Description

Technical Field

[0001] The present invention relates to drainage equipment, in particular to drainage equipment used in building construction and applied in the technical field of building construction. Background Art

[0002] When a construction site starts work, a foundation pit will be dug. Once it rains, water will accumulate in the foundation pit. If the water in the foundation pit is not dealt with quickly, construction will be delayed, and a lot of manpower and time will be wasted. At this time, the commonly used method on the construction site is to use a drainage pump to drain the foundation pit. However, the situation on the construction site is complicated, and the accumulated water often contains sand, soil, stones, wood chips, etc., which can easily cause the drainage pump to be blocked, making the drainage pump unable to work normally.

[0003] The specification of Chinese invention patent CN202322207166.8 discloses a new type of water pump, which includes a pump casing, a water outlet is provided on the top of the pump casing, a water inlet is provided on the surface of the pump casing, a groove is provided on the inner wall of the water inlet, and a filter screen is fixedly connected to the inner wall of the groove, an interface clamp is movably connected to the surface of the water inlet, threaded holes are provided on the opposite surfaces of the interface clamp, and the internal threads of the two threaded holes are connected to the same threaded column; its beneficial effect is that the impurities in the water can be intercepted at the water inlet through the filter screen when the machine is working, and more water can be discharged by the high-speed rotation of the double impeller on the pump shaft, but when faced with poor water quality such as in the construction site environment, this new type of water pump may have mud and sand attached to the filter screen, causing blockage.

[0004] In order to solve the problem that impurities in the water affect the operation of the drainage pump when the water quality is poor, such as the mud and sand in the accumulated water adhering to the filter net causing the drainage pump to be blocked, making the drainage pump unable to work normally, in order to solve the above problems we propose a drainage equipment for construction.

[0010] The signal processing system comprises a flushing processing module and a switching processing module. The switching processing module is electrically connected to the electromagnetic flowmeter, the liquid level sensor and the rotating motor respectively, and the flushing processing module is electrically connected to the water inlet device.

[0011] The above-mentioned drainage equipment for construction can be operated in poor water quality at the construction site, and it is not easy for sediment to adhere to the filter net and cause a decrease in drainage volume.

[0012] As a further improvement of the present application, the filter device is provided with a plurality of small-pore filter screens distributed along its circumference, and the positions of the small-pore filter screens correspond to the water inlet and the sewage outlet.

[0013] As a further improvement of the present application, a sludge concentration sensor A is provided at the top of the sewage outlet, and the sludge concentration sensor A is electrically connected to the flushing treatment module.

[0014] As a further improvement of the present application, the flushing device includes an upper rotating shaft, which is fixed at the bottom end of the large impeller. A one-way tooth is provided at the bottom end of the upper rotating shaft. The one-way tooth at the bottom end of the upper rotating shaft matches the one-way tooth at the top end of the lower rotating shaft. The lower rotating shaft is fixed at the upper end of the small impeller shaft.

[0015] As another improvement of the present application, a sliding hole is provided at the lower end of the lower rotating shaft, a fixing hole is provided laterally at the upper end of the impeller rotating shaft, a fixing rod is provided in the fixing hole of the impeller rotating shaft and is plugged into the sliding hole of the lower rotating shaft, and the lower end of the lower rotating shaft is made of magnetic material.

When the amount of silt attached to the small-pore filter is large, the switching processing module judges the signals transmitted by the electromagnetic flowmeter and the liquid level sensor, and controls the rotating motor to rotate the filter device, thereby switching the small-pore filter, and controlling the electromagnet to cut off power, so that the elastic member will support the upper rotating shaft to match and contact with the lower rotating shaft, so that the power of the motor drives the small impeller, thereby The small-pore filter is flushed by centrifugal action. At this time, the flushing treatment module monitors the flushing water through the sludge concentration sensor A. When the sludge concentration of the flushing water meets the requirements, the flushing treatment module will control the electromagnet to energize, disconnect the upper rotating shaft from the lower rotating shaft, thereby stopping the flushing of the small-pore filter. The silt flushed is collected in the sludge storage box to avoid pollution of the water quality around the drainage pump and increase the workload. Through the above process, when the water pump is in the case of silt in the water, it can reduce the situation where silt will adhere to the filter net and cause a decrease in drainage volume, thereby reducing the frequency of manual cleaning.

Through the above structure, the motor 34 can drive the large impeller 21 to rotate rapidly, thereby generating centrifugal force on the water, so that the water in the water outlet device 2 will be discharged from the water outlet hole 23 under the action of the centrifugal force.

[0036] The signal processing system includes a flushing processing module and a switching processing module. The switching processing module is electrically connected to the electromagnetic flowmeter 24, the liquid level sensor 26 and the rotating motor 19 respectively. The flushing processing module is electrically connected to the water inlet device 1. The switching processing module can determine the blockage condition of the filter device 13 by judging the signals transmitted by the electromagnetic flowmeter 24 and the liquid level sensor 26, thereby judging whether the rotating motor 19 is needed to rotate the filter device 13; a plurality of small-pore filter screens 131 distributed along its circumference are provided in the filter device 13, and the small-pore filter screens 131 correspond to the positions of the water inlet hole 16 and the sewage outlet hole 17, so that after the filter device 13 is switched once, the blocked small-pore filter screen 131 is directly opposite to the sewage outlet hole 17, which is convenient for cleaning and use of the small-pore filter screen 131; a sludge concentration sensor A171 is provided at the top of the sewage outlet hole 17, and the sludge concentration sensor A171 is electrically connected to the flushing processing module.

[0037] See also Figure 5 and Figure 6The flushing device 15 comprises an upper rotating shaft 151, which is fixed at the bottom end of the large impeller 21, and a one-way tooth is arranged at the bottom end of the upper rotating shaft 151, and the one-way tooth at the bottom end of the upper rotating shaft 151 matches the one-way tooth at the top end of the lower rotating shaft 152, and the lower rotating shaft 152 is fixed to the upper end of the small impeller rotating shaft 155; a sliding hole is provided at the lower end of the lower rotating shaft 152, and a fixing hole is transversely provided at the upper end of the small impeller rotating shaft 155, and a fixing rod 157 which is plugged into the sliding hole of the lower rotating shaft 152 is provided in the fixing hole of the small impeller rotating shaft 155, and the lower end of the lower rotating shaft 152 is made of magnetic material; an elastic member 153 is fixed between the lower rotating shaft 152 and the small impeller rotating shaft 155, and the bottom of the elastic member 153 is installed There is an electromagnet 154, and the elastic member 153 and the electromagnet 154 are all fixed at the bottom end of the middle hole opened in the impeller shaft 155.

When the electromagnet 154 is powered on, the electromagnet 154 is magnetic and attracts the lower rotating shaft 152 with magnetic material to move, so that the upper rotating shaft 151 is disconnected from the lower rotating shaft 152, so that the impeller 156 loses power and no longer rotates.

[0038] See also Figure 1 and Figure 7 The top of the water-blocking groove 25 is fixed on the water outlet housing 22, which will not hinder the rotation of the filter device 13 and keep the water-blocking groove 25 relatively still. A small-pore filter screen 131 is arranged on the periphery of the dirt storage box 12, so that the cleaned mud and sand on the small-pore filter screen 131 can be collected without affecting the water quality around the water pump. A movable handle 33 is fixed on the top of the motor housing 32 to facilitate the movement of the drainage equipment.

[0039] In summary, the working condition of this embodiment is that the bottom of the accumulated water is relatively clean. At this time, the motor 34 of the drainage pump drives the large impeller 21 to drain water, and the large-pore filter A18 of the water inlet 16 filters large particles of impurities, and small particles of silt are filtered through the small-pore filter 131. When the amount of silt attached to the small-pore filter 131 is large, the switching processing module judges the signals transmitted by the electromagnetic flowmeter 24 and the liquid level sensor 26, and controls the rotating motor 19 to rotate the filter device 13, thereby switching the small-pore filter 131 and controlling the electromagnet 154 to cut off the power, so that the elastic member 153 will support the upper rotating shaft 151 to match and contact with the lower rotating shaft 152, so that the power of the motor 34 To drive the small impeller 156, so that the small hole filter 131 is flushed through the centrifugal action of the small impeller 156. At this time, the flushing treatment module monitors the flushing water through the sludge concentration sensor A171. When the sludge concentration of the flushing water meets the requirements, the flushing treatment module will control the electromagnet 154 to energize, so that the upper rotating shaft 151 is disconnected from the lower rotating shaft 152, thereby stopping the flushing of the small hole filter 131, and the mud and sand flushed are collected in the dirt storage box 12, avoiding pollution of the water quality around the drainage pump and increasing the workload; through the above process, when the water pump is in the mud and sand in the water, it can reduce the situation where the mud and sand adhere to the filter net and cause the discharge volume to drop, and reduce the frequency of manual cleaning.

[0040] The second implementation method:

[0041] See also Figure 8-Figure 10 , which is different from the first embodiment, the water inlet 16 can be installed with the water inlet moving device 4 after removing the large-pore filter A18, and the water inlet moving device 4 includes a float 41.

A moving rod 42 is fixed at the lower end of the float 41, and a moving motor 43 is fixed at the lower end of the moving rod 42. A telescopic tube 44 is provided on one side of the moving rod 42. The purpose of the above structure is to realize that the pipe mouth of the telescopic tube 44 moves up and down in the vertical direction of the moving rod 42 A large-pore filter B46 is fixed to the water inlet of the telescopic tube 44 for filtering large debris such as stones and wood blocks. A sludge concentration sensor B45 is fixed to the upper end of the telescopic tube 44. The signal processing system also includes a mobile processing module, which is electrically connected to the sludge concentration sensor B45 and the mobile motor 43 respectively. The mobile processing module monitors the water quality through the sludge concentration sensor B45. When the water quality is poor, the position of the telescopic tube 44 and the sludge concentration sensor B45 is changed by the mobile motor 43 to find a cleaner water level.

[0042] In summary, the working conditions of this embodiment are that the water quality at the bottom of the accumulated water is poor. At this time, the float 41 of the water inlet moving device 4 will keep it in a state perpendicular to the horizontal plane. At this time, the mobile processing module will monitor the water quality through the sludge concentration sensor B45. When the water quality of this layer is poor, the mobile processing module will control the moving motor 43 to move the telescopic tube 44 and the sludge concentration sensor B45 up and down in the vertical direction of the moving rod 42, and find a relatively clean liquid surface through the monitoring data of the sludge concentration sensor B45, thereby reducing the working pressure of the drainage pump water inlet device 1 and improving the working efficiency of the drainage pump.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
