Further, it is additionally provided with the second seal chamber on end cap, the second cylinder is equipped with compatible with the second sealing cavity the
Three sealing cavities are additionally provided with the 4th sealing cavity on the second cylinder.
The deficiencies in the prior art are compared, advantageous effect caused by technical solution provided by the utility model：When in use,
Connector cover is connected with terminal box by screw, is additionally provided in terminal box for placing rubber seal mounting groove, is played close
Envelope acts on, and water is avoided to enter from gap, while the presence of storage cavity so that by a small amount of liquid being entered storage can be flow to
In water cavity, avoid the problem that water enters cavity along cable and occurs so as to cause coil burnout, intercommunicating pore and mounting hole are equal
Equipped with internal thread, therefore intercommunicating pore and mounting hole can further be sealed by cable feedthrough, even if storage cavity
Inside there is more water but also water will not enter from intercommunicating pore in cavity, lift-off seal effect, cable is from outside through peace
Dress hole simultaneously enter in seal chamber, the cable in seal chamber is wrapped up by fluid sealant, fluid sealant include the first sealant layer,
Second sealant layer and third sealant layer are wrapped in cable in the first sealant layer, are wrapped in the second sealant layer
Except the cable core of cable external protection, the third sealant layer is wrapped in the conduction for eliminating cable core protective layer
Body, such as copper wire etc., therefore can effectively avoid the problem that coil damage caused by cable water inlet occurs, meanwhile, with first
The presence for the end cap, the second cylinder being connect with end cap seal that cylinder is tightly connected is but also water will not be empty from entering elsewhere
Chamber so that waterproof effect is more preferable.

Specific implementation mode
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
It selects embodiment to be merely to illustrate and explain the present invention, is not used to limit the utility model.
- Fig. 6 is described further the utility model referring to Fig.1.
A kind of multi-sealing structure of submersible pump, including the first cylinder 1,12 and of terminal box that is located on the first cylinder 1
The second cylinder 4 that cable 6 further includes the end cap 3 being tightly connected with the first cylinder 1, is tightly connected with end cap 3, the first cylinder 1
It is interior to be equipped with cavity 11, it is additionally provided with storage cavity 121 in terminal box 12, sealing 122, sealing are additionally provided in storage cavity 121
122 are equipped with intercommunicating pore 123, and intercommunicating pore 123 is connected to cavity 11, and internal thread is equipped at intercommunicating pore 123, is additionally provided in terminal box 12
Connector cover 2, connector cover 2 are equipped with seal chamber 21, fluid sealant 5 are equipped in seal chamber 21, is additionally provided on connector cover 2 for making
The mounting hole 22 that cable 6 passes through, mounting hole 22 are equipped with internal thread；When in use, connector cover 2 and terminal box 12 pass through spiral shell
Nail is connected, and is additionally provided in terminal box 12 for placing rubber seal mounting groove 124, plays sealing function, avoids water from connecing
At the gap of 12 junction of wire box lid 2 and terminal box enter, while the presence of storage cavity 121 make even if by a small amount of liquid into
Entering can also flow in storage cavity 121, avoid the problem that water occurs into cavity so as to cause coil burnout along cable 6,
Intercommunicating pore 123 and mounting hole 22 are equipped with internal thread, therefore can be carried out to intercommunicating pore 123 and mounting hole 22 by cable feedthrough
Further sealing, even if there are more water but also water will not enter cavity 11 from intercommunicating pore 123 in storage cavity 121
