Description

A scanning oil spill monitoring device Technical Field

[0001] The present invention relates to the technical field of water surface oil pollution monitoring equipment, in particular to a scanning type oil spill monitoring equipment. Background Art

[0002] Pollution caused by the entry of petroleum and its products into the marine environment during extraction, refining, storage, transportation, and use. Oily wastewater, the discharge of ballast and tank washing water from ships at sea, tanker disasters, leaks from pipelines, and offshore oil production are all major sources of marine oil pollution. It is estimated that approximately 6 million tons of oil enter the oceans annually through various channels worldwide.

[0003] Therefore, it is necessary to conduct oil pollution monitoring first and then deal with the oil pollution; oil pollution monitoring is to use special instruments to identify or analyze whether there is oil pollution on the water surface, and then send early warning information to production personnel. For example, the applicant in this case provided the following solution in the utility model document with publication number CN213337347U: a floating surface oil pollution monitoring system, including an oil pollution monitor, a battery, a solar panel and a wireless data transmission device arranged on a floating platform; the floating platform consists of a box, a square glass plate and four floats; the square glass plate is sealed and fixed at the bottom opening of the box by a seal, closing the box into a sealed box structure; the four floats are respectively fixed at the four corners of the bottom of the box; the oil pollution monitor consists of an ultraviolet laser and a spectrum analyzer, both of which are arranged on the square glass plate, and the solar panel is arranged on the top surface and / or side wall of the box; the solar panel is connected to the battery to enable the battery to continuously power each electrical component; the wireless data transmission device is connected to the spectrum analyzer; the system has a simple structure, and has the advantages of low cost and no need for power connection. It can meet the oil pollution monitoring and early warning needs in remote and sensitive waters, and has the potential for large-scale promotion.

[0004] However, the aforementioned floating surface oil pollution monitoring system has limitations in some cases, such as in areas with strong winds and waves (there is a risk of capsizing), or in narrow river areas (there is a risk of collision with the hull).

[0005] In addition, the scanning monitoring equipment in the existing technology is not suitable for oil spill monitoring at the seaside. First, the scanning structure has many connection points, which is easily corroded and damaged when installed at the seaside, and has a short service life. Second, it is installed at the seaside and exposed to direct sunlight for a long time, which will further reduce the service life of internal components.

[0006] Therefore, in areas with strong winds and waves or where ships pass through narrow areas, it is necessary to design an oil spill monitoring device that can prevent excessive winds and waves, reduce the space occupied by the river surface, and have a certain scanning range.

[0007] Summary of the Invention

[0013] When the servo motor drives the oil pollution monitor to perform pendulum motion, the detection end of the oil pollution monitor faces the transparent structure, and the swing trajectory of the straight line where the axis of the oil pollution monitor is located at the bottom of the sealed housing is always within the range of the transparent structure;

[0014] The servo motor can control the oil pollution monitor to hover at any point of the pendulum movement, and the hovering time is adapted to or exceeds the time it takes for the oil pollution monitor to emit and receive light once.

[0022] The protrusion is embedded in the strip chute, and the servo motor drives the protrusion of the circular plate to perform circular motion. The protrusion is used to convert the lateral displacement and vertical displacement of its own circular motion process into the lateral swing of the swing plate and the longitudinal relative sliding between the swing plate and the strip chute.

[0023] Preferably, a counterweight is provided on the balance block, and the weight of the counterweight matches the weight of the oil pollution monitor.

[0025] Preferably, an engaging structure is provided between the pressing plate and the surface of the secondary step, the engaging structure comprising a sealing rubber ring embedded in the secondary step, and a rubber column for embedding in the sealing rubber ring is provided on the pressing plate.

[0031] The present invention sets a sealed shell outside the oil pollution monitor to play the role of corrosion prevention and dust prevention, which can extend the service life of the oil pollution monitor and prevent the oil pollution monitor from being directly exposed to the sun, further extending the service life of the equipment; but the oil pollution monitor is set at the seaside and will be directly exposed to the sun, and the oil pollution monitor is sealed, which will cause the air pressure in the sealed shell to increase, and there is a risk of deformation and cracking of the sealed shell, and it is easy to cause pressure on some sealing structures of the oil pollution monitor. In winter or at night, the temperature drops, which will cause the air pressure inside the sealed shell to drop, and the low air pressure will affect the electrical components. Therefore, the buckle assembly is further provided to buffer the thermal expansion and contraction of the air in the space, so that the air pressure in the sealed shell can be balanced and the fluctuation will not be too large.

DETAILED DESCRIPTION

[0041] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0042] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0043] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0046] In general, the present invention aims to provide a scanning oil spill monitoring device to improve the problems in the existing technology that surface oil spill monitoring equipment is difficult to cope with excessive wind and waves and occupies too much space, and can complement and cooperate with surface oil spill monitoring equipment to improve the monitoring system and reduce monitoring blind spots.

[0047] It includes:

[0048] A sealed housing 2 is erected on the shore (generally via columns 1, which are generally made of metal and, in some embodiments, are 7-8 meters long. In other embodiments, they can also be concrete columns, but concrete columns require pre-filled holes, making metal columns easier to implement). At least a portion of the bottom of the sealed housing 2 is constructed as a transparent structure 9. In some embodiments, the transparent structure 9 is a glass plate. It is worth noting that increasing the usable area of ​​the transparent structure 9 will correspondingly reduce the usable area of ​​the sealed housing 2, thereby weakening the overall rigidity and load-bearing capacity of the sealed housing 2 to a certain extent. Therefore, the area of ​​the transparent structure 9 cannot be increased indefinitely.

[0049] The oil pollution monitor 3 is rotatably disposed in the sealed housing 2 and is similar to or identical to the oil pollution monitors in the prior art, having light emitting and receiving capabilities. However, it takes a certain amount of time for the oil pollution monitor 3 to emit a light α, reflect the light α on the detection water surface, and then receive the reflected light α. Therefore, in some embodiments, the oil pollution monitor 3 needs to hover for 1-3 seconds at each detection point. Specifically, in some embodiments, the middle portion of the oil pollution monitor 3 can be directly rotatably connected to the sealed housing 2 via a bearing. In other embodiments, other methods such as an arc guide rail can be used, so that the detection end (i.e., the lower end) of the oil pollution monitor can perform a pendulum motion. In some embodiments, considering the actual constraints of the sealed housing and other structures, the actual swing amplitude of the pendulum motion is generally plus or minus 30 degrees.

[0050] The servo motor 7 is used to provide rotational driving force and control the oil pollution monitor 3. In the present invention, control mainly includes controlling the direction of rotation, braking, and controlling the braking time. Specifically, in some embodiments, the output shaft of the servo motor 7 is directly rigidly connected to the rotation center of the oil pollution monitor 3. In other embodiments, the output shaft of the servo motor 7 and the oil pollution monitor 3 can also drive the rotation center of the oil pollution monitor 3 through gear meshing.

[0051] Among them: when the servo motor 7 drives the oil pollution monitor 3 to perform pendulum motion, the detection end of the oil pollution monitor 3 is opposite to the transparent structure 9, and the swing trajectory of the straight line where the axis of the oil pollution monitor 3 is located at the bottom of the sealed shell 2 is always within the range of the transparent structure 9, and the servo motor 7 can control the oil pollution monitor 3 to hover at any point of the pendulum motion, and the hovering time is adapted to or exceeds the time length of the oil pollution monitor 3 emitting and receiving light once.

[0052] By making the light emitted by the oil pollution monitor 3 always flow within the transparent structure 9, the light is prevented from being irradiated on non-transparent structures (such as the sealed housing 2 and other structures that can directly reflect) to reflect erroneous light and cause data anomalies.

[0053] In some embodiments, a video surveillance camera can be used in conjunction with the sealed shell 2 (refer to the invention patent with application number 2021101494649) to detect the passage of ships through the video surveillance camera to avoid misjudgment. When the oil pollution monitor 3 performs detection in the swinging trajectory, it can randomly select points for hovering detection, or it can divide the trajectory into multiple detection points and then hover at the detection points. The present invention does not limit the method of selecting the points.

[0054] The above configuration can be referred to FIG2 , which is an embodiment of the scanning oil spill monitoring device of the present invention.

[0055] It can be seen that the present invention can make the oil pollution monitor 3 have a strong ability to resist wind and waves through the installation method. Moreover, the swing design of the oil pollution monitor 3 (i.e., scanning motion) can make the oil pollution monitor 3 have a larger detection range.

[0056] The present invention also discloses a non-scanning oil spill monitoring device, in an attempt to prove that the scanning oil spill monitoring device has a larger scanning range by comparing it with the non-scanning oil spill monitoring device:

[0057] 1 , the non-scanning oil spill monitoring device generally consists of a column 1, a sealed shell 2 fixed (generally by bolts) on a bracket, and an oil pollution monitor 3. The lower end of the oil pollution monitor 3 is a detection port. The oil pollution monitor 3 is arranged in the sealed shell 2 through a driving mechanism 4. The driving mechanism 4 of the non-scanning oil spill monitoring device is a linear motor or a telescopic cylinder that moves back and forth laterally. Accordingly, the range that the non-scanning oil spill monitoring device can detect is shown as a in FIG1 , where half of a is the width of the transparent structure 9.

[0058] 2 , the main difference between the present scanning oil spill monitoring device and the aforementioned non-scanning oil spill monitoring device is that its driving mechanism 4 is composed of a rotating setting mechanism of the oil pollution monitor 3 and a servo motor 7, so that the servo motor 7 can drive the oil pollution monitor 3 to perform a pendulum motion. Its detection range is shown in b in FIG2 . Obviously, the present scanning oil spill monitoring device can obtain a better scanning range under the same spatial constraints.

[0059] In some embodiments of the present invention:

[0060] The oil pollution monitor 3 is rotatably mounted in the sealed housing 2 via a movable mounting component; the movable mounting component is used to convert the rotary motion of the output shaft of the servo motor 7 into a reciprocating swing within a preset angle.

[0061] Specifically, the movable mounting component is a further optimization of the rotation setting of the oil pollution monitor 3. The movable mounting component converts the 360-degree rotation of the output shaft of the servo motor 7 into a positive and negative 30-degree back and forth swing of the oil pollution monitor 3 through a mechanical setting. The advantage of such a setting is that there is no need to repeatedly control the positive and negative rotation of the servo motor 7 and control the amplitude of its positive and negative rotation.

[0062] In some embodiments of the present invention:

[0063] 3 and 4 , the movable mounting components include: a circular plate 83 rotatably mounted in the sealed housing 2, and the circular plate 83 is transmission-connected to the servo motor 7 via a transmission shaft 80, and a protrusion 89 is provided on a side plane of the circular plate 83 close to the oil contamination monitor 3; a swing plate 82 rotatably mounted in the sealed housing 2, a strip-shaped slide groove 84 being provided on the upper portion of the swing plate 82, and a tooth portion 87 being provided on the lower end of the swing plate 82, and the oil contamination monitor 3 is mounted on the upper portion of the swing plate 82 via a connector 81; The slide rod 85 is fixed in the sealed shell 2; the balance block 86 is slidably provided on the slide rod 85 through a slide hole, and the upper end of the balance block 86 is provided with a tooth portion 2 engaged with the tooth portion 1 87; the protrusion 89 is embedded in the strip slide groove 84, and the servo motor 7 drives the protrusion 89 of the circular plate 83 to perform circular motion. The protrusion 89 is used to convert the lateral displacement and vertical displacement of its own circular motion process into the lateral swing of the swing plate 82 and the longitudinal relative sliding between the swing plate and the strip slide groove 84.

[0064] Specifically, the conversion process of the movable mounting component is as follows: first, the servo motor 7 outputs rotation to the center of the circular plate 83, causing the circular plate 83 to rotate around its own center line, thereby driving the protrusion 89 on the circular plate 83 to rotate. Since the protrusion 89 is set on a certain diameter of the circular plate 83, the rotation trajectory of the protrusion 89 is annular, and the protrusion 89 is restricted to be nested in the bar slide 84 for linear sliding. Therefore, the lateral movement after the annular motion of the protrusion 89 is decomposed is directly transmitted to the swing plate 82 through the bar slide 84, and the longitudinal movement after the annular motion of the protrusion 89 is decomposed is converted into relative sliding between the protrusion 89 and the bar slide 84, so its longitudinal movement cannot be transmitted to the swing plate 82, and the middle part of the swing plate 82 is rotatably mounted by the rotating mounting shaft 88, so the lateral swinging force is applied to the upper end of the swing plate 82, causing the swing plate 82 to swing back and forth around the rotating mounting shaft 88.

[0065] At the same time, the lower end of the swing plate 82 drives the balance block 86 to slide back and forth on the slide bar 85 through the engagement of the tooth portion 1 87 and the tooth portion 2, so that the swing plate 82 swings in opposite directions to balance the inertia at both ends of the swing plate 82.

[0066] In some embodiments of the present invention, since the oil pollution monitor 3 is fixed to the upper end of the swing plate 82, a counterweight block is provided on the balance block 86, and the weight of the counterweight block is adapted to the weight of the oil pollution monitor 3 to further balance the inertia of the movement of the oil pollution monitor 3.

[0067] In some embodiments of the present invention:

[0068] An isolation cavity 5 is fixed on the side of the sealed shell 2 away from the center of the water surface; the servo motor 7 is arranged in the isolation cavity 5, and a channel connecting the sealed shell 2 and the cavity 3 is provided between the two. The outer end of the output shaft of the servo motor 7 passes through the channel and is connected to the transmission shaft 80 through a coupling.

[0069] The output shaft of the servo motor 7 is rotatably mounted in the channel via a bearing, which can provide stable support for the output shaft of the servo motor 7 .

[0070] In some embodiments of the present invention:

[0071] As shown in Figures 5 to 7, the snap-fit ​​assembly includes a mounting groove 151 provided on the sealed housing 2. The mounting groove 151 is provided with a first step 1511 and a second step 1512 from the inside to the outside. The transparent structure 9 is embedded in the first step 1511. A pressure plate 152 is embedded in the second step 1512. A plurality of pneumatic clamps 153 (four in this embodiment) are also provided around the periphery of the second step 1512. The plurality of pneumatic clamps 153 cooperate with each other to press the pressure plate 152 onto the transparent structure 9. An engaging structure is also provided between the pressure plate 152 and the surface of the second step 1512. The engaging structure includes a sealing rubber ring 154 embedded in the second step 1512, and a rubber column 156 is provided on the pressure plate 152 for embedding in the sealing rubber ring 154. The interior of the rubber column 156 is hollow and contains a piston 157. An airbag 158 is located at the lower end of the piston 157. A passage connects the inner cavity of the rubber column 156 with the airbag 158. All pistons 157 are connected together by an integral plate 1571. The secondary step 1512 is connected to the integral plate 1571 via a telescopic rod 159. The inner cavity of the sealing rubber ring 154 communicates with the inner cavity of the sealing housing 2 via a connecting pipe 150, which is equipped with an automatic valve 1501.

[0072] When the rubber column 156 on the pressure plate 152 is embedded in the rubber ring, the piston 157 is pulled outward by the telescopic rod 159, and all the pistons 157 are connected into one by the integrated plate 1571 for simultaneous control; if the rubber column 156 and the rubber ring are sealed, the automatic valve 1501 in the connecting pipe 150 is in a closed state at this time, thereby pulling the piston 157 outward to make the rubber column 156 in a negative pressure state, and the airbag 158 is in a contracted state; if the rubber column 156 and the rubber ring are not sealed, pulling the piston 157 outward will not change the air pressure in the rubber column 156, and ultimately achieve the function of verifying the sealing effect.

[0073] After verifying the sealing, the automatic valve 1501 in the connecting pipe 150 is opened, and the airbag 158 is connected to the sealed shell 2. Since the sealed shell 2 is erected at a high altitude, and since the scanning oil spill monitoring equipment is a scanning detection, it has a large space inside. The scanning oil spill monitoring equipment is set at the seaside and is directly exposed to sunlight during the day, which will cause the air pressure in the sealed shell to increase. There is a risk of deformation and cracking of the sealed shell, and it is easy to cause pressure on some sealing structures of the oil pollution monitor 3. In winter or at night, the temperature drops, which will cause the air pressure inside the sealed shell to drop. The low air pressure will affect the electrical components. In addition, high-pressure and under-pressure states may alternate in the sealed shell, which will cause the transparent structure and the lens (generally brittle glass material) to be easily broken. In the present invention, the air pressure changes in the inner cavity of the sealed shell 2 can be balanced by the expansion and contraction of the airbag 158 to avoid the occurrence of the above problems.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
