[0023] The following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0024] In the following description, many specific details are explained in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the connotation of the present invention. Similar promotion, therefore, the present invention is not limited by the specific embodiments disclosed below.
[0025] Such as figure 2 As shown, the present invention discloses a tree pit bottom support plate system, which includes two support plate bodies 1, each of which is provided with a rectangular notch 2 in the middle of one side of the support plate body 1, and two support plate bodies 1. The parts with the rectangular notches 2 are arranged oppositely, and the two oppositely disposed rectangular notches 2 form a trunk through hole, and the trunk passes through the trunk through hole. Each supporting plate body includes a number of integrated vertical plates 3, and a number of horizontal plates 4 are arranged at intervals between every two vertical plates 3, and the horizontal plates 4 are arranged at intervals along the front and rear direction of the supporting plate body 1 (this The front, back, left and right mentioned in the application refer to figure 2 The interval distance can be fixed or variable. In general, the interval is set to a certain value for aesthetics. The horizontal plates 4 on the same straight line are connected together by a connecting rod 5, such as Figure 4 As shown, the horizontal plate 4 opposite to the rectangular notch 2 and located on the outermost side is provided with a notch 6, and the horizontal plate 4 with the notch 6 is fixedly connected to the vertical plate 3 located on the outermost side, so that this part of the horizontal plate 4 is always in a vertical state, most of the horizontal plates 4 are connected by different connecting rods, and the horizontal plates 4 of other parts are fixedly connected with the connecting rod 5, and rotate with the rotation of the connecting rod 5.
[0026] A drive assembly is provided in the gap 6 (each support plate body 1 is provided with a drive assembly), and the drive assembly includes a stepping motor 7, a transmission chain 8 and a plurality of transmission wheels 9. The transmission wheel 9 is located at the outer end of each connecting rod 5. All the transmission wheels 9 are connected together by the same transmission chain 8. The enlarged structure diagram of the connection between the horizontal plate and the vertical plate is as follows Figure 5-6 Shown. The power output end of the stepping motor 7 is fixedly connected to one of the transmission wheels 9, one of the vertical plates 3 is provided with a liquid level sensor 10 on the lower side, and one of the vertical plates is embedded with a water sensor 11 on the upper side. (The water sensor 11 should be exposed outside), the controller 12 is fixed on the lower side of one of the vertical plates 3, and the liquid level sensor 10 and the water sensor 11 are connected to the signal input terminals of the controller 12, such as Figure 7 Shown is the electrical principle block diagram of the support board system in the implementation of the present invention. It should be pointed out that, for the convenience of wiring, the liquid level sensor 10, the water sensor 11 and the controller 12 can be on the same vertical plate, and in order to connect the stepping motors on the two supporting plate bodies 1, they can be installed on the whole The underside of the support board body 1 is wired. The water pump is located in the controller. The liquid inlet of the water pump is connected with a liquid inlet pipe, which extends to the bottom of the tree pit, and the liquid outlet of the water pump is connected with a liquid outlet pipe. The plate 3 passes through and extends to the outside of the support plate system. Generally, the liquid outlet pipe extends under the road teeth to allow water or rainwater to drain into the sewer on the road.
[0027] The system uses only one controller. The controller simultaneously receives the information transmitted by the sensors on the two supporting plate bodies, and simultaneously controls the actions of two stepping motors and one water pump. In the initial use state, the horizontal plate 4 other than the horizontal plate 4 with the notch 6 is horizontal, and the horizontal plate 4 with the notch 6 is always vertical; when the water sensor 11 senses that water or rain is injected into the tree pit 13 When the time, the controller 12 controls the stepping motor 7 to move, the stepping motor 7 drives the connecting rod 5 to rotate, and the connecting rod 5 drives the horizontal plate 4 (the horizontal plate without the gap 6) to rotate, so that the horizontal plate 4 turns from horizontal to vertical Status like image 3 As shown, water can smoothly enter the tree pit; when the water or rain entering the tree pit reaches above the level sensor 10 for a period of time, the controller 12 controls the water pump to perform pumping action until the water in the tree pit 13 Water or rain is below the liquid level sensor 10 for a period of time. At this time, the controller 12 controls the action of the stepping motor 7. The stepping motor 7 drives the connecting rod 5 to rotate, and the connecting rod 5 drives the horizontal plate 4 to rotate (without gap 6 horizontal plate), the horizontal plate 4 in the vertical state is transformed into the horizontal state, and the gap area between the horizontal plate 4 and the vertical plate 3 is reduced.
[0028] In order to obtain electric energy conveniently, the support board system also includes thin-film solar cells, the thin-film solar cells are arranged around the outer circumference of the trunk, and the power output end of the thin-film solar cell is connected to the power input end of the controller 12, so The controller supplies power to the liquid level sensor 10, the water sensor 11, and the water pump.
[0029] In order to make the perception of information more accurate, there are several water sensors 11, and when any one of the water sensors senses water or rain for a period of time (to prevent frequent start and stop), the controller controls the action of the connecting rod. In the same way, there are several liquid level sensors 10, and when any one of the liquid level sensors senses water level or rain level information and stays above it for a period of time, the controller controls the action of the water pump and the connecting rod. The two supporting plate bodies 1 are provided with mutually matched locking parts at positions close to the rectangular notches, and the two supporting plate bodies are connected as a whole by the mutually matched locking parts, which can effectively prevent the supporting plate system from being stolen.
[0030] Different from the prior art, all the horizontal boards and vertical boards in the support board at the bottom of the tree roots are always arranged vertically, most of the horizontal boards in the supporting board body of the present application are arranged horizontally in the initial state, which can not only prevent people from falling into the tree pit It can also effectively prevent fallen leaves, debris, etc. from falling into the tree pit, reducing the frequency and intensity of tree pit cleaning, thereby reducing the labor intensity of cleaners.
[0031] In addition, when the water sensor senses that water or rain is injected into the tree pit, the controller controls the action of the stepping motor, and the stepping motor drives the connecting rod to rotate, and the connecting rod drives the horizontal plate to rotate, turning the horizontal plate from the horizontal state to the vertical State, water or rain can enter the tree pit smoothly, and when the water sensor does not sense water or rain within a period of time (to prevent frequent activation of this function), under the control of the controller, the stepper motor drives the horizontal plate to The initial state can effectively avoid the inconvenience of watering and the problem of rainwater absorption.
[0032] When the water or rain entering the tree pit reaches above the level sensor for a period of time, in order to reduce the inconvenience caused by excessive water and rain to pedestrians, the controller controls the water pump to perform pumping action until the water in the tree pit or When the rain is below the liquid level sensor for a period of time (to prevent frequent activation of this function), the controller controls the action of the stepper motor, the stepper motor drives the connecting rod to rotate, and the connecting rod drives the horizontal plate to rotate so that the horizontal plate is horizontal State, reduce the gap area between the horizontal board and the vertical board, at this time, it can also effectively reduce the evaporation of water, so that the trees can absorb more water, which is more conducive to growth.
