Description

Technical Field

[0001] The invention relates to the technical field of construction engineering detection, and in particular to building exterior wall water seepage detection equipment. Background Art

[0002] The waterproof performance of the building's exterior wall is an important indicator of the building's quality. As the outermost barrier of the building, the building's exterior wall should have basic functions such as water blocking, moisture-proof, frost resistance and high temperature resistance. The building cannot be put into use immediately after construction is completed, and the building's exterior wall needs to be tested for water seepage.

[0003] In the prior art, for example, the patent document with publication number CN113484219A proposes a building exterior wall water seepage detection device for building construction projects, including: an adjusting structure, a water supply structure, a water collection structure, and a detection structure; the water supply structure and the water collection structure are both installed on the adjusting component; the adjusting structure is used to carry and adjust the positions of the water collection structure, the detection structure and the water supply structure; the water collection structure is used to recover the water flow sprayed onto the wall by the water supply structure; the detection structure is used to detect the degree of water seepage of the wall at different positions. This technical solution is achieved by arranging a water collecting box under the cover shell, and opening a water inlet trough in the cover shell to connect with the water collecting box. After the cover shell covers the wall, the sprayed liquid flows into the cover shell, and flows into the water collecting box through the water inlet trough, and then enters the water storage tank through the first hose, thereby recycling water resources.

[0004] However, the existing technical solutions still have limitations in actual use. The cover shell is attached to the wall for spraying, which is a more conventional way of spraying a limited area. The wall area covered by the cover shell can be accurately detected for water seepage. However, it may be affected by the flatness of the cover shell port and the flatness of the wall, resulting in a gap between the cover shell and the wall. If the above-mentioned water collection method of only opening a water inlet trough in the cover shell is still adopted, part of the liquid will flow out from the gap between the cover shell and the wall, thereby reducing the number of liquid cycles in the water seepage detection.

[0043] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0044] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

[0045] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Combine the following Figures 1 to 6 As shown, an embodiment of the present invention provides a building exterior wall water seepage detection device, comprising:

[0048] A base 1, wherein there is a storage space for storing liquid;

[0049] A vertical rail 2, which is arranged on the base 1 and distributed vertically;

[0050] A lifting platform 3 is slidably connected to the vertical rail 2 and can be lifted and lowered on the vertical rail 2;

[0051] A spray frame 4, which is arranged on one side of the lifting platform 3 and whose opening is used to abut against the wall;

[0052] A sprayer 5 is arranged inside the spray frame 4 and communicated with the storage space in the base 1, and is used to spray liquid toward the opening of the spray frame 4;

[0053] A water collecting assembly 6, which is arranged at the bottom end of the spray frame 4 and is used to collect the spray liquid inside the spray frame 4 and the liquid flowing down from the gap between the spray frame 4 and the wall;

[0054] The spray frame 4 is also provided with a hydraulic assembly 7, which is connected to the water collecting assembly 6. When the spray frame 4 is pressed against the wall, the hydraulic assembly 7 controls the water collecting assembly 6 to be pressed against the wall.

[0055] The present invention forms a covering area by attaching the spray frame 4 to the wall, and the sprinkler 5 performs water seepage detection on the covered wall area. During the process of the spray frame 4 attaching to the wall, the hydraulic component 7 together with the water collecting component 6 will slide toward the wall until it is attached. After the water collecting component 6 moves, a drainage outlet structure is formed inside the spray frame 4, and the water collecting component 6 can collect liquid flowing from the port of the spray frame 4 and the gap between the wall.

[0056] Among them, a motor 31 is installed on the lifting platform 3, and a transmission wheel 32 is sleeved on the output end of the motor 31. A vertically distributed transmission rack 33 is provided on the vertical rail 2. The transmission wheel 32 is transmission-connected with the transmission rack 33. The transmission rack 33 is fixedly connected to the vertical rail 2 and vertically distributed. The motor 31 drives the transmission wheel 32 to make the lifting platform 3 slide along the vertical rail 2. A slide seat 34 for installing a spray frame 4 is horizontally slidably connected to the lifting platform 3, and an electric push rod 35 for driving the slide seat 34 to slide is installed on the lifting platform 3.

[0057] Specifically, when controlling the spray frame 4 to fit the wall, it is necessary to first place the base 1 on the wall to be inspected, and then control the motor 31 to rotate together with the transmission wheel 32. Under the meshing transmission action of the transmission wheel 32 and the transmission rack 33, the height of the lifting platform 3 is controlled, and then the output end of the electric push rod 35 is controlled to extend so that the slide seat 34 slides toward the wall, so that the front port of the spray frame 4 fits the wall, and finally the sprayer 5 is controlled to suck the liquid in the storage space in the base 1 and spray it out (a conventional suction pump can be used, and the way the liquid is sprayed by the sprayer is not limited, only the front port coverage area of ​​the spray frame 4 needs to be covered).

[0058] Among them, mounting plates 41 are provided on both sides of the open end of the spray frame 4, a slide plate groove 42 is provided at the bottom end of the spray frame 4, a water collecting plate 43 is rotatably connected in the slide plate groove 42, an elastic support component 44 is provided on the inner side of the mounting plate 41, and the elastic support component 44 is used to elastically support the water collecting plate 43, and transversely distributed slide grooves 45 are provided on both sides of the spray frame 4, and when the water collecting plate 43 is in a horizontal state, its outer side is consistent with the inner side of the slide plate groove 42;

[0059] When the water collecting assembly 6 is in the initial position, the water collecting assembly 6 supports the bottom end of the water collecting plate 43 to keep the water collecting plate 43 in a horizontal state;

[0060] When the water collecting assembly 6 moves to the pressed wall, the elastic supporting assembly 44 can make the water collecting plate 43 in an inclined state to form a drainage outlet structure of the spray frame 4 .

[0061] Both sides of the water collecting plate 43 are provided with rotating shafts 431 to be rotatably connected to the inner side of the slide groove 42 , and both sides of the water collecting plate 43 are provided with vertically distributed side plates 432 , and both side plates 432 are in contact with the inner wall of the spray frame 4 .

[0062] The elastic support assembly 44 includes a bracket 441 fixedly connected to the inner side of the spray frame 4, a telescopic rod 442 is rotatably connected to the bracket 441, one end of the telescopic rod 442 is rotatably connected to the water collecting plate 43, a spring 443 is sleeved on the outer side of the telescopic rod 442, and both ends of the spring 443 are in contact with the bracket 441 and the water collecting plate 43 respectively.

[0063] Specifically, when the water collecting assembly 6 moves from the initial state to the state in contact with the wall, the water collecting plate 43 in the horizontal state is no longer supported by the water collecting assembly 6, and the elastic force released by the spring 443 causes the water collecting plate 43 to rotate to an inclined state. When the water collecting plate 43 is in the inclined state, it is supported by the water collecting assembly 6 again. At this time, the telescopic rod 442 of the elastic support assembly 44 is expanded to the maximum state, so that the inclined state of the water collecting plate 43 is locked.

[0064] At the same time, the rotation of the inclined water collecting plate 43 will cause one end of it to disengage from the slide groove 42, so that a drainage outlet structure for discharging the liquid in the spray frame 4 is formed at the bottom end of the spray frame 4 (i.e., the gap formed between one end of the inclined water collecting plate 43 and the spray frame 4). Most of the liquid continuously sprayed by the sprinkler 5 toward the wall covered by the spray frame 4 will flow into the interior of the spray frame 4 and flow into the water collecting assembly 6 below along the inclined water collecting plate 43.

[0065] Among them, the water collecting component 6 includes a water collecting frame 61, and two sliders 62 are provided on the inner side of the water collecting frame 61. The top ends of the two sliders 62 are respectively slidably connected in the two slide grooves 45, and the bottom ends of the two sliders 62 are used to jointly support the water collecting plate 43. The inner side of the water collecting frame 61 is connected with a guide plate 63. The water collecting frame 61 is provided with a drain pipe 64 connected to the storage space in the base 1. The bottom end of the inner side of the water collecting frame 61 is provided with a water baffle 65. Both ends of the water baffle 65 are connected to the inner wall of the water collecting frame 61, and the water baffle 65 is located at the port of the water collecting frame 61.

[0066] The guide plate 63 is an integral structure consisting of a straight plate portion 631 and an inclined plate portion 632, and both sides of the straight plate portion 631 and the inclined plate portion 632 are provided with evenly distributed water guide grooves 633, the outer side surface of the straight plate portion 631 is flush with the end surface of the water collecting frame 61, and both sides of the straight plate portion 631 are fixedly connected to the water collecting frame 61.

[0067] The area of ​​the slider 62 used to support the water collecting plate 43 is provided with a beveled surface 621. When the water collecting frame 61 is in contact with the wall, the water collecting plate 43 rotates to fit the beveled surface 621 and be consistent with the inclination angle of the beveled surface 621. When the water collecting frame 61 is in contact with the wall, the positions of the two sliders 62 are at the closest position to the wall. At this time, the water collecting plate 43 will rotate until it is fully in contact with the beveled surface 621 on the slider 62.

[0068] Specifically, most of the liquid sprayed by the sprinkler 5 will flow into the water collecting frame 61 from the water collecting plate 43 at the bottom of the spray frame 4, and a small part of the sprayed liquid will flow down along the wall from the gap between the spray frame 4 and the wall. The liquid flowing down along the wall is collected by setting a water collecting component 6, specifically, by setting a guide plate 63 on the inner side of the water collecting frame 61 near the port position, so that the liquid flowing down along the wall will first flow into the water diversion groove 633 on the inclined plate part 632 through the water diversion groove 633 on the straight plate part 631, until it falls into the water collecting frame 61 from the lower edge of the inclined plate part 632, and then flow back to the storage space of the base 1 through the drain pipe 64 set in the water collecting frame 61, thereby completing the circulation of the liquid.

[0069] Furthermore, an integrally formed vertical plate is provided at the end of the water collecting frame 61 away from the wall, and a water baffle 65 is provided at the end of the water collecting frame 61 close to the wall, so that a rectangular space capable of storing liquid is formed in the water collecting frame 61. In addition, the contact between the water baffle 65 and the wall can further reduce the liquid flowing out along the gap between the water collecting frame 61 and the wall.

[0070] The hydraulic assembly 7 includes a liquid storage box 71 mounted on the spray frame 4, two hydraulic damping rods 72 respectively mounted on two mounting plates 41, and two hydraulic push rods 73 respectively mounted in two slide grooves 45. The two hydraulic damping rods 72 are connected to the liquid storage box 71 through a first hose 74, and the two hydraulic push rods 73 are connected to the liquid storage box 71 through a second hose 75.

[0071] The output end of the hydraulic damping rod 72 passes through the corresponding sliding groove 45 , and the output end of the hydraulic push rod 73 is fixedly connected to the corresponding sliding block 62 .

[0072] Specifically, by installing hydraulic damping rods on two mounting plates 41 provided on the spray frame 4, in the process of controlling the spray frame 4 to fit against the wall, the output ends of the two hydraulic damping rods 72 will continue to retract, so that the hydraulic oil in the two hydraulic damping rods 72 will flow into the liquid storage box 71 through the first hose 74, and the excess hydraulic oil in the liquid storage box 71 will flow into the two hydraulic push rods 73 through the two second hoses 75, so that the output ends of the two hydraulic push rods 73 will extend, driving the two sliders 62 slidably connected in the slide groove 45 to move laterally, and finally making the water collecting frame 61 fit against the wall.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
