DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings:

[0039] The purpose of the present invention is to provide a drill bit cleaning device for petroleum engineering to solve the technical problem that the drill bit cleaning device in the prior art cleans the drill bit by relative movement of the drill bit or the brush, which cannot achieve thorough cleaning and consumes more water, resulting in waste.

[0040] Example 1

[0041] See also Figure 1-7 The present invention provides a drill bit cleaning device for petroleum engineering, comprising a cleaning box 1, wherein the cleaning box 1 is divided into a cleaning chamber 2 and a collecting chamber 3 by a partition, and a drill bit 4 is rotatably connected in the cleaning chamber 2; a driving component, comprising a driving member and a rotating member, wherein the rotating member is rotatably connected in the cleaning chamber 2, the rotating member is located above the drill bit 4 and is connected to the drill bit 4 through a clamp, the driving member is arranged at the top of the cleaning box 1, the driving member has two output ends with opposite movement directions and reciprocating motion, the rotating member is located between the two output ends, and the output end drives the rotating member to reciprocate; a brush component is fixed on the two output ends of the driving member and contacts with the surface of the drill bit 4; a spray component is arranged outside the cleaning box 1 and is connected with the clamp; a filter component is arranged in the collecting chamber 3, and the filtered water outlet of the filter is connected with the cleaning chamber 2 through the water collecting member.

[0042] When cleaning the drill bit 4, the drill bit 4 is placed in the cleaning chamber 2, and the rotating part and the drill bit 4 are connected by a clamp, and water is poured into the cleaning box 1. The water surface in the cleaning box 1 submerges the drill bit 4, and then the driving part is started. The two output ends of the driving part reciprocate and move in opposite directions, driving the two brush parts to move toward each other on both sides of the drill bit 4. At the same time, the movement of the output end drives the rotating part to rotate back and forth, so that the drill bit 4 rotates back and forth, ensuring that the brush parts scrape and clean different positions of the drill bit and in different directions. In this process, the cleaned gravel enters the collection chamber 3 under the action of gravity. At the same time, due to the existence of the barrier, the collection chamber 3 is less disturbed. The gravel falls under the action of gravity and is filtered by the filter. The clean water outlet of the filter is connected to the water collection part, and the filtered water is collected for subsequent cleaning.

[0043] After the initial cleaning of the drill bit is completed, the water in the cleaning box 1 is drained, and then the spray part is turned on. The spray part sprays water to the drill bit 4 and assists the brush part in cleaning. At the same time, during the spraying process, the impurities on the drill bit 4, the brush part, and the inner wall of the cleaning chamber 2 are washed into the collection chamber 3. While cleaning the drill bit 4, the cleaning structure in the cleaning chamber 2 can also be cleaned to ensure the effect of the next batch of cleaning.

[0044] Specifically, a door 36 is hinged on the side wall of the cleaning box 1, the door 36 is connected to the cleaning chamber 2, and the connection between the door 36 and the cleaning box 1 is sealed. A side entry mode is set, and the drill bit 4 is put into the cleaning box 1 or taken out from the side wall of the cleaning box 1.

[0045] Specifically, according to Figure 5 and Figure 6 As shown, the rotating assembly includes a rotating plate 5 arranged in the cleaning chamber 2, a rotating shaft 6 is fixedly connected to the top of the rotating plate 5, and the rotating shaft 6 is rotatably connected to the inner wall of the top of the cleaning box 1. The clamping part includes a connecting column 7 connected to the rotating plate 5, a connecting plate 8 is fixedly connected to the bottom end of the connecting column 7, and a clamping column 9 that cooperates with the end of the drill bit 4 is fixedly connected to the bottom end of the connecting plate 8. The clamping column 9 is connected to the end of the drill bit 4 and drives the drill bit 4 to rotate.

[0046] In this embodiment, the rotating shaft 6 is used to support the rotating plate 5 so that it can rotate relative to the cleaning box 1. At the same time, the connecting column 7 is connected to the rotating plate 5. When the rotating plate 5 rotates, the connecting column 7 is driven to rotate, thereby driving the connecting plate 8 to rotate, and the clamping column 9 is used to connect with the drill bit 4.

[0047] Among them, the end of the clamping column 9 that contacts the drill bit 4 has multiple grooves, which correspond to the ends of the drill bit 4 and allow the ends of the drill bit 4 to extend into the grooves to achieve the clamping connection between the clamping column 9 and the drill bit 4, thereby enabling the clamping column 9 to drive the drill bit 4 to rotate.

[0048] The end shape of the clamping column 9 can be replaced according to the end shape of the drill bit 4 to achieve the clamping effect on the drill bit 4, or other fixing structures can be used to fix the drill bit 4 on the connecting plate 8.

[0049] Among them, the connecting column 7 is a polygonal column structure, and the other end of the connecting column 7 passes through the rotating plate 5 and the rotating shaft 6 and extends out of the cleaning box 1. The connecting column 7 is slidably connected to the rotating plate 5, and the rotating plate 5 drives the connecting column 7 to rotate.

[0050] Since the connecting column 7 is a polygonal structure, when the rotating plate 5 rotates, the connecting column 7 can rotate with the rotating plate 5. At the same time, the connecting column 7 can slide up and down relative to the rotating plate 5. Under this setting, the different lengths of the drill bit 4 are taken into consideration. When the length of the drill bit 4 changes or the drill bit 4 is inserted or removed, the connecting column 7 can be pulled up or down to achieve the connection of drill bits 4 of different lengths and the insertion and removal of the drill bit 4.

[0051] Specifically, a circular hole is provided at the top of the cleaning box 1 for the connection column 7 to move, and the circular hole does not hinder the rotation and up and down movement of the connection column 7; wherein the connection column 7 is one of a triangle, a quadrilateral, a pentagon, a hexagon, etc.

[0052] according to Figure 1 , Figure 2 and Figure 6As shown, the spray assembly includes a clean water tank 10 arranged outside the cleaning box 1, and interconnected cavities are opened inside the connecting column 7 and the connecting plate 8. The clean water tank 10 is connected to the end of the connecting column 7 located outside the cleaning box 1 through a clean water pipe 11. A plurality of nozzles 12 are axially fixed to the bottom end of the connecting plate 8. The nozzles 12 are arranged corresponding to the drill bits 4, and the nozzles 12 are connected to the cavities in the connecting plate 8.

[0053] A clean water tank 10 is arranged outside the cleaning tank 1, and the clean water tank 10 is used to spray the drill bit 4 when the drill bit 4 is cleaned again. The clean water in the clean water tank 10 enters the connecting column 7 through the clean water pipe 11 under the action of the driving device, enters the connecting plate 8 from the connecting column 7 and is sprayed to the drill bit 4 by multiple nozzles 12 to flush the drill bit 4. During the flushing process, the drill bit 4 reciprocates under the action of the rotating plate 5.

[0054] Specifically, the clean water pipe 11 is a hose. Since the rotating plate 5 drives the connecting column 7 to rotate back and forth, the clean water pipe 11 can twist back and forth without being too much entangled on the connecting column 7. At the same time, in order to increase the service life of the clean water pipe 11, when the drill bit 4 is cleaned for the first time, the clean water pipe 11 may not be connected to the connecting column 7.

[0055] In order to further improve the service life of the water purification pipe 11, the drill bit 4 does not rotate when flushing the drill bit 4. After flushing, the water purification pipe 11 is removed and the drill bit 4 is rotated and reciprocated for multiple times to complete the flushing of the drill bit 4 again.

[0056] Specifically, according to Figure 3 and Figure 4 As shown, a bracket 13 is fixedly connected to the top of the cleaning box 1, and a driving member includes a driving motor 14 fixed to the top of the bracket 13. A connecting plate 15 is fixedly connected to the output end of the driving motor 14, and a connecting rod 16 is fixedly connected to the bottom end of the connecting plate 15. Two inner walls opposite to each other at the top of the cleaning chamber 2 are respectively fixedly connected to slide rails 17. The two output ends of the driving member are sliders 18 respectively slidably connected to the two slide rails 17. A long groove 19 corresponding to the slider 18 is opened at the top of the cleaning box 1. A connecting block 20 is fixedly connected to the top of a slider 18. The other end of the connecting block 20 is penetrated by the long groove 19 and extends out of the cleaning box 1. A pushing plate 21 is fixedly connected to the connecting block 20. A through groove 22 is opened at the top of the pushing plate 21. The connecting rod 16 is located in the through groove 22 and pushes the pushing plate 21 to move.

[0057] A rack 23 is fixedly connected to the side wall of the slider 18 , and gear teeth 24 are fixed to the outer wall of the rotating plate 5 , and the gear teeth 24 mesh with the rack 23 .

[0058] In this embodiment, the driving motor 14 on the bracket 13 works, driving the connecting plate 15 and the connecting rod 16 on the connecting plate 15 to rotate, and the slider 18 is limited in the slide rail 17. At the same time, a connecting block 20 on the top of the slider 18 extends out of the cleaning box 1 through the long groove 19. A through groove 22 is provided on the push plate 21 on the connecting block 20. The connecting rod 16 is penetrated in the through groove 22 and is slidably connected with the push plate 21. By rotating the driving motor 14, the connecting rod 16 drives the push plate 21 to reciprocate, and at the same time, the rack 23 is engaged with the gear teeth 24 on the rotating plate 5. The rack 23 drives the rotating plate 5 to reciprocate and rotate. At the same time, the rotating plate 5 drives the other rack 23 to move, so that the two racks 23 move back and forth toward each other.

[0059] The connecting column 7 is located below the pushing plate 21 , and the existence of the connecting column 7 does not affect the normal horizontal movement of the pushing plate 21 .

[0060] In this embodiment, the brush assembly is a brush plate 25 fixed to the bottom end of the rack 23 , and the brush end of the brush plate 25 is in contact with the drill bit 4 .

[0061] The length of the brush end on the brush plate 25 is different, and the brush end matches the drill bit 4. Under this setting, the brush plate 25 matches the drill bit 4, can be better in contact with the drill bit 4 and clean it, and when the model of the drill bit 4 changes, the brush plate 25 can be replaced.

[0062] In another embodiment of the present invention, referring to Figure 7 The brush plate 25 is fixed with a plurality of spring groups 37 from top to bottom, and the other end of the spring group 37 is fixed with a base plate 38, and bristles are installed on the end surface of the plate body close to the drill bit 4. Under this arrangement, under the action of different spring groups 37, the bristles on the base plate 38 are in contact with the surface of the drill bit 4, and there is no need or less need to replace the brush parts according to the type of the drill bit 4.

[0063] Specifically, according to Figure 5 As shown, the partition is a partition plate 26 fixed to the inner wall of the cleaning box 1, and a plurality of water inlets 27 are provided at the top of the partition plate 26. The cleaning chamber 2 is connected with the collecting chamber 3 through the water inlets 27. The filter element includes a filter screen 28 fixed obliquely to the collecting chamber 3. A sand discharge pipe 29 is provided at the lower end of the filter screen 28, and the water inlet end of the sand discharge pipe 29 is located above the filter screen 28.

[0064] The partition plate 26 is a plate structure and has a plurality of water inlets 27 on its surface. In the cleaning chamber 2, due to the movement of the brush plate 25 and the drill bit 4, the disturbance in the cleaning chamber 2 is large, and the sand and gravel after cleaning falls into the collecting chamber 3 under the action of gravity. Under the action of the partition plate 26, the collecting chamber 3 is better disturbed, so the sand and gravel can settle quickly and be separated from water by the filter screen 28. The separated sand and gravel can be extracted from the cleaning box 1 through the sand discharge pipe 29.

[0065] according to Figure 1 and Figure 2 As shown, the water collecting device includes a water collecting box 30 arranged outside the cleaning box 1, the water collecting box 30 is connected to the collecting chamber 3 through a water collecting pipe 31, and the water inlet end of the water collecting pipe 31 is located below the filter 28, and the water outlet end of the water collecting box 30 is connected to the cleaning chamber 2 through a water inlet pipe 32.

[0066] The water collecting tank 30 is used to collect filtered water and sprayed water. When the drill bit 4 is cleaned for the first time, the water collecting pipe 31 is closed, and the water stored in the water collecting tank 30 is injected into the cleaning box 1 to perform the initial cleaning on the drill bit 4. After the initial cleaning is completed, the water collecting pipe 31 is opened to collect the filtered water. When the water in the cleaning chamber 2 is drained, the clean water pipe 11 is opened to spray and clean the drill bit 4 again, and the water collecting tank 30 collects the cleaning water.

[0067] In addition, the water in the water collecting tank 30 should be replaced regularly to ensure the cleaning effect on the drill bit 4.

[0068] Reference Figure 3 , Figure 6 The top end of the partition plate 26 is fixedly connected to a limiting rod 33 , and the end of the limiting rod 33 extends into the drill bit 4 to limit the drill bit 4 .

[0069] The limiting rod 33 is inserted into the drill rod end of the drill bit 4 to limit the drill bit 4 . The limiting rod 33 cooperates with the clamping column 9 to set the drill bit 4 to a limited position.

[0070] Reference Figure 1 , Figure 2 The cleaning chamber 2 is connected with an oil drain pipe 34, the oil inlet end of the oil drain pipe 34 corresponds to the liquid surface in the cleaning chamber 2, and the oil outlet end of the oil drain pipe 34 is connected with an oil collecting tank 35. When the drill bit 4 is cleaned, the oil adhering to the drill bit 4 is cleaned and floats on the liquid surface, so the oil drain pipe 34 is provided to extract the cleaned oil, that is, after the initial cleaning is completed, the drill bit 4 is left in the cleaning tank 1 for a period of time, and then the oil drain pipe 34 is opened to first extract the oil layer on the liquid surface, and then the remaining cleaning water is discharged.

[0071] Example 2

[0072] Reference Figure 8 The difference from Example 1 is that the limit rod 33 is rotatably connected to the partition plate 26, the other end face of the limit rod 33 is fixedly connected to a stirring rod 39, the end of the stirring rod 39 extends into the collecting chamber 3, the side wall of the stirring rod 39 is fixedly connected to a friction plate 40, the bottom end of the partition plate is fixedly connected to a connecting cover 41, the bottom end of the connecting cover 41 is connected and fixed with a cylindrical filter screen 42, the cylindrical filter screen 42 is sleeved on the outside of the stirring rod 39, and the end of the friction plate 40 away from the stirring rod 39 is in contact with the inner wall of the cylindrical filter screen 42, the sand discharge pipe 29 is connected to the inside of the cylindrical filter screen 42, and the water collecting pipe 31 is connected to the outside of the cylindrical filter screen 42.

[0073] Under this structural setting, used water enters the cylindrical filter 42 under the action of the connecting cover 41 and is filtered by the cylindrical filter 42. Since the stirring rod 39 rotates with the drill bit 4, the friction plate 40 is used to scrape the inner wall of the cylindrical filter 42 to prevent sand and gravel from clogging the cylindrical filter 42.

[0074] Example 3

[0075] Reference Fig. 9 On the basis of Example 1 or Example 2, a backflow prevention cover 43 is fixed on the water outlet 27, the diameter of the backflow prevention cover 43 away from the water outlet 27 is smaller than the diameter of the backflow prevention cover 43 near the water outlet 27, and a plurality of openings 44 are opened in the circumferential direction of the side wall of the backflow prevention cover 43.

[0076] With this structural setting, used water enters the collecting chamber 3 through the opening 44. At the same time, due to the existence of the reflux cover 43, the disturbance of the cleaning chamber 2 to the collecting chamber 3 is further reduced, thereby preventing the backflow of sand and impurities.

[0077] In summary, the present invention provides a drill bit cleaning device for petroleum engineering, wherein a driving assembly is arranged on a cleaning box, a cleaning chamber and a collecting chamber are arranged in the cleaning box, and the drill bit is assembled in the cleaning chamber. The driving assembly includes a driving member and a rotating member. The driving member is provided with two output ends with opposite movement directions and reciprocating motion on the cleaning box. The driving end of the rotating member is respectively connected to the two output ends of the driving member. Under the action of the driving member, the brush member arranged on the output end can be driven to reciprocate, thereby changing the relative position of the brush member and the drill bit. At the same time, the driving member can drive the rotating member to rotate, and the drill bit is driven to reciprocate through the rotating member, so the relative position of the brush member and the drill bit is constantly changed, thereby expanding the contact range between the drill bit and the brush member and improving the cleaning effect. A spray assembly, a brush assembly and a filter assembly are arranged in the cleaning box, which effectively improve the cleaning of the drill bit and the filtering and collection in the box. The input end of the water collecting device arranged outside the cleaning box is connected with the collecting chamber, and the output end is connected with the cleaning chamber, thereby greatly reducing water consumption.

[0078] A filter is arranged in the cleaning box, and water used for cleaning the drill bit enters the collecting chamber and is filtered by the filter. The filtered clean water can be used again in subsequent cleaning operations. After the initial cleaning of the drill bit is completed, the drill bit is flushed by the spray part and cleaned again by the brush part. The water flow for cleaning the drill bit again can flush the cleaning box and finally be filtered and collected, which improves the cleaning effect of the drill bit on the one hand and reduces water consumption on the other.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
