Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust removal equipment for caverns. Background Technology

[0002] Blasting during the excavation of underground caverns generates a large amount of smoke and dust. Ventilation and dust removal utilize fans to expel the dust from the cavern. However, due to the cavern structure and the distance of the exhaust, achieving the required environmental standards takes a considerable amount of time. Therefore, effectively and quickly removing dust after blasting at the cavern face is a problem that needs to be solved. Furthermore, the smoke and dust generated by blasting spread rapidly; therefore, how to quickly remove dust as soon as possible to prevent its escape is also a problem that needs to be addressed. Utility Model Content

[0003] This utility model proposes a cavern dust removal device that enables rapid dust removal immediately after blasting, prevents smoke and dust from escaping, and improves dust removal efficiency.

[0004] The technical solution of this utility model is implemented as follows: A cavern dust removal device includes a mobile frame and several atomizing components. The atomizing components are set on the inner wall of the cavern, and the several atomizing components are spaced apart along the depth direction of the cavern. A water supply component and a water spraying component are set on the mobile frame. The atomizing components and the water spraying components are both connected to the water supply component. The atomizing components spray water mist to form a water curtain wall, which is located in front of the mobile frame. The water outlet of the water spraying component moves up and down reciprocally. The mobile frame is equipped with a controller and a vibration sensor. The controller is connected to a remote control through a wireless receiving module. The vibration sensor is used to detect the vibration signal of the blasting. The water supply component, the water spraying component, and the vibration sensor are all connected to the controller.

[0005] Furthermore, the water supply assembly includes a water tank and a high-pressure water pump. The water tank is connected to the high-pressure water pump, and the high-pressure water pump is connected to the atomizing assembly through a water delivery pipe.

[0006] Furthermore, the water spray assembly includes a high-pressure gas cylinder and several water spray pipes. The high-pressure gas cylinder is connected to the water spray pipes via a solenoid valve. The water inlet of the water spray pipe is connected to the water tank via a water inlet hose. An electric push rod is installed on the mobile frame. By extending and retracting the electric push rod, the water outlet of the water spray pipe moves up and down reciprocally.

[0007] Furthermore, the water spray pipe is located at the upper end of the water tank, with the water inlet end of the water spray pipe hinged to the upper end of the water tank, and the lower end of the electric push rod hinged to the water tank and the upper end hinged to the water spray pipe.

[0008] Furthermore, the mobile frame includes a support frame, with walking tracks on both sides of the lower end of the support frame, and the drive motors of the walking tracks are connected to the controller.

[0009] Furthermore, cameras are installed on the mobile frame.

[0010] Furthermore, the atomizing component is an atomizing nozzle, which is located on the top of the cavern or on the side wall of the cavern.

[0011] The beneficial effects of this utility model are:

[0012] This invention utilizes a water spray assembly for atomized dust removal. The water outlet of the water spray assembly moves up and down repeatedly to expand the dust removal area and improve dust removal efficiency. Simultaneously, the atomization assembly forms a water curtain to prevent smoke and dust from escaping. The inclusion of vibration sensors facilitates the immediate detection of vibration signals from blasting. The controller then activates the water spray assembly and atomization assembly, enabling rapid dust removal immediately after blasting. The controller connects to a remote control via a wireless receiver module, facilitating remote operation of the dust removal equipment and ensuring personnel safety. Furthermore, if the vibration signal fails to activate the equipment, it can be restarted via the remote control. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1-3 As shown, a cavern dust removal device includes a mobile frame and several atomizing components 1. The atomizing components 1 are disposed on the inner wall of the cavern, and the several atomizing components 1 are spaced apart along the depth direction of the cavern. The atomizing components 1 are atomizing nozzles, which are disposed on the top of the cavern or on the side wall of the cavern.

[0022] A water supply assembly is fixed on the mobile frame, comprising a water tank 2 and a high-pressure water pump 3. The water tank 2 is connected to the high-pressure water pump 3, which is connected to an atomizing assembly 1 via a water supply pipe 4, which is a high-pressure rubber hose. Water in the water tank 2 is atomized and sprayed out through the high-pressure water pump 3, the water supply pipe 4, and the atomizing assembly 1. The atomizing assembly 1 sprays water mist to form a water curtain wall 5. If there are two atomizing assemblies 1, two water curtain walls 5 will be formed. The specific number can be set as needed. The water curtain walls 5 are located at the front of the mobile frame, that is, on the side of the mobile frame closest to the tunnel face.

[0023] The mobile frame is also equipped with a water spraying assembly, which includes a high-pressure gas cylinder 6 and several water spray pipes 7. For example, there are two water spray pipes 7. The high-pressure gas cylinder 6 is fixed on the mobile frame. The high-pressure gas cylinder 6 is connected to the water spray pipes 7 through a solenoid valve. The water spray pipes 7 are located at the upper end of the water tank 2. The water inlet of the water spray pipe 7 is connected to the water tank 2 through a water inlet hose 8. The water inlet end of the water spray pipe 7 is hinged to the upper end of the water tank 2. The lower end of the electric push rod 9 is hinged to the water tank 2, and the upper end is hinged to the water spray pipe 7. The electric push rod 9 corresponds to the water spray pipe 7 one by one. By extending and retracting the electric push rod 9, the water outlet of the water spray pipe 7 moves up and down back and forth.

[0024] like Figure 2 and 4 As shown, the mobile chassis is also equipped with a controller 10 and a vibration sensor 11. The controller 10 is a PLC controller. The controller 10 is connected to the remote controller 13 via a wireless receiving module 12. The vibration sensor 11 is used to detect the vibration signal of the blasting. Cameras 14 are installed on all sides of the mobile chassis to observe the surrounding environment.

[0025] like Figure 3 and 4As shown, the mobile frame includes a support frame 15, and walking tracks 16 are provided on both sides of the lower end of the support frame 15. The drive motor 17, solenoid valve, high-pressure water pump 3, camera 14, and vibration sensor 11 of the walking tracks 16 are all connected to the controller 10.

[0026] The method of using the dust removal equipment in the underground cavern is as follows: After the explosive charge is completed at the working face of the underground cavern, the dust removal equipment is moved to the working position by the controller 10 via the remote control 13. After the blast, the vibration sensor 11 detects the vibration signal of the blast and transmits it to the controller 10. The controller 10 opens the solenoid valve (if the start fails due to vibration signal detection, the solenoid valve can be started by the controller 10 via the remote control 13). With the solenoid valve open, the high-pressure gas in the high-pressure gas cylinder 6 is ejected. Using Bernoulli's theorem, water is drawn out of the water tank 2 through the water inlet hose 8 and sprayed out through the water spray pipe 7. The pressure of the high-pressure gas is very high, and the entire spraying time is about 50 seconds. A large amount of water will be sprayed out for water atomization. At this time, the pressure in the high-pressure gas cylinder 6 will still be more than ten megapascals. During the water spraying process, the electric push rod 9 pushes the water spray pipe 7 to move up and down according to a certain pattern to perform water atomization. The high-pressure water pump 3 is started, and the atomization component 1 works to form several water curtain walls 5. Cameras 14 are installed around the dust removal equipment to observe the surrounding situation.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
