Description

Technical Field

[0001] This application relates to the technical field of fiber optic temperature measurement devices, and in particular to a distributed fiber optic temperature measurement host. Background Technology

[0002] Distributed fiber optic temperature measurement devices are mainly used for long-distance online temperature monitoring and are also widely used in mines. Because the components in the distributed fiber optic temperature measurement device module generate heat when working, they are prone to explosion in the mine environment. Therefore, existing mine-use fiber optic temperature measurement hosts use fans for heat dissipation.

[0003] However, traditional heat dissipation designs rely on fans, which are prone to dust accumulation or explosion risks. Therefore, there is an urgent need to design a new type of distributed fiber optic temperature measurement host. Utility Model Content

[0004] To address the aforementioned issues, this application provides a distributed fiber optic temperature measurement host.

[0005] The distributed fiber optic temperature measurement host provided in this application adopts the following technical solution:

The end of the heat pipe away from the heat dissipation plate is connected to the temperature measurement host body. The temperature measurement host body is provided with a signal processing cavity, a power supply cavity and a fiber optic interface cavity.

[0007] Preferably, one end of the heat pipe is connected to the signal processing cavity, power supply cavity, and optical fiber interface cavity through the outer shell of the temperature measuring host body, and the other end is connected to the heat sink.

[0008] By adopting the above technical solution and setting up a heat dissipation base, the heat generated by the module components in the temperature measuring host is transferred to the heat dissipation plate through heat pipes, and then dissipated to the outside through the heat dissipation fins on the heat dissipation plate. This design avoids local overheating inside the host and also avoids the risk of explosion caused by traditional fan cooling.

[0009] Preferably, the heat dissipation base and the temperature measuring host body are connected by a spring clip. A connector is provided on the side of the heat dissipation plate extending outward. The connector is cylindrical and a U-shaped spring sheet is welded on the connector. Semi-cylindrical protrusions are provided on the outer sides of the two arms of the U-shaped spring sheet. The temperature measuring host body is provided with a slot corresponding to the U-shaped spring sheet. A semi-cylindrical concave part is provided at the bottom of the slot.

[0010] By adopting the above technical solution, the heat dissipation base is designed as a detachable device, which makes disassembly convenient when the heat dissipation base needs to be maintained.

[0011] Preferably, a thermally conductive insulating plate is provided between the signal processing cavity, the power supply cavity, and the optical fiber interface cavity.

[0012] By adopting the above technical solution and using a modular, compartmentalized layout design, heat accumulation and signal interference can be prevented.

[0013] Preferably, the temperature measuring host body has an optical fiber interface on its side, and the optical fiber interface is connected to the optical fiber interface cavity.

[0014] Preferably, a sealing plug is provided at the optical fiber interface.

[0015] By adopting the above technical solution and setting a sealing plug at the fiber optic interface, the temperature measuring host can be kept in a sealed state, preventing dust from entering.

[0016] Preferably, the temperature measuring host body is provided with feet at the four corners of the bottom, and the feet are connected to the temperature measuring host body by welding.

[0017] By adopting the above technical solution, the temperature measuring host can be stably placed in the mine by setting up a tripod.

[0018] Preferably, the temperature measuring host body further includes a closed door and a rotating shaft disposed on the side of the temperature measuring host body. The closed door is connected to the temperature measuring host body through the rotating shaft. The closed door is provided with bolts, and the temperature measuring host body and the closed door are provided with openings at the closing point.

[0019] By adopting the above technical solution, and through the setting of the rotating shaft and bolts, on the one hand, when it is necessary to maintain the temperature measuring host, only the closed door needs to be opened for maintenance; on the other hand, the setting of bolts keeps the inside of the temperature measuring host in a closed state, blocking external dust.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. By setting up the temperature measuring host body and heat dissipation base, the heat generated by the module components in the temperature measuring host is transferred to the heat dissipation plate through heat pipes, and then dissipated to the outside through the heat dissipation fins on the heat dissipation plate. This design avoids local overheating inside the host and also avoids the risk of explosion caused by traditional fan cooling.

[0022] 2. The modular, compartmentalized design prevents heat buildup and signal interference, and is easier to maintain compared to integrated modules. Attached Figure Description
