Description

Technical Field

[0001] The present application relates to the technical field of sensor bodies, and in particular to a waterproof housing for a sensor capable of maintaining the detection accuracy of the sensor body. Background Art

[0002] Underwater exploration environmental testing is a complex process of comprehensive monitoring and in-depth analysis of various physical, chemical and biological environmental factors underwater. It covers a wide range of physical factors such as water temperature, water pressure, and water flow velocity, chemical indicators such as dissolved oxygen, pH, and pollutant content in water quality, as well as detection of seabed topography and marine biological activities. This process is of vital importance to many fields such as scientific research, resource development, and environmental protection.

[0003] In underwater survey environment detection, the sensor body is mainly used to assist in detection. This is because the underwater environment is extremely complex and full of dangers. Humans face great difficulties in direct detection. It is not only costly but also extremely risky. In contrast, the sensor body can work stably in harsh underwater environments and is completely unaffected by factors such as water pressure and water flow. Secondly, the sensor body has extremely high accuracy and sensitivity and can accurately measure various tiny environmental changes. For example, the sensor body can quickly and accurately detect slight changes in water temperature or trace amounts of specific chemicals in water. Furthermore, the sensor body can realize real-time monitoring and continuously transmit data to the ground control center, so that people can grasp the dynamic changes of the underwater environment in a timely manner. At the same time, different types of sensor bodies can be used in combination to fully cover all aspects of the underwater environment and provide rich and accurate data support for scientific research and engineering applications.

[0004] The Chinese patent with the announcement number "CN207991609U" discloses an underwater exploration environment detection probe, which includes a waterproof probe, a protective box and a controller. The waterproof probe is connected to the protective box through a waterproof connection line. A power switch is fixed on the side of the protective box, a display screen is embedded at the rear, and function buttons are installed under the display screen. A sampling sealing plate is installed inside the sampling port, and a flow sensor body and a water quality heavy metal sensor body are embedded at the bottom of the waterproof shell, and a pH value sensor body is embedded on the right side. This underwater exploration environment detection probe integrates multiple detection devices such as temperature detection and water flow detection, has a compact structure, and is easy to carry. At the same time, a water quality heavy metal sensor body is set inside the equipment to cooperate with a high-impedance amplifier, which can effectively detect the hardness of the water body and better perform exploration environment detection work, which has played a positive role in promoting the development of the exploration equipment industry;

[0005] However, the above sensor body detection device does have some obvious defects in the actual application process. First, when using the device, it is extremely inconvenient to adjust the depth position of the sensor body waterproof probe in the water body, and the flexibility is poor. Usually, it is often necessary to rely on manual operation and adjustment, which undoubtedly increases the complexity of the operation. Moreover, manual adjustment is prone to errors, resulting in inaccurate adjustment results. Second, when the waterproof probe needs to be placed in the water body for a long time for detection, plankton, algae and some dust impurities in the water body will gradually adhere to the outer surface of the waterproof probe. Although the waterproof probe is waterproof, it will not be easy to cause the waterproof probe to be damaged. The probe has a waterproof function, but lacks an effective cleaning structure. As the waterproof probe stays in the water for a longer time, its outer surface is very easy to be completely blocked and covered by these attachments. As a result, poor contact between the waterproof probe and the water body will occur. Obviously, as the number of attachments increases, the degree of attachment continues to increase, which will inevitably have a great impact on the overall detection accuracy of the device for the water body. It can be seen that the device cannot always maintain a stable water body detection function during the overall use period. In terms of practical application, there are indeed certain defects and deficiencies. In view of this, it is urgent to improve the device. Summary of the invention

[0035] Please refer to Figure 1-Figure 5 and Figure 8The adjustment mechanism 6 includes a fixing plate 61, which is installed on the lower front end of the waterproof housing by bolts. The front of the fixing plate 61 is fixedly connected to a vertical rail 62, and the top of the vertical rail 62 is fixedly connected to a waterproof motor 63. The output end of the waterproof motor 63 passes through the vertical rail 62 and is fixedly connected to a screw rod 64.

[0036] Please refer to Figure 1-Figure 5 and Fig. 9The cleaning mechanism 9 includes a transmission gear 91 and a mounting ring 92. The transmission gear 91 is fixedly mounted on the lower end of the screw rod 64. The mounting ring 92 is fixedly mounted on the lower end of the front face of the vertical rail 62. The internal rotation of the mounting ring 92 is connected with a slip ring 93. The outer side of the slip ring 93 is fixedly connected with a gear ring 94. The gear ring 94 is meshed with the transmission gear 91. The inner side of the slip ring 93 is fixedly connected with a cleaning ring sleeve 95. The inner side of the cleaning ring sleeve 95 is fixedly connected with a brush 96. The cleaning ring sleeve 95 is arranged directly below the waterproof probe 11. The transmission gear 91 is connected to the lower end of the screw rod 64. When the screw rod 64 rotates, it can drive the transmission gear 91 to rotate. The mounting ring 92 provides stable support for the internal slip ring 93. The gear ring 94 on the outer side of the slip ring 93 is connected with the transmission gear 91. The meshing enables the power of the screw 64 to be transmitted to the slip ring 93. The cleaning ring sleeve 95 inside the slip ring 93 and the brush 96 inside the slip ring 93 are cleverly designed. When the screw 64 rotates to adjust the height of the waterproof probe 11, the transmission gear 91 drives the gear ring 94 to rotate, thereby rotating the slip ring 93 and the cleaning ring sleeve 95. The cleaning ring sleeve 95 is located just below the waterproof probe 11. As the cleaning ring sleeve 95 rotates, the brush 96 can brush and clean the outer surface of the waterproof probe 11, effectively preventing dust, plankton or algae from adhering to the waterproof probe 11, maintaining a good contact effect between the waterproof probe 11 and the water body, ensuring that the sensor body 2 can always perform high-precision detection, and greatly improving the reliability and stability of the device in an underwater environment.

[0037] The implementation principle of a waterproof housing for a sensor that can maintain the detection accuracy of the sensor body in the embodiment of the present application is as follows: by setting up a mounting mechanism 3, great convenience is brought to the device during use. When using the device, the sensor body 2 can be inserted into the interior of the waterproof housing 1. During this operation, the fixing ear 5 will be inserted into the interior of the card frame 32. Then, the pull ring 346 is pushed to drive the sliding rod 342 inside the support frame 341 to slide upward. As the sliding rod 342 moves upward, the hinge seat 343 will be driven to move upward together. After the hinge seat 343 moves upward, the linkage rods 344 at both ends will also rise accordingly. During the upward movement of the linkage rod 344, the connecting block 345 will be pulled. Since the linkage rod 344, the connecting rod and the limit arm 334 are rotatably connected to each other, the connecting block 345 can drive the two limit arms 334 to rotate synchronously in cooperation with the rotation of the linkage rod 344. When the locking nut 332 is unlocked, the locking nut 333 is unlocked and the locking nut 334 is unlocked, and the locking nut 333 is unlocked, so that the locking nut 333 is unlocked and the locking nut 334 is unlocked.

[0038] By setting the adjustment mechanism 6, the device exhibits many advantages during use. First, the waterproof motor 63 can be started to run. When the waterproof motor 63 is started, the screw rod 64 located on the inner side of the vertical rail 62 can be driven to rotate. The rotation of the screw rod 64 can drive the slider 65 to slide on the inner side of the vertical rail 62. As the slider 65 slides up and down, the straight tube 8 on the inner side of the fixing component 66 can be driven to move up and down. In this way, the height of the waterproof probe 11 can be flexibly adjusted. It can be seen that the waterproof probe 11 of the device can flexibly adjust the water level it detects. The depth improves the detection adaptation performance of the device as a whole during application. Moreover, during use, when the sensor body 2 needs to be disassembled and replaced, the screw rod 662 can be driven to rotate by twisting the adjusting knob handle 663, so that the screw rod 662 moves outward. At this time, the straight tube 8 together with the waterproof probe 11 can be removed from the inside of the fixing ring 661. It can be seen that the device as a whole is convenient for fixing the waterproof probe 11 and replacing the sensor body 2. During use, as the screw rod 64 rotates, the transmission gear 9 at the bottom can be driven by the screw rod 64. 1 rotates, because the transmission gear 91 and the gear ring 94 are meshed and connected, the gear ring 94 can be driven to rotate with the rotation of the transmission gear 91, and the gear ring 94 drives the slip ring 93 to rotate, and the rotation of the slip ring 93 can drive the cleaning ring 95 to rotate. During this period, the waterproof probe 11 just drives the slider 65 to move up and down through the screw rod 64 to adjust the height. At this time, as the waterproof probe 11 moves up and down, the waterproof probe 11 can move up and down inside the cleaning ring 95. In this process, as the cleaning ring 95 rotates, the brush 96 can be driven to The outer surface of the waterproof probe 11 is brushed and cleaned. It can be seen that the device as a whole can drive the cleaning ring 95 of the cleaning mechanism 9 to rotate by the power of the waterproof motor 63 and the screw 64. As the cleaning ring 95 rotates, the brush 96 inside the cleaning ring 95 can be prompted to stably clean the waterproof probe 11. This can effectively prevent the outer surface of the waterproof probe 11 from being attached by dust, plankton or algae, and can maintain the contact effect between the waterproof probe 11 of the device and the water body when it is located inside the water body for a long time, and can maintain a high-precision detection state for a long time.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
