Description

Technical Field

[0001] This utility model relates to the field of storage space warning technology, and in particular to a storage space warning device for underground ore storage bins. Background Technology

[0002] Traditionally, the positions of underground ore storage bins are mostly observed manually, which is quite cumbersome. In order to prevent the underground ore storage bins from emptying, a certain height of ore needs to be stored inside the underground ore storage bins. This is to prevent ore from falling from the upper part of the underground ore storage bin (ranging from 12 / 30 / 48 meters) from directly hitting the bottom plate of the underground ore storage bin. The huge impact force will cause serious damage to the underground ore storage bin itself. In addition, the rapidly falling ore will generate flying rocks at the underground ore storage bin's leak, which will pose a serious threat to on-site workers and create safety hazards.

[0003] Therefore, it is necessary to provide a new underground ore storage bin level warning device to solve the above-mentioned technical problems. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of the underground ore storage bin position warning device provided by this utility model; Figure 2 Circuit diagram showing the connection between the limit switch and LED light of the underground ore storage bin level warning device provided by this utility model; Figure 3This utility model provides a schematic diagram showing the connection between the limit switch and the contactor coil of the vibration motor in the underground ore storage bin position warning device. The underground ore storage bin position warning device includes: a mounting frame 2 installed on the outer wall of the underground ore storage bin 1; a connecting rod 3 slidably installed inside the mounting frame 2; a wedge-shaped pusher 5 fixedly installed at one end of the connecting rod 3; the wedge-shaped pusher 5 extending into the underground ore storage bin wall 1; a compression spring 4 sleeved on the outer side of the connecting rod 3; the two ends of the compression spring 4 being connected to the wedge-shaped pusher 5 and the mounting frame 2 respectively; a pressing plate 7 hinged to the inner wall of the underground ore storage bin 1; the pressing plate 7 contacting the wedge-shaped pusher 5; and a limit switch 8 provided on the side of the mounting frame 2 away from the underground ore storage bin wall 1, the limit switch 8 being adapted to the connecting rod 3.

[0019] One end of the normally closed contact 81 of the limit switch 8 is connected to one end of the first LED 10, and one end of the normally open contact 82 of the limit switch 8 is connected to one end of the second LED 11. The other ends of the normally closed contact 81 and the other ends of the normally open contact 82 are both connected to one end of a 200V AC power supply. The other ends of the first LED 10 and the second LED 11 are both connected to the other end of the 200V AC power supply.

[0020] The first LED 10 is red, and the second LED 11 is green.

[0021] The normally open contact 82 is connected to the contactor coil of the vibration motor. When the normally open contact 82 is closed, the contactor coil of the vibration motor is energized and the vibration motor starts to work.

[0023] An installation block 6 is fixedly installed on the inner wall of the underground ore storage bin 1, and the extrusion plate 7 is hinged to the installation block 6.

[0024] In this embodiment, when the underground ore storage bin is full: the extrusion plate 7 is pushed by the extrusion force of the ore to rotate on the mounting block 6. The extrusion plate 7 pushes the wedge-shaped pusher 5 to push the connecting rod 3 to slide on the mounting frame 2. The compression spring 4 is compressed, the connecting rod 3 contacts the forming switch, and triggers the limit switch 8, causing the normally open contact 82 of the limit switch 8 to close: the second LED light 11 lights up to indicate (full leakage). At the same time, the normally open contact 8 closes to provide the closing condition for the vibration motor contactor coil, and the normally closed contact opens to turn off the red light (no empty leakage is indicated).

[0025] When the ore chamber in the drain is empty: the external force of the ore compression disappears, and the entire device resets under the elastic force of the compression spring 4. The normally closed contact 81 returns to its closed position, causing the red light to illuminate (empty drain). At the same time, the normally open contact 82 opens, causing the green light to turn off (not indicating full drain) and the vibration motor to be de-energized to prevent the vibration motor from being accidentally started when the drain is empty.

[0026] Compared with related technologies, the underground ore storage bin level warning device provided by this utility model has the following beneficial effects:

[0027] This utility model provides a ore storage bin level warning device. The mounting bracket 2 facilitates the installation of the compression spring 4 and the connecting rod 3.
