Description

Technical Field

[0001] The present application relates to the technical field of support devices, and in particular to a mounting bracket and a monitoring system. Background Art

[0002] At present, when monitoring and measuring water quality inside a pipe well, technicians are often required to enter the pipe well to install casing and monitoring equipment. However, there are often toxic and harmful gases inside the pipe well, and working inside the pipe well is a highly dangerous job. At the same time, in the case of high-velocity water flow underground, operators may not be able to go down to the well to work, and they need to coordinate with relevant units to carry out operations such as interception and pump stop, which will bring great costs. Therefore, there is an urgent need for a reliable installation bracket that does not require going down to the well, so that technicians can install and fix the casing without going down to the well. When fixing the casing in the pipe well, it is also necessary to consider factors such as the impact of underground water flow, the aging of the well wall, which may cause the fasteners to loosen and disengage, and the few fixed connection points may cause the casing to swing.

[0003] CN209102696U discloses a PH probe fixed protective sleeve, which is matched with a PH probe and is used in the measurement of the PH value of the liquid in the pool. The structure of the PH probe fixed protective sleeve is set as follows: the stainless steel protective sleeve is installed on the pool wall through multiple fixed brackets on the outer tube wall, the top end is threadedly assembled with the locking joint, and the bottom outer tube wall is provided with an external thread section. The bottom end of the probe protective sleeve is open and the surrounding wall is densely covered with small holes. The top end is provided with an internal thread section, which is threadedly matched with the external thread section at the bottom of the stainless steel protective sleeve and assembled on the stainless steel protective sleeve. The PH probe is placed in the probe protective sleeve and threadedly assembled on the top of the probe protective sleeve.

[0004] The pH probe fixing protection sleeve disclosed in the above utility model uses multiple fixing brackets to install the sleeve on the pool wall. This fixing method still requires technicians to go down the well to install the fixing bracket at the bottom of the sleeve. At the same time, this installation method may cause the fixing parts to fall off and loosen after long-term use. Utility Model Content

[0075] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0076] The embodiment of the present application provides a mounting bracket for installing a pipe well equipment in cooperation with a casing, such as Figure 1 and Figure 2 As shown, the mounting bracket 100 may include a support member 110 , one or more telescopic rods 120 , and one or more clamping blocks 130 .

[0077] First embodiment

[0078] Specifically, the support member 110 may be a rod-shaped structure, which may be arranged along the depth direction of the pipe well. When in use, the support member 110 may abut against the wall of the pipe well, that is, it may be arranged parallel to the wall of the pipe well. The length of the telescopic rod 120 may be adjusted, and one end of the telescopic rod 120 may be rotatably connected to the support member 110. The other end of the telescopic rod 120 may be directly or indirectly rotatably connected to the block 130, and the block 130 may abut against the wall of the pipe well when in use and / or the block 130 may be sleeved on the casing 200 (see Figure 4 ).

[0079] Further, the telescopic rod 120 may include a first telescopic rod 121 and a second telescopic rod 122, and the first telescopic rod 121 and the second telescopic rod 122 may be sleeved. Exemplarily, the second telescopic rod 122 may at least partially form a tubular structure (hollow structure), and the outer diameter of the first telescopic rod 121 may be less than or equal to the inner diameter of the tubular structure of the second telescopic rod 122, so that the second telescopic rod 122 may be sleeved on the first telescopic rod 121.

[0080] The first telescopic rod 121 may be formed with one or more first limiting holes 1211, and the second telescopic rod 122 may be formed with one or more second limiting holes 1221. At least some of the first limiting holes 1211 may overlap with at least some of the second limiting holes 1221. The overlapping first limiting holes 1211 and second limiting holes 1221 may be inserted with limiting members such as locking screws and latches to limit the relative movement of the first telescopic rod 121 and the second telescopic rod 122 in the length direction. The first telescopic rod 121 and the second telescopic rod 122 are relatively fixed, that is, the length of the telescopic rod 120 can be fixed.

[0081] Optionally, the first telescopic rod 121 may form one or more elastic limiting protrusions, and the second telescopic rod 122 may form one or more limiting holes. At least part of the one or more elastic limiting protrusions may be inserted into at least part of the one or more limiting holes to limit the relative movement of the first telescopic rod 121 and the second telescopic rod 122 in the length direction.

[0082] Optionally, the support member 110 may form a telescopic rod connection portion 111, the first telescopic rod 121 may form a support member connection portion 1212, and the telescopic rod connection portion 111 may be rotatably connected to the support member connection portion 1212. It is understood that the telescopic rod connection portion 111 and the support member connection portion 1212 may be separate rotating connectors, or may be a rotating connection structure formed by processing (e.g., punching) on ​​the support member 110 and the first telescopic rod 121.

[0083] Optionally, the telescopic rod 120 may also use an automatic telescopic device such as an electric cylinder. For example, a pressure sensor may be provided at the connection between the support member 110 and the telescopic rod 120 to adjust the telescopic length of the electric cylinder in real time according to the pressure change, so that the mounting bracket can be suitable for the situation where the well wall against which the support member abuts is uneven or the diameter of the pipe well changes with the well depth.

[0084] Preferably, when the mounting bracket 100 is installed in place, its total length in the horizontal direction can be greater than or equal to the diameter of the pipe well to be installed, especially slightly greater than the diameter of the pipe well, so that the mounting bracket 100 can form a firm support for the casing, etc.

[0085] Preferably, one side of the support member 110 that is used to abut against the wall of the pipe shaft can be provided with an anti-slip structure 112 such as a silicone pad or a convex-concave structure, a tooth structure, etc. to enhance the friction between the support member 110 and the wall of the pipe shaft. The silicone pad can be soft silicone.

[0086] The block 130 may be formed with a casing channel 131, which may be used to accommodate or pass a casing (installation pipe). The extension direction (axial direction) of the casing channel 131 may be the same as the length extension direction of the support member 110, that is, the same as the depth direction of the pipe well.

[0087] Optionally, the clamping block 130 may be made of a soft material such as a rubber ring; or a hard clamping structure such as metal. The clamping block 130 may be tightly sleeved to the sleeve 200; or there may be a gap between the clamping block 130 and the sleeve 200, so that the clamping block 130 is pressed against the sleeve 200 when the mounting bracket is pressed.

[0088] Preferably, when the mounting bracket 100 is used in conjunction with a casing, a cable or the like may be provided above the casing to hoist and connect the casing to a well wall or a wellhead or the like.

[0089] Optionally, when the mounting bracket cooperates with the casing, the casing can be connected to the mounting bracket (block 130) and then placed in the pipe well. Alternatively, the casing 200 can be placed in the pipe well first, and then the blocks can be inserted sequentially from the upper part of the casing.

[0090] like Figure 3 and Figure 4 As shown, optionally, the support member 110 may also be a telescopic rod with adjustable length. The mounting bracket can be adapted to pipe wells of different depths by adjusting the length of the support member 110. The support member 110 may be connected to one or more telescopic rods 120, and each telescopic rod 120 may be connected to a block 130. The specific number of telescopic rods 120 connected to the support member 110 is not limited and can be flexibly adjusted according to actual needs such as the depth of the pipe well.

[0091] Preferably, the telescopic rod 120 can be connected to the block 130 via a rotating connection portion 140. The rotating connection portion 140 can be fixedly connected to the block 130. The rotating connection portion 140 can be movably connected to the telescopic rod 120, especially rotatably connected to the end of the second telescopic rod 122 that is not connected to the first telescopic rod 121. The rotating connection portion 140 can be formed with a rotation limit portion 141, and the rotation limit portion 141 can be at least partially arranged at the bottom of the telescopic rod 120 (the side of the second telescopic rod 122 facing the bottom of the pipe well). Figure 5 As shown, the rotation limiter 141 can limit the relative rotation of the block 130 and the second telescopic rod 122, that is, after the block 130 is sleeved on the sleeve, the telescopic rod 120 cannot rotate to the lower side relative to the block 130. In other words, one end of the connecting support member 110 of the telescopic rod 120 is not lower than one end of the connecting block 130 of the telescopic rod 120. It can be understood that the rotation connection part 140 can be integrally formed with the block 130, that is, the rotation limiter can be extended from the block.

[0092] Preferably, the mounting bracket 100 may further include a traction rope 150 (see Figure 4 ). One end of the traction rope 150 can be connected to the upper end of the support member 110 (especially the support member closest to the well mouth or the support member shared by multiple mounting brackets). It can be understood that the other end of the traction rope 150 can be left outside the well. The traction rope 150 can also be connected to the well wall, well mouth, etc. of the well as a safety traction rope to prevent the mounting bracket from accidentally falling off and falling into the well due to other factors. On the other hand, when disassembling the mounting bracket 100, the traction rope 150 can be pulled upward to change the angle between the support member 110 and the telescopic rod 120, so that the mounting bracket (especially its support member 110) can be separated from the wall of the well to release the fastening state of the mounting bracket. The traction rope 150 can be a steel wire rope.

[0093] Preferably, the multiple support members 110 of the mounting bracket can be flexibly connected to each other to adapt to pipe wells with varying diameters. Exemplarily, rubber rods, hard springs, etc. can be provided between the multiple support members 110. It is understandable that the rubber rods, hard springs, etc. can form a certain degree of deformation, so that a certain bending angle can be formed between the support members 110, but the downward pressing force applied to the support members can still be transmitted. Mechanisms such as angle-limited rotating shafts can also be provided between the multiple support members 110 to achieve the above-mentioned purpose of adapting to pipe wells with varying diameters.

[0094] The following briefly describes an exemplary operation of the first embodiment of the present application.

[0095] First, measure the inner wall diameter of the working pipe well. Adjust the length of the telescopic rod 120 so that the horizontal length of the mounting bracket 100 is slightly larger than the inner wall diameter of the pipe well. Measure the depth of the pipe well (the well depth may not include the irregular area near the wellhead) and the length of the casing 200 to be supported, and then determine the number of support members 110 included in the mounting bracket. Exemplarily, a deeper pipe well can be provided with three or more support members 110 and telescopic rods 120 to form three or more support points including upper, middle and lower. A shallower pipe well can only be provided with two support members 110 to form upper and lower support points. Afterwards, multiple mounting brackets 100 are connected in sequence, and multiple card blocks 130 are respectively sleeved on the outside of the casing 200. The support member 110 can be connected to the traction rope 150 for hoisting operations, and the mounting bracket is placed in a suitable position of the casing 200. In the process of placing the mounting bracket, the support member 110 can be relatively pulled upward to shorten the horizontal length of the mounting bracket 100 to avoid the mounting bracket 100 from getting stuck when it is not installed in place. After the mounting bracket reaches a suitable position, the support member can be loosened to make the telescopic rod perpendicular to (including substantially perpendicular to) the well wall or casing. After the mounting bracket is fully installed, the traction rope 150 can be connected to the well wall or wellhead. When disassembling the mounting bracket or removing the casing 200, the traction rope 150 only needs to be pulled upward so that the support member 110 is not close to the well wall, and the support of the mounting bracket to the casing can be released.

[0096] Second embodiment

[0097] Refer to the following Figures 6 to 11 The second embodiment of the present application will be described. Components having the same or similar structures or functions as those in the first embodiment are denoted by the same reference numerals, and detailed descriptions of these components will be omitted.

[0098] like Figure 6 , Figure 7 , Fig. 9 and Fig.10 As shown, the support member 110 can be a block structure in addition to the rod-shaped structure mentioned above. The length of the telescopic rod 120 can be 50 to 100 mm greater than the diameter of the pipe well. Figure 6 As shown, one end of the telescopic rod 120 connected to the support member 110 can be rotated to an end lower than the connecting block 130 of the telescopic rod 120. The traction rope 150 can be used to connect the support member 110 to the wellhead or well wall, such as Figure 6 and Figure 7 As shown, the upper end of the traction rope 150 can form a hoisting structure 151. For example, the hoisting structure 151 can be a structure such as a hook.

[0099] The telescopic rod 120 can be fixedly connected to the rotating connection part 140, and the clamping block 130 can be rotatably connected to the rotating connection part 140. Exemplarily, the rotating connection part 140 can have a tubular structure or a columnar structure with a diameter less than or equal to the inner diameter of the second telescopic rod 122, so that the rotating connection part 140 can be plug-connected with the second telescopic rod 122. The rotating connection part 140 and the clamping block 130 can form corresponding pin holes to rotatably connect the two through the pin. The rotating connection part 140 may not be provided with a rotation limiting part 141, that is, the mounting bracket of this embodiment does not need to limit the rotation angle of the telescopic rod 120 relative to the clamping block 130 through the rotating connection part 140 when working.

[0100] It can be understood that when installing the mounting bracket provided in the second embodiment, one end of the traction rope 150 can be connected to the support member 110, and the other end of the traction rope 150 can be connected to the wellhead or well wall of the pipe well. One end of the connecting support member 110 of the telescopic rod 120 is made lower than one end of the connecting block 130 of the telescopic rod 120. When the telescopic rod 120 needs to be compressed, the traction rope 150 can be pulled upward to clamp the mounting bracket 100 into the pipe well, thereby completing the installation of the mounting bracket.

[0101] like Figure 6 , Figure 7 and Figure 8 As shown, the monitoring system provided by the second embodiment may further include a fixing device 300. The fixing device 300 is used to fix the casing 200 to the wellhead or the well wall.

[0102] Specifically, Fig.11 and Fig.12 As shown, the fixing device 300 may include a first fixing member 310 and a second fixing member 320. The first fixing member 310 is used to connect the wellhead or the well wall. The first fixing member 310 may include a slot 311, a bracket plate 312 and a bolt 313. A plurality of bolts 313 may be used to connect the bracket plate 3121 to the wellhead or the well wall of the pipe well. For example, four expansion bolts are provided in this embodiment. The bracket plate 312 may be provided with a slot 311. The second fixing member 320 may include a clamping portion 321 and a mounting portion 322. The clamping portion 321 may be engaged with the slot 311. It can be understood that after the clamping portion 321 is engaged with the slot 311, bolts or the like may be used to relatively fix the two. The mounting portion 322 may be used to set the casing 200. For example, the mounting portion 322 may be a structure such as a clamp.

[0103] It can be understood that when the fixing device 300 is used to connect the casing 200 to the pipe well, the first fixing member 310 can be connected to the wellhead or the wall of the pipe well, and the second fixing member 320 can be connected to the casing (the mounting portion 322 is connected to the casing 200). Then, the clamping portion 321 of the second fixing member 320 is inserted into the clamping groove 311 of the first fixing member 310, and the clamping portion 321 and the clamping groove 311 are fixed relative to each other using fixing members such as bolts.

[0104] Preferably, Fig.11 and Fig.12 As shown, the support plate 312 can form a certain curvature or bending angle to adapt to the curved surface of the well wall or wellhead of the pipe well.

[0105] The embodiment of the present application also provides a monitoring system, such as Figure 4 As shown, the monitoring system may include the above-mentioned mounting bracket 100 and the water quality monitoring device. Optionally, multiple mounting brackets 100 may be connected in sequence, and in particular, their support members 110 may be connected in sequence. It is understood that multiple interconnected support members 110 are convenient for flexible adjustment according to the specific pipe well depth. Multiple blocks 130 may be sleeved on the casing 200.

[0106] Preferably, the water quality monitoring device may include a spectral sensor. Preferably, the spectral sensor may include a detector, and the detector may use quantum dots (such as chromium selenide quantum dots) as semiconductor nanocrystals to absorb light of a predetermined wavelength.

[0107] It can be understood that when the angle between the telescopic rod 120 and the sleeve 200 is 90 degrees (including approximately 90 degrees), the horizontal support length of the mounting bracket 100 is the largest. In actual application, when the mounting bracket 100 is in the installed state, the maximum angle (acute angle) between the telescopic rod 120 and the sleeve 200 can be slightly less than 90 degrees.

[0108] Preferably, the distances between adjacent telescopic rods 120 in a plurality of mounting brackets 100 may be equal.

[0109] Preferably, the mounting bracket may be mounted to the downstream side of the pipe well in the water flow direction.

[0110] The following briefly describes some of the beneficial effects of the above-mentioned embodiments of the present application.

[0111] The mounting bracket and monitoring system provided by the embodiment of the present application adopt a structure in which the support member and the telescopic rod can rotate relative to each other, and can form a strong and reliable support for the middle and lower parts of the mounting pipe without the need for technicians to go down to work. This technical solution can solve the technical problem of providing a stable support for the middle and lower parts of the mounting pipe (casing) without the technicians going down to work. The use of this technical solution can reduce the operational risks of technicians, reduce the difficulty of casing fixing operations, and improve the stability of installation.

[0112] It is understood that in the present application, when the number of parts or components is not particularly limited, the number may be one or more, and the multiple here means two or more. For the case where the number of parts or components shown in the drawings and / or described in the specification is a specific number such as two, three, four, etc., the specific number is usually exemplary and not restrictive, and it can be understood as multiple, that is, two or more, but this does not mean that the present application excludes the case of one.

[0113] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present application. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present application without departing from the scope of the present application.
