Description

Technical Field

[0001] The present application relates to the technical field of water stoppers, and more specifically, to a water stopper for drilling and layered water extraction. Background Art

[0002] Hydrogeological exploration refers to the investigation and research conducted to determine the hydrogeological conditions of a region. Its purpose is to understand the origin, distribution, and movement of groundwater and surface water, providing a basis for the rational exploitation and utilization of water resources and the correct design and construction of foundation and piling projects. During borehole testing, sampling is required, and a water stop is required to seal and isolate the sampling device to improve testing accuracy. Existing water stops are complex in structure, making it difficult to dynamically adjust and secure them during hydrogeological testing, and unable to determine whether the device is level, which increases user inconvenience. Therefore, a water stop for stratified water extraction from a borehole has been proposed. Publication No. CN218439309U discloses a water stop for stratified water extraction from a borehole. While this device addresses the difficulty of disassembling the device for inspection and replacement of parts, it also allows for easy adjustment and securing of the water stop, addressing the inconvenience of use. However, the water stop device for stratified water extraction through drilling has the following disadvantages: (1) The water stop device for stratified water extraction through drilling adopts a movable structure of an adjusting slider, which makes it difficult to accurately and firmly fix the water stop device at a suitable height, resulting in inaccurate force fixation and tipping over and damage of the device; (2) The water stop device for stratified water extraction through drilling lacks a structure for accurately verifying the horizontal state of the device, making it difficult to accurately grasp the on-site sampling angle, resulting in differences in the sampling results.

[0003] The document with the prior art publication number CN220909681U provides a water stop for drilling and layered water pumping. The device, through the arrangement of a disc base, a sleeve rod, bolts, an extension rod and a water stop body, plays a role in dynamically adjusting the height and fixing the device. First, the bolt on one side of the sleeve rod on the disc base is loosened, and then the extension rod is adjusted to a suitable length for use and then tightened to align with the threaded hole on the sleeve rod. Finally, the water stop body connected to the extension rod is also at a suitable height for use, thereby enhancing the adjustability of the device.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device is used for a long time, it will cause blockage of the water inlet cylinder and the filter screen, and if it is not cleaned in time, it will affect the normal water flow effect.

[0005] In view of this, we propose a water stopper for drilling and layered water extraction. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] The purpose of this application is to provide a water stop for drilling and layered water pumping, which solves the technical problems in the above-mentioned background technology, realizes the technical effect of cleaning the water inlet cylinder and filter screen, and ensures normal water flow.

[0008] 2. Technical solution

[0009] The technical solution of the present application provides a water stop for drilling and stratified water pumping, comprising a water stop body, a water inlet cylinder and a filter screen, a cleaning assembly slidingly arranged between the filter screen and the water inlet cylinder, the cleaning assembly comprising an outer ring brush plate for cleaning the outer wall of the filter screen and the inner wall of the water inlet cylinder, an inner ring brush plate for cleaning the inner wall of the filter screen, and a blocking plate for blocking the filter screen and the lower end of the water inlet cylinder, a knocking assembly for intermittently knocking the water inlet cylinder being fixedly mounted on the blocking plate, and a machine room fixing frame for fixing the machine room being fixed on the water inlet cylinder.

[0010] By adopting the above technical solution, the cleaning component is used to make the outer bristles of the inner ring brush plate wipe and clean the inner wall of the filter, the outer bristles of the outer ring brush plate clean the inner wall of the water inlet cylinder, and the inner bristles clean the outer wall of the filter. At the same time, when the inner ring brush plate and the outer ring brush plate are cleaning, the blocking plate moves downward, and the lower ends of the water inlet cylinder and the filter are opened to facilitate the discharge of cleaned debris. At the same time, when the blocking plate descends, the knocking component intermittently knocks the water inlet cylinder, and then under the action of intermittent impact, the vibration transmission causes the debris in the water inlet cylinder and the filter mesh holes to be shaken off, thereby improving the cleaning effect. At the same time, the engine room fixing frame is used to facilitate the fixation of the engine room.

[0011] As an optional solution to the technical solution of this application document, the cleaning component also includes two groups of servo electric cylinders and multiple connecting rods. The cylinder body of the servo electric cylinder is fixed to the outer wall of the water inlet cylinder, the piston rod is fixed to the blocking plate, and the blocking plate is fixedly connected to the outer ring brush plate and the inner ring brush plate through multiple connecting rods.

When the servo electric cylinder extends, the blocking plate is pushed by the piston rod, and the inner ring brush plate and the outer ring brush plate are driven to descend through multiple connecting rods.

[0014] By adopting the above technical solution, when the blocking plate descends, the impact ramp block passes through the spacer block, and the slope surface causes the impact ramp block to support the spring piece to fold outward, and generate an elastic rebound force. When the impact ramp block is separated from the spacer block, the spring piece at this time hits the outer wall of the water inlet cylinder under the action of elastic rebound, thereby knocking the water inlet cylinder, and then when knocking, the debris in the water inlet cylinder and the filter mesh holes can be shaken off.

[0015] As an optional solution to the technical solution of this application document, a waterproof cover is fixed to the outer wall of the water inlet cylinder, the cylinder cover of the servo electric cylinder is arranged in the waterproof cover, and the piston rod passes through the waterproof cover.

[0016] By adopting the above technical solution, the servo electric cylinder is waterproofed by a waterproof cover. At the same time, a wire threading hole is opened on one side of the waterproof cover (not shown in the drawings), and the wire passes through the wire threading hole and is then sealed with sealant.

[0017] As an optional solution to the technical solution of this application document, the blocking plate is a two-cone structure.

[0018] By adopting the above technical solution, the blocking plate is two inverted cone-shaped structures, and the upper cone is adapted to the inner diameter of the lower end of the filter screen, and the lower cone is adapted to the inner diameter of the lower end of the water inlet cylinder, so that the blocking plate can be easily inserted into the water inlet cylinder and the filter screen through the cone.

At the same time, when the inner and outer ring brush plates are cleaning, the blocking plate moves downward, and the lower ends of the water inlet cylinder and the filter are opened to facilitate the discharge of cleaned debris. At the same time, when the blocking plate descends, the knocking component intermittently knocks on the water inlet cylinder, and then under the action of intermittent impact, the vibration transmission causes the debris in the water inlet cylinder and the filter mesh holes to be shaken off, thereby improving the cleaning effect. At the same time, the engine compartment fixing frame is used to facilitate the fixation of the engine compartment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present application is further described in detail below with reference to the accompanying drawings.

[0029] A water stop for drilling and stratified water pumping comprises a water stop body 1, a water inlet cylinder 2 and a filter screen 3, a cleaning assembly 5 is slidingly arranged between the filter screen 3 and the water inlet cylinder 2, the cleaning assembly 5 comprises an outer ring brush plate 54 for cleaning the outer wall of the filter screen 3 and the inner wall of the water inlet cylinder 2, an inner ring brush plate 53 for cleaning the inner wall of the filter screen 3, and a blocking plate 52 for blocking the filter screen 3 and the lower end of the water inlet cylinder 2, a knocking assembly 6 for intermittently knocking the water inlet cylinder 2 is fixedly mounted on the blocking plate 52, and a machine room fixing frame 4 for fixing the machine room is fixed on the water inlet cylinder 2.

[0030] Reference Figure 1-Figure 5 , through the cleaning component 5, the outer bristles of the inner ring brush plate 53 wipe the inner wall of the filter 3, the outer bristles of the outer ring brush plate 54 clean the inner wall of the water inlet cylinder 2, and the inner bristles clean the outer wall of the filter 3. At the same time, when the inner ring brush plate 53 and the outer ring brush plate 54 are cleaning, the blocking plate 52 moves downward, and the lower ends of the water inlet cylinder 2 and the filter 3 are opened to discharge the cleaned debris. At the same time, when the blocking plate 52 descends, the knocking component 6 intermittently knocks the water inlet cylinder 2, and then under the action of intermittent impact, the vibration transmission causes the debris in the holes of the water inlet cylinder 2 and the filter 3 to be shaken off, thereby improving the cleaning effect. At the same time, the engine room fixing frame 4 is used to facilitate the fixation of the engine room.

[0031] The cleaning assembly 5 also includes two groups of servo electric cylinders 51 and multiple connecting rods 55. The cylinder body of the servo electric cylinder 51 is fixed to the outer wall of the water inlet cylinder 2, the piston rod is fixed to the blocking plate 52, and the blocking plate 52 is fixedly connected to the outer ring brush plate 54 and the inner ring brush plate 53 through multiple connecting rods 55.

[0032] Reference Figure 4 and Figure 5 The extension and retraction direction of the piston rod of the servo electric cylinder 51 is parallel to the axis of the filter screen 3 and the water inlet cylinder 2, and when the blocking plate 52 blocks the lower end of the water inlet cylinder 2 and the filter screen 3, the inner ring brush plate 53 and the outer ring brush plate 54 are placed at the upper end of the water inlet cylinder 2 and the filter screen 3, and the servo electric cylinder 51 is in a retracted state at this time, and when the servo electric cylinder 51 extends, the blocking plate 52 is pushed by the piston rod, and the inner ring brush plate 53 and the outer ring brush plate 54 are driven to descend through multiple connecting rods 55.

[0033] The striking assembly 6 includes a spring piece 61 fixed to one side of the blocking plate 52 , an impact slope block 62 fixed to the inner side of the upper end of the spring piece 61 , and a spacer block 63 fixed to the outer wall of the water inlet cylinder 2 at vertical intervals.

[0034] Reference Figure 2 and Figure 5 When the blocking plate 52 descends, the impact slope block 62 passes through the spacer block 63, and the slope surface causes the impact slope block 62 to support the spring piece 61 to fold outward and generate an elastic rebound force. When the impact slope block 62 is separated from the spacer block 63, the spring piece 61 at this time hits the outer wall of the water inlet cylinder 2 under the action of elastic rebound, thereby knocking the water inlet cylinder 2, and then when knocking, the debris in the holes of the water inlet cylinder 2 and the filter screen 3 can be shaken off.

[0035] A waterproof cover 7 is fixed to the outer wall of the water inlet cylinder 2 , the cylinder cover of the servo electric cylinder 51 is arranged in the waterproof cover 7 , and the piston rod passes through the waterproof cover 7 .

[0036] Reference Figure 3 The servo electric cylinder 51 is waterproofed by a waterproof cover 7. At the same time, a wire threading hole (not shown in the drawings) is opened on one side of the waterproof cover 7. The wire passes through the wire threading hole and is then sealed with sealant.

[0037] The blocking plate 52 is a two-cone structure.

[0038] Reference Figure 4 and Figure 5 The blocking plate 52 is two inverted cone-shaped structures, and the upper cone is adapted to the inner diameter of the lower end of the filter screen 3, and the lower cone is adapted to the inner diameter of the lower end of the water inlet cylinder 2, so that the blocking plate 52 can be easily inserted into the water inlet cylinder 2 and the filter screen 3 through the cone.

[0039] Working principle: When in use, the blocking plate 52 blocks the bottom of the water inlet cylinder 2 and the filter screen 3, the servo electric cylinder 51 is in a retracted state, the inner ring brush plate 53 and the outer ring brush plate 54 are placed on the upper end of the water inlet cylinder 2 and the filter screen 3, and the impact ramp 62 is placed on the upper end. When the inner ring brush plate 53 and the outer ring brush plate 54 need to be cleaned, the two servo electric cylinders 51 are started, the piston rod extends, and drives the blocking plate 52 to descend. The blocking plate 52 drives the inner ring brush plate 53 and the outer ring brush plate 54 to descend through multiple connecting rods 55. The impact slope 62 is lowered to wipe and clean the inner wall of the water inlet cylinder 2 and the inner and outer walls of the filter screen 3, and to discharge the debris through the opening at the bottom. At the same time, when the impact slope 62 passes through the spacer 63, the impact slope 62 supports the spring piece 61 to fold outward and generate an elastic rebound force. When the impact slope 62 is separated from the spacer 63, the spring piece 61 at this time hits the outer wall of the water inlet cylinder 2 under the action of elastic rebound, so as to knock the water inlet cylinder 2, so that the debris in the hole is shaken off and discharged through the lower end opening.
