In the liquor production process, from raw material processing to finished product packaging, all links have begun to apply automated equipment and technology. The automation of the loading and unloading process of on-board liquor has also developed in this context, so the vehicle static elimination safety protection measures involved in the loading and unloading process must also be automated.

[0003] CN221081608U discloses a static elimination device for tank trucks in a hazardous chemicals tank area. After controlling the guide mechanism to rotate around a support frame to a predetermined position, the locking assembly of the locking mechanism is buckled with a buckle plate to prevent the guide mechanism from rotating. Then, the elastic grounding wire passing through the guide mechanism is controlled to be connected to the tank truck to eliminate static electricity. However, in the above scheme, the static elimination process is not monitored, and the stability and reliability of the static elimination process cannot be ensured. It is impossible to confirm whether the static electricity is completely eliminated, and static electricity is easily residual, which still poses a safety hazard. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present invention is: how to ensure the stability and controllability of the static electricity removal process.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

[0006] A vehicle static electricity elimination device comprises a support seat, the support seat is slidably provided with a static electricity elimination shaft, the end of the static electricity elimination shaft away from the support seat is provided with a conductive head, the conductive head is used to abut the static electricity elimination contact plate of the vehicle; a spring is sleeved on the outer side of the static electricity elimination shaft, the two ends of the spring respectively abut the conductive head and the support seat, and a pressure sensor is arranged between the spring and the support seat; a first conductive block is arranged at the end of the static electricity elimination shaft away from the conductive head, and a second conductive block is arranged at a position corresponding to the first conductive block of the support seat, when the spring is in a naturally extended state, the first conductive block and the second conductive block are in contact; a driving member is arranged on the side of the support seat away from the conductive head, the driving end of the driving member is connected to the support seat, and the driving direction of the driving member is consistent with the extension direction of the static electricity elimination shaft; the first conductive block is electrically connected to a static electricity transmission wire, and the static electricity transmission wire is connected to an electrical conduction induction member and a grounding wire; and a control system is also included, and the control system is electrically connected to the pressure sensor, the driving member and the static electricity release judgment sensor respectively.

[0007] Furthermore, the above-mentioned conductive head, a static electricity removal shaft, a pressure sensor and a first conductive block form a static electricity removal unit, and a plurality of the above-mentioned static electricity removal units are arranged in parallel at intervals.

[0008] Furthermore, it also includes a guide plate, the guide plate is provided with a guide hole, the multiple first conductive blocks of the multiple static electricity removal units are all connected to the guide plate, the support seat is provided with a guide column that slides with the guide hole, and the guide column is arranged parallel to the static electricity removal axis.

[0014] The following steps are involved:

[0015] S1: Before the conductive head contacts the anti-static contact plate of the vehicle, the electrical conductivity sensing element detects the on-off status of the circuit and transmits the detected on-off signal a of the anti-static circuit to the control system. If the anti-static circuit is on, the control system issues a normal working instruction. If the anti-static circuit is off, the control system issues a maintenance instruction.

[0017] S3: When the conductive head stably contacts the anti-static contact plate of the vehicle, the electrical conduction sensing element determines the on / off signal a of the anti-static circuit.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 3As shown, an embodiment of the present application proposes a vehicle static electricity elimination device, including a support seat 9, on which a static electricity elimination shaft 3 is slidably provided, and a conductive head 2 is provided at one end of the static electricity elimination shaft 3 away from the support seat 9, and the conductive head 2 is used to abut against the static electricity elimination contact plate 1 of the vehicle; a spring 4 is sleeved on the outer side of the static electricity elimination shaft 3, and the two ends of the spring 4 abut against the conductive head 2 and the support seat 9 respectively, and a pressure sensor 5 is provided between the spring 4 and the support seat 9; a first conductive block 6 is provided at one end of the static electricity elimination shaft 3 away from the conductive head 2, and a second conductive block is provided at a position corresponding to the first conductive block 6 of the support seat 9 7. When the spring 4 is in a naturally extended state, the first conductive block 6 is in contact with the second conductive block 7; a driving member 10 is provided on the side of the support seat 9 away from the conductive head 2, the driving end of the driving member 10 is connected to the support seat 9, and the driving direction of the driving member 10 is consistent with the extension direction of the static electricity removal axis 3; the first conductive block 6 is electrically connected to the static electricity transmission wire 8, and the static electricity transmission wire 8 is connected to the electrical conduction sensing member 12 and the grounding wire 11; and also includes a control system 13, which is electrically connected to the pressure sensor 5, the driving member 10 and the static electricity release judgment sensor respectively.

[0029] First of all, it should be stated that the device automatically connects and contacts with the vehicle, and realizes real-time monitoring and management of the static discharge process of the loading and unloading vehicle through sensors, control system 13, etc. This device and control technology improves the automation level and convenience of vehicle static elimination operations, while also reducing the management risk of the static elimination process being unable to be monitored in real time, effectively avoiding static electricity accumulation, and ensuring the safety and stability of the loading and unloading operation environment.

[0030] Specifically, the vehicle's anti-static contact plate 1 is connected to the vehicle body, and the vehicle body can be connected to a complete anti-static circuit. The plate surface of the anti-static contact plate 1 is directly connected after contacting the conductive head 2. However, in the actual working process, the surface of the anti-static contact plate 1 may be rusted or corroded. Therefore, in order to improve the above situation, the conductive head 2 is cone-shaped, and the cone-shaped conductive head 2 contacts the anti-static contact plate 1, which can directly pierce the rust layer or corrosion layer, thereby ensuring good conductive contact.

[0031] Moreover, when the conductive head 2 is not in contact with the static electricity elimination contact plate 1, the spring 4 is in a naturally extended state. At this time, the first conductive block 6 and the second conductive block 7 are connected, that is, the static electricity elimination circuit is connected to the support seat 9. At this time, the first conductive block 6, the second conductive block 7, the static electricity transmission wire 8, the electrical conduction sensing element 12, the grounding wire 11 and the control system 13 are sequentially connected to form a path. The electrical conduction sensing element 12 can be used to sense whether the circuit is in a conductive state and whether it meets the conditions for static electricity elimination of the vehicle. If the conductive state is detected, the vehicle is put in place, and the control system 13 controls the driving element 10 to drive the support seat 9 to move, so that the conductive head 2 stably abuts against the static electricity elimination contact plate 1 of the vehicle. At this time, the first conductive block 6 and the second conductive block 7 are separated. At this time, the vehicle and the static electricity contact plate, the static electricity elimination shaft 3, The first conductive block 6, the static electricity transmission conductor 8, the electrical conductivity sensing element 12, the grounding wire 11 and the control system 13 form a conductive path, at which time a stable static electricity removal process is achieved, and during the static electricity removal process, the static electricity removal process can be continuously sensed by the electrical conductivity sensing element 12, wherein the electrical conductivity sensing element 12 is mainly used to determine whether a conductive loop is formed to determine whether the static electricity elimination device and related wire lines are faulty. The determination method of whether a conductive loop is formed can be changed to directly output current, voltage, and resistance, that is, the judgment of the circuit being on or off is achieved through the sensing elements corresponding to the current, voltage, and resistance. Preferably, the electrical conductivity sensing element 12 is an electrostatic release judgment sensor, which is an existing electrostatic sensor that can detect the flow and existence of static electricity in the static electricity removal circuit.

[0032] The control system 13 is an existing circuit detection and control system 13 , which senses the sensor signal and the circuit on / off signal and controls the control circuit of the driving member 10 .

[0033] In order to ensure that the static electricity removal shaft 3 can stably slide relative to the support seat 9, the above-mentioned conductive head 2, the static electricity removal shaft 3, a pressure sensor 5 and a first conductive block 6 form a static electricity removal unit, and the multiple static electricity removal units are arranged in parallel at intervals. By allowing the multiple parallel static electricity removal shafts 3 to slide relative to the support seat 9 at the same time, the occurrence of tilting and offset can be avoided, and the multiple conductive heads 2 can abut the electrostatic contact plate at the same time, which can further ensure the stability of the circuit conduction state, and the above-mentioned static electricity removal shaft 3 and the above-mentioned support seat 9 are slidably matched through linear bearings to further ensure the stability of the moving state of the static electricity removal shaft 3.

[0034] It also includes a guide plate, which is provided with a guide hole. The multiple first conductive blocks 6 of the multiple static electricity removal units are all connected to the guide plate. The support seat 9 is provided with a guide column 14 that slides with the guide hole. The guide column 14 is arranged parallel to the static electricity removal axis 3 to ensure a stable guiding effect.

[0035] The driving member 10 includes a pneumatic push rod device, which has the effects of fast response and precise control, and can ensure rapid response under the control of the control system 13 to realize the conduction and interruption process of the static electricity removal circuit, and has a better control effect.

[0036] This embodiment also proposes a vehicle static elimination method, comprising the following steps:

[0037] S1: Before the conductive head 2 contacts the anti-static contact plate 1 of the vehicle, the electrical conduction induction element 12 detects the on-off status of the circuit and transmits the detected on-off signal a of the anti-static elimination circuit to the control system 13. If the anti-static elimination circuit is on, the control system 13 issues a normal working instruction. If the anti-static elimination circuit is blocked, the control system 13 issues a maintenance instruction. That is to say, at this time, the first conductive block 6, the second conductive block 7 and the support seat 9 form a whole. At this time, the electrical conduction induction element 12 detects the on-off status of the circuit, which can detect the connectivity of the above-mentioned electrostatic transmission wire 8, the electrical conduction induction element 12, the grounding wire 11 and the control system 13. If abnormalities and faults are found, they can be repaired in time. Wherein, the anti-static elimination circuit includes the first conductive block 6, the second conductive block 7, the electrostatic transmission wire 8, the electrical conduction induction element 12, the grounding wire 11 and the control system 13 which are electrically connected in sequence.

[0038] S2: While ensuring that the static elimination circuit is turned on or the static elimination circuit is overhauled, a standard parking position is designated for the vehicle. After the vehicle is parked at the designated position, the vehicle parking signal b is transmitted to the control system 13. The control system 13 controls the driving member 10 to drive the support seat 9 to move toward the static elimination contact plate 1 of the vehicle, so that the conductive head 2 contacts the static elimination contact plate 1 and moves. At the same time, the control system 13 receives the signal c of the pressure sensor 5. When the pressure value reaches the preset range as determined by the signal c, the controller controls the driving member 10 to stop driving. The spring 4 can ensure that the conductive head 2 is continuously turned on to the static elimination contact plate 1 to avoid power interruption in the middle.

[0039] S3: When the conductive head 2 stably contacts the vehicle's anti-static contact plate 1, the electrically conductive sensing element 12 determines the on-off signal a of the anti-static elimination circuit. If the signal a shows that the anti-static elimination circuit is on, the control system 13 indicates normal operation; if the signal a shows that the anti-static elimination circuit is off, the control system 13 instructs the vehicle to move away from the designated position in combination with the signal b; wherein the anti-static elimination circuit includes the anti-static contact plate 1 of the vehicle, the anti-static shaft 3, the first conductive block 6, the anti-static transmission wire 8, the electrically conductive sensing element 12, the grounding wire 11 and the control system 13, which are electrically connected in sequence; the entire process is used to monitor the entire electrostatic release process of the vehicle-borne material loading and unloading operation, monitor the working status and connection status of the anti-static elimination device in real time, and alarm if an abnormality is found, and record the relevant data for subsequent analysis and verification.

[0040] S4: When the vehicle can drive away, the control system 13 controls the driving member 10 to drive the support seat 9 to return to the initial position, and the conductive head 2 is completely separated from the static electricity removal contact plate 1 of the vehicle, completing the static electricity removal process of the vehicle.

[0041] In summary, the present invention proposes a vehicle static elimination device and method, and provides a new static elimination connecting joint, which is connected to the vehicle, which is conducive to realizing the automatic control of the vehicle static elimination process. The entire operation process of the vehicle static elimination device is automatically connected to the vehicle, and identifies, judges, and uses the static grounding release signal, avoiding manual operation of the corresponding device, which is conducive to supplementing the realization of the full process automation of vehicle-mounted material loading and unloading, reducing labor costs, and improving work efficiency; using advanced sensing technology and control system 13, it can accurately identify, judge, and control the static elimination process, ensuring that each operation can achieve the expected effect, and is not affected by human factors, and can maintain a stable working state in various environments, reducing errors and faults caused by improper operation; using the control system 13 to identify the static elimination process, and interlocking the static elimination signal with other operations through the control system 13, can effectively eliminate and avoid the safety risks of the vehicle-mounted material loading and unloading process.
