Description

Technical Field

[0001] This utility model relates to a portable desludge release ground support device, and more specifically, to a portable desludge release ground support device capable of opening the desludge release valve of the auxiliary fuel tank in the cargo hold of an aircraft and performing desludge release maintenance work on the auxiliary fuel tank. Background Technology

[0002] The auxiliary fuel system is an important component of an aircraft. It is generally used as an additional fuel system to increase flight range, and therefore, an auxiliary fuel tank is provided in this auxiliary fuel system.

[0003] like Figure 8 As shown, the auxiliary fuel tank 2 is an additional fuel tank attached to the original aircraft's basic fuel tank. It is usually located in the cargo hold to store extra fuel. This fuel is not directly supplied to the engine, but is transferred to the basic fuel tank through the auxiliary fuel system, thereby increasing the aircraft's range.

[0004] The auxiliary fuel tank 2 requires frequent maintenance to drain sediment. This is typically done by opening the sediment drain valve 3 at the bottom of the auxiliary fuel tank 2 using ground support equipment (GSE). Figure 9 As shown, the sediment discharge valve 3 is connected to the aircraft cowling 4 via the liquid pipeline PT, thereby discharging the sediment and aqueous solution at the bottom of the fuel tank to the outside of the fuselage through the sediment discharge pipeline.

[0005] However, since the auxiliary fuel tank 2 of civil aircraft is usually located in the cargo hold of the aircraft, and the sediment drain line needs to be directly connected to the outside of the fuselage, the operator cannot directly access the sediment drain valve 3 of the auxiliary fuel tank 2. The sediment drain valve 3 can only be opened by using GSE special equipment. Furthermore, since the sediment drain valve 3 cannot be accessed, the open and closed status of the sediment drain valve 3 of the auxiliary fuel tank 2 cannot be visually confirmed. Therefore, the sediment drain valve 3 needs to be kept open at all times during the operation.

[0006] In addition, the sediment drain valve 3 is located at the bottom of the auxiliary fuel tank 2, and the sediment drain port FK is located on the surface of the engine body. Under normal circumstances, the sediment drain port FK is sealed by a plug, but under maintenance conditions, the plug is removed and the GSE device is inserted to perform sediment draining operation.

[0007] like Figure 9As shown, according to feedback from on-site operators, when performing sediment removal maintenance on auxiliary fuel tank 2 using the previous sediment removal ground support equipment (GSE) 1', the operator needs to squat under the aircraft's belly and lift the GSE equipment with their hands. The operating position is low, the operator's posture is inconvenient, the shoulder load is heavy, and the ergonomics are not good. The operator feels very tired and uncomfortable during the operation. Therefore, the sediment removal operation needs to be further optimized.

[0008] In the past, designers have tried to make a series of improvements to address this operational problem.

[0009] For example, patent CN211001873U discloses a convenient aircraft fuel tank sediment draining membrane conduit. This conduit consists of a sediment draining valve opening pin, a conical oil collecting chamber, an annular adhesive membrane, a membrane guide tube, an oil drain flare, and fixing tape. When using this convenient membrane conduit for aircraft fuel tank sediment draining maintenance, the annular adhesive membrane can be adhered to the aircraft skin surface through the protective film on its surface, avoiding prolonged hand operation.

[0010] However, the aircraft will vibrate during flight. In order to keep the valve closed, the spring clamping force of the auxiliary fuel tank's sediment discharge valve is relatively large. Since the adhesiveness of the annular adhesive film is not very strong, it cannot effectively guarantee adhesion and there is a possibility of it falling off. Therefore, the operator still needs to perform hand operation during maintenance.

[0011] In view of the shortcomings of the existing technology, how to provide a portable ground support device for sedimentation that can suspend the ground support equipment without hand operation has become an urgent technical problem to be solved. Utility Model Content

[0012] This disclosure is made to solve the above-mentioned technical problems, and its purpose is to provide a portable ground support device for draining sediment, through which ground operators can complete the maintenance operation of draining sediment from the auxiliary fuel tank without long-term hand operation.

[0013] To achieve the objectives of this disclosure, a portable descum removal ground support device is provided, which is suitable for performing descum removal maintenance operations on the auxiliary fuel tank of an aircraft. The device includes: a push rod, the push rod being rod-shaped and having a cross-sectional shape matching the shape of the descum removal valve of the auxiliary fuel tank; an oil collection section, the oil collection section having a space for accommodating fuel deposits; and a flow guide section, the flow guide section being an elongated pipe and fluidly connected at one end to the oil collection section. The portable descum removal ground support device also includes a locking part, the locking part being mechanically connected to the auxiliary fuel tank.

[0014] As described above, the portable sediment release ground support device can be connected to the auxiliary fuel tank in a mechanical manner through the locking part, with high fixing strength and a firm and reliable connection, and can complete sediment release maintenance operations without manual operation.

[0015] Preferably, the locking part includes a hook base and a hook body. The hook base is formed in a circular shape and is fixedly installed on the base of the oil collecting part. The hook body extends upward from the hook base at one end and has a bent hook at the other end. Multiple hooks are provided at equal intervals along the circumference of the hook base.

[0016] As described above, the portable sedimentation ground support equipment is connected to the aircraft fuselage through the hooks of multiple hook bodies, which can effectively ensure the connection strength and is simple in structure, easy to operate and implement.

[0017] Preferably, the hook of the hook body is bent radially inward and hooked onto the suspension hook portion formed on the outer periphery of the suspension joint.

[0018] Preferably, the suspension connector further includes a suspension fixing part and a suspension guide part. The suspension fixing part has an external thread formed on its outer periphery, which can be installed on the machine body by means of thread fixing. The suspension guide part is formed into a long and narrow groove shape so as to guide the hook body of the locking part.

[0019] As described above, in the locking part of the above form, the suspension joint is mechanically connected to the aircraft fuselage through the suspension fixing part, which can effectively ensure the connection strength. Furthermore, the movement of the hook body is guided by the suspension guide part, which facilitates the hooking operation of the locking part and thus improves the work efficiency.

[0020] Preferably, the hook of the hook body is bent radially outward and hooked onto the sedimentation hook portion formed inside the sedimentation connector.

[0021] Preferably, the aforementioned sediment discharge connector further includes a sediment discharge fixing part and a sediment discharge guiding part. The sediment discharge fixing part is formed as a flanged disc extending radially outward, which can be installed on the machine body by means of bolt fixing. The sediment discharge guiding part is formed as an elongated groove shape to guide the hook body of the aforementioned locking part.

[0022] As described above, in the locking part of the above-described form, the sediment release fixing part of the sediment release connector is formed into a disc shape, which can effectively expand the contact area with the machine body surface, thereby improving the fixing strength. Furthermore, the sediment release guide part guides the movement of the hook body, which facilitates the hooking operation of the locking part, thereby improving the work efficiency.

[0023] Preferably, the oil collection section is formed in a tapered shape that tapers from top to bottom, and includes an opening and a peripheral portion. The opening faces upward, and the peripheral portion is located at the edge of the opening and is close to the aircraft skin around the sediment drain port during sediment drain maintenance.

[0024] As described above, by forming the oil collection section into a conical shape and bringing its periphery close to the aircraft skin around the descaling port, it is possible to effectively prevent fuel deposits from splashing and polluting the environment during descaling maintenance operations.

[0025] Preferably, the aforementioned push rod is located at the center of the aforementioned oil collection section and includes a limiting part, the bottom end of the aforementioned limiting part abutting against the aforementioned hook base, and its outer periphery abutting against the aforementioned hook body.

[0026] As described above, the limiting part can effectively fix the position of the top rod, thereby effectively preventing the top rod from shifting position during the sedimentation operation and facilitating the smooth progress of the sedimentation maintenance operation.

[0027] Preferably, a flared discharge section is provided at the other end of the elongated pipe of the flow guide, and a through hole suitable for fluid flow is provided on the discharge section.

[0028] As described above, by providing a discharge section with a flared shape, the fluid flow rate at the discharge end can be effectively slowed down, thereby preventing liquid splashing and environmental pollution.

[0029] Preferably, the oil collecting section and the guide section are formed to be transparent or semi-transparent.

[0030] As described above, the operator can clearly observe the flow of fuel deposits during the desettling maintenance operation, thus facilitating the smooth progress of the desettling maintenance work. Attached Figure Description

[0067] Various embodiments of the present invention will now be described in detail, examples of which are shown in the accompanying drawings.

[0068] Although this invention has been described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the invention to the exemplary embodiments described below. Rather, the invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other embodiments that may be included within the spirit and scope of the invention as defined by the appended claims.

[0069] The following is for reference Figure 1 The overall structure of the portable sedimentation ground support device 1 of this utility model will be described. Figure 1 This is a structural schematic diagram showing the configuration 1 of the portable sedimentation ground support device 1 of this utility model.

[0070] like Figure 1 As shown, the portable sedimentation ground support device 1 of this utility model mainly includes a top rod 10, an oil collection part 20, a locking part 30A, and a flow guiding part 40.

[0071] The aforementioned push rod 10 is formed into a slender rod shape, and the cross-sectional shape of the push rod 10 matches the shape of the sludge drain valve 3 of the auxiliary fuel tank 2, including but not limited to the straight, cross, star, and polygonal shapes, so as to facilitate opening the sludge drain valve 3 of the aircraft's auxiliary fuel tank 2 during the sludge draining operation.

[0072] In addition, the aforementioned push rod 10 is generally made of non-metallic materials, preferably one of nylon, resin, polyethylene, polyester, and polyvinyl chloride as polymer materials, which can effectively prevent corrosion from aircraft fuel and thus extend its service life.

[0073] Furthermore, minute tolerances may exist during aircraft manufacturing, which could prevent a pure metal rod from passing through the liquid line to reach the settling valve and thus open it. Using a more flexible push rod would facilitate its passage through the liquid line.

[0074] The oil collecting section 20 is formed into a tapered shape that gradually narrows from top to bottom. A push rod 10 is provided at the middle position of the oil collecting section 20, and the oil collecting section 20 forms a space to accommodate fluids including oil, water, impurities, etc., so as to collect fuel sediment discharged from the sediment discharge valve 3.

[0075] The aforementioned locking part 30A is fixedly installed in the base part 23 of the oil collecting part 2 and is integrally formed with the oil collecting part 20.

[0076] By engaging with the adapter structure provided on the aircraft skin via the locking part 30A, the portable sediment release ground support device 1 of this utility model can be hooked to the bottom of the auxiliary fuel tank 2 during the sediment release operation without the need for manual operation by the operator.

[0077] The aforementioned guide portion 40 is formed as a slender pipe extending downward from the base portion 23 of the oil collection portion 2, and is integrally formed with the base portion 23, thereby effectively discharging fuel deposits from the auxiliary fuel tank 2.

[0078] Preferably, a flared discharge portion (not shown) is formed at the lower end of the aforementioned guide portion 40, thereby effectively slowing down the fluid flow rate at the discharge end.

[0079] In addition, a collection container (not shown) may be provided around the discharge section to collect the fluid discharged through the guide section 40, and an attachment device (not shown) may also be provided on the discharge section to attach the discharge section to the collection container or other fixed location.

[0080] Furthermore, preferably, the oil collecting section 20 and the flow guiding section 40 are made of flexible transparent or semi-transparent film materials, including but not limited to plastic film materials, silicone materials, nanomaterials, etc., so that operators can easily observe the discharge of fuel sediment during the sediment discharge operation, thereby reducing the incidence of accidents.

[0081] <Configuration 1>

[0082] The following is for reference Figures 2 to 4 The specific structure of the portable sedimentation ground support device 1 of configuration 1 of this utility model will be described.

[0083] like Figure 2 As shown, the portable sedimentation ground support device 1 of the present invention mainly includes a top rod 10, an oil collection part 20, a locking part 30A, and a flow guiding part 40.

[0084] The aforementioned top rod 10 is formed into a slender rod shape and is located at the center of the portable sedimentation ground support device 1.

[0085] By passing the push rod 10 through the sediment drain port FK located on the fairing 4 and through the liquid line PT to the sediment drain valve 3, the sediment drain valve 3 can be opened, thereby draining the sediment solution located in the auxiliary fuel tank 2 to the outside of the engine body through the liquid line PT.

[0086] The oil collecting part 2 mentioned above includes an opening 21, a peripheral part 22 and a base part 23 that are integrally formed.

[0087] The opening 21 is formed in the shape of a funnel that gradually narrows from top to bottom and opens upwards.

[0088] The aforementioned peripheral portion 22 is located at the edge of the opening 21, and during the desettling maintenance process, it approaches the aircraft skin around the desettling port FK and surrounds the desettling port FK inside the oil collection section 2, thereby effectively preventing fuel deposits from splashing to the outside and polluting the environment during the desettling process.

[0089] The base portion 23 is formed in a generally cylindrical shape and extends downward from the lower end of the opening portion 21.

[0090] like Figure 2 As shown, the aforementioned locking part 30A includes a hook base 31A and a hook body 32A.

[0091] The hook base 31A is formed in a generally disc shape and is fixedly installed in the base portion 23 of the oil collection portion 2. On the upper surface of the hook base 31A, a plurality of main body mounting portions for inserting the hook body 32A are provided at equal intervals along the circumference.

[0092] The hook body 32A is formed as an elongated strip extending upwards, with one end inserted and fixed to the mounting part of the main body, and the other end forming a hook that bends radially inwards.

[0093] Typically, the hook base 31A and the hook body 32A mentioned above are both made of aluminum alloy and are connected together by welding to ensure the overall structural strength.

[0094] In addition, such as Figure 2 As shown, preferably, a limiting part 11 is integrally provided on the top rod 10. The limiting part 11 is located inside the hook body 32A and is formed into a cylindrical shape that is larger than the diameter of the top rod 10.

[0095] The bottom end of the limiting part 11 abuts against the hook base 31A, thereby limiting the axial movement of the push rod 10, and its outer periphery abuts against the hook body 32A, thereby limiting the radial movement of the push rod 10, so as to fix the push rod 10 in the approximate central position of the oil collection part 20, which can prevent the push rod 10 from shifting position during the sedimentation operation and help to facilitate the smooth progress of the sedimentation maintenance operation.

[0096] Furthermore, the oil collecting part 20 is made of a transparent polymer material, and its base part 23 is connected to the hook base 31A by a high-viscosity adhesive to ensure that the oil collecting part 2 will not fall off when the locking part 30A is hooked to the bottom of the auxiliary fuel tank 2. In addition, there is a gap between the oil collecting part 20, the push rod 10 and the locking part 30A to allow fuel sediment to flow through.

[0097] Next, refer to Figure 3 and Figure 4 The suspension method of the portable sedimentation ground support device 1 of the present invention will be described.

[0098] like Figure 3 As shown, in configuration 1 of this utility model, the suspension joint XG is generally formed into a hollow cylindrical shape, which facilitates the passage of the top rod 10 and precipitated liquids such as fuel deposits.

[0099] Specifically, the aforementioned suspension joint XG mainly includes an integrally formed suspension fixing part XG1, suspension guide part XG2, and suspension hook hanging part XG3.

[0100] The aforementioned suspension fixing part XG1 is formed on the upper part of the suspension joint XG, and an external thread is formed on its outer periphery, so that the suspension fixing part XG1 can be installed on the sink outlet FK on the fuselage surface by means of threaded connection, so as to fix it to the fuselage of the aircraft.

[0101] Furthermore, the suspension fixing part XG1 can be screwed into different thread depths relative to the aircraft fuselage to accommodate the top rod length requirements of different sedimentation equipment.

[0102] The aforementioned suspension guide part XG2 and suspension hook part XG3 are formed in the lower section of the suspension joint XG, and are generally formed into an inverted "L" shaped groove. The suspension guide part XG2 is used to guide the hook body 32A of the locking part 30A, and the suspension hook part XG3 is used for the hook body 32A to be hooked.

[0103] like Figure 4 As shown, after the locking part 30A of the portable sediment draining ground support device 1 of the present invention is suspended on the suspension joint XG, the position of the oil inlet at the upper end of the opening 21 of the oil collection part 20 of the portable sediment draining ground support device 1 is higher than the position of the oil outlet at the lower end of the suspension joint XG in the vertical direction, thereby preventing the fuel sediment from splashing during the sediment draining maintenance process.

[0104] Furthermore, it is preferable to adjust the thread depth of the suspension fixing part XG1 of the suspension joint XG to ensure that the peripheral part 22 of the oil collection part 20 is in close contact with the aircraft skin around the sediment discharge port FK, thereby preventing fuel sediment from splashing into the external environment as much as possible.

[0105] <Operating steps for configuration 1>

[0106] The following describes the specific operating steps for performing sediment removal maintenance on the auxiliary fuel tank 2 using the portable sediment removal ground support device 1 of configuration 1 of this utility model.

[0107] Step 1: Remove the plug at the sediment discharge port FK located on the outer surface of the fairing 4;

[0108] Step 2: Install the suspension connector XG of configuration 1 of this utility model onto the above-mentioned sediment discharge port FK;

[0109] Step 3: Insert the top rod 10 of the portable sediment discharge ground support device 1 of configuration 1 of this utility model into the sediment discharge valve 3 through the sediment discharge port FK, and confirm the lifting height of the sediment discharge valve 3;

[0110] Step 4: Rotate the suspension joint XG to adjust the lifting height;

[0111] Step 5: Suspend and install the above-mentioned portable sediment release ground support device 1 on the suspension connector XG. Specifically, align the hook body 32A of the locking part 30A with the suspension guide part XG2 of the suspension connector XG and insert it upwards. After inserting it to the top, rotate the locking part 30A and suspend the hook body 32A on the suspension hook hanging part XG3 of the suspension connector XG, ensuring that the fuel deposits can flow out from the sediment release valve 3 through the portable sediment release ground support device 1 of this utility model to the outside.

[0112] Step 6: After all the fuel deposits in the auxiliary fuel tank 2 have flowed out, move the hook body 32A upward and rotate it so that it slides downward along the suspension guide XG2 so as to remove the suspension connector XG and the top rod 10.

[0113] Step 7: Remove the above-mentioned suspension connector XG from the sediment discharge port FK;

[0114] Step 8: Reinstall the plug on the sediment discharge port FK to complete the sediment discharge operation.

[0115] As mentioned above, after completing step five, ground operators no longer need to hold the sedimentation support equipment (GSE) continuously, which significantly reduces workload, labor intensity, and work efficiency, thereby facilitating the smooth progress of sedimentation prevention maintenance operations.

[0116] <Configuration 2>

[0117] The following is for reference Figures 5 to 7 The specific structure of the portable sedimentation ground support device 1 of configuration 2 of this utility model will be described.

[0118] like Figure 5 As shown, similar to the portable sedimentation ground support device 1 of configuration 1, the portable sedimentation ground support device 1 of configuration 2 of this utility model also mainly includes a top rod 10, an oil collection part 20, a locking part 30B, and a flow guiding part 40.

[0119] The top rod 10, oil collection part 20, and flow guiding part 40 of the portable sedimentation ground support device 1 of configuration 2 of this utility model are exactly the same as those of the portable sedimentation ground support device 1 of configuration 1, and will not be described again here. Hereinafter, only the specific structure of the locking part 30B, which is the difference, will be described in detail.

[0120] like Figure 5 As shown, similar to the locking part 30A of configuration 1, the locking part 30B of configuration 2 also includes a hook base 31B and a hook body 32B.

[0121] The hook base 31B is formed in a generally disc shape and is fixedly installed in the base portion 23 of the oil collection portion 2. On the upper surface of the hook base 31B, a plurality of main body mounting portions for inserting the hook body 32B are provided at equal intervals along the circumference.

[0122] The hook body 32B extends upward, with one end inserted and fixed to the mounting part of the body, and the other end forming a hook that bends outward in a radial direction.

[0123] Unlike the hook body 32A of configuration 1, the hook body 32B of configuration 2 extends upward while bending radially inward at the upper end of the limiting part 11 and then continuing to extend upward, thereby reducing the radial distance of the multiple hook bodies 32B to be suitable for insertion into the interior of the sedimentation connector FCD.

[0124] Furthermore, by bending the multiple hook bodies 32B toward the radially inward side at the upper end of the limiting portion 11, the limiting portion 11 of the push rod 10 can be fixed in the multiple hook bodies 32B, thereby preventing the push rod 10 from shifting in position relative to the oil collection portion 20 in the radial and axial directions.

[0125] Next, refer to Figure 6 and Figure 7 The suspension method of the portable sedimentation ground support device 1 of configuration 2 of this utility model will be described.

[0126] like Figure 6 As shown, in configuration 2 of this utility model, the sediment discharge connector FCD is connected to the liquid pipeline PT, etc. by a clamp, and mainly includes an integrally formed sediment discharge fixing part FCD1, sediment discharge guiding part FCD2, and sediment discharge hook part FCD3.

[0127] The aforementioned sediment removal fixing part FCD1 is configured as a flanged disc extending radially outward from the bottom end of the sediment removal connector FCD. The sediment removal fixing part FCD1 can be mounted on the metal plate on the surface of the fairing 4 by bolts or fasteners, so as to be fixed to the fuselage of the aircraft.

[0128] The aforementioned sedimentation guide FCD2 and sedimentation hook FCD3 are disposed inside the sedimentation connector FCD, and are generally formed into an inverted "L" shaped groove.

[0129] Similarly, the sedimentation guide FCD2 is used to guide the hook body 32B of the locking part 30B, and the sedimentation hook part FCD3 is used for the hook body 32B to hook.

[0130] like Figure 7As shown, after the locking part 30B of the portable desettling ground support device 1 of the present invention configuration 2 is suspended on the desettling connector FCD, the position of the oil inlet at the upper end of the opening 21 of the oil collection part 20 of the portable desettling ground support device 1 is higher than the position of the oil outlet at the lower end of the desettling connector FCD in the vertical direction, thereby preventing the fuel sediment from splashing during the desettling maintenance process.

[0131] <Procedures for Configuration 2>

[0132] The following describes the specific operating steps for performing sediment removal and maintenance on the auxiliary fuel tank 2 using the portable sediment removal ground support device 1 of configuration 2 of this utility model.

[0133] Step 1: Remove the plug at the sediment discharge port FK located on the outer surface of the fairing 4;

[0134] Step 2: Suspend and install the portable sediment release ground support device 1 of this utility model on the sediment release connector FCD. Specifically, align the hook body 32B of the locking part 30B with the sediment release guide part FCD2 of the sediment release connector FC and insert it upwards. After inserting it to the top, rotate the locking part 30B and suspend the hook body 32B on the sediment release hook part FC3 of the sediment release connector FC to ensure that the fuel deposits can flow out from the sediment release valve 3 through the portable sediment release ground support device 1 of this utility model.

[0135] Step 3: After all the fuel deposits in the auxiliary fuel tank 2 have flowed out, move the hook body 32A upward and rotate it so that it slides downward along the suspension guide XG2 so as to remove the suspension connector XG and the top rod 10.

[0136] Step 4: Reinstall the plug on the sediment discharge port FK to complete the sediment discharge operation.

[0137] As mentioned above, after completing step two, ground operators no longer need to hold the sedimentation ground support equipment (GSE) continuously, which significantly reduces workload, labor intensity, and work efficiency, thereby facilitating the smooth progress of sedimentation prevention maintenance operations.

[0138] Furthermore, compared to the portable sedimentation ground support equipment of Configuration 1, Configuration 2 integrates the suspension point with the connector by changing the structure of the sedimentation connector FCD, eliminating the need for an additional suspension connector XG. This simplifies installation, streamlines operation, and facilitates maintenance.

[0139] (Technical effect)

[0140] (1) With the portable sediment release ground support device 1 of this utility model, during the sediment release maintenance operation of the auxiliary fuel tank 2, the ground support device GSE can be suspended at the bottom of the auxiliary fuel tank 2 without the operator having to hold it all the time, which can significantly reduce the workload of the operator, reduce labor intensity, and thus improve work efficiency.

[0141] (2) The oil collection part 20 and the flow guiding part 40 of the portable sedimentation ground support device 1 of this utility model are made of transparent polymer material, which makes it easy for operators to observe during sedimentation maintenance, thereby effectively avoiding the occurrence of operational accidents.

[0142] (3) In the past, there were no similar products in China. Compared with similar products abroad, the new portable sedimentation ground support equipment 1 can retain the advantages of the previous version to the greatest extent, that is, the sedimentation pipeline and the installation form of the machine body remain unchanged, and the sedimentation valve can be used with the existing equipment without the need to develop a new sedimentation valve.

[0143] Although the structure and working principle of this utility model have been described above in conjunction with preferred embodiments, those skilled in the art should recognize that the above examples are merely illustrative and do not constitute a limitation on this utility model. Modifications and variations can be made to this utility model within the spirit and scope of the claims, and all such modifications and variations will fall within the protection scope of this utility model.
