Description

Technical Field

[0001] This utility model belongs to the field of wall spray testing technology, and in particular relates to an indoor wall spray testing device. Background Technology

[0002] Waterproofing testing of building structures, such as testing the waterproofing of walls, is a crucial part of the overall structural integrity assessment. This is especially important for areas that experience water use, such as bathrooms, which often serve as shower areas and require particularly high levels of waterproofing. This includes waterproofing the floor and walls. Wall waterproofing is particularly critical, as large amounts of water sprayed during showers can easily seep through the concrete structure into the ground.

[0003] Therefore, it is necessary to conduct a waterproof test on the wall structure of the bathroom. Since the wall structure of the bathroom is mostly four walls, a spray test needs to be conducted on each wall during the test. After spraying water at a certain spray pressure onto the wall for a period of time, check whether there is any penetration or dampness (on the exterior wall surface) through the wall.

[0004] The current testing method involves operators using a spray pipe to spray a specific area of ​​a single wall. During the test, after spraying a certain area of ​​the wall for a period of time, the spray pipe is adjusted (the spray direction is changed) to switch to another spray point, thereby testing whether the wall can withstand a certain spray water pressure.

[0005] However, this method is very inefficient in actual testing. The reason is that, firstly, indoor building structures such as bathrooms often have four walls, and testing each wall individually is very inefficient. Even if multiple nozzles are used for simultaneous testing, the following drawbacks still exist:

[0006] During the testing phase, it is necessary to continuously adjust the point of impact of the spray water onto the wall. Currently, the height of the spray nozzles can only be adjusted manually. Furthermore, if multiple spray nozzles are used simultaneously, the operator needs to frequently adjust the height of each nozzle synchronously during the testing process, which is obviously very inefficient.

[0007] Therefore, in actual work, if the design can autonomously and stably adjust the height of the spray nozzle for spray testing and simultaneously test multiple walls, the testing efficiency will be greatly improved. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide an indoor wall spray testing device.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An indoor wall spray testing device includes a spray mechanism and a lifting mechanism for the lifting spray mechanism.

[0011] The spraying mechanism includes a spray pipe structure, on which a number of arm wheel assemblies that are mounted and connected to the spray pipe structure are connected to the wall.

[0012] The arm wheel assembly includes an adjustable arm with an adjustable length and a contact wheel mounted on the adjustable arm. The contact wheel adjusts the contact angle with the wall through an angle adjustment structure. After the angle is adjusted, the contact rolling force between the contact wheel and the wall is increased.

[0013] Preferably, the nozzle structure includes a pair of horizontally spaced tubes and a pair of longitudinal tubes communicating with the horizontally spaced tubes; the longitudinal tubes are arranged perpendicularly to the horizontally spaced tubes.

[0014] The two ends of the horizontal and vertical tubes are detachably connected by a bend.

[0015] It also includes the water inlet pipe connected to the bend;

[0016] Each of the longitudinal tubes has a wheel assembly installed at its center.

[0017] Preferably, the longitudinal and transverse pipes are equipped with a plurality of spray pipes that are arranged to spray outwards, and the ends of the spray pipes are fitted with nozzles.

[0018] Preferably, the adjusting arm includes an arm cylinder portion fixedly mounted on the longitudinal tube, and a pull arm portion is slidably connected to the arm cylinder portion;

[0019] The arm section has several pin holes for length adjustment; the arm cylinder section is threaded with a pin-fixing screw that passes through the pin holes.

[0020] Preferably, the angle adjustment structure includes a fan-shaped adjustment housing fixedly installed on the pull arm portion;

[0021] The touch wheel is rotatably connected to a touch wheel frame, and the touch wheel frame is fixedly mounted with an adjusting fan plate, which is rotatably connected to a fan-shaped adjusting housing;

[0022] An adjustment port is provided at the outer end of the fan-shaped adjustment housing;

[0023] The adjustment mechanism locks the fan-shaped housing and the adjustment fan plate together via a locking structure.

[0024] Preferably, the locking structure includes a plurality of locking threaded holes formed on the adjusting fan plate; the locking threaded holes are distributed in an arc shape;

[0025] It also includes a locking bolt that is threaded onto the sector-shaped adjusting housing, and the locking bolt is fastened to the locking thread hole.

[0026] Preferably, a connecting beam is fixedly connected between the centers of the longitudinal tubes;

[0027] The lifting mechanism includes a pull rope, one end of which is fixed to the center of the connecting beam.

[0028] Preferably, the lifting mechanism further includes a plurality of guide pulleys, through which the pull rope is guided;

[0029] The other end of the pull rope is wound around a reel, which is equipped with a motor.

[0030] Preferably, a plurality of guide rails are slidably connected to the connecting beam, and adjustable support seats are respectively installed at the top and bottom of the guide rails;

[0031] Adjustable support bases are placed on the ground and ceiling.

[0032] This utility model has the following beneficial effects:

[0033] 1. The spraying mechanism enables simultaneous spraying tests on four sides of building walls, such as bathroom walls. During the test, the spraying position is adjusted by the lifting mechanism to achieve all-round coverage of the wall structure. This not only significantly improves the testing effect and efficiency, but also greatly reduces the workload of manual testing.

[0034] 2. During operation, after the adjusting arm is initially adjusted to the desired length, the contact wheel is flipped. At this point, the adjusting plate rotates relative to the adjusting port, causing the contact wheel to tilt upwards and press against the wall. Under the combined force of the entire device's gravity and the contact wheel's pressure, a high contact force is achieved between the contact wheel and the wall, ensuring the contact wheel remains rolling on the wall during lifting. The locking bolt is then threaded into the locking thread hole to maintain its position.

[0035] The entire device solves the technical defect of unstable lifting caused by the recoil force generated after the spray water hits the wall during the spraying process (without the touch wheel installed, the entire spray pipe structure shakes violently during the test, making it impossible to complete the test).

[0036] 3. The lifting mechanism enables unmanned testing, which greatly improves testing efficiency while reducing manpower consumption. Attached Figure Description

[0048] Example 1

[0049] like Figure 1-6As shown, an indoor wall spray testing device includes a spray mechanism 1 and a lifting mechanism for the lifting spray mechanism 1. The spray mechanism 1 enables simultaneous four-sided spray testing of building walls, such as bathroom walls. During the test, the lifting mechanism adjusts the spray position to achieve comprehensive coverage of the wall structure, significantly improving testing effectiveness and efficiency while greatly reducing the workload of manual testing.

[0050] Specifically, the spraying mechanism 1 includes a spray pipe structure, which has the following structure: the spray pipe structure includes a pair of horizontal pipes 11 spaced apart front to back and a pair of vertical pipes 12 spaced apart left to right and connected to the horizontal pipes 11; the vertical pipes 12 are arranged perpendicularly to the horizontal pipes 11. The two ends of the horizontal pipes 11 and the vertical pipes 12 are detachably connected by a bend 13.

[0051] Specifically, similar to existing methods, the two ends of the bend 13 have flange rings, and correspondingly, the two ends of the horizontal pipe 11 and the vertical pipe 12 have flange rings. The connection between the flange rings enables detachment, which is intended to facilitate carrying.

[0052] After installation, the above-mentioned nozzle structure forms a rectangular spray pipe, enabling simultaneous spraying of four walls.

[0053] According to the existing spray water inlet method, an inlet pipe 14 is connected to one of the bends 13. According to the existing spray water supply method, the inlet pipe 14 is connected to an external water supply pipe (using a flexible hose connection for easy lifting and lowering). The external water supply pipe introduces test water at a certain pressure into the inlet pipe and then into the entire spray pipe structure. According to the existing method, a valve (not shown in the figure) is installed on the inlet pipe.

[0054] According to the existing spraying method, several spray pipes 18 with outward spraying configuration are installed on the longitudinal pipe 12 and the horizontal pipe 11. Spray nozzles are installed at the ends of the spray pipes 18. During operation, the spray nozzles spray test water at a certain pressure onto the wall.

[0055] Example 2

[0056] like Figure 1-6 As shown, this embodiment, based on the structure of embodiment 1, allows the entire device to rise and fall against the wall during the test. This serves two purposes: firstly, to increase stability during the rising and falling process (during the spraying process, the water spray generates opposing impact forces; using a wall-mounted rising and falling method greatly improves the stability of both the spraying and the rising and falling); and secondly, the rising and falling mechanism enables multi-directional coverage of the wall during the spraying test.

[0057] Specifically, in order to achieve smooth lifting and lowering, the above-mentioned nozzle structure is equipped with several arm wheel assemblies that are connected to the wall.

[0058] Specifically, a boom wheel assembly 19 is installed at the center of each longitudinal tube 12. The specific structure of the boom wheel assembly 19 is as follows:

[0059] The arm wheel assembly 19 includes an adjustable arm 191 with an adjustable length and a touch wheel 193 mounted on the adjustable arm 191. The touch wheel 193 adjusts the contact angle with the wall through an angle adjustment structure. After the angle is adjusted, the contact rolling force between the touch wheel 193 and the wall is increased.

[0060] Specifically, similar to the existing telescopic rod structure with adjustable length, the aforementioned adjusting arm 191 includes an arm cylinder portion fixedly installed on the longitudinal tube 12 (the arm cylinder portion is fixedly connected to the longitudinal tube 12), and a pull arm portion (the arm cylinder portion has a cylinder cavity of a certain depth) slidably connected to the arm cylinder portion; the pull arm portion is provided with several pin holes for length adjustment; and a pin fixing screw that passes through the pin holes is threadedly connected to the arm cylinder portion.

[0061] The above structure allows for length adjustment of the adjusting arm 191 based on the wall position, adjusting it until the contact wheel 193 can contact the wall, preparing for subsequent lifting and rolling. The adjustment method is as follows: after loosening the locking screw, slide the adjusting arm to adjust its length, and then thread the locking screw into the corresponding through pin hole to lock it in place.

[0062] In actual operation, the cylinder seat can be designed as a threaded tube, threadedly connected to the longitudinal tube 12 (the longitudinal tube 12 has a corresponding threaded structure) to facilitate adjustment of the angle of the adjusting arm 191. To increase the stability of the adjusting arm 191 after adjustment, a compression screw (not shown in the figure) can be threaded onto the cylinder seat 121 using a conventional locking method disclosed in existing technology. After adjusting the angle by rotating the thread of the cylinder seat 121, the compression screw presses against the longitudinal tube 12 for auxiliary positioning. In actual operation, after testing, the compression screw (not shown in the figure, using a compression screw for locking and positioning is a conventional application of compression positioning in existing technology) effectively ensures the stability of the adjusting arm 191's posture by pressing against the threaded connection of the cylinder seat 121, that is, the adjusting arm 191 will not unlock and flip during lifting and lowering.

[0063] Example 3

[0064] like Figure 1-6 As shown, in order to adjust the angle of the touch wheel 193, this embodiment is based on the structure of embodiment 2. The above-mentioned angle adjustment structure includes a fan-shaped adjustment housing 192 fixedly installed on the pull arm; the outer end of the fan-shaped adjustment housing 192 is provided with an adjustment port.

[0065] Meanwhile, the touch wheel 193 is rotatably connected to the touch wheel 193 frame, and the touch wheel 193 frame is fixedly installed with the adjustment fan plate 194. The adjustment fan plate 194 is rotatably connected to the fan-shaped adjustment housing 192 (specifically, in the existing manner, the adjustment fan plate 194 is rotatably connected to the fan-shaped adjustment housing 192 through a rotating shaft).

[0066] The sector-shaped adjusting housing 192 and the adjusting sector plate 194 are locked together by a locking structure. The locking structure includes a number of locking threaded holes 1941 opened on the adjusting sector plate 194; the locking threaded holes 1941 are distributed in an arc shape; it also includes locking bolts 195 threadedly connected to the sector-shaped adjusting housing 192, and the locking bolts 195 are fastened to the locking threaded holes 191.

[0067] After initially adjusting the length using the adjusting arm 191, flip the contact wheel 193. At this time, the adjusting fan plate 194 rotates relative to the adjusting port, flipping the contact wheel 193 so that it is tilted upwards and contacts the wall. Under the combined force of the entire device's gravity and the contact pressure of the contact wheel 193, a high contact force is achieved between the contact wheel 193 and the wall, keeping the contact wheel 193 rolling and sliding on the wall during the lifting and lowering process. Then, the locking bolt 195 is threaded into the locking threaded hole 191 to fix the position.

[0068] The entire device solves the technical defect of unstable lifting and lowering caused by the recoil force generated after the spray water hits the wall during the spraying process (without the installation of the touch wheel 193, the entire spray pipe structure shakes violently during the test, making it impossible to complete the test).

[0069] Meanwhile, a connecting beam 15 is fixedly connected between the centers of the aforementioned longitudinal tubes 12; a pair of spaced guide rails 17 are slidably connected to the connecting beams 15, and an adjustment support seat 171 is installed at the top and bottom of the guide rails 17 respectively; the adjustment support seat 171 is supported on the ground and the ceiling.

[0070] Specifically, during the installation of the entire device, the guide rail rod 17 is passed through the through hole on the connecting beam 15, and then the top position adjustment support 171 and the bottom position adjustment support 171 are supported on the ceiling and floor of the bathroom.

[0071] Therefore, in order to increase the stability of the guide rail rod 17 during actual operation, the above-mentioned adjustment support is designed to be made of rubber, and a fixed screw is fixed on the adjustment support 171. The screw is threadedly connected to the threaded long grooves opened at the top and bottom of the guide rail rod 17 to achieve adjustment support.

[0072] The above-mentioned adjustable support 171 and screw threaded connection guide rail rod 17 are conventional methods for fixing the guide rail rod 17 after vertical installation of the existing technology.

[0073] The above structure further ensures that the nozzle structure can rise and fall smoothly during the lifting and lowering process.

[0074] Example 4

[0075] like Figure 1-6As shown, this embodiment is based on the structure of embodiment 3. In order to realize automatic lifting spray test (spray test often takes a long time, so it requires a dedicated person to monitor the test) and realize unmanned monitoring test, the above-mentioned lifting mechanism includes a pull rope 3. One end of the pull rope 3 is fixed to the center of the connecting beam 15 (in the existing way, a hanging ring 151 is welded to the center of the connecting beam 15 to hang and fix the pull rope 3).

[0076] Meanwhile, in order to guide the pull rope 3 and avoid interference with it, in accordance with the conventional method of guiding the pull rope 3 disclosed in the prior art, the above-mentioned lifting mechanism also includes several guide pulleys 2, and the pull rope 3 is guided by the guide pulleys 2.

[0077] Specifically, similar to existing methods, the guide pulley 2 is fixed to the ceiling, and the pull rope 3 passes through the groove of the guide pulley 2. Under the guiding action, the pull rope 3 can be pulled smoothly.

[0078] Meanwhile, the other end of the aforementioned pull rope 3 is wound around a reel 41, on which a motor 4 is mounted. In the existing method, the motor 4 is raised and fixed to the ground (if using the conventional motor mounting method disclosed in the prior art, the motor 4 is fixed by a motor bracket to ensure stable operation; the motor bracket is not shown in the figure). The motor 4 is a reversible motor disclosed in the prior art, so that when the motor drives the reel to wind up the pull rope 3, the entire device is raised to spray water onto a higher part of the wall, and vice versa.

[0079] During the test, maintain a safe distance between the motor and the test area.

[0080] This method enables automated spray testing.

[0081] The use of a motor and a roller drive for lifting is a conventional method disclosed in the prior art. Similarly, the use of a guide pulley 2 and a guide rope 3 is also a conventional method used in the prior art to improve the stability of lifting. Those skilled in the art can understand the specific working principle and working structure of how the motor, roller, rope 3, and guide pulley 2 work together to lift the nozzle by consulting technical manuals and dictionaries.

[0082] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
