Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a non-pressure water inlet trash rack deicing device. Background Art

[0002] Water conservancy and hydropower projects refer to various projects for the purpose of flood control, irrigation, power generation, water supply, waterlogging control, water environment management, etc. Its main engineering contents include the construction of hydraulic structures, hydropower stations, pumping stations, hydraulic machinery installation, hydraulic metal structure manufacturing and installation, electrical equipment installation, automation information system, environmental protection engineering construction, soil and water conservation engineering construction, land improvement engineering construction, etc. At the same time, it can provide a good environment and material conditions for industrial and agricultural production and people's lives. Trash racks are needed for the non-pressure water inlets in water conservancy and hydropower projects to block aquatic plants, driftwood and other debris carried by the water flow.

[0003] Common non-pressure water inlet trash racks are usually composed of structures such as frames, baffles, bars and blades. They are first installed at the corresponding position of the non-pressure water inlet. When the water flows through, the bars and blades can intercept aquatic plants, driftwood and other debris in the water flow. This is the common structure and use of non-pressure water inlet trash racks. When the traditional non-pressure water inlet trash rack is used in severe cold weather or areas, the trash rack freezes in the water. Due to the effect of ice on the rack body, the bars of the trash rack are blocked, resulting in a reduction in the water inlet area or even a cut-off, causing the water inlet conditions of the water inlet flow channel to change. Some non-pressure water inlet trash racks are installed with heating components or heated media (liquids, gases, etc.) are installed on the bars or injected into the internal flow of the bars to increase the temperature of the bars themselves, thereby removing the ice on the bars. However, in this method, since the bars are usually immersed in the water of the non-pressure water inlet, the temperature of the bars will be lost as the water flows, which will reduce the deicing effect and even make it impossible to melt the ice, thereby causing the water conservancy project to be unable to be used normally. Therefore, a non-pressure water inlet trash rack deicing device is proposed. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a pressure-free water inlet trash rack deicing device to solve the technical problem that the flow of water will cause the temperature of the rack bars to lose, thereby reducing the deicing effect or even failing to melt the ice.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a non-pressure water inlet trash rack deicing device, comprising:

[0008] The trash rack body and the non-pressure water inlet are arranged just below the bottom of the trash rack body, and the side support plates are installed on one side of the top center of the non-pressure water inlet;

[0009] A hydraulic rod is arranged on the top of the side support plate, and the telescopic ends of the hydraulic rod extend downward through the top of the side support plate and are connected to a cross-connecting plate. Electric heating rods are installed at the front and rear ends of the top of the cross-connecting plate, and a heat conducting plate is added at the center of the bottom end of the electric heating rod;

[0010] The heat-absorbing horizontal plate is arranged directly below the bottom of the cross-connecting plate and fits tightly with the bottom of the heat-conducting plate, and ice-breaking cone heads are evenly installed at the bottom of the heat-absorbing horizontal plate. Trash is intercepted at the pressureless water inlet through the structures such as the bars and blades on the trash rack body. The electric heating rod can be powered on and heated by external hydroelectric power generation equipment or solar power generation equipment, and the heat is guided to the heat-absorbing horizontal plate by the heat-conducting plate, so that the ice-breaking cone head is heated and heated. At the same time, the hydraulic rod can drive the cross-connecting plate and the heat-absorbing horizontal plate to descend on the side support plate, so that the ice-breaking cone head heats and breaks the frozen water surface. On the one hand, the heating component and the ice-breaking cone head can achieve a double deicing effect, speed up the deicing speed, and avoid the loss of heat that reduces the deicing effect or even fails to melt the ice. On the other hand, since the heat-absorbing horizontal plate fits the trash rack body, the heat can be guided to the trash rack body, thereby increasing the temperature of the trash rack body, so that the inner cavity of the trash rack body can be deiced.

[0011] Preferably, a connecting block is installed at the bottom center of the cross-connecting plate, and a guide cross bar is installed at the center of the front and back sides of the connecting block. The cross-connecting plate can be connected between the connecting block and the guide cross bar.

[0012] Preferably, the surface of the guide crossbar is sleeved with a compression spring, and the ends of the guide crossbar are slidably connected with positioning plugs, which fit tightly with the corresponding compression springs. The positioning plugs are on the guide crossbar, and under the action of the compression springs, the positioning plugs can be continuously maintained at the end position of the guide crossbar.

[0013] Preferably, the center of the front and rear ends of the top of the heat absorbing cross plate are both installed with positioning blocks, and the center of the inner side of the positioning block is provided with positioning slots, which correspond to the corresponding positioning plugs. The positioning plugs are on the guide cross bar, and under the action of the extrusion spring, the positioning plugs can be inserted into the corresponding positioning slots on the positioning block for connection, so that the cross connecting plate and the heat absorbing cross plate are connected, and the disassembly and assembly operation between the cross connecting plate and the heat absorbing cross plate is convenient.

[0014] Preferably, a side plate is longitudinally installed at the top center of the non-pressure water inlet, and a rotating handle is added at the top center of the side plate. The rotating handle can be rotated at the top of the side plate and the rotating direction of the rotating handle can be changed.

[0015] Preferably, a threaded screw is installed at the center of the inner cavity of each side vertical plate and is coaxially connected to the corresponding rotating handle, and a sliding block is sleeved on the lower part of the outer surface of the threaded screw and is connected to the corresponding part of the trash rack body. The rotating handle drives the threaded screw to rotate on the side vertical plate, and the sliding block can drive the trash rack body to move up and down according to the direction of the threaded screw, so as to facilitate the adjustment of the connection relationship between the trash rack body and the non-pressure water inlet.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a non-pressure water inlet trash rack deicing device, which has the following beneficial effects:

[0018] The de-icing device for the trash rack at the pressureless water inlet intercepts trash at the pressureless water inlet through structures such as bars and blades on the trash rack body. The electric heating rod can be energized and heated by external hydroelectric power generation equipment or solar power generation equipment, and the heat can be guided to the heat-absorbing horizontal plate by the heat-conducting plate, so that the ice-breaking cone head is heated and heated. At the same time, the hydraulic rod can drive the horizontal connecting plate and the heat-absorbing horizontal plate on the side support plate to descend, so that the ice-breaking cone head heats and breaks the frozen water surface. In this way, on the one hand, a dual de-icing effect can be achieved by the heating component and the ice-breaking cone head, the speed of de-icing can be accelerated, and the situation that the de-icing effect is reduced or even the ice cannot be melted due to heat loss can be avoided; on the other hand, since the heat-absorbing horizontal plate is in contact with the trash rack body, the heat can be guided to the trash rack body, thereby increasing the temperature of the trash rack body, so that the inner cavity of the trash rack body can be de-iced.
