Description

Technical Field

[0001] The present invention relates to the field of irrigation technology, and in particular to an assembled single well pump station and a control method thereof. Background Art

[0002] At present, the traditional pump station used in agricultural irrigation needs to cut off the water flow at the water diversion point for the construction and installation of the pump station, and then guide the water flow after the installation is completed. This type of pump station installation has the disadvantages of high cost, large investment, long construction time, and large area of ​​farmland occupied. Therefore, in the past two years, prefabricated pump stations have gradually begun to develop, such as the prefabricated wellbore pump station disclosed in CN208857883U.

[0003] Although the prefabricated pump stations publicly available on the market have the advantages of low cost, less investment, shorter construction time, and smaller area of ​​farmland occupied, most of them are located underwater. After long-term use, some aquatic plants will be entangled on the trash racks and some larger debris will accumulate, affecting the normal water intake of the pump stations. In addition, since they are located under the water surface, it is difficult to clean the pollution. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the assembled single-well pump station and the control method thereof provided by the present invention can clean the pollution interception mechanism before irrigation.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0006] In a first aspect, an assembled single-well pump station is provided, comprising a pump chamber and a water pump for pumping water out of the pump chamber, a water inlet for water flow entering is provided on the side wall of the pump chamber, and the water inlet is covered with a dirt intercepting mechanism; and a dirt cleaning mechanism is embedded in the dirt intercepting mechanism and is used for reciprocating up and down motion to clean the dirt intercepting mechanism.

[0007] The beneficial effects of the present invention are as follows: the garbage intercepting mechanism of the present scheme can intercept aquatic plants and larger debris near the water inlet. After the pump station is started, the up and down movement of the garbage cleaning mechanism can peel off the aquatic plants and larger garbage on the garbage intercepting mechanism, and press the aquatic plants into the soil or bring them into the water, floating on the water surface, thereby ensuring the normal operation of the water pump; furthermore, the up and down movement of the garbage cleaning mechanism can also move some of the deposited garbage near the water inlet, so that part of the garbage floats out of the water surface, thereby avoiding the water taken out containing a large amount of garbage that pollutes farmland.

[0008] Furthermore, the dirt cleaning mechanism includes a dirt cleaning body and a plurality of dirt cleaning teeth distributed on the dirt cleaning body and embedded in the dirt blocking mechanism;

[0009] Alternatively, the dirt cleaning mechanism comprises a dirt cleaning body and dirt cleaning teeth mounted on each dirt blocking rod of the dirt blocking mechanism, and the dirt cleaning teeth are connected to the dirt cleaning body;

[0010] Alternatively, the cleaning mechanism comprises a cleaning body and a plurality of cleaning steel brushes connected to the cleaning body.

[0011] The beneficial effects of the above technical solution are: the above-mentioned various structural forms of the cleaning mechanism can efficiently clean the aquatic plants and larger garbage on the garbage blocking mechanism; the cleaning steel brush and the cleaning teeth mounted on the garbage blocking rod can also clean the sludge attached to the garbage blocking mechanism.

[0012] Furthermore, the assembled single wellbore pump station also includes a gate for closing the water inlet, and the gate is raised or lowered by the gate power mechanism;

[0013] Alternatively, the gate is raised and lowered by the cleaning mechanism, and a gate locking mechanism is also included in this case, which is used to limit the gate from descending when the cleaning mechanism raises the gate to a preset position.

[0014] The beneficial effects of the above technical scheme are as follows: the gate provided in this scheme is mainly used to protect the pump room, to prevent a large amount of debris from entering the pump room when it is not used for a long time, affecting the normal water diversion after the pump station is started; at the same time, it can also prevent debris from entering the farmland with the diverted water and polluting the farmland.

[0015] Both gate opening methods can ensure the rapid start-up of the gate. When two sets of power mechanisms are used, the gate and the cleaning mechanism can be controlled separately, making the opening more flexible. When one set of power mechanism is used in conjunction with the gate locking mechanism to achieve gate opening, the mutual influence between the cleaning mechanism and the gate can be avoided during movement, thereby reducing costs.

[0016] Further, when the gate is arranged on the inner side of the dirt blocking mechanism, the dirt cleaning teeth located on the inner side of the dirt blocking mechanism are used to carry the gate;

[0017] When the gate is arranged outside the dirt blocking mechanism, the dirt cleaning teeth / the dirt cleaning steel brushes located outside the dirt blocking mechanism are used to support the gate.

[0018] The beneficial effects of the above technical solution are: when the gate is located on the inner side of the pollution blocking mechanism and is not used for a long time, the pollution blocking mechanism can block aquatic plants and larger debris. When the pump station is started, it can be quickly cleaned by the pollution cleaning mechanism. At this time, the pollution blocking mechanism can play a certain guiding and limiting role on the gate.

[0019] When the gate is located outside the pollution blocking mechanism, the gate can block aquatic plants and larger debris. When the gate is opened, the pollution cleaning mechanism can clean up the debris that escapes and enters the pollution blocking mechanism when the gate is opened.

[0020] Further, the trash blocking mechanism includes a square frame and a trash blocking rod longitudinally arranged on the square frame;

[0021] Alternatively, the dirt-blocking mechanism is a grid screen, and the grid screen cooperates with a dirt-cleaning steel brush.

[0022] The beneficial effects of the above technical solution are as follows: the above first type of trash interceptor can intercept aquatic plants and larger debris, and is mainly used in scenes where there are many plants in deep rivers and few small debris in the water intake environment.

[0023] The second type of pollution interception mechanism can intercept both large and small debris, and has lower requirements on water quality in the water intake scene. It can also reduce the possibility of garbage pollution in farmland water.

[0024] Furthermore, the mechanism for driving the cleaning mechanism to move up and down and the gate power mechanism are hydraulic lifting mechanism, electric lifting mechanism or screw nut transmission mechanism;

[0025] The hydraulic lifting mechanism includes a hydraulic cylinder and a lifting connector connected to the hydraulic cylinder, and the lifting connector is fixedly connected to the cleaning mechanism;

[0026] The electric lifting mechanism is an electric push rod, and the telescopic end of the electric push rod is fixedly connected to the cleaning mechanism;

[0027] The screw rod and nut transmission mechanism comprises a motor, a screw rod fixedly connected to the output end of the motor, and a nut installed on the cleaning mechanism and matched with the screw rod.

[0028] The beneficial effect of the above technical solution is that the lifting mechanisms of the above various structures can realize the opening of the cleaning mechanism and the gate, and can be flexibly selected according to the usage scenario.

[0029] Furthermore, the gate locking mechanism includes a limiting hole provided on the gate and a telescopic mechanism extending out of / out of the limiting hole to limit / release the gate;

[0030] Or the gate locking mechanism includes a gate sling fixed to the top of the gate, and a limit hole is provided on the gate sling. The limit hole cooperates with a telescopic mechanism that extends out of / out of the limit hole to limit / release the gate.

[0031] The beneficial effect of the above technical solution is that the gate stays at the preset position and can be extended by the telescopic mechanism to extend into the limiting hole to limit the gate to ensure stable parking of the gate.

[0032] Furthermore, the assembled single-well pump station also includes a trash retaining wall, which includes a first trash retaining plate installed on the pump chamber side walls on both sides of the water inlet and / or a second trash retaining plate installed on the pump chamber side walls at the top of the water inlet of the trash retaining wall.

[0033] The beneficial effects of the above technical solution are: the first trash retaining plate can prevent silt from accumulating at the water inlet; when the water pump is working, the second trash retaining plate can prevent smaller debris floating above the water inlet from entering through the water inlet and being pumped into the farmland, polluting the farmland.

[0034] Furthermore, the assembled single-well pump station also includes a control cabinet and a detection sensor for detecting when the gate rises to a preset position. The control cabinet is respectively connected to the mechanism that drives the cleaning mechanism to move up and down, the gate power mechanism, the gate locking mechanism and the detection sensor.

[0035] The beneficial effect of the above technical solution is that after the control cabinet is introduced, the automatic coordination of various electrical components of the pump station can be achieved, thereby improving the automation of the pump station operation.

[0036] Furthermore, the assembled single-well pump station also includes a maintenance bridge connected to one side above the pump room, and the maintenance bridge is used to connect the land and the pump room.

[0037] The beneficial effects of the above technical solution are: the inspection bridge not only serves as an inspection passage, but also as a fixed connection part of the pump room. The pump room can be fixed by the inspection bridge to prevent it from moving, thereby avoiding a large amount of civil engineering fixation of the pump room, further shortening the construction period and saving investment.

[0038] In a second aspect, a control method for an assembled single wellbore pump station is provided, comprising the steps of:

[0039] S1, receiving the pump station start signal, opening the gate and limiting the gate at the preset position;

[0040] S2. When cleaning is required, the cleaning mechanism is started to move up and down to clean the dirt, and the water pump is started for irrigation;

[0041] S3. When receiving the pump station shutdown signal, close the water pump and the gate.

[0042] The beneficial effect of the above technical solution is that by setting up a cleaning mechanism, the solution can perform cleaning operations before the water pump is started, thereby reducing the impact of aquatic plants and debris attached to the water inlet on the operation of the pump station.

[0043] Furthermore, the control method of the assembled single wellbore pump station also includes:

[0044] Collect image information at the water inlet or resistance information of the gate opening, and when the image information or resistance information indicates that the pollution blocking mechanism needs to be cleaned, start the pollution cleaning mechanism to move up and down for a first preset cleaning time;

[0045] When the image information or the resistance information indicates that the dirt blocking mechanism does not need to be cleaned, the dirt cleaning mechanism is not activated or is activated to clean the dirt for a second preset time period;

[0046] The first preset duration is greater than the second preset duration.

[0047] The beneficial effect of the above technical scheme is: by judging the situation of debris near the water inlet, it is possible to accurately judge whether there are aquatic plants and debris near the water inlet, so as to avoid long-term cleaning when there is no debris, which results in energy waste.

[0061] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0062] Example 1

[0063] like Figure 1 and Figure 4 As shown, the assembled single-well pump station provided by the present solution includes a pump chamber 1 and a water pump 3 for pumping water out of the pump chamber 1. The top of the pump chamber 1 forms an operating platform, and some electrical components can be placed on the operating platform; wherein the pump chamber 1 can be configured as a square body, a cylinder or a prism. From the perspective of ease of installation and transportation, the pump chamber 1 is preferably configured as a cylinder.

[0064] The water pump 3 can be a submersible pump 3, an axial flow pump or other common water pumps 3. When the submersible pump 3 is selected, no additional structure is required inside the pump chamber 1. The water pump 3 is directly placed at the bottom of the pump chamber 1, and the water outlet end of the water pump 3 is connected to the outlet pipe 2. The schematic diagram of the pump station using the submersible pump 3 can be referred to Figure 4 and Figure 5 .

[0065] When the water pump 3 is a non-submersible pump 3, it is necessary to reserve space for the installation of the water pump 3 on the operating platform at the top of the pump chamber 1 or in a place where the upper end of the pump chamber 1 will not be flooded. For details, please refer to Figure 1 and Figure 3 .

[0066] Reference again Figure 1 and Figure 4 A water inlet 12 for water flow to enter is provided on the side wall of the pump chamber 1, and the water inlet 12 is covered with a dirt blocking mechanism 4; the pump station also includes a dirt cleaning mechanism 7 embedded in the dirt blocking mechanism 4 and used for reciprocating up and down to clean the dirt blocking mechanism 4.

[0067] After the cleaning mechanism 7 is provided in this scheme, the cleaning mechanism 7 can be used to regularly clean the dirt blocking mechanism 4, and there is no need to manually remove aquatic plants and larger debris near the water inlet 12 before each start, thereby reducing the cleaning intensity and ensuring the normal operation of the pump chamber 1.

[0068] During implementation, the assembled single-well pump station of this embodiment further includes an inspection bridge 10 connected to one side above the pump chamber 1, and the inspection bridge 10 is used to connect the land and the pump chamber 1. The inspection bridge 10 not only serves as an inspection channel, but also as a fixed connection part of the pump chamber 1. The pump chamber 1 is fixed by the inspection bridge 10 to prevent it from moving, thereby avoiding a large amount of civil engineering fixing of the pump chamber 1, further shortening the construction period and saving investment.

[0069] Example 2

[0070] This embodiment is a further improvement of the cleaning mechanism 7 based on the embodiment 1. In this embodiment, three implementation methods of the cleaning mechanism 7 are provided. However, when implementing the cleaning, this solution is not limited to these three implementation methods. The three implementation methods of this solution are:

[0071] The first implementation method of the cleaning mechanism 7 can be referred to Figure 8 It includes a cleaning body 71 and a plurality of cleaning teeth (the cleaning teeth can be made of steel plates) 72 distributed on the cleaning body 71 and embedded in the dirt blocking mechanism 4; when the cleaning teeth 72 move quickly, they can cut off the aquatic plants and larger debris entangled on the dirt blocking mechanism 4, and the debris that cannot be cut off can be pressed into the soil or into the water under the force of the rapid movement, and float to the water surface, so as to solve the problem of the aquatic plants and larger debris affecting the water intake of the water pump 3.

[0072] The second implementation scheme of the cleaning mechanism 7 can be referred to Fig. 9 , which includes a cleaning body 71 and cleaning teeth 72 mounted on each dirt blocking rod 41 of the dirt blocking mechanism 4, and the cleaning teeth 72 are connected to the cleaning body 71; this implementation method is generally the same in structure as the first implementation method, except that an annular body is provided on each cleaning tooth 72, and the cleaning tooth 72 can be mounted on the dirt blocking rod 41 through the annular body. In this way, this implementation method not only has the advantages of the first implementation method, but also can clean the sludge on the dirt blocking rod 41.

[0073] The third implementation scheme of the pollution removal mechanism 7 can be referred to Fig.10 It includes a cleaning body 71 and a plurality of cleaning steel brushes 73 connected to the cleaning body 71. Compared with the cleaning teeth 72, the cleaning steel brushes 73 cannot cut aquatic plants, but can press these debris into the sludge or clean them into the water and float to the water surface. In addition, the cleaning steel brushes 73 can also clean the sludge on the dirt blocking rod 41.

[0074] The structures of the cleaning body 71 of the cleaning mechanism 7 in the three implementation modes of this embodiment can be the same; furthermore, in order to increase the cleaning area of ​​the cleaning teeth 72 or the cleaning steel brush 73, the cleaning teeth 72 and the cleaning steel brush 73 can be set to have an inclined angle with the dirt blocking mechanism 4.

[0075] Example 3

[0076] This embodiment is a further improvement on the basis of Embodiment 1 or Embodiment 2, specifically, the assembled single wellbore pump station further comprises a gate 5 for closing the water inlet 12, and preferably guide grooves for sliding the gate 5 are provided on both sides of the water inlet 12. This embodiment provides two ways of opening the gate 5, wherein the first implementation way is that the gate 5 is raised or lowered by the gate power mechanism, in which the gate 5 and the cleaning mechanism 7 can be controlled separately, and the opening is more flexible.

[0077] Another way to open gate 5 can refer to Figure 8 The gate 5 is lifted and lowered by the cleaning mechanism 7. Specifically, the gate 5 is placed on the cleaning teeth 72 / cleaning steel brushes 73. At this time, the gate locking mechanism 8 is also included, which is used to limit the gate 5 from falling when the cleaning mechanism 7 lifts the gate 5 to a preset position. The specific implementation process of this method is as follows:

[0078] The mechanism 6 that drives the cleaning mechanism 7 to move up and down is started. When the cleaning mechanism 7 moves upward, the gate 5 placed on the cleaning teeth 72 / cleaning steel brush 73 moves upward. After moving to the preset position, the gate locking mechanism 8 is started. The gate locking mechanism 8 limits the gate 5 so that the gate 5 can stay stably in the preset position. Then, the cleaning mechanism 7 is moved up and down by the mechanism 6 that drives the cleaning mechanism 7 to move up and down, thereby cleaning the dirt of the dirt blocking mechanism 4.

[0079] The second implementation method of opening the gate 5 only requires a set of power mechanisms extending into the water to realize the opening of the two components, which can reduce costs.

[0080] There are also two ways of installing the gate 5 introduced in this embodiment, that is, the gate 5 is arranged on the inner side or the outer side of the dirt blocking mechanism 4; when the gate 5 is located on the inner side, the dirt cleaning mechanism 7 can guide and limit the movement of the gate 5 to prevent the gate 5 from shaking when it rises.

[0081] In this embodiment, when the gate 5 is arranged on the inner side of the dirt blocking mechanism 4 , the dirt cleaning teeth 72 located on the inner side of the dirt blocking mechanism 4 are used to support the gate 5 ; when the gate 5 is arranged on the outer side of the dirt blocking mechanism 4 , the dirt cleaning teeth 72 / dirt cleaning steel brush 73 located on the outer side of the dirt blocking mechanism 4 are used to support the gate 5 .

[0082] When the gate 5 is located inside the pollution blocking mechanism 4, the pollution blocking mechanism 4 can block aquatic plants and larger debris. When cleaning pollution, the aquatic plants need to be cut off. At this time, it cooperates with the pollution cleaning teeth 72, and its pollution cleaning effect is better than that of the pollution cleaning steel brush 73.

[0083] When the gate 5 is located outside the pollution blocking mechanism 4, the gate 5 can block aquatic plants and larger debris. After the gate 5 is opened, some aquatic plants that have detached from the gate 5 gather at the pollution blocking mechanism 4. The aquatic plants will not be entangled on the pollution blocking mechanism 4 and are relatively easy to clean. At this time, the cleaning teeth 72 can be used for cleaning. Therefore, in this case, the cleaning teeth 72 / cleaning steel brush 73 can be used.

[0084] Example 4

[0085] This embodiment is a further improvement on any one of the embodiments 1-3, and provides two implementations of the dirt trapping mechanism 4, wherein the first implementation can be referred to in Figure 1 and Figure 4 It includes a square frame and dirt-blocking bars 41 longitudinally arranged on the square frame. There is a certain distance between adjacent dirt-blocking bars 41. The dirt-cleaning teeth 72 or the dirt-cleaning steel brushes 73 of the three types of dirt-cleaning mechanisms 7 in Example 2 extend to between adjacent dirt-blocking bars 41 for cleaning, so as to quickly clean the aquatic plants or debris entangled on the dirt-blocking mechanism 4.

[0086] The second implementation method of the dirt trap mechanism 4 can be referred to Fig.11 , which is configured as a grid mesh plate, and the grid mesh plate cooperates with a cleaning steel brush 73. When the gate 5 is arranged outside the dirt blocking mechanism 4 of this implementation, in order to ensure efficient cleaning of debris outside the grid mesh plate, the cleaning mechanism 7 is preferably arranged outside the dirt blocking mechanism 4.

[0087] The first embodiment of the dirt-blocking mechanism 4 has a dirt-cleaning effect that is not affected regardless of whether the gate 5 and the dirt-cleaning mechanism 7 are arranged on the inside or outside thereof. The second embodiment of the dirt-blocking mechanism 4 has a higher requirement for the installation position of each component during use, but has a better dirt-blocking effect, which can prevent smaller debris from entering the pump chamber 1, thereby reducing the possibility of farmland being polluted by debris.

[0088] Example 5

[0089] The present embodiment is a further improvement on the basis of any one of the embodiments 1-4, and specifically includes three implementation methods for the mechanism 6 that drives the cleaning mechanism 7 to move up and down and the power mechanism of the gate 5, namely a hydraulic lifting mechanism, an electric lifting mechanism or a screw nut transmission mechanism, all of which are installed on the top of the pump chamber 1 to form an operating platform, and the execution end extends into the water to connect with the cleaning body 71.

[0090] like Figure 2 and Figure 6 As shown, the hydraulic lifting mechanism includes a hydraulic cylinder 61 and a lifting connection member 62 connected to the hydraulic cylinder 61 , and the lifting connection member 62 is fixedly connected to the cleaning mechanism 7 ; specifically, the lifting connection member 62 is connected to the cleaning body 71 of the cleaning mechanism 7 .

[0091] The electric lifting mechanism is an electric push rod, the telescopic end of which is fixedly connected to the cleaning body 71 of the cleaning mechanism 7; when the electric push rod is in use, the part of the structure extending into the water needs to be waterproofed to ensure the normal operation of the electrical components.

[0092] The screw-nut transmission mechanism includes a motor, a screw fixedly connected to the output end of the motor, and a nut mounted on the cleaning mechanism 7 and cooperating with the screw; in order to prevent the cleaning mechanism 7 from slipping off the screw, a limit block can be set at the end of the screw.

[0093] The electric lifting mechanism and the screw-nut transmission mechanism mentioned in this embodiment are both relatively conventional power components in the prior art, so no corresponding illustrations are given.

[0094] Example 6

[0095] This embodiment is a further improvement on the embodiment with the gate 5 . Specifically, the gate locking mechanism 8 includes a limiting hole 83 provided on the gate 5 and a telescopic mechanism 82 extending out of / out of the limiting hole 83 to limit / release the gate 5 .

[0096] Alternatively, the gate locking mechanism 8 includes a gate sling 81 fixed to the top of the gate 5 , a limiting hole 83 is provided on the gate sling 81 , and the limiting hole 83 cooperates with a telescopic mechanism 82 that extends out of / out of the limiting hole 83 to limit / release the gate 5 .

[0097] The telescopic mechanisms 82 of the two implementations of the gate locking mechanism 8 can have the same structure as the hydraulic lifting mechanism and the electric lifting mechanism in Example 5.

[0098] When the gate locking mechanism 8 adopts the first implementation method, if the gate 5 moves to the highest point but still does not reach the top of the pump chamber 1 to form an operating platform, the gate locking mechanism 8 can be set on the wall of the pump chamber 1 and waterproof it.

[0099] When the gate locking mechanism 8 adopts the second implementation method, the gate locking mechanism 8 can be set on the operating platform formed on the top of the pump chamber 1, and the length of the gate sling 81 can be selected according to the height of the pump chamber 1 to ensure the accurate fit between the gate locking mechanism 8 and the limiting hole 83.

[0100] Example 7

[0101] This embodiment is an improvement on the assembled single wellbore pump station based on any one of 1-6. Fig.12 As shown, the pump station further includes a trash retaining wall 9, which includes a first trash retaining plate 91 installed on the side walls of the pump chamber 1 on both sides of the water inlet 12 and / or a second trash retaining plate 92 installed on the side wall of the pump chamber 1 at the top of the water inlet 12.

[0102] The first trash retaining plate 91 can prevent silt from accumulating at the water inlet 12; when the water pump 3 is working, the second trash retaining plate 92 can block the debris floating above the water inlet 12, preventing smaller debris floating above the water inlet 12 from entering through the water inlet 12 under the suction of the water pump 3, being pumped into the farmland, and polluting the farmland.

[0103] Example 8

[0104] The present embodiment is an improvement made on the basis of an assembled single-well pump station having a gate 5, and the cleaning mechanism 7 and the gate 5 rise and fall using the same power mechanism. Specifically, the assembled single-well pump station also includes a control cabinet 11 and a detection sensor (the detection sensor can be a photoelectric sensor) for detecting when the gate 5 rises to a preset position. The control cabinet 11 is respectively connected to the mechanism 6 that drives the cleaning mechanism 7 to move up and down, the gate power mechanism, the gate locking mechanism 8 and the detection sensor.

[0105] After the control cabinet 11 is introduced in this embodiment, after the pump station is started, automatic coordination of various electrical components can be achieved, thereby improving the automation of the pump station operation.

[0106] The control cabinet 11 of this embodiment is equipped with an electrical automatic control system to realize intelligent control, such as configuring relevant electrical components such as a PLC controller, and controlling the orderly movement and operation of each component through a PLC programming program. When the system is started, the gate 5 is started by manually operating the PLC controller to clean the dirt retaining mechanism 4, and then the water pump 3 is started to work. After working for a period of time, the water pump 3 is manually turned off.

[0107] In order to realize fully automated control, a mobile terminal can also be included. The PLC controller communicates with the mobile terminal through a wireless communication module, and the management personnel can realize remote control through the mobile terminal. The start-up sequence of each execution component and the duration of each work can also be preset to achieve fully automated execution after one-click start.

[0108] Example 9

[0109] The assembled single-well pump station of this embodiment includes a pump chamber 1, a sewage cleaning mechanism 7 and a water pump 3 for discharging water from the pump chamber 1. A water inlet 12 for water flow to enter is provided on the side wall of the pump chamber 1, and the water inlet 12 is covered with a sewage blocking mechanism 4; the sewage cleaning mechanism 7 is embedded in the sewage blocking mechanism 4 and is used for reciprocating up and down to clean the sewage blocking mechanism 4; a gate 5 for closing the water inlet 12 is slidably connected to the water inlet 12.

[0110] The cleaning mechanism 7 includes a cleaning body 71 and a plurality of cleaning teeth 72 distributed on the cleaning body 71 and embedded in the blocking mechanism 4; the gate 5 is raised and lowered by the cleaning mechanism 7, and at this time, it also includes a gate locking mechanism 8, which is used to limit the gate 5 from descending when the cleaning mechanism 7 raises the gate 5 to a preset position.

[0111] The mechanism 6 that drives the cleaning mechanism 7 to move up and down is a hydraulic lifting mechanism, specifically including a hydraulic cylinder 61 and a lifting connector 62 connected to the hydraulic cylinder 61, and the lifting connector 62 is fixedly connected to the cleaning mechanism 7; the gate locking mechanism 8 includes a gate sling 81 fixed to the top of the gate 5, and a limiting hole 83 is provided on the gate sling 81, and the limiting hole 83 cooperates with a telescopic mechanism 82 that extends / disengages from the limiting hole 83 to limit / release the gate 5.

[0112] The working principle of the assembled single well pump station is as follows: the hydraulic cylinder 61 drives the cleaning mechanism 7 to drag the gate 5 upward through the lifting connection 62. When the detection sensor detects that the gate 5 reaches the preset position, the gate locking mechanism 8 is activated, and the telescopic mechanism 82 is inserted into the limit hole 83. The gate 5 is stabilized at this height through the gate sling 81;

[0113] After the gate 5 is fixed, the cleaning mechanism 7 can be driven by the hydraulic cylinder 61 to reciprocate and perform cleaning operations. After the cleaning is completed, the water pump 3 is started to divert water. After the diversion is completed, the water pump 3 is turned off, and the hydraulic cylinder 61 drives the cleaning mechanism 7 to move to the bottom of the gate 5, and the telescopic mechanism 82 retracts to release the limit on the gate 5. The gate 5 is located on the cleaning teeth 72, and then under the action of the hydraulic cylinder 61, the gate 5 and the cleaning mechanism 7 are returned to their original positions.

[0114] Example 10

[0115] The present invention also provides a control method for an assembled single wellbore pump station, which comprises the following steps:

[0116] S1, receiving the pump station start signal, opening the gate 5 and limiting the gate 5 to a preset position;

[0117] S2, when it is necessary to clean the dirt, start the cleaning mechanism 7 to move up and down to clean the dirt, and start the water pump 3 to irrigate;

[0118] S3. When the pump station shutdown signal is received, the water pump 3 and the gate 5 are closed.

[0119] In order to achieve accurate pollution removal, the control method of the assembled single well pump station can also include:

[0120] Collect image information at the water inlet 12 or resistance information of the gate 5 when it is opened. When the image information or resistance information indicates that the pollution blocking mechanism 4 needs to be cleaned (for example, the resistance is greater than a preset threshold, and the image information shows that there are more weeds), start the pollution cleaning mechanism 7 to move up and down for a first preset cleaning time.

[0121] When the image information or the resistance information indicates that the dirt blocking mechanism 4 does not need to be cleaned, the dirt cleaning mechanism 7 is not started or the dirt cleaning mechanism 7 is started for a second preset time, and then the water pump 3 is started;

[0122] The first preset duration is greater than the second preset duration.

[0123] In summary, the assembled single-well pump station and control method thereof provided in this solution can clean up the debris (aquatic plants, larger debris, etc.) on the dirt-blocking mechanism 4 to ensure normal water intake of the pump station.
