Description

Technical Field

[0001] The present invention relates to the technical field of mud pumps, and particularly to a protective housing for an F-type mud pump used in petroleum and petrochemical industries. Background Art

[0002] In the field of oil drilling, a mud pump is a machine that transports mud or flushing fluids such as water into a borehole. The F-type mud pump is a common type of mud pump and is widely used in drilling operations in the petroleum and petrochemical industries to cool the drill bit, remove rock cuttings, and transport them to the surface.

[0003] During the operation of the mud pump, it will come into contact with a large amount of mud and other impurities. The mud pump delivery motor, as the main power output component of the mud pump, if the mud pump output motor is affected by impurities such as mud, it will cause damage to the function of the mud pump output motor, and further cause damage to the overall device's usage function, seriously affecting the device's mud processing efficiency. When the device is used outdoors and encounters rain or snow weather, water directly enters the interior of the mud pump output motor, which will also affect the usage function of the mud pump output motor. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a protective housing for an F-type mud pump used in petroleum and petrochemical industries, including a mud pump body. A mud pump output motor is provided on the mud pump body. A protective cover is provided outside the mud pump output motor. A protective groove is opened on the protective cover. One side of the protective cover close to the mud pump body is connected to the mud pump body. The mud pump output motor is located inside the protective groove, and an auxiliary mechanism is provided inside the protective groove.

[0005] Preferably, the auxiliary mechanism includes a movable plate and a rotating block. Two movable plates are movably installed at the top end of the inner wall of the protective groove. One side of the movable plate away from the top end of the inner wall of the protective groove is movably connected to a connecting member, and a rotating block is movably installed inside the connecting member.

[0006] Preferably, a vibration sensor is installed on one side of the rotating block, a temperature sensor is installed on the other side of the rotating block, a rotating motor is installed on the side wall of the connecting member, and the output end of the rotating motor movably penetrates the side wall of the connecting member and is connected to the rotating block.

[0007] Preferably, an annular sliding groove is opened at the top end of the inner wall of the protective groove, and an annular electric slider is installed on one side of the movable plate close to the annular sliding groove. The annular electric slider is slidably installed inside the annular sliding groove.

[0008] Preferably, a moving sliding groove is opened on one side of the movable plate away from the top end of the inner wall of the protective groove, and a moving electric slider is slidably installed inside the moving sliding groove. One side of the moving electric slider close to the connecting member is connected to the connecting member.

[0009] Preferably, an electric telescopic rod is installed on one side of the movable electric slider close to the connecting member. The telescopic end of the electric telescopic rod faces the connecting member, and the telescopic end of the electric telescopic rod is connected to the connecting member.

[0010] Preferably, a sliding block is movably installed at one end of the rotating block away from the connecting member. An abutting roller is rotatably installed at one end of the sliding block away from the connecting member. A detection mechanism is provided at one end of the sliding block close to the rotating block.

[0011] Preferably, a sliding groove is formed at one end of the rotating block away from the connecting member. One end of the sliding block close to the sliding groove is slidably installed inside the sliding groove.

[0012] Preferably, stable sliding grooves are formed on both inner walls of the sliding groove. A stable sliding block is slidably installed inside the stable sliding groove. One side of the stable sliding block close to the sliding block is connected to the sliding block.

[0013] Preferably, the detection mechanism includes a spring telescopic rod and a pressure sensor. The pressure sensor is installed at the top end of the inner wall of the sliding groove. The spring telescopic rod is installed on one side of the sliding block close to the pressure sensor. One end of the spring telescopic rod close to the pressure sensor abuts against the pressure sensor.

[0014] The beneficial effects of the present invention are as follows:

[0015] In the present invention, by providing a protective cover installed outside the output motor of the mud pump, the output motor of the mud pump can be protected, preventing debris at the work site from falling and damaging the output motor of the mud pump. At the same time, during the use of the device, it can protect the output motor of the mud pump from rain and oil, and prevent mud from entering the output motor of the mud pump when the mud pump body is in use, thus ensuring the stable operation of the overall function of the device.

[0016] In the present invention, by providing an electric telescopic rod, a connecting member and an abutting roller, when the staff disassembles the protective cover, the rotating block moves to the use position outside the output motor of the mud pump, and then the two rotating blocks clamp and fix the outside of the output motor of the mud pump. Through this operation method, when the staff disassembles the protective cover, the sudden drop of the protective cover caused by operation errors can be avoided, protecting the work safety of the staff. When installing the protective cover, the same operation method can be adopted, greatly improving the safety of the staff during the disassembly and installation of the protective cover.

[0017] The rotating block moves to the outside of the output motor of the mud pump. Through the movement of the rotating block outside the output motor of the mud pump, the temperature sensor can detect the operating temperature at different positions of the output motor of the mud pump, and transmit the measured data to the background control system for comparison with the standard temperature value. Through this operation method, the detection of the operating temperature of the output motor of the mud pump can be realized, and its mobile detection method enables the device to detect different operating positions of the output motor of the mud pump, enabling the staff to quickly and accurately formulate a maintenance plan based on the detection results.

[0018] Through the movement of the connecting piece and the rotating block, the end of the rotating block away from the abutting roller can abut against the outside of the output motor of the mud pump. At this time, the vibration generated during the operation of the output motor of the mud pump will be transmitted to the rotating block, and the vibration sensor transmits the measured vibration value to the background control system and compares it with its standard vibration value. Through this operation method, the abnormal use of the output motor of the mud pump can be detected when the output motor of the mud pump initially fails, and the staff can be notified to carry out repairs as soon as possible to prevent the output motor of the mud pump from working in an abnormal state for a long time, causing complete damage to the output motor of the mud pump and affecting the normal use of the device.

[0019] When it is necessary to detect the deformation of the protective cover, the abutting roller abuts against the inner wall of the protective groove, and then the abutting roller rolls while abutting against the inner wall of the protective groove. When the abutting roller is squeezed, the sliding block will slide into the inside of the sliding groove, and the sliding block squeezes the spring telescopic rod, and the spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system and compares it with its standard pressure value. Through this operation method, the deformation detection of the protective cover can be completed to prevent the damage of its use function due to its own deformation during use.

[0020] When it is necessary to detect the installation stability of the protective cover, by extending the electric telescopic rod, one rotating block abuts against the side wall of the mud pump body inside the protective cover, and the abutting roller on the other rotating block abuts against the side wall of the mud pump body inside the protective cover. The pressure sensor measures the pressure value at this time and transmits it to the background control system. Then, the electric telescopic rod connected to the mud pump body where the rotating block abuts extends. During its extension, the background control system monitors the change in the pressure value measured by the pressure sensor. If the change in the pressure value exceeds the preset pressure value change range, it indicates that the installation between the protective cover and the mud pump body is loose. At this time, the staff immediately tightens it according to the detection results to ensure the functional use stability of the device. Description of the Drawings

Specific embodiments

[0030] The following will describe in detail the embodiments of the technical solutions of the present invention with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0031] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

[0032] Such as Figures 1-7As shown in the figure, a protective housing for an F-type mud pump used in petrochemical industry includes a mud pump body 1. A mud pump output motor 3 is provided on the mud pump body 1. A protective cover 2 is provided outside the mud pump output motor 3. A protective groove 4 is opened on the protective cover 2. One side of the protective cover 2 close to the mud pump body 1 is connected to the mud pump body 1. The mud pump output motor 3 is located inside the protective groove 4, and an auxiliary mechanism is provided inside the protective groove 4. The way the protective cover 2 is installed outside the mud pump output motor 3 can protect the mud pump output motor 3. At the same time, during the use of the device, it can also play the role of rain protection and oil protection for the mud pump output motor 3, and can also prevent mud from entering the mud pump output motor 3 when the mud pump body 1 is in use, causing damage to the mud pump output motor 3, thereby ensuring the stability of the overall function operation of the device. The auxiliary mechanism can complete various function detections of the device during the use of the device, ensuring the stability of the function operation of the device.

[0033] As a technical optimization scheme of the present invention, the auxiliary mechanism includes a movable plate 5 and a rotating block 12. Two movable plates 5 are movably installed at the top end of the inner wall of the protective groove 4. One side of the movable plate 5 away from the top end of the inner wall of the protective groove 4 is movably connected to a connecting piece 11, and a rotating block 12 is movably installed inside the connecting piece 11. The movement of the movable plate 5 can drive the corresponding movement of the connecting piece 11 and the rotating block 12.

[0034] As a technical optimization scheme of the present invention, a vibration sensor 16 is installed on one side of the rotating block 12, a temperature sensor 17 is installed on the other side of the rotating block 12, and a rotating motor 15 is installed on the side wall of the connecting piece 11. The output end of the rotating motor 15 movably penetrates the side wall of the connecting piece 11 and is connected to the rotating block 12. The rotating motor 15 can drive the rotating block 12 to rotate, thereby realizing the autonomous switching of various usage functions on the rotating block 12. The temperature sensor 17 can detect the operating temperature of the mud pump output motor 3, and the vibration sensor 16 can detect the vibration during the operation of the mud pump output motor 3. By comparing the detection results of the two, the detection of the operating state of the mud pump output motor 3 can be completed.

[0035] As a technical optimization scheme of the present invention, an annular chute 6 is opened at the top end of the inner wall of the protective groove 4. An annular electric slider 7 is installed on one side of the movable plate 5 close to the annular chute 6. The annular electric slider 7 is slidably installed inside the annular chute 6. The sliding of the annular electric slider 7 in the annular chute 6 can drive the movable plate 5 to move inside the protective groove 4.

[0036] As a technical optimization solution of the present invention, a moving chute 8 is provided on one side of the movable plate 5 away from the top end of the inner wall of the protection groove 4. A moving electric slider 9 is slidably installed inside the moving chute 8, and one side of the moving electric slider 9 close to the connecting member 11 is connected to the connecting member 11. By sliding the moving electric slider 9 in the moving chute 8, the electric telescopic rod 10 can be driven to move on the movable plate 5.

[0037] As a technical optimization solution of the present invention, an electric telescopic rod 10 is installed on one side of the moving electric slider 9 close to the connecting member 11. The telescopic end of the electric telescopic rod 10 faces the connecting member 11, and the telescopic end of the electric telescopic rod 10 is connected to the connecting member 11. The electric telescopic rod 10 can drive the connecting member 11 to extend.

[0038] As a technical optimization solution of the present invention, a sliding block 13 is movably installed at one end of the rotating block 12 away from the connecting member 11. An abutting roller 14 is rotatably installed at one end of the sliding block 13 away from the connecting member 11, and a detection mechanism is provided at one end of the sliding block 13 close to the rotating block 12. The combination of the abutting roller 14 and the detection mechanism can realize various function detections of the protective cover 2.

[0039] As a technical optimization solution of the present invention, a sliding groove 18 is provided at one end of the rotating block 12 away from the connecting member 11. One end of the sliding block 13 close to the sliding groove 18 is slidably installed inside the sliding groove 18;

[0040] Stable sliding grooves 20 are provided on the inner walls on both sides of the sliding groove 18. A stable slider 21 is slidably installed inside the stable sliding grooves 20, and one side of the stable slider 21 close to the sliding block 13 is connected to the sliding block 13. By sliding the stable slider 21 inside the stable sliding grooves 20, the sliding stability of the sliding block 13 inside the sliding groove 18 can be increased.

[0041] As a technical optimization solution of the present invention, the detection mechanism includes a spring telescopic rod 22 and a pressure sensor 19. The pressure sensor 19 is installed at the top end of the inner wall of the sliding groove 18. A spring telescopic rod 22 is installed on one side of the sliding block 13 close to the pressure sensor 19. One end of the spring telescopic rod 22 close to the pressure sensor 19 abuts against the pressure sensor 19. When it is necessary to detect the deformation of the protective cover 2, the abutting roller 14 can abut against the inner wall of the protective groove 4. Subsequently, through the sliding of the annular electric slider 7 in the annular sliding groove 6, the abutting roller 14 rolls while abutting against the inner wall of the protective groove 4. When the abutting roller 14 is squeezed, the sliding block 13 slides into the interior of the sliding groove 18, and the sliding block 13 squeezes the spring telescopic rod 22, and the spring telescopic rod 22 squeezes the pressure sensor 19. The pressure sensor 19 transmits the measured pressure value to the background control system and compares it with the standard pressure value. Through this operation method, the deformation detection of the protective cover 2 can be completed to prevent the impairment of its use function due to its own deformation during use;

[0042] When it is necessary to detect the installation stability of the protective cover 2, one rotating block 12 abuts against the side wall of the mud pump body 1 inside the protective cover 2, and the abutting roller 14 on the other rotating block 12 abuts against the side wall of the mud pump body 1 inside the protective cover 2. The pressure sensor 19 measures the pressure value at this time and transmits it to the background control system. Subsequently, the electric telescopic rod 10 connected to the mud pump body 1 abutted by the rotating block 12 extends. During its extension process, the background control system monitors the change of the pressure value measured by the pressure sensor 19. If the change of the pressure value exceeds the preset pressure value change range, it indicates that the installation of the protective cover 2 is loose. At this time, the staff immediately tightens it according to the detection result to ensure the functional use stability of the device.

[0043] When the present invention is in use, the electrical equipment used in the device is powered by connecting to an external power source through wires. The device controls the electrical equipment in the device by presetting a control system. The mud pump body 1 and the mud pump output motor 3 used in the device are both existing mature technologies, so no more elaboration will be made on them. When the protective cover 2 is in use, it is fixedly installed with the mud pump body 1 by tightening bolts and sleeved outside the mud pump output motor 3. The pressure sensor 19, vibration sensor 16 and temperature sensor 17 used in the device are all existing mature technologies, so no more elaboration will be made on them.

[0044] The way the protective cover 2 is installed outside the mud pump output motor 3 can protect the mud pump output motor 3. At the same time, during the use of the device, it can also protect the mud pump output motor 3 from rain and oil, and prevent mud from entering the mud pump output motor 3 when the mud pump body 1 is in use, thus damaging the mud pump output motor 3, and ensuring the stable operation of the overall function of the device.

[0045] When the staff disassemble the protective cover 2, by sliding the moving electric slider 9 in the moving chute 8, the two electric telescopic rods 10 are respectively moved to the use positions on both sides of the mud pump output motor 3. Subsequently, by rotating the motor 15 to drive the rotating block 12 to rotate, the ends of the two rotating blocks 12 far from the abutting roller 14 are rotated to the side facing each other. Then, the electric telescopic rod 10 drives the connecting piece 11 to extend, so that the rotating block 12 moves to the use position outside the mud pump output motor 3. Then, by sliding the moving electric slider 9 in the moving chute 8, the two rotating blocks 12 clamp and fix the outside of the mud pump output motor 3. Through this operation method, when the staff disassemble the protective cover 2, the sudden drop of the protective cover 2 will not be caused by operation errors, which plays a role in protecting the work safety of the staff. When installing the protective cover 2, the same operation method can be adopted, which greatly improves the safety of the staff during the disassembly and assembly of the protective cover 2.

[0046] During the use of the device, the rotating block 12 moves to the outside of the mud pump output motor 3, and through the movement of the rotating block 12 outside the mud pump output motor 3, the temperature sensor 17 can detect the use temperature of different positions of the mud pump output motor 3, and transmit the measured data to the background control system for comparison with the standard temperature value. Through this operation method, the detection of the use temperature of the mud pump output motor 3 can be realized, and the way of moving detection can enable the device to detect different use positions of the mud pump output motor 3, so that the staff can quickly and accurately formulate a maintenance plan according to the detection results.

[0047] When the device is in use, through the movement of the connecting member 11 and the rotating block 12, one end of the rotating block 12 away from the abutting roller 14 can abut against the outer side of the mud pump output motor 3. At this time, the vibration generated when the mud pump output motor 3 operates will be transmitted to the rotating block 12, and the vibration sensor 16 transmits the measured vibration value to the background control system and compares it with its standard vibration value. Through this operation method, the abnormal use of the mud pump output motor 3 can be detected when the mud pump output motor 3 initially has a fault, and the staff can be notified to carry out maintenance as soon as possible to prevent the mud pump output motor 3 from working in an abnormal state for a long time, causing complete damage to the mud pump output motor 3 and affecting the normal use of the device.

[0048] When it is necessary to detect the deformation of the protective cover 2, by rotating the rotating motor 15 to drive the rotating block 12 to rotate, the abutting roller 14 is rotated to face the inner wall of the protective cover 2. Then, by sliding the moving electric slider 9 in the moving chute 8, the abutting roller 14 can abut against the inner wall of the protective groove 4. Subsequently, by sliding the annular electric slider 7 in the annular chute 6, the abutting roller 14 rolls while abutting against the inner wall of the protective groove 4. When the abutting roller 14 is squeezed, the sliding block 13 will slide into the interior of the sliding groove 18, and the sliding block 13 squeezes the spring telescopic rod 22, and the spring telescopic rod 22 squeezes the pressure sensor 19. The pressure sensor 19 transmits the measured pressure value to the background control system and compares it with the standard pressure value. Through this operation method, the deformation detection of the protective cover 2 can be completed to prevent the impairment of its use function due to its own deformation during use.

[0049] When it is necessary to detect the installation stability of the protective cover 2, at this time, the abutting roller 14 on one rotating block 12 rotates to a use state away from the bottom end of the inner wall of the protection groove 4, and the abutting roller 14 on the other rotating block 12 rotates to a use state facing the bottom end of the inner wall of the protection groove 4. Through the movement of the movable plate 5 in the protection groove 4, the two rotating blocks 12 both move to the preset use positions. Subsequently, by extending the electric telescopic rod 10, one rotating block 12 abuts against the side wall of the mud pump body 1 inside the protective cover 2, and the abutting roller 14 on the other rotating block 12 abuts against the side wall of the mud pump body 1 inside the protective cover 2. Then, the pressure sensor 19 measures the pressure value at this time and transmits it to the background control system. Subsequently, the electric telescopic rod 10 connected to the mud pump body 1 abutted by the rotating block 12 extends. During its extension process, the background control system monitors the change in the pressure value measured by the pressure sensor 19. If the change in the pressure value exceeds the preset pressure value change range, it indicates that the installation between the protective cover 2 and the mud pump body 1 is loose. By rotating the movable plate 5, the device can detect the protective cover 2 from multiple angles, thereby increasing the accuracy of the detection results. At this time, the staff immediately tightens it according to the detection results, so as to ensure the functional use stability of the device.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
