[0001] The invention relates to the technical field of drilling fluid lubricant production, and in particular to a drilling fluid lubricant storage device. Background Art

[0002] The core function of drilling fluid lubricants is to reduce the flow resistance and filter cake friction coefficient of drilling fluid, reduce drill bit torque and increase water horsepower, and effectively prevent sticking problems. Its main ingredients include animal and plant oil derivatives, synthetic compounds (such as fatty phenolamines) and surfactants. These lubricants are mostly liquid and have excellent lubrication properties.

The two are doubly sealed. When one of the two is deformed or damaged, the other will seal the main body and the cover body, and the groove and the sealing block are of special-shaped design to reduce the possibility of air leakage, thereby achieving the purpose of increasing the overall sealing effect; a servo motor is provided, and the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade and the connecting rod to rotate. The rotation of the stirring blade can achieve the effect of stirring the lubricant to prevent precipitation.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. Example 1

The storage structure 100 is provided with a stirring mechanism 300 for stirring the lubricant and a pressure stabilizing mechanism 400 for keeping the internal air pressure of the storage structure 100 in a balanced state; Among them, the supporting mechanism 200 includes a supporting part 210, on which a telescopic part 220 for adjusting the local structural position of the supporting part 210 is provided, and a guide part 230 for limiting is provided at each of the four corners of the supporting part 210, and a leg part 240 for adjusting the supporting flatness of the supporting part 210 is provided at the bottom of the guide part 230, and two groups of moving parts 250 for convenient movement and a driving part 260 for realizing the retraction and extension operation of the moving parts 250 are provided at the bottom of the supporting part 210, and each group of moving parts 250 is symmetrically arranged with two. Example 2

[0023] like Figure 1-Figure 8 As shown, the drilling fluid lubricant storage device provided in this embodiment is different from that in embodiment 1 in that: The storage structure 100 includes an oil storage tank 110, the top of the oil storage tank 110 is connected to an oil inlet pipe 120, and the lower part of the surface of the oil storage tank 110 is connected to an oil outlet pipe 130. By connecting the oil inlet pipe 120 and the oil outlet pipe 130 to external equipment respectively, the drilling fluid lubricant can be discharged into the oil storage tank 110 through the oil inlet pipe 120, or the drilling fluid lubricant in the oil storage tank 110 can be discharged through the oil outlet pipe 130. The top of the oil storage tank 110 and the lower part of the surface are also connected to a maintenance pipe 140 respectively. The maintenance port of the maintenance pipe 140 is installed with a sealing cover 150 through bolts and nuts. An escalator 160 is installed on the surface of the oil storage tank 110. Through the coordinated use of the maintenance pipe 140, the sealing cover 150 and the escalator 160, it is convenient for the staff to perform regular inspection and maintenance on the interior of the oil storage tank 110 to ensure the normal operation of the storage structure 100.

[0024] The supporting portion 210 includes a support plate 211 located at the bottom of the oil storage tank 110, and a hollow rod 212 is movably connected at the four corners of the support plate 211. A cavity 213 with a cross structure is opened inside the support plate 211. Two telescopic portions 220 are arranged in the upper and lower inner cavities of the cavity 213, and the two cavities 213 are arranged perpendicular to each other. One of the telescopic portions 220 is used to adjust the distance between two relatively arranged hollow rods 212, and the other telescopic portion 220 is used to adjust the distance between the other two relatively arranged hollow rods 212. A guide portion 230 is respectively provided between two adjacent hollow rods 212. The four hollow rods 212 and the guide portion 230 together form a rectangular structure. By placing the supporting portion 210 on the ground and then hoisting the storage structure 100 onto the supporting portion 210, it is possible to avoid the bottom of the storage structure 100 from directly contacting the ground, so as to prevent corrosion damage to the bottom of the storage tank.

[0025] The telescopic part 220 includes a first double-headed cylinder 221 installed in the inner cavity of the cavity 213, and the two output ends of the first double-headed cylinder 221 are fixedly connected with the first connecting rod 222. The end of the first connecting rod 222 away from the first double-headed cylinder 221 can be movably penetrated to the outside of the support plate 211 and fixedly connected with the corresponding hollow rod 212. By starting the first double-headed cylinder 221, the first connecting rod 222 and the corresponding hollow rod 212 can be driven to move synchronously along the axial direction of the first double-headed cylinder 221 through the output end of the first double-headed cylinder 221, and then the distance between the two relatively arranged hollow rods 212 can be adjusted, so that the distance between the hollow rod 212 and the support plate 211 can be adjusted according to the diameter of the oil storage tank 110, so as to expand the application range of the supporting part 210.

[0026] The guide portion 230 includes an upper support block 231 located between two adjacent hollow rods 212, and a guide rod 232 is fixedly connected to both sides of the upper support block 231. The end of the guide rod 232 away from the upper support block 231 movably penetrates into the inner cavity of the corresponding hollow rod 212, and the surface of the guide rod 232 is slidably connected to the inner wall surface of the corresponding hollow rod 212. The leg portion 240 is arranged at the bottom of the upper support block 231. The guide portion 230 can not only limit the hollow rod 212, so that when the spacing between the two relatively arranged hollow rods 212 is adjusted, the guide portion 230 can be driven to move synchronously, so that the guide rod 232 can slide in the inner cavity of the adjacent hollow rod 212 to ensure the stability of the end of the hollow rod 212 when it moves, but also provide an installation basis for the leg portion 240.

[0027] The leg portion 240 includes a single-head cylinder 241 installed at the bottom of the upper support block 231, and the output end of the single-head cylinder 241 is provided with a support 242 in contact with the ground; Among them, the support 242 includes a lower support block 2421, a spherical groove 2422 is opened on the top of the lower support block 2421, and a convex ball 2423 is movably embedded in the inner cavity of the spherical groove 2422. The convex ball 2423 is fixedly connected to the output end of the single-head cylinder 241. By starting the setting of the support leg part 240, the supporting part 210 can be lifted, and water can be drained through the gap between the supporting part 210 and the ground to prevent water from accumulating on the outside of the supporting part 210; at the same time, when the ground is uneven, the single-head cylinder 241 can be started to adjust the flatness of the supporting part 210 to ensure that the installation of the storage structure 100 meets the required requirements.

[0028] The moving part 250 includes a bracket 251 arranged at the bottom of the support plate 211, and a roller 252 is installed at the bottom end of the bracket 251. Through the setting of the moving part 250, the single-head cylinder 241 is started to make the support 242 away from the ground. By using the support of the moving part 250, the support mechanism 200 is connected to the traction equipment, so that the support mechanism 200 can be easily moved to the desired position.

[0029] The driving part 260 includes a second double-headed cylinder 261 installed at the bottom of the support plate 211. The two output ends of the second double-headed cylinder 261 are fixedly connected to a C-shaped frame 262. Each C-shaped frame 262 is arranged in a one-to-one correspondence with each group of brackets 251. The two ends of the C-shaped frame 262 are respectively connected to the bracket 251 through a linkage, and the top of the bracket 251 is rotatably connected to the bottom of the support plate 211 through a rotating shaft. By starting the second double-headed cylinder 261, the two C-shaped frames 262 can be driven to move toward or away from each other. The C-shaped frame 262 can drive the corresponding bracket 251 to rotate around the rotating shaft at the bottom of the support plate 211 through the linkage, so as to realize the retracting and releasing operation of the moving part 250. When not in use, the moving part 250 is folded and stored at the bottom of the support plate 211. When in use, the moving part 250 is flipped open and supported for movement.

[0030] The linkage member includes a side plate 263 fixedly connected to the end of the U-shaped frame 262, a protrusion 264 is fixedly connected to the side plate 263, and a second connecting rod 265 is rotatably connected between the protrusion 264 and the adjacent bracket 251 through a rotating shaft. When the U-shaped frame 262 drives the side plate 263 and the protrusion 264 to move synchronously, the second connecting rod 265 can be used to pull or push the bracket 251 to rotate around the rotating shaft at the bottom of the support plate 211, so that the bevel angle of the bracket 251 changes; a limiting groove 266 is provided on the top of the side plate 263, and two adjacent limiting grooves are A limit strip 267 parallel to the axial direction of the second double-headed cylinder 261 is slidably connected between 266, and the top of the limit strip 267 is fixedly connected to the bottom of the support plate 211. Through the coordinated use of the limit groove 266 and the limit strip 267, the side plate 263 can be guided, so that the side plate 263 can stably move horizontally along the axial direction of the second double-headed cylinder 261. The cross-section of the limit groove 266 and the limit strip 267 is a dovetail or inverted T-shaped structure, which can provide auxiliary support for the linkage part and further improve the stability of the linkage part during operation.

[0031] In this embodiment, the telescopic part 220 is added with a distance adjustment equation. In this embodiment, the telescopic part 220 adjusts the distance between the two relatively arranged hollow rods 212 through the first double-headed cylinder 221. In order to more accurately control the moving distance of the hollow rod 212, the following equation can be introduced: Assume that the target spacing of the hollow rod 212 to be adjusted is D, the initial spacing is D0, the stroke of the first double-headed cylinder 221 is L, the length of the first connecting rod 222 is j, and the angle between the first double-headed cylinder 221 and the hollow rod 212 is θ.

[0032] According to the trigonometric function relationship, the relationship between the adjusted spacing D and each parameter is: D = D0 + 2Lsinθ; Meanwhile, considering the length j of the first connecting rod 222, in practical applications, the stroke L of the first double-headed cylinder 221 needs to satisfy: ; Example: Assuming that the diameter of the oil storage tank 110 is 2 m, the initial spacing D0 of the hollow rods 212 of the supporting part 210 is 1 m, the length j of the first connecting rod 222 is 0.8 m, and the angle θ between the first double-headed cylinder 221 and the hollow rod 212 is 30°, the stroke L required by the first double-headed cylinder 221 can be calculated by the above equation: D = 2m; ; Verify again whether L meets the travel restriction condition: ; Since L=1m is greater than 0.62m, it means that the length or angle of the first connecting rod 222 currently set is not appropriate and needs to be adjusted to ensure that the spacing of the hollow rods 212 can be accurately adjusted.

[0033] Technical effect: By introducing the above equation, the required stroke of the first double-headed cylinder 221 can be accurately calculated according to the size of the oil storage tank 110 before installation, thereby improving the adaptation accuracy of the supporting part 210 to oil storage tanks 110 of different sizes and ensuring the stability of the installation of the storage structure 100.

[0034] Working principle: When the storage structure 100 needs to be installed, first, the support mechanism 200 is hung on the traction device, and the traction device and the roller 252 can be used to move the support mechanism 200 to the desired position; secondly, the second double-headed cylinder 261 is started, so that the output end of the second double-headed cylinder 261 drives the two U-shaped frames 262 to move relative to each other, and the U-shaped frame 262 drives the side plate 263, the protrusion 264 and the limit groove 266 to move synchronously, so that the side plate 263 slides on the surface of the limit strip 267, and the protrusion 264 and the limit groove 266 are moved synchronously. The block 264 drives one end of the second connecting rod 265 to move synchronously, and the other end of the second connecting rod 265 drives the bracket 251 to rotate with the rotating shaft at the bottom of the support plate 211 as the axis until the bracket 251 is in a horizontal state, so that the folding and retracting operation of the moving part 250 can be realized. At this time, the supporting part 210 can be supported by the leg part 240; from then on, according to the diameter size of the oil storage tank 110, the two first double-headed cylinders 221 are started in sequence, so that the output end of the first double-headed cylinder 221 drives the corresponding two first connecting rods The hollow rod 212 moves in opposite directions, and the hollow rod 212 drives the guide rod 232 in its inner cavity and the upper support block 231 at the end to move synchronously, so that the other guide rod 232 on the upper support block 231 slides in the inner cavity of the corresponding hollow rod 212, and the upper support block 231 also drives the support leg 240 to move synchronously until the hollow rod 212 is moved to the desired position; then, when the installation ground is uneven, the single-head cylinder 241 at the corresponding position can be started separately, so that the output end of the single-head cylinder 241 drives the support 242 Gradually move away from or approach the upper support block 231. At the same time, the lower support block 2421 can rotate on the surface of the convex ball 2423, so that the bottom of the lower support block 2421 is stably attached to the ground, and the leveling operation of the supporting part 210 can be achieved; finally, the storage structure 100 can be placed on the top of the supporting part 210 by using the lifting equipment, so that the bottom of the oil storage tank 110 is in contact with the bottom of the support plate 211 and the hollow rod 212, and the support mechanism 200 can be used to support and lift the storage structure 100. Example 3

[0035] like Figure 1-Figure 3 As shown, the drilling fluid lubricant storage device provided in this embodiment is different from that in embodiment 2 in that: The stirring mechanism 300 includes a motor 310 installed at the center of the top of the oil storage tank 110, the output shaft of the motor 310 is fixedly connected to a rotating rod 320, the bottom end of the rotating rod 320 is movably penetrated into the inner cavity of the oil storage tank 110, the surface of the rotating rod 320 is rotatably connected to the penetration of the oil storage tank 110 through a sealed bearing, and the surface of the rotating rod 320 is fixedly connected to a plurality of stirring blades 330 at equal intervals from top to bottom, and the plurality of stirring blades 330 are fixedly connected together with a scraper 34 in contact with the inner wall surface of the oil storage tank 110. 0, the top of the oil storage tank 110 is fixedly connected with a protective shell 350, and the motor 310 is installed in the inner cavity of the protective shell 350. By starting the motor 310, the rotating rod 320, the stirring blade 330 and the scraper 340 can be driven to rotate synchronously through the output shaft of the motor 310, so as to stir the drilling fluid lubricant in the oil storage tank 110 to prevent precipitation. At the same time, the inner wall surface of the oil storage tank 110 can be scraped and swept, which is convenient for the subsequent cleaning operation of the inner cavity of the oil storage tank 110. Example 4

[0036] like Figure 1 , Figure 2 , Figure 3 as well as Fig. 9 As shown, the drilling fluid lubricant storage device provided in this embodiment is different from that in embodiment 3 in that: The pressure stabilizing mechanism 400 includes a vent pipe 410 connected to the top of the oil storage tank 110, a valve 420 is installed on the vent pipe 410, and an air pressure sensor is installed in the inner cavity of the oil storage tank 110. The real-time air pressure in the oil storage tank 110 is detected by the air pressure sensor. When the real-time air pressure value in the oil storage tank 110 exceeds or falls below the limit air pressure range value, the valve 420 is controlled to open, and the oil storage tank 110 is connected to the outside air through the vent pipe 410, so that the air pressure in the oil storage tank 110 is consistent with the outside air pressure, so as to avoid feeding or discharging of the oil storage tank 110. When the oil tank 110 is heated, or when the temperature in the oil storage tank 110 changes, the air pressure in the oil storage tank 110 changes, causing the appearance of the oil storage tank 110 to deform. A circular ring 430 is fixedly connected to the upper part of the surface of the vent pipe 410. The surface of the circular ring 430 is annular and equidistantly fixed with a number of diagonal braces 440. A rain cap 450 is fixedly connected between the diagonal braces 440. The rain cap 450 is located above the vent pipe 410. The rain cap 450 can shield and protect the top of the vent pipe 410, effectively preventing rainwater or fallen leaves from accumulating in the vent pipe 410.

However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
