This invention provides a cross-seasonal natural ice-making winter cold storage energy storage mine cooling system, belonging to the field of mine heat hazard control technology. It includes a cold storage subsystem and an underground cooling subsystem, coupled via a four-way reversing valve. The cold storage subsystem includes an ice storage tank, a water supply assembly, and a spray enhancement module. The outlet of the ice storage tank is connected to the inlet of the water supply assembly, and the outlet of the water supply assembly is connected to the first interface of the four-way reversing valve. The spray enhancement module is connected to the second interface of the four-way reversing valve. The underground cooling subsystem includes an air cooler, a second fan, a chilled water pipe, and a return water pipe. One end of the chilled water pipe is connected to the third interface of the four-way reversing valve, and the other end is connected to the inlet of the air cooler. The outlet of the air cooler is connected to the return water pipe, and the end of the return water pipe furthest from the air cooler is connected to the fourth interface of the four-way reversing valve. This mine cooling system has a simple structure, low energy consumption, low cost, and high energy storage efficiency.

This utility model relates to the field of water storage tank technology, and in particular to a high-pressure water gun level control device, including a water tank and a housing installed inside the water tank. The top of the housing is connected to an inlet pipe extending to the outside of the water tank. A filter cylinder with an open bottom is fixed inside the housing, and a filter screen is fixed on the outer wall of the filter cylinder. A piston tube is fixed at the center of the bottom of the housing, and an automatic water replenishment mechanism is provided at the bottom of the piston tube. A filter screen is fixed on the outer wall of the filter cylinder, and a filter screen cleaning mechanism connected to the automatic water replenishment mechanism is provided on the outside of the filter cylinder. This high-pressure water gun level control device can trap impurities in the water, preventing impurities from entering the piston tube and causing water replenishment blockage, thus reducing the mechanical failure rate. It can also clean impurities on the filter screen, preventing impurities from clogging the filter screen and causing poor water replenishment. Furthermore, subsequent maintenance only requires opening the valve on the drain pipe to discharge impurities, making it easy to maintain and simple to operate.
