Description

Technical Field

[0001] The invention relates to the technical field of locomotive hose handshakes, and in particular to a directional adjustable locomotive hose handshake and an abnormality processing method thereof. Background Art

[0002] The locomotive hose handshake is a device used to connect and fix functional hoses in the locomotive. The locomotive hose handshake can be used in the brake system to connect the brake hose, and can also be used in the air duct system to transmit the air source to each train.

[0003] In the prior art, the hose handshake is usually an integrally formed structure, the hose handshake is fixed to the mounting frame on the locomotive, and the hose is connected to the hose handshake. In actual use, when one end of the hose is screwed on the main air duct valve, the position of the other end of the hose is uncertain. At this time, the hose handshake needs to be set according to the position of the hose, and the position of the mounting frame on the locomotive must also be changed accordingly. Otherwise, the arrangement of the hose on the locomotive will be very messy and inconvenient to take care of. This means that every time the hose is disassembled and assembled, the position of the hose handshake and the mounting frame must be changed, and it is cumbersome to disassemble and assemble again. Summary of the invention

[0004] In order to ensure that the hose handshake and the mounting frame do not need to be adjusted each time the hose is connected to the hose handshake, so as to improve the installation efficiency of the hose, the present invention provides a directional adjustable locomotive hose handshake and an abnormality handling method thereof.

[0005] In the first aspect, the present invention provides a directional adjustable locomotive hose handshake, which adopts the following technical solution: An adjustable locomotive hose handshake comprises a handshake body, the handshake body comprises a fixing assembly connected to the locomotive and a connecting assembly ball-jointed to the fixing assembly and used for hose connection; the connecting assembly comprises a universal ball head; the fixing assembly comprises a fixing seat and a clamping sleeve, the fixing seat is provided with a rotating groove for the universal ball head to be inserted into and rotated circumferentially, the clamping sleeve is sleeved on the outside of the fixing seat and clamps the universal ball head to the rotating groove.

[0006] By adopting the above technical solution, the hose handshake is divided into a fixed component and a connecting component, and the two are connected in the form of a ball joint, so that the connecting component can be universally rotated on the fixed component. When the fixed component is installed on the mounting frame, since the connecting component can be universally rotated on the fixed component, the hose can be connected to the connecting component at any angle, without the need to disassemble and re-arrange the mounting frame and the fixed component, thereby improving the disassembly efficiency of the hose.

[0007] Optionally, the compression sleeve is telescopically provided with a locking pin, and the fixing seat is provided with a locking hole for the locking pin to be inserted to limit the rotation of the compression sleeve.

[0008] By adopting the above technical solution, when the locking pin is inserted into the locking hole, the clamping sleeve can be locked so as to be unable to rotate, so that the clamping sleeve is not easy to loosen after locking the universal ball head in the rotating groove.

[0009] Optionally, the connecting assembly includes a hose connector connected to one end of the hose and an intermediate connector connecting the hose connector to the fixing seat; the universal ball head is arranged on the intermediate connector; a rotation gap is formed between the compression sleeve, the universal ball head and the intermediate connector, and an elastic ring is arranged in the rotation gap to drive the universal ball head to always be vertically inserted into the rotation groove.

[0010] Optionally, the elastic ring includes a force-applying ring portion abutting against the clamping ring and an abutting ring portion connected to the force-applying ring portion and abutting against the intermediate connector.

[0011] By adopting the above technical solution, after the universal ball head is inserted into the rotating groove, due to the annular shape of the elastic ring, the elastic ring evenly applies circumferential force to the connecting component under the action of pressure on both sides, so that the universal ball head can always be inserted vertically into the rotating groove. Even if there is an angle deviation during insertion, it can be automatically corrected under the uniform force of the elastic ring to reset to the vertical insertion into the rotating groove, so that the hose can be installed on the hose handshake in a fixed posture, so that the hose arrangement is more beautiful and not easy to be messy.

[0012] Optionally, a connection between the force-applying ring portion and the abutting ring portion is bent toward a direction approaching the universal ball head.

[0013] By adopting the above technical solution, the connection between the force ring portion and the abutment ring portion is set to bend inwardly. Compared with bending outwardly, the elastic ring has an increased number of bends, which increases its elasticity, thereby ensuring that the elastic ring can drive the universal ball head to always be vertically inserted into the rotating groove.

[0014] Optionally, a limiting ring groove for the end of the force-applying ring portion to be inserted into is formed between the compression sleeve, the fixing seat and the universal ball head; and the end of the abutting ring portion abuts against the universal ball head.

[0015] By adopting the above technical solution, by inserting one end of the elastic ring into the limiting ring groove, the elastic ring is not easy to fall out, and the universal ball head can be better applied. In addition, the elastic ring can seal the rotating groove, so that impurities such as rainwater are not easy to enter from the gap between the universal ball head and the rotating groove.

[0016] In the second aspect, the present application provides a method for handling abnormal handshake of adjustable directional locomotive hose, which adopts the following technical solution: A method for handling abnormalities of a directional adjustable locomotive hose handshake is applied to a directional adjustable locomotive hose handshake, comprising: Get hose handshake image information; Determine the position of the fixed seat axis and the position of the ball head axis according to the hose handshake image information and the preset hose handshake feature; Determine the deflection angle according to the position of the fixed seat axis and the ball head axis; When the deflection angle is greater than a preset reference angle, an alarm is issued, a preset hook device is controlled to lift the hose, and image information of the elastic ring is obtained; Comparing the elastic ring image information with a preset reference elastic ring feature to determine whether the elastic ring is deformed; Based on the deformation of the elastic ring, a deformation prompt is issued and a preset elastic ring deformation processing method is used for processing; Based on the fact that the elastic ring has not been deformed, a reminder of the heavy object being suspended is issued and the heavy object is handled using the preset heavy object handling method.

[0017] By adopting the above technical solution, the system can perform image recognition on the position of the hose handshake, and determine whether there is an angular deviation between the axis position of the fixed seat and the axis position of the ball head in the hose handshake, so as to determine whether the elastic ring is faulty or whether there is foreign matter hanging on the hose, and then perform targeted processing for different abnormal situations, thereby ensuring that the hose handshake is always in a fully functional state.

[0018] Optionally, the elastic annular deformation processing method includes: Determine the position of the flattened deformation area on the elastic ring according to the image information of the elastic ring and the characteristics of the elastic ring; If and only if the position of the deformation region is not at the preset elastic ring top position, determining the rotation adjustment angle according to the deformation region position and the elastic ring top position; According to the rotation adjustment angle, the preset clamping device is controlled to rotate the elastic ring so that the deformation position area is located at the top position of the elastic ring; Determine the characteristic position of the connection gap at the connection between the force-applying ring portion and the abutting ring portion according to the image information of the elastic ring and the position of the deformation area; Controlling the preset expansion device to engage in the characteristic position of the connection gap, and expanding the connection between the force-applying ring portion and the abutting ring portion to a preset connection gap width value with a preset expansion force; A preset tightening ring is matched according to the width value of the connection gap, and the clamping device is controlled to tighten the tightening ring at a characteristic position of the connection gap to continuously and evenly expand the elastic ring in the circumferential direction.

[0019] By adopting the above technical solution, when the elastic ring has an abnormality, the system can first open the connecting gap at the deformed position, and then tighten the tightening ring in the connecting gap, so that the elastic ring can regain a certain elasticity, so that the hose handshake can continue to be used before the maintenance personnel perform maintenance.

[0020] Optional heavy object handling methods include: Acquire hose surface image information; Determine the foreign body features and foreign body feature locations based on the hose surface image information and a preset foreign body feature library; Determine the foreign object feature type according to the foreign object feature and the preset material library, the foreign object feature type includes a wet cloth and a plastic bag filled with rainwater; If the foreign body feature type is a plastic bag filled with rainwater, the bulge position on the plastic bag is determined based on the hose surface image information, the foreign body feature position and the foreign body feature; Controlling a preset jet device to jet at a preset puncturing power to puncture the bulge position on the plastic bag, and controlling the jet device to blow away the plastic bag at the characteristic position of the foreign body at a preset blowing power; If the characteristic type of the foreign body is a wet cloth, the jet device is controlled to spray the cloth at the characteristic position of the foreign body according to the blowing power, and whether there is a foreign body characteristic is determined according to the image information of the hose surface and the characteristic position of the foreign body; If there are foreign body features, determine the contour range of the foreign body features based on the hose surface image information and the foreign body features; The jet device is controlled according to the preset drying power to spray air to the characteristic contour range of the foreign body to dry the cloth piece, and the jet device is controlled by the blowing power to blow away the cloth piece at the characteristic position of the foreign body.

[0021] By adopting the above technical solution, the system can carry out targeted treatment on wet cloth pieces and plastic bags filled with rainwater. According to the characteristics of the two, both can be made lighter and then blown away by the jet device, which is relatively simple.

[0022] Optionally, the elastic ring cannot form a seal on the rotating groove after deformation, and mud and sand will enter the rotating groove. The rotating groove position needs to be processed. The rotating groove processing method includes: Get the ambient wind speed; According to the hose handshake image information, the entry position of the sediment generated between the universal ball and the rotating groove after the elastic ring is changed is determined; Determine the deployment angle of the guide plate on the wind direction guide device according to the entry position of the mud and sand and the wind direction guide device of the connection assembly preset in the hose handshake; Control the guide plate on the wind direction guide device to unfold according to the unfolding angle; Based on the ambient wind speed being greater than a preset reference wind speed, the guide plate is controlled to guide the ambient wind into the sediment entry position to blow out the sediment in the rotating trough; Based on the fact that the ambient wind speed is not greater than the reference wind speed, the jet device is controlled to jet the guide plate with a blowing power so as to control the guide plate to guide the wind blown by the jet device into the sediment entry position.

[0023] By adopting the above technical solution, by arranging a wind direction guiding device on the hose handshake, when a gap appears between the universal ball head and the rotating groove and mud and sand enters therein, the guide plate in the wind direction guiding device can guide the ambient wind or the wind blown by the jet device into the rotating groove, so that the rotating groove is always relatively clean. In the case of wind, the guide plate can always guide the ambient wind, thereby forming a wind wall to prevent mud and sand from entering the rotating groove.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: By adopting the above technical solution, the hose handshake is divided into a fixed component and a connecting component, and the two are connected in the form of a ball joint, so that the connecting component can be universally rotated on the fixed component. When the fixed component is installed on the mounting frame, since the connecting component can be universally rotated on the fixed component, the hose can be connected to the connecting component at any angle, without the need to disassemble and re-arrange the mounting frame and the fixed component, thereby improving the disassembly and assembly efficiency of the hose; When the universal ball head is inserted into the rotating groove, due to the annular shape of the elastic ring, the elastic ring evenly applies circumferential force to the connecting component under the action of pressure from both sides, so that the universal ball head can always be vertically inserted into the rotating groove. Even if there is an angle deviation during insertion, it can be automatically corrected under the uniform force of the elastic ring to reset to vertical insertion into the rotating groove, so that the hose can be installed on the hose handle in a fixed posture, so that the hose arrangement is more beautiful and not easy to be messy; By inserting one end of the elastic ring into the limiting ring groove, the elastic ring is not easy to come out, and the universal ball head can be better applied. In addition, the elastic ring can seal the rotating groove, so that impurities such as rainwater are not easy to enter from the gap between the universal ball head and the rotating groove.

[0027] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The embodiment of the present application discloses a directionally adjustable locomotive hose handshake.

[0029] Reference Figure 1 A directional adjustable locomotive hose handshake includes a handshake body 1, which is fixedly connected to a mounting frame fixed on the locomotive by bolts, and then the hose is connected to the handshake body 1, so as to fix the hose on the locomotive.

[0030] The handshake body 1 includes a fixing component 2 and a connecting component 3. The fixing component 2 is used to connect the mounting frame, and the connecting component 3 is used to connect the hose. The fixing component 2 and the connecting component 3 are connected by a ball joint structure, so that the connecting component 3 can be universally rotated on the fixing component 2 to facilitate the installation of the hose.

[0031] The connection assembly 3 includes a hose connector 31 and an intermediate connector 32. The hose connector 31 is threadedly connected to the end of the hose. The intermediate connector 32 is C-shaped and has a connection cavity 33 for the hose connector 31 to be inserted into. The intermediate connector 32 is rotatably provided with a clamping member 34, which penetrates into the connection cavity 33 and is threadedly connected to the hose connector 31. When connecting the hose, the hose connector 31 is first inserted into the connection cavity 33, and then the clamping member 34 is rotated so that the clamping member 34 is threadedly connected to the hose connector 31 to limit the hose connector 31 in the connection cavity 33.

[0032] The fixing assembly 2 includes a fixing seat 21 and a compression sleeve 22. The fixing seat 21 has a mounting slot 23 connected to the mounting frame on the locomotive on one side, and a rotation slot 24 is provided on the other side. The rotation slot 24 is a slot hole with a spherical inner cavity. The compression sleeve 22 is threadedly connected to the outer side of the fixing seat 21.

[0033] The intermediate connector 32 has a universal ball head 35 at one end away from the hose connector 31, and the universal ball head 35 can be inserted into the rotating groove 24 to achieve ball connection. In this embodiment, the opening diameter of the rotating groove 24 is slightly smaller than the diameter of the universal ball head 35. After the universal ball head 35 is inserted into the rotating groove 24, the universal ball head 35 is pressed into the rotating groove 24 by rotating the compression sleeve 22.

[0034] Reference Figure 1 and Figure 2 Furthermore, in order to prevent the compression sleeve 22 from loosening easily on the fixing seat 21, a locking hole 25 is provided on the fixing seat 21 on one side facing the compression sleeve 22, and a locking pin 26 is telescopically provided on the compression sleeve 22. The locking pin 26 is telescopically driven by a driving spring 27 so that the locking pin 26 always has a tendency to be inserted into the locking hole 25.

[0035] During the process of rotating the compression sleeve 22 , when the locking pin 26 is directly opposite to the locking hole 25 , the locking pin 26 can be inserted into the locking hole 25 under the driving of the driving spring 27 , thereby preventing the compression sleeve 22 from rotating.

[0036] Reference Figure 1 and Figure 3 Furthermore, a rotation gap 4 is formed between the compression sleeve 22, the universal ball head 35 and the intermediate connector 32. The rotation gap 4 is annular. An elastic ring 5 is arranged in the rotation gap 4. The elastic ring 5 is annular and includes a force-applying ring portion 51 and an abutting ring portion 52 connected to the force-applying ring portion 51.

[0037] When the elastic ring 5 is installed in the rotation gap 4, the force-applying ring portion 51 abuts against the compression sleeve 22, the abutting ring portion 52 abuts against the intermediate connector 32, and the connection between the force-applying ring portion 51 and the abutting ring portion 52 bends toward the direction close to the universal ball head 35. When the universal ball head 35 is inserted into the rotation groove 24, the compression ring can apply force through the force-applying ring portion 51, and evenly transmit the force to the intermediate connector 32 through the abutting ring portion 52, so that the universal ball head 35 can always be vertically inserted into the rotation groove 24, so that when the hose is fixed by the hose handshake, the hose can always be automatically arranged in a fixed direction position, which is more neat.

[0038] Furthermore, a limiting ring groove 6 is formed between the compression sleeve 22, the fixing seat 21 and the universal ball head 35, the end of the force ring portion 51 is inserted into the limiting ring groove 6, and the end of the abutting ring portion 52 abuts against one end of the universal ball head 35 close to the intermediate connector 32, so that the elastic ring 5 is not easy to pop out in the rotation gap 4. In addition, the elastic ring 5 can be used as a seal, which can seal the gap between the universal ball head 35 and the rotation groove 24.

[0039] Based on the same inventive concept, the embodiment of the present invention provides a method for handling abnormalities of a directional adjustable locomotive hose handshake. Various abnormalities may occur during the use of the hose handshake, such as the elastic ring 5 losing its elasticity, a heavy object hanging on the hose exerting pressure on the hose handshake, and mud and sand entering the rotating groove 24, etc. The system will perform targeted processing.

[0040] Reference Figure 4 , a method for handling abnormal handshake of adjustable directional locomotive hose comprises the following steps: Step S100: Acquire hose handshake image information.

[0041] The hose handshake image information refers to the image of the hose handshake obtained by the camera installed on the locomotive. The hose handshake is prone to abnormal problems. The system can monitor the hose handshake through the camera and perform image recognition analysis.

[0042] Step S101: determining the axis position of the fixing seat and the axis position of the ball head according to the hose handshake image information and the preset hose handshake feature.

[0043] The fixed seat axis position refers to the position of the axis of the rotating groove 24 in the fixed seat 21 in the hose handshake image information. The ball head axis position refers to the position of the axis of the universal ball head 35 in the hose handshake image information. By identifying and analyzing the hose handshake features in the hose handshake image information, the fixed seat axis position and the ball head axis position can be determined respectively.

[0044] Under normal circumstances, due to the provision of the elastic ring 5, the axis position of the fixed seat and the axis position of the ball head are coaxial. If an abnormality occurs, an angular deviation may occur between the axis position of the fixed seat and the axis position of the ball head.

[0045] Step S102: Determine the deflection angle according to the position of the axis of the fixing seat and the position of the axis of the ball head.

[0046] The deflection angle refers to the angle between the fixed seat axis position and the ball head axis position. After the fixed seat axis position and the ball head axis position are determined, the deflection angle can be obtained by analyzing the fixed seat axis position and the ball head axis position in the hose handshake image information.

[0047] Step S103: Based on the deflection angle being greater than a preset reference angle, an alarm is issued, a preset hook device is controlled to lift the hose, and image information of the elastic ring is obtained.

[0048] The reference angle is a reference angle value set by the technicians. It is used to measure whether the hose handshake is abnormal. It will not be described here. If the deflection angle is not greater than the reference angle, it means that there is no abnormality. If the deflection angle is greater than the reference angle, it means that the hose handshake may be abnormal.

[0049] The hook device is arranged on the locomotive for hoisting the hose.

[0050] When the image recognition finds that the deflection angle is greater than the reference angle, the system lifts the hose through the hook device so that the universal ball head 35 is temporarily reset to a position perpendicular to the rotation groove 24, and then the elastic ring 5 is checked.

[0051] The elastic ring image information is an image of the elastic ring 5 in a relaxed state obtained by a camera after the hook device lifts the hose. Normally, the elastic ring 5 can be reset to a relaxed state, in which the elastic ring 5 is not in a ring shape.

[0052] Step S104: Compare the elastic ring image information with the preset reference elastic ring features to determine whether the elastic ring 5 is deformed.

[0053] The reference elastic ring feature refers to the elastic ring 5 in an intact and relaxed state.

[0054] By comparing the elastic ring image information acquired by the camera with the reference elastic ring feature, it is possible to determine whether the elastic ring 5 is deformed. If the elastic ring 5 in the elastic ring image information is consistent with the reference elastic ring feature, it means that the elastic ring 5 is not deformed. If the elastic ring 5 in the elastic ring image information is inconsistent with the reference elastic ring feature, it means that the elastic ring 5 is deformed.

[0055] Step S1051: Based on the deformation of the elastic ring 5, a deformation prompt is issued and processed using a preset elastic ring deformation processing method.

[0056] If the elastic ring 5 is deformed abnormally, the system will issue a deformation prompt to remind the maintenance personnel. Before the maintenance personnel perform maintenance, the system will use an elastic ring deformation processing method to process it. The elastic ring deformation processing method is not described here in detail, but will be described in detail in the subsequent embodiments.

[0057] Step S1052: Based on the fact that the elastic ring 5 has not been deformed, a reminder of a heavy object being hung is issued, and the heavy object is processed using a preset heavy object processing method.

[0058] If the elastic ring 5 is not deformed, it may be that a heavy object is hung on the hose, which increases the weight of the hose, so that the universal ball head 35 cannot be vertically inserted into the rotation groove 24. In the case of a heavy object hanging on the hose, the system will use a heavy object handling method to handle it. The heavy object handling method is not described here in detail, and will be described in detail in the subsequent embodiments.

[0059] Reference Figure 5 The elastic annular deformation processing method comprises the following steps: Step S200: determining the position of the flattened deformation area on the elastic ring 5 according to the elastic ring image information and the elastic ring features.

[0060] When the hose sags, one side of the elastic ring 5 will be squeezed and deformed. The position of the deformation area refers to the deformation position on the elastic ring 5 that is flattened and cannot be reset. The position of the deformation area can be obtained by performing image recognition analysis on the elastic ring 5 in the elastic ring image information.

[0061] Step S201: When and only when the position of the deformation region is not at the preset elastic ring top position, determine the rotation adjustment angle according to the position of the deformation region and the elastic ring top position.

[0062] In this embodiment, maintenance of the deformed elastic ring 5 requires first rotating the position of the deformed region of the elastic ring 5 to the top position of the elastic ring 5 .

[0063] The rotation adjustment angle refers to the angle value required to rotate the deformation area to the top position of the elastic ring 5.

[0064] The top position of the elastic ring is a fixed position in the elastic ring 5. After the position of the deformation region is determined, the elastic ring 5 is analyzed based on the elastic ring image information to determine the angle between the position of the deformation region and the top position of the elastic ring.

[0065] Step S202: controlling the preset clamping device to rotate the elastic ring 5 according to the rotation adjustment angle so that the deformation position area is at the top position of the elastic ring.

[0066] The clamping device is arranged on the locomotive and is used for clamping the hose handshake.

[0067] After determining the rotation adjustment angle, the system controls the clamping device to clamp and rotate the elastic ring 5, so that the deformation area position of the elastic ring 5 is rotated to the top position to facilitate subsequent operations.

[0068] Step S203: determining a characteristic position of a connection gap at a connection point between the force-applying ring portion 51 and the abutting ring portion 52 according to the elastic ring image information and the position of the deformation region.

[0069] The elastic ring 5 has an inwardly recessed connection gap at the connection between the force-applying ring portion 51 and the abutting ring portion 52. When the elastic ring 5 is flattened, the width of the connection gap will be reduced accordingly. The connection gap characteristic position refers to the position of the connection gap in the area where the elastic ring 5 is deformed. By analyzing and identifying the position of the deformation area of ​​the elastic ring 5 in the elastic ring image information, the position of the connection gap in the deformation area can be determined.

[0070] Step S204: Control the preset expansion device to engage in the characteristic position of the connection gap to expand the connection between the force-applying ring portion 51 and the abutting ring portion 52 to a preset connection gap width value with a preset expansion force.

[0071] The expansion device is arranged on the locomotive, and has an arc block adapted to the connection gap. The arc block can be inserted into the connection gap and expand, so that the deformation area of ​​the elastic ring 5 is reset and expanded.

[0072] The opening force is the force set by the technician when the opening device opens the characteristic position of the connection gap of the elastic ring 5, which will not be described in detail here.

[0073] The connection gap width value is the normal width of the elastic ring 5 at the connection gap, which will not be described in detail here.

[0074] After determining the characteristic position of the connection gap, the system controls the expansion device to expand the characteristic position of the connection gap of the elastic ring 5, so that the characteristic position of the connection gap of the elastic ring 5 is restored to be consistent with the circumferential direction.

[0075] Step S205: matching a preset tightening ring according to the width value of the connection gap, and controlling the clamping device to tighten the tightening ring at the characteristic position of the connection gap to continuously and evenly expand the elastic ring 5 in the circumferential direction.

[0076] The system can restore the shape of the elastic ring 5 to the original state, and the elastic force of the elastic ring 5 may be restored or may not be restored. In this embodiment, a clamping ring is set in the connection gap of the elastic ring 5 to help the elastic ring 5 regain its elasticity. The clamping ring is clamped in the connection gap so that the elastic ring 5 cannot be flattened again, and the clamping ring has a certain elasticity, which can help the elastic ring 5 to apply force.

[0077] In view of the situation in which a heavy object is hung on the hose in step S1052, the heavy object needs to be processed. The heavy object processing method includes the following steps: Reference Figure 6 , step S300: obtaining hose surface image information.

[0078] The hose surface image information refers to an image of the hose surface acquired by a camera, and includes an image of the hose and an image of foreign matter that may exist on the hose.

[0079] Step S301: determining foreign matter features and foreign matter feature positions according to hose surface image information and a preset foreign matter feature library.

[0080] The foreign body feature library is a database obtained through machine learning that contains images of foreign bodies that may fall on the hose, which will not be described in detail here.

[0081] A foreign object feature is an object that hangs from the hose and causes the hose to increase in weight. A foreign object feature location is the location on the hose of the foreign object that hangs from the hose.

[0082] By comparing the hose surface image information with the foreign body feature library, the foreign body features can be matched in the hose surface image information. After the foreign body features are determined, the actual foreign body feature position on the hose can be determined based on the position of the foreign body features in the hose surface image information and the ratio of the image taken by the preset camera.

[0083] Step S302: determining the foreign object feature type according to the foreign object feature and a preset material library, wherein the foreign object feature type includes a wet cloth and a plastic bag filled with rainwater.

[0084] The foreign body feature type refers to the type of foreign body feature hanging on the hose. In this embodiment, the foreign body feature types include cloth and plastic bags. The cloth will adhere to the surface of the hose after being soaked by rainwater and will be heavy. The weight of the plastic bag will increase after the plastic bag is hung on the hose and rainwater enters it.

[0085] The material library is a database of materials including various foreign objects hanging on the hose obtained through machine learning, which will not be described in detail here.

[0086] By comparing the foreign body features in the hose surface image information with the material library, the type of foreign body features can be determined. For different types of foreign bodies, the system will use different methods to remove them.

[0087] Step S3031: If the foreign object feature type is a plastic bag filled with rainwater, the bulge position on the plastic bag is determined according to the hose surface image information, the foreign object feature position and the foreign object feature.

[0088] When a plastic bag is filled with rainwater, a bulge will appear, and the bulge contains rainwater. The bulge location refers to the location of the plastic bag filled with rainwater at the characteristic location of the foreign body.

[0089] The location of the bulge can be determined by identifying and analyzing the foreign body features in the hose surface image information.

[0090] Step S30311: Control the preset jet device to jet at the bulge position on the plastic bag with a preset puncturing power to puncture the bulge position, and control the jet device with a preset blowing power to blow away the plastic bag at the characteristic position of the foreign matter.

[0091] The jet device is arranged on the locomotive and can perform jetting. The force of the jetted airflow can be changed by changing the power of the jet device.

[0092] In this embodiment, for a plastic bag filled with rainwater, the system uses a jet device to blow the plastic bag apart so that the rainwater in the plastic bag can flow out. The plastic bag after the rainwater flows out is lighter and can be directly blown away by the jet device.

[0093] The puncture power is the power of the airflow that the jet device set by the technician can produce to blow the plastic bag, which will not be described in detail here. The blowing power is the power of the airflow that the jet device set by the technician can produce to blow away foreign matter, which will not be described in detail here.

[0094] After the bulge is located, the system controls the jet device to aim at the bulge and drives the jet with puncture power. At this time, the instantaneous airflow is large and can instantly puncture the plastic bag. When the rainwater flows away and the plastic bag becomes lighter, the system controls the jet device to blow away the plastic bag at the characteristic position of the foreign body with blowing power.

[0095] Step S3032: If the foreign body feature type is a wet cloth, the jet device is controlled to spray the cloth at the foreign body feature position according to the blowing power, and whether the foreign body feature exists is determined according to the hose surface image information and the foreign body feature position.

[0096] If the foreign object hanging on the hose is a wet piece of cloth, the system will first try to blow air at the cloth through the jet device to see if it can be blown away directly. After blowing, the system will check whether the cloth is still attached to the characteristic position of the foreign object through the image information of the hose surface and the characteristic position of the foreign object.

[0097] Step S30321: If there are foreign body features, determine the contour range of the foreign body features based on the hose surface image information and the foreign body features.

[0098] The foreign body characteristic contour range refers to the overall shape contour of the cloth hanging on the hose. The foreign body characteristic contour range can be determined by performing image recognition analysis on the foreign body characteristics in the hose surface image information.

[0099] Step S30322: Control the jet device to spray air to the characteristic contour range of the foreign body according to the preset drying power to dry the cloth piece, and control the jet device to blow away the cloth piece at the characteristic position of the foreign body with the blowing power.

[0100] The drying power is the power of the air flow generated by the jet device set by the technician to dry the wet cloth, which will not be described in detail here.

[0101] In this embodiment, for the cloth pieces that cannot be directly blown away by the jet, the system will first control the jet device to blow along the shape contour of the cloth pieces to dry the cloth pieces first. After the cloth pieces are dried, their weight becomes lighter, and then the cloth pieces are blown away by the jet device.

[0102] Reference Figure 7 After the elastic ring 5 is deformed, the hose sags, causing a gap between the universal ball head 35 and the rotating groove 24. At this time, the elastic ring 5 cannot form a seal for the rotating groove 24, and mud and sand will enter the rotating groove 24. The rotating groove position needs to be processed. The rotating groove processing method includes the following steps: Step S400: Obtaining ambient wind speed.

[0103] The ambient wind speed refers to the wind speed of the ambient wind at the hose handshake point. The locomotive is equipped with a sensor for measuring wind speed, and the ambient wind speed is obtained through the sensor.

[0104] Step S401: determining the entry position of the mud and sand generated between the universal ball and the rotating groove 24 after the elastic ring 5 is deformed according to the hose handshake image information.

[0105] The sand entry position refers to the gap position where sand can enter between the universal ball head 35 and the rotating groove 24 after the elastic ring 5 is deformed and the hose sags. By performing image recognition on the hose handshake image information, the sand entry position can be found from the hose handshake image information.

[0106] Step S402: Determine the deployment angle of the guide plate on the wind direction guiding device according to the mud and sand entry position and the wind direction guiding device of the connection assembly 3 preset in the hose handshake.

[0107] In this embodiment, a wind direction guide device is provided on the connecting assembly 3, and a guide plate capable of adjusting the angle is provided on the wind direction guide device, and the guide plate can guide the wind so that the wind is poured into the mud and sand entry position, thereby turning out the mud and sand in the rotating groove 24. The guide plate is annular and trumpet-shaped, and after the wind is blown into the guide plate, it can flow along the inner wall surface of the guide plate and be guided to the mud and sand entry position.

[0108] The deployment angle refers to the angle of the guide plate on the wind direction guide device. The surface of the guide plate needs to be directly opposite to the sediment entry position in order to guide the wind into the sediment entry position. Therefore, the deployment angle of the guide plate is related to the sediment entry position. In the hose handshake image information, the angle between the sediment entry position and the position of the wind direction guide device can be determined first, and then the deployment angle of the guide plate can be determined based on the angle.

[0109] Step S403: controlling the guide plate on the wind direction guiding device to unfold according to the unfolding angle.

[0110] After the deployment angle is determined, the system controls the guide plate to deploy.

[0111] In this embodiment, the system will first determine whether the ambient wind can be used to remove the silt in the rotating trough 24, and if not, the system will control the jet device to remove the silt.

[0112] Step S4041: Based on the ambient wind speed being greater than the preset reference wind speed, the guide plate is controlled to guide the ambient wind into the sediment entry position to blow out the sediment in the rotating trough 24 .

[0113] The reference wind speed is the environmental wind speed set by the technicians to remove the sediment in the rotating trough 24, which will not be described in detail here.

[0114] When the ambient wind speed is greater than the reference wind speed, the ambient wind at this time can be utilized. After the ambient wind blows into the guide plate, the ambient wind can enter the rotating groove 24 under the guidance of the guide plate to turn over the mud and sand inside.

[0115] Step S4042: Based on the fact that the ambient wind speed is not greater than the reference wind speed, the jet device is controlled to jet the guide plate with a blowing power to control the guide plate to guide the wind blown by the jet device into the sediment entry position.

[0116] If the ambient wind speed is not greater than the reference wind speed, the ambient wind speed is too small to turn out the mud and sand in the rotating trough 24. At this time, the system controls the jet device to align the guide plate position to spray, so that the air blown by the jet device is guided into the rotating trough 24 through the guide plate to turn out the mud and sand therein.
