Description

Technical Field

[0001] The present application relates to the technical field of wall leakage detection, and in particular to a wall leakage detection device for engineering supervision. Background Art

[0002] At present, the leakage of buildings not only directly affects the quality of construction projects, but also destroys the structure of construction projects and even endangers people's lives in serious cases.

[0003] In the related art, a wall leakage detection device includes a device body, a sampling chamber and a detection chamber are provided inside the device body, a negative pressure fan is provided in the sampling chamber, and a water absorbent is provided in the detection chamber. The detection personnel first place the device body at the detection point, and then make the sampling chamber face the wall, and then drive the negative pressure fan to collect the gas at the wall. The negative pressure fan introduces the gas into the detection chamber and is absorbed by the water absorbent. Whether the wall is leaking is judged by the amount of water absorbed by the water absorbent.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when inspecting a wall, the inspector needs to constantly move the position of the device body to inspect different positions on the wall in turn, which is inconvenient for the inspector to perform leakage detection on the wall, and thus needs to be improved. Summary of the invention

[0005] In order to facilitate inspection personnel to perform leakage inspection on walls, the present application provides a wall leakage detection device for project supervision.

[0006] The wall leakage detection device for engineering supervision provided in this application adopts the following technical solution:

[0009] By adopting the above technical solution, the inspector starts the inspection device, and the lifting assembly drives the inspection box to move back and forth between the translation mechanisms. At the same time, the two translation mechanisms move unidirectionally along the length direction of the guide rails, and the inspection box performs leakage detection on the wall, thereby realizing leakage detection of the wall between the two guide rails. There is no need for the inspector to repeatedly move the inspection device, which facilitates the inspector to perform leakage detection on the wall.

[0012] By adopting the above technical solution, the inspector starts the inspection device, the lifting assembly drives the inspection box to move back and forth between the two moving seats, the inspection box drives the synchronization assembly to move back and forth between the two moving seats, when the inspection box pushes one of the trigger assemblies, the synchronization assembly pushes the other trigger assembly, the trigger assembly drives the translation gear to rotate through the transmission assembly, the translation gear moves along the length direction of the translation rack, thereby driving the two moving seats to move along the length direction of the guide rail, to achieve leakage detection of the wall between the two guide rails, without the need for the inspector to repeatedly move the inspection device, which facilitates the inspector to perform leakage detection on the wall.

[0013] Optionally, the transmission assembly includes a transmission wheel, a driven wheel and a transmission rod, the transmission rod is rotatably arranged in the slide groove, the driven wheel is coaxially sleeved on the transmission rod, the driven wheel meshes with the translation gear, the transmission wheel is coaxially fixedly sleeved on the transmission rod, the transmission wheel is meshed with the trigger assembly for transmission, and a ratchet mechanism is arranged between the transmission rod and the driven wheel.

[0014] By adopting the above technical solution, when the trigger component drives the transmission wheel to rotate, the transmission wheel drives the transmission rod to rotate, and the transmission rod drives the translation gear to rotate through the ratchet mechanism, so that the moving seat moves along the length direction of the guide rail. When the transmission wheel rotates in the opposite direction, the transmission rod rotates in the opposite direction. Under the influence of the ratchet mechanism, the translation gear and the moving seat remain stationary, thereby realizing intermittent unidirectional movement of the moving seat, reducing the detection blind angle of the detection box, and facilitating leakage detection of the wall between the two guide rails.

[0015] Optionally, the trigger assembly includes a trigger plate, a trigger rack, a slide bar and a spring, one end of the slide bar penetrates the side wall of the movable seat toward the detection box and extends into the mounting groove, the other end of the slide bar faces the detection box and is fixedly connected to the trigger plate, the trigger plate is used for the detection box to push, the trigger rack is arranged on a side of the trigger plate facing the slide bar, and the trigger rack meshes with the transmission wheel;

[0016] A spring is sleeved on the slide bar, one end of the spring is connected to the trigger plate, and the other end of the spring is connected to the moving seat.

[0017] By adopting the above technical solution, when the detection box reciprocates between the two moving seats, the detection box drives the synchronous assembly to reciprocate between the two moving seats. When the detection box pushes one of the trigger plates, the synchronous assembly pushes the other trigger plate. The trigger plate moves along the axial direction of the slide rod and compresses the spring. At the same time, the trigger plate drives the trigger rack to move, and the trigger rack drives the transmission wheel to rotate, so that the movement of the moving seat is driven by the lifting of the detection box, which is beneficial to the leakage detection of the wall between the two guide rails.

[0019] By adopting the above technical solution, when the detection box reciprocates between the two moving seats, the detection box pulls the synchronization rope, and the synchronization rope drives the synchronization block to reciprocate between the two moving seats, and the detection box and the synchronization block always move in opposite directions. After adjusting the position of the synchronization block, when the detection box pushes one of the trigger plates, the synchronization block pushes the other trigger plate, thereby controlling the two moving seats to move simultaneously. There is no need for the detection box to be triggered one by one when it reciprocates, which is beneficial to improving the efficiency of leakage detection.

When one of the adjusting cylinders is rotated, the two synchronous wheels rotate synchronously under the action of the synchronous belt, so that the other adjusting cylinder rotates synchronously. After the adjustment is completed, the inspector tightens the bolt so that the two clamping plates clamp the synchronous belt, and the synchronous belt forms a locking effect on the two synchronous wheels, which makes it convenient for the inspector to adjust the length of the synchronous rope.

[0022] Optionally, an air duct, an air branch duct, a negative pressure fan and a blower are arranged in the detection box, a sampling slot is provided on the side wall of the detection box facing the wall, one end of the air duct is connected to the sampling slot, and the other end is connected to the air outlet end of the blower, one end of the air branch duct is connected to the air duct, and the other end is connected to the air inlet end of the negative pressure fan, two ventilation holes are opened through the inner wall of the detection box, the air inlet end of the blower is connected to one of the ventilation holes, and the air outlet end of the negative pressure fan is connected to the other ventilation hole;

[0024] By adopting the above technical solution, when the negative pressure fan starts, the blower stops, and at the same time, the lifting assembly stops the detection box from moving. The negative pressure fan draws air from the wall surface in the sampling slot through the air duct. At this time, the detection box is adsorbed on the wall, and the drawn air passes through the humidity sensor, which transmits the detection data to the mobile terminal. When the negative pressure fan stops, the blower starts to separate the detection box from the wall, and the lifting assembly drives the detection box to continue moving, so that the detection box can perform fixed-point detection of wall leakage when it moves back and forth, which is beneficial to improving the accuracy of the detection results.

[0025] Optionally, the lifting assembly includes a stepper motor and a lifting rope, the stepper motor is fixed on the moving seat with a higher height, one end of the lifting rope is connected to the output shaft of the stepper motor, and the other end is connected to the detection box.

[0026] By adopting the above technical solution, the stepper motor is started, and the intermittent movement of the detection box can be achieved through the stepper motor.

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] The present application embodiment discloses a wall leakage detection device for engineering supervision. Figure 1 and Figure 2 A wall leakage detection device for engineering supervision includes a pair of guide rails 1 detachably fixed on a wall 6. The guide rails 1 are arranged horizontally. When detecting the wall 6, the height difference between the guide rails 1 is adjusted according to the required detection range on the wall 6. A translation mechanism 2 is arranged on both guide rails 1. The translation mechanism 2 moves unidirectionally along the length direction of the guide rail 1, and the movement directions of the two translation mechanisms 2 are the same. A detection box 3 is arranged between the two translation mechanisms 2, and a lifting assembly 4 is connected between the detection box 3 and the translation mechanism 2 located above.

[0044] The inspector starts the lifting assembly 4, and the lifting assembly 4 drives the inspection box 3 to move back and forth between the translation mechanisms 2. At the same time, the two translation mechanisms 2 move unidirectionally along the length direction of the guide rail 1, and the inspection box 3 performs leakage detection on the wall 6, thereby realizing leakage detection of the wall 6 between the two guide rails 1. There is no need for the inspector to repeatedly move the detection device, which facilitates the inspector to perform leakage detection on the wall 6.

[0045] Reference Figure 1 and Figure 2 The translation mechanism 2 includes a moving seat 21, a translation gear 22, a translation rack 23, a transmission assembly 24, a trigger assembly 25 and a synchronization assembly 26. A slide groove 211 is provided through the side wall of the moving seat 21, and the moving seat 21 is slidably connected to the guide rail 1 through the slide groove 211. A translation rack 23 is fixed to the opposite side walls of the two guide rails 1, and the translation rack 23 extends to both ends of the guide rail 1 along the length direction of the guide rail 1. An installation groove 212 is provided in the moving seat 21, and the installation groove 212 is connected to the slide groove 211. The translation gear 22 is rotatably arranged on the groove wall of the installation groove 212, and the rotation axis of the translation gear 22 is perpendicular to the wall 6, and the translation gear 22 engages with the translation rack 23. Both ends of the guide rail 1 are fixedly connected with a fixed block 11, and the fixed block 11 can be detachably fixed to the wall 6 by cement nails. The fixed block 11 reduces the possibility of the moving seat 21 being separated from the guide rail 1.

[0046] Reference Figure 1 The lifting assembly 4 includes a stepper motor 41 and a lifting rope 42. In the embodiment of the present application, the stepper motor 41 is fixed to the top wall of the higher moving seat 21, and the output shaft of the stepper motor 41 is away from the wall 6. One end of the lifting rope 42 is fixed and wound around the output shaft of the stepper motor 41, and the other end is fixedly connected to the side wall of the detection box 3 away from the wall 6. When the stepper motor 41 is started, the intermittent movement of the detection box 3 can be achieved through the stepper motor 41, and the detection box 3 can be controlled to move the same distance each time. When the stepper motor 41 stops, the detection box 3 is stationary and detects the wall 6, which is conducive to improving the accuracy of the detection result.

[0047] Reference Figure 2 The transmission assembly 24 includes a transmission wheel 241 and a transmission rod 242. The transmission rod 242 is rotatably arranged in the installation groove 212. The transmission wheel 241 is fixedly sleeved on the transmission rod 242. A driven wheel 2431 is rotatably sleeved on the transmission rod 242. The driven wheel 2431 and the transmission rod 242 are connected through a ratchet mechanism 243, and the driven wheel 2431 meshes with the translation gear 22. Among them, the ratchet of the ratchet mechanism 243 is fixedly sleeved on the transmission rod 242, and the ratchet pawl of the ratchet mechanism 243 is rotatably arranged on the side of the driven wheel 2431 facing the transmission wheel 241. Figure 2 ,by Figure 2The direction shown is the standard. When the transmission wheel 241 rotates counterclockwise, the transmission rod 242 rotates counterclockwise. At this time, the pawl of the ratchet mechanism 243 is engaged with the tooth groove of the ratchet wheel of the ratchet mechanism 243. The transmission rod 242 drives the driven wheel 2431 to rotate counterclockwise through the ratchet mechanism 243, and the driven wheel 2431 drives the translation gear 22 to rotate clockwise, so that the translation gear 22 moves along the translation rack 23, and the translation gear 22 drives the moving seat 21 to slide along the guide rail 1; when the transmission wheel 241 rotates clockwise, the transmission rod 242 rotates clockwise. Due to the friction resistance between the guide rail 1 and the groove wall of the slide groove 211, the pawl of the ratchet mechanism 243 and the ratchet wheel produce a "slip" phenomenon, so that the translation gear 22 and the moving seat 21 remain stationary.

[0048] Reference Figure 2 The trigger assembly 25 includes a trigger plate 251, a trigger rack 252, a slide bar 253 and a spring 254. The axis of the slide bar 253 is arranged in the vertical direction. The trigger plate 251 is fixed to the top of the slide bar 253. The bottom end of the slide bar 253 penetrates the top wall of the moving seat 21 and is threadedly connected to the limit ring 255. The bottom wall of the trigger plate 251 is parallel to the top wall of the moving seat 21. The trigger rack 252 is fixed to the bottom wall of the trigger plate 251. The trigger rack 252 is arranged in the vertical direction, and the bottom end of the trigger rack 252 penetrates the top wall of the moving seat 21. The trigger rack 252 extends into the mounting groove 212 and engages the transmission wheel 241. The side walls of the two moving seats 21 facing away from the detection box 3 are provided with a clearance groove 219 for the trigger rack 252 to pass through.

[0049] When the trigger assembly 25 drives the transmission wheel 241 to rotate, the transmission wheel 241 drives the transmission rod 242 to rotate, and the transmission rod 242 drives the translation gear 22 to rotate through the ratchet mechanism 243, so that the mobile seat 21 moves along the length direction of the guide rail 1. When the transmission wheel 241 rotates in the opposite direction, the transmission rod 242 rotates in the opposite direction, and the ratchet pawl and ratchet of the ratchet mechanism 243 produce a "slip" phenomenon, so that the translation gear 22 and the mobile seat 21 remain stationary, and the intermittent unidirectional movement of the mobile seat 21 is realized, reducing the detection blind spot of the detection box 3, which is conducive to the leakage detection of the wall 6 between the two guide rails 1. The rotation of the limit ring 255 can adjust the maximum distance between the trigger plate 251 and the mobile seat 21, change the distance that the trigger rack 252 can move, and thus adjust the distance that the mobile seat 21 moves each time.

[0050] Reference Figure 3The synchronization component 26 includes a synchronization rope 261 and a synchronization block 262. One end of the synchronization rope 261 passes through the lower moving seat 21 and is connected to the detection box 3, and the other end passes through the synchronization block 262 and the upper moving seat 21 in turn and is connected to the detection box 3. When the detection box 3 moves, the detection box 3 drives the synchronization block 262 to move in the opposite direction; when the detection box 3 abuts against one of the trigger plates 251, the synchronization block 262 abuts against the other trigger plate 251, so that the two moving seats 21 are controlled to move simultaneously, and the detection box 3 does not need to be triggered one by one when it moves back and forth, which is conducive to improving the efficiency of leakage detection.

[0051] Reference Figure 3 and Figure 4 , a plurality of guide ropes 213 are connected between the two moving seats 21, and the guide ropes 213 sequentially penetrate the top wall and the bottom wall of the detection box 3. In the embodiment of the present application, the number of guide ropes 213 is set to one, and the opposite side walls of the two moving seats 21 are provided with adjustment grooves 218, and a fixed pulley 217 is fixed to the bottom of the upper adjustment groove 218, and the guide rope 213 is wound around the fixed pulley 217, and both ends of the guide rope 213 are connected to the moving seat 21 below, and both ends of the guide rope 213 penetrate the detection box 3, and the guide rope 213 forms a rotation limit for the detection box 3, which reduces the possibility of the detection box 3 rotating under the action of external force, reduces the possibility of the detection box 3 colliding, and improves the accuracy of the detection result.

[0052] Reference Figure 4 and Figure 5 , a receiving groove 214 is provided in the movable seat 21 below, and the two ends of the guide rope 213 penetrate the top wall of the movable seat 21 and extend into the receiving groove 214. A winding drum 215 is rotatably arranged in the receiving groove 214, and the rotation axis of the winding drum 215 is parallel to the moving direction of the movable seat 21. One end of the winding drum 215 penetrates the groove side wall of the receiving groove 214 and is integrally formed with a turning handle 2151, and the other end is provided with a spline hole 2152. A sliding hole 216 is provided through the side wall of the movable seat 21, and a spline shaft 2161 is adapted to penetrate the sliding hole 216, and the spline shaft 2161 is inserted into the spline hole 2152. Both ends of the guide rope 213 are fixed and wound on the winding drum 215. The inspector slides the spline shaft 2161 to disengage the spline shaft 2161 from the spline hole 2152, and then rotates the handle 2151. The handle 2151 drives the winding reel 215 to rotate, thereby adjusting the length of the guide rope 213 to match the height difference between the two guide rails 1, which makes it convenient for the inspector to adjust the length of the guide rope 213 and is conducive to detecting walls 6 of different heights.

[0053] Reference Figure 4, an air duct 35, an air duct branch 351, a negative pressure fan 36 and a blower 37 are fixed in the detection box 3, and a sampling slot 38 is provided on the side wall of the detection box 3 away from the trigger plate 251, and a sealing gasket 381 is provided around the slot of the sampling slot 38. One end of the air duct 35 is connected to the sampling slot 38, and the other end is connected to the air outlet of the blower 37. One end of the air duct branch 351 is connected to the middle of the air duct 35, and the other end is connected to the negative pressure fan 36. A humidity sensor 5 for signal connection to the mobile terminal is provided in the air duct 35, and the humidity sensor 5 is located between the sampling slot 38 and the air duct branch 351. Both the negative pressure fan 36 and the blower 37 are signal connected to the mobile terminal.

[0054] The inspector controls the periodic opening and closing of the negative pressure fan 36 and the blower 37 through the mobile terminal. When the negative pressure fan 36 starts, the blower 37 stops, and at the same time, the lifting component 4 stops the detection box 3 from moving. The negative pressure fan 36 extracts air from the wall surface in the sampling slot 38 through the air duct 35. At this time, the detection box 3 is adsorbed on the wall 6, and the extracted air passes through the humidity sensor 5, and the humidity sensor 5 transmits the detection data to the mobile terminal; when the negative pressure fan 36 stops, the blower 37 starts, so that the detection box 3 is separated from the wall 6, and the blower 37 stops, and the lifting component 4 drives the detection box 3 to continue to move, so that the detection box 3 can perform fixed-point detection of wall 6 leakage when it moves back and forth, which is beneficial to improving the accuracy of the detection results.

[0055] Reference Figure 6 Two ventilation holes 39 are provided on the side wall of the test box 3 away from the sealing pad 381. The exhaust end of the negative pressure fan 36 is connected to one of the ventilation holes 39, and the air inlet end of the blower 37 is connected to the other ventilation hole 39. The ventilation holes 39 allow the air extracted by the negative pressure fan 36 to be discharged from the test box 3 in time, reducing the impact on subsequent test results and improving the accuracy of the test results. The two ventilation holes 39 and one end of the air duct 35 connected to the sampling slot 38 are covered with a filter 391. The gravel and dust entering the test box 3 are reduced, which is conducive to protecting the negative pressure fan 36, the blower 37 and the humidity sensor 5.

[0056] Reference Figure 3 and Figure 4 , an adjusting wheel 2181 is fixed in each of the two adjusting slots 218, and the synchronous rope 261 is sequentially wound around the adjusting wheel 2181. Two adjusting cylinders 31 are rotatably arranged inside the detection box 3, and the rotation axis of the adjusting cylinder 31 is perpendicular to the wall 6. The upper end of the synchronous rope 261 passes through the top wall of the detection box 3 and is fixed and wound around one of the adjusting cylinders 31, and the lower end of the synchronous rope 261 passes through the bottom wall of the detection box 3 and is fixed and wound around the other adjusting cylinder 31.

[0057] Reference Figure 6The ends of the two adjustment cylinders 31 facing away from the wall 6 penetrate the side wall of the detection box 3 and are fixed with a synchronous wheel 32. The synchronous wheel 32 is coaxially arranged with the adjustment cylinder 31, and the two synchronous wheels 32 are driven by a synchronous belt 33. A handle 311 is coaxially fixed to one of the synchronous wheels 32, which is convenient for the staff to rotate the adjustment cylinder 31. Two clamping plates 34 are slidably arranged on the side wall of the detection box 3 toward the synchronous belt 33, and a bolt 341 is connected between the two clamping plates 34. When the bolt 341 is tightened, the two clamping plates 34 approach each other and clamp the synchronous belt 33. After the inspector loosens the bolt 341, he can rotate the adjusting cylinder 31 to adjust the length of the synchronous rope 261 to match the height difference between the two guide rails 1, which is beneficial for inspecting walls 6 of different heights. When one of the adjusting cylinders 31 is rotated, the two synchronous wheels 32 rotate synchronously under the action of the synchronous belt 33, so that the other adjusting cylinder 31 rotates synchronously. After the adjustment is completed, the inspector tightens the bolt 341 so that the two clamping plates 34 clamp the synchronous belt 33. The synchronous belt 33 forms a locking effect on the two synchronous wheels 32, which makes it convenient for the inspector to adjust the length of the synchronous rope 261.

[0058] The implementation principle of a wall leakage detection device for engineering supervision in an embodiment of the present application is as follows: the detection personnel slides the movable seat 21 to connect the guide rail 1, and then fixes the fixed block 11 to connect the guide rail 1, then loosens the bolt 341 and pulls the spline shaft 2161 out of the spline hole 2152, and then calculates the height difference between the two guide rails 1 according to the height of the wall 6 and the detection requirements, and adjusts the length of the guide rope 213 and the synchronization rope 261 to adapt to the height difference between the two guide rails 1, and then pushes the two movable seats 21 to one end of the guide rail 1 in the opposite direction of the movement of the movable seats 21, so that the movable seats 21 are against the fixed block 11, and then the two guide rails 1 are fixed to the wall 6, and the negative pressure fan 36 and the blower 37 are started through the control terminal, so that the negative pressure fan 36 and the blower 37 are periodically opened and closed, and the stepper motor 41 is started at the same time.

[0059] The stepper motor 41 controls the movement of the detection box 3 through the lifting rope 42, and the movement of the detection box 3 drives the synchronous block 262 to move. At the same time, the detection box 3 performs leakage detection on the wall 6, and the humidity sensor 5 transmits the detection data to the mobile terminal; when the detection box 3 pushes one of the trigger plates 251, the synchronous block 262 pushes the other trigger plate 251, and the trigger plate 251 moves along the axial direction of the sliding rod 253 and compresses the spring 254. At the same time, the trigger plate 251 drives the trigger rack 252 to move, and the trigger rack 252 drives the transmission wheel 241 to rotate; when the transmission wheel 241 drives the transmission rod 242 to rotate, the transmission rod 24 The ratchet mechanism 243 drives the translation gear 22 to rotate, so that the movable seat 21 moves along the length direction of the guide rail 1; when the detection box 3 is separated from the trigger plate 251, the spring 254 pushes the trigger plate 251 to move toward the detection box 3 to reset, and at this time, when the trigger rack 252 drives the transmission wheel 241 to rotate in the opposite direction, the transmission rod 242 rotates in the opposite direction, and the pawl and ratchet of the ratchet mechanism 243 produce a "slip" phenomenon, so that the translation gear 22 and the movable seat 21 remain stationary, so as to realize the leakage detection of the wall surface 6, without the need for the detection personnel to repeatedly move the detection device, which is convenient for the detection personnel to perform leakage detection on the wall surface 6.

[0060] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
