[0058] A pumping mechanism 4, the pumping mechanism 4 comprising a water pump 41, a first connecting pipe 42 and a second connecting pipe 43, the input end of the water pump 41 being connected to the output end of the first valve body 21 through the first connecting pipe 42, and the output end of the water pump 41 being connected to the input end of the second valve body 51 through the second connecting pipe 43;

[0059] The adjusting mechanism 7 includes a connecting shaft 71 and an adjusting assembly 72. The two ends of the connecting shaft 71 respectively penetrate the first valve body 21 and the second valve body 51, and the two ends of the connecting shaft 71 are respectively fixedly connected to the first valve cover 22 and the second valve cover 52. The connecting shaft 71 is rotatably connected to the first valve body 21 and the second valve body 51, respectively. The adjusting assembly 72 is used to drive the connecting shaft 71 to rotate and adjust.

[0060] Among them, when the equipment is in the rainwater diversion mode, the water diversion pipe 13 is connected to the first connecting pipe 42 through the first switching valve 2, and the second connecting pipe 43 is connected to the water supply pipe 6 through the second switching valve 5; when the adjusting component 72 controls the rotation of the connecting shaft 71, the equipment switches from the rainwater diversion mode to the rainwater injection mode; when the equipment is in the rainwater injection mode, the water supply pipe 3 is connected to the first connecting pipe 42 through the first switching valve 2, and the second connecting pipe 43 is connected to the water injection pipe 12 through the second switching valve 5.

[0061] In this embodiment, the water injection pipe 12 is used to provide support for supplementary pumping of rainwater in the water storage range of the tank body 11, so that the interior of the tank body 11 can provide stable and reliable water pumping support when diverting water. The switch adjustment of the water injection pipe 12 is controlled by the second switching valve 5;

[0062] The water diversion pipe 13 is used to extract the extracted rainwater from the tank body 11; when the extracted rainwater from the tank body 11 is extracted, negative pressure begins to be generated inside the tank body 11, so that the tank body 11 extracts rainwater from the rainwater collection area into the tank body 11 through the water diversion pipe 10, thereby realizing stable extraction of collected rainwater. The switch adjustment of the water diversion pipe 13 is controlled by the first switching valve 2.

[0063] The pumping pipe 10 is inserted into the interior of the rainwater source to be extracted, wherein the rainwater source can be ground rainwater or reserved mine water collection, and is mainly used for the extraction and treatment of rainwater;

[0064] The flow-aiding pump 20 is installed on the bottom ground of the rainwater source, wherein the flow-aiding pump 20 is immersed in the water surface of the rainwater source and does not expose the water surface of the rainwater source; it provides a flow-aiding function for the drainage of the rainwater source drawn inside the pumping pipe 10; it is mostly used in an environment where the pumping pipe 10 has a long depth of penetration, and after transportation, it enters the interior of the tank body 11, so that the rainwater resources that need to be drawn can be stably drained toward the interior of the tank body 11.

[0065] In this embodiment, the first valve cover 22 is a cylindrical structure, and the first valve cover 22 is communicated with the first connecting pipe 42 ; the second valve cover 52 is a cylindrical structure, and the second valve cover 52 is communicated with the second connecting pipe 43 .

[0066] The water supply pipe 3 is connected to an external water source to provide support for filling and replenishing the water source in the tank body 11; wherein the external water source can be tap water, drinking water or rainwater resources prepared in advance.

[0067] Combination Figure 3 and Figure 4 In this embodiment, the first through hole 221 is a single-hole structure; the second through hole 521 is a double-hole structure.

[0068] The device includes two modes of use;

[0069] Rainwater diversion mode: the water diversion pipe 13 is in an open state, the water supply pipe 3 is in a closed state, the water injection pipe 12 is in a closed state, and the water delivery pipe 6 is in an open state, so as to facilitate the drainage and transportation of ground / collected rainwater resources;

[0070] Rainwater filling mode: the water diversion pipe 13 is in a closed state, the water supply pipe 3 is in an open state, the water filling pipe 12 is in an open state, and the water delivery pipe 6 is in a closed state, so as to facilitate the replenishment of the rainwater source required for diversion of water into the tank body 11.

[0071] Mode switching principle:

[0072] Combination Figure 2 , Figure 3 and Figure 4 It may be defined that in the initial state, the device is in the rainwater diversion mode. Before the rainwater needs to be extracted, the adjusting component 72 drives the connecting shaft 71 to rotate, and the connecting shaft 71 synchronously drives the first valve cover 22 and the second valve cover 52 to rotate;

[0073] When the first valve cover 22 rotates, the first through hole 221 rotates, so that the water diversion pipe 13 is automatically closed and the water supply pipe 3 is automatically opened; when the second valve cover 52 rotates, the second through hole 521 rotates, so that the water supply pipe 6 is automatically closed and the water injection pipe 12 is automatically opened, so as to first replenish the rainwater required for diversion into the tank body 11;

[0074] Finally, before the collected rainwater is extracted, rainwater is replenished into the tank body 11, so as to automatically replenish rainwater resources; when the mode is switched, the two valve structures are switched synchronously; thereby facilitating the switching of the working mode of the equipment, after the switching, the same pump structure can be used for both the extraction of rainwater and the filling of rainwater; the use of the valve structure and the vacuum use time of the pump are reduced, the full utilization rate of the equipment is improved, and the use cost of the equipment is reduced; the device can realize both the water diversion of rainwater resources with a low suction range (less than 6 meters) and the water injection (also called water feeding) with a high suction range.

[0075] See also Figure 5 The tank body 11 is provided with a manhole 19, and the manhole 19 is staggered with the water diversion pipe 13. The manhole 19 facilitates the later inspection and maintenance of the interior of the tank body 11.

[0076] Please refer again Figure 2 The tank body 11 is provided with a pressure relief valve 14 and a water level sensor 15. The pressure relief valve 14 is connected to the tank body 11, and the water level sensor 15 is aligned with the water storage range of the rainwater for water diversion in the tank body 11. The pressure relief valve 14 is used for exhausting the inside of the tank body 11, and a solenoid valve is provided at the port of the pressure relief valve 14 for switching control of the pressure relief valve 14 (equipped with both manual switch and intelligent switch).

[0077] In this embodiment, a drainage pipe 17 is provided at the bottom of the tank body 11, and an independent control valve body is provided on the drainage pipe 17. The input end of the drainage pipe 17 is connected to the inside of the tank body 11 and the water storage range, which is convenient for regular drainage maintenance of the tank body 11 and cleaning impurities carried in the rainwater collected during the water diversion process.

[0078] Please refer again Figure 2 A partition 16 is fixedly arranged in the tank body 11, and an overflow hole 161 is opened on the partition 16. An overflow cavity 110 is formed between the tank body 11 and the partition 16. An overflow pipe 18 is arranged on the tank body 11, and the overflow pipe 18 is connected with the overflow cavity 110. When the rainwater source is filled in the tank body 11, the overflow rainwater source is isolated from the filling rainwater source, and an independent storage area is provided for the overflow rainwater.

[0079] In this embodiment, the manhole 19 passes through the partition 16 and communicates with the tank body 11 , so that the manhole 19 directly enters between the tank body 11 and the partition 16 after opening, and does not communicate with the overflow chamber 110 .

[0080] In this embodiment, the output end of the water pumping pipe 10 is located above the horizontal height of the overflow hole 161 ; when water is added, the water first overflows the overflow hole 161 and does not exceed the height of the water pumping pipe 10 .

[0081] Please refer again Figure 2 The adjustment assembly 72 includes a telescopic member 721, a toothed plate 722, a gear 723, a connecting rod 724, a transmission member 725, and a hinge shaft 726;

[0082] The telescopic member 721 is fixed on the tank body 11, the tooth plate 722 is fixed on the output end of the telescopic member 721, the gear 723 is meshed and installed on the tooth plate 722, the gear 723 is fixedly connected to the connecting shaft 71, one end of the connecting rod 724 passes through the partition 16 and the tank body 11 in sequence and is fixed on the tooth plate 722, one end of the transmission member 725 is hinged to the other end of the connecting rod 724, and the other end of the transmission member 725 is hinged to the hinge shaft 726, a lifting cover 73 is slidably installed in the partition 16, and the hinge shaft 726 is fixed on the lifting cover 73;

[0083] Among them, when the equipment is in rainwater diversion mode, the lifting cover 73 is aligned with the range of the overflow hole 161, and the overflow hole 161 is closed; when the equipment is in rainwater injection mode, the lifting cover 73 and the overflow hole 161 are staggered and distributed, and the overflow hole 161 is open.

[0084] In this embodiment, the telescopic member 721 may be an electric telescopic rod or a telescopic cylinder, which provides a power source for the telescopic adjustment of the tooth plate 722 .

[0085] A mechanical seal is used at the connection between the connecting rod 724 and the partition 16 , and a mechanical seal is used at the connection between the connecting rod 724 and the tank body 11 , so that the connecting rod 724 can be stably telescopically adjusted on the partition 16 and the tank body 11 .

[0086] When it is necessary to control the rotation of the connecting shaft 71, the telescopic member 721 is started, and the telescopic member 721 drives the tooth plate 722 to extend. When the tooth plate 722 extends, it drives the gear 723 to rotate, and the gear 723 drives the connecting shaft 71 to rotate. The connecting shaft 71 simultaneously drives the first valve cover 22 and the second valve cover 52 to rotate and adjust;

[0087] When the tooth plate 722 extends, the connecting rod 724 is driven to extend. The connecting rod 724 drives the hinge shaft 726 and the lifting cover 73 to move upward as a whole through the transmission member 725. When the lifting cover 73 moves upward, the overflow hole 161 is automatically opened. On the one hand, the overflow hole 161 is automatically opened and closed while the device is adjusting the mode.

[0088] Finally, when the rainwater diversion equipment needs to be adjusted and applied, the first switching valve 2 and the second switching valve 5 modes are synchronously switched under the action of the same power drive, and the overflow hole 161 is automatically opened during the switching process.

[0089] The working principle of the pump-front mounted water diversion device for mine water collection provided in this embodiment is as follows:

[0091] At this time, the water pump 41 provides rainwater extraction and delivery support for the water delivery pipe 6;

[0092] Combination Figure 6 From (a1) to (a2), when the first switching valve 2 and the second switching valve 5 need to be adjusted, the telescopic member 721 is started, the telescopic member 721 drives the toothed plate 722 to extend, the toothed plate 722 drives the gear 723 to rotate counterclockwise, and the connecting shaft 71 rotates counterclockwise synchronously;

[0093] Combination Figure 6 From (b1) to (b2), the first valve cover 22 is driven to rotate counterclockwise while the connecting shaft 71 rotates, and the first valve cover 22 drives the first through hole 221 to rotate counterclockwise, so that the first through hole 221 is gradually separated from the output end of the water diversion pipe 13;

[0095] Combination Figure 7From (d1) to (d2), the tooth plate 722 extends while driving the connecting rod 724 to extend synchronously, and the connecting rod 724 pushes the hinge shaft 726 to move upward synchronously through the transmission member 725, and drives the lifting cover 73 to move upward while the hinge shaft 726 moves upward. During the upward movement of the lifting cover 73, the overflow hole 161 gradually opens;

[0098] Combination Figure 6 From (b2) to (b3), the connecting shaft 71 continues to drive the first valve cover 22 to rotate counterclockwise, and the first through hole 221 rotates counterclockwise and is aligned from the range of the water diversion pipe 13 to the range of the water supply pipe 3;

[0099] Combination Figure 6 From (c2) to (c3), the connecting shaft 71 continues to drive the second valve cover 52 to rotate counterclockwise, and the second through hole 521 rotates counterclockwise and is aligned from the range of the water supply pipe 6 to the range of the water injection pipe 12;

[0100] Combination Figure 7 From (d2) to (d3), the connecting rod 724 continues to extend, and the connecting rod 724 pushes the hinge shaft 726 to continue to move upward through the transmission member 725, and the lifting cover 73 continues to move upward. During the upward movement of the lifting cover 73, the overflow hole 161 is fully opened, so that the water pump 41 can provide support for pumping and filling water to the water injection pipe 12.

[0101] like Figure 6 (a4), (b3) and (c3) in Figure 7 As shown in (d3), after the mode is switched, the device is in the rainwater injection mode, the tooth plate 722 and the gear 723 are in a separated state, the first through hole 221 is connected to the water supply pipe 3, the second through hole 521 is connected to the water injection pipe 12, and the overflow hole 161 is in an open state;

[0102] Finally, in the process of adjusting the rainwater diversion equipment, the modes of the first switching valve 2 and the second switching valve 5 are switched, and the lifting cover 73 is synchronously moved upward while switching to realize the automatic opening of the overflow hole 161 to meet the needs of rainwater delivery and rainwater injection.

[0103] Embodiment 2:

[0104] Please refer again Figure 8 Based on the first embodiment of the present invention, a water diversion device installed in front of a pump for mine water collection is provided. The second embodiment of the present invention provides another water diversion device installed in front of a pump for mine water collection. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0105] Specifically, the difference of the pre-pump mounted water diversion device for mine water collection provided by the second embodiment of the present invention is that the adjusting mechanism 7 also includes a driving member 74, a rotating cover 75 and a cleaning brush 76, the rotating cover 75 is rotatably installed on the water suction pipe 10, the cleaning brush 76 is fixed on the rotating cover 75, and the bottom of the cleaning brush 76 is slidably connected to the bottom of the tank body 11; the driving member 74 is used to drive the rotating cover 75 to rotate and adjust.

[0106] Since rainwater is prone to carry plankton or dust after falling and being collected, when the bottom of the tank body 11 needs to be cleaned, the driving member 74 can control the rotating cover 75 to rotate synchronously, and the rotating cover 75 drives the cleaning brush 76 to rotate. When the cleaning brush 76 rotates, it can adaptively clean the plankton or dust inside the tank body 11, thereby reducing the residual dirt carried in the rainwater after water diversion.

[0107] In an optional embodiment, the driving member 74 may be an independent motor transmission structure to provide a power source for the rotation adjustment of the rotating cover 75 .

[0108] In another optional embodiment, a transmission groove 751 is opened on the rotating cover 75, one end of the driving member 74 is fixedly connected to the lifting cover 73, and the other end of the driving member 74 is inserted into the transmission groove 751 and is transmission-connected to the lifting cover 73.

[0109] It is convenient to drive the driving member 74 upward while the lifting cover 73 moves upward. When the driving member 74 moves upward, it drives the rotating cover 75 to rotate and adjust through the transmission slot 751. When the rotating cover 75 rotates, it drives the cleaning brush 76 to rotate synchronously. The cleaning brush 76 realizes adaptive cleaning and maintenance of the bottom of the tank body 11.

[0110] Finally, in the process of adjusting the rainwater diversion device, the first switching valve 2 and the second switching valve 5 are switched, the rotating cover 75 is moved upward, and the cleaning brush 76 is rotated, so as to facilitate the use of the diversion mechanism 1.

[0111] In an optional embodiment, the driving member 74 may be an electric telescopic rod, and the shaft end of the electric telescopic rod is a round shaft structure, which is inserted into the transmission groove 751. It is convenient for the driving member 74 to dock and separate from the transmission groove 751, so as to select whether to perform rotation cleaning according to the use requirements. When it is not necessary to clean the bottom of the tank body 11, the shaft end is controlled by the driving member 74 to shrink and separate from the transmission groove 751, so as to facilitate normal adjustment and use of the device when cleaning is not required.

[0112] The working principle of the water diversion device installed in front of the pump for mine water collection provided in this embodiment is as follows:

[0113] like Fig. 9 As shown in (e1) and (f1), it may be defined that in the initial state, the driving member 74 is located at the bottom end of the transmission groove 751, and the cleaning brush 76 is attached to the bottom of the tank body 11;

[0114] Combination Fig. 9 In (e1) to (e2) to (e3) and (f1) to (f2) to (f3), when the lifting cover 73 moves upward, the driving member 74 moves upward and drives the rotating cover 75 to rotate clockwise through the transmission groove 751. When the rotating cover 75 rotates, the cleaning brush 76 is driven to rotate synchronously, and the automatic cleaning and maintenance of the tank body 11 is realized when the overflow hole 161 is opened;

[0115] like Fig. 9 As shown in (e3) and (f3), the driving member 74 is located at the top of the transmission groove 751, and the cleaning brush 76 changes its position and fits on the bottom of the tank body 11; so as to achieve adaptive cleaning of the tank body 11.

[0116] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
