Description

Technical Field

[0001] The utility model relates to the technical field of telescopic arm type hydraulic sandblasting cutting devices, and more specifically to an internal cooling device for equipment operating in a high-temperature environment. Background Art

[0002] In existing technology, telescopic-arm hydraulic sandblasting cutting devices are used to hydraulically cut burning wellhead equipment in the event of an oil and gas field fire. A single cutting operation typically takes more than 30 minutes. When an oil and gas well blowout occurs, the core temperature of the wellhead flame can reach 1500°C, generating significant heat radiation around the wellhead. Operation of the equipment typically requires multiple fire trucks to simultaneously spray high-pressure water to suppress the fire source and cool the equipment surface. However, due to variable wind direction and the presence of downtime between water supply changes, the temperature of the equipment itself often exceeds the ambient temperature. The hydraulic sandblasting cutting device is powered by a lithium battery, and the crawler hydraulic system is driven by a synchronous motor. The equipment contains multiple electrical devices and control systems, requiring an internal ambient temperature no higher than 50°C. Heat generated by the power and electrical systems within the equipment must be dissipated promptly to prevent downtime and equipment damage from overheating.

[0003] In summary, how to effectively cool down the interior of a mobile device operating in a high-temperature environment is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide an internal cooling device for equipment operating in a high-temperature environment, which can effectively cool the interior of equipment operating in a mobile manner in a high-temperature environment.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] An internal cooling device for equipment operating in a high-temperature environment, comprising:

[0007] chassis assembly;

[0008] a working chamber, which is provided at the front end of the platform of the chassis assembly, the working chamber being covered with a cover to isolate it from the external high-temperature environment, and the working chamber being provided with a water pump, a motor, a controller for controlling the operation of the motor, a battery, and a radiator;

[0009] a water storage tank disposed at the rear end of the platform, wherein a first tubular heat exchanger is disposed in the water storage tank, the first tubular heat exchanger is connected to an external circulating cold water tank, the water outlet of the first tubular heat exchanger, the motor, the radiator, the water pump, and the water return port of the first tubular heat exchanger are sequentially connected via pipelines, the water outlet of the first tubular heat exchanger, the battery, the radiator, the water pump, and the water return port of the first tubular heat exchanger are sequentially connected via pipelines, the water outlet of the first tubular heat exchanger, the controller, the radiator, the water pump, and the water return port of the first tubular heat exchanger are sequentially connected via pipelines;

[0010] A fan is provided on one side of the radiator and is used to take away the heat in the working chamber space.

[0011] In one embodiment, the platform is filled with thermal insulation wool.

[0012] In one embodiment, the inner wall of the cover is provided with heat insulating cotton.

[0013] In one embodiment, the joint surface between the cover and the platform is sealed by an insulating tape.

[0014] In one embodiment, the cover is provided with an openable and closable movable door, and the frame of the movable door and the cover are sealed and connected via an insulating belt.

[0015] In one embodiment, it also includes a travel motor for driving the chassis assembly to travel, a hydraulic oil tank for supplying oil to the travel motor, and a hydraulic pump for pumping hydraulic oil from the hydraulic oil tank into the travel motor, and the hydraulic pump is arranged between the hydraulic oil tank and the travel motor.

[0016] In one embodiment, a second tubular heat exchanger is further provided in the water storage tank, and the second tubular heat exchanger is connected to the external circulating cold water tank. The water outlet of the second tubular heat exchanger, the hydraulic oil tank, the hydraulic pump, the travel motor and the return water outlet of the second tubular heat exchanger are connected in sequence through pipelines.

[0017] In one embodiment, an overflow valve is provided on the top of the water storage tank.

[0018] In one embodiment, temperature sensors are provided in the water storage tank, the working chamber and each of the pipes for circulating cold water. The temperature sensors, the water pump and the fan are all connected to a control device.

Furthermore, a water pump is installed within the working chamber. Pipes connect the electrical equipment (such as the motor, controller, and battery), the radiator, and a first tubular heat exchanger within the water tank to form a closed circulating coolant circuit. This circuit carries heat generated by the electrical equipment and heat from the working chamber to the water tank, where it is then transferred to the external circulating water within the tank via the first tubular heat exchanger. In other words, heat generated by the electrical equipment is transferred through the coolant flowing within the circulating circuit, and then transferred to the cooling water within the tank via the first tubular heat exchanger. The equipment only needs to replenish the external circulating cooling water to effectively dissipate heat generated by the electrical equipment and heat transferred from the external environment in a timely manner, ensuring that the temperature within the equipment, even when operating continuously in a high-temperature environment, does not exceed the permitted operating ambient temperature.

[0022] In summary, the internal cooling device for equipment operating in a high-temperature environment provided by the present invention can achieve effective cooling of the interior of equipment operating in a mobile manner in a high-temperature environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] The core of the utility model is to provide an internal cooling device for equipment operating in a high-temperature environment, which can effectively cool the interior of mobile equipment operating in a high-temperature environment.

[0030] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the internal cooling device of the equipment operating in a high-temperature environment provided by the present invention, viewed from a top perspective; Figure 2 This is a schematic structural diagram from a top view of another embodiment of an internal cooling device for equipment operating in a high-temperature environment.

[0031] This specific embodiment provides a device for cooling the interior of a device operating in a high-temperature environment, comprising:

[0032] chassis assembly;

[0033] A working chamber 1 is provided at the front end of the platform of the chassis assembly. The working chamber 1 is covered with a cover 2 to isolate it from the external high-temperature environment. The working chamber 1 is provided with a water pump 3, a motor 4, a controller 5 for controlling the operation of the motor 4, a battery 6, and a radiator 7.

[0034] A water storage tank 8 is provided at the rear end of the platform. A first tubular heat exchanger 9 is provided in the water storage tank 8. The first tubular heat exchanger 9 is connected to an external circulating cold water tank 15. The water outlet of the first tubular heat exchanger 9, the motor 4, the radiator 7, the water pump 3 and the water return port of the first tubular heat exchanger 9 are sequentially connected through pipelines. The water outlet of the first tubular heat exchanger 9, the battery 6, the radiator 7, the water pump 3 and the water return port of the first tubular heat exchanger 9 are sequentially connected through pipelines. The water outlet of the first tubular heat exchanger 9, the controller 5, the radiator 7, the water pump 3 and the water return port of the first tubular heat exchanger 9 are sequentially connected through pipelines.

[0035] The fan 10 is provided on one side of the radiator 7 and is used to remove heat from the working chamber 1 .

[0036] It should be noted that to ensure that the temperature within the equipment's interior does not exceed the ambient temperature permitted for operation during continuous operation, it is necessary to minimize the transfer of heat from the external environment into the equipment and promptly dissipate the heat generated by the electrical equipment within the equipment. A radiator 7 (e.g., a copper tube finned radiator 7) is positioned within the working chamber 1. Ventilation is provided by a fan 10, which exchanges heat between the coolant flowing through the radiator 7 tubes and the external air, removing heat from the space. A water pump 3 is also positioned within the working chamber 1. Pipes connect the electrical equipment, the radiator 7, and a first tubular heat exchanger 9 (e.g., a copper tube heat exchanger) within a water tank 8, forming a closed circulating coolant circuit. This circuit brings heat generated by the electrical equipment and heat from the platform space into the water tank 8, where it is transferred via the first tubular heat exchanger 9 to the external circulating water within the water tank 8.

[0037] It should also be noted that the present application is configured in this way, which has the following advantages compared to the existing method of directly using an external water source for circulating cooling: First, the pipeline connection of the present application is a closed connection, which ensures the cleanliness of the pipeline and is not prone to blockage, and antifreeze can be used as a coolant, so that the equipment does not need to worry about draining water or freezing when stored in an environment below 0°C; second, it can prevent the pressure fluctuations and flow changes of the external water source from causing adverse effects on internal cooling; third, for mobile equipment, if the connecting pipeline of the external circulating cold water tank 15 breaks during movement or suddenly cannot supply water, the equipment in a high temperature environment will face the risk of being damaged, and the internal cooling design of the present application is equipped with a water storage tank 8. Even if the external water source suddenly cannot supply water, the water stored in the water storage tank 8 can absorb heat and cool down, ensuring that the equipment has enough time to be modified or evacuated from the high temperature site.

[0038] During actual use, the shape, structure, size, material, position, etc. of the chassis assembly, working chamber 1, cover 2, water tank 8, first tubular heat exchanger 9, motor 4, radiator 7 and water pump 3 can be determined according to actual conditions and actual needs.

[0039] When using the internal cooling device of the equipment operating in a high-temperature environment provided by the present invention, the chassis assembly is used to realize the spatial movement of the device. The working chamber 1 is covered with a cover 2 to form an insulating space that is relatively closed to the external high-temperature environment. Therefore, in a high-temperature environment, the heat transferred from the external environment to the inside of the equipment can be effectively reduced. Reducing the heat transferred in helps to achieve internal cooling of the equipment and avoid accumulated temperature rise in the equipment. Moreover, a water tank 8 is provided at the rear end of the platform of the chassis assembly. A first tubular heat exchanger 9 is arranged inside the water tank 8. The first tubular heat exchanger 9 is connected to an external circulating cold water tank 15 to ensure that the water tank 8 is always filled with cooling water. The cooling water can take away the heat of the circulating coolant in the first tubular heat exchanger 9.

[0040] Furthermore, a radiator 7 is installed within the working chamber 1. Ventilated by a fan 10, the coolant flowing through the radiator 7 tubes exchanges heat with the external air, removing heat from the space and lowering the temperature of the equipment within the working chamber 1. Furthermore, a water pump 3 is positioned within the working chamber 1. Through piping, the electrical equipment (such as the motor 4, controller 5, and battery 6) is connected to the radiator 7 and a first tubular heat exchanger 9 within a water tank 8 to form a closed circulating coolant circuit. This circuit carries heat generated by the electrical equipment and heat from the working chamber 1 into the water tank 8, where it is then transferred to the external circulating water within the water tank 8 via the first tubular heat exchanger 9. In other words, the heat generated by the electrical equipment is transferred through the coolant flowing within the circulating circuit, and then transferred to the cooling water within the water tank 8 via the first tubular heat exchanger 9. The equipment only needs to replenish the external circulating cooling water to effectively dissipate the heat generated by the electrical equipment and heat transferred from the external environment in a timely manner, ensuring that the temperature within the equipment, which operates continuously in a high-temperature environment, does not exceed the ambient temperature allowed for operation.

[0041] In summary, the internal cooling device for equipment operating in a high-temperature environment provided by the present invention can achieve effective cooling of the interior of equipment operating in a mobile manner in a high-temperature environment.

[0042] In one embodiment, the platform is filled with thermal insulation cotton, that is, the space at the bottom of the platform can be filled with thermal insulation cotton with extremely low thermal conductivity, which helps to form a relatively closed and insulated space from the external high-temperature environment.

[0043] In one embodiment, the inner wall of the cover 2 is provided with heat-insulating cotton so as to make the working chamber 1 a heat-insulating space that is relatively closed from the external high-temperature environment.

[0044] In one embodiment, the interface between the cover 2 and the platform is sealed by an insulating tape, that is, the interface between the cover 2 and the platform can use the insulating tape as a sealing material to form a relatively closed and heat-insulated space from the external high-temperature environment.

[0045] In one embodiment, the cover 2 is provided with a movable door that can be opened and closed. The frame of the movable door is sealed to the cover 2 by an insulating tape. In other words, the insulating tape can be used as a sealing material at the door opening of the cover 2, thereby forming a relatively isolated and insulated space from the external high-temperature environment.

[0046] In one embodiment, it also includes a travel motor 11 for driving the chassis assembly to travel, a hydraulic oil tank 12 for supplying oil to the travel motor 11, and a hydraulic pump 13 for pumping hydraulic oil from the hydraulic oil tank 12 into the travel motor 11. The hydraulic pump 13 is arranged between the hydraulic oil tank 12 and the travel motor 11.

[0047] In one embodiment, Figure 2 As shown, a second tubular heat exchanger 14 is also provided within the water tank 8. This second tubular heat exchanger 14 is connected to an external circulating cold water tank 15. The outlet of the second tubular heat exchanger 14, the hydraulic oil tank 12, the hydraulic pump 13, the travel motor 11, and the return port of the second tubular heat exchanger 14 are sequentially connected via pipelines. In other words, the return oil pipeline of the equipment's hydraulic system is connected to the second tubular heat exchanger 14 within the water tank 8 and then back to the hydraulic oil tank 12. During operation, the heat generated by the hydraulic oil is transferred to the circulating water within the water tank 8 via the second tubular heat exchanger 14. The pipelines connected to the second tubular heat exchanger 14 are used to transport hydraulic oil and may also be referred to as hydraulic oil pipelines 17. The pipelines connected to the first tubular heat exchanger 9 are used to transport coolant (i.e., circulating cold water) and may also be referred to as coolant pipelines 16.

[0048] In one embodiment, an overflow valve is provided at the top of the water tank 8, that is, the top of the water tank 8 overflows to ensure that the inside of the water tank 8 is always filled with water, so as to facilitate the removal of heat from the circulating coolant in the first tubular heat exchanger 9 and the second tubular heat exchanger 14.

[0049] In one embodiment, temperature sensors are provided in the water storage tank 8, the working chamber 1 and each pipe for circulating cold water. The temperature sensors, the water pump 3 and the fan 10 are all connected to the control device.

[0050] It should be noted that temperature sensors can be installed in the water tank 8, the working chamber 1 and each pipeline. The temperature sensors are used to monitor the temperature of the equipment in real time during operation, and can effectively adjust the temperature inside the working chamber 1 by adjusting the amount of external circulating water.

[0051] In one embodiment, all pipelines are hoses, so as to achieve internal cooling of the equipment when the equipment is fixed or moved in a high temperature environment, and avoid the pipeline connection from being disconnected.

[0052] It should be noted that the present application forms an insulating space on the platform of the chassis assembly that is relatively closed to the external environment; the heat generated by the electrical equipment and the heat in the platform space are all transferred to the water tank 8 connected to the external circulating cold water tank 15 (external water source) through the flow of coolant in the closed circulation pipeline inside the working chamber 1, and the heat is transferred to the cooling water in the water tank 8 through the first tubular heat exchanger 9; the water tank 8 is connected to the external circulating cold water to take away the heat.

[0053] It should be noted that the first tubular heat exchanger 9 and the second tubular heat exchanger 14 mentioned in the present invention are only used to distinguish the difference in position and there is no order of precedence.

[0054] In addition, it should be noted that the directions or positional relationships indicated by "front and back", "in and out", etc. in the present invention are based on the directions or positional relationships shown in the accompanying drawings, and are only for the purpose of simplifying the description and facilitating understanding, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

The same or similar parts between the various embodiments can be referenced to each other.

The description of the above embodiments is only used to help understand the method and core ideas of the present invention.
