Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
Embodiment 1
As depicted in figs. 1 and 2, a kind of automatic control dam hydraulic pressure force checking device, including seal casinghousing 15, the sealing
Shell 15 is circle or rectangular, and one end is equipped with the strainer 11 for blocking weeds, and the other end is equipped with dismountable close
Big envelope head 5, sealing pullover 5 movable can be dismantled, and replacement easy to repair in this way seals and is additionally provided with overturning sealing cover at the top of pullover 5
3.15 end strainer of seal casinghousing, 11 side is equipped with fixation and connects block 16;Fixation connects block 16 and is linked together with seal casinghousing 15, can weld
Fixed, size is to block the half of 15 port of seal casinghousing.
Hydraulic cylinder 6 is mounted in the apparatus container 8 inside seal casinghousing 15, and the telescopic rod 7 of hydraulic cylinder 6 is pierced by device
Container 8, telescopic rod 7, which is pierced by apparatus container 8, is additionally provided with rubber seal 9, can prevent apparatus container 8 from intaking in this way.It is flexible
Its top of bar 7, which is equipped with, matches the work movable contact block 12 that strainer 11 is blocked in sealing with the fixed block 16 that connects;It is fixed to connect block 16 and activity
Connecing block 12 cooperates sealing means to be stepped groove cooperation sealing.Sealing pullover 5 is equipped with connecing of being connected to in seal casinghousing 15 above
First 4, pressure gauge 2 is mounted on the water pipe 17 being connected to connector 4, and 17 water outlet of water pipe is additionally provided with solenoid valve 1, in order to anti-
It is only blocked for a long time using deposited mud in seal casinghousing 15, is additionally provided on connector 4 and is directly connected to in seal casinghousing 15
The outlet pipe 14 for cleaning, two (not shown) of solenoid valve is installed on outlet pipe 14.By periodically sealing cleaning, protect
The accuracy of water-pressure survey is demonstrate,proved.Two (not shown) of solenoid valve, solenoid valve 1, hydraulic cylinder 6 and pressure gauge 2 pass through number
Computer control system is connected according to line, computer control system controls dam sluice gate closing device simultaneously.
Based on above-mentioned apparatus, the invention also provides a kind of automatic control dam water pressure detection arrangement monitors method, packets
Include following steps:
(1) when dam is built, the present apparatus is fixed by design monitoring point (such as Fig. 3 institute when dam body 20 is poured
Show), it is cast on dam body, strainer 11 is laid in the water storage side of dam;
(2) pressure gauge 2, hydraulic cylinder 6, solenoid valve 1 and two (not shown) of solenoid valve are connected into meter by data line
Machine control system is calculated, computer control system controls dam sluice gate closing device simultaneously;
