Description

Technical Field

[0001] The invention relates to the technical field of prefabricated pump stations, and in particular to an integrated prefabricated pump station. Background Art

[0002] In water supply and drainage and related fields, the application of integrated prefabricated pump stations is becoming more and more widespread. It integrates a variety of equipment and provides convenience for the transportation and treatment of water resources. However, with the popularization of its use, some problems have gradually emerged, among which the problem of self-cleaning is particularly prominent.

[0003] However, after the current integrated prefabricated pump station has been in operation for a period of time, various impurities, dirt and sediments will inevitably accumulate inside. They will hinder the smooth passage of water, reduce the drainage efficiency of the pump station, and may also corrode the equipment, affect the performance and life of the equipment, and thus increase the maintenance cost and equipment failure rate. In solving the problem of cleaning inside the pump station, the existing methods have many inconveniences. On the one hand, the traditional manual cleaning method requires a lot of manpower and time, and it is difficult to operate in the limited space inside the pump station, and there are certain safety risks. On the other hand, some existing cleaning equipment or methods are difficult to comprehensively and effectively clean every corner inside the pump station, and cannot adapt to the complex structure of the pump station and the cleaning needs of different positions. For example, the dirt in some corners and gaps is difficult to remove, resulting in unsatisfactory cleaning effect. In addition, the existing cleaning methods often require the pump station to be shut down for operation, which will interrupt the normal water supply and drainage work and bring inconvenience to production and life. In summary, the self-cleaning problem of the integrated prefabricated pump station needs to be solved urgently to improve its operation stability and efficiency, reduce maintenance costs and the impact on normal work. Summary of the invention

[0004] In order to overcome the deficiencies in the prior art, the present invention provides an integrated prefabricated pump station, which can perform self-cleaning on the interior of the prefabricated pump station.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] An integrated prefabricated pump station includes an outer shell, an installation partition and a self-cleaning device, wherein the installation partition divides the inner cavity of the outer shell into an upper electrical installation cavity and a lower water storage cavity, and the self-cleaning device includes a driving motor, a lifting mechanism and a water spray assembly connected to the lifting mechanism, the upper end of the lifting mechanism is installed above the installation partition, the lifting mechanism passes through the installation partition and extends downward, the driving motor is transmission-connected to the upper end of the lifting mechanism, the water spray assembly is arranged below the installation partition, and the water spray assembly includes at least one nozzle, and the nozzle faces the inner wall of the lower water storage cavity.

[0007] In the above technical solution, the mounting partition divides the inner cavity of the housing into an upper electrical installation cavity and a lower water storage cavity, and the internal electrical components can be arranged in the upper electrical installation cavity to avoid contact with sewage and water vapor in the lower water storage cavity, thereby increasing the reliability and stability of the electrical components. The lifting mechanism in the self-cleaning device can drive the water spray assembly to move up and down to self-clean the inner wall of the lower water storage cavity and the equipment arranged in the lower water storage cavity.

[0008] Preferably, the lifting mechanism includes a screw, a nut, a guide plate and a mounting frame, the nut is threadedly connected to the screw, the mounting frame is connected to the nut, the nozzle is mounted on the mounting frame, the guide plate is fixed to the mounting baffle and is arranged side by side with the screw, a guide groove is provided on the guide plate, a guide rod passing through the guide groove and adapted to the guide groove is installed on the mounting frame so that the guide rod can slide along the guide groove, the guide groove includes a left oblique groove and a right oblique groove which are inclined relative to the vertical direction, the inclination directions of the left oblique groove and the right oblique groove are opposite, and a plurality of left oblique grooves and a plurality of right oblique grooves are connected end to end in sequence and are connected.

[0009] In the above technical solution, the inclination directions of the left and right chute are opposite, which means that the left chute is inclined to the left, and the right chute is inclined to the right. The specific inclination angles of the two can be different or the same, as long as the guide rod can swing back and forth when moving between the two. The working principle of the above technical solution is: the drive motor drives the screw rod to rotate, and when the screw rod rotates, it drives the nut and the mounting frame to move up and down. Since the guide rod passes through the guide groove, when the mounting frame moves up and down, it drives the mounting frame to swing left and right, so that the nozzle can swing left and right to perform a wider range of cleaning. The above solution still only needs one driving source to realize the up and down movement and left and right swing of the water spray assembly, and the driving source can be arranged above the mounting baffle, and is not affected by the sewage and water vapor in the lower water storage chamber.

[0010] Preferably, the mounting frame includes a fixed plate and a movable plate, the nozzle is hinged to the fixed plate, the guide rod is slidably connected to the fixed plate in the vertical direction, one end of the guide rod is fixed to the movable plate, the other end of the guide rod passes through the fixed plate and is connected to the nozzle, so that the guide rod drives the nozzle to swing up and down, the diameter of the guide rod at the corresponding position of the guide groove is smaller than the width of the guide groove, so that the guide rod has a vertical movable space in the guide groove, and a guide piece adapted to the guide groove is fixed on the fixed plate, so that the fixed plate can slide along the guide groove.

[0011] In the above technical solution, the adaptation of the guide member to the guide groove means that the width of the guide member is the same as the width of the guide groove. Since the diameter of the corresponding position of the guide rod and the guide groove is smaller than the width of the guide groove, when the screw rod drives the nut to move downward, the movable plate drives the guide rod to move downward, and since the fixed plate is provided with a guide piece adapted to the guide groove, the fixed plate is fixed at this time, and the guide rod drives the nozzle to swing downward or upward, thereby changing the up and down direction of the nozzle, and when the guide rod moves to the lower limit position, it can only move obliquely downward along the inclination direction of the guide groove, and at this time, the nut drives the movable plate, the guide rod, the fixed plate and the nozzle to move obliquely downward together for water spray cleaning; when the screw rod drives the nut to move upward, the movable plate drives the guide rod to move upward, and since the fixed plate is provided with a guide piece adapted to the guide groove, the fixed plate is fixed at this time, and the guide rod drives the nozzle to swing upward or downward, thereby changing the up and down direction of the nozzle, and when the guide rod moves to the upper limit position, it can only move obliquely upward along the inclination direction of the guide groove, and at this time, the nut drives the movable plate, the guide rod, the fixed plate and the nozzle to move obliquely upward together for water spray cleaning. The above technical solution can make the nozzle have different orientations during the upward and downward movement of the mounting frame, thereby increasing the vertical cleaning range of the nozzle, shortening the lifting height of the lifting mechanism, reducing costs, and making the lower end of the lifting mechanism away from the sewage at the bottom. The above solution still only needs one driving source to realize the up and down movement, left and right swinging of the water spray assembly and the up and down swinging of the nozzle, and the driving source can be set above the mounting partition, and is not affected by the sewage and water vapor in the lower water storage chamber.

[0012] Preferably, a horizontal groove extending in the horizontal direction is provided on the nozzle, a connecting rod is fixed to one end of the guide rod away from the movable plate, and one end of the connecting rod extends into the horizontal groove and can slide relative to the horizontal groove.

[0013] In the above technical solution, the connection between the guide rod and the nozzle can be realized, so that the up and down movement of the guide rod can drive the nozzle to swing up and down.

[0014] Preferably, the hinge point between the nozzle and the fixed plate is the first position, the water outlet of the nozzle is the second position, and the connecting rod is arranged between the first position and the second position; or, the first position is arranged between the connecting rod and the second position.

[0015] In the first solution, since the moving direction of the connecting rod relative to the fixed plate is consistent with the swinging direction of the nozzle relative to the fixed plate, the nozzle can be directed obliquely upward when the mounting frame moves from bottom to top, and the nozzle can be directed obliquely downward when the mounting frame moves from top to bottom. The water flow direction is inclined toward the inner wall, and the water flow is sprayed from the cleaned side to the uncleaned side, so as to better clean the bottom of the area to be cleaned. In the second solution, the water flow direction can be tilted toward the inner wall, so as to better clean the bottom of the area to be cleaned.

[0016] Preferably, the number of the guide plates is two, the two guide plates are arranged on opposite sides of the screw rod, and the two guide plates are connected to corresponding guide rods; and / or the number of the guide rods is multiple, and the multiple guide rods arranged on the same guide plate are spaced apart in the vertical direction. The above technical solution can make the guide structure more stable.

[0017] Preferably, a rotating wheel is sleeved at a position of the guide rod corresponding to the guide groove, and the rotating wheel is rotatably connected to the guide rod. The solution can reduce the wear between the guide rod and the guide groove.

[0018] Preferably, the guide plate is an arc-shaped plate, the axis of which coincides with the axial direction of the screw rod; the diameter passing through the axis of the arc-shaped plate is the first diameter, and in the side wall of the right inclined groove or the left inclined groove, the side wall position passing through the same first diameter has the same height.

[0019] In the above technical solution, the arc plate can better adapt to the mounting frame and better guide the mounting frame. The side walls passing through the same first diameter have the same height to ensure that in the extension direction of the guide rod, the side walls of the right bevel groove or the left bevel groove have the same height, so that the guide rod contacts more side walls, the contact surface is larger, and it is less prone to wear.

[0020] Preferably, the number of the nozzles is multiple, and the multiple nozzles are arranged in an array in the vertical direction and the horizontal direction. The solution can increase the water spray cleaning area and the cleaning effect.

[0021] Preferably, a water pump and a switching valve are provided in the lower water storage chamber, the water pump is connected to the water inlet of the switching valve through a pipeline, one of the outlets of the switching valve is connected to the water outlet pipe through a pipeline, the other outlet of the switching valve is connected to the nozzle through a pipeline, a filter is provided between the switching valve and the nozzle, and the switching valve and the filter are both installed in the upper electrical installation chamber. The solution can use the water pump to supply water to the water spray assembly.

[0022] The beneficial effects of the present invention are as follows: (1) The mounting baffle divides the inner cavity of the housing into an upper electrical installation cavity and a lower water storage cavity, and the internal electrical components can be arranged in the upper electrical installation cavity to avoid contact with the sewage and water vapor in the lower water storage cavity, thereby increasing the reliability and stability of the electrical components. The lifting mechanism in the self-cleaning device can drive the water spray assembly to move up and down, and self-clean the inner wall of the lower water storage cavity and the equipment arranged in the lower water storage cavity. (2) Only one driving source is required to realize the up and down movement and left and right swing of the water spray assembly, and the driving source can be arranged above the mounting baffle, and is not affected by the sewage and water vapor in the lower water storage cavity. (3) During the upward and downward movement of the mounting frame, the nozzle can have different orientations, thereby increasing the up and down cleaning range of the nozzle, shortening the lifting height of the lifting mechanism, reducing costs, and at the same time making the lower end of the lifting mechanism away from the sewage at the bottom. The above scheme still only requires one driving source to realize the up and down movement, left and right swing of the water spray assembly and the up and down swing of the nozzle, and the driving source can be arranged above the mounting baffle, and is not affected by the sewage and water vapor in the lower water storage cavity. (4) The arc-shaped plate can better adapt to the mounting frame and better guide the mounting frame. The side walls passing through the same first diameter have the same height to ensure that the side walls of the right inclined groove or the left inclined groove have the same height in the extension direction of the guide rod, so that the guide rod contacts more side walls, the contact surface is larger, and it is less prone to wear.

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Embodiment 1:

[0032] like Figures 1 to 6 As shown, an integrated prefabricated pump station includes a shell 1, a mounting baffle 2 and a self-cleaning device 3. The mounting baffle 2 divides the inner cavity of the shell 1 into an upper electrical installation cavity 11 and a lower water storage cavity 12. The upper electrical installation cavity 11 is located above the mounting baffle 2, and the lower water storage cavity 12 is located below the mounting baffle 2. The self-cleaning device 3 includes a driving motor 31, a lifting mechanism 32 and a water spray assembly 33 connected to the lifting mechanism 32. The upper end of the lifting mechanism 32 is installed above the mounting baffle 2. The lifting mechanism 32 passes through the mounting baffle 2 and extends downward. The driving motor 31 is in transmission connection with the upper end of the lifting mechanism 32. The water spray assembly 33 is arranged below the mounting baffle 2. The water spray assembly 33 includes at least one nozzle 331, and the nozzle 331 faces the inner wall of the lower water storage cavity 12. The shell 1 is provided with a water inlet pipe 4 and a water outlet pipe 5, and the water inlet pipe 4 and the water outlet pipe 5 both extend into the lower water storage cavity 12.

[0033] In the above technical solution, the mounting partition 2 divides the inner cavity of the housing 1 into an upper electrical installation cavity 11 and a lower water storage cavity 12, and the internal electrical components can be arranged in the upper electrical installation cavity 11 to avoid contact with sewage and water vapor in the lower water storage cavity 12, thereby increasing the reliability and stability of the electrical components. The lifting mechanism 32 in the self-cleaning device 3 can drive the water spray assembly 33 to move up and down, and self-clean the inner wall of the lower water storage cavity 12 and the equipment arranged in the lower water storage cavity 12.

[0034] Preferably, the lifting mechanism 32 includes a screw rod 321, a nut 322, a guide plate 323 and a mounting bracket 324, the screw rod 321 is rotatably connected to the mounting baffle 2, the drive motor 31 is transmission-connected to the upper end of the screw rod 321, the nut 322 is threadedly connected to the screw rod 321, the mounting bracket 324 is connected to the nut 322, the nozzle 331 is installed on the mounting bracket 324, the guide plate 323 is fixed to the mounting baffle 2 and arranged side by side with the screw rod 321, and the guide plate 323 is fixed to the mounting baffle 2 and arranged side by side with the screw rod 321. A guide groove 3231 is provided on the plate 323, and a guide rod 3241 passing through the guide groove 3231 and adapted to the guide groove 3231 is installed on the mounting frame 324, so that the guide rod 3241 can slide along the guide groove 3231, and the guide groove 3231 includes a left oblique groove 3231 and a right oblique groove 3231 inclined relative to the vertical direction, and the inclination directions of the left oblique groove 3231 and the right oblique groove 3231 are opposite, and a plurality of left oblique grooves 3231 and a plurality of right oblique grooves 3231 are connected end to end in sequence and are connected.

[0035] In the above technical solution, the inclination directions of the left inclined groove 3231 and the right inclined groove 3231 are opposite, which means that the left inclined groove 3231 is inclined to the left, and the right inclined groove 3231 is inclined to the right. The specific inclination angles of the two can be different or the same, as long as the guide rod 3241 can swing back and forth when moving between the two. The working principle of the above technical solution is: the drive motor 31 drives the screw rod 321 to rotate, and when the screw rod 321 rotates, it will drive the nut 322 and the mounting frame 324 to move up and down. Since the guide rod 3241 passes through the guide groove 3231, when the mounting frame 324 moves up and down, it will drive the mounting frame 324 to swing left and right, so that the nozzle 331 can swing left and right to perform a wider range of cleaning. The above solution still only needs one driving source to realize the up and down movement and left and right swing of the water spray assembly 33, and the driving source can be set above the mounting partition 2, and is not affected by the sewage and water vapor in the lower water storage chamber 12.

[0036] Specifically, there are multiple nozzles 331, and the multiple nozzles 331 are arranged in an array in the vertical direction and the horizontal direction. The solution can increase the water spray cleaning area and the cleaning effect.

[0037] Specifically, a water pump and a switching valve are provided in the lower water storage chamber 12, the water pump is connected to the water inlet of the switching valve through a pipeline, one of the outlets of the switching valve is connected to the water outlet pipe 5 through a pipeline, the other outlet of the switching valve is connected to the nozzle 331 through a pipeline, a filter is provided between the switching valve and the nozzle 331, and the switching valve and the filter are both installed in the upper electrical installation chamber 11. The solution can use the water pump to supply water to the water spray assembly 33.

[0038] Embodiment 2:

[0039] like Figures 2 to 6 As shown, on the basis of Example 1, the mounting frame 324 includes a fixed plate 3242 and a movable plate 3243, the nozzle 331 is hinged to the fixed plate 3242, the guide rod 3241 is slidably connected to the fixed plate 3242 in the vertical direction, one end of the guide rod 3241 is fixed to the movable plate 3243, the other end of the guide rod 3241 passes through the fixed plate 3242 and is connected to the nozzle 331, so that the guide rod 3241 drives the nozzle 331 to swing up and down, the diameter of the corresponding position of the guide rod 3241 and the guide groove 3231 is smaller than the width of the guide groove 3231, so that the guide rod 3241 has a vertical movable space in the guide groove 3231, and a guide piece 3246 adapted to the guide groove 3231 is fixed on the fixed plate 3242, so that the fixed plate 3242 can slide along the guide groove 3231.

[0040] In the above technical solution, the adaptation of the guide member 3246 to the guide groove 3231 means that the width of the guide member 3246 is the same as the width of the guide groove 3231. Since the diameter of the corresponding position of the guide rod 3241 and the guide groove 3231 is smaller than the width of the guide groove 3231 (the width mentioned here refers to the dimension in the vertical direction), when the screw rod 321 drives the nut 322 to move downward, the movable plate 3243 drives the guide rod 3241 to move downward. Since the fixed plate 3242 is provided with a guide member 3246 adapted to the guide groove 3231, the fixed plate 3242 is fixed at this time, and the guide rod 3241 drives the nozzle 331 to swing downward or upward, thereby changing the up and down direction of the nozzle 331. After the guide rod 3241 moves to the lower limit position, it can only move obliquely downward along the inclination direction of the guide groove 3231. At this time, the nut 322 drives the movable plate 3243 and the guide rod 3241 to move downward. 241, the fixed plate 3242 and the nozzle 331 move obliquely downward together for water spray cleaning; when the screw rod 321 drives the nut 322 to move upward, the movable plate 3243 drives the guide rod 3241 to move upward. Since the fixed plate 3242 is provided with a guide piece 3246 adapted to the guide groove 3231, the fixed plate 3242 is fixed at this time, and the guide rod 3241 drives the nozzle 331 to swing upward or downward, thereby changing the up and down direction of the nozzle 331. When the guide rod 3241 moves to the upper limit position, it can only move obliquely upward along the inclination direction of the guide groove 3231. At this time, the nut 322 drives the movable plate 3243, the guide rod 3241, the fixed plate 3242 and the nozzle 331 to move obliquely upward together for water spray cleaning. The above technical solution can make the nozzle 331 have different orientations during the upward and downward movement of the mounting frame 324, thereby increasing the vertical cleaning range of the nozzle 331, shortening the lifting height of the lifting mechanism 32, reducing costs, and making the lower end of the lifting mechanism 32 away from the sewage at the bottom. The above solution still only needs one driving source to realize the up and down movement, left and right swing of the water spray assembly 33 and the up and down swing of the nozzle 331, and the driving source can be set above the mounting partition 2, and is not affected by the sewage and water vapor in the lower water storage chamber 12.

[0041] In this solution, the lower end of the self-cleaning device 3 can be suspended, and the lower end of the lifting mechanism 32 can be fixed to the mounting partition 2 through a fixing structure. It can be understood that in another embodiment, the lower end of the lifting mechanism 32 can also be fixed to the bottom of the lower water storage chamber 12.

[0042] Specifically, a horizontal groove 332 extending in the horizontal direction is provided on the nozzle 331 , a connecting rod 3244 is fixed to one end of the guide rod 3241 away from the movable plate 3243 , and one end of the connecting rod 3244 extends into the horizontal groove 332 and can slide relative to the horizontal groove 332 .

[0043] Preferably, the number of the guide plates 323 is two, and the two guide plates 323 are arranged on opposite sides of the screw rod 321, and the two guide plates 323 are connected to corresponding guide rods 3241; the number of the guide rods 3241 is multiple, and the multiple guide rods 3241 arranged on the same guide plate 323 are arranged at intervals along the vertical direction. The above technical solution can make the guide structure more stable.

[0044] Preferably, a rotating wheel is sleeved at the position corresponding to the guide rod 3241 and the guide groove 3231, and the rotating wheel is rotatably connected to the guide rod 3241. The solution can reduce the wear between the guide rod 3241 and the guide groove 3231. Similarly, the guide member on the fixing plate 3242 and the guide groove 3231 can also be in contact through the rotating wheel.

[0045] In the above technical solution, the connection between the guide rod 3241 and the nozzle 331 can be achieved, so that the up and down movement of the guide rod 3241 can drive the nozzle 331 to swing up and down.

[0046] Preferably, the guide plate 323 is an arc-shaped plate, and the axis of the arc-shaped plate coincides with the axial direction of the screw rod 321; the diameter passing through the axis of the arc-shaped plate is the first diameter, and in the upper side wall of the left inclined groove 3231, the heights of the side wall positions passing through the same first diameter are the same; in the lower side wall of the left inclined groove 3231, the heights of the side wall positions passing through the same first diameter are the same; in the upper side wall of the right inclined groove 3231, the heights of the side wall positions passing through the same first diameter are the same; in the lower side wall of the right inclined groove 3231, the heights of the side wall positions passing through the same first diameter are the same.

[0047] In the above technical solution, the arc plate can better adapt to the mounting frame 324 and better guide the mounting frame 324. The side walls passing through the same first diameter have the same height to ensure that in the extension direction of the guide rod 3241, the side walls of the right bevel groove 3231 or the left bevel groove 3231 have the same height, so that the guide rod 3241 contacts more side walls, the contact surface is larger, and it is less prone to wear.

[0048] It can be understood that in one embodiment, the hinge point between the nozzle 331 and the fixed plate 3242 is the first position, the water outlet of the nozzle 331 is the second position, and the connecting rod 3244 is arranged between the first position and the second position, so that the moving direction of the connecting rod 3244 relative to the fixed plate 3242 is consistent with the swinging direction of the nozzle 331 relative to the fixed plate 3242. In the above technical solution, the swinging direction is consistent means that when the connecting rod 3244 moves upward relative to the fixed plate 3242, the nozzle 331 swings upward relative to the fixed plate 3242. Since the moving direction of the connecting rod 3244 relative to the fixed plate 3242 is consistent with the swinging direction of the nozzle 331 relative to the fixed plate 3242, the nozzle 331 can be directed obliquely upward when the mounting frame 324 moves from bottom to top, and the nozzle 331 can be directed obliquely downward when the mounting frame 324 moves from top to bottom. The water flow direction is inclined toward the inner wall, and the water flow is sprayed from the cleaned side to the uncleaned side, so as to better clean the bottom of the area to be cleaned.

[0049] It can be understood that in another embodiment, the first position is set between the connecting rod 3244 and the second position, so that the moving direction of the connecting rod 3244 relative to the fixed plate 3242 is opposite to the swinging direction of the nozzle 331 relative to the fixed plate 3242. In the above technical solution, the opposite swinging direction means that when the connecting rod 3244 moves upward relative to the fixed plate 3242, the nozzle 331 swings downward relative to the fixed plate 3242. The above solution can make the water flow direction tilted toward the inner wall, so as to better clean the bottom of the area to be cleaned.

The mounting frame 324 includes a first part and a second part fixed to each other, the first part is fixed to the nut 322, and the nozzle 331 is fixed to the second part.
