The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1-2 are schematic structural diagrams of a mat board of a prefabricated box transformer substation according to an embodiment of the present application. The embodiment of the application provides a cushion plate of a preassembled box transformer substation, which comprises the following components:
The base plate 100 comprises an elastic body 102, wherein the elastic body 102 is made of an elastic material, the elastic body 102 is used for supporting a preassembled box transformer 500, a detection unit 103 is arranged in the elastic body 102, and the detection unit 103 is used for detecting deformation generated when the elastic body 102 is extruded;
The control unit is electrically connected with the detection unit 103, determines the vibration amplitude of the preassembled box transformer 500 according to the deformation detected by the detection unit 103, and determines whether the vibration amplitude of the preassembled box transformer 500 reaches a set threshold value;
and the warning unit 210 is electrically connected with the control unit, and the control unit controls the warning unit 210 to generate corresponding warning information after determining that the vibration amplitude of the preassembled tank transformer 500 reaches the threshold value.
For example, the elastic body 102 may be made of a common elastic material such as rubber, silica gel, etc., and the detecting unit 103 may be a strain gauge, where when the strain gauge is connected to the control unit, the resistance will change when the strain gauge deforms along with the elastic body, and thus the current or voltage will change, and the change is received by the control unit to determine the shape variable.
The control unit can adopt devices such as a PLC, an MCU, a singlechip and the like, and can process digital signals, and signals generated by the strain gauge are analog signals, so that the electric signals are conditioned before the strain gauge transmits the electric signals to the control unit, and the conditioning comprises filtering and denoising, power amplification, analog-to-digital conversion and the like. The generated digital signal may be input to a control unit, which may determine the deformation amount of the strain gauge, i.e., the deformation of the elastic body 102, according to the level of the input digital signal.
The control unit may be electrically connected to the storage unit, and the storage unit may employ a flash memory chip in which a threshold value written in advance by an administrator is stored, which may be determined by an experimenter through a large number of experiments, in which different vibration amplitudes may be applied to the prefabricated box transformer, and then the influence of the different vibration amplitudes on the prefabricated box transformer is determined, and vibration amplitudes in which a representative, e.g., displacement, deformation, damage, etc., of equipment or devices inside the prefabricated box transformer is generated are taken as the threshold value, and written in the storage unit.
In the embodiment of the present application, the storage unit further stores mapping data of deformation and vibration amplitude, and the control unit obtains the deformation detected by the detection unit 103 and then queries the vibration amplitude corresponding to the deformation in the mapping data. The mapping data can also be determined by experimenters through a large number of experiments, different vibration amplitudes can be applied to the elastic body during the experiments, deformation corresponding to the different vibration amplitudes is detected, after a plurality of groups of vibration amplitudes and corresponding deformation are obtained through measurement, function fitting can be carried out, and a relation function of the vibration amplitudes and the deformation can be obtained, and the relation function can be used as the mapping data. In a subsequent use, after the control unit determines the deformation of the elastic body 102, the deformation may be input into the relation function, and the vibration amplitude corresponding to the deformation is obtained, and then the calculated vibration amplitude is compared with the threshold value, so as to control the alarm unit 210 accordingly.
In one possible embodiment, the base plate 100 further comprises: the housing 101 is hollow, the elastic body 102 is arranged inside the housing 101, the housing 101 is provided with a positioning groove 110 penetrating through the inner side surface and the outer side surface, and the detection unit 103 is arranged at a position corresponding to the positioning groove 110 inside the elastic body 102.
Illustratively, the housing 101 may be made of a hard material, such as a hard plastic, metal, etc., that encloses the elastomer 102 and may provide some protection to the elastomer 102.
The bottom of the prefabricated box transformer 500 is typically provided with a positioning post, and the positioning groove in the present application is matched with the positioning post, including the position and the size of the positioning groove 110, so that when the prefabricated box transformer 500 is placed on the casing 101, the positioning post can be inserted into the positioning groove 110 to make contact with the elastomer 102, and apply pressure to the elastomer 102.
Further, the housing 101 is provided with a fixed support column 300 on the side where the positioning groove 110 is provided, and the height of the fixed support column 300 is smaller than the distance between the bottom of the prefabricated box transformer 500 and the housing 101 when the prefabricated box transformer 500 is placed on the elastic body. Specifically, when the positioning columns are provided at the bottom of the prefabricated box transformer 500, the height of the positioning columns needs to be greater than the sum of the three dimensions of the height of the fixed support column 300, the depth of the positioning grooves 110, and the sinking height of the positioning columns under the weight of the prefabricated box transformer 500.
A plurality of fixed support columns 300 may be provided on the housing 101, preferably on an edge of the housing 101, for example on two or more opposite edges of the housing 101. When the positioning column at the bottom of the preassembled box transformer 500 is inserted into the positioning groove 110, the distance between the bottom of the preassembled box transformer 500 and the shell 101 is still larger than the height of the fixed support column 300 in a static state, so that the preassembled box transformer 500 can shake within a certain range when being vibrated to apply pressure to an elastomer, and when the vibration amplitude is overlarge, the fixed support column 300 is in contact with the preassembled box transformer 500 to provide protection for the preassembled box transformer 500, so that damage caused by the fact that the vibration amplitude of the preassembled box transformer 500 exceeds the designed maximum value is avoided.
In one possible embodiment, the movable support column 400 is removably mounted to the housing 101, and the height of the movable support column 400 is the same as the height of the fixed support column 300.
Illustratively, the flexible support column 400 may be placed directly on the housing 101 or a socket may be provided on the housing 101 that mates with the flexible support column 400, and the flexible support column 400 may be removably inserted into the socket.
In the present application, the slots may be disposed vertically, i.e., along the thickness direction of the substrate 100, or laterally, i.e., along the width direction of the substrate 100. When a transverse arrangement is used, an inverted T-shaped or triangular slide rail can be provided at the bottom of the flexible support column 400 and the slot can be configured to match the slide rail, so that the flexible support column 400 can be slid into the slot.
The number of the positioning slots 110 arranged on the shell 101 can be larger than the number of the positioning columns at the bottom of the preassembled type box transformer substation 500, two positioning slots 110 at different positions can form a group, and two positioning slots 110 in the group can be matched with the preassembled type box transformer substation 500 with a specific size, so that the cushion plate can be matched with a plurality of preassembled type box transformer substations 500 with different sizes, and the universality of use is improved.
In one possible embodiment, the method further comprises: the stand 200 is of a hollow structure, the control unit is arranged inside the stand, the stand 200 is arranged on one side of the bottom plate 100, and the warning unit 210 is arranged on the top end of the stand 200.
Illustratively, the upright posts may be disposed on the left, right or front side of the floor panel 100, and the warning unit 210 is located in a range visible to the driver through the outside or inside rearview mirror when the floor panel is placed on the truck, and the state of the warning unit 210 can be checked at any time through the rearview mirror when the driver encounters a relatively bumpy road section to take measures such as slowing down the vehicle or changing the driving line, etc. to reduce the bumpy.
In one possible embodiment, the thresholds have multiple sets, and the multiple sets of thresholds correspond to different vibration amplitudes, and the control unit controls the alarm unit 210 to generate alarm information corresponding to the vibration amplitudes.
Illustratively, the warning unit 210 preferably employs a warning light that generates warning information in a luminous manner. When the vibration amplitude of the preassembled box transformer substation 500 reaches different thresholds, the warning unit 210 can form different warning information through different lights with different colors or different lighting modes. For example, when the vibration amplitude of the current road section is relatively small, the warning unit 210 may emit yellow light or flash once, and when the vibration amplitude is relatively large, the warning unit 210 may emit red light or flash twice continuously.
The embodiment of the application also provides a transportation safety evaluation method of the preassembled box transformer substation, which comprises the following steps:
detecting deformation of the elastic body 102 supporting the preassembled bin transformer 500 during transportation;
Determining the vibration amplitude of the preassembled box transformer 500 according to the deformation;
determining whether the vibration amplitude of the preassembled tank transformer 500 reaches a set threshold;
After determining that the vibration amplitude of the preassembled tank transformer 500 reaches the threshold value, corresponding warning information is generated.
