Description

Technical Field

[0001] The utility model belongs to the field of precipitation sensors, and in particular relates to a waterproof self-cleaning weighing precipitation sensor device. Background Art

[0002] The weighing precipitation sensor is a device commonly used in the meteorological field to measure precipitation, including a weighing sensor, a weighing cylinder, a protective shell, a collecting cylinder, and also includes a controller with waterproof function and a power box and other components. The protective shell and the collecting cylinder are integrated into one, and rainwater is collected by the collecting cylinder and enters the weighing cylinder. The diameter of the collecting cylinder is smaller than that of the weighing cylinder so that all the collected rainwater can flow into the weighing cylinder. In some areas with heavy snowfall, wind shields are also needed to increase the snow capture rate.

[0003] However, the existing water sensors have the following shortcomings: rainwater contains foreign particles, which are easily adhered to the inside of the weighing cylinder, affecting the weighing; the weighing cylinder is covered by a protective shell, leaving only a narrow collecting cylinder on the top, making it more troublesome to maintain and clean the weighing cylinder; directly setting a cleaning device on the weighing cylinder will affect the reading of the weighing cylinder during weighing. Utility Model Content

[0004] The purpose of the utility model is to provide a waterproof self-cleaning weighing precipitation sensor device in order to solve the above problems. The weighing cylinder is cleaned by a cleaning structure without affecting the weighing indication of the weighing cylinder.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A waterproof and self-cleaning weighing precipitation sensor device comprises a base, a protective shell fixed to the base and having a collecting cylinder on the top, a weighing sensor arranged on the base, and a weighing cylinder located on the weighing sensor. A cleaning mechanism is arranged in the protective shell, and the cleaning mechanism comprises an annular sleeve inverted on the upper edge of the weighing cylinder, and blades are arranged on the upper surface of the annular sleeve. A motor is arranged on the outer wall of the collecting cylinder, and a pair of mutually symmetrical driving blades are arranged on the side of the output shaft end of the motor, and the driving blades are used to move the blades to drive the annular sleeve to rotate. An L-shaped cleaning rod that fits the inner wall of the weighing cylinder is arranged below the annular sleeve.

[0007] As a further optimization scheme of the utility model, a power box and a controller are arranged under the base. The wire connectors of the power box and the controller are connectors that meet the waterproof standards. The power box and the controller are both arranged under the base and have a certain degree of rain shelter function. The wire connectors of the power box and the controller need to meet the waterproof standards and have sealing structures such as sealing rings or sleeves inside to prevent moisture penetration.

[0008] As a further optimization solution of the utility model, a guide wheel is provided at the sliding position between the annular sleeve and the upper edge of the weighing cylinder to increase the smoothness of the annular sleeve when rotating.

[0009] As a further optimization scheme of the utility model, a brush is provided on the surface of the L-shaped cleaning rod that contacts the inner wall of the weighing cylinder, and the end of the L-shaped cleaning rod is rotatably connected to the center of the bottom wall of the weighing cylinder, which helps the L-shaped cleaning rod to clean the inner wall of the weighing cylinder, and the end of the L-shaped cleaning rod is reinforced by rotation to prevent the L-shaped cleaning rod from collapsing and deforming under force.

[0010] As a further optimization scheme of the utility model, a drain solenoid valve is provided at the bottom of the weighing cylinder. The drain solenoid valve is suspended at one end away from the weighing cylinder. The drain solenoid valve is electrically connected to the controller. The drain solenoid valve is used to drain water before the weighing cylinder is full of water to prevent overflow into the protective shell so as to continue measuring.

[0011] As a further optimization scheme of the utility model, the cleaning mechanism also includes a detergent adding component, which includes an adding pump and a nozzle arranged on the outer wall of the collecting cylinder, and the inner wall of the protective shell is provided with a detergent storage tank connected to the adding pump, and the upper end of the detergent storage tank is provided with an adding port that passes through the protective shell, and the adding pump is electrically connected to the controller. By setting the detergent to spray the detergent directly onto the inner wall of the weighing cylinder, it can be mixed with rainwater before being discharged, thereby improving the cleaning efficiency.

[0012] The beneficial effects of the utility model are:

[0013] The utility model achieves the purpose of cleaning the weighing cylinder by arranging an annular sleeve and an L-shaped cleaning rod on the upper edge of the weighing cylinder. The driving mode of the annular sleeve is driven by blade shifting, and the output end of the motor is provided with mutually symmetrical driving leaves. When drainage cleaning is required, the driving structure rotates the driving leaves to shift the blades, thereby driving the annular sleeve to rotate. When measuring rainfall, the driving leaves are placed horizontally, and the horizontally placed driving leaves do not touch the leaves, thereby preventing the weighing cylinder from being rigidly connected to the external device and affecting the weighing.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example 1

[0024] like Figure 1-7 As shown, a waterproof self-cleaning weighing precipitation sensor device includes a base 1, a protective shell 2 fixed to the base 1 and with a collecting cylinder 3 on the top, a weighing sensor 5 arranged on the base 1, and a weighing cylinder 4 located on the weighing sensor 5. A cleaning mechanism 6 is arranged in the protective shell 2, and the cleaning mechanism 6 includes an annular sleeve 61 inverted on the upper edge of the weighing cylinder 4, and a blade 63 is arranged on the upper surface of the annular sleeve 61. A motor 64 is arranged on the outer wall of the collecting cylinder 3, and a pair of symmetrical driving blades 65 are arranged on the side of the output shaft end of the motor 64. The driving blades 65 are used to move the blades 63 to drive the annular sleeve 61 to rotate, and an L-shaped cleaning rod 66 that fits the inner wall of the weighing cylinder 4 is arranged below the annular sleeve 61.

[0025] As shown in the figure, the driving blade 65 has two, when not cleaning, Figure 5 As shown, the driving blade 65 has no contact with the blade 63 on the annular sleeve 61, so as to prevent the contact force from affecting the weighing in the vertical direction. Figures 6 to 7As shown, the motor 64 drives the driving blade 65 to rotate slowly. When one of the driving blades 65 contacts the blade 63, a thrust is exerted on the blade 63. This thrust acts on the annular sleeve 61, causing the annular sleeve 61 to be forced in the tangential direction and thus rotate. It should be noted that the process between the driving blade 65 and the blade 63 involves contact - push - separation - re - contact. Therefore, the rotation process of the annular sleeve 61 is intermittent. The motor 64 rotates slowly to prevent the annular sleeve 61 from continuing to rotate a long distance due to inertia during the power - interruption process. To prevent the end of the driving blade 65 from exactly contacting the end of the blade 63 when cutting into the gap of the blade 63 and causing jamming, a small number of elastic components can also be set at the end of the driving blade 65 or the upper end of the blade 63. Slow rotation can also reduce the impact generated when the driving blade 65 rotates into the gap of the blade 63.

[0026] A power supply box 7 and a controller 8 are arranged below the base 1. The wire connectors of the power supply box 7 and the controller 8 both use connectors that meet the waterproof standard. The power supply box 7 and the controller 8 are both arranged below the base 1, having a certain degree of rain - shelter function. Moreover, the wire connectors of the power supply box 7 and the controller 8 need to meet the waterproof standard and have sealing structures such as sealing rings or sleeves inside to prevent water penetration.

[0027] Guide wheels 62 are arranged at the sliding part between the annular sleeve 61 and the upper edge of the weighing cylinder 4 to increase the smoothness of the rotation of the annular sleeve 61.

[0028] The surface of the L - shaped cleaning rod 66 in contact with the inner wall of the weighing cylinder 4 is provided with a brush 67. And the end of the L - shaped cleaning rod 66 is rotatably connected to the center of the bottom wall of the weighing cylinder 4, which helps the L - shaped cleaning rod 66 clean the inner wall of the weighing cylinder 4. And the end of the L - shaped cleaning rod 66 is strengthened by rotation to prevent the L - shaped cleaning rod 66 from collapsing under force.

[0029] A drain solenoid valve 401 is arranged at the bottom of the weighing cylinder 4. One end of the drain solenoid valve 401 away from the weighing cylinder 4 is suspended. The drain solenoid valve 401 is electrically connected to the controller 8. The drain solenoid valve 401 is used to drain water before the weighing cylinder 4 is full to prevent it from overflowing into the protective shell 2, which helps to waterproof the inside of the protective shell 2 and prevent it from affecting the weighing sensor 5. The suspended setting is to make the weighing cylinder 4 not rigidly connected to components other than the weighing sensor 5 to prevent affecting the weighing indication.

[0030] The cleaning mechanism 6 also includes a detergent adding component, which includes an adding pump 68 and a nozzle 610 arranged on the outer wall of the collecting cylinder 3. The inner wall of the protective shell 2 is provided with a detergent storage tank 69 connected to the adding pump 68. The upper end of the detergent storage tank 69 is provided with an adding port that passes through the protective shell 2. The adding pump 68 is electrically connected to the controller 8. By setting the detergent to spray the detergent directly onto the inner wall of the weighing cylinder 4, it can be mixed with rainwater before being discharged, thereby improving the cleaning efficiency.

[0031] The specific implementation method is as follows: the purpose of cleaning the weighing cylinder 4 is achieved by setting an annular sleeve 61 and an L-shaped cleaning rod 66 on the upper edge of the weighing cylinder 4. The driving method of the annular sleeve 61 is to drive by the blade 63, and the output end of the motor 64 is provided with mutually symmetrical driving blades 65. When the drainage cleaning is required, the driving structure rotates the driving blade 65 to drive the blade 63, thereby driving the annular sleeve 61 to rotate. When the rainfall is measured, the driving blade 65 is as follows. Figure 4 As shown, the horizontal driving blade 65 does not touch the blade 63, thereby preventing the weighing cylinder 4 from being rigidly connected to an external device and affecting the weighing.

[0032] During operation, rainwater passes through the collecting cylinder 3 and enters the weighing cylinder 4. The weighing sensor 5 transmits the reading to the controller 8 in real time. When the weight of rainwater reaches the discharge standard, the controller 8 sends a signal to the drainage solenoid valve 401, the adding pump 68, and the motor 64. The drainage solenoid valve 401 drains water and cleans at the same time. The adding pump 68 sprays detergent. The motor 64 drives the annular sleeve 61 to rotate to realize the self-cleaning function.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
