[0022] 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.

[0023] Example

[0024] This embodiment is intended to help solve the problem that it is inefficient to detect each component that may cause damage through an electric meter. Figure 1-5 A fault locating device for instrument equipment includes an instrument housing 1, a circuit board 2 is installed in the instrument housing 1, a temperature transfer device 3 is installed on one side of the circuit board 2, a temperature reaction device 4 is installed on the temperature transfer device 3, a mounting back plate 5 is provided on one side of the temperature reaction device 4, a power supply device 7 is also installed in the instrument housing 1, and the connection between the power supply device 7 and the circuit board 2 is restricted by the mounting back plate 5.

[0025] In this embodiment: the temperature transfer device 3 includes a positioning plate 301, one side of the positioning plate 301 is installed on the back of the circuit board 2, a heat pipe 302 is installed in the positioning plate 301, and one side of the heat pipe 302 is connected to the temperature reaction device 4. When the circuit board 2 encounters corrosion, continuing to work will cause the surrounding components to continue to heat up, and this high temperature is transferred to 4 through the positioning plate 301 and the heat pipe 302, and the power supply is quickly disconnected by the drive of the temperature reaction device 4, and the damaged component is quickly located. At the same time, the positioning plate 301 with a certain elasticity can effectively protect the welding points on the back of the circuit board 2, so that the heat dissipated by the faulty component can be introduced into the temperature reaction device 4 through the heat pipe 302.

[0026] In this embodiment: the temperature reaction device 4 includes a reaction cylinder 401, a high-pressure bottle 402 is fixedly connected inside the reaction cylinder 401, one side of the high-pressure bottle 402 is connected to the heat pipe 302, and a T-shaped piston plate 403 is slidably connected inside the reaction cylinder 401. The T-shaped piston plate 403 penetrates the reaction cylinder 401. After the component on the circuit board 2 fails and the temperature rises, the temperature is transferred to the high-pressure bottle 402 in the reaction cylinder 401 through the heat pipe 302. When the high-pressure bottle 402 is subjected to a certain temperature, it will explode and increase the air pressure of the surrounding air. Through the explosion of the No. 1 spring 502, the air pressure in the reaction cylinder 401 is increased, thereby driving the T-shaped piston plate 403 to move. Through the physical changes of the T-shaped piston plate 403, the damaged component can be quickly located after the instrument is disassembled.

[0027] In this embodiment: the mounting back plate 5 includes a mounting plate 501, which is mounted on one side of the instrument housing 1, and a No. 1 spring 502 is fixedly connected to one side of the mounting plate 501, and a sliding plate 503 is fixedly connected to the other end of the No. 1 spring 502, and the sliding plate 503 is slidably connected inside the instrument housing 1, and one side of the sliding plate 503 contacts one end of the T-type piston plate 403. When a fault occurs in the circuit board 2, the T-type piston plate 403 at the faulty component contacts the sliding plate 503, driving the sliding plate 503 to slide in the instrument housing 1, thereby compressing the No. 1 spring 502. The mounting plate 501 is mounted on one side of the instrument housing 1 by bolts, which can provide certain protection for the inside of the instrument, and the instrument can be quickly disassembled by bolt connection. The No. 1 spring 502 is used to apply a certain driving force to the sliding plate 503 during installation, driving the power supply device 7 to supply power to the circuit board 2.

[0028] In this embodiment: the fault of the circuit board 2 is indicated by the display rod 6, one end of the display rod 6 is fixedly connected to one side of the sliding plate 503, and the other end of the display rod 6 is rotatably connected to the mounting plate 501. When a fault occurs during normal use of the instrument, the sliding plate 503 is driven to slide in the instrument housing 1 through the temperature transfer device 3 and the temperature reaction device 4, and the display rod 6 in the mounting back plate 5 is pushed out at the same time. Through the physical change of the extension of the display rod 6, the user can quickly discover the abnormality of the instrument and repair the instrument as soon as possible.

[0029] In this embodiment: the power supply device 7 includes a sliding groove 701 opened in the instrument housing 1, and a battery compartment 702 is slidably connected in the sliding groove 701. The output end of the battery compartment 702 is connected to the power supply sensor sheet 703 of the circuit board 2. The sliding groove 701 is used to install the battery compartment 702. The sliding design of the battery compartment 702 can be replaced when the battery in the battery compartment 702 is out of power. This design of replaceable batteries makes the instrument have a longer service life. Under the resistance of the sliding plate 503, the output end of the battery compartment 702 is driven to connect with the power supply sensor sheet 703 of the circuit board 2, so that the circuit board 2 can be powered when the instrument is installed.

[0030] In this embodiment: the output end of the battery compartment 702 is fixedly connected with a No. 2 spring 8, and the other end of the battery compartment 702 is resisted by the sliding plate 503. The design of the No. 2 spring 8 allows the installation back plate 5 to be removed, or the circuit board 2 is corroded, driving the temperature transfer device 3 and the temperature reaction device 4 to slide the sliding plate 503 in the instrument housing 1, and quickly disconnecting the electrically connected battery compartment 702 from the power supply sensor sheet 703, so that the circuit board 2 is no longer powered, thereby preventing the circuit board 2 from being further damaged due to excessive temperature.

[0031] In this embodiment, a liquid crystal display screen 9 is fixedly connected to the instrument housing 1. The design of the liquid crystal display screen 9 can display the data collected and obtained by the instrument in real time, so that the user can quickly understand the specific parameters required.

[0032] Working principle: When a fault occurs in the circuit board 2, a certain high temperature will appear in the faulty component, and the temperature will be transferred to the high-pressure bottle 402 in the reaction cylinder 401 through the positioning plate 301 and the heat pipe 302, causing the high-pressure bottle 402 to explode and release the internal pressure, thereby increasing the air pressure in the reaction cylinder 401, and then driving the T-shaped piston plate 403 to slide in the reaction cylinder 401 and resist the sliding plate 503, driving the sliding plate 503 to slide in the instrument housing 1, and pushing out one end of the display rod 6 located in the mounting plate 501. At the same time, the sliding plate 503 releases the restriction on the battery compartment 702. At this time, the battery compartment 702 pops out of the sliding groove 701 under the action of the No. 2 spring 8, releasing the electrical connection between the battery compartment 702 and the power supply sensor sheet 703, causing the circuit board 2 to lose power.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
