Description
Technical Field
[0001] This application relates to the technical field of electricity meter protection, and in particular to a high-protection single-phase electricity meter. Background Technology
[0002] Currently, single-phase electricity meters play an important role in the field of electricity metering.
[0003] With the rapid development of the economy, the demand for electricity from all walks of life is increasing, and the uneven distribution of electricity consumption at different times is becoming increasingly serious. The terminals of the electricity meter are connected to the external cables and loads. When users use a large load, a large current is generated. This large current generates a lot of heat at the terminals of the electricity meter, causing the temperature of the terminals to rise continuously until the electricity meter burns out. During peak electricity consumption periods, the heavy load on the electricity meter is also the root cause of the electricity meter overheating, leading to damage or even spontaneous combustion. The required functions of the electricity meter will change depending on the environment in which it is used. In some humid environments, the electricity meter is more prone to damage or even spontaneous combustion. Regarding the aforementioned technologies, the applicant believes that traditional single-phase electricity meters have a weak ability to prevent damage. Utility Model Content
[0004] To address the aforementioned technical problems, this application provides a high-protection single-phase energy meter.
[0005] This application provides a high-protection single-phase energy meter, which adopts the following technical solution: A high-protection single-phase energy meter includes a meter body shell, a fixing mechanism, a locking mechanism, and a supporting and reinforcing mechanism. One side cover of the meter body shell is detachably connected, and the remaining parts in contact with the cover are provided with a first groove, each groove containing a first rubber pad. The fixing mechanism is mounted on the meter body shell and is detachably connected to it. The locking mechanism is mounted on the meter body shell and is fixedly connected to it. The supporting and reinforcing mechanism is mounted on the meter body shell and is fixedly connected to it.
[0006] By adopting the above technical solutions, the outer casing of the meter provides physical protection and achieves a seal to prevent rainwater and dust from entering. The fixing mechanism enables the installation and position adjustment of the electricity meter. The locking mechanism uses a combination lock and a mechanical lock cylinder to form a double lock, preventing illegal disassembly, tampering with internal components or electricity theft. The support and reinforcement mechanism provides an extra layer of protection for the electricity meter, blocking rainwater and dust from entering, and draining any water that seeps into the first layer of protection, keeping the inside of the meter dry.
[0007] Preferably, the fixing mechanism includes multiple bracket plates and adjusting nuts. Bolts are provided at the four corners of the back of the watch body shell, and one end of the bolts is fixedly connected to the watch body shell. The adjusting nuts are rotatably connected to the bracket plates, and the adjusting nuts are threadedly connected to the bolts at the four corners of the watch body shell. Multiple mounting holes are provided on the surface of each bracket plate.
[0008] Preferably, each adjusting nut in the fixing mechanism has a threaded hole on one side, and a locking bolt is provided in the threaded hole. The locking bolt and the threaded hole are threadedly connected.
[0009] By adopting the above technical solution, the adjusting nut is threadedly connected to the bolt on the back of the meter body. By rotating the adjusting nut, the distance between the bracket plate and the meter body can be adjusted, so as to make fine adjustments to the height or angle of the meter installation position. The bracket plate, as the main support structure of the fixing mechanism, is fixedly connected to the external mounting surface through the mounting holes on the plate. The locking bolt is installed in the threaded hole of the adjusting nut. After the adjusting nut is adjusted to the appropriate position, tightening the locking bolt can fix the adjusting nut and prevent it from loosening due to vibration and other factors, so as to ensure that the meter is installed stably.
[0010] Preferably, the locking mechanism includes a combination lock and a buckle. One side of the buckle is mounted on the watch case and is hinged to the watch case. The combination lock is mounted on the watch case and is fixedly connected to the watch case. Its electronic lock core is detachably connected to the other end of the buckle.
[0011] Preferably, the combination lock has a mechanical lock cylinder on one side, the mechanical lock cylinder is equipped with a corresponding key, the connection position between the mechanical lock cylinder and the buckle is the same as the connection position between the electronic lock cylinder and the buckle, and the mechanical lock cylinder and the buckle are detachably connected.
[0012] By adopting the above technical solution, the locking and unlocking of the buckle is controlled by the electronic lock cylinder. The correct password must be entered to open it, preventing unauthorized personnel from disassembling the electricity meter. One end of the buckle is connected to the meter body shell through a hinge and can be rotated to open and close. The other end is detachably connected to the electronic lock cylinder or mechanical lock cylinder of the combination lock to lock the cover. The mechanical lock cylinder serves as a backup unlocking method. When the combination lock fails, the matching key is used to control the buckle through the mechanical lock cylinder to ensure that the electricity meter can still be opened in an emergency.
[0013] Preferably, the support and reinforcement mechanism includes a protective layer and a pressure regulating valve. The protective layer is located on the upper inner side of the watch body shell. A slightly inclined V-shaped support plate is provided on the upper inner layer of the watch body shell. The space formed between the upper part of the V-shaped support plate and the top of the watch body shell is the protective layer. The V-shaped support plate is fixedly connected to the inner wall of the watch body shell. A second groove is provided at the outer contact point of the V-shaped support plate with the cover plate. A second rubber pad is installed inside the second groove. A pressure regulating valve is provided on the watch body shell at the protective layer position. The pressure regulating valve is fixedly connected to the watch body shell.
[0014] By adopting the above technical solution, the protective layer is formed by the space between the top of the meter casing and the slightly tilted V-shaped support plate. The tilted design of the V-shaped support plate can stably support the entire box. At the same time, the air pressure regulating valve can draw out some air, so that a negative pressure state is formed on the upper side. At this time, the meter casing can be better sealed. Meanwhile, the air layer formed on the upper side can insulate some heat, so that the electricity meter is in a low-temperature environment. The second rubber pad is installed in the second groove on the outside of the V-shaped support plate to fill the gap between the cover plate and the V-shaped support plate.
[0015] Preferably, the top upper surface of the watch body shell is uniformly covered with anti-climb spikes, and the anti-climb spikes are fixedly connected to the top upper surface of the watch body shell.
[0016] By adopting the above technical solution, the top anti-climb spikes prevent birds from landing on them, prevent birds from pecking at the meter casing, prevent foreign objects from being placed there, ensure the structural integrity of the meter casing and internal components, and maintain the normal operation and protection performance of the electricity meter.
[0017] Preferably, the cover plate is a transparent cover plate at the position where the electricity meter displays the value, and the transparent cover plate portion is fixedly connected to other cover plate portions.
[0018] By adopting the above technical solution, the transparent cover plate covers the position of the electricity meter display value. The transparent material allows the operator to clearly read the electricity meter data without opening the cover plate, improving the convenience of use. It also has the same protective performance as other cover plate parts, protecting the display screen or dial from the influence of the external environment.
[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. The outer casing of the meter provides physical protection and achieves a seal to prevent rainwater and dust from entering. The fixing mechanism enables the installation and position adjustment of the electricity meter. The locking mechanism uses a combination lock and a mechanical lock cylinder to form a double lock, preventing unauthorized disassembly, tampering with internal components or electricity theft. The support and reinforcement mechanism provides an extra layer of protection for the electricity meter, blocking rainwater and dust from entering and draining any water that seeps into the first layer of protection, keeping the inside of the meter dry.
[0020] 2. The adjusting nut is threadedly connected to the bolt on the back of the meter casing. By rotating the adjusting nut, the distance between the bracket plate and the meter casing can be adjusted, allowing for fine-tuning of the height or angle of the meter's installation position. The bracket plate, as the main support structure of the fixing mechanism, is fixedly connected to the external mounting surface through the mounting holes on the plate.

[0025] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0026] This application discloses a high-protection single-phase energy meter. (Refer to...) Figure 1-3The cover plate on one side of the watch body shell 1 is detachable for easy inspection and maintenance. A first groove 14 is provided at the other contact points of the cover plate on the watch body shell 1, and a first rubber gasket 15 is installed inside the first groove 4. The first rubber gasket 15 has good elasticity and sealing performance. When the cover plate is installed, it fills the gaps by squeezing and deforming, achieving a preliminary seal on the watch body shell and preventing rainwater, dust, and other external impurities from entering. A fixing mechanism 2 is provided on the back of the watch body shell 1. The fixing mechanism 2 includes multiple support plates 21 and adjusting nuts 22. Bolts 11 are fixedly connected to the watch body shell 1 at the four corners of the back of the watch body shell 1. The adjusting nuts 22 are rotatably connected to the support plates 21. The bracket plate 21 is connected to the bolts 11 at the four corners of the meter body shell, forming a threaded connection. The plate surface of the bracket plate 21 has multiple mounting holes 211 for fixing to the external mounting surface. One side of the adjusting nut 22 has a threaded hole with a locking bolt 23 inside. By rotating the adjusting nut 22, the distance between the bracket plate 21 and the meter body shell 2 can be adjusted, so as to make fine adjustments to the height or angle of the meter installation position to adapt to different installation environments. After adjusting to the appropriate position, tighten the locking bolt 23 so that it fits tightly against the bolt 11, restricting the rotation of the adjusting nut 22 and preventing the adjusting nut 22 from loosening due to vibration or other factors, thus ensuring that the meter is installed stably. A locking mechanism 3 is located at the front of the watch case. The locking mechanism 3 includes a combination lock 31 and a latch 32. One side of the latch 32 is connected to the watch case 1 via a hinge, allowing it to rotate and open around the hinge. The combination lock 31 is fixedly connected to the watch case 1, and its electronic lock cylinder is detachably connected to the other end of the latch 32. At the same time, a mechanical lock cylinder 33 is located on one side of the combination lock 31. The mechanical lock cylinder 33 is equipped with a corresponding key, and the connection position between the mechanical lock cylinder 33 and the latch 32 is the same as the connection position between the electronic lock cylinder and the latch 32. Under normal circumstances, when the watch case 1 and the locking mechanism 3 are connected, the correct password needs to be entered to unlock the electronic lock cylinder, which will rotate and open the latch 32, thereby opening the detachable cover. When the combination lock 31 malfunctions or fails, the matching key can be inserted into the mechanical lock cylinder 33 to unlock the latch 32 through the mechanical structure. This dual locking method effectively prevents unauthorized disassembly, tampering with internal components, or electricity theft. Next, let's look at the support and reinforcement mechanism 4 on the watch body shell. The support and reinforcement mechanism 4 includes a protective layer 41 and a pressure regulating valve 42. A slightly inclined V-shaped support plate 43 is provided on the upper inner layer of the watch body shell 1. The V-shaped support plate 43 is fixedly connected to the inner wall of the watch body shell 1. The space formed between the upper side of the V-shaped support plate 43 and the top of the watch body shell 1 is the protective layer 41. A second groove 431 is provided at the outer side of the V-shaped support plate 43 where it contacts the transparent cover plate 13. A second rubber pad 432 is installed inside the second groove 431. Pressure regulating valves 42 are provided on both sides of the watch body shell 1 at the position of the protective layer 41. Anti-climb spikes 12 are evenly distributed on the top surface of the meter housing 1. The anti-climb spikes 12 are fixedly connected to the top surface of the meter housing 1. The cover plate is set as a transparent cover plate 13 at the position of the meter display value. The transparent cover plate 13 is fixedly connected to other cover plate parts. The operator can clearly read the meter data through the transparent cover plate 13 without opening the cover plate, thus maintaining the normal operation and protection performance of the electricity meter.
[0027] The working principle of a high-protection single-phase energy meter in this application is as follows: The distance between the bracket plate 21 and the meter housing 1 can be adjusted by rotating the adjusting nut 22 to achieve fine adjustment of the height or angle of the energy meter installation position to adapt to different installation environments. After adjusting to the appropriate position, tighten the locking bolt 23 to make it tightly abut against the bolt 11, restricting the rotation of the adjusting nut 22 and preventing the adjusting nut 22 from loosening due to vibration or other factors, thus ensuring the energy meter is installed stably. Under normal circumstances, the meter housing 1 and the locking mechanism 3 require the correct password to be entered, the electronic lock cylinder to unlock, and the buckle 32 to rotate and open, thereby opening the detachable cover. When the password lock 31 malfunctions or fails, the matching key can be inserted into the mechanical lock cylinder 33, and the buckle 32 can be unlocked through the mechanical structure. The double locking method effectively prevents illegal disassembly, tampering with internal components or electricity theft.
[0028] The protective layer 41 of the support and reinforcement mechanism 4 utilizes the slightly tilted design of the V-shaped support plate 43 to guide rainwater down the outer wall of the watch body shell 1, reducing the possibility of rainwater seeping into the watch body. At the same time, it blocks dust, debris, etc. from entering the core component area. The second rubber pad 432 further strengthens the seal between the V-shaped support plate 43 and the cover plate, preventing rainwater and dust from entering through the connection. When there is water accumulation in the protective layer 41, the air pressure regulating valve 42 automatically drains the water from the watch body shell 1. Due to its one-way conduction characteristic, it can prevent external rainwater and debris from entering in reverse, keeping the inside of the watch body dry. The sharp anti-climb spikes 12 prevent birds from landing here, avoiding birds pecking at the watch body shell 1. At the same time, it can also prevent people from placing foreign objects, ensuring the structural integrity of the watch body shell 1 and internal components. The transparent cover plate 13 has the same protective performance as other cover plate parts, protecting the display screen or dial from the influence of the external environment. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
