Description

Technical Field

[0002] In order to prevent cracks caused by temperature changes and shrinkage cracks caused by surface water loss, insulation boards made of polystyrene, polyurethane or rubber-plastic sponge are usually laid on the surface of the dam to protect the surface of the dam. This can effectively prevent the rapid evaporation of moisture caused by contact between concrete and air. At the same time, it has a good thermal insulation effect, prevents rapid changes in concrete temperature, and reduces the risk of dam cracking.

[0039] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0040] Please refer to Figures 1 to 9 , a leakage point detection and repair device under the dam thermal insulation and moisture retention layer, comprising: a dam 1, a detection component 3 and a repair component 9, the detection component 3 is fixed on the inclined surface of the dam 1, and the outer side of the detection component 3 is fixed with a thermal insulation board 2;

[0041] The detection assembly 3 includes a plurality of transverse partition tubes 31 fixed between the dam 1 and the insulation board 2, and a longitudinal partition tube 32 is fixed between the plurality of transverse partition tubes 31, and a plurality of maintenance openings 33 are opened on the side walls of the transverse partition tubes 31;

[0042] An inlet 301 is provided on the outside of the transverse partition tube 31, and an outlet 302 is provided below the inlet 301; a threaded telescopic rod assembly 8 is fixed on the outside of the maintenance opening 33, and the connecting pipe 6 is installed on the traveling assembly 4. When the traveling assembly 4 moves to the corresponding maintenance opening 33, the central axis of the connecting pipe 6 coincides with the central axis of the threaded telescopic rod assembly 8 on the maintenance opening 33;

[0043] A cleaning drill bit 7 is fixed to one end of the threaded telescopic rod assembly 8 away from the corresponding transverse dividing tube 31 , and a plurality of discharge holes 71 are provided through the bottom of the cleaning drill bit 7 .

[0044] First, the detection component 3, the threaded telescopic rod component 8 and the cleaning drill bit 7 are all pre-buried between the insulation board 2 and the dam 1, and fixed between the insulation board 2 and the dam 1 at equal intervals through multiple transverse partition tubes 31 and longitudinal partition tubes 32, so that the insulation board 2 is divided into a number of block spaces with smaller diameters. Since the material of the detection component 3 is a plastic material with a relatively high density, and both sides thereof are sealed and fixedly connected to the insulation board 2 and the dam 1, when an area is infiltrated, since the density of the detection component 3 is greater than that of the insulation board 2, the anti-infiltration ability can be improved and the length of the undercurrent under the insulation board 2 can be reduced. When water seepage occurs in the insulation board 2, the block area where the water seepage area is located can be directly repaired on the inner side of the insulation board 2;

[0045] Before use, the connecting pipe 6 and the repair component 9 are fixed on the walking component 4. The upper end diameter of the connecting pipe 6 is small. Then the walking component 4 is placed into the transverse partition pipe 31 from the inlet 301, and then moved along the transverse partition pipe 31 and the longitudinal partition pipe 32 to the outlet 302. The maintenance personnel control the walking component 4 to move to the maintenance port 33 above the water seepage area through the controller, and then drive the bottom of the connecting pipe 6 to insert into the threaded telescopic rod component 8 through the walking component 4, so that the connecting pipe 6 is engaged with the corresponding threaded telescopic rod component 8, and the walking component 4 drives the connecting pipe 6 to move to the maintenance port 33 above the water seepage area. The pipe 6, the threaded telescopic rod assembly 8 above the water seepage area and the cleaning drill bit 7 corresponding to the threaded telescopic rod assembly 8 rotate synchronously, and the threaded telescopic rod assembly 8 can drive the cleaning drill bit 7 to move to the side away from the maintenance port 33 when rotating. The connecting pipe 6 is sealed by the threaded telescopic rod assembly 8 and the cleaning drill bit 7, and a sealed flow channel is formed inside the threaded telescopic rod assembly 8 to facilitate the flow of polyurethane rigid foam. When the cleaning drill bit 7 is connected with the penetration area, a channel is formed between the cleaning drill bit 7 and the penetration area. The material of the insulation board 2 is polystyrene board, and the penetration cracks The surrounding insulation board 2 is soaked in water for a long time, which causes the material to soften and reduces its bearing capacity. The cleaning drill bit 7 can destroy and crush the softened material around the crack during drilling, which can not only clean the softened material around the crack but also form a channel for the injection of polyurethane rigid foam. The powder drilled by the cleaning drill bit 7 slides downward along the slope of the dam 1 under the influence of gravity and accumulates at the bottom of the channel. When the walking component 4 drives the connecting pipe 6 to reverse the threaded telescopic rod component 8 and the cleaning drill bit 7 corresponding to the threaded telescopic rod component 8 retracts inward to the initial state, the start The repair component 9 is moved to inject polyurethane rigid foam for repairing the insulation board 2 into the connecting pipe 6. The polyurethane rigid foam is sprayed out along the connecting pipe 6, the threaded telescopic rod component 8 and the discharge hole 71 of the cleaning drill bit 7 in sequence. The polyurethane rigid foam is injected into the channel, and the polyurethane rigid foam squeezes the powder drilled by the cleaning drill bit 7 while moving to the bottom of the channel, thereby compacting the powder drilled by the cleaning drill bit 7, thereby further improving the density in the insulation board 2 area, and the original water seepage cracks can be repaired by filling the cracks and channels with polyurethane rigid foam.

[0046] The cross-sections of the transverse partition tube 31 and the longitudinal partition tube 32 are both rectangular, and the outer sides of the plurality of maintenance ports 33 are fixed with fixing seats 34. Since the inclined surfaces of the dam 1 and the insulation board 2 are planes, the use of rectangular partition tubes can change the linear contact to the surface contact compared to the cylindrical partition tubes, thereby increasing the contact area and improving the stability of the fixing of the detection component 3;

[0047] The walking assembly 4 includes a support plate 41, a support rod 42, a connecting spring 43, a walking wheel 44 and a driving structure; multiple support rods 42 are rotatably connected to both ends of the support plate 41, and a baffle 421 is fixed between the multiple support rods 42, at least one connecting spring 43 is fixed on the side of the baffle 421 close to the support plate 41, and a walking wheel 44 is fixed on the end of the multiple support rods 42 away from the support plate 41, and a driving structure is fixed on the upper end of the support plate 41.

[0048] During use, when the connecting spring 43 is in its original length, the distance between the upper and lower walking wheels 44 is greater than the internal length of the transverse dividing tube 31. When the walking wheels 44 are placed in the transverse dividing tube 31, the baffle 421 must be pressed inward to compress the connecting spring 43, so that the multiple walking wheels 44 move inward. At this time, after the walking component 4 is placed in the detection component 3, the connecting spring 43 extends outward and recovers, and is driven by the elastic restoring force of the spring to move the baffle 421 away from the support plate 41, thereby driving the support rod 42 to rotate outward along the hinge with the support plate 41 until the walking wheels 44 contact the inner wall of the transverse dividing tube 31, so that the walking component 4 can move along the inner wall of the detection component 3, reducing the slippage of the walking wheels 44.

[0049] The driving structure includes a servo motor 11 and an electric telescopic rod 10. The servo motor 11 is penetrated through the upper end of the support plate 41, and the electric telescopic rod 10 is fixed to the outside of the servo motor 11. After the output end of the servo motor 11 is inserted into the small-diameter end of the connecting pipe 6, sealant is applied to the connection between the output end of the servo motor 11 and the connecting pipe 6, so that the upper end of the connecting pipe 6 is sealed and fixed to the output end of the servo motor 11. A positioning hole 411 penetrating the support plate 41 is provided on the inner side of the support plate 41, and the servo motor 11 is located on the inner side of the positioning hole 411. The moving path of the servo motor 11 is the same as the path of the positioning hole 411, and a camera 412 is embedded on the inner side of the support plate 41. The camera 412 is provided to facilitate maintenance personnel to observe and determine the position of the maintenance port 33, so as to facilitate the connection pipe 6 to be aligned with the threaded telescopic rod assembly 8 pre-buried in the insulation board 2.

[0050] When in use, the servo motor 11 is fixed in the positioning hole 411, and the output end of the servo motor 11 passes through the support plate 41 and is connected to the connecting pipe 6, and the moving path of the servo motor 11 is the same as the path of the positioning hole 411, so that when the walking assembly 4 moves to the working position, the servo motor 11 is driven by the electric telescopic rod 10 to move along the positioning hole 411 toward the direction close to the threaded telescopic rod assembly 8, so that the connecting pipe 6 and the threaded telescopic rod assembly 8 are engaged, thereby facilitating the connection.

[0051] A cross protrusion 61 is fixed to one end of the connecting tube 6 away from the servo motor 11, and a rectangular hole 62 is provided at the upper end of the cross protrusion 61 to penetrate the connecting tube 6. The interior of the connecting tube 6 is hollow, which is used to drive the threaded telescopic rod assembly 8 and provide a flow channel for the polyurethane rigid foam.

[0052] The threaded telescopic rod assembly 8 includes a hollow threaded column 81, a first threaded sleeve 82, a second threaded sleeve 83 and a third threaded sleeve 84. The first threaded sleeve 82 is slidably connected to the inner side of the fixed seat 34, and the inner side of the first threaded sleeve 82 is threadedly connected to the hollow threaded column 81, and the end of the hollow threaded column 81 close to the corresponding maintenance port 33 is provided with a groove 801 adapted to the cross protrusion 61, a telescopic sleeve 802 is fixed between the hollow threaded column 81 and the cleaning drill bit 7, and the inner side of the first threaded sleeve 82 is clamped with the second threaded sleeve 83, the outer side of the second threaded sleeve 83 is threadedly connected to the third threaded sleeve 84, and the inner and outer sides of the second threaded sleeve 83 are provided with threaded protrusions 831, and a plurality of guide grooves 803 are provided on the inner side of the threaded telescopic rod assembly 8, and the inner side of the guide groove 803 is slidably connected with a slider 804 adapted to the guide groove.

[0053] When the cross protrusion 61 on the connecting tube 6 is embedded in the groove 801 in the hollow threaded column 81, when the servo motor 11 drives the connecting tube 6 to rotate, the hollow threaded column 81 is driven to rotate synchronously. When the hollow threaded column 81 rotates, the first threaded sleeve 82 is driven to rotate through the thread. Since the slider 804 on the inner side of the fixing seat 34 is inserted into the guide groove 803 on the outer side of the first threaded sleeve 82, and since the fixing seat 34 is fixed on the outer side of the detection component 3, the first threaded sleeve 82 is guided and restricted in a straight line direction by the guide groove 803 and the slider 804, so that the first threaded sleeve 82 will not rotate and slide at the same time. Since the upper end face of the second threaded sleeve 83 is engaged with the upper end of the inner wall of the first threaded sleeve 82, when the first threaded sleeve 82 slides downward, it drives the second threaded sleeve 83, the third threaded sleeve 84 and the cleaning drill bit 7 to slide downward, and the thread on the outer side of the hollow threaded column 81 is engaged with the threaded protrusion 831 on the inner wall of the second threaded sleeve 83. When the hollow threaded column 81 rotates, the friction force is used to drive the second threaded sleeve 83 to rotate synchronously, and the threaded protrusion 831 on the outer wall of the second threaded sleeve 83 is meshed with the thread of the inner wall of the third threaded sleeve 84, and the third threaded sleeve 84 is restricted by the slider 804 and the guide groove 803, so that the third threaded sleeve 84 slides downward. At this time, since the telescopic sleeve 802 is fixedly connected to the hollow threaded column 81 and the cleaning drill bit 7, when the hollow threaded column 81 rotates, the cleaning drill bit 7 is driven to rotate synchronously. During the rotation of the cleaning drill bit 7, the insulation board 2 outside thereof is excavated, and during the rotation of the cleaning drill bit 7, the threaded telescopic rod assembly 8 is extended outward. Since the insulation board 2 is first divided into several blocks by the detection assembly 3, the space size of each block has been reduced. When the block corresponding to the penetration point is found, since the crack is usually in the shape of a long strip, it is easier for the cleaning drill bit 7 to drill into the crack during the drilling process. Compared with blind drilling, the damage to the insulation board 2 can be reduced.

[0054] By fixing the bearing seat 72 between the third threaded sleeve 84 and the cleaning drill bit 7, when the cleaning drill bit 7 rotates, the third threaded sleeve 84 slides downward, which can not only push the cleaning drill bit 7 to move downward, but also enable relative sliding between the third threaded sleeve 84 and the bearing seat 72 when the cleaning drill bit 7 rotates, thereby increasing the extension length of the threaded telescopic rod assembly 8 while reducing its volume.

[0055] The repair assembly 9 includes an annular hoop 91 and a hose 92, and the outer side of the connecting pipe 6 is coaxially rotatably mounted with the annular hoop 91, the side wall of the annular hoop 91 is penetrated with a through hole 901, and the outer side of the through hole 901 is threadedly connected with the hose 92, and the end of the hose 92 away from the through hole 901 is connected with a foam generator. When repair is needed, the foam generator is started. Since the two ends of the hose 92 are respectively connected to the foam generator and the annular hoop 91, the polyurethane hard foam generated by the foam generator is sprayed into the interlayer 903 along the hose 92, and then poured into the connecting pipe 6 through the rectangular hole 62, and then poured into the front end of the cleaning drill bit 7 along the connecting pipe 6, the hollow threaded column 81 and the telescopic sleeve 802 in turn, and then sprayed out through the discharge hole 71 at the bottom of the cleaning drill bit 7. The threaded telescopic rod assembly 8 can protect the flow path of the polyurethane hard foam, which is conducive to reducing the blockage of the flow path by dust after crushing. Since the discharge hole 71 is located on the inner wall of the cleaning drill bit 7, when the channel between the cleaning drill bit 7 and the crack is opened, the foam generator is sprayed into the interlayer 903 along the hose 92, and then poured into the connecting pipe 6 through the rectangular hole 62, and then poured into the front end of the cleaning drill bit 7 along the connecting pipe 6, the hollow threaded column 81 and the telescopic sleeve 802, and then sprayed out through the discharge hole 71 at the bottom of the cleaning drill bit 7. The threaded telescopic rod assembly 8 can protect the flow path of the polyurethane hard foam, which is conducive to reducing the blockage of the flow path by dust after crushing. Since the discharge hole 71 is located on the inner wall of the cleaning drill bit After the passage, the servo motor 11 rotates to drive the threaded telescopic rod assembly 8 to retract inward. At this time, the polyurethane rigid foam that has just moved into the telescopic sleeve 802 is affected by the centrifugal force and gravity of the rotation of the cleaning drill bit 7, so that it is quickly thrown out along the discharge hole 71, thereby increasing the filling speed, and because the throwing direction is the side of the cleaning drill bit 7 away from the fixed seat 34, the brushed polyurethane rigid foam is difficult to get stuck between the fixed seat 34 and the threaded telescopic rod assembly 8, so that it can be used multiple times, and the polyurethane rigid foam for repair is filled from the inside to between the insulation board 2 and the dam 1, so there is no need to replace the outermost insulation board 2, reducing the use of glue, which is beneficial to improving the sealing strength of the outermost layer of the insulation board 2.

[0056] A plurality of annular guide rails 902 are fixed to the inner side of the annular hoop 91, and an annular protrusion 63 adapted to the annular guide rails 902 is fixed to the outer wall of the connecting pipe 6, and a partition 903 is arranged between the annular hoop 91 and the connecting pipe 6, and the annular guide rails 902 and the annular protrusion 63 are arranged in a sealing manner.

[0057] The annular guide rail 902 on the inner side of the annular hoop 91 is inserted into the outer side of the annular protrusion 63. When the connecting pipe 6 rotates rapidly, the limit seat 5 circumferentially limits the annular hoop 91 and the hose 92, so that when the connecting pipe 6 rotates, the annular hoop 91 slides relative to the connecting pipe 6 through multiple annular guide rails 902 and the annular protrusion 63, thereby preventing the hose 92 from rotating with the connecting pipe 6 and being entangled on the outer side of the connecting pipe 6, causing the problem of poor circulation of the connecting pipe 6. At the same time, since the annular guide rail 902 and the annular protrusion 63 are sealed and matched, and a partition layer 903 is formed between the annular hoop 91 and the connecting pipe 6, when the through hole 901 and the rectangular hole 62 are not on the same axis, the polyurethane rigid foam can temporarily gather in the partition layer 903, and then flow in along the remaining rectangular holes 62, so as to reduce the situation where a large amount of polyurethane rigid foam gathers at the rectangular hole 62, resulting in blockage between the through hole 901 and the rectangular hole 62.

[0058] A limit seat 5 is fixed to the lower end surface of the support plate 41 , and a fixing hole 51 is formed inside the limit seat 5 . A pipe groove 413 is formed on the side wall of the support plate 41 , and a wire groove 441 corresponding to the pipe groove 413 is formed on the outer wall of the walking wheel 44 . The hose 92 passes through the tube groove 413 and the fixing hole 51 inside the limit seat 5, and the hose 92 is fixed by the tube groove 413 and the limit seat 5. Since the support plate 41 is located in the middle of the detection component 3 during the movement of the walking component 4, when the walking component 4 moves from the horizontal partition tube 31 to the longitudinal partition tube 32, the walking wheel 44 on one side of the support plate 41 drives the walking component 4 to move downward along the longitudinal partition tube 32. At this time, the hose 92 is bent at the end of the tube groove 413 and stuck in the wire groove 441 inside the walking wheel 44. When the walking component 4 leaves the longitudinal partition tube 32 and enters the transverse partition tube 31, the left side of the walking component 4 is changed to the right side of the walking component 4 as the front of the vehicle after moving to the lower transverse partition tube 31, so that the connecting pipe 6 is always located on the side of the support plate 41 close to the maintenance port 33.

[0059] The leakage point detection and repair device under the dam thermal insulation and moisture retention layer provided by the present invention is further explained below in conjunction with the accompanying drawings and implementation methods.

[0060] When in use, the detection component 3, the threaded telescopic rod component 8 and the cleaning drill bit 7 are all pre-buried between the insulation board 2 and the dam 1, and the surface of the dam 1 is divided into multiple block areas by a large number of transverse partition tubes 31 and longitudinal partition tubes 32; when a crack occurs in a certain area, the liquid is blocked outside by the detection component 3, so that it cannot flow to the adjacent area. At this time, the staff can directly observe the block where the crack is located from the outside of the dam 1, and then pass the hose 92 through the pipe groove 413 and the fixing hole 51 to connect it to the outside of the annular hoop 91, and then put the walking component 4 into the uppermost transverse partition tube 31 through the entrance 301. The walking component 4 drives the hose 92 to move inward through the walking wheel 44. When it moves to the top of the block where the crack is located, the maintenance personnel observe the position of the threaded telescopic rod component 8 through the camera 412 to make the position of the connecting pipe 6 consistent with the hollow threaded column 81. Corresponding to the position, the electric telescopic rod 10 is started to drive the servo motor 11 and the connecting pipe 6 to move downward until the cross protrusion 61 is engaged with the groove 801. At this time, the servo motor 11 is started, and the servo motor 11 drives the connecting pipe 6 and the hollow threaded column 81 to rotate synchronously, thereby driving the threaded telescopic rod assembly 8 and the cleaning drill bit 7 to drill downward until the output end of the cleaning drill bit 7 contacts the crack and forms a channel between the cleaning drill bit 7 and the crack. The servo motor 11 is started again to reverse, thereby driving the threaded telescopic rod assembly 8 to retract inward. At the same time, the cleaning drill bit 7 is reversed so that the polyurethane rigid foam entering the connecting pipe 6 and the telescopic sleeve 802 is thrown into the channel by the centrifugal force of the cleaning drill bit 7. Since the surface of the dam 1 is inclined, the polyurethane rigid foam is affected by gravity and gathers in the channel and cracks, and blocks the cracks, thereby repairing the penetration cracks from the inside of the insulation board 2.
