Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coiled material detection, and more particularly to a waterproof detection device for building waterproof coiled materials. Background Art

[0002] In the field of construction engineering, the waterproof performance of waterproof membranes directly affects the durability and safety of buildings. Waterproof performance testing is an important link to ensure its quality. At present, the industry generally adopts the method of spraying clean water on the surface of waterproof membranes and then observing whether there is water seepage on the back of the membranes to judge the waterproof ability of waterproof membranes. This method is simple to operate and can preliminarily reflect the waterproof effect of waterproof membranes. However, in order to ensure the uniformity and comprehensiveness of spraying clean water on the waterproof membrane, the existing technology usually needs to increase the water spraying volume or adjust the nozzle angle, and increase the spraying time. However, such operations can easily cause clean water to splash and drip from the edge of the waterproof membrane to the back of the waterproof membrane. Once this happens, even if the waterproof membrane itself has good waterproof performance, water stains will appear on the back during testing, resulting in a misjudgment that the waterproof performance does not meet the standard. This not only affects the accuracy of the quality assessment of the waterproof membrane, but also causes qualified products to be mistakenly eliminated, increasing production costs and testing time costs, and cannot provide a reliable basis for the selection of waterproof materials for construction projects. In view of this, we propose a waterproof detection device for building waterproof membranes. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a bracket, a supporting plate, a high-pressure water pump, a protective plate, a water storage box, a water spray plate, a water spray hole, a support pipe, a slide groove, a limit rod, a slider, a spring, an extrusion rod and an extrusion wheel. The waterproof membrane is made into an inverted "V" shape through the inverted "V"-shaped support pipe. The water spray hole of the water spray plate sprays the inverted "V"-shaped bottom of the waterproof membrane. Clean water can fully contact the membrane and slide along it, avoiding splashing and dripping of clean water on the back to interfere with detection. The triangular drainage part on the top of the water spray plate cooperates with the inverted "V"-shaped water spray hole to make the clean water spray in a fan shape, increasing the contact uniformity.

The baffle is then used to block both sides of the waterproof membrane to prevent it from deflecting, thereby ensuring a stable detection process.

[0016] In the present invention, the air pump cooperates with the negative pressure hood to place the waterproof membrane inspection in a negative pressure environment, simulating more stringent usage scenarios and further increasing the accuracy of the inspection.

The motor drives the retractable disk to rotate, and the coordination between the meshing part and the meshing groove stably drives the retractable roller to rotate, thereby realizing continuous detection of the waterproof roll. The friction disk increases the damping force for the rotation of the extrusion wheel, so that the waterproof roll has a better winding effect and greatly improves the detection efficiency.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0021] like Figure 1-7 As shown, a waterproof detection device for building waterproof membrane comprises a bracket 1, an inner wall of the bracket 1 is fixedly connected with a support plate 2, the top of the support plate 2 is fixedly connected with a high-pressure water pump 3, a pair of protective plates 4 are fixedly connected with the top of the bracket 1, a detection channel is formed between the protective plates 4, a water storage box 5 is arranged in the detection channel, the outer walls on both sides of the water storage box 5 are respectively fixedly connected with the opposite side between the protective plates 4, the interior of the water storage box 5 is connected with the water inlet of the high-pressure water pump 3 through a pipe, a plurality of water spray plates 6 are fixedly connected to the bottom inner wall of the water storage box 5, the interior of the water spray plate 6 is hollow, and the outside of the water spray plate 6 is provided with a water spray hole 7 connected with the interior thereof, the interior of the water spray plate 6 is respectively connected with the water outlet of the high-pressure water pump 3 through a pipe, a pair of support pipes 8 are arranged inside the detection channel, and the two ends of the support pipe 8 are tilted and bent downward to form an inverted "V" shape structure.

[0022] Specifically, the waterproof membrane that needs to be tested for waterproofing is pulled out and passed through the support rods in the test channel in turn. The bracket 1 supports the high-pressure water pump 3 through the support plate 2. The high-pressure water pump 3 runs to draw out the clean water in the water storage box 5 and transport it to the water spray plate 6. The clean water entering the water spray plate 6 will then be discharged from the water spray hole 7. The support tube 8 with an inverted "V" structure will make the waterproof membrane into an inverted "V" shape when supporting the waterproof membrane, so that the water sprayed from the water spray hole 7 will spray on the inverted "V"-shaped bottom of the waterproof membrane, so that the clean water can slide along the waterproof membrane. At this time, the staff can observe the back of the waterproof membrane to determine whether the waterproof membrane is qualified. In this way, while preventing clean water from splashing and dripping on the back of the waterproof membrane, thereby affecting the test results, the clean water can fully contact the waterproof membrane, thereby further increasing the accuracy of the waterproof membrane testing.

[0023] Furthermore, a pair of mutually symmetrical slide grooves 9 are provided on the opposite sides of the protective plates 4, and a pair of limit rods 10 are fixedly connected to the inner walls of the slide grooves 9. The outer walls of the limit rods 10 are slidably connected to the sliders 11. The outer walls of the limit rods 10 are sleeved with springs 12, and the two ends of the springs 12 are respectively welded to the top of the slider 11 and the top inner wall of the slide groove 9. An extrusion rod 13 corresponding to the support tube 8 is provided inside the detection channel, and the two ends of the extrusion rod 13 are respectively fixedly connected to the opposite sides of the sliders 11, and the outer wall of the extrusion rod 13 is evenly rotated and connected to multiple extrusion wheels 14 made of rubber.

[0024] Specifically, the slide groove 9 opened between the protective plates 4 accommodates the slider 11, and the limit rod 10 in the slide groove 9 limits the slider 11, and the spring 12 relies on its own elastic force to push the slider 11, so that the slider 11 can be forced to drive the extrusion rod 13 to move toward the support tube 8, and a plurality of rubber extrusion wheels 14 are rotatably connected to the extrusion rod 13. The extrusion rod 13 drives the extrusion wheel 14 to move toward the support tube 8 to clamp the waterproof membrane, so that the waterproof membrane can fully fit the support tube 8, thereby ensuring that the waterproof membrane always presents an inverted "V" shape during the inspection process, thereby increasing the stability of the waterproof membrane during waterproof inspection. At the same time, the extrusion wheel 14 is rotatably connected to the extrusion rod 13. The extrusion wheel 14 itself can rotate due to the friction generated with it when the waterproof membrane moves, thereby not affecting the movement of the waterproof membrane.

[0025] Furthermore, a pair of support rods 15 are provided in the detection channel, and the two ends of the support rods 15 are fixedly connected to the opposite sides of the protective plate 4 respectively. The top of the support rods 15 is fixedly connected to the air pump 16, and the bottom of the support rods 15 is fixedly connected to the negative pressure cover 17. The interior of the negative pressure cover 17 is connected to the air inlet of the air pump 16. The two sides of the negative pressure cover 17 are tilted and bent downward to form an inverted "V" structure corresponding to the support tube 8. The bent inner wall of the negative pressure cover 17 is rotatably connected to a plurality of symmetrically arranged baffle rods 18, and the negative pressure cover 17 is located between the support tubes 8.

[0026] Specifically, a support rod 15 is provided inside the detection channel, which supports the air pump 16 and the negative pressure cover 17. When the air pump 16 is running, air will be extracted from the inside of the negative pressure cover 17, and the two sides of the negative pressure cover 17 are tilted and bent downward to form an inverted "V" shape structure corresponding to the support tube 8. This allows the bottom of the negative pressure cover 17 to correspond to the waterproof membrane, so that the waterproof membrane fits with the baffle 18 on the inner wall of the negative pressure cover 17. When the gas inside the negative pressure cover 17 is extracted, negative pressure will be generated inside the negative pressure cover 17, so that the detection of the waterproof membrane is in a negative pressure environment, thereby further increasing the accuracy of waterproof detection of the waterproof membrane, and the baffle 18 is rotatably connected to the inside of the negative pressure cover 17, so the baffle 18 itself can rotate, so that the waterproof membrane can be driven to rotate by the friction generated between the baffle 18 and the baffle 18 when it moves, thereby preventing the operation of the negative pressure cover 17 from affecting the movement of the waterproof membrane.

[0027] Furthermore, a triangular drainage portion 19 is formed on the top of the water spray plate 6, and the water spray hole 7 is opened on the outer wall of the drainage portion 19, and the water spray hole 7 forms an inverted "V" structure corresponding to the support tube 8. The top of the drainage portion 19 is fixedly connected to a water collecting plate 33, and the top of the water collecting plate 33 is provided with a water collecting channel 34 passing through it, and the water collecting channel 34 is directly above the water spray hole 7.

[0028] Specifically, the triangular drainage portion 19 formed on the top of the water spray plate 6 requires clean water to pass through the drainage portion 19 before being discharged through the water spray hole 7, and the water spray hole 7 forms an inverted "V"-shaped structure corresponding to the support pipe 8, which makes the clean water spray in a fan shape when it is discharged from the water spray hole 7, thereby further increasing the uniformity and comprehensiveness of the clean water when it contacts the waterproof membrane, thereby further increasing the accuracy of waterproof testing of the waterproof membrane, and a water collecting plate 33 is fixedly connected to the top of the drainage portion 19, and a water collecting channel 34 is opened on the water collecting plate 33, and the water collecting channel 34 is located directly above the water spray hole 7. This allows the water discharged from the spray hole 7 to enter the water collection channel 34, and when the waterproof membrane moves, its bottom will contact the top of the water collection plate 33. When the water flows into the water collection channel 34 to spray the bottom of the waterproof membrane, the water will splash, and the inner wall of the water collection channel 34 will block the splashing water, increasing the effect of water contacting the bottom of the waterproof membrane. As the water continues to enter the water collection channel 34, the inner wall of the water collection channel 34 will temporarily "wrap" the water, so that the water fully contacts the bottom of the waterproof membrane in the water collection channel 34, thereby further increasing the accuracy of the waterproof membrane inspection.

[0029] Furthermore, the outer walls of both sides of the water spray hole 7 are hinged with torsion bars 20 through torsion springs, and the outer walls of the torsion bars 20 are fixedly connected with torsion plates 21, and the other ends of the torsion plates 21 on the same side are close to each other to cover the water spray hole 7.

[0030] Specifically, when the clean water enters the inverted "V"-shaped water spray hole 7, in order to prevent the clean water from being discharged directly from the inclined sides of the water spray hole 7 and unable to reach the top of the water spray hole 7 for fan-shaped spraying, the twisting plate 21 covers both sides of the water spray hole 7. When the clean water enters the water spray hole 7, it will begin to gather, and then fill the water spray hole 7 and then be discharged from the top. In this process, the clean water that enters the water spray hole 7 can only be discharged from the top of the water spray hole 7, so that the water in the water spray hole 7 cannot be discharged in time, thereby causing the water pressure in the water spray hole 7 to gradually increase. At this time, the clean water will push the twisting plate 21, making The twisting plate 21 drives the torsion bar 20 to start twisting, so that the two sides of the water spray hole 7 are no longer covered, so that the clean water is sprayed in a fan shape from the water spray hole 7. According to the definition of a narrow tube, the flow rate of the air flow will accelerate when it passes through a narrow area from a wide area. Similarly, the same is true for water. When clean water with different pressures passes through and pushes the twisting plate 21, the torsion angle of the twisting plate 21 will change with the pressure of the clean water. By changing the torsion angle of the twisting plate 21, the water pressure of the clean water passing through the twisting plate 21 is changed, so that the clean water always impacts the waterproof membrane with a stable pressure, thereby increasing the effect of waterproof testing of the waterproof membrane.

[0031] Furthermore, the upper side of the support tube 8 contracts downward to form a planar fitting portion 22 , both sides of the fitting portion 22 are arc-shaped structures, and the outer wall of the extrusion wheel 14 abuts against the outer wall of the fitting portion 22 .

[0032] Specifically, the fitting portion 22 formed on the upper side of the support tube 8 can increase the smoothness between the two when in contact with the bottom of the waterproof membrane, ensuring the normal movement of the waterproof membrane, and the fitting portion 22 provides sufficient contact surface for the extrusion wheel 14 to extrude the waterproof membrane, thereby ensuring the limiting effect of the waterproof membrane.

[0033] Furthermore, both sides of the protective plate 4 are fixedly connected with mutually symmetrical plate ears 23, the inner walls of the plate ears 23 are rotatably connected with the retractable disk 24, the outer walls of the plate ears 23 are fixedly connected with the motor 25, the main shaft of the motor 25 is fixedly and synchronously rotated with the retractable disk 24, and a plate groove 26 is opened in the center of the retractable disk 24, and a retractable roller 27 is inserted into the plate groove 26.

[0034] Specifically, the plate ears 23 on both sides of the protective plate 4 support the reel 24, by winding the waterproof membrane around the reel 27, and then inserting one end of the reel 27 into the plate groove 26 on one side of the reel 24, and then inserting the other end of the reel 27 into the other plate groove 26 of the reel 24, and then pulling the waterproof membrane through the support tube 8 and then winding it around the other reel 27. By running the motor 25, the motor 25 can drive the reel 24 to rotate, and the reel 24 is driven to rotate by the friction between the reel and the reel 27, and then the reel 27 rotates to wind the waterproof membrane, so that the waterproof membrane passes through the support tube 8 in turn, thereby realizing continuous detection of the waterproof membrane and increasing detection efficiency.

[0035] Furthermore, the outer wall of the extrusion rod 13 is fixedly connected with multiple friction discs 28 corresponding to the extrusion wheel 14. The outer wall of the friction disc 28 is provided with a friction hole 29. The outer wall of the extrusion wheel 14 is inserted into the friction hole 29 and fits with its inner wall, and the friction disc 28 is supported by rubber material.

[0036] Specifically, by setting the friction disc 28, the friction disc 28 fits with the outer wall of the extrusion wheel 14 through the friction hole 29, so that the friction force between the extrusion wheel 14 and the friction hole 29 increases the damping force for the rotation of the extrusion wheel 14, so that when the reel-up roller 27 pulls the waterproof membrane to move, the waterproof membrane is subjected to a certain pulling force, thereby increasing the winding effect of the waterproof membrane when winding.

[0037] Furthermore, a plurality of engagement grooves 30 are formed at the end of the reel 27 , and the inner wall of the plate groove 26 extends inward to form an engagement portion 31 corresponding to the engagement groove 30 , and the engagement portion 31 is inserted into the engagement groove 30 .

[0038] Specifically, by providing the engagement groove 30 and the engagement portion 31 to engage, the retractable disk 24 drives the retractable roller 27 to rotate through the engagement portion 31 and the engagement groove 30, thereby ensuring the stability of the retractable disk 24 when driving the retractable roller 27 to rotate.

[0039] Furthermore, the outer wall of the fitting portion 22 formed on the top of the support tube 8 is fixedly connected with symmetrically arranged baffles 32 , and the baffles 32 are respectively located on both sides of the extrusion wheel 14 .

[0040] Specifically, the baffle 32 is provided so that the baffle 32 blocks both sides of the waterproof roll, thereby increasing the stability of the waterproof roll when it is moved for continuous testing.

[0041] Working principle: This embodiment provides a waterproof detection device for building waterproof membranes. The waterproof membranes that need to be waterproofed are pulled out and passed through the support rods in the detection channel in turn. The bracket 1 supports the high-pressure water pump 3 through the support plate 2. The high-pressure water pump 3 runs to draw out the clean water in the water storage box 5 and transport it to the water spray plate 6. The clean water entering the water spray plate 6 will then be discharged from the water spray hole 7. The support tube 8 of the inverted "V" structure will make the waterproof membrane into an inverted "V" shape when supporting the waterproof membrane, so that the water sprayed from the water spray hole 7 will spray towards the inverted "V"-shaped bottom of the waterproof membrane, so that the clean water can slide along the waterproof membrane. At this time, the staff can observe the back of the waterproof membrane to determine whether the waterproof membrane is qualified. In this way, while preventing clean water from splashing and dripping on the back of the waterproof membrane, thereby affecting the detection result, the clean water can fully contact the waterproof membrane, thereby further increasing the accuracy of the waterproof membrane detection.

[0042] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
