Description

Technical Field

[0001] This utility model relates to the field of fracture zone height measurement technology, and in particular to a fracture zone height measurement device. Background Technology

[0002] Water-conducting fracture zones are formed by rock fracturing caused by tectonic, diagenetic, and weathering processes, which increases permeability and often allows groundwater to accumulate or becomes a channel for groundwater flow. The water conductivity of a water-conducting fracture zone depends on the lithology, scale, mechanical properties of the fracture, the hydraulic connection between the fracture zone and the aquifer or surface water body, and the topographic features of the location. A fracture zone with good water conductivity is a good water-conducting channel and also a channel for water inrush in mines and tunnels. It is necessary to detect water-conducting fracture zones when they are discovered.

[0003] The existing patent (publication number: CN221838317U) discloses that "this utility model relates to the technical field of water-conducting fracture zone detection device, specifically a water-conducting fracture zone detection device for coal mine goaf, including a supporting base plate, a device frame fixedly installed on the top of the supporting base plate, and a drill rod assembly provided on one side of the device frame. This coal mine goaf water-conducting fracture zone detection device, by installing the drill rod assembly, can achieve the adjustment of the support plate with the extended drill rod to a suitable drilling height through the cooperation between the drill chamber and the telescopic rod, etc. Then, when the extended drill rod enters the wall, the water flow will reach multiple expansion capsules from inside the extended drill rod. When a certain water pressure value is reached, the water flow will be discharged from the outlet channel into the water-conducting fracture, and the change in water pressure is detected. Moreover, through the water pressure converter, multiple rock strata can be measured. The expansion capsules also achieve integrated sealing of side leakage, thereby avoiding drill rod entanglement and the need for frequent movement."

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: Although the device can prevent the drill rod from getting tangled and needing to be moved frequently during use, it is inconvenient to disassemble the drill rod periodically for replacement or maintenance.

[0005] Therefore, this application provides a fracture zone height measuring device to solve the problems mentioned in the background art. Utility Model Content

A lead screw 118 is fixedly disposed between the two gears 108. A third fixing block 117 is threaded around the lead screw 118. A connecting rope 107 is connected between the third fixing block 117 and the snap-fit ​​block 106.

[0030] Specifically, starting the second electric push rod 112 moves the fixing plate 116 upward, which in turn moves the two racks 111 upward. The two racks 111 rotate the two gears 108, which in turn rotate the lead screw 118. The lead screw 118 moves the third fixing block 117, which pulls the connecting rope 107 to disengage the locking block 106 from the fixing assembly 103, facilitating the upward movement of the fixing assembly 103. The second electric push rod 112 continues to move the fixing plate 116 upward, which in turn moves the fixing ring 114 upward. The fixing ring 114 moves the fixing assembly 103 upward, facilitating the removal of the drill rod assembly 8 inside the fixing assembly 103 for replacement and maintenance. The spring 105 helps to push the locking block 106 to fix the fixing assembly 103. The two first fixing blocks 109 facilitate the installation of the two gears 108.

The two racks 111 mesh with the two gears 108 respectively.

[0032] Specifically, the support frame 110 facilitates the installation of two second fixing blocks 113, which in turn limit the connection rope 107 and allow the third fixing block 117 to drive the snap block 106 to disengage from the fixing component 103 via the connection rope 107; the two connecting rods 104 allow the two racks 111 to simultaneously drive multiple gears 108 to rotate; and the two connecting plates 102 allow the second electric push rod 112 to simultaneously push the three fixing components 103 upward.

[0033] Working principle: When in use, the device activates the second electric push rod 112, which moves the fixed plate 116 upward. The fixed plate 116 moves the two racks 111 upward, which in turn rotate the two gears 108. The two gears 108 rotate the lead screw 118, which in turn moves the third fixed block 117. The third fixed block 117 pulls the connecting rope 107, causing the locking block 106 to disengage from the fixed assembly 103. Then, the second electric push rod 112 continues to move the fixed ring 114, which in turn moves the fixed assembly 103 upward. This facilitates the removal of the drill rod assembly 8, making it easier to maintain and replace.
