[0002] Metal pipelines have low investment, flexible layout, small footprint, convenient on-site production and installation of straight pipe sections and pipe fittings, mature construction technology, short construction period and low operating costs. The corrosion of steel pipelines in soil is mainly electrochemical corrosion. Due to the influence of various factors in the soil, macroscopic and microscopic anode areas and cathode areas are formed on the surface of the pipeline, thus forming a corrosion cell. The use of cathodic protection technology can effectively inhibit the corrosion of steel pipes in soil. This method is to connect a metal with a more negative potential (zinc plate) to the protected metal pipeline and place them in the same electrolyte, so that the electrons on the metal are transferred to the protected metal, so that the entire protected metal is under a negative potential.

[0038] like Figure 1-9 As shown, the present invention is a surface pretreatment device, which is applied to a zinc alloy sacrificial anode, comprising a working tank 1 with an open side, a placing table 2 for placing a block of zinc alloy is provided on the working tank 1, a grinding component 3 for grinding the block of zinc alloy is also provided on the working tank 1, and further comprising:

[0039] The clamping mechanism 4 includes two symmetrical side clamping plates 41 arranged on the placing table 2, and guide rods 42 respectively arranged on the end surfaces of the two side clamping plates 41 that are separated from each other, and is used to clamp and position the placed block of zinc alloy on both sides;

[0040] A feeding mechanism 5 is flipped and arranged at the opening, and is used to deliver the block zinc alloy to the placement table 2;

[0041] The adjusting mechanism 6 is rotatably arranged on the working groove 1 and on the other side of the feeding mechanism 5, and is used for adjusting the height of the grinding component 3 so that the grinding surface of the grinding component 3 is placed on the working surface of the block zinc alloy.

[0042] In a specific implementation, the feeding mechanism 5 can flip the block zinc alloy with pre-treatment on the working surface and transport it to the placement groove left by the center turning process on the placement table 2 for welding in the inner groove of the working groove 1. There is no need for manual feeding, the feeding is simple and convenient, and there is no need to directly contact the block zinc alloy that has just been polished, so as to avoid the grinding debris from stabbing the staff. In addition, the adjustment mechanism 6 is used to control the grinding component 3 to descend to the upper working surface of the block zinc alloy, so that the grinding surface on the grinding component 3 is in contact, thereby conveniently completing the grinding and decontamination operation of the upper working surface of the block zinc alloy, so as to grind off dirt such as oxide scale, and no coating or oil stain is allowed to exist;

[0043] Furthermore, the clamping mechanism 4 includes two symmetrical side clamping plates 41 in the central placement groove of the placement table 2 and a guide rod 42 welded to the midpoint of the outer end of the side clamping plate 41, which can centrally clamp the block of zinc alloy placed in the central placement groove.

[0044] It should be noted that the grinding component 3 in the present device uses a grinding steel brush in conjunction with the reciprocating movement of a horizontal guide rail table to grind the working surface on the block zinc alloy to be pretreated.

[0045] In one embodiment, the feeding mechanism 5 includes a bracket 51 rotatably arranged in the opening, two support rods 52 symmetrically slidably arranged in the bracket 51, and a number of vacuum suction cups 53 for adsorbing and fixing the block zinc alloy are evenly arranged on the support rods 52. A bidirectional screw 54 is transversely rotatably arranged at the ends of the two support rods 52 near the bracket 51, and a worm gear 55 is arranged on the bidirectional screw 54. In this design, by using the two support rods 52 driven by the bidirectional screw 54 to slide on the inner groove wall of the bracket 51 in the bracket 51 that is rotatably connected in the opening turned on one side of the working groove 1, and the number of vacuum suction cups 53 evenly installed on the support rods 52, the block zinc alloy to be surface pretreated can be supported by controlling the number of vacuum suction cups 53 installed on the two support rods 52 with adjustable spacing, thereby improving the stability of the flip transfer and better meeting the actual production and processing needs.

[0046] It should be noted that a fixed worm wheel 55 is sleeved on the middle end of the bidirectional lead screw 54, which can be used in conjunction with the worm 65 in the device to transmit the force.

[0047] In one embodiment, the adjustment mechanism 6 includes a vertical slide groove 61 rotatably arranged on the other side of the working groove 1, and an L-shaped frame 62 slidably arranged in the inner groove of the vertical slide groove 61. Telescopic rods 63 for telescopically adjusting the connection with the grinding component 3 are arranged on both sides of the horizontal plate part of the L-shaped frame 62 parallel to the grinding component 3. A motor-driven screw 64 is arranged on the side of the telescopic rod 63 and on the L-shaped frame 62. The bottom end of the screw rod 64 is fixed with a worm 65 meshing with the worm gear 55. Such a design uses a vertical slide 61 that is rotatably connected to the other side of the relatively open working groove 1, and an L-shaped frame 62 that is slidably connected to the inner groove of the vertical slide 61, and the cross plate part of the L-shaped frame 62 is fixedly connected to the grinding component 3 with bolts using a telescopic rod 63. When the motor-driven screw 64 installed on the L-shaped frame 62 rotates, the horizontal height of the grinding component 3 is adjusted under the telescopic limit of the telescopic rods 63 on both sides until the grinding steel brush of the grinding component 3 contacts the working surface of the block zinc alloy, and the guide rail platform power equipment included in the grinding component 3 is started to drive the grinding steel brush to move in a straight line from the open side of the working groove 1. At this time, during the grinding operation, the grinding debris will be synchronously driven to concentrate to the other side.

[0048] It should be noted that the worm 65 welded at the bottom end of the screw rod 64 is meshingly transmitted with the worm wheel 55. When the integrated structure of the screw rod 64 and the worm 65 welded together rotates under the action of the corresponding motor, the meshing transmission of the worm 65 and the worm wheel 55 will drive the two-way screw rod 54 fixedly mounted on the center of the upper end surface of the worm wheel 55 to rotate, and then drive the two support rods 52 that are separated from the block zinc alloy and rotated on the thread on the two-way screw rod 54 to move away from each other on the inner groove wall of the bracket 51, so that the grinding steel brush on the descending grinding component 3 performs a grinding operation on the working surface of the block zinc alloy.

[0049] Preferably, the upper plate portion of the L-shaped frame 62 is provided with an operating handle 621 that is vertically slidably connected to the inner side of the vertical slide 61. This design provides convenience in operation by welding the operating handle 621 on the upper plate portion of the L-shaped frame 62, and facilitates vertical lifting and lowering adjustment in the inner groove of the vertical slide 61.

[0050] In one embodiment, a collection assembly 66 for centrally sucking grinding debris is provided on the inner side of the upper vertical plate portion of the L-shaped frame 62;

[0051] The material collecting assembly 66 includes a box body 661 arranged on the inner side of the upper vertical plate portion of the L-shaped frame 62, a piston plate 662 arranged in the piston cavity on the rear side of the box body 661, a piston rod 663 is arranged on the piston plate 662, which passes through the top of the box body 661 and is fixed to the inner side of the upper vertical plate of the L-shaped frame 62, a material collecting box 664 for gathering and collecting grinding debris is vertically assembled on the front side of the box body 661, a dust filter 665 is arranged on the material collecting box 664 and is connected to the lower side of the piston cavity separated by the piston plate 662, a material guiding ramp 666 which is lower on the outside and higher on the inside is arranged on the inner bottom surface of the material collecting box 664, and a material collecting port 667 which is connected to the feed ramp of the material guiding ramp 666 is arranged on the outside of the box body 661. With such a design, the block of zinc alloy that has been pre-treated by grinding is transferred outwardly through the box body 661 installed on the inner side of the upper plate of the L-shaped frame 62 and the piston plate 662 adjusted up and down in the piston cavity at the rear side of the box body 661. When the L-shaped frame 62 is driven to rise and fall in the inner groove of the vertical slide 61 by the operating handle 621, the piston plate 662 is driven to move upward in the closed piston cavity by the piston rod 663 welded on the upper plate of the L-shaped frame 62, so that the lower cavity separated by the piston plate 662 in the piston cavity is enlarged, thereby generating a negative pressure effect, so that the grinding debris concentrated on this side enters through the collection port 667 turned on the lower side of the outer side of the box body 661 and is collected in a concentrated manner along the guide ramp 666.

[0052] It should be noted that the dust filter 665 installed on the collection box 664 can prevent grinding debris from directly entering the piston cavity.

A transmission shaft is arranged at the center of the pulley 71 on the other side, a gear 73 is arranged on the transmission shaft, and a first gear rod 74 is meshed with the gear 73. In this design, through the rotating rod 56 driven by the flipping motor connected to the lower end of the bracket 51 and the corresponding side of the working groove 1, and two symmetrical pulleys 71 are mounted on the rotating rod 56, and the transmission belts 72 respectively wrapped around the two pulleys 71 and the pulley 71 of the same structure wrapped around the other side of the transmission belt 72, when the flipping motor drives the rotating rod 56 to rotate, it will synchronously drive the two groups of belt transmission structures composed of pulleys 71 and transmission belts 72 installed on the rotating rod 56, so that the gear 73 mounted in the middle of the transmission shaft mounted at the center of the end face of the pulley 71 wrapped around the other side of the transmission belt 72 moves synchronously, and then the first gear rod 74 meshing externally on the gear 73 moves vertically.

With such a design, through the external threaded rotating rod 75 welded on the upper end of the first gear rod 74, and the internal threaded sleeve 76 rotatably matched with the external thread of the external threaded rotating rod 75, when the first gear rod 74 is subjected to a vertical motion force, on the one hand, the external threaded rotating rod 75 welded on the upper end of the first gear rod 74 is driven to move vertically, and on the other hand, the internal threaded sleeve 76 rotatably connected to the bottom surface of the working groove 1 is driven to perform a circular motion through the rotational cooperation of the external threaded rotating rod 75 and the internal threaded sleeve 76, thereby generating a force transmission.

[0056] In one embodiment, a push rod 8 for pushing out the block of zinc alloy is fixed at the top of the external threaded rotating rod 75. With this design, once the first toothed rod 74 is subjected to a force, the push rod 8 welded at the top of the external threaded rotating rod 75 will synchronously drive the integrated structure welded by the first toothed rod 74, the external threaded rotating rod 75, and the push rod 8 to move upward, exerting a force for pushing out, and assisting in supporting the block of zinc alloy that has been pre-treated by grinding to flip outward.

[0057] In one embodiment, the outer ends of the inner thread sleeve 76 are provided with a transmission mechanism 9 for transmission with the clamping mechanism 4 through a support rod;

[0058] The second transmission mechanism 9 includes an inner gear ring 91 fixedly disposed on the outside of the support rod and rotatably disposed on the working groove 1, a double gear 92 disposed in the inner gear ring 91 and corresponding to the guide rod 42, and a second gear rod 93 meshing with the double gear 92;

In this design, the inner gear ring 91 is welded and installed outside the support rod welded on the internal threaded sleeve 76, and the inner gear ring 91 is connected to the bottom surface of the working groove 1 through rotation.

[0060] It should be noted that the double gear 92 adopts two gear parts, and the rotating shaft is coaxially installed on the two gear parts, wherein the lower gear part formed on the double gear 92 will be meshed and connected with the inner ring gear 91, and the upper gear part formed on the double gear 92 will be meshed and connected with the second gear rod 93.
