Description

Technical Field

[0001] This invention belongs to the technical field of power distribution room protection equipment, and more specifically, it relates to a rodent barrier for power distribution rooms. Background Technology

[0002] Substations play a crucial role in power systems; however, rats often enter them, damaging electrical equipment. They can chew through wires, damage insulation, and cause serious faults such as short circuits and leakage, affecting power supply safety and stability. Traditional rat barriers in substations have many shortcomings. For example, ordinary rat barriers have a simple structure, being just a straight board, which may not be effective in stopping rats that are good at jumping or climbing. Moreover, they cannot drive rats away in time and are easily bumped by rats, causing the barriers to bend or be pushed aside. Summary of the Invention

[0003] The purpose of this invention is to provide a rodent barrier for power distribution rooms, which aims to solve the problems of existing rodent barriers having limited functionality and poor rodent-blocking effect.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a rodent barrier for a power distribution room is provided, comprising a barrier body, the barrier body comprising a vertical section and a bent section, the bent section being located at the upper end of the vertical section and bent towards the outside, the lower end of the vertical section being connected to a receiving platform, the receiving platform being located on the same side as the bent section, and an electric shock component being provided on the receiving platform.

[0005] In one possible implementation, the upper surface of the receiving platform is inclined downward from one side near the vertical section to the other side, and the middle part of the receiving platform has a receiving groove extending upward through the upper surface of the receiving platform. Multiple rotating rollers are arranged in the receiving groove along the inclined direction of the upper surface of the receiving platform, and the same belt is wound on the multiple rotating rollers. The electric shock component is arranged on the belt.

[0006] In one possible implementation, the electric shock component includes a plurality of first metal protrusions and a plurality of second metal protrusions, as well as a battery. The plurality of first metal protrusions and the plurality of second metal protrusions are arranged alternately on the transmission surface of the belt along the transmission direction of the belt. The plurality of first metal protrusions are connected in series by a first wire, and the plurality of second metal protrusions are connected in series by a second wire. The battery is disposed in the receiving groove, and the first wire and the second wire are respectively selectively connected to the positive or negative terminal of the battery.

[0007] In one possible implementation, the receiving slot is provided with a first metal paddle and a second metal paddle, the first metal paddle and the second metal paddle are located below the belt and are arranged back and forth along the transmission direction of the belt. The first metal paddle and the second metal paddle simultaneously and selectively abut against the first metal protrusion or the second metal protrusion. The first metal paddle and the second metal paddle are respectively connected to the positive and negative terminals of the battery through wires.

[0008] In one possible implementation, support bars are provided on the sidewalls of the receiving groove corresponding to both ends of the rotating roller shaft, and the ends of the multiple rotating rollers located on the same side are rotatably connected to the support bars on the same side.

[0009] In one possible implementation, the support bar has a first pivot at one end near the vertical section, and a first mounting hole is provided on the side wall of the receiving groove corresponding to the first pivot. The first pivot is inserted into the first mounting hole and rotatably connected to the first mounting hole. A torsion spring is provided between the first pivot and the first mounting hole. When the belt is compressed, the belt rotates downward so that the first metal protrusion and the second metal protrusion abut against the first metal lever or the second metal lever, respectively. When the belt is not compressed, the torsion spring is used to drive the support bar to rotate the belt upward so that the first metal protrusion and the second metal protrusion separate from the first metal lever or the second metal lever.

[0010] In one possible implementation, the support bar has a first pin at one end away from the vertical section, and a second mounting hole is provided on the side wall of the receiving groove corresponding to the first pin. The second mounting hole is an oblong hole, and the first pin is inserted into the second mounting hole. The second mounting hole is used to limit the movement range of the first pin.

[0011] In one possible implementation, the plate body includes a U-shaped frame and a movable plate. The U-shaped frame is used to fix it to the wall. The receiving platform is connected to the lower end of the U-shaped frame. The movable plate is located inside the U-shaped frame. The bottom of the movable plate is rotatably connected to the U-shaped frame. A limiting component is provided between the U-shaped frame and the movable plate. The limiting component is used to switch the movable plate between a vertical state and a horizontal state.

[0012] In one possible implementation, the U-shaped frame includes two columns, and the bottom of the opposite sidewalls of the two columns are provided with longitudinal grooves. The bottom of the movable plate is provided with a second pivot on the sidewall of the column, and the second pivot is inserted into the longitudinal groove on the same side and slidably connected to the longitudinal groove. The limiting component includes a second pin and a slot. The second pin is disposed on the upper end of the movable plate facing the sidewall of the column, and the slot is disposed on the sidewall of the column corresponding to the second pin. The slot extends upward through the column, and the second pin is inserted into the slot to limit the rotation of the movable plate.

[0013] In one possible implementation, when the movable plate is rotated to the side of the receiving platform and placed horizontally, the bent section on the movable plate abuts the ground, and there is a clearance space between the movable plate and the U-shaped frame to accommodate the receiving platform.

[0014] The beneficial effects of the rat barrier for power distribution rooms provided by this invention are as follows: Compared with the prior art, the rat barrier of this invention, by setting a bending section on the barrier body, can block the space for rats to jump upwards, preventing rats from crossing the barrier body. Furthermore, by setting a receiving platform at the lower end of the vertical section of the barrier body, and installing an electric shock component on the receiving platform, rats on the receiving platform can be shocked and driven away from the barrier body. The rat barrier for power distribution rooms provided by this invention effectively blocks rats that are good at jumping and effectively drives them away, preventing rats from colliding with the barrier body, thus improving the rat-blocking effect.

Therefore, they should not be construed as limitations on the present invention.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] Please see Figures 1 to 3 The present invention will now describe a rodent barrier for a power distribution room. The rodent barrier for a power distribution room includes a plate body 1, which includes a vertical section 101 and a bent section 102. The bent section 102 is located at the upper end of the vertical section 101 and bends outwards towards the power distribution room. A receiving platform 2 is connected to the lower end of the vertical section 101, located on the same side as the bent section 102. An electric shock component is provided on the receiving platform 2.

[0037] This invention provides a rodent barrier for power distribution rooms. Compared with existing technologies, by setting a bending section 102 on the barrier body 1, it can block the space for mice to jump upwards, preventing mice from crossing the barrier body 1. Furthermore, by setting a receiving platform 2 at the lower end of the vertical section 101 of the barrier body 1, and installing an electric shock component on the receiving platform 2, it can shock mice on the receiving platform 2, driving them away from the barrier body 1. This invention provides a rodent barrier for power distribution rooms that effectively blocks mice that are good at jumping and effectively drives them away, preventing them from colliding with the barrier body 1, thus improving the rodent-blocking effect.

[0038] In some embodiments, please refer to Figures 2 to 10 An assembly groove 103 is provided at the lower end of the vertical section 101 facing the power distribution room. The receiving platform 2 is inserted into the assembly groove 103 and fixed to the vertical section 101 by bolts. In this embodiment, the upper end face of the receiving platform 2 is an inclined surface, which is inclined downward from the side near the vertical section 101 to the other side. A receiving groove 201 is provided in the middle of the receiving platform 2, extending upward through the upper end face of the receiving platform 2. In this embodiment, the receiving groove 201 is centrally located along the length direction of the receiving platform 2, and the length of the receiving groove 201 is slightly less than the length of the receiving platform 2. The receiving groove 201 extends in the width direction at the end near the vertical section 101 and penetrates the end face of the receiving platform 2 near the vertical section 101. Multiple rotating rollers 4 are provided at the upper end of the receiving groove 201 along the inclined direction of the upper end face of the receiving platform 2. Multiple rotating rollers 4 are wound with the same belt 3, and an electric shock component is mounted on the belt 3. In this embodiment, the width of the belt 3 is approximately equal to the length of the receiving groove 201, and the upper surface of the belt 3 is basically flush with the upper end surface of the receiving platform 2. In application, if a mouse wants to hit the board body 1, it needs to pass through the receiving platform 2. When the mouse runs onto the receiving platform 2, it will step on the belt 3. As the mouse moves, the friction between the mouse and the belt 3 will drive the belt 3 to move in the opposite direction to the mouse's movement under the action of the rotating rollers 4, thus dissipating the impact force on the mouse and making it difficult for the mouse to approach the board body 1. In addition, when the mouse jumps onto the receiving platform 2 from the side, due to the inclined setting of the belt 3, the mouse will also be automatically transported away from the vertical section 101 on the belt 3 under the action of gravity, keeping the mouse away from the board body 1. Moreover, the electric shock component on the belt 3 can simultaneously shock the mouse, driving it away and preventing the mouse from lingering on the receiving platform 2 for a long time.

[0039] In some embodiments, please refer to Figure 3 , Figure 7 and Figure 8 The aforementioned plurality of rotating rollers 4 include a first roller body 41 and a second roller body 42. There are two first roller bodies 41, which are rotatably connected to both ends of the receiving groove 201 in the width direction. The belt 3 is wound around the two first roller bodies 41. There are a plurality of second roller bodies 42, which are rotatably connected in the receiving groove 201 and located between the two first roller bodies 41. In this embodiment, the two first roller bodies 41 divide the belt 3 into an upper belt 31 and a lower belt 32. The plurality of second roller bodies 42 are located between the upper belt 31 and the lower belt 32. In application, the plurality of second roller bodies 42 abut against the upper belt 31 to support the upper belt 31.

[0040] In some embodiments, please refer to Figure 3 , Figure 9 and Figure 10The aforementioned electric shock component includes multiple first metal protrusions 51 and multiple second metal protrusions 52, as well as a battery 6. In this embodiment, the multiple first metal protrusions 51 and multiple second metal protrusions 52 are arranged alternately on the transmission surface of the belt 3 along the transmission direction of the belt 3. The multiple first metal protrusions 51 are connected in series by a first wire 53, and the multiple second metal protrusions 52 are connected in series by a second wire 54. The battery 6 is disposed in the receiving groove 201. The first wire 53 and the second wire 54 are respectively connected to the positive or negative terminal of the battery 6. In this embodiment, the length of the first metal protrusions 51 and the second metal protrusions 52 is approximately equal to the width of the belt 3. In application, when a mouse jumps onto the belt 3, and its front and hind paws step on the first metal protrusions 51 and the second metal protrusions 52 respectively, current will pass through the mouse's body, causing an electric shock. In addition, by setting the first metal protrusions 51 and the second metal protrusions 52 on the belt 3, the friction of the transmission surface of the belt 3 is increased, making it easier for the mouse to drive the belt 3 when walking.

[0041] In some embodiments, please refer to Figure 3 and Figure 4 A first metal paddle 71 and a second metal paddle 72 are provided on the bottom side of the receiving groove 201 away from the vertical section 101. In this embodiment, the first metal paddle 71 and the second metal paddle 72 are elastic sheets. The first metal paddle 71 and the second metal paddle 72 are located below the belt 3 and are arranged back and forth along the transmission direction of the belt 3. The distance between the first metal sheet and the second metal sheet is approximately the same as the distance between the first metal protrusion 51 and the second metal protrusion 52 on the belt 3. In application, the first metal paddle 71 and the second metal paddle 72 simultaneously and selectively abut against the first metal protrusion 51 or the second metal protrusion 52. The first metal paddle 71 and the second metal paddle 72 are respectively connected to the positive and negative terminals of the storage battery 6 through wires.

[0042] In some embodiments, please refer to Figures 3 to 8Support bars 43 are provided on the side walls corresponding to both ends of the rotating roller 4 in the receiving groove 201. The ends of the multiple rotating rollers 4 located on the same side are rotatably connected to the support bars 43 on the same side. A receiving groove 202 is provided on the side wall of the receiving groove 201 corresponding to the side end of the rotating roller 4 shaft. The support bar 43 is installed in the receiving groove 202. Specifically, a first rotating shaft 431 is provided at one end of the support bar 43 near the vertical section 101. A first mounting hole 203 is provided on the side wall of the receiving groove 202 on the same side corresponding to the first rotating shaft 431. The first rotating shaft 431 is inserted into the first mounting hole 203 and rotatably connected to the first mounting hole 203. A torsion spring (not shown in the figure) is also provided between the first rotating shaft 431 and the first mounting hole 203. In application, when the mouse jumps onto the belt 3, the belt 3 is compressed and will rotate downward to compress the torsion spring, so that the first metal protrusion 51 and the second metal protrusion 52 abut against the first metal lever 71 or the second metal lever 72 respectively, thereby causing the first metal protrusion 51 to abut against the first metal lever 71 or the second metal lever 72. A metal protrusion 51 and a second metal protrusion 52 are connected to the battery 6 to shock a mouse. When the mouse jumps off the belt 3, the belt 3 is no longer compressed. The compressed torsion spring releases its elasticity, driving the support bar 43 to rotate the belt 3 upwards. This causes the first metal protrusion 51 and the second metal protrusion 52 to separate from the first metal lever 71 or the second metal lever 72, preventing the first metal protrusion 51 and the second metal protrusion 52 from being connected to the battery 6 for a long time. In practical applications, due to the influence of the external environment, some of the first metal protrusion 51 and the second metal protrusion 52 may form a connection. If the first metal protrusion 51 and the second metal protrusion 52 are electrically connected to the battery 6 for a long time, the first metal protrusion 51 and the second metal protrusion 52 will generate heat when current passes through them, which may easily burn the belt 3.

[0043] In this embodiment, please refer to Figures 3 to 8 A first pin 432 is provided at the end of the support bar 43 away from the vertical section 101. A second mounting hole 204 is provided on the side wall of the receiving groove 202 corresponding to the first pin 432. In this embodiment, the second mounting hole 204 is a longitudinally arranged elongated hole. In application, the first pin 432 is inserted into the second mounting hole 204. When the belt 3 is not subjected to external pressure, under the elastic force of the torsion spring, the first pin 432 abuts against the upper end of the second mounting hole 204, and the second mounting hole 204 restricts the second pin 122 from moving upward. When the belt 3 is subjected to external pressure, the support bar 43 drives the first pin 432 to move downward and abut against the lower end of the second mounting hole 204, so that the first metal protrusion 51 and the second metal bar on the belt 3 can press against the first metal pawl 71 or the second metal pawl 72. At this time, the second mounting hole 204 can restrict the downward movement of the first pin 432, so as to avoid the belt 3 moving downward too much when the belt 3 is subjected to excessive pressure, which would cause the first metal pawl 71 and the second metal pawl 72 to be crushed.

[0044] In some embodiments, please refer to Figure 1 ,、 Figures 11 to 14 The plate body 1 includes a U-shaped frame 11 and a movable plate 12. The U-shaped frame 11 is used to fix it to the wall. The receiving platform 2 is connected to the lower end of the U-shaped frame 11. The movable plate 12 is located inside the U-shaped frame 11. The bottom of the movable plate 12 is rotatably connected to the U-shaped frame 11. A limiting component is provided between the U-shaped frame 11 and the movable plate 12. The limiting component is used to switch the movable plate 12 between a vertical state and a horizontal state.

[0045] Specifically, the U-shaped frame 11 includes two uprights 111. The bottom of the opposite sidewalls of the two uprights 111 are provided with longitudinal grooves 112. A second rotating shaft 121 is provided on the bottom of the movable plate 12, corresponding to the sidewall of the uprights 111. The second rotating shaft 121 is inserted into the longitudinal groove 112 on the same side and is slidably connected to the longitudinal groove 112. The limiting component includes a second pin 122 and a slot 113. The second pin 122 is positioned on the sidewall of the movable plate 12 facing the uprights 111, and the slot 113 is used to lock the position. The slot 113 corresponds to the second pin 122 and is located on the side wall of the column 111. The slot 113 extends upward through the column 111. In application, when the movable plate 12 is in a vertical position, the second pin 122 is inserted into the slot 113, which restricts the rotation of the movable plate 12. When the movable plate 12 needs to be placed horizontally, simply pull the movable plate 12 upward to move the second pin 122 upward and disengage it from the slot 113, then rotate the movable plate 12 downward to place it horizontally. With the above configuration, the rodent barrier provided by this invention can be placed horizontally when workers or electrical equipment need to pass quickly, which is equivalent to reducing the blocking height of the plate body 1, thereby facilitating the quick passage of workers or electrical equipment between the two columns 111.

[0046] In addition, when the movable plate 12 is rotated to the side of the receiving platform 2 and placed horizontally, the bent section 102 on the movable plate 12 will abut against the ground, thereby providing a clearance space between the movable plate 12 and the U-shaped frame 11 to accommodate the receiving platform 2. This is equivalent to covering the receiving platform 2 with the movable plate 12, forming a protective shell for the receiving platform 2, thereby preventing workers and power distribution equipment from damaging the receiving platform 2 when entering or exiting.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
