DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment. It should be noted that 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 making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 14 The present invention provides a technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a driving mechanism 2, which is used to drive the pump body; A separation mechanism 3, the separation mechanism 3 is used for separation and transportation of liquid; The driving mechanism 2 is connected to the separating mechanism 3 , and a supporting platform 1 is fixedly mounted on the bottom of both the driving mechanism 2 and the separating mechanism 3 .

[0037] The driving mechanism 2 includes a frame 21, which is arranged on the top of the support platform 1. A servo motor 22 is fixedly connected to the top of the frame 21, and a shaft sleeve disk 23 is fixedly connected to the outer side of the output end of the servo motor 22. A spline block 25 is inserted into the side of the shaft sleeve disk 23 away from the servo motor 22, wherein the spline block 25 is inserted into the other side of the shaft sleeve disk 23 and is fixedly connected to a protective component 24.

[0038] The end of the spline block 25 away from the shaft sleeve disk 23 is fixedly connected with a single-end shaft 26, and the end of the single-end shaft 26 close to the spline block 25 is fixedly connected with a return spring 27. The end of the return spring 27 away from the single-end shaft 26 is squeezed and adapted with the shaft sleeve disk 23. A slot 28 is provided at the end of the single-end shaft 26 away from the return spring 27. A connecting shaft 29 is adapted for sliding inside the slot 28. A support shaft seat 203 is fixedly connected to the end of the connecting shaft 29 away from the slot 28. The bottom of the support shaft seat 203 is fixedly connected to the support platform 1. An outer groove 20 is provided on the outer side of the connecting shaft 29. A slider 201 is adapted for sliding inside the outer groove 20. By starting the servo motor 22, the shaft sleeve disk 23 connected to the outer side of its output end will rotate forward, wherein the interior of the shaft sleeve disk 23 is sleeved with the spline block 25. In addition, the spring 2 Under the compression force of 46, the external disk 245 connected to the other end will move with the insertion rod 242 toward the direction of the spline block 25, wherein the other end of the insertion rod 242 is connected to the compensation rod 243, and finally the compensation rod 243 will be inserted into the interior of the spline block 25 to realize the fastening connection between the spline block 25 and the sleeve disk 23, so that the rotational force of the sleeve disk 23 will be transmitted to the spline block 25, and the other end of the spline block 25 is connected to the single-port shaft 26, and the other end of the single-port shaft 26 is connected to the slider 201 through the double-headed rod 202, and the slider 201 is slidably adapted on the outer groove 20 opened on the surface of the connecting shaft 29, wherein the sliding of the slider 201 on the outer groove 20 is at a vertical angle to the rotation of the motor, so they do not affect each other. The side of the slider 201 away from the support shaft seat 203 is fixedly connected with the double-headed rod 202, and the end of the double-headed rod 202 away from the slider 201 is fixedly connected to the single-port shaft 26. The compensation rod 243 extends outward from the inside of the spline block 25, and then under the tensile force of the return spring 27, the single-end shaft 26 connected to the other end of the spline block 25 will move in the direction away from the shaft sleeve 23, and the slot 28 opened on the other end of the single-end shaft 26 will be engaged with the connecting shaft 29, and at the same time, the double-headed rod 202 connected to the other end of the single-end shaft 26 will move outward along the outer groove 20 with the slider 201, thereby separating the servo motor 22 from the pump body in the separation mechanism 3, preventing the servo motor 22 from continuing to transmit vibration to the separation mechanism 3, causing damage to the pump body and the shaft. At the same time, it also prevents the pump body from continuing to transmit vibration to the servo motor 22, causing wear and cracking of the output shaft of the servo motor 22.

[0039] like Figure 6 , Figure 7 and Figure 8 As shown, the protective component 24 includes a Y-shaped frame 241, which is fixedly connected to the outer side of the shaft sleeve disk 23. An insertion rod 242 is inserted on the surface of the Y-shaped frame 241, and one end of the insertion rod 242 is fixedly connected to a compensation rod 243, and the end of the compensation rod 243 away from the insertion rod 242 is inserted into the interior of the spline block 25, and an expansion body 244 is arranged inside the spline block 25, wherein the expansion body 244 is squeezed and adapted with the compensation rod 243, and the end of the insertion rod 242 away from the compensation rod 243 is fixedly connected to an external disk 245, and a spring 246 is fixedly connected to the side of the external disk 245 close to the insertion rod 242, and the end of the spring 246 away from the external disk 245 is fixedly connected to the Y-shaped frame 241, and a No. 1 sleeve strip 240 is provided on the outer side of the external disk 245, and a No. 1 rack 249 is fixedly connected to the end of the No. 1 sleeve strip 240 away from the external disk 245. In addition, when the servo motor 22 or the pump body in the separation mechanism 3 is stuck or vibrates excessively during operation, the expansion body 244 arranged inside the spline block 25 will be broken due to the vibration and the impact of the compensation rod 243. In addition, the jamming phenomenon will also cause the servo motor 22 to vibrate violently. The expansion body 244 is a plastic hollow ball filled with an air bag. Therefore, when the expansion body 244 is broken, the air bag will instantly swell and squeeze the compensation rod 243 outward, and then the compensation rod 243 will stretch the spring 246 with the insertion rod 242, causing the compensation rod 243 to extend from the inside of the spline block 25, thereby preparing for the subsequent separation of the spline block 25 and the shaft sleeve disk 23.

[0040] The end of the Y-shaped frame 241 away from the shaft sleeve disk 23 is fixedly connected to a Z-shaped cover 247, and the central part inside the Z-shaped cover 247 is rotatably connected to a gear 248 via a rotating shaft. The outer side of the gear 248 is meshed with a No. 1 rack 249 for transmission, and the side of the gear 248 away from the No. 1 rack 249 is meshed with a No. 2 rack 2401 for transmission, wherein the No. 1 rack 249 and the No. 2 rack 2401 are both slidably adapted inside the Z-shaped cover 247, and the outer side of the No. 2 rack 2401 is fixedly connected to a No. 2 rack 2402. The outer side of the external disk 245 is connected to the No. 1 rack 249 through the No. 1 sleeve 240. Therefore, when the expansion body 244 ruptures, the No. 1 rack 249 will move outward together with the external disk 245 and the inserted rod 242. The No. 1 rack 249 is meshed with the gear 248 for transmission, and the other side of the gear 248 is meshed with the No. 2 rack 2401 for transmission. Therefore, the No. 2 rack 2401 will move outward with the No. 2 sleeve 2402 connected thereto. In addition, the No. 2 sleeve 2402 is connected to the external disk 245 on the other end of the spline block 25. Therefore, when one of the two expansion bodies 244 in the spline block 25 ruptures, the external disks 245 on both ends will move outward synchronously together, and the two compensation rods 243 will extend outward from the spline block 25 together.

[0041] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the separation mechanism 3 includes a compensator 31, one end of the compensator 31 is fixedly connected to the support shaft seat 203, the end of the compensator 31 close to the support shaft seat 203 is rotatably connected to the connecting shaft 29, the end of the compensator 31 away from the support shaft seat 203 is fixedly connected to the pump casing 32, a gasket 33 is arranged inside the pump casing 32, wherein the central parts of the pump casing 32 and the gasket 33 are rotatably connected to the pump shaft 34, the inner end surface of the pump shaft 34 is connected to the connecting shaft 29, the end of the pump shaft 34 away from the connecting shaft 29 is fixedly connected to the impeller 35, the impeller 35 is rotatably connected to the inside of the pump casing 32, an inspection component 38 is fixedly installed on the top of the pump casing 32, a blade 39 is fixedly connected to the side of the impeller 35 away from the gasket 33, the end of the pump casing 32 away from the compensator 31 is fixedly connected to the external shell 36, and the end of the external shell 36 away from the pump casing 32 is fixedly connected to the suction pipe 37. As the connecting shaft 29 rotates forward, the pump shaft 34 connected to the other end thereof will rotate forward, and drive the impeller 35 fixedly connected to the outer side thereof to rotate together. Before starting the centrifugal pump, the pump housing 32 and the suction pipe 37 need to be filled with the liquid to be transported to prevent the occurrence of air binding. When the pump shaft 34 drives the impeller 35 to rotate at high speed, the blades 39 on the impeller 35 will drive the liquid to rotate together, so that the liquid obtains centrifugal force. Under the action of centrifugal force, the liquid is thrown from the center of the impeller 35 to the edge of the impeller 35, and a low-pressure area is formed at the center of the impeller 35. There is a pressure difference between the suction liquid surface and the center of the impeller 35. Under the action of this pressure difference, the liquid will be continuously sucked from the suction container through the suction pipe 37 to the center of the impeller 35. After the liquid enters the impeller 35, as the impeller 35 rotates, the liquid is accelerated in the flow channel between the blades 39. The impeller 35 does work on the liquid, increasing the kinetic energy and static pressure energy of the liquid, thereby achieving liquid pressurization. The pressurized liquid is collected at the pump outlet in the pump housing 32, and then transported to the desired place through the extrusion pipe 381. When the liquid is discharged from the pump, a low-pressure area will be formed at the center of the impeller 35, and new liquid will be sucked into the center of the impeller 35 under the action of the pressure difference. This cycle repeats, and the centrifugal pump can continuously transport liquid.

[0042] The inspection assembly 38 includes an extrusion pipe 381, which is fixedly connected to the top of the pump housing 32. An outer connecting plate 382 is fixedly connected to the outer side of the extrusion pipe 381, a telescopic rod 383 is fixedly connected to the top of the outer connecting plate 382, ​​a docking flange 384 is fixedly connected to the top of the telescopic rod 383, and a sleeve pipe 385 is fixedly connected to the center of the bottom of the docking flange 384. The liquid discharged from the extrusion pipe 381 will be discharged outward along the sleeve pipe 385 and the docking flange 384 in sequence, wherein the docking flange 384 can be lifted upward, so that the telescopic rod 383 connected to the bottom thereof will extend upward, and the center of the bottom of the docking flange 384 is connected to the sleeve pipe 385, so the sleeve pipe 385 will move upward accordingly, and the extrusion pipe 381 originally covered by the sleeve pipe 385 is exposed, wherein the extrusion pipe 381 is transparent, so that the operator can directly observe the flow state, liquid level height, etc. of the material in the pipeline or container through the glass sight glass.

[0043] The surface of the extrusion tube 381 is provided with a No. 1 perforation 3804, and the extrusion tube 381 is slidably adapted inside the sleeve tube 385. The surface of the sleeve tube 385 is respectively provided with a No. 2 perforation 3805 and a vertical groove 386. The interior of the vertical groove 386 is fixedly connected with a No. 1 trapezoidal block 387. The top of the No. 1 trapezoidal block 387 is extruded and adapted with a No. 2 trapezoidal block 388. The No. 2 trapezoidal block 388 is slidably adapted inside the vertical groove 386. The outer side of the telescopic rod 383 is fixedly connected with a rod ring 380. The rod ring The outer side of 380 is fixedly connected with a cross bar 3801, and the end of the cross bar 3801 away from the rod ring 380 is sleeved with a plug-in block 389, and the end of the plug-in block 389 away from the cross bar 3801 is fixedly connected to the second trapezoidal block 388, and the end of the plug-in block 389 away from the second trapezoidal block 388 is fixedly connected with the second magnetic block 3803, and the end of the second magnetic block 3803 away from the plug-in block 389 is provided with a first magnetic block 3802, and the first magnetic block 3802 is fixedly connected to the inside of the cross bar 3801. A vertical groove 386 is provided on the outer side of the sleeve 385, and the interior of the vertical groove 386 is fixedly connected with a No. 1 trapezoidal block 387 and slidably connected with a No. 2 trapezoidal block 388. If the sleeve 385 continues to move upward, the No. 1 trapezoidal block 387 will squeeze and block the No. 2 trapezoidal block 388, and the operator will be reminded that the end of the first stage of operation has been reached. If the operator still lifts the sleeve 385 upward, the No. 2 trapezoidal block 388 squeezed by the No. 1 trapezoidal block 387 will be inserted into the interior of the cross bar 3801 with the plug-in block 389, and the No. 2 magnetic block 3803 fixedly connected to the other end of the plug-in block 389 will approach the No. 1 magnetic block 3802, and the repulsive force is maintained between the two magnetic blocks to reset the plug-in block 389 and the No. 2 trapezoidal block 388. Then the No. 1 trapezoidal block 387 will pass over the No. 2 trapezoidal block 388 and continue to move upward along the vertical groove 386 until the No. 1 perforation 3804 respectively provided on the extrusion tube 381 coincides with the No. 2 perforation 3805 provided on the sleeve tube 385. At this time, the liquid will spray outward, thereby enabling the inspector to detect the outflowing water flow and determine whether the water flow fluctuation has changed too much.

[0044] When the present invention is used: first, the servo motor 22 is started, so that the sleeve disc 23 connected to the outer side of the output end thereof will rotate in the positive direction, wherein the interior of the sleeve disc 23 is sleeved with the spline block 25, and under the compression force of the spring 246, the external disc 245 connected to the other end thereof will move toward the direction of the spline block 25 with the insertion rod 242, wherein the other end of the insertion rod 242 is connected to the compensation rod 243, and finally the compensation rod 243 will be inserted into the interior of the spline block 25 , to achieve a fastening connection between the spline block 25 and the sleeve disk 23, so that the rotational force of the sleeve disk 23 will be transmitted to the spline block 25, and the other end of the spline block 25 is connected to the single-end shaft 26, and the other end of the single-end shaft 26 is connected to the slider 201 through a double-headed rod 202, and the slider 201 is slidably adapted on the outer groove 20 opened on the surface of the connecting shaft 29, wherein the sliding of the slider 201 on the outer groove 20 is at a vertical angle to the rotation of the motor, and therefore do not affect each other.

[0045] As the connecting shaft 29 rotates forward, the pump shaft 34 connected to the other end thereof will rotate forward, and drive the impeller 35 fixedly connected to the outer side thereof to rotate together. Before starting the centrifugal pump, the pump housing 32 and the suction pipe 37 need to be filled with the liquid to be transported to prevent the occurrence of air binding. When the pump shaft 34 drives the impeller 35 to rotate at high speed, the blades 39 on the impeller 35 will drive the liquid to rotate together, so that the liquid obtains centrifugal force. Under the action of centrifugal force, the liquid is thrown from the center of the impeller 35 to the edge of the impeller 35, and a low-pressure area is formed at the center of the impeller 35. There is a pressure difference between the suction liquid surface and the center of the impeller 35. Under the action of this pressure difference, the liquid will be continuously sucked from the suction container through the suction pipe 37 to the center of the impeller 35. After the liquid enters the impeller 35, as the impeller 35 rotates, the liquid is accelerated in the flow channel between the blades 39. The impeller 35 does work on the liquid, increasing the kinetic energy and static pressure energy of the liquid, thereby achieving liquid pressurization. The pressurized liquid is collected at the pump outlet in the pump housing 32, and then transported to the desired place through the extrusion pipe 381. When the liquid is discharged from the pump, a low-pressure area will be formed at the center of the impeller 35, and new liquid will be sucked into the center of the impeller 35 under the action of the pressure difference. This cycle repeats, and the centrifugal pump can continuously transport liquid.
