In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a pump station provided by the present invention; fig. 2 is a top view of a submersible pump in the pump station of fig. 1.

The utility model provides a pump station structure is shown in figure 1, including casing 1 and immersible pump 2. Wherein, the shell 1 can be made of stainless steel or glass fiber reinforced plastics and other materials, and the submersible pump 2 is positioned in the shell 1. The lateral wall of casing 1 one side is equipped with inlet tube 13, and the end of inlet tube 13 is equipped with interception graticule mesh 5. Sewage enters the shell 1 along the water inlet pipe 13, and the interception grid 5 can intercept larger suspended matters of particles in the sewage outside the shell 1. Optionally, the interception grid 5 has tapered holes penetrating along the thickness direction, so the interception effect of the interception grid 5 is better and is not easy to block. The lateral wall of one side that casing 1 and inlet tube 13 are relative is equipped with the apopore, outlet pipe 11 and apopore sealing connection, and the export of immersible pump 2 links to each other with outlet pipe 11. When the sewage in the housing 1 reaches a certain level, the submersible pump 2 is started and delivers the sewage through the water outlet pipe 11. Optionally, a check valve 14 and a gate valve 15 are arranged in the water outlet pipe 11, and the check valve 14 can prevent sewage from flowing back into the shell 1. The gate valve 15 is provided with a strip-shaped handle, and the top of the shell 1 is provided with an operation hole. The operating personnel accessible specialized tool rotates the bar handle from the handle hole, and then need not to get into and can accomplish the switch of gate valve 15 in the casing 1.

Optionally, the pump station further comprises a controller and a level switch 10. The submersible pump 2 and the liquid level switch 10 are both connected with the controller, and the liquid level switch 10 is used for detecting a current liquid level signal and feeding back the current liquid level signal to the controller. When the sewage reaches the preset liquid level, the controller controls the submersible pump 2 to start. In this application, immersible pump 2 self has the cooling jacket, therefore it can avoid the water pump to do the commentaries on classics, burns out the motor, and then makes immersible pump 2's cavitation surplus improve. Promptly, immersible pump 2 can start when the sewage degree of depth is lower, has reduced the required degree of depth of casing 1, has increased the regulation volume that the water pump promoted, and then has reduced the cost of pump station. Wherein, the controller can be specifically a PLC controller or an industrial personal computer and the like.

In addition, a temperature sensor for water temperature, an ammeter and a voltmeter for detecting the 2 nd submerged pump can be arranged in the pump station. Liquid level switch, temperature sensor, ampere meter and voltmeter all link to each other with the controller, and the controller can upload to remote control platform, operating personnel accessible remote control platform control pump station's operating condition with the electric current, the voltage of immersible pump 2 and the water level of sewage in the casing, temperature.

Optionally, the top of the casing 1 is provided with an access hole penetrating along the thickness direction, a ladder 6 is arranged below the access hole, and an operator can enter the casing 1 through the access hole when necessary. The manhole is sealed through well lid 7, prevents that other sewage from getting into in the casing 1. In addition, the periphery of the well lid 7 is provided with a safety grating 8, so that the water quality in the shell 1 can be observed conveniently when the equipment runs.

The equipment runs for a long time, and more suspended matters can be accumulated in the interception grid 5, so that the resistance is increased, and the interception grid 5 needs to be cleaned regularly. In order to facilitate cleaning of the interception grid 5, a lifting chain and a lifting guide rail are arranged in the housing 1. Specifically, interception graticule mesh 5 is installed on promoting the guide rail, and the lifting chain links to each other with interception graticule mesh 5. When needs clearance interception graticule mesh 5, will intercept graticule mesh 5 and demolish interception graticule mesh 5 to hoist through the lifting chain, make it rise to casing 1 top along the lifting guide.

Further, the pump station also includes a flush tube 16. As shown in fig. 1, the flushing pipe 16 is connected at one end to the water outlet pipe 11 and at the other end to the upper part of the interception grid 5. The water at the outlet of the submersible pump 2 flows under pressure along the flushing pipe 16 into the interception grid 5 and flushes the interception grid 5 with water pressure. Although washing interception graticule mesh 5 can't be with its clean up completely, the interception graticule mesh 5 pressure drop after washing reduces, can prolong the clearance cycle of interception graticule mesh 5.

Optionally, immersible pump 2 also breaks down for long-term use, and for convenient lift immersible pump 2, the casing 1 inboard still is equipped with water pump guide rail 4. Before maintenance, the operator can lift the submersible pump 2 along the pump guide 4. In addition, in order to conveniently disassemble and assemble the submersible pump 2, a self-coupling base 3 is arranged between an outlet of the submersible pump 2 and the water outlet pipe 11. Immersible pump 2 can automatic locking through self coupling base 3 and outlet pipe 11, therefore when installing immersible pump 2, operating personnel only need simple operation can accomplish the installation in casing 1, has reduced operating personnel's work burden, has improved the installation effectiveness.

Alternatively, the housing 1 is typically buried underground in order to save space. For convenient transportation and installation, the outer side of the housing 1 is provided with a lifting lug 12. In addition, because the shell 1 is located outdoors, in order to avoid the sewage from freezing in winter, the outer side of the shell 1 is provided with a heat insulation layer. Specifically, the heat-insulating layer can be a three-layer structure coated on the shell 1, the outer layer of the heat-insulating layer is a thin-wall stainless steel shell, the inner layer of the heat-insulating layer is made of glass fiber reinforced plastics, and the middle layer of the heat-insulating layer is made of polyurethane or special polyethylene materials. The lowest end of the heat-insulating layer reaches the depth of the freezing line and extends upwards to the ground. The heat preservation can reduce the harm that low temperature brought to casing 1, has improved casing 1's structural strength to a certain extent simultaneously. Thereby greatly prolonging the service life of the pump station.

In addition, the interior of the shell 1 is in a relatively closed state for a long time, and in order to avoid overhigh pressure or overhigh concentration of harmful gas caused by gas aggregation in the shell 1, the top of the shell 1 is provided with a vent hole 9. The vent hole 9 communicates the inside and the outside of the casing 1, and plays a role in balancing the pressure inside and outside the casing 1. Of course, the user can also arrange a gas sensor at the periphery of the vent hole 9 according to the requirement, and the gas sensor is connected with the controller. When the gas sensor detects toxic and harmful gas, the controller reminds an operator to process through alarm devices such as an alarm lamp.

In this embodiment, the pump station will intercept graticule mesh 5, immersible pump 2 etc. and integrate in casing 1, reduced the space that the pump station occupies. And meanwhile, an integrated structure is adopted, so that the pump station can be directly buried underground in a hoisting mode, and the installation cost of the pump station is reduced. In addition, the pump station links to each other with the controller in this application, through the running situation of controller control immersible pump 2 and monitoring pump station, has realized the intelligent control of pump station, has reduced operating personnel and has monitored pump station work burden.
