Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of umbrella shielding and relates to an umbrella shielding device for pollution source. Background Art
[0002] As a commonly used protective tool outdoors, umbrellas are widely used in various fields, such as industry, tourism, etc. In the field of environmental testing, pollution source equipment is usually installed outdoors. In order to ensure the reliability of the use of the pollution source equipment and prevent the pollution source equipment from being exposed to the sun and rain to reduce the life of the equipment, umbrellas are usually installed near the pollution source equipment to cover the top of the equipment to play a certain protective role. In the prior art, an umbrella is usually composed of a support frame and a cloth, and the cloth is located on one side of the support frame. In actual use, due to changes in the environment, including but not limited to changes in the angle of sunlight, changes in the angle of raindrops, etc., the umbrella in the prior art cannot take into account the other side, making the umbrella unstable and the protective effect of the equipment poor. Utility Model Content
[0003] The purpose of the utility model is to solve the above problems in the existing technology and propose an umbrella for pollution source equipment. The technical problem to be solved by the utility model is: how to improve the protective effect of the umbrella on the equipment.
[0004] In order to achieve the above purpose, the utility model is implemented through the following technical solutions:
[0005] A shield for pollution source equipment comprises a support frame, characterized in that two rotatable reels are symmetrically arranged on the support frame, and the support frame is also connected to adjustable support arm assemblies corresponding to the two reels respectively, one end of the adjustable support arm assembly is connected to a connecting shaft, a shield cloth is arranged between the reel and the corresponding connecting shaft, one end of the shield cloth is fixed to the reel, and the other end is fixed to the corresponding connecting shaft, and the adjustable support arm assembly always has the tendency to move the connecting shaft away from the corresponding reel and can straighten the shield cloth.
[0006] When it is necessary to shield the pollution source equipment, the drum rotates in a certain direction to release the cloth wound on the drum. The adjustable support arm assembly always has a tendency to move the connecting axis away from the corresponding drum. Therefore, after releasing the cloth, the adjustable support arm assembly drives the connecting axis away from the corresponding drum to unfold the cloth. On the contrary, when it is not necessary to shield the pollution source equipment, the drum rotates in the opposite direction to wind the cloth around the drum. After the drum stops rotating, the cloth is straightened under the adjustment of the adjustable support arm assembly. At this time, since the unfolded length of the cloth does not change, the adjustable support arm assembly is limited, so that the adjustable support arm assembly can no longer drive the connecting axis to move away from the drum. The symmetrically arranged drums allow the pollution source equipment to be placed in the middle of the umbrella. The two drums have two handles for separate control, and the two cloths can be differentially unfolded according to the actual environment, so that the umbrella is suitable for pollution source equipment of different shapes or sizes and provides personalized shielding solutions in different environments, ensuring that the pollution source equipment can be better protected and the shielding effect is improved.
[0007] In the above-mentioned umbrella of a pollution source device, the adjustable support arm assembly is provided at both ends of the two reels, and the adjustable support arm assembly includes a first arm and a second arm, and the two ends of the connecting shaft are connected to one end of the two corresponding second arms, and the other end of the second arm is elastically hinged to one end of the first arm, and an elastic member with elastic restoring force is connected between the second arm and the first arm, and the other end of the first arm is rotatably connected to the support frame. The hinge connection between the first arm and the second arm allows the umbrella to unfold the cloth freely as the reel rotates, and has high flexibility, and cooperates with the rotation of the reel to achieve stepless adjustment, so that the expansion and contraction of the umbrella are both linear movements, and the umbrella can be more smoothly expanded and contracted. The elastic member can be an elastic rubber band, one end of which is fixed on the first arm, and the other end is fixed on the second arm. When the first arm and the second arm are folded, the elastic rubber band is stretched and has an elastic restoring force. When the reel releases the shade cloth, the elastic rubber band causes the first arm and the second arm to expand to a taut state of the umbrella under the action of the elastic restoring force. A preferred solution is to arrange the rubber band inside the first arm and the second arm, and the two ends are respectively connected to the end of the first arm and the end of the second arm. It is a prior art to realize elastic hinge of the first arm and the second arm by means of an elastic rubber band, and this description is intended to more clearly illustrate this solution.
[0008] In the above-mentioned umbrella for pollution source equipment, the shading cloth is located above the first arm and the second arm. The first arm and the second arm are in a hinged connection relationship, and the flexibility of the connection is of great significance to the sensitivity of the adjustable support arm assembly. Therefore, the shading cloth is arranged above the first arm and the second arm to protect the connection between the first arm and the second arm, avoid the connection between the first arm and the second arm from being exposed to the sun and rain, improve the practicality of the umbrella, and ensure the life of the umbrella.
[0009] In the above-mentioned umbrella for pollution source equipment, the outer angle between the first arm and the second arm is smaller than the inner angle between the first arm and the second arm. The outer angle between the first arm and the second arm is smaller than the inner angle between the first arm and the second arm, so that the adjustable support arm assembly is protected by the cloth when the umbrella is unfolded and retracted, further ensuring the life of the adjustable support arm assembly.
[0010] In the above-mentioned umbrella for pollution source equipment, the support frame includes two relatively vertically arranged support rods, a horizontally arranged long strip-shaped connecting plate is fixed between the top ends of the two support rods, two adjacent fixed plates are fixed at both ends of the connecting plate, and the two ends of the two reels are rotatably connected to the corresponding fixed plates. Through the cooperation of the four fixed plates and the connecting plate, the reel and the fixed plate have a large contact area, and the reel is clamped in the middle by the two fixed plates, so that the reliability and stability of the reel connection are improved.
[0011] In the above-mentioned umbrella for pollution source equipment, the connecting plate is located above the two reels. The reels are rotatably connected to the fixed plate, and the flexibility of the connection is of great significance to the sensitivity of the expansion and contraction of the umbrella. Therefore, the connecting plate located above the two reels can also play a protective role and ensure the life of the umbrella.
[0012] In the above-mentioned umbrella for pollution source equipment, the four first arms are respectively hinged on the corresponding fixing plate. When the first arm and the second arm are retracted or extended, the angle between the first arm and the second arm changes, and the connection method of hinged connection on the fixing plate is more in line with the dynamic change of the first arm, thereby ensuring the stable use of the umbrella.
[0013] In the above-mentioned umbrella for pollution source equipment, both of the two support rods have oblique support rods arranged obliquely downward, and the two oblique support rods are arranged toward the same side. The arrangement of the oblique support rods increases the stability of the umbrella.
[0014] Compared with the prior art, the advantages of the utility model are: the symmetrically arranged reels allow the pollution source equipment to be placed in the middle of the umbrella, and the two reels have two handles for separate control, so that the two shade cloths can be unfolded differentially according to the actual environment, making the umbrella suitable for pollution source equipment of different shapes or sizes and providing personalized shielding solutions in different environments, ensuring that the pollution source equipment can be better protected and improving the shielding effect.

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to the following embodiments.
[0020] Depend on Figures 1 to 3 It can be seen that an umbrella for pollution source equipment includes a support frame 1, on which two rotatable reels 2 are symmetrically arranged, and the support frame 1 is also connected to adjustable support arm assemblies 3 corresponding to the two reels 2 respectively, one end of the adjustable support arm assembly 3 is connected to a connecting shaft 4, a shade cloth 5 is provided between the reel 2 and the corresponding connecting shaft 4, one end of the shade cloth 5 is fixed on the reel 2, and the other end is fixed on the corresponding connecting shaft 4, and the adjustable support arm assembly 3 always has a tendency to horizontally move the connecting shaft 4 away from the corresponding reel 2.
[0021] Both ends of the two reels 2 are provided with an adjustable support arm assembly 3, which includes a first arm 31 and a second arm 32. Both ends of the connecting shaft 4 are connected to one end of the corresponding two second arms 32, and the other end of the second arm 32 is elastically hinged to one end of the first arm 31, and the other end of the first arm 31 is rotatably connected to the support frame 1. The elastic hinge between the first arm 31 and the second arm 32 enables the shade cloth 5 to be freely unfolded with the rotation of the reel 2, which has high flexibility, and realizes stepless adjustment in conjunction with the rotation of the reel 2, so that the unfolding and retraction of the shade cloth are both linear movements, and the shade cloth can be unfolded and retracted more smoothly. The elastic member can be an elastic rubber band, one end of which is fixed on the first arm 31, and the other end is fixed on the second arm 32. When the first arm 31 and the second arm 32 are folded, the elastic rubber band is stretched and has an elastic reset force. When the reel releases the shade cloth 5, the elastic rubber band, under the action of the elastic reset force, causes the first arm 31 and the second arm 32 to unfold to a taut umbrella state. It is a prior art to realize the elastic connection of the first arm 31 and the second arm 32 by means of an elastic rubber band. This description is for the purpose of more clearly explaining the present solution, but other elastic parts are not excluded as elastic members. It is preferred that the rubber band is arranged inside the first arm and the second arm, and the two ends are respectively connected to the end of the first arm and the end of the second arm.
[0022] The first arm 31 and the second arm 32 are hingedly connected, and the flexibility of the connection is of great significance to the sensitivity of the adjustable support arm assembly 3. Therefore, the shade cloth 5 is arranged above the first arm 31 and the second arm 32 to protect the connection between the first arm 31 and the second arm 32. The outer angle between the first arm 31 and the second arm 32 is smaller than the inner angle between the first arm 31 and the second arm 32, thereby preventing the connection between the first arm 31 and the second arm 32 from being exposed to the sun and rain, thereby improving the practicability of the umbrella and ensuring the life of the umbrella.
[0023] The support frame 1 includes two relatively vertically arranged support rods 11, a horizontally arranged long strip-shaped connecting plate 12 is fixed between the top ends of the two support rods 11, two adjacent fixed plates 13 are fixed to the two ends of the connecting plate 12, the two ends of the two reels 2 are rotatably connected to the corresponding fixed plates 13, and the four first arms 31 are hinged to the corresponding fixed plates 13. Through the cooperation of the four fixed plates 13 and the connecting plate 12, the reel 2 and the fixed plate 13 have a large contact area, and the reel 2 is sandwiched in the middle by the two fixed plates 13, so that the reliability and stability of the connection of the reel 2 are improved. The reel 2 is rotatably connected to the fixed plate 13, and the flexibility of the connection is of great significance to the sensitivity of the expansion and contraction of the umbrella. Therefore, the connecting plate 12 located above the two reels 2 can also play a protective role and ensure the life of the umbrella.
[0024] The two support rods 11 are provided with oblique support rods 14 arranged obliquely downward, and the two oblique support rods 14 are arranged toward the same side. The arrangement of the oblique support rods 14 increases the stability of the umbrella.
[0025] In the present umbrella, the reel 2 can be driven to rotate by an existing driving method. In the embodiment, the present embodiment is explained by driving the worm by the handle and driving the reel 2 to rotate by the transmission member. Specifically, when it is necessary to shield the pollution source equipment, the handle is used to drive the worm to rotate, and the worm drives the reel 2 to rotate through the transmission member, and the cover cloth 5 wound on the reel 2 is released. At this time, since the adjustable support arm assembly 3 always has a tendency to unfold, the adjustable support arm assembly 3 unfolds and drives the cover cloth 5 to unfold after the cover cloth 5 is released; on the contrary, when it is not necessary to shield the pollution source equipment, the handle is also used to drive the worm to rotate and drive the reel 2 to rotate in the opposite direction through the transmission member, so that the cover cloth 5 is wound on the reel 2. In actual use, an appropriate driving method can be selected to drive the reel 2 according to the needs. After the reel 2 stops rotating, the cover cloth 5 is straightened under the adjustment of the adjustable support arm assembly 3. At this time, since the unfolded length of the cover cloth will not change, the adjustable support arm assembly 3 is limited, so that the adjustable support arm assembly 3 can no longer drive the connecting shaft 12 to move away from the reel 2.
[0026] In the utility model, the symmetrically arranged reels 2 allow the pollution source equipment to be placed in the middle of the umbrella, and the two reels 2 have two handles for respective control, so that the two shade cloths 5 can be differentially unfolded according to the actual environment, making the umbrella suitable for pollution source equipment of different shapes or sizes and providing personalized shielding solutions in different environments, thereby ensuring that the pollution source equipment can be better protected and improving the shielding effect.
