Description

Technical Field

[0001] The utility model relates to the technical field of voltage sensors, in particular to a voltage sensor with a waterproof function. Background Technique

[0002] With the development of more and more new technologies, voltage sensors have also been further developed and applied. A voltage sensor refers to a sensor that can sense the measured voltage and convert it into an available output signal. In various automatic detection and control systems, it is often necessary to track and collect AC and DC voltage signals with high-speed changes, and perform spectral analysis on relatively complex voltage waveforms.

[0003] Chinese Patent with the authorization publication number of CN220894397U discloses an isolated voltage sensor, which includes a housing and a signal processing module arranged in the housing; an input module and an output module are respectively arranged on the front and rear sides of the housing, and shock-absorbing structures are arranged on both the left and right sides of the housing. The shock-absorbing structure includes a shock-absorbing part, a connecting part and a clamping part; the shock-absorbing part includes a lifting block and a plurality of shock-absorbing springs, and the shock-absorbing springs are symmetrically arranged around the front, rear, upper and lower sides of the lifting block and are respectively connected to the inner walls of the front, rear, upper and lower sides of the housing; the connecting part is arranged on the side of the lifting block close to the signal processing module, and the clamping part is arranged on the side of the connecting part close to the signal processing module; by arranging the signal processing module in the housing, the utility model can improve the external force that the voltage sensor can withstand, and by arranging the shock-absorbing structure to connect the signal processing module, it can effectively reduce the vibration of the signal processing module, avoid damage to the electronic components in the signal processing module after collision, and improve the shock-proof effect.

[0004] Although the above-mentioned voltage sensor can effectively reduce the vibration of the signal processing module by arranging the shock-absorbing structure to connect the signal processing module, avoid damage to the electronic components in the signal processing module after collision, and improve the shock-proof effect, the voltage sensor usually needs to be heat-dissipated during use. Usually, exposed through holes are arranged on the housing for the outflow of hot air. However, the direct exposure of the through holes will cause the entry of external dust and water vapor, which is not conducive to the protection of internal components. For this reason, we propose a voltage sensor with a waterproof function. Content of the Utility Model

[0005] The purpose of the utility model is to provide a voltage sensor with a waterproof function to solve the problem proposed in the above background technique that since the voltage sensor usually needs to be heat-dissipated during use, exposed through holes are usually arranged on the housing for the outflow of hot air. However, the direct exposure of the through holes will cause the entry of external dust and water vapor, which is not conducive to the protection of internal components.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A voltage sensor with a waterproof function, comprising:

[0007] A base, above which a sensor housing is installed, and several cooling fans are installed on the top of the sensor housing. On both sides of the outer wall of the sensor housing, heat dissipation grooves are provided, and protective baffles are installed outside the heat dissipation grooves. Above the protective baffles, telescopic push rods are connected;

[0008] Heat dissipation through holes, which are opened at the bottom of the sensor housing. Below the heat dissipation through holes, a heat conducting plate is connected, and heat dissipation fins are installed on the lower end surface of the heat conducting plate;

[0009] An encapsulation backplane, which is installed at one end of the sensor housing. A sealing rubber strip is provided at the connection between the encapsulation backplane and the sensor housing. Fixed blocks are connected to both sides of the encapsulation backplane.

[0010] Preferably, the cooling fan further includes:

[0011] A protective cover, which is installed outside the cooling fan. Above the protective cover, a breathable net is installed, and the breathable net is a hollow mesh structure.

[0012] Preferably, the cooling fans are evenly distributed along the top of the sensor housing, and the heat dissipation grooves are symmetrically distributed about the vertical center line of the sensor housing.

[0013] Preferably, the heat dissipation through holes are evenly distributed, and the positions of the heat dissipation through holes correspond to those of the heat conducting plate, and the heat dissipation fins are evenly distributed along the lower end surface of the heat conducting plate.

[0014] Preferably, a semi-surrounding structure is formed between the protective baffle and the heat dissipation groove, and a telescopic structure is formed between the telescopic push rod and the protective baffle.

[0015] Preferably, a sealing structure is formed between the encapsulation backplane and the sensor housing through the sealing rubber strip, and the encapsulation backplane is relatively fixed to the sensor housing through the fixed blocks and bolts.

[0016] Compared with the prior art, the present utility model provides a voltage sensor with a waterproof function, having the following beneficial effects:

[0017] The utility model can protect the heat dissipation slots through the protection baffle, thereby avoiding the entry of dust and water vapor. The telescopic push rod can drive the protection baffle to move vertically, so that when a large amount of heat dissipation is required, the heat dissipation slots can be opened. At this time, since there is more hot air transmitted from the inside of the housing to the outside, an outward air flow is formed, so it is difficult for external dust and water vapor to enter, avoiding the problem that the voltage sensor usually needs heat dissipation treatment during use. Usually, exposed through holes are provided on the housing for the outflow of hot air. However, the direct exposure of the through holes will cause the entry of external dust and water vapor, which is not conducive to the protection of internal components.

The cooling fans 3 are evenly distributed along the top of the sensor housing 2, and the heat dissipation grooves 6 are symmetrically distributed about the vertical center line of the sensor housing 2; the cooling fans 3 can blow air into the sensor housing 2, and at the same time, the air circulation inside and outside the sensor housing 2 can be promoted through the heat dissipation grooves 6; a telescopic push rod 11 is connected above the protective baffle 7; a semi-surrounding structure is formed between the protective baffle 7 and the heat dissipation groove 6, and a telescopic structure is formed between the telescopic push rod 11 and the protective baffle 7; the protective baffle 7 can protect the heat dissipation groove 6, thereby preventing the entry of dust and water vapor. The telescopic push rod 11 can drive the protective baffle 7 to move vertically, so that when a large amount of heat dissipation is required, the heat dissipation groove 6 can be opened. At this time, since there is more hot air transferred from the inside of the housing to the outside, an outward air flow is formed, so it is difficult for external dust and water vapor to enter; a protective cover 4, which is installed outside the cooling fan 3, and a ventilation net 5 is installed above the protective cover 4, and the ventilation net 5 is a hollow mesh structure; the protective cover 4 can protect the cooling fan 3, and the heat dissipated by the cooling fan 3 can be discharged through the ventilation net 5.

[0024] Please refer to Figure 1 and 3 , a voltage sensor with a waterproof function, comprising: heat dissipation through holes 8, which are opened at the bottom of the sensor housing 2, a heat conduction plate 10 is connected below the heat dissipation through holes 8, and heat dissipation fins 9 are installed on the lower end surface of the heat conduction plate 10; the heat dissipation through holes 8 are evenly distributed, and the positions of the heat dissipation through holes 8 correspond to those of the heat conduction plate 10, and the heat dissipation fins 9 are evenly distributed along the lower end surface of the heat conduction plate 10; the heat dissipation through holes 8 can facilitate the conduction of the hot air in the sensor housing 2 to the heat conduction plate 10, and the heat can be transferred to the heat dissipation fins 9 through the heat conduction plate 10, so as to achieve a heat dissipation effect; a packaging back plate 12, which is installed at one end of the sensor housing 2, a sealing strip 13 is provided at the connection between the packaging back plate 12 and the sensor housing 2, and fixing blocks 14 are connected to both sides of the packaging back plate 12; the packaging back plate 12 forms a sealed structure with the sensor housing 2 through the sealing strip 13, and the packaging back plate 12 is relatively fixed to the sensor housing 2 through the fixing blocks 14 and bolts; the sealing performance between the packaging back plate 12 and the sensor housing 2 can be improved through the sealing strip 13, and the mutual disassembly and assembly of the packaging back plate 12 and the sensor housing 2 can be facilitated through the fixing blocks 14.

[0025] Working principle: When using this waterproof voltage sensor, first, the sealing strip 13 can improve the sealing performance between the encapsulation backplane 12 and the sensor housing 2, and the fixing block 14 facilitates the mutual disassembly and assembly of the encapsulation backplane 12 and the sensor housing 2; second, the protective cover 4 can protect the cooling fan 3, and at the same time, the breathable net 5 facilitates the discharge of the heat dissipated by the cooling fan 3, and the protective baffle 7 can protect the heat dissipation slot 6, thereby preventing the entry of dust and water vapor; then, during the use process, the cooling fan 3 is started, and the cooling fan 3 blows air into the sensor housing 2. At the same time, the heat dissipation slot 6 can promote the air circulation inside and outside the sensor housing 2. At the same time, the heat dissipation through-hole 8 facilitates the conduction of the hot air inside the sensor housing 2 to the heat conduction plate 10, and the heat conduction plate 10 can transfer the heat to the heat dissipation fins 9, thereby achieving a heat dissipation effect; finally, when a large amount of heat dissipation is required, the telescopic push rod 11 is started, and the telescopic push rod 11 drives the protective baffle 7 to move in the vertical direction, so that the heat dissipation slot 6 can be opened. At this time, since there is more hot air transferred from the inside of the housing to the outside, an outward air flow is formed, so it is difficult for external dust and water vapor to enter. This is the working principle of this waterproof voltage sensor.
