Description

Hidden danger-free pump station

Technical Field

The invention relates to the field of drainage, in particular to a hidden danger-free pump station.

Background

Most of water pumps of the existing rain sewage pumping stations adopt submersible sewage pumps, and the submersible sewage pumps need to be started at a high water level and stopped at a low water level when working. Simultaneously, current pump station, in order to further prevent that filth etc. of bottom of the pool from blockking up, still pumped the entrance and set up the filter screen to sewage can be discharged by the sewage pump after filtering via the filter screen. This kind of pump station, in the use at ordinary times, need not initiatively decontaminate, generally all be after the pump station blocks up, just carry out the desilting, overhaul to the pump station, the concrete process of desilting is: firstly, the submersible sewage pump is integrally lifted to the ground, then dredging personnel descend to the bottom of the tank, and sludge, garbage and the like precipitated at the bottom of the tank are cleaned. The pump station has the following problems in the use process:

1. because the submersible sewage pump has a shutdown protection water level, the motor is easy to burn out when exposed to the water surface. Because the shut-down water level is high, the start-up water level is higher, and the sewage and dirt are very seriously precipitated. Therefore, on one hand, the flow speed of inflow water is reduced and the inflow water is stagnant, and sewage and dirt in the water inlet pipeline are precipitated to cause the inlet of the rainwater and sewage pump to be blocked.

2. In the process of using a pump station, the water collecting tank is shut down to protect water below the water level for a long time, so that sewage and dirt are precipitated and fermented for a long time, in the process of fermenting the dirt, the oxygen consumption decomposition of organic matters enables the oxygen consumption rate in the water to be greater than the reoxygenation rate, so that the water is anoxic, the degradation of the organic matters is incomplete and the speed is reduced, odorous substances such as hydrogen sulfide, amine, ammonia, mercaptan and the like are generated in the anaerobic biodegradation process, and simultaneously, black substances such as FeS, MnS and the like are formed, so that the biochemical phenomenon of black and odorous occurs in the water. And because the silt is required to be lowered to the bottom of the pool during the maintenance, serious liability accidents of safety production are caused by the problems of dredging and maintenance every year.

3. The existing submersible sewage pump has the defects of complicated structure, poor interchangeability, inconvenient maintenance, short inspection and maintenance period, need of returning to a factory for maintenance and the like.

Therefore, how to design a pump station which can conveniently dredge and can dredge the bottom of the pool without personnel going down to the bottom of the pool becomes the problem to be solved urgently at present.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art.

It is therefore an object of the present invention to provide a hidden danger free pump station.

The invention provides a hidden danger-free pump station, which is used for being installed below a pump pool opening, and comprises a pump body and a lifting device, wherein the pump body is installed in a pump station pool, the lifting device comprises a pump cover, the pump cover and the pump body can be separated or coupled through an automatic coupling device, the automatic coupling device can separate and couple the pump cover and the pump body above the pump pool opening, and when the pump cover is separated from the pump body, the lifting device can be lifted and extracted out of the pump station pool outside the pump pool opening; the bottom of the pump body is provided with a pump suction inlet, and after the lifting device is pulled out to the pump station pool, the grabbing device can be inserted from the pump pool opening, penetrates through the pump suction inlet and stretches into the pump station pool to grab dirt at the pump suction inlet.

The hidden danger-free pump station provided by the embodiment of the invention comprises the drainage pump, wherein the drainage pump is arranged below a pump pool opening, and the pump pool opening can be a well opening of an integrated pump station and also can be other inlets of wells, pits, holes and the like which need to be used for the drainage pump. And the drainage pump is used for draining sewage in wells, pits, holes and the like. The drainage pump is a lift pump with a pump cover coupled with the pump body. This kind of drain pump, after it installs in the pump station pond, can be in pump pond mouth top, also subaerial, promote hoisting device such as pump cover, motor and rotation assembly to pump pond mouth top as a whole to realize dismantling of hoisting device such as pump cover, motor and rotation assembly more than ground. This kind of setting owing to connect pump cover and the pump body through automatic coupling device dismantlement, can realize the quick dismantlement of pump cover and the pump body like this outside the pump station pond (the top of pump pond mouth, also ground), quick desilting need not to return the factory and overhauls to this makes and can realize opening of the pump body at the pump station scene, and then dismantles the hoisting device of drain pump, and this has created the condition for subsequent mode such as through grabbing device is decontaminated. Simultaneously, in this application, when the installation drain pump and form the pump station, do not install the filter screen at pump suction inlet, also promptly, the pump sunction inlet opens completely and sets up, is promoted at the hoisting device of drain pump like this and demolishs, just makes in the pull throughs etc. of outside can insert the pump body from ground, then stretches out in the pump station pond through the pump sunction inlet to snatch the clearance to the filth of pump suction inlet. Particularly, this kind of pump station, after the pump station uses a period, can go up the hoisting device that constitutes pump cover, motor, rotation assembly etc. and then carry out initiative dredging that decontaminates to the pump sunction inlet through grabbing device (grabbing device here can be the special device that the pump station disposed in advance, also can be the structure of the hook class that the maintainer looked for temporarily) etc. to avoid the pump sunction inlet to block up because of long-time not clearing up. This kind of setting, in the drain pump use, when the great filth is adhered to the drain pump sunction inlet, can directly open the pump pond mouth, then lift the hoisting device including the pump cover and demolish, then alright through the grabbing device of looking for temporarily or special configuration clear away the filth of drain pump suction inlet. This kind of setting need not the personnel and just can overhaul the pump at the bottom of going to the effluent water sump, has improved maintainer's operational environment on the one hand, and on the other hand, be in encapsulated situation in the pump station pond for a long time, there are poisonous and harmful gas such as some carbon monoxide, chlorine in the unavoidable, consequently, the pump station personnel go down to the pond and low also arouse incident such as poisoning easily. And this application, decontaminate on ground, need not personnel and go down to the sewage bottom of a pool, thoroughly solved the security problem that maintainer entered into the bottom of a pool and exists. Simultaneously, this kind of mode for the cleaning of pump station is than good operation, consequently, can carry out a lot of cleaning in advance, changes the pump station into the initiative cleaning of pump station because of blockking up the passive cleaning that has to go on after the pump station to this just can thoroughly solve the easy problem of blockking up of pump station, has greatly reduced the hidden danger of pump station, can realize to a certain extent not having hidden danger pump station.

In addition, in this application, the drain pump adopts body, lid coupling technique, but ground dismouting, desilting, and the maintenance is convenient, need not to return the factory and overhauls, safe and reliable.

Wherein, in current scheme, the drain pump of pump station is not the elevator pump of body lid coupling, therefore, the drain pump can't go up motor, rotor etc. with promoting alone on the ground, and this is current scheme, must go up whole pump lift and carry out the reason of decontaminating. In addition, in the existing scheme, the filter screen for filtering is installed at the suction port of the pump, so that the grabbing device and the like cannot be extended out of the pump pool from the suction port from the ground due to the existence of the filter screen, and the existing pump station cannot be cleaned on the ground. And in this application, the cooperation of these two characteristics of filter screen based on body lid coupling elevator pump and cancellation pump suction entrance in right time for the pump station can be cleaned dirt subaerially completely, and need not promote the drain pump completely and go up, and need not descend the maintainer to the pump station pond in.

Further, in order to improve the convenience of cleaning, the drain pump may be provided as a special pump capable of pumping out the water at the bottom of the sump, i.e., a pump not requiring the start-up of the water level and the safe water level. Therefore, after the water at the bottom of the pool is pumped to be dry, the pump suction inlet can be exposed outside, and therefore convenience is provided for grabbing dirt at the pump suction inlet through a grabbing device and the like on the ground. The pump in the existing scheme generally needs to start the water level and stop the water level to protect the water level, and can not completely pump water, so that the dirt is dispersed in the rest water in a dispersing way, and is not easy to gather at a pumping inlet. This is also an existing pump station and does not consider another reason for decontamination on the ground. Certainly, in the actual process, set up the pump to ordinary stealthily dirty pump, it is also can, at this moment, promote the back at the hoisting device of drain pump, also can stretch out grabbing device by the pump sunction inlet to snatch the filth, exactly the maintainer is subaerial, can't see the bottom of the pool, can lead to the efficiency of decontaminating relatively lower, certainly, in this kind of scheme, the filth concentration degree is lower, also can lead to the efficiency of decontaminating relatively lower, but this kind of scheme itself is possible, it also belongs to the protection scope of this application.

In the above technical solution, the hidden danger free pump station further comprises: the water collecting tank is arranged at the bottom of the pump station pool, and the pump suction inlet is positioned in the water collecting tank.

In the technical scheme, the water collecting tank is arranged at the bottom of the pump station pool, so that dirt and the like can be gathered in the water collecting tank through the water collecting tank, and particularly when the drainage pump is a pump which does not reserve a starting water level and a stopping protection water level in advance, the water collecting tank is arranged to enable the height of the dirt to be highly concentrated in the water collecting tank, so that the dirt cleaning efficiency of an overhaul worker on the ground through a grabbing device and the like can be greatly improved.

Wherein the water collection tank is a trapezoidal water collection tank, of course, water collection tanks of other shapes are also possible. The insertion depth of the pump suction inlet in the water collecting tank can be reasonably set according to needs, and the width, the diameter and the like of the water collecting tank can also be set according to actual needs. When the optimal depth, width and diameter are designed, the pool bottom can be sucked to be empty, and the top of the water collecting tank is just exposed.

In the above technical solution, the hidden danger free pump station further comprises: the pumping device can be installed in the pump station pool through the pump pool port and can be lifted and pumped out of the pump station pool outside the pump pool port; accomodate the bag, accomodate the open end of bag and install in pump pond mouth department, accomodate the bottom cover of bag and establish and install on draw-out device, accomodate the bag and be used for upwards promoting when drawing-out device, the draw-out device is lived in the parcel.

Of course, the drawing device such as the lifting device and the gripping device may be any component capable of being lifted and drawn above the pump pool opening, that is, on the ground (for example, an externally arranged gripping device for dredging the suction opening of the drain pump). And this kind of part is owing to use in the pump station pond, consequently, when it promoted, can carry certain sewage or filth, and this application is to such hoisting device, grabbing device class draw-out device, has installed in advance at pump pond mouth department and has accomodate the bag, specifically speaking, accomodate the open end of bag and install in pump pond mouth department, and pump pond mouth here can be the well head of integration pump station, also can be other entrances that need use well, pit, hole etc. to the drain pump. The bottom cover of accomodating the bag is established and is installed on draw-out device such as hoisting device, grabbing device, and when the maintainer was upwards promoted and demolishd draw-out device such as hoisting device, grabbing device, the bag of accomodating can be turned over downwards and parcel and live the position that draw-out device such as hoisting device, grabbing device are located the bag bottom below. The length of the storage bag is set according to the length of the part to be wrapped, namely the bottom mounting position of the storage bag is less than the length of the storage bag from the bottom of the extraction device such as the lifting device and the gripping device, so that the storage bag can be turned downwards to reversely wrap the lower part of the extraction device such as the lifting device and the gripping device. According to the arrangement, the storage bag is arranged outside the extracting devices such as the lifting device and the gripping device in a sleeved mode, so that when the extracting devices such as the lifting device and the gripping device are dismantled, the storage bag can be downwards folded to wrap the extracting devices such as the lifting device and the gripping device, a maintainer is prevented from contacting sewage, dirt and the like on the extracting devices such as the lifting device and the gripping device, and the health of the maintainer is guaranteed in the whole operation process. Simultaneously, this kind of setting can avoid maintainer and hoisting device, grabbing device etc. take out direct contact such as sewage on the device, filth, also can avoid hoisting device, grabbing device etc. take out sewage, filth etc. on the device and pollute ground to this has stopped harmful substance's such as virus, bacterium in sewage, the filth propagation. The safety of maintainers is ensured, and serious accidents of liability to safety production caused by the problems of dredging and overhauling can be greatly reduced.

Wherein, the extracting device such as the lifting device, the gripping device and the like wrapped by the storage bag can be specially processed according to the standard subsequently if necessary. The storage bag can be treated according to the relevant requirements. Of course, special handling may not be necessary when securing the extraction devices such as the lifting device, the gripping device, etc. as required. Particularly, when the drawing-out devices such as the lifting device and the grabbing device are a liftable assembly consisting of a pump cover, a motor, a rotating assembly and the like in the lifting pump coupled by the body cover, the liftable assembly can be simply treated and then be installed in the pump station pool again after the decontamination treatment is finished.

The number of the storage bags can be set according to the extraction devices to be lifted, and generally, the number of the storage bags and the extraction devices to be lifted are arranged in a one-to-one correspondence manner.

In a particular aspect, the extraction device comprises a lifting device and the receiving pocket comprises a first receiving pocket adapted to the lifting device. Namely, the withdrawing device comprises a lifting device, namely, a first containing bag is installed on the lifting device. This kind of setting, to the pump cover, the first bag of accomodating has still been installed in advance to the hoisting device of constituteing such as motor and rotation assembly, the open end of first bag of accomodating is installed at pump pond mouth department hermetically, the bottom of first bag of accomodating is fixed and the cover is established and is installed outside hoisting device (mainly outside the lifting rod), the lower extreme of hoisting device passes in the bottom back-fixing of first bag of accomodating to the pump pond promptly, also it is the suit on hoisting device's upper portion to be also whole first bag of accomodating, and when upwards promoting demolishs hoisting device, first bag of accomodating can reverse turn over a back parcel at hoisting device's lower part, with pollution ground such as sewage on avoiding hoisting device, the maintainer makes dirty, or give off toxic gas etc., with this, the operational environment of maintainer has just improved, the safety of cleaning has been ensured. Wherein, in this scheme, first collecting bag is mainly used for wrapping up the rotation assembly that motor, pump cover and motor are connected. This kind of structure uses a period of back at the pump station, can go up the hoisting device who constitutes such as pump cover, motor, rotation assembly promotes, then carries out the mediation of initiatively decontaminating to the pump sunction inlet through grabbing device etc. to avoid the pump sunction inlet to block up because of not clearing up for a long time. This kind of setting, in the drain pump use, when the great filth is adhered to the drain pump sunction inlet, can directly open the pump pond mouth, then lift the hoisting device including the pump cover and demolish, then alright clear away the filth of drain pump suction inlet through grabbing device. This kind of setting need not personnel and just can overhaul the pump at the bottom of the effluent water sump, has guaranteed maintainer's safety. Simultaneously, this kind of mode for the cleaning of pump station is than good operation, consequently, can carry out a lot of cleaning in advance, changes the pump station into the initiative cleaning of pump station because of blockking up the passive cleaning that has to go on after the pump station to this just can thoroughly solve the easy problem of blockking up of pump station, has greatly reduced the hidden danger of pump station, can realize to a certain extent not having hidden danger pump station.

In any of the above technical solutions, the hidden danger free pump station further includes a cooling channel, one end of the cooling channel is connected with an external water source or a drain pipe of the drain pump, that is, an inlet of the cooling channel is connected with the water source, and the other end of the cooling channel is arranged corresponding to a motor of the drain pump and used for cooling the motor. That is, the water discharged from the other end of the cooling passage can be applied to the motor to cool the motor of the drain pump.

In the technical scheme, water entering the cooling channel can act on the motor along the cooling channel, so that the motor is cooled. With this arrangement, the inlet of the cooling passage can be closed when the drain pump is started by flooding, so that the motor is cooled by the water in the pump station pool. And when the motor of the drainage pump exceeds the liquid level preset height, water can be supplied into the cooling channel, so that the motor is cooled by the water output by the cooling channel. This kind of setting for the motor both can submerge the start-up, also can expose the surface of water take the altitude to start, with this more thorough that just can be with the water discharge in pump station pond, so that remaining water level is lower in the pump station pond (can arrange water to the greatest extent basically), in order this just to solve current scheme, because the bottom of the pool water is not to the greatest extent and can form the potential safety hazard problem that thick silt and lead to at the bottom of the pool. In the existing scheme, the submersible sewage pump and the like can only be submerged and started, and the motor cannot expose out too much liquid level, so that more water cannot be drained in the pump station pool, namely the remaining sewage still has higher water level, namely the so-called shutdown protection water level. Therefore, it is very inconvenient to perform treatment such as cleaning, and thus thick sludge is formed on the bottom of the tank. And this application has solved through additionally setting up cooling channel for the motor, and the motor can't expose the liquid level and carry out the problem of long-time work, and then has ensured the drainage effect, has cancelled the shut down protection water level of drain pump and has flooded the required water level of start to this has just further improved on ground through grabbing device etc. the efficiency of decontaminating, has also further avoided the formation of bottom of the pool silt thing. Simultaneously, this kind of cooling method, for cooling from top to bottom, personnel also can control and overhaul cooling structure etc. subaerial, and are very convenient.

Furthermore, the drainage pump is a canned motor pump, and a magnetic fluid sealing device and an air-blocking and shielding device matched with the magnetic fluid sealing device are arranged in the canned motor pump.

In the technical scheme, the drainage pump is a shield pump, and a magnetic fluid sealing device and an air blocking shielding device matched with the magnetic fluid sealing device are arranged in the shield pump. Specifically, the canned motor pump comprises a motor and a water pump, and air sealing is carried out between the motor and the water pump through a magnetic fluid sealing device and an air blocking and shielding device, so that the problem that sewage flows into the motor to damage the motor in the drainage process of the water pump is avoided. Further, the outlet of the water pump is connected with a water drainage pipe, so that the water pump can drain sewage out of the pump station pool through the water drainage pipe under the driving of the motor.

Meanwhile, the drainage pump is a canned motor pump with a magnetofluid sealing device, namely the pump is a magnetofluid sealing air-blocking canned motor pump, and the specific structure of the pump can be referred to patent CN202020579246.X, an air-blocking canned motor pump and a vertical pump. The pump is sealed by the magnetic fluid, so that structures such as oil seal and oil lubrication are not needed in the use process, and the structures such as the oil seal and the oil lubrication are omitted, so that the pump is not easy to generate temperature rise in the use process, and the cooling requirement of the motor in the working process is greatly reduced. Therefore, the cooling water introduced by the additionally arranged cooling channel can meet the cooling requirement of the motor. And the motor in the current scheme all is the oil blanket motor, and the cooling capacity of its demand is great, consequently, the cooling water that utilizes the cooling channel of extra setting to let in can't satisfy the demand of oil blanket motor, consequently, in the current scheme, all sets the motor to submerge the motor of start-up, and does not adopt extra independent cooling channel to align and carry out extra cooling, so stealthily dirty pump in the current scheme all is provided with the shut down protection water level, and the strong pump is shut down, the protection water level. The pump can not expose the motor, and the motor can be burnt out. For a submersible sewage pump, the height of the pump is about three or four meters, the motor is generally five or six meters away from the bottom of the pool under the condition of adding a shutdown protection water level, namely in the conventional pump station, the submersible sewage pump does not pump when a water level with the height of five or six meters is left in a pump station pool, so that a large amount of sludge in the pump pool is precipitated. And after the pumping station finishes one-time pumping operation, the pumping station can wait until the sewage gathered in the pool of the pumping station is approximately close to the position of the pool bottom, and then the pumping station can pump water again, and more sludge, dirt and the like can be deposited on the bottom of the pool in the 'water storage' process. Over time, very tough dirt is formed at the bottom of the pump station pool. Therefore, the existing sewage pump station has great potential safety hazard in the use process. In the application, the magnetic fluid sealing air blocking shielding pump is adopted, so that the draining pump is not afraid of idling, the shutdown protection water level is not required to be designed, and water can be completely drained in the using process until the pump falls. Therefore, after water is drained, thick sediment can not be formed at the bottom of the pump station pool, and the potential safety hazard of the pump station is reduced. Simultaneously, this kind of setting, after the drain pump was taken out at every turn, just can initiatively carry out once ground and decontaminate the processing to this just can change the passive mode of decontaminating of pump station into initiative and decontaminate, with this can be bigger degree avoid the drain pump to block up. Simultaneously, in this application, because can all manage to find time the bottom of the pool at every turn, consequently, can pump the entrance with in gathering such as filth, like this on ground alright snatch through grabbing device etc. go to accomplish and decontaminate. In the existing scheme, although the pump can be lifted up integrally, the bottom of the pool cannot be pumped out, so that the sewage still floats in the whole pool and cannot be completely gathered, and therefore, in the existing scheme, the sewage still cannot be cleaned on the ground even after the whole pump is lifted up, and the pollution is scattered and floats in the pool and cannot be salvaged at all. And in this application, utilize canned motor pump and cooling channel to motor cooling's technique, can find time the bottom of the pool to this makes the filth can collect the pump suction entrance along with water reduces gradually, and maintainer only need stretch into grabbing device pump suction department on subaerial like this and can clean up the filth completely, just so avoided the bottom of the pool to form too thick silt thing. Meanwhile, the draining pump in the pump station has no shutdown to protect the water level limitation, can raise the elevation of the pool bottom, and saves the investment; and hoisting equipment, a pump room, heating and the like do not need to be fixed, so that the related cost is saved.

Wherein, the motor is installed to the lower extreme of lift bar, makes motor, pump cover etc. can promote subaerial and take out through the lift bar. Of course, the lifting bar may also be a lifting rope. Simultaneously, the upper end of lift bar is still installed anti-rotation device by fixed mounting in pump sump mouth department on it, can avoid rotation such as motor, pump cover, pump body through anti-rotation device. Of course, the lifting bar can also be provided with counter-pressure means. The motor is a driving device and is connected with the pump cover in an airtight mode through a motor support, meanwhile, the motor further comprises a motor shaft, and the output end of the motor shaft penetrates through a hole in the pump cover to be connected with a rotating assembly in the pump body so as to drive the rotating assembly to rotate.

Furthermore, a cooling channel is arranged in the lifting rod, one end of the cooling channel is connected with an external water source or a drain pipe of the drain pump, namely, an inlet of the cooling channel is connected with the water source, and the other end of the cooling channel is arranged corresponding to the motor of the drain pump and used for cooling the motor.

In this case, the cooling passages and the lift pins are provided together, so that the cooling water pipe is not additionally provided, thereby simplifying the overall structure.

Furthermore, a splitter plate is arranged at the top of the motor and used for receiving water conveyed by the cooling channel, and a plurality of splitter holes are formed in the splitter plate and can disperse the water on the splitter plate to the motor so as to cool the motor.
