[0021] Beneficial effects:

[0022] 1. This invention uses a drive motor to drive a transmission wheel, which in turn drives a cylindrical rod to move the strip frame on the piston rod away from the connecting tee, thus increasing the volume of the piston and drawing water from the external water tank. Conversely, the strip frame on the piston rod moves towards the connecting tee, thus decreasing the volume of the piston and sending water through the hydraulic actuator channel into the main body's circulating water circuit.

[0024] 3. This invention provides power-assisted heat dissipation through water circulation. The water drives the impeller to rotate, which in turn drives the exhaust fan to rotate and generate suction. Outside air passes through the dustproof cotton strip into the top cover, then through the exhaust fan and the mounting frame into the external water tank, and blows the water circulating to the heat dissipation stepped plate to dissipate heat from the water, reduce the water temperature, and ensure that the water can circulate continuously.

[0042] Example 1:

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, Figure 1 A three-dimensional structural schematic diagram of the water-cooled self-circulating device in an embodiment of the present invention is shown; Reference Figure 1 A self-circulating water-cooled condenser device includes a main body 1, a hydraulic actuator 3, a liquid pumping mechanism 5, a drive mechanism, and an external water tank 9. The main body 1 has an internal circulating water circuit, and the external water tank 9 is located outside the main body 1. The hydraulic actuator 3, the liquid pumping mechanism 5, and the drive mechanism are arranged between the external water tank 9 and the main body 1 (see reference). Figure 3 The outlet of the external water tank 9 is connected in sequence to the pumping mechanism 5, the hydraulic actuator 3, and the inlet of the circulating water circuit via pipes; the outlet of the circulating water circuit is connected to the external water tank 9; the drive mechanism is installed on the pumping mechanism 5, and the drive mechanism drives the pumping mechanism 5 to circulate water in the external water tank 9 and the circulating water circuit. The main body 1 is the main body 1 of the camera condenser. A circulating water circuit is set inside the main body 1. The outlet and inlet of the circulating water circuit are located on the side of the main body 1 near the external water tank 9; the inlet of the external water tank 9 on the side near the main body 1 is connected to the outlet of the circulating water circuit.

[0045] In the implementation of this invention, reference is made to Figure 7 and Figure 8 The hydraulic actuator 3 includes a channel 301, a protruding seat 302, an impeller 303, an exhaust fan 304, and a frame 305. The frame 305 is installed in a ventilation groove on the side of the main body 1. The channel 301 is provided on the frame 305. The exhaust fan 304 is rotatably installed in the middle position of the frame 305. The impeller 303 is coaxially connected to the exhaust fan 304 and is installed inside the channel 301. The channel 301 has a section of arc-shaped channel, and the impeller 303 is installed in the arc-shaped channel to facilitate water flow impact on the impeller 303. The inlet of the channel 301 is connected to the liquid extraction mechanism 5, and the outlet of the channel 301 is connected to the inlet of the circulating water circuit. The hydraulic actuator 3 also includes a waterproof bearing. The outer ring of the waterproof bearing is sealed to the channel 301, and the inner ring is sealed to the shaft of the impeller 303 (e.g., Figure 9 (As shown).

[0046] Specifically, the hydraulic actuator 3 has a square frame structure, with a channel 301 integrally provided in the middle of the frame 305; two sets of protruding seats 302 are integrally provided at both ends of the rear side of the frame 305, and an assembly frame 4 is fixedly provided on the outside of the protruding seats 302.

It can be powered by water circulation. The water drives the impeller 303 to rotate, which in turn drives the exhaust fan 304 to rotate and generate suction. Outside air passes through the dustproof cotton strip 201 and enters the top cover 2, which cools the main body 1. The air then passes through the exhaust fan 304 and the assembly frame 4 and enters the external water tank 9, blowing the water circulating to the heat dissipation stepped plate 902 to dissipate heat from the water, reduce the water temperature, and ensure that the water can circulate continuously.

[0047] like Figure 4 As shown, Figure 4 A schematic diagram showing the installation positions of the liquid extraction mechanism, U-shaped frame, transmission wheel, and drive motor in Embodiment 1 of the present invention is shown; see reference. Figure 4 The liquid extraction mechanism 5 includes a first one-way valve 501, a connecting tee 502, a piston 503, a strip frame 504, a first connecting water tank 505, and a second connecting water tank 506. The first connecting water tank 505 is connected to the channel 301 via a pipe, and the second connecting water tank 506 is connected to the external water tank 9 via a pipe. The first connecting water tank 505 is equipped with the first one-way valve 501, and the second connecting water tank 506 is equipped with the second one-way valve 507. Two of the connecting tee 502's ports are connected to the first one-way valve 501 and the second one-way valve 507, respectively, and the third port of the connecting tee 502 is connected to the piston 503. The piston rod of the piston 503 is connected to the strip frame 504, and the strip frame 504 is connected to the drive mechanism.

[0048] In a preferred embodiment, two first connecting water tanks 505 are installed outside two second connecting water tanks 506; two sets of first one-way valves 501 are fixedly installed on the top of both the two first connecting water tanks 505 and the two second connecting water tanks 506, the first one-way valves 501 above the first connecting water tanks 505 restrict the liquid to flow downwards, and the first one-way valves 501 above the two sets of second connecting water tanks 506 restrict the liquid to flow upwards; a connecting tee 502 is fixedly installed above the adjacent first connecting water tanks 505 and second connecting water tanks 506, and each set of connecting tee 502 forms a circulation structure with the adjacent first connecting water tanks 505 and second connecting water tanks 506; a protruding seat 302 is fixedly connected to the bottom of the first connecting water tank 505 near the hydraulic actuator 3 and communicates with the inlet of the channel 301, and a pipe is provided outside the other end of the protruding seat 302 to connect to the inlet of the circulating water circuit inside the main body 1; a tee is provided at the bottom of the two sets of liquid pumping mechanisms 5 to connect to the lower front end of the external water tank 9.

[0049] In accordance with the embodiments of the present invention, the main body of the connecting tee 502 is a trapezoidal structure. A piston component 503 is fixedly installed at the top of each connecting tee 502. The piston component 503 includes a cavity and a piston rod. The piston rod is slidably installed in the cavity, which is connected and circumvents the connecting tee 502. Two sets of strip frames 504 are fixedly installed at the telescopic ends of the front and rear piston components 503. The piston component 503 provides a water-cooling function, enabling continuous cooling of the main body 1. The transmission wheel 7 drives the cylindrical rods 701, respectively mounted on the first wheel 702 and the second wheel 703, to rotate. The two cylindrical rods 701 are positioned opposite each other; that is, when one cylindrical rod 701 is at the top of the first wheel 702, the other cylindrical rod 701 is at the bottom of the second wheel 703. When the two cylindrical rods 701 drive the two strip frames 504 to reciprocate, one drives the strip frame 504... The piston 503 connected to the strip frame 504 extends upwards, expanding the cavity. Meanwhile, the piston 503 connected to the strip frame 504 moves downwards, compressing the cavity. This reciprocating motion causes the pistons on the front and rear sides to expand and shrink the cavity in sequence, drawing water from the external water tank 9 into the circulating water circuit of the main body 1. This continuously cools the main body 1, significantly improving cooling efficiency and ensuring a good cooling effect.

[0050] According to the embodiments of the present invention, the driving mechanism includes a transmission wheel 7 and a drive motor 8. The drive motor 8 is fixedly installed on the outside of the main body 1, and the transmission wheel 7 is rotatably installed on a U-shaped frame 6. The U-shaped frame 6 is fixedly installed on the outside of the main body 1 and is located on the side of the drive motor 8 closer to the liquid extraction mechanism 5. The transmission wheel 7 is drivenly connected to the liquid extraction mechanism 5, that is, a cylindrical rod 701 is provided on the outside of the transmission wheel 7. The cylindrical rod 701 is slidably installed in the strip frame 504, and the drive motor 8 is drivenly connected to the transmission wheel 7. The transmission wheel 7 is rotatably arranged on both sides of the U-shaped frame 6. The transmission wheel 7 is composed of two sets of wheel disks with a connecting shaft in the middle. The connecting shaft rotates in the U-shaped frame 6. A cylindrical rod 701 is fixedly arranged on the outside of both wheel disks. The cylindrical rods 701 on both sides are in opposite positions and slide in a set of strip frames 504. Specifically, the transmission wheel 7 includes a first wheel disc 702 and a second wheel disc 703, which are respectively disposed on both sides of the U-shaped frame 6 and fixedly connected by a shaft; a gear ring is provided on the edge of the second wheel disc 703 near the first wheel disc 702, and the gear ring meshes with a bevel gear provided on the shaft end of the drive motor 8; a cylindrical rod 701 is provided on the opposite side of the first wheel disc 702 and the second wheel disc 703 away from the center, and the cylindrical rod 701 is slidably installed in the strip frame 504. (See reference in the present invention) Figure 6An external water tank 9 has a water level sensor 901 located at the inner corner of its interior, and a water control pipe 904 located on the outside of the external water tank 9. An electronic gate valve 903 is installed on the water control pipe 904. The water level sensor 901 is electrically connected to the electronic gate valve 903. The external water tank 9 provides intelligent auxiliary heat dissipation. The water level sensor 901 monitors the water level. When the water level decreases due to evaporation, the electronic gate valve 903 is intelligently opened through the program, and a water pump is used to replenish the water and maintain water circulation. When the overall temperature rises due to prolonged water circulation, two-thirds of the water in the external water tank 9 can be extracted through the control program and replaced with cold water to lower the water temperature and provide cooling for the main unit 1.

[0051] In a specific embodiment, a heat dissipation stepped plate 902 is installed inside the external water tank 9, and the heat dissipation stepped plate 902 is located below the outlet of the circulating water path. The main body of the external water tank 9 is a sloping water tank structure with a higher front and lower back; a water level sensor 901 for monitoring the water level is fixedly installed on the rear of the right inner wall of the external water tank 9; a heat dissipation stepped plate 902 extending backward is fixedly installed on the upper middle front side of the external water tank 9, and all heat dissipation stepped plates 902 have an inclined structure with a higher front and lower back; the uppermost heat dissipation stepped plate 902 is higher on both sides and lower in the middle; an electronic gate valve 903 is connected to the left side of the external water tank 9, and a water control pipeline 904 is connected to the outside of the electronic gate valve 903; a water pump and a water tank are connected to the outside of the water control pipeline 904 for supplying water.

[0052] In the above embodiments, another optional implementation is as follows: a stator cover 101 with ventilation holes is provided on the upper surface of the main body 1; a top cover 2 is provided on the stator cover 101; a groove is provided on the top cover 2; and a dustproof cotton strip 201 is installed on the groove. Specifically, the dustproof cotton strip 201 is used to prevent dust from entering the main body 1. An assembly frame 4 is also included, which is installed between the main body 1 and the external water tank 9. The assembly frame 4 is hollow, with one end aligned with the hydraulic actuator 3 and the other end facing the heat dissipation stepped plate 902. The assembly frame 4 acts as a pipe, blowing the air blown by the impeller 303 onto the heat dissipation stepped plate 902 to cool the water on the heat dissipation stepped plate 902. Simultaneously, the assembly frame 4 protects the hydraulic actuator 3. Two sets of round holes are provided on the front side of the external water tank 9, which are fitted, aligned, and sealed with the assembly frame 4.

[0053] Working principle:

[0054] The water level is monitored by the water level sensor 901. When the water level falls below the limit, the electronic gate valve 903 automatically opens to replenish water and keep the water level within a stable range.

[0055] The drive motor 8 is started, causing the second wheel 703 and the first wheel 702 to rotate. The second wheel 703 and the first wheel 702 then rotate the cylindrical rod 701, which in turn drives the strip frame 504 to reciprocate. The transmission wheel 7 drives the cylindrical rods 701, which are respectively mounted on the first wheel 702 and the second wheel 703, to rotate. The two cylindrical rods 701 are positioned opposite each other; that is, when one cylindrical rod 701 is at the top of the first wheel 702, the other cylindrical rod 701 is at the bottom of the second wheel 703. When the two cylindrical rods 701 drive the two strip frames 504 to reciprocate, one rod moves the strip frame 504 upwards, thereby moving the strip frame 504 connected to it. As piston 503 extends, the cavity expands. This causes another piston 504 to move downward, which in turn compresses the cavity of piston 503 connected to the frame 504. This reciprocating motion causes the pistons on the front and rear sides to expand and contract in sequence. Water passes through the second connecting water tank 506 in the middle, enters the second one-way valve 507, and then enters the connecting tee 502 and piston 503. It then passes through the first one-way valve 501, enters the first connecting water tank 505 on the side, enters the channel 301, and then enters the circulating water circuit of the main body 1 to continuously cool the main body 1. Finally, the water enters the external water tank 9 and flows downward continuously following the stepped guide of the heat dissipation stepped plate 902.

[0056] During this process, the water drives the impeller 303 to rotate, which in turn drives the exhaust fan 304 to rotate and generate suction. Outside air passes through the dustproof cotton strip 201, enters the top cover 2, and then enters the main body 1. It then passes through the exhaust fan 304 and the mounting frame 4 into the external water tank 9, and blows the water circulating to the heat dissipation step plate 902 to dissipate heat, lower the water temperature, and ensure that the water can circulate continuously.

[0057] Example 2:

[0058] Based on Example 1, the water level is monitored by a water level sensor 901. When the water evaporates and decreases, the electronic gate valve 903 is opened intelligently by the program, and the water pump is used to replenish the water and maintain the water circulation.

[0059] Example 3:

[0060] Based on Example 1, the water control pipeline 904 is connected to a bidirectional water pump, which is externally connected to an external water tank to provide backup water. When the overall temperature rises due to prolonged water circulation, two-thirds of the water in the external water tank 9 can be extracted through the control program and then filled with cold water to lower the water temperature and provide cooling for the main body 1 again. The specific usage and function of this embodiment: In this invention, during use, the water level is monitored by the water level sensor 901. After the water level is limited, the electronic gate valve 903 automatically opens to replenish water, keeping the water level within a stable range. The drive motor 8 is started to drive the transmission wheel 7 to rotate. The transmission wheel 7 drives the cylindrical rods 701 respectively set on the first wheel 702 and the second wheel 703 to rotate, and the two cylindrical rods 701 are positioned opposite each other. That is, when one cylindrical rod 701 is at the uppermost end of the first wheel 702, the other cylindrical rod 701 is at the lowermost end of the second wheel 703. When the two cylindrical rods 701 drive the two strip frames 504 to reciprocate, one drives the strip frame 504 to move upward, thereby causing the piston 503 connected to the strip frame 504 to extend and expand the cavity. The other drives the strip frame 504 to move downward, thereby causing the piston 503 connected to the strip frame 504 to extend and expand the cavity. The piston 503 connected to the frame 504 is compressed in the cavity. The reciprocating motion causes the pistons on the front and rear sides to expand and shrink in sequence. Water passes through the first one-way valve 501 in the middle and enters the connection between the three-way valve 502 and the piston 503. It then passes through the first one-way valve 501 on the side and enters the channel 301. It then enters the circulating water circuit of the main body 1 to continuously cool the main body 1. Finally, the water enters the external water tank 9 and flows downward along the stepped guide of the heat dissipation stepped plate 902. During this process, the water drives the impeller 303 to rotate, which in turn drives the exhaust fan 304 to rotate and generate suction. Outside air passes through the dustproof cotton strip 201 and enters the top cover 2. It then passes through the exhaust fan 304 and the mounting bracket 4 and enters the external water tank 9. It blows the water circulating to the heat dissipation stepped plate 902 to dissipate heat, lower the water temperature, and ensure that the water can circulate continuously.

[0061] The water level is monitored by the water level sensor 901. When the water evaporates and decreases, the electronic gate valve 903 is opened intelligently by the program, and the water pump is used to replenish the water and maintain the water circulation. When the water circulation for a long time causes the overall temperature to rise, two-thirds of the water in the external water tank 9 can be extracted by the control program and then cold water can be added to lower the water temperature and provide cooling function for the main body 1 again.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
