As shown in Figures 1 to 4：The dynamic water-proof experimental rig of the present embodiment, including accumulator 1 for water storage and be used for The pressing mechanism to be pressurizeed to the water in accumulator 1, the accumulator 1, which is provided with, to be used to spray the water after pressurization to ground 91 1a of spray orifice I and injection to metope 92 the 1b of spray orifice II；Spray orifice I is vertical or tilts towards ground；Spray orifice II is vertical or tilts Towards metope；Water in accumulator 1 is sprayed to ground 91 by the 1a of spray orifice I under the pressurization of pressing mechanism, passes through spray orifice II 1b sprays the water to metope 92, ejected and impinged upon so as to simulate the pressure that people's activity is formed on ground 91 and metope 92, Thus the stochastic and dynamic power that the activity of people under truth applies to house can be simulated when detecting house leak, makes detection more accurate Really, reality is more met；Solid arrow is to spray situation schematic diagram in Fig. 3.

In the present embodiment, the device also includes being used for the water circulating pump 2 that the water on ground 91 is evacuated to accumulator 1；Recirculated water Pump 2 directly can place or be fixed on ground 91, be connected between water circulating pump 2 and accumulator 1 by water pipe 21；Certainly, circulate The flowing of water should avoid the normal operation to pressing mechanism from impacting；The water for flowing to ground 91 is back to by water circulating pump 2 Accumulator 1 is reused, can effectively save water resource；The water of ground 91 is also strengthened it by the effect of water circulating pump 2 and disturbed Action is used, and has certain impact to ground 91 and metope 92, so as to improve the variable force applied to house；Fig. 3 is dotted arrow As water circulation schematic diagram.

In the present embodiment, the accumulator 1 includes the water tank 11 with water storage room 12, is provided with and opens positioned at the top of water storage room 12 Mouthful；The pressing mechanism include the case lid 3 that is adapted to water storage room 12 and for drive case lid 3 in water storage room 12 axially movable Drive component, the case lid 3 pressurizes during moving axially downwards to the water in water storage room 12；Water storage room 12 is storage The inner chamber of hydrophone 1, for water storage；Case lid 3 can close water storage room 12；In Fig. 2, axial direction is vertical direction；Using case lid 3 to water storage The water of room 12 is pushed, and its is simple and reasonable for structure, advantageously reduces product cost.

In the present embodiment, the drive component includes the electromagnet being located on accumulator 1 and is located on case lid 3 and electromagnet Magnet 42 corresponding to 41, the coiling group of the electromagnet 41 are connected by switching switch 5 with power supply, and 5 are switched by the switching Changing the sense of current causes electromagnet 41 to attract with the phase of magnet 42 or mutually repel；Electromagnet 41 is provided with protective housing, to keep away Exempt from that electric leakage accident occurs；Electromagnet 41 circumferentially can uniformly be located at the opening of water tank 11, and corresponding magnet 42 is located at the top of case lid 3 Portion；Electromagnet 41 can produce the magnetic force for attracting or mutually repelling with the phase of magnet 42 when being powered, so as to pick up case lid 3 or make case lid 3 move down, and case lid 3 pushes to the water of water storage room 12 during moving down；Power supply can be civil power, pass through wire 93 are connected.

In the present embodiment, the water tank 11 includes inner layer wall 13, midfeather 14 and the outer wall set gradually from the inside to the outside 15；First passage 16 is provided between the inner layer wall 13 and midfeather 14, the is provided between the midfeather 14 and outer wall 15 Two passages 17；The bottom surface of the inner layer wall 13, which is provided with, to be used to connect water storage room 12 and the first intercommunicating pore 13a of first passage 16, institute The top for stating midfeather 14 is provided with the second the intercommunicating pore 14a, the 1a of spray orifice I for being used for connecting first passage 16 and second channel 17 Located at the bottom surface of outer wall 15, the 1b of spray orifice II is located at the side of outer wall 15；First passage 16 and second channel 17 extend Flow path, allows the water to sufficiently to be pressurizeed；The first intercommunicating pore 13a is preferably located at the bottom center of inner layer wall 13, The second intercommunicating pore 14a is then circumferentially uniformly located at the top of midfeather 14.

In the present embodiment, the switching switch 5 be hilted broadsword double-gate switch structure, the switching switch 5 moved end 5a and its Two do not select connection to change the sense of current between the 5b of moved end by a drive rod 6；The drive rod 6 is actively installed on water tank 11 Moved end 5a upper and that 5 are switched with switching is connected；Buoyant member 7 is provided with the first passage 16, the buoyant member 7 floats on the water surface And drive rod 6 can be promoted to move upwards with the rising of water level, driving switching switch 5 during drive rod 6 moves upwards From one, to another, moved end 5b's moved end 5b does not connect moved end 5a；Moved end 5a is " knife " of hilted broadsword double-gate switch, not moved end 5b That is " lock " of hilted broadsword double-gate switch；For example, when the water level of water storage room 12 reaches 50cm, buoyant member 7 will touch drive rod 6, while with the rising of buoyant member 7, drive rod 6 is pushed up, with the rising of drive rod 6, moved end 5a and bottom it is motionless 5b is held to disconnect, electromagnet 41 is powered off, and case lid 3 will have the trend to fall, and moved end 5a is connected with the not moved end 5b on top again, this The electric current of Shi Tongxiang electromagnet 41 will be reverse, and electromagnet 41 will give the magnet 42 of lower section with downward repulsion at this moment case lid 3 The water that will be pressed down against in water storage room 12, the water in water storage room 12 is set quickly to cross the second intercommunicating pore 14a, last water will be from The 1a of the spray orifice I and 1b of spray orifice II sprays；As the water level decreasing 20cm in water storage room 12, due in first passage 16 and water storage room 12 Water larger difference in height be present, the liquid level in first passage 16 declines, and buoyant member 7 can also decline therewith, at this moment drive rod 6 by In the effect of gravity, also begin to fall, the not moved end 5b connections of moved end 5a and bottom, now electromagnet 41 can produce and magnet again Case lid 3 is attracted to the position of beginning, forms the change procedure of circulation by the gravitation that 42 phases attract, gravitation.

In the present embodiment, shower nozzle 8 is respectively connected with the 1a of the spray orifice I and 1b of spray orifice II；Can by the astriction of shower nozzle 8 Further improve the hydraulic pressure for spraying water；The top (one end outside) of the shower nozzle 8 is provided with the nozzle 81 of " ten " font, spray Mouth 81 is that two 120 ° of secter pat intersects " ten " shape, and shower nozzle 8 is divided into pintongs, can also make six valves or eight valves；Spray First 8 bottom is provided with the threaded portion 82 for being used for being threadedly coupled with the 1a of spray orifice I or the 1b of spray orifice II, is easily installed and dismantles；Shower nozzle 8 Middle part is provided with sealing ring 83, prevents water seepage.

In the present embodiment, the device also includes being used for the support frame 94 for supporting accumulator 1；Support frame 94 for example can be three pin Frame, accumulator 1 is propped into certain altitude.

Finally illustrate, the above embodiments are merely illustrative of the technical solutions of the present invention and it is unrestricted, although with reference to compared with The present invention is described in detail good embodiment, it will be understood by those within the art that, can be to the skill of the present invention Art scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solution of the present invention, it all should cover at this Among the right of invention.
