Description

Technical Field

[0001] This utility model relates to the field of labeling device technology, and in particular to a washable layered labeling device. Background Technology

[0002] A stratified marker is a device for monitoring ground settlement. The marker base is a key component that transmits minute deformations of ground settlement to ground monitoring instruments via an internal marker, collecting ground settlement monitoring data.

[0003] An existing layered marker assembly with a telescopic protective tube has a solid inner rod. In actual work, there is often sediment at the bottom of the borehole, and the marker cannot be placed at the designed target layer. All the marker rods of the layered assembly must be removed, and then the drill rod must be lowered in and the pump flow rate increased to punch the hole, which is very inefficient. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rinsing device for the bottom of the stratified marker, which overcomes the shortcomings of the prior art and effectively solves the problems of repeated drilling and rinsing of sediment, which is time-consuming, labor-intensive and inefficient.

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

[0006] A washable layered marker bottom device includes an insert rod, an inner marker rod welded and fixed to the top of the insert rod, and a tray slidably connected to the bottom of the outer wall of the inner marker rod. An outer protective tube is welded and fixed to the top of the tray, and a collar is sleeved and fixed to the top of the outer wall of the outer protective tube. Adjusting screws are welded and fixed to both sides of the top of the collar, and the two adjusting screws are respectively connected to limit rings. An inner marker bottom tube is slidably connected to the inner wall of the limit ring, and a slip ring is welded and fixed to the bottom of the inner marker bottom tube. A return connector is inserted into the top of both the inner marker bottom tube and the inner marker rod, and a backstop assembly is fixed to the bottom of the inner marker rod. The backstop assembly includes a fixed ring, a fixed frame welded and fixed to the bottom of the fixed ring, a movable rod inserted and movable at the center of the fixed frame, a piston welded and fixed to the top of the movable rod, and a telescopic spring disposed between the piston and the fixed frame and sleeved on the wall of the movable rod.

[0007] By inserting the top of the external connector into the return connector, the flushing fluid enters the inner indicator rod. When the water flows through the check valve assembly, the water pressure pushes the piston downward. Combined with the contraction of the telescopic spring, the piston moves downward away from the fixed ring, thereby opening the flushing channel. This allows the flushing fluid to be injected directly into the bottom of the hole through the inside of the inner indicator rod. When the water flow below pushes the piston, the piston will block the bottom of the fixed ring, thus preventing the flushing fluid from flowing back.

[0008] Preferably, the inner marker is a hollow structure, and the top of the tray has a through hole that matches the outer diameter of the inner marker.

[0009] By designing the inner marker as a hollow structure, the flushing fluid can be directly injected into the bottom of the hole through the inside of the inner marker, providing a stable flushing fluid channel.

[0010] Preferably, the top two sides of the limiting ring are respectively provided with insertion holes, and the insertion holes are connected to the adjusting screw.

[0011] The position of the limit ring can be adjusted up and down along the adjusting screw.

[0012] Preferably, the adjusting screw is screwed with a locking nut, and the adjusting screw and the limiting ring are limited and fixed by the locking nut.

[0013] By rotating the locking nut, the position of the locking nut on the adjusting screw is adjusted, thereby supporting the bottom of the limiting ring.

[0014] Preferably, the outer diameter of the slip ring is adapted to the inner diameter of the outer protective tube, and the inner diameter of the slip ring is adapted to the outer diameter of the inner marker.

[0015] The downward insertion position of the inner tube of the standard base is limited and blocked by the set slip ring.

[0016] Preferably, the outer annular wall of the fixing ring is welded and fixed to the inner wall of the inner marker rod, and a sealing fit is formed between the fixing ring and the piston.

[0017] When the flushing fluid enters the inner gauge rod, the water flow pushes the piston downwards. Combined with the contraction of the telescopic spring, the piston moves downwards away from the fixed ring, thereby opening the flushing channel. When the water flow below pushes the piston, the piston will block the bottom of the fixed ring, thus preventing the flushing fluid from flowing back.

[0018] The beneficial effects of this utility model are as follows:

[0019] By designing the inner marker rod as a hollow structure and adding a check valve component at the bottom, the flushing fluid can be directly injected into the bottom of the hole through the inside of the inner marker rod, providing a stable flushing fluid channel. This effectively solves the problem of repeated drilling and flushing of sediment in existing technologies, which is time-consuming, labor-intensive, and inefficient. Attached Figure Description

[0024] 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.

[0025] Example:

[0026] Reference Figure 1-3 A washable layered label bottom device includes a stub 1, an inner label rod 2 welded and fixed to the top of the stub 1, a tray 3 slidably connected to the bottom of the outer wall of the inner label rod 2, an outer protective tube 4 welded and fixed to the top of the tray 3, a collar 5 sleeved and fixed to the top of the outer wall of the outer protective tube 4, adjusting screws 6 welded and fixed to the top of the collar 5 on both sides respectively, the two adjusting screws 6 are respectively connected to limit rings 8, the inner wall of the limit ring 8 is slidably connected to the label bottom inner tube 9, a slip ring 10 welded and fixed to the bottom of the label bottom inner tube 9, a return connector 11 inserted into the top of the label bottom inner tube 9 and the inner label rod 2, and a flow-stopping component 12 fixed to the bottom of the inner label rod 2. The flow-stopping component 12 includes a fixed ring 13, a fixed frame 14 welded and fixed to the bottom of the fixed ring 13, a movable rod 15 inserted and movable at the center of the fixed frame 14, a piston 16 welded and fixed to the top of the movable rod 15, and a telescopic spring 17 set between the piston 16 and the fixed frame 14 and sleeved on the rod wall of the movable rod 15.

[0027] The inner indicator rod 2 has a hollow structure, and the top of the tray 3 has a through hole that matches the outer diameter of the inner indicator rod 2. By designing the inner indicator rod as a hollow structure, the flushing fluid can be directly injected into the bottom of the hole through the inside of the inner indicator rod, providing a stable flushing fluid channel. The top two sides of the limiting ring 8 have insertion holes, which are connected to the adjusting screw 6. The limiting ring 8 can be adjusted up and down along the adjusting screw 6. The adjusting screw 6 is screwed with a locking nut 7. The adjusting screw 6 and the limiting ring 8 are fixed by the locking nut 7. By rotating the locking nut 7, the position of the locking nut 7 on the adjusting screw 6 is adjusted, thereby supporting the bottom of the limiting ring 8.

[0028] The outer diameter of the slip ring 10 is matched with the inner diameter of the outer protective tube 4, and the inner diameter of the slip ring 10 is matched with the outer diameter of the inner marker 2. The slip ring 10 limits and blocks the downward insertion of the inner tube 9 of the marker bottom. The annular outer wall of the fixed ring 13 is welded and fixed to the inner wall of the inner marker 2. A sealing fit is formed between the fixed ring 13 and the piston 16. When the flushing fluid enters the inner marker 2, the water flow pushes the piston 16 downward. With the contraction of the telescopic spring 17, the piston 16 moves downward away from the fixed ring 13, thereby opening the flushing channel. When the water flow below pushes the piston 16, the piston 16 will block the bottom of the fixed ring 13, thereby preventing the flushing fluid from flowing back.

[0029] Working principle:

[0030] During operation, the flushing fluid enters the inner gauge rod 2 by inserting the external connector into the top of the return connector 11. When the water flows through the check valve assembly 12, the water pressure pushes the piston 16 downward. With the contraction of the telescopic spring 17, the piston 16 moves downward away from the fixed ring 13, thereby opening the flushing channel. This enables the flushing fluid to be injected directly into the bottom of the hole through the inner gauge rod. When the water flow below pushes the piston 16, the piston 16 will block the bottom of the fixed ring 13, thus preventing the flushing fluid from flowing back.

[0031] 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.
