Description

Technical Field

[0001] The utility model relates to the technical field of pump station operation, in particular to an integrated pump station control cabinet. Background Art

[0002] Integrated pumping station usually refers to integrated prefabricated pumping station. Integrated prefabricated pumping station is a lifting equipment for sewage, rainwater, drinking water and wastewater. It is a pressure pumping station that is uniformly produced and assembled by the factory and then transported to the site for installation.

[0003] The integrated pump station includes a base, a cylinder and a top cover. A submersible pump is arranged in the cylinder. A water inlet and a water outlet are arranged on the cylinder. The water outlet of the submersible pump is connected to a drain pipe, which extends to the outside of the cylinder through the water outlet. The cylinder is usually also provided with a liquid level sensor for detecting the water level in the cylinder. There is also a matching control cabinet equipment outside the integrated pump station. The control cabinet is equipped with a controller electrically connected to the liquid level sensor and the submersible pump respectively. When the liquid level sensor detects that the water level inside the cylinder rises to a certain height, the controller automatically controls the submersible pump to start drainage, thereby realizing the automatic operation of the pump station.

[0004] In the related art, the pump station is usually buried under the ground outdoors, and the control cabinet equipment of the pump station is usually set on the top of the cylinder or on the ground on one side of the cylinder. The control cabinet is generally not installed inside the cylinder because the internal space of the cylinder is small and the ventilation is poor. There are multiple electrical components inside the control cabinet. The electrical components will generate heat during operation, which is not conducive to the heat dissipation of the control cabinet. In addition, the humidity inside the cylinder is high, which is not conducive to the normal operation of the electrical components. However, the control cabinet will be exposed to direct sunlight when placed in the open air, causing the control cabinet shell to be heated and the temperature to rise, which is not conducive to the heat dissipation of the electrical components inside it. Poor heat dissipation of the electrical components will lead to a decrease in their working performance, such as a slower response speed of the controller, and will also accelerate the aging of the line and shorten the service life of the electrical components. Utility Model Content

[0005] The utility model aims to provide an integrated pump station control cabinet to improve the problem of poor heat dissipation effect of the control cabinet of the integrated pump station.

[0006] The utility model is realized by the following technical solutions:

[0007] An integrated pump station control cabinet, the pump station includes a cylinder and a submersible pump arranged inside the cylinder, the pump outlet of the submersible pump is connected with a drain pipe, the control cabinet includes a cabinet, a water pump controller is arranged in the cabinet, the water pump controller is electrically connected to the submersible pump, an electric valve is arranged on the drain pipe, a valve controller is arranged in the cabinet, the electric valve is electrically connected to the valve controller, a water pipe is connected on the drain pipe between the electric valve and the submersible pump, and the water pipe extends to the outside of the cylinder; a hot water exchange pipe is arranged inside the cabinet, one end of the hot water exchange pipe is connected with the water pipe after passing through the side wall of the cabinet, and the other end is connected with a return pipe after passing through the side wall of the cabinet, and the return pipe is connected to the cylinder.

[0008] Furthermore, the water pump controller includes a frequency converter, the submersible pump is a variable frequency submersible pump, and the submersible pump is electrically connected to the frequency converter.

[0009] Furthermore, a filter tube is provided on the pipe section of the water pipe located outside the cylinder, both ends of the filter tube are connected to the water pipe at the corresponding ends through flanges, and a filter screen is provided in the filter tube.

[0010] Furthermore, one end of the water pipe located outside the cylinder is wrapped with a heat insulation layer, and the heat insulation layer is wrapped with aluminum foil.

[0011] Furthermore, an anti-radiation coating layer is provided on the outer wall of the control cabinet.

[0012] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0013] In the utility model, the liquid level sensor in the pump station monitors the water level inside the cylinder. When the water level is lower than the preset value, the liquid level sensor transmits a signal to the valve controller, and the valve controller controls the electric valve to close. When the submersible pump is running, the accumulated water in the cylinder is transported to the hot water exchange pipe through the drainage pipe and the water delivery pipe. When the cold water in the hot water exchange pipe passes through the control cabinet, it will exchange heat with the air inside the cabinet through the hot water exchange pipe, which is convenient for heat exchange and cooling of the control cabinet. Especially when the internal temperature of the control cabinet is high when it is directly exposed to the sun, this heat exchange effect is better. Since the cylinder is usually in Below the ground, the accumulated water inside the cylinder can exchange heat with the surrounding underground soil through the cylinder, so that the water temperature inside the cylinder can be reduced and restored; when the water level is higher than the preset value, the liquid level sensor transmits a signal to the valve controller, and the valve controller controls the electric valve to open. At this time, the submersible pump can discharge the accumulated water inside the cylinder out of the cylinder through the drain pipe. While draining, a part of the accumulated water can still supply water to the hot water exchange pipe through the water pipe until the water level is lower than the preset value, then the valve controller closes the electric valve. At this time, the submersible pump is only used to dissipate heat and supply water to the control cabinet. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the embodiments and drawings. The schematic implementation mode and description of the utility model are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual development and use stage.

[0021] Example 1

[0022] An integrated pump station control cabinet, refer to Figure 1 , Figure 2 The pump station includes a cylinder 1 and a submersible pump 2 arranged inside the cylinder 1, a drain pipe 3 is connected to the pump outlet of the submersible pump 2, the control cabinet includes a cabinet 4, a water pump controller is arranged in the cabinet 4, the water pump controller is electrically connected to the submersible pump 2, an electric valve 5 is arranged on the drain pipe 3, a valve controller is arranged in the cabinet 4, the electric valve 5 is electrically connected to the valve controller, a water pipe 6 is connected on the drain pipe 3 between the electric valve 5 and the submersible pump 2, and the water pipe 6 extends to the outside of the cylinder 1; a hot water exchange pipe 7 is arranged inside the cabinet 4, one end of the hot water exchange pipe 7 passes through the side wall of the cabinet 4 and is connected to the water pipe 6, and the other end passes through the side wall of the cabinet 4 and is connected to a return pipe 8, and the return pipe 8 is connected to the cylinder 1.

[0023] The liquid level sensor in the cylinder 1 monitors the water level inside the cylinder 1. When the water level is lower than the preset value, the liquid level sensor transmits a signal to the valve controller, and the valve controller controls the electric valve 5 to close. When the submersible pump 2 is running, the accumulated water in the cylinder 1 is transported to the hot water exchange pipe 7 through the drain pipe 3 and the water pipe 6. When the cold water in the hot water exchange pipe 7 passes through the control cabinet, it will exchange heat with the air inside the cabinet 4 through the hot water exchange pipe 7, which is convenient for heat exchange and cooling of the control cabinet. In particular, when the internal temperature of the control cabinet is high when it is directly exposed to the sun, this heat exchange effect is better. Since the cylinder 1 is usually located below the ground, the accumulated water inside it can be discharged through the cylinder 1 and the surrounding underground soil. Heat exchange can reduce the water temperature inside the cylinder 1 and restore it. It is measured that during the daytime in summer, the soil temperature 3 meters above the ground is only about 10°C; when the water level is higher than the preset value, the liquid level sensor transmits a signal to the valve controller, and the valve controller controls the electric valve 5 to open. At this time, the submersible pump 2 can discharge the accumulated water inside the cylinder 1 out of the cylinder 1 through the drain pipe 3. While draining, a part of the accumulated water can still be supplied to the hot water exchange pipe 7 through the water pipe 6 until the water level is lower than the preset value. The valve controller closes the electric valve 5. At this time, there is still a certain height of accumulated water in the cylinder 1, and the submersible pump 2 is only used to dissipate heat and supply water to the control cabinet.

[0024] Example 2

[0025] The difference between this embodiment and embodiment 1 is that in this embodiment, referring to Figure 1 , Figure 2 The water pump controller includes a frequency converter, the submersible pump 2 is a variable frequency submersible pump 2, and the submersible pump 2 is electrically connected to the frequency converter; when the water level is lower than the preset value, the liquid level sensor transmits a signal to the frequency converter, and the frequency converter automatically reduces the speed of the submersible pump 2, thereby reducing the output water pressure of the submersible pump 2, so that the submersible pump 2 can meet the water supply to the hot water exchange pipe 7, which is beneficial to reducing the water pressure burden of the water delivery pipe 6 and the hot water exchange pipe 7, and is also beneficial to energy saving. The other structures of this embodiment are the same as those of embodiment 1, so they are not repeated here.

[0026] Example 3

[0027] The difference between this embodiment and embodiment 1 is that in this embodiment, referring to Figure 1 , Figure 2, a filter tube 9 is connected to the pipe section of the water delivery pipe 6 located outside the cylinder 1, and both ends of the filter tube 9 are connected to the water delivery pipe 6 at the corresponding end through a flange 10, and a filter screen 11 is arranged in the filter tube 9; since the accumulated water is usually rainwater, it is inevitable that there are impurities such as mud in the accumulated water, and the mud is easily transported to the hot water exchange pipe 7 and then precipitated in the hot water exchange pipe 7, which will reduce the heat exchange performance of the hot water exchange pipe 7. The filter screen 11 can reduce the situation where mud impurities enter the hot water exchange pipe 7. The filter screen 11 can be cleaned by removing the flange 10. The other structures of this embodiment are the same as those of embodiment 1, so they are not repeated here.

[0028] Example 4

[0029] The difference between this embodiment and embodiment 1 is that in this embodiment, referring to Figure 1 , Figure 2 The end of the water pipe 6 located outside the cylinder 1 is wrapped with a heat insulation layer 12. The heat insulation layer 12 can be made of glass fiber, quartz wool, silicate and other materials. The heat insulation layer 12 is wrapped with aluminum foil. The aluminum foil can reflect sunlight. The heat insulation layer 12 can isolate external heat and reduce the temperature of accumulated water caused by direct sunlight on the water pipe 6, thereby affecting the cooling effect of accumulated water on the control box. The other structures of this embodiment are the same as those of embodiment 1, so they are not repeated here.

[0030] Example 5

[0031] The difference between this embodiment and embodiment 4 is that in this embodiment, reference Figure 1 , Figure 2 The outer wall of the cabinet body 4 is provided with an anti-radiation coating layer, which can reflect more heat radiation, which is beneficial to reduce the temperature of the control cabinet surface. The other structures of this embodiment are the same as those of embodiment 4, so they are not repeated here.
