[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] As attached Figure 1 ,2 As shown, a steam pipeline safety alarm device involved in the utility model includes a pressure detection unit 1, a pipeline deformation detection unit 2, and a data processing and transmission unit 3.

[0019] The detection unit 1 and the pipeline deformation detection unit 2 perform detection based on pressure sensors. The pressure sensors are electrically connected to the data processing and transmission unit 3. The data processing and transmission unit 3 has data acquisition, data transmission, and power supply functions, and generally includes batteries and integrated circuit boards. Its specific structure and the selection and connection method with the pressure sensor are conventional knowledge in the field.

[0020] The data processing and transmission unit 3 and the pressure detection unit 1 and the pipeline deformation detection unit 2 can be one-to-one or one-to-many, that is, one pressure detection unit 1 or pipeline deformation detection unit 2 corresponds to one data processing and transmission unit 3, and multiple pressure detection units 1 and / or pipeline deformation detection units 2 correspond to one data processing and transmission unit 3.

[0021] As attached Figure 2 , 3 As shown, the pressure detection unit 1 includes a lower valve body 11, an upper valve body 12, a central pressure transmission unit 13, and a pressure detection unit 14. The lower valve body 11 is a two-way structure, and its two ends are connected to the steam pipe through flanges. A valve chamber x1 is arranged in the center. The upper valve body 12 is arranged above the lower valve body 11 to close the valve chamber x1. The central pressure transmission unit 13 is fixed at the opening of the upper valve body 12, and includes a pressure-bearing layer 131, a central pressure transmission shell 132, and a pressure transmission layer 133. The central pressure transmission shell 132 is a tubular structure with one end closed and the other end open. A protrusion is arranged at the lower end (open end), which cooperates with the groove at the opening of the upper valve body 12 to achieve secure fixation. A pressure-bearing layer 131 is arranged at the opening of the lower end of the central pressure transmission shell 132, and the upper end is an upper sealing plate 1322 with a cylindrical protrusion 1321 in the center. A through hole is arranged on the top surface of the cylindrical protrusion 1321, and a pressure transmission layer 133 is arranged at the through hole. The central pressure-transmitting shell 132 , the pressure-bearing layer 131 , and the pressure-transmitting layer 133 enclose a closed space, and the space is filled with a pressure-bearing liquid 134 .

[0022] A pressure detection unit 14 is disposed on the top surface of the pressure transmission layer 133 , and the top surface of the pressure detection unit 14 is fixedly connected to the inner top surface of the lower valve body 11 .

[0023] The pressure detection unit 14 is used to detect the pressure change caused by the deformation of the pressure transmission layer 133, and can be a common pressure sensor or a pressure strain gauge.

[0024] When the steam pressure in the steam pipeline changes, the pressure on the pressure-bearing layer 131 will also change, which will cause the pressure of the pressure-bearing liquid 134 to change, causing the pressure transmission layer 133 to deform. Since a pressure detection unit 14 is fixed between the pressure transmission layer 133 and the inner top surface of the lower valve body 11, the pressure change caused by its deformation can be detected, thereby determining the steam pressure in the steam pipeline.

[0025] As attached Figure 2 , 4 As shown, the pipeline deformation detection unit 2 includes a pipe sleeve 21, a fixing plate 22, and a pressure detection component 23. The pipe sleeve 21 includes two semicircular pipe clamps 211, which are fixed to the steam pipe to be detected. A support plate 212 perpendicular to the side of the steam pipe is arranged on the side of the pipe clamp 211, and a fixing plate 22 parallel to the support plate 212 is arranged on one side of the support plate 212. The fixing plate 22 is fixed to a firm structure outside the pipe, such as a wall or a concrete base, and a pressure detection component 23 is arranged between the support plate 212 and the fixing plate 22.

[0026] The pressure detection assembly 23 includes an axial detection unit 231 and a radial detection unit 232. The axial detection unit 231 includes two force transmission blocks 2311 arranged opposite to each other along the axial direction of the steam pipe, which are respectively fixed to the relative areas of the support plate 212 and the fixed plate 22, and an axial force sensor 2312 is arranged in the center of the two force transmission blocks 2311. The radial detection unit 232 includes two force transmission plates 2321 arranged opposite to each other in the radial direction of the steam pipe and parallel to the axial direction of the pipe, and the ends of the two force transmission plates are respectively fixed to the relative areas of the support plate 212 and the fixed plate 22, and a radial force sensor 2322 is arranged in the center of the two force transmission plates 2321. The axial and radial deformation of the steam pipe within a certain range on both sides of the pipe deformation detection unit 2 can be detected by the axial force sensor 2312 and the radial force sensor 2322.

[0027] It should be noted that, unless otherwise clearly specified and limited, the terms such as "install", "connect", "connect", "fix", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
