Description

[0002] In order to detect the cathodic protection status of the pipeline, several test piles can be set up along the pipeline. The measuring terminal in the test pile is electrically connected to the pipeline and the reference electrode and test piece buried around the pipeline, and controls the on-off connection between the test piece and the pipeline, so as to measure the parameters such as the power-on potential and power-off potential of the pipeline, and upload them to the remote terminal through the communication module. However, the pipeline is usually located in remote areas, and the measuring terminal in the test pile is an electrical device. The cost of powering the equipment through cables is too high, and new energy power supply is a better power supply method.

[0003] In the new energy power supply device, there are many possible sources of power for the power generation equipment, for example, it can be a solar power generation unit and a wind power generation unit. However, these power generation methods are greatly affected by the natural environment, so the test pile is also equipped with a battery to store electrical energy. When both sunlight and wind power are insufficient, in order to ensure that the measurement terminal is not disconnected from power, it is necessary to use a battery to power the measurement terminal; when at least one of the sunlight and wind power is sufficient, wind power and / or solar power generation will power the measurement terminal and charge the battery.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0061] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0063] Now combined Figure 1 to Figure 2 , various embodiments provided by the present invention are described. It should be understood that the following are merely illustrative embodiments of the present invention and do not constitute any particular limitation to the present invention.

[0064] Figure 1 This is a structural block diagram of the power supply device provided by the present invention, see Figure 1 The embodiment of the present invention provides a power supply device 100 , which includes: a power generation unit 110 , a primary charge and discharge controller 120 , a primary battery 130 , an electric control unit 140 , a secondary charge and discharge controller 150 , and a secondary battery 160 .

[0065] Among them, the power generation unit 110, the primary charge and discharge controller 120, the electric control unit 140, and the secondary charge and discharge controller 150 are electrically connected in sequence. Moreover, the primary battery 130 is electrically connected to the primary charge and discharge controller 120, and the secondary battery 160 is electrically connected to the secondary charge and discharge controller 150. It can be seen that the power generation unit 110 is used to output electric energy. The electric control unit 140 is also electrically connected to the secondary battery 160, and the electric control unit 140 can obtain the potential of the secondary battery 160 and realize disconnection or closing based on the potential.

[0066] The power generation unit 110 is used to generate electricity and supply electric energy to the downstream. The structure and power generation principle of the power generation unit 110 can be various, which are not limited in this embodiment, for example, solar power generation, wind power generation, etc.

[0067] Among them, the charge and discharge controller can supply power to the downstream and charge the battery at the same time when there is power input from the upstream, and switch to the battery to supply power to the downstream when there is no power input from the upstream. In other words, whether the upstream supplies power controls the power supply direction of the charge and discharge controller.

[0068] The functions of the primary charge and discharge controller 120 and the secondary charge and discharge controller 150 are similar. When the power generation unit 110 supplies power, the primary charge and discharge controller 120 controls the power supply to the downstream and the primary battery 130 at the same time. When the power generation unit 110 does not supply power, the primary charge and discharge controller 120 controls the primary battery 130 to supply power to the downstream. When the electronic control unit 140 supplies power, the secondary charge and discharge controller 150 controls the power supply to the downstream and the secondary battery 160 at the same time. When the electronic control unit 140 does not supply power, the secondary charge and discharge controller 150 controls the secondary battery 160 to supply power to the downstream.

[0069] The primary battery 130 and the secondary battery 160 are both used to store electrical energy and can be charged and discharged. Specifically, the secondary battery 160 can be used as a common power source for electrical equipment, and the primary battery 130 can be used as a backup power source. The electrical equipment can be a variety of equipment. The following is an example of a measurement terminal 300, which is a terminal device in the test pile. It detects the cathodic protection status of the pipeline by connecting various sensors and uploads data.

[0070] The electric control unit 140 obtains the potential of the secondary battery 160. When the secondary battery 160 is fully charged, the electric control unit 140 is disconnected and does not supply power to the downstream, so that the secondary battery 160 supplies power to the downstream. When the secondary battery 160 is insufficiently charged, the electric control unit 140 is closed, so that the primary charge and discharge controller 120 can supply power to the downstream and the secondary battery 160 at the same time.

[0071] Specifically, after the primary charge and discharge controller 120 is connected to the secondary charge and discharge controller 150, if the power generation unit 110 generates electricity stably, the electric energy generated by the power generation unit 110 is sent to the secondary charge and discharge controller 150 and the primary battery 130 through the primary charge and discharge controller 120; if the power generation unit 110 cannot generate electricity, the primary charge and discharge controller 120 transmits the electric energy in the primary battery 130 to the secondary charge and discharge controller 150. The electric energy received by the secondary charge and discharge controller 150 is transmitted to the secondary battery 160 and the measurement terminal 300, to supply power to the measurement terminal 300, and to charge the secondary battery 160 at the same time.

[0072] The power supply status of the power supply device 100 may include the following:

[0073] 1. Since the secondary battery 160 can store a certain amount of electrical energy, in use, the secondary battery 160 usually supplies power to the downstream measurement terminal 300. In this working state, the primary battery 130 can be charged by the power generation unit 110 and maintained after being fully charged.

[0074] 2. Only when the secondary battery 160 is exhausted or has little power, the electric control unit 140 is closed to charge the secondary battery 160 through the power generation unit 110 or the primary battery 130 .

[0075] in:

[0076] 2.1. When the power generation unit 110 generates electricity stably, it can stably supply power to the primary battery 130 and the secondary battery 160. In this working state, the primary battery 130 can be charged by the power generation unit 110 and maintained after being fully charged.

[0077] 2.2. When the power generation unit 110 cannot generate power, the primary battery 130 can also stably supply power to the secondary battery 160. In this working state, the primary battery 130 is discharged.

[0078] Therefore, this structure can avoid frequent switching between charging and discharging of the primary battery 130 and the secondary battery 160, thereby extending the life of the battery and reducing maintenance costs.

[0079] The power supply device 100 provided in the embodiment of the present invention, by providing a primary battery 130 and a secondary battery 160, uses the secondary battery 160 as a common power source for the measuring terminal 300, and the primary battery 130 as a backup power source. And by providing an electric control unit 140, it can control the power supply device 100 to switch between multiple working states according to the power of the secondary battery 160. That is to say, when the power of the secondary battery 160 is sufficient, the secondary battery 160 is used to power the measuring terminal 300. When the power of the secondary battery 160 is insufficient, the power generation unit 110 or the primary battery 130 is used to power the measuring terminal 300, and the secondary battery 160 is charged at the same time to ensure the power of the secondary battery 160 as a common power source. This structure can avoid the primary battery 130 and the secondary battery 160 from frequently switching between charging and discharging, prolong the life of the battery, and reduce maintenance costs.

[0080] In one embodiment provided by the present invention, the electric control unit 140 includes: an electric control switch 141, an on-off controller 142, and a voltage comparison subunit 143. The electric control switch 141, the on-off controller 142, the voltage comparison subunit 143, and the secondary battery 160 are electrically connected in sequence, and the on-off controller 142 is used to control the opening or closing of the electric control switch 141.

[0081] In the electric control switch 141, the electric control switch 141 is arranged in the power supply circuit, and the on-off controller 142 and the voltage comparison subunit 143 are arranged in the control circuit. The voltage comparison subunit 143 can output a level signal according to the magnitude relationship between the voltage of the secondary battery 160 and its threshold value, and the threshold value of the voltage comparator is set by selecting the specifications of its internal components, which is not limited in this embodiment.

[0082] The on-off controller 142 can control the on-off of the electric control switch 141 according to the level signal sent by the voltage comparison subunit 143, so that when the power of the secondary battery 160 is sufficient, the electrical connection between the two charge and discharge controllers is disconnected, so that the secondary battery 160 can supply power to the measurement terminal 300 alone; when the power of the secondary battery 160 is low, the electrical connection between the two charge and discharge controllers is connected to charge the secondary battery 160, so that the charge and discharge cycle of the secondary battery 160 is longer and the number of charge and discharge times is reduced. And when the electric control switch 141 is disconnected, if the power generation unit 110 generates electricity steadily, the electric energy of the primary battery 130 will not be consumed, thereby reducing the number of charge and discharge times of the primary battery 130, ensuring the energy storage performance of the battery, avoiding frequent replacement of batteries due to rapid decline in energy storage performance, and reducing the cost of operation and maintenance.

[0083] In a further embodiment provided by the present invention, the above-mentioned electronic control unit 140 includes: the voltage comparison subunit 143 includes a first voltage comparator 1431 and a second voltage comparator 1432; the first voltage comparator 1431 and the second voltage comparator 1432 are connected in parallel so that the first voltage comparator 1431 and the second voltage comparator 1432 can respectively identify and compare the voltage of the secondary battery 160.

[0084] In the process of the upstream supplying power to the secondary battery 160 and the measuring terminal 300, the first voltage comparator 1431 can send a high level signal, that is, a disconnection signal, to the on-off controller 142 when the voltage of the connected secondary battery 160 is higher than the first preset voltage, so that the on-off controller 142 controls the electric control switch 141 to disconnect. The upstream stops charging the secondary battery 160 and switches to using the secondary battery 160 to power the measuring terminal 300, so that the measuring terminal 300 remains powered on.

[0085] As the power of the secondary battery 160 decreases, the second voltage comparator 1432 can send a low level signal, that is, a closing signal, to the on-off controller 142 when the voltage of the connected secondary battery 160 is lower than the second preset voltage, so that the on-off controller 142 controls the electric control switch 141 to close, and connects the primary charge and discharge controller 120 with the secondary charge and discharge controller 150. The upstream starts to charge the secondary battery 160 and power the measurement terminal 300.

[0086] Among them, the first voltage comparator 1431 is a high voltage comparator, and the first preset voltage refers to the high threshold of the first voltage comparator 1431. The second voltage comparator 1432 is a low voltage comparator, and the second preset voltage refers to the low threshold of the second voltage comparator 1432. The second preset voltage is lower than the first preset voltage.

[0087] Furthermore, the first preset voltage of the first voltage comparator 1431 may be the voltage when the battery is fully charged, and the second preset voltage of the second voltage comparator 1432 may be the voltage when a certain percentage of the battery power is consumed.

[0088] In any embodiment provided by the present invention, the capacity of the primary battery 130 is smaller than that of the secondary battery 160. The secondary battery 160 is sufficiently charged, and can supply power for a long time alone, with a longer charge and discharge cycle and fewer charge and discharge times per unit time, thereby preventing the energy storage performance of the secondary battery 160 from rapidly decreasing and extending the replacement cycle.

[0089] The power supply device 100 provided in the embodiment of the present invention, by providing a primary battery 130 and a secondary battery 160, uses the secondary battery 160 as a common power source for the measuring terminal 300, and the primary battery 130 as a backup power source. And by providing an electric control unit 140, it can control the power supply device 100 to switch between multiple working states according to the power of the secondary battery 160. That is to say, when the power of the secondary battery 160 is sufficient, the secondary battery 160 is used to power the measuring terminal 300. When the power of the secondary battery 160 is insufficient, the power generation unit 110 or the primary battery 130 is used to power the measuring terminal 300, and the secondary battery 160 is charged at the same time to ensure the power of the secondary battery 160 as a common power source. This structure can avoid the primary battery 130 and the secondary battery 160 from frequently switching between charging and discharging, prolong the life of the battery, and reduce maintenance costs.

[0090] Furthermore, the above-mentioned electric control unit 140 includes: an electric control switch 141, an on-off controller 142 and a voltage comparison subunit 143. The on-off controller 142 can control the on-off of the electric control switch 141 according to the level signal sent by the voltage comparison subunit 143, so that when the power of the secondary battery 160 is sufficient, the electrical connection between the two charge and discharge controllers is disconnected, so that the secondary battery 160 can supply power to the measurement terminal 300 alone; when the power of the secondary battery 160 is low, the electrical connection between the two charge and discharge controllers is connected to charge the secondary battery 160, so that the charge and discharge cycle of the secondary battery 160 is longer and the number of charge and discharge times is reduced. And when the electric control switch 141 is disconnected, if the power generation unit 110 generates electricity steadily, the electric energy of the primary battery 130 will not be consumed, thereby reducing the number of charge and discharge times of the primary battery 130, ensuring the energy storage performance of the battery, avoiding frequent replacement of batteries due to rapid decline in energy storage performance, and reducing the cost of operation and maintenance.

Figure 2 The embodiment of the present invention further provides a new energy test pile 1000, which includes a pile body 200, a measuring terminal 300 and any one of the above-mentioned power supply devices 100. The pile body 200 includes a containing box 210, the measuring terminal 300 is arranged in a containing compartment 211 of the containing box 210, and the secondary charge and discharge controller 150 of the power supply device 100 is electrically connected to the measuring terminal 300, so as to power the measuring terminal 300 through the secondary battery 160, or to make the upstream power the secondary battery 160 and the measuring terminal 300 at the same time.

[0092] The measurement terminal 300 is a terminal device in the test pile, which detects the cathodic protection status of the pipeline by connecting various sensors and uploads data.

[0093] It should be noted that the power generation unit 110 in the power supply device 100 may be disposed on the pile body 200 , and other units in the power supply device 100 may be disposed in the containing compartment 211 .

[0094] In a further embodiment provided by the present invention, the power generation unit 110 includes: a solar power generation sub-unit 111, which can fully utilize solar energy to generate electricity. The solar power generation sub-unit 111 includes: a solar panel, and the solar panel is electrically connected to a primary charge and discharge controller 120.

[0095] Specifically, the pile body 200 further includes a bracket 220, and the solar power generation subunit 111 is rotatably arranged on the top of the bracket 220 to adjust the inclination angle of the solar panel, improve the flexibility of equipment use, and ensure the efficiency of solar power generation.

[0096] In a further embodiment provided by the present invention, the bracket 220 comprises: a frame 221 and an angle adjustment mechanism 222, wherein the frame 221, the angle adjustment mechanism 222 and the solar energy generating electronic unit 111 are sequentially connected. The angle adjustment mechanism 222 comprises: a base 2221 and a rotating base 2222, wherein the base 2221 is connected to the frame 221, the rotating base 2222 is connected to the solar energy generating electronic unit 111, and the base 2221 and the rotating base 2222 are rotatably connected.

[0097] The frame 221 can be a triangular frame with a stable structure to ensure the stability of the solar panel. The base 2221 and the swivel 2222 can be rotatably connected by a hinge. The swivel 2222 is installed on the back of the solar panel, and the base 2221 is installed on the outer end of the frame 221. The base 2221 has a plurality of positioning holes, and the positioning holes are all located on the same arc with the hinge point as the center. The swivel 2222 is plugged with a positioning pin, and the positioning pin is inserted into the positioning hole. By selecting different positioning holes, the angle of the swivel 2222 can be adjusted to achieve the angle adjustment of the solar panel, adapt to the sunlight angle in different regions, and ensure the efficiency of solar power generation.

[0098] In some further embodiments, the outer end of the frame 221 has a mounting flange 223, the mounting flange 223 is connected to the base 2221 by fixing bolts, the mounting flange 223 has a plurality of assembly holes, the assembly holes are evenly distributed on the same circumference, there are a plurality of fixing bolts, and the corresponding assembly holes are respectively penetrated. Since the assembly holes are evenly distributed, the base 2221 can be fixed on the mounting flange 223 at multiple angles, so that the inclination angle of the solar panel in the left and right directions can be adjusted, the flexibility of the equipment is improved, and the efficiency of solar power generation is ensured.

[0099] In a further embodiment provided by the present invention, the power generation unit 110 also includes: a wind power generation sub-unit 112, which is used to supplement the power generation of the solar power generation sub-unit 111, so that solar power generation and wind power generation can be redundant to each other to ensure sufficient power supply.

[0100] Specifically, the pile body 200 further includes a support rod 230 , the wind power generating subunit 112 is disposed at the top end of the support rod 230 , and the bracket 220 is connected to the side of the support rod 230 .

[0101] The wind turbine 113 is a vertical axis wind turbine 113, which is installed at the top of the support rod 230, so as to ensure that it can contact the airflow generated by the wind at multiple angles, thereby ensuring the efficiency of wind power generation. Since the wind direction is mostly in the horizontal direction, the wind power generation sub-unit 112 is set on the top to make full use of wind energy. A bracket 220 is provided on one side of the support rod 230, and the solar panel is installed on the bracket 220, so that the surface of the solar panel can be set at an angle, and can receive sufficient light throughout the day, thereby ensuring the efficiency of solar power generation. Since sunlight is usually at an acute angle to the ground, the solar power generation sub-unit 111 is set on the side to make full use of solar energy.

[0102] The above-mentioned wind power generation subunit 112 includes: a wind turbine 113 and blades 114. The blades 114 are rotatably arranged on the side wall of the wind turbine 113. The wind turbine 113 generates electricity through the rotation of the blades 114. The wind turbine 113 is electrically connected to the first-level charge and discharge controller 120 to supply power thereto.

[0103] In a further embodiment provided by the present invention, the blade 114 includes a connecting rod 115 and a sheet 116. The connecting rod 115 is rotatably connected to the side wall of the wind turbine 113, and the sheet 116 is arranged at the free end of the connecting rod 115. Under the action of wind force, the sheet 116 drives the connecting rod 115 to rotate around the wind turbine 113, thereby driving the wind turbine 113 to generate electricity. Since the sheet 116 has a large force-bearing area, it can generate electricity with a relatively small wind force, thereby improving the power generation efficiency.

[0104] Furthermore, the sheet body 116 includes a first main board 117 and a first side board 118, and the first side board 118 is vertically connected to the edge of the first main board 117 to form a first slot body 119 between the first main board 117 and the first side board 118. The first slot body 119 in this structure is used to accommodate airflow, which can prevent the airflow from flowing through the blades 114, so that the airflow can fully push the blades 114 and ensure the wind power generation effect.

[0105] Furthermore, the first main board 117 has an arc-shaped outer edge and two arc-shaped inner edges, that is, the sheet body 116 is substantially C-shaped. Correspondingly, the first side plate 118 includes a connecting end, an arc-shaped outer side plate and two arc-shaped inner side plates. The connecting end is connected to the connecting rod 115, and each inner side plate is arranged between the connecting end and one end of the outer side plate. This structure can fully utilize wind energy on the basis of saving materials and reducing the weight of the blade 114, and has a high power generation efficiency.

[0106] In any of the above-mentioned embodiments, the connecting rod 115 includes a second main board and a second side board, and the second side board is vertically connected to the two side edges of the second main board to form a second slot body 1151 between the second main board and the second side board. The second slot body 1151 has the same function as the first slot body 119, that is, it is used to accommodate airflow, which can prevent the airflow from flowing through the blades 114, so that the airflow can fully push the blades 114 to ensure the wind power generation effect.

[0107] Moreover, the second slot body 1151 is connected to the first slot body 119 through an inclined surface to form a wind-containing slot 1110, thereby guiding the airflow in the second slot body 1151 to flow smoothly into the first slot body 119, so that the airflow can act on the blades 114 more fully, thereby improving the efficiency of wind power generation.

[0108] Based on the above-mentioned power supply device 100 and the solar power generation sub-unit 111 and the wind power generation sub-unit 112 , the electric energy output by the solar power generation sub-unit 111 and the wind power generation sub-unit 112 may be unstable due to unstable climate environment.

[0109] Specifically, after the primary charge and discharge controller 120 is connected to the secondary charge and discharge controller 150, if the current sunlight or wind power is sufficient, the electric energy generated by the power generation unit 110 through wind power or solar energy is sent to the secondary charge and discharge controller 150 and the primary battery 130 through the primary charge and discharge controller 120; if the current sunlight or wind power is insufficient, the primary charge and discharge controller 120 transmits the electric energy in the primary battery 130 to the secondary charge and discharge controller 150. The electric energy received by the secondary charge and discharge controller 150 is transmitted to the secondary battery 160 and the measurement terminal 300, to power the measurement terminal 300, and to charge the secondary battery 160 at the same time.

[0110] This structure solves the problem of shortened battery life caused by frequent charging and discharging of batteries in current new energy-powered test piles.

[0111] Furthermore, when the electric switch 141 is disconnected, the primary battery 130 cannot supply power to the measurement terminal 300, thereby maintaining full power. When the electric switch 141 is connected, if there is sufficient sunlight and wind power, the measurement terminal 300 is directly powered by solar energy or wind power generation, and the primary battery 130 cannot supply power to the measurement terminal 300, thereby maintaining full power; if there is insufficient sunlight and wind power, the primary battery 130 will supply power to the measurement terminal 300, thereby reducing the number of charge and discharge times of the primary battery 130 and extending its service life.

[0112] Based on the above technical solution, in the embodiment of the present invention, by setting a voltage comparator and an on-off controller 142, when the power of the secondary battery 160 is higher than the first preset voltage, the electrical connection between the measurement terminal 300 and the primary battery 130 and the power generation unit 110 is disconnected, and the power of the secondary battery 160 is fully utilized to power the measurement terminal 300. When the power of the secondary battery 160 is lower than the second preset voltage, the electrical connection between the primary battery 130 and the power generation unit 110 is connected again to fully charge the secondary battery 160, thereby reducing the number of times the secondary battery 160 is charged and discharged. At the same time, the consumption of the primary battery 130 can be avoided when the power of the secondary battery 160 is sufficient, thereby reducing the number of times the primary battery 130 is charged and discharged, ensuring the energy storage performance of the battery, reducing maintenance costs, and solving the problem of shortened life due to frequent charging and discharging of batteries in the current test piles powered by new energy.
