The coal conveying program control system and the dumper interlocking protection program are further developed, and the working condition and the automation performance of the dumper are improved through the arrangement of the communication optical fiber.

[0039] Further, by arranging the connecting unit 200, the corresponding component for fixing and installing the optical cable unit 100 is arranged on the optical cable insulation layer by arranging the mounting seat 201 on the optical cable insulation layer 101. The position between the mounting seat 201 on the optical cable insulation layer 101 and the laying pipeline unit 400 to be installed is adjusted by arranging the adjusting part 202 on the mounting seat 201, then the optical cable insulation layer 101 and the laying pipeline unit 400 are fixed by arranging the mounting part 203 on the adjusting part 202 and connecting the laying pipeline unit 400 of the optical cable unit 100, and finally the mounting part 203 is tightened by arranging the tightening part 204 on the mounting part 203, so that the optical cable unit 100 and the laying pipeline unit 400 are stably connected.

[0040] In use, when the staff lays the optical cable unit 100 inside the working environment, the connecting unit 200 arranged at both ends of the optical cable unit 100 is used to install the optical cable unit 100, and the specific process is as follows: first, the position of the mounting seat 201 is calibrated at the installation port of the laying pipeline unit 400. The position of the mounting portion 203 relative to the installation point is adjusted by the adjusting portion 202. After the mounting portion 203 is fixedly arranged at the installation point of the laying pipeline unit 400, the position of the mounting portion 203 is fixedly adjusted by the tightening portion 204, so that the mounting portion 203 and the adjusting portion 202 arranged on the mounting seat 201 are stably arranged on the laying pipeline unit 400, thereby completing the stable arrangement of the optical cable unit 100 in the laying pipeline unit 400, improving the laying efficiency of the staff, and facilitating the later maintenance and repair.

[0041] Embodiment 2, refer to Figures 1-5 For the second embodiment of the present application, the difference between this embodiment and the first embodiment is that the adjusting portion 202 comprises an adjusting rod one 202a rotatably arranged on the mounting seat 201, and an adjusting rod two 202b rotatably connected at one end to the adjusting rod one 202a and rotatably connected at the other end to the mounting portion 203; wherein the adjusting rod one 202a or the adjusting rod two 202b is provided with a tightening sleeve one 202c.

[0042] In use, when the staff lays the optical cable unit 100 inside the working environment, the connecting unit 200 arranged at both ends of the optical cable unit 100 is used to install the optical cable unit 100, and the specific process is as follows: first, the position of the mounting seat 201 is calibrated at the installation port of the laying pipeline unit 400. The position of the mounting portion 203 relative to the installation point is adjusted by the adjusting portion 202, wherein the relative position of the mounting plate 203a on the adjusting rod two 202b relative to the laying pipeline unit 400 is adjusted by the rotatable connection between the adjusting rod one 202a and the adjusting rod two 202b. The requirement of quickly installing the optical cable unit 100 on laying pipeline units 400 of different specifications and sizes is achieved. Then, after the mounting portion 203 is fixedly arranged at the installation point of the laying pipeline unit 400, the position of the mounting portion 203 is fixedly adjusted by the tightening portion 204, so that the mounting portion 203 and the adjusting portion 202 arranged on the mounting seat 201 are stably arranged on the laying pipeline unit 400, thereby completing the stable arrangement of the optical cable unit 100 in the laying pipeline unit 400, improving the laying efficiency of the staff, and facilitating the later maintenance and repair.

[0043] Further, compared with the embodiment 1, the mounting portion 203 comprises a mounting plate 203a rotationally connected with the adjusting rod two 202b, and a tightening sleeve two 203b arranged on the mounting plate 203a; wherein the mounting plate 203a is provided with a rotation slot 203a-1 rotationally connected with the adjusting rod two 202b, and the mounting plate 203a is provided with an arc surface A corresponding to the laying pipe unit 400 of the optical cable unit 100. By arranging the arc surface A corresponding to the laying pipe unit 400 of the optical cable unit 100 on the mounting plate 203a, the mounting stability of the mounting plate 203a relative to the laying pipe unit 400 is improved, which is conducive to improving the installation stability of the optical cable unit 100 on the laying pipe unit 400, and further improving the anti-physical interference capability of the optical cable unit 100.

[0044] Further, the tightening portion 204 comprises an adjusting portion tightening member 204b arranged on the tightening sleeve one 202c, the adjusting portion tightening member 204b comprising a tightening rope one 204b-1 arranged on the tightening sleeve one 202c, and a tightening ring one 204b-2 arranged on the tightening rope one 204b-1; the tightening portion 204 further comprises a mounting portion tightening member 204c arranged on the tightening sleeve two 203b, the mounting portion tightening member 204c comprising a tightening rope two 204c-1 arranged on the tightening sleeve two 203b, and a tightening ring two 204c-2 arranged on the tightening rope two 204c-1. Wherein the tightening rope one 204b-1 is arranged on the tightening sleeve one 202c, and the staff tightens the tightening sleeve one 202c arranged on the adjusting rod one 202a or the adjusting rod two 202b by using the tightening ring one 204b-2, so as to improve the stability of the adjusting portion 202. Similarly, the tightening rope two 204c-1 is arranged on the tightening sleeve two 203b, and the staff tightens the tightening sleeve two 203b arranged on the mounting plate 203a by using the tightening ring two 204c-2, so as to improve the stability of the mounting plate 203a on the laying pipe unit 400.

[0045] Preferably, the mounting seat 201 is uniformly distributed at both ends of the optical cable insulation layer 101 with the optical fiber 102 as the center. Thus, it is convenient to arrange the optical cable unit 100 on the cylindrical laying pipe unit 400, which is conducive to improving the connection stability of the mounting portion 203 and the adjusting portion 202 on the mounting seat 201 relative to the laying pipe unit 400, and also convenient for connecting and installing the laying pipe unit 400 with different diameters.

[0046] The remaining structure is the same as that of the embodiment 1.

[0047] Embodiment 3, refer to Figures 6-9For the third embodiment of the present application, the second embodiment is proposed, which comprises an optical-electric conversion system, comprising the optical cable convenient to lay and the optical-electric conversion unit 300. The optical-electric conversion unit 300 comprises the alarm assembly 301 arranged on the connecting unit 200, the optical fiber mounting assembly 302 arranged on the alarm assembly 301, and the optical-electric conversion assembly 303 arranged on the optical fiber mounting assembly 302. By arranging the optical-electric conversion assembly 303, the working equipment protection program proposed in the first embodiment is increased with the optical-electric conversion module, the interference of electromagnetic waves generated by system operation on the detection signal is reduced, the automation level of the mechanical equipment similar to the dumper system is improved, the dumper unloading process is optimized, and the working safety of the equipment is protected. At the same time, the problems of poor anti-interference ability of the traditional optical cable signal transmission, inconvenient installation, and single signal transmission function are solved. The technical effect of laying a single optical cable in a small space with a complex working environment to complete a variety of complex signal transmission work is achieved.

[0048] Further, the alarm assembly 301 comprises the temperature sensing shell part 301a arranged on the connecting unit 200, the alarm seat 301b arranged in the temperature sensing shell part 301a, the refracting part 301c arranged on the alarm seat 301b, and the fusible shielding part 301d arranged on the refracting part 301c and located between the optical-electric conversion assembly 303 and the refracting part 301c.

[0049] In the use process, by arranging the alarm assembly 301, the temperature of the working environment where the optical cable unit 100 is located can be monitored by the temperature sensing shell part 301a. When the temperature of the temperature sensing shell part 301a exceeds the normal value of the working temperature of the optical cable unit 100, a fusible metal ball with a melting point close to the normal working temperature of the optical cable unit 100 is arranged in the temperature sensing shell part 301a. After the temperature is too high, the metal ball melts, the signal transmitting optical fiber located on the optical fiber mounting assembly 302 can realize signal refraction transmission through the refracting part 301c, and the signal receiving optical fiber can realize signal reception through the refracting part 301c, so that the high-temperature abnormal signal is sent to the corresponding alarm equipment along the signal receiving optical fiber, thereby facilitating rapid alarm of the abnormal temperature of the optical cable unit 100, avoiding damage to the working efficiency of the control system and the strength of the communication signal caused by the high temperature of the environment or the high temperature of the optical cable itself. When the environmental temperature is normal or the temperature of the optical cable itself is also within the normal working range, the surface of the metal ball of the fusible shielding part 301d is coated with a light shielding coating, the signals between the signal receiving optical fiber and the signal transmitting optical fiber are shielded and cannot be received by each other, so no high-temperature alarm will be performed.

[0050] Preferably, the temperature sensing shell part 301a comprises a shell body 301a-1, a sliding seat one 301a-2 and a sliding seat two 301a-3 slidingly arranged on the shell body 301a-1, a refracting part 301c arranged on the sliding seat one 301a-2, and a fusible shielding part 301d arranged on the sliding seat two 301a-3. The sliding seat one 301a-2 and the sliding seat two 301a-3 are slidingly arranged on the shell body 301a-1, and the shell body 301a-1 is provided with an expansion blade 301a-4, which protects the refracting part 301c and the fusible shielding part 301d inside the shell body 301a-1.

[0051] Further, the refracting part 301c comprises a refracting ball mounting seat 301c-1 arranged on the alarm seat 301b, and a refracting ball 301c-2 arranged on the refracting ball mounting seat 301c-1; the fusible shielding part 301d comprises a fusible metal ball mounting seat 301d-1 arranged on the alarm seat 301b, a fusible metal ball 301d-2 arranged on the fusible metal ball mounting seat 301d-1, and a pollution prevention tray 301d-3 arranged on the fusible metal ball mounting seat 301d-1 and located between the fusible metal ball 301d-2 and the photoelectric conversion assembly 303. The pollution prevention tray 301d-3 is arranged to avoid the fusible metal ball 301d-2 from affecting the normal work of the photoelectric conversion assembly 303 on the fiber mounting seat 302 after melting.

[0052] Further, the fiber mounting assembly 302 comprises an adjusting sleeve 302a arranged on the temperature sensing shell part 301a, a fiber mounting seat 302c slidingly arranged on the adjusting sleeve 302a, and a rotating knob 302b rotationally connected with the adjusting sleeve 302a and threadedly connected with the fiber mounting seat 302c. The rotating knob 302b is arranged to adjust the position of the fiber mounting seat 302c relative to the adjusting sleeve 302a, so as to adjust the distance between the photoelectric conversion assembly 303 arranged on the fiber mounting seat 302c and the alarm module inside the temperature sensing shell part 301a.

[0053] Further, the photoelectric conversion assembly 303 comprises a signal transmitting optical fiber 303a arranged on the fiber mounting seat 302c, a signal receiving optical fiber 303b arranged on the fiber mounting seat 302c, a signal transmitting seat 303c arranged on the signal transmitting optical fiber 303a and facing the alarm assembly 301, and a signal receiving seat 303d arranged on the signal receiving optical fiber 303b and facing the alarm assembly 301.

[0054] In use, the signal emitting seat 303c on the signal emitting optical fiber 303a emits a signal, and the corresponding signal receiving seat 303d on the signal receiving optical fiber 303b receives the signal. Thus, through the alarm assembly 301, the temperature sensing shell part 301a is arranged to monitor the temperature of the working environment of the optical cable unit 100. When the temperature of the temperature sensing shell part 301a exceeds the normal value of the working temperature of the optical cable unit 100, a fusible metal ball with a melting point close to the normal working temperature of the optical cable unit 100 is arranged in the temperature sensing shell part 301a. When the temperature is too high, the metal ball melts, the signal emitting optical fiber on the optical fiber mounting assembly 302 can realize signal refraction transmission through the refraction part 301c, and the signal receiving optical fiber can realize signal receiving through the refraction part 301c, so as to send the high-temperature abnormal signal along the signal receiving optical fiber to the corresponding alarm device, thereby facilitating rapid alarm of the abnormal temperature of the optical cable unit 100, and avoiding damage to the working efficiency of the control system and the strength of the communication signal caused by the high temperature of the environment or the optical cable itself. When the environmental temperature is normal or the temperature of the optical cable itself is also within the normal working range, the surface of the fusible shielding part 301d is coated with a light shielding coating, and the signal between the signal receiving optical fiber and the signal emitting optical fiber is shielded and cannot be received by each other, so no high-temperature alarm will be performed.
