Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

A hydraulic hose diaphragm pump 100 further comprising: a diaphragm assembly mechanism 30. The diaphragm assembly mechanism 30 is connected between the piston post 20 and the pump body 10.

The diaphragm assembly mechanism 30 includes: a bellows hose 31, a diaphragm body 32 and a fixed coupling ring 33. A bellows hose 31 is connected to the bottom port of the pump body 10. A diaphragm body 32 is attached to the upper end of the bellows hose 31, and the diaphragm body 32 closes the upper end of the bellows hose 31. The fixed connection ring 33 is fixedly connected to the upper end edge of the bellows hose 31, and the fixed connection ring 33 is fixedly connected with the piston post 20.

The combination of the diaphragm body 32 and the bellows 31 isolates the inner wall of the pump body 10 and the piston post 20 from the fluid transported in the main transfer tube 40, thereby preventing the transported fluid from being corrosive and damaging the inner wall of the pump body 10 and the piston post 20. And when the piston column 20 reciprocates up and down, the liquid conveyed in the main conveying pipe 40 is pressurized by the diaphragm body 32, so that the conveying is convenient. In addition, the corrugated expansion hose 31 expands and contracts in the process, so that the diaphragm body 32 is prevented from being broken due to the fixed middle stretching edge.

A hydraulic hose diaphragm pump 100 further comprising: a rupture detection sensing mechanism 50. The breakage detection sensing mechanism 50 includes: a ring-shaped storage cylinder 51, a liquid sensing switch 52 and a signal lamp 53.

A signal lamp 53 is correspondingly mounted to the bottom end of the ring-shaped storage cylinder 51, and the signal lamp 53 is electrically connected to the liquid sensing switch 52.

When the bellows 31 or the diaphragm 32 is broken to leak the liquid, the leaked liquid flows to the bottom of the pump body 10. At this time, the liquid inevitably flows into the inner cavity of the annular storage cylinder 51, and then the liquid induction switch 52 induces the liquid to operate the signal lamp 53, so that the related staff is prompted to carry out maintenance conveniently.

The breakage detection sensing mechanism 50 further includes: for guiding leakage liquid into an annular groove 54 in the annular storage cylinder 51. An annular recess 54 opens at the inner wall of the pump body 10 at the location of the upper end of the annular storage cylinder 51.

The annular storage cylinder 51 is a transparent cylinder body, which is convenient for external direct observation to see whether liquid leaks and flows in.

The diaphragm assembly mechanism 30 further includes: the connecting ring 34 and the connecting sleeve 35 are embedded. The fitting connection ring 34 is fixedly connected to the bottom edge of the bellows 31, and the fitting connection ring 34 is fitted to the inner bottom of the pump body 10 while the fitting connection ring 34 is fixedly connected to the inner bottom of the pump body 10 by bolts. The connecting sleeve 35 is sleeved on the piston post 20, and the connecting sleeve 35 is fixedly connected to the piston post 20 through a fixing bolt, and meanwhile, the connecting sleeve 35 is fixedly connected with the fixing connecting ring 33.

When the bellows 31 or the diaphragm body 32 is detected to be cracked and leaked, the housing of the pump body 10 is separated, then the fixing bolt between the embedded connecting ring 34 at the bottom of the bellows 31 and the pump body 10 is detached, and the bolt between the connecting sleeve 35 and the piston column 20 is detached at the same time. Therefore, the whole diaphragm combination mechanism 30 is disassembled and is convenient to replace.

The linkage frame 62 is horizontally and fixedly connected to the lower end of the electric telescopic rod 61. The jack 63 is vertically fixedly connected to the middle upper side of the link frame 62. The movable closing block 64 is fixedly connected to the upper end of the push rod 63, and the movable closing block 64 is inserted to the bottom middle position of the main transferring pipe 40. The rotary shutters 67 are rotatably connected to the inner side of the main transfer pipe 40 in a left-right pair and are distributed on both sides below the connection position of the pump body 10, while the inner side wall of the main transfer pipe 40 is provided with valve seals fitted to the rotary shutters 67. The ball screw 66 is vertically connected below the position of the rotary shutter 67, and the ball screw 66 rotates coaxially with the rotary shutter 67. The screw rod sleeves 65 are fixedly connected to two ends of the linkage frame 62, and the screw rod sleeves 65 are sleeved on the ball screw 66 in a matching mode.

When the liquid sensing switch 52 detects liquid, that is, a leakage occurs in the diaphragm assembly 30 inside the pump body 10, the liquid sensing switch 52 triggers the electric telescopic rod 61 to contract. The electric telescopic rod 61 drives the mandril 63 to jack up through the linkage frame 62, so that the movable closing block 64 is lifted. After the movable sealing block 64 is lifted, the sidewall of the main conveying pipe 40 at the original position is opened, so that the liquid in the pump body 10 can be conveniently discharged, and the diaphragm combination mechanism 30 can be conveniently maintained subsequently. Meanwhile, when the linkage frame 62 is lifted, the screw rod sleeves 65 at the two ends are lifted, and the ball screw 66 which is matched and connected in the process is rotated. The rotary ball screw 66 drives the connected rotary gate plate 67 to rotate, when the electric telescopic rod 61 is contracted to the limit position, the rotary gate plate 67 just rotates to the cross section position of the main conveying pipe 40, namely, the two ends of the main conveying pipe 40 are separated from the space where the pump body 10 is located, and the liquid material waste caused by the fact that liquid is conveyed through the pump body 10 is avoided.

The movable end of the conductive blade 731 is connected to the fixed conductive post 732, and the conductive blade 731 and the fixed conductive post 732 are connected in series to the power circuit of the pump body 10 through a conductive wire.

When the electric telescopic rod 61 contracts due to the leakage of the diaphragm assembly mechanism 30, the electric telescopic rod 61 drives the first convex top block 74 to lift up through the linkage frame 62. The first bump 74 finally penetrates through the through hole 72 to lift the conductive cutter body 731, so that the conductive cutter body is separated from the fixed conductive column 732, and the power circuit of the pump body 10 is disconnected, and the shutdown is realized.

The power cutoff mechanism 70 further includes: an insulating elastic diaphragm 75 and a second dome 76. An insulating elastic diaphragm 75 is hermetically attached at the through-hole 72.
