Description

Technical Field

[0001] This utility model relates to the field of drill cuttings collection technology, specifically a drill cuttings collection device. Background Technology

[0002] Currently, common detection methods for predicting rockbursts in coal mines include drill cuttings method, electromagnetic radiation method, and microseismic monitoring method. Since the latter two methods involve high costs and cannot pinpoint specific locations, while the drill cuttings method is simple to implement and easy for workers to master, it plays a significant role in monitoring rockburst areas.

[0003] The drill cuttings method is a method of estimating the stress in a coal face by drilling holes into the coal face and measuring the amount of drill cuttings discharged at different hole depths during the drilling process. In other words, it establishes a quantitative relationship between the amount of drill cuttings and the stress in the coal face, so as to estimate the stress value at a certain point based on the amount of drill cuttings.

[0004] Traditional methods for measuring drill cuttings typically involve inserting a pipe into the coal face, then passing the drill rod through the pipe and pressing it against the coal face to drill. During drilling, a woven bag is tied to the other end of the pipe to collect the drill cuttings. This method is cumbersome, requiring adjustments to the shape of the woven bag to obtain accurate results when weighing the drill cuttings. Furthermore, the drill cuttings adhering to the inside of the woven bag are difficult to clean after weighing.

[0005] Some existing technologies also use a conduit that can be inserted into the borehole to hold the drill rod, and then connect an output pipe to the side wall of the conduit to guide the drill cuttings discharged from the borehole into a collection bag. This method can collect drill cuttings while drilling, making it more efficient. However, some drill cuttings may remain on the conduit between the borehole opening and the output pipe, affecting the accuracy of the amount of drill cuttings collected. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a drill cuttings collection device that can achieve complete collection of drill cuttings and ensure the accuracy of the collected drill cuttings quantity.

[0007] To achieve the above objectives, the specific solution adopted by this utility model is as follows: a drill cuttings collection device, including a guide tube for the drill rod to pass through, a slit extending along the length direction on the guide tube, one end of the slit being close to the first end of the guide tube, and an insertion part that can be inserted into the drill hole being formed on the portion of the guide tube between the slit and the first end, the other end of the slit extending to the second end of the guide tube, and a collection component for collecting drill cuttings being detachably connected to the edge of the slit, the collection component including a collection bag.

[0008] As a further optimization of the above-mentioned drill cuttings collection device: multiple connecting plates are fixedly connected to the edge of the cut, and a soft frame is fixedly connected to the opening of the collection bag. The soft frame is detachably connected to the connecting plates, and the soft frame fits against the edge of the cut when connected to the connecting plates.

[0009] As a further optimization of the above-mentioned cuttings collection device: the connecting plate has connecting holes, and multiple connecting rods are fixedly connected to the inner side of the soft frame. The connecting rods are inserted into the connecting holes to connect the soft frame to the connecting plate.

[0010] As a further optimization of the above-mentioned drill cuttings collection device: the opening of the collection bag is connected to the soft frame through a guide channel, which gradually narrows from top to bottom.

[0011] As a further optimization of the above-mentioned drill cuttings collection device: the soft frame is configured as a rectangular frame, the soft frame includes two first side rods parallel to the guide tube, two second side rods are fixedly connected between the two first side rods, and the connecting rod is fixedly arranged inside the first side rods.

[0012] As a further optimization of the above-mentioned drill cuttings collection device: the opening of the collection bag is fixedly connected to a soft frame, the soft frame is fixedly connected to at least one collar, and the guide tube can pass through the collar to make the soft frame fit against the edge of the cut.

[0013] As a further optimization of the above-mentioned cuttings collection device: multiple collars are provided, and the multiple collars are evenly distributed along the length direction of the guide tube.

[0014] As a further optimization of the above-mentioned drill cuttings collection device: the opening of the collection bag is connected to the soft frame through a guide channel, which gradually narrows from top to bottom.

[0015] As a further optimization of the aforementioned cuttings collection device, the cut is located to the side of the axis of the guide tube.

[0016] Beneficial effects: This utility model makes a cut in the guide tube, with one end of the cut fitting into the borehole and the other end of the cut penetrating the end of the guide tube outside the borehole. Therefore, the drill cuttings falling out of the borehole can fall into the collection bag through the cut, achieving complete collection of drill cuttings and ensuring the accuracy of the amount of drill cuttings collected.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1 As shown, a drill cuttings collection device includes a guide tube 1 through which a drill rod passes. A slit 2 extending along the length direction is provided on the guide tube 1. One end of the slit 2 is close to the first end of the guide tube 1, and the portion of the guide tube 1 between the slit 2 and the first end forms an insertion part 5 that can be inserted into a borehole. The other end of the slit 2 extends to the second end of the guide tube 1. A collection component for collecting drill cuttings is detachably connected to the edge of the slit 2. The collection component includes a collection bag 8.

[0021] During drilling, when the hole depth equals the length of the insertion part 5, the insertion part 5 of the guide tube 1 can be inserted into the hole, and the drill rod can be passed through the guide tube 1 to continue drilling. Drill cuttings generated during drilling fall from the hole opening and then through the cut 2 on the guide tube 1 into the collection bag 8 of the collection assembly, thus completing the collection of drill cuttings. Because one end of the cut 2 is adjacent to the insertion part 5, and the other end of the cut 2 extends to the end of the guide tube 1 outside the hole, the drill cuttings can completely fall into the collection bag 8 through the cut 2 without accumulating inside the guide tube 1. This ensures complete collection of the drill cuttings falling from the hole and guarantees the accuracy of the collected drill cuttings quantity.

[0022] This invention creates a slit 2 on the guide tube 1, with one end of the slit 2 fitting into the borehole and the other end of the slit 2 penetrating the end of the guide tube 1 located outside the borehole. Therefore, all the drill cuttings falling out of the borehole can fall into the collection bag 8 through the slit 2, achieving complete collection of drill cuttings and ensuring the accuracy of the collected drill cuttings quantity.

[0023] Furthermore, the incision 2 is located to the side of the axis of the guide tube 1.

[0024] Two embodiments are provided below regarding the connection method between the guide tube 1 and the collection component.

[0025] Example 1.

[0026] like Figure 2 As shown, multiple connecting plates 3 are fixedly connected to the edge of the cut 2, and a soft frame 6 is fixedly connected to the opening of the collection bag 8. The soft frame 6 and the connecting plates 3 are detachably connected, and when the soft frame 6 and the connecting plates 3 are connected, the soft frame 6 fits against the edge of the cut 2.

[0027] In use, connect the soft frame 6 to the connecting plate 3, and ensure that the soft frame 6 fits against the edge of the cut 2 to close the cut 2. Then, insert the insertion part 5 into the hole to collect drill cuttings.

[0028] Furthermore, such as Figure 3 As shown, the connecting plate 3 has connecting holes 4, and multiple connecting rods 9 are fixedly connected to the inner side of the flexible frame 6. The connecting rods 9 are inserted into the connecting holes 4 to connect the flexible frame 6 to the connecting plate 3. Connecting the flexible frame 6 to the connecting plate 3 is simple; just insert the connecting rods 9 into the connecting holes 4. After collecting the drill cuttings, pull the connecting rods 9 out of the connecting holes 4 to separate the flexible frame 6 from the guide tube 1. It should also be noted that because the flexible frame 6 is flexible, it can be twisted and stretched, ensuring that the connecting rods 9 can be smoothly inserted into and smoothly pulled out of the connecting holes 4.

[0029] like Figure 4 As shown, to ensure that drill cuttings can gather in the collection bag 8 and avoid them being too scattered and difficult to pour out, the opening of the collection bag 8 is connected to the flexible frame 6 by a guide channel 7, which gradually narrows from top to bottom. By setting the guide channel 7, drill cuttings can fall into the guide channel 7 after passing through the cut 2, and then slide downwards along the side wall of the guide channel 7. Because the guide channel 7 gradually narrows from top to bottom, the drill cuttings will continuously gather towards the center and then fall into the collection bag 8, allowing the drill cuttings collected in the collection bag 8 to converge together.

[0030] The specific structure of the flexible frame 6 is as follows: the flexible frame 6 is set as a rectangular frame, the flexible frame 6 includes two first side rods that are parallel to each other with the guide tube 1, two second side rods are fixedly connected between the two first side rods, and the connecting rod 9 is fixedly set on the inner side of the first side rods.

[0031] Example 2.

[0032] like Figure 5 As shown, a soft frame 6 is fixedly connected to the opening of the collection bag 8, and at least one collar 10 is fixedly connected to the soft frame 6. The guide tube 1 can pass through the collar 10 so that the soft frame 6 fits against the edge of the cut 2.

[0033] In use, the collar 10 is placed on the guide tube 1 to connect the soft frame 6 to the guide tube 1. By adjusting the position of the collar 10 on the guide tube 1, the soft frame 6 can be made to fit against the edge of the cut 2, thereby sealing the cut 2 with the soft frame 6. Then the insertion part 5 can be inserted into the hole to collect drill cuttings.

[0034] Furthermore, multiple collars 10 are provided, and the multiple collars 10 are evenly distributed along the length direction of the guide tube 1.

[0035] To ensure that drill cuttings gather in the collection bag 8 and prevent them from being too scattered and difficult to pour out, the opening of the collection bag 8 is connected to the flexible frame 6 by a guide channel 7, which gradually narrows from top to bottom. By providing the guide channel 7, drill cuttings can fall into it after passing through the cut 2, and then slide downwards along its sidewall. Because the guide channel 7 gradually narrows from top to bottom, the drill cuttings continuously converge towards the center and fall into the collection bag 8, thus ensuring that the drill cuttings collected in the collection bag 8 are gathered together.

[0036] In both Embodiment 1 and Embodiment 2 described above, the soft frame 6 can be made of conventional materials such as rubber, and the guide channel 7 can be made of metal materials such as stainless steel. Wear-resistant nylon can be bonded to the surface to improve wear resistance.

[0037] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
