Specific embodiment
Technical solution of the present invention is further illustrated with reference to the accompanying drawings and examples.As shown in Figures 1 to 4, at this
It mainly include exterior bayonet slot (or outer side bayonet slot) 1, inner card cage (or interior side bayonet slot) 3 and sealing ring 5 in embodiment.Inner card cage
With striker 2 is provided on exterior bayonet slot.The edge of exterior bayonet slot has handle portion 4.Water filling port 6 is formed among inner card cage.Exterior bayonet slot
Inward flange has groove 7, has the flange 8 being adapted to groove on the extrados of inner card cage that is, on intrados.At work, it infuses
Water pipe 11 is sealedly connected and fixed in inner card cage, and device is fixed on wall 12, will be collected by sensor 9 and data line 10
Measurement data.
In this embodiment, exterior bayonet slot and inner card cage internal structure cooperate, close to connect, and form measuring device main body；Outside
Card slot, inner card cage are divided into two symmetric parts, are closely connected by bolt；Handle is located on exterior bayonet slot；Striker equably divides
Cloth is in exterior bayonet slot, inner card cage surface；Sealing ring is located at inner card cage inner radius, is fitted close with water filling port.
As shown in Figures 2 and 3, exterior bayonet slot links together or is integrally formed with handle, and has inside groove, inside groove and interior card
Outer groove cooperation in slot, this rotates outer groove around inside groove, so that the striker on inside and outside side bayonet slot generates not
Equidirectional power, to increase binding force, fixed water filling port.
Water injection pipe as shown in Figure 4 is mounted on wall according to process, and sensor transmits test data, judgement by data line
Termination condition is tested, and carries out data processing.
As shown in figure 5, the detailed process of description concrete infiltration in-site measurement installation.Inner card cage is divided into two parts, will
Sealing ring is entangled with water filling port, is loaded on both ends inner card cage, and tightening screw completes the fixation of water filling port and inner card cage；Exterior bayonet slot
It is divided into two parts, the outer groove in the inside groove and inner card cage of exterior bayonet slot is cooperated, then tightening screw, completes consolidating for outer side bayonet slot
