Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and in particular to a marine sampling container placement device. Background Technology

[0002] There are increasingly more sampling points on ships requiring external containers, such as stern pipe lubricating oil sampling, ballast water sampling, and fuel oil sampling, especially fuel oil sampling points, which are numerous. Currently, ship designs rarely consider the placement of sampling containers. After delivery, crew members basically have to rely on manually holding the sampling containers to collect samples. If sampling is conducted while the ship is underway, a sudden rocking motion may prevent crew members from keeping the sampling container aligned with the sampling tube, causing the sampled liquid to leak outside the container. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a marine sampling container placement device that can fix the sampling container in place and prevent the sampling liquid from splashing around during sampling.

[0004] To address the aforementioned technical problems, this invention provides a marine sampling container placement device, comprising a support frame and an oil pan. The support frame includes a fixed plate, a movable plate, a supporting plate, and a limiting rod. Both the fixed plate and the movable plate are U-shaped plates. The fixed plate is vertically positioned, and the movable plate is horizontally positioned. One end of the movable plate is rotatably connected to the top of the fixed plate. The side of the movable plate has a guide groove extending along its length. One end of the supporting plate is hinged to the side of the fixed plate, and the other end of the supporting plate has a connecting shaft slidably connected to the guide groove. The top end of the limiting rod abuts against the connecting shaft, and the limiting rod is connected to a rotating shaft. The rotating shaft is rotatably connected to the side of the movable plate, and one end of the rotating shaft is connected to a torsion spring. The other end of the torsion spring is connected to the movable plate. The oil pan includes a base plate and a cylinder. The base plate is fixed to the top of the movable plate, and the cylinder is fixed to the base plate. The side of the cylinder is provided with a plurality of fixing screws evenly distributed around the axis of the cylinder. One end of the fixing screw passes through the side wall of the cylinder. The fixing screw is provided with a first nut and a second nut. The first nut and the second nut cooperate to clamp the side wall of the cylinder. The other end of the fixing screw is provided with a fixing block. The inner sides of the plurality of fixing blocks are combined to form a placement area for placing a sampling container.

[0005] As a preferred embodiment of the present invention, it further includes a mounting block and a retractable corrugated pipe. The top of the fixing block is provided with an adjustment groove arranged along the length direction of the fixing screw connected thereto. The mounting block is disposed on the fixing block. The bottom of the mounting block is provided with a connecting post that is slidably connected to the adjustment groove. The bottom end of the corrugated pipe is fixed on the mounting block. The projection area of ​​the placement area on the base plate is located within the projection area of ​​the inner hole of the corrugated pipe on the base plate.

[0006] As a preferred embodiment of the present invention, a connecting rod is connected to the top side of the corrugated pipe, and a connecting rope for fixing to the sampling tube is connected to the top of the connecting rod.

[0007] As a preferred embodiment of the present invention, a shock-absorbing pad is provided on the inner side of the fixing block, and a buffer spring is provided between the inner side of the fixing block and the shock-absorbing pad.

[0008] As a preferred embodiment of the present invention, a locking stud is hinged to the bottom end of the fixing plate, a locking nut is provided on the locking stud, and a locking block is provided on the side of the locking nut.

[0009] This invention discloses a marine sampling container placement device. Compared with the prior art, its advantages are as follows: the device can be folded or unfolded. When the device is folded, the movable plate is placed on the fixed plate, effectively reducing the overall volume and facilitating storage. When the device is unfolded, the movable plate is horizontally positioned for sampling operations. After the sampling container is placed in the placement area, the position of the fixing screw can be adjusted by adjusting the first nut and the second nut, thereby adjusting the position of the limiting block. This allows for clamping and fixing of sampling containers of different specifications, making it highly adaptable. There is no need to hold the sampling container by hand. If the ship suddenly rocks, the sampling container will not tip over, and the oil pan can collect liquid that did not flow into the sampling container due to shaking or liquid that overflowed from the sampling container, preventing liquid from spreading to the surroundings.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on this invention. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figure 1-5 As shown, a preferred embodiment of the present invention provides a marine sampling container placement device, comprising a support frame 1 and an oil pan 2. The support frame 1 includes a fixed plate 11, a movable plate 12, a support plate 13, and a limiting rod 14. Both the fixed plate 11 and the movable plate 12 are U-shaped plates. Figure 1As shown, the device is in the unfolded state. At this time, the fixed plate 11 is vertically positioned, and the movable plate 12 is horizontally positioned. One end of the movable plate 12 is rotatably connected to the top of the fixed plate 11. Specifically, one end of the movable plate 12 extends into the interior of the fixed plate 11, and the ends of the movable plate 12 are rotatably connected to the top two sides of the movable plate 12. The side of the movable plate 12 is provided with a guide groove 121 arranged along the length of the movable plate 12. One end of the support plate 13 is hinged to the side of the fixed plate 11, and the other end of the support plate 13 is provided with a connecting shaft 1 that is slidably connected to the guide groove 121. 31. The top end of the limiting rod 14 abuts against the connecting shaft 131. The limiting rod 14 is rotatably connected to the side of the movable plate 12 via the rotating shaft 141. The rotating shaft 141 is connected to one end of the torsion spring 142, and the other end of the torsion spring 142 is connected to the movable plate 12. When the limiting rod 14 rotates towards the fixed plate 11, the torsion spring 142 twists and generates elastic force. Specifically, when the device is in the unfolded state, the connecting shaft 131 is located at the end of the guide groove 121 near the fixed plate 11. It should be noted that at this time, the guide groove 121 still has a connection point. The space for the shaft 131 to slide towards the fixed plate 11 is such that, under its own weight, the movable plate 12 causes the connecting shaft 131 to tend to slide away from the fixed plate 11. At this time, the limiting rod 14 is located on the side of the connecting shaft 131 away from the fixed plate 11 and abuts against the connecting shaft 131, preventing the movable plate 12 from rotating downwards and thus maintaining a horizontal setting. The oil pan 2 includes a base plate 21 and a cylinder 22. The base plate 21 is fixed to the top of the movable plate 12, and the cylinder 22 is fixed to the base plate 21. The side of the cylinder 22 is provided with multiple shafts surrounding the cylinder 22. The fixing screws 23 are evenly distributed. One end of the fixing screws 23 passes through the side wall of the cylinder 22. The fixing screws 23 are provided with a first nut 231 and a second nut 232. The first nut 231 and the second nut 232 cooperate to clamp the side wall of the cylinder 22. After the first nut 231 and the second nut 232 are loosened, the fixing screws 23 can move along their length to adjust their position. The other end of the fixing screws 23 is provided with a fixing block 24. The inner sides of multiple fixing blocks 24 (i.e. the side near the center of the cylinder 22) are combined to form a placement area 25 for placing a sampling container.

[0022] The specific process of switching the device from the unfolded state to the folded state is as follows: First, rotate the fixed plate 11 upward (the guide groove 121 provides space for the connecting shaft 131 to slide towards the fixed plate 11). Then, rotate the limiting rod 14 below the connecting shaft 131. At this time, the limiting rod 14 no longer restricts the sliding of the connecting shaft 131, that is, the movable plate 12 is unrestricted. Under its own gravity, the movable plate 12 rotates downward into the fixed plate 11, thereby switching the device from the unfolded state to the folded state. Afterward, when it is necessary to switch the device to the unfolded state, simply rotate the movable plate 12 upward until the connecting shaft 131 slides to the side of the limiting rod 14 near the fixed plate 11 and abuts against it.

[0023] The working principle of this embodiment is as follows: The support frame 1 is fixed to the hull structure or iron outfitting. For easy storage, the device is usually in a folded state. The device is then switched from the folded state to the unfolded state. The sampling container is placed in the placement area 25 and below the sampling tube 6. Next, by adjusting the first nut 231 and the second nut 232, the position of the fixing screw 23 is adjusted, causing the limiting blocks to move inwards until the multiple limiting blocks abut against the sides of the sampling container, locking the first nut 231 and the second nut 232. At this point, the multiple limiting blocks cooperate to clamp and fix the sampling container, thus securing it for sampling operations without the need for handheld handling. The sampling container will not tip over if the ship suddenly rocks. The oil pan 2 can collect liquid that did not flow into the sampling container due to shaking or liquid that overflowed from the sampling container, preventing the liquid from spreading to the surroundings. After sampling is completed, adjust the position of the fixing bolts to loosen the limiting block of the sampling container, and finally take the sample out from the placement area 25. It is understood that if the space under the sampling tube 6 is insufficient to put the sampling cup 5 into the placement area 25 when the device is unfolded, the sampling cup 5 can be put into the placement area 25 and fixed during the process of switching the device from the folded state to the unfolded state, for example, when the movable plate 12 is rotated to an angle of 45° with the vertical direction.

[0024] This device can be folded or unfolded. When the device is folded, the movable plate 12 is placed on the fixed plate 11, which effectively reduces the overall volume and facilitates storage. When the device is unfolded, the movable plate 12 is set horizontally for sampling operations. After the sampling container is placed in the placement area 25, the position of the fixing screw 23 can be adjusted by adjusting the first nut 231 and the second nut 232, thereby adjusting the position of the limiting block. It can clamp and fix sampling containers of different specifications, which is highly applicable. There is no need to hold and fix the sampling container by hand. If the ship suddenly rocks, the sampling container will not tip over. The oil pan 2 can collect the liquid that did not flow into the sampling container due to shaking or the liquid that overflowed from the sampling container, preventing the liquid from spreading to the surroundings.

[0025] For example, it also includes a mounting block 3 and a retractable bellows 4. The top of the fixing block 24 is provided with an adjusting groove 241 arranged along the length direction of the fixing screw 23 connected thereto. The mounting block 3 is disposed on the fixing block 24, and the bottom of the mounting block 3 is provided with a connecting post 31 that is slidably connected to the adjusting groove 241. The bottom end of the bellows 4 is fixed on the mounting block 3. The projection area of ​​the placement area 25 on the base plate 21 is located within the projection area of ​​the inner hole of the bellows 4 on the base plate 21. When the sampling container is fixed in the placement area 25, the sampling container position... Inside the bellows 4, the bellows 4 is stretched upwards until the top of the bellows 4 is higher than the liquid outlet of the sampling tube 6. At this time, the bellows 4 surrounds the liquid outlet of the sampling tube 6. When the sampling liquid splashes due to the large swaying of the ship, the bellows 4 can prevent it from splashing outside the oil pan 2. When adjusting the position of the fixing block 24, the connecting column 31 slides relative to the fixing block 24 along the adjusting groove 241. That is, the mounting block 3 and the bellows 4 remain stationary, which will not affect the adjustment of the position of the fixing block 24. At the same time, it can also ensure that the bellows 4 is in a position that can work normally.

[0026] For example, a connecting rod 41 is connected to the top side of the corrugated pipe 4, and a connecting rope (not shown in the figure) for fixing to the sampling tube 6 is connected to the top of the connecting rod 41. When the corrugated pipe 4 extends upward, the connecting rope is tied to the sampling tube 6, so that the connecting rod 41, the corrugated pipe 4 and the sampling tube 6 are relatively fixed to keep the corrugated pipe 4 in an extended state; in addition, in other embodiments, such as Figure 6-8 As shown, the bellows 4 has connecting rods 41 on both sides of its top end. A connecting block 42 is rotatably connected to the top of each connecting rod 41. A movable connecting rod 43 passes through the connecting block 42. A pushing block 44 is provided at one end of each connecting rod 41. The two pushing blocks 44 can be connected by bolts. Before the sampling cup 5 is placed in the placement area 25, the connecting block 42 is rotated so that the pushing block 44 is positioned away from the axis of the cylinder 22. Figure 6 As shown, to prevent the push block 44 from obstructing the insertion of the sampling cup 5, after the sampling cup 5 is fixed in the placement area 25 and the corrugated tube 4 is extended, rotate the connecting block 42 so that the push block 44 is located on the side of the connecting block 42 close to the sampling tube 6. Then slide the push block 44 so that the two push blocks 44 abut against the sampling tube 6 respectively. Finally, use bolts to fix the two push blocks 44 together, so that the corrugated tube 4 and the sampling tube 6 can be fixed.

[0027] For example, a shock-absorbing pad 27 is provided on the inner side of the fixing block 24, and a buffer spring 26 is provided between the inner side of the fixing block 24 and the shock-absorbing pad 27. That is, one end of the buffer spring 26 is connected to the inner side of the fixing block 24, and the other end of the buffer spring 26 is connected to the shock-absorbing pad 27. The buffer spring 26 can buffer vibration, while the shock-absorbing pad 27 can dampen shock. When the sampling container is fixed in the placement area 25, the impact of the hull swaying on the sampling cup 5 can be reduced.

[0028] For example, a locking stud 111 is hinged to the bottom end of the fixed plate 11, and a locking nut 112 is provided on the locking stud 111. A locking block 113 is provided on the side of the locking nut 112. When the device is in the folded state, the locking stud 111 can be rotated to a horizontal position, and then the locking nut 112 can be tightened, so that the locking block 113 presses against the bottom plate 21 or the movable plate 12, so that the movable plate 12 is in a locked state and cannot rotate freely, thereby preventing it from shaking due to the movement of the ship.

[0029] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
