Description
Technical field
The utility model belongs to deep-well pump technical field, refers in particular to a kind of water pump interface water-tight device.
Background technology
The maximum feature of deep well pump is to be formed integrally motor and pump, and it is to immerse in underground water well to carry out suction and defeated
A kind of pump of water is sent, is widely used in farmland discharging-irrigating, industrial and mining enterprises, urban water supply and sewerage and sewage disposal etc..At present on the market
Deep well pump interface line mostly be it is fixed, so run into some depth it is deeper draw water region when be accomplished by connecing deep well pump
Mouth line is cut off and connects longer electric wire, then is wrapped up two sections of cables with insulating tape.Such mode is present
Following some deficiencies：1. insulating tape easy ageing failure during long-term use, once cable can in water
It can leak electricity, the life security to workmen threatens, in addition once leaking electricity, it is possible to situation about tripping,
So cannot normal construction.2. reply is different draw water depth when, need to take apart interface often and connect different length
The electric wire of degree is powered, using cumbersome.
The content of the invention
The utility model is in view of the above-mentioned problems, providing one kind can conveniently disconnect, and effectively sealing prevents drain conditions
The water pump interface water-tight device of generation.
What the purpose of this utility model was realized in：
Sealing is formed on a kind of water pump interface water-tight device, including water pump interface and power connection, the water pump interface
Connection jaws are provided with body, seal, the power connection forms in annular seal space, annular seal space and is provided with cable connector；It is described
Power connection is provided with screwed hole, and the edge of power connection upwardly extends to form one section of sealing gear edge, the water pump interface
It is additionally provided with diaphragm seal, diaphragm seal and forms through hole, and diaphragm seal forms flat mouth sealing with sealing gear edge.
In above-mentioned water pump interface water-tight device, the upper end of the annular seal space is also molded a limited step, the sealing
The expansion software coordinated with the limited step is also formed on piece positioned at the position of seal outer wall.
In above-mentioned water pump interface water-tight device, the height of the expansion software is higher than the height of limited step.
In above-mentioned water pump interface water-tight device, tread plate is formed on the power connection.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：
1. water pump interface of the present utility model is arranged on the inside of water pump, the seal on water pump interface by connection jaws and
Cable connector on the annular seal space of power connection is fixed together, first of the sealing of annular seal space and seal formation, secondly
The diaphragm seal of water pump interface is fixed on power connection with bolt again, diaphragm seal reaches the with sealing gear along flat mouth sealing is formed
Two layers of sealing defence line.Accordingly even when when water pump works under the bottom, who also be difficult to from external penetration to inside with cable connector or
Connection jaws, which are in contact, causes electric leakage.
2. expansion software of the present utility model during diaphragm seal and power connection are tightened can by lasting pressure so as to
Deform upon, and limited step is filled full, form three seals defence line.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings,
As shown in Figure 1, Figure 2 and Figure 3, a kind of water pump interface water-tight device, including water pump interface 1 and power connection 2, it is described
Formed on water pump interface 1 and connection jaws 4 are provided with seal 3, seal 3, the power connection 2 forms annular seal space 5, close
Cable connector 6 is provided with envelope chamber 5；The power connection 2 is provided with screwed hole 7, and the edge of power connection 2 is upwardly extended
One section of sealing gear is formed along 8, the water pump interface 1 is additionally provided with diaphragm seal 9, diaphragm seal 9 and forms through hole 10, and seals
Piece 9 forms flat mouth sealing with sealing gear along 8.Water pump interface 1 is inserted by the formation of cable connector 6 of connection jaws 4 and power connection 2
Connect, the side wall of seal 3 and first of sealing defence line exclusion of water of side wall formation of annular seal space 5 are externally entering to inside, it is to avoid
Leak electricity, after seal 3 and the installation grafting of annular seal space 5, the diaphragm seal 9 on water pump interface 1 connects with the formation of power connection 2
Touch, and the edge slot that seal 3 and annular seal space 5 are contacted is covered, and then forms flat mouth sealing along 8 with sealing gear again, most
Through hole 10 and screwed hole 7 are tightened with bolt afterwards, such diaphragm seal 9 and sealing gear are formed the second of the water-tight device along 8
Road seals defence line.
As shown in figure 1, in above-mentioned water pump interface water-tight device, the upper end of the annular seal space 5 is also molded a limiting stand
