After adopting the above solution, during use, the connecting pipe 5 is fixedly connected to the water outlet of the fire hydrant. When detecting the static water pressure of the fire hydrant, only the first manual ball valve 3 is opened, and then the fire hydrant is opened. Water passes through the connecting pipe 5 and the first manual ball valve 3 and enters the detection connecting pipe 1. The static water pressure of the fire hydrant can be directly reflected by the pressure transmitter 2; when it is necessary to detect the dynamic water pressure of the fire hydrant, both the first manual ball valve 3 and the second manual ball valve 4 are opened simultaneously, and the water flow will pass through the detection connecting pipe 1. The dynamic water pressure of the fire hydrant can be directly reflected by the pressure transmitter 2; through the pressure transmitter 2, the first manual ball valve 3, and the second manual ball valve 4 provided by the present utility model, only opening the first manual ball valve 3 can be used to detect the static pressure, and after the detection is completed, the first manual ball valve 3 is closed, and the water in the detection connecting pipe 1 will not be discharged, which is convenient for transferring the water to the collection container; opening both the first manual ball valve 3 and the second manual ball valve 4 simultaneously can be used to detect the dynamic pressure, and the switching is convenient and rapid, and the static pressure and dynamic pressure of the fire hydrant water outlet can be quickly detected.

[0038] Optionally, as Figure 1 and Figure 2 shown, in this embodiment, it further includes a fixing mechanism 6. The connecting pipe 5 is fixedly connected to the water outlet of the fire hydrant by using the fixing mechanism 6, and the fixing mechanism 6 includes: a steel ring 61, a threaded rod 64, and a wing nut 65. The two steel rings 61 are spaced apart, and the two steel rings 61 are respectively sleeved on the connecting pipe 5 and the water outlet of the fire hydrant. A first fixing block 62 and a second fixing block 63 are respectively fixed at both ends of the steel ring 61. The threaded rod 64 is fixed on the first fixing block 62 and penetrates through the second fixing block 63. The wing nut 65 is installed on the extending end of the threaded rod 64 by means of thread screwing. After adopting the above solution, when fixing the connecting pipe 5, first sleeve the steel ring 61 on the water outlet of the fire hydrant, then dock the connecting pipe 5 with the water outlet of the fire hydrant, then move the position of the steel ring 61 so that the two steel rings 61 are respectively sleeved on the connecting pipe 5 and the water outlet of the fire hydrant, and finally tighten the wing nut 65.
