Description

Technical Field

[0001] The utility model belongs to the technical field of concrete protection, and specifically relates to a concrete-embedded sacrificial anode fixing device. Background Art

[0002] A sacrificial anode is an anode material used in a method for preventing metal corrosion; a sacrificial anode is usually made of a metal that is more active than the metal to be protected; common sacrificial anode materials include zinc, aluminum, magnesium, etc.; these metals have relatively low potentials in the natural environment, and when connected to the metal to be protected and in the same electrolyte environment, the sacrificial anode will corrode and dissolve preferentially; in the construction field, the method of using sacrificial anodes is generally used to protect concrete from corrosion, so a sacrificial anode fixing device is required.

[0003] The structure of a sacrificial anode fixing device mainly includes a sacrificial anode material, a fixing structure, a connecting structure, and a sealing structure. Its principle is to embed the sacrificial anode into the concrete through the fixing device so that it forms an electrical connection with metal structures such as steel bars in the concrete; under the action of moisture and oxygen in the concrete, the sacrificial anode will corrode and release electrons, and these electrons will flow to metal structures such as steel bars, thereby reducing the potential of metal structures such as steel bars and achieving the purpose of protecting metal structures such as steel bars from corrosion.

[0004] With the passage of time, shrinkage and expansion of concrete, and the influence of the external environment, the existing concrete-embedded sacrificial anode fixing device may become loose, resulting in the displacement of the sacrificial anode position and affecting the protection effect; and during the concrete pouring process, due to the flow impact or vibration of the concrete, etc., the position of the fixing device may change, thus affecting the correct installation position of the sacrificial anode. Therefore, a concrete-embedded sacrificial anode fixing device is proposed to solve the above problems. Summary of the Utility Model

A chute is opened on one side of the support plate. A slider is slidably connected inside the lower fixing chute. The other end of the slider is welded to connect a second connecting rod. The other end of the second connecting rod is welded to connect a first placement plate. A perforation is opened in the center of the first placement plate. Two groups of first threaded holes are provided on both sides of the perforation. The first threaded holes; a upper fixing platform is provided at the top of the support plate. The lower fixing platform corresponding to the bottom of the support plate is provided at the bottom of the upper fixing platform. A top cover is provided at the top of the lower fixing platform. A dug groove is opened inside the center of the top cover. Six groups of springs are provided at the top of the dug groove inside the top cover. The top of the spring is welded to connect a top plate. A slide rail is provided inside the top plate; with this structural method, the sacrificial anode material can be supported by two placement trays and the device can be fixed by the fixing platforms at both ends, thereby fixing the sacrificial anode material. In this way, it is possible to avoid the problem that as time goes by and due to the shrinkage, expansion of the concrete and the influence of the external environment, the fixing device may become loose, resulting in the displacement of the sacrificial anode position and affecting the protection effect.

[0007] Preferably, a second threaded hole is provided on one side inside the slide rail. The diameter of the second threaded hole is the same as the diameter of the first threaded hole; a second slot is opened at the top of the top plate; a first connecting rod is slidably connected inside the lower fixing platform. The other end of the first connecting rod is welded to connect a second placement plate. A first slot is provided in the center of the second placement plate; by adding springs with damping structures at the bottom of the device to reduce vibration, and by using a limiting plate to fix the sacrificial anode material to avoid the problem that during the concrete pouring process, due to the flow impact or vibration of the concrete and other operations, the position of the fixing device may change, thus affecting the correct installation position of the sacrificial anode.

[0008] Preferably, an object inlet is opened at the top of the first slot. The diameter of the object inlet is the same as the diameter of the sacrificial anode material; a limiting plate is provided at the bottom of the first slot; the position of the first placement plate is at the bottom of the second placement plate; the structure of the upper fixing platform is the same as that of the lower fixing platform; a baffle is provided on one side of the support plate; a bolt is rotatably connected inside the first threaded hole. The bolt passes through the first placement plate and the top plate, and the other end is rotatably connected to the second threaded hole; with this structural design, the stability of the device operation is increased.

[0009] The beneficial effects of the present utility model are as follows:

[0010] With this structural method, the sacrificial anode material can be supported by two sets of storage trays and the device can be fixed by the fixing platform at the long end, thereby fixing the sacrificial anode material. In this way, it is possible to avoid the problem that over time, due to the shrinkage, expansion of the concrete and the influence of the external environment, the fixing device may become loose, resulting in the displacement of the sacrificial anode position and affecting the protection effect. By adding springs with damping structures at the bottom of the device, vibration can be reduced, and the sacrificial anode material can be fixed by the limiting plate to avoid the problem that during the concrete pouring process, due to the flow impact or vibration of the concrete, the position of the fixing device may change, thereby affecting the correct installation position of the sacrificial anode.

A groove is opened inside the center of the top cover 9. Six springs 22 are provided at the top of the groove inside the top cover 9. The top ends of the springs 22 are welded to a top plate 14. A slide rail 17 is provided inside the top plate 14; when fixing the sacrificial anode material, at this time, the operator first places the sacrificial anode material at the material inlet 20, then inserts it into the first slot 8, then inserts the slider 10 at one end of the first placement plate 5 along the track of the chute 21, then inserts the second placement plate 7 into the chute 21, and then inserts another first placement plate 5 to fix the top end of the sacrificial anode material. Then install the upper fixing platform 3 and weld the baffle 2 at the top of the upper fixing platform 3 to the support plate 1; then by rotating the first slot 8, the limiting plate 19 at the bottom of the first slot 8 enters the inside of the slide rail 17 along the notch of the second slot 15. When rotated to the innermost part, at this time, the operator uses a bolt 16 to connect the first placement plate 5 and the top plate 14, thus completing the fixing operation of the sacrificial anode material.

When the pouring operation is completed, when vibrating at this time, the spring 13 at the bottom of the top plate 14 starts to act and absorbs and conducts the generated vibration to the top cover 9 and finally is transmitted out through the lower fixing table 4, thereby reducing the vibration generated by the device during pouring and vibrating, and thus avoiding the device from deviating; when replacing the sacrificial anode material, only need to remove the baffle 2 and draw out the sacrificial anode material from between each storage plate, thereby completing the sacrificial anode protection operation for concrete.

[0021] Working principle: When fixing the sacrificial anode material, first the operator places the sacrificial anode material at the material inlet 20, then inserts it into the first slot 8, then inserts the slider 10 at one end of the first storage plate 5 along the track of the chute 21, then inserts the second storage plate 7 into the chute 21, then inserts another first storage plate 5 to fix the top end of the sacrificial anode material, then installs the upper fixing table 3, and welds the baffle 2 at the top end of the upper fixing table 3 to the support plate 1; then by rotating the first slot 8, the limiting plate 19 at the bottom of the first slot 8 enters the inside of the slide rail 17 along the notch of the second slot 15.
