Description

Technical Field

[0001] The invention relates to the technical field of water treatment, and in particular to a siphon mud discharge vehicle. Background Art

[0002] Siphon mud discharge vehicle is a kind of equipment used to remove sediment, sludge and other underwater materials. It is commonly used in water treatment projects. It mainly uses a siphon tube to form negative pressure in the water and sucks and discharges the mud and sand through the siphon principle. This siphon mud discharge vehicle has strict requirements on the flocculent discharge of mud and water. It is easy to malfunction if it is too thick.

[0003] The sedimentation tanks of water plants usually use siphon sludge discharge vehicles to discharge sludge. This type of siphon sludge discharge vehicle needs to put the outlets of multiple sludge discharge pipes side by side to the bottom and push forward to siphon sludge discharge. Due to the small water level difference in the sedimentation tank, the sludge discharge effect is poor, and the floating sludge in the pool is easy to block the siphon sludge discharge pipe; on the other hand, the outlet of the sludge discharge pipe is usually flat, and the fallen leaves entering the bottom of the open-air sedimentation tank are easy to block the outlet of the sludge discharge pipe.

[0004] In addition, when workers fail to open the siphon for sludge discharge in time due to negligence or due to equipment damage, the floating sludge in the sedimentation tank will accumulate and harden, causing the sludge discharge vehicle to be unable to move forward and work normally, and production can only be stopped for manual cleaning.

[0005] Therefore, the existing siphon mud discharge vehicle has the disadvantages of low mud discharge efficiency, high power consumption, easy damage, and large waste of water resources. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a siphon mud discharge vehicle with a stronger mud discharge function.

[0007] The technical solution of the siphon mud discharge vehicle of the present invention is: a siphon mud discharge vehicle, including a truss, a suspension assembly, an electric push rod, a sewage pump, a siphon assembly, a first motor, a second motor, and a control system; under the drive of the first motor, the truss can move forward and backward longitudinally along the tracks on both sides of the pool through rollers; the upper end of the suspension assembly is installed on the transverse track of the truss through a hanging wheel and can move left and right under the drive of the second motor, the lower end of the suspension assembly is hinged to the upper end of the electric push rod, the lower end of the electric push rod is connected to the sewage pump, the power of the sewage pump is adjustable, and the water outlet of the sewage pump is connected to the siphon assembly; the electric push rod, the sewage pump, the first motor, and the second motor are all electrically connected to the control system.

[0008] In the above technical solution, the truss can move forward and backward longitudinally through rollers under the drive of the first motor, the upper end of the suspension assembly is installed on the transverse track of the truss through the suspension wheel and can move left and right under the drive of the second motor, the lower end of the suspension assembly is hinged with the upper end of the electric push rod, and the lower end of the electric push rod is installed with a sewage pump. Under the action of the electric push rod, the sewage pump can move up and down, so that the sewage pump can move in three dimensions: front and back, left and right, and up and down, and the sewage pump can also make a swing motion relative to the suspension assembly and the truss, so that the sewage pump can be moved to any part of the sedimentation tank to perform scanning mud discharge with left and right translation, and can adjust the height according to the thickness of the mud layer to perform layered mud discharge. When the truss drives the sewage pump to move forward and backward, if the sewage pump encounters an obstacle or a thicker and harder mud layer underwater, it can also swing back and forth to avoid damage to the vehicle.

[0009] Among them, through the cooperation of the sewage pump and the siphon component, three mud discharge modes can be formed: forced mud discharge, forced mud discharge combined with siphon mud discharge, and pure siphon mud discharge. In this way, different mud discharge modes can be switched according to different mud layer thicknesses, ensuring the mud discharge effect while saving power consumption.

[0010] In one embodiment, the lower end of the suspension assembly is connected to the upper end of the electric push rod through a pin and a bearing, and the installation direction of the pin is parallel to the transverse track of the truss. Furthermore, a damping sensor is provided on the suspension assembly, and the damping sensor is electrically connected to the control system. In this way, the electric push rod and the sewage pump can make a swinging motion relative to the suspension assembly. When the truss moves forward or backward, if the sewage pump installed at the lower end of the telescopic assembly hits an obstacle at the bottom of the pool or a thicker and harder mud layer, it can avoid it by passive swinging. The damping sensor can monitor the vertical state of the electric push rod. Once the electric push rod is detected to have a swing, a signal is sent to the control system. The control system turns off the first motor to stop the truss from moving, and controls the electric push rod to retract, raises the position of the sewage pump and returns it to a vertical state. At this time, the second motor drives the suspension assembly to move left and right, thereby driving the mud pump to perform a scanning mud discharge with a left and right translation.

[0011] In one embodiment, a connecting rod is provided at the upper part of the sewage pump, and the connecting rod and the lower end of the electric push rod are nested with each other and fixed by a latch, and a locking sleeve is also sleeved at the connection between the connecting rod and the electric push rod. With this structure, the sewage pump can be quickly assembled to or disassembled from the electric push rod, which is convenient for installation and maintenance.

[0012] In one embodiment, the connecting rod is a hollow tube, the lower end of the electric push rod is inserted into the connecting rod and fixed by a pin, the locking sleeve is provided with a stepped hole which is smaller at the top and larger at the bottom and can cover the connection between the connecting rod and the electric push rod, and the locking sleeve can slide up and down along the electric push rod.

[0013] In one embodiment, the siphon assembly includes a siphon pipe, a siphon breaking valve, a siphon water sealing bucket, a water valve, a swivel joint and a hose, wherein the hose is connected to the water outlet of the sewage pump. The siphon assembly can effectively form or break a siphon.

[0014] In one embodiment, the suspension wheel installed on the upper end of the suspension assembly is a gear, and the transverse track of the truss is a rack. The use of such a gear and rack structure can make the moving distance of the suspension assembly more accurate.

[0015] In one embodiment, a retractable underwater camera is also included, so that the thickness of the underwater mud layer can be directly observed.

[0016] In one embodiment, the sewage pump is an automatic stirring submersible sewage pump; the control system includes a PLC, a frequency converter and a touch screen.

[0017] The beneficial effects of the present invention are: 1) The mud discharge vehicle provided by the present invention can enable the sewage pump to move in three dimensions, front and back, left and right, and up and down, so that any part of the bottom of the water can be scanned and discharged by translation, and mud can be discharged for mud layers of different thicknesses on the bottom of the water; thus, the horizontal flow sedimentation tank can be operated continuously for a long time without stopping operation every year for manual dredging, which not only saves a large amount of flushing water required for cleaning the sedimentation tank, but also saves the labor cost of cleaning the accumulated mud; 2) Since the lower end of the suspension assembly is hinged to the upper end of the electric push rod, the sewage pump installed at the lower end of the electric push rod can swing relative to the suspension assembly and the truss. When the thickness of the mud at the bottom of the pool is uneven, the mud pump can avoid it by swinging, avoiding damage to the mud pump and unilateral blocking of the vehicle; 3) Since the power of the sewage pump is adjustable, the water outlet of the sewage pump is connected to the siphon assembly, so that the siphon assembly and the sewage pump can be combined to discharge mud, thereby improving the mud discharge effect and avoiding sludge blocking the siphon assembly.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] It should be noted in advance that, in the present invention, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] like Figure 1 , 2 A siphon mud discharge vehicle shown in the figure includes a truss 1, a suspension component 2, an electric push rod 3, a sewage pump 4, a siphon component, a first motor, a second motor, and a control system; the bottom of the truss 1 is provided with two rows of rollers on the left and right, and the upper part of the truss 1 is provided with a transverse track 5 and a transverse aisle. The truss 1 can move forward and backward longitudinally along the tracks on both sides of the pool through the rollers when driven by the first motor; the upper end of the suspension component 2 is installed on the transverse track 5 through a hanging wheel 6 and can move left and right when driven by the second motor. In order to make the moving distance of the suspension component 2 more accurate, the hanging wheel 6 in this embodiment is a gear, and the transverse track 5 is a rack, and the two form a gear rack transmission; the lower end of the suspension component 2 is hinged to the upper end of the electric push rod 3, and the lower end of the electric push rod 3 is hinged to the upper end of the electric push rod 3. The end is connected to the sewage pump 4; the sewage pump 4 is an automatic stirring submersible sewage pump 4 with adjustable power. The water outlet of the sewage pump 4 is connected to the siphon assembly. The siphon assembly includes a siphon tube 7, a siphon breaking valve 8, a siphon water seal bucket 9, a water valve 10, a rotary joint 11 and a hose 12. The hose 12 is connected to the water outlet of the sewage pump 4; the electric push rod 3, the sewage pump 4, the first motor and the second motor are all electrically connected to the control system, and the control system includes a PLC, a frequency converter and a touch screen; three mud discharge modes can be formed by cooperating with the sewage pump 4 and the siphon assembly: forced mud discharge, forced mud discharge combined with siphon mud discharge, and pure siphon mud discharge. In this way, different mud discharge modes can be switched according to different mud layer thicknesses, saving power consumption while ensuring the mud discharge effect.

[0022] like Figure 1 , 2As shown, in this embodiment, the lower end of the suspension assembly 2 is connected to the upper end of the electric push rod 3 through a pin and a bearing, and the installation direction of the pin is parallel to the transverse track 5 of the truss 1. The suspension assembly 2 is provided with a damping sensor 16, which is also electrically connected to the control system. In this way, the electric push rod 3 and the sewage pump 4 can make a swing motion relative to the suspension assembly 2. When the truss 1 moves forward or backward, if the sewage pump 4 installed at the lower end of the telescopic assembly hits an obstacle at the bottom of the pool or a thicker and harder mud layer, it can be avoided by passive swinging. The damping sensor 16 can monitor the vertical state of the electric push rod 3. Once the electric push rod 3 is detected to have a swing, a signal is sent to the control system, and the control system turns off the first motor to stop the truss 1 from moving, and controls the electric push rod 3 to shrink, raises the position of the sewage pump 4 and returns it to a vertical state. At this time, the second motor drives the suspension assembly 2 to move left and right, thereby driving the mud pump 4 to perform a scanning mud discharge with a left and right translation.

[0023] like Figure 1 , 3 As shown, a connecting rod 13 is provided on the upper part of the sewage pump 4. The connecting rod 13 and the lower end of the electric push rod 3 are nested with each other and fixed by a latch 14. A locking sleeve 15 is also sleeved at the connection between the connecting rod 13 and the electric push rod 3. Specifically, the connecting rod 13 can be set as a hollow tube, and the lower end of the electric push rod 3 is inserted into the connecting rod 13. The corresponding parts of the two are set in radial through holes. A plug 14 is inserted into the radial through holes of the two to fix the two. In order to prevent the plug 14 from coming out, a locking sleeve 15 that can slide up and down is provided on the electric push rod 3. The locking sleeve 15 is provided with a stepped hole that is small at the top and large at the bottom. When the locking sleeve 15 is downwardly sleeved on the connection between the connecting rod 13 and the electric push rod 3, the step surface of the stepped hole of the locking sleeve 15 just abuts against the upper end surface of the connecting rod 13, thereby limiting the locking sleeve 15. When disassembling, just move the locking sleeve 15 upward by hand, then pull out the plug 14, and then separate the connecting rod 13 from the electric push rod 3. With this structure, the sewage pump 4 can be quickly assembled on the electric push rod 3 or disassembled from the electric push rod 3, which is convenient for maintenance and repair of the sewage pump 4.

[0024] Figure 1 The water tank shown is a sedimentation tank of a waterworks, which is more than 100 meters long. The mud discharge vehicle of the embodiment spans across two sedimentation tanks, with a span of 10 meters. The mud discharge vehicle is provided with two suspension components 2, two electric push rods 3, and two sewage pumps 4 corresponding to each sedimentation tank. In order to directly observe the thickness of the underwater mud layer, a retractable underwater camera 17 can also be installed on the sewage pump 4. In order to facilitate the removal or installation of the sewage pump 4 on the electric push rod 3, the transverse track 5 of the truss 1 is deliberately set above the transverse aisle in this embodiment, so that it is convenient for maintenance personnel to stand on the transverse aisle for operation.

[0025] During operation, the siphon breaking valve 8 is closed, and the sewage pump 4 is turned on to allow the siphon component to establish a siphon. After the siphon is formed, the forced sludge discharge, the combined forced discharge and siphon discharge, or the pure siphon discharge is determined according to the thickness of the siltation at the bottom of the pool. Generally speaking, there are more opportunities and scenarios for using the combined forced discharge and siphon discharge, and the advantages are more obvious, because at this time the sewage pump 4 can be operated at low power to stir the sludge, stirring and siphoning at the same time, and then, through the forward and backward movement of the truss 1, the left and right movement of the suspension component 2, and the extension and retraction of the electric push rod 3, the sewage pump 4 can realize the movement in three dimensions: forward and backward, left and right, and up and down, and the sewage pump 4 can also make a swing motion relative to the suspension component 2 and the truss 1. Most of them In this case, the first motor drives the truss 1 to pause every time it moves forward along the length direction of the sedimentation tank, waiting for the second motor to drive the suspension assembly 2 to complete continuous left and right movement. Only when it reaches the front end of the gap at the water outlet of the horizontal flow sedimentation tank sump, the second motor drives the suspension assembly 2 to pause every time it moves forward a certain distance, waiting for the first motor to drive the truss 1 to complete continuous forward and backward movement. In this way, the sewage pump 4 can be moved to any part of the sedimentation tank to perform scanning mud discharge by left and right translation or forward and backward translation, and the height can be adjusted according to the thickness of the mud layer. When the truss 1 drives the sewage pump 4 to move forward and backward, if the sewage pump 4 encounters an obstacle or a thicker and harder mud layer underwater, it can also swing back and forth, thereby avoiding damage to the vehicle.

[0026] The mud-discharging vehicle provided by this embodiment can achieve the following beneficial effects: 1) Since the mud discharge vehicle provided in this embodiment can enable the sewage pump 4 to move in three dimensions, front and back, left and right, and up and down, it can perform scanning mud discharge on any part of the bottom of the water by moving forward and backward or left and right, and can discharge mud for mud layers of different thicknesses on the bottom of the water; thus, the horizontal flow sedimentation tank can be operated continuously for a long time without stopping the operation every year for manual dredging, which not only saves a large amount of flushing water required for cleaning the sedimentation tank, but also saves the labor cost of cleaning the accumulated mud; 2) Since the lower end of the suspension assembly 2 is hinged to the upper end of the electric push rod 3, the sewage pump 4 installed at the lower end of the electric push rod 3 can swing relative to the suspension assembly 2 and the truss 1. When the thickness of the mud at the bottom of the pool is uneven, the mud pump can avoid it by swinging, avoiding damage to the mud pump and unilateral blocking of the vehicle; 3) Since the power of the sewage pump 4 is adjustable, the water outlet of the sewage pump 4 is connected to the siphon assembly, so that the siphon assembly and the sewage pump 4 can be combined to discharge mud, thereby improving the mud discharge effect and preventing the siphon assembly from being blocked by mud.

[0027] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and the above-mentioned embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
