DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Embodiment 1:

[0021] like Figures 1 to 9 Please pay attention to Figure 4 , Figure 6 , Figure 7As shown, a multifunctional mobile emergency voltage regulating device according to an embodiment of the present invention comprises a mobile emergency vehicle 100; a voltage regulator 200 arranged on the mobile emergency vehicle 100; a control box 300 arranged on the voltage regulator 200, wherein a wire hole 403a1 is provided at the bottom of the control box 300, a sliding limit groove 403a2 is provided at the bottom of the control box 300, and the sliding limit groove 403a2 is connected with the wire hole 403a1; a wire fixing mechanism 403 arranged at the bottom of the switch cabinet, wherein the wire fixing mechanism 403 is used to quickly fix the cable; a wire tightening mechanism 404 arranged on the wire fixing mechanism 403; and a control module connected to the wire fixing mechanism 403 through a signal, wherein the control module strengthens and tightens the cables to be connected according to the state of the wire fixing mechanism 403 itself; Among them, the wire fixing mechanism 403 includes: a wire fixing plate 403b, which is L-shaped, one end of the wire fixing plate 403b is placed in the sliding limit groove 403a2 to slide, and the other end of the wire fixing plate 403b is placed in the wire hole 403a1; a wire fixing tension spring 403c whose two ends are respectively fixed to the side wall of the wire hole 403a1 and the wire fixing plate 403b, and a pressure gauge for monitoring the elastic force generated by the wire fixing tension spring 403c when it is under pressure.

[0022] Specifically, the mobile emergency vehicle 100 provides mobility and portability of the overall equipment, so that the equipment can quickly arrive at the scene when needed. Before the mobile emergency vehicle 100 arrives at the designated location, the cable is first connected to the control box 300. When the cable needs to be connected to the control box 300, a socket 401 is fixedly installed at the bottom of the control box 300. First, the cable is connected to the inside of the plug 402 through the tightening mechanism 404 and the fixing mechanism 403. When the cable is successfully connected to the inside of the plug 402, the plug 402 is inserted into the socket 401. When the plug 402 and the socket 401 are connected, the contacts in the plug 402 usually correspond to the contacts in the socket 401, and an electrical connection is established between the contacts. At this time, the cable and the control box 300 are electrically connected.

[0023] When the cable passes through the wire fixing mechanism 403, the cable first passes through the wire hole 403a1, and then passes through the wire fixing plate 403b. When the cable passes through the wire fixing plate 403b, the wire fixing tension spring 403c is compressed, and the wire fixing tension spring 403c generates elastic force to push the wire fixing plate 403b in the opposite direction, thereby maintaining the clamping force of the wire fixing plate 403b on the cable. At this time, the position of the cable and the plug 402 of the circular connector 400 can be fixed by the wire fixing mechanism 403. When the mobile emergency vehicle 100 drives the voltage regulator 200 and the cable to the designated position for rapid response, In an emergency, the control module will determine whether the cable is sufficiently clamped by the wire fixing mechanism 403 based on the state of the wire fixing mechanism 403 itself (i.e., the elastic force of the wire fixing spring 403c), and then determine whether the cable needs to be further tightened. If the cable needs to be further tightened, the control module will trigger the tightening mechanism 404 to perform additional tightening operations on the cable. The cable can be quickly fixed through the wire fixing mechanism 403, and then in an emergency, the cable can be quickly electrically connected to the control box 300, which can reduce the connection time and thus speed up the startup of the emergency equipment.

[0024] Please pay attention to Figure 4 , Figure 7 As shown, the tensioning mechanism 404 includes: a plurality of clamps 404a fixedly connected to the lower end of the insertion tube 403a, the plurality of clamps 404a surround the wire hole 403a1 and are elastic; an inclined pressure plate 404b fixedly connected to the side wall of the lower end of the clamp 404a; a ring plate 404c sleeved on the outside of the clamp 404a; an electric push rod 404d whose two ends are respectively fixedly connected to the lower end of the control box 300 and the top end of the ring plate 404c; and a tensioning tube 404e fixedly connected to the lower end of the insertion tube 403a, the tensioning tube 404e is provided with a built-in hole 404e1, and the clamp 404a, the inclined pressure plate 404b, the ring plate 404c, and the electric push rod 404d are all placed in the built-in hole 404e1.

[0025] Specifically, when it is necessary to further tighten the cable, the control unit controls the output end of the electric push rod 404d to extend and move vertically downward, and the output end of the electric push rod 404d extends and moves vertically downward to drive the ring plate 404c to move downward, and the ring plate 404c moves downward to continuously squeeze the oblique pressure plate 404b, thereby driving the lower ends of multiple clamping plates 404a to approach the cable, thereby squeezing the cable to tighten the cable, thereby preventing the mobile emergency vehicle 100 from separating from the plug 402 of the circular connector 400 when driving the voltage regulator 200, thereby preventing the electrical connection between the cable and the voltage regulator 200 formed through the control box 300 from being disconnected. When it is necessary to control the tensioning mechanism 404 to loosen the cable, the control unit controls the output end of the electric push rod 404d to shorten and move vertically upward, thereby driving the ring plate 404c, the oblique pressure plate 404b, and the clamping plate 404a to reset, and then the clamping plate 404a releases its grip on the cable to avoid damage to the cable caused by excessive tightening of the cable.

[0026] Please refer to FIG. 8 , the tightening mechanism 404 further includes a rubber strip 404f fixedly connected to the inner wall end of the lower end of the clamping plate 404a.

[0027] Specifically, the rubber strip 404f has elasticity and friction, which can increase the clamping force and stability of the clamping plate 404a on the cable, and also prevent the cable from being cut when the end of the clamping plate 404a clamps the cable too tightly.

[0028] Please pay attention to Figure 8 As shown, the turning point of the fixing plate 403b even has a sliding slope 403b1, and the inner wall of the fixing plate 403b is provided with a curved surface 403b2.

[0029] Specifically, when the wire fixing tension spring 403c is in a normal state, the end of the sliding slope 403b1 is flush with the side wall of the wire hole 403a1. At this time, the cable can enter the wire hole 403a1 more smoothly. The design of the sliding slope 403b1 reduces the resistance of the cable in the process of sliding into the control box 300, making the operation smoother; the arc surface 403b2 can increase the contact area between the wire fixing plate 403b and the cable, thereby improving the clamping effect.

[0030] Please pay attention to Figure 5 , Figure 7 As shown, a plurality of circular connectors 400 are provided at the bottom of the control box 300 , and a plurality of wire fixing mechanisms 403 and wire tightening mechanisms 404 are also adaptively provided at the bottom of the switch cabinet.

[0031] Specifically, by providing multiple circular connectors 400, the need for multiple cables to enter and exit simultaneously can be met. The design of multiple cable fixing mechanisms 403 and cable tightening mechanisms 404 improves the fixing and tightening effect of the cables, ensuring the stability and safety of the cables during movement.

[0032] Please pay attention to Figure 5 As shown, the control box 300 is further provided with a plurality of ventilation holes 301 at the bottom, and the ventilation holes 301 are provided with ventilation nets 302 .

[0033] Specifically, when the device is working, the electrical components inside the control box 300 will generate heat during operation. By setting the vents 301 and the ventilation net 302, the heat dissipation effect of the device can be increased to prevent the internal electrical components from overheating, thereby improving the heat dissipation effect of the control box 300 and preventing the internal electrical components from being damaged due to overheating. The design of the ventilation net 302 can prevent dust and debris from entering the interior of the device, thereby ensuring the cleanliness and normal operation of the equipment.

[0034] Embodiment 2:

[0035] like Figures 1 to 9 Please pay attention to Fig. 9 As shown, the control module includes: a state prediction unit, which is used to predict the bumping force generated by the mobile emergency vehicle 100 during driving. The mobile emergency vehicle 100 will cause bumps due to road conditions, driving speed, and driving distance when driving the voltage regulator 200. The bumps will cause the cable fixing mechanism 403 to affect the clamping of the cable; An elastic force monitoring unit, the elastic force detection unit is used to collect the elastic force generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes monitored by the pressure gauge; The data processing unit, the state prediction unit transmits the predicted bump force data generated by the mobile emergency vehicle 100 during driving to the data processing unit, the elastic force monitoring unit transmits the monitored elastic force data generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes to the data processing unit, the data processing unit performs weighted summation based on the bump force data generated by the mobile emergency vehicle 100 during driving and the elastic force data generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes to comprehensively determine when to start the wire tightening mechanism 404 to tighten the cables to avoid the cables and the voltage regulator 200 being separated when the mobile emergency vehicle 100 is driving the voltage regulator 200, and when to control the wire tightening mechanism 404 to loosen the cables to avoid excessive tightening of the cables causing damage to the cables; The control unit controls the cable tightening mechanism 404 to tighten the cable or loosen the cable according to the analysis result of the data processing unit.

[0036] Please pay special attention to the figure. By collecting a large amount of road condition information and vehicle driving data and conducting statistical analysis on them, a bumpiness assessment model can be established. The model can automatically output the vehicle bumpiness assessment result based on the input road condition information and vehicle driving data.

[0037] Specifically, the automatic adjustment of the control module is mainly related to two factors, one is the bumpy force data generated by the mobile emergency vehicle 100 during driving, and the other is the elastic force data generated by the wire-fixing spring 403c when the wire-fixing plate 403b clamps cables of different sizes. The bumpy force data generated by the mobile emergency vehicle 100 during driving and the elastic force data generated by the wire-fixing spring 403c when the wire-fixing plate 403b clamps cables of different sizes are weighted and summed to comprehensively determine when to start the wire-tightening mechanism 404 to tighten the cables to avoid separation of the cables from the voltage regulator 200 when the mobile emergency vehicle 100 is driving the voltage regulator 200, and when to control the wire-tightening mechanism 404 to loosen the cables to avoid damage to the cables caused by over-tightening of the cables.

[0038] In order to combine the bump force data generated by the mobile emergency vehicle 100 during driving and the elastic force data generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes through weighted summation, we have marked them as and , and introduce two weights and to indicate their importance in the weighted sum.

[0039] The weighted sum expression can be: ; in: It represents the bump force data generated by the mobile emergency vehicle 100 during driving.

[0040] It represents the elastic force data generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes.

[0041] is the weight of the bump force data generated by the mobile emergency vehicle 100 during driving.

[0042] It is the weight of the elastic force data generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes.

[0043] Among them, the result of the weighted summation reflects whether the tensioning mechanism 404 is started to strengthen the tightening degree of the cable. A threshold T can be set to determine when to control the tensioning mechanism 404 to strengthen the tightening degree of the cable through the control unit, and when to control the tensioning mechanism 404 to loosen the cable, so as to achieve precise control of the tightening force of the cable and avoid over-tightening or under-tightening of the cable.

[0044] Wherein: T is a preset threshold value, which is set according to the actual situation. When the comprehensive evaluation result exceeds the threshold value T, it means that the tightening mechanism 404 needs to be started to tighten the cable. When the comprehensive evaluation result is lower than the threshold value T, it means that the tightening mechanism 404 needs to be controlled to loosen the cable.

[0045] ; In practical applications, the weight and The choice of should be based on the specific application scenario and requirements, ensuring that they can accurately reflect the relative importance in the scenario. At the same time, the sum of these two weights should usually be equal to 1 (or 100%, if expressed as a percentage) to indicate that they together constitute the total weight of the entire weighted sum.

[0046] The state prediction unit transmits the data of the bump force generated by the mobile emergency vehicle 100 during driving to the data processing unit, and the elastic force monitoring unit transmits the data of the elastic force generated by the wire fixing spring 403c when the wire fixing plate 403b clamps cables of different sizes to the data processing unit. The data processing unit substitutes the relevant information into In the process, the data processing unit determines when to start the tightening mechanism 404 to tighten the cable according to the comparison and the size of T, so as to prevent the cable from being separated from the voltage regulator 200 when the mobile emergency vehicle 100 is driving the voltage regulator 200, and when to control the tightening mechanism 404 to loosen the cable to avoid damage to the cable caused by over-tightening of the cable. At this time, the control unit activates the tightening mechanism 404 to tighten the cable, and the control unit controls the output end of the electric push rod 404d to extend and move vertically downward, and the output end of the electric push rod 404d extends and moves vertically downward to drive the ring plate 404c to move downward, and the ring plate 404c moves downward to continuously squeeze the oblique pressure plate 404b, thereby driving the lower ends of the multiple clamping plates 404a to approach the cable, thereby squeezing the cable to tighten the cable, thereby preventing the cable from being separated from the voltage regulator 200 when the mobile emergency vehicle 100 is driving the voltage regulator 200. At this time, the control unit controls the output end of the electric push rod 404d to shorten and move vertically upward, thereby driving the ring plate 404c, the inclined pressure plate 404b, and the clamping plate 404a to reset, and then the clamping plate 404a releases its grip on the cable to avoid damage to the cable caused by over-tightening of the cable.

[0047] The above formulas are all dimensionless and numerical calculations. The formula is a formula for the most recent real situation obtained by collecting a large amount of data and performing software simulation. The preset parameters in the formula are set by technicians in this field according to actual conditions.
