Description

Technical Field

[0001] This utility model relates to a recorder, and more particularly to a modular lightning current detection recorder applied in the field of electrical equipment. Background Technology

[0002] The impact of lightning disasters is becoming increasingly significant in many fields such as modern power, communications, and construction. As a powerful natural discharge phenomenon, lightning generates extremely high instantaneous amplitude lightning currents. The overvoltages, overcurrents, and electromagnetic pulses generated by lightning can cause serious damage to power systems and other systems. Various lightning current detection and recording devices are available on the market.

[0003] Chinese patent CN210072715U discloses an easy-to-install lightning protection detection recorder, including a detection device and a housing connected to the detection device by wires. The detection device includes a connecting shaft, and a circuit board is connected below the connecting shaft. The circuit board is fixedly mounted on a first fixed base. The first fixed base is fixedly connected to a second fixed base through a detection rod. A current transformer is provided inside the housing, and the current transformer is connected to a current-voltage converter through wires.

[0004] Because lightning current detection equipment is often installed outdoors in harsh environments, it needs to withstand long-term exposure to wind, rain, sun, and extreme temperature changes. However, many devices have poorly designed sealing structures, using only simple sealing strips or outer shells. Over long-term use, the sealing strips are prone to aging and deformation, and gaps may appear at the seams of the outer shell due to thermal expansion and contraction. This allows rainwater, dust, and moisture to easily penetrate the equipment, causing damage to electronic components, short circuits, and other malfunctions, severely affecting the equipment's lifespan and operational stability. Utility Model Content

[0005] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the sealing structure design of many devices is unreasonable. They only use simple sealing strips or outer shells for packaging. During long-term use, the sealing strips are prone to aging and deformation, and gaps may also appear at the joints of the outer shell due to thermal expansion and contraction, making it easy for rainwater, dust and moisture from the outside to penetrate into the inside of the device.

[0006] To address the aforementioned problems, this utility model provides a modular lightning current detection recorder, comprising an instrument frame, a sealing baffle hinged to the front end of the instrument frame, a locking groove formed at the front end of the instrument frame, a sealing waterproof frame strip fixedly connected to the end of the sealing baffle near the instrument frame, a monitoring inner block fixedly connected to the inner end of the instrument frame, a controller fixedly connected to the lower end of the monitoring inner block, a bottom frame fixedly connected to the inner end of the sealing waterproof frame strip near the sealing baffle, a first inner layer fixedly connected to the end of the bottom frame away from the sealing baffle, a second inner layer fixedly connected to the front end of the first inner layer, multiple storage compartments formed at the inner end of the first inner layer, the inner ends of the storage compartments filled with a number of solidified internal materials, and the inner ends of the second inner layer filled with a number of water-swellable internal spheres.

[0007] In the aforementioned modular lightning current detection recorder, the sealing baffle in this solution is closed to the instrument frame via a hinge connection, and the sealing waterproof frame strip and the locking groove are tightly fitted to form a sealing barrier to prevent dust, rainwater, foreign objects and other contaminants from entering the equipment.

[0008] As a further improvement of this application, an electrical frame-type guide rail is fixedly connected to one end of the sealing baffle near the instrument frame, and the electrical frame-type guide rail is located on the inner side wall of the sealing and waterproof frame strip.

[0009] As a further improvement of this application, the output end of the electric frame-type guide rail is provided with a sliding inner block, and a protruding cylinder is fixedly connected to the end of the sliding inner block away from the electric frame-type guide rail.

[0010] As a further improvement of this application, a plurality of sensors are provided at the outer end of the protruding cylinder, and the number of sensors is four.

[0011] As another improvement of this application, a reinforcing inner layer is fixedly connected to the outer side of the first inner layer and the second inner layer, and a toothed outer surface is fixedly connected to the outer end of the reinforcing inner layer.

[0012] As a further improvement to this application, the sealing and waterproof frame strip matches the locking groove, and the rear end of the instrument frame is symmetrically fixedly connected with the mounting back plate on the upper and lower sides.

[0013] As a further improvement to this application, locking bolts are symmetrically installed at both ends of the mounting back plate, and the instrument frame and the sealing baffle are interlocked.

[0014] In summary, in this solution, the sealing baffle is closed to the instrument frame via a hinged connection, and the sealing waterproof frame strip fits tightly with the locking groove, forming the first physical sealing barrier to prevent dust, rainwater, foreign objects, etc., from entering the equipment. When the sealing waterproof frame strip is worn or damaged due to long-term use or external impact, causing water vapor or liquid to seep in, the internal multi-layer protection system is activated. The superabsorbent polymer material in the water-swelling inner sphere quickly absorbs water and expands, filling the micro-gaps. At the same time, the water-curing sealant in the storage compartment is released under the action of damage stress, seeps into the damaged area through capillary action, and cures at room temperature to form a new sealing layer, thereby maintaining the sealing performance of the equipment and protecting the internal electronic components from the external environment. During equipment operation, when the sensor detects a sealing abnormality, it can immediately trigger the equipment's audible and visual alarm device, and at the same time send a fault code containing information such as the abnormal location and damage type to the remote monitoring terminal through the communication module.

[0024] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] First implementation method:

[0026] Figures 1-3 , Figures 6-7 A modular lightning current detection recorder is shown, including an instrument frame 1. A sealing baffle 3 is hinged to the front end of the instrument frame 1. A locking groove 5 is opened at the front end of the instrument frame 1. A sealing and waterproof frame strip 6 is fixedly connected to the end of the sealing baffle 3 near the instrument frame 1. A monitoring inner block 4 is fixedly connected to the inner end of the instrument frame 1. A controller 16 is fixedly connected to the lower end of the monitoring inner block 4. A structural bottom layer 17 is fixedly connected to the inner end of the sealing and waterproof frame strip 6 near the sealing baffle 3. A first inner layer 18 is fixedly connected to the end of the structural bottom layer 17 away from the sealing baffle 3. A second inner layer 11 is fixedly connected to the front end of the first inner layer 18. A plurality of material storage compartments 14 are opened at the inner end of the first inner layer 18. A plurality of solidified inner materials 13 are filled at the inner end of the material storage compartments 14. A plurality of water-swellable inner balls 12 are filled at the inner end of the second inner layer 11.

[0027] Figures 1-3 , Figures 6-7 The outer sides of the first inner layer 18 and the second inner layer 11 are fixedly connected to a reinforcing inner layer 19. The outer end of the reinforcing inner layer 19 is fixedly connected to a toothed outer surface 20. The sealing and waterproof frame strip 6 matches the locking groove 5. The rear end of the instrument frame 1 is symmetrically fixedly connected to the upper and lower sides of the mounting back plate 2. The left and right ends of the mounting back plate 2 are symmetrically installed with locking bolts 15. The instrument frame 1 and the sealing baffle 3 are interlocked.

[0028] Figures 1-3 , Figures 6-7The modular lightning current detection recorder operates by using an instrument frame 1 as the core load-bearing structure, which is fixed to the required monitoring position by locking bolts 15 on the mounting back plate 2, providing stable support for overall operation. When lightning current is generated, the monitoring inner block 4 converts the received magnetic field signal into an electrical signal, accurately acquiring key parameters such as the peak value and waveform duration of the lightning current, and storing and recording these data. Regarding the sealing and protection mechanism, the sealing baffle 3 and the instrument frame 1 are hinged to achieve opening and closing. When closed, the precise fit between the sealing waterproof frame strip 6 and the locking groove 5 forms the first physical barrier. The internal structure of the sealing waterproof frame strip 6, including the bottom layer 17, the first inner layer 18, and the water-swellable inner sphere 12, constitutes a multi-layered protection system: under normal conditions, the water-swellable inner sphere 12 maintains a stable shape; if the sealing waterproof frame strip 6 is worn or damaged due to long-term use or external impact, causing water vapor or liquid to seep in, the high-resolution... The absorbent material rapidly expands in volume, filling microscopic gaps. The cured inner material 13 within the storage compartment 14, a water-curing sealant, is released under stress and fills the damaged area through capillary action. It completes the curing process at room temperature, forming a new sealing layer. This automatic repair mechanism requires no manual intervention, promptly sealing damaged areas and maintaining the equipment's sealing performance. This ensures the equipment's sustainable and stable operation in harsh environments, reducing the probability of equipment damage due to seal failure. The reinforced inner layer 9 and the toothed outer layer 20 effectively enhance the mechanical strength and friction when the sealing waterproof frame 6 engages with the locking groove 5. During long-term use, this structure prevents the sealing structure from loosening or failing due to external forces, further ensuring the durability of the equipment's sealing performance. It also improves the overall impact and wear resistance of the equipment, extending its service life.

[0029] Second implementation method:

[0030] Figures 4-5A modular lightning current detection recorder is shown. An electrically conductive frame-shaped guide rail 7 is fixedly connected to one end of a sealing baffle 3 near the instrument frame 1. The electrically conductive frame-shaped guide rail 7 is located on the inner wall of a sealed waterproof frame strip 6. A sliding inner block 8 is provided at the output end of the electrically conductive frame-shaped guide rail 7. A protruding cylinder 9 is fixedly connected to the end of the sliding inner block 8 away from the electrically conductive frame-shaped guide rail 7. Multiple sensors 10 are provided at the outer end of the protruding cylinder 9. The number of sensors 10 is four. When the sealed waterproof frame strip 6 is damaged, causing abnormal internal environmental parameters, the corresponding sensors 10 can collect data changes through built-in temperature and humidity sensors or pressure sensors. The controller 16 receives the monitoring data from each sensor 10 in real time and judges the sealing abnormality based on a threshold comparison algorithm. When a parameter is detected to exceed the normal range, the controller 16 triggers an audible and visual alarm device through an internal communication protocol and sends the data to a remote monitoring terminal via a wireless communication module. This facilitates timely and targeted maintenance by staff, reduces equipment downtime, lowers maintenance costs, and improves the efficiency and reliability of equipment operation and maintenance.

[0031] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
