Description

Technical Field

[0001] This utility model belongs to the technical field of building engineering management equipment, and more specifically, it relates to a building exterior wall seepage testing device. Background Technology

[0002] In building construction management, water seepage in exterior walls can affect the structural safety of buildings and the indoor environment. Therefore, it is necessary to test their waterproof performance. The existing external wall seepage testing equipment is mainly a fixed spray system. The fixed spray system is a support frame built outside the building, with multiple sets of nozzles installed to simulate a natural rainfall environment. Typically, the exterior wall is sprayed continuously for 1-2 hours at a rainfall intensity of 80-150 mm / h. The wall surface is then observed for wet marks or water droplets. This equipment is used for overall waterproof performance testing of large-area exterior walls, which can comprehensively investigate potential water seepage hazards and ensure the waterproof quality of building exterior walls.

[0003] The existing application number is CN202420845994.6. This utility model discloses a building exterior wall seepage testing device, which relates to the technical field of seepage testing devices. It includes a rectangular frame, with a U-shaped frame at the upper end of the rectangular frame. The U-shaped frame can move back and forth in a horizontal linear motion. A folding plate is set inside the U-shaped frame, and a circular plate is set outside the U-shaped frame. The circular plate and the folding plate rotate synchronously. A limit rod is set on one side of the circular plate, and a spring is wrapped around the outside of the limit rod. The limit rod can move back and forth in a horizontal linear motion. A water supply pipe is set on the side of the folding plate, and several nozzles are set on the outside of the water supply pipe. A hose is set at the water inlet end of the water supply pipe, and a water pump is set at the water inlet end of the hose. The water pump inlet end is connected to external clean water. This utility model sprays a large area of ​​the exterior wall surface through the horizontal reciprocating motion of the nozzles on one side of the folding plate, which improves the testing effect. At the same time, the folding plate can be folded and stored for easy carrying and does not take up space.

[0004] Based on the above, existing external wall seepage testing devices mostly have fixed nozzles, which means that the nozzles can only spray water at fixed locations on the wall, making it difficult to simulate a real rainy environment and affecting the accuracy of the external wall seepage test. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a building exterior wall seepage testing device. This addresses the issue that existing exterior wall seepage testing devices often have fixed nozzles, limiting the nozzles to spraying water only at fixed locations on the wall surface. This makes it difficult to simulate a real rainy environment, thus affecting the accuracy of the exterior wall seepage test.

[0006] The purpose and effectiveness of this utility model's building exterior wall seepage testing device are achieved through the following specific technical means:

[0007] A building exterior wall seepage testing device includes a test vehicle, a water collection tank, moving wheels, a test support, test spray components, a dynamic testing mechanism, and a test installation mechanism.

Four sets of moving wheels are provided, each set being a swivel wheel with brakes, and each set is fixedly connected to the bottom of the test vehicle. The test support is positioned above the test vehicle. Multiple sets of test spray components are provided, each rotatably connected to the front of the test support. Each set of test spray components has two sets of nozzles, with one set of nozzles angled at the front end and the other set of nozzles coaxially positioned at the front end. The dynamic testing mechanism is located inside the test support. The test installation mechanism is located outside the test support.

[0008] Furthermore, the dynamic testing mechanism includes: a test connector and a test water pump; the test connector is fixedly connected above the test carrier; the test water pump is fixedly connected to the upper front end of the test vehicle body, the inlet pipe of the test water pump is connected to the interior of the water collection tank, and the outlet pipe of the test water pump is connected to the interior of the test connector.

[0009] Furthermore, the dynamic testing mechanism also includes: a test drive motor, a first drive gear, a second drive gear, and a rotary joint; the test drive motor is fixedly connected to the right side of the test support; multiple sets of the first drive gear are provided, each set being rotatably connected inside the test support and drivingly connected to the test drive motor; multiple sets of the second drive gear are provided, each set being coaxially fixedly connected to the rear end of the test water spray component and meshing with the first drive gear; multiple sets of the rotary joint are provided, each set being rotatably connected to the outside of the test water spray component and communicating with the nozzle structure of the test water spray component, with the upper ends of each set of rotary joints communicating with the interior of the test connector via flexible hoses.

[0010] Furthermore, the test installation mechanism includes: a mounting fastener, a mounting adjuster, and a mounting locking pin; two sets of mounting fasteners are provided, and the two sets of mounting fasteners are respectively fixedly connected to the upper left and right sides of the test carrier; two sets of mounting adjusters are provided, and both sets of mounting adjusters are provided with a socket structure, and the two sets of mounting adjusters are respectively slidably connected to the upper interior of the mounting fastener; the mounting locking pin is threadedly connected to the inner side of the mounting fastener, and the mounting locking pin is inserted into the socket of the mounting adjuster.

[0011] Furthermore, the test installation mechanism also includes: a clamping adjustment component and a clamping locking pin; the clamping adjustment component is provided in two sets, and the two sets of clamping adjustment components are slidably connected to the front end of the installation adjustment component, and both sets of clamping adjustment components are provided with several insertion holes; the clamping locking pin is threadedly connected to the upper part of the clamping adjustment component, and the lower end of the clamping locking pin is inserted into the insertion hole of the clamping adjustment component.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a dynamic testing mechanism. When the test water pump is activated, water from the collection tank is injected into the test connector. The water then enters the test spray nozzle through a rotary joint and is sprayed onto the wall. Simultaneously, the test drive motor is activated, driving the first drive gear to rotate. This rotation of the first drive gear drives the second drive gear, which in turn drives the test spray nozzle to rotate. This rotation of the test spray nozzle enables dynamic water spraying during external wall seepage testing, simulating a natural rainy environment, thus improving the realism of the seepage test and consequently increasing the accuracy of the external wall seepage performance test results.

[0015] This invention utilizes a test installation mechanism to attach two sets of clamping adjustment components to the inside of the window. Rotating the installation clamping components clamps the window. When clamping windows of different sizes, loosening the clamping locking pin allows for left-right adjustment of the clamping adjustment components. Once the desired length is achieved, tightening the clamping locking pin and then loosening the installation locking pin allows for up-down movement of the installation adjustment components, thus adjusting the height. This allows the entire seepage testing device to be installed on different windows, improving its applicability. Attached Figure Description
