[0007] Preferably, the rotating seat is cylindrical in shape, the middle part of the rotating seat is hollow, and a bottom cover is connected to the top end of the rotating seat. The bottom cover is disc-shaped and has a circular hole at the axial position. The inner opening and the side opening are both opened on the horizontal plate, and the side opening is located on one side of the inner opening.

[0008] Preferably, the limiting mechanism includes a fixed seat, a push rod slidably connected to the fixed seat, an extension frame welded to the push rod, a locking tooth welded to one end of the extension frame, an insertion rod welded to the other end of the extension frame, the insertion rod slidably connected to the limiting seat, a rack slidably connected to the limiting seat, the limiting seat welded to the cross plate of the frame, and a return spring sleeved on the insertion rod.

[0010] Preferably, the pushing mechanism includes a vertical base with a vertical groove, a rotating wheel inserted into the groove, a rocker arm rotatably connected to the rotating wheel, and a rotating rod welded to the rocker arm.

[0011] Preferably, the vertical seat and the rack are arranged in an L-shape, the vertical groove is opened along the length of the vertical seat, the rocker arm is arranged in an L-shape, and a handle is welded to the rotating rod, with the handle located outside the horizontal plate.

[0012] Preferably, the horizontal plate has an outer opening, and a rotating rod is rotatably connected inside the outer opening.

[0013] Preferably, the lifting mechanism includes a pressure plate, a vertical rod inserted into the pressure plate, an inner plate welded to the vertical rod, an upper spring sleeved on the vertical rod, a guide rod welded to the other side of the inner plate, a lifting plate slidably connected to the guide rod, a pull rope hanging on the lifting plate, a pressure plate hanging at the other end of the pull rope, and a guide wheel attached to the pull rope.

[0014] Preferably, the inner plate and the guide wheel are welded inside the vertical frame, the top of the pressure plate inside the vertical frame is triangular, and a pressure wheel is attached to the inclined side of the pressure plate. The pressure wheel is rotatably connected to the side of the rotating seat.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: This type of mud loss meter is used by first turning the outer handle. The handle drives the rotating rod to rotate inside the outer opening, and the L-shaped rocker arm swings accordingly, pushing the rotating wheel to move along the vertical groove inside the vertical seat. This, in turn, causes the vertical seat and rack to move horizontally. The rack and gear mesh and drive the connecting rod and rotating seat to rotate together, turning the bottom cover and inner cover away from the liquid cup area. At this time, the locking teeth disengage from the gears, and the limit is released. The experimenter can directly place the filter paper and gasket in the inner cover without disassembling the liquid cup. After placement, reverse the handle to drive the rotating seat to rotate back, so that the bottom cover and inner cover move below the liquid cup. Place the liquid cup in the enclosed space of the bottom cover and inner cover, then inject mud into the liquid cup, and tighten the top cap to complete the seal.

[0016] This type of mud loss meter, during the process of the rotating seat being rotated and reset by the control handle, causes the pressure roller on the side of the rotating seat to roll along the triangular inclined surface of the pressure plate, gradually pressing down on the pressure plate. The pressure plate slides downward along the vertical rod and compresses the upper spring. The pressure plate pulls the pull rope, which, after being reversed by the guide wheel, pulls the lifting plate upward along the guide rod, causing the placement frame and the upper measuring cup to rise synchronously, automatically aligning with the filtrate outlet at the center of the rotating seat shaft. This eliminates the need for manual repeated adjustments to the measuring cup height. After material loading and component alignment are completed, the retaining teeth, under the action of the reset spring, Re-engage the gears to lock the gears and rotating seat in place to prevent positional shift. Then, introduce nitrogen into the equipment for pressure testing. The mud filtrate flows into the measuring cup below through the bottom of the liquid cup and the central hole of the rotating seat shaft, completing the filtrate loss test. After the test, operate the handle again to release the limit, and rotate the bottom cover to remove the liquid cup, filter paper, and filter cake. The entire device integrates functions such as component placement, automatic alignment, and lifting and receiving of liquid, greatly simplifying disassembly and adjustment steps. The operation process is simple, effectively improving the overall efficiency of mud water loss detection. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 8As shown, the present invention provides a mud loss meter, comprising a frame 1, a liquid cup 7, a horizontal plate 2, a top plate 3, a support plate 4, a screw 5, a sealing plate 6, a baffle 8, and a measuring cup 18. The horizontal plate 2 is bolted to the upper and lower sides of the frame 1. A rotating mechanism 12 is provided on the upper horizontal plate 2, and a bottom cover 9 is connected to the rotating mechanism 12. An inner cover 10 is provided inside the bottom cover 9, and the space between the inner cover 10 and the bottom cover 9 is adapted to the liquid cup 7. A limiting mechanism 14 is connected to the rotating mechanism 12, and a pushing mechanism 15 is connected to the input end of the limiting mechanism 14. A handle is connected to the input end of the pushing mechanism 15. A vertical frame 11 is bolted to the lower horizontal plate 2, and a lifting mechanism 17 is provided inside the vertical frame 11. In practice, this device solves the problem of cumbersome experimental operation steps of traditional medium-pressure loss meters, such as disassembling the liquid cup 7, placing filter paper, assembling parts, and aligning the measuring cup 18. The complex process, long experimental time, and inconvenient operation are addressed by the frame 1, which serves as the main support for the entire machine, ensuring the stable installation of all components. The upper and lower horizontal plates 2 are used to partition and mount components such as the rotating mechanism 12 and the lifting mechanism 17. The rotating mechanism 12 drives the bottom cover 9 and the inner cover 10 to rotate and shift as a whole, enabling the liquid cup 7 to be quickly aligned and placed. The bottom cover 9 and the inner cover 10 work together to form a receiving space, which can directly place filter paper and gaskets, eliminating the need for repeated disassembly and assembly of the liquid cup 7. The limiting mechanism 14 locks the rotating mechanism 12 to prevent it from deflecting on its own during operation. The pushing mechanism 15 works with the handle to achieve manual drive, making operation simple and effortless. The lifting mechanism 17 can drive the measuring cup 18 to automatically lift and align with the filtrate outlet, eliminating the need for repeated manual height adjustments. Overall, the experimental process is simplified, greatly improving the ease of operation and experimental efficiency of mud filtrate loss detection.

[0028] The rotating mechanism 12 includes an inner opening 121, within which a rotating seat 122 is disposed. A connecting rod 125 is welded onto the rotating seat 122. A side opening 123 is provided in the direction of the connecting rod 125. A gear 124 is welded onto the connecting rod 125 within the side opening 123. The gear 124 and the connecting rod 125 are coaxially arranged. The connecting rod 125 and the rotating seat 122 are arranged in a T-shape. In practice, the inner opening 121 provides rotational space for the rotating seat 122. The T-shaped connecting rod 125 connects the rotating seat 122 and the gear 124, resulting in direct torque transmission and balanced force. The gear 124 and the connecting rod 125 rotate coaxially, which can synchronously transmit power to the rotating seat 122, precisely control the deflection angle of the rotating seat 122, and realize the switching of the positions of the bottom cover 9 and the inner cover 10.

[0029] The rotating seat 122 is cylindrical in shape and hollow in the middle. A bottom cover 9 is connected to the top end of the rotating seat 122. The bottom cover 9 is disc-shaped and has a circular hole at the axial position. The inner opening 121 and the side opening 123 are both opened on the horizontal plate 2. The side opening 123 is located on one side of the inner opening 121. In practice, the cylindrical hollow rotating seat 122 has high structural strength and smooth rotation. The circular hole at the axial position serves as a channel for the flow of filtrate. The disc-shaped bottom cover 9 and the inner cover 10 cooperate to form the position for the liquid cup 7. The positioning is regular. The inner opening 121 and the side opening 123 are arranged in sections to meet the space requirements for the rotation of the rotating seat 122 and the meshing transmission of the gear 124. The layout is compact and does not interfere with each other.

[0030] The limiting mechanism 14 includes a fixed base 142, a push rod 141 slidably connected to the fixed base 142, an extension frame 143 welded to the push rod 141, a locking tooth 147 welded to one end of the extension frame 143, and an insertion rod 144 welded to the other end of the extension frame 143. The insertion rod 144 is slidably connected to a limiting seat 146, the limiting seat 146 is welded to the cross plate 2 of the frame 1, a rack 148 slidably connected to the limiting seat 146, and a return spring 145 sleeved on the insertion rod 144. In the process, the fixed seat 142 provides sliding support for the push rod 141. The push rod 141 moves synchronously with the extension frame 143 and the locking tooth 147. The locking tooth 147 can be locked into the tooth groove of the gear 124 to achieve locking and positioning. The insertion rod 144 slides in a direction within the limiting seat 146 to ensure that the movement trajectory of the component does not deviate. The return spring 145 provides rebound force, which can drive the component to automatically reset after the external force is released. The rack 148 serves as a power transmission component and meshes with the gear 124 to achieve power transmission.

[0031] The push rod 141 and the extension frame 143 are arranged in an L-shape. The locking teeth 147 on the extension frame 143 face the gear 124 inside the side opening 123 and are engaged with the gear 124. The return spring 145 is located between the extension frame 143 and the limiting seat 146. The limiting seat 146 is arranged in an L-shape. The rack 148 on the limiting seat 146 meshes with the gear 124 inside the side opening 123. In practice, the L-shaped structure is suitable for the installation space, the transmission angle is reasonable, and the operation is labor-saving. The locking teeth 147 and the gear 124 are tightly engaged, effectively locking the position of the gear 124 and the rotating seat 122 to prevent rotation and shaking during operation. The return spring 145 is reasonably positioned, with stable deformation and reliable rebound. The limiting seat 146 slides and guides the rack 148 to ensure the meshing accuracy of the rack 148 and the gear 124, and the transmission is smooth without skipping teeth.

[0032] The pushing mechanism 15 includes a vertical base 151, on which a vertical groove 152 is provided. A rotating wheel 153 is inserted into the vertical groove 152. A rocker arm 154 is rotatably connected to the rotating wheel 153. A rotating rod 155 is welded to the rocker arm 154. In practice, the vertical groove 152 provides a moving track for the rotating wheel 153, converting the swinging motion of the rocker arm 154 into the horizontal displacement of the vertical base 151. The rocker arm 154 and the rotating rod 155 are linked to convert the rotation of the handle into linear thrust, realizing the power steering transmission. The structure is simple and the transmission response is sensitive.

[0033] The vertical seat 151 and the rack 148 are arranged in an L-shape. The vertical groove 152 is opened along the length of the vertical seat 151. The rocker arm 154 is arranged in an L-shape. A handle is welded on the rotating rod 155. The handle is located outside the horizontal plate 2. In practice, the L-shaped vertical seat 151 and the rack 148 are rigidly connected and can move horizontally synchronously. The longitudinal vertical groove 152 ensures that the rotating wheel 153 has sufficient stroke. The external handle makes it easy for the experimenter to operate it by hand without the need for auxiliary tools, which is in line with the on-site operating habits.

[0034] The horizontal plate 2 has an outer opening 13, and a rotating rod 155 is rotatably connected inside the outer opening 13. In practice, the outer opening 13 provides a rotation fulcrum and movement space for the rotating rod 155, limits the rotation range of the rotating rod 155, ensures smooth swing of the handle, and at the same time plays a protective role for the rotating rod 155 to prevent jamming.

[0035] The lifting mechanism 17 includes a pressure plate 171, a vertical rod 175 inserted into the pressure plate 171, an inner plate 178 welded onto the vertical rod 175, an upper spring 176 sleeved on the vertical rod 175, a guide rod 177 welded to the other side of the inner plate 178, a lifting plate 174 slidably connected to the guide rod 177, a pull rope 173 hanging on the lifting plate 174, the other end of the pull rope 173 hanging on the pressure plate 171, and a guide wheel 172 attached to the pull rope 173. In operation, the vertical rod 175 vertically guides the pressure plate 171, the upper spring 176 normally pushes the pressure plate 171 back to its original position, the guide rod 177 limits the sliding trajectory of the lifting plate 174 to prevent deviation, and the guide wheel 172 changes the direction of force on the pull rope 173. When the pressure plate 171 moves down, the pull rope 173 pulls the lifting plate 174 up and down, thereby driving the measuring cup 18 to complete the height adjustment. The linkage action is stable and reliable.

[0036] The inner plate 178 and the guide wheel 172 are welded inside the vertical frame 11. The top of the pressure plate 171 inside the vertical frame 11 is triangular. The pressure wheel 16 is attached to the inclined side of the pressure plate 171. The pressure wheel 16 is rotatably connected to the side of the rotating seat 122. In practice, the inner plate 178 and the guide wheel 172 are fixed inside the vertical frame 11 to ensure that the reference of the lifting mechanism 17 remains unchanged. The triangular inclined pressure plate 171 and the pressure wheel 16 are in rolling contact. When the rotating seat 122 rotates, it can smoothly press down the pressure plate 171. The frictional resistance is small and the action is naturally connected, realizing the linkage between the rotation action and the lifting action.

[0037] The working principle of this invention is as follows: After installing the horizontal plate 2, top plate 3, and support plate 4 on the frame 1, the lower horizontal plate 2 can fix the vertical frame 11, and the upper horizontal plate 2 can have an inner opening 121. The rotating seat 122 inside the inner opening 121 can rotate within the inner opening 121 via the connecting rod 125. The bottom cover 9 and inner cover 10 on the rotating seat 122 can rotate, thereby rotating towards or away from the liquid cup 7. The horizontal plate 2 also has... The connecting rod 125 inside the side opening 123 can be connected to the gear 124. The gear 124 meshes with the rack 148, and the rack 148 can move horizontally at the position of the limit seat 146. The vertical seat 151 is welded to the rack 148. The vertical groove 152 on the vertical seat 151 is inserted into the rotating wheel 153 on the rocker arm 154. The rocker arm 154 is installed in the outer opening 13 of the horizontal plate 2 through the rotating rod 155. The handle is connected to the rotating rod 155. The handle can drive the rotating rod 155 to rotate within the outer opening 13. The rotating rod 155 drives the rotating wheel 153 to move within the vertical groove 152 of the vertical seat 151 via the rocker arm 154, thereby pushing the vertical seat 151 to move horizontally when rotating. The rack 148 on the vertical seat 151 can drive the gear 124 to rotate. When the gear 124 rotates, it can drive the rotating seat 122 to rotate via the connecting rod 125. The bottom cover 9 on the rotating seat 122 will move to the position of the liquid cup 7. During testing, the bottom cover 9 is moved away from the liquid cup 7 by operating the handle. Then, the filter paper and gasket are placed inside the inner cover 10. Then, the bottom cover 9 is moved to the position of the liquid cup 7 by controlling the handle. At this time, the liquid cup 7 blocks the bottom cover 9. After manually pushing the liquid cup 7 upward, the liquid cup 7 will fall into the space between the bottom cover 9 and the inner cover 10. Then, mud is injected, and then the screw 5 is turned to make the cap press the liquid cup 7 tightly. Before turning the handle, place the measuring cup 18 into the placement rack 179. When the handle is turned, the rotating seat 122 will drive the pressure roller 16 to press down the pressure plate 171 during rotation. The pressure plate 171 will move down along the vertical rod 175. When the pressure plate 171 moves down, it will pull the lifting plate 174 through the pull rope 173. The lifting plate 174 will drive the placement rack 179 to move up, thereby moving the measuring cup 18 to the output port position of the rotating seat 122. After nitrogen is injected, liquid will flow into the measuring cup 18. The whole detection process is convenient and quick, reduces assembly steps, and improves detection efficiency.
