Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0042] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0043] See also Figure 1 and Fig.10 As shown, the water surface oil pollution detection device 100 provided by the embodiment of the present invention is used to be placed on the water surface to detect whether there is oil pollution on the water surface. The water surface oil pollution detection device 100 can be specifically connected to the monitoring center 200 or the communication terminal for communication, so that an alarm signal can be sent to the monitoring center 200 or the communication terminal in time after the oil pollution is detected. When the water surface oil pollution detection device 100 is in use, the bottom is immersed in water and the top is exposed on the water surface. The water surface oil pollution detection device 100 can be specifically suspended on the water surface by a bracket or a buoy; or it can be hung on the water surface by a communication line. In specific applications, it can be flexibly set according to actual conditions.

[0044] like Figure 1-3As shown, in this embodiment, the water surface oil pollution detection device 100 includes a housing assembly 110, a support member 120, a detection membrane 130, a communication assembly 140, and a trigger assembly 150. The housing assembly 110 has a first end 1111 and a second end 1121 that are arranged opposite to each other. The first end 1111 is specifically the bottom end of the housing assembly 110, and the second end 1121 is specifically the top end of the housing assembly 110. The support member 120 is installed in the housing assembly 110 and is arranged near the first end 1111. The housing assembly 110 is provided with a lateral opening 1112 at the side near the first end 1111. The detection membrane 130 is a membrane that dissolves when it encounters oil. The detection membrane 130 is installed on the support member 120 and is arranged opposite to the lateral opening 1112. The side opening 1112 is mainly used to ensure that when the bottom of the water surface oil pollution detection device 100 is immersed in water, the water can keep in contact with the detection membrane 130 through the side opening 1112, so that the detection membrane 130 can detect whether there is oil pollution on the water surface. The communication component 140 is connected to the housing component 110 and extends from the second end 1121 toward the inside of the housing component 110; the trigger component 150 is arranged in the housing component 110 and between the detection membrane 130 and the communication component 140, so as to send a trigger alarm signal to the communication component 140 after the detection membrane 130 is dissolved. When the water surface oil pollution detection device 100 is in use, the first end 1111 will be immersed in water, and the side opening 1112 and the detection membrane 130 can be completely immersed in water, or only partially immersed in water, as long as the detection membrane 130 can be in contact with the water surface; the second end 1121 is exposed on the water surface to prevent water from entering the housing component 110 from the top of the housing component 110 to affect the normal use of the communication component 140.

[0045] In a specific application, when there is oil on the water surface, the detection membrane 130 will produce a chemical reaction and dissolve and break when it encounters oil; after the detection membrane 130 dissolves and breaks, the trigger component 150 will send a trigger alarm signal to the communication component 140, and the communication component 140 will send an alarm signal to the monitoring center 200 or the communication terminal, thereby realizing unmanned online monitoring of oil on the water surface. In addition, the embodiment of the present invention uses a detection membrane 130 that dissolves when it encounters oil to detect oil, which has a simple structure and low cost, and the detection membrane 130 does not consume electricity during detection, which is conducive to the long-term continuous operation of the water surface oil detection device 100.

[0046] The detection membrane 130 is a fat-soluble membrane, which can dissolve quickly after encountering oil stains. The detection membrane 130 can be specifically a membrane made of organic polymer materials.

[0047] In this embodiment, the detection film 130 is a disposable film, and the detection film 130 will be dissolved after detecting the oil stain. At this time, only one detection film 130 needs to be replaced.

[0048] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the housing assembly 110 includes a protective shell 111 and an outer shell 112, one end of the outer shell 112 is connected to one end of the protective shell 111, the end of the protective shell 111 away from the outer shell 112 is a first end 1111, the end of the outer shell 112 away from the protective shell 111 is a second end 1121, the outer shell 112 also has a third end 1122 facing the protective shell 111, and the protective shell 111 also has a fourth end 1113 facing the outer shell 112. The lateral opening 1112 is provided on the side of the protective shell 111, the support member 120, the detection film 130 and the trigger assembly 150 are all accommodated in the protective shell 111, and the communication assembly 140 extends from the second end 1121 into the outer shell 112. Here, the shell assembly 110 is divided into two parts: a protective shell 111 and an outer shell 112. On the one hand, it can facilitate the installation of the support 120, the detection membrane 130, the trigger assembly 150 and the communication assembly 140. On the other hand, the communication assembly 140 and the detection membrane 130 are separately installed in different shells, which can help better protect the communication assembly 140 from being corroded by water.

[0049] like Figure 5 As shown, in this embodiment, the protective shell 111 has a hollow inner hole 1114 extending from the first end 1111 toward the third end 1122 , and the lateral opening 1112 is connected to the hollow inner hole 1114 .

[0050] In this embodiment, the outer contour of the protective shell 111 is cylindrical, and the hollow inner hole 1114 is a cylindrical hole. Of course, in specific applications, the outer contour shape of the protective shell 111 and the shape of the hollow inner hole 1114 are not limited thereto, and can also be designed as a polygon, an elliptical cylinder, or a cone.

[0051] In this embodiment, two lateral openings 1112 are provided, and the two lateral openings 1112 are symmetrically arranged on both sides of the protective shell 111, and the detection membrane 130 is located between the two lateral openings 1112. In this way, the detection membrane 130 can be better in contact with water while ensuring the structural strength of the protective shell 111. Of course, in specific applications, the number and distribution of the lateral openings 1112 are not limited thereto. For example, the number of the lateral openings 1112 can also be one or more than three. When there are more than three lateral openings 1112, the multiple lateral openings 1112 are spaced and distributed on the side of the protective shell 111 along the circumferential direction.

[0052] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in this embodiment, the housing 112 has a first concave hole 1123 that is concavely arranged from the third end 1122 toward the second end 1121 and a second concave hole 1124 that is concavely arranged from the second end 1121 toward the third end 1122 and is not connected to the first concave hole 1123. One end of the trigger component 150 is inserted into the first concave hole 1123, and the communication component 140 extends from the second end 1121 into the second concave hole 1124. The first concave hole 1123 is mainly used to achieve the connection between the trigger component 150 and the housing 112; the second concave hole 1124 is mainly used to accommodate and protect the communication component 140. Here, the first concave hole 1123 and the second concave hole 1124 are both set as blind holes, and the first concave hole 1123 and the second concave hole 1124 are not connected, which is conducive to better preventing water from entering the second concave hole 1124 from the bottom of the housing 112 to affect the communication component 140.

[0053] In this embodiment, the outer shell 112 is detachably connected to the protective shell 111, that is, the third end 1122 is detachably connected to the fourth end 1113, which facilitates the subsequent disassembly and maintenance of the water surface oil pollution detection device 100. The detachable connection between the outer shell 112 and the protective shell 111 can be: the third end 1122 is inserted into the fourth end 1113 and then locked by bolts or screws.

[0054] like Figure 2-7 As shown, in this embodiment, the housing 112 includes a main housing portion 1125, a first connection portion 1126 provided at one end of the main housing portion 1125, and a second connection portion 1127 provided at the other end of the main housing portion 1125, the third end portion 1122 is provided at the first connection portion 1126, the second end portion 1121 is provided at the second connection portion 1127, the first connection portion 1126 is mainly used to connect with the trigger component 150, and the second connection portion 1127 is mainly used to connect with the communication component 140. The side of the first connection portion 1126 is provided with a plurality of first connection holes 1128, and the side of the protective shell 111 is provided with a plurality of second connection holes 1115 corresponding to the first connection holes 1128. The first connection portion 1126 is inserted into the hollow inner hole 1114, and is locked by bolts or screws penetrating and connecting the first connection holes 1128 and the second connection holes 1115, so that it is easy to install and reliable in fastening.

[0055] The outer diameter of the first connection portion 1126 is smaller than the outer diameter of the main shell portion 1125, and the outer diameter of the second connection portion 1127 is larger than the outer diameter of the main shell portion 1125. The first recessed hole 1123 extends from the end surface of the first connection portion 1126 toward the main shell portion 1125; the second recessed hole 1124 extends from the end surface of the second connection portion 1127 into the main shell portion 1125. Here, the first connection portion 1126 is configured to have an outer diameter smaller than the outer diameter of the main shell portion 1125, so as to limit the depth of the outer shell 112 inserted into the protective shell 111. Of course, in specific applications, the structure of the outer shell 112 is not limited thereto. For example, the outer shell 112 can also be designed to have an outer contour with a uniform cross-section.

[0056] like Figure 3 and Figure 7 As shown, in the present embodiment, a third recessed hole 1129 is further recessed on the end face of the first connecting portion 1126, the first recessed hole 1123 is centrally arranged on the end face of the first connecting portion 1126, the third recessed hole 1129 is arranged close to the outer edge of the end of the first connecting portion 1126, and one end of the support member 120 is inserted into the third recessed hole 1129 and is locked by bolts, screws or pins.

[0057] like Figure 2-4 As shown, in this embodiment, the communication component 140 includes an electromagnetic switch 141 and a communication component 142 electrically connected to the electromagnetic switch 141. The electromagnetic switch 141 is used to sense the trigger alarm signal of the trigger component 150 and control the communication component 142 to send an alarm signal outward.

[0058] In this embodiment, the communication component 142 includes a circuit board 1421 and a communication connector 1422. The circuit board 1421 is installed in the housing assembly 110 and is arranged near the second end 1121; the communication connector 1422 is installed at the second end 1121; the electromagnetic switch 141 and the communication connector 1422 are respectively connected to the circuit board 1421. The circuit board 1421 and the electromagnetic switch 141 are both accommodated in the second recessed hole 1124 of the housing 112. The communication connector 1422 can be connected to the end of the protective shell 111 by threaded connection or interference fit connection, and seal the opening of the second recessed hole 1124 of the protective shell 111, so as to better prevent water from affecting the circuit board 1421. When used, a signal output port and a communicator can be connected to the communication connector 1422.

[0059] The electromagnetic switch 141 is mounted on the circuit board 1421 , which, on the one hand, facilitates better electrical connection between the electromagnetic switch 141 and the circuit board 1421 ; on the other hand, it is beneficial to improve the compactness of the structure.

[0060] In this embodiment, the electromagnetic switch 141 is installed at the end of the circuit board 1421 facing the trigger assembly 150 , so that the trigger assembly 150 can better trigger the electromagnetic switch 141 to work.

[0061] The circuit board 1421 can be specifically locked and positioned in the housing assembly 110 by connecting with the communication connector 1422 .

[0062] In this embodiment, the communication component 142 also includes a battery 1423, and the battery 1423 is connected to the circuit board 1421. The battery 1423 is used for the electromagnetic switch 141 to provide power for the circuit board 1421 and the communication connector 1422 after being triggered by the magnet 153 of the trigger component 150. The detection membrane 130 does not consume electricity during detection, and only needs electricity when the communication component 142 sends an alarm signal. That is, the water surface oil pollution detection device 100 provided in the embodiment of the present invention consumes electricity when the communication component 142 sends an alarm signal to the outside, and does not consume electricity during normal monitoring. Therefore, the water surface oil pollution detection device 100 can adapt to long-term maintenance-free operation. Of course, in specific applications, as an alternative implementation scheme, the communication component 142 can also be powered by an external power supply.

[0063] In this embodiment, the battery 1423 is a lithium thionyl chloride battery, which is a disposable lithium thionyl chloride battery. The annual self-discharge current of the battery 1423 is less than 1%, and the storage life can reach more than 10 years. Of course, in specific applications, the battery 1423 can also use other forms of batteries, and can also use rechargeable batteries.

[0064] A battery mounting slot 1424 is provided on the circuit board 1421, and the battery 1423 is installed in the battery mounting slot 1424. This can, on the one hand, facilitate the electrical connection between the battery 1423 and the circuit board 1421; on the other hand, it can help improve the reliability of the positioning of the battery 1423; on the other hand, it can also help improve the structural compactness of the water surface oil pollution detection device 100, thereby facilitating the miniaturization design of the water surface oil pollution detection device 100.

[0065] like Figure 3 and Fig.10As shown, a data acquisition unit 1425 and a positioning unit 1426 are provided on the circuit board 1421. The positioning unit 1426 and the electromagnetic switch 141 are respectively connected to the battery 1423, and the electromagnetic switch 141 is connected between the battery 1423 and the data acquisition unit 1425. The data acquisition unit 1425 and the positioning unit 1426 are respectively connected to the communication connector 1422. The positioning unit 1426 can be a GPS positioning unit 1426 or a Beidou positioning unit 1426. When the detection film 130 is chemically reacted with oil, dissolved and broken, the electromagnetic switch 141 is triggered to work to conduct the communication circuit on the circuit board 1421. The positioning unit 1426 sends the positioning data to the monitoring center 200 or the communication terminal to indicate where the oil is leaking. At the same time, the data can also be transmitted to the monitoring center 200 or the communication terminal for analysis through the data acquisition unit 1425.

[0066] In this embodiment, the communication connector 1422 is a waterproof five-core connector. Of course, the form of the communication connector 1422 is not limited to this.

[0067] like Figure 2-4 As shown, in this embodiment, the trigger assembly 150 includes a limiting member 151, a pull rod 152, a magnet 153 and an elastic member 154. The limiting member 151 is installed in the shell assembly 110; the pull rod 152 is slidably arranged to connect the limiting member 151, and one end of the pull rod 152 extends toward the electromagnetic switch 141, and the other end extends toward the first end 1111 and is connected to the detection film 130; the magnet 153 is connected to the end of the pull rod 152 close to the electromagnetic switch 141; the elastic member 154 is elastically compressed between the limiting member 151 and the magnet 153. Before the oil stain is detected, the two ends of the detection membrane 130 are respectively connected to the support member 120 and the pull rod 152, and the elastic member 154 is compressed between the magnet 153 and the limiting member 151 under the pulling force of the detection membrane 130 on the pull rod 152; when the detection membrane 130 is dissolved and broken by the oil, the pulling force of the detection membrane 130 on the pull rod 152 disappears, and the elastic restoring force of the elastic member 154 drives the magnet 153 to move away from the detection membrane 130, and the electromagnetic switch 141 senses that the magnet 153 is approaching it, and then controls the battery 1423 to supply power to the circuit board 1421 and the communication connector 1422, and sends the positioning data to the monitoring center 200 or the communication terminal to indicate where the oil is leaking.

[0068] like Figure 3 , Figure 4 and Figure 8As shown, in this embodiment, the limiting component 151 includes a limiting stopper 1511 and a sleeve 1512, one end of which is connected to the limiting stopper 1511 and extends from the limiting stopper 1511 toward the electromagnetic switch 141. One end of the pull rod 152 passes through the limiting stopper 1511 and extends into the sleeve 1512. The magnet 153 and the elastic member 154 are both located in the sleeve 1512, and the two ends of the elastic member 154 respectively abut the limiting stopper 1511 and the magnet 153.

[0069] In this embodiment, the setting of the limit stopper 1511 is mainly used for the elastic member 154 to resist the limit; the setting of the sleeve 1512 is used to protect the elastic member 154 and the magnet 153 on the one hand; on the other hand, it is used to realize the connection and fixation of the limit member 151 in the shell assembly 110. Specifically, in this embodiment, the fixing method of the limit member 151 in the shell assembly 110 is: the end of the sleeve 1512 away from the limit stopper 1511 is penetrated by the first recessed hole 1123 connected to the shell 112; the penetration connection method of the sleeve 1512 and the first recessed hole 1123 can be a threaded connection or an interference fit connection, or the sleeve 1512 is penetrated in the first recessed hole 1123 and then locked by a fastener. Of course, in a specific application, as an alternative embodiment, the fixing method of the limit member 151 in the shell assembly 110 can also be that the limit stopper 1511 is connected to the protective shell 111 or the support member 120.

[0070] In this embodiment, the limit stopper 1511 and the sleeve 1512 are two separately manufactured components; of course, in a specific application, as an alternative embodiment, the limit stopper 1511 and the sleeve 1512 can also be designed to be manufactured in one piece.

[0071] In this embodiment, the connection method of the limit stopper 1511 and the sleeve 1512 is as follows: a countersunk hole 1501 is provided on the side of the limit stopper 1511 facing the sleeve 1512, and one end of the sleeve 1512 is penetrated to connect the countersunk hole 1501. The penetration connection method of the sleeve 1512 and the countersunk hole 1501 can be a threaded connection or an interference fit connection, or the sleeve 1512 is penetrated in the countersunk hole 1501 and then locked by a fastener.

[0072] A through hole 1502 for the pull rod 152 to pass through is provided on the side of the position-limiting stopper 1511 facing away from the sleeve 1512. The aperture of the through hole 1502 is smaller than the aperture of the counterbore 1501, and the through hole 1502 extends to communicate with the counterbore 1501. The end of the pull rod 152 extending into the position-limiting member 151 passes through the through hole 1502 and the counterbore 1501 in sequence and finally extends into the sleeve 1512.

[0073] In this embodiment, the stopper 1511 is a hexagonal nut with a countersunk hole 1501 and a through hole 1502, which has a simple structure and is easy to manufacture and install. Of course, in specific applications, the structure of the stopper 1511 is not limited to this.

[0074] like Figure 2 , Figure 4 , Fig. 9 As shown, the pull rod 152 includes a first axially extending rod body 1521 extending along the axial direction of the shell assembly 110, a first radially extending rod body 1522 extending along the radial direction of the shell assembly 110, and a bent connecting rod body 1523 bent and connected to the first axially extending rod body 1521 and the first radially extending rod body 1522. The first axially extending rod body 1521 can be slidably penetrated into the connection limiting member 151 and connected to the magnet 153. The first radially extending rod body 1522 and the bent connecting rod body 1523 are both located between the limiting member 151 and the detection membrane 130, and the first radially extending rod body 1522 is connected to the detection membrane 130. The setting of the first axially extending rod body 1521 is mainly used to realize the connection between the pull rod 152 and the magnet 153; the setting of the first radially extending rod body 1522 is mainly used to realize the connection between the pull rod 152 and the detection membrane 130; the setting of the bent connecting rod body 1523 is mainly used to limit the distance that the pull rod 152 moves through the limiting member 151 toward the communication component 140.

[0075] like Figure 4 , Figure 7 and Fig. 9 As shown, in this embodiment, the support member 120 includes a second axially extending rod 121 spaced apart and parallel to the first axially extending rod 1521 and a second radially extending rod 122 spaced apart and parallel to the first radially extending rod 1522, the second radially extending rod 122 is connected to the end of the second axially extending rod 121 close to the first end 1111, and the two ends of the detection film 130 are respectively connected to the first radially extending rod 1522 and the second radially extending rod 122. The second axially extending rod 121 is mainly used to achieve the connection between the support member 120 and the housing assembly 110; specifically, the second axially extending rod 121 is spaced apart and arranged beside the sleeve 1512, and the end of the second axially extending rod 121 away from the second radially extending rod 122 is inserted into the third recessed hole 1129 of the housing 112 and is locked by fasteners such as bolts, screws, rivets or pins, so as to achieve the locking and positioning of the support member 120. The second radially extending rod 122 is mainly used to realize the connection between the support member 120 and the detection membrane 130. In this embodiment, the support member 120 is an L-shaped rod, which has a simple structure and is easy to manufacture, shape and install.

[0076] Before the oil stain is detected, the detection membrane 130 exerts a pulling force on the pull rod 152 toward the second radially extending rod body 122, and the magnet 153 is fixedly connected to the pull rod 152, so the magnet 153 is also subjected to a pulling force toward the second radially extending rod body 122, thereby driving the elastic member 154 to produce a certain degree of compression deformation; when the detection membrane 130 is dissolved and broken by the oil, the pulling force of the detection membrane 130 on the pull rod 152 disappears, and the elastic restoring force of the elastic member 154 drives the magnet 153 and the pull rod 152 to move away from the second radially extending rod body 122, so that the magnet 153 can trigger the electromagnetic switch 141 to work.

[0077] The two ends of the detection film 130 can be connected to the first radially extending rod body 1522 and the second radially extending rod body 122 respectively by bonding, which is convenient for installation.

[0078] In this embodiment, the elastic member 154 is a spring sleeved outside the first axially extending rod 1521, and the spring can be a cylindrical coil spring. Here, the elastic member 154 is sleeved on the pull rod 152 to prevent the elastic member 154 from distorting and stretching, thereby extending the service life of the elastic member 154 and facilitating the reliability of the elastic member 154 driving the magnet 153 to move. Of course, in specific applications, the elastic member 154 can also be replaced by other elastic elements, such as a spring sheet or an elastic hose.

[0079] The water surface oil pollution detection device 100 provided in the embodiment of the present invention is a device for detecting oil pollution in the water environment. When oil pollution leaks in the water body, the water surface oil pollution detection device detects the oil pollution, activates an alarm, and transmits data to the monitoring center 200 or a communication terminal, so as to timely know the water environment status. Specifically, the working principle of the water surface oil pollution detection device 100 provided in the embodiment of the present invention is: the water surface oil pollution detection device 100 is installed on the water surface by a bracket or a buoy or a communication line hanging method, and the bottom of the water surface oil pollution detection device 100 is immersed in water to ensure that the detection membrane 130 can contact with water. When there is oil on the water surface, the detection membrane 130 dissolves and breaks when it encounters oil, the pulling force of the detection membrane 130 on the pull rod 152 disappears, and the elastic restoring force of the elastic part 154 drives the magnet 153 to move away from the detection membrane 130. The electromagnetic switch 141 senses that the magnet 153 is approaching it, and controls the battery 1423 to supply power to the circuit board 1421 and the communication connector 1422, and sends an alarm signal to the monitoring center 200 or the communication terminal to indicate where the oil leak is, thereby realizing automatic detection of the oil pollution condition in the water body in an unmanned environment.

[0080] The water surface oil pollution detection device 100 provided in the embodiment of the present invention adopts the cooperation of the detection membrane 130, the trigger component 150, and the communication element to detect various oil pollutions on the water surface in real time; and it has a simple structure and low cost, can realize long-term detection of oil pollution conditions in water bodies in an unmanned environment, can provide effective intelligence for water environment monitoring, and can play an important role in aquaculture, shipping, tourism and other industries.
