Description

Technical Field

[0001] The utility model belongs to the technical field of corrosion prevention, and in particular relates to a cathode corrosion prevention device using an impressed current method. Background Art

[0002] The working principle of impressed current cathodic protection is based on the basic principle of electrochemical corrosion. In a corrosive environment, metals easily lose electrons and become anodes, and then undergo oxidation reactions (i.e. corrosion). The impressed current cathodic protection method uses an external DC power supply to make the protected metal structure a cathode, thereby accepting electrons flowing from the anode (auxiliary anode) to prevent it from losing electrons and corroding. Specifically, the current flows out from the positive electrode of the DC power supply, passes through the auxiliary anode into the soil (or other electrolyte), then flows through the electrolyte to the protected metal structure (i.e. cathode), and finally flows back to the negative electrode of the DC power supply to form a closed circuit.

[0003] The existing utility model patent CN 215481277 U is a cathode anti-corrosion device using impressed current method. Generally, there is an observation deck on the beach to protect people's safety. If danger occurs, people can stand at the highest point to see the position of people who fall into the water, so as to quickly reach the target position. However, the observation deck has been in the shallow sea. The corrosion of sea water will damage the bracket of the observation deck, posing a threat to the lives of people on the observation deck. The utility model is provided with multiple groups of zinc plates, which increase the contact area between the zinc plates and the sea water. The locking device can be used to quickly replace the zinc plates, thereby improving the replacement efficiency. The driving screw can lift the zinc plates and replace the zinc plates in a safe position. The structure is simple, practical, and highly automated, which saves people's labor and improves the efficiency of installation.

[0004] The above design uses an ingenious combination of mechanisms and an impressed current cathodic protection method to protect the bracket of the observation deck from corrosion, and uses a locking device to facilitate the replacement of the zinc plate. However, the above design is not convenient for quickly limiting the outdoor power supply during use. Utility Model Content

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0027] like Figures 1 to 6A cathode anti-corrosion device using an impressed current method includes: an outdoor power supply box 1, a raw material shell 2, an observation platform bracket 3 and a clamping mechanism 4. The raw material shell 2 is arranged on the right side of the outdoor power supply box 1, and the observation platform bracket 3 is arranged on the left side of the outdoor power supply box 1. The clamping mechanism 4 is installed on the lower surface of the outdoor power supply box 1. The clamping mechanism 4 includes a clamping mounting shell 41, a first clamping plate 42 and a second clamping plate 43. The bottom of the outdoor power supply box 1 is provided with a clamping mounting shell 41, and the inner wall of the clamping mounting shell 41 is symmetrically slidably connected with the first clamping plate 42 and the second clamping plate 43.

[0028] In this embodiment, when the observation platform bracket 3 soaked in seawater needs to be treated for corrosion, the zinc plate is placed in the slot of the raw material shell 2, the anode circuit of the outdoor power box 1 is connected to the raw material shell 2, and the cathode circuit of the outdoor power box 1 is connected to the observation platform bracket 3. The observation platform bracket 3 is protected against corrosion by an impressed current cathodic protection method. The power supply of the outdoor power box 1 is started to make the metal structure of the observation platform bracket 3 a cathode to receive electrons sent from the zinc plate inside the raw material shell 2. The first clamping plate 42 and the second clamping plate 43 on the inner wall of the clamping installation shell 41 are close to each other, and the rectangular grooves of the first clamping plate 42 and the second clamping plate 43 contact the bottom of the outdoor power box 1 to quickly fix the outdoor power box 1.

[0029] As attached Figure 4 As shown, the clamping mechanism 4 also includes a connecting gear 44, a first rack 45 and a second rack 46. The inner wall of the clamping mounting shell 41 is rotatably connected with the connecting gear 44. The first rack 45 is fixedly connected to the surface of the rectangular block on the lower surface of the first clamping plate 42 close to the connecting gear 44, and the first rack 45 is slidably connected with the rectangular hole of the rectangular block on the lower surface of the second clamping plate 43. The second rack 46 is fixedly connected to the surface of the rectangular block on the lower surface of the second clamping plate 43 close to the connecting gear 44, and the second rack 46 is slidably connected with the rectangular hole of the rectangular block on the lower surface of the first clamping plate 42. The side teeth of the connecting gear 44 are meshed with the teeth on the surface of the first rack 45 and the second rack 46.

[0030] In this embodiment, the first clamping plate 42 is close to the second clamping plate 43. Since the gear teeth on the side of the linkage gear 44 are meshed with the gear teeth on the surface of the first rack 45 and the second rack 46, when the first clamping plate 42 is close to the second clamping plate 43, the second clamping plate 43 is close to the first clamping plate 42 at the same time, and the first rack 45 enters the rectangular hole of the rectangular block on the lower surface of the second clamping plate 43, and the second rack 46 enters the rectangular hole of the rectangular block on the lower surface of the first clamping plate 42, so as to facilitate the outdoor power box 1 to be firmly fixed.

[0031] As attached Figure 4As shown, the clamping mechanism 4 also includes a moving block 47, a first screw rod 48 and a rotating disk 49. The moving block 47 is fixedly connected to the bottom of the rectangular block on the lower surface of the first clamping plate 42, and the moving block 47 slides on the inner wall of the clamping mounting shell 41. The side of the clamping mounting shell 41 away from the first clamping plate 42 is rotatably connected to the first screw rod 48, and the first screw rod 48 passes through the inner wall of the clamping mounting shell 41. The threaded surface of the first screw rod 48 is meshed with the inner wall of the circular hole of the moving block 47, and the side of the first screw rod 48 away from the moving block 47 is fixedly connected to the rotating disk 49.

[0032] In this embodiment, the rotating disk 49 is rotated to rotate the first screw 48 clamping the inner wall of the mounting shell 41 , and the threaded surface of the first screw 48 contacts the inner wall of the circular hole of the moving block 47 , driving the first clamping plate 42 to approach the second clamping plate 43 .

[0033] As attached Figure 5 As shown, a lifting mechanism 5 is fixedly installed on the lower surface of the clamping and mounting shell 41, and the lifting mechanism 5 includes a first lifting plate 51, a second lifting plate 52, a guide seat 53 and a guide frame 54. The first lifting plate 51 is fixedly connected to the lower surface of the clamping and mounting shell 41, and a second lifting plate 52 is arranged below the first lifting plate 51. The upper surface of the second lifting plate 52 is symmetrically fixedly connected to the guide seat 53, and the lower surface of the first lifting plate 51 is symmetrically fixedly connected to the guide frame 54, and the guide frame 54 is slidably connected to the inner wall of the rectangular groove of the guide seat 53.

[0034] In this embodiment, when the sea water level is high, in order to prevent the outdoor power box 1 from contacting the sea water, the guide frame 54 moves upward along the rectangular groove of the guide seat 53, driving the first lifting plate 51 away from the second lifting plate 52, thereby adjusting the height of the outdoor power box 1.

[0035] As attached Figure 6 As shown, the lifting mechanism 5 also includes an adjusting rod 55, a rotating seat 56, a second screw rod 57 and a rotating rod 58. An adjusting rod 55 is arranged in the middle of the two guide seats 53, and the bottom of the adjusting rod 55 is fixedly connected to the upper surface of the second lifting plate 52. A rotating seat 56 is arranged above the adjusting rod 55, and the upper surface of the rotating seat 56 is fixedly connected to the lower surface of the first lifting plate 51. The second screw rod 57 is rotatably connected to the inner wall of the circular hole at the bottom of the rotating seat 56, and the threaded surface of the second screw rod 57 is meshed with the inner wall of the circular groove of the adjusting rod 55. The rotating rod 58 is rotatably connected to the inner wall of the circular hole on the side of the rotating seat 56, and the side of the rotating rod 58 close to the second screw rod 57 is meshed with the top of the second screw rod 57 through a bevel gear.

[0036] In this embodiment, a driving block on one side of the rotating rod 58 is rotated to drive the rotating rod 58 to rotate on the inner wall of the circular hole on the side of the rotating seat 56. The bevel gear on the side of the rotating rod 58 close to the second screw rod 57 contacts the bevel gear on the top of the second screw rod 57, driving the upper end of the second screw rod 57 to rotate on the inner wall of the circular hole at the bottom of the rotating seat 56. Since the threaded surface of the second screw rod 57 is meshed and connected with the inner wall of the circular groove of the adjusting rod 55, when the second screw rod 57 rotates, the adjusting rod 55 is controlled to move away from the rotating seat 56 to adjust the height of the first lifting plate 51.

[0037] As attached Figure 1 and Figure 2 As shown, the anode of the outdoor power box 1 is electrically connected to the raw material shell 2 through a line, and the cathode of the outdoor power box 1 is electrically connected to the observation platform bracket 3 through a line.

[0038] In this embodiment, the principle of impressed current cathodic protection is used to prevent the observation platform bracket 3 from losing electrons and to provide anti-corrosion protection.
