Description

A coal mine roadway roof drainage device Technical Field

[0001] This utility model relates to the technical field of coal mine roadway diversion devices, specifically to a coal mine roadway roof diversion device. Background Technology

[0002] As coal mining years increase, mining depths rise, and the number of interchanges in coal mines grows, the accumulation of water in goaf areas and groundwater increases. When coal mine roadways intersect above closed roadways or goaf areas, water accumulated in the roof anchor bolts or cables flows downwards along the gaps, forming a water-soaked area. This roof water, in prolonged contact with air and water pipes and electrical equipment, leads to pipe corrosion and equipment aging. Miners exposed to this water for extended periods become damp, susceptible to illness, and face increased safety hazards.

[0003] The existing construction accessories for water spraying on the roof of coal mine roadways are too complicated, making it impossible to divert water from a large area in a unified manner. Furthermore, they cannot effectively assess the silt accumulation in the water collection troughs, requiring workers to climb up and inspect each section individually, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this utility model is to provide a drainage device for the roof of a coal mine roadway. This device is easy to install, simple to operate, has a simple structure, high water drainage efficiency, and can promptly reflect the siltation situation in the water accumulation tank.

[0005] This utility model includes a water collection trough covering the water-sprinkling area of ​​the tunnel roof. The water collection trough is an open trough with a bottom plate at the bottom, side plates around the perimeter, and an open top. One of the side plates of the water collection trough has a drain outlet that penetrates the surface of the side plate, and the drain outlet is connected to a drainage pipe.

[0006] Preferably, there are at least two drain outlets, which are arranged vertically on the same side plate with a gap between them, and the drain pipe is connected to the lower drain outlet.

[0007] Preferably, the side plate of the water collection tank is fixedly connected with hanging ears at intervals, and the hanging ears are provided with through holes, through which hanging rings for suspending the water collection tank are inserted.

[0008] Preferably, there are no fewer than four hanging ears, which are evenly distributed on each side plate of the water collection tank.

[0009] Preferably, the number of hanging ears on the side plate opposite the drain outlet is greater than the number of hanging ears on the side plate where the drain outlet is located, and the length of the hanging ring inserted on the hanging ear on the side plate opposite the drain outlet is shorter than the length of the hanging ring in other positions.

[0010] Preferably, the drainage tube is made of a flexible tube.

[0011] Preferably, the water collection tank is made of stainless steel.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This device has a simple structure, is easy to install and operate, and can effectively divert water from the top of the roadway to a sedimentation tank or ditch. It has high water diversion efficiency and avoids water from the roadway causing pipeline corrosion, aging of electrical equipment, and long-term contact with water, which can lead to dampness, illness, and increased safety hazards for miners. At the same time, the device can promptly detect the silt in the water accumulation tank, eliminating the need for workers to climb to check, saving time and effort. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] The orientations mentioned in this specification are based on the orientation of the coal mine roadway roof diversion device of this utility model when it is working normally. They do not limit the orientation during storage and transportation, and only represent relative positional relationships, not absolute positional relationships.

[0020] Example 1:

[0021] As shown in Figures 1 and 2, a coal mine roadway roof drainage device includes a water collection trough 1 covering the water-spraying area of ​​the roadway roof. The water collection trough 1 is an open trough with a bottom plate at the bottom, side plates around the perimeter, and an open top. The water collection trough 1 is used to collect water flowing down from various gaps in the roadway roof to prevent pipe corrosion and electrical equipment aging caused by water spraying. One of the side plates of the water collection trough 1 has a drain outlet 2 that penetrates the surface of the side plate. The drain outlet 2 is connected to a drainage pipe 3. The other end of the drainage pipe 3 is placed in a nearby sedimentation tank or ditch to discharge the sewage in the water collection trough 1.

[0022] Furthermore, there are at least two drain outlets 2, arranged vertically on the same side plate. The lower drain outlet 2 is located near the bottom of the water collection tank 1, and the upper drain outlet 2 is located near the top of the water collection tank 1. The drain pipe 3 is connected to the lower drain outlet 2. When sludge accumulates in the water collection tank 1, it will block the lower drain outlet 2, preventing the sewage in the water collection tank 1 from being discharged and causing the water level to gradually rise. When workers find water being discharged from the upper drain outlet 2, it will alert them that there is too much sludge accumulated in the water collection tank 1 and it needs to be cleaned.

[0023] Furthermore, at least four hanging ears 4 are fixedly connected to the side plates of the water collection trough 1 at intervals. These hanging ears 4 are evenly distributed on each side plate of the water collection trough 1. Each hanging ear 4 has a through hole, through which a hanging ring 5 for suspending the water collection trough 1 is inserted. One end of the hanging ring 5 is connected to the hanging ear 4 on the water collection trough 1, and then connected to the hanging ring 5 through a mine-use open-type connecting chain ring, and then connected to the coal mine roof anchor. The drainage outlet 2 located below is connected to one end of the diversion pipe 3 through a strip. The diversion pipe 3 is fixed to the top of the roadway according to the shape of the roadway. The other end of the diversion pipe 3 is placed in a sedimentation tank or ditch near the roadway, thus completing the installation of the diversion device.

[0024] Furthermore, the drainage pipe 3 is made of flexible tubing, which makes installation and wiring more flexible and easier to fix; the water collection tank 1 is made of stainless steel to prevent it from rusting and corroding.

[0025] Example 2:

[0026] The difference between this embodiment and embodiment one is that, as shown in Figure 3, the number of hanging ears 4 on the side plate opposite to the drain outlet 2 is greater than the number of hanging ears 4 on the side plate where the drain outlet 2 is located, and the length of the hanging rings 5 ​​inserted on the hanging ears 4 on the side plate opposite to the drain outlet 2 is shorter than the length of the hanging rings 5 ​​in other positions. When installing the drainage device, more hanging rings 5 ​​are suspended on the side plate opposite to the drain outlet 2, and the length of the hanging rings 5 ​​on this side plate is slightly shorter than the length of the hanging rings 5 ​​in other positions, so that the water collection tank 1 is tilted towards the drain outlet 2, which facilitates the drainage of water in the water collection tank 1.

[0027] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
