Description

Technical Field

[0001] This utility model relates to the field of geological exploration technology, specifically to a portable exploration device for geological exploration of hydropower stations. Background Technology

[0002] After use, the drill bit of a typical exploration device will have a lot of soil attached to its surface, which is not easy to clean and will affect the use of the device in the next exploration. This reduces the effectiveness of the exploration device. In addition, the soil collected during the exploration process varies in size, and if it is not cleaned in time, it will be inconvenient for soil testing.

[0003] Chinese patent CN219638776U discloses a portable geological exploration device, including a main body. The front of the main body has a feeding port, and a connecting pipe is located on the side. A fixing plate is located at the lower end of the connecting pipe, and a push rod is located at the upper end of the fixing plate. A first motor is located inside the main body, and a drill rod is located at the lower end of the first motor. A cleaning brush is located on the outer side of the drill rod, and a bracket connected to the push rod is located on one side of the cleaning brush. A second motor is located on the side of the first motor. The lower end of the second motor is provided with a rotating shaft, the center of which is provided with a gear assembly. The lower end of the gear assembly is provided with a reciprocating lead screw. The lower end of the rotating shaft is provided with a crushing paddle. The upper end of the frame is provided with a high-pressure nozzle. A connecting plate is provided on one side of the reciprocating lead screw. One end of the connecting plate is connected to a kit. One end of the kit is provided with a limiting member connected to the crushing paddle. The lower end of the rotating shaft is provided with a limiting groove. The inside of the limiting groove is provided with a limiting block connected to the rotating shaft. The lower end of the push rod is provided with a slide block. The surface of the slide block is provided with a sliding groove.

[0004] While the above-mentioned method can clean the drill bit, it requires spraying water onto the drill bit with a high-pressure nozzle. The water flow washes away the dirt by impacting the drill bit. However, this cleaning method has a high water requirement, and the water used to wash the drill bit will flow out directly. During the exploration process, there will inevitably be situations where the exploration site is far away from the water source. If water is needed, it is necessary to go to the water source to fetch water, which is time-consuming, labor-intensive, and has poor endurance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a portable exploration device for geological surveys of hydropower stations. By incorporating a water supply device and a jacking device, the jacking device is activated only when the drill bit rises, turning on the water supply device. Neither the jacking device nor the water supply device requires a separate driver, reducing energy consumption. After the sealing component in the water supply device is opened by the jacking device, the water stored in the water supply tank flows to the cleaning device through a guide rod. The water output of this method is less than that of traditional high-pressure nozzles. Furthermore, a wastewater collection device is installed at the bottom of the cleaning device. After the wastewater settles in the collection device, the upper water is drained back to the water supply device, improving water resource recycling and enhancing the exploration device's operational endurance when far from water sources.

[0006] The technical solution adopted in this utility model is as follows:

[0007] This utility model provides a portable exploration device for geological exploration of hydropower stations, including a shell 1, a drill bit 2 that extends and retracts along the height direction of the shell 1, and a drive device 3 for driving the drill bit 2 to rise, fall and rotate; it also includes a water supply device 4 and a cleaning device 5.

[0008] The cleaning device 5 is located inside the housing 1. When the drill bit 2 retracts into the housing 1, the cleaning device 5 contacts the side wall of the drill bit 2.

[0009] The water supply device 4 is located on the upper part of the cleaning device 5. The water supply device 4 drips water to the cleaning device 5 when the drill bit 2 rises, and stops supplying water when the drill bit 2 stops rising.

[0010] Preferably, the water supply device 4 includes a water supply shell 41 and a sealing assembly 42;

[0011] The water supply shell 41, which contains clean water, is located inside the outer shell 1;

[0012] The sealing component 42 is disposed at the bottom of the water supply shell 41. The sealing component 42 seals the bottom of the water supply shell 41 when the drill bit 2 stops rising, and opens the bottom of the water supply shell 41 when the drill bit 2 rises. The sealing component 42 does not require electric power.

[0013] Preferably, a jacking device 6 that moves vertically and can push open the sealing component 42 is provided at the lower part of the sealing component 42; the jacking device 6 continuously pushes open the sealing component 42 when the drill bit 2 is in the rising state, and stops jacking the sealing component 42 when the drill bit 2 stops rising.

[0014] Preferably, the actuating device 6 includes a corrugated sleeve 62 and an actuating member 63;

[0015] The corrugated sleeve 62 is vertically disposed on one side of the sealing assembly 42. The bottom of the corrugated sleeve 62 is provided with a one-way ventilation assembly 61 that allows outside air to flow into the corrugated sleeve 62. The lower end of the corrugated sleeve 62 remains at a constant height. When the upper end of the corrugated sleeve 62 rises synchronously with the drill bit 2, the one-way ventilation assembly 61 is opened. After the upper end of the corrugated sleeve 62 stops rising with the drill bit 2, the one-way ventilation assembly 61 is closed.

[0016] The actuating member 63 is vertically movable at the lower part of the one-way ventilation component 61. When the one-way ventilation component 61 is open, the actuating member 63 is in the upper stop position, at which time the actuating member 63 pushes open the sealing component 42. When the one-way ventilation component 61 is closed, the actuating member 63 is in the lower stop position, at which time the actuating member 63 disengages from pushing the sealing component 42.

[0017] Preferably, the jacking device 6 includes a guide rod 64, which is fixedly mounted on the push rod 52 of the cleaning device 5 and tilted downward toward the cleaning device 5. The guide rod 64 guides the water flowing out of the water supply shell 41 after the sealing assembly 42 is opened to the cleaning device 5.

[0018] Preferably, a one-way valve 65 is provided on the upper part of the corrugated sleeve 62. When the upper part of the corrugated sleeve 62 descends synchronously with the drill bit 2, the air inside the corrugated sleeve 62 is discharged through the one-way valve 65.

[0019] Preferably, a wastewater collection device 7 is provided below the cleaning device 5, which collects and allows the wastewater falling from the cleaning device 5 to settle.

[0022] This invention incorporates a water supply device and a jacking device. The jacking device is activated only when the drill bit rises, turning on the water supply device. Neither the jacking device nor the water supply device requires a separate driver, reducing energy consumption. After the sealing component in the water supply device is opened by the jacking device, the water stored in the water supply shell flows to the cleaning device through a guide rod. The water output of this method is less than that of traditional high-pressure nozzles. Furthermore, a wastewater collection device is installed at the bottom of the cleaning device. After settling in the wastewater collection device, the water is drained back to the water supply device, improving water resource recycling and enhancing the working endurance of the exploration device when far from water sources.

[0035] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 This utility model provides a portable exploration device for geological exploration of hydropower stations, including a shell 1, a drill bit 2 that extends and retracts along the height direction of the shell 1, and a drive device 3 for driving the drill bit 2 to rise, fall, and rotate; the exploration device also includes a water supply device 4 and a cleaning device 5; the cleaning device 5 is located inside the shell 1, and when the drill bit 2 retracts into the shell 1, the cleaning device 5 contacts the side wall of the drill bit 2; the water supply device 4 is located above the cleaning device 5, and the water supply device 4 drips water to the cleaning device 5 when the drill bit 2 rises, and stops supplying water when the drill bit 2 stops rising.

[0037] When drill bit 2 is needed, drive device 3 drives drill bit 2 to descend and rotate simultaneously. After drilling is completed, drive device 3 drives drill bit 2 to rise. It is worth noting that when drive device 3 drives drill bit 2 to rise and retract into housing 1, drill bit 2 remains in a rotating state. Thus, the surface of drill bit 2 and cleaning device 5 are in a state of relative motion. The structure of drive device 3 is existing technology and will not be described in detail here. There are two cleaning devices 5, which are symmetrically arranged on both sides of drill bit 2. Each cleaning device 5 includes an arc plate 51, an ejector rod 52, and an electromagnetic actuator 53. The arc plate 51 is horizontally movable on one side of drill bit 2. The ejector rod 52 is fixedly located at the end of arc plate 51 away from drill bit 2 along the direction of movement of arc plate 51. The electromagnetic actuator 53 is located at the end of ejector rod 52 away from arc plate 2. At one end of 51, the electromagnetic actuator 53 can drive the ejector rod 52 to extend and retract horizontally. When the electromagnetic actuator 53 drives the ejector rod 52 to extend the arc plate 51, the arc plate 51 contacts the side wall of the drill bit 2. The two cleaning devices 5 operate synchronously, that is, the two arc plates 51 in the two cleaning devices 5 extend synchronously. After extending, the two arc plates 51 can contact the side wall of the drill bit 2 synchronously. The two arc plates 51 form a circular structure. A steel wire cleaning cloth is provided on the contact end of the arc plate 51 and the drill bit 2. During the upward and retraction process of the drill bit 2, the water supply device 4 supplies water to the arc plate 51. In this way, the steel wire cleaning cloth can be wetted, ensuring that the steel wire cleaning cloth on the arc plate 51 will not dry and rub against the side wall of the drill bit 2, avoiding the situation where the arc plate 51 scratches the side wall of the drill bit 2 when cleaning the drill bit 2 with the steel wire cleaning cloth. Because the water supply device 4 uses drip irrigation to supply water, the usage time of the clean water source is extended. This allows the exploration device to clean the drill bit 2 multiple times even when operating away from the water source, thus improving exploration efficiency. Furthermore, the water supply device 4 is activated in a non-electrically driven manner as the drill bit 2 rises, reducing energy consumption.

[0038] Reference Figure 2 and Figures 6-8 The water supply device 4 includes a water supply shell 41 and a sealing component 42. The water supply shell 41, which contains clean water, is located inside the outer shell 1. The sealing component 42 is located at the bottom of the water supply shell 41. The sealing component 42 seals the bottom of the water supply shell 41 when the drill bit 2 stops rising, and opens the bottom of the water supply shell 41 when the drill bit 2 rises. The sealing component 42 does not require electric power.

[0039] The sealing assembly 42 includes a sealing sleeve 421, a spring 422, and a sealing ball 423. The sealing sleeve 421 is vertically installed at the bottom of the water supply shell 41. A water passage groove is formed on the side wall of the sealing sleeve 421. The sealing ball 423 is movable within the sealing sleeve 421 along its extension direction. A gap exists between the upper part of the sealing ball 423 and the end of the sealing sleeve 421. The spring 422 is installed within the gap along the moving direction of the sealing ball 423. The two ends of the spring 422 are fixedly connected to the ends of the sealing ball 423 and the sealing sleeve 421, respectively. The exploration device also has a top... When the drill bit 2 rises and retracts into the outer casing 1, the jacking device 6 lifts the sealing ball 423. The lifted sealing ball 423 compresses the spring 422, so that the water in the water supply shell 41 flows into the sealing sleeve 421 through the water channel and flows out from the bottom of the sealing sleeve 421. After the drill bit 2 stops rising, the jacking device 6 stops lifting the sealing ball 423. The sealing ball 423 falls back under the elastic force of the spring 422, and the sealing ball 423 seals the bottom of the sealing sleeve 421, so that the water in the water supply shell 41 cannot flow out through the bottom of the sealing sleeve 421.

[0040] Reference Figure 6 A jacking device 6 is provided at the lower part of the sealing component 42, which moves vertically and can push the sealing component 42 open. When the drill bit 2 is in the rising state, the jacking device 6 continuously pushes the sealing component 42 open. When the drill bit 2 stops rising, the jacking device 6 stops pushing the sealing component 42 open.

[0041] Reference Figures 6-8 The jacking device 6 includes a corrugated sleeve 62 and a jacking member 63. The corrugated sleeve 62 is vertically arranged on one side of the sealing assembly 42. The bottom of the corrugated sleeve 62 is provided with a one-way ventilation component 61 that allows outside air to flow into the corrugated sleeve 62. The height of the lower end of the corrugated sleeve 62 remains constant. When the upper end of the corrugated sleeve 62 rises synchronously with the drill bit 2, the one-way ventilation component 61 opens. After the upper end of the corrugated sleeve 62 stops rising with the drill bit 2, the one-way ventilation component 61 closes. The jacking member 63 is vertically moved and arranged below the one-way ventilation component 61. When the one-way ventilation component 61 is open, the jacking member 63 is in the upper stop position. At this time, the jacking member 63 pushes open the sealing assembly 42. When the one-way ventilation component 61 is closed, the jacking member 63 is in the lower stop position. At this time, the jacking member 63 disengages from jacking the sealing assembly 42.

[0042] The one-way ventilation assembly 61 includes a ventilation sleeve 611 and a ventilation plate 612. The ventilation sleeve 611 is vertically installed at the bottom of the water supply shell 41 and is located on one side of the sealing sleeve 421. A corrugated sleeve 62 covers the outer periphery of the ventilation sleeve 611, isolating the water in the water supply shell 41 from the ventilation sleeve 611. The bottom of the corrugated sleeve 62 is fixedly connected to the bottom of the water supply shell 41. A ventilation groove 614 is provided on the upper part of the ventilation sleeve 611, and ventilation holes are provided on the side wall of the ventilation sleeve 611. The ventilation plate 612 is slidably installed inside the ventilation sleeve 611 along the extending direction of the ventilation sleeve 611. When the drill bit 2 is at the top of the hole, the pusher 63 is in the upper stop position. When the vent plate 612 is at the bottom of the vent hole, the pusher 63 is in the lower stop position. An extension rod is fixedly installed vertically on the upper part of the vent plate 612. The extension rod passes through the upper part of the vent sleeve 611 and slides with the vent sleeve 611. When the drill bit 2 is not rising, the vent plate 612 is located below the vent hole 613. At this time, the vent plate 612 is located below the vent hole 613. When the drill bit 2 rises, the upper part of the corrugated sleeve 62 rises synchronously with the drill bit 2. The air in the corrugated sleeve 62 forms a negative pressure. Under the action of the negative pressure, the vent plate located in the vent sleeve 611... 612 rises within the vent sleeve 611 along its extension direction. When the vent plate 612 rises above the vent hole 613, outside air can rush into the corrugated sleeve 62. The actuating member 63 has a "U"-shaped structure, with one end fixedly mounted at the bottom of the vent plate 612. Thus, as the upper part of the corrugated sleeve 62 rises with the drill bit 2, the vent plate 612 can drive the actuating member 63 to rise. As long as the drill bit 2 continues to rise, under the negative pressure of the corrugated sleeve 62, the vent plate 612 remains above the vent hole 613, thus the vent plate 612 always drives the actuating member 63 to the upper stop position. At this point, the actuating member 63 lifts the sealing ball 423, causing the sealing ball 423 to disengage from the sealing sleeve 421. Water in the water supply shell 41 can then be discharged from the bottom of the sealing sleeve 421. After the drill bit 2 is cleaned, the drive device 3 stops operating, the drill bit 2 stops rotating and stops rising, and the upper part of the corrugated sleeve 62 no longer rises. Negative pressure is no longer formed inside the corrugated sleeve 62, so the vent plate 612 descends under its own weight. When the vent plate 612 is lower than the vent hole 613, the vent plate 612 stops descending, and the actuating member 63 at the bottom of the vent plate 612 also stops actuating the sealing ball 423.

[0043] Reference Figure 7 The jacking device 6 includes a guide rod 64, which is fixedly mounted on the ejector rod 52 and tilted downward toward the cleaning device 5. The guide rod 64 guides the water flowing out of the supply shell after the sealing assembly 42 is opened to the cleaning device 5.

[0044] By fixing a guide rod 64 on the top moving part 63, the water discharged from the water supply tank 41 can be discharged to the cleaning device 5 through the guide rod 64. If the guide rod 64 is not set, the water discharged from the bottom of the water supply tank 41 through the sealing sleeve 421 will fall vertically, and it cannot be guaranteed that the water in the water supply tank can flow to the cleaning device 5.

[0045] Reference Figure 6 A one-way valve 65 is provided on the upper part of the bellows sleeve 62. When the upper part of the bellows sleeve 62 descends synchronously with the drill bit 2, the air inside the bellows sleeve 62 is discharged through the one-way valve 65.

[0046] If a one-way valve 65 is not installed on the upper part of the bellows sleeve 62, outside air may not be able to enter the bellows sleeve 62 through the one-way valve 65. In this case, a self-sealing occurs in the bellows sleeve 62. This is because the one-way ventilation component 61 at the bottom of the bellows sleeve 62 is unidirectional, meaning that outside air can enter the bellows sleeve 62 through the one-way ventilation component 61, but the air in the bellows sleeve 62 cannot be discharged through the one-way ventilation component 61. If the one-way valve 65 is not installed, the bellows sleeve 62 will self-seale when the drill bit 2 descends. The expansion and contraction of the bellows sleeve 62 will be synchronized with the rise and fall of the drill bit 2, thus preventing the drill bit 2 from descending normally.

[0047] Reference Figure 6 and Figure 8 A wastewater collection device 7 is installed below the cleaning device 5. The wastewater collection device 7 collects the wastewater falling from the cleaning device 5 and allows it to settle.

[0048] The wastewater collection device 7 includes a collection shell 71, which is located at the lower part of the cleaning device 5. The drill bit 2 penetrates the collection shell 71 vertically. An opening is provided at the upper part of the collection shell 71. Wastewater dripping from the cleaning device 5 enters the collection shell 71 through the opening. After entering the collection shell 71, the wastewater is left to stand, and the mud and sand in the wastewater gradually settle to the bottom after standing.

[0049] Reference Figure 1 and Figure 5 Wastewater collection device 7 includes a circulation device 72, which pumps the clear water that has settled in the wastewater collection device 7 back to the water supply device 4.

[0050] The circulation device 72 includes a circulation pipe 721 and a pump body 722. The two ends of the circulation pipe 721 are connected to the water supply shell 41 and the collection shell 71, respectively. The pump body 722 is installed on the circulation pipe 721. The connection between the circulation pipe 721 and the collection shell 71 is higher than the bottom of the collection shell 71. In this way, when the pump body 722 pumps the separated water out of the collection shell 71 through the circulation pipe 721, it will not pump out the sediment at the bottom of the collection shell 71. After the pump body 722 is started, the circulation pipe 721 pumps the clear water in the upper layer of the collection shell 71 back into the water supply shell 41.

[0051] This invention incorporates a water supply device and a jacking device. The jacking device is activated only when the drill bit rises, turning on the water supply device. Neither the jacking device nor the water supply device requires a separate driver, reducing energy consumption. After the sealing component in the water supply device is opened by the jacking device, the water stored in the water supply shell flows to the cleaning device through a guide rod. The water output of this method is less than that of traditional high-pressure nozzles. Furthermore, a wastewater collection device is installed at the bottom of the cleaning device. After settling in the wastewater collection device, the water is drained back to the water supply device, improving water resource recycling and enhancing the working endurance of the exploration device when far from water sources.

[0052] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
