Description

Technical Field

[0001] This invention relates to the field of fabric testing technology, specifically to a real-time tension testing device and method for tent fabric. Background Technology

[0002] With the widespread application of flexible composite materials in tents, tents can better adapt to special environments such as extreme cold, storms, or rain. When flexible composite materials are subjected to random loads such as snow accumulation and precipitation, the surface tension distribution of the material will fluctuate drastically. Without high-precision real-time interfacial tension monitoring methods, the material is very susceptible to macroscopic tearing or fatigue failure due to local stress concentration.

[0003] Existing conventional tension detection solutions, such as those in application number CN201621203847.0, rely primarily on the mechanical tension detection of external tension components. When the external load increases, the tension component is stretched, and the tension detection device monitors the tension change in the component in real time. When the detected value exceeds a safety threshold, the detection device will sound an alarm, prompting personnel to evacuate in time to avoid injury. However, this type of solution has the following limitations in practical applications: Existing technologies often focus on measuring the tensile force of external traction components. For tents that are integrally molded or lack external fasteners, this method cannot be used for detection. Furthermore, this solution requires the tension sensor to be placed on the outside for tension detection, making the detection device susceptible to external factors. Summary of the Invention

[0004] The purpose of this invention is to provide a real-time tension detection device and method for tent fabric, so as to solve the problem that force sensors cannot be directly installed in tents with an integrated roof and sidewalls.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A real-time tension detection device for tent fabric includes a frame on which fabric is disposed. The fabric includes a roof and sidewalls, with the sidewalls supported by the frame. Four detection brackets are fixedly connected to the frame, supporting the roof. Pressure detection plates are slidably connected to the detection brackets, with a spring between the pressure detection plates and the detection brackets. The pressure detection plates contact the junction of the roof and sidewalls. A detection component is disposed on the frame, with the pressure detection plates on the four detection brackets all in contact with the detection component. When the roof is subjected to pressure, the fabric squeezes the pressure detection plates, causing the pressure detection plates to shift and squeeze the detection component.

[0006] This design incorporates a pressure detection plate at the junction of the fabric roof and sidewalls. When external loads such as snow act on the roof, it deforms downwards, compressing the pressure detection plate. Under the pressure of the fabric, the plate slides along a detection bracket, simultaneously compressing a spring. This converts the pressure from the fabric's tension changes into displacement of the pressure detection plate. This displacement is transmitted through contact with the detection components, allowing the components to sense and record changes in the roof's tension in real time. When the tension becomes excessive, it promptly alerts personnel inside the tent, prompting them to take appropriate measures, such as clearing snow or evacuating the tent. This design improves safety when personnel are asleep or unaware of external dangers. The four detection brackets, each corresponding to a different position on the tent roof, allow for multi-angle monitoring of the roof's tension, preventing omissions due to single-point detection and ensuring a comprehensive understanding of the fabric's overall tension. The detection components are mounted on the frame and encased in the fabric, making them less susceptible to external influences. This design also allows personnel inside the tent to easily observe the data. Furthermore, the elastic movement of the pressure detection plate cushions the fabric when subjected to significant pressure, preventing damage from sudden impacts and enhancing the fabric's impact resistance.

[0007] Preferably, the detection assembly includes a tension detection rope, which is wound in a shape consistent with the ceiling. Two connecting rods are fixedly connected to one end of the pressure detection plate, and a push block is fixedly connected to one end of each connecting rod. All four push blocks on the pressure detection plate are in contact with the tension detection rope. A force sensor and an alarm device are provided on the tension detection rope.

[0008] Because the four pressure testing plates are dispersed, multiple testing components are needed to test all of them, which increases cost and complicates the structure. Therefore, this design uses a tension testing rope. A single tension testing rope can test all four pressure testing plates on the testing supports, effectively simplifying the device structure and reducing cost. The tension testing rope is wound in a shape consistent with the ceiling, ensuring all four pressure testing plates are in contact with it. When any pressure testing plate shifts due to ceiling deformation, the connecting rod connected to that plate moves a pusher block synchronously. The pusher block then applies a thrust to the tension testing rope. Because the pressure testing plates on the four pressure testing plates... All push blocks are in contact with the same tension detection rope. Regardless of the direction or position of the tent's tension, any change in the tension will be transmitted to the tension detection rope through the push blocks, causing a change in the rope's tension. The force sensor on the tension detection rope will then detect the tension change in real time. When the tension value detected by the force sensor exceeds a preset safety threshold, an alarm device will be triggered. The alarm device can send an alert to the personnel inside the tent via sound, light, or wireless signals, thereby achieving real-time monitoring and hazard warning of the fabric tension. Therefore, this design not only reduces the complexity and cost of the device but also ensures sensitive capture of tension changes in different positions of the fabric, achieving a unified approach to overall monitoring and precise early warning.

[0009] Preferably, the tension detection rope is slidably connected with four connecting rings, the frame has four mounting holes, and a mounting block is provided on one side of each connecting ring. All mounting blocks can be detachably installed in the mounting holes.

[0010] Because tents require frequent disassembly and assembly, the tension testing rope also needs to be removed during tent disassembly and reinstalled during tent assembly. This not only increases the time cost of tent setup and storage but may also cause the tension testing rope to shift position due to improper installation, affecting the testing accuracy. This design addresses this by sliding four connecting rings onto the tension testing rope and creating corresponding mounting holes on the frame. Mounting blocks on one side of the connecting rings can be detachably installed into the mounting holes. During tent setup, simply inserting the mounting blocks from the connecting rings into the mounting holes in the frame quickly secures the tension testing rope. The four mounting holes are fixed in position, ensuring that the tension detection rope can be accurately wound into a shape consistent with the tent roof during each installation and make tight contact with the push blocks on the four pressure detection plates. When the tent needs to be disassembled, the mounting blocks can be pulled out of the mounting holes to separate the tension detection rope from the frame. The operation is convenient and efficient, greatly simplifying the tent assembly and disassembly process. In addition, the sliding fit between the connecting ring and the tension detection rope can adapt to the slight deformation of the fabric under different tension states, avoiding the impact of the displacement transmission of the pressure detection plates due to the tension detection rope being too fixed, thus ensuring the stability and reliability of the detection device under various working conditions.

[0011] Preferably, the connecting rod has a first inclined surface on its upper and lower sides, a slider on its upper and lower sides, a second spring between the slider and the inner wall of the detection bracket, a second inclined surface on the slider, the first inclined surface contacting the second inclined surface, and the second inclined surface facing the inside of the fabric.

[0012] Because the tent roof is exposed to outdoor conditions, in addition to snow accumulation, it is also affected by wind and rain. The pressure exerted by the wind on the roof is intermittent, causing the pressure detection plate to be frequently squeezed and reset. This not only accelerates mechanical wear, but also generates additional noise, affecting the people inside the tent. Therefore, this design incorporates inclined planes on both sides of the connecting rod, and also includes sliders on both sides of the connecting rod. When external loads such as snow act on the roof, the roof compresses the pressure detection plate. Under the pressure of the fabric, the pressure detection plate drives the connecting rod and push block to slide along the detection bracket, compressing the tension detection rope to complete the detection. During this process, the slider remains in contact with the connecting rod. However, since the second inclined plane faces the inside of the fabric, it does not affect the movement of the connecting rod. When the pressure on the roof decreases or disappears, the pressure detection plate is reset by the action of the first spring. At this time, since the connecting rod moves in the opposite direction of the second inclined plane, it will press against the sliders on both sides, thus slowing down the reset speed of the pressure detection plate. Therefore, this design avoids the pressure detection plate from rebounding quickly due to the elasticity of the first spring, thereby reducing the collision and friction between mechanical parts, effectively reducing wear and noise, extending the service life of the device, and providing a quieter resting environment for people inside the tent.

[0013] Preferably, a locking hole is provided on one side of the connecting rod, the locking hole cooperates with a slider on one side, an unlocking hole is provided on the slider, an unlocking block is elastically slidably connected to the detection bracket, and an inclined surface three is provided at one end of the unlocking block near the unlocking hole, the inclined surface three contacting the edge of the unlocking hole.

[0014] This design incorporates a locking hole on one side of the connecting rod. When the tent is disassembled and stored, the pressure detection plate can be manually pushed into the detection bracket. The connecting rod moves synchronously with the pressure detection plate. When the locking hole reaches the slider position, the slider engages under elastic pressure, securing the pressure detection plate to the detection bracket. To re-erect the tent and activate the detection function, simply press the unlocking block from the outside of the detection bracket. The inclined surface on the unlocking block pushes against the edge of the unlocking hole on the slider, causing it to move out of the locking hole. The pressure detection plate then returns to its initial working position under the action of spring one, re-engaging with the fabric at the junction of the tent roof and side walls, ensuring the detection device can respond correctly to external loads. Therefore, this design not only reduces the overall size of the detection bracket when stored, but also... This design also prevents the pressure detection plate from sliding on the detection bracket during transport, thus preventing damage from collisions between the pressure detection plate and the inner wall of the bracket. Furthermore, when the tent is erected in good weather, locking the pressure detection plate reduces noise and wear, improving the device's practicality and lifespan. Additionally, when the wind force on the roof is excessive and remains constant, if the frequency of the wind speed pulse coincides with the reciprocating frequency of the spring, resonance will occur, causing the tent to sway more and more, accelerating wear on the overall structure. This design locks the tent after the wind force reaches the alarm threshold, allowing personnel inside to evacuate promptly. The tent remains locked in a fixed position, reducing wear and extending the overall lifespan of the structure.

[0015] Preferably, the push block has an arc groove, and the inner wall of the arc groove has rounded chamfers on both sides, and the tension detection rope is in contact with the inner wall of the arc groove.

[0016] The contact stability between the push block and the tension detection rope directly affects the accuracy of tension transmission. If the contact area is too small or the edges are sharp, the tension detection rope may shift or even wear under force. This design increases the contact area between the push block and the tension detection rope by creating an arc groove on the push block, allowing the tension detection rope to be embedded in the groove. This effectively prevents the tension detection rope from slipping off the push block during force application, ensuring that the displacement of the pressure detection plate can be stably transmitted to the tension detection rope. At the same time, the rounded chamfers on both sides of the inner wall of the arc groove avoid the cutting and friction of the tension detection rope by traditional right-angled edges, significantly reducing the risk of wear and breakage of the tension detection rope due to long-term use and extending its service life. In addition, the arc-shaped contact method makes the force distribution of the push block on the tension detection rope more uniform, reducing local stress concentration and further ensuring the accuracy and reliability of the force sensor detection data, providing structural protection for the accurate monitoring of fabric tension.

[0017] Preferably, the testing bracket is provided with a protective sleeve, which encloses the pressure testing plate.

[0018] This design, by installing a protective sleeve on the testing bracket to enclose the pressure testing plate, effectively prevents external dust, rainwater, snow particles, and other impurities from entering the testing bracket. This avoids impurities adhering to the sliding parts of the pressure testing plate or the spring, preventing the pressure testing plate from becoming stuck or the spring from losing its elasticity due to impurity accumulation. This ensures that the pressure testing plate can flexibly respond to changes in fabric tension, guaranteeing the sensitivity and stability of the testing device. Simultaneously, it prevents the fabric from being trapped between the pressure testing plate and the testing bracket, and the sleeve also prevents the fabric from being scratched by the edges of the pressure testing plate during sliding, extending the fabric's lifespan. Furthermore, the sleeve can be made of a flexible material, further isolating the noise generated by the sliding between the pressure testing plate and the testing bracket without affecting the normal displacement of the pressure testing plate, thus improving the quietness inside the tent.

[0019] A method for detecting the tension of a tent fabric in real time, comprising the following steps: S1. The device is in standby mode. The pressure detection plate is in contact with the junction of the roof and the push block lightly touches the tension detection rope. The force sensor records the initial reference tension of the tension detection rope. S2. The snow accumulation on the roof causes deformation. The deformation force pushes the pressure detection plate to slide inward along the detection bracket, compressing the spring. The pressure detection plate drives the push block to move through the connecting rod. The push block squeezes the tension detection rope, increasing its tension. S3. The force sensor monitors the tension of the tension detection rope in real time. When the tension value exceeds the preset safety threshold, the alarm device is immediately triggered to issue a danger warning to the people inside the tent through sound. S4. When encountering intermittent loads such as wind, inclined plane one and inclined plane two disengage, and the slider does not generate resistance, ensuring detection sensitivity. During reset, inclined plane one presses inclined plane two, forcing the slider to slide to both sides of the compressed spring two, slowing down the reset speed and avoiding mechanical impact and false alarms.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses a pressure detection plate installed at the junction of the fabric tent roof and side wall. When external loads such as snow are applied to the tent roof, the pressure detection plate slides along the detection bracket, converting the pressure of the fabric tension change into displacement. By detecting the tent roof tension with the detection component, if the tension is too high, it will promptly remind the personnel inside the tent to clear the snow or evacuate, thus improving personnel safety. The four detection brackets correspond to different positions on the tent roof, monitoring the tent roof tension from multiple angles to ensure a comprehensive understanding of the overall tension status of the fabric. The detection component is set on the frame and wrapped in the fabric, making it less susceptible to external factors and also facilitating the observation of the detection data by the personnel inside the tent.

[0021] 2. This invention features a tension detection rope that is wound in a shape consistent with the ceiling. When any pressure detection plate shifts due to ceiling deformation, pushers apply a pushing force to the tension detection rope. Since all four pushers are in contact with the same tension detection rope, any tension change in the direction or position of the ceiling will be transmitted to the tension detection rope, causing a change in its tension. The force sensor on the tension detection rope detects the tension change in real time. When the tension value exceeds a preset safety threshold, an alarm is issued, realizing real-time monitoring and danger warning of the fabric tension. This design achieves comprehensive detection with a single sensor, reducing the complexity and cost of the device.

[0022] 3. This invention uses four connecting rings that slide on the tension testing rope and corresponding mounting holes in the frame. The mounting block on one side of the connecting ring can be detachably installed with the mounting hole. When setting up the tent, the tension testing rope can be quickly fixed. The four mounting holes are fixed in position to ensure that the tension testing rope can be accurately wound into a shape consistent with the tent roof and in close contact with the pressure testing plate push block. When disassembling the tent, the mounting block can be pulled out to separate the tension testing rope from the frame. The operation is convenient and efficient, and the disassembly and assembly process is simplified. Attached Figure Description

[0025] This invention provides a device and method for real-time tension detection of tent fabric, the technical solution of which is as follows: Please see Figures 1 to 8 A real-time tension detection device for tent fabric includes a frame 1, on which a fabric 2 is mounted. The fabric 2 includes a canopy roof 3 and side walls 4, which are supported by the frame 1. Four detection brackets 5 are fixedly connected to the frame 1, supporting the canopy roof 3. Pressure detection plates 6 are slidably connected to the detection brackets 5, and springs 7 are provided between the pressure detection plates 6 and the detection brackets 5. The pressure detection plates 6 contact the junction of the canopy roof 3 and the side walls 4. A detection component is mounted on the frame 1, and the pressure detection plates 6 on the four detection brackets 5 are all in contact with the detection component. When the canopy roof 3 is subjected to pressure, the fabric 2 squeezes the pressure detection plates 6, causing the pressure detection plates 6 to shift and squeeze the detection component.

[0026] Please see Figures 1 to 8 The detection assembly includes a tension detection rope 8, which is wound in a shape consistent with the canopy 3. Two connecting rods 9 are fixedly connected to one end of a pressure detection plate 6, and a push block 10 is fixedly connected to one end of each connecting rod 9. The push blocks 10 on the four pressure detection plates 6 are all in contact with the tension detection rope 8. A force sensor 11 and an alarm device 12 are provided on the tension detection rope 8. The force sensor 11 is a pressure sensor in the prior art, and the alarm device 12 is a buzzer alarm in the prior art. Four connecting rings 13 are slidably connected to the tension detection rope 8. The frame 1 has four mounting holes 14. A mounting block 15 is provided on one side of the connecting ring 13. The mounting blocks 15 can be detachably installed in the mounting holes 14. An inclined surface 16 is provided on the upper and lower sides of the connecting rod 9. A slider 17 is provided on the upper and lower sides of the connecting rod 9. A spring 18 is provided between the slider 17 and the inner wall of the detection bracket 5. An inclined surface 19 is provided on the slider 17. The inclined surface 16 is in contact with the inclined surface 19, and the inclined surface 19 faces the inner side of the fabric 2.

[0027] Please see Figures 1 to 8 A locking hole 23 is provided on one side of the connecting rod 9. The locking hole 23 cooperates with the slider 17 on one side. An unlocking hole 22 is provided on the slider 17. An unlocking block 20 is elastically slidably connected to the detection bracket 5. An inclined surface 21 is provided at one end of the unlocking block 20 near the unlocking hole 22. The inclined surface 21 contacts the edge of the unlocking hole 22. An arc groove 24 is provided on the push block 10. An arc chamfer is provided on both sides of the inner wall of the arc groove 24. The tension detection rope 8 contacts the inner wall of the arc groove 24. A protective sleeve 25 is provided on the detection bracket 5. The protective sleeve 25 wraps the pressure detection plate 6 inside.

[0028] Please see Figures 1 to 8 The detection method of the real-time tension detection device for tent fabric is as follows: 1. External load application stage As snowflakes begin to accumulate on the tent roof 3, the weight of the snow acts as an external load on the fabric 2 of the roof 3. Under this gravity, the roof 3 deforms downwards. Since the pressure detection plate 6 is already in contact with the junction of the roof 3 and the side wall 4, the downward deformation of the roof 3 compresses this contact point, thus applying a thrust towards the inside of the tent to the pressure detection plate 6. Under this thrust, the pressure detection plate 6 overcomes the elasticity of the spring 7 and slides inwards along the detection bracket 5. At this time, the spring 7 is further compressed, converting the tension of the fabric 2 into the displacement of the pressure detection plate 6. The sliding of plate 6 causes the connecting rod 9, which is fixedly connected to it, to move synchronously. The push block 10 at the end of the connecting rod 9 also moves towards the tension detection rope 8. The arc groove 24 on the push block 10 squeezes the tension detection rope 8. Since all the push blocks 10 are in contact with the same tension detection rope 8, the pushing force of the push block 10 will directly cause the tension of the tension detection rope 8 to increase. The force sensor 11 set on the tension detection rope 8 senses the change in tension in real time. When the tension value exceeds the preset safety threshold, the alarm device 12 is triggered. The alarm device 12 issues a danger warning to the people in the tent through sound, reminding them to clear the snow or evacuate immediately.

[0029] 2. Interference Suppression and Buffering Phase When the roof 3 is subjected to intermittent and irregular pressure such as wind, the pressure detection plate 6 will produce frequent small-amplitude displacements.

[0030] When under pressure: The pressure detection plate 6 drives the connecting rod 9 to move inward. Since the inclined surface 16 on the connecting rod 9 is in contact with the inclined surface 19 on the slider 17, and the inclined surface 19 is facing inward towards the fabric 2, the inclined surface 16 is "leaving" relative to the inclined surface 19. The slider 17 will not generate resistance to the movement of the connecting rod 9, thus ensuring the sensitive response of the pressure detection plate 6 to the snow pressure.

[0031] During reset movement: When the external pressure disappears, the pressure detection plate 6 is subjected to the reset force of spring 7 and attempts to quickly rebound outward. At this time, the inclined surface 16 on the connecting rod 9 will press the inclined surface 19 of the slider 17 in the opposite direction. Due to the orientation of the inclined surface 19, the movement of the connecting rod 9 will force the sliders 17 on both sides to overcome the elastic force of spring 18 and slide to both sides, thereby consuming the reset kinetic energy and slowing down the reset speed of the pressure detection plate 6. This design avoids the pressure detection plate 6 from rapidly impacting the detection bracket 5 due to the elastic force of spring 7, effectively reducing mechanical wear and noise, and avoiding frequent false alarms caused by wind pressure fluctuations.

[0032] 3. Storage When the tent needs to be disassembled for storage, personnel can manually push the pressure detection plate 6 to slide it into the detection bracket 5 against the elastic force of the spring 7. At this time, the connecting rod 9 fixed on the pressure detection plate 6 moves forward. When the locking hole 23 moves to the position of the slider 17, the slider 17 automatically engages in the locking hole 23 under its own elasticity, locking the pressure detection plate 6 in the retracted state. At the same time, the mounting block 15 on one side of the connecting ring 13 is pulled out from the mounting hole 14 of the frame 1, so that the entire tension detection rope 8, along with the connecting ring 13, force sensor 11 and other components, can be separated from the frame 1 for easy individual storage.

[0033] 4. Rebuild When re-erecting the tent, first press the unlocking block 20 from the outside of the detection bracket 5. The unlocking block 20 moves inward, and the inclined surface 21 on the unlocking block 20 pushes through the edge of the unlocking hole 22 on the slider 17, thereby causing the slider 17 to move out of the locking hole 23. After the connecting rod 9 is unlocked, the pressure detection plate 6 automatically slides outward under the elastic force of the compressed spring 7 until it is in close contact with the junction of the canopy roof 3 and the side wall 4 of the fabric 2, restoring it to its initial working state. Then, align the mounting blocks 15 on the four connecting rings 13 and insert them into the corresponding mounting holes 14 on the frame 1 to complete the quick fixing of the tension detection rope 8. At this time, the push block 10 contacts the tension detection rope 8 again, the force sensor 11 starts to monitor the reference tension, and the device enters the standby monitoring mode.

[0034] The specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiments described above. For those skilled in the art, various changes, modifications, substitutions, and variations made to these embodiments without departing from the principles and ideas of the present invention should still fall within the protection scope of the present invention.
