Description

Novel negative pressure well

Technical Field

The utility model relates to a motor-pumped well technical field, in particular to novel negative-pressure well.

Background

The construction of current motor-pumped well uses the precast concrete pipe as the wall of a well more, and the well head is open or simply covers with prefabricated apron, has following problem:

(1) the prefabricated pipe links are bonded by concrete, and due to the influence of pressure and severe environment for a long time, the joints and the prefabricated pipes can be aged, so that the well wall is broken, silt flows into the bottom of the well, and finally the motor-pumped well cannot be used continuously;

(2) the prefabricated pipe well wall does not have a water seepage function, so that water in a relatively deep water layer from a ground surface, namely a water layer matched with the depth of the well wall, is mainly taken to ensure sufficient water source under normal conditions;

(3) most of existing motor-pumped well water pumps are deep water pumps, so that the water pumps are prevented from leaking out of the water surface due to water level reduction in drought seasons, the depths of the water pumps are relatively deep in most of cases, the power of the water pumps needs to be improved, the energy consumption is increased, and meanwhile, the investment of pipes and cables is increased;

(4) most of the existing motor-pumped wells are open well mouths, certain potential safety hazards exist, and cases that people fall into the motor-pumped wells in these years sometimes occur; the open wellhead is also easy to fall into animal carcasses such as snakes and mice, pesticide bottles and other garbage, and the water source is polluted;

(5) because the pipeline is relatively long, the water pump is continuously collided with the well wall due to the vibration of the water pump and other reasons, the service life of the water pump and the motor-pumped well is shortened, the service life promised by the existing motor-pumped well construction party is mostly 10-20 years, but the service life of most motor-pumped wells is 5-10 years due to various reasons in the practical application process.

Disclosure of Invention

In order to solve the problems of the prior art, the utility model provides a novel negative-pressure well of simple structure, long-life.

The technical scheme of the utility model as follows:

the utility model provides a novel negative-pressure well, includes the infiltration wall of a well and the sealed wall of a well on upper portion of the lower part, the top of the sealed wall of a well be equipped with sealed lid, sealed lid on set up the outlet, one side of outlet be equipped with the negative-pressure device, the middle part of sealed lid be equipped with the pipeline of connecting the water pump.

And sealing covers are arranged on the water discharge opening and the pipeline.

And seepage holes are uniformly distributed on the seepage well wall.

The utility model provides a beneficial effect that technical scheme brought is:

(1) the installation is simple and convenient;

(2) the cost is reduced: because the water level in the well is fixed, the deep water pump is placed closer to the ground, so that pipes and cables are saved, the power of the water pump can be reduced, and the aim of saving energy is fulfilled;

(3) safety: because the well head is sealed, the occurrence of a water falling event and a water source pollution event is prevented;

(4) the service life of the motor-pumped well is prolonged, the environment is relatively stable due to the sealing in the well, the service life of the motor-pumped well can be prolonged, and the service life of the negative pressure motor-pumped well is 10-20 years;

(5) prolonging the service life of the water pump: because the environment in the well is stable, and the water pump is close to the ground, the pipe is short, the phenomenon that the water pump collides with the well wall due to vibration is reduced in the working process, and the service life of the water pump can be prolonged;

(6) the water source is freely selected: because of the water seepage well wall, the water source supply of the negative pressure type motor-pumped well is that the water of each water layer can be obtained, is not limited to the water at the bottom of the well, and increases the water yield of the motor-pumped well;

(7) backwashing: after the infiltration mouth is blocked by silt, as long as open the pressure release mouth of sealed well lid, under the effect of rivers, wash the infiltration mouth automatically, simple and convenient prevents to lead to the abandonment of motor-pumped well condition because silt is piled up.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in figure 1, a novel negative pressure well comprises a water seepage well wall 1 at the lower part and a sealing well wall 2 at the upper part, wherein a sealing cover 3 is arranged at the top of the sealing well wall 2, a water drainage opening 4 is formed in the sealing cover 3, a negative pressure device 5 is arranged on one side of the water drainage opening 4, and a pipeline 7 connected with a water pump 6 is arranged in the middle of the sealing cover 3.

And sealing covers 3 are arranged on the water discharge opening 4 and the pipeline 7.

And the water seepage well wall 1 is uniformly provided with water seepage holes.

After sealed wall of a well 2, the infiltration wall of a well 1 and the 6 installation and debugging of water pump are accomplished, reduce the internal gas pressure of well with negative pressure ware 5, form the negative pressure in sealed wall of a well 1, let the water level promote to the assigned height, no matter the outer water level of the wall of a well rises or descends, all can let sealed wall of a well 2 internal water level unchangeable, prevent that 6 surfaces of water pump from causing 6 damages of water pump to can fix 6 areas nearer from the ground with water pump.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
