[0029] Embodiment
[0030] Refer to Figures 1 - 3 , a sand and dust environment test chamber disclosed by the present utility model, which includes:
[0031] An air inlet section, a sand spraying section, an experimental chamber 100, a sand cleaning section 800, and a discharge section 900. The tail of the air inlet section is connected to the head of the sand spraying section, the tail of the sand spraying section is connected to the head of the experimental chamber 100, the tail of the experimental chamber 100 is connected to the head of the sand cleaning section 800, and the tail of the sand cleaning section 800 is connected to the discharge section 900. Among them, the head of the air inlet section is an air inlet 200, and the air flow direction is from the head of all components to the tail; a sand spraying device 700 is arranged at the top of the sand spraying section; a spray head 801 is arranged at the top inside the head of the sand cleaning section 800, and the spray head 801 is used for spraying water. The components in the present utility model are arranged on the ground through a bracket 1000.
[0032] Specifically, the air flow direction enters the test chamber through the air inlet section, and then the sand and dust are brought into the experimental chamber 100 through the sand spraying section to simulate a sand and dust weather, and then reach the sand cleaning section 800 where the sand and dust are washed away by water flow, and then the air and sewage are discharged in the discharge section 900.
[0033] Specifically, through the sandblasting device 700 at the top of the sandblasting section, the equipment can effectively simulate a sandstorm weather, enabling the observation of the impact of sandstorm weather on the target object (which may be a certain device, material or system) inside the experimental chamber 100. This is of great significance for studying the equipment performance, durability and protective measures under sandstorm weather. After simulating the sandstorm weather, in the sand cleaning section 800, the sand is washed away by spraying water through the nozzle 801. This design also allows researchers to test the influence of different water spraying methods, water pressures and flow rates on the sand cleaning effect, so as to optimize the sand cleaning plan. From the air inlet section to the discharge section 900, the overall equipment structure is designed compactly, and the connection between components is smooth, making the operation simple and efficient. In addition, this design helps to reduce the floor area of the equipment, facilitating the simulation and testing of sandstorm weather in the laboratory or on-site. Since the sand and water spraying processes are carried out inside the closed equipment, this greatly reduces the risk of operators contacting harmful substances and improves the safety of the experiment.
[0034] Generally, a vehicle 103 is placed on the test bench in the experimental chamber 100. According to the needs, the driving performance of the vehicle 103 in a sand environment is evaluated by measuring the performance parameters such as acceleration, braking and handling of the vehicle 103. The wear conditions of the appearance and interior of the vehicle 103 are inspected to evaluate the erosion degree of the sand on the surface of the vehicle 103. The key components such as the engine, chassis and electrical system of the vehicle 103 are inspected to evaluate the influence of the sand on these components. By checking the sealing and filtering performance of the vehicle 103, the protection ability of the vehicle 103 in a sand environment is evaluated.
[0035] It is further set that: the air inlet section includes a fan 300, a straight flow section 400, and a static pressure section 500. The head of the straight flow section 400 is connected to the fan 300, and the tail of the straight flow section 400 is connected to the static pressure section 500; a flow stabilizing plate is arranged inside the straight flow section 400 to eliminate gas turbulence.
[0036] Specifically, the fan 300 provides a stable air flow supply for the entire system, ensuring that the air inlet section can continuously and stably convey air to subsequent components. By adjusting the rotation speed of the fan 300, the speed of the air flow can be precisely controlled, thereby simulating sandstorm weather conditions at different wind speeds. The flow stabilizer plates inside the straight flow section 400 can effectively eliminate air turbulence, making the air flow more uniform and stable before entering the sandblasting section. Eliminating air turbulence helps reduce experimental errors and improve the accuracy and reliability of sandstorm weather simulation. The smooth air flow also reduces the impact and wear on subsequent components (such as the sandblasting section and the experimental chamber 100), thereby extending the service life of the equipment. The static pressure section 500, through its structural design, enables the air flow to reach a stable pressure distribution state before entering the sandblasting section. The stable pressure distribution helps the sandblasting device 700 spray sand more evenly, making the sand distribution in the experimental chamber 100 more uniform and improving the simulation effect. The introduction of components such as the fan 300, the straight flow section 400, the static pressure section 500, and the flow stabilizer plates not only enhances the stability and reliability of the equipment but also improves the accuracy and reliability of sandstorm weather simulation. This makes the equipment have higher application value and technical advantages in the field of sandstorm weather-related research. At the same time, the design of these components also reflects the refined consideration of air flow control and treatment.
[0037] It is further set that: docking bayonet sockets 101 are provided at both ends of the experimental chamber 100, and the experimental chamber 100 is detachably connected to the sandblasting section and the sand cleaning section 800 through the docking bayonet sockets 101; an experimental table 102 is arranged inside the experimental chamber 100. The detachable experimental chamber 100 facilitates the replacement of experimental objects.
[0038] Specifically, the experimental chamber 100 is detachably connected to the sandblasting section and the sand cleaning section 800 through the docking bayonet 101. This design makes the assembly and disassembly of the equipment fast and simple. The detachable connection method makes the whole equipment show the characteristics of modular design, which is convenient for the transportation, storage and later maintenance of the equipment. Since the experimental chamber 100 can be easily disassembled, researchers can replace or adjust the experimental chamber 100 according to experimental needs, increasing the flexibility of the equipment. The experimental bench 102 provides stable fixation and support for the test objects placed in the experimental chamber 100, ensuring stability and safety during the test process. The design of the experimental bench 102 enables researchers to conveniently carry out experimental operations, such as placing, adjusting or observing the test objects. The configurability of the experimental bench 102 enables the equipment to adapt to different types of experiments. Whether it is testing the durability and performance of the equipment or evaluating the effectiveness of protective measures, it can be carried out on the experimental bench 102. The design of the docking bayonet 101 of the experimental chamber 100 and the experimental bench 102 not only improves the assembly, disassembly and transportation efficiency of the equipment, but also provides a stable and safe experimental operation platform for researchers, further enhancing the technical effect and practicality of the equipment. This design makes the equipment have higher application value and technical advantages in the field of research related to sandstorm weather.
[0039] It is further set that: a ramp is provided at the bottom of the sand cleaning section 800, and the side of the ramp close to the tail of the sand cleaning section 800 is lower than the side close to the head of the sand cleaning section 800.
[0040] Specifically, the setting of the ramp ensures that the water flow can flow downward along the slope when flowing through the sand cleaning section 800, thereby effectively flushing and removing the sand and dust adhering to the test chamber. This top-down water flow flushing method can efficiently remove sand and dust and improve the cleaning effect. Without the ramp, the water flow may accumulate in a certain part of the sand cleaning section 800 and cannot be discharged smoothly. The setting of the ramp avoids this situation and ensures that the water flow can quickly flow to the discharge section 900, preventing the accumulation and retention of the water flow. The design of the ramp optimizes the path of the water flow, enabling the water flow to cover the entire sand cleaning section 800 more evenly, reducing the dead corners of the water flow, and improving the uniformity and thoroughness of cleaning. Since the ramp can efficiently remove sand and dust, reducing the accumulation of sand and dust inside the equipment, the risk of equipment damage due to sand and dust accumulation is reduced. This helps to extend the service life of the equipment and reduce maintenance costs.
[0041] It is further set that: the tail of the sand cleaning section 800 is detachably connected to the discharge section 900 through the docking bayonet 101. Through the detachable connection, the discharge section can be disassembled at any time to clean the sand and dust in the discharge section. Since the discharge section 900 can be disassembled separately, researchers do not need to carry out large-scale disassembly of the entire equipment to clean and maintain the discharge section 900. This greatly simplifies the maintenance process and improves the maintenance efficiency.
[0042] Refer to Figure 4 , Figure 4 FIG. is a cross-sectional view of the sandblasting device 700. The sandblasting device 700 includes a sand storage box 701, a sandblasting port 702, and a flow blocking net 703. The flow blocking net 703 is disposed between the sand storage box 701 and the sandblasting port 702. Among them, the sand storage box 701 and the flow blocking net 703 are located at the top outside the sandblasting section, and the sandblasting port 702 is located at the top inside the sandblasting section.
[0043] Specifically, for sand storage and supply: The sand storage box 701 serves as a storage container for sand, ensuring a stable supply of sand during the experiment. Its design at the top outside the sandblasting section facilitates the addition and replacement of sand, and at the same time reduces the risk of sand leakage. The flow blocking net 703 is disposed between the sand storage box 701 and the sandblasting port 702 and plays a key role. It can block larger particles or impurities in the sand, ensuring that only sand particles meeting the requirements can enter the sandblasting port 702. In this way, the sand ejected from the sandblasting port 702 is more uniform, which helps to improve the accuracy of the experimental results. The sandblasting port 702 is located at the top inside the sandblasting section. This design enables the sand to be directly and efficiently sprayed into the experimental chamber 100, reducing the loss and dispersion of sand during the transmission process. At the same time, the top sandblasting method is also closer to the state of natural sand weather, improving the authenticity of the simulation. Since the sand storage box 701 and the flow blocking net 703 are located at the top outside the sandblasting section, researchers can conveniently maintain, clean, and replace them. This reduces the maintenance cost of the equipment, improves the reliability and service life of the equipment.
[0044] Refer to Figure 5 , Figure 5 FIG. is a cross-sectional view of the discharge section 900. The discharge section 900 includes an exhaust section 910 and a drainage section 920. The exhaust section 910 is detachably connected to the top of the drainage section 920. The exhaust section 910 faces upward to discharge high-speed air, and the drainage section 920 faces downward to allow water flow to carry away sand.
[0045] Specifically, by designing the exhaust section 910 at the top of the drainage section 920, the device achieves effective separation of wind and dust. The exhaust section 910 faces upward and can discharge the high-speed wind processed by the sand cleaning section 800, ensuring that the wind does not carry dust back into the experimental environment. The drainage section 920 faces downward and uses water flow to carry away the remaining dust, thus achieving complete separation of wind and dust and improving the cleaning efficiency of the device. The detachable connection design of the exhaust section 910 and the drainage section 920 enables researchers to quickly disassemble and assemble as needed. This not only facilitates the transportation and storage of the device but also allows for separate operation of the exhaust section 910 or the drainage section 920 during cleaning and maintenance, greatly improving the convenience and efficiency of maintenance. The separation design of the exhaust section 910 and the drainage section 920 makes the device structure more compact and reasonable, optimizing space utilization. At the same time, this design also facilitates flexible configuration and adjustment of the discharge section 900 by researchers according to experimental requirements.
[0046] It is further set that: a first filter screen 911 is provided at the bottom of the exhaust section 910; an air outlet 913 is fixedly connected to the top of the exhaust section 910; a second filter screen 912 is detachably connected to the inner side of the air outlet 913. The two-layer filter screen can reduce the probability of dust being blown out and effectively prevent dust from polluting the external environment.
[0047] Specifically, the first filter screen 911 and the second filter screen 912 together constitute a double filtration system, which can effectively block and filter out the dust particles carried by the wind. This double filtration mechanism greatly reduces the probability of dust being blown out of the exhaust section 910 and polluting the external environment, improving the environmental protection performance of the device. The design of the two-layer filter screen increases the filtration area and filtration level, thereby improving the filtration efficiency. The first filter screen 911 mainly intercepts larger dust particles, while the second filter screen 912 can further filter out smaller particles to ensure that the discharged wind is cleaner. The second filter screen 912 is detachably connected, which enables researchers to conveniently clean and replace it. When the filter screen is full of dust, it only needs to be disassembled for cleaning or replaced with a new filter screen to restore its filtration effect, ensuring the continuous and stable operation of the device.
[0048] It is further set that: a drainage pipe 922 is connected to the bottom of the drainage section 920; a sand filter screen 921 is provided at the bottom of the drainage section 920, and the sand filter screen 921 is above the drainage pipe 922.
[0049] Specifically, the drainage pipe 922 connected to the bottom of the drainage section 920 ensures the smooth discharge of water flow, prevents water accumulation inside the experimental chamber 100, and maintains the stability of the experimental environment. A sand filter net 921 is arranged above the drainage pipe 922, which can effectively block the dust particles carried in the water flow and prevent them from entering the drainage pipe 922, causing pipe blockage or wear. The existence of the sand filter net 921 not only extends the service life of the drainage pipe 922, but also protects the normal operation of the entire drainage system, reducing the failures and maintenance costs caused by dust blockage. Through the filtering effect of the sand filter net 921, most of the dust is intercepted within the drainage section 920, which helps to reduce the burden of subsequent cleaning work and improve the cleaning efficiency. The collected dust can also be reused.
[0050] It is further set as follows: the air inlet section and the sandblasting section are connected by a bent pipe; a flow guide plate 600 is arranged inside the bent pipe.
[0051] Specifically, the function of the flow guide plate 600 inside the bent pipe is to guide and optimize the flow direction of the air flow. It ensures that the air flow in the air inlet section can smoothly and efficiently enter the sandblasting section, reducing the turbulence and energy loss of the air flow at the bend. This design helps to improve the stability and uniformity of the air flow during the sandblasting process, thereby enhancing the accuracy of the experimental results. The combined design of the bent pipe and the flow guide plate 600 helps to reduce the noise generated by the air flow during transmission. The flow guide plate 600 can reduce the collision and friction of the air flow inside the pipe, thereby reducing the generation of noise. This is of positive significance for maintaining the quietness and stability of the experimental environment and protecting the hearing health of the experimental personnel. The design of connecting the air inlet section and the sandblasting section by a bent pipe and arranging a flow guide plate 600 inside the pipe optimizes the air flow direction, reduces the air flow noise, enhances the structural stability, and facilitates the installation and maintenance work. These technical effects together improve the performance and practicality of the sand and dust weather simulation equipment.
[0052] The working principle and beneficial effects of the present utility model are as follows:
[0053] In the present utility model, the designs of the sand cleaning section 800, the sand spraying device 700, the discharging section 900, and the air inlet section all play crucial roles. The ramp provided at the bottom of the sand cleaning section 800 enables the water flow to flow down smoothly, effectively removing the dust in the experimental chamber 100, preventing the accumulation of dust, and improving the cleaning efficiency. The sand spraying device 700, through the combination of the sand storage box 701, the sand spraying port 702, and the flow blocking net 703, ensures the uniform spraying of dust, simulating a real sandstorm weather. The design of the discharging section 900 focuses on the separation and discharge of sand and wind. The separation of the exhaust section 910 and the drainage section 920, as well as the use of two layers of filter meshes, effectively reduces the discharge of dust and protects the external environment. The design of the filter sand net 921 at the bottom of the drainage section 920 avoids the blockage of the drainage pipe 922 and extends the service life of the equipment. The air inlet section and the sand spraying section are connected by a curved pipe, and a flow guiding plate 600 is provided, optimizing the air flow, improving the stability and accuracy of the experiment. At the same time, this design also reduces the air flow noise, enhances the structural stability of the equipment, and makes the installation and maintenance more convenient. These design details not only improve the performance of the sandstorm weather simulation equipment but also enhance its usability and reliability. Together, they constitute an efficient, stable, and environmentally friendly experimental system, providing strong technical support for research related to sandstorm weather.
