Description

Technical Field

[0001] The invention relates to the technical field of military tent production, in particular to a military tent waterproof detection device. Background Art

[0002] Military tents are usually used in field combat, field life and temporary camping. It is necessary to ensure that soldiers and equipment are effectively protected in various harsh environments. Therefore, the waterproof performance of military tents is particularly important. After the production of military tents, their waterproof performance needs to be tested to ensure that the tents can effectively block moisture penetration under severe weather conditions such as heavy rain and blizzards, and provide comprehensive protection for soldiers and equipment, thereby ensuring that military tents can meet the actual needs of military operations.

[0003] At present, there are the following shortcomings in waterproof testing of military tents: 1. When testing the waterproofness of military tents, the tent must be installed under the corresponding nozzle first, and then the nozzle is used to spray the tent in a single direction. Then, the waterproofness of the military tent is determined by observing whether water seepage occurs inside the tent. The single-direction spraying cannot simulate the multi-directional and multi-angle rain impact that the tent may encounter in actual use, so that the test results are not comprehensive enough, and thus cannot fully reflect the waterproof performance of the military tent. Moreover, the method of observing whether water seepage occurs inside the tent by naked eyes is inefficient and prone to omissions. At the same time, it is difficult to accurately determine the specific location of the leakage and the amount of leakage, and thus it is impossible to accurately assess the waterproof performance of the tent based on the test results; 2. In the process of waterproof testing of military tents, only a single water pressure is used to spray the tent, and the waterproof performance of the tent under different water pressures cannot be detected, so it is impossible to simulate the actual waterproof performance of the tent when encountering rainfall of different intensities.

[0040] During the specific work, when it is necessary to conduct a waterproof test on the military tent, the worker first places the military tent to be tested on the test carrier 2 and assembles it, and then slides the sliding seat 412 on the corresponding drainage groove 411 and moves it to the edge of the tent. At this time, the worker holds the electric rotating tool to rotate the bolt 413, so that the front and rear symmetrical bolts 413 first fix the sliding seat 412 on the test carrier 2, and then rotates the first screw 422 again through the electric rotating tool to make the pressing plate 423 descend, so that the pressing plate 423 clamps the edge of the tent on the rubber plate 424, and then uses the same method to limit and fix other positions of the tent, thereby ensuring that the tent maintains the same state and position during the test.

[0041] Then the worker places the semi-arc frame 515 in the fixed tent, and the rotating seats 514 on both sides fix the semi-arc frame 515 in the tent through magnetic adsorption, and the sponge block on the semi-arc frame 515 can be closely attached to the part of the tent that is sprayed. When the test position needs to be changed, the semi-arc frame 515 is first removed from the rotating seats 514, and when the position is adjusted, the semi-arc frame 515 is put back.

[0042] It should be noted that during the test, the electric slider 516 drives the squeezing roller 517 to be located at the end of the semi-arc frame 515, which will not squeeze the sponge block, so that the sponge block can fit the inner wall of the tent.

[0043] See also Figure 1 and Figure 4The driving part 52 includes a pulley 521, a belt 522 and a first motor 523.

[0045] See also Figure 1 , Figure 5 , Figure 7 , Figure 8 and Fig.10 The main body 54 includes a semicircular bracket 541, a mounting groove 542 and a limiting slide groove 543. The semicircular bracket 541 is fixedly installed on the front-back symmetrical rotating seat 514. The semicircular bracket 541 is provided with a mounting groove 542. The upper ring wall inside the mounting groove 542 is provided with teeth evenly distributed along its circumference. The semicircular bracket 541 is fixedly installed with a left-right symmetrical limiting slide groove 543. An arc slideway is provided through the semicircular bracket 541 and the left-right symmetrical limiting slide groove 543.

[0046] During specific operation, after the fixing mechanism 4 completes the limiting fixation of the military tent, the tent can be sprayed through the testing mechanism 6. When the static spraying height of the testing mechanism 6 needs to be adjusted, the first motor 523 is started to rotate with the second screw 511 fixed thereto, and with the cooperation of the pulley 521 and the belt 522, the second screw 511 in the supporting slide rails 3 on both sides rotate synchronously, so that the supporting sliders 512 on both sides rise synchronously, thereby raising the testing mechanism 6 through the semicircular bracket 541, so as to adjust the spraying height of the testing mechanism 6. During this process, the second motor 531 is in an unstarted state, so that the semicircular bracket 541 will not deviate to the left or right, so that the spraying height of the testing mechanism 6 can be smoothly adjusted.

[0047] When the static spray angle of the test mechanism 6 needs to be adjusted, the second motor 531 is started to rotate it with the first gear 532, and with the cooperation of the first gear 532 and the first transmission gear, the support shaft 513 rotates with the rotating seat 514, so that the semicircular bracket 541 rotates with the test mechanism 6 around the rotating seat 514, thereby changing the spray angle of the test mechanism 6.

[0048] See also Figure 1 , Figure 7 , Fig. 9 and Fig.10 The walking part 61 includes a trapezoidal plate 611, a connecting plate 612, a matching shaft 613, a third motor 614 and a second gear 615. The trapezoidal plate 611 is slidably installed on the limiting slide groove 543. The lower ends of the left-right symmetrical trapezoidal plates 611 are fixedly installed with a connecting plate 612 located on the inner side of the semicircular bracket 541. The matching shaft 613 is installed through the bearings set between the left-right symmetrical trapezoidal plates 611. The matching shaft 613 is fixedly sleeved with a second gear 615 located in the installation groove 542 and meshing with the teeth. A third motor 614 with an output end fixedly connected to the matching shaft 613 is fixedly installed on one of the trapezoidal plates 611.

[0049] See also Figure 1 , Figure 7 , Fig. 9 and Fig.10 The limiting part 62 includes a connecting shaft 621 and a roller 622. The connecting shaft 621 which is symmetrical in front and back about the matching shaft 613 is installed between the left-right symmetrical trapezoidal plates 611 through a bearing. The connecting shaft 621 is slidably connected to the arc slide. The connecting shaft 621 is fixedly sleeved with a roller 622 which is symmetrical in front and back and slidably connected to the corresponding limiting slide groove 543.

[0050] During specific operation, when the rotating mechanism 5 adjusts the spraying angle of the test mechanism 6, the third motor 614 can be started at the same time to rotate the matching shaft 613, and through the cooperation of the second gear 615 and the teeth, the trapezoidal plates 611 and the connecting plates 612 on both sides can slide along the inner side of the semicircular bracket 541. During the movement, the corresponding rollers 622 on the front-to-back symmetrical connecting shaft 621 will slide in the limiting slide groove 543, providing stable support for the actuator 63, so that the actuator 63 can change the spraying direction laterally. Through the adjustable spraying direction, the change in rain spraying direction caused by wind direction change can be more realistically simulated.

[0051] See also Figure 1 , Fig. 9 and Fig.10 The execution part 63 includes a water inlet pipe 631 and a nozzle 632 . A plurality of nozzles 632 are evenly distributed in an array on the lower end surface of the connecting plate 612 . A water inlet pipe 631 connected to the plurality of nozzles 632 is fixedly mounted on the connecting plate 612 .

[0052] During specific operation, when a static water pressure test is required, the third motor 614 and the second motor 531 are stopped to make the actuator 63 in a fixed state, and then the connecting pipe of the external water pump fixedly installed on the base 1 is connected to the water inlet pipes 631 on both sides, so as to supply water to the multiple nozzles 632 on the connecting plates 612 on both sides, and the waterproof performance of the outer layer of the tent is tested at different water pressures at the same position by gradually increasing the water pressure. After the outer layer of the tent is tested at this position, the spraying position can be adjusted again by the rotating mechanism 5 and the testing mechanism 6, so as to perform static waterproof tests on different surfaces of the tent.

[0053] When performing a dynamic flushing test, the third motor 614 and the second motor 531 are operated to cooperate with the rotating mechanism 5 and the testing mechanism 6 to put the actuator 63 in a moving state, so as to continuously adjust the spray angle of the nozzle 632 and the water pressure at the same time, simulating the multi-directional, multi-angle and multi-intensity rain impact state encountered by the tent in actual use, so as to evaluate the waterproof performance of the tent under different weather conditions.

[0054] During the waterproof test, after the nozzle 632 sprays for a certain period of time, if the tent is damaged and water penetrates into the interior, the penetrated water will be absorbed by the sponge block. Therefore, after each test, the electric slider 516 is started to drive the squeezing roller 517 to squeeze the sponge block to ensure that the sponge block can be reused, and the squeezed water falls into the collection tank 518 through the through hole. The eight-shaped guide plate prevents the squeezed water from splashing outside. The waterproof performance can be visually judged by observing the water volume in the collection tank 518. If there is no water in the collection tank 518, the tent is evaluated as having good waterproof performance. On the contrary, when the water volume in the collection tank 518 exceeds the set value, the tent is evaluated as having poor waterproof performance. In order to visually judge the amount of water in the collection tank 518, a scale line can be set on the inner wall of the collection tank 518.

[0055] After each test, you can observe the sponge block with your naked eyes instead of squeezing it, and quickly find the water seepage location based on the distribution of water stains on the sponge block, and then record the water seepage points of the tent to facilitate subsequent corresponding improvements.

[0056] Working principle: When it is necessary to conduct a waterproof test on a military tent, the worker first places the military tent to be tested on the test carrier 2 and assembles it, and then slides the sliding seat 412 on the corresponding drainage groove 411 and moves it to the edge of the tent. At this time, the worker holds an electric rotating tool to limit and fix the tent through the fixing mechanism 4, and then places the semi-arc frame 515 in the fixed tent, so that the sponge block on the semi-arc frame 515 can fit tightly against the part of the tent that is sprayed.

[0057] When a static water pressure test is required, the third motor 614 and the second motor 531 are stopped to keep the actuator 63 in a fixed state, and then the external water pump is started to provide water to the nozzles 632 on the connecting plates 612 on both sides, and the waterproof performance of the outer layer of the tent is tested at different water pressures at the same position by gradually increasing the water pressure. After the test of the outer layer of the tent at this position is completed, the spray position can be adjusted again by the rotating mechanism 5 and the testing mechanism 6, so as to perform a static waterproof test on different surfaces of the tent.

[0058] When performing a dynamic flushing test, the third motor 614 and the second motor 531 are operated to cooperate with the rotating mechanism 5 and the testing mechanism 6 to put the actuator 63 in a moving state, so as to continuously adjust the spray angle of the nozzle 632 and the water pressure at the same time, simulating the multi-directional, multi-angle and multi-intensity rain impact state encountered by the tent in actual use, so as to evaluate the waterproof performance of the tent under different weather conditions.

[0059] During the above-mentioned waterproof test, after the nozzle 632 sprays for a certain period of time, the electric slider 516 is started to squeeze the sponge, and the squeezed water falls into the collecting groove 518 through the through hole. The waterproof performance is intuitively judged by observing the water amount in the collecting groove 518. If there is no water in the collecting groove 518, the tent is evaluated as having good waterproof performance. On the contrary, when the water amount in the collecting groove 518 exceeds the set value, the tent is evaluated as having poor waterproof performance.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
