TECHNICAL FIELD

[0002] In a mine working face, hydraulic supports serve as key support equipment, and their stability and working efficiency are crucial for ensuring mine safety and improving production efficiency. Traditional mine working face support hydraulic systems usually adopt a centralized liquid supply mode. In this mode, a hydraulic pump station is arranged at a specific position, and high-pressure liquid is delivered to each support through a series of pipelines. However, with the increase of mining depth and the continuous expansion of mining scale, this centralized liquid supply mode exposes many problems.

[0003] However, the traditional centralized liquid supply mode of hydraulic supports cannot guarantee the timeliness and stability of liquid supply when the working face supports move quickly and act frequently. Especially when the supports are moved quickly, the problems of pressure fluctuation and insufficient flow of the liquid supply system are particularly prominent. Moreover, the existing centralized liquid supply system supplies liquid to the entire support through the system when working, which cannot supply liquid to a single hydraulic rod, so that the extension size of the single hydraulic rod is uncontrollable, and the extension accuracy of the single hydraulic rod is low. Therefore, the application provides a distributed energy storage liquid supply system for a mine working face support. SUMMARY

Figures 8-9 , Figure 12Each of the liquid storage tanks 5 is provided with a pneumatic motor 408 at its lower end, which is fixedly connected to the oil delivery pipe 401. The pneumatic motor 408 can drive the pneumatic plate 409 to rotate. Each oil delivery pipe 401 has a pneumatic plate 409 inside, which is made of alloy material. The pneumatic plate 409 can control the amount of hydraulic oil entering the liquid storage tank 5 by rotating, thereby changing the internal pressure of the liquid storage tank 5 and ensuring the rate of hydraulic oil delivery. Each pneumatic motor 408 is rotatably connected to the pneumatic plate 409 at its right end. Each oil delivery pipe 401 and its external valve seat 403 are fixedly connected by the pneumatic motor 408. Each valve seat 403 is connected to the hydraulic accumulator at its upper end by a pressure ring 404. The device 4 is fastened together. The pressure ring 404 is used to lock the pressure ring 404 and the hydraulic accumulator 4. Each hydraulic accumulator 4 has a positioning plate 406 fixed at its upper end. The positioning plate 406 is made of alloy material and is used to position the air intake pipe 6. Each positioning plate 406 is fastened to the air intake pipe 6 at its upper end by a stop nut 407. The stop nut 407 is used to position the air intake pipe 6 and the positioning plate 406. Each positioning plate 406 has two protective cover moving rods 601 fixed at its upper end. The protective cover moving rods 601 are telescopic, which can drive the protective cover positioning plate 602 to move, thereby facilitating air to enter the air intake pipe 6 through the filter plate 606. A protective cover positioning plate 602 is fixed to the upper end of the protective cover moving rod 601. The protective cover positioning plate 602 is made of alloy material and is used to position the protective cover 603. Each protective cover positioning plate 602 is also fixedly connected to the protective cover 603 at its lower end. A sealing ring 604 is fixed to the lower end of each protective cover 603. The sealing ring 604 is made of rubber material and can ensure the seal between the protective cover 603 and the air inlet pipe 6. A filter plate 606 is fixed to the upper end of each air inlet pipe 6 to prevent coal dust from entering the air inlet pipe 6. A cleaning rod 607 is provided at the upper end of each filter plate 606. The cleaning rod 607 is made of alloy material. Rod 607 is used to clean coal dust from the surface of filter plate 606, thereby ensuring the stability of gas transmission. A cleaning motor 608 is fixed to the lower end of each filter plate 606. The cleaning motor 608 can drive the cleaning rod 607 to rotate. Each cleaning motor 608 is rotatably connected to the cleaning rod 607 at its upper end. An air pump 609 is installed inside each air inlet pipe. An air pump 609 is fixed to the lower end of its lower end with an air valve 610. The air pump 609 and the air valve 610 cooperate to deliver air from inside the air inlet pipe 6 to the air bag 611. The lower end of each air valve 610 is fixedly connected to the air bag 611 via a pipe. An air outlet valve 605 is also fixed to the left end of the pipe at the lower end of each air valve 610.The vent valve 605 facilitates the release of air from inside the airbag 611; When it is necessary to transfer the hydraulic oil inside the reservoir 5 to the flow control pipe 7, the controller 101 controls the extension and retraction of the protective cover moving rod 601, thereby moving the protective cover positioning plate 602, which in turn moves the protective cover 603, causing the filter plate 606 to open. At this time, the controller 101 controls the air pump 609 and the air valve 610 to work together, thereby causing the airbag 611 to deform, so that the hydraulic oil inside the hydraulic accumulator 4 is transferred to the reservoir 5 through the oil delivery pipe 401. At this time, the oil delivery pipe 401 controls the air delivery motor 408 to work, thereby driving the air delivery plate 409 to rotate, thus facilitating the entry of the hydraulic oil inside the oil delivery pipe 401 into the reservoir 5. Simultaneously, the amount of oil entering the reservoir 5 can be controlled to ensure the accuracy of hydraulic oil delivery. When the air intake of the airbag 611 is small, the controller 101 controls the cleaning motor 608 to work, thereby driving the cleaning rod 607 to rotate, thus cleaning the coal dust on the surface of the filter plate 606. When energy storage is required, the controller 101 controls the air outlet valve 605 to open, thereby expelling the air inside the airbag 611 and filling the hydraulic accumulator 4 with hydraulic oil, thus facilitating the next round of energy release. At this time, the controller 101 controls the protective cover moving rod 601 to work in reverse, thereby making the sealing ring 604 and the air inlet pipe 6 tightly adhere, thus preventing air from entering and preventing coal dust from clogging the filter plate 606.

Each positioning ring 715 has a flow control ring positioning rod 710 slidably connected inside. The flow control ring positioning rod 710 is made of alloy material. The flow control ring positioning rod 710 is used to position the flow control ring positioning rod 710, thereby ensuring that the flow control internal gear 708 and the flow control auxiliary gear 711 are always meshed. A stabilizing plate 706 is fixed to the left end of each set of flow control ring positioning rods 710. The stabilizing plate 706 is made of alloy material and is used to position the flow control ring positioning rod 710. Each stabilizing plate 706 is fixedly connected to the external flow control tube 7. Each flow control ring 707 also has a flow control external tooth 709 fixed to its exterior. The flow control external tooth 709 can drive the flow control internal tooth 708 to rotate by rotating. Each flow control external tooth 709 is meshed with a flow control main gear 714, which can drive the flow control external tooth 709 to rotate. A flow control motor 713 is rotatably connected to the left end of each flow control main gear 714, which can drive the flow control main gear 714 to rotate. Each flow control motor 713 is fixedly connected to its external flow control pipe 7. Each flow control pipe 7 has an exhaust camera 803 at its bottom, which is fixedly connected to the return pipe 8. The exhaust camera 803 monitors the air output of the exhaust valve 802. Each return pipe 8 has a return valve 801 fixed to its right end. The return valve 801 controls the hydraulic oil inside the return pipe 8 to enter the reservoir 5, thus completing the return flow. Each return valve 801 is fixedly connected to its right-side hydraulic pipeline 9 via a pipe. Each return pipe 8 also has an exhaust valve 802 fixed to its upper end. The exhaust valve 802 controls gas leakage inside the return pipe 8, thereby ensuring the accuracy of hydraulic oil delivery.Each of the return pipes 8 and each of the output pipes 702 has several diversion pipes 905 fixed to its left end. The diversion pipes 905 are made of alloy material and are used to position the hydraulic line 9 at their left end. Each diversion pipe 905 is securely connected to its left-end hydraulic line 9 via a diversion pipe hydraulic sensor 902. A diversion pipe hydraulic sensor 902 is fixed inside each diversion pipe 905 and is used to monitor the diversion pipe 905. 05. Internal hydraulic system: Each of the flow dividers 905 has a flow divider plate 904 inside, which is made of alloy material. This allows for control of the flow rate inside the flow divider 905, achieving precise oil delivery and ensuring the accuracy of the hydraulic rod's extension and retraction. A flow divider motor 903 is fixed inside each flow divider 905, driving the flow divider plate 904 to rotate. Each flow divider motor 903 is rotatably connected to one end of the flow divider plate 904 via a rotating shaft. Before using this device, the controller 101 controls all the diverter plates 904 to open, thereby allowing hydraulic oil to move along the oil pipes and then enter the return pipe 8 through the hydraulic line 9 at the left end of the return pipe 8. At this time, the controller 101 controls multiple vent valves 802 to open, thereby venting the air inside the oil pipes, thus ensuring the extension and retraction stability of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205. When the balancing hydraulic rod 204 and the side guard plate hydraulic rod 205 need to extend, the hydraulic oil inside the reservoir 5, due to the deformation of the air bladder 611, can enter the flow control pipe 7 through the outlet pipe 701, and further be delivered to several of the diversion pipes 905 through the output pipe 702. At this time, the controller 101 controls several of the diversion motors 903 to work according to the different extension and retraction dimensions of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balancing hydraulic rod 204, and the side guard plate hydraulic rod 205, thereby driving several of the diversion plates 904 to rotate. Hydraulic oil is allowed to enter several of the diversion pipes 905. At this time, the hydraulic sensors 902 of the diversion pipes transmit the oil pressure to the controller 101. The controller 101 then controls the opening angles of several diversion plates 904 according to the required extension length of the hydraulic rod, thereby ensuring controllable oil flow. The flow meter 703 monitors the hydraulic oil flow rate inside the flow control pipe 7. The controller 101 then controls the flow control motor 713 to operate based on the sum of the oil pressures from the hydraulic sensors 902 and the oil pressure from the hydraulic sensor 704, thereby driving the flow control main gear 714 to rotate, which in turn drives the... The external flow control gear 709 rotates, which in turn drives the internal flow control gear 708 to rotate, which in turn drives the secondary flow control gear 711 to rotate, which in turn drives the flow control plate 712 to rotate, thereby controlling the hydraulic oil flow of the flow control pipe 7. This balances the internal oil pressure of the output pipe 702 and several of the branch pipes 905, ensuring the stability of the output pipe 702 and achieving precise oil delivery. This also ensures the accuracy of the extension and retraction of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205, thereby ensuring the accuracy of the support.

[0024] The workflow of this invention is as follows: When using this device, the operator places the entire device in the required support position. The operator then connects the infusion head 301 to an external liquid supply source. At this time, the controller 101, in cooperation with the high-pressure pump 3 and the infusion valve 302, delivers external hydraulic oil through the infusion pipe 303 and the connecting pipe 304 to the two storage tanks 5, thereby achieving energy storage. The controller 101 controls all the diverter plates 904 to open, allowing the hydraulic oil to move along the oil pipe and then enter the return pipe 8 through the hydraulic line 9 at the left end of the return pipe 8. At this time, the controller 101 controls multiple vent valves 802 to open, thereby venting air from inside the oil pipe. This ensures the telescopic stability of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205. The controller 101 controls all the diverter plates 904 to open, allowing hydraulic oil to move along the oil pipes and then enter the return pipe 8 through the hydraulic line 9 at the left end of the return pipe 8. At this time, the controller 101 controls multiple exhaust valves 802 to open, thereby venting the air inside the oil pipes, thus ensuring the telescopic stability of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205. When supporting coal mine roadways, and when it is necessary to transport hydraulic oil from the storage tank 5 to the flow control pipe 7, the controller 101 controls the extension and retraction of the protective cover moving rod 601, thereby moving the protective cover positioning plate 602, which in turn moves the protective cover 603, causing the filter plate 606 to open. At this time, the controller 101 controls the air pump 609 and the air valve 610 to work together, thereby causing the airbag 611 to deform, so that the hydraulic oil inside the hydraulic accumulator 4 is transported to the storage tank 5 through the oil delivery pipe 401. At this time, the oil delivery pipe 401 controls the air delivery motor 408 to work, thereby driving the air delivery plate 409 to rotate, from... This facilitates the entry of hydraulic oil from the oil supply pipe 401 into the reservoir 5, while also controlling the amount of oil entering the reservoir 5 to ensure accurate hydraulic oil delivery. When the air intake of the airbag 611 is small, the controller 101 controls the cleaning motor 608 to operate, thereby driving the cleaning rod 607 to rotate, thus cleaning the coal dust on the surface of the filter plate 606. When the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205 need to extend, the hydraulic oil inside the reservoir 5 can enter the flow control pipe 7 through the outlet pipe 701 due to the deformation of the airbag 611.The hydraulic oil is further supplied to several diversion pipes 905 via the output pipe 702. At this time, the controller 101 controls several diversion motors 903 to operate according to the different extension and retraction dimensions of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205. This drives several diversion plates 904 to rotate, allowing hydraulic oil to enter several diversion pipes 905. At this time, several diversion pipe hydraulic sensors 902 transmit the oil pressure to the controller 101. The controller 101 then controls several diversion pipes according to the required extension dimensions of the hydraulic rods. The plate 904 opens at different angles to ensure controllable oil flow. At this time, the flow meter 703 monitors the hydraulic oil flow inside the flow control pipe 7. The controller 101, based on the sum of the oil pressures from several branch pipe hydraulic sensors 902 and the oil pressure from the hydraulic sensor 704, controls the flow control motor 713 to operate, thereby driving the flow control main gear 714 to rotate, which in turn drives the flow control external gear 709 to rotate, which in turn drives the flow control internal gear 708 to rotate, which in turn drives the flow control secondary gear 711 to rotate, which in turn drives the flow control plate 712 to rotate, thus controlling the hydraulic oil flow in the flow control pipe 7. This ensures the oil pressure balance within the output pipe 702 and the several branch pipes 905, thereby guaranteeing the stability of the output pipe 702 and achieving precise oil delivery. It also ensures the accuracy of the extension and retraction of the left column hydraulic rod 2, the right column hydraulic rod 201, the shield beam hydraulic rod 203, the balance hydraulic rod 204, and the side guard plate hydraulic rod 205, thus guaranteeing accurate support. Furthermore, by coordinating the left column hydraulic rod 2 and the right column hydraulic rod 201, the operator can move the top beam 106 up and down, thereby supporting the coal mine roadway. Furthermore, the extension and retraction of the shield beam hydraulic rod 203 can drive the tail beam 104 to rotate. The extension and retraction of the balance hydraulic rod 204 drives the front beam 107 to rotate, while the extension and retraction of the side guard plate hydraulic rod 205 drives the side guard plate 108 to rotate, thus ensuring support. When energy storage is required, the controller 101 controls the air outlet valve 605 to open, thereby expelling the air from the air bladder 611 and filling the hydraulic accumulator 4 with hydraulic oil, facilitating the next round of energy release. At this time, the controller 101 controls the protective cover moving rod 601 to work in the opposite direction, so that the sealing ring 604 and the air inlet pipe 6 are tightly fitted, preventing air from entering and thus preventing coal dust from clogging the filter plate 606.
