Description

Technical Field

[0001] The utility model relates to the technical field of identification plate installation and fixing, in particular to an identification plate fixing device for electric power facilities. Background Art

[0002] Power facilities are the general term for all power generation, substation, transmission and power supply facilities. All power generation facilities, substation facilities, transmission facilities within the power plant (station) and substation area, as well as power supply, transmission facilities and auxiliary facilities outside the plant (station) and substation area. In order to improve the safety of power facility use, power personnel will fix identification signs on the surface of power facilities or in the use area.

[0003] In the prior art, when installing the signboard, the signboard is mostly fixed on the bracket structure for installation, and then fixed by a locking member; for example, Chinese patent CN214847575U disclosed on November 23, 2021, relates to a power facility signboard fixing device, which fixes the signboard by the clamping action between the upper spring plate and the lower base, and when installing the signboard, it is necessary to first pull up the upper spring plate that can move up and down, and then insert the signboard and adjust it to the vertical direction. After releasing the spring plate, the signboard is finally fixed between the spring plate and the base under the action of the elastic force.

[0004] However, in the process of installing the signboard, the bracket structure is not convenient for assisting the positioning of the signboard in the prior art. The signboard is prone to sliding sideways or tipping over during assembly and later disassembly of the bracket. For example, during maintenance, the bracket structure needs to be disassembled. At this time, the bracket structure cannot maintain its original posture (tilted or flipped), causing the signboard fixed inside it to slide sideways; or, for example, during installation, the bracket structure has not yet completed the fixation of the signboard. At this time, one end of the signboard (usually the bottom end) is first placed in the bottom of the bracket structure, and then the other end of the signboard (upper end) is placed against the top of the bracket structure. However, in the process of pulling the upper part of the bracket structure to move down and fix the signboard, since the signboard has not been fixed, the upper end of the signboard may tip forward (under the action of gravity) and detach. This is more obvious when the bracket structure has a downward tilt angle, unless the operator uses other methods (such as hands) to press the signboard to temporarily apply fixing pressure.

[0005] These situations will affect the efficiency of the installation process and subsequent maintenance. Utility Model Content

[0006] The utility model aims to provide a fixing device for a signboard of an electric power facility, which can assist in fixing the signboard, and the signboard will not slide sideways or fall out of the fixing device during installation and disassembly and maintenance;

[0007] The utility model provides a device for fixing a sign of an electric facility, comprising a limit frame, wherein a bottom plate for carrying the sign is provided at the bottom of the limit frame, a top plate which can be close to or away from the bottom plate is provided at the top of the limit frame, and an assembly plate is provided at the back of the limit frame; an assembly groove is provided in the middle of the assembly plate, and a permanent magnet is embedded and fixed in the assembly groove; a plurality of friction plates are provided on the assembly plate, and the plurality of friction plates are arranged around the four sides of the assembly groove.

[0008] Furthermore, the outer end of the permanent magnet is flush with the surface of the mounting plate.

[0009] Furthermore, the friction plate is a rubber plate with anti-slip grooves on the surface.

[0010] Furthermore, a slot is provided on the inner side of the bottom plate, and the bottom end of the identification plate is placed in the slot.

[0011] Furthermore, the bottom end of the top plate is connected to a rubber seat, and a buffer hole is provided in the rubber seat.

[0012] Furthermore, a clamping plate is connected to the bottom end of the rubber seat, and a clamping groove is formed on the bottom surface of the clamping plate.

[0013] Furthermore, guide grooves are provided on both sides of the top end of the limit frame, and guide posts are provided on both sides of the bottom end of the top plate, and the guide posts are slidably inserted in the guide grooves.

[0014] Furthermore, a return spring is sleeved on the outer side of the guide column, and the upper and lower ends of the return spring are respectively connected to the top plate and the limit frame.

[0015] Furthermore, it also includes a back plate, and mounting ear plates are provided on both sides of the back plate for fixing at the installation position.

[0016] Furthermore, the limit frame is fixed on the surface of the back plate, and a boss structure facing the back plate is provided in the middle of the top plate; a positioning groove is provided at the top of the back plate, and a positioning hole is opened on the boss structure of the top plate, and the locking piece is inserted into the positioning groove through the positioning hole.

[0017] The technical solution of the utility model is to set a permanent magnet in the limit frame and set a friction plate around the permanent magnet. During the installation of the identification plate, the operator directly sticks the identification plate on the assembly plate, and applies an adsorption and fixing force through the permanent magnet to prevent it from tipping over, and increases the friction force through the friction plates around it to prevent the identification plate from rotating or sliding, thereby forming a temporary auxiliary fixation for the identification plate; then the top plate is controlled to move down and the bottom plate is used to clamp the identification plate together to fix it, so that the identification plate is completely fixed. During the inspection and disassembly process, even if the top plate or the entire limit frame is removed, the identification plate will not easily fall off due to the adsorption force of the permanent magnet and the friction force of the friction plate. Therefore, the device can improve the efficiency of the installation process and subsequent inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1

[0031] like Figure 1-Figure 6 As shown, the utility model provides a device for fixing a sign of an electric facility, comprising a limit frame 2, a bottom plate 203 for carrying the sign is provided at the bottom of the limit frame 2, a top plate 8 which can be close to or away from the bottom plate 203 is provided at the top of the limit frame 2, and an assembly plate 204 is provided at the back of the limit frame 2; an assembly groove 201 is provided in the middle of the assembly plate 204, and a permanent magnet 3 is embedded and fixed in the assembly groove 201; a plurality of friction plates 4 are provided on the assembly plate 204, and the plurality of friction plates 4 are arranged around the assembly groove 201.

[0032] Specifically, the bottom plate 203 is connected to the bottom front side of the assembly plate 204, and the left and right front sides of the assembly plate 204 are also connected to the side plates 205, and the bottom ends of the two side plates 205 are connected to the bottom plate 203, thereby forming a limit frame 2. The top plate 8 is an adjustable structure. According to the height of the sign, the distance between the top plate 8 and the bottom plate 203 is adjusted to clamp signboards of different sizes. The signboard is clamped between the top plate 8 and the bottom plate 203 to achieve complete fixation.

[0033] Since the distance between the top plate 8 and the bottom plate 203 needs to be adjusted according to the size of the sign, in the present device, at the beginning, the top plate 8 needs to be pulled up first to keep it away from the bottom plate 203, then the sign is placed on the bottom plate 203, and then the top plate 8 is pulled down to clamp the sign and fix the position of the top plate 8. When the sign is placed on the bottom plate 203 and the top plate 8 has not been pulled down or is being pulled down, the conventional prior art may cause the sign to tip forward or slip to the sides, especially when the fixing bracket itself is installed at an angle.

[0034] In the present device, after the identification plate is placed on the bottom plate 203, the identification plate only needs to be placed against the assembly plate 204, and the permanent magnet 3 will attract the identification plate, so the identification plate will not fall forward; and the surrounding of the identification plate adsorption area is also in contact with the friction plate 4, and the adsorption force provides static friction, so the identification plate will not slip to the sides, so the identification plate is temporarily fixed. Then, it is only necessary to continue to pull down the top plate 8, so that the top plate 8 and the bottom plate 203 completely clamp the identification plate, and the identification plate can be completely fixed.

[0035] During the disassembly and maintenance process, the identification plate will not fall off easily due to the effect of the permanent magnet 3 and the friction plate 4. Thus, the device can improve the efficiency of the installation process and the later maintenance.

[0036] Example 2

[0037] The outer end of the permanent magnet 3 is flush with the surface of the mounting plate 204. The friction plate 4 is a rubber plate with anti-skid patterns on the surface.

[0038] Specifically, the end face of the permanent magnet 3 can be slightly protruding from the plane of the mounting plate 204, flush with the plane of the mounting plate 204, or slightly recessed from the plane of the mounting plate 204, and can exert magnetic attraction on the identification plate, but needs to be recessed relative to the plane of the friction plate 4 so that the identification plate can contact the friction plate 4. The mounting groove 201 and the permanent magnet 3 are circular, and the rubber plate is four elliptical pads, which are equally spaced around the permanent magnet 3, and the friction effect is improved by the anti-slip pattern.

[0039] Example 3

[0040] The bottom plate 203 has a slot 5 inside, and the bottom end of the identification plate is placed in the slot 5. The bottom end of the top plate 8 is connected to a rubber seat 9, and a buffer hole is provided in the rubber seat 9. The bottom end of the rubber seat 9 is connected to a clamping plate 10, and a clamping groove 11 is provided on the bottom surface of the clamping plate 10.

[0041] Specifically, the slot 5 on the bottom plate 203 and the clamping groove 11 on the clamping plate 10 are arranged opposite to each other and are used to clamp the upper and lower ends of the identification plate. The rubber seat 9 is elastic and is used to provide buffering, such as compensation for thermal expansion and contraction of the identification plate. The rubber seat 9 is hollow inside to form a buffer hole to improve the deformation buffering effect.

[0042] Example 4

[0043] The top of the limit frame 2 is provided with guide grooves 202 on both sides, and the bottom of the top plate 8 is provided with guide posts 6 on both sides, and the guide posts 6 are slidably inserted in the guide grooves 202. The outer side of the guide post 6 is sleeved with a return spring 7, and the upper and lower ends of the return spring 7 are connected to the top plate 8 and the limit frame 2 respectively.

[0044] Specifically, the guide column 6 and the guide groove 202 are used to guide the up and down movement of the top plate 8. The return spring 7 is a tension spring; at the beginning, the top plate 8 is pulled up, and the return spring 7 applies a pulling force to the top plate 8 to move in the direction of the bottom plate 203. After the identification plate is placed on the bottom plate 203, the top plate 8 can move down under the auxiliary pulling force of the return spring 7 until the identification plate is clamped; and after the top plate 8 clamps the identification plate, the return spring 7 can also apply a pulling force to the top plate 8 to provide a pre-tightening force for the top plate 8 to keep the identification plate clamped. Of course, at this time, the deformation of the return spring 7 is small, and the pulling force it provides is also small, which has little impact on the service life.

[0045] Example 5

[0046] The back plate 1 is also included, and mounting ear plates 102 are provided on both sides of the back plate 1 for fixing in the installation position. The limit frame 2 is fixed on the surface of the back plate 1, and a lug structure is provided in the middle of the top plate 8 toward the back plate 1; a positioning groove 101 is provided at the top of the back plate 1, and a positioning hole 801 is opened on the lug structure of the top plate 8, and a locking member (not shown) passes through the positioning hole 801 and is inserted into the positioning groove 101.

[0047] Specifically, the back plate 1 is used to fix the device at the installation position, for example, by connecting the two mounting ear plates 102 through a clamp and fixing it on a pole; or by fixing it on a wall or a display board through screws and the two mounting ear plates 102. In addition to being connected to the back plate 1 through a locking member (such as a long screw), the convex handle structure of the top plate 8 can also be used as a grip when pulling the top plate 8 up and down.

[0048] Working mode and principle of this utility model:

[0049] When installing the electric facility identification plate, first hold and lift the top plate 8, and the distance between the clamping plate 10 and the bottom plate 203 is increased; hold the identification plate with the other hand, put the bottom end on the bottom plate 203 and insert it into the slot 5, and under the magnetic attraction of the permanent magnet 3, the identification plate is attached to the assembly plate 204 and the friction plate 4, and the identification plate is assisted in positioning. During the installation and disassembly process, it is not easy to tilt forward or slide sideways, and the operation is more convenient; then remove the pulling force on the top plate 8, and under the elastic force of the reset spring 7, the guide column 6 slides down along the guide groove 202 until the clamping groove 11 of the clamping plate 10 is pressed against the top position of the identification plate, and use a locking piece to pass through the positioning hole 801 of the top plate 8 and extend it to be inserted into the positioning groove 101 on the back plate 1 to complete the complete fixation of the identification plate.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
