[0027] The following will be combined with the attached Figures 1 to 5 The utility model is described in detail, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides an efficient petroleum water content detection device through improvement. Figure 1 - Figure 2As shown, the calibration device 1 includes a driving box 101, the upper end of the driving box 101 is fixedly connected to two storage barrels 102, the two storage barrels 102 are filled with water and oil respectively, and the lower end of the storage barrel 102 is fixedly connected to a constant temperature barrel 103 for constant temperature control of water and oil. The structure and principle of the constant temperature barrel 103 are both prior art and will not be repeated here. The left and right side walls of the driving box 101 are both installed with injection components 2 for quantitatively discharging water or oil;

[0029] The injection assembly 2 includes a metering cylinder 201 connected to the drive box 101, a piston 202 is slidably connected inside the metering cylinder 201, a side wall of the piston 202 close to the calibration device 1 is rotatably connected to a screw rod 203, a moving disk 204 is slidably connected inside the metering cylinder 201, a plurality of limit bars are fixedly connected to the inner wall of the metering cylinder 201, and a plurality of sliding grooves matching the limit bars are cut on the moving disk 204. The moving disk 204 is slidably connected through the limit bars to prevent the moving disk 204 from rotating when the screw rod 203 rotates, and the moving disk 204 Threadedly connected to the screw rod 203, a plurality of fixed rods 205 are fixedly connected between the movable disk 204 and the piston 202, a suction pipe 206 is connected between the end of the metering cylinder 201 away from the driving box 101 and the storage barrel 102, a discharge pipe 207 is connected between the end of the metering cylinder 201 away from the driving box 101 and the constant temperature barrel 103, a sample reflux component 4 for detecting sample reflux is arranged between the suction pipe 206 and the discharge pipe 207 and the metering cylinder 201, and a driving control quantity component 3 for discharging the detection sample is arranged inside the driving box 101.

[0030] In this embodiment: when the screw rod 203 rotates, the movable disk 204 is driven to move through the threaded action, and the movable disk 204 drives the piston 202 to move through multiple fixed rods 205. When the piston 202 moves toward the screw rod 203, the water or oil inside the storage barrel 102 is sucked through the suction pipe 206. When the piston 202 moves in the opposite direction of the screw rod 203, the water and oil inside the metering cylinder 201 are discharged to the interior of the constant temperature barrel 103 through the discharge pipe 207, so that the water and oil are kept at a constant temperature in the constant temperature barrel 103, and the one-way flow of liquid in the suction pipe 206, the metering cylinder 201 and the discharge pipe 207 is realized through the one-way valve 404 inside the sample reflux assembly 4.

[0031] In the above embodiment, in order to control the number of rotations of the screw rod 203, thereby controlling the moving distance of the piston 202, and thus realizing the control of the discharge flow of water or oil, and in order to realize the flow control of the two injection assemblies 2 by a single stepping motor 308, the following method can be adopted:

[0032] In a preferred embodiment, Figure 3 - Figure 4As shown, the driving control component 3 includes a connecting rod 301 rotatably connected to the opposite end of the two screw rods 203, two symmetrically arranged conical blocks 302 are slidably connected to the connecting rod 301, a fixed tube 303 is fixedly connected between the two conical blocks 302, and a first gear 304 is fixedly connected to the fixed tube 303. A same moving box 305 is slidably connected between the inner walls of the front and rear sides of the metering cylinder 201, and the fixed tube 303 is rotatably connected to the moving box 305. A second gear 306 meshing with the first gear 304 is rotatably connected inside the moving box 305, and a stepping motor 3 is installed on the side wall of the metering cylinder 201. 08. The structure and principle of the stepper motor 308 are all prior art and will not be described in detail here. The output end of the stepper motor 308 is fixedly connected with a square telescopic rod 307, and the square telescopic rod 307 passes through the moving box 305 and is fixedly connected with the second gear 306. Bearings are installed at the penetration points of the square telescopic rod 307, the moving box 305 and the metering cylinder 201. The opposite ends of the two lead screws 203 are fixedly connected with an electromagnet 309 that is magnetically attracted to the conical block 302 close to it. The structure and principle of the electromagnet 309 are all prior art and will not be described in detail here. A transmission sleeve 310 is fixedly connected to the electromagnet 309.

[0033] It is worth noting that a layer of rubber pad is fixedly connected to the inner wall of the transmission sleeve 310 and the outer wall of the conical block 302, and a plurality of anti-slip grooves are cut on the rubber pad. When the conical block 302 contacts the inner wall of the transmission sleeve 310, a stable transmission effect can be achieved by relying on friction. In addition, a plurality of clips are fixedly connected to the connecting rod 301, and the two conical blocks 302 are slidingly connected to the connecting rod 301 through the clips. When the conical block 302 rotates, it can also drive the connecting rod 301 to rotate, so that the connecting rod 301 can provide a stable axial support force for the conical block 302.

[0034] In this embodiment, when it is necessary to discharge the oil in one of the storage barrels 102, the electromagnet 309 at the corresponding screw rod 203 is started, so that the electromagnet 309 attracts the conical block 302 close to it, and then drives the conical block 302 to move until the conical block 302 contacts the inner wall of the transmission sleeve 310. At this time, the staff starts the stepper motor 308, and the stepper motor 308 drives the second gear 306 to rotate through the square telescopic rod 307. The second gear 306 drives the first gear 304 to rotate, so that the piston 202 can extract a preset flow of oil. Then the stepper motor 308 is reversed again, so that the oil in the metering cylinder 201 is discharged to the constant temperature barrel 103 through the discharge pipe 207 for constant temperature. When it is necessary to discharge the water in another storage barrel 102, it is necessary to start the electromagnet 309 at the corresponding screw rod 203 and repeat the above steps again.

[0035] It is worth noting that before the staff starts the stepper motor 308, the staff needs to set a flow value on the computer. The computer calculates the moving distance of the piston 202 through the inner diameter of the metering cylinder 201, and then calculates the number of rotations of the screw 203, and controls the stepper motor 308 through the controller to achieve the effect of precise control of the flow. Among them, the computer and the controller are not shown in the figure. The computer and the controller are both existing technologies, and their structural principles will not be repeated. At the same time, the device also includes a power supply, a switch, a controller, a power supply cable and other devices because they are not the main technology and will not be described in detail; in addition, when the conical block 302 moves, the square telescopic rod 307 will be extended and retracted, but it will not affect the stepper motor 308 driving the second gear 306 to rotate through the square telescopic rod 307.

[0036] refer to Figure 5 The sample reflux component 4 includes a valve housing 401 connected to the metering cylinder 201, a valve core 402 is rotatably connected inside the valve housing 401, two valve holes 403 are drilled on the valve core 402, the suction pipe 206 and the discharge pipe 207 are respectively connected to the metering cylinder 201 through the two valve holes 403, a one-way valve 404 is installed inside the valve hole 403, a micro motor 405 is fixedly connected to the upper end of the valve housing 401, and the output end of the micro motor 405 is fixedly connected to the valve core 402, a flow sensor 5 is installed on the suction pipe 206, the structure and principle of the flow sensor 5 are all existing technologies, which will not be repeated here, and the flow sensor 5 is electrically connected to the stepper motor 308 and the micro motor 405.

[0037] In this embodiment, when the water or oil in the storage barrel 102 is used up during the process of the metering cylinder 201 extracting water or oil, it will be detected by the flow sensor 5 and a signal will be sent to the computer. The computer drives the controller, and the controller will control the micro motor 405 to rotate 180 degrees to reverse the conduction direction of the two one-way valves 404. At the same time, the controller will also control the stepper motor 308 to reverse to the initial state, and the stepper motor 308 will drive the piston 202 to move in the opposite direction, and the water or oil extracted from the metering cylinder 201 will be discharged back to the storage barrel 102 through the one-way valve 404, and the staff will fill it up, which effectively avoids the staff not knowing the water or oil content in the metering cylinder 201, resulting in the test sample ratio in the constant temperature barrel 103 not meeting the expected effect.
