Technical Field
[0001] This utility model relates to the field of marine environmental monitoring technology, specifically to a marine buoy water quality sensor housing structure that prevents biofouling. Background Technology
[0002] With the increasing demand for marine environmental monitoring, marine buoy water quality sensors are widely used for real-time monitoring of key parameters such as seawater temperature, salinity, dissolved oxygen, pH, and turbidity. However, the adhesion of marine organisms (such as barnacles, mussels, and algae) to the sensor shell surface seriously affects the measurement accuracy and service life of the sensor, especially in the waterline area where adhesion is most severe. Common anti-biofouling technologies mainly use chemical antifouling coatings, such as organotin or copper-based coatings. Although these can effectively inhibit biofouling, they pose a risk of environmental pollution, and the coatings are prone to wear and the maintenance process is relatively cumbersome. Therefore, there is an urgent need for an anti-biofouling marine buoy water quality sensor shell structure. Utility Model Content

[0011] Abutting rod, comprising several abutting rods, is fixedly mounted on several limiting blocks. A spring is movably sleeved on the abutting rod, and one end of the abutting rod is movably inserted into the vertical bar and movably abuts against the positioning block.
[0012] Furthermore, gears are fixedly fitted at the upper ends of several threaded rods, and a gear ring is rotatably mounted inside the housing via bearings, with several gears meshing with the gear ring.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] like Figures 1-7 As shown, this specific embodiment adopts the following technical solution: it includes a housing 1, and the upper part of the housing 1 is set with an arc-shaped structure;
[0028] It also includes:
[0029] Antifouling strip 2 is abutting against the outside of the shell 1. Permanent magnet 3 and magnetically conductive metal sheet 4 are fixedly installed inside both ends of the antifouling strip 2. The permanent magnet 3 and magnetically conductive metal sheet 4 are adsorbed together. The antifouling strip 2 is composed of a polyvinyl alcohol and chitosan blend matrix and loaded with capsaicin and indole composite antifouling agent. It can slowly dissolve in the seawater environment, thereby releasing the antifouling agent and preventing biofouling.
[0030] The locking blocks 5, which are several in number, are distributed on the upper and lower sides of the inner ring wall of the anti-fouling strip 2 with equal rounded corners. Several slots 6 are opened on the outer side wall of the housing 1. The locking blocks 5 are locked in the slots 6. The opening of the slot 6 is provided with an inclination angle 17, and the inclination angle 17 is set to cooperate with the chamfer on the locking block 5. The inclination angle 17 can provide guidance during the process of locking the locking block 5 into the slot 6, which improves the convenience of locking the locking block 5 into the slot 6 and also makes the assembly of the anti-fouling strip 2 more convenient.
[0031] The limiting block 9, of which there are several, is movably abutting against the limiting groove 10 opened on the several locking blocks 5, and the limiting block 9 is movably inserted into the groove 7 opened on the inner wall of the locking groove 6. A spring 8 fixedly connected to the limiting block 9 is fixedly installed in the groove 7. The housing 1 is provided with a limiting mechanism 11 connected to the limiting block 9. A sealing ring 16 is fixedly installed in the annular groove opened on the inner wall of the groove 7, and the sealing ring 16 is movably sleeved on the limiting block 9. The sealing ring 16 can improve the sealing performance of the gap between the limiting block 9 and the groove 7, and prevent seawater from seeping into the interior of the groove 7.
[0032] The limiting mechanism 11 includes:
[0033] Vertical bars 11-1, several of which are distributed with equal rounded corners within the housing 1. Threaded rods 11-2 are rotatably inserted into the vertical bars 11-1 via bearings. The threaded rods 11-2 have a two-section threaded structure. Two positioning blocks 11-3 are rotatably fitted onto the threaded rods 11-2 via threads. An adjusting handle 11-4 is rotatably inserted into the upper part of the housing 1 via a sealed bearing. The adjusting handle 11-4 is fixedly connected to the upper end of the threaded rods 11-2. Guide bars 15 are movably inserted into the guide grooves 14 on both sides of the positioning blocks 11-3. The guide bars 15 are fixedly installed within the vertical bars 11-1. The guide bars 15 provide guidance for the up-and-down movement of the positioning blocks 11-3 within the vertical bars 11-1, thereby improving the stability of the positioning blocks 11-3.
[0034] Abutment rod 11-5, comprising several rods, is fixedly mounted on several limiting blocks 9. A spring 8 is movably sleeved on the abutment rod 11-5. One end of the abutment rod 11-5 is movably inserted into the vertical strip 11-1 and movably abuts against the positioning block 11-3. The limiting mechanism 11 can limit the limiting blocks 9, preventing the antifouling strip 2 from being affected by external forces such as waves for a long time, thus preventing the limiting blocks 9 from shifting and causing the locking block 5 to move out of the slot 6. The detachment further reduces the risk of the anti-fouling strip 2 falling off the housing 1. Gears 12 are fixedly sleeved on the upper ends of several threaded rods 11-2. A gear ring 13 is rotatably arranged inside the housing 1 through a bearing. Several gears 12 are meshed with the gear ring 13. Through the cooperation of gears 12 and gear ring 13, the linkage between several threaded rods 11-2 can be realized, thereby realizing the synchronous control of several abutment rods 11-5, effectively improving the disassembly and assembly efficiency of the anti-fouling strip 2.
[0035] When using this invention, first open the sealing cover at the top of the housing 1, then install the EXO water quality sensor inside the housing 1, with the sensor head passing through the bottom of the housing 1 to monitor water quality. Next, place the anti-fouling tape 2 against the outside of the housing 1, and connect the two ends of the tape 2 using the attraction between the permanent magnet 3 and the magnetic metal sheet 4. Insert the locking block 5 into the slot 6, then move the anti-fouling tape 2 and the locking block 5 downwards to lock the locking block 5 in the slot 6. The limiting block 9, under the influence of the rebound force applied by the spring 8, can abut against the limiting groove 10, achieving initial limiting of the locking block 5 in the slot 6. Then, rotate the adjusting handle 11-4. Adjusting the screw 11-4 drives the connected threaded rod 11-2 to rotate, and by using the meshing of gear 12 and gear ring 13, the synchronous rotation of several threaded rods 11-2 can be achieved. When the threaded rod 11-2 rotates, it can drive the positioning block 11-3 to move downward, so that the positioning block 11-3 and the end of the abutment rod 11-5 can move and abut against each other, thereby limiting the position of the abutment rod 11-5 and the limiting block 9, and finally limiting the locking block 5 in the locking groove 6, thus completing the installation of the antifouling strip 2 on the shell 1. During the water quality monitoring process, the shell 1 will float on the sea surface, and the antifouling strip 2 will be located at the waterline. The antifouling strip 2 can achieve slow release of antifouling agent in the seawater environment to prevent organisms from attaching at the waterline of the shell 1.
[0036] Compared with the prior art, the beneficial effects of this utility model are:
[0037] Antifouling strip 2 uses a blended matrix of polyvinyl alcohol and chitosan, loaded with natural antifouling agents, which slowly dissolve and release in the seawater environment, effectively inhibiting the attachment of marine organisms such as barnacles and algae. It is free of heavy metal pollution, meets environmental protection requirements, and is suitable for ecologically sensitive sea areas.
[0038] The anti-fouling strip 2 can be quickly closed by adsorption between the permanent magnet 3 and the magnetic metal sheet 4. Combined with the cooperation of the locking block 5, the locking groove 6, the limiting block 9 and the spring 8, the anti-fouling strip 2 can be fixed on the housing 1 by simply pressing and moving it downwards during installation.
[0039] The limiting mechanism 11 can limit the limiting block 9, preventing the anti-fouling strip 2 from being affected by external forces such as waves for a long time, causing the limiting block 9 to shift and the card block 5 to disengage from the card slot 6, thereby further reducing the risk of the anti-fouling strip 2 falling off the shell 1.
[0040] The tilt angle 17 can provide guidance during the process of the card block 5 being inserted into the card slot 6, which not only improves the ease of the card block 5 entering the card slot 6, but also makes the assembly of the anti-fouling strip 2 more convenient.
[0041] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
