Description

Technical Field

[0001] The invention belongs to the technical field of engineering detection, and in particular relates to a window water seepage testing device for engineering supervision. Background Art

[0002] The window seepage test is a test used to detect the waterproof performance of the edge of the building's windows. It is usually carried out during construction or maintenance to ensure the sealing and waterproofness of the windows to prevent rainwater from penetrating into the room and causing damage or inconvenience. The window seepage test is very critical for building quality control. The existing technology extends the sprinkler equipment at a position higher than the height of the floor. Most of the sprinkler equipment uses PPR pipes, opens spray holes at appropriate positions, and sprays water according to the specified water pressure and flow rate. The duration is usually not less than 1 hour. During the sprinkling process, observe whether there is water seepage in the window. However, it is inconvenient to fix this sprinkler equipment when it is extended from a position higher than the floor of the building. At the same time, in order to prevent the spraying from causing a blind spot, it is usually necessary to adjust the spraying position many times to prevent the generation of a blind spot and avoid inaccurate test results.

[0003] A Chinese patent with authorization announcement number CN220356595U discloses a window water seepage test device for engineering supervision, including a spray assembly installed on the outside of the front end of a fixed pile and a mounting structure installed on the rear end of the fixed pile for fixing to the glass; the mounting structure includes: a circular fixing plate, the circular fixing plate is fixedly installed on the rear end of the fixed pile, a mounting frame is installed on the outside of the fixed pile, and fixing pipes are fixedly installed at the four corners of the mounting frame, and a vacuum suction cup is connected to the rear end of the fixing pipe.

[0004] The above patent uses a vacuum suction cup to fix the device on the outer wall of the window. The tester is required to take the device outside the window and adjust the four vacuum suction cups to a suitable spacing. When the window is high, it is more troublesome to fix it, and personnel may need to go to the upper floor to assist in fixing it. Summary of the invention

[0005] The purpose of the present invention is to provide a window water seepage testing device for project supervision, aiming to solve the problem that the fixing of the testing device in the prior art is troublesome and the device needs to be fixed on other floors.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a window water seepage testing device for engineering supervision, comprising a tightening assembly, a driving assembly for controlling the expansion of the tightening assembly, and two water spraying assemblies arranged on the front and rear surfaces of the tightening assembly, wherein the tightening assembly comprises a tightening portion, a clamping portion, a supporting portion and a connecting portion.

[0007] There are two tightening parts, which are symmetrically arranged at the center. The adjacent ends of the tightening parts are connected to each other through the clamping part. The connecting part is arranged at the other end of the tightening part. An installation groove is opened between the two side walls of the connecting part. The upper and lower walls of the installation groove are provided with circular holes, and the two circular holes are coaxially arranged.

[0008] The support part is arranged at the free end of the connecting part, and includes a support plate, a connecting plate and a rotating shaft. The rotating shafts are two vertically coaxially arranged and are rotatably connected to the two circular holes respectively. The support plate is arranged on the side wall of the rotating shaft through the connecting plate. The two support plates are symmetrically distributed on both sides of the connecting part.

[0009] The clamping part includes two connecting pieces and two sliding grooves. The two connecting pieces are fixedly mounted on one side of the end faces of the two tightening parts respectively. The two sliding grooves are respectively opened on the other side of the end faces of the two tightening parts. The connecting piece on one of the tightening parts is sleeved on the sliding groove on the other connecting piece.

[0010] The effect is that, through the driving component, the two pressing parts are moved away from each other so that they are pressed against the two diagonally opposite corners of the window, and at the same time the supporting part is spread open, and the supporting plate of the supporting part is pressed against the side wall of the window for reinforcement. Therefore, the test device of this scheme is simple to install, firmly fixed, and does not need to be installed on other floors. The installation of the spray detection mechanism can be realized on this floor.

[0011] The driving part includes a sleeve, a driving member, two lead screws, a piston, a hydraulic chamber, an ejector and a through hole. The hydraulic chamber is opened in the connecting part. The through hole is symmetrically opened with end faces at one end of the two tightening parts that are mutually sleeved and communicated with the hydraulic chamber. The two ends of the sleeve are respectively threadedly connected to one end of the two lead screws and installed in the through hole. The driving member is installed on the front side of the tightening part and is used to drive the sleeve to rotate. The piston is connected to the other end of the lead screw and extends into the hydraulic chamber. One end of the ejector contacts the connecting plate, and the other end extends into the hydraulic chamber and is slidably connected to the connecting part.

[0012] The effect is that the sleeve is rotated by the driving member, so that the screw first drives the tightening part for preliminary fixation, and then the supporting part is expanded for secondary fixed support, making the device fixing operation simple, and a single person can complete the device fixing and window water seepage test.

[0013] The side of the connection part away from the tightening part is an arc-shaped surface and is provided with a resistance part. The rear surface of the connection part is provided with an annular groove for installing a water spray assembly. The middle part of the inner wall of the annular groove near the resistance part is provided with a water inlet groove for supplying water to the water spray assembly.

[0014] The water spray assembly includes a water spray plate, a connecting part, a water inlet part and a hub motor. A connecting hole is opened between the front and rear surfaces of the connecting part. The water spray plate is sleeved in the annular groove through the connecting hole on the connecting part and is rotatably connected thereto. The hub motor is installed on the connecting part to drive the water spray plate to swing back and forth about the axis of the annular groove.

[0015] The water inlet part extends into the water inlet groove and is slidably connected thereto, a water inlet hole is provided on the rear surface of the connection part, the water inlet hole is communicated with one side of the water inlet groove, and a water inlet port is provided on one side of the water inlet part close to the water inlet groove.

[0016] The effect is that by driving the water spray plate to swing back and forth, the spray range of the device can be increased, avoiding the occurrence of spray dead corners in the spray equipment.

[0017] An air cavity is arranged inside the abutment part, a connecting hole is connected between the air cavity and the side of the water inlet groove away from the water inlet hole, a tightening piece is installed at one end of the abutment part away from the tightening part, one end of the tightening piece extends into the air cavity and is slidably connected with the abutment part.

[0018] The effect is that by setting a tightening member, the reciprocating swing during spraying is utilized to inflate the air cavity, thereby providing a second fixation for the test device, preventing it from loosening during spraying, causing the spray detection mechanism to fall off, and preventing accidents.

[0019] Two vent holes are arranged on the rear side surface of the connection part, a one-way valve for one-way air intake is arranged at the top outlet of one vent hole, and a pressure relief valve is arranged at the top outlet of the other vent hole.

[0020] The effect is that the one-way valve can ensure that the air cavity is inflated to prevent air leakage inside, which would cause the tightening part to be unable to perform secondary fixation on the test device. The pressure relief valve can prevent excessive pressure in the air cavity, which would affect the reciprocating swing during spraying.

[0021] Compared with the prior art, the present invention has the following beneficial effects: By driving the assembly, the two tightening parts are moved away from each other so that they are pressed against the two diagonally opposite corners of the window. At the same time, the supporting part is spread open and the supporting plate of the supporting part is pressed against the side wall of the window for reinforcement. Therefore, the test device of this scheme is simple to install and firmly fixed. It does not need to be installed on other floors. The spray detection mechanism can be installed on this floor. At the same time, by setting a tightening part and utilizing the reciprocating swing during spraying, the inside of the air cavity can be inflated, thereby fixing the test device for the second time to prevent loosening during spraying, causing the spray detection mechanism to fall off, and preventing accidents.

[0032] A water inlet groove 154 is provided on one side of the annular groove 153 near the abutment portion of the connecting portion 15. The water inlet groove 154 is an arc-shaped groove, one end of which is provided with a water inlet hole 154a. The water inlet hole 154a penetrates the connecting portion 15. The water inlet portion 33 is located on the clamping member 32 and extends into the water inlet groove 154 to be slidably connected thereto. A water inlet port 331 is provided on one side of the water inlet portion 33 near the water inlet hole 154a.

[0033] An air cavity 155 is provided inside the resistance part, and a tightening piece 156 with one end extending into the air cavity 155 is slidably installed on the resistance part of the connecting part 15.

[0034] The implementation principle of the embodiment of the present invention is as follows: when testing the water seepage of a window, the water supply pipe is connected to the water inlet hole 154a, and then the tightening assembly 1 is placed on the outside of the window glass so that the two connecting parts 15 installed thereon point to the two opposite angles of the window respectively, and then the sleeve 21 is driven to rotate by the driving member 22. Since the lead screw 23 is threadedly connected to the sleeve 21, as the sleeve 21 rotates, the lead screw 23 is pushed out of the sleeve 21, and at the same time, the lead screw 23 is fixedly connected to the piston 24 at one end of the hydraulic chamber 25, and is subjected to the resistance of the hydraulic oil in the hydraulic chamber 25, so that the lead screw 23 drives the two tightening parts 11 to move to the two opposite angles of the window respectively. When the tightening part 11 conflicts with the connecting part 15, as the lead screw 23 is pushed out, the piston 24 gradually moves to the hydraulic chamber 25. The hydraulic chamber 25 moves inside. At this time, the pressure inside the hydraulic chamber 25 increases, and the ejector 26 is pressed out of the hydraulic chamber 25, so that it moves toward the installation groove 151, and pushes the connecting plate 132 to rotate with the rotating shaft 133 as the axis. The connecting plate 132 drives the supporting plate 131 to rotate and finally presses against the side wall of the window sill to support the water spray test device. The water spray plate 31 is supplied with water through the water supply pipe, and the hub motor 34 is started to drive the water spray plate 31 to swing back and forth with the axis of the annular groove 153 as the axis. After the cleaning water enters the water inlet groove 154 through the water inlet hole 154a, it enters the water spray plate 31 through the water inlet port 331 and sprays the window. At the same time, with the reciprocating swing of the water spray plate 31, the water inlet part 33 slides back and forth in the water inlet groove 154, as shown in FIG. Fig.10 As shown, when the water inlet portion 33 slides clockwise along the water inlet groove 154, negative pressure is formed between the water inlet groove 154 and the connecting hole 154b, and the air in the air cavity 155 is sucked out through the connecting hole 154b, so that negative pressure is formed inside. At this time, the air cavity 155 sucks air through the one-way valve on the vent 155a. When the water inlet portion 33 slides counterclockwise along the water inlet groove 154, the gas between the water inlet groove 154 and the connecting hole 154b is pressed into the air cavity 155. At this time, the tightening member 156 is pushed out, so that it is tightened on the oblique angle of the window, thereby realizing secondary fixation of the window sill, preventing loosening during spraying, causing the spray detection mechanism to fall off, and thus preventing accidents.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
