Description

Technical Field

[0001] The present invention relates to the field of fire alarms, and in particular to an oil tank floating roof fire temperature early warning device and an installation method. Background Art

[0002] With the development of society, the use of petroleum products in various places has increased, resulting in great hidden dangers in the production and storage of petroleum. Petroleum tank areas mainly store oil products and are built in open-air environments. Once a flammable liquid storage container leaks, flammable liquid vapor will appear. Even if it comes into contact with a tiny spark, it will cause combustion. In order to avoid irreversible consequences, a tank floating roof fire temperature warning module is designed. The module is installed at the secondary seal of the tank floating roof, and it moves up and down with the floating roof to detect the air temperature near the secondary seal to achieve fire warning. If the module is not installed firmly, the information it transmits will be prolonged and unstable. Therefore, the development and design of a fixed frame and usage method that saves costs, increases the service life of the module, is easy to install, and is firm and stable is an effective way to meet the needs of tank floating roof fire temperature warning modules. Summary of the Invention

[0003] In order to increase the service life and save hardware costs, the purpose of the present invention is to provide a fixing device to stabilize the oil tank floating roof fire temperature warning module and increase its service life.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A temperature warning device for a fire on a floating roof of an oil tank is provided. A floating roof is provided directly above the oil tank, comprising a temperature warning module and a temperature warning module bracket. The inner side of the floating roof is connected to a floating roof ring by screws. The temperature warning module bracket is fixed above the floating roof ring by screws. A temperature warning module is provided inside the temperature warning module bracket. A temperature sensing probe of the temperature warning module faces the direction of a secondary seal between the inner wall of the oil tank and the floating roof, and is fixed upward at a right angle in a direction opposite to the secondary seal between the inner wall of the oil tank and the floating roof. The temperature warning module moves up and down with the floating roof to detect the air temperature near the secondary seal to achieve early warning.

[0006] Furthermore, the temperature warning module includes a rectangular housing and a circuit board. The circuit board is fixed inside the housing by screws. The circuit board is sequentially provided with an AD module, a single-chip microcomputer, and a wireless module. A battery is provided at the bottom of the circuit board. A temperature sensor is provided on one side of the circuit board, and a module antenna is provided on the side opposite to the temperature sensor. Furthermore, the temperature warning module bracket includes an upper cover and a lower cover.

[0007] The four sides of the upper cover are respectively provided with a first cover folding edge, a second cover folding edge, a third cover folding edge and a fourth cover folding edge, and the fourth cover folding edge is provided with two threaded holes;

[0008] The four sides of the lower cover are respectively provided with a first folded edge, a second folded edge, a third folded edge and a fourth folded edge, and the fourth folded edge is provided with two threaded holes; a support plate is provided directly below the lower cover, and a fixed base is provided below the support plate, and a threaded hole is provided on the fixed base; the four corners of the upper end of the lower cover are respectively provided with a first support column, a second support column, a third support column and a fourth support column; a drainage hole is provided at the bottom of the lower cover.

[0009] A method for installing a temperature warning device for a fire on an oil tank floating roof:

[0011] S2: Place the upper cover on the temperature warning module so that it is combined with the lower cover to prevent the temperature warning module from being overheated due to sun exposure, thereby affecting the accuracy of the data.

[0012] S3: Use screws to pass through the threaded holes in the fourth cover fold on the upper cover and the threaded holes in the fourth fold on the lower cover. Screw the temperature warning module to the second cover fold on the upper cover and the second fold on the lower cover to secure the temperature warning module. This prevents slow and inaccurate data transmission due to unstable fixation of the temperature warning module.

[0013] S4: Use screws to pass through the fixing base with fixing holes to evenly fix the entire temperature warning module bracket on the floating roof ring.

[0014] The present invention has the following beneficial effects:

[0015] 1. This invention utilizes a floating roof ring, a temperature preload module bracket, and a temperature preload module within the temperature preload module bracket. The temperature preload module moves up and down with the floating roof, detecting the air temperature near the secondary seal to provide early warning. This design is simple, easy to install, and low-cost.

[0016] 2. The temperature warning module of the present invention includes a rectangular shell and a circuit board. The circuit board is fixed inside the shell by screws.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown: On an oil tank with a floating roof, each temperature warning module bracket 28 with a temperature warning module 1 is evenly fixed on the floating roof ring 27 by screws. The temperature sensing probe 22 of the temperature warning module 1 must face the secondary seal 25 between the oil tank inner wall 26 and the floating roof 20. The module antenna 19 of the temperature warning module 1 must be fixed upward at a right angle in the opposite direction to the secondary seal 25 between the oil tank inner wall 26 and the floating roof 20. The temperature warning module 1 will move up and down with the floating roof 20 to detect the air temperature near the secondary seal 25 to achieve fire warning.

[0028] like Figure 7 As shown, the temperature warning module 1 includes a rectangular housing 23 and a circuit board 21. The circuit board 21 is fixed to the interior of the housing 23 with screws. The circuit board 21 is sequentially equipped with an AD module, a single-chip microcomputer, and a wireless module. A battery is located at the bottom of the circuit board 21. A temperature sensor 22 is located on one side of the circuit board 21, and a module antenna 19 is located on the side opposite the temperature sensor 22. The temperature sensor 22 of the temperature warning module 1 detects the temperature near the secondary seal 25. After processing by the AD module and the single-chip microcomputer, the data is transmitted to the terminal via the wireless module to provide an early warning.

[0029] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown: the top of the temperature warning module bracket 28 is the upper cover plate 2, and a nameplate 3 is engraved on the upper cover plate 2. The first cover plate folding edge 4, the second cover plate folding edge 5, the third cover plate folding edge 6, and the fourth cover plate folding edge 7 are respectively installed around the upper cover plate 2, and the fourth cover plate folding edge 7 has two threaded holes. The lower cover plate 10 is installed below the temperature warning module 1, and the bottom of the lower cover plate 10 is provided with a drainage hole 29. The first folding edge 11, the second folding edge 12, the third folding edge 13, and the fourth folding edge 14 are installed around the lower cover plate 10, and the fourth folding edge 14 has two threaded holes. The support plate 8 is installed directly below the fixing frame 10, and the fixed base 9 is installed below the support plate 8. The fixed base 9 has a threaded hole, and the first support column 15, the second support column 16, the third support column 17, and the fourth support column 18 are respectively installed at the four corners of the lower cover plate 10.

[0030] like Figure 2 As shown, a method for installing an oil tank floating roof fire temperature warning device includes the following steps:

[0031] S1: Place the oil tank floating roof fire temperature warning module 1 above the four support columns 8 on the lower cover 10, leaving a gap between the module and the bottom of the lower cover 10 to facilitate drainage through the drainage holes 29 at the bottom of the lower cover 10 and prevent water accumulation that may cause rust on the housing of the temperature warning module 1;

[0032] S2: Cover the upper cover 2 on the temperature warning module 1 so that it is combined with the lower cover 10 to prevent the temperature warning module 1 from being exposed to the sun and causing the temperature to be too high, thereby affecting the accuracy of the data;

[0033] S3: Use screws to pass through the threaded holes of the fourth cover fold 7 on the upper cover 2 and the threaded holes of the fourth fold 14 on the lower cover 10. Use the screws to push the temperature warning module 1 to the second cover fold 5 on the upper cover 2 and the second fold 12 on the lower cover 10 to fix the temperature warning module 1 (the fixing here does not mean pushing the screws hard to fix the temperature warning module 1, but rather gently touching the temperature warning module 1 to the second fold to fix it in this position). This prevents the temperature warning module 1 from being unstable and causing slow and inaccurate data transmission;

[0034] S4: Use screws to pass through the fixed base 9 with fixing holes to evenly fix the entire temperature warning module bracket 28 on the floating roof ring 27. The temperature sensing probe 22 of the temperature warning module 1 must face the direction of the secondary seal 25 between the inner wall 26 of the oil tank and the floating roof 20. The module antenna 19 of the temperature warning module 1 must be fixed upward at a right angle in the opposite direction of the secondary seal 25 between the inner wall 26 of the oil tank and the floating roof 20. The temperature warning module 1 will move up and down with the floating roof 20 to detect the air temperature near the secondary seal 25 to implement early warning.
