This patent discloses a mechanical sewage sampler, wherein a vent hole and a sampling valve are provided on the upper part of the trigger chamber, one end of the first piston rod is connected to a trigger needle, one end of the trigger needle is located outside the housing, the second end of the first piston rod is connected to the first end of the first spring, the second end of the first spring is connected to the first end of the first piston, the first end of the second piston rod is connected to the first piston, the second end of the second piston rod is arranged outside the housing, the second end of the second piston rod is covered with a second spring, one end of the second spring is connected to the second piston rod, the other end of the second spring is connected to the housing, and one end of the second piston provided in the pressure chamber is respectively connected to one end of the pipette and the sampling port;

[0004] There are a lot of impurities such as garbage in sewage. Garbage usually floats on the surface of sewage, and then the impurities will form a certain hard layer on the water surface. Therefore, it is impossible to effectively extend into the sewage during the sampling process. Moreover, during the sampling process, garbage will also block the sampling port, resulting in low sampling efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a mechanical sewage sampler to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a mechanical sewage sampler, including a starting device, the outer wall of the starting device is fixedly connected to a mounting plate, the mounting plate is installed on a required transport device or transport vehicle, the transport device or transport vehicle drives the suction pipe to slowly descend toward the sewage, the starting device is powered on to drive the spiral rod to rotate, during the rotation of the spiral rod, the sewage can be driven to rise into the suction pipe, and the sewage can finally be taken out from the temporary storage pipe, the bottom of the starting device is fixedly connected to the suction pipe, the bottom of the starting device is located inside the suction pipe and is rotatably connected to the spiral rod, and the outer wall of the suction pipe is fixedly connected to a pressing mechanism;

[0007] The pressing mechanism comprises:

[0008] A connecting rod, the connecting rod being fixedly connected to the outer wall of the suction pipe;

[0009] The electric slider, the outer wall of the connecting rod is fixedly connected to the outer wall of the electric slider, the electric slider drives the slide rail to move up and down continuously, so that the second clapping plate and the first clapping plate are continuously squeezed onto the water surface, and the water surface fluctuates toward the outer circle to guide the garbage away from the position of the suction pipe, which plays the effect of guiding the garbage away from the suction pipe, ensuring the normal sampling of the suction pipe, and when the slide rail moves up and down, it will drive the guide plate to swing and hit the slide rail, thereby driving the second clapping plate and the first clapping plate to vibrate, so that the garbage adhered to the second clapping plate and the first clapping plate falls off, ensuring that when the second clapping plate and the first clapping plate do not squeeze the garbage, the vibration generated by the swing of the guide plate will accelerate the garbage adhered to the second clapping plate and the first clapping plate to fall off;

[0010] The slide rail, the electric slider is slidably connected to the inside of the slide rail, before the suction pipe is extended into the sewage, the electric slider is powered on and started. Since the electric slider is fixed, it will drive the slide rail to move up and down when it is started, and will drive the second clap plate to descend when the slide rail descends. The second clap plate descends to the bottom of the suction pipe, and then the first clap plate and the second clap plate are squeezed onto the garbage above the sewage. When the first clap plate descends, it passes through the expulsion plate, which will squeeze the expulsion plate and deform it, and then the first clap plate will pass normally. A gap is opened on the first clap plate at the bottom, so it can pass the motor normally, and then the hard layer on the sewage surface is broken under the squeezing of the first clap plate and the second clap plate.

[0011] Preferably, a second clapping plate is fixedly connected to one side of the slide rail, and the number of the second clapping plates is two.

[0012] Preferably, a first clapping plate is fixedly connected to the other side of the slide rail, and the first clapping plate and the second clapping plate squeeze onto the garbage above the sewage to ensure that the garbage falls into the sewage. By utilizing the flow effect of water flow, the garbage can be effectively guided away in combination with the rotation of the expelling plate, thereby preventing the garbage from affecting the sampling efficiency of the suction tube. The first clapping plate and the second clapping plate squeeze the hard layer on the surface of the sewage to break up, thereby ensuring that when the suction tube descends into the sewage, the hard layer does not cause blockage at the bottom of the suction tube, thereby ensuring the normal sampling efficiency of the suction tube. Moreover, the descent of the second clapping plate and the first clapping plate will also cause the garbage on the water surface to fall into the water, allowing the suction tube to descend normally. The first descent of the second clapping plate and the first clapping plate prevents the suction tube from being directly squeezed onto the garbage, and the number of the first clapping plates is two.

[0013] Preferably, the outer wall of the slide rail is fixedly connected to the first bearing, and the outer wall of the first bearing is rotatably connected to the guide plate. The descent of the second clap plate and the first clap plate will also cause the garbage on the water surface to fall into the water, allowing the suction tube to descend normally. Then the electric slider drives the slide rail to move up and down continuously, causing the second clap plate and the first clap plate to be continuously squeezed onto the water surface. The water surface fluctuates toward the outer circle to guide the garbage away from the position of the suction tube. Under normal circumstances, the guide plate is in a hanging state, and then the slide rail will drive the guide plate to swing and hit the slide rail when it moves up and down, thereby driving the second clap plate and the first clap plate to vibrate, causing the garbage adhering to the second clap plate and the first clap plate to fall off.

[0014] Preferably, a temporary storage tube is fixedly connected to the outer wall of the suction tube, and a first bracket is fixedly connected between the temporary storage tube and the suction tube.

[0015] Preferably, an expulsion mechanism is fixedly connected to the outer wall of the suction pipe, and the expulsion mechanism includes a second bracket, and the second bracket is fixedly connected to the outer wall of the suction pipe. When the suction pipe descends into the sewage, the slide rail drives the second clapping plate and the first clapping plate to rise, and then during the process of the suction pipe sucking the sewage, the motor is powered on and started, and the motor drives the gear to rotate. The gear engages with the gear ring to drive the rotating tube to rotate. The rotating tube is rotatably connected to the suction pipe through the second bearing, and then the rotating tube drives the expulsion plate to rotate during the rotation process. The rotation of the expulsion plate guides the garbage near the suction pipe away and prevents the garbage from approaching the suction pipe.

[0016] Preferably, the outer wall of the second bracket is fixedly connected to a motor, and the bottom of the motor is rotatably connected to a gear. The gear meshes with the gear ring to drive the rotating tube to rotate. The rotating tube is rotatably connected to the suction tube through a second bearing. Then, the rotating tube drives the expulsion plate to rotate during the rotation. The rotation of the expulsion plate guides the garbage near the suction tube away and prevents the garbage from approaching the suction tube, thereby ensuring the expulsion of the garbage during the sampling process of the suction tube and improving the sampling efficiency of the suction tube. The outer wall of the suction tube is rotatably connected to the second bearing, and the outer wall of the second bearing is fixedly connected to the rotating tube.

[0017] Preferably, a gear ring is fixedly connected to the outer wall of the rotating tube, and the gear ring is meshingly connected to the gear. An expulsion plate is fixedly connected to the outer wall of the rotating tube, and the expulsion plate is made of rubber material.

[0018] The present invention provides a mechanical sewage sampler, which has the following beneficial effects:

[0019] 1. The mechanical sewage sampler squeezes the garbage on the sewage through the first and second clap plates, ensuring that the garbage falls into the sewage. By utilizing the flow effect of water flow, the garbage can be effectively guided away in combination with the rotation of the expelling plate, avoiding the garbage from affecting the sampling efficiency of the suction tube. The first and second clap plates squeeze the hard layer on the sewage surface to break it up, ensuring that when the suction tube is lowered into the sewage, the hard layer does not cause blockage at the bottom of the suction tube, ensuring the normal sampling efficiency of the suction tube. Moreover, the descent of the second and first clap plates will also cause the garbage on the water surface to fall into the water, allowing the suction tube to descend normally. The first descent of the second and first clap plates avoids the suction tube being directly squeezed onto the garbage.

[0020] 2. The mechanical sewage sampler drives the slide rail to move up and down continuously through the electric slider, so that the second clap plate and the first clap plate are continuously squeezed onto the water surface. The water surface fluctuates toward the outer circle to guide the garbage away from the position of the suction tube, thereby guiding the garbage away from the suction tube and ensuring the normal sampling of the suction tube. When the slide rail moves up and down, it will drive the guide plate to swing and hit the slide rail, thereby driving the second clap plate and the first clap plate to vibrate, causing the garbage adhered to the second clap plate and the first clap plate to fall off, ensuring that when the second clap plate and the first clap plate do not squeeze the garbage, the vibration generated by the swinging of the guide plate will accelerate the falling of the garbage adhered to the second clap plate and the first clap plate.

[0021] 3. The mechanical sewage sampler drives the rotating tube to rotate by meshing the gear and the gear ring. The rotating tube is rotatably connected to the suction tube through the second bearing. Then, the rotating tube drives the expulsion plate to rotate during the rotation. The rotation of the expulsion plate guides the garbage near the suction tube away and prevents the garbage from approaching the suction tube, thereby ensuring the expulsion of garbage during the sampling process of the suction tube and improving the sampling efficiency of the suction tube.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Embodiment 1

[0034] See also Figure 1-7 The present invention provides a technical solution: a mechanical sewage sampler, comprising a starting device 2, the outer wall of the starting device 2 is fixedly connected to a mounting plate 1, the bottom of the starting device 2 is fixedly connected to a suction pipe 3, the bottom of the starting device 2 is rotatably connected to a spiral rod 4 located inside the suction pipe 3, and the outer wall of the suction pipe 3 is fixedly connected to a pressing mechanism 7;

[0035] The pressing mechanism 7 comprises:

[0036] A connecting rod 71, the connecting rod 71 is fixedly connected to the outer wall of the suction pipe 3;

[0037] The outer wall of the electric slider 72 and the connecting rod 71 are fixedly connected to the outer wall of the electric slider 72. The electric slider 72 drives the slide rail 74 to move up and down continuously, so that the second clapping plate 73 and the first clapping plate 75 are continuously squeezed onto the water surface. The water surface fluctuates toward the outer circle to guide the garbage away from the position of the suction pipe 3, thereby guiding the garbage away from the suction pipe 3 and ensuring the normal sampling of the suction pipe 3. When the slide rail 74 moves up and down, it will drive the guide plate 76 to swing and hit the slide rail 74, thereby driving the second clapping plate 73 and the first clapping plate 75 to vibrate, so that the garbage adhered to the second clapping plate 73 and the first clapping plate 75 will fall off, ensuring that when the second clapping plate 73 and the first clapping plate 75 do not squeeze the garbage, the vibration generated by the swing of the guide plate 76 will accelerate the garbage adhered to the second clapping plate 73 and the first clapping plate 75 to fall off;

[0038] The slide rail 74 and the electric slider 72 are slidably connected inside the slide rail 74 .

[0039] A second clapping plate 73 is fixedly connected to one side of the slide rail 74 , and the number of the second clapping plates 73 is two.

[0040] The other side of the slide rail 74 is fixedly connected with a first clapping plate 75, which squeezes the garbage on the sewage and the second clapping plate 73 to ensure that the garbage falls into the sewage. By utilizing the effect of water flow, the garbage can be effectively guided away by the rotation of the expelling plate 86, thereby preventing the garbage from affecting the sampling efficiency of the suction tube 3. The first clapping plate 75 and the second clapping plate 73 squeeze the hard layer on the sewage surface to break up, thereby ensuring that when the suction tube 3 is lowered into the sewage, the hard layer is prevented from causing blockage at the bottom of the suction tube 3, thereby ensuring the normal sampling efficiency of the suction tube 3. Moreover, the descent of the second clapping plate 73 and the first clapping plate 75 will also cause the garbage on the water surface to fall into the water, thereby allowing the suction tube 3 to descend normally. The first descent of the second clapping plate 73 and the first clapping plate 75 prevents the suction tube 3 from being directly squeezed onto the garbage, and there are two first clapping plates 75.

The starting device 2 is powered on to drive the spiral rod 4 to rotate. During the rotation of the spiral rod 4, the sewage can be driven to rise into the suction pipe 3, and the sewage can finally be taken out from the temporary storage tube 5. Before the suction pipe 3 extends into the sewage, the electric slider 72 is powered on and started. Since the electric slider 72 is fixed, the electric slider 72 will drive the slide rail 74 to move up and down when it is started. When the slide rail 74 descends, it will drive the second clapping plate 73 to descend. The second clapping plate 73 descends to the bottom position of the suction pipe 3, and then the first clapping plate 75 and the second clapping plate 73 are squeezed onto the garbage above the sewage. When the first clapping plate 75 descends, it passes through the expulsion plate 86, which will squeeze the expulsion plate 86 and deform, and then make the first clapping plate 75 pass normally. , a gap is opened on the first clapping plate 75 at the bottom, so it can pass through the motor 84 normally, and then the hard layer on the sewage surface is broken under the squeezing of the first clapping plate 75 and the second clapping plate 73, and the descent of the second clapping plate 73 and the first clapping plate 75 will also cause the garbage on the water surface to fall into the water, so that the suction pipe 3 can descend normally, and then the electric slider 72 drives the slide rail 74 to move up and down continuously, so that the second clapping plate 73 and the first clapping plate 75 are continuously squeezed onto the water surface, and the water surface fluctuates toward the outer circle to guide the garbage away from the position of the suction pipe 3. Under normal circumstances, the guide plate 76 is in a hanging state, and then the slide rail 74 will drive the guide plate 76 to swing and hit the slide rail 74 when it moves up and down, thereby driving the second clapping plate 73 and the first clapping plate 75 to vibrate, so that the garbage adhering to the second clapping plate 73 and the first clapping plate 75 falls off.
