Abstract

The utility model relates to a glass fiber reinforced plastic underground oil tank with an internal and an external walls forming an interlayer. The utility model is provided for providing a liquid container, by which the internal and the external surfaces of a tank body can be prevented from occurring any corrosion; the leakage can be found out in real time; the transportation and the installation operation are convenient. The glass fiber reinforced plastic underground oil tank with an internal and an external walls forming an interlayer comprises a tank body, the external surface of which is provided with undulate reinforced ribs. The tank body is composed of glass reinforced plastic walls which form an interlayer, and the internal and the external layers of the glass reinforced plastic walls are made of glass fiber. The interlayer is poured and filled with detecting liquid used for detecting leakage. The upper side of the external wall of the tank body is provided with a liquid level sensor communicated with the interlayer.

Description

Has the glass fiber reinforced plastic buried tank that constitutes the interlayer inside and outside wall

The utility model belongs to liquid container, particularly a kind of glass fiber reinforced plastic buried tank with formation interlayer inside and outside wall.

The buried tank of commonly using with iron and steel material quality make in the majority.Corrode for anti-, the tank skin of steel design need be eliminated the male or female corrosion protection and handle.Yet, these corrosion protection are handled and can't be changed the essence that iron and steel is subjected to corrosion easily, because of the metal surface except simple oxidative phenomena, electrochemical reaction also is to cause underground cylinder of steel to quicken the one of the main reasons of corrosion, as long as there are negative and positive the two poles of the earth in cylinder of steel itself and near soil and are the electrolyte of rainwater, electrochemical reaction will take place, even cylinder of steel material or surface inequality, distortion, scratch, tank body flaw such as wound, also can quicken the corrosion of cylinder of steel.So,, can't change the essence of iron and steel easy-to-rust though various corrosion protection measure can slow down the speed of cylinder of steel corrosion.

On the mode of leaking hunting, the tank body of steel can only adopt dry type to leak hunting owing to can not contact aqueous vapor.Tank body with interlayer because of outer intensity a little less than, even can't adopt malleation to leak hunting.And that the reliability that dry type is leaked hunting not is one of percentage hundred is effective.Just be difficult for when leaking simultaneously finding that perhaps tank body and oil product produce when expanding with heat and contract with cold phenomenon when summer, winter, make the interior pressure change of interlayer and send false alarm as inside and outside wall; The reaction of leaking hunting is also rapid inadequately, just finds when often causing great harm to leak, and causes but pollute, and environmental protection is threatened.

The purpose of this utility model provide a kind of can prevent the inside and outside surface of tank body any corrosion takes place, in time find to leak, be convenient to transport and installation have a glass fiber reinforced plastic buried tank that constitutes the interlayer inside and outside wall.

The utlity model has appearance and have the tank body of waveform ribs; Tank body is by inside and outside two-layerly forming for the glass fiber reinforced plastic wall of glass fiber of constituting interlayer; The interlayer perfusion has been full of the detecting liquid that leaks usefulness for detecting, is provided with the LS that is communicated with interlayer in the tank wall upside.

Wherein:

The liquid level detecting device is provided with upper and lower detection lines.

The tank body profile is the cylindrical of two ends tool hemisphere end plate; Outer wall ribs and end plate are and the integrated integral body of outer wall.

Owing to the utlity model has the tank body that appearance has the waveform ribs; Tank body is by inside and outside two-layerly forming for the glass fiber reinforced plastic wall of glass fiber of constituting interlayer; The interlayer perfusion has been full of the detecting liquid that leaks usefulness for detecting, is provided with the LS that is communicated with interlayer in the tank wall upside.Can bear powerful pressure, also any erosion can not take place; In use, when when the inwall breakage leakage phenomenon being arranged, detecting liquid can infiltrate in the inwall, and the liquid level in the liquid level detecting device just can descend; When the outer wall breakage leakage phenomenon being arranged, detecting liquid can ooze out outside the outer wall, and the liquid level in the liquid level detecting device also can descend; If when the outer underground water level of tank body this moment was higher than the tank body top, underground water then can infiltrate in the interlayer, the liquid level in the LS is risen; No matter promptly the liquid level in the LS rises or descends, when it surpassed upper and lower detection lines, LS just can record and send alerting.Can not only prevent that the inside and outside surface of tank body from any corrosion taking place, in time find to leak, and be convenient to transportation and installation, thereby reach the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 1, the utlity model has tank body 10, its profile is the cylindrical of two ends tool hemisphere end plate 13, tank body 10 is by inside and outside two-layerly forming for the glass fiber reinforced

plastic wall

12,11 of glass fiber of constituting interlayer 15, its outer wall 11 and hemisphere end plate 13 are one-body molded and have waveform ribs 14, can bear powerful pressure.Any erosion can not take place in the glass fiber reinforced plastic material of making tank body 10 inside and

outside walls

12,11, therefore, needn't worry the corrosion that aqueous vapor causes, also needn't do any elimination male or female corrosion protection measure, corrosion takes place if having slight collision or scratch also not to worry the meeting deface, and weight is lighter, no matter transportation or installation are all quite convenient.And glass fiber reinforced plastic is not had electric conductivity, can not be subjected to the influence of the grounding wire or the metal pipe line of adjacent structure, and it is safer to be used to store oil plant.

As shown in Figure 2, the inwall 12 of

tank body

10 and 15 perfusions of the interlayer between the outer wall 11 have been full of the detecting liquid 16 that leaks usefulness for detecting, be provided with the LS 17 that is communicated with interlayer 15 in tank body 10 outer walls 11 upsides, according to connecting pipe principle, liquid level in the LS 17 is relevant with the amount of detecting liquid 16 in the interlayer 15, if the amount of detecting liquid 16 changes, liquid level also can change thereupon in the LS 17, at any time monitor the liquid level of detecting liquid 16 in the interlayer 15, make and to make all 360 ° of round-the-clock leakage monitorings to inwall 12, outer wall 11.LS 17 is provided with upper and lower detection lines 171,172, is higher than detection lines 171 or is lower than detection lines 172 down if the generation leakage changes liquid level, just records and send alert news at once.

As shown in Figure 3, in use, when when inwall 12 breakages leakage phenomenon being arranged, detecting liquid 16 can infiltrate in the inwalls 12, and the liquid levels in the liquid level detecting device 17 just can descend.As shown in Figure 4, when when outer wall 11 breakages leakage phenomenon being arranged, detecting liquid 16 can ooze out outside the outer wall 11, and the liquid levels in the liquid level detecting device 17 also can descend; But as shown in Figure 5, if when the outer underground water levels of tank body 10 this moment are higher than tank body 10 tops, underground water then can infiltrate in the interlayer 15, and the liquid levels in the LS 17 are risen.No matter promptly the liquid levels in the LS 17 rise or descend, when it surpassed upper and lower detection lines 171,172, LS 17 just can record and send alerting.
