[0002] A hydraulic coupling is a device that uses the principles of liquid dynamics to achieve power transmission. It is widely used in automobiles, construction machinery and industrial equipment. It consists of a pump and a turbine. The pump is connected to the engine output shaft, and the turbine is connected to the load equipment. When the engine is running, the pump rotates and throws the engine oil (or other liquids) to the turbine, causing the turbine to rotate as well, thereby achieving power transmission. This coupling method has smooth starting and speed change characteristics, can effectively absorb impact loads, reduce mechanical wear, and improve the efficiency and reliability of the transmission system. The hydraulic coupling also has a gliding function to a certain extent, which enables it to adjust the speed when the load changes to maintain balance and stability.

[0003] However, the oil inside the hydraulic coupling will become dirty due to various factors during use, mainly due to impurities such as metal particles and rubber crumbs generated by wear, and dust and dirt from the external environment penetrating through the seals. Long-term use will cause oil aging and performance degradation, reducing the service life of the hydraulic coupling. For this reason, a hydraulic coupling for an electric power energy system is proposed. Utility Model Content

[0029] The following will be combined with the attached Figures 1 to 5 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model provides a hydraulic coupler for an electric power system through improvement. Figure 1 - Figure 5 As shown, it includes a hydraulic coupling body 1, a coupler 102 is arranged inside the hydraulic coupling body 1, and the left and right ends of the coupler 102 are respectively fixedly connected with a driven shaft 103 and a driving shaft 104 which are rotatably connected to the side wall of the fixed shell 101, and a power storage component 2 for driving is installed on the driven shaft 103;

[0031] The power storage assembly 2 includes a first gear 201 fixedly connected to the driven shaft 103, and the fixed housing 101 is rotatably connected to a second gear 202 meshing with the first gear 201 through a vertical plate fixedly connected to the inner wall of the upper side of the fixed housing 101. Figure 2 As shown, a rotating drum 203 is arranged on one side of the second gear 202, a top drum 204 is slidably connected inside the rotating drum 203, a return spring 205 is fixedly connected between the top drum 204 and the rotating drum 203, a threaded groove 207 is cut on the inner wall of the top drum 204, a guide rod 208 fixedly connected to the rotating shaft 206 is slidably connected inside the threaded groove 207, a locking assembly 3 for limiting the rotation of the rotating drum 203 is arranged on the power storage assembly 2, the second gear 202 in the power storage assembly 2 is fixedly connected to a filtering assembly 6 for filtering through a first belt group 4, and The filter assembly 6 is communicated with the coupler 102, and the filter assembly 6 is connected to the infusion assembly 5 for driving the flow of oil through the second belt group 7. The locking assembly 3 includes a concave plate 302 fixedly connected to the fixed shell 101 through two fixed plates 301, a square rod 303 is inserted into one end of the rotating cylinder 203, and a convex plate 304 is fixedly connected to the end of the square rod 303 away from the rotating cylinder 203. The inner side wall of the fixed shell 101 is fixedly connected to a thrust spring 306, and one end of the thrust spring 306 is fixedly connected to a disc 305 rotatably connected to the convex plate 304.

[0032] It is worth noting that a one-way bearing is fixedly connected between the second gear 202 and the first belt set 4, so that when the driving shaft 104 rotates, the rotation direction of the driven shaft 103 cannot drive the first belt set 4 to rotate. Only when the driven shaft 103 reverses can the transmission purpose be achieved through the first belt set 4.

[0033] In this embodiment: the first gear 201 is driven to rotate by the driven shaft 103, and the first gear 201 drives the rotating shaft 206 to rotate by meshing with the second gear 202. Since the rotating cylinder 203 and the top cylinder 204 are slidably connected by the sliding groove clamping mode, and the rotation of the rotating cylinder 203 is restricted by the locking component 3 and cannot rotate, the rotating shaft 206 can drive the top cylinder 204 to move through the cooperation of the guide rod 208 and the thread groove 207. When the top cylinder 204 moves, the reset spring 205 is compressed to achieve the purpose of storing kinetic energy, until the top cylinder 204 pushes the locking component 3, at which time the rotating cylinder 203 is completely released, and the rotating cylinder 203 rotates;

[0034] In the initial state, the convex disc 304 is pushed by the thrust spring 306 and fits tightly with the concave disc 302. At this time, the convex disc 304 restricts the rotating drum 203 through the square rod 303, so that the rotating drum 203 cannot rotate. When the top cylinder 204 pushes the square rod 303, the square rod 303 drives the convex disc 304 to separate from the concave disc 302. At this time, the convex disc 304 is in an active state. At this time, the rotation of the driven shaft 103 can be rotated as a whole through the power storage component 2. When the driven shaft 103 stops rotating, the top cylinder 204 is reset under the elastic force of the reset spring 205. At the same time, the reset spring 205 relies on the threaded groove 207 to drive the rotating shaft 206 and the second gear 202 to rotate.

[0035] In the above embodiment, in order to enable the oil inside the coupler 102 to flow, the following method can be adopted: the infusion component 5 includes an oil cylinder 501 fixedly connected to the inner wall of the lower side of the fixed shell 101, and a movable plug 502 is slidably connected inside the oil cylinder 501. Two support plates 503 are fixedly connected at both ends of the oil cylinder 501, and a magnet block 504 magnetically connected to the movable plug 502 is rotatably connected between the two support plates 503.

[0036] In a preferred embodiment, when the second gear 202 rotates, the valve core 603 and the filter element 604 are driven to rotate 180 degrees through the first belt group 4, and the valve core 603 drives the magnet block 504 to rotate 180 degrees through the second belt group 7, so that the magnet block 504 attracts the movable plug 502 to move, and when the movable plug 502 moves, the oil passes through one of the transmission pipes 601 and the filter element 604 connected thereto and is filtered, and then enters the coupler 102, and the other end of the oil cylinder 501 sucks the oil inside the coupler 102 through the transmission pipe 601, thereby filtering and replacing the oil inside the coupler 102.

[0037] refer to Figure 4 and Figure 5 In a preferred embodiment, the filter assembly 6 includes a valve housing 602 connected to the oil cylinder 501 through a transmission pipe 601, and the valve housing 602 is connected to the coupler 102. A valve core 603 fixedly connected to the first belt group 4 is rotatably connected inside the valve housing 602. The rotating shaft of the valve core 603 passes through the valve housing 602 and is fixedly connected to the first belt group 4. When the second gear 202 rotates, the valve core 603 can be driven to rotate together through the first belt group 4. A filter element 604 is fixedly connected inside the valve core 603. A second belt group 7 is fixedly connected between the filter element 604 and the magnet block 504. The rotating rod of the magnet block 504 passes through the support plate 503 and is fixedly connected to the second belt group 7. When the valve core 603 rotates, the magnet block 504 is also driven to rotate through the second belt group 7.

[0038] It is worth noting that each time the top cylinder 204 travels a full distance, the second gear 202 can only rotate the electric valve core 603 180 degrees through the first belt group 4, and every time the valve core 603 rotates 180 degrees, the magnet block 504 can be driven to rotate 180 degrees through the second belt group 7.

[0039] In this embodiment, the filter element 604 is rotated 180 degrees so that only one end of the filter element 604 can be used to filter the oil, further improving the filtering effect.

[0040] Working principle: When in use, the driving device drives the active shaft 104 to rotate, the active shaft 104 drives the driven shaft 103 to rotate through the coupler 102, the driven shaft 103 drives the rotating shaft 206 to rotate through the meshing of the first gear 201 and the second gear 202, the rotating shaft 206 drives the top cylinder 204 to move through the guide rod 208, which compresses the reset spring 205 until the top cylinder 204 pushes the square rod 303 of the locking assembly 3, at which time the rotating cylinder 203 is released and the rotating cylinder 203 rotates;

[0041] The convex disc 304 is no longer tightly fitted with the concave disc 302 as in the initial state. At this time, the convex disc 304 is in a movable state, so that the rotation of the driven shaft 103 drives the power storage assembly 2 to rotate as a whole. When the driven shaft 103 stops rotating, the top cylinder 204 is reset under the elastic force of the reset spring 205. At the same time, the reset spring 205 drives the rotating shaft 206 and the second gear 202 to reverse by relying on the thread groove 207.

[0042] When the second gear 202 is reversed, the first belt group 4 can be driven to transmit through the one-way bearing, and the first belt group 4 drives the valve core 603 to rotate 180 degrees. The valve core 603 drives the magnet block 504 to rotate 180 degrees through the second belt group 7, so that the magnet block 504 sucks the movable plug 502 to move. When the movable plug 502 moves, the oil passes through one of the transmission pipes 601 and the filter element 604 connected thereto and is filtered, and then enters the coupler 102. At the other end of the oil cylinder 501, the magnet block 504 and the movable plug 502 repel each other, so that the oil cylinder 501 sucks the oil inside the coupler 102 through the transmission pipe 601, so as to filter and replace the oil inside the coupler 102.

[0043] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
