[0029] See again Figure 1 The prefabricated building water supply pressure testing device provided in this embodiment includes an electric pressure pump 100, a gate valve assembly 200, a water supply pipeline assembly 300, a water pressure gauge assembly 400, an air vent valve 500, a water storage tank, a housing, and casters 600. The electric pressure pump 100, the gate valve assembly 200, the water pressure gauge assembly 400, and the air vent valve 500 are all connected to the water supply pipeline assembly 300. The water supply pipeline assembly 300 is connected to the housing. The water storage tank is located inside the housing. The casters 600 are fixed to the bottom of the housing.

[0030] In this embodiment, the electric pressure pump 100 is fixed to the outer surface of the top of the housing. The electric pressure pump 100, gate valve assembly 200, water pressure gauge assembly 400, and air vent valve 500 are all connected to the water supply pipeline assembly 300. A water storage tank containing a certain amount of water is placed inside the housing. The water supply pipeline assembly 300 is connected to the water storage tank. Under the combined action of the electric pressure pump 100, gate valve assembly 200, and air vent valve 500, the water in the storage tank is pressurized and transported to the outside of the housing through the water supply pipeline assembly 300. During the process of transporting the water in the storage tank to the outside of the housing, the pressure stops when the water pressure reaches a certain threshold. The detection is achieved by observing the change in the value of the water pressure gauge 410 in the water pressure gauge assembly 400. The bottom of the enclosure is fixedly connected with several casters 600 with brakes. The casters 600 can be used to easily move the prefabricated building water supply pressure test device to the designated location, saving the cost and time of manual handling and improving the flexibility and convenience of the test.

[0031] Specifically, the principle of using the prefabricated building water supply pressure testing device provided in this embodiment to conduct quality inspection of prefabricated buildings is as follows: First, preparation stage: The prefabricated building water supply pressure testing device is moved to the prefabricated building area to be tested using the casters 600, ensuring that the water supply pipe 310 in the water supply pipe assembly 300 can be connected to the flexible water pipe of the prefabricated building to be tested through the flexible hose interface 340. Check whether each component, such as the electric pressure pump 100, gate valve assembly 200, water pressure gauge assembly 400, air vent valve 500, and water storage tank, is intact, whether the connections are tight and secure, and whether there are any leaks. The water pressure gauge 410 is calibrated to ensure that its measurement accuracy meets the requirements so as to accurately read the pressure value during the pressure test. Second, water filling stage: An appropriate amount of water is injected into the water storage tank through an external water source or other suitable water filling method, ensuring that the water level reaches the water volume required for the pressure test, and one end of the water supply pipe 310 in the water supply pipe assembly 300 is placed in the water storage tank.

[0032] Third, the pressure testing and venting stage: At the start of pressure testing, the electric pressure pump 100 is activated, and the vent valve 500 and the second gate valve 220 in the gate valve assembly 200 are opened. Water from the storage tank flows from the water supply pipe 310 (where the second gate valve 220 is located) to the flexible water pipe of the prefabricated building under test, driven by the electric pressure pump 100. At this time, the air in the flexible water pipe of the prefabricated building under test is released through the opened vent valve 500, ensuring that the water pressure in the water supply pipe 310 of the prefabricated building water supply pressure testing device reaches the threshold (e.g., 10 Bar) without air contamination. During the venting process, it can be observed whether there is a continuous flow of water from the outlet of the vent valve 500, and whether the water flow no longer contains air bubbles, to determine whether the air has been completely released. If the water flow from the outlet of the vent valve 500 no longer contains air bubbles, the vent valve 500 can be closed. When the water pressure in the water supply pipe 310 stabilizes at a threshold (e.g., 10 Bar), close the second gate valve 220 and the electric pressure pump 100 to maintain a stable pressure in the closed water supply pipe 310 and begin the pressure holding test.

[0033] Fourth, the pressure holding test phase: Observe the changes in the reading of the water pressure gauge 410 in the water pressure gauge assembly 400 at certain pressure holding intervals. The pressure holding time is determined according to the test standards and building requirements (e.g., an interval of one hour). After the water pressure in the water supply pipe 310 reaches the threshold, if the reading of the water pressure gauge 410 does not change within the certain pressure holding time interval, it indicates that the prefabricated building under test is qualified; if the reading of the water pressure gauge 410 decreases within the certain pressure holding time interval, it indicates that the prefabricated building under test is unqualified. For example, after the water pressure reaches 10 Bar, stop pressurizing and maintain it for 1 hour. If the value displayed by the water pressure gauge 410 remains unchanged at 10 Bar, it indicates that the test object (the prefabricated building under test) is qualified; if the value displayed by the water pressure gauge 410 is lower than 10 Bar, it indicates that the test object (the prefabricated building under test) is unqualified.

[0034] Fifth, drainage stage: After the water pressure test is completed, open the first gate valve 210 and the third gate valve 230 in the gate valve assembly 200. The water in the water supply pipeline 310 can flow out from the outlet of the drain pipe 330 in the water supply pipeline assembly 300 and from the outlet of the water supply pipeline 310 where the first gate valve 210 is located.

[0035] In one embodiment, such as Figure 1 As shown, the water supply pipeline assembly 300 includes a water supply pipeline 310, several sub-water supply pipes, several equal-diameter tees 320, a drain pipe 330, a hose connector 340, and an elbow adapter 350; the several sub-water supply pipes are fixedly connected through the several equal-diameter tees 320 to form the water supply pipeline 310; the drain pipe 330 is connected to the water supply pipeline 310 through the elbow adapter 350; the hose connector 340 is sleeved on the water supply pipeline 310; the water supply pipeline 310 passes through the top of the tank and extends into the interior of the water storage tank.

[0036] In this embodiment, several sub-water supply pipes are fixedly connected by several equal-diameter tees 320 to form a water supply pipe 310. The layout and direction of the water supply pipe 310 can be adjusted according to actual needs, improving the flexibility of the water supply pipe 310. Simultaneously, when the water supply pipe 310 is damaged or requires repair, the sub-water supply pipe with the problem can be located more accurately, facilitating partial replacement or repair without requiring large-scale disassembly and replacement of the entire water supply pipe 310, thus significantly reducing maintenance costs and time. One end of the water supply pipe 310 is connected to the flexible water pipe of the prefabricated building to be tested via a flexible connector, enabling the water in the storage tank to be transported to the flexible water pipe of the prefabricated building through the water supply pipe 310. The elbow adapter 350 can be an adapter with an outer diameter of 25 mm and a 90° bend, so as to serve a connection function while preventing water backflow. The flexible hose interface 340 is fitted onto the water supply pipe 310, which facilitates the flexible connection between the water supply pipe 310 and the external prefabricated building or other piping systems to be tested, without the need for complex modifications or replacement of pipe fittings to the water supply pipe 310, thus enhancing the compatibility of the water supply pressure testing device for prefabricated buildings.

[0037] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, it also includes a support assembly 800 and an acceptance plate assembly 900; the acceptance plate assembly 900 is fixedly connected to the support assembly 800; the support assembly 800 is fixedly connected to the box body and the water supply pipe assembly 300.

[0038] Specifically, the support assembly 800 includes a first U-shaped steel channel 810, a second U-shaped steel channel 820, a first U-shaped channel connector 830, and a first bolt 840; the first U-shaped steel channel 810 is vertically fixed to the top of the second U-shaped steel channel 820 through the first U-shaped channel connector 830 and the first bolt 840; the bottom of the second U-shaped steel channel 820 is vertically fixed to the top of the box body.

[0039] In this embodiment, the first U-shaped connector 830 can be a connecting piece, the specifications of which can be selected according to actual needs. The outer diameters of the first U-shaped steel channel 810 and the second U-shaped steel channel 820 are the same (for example, both are 25 mm). The bottom of the second U-shaped steel channel 820 is vertically fixed to the outer surface of the top of the box, and its top is vertically fixed to the first U-shaped steel channel 810 by the first U-shaped connector 830 and several first bolts 840, so that the first U-shaped steel channel 810 and the second U-shaped steel channel 820 form a "T"-shaped support after being fixedly connected. The water supply pipe assembly 300 is fixedly connected to the first U-shaped steel channel 810 and the second U-shaped steel channel 820, which can effectively utilize space, avoid messy intersections between pipes, make the layout of the water supply pipe assembly 300 more regular, and facilitate management and maintenance. In addition, the acceptance plate assembly 900 is fixedly connected to the second U-shaped steel channel 820 in the bracket assembly 800, providing a suitable display position for the acceptance plate body 910 in the acceptance plate assembly 900, which is conducive to quality inspectors viewing the information recorded on the acceptance plate body 910.

[0040] In one embodiment, such as Figure 1 As shown, the support assembly 800 also includes a plurality of water pipe plastic clamps 850; the plurality of water pipe plastic clamps 850 are fixed at intervals on the end faces of the first U-shaped steel channel 810 and the second U-shaped steel channel 820 on the same side; the water delivery pipe assembly 300 is fixedly connected to the plurality of water pipe plastic clamps 850.

[0041] In this embodiment, the water supply pipe 310 in the water supply pipe assembly 300 is clamped onto several plastic pipe clamps 850. The outer diameter of the water supply pipe 310 is the same as that of the plastic pipe clamps 850, enabling the water supply pipe 310 to be clamped onto the plastic pipe clamps 850. The outer diameter of the plastic pipe clamps 850 is the same as that of the first U-shaped steel channel 810 and the second U-shaped steel channel 820. The plastic pipe clamps 850 with the same outer diameter can work together better with the first U-shaped steel channel 810 and the second U-shaped steel channel 820 during connection and under stress. When the water supply pipe 310 is subjected to forces such as internal water pressure, external impact, or its own weight, the plastic pipe clamps can transmit these forces more evenly to the first U-shaped steel channel 810 and the second U-shaped steel channel 820. The same outer diameter makes the contact area and transmission path more regular, thereby enhancing the structural strength of the entire support assembly 800 and the water supply pipe 310 and improving the stability of water delivery by the water supply pipe 310.

[0042] In one embodiment, such as Figure 2 , Figure 3 as well as Figure 4As shown, the acceptance plate assembly 900 includes an acceptance plate body 910, a plurality of third U-shaped steel channels 920, a second U-shaped channel connector 930, and a second bolt 940; the plurality of third U-shaped steel channels 920 are fixed to the second U-shaped steel channel 820 at intervals and vertically through the second U-shaped channel connector 930 and the second bolt 940; the plurality of third U-shaped steel channels 920 are located between the first U-shaped steel channel 810 and the box body; the acceptance plate body 910 is fixedly connected to the plurality of third U-shaped steel channels 920.

[0043] In this embodiment, the plurality of third U-shaped steel channels 920 includes at least two third U-shaped steel channels 920. The outer diameter of the third U-shaped steel channel 920 is the same as that of the second U-shaped steel channel 820. Structures with the same outer diameter can work together better when subjected to external forces or transmitting forces. When the acceptance plate assembly 900 is subjected to external forces such as wind loads or accidental collisions, the third U-shaped steel channels 920 can transmit these forces more evenly to the second U-shaped steel channel 820. Because their outer diameters are the same, the force transmission path is more regular, avoiding local structural damage due to force concentration and improving the overall structural stability of the acceptance plate assembly 900.

[0044] The third U-shaped steel channel 920 is fixed to the second U-shaped steel channel 820 by the second U-shaped connector 930 and the second bolt 940. On the one hand, the spacing between several third U-shaped steel channels 920 can be flexibly adjusted according to the size and shape of the acceptance plate body 910 and the actual installation requirements. On the other hand, the second U-shaped connector 930 and the second bolt 940 are used together to connect and fix the third U-shaped steel channel 920, which can withstand greater tensile, compressive and shear forces, so as to limit the relative displacement between the third U-shaped steel channels 920 to a certain extent, and ensure that the third U-shaped steel channels 920 are fixed vertically and evenly spaced on the second U-shaped steel channel 820.

[0045] In one embodiment, such as Figure 1 As shown, the gate valve assembly 200 includes a first gate valve 210, a second gate valve 220, and a third gate valve 230; the first gate valve 210, the second gate valve 220, and the third gate valve 230 are all fixedly connected to the water supply pipe 310, wherein the first gate valve 210 is adjacent to the air vent valve 500, and the second gate valve 220 and the third gate valve 230 are adjacent to the housing.

[0046] In this embodiment, the outer diameters of the first gate valve 210, the second gate valve 220, and the third gate valve 230 are all the same as the outer diameter of the water supply pipe 310. This identical outer diameter ensures a tighter connection between the gate valves and the water supply pipe 310, thereby reducing the risk of water leakage. The first gate valve 210 and the third gate valve 230 are closed during the pressure test, both serving as drain valves for drainage. Having two drain valves (the first gate valve 210 and the third gate valve 230) provides a more flexible drainage method, allowing different drain valves to be opened depending on the application scenario or drainage requirements. The second gate valve 220 is open during the pressure test; once the pressure reaches the threshold, the pressure test ends and the second gate valve 220 closes.

[0047] In one embodiment, such as Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the box body includes a box frame 700, a steel plate, solid wood plywood, and a fixing component; the steel plate is fixedly connected to the outer surface of the box frame 700 through the fixing component; the solid wood plywood is fixedly connected to the outer surface of the steel plate.

[0048] Specifically, the fixing component includes a plurality of third U-groove connectors 710 and a plurality of third bolts 720; the box frame 700 is formed by a plurality of fourth U-shaped steel channels 730 fixedly connected by the plurality of third U-groove connectors 710 and the plurality of third bolts 720.

[0049] In this embodiment, the box frame 700 is composed of several fourth U-shaped steel channels 730 connected end to end, wherein the steel channels are fixedly connected by several third U-shaped connectors 710 and several third bolts 720. A steel plate (not shown in the figure) is fixedly connected to the outer surface of the box frame 700. Due to the high strength and hardness of the steel plate, fixing the steel plate to the outer surface of the box frame 700 provides strong support and protection for the box. In the prefabricated building water supply pressure testing device, the box needs to withstand the weight of the internal equipment (such as a water storage tank) and the external forces that may be applied during movement and use. The high strength of the steel plate can effectively prevent box deformation and ensure the safety of the internal equipment. The specifications of the solid wood plywood (not shown in the figure) are set according to actual needs, and it can play a certain role in sound insulation, reducing the noise generated by the operation of the internal equipment during device operation. In places where noise is limited (such as construction sites near residences or hospitals), this sound insulation performance can reduce the interference of the device's operation on the surrounding environment.

[0050] In one embodiment, such as Figure 1As shown, the water pressure gauge assembly 400 includes a water pressure gauge 410, a first sub-water supply pipe 420, and a second sub-water supply pipe 430; the water pressure gauge 410 is fixedly connected to the first sub-water supply pipe 420; the first sub-water supply pipe 420 is fixedly connected to the second sub-water supply pipe 430 through the elbow adapter 350; the second sub-water supply pipe 430 is fixedly connected to the water supply pipe 310 through the equal diameter tee 320; the second sub-water supply pipe 430 is parallel to the housing.

[0051] In this embodiment, the second sub-water supply pipe 430 is fixedly connected to the water supply pipe 310 via an equal-diameter tee 320. This connection method ensures that the water pressure in the second sub-water supply pipe 430 is consistent with the pressure in the water supply pipe 310. Since the second sub-water supply pipe 430 is parallel to the housing, its position is relatively stable and will not cause abnormal pressure changes due to its own bending or twisting. Then, the first sub-water supply pipe 420 and the water pressure gauge 410 are connected via an elbow adapter pipe 350, which accurately transmits the pressure in the water supply pipe 310 to the water pressure gauge 410, ensuring that the measured pressure value truly reflects the actual pressure of the water supply pipe 310 system and improving the accuracy of pressure measurement.

[0052] Furthermore, the water pressure gauge 410 is connected to the water supply pipe 310 via a first sub-water supply pipe 420 and a second sub-water supply pipe 430, with the second sub-water supply pipe 430 parallel to the housing. This allows the entire connection structure to be rationally laid out without occupying excessive space. In environments where space utilization and overall coordination are critical, a rational spatial layout helps improve construction efficiency and allows the entire prefabricated building water supply pressure testing device to better integrate with surrounding building facilities.

[0053] This utility model embodiment provides a prefabricated building water supply pressure testing device, which includes an electric pressure pump 100, a gate valve assembly 200, a water supply pipeline assembly 300, a water pressure gauge assembly 400, an air release valve 500, a water storage tank, a housing, and casters 600. The electric pressure pump 100, the gate valve assembly 200, the water pressure gauge assembly 400, and the air release valve 500 are all connected to the water supply pipeline assembly 300. The water supply pipeline assembly 300 is connected to the housing. The water storage tank is located inside the housing. The casters 600 are fixed to the bottom of the housing. In this utility model embodiment, under the combined action of the electric pressure pump 100, the gate valve assembly 200, and the air release valve 500, water in the water storage tank can be transported to the outside of the housing through the water supply pipeline assembly 300.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model.
