[0002] Electrical equipment is a general term for various equipment in the power system. Common electrical equipment includes inverters, circuit breakers, and transformers. Electrical equipment often requires cables for electrical connection. In order to ensure the safety of electrical equipment, electrical equipment is often provided with a cable sheath. The cable can pass through the cable sheath to connect the components inside the electrical equipment with external equipment or power supply, which can achieve good waterproof and smoke-proof effects. However, the existing cable sheath and the corresponding position installation structure of the power equipment are simple, so that there is a good sealing effect between the cable and the cable sheath, but the sealing effect between the cable sheath and the power equipment is poor, which affects the normal use of the power equipment. At the same time, the existing cable sheath is generally a tower structure. When in use, the operator needs to cut the corresponding installation hole from the cable sheath according to the diameter of the cable, but the cable sheath lacks a gripping part, which may cause the operator's cutting process to be unstable, which in turn causes the cable sheath and the cable to have a poor sealing effect.

DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] One aspect of the present application provides a tower type cable protection sleeve, such as Figures 1 to 6As shown, one of the preferred embodiments includes a mounting plate 100 and at least one cable gland body 200. A sealing frame 101 is provided along the contour of the side of the mounting plate 100, and the sealing frame 101 is spaced apart from the edge of the mounting plate 100 so that when the mounting plate 100 and the power equipment are installed, the sealing frame 101 can form a first seal with the installation position. The mounting plate 100 is provided with a boss 106 protruding in the area surrounded by the sealing frame 101, and a recessed card slot 102 can be formed between the edge of the boss 106 and the sealing frame 101; so that when the mounting plate 100 is installed, the card slot 102 can be correspondingly fitted with the installation position of the power equipment to form a second seal. That is, the tower cable gland of the present application can form two seals through the corresponding fitting of the sealing frame 101 and the card slot 102 with the installation position on the power equipment, thereby ensuring the installation sealing of the mounting plate 100 and the power equipment. The cable sheath body 200 is mounted on the boss 106 , and cables and the like can pass through the cable sheath body 200 to connect components inside the power device, and ensure the sealing performance between the cable and the cable sheath body 200 .

[0029] It is understandable that the mounting plate 100 is generally a rectangular plate, and mounting holes 103 are provided at the four corners thereof; when installing the tower cable cover in the traditional way, the mounting plate 100 is generally a smooth structure, and the mounting plate 100 is attached to the same smooth contact position of the power equipment, and then the entire tower cable cover is fixed to the corresponding position of the power equipment by passing bolts through the mounting holes 103. However, considering the processing accuracy of the mounting plate 100 and the use environment of the power equipment, the smooth mounting structure is prone to poor sealing and water leakage.

[0030] Therefore, in the present application, a sealing frame 101 is provided with a convex shape along the contour direction at the edge of the mounting plate 100. The convex structure of the sealing frame 101 can be fitted with the sealing groove at the corresponding mounting position of the power equipment to construct a protective structure, thereby preventing rainwater and soot from entering. At the same time, the area surrounded by the sealing frame 101 is provided with a convex shape at an interval from the sealing frame 101 to form a convex platform 106, and a clamping groove 102 can be formed in the interval recessed area between the convex platform 106 and the sealing frame 101. When installing the mounting plate 100, a matching sealing block can be clamped in the clamping groove 102. The sealing block is made of a flexible material, such as rubber material. Thus, the mounting position of the mounting plate 100 and the power equipment can be secondarily sealed by the sealing block to further improve the sealing performance. Specifically, after the mounting plate 100 is installed, by tightening the bolts, the rubber sealing block fits with the mounting position of the power equipment, such as the bottom surface of the box body of the power equipment, and generates a certain extrusion to reduce the gap to form a seal. Correspondingly, after the rubber sealing block is installed in the clamping groove 102, it can be flush with the sealing frame 101 or slightly higher than the sealing frame 101 to ensure that the sealing block can stably fit with the bottom surface of the box body. Of course, it can also be that a sealing block is protrudingly provided on the bottom surface of the box body of the power equipment, and a seal is formed by the clamping and fitting of the sealing block and the clamping groove 102. Compared with the traditional method, the present application can effectively improve the installation sealing performance between the tower wire protection sleeve and the power equipment by forming a double-layer sealing structure.

[0031] In this embodiment, as Figures 1 to 5 shown, one side edge of the mounting plate 100 is aligned with one side edge of the power equipment, and both ends of this edge of the mounting plate 100 are in abutting fit with the corresponding positions of the power equipment through the step grooves 104.

[0032] It should be known that when installing the mounting plate 100, if the installation area opened on one side of the power equipment is located in the middle area, that is, when the installation area opened on one side of the power equipment is in a shape similar to a "mouth" shape, then when installing the mounting plate 100 in cooperation, it is necessary to align the four sides of the mounting plate 100 at the same time. However, the structural conditions on the power equipment will be blocked by the mounting plate 100, which is inconvenient for the installation of the mounting plate 100.

[0033] In this embodiment, one side edge of the mounting plate 100 is aligned with one side edge of the power equipment, that is, the installation area opened on one side of the power equipment is in a "U" shape. Then, when installing the mounting plate 100 and the power equipment, at least one side of the installation structure of the installation area of the power equipment can be observed by the operator, which is convenient for the installation of the mounting plate 100.

[0034] At the same time, if one side edge of the mounting plate 100 is directly aligned with one side edge of the power equipment, a straight seam will be produced. Taking the mounting plate 100 as an example, when the mounting plate 100 is installed on the bottom surface of the power equipment, one side edge of the mounting plate 100 will form a vertical seam with the bottom edge of the power equipment. In this way, when rainwater flows, the rainwater may flow into the interior of the power equipment along the vertical seam.

[0035] In this embodiment, step grooves 104 are provided at both ends of one side edge of the mounting plate 100, so that the installation joint between the mounting plate 100 and the power equipment can be changed from a straight structure to a zigzag structure. Taking the mounting plate 100 installed on the bottom surface of the power equipment as an example again, a horizontal joint will appear in the joint structure formed by one side edge of the mounting plate 100 and the bottom edge of the power equipment, and the horizontal joint can hinder the entry of rainwater, thereby improving the installation sealing of the mounting plate 100.

[0036] In this embodiment, Figure 2 , Figure 3 and Figure 5 As shown, the upper part of the step groove 104 is provided with an inclined surface 105, and the inclined surfaces 105 of the two step grooves 104 are inclined toward each other to form a guide structure for installing the mounting plate 100. Therefore, when installing the mounting plate 100 and the power equipment, the corresponding groove area opened on the power equipment can be easily aligned through the guide structure formed by the two inclined surfaces 105, and then the mounting plate 100 only needs to be fitted with the mounting end surface of the power equipment, that is, the positioning and alignment of the mounting plate 100 can be achieved by fitting the inclined surface 105 with the side surface of the corresponding groove area on the power equipment, and the corresponding sealing frame 101 and the card slot 102 on the mounting plate 100 can also be aligned with the corresponding area of ​​the power equipment, thereby improving the installation sealing of the mounting plate 100 and effectively reducing the installation difficulty of the mounting plate 100.

[0037] Specifically, Figure 3 As shown, for the inclined surface 105 to position the mounting plate 100 during the installation process, the inclined surface 105 only needs to have a certain inclination angle. For example, the angle between the inclined surface 105 and the plane perpendicular to the installation direction can be set as α, and the value of the angle α can be preferably 15° to 75°.

[0038] In this embodiment, the number of the cable sheath body 200 can be one or more. Generally speaking, the number of cables that need to be connected to the power equipment is large, so the number of the cable sheath body 200 is preferably multiple. For multiple cable sheath bodies 200, the sealing installation dimensions can be the same, that is, they correspond to the same type of cables, but the corresponding sealing installation dimensions can also be different, that is, there is at least one pair of cable sheath bodies 200 with different sealing installation dimensions, so as to achieve sealing matching of cables of different types or categories.

[0039] It should be known that the so-called sealing installation size of the cable sheath body 200 is the diameter size of the cable that the cable sheath body 200 can be sealed and sheathed with.

[0040] It is understandable that the specific number of the cable protection sleeve body 200 can be selected according to actual needs, for example Figure 1 and Figure 2 As shown, the number of the cable cover bodies 200 may be two, and the sealing dimensions corresponding to the two cable cover bodies 200 are different. Figures 4 to 6 As shown, there are four cable sheath bodies 200 , three of which have the same sealing dimensions, and the other cable sheath body 200 has a different sealing dimension.

[0041] In this embodiment, there are two main specific structures of the cable sheath body 200, one is a sealing cone 201, and the other is a sealing cylinder. According to the structural type of the cable sheath body 200, the present application mainly has the following three implementation methods for the specific configuration of multiple cable sheath bodies 200 arranged on the mounting plate 100.

[0042] Embodiment 1: The cable sheath body 200 only includes a sealing cone 201, for example Figure 1 and Figure 2 As shown, there are two wire sheath bodies 200. The sealing cone 201 is a multi-section structure, and each section corresponds to a different sealing installation size. The surface of the sealing cone 201 is provided with a corresponding sealing installation size mark in each section area to facilitate identification by the operator. For the sealing cone 201, since it is a multi-section structure and the boundary position of each section is obvious, when using the sealing cone 201, the operator can directly cut along the boundary position.

[0043] Embodiment 2: The cable sleeve body 200 only includes the second sealing tube 203, and the end of the second sealing tube 203 is provided with a hand-held portion 204, and the hand-held portion 204 is used to hold the second sealing tube 203 when cutting. Figure 5 and Figure 6 As shown, the second sealing cylinder 203 is a frustum structure with a smooth surface. When the second sealing cylinder 203 is used, the position to be cut by the second sealing cylinder 203 can be obtained according to the diameter of the cable to be sealed. The cutting position needs to be manually marked, so the end of the second sealing cylinder 203 needs to be held during cutting to ensure the stability of the cutting process. Therefore, a hand-held portion 204 can be integrally formed at the end of the second sealing cylinder 203. When the second sealing cylinder 203 is used, the operator can ensure the stability of the cutting process by holding the hand-held portion 204.

[0044] Embodiment 3: The cable sheath body 200 includes at least one sealing cone 201 and at least one second sealing cylinder 203. For example Figures 4 to 6 As shown, there are four sheath bodies 200, three of which are second sealing cylinders 203, and the remaining sheath body 200 is a sealing cone 201. Accordingly, the sealing cone 201 is a multi-section structure, and a hand-held portion 204 is provided at the end of the second sealing cylinder 203.

[0045] It should be known that the above three embodiments can all meet the requirements of this application, and the outer surface of the second sealing cylinder 203 is also provided with a mark showing the sealing installation size.

[0046] In this embodiment, Figure 1 , Figure 2 as well as Figures 4 to 6 As shown, the cable sleeve body 200 also includes a plurality of first sealing cylinders 202 in a conical structure. For the above-mentioned embodiment 1, the number of the first sealing cylinders 202 corresponds to the number of the sealing cones 201, the sealing cones 201 and the first sealing cylinders 202 are respectively arranged on opposite sides of the mounting plate 100, and the sealing cones 201 and the corresponding first sealing cylinders 202 are communicated with each other. For the above-mentioned embodiment 2, the number of the first sealing cylinders 202 corresponds to the number of the second sealing cylinders 203, the second sealing cylinders 203 and the first sealing cylinders 202 are respectively arranged on opposite sides of the mounting plate 100, and the second sealing cylinders 203 and the corresponding first sealing cylinders 202 are communicated with each other. For the above-mentioned embodiment 3, the sealing cones 201 and the second sealing cylinders 203 are arranged on one side of the mounting plate 100, the first sealing cylinder 202 is arranged on the other side of the mounting plate 100, and the first sealing cylinder 202 is correspondingly communicated with the sealing cones 201 and the second sealing cylinders 203. The first sealing cylinder 202 and the second sealing cylinder 203 , and the sealing cone 201 and the first sealing cylinder 202 can form a double sealing structure, thereby improving the sealing performance between the cable and the cable sheath body 200 .

[0047] Another aspect of the present application provides an electric power device, wherein a preferred embodiment includes a box and the tower-type cable protection sleeve, wherein the tower-type cable protection sleeve is installed on one side of the box. Preferably, the tower-type cable protection sleeve is installed at the bottom end of the box.
