[0002] Fire-fighting equipment is widely used in existing shopping malls, houses, warehouses and other areas, and fire hydrants are installed near various fire-fighting facilities for water collection in emergency situations. For fire hydrants inside some buildings, due to their unfixed positions, the laying of pipelines needs to be adjusted according to the buildings, etc., which leads to the fire hydrants in different locations, especially the quality of indoor fire hydrants is not uniform, which is prone to potential safety hazards. In order to test the actual status of indoor fire hydrants, it is necessary to carry out a pressure test after installation or after a period of use. The existing testing methods are mostly to seal the main pipeline or a branch, and then inject pressure at an entrance and exit, and measure separately at fire hydrants in different positions, so as to obtain the transmission and maintenance of pressure, and obtain whether the pressure resistance value meets the requirements. However, the existing measuring devices have relatively single functions, and various devices realize different functions respectively, and cannot perform pressure injection and measurement at the same time.

DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings.

[0020] In order to more clearly understand the technical solutions presented in the embodiments of the present application, the working principle of the existing pressure resistance test of indoor fire hydrants is first introduced.

[0021] During the existing pressure resistance test of indoor fire hydrants, pressure gauges, air pumps, connectors, support frames and other structures are used. Personnel are required to seal the pipeline on site, and then pump air into the inside after connection, and perform pressure tests at other fire hydrants in the redirected pipeline to achieve a sealing effect inside the pipeline and draw conclusions on whether the pipeline is leaking. However, a large number of instruments and equipment need to be carried during the existing testing process, and personnel need to move back and forth between different floors and buildings indoors during the testing process. There are many types of equipment, and they are often missed or forgotten, which causes extra labor for personnel. In addition, when the existing air pump pressurizes the pipeline, the pressure is slow due to the limited flow of the air pump. Therefore, the existing equipment needs to be improved to solve these problems.

[0022] See also Figure 1 and Figure 2 , which is a pressure test structure of an indoor fire hydrant disclosed in an embodiment of the present application, comprising: a connecting seat 1, a supporting leg 2, a roller 3, a supporting plate 4, a pressure tank 5, a high-pressure air pump 6, a pressure hose 7, a solenoid valve 8, a connecting frame 9, a sliding seat 10, an adjustment screw 11, an electric telescopic rod 12, a mounting seat 13, a connecting head 14 and a pressure gauge 15. The connecting seat 1 has an inverted U-shape in appearance, and the lower ends of both sides of the connecting seat 1 are fixedly connected with the supporting legs 2 respectively, the rollers 3 are rotatably connected to the lower ends of the supporting legs 2 respectively, the supporting plate 4 is fixedly connected to the inner wall of the connecting seat 1 near the lower end, the pressure tank 5 is fixedly connected to the upper surface of the supporting plate 4, the high-pressure air pump 6 is fixedly connected to the surface of one side of the supporting plate 4, and the output end of the high-pressure air pump 6 is connected to the pressure hose 7 is through-connected with the input end of the pressure tank 5, the connecting frame 9 has an inverted U-shape in appearance, the connecting frame 9 is fixedly connected to the upper surface of the middle position of the connecting seat 1, the sliding seat 10 is slidably connected to the inner wall of the connecting frame 9, the adjusting screw 11 is vertically threadedly connected to the middle part of the connecting frame 9, the lower end of the adjusting screw 11 is rotatably connected to the upper surface of the middle position of the sliding seat 10, the connecting end of the electric telescopic rod 12 is connected to the sliding seat 10, the telescopic end of the electric telescopic rod 12 is fixedly connected with the mounting seat 13, the connector 14 is cooperatively connected in the mounting seat 13, the pressure gauge 15 is connected to one side of the mounting seat 13, the output end of the pressure tank 5 is through-connected with the mounting seat 13 through the pressure hose 7, and the pressure hose 7 at the output end of the pressure tank 5 is connected with the solenoid valve 8.

[0023] Specifically, the connection seat 1 can provide an installation and support position for the equipment, and then cooperate with the support plate 4 at the lower end to form an installation cavity that meets actual needs, which is convenient for connecting components such as the pressure tank 5 and the high-pressure air pump 6, and can form a relatively safe protection area to avoid dangers in situations such as gas pressure leakage, thereby improving safety. The support legs 2 can stably lift the equipment to a certain height, which is convenient for people to connect and operate. The rollers 3 can be flexibly adjusted in the front and rear directions to improve convenience. The pressure tank 5 can store a certain amount of pressurized gas under the operation of the high-pressure air pump 6, which is convenient for quickly filling the fire hydrant pipeline when in use. The pressure hose 7 can transfer the high-pressure gas to the installation seat 13, and then enter the fire hydrant connection port through the connector 14, so that the pressure is transferred to the outside. When in use, the pressure can be adjusted by drilling. The lead screw 11 can make the sliding seat 10 slide up and down along the connecting frame 9, thereby driving the mounting seat 13 at the end to achieve height adjustment, meeting the flexibility in the alignment process and reducing the labor intensity of personnel carrying the mounting seat 13 and the connecting head 14. The solenoid valve 8 set during use can be opened and closed according to the situation. When it is necessary to pressurize the fire hydrant pipe during use, it is opened to allow air pressure to enter the fire hydrant. The set pressure gauge 15 can display the pressure value at the mounting seat 13. After pressurizing at one place, it can be moved to another place for direct measurement. The method of use is expanded, which has good practical value and greatly saves the tediousness of the traditional measurement process. In addition, the structure is an integrated structure, and it is not easy to miss a component, which helps to reduce the labor intensity of personnel. It can also be modified according to actual needs to enhance or expand other functions. It has a wide range of adaptability and good application prospects.
