[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. After the cooling water stored in the water storage cylinder is transferred to the inside of the circulation shell, the circulation cooling mechanism and the inside of the circulation shell are switched and connected, so that the cooling water stored in the water storage cylinder is always cooled and cooled, and when it is transferred from the inside of the water storage cylinder to the inside of the circulation shell, it can directly quickly exchange heat with the lubricating oil in the second connecting pipe, thereby reducing the temperature of the lubricating oil flowing back to the lubrication station body, improving the cooling efficiency of the oil temperature and the real-time lubrication effect.

[0016] 2. The semicircular baffle is driven to rotate by the output shaft of the first motor, so that the semicircular baffle gradually reduces the obstruction of the fan-shaped groove at the connecting position of the first U-shaped tube, and correspondingly increases the obstruction of the fan-shaped groove at the connecting position of the guide tube, so that the part of the cooling water that has not been dissipated in the annular shell enters the first U-shaped tube along the corresponding semicircular shell, and is mixed with the cooling water after the heat is dissipated at the other end of the first U-shaped tube, and is then synchronously transported to the inside of the circulation shell, so that the temperature of the cooling water is increased after the addition and mixing of the cooling water that has not been dissipated in the semicircular shell, thereby preventing the lubricating oil in the second connecting tube from continuously cooling and falling below the lowest point, ensuring the use effect of the lubricating oil, and adjusting the addition ratio of the cooling water that has not been cooled by the rotation of the semicircular baffle.

[0017] 3. When the cooling water inside the water storage cylinder is transported to the inside of the circulation shell through the movement of the piston, the third L-shaped tube rises by cooperating with the lifting mechanism, thereby releasing the connection between the first mounting tube and the first L-shaped tube, and after the piston moves into the inside of the water storage cylinder, it blocks the connection between the first L-shaped tube and the water storage cylinder, allowing the cooling water to circulate unidirectionally along the inside of the circulation shell, thereby converting the circulation connection.

[0028] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0029] like Figures 1 to 9 The automatic circulating water cooling device for a lubrication station shown in the figure includes a lubrication station body 1 and an elevator reduction gearbox 2. A first connecting pipe 3 is fixedly connected between the oil outlet of the lubrication station body 1 and the oil inlet of the elevator reduction gearbox 2. A second connecting pipe 4 is fixedly connected between the oil inlet of the lubrication station body 1 and the oil outlet of the elevator reduction gearbox 2. An electric contact thermometer 5 is fixedly installed at one end of the second connecting pipe 4 near the lubrication station body 1.

[0030] A circulation shell 6 is fixedly connected to the second connecting pipe 4, and the two ends of the circulation shell 6 are fixedly connected to the first mounting pipe 7 and the second mounting pipe 8, respectively. One end of the first mounting pipe 7 and the second mounting pipe 8 are fixedly connected to the first U-shaped pipe 9 and the second U-shaped pipe 10, respectively. A circulation cooling mechanism and a temperature control adjustment mechanism are connected between the first U-shaped pipe 9 and the second U-shaped pipe 10. A water storage cylinder 11 is fixedly connected to the bottom of the circulation shell 6, and a first L-shaped pipe 12 (such as Figure 3 and Figure 5As shown), a second L-shaped tube 13 is fixedly connected between the water storage cylinder 11 and the second U-shaped tube 10, and the first L-shaped tube 12 is located at one end of the water storage cylinder 11 close to the first mounting tube 7. A water storage transfer mechanism is connected to the water storage cylinder 11, and a connection conversion mechanism is connected between the circulation shell 6 and the water storage cylinder 11. During operation, when cooling the lubricating oil inside the lubrication station, the prior art usually uses a thermometer to monitor the oil temperature in real time, and performs circulating water cooling when the oil temperature is higher than the upper limit point. However, it takes a certain amount of working time from the start of the cooling equipment to the start of heat exchange cooling of the oil temperature, thereby reducing the cooling efficiency of the lubricating oil and affecting the real-time lubrication effect of the lubricating oil. The oil supply temperature of the lubrication station has two limits, namely, the highest and the lowest. When the oil temperature is lower than the lowest value, the lubricating effect of the lubricating oil is reduced. It is difficult for the existing cooling equipment to return to the temperature when the temperature is lower than a certain level.The present technical solution can solve the above problems. The specific working method is as follows: the lubricating oil inside the lubrication station body 1 flows along the first connecting pipe 3 into the interior of the elevator reduction box 2, and then returns to the interior of the lubrication station body 1 along the second connecting pipe 4, thereby circulating and lubricating the interior of the elevator reduction box 2. When the internal components of the elevator reduction box 2 are working and cause the temperature of the lubricating oil to rise, the lubricating oil with increased oil temperature flows back to the lubrication station body 1 along the second connecting pipe 4. The temperature of the lubricating oil flowing inside the second connecting pipe 4 is monitored in real time by the electric contact thermometer 5, and the temperature of the lubricating oil flowing in the second connecting pipe 4 is monitored by the electric contact thermometer 5. When the high oil temperature and minimum temperature alarms are triggered and the oil temperature inside the second connecting pipe 4 exceeds the highest point, the cooling water stored in the water storage cylinder 11 is transferred to the inside of the circulation shell 6 and submerged in the second connecting pipe 4 through the action of the water storage transfer mechanism. The cooling water inside the circulation shell 6 flows along the inside of the circulation shell 6 toward the second mounting pipe 8 through the action of the circulation cooling mechanism, thereby flowing in the opposite direction to the lubricating oil inside the second connecting pipe 4, and heat is exchanged with the lubricating oil inside the second connecting pipe 4 during the contact process with the second connecting pipe 4, and enters the second U-shaped pipe 10, and then enters the first mounting pipe 7 along the first U-shaped pipe 9. The cooling water inside the water storage cylinder 11 is connected to the cooling water inside the water storage cylinder 11 and dissipates heat. When the cooling water is stored in the water storage cylinder 11, the cooling water inside the water storage cylinder 11 is connected to the cooling water circulation system 11 and dissipates heat. When the cooling water stored in the water storage cylinder 11 is transferred to the inside of the circulation shell 6, the cooling water inside the circulation shell 6 is switched and connected to the inside of the circulation shell 6, so that the cooling water stored in the water storage cylinder 11 is always cooled. Cooling the oil and rapidly exchanging heat with the lubricating oil in the second connecting pipe 4 as it is transferred from the water storage cylinder 11 to the circulation housing 6 , thereby reducing the temperature of the lubricating oil returning to the lubrication station main body 1 , improving the oil cooling efficiency and real-time lubrication effect. As the lubricating oil temperature in the second connecting pipe 4 gradually decreases, the electric contact thermometer 5 monitors the oil temperature in real time, and the temperature control mechanism adjusts the cooling water temperature to maintain the oil temperature between the highest and lowest points set by the electric contact thermometer 5 during cooling. This reduces the impact of the continued decrease in oil temperature on lubrication and ensures the effectiveness of the lubricating oil.

A radiator 16 is fixedly installed on the water tank 14; when working, the cooling water inside the water tank 14 is transported along the first U-shaped tube 9 to the inside of the first installation tube 7 through the action of the first water pump 15, and is transported to the inside of the circulation shell 6, thereby connecting with the cooling water inside the circulation shell 6 and flowing into the second installation tube 8, and then returning to the water tank 14 along the second U-shaped tube 10, thereby completing the one-way circulation flow of the cooling water, and the cooling water inside the water tank 14 is continuously dissipated by the radiator 16 to ensure the cooling effect of the cooling water.

The cooling water entering the water tank 14 continues to circulate and exchange heat after being dissipated by the radiator 16, and the cooling water entering the second water pump 17 is transported to the inside of the annular shell 18 along the water outlet end of the second water pump 17, and the fan-shaped groove 20 at the connecting position of the first U-shaped tube 9 is sealed by the semicircular baffle 23. The semicircular baffle 23 is driven to rotate by the output shaft of the first motor 24, so that the semicircular baffle 23 gradually reduces the shielding of the fan-shaped groove 20 at the connection position of the first U-shaped tube 9, and correspondingly increases the shielding of the fan-shaped groove 20 at the connection position of the guide tube 25, so that the cooling water inside the annular shell 18 that has not been radiated enters the corresponding semicircular shell 21 along the other fan-shaped groove 20, and enters the water storage tank 14 along the connection position of the corresponding semicircular shell 21 and the guide tube 25 for heat absorption and cooling, and recirculates to cool the lubricating oil. When the electric contact thermometer 5 detects that the temperature of the lubricating oil is gradually decreasing and approaching the lowest point, the semicircular baffle 23 is driven to rotate by the output shaft of the first motor 24, so that the semicircular baffle 23 gradually reduces the shielding of the fan-shaped groove 20 at the connection position of the first U-shaped tube 9, and correspondingly increases the shielding of the fan-shaped groove 20 at the connection position of the guide tube 25, so that the cooling water inside the annular shell 18 that has not been radiated enters the water storage tank 14 along the connection position of the corresponding semicircular shell 21 and ... The corresponding semicircular shell 21 enters the first U-shaped tube 9 and is mixed with the cooling water after heat dissipation at the other end of the first U-shaped tube 9, and is then synchronously transported to the inside of the circulation shell 6, so that the temperature of the cooling water is increased after the cooling water that has not dissipated heat inside the semicircular shell 21 is added and mixed, preventing the lubricating oil inside the second connecting tube 4 from continuously cooling and falling below the lowest point, ensuring the use effect of the lubricating oil, and adjusting the addition ratio of the cooling water that has not been cooled by the rotation of the semicircular baffle 23. When the semicircular baffle 23 rotates one hundred and eighty degrees from the initial position, all the cooling water that has not been cooled inside the annular shell 18 enters the first U-shaped tube 9 and is mixed with the cooling water that has been cooled in the other end of the first U-shaped tube 9 and transported, so that the mixed temperature of the cooling water reaches the maximum value.

The cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11, and the cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11. The cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11, and the cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11. When the cooling water is stored in the water storage cylinder 11, the cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11. When the cooling water is transferred to the inner surface of the water storage cylinder 6, the cooling water in the water storage cylinder 11 is connected to the inner surface of the water storage cylinder 11. When the inside of the water storage cylinder 11 is transferred to the inside of the circulation shell 6, the lubricating oil inside the second connecting pipe 4 can be directly and quickly exchanged with heat, thereby reducing the temperature of the lubricating oil flowing back to the lubrication station main body 1, improving the cooling efficiency of the oil temperature and the real-time lubrication effect. When the temperature of the lubricating oil inside the second connecting pipe 4 gradually decreases, the oil temperature is monitored in real time by the electric contact thermometer 5, and the temperature of the cooling water is adjusted under the action of the temperature control adjustment mechanism, so that the oil temperature is maintained between the highest point and the lowest point set by the electric contact thermometer 5 during cooling, reducing the impact of the continuous decrease in oil temperature on lubrication, and ensuring the use effect of the lubricating oil.
