Description

Technical Field

[0001] The utility model relates to the technical field of road pollution removal vehicles, in particular to a suction pipeline switching opening and closing mechanism. Background Art

[0002] Road pollution removal vehicles with washing and sweeping functions often need to use gate valve structures to switch pipelines during function switching.

[0003] However, the valve body used in the pipeline of the current road pollution removal vehicle is a traditional single-cylinder gate valve structure. As shown in Technical Solution 202320196442.2, the single-cylinder gate valve applies unilateral force to the gate valve body, which may cause jamming. During the sewage suction process, the jamming resistance caused by the unilateral force application will often be superimposed on the resistance caused by the dirt blocking the gate valve, resulting in the gate valve being blocked, which leads to a particularly high failure rate of the gate valve structure, and often requires manual maintenance and repair. Utility Model Content

[0004] To this end, it is necessary to provide a suction pipeline switching opening and closing mechanism to solve the problem that the sticking resistance caused by the unilateral force applied in the prior art is often superimposed with the resistance caused by the dirt blocking in the gate valve, resulting in gate valve blockage, which leads to a particularly high failure rate of the gate valve structure and frequent need for manual maintenance and repair.

[0005] To achieve the above-mentioned purpose, the inventor provides a suction pipeline switching opening and closing mechanism, including a gate valve base, a gate valve driving member, a gate valve body and a gate valve cleaning assembly;

[0006] The gate valve base is provided with a material passage opening and a gate valve activity area, the setting spaces of the material passage opening and the gate valve activity area are arranged alternately, and the two ends of the gate valve activity area pass through the outer side of the gate valve base;

[0007] The gate valve driving member is provided with a movable end;

[0008] The gate valve body is inserted into one end of the gate valve active area and is movably connected to the active end of the gate valve driving member;

[0009] The gate valve cleaning assembly is arranged between the gate valve active area and the non-insertion end of the gate valve body, and includes a sealing cover and a sealing cover fixing member. The sealing cover is hinged to the non-insertion section of the gate valve body. The sealing cover fixing member is arranged on the gate valve base and is used to apply a force to the cover surface of the sealing cover to fix it to the non-insertion section of the gate valve body.

[0010] Different from the prior art, the above technical solution has the following advantages: by setting a gate valve active area staggered with the material passing space of the material passing port on the gate valve base, the gate valve active area is reserved with two ends connected to the outside of the gate valve base, and during the movement of the gate valve body in the gate valve active area, the end of the gate valve body can push the dirt to the non-insertion section of the gate valve body and discharge it from the connection point, and the sealing cover of the gate valve cleaning assembly cooperates with the sealing cover fixing part to seal the opening of the non-insertion section in the non-cleaning state to ensure the sealing. In the process of the gate valve structure working, the dirt can be discharged from the gate valve active area in time, avoiding the problem of abnormal opening and closing of the gate valve body caused by dirt blockage.

[0011] As a preferred embodiment of the present application, there are two gate valve driving members, which are arranged on both sides of the gate valve base. By arranging the gate valve driving members on both sides of the gate valve base, multi-directional external forces are applied to the gate valve body, and the driving force received by the gate valve body is in the same direction as the movement direction in the gate valve activity area, avoiding the problem of movement direction deviation caused by unilateral force.

[0014] As a preferred embodiment of the present application, the sealing cover fixing member is a magnet, and one end of the magnet faces the sealing direction of the sealing cover. By using the magnet, the sealing cover of the metal structure can be locked and sealed.

[0015] As a preferred embodiment of the present application, the sealing cover fixing member is a torsion spring, which is sleeved at the hinge between the sealing cover and the gate valve body and is used to apply elastic force to the sealing cover toward the non-insertion section. By providing a torsion spring, an elastic force is applied to the sealing cover, so that the sealing cover can be pressed against the non-insertion end, and the elastic force can be overcome to make way during the waste discharge process.

[0016] As a preferred embodiment of the present application, the gate valve base is tilted in the height direction. By tilting the gate valve base in the height direction, the sealing cover can be close to the sealing cover fixing member by gravity and fixed by the sealing cover fixing member.

[0017] As a preferred embodiment of the present application, an extension area is provided on the top of the gate valve body, and the extension area is connected to the gate valve drive. By providing the extension area of ​​the gate valve body, it is convenient to rely on the extension area to connect with the gate valve drive, reduce the difficulty of setting the position of the gate valve drive and improve the convenience of connecting the gate valve body and the gate valve drive.

[0043] Please also read Figures 1 to 5This embodiment discloses a suction pipeline switching opening and closing mechanism, including a gate valve base 10, a gate valve driving member 20, a gate valve body 30 and a gate valve cleaning assembly 40. The gate valve base 10 is provided with a material passage 11 and a gate valve activity area 12, and the setting spaces of the material passage 11 and the gate valve activity area 12 are arranged alternately, that is, the material conduction direction of the material passage 11 and the opening and closing direction of the gate valve body 30 in the gate valve activity area 12 are arranged alternately. The gate valve body 30 is able to block or conduct the material transportation at the position of the material passage 11. The flow port is connected to the conveying pipeline of the road pollution removal vehicle, and the two ends of the gate valve activity area 12 pass through the outside of the gate valve base 10. The gate valve driving member 20 is arranged on the gate valve base 10 or the vehicle, and the gate valve driving member 20 is provided with a movable end. The gate valve body 30 is inserted and arranged from the gate valve activity area 12 toward one end of the gate valve base 10, and is movably connected with the movable end of the gate valve driving member 20. The gate valve cleaning assembly 40 is arranged between the gate valve active area 12 and the non-insertion end 13 of the gate valve body 30, and includes a sealing cover 41 and a sealing cover fixing part 42. The sealing cover 41 is hinged to the non-insertion section of the gate valve body 30, and the sealing cover fixing part 42 is arranged on the gate valve base 10, and is used to apply a force to the cover surface of the sealing cover 41 to fix it to the non-insertion section of the gate valve body 30.

[0044] According to the above structure, in the actual use of the suction pipeline switching opening and closing mechanism, when the material port 11 needs to be opened, the active end of the gate valve driving member 20 drives the gate valve body 30 to move, and the gate valve body 30 leaves the gate valve active area 12 where the material port 11 is located. Then the material can be transferred and transported through the pipeline and the material port 11 of the gate valve base 10. When it is necessary to block the flow of materials, the active end of the gate valve driving member 20 drives the gate valve body 30 to move in the opposite direction, and the gate valve body 30 blocks the gate valve active area 12 where the material port 11 is located again, blocking the flow of materials in the pipeline and the gate valve body 30. When dirt accumulates in the gate valve active area 12 during the material passing process, the gate valve body 30 pushes the dirt toward the non-insertion end 13 of the gate valve active area 12 during the movement process. After the sealing cover 41 contacts the external force transmitted by the dirt, it detaches from the sealing cover fixing part 42 and opens, and the dirt is discharged from the gate valve base 10 where the gate valve active area 12 of the gate valve faces the non-insertion end 13 and the outside world, completing the discharge process. After the discharge process is completed, the sealing cover 41 is reset by the external force applied by the sealing cover fixing part 42, blocking the gate valve base 10 where the gate valve active area 12 of the gate valve faces the non-insertion end 13 and the outside world, completing the sealing process. By setting a gate valve active area 12 staggered with the material passing space of the material passing port 11 on the gate valve base 10, the gate valve active area 12 is reserved with two ends connected to the outside of the gate valve base 10. When the gate valve body 30 is located in the gate valve active area 12 and moves, the end of the gate valve body 30 can push the dirt to the non-insertion section of the gate valve body 30 and discharge it from the connection point. The sealing cover 41 of the gate valve cleaning assembly 40 cooperates with the sealing cover fixing part 42 to seal the opening of the non-insertion section in the non-cleaning state to ensure the sealing. In the process of the gate valve structure working, the dirt can be discharged from the gate valve active area 12 in time, avoiding the problem of abnormal opening and closing of the gate valve body 30 caused by dirt blockage.

[0045] As a preferred embodiment of the present application, there are two gate valve driving members 20, which are arranged on both sides of the gate valve base 10. By arranging the gate valve driving members 20 on both sides of the gate valve base 10, a multi-directional external force is applied to the gate valve body 30, and the driving force received by the gate valve body 30 is in the same direction as the movement direction in the gate valve active area 12, thereby avoiding the problem of movement direction deviation caused by unilateral force.

[0046] As a preferred embodiment of the present application, the gate valve driving member 20 is a hydraulic rod, and the telescopic portion of the hydraulic rod is the movable end 21 .

[0047] As a preferred embodiment of the present application, both ends of the gate valve active area 12 penetrate the outside of the base in the height direction. By penetrating both ends of the gate valve active area 12 through the outside of the base in the height direction, it is convenient to discharge waste in the height direction.

[0048] As a preferred embodiment of the present application, the sealing cover fixing member 42 is a magnet, and one end of the magnet faces the sealing direction of the sealing cover 41. By using the magnet, the sealing cover 41 of the metal structure is conveniently locked and sealed.

[0049] As a preferred embodiment of the present application, the sealing cover fixing member 42 is a torsion spring, which is sleeved at the hinge between the sealing cover 41 and the gate valve body 30, and is used to apply an elastic force toward the non-insertion section to the sealing cover 41. By providing a torsion spring, an elastic force is applied to the sealing cover 41, so that the sealing cover 41 can be pressed against the non-insertion end 13, and the elastic force can be overcome to make way during the waste discharge process.

[0050] As a preferred embodiment of the present application, the gate valve base is tilted in the height direction. By tilting the gate valve base in the height direction, the sealing cover 41 is convenient to approach the sealing cover fixing member 42 by gravity and be fixed by the sealing cover fixing member 42.

[0051] As a preferred embodiment of the present application, an extension area 31 is provided on the top of the gate valve body 30, and the extension area 31 is connected to the gate valve drive 20. By providing the extension area 31 of the gate valve body 30, it is convenient to rely on the extension area 31 to connect with the gate valve drive 20, reduce the difficulty of position setting of the gate valve drive 20, and improve the convenience of connecting the gate valve body 30 with the gate valve drive 20.

[0052] As a preferred embodiment of the present application, the gate valve active area 12 is a through groove structure. By setting the gate valve active area 12 as a through groove structure, the structure of the gate valve active area 12 is simplified and the structural stability of the gate valve base 10 is provided.
