Description

Technical Field

[0001] The utility model relates to the field of construction equipment, and is a gravity water seepage device for a full-rotation drilling rig. Background Art

[0002] A full-rotation drilling rig utilizes the rotary torque and axial pressure of the pipe body to remove rock and soil debris crushed by the drill bit from the ground. Its structure primarily consists of the drill body, full casing, drill bit, transmission system, hydraulic system, and electrical system. The drill body is the supporting framework for the entire device, the full casing is the primary soil-feeding component, the drill bit is used to crush the soil, the transmission system drives the drill bit's rotation, the hydraulics provide power, and the electrical system controls the device's operating speed and pressure. When the casing is filled with soil and obstacles, a grab bucket can be used to remove these materials to ensure smooth drilling. However, in actual construction, it has been found that certain geological conditions contain large amounts of groundwater, making it difficult for the grab bucket to achieve optimal gripping operations. This makes it difficult to remove soil and obstacles from the casing, which is time-consuming and labor-intensive, impacting construction efficiency and schedule. The current method of removing water from the casing is to use a seepage bucket. This involves hoisting the seepage bucket into the casing, using its own weight to squeeze the water through the gaps in the casing wall and into the bucket. The bucket is then hoisted out for disposal. However, this method suffers from a lack of visibility into the water depth within the casing during the seepage operation. When dealing with large amounts of water, multiple seepage operations are often required, resulting in a time-consuming and inefficient process. Therefore, improvements are needed to existing seepage devices for fully rotary drilling rigs. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the present invention aims to provide a gravity-assisted watering device for a fully rotary drilling rig. This device addresses the technical problems of existing similar watering devices, such as their relatively simple structure and dimensions, inability to adjust the watering volume, time-consuming and labor-intensive construction, and low efficiency. This objective is achieved through the following technical solution.

[0004] A gravity-driven weeping device for a full-rotation drilling rig, the main body of which is a weeping barrel. The barrel comprises an upper barrel and a lower barrel that are telescopically engaged. The lower barrel is closed at the bottom, while the upper barrel communicates with the lower barrel and has an open top. A telescopic water bucket is located within both the upper and lower barrels, with the top of the bucket fixed to the top of the upper barrel. A lifting lug is fixed to the top of the upper barrel. Initially, the upper barrel is retracted relative to the lower barrel under the action of gravity. When the upper barrel is lifted, the upper barrel extends and opens relative to the lower barrel under the action of the gravity of the lower barrel. The bucket is initially retracted, but expands in response to water overflow. This structure allows the weeping barrel's height and capacity to adapt to changes in length as it expands, resulting in a greater weeping capacity than existing single-size weeping barrels. This effectively reduces the number of weeping operations and improves construction efficiency.

[0005] The circumference of the upper cylinder is provided with a vertical limiting sliding hole, and the circumference of the lower cylinder is connected with a limiting sliding block that cooperates with the limiting sliding hole. Through this structure, the telescopic limiting cooperation between the upper cylinder and the lower cylinder is achieved, and the structural connection is more convenient and reliable.

[0006] The top of the upper cylinder is fixed to the top of the water bucket by a bolt with a lifting lug. By this structure, while the upper cylinder is conveniently fixed to the water bucket, the lifting lug structure of the bolt can also be directly used for lifting.

[0007] The bottom of the water bucket is fixed to the bottom surface of the lower cylinder, that is, the water bucket deforms with the expansion and contraction of the upper and lower cylinders. Through this structure, the water bucket can be adjusted synchronously with the expansion and contraction of the upper and lower cylinders, and the deformation of the bucket is more reliable and stable.

[0008] Several intermediate cylinders are added between the upper and lower cylinders, and the intermediate cylinders form telescopic limit fits between the intermediate cylinders and the upper cylinder, between the intermediate cylinders and the lower cylinder, and between adjacent intermediate cylinders. The water bucket is located within the upper, intermediate, and lower cylinders. This structure facilitates further achieving different water seepage heights.

[0009] The bottom of the lower cylinder is formed into a round head or a cone head shape. Through this structure, it is convenient for the lower cylinder to enter the bottom soil in the sleeve more easily, which is conducive to overflow operation.

[0010] The bottom of the lower cylinder is connected to a detachable end cap. Through this structure, it is convenient to remove the end cap and clean the inside of the lower cylinder.

[0011] The bottom of the lower cylinder is provided with a drain with a plug. Through this structure, when needed, by removing the plug, it is convenient for the water in the lower cylinder to flow out.

[0012] The overall structure of the utility model is relatively compact and reasonable. The water seepage cylinder is changed to a telescopic structure, which is convenient for adjusting the water seepage height and water seepage capacity. The water seepage operation is relatively convenient and efficient, which reduces the construction workload and improves the construction efficiency. It is suitable for use as a gravity water seepage device in conjunction with a full-rotation drilling rig, or as a structural improvement of similar water seepage devices.

[0020] The present invention will now be further described with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, the main body of the weeping device is a weeping cylinder. The weeping cylinder comprises an upper cylinder 1 and a lower cylinder 2, which are arranged to telescopically limit the movement of the cylinder. The upper cylinder is provided with a vertical limit slide hole 101 on its circumference, and the lower cylinder is bolted to a limit slide 201 that fits within the limit slide hole. The bottom of the lower cylinder is closed, while the upper and lower cylinders are connected. The top of the upper cylinder is open, and a deformable water bucket 3 made of deformable plastic or rubber is installed within each cylinder. The top of the water bucket is secured to the top of the upper cylinder by evenly spaced bolts 4, which are integrated with lifting lugs 401 for easy lifting. Initially, the upper cylinder is retracted relative to the lower cylinder under the action of gravity, extending into the upper cylinder. When the upper cylinder is lifted, the gravity of the lower cylinder causes the upper cylinder to extend and open relative to the lower cylinder. The bucket is initially in a contracted state. When water overflows into the bucket, the bucket adapts to the weight of the water and extends. When the upper cylinder is fully extended and opened relative to the lower cylinder, the maximum extension state of the bucket is when it contacts the bottom surface of the lower cylinder, at which time the maximum water secretion capacity is reached.

[0022] The bottom of the water bucket 3 can also be fixed to the bottom surface of the lower cylinder 2, that is, the water bucket forms a synchronous telescopic deformation when the upper cylinder 1 and the lower cylinder are expanded and contracted.

[0023] Furthermore, a number of intermediate cylinders can be added between the upper cylinder 1 and the lower cylinder 2. The same telescopic limit fit between the upper cylinder and the lower cylinder is formed between the intermediate cylinder and the upper cylinder, between the intermediate cylinder and the lower cylinder, and between adjacent intermediate cylinders. The water bucket 3 is located in the upper cylinder, the intermediate cylinder, and the lower cylinder.

[0024] Furthermore, if Figure 5 As shown, the bottom of the lower cylinder 2 is formed into a round head or a cone head shape.

[0025] Furthermore, the closed structure at the bottom of the lower cylinder 2 is also replaced by a detachable end cover.

[0026] Furthermore, a drain outlet with a plug may also be provided at the bottom of the lower cylinder 2 .

[0027] like Figure 5 、 Figure 6As shown, the method for using the water seepage device is as follows: the entire device is hoisted into the casing hole of a fully rotary drilling rig using a crane. The device, under its own weight, is then lowered into the casing hole bottom until the upper cylinder 1 contracts into position relative to the lower cylinder 2. At this point, the water in the casing overflows into the water bucket 3 of the device under the force of the device's gravity. When the amount of water is large and exceeds the current water seepage capacity of the water bucket, the lower cylinder maintains contact with the casing bottom under the action of its own weight as the crane is lifted. The upper cylinder extends relative to the lower cylinder as the crane is lifted. During this process, the water bucket adaptively deforms, increasing its water seepage capacity. Water continues to overflow into the water bucket until the upper cylinder is fully extended relative to the lower cylinder, i.e., the bucket reaches its maximum water seepage capacity. Finally, the entire device is lifted out by the crane, and the water bucket is dumped to drain the water, completing the water seepage operation.

[0028] The above content is intended to illustrate the technical means of the present invention and is not intended to limit the technical scope of the present invention. Those skilled in the art who, in combination with existing common knowledge, make obvious improvements or substitutions to the present invention also fall within the scope of protection of the claims of the present invention.
