DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, purposes and effects achieved by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0026] The directionality or its approximate phrases described in the whole text of the utility model, for example, "front", "back", "left", "right", "up", "down", "inner", "outer", "side" and the like, are mainly reference to the direction of the drawings, and each directionality or its approximate phrase is only used to assist in description and understanding of the embodiments of the utility model, and is not used to limit the utility model.

[0027] For example, Figure 1 And Figure 2As shown, the oilfield heating equipment, including water tank 1, water tank 1 left end and right end lower part together fixedly connected with connecting pipe 2, water tank 1 front end right part fixedly connected with automatic water injection device 6, water tank 1 lower end fixedly connected with lifting platform device 3, lifting platform device 3 lower part four corners are fixedly connected with self-locking universal wheel 4, water tank 1 upper end right part rear side fixedly connected with air outlet 7, water tank 1 upper end and rear end left part together fixedly connected with circulating heating device 5, water tank 1 right wall upper part fixedly connected with water level monitor 8.

[0028] The device can heat the crude oil being transported through water bath, thereby reducing the viscosity of the crude oil and improving the flowability of the crude oil.

[0029] The device can be powered by an external power supply.

[0030] Before the device is implemented, the oil inlet and outlet of the connecting pipe 2 are connected with the crude oil conveying pipe, so that the crude oil passes through the connecting pipe 2 during transportation, and clean water is injected in advance in the water tank 1 and the automatic water injection device 6.

[0031] In the above, before the device is implemented, the device is moved to the position of the crude oil conveying pipe through the self-locking universal wheel 4, then the lifting platform device 3 is shaken to move the water tank 1 upward, and then the connecting pipe 2 is connected with the crude oil conveying pipe. After the connection is completed, the circulating heating device 5 is started to work, so that the circulating heating device 5 heats the water in the water tank 1, and the crude oil passing through the connecting pipe 2 is heated. When the water is heated, steam is generated, which flows upward and floats out of the outside through the air outlet 7. The generation of steam reduces the amount of clean water in the water tank 1. When the water level reaches the limit of the water level monitor 8, information is transmitted to the automatic water injection device 6. After receiving the information, the automatic water injection device 6 injects water into the water tank 1. When the water level in the water tank 1 exceeds the water level monitor 8, the water level monitor 8 transmits information to the automatic water injection device 6 again, so that the automatic water injection device 6 stops injecting water, and the water in the water tank 1 is always kept in a balanced state.

[0032] In the above, the circulating heating device 5 can circulate the clean water in the water tank 1, so that the clean water in the water tank 1 can always be kept at a high temperature.

[0033] In the above, through the design of the multiple U-shaped pipes of the connecting pipe 2, the crude oil has sufficient contact time with hot water when passing through the connecting pipe 2, so that the crude oil can be heated to 70-75 DEG C, thereby reducing the viscosity of the crude oil and improving the flowability of the crude oil.

[0034] In the above, the water level monitor 8 is a device for measuring the liquid level, based on the principle of liquid pressure transmission and open liquid level measurement.

[0035] The automatic water injection device 6 is composed of a water storage tank, a water injection pump and a water pipe. The water storage tank is fixedly connected to the right part of the front end of the water tank 1. The water injection pump is fixedly connected to the upper end of the water storage tank. The water pipe is fixedly connected between the lower end of the water storage tank and the water injection pump. When the water level monitor 8 transmits information to the water injection pump, the water injection pump injects clean water in the water storage tank into the water tank 1 through the water pipe, so that the clean water in the water tank 1 is kept full.

[0036] Further, in order to achieve the purpose of the circulating heating device 5 for circulating heating the clean water in the water tank 1, referring to Figure 3 , the circulating heating device 5 comprises a water pump 51 fixedly connected to the left part of the upper end of the water tank 1. The input end of the water pump 51 is fixedly connected with a water conveying pipe one 52. The water inlet of the water conveying pipe one 52 is fixedly connected with a heating tank 53. The output end of the heating tank 53 is fixedly connected with a water conveying pipe two 54. The output end of the water pump 51 and the water conveying pipe two 54 are communicated with the water tank 1. The heating tank 53 is fixedly connected to the left part of the rear end of the water tank 1.

[0037] In the above, the water pump 51 is started to move, so that the water pump 51 draws the clean water in the water tank 1 into the water conveying pipe two 54, and then injects the clean water from the water conveying pipe two 54 into the heating tank 53, so that the heating tank 53 heats the clean water, and then injects the heated clean water into the water conveying pipe one 52. The water conveying pipe one 52 transmits the clean water to the water pump 51. Finally, the water pump 51 injects the clean water into the water tank 1. The above process is repeated to achieve the purpose of circulating heating the clean water in the water tank 1.

[0038] In the above, the heating tank 53 is a device that can accurately control temperature and provide a stable heating environment for internal items. Its working principle usually involves built-in heating elements and a temperature control system. The heating element is responsible for generating heat, while the temperature control system monitors and adjusts the temperature inside the tank to ensure it remains within the set range.

[0039] Further, in order to achieve the purpose of the lifting platform device 3 for adjusting the height of the water tank 1, referring to Figure 4 and Figure 5 , the lifting platform device 3 comprises a convex plate 33 and a support plate 31. The convex plate 33 is fixedly connected to the lower end of the water tank 1. The lower end of the convex plate 33 is fixedly connected with a lifting mechanism 32. The support plate 31 is located below the convex plate 33. The upper end of the support plate 31 is fixedly connected with four slide shells 35. The inner cavities of the four slide shells 35 are slidably connected with four slide columns 34. The lower part of the lifting mechanism 32 slides in the inner cavity of the support plate 31. The upper ends of the four slide columns 34 are fixedly connected with the lower end of the convex plate 33.

[0040] The lifting mechanism 32 comprises two threaded blocks 321 which are respectively slid in the left and right parts of the inner cavity of the supporting plate 31, the inner cavities of the two threaded blocks 321 are threadedly connected with a bidirectional threaded rod 325, the outer surface of the middle part of the bidirectional threaded rod 325 is fixedly connected with a limiting block 323, the upper ends of the two threaded blocks 321 and the left and right sides of the middle part of the lower end of the convex plate 33 are fixedly connected with arc-shaped blocks 324, the two arc-shaped blocks 324 on the same side are rotatably connected with a connecting rod 322, and the left end of the bidirectional threaded rod 325 is fixedly connected with a rocker 326; the bidirectional threaded rod 325 is rotatably connected with the left and right walls of the inner cavity of the supporting plate 31.

[0041] In the above, the rocker 326 is rotated, and the bidirectional threaded rod 325 is rotated together with the rocker 326, the bidirectional threaded rod 325 drives the two threaded blocks 321 to move towards each other through the threaded connection relationship, the connecting rod 322 is in a vertical state through the rotating connection relationship between the arc-shaped block 324 and the connecting rod 322 when the threaded block 321 moves, and then the two arc-shaped blocks 324 on the upper part lift the convex plate 33 to move upwards, and then the water tank 1 is pushed to move upwards.

[0042] In the above, when the convex plate 33 moves upwards, the sliding column 34 slides in the inner cavity of the sliding shell 35, and the sliding column 34 supports the convex plate 33.

[0043] It should be particularly pointed out that the specific installation mode of the water pump 51, the heating box 53 and the water level monitor 8, the connection mode of the circuit and the control method all belong to the conventional design, and the utility model will not be described in detail.

[0044] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the utility model, and various changes and improvements can be made without departing from the spirit and scope of the utility model, and these changes and improvements all fall within the scope of the utility model claimed. The scope of protection of the utility model is defined by the appended claims and their equivalents.
