Description

Technical Field

[0001] The utility model relates to the technical field of water tank antifreeze of automobile drilling rigs, in particular to a water tank antifreeze system of an automobile drilling rig and the automobile drilling rig. Background Art

[0002] Mobile drilling rigs are automobile-based drilling equipment, offering the advantages of flexibility, maneuverability, speed, and convenience. They are particularly widely used in northern my country. They are equipped with a water tank for drilling, eliminating the need to locate water near the drilling site, as with crawler drilling rigs. This significantly reduces the difficulty of finding water in the field. However, in northern China, such as Inner Mongolia and Northeast China, winter temperatures can reach -30°C, and drilling operations often take place outdoors. In these conditions, the water stored in the tank can freeze and become unusable, significantly impacting drilling efficiency.

[0003] The current common practice is to use oxyacetylene welding to bake the water tank to solve this problem. First, this method is time-consuming and labor-intensive, and carries certain safety risks. Second, once the water inside the water tank freezes, this ice-melting operation must be repeated before each drilling operation, which slows down the construction progress.

[0004] There are also existing technologies that address the antifreeze problem of ordinary automobile water tanks. They propose a solution that utilizes the waste heat of the engine system and cooperates with an electric heating system to continuously heat the automobile water tank. Although the waste heat of the engine is utilized, the water in the water tank is not flowing, and the heat exchange efficiency is low. In addition, the addition of the electric heating system also requires additional energy consumption, which is not economical. Utility Model Content

[0031] The following combination Figure 1-Figure 2 The utility model describes a water tank antifreeze system for an automobile drilling rig and the automobile drilling rig.

[0032] Figure 1 This is a structural diagram of the antifreeze system of the automobile drilling rig provided by the utility model, such as Figure 1 As shown, the utility model provides a water tank antifreeze system for an automobile drilling rig, comprising: a water tank 1, a first water pipe 2, a second water pipe 3, a water pump 4 and a heat exchanger 5;

[0033] The water inlet of the first water pipe 2 is connected to the water tank 1, and the water outlet of the first water pipe 2 is connected to the heat exchanger 5; the water inlet of the second water pipe 3 is connected to the heat exchanger 5, and the water outlet of the second water pipe 3 is connected to the water tank 1; a water pump 4 is provided on the first water pipe 2, and is used to provide power for the water circulation between the water tank 1 and the heat exchanger 5; the heat exchanger 5 is connected to the engine antifreeze circulation device 6 of the automobile drilling rig, and is used to provide a heat source for the heat exchanger 5;

[0034] The water tank 1 further includes a water inlet 7 and a water intake 8; the water inlet 7 is used to add water to the water tank 1, and the water intake 8 is used for the automobile drilling rig to take water from the water tank 1.

[0035] In one embodiment of the present invention, the heat exchanger 5 can adopt a plate heat exchanger 5, the material of which is copper, and the heat transfer method is partition heat transfer. The specifications of BR0.05~0.23 can be adopted. A partition is set inside the heat exchanger 5 to divide the internal space of the heat exchanger 5 into two chambers while serving as a medium for heat transfer. One of the chambers of the heat exchanger 5 is used to receive the heat source, and the other chamber is used to output heat; in addition, the water pump 4 can adopt a miniature high-temperature resistant DC water pump 4 powered by DC 12V, with a head of 2.0m. There are many mature products on the market, and basically all of them can be adopted.

[0036] According to an embodiment of the present invention, a water tank antifreeze system for an automobile drilling rig is provided. The water tank 1 is a water heater shell. The capacity of the water tank 1 is between 300L and 1200L. Specifically, a large-capacity water heater of 500L or 1000L can be used.

[0037] Specifically, water tank 1 primarily stores drilling water for the drilling rig. Using a large-capacity, old electric water heater as water tank 1 allows for cost-effective waste recycling. Before using the old electric water heater as water tank 1, the electric heating plate must be removed and inspected to ensure the inner tank remains usable. Before the mobile drilling rig departs for operations, water tank 1 can be filled with hot water. Because the old electric water heater itself has an insulation layer, it effectively insulates the water in tank 1, minimizing the drop in water temperature.

[0038] According to an embodiment of the present invention, a water tank antifreeze system for an automobile drilling rig is provided, wherein the outer walls of the first water pipe 2 and the second water pipe 3 are both provided with a thermal insulation layer, which can reduce the heat loss of water during the circulation process;

[0039] Specifically, the first water pipe 2 and the second water pipe 3 can be made of polyurethane insulation hose, which itself has insulation function. Ordinary pipes can be used and a layer of insulation material can be wrapped on the pipe wall surface, such as bonding or tying insulation cotton.

[0040] According to an embodiment of the present invention, a water tank antifreeze system for an automobile drilling rig is provided, wherein the outer diameters of the first water pipe 2 and the second water pipe 3 are between 40 mm and 80 mm, and the wall thicknesses are both between 3.5 mm and 5 mm;

[0041] Specifically, in one embodiment of the present invention, the outer diameters of the first water pipe 2 and the second water pipe 3 are both 60 mm, and the wall thicknesses are both 4.2 mm; the specifications of the first water pipe 2 and the second water pipe 3 may also not be restricted, and water pipes with larger or smaller diameters may be selected according to the actual demand for water circulation volume.

[0042] According to an embodiment of the present invention, a water tank antifreeze system for a vehicle drilling rig further includes a warm air water pipe 9;

[0043] The warm air water pipe 9 includes a warm air water inlet pipe 91 and a warm air water return pipe 92; the water inlet of the warm air water inlet pipe 91 is connected to the engine antifreeze circulation device 6, and the water outlet of the warm air water inlet pipe 91 is connected to the heat exchanger 5; the water inlet of the warm air return pipe 92 is connected to the heat exchanger 5, and the water outlet of the warm air return pipe 92 is connected to the engine antifreeze circulation device 6;

[0044] Specifically, in one embodiment of the present invention, the warm air water pipe 9 can be made of a polyurethane insulated hose, and the water outlet of the warm air inlet pipe 91 and the water inlet of the warm air return pipe 92 are connected to the same chamber of the heat exchanger 5, that is, the chamber used to receive the heat source; the antifreeze that has absorbed the heat of the engine flows into the chamber of the heat exchanger 5 used to receive the heat source through the warm air inlet pipe 91, brings the heat to the partition wall, and then flows back to the engine antifreeze circulation device 6 through the warm air return pipe 92 to complete the heat supply.

[0045] According to an embodiment of the utility model, a water tank antifreeze system for an automobile drilling rig is provided, which also includes a solenoid valve 10. The solenoid valve 10 is arranged on the warm air inlet pipe 91. The solenoid valve 10 is a switch type and can be purchased directly on the market; the solenoid valve 10 controls whether water flows through the warm air inlet pipe 91. When the solenoid valve 10 is closed, the engine antifreeze circulation device 6 performs internal circulation, and the generated warm air enters the cab; when the solenoid valve 10 is opened, the antifreeze in the engine antifreeze circulation device 6 flows into the warm air inlet pipe 91, and then enters the antifreeze system of the water tank 1, and no longer provides warm air for the cab.

[0046] According to an embodiment of the present invention, a water tank antifreeze system for an automobile drilling rig is provided, wherein the outer diameter of the warm air water pipe 9 is between 20 mm and 60 mm, and the wall thickness is between 2.5 mm and 4 mm;

[0047] Figure 2 This is a structural diagram of an antifreeze system for a car drilling rig provided by one embodiment of the present utility model. Figure 2 As shown, specifically, in a specific embodiment of the present invention, the outer diameter of the warm air water pipe 9 is 40 mm and the wall thickness is 3.2 mm; wherein, multiple warm air water pipes 9 can be arranged according to actual needs, which can improve the heat exchange efficiency. At this time, the heat exchanger 5 and the warm air water pipe 9 are in parallel.

[0048] According to an embodiment of the present invention, a water tank antifreeze system for a vehicle drilling rig is provided, further comprising a sensor 11 and a display assembly 12; the sensor 11 is disposed below the water surface inside the water tank 1 and is used to monitor the temperature and / or water level; the display assembly 12 is disposed in the cab of the vehicle drilling rig and is electrically connected to the sensor 11 via a connecting line 13; wherein the display assembly 12 is used to display the temperature and / or water level;

[0049] In another embodiment of the present invention, the sensor 11 includes a temperature sensor and a water level sensor, and the display assembly 12 includes a temperature control display assembly and a water level display assembly;

[0050] First, regarding the temperature sensor and temperature control display component:

[0051] The temperature sensor is arranged below the water surface inside the water tank 1; and the main component of the temperature control display assembly 12 is the temperature control display board. There are many mature products on the market, and basically all of them can be used. Since the temperature control display assembly 12 is connected to the temperature sensor, it can display the temperature of the water in the water tank 1 in real time. An early warning module can also be installed and a warning temperature value can be set. When the water temperature drops to about 0°C, the early warning module sends a warning signal. After receiving the early warning signal, the driver or staff reviews the water temperature. After confirming that the water temperature is too low, the engine is started. If this step is not performed while the car is moving, the solenoid valve 10 and the water pump 4 are turned on. After the water temperature reaches a certain value, the engine can be turned off or the solenoid valve 10 and the water pump 4 can be directly turned off to reduce energy consumption.

[0052] Second, regarding the water level sensor and water level display components:

[0053] The water level sensor is arranged inside the water tank 1; there are many types of water level sensors, which can be roughly divided into two categories: contact water level gauges and non-contact water level gauges; among the contact water level gauges, a float-type water level gauge can be used, but considering that water may freeze, it may cause damage to the water level gauge or affect its measurement accuracy. Alternatively, a reflective water level gauge among the non-contact water level gauges can be used, which uses ultrasonic waves to monitor the water level in real time and transmit the water level data to the water level display component, so as to judge the water level in the water tank 1, and further judge whether water needs to be added or when to stop adding water.

[0054] The present invention also provides an automobile drilling rig, comprising the above-mentioned water tank antifreeze system for the automobile drilling rig; wherein, the water tank 1 is arranged on the side of the chassis of the automobile drilling rig; specifically, the automobile drilling rig generally includes two parts, a car and a drilling rig, the car is provided with a truck bed, and the drilling rig is generally arranged in the truck bed. The car serves as a carrier of the drilling rig and can flexibly transport the drilling rig to a location where operation is required; wherein, since the bottom space of the car is relatively large, the water tank 1 is generally arranged on the side of the bottom of the car, which is relatively convenient for adding water or taking water from the drilling rig.

[0055] Furthermore, in one embodiment of the present invention, the working principle of the present invention is as follows:

[0056] First, prepare for the car drilling rig to start: check in sequence whether the water tank 1 is securely installed, whether the water pump 4 is operating normally, and whether the solenoid valve 10 is operating normally; after the inspection is completed, add water to the water tank 1 and pour hot water into the water tank 1 through the water inlet 7 of the water tank 1. Avoid adding a large amount of water with a high temperature, which will generate a large amount of steam and cause excessive pressure in the water tank 1, thereby creating a safety risk. At the same time, monitor the data of the display component 12. Stop filling water when the maximum water level or the target water level is reached, and cover the water inlet 7 tightly to prevent the water in the water tank 1 from overflowing;

[0057] Secondly, the water temperature monitoring work of the automobile drilling rig during the driving process: the real-time water temperature can be monitored by the display component 12, which can be monitored at regular intervals, or an additional early warning module can be installed. After the early warning module is associated with the display component 12, it will automatically alarm when the early warning value is reached, and at this time, the solenoid valve 10 and the water pump 4 are turned on. At this time, the antifreeze that has obtained the heat of the automobile drilling rig engine flows out of the engine antifreeze circulation device 6, enters a chamber of the heat exchanger 5 through the warm air inlet pipe 91, and transfers the heat to the other chamber of the heat exchanger 5 through the partition wall. The other chamber is filled with cold water in the water tank 1 brought from the first water pipe 2 by the water pump 4. After absorbing the heat, it enters the water tank 1 through the second water pipe 3, forming an internal water circulation between the water tank 1 and the heat exchanger 5. The water temperature gradually increases. When the water temperature rises to the predetermined temperature, the solenoid valve 10 and the water pump 4 can be closed, and the water tank 1 performs subsequent heat preservation.

[0058] Finally, when the automobile drilling rig arrives at the work site, the drilling rig connects the water intake pipe to the water intake 8 of the water tank 1 to take water and drill holes. If the water temperature drops to the warning temperature value during the drilling operation, the above operation is repeated to maintain the water temperature and keep the water flowing.

[0059] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units. That is, they may be located in one place or distributed across multiple network units. Some or all of the modules may be selected based on actual needs to achieve the objectives of the present embodiment. Persons of ordinary skill in the art will be able to understand and implement the present invention without inventive effort.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
