance of the housing is tested, the accommodation groove 11 of the perspective lens 1 needs to face the joint direction of the housing, and the joint area is placed at the top. If the housing leaks, the accommodation groove 11 plays a role in accommodating the dripping liquid, which is convenient for the tester to intuitively understand the sealing situation inside the housing through the perspective lens 1.

[0029] A convex lens 3 is arranged in the accommodation groove 11. The convex lens 3 is located on the side wall of the accommodation groove 11 facing the outside of the housing, and the convex lens 3 is integrally arranged with the perspective lens 1, so that the convex lens 3 and the side wall of the accommodation groove 11 form an integral plano - convex lens structure. The convex surface of the plano - convex lens has the function of converging light. When an object is within the focal point of the convex surface of the plano - convex lens, a virtual, upright and magnified image will be formed when observed from the plane side, similar to the structure of a traditional magnifying glass.

[0030] Figure 3 The cross - sectional view of a situation of the perspective lens 1 in a water - inlet detection device of a meteorological industry device according to an embodiment of the present invention is shown. Refer to Figure 3As shown in the figure, on the convex side of the convex mirror 3, a superimposed mirror 4 is horizontally arranged along the curvature of the convex surface in the central region thereof. The superimposed mirror 4 is integrally provided with the convex mirror 3. The cross-section of the superimposed mirror 4 is circular, and a partial area thereof is superimposed on the convex mirror 3, so that a liquid receiving groove 41 is formed between the superimposed mirror 4 and the convex mirror 3. If a liquid drops into the receiving groove 11 of the perspective mirror 1, the arc-shaped surface of the convex mirror 3 plays a role of guiding and draining the liquid, facilitating the drainage of the liquid into the liquid receiving groove 41, and facilitating the experimenter to observe the trace of the liquid flowing on the surface of the convex mirror 3 and the liquid remaining in the liquid receiving groove 41.

[0031] In some embodiments, a water-sensitive detection paper 5 is fixed on the surface of the superimposed mirror 4. The detection paper 5 is arranged along the length direction of the superimposed mirror 4 and spreads on the outer peripheral surface of the superimposed mirror 4, and one side edge of the detection paper 5 extends into the liquid receiving groove 41. The setting of the detection paper 5 increases the contact range with the liquid in many aspects. On the one hand, it can contact with the liquid in the liquid receiving groove 41, causing the detection paper 5 to change color; on the other hand, it spreads on the surface of the superimposed mirror 4, increasing its own surface area and the contact range with the external environment and even splashed liquid. Moreover, it further improves the observation effect of the experimenter. Since it is fixed on the surface of the superimposed mirror 4 and the cross-section of the superimposed mirror 4 is circular, its radial curvature may form a cylindrical lens effect similar to a cylindrical lens, producing a unidirectional magnification effect in the radial direction. Moreover, the superimposed mirror 4 has a curvature in the radial direction, which can further converge and diverge light in the radial direction. And the focal length of the superimposed mirror 4 is shorter than that of the plano-convex lens formed by the convex mirror 3 and the side wall of the perspective mirror 1, so the magnification of the convex mirror 3 and the superimposed mirror 4 will be enhanced, forming an asymmetric magnification effect, making the tiny color change on the detection paper 5 clearly visible.

[0032] Figure 4 The figure shows a cross-sectional view of another situation of the perspective mirror 1 in a water ingress detection device of a meteorological industry device according to an embodiment of the present invention. Refer to Figure 4 As shown in the figure, in some embodiments, in order to improve the magnification effect of the convex mirror 3 and the contact range between the detection paper 5 and the liquid, the above convex mirror 3 retains the partial structure above the central region as a whole convex mirror 3, and the upper part of the convex mirror 3 is filled in the receiving groove 11, so that the superimposed mirror 4 is closer to the bottom region of the receiving groove 11. When the liquid drops into the receiving groove 11, the splashed liquid is more likely to contact with the detection paper 5 on the surface of the superimposed mirror 4, thereby greatly improving the observation efficiency of the experimenter.

[0033] In some embodiments, a plurality of communication ports 14 are horizontally formed on the side of the receiving groove 11 facing away from the convex lens 3. The communication ports 14 are located in the horizontal area of the test paper 5, so that the air inside the housing is directly communicated with the bottom space of the receiving groove 11. If the humidity inside the housing is relatively high, the moist air can more easily enter the bottom of the receiving groove 11 through the communication ports 14 and come into contact with the test paper 5, greatly improving the discoloration efficiency of the test paper 5 and thus improving the accuracy of the waterproof detection.

[0034] Since the receiving groove 11 is located on the back side of the test paper 5, it is difficult to directly observe if there is liquid remaining in the receiving groove 11. Therefore, a liquid viewing channel 15 is formed on the bottom wall of the receiving groove 11. The other end of the liquid viewing channel 15 is opened on the side of the perspective lens 1 located inside the housing, and the middle area of the liquid viewing channel 15 is lower than the height of the outlet of the liquid viewing channel 15, so that the liquid entering the liquid viewing channel 15 can stay at the bottom of the liquid viewing channel 15 under the principle of a communicating vessel, facilitating the tester to directly observe the intrusion of the liquid.

[0035] In some embodiments, the entrance of the liquid viewing channel 15 is the lowest point of the bottom wall of the receiving groove 11, and the bottom wall of the receiving groove 11 is an inclined surface arranged towards the entrance of the liquid viewing channel 15, so that the liquid dripping into the receiving groove 11 will finally flow towards the direction of the liquid viewing channel 15 under the guidance of the inclined surface. The liquid viewing channel 15 can not only drain the excess liquid, but also retain some remaining water to prove the water immersion situation inside the housing.

[0036] Figure 5 The front view of a water inlet detection device in a meteorological industry device according to an embodiment of the present invention is shown. Refer to Figure 5 As shown, an LED lighting lamp 6 is also padded inside the sealing kit 2. The lamp beads of the lighting lamp 6 face the perspective lens 1, and the switch of the lighting lamp 6 is located outside the sealing kit 2. When the tester detects the waterproof performance result of the housing, by turning on the lighting lamp 6, it is not only convenient to observe the water immersion situation inside the housing, but also the overall perspective lens 1 is brightened, increasing the perspective effect and facilitating the tester to observe the color development of the test paper 5 and the remaining water residue.
