Description

Technical Field

[0001] The invention belongs to the technical field of explosion-proof motors, and in particular relates to an explosion-proof motor and a control system for gas odorization. Background Art

[0002] Gas odorization is an important safety measure. By adding an odorant with a strong odor to the gas, gas leaks can be discovered in time, thus avoiding accidents such as poisoning and explosions. When adding the odorant, the odorant is often transported by a pump equipped with a motor. In order to avoid the arc generated by the operation of ordinary motors causing combustion or explosion, explosion-proof motors are often used to improve the safety of gas odorization. In order to facilitate the heat dissipation of explosion-proof motors, water-cooling heat dissipation mechanisms or air-cooling heat dissipation mechanisms are generally set outside the motor.

[0003] In existing explosion-proof motors used for gas odorization, the water-cooling pipes are usually long, so that the distance that water moves in the pipes is long. The water absorbs the heat of the outer casing in the pipes and is difficult to dissipate the heat to the outside, so that the temperature of the water continues to rise and is difficult to reduce during the long-distance movement, which weakens the ability of the water to absorb heat, resulting in insufficient heat dissipation efficiency of water cooling. In addition, the air inlet and air outlet of the air cooling are usually fixed, so that the gas flow trajectory formed between the air inlet and the air outlet is also fixed, which leads to uneven heat dissipation of the motor body by air cooling and insufficient heat dissipation efficiency of air cooling. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0046] Example 1: Figures 1 to 3As shown, it is the first embodiment of the present invention, which provides an explosion-proof motor and control system for gas odorization, including a motor body 10, on which an output shaft 11 is provided; a shell 20, which is fixedly installed on the outside of the motor body 10; a water cooling mechanism 30, which is arranged on the outside of the shell 20 and is used to dissipate heat from the shell 20, and the water cooling mechanism 30 includes a heat dissipation pipe 31, a heat dissipation fan 32 and a water supply tank 33; an air cooling mechanism 40, which is rotatably installed on the inner wall of the shell 20 and is used to dissipate heat from the motor body 10, and the air cooling mechanism 40 includes an air inlet 41 and an exhaust fan 42, and the air cooling mechanism 40 is drivingly connected to the output shaft 11.

[0047] It should be noted that the output shaft 11 extends out of the housing 20 .

[0048] When the present invention is in use, after the water cooling mechanism 30 works, the heat dissipation fan 32 dissipates heat from the water supply tank 33, reduces the temperature of the water in the water supply tank 33, and makes the water in the water supply tank 33 flow into the heat dissipation pipe 31 and absorb the heat of the shell 20, thereby cooling the equipment. After the motor body 10 works, the output shaft 11 rotates, and the output shaft 11 drives the air cooling mechanism 40 to rotate along the shell 20, so that the air inlet 41 and the exhaust fan 42 rotate along the shell 20, so as to adjust the positions of the air inlet 41 and the exhaust fan 42 on the shell 20, so that the gas enters the shell 20 through the air inlet 41 located at different positions, and is discharged to the outside of the shell 20 through the exhaust fan 42 located at different positions, so as to facilitate uniform heat dissipation of the equipment, and the exhaust fan 42 also blows air to the heat dissipation pipe 31 during the process of rotating along the shell 20, so that the water in the heat dissipation pipe 31 reduces the temperature of the water in the heat dissipation pipe 31 during the long-distance movement, so as to facilitate the water in the heat dissipation pipe 31 to absorb the heat of the shell 20, thereby improving the heat dissipation efficiency of water cooling.

[0049] Example 2: Reference Figures 1 to 10 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0050] like Figure 4 and Figure 5 As shown, an air inlet vent 21 and an air outlet vent 22 are provided on the inner wall of the housing 20 , and a connecting plate 23 is fixedly connected to the inner wall of the housing 20 , and the connecting plate 23 is fixedly connected to the motor body 10 .

[0051] It should be noted that the motor body 10 and the housing 20 are fixedly connected together via a connecting plate 23 .

[0052] According to the above structure, after the air inlet 41 rotates along the air inlet vent 21, the air inlet position at the air inlet vent 21 is adjusted, and after the exhaust fan 42 rotates along the air outlet vent 22, the exhaust position at the air outlet vent 22 is adjusted, thereby adjusting the gas flow trajectory formed between the air inlet 41 and the exhaust fan 42, which is convenient for uniform heat dissipation of the equipment.

[0053] like Fig. 9 and Fig.10 As shown, the heat dissipation pipe 31 is fixedly connected to the outer wall of the shell 20, the water supply tank 33 is fixedly connected to the top of the shell 20, the top of the water supply tank 33 is fixedly connected with the heat dissipation fins 34, the heat dissipation fan 32 is fixedly connected to the top of the heat dissipation fins 34, both sides of the water supply tank 33 are connected to the heat dissipation pipe 31, the inside of the water supply tank 33 is slidably connected with a push plate 35, the push plate 35 is transmission-connected to the heat dissipation fan 32, and the inside of the push plate 35 is fixedly connected with a plurality of one-way valves 351.

[0054] It should be noted that the heat dissipation fins 34 are prior art and are usually made of a number of thin metal sheets arranged in a certain shape and spacing, and are used to optimize air flow and improve heat dissipation efficiency, which will not be described in detail here.

[0055] According to the above structure, after the cooling fan 32 starts working, the heat of the water supply tank 33 is discharged to the outside through the cooling fins 34. At the same time, the cooling fan 32 also drives the push plate 35 to slide along the inside of the water supply tank 33, so that the push plate 35 pushes the water in the water supply tank 33 to move to the heat dissipation pipe 31 and return to the inside of the water supply tank 33, so that the water in the water supply tank 33 and the heat dissipation pipe 31 circulates and absorbs the heat of the outer shell 20.

[0056] like Fig. 9 As shown, the heat dissipation pipe 31 is formed by connecting continuous S-shaped pipes in sequence and surrounds the outer shell 20. The top two sides of the heat dissipation pipe 31 are fixedly connected with a water inlet pipe 311 and a water outlet pipe 312, and the water inlet pipe 311 and the water outlet pipe 312 are respectively connected to the two sides of the water supply box 33.

[0057] It should be noted that the one-way valve 351 only allows the water in the water delivery tank 33 to move in one direction from the side close to the water inlet pipe 311 to the side close to the water outlet pipe 312 .

[0058] According to the above structure, the water in the water supply tank 33 flows into the heat dissipation pipe 31 through the water outlet pipe 312, is divided into two paths, each moves half a circle along the outer shell 20 and then merges, and flows into the water supply tank 33 through the water inlet pipe 311. The water absorbs the heat of the outer shell 20 during this flow process.

[0059] like Fig.10As shown, the cooling fan 32 includes a frame 321 fixedly connected to the cooling fins 34, a double-headed motor 322 is fixedly connected inside the frame 321, one output end of the double-headed motor 322 is fixedly connected to a cooling blade 323, and the other output end of the double-headed motor 322 is fixedly connected to a rotating shaft 36, and the end of the rotating shaft 36 extending into the water supply tank 33 is fixedly connected to an eccentric wheel 37, and a sleeve 38 is rotatably connected to the outer side of the eccentric wheel 37, and a connecting rod 39 is provided between the sleeve 38 and the push plate 35, one end of the connecting rod 39 is rotatably connected to the sleeve 38, and the other end of the connecting rod 39 is fixedly connected to the push plate 35.

[0060] It should be noted that the axis of the eccentric wheel 37 is offset from the axis of the rotating shaft 36. The double-headed motor 322 is a prior art. The double-headed motor 322 has two output ends which are respectively located on both sides of the double-headed motor 322, which will not be described in detail here.

[0061] According to the above structure, after the double-headed motor 322 works, one output end drives the heat dissipation blade 323 to rotate to dissipate heat to the water delivery box 33. At the same time, the other output end of the double-headed motor 322 drives the rotating shaft 36 to rotate. The rotating shaft 36 drives the eccentric wheel 37 to rotate around the axis of the rotating shaft 36. The rotating shaft 36 drives the eccentric wheel 37 to rotate. The eccentric wheel 37 drives the push plate 35 to slide along the water delivery box 33 through the sliding sleeve 38 and the connecting rod 39. Since the axis of the eccentric wheel 37 is offset from the axis of the rotating shaft 36, the rotating shaft 36 drives the push plate 35 to slide back and forth along the water delivery box 33 through the eccentric wheel 37, the sliding sleeve 38 and the connecting rod 39. When the push plate 35 slides to the side close to the water inlet pipe 311, the water in the water delivery box 33 close to the water inlet pipe 311 passes through the sliding sleeve 38 and the connecting rod 39. When the push plate 35 slides toward the side close to the water outlet pipe 312, the water in the water supply tank 33 close to the water outlet pipe 312 cannot pass through the one-way valve 351, so the push plate 35 pushes the water in the water supply tank 33 close to the water outlet pipe 312 to move into the heat dissipation pipe 31. At the same time, the water in the heat dissipation pipe 31 moves to the side close to the water inlet pipe 311 of the water supply tank 33 through the water inlet pipe 311, thereby realizing the circulation of water in the water supply tank 33 and the heat dissipation pipe 31, making it convenient for the heat dissipation fan 32 to cool down the water in the water supply tank 33 while allowing the water to circulate in the heat dissipation pipe 31 and the water supply tank 33. Compared with the traditional method, the need for a water pump to drive the water circulation is reduced, thereby improving the linkage and compactness of the equipment.

[0062] like Figures 6 to 8As shown, the air cooling mechanism 40 also includes a first rotating cylinder 43 rotatably connected to the air inlet vent 21, the first rotating cylinder 43 is transmission-connected to the output shaft 11, the air inlet 41 is opened on the first rotating cylinder 43, the air outlet vent 22 is rotatably connected to the second rotating cylinder 44, the second rotating cylinder 44 is fixedly connected to the first rotating cylinder 43, the exhaust fan 42 is fixedly connected to the second rotating cylinder 44, the interior of the outer shell 20 is fixedly connected to the first ring gear 24, and the exhaust fan 42 is transmission-connected to the first ring gear 24.

[0063] According to the above structure, after the motor body 10 is working, the output shaft 11 rotates, and the output shaft 11 drives the first rotating cylinder 43 to rotate, so that the first rotating cylinder 43 drives the air inlet 41 to rotate along the air inlet vent 21 to adjust the position of the air inlet 41 on the air inlet vent 21, so that the gas can enter the interior of the outer shell 20 through the air inlet 41 at different positions on the air inlet vent 21, and the first rotating cylinder 43 drives the second rotating cylinder 44 to rotate, and the second rotating cylinder 44 drives the exhaust fan 42 to rotate along the air outlet vent 22 to adjust the position of the exhaust fan 42 on the air outlet vent 22, so that the gas can be discharged to the outside of the outer shell 20 through the exhaust fan 42 at different positions on the air outlet vent 22.

[0064] like Figures 6 to 8 As shown, the interior of the first rotating cylinder 43 is fixedly connected to the second gear ring 451, the output shaft 11 is fixedly connected to the first pulley 452, the inner wall of the outer shell 20 is rotatably connected to the first connecting shaft 453, the end of the first connecting shaft 453 close to the second gear ring 451 is fixedly connected to the first gear 454, the first gear 454 is meshed with the second gear ring 451, the end of the first connecting shaft 453 close to the first pulley 452 is fixedly connected to the second pulley 455, and the second pulley 455 is transmission-connected to the first pulley 452.

[0065] It should be noted that a transmission belt is connected between the first pulley 452 and the second pulley 455 , and the first pulley 452 and the second pulley 455 are connected through the transmission belt.

[0066] According to the above structure, after the output shaft 11 rotates, it drives the first connecting shaft 453 to rotate through the first pulley 452 and the second pulley 455. The first connecting shaft 453 drives the first rotating cylinder 43 to rotate through the first gear 454 and the second gear ring 451, so that the output shaft 11 drives the first rotating cylinder 43 to rotate, so that the air inlet 41 changes position with the rotation of the output shaft 11.

[0067] like Figures 6 to 8As shown, the exhaust fan 42 includes a frame 421 fixedly connected to the second rotating cylinder 44, the frame 421 has an exhaust blade 422 rotatably connected inside, one side of the exhaust blade 422 is fixedly connected to a first bevel gear 461, a second connecting shaft 462 is rotatably connected to the inner wall of the second rotating cylinder 44, an end of the second connecting shaft 462 close to the first bevel gear 461 is fixedly connected to a second bevel gear 463, the second bevel gear 463 is meshed with the first bevel gear 461, and an end of the second connecting shaft 462 close to the first ring gear 24 is fixedly connected to a second gear 464, the second gear 464 is meshed with the first ring gear 24.

[0068] The second gear 464 is meshed with the first gear ring 24, so that the second connecting shaft 462 rotates along the first gear ring 24, and the second gear 464 also drives the second connecting shaft 462 to roll along the first gear ring 24, so that the second connecting shaft 462 drives the second bevel gear 463 to rotate, and the second bevel gear 463 drives the exhaust blade 422 to rotate through the first bevel gear 461, so that the exhaust fan 42 changes its position along the air outlet vent 22, and the exhaust fan 42 also blows air to the outside to discharge the heat inside the outer shell 20, so that the exhaust fan 42 changes its position while cooling the equipment, and the exhaust fan 42 also blows air to the heat dissipation duct 31 outside the outer shell 20 during the rotation of the exhaust fan 42 along the air outlet vent 22, so as to dissipate the water in the heat dissipation duct 31.

[0069] like Figure 7 and Figure 8 As shown, a gas sensor 47 is fixedly connected inside the air inlet 41 for detecting the odorant.

[0070] It should be noted that the odorant is a liquid with low volatility but still has a pungent smell at extremely low concentrations. After the odorant leaks and evaporates, tetrahydrothiophene exists in the air. The gas sensor 47 is a prior art that detects odorant leakage by detecting tetrahydrothiophene in the air, which will not be described in detail here.

[0071] According to the above structure, when the air inlet 41 rotates along the air inlet vent 21, the air inlet 41 also drives the gas sensor 47 to rotate, so that when the gas enters the interior of the shell 20 through the air inlet 41, the gas sensor 47 detects the gas. Moreover, since the position of the air inlet 41 on the air inlet vent 21 is constantly changing, the gas sensor 47 detects the gas at different positions around the equipment, thereby improving the convenience of odorant detection and the reliability of odorant leakage detection.

[0072] Example 3: Reference Fig.11 , which is the third embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0073] like Fig.11 As shown, a control system of an explosion-proof motor for gas odorization, the control system is applicable to the explosion-proof motor for gas odorization in any one of Embodiment 1 and Embodiment 2, comprising:

[0074] A data acquisition module, which is used to obtain gas leakage information, including gas type and gas concentration. The data acquisition module includes multiple sensors, and the multiple sensors are all compatible with the power supply module;

[0075] An alarm module, which is used to send alarm information to the user;

[0076] The control module is used to control the activation of the alarm module according to the gas leakage information.

[0077] In this embodiment, when odorant leakage occurs during the gas odorization process, the data acquisition module obtains gas leakage information through the sensor and transmits it to the control module. The control module activates the alarm module according to the gas leakage information, so that the alarm module sends an alarm message to the user, thereby improving the safety of gas odorization.

[0078] Example 4: Reference Fig.12 , which is the fourth embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0079] like Fig.12 As shown, the structure of the non-exhaust liquid replenishing device of the differential pressure odorizing device includes a normal pressure liquid storage tank, an exhaust gas filter, a pump, a controller, a liquid level sensor, a flame arrester, a filter, a one-way valve and a valve.

[0080] The non-exhaust liquid replenishing device senses the liquid level height of the pressure storage tank of the differential pressure odorizing device through the upper and lower sensors. When the liquid level of the pressure storage tank reaches the lower sensor, the lower sensor sends a signal to the controller of the non-exhaust liquid replenishing device. The controller controls the pump to work, and the pump transports the odorant in the atmospheric pressure tank to the pressure storage liquid. When the odorant level height in the pressure storage tank increases to the upper sensor, the upper sensor sends a signal to the controller of the non-exhaust liquid replenishing device. The controller turns off the pump and the non-exhaust liquid replenishing device stops working.

[0081] This explosion-proof motor is an explosion-proof servo motor, which is installed on the pump head of the metering pump to form an explosion-proof servo motor hydraulic diaphragm metering pump. The explosion-proof servo motor has a fast response speed, stable output torque and speed, and is not easily affected by the working environment. The pump in the traditional method is an explosion-proof variable frequency motor hydraulic diaphragm metering pump. The explosion-proof variable frequency motor in the explosion-proof variable frequency motor hydraulic diaphragm metering pump cannot work under conditions below 5HZ (which can be converted into speed). If the motor works under low HZ conditions for a long time, it will heat up seriously and burn the motor. Compared with the explosion-proof variable frequency motor, the explosion-proof servo motor avoids the situation where it cannot work under conditions below 5HZ, and avoids the situation where the motor is burned due to severe heating under low speed conditions. Compared with the situation where explosion-proof variable frequency motors are used in the traditional method, by using explosion-proof servo motors instead of explosion-proof variable frequency motors, the situation where the explosion-proof variable frequency motor hydraulic diaphragm metering pump cannot work under low gas flow conditions of gas odorization is avoided.

[0082] The working principle of the present invention is as follows: after the water cooling mechanism 30 works, it absorbs the heat of the outer shell 20 through the heat dissipation pipe 31 to reduce the temperature of the equipment. After the heat dissipation fan 32 works, it cools the water supply tank 33 and also allows water to circulate in the heat dissipation pipe 31 and the water supply tank 33, thereby improving the linkage and compactness of the equipment. After the motor body 10 works, it drives the air cooling mechanism 40 to rotate along the outer shell 20 through the output shaft 11 to adjust the position of the air inlet 41 and the exhaust fan 42, so as to change the gas flow trajectory formed between the air inlet 41 and the exhaust fan 42, thereby facilitating uniform heat dissipation of the equipment. At the same time, the rotating exhaust fan 42 also blows air to the heat dissipation pipe 31 for heat dissipation, thereby improving the heat dissipation efficiency of water cooling.

[0083] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
