[0004] Although the above technology has a good lubrication control effect on the coal mine lubrication device when used, it does not have corresponding dustproof and heat dissipation components for precision components such as PLC. Therefore, in actual use, the harsh operating environment in the coal mine can easily lead to poor heat dissipation and dust accumulation of precision components in the electronic control device, resulting in unstable operation of the electronic control device. Therefore, in order to solve the above technical defects, we proposed an electronic control device for coal mine lubrication devices. Utility Model Content

[0025] Example 2

[0026] Reference Figure 1-4 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] The installation shell 1 and the corresponding sealing door 2 at the hatch are equipped with matching sealing rings 10, and an air venting pipe 11 is installed on one side of the upper end of the installation shell 1. A temperature measuring component is installed on the pipe body of the air venting pipe 11. The setting of the sealing ring 10 is convenient for sealing between the sealing door 2 and the installation shell 1, so as to prevent external dust from entering the interior of the installation shell 1 and causing adverse effects on the main body 3 of the electric control device. The temperature measuring component is a common component with a gas temperature measurement function, which will not be described in detail in this scheme. In actual use, personnel can choose it as appropriate. That is, the temperature of the exhaust air is measured through the temperature measuring component, so that the device can adjust the air output of the air pump 7; the lower end of the liquid storage barrel 4 is in an open state, and a collecting box 12 is installed at the opening of the lower end of the liquid storage barrel 4. The setting of the collecting box 12 is convenient for collecting the settled dust. The collecting box 12 is connected to the liquid storage barrel 4 through a thread. The body wall of the collecting box 12 is a transparent body wall, and the transparent body wall makes it convenient for personnel to observe the amount of dust settled inside the collecting box 12, so that the dust in the collecting box 12 can be cleaned in time.

[0028] A threaded hole is provided on one side of the upper end of the liquid storage barrel 4, and a sealing plug 13 is installed on the liquid storage barrel 4 through the threaded hole. The setting of the sealing plug 13 is convenient for sealing the liquid storage barrel 4, and is also convenient for subsequent personnel to add water into it; a moisture absorbing block 14 is installed inside the air outlet pipe 8, and the outside of the liquid storage barrel 4 and the air outlet pipe 8 are wrapped with a thermal insulation layer. The setting of the moisture absorbing block 14 reduces the amount of water vapor entering the interior of the installation shell 1; the regulating tube 6 is a universal tube, and an observation window 15 is provided in the middle of the sealing door 2, and a hygrometer 16 is provided on the observation window 15. The setting of the observation window 15 is convenient for personnel to conveniently observe the operating status of the electric control device body 3 inside the installation shell 1 from the outside, and the setting of the hygrometer 16 is convenient for monitoring the humidity of the air inside the installation shell 1, so as to make the internal environment of the installation shell 1 in an environment that is more suitable for the operation of the electric control device body 3.

[0029] Principle and advantages of use: During the use of the utility model, the air pump 7 pumps gas into the air inlet pipe 5, and the gas goes deep into the bottom of the liquid storage barrel 4 along the air inlet pipe 5, and then the gas moves upward at the bottom of the liquid storage barrel 4, and finally sprays from the air outlet pipe 8 to the inside of the installation shell 1 through the regulating pipe 6, so as to dissipate heat for the main body 3 of the electric control device inside the installation shell 1. In the above process, since there is clean water inside the liquid storage barrel 4, that is, when the gas moves upward at the bottom of the liquid storage barrel 4, the dust in the gas combines with the clean water, and at this time, a good dust removal effect is achieved on the gas, thereby avoiding the inlet. The gas entering the installation shell 1 contains a lot of dust, which causes the unstable operation of the electronic control device body 3. Since the adjustment tube 6 is a universal tube, the personnel can point the adjustment tube 6 to the heating place according to the heating degree of each component in the electronic control device body 3, so that the electronic control device body 3 can have a more effective air-cooling and heat dissipation effect. In addition, since the gas needs to pass through the clean water inside the liquid storage barrel 4, it can cool the gas to a certain extent, that is, when the cooled gas dissipates heat to the electronic control device body 3, its heat dissipation effect is further improved.

[0030] At the same time, in the above process, since there are two air pumps 7, when the device is in use, if one of the air pumps 7 is damaged, the air intake pipe 5 can be supplied with air through the other air pump 7, so that the present solution has better sustainability, thereby avoiding the phenomenon that when the air pump 7 is accidentally damaged, it is unable to dissipate heat for the electronic control device body 3, that is, further improving the stability of the electronic control device body 3 when in use.

[0031] It should be further explained that the various electrical components in this scheme are connected to the main body 3 of the electric control device, that is, they are controlled by the main body 3 of the electric control device; the setting of the sealing ring 10 is convenient for sealing between the sealing door 2 and the installation shell 1, so as to prevent external dust from entering the interior of the installation shell 1 and causing adverse effects on the main body 3 of the electric control device, and the temperature of the exhaust air is measured by the temperature measuring element, so that the device adjusts the air delivery of the air pump 7; the setting of the collection box 12 is convenient for collecting the settled dust, and the transparent body wall is convenient for personnel to observe the collection box 1 2, so that the dust in the collecting box 12 can be cleaned in time; the cooperation between the sealing plug 13 and the threaded hole is convenient for subsequent personnel to add water into it; the setting of the moisture absorbing block 14 reduces the amount of water vapor entering the inside of the installation shell 1; the setting of the observation window 15 is convenient for personnel to observe the operating status of the main body 3 of the electric control device inside the installation shell 1 from the outside, and the setting of the hygrometer 16 is convenient for monitoring the humidity of the air inside the installation shell 1, so as to make the internal environment of the installation shell 1 in an environment more suitable for the operation of the main body 3 of the electric control device.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
