Description

Technical Field

[0001] This utility model relates to the technical field of water ingress detection equipment, specifically to a sealed water ingress observation window device. Background Technology

[0002] In industrial production, speed reducers are widely used in various mechanical equipment. Their structure mainly consists of independent components composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing. They are commonly used as speed reduction transmission devices between the prime mover and the working machine, and play a role in matching speed and transmitting torque between the prime mover and the working machine or actuator. They are extremely widely used in modern machinery.

[0003] It should be noted that since the speed reducer needs to be connected to the prime mover at high speed, wear and heat will inevitably occur during operation. At present, the main way to reduce wear is to fill the speed reducer with lubricating oil, while water cooling is used to cool the speed reducer from the outside.

[0004] However, coolant and lubricating oil are only separated by the housing. If the housing is damaged, coolant will enter the motor through the transition housing, causing the motor performance to decline or even fail completely. It is often difficult to judge whether the housing is damaged from the appearance of the motor alone. Therefore, an observation device that can directly observe the internal condition of the reducer is needed. Utility Model Content

[0005] Therefore, this utility model provides a sealed water ingress observation window device to solve the problem in the prior art that it is impossible to observe the intrusion of coolant or water into the motor due to damage to the casing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The sealing element has an observation hole at its end, which is disposed through the axis of the sealing element.

[0009] A convex lens is mounted in place at the tail end of the observation hole;

[0010] A teleconverter is mounted at the beginning of the observation port;

[0011] The transition housing is coated with a water-testing paste, the intensifier is inserted into the observation hole and is adapted to slide within the observation hole, and the water-testing paste is adapted to be observed by the naked eye through the observation hole.

[0012] Furthermore, the seal includes:

[0013] The head is integrally formed with the microscope tube at the axis, and the observation hole is located at the axis of the head and passes through the microscope tube;

[0014] A sealing groove is provided at the connection position between the head and the lens barrel, and a rubber sealing ring is suitable for being installed in the sealing groove.

[0015] Furthermore, the teleconverter is a transparent cylinder, and a dial is provided on the outside of the teleconverter;

[0016] The teleconverter has an external thread on its exterior, and the external thread of the teleconverter and the internal thread of the observation hole form a helical pair.

[0017] Furthermore, the head is a regular hexagon or a circle.

[0018] Furthermore, the convex lens is an ultra-wide-angle lens or a fisheye lens.

[0019] Furthermore, the number of sealed water inlet observation windows installed on the transition housing is not less than two.

[0020] Furthermore, the head is provided with two or more countersunk holes.

[0021] This utility model has the following advantages:

[0022] This utility model discloses a sealed water ingress observation window device, which is mainly installed on the transition shell. Through a convex lens, it can capture a large area of ​​scenery within a short shooting distance. Simultaneously, a magnifying glass is used to extend the focal length for easier naked-eye observation. Furthermore, the lens barrel can be inserted into the equipment to improve the sealing effect between the lens barrel and the transition shell. Compared to existing technologies, the observation window device can effectively observe the color of the water-testing paste inside the transition shell. If the shell is damaged, the color of the water-testing paste will change, allowing direct identification of water intrusion into the motor and timely repair. Attached Figure Description

[0032] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Please refer to this as well. Figures 1-6 This utility model discloses a sealed water inlet observation window device, installed on a transition shell, including a sealing element 1, a convex lens 3, and a magnifying lens 5. The convex lens 3 is an ultra-wide-angle lens or a fisheye lens, characterized by a short focal length and a wide angle of view, allowing for the capture of a large area of ​​scenery within a short distance. Based on this structure, the sealing element 1 has an observation hole 2 at its end, through which the entire sealing element 1 can pass. The convex lens 3 is embedded at the tail end of the observation hole 2, thereby effectively observing the situation inside the transition shell.

[0034] In this embodiment, a convex lens 3 is embedded at the tail end of the observation hole 2, and a magnifying lens 5 is provided at the head end of the observation hole 2. A water-testing paste is applied inside the transition housing. The magnifying lens 5 is inserted into the observation hole 2 and is adapted to slide within it. The water-testing paste can be observed with the naked eye through the convex lens 3 and the magnifying lens 5. When water comes into contact with the water-testing paste, the paste will quickly change color, producing a noticeable change, allowing observation of whether water has entered the transition housing.

[0035] In this embodiment, a magnifying lens 5 is provided at the first end of the observation hole 2. The magnifying lens 5 is a transparent cylinder. When light passes through the convex lens 3, it enters the magnifying lens 5 through the air gap between the convex lens 3 and the magnifying lens 5. Since the material of the magnifying lens 5 is a light-dense medium compared to air, the light will be focused to a farther position in the magnifying lens 5. Therefore, a longer sealing element 1 can be installed on the transition shell, thereby making the sealing effect of the sealing element 1 better.

[0036] In some embodiments, the seal 1 includes a head 11, a sealing groove 12, and a lens barrel 13. The head 11 is integrally formed with the lens barrel 13 along its axis. An observation hole 2 is located along the axis of the head 11 and extends through the lens barrel 13. A teleconverter 5 is inserted into the observation hole 2 and is adapted to slide within it. The test gel can be observed with the naked eye through the convex lens 3 and the teleconverter 5. In use, the focal length can be adjusted by adjusting the teleconverter 5, thereby effectively observing the internal condition of the transition shell. On the other hand, a sealing groove 12 is provided at the connection position between the head 11 and the lens barrel 13. A rubber sealing ring is suitable for being installed in the sealing groove 12 to prevent lubricating oil or coolant from leaking from the observation hole 2. The head 11 is provided with two or more countersunk holes 6, and fasteners are installed in the countersunk holes 6 to fix the seal 1 to the equipment.

[0037] In this embodiment, as Figure 2 The teleconverter 5 is a transparent cylinder. Light enters from the end of the teleconverter 5 and is refracted, thus extending the focal length. A dial 4 is fitted around the teleconverter 5, and an external thread 7 is provided on the teleconverter 5. This external thread 7 and the internal thread in the observation hole 2 form a helical pair. In use, rotating the dial 4 rotates the teleconverter 5, thereby adjusting the distance between the teleconverter 5 and the convex lens 3, thus adjusting the focal length and achieving a clear image. This allows for clear observation of the color of the water-based gel.

[0038] In this embodiment, as Figure 2The head 11 is hexagonal or circular. By rotating the head 11 with a wrench, the lens barrel 13 can be screwed into the transition housing with an interference fit, effectively preventing lubricant leakage. Alternatively, fasteners can be installed in the countersunk hole 6 to secure the seal 1, and a rubber sealing ring can be used to enhance the sealing effect. Specifically, the transition housing is equipped with at least two sealed water ingress observation windows, allowing external light to enter the housing for visual observation, and also allowing for observation of water intrusion issues by shining a light into the transition housing.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
