Description

Technical Field

[0001] The invention relates to the technical field of water diversion equipment, in particular to a water diversion equipment for irrigation. Background Art

[0002] In the fields of agriculture, forestry and gardening, after the vegetation is planted, in order to ensure the early survival rate of the vegetation, it is usually necessary to actively irrigate. In this process, water diversion equipment is needed;

[0003] Agricultural water sources are generally rivers, ponds, etc., while forestry and gardens far away from water sources usually build water storage facilities such as reservoirs, which are generally open-air structures. Regardless of ponds, rivers or reservoirs, their water levels are easily affected by the weather, and in most cases, there will be floating impurities such as fallen leaves on the water surface. Such large impurities will cause the filtering mechanism of the water diversion equipment to be blocked, and more mud and sand will be deposited on the bottom of the water. During the water diversion process, a large amount of mud and sand will enter the water pump with the water flow, which will reduce the life of the water pump.

[0004] Meanwhile, in the prior art, most water diversion equipment only performs simple filtering treatment on the end of the water pump pipe. Large floating objects on the water surface will clog the filtering components, while small silt will enter the water pump. If multiple filtrations are performed, the flow rate of the water diversion equipment will be affected, resulting in prolonged water diversion time. In order to solve the above problems, a water diversion equipment for irrigation is proposed. Summary of the invention

[0059] Combine the following Figures 1 to 7 As shown, an embodiment of the present invention provides a water diversion device for irrigation, comprising:

[0060] A shell 201, wherein a net tube 501 is disposed in the shell 201, and two ends of the net tube 501 respectively penetrate the top and bottom of the shell 201;

[0061] A first cover body 202 and a second cover body 203, wherein the first cover body 202 is arranged on the top of the housing 201, and the second cover body 203 is arranged on the bottom of the housing 201, and a plurality of connecting rods 204 are fixed between the first cover body 202 and the second cover body 203, and each connecting rod 204 penetrates the housing 201, and each connecting rod 204 is slidably connected to the housing 201;

[0062] A first mesh plate 502 and a second mesh plate 503, wherein the first mesh plate 502 is fixed to the top of the mesh cylinder 501, and the second mesh plate 503 is fixed to the bottom of the mesh cylinder 501, and the mesh numbers of the first mesh plate 502 and the second mesh plate 503 are smaller than the mesh number of the mesh cylinder 501;

[0063] A second hose 701, the second hose 701 is fixed on the top of the first mesh plate 502, and the second hose 701 passes through the bottom of the first mesh plate 502;

[0064] A water pumping pipe 101, which is arranged through the top of the first cover body 202, and is connected to the second hose 701, and a side wall of the water pumping pipe 101 is fixedly sleeved with an air bag 102;

[0065] A connecting seat 702, the connecting seat 702 is arranged in the net tube 501, and two third hoses 705 are arranged through the side wall of the connecting seat 702, and the two third hoses 705 both penetrate the side wall of the net tube 501;

[0066] Two adjustment components, both of which are fixed on the side wall of the connecting seat 702, and both of which are fixed to the first cover body 202, and the adjustment components are used to adjust the height of the first cover body 202 and the connecting seat 702, so that the first cover body 202 and the housing 201 are separated and the connecting seat 702 is connected to the second hose 701;

[0067] A cleaning component is disposed in the net cylinder 501 and is used for cleaning the net cylinder 501 .

[0068] During the water diversion process, if the device is suspended in the water and there is a certain distance from the bottom of the water, the first cover body 202 is restricted by the adjusting component. At this time, the top of the shell 201 is sealed by the first cover body 202. Therefore, during the water diversion process, the water flows into the net tube 501 through the second mesh plate 503, and then is directly pumped out by the water pump through the second hose 701 and the water pump 101. In this state, it can effectively prevent floating impurities on the water surface from clogging the second mesh plate 503;

[0069] When the device is close to the bottom of the water, the first cover body 202 rises through the operation of the adjusting component. At this time, the second cover body 203 is against the shell 201 through the action of the connecting rod 204, so that water can enter the net tube 501 through the first mesh plate 502. In the process of the adjusting component driving the first cover body 202 to rise, the connecting seat 702 is also driven to rise, so that the connecting seat 702 enters the second hose 701. At this time, when the water pump is working, the water is initially filtered by the first mesh plate 502, and then filtered twice by the net tube 501, and enters between the shell 201 and the net tube 501, so as to avoid a large amount of mud and sand being pumped into the water pump when the device is close to the bottom of the water, thereby ensuring the working life of the water pump.

[0070] Further, the adjustment component includes:

[0071] The ear plate 704 is fixed on the side wall of the connecting seat 702. The top of the ear plate 704 is fixed with a rod body 601. The rod body 601 passes through the first mesh plate 502 and the top inner wall of the first cover body 202 and is fixed. The side wall of the rod body 601 is provided with a horizontal limiting hole 608, and the side wall of the rod body 601 is provided with a vertical groove 603;

[0072] A first spring 602, one end of the first spring 602 is fixed to the top inner wall of the first cover body 202, and the other end of the first spring 602 is fixed to the top of the first mesh plate 502;

[0073] The limiting unit is arranged at the bottom of the first mesh plate 502 , and is used to fix the rod body 601 .

[0074] When the limiting unit limits the rod 601 , the first spring 602 is compressed and the first cover 202 contacts the top of the shell 201 . When the limiting unit releases the limit on the rod 601 , the first cover 202 moves away from the shell 201 under the action of the first spring 602 .

[0075] Furthermore, the restriction unit includes:

[0076] A second support plate 609, the second support plate 609 is fixed to the bottom of the first mesh plate 502, and a round hole is opened on the side wall of the second support plate 609;

[0077] The limiting rod 610 is slidably disposed in the circular hole, and the limiting rod 610 and the limiting hole 608 are adapted; an iron plate 606 is fixed to one end of the limiting rod 610, and the other end of the limiting rod 610 is a spherical structure;

[0078] A second spring 607, one end of the second spring 607 is fixed to the iron plate 606, and the other end of the second spring 607 is fixed to the second support plate 609;

[0079] The first support plate 604 is fixed at the bottom of the first mesh plate 502 near the iron plate 606 , and an electromagnet 605 is fixed to the side wall of the first support plate 604 .

[0080] During the upward and downward movement of the rod body 601, the limiting rod 610 is always in contact with the rod body 601 through the groove 603, and the second spring 607 is in a compressed state at this time. When the rod body 601 is lowered to a suitable position, the limiting rod 610 enters the limiting hole 608 under the action of the second spring 607 to fix the rod body 601.

[0081] When the electromagnet 605 is turned on, the limiting rod 610 is moved away from the limiting hole 608 under the action of the magnetic force, so that the rod body 601 can slide normally.

[0082] Furthermore, a ring plate 703 is fixedly mounted on the side wall of the connection seat 702 , and the ring plate 703 is located above the two third hoses 705 .

[0083] When the connecting seat 702 enters the second hose 701 , the annular plate 703 can provide a certain degree of sealing effect for the second hose 701 and the connecting seat 702 .

[0084] Further, the cleaning component includes:

[0085] Bracket 801, bracket 801 is fixed on the inner wall of net tube 501, and a mounting hole is opened on the top of bracket 801;

[0086] A hollow shaft 802, the hollow shaft 802 is rotatably disposed in the mounting hole;

[0087] Two adsorption mechanisms, the two adsorption mechanisms are symmetrically arranged on the side wall of the hollow shaft 802, and the adsorption mechanisms include a plurality of adsorption units;

[0088] The negative pressure mechanism is fixed on the top of the second mesh plate 503 , and the negative pressure mechanism is connected to the hollow shaft 802 .

[0089] Through the negative pressure mechanism and the adsorption mechanism, when the hollow shaft 802 rotates, the mud and sand on the inner wall of the net cylinder 501 can be adsorbed to achieve the cleaning work of the net cylinder 501.

[0090] Further, the adsorption unit comprises:

[0091] A connecting pipe 803, which penetrates and is fixed on the side wall of the hollow shaft 802;

[0092] A plurality of tube bodies 804, wherein the plurality of tube bodies 804 are fixed to and communicated with the connecting tube 803;

[0093] A negative pressure seat 805, the negative pressure seat 805 and the plurality of tubes 804 are fixed and connected, and an opening end of the negative pressure seat 805 is close to the inner wall of the net tube 501;

[0094] The annular seat 806 is rotatably disposed at the bottom end of the hollow shaft 802, and the annular seat 806 is rotatably connected to the hollow shaft 802, and the negative pressure mechanism is connected to the annular seat 806;

[0095] The connecting frame 807 is fixed on the inner wall of the hollow shaft 802 , a connecting shaft 808 is fixed on the bottom of the connecting frame 807 , a plurality of blades 809 distributed at equal distances are fixed on the side wall of the connecting shaft 808 , and the plurality of blades 809 are all located in the annular seat 806 .

[0096] When the negative pressure mechanism is working, water enters through the end of the negative pressure seat 805, then enters the connecting pipe 803 through each tube body 804, uniformly flows to the hollow shaft 802, and finally enters the negative pressure mechanism through the annular seat 806 and the electromagnetic valve 304. In this process, the sediment attached to the net tube 501 is adsorbed by the water flow and uniformly collected in the negative pressure mechanism;

[0097] When water flows through the annular seat 806 , the connecting shaft 808 is driven to rotate through the blades 809 , and then the hollow shaft 802 is driven to rotate through the connecting frame 807 , so that each negative pressure seat 805 rotates, increasing the cleaning area to improve the filtering effect of the net cylinder 501 .

[0098] Furthermore, the negative pressure mechanism includes:

[0099] A support tube 305 is fixed through the top of the second mesh plate 503. A negative pressure bottle 303 is fixed on the top of the support tube 305. A one-way valve is arranged inside the support tube 305.

[0100] The solenoid valve 304 is fixed at the bottom of the annular seat 806 , and the solenoid valve 304 and the annular seat 806 are communicated.

[0101] Furthermore, a first hose 302 is provided at the bottom of the support tube 305 , and the first hose 302 passes through the bottom of the second cover body 203 , a sealing cover 301 is provided at the bottom of the first hose 302 , and an underwater ranging sensor 4 is provided at the bottom of the sealing cover 301 .

[0102] Furthermore, a box body 205 is provided at the bottom of the second cover body 203 , and a battery and a single-chip microcomputer are provided in the box body 205 . The single-chip microcomputer is electrically connected to the underwater distance measuring sensor 4 , the solenoid valve 304 and the electromagnet 605 .

[0103] The specific working method is: when in use, first press the first cover body 202 to make the first cover body 202 contact the shell 201. In this process, the second cover body 203 is moved away from the second mesh plate 503 through the action of the connecting rod 204, and the connecting seat 702 is driven away from the second hose 701 through the rod body 601 and the ear plate 704. During the downward sliding of the rod body 601, the spherical end of the limiting rod 610 slides in the groove 603 until the limiting rod 610 enters the limiting hole 608. At this time, under the action of the second spring 607 in a compressed state, the iron plate 606 and the limiting rod 610 are driven to move, so that the limiting rod 610 enters the limiting hole 608. The rod body 601 is fixed by the limiting rod 610 and the limiting hole 608. During the contact between the first cover body 202 and the shell 201, the first spring 602 is compressed.

[0104] After the above operations, the device status is as follows Figure 1 As shown;

[0105] Open the sealing cover 301, connect the first hose 302 to the vacuum pump, and pump the negative pressure bottle 303 into a highly negative pressure state through the first hose 302, the support tube 305 and the one-way valve in the support tube 305. Then fill the air bag 102 with gas, connect the water pump 101 to the water pump through the extension tube, and finally put the whole device into the water source;

[0106] By adjusting the amount of gas inside the airbag 102 and coordinating the weight of the battery in the box body 205, the device is suspended in the water and kept at a certain height from the water surface, and then the water pump can be turned on to start water diversion;

[0107] When water is diverted, the water pump works to generate negative pressure at the second hose 701. Since the top of the housing 201 is sealed by the first cover 202, water enters through the second mesh plate 503 at the bottom of the mesh tube 501. That is, in this state, water enters the second hose 701 after being filtered by the second mesh plate 503, and is then pumped out by the water pump through the water pumping pipe 101. Since the device is suspended in the water at this time and the second mesh plate 503 is at the lower end of the device, floating objects on the water surface will not cause the second mesh plate 503 to be blocked. In addition, since the sediment is mainly deposited at the bottom of the water, the sediment entering the water pump is also less. Therefore, in this state, the flow rate output by the water pump can be guaranteed, and the water pump will not be damaged due to a large amount of sediment.

[0108] If the water depth of the water source is shallow due to weather reasons, after a certain period of water diversion, the device gradually approaches the bottom of the water. At this time, the distance between the device and the bottom of the water is detected in real time through the underwater ranging sensor 4. When the gap between the device and the bottom of the water is small, in order to prevent the water flow at the second mesh plate 503 from carrying mud and sand into the water pump, the single-chip microcomputer turns on the switch of the electromagnet 605 to adsorb the iron plate 606. The movement of the iron plate 606 drives the limiting rod 610 to move, so that the limiting rod 610 is away from the limiting hole 608. When the limiting rod 610 is away from the limiting hole 608, the first spring 602 in the compressed state drives the first cover body 202 to rise. During the rising process of the first cover body 202, the second cover body 203 is driven to rise through the connecting rod 204. The second cover body 203 and the bottom of the shell 201 are in conflict with each other, so that water enters the net cylinder 501 through the first mesh plate 502, so as to increase the distance between the water inlet position of the device and the bottom of the water. In addition, during the rising process of the first cover body 202, the connecting seat 702 is driven to rise by the rod body 601 and the ear plate 704 until the connecting seat 702 enters the second hose 701. At this time, the second hose 701 and the connecting seat 702 are sealed by the annular plate 703, so that during the operation of the water pump, water enters the net cylinder 501 through the first mesh plate 502, and then enters the gap between the shell 201 and the net cylinder 501 through the filtration of the net cylinder 501, and then enters the connecting seat 702 through the third hose 705, and finally enters the water pump through the second hose 701 and the water suction pipe 101. Therefore, when the device is close to the bottom of the water, a large amount of sediment is prevented from entering the water pump by increasing the filtering effect, so as to ensure the working life of the water pump.

[0109] Since the device is close to the bottom of the water, mud and sand will inevitably cause the net tube 501 to be blocked. If it is found that the flow rate drops significantly during the water diversion process, the switch of the solenoid valve 304 can be turned on. After the solenoid valve 304 is turned on, due to the high negative pressure state inside the negative pressure bottle 303, the water in the net tube 501 enters through the end of the negative pressure seat 805, and then enters the connecting pipe 803 through each tube body 804, flows uniformly to the hollow shaft 802, and finally enters the negative pressure bottle 303 through the annular seat 806 and the solenoid valve 304. When the water flows through the annular seat 806, the connecting shaft 808 is driven to rotate through the blade 809, and then the hollow shaft 802 is driven to rotate through the connecting frame 807, so that each negative pressure seat 805 rotates, and the mud and sand on the inner wall of the net tube 501 are adsorbed to improve the filtering efficiency of the net tube 501, thereby ensuring the efficient water diversion work;

[0110] During maintenance, the sealing cover 301 can be opened, the high-pressure water pump and the first hose 302 can be connected, and the device can be put into water in a state where the first cover body 202 is away from the shell 201 and the second cover body 203 is in contact with the shell 201. When the high-pressure water pump is working, water enters the gap between the shell 201 and the net cylinder 501 through the suction pipe 101, the second hose 701, the connecting seat 702 and the third hose 705, and then passes through the net cylinder 501, and then enters the annular seat 806 through the negative pressure seat 805, the tube body 804, the connecting pipe 803, and the hollow shaft 802, so that the hollow shaft 802 rotates, and finally is pumped out by the high-pressure water pump through the negative pressure bottle 303, the support tube 305, the one-way valve on the support tube 305, and the first hose 302, so as to realize the backwashing of the net cylinder 501, realize the all-round and thorough cleaning of the net cylinder 501, and reduce the tediousness of the maintenance work of the device.
