Description

Technical Field

[0001] The utility model relates to the technical field of transformer protection, in particular to an outdoor transformer anti-collision device. Background Art

[0002] An outdoor transformer refers to a transformer installed outdoors, such as on the side of overhead lines, in distribution boxes, etc. It can withstand outdoor climatic conditions and ensure stable operation in various harsh environments. The working principle of an outdoor transformer is the same as that of an indoor transformer. It mainly relies on the principle of mutual inductance to achieve conversion of different voltages. Its iron core serves as a medium for energy transmission, transferring energy from one coil to another coil, while isolating the circuit to reduce the risk of current interruption.

[0003] The outdoor transformer anti-collision device is mainly a protective device designed to prevent the transformer from being accidentally impacted. This device is usually made of strong and durable materials, such as steel or special alloys, to withstand potential impact forces and ensure that the transformer can remain intact when subjected to external impacts, avoiding damage or failure caused by impact, thereby ensuring the stable operation of the power system.

[0004] The patent with publication number CN219226012U currently discloses an outdoor transformer anti-collision device, including a transformer, a mounting seat, a support column, an anti-collision inner cylinder, a support bottom plate and an anti-collision baffle, wherein the support column is fixedly connected to both sides of the mounting seat, the transformer is fixed to the surface of the mounting seat with bolts, the anti-collision baffle is arranged around the mounting seat, the anti-collision inner cylinder is sleeved on the bottom of the support column, the anti-collision outer cylinder is sleeved on the anti-collision inner cylinder, a plurality of buffer springs are arranged between the anti-collision outer cylinder and the anti-collision inner cylinder, the support bottom plate is arranged directly below the mounting seat, and the support bottom plate includes a plurality of fixing pins and support rods; although the above device solves the problem of pedestrians colliding with the bottom of the transformer and the mounting seat.

[0005] However, the above technical solution still has the following problems:

[0006] The anti-collision device is not connected to the wires above the outdoor transformer, which may cause the wire connections to be easily impacted by external forces, thereby increasing the risk of wire damage or breakage. These external factors may cause the wire connections to loosen, break or short-circuit, thereby affecting the normal operation of the transformer and may even cause failure of the entire power system. The wire connections are key nodes for current transmission and may also cause electrical failures such as overheating, sparks and even fires, posing safety hazards to personnel and equipment. Frequent wire connection failures require more manpower, material and financial resources for maintenance, increasing the company's operating costs. Utility Model Content

[0011] Furthermore, fixing strips are fixedly connected to both ends of the anti-collision shell, the bottom of the fixing strip is fitted and connected to the top of the transformer body, and the fixing strip and the transformer body are fixedly connected by external bolts.

[0012] Furthermore, buckle grooves are provided on both sides of the anti-collision shell, the bottom of the buckle grooves is connected to the inside of the anti-collision shell, and a shielding shell is installed on the outside of the buckle grooves of the anti-collision shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figures 1 to 7 As shown, an outdoor transformer anti-collision device includes a transformer body 1 and a wire connection end 101 connected to the top of the transformer body 1, an anti-collision shell 2 is installed on the top of the transformer body 1, the anti-collision shell 2 covers the wire connection end 101, heat dissipation nets 6 are provided on both sides of the anti-collision shell 2, the heat dissipation net 6 is connected to the inside of the anti-collision shell 2, buffer mechanisms 4 are provided on both sides of the anti-collision shell 2, the buffer mechanism 4 covers the heat dissipation net 6, and a connecting plate 3 is provided on the top of the anti-collision shell 2.

[0025] like Figure 1 As shown, an outdoor transformer anti-collision device in the utility model is similar in structure to the existing outdoor transformer anti-collision device, such as the outdoor transformer anti-collision device disclosed in the patent publication number CN219226012U. The main improvement of the utility model is to reduce the occurrence of electrical faults and avoid downtime and increased maintenance costs caused by faults. Figures 1 to 7As shown, when an outdoor transformer anti-collision device in the utility model is in use, the transformer body 1 is the core part of the entire device, which is responsible for the conversion and transmission of electric energy. The wire connection terminal 101 is located at the top of the transformer body 1, which is used to connect the wires to ensure that the electric energy can be smoothly transmitted to other devices or systems. The main function of the anti-collision shell 2 is to protect the transformer body 1 and the wire connection terminal 101 on the top from collision and impact of external objects. Heat dissipation nets 6 are provided on both sides of the anti-collision shell 2, which not only ensures that the transformer body 1 can dissipate heat normally during operation to prevent overheating, but also maintains air circulation inside the anti-collision shell 2. The buffer mechanism 4 has the main function of reducing the damage to the transformer body 1 caused by the impact force through the buffering effect when a collision occurs. The connecting plate 3 is located on the top of the anti-collision shell 2 for easy removal. During the installation process, if it is necessary to adjust the position or number of wires passing through the anti-collision shell 2, the connecting plate 3 can be easily removed for cutting.

[0026] like Figures 1 to 3 As shown, a slot 201 is provided on the top of the anti-collision shell 2, and a wire passage 202 connected to the inside of the anti-collision shell 2 is provided at the bottom of the slot 201. One side of the connecting plate 3 is fitted and connected to the bottom of the slot 201, and one end of the connecting plate 3 is slidably connected to the inner wall of the wire passage 202, and the connecting plate 3 and the anti-collision shell 2 are fixedly connected by external bolts.

[0027] Specifically, through this arrangement, the slot 201 is located at the top of the anti-collision shell 2, which provides a location for the connecting plate 3 to be installed and fixed. Through the slot 201, the connecting plate 3 can be firmly connected to the anti-collision shell 2, ensuring the stability and reliability of the entire device. The bottom of the slot 201 is designed with a wire passing channel 202, which allows the wires to easily pass through the anti-collision shell 2 without affecting the overall structure of the device. One end of the connecting plate 3 is slidably connected to the inner wall of the wire passing channel 202, which allows the connecting plate 3 to be easily moved in the wire passing channel 202 during installation and removal, facilitating the adjustment and cutting of the wires. The connecting plate 3 and the anti-collision shell 2 are fixedly connected by external bolts, which can ensure the firmness between the connecting plate 3 and the anti-collision shell 2.

[0028] like Figures 4 to 5 As shown, the buffer mechanism 4 includes a cylindrical shell 401, a spring 402, a connecting column 403 and a protective plate 8. The cylindrical shell 401 is fixedly connected to the outside of the anti-collision shell 2, the spring 402 is fixedly connected to the bottom of the cylindrical shell 401, the other end of the spring 402 is fixedly connected to the connecting column 403, and the other end of the connecting column 403 is fixedly connected to the protective plate 8.

[0029] Specifically, through this arrangement, the cylindrical shell 401 is fixedly connected to the outside of the anti-collision shell 2 to form a protective shell, which is not only the main structure of the buffer mechanism 4, but also carries other buffer components. The internal space of the cylindrical shell 401 provides an installation position for the spring 402 and the connecting column 403. At the same time, its sturdy structure can effectively disperse and absorb impact force. The connecting column 403 connects the spring 402 and the protective plate 8. When the spring 402 is compressed, the connecting column 403 can transfer the deformation force of the spring 402 to the protective plate 8, so that the protective plate 8 can fit tightly on the anti-collision shell 2, further enhancing the buffering effect.

[0030] like Figure 3 to Figure 4 As shown, fixing bars 7 are fixedly connected to both ends of the anti-collision shell 2, the bottom of the fixing bar 7 is fitted and connected to the top of the transformer body 1, and the fixing bar 7 and the transformer body 1 are fixedly connected by external bolts.

[0031] Specifically, by setting up this arrangement, the bottom of the fixing strip 7 is fitted and connected with the top of the transformer body 1, thereby ensuring close contact between the anti-collision shell 2 and the transformer body 1, reducing displacement or loosening caused by vibration or external impact, and the fixed connection through external bolts further enhances the stability of the connection, so that the anti-collision shell 2 can be stably fixed on the transformer body 1. The fixed connection is performed through external bolts. When the anti-collision shell 2 needs to be maintained or replaced, the fixing strip 7 and the bolts can be easily removed and re-fixed after completing the relevant operations.

[0032] like Figure 6 to Figure 7 As shown, buckle grooves 203 are provided on both sides of the anti-collision shell 2 , the bottom of the buckle grooves 203 is connected to the inside of the anti-collision shell 2 , and a shielding shell 5 is installed on the outside of the buckle grooves 203 of the anti-collision shell 2 .

[0033] Specifically, by setting the bottom of the buckle groove 203 to be connected with the inside of the anti-collision shell 2, this assists the heat dissipation net 6 in ventilating and dissipating the inside of the anti-collision shell 2, thereby preventing heat accumulation. The shielding shell 5 not only plays a protective role, but also the workers' hands can be buckled into the shielding shell 5 and the buckle groove 203, which provides convenience for the workers when moving the anti-collision shell 2.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
