Description

Technical Field

[0001] This utility model relates to the technical field of building exterior wall spraying devices, specifically to an adjustable water spraying device for building exterior walls. Background Technology

[0002] Since the 13th Five-Year Plan, the state has formulated relevant policies to promote the transformation of the construction industry into a prefabricated building industry, with the aim of vigorously developing prefabricated buildings. However, from the perspective of the overall development of the construction industry, whether it is the traditional construction method or the currently adopted prefabricated construction method, the phenomenon of leakage in exterior walls (windows) still exists. The relevant provisions of the current industry standard "Technical Specification for Waterproofing Engineering of Building Exterior Walls" JGJT235-2011 stipulate that after the waterproofing construction of building exterior walls is completed, a water spray test should be conducted after rain or for 30 minutes. The current industry standard "Technical Specification for On-site Testing of Building Waterproofing Engineering" JGJT299-2013 specifies relevant requirements for the distance between the water spray pipe and the exterior wall, the water pressure, the diameter of the water spray pipe, and the spacing between pipe holes when conducting water spray tests on building facades. The current industry standard "Technical Specification for Testing of Building Doors and Windows" (JGJT205-2010) stipulates that when the height or width of an exterior window is greater than 1500mm, its water tightness performance should be tested by on-site water spraying. The standard also specifies the water pressure, distance from the window / door surface, and spraying time at the testing location. Using rainy days for leakage inspection is currently the most basic method for water spraying tests on exterior walls (windows). However, it is clear that the effect of using rainy days for water spraying tests cannot meet the relevant requirements specified in the standard.

[0003] Currently, there is research on water spraying equipment and methods in the industry. For example, Chinese patent with publication number CN105486461A discloses a utility model patent entitled "Exterior Wall Water Spraying Test System and Test Method". Although it has water spraying pipelines and water pressure pumps, its spraying device is a single vertical pipe, which cannot form a water curtain with uniform pressure on the surface of the exterior window. Considering that there are more and more recessed window shapes on the exterior facades of modern buildings, and the diverse line designs of parapet wall eaves or the perimeter of exterior windows, the vertical pipe does not have the ability to form a continuous water curtain for the recessed windows according to the distance and water pressure required by the specifications. For example, Chinese patent CN106969883A discloses a utility model patent entitled "Exterior Wall Water Spray Test Device and Method for Conducting Water Spray Tests Using the Same." The device is a cantilevered support structure placed on the roof. A hand-cranked compass controls the spray pipes to descend to the eaves of the exterior wall. Although a limit structure controls the distance to the exterior wall (window), this device clearly requires manual operation. Furthermore, it is only suitable for spraying at the eaves and cannot detect the joints between exterior windows and exterior walls. Another example is Chinese patent CN117699074A, which discloses a utility model patent entitled "A Building Exterior Wall Water Spray Test Unmanned Aerial Vehicle." While this device has some intelligent control functions, it cannot meet the requirements for the spacing of the water spray pipe holes in the specifications, and it cannot achieve a uniform water curtain when spraying water onto exterior windows. For example, Chinese patent CN118603424A, a utility model patent, discloses a water spraying test device and method for building exterior walls. Although the device has limiting measures, it is not conducive to accurately adjusting the distance from the wall for exterior walls with recessed windows. It also lacks the function of adjusting the water spray holes, has poor mobility of the lifting frame, and has a low level of intelligent water spraying operation. Another example is Chinese patent CN119643407AA, a utility model patent, discloses a water spraying device and spraying method for building facades. Although this device has a winch as a power unit, multiple winches need to operate simultaneously for one building facade, making it impossible to achieve intelligent moving of the winches. Furthermore, the spray pipe cannot move forward or backward, making it impossible to spray recessed windows within the distance allowed by regulations, and it also cannot meet the pressure requirements for spraying exterior windows. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable water spraying device for building exterior walls. This device solves the technical problem in the prior art that exterior walls with structures such as recessed windows and convex windows cannot be sprayed with water at the specified pressure according to the design specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable water spraying device for building exterior walls includes a hanger assembly, a spraying assembly, and a control unit; The hanger assembly includes a movable support, a steel beam, a linear drive, a moving component, and a winch. The steel beam is fixedly mounted on the top of the movable support; the moving component is slidably mounted on the steel beam; the winch is fixedly mounted on the bottom of the moving component; and the linear drive is mounted on the steel beam for driving the horizontal movement of the moving component. The spray assembly includes a suspension frame and spray components. The suspension frame includes a suspension body, an auxiliary counterweight, a main lifting lug, and a limiting arc plate. The auxiliary counterweight is located on the outside of the suspension body, the main lifting lug is located on the top of the suspension body, and the limiting arc plate is located on the inside of the suspension body. The spray components include a horizontal water supply pipe, a vertical water supply pipe, and clamp-on nozzles. Multiple vertical water supply pipes are connected to the horizontal water supply pipe via tee fittings, and multiple clamp-on nozzles are installed on the vertical water supply pipes. The control unit consists of a ground control cabinet and a portable remote controller. The portable remote controller is used to control the linear drive and the winch. The ground control cabinet includes a cabinet body, a water pump, and an operation panel. The water pump pressurizes the ground water and sends it to the sprinkler system. The operation panel is located on the cabinet body.

[0006] Preferably, the movable support includes a base, side frames, wheels, counterweights, and diagonal support rods. Multiple wheels are disposed at the bottom of the base, two side frames are disposed on the top sides of the base, the diagonal support rods are diagonally supported on the side frames and the base, and the counterweights are disposed on the top of the base.

[0007] Preferably, the base includes a steel pipe frame, a first connecting ear plate and a second connecting ear plate. The first connecting ear plate is located at the top center of the steel pipe frame, and the two inclined support rods are connected to the first connecting ear plate. A second connecting ear plate is provided at each of the four corners of the top of the steel pipe frame, and the side frame is provided on two adjacent second connecting ear plates.

[0008] Preferably, the side frame includes two side rods arranged in a figure-eight shape, and multiple transverse connecting rods are provided between the two side rods.

[0009] Preferably, the movable component includes a bottom support plate, wheel side plates, guide wheels, and a traction component. Two wheel side plates are fixed at intervals on the bottom support plate, and two sets of guide wheels are arranged in parallel between the two wheel side plates. The traction component is fixedly installed at one end of the wheel side plates.

[0010] Preferably, the guide wheels are rotatably mounted on the wheel side plate; the interval between the two sets of guide wheels is adapted to the height of the steel beam; when the moving part moves horizontally, the two sets of guide wheels roll on the upper and lower surfaces of the steel beam respectively.

[0011] Preferably, the multiple water supply risers are fixedly connected by a fixed horizontal pipe; a ball valve switch is installed at the top of each water supply riser.

[0012] Preferably, the steel beam includes an H-beam and an end limiting plate, the end limiting plate being fixedly disposed at the end of the H-beam; a power box fixing plate is also disposed on the H-beam.

[0013] In this invention, the device achieves multi-dimensional position adjustment of the spray assembly in height, lateral direction, and longitudinal direction through a hanging bracket assembly. The winch precisely controls the height increase and decrease, the linear drive component drives the moving component to achieve lateral horizontal movement, and the movable bracket, together with the casters, completes the longitudinal movement. The three-way adjustment combination can adapt to the isosceles trapezoidal suspension bracket for recessed windows and linear shapes on exterior walls. It can achieve full coverage of the water spray range for exterior walls and windows of different sizes and shapes, completely solving the problem of incomplete coverage of irregular building structures by traditional water spray equipment, and ensuring that there are no dead angles in the water spray test.

[0014] The core components of the equipment adopt a modular design. For example, the steel beams are divided into multiple sections and connected by bolts. The water supply vertical pipes and fixed horizontal pipes in the sprinkler assembly are connected by snap-fit. The components of the hanger assembly are quickly assembled and disassembled using bolts. This design greatly simplifies the transportation, assembly, and dismantling process, reduces the manpower and time costs of roof and ground operations, and the modular structure facilitates individual maintenance and replacement of components, reducing the overall operation and maintenance costs of the equipment.

[0015] The control unit employs a dual control mode combining a ground control cabinet and a portable remote controller. The portable remote controller allows operators to control the raising, lowering, and lateral movement of the spray components from a distance, adjusting the working position in real time. The ground control cabinet centrally manages functions such as pump start / stop, water pressure adjustment, and parameter display (water pressure, running time, time alerts), and its casters at the bottom facilitate movement with the work area. This dual control system ensures safety during high-altitude operations while enhancing operational flexibility, allowing for rapid adjustment of spray parameters according to site requirements, ensuring a stable and controllable testing process.

[0016] The movable bracket in the hanger assembly is supported by diagonal bracing rods on the side frame and the base. The counterweight at the top of the base effectively balances the center of gravity of the equipment and prevents the equipment from tipping over when the spray assembly is suspended. An end limit plate is set at the cantilever end of the steel beam to prevent the moving parts from sliding beyond their travel range. The adjustable spacing of the guide wheels ensures that the moving parts slide stably on the steel beam.

[0017] Each water supply riser in the spray system is equipped with a flat ball valve at its top, allowing for individual control of the water outlet status of the corresponding riser based on the dimensions of the exterior wall or window, thus precisely adjusting the spray range. The ground control cabinet displays and adjusts the water pressure in real time, ensuring that the spray pressure meets the test standard requirements and preventing unstable water pressure from affecting the test results. The adjustable parameter design makes the equipment suitable for water spray test standards on different building exterior walls, improving the accuracy and reliability of test data and providing precise basis for testing the waterproof performance of building exterior walls.
