Description

Technical Field

[0001] This utility model belongs to the technical field of building construction testing devices, specifically relating to a mobile water spray test water supply device with adjustable water pressure. Background Technology

[0002] In the field of construction engineering, after the decoration and renovation work is completed, it is generally necessary to conduct a water spray test on the exterior windows and walls. At present, the most common method for water spray testing is to use a water spray pipe with multiple spray nozzles to evenly spray different areas of the windows and walls. This method has good testing results.

[0003] Because the water spray system needs to be moved frequently during testing, the water supply system also needs to be moved multiple times. Where it's near a tap, a direct connection to the water supply is sufficient. However, in more common situations, due to a lack of water sources or their distance from the testing site, water is often supplied via buckets, and a pump draws water from the buckets to provide the spray system with pressure. For cost reasons, the pumps used in water spray tests often lack precise pressure regulation, resulting in varying water pressures at different floors or heights, leading to significant errors in the test results. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the present invention aims to provide a water spraying device for water spraying test that does not require disassembly, so that the water spraying device can be quickly deployed during the test and is less likely to produce saliva.

[0005] To address the aforementioned technical problems, this utility model discloses a mobile water supply device for water spraying tests with adjustable water pressure, comprising a water tank and a water pump located outside the water tank. A connecting pipe extends from the lower part of the water tank and connects to the water pump. The water pump supplies water to the spray pipe through a water delivery pipe. A bypass return pipe is provided on the upper part of the water delivery pipe near the water pump. The return pipe is used to return some of the water delivered by the water pump back to the water tank to reduce the water pressure supplied from the water delivery pipe to the spray pipe. A return valve is provided on the return pipe. By adjusting the return valve, the return water flow rate of the return pipe is adjusted, thereby achieving the adjustment of the spraying pressure of the spray pipe during the water spraying test.

[0006] Preferably, the return water pipe is arranged vertically.

[0007] Preferably, the upper end of the return water pipe extends into the water bucket.

[0008] Preferably, the top of the return water pipe is arranged in an inverted U-shape.

[0009] Preferably, the return water valve is located in the middle or upper part of the return water pipe.

[0010] Preferably, it also includes a mobile platform for placing the bucket.

[0011] Preferably, the mobile platform includes a flatbed trolley.

[0012] This utility model relates to a mobile water supply device for spray testing with adjustable water pressure. It eliminates the need to replace the water pump with a high-grade one. By installing a return water pipe with a return water valve on the basis of existing equipment, manual adjustment of the spray pressure can be achieved at a low cost, which has great application prospects. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of a mobile water supply device for water spraying tests with adjustable water pressure.

[0014] The following are the labels in the diagram: 1. Water bucket; 2. Water pump; 3. Water delivery pipe; 4. Connecting pipe; 5. Return water pipe; 6. Return water valve; 7. Mobile platform. Detailed Implementation

[0015] The present invention will be further described in detail below through embodiments, so that those skilled in the art can implement it based on the description.

[0016] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0017] like Figure 1 As shown, a mobile water supply device for water spraying tests with adjustable water pressure includes a water tank 1 and a water pump 2 located outside the water tank. A connecting pipe 4 extends from the lower part of the water tank 1 and is connected to the water pump. The water pump supplies water to the spray pipe through a water delivery pipe 3. A bypass return pipe 5 is provided on the upper part of the side of the water delivery pipe 3 near the water pump. The return pipe 5 is used to return some of the water delivered by the water pump back to the water tank to reduce the water pressure supplied from the water delivery pipe to the spray pipe. A return valve 6 is provided on the return pipe 5. By adjusting the return valve, the return water flow rate of the return pipe is adjusted, thereby realizing the adjustment of the spraying pressure of the spray pipe during the water spraying test.

[0018] The return water pipe 5 is vertically arranged, and the top of the return water pipe 5 is inverted U-shaped. The upper end of the return water pipe extends into the water bucket 1.

[0019] The return water valve 6 is located in the middle or upper part of the return water pipe, which makes it convenient for staff to adjust the return water valve 6.

[0020] It also includes a mobile platform 7 for placing the water bucket, which is a flatbed trolley. The flatbed trolley is convenient, practical and low in cost.

[0021] Working principle: The water pressure at the outlet of water pump 2 is basically constant. Adjusting the return water valve 6 will increase the flow rate in the return water pipe 5, thus reducing the water pressure in the delivery water pipe 3. Conversely, when the flow rate in the return water pipe 5 decreases or is closed, the water pressure in the delivery water pipe 3 will increase.

[0022] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and embodiments shown and described herein.
