Description

Technical Field

[0001] The invention relates to the technical field of building seepage detection, and in particular to a building seepage detection device for construction engineering. Background Art

[0002] Building seepage detection is used to identify and locate moisture or liquid leakage problems in building structures so that they can be repaired in time to prevent further damage. Common methods include liquid dye detection, pressure testing, infrared thermal imaging, acoustic wave detection and vacuum testing. These methods can be used alone or in combination to improve the accuracy and reliability of detection.

[0003] After searching, the patent publication number is CN116124674A, which discloses a building seepage detection device for construction engineering, including a base plate and a support column. In the present invention, the water inside the gas transmission slot is squeezed into the position inside the squeeze plate through the second connecting pipe by a piston, and the water flows into the slot through the first connecting pipe to exert pressure on the pressure sensor, and the pressure number is read by the pressure sensor. By detecting the change in the pressure size of the pressure sensor for a certain period of time, it is determined whether there is seepage, which avoids the situation of observing seepage after the water tower is completely filled with water.

[0004] Although the above patent has certain beneficial effects, when the device is in use, the contact part between the extrusion block and the detection surface is only sealed by the deformation block. The seal of the deformation block may not completely cover all contact parts between the extrusion block and the detection surface, resulting in poor sealing effect and affecting the accuracy of the detection result. Different detection surfaces and extrusion blocks may have different shapes and surface conditions. Using only the deformation block may be difficult to adapt to all situations, reducing the versatility of the device.

[0005] To this end, we propose a building seepage detection device for construction engineering. Summary of the invention

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] 1. The present invention installs a vacuum generator, a storage tank, an air inlet and other devices.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely 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.

[0035] Reference Figure 1-6 A building seepage detection device for construction engineering includes a base 1, a turntable 2 is fixedly installed on the outer surface of one side of the base 1, and the detection angle can be adjusted by rotating the turntable 2. By adjusting the detection angle, different seepage sources or leakage points can be detected more accurately. A connecting rod 3 is fixedly installed on the outer surface of one end of the turntable 2 away from the contact with the base 1, and a vacuum generator 4 is fixedly connected to the end of the connecting rod 3 away from the turntable 2.

[0036] An air inlet 5 is installed through one side of the vacuum generator 4, and the vacuum generator 4 is connected to the air compressor through the air inlet 5. A fixture 16 is fixedly installed on the bottom of the vacuum generator 4, and the fixture 16 is connected through the sealing suction cup 20 through a pressurized pipe 17. An adsorption hard plate 21 is provided at the bottom of the sealing suction cup 20. An evacuation port 7 is opened at the bottom of the vacuum generator 4. The interior of the evacuation port 7 is connected to the sealing suction cup 20 through an air suction pipe 23. Through the set vacuum generator 4 and air compressor, the evacuation port 7 can generate suction through the air suction pipe 23, thereby vacuuming the sealing suction cup 20. Vacuuming can effectively draw away the air between the sealing suction cup 20 and the surface to be detected, forming a tighter seal, which reduces the possibility of air leakage, thereby improving the accuracy and reliability of detection.

[0037] A storage tank 9 is fixedly installed on the top of the vacuum generator 4. The outer surface of the storage tank 9 is covered with an insulation layer. The insulation layer can reduce heat conduction and prevent the carbon dioxide in the tank from gasifying. The storage tank 9 is used to store liquid carbon dioxide. An air outlet 6 is opened on the side of the vacuum generator 4 away from the air inlet 5. The air outlet 6 is provided to discharge the high-speed airflow generated when the vacuum generator 4 is in use, and an air outlet frame 8 is provided on the outside of the air outlet 6. The air outlet frame 8 is fixedly installed on the outer surface of one end of the vacuum generator 4 away from the turntable 2. A feeding pipe 10 is penetrated on the top of the air outlet frame 8, and the end of the feeding pipe 10 away from the air outlet frame 8 is connected with the storage tank 9. The high-speed airflow generated when the vacuum generator 4 is in use can spray the liquid carbon dioxide inside the storage tank 9 through the feeding pipe 10. The liquid carbon dioxide evaporates quickly after being sprayed, and cools the surrounding air, which can improve the sensitivity and accuracy of seepage detection and quickly reveal tiny leakage points. The effect of the airflow can also reduce environmental interference and Moreover, carbon dioxide is relatively safe and environmentally friendly, and the injection amount can be precisely controlled, thereby improving the detection effect and efficiency. An electrostatic generator 15 is also fixedly installed at the bottom of the vacuum generator 4. The top of the electrostatic generator 15 is connected to the air outlet frame 8 through the electrostatic tube 14. The electrostatic generator 15 can emit electric charges into the air outlet frame 8 through the electrostatic tube 14 to remove the static electricity in the air outlet frame 8. Removing the static electricity of the air outlet frame 8 can effectively reduce static electricity interference and ensure the cleanliness of the equipment surface, thereby improving the detection accuracy. Removing static electricity can also improve equipment performance, reduce failures, extend service life, and ensure operational safety. An exhaust pipe 22 is installed through the side of the air outlet frame 8 away from the vacuum generator 4. The end of the exhaust pipe 22 away from the air outlet frame 8 is connected to the adsorption hard plate 21 and extends to the bottom of the adsorption hard plate 21. The treated high-speed gas can be discharged from the bottom of the adsorption hard plate 21 through the exhaust pipe 22. The distance between the adsorption hard plate 21 and the surface to be measured is 1-2 mm.

[0038] The air outlet frame 8 is designed in a trumpet shape to reduce the air turbulence in the air outlet frame 8. The interior of the air outlet frame 8 is designed as a hollow sandwich. A plurality of partition plates 12 are arranged inside the air outlet frame 8. The partition plates 12 are made of aluminum alloy. The use of the partition plates 12 made of aluminum alloy not only reduces the weight of the ventilation system, improves the structural strength and durability, but also helps to improve the ventilation efficiency and system life. The partition plates 12 divide the interior of the air outlet frame 8 into a plurality of cavities 11. A plurality of ventilation holes 13 are provided on the surface of the partition plates 12. The interior of the air outlet frame 8 is filled with coolant to keep the air outlet frame 8 At the same time, due to the high density of the coolant, the propagation speed and energy of the sound waves will change. The coolant can absorb a part of the energy of the sound waves, convert it into heat or other forms of energy for consumption, and reduce noise. A water inlet pipe 18 is connected to one side of the pressurized pipe 17, and a pressure sensor 19 is fixedly installed inside the pressurized pipe 17. Water is added to the pressurized pipe 17 through the water inlet pipe 18. The water generates pressure on the pressure sensor 19, and the pressure number is read through the pressure sensor 19. The presence or absence of seepage is determined by detecting the change in the pressure of the pressure sensor 19 within a certain period of time.

[0039] In the present invention, when conducting seepage detection on a building, the sealing of the device is very critical, and the sealing of the device is directly related to the accuracy of the detection. The prior art does not utilize the high-speed airflow discharged by the vacuum generator 4 when evacuating the suction cup, which not only causes loud noise but also wastes energy. The present device processes the high-speed airflow discharged by the vacuum generator 4 and utilizes the Bernoulli principle to enhance the adsorption effect.

[0040] Move the device to the place where measurement is required, control the rotation of the turntable 2, select a suitable detection angle, clean the surface of the object to be measured, attach the sealing suction cup 20 to the area to be measured of the object, connect the air compressor to the vacuum generator 4 through the air inlet 5, start the air compressor and the vacuum generator 4, and use the vacuum port 7 to vacuum the inside of the sealing suction cup 20 through the suction pipe 23 to firmly adsorb the sealing suction cup 20 on the surface to be measured.

[0041] A high-speed airflow will be blown out from the air outlet 6, and the liquid carbon dioxide in the storage tank 9 will be sprayed out through the feeding pipe 10. The liquid carbon dioxide will quickly gasify to cool the air and mix with the air. At the same time, the electrostatic generator 15 will be started to emit charges into the air outlet frame 8 through the electrostatic tube 14 to remove the static electricity in the air outlet frame 8. Finally, the processed high-speed gas will be blown out from the bottom of the adsorption hard plate 21 through the exhaust pipe 22. The distance between the adsorption hard plate 21 and the surface to be measured is 1-2 mm.

[0042] When the high-speed flowing gas passes through the narrow channel between the adsorption hard plate 21 and the adsorption surface, according to the Bernoulli principle, the velocity of the fluid increases and the pressure decreases. In this way, the pressure inside the adsorption hard plate 21 will be lower than the external atmospheric pressure, thereby generating a pressure difference between the adsorption hard plate 21 and the adsorption surface. This pressure difference allows the adsorption hard plate 21 to adsorb the object without contacting the surface of the object, thus avoiding direct contact and scratching the surface of the object.

[0043] At the same time, since liquid carbon dioxide is used to cool the air, there are the following benefits. First, low-temperature gases usually have a larger density. For adsorption through the Bernoulli principle, this means that at the same flow rate, a larger pressure difference can be generated, thereby enhancing suction; second, low-temperature gases have a lower viscosity, which is conducive to the smooth flow of gas in the gap between the adsorption hard plate 21 and the adsorption object. Lower viscosity can reduce the resistance to gas flow, allowing the gas to reach the required flow rate faster and improve the adsorption effect; third, the molecular weight of carbon dioxide (about 44 g / mol) is larger than the average molecular weight of air (about 29 g / mol), so the density of the mixed gas will increase. According to Bernoulli's principle, under the same other conditions, an increase in gas density helps to increase adsorption.

[0044] Static electricity may be generated on the inner wall of the air outlet frame 8 during air flow, which will attract dust and tiny particles in the air, increase the roughness of the inner wall of the air outlet frame 8, and affect the wind speed of the exhaust air. Eliminating static electricity can reduce wind speed loss.

[0045] The trumpet-shaped design of the air outlet frame 8 can reduce the air turbulence in the air outlet frame 8, make the air flow more stable and orderly, and reduce the wind speed loss; the interior of the air outlet frame 8 is a hollow sandwich design, and the interior of the air outlet frame 8 is divided into multiple cavities 11 by a partition plate 12 with ventilation holes 13 in the middle. The interior of the air outlet frame 8 is filled with coolant to maintain the low temperature in the air outlet frame 8; due to the high density of the coolant, the propagation speed and energy of the sound wave will change. The coolant can absorb part of the energy of the sound wave, convert it into heat energy or other forms of energy to consume, and reduce noise.

[0046] After adsorption, water is added to the pressurized tube 17 through the water inlet pipe 18. The water generates pressure on the pressure sensor 19. The pressure number is read through the pressure sensor 19. The presence or absence of seepage is determined by detecting the change in the pressure of the pressure sensor 19 within a certain period of time.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
