An angle-adjustable component icing measurement and runoff collection device

Abstract

An angle-adjustable component icing measurement and runoff water collection device belongs to the technical field of icing and anti-icing research on ships and marine structures. This invention solves the problem in existing droplet icing measurement devices where the height and angle of the component under test cannot be adjusted, thus failing to cover most components on the ship's superstructure surface for icing testing. The component under test is mounted on the top of a lifting support via an angle adjustment component, and its height is adjusted via the lifting support. A limiting element is inserted into corresponding limiting through holes and blind holes to achieve circumferential limiting between two limiting cylinders, with the component under test fixed to the second limiting cylinder. This allows for changes in the angle and height of the component under test, enabling the acquisition of icing conditions at different windward positions on the ship's superstructure. It overcomes the limitation of traditional icing devices that can only simulate flow from a single direction, avoids the need for multiple component replacements, and effectively improves experimental efficiency.

Description

Technical Field

[0001] This invention relates to an angle-adjustable component icing measurement and runoff water collection device, belonging to the technical field of icing and anti-icing research on ships and marine structures. Background Technology

[0002] Ships and marine structures are highly susceptible to icing when navigating or operating in low-temperature waters, with ice accumulation reaching hundreds of tons. Ice buildup not only reduces ship stability but also freezes deck equipment, disrupting normal operations and, in severe cases, threatening the lives of personnel on board. Icing of ship and marine structure superstructures is primarily caused by droplet freezing. Large amounts of wind-generated or wave-generated droplets move under the influence of wind and their own gravity, with some freezing upon impact with the structural surface. The components of the ship's superstructure are mainly plates, which have various angles. Different angles of plates receive different amounts of droplets, resulting in varying final ice accumulation. Therefore, it is necessary to develop a seawater droplet icing experimental device to investigate the icing mechanism of ship superstructure surface plates, thereby understanding the freezing and runoff mechanisms of droplets impacting different types of structures. This will provide data support and scientific guidance for improving the accuracy of ship icing forecasting methods and developing more efficient anti-icing and de-icing technologies.

[0003] Existing seawater droplet icing devices mostly use fixed, vertical cylinders as icing components, which cannot simulate the icing process on the numerous inclined structural surfaces of a ship's superstructure. Furthermore, the droplet diameter and velocity vary at different heights within seawater droplet clusters, thus affecting the amount of icing. Fixed icing components can only measure the amount of icing at a specific height, limiting their application. Therefore, there is an urgent need for an adjustable-angle component icing measurement and runoff collection device, allowing the icing component to rotate at different angles and adjust to different heights, covering most components on the surface of a ship's superstructure.

[0004] There are other devices in other technical fields that can automatically adjust the angle, but these devices generally require a drive structure and electrical circuits to control the rotation angle. When applied to icing tests, they are prone to icing of the rotation position, drive structure and / or electrical circuits, which can lead to inoperability. Therefore, existing devices that can automatically adjust the angle are not suitable for seawater droplet icing tests. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems and provides an angle-adjustable component icing measurement and runoff water collection device.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] An angle-adjustable component icing measurement and runoff collection device includes a lifting support, a runoff collection container, and an angle adjustment assembly. The lifting support is installed inside the runoff collection container, and the component to be measured is mounted on top of the lifting support via the angle adjustment assembly, allowing for height-direction position adjustment.

[0008] The angle adjustment assembly includes a first limiting cylinder and a second limiting cylinder coaxially fitted from the inside out.

[0009] The first limiting cylinder is a cylindrical structure with an outer circle and an inner square, the second limiting cylinder is a cylindrical structure, and the crossbeam of the lifting support is a rectangular tubular structure or a rectangular rod structure. The first limiting cylinder is fitted onto the crossbeam, and a first weight sensor is provided between the top inner wall of the first limiting cylinder and the top of the crossbeam.

[0010] The first limiting cylinder has several limiting blind holes distributed along its circumference, and each limiting blind hole is radially opened along the first limiting cylinder. The second limiting cylinder has several limiting through holes distributed along its circumference, and the limiting blind holes and limiting through holes are arranged in a one-to-one correspondence along the radial direction of the second limiting cylinder. Circumferential limiting between the two limiting cylinders is achieved by inserting limiting elements into the corresponding limiting through holes and limiting blind holes.

[0011] The component to be tested is fixedly mounted on the second limiting cylinder.

[0012] Furthermore, a heat tracing cable is provided between the first limiting cylinder and the second limiting cylinder.

[0013] Furthermore, one or more thermocouples are arranged on the surface of the component to be tested.

[0014] Furthermore, a second weight sensor is installed at the bottom of the runoff collection container.

[0015] Furthermore, the angle adjustment component is externally provided with an insulation layer.

[0016] Furthermore, there are 12 limiting through holes and 12 limiting blind holes, which are evenly distributed along the circumference of the first limiting cylinder.

[0017] Furthermore, the limiting blind hole is a threaded hole.

[0018] Furthermore, the component to be tested is fixedly connected to the second limiting cylinder through an installation tube.

[0019] Furthermore, the lifting support includes two triangular supports, each of which is vertically mounted with a guide rail, and the crossbeam is slidably mounted between the two guide rails.

[0020] Furthermore, a protective cover is provided on the outer side of the guide rail.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] In this invention, an angle adjustment component is set up to raise and lower the support, thereby realizing the angle and height changes of the component under test. This allows for the acquisition of icing conditions at different windward positions in the superstructure of a ship, solving the problem that traditional icing devices can only simulate flow in a single direction (horizontal direction). It also avoids the need to replace the component under test multiple times, effectively improving the efficiency of the test.

[0023] The angle-adjustable component icing measurement and runoff water collection device of the present invention can be applied to icing tests of typical ship structures. It can collect icing information (such as ice thickness) of the component under test under specific icing conditions, wherein the component under test can be a cylinder or plate or other typical components of ship superstructure.

[0024] The angle-adjustable component icing measurement and runoff water collection device of the present invention has an angle adjustment component that is manually adjustable, which is simple and convenient to operate. In low-temperature environments, the components of the angle adjustment component are not easily damaged, making it more suitable for seawater droplet icing tests.

[0025] A first weight sensor is installed between the first limiting cylinder and the crossbeam to measure the change in the amount of ice on the surface of the component under test during the icing test. Attached Figure Description

[0034] Specific implementation method one: Combining Figures 1-2This description of embodiments provides a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should be noted that the descriptions of "front," "rear," "left," "right," "inner," "outer," "left side," "right side," "upper part," "lower part," "top," and "bottom" in this invention are defined based on the orientation or positional relationships shown in the accompanying drawings. They are merely for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the described structure must be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] In the description of this invention, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] An angle-adjustable component icing measurement and runoff collection device includes a lifting support 1, a runoff collection container 2, and an angle adjustment assembly 3. The lifting support 1 is installed inside the runoff collection container 2. The component to be measured 100 is mounted on the top of the lifting support 1 via the angle adjustment assembly 3, and its height can be adjusted via the lifting support 1.

[0038] The angle adjustment assembly 3 includes a first limiting cylinder 31 and a second limiting cylinder 32 coaxially mounted from the inside out.

[0039] The first limiting cylinder 31 is a cylindrical structure with an outer circle and an inner square, the second limiting cylinder 32 is a cylindrical structure, and the crossbeam 11 of the lifting bracket 1 is a rectangular tubular structure or a rectangular rod structure. The first limiting cylinder 31 is fitted onto the crossbeam 11, and a first weight sensor 4 is provided between the top inner wall of the first limiting cylinder 31 and the top of the crossbeam 11.

[0040] The first limiting cylinder 31 has several limiting blind holes 31-1 distributed along its circumference, and each limiting blind hole 31-1 is radially opened along the first limiting cylinder 31. The second limiting cylinder 32 has several limiting through holes 32-1 distributed along its circumference, and the limiting blind holes 31-1 and the limiting through holes 32-1 are arranged in a one-to-one correspondence along the radial direction of the second limiting cylinder 32. By inserting limiting elements 9 into the corresponding limiting through holes 32-1 and limiting blind holes 31-1, circumferential limiting between the two limiting cylinders is achieved.

[0041] The component to be tested, 100, is fixedly mounted on the second limiting cylinder, 32.

[0042] The test component 100 is mounted on the lifting bracket 1 at a certain angle using the angle adjustment component 3. The bottom end of the test component 100 is set higher than the runoff collection container 2 to avoid the side wall of the runoff collection container 2 affecting the droplet impact on the test component 100, thereby improving the accuracy of the icing test structure.

[0043] During the test, some droplets will form a water film after hitting the surface of the test component 100. Some of the water in the water film will flow downward under the action of gravity and detach from the surface of the test component 100, forming runoff. The runoff is collected by setting up a runoff collection container 2.

[0044] The outer wall of the first limiting cylinder 31 and the inner wall of the second limiting cylinder 32 are both circular and fit together. By using the inner hole of the first limiting cylinder 31 with a rectangular cross-section and the crossbeam 11 with the same rectangular cross-section, the circumferential limiting of the first limiting cylinder 31 on the crossbeam 11 can be achieved by utilizing the inherent structural advantages of the rectangular structure, eliminating the need for other circumferential limiting structures and further simplifying the structural composition of the angle adjustment component 3.

[0045] Several limiting through holes 32-1 and several limiting blind holes 31-1 are evenly distributed along the circumference.

[0046] In this invention, by setting an angle adjustment component 3 to raise and lower the support 1, the angle and height of the component under test 100 are changed, and the icing situation at different windward positions in the superstructure of the ship is obtained. This solves the problem that traditional icing devices can only simulate a single direction (horizontal direction) of incoming flow, avoids the need to replace the component under test 100 multiple times, and effectively improves the test efficiency.

[0047] The angle-adjustable component icing measurement and runoff water collection device of the present invention can be applied to icing tests of typical ship structures. It can collect icing information (such as ice thickness) of the component 100 under test under specific icing conditions. The component 100 under test can be a cylinder or plate or other typical components of ship superstructure.

[0048] The angle-adjustable component icing measurement and runoff water collection device of the present invention has an angle adjustment component 3 that is manually adjustable, which is simple and convenient to operate. In low temperature environments, the components of the angle adjustment component 3 are not easily damaged, making it more suitable for seawater droplet icing tests.

[0049] By setting a first weight sensor 4 between the first limiting cylinder 31 and the crossbeam 11, the change in the amount of ice on the surface of the component 100 under test during the icing test can be measured.

[0050] The runoff collection container 2 has a cylindrical structure.

[0051] The runoff collection container 2 is supported by a support frame 5 located at its bottom. The support frame 5 prevents the runoff collection container 2 from freezing upon contact with the ground. The support frame 5 is preferably fixedly connected to the bottom of the runoff collection container 2. The support frame 5 can consist of three rod-shaped structures evenly distributed circumferentially at the bottom of the runoff collection container 2. These three rod-shaped structures can also be fixedly connected by a connecting structure to further ensure the stability of the connection between the three rod-shaped structures.

[0052] A heat tracing cable is provided between the first limiting cylinder 31 and the second limiting cylinder 32. This design effectively prevents ice formation between the first limiting cylinder 31 and the second limiting cylinder 32 in low-temperature environments, which could prevent rotation.

[0053] One or more thermocouples 6 are arranged on the surface of the component 100 under test. With this design, the surface temperature change of the component 100 under test during the icing test can be obtained by setting the thermocouples 6. The number of thermocouples 6 can be set according to the size of the component 100 under test. It is preferable that multiple thermocouples 6 are evenly distributed on the surface of the component 100 under test to obtain more accurate surface temperature change data of the component 100 under test.

[0054] A second weight sensor is installed at the bottom of the runoff collection container 2. This design allows for real-time monitoring of changes in the weight of ice accumulation within the runoff collection container 2.

[0055] An insulation layer is provided on the outside of the angle adjustment component 3. This design, by providing an insulation layer, prevents droplets from entering the gaps between the various components of the angle adjustment component 3 and affecting the measurement structure.

[0056] The number of limiting through holes 32-1 and limiting blind holes 31-1 are both 12 and are evenly distributed along the circumference of the first limiting cylinder 31. This design allows the relative position of the first limiting cylinder 31 and the second limiting cylinder 32 to be adjusted every 30°, and each 30° group can cover the tilt angle of most ship superstructure surface structures.

[0057] The limiting blind hole 31-1 is a threaded hole. This design facilitates circumferential positioning between the first limiting cylinder 31 and the second limiting cylinder 32 using bolts. In other words, the limiting component 9 is a bolt, effectively preventing the limiting component 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 diameter of the limiting through hole 32-1 is slightly larger than the threaded hole diameter of the limiting blind hole 31-1, facilitating the bolt's passage through the limiting through hole 32-1. The diameter of the limiting through hole 32-1 needs to ensure that the bolt shank can pass smoothly while the bolt head is axially limited.

[0058] The component under test 100 is fixedly connected to the second limiting cylinder 32 via the mounting tube 7. This design allows for pluggable structures between the mounting tube 7 and the component under test 100, as well as between the mounting tube 7 and the second limiting cylinder 32. This facilitates the installation and removal of the component under test 100 and the second limiting cylinder 32, making it easier to replace the component under test 100. Furthermore, it can cover icing tests on components at different locations on the ship's superstructure, obtaining icing data from more icing scenarios. The pluggable structure can be configured by providing radially extending protrusions at both ends of the mounting tube 7, and fixing short tubes to both the component under test 100 and the second limiting cylinder 32. Through holes corresponding to the protrusions on the mounting tube 7 are formed on the walls of these short tubes.

[0059] The lifting support 1 includes two triangular supports 12, each with a vertically mounted guide rail. A crossbeam 11 is slidably mounted between the two guide rails. This design enhances the overall structural stability of the lifting support 1 by using the triangular supports 12, and allows the crossbeam 11 to move vertically, thereby adjusting the height of the component 100 under test during the icing test. The connection structure between the crossbeam 11 and the guide rails is a mature existing technology, allowing the crossbeam 11 to stop at any position along the length of the guide rails and slide along the length of the guide rails. The specific structure will not be described in detail here.

[0060] The guide rail is equipped with a protective cover 8. This design effectively prevents ice formation at the connection between the guide rail and the crossbeam 11 during the test, thus ensuring the smooth progress of the test.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
