Description

A forward scattering visibility meter for ice cloud distribution analysis Technical Field

[0001] This application relates to the field of meteorological monitoring equipment technology, and in particular to a forward scattering visibility meter for ice cloud distribution analysis. Background Technology

[0002] When analyzing ice cloud distribution in high-altitude areas, forward scattering visibility meters are crucial for acquiring relevant data. Therefore, forward scattering visibility meters are typically equipped with a support frame and a height adjustment mechanism. Part of the support frame is buried in the soil to provide stable support for the meter. During installation, the angle of the forward scattering visibility meter is measured, tested, and fixed. Then, the height adjustment mechanism is used to bring the meter to the target height, and the visibility in the target area is measured.

[0003] However, the unique natural environment of the plateau region presents some challenges to the stable operation of the instrument. On the one hand, the plateau region experiences strong winds, and ordinary supports are unable to withstand the onslaught of strong winds, causing the instrument to sway or even tip over, affecting measurement accuracy and equipment safety. On the other hand, the plateau has complex terrain and poor ground stability, and traditional support structures cannot adapt well to different geological conditions, making it difficult to ensure the long-term stable operation of the instrument. Summary of the Invention

[0004] This application provides a forward scattering visibility meter for ice cloud distribution analysis, which solves the problem that conventional supports are difficult to provide stable support for forward scattering visibility meters.

[0005] This application provides a forward scattering visibility meter for ice cloud distribution analysis, including a forward scattering visibility meter body and a support for supporting the visibility meter body. The support includes an alloy truss and a height adjustment mechanism. The height adjustment mechanism is disposed on the upper side of the alloy truss, and the forward scattering visibility meter is disposed on the height adjustment mechanism. It also includes a support base, metal sleeves, fixed columns, and a base plate. The support base is made of concrete. The metal sleeves are partially fixed inside the support base, and there are at least three metal sleeves, which are coaxially arranged. The base plate is disposed on the upper side of the metal sleeves, and the bottom of the support is fixedly disposed on the base plate. There are at least three fixed columns, which correspond one-to-one with at least three metal sleeves. The top of the fixed column is fixedly connected to the base plate, and the bottom end of the fixed column extends into the corresponding metal sleeve.

[0006] The support structure in this application adopts an alloy truss and height adjustment mechanism. The alloy truss structure is based on the principle of triangular stability, and the combination of welding and bolting at each node ensures the high strength and stability of the support as a whole. It can effectively resist harsh environments such as strong winds in plateau areas, reduce instrument sway, and provide stable support for accurate instrument measurement. The height adjustment mechanism can flexibly adjust the instrument height according to different measurement needs and terrain, improving the applicability of the equipment.

[0007] The coordinated design of the support base, metal sleeve, fixing column, and base plate, with the metal sleeve integrally molded with concrete, the fixing column securely connected to the metal sleeve, and the base plate supporting the bracket, ensures a tight and stable support structure. This further enhances the stability of the equipment in complex high-altitude environments, ensuring long-term reliable operation. Simultaneously, this structural design facilitates the installation and disassembly of the equipment, simplifying subsequent maintenance and repair.

[0008] In some embodiments of this application, three metal sleeves and fixing posts are provided. Three metal sleeves and fixing posts can effectively prevent the base plate from tilting or deforming under external forces, thereby providing a more stable support foundation for the bracket and forward scattering visibility meter, further enhancing the stability of the entire device in harsh high-altitude environments, and ensuring the accuracy and reliability of the instrument's measurement data.

[0009] In some embodiments of this application, the length of the metal sleeve extending to the top of the support base is less than 0.5 meters. This height can prevent excessive leverage caused by the metal sleeve extending too far when subjected to external forces (such as strong winds, collisions, etc.), which could damage components such as the metal sleeve, fixed column, or base plate, affecting the stability and service life of the equipment. Reasonably controlling the extension length of the metal sleeve can enhance the structural resistance to external damage while ensuring the stability of the connection, thereby improving the safety and durability of the equipment.

[0010] In some embodiments of this application, the fixing column and the base plate are fixed by welding. Welding connection can form a strong integrated structure with high connection strength and reliability; compared with other detachable connection methods, welding fixation avoids the problem of unstable support structure caused by loosening of the connector.

[0011] In some embodiments of this application, a limiting component is further provided between the fixed post and the metal sleeve. The limiting component includes a limiting hole provided on the fixed post along the axial direction perpendicular to the fixed post, a strip hole provided on the metal sleeve and communicating with the limiting hole, and a limiting post passing through the limiting hole and the strip hole.

[0012] The limiting component can effectively prevent the fixed column from moving axially or radially within the metal sleeve when the equipment is subjected to external forces, further enhancing the stability of the connection between the fixed column and the metal sleeve, thereby improving the stability of the entire support structure; at the same time, the setting of the strip hole can also allow the fixed column to make small-range fine adjustments to a certain extent, in order to adapt to errors during the installation process and different terrain conditions, improving the convenience and applicability of equipment installation.

[0013] In some embodiments of this application, a limiting component is provided between each fixed column and its corresponding metal sleeve. This method can comprehensively limit and reinforce all connection points between the fixed columns and the metal sleeves, avoiding the problem of decreased stability of the entire support structure due to the lack of limiting at some connection points. Through this all-round limiting design, the support structure composed of the base plate, fixed columns, and metal sleeves can maintain good stability in all directions, effectively resisting the complex and variable external forces in high-altitude areas.

[0014] In some embodiments of this application, the limiting post is a threaded post and a nut, the threaded post passes through the limiting hole and the strip hole, and at least two nuts are provided, with at least one nut provided at each end of the threaded post.

[0015] The tightening action of the nuts ensures reliable fastening and positioning of the fixed post and the metal sleeve. The use of multiple nuts increases the reliability of the connection. Even if one nut becomes loose due to long-term use or external force, the other nuts can still ensure the fastening effect of the positioning post and prevent it from falling off.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines, the terms "connected" and "linked" as used in this application have the meaning of establishing electrical connection. The specific meaning needs to be understood in conjunction with the context.

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0025] When analyzing ice cloud distribution in high-altitude areas, forward scattering visibility meters are crucial for acquiring relevant data. Therefore, forward scattering visibility meters are typically equipped with a support frame and a height adjustment mechanism. Part of the support frame is buried in the soil to provide stable support for the meter. During installation, the angle of the forward scattering visibility meter is measured, tested, and fixed. Then, the height adjustment mechanism is used to bring the meter to the target height, and the visibility in the target area is measured.

[0026] However, the unique natural environment of the plateau region presents some challenges to the stable operation of the instrument. On the one hand, the plateau region experiences strong winds, and ordinary supports are unable to withstand the onslaught of strong winds, causing the instrument to sway or even tip over, affecting measurement accuracy and equipment safety. On the other hand, the plateau has complex terrain and poor ground stability, and traditional support structures cannot adapt well to different geological conditions, making it difficult to ensure the long-term stable operation of the instrument.

[0027] Therefore, referring to Figure 1, this application provides a forward scattering visibility meter for ice cloud distribution analysis, including a forward scattering visibility meter body 1 and a support 2 for supporting the visibility meter body.

[0028] Please refer to Figure 1. The support 2 includes an alloy truss 21 and a height adjustment mechanism 22. The height adjustment mechanism 22 is disposed on the upper side of the alloy truss 21, and the forward scattering visibility meter is disposed on the height adjustment mechanism 22.

[0029] The alloy truss 21 can be made of titanium alloy (such as TC4 titanium alloy) or special stainless steel (such as 316L stainless steel). The alloy truss 21 can be constructed into a truss structure based on the principle of triangular stability. It consists of columns, beams, diagonal braces and other components, and each component is fixed by a combination of welding and bolting.

[0030] As the main supporting structure of bracket 2, alloy truss 21 bears the weight of forward scattering visibility meter, height adjustment mechanism 22 and its own weight, while resisting external wind force, vibration and other forces to maintain a stable measurement environment for the instrument.

[0031] Referring to Figure 1, the main components of the height adjustment mechanism 22, such as hydraulic cylinders and piston rods, can be made of high-strength alloy steel (such as 42CrMo alloy steel). The external protective components can be made of the same titanium alloy or special stainless steel as the alloy truss 21 to enhance the overall corrosion resistance and protective performance. The height adjustment mechanism 22 can adopt an electric hydraulic lifting system, which mainly consists of a hydraulic pump station, hydraulic cylinders, piston rods, electric control system, etc.

[0032] The electric control system of the height adjustment mechanism 22 can be equipped with a remote control module, such as one that supports wireless communication protocols (e.g., 4G, 5G), enabling remote operation. Simultaneously, the system can be equipped with a safety locking device, such as a mechanical pin-type locking mechanism, which automatically inserts into the positioning hole after the bracket 2 is adjusted to the correct height, securely locking the bracket 2 and preventing changes in the height of the bracket 2 due to external force or system malfunction.

[0033] The height adjustment mechanism 22 enables flexible height adjustment of the forward scattering visibility meter to adapt to different measurement needs (such as measuring the distribution of ice clouds at different altitudes) and complex terrain conditions on the plateau, ensuring that the instrument is in the optimal measurement position.

[0034] The hydraulic pump station, hydraulic cylinder and other components of the height adjustment mechanism 22 are fixed to a specific mounting platform on the upper side of the alloy truss 21 by bolts. The mounting platform is welded from plates of the same material as the alloy truss 21, with a flat surface and pre-drilled mounting holes that match the components of the height adjustment mechanism 22. It is connected by high-strength bolts to ensure a firm and reliable connection and to withstand various forces generated during the height adjustment process.

[0035] Referring to Figure 1, the forward scattering visibility meter can be fixed to the top of the piston rod of the height adjustment mechanism 22 by a dedicated mounting bracket 2. The mounting bracket 2 adopts a metal structural component that matches the instrument and is connected to the top of the piston rod by bolts or clips. At the same time, a shock-absorbing rubber pad is set to reduce the impact of vibration generated during height adjustment on the measurement accuracy of the instrument.

[0036] During the connection process, it is necessary to ensure that the instrument is installed in the correct position and that the transmitter and receiver are oriented in accordance with the measurement requirements, so as to ensure that the instrument can measure the relevant data on ice cloud distribution normally and accurately.

[0037] The forward scattering visibility meter for ice cloud distribution analysis also includes a support base 3, a metal sleeve 4, a fixed column 5, and a base plate 6.

[0038] Please refer to Figure 1. The support base 3 is made of concrete. The overall shape of the support base 3 can be designed as an inverted cone, with a wide bottom and a relatively narrow top. This inverted cone design can significantly increase the contact area between the support base 3 and the ground. According to the principle of pressure, when the pressure is constant, increasing the force-bearing area can reduce the pressure, thereby making the support base 3 more firmly rooted in the ground, effectively reducing the pressure per unit area, and reducing the risk of settlement of the support base 3.

[0039] Meanwhile, the inverted cone structure can better disperse stress when subjected to external forces (such as strong winds, vibrations generated by instrument operation, etc.), so that the force is evenly transmitted to the ground, enhance the ability of the support base 3 to resist external forces, prevent the support base 3 from tilting or being damaged due to excessive local stress, and provide a solid and stable foundation for the entire forward scattering visibility meter.

[0040] The concrete support base 3 can be made of precast concrete or cast in a concrete pour.

[0041] Referring to Figure 1, the metal sleeve 4 is partially fixed inside the support base 3. There are at least three metal sleeves 4, which are coaxially arranged. The metal sleeve 4 is not completely exposed, but a portion is embedded inside the concrete of the support base 3. This fixing method allows the metal sleeve 4 to form a tight connection with the support base 3.

[0042] During the concrete pouring process, the metal sleeve 4 interlocks with the concrete, using the concrete's enveloping and adhesive forces to firmly fix the metal sleeve 4 in place. In this way, the metal sleeve 4 can stably bear the load transmitted from the upper fixed column 5, the base plate 6, and the bracket 2, and evenly distribute it to the entire support base 3, effectively enhancing the stability of the support structure.

[0043] Meanwhile, the partially embedded design can also protect the metal sleeve 4, reduce its direct damage from external environmental factors (such as wind and sand erosion, collisions, etc.), and extend its service life.

[0044] Three or more support points can form a stable planar support structure. When the three metal sleeves 4 are distributed in a triangle, according to the principle of triangle stability, the force on the base plate 6 can be evenly distributed, avoiding tilting or deformation of the base plate 6 due to uneven force distribution. Even under the action of complex external forces such as strong winds and vibrations in high-altitude areas, the coordinated work of multiple metal sleeves 4 can ensure the stability of the base plate 6, thereby providing a solid support foundation for the bracket 2 and the forward-scattering visibility meter.

[0045] The coaxial arrangement means that the central axis of each metal sleeve 4 is on the same straight line. This precise positional design can ensure the consistency and stability of the force direction after the fixed column is inserted into the metal sleeve 4.

[0046] When the support 2 and the instrument are subjected to external force, the coaxially arranged metal sleeve 4 can transmit the force to the inside of the support 3 more evenly, avoid torque or eccentric force, and prevent local stress concentration between the metal sleeve 4 and the support 3 from causing damage.

[0047] Meanwhile, the coaxial arrangement also facilitates the installation and calibration of the fixed column 5, ensuring that the base plate 6 is installed horizontally, thereby enabling the bracket 2 to be installed vertically and stably on the base plate 6, ensuring that the forward scattering visibility meter is in the correct measurement position, and improving the accuracy of the measurement data.

[0048] Please refer to Figure 1. The number of metal sleeves 4 can be set to three, four, five, or other quantities.

[0049] Referring to Figure 1, the base plate 6 is set on the upper side of the metal sleeve 4, and the bottom of the bracket 2 is fixedly set on the base plate 6. As an intermediate connecting component, the base plate 6 transmits the weight of the bracket 2 and the forward-scattering visibility meter it carries, as well as the forces generated by the external environment (such as strong winds, vibrations, etc.), to the metal sleeve 4 through the fixed column, and finally distributes them into the concrete structure of the support base 3.

[0050] Because at least three metal sleeves 4 are arranged in a triangular pattern and coaxially, the force on the base plate 6 can be evenly distributed, avoiding excessive local stress that could lead to structural damage, thus ensuring the stability of the entire support structure. This effective force transmission and distribution mechanism provides a reliable support foundation for the instrument, ensuring its stable operation in complex high-altitude environments and reducing the impact of structural instability on measurement accuracy.

[0051] The precise coaxial alignment of the metal sleeve 4 provides an accurate positioning reference for the installation of the base plate 6. During installation, by accurately aligning the fixing post with the metal sleeve 4, the base plate 6 is ensured to be horizontal, thereby guaranteeing the vertical installation of the bracket 2. This is crucial for the accurate measurement of the forward-scattering visibility meter, as the instrument's transmitter and receiver need to maintain specific angles and orientations. Only with the accurate installation of the base plate 6 and bracket 2 can the accuracy and reliability of the instrument's measurement data be guaranteed.

[0052] The base plate 6 is connected to the metal sleeve 4 via a fixing post. The bottom end of the fixing post extends into the metal sleeve 4 and is fixed by a limiting component 7. This connection method not only ensures a firm connection between the fixing post and the metal sleeve 4 and prevents the fixing post from moving axially or radially within the metal sleeve 4, but also allows for some fine-tuning to accommodate errors during installation and different terrain conditions.

[0053] The limiting post 73 adopts the form of threaded post 731 and nut 732. By tightening nut 732, the fixed post and metal sleeve 4 can be reliably fastened and limited. Even if one nut 732 is loose, the other nuts 732 can still ensure the fastening effect of the limiting post 73 and ensure the stability of the connection.

[0054] Please refer to Figure 1. The bottom of the bracket 2 is fixed to the base plate 6 by means of bolt connection or welding.

[0055] Specifically, mounting holes matching the bottom connecting parts of the bracket 2 are pre-set on the base plate 6, and the bottom of the bracket 2 is tightly fixed to the base plate 6 with high-strength bolts to ensure that the bracket 2 can be stably installed on the base plate 6 and can withstand the weight of the bracket 2 and the instrument as well as external forces.

[0056] If welding is used, the welding quality must be guaranteed to ensure that the weld is uniform, full, and free from defects such as porosity and slag inclusions, so as to form a strong connection and make the bracket 2 and the base plate 6 a whole, together providing stable support for the instrument.

[0057] The base plate 6 can be made of high-strength metal materials, such as the same titanium alloy or special stainless steel as the bracket 2. These materials are characterized by high strength and corrosion resistance, enabling long-term use in harsh high-altitude climates, ensuring the structural strength and stability of the base plate 6, and preventing the performance of the entire support structure from being affected by material corrosion or damage. At the same time, metal materials have good processing properties, making it easy to process them into suitable shapes and sizes according to design requirements, meeting the connection needs with the fixed columns and bracket 2.

[0058] The fixing column can also be made of high-strength metal to ensure it can withstand large loads. Its material properties must match those of the base plate 6 and the metal sleeve 4 to guarantee the strength and reliability of the connection. In practical applications, the appropriate specifications and materials of the fixing column can be selected based on specific load calculations and design requirements to ensure that it does not deform or break during force transmission.

[0059] Please refer to Figure 1. There are at least three fixing posts, and each of the at least three fixing posts corresponds to at least three metal sleeves 4. The top of the fixing post is fixedly connected to the base plate 6, and the bottom of the fixing post extends into the corresponding metal sleeve 4.

[0060] The top of the fixed column is fixedly connected to the base plate 6, and the bottom end extends into the metal sleeve 4. This connection method creates a continuous force transmission path. The weight of the support 2 and the forward-scattering visibility meter it carries, as well as the forces generated by the external environment (such as strong wind loads, vibration and impact forces, etc.), are first transmitted to the base plate 6 through the support 2; then, the base plate 6 evenly distributes these forces to each fixed column; finally, the fixed columns transmit the force to the metal sleeve 4, and the force is distributed to the concrete structure of the support base 3 through the metal sleeve 4.

[0061] Referring to Figure 1, because the metal sleeve 4 is fixed inside the support base 3, it can effectively diffuse the force into a wider area of ​​concrete, avoiding localized stress concentration and ensuring the stability and reliability of the entire support structure. This efficient force transmission mechanism allows the equipment to maintain structural stability even when subjected to large external forces, ensuring the normal operation of the instrument and measurement accuracy.

[0062] The fixed connection between the top of the fixed column and the base plate 6, as well as the fit between the bottom end and the metal sleeve 4, significantly enhances the connection strength of the entire support structure.

[0063] The top of the fixed column and the base plate 6 can be connected by welding, high-strength bolts or other methods to form a solid integrated structure, ensuring that it can withstand a large load; the bottom end of the fixed column extends into the metal sleeve 4 and is fixed by the limiting components 7 (such as limiting hole 71, strip hole 72 and limiting post 73) to prevent the fixed column from moving axially or radially in the metal sleeve 4, and further improve the stability of the connection.

[0064] The fixing column can be a hollow column or a solid column; the length of the fixing column can be less than the depth of the cavity inside the metal sleeve 4, so that the base plate 6 overlaps the top of the metal sleeve 4. At this time, it is necessary to ensure the flatness of the top surface of the metal sleeve 4, for example, by setting an abutment plane.

[0065] Referring to Figure 1, the support 2 in this application adopts the design of an alloy truss 21 and a height adjustment mechanism 22. The alloy truss 21 structure is based on the principle of triangular stability, and the combination of welding and bolt connection at each node ensures the high strength and stability of the support 2 as a whole. It can effectively resist harsh environments such as strong winds in plateau areas, reduce instrument shaking, and provide stable support for accurate instrument measurement. The height adjustment mechanism 22 can flexibly adjust the instrument height according to different measurement needs and terrain, improving the applicability of the equipment.

[0066] Referring to Figure 1, the support base 3, metal sleeve 4, fixing column 5, and base plate 6 are arranged in a coordinated manner. The metal sleeve 4 is integrally formed with concrete, the fixing column 5 is securely connected to the metal sleeve 4, and the base plate 6 supports the bracket 2. This ensures a tight and stable connection of the entire support structure, further enhancing the stability of the equipment in complex high-altitude environments and ensuring long-term reliable operation of the instrument. Simultaneously, this structural design facilitates the installation and disassembly of the equipment, making subsequent maintenance and repair work easier.

[0067] Referring to Figure 1, in some examples, three metal sleeves 4 and fixing posts are provided. Three metal sleeves 4 and fixing posts effectively prevent the base plate 6 from tilting or deforming under external forces, thus providing a more stable support foundation for the bracket 2 and the forward scattering visibility meter. This further enhances the stability of the entire device in harsh high-altitude environments and ensures the accuracy and reliability of the instrument's measurement data.

[0068] In some other examples, the metal sleeve 4 and the fixing post can also be set to four.

[0069] Referring to Figure 1, in some examples, the metal sleeve 4 extends less than 0.5 meters to the top of the support base 3. This height prevents excessive extension of the metal sleeve 4 from generating a large lever effect under external forces (such as strong winds or collisions), which could damage components such as the metal sleeve 4, the fixed column 5, or the base plate 6, affecting the stability and service life of the equipment. Properly controlling the extension length of the metal sleeve 4 ensures the stability of the connection while enhancing the structure's resistance to external forces, thus improving the safety and durability of the equipment.

[0070] For example, the extension length of the metal sleeve 4 at the top of the support base 3 can be between 0.2m and 0.4m, and the length of the fixing column can be between 0.4m and 0.7m.

[0071] Referring to Figure 1, in some examples, the fixing column and the base plate 6 are fixed by welding. Welding connection can form a strong integrated structure with high connection strength and reliability; compared with other detachable connection methods, welding fixation avoids the problem of unstable support structure caused by loosening of the connecting parts.

[0072] In some other examples, the fixing post and the base plate 6 can be integrally formed or threaded together.

[0073] Referring to Figures 1 and 2, in some examples, a limiting component 7 is also provided between the fixed post and the metal sleeve 4. The limiting component 7 includes a limiting hole 71 provided on the fixed post along the axis perpendicular to the fixed post, a strip hole 72 provided on the metal sleeve 4 and communicating with the limiting hole 71, and a limiting post 73 passing through the limiting hole 71 and the strip hole 72.

[0074] Referring to Figure 2, the limiting component 7 can effectively prevent the fixed column from moving axially or radially within the metal sleeve 4 when the equipment is subjected to external forces, further enhancing the stability of the connection between the fixed column and the metal sleeve 4, thereby improving the stability of the entire support structure; at the same time, the setting of the strip hole 72 can also allow the fixed column to have a small range of fine adjustment to adapt to errors during the installation process and different terrain conditions, improving the convenience and applicability of equipment installation.

[0075] Referring to Figure 2, in some examples, a limiting component 7 is provided between each fixed post and its corresponding metal sleeve 4. This method can comprehensively limit and reinforce all connection points between the fixed posts and the metal sleeve 4, avoiding the problem of decreased stability of the entire support structure due to the lack of limiting at some connection points. Through this comprehensive limiting design, the support structure composed of the base plate 6, fixed posts, and metal sleeve 4 can maintain good stability in all directions, effectively resisting the complex and variable external forces in high-altitude areas.

[0076] Referring to Figure 2, in some examples, the limiting post 73 is a threaded post 731 and a nut 732. The threaded post 731 passes through the limiting hole 71 and the strip hole 72. The nuts 732 are provided in at least two and each end of the threaded post 731 is provided with at least one nut 732.

[0077] The tightening action of the nut 732 can reliably fasten and limit the fixed post and the metal sleeve 4; the setting of multiple nuts 732 increases the reliability of the connection. Even if one nut 732 becomes loose due to long-term use or external force, the other nuts 732 can still ensure the fastening effect of the limiting post 73 and prevent the limiting post 73 from falling off.

[0078] In other examples, the limiting post 73 can be fixed by rivets or other non-removable structures to ensure the limiting effect.

[0079] In some examples, the limiting component 7 between each set of fixed posts and the corresponding metal sleeve 4 can be set as one set, or as two sets or other numbers of sets.

[0080] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0081] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
