Description

Technical field:

[0002] The invention relates to a test device in a corrosive environment, in particular to a wave erosion machine. Background technology:

[0004] The research on seawater impact corrosion is mainly based on the analysis of actual seaside hanging pieces, but this method has a long cycle, high cost, many influencing factors, and it is difficult to observe the corrosion state of the sample in real time. In view of this, the invention of a test device simulating seawater impact corrosion can shorten the cycle and facilitate research in the field of material corrosion and protection.

[0005] At present, relevant patents have been published. Zhang Weimin and others from China University of Petroleum invented an erosion-corrosion experimental device (201510257018.4) that simulates the dry-wet alternating environment in the splash zone through a nozzle. Chen Xiaoming and others from the Product Quality Standards Institute of the Ministry of Water Resources invented an experimental device and method for multi-factor interactive corrosion in a simulated marine service environment (CN202010365236.0), which uses a stirrer with a continuously variable speed control to rotate and beat in a seawater corrosion test tank to simulate the movement of seawater stirring liquid and generate waves.

[0006] The way these two experimental methods generate waves is very different from the way waves are generated by the impact of waves in the actual ocean, and it is impossible to make the waves hit the test samples head-on. Summary of the invention:

[0008] The present invention aims to overcome the deficiencies in the prior art and provide a wave erosion machine.

[0013] The sample placement rack comprises a base plate, on which a group of clamping strips are evenly distributed, a top plate is arranged between two clamping strips, and a group of buffer components is arranged between the top plate and the base plate.

[0014] The clamping strip comprises a vertical portion, a horizontal portion is distributed at one end of the vertical portion, protrusions are extended from both ends of the horizontal portion, and buffer grooves made of elastic material are arranged on the protrusions.

[0015] Advantages of the invention:

[0016] The present invention has a simple structure and is easy to use. The moving plate moves in the box to drive the corrosion liquid to simulate the front impact of the sea waves on the sample of the corrosion sample placement rack. In addition, the buffer component is set so that the distance between the protrusion and the top plate has a constant variable, so that the device is suitable for samples of different thicknesses. Description of the drawings:

[0019] Figure 2 yes Figure 1 Schematic diagram of the structure of the sample placement rack. Specific implementation method:

[0021] like Figure 1 and 2 The present invention relates to a wave erosion machine, which comprises a box body 1, and a sample placement rack 2 is installed on a box wall on one side of the box body 1. The sample placement rack 2 comprises a base plate 2a, and a group of strip-shaped clips 2b are evenly distributed on a side surface of the base plate 2a. The clips 2b and the base plate 2a are an integrated structure.

[0022] The clamping strip 2b includes a vertical portion a perpendicular to the surface of the substrate 2a, and a horizontal portion b is distributed at the top of the vertical portion a. The horizontal portion b is parallel to the surface of one side of the substrate 2a, so that the cross section of the clamping strip 2b is a T-shaped structure. Triangular protrusions c extend toward the substrate 2a at both ends of the horizontal portion b, and a sample limiting groove is formed by the protrusion c and the vertical portion a. A buffer layer d made of elastic material is bonded to the protrusion c, and the elastic material is made of rubber or silicone.

[0023] A top plate 2c is also distributed on the surface of the base plate 2a between two adjacent clip strips 2b, and a group of buffer components 2d are evenly distributed between the top plate 2c and the base plate 2a, and are connected by the buffer components 2d. The buffer components 2d are rubber blocks or silicone blocks or springs. The base plate 2a, top plate 2c and clip strips 2b are all made of polypropylene.

[0024] A movable plate 3 is arranged in parallel with the sample placement frame 2 in the box body 1, and a wave-shaped protrusion 3a extends from the opposite surface of the movable plate 3 and the base plate 2a. A push rod 4 is passed through the box body 1, one end of the push rod 4 is located outside the box body 1, and the other end is fixedly connected to the movable plate 3.

[0025] A rack 4a is provided at one end of the push rod 4 located outside the housing 1. A transmission device 5 corresponding to the rack 4a is provided outside the housing 1. The transmission device 5 includes a motor 5a, a driving wheel 5f is connected to the output shaft of the motor 5a, a base is provided on one side of the motor 5a, a rotating shaft is passed through the base, a transmission wheel 5b is connected to one end of the rotating shaft, and the driving wheel 5f and the transmission wheel 5b are provided with a belt forming a transmission match.

[0026] The motor drives the sector gear 5d to swing, drives the push rod 4 to reciprocate, drives the moving plate 3 to reciprocate, and drives the corrosive liquid (artificial seawater) in the box to impact the sample plate. Due to the existence of the wavy protrusion 3a, the moving plate 3 pushes the corrosive liquid to form a wave effect of the sea waves.

[0027] The transmission device 5 can also be a cylinder in the prior art. The structure of the transmission device 5 disclosed in this specification enables the reciprocating motion of the moving plate 3 to have the effect of gradually accelerating and gradually reducing, which can better simulate the effect of sea waves.
