Technical Field

[0001] This utility model relates to the field of drilling fluid technology, and in particular to an automatic measuring instrument for drilling fluid rheological parameters. Background Technology

[0002] Drilling fluid is a general term for various circulating fluids that meet the needs of drilling work through multiple functions. Drilling fluid is the lifeblood of drilling, also known as borehole flushing fluid. Drilling fluid can be classified according to its composition into water, mud, clay-free flushing fluid, emulsion, foam, and compressed air, etc. Water is the earliest drilling fluid used. It does not require treatment, is easy to use, and is suitable for areas with intact rock formations and abundant water sources.

[0003] Currently, most existing drilling fluid rheological parameter automatic measuring instruments are bulky and used in various scenarios, making them difficult to move in uneven environments, especially during field operations. This results in inconvenience and low overall flexibility. Therefore, we propose an automatic drilling fluid rheological parameter measuring instrument to solve the problems mentioned above.

[0017] In the following description of this utility model, the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device must have a specific orientation.

[0018] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Example 1, such as Figures 1 to 5As shown, the automatic drilling fluid rheological parameter measuring instrument of this utility model includes a movable base 1 and an equipment component 2. The bottom ends of the equipment component 2 are located at the top center of the movable base 1. The movable base 1 includes a long strip-shaped base shell 106. The top surface of the base shell 106 is provided with an anti-slip pad 101. The anti-slip pad 101 is provided with slots 102 near the front and rear ends. Each slot 102 is fitted with a locking block 103. The upper end of the locking block 103 is higher than the anti-slip pad 101. Each locking block 103 is provided with a locking block lug on its outer side. Each locking block lug is provided with a bolt hole 105. Bolts 104 pass through the bolt holes 105 and the through holes on the anti-slip pad 101 and are fixedly connected to the top wall of the base shell 106.

[0021] A micro servo motor 113 is fixedly installed at the center of the inner wall of the base housing 106. A ball screw 111 is fixedly connected to the output end of the micro servo motor 113. Vertically extending slide grooves 108 are respectively provided on the inner side of the front and rear side walls of the base housing 106. Slide blocks 107 that can move up and down along the slide grooves 108 are respectively embedded in the slide grooves 108. A movable plate 112 is fixedly connected between the front and rear slide blocks 107. A spring column 115 is fixedly installed at the front and rear positions of the bottom of the movable plate 112. A moving wheel 114 is fixedly installed at the lower end of the spring column 115.

[0022] The effect achieved in Example 1 is as follows: the anti-slip mat 101 and the base housing 106 are supported on the bottom of the left and right sides of the measuring instrument housing 201, and the locking blocks 103 limit the front and rear directions of the four corners of the bottom of the measuring instrument housing 201 to prevent the measuring instrument housing 201 from slipping. The equipment component 2 includes the measuring instrument housing 201, and the bottom of the left and right sides of the measuring instrument housing 201 can be fixedly connected to the anti-slip mat 101; if it is not needed to move for a long time, the two base housings 106 can be disassembled through the cooperation of the slots 102, the locking blocks 103 and the bolts 104, so that the anti-slip mat 101 can directly contact the ground, ensuring that the whole can be used stably, and also making it convenient for users to maintain or replace the components inside the base housing 106. In actual use, the tires of its moving wheels 114 are all-terrain tires, which can be easily moved on uneven ground with the cooperation of the spring column 115.

[0023] Example 2, as Figures 1 to 5As shown, the outer sides of the locking block 103 are fixed to the top of the base housing 106 by bolts 104. The upper end of the spring column 115 is fixedly connected to the bottom surface of the movable plate 112, and the other end of the spring column 115 is fixedly connected to the top surface of the moving wheel 114. The thread of the ball screw 111 engages with the screw nut, which is fixed below the through hole of the movable plate 112. An anti-slip base plate 110 is fixedly connected to the bottom of the base housing 106. A round rod 109 is fixedly connected to the front and rear positions of the inner wall of the top of the base housing 106. The middle part of the round rod 109 passes through the corresponding round hole of the movable plate 112 with clearance fit, and together they play a guiding role when the movable plate 112 floats.

[0024] The front outer surface of the measuring instrument housing 201 is hinged with a cabinet door 202. The bottom of the measuring instrument housing 201 is fixedly connected to the top of the anti-slip mat 101. A liquid inlet pipe 203 is provided through one side wall of the measuring instrument housing 201.

[0025] The effect achieved in Example 2 is as follows: When the entire assembly is stationary, the anti-slip base plate 110 is in contact with the ground. The anti-slip base plate 110 prevents displacement of the entire assembly during use. Furthermore, the round rod 109, the sliding groove 108, and the slider 107 improve the stability of the movable plate 112 during vertical movement. Figure 1 As shown, the cabinet door 202 is equipped with a control panel. In actual use, the control panel is electrically connected to the components so that the operator can control and use them.

[0026] Working Principle: When the entire unit needs to be moved, the ball screw 111 can rotate forward or backward via the micro servo motor 113. During rotation, it drives the movable plate 112 to move up and down within the base housing 106. The base housing 106 then drives the spring column 115 and the moving wheel 114 to move up and down. At this time, the slider 107 slides up and down along the groove 108, and the guide rod 109 improves the stability of the movable plate 112 during its up-and-down movement. When the spring column 115 and the moving wheel 114 move downward, they pass through the clearance grooves of the base housing 106 and the anti-slip base plate 110, making direct contact with the ground and lifting the entire unit, facilitating movement of the instrument. The elasticity of the spring column 115 provides a cushioning effect, while the all-terrain tires on the moving wheel 114 facilitate movement on uneven ground. This combination enhances the overall flexibility of the instrument. When movement is not required, the caster wheel 114 retracts into the base housing 106, allowing the anti-slip base plate 110 to contact the ground, thus ensuring the overall stability during use.
