[0019] To achieve the foregoing and related objectives, the present invention includes the features fully described below and particularly pointed out in the claims. Certain illustrative aspects and embodiments of the invention are set forth in detail in the following description and drawings. However, these are merely indications of a few of the various ways in which the principles of the invention can be employed. Other objects, advantages, and novel features of the invention will become apparent when considered in conjunction with the accompanying drawings and the following detailed description based on the invention.

[0020] It should be noted that, in order to avoid obscuring the present application with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present application are shown in the drawings, while other details not relevant to the present application are omitted.

[0021] The embodiment of the present application first provides a long-distance high-level water supply system, as shown in Figure 1 , the water supply system mainly comprises a control unit 4, a high-level water storage tank 1, a plurality of water supplement units 2 connected with the high-level water storage tank 1, and a plurality of water collection units 3 connected with each of the water supplement units 2, and the high-level water storage tank 1 is provided with a first water level monitoring device 51.

[0022] As shown in Figure 1 , the water supplement unit 2 comprises a low-level water collection tank 21, which is connected to the high-level water storage tank 1 through a pressurizing pump 22 and a water supplement pipeline 23, and the low-level water collection tank 21 is provided with a second water level monitoring device 52.

[0023] As shown in Figure 1 , the water collection unit 3 comprises a water well 31 around the low-level water collection tank 21, which is connected to the low-level water collection tank 21 through a water pumping pump 32 and a water pumping pipeline 33, and the water well 31 is provided with a third water level monitoring device 53.

[0024] Among them, the high-level water storage tank 1 is arranged in the mining area in the wild, the low-level water collection tank 21 and the water well 31 are arranged in the water source, and the position of the high-level water storage tank 1 is relatively high and far away from the low-level water collection tank 21.

[0025] Among them, the control unit 4 is electrically connected with the first water level monitoring device 51, the second water level monitoring device 52, the third water level monitoring device 53, the pressurizing pump 22 and the water pumping pump 32 respectively, so as to realize the receiving of detection signal and the issuing of control instruction. The control unit 4 is configured to control the water supplement unit 2 to supplement water to the high-level water storage tank 1 based on the water level state monitored by the first water level monitoring device 51 and the second water level monitoring device 52, and to control the water collection unit 3 to supplement water to the low-level water collection tank 2 based on the water level state monitored by the second water level monitoring device 52 and the third water level monitoring device 53.

[0026] The control method of the long-distance high-level water supply system as described above comprises controlling the water supplement to the high-level water storage tank 1 and controlling the water supplement to the low-level water collection tank 21.

[0027] Specifically, the control of water replenishment to the high-level reservoir 1 comprises: the control unit 4 confirms the water level state of the high-level reservoir 1 based on the first water level monitoring device 51, and confirms the water level of each low-level water collector 21 based on the second water level monitoring device 52 in each water replenishment unit 2, if the water level of the high-level reservoir 1 is lower than the first low water level threshold and there is a first low-level water collector 21 whose water level is greater than the second low water level threshold, the corresponding pressurized pump 22 of the first low-level water collector 21 is controlled to be turned on to replenish water to the high-level reservoir 1; if the water level of the high-level reservoir 1 reaches above the first low water level threshold, water replenishment is not needed. It should be noted that the above-mentioned first low-level water collector 21 refers to the low-level water collector whose water level is greater than the second low water level threshold (which has sufficient water to replenish the high-level reservoir 1), which is different from other low-level water collectors whose water level is less than the second low water level threshold.

[0028] Further, in the above process of replenishing water to the high-level reservoir 1: if the water level of any one of the first low-level water collectors 21 decreases to below the second low water level threshold, the corresponding pressurized pump 22 of the first low-level water collector 21 is controlled to be turned off, thereby stopping the action of the first low-level water collector 21 to replenish water to the high-level reservoir 1, and other first low-level water collectors 21 whose water level is still greater than the second low water level threshold continue to replenish water to the high-level reservoir 1. If the water level of the high-level reservoir 1 rises to the first high water level threshold, the corresponding pressurized pump 22 of all first low-level water collectors 21 is controlled to be turned off, and the replenishment of water to the high-level reservoir 1 is stopped.

[0029] Specifically, the control of water replenishment to the low-level water collector 21 comprises: for any one of the low-level water collectors 21 of the water replenishment unit 2, the control unit 4 confirms the water level state of the low-level water collector 21 based on the second water level monitoring device 52, and confirms the water level of each water well 31 based on the third water level monitoring device 53 in each water collector unit 3, if the water level of the low-level water collector 21 is lower than the second low water level threshold and there is a first water well 31 whose water level is greater than the third low water level threshold, the corresponding water pumping pump 32 of the first water well 31 is controlled to be turned on to replenish water to the low-level water collector 21; if the water level of the low-level water collector 21 reaches above the second low water level threshold, water replenishment is not needed. It should be noted that the above-mentioned first water well 31 refers to the water well whose water level is greater than the third low water level threshold (which has sufficient water to replenish the low-level water collector 21), which is different from other water wells whose water level is less than the third low water level threshold.

[0030] Further, in the above process of replenishing water to the low-level water pool 21: if the water level of any one of the first water wells 31 is lowered to below the third low water level threshold, the control unit 4 controls the corresponding water pump 32 to be closed, thereby stopping the first water well 31 from replenishing water to the low-level water pool 21, and the first water wells 31 whose water levels are still greater than the third low water level threshold continue to replenish water to the low-level water pool 21. If the water level of the low-level water pool 21 is raised to the second high water level threshold, the control unit 4 controls all the corresponding water pumps 32 to be closed, thereby stopping the replenishment of water to the low-level water pool 21.

[0031] The control unit 4 can be a local control unit (LCU) integrated into the mining area, and the first low water level threshold and the first high water level threshold corresponding to the high-level water pool 1, the second low water level threshold and the second high water level threshold corresponding to the low-level water pool 21, and the third low water level threshold corresponding to the vertical well 31 are respectively preset in the control unit 4. The first water level monitoring device 51, the second water level monitoring device 52, and the third water level monitoring device 53 can be ultrasonic liquid level sensors.

[0032] In a preferred embodiment, the number of the water replenishing units 2 connected to the high-level water pool 1 can be 4-6, and the number of the water collecting units 3 connected to each water replenishing unit 2 can be 4-6.

[0033] In a preferred embodiment, as shown in Figure 1 The remote high-level water supply system further comprises a first electrically controlled valve 24 arranged on the water replenishing pipeline 23 and a second electrically controlled valve 34 arranged on the water pumping pipeline 33, and the control unit 4 is electrically connected to the first electrically controlled valve 24 and the second electrically controlled valve 34. The control method of the water supply system further comprises: for any one of the water replenishing units 2, before controlling the corresponding pressurized pump 22 to be opened, the control unit 4 controls the first electrically controlled valve 24 to be in an open state; and after controlling the corresponding pressurized pump 22 to be closed, the control unit 4 controls the first electrically controlled valve 24 to be in a closed state. For any one of the water collecting units 3, before controlling the corresponding water pump 32 to be opened, the control unit 4 controls the second electrically controlled valve 34 to be in an open state; and after controlling the corresponding water pump 32 to be closed, the control unit 4 controls the second electrically controlled valve 34 to be in a closed state.

[0034] In a preferred embodiment, as shown in Figure 1As shown, the remote high-level water supply system, the water replenishment pipeline 23 is further provided with a first flow meter 25, the water pumping pipeline 33 is further provided with a second flow meter 35, and the control unit 4 is electrically connected with the first flow meter 25 and the second flow meter 35 respectively. The control method of the water supply system further comprises: for any one of the water replenishment units 2, the control unit 4 confirms whether the low-level water collection tank 21 and the high-level water storage tank 1 are effectively connected or closed based on the flow information fed back by the first flow meter 25; and for any one of the water collection units 3, the control unit 4 confirms whether the water well 31 and the low-level water collection tank 21 are effectively connected or closed based on the flow information fed back by the second flow meter 35.

[0035] For example, in the process of replenishing water to the high-level water storage tank 1, if the first electric control valve 24 corresponding to one of the water replenishment units 2 is opened and the pressure pump 22 is started to replenish water, and the flow fed back by the first flow meter 25 reaches the normal flow, it is confirmed that the low-level water collection tank 21 and the high-level water storage tank 1 are effectively connected, otherwise, there is an abnormal situation in the water replenishment line, the control unit 4 controls the pressure pump 22 and the first electric control valve 24 to be closed in sequence, and an abnormal alarm is sent to remind the staff to troubleshoot. If the pressure pump 22 and the first electric control valve 24 corresponding to one of the water replenishment units 2 are closed in sequence, and the flow fed back by the first flow meter 25 is 0, it is confirmed that the low-level water collection tank 21 and the high-level water storage tank 1 are effectively closed, and the instruction to stop replenishing water can be normally executed, otherwise, there is an abnormal situation in the water replenishment line, and the control unit 4 sends an abnormal alarm to remind the staff to troubleshoot.

[0036] In summary, the remote high-level water supply system and the control method thereof provided by the above embodiments set a water well and a low-level water collection tank at a water source, set a high-level water storage tank at a mining area, set a water supply pipeline between the high-level water storage tank and the low-level water collection tank, and build a remote high-level water supply system; the water replenishment actions of the high-level water storage tank and the low-level water collection tank are automatically controlled by the control unit based on the water level states of the high-level water storage tank, the low-level water collection tank and the water well, which solves the problem of automatic control of water supply in the mining area and effectively meets the demand for production and living water in the mining area. Moreover, the water supply system and the control method thereof can be applied to replenish water for large-capacity water tanks in various industrial and mining enterprises, and have the advantages of stable operation, flexible control, low labor cost and the like.

[0037] The above description is merely a specific implementation of the present application, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
