Description

Technical Field

[0001] The utility model relates to the technical field of mine blasting, in particular to a beacon positioning device for tracking the movement path of ore and rock in geotechnical blasting. Background Art

[0002] In mine blasting engineering, under the action of explosion energy, the rock and ore body will deform, break, loosen, be thrown and accumulated, and the throwing and accumulation of rock blocks will cause the redistribution of ore. Due to the redistribution of ore after explosion, combined with unreasonable loading plans and other problems, ore loss and dilution occur.

[0003] In order to solve the above problems, Chinese Patent (Publication No.: CN109688552A) provides an open-pit mine blasting ore flow tracking system and method. In this solution, tracking balls are set in the area where the ore is to be blasted, and after the ore blasting is completed, the communication detector is used to locate the tracking balls in the blasted ore pile. Since the displacement amount of the ore during blasting can be monitored, the trajectory of the ore displacement in the blasting interval can be simulated, so as to determine the position of the ore / waste rock boundary. Through the ore-rock boundary curve fitting algorithm based on the displacement distribution of the intelligent tracking ball during blasting, the ore boundaries of different grades can be automatically delineated according to the positioning results, reducing the mining dilution rate and ore loss rate caused by blasting.

[0004] Although this solution can monitor the position of the ore to determine the position of the ore / waste rock boundary, the recovery of the tracking balls in this solution is inconvenient. When recovering the tracking balls, after the ore blasting is completed, the communication detector is used to locate the tracking balls in the blasted ore pile. Since most of the tracking balls will be buried in the rock, it is difficult for the detector to accurately display the position of the tracking balls, and it is necessary to search for the tracking balls in a large range, which is inconvenient to use, and the tracking balls are easy to lose, resulting in a high use cost. Summary of the Utility Model

[0005] Aiming at the above defects, the technical problem to be solved by the utility model is to provide a beacon positioning device for tracking the movement path of ore and rock in geotechnical blasting. This beacon positioning device is easy to find and not easy to lose, reducing the difficulty of finding the beacon positioning device.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A beacon positioning device for tracking the movement path of ore and rock in geotechnical blasting includes a housing. A trajectory sensing module, a wireless communication module, a power supply module, a processor and a smoke generator are arranged in the housing. The trajectory sensing module, the wireless communication module and the smoke generator are all electrically connected to the processor. The trajectory sensing module is used to obtain the movement trajectory of the housing. The power supply module is used to supply power to the trajectory sensing module, the wireless communication module, the processor and the smoke generator. A plurality of smoke outlets are opened on the housing.

[0008] By adopting the above solution, before blasting, the beacon positioning device is buried in the blasting area. During the blasting process, under the action of the explosion energy, the rock and ore body deforms, breaks, loosens, is thrown and accumulated, and the beacon positioning device is redistributed together with the ore. By tracking the movement trajectory of the beacon positioning device through the trajectory sensing module, the distribution of the ore after blasting can be determined. Since a smoke generator is provided inside the housing, when recovering the beacon positioning device, a signal to start the smoke generator is sent to the wireless communication module through a remote control or other wireless communication device. After receiving the signal, the processor controls the smoke generator to start. After the smoke generator starts, it generates smoke, and the smoke is discharged outside the housing through the smoke outlet holes. The smoke seeps out to the ground surface through the gaps between the rock and soil. After the smoke appears on the ground surface, the staff can quickly find the position of the beacon positioning device, which is convenient for recovery. And because the smoke is relatively obvious, the loss probability of the beacon positioning device is reduced, and the use cost is saved.

[0009] The present utility model is further configured such that the smoke outlet of the smoke generator is in one-to-one correspondence and communication with the smoke outlet holes through a plurality of smoke pipes. The smoke at the smoke outlet of the smoke generator is directly guided to the smoke outlet holes through the smoke pipes, which enables the smoke to be discharged outside the housing more quickly, thereby accelerating the speed of the smoke seeping out to the ground surface and enabling the staff to discover the beacon positioning device faster.

[0010] The present utility model is further configured such that a filter screen is provided in the smoke outlet holes. The filter screen can prevent dust from entering the smoke pipes and the interior of the housing.

[0011] The present utility model is further configured such that the housing is filled with a buffer material. The buffer material can protect the electronic components inside the housing and reduce the impact generated by the explosion on the electronic components.

[0012] The present utility model is further configured such that the buffer material is made of foam plastic. Foam plastic has characteristics such as light weight, heat insulation, sound absorption, and shock absorption, and can play a good role in protecting the electronic components inside the housing.

[0013] The present utility model is further configured such that the trajectory sensing module includes an inclination angle sensor, a direction sensor, and an acceleration sensor, and the inclination angle sensor, the direction sensor, and the acceleration sensor are all electrically connected to the processor. The movement path of the beacon positioning device during the movement along with the ore and rock is accurately monitored through the inclination angle sensor, the direction sensor, and the acceleration sensor.

[0014] The present utility model is further configured such that there are gaps between the tilt angle sensor, the azimuth sensor, and the acceleration sensor. Since the explosion has a large impact force on the housing, local deformation of the housing will occur, which may easily cause mutual extrusion between two adjacent sensors, leading to damage to the adjacent sensors. Since there are gaps between the tilt angle sensor, the azimuth sensor, and the acceleration sensor, it is difficult for adjacent sensors to be mutually extruded, thus reducing the risk of sensor damage.

[0015] The present utility model is further configured such that the housing is a hollow polyhedron. Since the polyhedron surface has edges and corners, it makes the beacon positioning device not easily continue to roll after landing, so that the distribution of ore and rock can be more accurately determined through the distribution of the beacon positioning device.

[0016] The present utility model is further configured such that the housing is a hollow cube.

[0017] The present utility model is further configured to further include a storage module. The storage module is arranged inside the housing. The storage module is electrically connected to the processor, and the power supply module is also used to supply power to the storage module. Through the storage module, the motion data of the beacon positioning device can be stored in the storage module.

[0018] In summary, the beacon positioning device provided by the present utility model for tracking the movement path of ore and rock in geotechnical blasting has at least the following beneficial effects:

[0019] 1. Through the smoke, the staff can quickly find the position of the beacon positioning device, which is convenient for recovery.

[0020] 2. Since the smoke is relatively obvious, the loss probability of the beacon positioning device is reduced, saving the usage cost. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the appended Figure 1-2 drawings and specific implementation manners.

[0026] Please refer to Figure 1-2 , the beacon positioning device for tracking the movement path of ore and rock in geotechnical blasting provided in this embodiment includes a housing 1, and a trajectory sensing module 2, a wireless communication module 3, a power supply module 4, a processor 5, and a smoke generator 6 are arranged in the housing 1. The trajectory sensing module 2, the wireless communication module 3, and the smoke generator 6 are all electrically connected to the processor 5. The power supply module 4 is used to supply power to the trajectory sensing module 2, the wireless communication module 3, the processor 5, and the smoke generator 6. A plurality of smoke outlets 7 are opened on the housing 1. Among them, the trajectory sensing module 2 is used to obtain the movement trajectory of the housing 1, the wireless communication module 3 is used for wireless communication, and the processor 5 is a central processing unit in the prior art. The smoke generator 6 is used to generate smoke, and the smoke generated by the smoke generator 6 is preferably smoke with eye-catching colors such as red and yellow. The housing 1 is preferably made of ABS plastic, which can withstand strong impact forces in the blasting environment and has the characteristics of high temperature resistance, waterproofness, and wear resistance. The housing 1 is preferably a hollow polyhedron, and more preferably, the housing 1 is a hollow cube. More preferably, one smoke outlet 7 is opened on each of the six faces of the cube-shaped housing 1. Among them, the control program used in the processor 5 is a conventional program in the prior art.

[0027] By adopting the above solution, before blasting, the beacon positioning device is buried in the blasting area. During the blasting process, under the action of the explosion energy, the rock and ore body deforms, breaks, loosens, is thrown and accumulated, and the beacon positioning device is redistributed together with the ore. The trajectory sensing module 2 tracks the movement trajectory of the beacon positioning device to determine the distribution of the ore after blasting. The movement trajectory data obtained by the trajectory sensing module 2 is wirelessly transmitted to an external wireless receiving device through the wireless communication module 3, and the computer can perform distribution analysis of the ore body after blasting based on the movement trajectory data. Since the smoke generator 6 is provided in the housing 1, when recovering the beacon positioning device, a signal to start the smoke generator 6 is sent to the wireless communication module 3 through a remote control or other wireless communication device. The wireless communication module 3 transmits the signal to the processor 5, and after receiving the signal to start the smoke generator 6, the processor 5 controls the smoke generator 6 to start. After the smoke generator 6 starts, it generates smoke, and the smoke is discharged outside the housing 1 through the smoke outlet hole 7, and the smoke seeps out to the ground surface through the gaps between the rock and soil. After the smoke appears on the ground surface, the staff can quickly find the position of the beacon positioning device, which is convenient for recovery. And because the smoke is relatively obvious, the position of the beacon positioning device can be accurately found, reducing the loss probability of the beacon positioning device and saving the use cost. A remote control dedicated to starting and closing the smoke generator 6 can be used in cooperation. The remote control can send signals to start and close the smoke generator 6 to the wireless communication module 3. The processor 5 controls the smoke generator 6 to start according to the start signal of the smoke generator 6 received by the wireless communication module 3, and the processor 5 controls the smoke generator 6 to close according to the close signal of the smoke generator 6 received by the wireless communication module 3.

[0028] Among them, the smoke generator 6 is a prior art. The specific structure of the smoke generator 6 in the prior art includes a smoke chamber, smoke oil and a heating wire. The smoke oil is a mixture composed of water, glycerol, ethylene glycol, propylene glycol and a stabilizer, etc. When in use, the processor 5 controls the power supply module 4 to supply power to the heating wire, so that the heating wire generates heat. When the heating wire generates heat, it acts on the smoke oil to generate smoke. The generated smoke is discharged through the smoke outlet hole 7 through a smoke transmission pipe communicated with the smoke outlet. The smoke generator 6 is preferably set to be detachable from the beacon positioning device for replacement, and the beacon device can be reused after checking that the sensors in the housing 1 are intact.

[0029] For the convenience of exhausting smoke, further, the smoke outlet of the smoke generator 6 is in one-to-one correspondence and communication with the smoke outlet hole 7 through a plurality of smoke transmission pipes.

[0030] To prevent dust from entering the smoke transmission pipe and the inside of the housing 1 through the smoke outlet hole 7, further, a filter screen 8 is provided in the smoke outlet hole 7. The filter screen 8 can be provided in multiple layers to improve the dust prevention effect, but it is necessary to ensure that the smoke generated by the smoke generator 6 can pass through the filter screen 8.

[0031] To protect the electronic components within the housing 1, the interior of the housing 1 is filled with a cushioning material. The cushioning material fills the gap between the electronic components within the housing 1 and the housing 1, so as to provide better protection for the electronic components within the housing 1. Since the outlet of the smoke generator 6 is connected to the corresponding smoke outlet hole 7 through a smoke pipe, a smoke outlet passage is formed, and the smoke will not be blocked by the cushioning material. The cushioning material can specifically be made of foam plastic, preferably high-density foam plastic in the prior art.

[0032] In some embodiments, the trajectory sensing module 2 includes an inclination angle sensor 201, an azimuth sensor 202, and an acceleration sensor 203. The inclination angle sensor 201, the azimuth sensor 202, and the acceleration sensor 203 are all electrically connected to the processor 5.

[0033] To avoid collisions between the sensors, preferably, there are gaps between the inclination angle sensor 201, the azimuth sensor 202, and the acceleration sensor 203.

[0034] To facilitate the storage of the motion trajectory data acquired by the trajectory sensing module 2, a storage module 9 is further included. The storage module 9 is electrically connected to the processor 5, and the power supply module 4 is also used to supply power to the storage module 9.

[0035] It should be noted that the words representing azimuth in this article, such as up and down, etc., are all set in the Figure 1 direction for the convenience of description and do not have any other specific meanings.

[0036] It also should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that an article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such article or device. Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the article or device including the above elements.

[0037] Specific examples are used in this article to elaborate on the principles and implementation manners of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
