Description

Technical Field

[0001] The utility model belongs to the field of ventilation and heat dissipation of generator sets, and particularly relates to an intelligent sand-proof air intake device for power generation equipment. Background Art

[0002] At present, for general emergency charging equipment, vehicle-mounted power supplies and other equipment, the matching generator sets are usually suitable for working conditions with relatively good environment, and lack sand-proof protection devices. However, in practical applications, environments with wind and sand may be encountered.

[0003] The technical problem existing in the prior art is that since there is no protection at the air inlet of an ordinary unit, when the unit operates, a large amount of wind and sand will be sucked into the cabinet by the cooling fan of the unit. The accumulation of a large amount of wind and sand affects the normal operation of the engine, generator and heat dissipation water tank of the unit, and is difficult to be found in time, which causes the unit to fail to generate power normally and even damages the equipment. Summary of the Utility Model

[0004] The object of the present utility model is to provide an intelligent sand-proof air intake device for power generation equipment, which solves the problem that the air inlet of an ordinary generator set in the prior art does not have a sand-proof function, thereby achieving simple installation, convenient maintenance, high-quality and efficient sand-proof performance, and can intelligently monitor the air intake effect of the device in real time, remind a user to maintain the filter device in time, avoid huge losses to the equipment, and save operation and maintenance costs and workload.

[0005] In order to achieve the above object, the utility model adopts the following technical solution: An intelligent sand-proof air intake device for power generation equipment comprises a front surround air intake plate support, wherein a plurality of metal plate filters with the same structure are embedded in the front surround air intake plate support, a first air intake hopper and a second air intake hopper are arranged on the inner side of the front surround air intake plate support, the opening of the first air intake hopper faces upward, the opening of the second air intake hopper faces downward, and the first air intake hopper and the second air intake hopper form a U-shaped air intake channel.

[0006] Further, an air pressure difference sensor is arranged above the second air intake hopper, the air pressure difference sensor is provided with a front air intake monitoring pipe and a rear air intake monitoring pipe, the front air intake monitoring pipe passes through the front surround air intake plate support and extends outward to an external air intake position, and the rear air intake monitoring pipe extends downward into the second air intake hopper.

[0007] Further, there are 3 metal plate filters, and the metal plate filters are arranged in a filter fixing frame through filter fixing pressing plates.

[0008] Further, the front surround air intake plate support is connected with the filter fixing pressing plate by bolts.

[0009] Furthermore, the wind pressure differential sensor uses a dedicated pressure sensor chip with an ultra-low range.

[0010] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: 1. The metal plate filter is mounted on the front air inlet plate bracket via a filter fixing plate. The filter fixing plate has fixing bolts at both ends and the top for fixing the metal plate filter. The metal plate filter can be easily disassembled and assembled by simply loosening or tightening the fixing bolts, which facilitates cleaning and maintenance of the metal plate filter.

[0011] 2. Metal plate filters can effectively filter sand and dust. The filter media is made of multiple layers of corrugated expanded stainless steel mesh arranged in a cross-over pattern. The multiple layers of metal mesh are arranged with different densities and pore sizes, which causes the air to change its flow direction multiple times when passing through the filter, increasing its dust collection capacity and efficiency. It has a long service life, can be repeatedly cleaned, and has high economic performance.

[0012] 3. The first air inlet faces upward and the second air inlet faces downward, forming a double-layer air inlet structure, which extends the air intake path. On the one hand, it can effectively prevent water and sand from entering, and on the other hand, it can reduce air intake noise.

[0013] 4. The wind pressure differential sensor has a robust and flexible housing structure, excellent long-term stability, minimal impact from position, and small long-term drift. It features built-in temperature compensation, enabling easy installation and measurement in various environments. Utilizing a dedicated pressure sensor chip with an ultra-low range, it exhibits high sensitivity for measuring minute pressures. It monitors the inlet pressure difference before and after the metal plate filter in real time. Once the inlet pressure difference reaches a specified value, indicating that the metal plate filter has accumulated a large amount of sand and dust, and the airflow is insufficient for unit operation, the wind pressure differential sensor sends a signal to the unit controller. The unit controller promptly issues an alarm signal, reminding the user to maintain the filter in a timely manner, avoiding significant equipment damage and saving on operation and maintenance costs and workload.

[0018] 2. For example Figures 1 to 4 As shown, this utility model provides an embodiment: an intelligent sand-proof air intake device for a power generation equipment, including a front air intake plate bracket 1. The front air intake plate bracket 1 is embedded with a plurality of metal plate filters 2 with the same structure. A first air intake hopper 3 and a second air intake hopper 4 are arranged on the inner side of the front air intake plate bracket 1. The opening of the first air intake hopper 3 faces upward and the opening of the second air intake hopper 4 faces downward. The first air intake hopper 3 and the second air intake hopper 4 form a U-shaped air intake channel.

[0019] The wind pressure differential sensor 5 features a robust and compact housing structure, excellent long-term stability, minimal influence from position, and small long-term drift. It incorporates temperature compensation, enabling easy installation and measurement in various environments. Furthermore, the wind pressure differential sensor 5 utilizes a dedicated pressure sensor chip with an ultra-low range, exhibiting high sensitivity for measuring minute pressures. It monitors the inlet pressure difference before and after filtration by the metal plate filter 2 in real time. Once the inlet pressure difference reaches a specified value, it indicates that the metal plate filter 2 has accumulated a large amount of sand and dust, and the airflow is insufficient for unit operation. The wind pressure differential sensor 5 sends a signal to the unit controller, which promptly issues an alarm signal, reminding the user to maintain the filter in a timely manner to avoid significant equipment damage and save on operation and maintenance costs and workload.

[0020] The front air intake plate bracket 1 is bolted to the filter fixing plate 8. The metal plate filter 2 can be easily disassembled for cleaning and maintenance simply by unscrewing the fixing bolts.

[0021] The first air intake hopper 3 has its opening facing upwards, and the second air intake hopper 4 has its opening facing downwards, forming a double-layer air intake structure. This extends the air intake path, effectively preventing water and sand from entering the air, and also reducing air intake noise.

[0022] The metal plate filter 4 filters wind and sand. Its filter media is made of multiple layers of corrugated expanded stainless steel mesh arranged in a cross-over pattern. The multiple layers of metal mesh are arranged with different densities and pore sizes, which causes the air to change its flow direction multiple times when passing through the filter, increasing its dust collection capacity and efficiency. It has low resistance, long service life, can be repeatedly cleaned, and has high economic performance.

[0023] Working Principle: This utility model provides an intelligent sand-proof air intake device for power generation equipment, solving the problem that the air intake of ordinary generator sets in the prior art does not have sand-proof function. A metal plate filter 2 filters sand and dust. After air enters the first air intake hopper 3, it flows into the second air intake hopper 4 from the opening of the first air intake hopper 3, and finally flows out from the opening of the second air intake hopper 4. A wind pressure differential sensor 5 is equipped with a pre-intake monitoring pipe 6 and a post-intake monitoring pipe 7. The pre-intake monitoring pipe 6 monitors the external air intake pressure, and the post-intake monitoring pipe 7 monitors the air intake pressure after filtration by the metal plate filter 2. Once the air intake pressure difference reaches a specified value, the wind pressure differential sensor 5 sends a signal to the unit controller. The unit controller promptly issues an alarm signal to remind the user to maintain the filter device in a timely manner, avoiding significant equipment damage and saving operation and maintenance costs and workload.
