Description

Technical Field

[0001] The utility model relates to the technical field of suction devices, in particular to a drilling circulating fluid suction device used for field operations in harsh environments and scarce conditions. Background Art

[0002] Drilling is widely used in geological surveys and foundation treatments to determine geological conditions and improve the overall stability and bearing capacity of foundation soil. During critical processes like concrete pouring, liquid trapped within the borehole can interfere with the uniform distribution and density of the concrete. Therefore, to ensure concrete quality, circulating fluid extraction equipment is often required to completely remove the liquid from the borehole.

[0003] However, in extreme cold, high temperatures, and other challenging conditions, such as Antarctica, traditional circulating fluid extraction equipment cannot function properly due to a lack of electricity. Furthermore, the fluid in the borehole freezes rapidly in low temperatures, hindering the extraction process and potentially degrading the quality of the concrete pour. Utility Model Content

[0004] In response to the above-mentioned defects, the technical problem to be solved by the present invention is to provide a drilling circulating fluid suction device for field operations in harsh environments and scarce conditions, so as to solve the problem of reduced quality of concrete pouring during drilling construction in field operations in harsh environments and scarce conditions in the existing technology.

[0005] To this end, the present application provides a drilling circulating fluid suction device for field operations in harsh environments and scarce conditions, comprising:

[0006] The front stage liquid storage tank is provided with a detachable liquid suction tube;

[0007] The rear stage liquid storage tank is provided with an air intake pipe connected to the air inlet of the drilling rig engine; the rear stage liquid storage tank is connected to the upper part of the front stage liquid storage tank through an air intake pipe.

[0008] Based on the above technical solution, this application utilizes the engine's intake air to generate suction power, is independent of electricity, and is suitable for field construction and easy to use. In addition, by using a cascade arrangement of the front-stage and rear-stage liquid storage tanks, the flow of liquid from the front-stage liquid storage tank to the rear-stage liquid storage tank can be observed through the suction liquid pipe, thereby determining whether the liquid in the drill hole has been completely drained, which is safe and reliable.

[0009] In the above technical solution, preferably, a first drain port is provided at the bottom of the front-stage liquid storage tank, and a second drain port is provided at the bottom of the rear-stage liquid storage tank. This allows both the front-stage and rear-stage liquid storage tanks to be drained after operation, preventing internal water from freezing and cracking. The two drain ports increase drainage options and efficiency.

[0010] In the above technical solution, preferably, a liquid level observation window is provided on the side wall of the post-stage liquid storage tank to facilitate opening the second liquid discharge port according to actual conditions.

[0011] In the above technical solution, preferably, the air suction and liquid flow pipe is made of hard transparent pipe. The air suction and liquid flow pipe can be used to observe the flow of liquid from the front stage liquid storage tank to the rear stage liquid storage tank, thereby judging whether the liquid in the drill hole is completely drained, which is convenient to use.

[0012] In the above technical solution, preferably, the liquid suction tube adopts a high-pressure wire ring hose.

[0013] In the above technical solution, preferably, the air suction liquid pipe, the liquid suction pipe and the air suction pipe are respectively connected to the front-stage liquid storage tank and the rear-stage liquid storage tank using screw fasteners.

[0014] As can be seen from the above technical solution, the present invention provides a drilling circulating fluid suction device for field operations in harsh environments and limited conditions, which solves the problem of reduced concrete pouring quality during drilling construction in field operations in harsh environments and limited conditions in the prior art. Compared with the prior art, the present invention has the following beneficial effects:

[0015] The cascaded front and rear fluid reservoirs utilize the engine's intake air to generate suction power, independent of electricity. This makes it suitable for field operations and convenient to use. Furthermore, the flow of liquid from the front to the rear reservoir can be observed through the suction pipe, allowing you to determine whether the borehole is completely drained. This is a safe and reliable device that's easy to assemble and carry, and durable. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described below 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 shall fall within the scope of protection of the present invention.

[0022] In order to provide a clearer explanation and description of the technical solution and implementation of the present invention, several preferred specific embodiments for implementing the technical solution of the present invention are introduced below.

[0023] It should be noted that the directional words such as "inside, outside", "front, back" and "left, right" in this article are expressed based on the product usage status. Obviously, the use of the corresponding directional words does not constitute a limitation on the scope of protection of this scheme.

[0024] See Figure 1 , Figure 1 The present invention is a schematic diagram of a drilling circulating fluid suction device for field operations in harsh environments and scarce conditions.

[0025] like Figure 1 As shown, the present invention provides a drilling circulating fluid suction device for field operations in harsh environments and under scarce conditions. The device comprises a front-stage liquid storage tank 10 and a rear-stage liquid storage tank 20, which are connected by an air-to-liquid suction pipe 30. A detachable suction pipe 40 is provided on the front-stage liquid storage tank 10. The suction pipe 40 is inserted into a borehole 50 and is used to suck the liquid in the borehole 50 (indicated by the dotted line in the figure) into the front-stage liquid storage tank 10. The suction pipe 40 uses a high-pressure wire ring hose, which is suitable for high-temperature environments and has high pressure resistance and reliability.

[0026] The air intake port on the downstream liquid storage tank 20 is connected to the drill rig's engine's air intake (air filter interface) via an air intake pipe 60. During operation, the air filter is first removed, and then the air intake pipe 60 is connected to the drill rig's engine's air intake. This way, when the drill rig's engine is operating, air is drawn into the intake port, creating a negative pressure in the downstream liquid storage tank 20 and the upstream liquid storage tank 10. This negative pressure draws liquid from the borehole 50 into the upstream liquid storage tank 10. When the upstream liquid storage tank 10 is full, the liquid flows through the air intake pipe 30 into the downstream liquid storage tank 20.

[0027] The air-liquid-suction pipe 30 , the liquid-suction pipe 40 and the air-suction pipe 60 are respectively connected to the front-stage liquid storage tank 10 and the rear-stage liquid storage tank 20 by screw fasteners, so as to facilitate field assembly.

[0028] The lower portions of the front-stage liquid storage tank 10 and the rear-stage liquid storage tank 20 are provided with a first drain port 11 and a second drain port 12, respectively, for draining the liquid from the front-stage liquid storage tank 10 and the rear-stage liquid storage tank 20. The first drain port 11 and the second drain port 12 are normally closed. A liquid level observation window 22 is also provided on the side wall of the rear-stage liquid storage tank 20 for observing the liquid level in the rear-stage liquid storage tank 20. When the liquid level reaches a certain height, the second drain port 12 is opened to drain the liquid.

[0029] In this application, the two-stage fluid storage tank increases the fluid storage capacity and the safety redundancy of the drilling rig engine.

[0030] Furthermore, the suction / liquid flow pipe 30 is made of a hard, transparent tubing, allowing the flow of liquid from the front-stage liquid storage tank 10 to the rear-stage liquid storage tank 20 to be observed through the suction / liquid flow pipe 30. When no more liquid flows, the liquid in the borehole 50 can be considered completely drained. At this point, the engine can be shut down to stop the suction operation. The first and second liquid drain ports 11, 12 are then opened, respectively, to drain the liquid from the front-stage liquid storage tank 10 and the rear-stage liquid storage tank 20.

[0031] Based on the description of the above specific embodiments, the drilling circulating fluid suction device provided by the present invention for field operations in harsh environments and scarce conditions has the following advantages compared with the prior art:

[0032] First, it uses the engine's intake air to generate suction power, does not rely on electricity, is suitable for field construction, and is easy to use.

[0033] Second, this application utilizes a cascaded arrangement of front and rear liquid storage tanks. Liquid flow from the front to the rear tanks can be observed through the suction pipe, allowing for complete depletion of the borehole. This approach is simple and effective. Compared to a single liquid storage tank, this solution avoids the potential safety risks associated with excessive pressure in a single tank.

[0034] Third, a liquid level observation window is provided on the side wall of the rear-stage liquid storage tank, and the second liquid discharge port can be opened for discharge according to the liquid level of the stored liquid in the rear-stage liquid storage tank, which is safe and reliable.

[0035] Finally, it should be noted that the terms "comprise," "include," or any other variations thereof, as used herein, are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0036] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any structural changes with the same or similar technical solutions as the present invention fall within the scope of protection of the present invention.
