Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, and in particular to a drainage device for mine water control. Background Technology

[0002] Water control and drainage devices are important facilities used in underground engineering projects such as mines to divert and discharge groundwater. During the mining process, coal mines often experience significant seepage water or rainy weather, necessitating timely drainage of the water. Traditional water control and drainage devices typically use water pumps to remove the water. To address this, a Chinese utility model patent (publication number: CN220319618U) has been granted, proposing an emergency drainage device for coal mines. This device filters the water in the roadway through a housing, and then a drainage pump discharges the water from the housing, preventing impurities from clogging the drainage pump.

[0003] When the water level in the tunnel is high, the water only enters the main body of the box through the filter hole, resulting in a slow drainage speed. At this time, removing the baffle allows the water to enter the second filter chamber through both the inlet and the filter hole, thus accelerating the drainage efficiency. However, while opening the baffle can speed up the drainage, particulate matter and sediment in the water will also enter the main body of the box. During the subsequent cleaning process, workers need to clean the impurities inside the main body of the box. This cleaning method is relatively inefficient and increases the labor intensity and inconvenience of cleaning. Therefore, a drainage device for mine water control is proposed to address the above situation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where workers need to clean impurities inside the box body during the subsequent cleaning process. This cleaning method is relatively inefficient and increases the labor intensity and inconvenience of cleaning. Therefore, this invention proposes a drainage device for mine water control.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drainage device for mine water control includes a box body with a cavity through the middle of the top of the box body. A box body base is rotatably connected to the bottom of the box body at the cavity. Mounting blocks are fixed on both sides of the cavity body, and a filter screen is detachably installed on both mounting blocks. A drive assembly is fixed on both sides of the outside of the box body, and the bottom end of the drive assembly is connected to one side of the box body base.

[0007] The driving component includes a fixed plate, a mounting housing, an electric push rod, a mounting component, an extension rod and a mounting seat. The fixed plate is fixed at one end of the top of the box body, and a mounting housing is fixed on one side of the fixed plate. An electric push rod is rotatably connected inside the mounting housing. The moving end of the electric push rod is fixed with an extension rod, and one end of the extension rod is rotatably connected with a mounting seat. One end of the mounting seat is fixed on one side of the base of the box body.

[0008] Preferably, a clamping groove is formed at the top of the mounting block, and one end of the filter net is clamped in the clamping groove.

[0009] Preferably, an installation cavity is formed at the bottom of the mounting housing, and gaps communicating with the installation cavity are formed through both sides of the outside of the mounting housing.

[0010] Preferably, mounting components are fixedly arranged on both sides inside the mounting housing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A drainage device for mine water control includes a housing 1. The main structural difference between the housing 1 and existing technologies (publication number: CN220319618U) is the addition of a housing base 5 and a drive assembly 4. The pumping equipment on the housing 1 and its operation are the same as in existing technologies, and will not be elaborated further. Furthermore, to ensure the tilt angle of the housing base 5, support rods can be installed at the four corners of the bottom of the housing 1 to raise the housing 1. These support rods can also be replaced by cylinders, which are installed outside the housing 1. The piston rod of the cylinder is connected to the base plate, and the operation of the cylinder lowers the base plate, thus raising the housing 1 upon contact with the ground. The height of the box 1 can be freely controlled. A cavity 101 is opened through the middle of the top of the box 1. The bottom of the box 1 is rotatably connected to the box base 5 at the cavity 101. Mounting blocks 2 are fixed on both sides inside the cavity 101. A filter screen 3 is detachably installed on both mounting blocks 2. A slot is opened on the top of the mounting block 2. One end of the filter screen 3 is locked in the slot. Furthermore, the filter screen 3 is installed on the mounting block 2 by mounting on the frame. The bottom of the frame has a protrusion that contacts the top surface of the box base 5. A drive assembly 4 is fixed on both sides outside the box 1. The bottom end of the drive assembly 4 is connected to one side of the box base 5.

[0022] The driving component 4 includes a fixing plate 401, a mounting housing 402, an electric push rod 403, a mounting component 404, an extension rod 405 and a mounting seat 406. The fixing plate 401 is fixed at one end of the top of the box body 1, and a mounting housing 402 is fixed on one side of the fixing plate 401. An electric push rod 403 is rotatably connected inside the mounting housing 402. An installation cavity is formed at the bottom of the mounting housing 402, and gaps 407 communicating with the installation cavity are respectively formed through both sides of the outside of the mounting housing 402. Two mounting components 404 are commonly fixed on both sides inside the mounting housing 402. The mounting component 404 includes two rectangular plate bodies respectively mounted on both sides inside the mounting housing 402 and a short shaft rotatable between the two plate bodies. One side of the electric push rod 403 away from the moving end is fixed on the short shaft. An extension rod 405 is fixed to the moving end of the electric push rod 403, and a mounting seat 406 is rotatably connected to one end of the extension rod 405. Another mounting component 404 is fixed on the top of the mounting seat 406. The bottom end of the extension rod 405 is connected to the mounting component 404. One end of the mounting seat 406 is fixed on one side of the box body base 5. The top surface of the box body base 5 is in a "mouth" shape and is embedded with a rubber sealing pad. The rubber sealing pad can enhance the sealing performance and prevent sewage from seeping in at the connection between the box body base 5 and the box body 1, thus causing the preliminary filtering effect to fail.

[0023] The usage method and advantages of the present utility model: When this kind of drainage device for preventing and controlling water in mines is in use, the working process is as follows:

[0024] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, when using this device, first, an external power supply and a switch are connected to the electrical equipment in this device, and the whole device is used for mine drainage operations in the same way as in the prior art (publication number: CN220319618U). When it is necessary to clean the sundries inside the box body 1 after the drainage operation is completed, the staff only needs to turn on the switch of the electric push rod 403 to make it work. The electric push rod 403 works to push the extension rod 405 to descend. The extension rod 405 descends to push the mounting seat 406 to descend, thereby causing the box body base 5 to rotate, so that the impurities on the surface of the box body base 5 can quickly fall off, achieving the advantages of faster cleaning efficiency, reducing the cleaning difficulty of the staff and reducing the workload.

[0025] Moreover, through the design of the mounting block 2 and the card slots opened on the mounting block 2, during the subsequent cleaning process of the equipment, the filter net 3 is taken out from inside the mounting block 2 for cleaning and replacement to ensure the filtering effect of the filter net 3. And cleaning outside the box body 1 is more convenient than cleaning inside the box body 1.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
