Description

Technical Field

[0001] The present application relates to the field of sensor technology, and in particular to a tilt sensor. Background Art

[0002] Photovoltaic cleaning robots are devices that clean photovoltaic array components. Currently, adjacent photovoltaic arrays are usually connected by bridges, and the bridges are used as tracks for photovoltaic cleaning robots to travel between photovoltaic arrays. After adjacent photovoltaic arrays are connected by bridges, photovoltaic cleaning robots can achieve long-distance cleaning. For fixed brackets commonly used in photovoltaic projects, adjacent fixed brackets can be connected by fixed bridges, and for tracking brackets commonly used in photovoltaic projects, adjacent tracking brackets can be connected by movable bridges (which can rotate with the tracking brackets). However, since the tracking brackets rotate in real time with the angle of the sun, in some cases, the operating angles of adjacent tracking brackets may be inconsistent, which will cause the movable bridge to twist, and the "angle inconsistency" information cannot be obtained by the photovoltaic cleaning robot in time, which will increase the risk of the photovoltaic cleaning robot getting stuck on the movable bridge or even falling off the movable bridge during operation. Utility Model Content

[0003] In order to solve the above problems, the present application provides a tilt sensor with ingenious design, simple structure, easy production and production, which can greatly save production costs. The technical solution adopted in the present application is as follows:

[0004] A tilt sensor, comprising:

[0005] A main body, wherein a receiving space connected in a double truncated cone shape is provided in the main body, wherein the double truncated cone shape is formed by two truncated cones with the same large bottom surface and the same taper being relatively connected with the large bottom surface as a connecting surface;

[0006] A ball, the ball being placed in the accommodation space;

[0007] A trigger device, the trigger device is arranged at two ends of the accommodating space;

[0008] When the inclination angle of the axis of the accommodating space is smaller than the taper of the accommodating space, the ball is located at the lowest point of the accommodating space; when the inclination angle of the axis of the accommodating space is larger than the taper of the accommodating space, the ball will move toward the lower end of the axis of the accommodating space, and then the ball triggers the trigger device located at the lower end of the accommodating space.

[0009] By setting up a double-conical shaped accommodation space, a ball and a trigger device, compared with the existing tilt sensors, the structure is simple and easy to manufacture and process. The tilt sensor of the present application does not need to obtain a specific tilt angle, but only needs to obtain whether it is in a tilted state; by setting the accommodation space to a double-conical shape, when the tilt sensor rotates with the movable bridge, as long as there is an inconsistency in the tilt angles between the two photovoltaic array components connected to the left and right of the movable bridge, and the inclination angle of the tilt sensor exceeds the taper of the accommodation space, the ball will trigger the trigger device, which is applicable to the situation where the photovoltaic array components are rotated to any angle.

[0010] In some embodiments, the trigger device is a pressure-sensitive sensor.

[0011] In some embodiments, it also includes a shell, a storage battery, and a control board. The body, the control board, the trigger device, and the storage battery are all arranged in the shell, and the storage battery is used to supply power to the control board and the trigger device.

[0012] The control board and the trigger device are powered by the energy storage battery, and there is no need to connect the control board and the trigger device to other external power supply lines, so there is no need to consider the wiring method of the power supply line, which reduces the requirements for the installation position of the tilt sensor.

[0013] In some embodiments, a solar cell is further included, and the solar cell is disposed on the outer surface of the shell and is used to charge the energy storage battery.

[0014] By arranging the solar cell, the energy storage battery does not need other charging operations, and the energy storage battery can continuously supply power to the trigger device.

[0015] In some embodiments, the control board further includes an antenna, and the antenna is used to send the signal of the trigger device to an external device.

[0016] By providing an antenna, it is no longer necessary to connect the trigger device to other external signal transmission lines, so there is no need to consider the wiring method of the signal transmission line, which reduces the requirements for the installation position of the tilt sensor.

[0017] In some embodiments, the ball is made of metal, and the diameter of the ball is greater than the installation height of the trigger device.

[0018] By setting the ball bearing to be a metal material, due to the high density of metal, compared with other materials of the same volume, such as lightweight plastic, the ball bearing made of metal material has better stability and is not easily triggered by mistake as the movable bridge frame sways in the wind.

[0019] In some embodiments, grooves are provided on the inner walls of the accommodation space of the trigger device from the lowest point of the accommodation space to both ends, and the balls move in the grooves.

[0020] In some embodiments, the containing space contains a solution.

[0021] By setting a solution in the accommodating space, the stability of the ball in the equilibrium position can be improved, making the ball less likely to be accidentally triggered due to the swaying of the movable bridge frame in the wind. At the same time, it can reduce the collision damage of the ball to the main body or the trigger device during the transportation and loading and unloading of the tilt sensor.

[0022] In some embodiments, the inner wall of the body and / or the balls are smoothed.

[0023] By smoothing the inner wall of the body and the ball, the smoothness of the ball rolling in the accommodating space can be improved.

[0024] The tilt sensor provided in the present application has at least one of the following beneficial effects:

[0025] 1. A tilt sensor provided by the present application has a double-conical shaped accommodation space, a ball and a trigger device. Compared with the existing tilt sensors, this has a simple structure and is easy to manufacture and process. The tilt sensor of the present application does not need to obtain a specific tilt angle, but only needs to obtain whether it is in a tilted state. By setting the accommodation space to a double-conical shape, when the tilt sensor rotates with the movable bridge, as long as there is an inconsistency in the tilt angle between the two photovoltaic array components connected to the left and right of the movable bridge, and the inclination angle of the tilt sensor exceeds the taper of the accommodation space, the ball will trigger the trigger device. This is applicable to the situation where the photovoltaic array components are rotated to any angle.

[0030] 6. The tilt sensor provided in the present application is configured such that the ball bearing is made of metal material.

[0039] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0040] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0041] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0042] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] refer to Figure 1-Figure 3 The present application provides a tilt sensor, including a main body 1, a ball 2 and a trigger device 3. The main body 1 is provided with a receiving space 4 connected in a double truncated cone shape, and the double truncated cone shape is formed by two truncated cones with the same large bottom surface and the same taper being relatively connected with the large bottom surface as the connecting surface. The ball 2 is placed in the receiving space 4, and the trigger device 3 is arranged at both ends of the receiving space 4. In the initial state, the axis of the receiving space 4 is in a horizontal state, and the ball 2 is located at the lowest point of the receiving space 4, that is, the ball 2 is located at the intersection of the two truncated cones. When the tilt sensor 8 tilts and the tilt angle exceeds the taper of the receiving space 4, the ball 2 will move to the lower end of the axis of the receiving space 4, thereby triggering the trigger device 3 located at the lower end of the receiving space 4.

[0045] Specifically, the tilt sensor 8 is installed on the movable bridge 6, and the axis of the receiving space 4 is horizontal in the initial state of the tilt sensor 8. At this time, the ball 2 will not roll to the two ends of the receiving space 4. When the rotation angles of the two photovoltaic array components 5 connected to the movable bridge 6 are inconsistent or asynchronous, the axis of the receiving space 4 of the tilt sensor 8 will be tilted. If the tilt angle of the axis of the receiving space 4 does not exceed the taper of the receiving space 4, the ball 2 will not roll. If the tilt angle of the axis of the receiving space 4 is greater than the taper of the receiving space 4, the ball 2 will roll, so that the ball 2 will trigger the trigger device 3 located at the lower end of the receiving space 4. It can be understood that after the ball 2 triggers the trigger device 3, the trigger device 3 can generate a trigger signal, which is transmitted to the control system or the photovoltaic cleaning robot 7. After obtaining the trigger signal, the control system or the photovoltaic cleaning robot 7 will control the photovoltaic cleaning robot 7 to prevent the photovoltaic cleaning robot 7 from driving onto the movable bridge 6, and at the same time, it can notify the maintenance personnel to handle the abnormal rotation of the photovoltaic array component 5.

[0046] It can be understood that the taper of the accommodating space 4 represents the sensitivity of the tilt sensor 8. The smaller the taper, the more sensitive the tilt sensor 8 is, and vice versa. The tapers of the two frustums forming the double frustum are the same, which ensures that no matter which end of the accommodating space 4 the ball 2 rolls to, its sensitivity is consistent.

[0047] Furthermore, in other embodiments, corresponding steps can be set at different distances of the truncated table of the accommodating space 4, and pressure sensing belts can be laid on the steps. Different steps can represent different tilt angles. When the ball 2 rolls to the corresponding step, the corresponding pressure sensing belt is triggered to generate a trigger signal. The control system or the photovoltaic cleaning robot 7 obtains the trigger signal, and the tilt degree of the movable bridge can be known, and corresponding decisions can be made.

[0048] In one embodiment, the tilt sensor 8 also includes a shell, a storage battery and a control board. The main body, the control board, the trigger device and the storage battery are all arranged in the shell. The control board and the trigger device 3 are powered by the storage battery. There is no need to connect other external power supply lines to the control board and the trigger device 3, so there is no need to consider the wiring method of the power supply line, which reduces the requirements for the installation position of the tilt sensor 8.

[0049] In one embodiment, the tilt sensor 8 further includes solar cells (photovoltaic cells). By providing the solar cells, the energy storage battery does not need other charging operations, and the energy storage battery can continuously supply power to the control board and the trigger device 3 .

[0050] It is understandable that the control panel also includes an antenna, which is used to send the signal of the ball 2 triggering the trigger device 3 to an external device, and the external device can be a control system or a photovoltaic cleaning robot 7.

[0051] It is worth noting that the trigger device 3 can be any one of the sensors such as pressure sensor, proximity sensor, Hall sensor, etc., as long as it can sense the arrival of the ball 2. Preferably, it is a pressure sensor, which has low procurement cost and stable working performance. It should be understood that different types of trigger devices 3 may need to be configured with balls 2 of different materials. For example, when the trigger device 3 is a Hall sensor, the ball 2 must be made of a material that can cause a change in the magnetic field.

[0052] It is understandable that the ball 2 is preferably made of a material with a higher density, such as metal or glass. Compared with other materials of the same volume, such as lightweight plastic, the ball 2 made of a material with a higher density has better stability and is not easily triggered by mistake as the movable bridge 6 sways with the wind. The body 1 is preferably made of plastic. Compared with other materials, such as metal, on the one hand, most plastics are cheaper than metals, and on the other hand, plastics are easier to process than metals.

[0053] In one embodiment, grooves (not shown) are provided on the inner wall of the accommodating space 4 from the lowest point of the accommodating space 4 to the trigger devices 3 at both ends, and the balls 2 move in the grooves.

[0054] In one embodiment, the accommodating space 4 contains a solution, and the solution can be a liquid such as water or oil that does not hinder the movement of the ball 2 but has a certain damping. By placing the solution in the accommodating space 4, the stability of the ball 2 in the equilibrium position can be improved, so that the ball 2 is not easily triggered by mistake due to the shaking of the movable bridge 6 with the wind, and the collision damage of the ball 2 to the body 1 or the trigger device 3 during the transportation and loading and unloading of the tilt sensor 8 can be reduced.

[0055] In order to prevent the ball 2 from getting stuck during rolling and to improve the smoothness of the rolling of the ball 2 in the accommodating space 4, one or both of the inner wall of the body 1 and the ball 2 can be smoothed, for example, by polishing or grinding, or by spraying a smooth coating.

[0056] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
