Description

Technical Field

[0001] This utility model relates to the field of sensor mounting housing technology, and in particular to a sensor windowed encapsulation housing with a protective structure. Background Technology

[0002] Sensors, as core components for signal acquisition and data monitoring, are widely used in various fields such as industrial automation, environmental monitoring, security monitoring, and intelligent device terminals. In most application scenarios, sensors need to expose the detection end (such as optical probes, gas sensors, and acoustic sensors) through a windowed enclosure to ensure that the detection signal (light, gas, sound waves, etc.) can be transmitted smoothly and to achieve accurate acquisition of target parameters.

[0003] The windows of existing sensor mounting housings cannot provide protection in both working and non-working states, making it easy for dust, moisture, and foreign objects to intrude and adhere to the surface of the detection unit, which can affect the detection accuracy of the sensor and cause corrosion damage to the components. To address this, we propose a sensor windowed enclosure housing with a protective structure. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1:

[0032] Reference Figures 1-9 This is the first embodiment of the present invention. This embodiment provides a sensor windowed enclosure housing with a protective structure, including an outer shell 1, a sensor body 11 disposed inside the outer shell 1, bolts 12 for fixing the sensor body 11 disposed on the outer wall of the outer shell 1, a window 2 disposed at the front end of the outer shell 1, a fixed protective component 3 detachably installed inside the window 2, and a movable protective component 4 that can automatically open and close according to the working state of the sensor body 11 installed inside the window 2.

[0033] When the sensor body 11 is not activated, the active protection component 4 is in a closed state.

[0034] Under the initial thread limit of the bidirectional screw 45, the two sets of sealing plates 42 are attached to each other along the guide grooves 41 on both sides of the window 2, completely sealing the outer channel of the window 2, preventing external dust, moisture and foreign objects from directly entering the interior of the housing 1, and forming physical isolation protection for the sensor body 11.

[0035] The fixed protective component 3 is kept fixed by an elastic snap-fit ​​structure; the outer frame 31 is embedded inside the window 2, and the spring sheet 34 in the slide 32 is in a naturally extended state, pushing the slider 33 to snap into the slot 35 on the inner wall of the window 2, so that the outer frame 31 is tightly fixed to the inner wall of the window 2. The filter membrane 311 inside covers the inner channel of the window 2, forming a fixed protection, further blocking fine impurities from entering the detection area of ​​the sensor body 11.

[0036] When the sensor body 11 receives the working command, its control terminal outputs an electrical signal and transmits it to the drive motor 46 (the drive motor 46 is electrically connected to the control module of the sensor body 11 and receives the working status signal in real time). The drive motor 46 drives the active protection component 4 to open the window 2.

[0037] After receiving the working signal, the output end of the drive motor 46 drives the bidirectional screw 45 to rotate around its own axis. The positive and negative thread sections of the bidirectional screw 45 respectively mesh with the thread grooves 44 of the two sets of guide members 43. Since the threads rotate in opposite directions, when the bidirectional screw 45 rotates in the forward direction, the two sets of guide members 43 generate reverse driving force along the thread grooves 44, which drives the sealing plate 42 to slide synchronously to both sides of the window 2 along the guide grooves 41.

[0038] During the sliding process of the sealing plate 42, the cleaning component 421 installed on the side surface near the inside of the outer shell 1 simultaneously adheres to the outer surface of the filter membrane 311 of the fixed protective component 3. As the sealing plate 42 moves, it wipes and cleans the dust and impurities attached to the surface of the filter membrane 311, so as to avoid the filter membrane 311 from being blocked and affecting the detection accuracy of the sensor.

[0039] When the two sets of sealing plates 42 slide to the end of the guide groove 41, they are limited, the outer channel of the window 2 is fully opened, and the sensor body 11 is connected to the external detection environment through the inner filter membrane 311 of the window 2, so as to carry out signal acquisition, data detection and other work normally.

[0040] When the sensor body 11 completes the detection task (in standby or power-off state), its control terminal stops outputting working signals, and the drive motor 46 receives the stop signal.

[0041] Then, the drive motor 46 reverses and drives the bidirectional screw 45 to rotate in the opposite direction. The positive and negative thread sections drive the two sets of guide members 43 to move towards each other through the thread groove 44, thereby pulling the sealing plate 42 to slide along the guide groove 41 toward the center of the window 2.

[0042] After the two sets of sealing plates 42 are re-attached, the outer channel of window 2 is closed, and the cleaning component 421 moves with the return of the sealing plate 42 to perform a second cleaning on the surface of the filter membrane 311 to ensure that the filter membrane 311 remains permeable.

[0043] At this point, the device returns to its initial state. The physical sealing of the sealing plate 42 and the filtration protection of the filter membrane 311 form a double barrier, continuously protecting the sensor body 11 in the non-working state.

[0044] This solution uses a drive motor 46 to link with the working state of the sensor body 11, enabling the automatic opening and closing of the window 2 without manual intervention. The window opens when the sensor starts and closes when it stops, making it suitable for automated detection scenarios and reducing maintenance costs. It is especially suitable for unattended, remotely controlled sensor installation environments. When the window is closed, the two sets of sealing plates 42 completely seal the outer channel of the window 2, preventing external dust, moisture, and foreign objects from directly entering the housing 1, thus providing physical isolation and protection for the sensor body 11. When the window is open, the filter membrane 311 protects against dust, moisture, and foreign objects in the environment, preventing them from affecting the sensor's detection accuracy and causing corrosion damage to the components.

[0045] It should be noted that, based on the above embodiments, the control circuit of this solution includes a motor drive module, a sensor main control module, and a voltage regulator module. The external power supply is connected to the voltage regulator module, and after being stepped down, filtered, and regulated by the voltage regulator module, two stable DC voltages are output.

[0046] The first path is connected to the motor drive module via a power connection cable. At the same time, the motor drive module is connected to the positive and negative terminals of the drive motor 46 via a power connection cable to provide it with power.

[0047] The second path connects to the sensor's main control module via a power cable, providing control power to the sensor's main control module and ensuring that the sensor's main control module outputs control signals stably.

[0048] Example 2:

[0049] Reference Figure 4 , Figure 7 and Figure 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0050] Specifically, the active protective component 4 includes guide grooves 41 corresponding to the inner walls on both sides of the window 2. Both guide grooves 41 have sealing plates 42 slidably installed inside them. When the two sealing plates 42 are closed, they close the window 2.

[0051] The sealing plate 42 is integrally molded from high-strength engineering plastic. An elastic sealing strip is embedded on the edge of its end face facing the outside of the window 2. The length of the sealing plate 42 is completely matched with the width of the window 2, and the width covers the height range of the window 2. When the two sets of sealing plates 42 are in the closed state, their opposite end faces are tightly fitted together.

[0052] Specifically, a guide member 43 is fixedly installed on the outer wall of the sealing plate 42. The end of the guide member 43 extends through the inner wall of the outer shell 1 to the internal space of the outer shell 1. Each guide member 43 is coaxially provided with a threaded groove 44. The movable protective assembly 4 also includes a bidirectional screw 45. The positive and negative threads of the bidirectional screw 45 are respectively threaded to the two threaded grooves 44. Both ends of the bidirectional screw 45 are rotatably installed inside the outer shell 1 through bearings. A drive motor 46 is provided at one end of the bidirectional screw 45. The drive motor 46 is installed inside the outer shell 1 through a bracket. The output end of the drive motor 46 is coaxially fixed with the end of the bidirectional screw 45.

[0053] When in use, the drive motor 46 starts, which can drive the bidirectional screw 45 to rotate in the forward or reverse direction, drive the two sets of guide members 43 to move synchronously, and pull the sealing plate 42 to slide along the guide groove 41.

[0054] Example 3:

[0055] Reference Figure 3 , Figure 4 , Figure 8 and Figure 9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the fixed protective component 3 includes an outer frame 31, which is located inside the window 2 and is positioned on the side of the guide groove 41 close to the sensor body 11. Slide grooves 32 are provided on the outer walls of the corresponding two ends of the outer frame 31. A slider 33 is slidably installed inside the slide groove 32. A slot 35 for connecting the slider 33 is provided on the inner wall of the window 2. A spring plate 34 is installed inside the slide groove 32, and one end of the spring plate 34 is installed on the outer wall of the slider 33.

[0057] During installation, the outer frame 31 is aligned with the window 2 and embedded. The slider 33 automatically pops out and snaps into the slot 35 under the elastic thrust of the spring plate 34, thus completing the quick fixation.

[0058] Specifically, a filter membrane 311 is installed inside the outer frame 31 (i.e., the hollow area of ​​the frame).

[0059] The filter membrane 311 is one of the following: PTFE waterproof and breathable filter membrane, polyester fiber dustproof filter membrane, or fluorocarbon anti-corrosion filter membrane. The filter membrane 311 is selected according to the application scenario of the sensor. In environmental monitoring scenarios, PTFE waterproof and breathable filter membrane is selected; in dusty environments, polyester fiber dustproof filter membrane is selected; and in corrosive environments, fluorocarbon anti-corrosion filter membrane is selected.

[0060] Specifically, a cleaning component 421 is installed on the side surface of the sealing plate 42 near the inside of the outer casing 1.

[0061] This solution integrates a cleaning component 421 on the sealing plate 42. The opening and closing sliding of the sealing plate 42 enables synchronous cleaning. During each opening or closing of the window, the cleaning component 421 wipes the surface of the filter membrane 311 to remove attached impurities in real time, preventing the filter membrane 311 from clogging. There is no need to set up an additional cleaning mechanism or frequently disassemble and maintain it, which greatly reduces the replacement frequency and maintenance cost of the filter membrane 311.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
