Description

Technical Field

[0001] This application relates to the field of sensor technology, and in particular to a sensor device and a temperature-salt sensor chain. Background Technology

[0002] A temperature and salinity sensor chain is a marine observation device that consists of multiple temperature and salinity sensors installed on a chain according to different survey depth requirements, forming a survey system that can simultaneously measure the distribution gradient of temperature and salinity data at different depths in the ocean.

[0003] In related technologies, temperature and salinity sensors are usually tied to anchor chains with ropes, or welded or directly fixed to the edge of underwater platforms using simple brackets. Due to the high pressure, high salt spray corrosion, and strong ocean currents in the ocean, the temperature and salinity sensors are not easily fixed, and the ropes or brackets are prone to loosening, corrosion, or breakage. This can easily lead to the sensor falling off and being lost, or the sensor colliding with the anchor chain and being damaged, affecting the stability of data acquisition. Utility Model Content

[0038] In the description of this application, it should be understood that the terms "first," "second," etc., are used to describe various types of information, but these terms are not limited to them and are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0039] like Figures 1 to 5As shown, this application embodiment provides a sensor device for connection with an anchor chain 100. The sensor device includes a sensor 200 and a fixing device. The fixing device includes a fixing plate 10 and a clamping assembly 20. The fixing plate 10 has a first side 11 and a second side 12 disposed opposite to each other. The second side 12 is provided with mounting holes 13. The fixing plate 10 is connected to the anchor chain 100 through the mounting holes 13. The clamping assembly 20 includes a first clamping member 21, a second clamping member 22 and a locking structure 23. The first clamping member 21 is disposed on the first side 11, and the second clamping member 22 is disposed on the side of the first clamping member 21 away from the fixing plate 10. One end of the second clamping member 22 is rotatably connected to one end of the first clamping member 21, and the other end of the second clamping member 22 is detachably connected to the other end of the first clamping member 21 through the locking structure 23. A clamping hole 24 for clamping the sensor 200 is formed between the first clamping member 21 and the second clamping member 22.

[0040] In this embodiment, the fixing plate 10 has a first side 11 and a second side 12 disposed opposite to each other, the first side 11 and the second side 12 being the front and back sides of the fixing plate 10, respectively. For example, the first side 11 is the front side of the fixing plate 10, and the second side 12 is the back side of the fixing plate 10.

[0041] Based on the above technical solution, the clamping assembly 20 is disposed on the first side 11 of the fixing plate 10, and the mounting hole 13 is disposed on the second side 12 of the fixing plate 10. The clamping assembly 20 and the mounting hole 13 are respectively located on the front and back sides of the fixing plate 10. The second clamping member 22 is flipped over, and the sensor 200 is placed in the clamping hole 24 between the second clamping member 22 and the first clamping member 21. Then, the locking structure 23 is used to lock the second clamping member 22 and the first clamping member 21. The clamping force is adjusted according to the size of the sensor 200 to ensure that the clamping assembly 20 stably clamps the sensor 200, preventing the sensor 200 from falling off or being lost. The fixing plate 10 is connected to the anchor chain 100 through the mounting holes 13. The second side 12 of the fixing plate 10 is connected to the anchor chain 100. This arrangement separates the sensor 200 from the anchor chain 100. Under conditions such as strong ocean currents, the sensor 200 will not directly contact the anchor chain 100, thereby avoiding wear and tear on the sensor 200 and preventing damage to the sensor 200. This improves the stability and accuracy of ocean water data acquisition.

[0042] In this embodiment, sensor 200 includes a temperature and salinity sensor, but it may also include other types of sensors used to survey and measure ocean water data, such as pressure sensors for measuring underwater pressure, temperature sensors for measuring water temperature, flow velocity sensors for measuring water flow velocity, and so on.

[0043] In this embodiment, the fixing plate 10 is connected to the anchor chain 100 through mounting holes 13. This connection includes both a fixed connection and a loose connection. For example, bolts are passed through the connection holes of the anchor chain 100 and the mounting holes 13 of the fixing plate 10 to ensure a tight connection between the fixing plate 10 and the anchor chain 100. The connection between the fixing plate 10 and the anchor chain 100 also includes a loose connection. A loose connection means that there is a certain relative space for movement between the fixing plate 10 and the anchor chain 100, for example, through fasteners such as hooks or buckles; the two are not completely bound together.

[0044] In some embodiments, the first clamping member 21 can be mounted on the fixing plate 10 by fasteners such as screws or bolts.

[0045] In some embodiments, the second clamping member 22 can be rotatably connected to the first clamping member 21 through a rotatable structure such as a pin or a rotating shaft.

[0046] In some embodiments, such as Figure 6 As shown, the first clamping member 21 is provided with a first limiting groove 211 facing the second clamping member 22, and the second clamping member 22 is provided with a second limiting groove 221 facing the first clamping member 21; when the first clamping member 21 and the second clamping member 22 are clamped on the sensor 200, the first limiting groove 211 and the second limiting groove 221 form a clamping hole 24.

[0047] Specifically, the shape and size of the first limiting groove 211 and the second limiting groove 221 are not specifically limited. When the sensor 200 is placed in the clamping hole 24, the first limiting groove 211 and the second limiting groove 221 are attached to the outer wall of the sensor 200, thereby stably clamping the sensor 200 and ensuring that the sensor 200 is in a stable position in the clamping hole 24, preventing it from becoming loose and affecting its measurement.

[0048] In general, the sensor 200 has a cylindrical structure with a circular cross-section. The first limiting groove 211 and the second limiting groove 221 can both be semi-circular arc grooves of 180 degrees, or one of the first limiting groove 211 and the second limiting groove 221 can be a large arc groove with an arc angle greater than 180 degrees, and the other arc groove with an arc angle less than 180 degrees can be a small arc groove. Alternatively, neither the first limiting groove 211 nor the second limiting groove 221 can be an arc groove. The shape can be adjusted according to the applicability of the cross-sectional shape of the sensor 200. For example, if the cross-section of the sensor 200 is square, the clamping hole 24 can be a square hole. As long as the sensor 200 can be stably clamped, it is within the protection scope of this embodiment.

[0049] In some embodiments, such as Figure 2 As shown, the clamping assembly 20 also includes a first limiting ring 25; the first limiting ring 25 is adapted to the shape and size of the first limiting groove 211, the first limiting ring 25 is detachably sleeved in the first limiting groove 211, and the first limiting ring 25 is used to fasten the sensor 200.

[0050] Specifically, the first limiting ring 25 is an adapter ring and is adapted to the shape and size of the first limiting groove 211. The first limiting ring 25 is fitted inside the first limiting groove 211, which enhances the adaptability. Different types of sensors 200 have different outer diameters. If the outer diameter of the sensor 200 cannot be completely matched with the first limiting groove 211, the first limiting ring 25 is fitted inside the first limiting groove 211, so that the first limiting ring 25 fits tightly against the lower half of the sensor 200, improving the clamping tightness and preventing the sensor 200 from shifting or loosening in the clamping hole 24. On the other hand, if the first limiting ring 25 is worn or damaged, it can be removed from the first limiting groove 211 for replacement without affecting the clamping function of the clamping assembly 20 for the sensor 200.

[0051] In some embodiments, the first limiting ring 25 is a silicone limiting ring, a rubber limiting ring, or a nylon limiting ring. Silicone and rubber are soft and elastic, preventing scratches, compression, or other damage to the outer wall of the sensor 200 when in contact with it. Nylon has good wear resistance and is not easily worn, maintaining a good fit with the outer wall of the sensor 200. Its relatively smooth surface also reduces friction with the outer wall of the sensor 200, lowering the risk of wear and extending the sensor's lifespan.

[0052] In some embodiments, such as Figure 2 As shown, the clamping assembly 20 also includes a second limiting ring 26; the shape and size of the second limiting groove 221 are adapted to the second limiting groove 221, and the second limiting ring 26 is detachably sleeved in the second limiting groove 221. The second limiting ring 26 is used to fasten the sensor 200.

[0053] Specifically, the second limiting ring 26 is an adapter ring, and its shape and size are adapted to the second limiting groove 221. The second limiting ring 26 is fitted inside the second limiting groove 221, which enhances the adaptability. Different types of sensors 200 have different outer diameters. If the outer diameter of the sensor 200 cannot be completely matched with the second limiting groove 221, the first limiting ring 25 is fitted inside the second limiting groove 221, so that the second limiting ring 26 fits tightly against the upper part of the sensor 200, improving the clamping tightness and preventing the sensor 200 from shifting or loosening in the clamping hole 24. On the other hand, if the second limiting ring 26 is worn or damaged, it can be removed from the second limiting groove 221 for replacement without affecting the clamping function of the clamping assembly 20 for clamping the sensor 200.

[0054] In this embodiment, the hole formed by the second limiting ring 26 and the first limiting ring 25 is adapted to the shape and size of the clamping hole 24.

[0055] In some embodiments, such as Figure 6 As shown, the locking structure 23 includes a screw 231 and a nut 232. The second clamping member 22 is provided with a mounting groove 222. One end of the screw 231 is rotatably connected to the first clamping member 21, and the other end of the screw 231 passes through the mounting groove 222 and is connected to the nut 232 outside the mounting groove 222, so that the second clamping member 22 is fastened to the first clamping member 21.

[0056] Specifically, when installing the sensor 200, the second clamping member 22 is flipped over and brought close to the first clamping member 21. The screw 231 is rotated so that it passes into the mounting groove 222 on the second clamping member 22. Then, the nut 232 is screwed onto the portion of the screw 231 that extends out of the mounting groove 222. By tightening the nut 232, the threaded engagement between the nut 232 and the screw 231 causes the nut 232 to move axially along the screw 231, thereby securing the second clamping member 22 and the first clamping member 21 together and tightly clamping the sensor 200 within the clamping hole 24. When removing the sensor 200, the nut 232 is rotated in the opposite direction to separate the second clamping member 22 from the first clamping member 21, allowing the sensor 200 to be removed.

[0057] In this embodiment, the second clamping member 22 and the first clamping member 21 are securely connected by the cooperation of the nut 232 and the screw 231. The structure is simple and easy to operate, allowing for quick installation and disassembly. The threaded connection has self-locking properties, preventing the second clamping member 22 and the first clamping member 21 from loosening after clamping the sensor 200, thus ensuring clamping stability. By controlling the tightness of the nut 232, the clamping force of the second clamping member 22 and the first clamping member 21 on the sensor 200 can be adjusted, avoiding excessive clamping force that could damage the sensor 200, or insufficient clamping force that could cause the sensor 200 to be unstable.

[0058] In some embodiments, such as Figure 2 and Figure 3 As shown, the fixing device also includes a first limiting member 30 and a second limiting member 40; the first limiting member 30 and the second limiting member 40 are spaced apart on the first side 11 along the length direction of the fixing plate 10, and are used to limit the opposite ends of the sensor 200.

[0059] Specifically, the first limiting member 30 and the second limiting member 40 may include structures such as limiting plates, limiting blocks, or limiting posts, and the structural form of the limiting members is not specifically limited. The first limiting member 30 and the second limiting member 40 are respectively installed on the first side 11 of the fixing plate 10. When the sensor 200 is placed on the fixing plate 10, the first limiting member 30 and the second limiting member 40 abut against the front and rear ends of the sensor 200 respectively, and then the clamping assembly 20 clamps the sensor 200. The two limiting members can prevent the sensor 200 from shifting or sliding along the length direction of the fixing plate 10, further improving the installation stability of the sensor 200. On the other hand, according to the position of the two limiting members, it is convenient to quickly place the sensor 200 on the clamping assembly 20, improve the installation efficiency, and play a role in preventing mistaken operation.

[0060] In some embodiments, the first limiting member 30 and the second limiting member 40 are integrally formed with the fixing plate 10 by injection molding.

[0061] In some embodiments, the first limiting member 30 and the second limiting member 40 are both detachably connected to the fixing plate 10 and are installed on the fixing plate 10 by fasteners such as bolts or screws. The distance between the first limiting member 30 and the second limiting member 40 can be adaptively adjusted according to the length of the sensor 200 so that the two limiting members play a limiting role and improve the applicability of the fixing device.

[0062] In some embodiments, such as Figure 5 and Figure 7 As shown, the fixing device also includes a first locking member 50, which passes through the mounting hole 13 and the anchor chain 100 to connect the fixing plate 10 to the anchor chain 100.

[0063] Specifically, the first locking element 50 may include a rope connector or a metal buckle, etc. When connecting the fixing plate 10 to the anchor chain 100, first determine the appropriate mounting hole 13 on the fixing plate 10, and align the mounting hole 13 with the connection part of the anchor chain 100. If the first locking element 50 is a rope connector, pass the rope through the mounting hole 13 and the corresponding hole of the anchor chain 100, and then fix it by knotting or fastening the rope, tightening the rope to make the fixing plate 10 and the anchor chain 100 tightly connected; if the first locking element 50 is a metal buckle, pass the metal buckle through the mounting hole 13 and the corresponding hole of the anchor chain 100, and then use the structural characteristics of the metal buckle itself, such as snap-fit ​​or bolt connection, to lock the metal buckle, thereby completing the loose connection between the fixing plate 10 and the anchor chain 100. During disassembly, untie the rope or open the metal buckle to quickly separate the fixing plate 10 and the anchor chain 100.

[0064] In this embodiment, the fixing plate 10 and the anchor chain 100 are connected by the first locking fastener 50 through the mounting hole 13 and the anchor chain 100. The structure is simple and easy to operate, and installation and disassembly can be completed quickly. This facilitates the installation, maintenance or replacement of the sensor 200. This connection method can ensure a reliable connection between the fixing plate 10 and the anchor chain 100, and improve the stability and accuracy of water data acquisition.

[0065] In some embodiments, such as Figure 4 As shown, the second side 12 is provided with a plurality of mounting holes 13, which are arranged at intervals along the length of the fixing plate 10.

[0066] Specifically, during actual installation, a suitable hole position is selected from multiple mounting holes 13 based on factors such as the structure and connection position of other components. The first locking element 50 (such as bolt, pin, lock, etc.) is passed through the selected mounting hole 13 to connect and fix it with the corresponding holes or structures on other components, thereby further enhancing the connection stability between the fixing plate 10 and the anchor chain 100.

[0067] In some embodiments, such as Figure 4 As shown, multiple support ears 14 are installed on the second side 12, and each support ear 14 has a mounting hole 13. The support ears 14 can increase the structural thickness and strength of the mounting hole 13, so that the mounting hole 13 can better withstand the tensile force generated during connection, reduce the risk of cracks, deformation or even breakage at the mounting hole 13, and improve the reliability of connection.

[0068] In some embodiments, the support ear 14 extends in a direction perpendicular to the second side 12, providing a more stable point of force, facilitating installation and disassembly with tools, thereby facilitating the connection between the mounting hole 13 and the anchor chain 100, and improving installation and maintenance efficiency.

[0069] In some embodiments, such as Figure 4 As shown, reinforcing ribs are formed on opposite sides of the support ear 14 to enhance the structural strength and rigidity of the support ear 14.

[0070] In some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, a tethering structure 60 is provided on the first side 11, and an electrical cable 300 is connected to the sensor 200; the fixing device also includes a second locking member 70, which passes through the tethering structure 60 and the electrical cable 300.

[0071] Specifically, the sensor 200 is connected to the control equipment on the water surface via an electrical cable 300 to provide power and communication functions. To prevent the electrical cable 300 from swaying and affecting the installation stability of the sensor 200, the second locking fastener 70 is used to secure the mooring structure 60 and the electrical cable 300, thus fixing the electrical cable 300 to the mooring structure 60 and preventing it from swaying.

[0072] In some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, multiple tethering structures 60 are provided at different positions on the first side 11. The fixing device includes multiple second locking parts 70. Each second locking part 70 is respectively bound to a different tethering structure 60 to bind multiple positions of the electrical cable 300, further preventing the electrical cable 300 from shaking.

[0073] In some embodiments, the second locking member 70 may include a rope connector or a metal buckle. During installation, the second locking member 70 is passed through a hole in the mooring structure 60, passes through or wraps around the electrical cable 300, and is secured by knotting or locking to connect the electrical cable 300 to the mooring structure 60. This fixes the electrical cable 300 to the sensor device, preventing it from swinging or tangling in the complex underwater environment due to water flow impact, equipment shaking, etc., thus ensuring the stability of power supply and communication.

[0074] like Figure 7 As shown, a second aspect of this application provides a temperature and salinity sensor chain, including an anchor chain 100 and a sensor device connected to the anchor chain 100.

[0075] Specifically, the sensor 200 is clamped onto the first side 11 of the fixing plate 10 by the clamping assembly 20, and connected to the anchor chain 100 through the mounting holes 13 of the fixing plate 10. The second side 12 of the fixing plate 10 is also connected to the anchor chain 100, thereby separating the sensor 200 from the anchor chain 100. Under conditions such as strong ocean currents, the sensor 200 will not directly contact the anchor chain 100, thus avoiding wear and tear on the sensor 200 and preventing damage to the sensor 200. This improves the stability and accuracy of ocean water data acquisition.

[0076] In some embodiments, the temperature and salinity sensor chain includes multiple fixing devices and multiple sensors 200, with each sensor 200 mounted on a corresponding fixing device. Each fixing device is connected to a different position on the anchor chain 100 to form a chain-like sensor assembly, thereby forming a survey system capable of simultaneously measuring the temperature and salinity data distribution gradient at different depths in the ocean.

[0077] In some embodiments, such as Figure 7 As shown, the temperature and salinity sensor chain also includes a traction rope 400, and the sensor device also includes a positioning block 201. The positioning block 201 is detachably connected to the housing of the sensor 200, and a through hole is formed between the positioning block 201 and the housing of the sensor 200. The traction rope 400 passes through the through hole to connect the sensor device and the traction rope 400 together in series. Using the above connection method, multiple sensor devices are connected in series sequentially using the traction rope 400. After completing the water body survey, the connection between the sensor device and the anchor chain 100 is released, and then all sensor devices are pulled to the water surface using the traction rope 400. The positioning block 201 is then removed, disconnecting the sensor device from the traction rope 400, thereby disassembling the sensor device.

[0078] In some embodiments, the second locking member 70 is also used to bind the traction rope 400 to the tethering structure 60, further improving the installation stability of the sensor device.

[0079] In some embodiments, the positioning block 201 and the housing of the sensor 200 can be connected by fasteners such as screws or bolts.

[0080] It should be understood that the term "and / or" as used in this specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes such combinations. It should be noted that, herein, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system.
