Description

Technical Field

[0001] The utility model relates to an alarm device, in particular to an iron ore shaft full warehouse alarm device. Background Art

[0002] The iron ore hoisted in the shaft has the characteristics of different shapes, heavy weight and strong impact force, large dust and different colors. Therefore, it is impossible to use the existing storage position over-limit protection alarm device on the market like coal mines. Originally, it could only be handled by manually observing the storage position in real time through the monitor. Since the mining area is located in a high-altitude area, there is heavy fog that affects the monitoring field of view, and the personnel are easily tired and lack of concentration at night. After the shaft is full of ore, it is not discovered in time and the ore is continued to be lifted, resulting in the ore being full and poured into the bottom of the shaft through the unloading port. In the process of pouring the ore into the bottom of the shaft, the shaft wall, control line, optical fiber and high-voltage cable in the shaft are damaged to varying degrees or directly damaged. Replacing new cables and optical fibers requires a large amount of maintenance funds, which will further lead to production suspension and increase safety accidents. Summary of the invention

[0003] In view of the deficiencies of the above-mentioned problems, the utility model provides an iron ore shaft full warehouse alarm device.

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: an iron ore shaft full warehouse alarm device, including a warehouse body, a high-sensitivity infrared sensor and a control system, the high-sensitivity infrared sensor is arranged on one side of the inner wall of the warehouse body, the control system includes a relay, a delay relay and an alarm, the relay is electrically connected to the high-sensitivity infrared sensor, the delay relay is electrically connected to the relay, the delay relay is electrically connected to the alarm, and the alarm can receive the signal of the delay relay to generate a delayed alarm.

[0005] Preferably, the control system further comprises a delayed alarm device, which is electrically connected to the alarm and can cause the alarm to sound a delayed alarm.

[0006] Preferably, two highly sensitive infrared sensors are provided, and the two highly sensitive infrared sensors are respectively provided on both sides of the inner wall of the warehouse body, and the two highly sensitive infrared sensors are respectively provided with the corresponding control system.

[0007] Preferably, a release switch is provided in the alarm.

[0008] Preferably, the alarm is an electric bell or a flashing alarm.

[0009] The beneficial effects of the utility model are:

[0010] 1. Through the setting of high-sensitivity infrared sensor and non-contact high-sensitivity infrared sensor, it can sense at a long distance without fear of ore impact damage; through the setting of delay relay, it can avoid frequent alarm every time the ore passes in front of the sensor. The delay switch action time set by the delay relay is longer than the unloading process time, and the alarm will not work until the set time is reached; through the setting of delay alarm device, the delay time set by the delay alarm device is longer than the discharge time, so as to avoid the alarm during the normal ore lifting process; through the setting of release switch, the alarm is automatically released after a certain time set by the release switch, and the alarm stops working, so as to avoid interference caused by long-term alarm of the alarm; such setting not only saves the funds for large-scale repairs such as replacing cables and optical fibers, but also avoids production stoppage caused by full warehouses and reduces the occurrence of safety accidents.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1 and Figure 2As shown, an iron ore shaft full warehouse alarm device includes a warehouse body 1, a highly sensitive infrared sensor 2 and a control system 3. The highly sensitive infrared sensor 2 is arranged on one side of the inner wall of the warehouse body 1. The control system 3 includes a relay, a time delay relay and an alarm 4. The relay is electrically connected to the highly sensitive infrared sensor 2, the time delay relay is electrically connected to the relay, the time delay relay is electrically connected to the alarm 4, the alarm 4 can receive the signal of the time delay relay to generate a delayed alarm, the control system 3 also includes a delayed alarm device, the delayed alarm device is electrically connected to the alarm 4, the delayed alarm device can cause the alarm 4 to delay the alarm, two highly sensitive infrared sensors 2 are provided, the two highly sensitive infrared sensors 2 are respectively arranged on both sides of the inner wall of the warehouse body 1, the two highly sensitive infrared sensors 2 are respectively provided with corresponding control systems, a release switch is provided in the alarm 4, and the alarm 4 is an electric bell or a flash alarm. By adopting this structure, the non-contact high-sensitivity infrared sensor 2 can sense at a long distance without being afraid of damage caused by ore impact. The delay relay set can avoid frequent alarms every time the ore passes in front of the sensor. The delay switch action time set by the delay relay is longer than the unloading process time. The alarm 4 will not work until the set time is reached. The delay time set by the delay alarm device is longer than the ore discharge time, which avoids the alarm 4 from sounding during normal ore lifting. The alarm is automatically released after a certain period of time set by the release switch, and the alarm 4 stops working, avoiding interference caused by long-term alarms of the alarm 4. The two high-sensitivity infrared sensors 2 can effectively avoid missed reports.

[0016] When in use, adjust the sensing distance of the high-sensitivity infrared sensor 2 according to the current situation. After setting the full warehouse position, the warehouse body 1 is full of ore and blocks the designed circuit of the high-sensitivity infrared sensor 2, and then actuates. The normally open point action relay works, and the delay switch action time set by the delay relay is longer than the unloading process time. Normal unloading is started. When the warehouse is full, when the delay switch action set by the delay relay reaches the set time, the delay alarm device receives the relay signal and starts. The delay time set by the delay alarm device is greater than the discharge time. When the delay time set by the delay alarm device is reached, the alarm 4 works. When the alarm 4 starts working, the release switch is started. When the alarm reaches a certain time set by the release switch, the alarm is automatically released and the alarm 4 stops working.

[0017] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
