Description

Technical Field

[0001] The invention relates to the technical field of marine environmental protection equipment, in particular to a test device for removing oil pollution from a sea surface, a usage method and a driving mechanism thereof. Background Art

[0002] Marine oil pollution has become the main type of marine pollution, causing great damage to the marine aquatic environment, and oil spills have become the main way for oil to enter the ocean. How to effectively prevent and deal with oil spills has become the key to controlling marine pollution.

[0003] At present, the commonly used methods for controlling marine oil pollution include physical remediation, chemical remediation and biological remediation. Compared with chemical and physical methods, biological treatment has less impact on humans and the environment, and the cost of remediation is only 30%-50% of traditional physical and chemical remediation. Biological remediation is regarded as the most promising and cost-effective environmental governance method due to its low investment and no secondary pollution.

[0004] The biological method is to artificially select, cultivate, and even improve these oil-eating microorganisms, and then release them into polluted sea areas to carry out artificial biodegradation of petroleum hydrocarbons.

[0005] In order to increase the degradation rate of bioremediation, the following methods are usually used:

[0006] 1. Add biosurfactants to increase the contact area between oil and microorganisms in water;

[0007] 2. Add microorganisms that can efficiently degrade petroleum to increase the population of microorganisms;

[0008] 3. Add nutrients such as N and P to promote the degradation of petroleum by indigenous microorganisms;

[0009] However, the specific amount of addition requires the tester to conduct experiments step by step. The existing test method is to simulate a certain amount of oil-contaminated seawater in a conical flask, put different types of test agents into each of them, place the conical flask on a shaker and shake it for a certain period of time, and then test the remaining total petroleum hydrocarbon concentration in the conical flask to obtain the most appropriate amount of addition through multiple tests.

[0010] In actual experiments, a lot of manpower and material resources are required, and the shaker cannot intuitively simulate the dynamics of seawater (the degradation rate of microorganisms is related to the movement, distribution, morphology and dissolved oxygen content of the oil in the system), resulting in inaccurate measurements and the experiment is not intuitive enough.

The utility model is provided with a positioning screw and an adapter seat in the traditional shaker for bacterial strain culture. When there are fewer flasks, only the positioning screw is used to plug the adapter seat that can be used, and the nut is tightened to rotate and shake the placement plate of a specified layer, thereby reducing the input of rotational power and reducing energy consumption.

[0012] This prior art cannot simulate the seawater environment and cannot be used for testing the effect of oil pollution removal.

Such a structure can clamp test tubes or flasks, and even if the depths of the culture dishes are different, it does not affect the clamping of the device, and the top of the device covers the opening of the culture dish through the smooth plate, and the smooth plate can fit inside the box cover and shake freely to cover the culture dish.

[0014] This prior art cannot simulate the seawater environment and cannot be used for testing the effect of oil pollution removal.

DETAILED DESCRIPTION

[0082] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0083] Embodiment 1:

[0084] See also Figure 1 to Figure 2 The present invention provides a test device for removing oil pollution from a sea surface, a method for using the device and a driving mechanism, comprising a housing 1, a bearing plate and a driving mechanism 3;

[0085] The shell 1 includes a lower shell 1-1 and a protective cover. An opening is set at the top of the lower shell 1-1. The protective cover is rotatably set at the opening of the lower shell 1-1. The protective cover is made of transparent material and can prevent the operator from accidentally contacting the shell 1. A handle is set in the middle of the protective cover for the operator to open it. The front and rear ends of the inner wall of the protective cover are both provided with support rods connected to the lower shell, and the protective cover is supported by the support rods after opening; two slide rails 1-2 are set in parallel at the opening of the lower shell 1, and two sliders 1-3 are slidably connected to each slide rail 1-2. A bearing plate 1-4 is fixedly set on the upper end surfaces of all sliders 1-3, and two receiving grooves are set on the plate body of the bearing plate 1-4. The receiving grooves are used to place conical flasks containing seawater.

[0086] The driving mechanism 3 is arranged in the lower shell 1-1 and connected to the bearing plate 1-4, and is used to drive the bearing plate 1-4 to move back and forth; the slider 1-3 and the slide rail 1-2 can reduce the resistance of the bearing plate 1-4 during reciprocating movement, thereby reducing the workload of the driving mechanism 3.

[0087] The driving mechanism 3 includes a rotating shaft 3-1 rotatably arranged in the lower shell body 1-1, and an active dial 3-2, a driven dial 3-3, and an input wheel 3-5 are arranged on the rotating shaft 3-1; the active dial 3-2 is connected to the rotating shaft 3-1 by a key, and can slide axially and rotate synchronously; a swing hole is arranged at the center of the driven dial 3-3, and an active hole perpendicular to the swing hole is arranged on the outer wall of the driven dial 3-3, the rotating shaft 3-1 is movably connected to the driven dial 3-3 through the active hole, and the driven dial 3-3 can rotate around the active hole and rotate synchronously with the rotating shaft 3-1; the input wheel 3-5 is fixedly connected to the rotating shaft 3-1 and can rotate synchronously; the active dial 3-2 is connected to the fixing mechanism, and a connecting rod 3-4 is arranged between the driven dial 3-3 and the active dial 3-2; the driven dial 3-3 is connected to the bearing plate 1-4, and the input wheel 3-5 is connected to the power mechanism.

[0088] The fixing mechanism includes a shift fork 3-9 and an adjusting screw 3-10; an annular groove 3-21 is provided on the outer surface of the active dial 3-2; the shift fork 3-9 includes two fork legs and a fork body; the two fork legs are arranged in the annular groove 3-21; the fork body is threadedly connected to the adjusting screw 3-10; the adjusting screw 3-10 passes through the lower shell 1-1 to the outside; a knob 3-11 is provided on the outer part of the adjusting screw 3-10; the moving direction of the shift fork 3-9 is controlled by the adjusting screw 3-10.

[0089] A roller is rotatably provided at the end of each of the two fork legs, and the roller rolls in the annular groove 3-21. The roller can reduce the friction coefficient between the fork 3-9 and the active dial 3-2, and change the sliding friction into rolling friction, thereby increasing the service life of the fork 3-9 and the active dial 3-2. At the same time, the gap between the fork 3-9 and the active dial 3-2 can be reduced, thereby increasing the accuracy of adjusting the active dial 3-2.

[0090] A guide ring groove 3-31 is provided on the outer wall of the driven dial 3-3, a guide rod 1-41 is fixedly arranged on the lower surface of the supporting plate 1-4, a guide ball 1-42 is arranged at the lower end of the guide rod 1-41, and the guide ball 1-42 extends into the guide ring groove 3-31 and slides in the guide ring groove 3-31; the connecting rod 3-4 is movably connected with the driven dial 3-3 or the active dial 3-2.

[0091] The power mechanism includes a driving motor 3-8, and the driving motor 3-8 is fixedly arranged in the lower shell 1-1. An output wheel 3-6 is fixedly arranged on the motor shaft of the driving motor 3-8. The output wheel 3-6 and the input wheel 3-5 are both pulleys connected by belts; or the output wheel 3-6 and the input wheel 3-5 are both sprockets connected by a chain 3-7.

[0092] The diameter of the output wheel 3-6 is smaller than that of the input wheel 3-5. The small wheel drives the large wheel, reducing speed and increasing torque, which can reduce the load of the drive motor 3-8. The rotation of the drive shaft 3-1 can be achieved through a smaller-sized drive motor 3-8, which can reduce costs and the overall weight of the device, reducing the noise and vibration of the drive motor 3-8 during use.

[0093] Specifically, the rotating shaft is connected to the lower shell 1-1 through a seat bearing.

[0094] Specifically, the driving motor 3-8 is preferably a servo motor, which can control the speed. A speed regulating switch is provided on the lower housing 1-1, and the speed of the servo motor is controlled by the speed regulating switch. A display screen for displaying the rotation speed of the rotating shaft 3-1 is also provided on the lower housing 1-1, so that the operator can intuitively record the data during the test, thereby improving the intuitiveness of the test. The display screen is also used to display the reciprocating distance of the bearing plate 1-4, so that the operator can intuitively record the data during the test, thereby improving the intuitiveness of the test. The control method of the servo motor and the speed data output display are both prior arts, and those skilled in the art are clear about this.

[0095] Specifically, the driven dial 3-3 and the guide ball 1-42 are both made of wear-resistant nylon. Wear-resistant nylon has a lower friction coefficient, a higher PV value, better friction and wear resistance, better self-lubrication, and good wear resistance, heat resistance, oil resistance and chemical resistance. It also greatly reduces the water absorption and shrinkage of the raw materials. It has excellent dimensional stability and mechanical strength, and is widely used in friction and wear structural parts.

[0096] When the present invention is used, a certain volume of seawater is placed in the conical flask 4, a suitable initial concentration of petroleum is selected according to the test requirements, and the conical flask 4 is placed on the supporting plate 1-4, two groups of microorganisms of different quantities are added to different conical flasks 4 respectively, and the driving motor 3-8 is started. The driving motor 3-8 drives the supporting plate 1-4 to move back and forth continuously, so that the seawater in the conical flask 4 is shaken, simulating the dynamics of the seawater in the conical flask, and improving the authenticity of the test.

[0097] By selecting the appropriate shaking time according to the test and then measuring the hydrocarbon concentration of the remaining petroleum in the seawater, the effectiveness of different formulations of bacteria in treating petroleum-contaminated seawater can be determined.

[0098] The process and adjustment method of reciprocating movement: the driving motor 3-8 drives the input wheel 3-5 to rotate through the output wheel 3-6, thereby driving the rotating shaft 3-1 to rotate. When the rotating shaft 3-1 rotates, it drives the active dial 3-2 and the driven dial 3-3 to rotate respectively. When the reciprocating distance of the carrying plate 1-4 needs to be adjusted, the operator drives the fork 3-9 to move axially by rotating the adjusting screw 3-10. At this time, the fork 3-9 drives the active dial 3-2 to move. When the active dial 3-2 moves, the driven dial 3-3 is controlled to tilt a certain angle through the connecting rod 3-4. When the driven dial 3-3 rotates, the reciprocating movement of the carrying plate 1-4 is realized through the guide ball 1-42 in the guide ring groove 3-31. The continuous rotation of the rotating shaft 3-1 causes the carrying plate 1-4 to reciprocate uninterruptedly, so that the seawater in the conical flask 4 is shaken, simulating the dynamics of the seawater in the conical flask and improving the authenticity of the experiment.

[0099] Example 2

[0100] Based on Example 1, Figure 3 , Figure 4 Two clamping mechanisms 2 for clamping a conical flask 4 containing seawater are arranged on the plate body of the carrying plate 1-4;

[0101] The clamping mechanism 2 includes a bottom shell 2-1, a bottom plate 2-2, and a support plate 2-5; the accommodating groove is the bottom shell 2-1, the bottom plate 2-2 is slidably arranged in the bottom shell 2-1, at least three "C"-shaped clamp arms 2-3 are arranged in a circumferential array on the plate body of the bottom plate 2-2, and the support plate 2-5 is arranged above the bottom plate 2-2, and the bottom plate 2-2 and the support plate 2-5 are connected by a support plate spring 2-51, and the two ends of the support plate spring 2-51 are fixedly connected to the bottom plate 2-2 and the support plate 2-5 respectively; the support plate 2-5 is connected to each clamp arm 2-3 through a control arm 2-4, and the control arm 2-4 is movably connected to the support plate 2-5 or the clamp arm 2-3, and a top plate 2-6 is fixedly arranged on the upper surface of the support plate 2-5, and a conical flask 4 is placed on the top plate 2-6;

[0102] A rubber ball is fixedly arranged at the top of each clamp arm 2 - 3 , and the rubber ball can make the contact between the clamp arm 2 - 3 and the conical flask 4 become a flexible contact, thereby preventing the clamp arm 2 - 3 from damaging the conical flask 4 .

[0103] When the conical flask 4 is placed on the top plate 2-6, the top plate 2-6 is subjected to the gravity of the conical flask 4 to press down the support plate 2-5. When the support plate 2-5 moves, it drives the clamping arm 2-3 to move through the control arm 2-4. The movable end of the clamping arm 2-3 moves toward the upper part of the conical flask 4, and the conical flask 4 is fixed by the clamping arm 2-3. The fixing method is simple and fast, and no additional tools are needed. Without applying external force, the clamping mechanism 2 can always clamp the conical flask 4.

[0106] Two "L"-shaped fixtures 2-52 are fixedly arranged on the lower surface of the support plate 2-5, and the horizontal parts of the fixtures 2-52 are arranged face to face; when the support plate 2-5 moves downward, the limit hooks 2-7 overlap with the fixtures 2-52 respectively. At this time, a stable whole is formed between the support plate 2-5 and the bottom plate 2-2, and the conical flask 4 can be firmly fixed in the multiple clamping arms 2-3, which can prevent the conical flask 4 from detaching from the clamping mechanism 2 when the clamping mechanism shakes.

[0107] An unlocking platform 2-11 is fixedly arranged in the middle of the bottom shell 2-1, and a "V"-shaped unlocking groove 2-12 is provided on the upper surface of the unlocking platform 2-11.

[0108] A return spring 2-9 is arranged between the bottom shell 2-1 and the bottom plate 2-2, and the two ends of the return spring 2-9 are fixedly connected to the bottom shell 2-1 and the bottom plate 2-2 respectively, and the elastic coefficient of the return spring 2-9 is greater than that of the support plate spring 2-51.

[0109] An arc portion is provided on the upper part of each limit hook 2-7, which facilitates the limit hook 2-7 to be inserted into the fixer 2-52, and an arc angle is provided on the lower part, which facilitates the limit hook 2-7 to move in the unlocking groove 2-12.

[0110] When the conical flask 4 is placed on the top plate 2-6, the gravity of the conical flask 4 will only compress the support plate spring 2-51, which is not enough to compress the return spring 2-9, so that the support plate 2-5 moves downward, so that the limit hook 2-7 overlaps with the fixer 2-52, which can limit the position of the support plate 2-5 without affecting the movement of the bottom plate 2-2;

[0111] When it is necessary to remove the conical flask 4, the operator presses the conical flask 4 downward to compress the reset spring 2-9. At this time, the bottom plate 2-2 drives the two limit hooks 2-7 to move during the downward movement. The lower ends of the limit hooks 2-7 move along the unlocking groove 2-12. Due to the sliding connection between the limit hooks 2-7 and the bottom plate 2-2, the limit hooks 2-7 move in directions close to each other. At this time, the limit hooks 2-7 are separated from the fixture 2-52. Then the operator moves the conical flask 4 upward. After losing the gravity of the conical flask 4, the top plate 2-6 moves upward under the action of the support spring 2-51. At this time, the three clamping arms 2-3 are in an open state, which is convenient for the operator to take out the conical flask 4.
