Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, and in particular to a water level monitoring and early warning device for coal mine water tanks. Background Technology

[0002] Coal mine water tanks are an important part of the underground drainage system in coal mines. They are chambers excavated underground specifically to store mine water. During underground mining, groundwater may gush out. If the water level in the water tank is too high and exceeds the effective capacity of the water tank, the mine may be flooded. This will not only damage underground electrical equipment and mining equipment, but also threaten the lives of underground workers. Therefore, water level monitoring is necessary.

[0003] Currently, existing devices (such as announcement number: CN221882727U) disclose a water level monitoring and early warning device. This device starts a motor, which drives a first gear to rotate via a rotating rod. The first gear drives a second gear to rotate, which in turn drives a connecting rod to rotate. The connecting rod drives a connecting seat to rotate, and the connecting seat drives an extension rod to rotate. This allows the extension rod to move away from the water surface and above the ground, facilitating the installation of an ultrasonic water level gauge. After the ultrasonic water level gauge is installed, the extension rod is rotated with the ultrasonic water level gauge above the water surface to facilitate water level monitoring and early warning.

[0004] However, during the implementation of the above technical solutions, at least the following technical problems were found: In the coal mine water tank environment, the geological conditions of the area where the water level monitoring and early warning device is installed are usually relatively soft. Over time, due to the combined effects of factors such as the impact of water flow in the water tank, water level fluctuations, and the weight of the device itself, the installation area is prone to loosening. This makes it impossible for the water level sensor to maintain a parallel state with the water surface, resulting in a large deviation in the water level data monitored by the water level sensor, making it impossible to issue timely warnings, and the safety is insufficient and needs to be improved. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a coal mine water level monitoring and early warning device, which solves the technical problem of insufficient safety of existing devices.

[0009] The early warning device comprises a mounting rod, both ends of the mounting rod are exposed outside the mounting column, an inclination sensor for measuring the angle is fixedly installed on the upper end of the mounting rod, and a water level sensor for monitoring the water level is fixedly installed on the lower end of the mounting rod.

[0010] Preferably, a threaded groove is formed in the fixed column, an externally threaded column is threadedly installed in the threaded groove, the externally threaded column is fixedly installed with the rotating column, a rotary joint is arranged on the side wall of the rotating column away from the mounting column, and the rotary joint is located on the inner side of the externally threaded column.

[0011] Preferably, two sliding grooves are symmetrically formed in the circumferential surface of the fixed column, two sliding blocks are slidingly installed in the two sliding grooves, and connecting rods are fixedly installed between the two sliding blocks and the mounting column.

[0012] Preferably, a power supply unit for power supply is arranged on the side wall of the base, a transmission unit for signal transmission is arranged on the side wall of the base, and a control unit for controlling the inclination sensor and the water level sensor is arranged on the side wall of the base.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] In the utility model, when the anchor rod and the inner wall of the water sump are connected loose, the base as a whole will change in angle, at the same time, the inclination sensor will monitor and transmit data to the control unit, so that the control unit sends a signal to the transmission unit, the transmission unit sends an alarm to the staff in time for adjustment, thereby ensuring the parallelism of the water level sensor and the water surface, improving the accuracy of the water level sensor in monitoring the water level, and improving safety.

[0015] In the utility model, by rotating the rotating column, the rotating column drives the externally threaded column to rotate and threadedly drives the inside of the threaded groove, so that the externally threaded column moves to the side of the mounting column, at this time, the externally threaded column, the rotating column and the mounting column will extend to the outside of the fixed column, thereby facilitating additional adjustment of the water level sensor in the coal mine water sump, so as to conveniently find the most suitable water level measurement area and improve convenience.

[0022] This application provides a coal mine water level monitoring and early warning device, effectively solving the technical problem of insufficient safety in existing devices. By setting up an early warning device, when the connection between the anchor rod and the inner wall of the water tank becomes loose, the angle of the entire base will change. At the same time, the tilt sensor will detect this and transmit the data to the control unit. The control unit will then send a signal to the transmission unit, causing the transmission unit to issue an alarm to the staff for timely adjustment. This ensures the parallelism between the water level sensor and the water surface, improves the accuracy of water level monitoring, and enhances safety. Furthermore, by rotating the rotating column, the external threaded column is driven to rotate and undergoes threaded transmission within the threaded groove. This causes the external threaded column to move towards the mounting column. At this time, the external threaded column, rotating column, and mounting column will extend outward from the fixed column, facilitating additional adjustments to the water level sensor inside the coal mine water tank. This makes it easier to find the most suitable water level measurement area and improves convenience.
