Description

Technical Field

[0001] The invention relates to the technical field of silt removal equipment, and in particular to an underwater silt removal device for anti-clogging water conservancy projects. Background Art

[0002] When cleaning the silt in the river channel, workers usually drain the water and then use high-pressure water guns to disperse the silt. After diluting it into mud, they use mud pumps to extract the mud.

[0003] However, in the process of impacting the silt with a high-pressure water gun, when the silt layer has a certain thickness, the silt in the upper layer is dispersed and diluted into mud. Due to the obstruction of the upper mud, the water flow has a poor effect on dispersing the silt in the lower layer. If the water gun nozzle is directly inserted into the silt and sprayed downward, the downward sprayed water flow will make it difficult for the silt to move horizontally over a large range, resulting in the silt being repeatedly impacted in situ, making it difficult to disperse and carry away the silt.

[0004] When the silt is harder and needs to be impacted with greater water pressure, the reaction force generated by the water gun nozzle when it sprays out greater water pressure is also greater. It is difficult to hold the high-pressure water gun manually to stabilize it, and it may even slip out of the hand, which can easily cause certain dangers to the workers. Summary of the invention

[0005] In order to overcome the disadvantages that when the water gun nozzle is inserted into the silt for downward spraying, the silt will be repeatedly impacted in situ, making it difficult to disperse and carry away the silt; when the water pressure is high, it is difficult to manually hold the high-pressure water gun to stabilize it, and it is easy to slip out of the hand, the present invention provides an underwater dredging device for water conservancy projects that is anti-clogging.

[0006] The technical solution of the present invention is: a bottom silt clearing device for anti-clogging water conservancy projects, comprising a water pipe; the water pipe is connected to an external water pump through a pipeline; it also comprises a connecting tube, a sliding sleeve, a nozzle, a connecting pipe, a connecting frame, a first block, a second block, a support rod and a supporting plate; one end of the outer side of the water pipe is rotatably connected to the connecting tube, and a first handle is provided on the connecting tube; the water pipe is slidably connected to the sliding sleeve, and a second handle is provided on the sliding sleeve; a nozzle for flushing silt is fixedly connected to the connecting tube; a connecting pipe is fixedly connected to the water pipe, and the connecting pipe is located inside the nozzle; the connecting pipe is connected to the connecting frame; the connecting frame is fixedly connected to the first block through the connecting rod; a second block for adjusting the pressure of the sprayed water flow is fixedly connected to the nozzle of the nozzle; a number of evenly distributed through holes are provided on the first block and the second block; a support rod for supporting and stabilizing the water pipe is rotatably connected to the sliding sleeve, and the second handle is fixedly connected to the support rod; an abutment plate is fixedly connected to the lower side of the support rod.

[0007] More preferably, it also includes a sealing ring; a sealing ring is slidably connected to the outer side of the connecting pipe; a plurality of water outlets are opened on the connecting pipe; a plurality of through grooves are opened on the nozzle; a connecting frame is fixedly connected to the sealing ring, the connecting frame is cross-shaped, and the connecting frame passes through the water outlet; an extrusion plate is arranged on the outer side of the sealing ring, and the extrusion plate passes through the through groove.

[0008] More preferably, it further comprises a fixing rod; a plurality of fixing rods are fixedly connected to the lower side of the abutment plate.

[0009] More preferably, both the first handle and the second handle are covered with an anti-slip layer.

[0010] More preferably, the nozzle is configured to be conical in shape.

[0011] More preferably, the abutting plate is in an arc shape.

[0012] More preferably, a suction pipe is further included; the suction pipe is fixedly connected to the abutment plate, the suction pipe is connected to an external mud pump through a pipeline, and the pipe mouth of the suction pipe passes through the abutment plate.

[0013] More preferably, a through opening is provided on the abutting plate; the inner diameter of the through opening is larger than the outer diameter of the nozzle.

[0014] More preferably, a cleaning plate is further included; the cleaning plate is detachably plugged into the lower side of the abutment plate, and all the fixing rods penetrate the cleaning plate.

[0015] More preferably, two pull rings are provided on the cleaning plate.

[0016] Beneficial effects: The present invention realizes that when it is necessary to disperse the sludge at different distances, the first handle can be twisted to rotate the second block, so that the flow channel formed between the through hole on the second block and the through hole on the first block is reduced, thereby increasing the water pressure sprayed by the nozzle, and then increasing the distance of the water flow sprayed by the nozzle, so that the sludge at a long distance can be dispersed, thereby effectively facilitating manual operation without the need for users to move frequently; The nozzle and its connected parts are manually driven to be inserted downward into the silt. During the process of the nozzle being inserted downward into the silt, the blocking ring is pushed upward under the blocking and squeezing of the squeezing plate by the silt, so that the blocking ring releases the blocking of the water outlet, so that the water flow can pass through the water outlet and the through groove in turn, and then be sprayed around the nozzle to achieve the operation of dispersing the silt beside the nozzle, effectively increasing its range of action, and thus effectively enhancing the dispersing effect of the lower layer of silt. At the same time, the water flow sprayed from the water outlet can be used to carry out targeted impact on the silt in the stone cracks, thereby effectively ensuring the dispersing effect of the silt; When the silt is hard and needs to be impacted with a large water pressure, the abutment plate can be placed against the ground and the foot can be placed on the upper side of the abutment plate. When the silt is impacted with water jets through the nozzle, the water pipe can be supported and abutted by the support rod and the abutment plate to prevent the user from losing the grip due to excessive water pressure, thereby effectively ensuring the user's safety. The fixing rod can be used to enhance the grip of the abutment plate to effectively prevent the abutment plate from slipping. When the silt is dispersed by spraying water through the nozzle, the dispersed silt can be pumped through the suction pipe, so that the dispersed silt can be pumped away in time after being dispersed, avoiding the dispersed silt to continue to accumulate in the original place and affect the activities of users, and other aquatic plants, garbage and other debris in the silt can be intercepted by the fixed rod, effectively preventing the debris from being sucked into the suction pipe and causing the suction pipe to be blocked; By inserting the nozzle into the through opening, when the nozzle is inserted into the silt to impact the silt, the dispersed silt can be promptly sucked away through the suction pipe to prevent it from continuing to accumulate in place and blocking the water flow continued to be sprayed from the nozzle, thereby effectively ensuring the nozzle's effect of dispersing the silt, and the small stones underneath can be fixed by a fixing rod to prevent the small stones from being washed away by the water flow or sucked into the suction pipe.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] Example 1 A water conservancy project anti-clogging underwater dredging device, such as Figure 1-Figure 5 As shown, it includes a water pipe 1; the water pipe 1 is connected to an external water pump through a pipeline; It also includes a connecting tube 2, a sliding sleeve 3, a nozzle 4, a connecting pipe 5, a connecting frame 7, a first stopper 8, a second stopper 9, a support rod 101 and an abutment plate 102; one end of the outer side of the water pipe 1 is rotatably connected to the connecting tube 2, and a first handle 2001 is provided on the connecting tube 2; the sliding sleeve 3 is slidably connected to the water pipe 1, and a second handle 3001 is provided on the sliding sleeve 3; the nozzle 4 is fixedly connected to the left side of the connecting tube 2; the connecting pipe 5 is fixedly connected to the left side of the water pipe 1, and the connecting pipe 5 is located inside the nozzle 4; the connecting frame 7 is connected to the connecting pipe 5; the connecting frame 7 is fixedly connected to the first stopper 8 through the connecting rod; the second stopper 9 is fixedly connected to the nozzle of the nozzle 4; a number of evenly distributed through holes are provided on the first stopper 8 and the second stopper 9; the support rod 101 is rotatably connected to the sliding sleeve 3, and the second handle 3001 is fixedly connected to the support rod 101; the abutment plate 102 is fixedly connected to the lower side of the support rod 101.

[0021] It also includes a sealing ring 6; the sealing ring 6 is slidably connected to the outer side of the connecting pipe 5; the connecting pipe 5 is provided with four water outlets 5001 in a circular array; the nozzle 4 is provided with four through grooves 4001 in a circular array; the connecting frame 7 is fixedly connected to the sealing ring 6, the connecting frame 7 is cross-shaped, and the connecting frame 7 passes through the water outlet 5001; an extrusion plate 6001 is arranged on the outer side of the sealing ring 6, and the extrusion plate 6001 passes through the through groove 4001, and the water outlet 5001 is initially blocked by the sealing ring 6.

[0022] It also includes fixing rods 103 ; a plurality of fixing rods 103 are fixedly connected to the lower side of the abutment plate 102 .

[0023] The first handle 2001 and the second handle 3001 are both covered with an anti-slip layer to facilitate manual gripping.

[0024] The nozzle 4 is configured to be conical in shape to reduce the difficulty of inserting the nozzle 4 into the sludge.

[0025] The abutting plate 102 is arc-shaped, so that when the abutting plate 102 is tilted, it can still fit well with the ground.

[0026] During operation, the user can hold the second handle 3001 with the right hand and the first handle 2001 with the left hand, so that the connecting tube 2 and the parts connected thereto are located on the right side of the body, and then adjust the orientation of the connecting tube 2 and the parts connected thereto by holding the second handle 3001 and the first handle 2001, so that the nozzle 4 is directed toward the sludge pile, and then control the external water pump to supply water to the water pipe 1, so that the water flows from the water pipe 1 to the connecting pipe 5, passes through the through holes on the first block 8 and the second block 9 in turn, and is then sprayed to the left through the nozzle 4, thereby gradually dispersing the sludge through the high-pressure water flow and diluting it into slurry, so as to facilitate the subsequent suction operation of the sludge.

[0027] When the sludge is to be dispersed, the second handle 3001 can be held to fix the sliding sleeve 3, and then the first handle 2001 can be pushed forward or backward, thereby driving the connecting tube 2 and the parts connected thereto to move, and the water pipe 1 can slide on the sliding sleeve 3 to achieve precise or large-area dispersion of the sludge. When it is necessary to disperse the sludge at different distances, the first handle 2001 can be twisted to rotate the connecting tube 2 on the water pipe 1, thereby driving the nozzle 4 to rotate through the connecting tube 2, and then driving the second block 9 to rotate through the nozzle 4, so that the flow channel formed between the through hole on the second block 9 and the through hole on the first block 8 is reduced, thereby achieving an increase in the water pressure sprayed by the nozzle 4, and thereby increasing the distance of the water flow sprayed by the nozzle 4, so that the sludge at a long distance can be dispersed, which is effectively convenient for manual operation without the need for users to move frequently.

[0028] In the process of impacting the sludge, when the sludge layer has a certain thickness, the sludge in the upper layer is dispersed and diluted into mud. Under the obstruction of the upper mud, the water flow has a poor effect on dispersing the sludge in the lower layer. If the nozzle 4 is directly inserted into the sludge for downward spraying, the water flow sprayed downward is difficult to make the sludge move in a large range in the horizontal direction, resulting in the sludge being repeatedly impacted in situ, and it is difficult to disperse and carry away the sludge. In the present invention, the nozzle 4 and its connected parts are manually driven to be inserted downward into the sludge. In the process of the nozzle 4 being inserted downward into the sludge, Figure 3As shown, under the blocking and squeezing of the squeezing plate 6001 by the silt, the sealing ring 6 is pushed upward, so that the sealing ring 6 releases the blockage of the water outlet 5001, so that the water flow can pass through the water outlet 5001 and the through groove 4001 in turn, and then spray out to the surroundings of the nozzle 4, so as to achieve the operation of dispersing the silt beside the nozzle 4, effectively increase its range of action, and then effectively enhance the effect of dispersing the lower layer of silt. When the squeezing plate 6001 is separated from the silt, under the impact of the water flow, the connecting frame 7 and the first stop block 8 can be pushed to move in the direction close to the second stop block 9, and then the sealing ring 6 is driven by the connecting frame 7 to move to re-block the water outlet 5001, so that the water flow is only sprayed out from the left opening of the nozzle 4, so as to continue the operation of dispersing the silt.

[0029] Furthermore, when there are many large stones in the silt, the stones block the nozzle 4, making it difficult to adjust the direction of the nozzle 4 when inserting it into the gap between the stones, so as to impact the silt in the gap between the stones, thereby resulting in poor effect of dispersing the silt in the gap between the stones. In the present invention, the nozzle 4 can be inserted into the gap between the stones, and the sealing ring 6 can be moved upward under the pressure of the stones, so that the water flow sprayed from the water outlet 5001 can be targetedly impacted on the silt in the gap between the stones, thereby effectively ensuring the effect of dispersing the silt.

[0030] When the silt is hard and needs to be impacted with a larger water pressure, since the reaction force generated by the nozzle 4 is also larger when it sprays a larger water pressure, it is difficult to hold the water pipe 1 manually to stabilize it, and it may even slip out of the hand. At this time, the support plate 102 can be placed against the ground. When the nozzle 4 sprays water to impact the silt, the water pipe 1 can be supported and supported by the support rod 101 and the support plate 102 to prevent the user from losing his hand due to excessive water pressure, effectively ensuring the safety of the user. The fixing rod 103 can be used to enhance the grip of the support plate 102 to effectively prevent the support plate 102 from slipping. At the same time, the foot can be placed on the upper side of the support plate 102 to further enhance the stability of the support plate 102.

[0031] Example 2 On the basis of Example 1, Figure 1-Figure 5 As shown, a suction pipe 201 is also included; the suction pipe 201 is fixedly connected to the abutting plate 102 , the suction pipe 201 is connected to an external mud pump through a pipeline, and the pipe mouth of the suction pipe 201 passes through the abutting plate 102 .

[0032] A through opening 10201 is formed on the abutting plate 102 ; the inner diameter of the through opening 10201 is larger than the outer diameter of the nozzle 4 .

[0033] A cleaning plate 301 is also included; the cleaning plate 301 is detachably plugged into the lower side of the abutment plate 102 , and all the fixing rods 103 penetrate the cleaning plate 301 .

[0034] Two pull rings are provided on the cleaning plate 301 to facilitate manual pulling thereof.

[0035] When the silt is dispersed by spraying water through the nozzle 4, the abutment plate 102 can be placed against the ground, and then the mud pump can be controlled to pump the dispersed silt through the suction pipe 201, so that the silt can be pumped away in time after being dispersed, avoiding the dispersed silt from continuing to accumulate in place and affecting the user's activities. When the silt is sucked through the suction pipe 201, other aquatic plants, garbage and other debris in the silt can be intercepted by the fixed rod 103, effectively preventing the debris from being sucked into the suction pipe 201 and causing the suction pipe 201 to be blocked.

[0036] Further, in order to prevent the dispersed silt and the ejected water from being continuously accumulated in the same place and unable to flow away quickly when the nozzle 4 is inserted into the silt for impacting, thereby affecting the impact effect on other silts, the following method can be used: Figure 4 and Figure 5 As shown, the support rod 101 is rotated to be parallel to the water pipe 1 by manually holding the second handle 3001, and then the first handle 2001 is pushed downward to drive the connecting tube 2 and the parts connected thereto to move downward, so that the nozzle 4 is inserted into the through opening 10201. Therefore, when the nozzle 4 is inserted into the silt to impact the silt, the dispersed silt can be promptly sucked away through the suction pipe 201 to prevent it from continuing to accumulate in place and blocking the water flow continued to be sprayed from the nozzle 4, thereby effectively ensuring the effect of the nozzle 4 on dispersing the silt. At the same time, the rebounding water flow and silt can be intercepted by the abutment plate 102 to prevent them from splashing onto the user, and the small stones below can be fixed by the fixing rod 103 to prevent the small stones from being washed away by the water flow or sucked into the suction pipe 201.

[0037] After using the present invention for a period of time, debris such as water plants and garbage may get stuck between the fixing rods 103, so the cleaning plate 301 can be pulled downward to scrape the fixing rods 103, so that the debris on the fixing rods 103 can be scraped away and cleaned by the cleaning plate 301 to ensure the normal use of the fixing rods 103.

[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
