Description

A material water resistance testing device Technical Field

[0001] This utility model relates to the field of water resistance testing, and in particular to a device for testing the water resistance of materials. Background Technology

[0002] Material water resistance testing equipment is a specialized device used to evaluate the ability of materials to withstand contact with water or humid environments. The water resistance of materials such as coatings and waterproofing materials is a crucial indicator for assessing their long-term performance. Traditional testing methods, such as immersion methods, suffer from problems such as long testing cycles and high data subjectivity. Industries such as construction and automotive require rapid and quantitative assessments of material water resistance.

[0003] A search of existing technologies revealed an "apparatus for testing the water resistance of paint films," with publication number "CN218271878U." This apparatus uses both immersion and dripping methods to test the water resistance of paint films. This simultaneous water resistance testing method can quickly help technicians screen raw materials, thereby improving the efficiency of coating research and development. However, this apparatus is difficult to simulate dynamic water environments such as rainwater erosion, which leads to errors in the actual use of the apparatus and the test results, affecting the accuracy of material testing.

[0004] Therefore, a material water resistance testing device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a material water resistance testing device to solve the above-mentioned problems, thereby improving the difficulty in simulating dynamic water environments such as rainwater erosion, which leads to errors in the actual use of the device and affects the accuracy of material testing.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a material water resistance testing device, comprising: a simulation chamber, a liquid storage tank fixedly connected to one side of the simulation chamber, the inner bottom wall of the simulation chamber being inclined, a through pipe fixedly connected to the inner wall of the simulation chamber, a rotating pipe rotatably connected to the inner wall of the through pipe, an operating handle fixedly connected to one end of the rotating pipe, and a rectangular hole opened on the surface of the through pipe, the rectangular hole penetrating into the interior of the rotating pipe; a simulation mechanism, the simulation mechanism being installed inside the liquid storage tank, the surface of the simulation mechanism extending to the upper end of the simulation chamber; wherein, the simulation mechanism includes a water pump installed on the inner bottom wall of the liquid storage tank, a flushing assembly connected to the upper end of the water pump, the flushing assembly being installed at the upper end of the simulation chamber, and a heating assembly installed inside the liquid storage tank.

[0007] Preferably, the flushing assembly includes two sealing seats fixedly connected to the upper end of the simulation tank. A flow equalization pipe is rotatably connected to the inner wall of the two sealing seats. Multiple guide pipes are fixedly connected to the lower end of the flow equalization pipe. A corrugated pipe is connected to the inner wall of one end of the sealing seat and is installed at the upper end of the water pump. Rotating the flow equalization pipe adjusts the impact angle of the guide pipes against the bottom wall of the simulation tank, simulating the impact of water flow at different angles in the operating environment.

[0008] Preferably, the heating assembly includes a temperature-conducting plate fixedly connected to the bottom wall of the liquid storage tank. Multiple heating blocks are connected to the inner wall of the temperature-conducting plate, and multiple first and second heat-conducting fins are fixedly connected to both sides of the temperature-conducting plate. The heating blocks heat the liquid inside the liquid storage tank, mimicking the temperature differences of the liquid in different seasons.

[0009] Preferably, a positioning block is fixedly connected to the surface of the flow equalization pipe, and the surface of the positioning block has multiple circular holes.

[0010] Preferably, a sleeve is fixedly connected to the upper end of the other end of the sealing seat, and a positioning pin is slidably connected to the inner wall of the sleeve, with one end of the positioning pin penetrating into the interior of the positioning block.

[0011] Preferably, a spring is fixedly connected to the surface of the positioning pin, and the other end of the spring is fixedly connected to the inner wall of the sleeve. The spring causes the positioning pin to move towards the circular hole of the positioning block under normal conditions, thus creating a positioning effect by adjusting the rotation angle of the positioning block relative to the flow equalization tube.

[0012] Preferably, the first and second heat-conducting sheets are staggered, with the lower inclined surface of the first heat-conducting sheet forming an acute angle with the inner bottom wall of the liquid storage tank. The first and second heat-conducting sheets increase the contact area with the liquid, improving the heat conduction and heating effect. Under the action of the second heat-conducting sheet, the flowing water is guided.

[0013] The beneficial effects of this utility model are:

[0014] 1. The above-mentioned material water resistance testing device, under the action of the flushing component, pumps the liquid inside the storage tank into the bellows through a water pump. Through the sealing of the sealing seat, the water flow is introduced into the flow equalization pipe and guided by the guide pipe to simulate the bottom wall of the tank for flushing. This makes the positioning block's rotation angle relative to the flow equalization pipe form a positioning effect, simulating the state of water flow impact at different angles in the use environment, reducing the error between actual use and the test effect, and ensuring the accuracy of material testing.

[0015] 2. By setting up a heating component, the liquid inside the storage tank can be auxiliaryly heated under the action of the heating component. The device uses a temperature-conducting plate to assist in the temperature conduction of the water flow, which improves the temperature conduction and heating effect. The heating block heats the liquid inside the storage tank, simulating the temperature difference of the liquid in different seasons. However, it is difficult to simulate dynamic water environments such as rain erosion, which causes errors in the actual use of the device and the detection effect, affecting the accuracy of material testing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In specific implementation: As shown in Figures 1-5, a material water resistance testing device includes: a simulation chamber 1, a liquid storage tank 11 fixedly connected to one side of the simulation chamber 1, the inner bottom wall of the simulation chamber 1 is inclined, a through pipe 2 fixedly connected to the inner wall of the simulation chamber 1, a rotating pipe 22 rotatably connected to the inner wall of the through pipe 2, an operating handle 23 fixedly connected to one end of the rotating pipe 22, a rectangular hole 21 opened on the surface of the through pipe 2, the rectangular hole 21 penetrating into the interior of the rotating pipe 22; a simulation mechanism 3, the simulation mechanism 3 is installed inside the liquid storage tank 11, the surface of the simulation mechanism 3 extends to the upper end of the simulation chamber 1; wherein, the simulation mechanism 3 includes a water pump 33 installed on the inner bottom wall of the liquid storage tank 11, a flushing component 31 connected to the upper end of the water pump 33, the flushing component 31 is installed at the upper end of the simulation chamber 1, and a heating component 32 is installed inside the liquid storage tank 11;

[0024] As shown in Figures 1, 2 and 4, the flushing assembly 31 includes two sealing seats 311 fixedly connected to the upper end of the simulation box 1. The inner walls of the two sealing seats 311 are rotatably connected to a flow equalization pipe 312. The lower end of the flow equalization pipe 312 is fixedly connected to multiple guide pipes 313. The inner wall of one end of the sealing seat 311 is connected to a bellows pipe 314. The bellows pipe 314 is installed at the upper end of the water pump 33. The surface of the flow equalization pipe 312 is fixedly connected to a positioning block 315. The surface of the positioning block 315 is provided with multiple round holes.

[0025] The upper end of the other sealing seat 311 is fixedly connected to a sleeve 316, and a positioning pin 317 is slidably connected to the inner wall of the sleeve 316. One end of the positioning pin 317 penetrates into the interior of the positioning block 315, and a spring 318 is fixedly connected to the surface of the positioning pin 317. The other end of the spring 318 is fixedly connected to the inner wall of the sleeve 316.

[0026] The device adjusts the impact angle of the guide pipe 313 on the inner bottom wall of the simulation tank 1 by rotating the flow equalization pipe 312, simulating the state of water flow impact at different angles in the usage environment. The device pumps the liquid inside the storage tank 11 into the bellows 314 through the water pump 33, and the water flow is guided into the flow equalization pipe 312 through the sealing seat 311. The water flow is then guided to the inner bottom wall of the simulation tank 1 for flushing through the guide pipe 313. The spring 318 causes the positioning pin 317 to move towards the circular hole of the positioning block 315 under normal conditions, so that the rotation angle of the positioning block 315 relative to the flow equalization pipe 312 forms a positioning effect.

[0027] As shown in Figures 1, 2 and 5, the heating assembly 32 includes a temperature-conducting plate 321 fixedly connected to the inner bottom wall of the liquid storage tank 11. Multiple heating blocks 322 are connected to the inner wall of the temperature-conducting plate 321. Multiple first heat-conducting sheets 323 and second heat-conducting sheets 324 are fixedly connected to both sides of the temperature-conducting plate 321. The first heat-conducting sheets 323 and second heat-conducting sheets 324 are staggered. The lower end slope of the first heat-conducting sheet 323 forms an acute angle with the inner bottom wall of the liquid storage tank 11.

[0028] The device heats the liquid inside the storage tank 11 using a heating block 322 to simulate the temperature difference of the liquid in different seasons. At this time, the temperature-conducting plate 321 assists in heating the water flow. The first heat-conducting plate 323 and the second heat-conducting plate 324 increase the contact surface with the liquid, improving the heating effect. Meanwhile, the water pump 33 guides the water flow, causing the liquid inside the storage tank 11 to flow. Under the action of the second heat-conducting plate 324, the flowing water flow is guided.

[0029] In use, the flow equalization pipe 312 is rotated to adjust the impact angle of the guide pipe 313 on the inner bottom wall of the simulation box 1. The water pump 33 pumps the liquid inside the storage tank 11 into the bellows 314. Through the sealing of the sealing seat 311, the water flow is introduced into the flow equalization pipe 312 and guided to the inner bottom wall of the simulation box 1 by the guide pipe 313 to flush it. The spring 318 and the positioning pin 317 move towards the circular hole of the positioning block 315 under normal conditions. The positioning block 315 positions the flow equalization pipe 312 according to its rotation angle. The heating block 322 heats the liquid inside the storage tank 11. The first heat-conducting plate 323 and the second heat-conducting plate 324 increase the contact surface with the liquid, thereby improving the heat conduction and heating effect.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
