Description

Technical Field

[0001] The present invention relates to the technical field of waterproof material detection, and in particular to a device and method for detecting performance of building waterproof materials. Background Art

[0002] Waterproof materials are the building envelope structures that must prevent the penetration of rainwater, snow and groundwater; they must prevent the erosion of moisture, steam and other harmful gases and liquids in the air. Common building waterproof materials include polymer coatings, asphalt and PVC waterproof membranes. Among many waterproof materials, PVC waterproof membranes are widely used in building waterproof projects in roofs, basements, bathrooms and other areas due to their unique properties and wide applicability. For waterproof materials, their leakage performance needs to be tested before use to ensure that they can meet the use standards.

[0003] According to the Chinese patent with the announcement number CN109060626B, a waterproof material leak detection device for engineering construction is disclosed. The invention can fix the material to be tested on the inner wall of the detection tube by setting a pressure device, and can add water and increase air pressure to it for leak detection. It has good adjustability and can detect multiple materials at the same time, with good comparison. According to the Chinese patent with the announcement number CN116908074B, an intelligent detection device and detection method for building waterproof materials are disclosed. The invention evenly arranges humidity sensors in an array on a humidity detection plate to detect the water seepage of waterproof materials. The value detected by the humidity sensor directly reflects the water seepage of the waterproof material, and the detection is more accurate and reliable. The above technical solution detects the anti-water seepage performance of the waterproof material by adding water and adding air pressure when in use. In this detection process, the performance of the waterproof material is judged either by collecting the seepage and observing the water volume, or by detecting the humidity generated by the seepage. When continuing to perform performance tests on other waterproof materials, the detection device will come into contact with the seepage generated by the previous group of waterproof materials through the detection component, which will cause inaccurate detection of subsequent other waterproof materials.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 15The present invention provides a technical solution: a building waterproof material performance testing device, comprising a testing box 1, a placing table 2 and a testing mechanism 6, wherein the placing table 2 is arranged in the middle of the testing box 1, a recovery tank 101 is installed at the bottom of the testing box 1, an electric push rod 102 is installed in the middle above the recovery tank 101, a support block 103 is installed at the top of the electric push rod 102, three groups of drainage covers 104 are installed on the outer side of the support block 103, a water collecting cylinder 3 plugged and installed with the placing table 2 is connected above the recovery tank 101, a cylinder 4 is installed on the top of the testing box 1, and a pressurizing component 5 is arranged on the lower side of the cylinder 4; An inner cavity is provided in the middle of the drainage cover 104, and a positioning tube 106 is fixed to the bottom surface of the inner cavity. A detection mechanism 6 is provided in the inner cavity of the drainage cover 104, and the detection mechanism 6 includes a shell a601 and a shell b602 connected by screws, and a drainage cavity 603 is provided in the middle of the shell a601 and the shell b602, and a humidity sensor 604 is also installed inside the shell a601 and the shell b602. An energy storage tube 606 is integrally formed on one side of the shell a601, and a latch 607 is fixed in the middle of the energy storage tube 606, and an annular groove is provided on the outer peripheral side of the bottom end of the latch 607, and an energy storage spring 608 is sleeved on the outer side of the latch 607. A sealing strip is bonded to the abutting surfaces of the shell a601 and the shell b602 to ensure that the shell a601 and the shell b602 have sufficient sealing when spliced ​​and assembled, and the size of the spliced ​​and assembled shell a601 and the shell b602 is consistent with the drainage cover 104. The inner cavity size in the middle part matches, after the outer shell a601 and the outer shell b602 are spliced ​​with screws, the outer shell a601 and the outer shell b602 are inserted into the inner cavity of the drainage cover 104, so that the outer shell a601 and the outer shell b602 can be stably docked in the drainage cover 104; the outer sides of the outer shell a601 and the outer shell b602 are sleeved with a buffer ring, when the outer shell a601 and the outer shell b602 are inserted into the inner cavity of the drainage cover 104, the buffer ring abuts against the inner cavity, which can prevent the water flow from entering the inner cavity and causing the defect of inaccurate detection by the detection mechanism 6, and can also increase the friction force of the outer shell a601 and the outer shell b602 installed in the inner cavity of the drainage cover 104, when the outer shell a601 and the outer shell b602 are reset and pushed by the energy storage spring 608, the speed of the detection mechanism 6 to export the drainage cover 104 can be slowed down through the extrusion contact between the buffer ring and the inner cavity of the drainage cover 104; The top of the drainage cover 104 is a concave structure, and the lower end of the concave part of the drainage cover 104 is connected to the reserved opening at the top of the drainage cavity 603. The upper side of the drainage cover 104 is connected with a drain plate 105. When the waterproof coiled material 9 leaks water downward, the water will pass through the pores on the surface of the drain plate 105 and flow into the drainage cavity 603 between the shell a601 and the shell b602 along the concave part of the drainage cover 104. At the same time, when the water flows in the drainage cavity 603, it will inevitably wet the test paper 605 and the sensing sheet of the humidity sensor 604 through the reserved opening. The test paper 605 reacts with the water flow to produce a color change to judge the position where the seepage water flows in the drainage cavity 603, and the humidity sensor 604 senses the humidity to judge the anti-water seepage performance of the waterproof coiled material 9. A drainage mechanism 7 is provided inside the water collecting tube 3, and the drainage mechanism 7 includes a fixed tube 701 integrally formed with the inner bottom wall of the water collecting tube 3, and a support plate 702 fixed to the lower side of the drainage cover 104 is inserted inside the fixed tube 701, and a flap 710 is movably connected to one side of the support plate 702, and an arc-shaped latch is provided on the upper surface of the flap 710, and a reset spring 711 is connected between the support plate 702 and the flap 710, and a waterproof membrane 9 is laid flat on the placement table 2; reserved openings are provided at the upper and lower ends of the drainage cavity 603, and the two reserved openings are staggered in the outer shell a601 and the outer shell b602, and induction sheets connected to the humidity sensor 604 are provided in the reserved openings at the upper and lower ends of the drainage cavity 603, and test papers 605 are provided on the upper and lower sides of the induction sheets.

[0021] In the specific implementation, first, the electric push rod 102 pushes the support block 103 and the drainage cover 104 upward and away from the upper opening of the water collecting tube 3. At this time, the drainage cover 104 will drive the bottom support plate 702 to move upward along the fixed pipe 701 to be discharged. When the electric push rod 102 controls the upward movement height of the drainage cover 104 so that the upper edge of the fixed pipe 701 abuts against the middle and lower position of the flap 710, the flap 710 will be closely attached to the side of the support plate 702 due to the restriction of the fixed pipe 701; Then, the assembled shell a601 and shell b602 are inserted along the upper opening of the inner cavity of the drainage cover 104, so that the latch 607 in the energy storage tube 606 is positioned and inserted into the positioning tube 106, and at the same time, the energy storage spring 608 outside the latch 607 abuts against the upper end of the positioning tube 106. At this time, by pressing the upper surfaces of the shell a601 and the shell b602, the shell a601 and the shell b602 are compressed and deformed between the energy storage tube 606 and the positioning tube 106 until the latch 607 is completely penetrated. The positioning tube 106 is positioned. At the same time, after the positioning tube 106 is led out, the bottom end of the latch 607 will squeeze the arc-shaped teeth on the upper edge of the flap 710, so that the upper end of the flap 710 will be elastically deflected when being squeezed, so that the annular groove at the bottom end of the latch 607 and the arc-shaped teeth on the upper edge of the flap 710 will be anti-loosely engaged, so that the upper surfaces of the shell a601 and the shell b602 can fit the inner concave surface of the drainage cover 104, and then the drain plate 105 is buckled on the drainage cover 104; Subsequently, when the electric push rod 102 pulls the support block 103 and the drainage cover 104 downward and docks with the upper opening of the water collecting tube 3, the upper surface of the support block 103 will be flush with the upper surface of the placing table 2. At this time, the support plate 702 is completely received in the fixed tube 701, and the top position of the flap 710 is limited by the upper edge of the fixed tube 701, so that the flap 710 loses the ability of elastic deflection, so that the flap 710 can completely lock the annular groove at the bottom end of the latch 607 through the arc-shaped teeth on the upper edge, ensuring that the detection mechanism 6 will not be accidentally ejected; Finally, when the detection mechanism 6 completes the anti-seepage performance test of the waterproof coiled material 9, the upward movement height of the drainage cover 104 is controlled by the electric push rod 102 to enable the flap 710 on the side of the support plate 702 to completely lead out of the fixed tube 701, and the flap 710 is pushed by the reset spring 711 to rotate the flap 710 away from the support plate 702. At this time, the arc-shaped tooth on the upper edge of the flap 710 will be disengaged from the annular groove at the bottom end of the latch 607. When the latch 607 loses its limit, the energy storage spring 608 in the energy storage tube 606 resets and extends to push the positioning tube 106 and the energy storage tube 606. Tube 606 allows the shell a601 and the shell b602 to automatically slide upward and out along the inner cavity of the drainage cover 104, making it convenient for the staff to quickly take out and replace the detection mechanism 6 from the drainage cover 104. By quickly replacing the detection mechanism 6, it is convenient for the detection box 1 to continue to perform anti-water seepage performance tests on other waterproof materials. By replacing the detection mechanism 6 every time the waterproof material is tested, it is prevented that the performance test of the previous waterproof material is inaccurate due to the test paper 605 and the sensing sheet of the humidity sensor 604 being wet during the performance test.

[0022] See also Figure 5 , Figure 7 as well as Figure 13-Figure 15A slide groove 703 is provided in the middle of the support plate 702, and the slide groove 703 is integrally composed of a narrow groove at the upper part and a wide groove at the lower part, and a rack 704 is provided on the side of the wide groove at the lower part of the slide groove 703; a flip gear 705 is inserted into the middle of the fixed tube 701 through a rotating shaft, and the outer side of the flip gear 705 is composed of an arc-shaped tooth surface, a right-angle limit portion and a horizontal fitting portion, and the edges on both sides of the horizontal fitting portion of the flip gear 705 are also rounded; deflection blocks 706 are installed at both ends of the rotating shaft of the flip gear 705, and the deflection blocks 706 are eccentrically connected to the rotating shaft; A traction arm 707 is movably connected between the two deflection blocks 706, and a pull rod 708 is rotatably connected to the lower end of the traction arm 707. One end of the pull rod 708 is rotatably connected to the outside of the fixed tube 701 through a rotating shaft, and a sealing plug 709 is fixed to one side of the pull rod 708. A leakage port that docks with the sealing plug 709 is opened at the bottom of the water collecting cylinder 3, and the water collecting cylinder 3 is connected to the recovery tank 101 through the leakage port at the bottom. A liquid level sensor is installed inside the water collecting cylinder 3, and the liquid level sensor is used to monitor the liquid level in the water collecting cylinder 3, so that the liquid level sensor transmits the liquid level to the monitoring terminal external to the performance detection device, which is convenient for the staff to judge the water seepage amount of the waterproof membrane 9 within the specified time.

[0023] In specific implementation, when the drainage cover 104 is inserted into the water collection tube 3 to test the waterproof membrane 9 for water seepage resistance, the support plate 702 is completely inserted into the fixed tube 701. At this time, the arc-shaped tooth surface of the flip gear 705 is set downward, and the right-angle limit portion of the flip gear 705 abuts against the upper corner of the narrow groove of the slide groove 703. At the same time, the horizontal fitting portion of the flip gear 705 fits against the inner wall of the narrow groove of the slide groove 703. When the electric push rod 102 drives the drainage cover 104 and the support plate 702 to move upward, the support plate 702 will produce a friction fit with the flip gear 705 through the slide groove 703. When the overturning gear 705 slides to the inside of the wide channel of the chute 703, the arc-shaped tooth surface of the overturning gear 705 will mesh with the rack 704. At this time, the upwardly moved support plate 702 will drive the overturning gear 705 to overturn in the wide channel of the chute 703, and the overturning gear 705 will drive the deflection block 706 to deflect and pull the traction arm 707 and the pull rod 708 when overturning, so that the pull rod 708 can drive the sealing plug 709 to be taken out from the water leakage port at the bottom of the water collecting barrel 3 when rotating, so as to facilitate the water collected in the water collecting barrel 3 to be sent to the recovery tank 101 for recycling; On the contrary, when the electric push rod 102 in the air drives the drainage cover 104 and the support plate 702 to move downward, the flipping gear 705 will drive the deflection block 706 to deflect and squeeze the traction arm 707 and the pull rod 708 when flipping in the reverse direction, so that the pull rod 708 can drive the sealing plug 709 to be inserted into the water leakage port at the bottom of the water collecting tube 3 to complete the sealing when rotating in the reverse direction.

[0024] See also Figure 1-Figure 4 as well as Fig.16 The pressurizing component 5 includes a mounting bracket 501 connected to the bottom of the cylinder 4, and three groups of conical water-blocking covers 502 are installed on the lower side of the mounting bracket 501. A sinking opening is provided on the inner wall edge of the top of the water collecting cylinder 3; an annular sealing member is provided on the bottom outer edge of the conical water-blocking cover 502; when the conical water-blocking cover 502 is pressed down to press against the waterproofing membrane 9, the waterproofing membrane 9 is pressed into the sinking opening at the top of the water collecting cylinder 3, and then the annular sealing member on the bottom outer edge of the conical water-blocking cover 502 presses against the waterproofing membrane 9 in contact with the edge of the sinking opening, ensuring that when water is injected between the waterproofing membrane 9 and the conical water-blocking cover 502, water can be prevented from seeping out to the outside of the conical water-blocking cover 502; A water pipe 503 is connected to the middle part of the inner side of the conical water-blocking cover 502, a rubber sleeve 504 is fixed to the inner wall of the conical water-blocking cover 502, and two groups of solenoid valves for controlling water source and gas delivery are respectively connected to the side surface of the upper end of the conical water-blocking cover 502 and the conical surface of the conical water-blocking cover 502; a water tank 8 is installed on the side of the placement table 2 close to the cylinder 4, an air compressor 801 is installed on the upper side of the water tank 8, and a gas hose is connected between the air compressor 801 and the solenoid valve for controlling gas delivery, and two water pumps 802 are symmetrically arranged inside the water tank 8, one of which is used to pump the water source in the water tank 8 into the conical water-blocking cover 502, and the other water pump 802 is used to pump the water source in the conical water-blocking cover 502 The residual water is pumped back into the water tank 8, and the two water pumps 802 are commonly connected to a three-way valve 803, and a water hose is connected between the end of the three-way valve 803 away from the water pump 802 and the solenoid valve that controls the water supply. The water pipe 503 is composed of a straight pipe at the top and a spiral pipe at the bottom. When the water hose guides the water source to the upper end of the conical water-blocking cover 502, the water source will be sent along the straight pipe and the spiral pipe of the water pipe 503 to the detection area formed by the conical water-blocking cover 502 and the waterproof membrane 9, and water will be injected through the spiral pipe, which will not cause the water source with water pressure to directly impact the waterproof membrane 9, and when the water source between the conical water-blocking cover 502 and the waterproof membrane 9 is subsequently discharged, it can be drawn out through the spiral pipe.

[0025] In a specific implementation, one of the groups of conical water-blocking covers 502 in the pressurizing assembly 5 is controlled to close the water supply solenoid valve and the air supply solenoid valve, and the detection station formed between the group of conical water-blocking covers 502 and the waterproof membrane 9 is used as a blank control group, and then the first water pump 802 is controlled to inject water into the other two groups of conical water-blocking covers 502, and the air compressor 801 is controlled to introduce pressurized air into one of the groups of conical water-blocking covers 502 injected with water, and the air generated by the air compressor 801 enters the conical water-blocking covers 502 along the air supply hose. The space formed by the water shield 502 and the rubber sleeve 504 is forced to deform and squeeze the water source inside the conical water shield 502 by continuously injecting air, so that the three groups of conical water shields 502 are divided into a blank control group, a water injection test group, and a water injection and pressure test group.
