[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0035] Please see Figures 1-6The present invention provides a temperature rise over-limit early warning device, which includes: a connecting mechanism 1, a detection mechanism 2 adapted to the connecting mechanism 1, and an alarm mechanism 3 connected to the connecting mechanism 1.

[0036] In some embodiments, the connecting mechanism 1 is used to connect the temperature rise over-limit early warning device to the device under test, including: a connecting plate 11, a connecting frame 12 disposed on the connecting plate 11, and a connecting wheel 13 disposed on the connecting frame 12. In some embodiments, the connecting plate 11 has an arc-shaped structure. By designing the connecting plate 11 as an arc-shaped structure, the connecting plate 11 can wrap around the device under test, thereby connecting the connecting mechanism 1 to the device under test. For example, when the device under test is an object such as a pipe, the connecting mechanism 1 can continuously perform temperature rise detection following the direction of the pipe.

[0037] In some embodiments, the connecting frame 12 is disposed on the connecting plate 11 and is used to adjust the angle of the connecting wheel 13. The connecting frame 12 includes a first swing arm 121, a second swing arm 122 connected to the first swing arm 121, and a first power component 123 connected to the first swing arm 121. The first power component 123 is a part used to generate power and transmit it to subsequent components or actuators. The first power component 123 may be a motor, which may convert electrical energy into mechanical energy based on the principle of electromagnetic induction.

[0038] Furthermore, the first power assembly 123 is connected to the first swing arm 121. In some embodiments, one end of the first swing arm 121 is connected to one end of the second swing arm 122, and the other end is connected to the connecting wheel 13. The connecting ends of the first swing arm 121 and the second swing arm 122 mesh with each other and are both gear structures with grooves. The above design causes the second swing arm 122 to rotate along with the first swing arm 121 when the first power assembly 123 drives the first swing arm 121 to rotate. The rotation direction of the second swing arm 122 is opposite to the rotation direction of the first swing arm 121, so that the first swing arm 121 and the second swing arm 122 move closer or further away from each other, thereby causing the connecting wheel 13 connected to the connecting frame 12 to come into contact with or separate from the device being tested.

[0039] In some embodiments, the connecting wheel 13 is arranged perpendicular to the connecting frame 12, such that the wheel surface of the connecting wheel 13 can abut against the device being tested.

[0040] In some embodiments, the detection mechanism 2 is used to acquire the temperature of the device under test, and includes: an electric push rod 21, a fixed frame 22 disposed on the electric push rod 21, and a temperature sensor 23 disposed on the fixed frame 22. In some embodiments, the electric push rod 21 is a device that converts electrical energy into linear mechanical motion, thereby using the electric push rod 21 to drive the fixed frame 22 to move, so that the temperature sensor 23 fixed on the fixed frame 22 comes into contact with the device under test, thereby acquiring the temperature of the device under test. An exemplary temperature sensor 23 is a thermistor, which uses the change in resistance value with temperature to acquire the temperature of the device under test.

[0041] In some embodiments, the alarm mechanism 3 is used to issue an alarm message when the temperature rise of the tested equipment exceeds the limit. It includes a controller 31, and a buzzer 32 and an alarm light 33 connected to the controller 31. In some embodiments, the controller 31 is communicatively connected to the temperature sensor 23 and is used to issue an alarm command to the buzzer 32 and the alarm light 33 when the temperature rise exceeds the limit. For example, the controller 31 stores a temperature threshold. The controller 31 compares the temperature obtained by the temperature sensor 23 with the temperature threshold. When the temperature obtained by the temperature sensor 23 exceeds the temperature threshold, it issues an alarm command to the buzzer 32 and the alarm light 33. The buzzer 32 emits an alarm sound, and the alarm light 33 emits an alarm light to alert the operator.

[0042] In some more preferred embodiments, the temperature rise over-limit early warning device further includes: a transmission mechanism 4 connected to the detection mechanism 2 and adapted to the connecting mechanism 1. The transmission mechanism 4 is used to drive the detection mechanism 2 to rotate along the tested equipment with the connecting mechanism 1 as the fulcrum, thereby obtaining the multi-point temperature of the tested equipment. It includes: a second power component 41, a first transmission gear 42 connected to the second power component 41, a second transmission gear 43 and a third transmission gear 44 connected to the first transmission gear 42, a transmission shaft 45 connected to the second transmission gear 43 and the third transmission gear 44, a fourth transmission gear 46 disposed on the transmission shaft 45, and a rack 47 connected to the fourth transmission gear 46. The second power component 41 is the part used to generate power and transmit it to subsequent components or actuators. The second power component 41 can be a motor, which can convert electrical energy into mechanical energy based on the principle of electromagnetic induction.

[0043] Furthermore, the output end of the second power component 41 is connected to the first transmission gear 42. The second transmission gear 43 and the third transmission gear 44 are located on both sides of the first transmission gear 42. Under the transmission action of the first transmission gear 42, the second transmission gear 43 and the third transmission gear 44 can rotate in the same direction, thereby driving the transmission shaft 45 connected to the second transmission gear 43 and the third transmission gear 44 to rotate in the same direction.

[0044] Furthermore, the rack 47 is disposed on the outer periphery of the connecting plate 11. After the connecting plate 11 is connected to the device under test, the force of the rotation of the fourth transmission gear 46 on the rack 47 is used to drive the detection mechanism 2 to rotate along the device under test through the transmission mechanism 4, thereby realizing multi-point detection of the device under test and improving the technical effect of fire early warning. In some more preferred embodiments, the device under test may also be provided with a fixing groove adapted to the connecting wheel 13. On the one hand, this allows the connecting mechanism 1 to move in a predetermined direction, and on the other hand, it can also be conveniently matched with the connecting wheel 13 to form a fulcrum for the transmission detection mechanism 2 to rotate along the device under test.

[0045] In some embodiments, the transmission mechanism 4 further includes: a fixed base 48 and a limiting roller 49 connected to the fixed base 48. The fixed base 48 is used to fix and support components such as the second power assembly 41, the first transmission gear 42, the second transmission gear 43, the third transmission gear 44, and the transmission shaft 45. On the other hand, it cooperates with the limiting roller 49 to limit the rotation direction of the transmission mechanism 4. Specifically, the fixed base 48 has a structure with high sides and a hollow middle. The two ends of the limiting roller 49 are rotatably connected to the high points on both sides of the fixed base 48. The connecting disk 11 passes through the hollow space formed by the fixed base 48 and the limiting roller 49 and is connected to the fixed base 48.

[0046] Furthermore, the limiting roller 49 is connected to the inner wall of the connecting disk 11, and the rack 47 is disposed on the outer wall of the connecting disk 11. The above structure allows the transmission mechanism 4 to only move along the setting direction of the rack 47 on the connecting disk 11 when the transmission mechanism 4 is flipped. The limiting roller 49 assists the transmission mechanism 4 in moving on one hand, and can also connect the transmission mechanism 4 to the connecting mechanism 1 on the other hand.

[0047] In some more preferred embodiments, the temperature rise over-limit early warning device further includes: an adjustment mechanism 5 connected to the transmission mechanism 4, the adjustment mechanism 5 being used to adjust the distance between the connecting mechanism 1 and the detection mechanism 2 to adapt to the device being detected, and includes: a threaded block 51, a threaded rod 52 adapted to the threaded block 51, a third power component 53 connected to the threaded rod 52, and a guide rod 54 slidably connected to the threaded block 51, wherein the threaded block 51 is connected to the fixed seat 48 and threadedly connected to the threaded rod 52, cooperating to convert rotational motion into linear motion, the third power component 53 is connected to one end of the threaded rod 52, wherein the third power component 53 is the part used to generate power and transmit it to subsequent components or actuators, the third power component 53 may be a motor, the motor may be based on the principle of electromagnetic induction to convert electrical energy into mechanical energy. The threaded rod 52 is used to rotate and drive the threaded block 51, as well as the transmission mechanism 4 and the connecting mechanism 1 connected to the threaded block 51, to achieve displacement. The guide rod 54 is slidably connected to the threaded block 51 to enhance the smoothness of the movement of the threaded block 51, thereby adjusting the distance between the connecting mechanism 1 and the detection mechanism 2 and enhancing practicality.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
