Description

Technical Field

[0001] The utility model belongs to the technical field of fire protection, and particularly relates to a fire hydrant pipe network pressure loss testing device. Background Art

[0002] Fire hydrants, formally known as fire hydrants or fire hydrants, are fixed fire-fighting facilities whose main function is to provide water for firefighting and rescue operations. They are usually installed in easily accessible locations such as inside buildings, public places, on both sides of streets, and in outdoor open areas. The existing fire hydrant network pressure loss test device connects the test device to the fire hydrant network, and then detects the pressure loss value through the operation of ultrasonic flow sensors and pressure sensors. However, in actual use, since the pressure sensor is bolted to the test device, it is not convenient for subsequent maintenance.

[0003] For example, the utility model with announcement number CN 219870244 U discloses a fire hydrant flow pressure test device, including: a pipeline, a shell, an upper cover, an ultrasonic flow sensor, a touch screen, a pressure sensor, a DC power supply and a plurality of data connection lines; the shell is a hollow structure, a pipeline is horizontally penetrated through the lower part of the shell, the two ends of the pipeline are arranged outside the shell, the middle part of the pipeline is arranged inside the shell, and an ultrasonic flow sensor and a pressure sensor are respectively arranged on the middle part of the pipeline; a touch screen and a DC power supply are also arranged inside the shell; an upper cover is arranged on the upper part of the shell; the touch screen is connected to the ultrasonic flow sensor, the pressure sensor and the DC power supply respectively through data connection lines. In the technical solution of this patent, the fire hydrant flow pressure loss is detected by the cooperation of the ultrasonic flow sensor and the pressure sensor, but in the actual use process, in order to ensure the normal use of the sensor, the sensor needs to be frequently inspected and maintained. In the process of disassembling and assembling the pressure sensor, personnel need to spend a long time to remove the bolts connected to the flange, which is time-consuming and laborious.

A pressure sensor 110 is plugged into the avoidance opening opened on the upper surface of the mounting seat 109. A height adjustment module for adjusting the height of the connecting pipe 106 is also provided on the base 101, and a quick fixing module for fixing the pressure sensor 110 is also provided on the mounting seat 109.

[0022] like Figure 1 , 2 As shown in FIG. 4 , the height adjustment module includes electric push rods 104 arranged on the left and right sides of the base 101 , and the telescopic ends of the electric push rods 104 are fixed to the lower surface of the equipment box 103 by bolts.

[0023] like Figure 2 , 3 As shown in , 4, the quick fixing module includes a mounting ring 201 welded and fixed on the upper surface of the mounting seat 109, four evenly distributed sliding posts 202 are slidably arranged on the outer arc surface of the mounting ring 201, and a fixing sleeve 203 is respectively arranged between two adjacent sliding posts 202 in front and behind, and the two fixing sleeves 203 are in contact with the outer side of the flange of the pressure sensor 110, and a driving unit for driving the fixing sleeve 203 to move is also arranged on the mounting ring 201, and a buffer unit for buffering the fixing sleeve 203 is also arranged on the sliding post 202; the buffer unit includes a buffer spring 204 arranged between the sliding post 202 and the fixing sleeve 203, and the buffer springs 204 are all sleeved on the outer arc surface of the sliding post 202; the driving unit includes a screw rod 205 rotatably arranged on the side of the two fixing sleeves 203 away from the vertical center of the mounting seat 109, the screw rods 205 are all threadedly connected to the mounting ring 201, and a handwheel 206 is arranged on the side of the screw rod 205 away from the vertical center of the handwheel 206.

[0024] like Figure 1 , 2 As shown in FIG. 4 , a control box 301 is disposed on the upper surface of the equipment box 103 , a control panel 302 is disposed on the front side of the control box 301 , the electric push rod 104 , the ultrasonic flow sensor 108 and the pressure sensor 110 are all electrically connected to the control box 301 , and the control box 301 is electrically connected to the control panel 302 .

[0025] When it is necessary to conduct a pressure loss test on the fire hydrant network, the control panel 302 controls the operation of the electric push rods 104 through the control box 301, so that the telescopic ends of the two electric push rods 104 extend or retract, thereby causing sliding between the base 101 and the support frame 102, so that the equipment box 103 drives the connecting pipe 106 to rise or fall, so that the connecting pipe 106 can adapt to the height of the connection position for connection.
