Description

Technical Field

[0001] The invention relates to the technical field of refueling a power supply vehicle, and in particular to a refueling device and system for a mobile power supply vehicle used in the nuclear power field. Background Art

[0002] In the field of nuclear power, mobile power vehicles are key equipment for emergency power supply, and their stability and reliability are of vital importance. Especially in the event of power outages caused by power grid failures or natural disasters, mobile power vehicles can quickly provide power support for key equipment in nuclear power plants, such as reactor cooling systems and safety monitoring systems, to ensure the safe operation of nuclear power plants.

[0003] However, the existing general power supply vehicle refueling method, whether through an electric oil pump or a hand-cranked oil pump, has some shortcomings, especially when the electric oil pump fails or only a hand-cranked oil pump is available, the control of the refueling process becomes particularly difficult.

[0004] Hand-cranked oil pumps are generally divided into two types: rotary drive and reciprocating push-pull drive. Rotary drive hand-cranked oil pumps have a continuous flow diversion function, but during the refueling process, the operator cannot accurately know whether the vehicle's fuel tank has been filled to the required level, which may cause the tank to be overfilled or insufficient. Although reciprocating push-pull driven hand-cranked oil pumps can change the diversion flow rate by the reciprocating amplitude, this change cannot be precisely controlled and there is also the problem of inaccurate refueling amount.

[0018] The beneficial effects of the mobile power supply vehicle refueling system for the nuclear power field of the present invention are as follows: when the oil level in the power supply vehicle's fuel tank is lower than a preset threshold, the system will send a fuel replenishment signal. After receiving the signal, the operator or the automatic control system will check the status of the electric diversion device to ensure that it is in an operable state. If the electric diversion device is in good condition, the electric diversion device will be started. The specific process is as follows: open the ball valve at the starting end to allow the fuel to flow into the diversion system. The fuel passes through the first expansion joint, which is used to compensate for the pipe deformation caused by temperature changes or pressure changes to ensure the smooth flow of the fuel. The fuel enters the fuel delivery pump, which pressurizes the fuel and delivers it to the next stage under electric drive. The fuel passes through the second expansion joint to further ensure the stability of the pipeline and the smoothness of the fuel. The fuel passes through the check valve, which prevents the fuel from flowing back when the pump stops working, ensuring the unidirectional flow of the fuel. Finally, the fuel enters the power supply vehicle's fuel tank through the ball valve at the end to complete the fuel replenishment process. If the electric diversion device cannot be used due to a fault or power outage, when the manual diversion device needs to be enabled, the operator The operator first closes the ball valves of all electric diversion devices to ensure that the fuel does not flow through the fault path. Then, the ball valve at the starting end of the manual diversion device is opened to allow the fuel to flow in. The operator manually operates the manual pump to pressurize the fuel and deliver it to the next stage. The fuel passes through the check valve to prevent backflow. Finally, the fuel enters the fuel tank of the power supply vehicle through the ball valve at the end to complete the fuel replenishment process. The system is equipped with two sets of electric diversion devices and one set of manual diversion devices to ensure the reliability and continuity of fuel delivery during emergency diesel delivery. The dual protection of electric diversion devices and manual diversion devices ensures that the fuel tank of the power supply vehicle can be quickly and effectively replenished when the fuel is insufficient. The system has high reliability and flexibility and is suitable for various complex environments and emergency situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0040] Example 1, reference Figure 1 to Figure 6 , is the first embodiment of the present invention, which provides a refueling device for a mobile power supply vehicle in the nuclear power field, which can achieve the effect of facilitating the control of the refueling amount of a hand pump, and includes a conveying component 100, which includes a flow guide component 101, and a piston component 102 sliding in the flow guide component 101, and also includes a lifting component 103 fixed to the top of the piston component 102, and also includes a driving component 104 rotating on the top of the flow guide component 101, and also includes an adjusting component 105 sliding inside the driving component 104, the adjusting component 105 and the lifting component 103 are adapted, the driving component 104 can drive the lifting component 103 to operate through the adjusting component 105, the adjusting component 105 can adjust the operating trajectory of the lifting component 103, the lifting component 103 can drive the piston component 102 to drive the flow guide component 101 to operate, so that the flow guide component 101 can guide the oil;

[0041] The metering component 200 includes a prompt component 201 fixed on the driving component 104, the prompt component 201 is connected to the diversion component 101, and a scale component 202 is fixed to the outer wall of the prompt component 201. When the driving component 104 is in operation, it can drive the prompt component 201 to prompt the worker to rotate the number of circles, and at the same time, it can drive the scale component 202 to display a more accurate rotation degree.

[0042] Specifically, Figure 4 In the figure, the guide assembly 101 includes a containing shell 101a, a venting groove 101b is provided at the top of the side end of the containing shell 101a, and a No. 1 one-way valve 101c fixed on the left side of the containing shell 101a, and the No. 1 one-way valve 101c is an oil inlet valve. It also includes a No. 2 one-way valve 101d fixed on the right side of the containing shell 101a, and the No. 2 one-way valve 101d is an oil outlet valve.

[0043] Further, such as Figure 5In the figure, the piston assembly 102 includes a piston 102a that slides on the inner wall of the guide assembly 101, the piston 102a is convex, and its convex small head is set upward. The piston 102a slides on the inner wall of the containment shell 101a in the guide assembly 101, and a convex groove 102b is provided on the top of the piston 102a. The convex groove 102b on the top of the piston 102a is set with a small head downward, and a round block 102c that slides on the large end of the convex groove 102b, and also includes a No. 1 spring 102d fixed in the corresponding convex groove 102b between the piston 102a and the round block 102c, and also includes a connecting rod 102e fixed on the top of the round block 102c, and the outer wall of the connecting rod 102e slides on the top of the containment shell 101a.

[0044] Further, such as Figure 4 In the embodiment, the lifting assembly 103 includes a driving rod 103a fixed to the top of the connecting rod 102e, the bottom of the driving rod 103a slides on the top side of the accommodating shell 101a, and a transverse groove 103b is provided on the top of the driving rod 103a.

[0045] Further, such as Figure 5 , 6 In the figure, the driving component 104 includes a disc 104a rotating on the top of the guide component 101, the disc 104a is connected to the containing shell 101a in the guide component 101, the end face of the disc 104a is provided with a slide groove 104b, the disc 104a is located inside the slide groove 104b and is provided with a schematic groove 104c, and a center rod 104d fixed at the center of the disc 104a, and also includes a crank 104e fixed at the end of the center rod 104d.

[0046] Further, such as Figure 6 In the figure, the adjustment component 105 includes a slider 105a that slides in the driving component 104, the slider 105a slides in the slide groove 104b in the driving component 104, the end face of the slider 105a is provided with a scale groove 105b, and also includes a screw rod 105c that is movably connected to the center of the slider 105a, the screw rod 105c is connected to the driving component 104, the screw rod 105c is rotatably connected to the disk 104a in the driving component 104, and also includes a transmission rod 105d fixed to the end face of the slider 105a.

[0047] When the conveying component 100 is used, first, the slider 105a and the transmission rod 105d can be driven downward by twisting the screw rod 105c, and the transmission rod 105d will press the connecting rod 102e and the piston assembly 102 downward. At this time, the scale groove 105b can be observed through the indicator groove 104c to see whether the torque adapted to it has been reached. At this time, the crank 104e can be held by hand to drive the center rod 104d and the disc 104a to rotate. The slider 105a and the transmission rod 105d in the slide groove 104b of the 4a rotate around the disc 104a. Since the transmission rod 105d is located inside the transverse groove 103b when rotating, the transmission rod 105d can drive the driving rod 103a, the connecting rod 102e, and the piston assembly 102 to move back and forth. Therefore, the No. 1 check valve 101c connected to the containing shell 101a can suck the oil into the containing shell 101a, and then discharge it through the No. 2 check valve 101d. , during this process, when the crank 104e is at the bottom, it is not easy for the user to exert force, so during this starting process, in the piston assembly 102, the connecting rod 102e drives the round block 102c to squeeze the No. 1 spring 102d downward until the round block 102c hits the convex groove 102b, and then the piston 102a can be driven to move downward. When the crank 104e is at the top, in the piston assembly 102, the connecting rod 102e will drive the round block 102c to move upward. During this process, the No. 1 spring 102d will also rebound and push the round block 102c until the round block 102c hits the top of the convex groove 102b, and the round block 102c can drive the piston 102a to move upward. The brief pause on both sides can reduce the crank 104e when it is at the top and bottom, and better start and transition. In addition, the No. 1 check valve 101c and the No. 2 check valve 101d are in a state of being closed or opened during this process, so this pause can reduce the problem of oil reflux.

[0048] In summary, since the driving component 104 and the adjusting component 105 form an adjustable eccentric wheel structure to drive the lifting component 103 to reciprocate, and the adjusting component 105 has a scale groove 105b to indicate the adjusted value, the reciprocating distance of the piston component 102 in the guide component 101 is limited, and the amount of oil guided by the piston component 102 in the guide component 101 at one time can be combined with the number of rotations to simply judge the oil guidance amount of the conveying component 100. This makes it easy to know the amount of oil to be refueled and is suitable for people with great or small strength, thereby improving practicality and applicability.

[0049] Example 2, reference Figures 1 to 8 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a metering component 200 for a mobile power supply vehicle refueling device in the nuclear power field, which solves the problem of not being able to remember the number of turns when rotating the crank 104e. Figure 8It includes, the prompt component 201 includes a ring 201a fixed on the driving component 104, the ring 201a is fixed on the outer wall of the center rod 104d in the driving component 104, the outer wall of the ring 201a is provided with a plurality of grooves 201b, the grooves 201b are four, and the four grooves 201b are evenly arranged on the outer wall of the ring 201a, so that the distance between each groove 201b is a quarter of a circle, and a ball 201c adapted for the groove 201b, and also includes a slide bar 201d rolling on the bottom of the ball 201c, and also includes a device shell 201e sliding on the bottom of the slide bar 201d, and also includes a No. 2 spring 201f fixed between the device shell 201e and the slide bar 201d.

[0050] Specifically, Figure 7 In the figure, the scale component 202 includes a scale ring 202a fixed to the outer wall of the prompt component 201, the scale ring 202a is fixed to the outer wall of the circular ring 201a in the prompt component 201, and a pointer 202b fixed to the top of the diversion component 101 corresponding to the top of the scale ring 202a, and the pointer 202b is fixed to the top of the accommodating shell 101a in the diversion component 101 corresponding to the top of the scale ring 202a.

[0051] The rest of the structure is the same as that of Example 1.

[0052] During use, when the crank 104e drives the center rod 104d to rotate, the center rod 104d will also drive the ring 201a to rotate, so that the ball 201c will be squeezed out of the first groove 201b and enter the outer wall of the ring 201a. During this process, the ball 201c will squeeze the slide bar 201d and the second spring 201f. When the second groove 201b moves to the ball 201c, the second spring 201f will drive the slide bar 201d and the ball 201c to quickly fall into the second groove 201b, thereby making a sound, prompting the user to rotate a quarter of a turn. When in use and after rotating the required number of turns, the crank 104e can continue to be shaken to drive the center rod 104d. At this time, the scale ring 202a driven by the ring 201a can be observed. At this time, the pointer 202b points to the scale ring 202a, which is a more accurate degree of rotation, so that the amount of refueling can be more accurately known and controlled.

[0053] Embodiment 3 is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a mobile power supply vehicle refueling system for the nuclear power field, which has the function of emergency refueling of the power supply vehicle tank, and includes an emergency diesel generator set fuel main tank, a power supply vehicle tank, an electric diversion device and a manual diversion device;

[0054] Two sets of electric diversion equipment, which include a ball valve, an expansion joint, a fuel transfer pump, another expansion joint, a check valve and another ball valve in this order, and the electric diversion equipment is arranged in this order to transfer fuel from the main fuel tank of the emergency diesel generator set to the fuel tank of the power supply vehicle;

[0055] A set of manual diversion equipment, which includes a ball valve, a manual pump, a check valve and another ball valve in sequence. The manual diversion equipment is also arranged in this order and is used to transfer fuel from the emergency diesel generator set fuel main tank to the power supply vehicle tank through manual operation when the electric diversion equipment is unavailable.

[0056] During use, when the fuel level in the power supply vehicle's fuel tank is lower than the preset threshold, the system will send a fuel replenishment signal. After receiving the signal, the operator or automatic control system will check the status of the electric diversion device to ensure that it is in an operable state. If the electric diversion device is in good condition, the electric diversion device will be started. The specific process is as follows: open the ball valve at the starting end to allow the fuel to flow into the diversion system. The fuel passes through the first expansion joint, which is used to compensate for pipe deformation caused by temperature changes or pressure changes to ensure smooth fuel flow. The fuel enters the fuel delivery pump, which is electrically driven to pressurize the fuel and deliver it to the next stage. The fuel passes through the second expansion joint to further ensure the stability of the pipeline and the smoothness of the fuel. The fuel passes through the check valve, which prevents the fuel from flowing back when the pump stops working, ensuring one-way flow of the fuel. Finally, the fuel enters the power supply vehicle's fuel tank through the ball valve at the end to complete the fuel replenishment process. If the electric diversion device fails for some reason, the fuel will not be able to flow back. When the manual diversion device is used due to a fault or power outage and cannot be used, the operator must first close the ball valves of all electric diversion devices to ensure that the fuel does not flow through the fault path. Then, the ball valve at the starting end of the manual diversion device is opened to allow the fuel to flow in. The operator manually operates the manual pump to pressurize the fuel and transport it to the next stage. The fuel passes through the check valve to prevent backflow. Finally, the fuel enters the fuel tank of the power supply vehicle through the ball valve at the end to complete the fuel replenishment process. The system is equipped with two sets of electric diversion devices and one set of manual diversion devices to ensure the reliability and continuity of fuel delivery during emergency diesel delivery.

[0057] In summary, the dual protection of electric diversion equipment and manual diversion equipment ensures that the fuel tank of the power supply vehicle can be quickly and effectively replenished with fuel when the fuel is insufficient. The system has high reliability and flexibility and is suitable for various complex environments and emergency situations.
