Technical Field
[0001] This utility model belongs to the technical field of large-scale environmental test chambers, and in particular relates to a temperature-zoned environmental test chamber separation device. Background Technology
[0002] An environmental test chamber is a closed indoor space used for testing large equipment. For example, when conducting vehicle dynamometer tests, it needs to be placed in an environmental test chamber to test the vehicle's performance by simulating various road conditions and environments. Temperature zoning is particularly important in test scenarios that require simulating different temperature environments and high and low temperature shock test scenarios.
[0003] In large environmental test chambers, especially when conducting high and low temperature tests, temperature shock tests, and experiments that require precise control of different temperature zones, traditional partition devices often fail to meet the requirements. Traditional partition methods may use simple partitions or door structures, but these structures often have problems such as poor sealing, complex operation, unstable structure, and insufficient flexibility. Summary of the Invention
[0004] The purpose of this invention is to address the problems existing in the prior art by providing a temperature-zoned environmental test chamber separation device.
[0005] To achieve the above objectives, the utility model employs the following technical solution: a temperature-zoned environmental test chamber partitioning device, the test chamber comprising a first chamber and a second chamber, a partition wall between the first chamber and the second chamber, an underground space inside the first chamber, a dynamometer mounted on the underground space, a mounting base on the partition wall, a first sliding door and a second sliding door on the inner side of the mounting base, a driving component between the first sliding door and the second sliding door and the mounting base respectively, a first airbag strip on the side of the first sliding door and the second sliding door near the partition wall respectively, an air pump communicating with the first airbag strip in the underground space; a pair of second airbag strips on the end of the first sliding door near the second sliding door, a connecting component between the two first airbag strips.
[0006] By adopting the above technical solutions, this patent significantly improves the sealing performance, automation level, structural stability, flexibility, and airflow management capabilities of the temperature zone environmental test chamber separation device through a series of innovative designs, providing a more reliable and efficient solution for high and low temperature testing, temperature shock testing, and other experiments on large equipment.
[0007] Optionally, the mounting base is concave, the length of the mounting base is greater than the distance between the two partition walls, and the bottom wall of the test chamber has a groove corresponding to the position of the mounting base.
[0008] By adopting the above technical solution, the concave mounting base provides a stable installation foundation for the first and second sliding doors, ensuring the stability and reliability of the sliding doors during the sliding process. The length of the mounting base is greater than the spacing of the partition walls, so that the sliding doors have enough space to slide when fully opened.
[0009] Optionally, the first sliding door has a groove at one end near the second sliding door, and the second sliding door has a protrusion that mates with the groove.
[0010] By adopting the above technical solution, the mating design of the groove and the protrusion achieves a tight fit between the first sliding door and the second sliding door, enhances the sealing between the sliding doors, prevents temperature leakage, and ensures the sealing performance of the partition device in the closed state.
[0011] Optionally, both the second sliding door and the first sliding door have a fixing groove on the side near the partition wall, and the first airbag strip is installed inside the fixing groove. Both the fixing groove and the first airbag strip are C-shaped.
[0012] By adopting the above technical solution, the design of the C-shaped fixing groove and the first airbag strip allows the airbag strip to fit tightly into the gap between the sliding door and the partition wall, the floor groove, and the mounting base, further enhancing the sealing performance of the partition device.
[0013] Optionally, the groove, the first sliding door, and the second sliding door are all provided with sealing strips.
[0014] By adopting the above technical solution, the design of the sealing strip further enhances the sealing performance of the partition device. In particular, when the sliding door is closed, the sealing strip can fit tightly between the sliding doors and on the contact surfaces between the sliding door and the mounting base, partition wall, and other components, effectively preventing temperature leakage and external interference.
[0015] Optionally, the driving component includes a pair of motors mounted on the mounting base, the output ends of the pair of motors are respectively fixedly connected to gears, the gears are located inside the mounting base, the first sliding door and the second sliding door are respectively mounted with racks that mesh with the gears, and the ends of the first sliding door and the second sliding door away from the racks are respectively mounted with fixed pulleys.
[0016] By adopting the above technical solution, the motor-driven gear and rack mechanism realizes the automated control of the first and second sliding doors, improving the accuracy and efficiency of operation. The design of the fixed pulley plays a guiding and supporting role, ensuring the stability and reliability of the sliding door during the sliding process.
[0017] Optionally, the exhaust end of the air pump is connected to an air supply pipe that penetrates and extends into the inside of the trench, and the air supply pipe is corrugated.
[0018] By adopting the above technical solution, the corrugated air supply pipe can flexibly adapt to the curved path in the trench, ensuring that the gas is smoothly transmitted to the airbag strip and providing stable inflation power for the airbag strip.
[0019] Optionally, the connector includes an insertion tube installed inside the groove, and the second sliding door is provided with a connecting tube for inserting the insertion tube into the connecting tube. The insertion tube and the connecting tube are respectively connected to the first airbag strip through connecting tubes.
[0020] By adopting the above technical solution, the design of the connector allows the first airbag strip on the second sliding door to be inflated by an air pump, thereby enhancing the overall sealing performance of the partition device.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. By installing a first airbag strip on the side of the first and second sliding doors near the partition wall and inflating it using an air pump in the underground space, the sealing performance of the partition device is effectively enhanced. Simultaneously, the design of the second airbag strip and connectors at the end of the first sliding door near the second sliding door further ensures the sealing effect between the two doors when closed, thus avoiding heat exchange between different temperature zones and improving the accuracy of experimental results. 2. Using a motor-driven gear and rack mechanism to control the opening and closing of the first and second sliding doors not only simplifies the operation process and reduces the labor intensity of operators but also improves the accuracy and efficiency of operation. 3. The mounting base is designed to be concave and its length is greater than the distance between the partition walls. A corresponding groove is also opened in the bottom wall of the test chamber. This design not only provides a stable foundation for the installation of the sliding doors but also makes the entire partition device more stable and reliable under pressure and temperature changes. Furthermore, the fixed pulley installed at the end of the sliding door away from the rack helps reduce friction and resistance during sliding, improving the stability and service life of the sliding doors.

[0032] like Figure 1As shown in Figure 6, the specific scheme of the embodiment is as follows: A temperature-zoned environmental test chamber partitioning device, wherein the test chamber 1 includes a first chamber 11 and a second chamber 12. The first chamber 11 and the second chamber 12 serve as the main spaces for environmental testing, used to accommodate the equipment or samples to be tested, and are respectively subjected to high and low temperature control. The test chamber 1 is equipped with a high and low temperature control system, which can ensure the temperature stability and accuracy of the experimental environment, improve the reliability of the test results, and is used to control the temperature of the first chamber 11 and the second chamber 12. The temperature adjustment range in the first chamber 11 and the second chamber 12 is -65℃ to +75℃. The temperature fluctuation is ≤1.0℃, and the internal net dimensions of the test chamber 1 are at least greater than 28000×6000×6000 (D depth×W width×H height, mm). The dimensions of the first chamber 11 are at least greater than 14000×6000×6000, and the dimensions of the second chamber 12 are at least greater than 14000×6000×6000. The first chamber 11 and the second chamber 12 can work independently or in combination. During high and low temperature testing, one of them is a high temperature chamber and the other is a low temperature chamber. Through the high and low temperature control system, the two chambers can simulate different temperature environments to meet different testing requirements.
[0033] A partition wall 15 is provided between the first chamber 11 and the second chamber 12 to achieve physical separation and provide an independent testing environment for the two chambers. An underground space 13 is provided inside the first chamber 11. The distance between the two partition walls 15 is the same as the width of the underground space 13. A dynamometer 14 is provided on the underground space 13.
[0034] The partition wall 15 is provided with a mounting base 2, which provides a stable foundation for the installation of the first sliding door 3 and the second sliding door 4, ensuring the stability and reliability of the sliding doors during the sliding process. The mounting base 2 is concave, and its length is greater than the distance between the two partition walls 15. The bottom wall of the test chamber 1 has a groove 101 corresponding to the position of the mounting base 2. The first sliding door 3 and the second sliding door 4 are provided on the inner side of the mounting base 2. The first sliding door 3 and the second sliding door 4 are made of composite material, which has the advantages of high strength, light weight, and resistance to high and low temperatures. The first sliding door 3 and the second sliding door 4 open or close the passage between the first chamber 11 and the second chamber 12 by sliding, realizing temperature zone control and flexibly adjusting the separation state between the two chambers to meet different testing requirements. The first sliding door 3 has a groove 301 at one end near the second sliding door 4, and the second sliding door 4 has a protrusion that mates with the groove 301. The mating design of the groove 301 and the protrusion achieves a tight fit between the first sliding door 3 and the second sliding door 4, enhancing the sealing between the sliding doors and preventing temperature leakage. The second sliding door 4 and the first sliding door 3 both have fixing grooves 401 on the side near the partition wall 15. The groove 301, the first sliding door 3 and the second sliding door 4 are all equipped with sealing strips. There are two sealing strips on the inner side of the groove 301, located on both sides of the protrusion. The sealing strips on the first sliding door 3 and the second sliding door 4 are located on the side walls at the upper and lower ends, respectively. The design of the sealing strips further enhances the sealing of the partition device and ensures the stability of the test environment.
[0035] A driving component 5 is provided between the first sliding door 3 and the second sliding door 4 and the mounting base 2. The driving component 5 includes a pair of motors 51 mounted on the mounting base 2. The output ends of the pair of motors 51 are respectively fixedly connected to gears 52. The gears 52 are located inside the mounting base 2. The first sliding door 3 and the second sliding door 4 are respectively equipped with racks 53 that mesh with the gears 52. The ends of the first sliding door 3 and the second sliding door 4 away from the racks 53 are respectively equipped with fixed pulleys 54. By driving the gear 52 and rack 53 mechanism through the motors 51, the automatic control of the first sliding door 3 and the second sliding door 4 is realized, which improves the accuracy and efficiency of operation.
[0036] The first sliding door 3 and the second sliding door 4 are respectively provided with a first airbag strip 6 on the side near the partition wall 15. The first airbag strip 6 is installed inside the fixing groove 401. Both the fixing groove 401 and the first airbag strip 6 are C-shaped. The C-shaped design can seal the gaps between the first sliding door 3 and the second sliding door 4 and the mounting groove, the ground groove 101, and the partition wall 15, improving the sealing performance of the partition device and ensuring the independence of the test environment. An air pump 7 connected to the first airbag strip 6 is provided in the underground space 13. The exhaust end of the air pump 7 is connected to an air supply pipe 701 that penetrates and extends to the inside of the ground groove 101. The air supply pipe 701 is corrugated. The corrugated design of the air supply pipe 701 can flexibly adapt to the curved path in the ground groove 101, ensuring that the gas is smoothly transmitted to the airbag strip. The air pump 7 and the air supply pipe 701 can provide inflation power for the first airbag strip 6, ensuring the inflation effect and stability of the airbag strip, and further enhancing the sealing performance of the partition device.
[0037] A pair of second airbag strips 8 are provided at one end of the first sliding door 3 near the second sliding door 4. The first airbag strip 6, the second airbag strip 8 and the sealing gasket 402 are all made of high temperature resistant material. A connector 9 is provided between the two first airbag strips 6. The connector 9 includes an insertion tube 91 installed on the inner side of the groove 301. The second sliding door 4 is provided with a connecting pipe 92 for the insertion tube 91 to be inserted. The insertion tube 91 and the connecting pipe 92 are respectively connected to the first airbag strips 6 through connecting pipes 93. Through the design of the insertion tube 91 and the connecting pipe 92, the first airbag strips 6 on the second sliding door 4 can be inflated, which enhances the overall sealing performance of the partition device and prevents temperature leakage and cross-influence.
[0038] The operation steps of the above embodiment are as follows:
[0039] During the high and low temperature test, the motor 51 is started by the control device, which drives the gear 52 to rotate. The gear 52 meshes with the rack 53 on the first sliding door 3 and the second sliding door 4, driving the sliding door to slide along the mounting base 2. The fixed pulley 54 plays a guiding and supporting role, ensuring that the sliding door slides smoothly and the sliding door opens.
[0040] The vehicles to be tested are placed inside the first compartment 11 and the second compartment 12 respectively, and their sliding doors are closed by controlling the device.
[0041] After the first sliding door 3 and the second sliding door 4 are completely closed, the air pump 7 in the underground space 13 is activated;
[0042] The air pump 7 starts working and inflates the first airbag strip 6 on the first sliding door 3 and the second sliding door 4 through the air supply pipe 701 and the connector 9. At the same time, since the first sliding door 3 is provided with a second airbag strip 8 near the second sliding door 4, the first airbag strip 6 inflates the second airbag strip 8 through the connecting pipe 93.
[0043] As the airbag strips inflate, they fit tightly into the gaps between the mounting groove, the ground groove 101, the partition wall 15, and the sliding door, forming an effective sealing barrier to prevent temperature leakage and cross-influence between the compartments.
[0044] According to the testing requirements, the target temperatures of the first chamber 11 and the second chamber 12 are set through the control panel or remote control system;
[0045] Once the temperature inside the chamber has stabilized, the testing will begin.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
