Description

Technical Field

[0001] The utility model relates to the technical field of coal mine ventilation monitoring, in particular to ventilation safety monitoring equipment for coal mines. Background Art

[0002] Coal mines refer to places rich in coal resources, which are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people usually choose to dig tunnels underground to mine coal. This is an underground coal mine. Mine ventilation refers to the input of fresh air into the mine to increase the oxygen concentration, so as to dilute and remove toxic and harmful gases and dust in the mine, and provide enough fresh air underground to meet the oxygen needs of personnel. During ventilation, ventilation safety monitoring devices are required to monitor the air in the mine.

[0003] When the existing ventilation safety monitoring equipment for coal mines is in use, due to the high concentration of dust raised in the working environment of the underground mine, dust and impurities are easily accumulated in the monitoring device after long-term use, which may interfere with normal monitoring and affect its working stability. The monitoring device usually plays a protective role through the outer casing. When a lot of gravel falls on it, the gravel directly collides with the outer casing of the monitoring device. The outer casing is easily deformed by force and squeezes the internal components, which may reduce the service life. Utility Model Content

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, a ventilation safety monitoring device for coal mines includes a ventilation monitoring device body 2 mounted on a base frame 1, and a protection component 3 is provided at the front end of the ventilation monitoring device body 2;

[0024] The protection component 3 includes a connecting frame 4, which is installed at the front end of the ventilation monitoring equipment body 2 by connecting bolts, and air outlets are opened at both ends of the connecting frame 4. A filter cylinder net 5 is rotatably installed at the front end of the connecting frame 4, and a cleaning brush roller 6 is rotatably installed at the front end of the connecting frame 4 and located at the lower position of the outer ring of the filter cylinder net 5. A cleaning motor 7 is installed on one side of the connecting frame 4, and the driving shaft of the cleaning motor 7 is connected to the filter cylinder net 5 and the cleaning brush roller 6 through a transmission wheel group 8. A mounting frame 9 is fixedly connected to the lower position of the front end of the connecting frame 4, a mounting groove is opened at the top of the mounting frame 9, and an impurity collection frame 10 is movably installed inside the mounting groove.

[0025] In this embodiment, the outer ring of the cleaning brush roller 6 is in contact with the outer ring of the filter cylinder net 5, and the cleaning brush roller 6 does not contact the impurity collection frame 10. By starting the cleaning motor 7, the cleaning brush roller 6 is driven to rotate to clean the impurities on the filter cylinder net 5, so as to facilitate brushing off the impurities blocked thereon, thereby avoiding a large number of impurities causing significant interference to the normal air circulation at the filter cylinder net 5.

[0026] In this embodiment, a handle is fixedly connected to the front end of the impurity collection frame 10, and elastic fasteners matching the impurity collection frame 10 are movably installed on both sides of the front end of the mounting frame 9. The cleaned dust can be collected through the impurity collection frame 10, so that subsequent personnel can detect the dust as needed.

[0027] In the present embodiment, a supporting top plate 11 is fixedly connected to the top of the ventilation monitoring device body 2, and mounting rods 13 are movably installed at the four corners through the upper and lower ends of the supporting top plate 11, and the two mounting rods 13 at the same end form a group, and the top of each group of mounting rods 13 is fixedly connected to a protective plate 12, and the tops of the two protective plates 12 are installed with protective plate 2 15 through fixing bolt 1, and the tops of the two protective plates 2 15 are installed with protective plate 3 16 through fixing bolt 2. The protective plates 3 16, 15, and 12 are used to block the gravel, thereby preventing it from directly contacting the protective shell of the ventilation monitoring device body 2, and preventing the ventilation monitoring device body 2 from being damaged by the gravel.

[0028] In this embodiment, a buffer spring 14 is provided around the outer ring of the mounting rod 13 and between the protective plate 12 and the supporting top plate 11, and the two ends of the buffer spring 14 are respectively in contact with the upper and lower opposite surfaces of the protective plate 12 and the buffer spring 14. When gravel falls onto the protective plate 3 16, the protective plate 2 15, and the protective plate 1 12, the buffer spring 14 will be compressed, and the buffer spring 14 will have a certain buffering effect on the impact force through the timely and effective deformation of the buffer spring 14.

[0029] In this embodiment, a rubber buffer pad matching the protective plate 12 is provided on the top surface of the support top plate 11, an external thread is provided at the lower position of the outer ring of the mounting rod 13, and a limiting nut is threadedly connected through the external thread. The rubber buffer pad is provided to facilitate absorption of impact force.

[0030] In this embodiment, the combined shape of the protective plate 12, the protective plate 2 15, and the protective plate 3 16 is a semicircular arc. The protective plate 12 is detachably connected to the protective plate 2 15 by the fixing bolt 1, and the protective plate 2 15 is detachably connected to the protective plate 3 16 by the fixing bolt 2. The combination of the protective plate 12, the protective plate 2 15, and the protective plate 3 16 facilitates the sliding of gravel and avoids the accumulation of gravel on the top to cause excessive pressure. At the same time, the protective plate 12, the protective plate 2 15, and the protective plate 3 16 are not arranged in an integrated manner, and after being deformed after long-term use, they can be easily disassembled and replaced separately.

[0031] It should be noted that the utility model is a ventilation safety monitoring device for coal mines. When in use, first, when the ventilation monitoring device body 2 monitors the air in the underground mine, because the front end of the ventilation monitoring device body 2 is connected to the connecting frame 4, and the air outlet of the connecting frame 4 corresponds to the position of the probe of the ventilation monitoring device body 2, and at the same time, a filter cylinder net 5 is installed at the air outlet of the connecting frame 4, so that when the ventilation monitoring device body 2 monitors the air under the mine, the air needs to enter through the filter cylinder net 5, and the filter cylinder net 5 can play a role in filtering dust impurities in the air, thereby preventing high-concentration dust in the air of the underground mine from accumulating in large quantities at the monitoring probe of the ventilation monitoring device body 2, avoiding a large impact on the normal monitoring of the ventilation monitoring device body 2;

[0032] At the same time, the filter cylinder net 5 is rotatably mounted on the connecting frame 4, and one end of the filter cylinder net 5 is connected to the driving shaft of the cleaning motor 7, and the driving shaft of the cleaning motor 7 is connected to the cleaning brush roller 6 through the transmission wheel group 8, and the outer ring of the cleaning brush roller 6 is in contact with the outer ring of the filter cylinder net 5, so that during the process of the filter cylinder net 5 filtering dust;

[0033] By starting the cleaning motor 7, the driving shaft of the cleaning motor 7 rotates to drive the filter cylinder net 5 and the cleaning brush roller 6 to rotate. Since the filter cylinder net 5 is cylindrical, the rotation of the filter cylinder net 5 can play a role in changing the surface. At the same time, during the surface changing process, the cleaning brush roller 6 rotates to clean the impurities on the filter cylinder net 5, so as to facilitate the brushing off of the impurities blocked thereon, and avoid the large amount of impurities causing great interference to the normal air circulation at the filter cylinder net 5;

[0034] At the same time, since a supporting top plate 11 is provided at the top of the ventilation monitoring device body 2, and the protective plate three 16, the protective plate two 15, and the protective plate one 12 are assembled and installed on the supporting top plate 11 through the mounting rod 13, and a plurality of buffer springs 14 are provided between the supporting top plate 11 and the protective plate one 12, when gravel falls on the ventilation monitoring device body 2, the protective plate three 16, the protective plate two 15, and the protective plate one 12 play a role in blocking the gravel, avoiding direct contact with the protective shell of the ventilation monitoring device body 2, and preventing the ventilation monitoring device body 2 from being damaged by the gravel;

[0035] When the gravel falls onto the protective plate three 16, the protective plate two 15, and the protective plate one 12, the buffer spring 14 will be compressed. The buffer spring 14 will deform in time and effectively to buffer the impact force to a certain extent. At the same time, the protective plate three 16, the protective plate two 15, and the protective plate one 12 are combined to form an arc-shaped protrusion, which can make the fallen gravel slide down and avoid the gravel accumulating on the top and causing damage due to excessive pressure.

Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
