[0002] The temperature inside large-volume concrete varies greatly, and temperature deformation often generates temperature stress due to boundary or internal constraints, which leads to cracks, destroys the integrity of the building, and affects the life and safety of the building. Since temperature deformation accounts for a large proportion of the total deformation of the building caused by various factors, it needs to be quantitatively studied when evaluating the safety of the building.

[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0021] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0022] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0023] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0024] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0026] The concrete temperature measuring device provided by the present invention is now described.

[0027] like Figure 1 As shown, the first embodiment of the present invention provides a concrete temperature measuring device, including a corrugated pipe 10, an anti-rust component, a mounting frame 60, a temperature sensor 70 and a data wire 80.

[0028] The rust-proof component is arranged on the bellows 10 .

[0029] The mounting bracket 60 is disposed at one end of the corrugated tube 10 .

[0030] The temperature sensor 70 is fixed in the corrugated pipe 10 through the mounting frame 60 to detect the temperature of concrete.

[0031] The data wire 80 is inserted into the corrugated tube 10 , and one end of the data wire 80 is connected to the temperature sensor 70 , and the other end of the data wire 80 is inserted from the other end of the corrugated tube 10 .

[0032] Bellows refers to a tubular elastic sensitive element connected by foldable corrugated sheets along the folding and stretching direction. Bellows are widely used in instruments and meters. Their main purpose is to be used as measuring elements of pressure measuring instruments to convert pressure into displacement or force. The bellows has a thinner wall and higher sensitivity, with a measuring range of tens of Pa to tens of MPa. Its open end is fixed, the sealed end is in a free state, and an auxiliary spiral spring or reed is used to increase elasticity. When working, it stretches along the length of the tube under the action of internal pressure, causing the movable end to produce a displacement that is related to the pressure. The movable end drives the pointer to directly indicate the size of the pressure. Bellows are often combined with displacement sensors to form pressure sensors with output as electrical quantity, and are sometimes used as isolation elements. Since the extension of bellows requires a larger volume change, its response speed is lower than that of Bourdon tubes. Bellows are suitable for measuring low pressures.

[0033] The bellows is a metal bellows, preferably a steel bellows. The metal bellows is mainly used to compensate for pipeline thermal deformation, shock absorption, and absorption of pipeline settlement deformation, and is widely used in petrochemical, instrumentation, aerospace, chemical, electric power, water conservancy, metallurgy and other industries. The metal bellows has good thermal conductivity and is easy to shape, which can facilitate the layout and use of the temperature sensor 70.

[0034] However, due to the setting of the bellows, the temperature sensor 70 and the data conductor 80 are no longer completely wrapped by concrete, and one end of the bellows 10 is open, which makes it easy for water to enter during the concrete curing process. Under water and alkali corrosion, the bellows is prone to rust, affecting the use of the temperature sensor 70 and the data conductor 80. Therefore, the provision of an anti-rust component can prevent rust inside the bellows, which is beneficial to ensuring the effectiveness of the temperature sensor 70 and the data conductor 80.

[0035] In addition, after confirming that the temperature sensor 70 and the data wire 80 are not damaged and completing the main temperature measurement work of concrete molding, the inside of the bellows 10 can also be sealed by injecting grout into the bellows 10 as needed. Since the corrugations of the bellows have strong friction, the grouting body is relatively stable and will not affect the overall quality of the concrete.

[0036] Compared with the prior art, the concrete temperature measuring device provided in the present embodiment can be used in a manner that the bellows 10 can be bent into a desired shape as needed to facilitate positioning of the temperature sensor 70 at a desired position. Thereafter, during the pouring of concrete, the bellows 10 will protect the temperature sensor 70 and the data wire 80, thereby greatly reducing the possibility of damage to the temperature sensor 70 and the data wire 80. Furthermore, even if the temperature sensor 70 and the data wire 80 are damaged, they can be remedied by placing a temperature sensor 70 with a data wire into the bellows 10 again and fixing them with glue, thereby ensuring the detection of the concrete temperature and thus ensuring the molding quality of the concrete.

[0037] like Figure 1 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0038] The mounting bracket 60 is an elastic bracket, the outer side of which is embedded in the corrugations of the inner wall of the corrugated tube 10 , and the inner side of which is interference fit with the temperature sensor 70 .

[0039] The mounting bracket 60 may be made of elastic materials such as rubber and silicone, or may be made of an elastic structure. The installation of the temperature sensor 70 may be facilitated by providing such a mounting bracket 60 .

[0040] like Figure 1 and Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0041] The anti-rust component includes a housing sleeve 20, a deoxidizing filler 30, a closing sheet 40 and an inner support ring 50. The housing sleeve 20 is arranged in at least one trough of the inner wall of the bellows 10. The deoxidizing filler 30 is filled in the housing sleeve 20 to absorb oxygen. The closing sheet 40 is a galvanized component or a zinc component, which is arranged on the side of the housing sleeve 20 facing away from the bottom of the trough, and the edges on both sides abut against the inner wall of the bellows 10 to limit the housing sleeve 20 in the trough. The inner support ring 50 is arranged on the inner side of the closing sheet 40 to support the closing sheet 40 so that the edges on both sides of the closing sheet 40 abut against the outer wall of the bellows 10.

[0042] In the early stage of the use of the bellows, the deoxidizing filler 30 installed in the containing sleeve 20 is pressed and bound in the trough outside the bellows 10 by the cooperation of the closing piece 40 and the inner support ring 50, and the vibration on the bellows 10 is absorbed by the deoxidizing filler 30 to reduce the noise transmitted to the outside. At the same time, the containing sleeve 20 can isolate the deoxidizing filler 30 from the outside in the early stage of use. At this time, the anti-oxidation property of the bellows 10 is guaranteed by the electrochemical corrosion of the closing piece 40; and after the seamless bellows has been used for a certain period of time, under the action of long-term geological vibration or corrosion, with the electrochemical consumption of the closing piece 40 and the aging and damage of the containing sleeve 20, the deoxidizing filler 30 contacts with the outside air and absorbs oxygen in the air, so that the bellows 10 is in a low-oxygen environment. Since a large amount of deoxidizing filler 30 can be accommodated in the containing sleeve 20, it can be ensured that the bellows 10 can still have a long period of anti-oxidation property after the zinc on the closing piece 40 is consumed, thereby effectively extending the service life of the seamless bellows.

[0043] The inner support ring 50 needs to be made of a relatively strong and corrosion-resistant material, and its corrosion resistance should be higher than that of the sealing plate 40 to avoid oxidation corrosion by the gas or fluid inside the pipeline.

[0044] In actual use, a set of accommodating sleeves 20 , deoxidizing fillers 30 , sealing sheets 40 and inner support rings 50 may be provided in any or every trough of the bellows 10 and inside and outside the bellows 10 as needed.

[0045] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0046] The closing piece 40 is provided with a spike cone 42 on one side facing the housing sleeve 20, and a zinc droplet 43 is provided at the end of the spike cone 42. The zinc droplet 43 is spherical at the end of the spike cone 42 and can wrap the tip of the spike cone 42. The zinc droplet 43 will be gradually consumed in the long-term electrochemical corrosion process. If the oxidation speed of the closing piece 40 is too fast, the zinc droplet 43 will be consumed before the housing sleeve 20 has time to age and break, and the tip of the spike cone 42 will be exposed, and the housing sleeve 20 will be punctured under the vibration of geological changes, so that the deoxidizing filler 30 therein is in contact with the outside air, thereby absorbing the oxygen therein and reducing the oxidation of the bellows.

[0047] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0048] The piercing cone 42 is provided with a gas guiding groove 44 so as to facilitate gas to enter the containing sleeve 20 after the containing sleeve 20 is pierced.

[0049] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0050] The cross section of the closing piece 40 is arc-shaped, and the thickness gradually increases from the edges on both sides to the middle. When used for a long time, the edges of the closing piece 40 that contact the bellows 10 are consumed first, and under the tightening action of the inner support ring 50, the unconsumed edges of the closing piece 40 are in contact with the bellows 10, thereby avoiding the rapid loss of strength caused by consumption in the middle of the closing piece 40.

[0051] A specific implementation of a concrete temperature measuring device provided by the present invention based on the above implementation is as follows.

[0052] V-shaped notches are provided at intervals on both side edges of the closing piece 40 to facilitate bending the closing piece 40 into an arc-shaped structure and to prevent the two side edges from being bent and stacked due to stress concentration.

[0053] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0054] The inner support ring 50 is a corrugated elastic structure so as to provide a relatively long-lasting elastic force to the closing piece 40 .

[0055] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0056] The closing piece 40 is provided with a limiting groove for limiting the inner support ring 50 to prevent the inner support ring 50 from slipping.

[0057] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0058] In order to prevent the edges on both sides of the closing piece 40 from scratching the bellows 10 , a curling structure may be provided on the edges on both sides of the closing piece 40 .

[0059] like Figure 2 As shown, the present invention provides a specific implementation of a concrete temperature measuring device based on the above implementation.

[0060] In order to enhance the inner support effect of the inner support ring 50 , an inner support structure may be further provided on the inner support ring 50 .

[0061] In some specific embodiments, the inner support structure may include a connecting ear provided on the inner support ring 50 and a bolt passing through the connecting ear.

[0062] A specific implementation of a concrete temperature measuring device provided by the present invention based on the above implementation is as follows.

[0063] The housing sleeve 20 is a plastic hose; the deoxidizing filler 30 is a deoxidizer with a loose structure.

[0064] A specific implementation of a concrete temperature measuring device provided by the present invention based on the above implementation is as follows.

[0065] The deoxidizing filler 30 is a mixture of filamentary zinc scraps, detergent and water. The filamentary zinc scraps have a certain energy dissipation and sound absorption effect. The detergent and water can remove the oil stains on the filamentary zinc scraps after mixing, so that the filamentary zinc scraps can combine with oxygen more quickly in the later use. If the zinc scraps are filled enough, the bellows can be used for decades.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
