DETAILED DESCRIPTION

[0031] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 6 As shown, a cycle furnace electric actuator cooling device of the utility model includes a box body 1, the box body 1 is fixedly mounted on the electric actuator 3, and then the cooling gas 2 is injected into the box body 1 through the injection joint 15. In this embodiment, the cooling gas 2 uses nitrogen, so that the electric actuator 3 can be cooled to improve the use efficiency of the electric actuator 3. In this embodiment, a through hole that is transparent from top to bottom is opened at the bottom of the box body 1, and a cycle furnace is provided below the box body 1. The electric actuator 3 is installed on the top of the cycle furnace. The electric actuator 3 passes through the through hole and is located in the box body 1. Through the setting of the through hole, the electric actuator 3 can pass through the through hole and is located in the box body 1, so that the electric actuator 3 can be cooled.

[0033] In this embodiment, in order to facilitate the cooling of the electric actuator 3, a cooling gas 2 is provided in the box body 1 to cool the electric actuator 3. The height of the cooling gas 2 only needs to exceed that of the electric actuator 3, so that the electric actuator 3 is completely immersed in the cooling gas 2, and the electric actuator 3 can be better cooled by the cooling gas 2.

[0034] In this embodiment, T1, T2, T3, and T4 are all temperature ranges. T1 is lower than T2 as the lowest temperature, T2 is higher than T1 and lower than T3, T3 is higher than T2 and lower than T4, and T4 is higher than T3 as the highest temperature, so as to form a temperature range of T1 < T2 < T3 < T4.

[0035] Specifically, a temperature sensor 4 is provided on the box body 1. In this embodiment, the model of the temperature sensor 4 is the temperature sensor DS18B20. The temperature sensor 4 is located in the cooling gas 2 to detect the temperature of the cooling gas 2. The temperature sensor 4 can detect the temperature condition of the cooling gas 2, so as to drive the corresponding mechanism to start.

[0036] A multi-stage cooling mechanism is provided on the box body 1. The multi-stage cooling mechanism is electrically connected to the temperature sensor 4, so that the multi-stage cooling mechanism can cool the cooling gas 2 in different ways according to the change of the temperature sensor 4. In this embodiment, the multi-stage cooling mechanism includes two different cooling methods to cool the electric actuator 3. One is to blow by wind to accelerate the gas flow, so that the cooling gas 2 can accelerate to approach the electric actuator 3 to achieve the effect of auxiliary cooling. The other is to extract the gas with high heat for cooling and then transport it back into the box body 1.

[0037] A partition 5 is provided in the box body 1. The partition 5 divides the box body 1 into a cooling chamber 6 and a placement chamber 7 from left to right in sequence. The cooling gas 2 is located in the cooling chamber 6, and the multi-stage cooling mechanism is located in the placement chamber 7.

[0038] The first auxiliary mechanism 8 and the second auxiliary mechanism 10 are both fixedly installed in the placement chamber 7, and the first auxiliary mechanism 8 and the second auxiliary mechanism 10 are both electrically connected to the temperature sensor 4 to control the first auxiliary mechanism 8 and the second auxiliary mechanism 10.

[0039] In this embodiment, when the temperature detected by the temperature sensor 4 reaches T2, the first auxiliary mechanism 8 can be driven to start, so that the cooling gas 2 is blown towards the electric actuator 3 for auxiliary cooling. When the temperature reaches T3, the second auxiliary mechanism 10 can be driven to assist in cooling the cooling gas 2. If the temperature reaches T4, the first auxiliary mechanism 8 and the second auxiliary mechanism 10 can be driven to start simultaneously to cool the cooling gas 2, so as to improve the cooling effect of the electric actuator 3.

[0040] The step-by-step cooling mechanism includes a first auxiliary mechanism 8 and a second auxiliary mechanism 10 .

[0041] In order to facilitate the first auxiliary mechanism 8 to cool the cooling air 2, in this embodiment, the first auxiliary mechanism 8 includes a first driving device 801 and a sprocket group 802. In this embodiment, the first driving device 801 is a first driving servo motor, and the first driving device 801 is fixed on the inner wall of the placement cavity 7.

[0042] The output end of the first driving device 801 is transmission connected to the sprocket group 802. In the present embodiment, the sprocket group 802 is composed of two sprockets and a chain meshing with each other, wherein one of the sprockets is fixedly connected to the output end of the first driving device 801, and the other sprocket is transmission connected to the wind driving component 9 to rotate the wind driving component 9. The end of the sprocket group 802 away from the first driving device 801 is transmission connected to the wind driving component 9, so that the wind driving component 9 rotates to cool the cooling air 2. After the first driving device 801 is driven, it can drive the sprocket group 802 to rotate, and then drive the wind driving component 9 to rotate through the sprocket group 802, so that the cooling air 2 is blown toward the electric actuator 3 for cooling.

[0043] Specifically, the wind driving assembly 9 includes a fan frame 901, a rotating shaft 902, and a plurality of fan blades 903 fixedly installed on the outside of the rotating shaft 902 in a circular array with the rotating shaft 902 as the center. When the rotating shaft 902 rotates, it can drive the fan blades 903 to rotate, thereby cooling the cooling air 2.

[0044] The fan frame 901 is fixedly mounted on the inner top wall of the box body 1 , and the rotating shaft 902 is rotatably arranged on the fan frame 901 . The arrangement of the fan frame 901 can provide a protective effect on the rotating shaft 902 and the fan blades 903 .

[0045] The lower end of the rotating shaft 902 is drivingly connected to the sprocket set 802 to enable the rotating shaft 902 to rotate. When the sprocket set 802 rotates, it can drive the rotating shaft 902 to rotate.

[0046] In order to facilitate the second auxiliary mechanism 10 to cool the cooling gas 2, in this embodiment, the second auxiliary mechanism 10 includes a cooling device 1001 and a suction pump 1002. The cooling device 1001 and the suction pump 1002 are both fixed on the placement cavity 7. In this embodiment, the cooling device 1001 adopts a nitrogen cooler.

[0047] The input end of the suction pump 1002 is connected to the air inlet pipe 11, and the output end of the suction pump 1002 is connected to the air outlet pipe 12. The air outlet pipe 12 is interconnected with the air inlet end of the cooling device 1001. The suction pump 1002 is driven to start, so that the gas can be sucked into the air outlet pipe 12 through the air inlet pipe 11, and then the gas flows into the cooling device 1001 through the air outlet pipe 12 for cooling, so that the gas becomes cool.

[0048] The air outlet of the cooling device 1001 is connected to an exhaust pipe 13 , and both the air inlet pipe 11 and the exhaust pipe 13 pass through the partition 5 and are located in the cooling chamber 6 , and then the cooled gas flows into the cooling chamber 6 through the exhaust pipe 13 to continue cooling the electric actuator 3 .

[0049] Two exhaust pipes 14 spaced apart from each other are fixedly provided on the cooling device 1001 to discharge the exhaust gas in the cooling device 1001 . The exhaust pipes 14 can discharge the gas in the cooling device 1001 .

[0050] The top of the box body 1 is provided with a filling joint 15 for filling the cooling chamber 6 with gas. When the filling joint 15 is connected, the cooling gas 2 can be injected into the cooling chamber 6 to cool the electric actuator 3 .

[0051] Working principle: When in use, connect the filling joint 15, inject the cooling gas 2 into the cooling chamber 6, and then disconnect the filling joint 15 after the injection.

[0052] The injection of cooling air 2 can cool down the electric actuator 3 to improve the efficiency of the electric actuator 3. This temperature is the T1 stage. When the temperature detected by the temperature sensor 4 reaches T2, the first driving device 801 can be driven to start, so that the sprocket group 802 is driven to rotate, and then the rotating shaft 902 is driven by the sprocket group 802. When the rotating shaft 902 rotates, it can drive the fan blades 903 to rotate, so that the cooling air 2 is blown near the electric actuator 3 to accelerate the cooling.

[0053] When the temperature detected by the temperature sensor 4 reaches T3, the cooling device 1001 and the suction pump 1002 can be driven to start, so that after the suction pump 1002 is started, the gas can be sucked into the outlet pipe 12 through the air inlet pipe 11, and then the gas flows into the cooling device 1001 through the air outlet pipe 12 for cooling, so that the hot gas becomes cool and is transported back to the vicinity of the electric actuator 3.

[0054] When the temperature detected by the temperature sensor 4 reaches T4, the first driving device 801, the cooling device 1001 and the suction pump 1002 are all started, which can not only replace the cooling air 2, but also blow the cooling air 2 toward the electric actuator 3 to reduce the temperature of the electric actuator 3.
