Description

Technical Field

[0001] This utility model relates to the field of electrical equipment power supply safety technology, and in particular to a rodent-proof device and an electrical room. Background Technology

[0002] Electrical rooms typically house equipment such as cables, switch cabinets, terminal boxes, and mechanism boxes. To ensure the safe operation of electrical equipment and prevent small animals (such as rats) from entering the room and damaging the cables and equipment, rodent-proof devices need to be installed at the entrances and exits of the electrical room.

[0003] In related technologies, a structure is generally used where finished aluminum alloy rodent barriers are combined with bottom and side slots to prevent rodents at the entrance of the electrical room. However, when the entrance to the electrical room is long, a spliced ​​rodent barrier and slot structure is required, which not only involves more parts but also more gaps between the barrier and the floor and walls. Therefore, for electrical rooms used in desert areas or areas with high winds and sandstorms, a large amount of sand and dust can easily accumulate in the slots of the aforementioned rodent barrier structure, affecting the service life of the rodent barrier. Furthermore, wind and sand can enter the room through the gaps, causing damage to electrical equipment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one embodiment of this utility model proposes a rodent-blocking device.

The slot has a mounting cavity with a top opening and a first slot segment, a second slot segment, and a third slot segment surrounding the mounting cavity. The first slot segment, the second slot segment, and the third slot segment are integrally formed and arranged in a U-shape. The rodent-blocking plate is slidably fitted into the mounting cavity along the height direction, and the rodent-blocking plate can extend or retract relative to each of the first slot segment, the second slot segment, and the third slot segment. The rodent-blocking plate is used to block the mounting cavity.

[0008] According to the embodiment of this utility model, the rodent-blocking device is constructed by integrally forming a U-shaped slot structure from a first slot segment, a second slot segment, and a third slot segment. This reduces the number of parts and connection points in the slot, resulting in fewer installation gaps between the slot and the ground and wall. This ensures the dust-proof effect of the rodent-blocking plate that slides in the slot, while also reducing construction difficulty. Therefore, compared with related technologies, this utility model adopts an integral slot structure, which can effectively reduce the number of parts and the gaps between the slot and the ground and wall, resulting in better dust-proof effect and convenient construction.

[0034] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0035] like Figures 1 to 4As shown, an embodiment of the present invention provides a rodent-blocking device, comprising a slot 1 and a rodent-blocking plate 2. The slot 1 has a mounting cavity 11 with a top opening and a first groove segment 12, a second groove segment 13, and a third groove segment 14 forming the mounting cavity 11. The first groove segment 12, the second groove segment 13, and the third groove segment 14 are integrally formed and arranged in a U-shape. The rodent-blocking plate 2 is slidably fitted into the mounting cavity 11 along the height direction, and the rodent-blocking plate 2 can extend or retract relative to each of the first groove segment 12, the second groove segment 13, and the third groove segment 14. That is, the rodent-blocking plate 2 can be inserted into or removed from the mounting cavity 11 along the height direction, so that the rodent-blocking plate 2 is easy to install and remove within the slot 1. The rodent-blocking plate 2 is used to seal the mounting cavity 11.

[0036] According to the embodiment of the present invention, the rodent-blocking device is constructed by integrally forming a U-shaped slot 1 structure from the first slot segment 12, the second slot segment 13, and the third slot segment 14. This reduces the number of parts and connection points in the slot 1, resulting in fewer installation gaps between the slot 1 and the ground and wall. This ensures the dust-proof effect of the rodent-blocking plate 2 that slides in the slot 1, while also reducing construction difficulty. Therefore, compared with related technologies, the present invention adopts an integral slot 1 structure, which can effectively reduce the number of parts and the gaps between the slot 1 and the ground and wall, resulting in better dust-proof effect and convenient construction.

[0037] Specifically, slot 1 must meet fire safety regulations. The height direction can be vertical as shown in the diagram. The first slot segment 12, the second slot segment 13, and the third slot segment 14 are sequentially connected, and their channels are interconnected. The first slot segment 12 and the third slot segment 14 can be arranged alternately in the left-right direction as shown in the diagram and extend vertically. The second slot segment 13 can be located at the bottom of the first slot segment 12 and the third slot segment 14 and extend horizontally. The rodent-proof plate 2 can also be an integral structure, its overall dimensions matching the dimensions of the mounting cavity 11 of slot 1. The rodent-proof plate 2 can be a polyurethane sandwich panel.

[0038] It should be noted that the slot 1 used to install the rodent barrier 2 in related technologies is usually composed of three parts: the slots on the left and right sides and the bottom slot. The gap between the slot 1 and the rodent barrier 2 is large, which will cause a lot of sand to accumulate in windy and sandy areas, affecting the performance. However, the integrated U-shaped slot 1 structure in this utility model can effectively reduce the gap between the slot 1 and the rodent barrier 2.

[0039] like Figures 1 to 4 As shown, in some embodiments, at least one of the first groove segment 12 and the third groove segment 14 is provided with a first sealing strip 15. The first sealing strip 15 extends along the height direction and is sandwiched between either the first groove segment 12 or the third groove segment 14 and the rodent-proof plate 2 to seal the gap between the rodent-proof plate 2 and the mounting cavity 11, ensuring the sealing effect of the rodent-proof plate 2 on the mounting cavity 11 and improving the sealing performance of the rodent-proof device.

[0040] Preferably, both the first groove segment 12 and the third groove segment 14 are provided with a first sealing strip 15 to further ensure that there is no gap between the rodent-blocking plate 2 and the slot 1.

[0041] Specifically, taking the first groove segment 12 located at the left end of the second groove segment 13 in the figure and the third groove segment 14 located at the right end of the second groove segment 13 in the figure as an example, the first sealing strip 15 can seal the gap between the bottom of the first groove segment 12 and the left end of the rodent barrier 2, as well as the gap between the groove wall of the first groove segment 12 and the front and rear side walls of the rodent barrier 2. The first sealing strip 15 can seal the gap between the bottom of the third groove segment 14 and the right end of the rodent barrier 2, as well as the gap between the groove wall of the third groove segment 14 and the front and rear side walls of the rodent barrier 2, without affecting the normal disassembly and use of the rodent barrier 2.

[0042] like Figures 1 to 4 As shown, in some embodiments, the rodent-blocking device further includes a sand guide plate 3. The sand guide plate 3 is installed in the second groove section 13 and located below the rodent-blocking plate 2. The extension direction of the sand guide plate 3 is consistent with the extension direction of the second groove section 13. The top surface of the sand guide plate 3 is lower than the top surface of the second groove section 13 in the height direction. The top surface of the sand guide plate 3 and the groove of the second groove section 13 define a dust collection chamber 4 with a top opening. When the rodent-blocking plate 2 is removed during daily use or maintenance, the sand adhering to the rodent-blocking plate 2 and the sand accumulated at the contact gap between the rodent-blocking plate 2 and the slot 1 can fall and be collected into the dust collection chamber 4, which facilitates the subsequent treatment of the sand.

[0043] Specifically, the sand guide plate 3 can be fixed inside the second trough section 13. The specifications of the sand guide plate 3 can match the channel of the second trough section 13. The extension direction of the second trough section 13 can be the left-right direction as shown in the figure. The dust collection chamber 4 can extend in the left-right direction.

[0044] It should be noted that, taking the application of this rodent-blocking device in desert areas or areas with strong winds and sandstorms as an example, due to the influence of the application environment, a large amount of sand and dust will accumulate during the disassembly of the rodent-blocking plate 2, and the dust collection chamber 4 in this utility model can collect the accumulated sand and dust.

[0045] like Figure 3 As shown, in some embodiments, a second sealing strip 5 is provided at the bottom of the second groove segment 13. The second sealing strip 5 extends along the extension direction of the second groove segment 13 and is sandwiched between the second groove segment 13 and the sand guide plate 3 to seal the gap between the sand guide plate 3 and the second groove segment 13.

[0046] like Figure 3As shown, in some embodiments, the sand guide plate 3 has a first end and a second end opposite to each other along its length direction. The height of the top surface of the sand guide plate 3 gradually decreases from the middle position of the sand guide plate 3 toward at least one of the first end and the second end of the sand guide plate 3. That is, the top surface of the sand guide plate 3 has a slope so that the sand and dust falling into the dust collection chamber 4 can slide down and accumulate at the end of the sand guide plate 3, thereby facilitating the cleaning operation of the sand and dust.

[0047] Specifically, the first end of the sand guide plate 3 corresponds to the left end of the sand guide plate 3 in the figure. The second end of the sand guide plate 3 corresponds to the right end of the sand guide plate 3 in the figure. The height of the top surface of the sand guide plate 3 can gradually decrease from the middle position of the sand guide plate 3 toward the first end of the sand guide plate 3; or, the height of the top surface of the sand guide plate 3 can gradually decrease from the middle position of the sand guide plate 3 toward the second end of the sand guide plate 3; or, the height of the top surface of the sand guide plate 3 can gradually decrease from the middle position of the sand guide plate 3 toward each of the first and second ends of the sand guide plate 3, that is, the top surface of the sand guide plate 3 can include the aforementioned three structural forms.

[0048] Preferably, the height of the top surface of the sand guide plate 3 gradually decreases in the direction from the middle position of the sand guide plate 3 toward each of the first and second ends of the sand guide plate 3, so as to further facilitate the cleaning operation of sand and dust.

[0049] In some embodiments, the height of the top surface of the sand guide plate 3 gradually decreases along the direction from the first end of the sand guide plate 3 toward the second end (not shown in the figure), or the height of the top surface of the sand guide plate 3 gradually decreases along the direction from the second end of the sand guide plate 3 toward the first end (not shown in the figure), as long as it can achieve the collection and treatment of sand and dust, and there is no limitation here.

[0050] like Figures 1 to 3 As shown, in some embodiments, the second groove segment 13 has a first groove wall and a second groove wall opposite to each other along the thickness direction of the slot 1, and the thickness direction of the slot 1 is perpendicular to the height direction and the extension direction of the second groove segment 13.

[0051] The first and second tank walls are provided with a sand discharge port 131 that connects the dust collection chamber 4 to the external environment. The sand discharge port 131 is located at the lowest position on the top surface adjacent to the sand guide plate 3. The sand discharge port 131 allows the sand accumulated in the dust collection chamber 4 to be discharged from the slot 1, which further facilitates the sand handling operation, reduces the wear of sand on the rodent barrier plate 2, and ensures the service life of the rodent barrier plate 2.

[0052] Specifically, the thickness direction of slot 1 can be the front-to-back direction as shown in the figure. The first slot wall can correspond to the front slot wall in the figure. The second slot wall can correspond to the rear slot wall in the figure.

[0053] It should be noted that when the rodent barrier 2 is disassembled during daily use or maintenance, the sand and dust falling into the dust collection chamber 4 will accumulate along the slope of the sand guide plate 3 to the lowest position of the sand guide plate 3 and be discharged from the sand discharge port 131. In order to ensure the sand discharge effect in the dust collection chamber 4, after the rodent barrier 2 is disassembled, a brush can be used manually to help sweep the sand and dust out of the sand discharge port 131 to clean the dust collection chamber 4 regularly, thereby further improving the wind and sand prevention effect of the rodent barrier device.

[0054] like Figure 1 As shown, in some embodiments, the rodent-blocking device further includes a cover 6, which is detachably connected to the slot 1. The cover 6 is adapted to cover the sand discharge port 131 to prevent small animals (such as mice) from entering the slot 1 from the sand discharge port 131.

[0055] Specifically, the cover 6 is detachably installed on the outer wall of the first wall or the outer wall of the second wall of the second trough section 13 to cover the sand discharge port 131.

[0056] like Figure 1 As shown, in some embodiments, the rodent-blocking device further includes a sand-discharging plate 7, the sand-discharging plate 7 extending in the same direction as the second groove section 13, the sand-discharging plate 7 being detachably fitted into the dust collection chamber 4 and spaced apart above the sand guide plate 3 along the height direction, and the bottom surface of the rodent-blocking plate 2 being adapted to press against the top surface of the sand-discharging plate 7.

[0057] The sand discharge plate 7 is provided with multiple through holes 71. The multiple through holes 71 extend from the top surface to the bottom surface of the sand discharge plate 7. That is, the through holes 71 penetrate the sand discharge plate 7 along the thickness direction (i.e. the height direction) so that the through holes 71 can discharge sand and dust into the dust collection chamber 4.

[0058] Understandably, the sand-removing plate 7 can support and limit the installation of the rodent-blocking plate 2 in the second groove section 13, while also allowing sand and dust to fall into the dust collection chamber 4 through the through hole 71 for collection and treatment.

[0059] Specifically, multiple through holes 71 can be arranged in an array on the sand-removing plate 7.

[0060] An electrical room according to an embodiment of this utility model includes a room body, a room door, and a rodent-proof device (not shown in the figure). The room body has a door opening. The rodent-proof device is any of the rodent-proof devices described above. Both the rodent-proof device and the room door are fitted into the door opening. The slot 1 of the rodent-proof device is connected to the room body. The rodent-proof device is located closer to the interior side of the room body than the room door, that is, the rodent-proof device is located inside the room door. The exterior side of the room body, the room door, the rodent-proof device, and the interior side of the room body are arranged in sequence. The room door is movably connected to the room body and is used to block the door opening.

[0061] According to the embodiment of the present invention, the slot 1 in the rodent-proof device is designed as a U-shaped integrated structure to reduce the connection gap between the slot 1 and the ground and wall, and ensure the dustproof effect. Therefore, compared with related technologies, the electrical room using this rodent-proof device can effectively prevent dust from entering the room, reduce the damage to the cables and equipment in the room, and ensure the cleanliness of the room.

[0062] It should be noted that when it is necessary to inspect and repair the cables and equipment in the electrical room, the staff only need to open the room door and step over the rodent barrier 2 to enter and exit the room. When it is necessary to transport or replace equipment inside or outside the room, the rodent barrier 2 can be removed to facilitate the passage of equipment.

[0063] like Figure 4 As shown, in some embodiments, the electrical compartment further includes a third sealing strip 8, which is sandwiched between the bottom surface of the second groove segment 13 of the slot 1 and the ground to seal the gap between the rodent-proof device and the ground, ensuring the airtightness of the electrical compartment. The third sealing strip 8 can extend along the extension direction of the second groove segment 13, that is, the third sealing strip 8 extends along the left-right direction in the figure.

[0064] In some embodiments, the electrical compartment further includes a fourth sealing strip (not shown), which is sandwiched between the slot 1 and the wall of the compartment to seal the gap between the slot 1 and the wall of the compartment, further ensuring the airtightness of the electrical compartment. The fourth sealing strip may extend along the height direction.

[0065] It should be noted that the specific sealing materials of the first sealing strip 15, the second sealing strip 5, the third sealing strip 8, and the fourth sealing strip can be selected according to actual needs to ensure good sealing performance, and no restrictions are imposed here.

[0066] like Figure 1 As shown, in some embodiments, the first groove segment 12 and the second groove segment 13 of the slot 1 both have a first groove wall and a second groove wall that are opposite to each other along the thickness direction of the slot 1.

[0067] The electrical room also includes a first angle steel 91 and a second angle steel 92. The first angle steel 91 is pressed between the first groove wall and the wall of the room body, and the second angle steel 92 is pressed between the second groove wall and the wall of the room body. The first angle steel 91 and the second angle steel 92 are respectively located on both sides of the slot 1 along the thickness direction of the slot 1 and are both connected to the wall of the room body through locking parts 93, so as to limit the slot 1 in the door opening, realize the convenient installation of the slot 1 at the door opening, the construction operation is simple and the reliability is strong.

[0068] Specifically, both the first angle steel 91 and the second angle steel 92 extend along the height direction to further increase the contact area between each of the first angle steel 91 and the second angle steel 92 and the slot 1 and the wall of the chamber, so that the first angle steel 91 and the second angle steel 92 can reliably limit the slot 1 to the wall. Both the first angle steel 91 and the second angle steel 92 can be hot-rolled angle steel. The locking member 93 can be an expansion bolt. There can be multiple locking members 93, which are arranged at intervals along the extension direction of either the first angle steel 91 or the second angle steel 92 to ensure the fastening effect of the first angle steel 91 or the second angle steel 92 on the wall of the chamber.
