Description

Technical Field

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

[0003] The design of traditional ventilation windows usually does not take the need for drainage into consideration. Therefore, when it rains, water will accumulate on the window frames and cannot be discharged in time. When rainwater enters the coal shed through the ventilation windows, it is easy to cause the coal to become damp and agglomerate, increasing the risk of fire and explosion inside the coal shed, and also easily affecting the quality of the coal. For this reason, a ventilation device for a coal shed is proposed. Utility Model Content

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 Figure 1 , Figure 3 and Figure 4The embodiment of the utility model provides a ventilation device for a coal shed, which includes a frame 100, a plurality of louvers 101 and a plurality of ventilation cavities 102, wherein the plurality of louvers 101 and the plurality of ventilation cavities 102 are arranged at intervals, a water storage cavity 105 is provided at the top of the louver 101, a Tesla valve structure flow channel 106 is provided at the inner bottom of the louver 101, a water inlet end of the Tesla valve structure flow channel 106 is connected with a water diversion channel 107, a water diversion channel 107 is connected with a water diversion groove 108 at the top, a water inlet groove 109 is connected with the ventilation cavity 102, a filter net III 114 is arranged at the top of the water inlet groove 109, a plurality of drainage channels 110 are evenly arranged on the side of the frame 100, a water outlet end of the Tesla valve structure flow channel 106 is connected with the drainage channel 110, and a drainage pipe 112 is installed inside the drainage channel 110.

[0021] According to the above technical scheme, the setting of the water storage cavity 105 and the water diversion channel 107 enables rainwater to be collected and stored on the top of the louver 101, preventing rainwater accumulated on the louver 101 from directly entering the coal shed, which can effectively avoid the problem of coal getting damp and agglomerating. After the rainwater enters the water storage cavity 105, it flows into the water inlet groove 109 and the water diversion groove 108, and finally enters the Tesla valve structure flow channel 106 through the water diversion channel 107. Through the design of the Tesla valve structure flow channel 106, the rainwater can flow through natural gravity and enter the drainage channel 110. Therefore, when it rains, the accumulated water on the louver 101 can be discharged in time to avoid the accumulation of water on the louver 101, thereby reducing the risk of coal getting damp and agglomerating in the coal shed. At the same time, the drainage channel 110 ensures that the accumulated water can be quickly and effectively discharged from the coal shed, avoiding the risk of fire and explosion caused by accumulated water, and ensuring that the quality of the coal is not affected.

[0022] In one embodiment of the present invention, Figure 1 As shown, a filter net Ⅰ 104 is installed on the top of the louver 101. This arrangement prevents dust and particles from entering the water storage chamber 105 and causing blockage, ensuring normal drainage in rainy weather.

[0023] In one embodiment of the present invention, Figure 2 As shown, an inclined portion 111 is provided inside the ventilation cavity 102, and the inclined portion 111 is inclined downward from the drainage channel 110 to the water diversion channel 107. Through such a configuration, it is ensured that rainwater and accumulated water can flow smoothly to the water diversion channel 107 and then enter the drainage channel 110, thereby preventing rainwater and accumulated water from accumulating in the ventilation cavity 102, thereby maintaining the smooth flow of the ventilation system and avoiding blockage and failure of the ventilation system due to accumulated water.

[0024] In one embodiment of the present invention, Figure 1 and Figure 5 As shown, a filter screen II 113 is installed at the water outlet of the drain pipe 112. This arrangement can prevent large particles or other impurities from entering the drain pipe 112, keep the drainage system unobstructed, and reduce drainage problems caused by impurity blockage.

[0025] In one embodiment of the present invention, Figure 2 As shown, the water inlet groove 109 and the water diversion groove 108 are the same width as the water storage cavity 105. Through such an arrangement, it is ensured that water can smoothly flow into the water storage cavity 105, and enter the Tesla valve structure flow channel 106 through the water diversion groove 108 and the water inlet groove 109. Due to the same width, the water flow will not be restricted or hindered, ensuring the effectiveness and smoothness of the ventilation system during drainage on rainy days, and preventing water accumulation and blockage.

[0026] In one embodiment of the present invention, Figure 1 As shown, four mounting members 103 are symmetrically mounted on the bottom of the frame 100. This arrangement ensures the stability and balance of the frame 100, so that the ventilation equipment can be stably installed and supported inside the coal shed.

[0027] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
