Description

Technical Field

[0001] The utility model relates to the field of cavern anchor cable drilling auxiliary construction devices, in particular to a dust reduction device for anchor cable drilling construction in a narrow space. Background Art

[0002] During the support process of underground powerhouses, cross-anchor cable construction is involved. In order to ensure the progress of powerhouse construction, the cross-anchor cable hole drilling construction site is often located in drainage corridors, anchor holes and other caverns with small cross-sectional dimensions. Anchor drilling rigs are used in such caverns to perform anchor cable cross-drilling. The dust generated during the drilling process is extremely difficult to be effectively discharged in the limited and narrow space. Construction workers will inhale dust when working in this environment for a long time, which is harmful to their health.

[0003] Traditional dust suppression methods use exhaust fans to blow out dust or municipal sprinkler trucks to spray water. However, exhaust fans are ineffective in reducing dust, and the dust is usually discharged toward the cavern entrance and exit, causing greater dust pollution. Common municipal sprinkler trucks are generally large in size and unsuitable for confined caverns. They also tend to focus on cleaning the ground, making them less effective at clearing raised dust. Sprinkler trucks equipped with high-pressure water cannons consume a lot of water and are also unsuitable for dust suppression operations in confined caverns.

[0004] Therefore, a dust reduction device for anchor cable drilling construction in a narrow space is proposed to solve the above technical problems. Utility Model Content

[0005] The technical problem solved by the utility model is that the existing dust reduction operation in a narrow cave is not suitable for the dust removal method of an exhaust fan, and the existing municipal sprinkler has poor dust reduction effect and high water consumption.

[0007] It also includes a submersible pump disposed at the bottom of the water storage chamber, wherein the water inlet of the submersible pump is located at the bottom of the water storage chamber, and the water outlet is connected to a guide pipe, and the guide pipe passes through the partition plate and extends into the air outlet pipe interface;

[0008] It also includes a water level detection component arranged in the water storage cavity.

[0009] In particular, the water level detection component includes a hollow square tube with an open top placed vertically in the water storage chamber. A connecting port connected to the water storage chamber is opened on the bottom side wall of the square tube. A water level sensor is provided inside the square tube, and the water level sensor is electrically connected to the display screen on the outer wall of the atomizer tank.

[0010] Particularly, a one-way valve leading to the air outlet pipe interface is provided at the end of the guide pipe.

[0011] In particular, it also includes a pressure gauge communicated with the upper air cavity.

[0012] Particularly, the base comprises a horizontal plate, and the atomizing tank is mounted on the horizontal plate via connecting bolts; a plurality of universal wheels are provided at the bottom of the horizontal plate.

[0013] Furthermore, it also includes rubber anti-slip seats placed at the front and rear ends of each universal wheel, and the rubber anti-slip seats are provided with arc grooves that fit the contour of the universal wheel.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects: the utility model device uses the atomizing tank as a carrier, utilizes the air supply pipe to pass high-pressure air into the atomizing tank, and utilizes the submersible pump to guide the water in the water storage chamber into the air outlet pipe, which can effectively ensure the atomization effect and thus ensure the overall dust removal effect.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0019] like Figure 1~Figure 2As shown, a dust suppression device for anchor cable drilling construction in a narrow space includes an atomizing tank 1, which is fixed to a base 2 at the bottom; an air supply pipe interface 31 is provided at one end of the top of the atomizing tank 1, and high-pressure air is introduced into the atomizing tank 1 through the air supply pipe 3; an air outlet pipe interface 41 is provided at the other end of the top of the atomizing tank 1, and the air flow is guided to the bottom of the anchor drilling rig 5 through the air outlet pipe 4 and sprayed in the working direction of the anchor drilling rig 5; the device also includes a partition plate 6 that divides the atomizing tank 1 into an upper air chamber 61 and a lower water storage chamber 62, and also includes a water inlet pipe and an exhaust pipe that vertically penetrate the top wall of the atomizing tank 1 and the partition plate 6, and an exhaust valve is provided at the top of the exhaust pipe;

[0020] The submersible pump 7 is also provided at the bottom of the water storage chamber 62. The water inlet of the submersible pump 7 is located at the bottom of the water storage chamber 62, and the water outlet is connected to the guide pipe 8. The guide pipe 8 passes through the partition plate 6 and extends into the air outlet pipe interface 41.

[0021] It also includes a water level detection component disposed in the water storage chamber 62 .

[0022] During the actual use of the present invention, the anchor drilling rig is first positioned according to the measured hole position. The exhaust valve on the exhaust pipe on the top wall of the atomizer tank 1 is then opened, and water is poured into the atomizer tank 1 until the entire water storage chamber 62 is filled. The air supply pipe 3 is then connected to the air supply pipe interface 31, and one end of the air outlet pipe 4 is connected to the air outlet pipe interface 41. The other end of the air outlet pipe 4 is connected to the preset through-hole on the anchor drilling rig base and fixed. The end of the air outlet pipe 4 is adjusted to face the drilling direction of the anchor drilling rig. When the anchor drilling rig is started for drilling, the submersible pump 7 and the external fan are simultaneously started. The submersible pump 7 guides the water in the water storage chamber 62 through the guide pipe 8 to the air outlet pipe interface 41. The water is atomized into tiny water particles under the action of the 1.8MPa high-pressure air from the external fan, and the atomized water droplets and high-pressure air are discharged into the drilling rig working area, thereby achieving the purpose of dust reduction. During operation, in order to ensure the normal operation of the submersible pump 7, it is necessary to ensure that the exhaust valve on the exhaust pipe is in the open state. At the same time, in order to prevent external dust from falling into the water storage chamber 62, a dust cover can be provided on the top of the exhaust pipe.

[0023] As a preferred embodiment, the water level detection component includes a square tube 9 with an open top and a hollow portion vertically placed in the water storage chamber 62. A connecting port 10 connected to the water storage chamber 62 is opened on the bottom side wall of the square tube 9. A water level sensor 11 is provided inside the square tube 9. The water level sensor 11 is electrically connected to the display screen on the outer wall of the atomizer tank 1.

[0024] In this embodiment, a specific structure for water level detection is provided, wherein the square tube 9 serves as the installation position of the water level sensor 11, and is vertically fixed in the water storage chamber 62 as a whole. The top opening of the square tube 9 is located above the liquid level throughout. At the same time, the connecting port 10 on the bottom side wall of the square tube 9 connects the water storage chamber 62 and the internal space of the square tube 9, thereby ensuring that the liquid level in the water storage chamber 62 is consistent with that in the square tube 9, and the liquid level is monitored in real time through an external display screen, thereby ensuring that the water in the atomizer tank 1 can be replenished in time to avoid idling of the submersible pump 7.

[0025] As a preferred embodiment, a one-way valve 12 leading to the air outlet pipe interface 41 is provided at the end of the guide pipe 8.

[0026] In this embodiment, since the wind pressure in the air supply pipe 3 is relatively high, in order to prevent the high-pressure wind from pushing the water pumped out by the submersible pump 7 back, a one-way valve 12 is provided at the end of the guide pipe 8 to ensure that the water can only flow from the submersible pump 7 to the direction of the air supply pipe interface 31.

[0027] As a preferred embodiment, it also includes a pressure gauge 13 connected to the upper air cavity 61.

[0028] In this embodiment, the internal pressure of the air cavity 61 can be determined by the pressure gauge 13, and the output power of the external fan can be adjusted according to the actual pressure to avoid the influence of excessive or insufficient wind pressure on the dust reduction effect.

[0029] As a preferred embodiment, the base 2 includes a horizontal plate, and the atomizer 1 is mounted on the horizontal plate by connecting bolts; a plurality of universal wheels 14 are provided at the bottom of the horizontal plate.

[0030] In this embodiment, the atomizing tank 1 is fixed on a horizontal plate, and the horizontal plate is moved in time through the universal wheel 14 at the bottom, so that the atomizing tank 1 can be moved synchronously according to the drilling position of the anchor drilling rig 5, effectively increasing the versatility of the device of the utility model.

[0031] As a further embodiment, it further includes rubber anti-slip seats 15 placed at the front and rear ends of each universal wheel 14 , and the rubber anti-slip seats 15 are provided with arc grooves that match the contour of the universal wheel 14 .

[0032] Since the device of the present invention itself will generate vibrations due to reasons such as the submersible pump 7 during operation, in order to avoid the movement of the base 2 caused by the vibration, rubber anti-slip seats 15 can be set at the front and rear ends of the universal wheel 14 after determining the operation point, and the arc groove of the rubber anti-slip seat 15 can be used to clamp the position of the universal wheel 14, thereby preventing the base 2 from moving.

[0033] The words "connection" and "fixation" appearing in the description of the present invention may refer to fixed connection, processing and forming, welding, or mechanical connection. The specific meanings of the above terms in the present invention shall be understood according to the specific circumstances.

[0034] In the description of the present invention, the terms "center", "upper", "lower", "horizontal", "inner", "outer", etc., which indicate the orientation or position relationship, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0035] 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.
