Description

Technical Field

[0001] This utility model belongs to the field of water conservancy and hydropower technology, and specifically relates to an antifreeze device for water conservancy and hydropower equipment. Background Technology

[0002] Antifreeze devices for water conservancy and hydropower equipment are protective measures to prevent equipment and pipelines in water conservancy and hydropower projects from being damaged by freezing in cold weather. Freezing can cause equipment to malfunction and even lead to serious consequences such as cracking and leakage.

[0003] Existing antifreeze devices cannot achieve the self-cleaning function of the filter screen in the exhaust fan. The filter screen is prone to accumulating dust and debris during use, which reduces the ventilation efficiency of the fan and affects the overall performance of the antifreeze device. In addition, the existing antifreeze devices have not effectively solved the problem of stable cable insertion in the design. In low temperature environment, the cable insertion part is prone to instability due to cold contraction or changes in the external environment. Utility Model Content

[0004] The purpose of this utility model is to provide an antifreeze device for water conservancy and hydropower equipment, so as to solve the problems mentioned in the background art that the existing antifreeze devices for water conservancy and hydropower equipment cannot perform self-cleaning of the filter screen in the exhaust fan and cannot stably insert cables into the antifreeze device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A frost protection device for water conservancy and hydropower equipment, comprising:

[0007] Insulated warehouse;

[0008] A movable door, which is rotatably connected to the outside of the insulated chamber;

[0009] A heat preservation mechanism is installed inside the heat preservation chamber. The heat preservation mechanism includes a heating coil, a heating pad, and a heat-conducting plate. The heating coil is fixedly installed inside the heat preservation chamber. A heating pad is provided at the top of the heating coil. A heat-conducting plate is fixedly connected to the top of the heating pad.

[0010] Preferably, the heating coil is a spiral coil, and the heating pad is fixedly connected to the bottom end of the heat-conducting plate by screws.

[0011] Preferably, the interior of the heat preservation chamber is equipped with instruments and equipment, the top of the heat preservation chamber is equipped with a cleaning mechanism, and an insertion mechanism is provided on one side of the exterior of the heat preservation chamber.

[0012] Preferably, the cleaning mechanism includes a motor, a rotating fan blade, and a cleaning scraper. The motor is installed at the top of the insulated chamber, and the output end of the motor is fixedly connected to the rotating fan blade. The outside of the rotating fan blade is fixedly connected to the cleaning scraper, and a dust filter screen is abutted against the outside of the cleaning scraper.

[0013] Preferably, the cleaning scraper abuts against the inner wall of the dust filter, and the surface of the dust filter has multiple holes and grooves.

[0014] Preferably, the insertion mechanism includes an insertion seat, an elastic abutment seat, and an insertion tube. The insertion seat is fixedly connected to the outside of one side of the insulation chamber. An elastic abutment seat is provided inside the insertion seat, and an insertion tube is inserted inside the insertion seat.

[0015] Preferably, the elastic abutment abuts against the outside of the insertion tube, and multiple elastic abutments are provided on the inner sidewall of the insertion seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) This utility model, through the setting of a motor, rotating fan blades, cleaning scraper and dust filter, enables the motor to drive the rotation of the fan blades to achieve air exchange inside the device when the machine is ventilating and cooling. During this process, the rotating fan blades drive the cleaning scraper to stick to the inner wall of the dust filter, thereby cleaning the dust filter. This design effectively realizes the self-cleaning function of the dust filter and ensures that the equipment maintains good ventilation efficiency during operation.

[0018] (2) By setting up an insertion seat, an elastic abutment seat, an insertion tube and a heat preservation mechanism, this utility model enables the elastic abutment seat to achieve elastic limit of the insertion tube during the installation process, so that the insertion tube can be stably abutted after being inserted into the seat. This design improves the stability of the insertion tube inside the insertion seat and ensures its reliable fixing effect. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figures 1-4 As shown, a frost protection device for water conservancy and hydropower equipment includes:

[0027] Insulated compartment 1;

[0028] Movable door 2 is rotatably connected to the outside of the insulated chamber 1;

[0029] The insulation mechanism 3 is located inside the insulation chamber 1. The insulation mechanism 3 includes a heating coil 301, a heating pad 302, and a heat-conducting plate 303. The heating coil 301 is fixedly installed inside the insulation chamber 1. The heating pad 302 is provided at the top of the heating coil 301. The heat-conducting plate 303 is fixedly connected to the top of the heating pad 302. The heating coil 301 is a spiral coil. The heating pad 302 is fixedly connected to the bottom of the heat-conducting plate 303 by screws. The insulation chamber 1 is equipped with instruments and equipment 4. A cleaning mechanism 5 is installed at the top of the insulation chamber 1. An insertion mechanism 6 is provided on the outside of one side of the insulation chamber 1.

[0030] Specifically, after the heating coil 301 is in operation, it heats the heating pad 302, so that when the temperature inside the insulation chamber 1 is too low, it can heat the inside and ensure that the instrument 4 will not malfunction due to the low external temperature.

[0031] As can be seen from the above, when the machine is ventilating and cooling, the motor 501 drives the rotating fan blade 502 to rotate, thereby performing the air exchange operation inside the device. At this time, the rotating fan blade 502 rotates, and the cleaning scraper 503 abuts against the inner wall of the dust filter 504, so that the cleaning scraper 503 can scrape and clean the dust filter 504, thereby realizing the self-cleaning operation of the dust filter 504.

[0032] Example 2:

[0033] refer to Figure 3 and Figure 4 As shown, the cleaning mechanism 5 includes a motor 501, a rotating fan blade 502, and a cleaning scraper 503. The motor 501 is installed at the top of the insulation chamber 1. The output end of the motor 501 is fixedly connected to the rotating fan blade 502. The cleaning scraper 503 is fixedly connected to the outside of the rotating fan blade 502. A dust filter 504 abuts against the outside of the cleaning scraper 503. The cleaning scraper 503 abuts against the inner wall of the dust filter 504. The surface of the dust filter 504 is open. The insertion mechanism 6 is provided with multiple slots and includes an insertion seat 601, an elastic abutment seat 602, and an insertion tube 603. The insertion seat 601 is fixedly connected to the outside of one side of the heat preservation chamber 1. The elastic abutment seat 602 is provided inside the insertion seat 601. The insertion tube 603 is inserted inside the insertion seat 601. The elastic abutment seat 602 abuts against the outside of the insertion tube 603. Multiple elastic abutment seats 602 are provided on the inner side wall of the insertion seat 601.

[0034] Specifically, after the fan blade 502 rotates, it drives the cleaning scraper 503 to rotate, which scrapes the bottom side of the dust filter 504, thereby automatically cleaning the dust filter 504.

[0035] As can be seen from the above, when the insertion tube 603 is inserted, the elastic abutment seat 602 can elastically abut and limit the insertion tube 603, which can stably abut and limit the insertion tube 603 after it is inserted into the insertion seat 601, thereby increasing the stability of the insertion tube 603 after it is inserted into the insertion seat 601.
