Description

Technical Field

[0001] This utility model relates to the field of pressure gauge technology, and in particular to a shock-resistant pressure gauge for oil wells. Background Technology

[0002] A shock-resistant pressure gauge is a pressure measuring instrument that maintains a stable reading under conditions of strong vibration or impact. It typically reduces the effects of vibration through fluid filling, shock-resistant structures, or special designs. Compared to ordinary pressure gauges, shock-resistant pressure gauges have stronger shock and vibration resistance, making them suitable for industrial or oil well environments with severe mechanical vibration.

[0003] However, existing pressure gauges typically rely on robust mechanical structures and sturdy housings for shock resistance. But in environments with strong vibrations, these measures cannot completely eliminate the impact of vibration on gauge readings. Traditional designs often neglect the effects of vibration on internal components, particularly the pointer and dial, leading to unstable readings. Furthermore, while some designs offer some damping through elastic materials, the damping effect of existing technologies is limited for high-frequency or prolonged continuous vibrations, making it impossible to maintain high-accuracy measurement results over extended periods.

[0004] To address the above problems, a shock-resistant pressure gauge for oil wells is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a shock-resistant pressure gauge for oil wells, aiming to solve the problems of unstable readings and insufficient shock resistance performance of an existing shock-resistant pressure gauge for oil wells in environments with strong vibrations.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an anti-vibration pressure gauge for oil wells, comprising a pressure gauge, wherein the bottom of the pressure gauge is fixedly connected to an installation bolt, an upper fixing plate and a lower fixing plate are sleeved on the outside of the installation bolt, the lower fixing plate is snapped into the inside of the upper fixing plate, and two shock-absorbing components are symmetrically arranged between the bottoms of the two.

[0007] The shock absorption assembly includes an upper mounting plate, with rotating seats fixedly connected to both sides of the bottom of the upper mounting plate, and rotating rods rotatably connected inside the rotating seats. Damping rods are provided at both ends of the bottom of the upper mounting plate, and lower mounting blocks are fixedly connected to the bottom of the two damping rods. A sliding rod is installed between the interiors of the two lower mounting blocks, and two sliding sleeves are slidably connected inside the sliding rod, with a force-bearing spring between them.

[0008] As a further description of the above technical solution:

[0009] The bottom of the rotating rod is rotatably connected inside the sliding sleeve.

[0010] As a further description of the above technical solution:

[0011] The force-bearing spring is sleeved on the outside of the slide rod, and the two ends of the force-bearing spring are respectively fixedly connected to the opposite side between the two slide sleeves.

[0012] As a further description of the above technical solution:

[0013] The bottoms of the two lower mounting blocks are fixedly connected to the inner bottom wall of the lower fixing plate.

[0014] As a further description of the above technical solution:

[0015] The pressure gauge has a pointer internally connected to it, and a transparent casing is installed inside the pressure gauge.

[0016] As a further description of the above technical solution:

[0017] The pressure gauge has an internal filling chamber, which is filled with silicone oil and glycerin.

[0018] As a further description of the above technical solution:

[0019] An elastic damping layer is installed between the transparent outer shell and the interior of the pressure gauge, and the elastic damping layer is located on the outside of the filling chamber.

[0020] As a further description of the above technical solution:

[0021] The mounting bolt has a nut installed at its top and a thread at its bottom.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, a shock-absorbing component is installed inside the fixed plate, using the action of a spring to effectively absorb vibrations generated by collisions. This not only provides immediate buffering under vibration or external impact, but also ensures the stability of the measurement system, avoiding errors caused by vibration.

[0024] 2. In this invention, by filling the pressure gauge with a high-viscosity damping fluid, the impact of vibration on the dial and pointer can be effectively reduced, enhancing measurement stability. The presence of the high-viscosity liquid not only absorbs external vibrations but also stabilizes the pointer's oscillation, reducing reading errors caused by vibration. Furthermore, the liquid flow control and temperature and pressure compensation design further optimize the anti-vibration effect, ensuring that the pressure gauge can still provide accurate and stable measurement results in vibrating environments.

[0030] 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.

[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an anti-vibration pressure gauge for oil wells, comprising a pressure gauge 1 designed with enhanced anti-vibration performance to adapt to environments with strong vibrations, such as oil wells. A mounting bolt 4 is fixedly connected to the bottom of the pressure gauge 1, with a nut installed at the top of the mounting bolt 4 to further enhance its stability with the pressure gauge 1 and ensure that the equipment does not loosen during long-term operation. The bottom end of the mounting bolt 4 is threaded to facilitate the secure fixing of the pressure gauge 1 to the work platform or equipment, ensuring stable installation and use of the pressure gauge 1. An upper fixing plate 2 and a lower fixing plate 3 are fitted around the outside of the mounting bolt 4. These two plates, through precise fitting, enhance the overall rigidity and stability of the pressure gauge 1, preventing vibration from affecting the internal instruments. The lower fixing plate 3 is snapped into the interior of the upper fixing plate 2, ensuring a secure connection between the two and preventing loosening. Furthermore, two shock-absorbing components 6 are symmetrically arranged between the bottoms of the two components. These shock-absorbing components 6 absorb external vibrations and impacts through springs and other shock-absorbing materials, reducing the intensity of vibration transmitted to the inside of the pressure gauge 1 and ensuring stable operation of the pressure gauge 1.

[0032] Reference Figure 2 - Figure 3The shock absorber assembly 6 includes an upper mounting plate 601, which serves as a support component for the entire shock absorber system. Rotary seats 602 are fixedly connected to both sides of the bottom of the upper mounting plate 601. The rotating seats 602 provide support and allow rotation, ensuring that the shock absorber assembly 6 can freely adjust its position during vibration and absorb external impacts. A rotating rod 604 is rotatably connected inside the rotating seat 602. The rotating rod 604, as a key component connecting the rotating seat 602 and the sliding sleeve 605, can rotate during vibration, thereby dispersing and buffering the vibration force. The sliding sleeve 605, as a sliding component, connects with the rotating rod 604 to absorb and disperse vibration energy, reducing the impact on the pressure gauge 1. Damping rods 603 are provided at both ends of the bottom of the upper mounting plate 601. These two damping rods 603 reduce vibration and improve system stability, effectively reducing the intensity of vibration transmitted to the lower fixed plate 3. Both damping rods 603 have lower mounting blocks 606 fixedly connected to their bottoms. The bottoms of the two lower mounting blocks 606 are fixedly connected to the inner bottom wall of the lower fixed plate 3, ensuring the stable operation of the shock absorber 6 and maintaining its function during vibration. A slide rod 607 is installed between the interior of the two lower mounting blocks 606. Two sliding sleeves 605 are slidably connected inside the slide rod 607. The sliding performance of the sliding sleeves 605 ensures the transmission and effective absorption of vibration energy between them. A force spring 608 is provided between the two, sleeved on the outside of the slide rod 607. The two ends of the force spring 608 are fixedly connected to the opposite side of the two sliding sleeves 605, respectively. The force spring 608 provides elastic restoring force, ensuring that the shock absorber 6 can return to its original position after being impacted.

[0033] Reference Figure 1 - Figure 2 The pressure gauge 1 has an internally rotating pointer 11 that displays the pressure reading and indicates the reading position as the pressure changes. A transparent housing 12 is installed inside the pressure gauge 1. This housing not only protects the internal structure but also provides a clear view, allowing the operator to easily observe the movement of the pointer 11. The pressure gauge 1 has an internal filling chamber that holds shock-absorbing liquid silicone oil or glycerin, effectively reducing the impact of vibration on the internal pointer 11 and ensuring its smooth operation, thus guaranteeing accurate readings even in vibrating environments. An elastic shock-absorbing layer 5 is installed between the transparent housing 12 and the interior of the pressure gauge 1. This layer acts as a buffer, absorbing and reducing the force transmitted from external impacts to the interior of the pressure gauge 1, further enhancing its shock resistance.

[0034] Working Principle: During operation, pressure gauge 1 is connected to the oil well working platform via mounting bolts 4. The bottom of mounting bolt 4 is threaded into the desired position, and its top is fixed to pressure gauge 1 with a nut. Upper fixing plate 2 and lower fixing plate 3 are fitted onto the outside of mounting bolt 4, with the lower fixing plate 3 snapped into the inside of upper fixing plate 2. Two shock-absorbing components 6 are symmetrically arranged between their bottoms. The shock-absorbing components 6 include an upper mounting plate 601, a rotating seat 602, a rotating rod 604, and a sliding sleeve 605. The rotating rod 604 connects the rotating seat 602 to the sliding sleeve 605. The sliding sleeve 605 slides on the outside of the sliding rod 607, and the two sliding sleeves 605 are connected by a force-bearing spring 608. A pointer 11 is rotatably connected inside pressure gauge 1, and the pointer 11 is connected to the internal measuring system via a rotating shaft. A transparent outer shell 12 is installed inside pressure gauge 1, and an elastic shock-absorbing layer 5 is provided between the outer shell and the inner wall of pressure gauge 1. A filling chamber is opened inside pressure gauge 1, and the chamber is filled with silicone oil and glycerin.
