Description

Technical Field

[0001] The invention relates to the technical field of military tent production, in particular to a waterproof detection device for military tents. 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 in severe weather conditions such as heavy rain and blizzards, providing 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 the waterproof testing of military tents: 1. When testing the waterproofness of military tents, the tent must first be installed under the corresponding nozzle, 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 there is water seepage 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, making the test results incomplete and unable to fully reflect the waterproof performance of the military tent. In addition, the method of observing whether there is water seepage inside the tent by naked eye 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. As a result, 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.

The upper end surface of the sliding seat 412 is threadedly connected to the front-back symmetrical bolts 413 through a screw hole opened through it.

[0038] See also Figure 1 、 Figure 2 and Figure 3 The fixing part 42 includes a fixing cylinder 421, a first screw 422, a pressure plate 423 and a rubber plate 424. The upper end surface of the sliding seat 412 is fixedly installed with a fixing cylinder 421 located between the corresponding front and rear symmetrical bolts 413. A sliding groove is provided on the outer ring wall of the fixing cylinder 421. The first screw 422 is installed through the bearing in the fixing cylinder 421. A pressure plate 423 threadedly connected to the first screw 422 is slidably installed in the sliding groove. The upper end surface of the sliding seat 412 is fixedly installed with a rubber plate 424 located below the corresponding pressure plate 423.

[0039] See also Figure 1 、 Figure 4 、 Figure 5 and Figure 6The lifting part 51 includes a second screw 511, a support slider 512, a support shaft 513 and a rotating seat 514. The water absorbing part includes a semi-arc frame 515, an electric slider 516, a squeezing roller 517 and a collecting trough 518. The second screw 511 that passes through the lower end surface of the support slide rail 3 is installed in the support slide rail 3 through a bearing. The support slide rail 3 is slidably installed with a support slider 512 that is threadedly connected to the corresponding second screw 511. The front and rear symmetrical support sliders 512 are both installed with a support shaft 513 on the side close to each other through a bearing. The end of the support shaft 513 close to each other is fixedly installed with a rotating seat. 514, a semi-arc frame 515 is magnetically adsorbed between the front and rear symmetrical rotating seats 514, and a sponge block (not shown in the figure) is fixedly installed on the outer ring wall of the semi-arc frame 515 through an opened placement groove, and a left-right symmetrical electric slider 516 is slidably installed on the semi-arc frame 515, and a squeezing roller 517 for squeezing the sponge block is fixedly installed between the left-right symmetrical electric sliders 516. A collecting groove 518 is fixedly installed at the lower end of the semi-arc frame 515, and the front and rear ends of the placement groove are penetrated by evenly distributed through holes connected to the collecting groove 518, and an eight-shaped guide plate is installed at the upper end of the collecting groove 518.

[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. Then, the sliding seat 412 on the corresponding drainage groove 411 can be slid and moved to the edge of the tent. At this time, the worker holds the electric rotary 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 with the electric rotary 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] The worker then placed the semi-arc frame 515 inside the tent. The rotating bases 514 on either side magnetically secured the frame 515 in place, ensuring that the sponge on the frame adhered snugly to the area of the tent being sprayed. To change the test location, the semi-arc frame 515 was removed from the rotating bases 514 and then reinstalled after the adjustment.

[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 does 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. The lower end of the second screw 511 is fixedly sleeved with a pulley 521, and the pulleys 521 are connected by a belt 522. The lower end of one of the supporting slide rails 3 is fixedly installed with a first motor 523 with an output end fixedly connected to the corresponding second screw 511.

[0044] See also Figure 1 and Figure 5 The rotating part 53 includes a second motor 531 and a first gear 532, wherein a first transmission gear is fixedly sleeved on one of the support shafts 513, and a second motor 531 is fixedly mounted on the side support slider 512, and an output end of the second motor 531 is fixedly sleeved with a first gear 532 meshing with the first transmission gear.

[0045] See also Figure 1 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 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 and rear symmetrical rotating seat 514. A mounting groove 542 is opened in the semicircular bracket 541. 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 slide is opened 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 to it, 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 rotates synchronously, so that the supporting sliders 512 on both sides rise synchronously, thereby raising the testing mechanism 6 through the semicircular bracket 541 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 spraying 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 with the rotating seat 514 as the center, thereby changing the spraying angle of the test mechanism 6.

[0048] See also Figure 1 、 Figure 7 、 Figure 9 and Figure 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 and 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 between the left and 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 、 Figure 9 and Figure 10 The limiting part 62 includes a connecting shaft 621 and a roller 622. The connecting shaft 621 is symmetrical in front and back about the matching shaft 613 and is installed between the left and 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 that 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 testing 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 and rear symmetrical connecting shafts 621 will slide in the limiting slide groove 543, providing stable support for the executive part 63, so that the executive part 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 、 Figure 9 and Figure 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 installed 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 so that the actuator 63 is in a fixed state. Then, the connecting pipe of the external water pump fixedly mounted on the base 1 is connected to the water inlet pipes 631 on both sides, thereby supplying 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 detection of the outer layer of the tent is completed, the spraying position can be adjusted again by the rotating mechanism 5 and the testing mechanism 6 to perform static waterproof tests on different surfaces of the tent.

[0053] When conducting 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 into a moving state, so as to continuously adjust the spraying angle of the nozzle 632 and the water pressure at the same time, simulating the multi-directional, multi-angle and multi-intensity rain impact 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 seeps into the interior, the seeped water will be absorbed by the sponge block. Therefore, after each test, the electric slider 516 is activated to drive the squeezing roller 517 to squeeze the sponge block to ensure that the sponge block can be reused. 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 intuitively judged by observing the water level in the collection tank 518. If there is no water in the collection tank 518, the tent is rated as having good waterproof performance. Conversely, if the water level in the collection tank 518 exceeds the set value, the tent is rated as having poor waterproof performance. In order to intuitively 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 first, and quickly find the location of the water seepage based on the distribution of water stains on the sponge block, and then record the water seepage points of the tent so that you can make corresponding improvements later.

[0056] Working principle: When a military tent needs to be tested for waterproofing, the worker first places the military tent to be tested on the test carrier 2 and completes the assembly. Then, the worker can slide the sliding seat 412 on the corresponding drainage groove 411 and move it to the edge of the tent. At this time, the worker holds an electric rotary tool to limit and fix the tent through the fixing mechanism 4. Then, the worker 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 so that the actuator 63 is in a fixed state, and then the external water pump is started to provide 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 test at this position of the outer layer of the tent is completed, the spray position can be adjusted again by the rotating mechanism 5 and the testing mechanism 6 to perform static waterproof tests on different surfaces of the tent.

[0058] When conducting 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 into a moving state, so as to continuously adjust the spraying angle of the nozzle 632 and the water pressure at the same time, simulating the multi-directional, multi-angle and multi-intensity rain impact 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 collection tank 518 through the through hole. The waterproof performance is intuitively judged by observing the amount of water 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 amount in the collection tank 518 exceeds the set value, the tent is evaluated as having poor waterproof performance.

[0060] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
