Description

Technical Field

[0001] The utility model relates to the technical field of concrete maintenance, and more specifically to maintenance equipment for a concrete base foundation in a power transmission line. Background Art

[0002] Transmission line towers are important load-bearing equipment for transmission lines. They mainly support transmission lines and bear the tension of transmission lines to ensure the linearity and safety of transmission lines. Therefore, transmission line towers must meet the requirements of precise installation and stable support. The concrete foundation under the transmission line tower is a component designed to meet and solve the above problems. It can disperse the deadweight of the transmission line tower and minimize the impact of the transmission line tower on the ground, thereby improving the stability of the transmission line tower.

[0003] Taking into account the long construction process of the transmission line tower foundation, part of the concrete foundation pouring work will be carried out in winter. However, the low temperature environment in winter can easily cause the surface temperature of the poured concrete to drop too quickly, resulting in temperature cracks, which in turn causes the strength of the concrete to decrease. This can cause great safety hazards after the transmission line is put into use. Therefore, the quality of the concrete foundation after pouring is particularly important.

[0004] At present, the following two maintenance methods are generally used for poured concrete foundations: 1. Conventional maintenance method: wrap a moisturizing film on the surface of the concrete foundation, and arrange staff to continuously water its surface to ensure the moisture of the surface of the concrete foundation; 2. Greenhouse maintenance method: set up a tent outside the concrete foundation, and cover the surface of the tent with insulation materials, and then burn coal or oil in the tent to increase the temperature. During this process, staff must be arranged to observe the situation in the tent at all times and sprinkle water on the concrete foundation to keep it moist.

[0005] However, the above two maintenance methods have major defects. The conventional maintenance method requires the use of a large amount of water, and its maintenance cost is relatively high. At the same time, this maintenance method judges the watering time based on manual experience, so there will still be problems such as cracks and color differences in the concrete foundation; and the greenhouse maintenance method will produce a large amount of harmful gases such as sulfur dioxide, nitrogen oxides, carbon monoxide, etc., which poses a major safety hazard and has a low maintenance efficiency.

[0006] Therefore, there is an urgent need for a maintenance equipment that can reduce environmental pollution, improve maintenance efficiency, reduce operating costs, and accurately control temperature and humidity while reducing safety hazards. Utility Model Content

[0007] The purpose of the utility model is to provide a maintenance device for a concrete base foundation in a power transmission line, so as to solve the problems existing in the background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides a maintenance device for a concrete base foundation in a power transmission line, comprising an electric heating steam generating module, a transmission pipe, a maintenance cover and a mobile base; the electric heating steam generating module comprises a steam unit and a water supply unit arranged on the upper surface of the mobile base, and a plurality of universal wheels are arranged on the lower surface of the mobile base;

[0009] The steam unit comprises a first shell, a water inlet and a steam outlet are provided on the first shell, a heating pipe is provided in the first shell, and two ends of the transmission pipe are respectively connected with the steam outlet and the curing cover;

The water inlet of the water pump is connected to the water outlet of the water tank, and the water outlet of the water pump is connected to the water inlet on the first shell.

[0011] Furthermore, the portable maintenance device also includes an intelligent maintenance module, which includes a control unit disposed on the mobile base and a wireless temperature sensor and a wireless humidity sensor disposed in the maintenance cover;

[0012] The control unit comprises an intelligent maintenance controller, and the wireless temperature sensor and the wireless humidity sensor are respectively connected to the intelligent maintenance controller by wireless communication.

[0014] The control unit also includes a steam generation controller, which is electrically connected to the electric contact liquid level meter, the water pump, the first valve and the heating tube respectively.

[0015] Furthermore, the water supply unit further comprises a second shell, the water tank is fixedly connected to the top of the second shell, and the water pump is installed in the second shell;

[0016] The control unit also includes a third shell, and the steam generation controller and the intelligent maintenance controller are both integrated and installed in the third shell.

[0017] Furthermore, a filter valve is installed at the water outlet of the water tank; a sewage outlet is installed at the bottom of the first shell, and a double one-way valve is installed at the water inlet of the first shell.

[0018] Furthermore, the steam unit, the water supply unit and the control unit are detachably mounted on the mobile base through a fixing portion, and a pair of support plates are fixedly connected to the bottom of the first shell, the second shell and the third shell, and each pair of support plates is symmetrically arranged along the vertical line of the first shell, the second shell and the third shell;

[0019] Each fixing part comprises a limiting plate and a buckle which are fixed on the movable base, and a groove which matches the supporting plate is formed inwardly on one side of each limiting plate corresponding to the buckle.

[0021] 1. The steam unit, water supply unit and control unit are detachably mounted on the mobile base through the fixing parts, so as to modularize the maintenance equipment and achieve the effect of convenient transportation;

[0022] 2. The control unit controls the start and stop of the steam unit to realize intelligent steam maintenance of the concrete foundation. This method enables the concrete foundation poured in winter to achieve constant temperature and constant humidity maintenance, thereby effectively ensuring the strength and quality of the concrete foundation after pouring. The concrete foundation is moisturized by high-pressure hot steam, so that the cement particles that have formed a gel in the concrete foundation after pouring can be fully hydrated, making it more stable after being converted into a crystal, thereby improving the maintenance effect of the concrete foundation;

[0023] 3. The water delivered into the first shell by the water pump is hydrothermally treated through the heating pipe to generate high-temperature and high-pressure steam, which is transmitted to the space surrounded by the maintenance cover through the transmission pipe.

At the same time, during the coal burning process, the greenhouse is easily ignited, and the steam maintenance method will not produce open flames in the space surrounded by the maintenance cover, thereby reducing safety hazards.

[0050] In one embodiment, the maintenance device further comprises a battery, which provides power for all electrical components and devices used in the maintenance device.

[0051] Working principle:

[0052] According to the project needs, the staff brings the various components of the maintenance equipment to the construction site, and then assembles the maintenance device. First, the first shell 41, the second shell 51 and the third shell 61 are fixed on the mobile base 1 through the fixing part 7. Then, the support frame is installed according to the size of the concrete foundation and is mounted on the concrete foundation. Finally, the maintenance cover 3 is mounted and fixed on the support frame, and the connection between the various components is established to complete the preparation work before the use of the maintenance equipment.

[0053] After completing the preparations before using the maintenance equipment, start the control unit 6, and then the steam generation controller controls the water pump 53 to inject water into the first shell 41 until the water level rises to the maximum height of the electric contact level gauge, and the water pump 53 stops supplying water. It should be noted that when the water level rises to the lowest heating position, the steam generation controller controls the heating pipe 42 to heat the water entering the first shell 41. During the continuous heating process of the heating pipe 42, the temperature of the water body continues to rise, thereby generating steam. The steam enters the maintenance cover 3 through the steam outlet, the first valve and the transmission pipe 2 in turn to maintain the poured concrete foundation. The first valve can be a DN15 ball valve to prevent steam from flowing back and improve the working efficiency of the equipment.

[0054] When the steam pressure reaches a set value, the heating pipe 42 stops heating the water body until the steam pressure drops to a set minimum pressure value, at which time the heating pipe 42 restarts to continue heating the water body.
