Description

Technical Field

[0001] This invention belongs to the technical field of road maintenance equipment, and particularly relates to a testing method and testing device for a snow blower. Background Technology

[0002] High-latitude regions experience long winters accompanied by heavy snowfall, leading to complex snow accumulation conditions such as "blowing snow." Blowing snow is characterized by its long duration, high frequency, large volume and compact size, and wide coverage. Conventional snow removal equipment cannot effectively remove snow caused by blowing snow; currently, only snow blowers can efficiently remove snow from roads.

[0003] For manufacturers of snowplows, performance testing is essential before a newly designed product is put into use. The complex snow conditions these snowplows need to withstand are typically only encountered in specific seasons and high-latitude regions. Testing is constrained by time and space and is costly. Snowplows are generally used in disaster relief and rescue operations, often requiring prolonged periods of high-intensity work. Users have very high requirements for the reliability and stability of the equipment over extended periods, making long-term reliability and stability testing indispensable.

[0004] To address the problems existing in the snow blower testing described above, an alternative method is considered to complete the snow blower testing process. For vehicle testing, an automotive test platform can be used, but in this process, the working device can only run idle and cannot simulate the actual snow removal and throwing process. Currently, there is a need for a method and device to simulate the snow breaking, snow collection, and snow throwing process during the operation of a snow blower.

[0005] Regarding testing methods for snow blowers, foreign equipment manufacturers are mainly located in high-latitude regions, which have more comprehensive snow testing conditions, making it convenient to conduct snow-throwing tests directly using real snow. However, for equipment manufacturers in mid- and low-latitude regions, conducting long-term tests using real snow means enormous human and economic costs.

[0006] In other industries, where snow accumulation is needed in non-snow-prone areas, snowmaking machines are typically used to artificially create small areas of snow. The larger the snow-covered area, the higher the cost of snowmaking, as is the case with many indoor ski resorts. Document CN112930463A discloses a method and apparatus for generating large amounts of snowfall in ski resorts, theme parks, and testing and training facilities used in conjunction with drones, motor vehicles, autonomous vehicles, and aircraft components. It can generate large amounts of snowfall in areas with temperatures above or below freezing, and the snowflake size is variable, with the output capacity covering a large area. However, the equipment and operating costs involved in this invention are high, making it unsuitable for long-term testing of snowplows.

[0007] In the field of snow and ice removal, document CN109507226B discloses an experimental device and method for melting snow and ice on concrete bridge decks using an electrothermal method. This device simulates snow and ice melting on concrete bridge decks. The experimental device includes heating cables, a concrete bridge deck template model, an insulation layer, temperature sensors, and temperature monitoring equipment. The melting effect is achieved by heating the cables arranged on the bridge deck model. While this invention is an experimental device for snow and ice melting, it operates on a different principle than a snow blower, and its experimental device and method are not relevant to snow blowers.

[0008] Currently, no cost-effective testing alternatives have been found for snow blower products. The testing method and device for snow blowers described in this invention have low requirements for equipment materials and site conditions, and the scheme is simple and easy to conduct effective tests.

[0099] Example 2

[0100] The testing device for the snow blower in this embodiment includes a detachable ramp platform 1, a water storage tank 2, and a water return device 3, such as... Figure 1 As shown.

[0101] The ramp includes two front ramps and two rear ramps. The two rear ramps are fixed together by connecting rods. By selecting connecting rods of different lengths, the width of the ramps can be changed to accommodate vehicle models of different widths. Figure 2 As shown. A movable stop mechanism is provided on the rear ramp platform. After the vehicle is positioned, the stop protrudes, restricting the vehicle's downward movement.

The support 301 elevates the water collection tank 302, aligning its inlet with the snow-throwing nozzle of the snow blower to collect water thrown by the snow blower. The return water trough 303 allows the water in the water collection tank 302 to flow back to the original water storage tank 2 under gravity for recycling. Figure 3 As shown, the water flow rate is monitored during the water recirculation process to determine the snow-throwing capacity of the snow blower.

[0105] The testing method for the snow blower described in this embodiment is as follows:

[0106] (1) Select a spacious and flat site, install the test device ramp 1 in a suitable position and fix it firmly, check and clean up any potential risks, and make preparations before the test.

[0107] (2) Drive the snow blower to the test site and reverse it to the set position on the ramp 1. The block mechanism protrudes to restrict the vehicle from sliding down.

[0112] (7) The working device of the snow blower starts to work. The auger of the snow collection device draws water in and the snow blower fan throws the water out along the snow throwing tube and into the water collection tank 302. The water in the water collection tank 302 flows back to the original water storage tank 2 along the return water channel 303. During the process, water is replenished to the water storage tank 2 in time to avoid the water level dropping due to some water spilling on the outside water surface.

[0113] (8) The water flow monitoring sensor in the return water tank is working and records the water flow per unit time;

[0114] (9) Keep the working device continuously conducting water-throwing tests for one test cycle, pay attention to the operation of relevant components, and test the stability and reliability of the equipment;

[0115] (10) After the test is completed for the set time, raise the working device and stop the equipment from running;

[0116] (11) Empty the water in the water tank 2 and remove the water tank 2. Then fix the front ramp platform and the rear ramp platform together again.

[0117] (12) After confirming that the ramp 1 is securely fixed, remove the block on the ramp and slowly drive the snow blower down.

[0118] (13) Dismantle all test equipment and transport it to the storage location to complete the snowplow water-throwing test. A schematic diagram of the snowplow water-throwing test is shown below. Figure 6 As shown.

[0119] In this embodiment, water is used instead of snow to test the snow-throwing ability of the snow blower. This testing method is low-cost, economical, and allows for long-term testing. The snow blower is tilted and raised to allow for greater immersion depth, avoiding the need for digging pits and damaging the site. A water return device 3 is included to allow the water thrown by the snow blower to flow back to the original water storage tank 2, preventing water waste. The test device is detachable and easy to store and transport. The width of the ramp 1 is adjustable, making it suitable for hill-climbing tests on other vehicles.

A water return device 3 is configured to allow the sand thrown by the snow-throwing machine to flow back to the original water storage tank 2. The test device is detachable and easy to assemble, making storage and transportation convenient. The width of the ramp is adjustable, making it suitable for climbing tests of other vehicles.

[0146] Example 4

[0147] In this embodiment, the snowplow testing device uses sand instead of snow to test the snowplow. The testing device includes a detachable ramp 1, a water tank 2, and a water return device 3. Figure 1 As shown.

[0148] The ramp 1 includes a front ramp and two rear ramps. The two rear ramps are fixed together by connecting rods. The width of the ramps can be changed by selecting connecting rods of different lengths to accommodate vehicles of different widths. Figure 2 As shown. A movable stop mechanism is provided on the rear ramp. After the vehicle is positioned, the stop protrudes, restricting the vehicle's downward movement. Two front ramps are fixed to the rear ramp with fasteners, forming a complete ramp together. The front ramps can be detached and removed after the vehicle drives onto them, making room for the water tank 2. Vehicles can drive up the ramps. The structural form of the ramp 1 includes, but is not limited to, steel frame, box-type, and modular types.

[0149] The inclined platform 1 can have materials welded onto its surface to enhance friction and prevent vehicle tires from slipping. Preferably, the platform surface is reinforced with welded threaded steel bars to further enhance friction and prevent slippage. Simultaneously, the inclined platform itself can be dimensionally adjusted according to the vehicle's specifications to ensure the safety and reliability of the test. Figure 3 As shown.

[0150] The water storage tank 2 is a container structure capable of accommodating the size of the working device. Preferably, the water storage tank 2 is a rectangular container structure with an opening at the top, facilitating the immersion of the snow blower's working device into the sand. Figure 1 As shown.

[0151] The water return device 3 consists of three parts: a support 301, a water collection tank 302, a return water trough 303, and a water flow monitoring sensor assembly. The support 301 elevates the water collection tank 302, aligning its inlet with the snow-throwing nozzle of the snow blower to collect water thrown by the snow blower. The return water trough 303 allows sand in the water collection tank to flow back to the original water storage tank 2 under gravity for recycling. Figure 3 As shown, the water flow rate is monitored during the sand recirculation process to determine the snow-throwing capacity of the snow blower.

[0152] The testing method for the snow blower described in this embodiment is as follows:

[0153] (1) Select a spacious and flat site, install the test device ramp 1 in a suitable position and fix it firmly, check and clean up any potential risks, and make preparations before the test.

[0154] (2) Drive the snow blower to the test site and reverse it to the set position on the ramp 1. The block mechanism protrudes to restrict the vehicle from sliding down.

[0155] (3) After the vehicle position is fixed, the working device is raised to facilitate the removal of the fasteners of the front ramp and the removal of the device, so as to make room for the water tank 2.

[0156] (4) Place the water storage tank 2 at the original front slope platform position, fill it with sand until the sand reaches the maximum position, and lower the snow blower working device to the lowest position to immerse it in the sand.

[0157] (5) Install the water return device 3 on the side of the water storage tank 2, so that the water collection port of the water collection tank 302 is aligned with the snow throwing port of the snow throwing device, and the water return tank 303 is aligned with the water storage tank 2, and the installation is secure.

[0158] (6) After confirming that all devices are ready and checking that all test devices are installed stably and securely, start the snow blower working device to carry out the water throwing test.

[0159] (7) The working device of the snow blower starts to work. The auger of the snow collection device screws the sand in and throws the sand out along the snow throwing tube through the fan of the snow throwing device. The sand enters the water collection tank 302 and flows back to the original water storage tank 2 along the return water channel 303. During the process, sand is replenished to the water storage tank 2 in time to avoid the sand quantity being reduced due to some sand spilling outside.

[0160] (8) The water flow monitoring sensor in the return water tank 303 is working and records the water flow per unit time;

[0161] (9) Keep the working device continuously conducting water-throwing tests for one test cycle, pay attention to the operation of relevant components, and test the stability and reliability of the equipment;

[0162] (10) After the test is completed for the set time, raise the working device and stop the equipment from running;

[0163] (11) Empty the water in the water tank 2 and remove the water tank 2. Then fix the front ramp platform and the rear ramp platform together again.

[0164] (12) After confirming that the ramp 1 is securely fixed, remove the block on the ramp and slowly drive the snow blower down.

[0165] (13) Dismantle all test equipment and transport it to the storage location to complete the snowplow water-throwing test. A schematic diagram of the snowplow water-throwing test is shown below. Figure 6 As shown.

[0166] In this embodiment, sand is used instead of snow to test the snow-throwing ability of the snow blower. This testing method is low-cost, economical, and allows for long-term testing. The snow blower is tilted and raised to allow for greater immersion depth, avoiding the need for digging pits and damaging the site. A water return device 3 is included to allow the sand thrown by the snow blower to flow back to the original water storage tank 2. The test device is detachable and easy to store and transport. The width of the ramp 1 is adjustable, making it suitable for hill-climbing tests with other vehicles. Water resistance is used to load the working device, testing its stability and reliability under load.

[0238] This embodiment provides a method for testing the snow-throwing ability of a snow blower by using water instead of snow. Common water is used to replace snow to test the snow-throwing ability and operational reliability of the snow blower. The medium used to replace snow is not unique and can be other fluids, including but not limited to water, or granular deposits similar to sand.

[0239] This embodiment provides a test method for loading a working device using the resistance of water, wherein the medium applying the resistance can be other fluids including but not limited to water, or a particle accumulation similar to sand.
