All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The embodiment of the utility model discloses a pond dredging device. Referring to fig. 1 and 2, the pond dredging device comprises a fixed seat 1, a lifting seat 2 which is installed on the fixed seat 1 in a lifting manner, a water pump 3 which is installed on the lifting seat 2, and a sewage suction pipe 31 and a sewage discharge pipe 32 which are connected with the water pump 3; specifically, the lifting seat 2 can be arranged on the fixed seat 1 through lifting of an electric cylinder, and lifting on the fixed seat 1 can be realized through a gear rack lifting structure or a linear motor, and the water pump 3 is a sludge pump; wherein the drain pipe 32 is a hose, the sewage suction pipe 31 is a hard pipe, and may be a plastic hard pipe or a stainless steel pipe, so as to ensure that the bottom end of the sewage suction pipe 31 can be stably inserted into a pond sludge layer.

Still further, referring to fig. 1 and 2, the dirt absorbing cover 33 is installed at the bottom end of the dirt absorbing pipe 31, the detecting rod 41 parallel to the length direction of the dirt absorbing pipe 31 is arranged on the dirt absorbing cover 33 in a penetrating manner, the upper end of the detecting rod 41 penetrates through the lifting seat 2, the lower end of the detecting rod 41 extends into the dirt absorbing cover 33, the detecting head 42 is installed at the lower end of the detecting rod 41, when the detecting head 42 is suspended in water, the lower end of the detecting head 42 protrudes out of the bottom end of the dirt absorbing cover 33, and the lifting seat 2 is provided with a monitoring mechanism for judging whether the lower end of the detecting head 42 is flush with the lower end of the dirt absorbing cover 33 or moves upwards beyond the lower end of the dirt absorbing cover 33 through the position of the upper end of the detecting rod 41.

After setting up like this, when carrying out the desilting operation in the pond, firstly install fixing base 1 on the hull to drive the dirt suction pipe 31 through elevating socket 2 and move down, when dirt suction cover 33 did not contact with the silt layer of pond bottom, the detector head 42 was suspended in dirt suction cover 33 below under the effect of buoyancy, and was monitored by monitoring mechanism, when directly opening water pump 3 and dredging this moment, the fluid in the dirt suction pipe 31 was mostly pond water, seriously influenced the treatment effeciency of silt. The lifting seat 2 can be used for continuously downwards detecting the sewage suction pipe 31 until the monitoring mechanism monitors that the detection rod 41 moves upwards to the lower end of the detection head 42 to be moved upwards to the level or to cross the bottom end of the sewage suction cover 33, at the moment, the detection head 42 is pushed against the silt layer, the sewage suction cover 33 is embedded into the silt layer, and when the water pump 3 is started, the silt can be sucked to the maximum extent, so that the efficient dredging operation is realized.

In the specific arrangement, referring to fig. 1, the monitoring mechanism includes a monitoring head 43 fixedly connected to a side wall of the detecting rod 41 and a pressure sensor 44 mounted on the lifting seat 2, the pressure sensor 44 is arranged in a strip shape along the length direction of the detecting rod 41, the pressure sensor 44 is electrically connected with an alarm 45, and the alarm 45 can be a buzzer or an audible and visual alarm 45; and the monitoring head 43 abuts the pressure sensor 44 only when the detection lever 41 is moved up to the lower end of the detection head 42 flush with or up over the bottom end of the dirt pickup housing 33.

Thus, when the detecting head 42 is driven to move upwards by the reverse acting force of the silt layer, the monitoring head 43 on the detecting rod 41 is in conflict with the pressure sensor 44, the alarm 45 is controlled to be started or closed, and an operator can be visually warned.

In order to further improve the automation performance of the dredging device of the present utility model, the pressure sensor 44 may be connected to the water pump 3. Therefore, if the monitoring mechanism monitors that the bottom end of the dirt suction cover 33 is not embedded in the silt layer, the water pump 3 can be controlled to be turned off until the bottom end of the dirt suction cover 33 is embedded in the silt layer, and then the water pump 3 is controlled to be started, so that the automatic monitoring and starting and stopping of the water pump 3 in the dredging device can be realized.

Meanwhile, in order to improve the reaction sensitivity of the probe 42, the bottom end of the probe 42 may be provided with a convex hemispherical shape, more specifically, referring to fig. 2, the probe 42 may be provided with a spherical shape directly, that is, the contact area between the probe 42 and the silt layer may be increased by the lower spherical surface, so as to improve the reaction sensitivity; and the resistance to upward movement of the probe 42 can be reduced by the upper spherical surface.
