Description

Technical Field

[0001] This utility model relates to the field of blasting, and in particular to a negative pressure ejector drainage device for water holes in blasting projects. Background Technology

[0002] In open-pit or underground blasting operations, blast holes often accumulate water due to rainwater, groundwater, and other factors, especially in vertical or inclined holes. Water accumulation in the holes leads to a series of serious problems: First, it reduces blasting effectiveness: water dilutes the explosives, affecting their detonation performance, resulting in insufficient blast energy and a high proportion of large fragments. Second, it damages the explosive structure: for rolled emulsion explosives, water immersion can cause deformation, sinking, or even misfires. Third, it poses safety hazards: water can cause explosives to malfunction, resulting in misfires and increasing handling risks and costs.

[0003] Traditional drainage methods, such as using high-pressure air blowing, scooping with buckets, or using ordinary water pumps, are inefficient, ineffective, and labor-intensive. High-pressure air blowing can easily generate water mist, which can affect operators and equipment. Moreover, when there are geological defects such as karst caves, faults, or weak interlayers in the blasting area, it is necessary to adjust the path by bending the blast holes to avoid potential hazards. For blast holes with a certain degree of curvature, traditional drainage methods are difficult to drain the water accumulated at the bottom of the curved blast holes. Utility Model Content

[0004] This utility model provides a negative pressure ejector-type drainage device for water holes in blasting projects, which solves the problems of water accumulation in blast holes being difficult to drain, reducing blasting effect, damaging explosive structure, and creating safety hazards. Traditional drainage methods are inefficient, ineffective, labor-intensive, and affect operators and equipment.

[0005] Another problem solved by this invention is that traditional drainage methods are difficult to drain water from the bottom of blast holes with a certain curvature.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a negative pressure ejector drainage device for water holes in blasting projects, including a negative pressure generator, a steering hose at the bottom of the negative pressure generator, the steering hose including four water pipes and multiple connecting discs, a rotating rod on the connecting disc, a steering motor between two adjacent rotating rods, and the water pipes passing through multiple connecting discs.

[0007] In the preferred embodiment, an air compressor is provided on one side of the negative pressure generator, and a water tank is provided on the other side of the negative pressure generator, with an air outlet on the top of the water tank.

[0008] In a preferred embodiment, the negative pressure generator includes an air inlet pipe, a converging section connected to one side of the air inlet pipe, a diffuser section connected to one side of the converging section, and an outlet at one end of the diffuser section.

[0009] In the preferred embodiment, the other side of the air intake pipe is provided with a connected air inlet, the bottom of the air intake pipe is provided with a connecting pipe port, the connecting pipe port is connected to the rotating rod, and the outlet is connected to the water tank.

[0010] In the preferred embodiment, the steering hose is provided with a corrugated pipe on the outside, the connecting plate is provided with a central hole, the connecting plate is provided with four water pipe holes and multiple mounting seats, and multiple springs are provided between two adjacent connecting plates.

[0011] In the preferred embodiment, the rotating rod passes through the central hole, the connecting plate is installed inside the bellows, and both ends of the spring are connected to the connecting plate via mounting bases.

[0012] In the preferred embodiment, the rotating rod includes a connecting shaft, with U-shaped frames at both ends of the connecting shaft and rotating seats on both sides of the U-shaped frames. The steering motor includes a dual-output shaft motor, with connecting seats on both sides of the dual-output shaft motor.

[0013] In the preferred embodiment, the rotating seat on the U-shaped frame at one end of the rotating rod is connected to the output shaft of the dual-output shaft motor, the rotating seat on the U-shaped frame at the other end of the rotating rod is connected to the connecting seat, and the connecting shaft is connected to the center hole.

[0014] In the preferred embodiment, a filter screen is provided at the bottom of the steering hose, and the filter screen is connected to the water pipe.

[0015] The beneficial effects of this invention are as follows: When drainage of the blast hole is required, and the blast hole is vertical, horizontal, or inclined, the steering motor at the top of the steering hose is rotated to adjust the angle of the entire steering hose so that the lower end of the steering hose is in a horizontal, vertical, or inclined state. The steering hose is then inserted into the blast hole, and the negative pressure generator is turned on, allowing high-pressure gas to enter. The negative pressure generator instantly generates a strong suction force in the water pipe, rapidly sucking the water accumulated at the bottom of the hole into the water tank. The drainage situation is observed, and when no more water flows out of the negative pressure suction pipe outlet, the gas source is turned off, and the steering hose is removed from the blast hole. The overall structure effectively prevents water accumulation in the blast hole from being difficult to drain, avoiding the phenomenon that water accumulation reduces the blasting effect, damages the explosive structure, and creates safety hazards. Compared with traditional drainage methods, this device is more efficient, more effective, and less labor-intensive. It avoids water spray caused by high-pressure air blowing, thus preventing the impact on operators and equipment. The overall structure is highly efficient and fast, utilizing the Venturi effect to generate a strong negative pressure, resulting in a large suction force and fast drainage speed, quickly draining the water accumulated in the hole.

[0016] When the breached area contains special features such as karst caves and faults, and the blast hole has a certain angle of curvature, multiple steering motors on the steering hose are driven to rotate the rotating rod during the process of the steering hose entering the blast hole. This causes multiple springs to deform, so that the steering hose presents a certain curvature angle. This allows the steering hose to adapt to the curvature angle of the blast hole, avoiding the phenomenon that traditional drainage methods cannot reach the bottom of the curved blast hole, resulting in water accumulating at the bottom of the blast hole and being unable to drain.

[0018] Example 1: like Figure 1-6The negative pressure ejector-type drainage device for water holes in blasting projects includes a negative pressure generator 2. The bottom of the negative pressure generator 2 is equipped with a steering hose 3, which includes four water pipes 9 and multiple connecting discs 5. A rotating rod 6 is mounted on each connecting disc 5, and a steering motor 7 is located between adjacent rotating rods 6. The water pipes 9 pass through the multiple connecting discs 5. With this structure, when drainage of the blast hole is required, and the blast hole is vertical, horizontal, or inclined, the steering motor 7 at the top of the steering hose 3 is rotated to adjust the angle of the entire steering hose 3, so that the lower end of the steering hose 3 is in a horizontal, vertical, or inclined state. The steering hose 3 is then inserted into the blast hole, and the negative pressure generator 2 is turned on, allowing high-pressure gas to enter. The negative pressure generator 2 instantly generates a strong suction force within the water pipes 9, rapidly drawing water accumulated at the bottom of the hole into a water tank 11. The drainage situation is observed, and when no more water flows out of the negative pressure suction pipe outlet, the gas source is turned off, and the steering hose 3 is removed from the blast hole. The overall structure effectively prevents water from accumulating in the borehole, thus avoiding reduced blasting effectiveness, damage to the explosive structure, and potential safety hazards. Compared to traditional drainage methods, this device is more efficient, effective, and less labor-intensive. It avoids water spray caused by high-pressure airflow, preventing any impact on operators and equipment. The overall structure is highly efficient and fast, utilizing the Venturi effect to generate strong negative pressure, resulting in high suction force and rapid drainage, quickly drying out the water in the borehole.

[0019] When the breached area contains special features such as karst caves and faults, and the blast hole has a certain angle of curvature, as the steering hose 3 is inserted into the blast hole, multiple steering motors 7 on the steering hose 3 are driven to rotate the rotating rod 6, thereby deforming multiple springs 8 and causing the steering hose 3 to present a certain curvature angle. This allows the steering hose 3 to adapt to the curvature angle of the blast hole, avoiding the phenomenon that traditional drainage methods cannot reach the bottom of the curved blast hole, resulting in water accumulation at the bottom of the blast hole that cannot be drained.

[0020] In the preferred embodiment, an air compressor 1 is located on one side of the negative pressure generator 2, and a water tank 11 is located on the other side. The top of the water tank 11 has an air outlet 1101. With this structure, the steering hose 3 is inserted into the borehole, and the negative pressure generator 2 is turned on, allowing high-pressure gas to enter. The negative pressure generator 2 instantly generates a strong suction force within the water pipe 9, rapidly drawing water accumulated at the bottom of the borehole into the water tank 11. The drainage is observed; when no more water flows out of the negative pressure suction pipe outlet, the air source is turned off, and the steering hose 3 is removed from the borehole. The air outlet 1101 at the top of the water tank 11 allows the high-pressure air to be discharged.

[0021] In a preferred embodiment, the negative pressure generator 2 includes an inlet pipe 201, a converging section 202 connected to one side of the inlet pipe 201, a diffuser section 203 connected to one side of the converging section 202, and an outlet 204 at one end of the diffuser section 203. With this structure, the negative pressure generator 2 is connected to an existing air compressor 1 on-site via a high-pressure inlet port. When high-pressure gas flows through the narrow throat of the venturi tube, a strong negative pressure is generated at the throat according to Bernoulli's principle.

[0022] In the preferred embodiment, the other side of the air intake pipe 201 is provided with a connected air inlet 206, the bottom of the air intake pipe 201 is provided with a connecting pipe port 205, the connecting pipe port 205 is connected to the rotating rod 6, and the outlet 204 is connected to the water tank 11.

[0023] In the preferred embodiment, the steering hose 3 is externally provided with a corrugated pipe 4, the connecting plate 5 has a central hole 501, four water pipe holes 502 and multiple mounting seats 503, and multiple springs 8 are provided between two adjacent connecting plates 5. With this structure, when the breached area contains special features such as karst caves or faults, and the blast hole has a certain angle of curvature, as the steering hose 3 penetrates the blast hole, multiple steering motors 7 on the steering hose 3 are driven to rotate the rotating rod 6, causing the multiple springs 8 to deform and thus adjust the steering hose 3 to a certain curvature angle. This allows the steering hose 3 to adapt to the curvature angle of the blast hole, avoiding the problem of traditional drainage methods failing to reach the bottom of the curved blast hole, resulting in water accumulation at the bottom of the blast hole.

[0024] In the preferred embodiment, the rotating rod 6 passes through the central hole 501, the connecting plate 5 is installed inside the bellows 4, and both ends of the spring 8 are connected to the connecting plate 5 via mounting seats 503. With this structure, the connecting shaft 601 of the rotating rod 6 passes through the central hole 501, and the connecting shaft 601 of the rotating rod 6 is connected to the connecting plate 5 through the central hole 501.

[0025] In a preferred embodiment, the rotating rod 6 includes a connecting shaft 601, with U-shaped brackets 602 at both ends of the connecting shaft 601. Rotating seats 603 are provided on both sides of the U-shaped brackets 602. The steering motor 7 includes a dual-output shaft motor 701, with connecting seats 702 on both sides of the dual-output shaft motor 701. With this structure, the rotating rod 6 is connected to the steering motor 7 via the U-shaped brackets 602. The steering motor 7 has output shafts on both sides and connecting seats 702 on the other two sides. Two adjacent rotating rods 6 are connected by rotating 90° via the steering motor 7.

[0026] In the preferred embodiment, the rotating seat 603 on the U-shaped frame 602 at one end of the rotating rod 6 is connected to the output shaft of the dual-output shaft motor 701, and the rotating seat 603 on the U-shaped frame 602 at the other end of the rotating rod 6 is connected to the connecting seat 702. The connecting shaft 601 is connected to the center hole 501. This structure drives the dual-output shaft motor 701, causing its two output shafts to rotate, which in turn causes adjacent rotating rods 6 to rotate relative to each other. This compresses one spring 8 and stretches the other spring 8, causing the bellows 4 and water pipe 9 to bend, and ultimately bending the entire steering hose 3 structure to adapt to the curved borehole. Multiple dual-output shaft motors 701 are connected to the controller via their respective wires.

[0027] Water pipe 9 is made of silicone. Silicone water pipe 9 has high flexibility and an elongation rate of 300%-500%. It can quickly return to its original shape after being pressed or bent. It still maintains good elasticity in low temperature environments and has no risk of stiffness and breakage.

[0028] In a preferred embodiment, a filter screen 10 is provided at the bottom of the steering hose 3, and the filter screen 10 is connected to the water pipe 9. With this structure, a camera is provided at the top of the filter screen 10, and multiple cameras are also provided on the corrugated pipe 4 outside the steering hose 3 located on the connecting plate 5, to facilitate penetration of the steering hose 3 into the borehole. The filter screen 10 filters out fine gravel and impurities inside the borehole.

[0029] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
