Description

Technical Field

[0001] This utility model relates to the field of level transmitters, specifically a level transmitter housing structure with rainproof effect. Background Technology

[0002] A level transmitter is an instrument used to measure the level or changes in the level of liquids or solids. It typically converts the measured level information into a standard electrical signal (such as 4-20mA, 0-10V, etc.) for processing and display by the control system. Level transmitters are widely used in various industries, such as chemical, petroleum, food, pharmaceutical, and environmental protection, for monitoring and controlling the storage, transportation, and handling of liquids or solids.

[0003] Existing different types of level transmitters are suitable for different application scenarios. When used outdoors, because the housing of the level transmitter is mostly square, rainwater is prone to accumulate on the outer wall of the level transmitter in rainy weather. Over time, rainwater will spread on the outer wall of the housing and seep into the interior of the level transmitter through the gaps in the housing, thus affecting the overall operation and reducing the overall service life.

[0004] In conclusion, when level transmitters operate outdoors in rainy weather, the accumulation of rainwater can easily affect their overall operation and reduce their service life. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a rainproof housing structure for a level transmitter, in order to solve the technical problem that when the level transmitter is working outdoors in rainy weather, the accumulation of rainwater can easily affect the overall operation of the level transmitter and reduce its overall service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a level transmitter housing structure with rainproof effect, comprising an outer shell and a drainage tank, wherein the drainage tank is symmetrically arranged on both sides of the outer shell, an array of drainage grooves is provided on the top of the outer shell, the end face of which is inclinedly provided with a guide surface, and one end of the drainage groove is provided with an accumulation groove on the guide surface, the top of the drainage tank is provided with a seepage groove, wherein the seepage groove is provided with a water inlet hole, and a drainage hole that cooperates with it is provided at the bottom of the drainage tank.

[0007] By adopting the above technical solution, rainwater is collected through drainage channels and then quickly discharged into the collection channels. The collection channels act as a guide for the rainwater, effectively preventing large-scale spread of rainwater on the outer shell. Then, the rainwater flows into the drainage box through the wedge-shaped blocks and is directly discharged into the drainage box through the surrounding flow channel. This drainage method greatly reduces the contact area of ​​rainwater on the outer shell.

[0008] The present invention is further configured such that a wedge-shaped block is provided in the seepage groove, and the wedge-shaped block is inclined downward at one end of the water inlet hole.

[0009] Preferably, the wedge-shaped block causes rainwater passing through the guide surface to flow towards the inlet hole, thus preventing rainwater from accumulating in the infiltration groove.

[0010] The present invention is further configured such that a surrounding flow channel is provided inside the drainage tank, wherein one end of the surrounding flow channel is connected to the water inlet hole, and a sealing plate is rotatably arranged inside the surrounding flow channel.

[0011] Preferably, the flow rate of rainwater in the drainage box is accelerated by the action of the surrounding flow channel. When the rainwater is discharged from the drainage box through the surrounding flow channel, it is ensured that the rainwater will not stay and accumulate at the bottom of the drainage box, thereby improving the overall drainage efficiency. At the same time, a sealing plate is installed in the surrounding flow channel. When the amount of rainwater at one end of the surrounding flow channel reaches a certain amount, the sealing plate opens, so that when the amount of rainwater is small, it can be accumulated at one end of the surrounding flow channel, effectively preventing the rainwater from slowly draining out of the drainage box.

[0012] The present invention is further configured such that a torsion spring is connected between the sealing plate and the surrounding flow channel, and a sealing ring is provided on the outer wall of the sealing plate.

[0013] Preferably, under the action of the torsion spring, a certain amount of rainwater is accumulated at one end of the flow channel before being discharged outward, which effectively prevents the situation where the flow rate of a small amount of rainwater is insufficient when it is discharged, which would cause the rainwater to spread at the drainage hole.

[0014] The present invention is further configured such that the outer wall of the guide surface is smooth, and a chamfer is provided at the top of the seepage groove to match it.

[0015] Preferably, the smooth surface prevents rainwater from accumulating on the guide surface and reduces the spread of rainwater on the outer casing, while the chamfered angle prevents rainwater passing through the guide surface from seeping between the drainage tank and the outer casing.

[0016] The present invention is further configured such that the inner wall of the drainage trough is semi-arc-shaped, the accumulation trough itself is semi-circular, and an opening is provided at the flow guiding surface.

[0017] Preferably, the semi-circular shape ensures that rainwater flows to the bottom of the drainage channel, and the rainwater in the accumulation channel flows through the opening to guide the flow surface.

[0018] The present invention is further configured such that the drainage tank is provided with a bolt assembly, wherein the outer shell is provided with a threaded hole that mates with it.

[0019] Preferably, the drain tank is detachably mounted on the outer casing by means of bolt assembly and threaded hole, which facilitates subsequent replacement and maintenance by staff and effectively prevents blockage of the surrounding flow channel.

[0020] The present invention is further configured such that the circumferential angle at the corner of the circumferential flow channel is 20°-40°.

[0021] Preferably, a certain tilt angle ensures that the flow velocity of rainwater through the surrounding channel does not decrease excessively, thereby increasing the flow velocity of rainwater within the surrounding channel.

[0022] The present invention is further configured such that the bottom of the drainage box at the drainage hole is smooth.

[0023] Preferably, the smooth surface prevents rainwater from accumulating at the bottom of the drainage box as it drains through the drain hole.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model has a drainage groove on the top of the shell. In rainy weather, rainwater will flow through the drainage groove to the flow guide surface, and then flow into the drainage box under the action of the wedge block. It will then be discharged directly into the drainage box through the surrounding flow channel. This drainage method greatly reduces the contact area of ​​rainwater on the shell, prevents rainwater from spreading on the shell, and shortens the residence time of rainwater on the shell, effectively preventing rainwater from seeping into the shell.

[0026] 2. This utility model features a surrounding flow channel within the drainage tank. This channel accelerates the flow of rainwater within the tank, preventing it from accumulating at the bottom and improving overall drainage efficiency. Furthermore, a sealing plate within the channel opens when a certain amount of rainwater accumulates at one end, effectively preventing the slow discharge of rainwater from the drainage tank.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] First embodiment:

[0038] Please see Figures 1-6 The illustrated level transmitter housing structure with rainproof effect includes a housing 1, a drainage tank 2, a sliding mechanism, a flow guiding mechanism, and a drainage mechanism. In rainy weather, rainwater flows towards the top of the housing 1. An array of drainage channels 5 is provided on the top of the housing 1, with flow guiding surfaces 10 inclined at their ends. One end of each drainage channel 5 has a collection groove 6 located on the flow guiding surface 10. The rainwater on the top of the housing 1 flows into the drainage channels 5 and then into the collection groove 6 under the influence of the flow guiding surface 10. This process effectively guides the rainwater and prevents large amounts of rainwater from accumulating on the housing 1. In the case of area diffusion, some rainwater will accumulate in the accumulation trough 6. The accumulation trough 6 itself plays a role in guiding the rainwater, which will be discharged into the drainage box 2 under the action of the guide surface 10. A seepage trough 3 is provided on the top of the drainage box 2, in which a water inlet hole 7 is opened, and a drainage hole is provided at the bottom of the drainage box 2 to cooperate with it. Then, the rainwater is directly discharged into the drainage box 2 through the drainage hole. This drainage method greatly reduces the contact area of ​​rainwater on the outer shell 1, prevents rainwater from spreading on the outer shell 1, and shortens the residence time of rainwater on the outer shell, effectively preventing rainwater from seeping into the outer shell 1.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 2A wedge-shaped block 4 is provided in the infiltration trough 3, and the wedge-shaped block 4 is inclined downward at one end of the water inlet hole 7. Under the action of the wedge-shaped block 4, the rainwater passing through the guide surface 10 will flow to the water inlet hole 7, which prevents the rainwater from accumulating in the infiltration trough 3.

[0040] Second embodiment:

[0041] Please see Figure 5 The illustrated level transmitter housing structure is similar to that of Embodiment 1. The drainage tank 2 contains a surrounding flow channel 8, one end of which is connected to the water inlet 7. A sealing plate 9 is rotatably mounted within the surrounding flow channel 8. The surrounding flow channel 8 accelerates the flow of rainwater within the drainage tank 2, ensuring that rainwater does not accumulate at the bottom of the drainage tank 2 as it drains through the channel, thus improving overall drainage efficiency. Simultaneously, the sealing plate 9 opens when a certain amount of rainwater accumulates at one end of the channel, preventing the accumulation of small amounts of rainwater at one end and effectively preventing slow drainage from the drainage tank 2.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A torsion spring connects the sealing plate 9 to the surrounding flow channel 8, and a sealing ring is provided on the outer wall of the sealing plate 9. Under the action of the torsion spring, a certain amount of rainwater is accumulated at one end of the surrounding flow channel 8 before it is discharged outward, which effectively prevents the situation where the flow rate is insufficient when a small amount of rainwater is discharged, which would cause rainwater to spread at the drainage hole. At the same time, the sealing ring prevents rainwater leakage in the surrounding flow channel 8.

[0043] In practical operation, this invention works as follows: During rainy weather, rainwater falls to the top of the outer casing 1 and is then collected through the drainage channel 5 before being quickly discharged into the accumulation channel 6. The accumulation channel 6 acts as a guide for the rainwater, effectively preventing large-scale spread of rainwater on the outer casing 1. When rainwater seeps out of the accumulation channel 6, it is discharged into the drainage tank 2 under the action of the guide surface 10, enters the drainage tank 2 through the water inlet 7, and then slides out of the drainage tank 2 through the flow channel 8. The flow channel 8 ensures that the rainwater reaches a certain flow rate when discharged, preventing rainwater from accumulating at the bottom of the drainage tank 2 and improving the overall drainage efficiency.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
