Description

A kind of double-wall storage tank with wall body Safety check-up device

[technical field]

The utility model relates to the checking system in a kind of storage tank, refers in particular in double-wall storage tank a kind of checking system that can detect that wall body breaks.

[background technology]

Buried storage tank is one of major way of oil product storage, current buried petrol storage tank is mainly divided into individual layer storage tank and double-wall storage tank two kinds, wherein the breakage of individual layer Corrosion of Tanks is easily permeated afterwards, leak, soil and groundwater is caused to pollute, also waste the oil body resource in storage tank, therefore, be in the patent document of 201220695881.X in the such as patent No., have developed a kind of double-wall storage tank especially, this double-wall storage tank is primarily of top tank structure, hollow sandwich composition between tank wall and inside and outside wall, while reinforcement storage tank wall body intensity, and in interlayer, be provided with leak detection sensor, when after inner wall layer or outer wall layer generation crackle, liquid in tank or outside tank will leak in interlayer, after detecting when leak detection sensor will and alarm, user is allowed to carry out in time processing to eliminate safe hidden trouble, avoid environment.But the installation of leak detection sensor also can only be arranged several check points to install in the interlayer of double-walled body, as " three-dimensional hollow supervisory layers is infiltrate the hollow fabric layer having resin " mentioned in patent document, although make three-dimensional hollow supervisory layers inner space be continuous and do not disconnect to a certain extent, but the characteristic of resin fabric makes the space in three-dimensional hollow supervisory layers become narrow and dense, after wall body breaks, oil body in storage tank is from interior outflow, extremely difficulty empty monitoring intrastratal flowage in three dimensions, when that of place of breaking does not arrange leak detection sensor, just be difficult to detected by the leak detection sensor that is positioned on other check points, only have when oil body seepage to a certain degree and be flowing on check point time can be detected by leak detection sensor, like this, the sensitieness of detecting device and capability of reaction is just made greatly to reduce, often can not detect the very first time and feed back, the hysteresis quality of life period, also for the maintenance of maintainer afterwards adds difficulty.

[utility model content]

The technical problems to be solved in the utility model overcomes above-mentioned defect, provides a kind of rational in infrastructure, can detect the double-wall storage tank whether wall body breaks in real time.

For solving the problem, the technical scheme that the utility model adopts is:

With a double-wall storage tank for wall body Safety check-up device, include the storage tank body become by inside and outside two layers of walls system and the oil body leak detection apparatus be located on storage tank; Splinting layer is provided with between described inside and outside wall body, described splinting layer comprises a plane plane plate and one-body molded several spacer bodies on plane plate one side, all spacer bodies are all form to a direction depression and be evenly distributed on clamping plate on plane plate, the plane side of described splinting layer is fitted on a wherein wall body of inside and outside wall body, its side being provided with spacer body is fitted on another wall body of inside and outside wall body, forms continuous continual cavity between that side of described splinting layer band spacer body and its wall body be close to; Described oil body leak detection apparatus is level sensor, and described level sensor to be arranged on storage tank outer wall and to be linked into below it in this cavity and to detect in real time.

In the improvement project to above-mentioned a kind of double-wall storage tank with wall body Safety check-up device, the side of the plane of described splinting layer and outer wall are fitted, and that side and the inner wall of its band spacer body are fitted.

Owing to have employed technique scheme, compared with prior art, the utility model is the double-walled body storage tank of band splinting layer, and the structure of this splinting layer guarantee self-strength and stressed while, in also ensure that, cavity between outer two wall bodies is conducting and does not disconnect, thus ensure that the liquid communication in cavity is smooth and easy and without hindrance, moreover, it adopts level sensor to detect, liquid like this in cavity increases or reduces and can both very sensitively detect quickly, there is not the problem of hysteresis quality, simple and reasonable, efficiently solve the problem that real-time monitor and detection storage tank wall body breaks.

[detailed description of the invention]

The utility model is a kind of double-wall storage tank with wall body Safety check-up device, as shown in Figures 1 to 4, includes the storage tank body 10 be made up of inside and outside two-layer wall body 11,12 and the oil body leak detection apparatus 20 be located on storage tank 10, in described, outer wall 11, splinting layer 30 is provided with between 12, described splinting layer 30 comprises a plane plane plate 31 and one-body molded several spacer bodies 32 on plane plate 31 1 side, all spacer bodies 32 are all form to a direction depression and be evenly distributed on plane plate 31 on plane plate 31, in the plane side of described splinting layer 30 is fitted in, outer wall 11, on a wherein wall body of 12, in its side being provided with spacer body 32 is fitted in, outer wall 11, on another wall body of 12, continuous continual cavity is formed between that side with spacer body 32 of described splinting layer 30 and its wall body be close to, described oil body leak detection apparatus 20 is level sensor, and described level sensor to be arranged on storage tank 10 outer wall and to be linked into below it in this cavity and to detect in real time.

When making storage tank 10, need first interior, outer wall 11, liquid is injected in the cavity communicated between 12, like this, the level sensor be positioned in storage tank outer wall 12 just detects certain liquid level information, after the inner wall 11 of storage tank 10 breaks, oil in storage tank 10 leaks, be injected in the liquid in cavity, so just make the liquid accretion of stock in cavity, liquid level rises, at this moment level sensor just can detect from do not reveal before the different information of liquid level, and feed back away immediately, service personnel just can organize maintenance after learning this information, equally, after the outer wall 12 of storage tank 10 is broken, no matter be that the liquid that earthing water flow in cavity or in cavity flows out to underground, the liquid level in cavity all can change, thus detected by level sensor, service personnel is learnt and organizes maintenance.

Because storage tank 10 is buried in underground, sub-surface is huge to the pressure of storage tank 10, like this, in the present embodiment, as shown in Fig. 1,2,4, side and the outer wall 12 of the plane of described splinting layer 30 are fitted, that side and the inner wall 11 of its band spacer body 32 are fitted, like this, after soil layer is delivered to splinting layer 30 to storage tank outer wall 12 applied pressure, just can be born by splinting layer 30 and share pressure.

Above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit, although execute example with reference to previous examples to be described in detail the utility model, those of ordinary skill in the art is to be understood that, it is according to can modifying to the technical scheme that foregoing embodiments is recorded, or equivalent replacement is carried out to its portion of techniques feature, and these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the category of technical solutions of the utility model.
