Description

Technical Field

[0001] The invention belongs to the technical field of chemical devices, and in particular relates to a sacrificial anode electrochemical automatic detection device. Background Art

[0002] Sacrificial anode refers to the anode (metal) that is gradually consumed as the current flows out when the theoretical metal of the electrolytic cell is used as the anode. Sacrificial anodes are usually only used economically in structures with small protection current requirements and in low soil resistivity environments. The main process of the existing sacrificial anode test is: 1. Process the anode sample, and the non-working surfaces at both ends of the anode sample and the water-immersed parts of the copper rod are sealed with highly insulating materials, such as wax; 2. Connect the test device, and immerse the aluminum anode sample in the medium; 3. Conduct a power-on test and record data according to the standard. In the connected test device, the aluminum anode sample is immersed in the medium. Now a sample is immersed in a stainless steel ring, and the positive and negative poles of the power supply are connected respectively. The disadvantage of this method is low efficiency. The wiring is complicated and the overall appearance is messy. Because the sample is suspended by a wire, it is easy to shake and hit the wall, causing errors. Summary of the invention

[0003] The purpose of the present invention is to provide a sacrificial anode electrochemical automatic detection device. Through a support frame, the device can fix the sample on a copper rod, instead of hanging it with a wire as before. It will not shake, thus avoiding errors in the experimental results due to shaking. The shortcomings of the traditional method are low efficiency, complex wiring, and a messy overall appearance. Since the sample is suspended by a wire, it is easy to shake and hit the wall, causing errors.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a sacrificial anode electrochemical automatic detection device, comprising a base, a plurality of copper rods are fixed on the upper surface of the base, the copper rods are vertically fixed on the upper surface of the base and arranged in parallel, and the upper surface of the copper rods is provided with through holes;

[0006] A plurality of limiting grooves are fixed on the upper surface of the base, the distance between two adjacent limiting grooves is equal, and a beaker is movably connected inside the limiting groove;

[0007] A connecting rod is movably connected inside the through hole, a mounting plate is fixed to one end of the connecting rod, and a stainless steel ring is fixed to one side of the mounting plate;

[0008] Both sides of the base are provided with positioning grooves, the positioning grooves are movably connected with positioning blocks, one side of the positioning blocks is fixed with a support frame, and the upper surface of the support frame is fixed with an adjustment rod;

[0009] The adjusting rod is hollow, a threaded rod is movably connected inside the adjusting rod, and a movable rod is fixed at one end of the threaded rod;

[0010] A connecting block is fixed at one end of the movable rod, a supporting plate is fixed at one side of the connecting block, a plurality of positioning rods are vertically fixed at one side of the supporting plate, the positioning rods are arranged in parallel, and a sample is fixed at one end of the positioning rod;

[0011] A circuit breaker is electrically connected between the copper bars.

[0012] Furthermore, a first rotating shaft is fixed to one end of the adjusting rod, and a threaded tube is fixed to the inner ring of the first rotating shaft.

[0013] Furthermore, the threaded tube is threadedly connected to the threaded rod, a rotating rod is fixed to one end of the threaded rod, and a second rotating shaft is fixed to the outer side of the rotating rod.

[0014] Furthermore, a movable plate is fixed to the outer ring of the second rotating shaft, and a plurality of first adjusting blocks are fixed to the outer side of the rotating rod.

[0015] Furthermore, a forward and reverse motor is fixed to one side of the support frame, a transmission rod is fixed to the output shaft of the forward and reverse motor, a third rotating shaft is fixed to one end of the transmission rod, and an outer ring of the third rotating shaft is fixedly connected to the movable plate.

[0016] Furthermore, a plurality of second adjustment blocks are fixed on the outside of the transmission rod, and the second adjustment blocks are fixed on the outside of the transmission rod at equal distances with the transmission rod as the axis, and a transmission belt is sleeved on the outside of the first adjustment block and the second adjustment block.

[0017] Furthermore, a telescopic rod is fixed between the movable plate and the supporting frame.

[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention uses a support frame, which can fix the sample on the copper rod instead of hanging it with a wire as in the past, so that it will not shake, thus avoiding errors in the experimental results caused by shaking.

[0020] 2. The present invention uses a circuit breaker to facilitate the wiring of the device. No matter how many samples there are, only two positive and negative wires are needed, which solves the problem of multiple and complicated wires in the past.

[0021] 3. The present invention greatly saves the use of test power supply by setting multiple limit slots to work simultaneously. Previously, one power supply was required for every three samples, but this device only needs one power supply, which not only improves work efficiency but also makes the device reliable and safe.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
