Description
Technical Field
[0001] This utility model relates to the field of coastal environmental monitoring technology, specifically to a salt-alkali resistant and waterproof intelligent monitoring sensor for coastal environments. Background Technology
[0002] As the area where land and sea meet, the coastal environment's aquatic ecological status is directly related to the regional ecological balance, aquaculture safety, and coastal environmental management. Therefore, accurate monitoring of key parameters such as dissolved oxygen in coastal waters is of great practical significance.
[0003] However, coastal environments are characterized by high salt spray concentrations, strong seawater corrosivity, high humidity, and strong ultraviolet radiation. Existing monitoring sensors have significant shortcomings when used in this environment:
[0004] First, the protective structure design is insufficient, and the main unit is easily corroded by sea wind, salt spray and rainwater, which can lead to electronic component failure.
[0005] Secondly, the sealing performance is poor, and seawater and saline solutions can easily seep into the connection between the core components of the sensor and the cable, causing the components to become damp, corroded and fail.
[0006] Third, the sensor has weak anti-aging and impact resistance. When exposed to sea breeze, ultraviolet rays and water flow for a long time, the sensor shell is prone to aging and damage, and the structural stability decreases.
[0007] These problems will lead to poor working stability and short service life of existing sensors in the harsh coastal environment, making it difficult to continuously and accurately collect monitoring data and failing to meet the actual needs of long-term stable monitoring of the coastal environment.
[0008] Therefore, it is necessary to design a salt- and alkali-resistant, waterproof intelligent monitoring sensor for coastal environments to solve the above problems. Utility Model Content
[0009] The purpose of this invention is to provide a salt- and alkali-resistant and waterproof intelligent monitoring sensor for coastal environments, in order to solve the problems mentioned in the background art.
[0010] To achieve the above objectives, this utility model provides the following technical solution: a salt-alkali resistant and waterproof intelligent monitoring sensor for coastal environments, comprising a column, a protective box fixedly connected to the top of the column, a sealing door rotatably connected to the front of the protective box, a main unit slidably connected to the inside of the protective box, a monitoring mechanism provided at the bottom of the main unit, and a fixing pin threadedly connected inside the main unit;
[0011] The monitoring mechanism includes a cable that is plugged into the bottom of the main unit. A dissolved oxygen sensor is fixedly connected to the bottom of the cable. A first sealing cover is slidably connected to the outer side of the right side of the dissolved oxygen sensor. A second sealing cover is plugged into the left side of the first sealing cover. A protective shell is slidably connected to the outer side of the dissolved oxygen sensor. The protective shell is threadedly connected to the outer side of the first and second sealing covers.
[0012] Preferably, the rear side of the main unit is in contact with the rear side inside the protective box, and the fixing pin passes through the inside of the protective box, so as to ensure the stability between the main unit and the protective box through the fixing pin.
[0013] Preferably, the sealing door is transparent, and the cable is slidably connected inside the protective box, allowing observation of the host's operating status and values through the transparency.
[0014] Preferably, the second sealing cover is slidably connected to the left periphery of the dissolved oxygen sensor, so that the dissolved oxygen sensor can be protected by the combined action of the second sealing cover and the first sealing cover.
[0015] Preferably, the protective shell includes a sealing buffer layer, an anti-seepage and anti-corrosion layer is fixedly spaced around the sealing buffer layer, a support layer is fixedly connected around the anti-seepage and anti-corrosion layer is fixedly connected around the support layer.
[0016] Preferably, the sealing buffer layer is the innermost layer, which is made of food-grade silicone rubber material, and the anti-aging protective layer is the outermost layer, which is coated with a fluorocarbon resin coating to facilitate the passage of food-grade silicone rubber. This not only enhances the sealing effect but also buffers the vibration and external impact during sensor operation.
[0017] Compared with the prior art, this utility model provides a salt-alkali-resistant and waterproof intelligent monitoring sensor for coastal environments, which has the following beneficial effects:
[0018] 1. This salt-alkali-resistant and waterproof intelligent monitoring sensor for coastal environments, through its monitoring mechanism, first secures the column with external fixing equipment to ensure the stability of the protective box when monitoring water bodies in the coastal environment using a dissolved oxygen sensor. The protective box is installed on top of the column, and together with a rotating sealed door, forms a double-protection structure for the main unit. The protective box can isolate the main unit from direct corrosion by sea breeze, salt spray, and rainwater in the coastal environment. The transparent sealed door ensures a good seal while allowing staff to easily observe the operating status of the main unit, preventing malfunctions caused by external environmental interference. The dissolved oxygen sensor is connected to a second... The sliding insertion of the sealing cover forms a preliminary seal, which is then combined with the threaded protective shell to achieve a secondary seal. The double sealing structure can effectively prevent seawater and saline solutions from seeping into the connection between the dissolved oxygen sensor and the cable, avoiding damage to the core components of the sensor due to moisture or corrosion. The main unit is assembled inside the protective box using a sliding connection method, and with the internal threaded fixing pin, it not only achieves a stable installation of the main unit, but also facilitates the disassembly, maintenance or replacement of the main unit in the future. Through the optimization of salt and alkali resistance, waterproofing and protective structure, the dissolved oxygen sensor can maintain a stable working state in the harsh coastal environment, and the dissolved oxygen sensor and other monitoring components can collect data without interference from the external environment.
[0019] 2. This salt-alkali-resistant and waterproof intelligent monitoring sensor for coastal environments employs a multi-layered composite structure for its protective shell, consisting of a sealing buffer layer, an anti-seepage and anti-corrosion layer, a support layer, and an anti-aging protective layer. Each layer complements the others. The innermost food-grade silicone rubber sealing buffer layer not only enhances the sealing effect but also buffers vibrations and external impacts during sensor operation. The outermost anti-seepage and anti-corrosion layer is made of fluororubber, resisting corrosion from the high-salt-alkali environment of the coast. It exhibits extremely low permeability to salt, ozone, grease, and various chemical substances, serving as the ultimate barrier against the intrusion of high-concentration saline-alkali water vapor. The support layer surrounding the anti-seepage and anti-corrosion layer is made of marine-grade aluminum alloy, providing stable structural strength. The outermost anti-aging protective layer, coated with fluorocarbon resin, effectively resists aging caused by sea winds and ultraviolet rays, improving the durability of the protective shell and extending the overall lifespan of the sensor, while also achieving salt-alkali-resistant and waterproof performance.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] This utility model provides the following technical solution:
[0032] Example 1
[0033] Please see Figure 1-7This utility model provides a technical solution: a salt-alkali-resistant and waterproof intelligent monitoring sensor for coastal environments, including a column 1, a protective box 2 fixedly connected to the top of the column 1, a sealing door 4 rotatably connected to the front of the protective box 2, a main unit 5 slidably connected to the inside of the protective box 2, a monitoring mechanism 3 set at the bottom of the main unit 5, and a fixing pin 6 threadedly connected inside the main unit 5.
[0034] The monitoring device 3 includes a cable 31, which is plugged into the bottom of the host 5. A dissolved oxygen sensor 32 is fixedly connected to the bottom of the cable 31. A first sealing cover 33 is slidably connected to the right periphery of the dissolved oxygen sensor 32. A second sealing cover 34 is plugged into the left side of the first sealing cover 33. A protective shell 35 is slidably connected to the periphery of the dissolved oxygen sensor 32. The protective shell 35 is threadedly connected to the periphery of the first sealing cover 33 and the second sealing cover 34.
[0035] The rear side of the main unit 5 is in contact with the rear side inside the protective box 2, and the fixing pin 6 passes through the inside of the protective box 2, so as to ensure the stability between the main unit 5 and the protective box 2 through the fixing pin 6.
[0036] The sealed door 4 is transparent, and the cable 31 is slidably connected inside the protective box 2, allowing the working status and values of the main unit 5 to be observed through the transparent door.
[0037] The second sealing cover 34 is slidably connected to the left periphery of the dissolved oxygen sensor 32, so that the dissolved oxygen sensor 32 can be protected by the combined action of the second sealing cover 34 and the first sealing cover 33.
[0038] Example 2
[0039] Please see Figure 1-7 Furthermore, based on Embodiment 1, the protective shell 35 further includes a sealing buffer layer 7, an anti-seepage and anti-corrosion layer 8 is fixedly spaced around the sealing buffer layer 7, a support layer 9 is fixedly connected around the anti-seepage and anti-corrosion layer 8, and an anti-aging protective layer 10 is fixedly connected around the support layer 9.
[0040] The innermost layer is the sealing buffer layer 7, which is made of food-grade silicone rubber. The outermost layer is the anti-aging protective layer 10, which is coated with a fluorocarbon resin coating to facilitate the passage of food-grade silicone rubber. This not only enhances the sealing effect but also buffers the vibration and external impact during sensor operation.
[0041] In actual operation, when this device is used to monitor the water body in the coastal environment through the dissolved oxygen sensor 32, the column 1 is first fixed by the external fixing equipment so that the protective box 2 is located near the monitored water body to ensure the stability of the protective box 2. The main unit 5 is assembled inside the protective box 2 by sliding connection and with the fixing pin 6 with internal thread connection. This not only achieves the stable installation of the main unit 5, but also facilitates the disassembly, maintenance or replacement of the main unit 5 in the later stage. The protective box 2, together with the rotating sealing door 4, forms a double protection structure for the main unit 5. The protective box 2 can isolate the main unit 5 from the direct corrosion of sea wind, salt spray and rainwater in the coastal environment. The transparent sealing door 4 can not only ensure the sealing effect, but also make it easy for the staff to observe the operating status of the main unit 5 and avoid the main unit 5 from malfunction due to external environmental interference.
[0042] After the connection is completed, the dissolved oxygen sensor 32 is initially sealed by the sliding insertion of the first sealing cover 33 and the second sealing cover 34. Then, the protective shell 35 with threaded connection is used to achieve a secondary seal. The double sealing structure can effectively prevent seawater and saline solution from seeping into the connection part between the dissolved oxygen sensor 32 and the cable 31, and avoid damage to the core components of the sensor due to moisture or corrosion. After the connection and protection are completed, the cable 31 can be connected to the host 5, and the dissolved oxygen sensor 32 can be placed into the water body to be monitored for monitoring.
[0043] The protective shell 35 adopts a multi-layer composite structure consisting of a sealing buffer layer 7, an anti-seepage and anti-corrosion layer 8, a support layer 9, and an anti-aging protective layer 10. Each layer has complementary functions. The innermost food-grade silicone rubber sealing buffer layer 7 not only enhances the sealing effect but also buffers the vibration and external impact during sensor operation. The anti-seepage and anti-corrosion layer 8 around the sealing buffer layer 7 is made of fluororubber material, which can resist the corrosion of the high salinity and alkalinity environment of the coast. It has extremely low permeability to salt, ozone, oil and various chemicals, and is the ultimate barrier against the intrusion of high concentrations of saline and alkaline water vapor. The support layer 9 around the anti-seepage and anti-corrosion layer 8 is made of marine-grade aluminum alloy material, which provides stable structural strength. The outermost anti-aging protective layer 10, which is coated with fluorocarbon resin, can effectively resist aging caused by sea wind and ultraviolet rays, improve the durability of the protective shell 35, and thus extend the service life of the entire sensor. It can also achieve anti-salt and waterproof effects.
[0044] Through optimization of salt and alkali resistance, waterproofing and protective structure, dissolved oxygen sensor 32 can maintain stable working status in harsh coastal environment, and monitoring components such as dissolved oxygen sensor 32 can collect data without interference from the external environment.
[0045] The dissolved oxygen sensor used in this case is model 32: Oxymax COS61D.
