Description

Technical Field

[0001] The utility model relates to the technical field of petroleum fracturing proppant detection, in particular to a wrist-type oscillograph for detecting the turbidity of petroleum fracturing proppants. Background Technique

[0002] The function of the fracturing proppant is to fill the artificial fractures generated by fracturing. After the formation pressure is released, it supports the fractures to form an oil and gas seepage channel with high conductivity. Commonly used proppants include natural quartz sand and artificial ceramsite. Turbidity inspection is an important evaluation index in the experiment of fracturing proppants. When conducting turbidity inspection, applying the shaking force and shaking speed that meet the national standard requirements to the test sample has a great impact on the test results. Currently, there are roughly two methods: one is manual operation, and the other is using an oscillator. Using an oscillator can set corresponding parameters, greatly improving the impact of manual operation, and more effectively and simply controlling the shaking force and shaking speed.

[0003] Existing wrist-type oscillographs are basically all manually adjusted and controlled, without the function of digital transmission, and it is difficult to match modern networked and digital management. Whether the data is complete, accurate, and timely is directly related to the success or failure of digital management.

[0004] For example, the wrist-type oscillograph disclosed in Chinese Patent CN203648454U meets the requirements of the inspection standard for relevant parameters, realizes the digitization and standardization of the sample oscillation process, greatly reducing the labor intensity and the influence of human factors on the test results. At the same time, it can also be operated through the touch screen to simply and effectively adjust the working rotation speed and rotation angle, and output data such as rotation speed, rotation angle, and working time to the upper computer for further sorting, summarizing, and printing. When working, information such as the oscillation time and the rotation speed of the motor can be set through the touch screen; the processor controls the servo motor through the servo driver, and the servo motor drives the rotation shaft to rotate, and then oscillates the sample bottle through the gripper.

[0005] However, this wrist-type oscillograph can only clamp two sample bottles through the clamping claws at both ends, so only two sample bottles can be oscillated at a time, affecting the oscillation efficiency of the reagent.

[0006] Therefore, we urgently need to provide a wrist-type oscillograph for detecting the turbidity of petroleum fracturing proppants that can oscillate multiple sample bottles at one time. Content of the Utility Model

[0007] The purpose of the utility model is to provide a wrist-type oscillograph for detecting the turbidity of petroleum fracturing proppants, so as to solve the problem that the wrist-type oscillograph can only clamp two sample bottles through the clamping claws at both ends, so only two sample bottles can be oscillated at a time, affecting the oscillation efficiency of the reagent as mentioned in the above background technique.

[0008] To achieve the above object, the present utility model provides the following technical solution: A wrist-type oscillating instrument for detecting the turbidity of petroleum fracturing proppants, comprising an oscillating instrument main body and a swinging rod. The swinging rod is installed above the left and right ends of the oscillating instrument main body. An oscillating mechanism is connected to the outer ends of the oscillating instrument main body and the swinging rod. The oscillating mechanism includes an oscillating unit and a fixing unit. The oscillating unit is arranged at the outer end of the swinging rod, and the fixing unit is arranged at the lower outer side of the oscillating instrument main body.

[0009] The oscillating unit includes a sliding rod, a fixing frame, a circular shaft, a rotating rod, a clamping plate, a threaded rod, a rotating handle, and a fixing bolt. The sliding rod is connected to the inside of the swinging rod. The fixing frame is fixedly connected to one end of the sliding rod. The circular shaft is fixedly connected to the left and right ends inside the fixing frame. The rotating rod is connected to the outer end of the circular shaft. The clamping plate is fixedly connected to the other end of the rotating rod away from the circular shaft. The threaded rod is connected to the front of the left and right ends inside the fixing frame. The rotating handle is fixedly connected to the end of the threaded rod away from the fixing frame. The fixing bolt is connected to the upper inside of the swinging rod.

[0010] Further improvement lies in that a rotating hole is provided at the middle position of the inner end of the rotating rod away from the clamping plate, and the outer side of the circular shaft is rotatably connected to the inner side of the rotating hole. Thus, the rotating rod can rotate around the circular shaft.

[0011] Further improvement lies in that first threaded holes are provided at the left and right ends in front of the inside of the fixing frame, and the end of the threaded rod away from the rotating handle abuts against the outer side of the rotating rod. Thus, after placing the upper end of the reagent bottle between the clamping plates, then rotating the rotating rod around the circular shaft, when the clamping plates move to the outer side of the upper end of the reagent bottle, and then rotating the rotating handle to drive the threaded rod to rotate and move to contact the outer side of the rotating rod at the same time, the rotating rod can be fixed, and at the same time, the clamping plates are fixed to the outer side of the upper end of the reagent bottle, and the reagent bottle is clamped and fixed.

[0012] Further improvement lies in that a sliding hole is provided in the swinging rod, a second threaded hole is provided at the position above the sliding hole inside the swinging rod, the outer side of the sliding rod is slidably connected to the inner side of the sliding hole, the outer side of the fixing bolt is threadedly connected to the inner side of the second threaded hole, and the lower end of the fixing bolt abuts against the upper outer side of the sliding rod. Thus, sliding the sliding rod along the inner side of the sliding hole, driving the reagent bottle clamped between the clamping plates to move to a suitable position, and then threadedly connecting the fixing bolt to the inner side of the second threaded hole until the lower side of the fixing bolt contacts the upper outer side of the sliding rod, the sliding rod can be fixed in the sliding hole, so that the distance between the reagent bottle and the swinging rod can be adjusted, and thus the oscillation amplitude of the reagent bottle can be adjusted.

[0013] Further improvement lies in that the fixing unit includes a connecting plate and a suction cup. The connecting plate is fixedly connected to the front and rear ends below the left and right sides of the shaker main body, and the suction cup is fixedly connected to one end of the lower side of the connecting plate away from the shaker main body.

[0014] Further improvement lies in that the lower end of the suction cup adsorbs to the desktop. Thus, when the shaker main body is placed on the desktop and at the same time the suction cup adsorbs to the upper side of the desktop, the shaker main body can be firmly fixed to the desktop.

[0015] Further improvement lies in that a rubber pad is fixedly connected to the outer side of the clamping plate. Thus, when the reagent bottle is clamped by the clamping plate, the rubber pad on the outer side of the clamping plate contacts the outer side of the upper end of the reagent bottle, and the reagent bottle can be clamped more firmly.

[0016] In summary, the present application discloses a wrist-type shaker for detecting the turbidity of petroleum fracturing proppants.

[0017] Through the oscillation unit arranged at the outer end of the swing rod, multiple reagent bottles can be clamped at one time in this technical solution. Thus, after the shaker main body is turned on, multiple reagent bottles can be oscillated, and the oscillation efficiency of the reagent is accelerated.

[0018] Furthermore, when the shaker main body is placed on the desktop and at the same time the suction cup adsorbs to the upper side of the desktop, the shaker main body can be firmly fixed to the desktop. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0026] Embodiment 1:

[0027] An oil fracturing proppant turbidity detection wrist-type shaker, which includes a shaker main body 1 and a swing rod 2. The swing rod 2 is installed above the left and right ends of the shaker main body 1. An oscillation mechanism is connected to the outer ends of the shaker main body 1 and the swing rod 2. The oscillation mechanism includes an oscillation unit and a fixing unit. The oscillation unit is arranged at the outer end of the swing rod 2, and the fixing unit is arranged at the lower outer side of the shaker main body 1.

[0028] The oscillation unit includes a sliding rod 301, a fixed frame 302, a round shaft 303, a rotating rod 304, a clamping plate 305, a threaded rod 306, a rotating handle 307 and a fixing bolt 308. The sliding rod 301 is connected to the inside of the swing rod 2. The fixed frame 302 is fixedly connected to one end of the sliding rod 301. The round shaft 303 is fixedly connected to the left and right ends inside the fixed frame 302. The rotating rod 304 is connected to the outer end of the round shaft 303. The clamping plate 305 is fixedly connected to the other end of the rotating rod 304 away from the round shaft 303. A rotating hole is opened in the middle position at the end of the rotating rod 304 away from the clamping plate 305. The outer side of the round shaft 303 is rotatably connected to the inner side of the rotating hole. Thus, the rotating rod 304 can rotate around the round shaft 303.

[0029] The threaded rod 306 is connected to the front of the left and right ends inside the fixed frame 302. The rotating handle 307 is fixedly connected to the end of the threaded rod 306 away from the fixed frame 302. The fixing bolt 308 is connected to the upper inside of the swing rod 2. First threaded holes are opened at the left and right ends in the front of the fixed frame 302. The end of the threaded rod 306 away from the rotating handle 307 abuts against the outer side of the rotating rod 304. Thus, after placing the upper end of the reagent bottle between the clamping plates 305, then rotating the rotating rod 304 around the round shaft 303 so that the clamping plate 305 moves to the outer side of the upper end of the reagent bottle, and then rotating the rotating handle 307 to drive the threaded rod 306 to rotate and move to contact the outer side of the rotating rod 304 at the same time, the rotating rod 304 can be fixed, and at the same time, the clamping plate 305 is fixed to the outer side of the upper end of the reagent bottle, and the reagent bottle is clamped and fixed.

[0030] The inside of the swing rod 2 is provided with a sliding hole, and a second threaded hole is provided at a position above the sliding hole inside the swing rod 2. The outside of the sliding rod 301 is slidably connected to the inside of the sliding hole, the outside of the fixing bolt 308 is threadedly connected to the inside of the second threaded hole, and the lower end of the fixing bolt 308 abuts against the upper end of the outside of the sliding rod 301. Thus, slide the sliding rod 301 along the inside of the sliding hole. After driving the reagent bottle clamped between the clamping plates 305 to move to a suitable position, then thread the fixing bolt 308 into the inside of the second threaded hole. Until the lower side of the fixing bolt 308 contacts the upper end of the outside of the sliding rod 301, the sliding rod 301 can be fixed in the sliding hole, so that the distance between the reagent bottle and the swing rod 2 can be adjusted, and thus the oscillation amplitude of the reagent bottle can be adjusted.

[0031] Embodiment 2:

[0032] Based on Embodiment 1: The fixing unit includes a connecting plate 401 and a suction cup 402. The connecting plate 401 is fixedly connected to the front and rear ends of the lower sides of the left and right sides of the shaker main body 1, and the suction cup 402 is fixedly connected to one end of the lower side of the connecting plate 401 away from the shaker main body 1.

[0033] The lower end of the suction cup 402 is adsorbed on the desktop. Thus, when the shaker main body 1 is placed on the desktop and the suction cup 402 is adsorbed on the upper side of the desktop at the same time, the shaker main body 1 can be firmly fixed on the desktop.

[0034] Embodiment 3:

[0035] Based on Embodiment 1: A rubber pad is fixedly connected to the outside of the clamping plate 305. Thus, when the reagent bottle is clamped by the clamping plate 305, the rubber pad on the outside of the clamping plate 305 contacts the upper outer side of the reagent bottle, and the reagent bottle can be clamped more firmly.

[0036] Working principle: When in use, first place the upper end of the reagent bottle between the clamping plates 305, and then rotate the rotating rod 304 around the round shaft 303 until the clamping plates 305 move to the outer side of the upper end of the reagent bottle. Then rotate the rotary handle 307 to drive the threaded rod 306 to rotate and move to contact the outside of the rotating rod 304 at the same time, clamp and fix the reagent bottle. Then slide the sliding rod 301 along the inside of the sliding hole until the reagent bottle moves to a suitable position. Then rotate the fixing bolt 308 to make it move downward along the inside of the second threaded hole until it contacts the upper end of the outside of the sliding rod 301, fix the sliding rod 301, and then start the shaker main body 1 to make the swing rod 2 swing to oscillate the reagent bottle.
