Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of heat dissipation for emulsion drilling rigs, and more specifically, to a rapid heat dissipation device for a highly stable emulsion drilling rig. Background Technology

[0002] In the field of emulsion drilling rigs, the cooling efficiency of the heat dissipation device directly affects the operational stability and continuous operation capability of the equipment. However, the existing cooling methods of emulsion drilling rigs generally rely on air cooling or natural cooling, which has technical defects such as low heat dissipation efficiency and inability to operate continuously for a long time, making it difficult to meet the high-efficiency production requirements of large-scale operation scenarios.

[0003] Traditional cooling methods suffer from significant structural defects: First, the heat dissipation mechanism is rudimentary, often employing an open-air cooling structure. Heat dissipation relies on forced convection via fans or natural cooling from the equipment casing, making its efficiency highly dependent on ambient temperature and airflow. In enclosed environments like underground mines, poor air circulation hinders heat dissipation during drilling, leading to decreased emulsion viscosity, deteriorated lubrication, and necessitating shutdown for cooling. Second, there is a lack of active cooling circulation design. Existing devices lack liquid cooling circulation or phase-change cooling structures, relying solely on heat exchange between the equipment and the air. This results in significant heat accumulation when the drilling load increases or operating time extends. For example, during hard rock drilling, the motors and pumps of emulsion drilling rigs generate substantial heat due to continuous high-load operation. Natural cooling cannot effectively remove this heat, causing critical components to overheat, leading to seal aging and accelerated bearing wear. Third, equipment utilization is limited. To avoid overheating damage, operators must use multiple drilling rigs alternately, increasing equipment procurement costs and requiring frequent shutdowns and switching, thus reducing operational efficiency.

[0004] Traditional cooling methods suffer from drawbacks such as outdated heat dissipation mechanisms, lack of active circulation, and low equipment utilization. When faced with scenarios such as deep hole drilling and high-intensity operations, they often lead to downtime due to untimely heat dissipation. There is an urgent need to develop new rapid heat dissipation devices with liquid cooling circulation and intelligent temperature control functions to improve the above-mentioned defects. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a rapid heat dissipation device for a highly stable emulsion drilling rig, which solves the technical defects of existing emulsion drilling rigs that generally rely on air cooling or natural cooling, resulting in low heat dissipation efficiency and inability to operate continuously for a long time, making it difficult to meet the high-efficiency production needs of large-scale operation scenarios.

[0006] According to one aspect, at least one embodiment of this disclosure provides a rapid heat dissipation device for a highly stable emulsion drilling rig, comprising:

[0007] The system includes a base plate, a water tank, and a drilling rig body, with the water tank fixed to the base plate and the drilling rig body mounted on the base plate.

[0008] The system includes a bottom cover, a top cover, and a protective heat dissipation assembly. The bottom cover is fixed to the surface of the base plate, the main body of the drilling rig is installed inside the bottom cover, the top cover is fixedly connected to the bottom cover by bolts, and the protective heat dissipation assembly is disposed in the bottom cover and the top cover.

[0009] A circulating cooling component is disposed in the water tank and the bottom cover;

[0010] The protective heat dissipation assembly includes a pair of cooling fans installed at the bottom of the base cover. A pair of air inlets are provided at the top of the top cover, and a filter screen is installed inside the air inlets. A fixing bracket is installed inside the base cover and is fitted onto the outside of the drilling rig body.

[0011] As a further technical solution, the circulating cooling component includes an inner cover, which is installed at the bottom inside the bottom cover and is located around the outer surface of the drilling rig body. A number of heat exchange plates are provided on the inner surface of the inner cover.

[0012] As a further technical solution, one end of the heat exchange plate is attached to the surface of the drilling rig body, and the other end of the heat exchange plate is located in the inner cover. The surface of the heat exchange plate located in the inner cover is provided with several through holes.

[0013] As a further technical solution, a baffle is provided inside the water tank, and a heat exchange tube is provided on the side surface of the baffle. One end of the heat exchange tube is a sealed structure, and a nitrogen tank is connected to one side of the water tank.

[0014] As a further technical solution, a circulating water pump is provided on the surface of the base plate. The suction end of the circulating water pump is connected to the water tank, and the water supply end of the circulating water pump passes through the bottom cover and is connected to the inner cover. One end of the bottom of the inner cover is connected to the water tank via a return pipe.

[0015] As a further technical solution, the heat exchange plate has an overall T-shaped structure, and the part of the heat exchange plate that fits into the drilling rig body has an arc-shaped transition structure.

[0016] As a further technical solution, the inner cover has an overall ring-shaped structure, and the bottom of the inner cover is a partition structure.

[0017] As a further technical solution, the inner end face of the air inlet has a stepped transition structure.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the protective heat dissipation component forms a protective shell through a bottom cover and a top cover. The cooling fan at the bottom of the bottom cover exhausts air downwards, and the air inlet of the top cover draws in air after being filtered by a filter screen, forming a heat dissipation airflow from top to bottom. The fixed bracket is fitted outside the drilling rig body, which not only supports the drilling rig but also forms an airflow channel to accelerate heat exchange. The filter screen intercepts dust and debris in the air to prevent internal contamination of the drilling rig. The bolt connection between the top cover and the bottom cover facilitates disassembly and maintenance. This component combines shell protection with air cooling, which effectively improves heat dissipation efficiency while ensuring the stability of the drilling rig operation, and solves the problem of low heat dissipation efficiency caused by existing devices relying solely on air cooling or natural cooling.

[0020] 2. In this disclosure, the circulating cooling component is wrapped around the outer periphery of the drilling rig body with an inner cover. One end of the heat exchange plate is attached to the heat source of the drilling rig, and the other end extends into the cavity of the inner cover. The through holes increase the contact area with the coolant. The circulating water pump delivers the coolant in the water tank to the inner cover. After flowing through the heat exchange plate to absorb the heat of the drilling rig, it returns to the water tank. The heat exchange tube in the water tank is connected to the nitrogen tank. The nitrogen pressure keeps the heat exchange tube at a low temperature, which exchanges heat with the circulating water in the water tank and keeps it at a low temperature. The heat exchange plate is made of a high thermal conductivity metal material and is combined with the annular flow channel of the inner cover to make the coolant absorb the heat of the drilling rig evenly. This component actively dissipates heat through liquid cooling circulation, which can effectively remove the heat generated by the operation of the drilling rig and avoid the deterioration of the emulsion or the wear of mechanical parts due to high temperature. It solves the problem that existing devices cannot be operated continuously for a long time and require multiple units to be used alternately. Attached Figure Description

[0028] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0029] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0030] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0034] like Figures 1-5 As shown, a rapid heat dissipation device for a high-stability emulsion drilling rig according to an embodiment of the present disclosure is illustrated, comprising:

[0035] The base plate 1, the water tank 2, and the drilling rig body 3 are provided. The water tank 2 is fixed on the base plate 1, and the drilling rig body 3 is mounted on the base plate 1.

[0036] The base cover 4, the top cover 5, and the protective heat dissipation component 6 are provided. The base cover 4 is fixed to the surface of the base plate 1. The drilling rig body 3 is installed inside the base cover 4. The top cover 5 is fixedly connected to the base cover 4 by bolts. The protective heat dissipation component 6 is provided in the base cover 4 and the top cover 5.

[0037] A circulating cooling component 7 is disposed in the water tank 2 and the bottom cover 4;

[0038] The protective heat dissipation component 6 includes a pair of cooling fans 6-1, which are installed at the bottom of the bottom cover 4. The top cover 5 has a pair of air inlets 6-2, and a filter screen 6-3 is installed inside the air inlets 6-2. A fixing bracket 6-4 is installed inside the bottom cover 4, and the fixing bracket 6-4 is fitted onto the outside of the drilling rig body 3.

[0039] In some examples, a protective heat dissipation assembly 6 is designed to protect the drilling rig body 3 and achieve air cooling. This assembly consists of a bottom cover 4 and a top cover 5 forming a protective shell. The cooling fan 6-1 at the bottom of the bottom cover 4 exhausts air downwards, allowing air to flow in from the air inlet 6-2 of the top cover 5 after being filtered by the filter screen 6-3, forming a top-to-bottom cooling airflow. The fixing bracket 6-4 is fitted onto the outside of the drilling rig body 3, providing support for the drilling rig and forming an airflow channel between the bracket and the drilling rig to accelerate heat exchange.

[0040] The filter 6-3 can intercept dust and debris in the air, preventing contamination of the internal components of the drilling rig. The bolted connection between the top cover 5 and the bottom cover 4 facilitates disassembly and maintenance. The cooling fan 6-1 can quickly remove the heat generated during the operation of the drilling rig, keeping the temperature of the main body 3 of the drilling rig within a safe range. Through the combination of shell protection and air cooling, the protective heat dissipation component 6 improves heat dissipation efficiency while ensuring the stability of the drilling rig operation.

[0041] like Figures 1-5 As shown in the figure, the circulating cooling component 7 in this embodiment includes an inner cover 7-1, which is installed at the bottom inside the bottom cover 4. The inner cover 7-1 is located around the outer surface of the drilling rig body 3. A plurality of heat exchange plates 7-2 are provided on the inner surface of the inner cover 7-1. One end of the heat exchange plate 7-2 is attached to the surface of the drilling rig body 3, and the other end of the heat exchange plate 7-2 is located in the inner cover 7-1. A plurality of through holes 7- are formed on the surface of the heat exchange plate 7-2 located in the inner cover 7-1. 3. A partition 7-4 is provided inside the water tank 2. A heat exchange tube 7-5 is provided on the side surface of the partition 7-4. One end of the heat exchange tube 7-5 is a sealed structure. A nitrogen tank 7-6 is connected to one side of the water tank 2. A circulating water pump 7-7 is provided on the surface of the bottom plate 1. The suction end of the circulating water pump 7-7 is connected to the water tank 2. The water supply end of the circulating water pump 7-7 passes through the bottom cover 4 and is connected to the inner cover 7-1. A return pipe 7-8 is connected to the bottom end of the inner cover 7-1 and the water tank 2.

[0042] In some examples, a circulating cooling component 7 is designed to achieve efficient water-cooled circulating cooling. This component encloses the drill body 3 with an inner cover 7-1. One end of a heat exchange plate 7-2 on the surface of the inner cover 7-1 is in contact with the drill's heat source, and the other end extends into the cavity of the inner cover 7-1. Through holes 7-3 on the heat exchange plate 7-2 increase the contact area with the coolant. A circulating water pump 7-7 delivers coolant (such as water or ethylene glycol solution) from the water tank 2 to the inner cover 7-1. After absorbing heat from the drill through the heat exchange plate 7-2, the coolant returns to the water tank 2 via a return pipe 7-8. The heat exchange tube 7-5 inside the water tank 2 is connected to a nitrogen tank 7-6. The nitrogen pressure generates a low temperature in the heat exchange tube 7-5, which exchanges heat with the circulating water in the water tank 2 to maintain the low temperature of the circulating water. The metal material of the heat exchange plate 7-2 has high thermal conductivity. Combined with the annular flow channel design of the inner cover 7-1, the coolant can evenly absorb the heat of the drilling rig. The heat dissipation area and circulation flow of the water tank 2 can be adjusted according to the power of the drilling rig. The temperature of the core components of the drilling rig is controlled through water cooling circulation to avoid the deterioration of the emulsion or wear of mechanical parts caused by high temperature, thus achieving a continuous and stable heat dissipation effect.

[0043] For example, such as Figure 5 As shown, the heat exchange plate 7-2 has an overall T-shaped structure, and the part of the heat exchange plate 7-2 that fits into the drilling rig body 3 has an arc-shaped transition structure.

[0044] In some examples, the T-shaped structure increases the contact area between the heat exchange plate 7-2 and the drilling rig body 3, thereby improving the heat exchange effect.

[0045] For example, such as Figure 5 As shown, the inner cover 7-1 has an overall ring-shaped structure, and the bottom of the inner cover 7-1 is a partition structure.

[0046] In some examples, the annular structure of the bottom partition ensures that the circulating water can only flow in one direction within the inner cover 7-1, thus ensuring heat exchange efficiency.

[0047] For example, such as Figure 5 As shown, the inner end face of the air inlet 6-2 has a stepped transition structure.

[0048] In some examples, the stepped structure allows the filter 6-3 to be embedded inside, making it easy to install, remove, and replace.

[0049] In actual use: the base plate 1 is fixed in a suitable position on the emulsion drilling rig, the water tank 2 is installed on the base plate 1, the drilling rig body 3 is placed on the base plate 1 and located inside the base cover 4, the base cover 4 is fixed to the surface of the base plate 1, the top cover 5 is connected to the base cover 4 by bolts, the cooling fan 6-1 of the protective heat dissipation component 6 is installed at the bottom of the base cover 4, the air inlet 6-2 of the top cover 5 is fitted with a filter screen 6-3, the inner fixing bracket 6-4 of the base cover 4 is fitted over the drilling rig body 3, the inner cover 7-1 of the circulating cooling component 7 is installed at the bottom inside the base cover 4 and surrounds the drilling rig body 3, one end of the heat exchange plate 7-2 is attached to the surface of the drilling rig body 3, and the other end is located in the inner cover. 7-1 has an opening 7-3 on its surface. A partition 7-4 and a heat exchange pipe 7-5 are installed inside the water tank 2. A nitrogen tank 7-6 is connected to the water tank 2. A circulating water pump 7-7 is installed on the base plate 1. Its suction end is connected to the water tank 2, and its water supply end passes through the bottom cover 4 and connects to the inner cover 7-1. The bottom of the inner cover 7-1 is connected to the water tank 2 through a return pipe 7-8. When in use, the cooling fan 6-1 runs to form an airflow from top to bottom to dissipate heat. The circulating water pump 7-7 pumps the coolant from the water tank 2 into the inner cover 7-1. The water flows through the heat exchange plate 7-2 to absorb the heat of the drilling rig and then returns to the water tank 2 through the return pipe 7-8. The nitrogen tank 7-6 cools the coolant in the water tank 2 through the heat exchange pipe 7-5.

[0050] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
