Description

Technical Field

[0001] The invention relates to an angle-adjustable component icing measurement and runoff water collection device, belonging to the technical field of ship and marine structure icing and anti-icing research. Background Art

[0002] Ships and marine structures are prone to icing when sailing or operating in low-temperature waters. The amount of ice can reach hundreds of tons. Ice accumulation will not only reduce the stability of the ship, but also freeze the deck equipment and affect normal operations. In serious cases, it will threaten the lives of people on board. The icing of the superstructure of ships and marine structures is mainly caused by the freezing of droplets. A large amount of wind-generated or wave-generated droplets move under the action of wind and their own gravity, and some droplets hit the surface of the structure and freeze. The components in the surface structure of the ship's superstructure are mainly plates. There are many angles of the plates. The plates at different angles have differences in the amount of droplets received, which leads to different final ice amounts. Therefore, it is necessary to develop a seawater droplet icing test device to explore the icing mechanism of the surface plates of the ship's superstructure, so as to master the freezing and runoff mechanism of the ship's droplets after hitting different types of structures, and provide data support and scientific guidance for improving the accuracy of ship icing forecast methods and developing more efficient anti-icing and de-icing technologies.

[0003] The icing components in the existing seawater spray freezing devices are mostly fixed vertical cylinders, which cannot simulate the freezing process on the surface of the inclined structures that are widely distributed in the ship superstructure. In addition, the droplet diameters and speeds in the seawater spray groups at different heights are different, which in turn affects the amount of freezing. The fixed icing components can only obtain the amount of freezing at a specific height, and their applications are limited. Therefore, there is an urgent need for an angle-adjustable component icing measurement and runoff water collection device, so that the icing components can be rotated at different angles and adjusted to different heights, and can cover most of the components on the surface of the ship superstructure.

[0004] There are also devices capable of automatically adjusting the angle in other existing technical fields, but such devices generally require drive structures and electrical circuits to control the rotation angle. When applied to icing tests, it is very easy for the rotation position, drive structure and / or electrical circuits to freeze and become inoperable. Therefore, the existing devices capable of automatically adjusting the angle are not suitable for seawater splash icing tests. Summary of the invention

The angle adjustment assembly includes a first limiting cylinder and a second limiting cylinder coaxially mounted from inside to outside. The first limiting cylinder is a cylindrical structure with a round outer surface and a square inner surface, the second limiting cylinder is a cylindrical structure, the cross beam of the lifting bracket is a rectangular tubular structure or a rectangular rod structure, the first limiting cylinder is sleeved on the cross beam, and a first weight sensor is arranged between the top inner wall of the first limiting cylinder and the top of the cross beam, The first limiting cylinder is provided with a plurality of limiting blind holes distributed along its circumference, and each limiting blind hole is opened along the radial direction of the first limiting cylinder.

Therefore, they cannot be understood as limitations on the present invention. In the description of the present invention, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0024] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] An angle-adjustable component icing measurement and runoff water collection device comprises a lifting bracket 1, a runoff water collection container 2 and an angle adjustment component 3, wherein the lifting bracket 1 is installed in the runoff water collection container 2, and a component to be measured 100 is installed on the top of the lifting bracket 1 through the angle adjustment component 3 and the position adjustment in the height direction is realized through the lifting bracket 1. The angle adjustment assembly 3 includes a first limiting cylinder 31 and a second limiting cylinder 32 coaxially mounted from inside to outside. The first limiting cylinder 31 is a cylindrical structure with a round outer surface and a square inner surface, the second limiting cylinder 32 is a cylindrical structure, the cross beam 11 of the lifting bracket 1 is a rectangular tubular structure or a rectangular rod structure, the first limiting cylinder 31 is sleeved on the cross beam 11, and a first weight sensor 4 is arranged between the top inner wall of the first limiting cylinder 31 and the top of the cross beam 11. The first limiting cylinder 31 is provided with a plurality of limiting blind holes 31-1 distributed along its circumference, and each limiting blind hole 31-1 is opened along the radial direction of the first limiting cylinder 31. The second limiting cylinder 32 is provided with a plurality of limiting through holes 32-1 distributed along its circumference, and the plurality of limiting blind holes 31-1 and the plurality of limiting through holes 32-1 are arranged one by one in the radial direction of the second limiting cylinder 32. The circumferential limiting between the two limiting cylinders is achieved by inserting limiting members 9 into the corresponding limiting through holes 32-1 and limiting blind holes 31-1. The component to be tested 100 is fixed on the second limiting cylinder 32 .

[0026] The component to be tested 100 is installed at a certain angle on the lifting bracket 1 through the angle adjustment component 3. The bottom end of the component to be tested 100 is arranged higher than the runoff water collection container 2 to prevent the side wall of the runoff water collection container 2 from affecting the splashes from hitting the component to be tested 100, thereby improving the accuracy of the icing test structure.

[0027] During the test, some of the droplets will form a water film after hitting the surface of the component to be tested 100. Part of the water in the water film flows downward under the action of gravity and leaves the surface of the component to be tested 100 to form runoff water. A runoff water collection container 2 is provided to collect the runoff water.

[0028] The outer wall of the first limiting cylinder 31 and the inner wall of the second limiting cylinder 32 are both circular and matched with each other. By matching the inner hole of the first limiting cylinder 31 with a rectangular cross section and the cross beam 11 with a rectangular cross section, the circumferential limiting of the first limiting cylinder 31 on the cross beam 11 can be achieved by utilizing the structural advantages of the rectangular structure, eliminating other circumferential limiting structures, and further simplifying the structural composition of the angle adjustment component 3.

[0029] The plurality of limiting through holes 32 - 1 and the plurality of limiting blind holes 31 - 1 are evenly distributed along the circumferential direction.

[0030] In the present invention, an angle adjustment component 3 is provided to lift the bracket 1, so as to realize the angle change and height change of the component to be tested 100, obtain the icing conditions at different windward positions in the ship superstructure, solve the problem that the traditional icing device can only simulate the flow in a single direction (horizontal direction), avoid replacing the component to be tested 100 multiple times, and effectively improve the test efficiency.

[0031] The angle-adjustable component icing measurement and runoff water collection device of the present invention can be applied to typical ship structure icing tests, and can collect icing information (such as ice thickness, etc.) of the component to be tested 100 under specific icing conditions, wherein the component to be tested 100 can be other typical components of ship superstructures such as cylinders or plates.

[0032] The angle-adjustable component ice measurement and runoff water collection device of the present invention has an angle adjustment component 3 that is manually adjusted, which is simple and convenient to operate. In a low-temperature environment, the various components in the angle adjustment component 3 are not easily damaged, making it more suitable for seawater splash ice testing.

[0033] The first weight sensor 4 is arranged between the first limiting cylinder 31 and the crossbeam 11 to measure the change of the amount of ice on the surface of the component to be tested 100 during the icing test.

[0034] The runoff water collection container 2 is a cylindrical structure.

[0035] The runoff water collection container 2 is supported by a support frame 5 arranged at the bottom thereof. The support frame 5 is provided to prevent the runoff water collection container 2 from freezing due to contact with the ground. The support frame 5 is preferably fixedly connected to the bottom end of the runoff water collection container 2. The support frame 5 may be three rod-like structures uniformly distributed circumferentially at the bottom end of the runoff water collection container 2. The three rod-like structures may also be fixedly connected by a connecting structure to further ensure the connection stability between the three rod-like structures.

[0036] A heating belt is arranged between the first limiting cylinder 31 and the second limiting cylinder 32. Such a design effectively prevents the first limiting cylinder 31 and the second limiting cylinder 32 from freezing and causing the first limiting cylinder 31 and the second limiting cylinder 32 to be unable to rotate in a low temperature environment.

[0037] One or more thermocouples 6 are arranged on the surface of the component to be tested 100. In this design, by setting the thermocouples 6, the surface temperature change of the component to be tested 100 during the icing test is obtained. The number of thermocouples 6 can be set according to the size of the component to be tested 100. The multiple thermocouples 6 are preferably evenly distributed on the surface of the component to be tested 100 to obtain more accurate surface temperature change data of the component to be tested 100.

[0038] A second weight sensor is provided at the bottom of the runoff water collection container 2. With such a design, by providing the second weight sensor, the weight change of ice accumulation in the runoff water collection container 2 can be obtained in real time.

[0039] A heat-insulating layer is arranged outside the angle adjustment component 3. By arranging the heat-insulating layer, it is prevented that droplets enter the gaps between the components in the angle adjustment component 3 and affect the measurement structure.

[0040] The number of the limiting through holes 32-1 and the limiting blind holes 31-1 are both 12 and are evenly distributed along the circumference of the first limiting cylinder 31. With such a design, the relative position of the first limiting cylinder 31 and the second limiting cylinder 32 can be adjusted every 30°, and a group of 30° can cover the inclination angles of most ship superstructure surface structures.

[0041] The limiting blind hole 31-1 is a threaded hole. Such a design facilitates the circumferential limiting of the first limiting cylinder 31 and the second limiting cylinder 32 by bolts, that is, the limiting member 9 is a bolt, which effectively prevents the limiting member 9 from falling off and causing circumferential displacement between the first limiting cylinder 31 and the second limiting cylinder 32, thereby ensuring the structural stability of the angle adjustment assembly 3 during the icing test. The aperture of the limiting through hole 32-1 is slightly larger than the threaded aperture of the limiting blind hole 31-1, so that the bolt can pass through the limiting through hole 32-1. The aperture of the limiting through hole 32-1 needs to ensure that the bolt rod can pass smoothly and the bolt head is axially limited.

[0042] The component to be tested 100 and the second limiting cylinder 32 are fixedly connected by the mounting tube 7. With such a design, the mounting tube 7 and the component to be tested 100 and the mounting tube 7 and the second limiting cylinder 32 can be pluggable structures, which is convenient for the installation and disassembly between the component to be tested 100 and the second limiting cylinder 32, so as to more conveniently replace the component to be tested 100, and then cover the icing test of components at different positions on the ship superstructure, and obtain the icing amount in more icing scenes. The pluggable structure can be provided with protrusions that are radially telescopic at both ends of the mounting tube 7, and the limiting short tubes are fixed on the component to be tested 100 and the second limiting cylinder 32, and the through holes corresponding to the protrusions on the mounting tube 7 are opened on the wall of the limiting short tube.

[0043] The lifting bracket 1 includes two triangular brackets 12, each of which is vertically installed with a guide rail, and the crossbeam 11 is installed between the two guide rails to slide up and down. In this design, by setting the triangular brackets 12, the overall structural stability of the lifting bracket 1 is improved, and by setting the guide rail, the up and down movement of the crossbeam 11 is achieved, thereby achieving the adjustment of the height position of the component to be tested 100 during the icing test. The connection structure between the crossbeam 11 and the guide rail is a mature existing technology, which can realize the stop of the crossbeam 11 at any position in the length direction of the guide rail and the sliding along the length direction of the guide rail. The specific structure will not be repeated here.

[0044] The outer cover of the guide rail is provided with a protective cover 8. Such a design effectively avoids ice formation at the connection between the guide rail and the crossbeam 11 during the test by providing the protective cover 8, thereby ensuring that the test process proceeds smoothly.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
