Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, specifically to a wellhead maintainable flow meter support device. Background Technology

[0002] Hydrological monitoring refers to the long-term or real-time collection, analysis, and early warning of key parameters such as water quantity, water level, water quality, flow velocity, flow direction, and water temperature of water bodies in nature (such as rivers, lakes, reservoirs, groundwater, and oceans) through scientific methods, instruments, and data systems. Its core objective is to understand the laws governing the hydrological cycle, providing data support for water resource management, flood control and drought relief, ecological protection, and engineering construction. It is a crucial foundation for ensuring water security and sustainable ecological development.

[0003] Current current meter supports generally adopt a well-wall fixed design, with the support directly anchored to the middle of the well wall by bolts. When the current meter requires regular maintenance after installation (such as cleaning tangled debris or calibrating the sensor), operators must enter the confined space to work. This not only requires the preparation of complex confined space operation plans and special operation approvals, but also poses significant safety hazards. This maintenance method is not only costly (requiring specialized protective equipment and multiple monitoring personnel), but its frequency is also limited by approval processes and weather conditions, making it difficult to meet the regular maintenance needs of hydrological monitoring equipment and becoming a bottleneck restricting the effectiveness and operational safety of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a wellhead maintainable flow meter bracket device, which detachably connects the mounting frame and the bracket structure, effectively avoiding the need to enter the well to disassemble and assemble the flow meter. This not only simplifies the disassembly and assembly process but also makes it safer and more reliable, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wellhead maintainable flow meter support device, comprising:

[0006] The support structure installed on the inner sidewall of the well and the mounting bracket for installing the flow meter;

[0007] The support structure includes a first extended support, a second extended support, and a fixed steel pipe. The two ends of the fixed steel pipe are respectively vertically fixed to the ends of the first extended support and the second extended support. A slip ring is sleeved on the outside of the fixed steel pipe. The mounting bracket is detachably connected to the first extended support and the slip ring.

[0008] Preferably, a limiting seat is fitted on the outer side of the second extended bracket, and a locking bolt is provided at the bottom of the limiting seat. One end of the locking bolt passes through the inner cavity of the limiting seat and is threadedly connected to the second extended bracket. A limiting slot is provided at the top of the limiting seat, and the fixing steel pipe is inserted into the limiting slot.

[0009] Preferably, a fixing plate is fixed to the side of the slip ring, and two sets of first U-bolts are provided on the outer side of the mounting bracket. Both ends of the first U-bolts penetrate the fixing plate, and two sets of locking nuts located on both sides of the fixing plate are threaded onto the first U-bolts.

[0010] Preferably, a second U-bolt is provided on the outer side of the upper end of the fixed steel pipe and the mounting bracket, and the end of the second U-bolt passes through the first extended bracket and is threaded with a mounting nut.

[0011] Preferably, a bolt post is fixed at the center of the bottom of the limiting slot, and a threaded hole is opened at the bottom of the fixing steel pipe. The bolt post passes through the threaded hole and is threadedly connected to the threaded hole.

[0012] Preferably, the slip ring has a countersunk hole on its outer side, and a limit bolt is threaded into the countersunk hole. One end of the limit bolt extends inward and abuts against the outer wall of the fixed steel pipe.

[0013] Preferably, both the mounting bracket and the top of the fixed steel pipe are threaded with anti-fall brackets, and the outer diameter of the anti-fall brackets is larger than the inner diameter of the second U-bolt.

[0014] Preferably, the mounting bracket is provided with a scale, and the upper end of the mounting bracket is provided with a marking line on the same outer side as the mounting flow meter.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model anchors the support structure to the inner wall of the well as a fixed support structure for the mounting frame. The mounting frame is then connected to the fixed steel pipe on the support structure via a slip ring. This not only restricts the mounting frame but also allows it to move down along the fixed steel pipe. Operations on the mounting frame and support structure at the wellhead are convenient for moving the mounting frame and flow meter up and down at the wellhead, avoiding downhole operations. This simplifies the process, meets the conditions for daily equipment maintenance, and is safer and more reliable, avoiding potential dangers in downhole operations.

[0017] 2. This utility model uses the cooperation of the first U-bolt and two sets of locking nuts to conveniently restrict the mounting frame and the fixed steel pipe, maintain the stability of the mounting frame in the well, and at the same time, the angle of the mounting frame and the flow meter can be adjusted to ensure that the flow meter beam is in the same direction as the water flow.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The wellhead maintainable current meter support device shown includes:

[0026] The support structure 1 is installed on the inner side wall of the well, and the L-shaped mounting bracket 2 is used to install the flow meter;

[0027] The support structure 1 includes a first extended support 101, a second extended support 102 and a fixed steel pipe 103. The two ends of the fixed steel pipe 103 are respectively vertically fixedly connected to the ends of the first extended support 101 and the second extended support 102. A slip ring 3 is sleeved on the outside of the fixed steel pipe 103. The mounting bracket 2 is detachably connected to the first extended support 101 and the slip ring 3 respectively.

[0028] By anchoring the support structure 1 to the inner wall of the well, it serves as a fixed support structure for the mounting frame 2. Subsequently, the mounting frame 2 is connected to the fixed steel pipe 103 on the support structure 1 via the slip ring 3. This not only restricts the mounting frame 2, but also allows the mounting frame 2 to move down along the fixed steel pipe 103. This facilitates the operation of the mounting frame 2 and the support structure 1 at the wellhead position, making it convenient to move the mounting frame 2 and the flow meter up and down at the wellhead position. This avoids the need for downhole operations, simplifies the process, meets the conditions for daily equipment maintenance, and is also safer and more reliable, avoiding potential dangers in downhole operations.

[0029] Among them, such as Figure 3 As shown:

[0030] A limiting seat 4 is fitted on the outer side of the second extended bracket 102. A locking bolt 5 is provided at the bottom of the limiting seat 4. One end of the locking bolt 5 passes through the inner cavity of the limiting seat 4 and is threadedly connected to the second extended bracket 102. A limiting slot 6 is provided at the top of the limiting seat 4. The fixing steel pipe 103 is inserted into the limiting slot 6. The limiting seat 4 is fixed to the end of the second extended bracket 102 by the locking bolt 5. Then, the fixing steel pipe 103 is fixedly connected with the limiting slot 6.

[0031] Furthermore, such as Figure 4 As shown:

[0032] A fixing plate 7 is fixed to the side of the slip ring 3. Two sets of first U-bolts 8 are provided on the outside of the mounting bracket 2. Both ends of the first U-bolts 8 pass through the fixing plate 7. Two sets of locking nuts 9 located on both sides of the fixing plate 7 are threaded onto the first U-bolts 8. The first U-bolts 8 are connected to the slip ring 3 through the fixing plate 7. Then, the first U-bolts 8 are fixedly connected to the fixing plate 7 through the locking nuts 9. The first U-bolts 8 limit the mounting bracket 2 and maintain the distance between the mounting bracket 2 and the fixed steel pipe 103 to prevent shaking when the mounting bracket moves up and down.

[0033] Preferred, such as Figure 5 As shown:

[0034] The outer sides of the upper end of the fixed steel pipe 103 and the mounting bracket 2 are both provided with second U-bolts 10. The end of the second U-bolt 10 passes through the first extended bracket 101 and is threaded with a mounting nut 11. Through the cooperation of the second U-bolt 10 and the mounting nut 11, the fixed steel pipe 103 and the mounting bracket 2 can be easily locked on the first extended bracket 101 to maintain the stability of the bracket structure 1 and the mounting bracket 2 and the bracket structure 1.

[0035] It is worth noting that, such as Figure 3 As shown:

[0036] A bolt post 12 is fixed at the center of the bottom of the limiting slot 6. A threaded hole 13 is opened at the bottom of the fixing steel pipe 103. The bolt post 12 passes through the threaded hole 13 and is threadedly connected to the threaded hole 13. Through the cooperation of the threaded post, it is convenient to cooperate with the threaded hole 13 at one end of the fixing steel pipe 103 to connect the fixing steel pipe 103 and the limiting seat 4.

[0037] In a further preferred embodiment, such as Figure 4 As shown:

[0038] The slip ring 3 has a countersunk hole on its outer side, and a limit bolt 14 is threaded into the countersunk hole. One end of the limit bolt 14 extends inward and abuts against the outer wall of the fixed steel pipe 103. By tightening the limit bolt 14 on the slip ring 3, the slip ring 3 is restricted to the upper end of the fixed steel pipe 103, so as to prevent the slip ring 3 from falling downward without a limit structure after the installation frame 2 is removed, which would result in no slip ring 3 being used at the wellhead position when the installation frame 2 is reinstalled. Loosening the limit bolt 14 restores the freedom of the slip ring 3 and limits the installation frame 2.

[0039] In addition, such as Figure 5 As shown:

[0040] Both the mounting bracket 2 and the top of the fixed steel pipe 103 are threaded with anti-fall brackets 15. The outer diameter of the anti-fall bracket 15 is larger than the inner diameter of the second U-bolt 10. The anti-fall bracket 15 is designed to prevent the fixed steel pipe 103 and the mounting bracket 2 from slipping due to operational errors when the operator is installing them at the wellhead, which would directly cause the fixed steel pipe 103 and the mounting bracket 2 to fall into the well. When the anti-fall bracket 15 is installed, it sits directly above the second U-bolt 10, preventing the fixed steel pipe 103 and the mounting bracket 2 from falling.

[0041] In this embodiment, as Figure 5 As shown:

[0042] The mounting frame 2 is equipped with a scale 16, and the upper end of the mounting frame 2 is equipped with a marking line 17 on the same outer side as the mounting flow meter. The scale 16 allows for precise control of the descent distance of the mounting frame 2, making it easy to lower the flow meter to the designated position for accurate water flow detection. The marking line 17 allows the operator to control the orientation of the flow meter at the wellhead position, ensuring that the flow meter beam is in the same direction as the water flow.

[0043] In practical use, a first extended bracket 101 and a second extended bracket 102 are pre-anchored to the inner sidewall of the well. When installing the flow meter, the direct structure needs to be assembled. The second U-bolt 10 is placed on the outside of the fixed steel pipe 103, and the fixed steel pipe 103 is pre-installed with the first extended bracket 101 using the mounting nut 11. Then, the fixed steel pipe 103 is moved downwards and inserted into the limiting slot 6 at the top of the limiting seat 4 on the second extended bracket 102. Rotate the fixed steel pipe 103 to thread the bolt post 12 into the threaded hole 13 on the fixed steel pipe 103. Then tighten the mounting nut 11 on the second U-bolt 10 on the outside of the fixed steel pipe 103 to fix the fixed steel pipe 103. Then snap the first U-bolt 8 onto the outside of the mounting bracket 2. Then pass the first U-bolt 8 through the fixed plate 7 and fix the first U-bolt 8 to the fixed plate 7 with the locking nut 9, while keeping the first U-bolt 8 sliding with the mounting bracket 2. Then... The second U-bolt 10 is snapped onto the outside of the mounting frame 2 and pre-installed with the first extended bracket 101 using the mounting nut 11. The flow meter is then installed on the mounting frame 2. The mounting frame 2 is then lowered into the well along the fixed steel pipe 103. The mounting frame 2 remains relatively stable with the fixed steel pipe 103 under the constraint of the slip ring 3 and the second U-bolt 10. The position of the flow meter can be precisely controlled according to the scale 16. After the flow meter reaches the specified depth, the mounting frame 2 is rotated to align the beam direction of the flow meter with the direction of the water flow. Then tighten the mounting nut 11 to fix the mounting frame 2; when removing, simply loosen the mounting nut 11 on the second U-bolt 10 at the upper end of the mounting frame 2, then lift the mounting frame 2 upwards. The slip ring 3 moves upwards synchronously under the traction of the mounting frame 2. After the flow meter moves to the wellhead position, tighten the limit bolt 14 to restrict the slip ring 3. Then loosen the locking nut 9 on the first U-bolt 8 to separate the mounting frame 2 from the fixing plate 7 and the first extended bracket 101, and the flow meter can be removed from the well.
