Description

Technical Field

[0001] The utility model belongs to the technical field of lightning rods, and in particular relates to a lightning rod with an integrated animal-repelling function in a tower-type photothermal mirror field. Background Art

[0002] Tower-type solar thermal power generation uses heliostats to precisely reflect sunlight onto a heat sink, which then stores the radiant energy in molten salt tanks. The location of the heliostat is primarily based on open, plain areas with ample sunlight.

[0003] During extreme thunderstorms, heliostats are highly susceptible to lightning strikes, causing significant economic losses. Furthermore, the cables between heliostats are located low, making them vulnerable to damage by animals near the heliostat field, causing failures. Currently, staff regularly patrol the field to remove animals, but this is difficult to do in a timely and efficient manner. Furthermore, the extensive patrols significantly consume staff energy and time, making it difficult to ensure reliable operation of the field. Therefore, there is a need for a device that can effectively prevent animal damage to cables and lightning strikes. Utility Model Content

[0004] To address the deficiencies in the prior art, the utility model provides a lightning rod with an integrated animal repelling function for a tower-type solar thermal mirror field, which can protect the heliostat from damage by lightning, while preventing animals from damaging cables and reducing the workload of inspection personnel.

[0005] The utility model adopts the following technical solutions.

[0006] A tower-type solar thermal mirror field lightning rod with an integrated animal repelling function comprises a lightning rod, a guide wire, a grounding body, and a support column. The support column is fixed to the ground, and a lightning rod is mounted on one side of the support column. One end of the lightning rod is connected to one end of the guide wire, and the other end of the guide wire is connected to the grounding body, which is connected to a capacitor.

[0007] The support column is provided with an ultrasonic generator and an LED lamp, which are arranged in sequence from top to bottom near the bottom of the support column;

[0008] The tower-type solar thermal mirror field has an integrated lightning rod with an animal-repelling function, which is arranged between two groups of heliostat triangular supports.

[0009] Furthermore, the support column is fixed to the ground through a support assembly, and the support assembly includes 3 groups, each group of support assemblies includes a support main support arm, a support auxiliary support arm and a base;

[0010] One end of the main support arm and the auxiliary support arm of the bracket in each support assembly is connected to the bracket column, and the other end of the main support arm and the auxiliary support arm of the bracket are connected to the base. The main support arm, the auxiliary support arm and the bracket column in each support assembly are located in the same plane.

[0011] Furthermore, the main support arm and the auxiliary support arm of the bracket are connected to the bracket column by means of buckles and bolts, and the connection position between the main support arm of the bracket and the bracket column is located above the connection position between the auxiliary support arm of the bracket and the bracket column;

[0012] The main support arm and the auxiliary support arm of the bracket are both fixed to the base by screws.

[0013] Furthermore, each support assembly group also includes two anchor rods, and two circular holes are provided in the middle of each base. Each circular hole is connected to an anchor rod, and one end of the anchor rod passes through the corresponding circular hole and penetrates into the soil layer.

[0014] Furthermore, the three groups of support components are connected through solar photovoltaic panels, and a solar photovoltaic panel is installed between each of the three main support arms of the bracket. The top of the solar photovoltaic panel is located at the connection between the two adjacent main support arms of the bracket and the bracket column, and the two side edges of the solar photovoltaic panel are attached to the two adjacent main support arms of the bracket.

[0015] Furthermore, the ultrasonic generator is connected to the solar photovoltaic panel via a photovoltaic cable, and the ultrasonic frequencies emitted by the ultrasonic generator include 2.4 GHz, 4.5 GHz and 6.0 GHz.

[0016] Furthermore, the LED lamp is connected to the solar photovoltaic panel via a photovoltaic cable. The LED lamp includes three LED lamp beads, and the three LED lamp beads light up and go out in sequence from left to right, in a continuous and repeated cycle.

[0017] Furthermore, the top of the lightning receptor is needle-shaped, and the distance between the top of the lightning receptor and the ground is 4500-5500 mm;

[0018] The lightning receptor is connected to the support column through buckles and bolts.

[0019] Furthermore, the bottom end of the grounding body is vertically inserted into the ground, and the top end is exposed to the ground. The distance between the top end of the grounding body and the ground is 150-250 mm, and the distance between the bottom end of the grounding body and the ground is 2500-3500 mm.

[0020] Furthermore, the capacitor is located underground, and the distance between the top of the capacitor and the ground is 1400-1600 mm.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. A large amount of charge is introduced into the grounding body and then to the capacitor through the lightning rod and guide wire. The capacitor absorbs the large amount of charge and carries the ultra-high voltage, thereby preventing lightning damage to the heliostat and ensuring the normal operation of the mirror field is not affected by lightning weather.

[0023] 2. The utility model drives away animals by using an ultrasonic generator that changes the frequency and controls the LED lamps that emit light in sequence, thereby preventing heliostat cables from being damaged by animals, reducing the inspection frequency and workload of inspection personnel, improving work efficiency, and reducing maintenance costs.

[0024] 3. By integrating solar photovoltaic panels to power the ultrasonic generator and LED lamps, the integrated animal-repelling lightning rod provided by the utility model does not rely on the power supply of the mirror field, and there is no need to lay complex wires, making the operation of the entire system more economical and efficient.

DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. The embodiments described in this application are only some embodiments of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] like Figure 1 As shown, the lightning rod 13 with an integrated animal repelling function in the tower-type solar thermal mirror field provided by the present invention is arranged between two groups of heliostat tripods 14. Each group of heliostat tripods 14 consists of three heliostats 16 and three heliostat brackets 17. The two groups of heliostat tripods 14 are connected by a cable 15.

[0035] like Figure 2 As shown, each tower-type solar thermal mirror field integrated lightning rod with animal repelling function includes a lightning rod 1, a guide wire 2, a grounding body 3, a capacitor 4, three solar photovoltaic panels 5, an ultrasonic generator 6, an LED lamp 7, a bracket column 9 and three groups of supporting components. Figure 2 The dotted line in the figure represents the ground, and the support column 9 is fixed to the ground through a support assembly. Each support assembly includes two anchor rods 8, a main support arm 10, an auxiliary support arm 11 and a base 12.

[0036] like Figure 2-3 As shown, one end of the main support arm 10 and the auxiliary support arm 11 of the bracket in each support assembly is fixed to the bracket column 9 by bolts and clips, and the connection position of the main support arm 10 and the bracket column 9 is located above the connection position of the auxiliary support arm 11 and the bracket column 9, and the other ends of the main support arm 10 and the auxiliary support arm 11 are fixedly connected to the base 12 by screws, and the main support arm 10, the auxiliary support arm 11 and the bracket column 9 are located in the same plane.

[0037] In a preferred but non-limiting embodiment, the support column 9 is a cylinder with a length of 3750 mm and a cross-sectional diameter of 90 mm. The main support arm 10 is 1500 mm long, 20 mm wide, and 10 mm thick. The auxiliary support arm 11 is 1223 mm long, 20 mm wide, and 5 mm thick. Furthermore, the main support arm 10 is fixed to the support column 9 at a position 964 mm above the ground, at a 40° angle to the ground. The auxiliary support arm 11 is fixed to the support column 9 at a position 418 mm above the ground, at a 20° angle to the ground.

[0038] like Figure 3 As shown, the included angle between two adjacent main support arms 10 of the bracket in horizontal projection is 120°, the three main support arms 10 of the bracket are located in an equilateral triangle, and the three bases 12 are located at the three end points of the equilateral triangle.

[0039] Each support assembly also includes two anchor rods 8, such as Figure 4 As shown, each base 12 has two central circular holes, each connected to an anchor rod 8. One end of the anchor rod 8 extends through the corresponding circular hole and penetrates the soil layer, thereby securing the bracket. In a preferred but non-limiting embodiment, the base 12 is 200 mm long, 80 mm wide, and 3 mm thick. The circular holes have a diameter of 22 mm, with the centers of the two holes located 60 mm from the left and right edges of the base 12. The anchor rod 8 is a cylinder 800 mm long with a cross-sectional diameter of 20 mm.

[0040] like Figure 6 As shown, when connecting the support assembly to the support column 9, first fix one end of the support main support arm 10 and the support auxiliary support arm 11 to the base 12 with screws. The other end of the support main support arm 10 is fixed to the support column 9 with a clip and bolts. The radius R1 of the inner circle of the clip is slightly larger than the distance L1 from the end point of the top of the support main support arm 10 away from the support column 9 to the center of the support column 9. The side of the top of the support main support arm 10 close to the support column 9 is tangent to the support column 9, and the bottom of the inner circle of the clip is in contact with the support main support arm 10. Similarly, the support auxiliary support arm 11 is fixed to the support column 9 with a clip and bolts, and the bottom of the inner circle of the clip is in contact with the support auxiliary support arm 11.

[0041] like Figure 2As shown, the dotted line in the figure represents the ground. A lightning receptor 1 is fixed to one side of a support column 9. The top of the lightning receptor 1 is needle-shaped, and the distance from the top of the lightning receptor 1 to the ground is 4500-5500mm. The bottom of the lightning receptor 1 is connected to the top of the guide wire 2, which is connected to the grounding body 3, which is connected to the capacitor 4. The bottom of the grounding body 3 is vertically inserted into the ground, with the top exposed above the ground. The distance between the top of the grounding body 3 and the ground is 150-250mm, and the distance between the bottom of the grounding body 3 and the ground is 2500-3500mm. The capacitor 4 is located underground, and the distance between the top of the capacitor 4 and the ground is 1400-1600mm.

[0042] like Figure 7 As shown, the lightning receptor 1 is fixed to one side of the support column 9 by means of a clip and a bolt, and the inner circle radius of the clip is the sum of the radius of the support column 9 and the radius of the lightning receptor 1.

[0043] In a preferred but non-limiting embodiment, the top of the lightning rod 1 is 5000 mm away from the ground, the lightning rod 1 is a galvanized round steel with a length of 4220 mm and a cross-sectional diameter of 20 mm, the guide wire 2 is a galvanized round steel with a length of 800 mm and a cross-sectional diameter of 10 mm, and the grounding body 3 is a copper-clad steel with a length of 3200 mm and a cross-sectional diameter of 16 mm; further, the grounding body 3 is vertically inserted into the ground, the length of the grounding body 3 buried underground is 3000 mm, and the length exposed to the ground is 200 mm, and the top of the capacitor 4 is 1500 mm away from the ground.

[0044] During thunderstorms, charged clouds appear above the heliostat field. The needle-shaped tip of lightning receptor 1 accumulates the most charge during electrostatic induction. Lightning receptor 1 forms a capacitor with the charged cloud. The pointed tip of lightning receptor 1 minimizes the area between the two plates of this capacitor, resulting in a small capacitance and, consequently, a small charge capacity. This concentration of charge accumulates most of the charge, so when the cloud is highly charged, the air between lightning receptor 1 and the cloud easily breaks down and becomes a conductor, creating a path between the charged cloud and lightning receptor 1. Lightning receptor 1 receives the high-voltage current, which is then transferred via conductor 2 to grounding element 3 and ultimately to capacitor 4. Capacitor 4, through its capacitive properties, carries the extremely high voltage, preventing the excessive voltage from impacting the heliostats. Furthermore, capacitor 4 can store a large amount of charge. Even when lightning creates a strong electric field, this stored charge provides short-term lightning protection for the heliostat field.

[0045] like Figure 2 As shown, an ultrasonic generator 6 and an LED lamp 7 are mounted on the support column 9, and the ultrasonic generator 6 and the LED lamp 7 are sequentially arranged from top to bottom near the bottom of the support column 9. Preferably, the upper surface of the ultrasonic generator 6 is 750 mm from the ground, and the upper surface of the LED lamp 7 is 418 mm from the ground.

[0046] A solar photovoltaic panel 5 is installed between each of the three bracket main support arms 10. The top of the solar photovoltaic panel 5 is located at the connection between the two adjacent bracket main support arms 10 and the bracket column 9. The two isosceles sides of the solar photovoltaic panel 5 are attached to the two adjacent bracket main support arms 10. The solar photovoltaic panel 5 provides power to the ultrasonic generator 6 and the LED lamp 7 through a photovoltaic cable, so that the integrated animal-repelling function lightning rod provided by the utility model does not rely on the power supply of the mirror field.

[0047] The ultrasonic generator 6 changes its ultrasonic frequency every minute. The ultrasonic frequencies are 2.4 GHz, 4.5 GHz, and 6.0 GHz. The upper limit of human hearing is 2.0 GHz, so the ultrasonic generator 6 will not affect field workers. It effectively repels animals with more sensitive hearing than humans, such as rabbits, pheasants, and rodents, that inhabit the field and damage heliostat cables. The intermittent change in ultrasonic frequency prevents these animals from becoming acclimated to the ultrasound.

[0048] like Figure 5 As shown, the LED lamp 7 includes three white-light emitting LED beads. These three LED beads light up and down sequentially from left to right, with only one LED bead emitting light at a time. The three LED beads repeatedly cycle through the light. This dynamic lighting LED lamp 7 can effectively repel animals that inhabit the heliostat field and could damage the heliostat cables 15, such as rabbits, pheasants, and various rodents.

[0049] In a preferred but non-limiting embodiment, the ultrasonic generator 6 is 200 mm long, 150 mm wide, and 110 mm thick; the LED lamp 7 is 300 mm long, 50 mm wide, and 50 mm thick; and the two isosceles sides of the solar photovoltaic panel 5 are 600 mm long.

[0050] The support column 9, the support main support arm 10, the support auxiliary support arm 11 and the base 12 are all made of TP347H stainless steel, and the anchor rod 8, the lightning rod 1 and the guide wire 2 are all made of galvanized Q235B round steel.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
