[0085] The specific embodiments of the hydraulic hinge gate power source device are described below according to the structure of the hydraulic hinge gate power source device provided by the embodiments of the present application.

[0086] The application provides a hydraulic hinge gate power source device 100, which can be applied to a dam or the like, and is used in cooperation with a hydraulic hinge gate driving device 200. The hydraulic hinge gate driving device 200 can be a common hydraulic driving station, and can drive the dam to move. The hydraulic hinge gate power source device 100 is connected with the hydraulic hinge gate driving device 200 through a hydraulic pipeline, and can provide pressure energy to the hydraulic hinge gate driving device 200 under manual driving. The hydraulic hinge gate driving device 200 can convert the pressure energy into mechanical energy to drive the dam to open and close. In this way, under extreme conditions such as circuit damage and insufficient energy supply, the hydraulic hinge gate power source device 100 can be manually operated to drive the dam to open and close.

[0087] Please refer to Figure 1 and Figure 2 The hydraulic hinge gate power source device 100 comprises a first oil pump 1, a second oil pump 2, a first hand pump 3, a second hand pump 4 and a pipeline assembly 5. The first oil pump 1 comprises a first plunger 11 arranged in the first oil pump 1, and the first plunger 11 divides the first oil pump 1 into a first oil outlet chamber 12 and a first oil suction chamber 13. The second oil pump 2 comprises a second plunger 21 arranged in the second oil pump 2, and the second plunger 21 divides the second oil pump 2 into a second oil outlet chamber 22 and a second oil suction chamber 23. The first hand pump 3 is internally provided with a first hydraulic chamber 31, and the first hydraulic chamber 31 is movably provided with a first piston 32 that divides the first hydraulic chamber 31 into a first hydraulic upper chamber 311 and a first hydraulic lower chamber 312. The first piston 32 is in transmission connection with the first plunger 11. The second hand pump 4 is internally provided with a second hydraulic chamber 41, and the second hydraulic chamber 41 is movably provided with a second piston 42 that divides the second hydraulic chamber 41 into a second hydraulic upper chamber 411 and a second hydraulic lower chamber 412. The second piston 42 is in transmission connection with the second plunger 21. The pipeline assembly 5 comprises a first oil outlet pipe 51 and a first oil suction pipe 52. The first oil outlet pipe 51 communicates the first oil outlet chamber 12 and the second oil outlet chamber 22 with an oil inlet end of the hydraulic hinge gate driving device 200. The first oil suction pipe 52 communicates the first oil suction chamber 13 and the second oil suction chamber 23 with an oil outlet end of the hydraulic hinge gate driving device 200.

[0088] The first oil pump 1 and the second oil pump 2 can be common hydraulic oil pumps. The first hand pump 3 and the second hand pump 4 can be common jacks. Specifically, the first hand pump 3 and the second hand pump 4 can be one-way jacks driven by hand pressure rods.

[0089] The first oil outlet pipe 51 and the first oil suction pipe 52 in the pipeline assembly 5 can be common hydraulic pipes, which have certain strength and sealing performance, can withstand the pressure of the internal oil and prevent oil leakage. The first oil outlet pipe 51 and the first oil suction pipe 52 are provided to enable the oil to flow between the first oil pump 1, the second oil pump 2 and the hydraulic hinge gate driving device 200, thereby ensuring the normal operation of the hydraulic hinge gate power source device 100.

[0090] The first piston 32 is in transmission connection with the first plunger 11, including but not limited to direct connection, connecting rod connection, gear connection, etc. The first piston 32 can have a protruding portion protruding from the first hand pump 3. When the first hand pump 3 is pressed, the protruding portion of the first piston 32 is elongated outward and pushes the first plunger 11 to move. The second piston 42 also has a protruding portion protruding from the second hand pump 4. When the second hand pump 4 is pressed, the protruding portion of the second piston 42 is elongated outward and pushes the second plunger 21 to move.

[0091] Based on the above structure, the first hand pump 3 and the second hand pump 4 can be driven to move by manual work. The first piston 32 is in transmission connection with the first plunger 11, and the second piston 42 is in transmission connection with the second plunger 21. In this way, the first plunger 11 extrudes the oil in the first oil outlet chamber 12 to the oil inlet end of the hydraulic hinge gate driving device 200 to provide power for it, and the second plunger 21 extrudes the oil in the second oil outlet chamber 22 to the oil inlet end of the hydraulic hinge gate driving device 200 to provide power for it. The present scheme uses manual driving of the hydraulic hinge gate power source device 100, which can drive the hydraulic hinge gate driving device 200 when there is power failure or insufficient energy supply, so that the hydraulic movable dam can be quickly raised and lowered.

[0092] In one embodiment, the pipeline assembly 5 further includes a first communication pipe 53 and a second communication pipe 54. The first communication pipe 53 communicates the first hydraulic upper chamber 311 with the second hydraulic lower chamber 412, and the second communication pipe 54 communicates the first hydraulic lower chamber 312 with the second hydraulic upper chamber 411.

[0093] In order to facilitate operation, ensure that the first hand pump 3 and the second hand pump 4 are operated, any one of them can synchronously drive the first oil pump 1 and the second oil pump 2 to act, the embodiment is provided with a first communication pipe 53 and a second communication pipe 54, when only the first hand pump 3 is pressed, the first hydraulic upper cavity 311 is filled with oil, and based on the connection relationship of the first communication pipe 53, part of the oil in the first hydraulic upper cavity 311 will synchronously enter the second hydraulic lower cavity 412. Based on the increase of the oil pressure in the first hydraulic upper cavity 311 and the second hydraulic lower cavity 412, the first piston 32 and the second piston 42 will synchronously move, it should be noted that the first hand pump 3 and the second hand pump 4 can be arranged side by side, and the moving directions of the first piston 32 and the second piston 42 are the same. Similarly, when the second hand pump 4 is pressed, the first piston 32 and the second piston 42 will also synchronously move.

[0094] In one of the embodiments, the hydraulic hinge gate power source device 100 further comprises a third oil pump 6 and a fourth oil pump 7, the third oil pump 6 comprises a third plunger 61 arranged in the third oil pump 6, the third plunger 61 divides the third oil pump 6 into a third oil outlet cavity 62 and a third oil suction cavity 63, the fourth oil pump 7 comprises a fourth plunger 71 arranged in the fourth oil pump 7, the fourth plunger 71 divides the fourth oil pump 7 into a fourth oil outlet cavity 72 and a fourth oil suction cavity 73;

[0095] The two ends of the first piston 32 extend to the outside of the first hand pump 3, the two ends of the first piston 32 are connected with the first plunger 11 and the third plunger 61 respectively, the two ends of the second piston 42 extend to the outside of the second hand pump 4, the two ends of the second piston 42 are connected with the second plunger 21 and the fourth plunger 71 respectively;

[0096] The pipeline assembly 5 further comprises a second oil outlet pipe 55 and a second oil suction pipe 56, the second oil outlet pipe 55 connects the third oil outlet cavity 62 and the fourth oil outlet cavity 72 with the oil inlet end of the hydraulic hinge gate driving device 200, and the second oil suction pipe 56 connects the third oil suction cavity 63 and the fourth oil suction cavity 73 with the oil outlet end of the hydraulic hinge gate driving device 200.

[0097] Please refer to Figure 3 , the first hand pump 3 and the second hand pump 4 can be double-head jacks, so the two ends of the first piston 32 extend to the outside of the first hand pump 3, and the two ends of the second piston 42 extend to the outside of the second hand pump 4. Because the third oil pump 6 and the fourth oil pump 7 are added in the embodiment, combined with the above connection relationship, the first plunger 11 and the third plunger 61 will move simultaneously when the first hand pump 3 moves, and the second plunger 21 and the fourth plunger 71 will move simultaneously when the second hand pump 4 moves, in this way, the oil discharge capacity of the hydraulic hinge gate power source device 100 is increased, and the speed of the action of the hydraulic hinge gate driving device 200 and the opening and closing of the gate is further accelerated.

[0098] The following describes the operation of the hydraulic hinge gate power source device 100 in conjunction with the drawings:

[0099] Referring to Figure 3 , in the initial state, the first hand pump 3 and the second hand pump 4 are arranged side by side, and the directions in which the pistons inside them extend are the same when they are working, that is, when the first hand pump 3 is pressed, the first piston 32 moves to the right, and when the second hand pump 4 is pressed, the second piston 42 moves to the right.

[0100] The first hand pump 3 is reciprocally pressed, and the oil in the first hydraulic lower cavity 312 enters the first hydraulic upper cavity 311 through the one-way valve, and the oil in the first hydraulic upper cavity 311 increases, at the same time, part of the oil in the first hydraulic upper cavity 311 enters the second hydraulic lower cavity 412 through the first communication pipe 53, and as the oil in the first hydraulic upper cavity 311 and the second hydraulic lower cavity 412 increases, the first piston 32 moves to the right, and the second piston 42 moves to the left.

[0101] The right end of the first piston 32 pushes the first plunger 11 to move to the right, so that the high-pressure oil in the first oil outlet cavity 12 enters the oil inlet end of the hydraulic hinge gate driving device 200 through the first oil outlet pipe 51; the left end of the first piston 32 pulls the third plunger 61 to move to the right, and the third oil suction cavity 63 of the third oil pump 6 forms a negative pressure and sucks oil from the oil outlet end of the hydraulic hinge gate driving device 200 through the first oil suction pipe 52.

[0102] Based on similar principles, the left end of the second piston 42 pushes the second plunger 21 to move to the left, so that the high-pressure oil in the second oil outlet cavity 22 enters the oil inlet end of the hydraulic hinge gate driving device 200 through the first oil outlet pipe 51, it should be noted that the first oil outlet pipe 51 here can be combined with the first oil outlet pipe 51 described above to form a three-way pipe structure, of course, two separate first oil outlet pipes 51 can also be used to communicate with the oil inlet end of the hydraulic hinge gate driving device 200. The right end of the second piston 42 pulls the fourth plunger 71 to move to the left, so that the fourth oil suction cavity 73 of the fourth oil pump 7 forms a negative pressure and sucks oil from the oil outlet end of the hydraulic hinge gate driving device 200 through the first oil suction pipe 52. It can be understood that the first oil suction pipe 52 here can be combined with the first oil suction pipe 52 described above to form a three-way pipe structure, or two separate first oil suction pipes 52 can be used.

[0103] When the first piston 32 moves to the right to the limit distance, the second hydraulic hand pump 4 can be started to reciprocate, the oil in the second hydraulic lower cavity 412 flows into the second hydraulic upper cavity 411 through the one-way valve, the oil in the second hydraulic upper cavity 411 increases, at the same time, part of the oil in the second hydraulic upper cavity 411 flows into the first hydraulic lower cavity 312 through the second communication pipe 54, with the increase of the oil in the second hydraulic upper cavity 411 and the first hydraulic lower cavity 312, the first piston 32 moves to the left and the second piston 42 moves to the right.

[0104] The right end of the second piston 42 pushes the fourth plunger 71 to move to the right, so that the high-pressure oil in the fourth oil outlet cavity 72 flows into the oil inlet end of the hydraulic hinge brake driving device 200 through the second oil outlet pipe 55; the left end of the second piston 42 pulls the second plunger 21 to move to the right, the second oil pump 2 forms negative pressure in the second oil suction cavity 23 and sucks oil from the oil outlet end of the hydraulic hinge brake driving device 200 through the second oil suction pipe 56.

[0105] Based on similar principles, the left end of the first piston 32 pushes the third plunger 61 to move to the left, so that the high-pressure oil in the third oil outlet cavity 62 flows into the oil inlet end of the hydraulic hinge brake driving device 200 through the first oil outlet pipe 51, and the right end of the first piston 32 pulls the first plunger 11 to move to the left, so that the first oil suction cavity 13 forms negative pressure and sucks oil from the oil outlet end of the hydraulic hinge brake driving device 200 through the first oil suction pipe 52.

[0106] It can be understood that the second oil outlet pipe 55 and the second oil suction pipe 56 herein can be a three-way pipe structure, so that the second oil outlet pipe 55 can guide the oil in the second oil outlet cavity 22 and the fourth oil outlet cavity 72 into the oil inlet end of the hydraulic hinge brake driving device 200, and the second oil suction pipe 56 can suck the oil from the oil outlet end of the hydraulic hinge brake driving device 200 back into the second oil outlet cavity 22 and the fourth oil outlet cavity 72.

[0107] It should be noted that one-way valves can be arranged in the above-mentioned pipe assembly 5 to strictly control the flow direction of the oil, thereby ensuring the normal operation of the hydraulic hinge brake power source device 100.

[0108] In one embodiment, the hydraulic hinge brake power source device 100 further comprises a first multiplying device 8 and a second multiplying device 9, the first multiplying device 8 comprises a first fixed rack 81, a first movable rack 82 and a first gear 83, the first fixed rack 81 is fixedly arranged relative to the first hydraulic hand pump 3, the first movable rack 82 is movably arranged relative to the first hydraulic hand pump 3, the two ends of the first movable rack 82 are connected with the first plunger 11 and the third plunger 61 respectively, the end of the first plunger 11 is hingedly provided with the first gear 83, the first fixed rack 81 and the first movable rack 82 are oppositely arranged and are both meshingly connected with the first gear 83.

[0109] The second multiplying device 9 comprises a second fixed rack 91, a second movable rack 92 and a second gear 93. The second fixed rack 91 is fixedly arranged relative to the second hand pump 4. The second movable rack 92 is movably arranged relative to the second hand pump 4. The two ends of the second movable rack 92 are connected with the second plunger 21 and the fourth plunger 71 respectively. The end of the second plunger 21 is hingedly provided with the second gear 93. The second fixed rack 91 is oppositely arranged relative to the second movable rack 92 and is in meshing connection with the second gear 93.

[0110] Please refer to Figure 4 and Figure 5 The first multiplying device 8 and the second multiplying device 9 can multiply the displacement output by the first hand pump 3 and the second hand pump 4. Taking the first multiplying device 8 as an example, the two ends of the first plunger 11 are hingedly provided with the first gear 83. Since the first fixed rack 81 is fixedly arranged relative to the first hand pump 3, the first gear 83 at the end of the first plunger 11 will synchronously drive the first movable rack 82 to move when the first gear 83 rolls on the first fixed rack 81. When the first plunger 11 moves by a distance X, the first movable rack 82 moves by a distance 2X, because the first movable rack 82 is synchronously driven to move when the first plunger 11 moves the tooth part of the first movable gear. The structure and distance of the second multiplying device 9 are similar to those of the first multiplying device 8, which will not be described here.

[0111] Through the above arrangement, the action distance of the first hand pump 3 and the second hand pump 4 is multiplied, and the oil output of each oil pump is significantly improved, thereby improving the use efficiency of the hydraulic hinge brake power source device 100.

[0112] In one embodiment, the first multiplying device 8 further comprises a first guide assembly 84. The first guide assembly 84 comprises a first guide rod 85 and a first guide wheel 86 hingedly arranged on the first guide rod 85. The first guide wheel 86 abuts against one side of the first movable rack 82 away from the first fixed rack 81. One end of the first guide rod 85 away from the first guide wheel 86 is connected with the first fixed rack 81. In one embodiment, the first guide wheel 86 is an elastic rubber wheel.

[0113] In one embodiment, the second multiplying device 9 further comprises a second guide assembly 94. The second guide assembly 94 comprises a second guide rod 95 and a second guide wheel 96 hingedly arranged on the second guide rod 95.
