Description

Technical Field

[0001] This utility model relates to the field of potential acquisition instrument technology, and in particular to a protective device for a potential acquisition instrument. Background Technology

[0002] A potential acquisition instrument, also known as a cathodic protection potential tester, is an intelligent device used to monitor and record the potential value of metal structures (such as pipelines, storage tanks, ships, etc.) in a cathodic protection system. By measuring the potential difference between the metal structure and the reference electrode, it assesses the effectiveness of the cathodic protection system and ensures that the metal is protected from corrosion.

[0003] Potential acquisition instruments are widely used in many fields such as industrial production and scientific research experiments. In actual use, potential acquisition instruments often face vibrations during transportation or operation, which can easily cause internal components to loosen or even be damaged, thus affecting the accuracy of the acquired data. In addition, humid environments can cause the internal circuits of potential acquisition instruments to become damp, leading to short circuits and other faults, affecting the normal operation of the equipment and compromising safety.

[0004] Therefore, a new protective device for the potential acquisition instrument needs to be designed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a protective device for a potential acquisition instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective device for a potential acquisition instrument includes a protective box. An opening and closing door is rotatably installed inside the protective box. Sliding rods are fixedly installed on both inner walls of the protective box via connecting frames. Buffer plates are slidably installed on the outer walls of both sliding rods. Buffer springs are installed on the outer walls of both sliding rods. The two ends of the two buffer springs are elastically connected to the inner wall of the connecting frame on the same side and the bottom wall of the buffer plate, respectively. A mounting plate is fixedly connected to the ends of the two buffer plates. Two damping telescopic rods are fixedly installed on the bottom wall of the protective box, and the telescopic ends of both damping telescopic rods are fixedly connected to the bottom wall of the mounting plate.

[0008] Preferably, the outer wall of the protective box has multiple wiring ports that communicate with the interior, and each wiring port has a junction box fixedly installed inside.

[0009] Preferably, the outer walls on both sides of the protective box are provided with multiple ventilation openings, and rain covers that cooperate with the multiple ventilation openings on the same side are fixedly installed on the outer walls on both sides of the protective box.

[0010] Preferably, the multiple openings on both sides are symmetrically inclined, and the bottoms of both rain covers are open.

[0011] Preferably, a baffle that cooperates with the opening and closing door is fixedly installed inside the protective box, and a sealing gasket that cooperates with the baffle is fixedly installed on the inner wall of the opening and closing door.

[0012] Preferably, an installation frame is fixedly installed on the inner wall of the door, and a moisture-absorbing plate is slidably installed inside the installation frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up components such as buffer plates, buffer springs, and damping telescopic rods, when the potential acquisition instrument is subjected to external vibration or impact, the mounting plate drives the buffer plate to slide along the slide rod, the buffer spring absorbs vibration energy, and the damping telescopic rod consumes energy and suppresses shaking. The two work together to form a multi-stage shock absorption structure, which effectively weakens the transmission of vibration, protects internal components, ensures stable operation of the potential acquisition instrument in complex vibration environments, and reduces data errors and failure risks.

[0015] 2. By setting up components such as rain covers, sealing gaskets, and moisture-absorbing plates, the rain covers, in conjunction with the inclined ventilation openings, can effectively block rainwater and ensure that the equipment is not damaged in heavy rain. The sealing gaskets and baffles fit tightly together, enhancing the airtightness of the enclosure and blocking dust and moisture. The moisture-absorbing plates actively absorb moisture and keep the inside dry. The three work together to resist external humidity, eliminate internal hazards, avoid moisture-related malfunctions, and ensure the stable operation of the potential acquisition instrument in complex environments.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A protective device for a potential acquisition instrument includes a protective box 1. An opening and closing door 2 is rotatably installed inside the protective box 1. Sliding rods 4 are fixedly installed on both inner walls of the protective box 1 through connecting frames 3. Buffer plates 5 are slidably installed on the outer walls of the two sliding rods 4. Buffer springs 6 are installed on the outer walls of the two sliding rods 4. The two ends of the two buffer springs 6 are elastically connected to the inner wall of the connecting frame 3 and the bottom wall of the buffer plate 5 on the same side, respectively. The ends of the two buffer plates 5 are fixedly connected to the mounting plate 7. Two damping telescopic rods 8 are fixedly installed on the bottom wall of the protective box 1. The telescopic ends of the two damping telescopic rods 8 are fixedly connected to the bottom wall of the mounting plate 7.

[0024] Furthermore, the buffer spring 6 is made of high-strength alloy spring steel and undergoes heat treatment to enhance its toughness and fatigue resistance, enabling it to withstand high-frequency vibration and impact. The damping fluid of the damping telescopic rod 8 is made of silicone oil, which has stable viscosity and can automatically adjust the damping force according to the vibration intensity to achieve precise shock absorption.

[0025] The outer wall of the protective box 1 has multiple wiring ports that communicate with the interior, and each wiring port has a junction box 9 fixedly installed inside.

[0026] Furthermore, the junction box 9 is made of flame-retardant engineering plastic and has anti-loosening buckles and waterproof sealing rings inside, which can not only securely fix the wires, but also prevent external moisture and dust from entering the protective box 1.

[0027] Multiple ventilation openings are provided on both sides of the outer wall of the protective box 1, and rain covers 10 that cooperate with the multiple ventilation openings on the same side are fixedly installed on both sides of the outer wall of the protective box 1.

[0028] Furthermore, the rain cover 10 is made of corrosion-resistant aluminum alloy and has an anodized surface, which ensures ventilation and heat dissipation while enhancing the service life and protective performance of the rain cover 10.

[0029] Multiple openings on both sides are symmetrically angled, and the bottoms of both rain covers 10 are open.

[0030] Furthermore, the opening tilt angle was optimized through fluid dynamics calculations and set to 45°, which allows for efficient air convection within the protective box 1, accelerating heat dissipation.

[0031] The protective box 1 has a baffle 11 that cooperates with the opening and closing door 2, and the inner wall of the opening and closing door 2 has a sealing gasket 12 that cooperates with the baffle 11.

[0032] Furthermore, the sealing gasket 12 is made of high-temperature resistant and aging-resistant silicone rubber material, which can maintain good elasticity and sealing performance under different temperature environments, effectively blocking external dust and moisture.

[0033] An installation frame 13 is fixedly installed on the inner wall of the door 2, and a moisture-absorbing plate 14 is slidably installed inside the installation frame 13.

[0034] Furthermore, the moisture-absorbing plate 14 is made of honeycomb activated carbon material, which has a rich internal pore structure and high moisture absorption efficiency. When the moisture-absorbing plate 14 reaches saturation, it can be regenerated by heating and reused, reducing maintenance costs.

[0035] When using this utility model, after fixing the potential acquisition device on the mounting plate 7, connect the potential acquisition device's line to the external equipment through the junction box 9 at the wiring port on the outer wall of the protective box 1, ensuring that the line connection is stable and the interface is well sealed to prevent dust and moisture from entering. Then, close the opening and closing door 2 so that the sealing gasket 12 on the inner wall of the opening and closing door 2 fits tightly with the baffle 11 inside the protective box 1, enhancing the sealing performance of the protective box 1, and completing the installation preparation work.

[0036] During the use of the device, if vibration or impact occurs, the mounting plate 7 will cause the buffer plate 5 to slide on the slide rod 4. The buffer spring 6 will quickly generate elastic deformation to absorb the vibration energy. At the same time, the damping telescopic rod 8 will play a damping role and dissipate the vibration energy. The two work together to effectively reduce the impact of vibration on the potential acquisition instrument and ensure the safe and stable operation of its internal components. When the potential acquisition instrument generates heat during operation, the symmetrically inclined ventilation openings on both sides of the protective box 1, together with the open rain cover 10 at the bottom, promote air circulation and dissipate heat, preventing the equipment from overheating. To mitigate performance degradation, the rain cover 10 can shield the device from rainwater during heavy rain, preventing it from entering through the ventilation openings and thus avoiding short circuits, component damage, and other malfunctions caused by rainwater intrusion. If the internal environment of the protective box 1 is humid, the moisture-absorbing plate 14 installed in the mounting frame 13 on the inner wall of the opening and closing door 2 will absorb moisture and keep the interior dry. When the moisture-absorbing plate 14 is saturated with water, the opening and closing door 2 can be opened, and the moisture-absorbing plate 14 can be removed for replacement or drying to maintain a good moisture-proof effect and ensure that the potential acquisition device is always in a suitable working environment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
