Description

Technical Field

[0001] The utility model relates to an ice water impact test box. Background Art

[0002] The high and low temperature chamber is a powerful device that is mainly used to simulate various complex temperature conditions to meet the needs of different fields such as industry, scientific research and laboratories. The research and development and application of this equipment is undoubtedly an important achievement of modern scientific and technological development. Its background technology covers many key areas, including temperature control, selection and application of insulation materials, efficient heating and cooling systems, etc.

[0003] First of all, the high and low temperature chamber has shown extremely high accuracy in temperature control.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] Example

[0028] See also Figure 1-4 As shown, an ice water impact test box includes a test box body 1 and a machine room 2, the test box body 1 includes an upper high temperature zone and a lower low temperature zone, an air duct assembly 6 is installed on the rear side of the upper high temperature zone, and an inlet and outlet water pipe is installed in the lower low temperature zone. A movable basket 7 that can carry products and move back and forth between the upper high temperature zone and the lower low temperature zone is provided in the test box body 1, a four-link lifting assembly 4 is provided outside the test box body 1, a counterweight assembly 5 is provided outside the test box body 1, protective sheet metals 3 are provided on the left and right sides of the test box body 1, and a circulating cooling water system 8 is provided in the machine room 2.

[0029] The test chamber can achieve rapid switching between high temperature and low temperature in a short time, so that hot and cold shock tests can be carried out quickly and the test efficiency is improved; an upper high temperature zone and a lower low temperature zone are arranged in the test chamber body 1, and precise temperature control is achieved through a circulating cooling water system 8, which can meet the testing requirements of different products.

[0030] A movable basket 7 is provided inside the test box body 1, which can carry products and move back and forth between the high temperature zone and the low temperature zone, so that the products can be subjected to hot and cold shock tests under different temperature environments to ensure that the test results are accurate and reliable; a four-link lifting component 4 is provided outside the test box body 1, which can lift and lower the entire test box as needed, making it convenient for operators to load and take out products.

[0031] A counterweight assembly 5 is installed on the outside of the test box body 1 to improve the stability of the test box; at the same time, protective sheet metals 3 are installed on the left and right sides to protect the test box from the external environment.

[0032] The principle of this scheme is to achieve rapid hot and cold shock to the product through temperature control of the upper high temperature zone and the lower low temperature zone, and the operation of the circulating cooling water system 8. When a hot and cold shock test is required, the circulating cooling water system 8 will adjust the temperature of the upper high temperature zone and the lower low temperature zone to the required temperature range, and then place the product in the movable basket 7, and the basket will run back and forth between the high temperature zone and the low temperature zone to perform hot and cold shock tests on the product under different temperature environments. Through precise temperature control and the flexible design of the movable basket 7, the temperature changes in the real environment can be simulated to evaluate the performance and reliability of the product under different temperature conditions.

[0033] The wind duct assembly 6 has fan blades and wind ducts installed inside, and each fan blade is matched with a wind duct and fixed side by side on the wind duct assembly 6. The surfaces of the parts inside the wind duct assembly 6 are coated with a Teflon layer.

[0034] The design of the air duct assembly 6 allows the air to fully contact the surface of the heating or cooling element, thereby improving the heat transfer efficiency. The rotation of the fan blades can help the air flow and increase the heat dissipation or heat absorption capacity of the product; the existence of the air duct can ensure that the air is evenly distributed in the air duct assembly 6 to avoid uneven temperatures. This is very important for the hot and cold shock test of the product in the test chamber, because it can ensure that the product is subjected to a uniform temperature throughout the test process.

[0035] Teflon is a material with excellent heat resistance and corrosion resistance, which can effectively reduce the friction resistance between the internal parts of the air duct assembly 6 and the air. In addition, the Teflon layer can also provide certain protection and reduce the damage of the parts to external factors.

[0036] When the air duct assembly 6 is started, the fan blades start to rotate, generating airflow. The air is guided to the designated area through the air duct to exchange heat with the heating or cooling element. The rotation of the fan blades and the design of the air duct ensure that the air can cover the surface of each element, thereby achieving efficient heat transfer. At the same time, the coating of the Teflon layer reduces the friction between the parts and the air, thereby improving the operating efficiency of the system.

[0037] The quadruple lifting assembly 4 includes a motor transmission reversing assembly installed on the top of the test box, and lead screws installed on the left and right sides of the test box.

[0038] The quadruple lifting assembly 4 makes the lifting and lowering operation of the test chamber more convenient. Through the combination of the motor drive reversing assembly and the lead screw, the lifting and lowering control of the entire test chamber can be realized without manual operation, which improves the convenience of operation; the lead screw in this solution provides stable support to ensure that the test chamber remains balanced and stable during the rising and falling process. This is very important for the protection of products in the test chamber and the accuracy of test results; the motor drive reversing assembly can accurately control the lifting height of the test chamber. By adjusting the rotation direction and speed of the motor, the test chamber can be accurately lifted and lowered to meet the needs of different test scenarios.

[0039] When lifting and lowering operations are required, the motor transmission reversing assembly drives the movement of the lead screw through the rotation of the motor. The lead screw is fixed to the left and right sides of the test box, and the nut is installed on the top of the test box. When the motor rotates, the threads of the lead screw interact with the threads of the nut, resulting in the lifting and lowering movement of the test box.

[0040] The test chamber can be adjusted in height by changing the direction and speed of the motor. The combination of the motor drive reversing assembly and the lead screw provides stable support and precise control, ensuring that the test chamber can be raised and lowered smoothly.

[0041] The movable lifting basket 7 is provided with lifting ears on the left and right sides, and the lifting ears are arranged on the screw rod outside the test box body 1. The top and bottom of the movable lifting basket 7 are covered with TA2 plates.

The bottom of the movable lifting basket 7 is provided with a movable overflow port. The bottom of the movable lifting basket 7 is provided with a rectangular tube for carrying products, and the rectangular tube is provided with fixing holes for fixing products.

[0042] The movable basket 7 can be lifted and moved conveniently by means of the lifting ears arranged on the left and right sides. In this way, the operator can easily move the test box to the required position, which improves the flexibility and efficiency of the operation; the top and bottom of the movable basket 7 are covered with TA2 plates, which increases the stability and strength of the overall structure. The TA2 plates have good corrosion resistance and can protect the movable basket 7 from damage by external factors.

[0043] The top of the movable basket 7 is fixed with a power line and a water pipe that move up and down with the movable basket 7. In this way, the movable basket 7 can be easily provided with power and water sources, such as electricity and water supply pipes, to meet the electrical and water treatment requirements inside the test chamber; the bottom of the movable basket 7 is equipped with a movable overflow port for discharging overflowed water or liquid. This can ensure that the humidity and level inside the test chamber are kept within a suitable range to prevent excessive water accumulation or leakage in the test chamber; the bottom of the movable basket 7 is equipped with a rectangular tube that carries the product and is provided with fixing holes. This means that the product to be tested can be safely fixed inside the movable basket 7 to prevent movement or damage during transportation and testing.

[0044] By adjusting the position of the lifting ears and the screw rod, the lifting operation of the movable basket 7 can be realized. At the same time, the top and bottom of the movable basket 7 are covered with TA2 plates, which make it have better structural stability and corrosion resistance; the power line and water pipe are fixed on the top of the movable basket 7. As the basket moves up and down, they can be connected to the corresponding power and water sources to provide the required power and water supply for the test box.

[0045] The movable overflow port is located at the bottom of the movable basket 7 and is used to discharge overflow water or liquid generated during the test to maintain the humidity and level inside the test box. The rectangular tube carrying the product is located at the bottom of the movable basket 7 and is provided with fixing holes for safely fixing the product to be tested.

A limit buffer block is installed under the counterweight assembly 5, and the limit block is equipped with a PU buffer block. The pipeline of the circulating cooling water system 8 is spliced ​​by PPR hot-melt splicing.

[0047] The counterweight assembly 5 is connected to the lifting lugs by a steel wire rope and moves with the movable lifting basket 7. This has the advantage of balancing the weight of the test box, reducing the burden on the operator during lifting and moving, and increasing the stability and safety of the entire system; the counterweight assembly 5 is equipped with V-shaped wheels on the upper and lower parts, which can provide stable rolling support during movement, reduce friction, and make the test box move more smoothly.

[0048] A limit buffer block is installed under the counterweight block assembly 5, and a PU buffer block is installed on the block. When the test box drops to the bottom or collides with other objects, the limit buffer block and the PU buffer block can absorb the impact force, reduce the risk of damage, and protect the safety of the test box and surrounding equipment; the pipeline of the circulating cooling water system 8 adopts PPR hot melt splicing. PPR pipes have the characteristics of high temperature resistance, pressure resistance, corrosion resistance, etc., and are connected by hot melt splicing to ensure that the pipeline connection is firm and leak-free, providing a reliable circulating cooling water supply.

[0049] The counterweight assembly 5 is connected to the lifting ear through a steel wire rope, and the tension and length of the steel wire rope can be adjusted as needed to balance the weight of the test box; the V-shaped wheel is installed on the counterweight assembly 5, and through rolling support, the friction of the test box during movement is reduced, allowing it to move more smoothly.

[0050] The limit buffer block is located below the counterweight assembly 5. It can absorb the impact force generated when the test box drops to the bottom or collides with other objects, playing a role of buffer protection. The PU buffer block further increases the buffering effect; the pipeline of the circulating cooling water system 8 adopts PPR hot-melt splicing. After hot-melt connection, the PPR pipe forms a solid pipeline system that can withstand high temperature and pressure, and has good corrosion resistance, ensuring a stable supply of circulating cooling water.
