DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 In the embodiment of the utility model, a coal mine ventilation device that is easy to install includes a ventilator 1, two sets of driving motors for ventilation are fixedly connected inside the ventilator 1, and fan blades are fixedly connected to the output shafts of the driving motors. The upper end of the ventilator 1 is also movably connected to a mounting frame 2 for connecting to the top of the mine tunnel;

[0021] The ventilator 1 includes a main pipeline 100 and a secondary pipeline 101. Two driving motors are respectively located in the main pipeline 100 and the secondary pipeline 101. In order to prevent foreign matter from being sucked into the ventilator 1, the ends of the main pipeline 100 and the secondary pipeline 101 that are away from each other are fixedly connected with an isolation net 102. In order to facilitate the installation of the ventilator 1, the main pipeline 100 and the secondary pipeline 101 are detachably connected.

[0022] Specifically, one end of the main pipe 100 close to the secondary pipe 101 is fixedly connected with an adjusting pipe 103 with a telescopic function, and the adjusting pipe 103 is a corrugated pipe. One end of the adjusting pipe 103 away from the main pipe 100 is rotatably connected with a docking sleeve 104, and the docking sleeve 104 is threadedly connected to the secondary pipe 101. When the docking sleeve 104 is connected to the secondary pipe 101, the main pipe 100 can be pulled to control the length of the docking sleeve 104, thereby controlling the overall length of the ventilator 1, thereby preventing the ventilator 1 from being too large and affecting the installation efficiency.

[0023] The outer sleeve of the secondary pipe 101 is provided with a connecting sleeve 105 for connecting with the ventilation pipe, and a clamping gap 107 is formed between the connecting sleeve 105 and the outer wall of the secondary pipe 101. In order to allow the connecting sleeve 105 to tightly clamp the main ventilation pipe, a supporting spring 106 is also sleeved on the outer wall of the secondary pipe 101. Specifically, two protrusions are provided on the outer wall of the secondary pipe 101, and the connecting sleeve 105 is located between the two protrusions, and the supporting spring 106 is also located between the two protrusions. The supporting spring 106 can push the connecting sleeve 105 to move toward the protrusions on the surface of the secondary pipe 101, so that the ventilation pipe is clamped by the cooperation of the connecting sleeve 105 and the secondary pipe 101;

[0024] Embodiment 2:

[0025] See also Figure 1 and 2, based on Example 1, the mounting frame 2 includes two groups of symmetrically arranged fixing plates 200, and the outer walls of the main pipeline 100 and the auxiliary pipeline 101 are fixedly connected with adjustment plates 203 movably connected to the fixing plates 200. Specifically, a sliding track 201 is provided at the lower end of the fixing plate 200, and the upper end of the adjustment plate 203 is slidably installed in the sliding track 201. More specifically, in order to ensure that the adjustment plate 203 does not separate from the sliding track 201, the upper end of the adjustment plate 203 is set to a "T" shape, and the shape of the sliding track 201 is adapted to the shape of the upper end of the adjustment plate 203. More specifically, the side walls of the fixing plate 200 are respectively threadedly connected with limiting bolts 202, and the limiting bolts 202 can also prevent the adjustment plate 203 from separating from the fixing plate 200;

[0026] The upper ends of the two fixing plates 200 are rotatably connected with lower threaded sleeves 205, the upper ends of the lower threaded sleeves 205 are threadedly connected with threaded rods 204, the upper ends of the threaded rods 204 are threadedly connected with upper threaded sleeves 206, and the outer wall of the upper threaded sleeves 206 is also provided with threads.

[0027] The working principle of the utility model is:

[0028] When the utility model is used, a hole is first opened at the top of the mine tunnel, and then the upper threaded sleeve 206 is screwed into the opened hole. After the upper threaded sleeve 206 is installed, the threaded rod 204 is respectively threadedly connected with the upper threaded sleeve 206, and then the fixing plate 200 is connected to the threaded rod 204 by using the lower threaded sleeve 205. The horizontality of the fixing plate 200 can also be adjusted by rotating the lower threaded sleeve 205. In this way, the angle of the ventilator 1 can be adjusted. After the fixing plate 200 is installed, the main pipeline 1 is sequentially connected. 00 and the adjusting plate 203 on the auxiliary pipe 101 are inserted into the sliding track 201. Specifically, the limiting bolt 202 is first screwed down before the adjusting plate 203 is inserted into the sliding track 201. When the adjusting plate 203 enters the sliding track 201, the limiting bolt 202 is screwed down to limit the adjusting plate 203. Finally, the connecting sleeve 105 and the auxiliary pipe 101 are threadedly connected together to complete the installation of the fan 1. In this way, the problem of the fan 1 being too large and affecting the installation efficiency can be avoided.

[0029] When the ventilator 1 needs to be connected to the ventilation pipe, first push the connecting sleeve 105 to compress the supporting spring 106, then put the ventilation pipe on the outside of the auxiliary pipe 1, and keep the ventilation pipe in the clamping gap 107, and then loosen the connecting sleeve 105 to clamp the ventilation pipe. In this way, the ventilation pipe can be quickly connected to the ventilator 1, thereby increasing the installation efficiency of the ventilator 1.
