[0014] Each of the two energy storage battery compartments is provided with a cooling oil tank and a heating oil tank at both ends. A circulating oil tank is provided on one side of the heating oil tank. A circulating oil pump is fixedly installed on the top of the circulating oil tank.

[0020] Preferably, the energy storage drive control mechanism further includes a circuit control box disposed on the top of the vehicle body and a hydraulic pump station disposed inside the vehicle body. The hydraulic pump station, the energy storage battery pack, the temperature sensor, the circulating oil pump, the electric heating rod, and the plurality of solenoid valves are all electrically connected to the circuit control box via cables.

[0021] The hydraulic pump station is used to provide hydraulic drive for the hydraulic working arm and the tunnel operation module mounted on the vehicle body surface.

[0022] The surface of the vehicle body is provided with a hydraulic oil circuit access module, which is composed of multiple mechanical quick-connect couplings. The hydraulic oil circuit access module is connected to the hydraulic pump station through oil pipes.

[0023] The circuit control box is electrically connected to the positive and negative copper rings via cables. The circuit control box contains a power conversion module, a power distribution control module, an intelligent control module, and a human-machine interaction module. The power conversion module is a bidirectional DC-DC converter. The power distribution control module consists of three main circuit AC contactors. The intelligent control module is a single-level PLC controller. The human-machine interaction module is an industrial touch screen electrically connected to the single-level PLC controller via cables.

[0024] Preferably, a method for controlling energy consumption of tunnel new energy operation equipment is characterized by comprising the following steps:

[0025] Step 1: Establish a dual power supply and rotary power supply architecture. Connect the external cable inside the electric telescopic arm to the power grid inside the tunnel to establish a fixed power supply; establish a mobile power supply through the vehicle-mounted energy storage battery pack; and use a rotary drive power supply mechanism to realize the continuous transmission of electrical energy from the chassis to the upper body. This mechanism includes positive and negative conductive copper channels fixed on the chassis and positive and negative electrical contact copper rings installed on the vehicle body. The uninterrupted supply of electrical energy is realized when the vehicle body rotates 360° through sliding contact.

[0026] Step 2: Implement multi-mode intelligent power switching control. Based on the intelligent decision-making of the primary PLC controller, the three main circuit AC contactors are used to realize the automatic switching of three working modes. When the "grid operation" mode is selected, the primary PLC controller controls KM1 to engage, and the grid power directly drives the hydraulic pump station and the crawler drive motor load.

[0027] When the "energy storage battery pack charging" mode is selected, the first-level PLC controller controls KM2 to engage, and the grid power is converted into DC power by the bidirectional DC-DC converter to charge the battery;

[0028] When the "pure energy storage battery pack operation" mode is selected, the first-level PLC controller controls the KM3 to engage, and the battery power is inverted into AC power by the bidirectional DC-DC converter to drive the equipment.

[0029] Step 3: Implement intelligent thermal management control for the battery pack. Temperature sensors located within the energy storage battery compartment monitor the battery temperature in real time, and the following controls are executed based on decisions made by the primary PLC controller:

[0030] When the battery temperature is lower than the set lower limit, the electric heating rod is activated to heat the heat transfer oil in the heating oil tank. At the same time, the circulating oil pump and the corresponding solenoid valve are controlled to make the hot oil flow through the metal heat transfer oil pipe on the surface of the battery pack for circulation heating.

[0031] When the battery temperature exceeds the set upper limit, the system switches to the cooling oil circuit, allowing the low-temperature heat-conducting oil in the cooling oil tank to flow through the battery pack and absorb heat. The heat is then dissipated into the environment through metal heat sinks with polygonal heat dissipation holes.

[0032] When the battery temperature is within the normal range, keep the thermal management system in standby mode.

[0033] Step 4: Implement coordinated energy distribution control for the entire machine, and uniformly schedule the energy-consuming units of the equipment through a primary PLC controller:

[0034] Power is dynamically allocated to the drive motor, rotary drive geared motor, and hydraulic pump station of the tracked chassis according to the construction conditions; the energy consumption of each branch is monitored in real time through current sensors to optimize power output; and the switching strategy between grid power supply and battery power supply is intelligently planned based on the construction plan and workload prediction to maximize the use of off-peak electricity prices and reduce construction operation costs.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. By incorporating an energy storage drive control mechanism and a rotating conductive mechanism, the equipment achieves seamless switching between direct grid power and battery power modes, as well as 360° continuous rotation operation, fundamentally eliminating exhaust gas pollution inside the tunnel. It also features zero emissions, low noise, and high energy utilization, significantly reducing direct electricity costs and ventilation energy consumption, resulting in overall energy savings and providing a new green and efficient equipment solution for tunnel construction.

[0037] 2. By setting up energy consumption control methods, the operating cost of the equipment is reduced compared with traditional fuel-powered equipment. Electricity expenses are reduced through off-peak charging and intelligent scheduling, further reducing operating costs. At the same time, zero-emission construction is achieved in the tunnel, completely eliminating the harmful exhaust gas generated by diesel equipment. During tunnel construction, the need for large-scale ventilation to dilute diesel exhaust gas is eliminated, which also reduces the energy consumption of the ventilation system. This effectively solves the technical problems of high energy consumption and high pollution of tunnel construction equipment, providing reliable equipment support for green tunnel construction.

[0038] 3. By setting up an energy storage drive control mechanism, the operating temperature of the energy storage battery pack is kept within the optimal range through the circulating oil pump, cooling oil tank, and heating oil tank during use, thereby extending the service life of the energy storage battery pack.

[0081] By setting up an energy storage drive control mechanism, during use, the operating temperature of the energy storage battery pack 701 is always kept within the optimal range through the circulating oil pump 705, cooling oil tank 702, and heating oil tank 703, thereby extending the service life of the energy storage battery pack 701 by more than 30%.

[0082] Furthermore, the working principle is as follows: This operating equipment adopts a dual power supply drive. One power source is directly connected to the tunnel power grid through the external cable 3 inside the electric telescopic arm 2; the other is the vehicle-mounted energy storage battery pack 701. Electrical energy is introduced into the vehicle body 4 through a rotary drive power supply mechanism.

[0083] Specifically, the positive conductive copper channel 603 and negative conductive copper channel 604 on the circular load-bearing plate 6 are connected to the external power grid and the drive motor of the tracked chassis 1 via cables. At the bottom of the vehicle body 4, positive and negative conductive copper rings 610 and 611 are installed in sliding contact with the insulating ceramic contact ring, so that when the vehicle body 4 rotates 360 degrees, electrical energy can still be continuously and stably transmitted from the chassis to all systems in the upper vehicle body 4.

[0084] Secondly, the power conversion module, with a bidirectional DC-DC converter at its core, converts AC power from the grid to DC power to charge the energy storage battery pack 701 when powered by external cable 3; and converts the battery DC power to AC power to drive the motor when powered by the energy storage battery pack 701. Power switching is achieved through three main circuit AC contactors in the power distribution control module. Specifically, KM1 is responsible for connecting the grid to loads such as the hydraulic pump station 718 (direct grid supply); KM2 is responsible for connecting the grid to the bidirectional DC-DC converter (grid charging); and KM3 is responsible for connecting the battery to the bidirectional DC-DC converter (battery power supply). These three components are interlocked through hardware and software to prevent misoperation.

[0085] During power switching and control, an intelligent control module is used. The intelligent control module is based on a single-level PLC controller. It collects signals from the mode selection switch, data from various voltage / current sensors and temperature sensors, as well as the status of the emergency stop button. It then makes logical judgments to drive the corresponding contactor to operate and precisely control the working mode and output of the bidirectional DC-DC converter.

[0086] Finally, during equipment operation, the power supply switching control is performed through the human-machine interface module. Specifically, the industrial touchscreen provides the operator with information such as equipment status, battery level, and fault alarms, and receives operation commands. After the operator selects the working mode through the human-machine interface, the primary PLC controller automatically controls the on / off state of the contactor. For example, when "grid operation" is selected, KM1 is engaged, and the grid directly drives the equipment.

[0087] When "Storage Battery Pack 701 Charging" is selected, KM2 engages, and the grid charges the battery through the converter;

[0088] When "Pure Energy Storage Battery Pack 701 Operation" is selected, KM3 engages, and the energy storage battery pack 701 supplies power to the equipment through the converter. The power supply and control of the rotary drive geared motor 608 are controlled and managed by a primary PLC controller. By driving the drive gear 609 on its output shaft, it meshes with the driven gear ring 607 on the vehicle body 4, achieving precise rotation of the vehicle body 4.

[0089] Meanwhile, to ensure the efficient and safe operation of the core component, the energy storage battery pack 701, in the harsh environment of the tunnel, the equipment integrates an intelligent thermal management system. Temperature sensors in the two energy storage battery compartments 7 monitor the battery temperature in real time. When the temperature is too low, the primary PLC controller starts the circulating oil pump 705, opens the solenoid valve on the pipeline leading to the heating oil tank 703, and activates the electric heating rod 710 to heat the heat transfer oil. The warm oil flows through the metal heat transfer oil pipe 714 surrounding the battery to heat the battery. When the temperature is too high, the primary PLC controller switches the oil circuit to the cooling oil tank 702. After flowing through the battery, the low-temperature heat transfer oil transfers heat to the metal heat sink 711 with polygonal heat dissipation holes inside the oil tank. The large-area heat dissipation of the metal heat sink 711 effectively cools the battery.

[0090] Under the unified scheduling of the primary PLC controller, electrical energy is precisely allocated to the drive motor of the tracked chassis 1, the rotary drive geared motor 608, and the hydraulic pump station 718 that provides power to the hydraulic working arm 5 and the tunnel operation module. This drives the equipment to complete various construction tasks such as anchor drilling and installation in the tunnel, achieving green and intelligent construction with zero emissions, low noise, and high energy efficiency.

[0091] A method for controlling energy consumption of new energy operation equipment in tunnels includes the following steps:

[0092] Step 1: Establish a dual-power supply and rotary power supply architecture. A fixed power source is established by connecting the external cable 3 inside the electric telescopic arm 2 to the tunnel's power grid; a mobile power source is established through the onboard energy storage battery pack 701. A rotary drive power supply mechanism is used to achieve continuous power transmission from the chassis to the upper body 4. This mechanism includes positive and negative conductive copper channels 604 fixed on the chassis and positive and negative contact copper rings 611 installed on the body 4. Uninterrupted power supply is achieved during the 360° rotation of the body 4 through sliding contact.

[0093] Step 2: Implement multi-mode intelligent power switching control. Based on the intelligent decision-making of the primary PLC controller, the three working modes are automatically switched through three main circuit AC contactors (KM1, KM2, KM3). When the "grid operation" mode is selected, the primary PLC controller controls KM1 to engage, and the grid power directly drives the hydraulic pump station 718, crawler drive motor and other loads.

[0094] When the "energy storage battery pack 701 charging" mode is selected, the first-level PLC controller controls KM2 to engage, and the grid power is converted into DC power by the bidirectional DC-DC converter to charge the battery.

[0095] When the "Pure Energy Storage Battery Pack 701 Operation" mode is selected, the first-level PLC controller controls KM3 to engage, and the battery power is inverted into AC power by the bidirectional DC-DC converter to drive the equipment.

[0096] Step 3: Implement intelligent thermal management control for the battery pack. Temperature sensors located within the energy storage battery compartment 7 monitor the battery temperature in real time. Based on decisions made by the primary PLC controller, the following controls are executed:

[0097] When the battery temperature is lower than the set lower limit, the electric heating rod 710 is activated to heat the heat transfer oil in the heating oil tank 703. At the same time, the circulating oil pump 705 and the corresponding solenoid valve are controlled to make the hot oil flow through the metal heat transfer oil pipe 714 on the surface of the battery pack for circulating heating.

[0098] When the battery temperature exceeds the set upper limit, the system switches to the cooling oil circuit, allowing the low-temperature heat-conducting oil in the cooling oil tank 702 to flow through the battery pack and absorb heat. The heat is then dissipated into the environment through the metal heat sink 711 with polygonal heat dissipation holes.

[0099] When the battery temperature is within the normal range, keep the thermal management system in standby mode.

[0100] Step 4: Implement coordinated energy distribution control for the entire machine, and uniformly schedule the energy-consuming units of the equipment through a primary PLC controller:

[0101] Power is dynamically allocated to the drive motor, rotary drive geared motor 608, and hydraulic pump station 718 of the tracked chassis 1 according to the construction conditions; the energy consumption of each branch is monitored in real time through current sensors to optimize power output; based on the construction plan and workload prediction, the switching strategy between grid power supply and battery power supply is intelligently planned to maximize the use of off-peak electricity prices and reduce construction operation costs.

[0102] By implementing energy consumption control methods, operating costs are reduced by more than 40% compared to traditional fuel-powered equipment. Electricity expenses are further reduced through off-peak charging and intelligent scheduling, further lowering operating costs. Simultaneously, zero-emission construction within the tunnel is achieved, completely eliminating harmful exhaust gases from diesel equipment. During tunnel construction, the elimination of the need for extensive ventilation to dilute diesel exhaust gases also reduces the energy consumption of the ventilation system by 50%-70%. This effectively solves the technical challenges of high energy consumption and high pollution in tunnel construction equipment, providing reliable equipment support for green tunnel construction.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
