Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a walk-in periodic immersion experimental device. Background Technology

[0002] A walk-in immersion test apparatus is an experimental device used to simulate the periodic wet-dry alternation and corrosive media action of materials in specific environments (such as marine or industrial atmospheres). Its core function is to evaluate the corrosion resistance and lifespan of materials or coatings by precisely controlling environmental parameters (temperature, humidity, wetting medium, wet-dry cycle, etc.).

[0003] A search revealed a utility model patent (CN220854547U) for a walk-in periodic immersion test device, comprising an environmental chamber, a main frame, a lifting device, a heating device, a dehumidifying device, and a humidifying device. The heating, dehumidifying, and humidifying devices are all located outside the environmental chamber, providing sufficient space for the interior and preventing fluctuations in environmental parameters caused by these devices operating inside the chamber. An air inlet is located at the top of the environmental chamber, and an air outlet is located on the rear wall panel, creating a bottom-out, top-in circulation flow within the chamber. This uniform air outlet layout, combined with a control system, enables precise control of temperature and humidity parameters within a designated area. This results in efficient and uniform medium circulation within the environmental chamber, improving the accuracy and efficiency of temperature and humidity control. The use of a single winch effectively solves the synchronization problem during sample lifting, avoiding the asynchrony issues that can occur when using two winches and preventing tilting of the sample in the vertical direction.

[0004] Although the aforementioned patent utilizes the bottom-out, top-in circulation process of airflow within the environmental chamber, along with a uniform vent layout and a control system, to achieve temperature and humidity parameter control within a designated area, resulting in efficient and uniform medium circulation and improved temperature and humidity control accuracy and efficiency, the actual cyclic immersion process requires the sample to be immersed in liquids of different compositions in different cycles to better simulate the sample's state in a real environment. This necessitates the sample being immersed in different solution pools during the cyclic immersion process, while existing experimental equipment generally can only hold one type of solution pool, thus limiting the experimental equipment to certain extent.

[0005] Therefore, it is necessary to propose a walk-in periodic immersion experimental device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a walk-in periodic immersion experimental device. Through the cooperation of the internal parts of the experimental mechanism, it is easy to place multiple samples in the sample chamber, allowing the main body of the device to simultaneously carry multiple samples for immersion experiments. Furthermore, it allows for the selection of solution pools with different compositions during the periodic immersion process. The cooperation of the internal parts of the moving mechanism facilitates the horizontal movement of the sample chamber, allowing it to move above multiple solution pools, and also facilitates the vertical movement of the sample chamber, enabling the sample chamber to vertically immerse the sample in the solution. This addresses the problem in existing technologies where samples need to be immersed in liquids of different compositions in different periods to better simulate the sample's state in a real environment, resulting in the need for different solution pools during periodic immersion. However, existing experimental devices generally can only hold one type of solution pool, thus limiting the limitations of the experimental equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a walk-in periodic immersion test device, comprising a device body, an experimental mechanism installed at the top of the device body and extending into the interior of the device body, and a moving mechanism rotatably connected to both sides of the interior of the device body and located on both sides of the experimental mechanism;

[0008] The experimental mechanism includes a sample chamber, which is slidably connected to the inside of the main body of the equipment. Multiple partitions are slidably connected to the top of the sample chamber, and the outer wall of the partitions is mechanically connected to elastic blocks and fits against the inner wall of the sample chamber.

[0009] The moving mechanism includes a servo motor, which is fixed to both sides inside the main body of the equipment by bolts. The output shaft of the servo motor is rotatably connected to a threaded rod via a coupling. The outer wall of the threaded rod is threadedly fitted with a sliding base and slidably connected to the inside of the main body of the equipment. The top of the sliding base is fixed to a drive motor by bolts, and the output shaft of the top of the drive motor is rotatably connected to a reciprocating screw via a coupling. The outer wall of the reciprocating screw is slidably fitted with a connecting bracket via a sliding groove, and the connecting bracket is mechanically connected to both sides of the sample chamber.

[0010] Preferably, the experimental apparatus further includes a ventilation duct installed at the top of the main body of the equipment. An air outlet assembly is installed on the inner wall of the main body of the equipment and is connected to the ventilation duct and located above the sample chamber. A solution pool is placed on the inner wall of the main body of the equipment and located below the sample chamber.

[0011] Preferably, the inner walls of the sample chamber have multiple grooves, and the inner walls of the grooves are provided with slots that match the elastic blocks. The surface and bottom of the sample chamber are provided with through holes.

[0012] Preferably, the device body has a horizontal groove inside that matches the sliding base, and the inner wall of the sliding base has an internal thread that matches the thread on the outer wall of the threaded rod.

[0013] Preferably, the main body of the device has a vertical sliding groove inside that matches the connecting bracket, the inner wall of the connecting bracket has a connecting groove that matches the reciprocating screw, and a slider that matches the reciprocating sliding groove on the outer wall of the reciprocating screw is installed inside the connecting bracket.

[0014] Preferably, the bottom ends of the multiple solution pools are sealed with inlet pipes and outlet pipes, which pass through the main body of the equipment and are connected to the external container. The ventilation duct is equipped with an air valve, the surface of the air outlet assembly is provided with multiple ventilation pipes, and the air outlet assembly includes an electric heating wire module and a humidification module inside.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By starting the servo motor, the servo motor drives the threaded rod to rotate. The rotation of the threaded rod causes the sliding base to move horizontally. The horizontal movement of the sliding base drives the connecting bracket to move through the reciprocating screw. The movement of the connecting bracket causes the sample chamber to move above multiple solution pools with different components, so that the sample can be immersed in solutions of different components during the periodic immersion process, thereby better placing the sample in a realistic environment. By starting the drive motor to drive the reciprocating screw to rotate, the reciprocating screw drives the connecting bracket to move vertically. The vertical movement of the connecting bracket causes the sample chamber to sink into the solution pool or move upward into the air outlet assembly. This allows the sample to select solution pools with different components during the periodic immersion process, and facilitates the main body of the equipment to complete the periodic immersion work.

[0017] 2. Multiple solution pools are sealed at the bottom with inlet and outlet pipes, which run through the main body of the equipment and connect to an external container. This allows for the storage of solutions with different compositions in multiple solution pools, enabling the use of various solution pools during sample immersion. Air valves are installed on the ventilation ducts, which are connected to the air outlet assembly to facilitate air circulation within the main body of the equipment. Multiple ventilation pipes are provided on the surface of the air outlet assembly, which includes a heating wire module and a humidification module. This allows the air outlet assembly to humidify or heat the airflow inside the ventilation ducts, thereby better simulating the immersion environment of the sample. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-4 The illustrated walk-in periodic immersion test device includes a device body 1, an experimental mechanism 2 installed at the top of the device body 1 and extending into the interior of the device body 1, and a moving mechanism 3 rotatably connected to both sides of the interior of the device body 1 and located on both sides of the experimental mechanism 2.

[0027] The experimental apparatus 2 includes a sample chamber 204, which is slidably connected to the inside of the main body 1. Multiple partitions 205 are slidably connected to the top of the sample chamber 204. The outer wall of the partitions 205 is mechanically connected to elastic blocks 206, which are in contact with the inner wall of the sample chamber 204.

[0028] The moving mechanism 3 includes a servo motor 301, which is fixed to both sides inside the main body 1 by bolts. The output shaft of the servo motor 301 is rotatably connected to a threaded rod 302 through a coupling. The outer wall of the threaded rod 302 is threadedly fitted with a sliding base 303 and slidably connected to the inside of the main body 1. The top of the sliding base 303 is fixed to a drive motor 304 by bolts. The output shaft at the top of the drive motor 304 is rotatably connected to a reciprocating screw 305 through a coupling. The outer wall of the reciprocating screw 305 is slidably fitted with a connecting bracket 306 through a sliding groove. The connecting bracket 306 is mechanically connected to both sides of the sample chamber 204.

[0029] The interaction between the internal parts of the experimental mechanism 2 facilitates the placement of multiple samples in the sample chamber 204, allowing the main body of the equipment 1 to simultaneously carry multiple samples for immersion experiments. It also allows for the selection of solution pools 203 with different compositions during the periodic immersion process. The interaction between the internal parts of the moving mechanism 3 facilitates the horizontal movement of the sample chamber 204, enabling it to move above multiple solution pools 203. Furthermore, it facilitates the vertical movement of the sample chamber 204, allowing it to vertically immerse the sample in the solution.

[0030] Refer to the instruction manual appendix Figure 1-4 The experimental apparatus 2 also includes a ventilation duct 201, which is installed at the top of the main body 1. An air outlet assembly 202 is installed on the inner wall of the main body 1 and is connected to the ventilation duct 201 and located above the sample chamber 204. A solution pool 203 is placed on the inner wall of the main body 1 and located below the sample chamber 204. Through the cooperation of the internal parts of the experimental apparatus 2, multiple solution pools 203 are arranged inside the main body 1 to facilitate the simulation of sample immersion in different solutions during the cycle.

[0031] Refer to the instruction manual appendix Figure 1-4 The inner wall of the sample chamber 204 has multiple grooves, and the inner wall of the grooves is provided with slots that match the elastic block 206. The surface and bottom of the sample chamber 204 are provided with through holes. The multiple grooves in the inner wall of the sample chamber 204 and the slots that match the elastic block 206 make it easy for the space in the sample chamber 204 to be adjusted by moving the partition 205, so that the sample chamber 204 can accommodate samples of different sizes.

[0032] Refer to the instruction manual appendix Figure 1-4 The device body 1 has a horizontal groove inside that matches the sliding base 303, and the inner wall of the sliding base 303 has an internal thread that matches the thread on the outer wall of the threaded rod 302. The horizontal groove inside the device body 1 that matches the sliding base 303 and the internal thread on the inner wall of the sliding base 303 that matches the thread on the outer wall of the threaded rod 302 facilitate the rotation of the threaded rod 302 to drive the sliding base 303 to move horizontally.

[0033] Refer to the instruction manual appendix Figure 1-4The device body 1 has a vertical sliding groove inside that matches the connecting bracket 306. The inner wall of the connecting bracket 306 has a connecting groove that matches the reciprocating screw 305. The connecting bracket 306 also has a slider inside that matches the reciprocating sliding groove on the outer wall of the reciprocating screw 305. The vertical sliding groove inside the device body 1 that matches the connecting bracket 306 and the connecting groove on the inner wall of the connecting bracket 306 that matches the reciprocating screw 305 facilitates the rotation of the reciprocating screw 305 to drive the connecting bracket 306 to move up and down, thereby allowing the sample chamber 204 to move and immerse itself in the solution pool 203.

[0034] Refer to the instruction manual appendix Figure 1-4 Multiple solution pools 203 are sealed at their bottom ends with inlet and outlet pipes, which pass through the main body 1 of the equipment and connect to the external container. A wind valve is installed on the ventilation duct 201. Multiple ventilation pipes are provided on the surface of the air outlet component 202. The air outlet component 202 includes a heating wire module and a humidification module. The multiple ventilation pipes on the surface of the air outlet component 202 and the heating wire module and humidification module inside the air outlet component 202 facilitate the air outlet component 202 to humidify or heat the airflow inside the ventilation duct 201, thereby better simulating the immersion environment of the sample.

[0035] The working principle of this practical application is as follows:

[0036] Refer to the instruction manual appendix Figure 1-4 By activating the servo motor 301, the servo motor 301 drives the threaded rod 302 to rotate. The rotation of the threaded rod 302 causes the sliding base 303 to move horizontally. The horizontal movement of the sliding base 303 drives the connecting bracket 306 to move via the reciprocating screw 305. The movement of the connecting bracket 306 causes the sample chamber 204 to move above multiple solution pools 203 with different components, allowing the sample to be immersed in solutions of different components during periodic immersion, thus better placing the sample in a realistic environment. By activating the drive motor 304, the reciprocating screw 305 is driven to rotate. The rotation of the reciprocating screw 305 causes the connecting bracket 306 to move vertically. The vertical movement of the connecting bracket 306 causes the sample chamber 204 to sink into the solution pool 203 or move upward into the air outlet assembly 202. This allows the sample to select solution pools 203 with different components during periodic immersion, and facilitates the completion of periodic immersion work by the main body of the equipment 1.

[0037] Refer to the instruction manual appendix Figure 1-4Multiple solution pools 203 are sealed at their bottom ends with inlet and outlet pipes, which also pass through the main body 1 and connect to an external container. This allows for the storage of solutions with different components in the multiple solution pools 203, enabling the use of various solution pools 203 during sample immersion. A ventilation valve is installed on the ventilation duct 201, which is connected to the air outlet assembly 202, facilitating air circulation within the main body 1. The air outlet assembly 202 has multiple ventilation pipes on its surface and includes a heating wire module and a humidification module inside. This allows the air outlet assembly 202 to humidify or heat the airflow inside the ventilation duct 201, thereby better simulating the immersion environment of the sample.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
