Description

Technical Field

[0001] This utility model relates to the field of water-conducting fracture zone detection technology, and in particular to a device for detecting water-conducting fracture zones in coal mine goaf areas. Background Technology

[0002] A coal mine goaf refers to the void left after the coal seam below the working face is mined during the coal mining process. Due to mining activities and other reasons, water-conducting fracture zones may form near the goaf. When groundwater flows through these fracture zones, it can flow into the coal mine, affecting normal mine production. Therefore, it is necessary to detect the water-conducting fracture zones in coal mine goafs.

[0003] Chinese patent discloses a device for detecting water-conducting fracture zones in coal mine goafs (publication number CN221838317U). This patented technology, through the installation of a drill rod assembly, allows the use of the drill housing and telescopic rod to adjust the support plate with the extended drill rod to a suitable drilling height. Then, when the extended drill rod enters the wall, water flows from inside the extended drill rod to multiple expansion capsules. When a certain water pressure value is reached, the water flows out from the outlet channel into the water-conducting fracture. The device detects the water pressure changes and, through a water pressure converter, can measure multiple rock strata. The expansion capsules also achieve integrated sealing of side leakage, thus avoiding drill rod entanglement and the need for frequent movement.

[0004] However, most existing methods for detecting water-conducting fracture zones only allow adjustment of the drill rod height, not its angle. This makes them unsuitable for detection in different locations. For example, the aforementioned comparative document only uses height adjustment. In practical applications, since the location of water-conducting fracture zones in coal mine goafs varies, height adjustment alone is insufficient for detection in different locations, resulting in low practicality. Therefore, those skilled in the art have provided a device for detecting water-conducting fracture zones in coal mine goafs to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution for a coal mine goaf water-conducting fracture zone detection device: it includes a movable base 1 and a detection water tank 2 and a control cabinet 3 arranged from left to right on the upper surface of the movable base 1. A first electric lifting rod 51 is symmetrically arranged on the lower surface of the movable base 1. The telescopic end of the first electric lifting rod 51 is connected to a stabilizing plate 5. A drying trough is opened on one side of the control cabinet 3. A placement frame 4 is slidably installed inside the drying trough. A placement plate 41 is arranged inside the placement frame 4. This arrangement uses the placement plate 41 inside the placement frame 4 to place and dry the tools used for detection, thereby improving their service life.

[0026] A flexible hose 7 is connected through the upper surface of the detection water tank 2. One end of the flexible hose 7 is connected to an extension drill rod 71. The rear end of the extension drill rod 71 is connected to a water pressure converter 72. The rear end of the water pressure converter 72 is connected to a guide cone 73. A fixed sleeve 6 is provided on the outside of the extension drill rod 71. A movable plate 63 is slidably provided on the upper surface of the movable base 1 behind the detection water tank 2. A rotating disk 62 is rotated on the upper surface of the movable plate 63. The position of the guide cone 73 can be adjusted by moving the movable plate 63. At the same time, the height of the guide cone 73 can be adjusted by the second electric lifting rod 61, and the angle of the guide cone 73 can be adjusted by the rotating disk 62. Thus, the detection work of water-conducting fracture zones in coal mine goaf areas at different locations can be carried out.

[0027] like Figure 4 As shown, the fixed end of the second electric lifting rod 61 is installed on the upper surface of the rotating disk 62, and the telescopic end of the second electric lifting rod 61 is connected to the lower surface of the fixed sleeve 6. This arrangement allows the extension drill rod 71 to be raised and lowered by the operation of the second electric lifting rod 61, so that the height of the guide cone 73 can be adjusted to detect the water-conducting fracture zone at different positions.

[0028] like Figure 1 and Figure 4As shown, an electric telescopic rod 64 is installed on the rear surface of the detection tank 2. The telescopic end of the electric telescopic rod 64 is connected to the front surface of the moving plate 63. A guide plate 65 is provided on the lower surface of the moving plate 63. A guide groove 651 that slides against the guide plate 65 is provided on the upper surface of the moving seat 1. This arrangement allows the moving plate 63 to move on the upper surface of the moving seat 1 by the operation of the electric telescopic rod 64. That is, the guide plate 65 moves within the guide groove 651, thus allowing the guide cone 73 to be moved and inserted into different positions for detection.

[0029] like Figure 4 As shown, a drive motor is also installed inside the movable plate 63. The drive end of the drive motor is connected to a rotating shaft. The upper end of the rotating shaft is on the lower surface of the rotating disk 62. This arrangement uses the operation of the drive motor to make the rotating shaft rotate. When rotating, the rotating disk 62 will rotate to adjust the angle of the guide cone 73, thereby satisfying the detection of different positions.

[0030] like Figure 3 As shown, the upper surface of the detection water tank 2 is provided with a water inlet, and a filter screen 21 is provided inside the detection water tank 2 at the position of the water inlet. The purpose of providing the filter screen 21 at the position of the water inlet inside the detection water tank 2 is to filter the water entering the detection water tank 2.

[0031] like Figure 4 As shown, two first electric lifting rods 51 are symmetrically arranged on the lower surface of the moving base 1. The lower surface of the stabilizing plate 5 is provided with an anti-slip layer. This arrangement utilizes the operation of the first electric lifting rods 51 to raise and lower the stabilizing plate 5, so that the stabilizing plate 5 contacts the ground to ensure the stability of the moving base 1, so as to facilitate its better detection work.

[0032] like Figure 4 As shown, a guide rail 42 is provided on the outer side of the placement frame 4, and a groove is provided on the inner side of the drying tank that slides against the guide rail 42. This arrangement allows the guide rail 42 to move inside the groove, so that the movable plate 63 can move on the movable seat 1 to adjust the position of the guide cone 73 for detecting the water-conducting fracture zone.

[0033] The working principle of this utility model is as follows: When using the coal mine goaf water-conducting fracture zone detection device, water is injected into the detection water tank 2 through the inlet, and the water is filtered through the filter screen 21 during injection. After water injection, the device can be moved to the detection position. Once in position, the device can be controlled through the control cabinet 3. First, the height of the extension drill rod 71 can be raised by the second electric lifting rod 61 to determine the position of the water-conducting fracture zone to be detected. At the same time, the angle of the guide cone 73 can be adjusted by rotating the rotating disk 62. After determining the position, the extension drill rod 71 can be inserted into the wall through the guide cone 73. The water pump in the detection water tank 2 can... Water is drawn through the hose 7 and flows out through the hole on the front surface of the water pressure converter 72 to flow into the water guide slit for detection. For details of the principle, please refer to patent CN221838317U. During detection, the operation of the electric telescopic rod 64 can also move the moving plate 63 on the upper surface of the moving seat 1, that is, the guide plate 65 moves inside the guide groove 651. In this way, the guide cone 73 can be moved to insert into different positions for detection. After the detection contact is made, the hose 7 can be disassembled and placed on the placement plate 41 in the placement frame 4. After placement, it can be sent into the drying tank for drying, thereby improving its service life.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
