Description

Technical Field

[0001] This utility model relates to the field of groundwater monitoring technology, and in particular to a sensor mounting bracket for groundwater monitoring. Background Technology

[0002] Groundwater monitoring plays a vital role in water resource assessment, environmental protection, and geological safety management. By continuously collecting data on changes in groundwater level, temperature, and quality, it can provide crucial data for regional recharge analysis, pollution source tracing, and underground structure stability assessment. Monitoring equipment typically needs to be placed at the wellhead or inside the well wall for extended periods and maintain stable contact with the water body to ensure data continuity and reliability. To ensure that the sensors maintain a suitable spatial position and orientation within the well, it is often necessary to use structurally stable sensor mounting brackets to achieve sensor fixation, support, and positioning functions.

[0003] Existing sensor mounting brackets generally rely on additional bolts, nuts, and other fasteners for fixation during use, which is time-consuming. Moreover, most of these structures only have single-point or limited contact surface fixation methods, making it difficult to form a stable multi-point clamping effect in a short time. This causes the sensor to easily shift its position under stress or vibration. In addition, existing brackets are generally installed by directly fitting them to the inner wall of the wellhead, lacking an initial fixation mechanism that can actively push outward against the well wall and form compressive force. This makes it difficult for the bracket to quickly maintain a stable posture in the early stages of installation, requiring subsequent cumbersome tightening operations for reinforcement.

[0004] Therefore, this utility model proposes a sensor mounting bracket for groundwater monitoring. Utility Model Content

[0005] Therefore, in order to overcome the problems that existing sensor mounting brackets mostly rely on bolts and nuts for fixing, which is time-consuming to install and usually only have a single point or a small number of contact surfaces, making it difficult to quickly form a stable multi-point clamping, which makes the sensor easy to shift when subjected to force or vibration. At the same time, these brackets mostly directly fit against the inner wall of the wellhead and lack an active compressive force structure to push the well wall outward, making it difficult to maintain a stable posture in the early stage of installation, and can only rely on subsequent cumbersome fastening steps for reinforcement.

[0006] The technical solution of this utility model is as follows: a sensor mounting bracket for groundwater monitoring, comprising a placement plate, a connecting rod, and a fixing ring; a fastening plate is fixedly connected to the bottom of the placement plate, a connecting block is fixedly connected to the end of the fastening plate away from the placement plate, the connecting rod is fixedly connected to the outside of the connecting block, a positioning ring is fixedly connected to the end of the connecting rod away from the connecting block, the connecting rod is symmetrically installed on the outer wall of the positioning ring, and the fixing ring is fixedly connected to the top of the positioning ring.

[0007] Preferably, the fastening plate and the connecting block are an integrated structure, and the placement plate, fastening plate and connecting block are symmetrically distributed on both sides of the positioning ring.

[0008] Preferably, the placement plate has fixing holes symmetrically distributed on both sides of the placement plate, and the fastening plate has a drive screw threadedly connected to its interior. The drive screw is located near the center of the fastening plate, and the fastening plate has a limit shaft slidably connected to its interior. The limit shaft is symmetrically installed near the drive screw.

[0009] Preferably, a balance spring is sleeved on the outer side of the limiting shaft, one end of the balance spring is fixedly connected to the inner side of the fastening plate, and the other end of the balance spring is fixedly connected to a sliding push plate. The driving screw is rotatably connected to the side of the sliding push plate close to the balance spring, the limiting shaft is fixedly connected to the side of the sliding push plate close to the balance spring, and a fastening pad is fixedly connected to the side of the sliding push plate away from the balance spring.

[0010] Preferably, a reinforcing rod is fixedly connected to the outer wall of the connecting rod. The reinforcing rod is symmetrically installed at a position away from the positioning ring, and the end of the reinforcing rod away from the connecting rod is fixedly connected to the outer side of the connecting block.

[0011] Preferably, the fixed ring is internally threaded with a limiting screw, which is symmetrically installed near the outer wall of the fixed ring. A guide disc is fixedly connected to the inner wall of the fixed ring, and a fixing block is slidably connected to the top of the guide disc. The fixing blocks are evenly distributed inside the fixed ring, and a sliding shaft is fixedly connected to the bottom of the fixing blocks. The sliding shaft is slidably connected inside the guide disc.

[0012] Preferably, a guide turntable is rotatably connected to the inner side wall of the fixed ring, and a lever is fixedly connected to the outer side wall of the guide turntable. The lever is slidably connected inside the fixed ring. A guide groove is provided inside the guide turntable. The guide grooves are evenly distributed at a position close to the center of the guide turntable, and the sliding shaft is slidably connected inside the guide groove.

[0013] The beneficial effects of this utility model are: When the device needs to be fixed, the two sets of drive screws are rotated simultaneously to push the sliding push plate towards the well wall. The balance spring is stretched and released synchronously to ensure that the two sides of the sliding push plate remain synchronized. During this process, the limit shaft provides limit guidance to maintain the overall motion stability. Finally, the fastening pad fits against the well wall, forming an outward compressive force to support the well wall, thereby achieving the initial stabilization of the device. There is no need to quickly maintain a stable posture in the early stage of installation, which simplifies the complexity of subsequent reinforcement and fixing operations. When it is necessary to enhance the fixing effect of the device, after inserting the bolt into the fixing hole, adjust the position appropriately along the fixing hole and further push it into the wellhead area. At this time, the placement plate is firmly fixed at the wellhead, so that the device obtains a more reliable fixing state. When installing a groundwater monitoring sensor, after placing the sensor inside the fixing ring, turn the lever to rotate the guide turntable. The sliding shaft moves towards the center along the guide groove and the guide disc, and the fixing blocks retract synchronously, forming a three-point clamping of the sensor. Then, rotate the limiting screw to press it against the guide turntable. The rotation of the guide turntable is restricted by friction locking, thereby locking the position of the fixing blocks and completing the stable fixation of the sensor. A stable multi-point clamping effect can be formed in a short time, preventing the sensor from shifting its position under force. Attached Figure Description

[0020] Please see Figures 1-7 This utility model provides a technical solution: a sensor mounting bracket for groundwater monitoring, including a placement plate 1, a connecting rod 4, and a fixing ring 6; a fastening plate 2 is fixedly connected to the bottom of the placement plate 1, a connecting block 3 is fixedly connected to the end of the fastening plate 2 away from the placement plate 1, the connecting rod 4 is fixedly connected to the outside of the connecting block 3, a positioning ring 5 is fixedly connected to the end of the connecting rod 4 away from the connecting block 3, the connecting rod 4 is symmetrically installed on the outer wall of the positioning ring 5, and the fixing ring 6 is fixedly connected to the top of the positioning ring 5.

[0021] The fastening plate 2 and the connecting block 3 are an integrated structure. The placement plate 1, fastening plate 2 and connecting block 3 are symmetrically distributed on both sides of the positioning ring 5. The symmetrical distribution of the placement plate 1, fastening plate 2 and connecting block 3 on the positioning ring 5 makes the entire device more evenly stressed at the wellhead and inside the well, which can improve the overall stability of the positioning ring 5.

[0022] The placement plate 1 has a fixing hole 101 inside, which is symmetrically distributed on both sides of the placement plate 1. The fastening plate 2 has a drive screw 201 threaded inside, which is located near the center of the fastening plate 2. The fastening plate 2 has a limit shaft 202 slidably connected inside, which is symmetrically installed near the drive screw 201. The limit shaft 202 keeps the movement of both sides consistent when pushing the sliding structure, reduces offset and jamming, and improves the fixed stability and operational reliability of the device at the wellhead.

[0023] A balance spring 203 is sleeved on the outer side of the limiting shaft 202. One end of the balance spring 203 is fixedly connected to the inner side of the fastening plate 2, and the other end of the balance spring 203 is fixedly connected to the sliding push plate 204. The drive screw 201 is rotatably connected to the side of the sliding push plate 204 near the balance spring 203. The limiting shaft 202 is fixedly connected to the side of the sliding push plate 204 near the balance spring 203. A fastening pad 205 is fixedly connected to the side of the sliding push plate 204 away from the balance spring 203. During the force-driven movement, the sliding push plate 204 can move outward synchronously under the action of the balance spring 203. The limiting shaft 202 provides stable guidance. Finally, the fastening pad 205 adheres to the well wall to form a uniform external support force, thereby improving the stability and force balance of the sliding structure.

[0024] A reinforcing rod 401 is fixedly connected to the outer wall of the connecting rod 4. The reinforcing rod 401 is symmetrically installed at a position away from the positioning ring 5. The end of the reinforcing rod 401 away from the connecting rod 4 is fixedly connected to the outer side of the connecting block 3. The reinforcing rod 401 provides the connecting rod 4 with additional lateral support during use, improves its overall stability, reduces the swing and deformation of the connecting rod 4 after being subjected to force, and thus enhances the stability of the positioning ring 5.

[0025] The fixed ring 6 has a limit screw 601 connected to its internal thread. The limit screw 601 is symmetrically installed near the outer wall of the fixed ring 6. A guide disk 602 is fixedly connected to the inner wall of the fixed ring 6. A fixed clamping block 603 is slidably connected to the top of the guide disk 602. The fixed clamping blocks 603 are evenly distributed inside the fixed ring 6. A sliding shaft 604 is fixedly connected to the bottom of the fixed clamping block 603. The sliding shaft 604 is slidably connected inside the guide disk 602, so that the clamping structure synchronously closes or opens along a predetermined trajectory under the constraint of the guide disk 602, forming a stable and uniform multi-point clamping force, which can effectively improve the positioning reliability of the sensor inside the fixed ring 6.

[0026] A guide turntable 605 is rotatably connected to the inner wall of the fixed ring 6, and a lever 606 is fixedly connected to the outer wall of the guide turntable 605. The lever 606 is slidably connected inside the fixed ring 6. A guide groove 607 is provided inside the guide turntable 605. The guide grooves 607 are evenly distributed at a position close to the center of the guide turntable 605. A sliding shaft 604 is slidably connected inside the guide groove 607. When the lever 606 drives the guide turntable 605 to rotate, the sliding shaft 604 moves synchronously radially along the guide groove 607, thereby realizing the coordinated closing or opening of the fixed clamping block 603 and improving the clamping reliability during sensor installation.

[0027] Working principle: See Figures 1-2 As shown, when the device is ready for use, first, the device is moved to the working area. Then, the placement plate 1 is placed steadily at the wellhead of the groundwater well, and the fastening plate 2 and the connecting block 3 are located in the well below the wellhead to complete the initial placement of the device. See Figure 3 As shown, when the device needs to be fixed, firstly, both sets of drive screws 201 are simultaneously held and external force is applied to rotate them, causing them to push the sliding push plate 204 to move towards the well wall. As the sliding push plate 204 is driven to move outward, the balance spring 203 is stretched and released synchronously to ensure that both sides of the sliding push plate 204 remain synchronized. During this process, the limiting shaft 202 provides guidance for the sliding push plate 204 and limits the lateral displacement of the balance spring 203, maintaining the overall motion stability. Finally, the fastening pad 205 on the sliding push plate 204 fits against the well wall, forming an outward compressive force to support the well wall, thereby achieving the initial stabilization of the device. See Figure 3 As shown, when it is necessary to enhance the fixing effect of the device, firstly, align the external bolts and insert them into the fixing holes 101. After adjusting the position appropriately along the fixing holes 101, further push the external bolts into the wellhead area. At this time, the placement plate 1 is pressed into the wellhead position, so that the device obtains a more secure fixing state at the wellhead. See Figures 5-7 As shown, when an external groundwater monitoring sensor needs to be installed, firstly, the sensor is placed inside the fixing ring 6. Then, an external force is applied to turn the lever 606, causing it to rotate the guide turntable 605. The sliding shaft 604 moves along the guide groove 607, and the guide disc 602 further guides the sliding shaft 604 to move towards the center of the fixing ring 6. At this time, the fixing block 603 retracts synchronously with the sliding shaft 604. The anti-slip soft pad on the inner side of the fixing block 603 forms a three-point clamp for the sensor. Then, the limiting screw 601 is grasped and an external force is applied to rotate it, so that it passes through the guide disc 602 and presses against the upper surface of the guide turntable 605. The further rotation of the guide turntable 605 is restricted by friction locking, thereby locking the position of the fixing block 603 and thus completing the stable fixation of the sensor. See Figure 4 As shown, during normal use of the device, firstly, the connecting block 3 and the connecting rod 4 provide stable support for the positioning ring 5, and the reinforcing rod 401 further enhances the stability of the connecting rod 4. After being fixed, the groundwater monitoring sensor extends downward along the well under the guidance of the positioning ring 5, so that the sensor can reliably enter the groundwater area and maintain a fixed posture, thereby completing the entire monitoring operation process.
