Probe arrangement support and tube well water quality monitoring system

Abstract

This application provides a probe mounting bracket and a well water quality monitoring system. The probe mounting bracket includes a main section and a main section fixing section. The main section fixing section can axially lock the main section, limiting its axial displacement. The main section fixing section also includes multiple fixing arms and auxiliary arms that can radially expand or retract from the main section to limit its radial displacement. One end of the auxiliary arm is hinged to the fixing arm; lifting the other end of the auxiliary arm allows the probe mounting bracket to be lifted. When the height of the top of the fixing arm remains unchanged, lowering the other end of the auxiliary arm allows the fixing arm to expand and abut against the well wall; raising the other end of the auxiliary arm allows the fixing arm to retract, releasing the fixing relationship between the main section and the well. With the fixing arm fixed to the well wall, lifting the auxiliary arm simultaneously retracts the fixing arm and lifts the probe mounting bracket. The well water quality monitoring system includes the aforementioned probe mounting bracket.

Description

Technical Field

[0001] This application relates to the field of well water quality monitoring, and in particular to probe deployment supports and well water quality monitoring systems. Background Technology

[0002] In urban manholes, the depth varies greatly, with shallow wells less than 2 meters deep and deep wells reaching 10 meters deep. It is extremely difficult to install and deploy monitoring equipment in deep wells.

[0003] Currently, the most common method for installing monitoring equipment is to suspend the probe of the monitoring equipment into the well using a long steel wire rope for in-situ measurement. However, due to the impact of the sewage flow and the disturbance of vortices inside the well, the probe is prone to rotation and swinging. Moreover, the longer the rope, the greater the swing amplitude, which can easily lead to rope breakage due to stress, and may also cause the probe to be unstable and unable to meet the monitoring requirements.

[0004] Another method to fix the probe to the bottom of the well is to manually lower it into the well for installation. However, for sewage wells and deep wells, manual installation requires professional personnel and specialized equipment, and also poses significant safety hazards. Summary of the Invention

[0005] In order to improve or solve at least one of the problems mentioned in the background art, this application provides a probe deployment bracket and a well water quality monitoring system.

[0006] The probe deployment bracket provided in this application embodiment is used to deploy probes in a well. The probe deployment bracket includes:

[0007] The main part is used to limit the swing of the probe of the monitoring equipment; and

[0008] The main fixing part is capable of axially locking the main part to restrict its axial displacement. It also includes multiple fixing arms and auxiliary arms that can radially expand or contract to further restrict radial displacement. One end of each auxiliary arm is hinged to a fixing arm, and the auxiliary arm has an axial limiting relationship with the main part. Lifting the other end of the auxiliary arm allows the probe deployment bracket to be lifted.

[0009] When the height of the top of the fixed arm remains unchanged, lowering the other end of the auxiliary arm allows the fixed arm to extend and contact the well wall, thereby fixing the position of the main component within the well. Raising the other end of the auxiliary arm allows the fixed arm to retract, releasing the fixation between the main component and the well.

[0010] With the fixed arm fixed to the well wall, lifting the auxiliary arm can simultaneously retract the fixed arm and lift the probe deployment bracket.

[0011] In at least one embodiment, the main fixing part further includes:

[0012] A first flange, slidably disposed on the main portion, and the other end of the fixing arm hinged to the first flange; and

[0013] The second flange is slidably disposed on the main part.

[0014] The auxiliary arm is hinged to one end of the fixed arm, which is lower than the other end of the auxiliary arm hinged to the second flange.

[0015] In at least one embodiment, the main part is provided with a first stop and a second stop that are spaced apart axially, and the first flange and the second flange are slidably disposed between the first stop and the second stop, and their movement range is limited by the first stop and the second stop.

[0016] In at least one embodiment, the main portion includes a first large-diameter portion, a first small-diameter portion, and a second large-diameter portion arranged sequentially in the axial direction. The first large-diameter portion is the first stop portion, and the second large-diameter portion is the second stop portion. The first flange and the second flange are slidably disposed on the first small-diameter portion.

[0017] The second flange is connected to a suspension part. When the suspension part is lifted and the first flange is not restricted in height by a device other than the first stop part, the distance between the first flange and the second flange becomes smaller, the first flange abuts against the first large diameter part, and the fixed arm retracts radially inward.

[0018] In at least one embodiment, a lock hole is provided on the first minor diameter portion, and a remotely retractable locking tongue is provided on the first flange. The locking tongue extends into the lock hole to achieve relative fixation between the first flange and the first minor diameter portion. When the first flange is fixed relative to the first minor diameter portion, there is a set distance between the first flange and the first major diameter portion. The second flange abuts against the second major diameter portion, and the fixing arm retracts radially inward.

[0019] In at least one embodiment, the main fixing part further includes a telescopic member, one end of which is hinged to the fixing arm, and the other end of which is hinged to the second flange.

[0020] When the latch is inserted into the lock hole, the telescopic member is under pressure. After the latch leaves the lock hole, the telescopic member can extend to increase the distance between the first flange and the second flange, thereby opening the fixed arm.

[0021] In at least one embodiment, the hinge point where the auxiliary arm is hinged to the fixed arm is the auxiliary arm-fixed arm hinge point.

[0022] The hinge point between the first flange and the fixed arm is the first flange fixed arm hinge point, and the hinge point between the second flange and the auxiliary arm is the second flange auxiliary arm hinge point.

[0023] In the axial direction of the main part, the hinge point of the second flange auxiliary arm is located between the hinge point of the auxiliary arm fixed arm and the hinge point of the first flange fixed arm, such that when the second flange is close to the first flange, the fixed arm retracts radially inward.

[0024] In at least one embodiment, the fixed arm further includes a fixed arm body and a pawl hinged to the fixed arm body for abutting against the well wall.

[0025] The pawl is provided with a first spike, a second spike, and an auxiliary wheel in sequence. The second spike protrudes more than the first spike, so that when the pawl descends and abuts against the well wall, the pawl tilts, thereby causing both the first spike and the second spike to abut against the well wall, and causing the auxiliary wheel to move away from the well wall.

[0026] In at least one embodiment, in the arrangement direction of the first spike, the second spike, and the auxiliary wheel, the distance L1 between the tip of the second spike and the tip of the first spike is equal to the distance L2 between the tip of the second spike and the center of the auxiliary wheel, and the rotation center of the pawl hinged to the fixed arm body is located between the tips of the first spike and the tips of the second spike.

[0027] In at least one embodiment, the main part is a sleeve, the probe includes a monitoring end and a non-monitoring end, the non-monitoring end is located in the sleeve, the non-monitoring end can abut against the inner wall of the sleeve to limit the swing of the probe, and the monitoring end extends out of the sleeve.

[0028] In at least one embodiment, the main part is a solid shaft, and the probe is connected to one end of the solid shaft.

[0029] The well water quality monitoring system provided in this application is used to monitor the water quality in the monitoring area of ​​a well. The well water quality monitoring system includes:

[0030] The probe mounting bracket as described above; and

[0031] A monitoring device, comprising the probe, the probe being connected to the main unit.

[0032] The probe deployment bracket provided in this application includes a main body and a sleeve fixing part that can fix the main body to the well wall. The probe fixing part includes a fixed arm and an auxiliary arm. The fixing and unfixation with the well wall are achieved by opening and closing the fixed arm. When the height of the top of the fixed arm remains unchanged, the auxiliary arm descends to open the fixed arm; the auxiliary arm rises to retract the fixed arm. Unlike the conventional umbrella-shaped opening and closing structure, there is also an axial limiting relationship between the auxiliary arm and the main body, which facilitates the simultaneous release of the fixing arm from the well wall and the lifting of the probe deployment bracket when the other end of the auxiliary arm is lifted, making it more convenient to use.

[0055] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features shown. In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0056] Example 1

[0057] See Figure 1 The probe placement bracket provided in this application is used to place a probe in a well 1. The probe placement bracket may include a main part 2 and a main part fixing part 3. The main part 2 is used to limit the swing of the probe 4 of the monitoring device. The main part fixing part 3 can axially lock the main part 2 to limit its axial displacement, and the main part fixing part 3 also includes multiple fixing arms 31 and auxiliary arms 35 that are radially expanded or contracted in the main part 2 to limit its radial displacement. One end of the auxiliary arm 35 is hinged to one end of the fixing arm 31. The other end of the auxiliary arm 35 has an axial limiting relationship with the main part 2, and the probe placement bracket can be lifted by lifting the other end of the auxiliary arm 35. Optionally, the other end of the auxiliary arm 35 can be slidably connected to the main part 2.

[0058] With the height of the top end of the fixed arm 31 remaining constant, lowering the other end of the auxiliary arm 31 (i.e., increasing the distance between the top end of the fixed arm 31 and the other end of the auxiliary arm 31) allows the fixed arm 31 to open and abut against the well wall of the well 1, thereby fixing the position of the main part 2 in the well 1. Raising the other end of the auxiliary arm 31 (i.e., decreasing the distance between the top end of the fixed arm 31 and the other end of the auxiliary arm 31) allows the fixed arm 31 to retract, thus releasing the fixation between the main part 2 and the well 1. This ensures that when the fixed wall 31 is fixed to the well wall, the action of lifting the auxiliary arm 35 simultaneously retracts the fixed arm 31 and lifts the probe deployment bracket.

[0059] The main part 2 can be a hollow sleeve or a solid shaft. When the main part 2 is a sleeve, the probe 4 of the monitoring device can pass through the main part 2 and enter the monitoring area 5 in the well 1. The probe suspension rope for suspending the probe 4 or the probe 4 itself can abut against the inner wall of the main part 2 to limit the swing of the probe 4. The probe 4 can include a monitoring end and a non-monitoring end. The non-monitoring end can be located in the sleeve and abut against the inner wall of the sleeve to limit the swing of the probe 4. The monitoring end can extend out of the sleeve.

[0060] Compared to existing technologies that directly suspend the probe into the well, this application provides a main part 2 fixed to the well wall outside the probe 4 and the probe suspension rope, which reduces the possibility of breakage of the probe suspension rope due to violent swinging and meets the monitoring stability requirements of the probe 4.

[0061] In another embodiment, the main body is a solid shaft, allowing the probe 4 to be directly fixed to the end of the main body 2. This eliminates the need for a probe suspension rope. The connecting rope, which serves as the power and signal cable, can be fixed to the side wall of the shaft structure (either located on the outside of the side wall or embedded in a groove on the side wall). This also helps prevent the probe 4 from swinging. The probe 4 and main body 2 can be fixed outside the well first, and then the entire assembly can be lowered into the well.

[0062] In contrast, in the embodiment where the main part 2 is a sleeve, the probe 4 does not need to be fixed to the main part 2, allowing for quick retrieval of the probe 4 during maintenance by directly lifting it. The method of having the probe suspension rope pass through the sleeve into the monitoring area 5 within the manhole 1 avoids contact between the rope and water in the manhole 1 due to splashing or other reasons, thus protecting the rope. Furthermore, installation is convenient; the probe mounting bracket can be installed inside the manhole first and fixed relative to the manhole wall before the probe is lowered into the manhole from the main part 2 (sleeve). Similarly, the probe can be retrieved first during retrieval, reducing damage during installation.

[0063] It should be understood that monitoring area 5 can be the area represented by a certain height range in well 1.

[0064] Further, see Figures 2 to 5 The main fixing part 3 may further include a first flange 33 and a second flange 34. The first flange 33 is slidably disposed on the main part 2, and the other end of the fixing arm 31 is hinged to the first flange 33. The second flange 34 is slidably disposed on the main part 2. The first flange 33 and the second flange 34 can rotate relative to the main part 2. The other end of the auxiliary arm 35 is hinged to the second flange 34.

[0065] The degree of extension of the fixed arm 31 can be adjusted by changing the distance between the first flange 33 and the second flange 34. Therefore, by using this structure, combined with existing methods for controlling the distance between the first flange 33 and the second flange 34, the extension and retraction of the fixed arm 31 can be achieved. For example, a telescopic linear motion mechanism can be connected to the first flange 33 and the second flange 34, and the telescopic extension and retraction of the linear motion mechanism can be remotely controlled to adjust the distance between the first flange 33 and the second flange 34.

[0066] Alternatively, the main part 2 may further include a first stop and a second stop that are spaced apart axially. The first flange 33 and the second flange 34 are slidably disposed between the first stop and the second stop, and their range of movement is limited by the first stop and the second stop to satisfy the axial limiting relationship between the other end of the auxiliary arm 35 and the main part.

[0067] See Figure 2 , Figure 5The main part 2 may include a first large-diameter part 21, a first small-diameter part 22, and a second large-diameter part 23 arranged sequentially in the axial direction. The first large-diameter part 21 may be a first stop, and the second large-diameter part 23 may be a second stop. The first flange 33 and the second flange 34 are slidably disposed on the first small-diameter part 22, so that the movement range of the flanges is limited to the first small-diameter part 22. For example, the first flange 33 can abut against the first large-diameter part 21 after being raised relative to the first small-diameter part 22, and the second flange 34 can abut against the second large-diameter part 23 after being lowered relative to the first small-diameter part 22.

[0068] For example, the main part 2 can be a sleeve, which can be formed by splicing sleeves of different diameters to form the aforementioned large-diameter part and small-diameter part. The different diameter sleeves can be made by welding steel pipes, fusion or bonding plastic pipes, etc. Of course, the main part 2 can also include a second small-diameter part 24, which serves as the bottom of the main part 2 as a whole, and the second small-diameter part 24 is connected to the second large-diameter part 23.

[0069] Of course, the stop does not have to be a large-diameter circular sleeve. For example, it can be a square sleeve provided on both sides of the circular sleeve along the axis; or a protruding stop mechanism provided on the sleeve; or any structure that can achieve the stopping effect.

[0070] See Figure 2 The second flange 34 is connected to a suspension part 342, which can be used to lift the second flange 34. Exemplarily, the suspension part 342 may include a rope or rod passing through the first flange 33, with a lifting ring 3421 at the end for easy suspension. In one embodiment of this application, the suspension part 342 includes a lifting rod 3422, which includes a large-diameter section 3423 and a small-diameter section 3424. The small-diameter section 3424 can pass through a corresponding through hole in the first flange 33, allowing it to slide relative to the first flange 33. The large-diameter section 3423 cannot pass through the corresponding through hole in the first flange 33, and its lower end is fixedly connected to the second flange 34. The lifting ring 3422 cannot pass through the corresponding through hole, allowing for further control of the closest and furthest distance between the first flange 33 and the second flange 34.

[0071] See Figure 3 , Figures 6 to 8 The first small diameter portion 22 is provided with a lock hole 221, and the first flange 33 is provided with a remotely retractable locking tongue 332. By controlling the locking tongue 332 to extend into the lock hole 221, the first flange 33 and the first small diameter portion 22 can be relatively fixed.

[0072] like Figure 4As shown, the keyhole 221 is located between the first large-diameter portion 21 and the second large-diameter portion 23. For example, the keyhole 221 may be located near the first (upper) trisection point of the first small-diameter portion 22 between the first large-diameter portion 21 and the second large-diameter portion 23. With the latch 332 inserted into the keyhole 221, there is a set distance between the upper surface of the first flange 33 and the lower surface of the first large-diameter portion 21, the second flange 34 abuts against the second large-diameter portion 23, the fixing arm 31 retracts radially inward, and the probe mounting bracket is in a retracted (or closed) state.

[0073] For example, a release mechanism can be installed in the probe mounting bracket to control the extension and retraction of the locking tongue 332. The release mechanism may include a power module, a signal receiving module, and an actuator. The power module supplies power to the signal receiving module and the actuator. The signal receiving module can use wireless transmission modes such as electromagnetic or Bluetooth to receive remote signals. The actuator can be a servo motor, solenoid valve, etc., with its motion mechanism connected to the locking tongue 332. The signal receiving module controls the movement of the servo motor or solenoid valve of the actuator, thereby controlling the linear reciprocating motion of the locking tongue 332 to achieve the release and locking operations between the locking tongue 332 and the lock hole 221. Figure 7 As shown, the bolt 332 is in the released state from the keyhole 221. Figure 7 The central locking bolt 332 is misaligned with the keyhole 221. For example... Figure 8 As shown, the latch 332 and the keyhole 221 are in a locked state.

[0074] With the latch 332 inserted into the lock hole 221, when the suspension part 342 is lifted, the first flange 33 is fixed to the main part 2 through the latch 332 and the lock hole 221. When the suspension part 342 is lifted, the second flange 34, the auxiliary arm 35, the fixed arm 31, the first flange 33, and the main part 2 can be lifted at the same time.

[0075] When the locking tongue 332 is not inserted into the locking hole 221, and the suspension part 342 is lifted, the first flange 33 abuts against the first large diameter part 21. When the suspension part 342 is lifted, the second flange 34, the auxiliary arm 35, the fixed arm 31, the first flange 33, and the main part 2 can be lifted at the same time.

[0076] That is, after the suspension 342 in this application is lifted, its components have two fixed states. The two fixed states can be used for the deployment stage and the retrieval stage of the probe deployment bracket (described later).

[0077] See Figure 2 , Figure 4The main part 2 may also include a telescopic member 32, one end of which is hinged to the fixed arm 31. For example, one end of the telescopic member 32 may be hinged to the upper middle section of the fixed arm 31, and the other end of the telescopic member 32 is hinged to the second flange 34. When the latch 332 is inserted into the lock hole 221, the telescopic member 32 is under pressure. After the latch 332 leaves the lock hole 221, the telescopic member 32 can actively extend to increase the distance between the first flange 33 and the second flange 34, thereby opening the fixed arm 31. Exemplarily, the telescopic member 32 can be a gas spring, a regular spring, a controlled telescopic member, etc. On the one hand, the telescopic member 32 can provide power to open the fixed arm 31; on the other hand, the telescopic member 32 provides support for the fixed arm 31. Compared with only the auxiliary arm 35 providing support, the telescopic member 32 and the auxiliary arm 35 working together to support the fixed arm 31 makes it more stable.

[0078] Further, see Figure 2 The hinge point between the auxiliary arm 35 and the fixed arm 31 is the auxiliary arm-fixed arm hinge point 351. The hinge point between the first flange 33 and the fixed arm 31 is the first flange-fixed arm hinge point 331, and the hinge point between the second flange 34 and the auxiliary arm 35 is the second flange-auxiliary arm hinge point 341. In the axial direction of the main part 2, the second flange-fixed arm hinge point 341 is located between the auxiliary arm-fixed arm hinge point 351 and the first flange-fixed arm hinge point 331, such that when the second flange 34 is lifted, the second flange 34 is close to the first flange 33, and the fixed arm 31 retracts radially inward.

[0079] In a conventional umbrella rib-type opening and closing structure, the first flange connected to the main arm (fixed arm, length cannot be changed) is the highest point, and the second flange connected to the auxiliary arm (length cannot be changed) is the lowest point. Vertically, the hinge point between the second flange and the auxiliary arm is lower than the hinge points of the main arm and the auxiliary arm. When the first and second flanges are far apart, the main arm retracts radially inward, equivalent to closing the umbrella; when the first and second flanges are close together, the main arm expands radially outward, equivalent to opening the umbrella.

[0080] In this application, the hinge point 341 of the second flange auxiliary arm is higher than the hinge point 351 of the auxiliary arm fixed arm. When the first flange 33 and the second flange 34 are far apart, the fixed arm 31 expands radially outward, equivalent to opening an umbrella; when the first flange 33 and the second flange 34 are close together, the fixed arm 31 retracts radially inward, equivalent to closing the umbrella. That is, the opening and closing logic of the sleeve fixing part in this application is different from that of a conventional umbrella frame. In addition, when the suspension part 342 is lifted to retrieve the probe deployment bracket, the first flange 33 abuts against the first large diameter part 21, and the gravity of the main part 2 causes the first flange 33 and the second flange 34 to move closer together, and the fixed arm 31 can retract synchronously, which conforms to the usage logic and makes the equipment operation simpler and more efficient.

[0081] It is understood that by setting the lengths of the fixed arm 31 and the auxiliary arm 35, and the hinge positions of the various components, the relative positions of the aforementioned hinge points can be achieved. In this application, the fixed arm 31, the telescopic member 32, and the auxiliary arm 35 can be assembled into a set of opening and closing structures, and three or more sets of opening and closing structures can be set in the probe deployment bracket. Of course, this application does not limit the specific number of such structures.

[0082] Further, see Figure 1 , Figures 9 to 14 The fixed arm 31 also includes a fixed arm body 311 and a pawl 36 hinged to the fixed arm body 311 for contacting the well wall. The pawl 36 is sequentially provided with a first protrusion 361, a second protrusion 362, and an auxiliary wheel 363. The second protrusion 362 protrudes more than the first protrusion 361, causing the pawl 36 to tilt when it descends and contacts the well wall, thereby causing both the first and second protrusions 361 and 362 to contact the well wall, and moving the auxiliary wheel 363 away from the well wall. The protrusion distance (protrusion degree) of the second protrusion 362 and the auxiliary wheel 363 can be the same.

[0083] On the one hand, the design of the auxiliary wheel 363 allows the fixed arm 31 to retract. When the pawl 36 attempts to disengage from the well wall, the auxiliary wheel 363 receives support from the well wall, providing the torque for the spike to pull out of the well wall. Furthermore, the auxiliary wheel 363 itself will not sink into the well wall; the interaction between the auxiliary wheel 363 and the well wall is rolling friction, making the pulling process easier. On the other hand, the second spike 362 protrudes more than the first spike 361, making it easier for the pawl 36 to tilt when it approaches and descends near the well wall, allowing the spike to more easily embed itself into the well wall. The overall weight of the probe mounting bracket further strengthens the contact between the pawl 36 and the well wall, allowing the auxiliary wheel 363 to move away from the well wall and avoid affecting the fixation of the spike to the well wall.

[0084] Further, see Figure 9 In the arrangement direction of the first thrust 361, the second thrust 362, and the auxiliary wheel 363 ( Figure 9 (Up and down direction) The distance L1 between the tip 3621 of the second spike 362 and the tip 3611 of the first spike 361 is equal to the distance L2 between the tip 3621 of the second spike 362 and the center 3631 of the auxiliary wheel 363. The rotation center 364 of the pawl 36, which is hinged to the fixed arm body 311, is located between the tip 3611 of the first spike 361 and the tip 3621 of the second spike 362. That is, the rotation center 364 is biased towards the first spike 361, which facilitates the deflection of the pawl 36.

[0085] For example, the working process of the probe deployment bracket is as follows.

[0086] During the preparation phase, the suspension part 342 is lifted, compressing the distance between the first flange 33 and the second flange 34. The telescopic component 32 is compressed under force, and the locking tongue 332 of the first flange 33 is aligned with the locking hole 221 on the main part 2. The locking is remotely locked, and the locking tongue 332 is inserted into the locking hole 221, so that the first flange 33 and the main part 2 are in a locked state, and the second flange 34 abuts against the second large diameter part 23.

[0087] For the deployment phase, see [link / reference] Figure 1 The suspension unit 342 is hoisted, suspending the probe placement bracket at the corresponding position in the well 1. Remote unlocking is performed, and the locking tongue 332 disengages from the locking hole 221, releasing the locking state between the first flange 33 and the main unit 2. The telescopic component 32 extends, increasing the distance between the first flange 33 and the second flange 34 until the main unit 2 descends. The first flange 33 abuts against the first large-diameter section 21 of the main unit 2, and the fixing arm 31 expands radially outward, releasing the suspension unit 342. The pawl 36 abuts against and is fixed to the well wall. The supporting force of the well wall balances the weight of the probe placement bracket, thus fixing the position of the probe placement bracket in the well 1. Then, the probe 4 is hoisted from the central hole of the main unit 2 into the monitoring area 5 using the probe hoisting rope, completing the probe placement.

[0088] For the recycling phase, see Figure 12 Pull the probe 4 out of the well 1. Then lift the suspension part 342, and the auxiliary arm 35 drives the fixed arm 31 to retract. The first flange 33 abuts against the first large diameter part 21, and the second flange 34 approaches the first flange 33. The telescopic component 32 is compressed under force, releasing the fixed relationship between the probe mounting bracket and the well wall, and pulling the probe mounting bracket out of the well 1.

[0089] It is understandable that during the deployment phase, after the probe deployment bracket is suspended in the well 1, the pawl 36 of the probe deployment bracket can be automatically fixed to the well wall by remotely controlling the locking tongue 332 to leave the locking hole 221; during the retrieval phase, when the probe deployment bracket is lifted, the pawl 36 automatically disengages from the well wall and is fixed. The control process is simple and the installation and retrieval are convenient.

[0090] Example 2

[0091] The probe deployment bracket provided in Embodiment 2 of this application may include a shaft, a shaft fixing part, a first flange 33, a second flange 34, and an auxiliary arm 35.

[0092] The probe 4 can be connected to the shaft, which includes a first stop and a second stop spaced apart axially thereon.

[0093] The shaft fixing part includes a plurality of fixing arms 31 that can be extended radially outward and retracted radially inward. When the plurality of fixing arms 31 are extended, they abut against the well wall of the well 1 to fix the position of the shaft in the well 1.

[0094] The second flange 34 is located below the first flange 33 and is slidably disposed on the shaft portion, while the first flange 33 is slidably disposed on the shaft portion. In the axial direction, the first flange 33 and the second flange 34 are located between the first stop portion and the second stop portion, thereby limiting the maximum distance between the first flange 33 and the second flange 34. One end of the fixed arm 31 is hinged to the first flange 33.

[0095] One end of the auxiliary arm 35 is hinged to the other end of the fixed arm 31, and the other end of the auxiliary arm 35 is hinged to the second flange 34. The second flange 34 is connected to a suspension part 342. When the suspension part 342 is lifted, the second flange 34 approaches the first flange 33, and the distance between the first flange 33 and the second flange 34 decreases, causing the fixed arm 31 to retract radially inward.

[0096] The hinge point between the auxiliary arm 35 and the fixed arm 31 is the auxiliary arm fixed arm hinge point 351. The hinge point between the first flange 33 and the fixed arm 31 is the first flange fixed arm hinge point 331. The hinge point between the second flange 34 and the auxiliary arm 35 is the second flange auxiliary arm hinge point 341. In the axial direction, the second flange auxiliary arm hinge point 341 is located between the auxiliary arm fixed arm hinge point 351 and the first flange fixed arm hinge point 331, so that when the second flange 34 and the first flange 33 are close together, the fixed arm 31 retracts radially inward.

[0097] Furthermore, the shaft fixing part also includes a telescopic rod, one end of which is hinged to the fixing arm 31, and the other end of which is hinged to the second flange 34. The first flange 33 is provided with a remotely telescopic locking tongue 332, and the shaft is provided with a locking hole 221. In the axial direction, the locking hole 221 is located between the first stop and the second stop. The locking tongue 332 extends into the locking hole 221 to achieve relative fixation between the first flange 33 and the shaft. At this time, the first flange 33 is away from the first stop by a certain distance, the second flange 34 abuts against the second stop, and the fixing arm 31 retracts radially inward.

[0098] Example 3

[0099] Compared with Examples 1 and 2, Example 3 differs in that the main fixing part 3 or the shaft fixing part includes a fixing arm 31, a telescopic arm, a first flange, and a second flange.

[0100] The first and second flanges are fixed to the main part 2 or the shaft, eliminating the need for the aforementioned locking tongue and other mechanisms. One end of the telescopic arm is hinged to the fixed arm 31, allowing the telescopic arm to extend and retract in a controlled manner. The fixed arm 31 is hinged to the first flange, and the other end of the telescopic arm is hinged to the second flange. By actively controlling the extension and retraction of the telescopic arm, the fixed arm 31 can be opened or retracted. For example, the telescopic arm can be an electrically controlled robotic arm, etc. The telescopic arm can controllably and actively change its length, thereby controlling the tightness between the fixed arm 31 and the well wall, facilitating precise control of the tightness in actual engineering scenarios and preventing damage to the fixed arm 31 or insufficient tightness between the fixed arm 31 and the well wall.

[0101] The well water quality monitoring system provided in this application is used to monitor the water quality of monitoring area 5 in well 1. The well water quality monitoring system may include the aforementioned probe mounting bracket and monitoring equipment. The monitoring equipment may include a probe 4, which may be connected to the main body 2 or the shaft.

[0102] In one embodiment of this application, the monitoring device may include a probe suspension rope for suspending the probe 4, which can pass through the main part 2 into the monitoring area 5. The probe 4 or the probe suspension rope abuts against the inner wall of the main part 2 to limit the swing of the probe 4. The probe 4 may be partially located in the main part 2, and the diameter of the structure of the probe 4 located in the main part 2 is similar to the inner diameter of the main part 2 to avoid the probe 4 swinging.

[0103] In another embodiment of this application, the probe 4 is fixedly connected to the shaft. The probe 4 can be directly connected to the shaft or connected to the shaft via a flexible member. The flexible member can be a rope, chain, etc., allowing the probe 4 to swing slightly within the monitoring area 5, thereby reducing the risk of collision and interference with debris in the well.

[0104] Of course, the shaft can also be a hollow shaft. The probe 4 passes through the hollow shaft into the monitoring area 5, and the probe 4 or the probe suspension rope abuts against the inner wall of the hollow shaft to limit the swing of the probe 4.

[0105] Probe 4 can be electrically connected to the explosion-proof power supply box at the wellhead. The explosion-proof power supply box supplies power to probe 4, and data exchange can be achieved between probe 4 and the explosion-proof power supply box. The probe hoisting rope is a comprehensive rope that integrates functions such as lifting the probe, providing power, and transmitting data.

[0106] The above description is the preferred embodiment of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
