Description

Technical Field

[0001] The present application relates to the technical field of water conservancy and hydropower equipment, and more specifically, to an antifreeze device for water conservancy and hydropower equipment. Background Art

[0002] Water conservancy and hydropower projects often contain a large number of control and metering equipment such as valves and flow meters installed on water conservancy pipelines. In winter, the temperature is very low at night, which can easily cause the water in the equipment to freeze and thus damage the equipment.

[0003] The document with the prior art publication number CN216057702U provides an antifreeze device for water conservancy and hydropower equipment, which belongs to the field of water conservancy and hydropower technology, and includes a base plate and a chassis. The top of the base plate is fixedly connected to the equipment body, and both sides of the top of the inner cavity of the chassis are movably connected with threaded rods through bearings. The surfaces of the threaded rods are threadedly connected with threaded sleeves, and the opposite sides of the two threaded sleeves are fixedly connected to the equipment body. The heat generated by the heating network is blown into the chassis by a fan, so that the cold air in the chassis can be quickly mixed with the heated air, thereby accelerating the overall heating efficiency of the interior of the chassis, making the temperatures at various positions inside the chassis basically the same, and achieving the purpose of uniform and rapid thawing of the water conservancy equipment.

[0004] Although the above-mentioned prior art solutions can achieve the relevant beneficial effects through the structure of the prior art, they still have the following defects:

[0005] It completely relies on electric heating to prevent freezing, which consumes a lot of energy, and the equipment will be thawed only after it is frozen. When water freezes, its volume will expand, causing damage to the equipment.

[0006] Regarding the above-mentioned related technologies, the inventor believes that relying entirely on electric heating for anti-freezing consumes a lot of energy, and the equipment is thawed only after it is frozen. When water freezes, its volume expands, causing damage to the equipment.

[0007] In view of this, we propose an antifreeze device for water conservancy and hydropower equipment. Utility Model Content

[0010] 2. Technical solution

[0011] The technical solution of the present application provides an antifreeze device for water conservancy and hydropower equipment, comprising:

[0012] An antifreeze box, wherein a partition is fixedly installed in the antifreeze box;

[0013] The equipment body is installed in the inner cavity of the antifreeze box at the bottom of the partition, and both sides of the equipment body are fixedly connected with through pipes, and the through pipes penetrate the two sides of the antifreeze box;

[0014] A heat preservation mechanism is installed on the partition;

[0017] Through the above scheme, when there is sunshine during the day, the opening and closing mechanism opens, and the heat of the sunlight can be collected through the heat preservation mechanism. When the sun sets, the opening and closing mechanism automatically seals the antifreeze box, and the heat collected by the heat preservation mechanism can keep the antifreeze box warm, thereby preventing moisture in the equipment body from freezing and damaging the equipment.

[0018] Optionally, the heat preservation mechanism includes a through opening, the antifreeze box has a through opening on the top, a water tank is fixedly installed on the top of the partition, a heat collecting plate is fixedly installed on the top of the water tank, a plurality of heat conducting plates are fixedly installed on the bottom of the heat collecting plate, the heat conducting plates all penetrate into the inner cavity of the water tank, a heat absorbing plate is fixedly installed on the bottom of the inner cavity of the water tank, a plurality of fins are fixedly installed on the bottom of the heat absorbing plate, the fins penetrate into the bottom of the partition, the heat collecting plate, heat conducting plate, heat absorbing plate and fins are all copper plates, and electric heating coils are installed on both sides of the bottom of the partition.

[0019] Through the above scheme, when there is sunlight, the opening and closing mechanism opens to open the passage, and the solar collector can collect the sunlight heat and heat the water in the water tank through the heat conduction plate to achieve the purpose of heat storage. After the sun falls, the passage is closed by the opening and closing mechanism, and the water heat in the water tank provides heat to the antifreeze box at the equipment body through the heat absorption plate and fins to achieve the purpose of insulation, thereby effectively utilizing solar energy and achieving energy saving.

[0020] Optionally, the opening and closing mechanism includes a sealing plate, and the antifreeze box at the top of the through opening is slidably fitted with two sealing plates, and fixed boxes are fixedly installed on both sides of the top of the antifreeze box, and two liquid storage chambers are provided in the fixed box, and pistons are slidably clamped in the liquid storage chambers, and push-pull rods are fixedly installed on one end of the two pistons, and the push-pull rods pass through the end of the fixed box, and connecting plates are fixedly installed on the ends of the two sealing plates, and the connecting plates are fixedly connected to the push-pull rods, and a spring is installed between the piston and the inner wall of the fixed box, and the fixed box is a copper heat-conducting metal structure, and the spring is always in a compressed state, and a transparent glass plate is installed on the top of the antifreeze box through a support rod, and multiple rows of convex lenses are fixedly sleeved on the transparent glass plate, and the convex lenses on both sides of the transparent glass plate are located above the fixed box.

The push-pull rod pushes the sealing plate through the connecting plate. The two sealing plates move away from each other, and the opening is open. The sunlight irradiates the heat collecting plate to collect heat, and the aggregated light of the convex lens effectively heats the heat collecting plate to collect heat. After the sunlight falls, the fixed box loses heating, and the low temperature outside causes the low-boiling-point liquid to liquefy. The spring pushes the piston, causing the sealing plate to close and seal the opening, thereby avoiding heat loss in the antifreeze box, achieving the purpose of keeping the antifreeze box warm on cold nights, and effectively utilizing solar energy to achieve energy saving.

[0036] Furthermore, the electric heating coil 8 is connected to a power supply, and a temperature sensor is installed in the inner cavity of the antifreeze box 1 at the device body 3. In cold weather such as long-term cloudy days without sunlight, the insulation mechanism 5 cannot absorb external heat.

[0038] Working principle: The liquid storage chamber 63 can store liquids with low boiling points such as pentane and acetone. In cold weather, the volume of the liquid is small. After the sun comes out, the convex lens 69 can effectively aggregate the sunlight and irradiate it onto the fixed box 62, thereby heating the fixed box 62, causing the low-boiling-point liquid to vaporize and expand, thereby pushing the piston 64. The push-pull rod 65 pushes the sealing plate 61 through the connecting plate 66. The two sealing plates 61 move away from each other, and the through port 51 is open. The sunlight irradiates the heat collecting plate 53 to collect heat. The heat collecting plate 53 can collect the sunlight heat and heat the water in the water tank 52 through the heat conducting plate 54, thereby achieving the purpose of heat storage. After the sunlight falls, The fixed box 62 loses heating, and the low temperature outside causes the low-boiling-point liquid to liquefy. The spring 67 pushes the piston 64 to close the sealing plate 61 and seal the opening 51, thereby preventing the heat in the antifreeze box 1 from being lost. The water heat in the water tank 52 provides heat to the antifreeze box 1 at the equipment body 3 through the heat-absorbing plate 55 and the fins 56, thereby achieving the purpose of insulation, thereby being able to effectively utilize solar energy and achieve the purpose of energy saving.
