Description

Technical Field

[0001] This utility model relates to the field of relay protection technology, specifically a relay protection pressure plate anti-accidental contact structure. Background Technology

[0002] In the operation of power systems, relay protection devices, as core components ensuring the safety and stability of the power grid, directly determine the timeliness and accuracy of fault response. Relay protection circuit boards are key operational components for enabling / disabling protection functions and switching setting values, and are widely used in power facilities such as substations and distribution rooms. With the increasing automation of power systems, the number of relay protection circuit boards is constantly increasing, and their installation environment is becoming increasingly complex. They not only need to adapt to equipment layouts of different voltage levels but also need to cope with the effects of various environmental factors such as dust and humidity. Therefore, higher requirements are placed on the protective performance and operational safety of the circuit board structure. Currently, most mainstream relay protection circuit boards are arranged through independent installation or simple frame fixing. While this meets basic functional requirements, how to balance protection and prevention of accidental activation during long-term operation has become an important research direction for ensuring the stable operation of power systems.

[0003] Existing relay protection pressure plates lack sufficient protection against accidental activation. Traditional pressure plates are often exposed or only covered by simple covers, lacking dedicated locking mechanisms. This makes them susceptible to accidental activation or deactivation due to human error or external impact, potentially leading to malfunctions or failures to operate the protection device, and in severe cases, escalating power grid faults. Furthermore, the imbalance between ease of operation and stability further reduces the reliability of the pressure plate operation. Therefore, we propose a relay protection pressure plate anti-accidental activation structure to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a relay protection pressure plate anti-accidental contact structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a relay protection pressure plate anti-accidental contact structure, including a mounting base, a box body fixed at the front end of the mounting base, a ventilation hole on the side of the box body and a box cover connected to the upper end via a rotating shaft, a lock body installed inside the box cover, and a locking clip sleeved on the outside of the lock body.

[0006] Preferably, the mounting base has openings at its four corners, and the mounting base is integrally formed with the box body, which facilitates stable installation, adapts to multiple scenarios, and improves installation flexibility.

[0007] Preferably, the two sets of ventilation holes are located on both sides of the box and are covered with dustproof nets to dissipate heat and prevent dust, ensuring good performance of the pressure plate and good contact with the contacts.

[0008] Preferably, the lid is made of anti-static acrylic sheet material, which protects the components from static electricity, and the transparent design facilitates inspection.

[0009] Preferably, the outer sleeve of the rotating shaft is fixed to the housing, the inner shaft is fixed to the housing cover, the rotating shaft is equipped with damping, and the housing cover can be suspended, making it convenient for maintenance personnel to work with both hands.

[0010] Preferably, a handle is installed on the outside of the box lid, and a magnetic strip is installed at each contact point between the box lid and the box body. The handle facilitates operation, and the magnetic strip enhances sealing and dust prevention.

[0011] Preferably, the upper end of the lock body is cylindrical, and the lower end of the lock body is L-shaped and fixedly connected to the cover. The left side of the lock clip is annular and movably fitted onto the lock body, with damping at the fitting point. The other end of the lock clip is L-shaped and engages with the corresponding slot on the cover. The right side of the lock clip is fixedly connected to the lock cylinder, which movably engages with the cover. A key is inserted into the right side of the lock cylinder to securely lock the cover, prevent unauthorized operation, and solve the problem of accidental activation.

[0012] This utility model provides a relay protection pressure plate anti-accidental touch structure, which has the following beneficial effects:

[0013] This structure features an integrated design where the mounting base and housing are molded as one piece, significantly enhancing overall connection strength and preventing housing misalignment caused by loose components during long-term use. The four corner openings on the base allow it to adapt to various power facility installation scenarios, such as substations and power distribution rooms, while eliminating multiple component assembly steps and effectively improving production and installation efficiency. The magnetic strip at the contact point between the cover and housing ensures a tight seal, and combined with ventilation holes on both sides of the housing equipped with dust filters, it not only prevents dust and impurities from entering the interior, preventing poor contact at the pressure plate contacts, but also creates air convection to accelerate heat dissipation, ensuring long-term stable operation of the pressure plate.

[0014] The lid is made of anti-static acrylic sheet, which prevents static electricity from damaging internal electronic components during opening and closing. Its transparency allows staff to directly observe the pressure plate's deployment and retraction status without opening the lid. The handle on the outside of the lid provides a convenient point of force for opening and closing, especially when wearing protective gloves. The damping design at the hinge ensures a slow and smooth opening and closing process, reducing collision noise, and allows the lid to be suspended, further improving the user experience and efficiency.

[0015] The specialized locking mechanism achieves a secure lock through the cooperation of the L-shaped lock body and the locking clip. Unlocking is achieved simply by inserting a key into the lock cylinder, effectively preventing unauthorized personnel from accidentally opening the cover and causing malfunctions of the relay protection pressure plate, thus reducing the risk of power grid failures at the source. The damping design at the connection between the locking clip and the lock body prevents the locking clip from rotating freely when not in operation, ensuring a stable locked state. The overall design incorporates multiple layers of protection, including dustproof, anti-static, and sealing features, comprehensively improving the safety and reliability of the relay protection pressure plate operation and extending the equipment's service life.

[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. 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a relay protection pressure plate anti-accidental contact structure, including a mounting base 1, a box body 2 fixed at the front end of the mounting base 1, a ventilation hole 3 on the side of the box body 2 and a box cover 4 connected to the upper end through a rotating shaft 5, a lock body 8 installed inside the box cover 4, and a locking clip 7 sleeved on the outside of the lock body 8.

[0024] The mounting base 1 has openings at the four corners. The mounting base 1 and the box body 2 are integrally formed. The openings at the four corners make it easy to install the whole structure stably in the designated position of power facilities such as substations and power distribution rooms by means of bolts and other fasteners, which can adapt to different installation scenario requirements.

[0025] Two sets of ventilation holes 3 are opened on both sides of the box body 2 and dustproof nets are installed on the surface. The symmetrically opened ventilation holes 3 can form air convection, accelerate the heat dissipation inside the box body 2, and prevent the relay protection pressure plate from affecting the performance due to long-term operation heat. The dustproof nets installed on the surface can effectively block external dust from entering the box body 2 through the ventilation holes 3, and prevent dust from adhering to the pressure plate contacts and causing poor contact.

[0026] The cover 4 is made of anti-static acrylic sheet. The anti-static material can prevent static electricity from being generated by friction during the opening and closing of the cover 4, and prevent static electricity from damaging the electronic components of the relay protection pressure plate inside the box body 2, thus ensuring the safety of equipment operation. The transparency of the acrylic sheet allows the staff to directly observe the deployment and retraction status of the internal pressure plate without opening the cover 4, improving the convenience of inspection.

[0027] The outer shaft 5 is fixed to the housing 2, and the inner shaft is fixed to the housing cover 4. The shaft 5 is equipped with damping, which allows the housing cover 4 to be suspended after opening, making it convenient for maintenance personnel to operate with both hands.

[0028] A handle 6 is installed on the outside of the lid 4. Magnetic strips are installed at the contact points between the lid 4 and the box body 2. The handle 6 provides a convenient force point for staff to open the lid 4, which can improve the ease of operation, especially in scenarios that require frequent operation or wearing protective gloves. The magnetic strips can make the lid 4 and the box body 2 adhere tightly when closed, enhance the sealing performance, and effectively prevent dust and other impurities from entering the interior of the box body 2.

[0029] The upper end of the lock body 8 is cylindrical, and the lower end of the lock body 8 is L-shaped and fixedly connected to the cover 4. The left side of the lock clip 7 is annular and movably sleeved on the lock body 8, with damping at the sleeve. The other end of the lock clip 7 is L-shaped and engages with the corresponding slot on the cover 2. The right side of the lock clip 7 is fixedly connected to the lock cylinder 9, which movably engages with the cover 4. A key 10 is inserted into the right side of the lock cylinder 9. The L-shaped fixing structure of the lock body 8 and the L-shaped engaging structure of the lock clip 7 work together to achieve a secure lock between the cover 4 and the cover 2. Combined with the lock cylinder 9 controlled by the key 10, it can effectively prevent unauthorized personnel from accidentally opening the cover 4 and causing the pressure plate to be accidentally activated, thus solving the problem of insufficient anti-accidental activation capability of traditional pressure plates.

[0030] Working principle: In use, the entire structure is first fixed in the designated position through the four corner holes of the mounting base 1, and the relay protection pressure plate is placed inside the box body 2. Under normal conditions, the box cover 4 is tightly closed to the box body 2 by magnetic adhesive strips, the L-shaped end of the lock 7 engages with the box body 2's slot, and the key 10 is inserted into the lock cylinder 9 to lock the lock 7 to prevent accidental activation. When the pressure plate needs to be operated, the key 10 is used to unlock the lock cylinder 9, the lock 7 is rotated to disengage from the slot, and the handle 6 is held to open the box cover 4 along the rotating shaft 5. During operation, the dustproof mesh of the ventilation holes 3 on both sides of the box body 2 ensures heat dissipation and prevents dust, and the anti-static acrylic box cover 4 prevents static electricity from damaging the components, achieving a combination of safety protection and convenient operation.
