Description

Technical Field

[0001] The utility model belongs to the technical field of magnesium alloy sacrificial anodes, and particularly relates to a detachable magnesium alloy sacrificial anode. Background Art

[0002] The detachable magnesium alloy sacrificial anode is a device specifically used for a cathodic protection system, mainly used to provide electrochemical protection for metal structures to prevent or slow down the corrosion process. In the prior art, a clamp assembly for fixing it is usually provided on the sacrificial anode. The clamp assembly is divided into a left clamp and a right clamp. One end of the left clamp and the right clamp is hinged, and the other end is connected through a fastening seat and a bolt. However, in this method, when using the fastening bolt and the fastening seat for fixed connection, when replacing the magnesium alloy sacrificial anode, workers need to use other tools to assist in disassembling the fastening bolt, replacing it, and then installing it, which is time-consuming and laborious.

[0003] For example, the utility model with the publication number CN212864985U discloses a clamped magnesium alloy sacrificial anode. In the technical solution of this patent, a clamp assembly connected to it is provided on the magnesium alloy sacrificial anode to fix it on the protected structure. The clamp assembly includes a left clamp and a right clamp. One end of the left clamp and the right clamp is hinged, and the other end is provided with fastening seats on both the left clamp and the right clamp, and then the left clamp and the right clamp are fixed by passing a fastening bolt through the fastening seat, thereby fixing the magnesium alloy sacrificial anode. However, in this method, when fixing the left clamp and the right clamp through the fastening bolt and the fastening seat, workers need to use additional tools to assist in disassembling the fastening bolt, and after replacing the magnesium alloy sacrificial anode, use tools to install and fix it, which increases the complexity and difficulty of on-site operations and reduces work efficiency. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a detachable magnesium alloy sacrificial anode, which can not only fix the magnesium alloy sacrificial anode through the clamp assembly to provide electrochemical protection for metal structures to prevent or slow down the corrosion process, but also can be quickly replaced conveniently through the fixing component, improving work efficiency.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A detachable magnesium alloy sacrificial anode, comprising an anode body and a clamp assembly fixedly connected to the anode body. The clamp assembly includes a left clamp and a right clamp. Conductive rods are provided on the left clamp. One end of the left clamp and the right clamp is hinged. A fixing assembly for fixing the left clamp and the right clamp is provided on the clamp assembly. The fixing assembly includes a first fixing member provided on the left clamp and a second fixing member provided on the right clamp. The second fixing member includes a fixing seat provided on the right clamp. A fixing plate adapted to the groove is provided at the left end of the fixing seat.

[0009] As a further improvement of the present utility model, a support plate is provided on the left clamp. Iron cores are provided at the upper and lower ends of the anode body. The two iron cores are respectively fixed on the adjacent support plates.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] First, by providing the fixing assembly, when it is necessary to disassemble the magnesium alloy sacrificial anode, the pull rods are respectively pulled upward and downward. The pull rods cause the sliding plates to compress the springs and move upward and downward respectively. The pin columns on the sliding plates move accordingly, so that the pin columns are disengaged from the slots on the fixing plate, so as to disengage the fixing plate from the groove inside the mounting frame, so as to facilitate the quick disassembly of the left clamp and the right clamp.

[0012] Second, by providing the first fixing member and the second fixing member, the left clamp and the right clamp can be jointly fixed outside the pipeline, so as to facilitate the quick fixing of the magnesium alloy sacrificial anode.

[0013] Third, by providing the conductive rods, the conductive rods are directly connected to the sacrificial anode and the protected structure, which can ensure the smooth transmission of current, improve the effectiveness and efficiency of electrochemical protection, and reduce the resistance loss.

[0014] Fourthly, pull rings are provided at the ends of the pull rods away from the mounting brackets. The design of the pull rings enables the operator to easily pull the pull rods, facilitating the disassembly and installation of the anode. Brief Description of the Drawings

Specific Embodiments

[0021] To better understand the present utility model, the content of the present utility model will be further clearly described below in conjunction with embodiments. However, the protection scope of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0022] As Figure 1 , 2 , shown in Figure 3, a detachable magnesium alloy sacrificial anode includes an anode body 101 and a clamp assembly fixedly connected to the anode body 101. The clamp assembly includes a left clamp 102 and a right clamp 103. A conductive rod 104 is provided on each group of left clamps 102. One end of the left clamp 102 is hinged to one end of the right clamp 103. A fixing component for fixing the left clamp 102 and the right clamp 103 is provided on the clamp assembly. The fixing component includes a first fixing member provided on the left clamp 102 and a second fixing member provided on the right clamp 103. The provided first fixing member and second fixing member can fix the left clamp 102 and the right clamp 103 outside the protected structure to facilitate the fixation of the magnesium alloy sacrificial anode.

[0023] As Figure 1 ,2 As shown in the figure, the first fixing member includes a mounting bracket 201 provided on the left clamp 102. Symmetrical sliding grooves 202 are formed on the upper and lower sides inside the mounting bracket 201. Slide plates 203 are slidably arranged inside the sliding grooves 202. The left ends of the slide plates 203 are respectively connected with pull rods 204. The pull rods 204 are slidably connected with the mounting bracket 201. Springs 205 are sleeved on the ends of the pull rods 204 located inside the mounting bracket 201. One end of each spring 205 is connected to the side wall of the corresponding slide plate 203, and the other end is respectively connected to the inner side wall of the adjacent mounting bracket 201. A groove is formed in the middle of the mounting bracket 201. Pin posts 206 are arranged on the opposite sides of the slide plates 203. The second fixing member includes a fixing seat 207 provided on the right clamp 103. A fixing plate 208 adapted to the groove is arranged at the left end of the fixing seat 207. A slot 209 adapted to the pin post 206 is formed on the side wall of the fixing plate 208.

[0024] As Figure 1 、 4 shown, there are at least two sets of clamp assemblies.

[0025] As Figure 1 、 4 shown, a support plate 105 is arranged on the left clamp 102. Iron cores 106 are arranged at the upper and lower ends of the anode body 101. The two iron cores 106 are respectively fixed on the adjacent support plates 105.

[0026] During use, when it is necessary to disassemble the magnesium alloy sacrificial anode, pull the pull rings 210 towards the upper and lower ends respectively. The pull rings 210 pull the pull rods 204 to move towards the upper and lower ends. The pull rods 204 pull the slide plates 203 to move along the sliding grooves 202. At this time, the springs 205 are in a compressed state. The pin posts 206 move towards the upper and lower ends respectively with the slide plates 203, so that the pin posts 206 are disengaged from the slots 209 on the fixing plate 208. Then move the fixing plate 208 to the right end to disengage the fixing plate 208 from the groove inside the mounting bracket 201, so as to separate the left clamp 102 from the right clamp 103, facilitating its quick disassembly.
