Description

Technical Field

[0001] The present invention relates to the technical field of water level monitoring, and particularly to a semi-automatic pumping test water level monitoring device for complex strata. Background Art

[0002] When conducting a semi-automatic pumping test, it is necessary to use a monitoring device to monitor the water level so that an alarm can be issued when the water level changes, facilitating timely reminder to relevant personnel to take measures.

[0003] When monitoring the water level, when monitoring in rock fractures or at the water level outcrop where well construction is not possible or in wells with a small monitoring well diameter, the monitoring head is easily stuck inside the fracture or well pipe. Forcefully pulling out the monitoring head easily causes damage or even loss of the monitoring head, which not only increases the cost of water level monitoring, but also easily causes loss of data, and at the same time affects the monitoring efficiency. The lost monitoring head needs to be searched and salvaged manually, consuming a large amount of manpower and material resources, and there are also certain safety hazards. Summary of the Invention

A monitoring head is arranged inside the frame. The monitoring head is connected to the frame through a rotating mechanism. A support frame is arranged outside the frame. The support frame is connected to the frame through an adjusting mechanism. Two groups of brushes are arranged between the support frame and the frame. The brushes are in contact with the outer surface of the frame. The brushes are connected to the support frame through a connecting component.

[0006] Preferably, the rotating mechanism includes a rotatable rotating shaft. The rotating shaft is arranged inside the frame. The rotating shaft is arranged vertically. A support block is fixedly installed on the outer surface of the rotating shaft. One end of the support block away from the rotating shaft is fixedly connected to the monitoring head.

[0007] Preferably, an installation frame is fixedly installed inside the frame. A motor is fixedly installed inside the installation frame. The output end of the motor penetrates through the installation frame and extends below the installation frame. The output end of the motor is fixedly connected to the rotating shaft.

[0008] Preferably, the adjusting mechanism includes a cross plate. The cross plate is arranged at the bottom of the frame. The cross plate is connected to the rotating shaft through a power component. The cross plate is slidably connected to the support frame.

[0009] Preferably, the power assembly includes a bottom plate and an adjusting plate. The bottom plate is rotatably installed at the bottom of the frame, and the bottom plate is fixedly connected to the rotating shaft. The adjusting plate is rotatably inserted into the frame with damping. An activity groove is formed at the edge of the bottom plate, and the activity groove is slidably connected to the cross plate. A guide groove is formed at the edge of the adjusting plate, and a connecting member is slidably inserted into the guide groove. The connecting member is fixedly connected to the cross plate.

[0010] Preferably, the adjusting plate is designed in a circular ring shape. Two fixing blocks are fixedly installed at the center of the adjusting plate. A pushing block is arranged between the two fixing blocks, and the pushing block is fixedly connected to the rotating shaft.

[0011] Preferably, the connecting assembly includes a fixing plate and a connecting plate. The fixing plate is fixedly connected to the brush. One end of the connecting plate is rotatably connected to the fixing plate, and the other end of the connecting plate is rotatably connected to the support frame through a torsion spring.

[0012] Preferably, guide blocks are rotatably installed at both the upper and lower ends of the fixing plate. A guide rail is fixedly installed outside the frame, and the guide rail is slidably connected to the guide blocks.

[0013] Preferably, a shaft member is rotatably inserted into the support frame. An installation plate is fixedly sleeved outside the shaft member. A ball is rotatably installed on the side of the installation plate away from the frame. A blade is fixedly installed on the side of the installation plate away from the ball.

[0014] Preferably, a gear is fixedly sleeved outside the shaft member. A convex block is fixedly installed inside the support frame. A cross bar movably penetrates through the convex block. A rack is fixedly installed outside the cross bar. The rack meshes with the gear. A spring is movably sleeved outside the cross bar, and the spring is fixedly connected to the convex block.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. By setting the motor, when the motor rotates forward, the motor can drive the brush and the monitoring head to rotate, so that the brush can clean the outer surface of the frame, and the monitoring angle of the monitoring head is more comprehensive, making the monitoring result more perfect. When the motor rotates in reverse, it can drive the support frame to move towards the frame, reducing the overall size of the device, so that the device can be taken out when it is stuck inside a crack or a well pipe.

[0017] 2. By setting up the support frame and the brush, when the device enters the crack or the inside of the well pipe, the rocks on both sides of the crack or the well pipe can squeeze the support frame, so that the frame will not get stuck inside the crack or the well pipe. When the frame is completely stuck inside the crack or the well pipe and cannot move, the size of the device can be further adjusted by reversing the motor, so that the device will not get stuck inside the crack or the well pipe.

[0018] 3. By setting up the ball bearings and the blades, through the interchange of the positions of the ball bearings and the blades, in the initial state, the ball bearings can reduce the impact on aquatic animals during the monitoring process. When the device is in the contracted state, the ball bearings are in contact with the outer surface of the frame. The ball bearings can reduce the friction between the support frame and the frame, playing a certain protective role for the frame. At the same time, the blades can cut the vegetation roots in the crack water to prevent the vegetation roots in the water from entangling the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Please refer to Figures 1-8 , a semi-automatic pumping test water level monitoring device for a complex formation shown in the figure, including a frame 1.

This is a commonly used monitoring method in the prior art, and the corresponding design of the host end and the program is the prior art, so no more details will be described.

[0030] Specifically, the rotating mechanism includes a rotatable rotating shaft 3. The rotating shaft 3 is arranged inside the frame 1. The rotating shaft 3 is arranged vertically. A support block 6 is fixedly installed on the outer surface of the rotating shaft 3. One end of the support block 6 away from the rotating shaft 3 is fixedly connected to the monitoring head 5.

[0031] An installation frame 2 is fixedly installed inside the frame 1. A motor 4 is fixedly installed inside the installation frame 2. The output end of the motor 4 penetrates through the installation frame 2 and extends below the installation frame 2. The output end of the motor 4 is fixedly connected to the rotating shaft 3.

[0032] Further, the adjusting mechanism includes a cross plate 12. The cross plate 12 is arranged at the bottom of the frame 1. The cross plate 12 is connected to the rotating shaft 3 through a power component. The cross plate 12 is slidably connected to the support frame 15.

[0033] The power component includes a bottom plate 7 and an adjusting plate 8. The bottom plate 7 is rotatably installed at the bottom of the frame 1. The bottom plate 7 is fixedly connected to the rotating shaft 3. The adjusting plate 8 is rotatably inserted into the frame 1 with damping. An activity groove 9 is formed at the edge of the bottom plate 7. The activity groove 9 is slidably connected to the cross plate 12. A guide groove 10 is formed at the edge of the adjusting plate 8. A connecting piece 11 is slidably inserted into the guide groove 10. The connecting piece 11 is fixedly connected to the cross plate 12.

[0034] Further, the adjusting plate 8 is designed in a circular ring shape. Two fixing blocks 14 are fixedly installed at the center of the adjusting plate 8. A pushing block 13 is arranged between the two fixing blocks 14, and the pushing block 13 is fixedly connected to the rotating shaft 3.

[0035] The connecting assembly includes a fixing plate 16 and a connecting plate 18. The fixing plate 16 is fixedly connected to the brush 17. One end of the connecting plate 18 is rotatably connected to the fixing plate 16, and the other end of the connecting plate 18 is rotatably connected to the support frame 15 through a torsion spring 21.

[0036] Guide blocks 20 are rotatably installed at both the upper and lower ends of the fixing plate 16. A guide rail 19 is fixedly installed outside the frame 1, and the guide rail 19 is slidably connected to the guide blocks 20.

[0037] A shaft member 25 is rotatably inserted inside the support frame 15. An installation plate 22 is fixedly sleeved outside the shaft member 25. A ball 23 is rotatably installed on the side of the installation plate 22 away from the frame 1, and a blade 24 is fixedly installed on the side of the installation plate 22 away from the ball 23.

[0038] Further, a gear 26 is fixedly sleeved outside the shaft member 25. A convex block 28 is fixedly installed inside the support frame 15. A cross bar 29 movably penetrates through the convex block 28. A rack 27 is fixedly installed outside the cross bar 29, and the rack 27 meshes with the gear 26. A spring 30 is movably sleeved outside the cross bar 29, and the spring 30 is fixedly connected to the convex block 28.

[0039] Working principle: The frame 1 is connected to the monitoring device. The frame 1 is placed in water. Under the action of the mounting bracket 2, the motor 4 drives the support block 6 and the monitoring head 5 to rotate through the rotating shaft 3. When the monitoring head 5 rotates, it can monitor the water level from multiple angles, and the monitoring results are more comprehensive.

[0040] The rotating shaft 3 can drive the bottom plate 7 to rotate synchronously. At this time, the cross plate 12 slidably installed on the bottom plate 7 can drive the support frame 15 to rotate. Under the action of the connecting assembly, the support frame 15 drives the brush 17 to move through the fixing plate 16. At this time, the guide block 20 moves along the guide rail 19, and the brush 17 contacts the outer surface of the frame 1. The brush 17 can clean the outer surface of the frame 1, and can prevent impurities in the water from adhering to the outer surface of the frame 1, which is beneficial to ensuring the monitoring effect of the monitoring head 5.

[0041] In the initial state, the ball 23 is located on the side of the installation plate 22 away from the frame 1, so that when the device contacts the animals in the water, it will not cause harm to the animals in the water. During the monitoring process, when encountering a crack, the support frame 15 is squeezed. The support frame 15 drives the two fixing plates 16 and the brush 17 to move away from each other through the connecting plate 18. At this time, the torsion spring 21 is deformed.

[0042] Further, when the device gets stuck inside the crack and cannot move, the motor 4 drives the bottom plate 7 to rotate in the opposite direction. At this time, under the cooperation of the movable groove 9 and the guide groove 10 opened on the adjusting plate 8, the bottom plate 7 drives the cross plate 12 and the connecting piece 11 to move. At this time, the connecting piece 11 moves inside the guide groove 10. At the same time, the connecting piece 11 drives the cross plate 12 to move towards the center of the bottom plate 7.

[0043] At the same time, the support frame 15 moves towards the frame 1. At this time, the support frame 15 pushes the two fixed plates 16 away from each other through the connecting plate 18. As the support frame 15 continues to move towards the frame 1, the frame 1 contacts the rack 27. The rack 27 drives the cross bar 29 to move inside the bump 28. At this time, the spring 30 deforms under force. The rack 27 meshes with the gear 26. The rack 27 can drive the shaft member 25 to rotate through the gear 26. The shaft member 25 drives the mounting plate 22 to rotate 180 degrees. At this time, the ball 23 contacts the frame 1, which can reduce the friction of the support frame 15 on the frame 1, thereby reducing the damage to the outer surface of the frame 1. The blade 24 is located on the side of the mounting plate 22 away from the frame 1. The blade 24 can cut the root systems of the aquatic plants in the water, so that the root systems of the aquatic plants will not wrap around the outside of the frame 1, facilitating the removal of the device from the inside of the crack.

[0044] It should be noted that the friction between the adjusting plate 8 and the frame 1 is much greater than the friction between the bottom plate 7 and the frame 1. When the connecting piece 11 moves to the end inside the guide groove 10 and cannot move anymore, at this time, the push block 13 is connected to one of the fixed blocks 14, so that the rotating shaft 3 can drive the bottom plate 7 and the adjusting plate 8 to rotate synchronously.

[0045] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.
