Description

Technical Field

[0001] The invention relates to the technical field of pipeline cleaning, and in particular to a pipeline purging and cleaning device based on valve body detection. Background Art

[0002] The valve body is a major component of the valve. It is a shell containing an internal channel that is used to control the flow of fluids (such as gas, liquid, etc.) through pipelines or other closed systems. The valve body needs to be inspected regularly during use to ensure its normal operation and safety, such as cracks, corrosion and other problems on the surface. When inspecting, the outer surface of the valve body and the valve body pipeline needs to be purged and cleaned first to prevent inaccurate data during inspection.

[0003] At present, the patent with announcement number CN218049446U discloses a pipeline outer wall cleaning device, specifically a pipeline outer wall cleaning device, including a pipeline, a mounting frame, and a servo motor. The mounting frame is arranged at the front side of the pipeline, and the servo motor is fixedly mounted on the left surface of the mounting frame. A lead screw is fixedly sleeved on the output shaft of the servo motor, and a threaded sleeve is threadedly connected to the outer surface of the lead screw. A driving base is fixedly mounted on the back of the threaded sleeve, and a clamping arm is hingedly connected to the rear side of the upper surface of the driving base. The pipeline outer wall cleaning device can drive a U-shaped cleaning barrel to move through the driving base, so that the U-shaped cleaning barrel can clean the stubborn stains on the pipeline surface, and can effectively clean the pipeline outer wall, avoiding the loss of construction period and cost. At the same time, by clamping the U-shaped rolling barrel on the U-shaped cleaning barrel using a clamping column and a threaded limit block, it is convenient for users to disassemble and assemble.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] See also Figure 1-Figure 10The pipeline purging and cleaning device based on valve body detection comprises a placement box 1 located on one side of a gate valve 3, a fixing plate 11 is connected to the outside of the placement box 1, an operating panel 12 is clamped to the outside of the fixing plate 11, three placement chambers 25 are provided in the operating panel 12, a high-pressure water gun 15, a high-pressure air gun 16 and a coupling agent storage tank 17 are slidably connected in the placement chambers 25, and a trigger switch 36 for controlling the opening and closing of the high-pressure water gun 15 and the high-pressure air gun 16 is connected to the outer walls of the high-pressure water gun 15 and the high-pressure air gun 16. The tops of the water pressure gun 15 and the high-pressure air gun 16 are both connected to connecting pipes 18, one end of the two connecting pipes 18 passes through the fixed plate 11 and the other end is respectively connected to a high-pressure pump 32 and an air compressor 33, a water tank 34 is connected to the placement box 1, the high-pressure pump 32 is connected to the water tank 34, a piston rod 21 is slidably connected to the coupling agent storage tank 17, a sealing piston is fixedly connected to the bottom of the piston rod 21, a top plate 20 is fixedly connected to the top of the piston rod 21, and a uniform coating component is connected to the bottom of the coupling agent storage tank 17.

[0031] In the pipeline purging and cleaning device based on valve body detection of the present invention, when the staff needs to inspect the pipeline outside the gate valve 3, at this time, the operating panel 12 located on the fixed plate 11 can be taken out, and the operating panel 12 is respectively provided with a high-pressure water gun 15 and a high-pressure air gun 16. First, the high-pressure water gun 15 is slid down a certain distance in the placement cavity 25, so that the nozzle end of the high-pressure water gun 15 is exposed from the placement cavity 25 and extends a certain distance. During the sliding of the high-pressure water gun 15, the trigger switch 36 is pressed against the inner wall of the placement cavity 25, so that the trigger switch 36 starts the high-pressure water gun 15 to work; at this time, the staff can move the high-pressure water gun 15 by holding the operating panel 12, so that the high-pressure water gun 15 first purges and cleans the outer surface of the gate valve 3; cleaning liquid can be added to the water tank 34, so that the high-pressure water gun 15 can clean the oil and dust attached to the outer surface of the gate valve 3 and the pipeline more cleanly;

[0032] When the high-pressure water gun 15 has finished cleaning the gate valve 3, the high-pressure water gun 15 can be moved upward, so that the trigger switch 36 loses the squeezing force, and the high-pressure water gun 15 is turned off;

[0033] At the same time, the high-pressure air gun 16 is moved downward, so that the high-pressure air gun 16 slides down a certain distance in the placement cavity 25, so that the nozzle end of the high-pressure air gun 16 is exposed from the placement cavity 25 and extends a certain distance. During the sliding process of the high-pressure air gun 16, the trigger switch 36 is pressed against the inner wall of the placement cavity 25, so that the trigger switch 36 starts the high-pressure air gun 16 to work, and the high-pressure air gun 16 can blow dry the water stains on the outer surface of the gate valve 3 after cleaning;

[0034] After the high-pressure air gun 16 blows the outer surface of the gate valve 3 and the pipeline dry, the position to be detected is dry. At this time, the high-pressure air gun 16 can be turned off first. When closing, it is only necessary to raise the high-pressure air gun 16 to move it up in the placement cavity 25, so that the trigger switch 36 loses the squeezing force and no longer works, completing the closing.

[0035] After closing, the coupling agent storage tank 17 can be operated to slide down in the placement cavity 25, and the coupling agent storage tank 17 can be squeezed to squeeze out the coupling agent inside. As the operating panel 12 moves, the coupling agent is coated on the surface to be tested. After the coating is completed, the operating panel 12 can be restored to its original position, and the worker can perform the ultrasonic detection end fitting test on the position that has been purged and cleaned.

[0036] By sequentially arranging the high-pressure water gun 15, the high-pressure air gun 16 and the coupling agent storage tank 17 in the three placement cavities 25 in the operating panel 12, the worker can hold the operating panel 12 and press it to start the high-pressure water gun 15 and the high-pressure air gun 16 in turn. As the operating panel 12 moves, the gate valve 3 and the outside of the pipeline can be flushed with water containing cleaning liquid, the cleaned position can be blown dry with the gas sprayed from the high-pressure air gun 16, and the coupling agent can be sprayed from the coupling agent storage tank 17 to coat the purged and cleaned position. This arrangement can not only cope with the purging and cleaning of the irregular outer surfaces of the gate valve 3 and the outer side of the pipeline, but also effectively ensure the thorough cleaning of the outer surface stained with oil, and at the same time, the gas can be used to blow dry the position to be tested, and the coupling agent required for detection can be smoothly coated, thereby ensuring a good cleaning effect while simplifying the cleaning operation and the detection operation.

[0037] By utilizing the arrangement of the placement cavity 25, the high-pressure water gun 15 and the high-pressure air gun 16 can be taken out from the operating panel 12 separately and used separately, thereby further improving the flexibility of the cleaning device.

[0038] In the above structure, the high-pressure water gun 15 sprays water through the connection between the high-pressure pump 32 and the water tank 34, and the high-pressure air gun 16 sprays air through the air compressor 33, and the water spraying or air spraying operation is started by pressing the trigger switch 36. These are all existing mature technologies, so they will not be described in detail here.

[0039] When the coupling agent needs to be squeezed out, the worker can press the top plate 20 to drive the piston rod 21 at the lower end of the top plate 20 to slide down in the coupling agent storage tank 17, thereby causing the sealing piston to squeeze the coupling agent and squeeze it out. In this way, the coupling agent can be squeezed out through a simple push-pull action;

[0040] Meanwhile, when the coupling agent needs to be filled, the piston rod 21 can be directly pulled to drive the sealing piston to be separated from the coupling agent storage tank 17, and the coupling agent can be filled.

[0041] As a preferred technical solution of the present invention, the uniform coating component includes a brush plate 19 and a guide block 22. An enlarged cavity 37 is provided at the top of the operating panel 12, and a square cavity 38 is provided at the bottom. Both the enlarged cavity 37 and the square cavity 38 are connected to the placement cavity 25 located on the outside of the coupling agent storage tank 17. The outer wall of the coupling agent storage tank 17 is fixedly connected with a tank retaining ring 31, and the tank retaining ring 31 is slidably connected in the enlarged cavity 37. The square cavity 38 is connected with a brush plate 19, and a plurality of bristles are fixedly connected to the bottom of the brush plate 19. The bottom of the discharge port of the coupling agent storage tank 17 is connected with a guide block 22, and an inclined guide groove 39 is provided in the guide block 22. A falling groove 40 connected to the inclined guide groove 39 is provided in the brush plate 19. The bottom of the guide block 22 is fixedly connected to the brush plate 19, and a connecting ring 23 is fixedly connected to the outside of the top. The connecting ring 23 is threadedly connected to the outer wall of the coupling agent storage tank 17.

[0042] Specifically, when the coupling agent storage tank 17 slides in the placement cavity 25, the tank retaining ring 31 will slide in the enlarged cavity 37 until the bottom surface of the tank retaining ring 31 fits with the top surface of the enlarged cavity 37, at which time the brush plate 19 slides out of the square cavity 38, and the coupling agent can be applied smoothly;

[0043] After being extruded, the coupling agent will flow along the inclined guide groove 39 in the guide block 22 to the drop groove 40 in the brush plate 19, so that the coupling agent can fully infiltrate the bristles through the drop groove 40. As the operating panel 12 moves, the bristles and the position to be detected can be fully coated with the coupling agent.

[0044] Through the brush plate 19 and the bristles, the coupling agent can be applied more fully, thereby improving the convenience of applying the coupling agent; through the guide block 22 and the inclined guide groove 39, the coupling agent can be fully guided into the bristles at the bottom of the brush plate 19.

[0045] When people need to use the coupling agent alone, they can first slide the coupling agent storage tank 17 down so that the tank retaining ring 31 slides in the enlarged cavity 37 and the bottom surface of the tank retaining ring 31 abuts against the top surface of the enlarged cavity 37. At this time, rotate the connecting ring 23 to separate the connecting ring 23 from the bottom outer side of the coupling agent storage tank 17, so that the guide block 22 can be separated from the coupling agent storage tank 17. At this time, pull the coupling agent storage tank 17 to slide out of the enlarged cavity 37. Finally, thread the guide block 22 and the coupling agent storage tank 17 together, and the coupling agent can be used alone. This arrangement can improve the flexible use of the coupling agent.

[0046] As a preferred technical solution of the present invention, the bottom of the operating panel 12 is rotatably connected to a bottom plate 29 , and the bottom plate 29 is located at the bottom of the square cavity 38 .

[0047] Specifically, when people no longer use the purging and cleaning device and the coupling agent and need to put the operating panel 12 back into the fixed panel 11, they first lift up the coupling agent storage tank 17 so that the coupling agent storage tank 17 drives the brush plate 19 to slide back into the square cavity 38. At this time, the bottom plate 29 can be rotated so that the bottom plate 29 covers the bottom of the square cavity 38 so that the bristles no longer protrude, and the coupling agent storage tank 17 does not continue to slide in the placement cavity 25. This arrangement not only ensures that the coupling agent storage tank 17 no longer slides, but also closes the bristles in the square cavity 38 to prevent excessive dust adhesion. At the same time, it also ensures that when the high-pressure water gun 15 and the high-pressure air gun 16 are in use, the brush plate 19 is located in the square cavity 38 and does not actively move down.

[0048] For the used bristles, the high-pressure water gun 15 or the high-pressure air gun 16 can be taken out from the placement cavity 25, and the bristles stained with the coupling agent can be sprayed to ensure the cleanliness of the bristles.

[0049] The bottom plate 29 here should be embedded in the square cavity 38 and rotated, that is, ensure that the bottom of the bottom plate 29 is flush with the bottom surface of the operating panel 12.

[0050] As a preferred technical solution of the present invention, a gun blocking ring 30 is fixedly connected to the outer sides of the tops of the high-pressure water gun 15 and the high-pressure air gun 16 .

[0051] Specifically, when the high-pressure water gun 15 and the high-pressure air gun 16 are sliding, in order to prevent the two from directly sliding out of the placement cavity 25, a gun blocking ring 30 can be used to prevent the two from falling off.

[0052] This arrangement ensures that the high-pressure water gun 15 and the high-pressure air gun 16 do not slide down and separate from the placement cavity 25, while ensuring that both can slide up and separate from the placement cavity 25.

[0053] As a preferred technical solution of the present invention, a groove 26 and a card slot 27 are opened on the outer wall of the fixed plate 11, the groove 26 and the card slot 27 are connected, the operating panel 12 is located in the card slot 27 and is card-engaged therewith, and the outer walls of the operating panel 12 are fixedly connected with straps 13 on both sides, the two straps 13 are symmetrically arranged, and the bottom surface of the straps 13 is card-engaged with the groove 26.

[0054] Specifically, when taking out the operating panel 12, the operating panel 12 can be slid out of the card slot 27. After use, the operating panel 12 can be placed in the card slot 27. During the placement process, the two straps 13 will fit with the cutouts 26 to ensure that the operating panel 12 is easy to take out.

[0055] As a preferred technical solution of the present invention, a rotating groove 28 is opened at the top of the fixed plate 11, and a rotating shaft 24 is fixedly connected in the rotating groove 28. A protective cover 2 is rotatably sleeved on the outer side of the rotating shaft 24. The protective cover 2 is located on the outer side of the fixed plate 11 and the operating panel 12. An anti-collision pad 9 is fixedly connected to the inner wall side of the protective cover 2 close to the operating panel 12, and buckle grooves 10 are opened on the protective cover 2 and the anti-collision pad 9.

[0056] Specifically, when the operation panel 12 needs to be taken out, the protective cover 2 can be rotated through the buckle slot 10 so that the top of the protective cover 2 rotates outside the rotating shaft 24, and the protective cover 2 can be rotated to 180 degrees, so that one side of the protective cover 2 fits with the top surface of the placement box 1, ensuring that the protective cover 2 is temporarily stable;

[0057] When the operation panel 12 is finished being used, the protective cover 2 can be rotated to restore it so that it protects the operation panel 12. During the rotation and restoration, the anti-collision pad layer 9 will contact the outer wall of the operation panel 12, thereby reducing noise and buffering the protective cover 2 at the same time.

[0058] As a preferred technical solution of the present invention, the fixing plate 11 and one side of the outer wall of the placement box 1 are hinged, and a locking piece is fixedly installed on the fixing plate 11 and the placement box 1 away from the hinge, and a water filling cover 35 is connected to the top of the water tank 34.

[0059] Specifically, when water needs to be added to the water tank 34 , the fixing plate 11 can be rotated to open the fixing plate 11 and the outer locking piece of the placement box 1 to expose the water tank 34 , and then the water adding cover 35 is used to add water to it.

[0060] When the high-pressure pump 32 and the air compressor 33 need to be installed and repaired, the fixing plate 11 can also be rotated to open them for operation.

[0061] By arranging the fixing plate 11 to be hinged to the storage box 1 , the interior of the storage box 1 can be operated.

[0062] As a preferred technical solution of the present invention, the outside of the placement box 1 is fixedly connected with a U-shaped angle steel 4, the outer wall of the gate valve 3 is fixedly connected with an L-shaped angle steel 5, the L-shaped angle steel 5 and the U-shaped angle steel 4 are fixedly connected by fastening bolts 6, and the bottom of the placement box 1 is fixedly connected with two symmetrically arranged support frames 7, and the bottom of the support frame 7 is fixedly connected with a fixing ring 8, which abuts against the outside of the pipeline.

[0063] Specifically, the placement box 1 can be connected to the gate valve 3 by using the fastening bolts 6 between the L-shaped angle steel 5 and the U-shaped angle steel 4, and the placement box 1 can be supported by using the support frame 7 and the fixing ring 8.

[0064] It should be noted that the fixed ring 8 here can also be replaced by a hoop structure and be firmly installed on the outer side of the pipeline, aiming to ensure the stability of the placement box 1.

[0065] As a preferred technical solution of the present invention, a plurality of hand-holding grooves 14 are formed on both sides of the outer wall of the operation board 12, and the two groups of hand-holding grooves 14 are symmetrically arranged.

[0066] Specifically, when the staff takes the operation board 12, they can hold the hand-holding groove 14, which ensures the stable holding of the operation board 12.

[0067] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
