Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The embodiment of the utility model discloses temperature measurement optical cable installing support for reactor. The temperature measurement optical cable mounting bracket has a good temperature resistance function and can resist the high temperature of 150 ℃. As shown in fig. 1 to 5, the temperature measuring cable mounting bracket includes: the device comprises an elastic support frame 2 used for abutting against the inner wall of an air duct 1 of the reactor, an elastic piece 3, two symmetrically arranged fixing frames 4 and a pressing plate 5. One end of the elastic part 3 is connected with the elastic supporting frame 2, and the other end of the elastic part 3 is connected with the two fixing frames 4. A gap 6 for embedding the optical cable 7 is arranged between the two fixing frames 4, namely the gap 7 is used as a mounting groove for the optical cable 6. The elastic member 3 may be a wave-shaped elastic member which is stretchable in the axial direction. The pressing plate 5 is detachably mounted on the surfaces of the two fixing frames 4 facing away from the elastic member 3 across the gap 6 between the two fixing frames 4, so that the optical cable 7 can be prevented from falling off by covering at least part of the gap with the pressing plate 5 after the optical cable 7 is inserted into the gap 6. The holder 4 and the pressure plate 5 may be made of plastic.
In a preferred embodiment, the temperature measuring cable mounting bracket of the embodiment of the present invention may further have the following structure: the two opposite sides of the surfaces of the two fixing frames 4 facing the elastic element 3 are provided with clamping grooves. The two ends of the pressure plate 5 are provided with hooks. The pressing plate 5 is detachably arranged on the surfaces of the two fixing frames 4 which are opposite to the elastic piece 3 by embedding each hook into each corresponding clamping groove,
preferably, the end surface of the other end of the elastic member 3 has a curvature. The radian should meet the requirement of the bending degree of the optical fiber 7, so that the optical fiber 7 can be protected and the optical fiber 7 is prevented from being damaged due to over bending.
The elastic support frame 2 is an internal support type support frame. In a preferred embodiment, the temperature measuring cable mounting bracket of the embodiment of the present invention may further have the following structure: the elastic support frame 2 includes: two elastic supporting legs which are symmetrically arranged, and one ends of the two elastic supporting legs are connected with the elastic part 3. The other ends of the two elastic legs are used for abutting against the inner wall of the air duct 1 of the reactor. Under the unstressed state, the distance between one ends of the two elastic supporting legs is smaller than the distance between the other ends of the two elastic supporting legs. Because two elastic support legs have elasticity, consequently, the other end of two elastic support legs can be close to each other or keep away from under the exogenic action to adapt to the not unidimensional wind channel 1 of reactor, can stabilize the card in wind channel 1. Preferably, the end face of the other end of each elastic supporting leg is provided with textures, so that friction can be increased, and the elastic supporting frame 2 can be firmly clamped with the side wall of the air duct 1 of the reactor.
When the temperature measuring electric reactor is used, two temperature measuring optical cable mounting brackets are matched in one air channel 1 of the electric reactor. One temperature measuring optical cable mounting bracket is arranged at one end of the air duct 1, and the other temperature measuring optical cable mounting bracket is arranged at the other end of the air duct 1. The reactor generally has a plurality of wind channels 1, and temperature measurement optical cable installing supports can be uniformly arranged in the plurality of wind channels 1 at intervals so as to install the optical cables 7. For each temperature measuring optical cable mounting bracket, the elastic support frame 2 is supported on the inner wall of the end of the air duct 1 in an abutting mode, and the elastic part 3 is just erected on the end face of the end of the air duct 1. One end of the optical cable 7 can extend and be embedded into a gap 6 between two fixing frames 4 of the temperature measuring optical cable mounting bracket at one end of the air duct 1, and then a pressing plate 5 of the temperature measuring optical cable mounting bracket is mounted. One end of the optical cable 7 extends to the other end of the air duct 1 along the air duct 1, then extends and is embedded into a gap 6 between two fixing frames 4 of the temperature measurement optical cable mounting bracket at the other end of the air duct 1, then a pressing plate 5 of the temperature measurement optical cable mounting bracket is mounted, then one end of the optical cable 7 extends towards the next air duct 1, and the like. The temperature measurement optical cable mounting bracket is matched with each other for limiting, so that the optical cable 7 is tightly attached to the winding conductor when extending. For the optical cable 7 in the same air duct 1, when the optical cable 7 contracts or expands due to reasons such as environmental temperature, the elastic parts 3 of the two optical cable mounting brackets can be adjusted in a telescopic mode under the elastic action, so that the optical cable 7 can contract or expand, and the problem that the optical cable 7 is damaged due to the fact that the two temperature measuring optical cable mounting brackets do not deform when the optical cable 7 contracts or expands (particularly contracts) is solved.
To sum up, the utility model discloses a temperature measurement optical cable installing support for reactor can distribute the deployment on the reactor surface, guarantees that temperature measurement optical cable and reactor conductor reliably lay and laminate to realize that the optical cable is more effective, accurately monitor the reactor temperature in different positions.
