Description

Technical Field

[0001] The utility model relates to the technical field of resistor sheet protective covers for tank type lightning arresters, in particular to a resistor sheet spraying protective cover. Background Art

[0002] During the production and use of tank arrester resistors, the resistors need to be sprayed with electrodes to improve their electrical properties. However, during the spraying process, the sides of the resistors must be effectively protected to prevent the spraying material from penetrating into the non-working area of ​​the resistors, which may cause the performance of the resistors to deteriorate or be damaged. Therefore, a protective cover is required to cover and protect the non-spraying area of ​​the resistors when spraying the resistors.

[0003] Existing protective covers for spraying resistors have some shortcomings in design and use. First, these protective covers usually need to rely on bolt connections when installing. Bolting not only increases the complexity and time cost of the installation process, but also the tightness of the bolts directly affects the sealing and stability of the protective cover. If the bolts are not tightened correctly, the protective cover will leak or loosen, causing the spray material to penetrate into the non-working area of ​​the resistor, affecting the performance of the resistor. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of the present invention is to provide a protective cover for resistor spraying, which solves the problems raised in the above background.

[0006] (II) Technical solution

[0007] A protective cover for spraying a resistor sheet comprises a protective cover body, wherein the inner wall of the protective cover body is provided with a plurality of mounting grooves, and the inner walls of the plurality of mounting grooves are connected with a plurality of springs, one end of the plurality of springs is connected with a connecting block, and one end of the connecting block is connected with a clamping plate, the bottom end of the clamping plate is arc-shaped, and the outer surface of the clamping plate is wrapped with rubber, and a bottom ring is fixedly installed at the bottom end of the protective cover body.

[0008] Preferably, a ventilation plate is fixedly mounted on the inner wall of the top of the protective cover body, and the ventilation plate allows air to circulate, thereby effectively improving the heat dissipation performance of the resistor after spraying. During the spraying process, the resistor will heat up due to heat accumulation, and the design of the ventilation plate can accelerate the heat dissipation and prevent the resistor from overheating.

[0009] Preferably, a limiting groove is provided on the inner wall of the top end of the protective cover body, and a rotating plate is movably installed on the inner wall of the limiting groove, and a plurality of ventilation grooves are provided on the outer surface of the rotating plate. By movably installing the rotating plate in the limiting groove, the user can adjust the angle of the rotating plate as needed, thereby controlling the opening degree of the ventilation grooves, so that the heat dissipation performance is flexible, and the heat dissipation can be adjusted according to the actual temperature and working state of the resistor to achieve the best heat dissipation effect. When ventilation and heat dissipation are not required, the rotating plate can be rotated to the position of closing the ventilation grooves, so that a relatively sealed space is formed inside the protective cover, which effectively prevents the entry of external dust, impurities, etc., and keeps the resistor clean.

[0010] Preferably, the outer surface of the middle end of the rotating plate is connected to a connecting rod, and the top end of the connecting rod is connected to an operating rod. The rotating plate is connected to the operating rod through the connecting rod. The user can easily control the rotation of the rotating plate directly through the operating rod, thereby adjusting the ventilation effect, and the operation is more convenient and intuitive.

[0011] Preferably, the outer surface of the operating rod is serrated and wrapped with rubber. The serrated outer surface of the operating rod increases the friction between the hand and the operating rod, effectively preventing operational errors caused by hand slippage during rotation, and improving the accuracy and safety of operation. The rubber provides better grip comfort and feel, reducing discomfort to the hand caused by long-term operation.

[0012] Preferably, a rubber airbag is installed at the bottom end of the bottom ring. The rubber airbag has good elasticity and sealing properties. When installed at the bottom end of the bottom ring, it can fit the resistor more closely, effectively preventing the spray material from leaking from the bottom, and improving the sealing performance of the protective cover.

[0013] Preferably, the bottom end of the bottom ring is conical, and the conical design also increases the contact area between the bottom ring and the resistor sheet, thereby improving the stability of the protective cover and preventing it from shifting or falling off during the spraying process.

[0014] It can be seen from the above technical solutions that the present application has the following beneficial effects:

[0015] 1. The utility model opens multiple groups of installation grooves on the inner wall of the protective cover body, and installs a clamping plate connected to a spring and a connecting block. The outer surface of the clamping plate is wrapped with rubber material, which can not only increase the friction of clamping and prevent sliding, but also reduce the wear on the surface of the resistor and protect the resistor from damage, thereby achieving stable clamping of the resistor and simple installation and disassembly.

[0016] 2. The top inner wall of the protective cover of the utility model is designed with a ventilation plate, and the rotation of the rotating plate is controlled by rotating the operating lever to adjust the relative position of the ventilation slot and the filter hole of the ventilation plate to open and close the heat dissipation channel. This design allows the user to flexibly adjust the heat dissipation effect according to the actual temperature and working requirements of the resistor, ensuring that the resistor can quickly dissipate heat after spraying to avoid overheating affecting performance.

[0025] A protective cover for spraying a resistor comprises a protective cover body 1, wherein the inner wall of the protective cover body 1 is provided with a plurality of mounting grooves 111, and the inner walls of the plurality of mounting grooves 111 are all connected with a plurality of springs 912, one end of the plurality of springs 912 is connected with a connecting block 911, and one end of the connecting block 911 is connected with a clamping plate 9, the bottom end of the clamping plate 9 is arc-shaped, and the outer surface of the clamping plate 9 is wrapped with rubber, and a bottom ring 2 is fixedly installed at the bottom end of the protective cover body 1. A ventilation plate 4 is fixedly installed on the inner wall of the top end of the protective cover body 1, and the ventilation plate 4 allows air circulation, thereby effectively improving the heat dissipation performance of the resistor after spraying. During the spraying process, the resistor will heat up due to heat accumulation, and the design of the ventilation plate 4 can accelerate the heat dissipation and prevent the resistor from overheating.

[0026] The top inner wall of the protective cover body 1 is provided with a limit groove 112, and a rotating plate 3 is movably installed on the inner wall of the limit groove 112, and a plurality of ventilation grooves 7 are provided on the outer surface of the rotating plate 3. Through the movable installation of the rotating plate 3 in the limit groove 112, the user can adjust the angle of the rotating plate 3 as needed, thereby controlling the opening degree of the ventilation groove 7, so that the heat dissipation performance is flexible, and the heat dissipation can be adjusted according to the actual temperature and working state of the resistor to achieve the best heat dissipation effect. In the case of no need for ventilation and heat dissipation, the rotating plate 3 can be rotated to the position of closing the ventilation groove 7, so that a relatively sealed space is formed inside the protective cover, effectively preventing the entry of external dust, impurities, etc., and keeping the resistor clean. The middle outer surface of the rotating plate 3 is connected with a connecting rod 5, and the top of the connecting rod 5 is connected with an operating rod 6. The rotating plate 3 is connected to the operating rod 6 through the connecting rod 5, and the user can easily control the rotation of the rotating plate 3 directly through the operating rod 6, thereby adjusting the ventilation effect, and the operation is more convenient and intuitive.

[0027] The outer surface of the operating rod 6 is serrated, and the outer surface of the operating rod 6 is wrapped with rubber. The serrated outer surface of the operating rod 6 increases the friction between the hand and the operating rod, effectively preventing operational errors caused by hand slippage during rotation, and improving the accuracy and safety of operation. The rubber provides better grip comfort and feel, reducing the discomfort of the hand caused by long-term operation.

[0028] A rubber airbag 8 is installed at the bottom end of the bottom ring 2. The rubber airbag 8 has good elasticity and sealing performance. When installed at the bottom end of the bottom ring 2, it can fit the resistor more closely, effectively prevent the spraying material from leaking from the bottom, and improve the sealing performance of the protective cover. The bottom end of the bottom ring 2 is conical. The conical design also increases the contact area between the bottom ring 2 and the resistor, improves the stability of the protective cover, and prevents displacement or falling off during the spraying process.

[0029] Working principle: First, during the spraying process of the resistor, the protective cover body 1 is directly clamped on the resistor. The multiple groups of mounting grooves 111 provided on the inner wall of the protective cover body 1 are provided with a clamping plate 9 connected to a spring 912 and a connecting block 911. Due to the elastic effect of the spring 912, the connecting block 911 and the clamping plate 9 can freely expand and contract in the mounting groove 111. The bottom end of the clamping plate 9 is designed to be arc-shaped, and its outer surface is wrapped with rubber. This design can ensure that the clamping plate 9 fits tightly and evenly on the outer surface of the resistor to achieve a stable clamping effect.

[0030] When the protective cover body 1 is correctly installed on the resistor, the spraying work can start. Due to the clamping effect of the clamping plate 9, the protective cover body 1 can effectively cover and protect the non-spraying area of ​​the resistor to prevent the spraying material from penetrating.

[0031] After the spraying work is completed, in order to accelerate the heat dissipation of the resistor, a ventilation plate 4 is designed on the inner wall of the top of the protective cover body 1. In addition, by rotating the operating rod 6, the connecting rod 5 and the rotating plate 3 can be driven to rotate. The outer surface of the rotating plate 3 is also provided with multiple sets of ventilation grooves 7. When the rotating plate 3 rotates to a certain angle, the ventilation grooves 7 and the filter holes on the outer surface of the ventilation plate 4 are misaligned with each other, thereby opening the heat dissipation channel, allowing external air to enter the protective cover through the filter holes, and accelerating the heat dissipation speed of the resistor.

[0032] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
