specific Embodiment approach

[0039] The panel maintenance intelligent system in the water level amplitude range area is mainly used on the concrete panel 2 in the water level range area with large climate temperature difference. The drainage flower pipe 3 is arranged on the top of the concrete panel 2, and its main function is to make the maintenance water flow out from the drainage hole 17 on the pipe wall; The panel area of ​​the water level variable amplitude area is selected from 3 to 10 cm, and the thickness of the pipe wall is 0.1 to 0.5 cm; the drainage flower pipe 3 is provided with drainage holes 17, which are arranged in a line, with a diameter of 0.5 to 1 cm, and the hole spacing is usually 0.1 to 1 cm. 2m; the drainage flower pipe 3 is fixed on the concrete panel 2 with a bracket 4, the shape of the bracket 4 is semicircular, and the material of the bracket 4 is usually stainless steel sheet, the thickness of the stainless steel sheet is 0.1-0.3cm, the width of the stainless steel sheet is 1-2c...

Embodiment 3

[0045] The control method of the panel maintenance intelligent system in the water level amplitude range area is to collect the temperature and ambient temperature of the dam area from time to time through the temperature detector 8 and transmit the ambient temperature data to the controller 11 through the signal line, and at the same time through the evaporation detection device 20 Transmit the evaporation data of the reservoir water 1 in the dam area to the controller 11 through the signal line; compare and analyze the temperature and evaporation data with the standard data respectively through the controller 11, when the ambient temperature is lower or higher than the allowable value or When the evaporation of the reservoir water 1 exceeds the allowable value, the controller 11 automatically controls the opening of the electric valve 10, and sprays water to the concrete panel 2 through the drainage flower pipe 3 for maintenance; the water level in the water tank 13 is monitor...

Embodiment 4

[0047] The method for maintaining the concrete panel by using any one of the intelligent system for panel maintenance in the water level amplitude range is characterized in that it includes the following steps:

[0048] Step 1, arranging the above-mentioned system at the location of the concrete panel 2 to be maintained;

[0049] Step 2, setting the control parameters of the control system: setting the ambient temperature range value of the concrete panel 2, and setting the limit value of the evaporation of the reservoir water 1;

[0050] Step 3, start the temperature acquisition instrument 8, collect the temperature and ambient temperature of the dam area from time to time through the temperature acquisition instrument 8 and transmit the ambient temperature data to the controller 11 through the signal line, and simultaneously pass the evaporation detection device 20 to the dam area. The evaporation data of the reservoir water 1 is transmitted to the controller 11 through the ...

Abstract

The invention relates to a water level amplitude area panel maintenance intelligent system and a control and maintenance method. The water level amplitude area panel maintenance intelligent system includes a drainage floral tube fixedly arranged on a concrete panel, the drainage floral tube is in communication with the bottom of a water box through a first communication tube and an electrically operated valve, and the water box is connected with a water supply device; a temperature acquisition instrument for monitoring environmental temperature is installed on the concrete panel and on the middle part of the top of the drainage floral tube; the concrete panel is mounted with an evaporation quantity detection device for monitoring the evaporation amount of water in a dam body; and the temperature acquisition instrument, the water supply device and the evaporation quantity detection device are connected with a hardware control device through a signal line and automatically control the drainage operation of the drainage floral tube. The water level amplitude area panel maintenance intelligent system aims to solve the problem that the existing built concrete panel dam is prone to beingcracked due to the large temperature difference of climate and the improper maintenance of the water level amplitude area panel during the operation period.

Description

technical field [0001] The invention relates to an intelligent panel maintenance system and a control and maintenance method in a water level variable amplitude area, and belongs to the technical field of concrete panel dam protection. Background technique [0002] Concrete face dams have been widely used in water conservancy and hydropower projects. As the anti-seepage structure of the dam, the structural integrity of the concrete slab directly affects the safety of the dam and the benefits of the reservoir and power station. Panel cracks are a major failure form of panels. The main reasons are structural cracks caused by excessive stress or uneven stress, and concrete cracks caused by temperature stress and dry shrinkage stress. In order to reduce the cracks of the concrete itself, measures such as adding anti-cracking materials and strengthening maintenance during the construction period and the initial stage of water storage are generally adopted at present. The above-m...
