Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection equipment, in particular to a water quality detection timing water bath device. Background Art

[0002] In water quality testing, there are test steps that require the test solution to be placed in a water bath for a long time. For example, when making arsenic and mercury test solutions, nitric acid and hydrochloric acid need to be added to the sample water, which is then placed in a water bath and heated for 2 hours, and finally taken out of the water bath and left to stand for 5 hours. Due to the long water bath time, it is impossible for the test personnel to monitor the water bath process for a long time. If the preset water bath time is missed and then taken out, it may affect the test results, and even the arsenic and mercury test solution needs to be prepared again, resulting in unnecessary waste of time. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a timed water bath device for water quality testing, which can take the sample containers that have completed the water bath out of the water bath pot according to the preset water bath time, thereby avoiding unnecessary negative effects caused by water bath timeout.

The support structure is detachably provided with a sample rack, and the sample rack is used to place a number of sample bottles; the support structure is connected to a lifting drive device that drives itself to rise and fall, and a timing module is electrically connected to the lifting drive device through a control module.

[0005] Furthermore, the mounting frame includes a bracket body placed on the port surface of the water bath mechanism, the middle part of the bracket body is hollowed out to provide a movable interval for the lifting and lowering of the supporting structure, a plurality of lifting and sliding carriers are fixed above the bracket body, and each lifting and sliding carrier is provided with a supporting structure corresponding to the lifting and lowering cooperation.

[0006] Furthermore, the support structure includes a lifting platform that is slidably matched with the lifting and sliding carrier, and two clamping units are relatively slidably arranged on the support surface of the lifting platform. The two clamping units are connected by an adjustment structure, and the two clamping units are relatively clamped on both sides of the sample rack.

[0007] Furthermore, a heat insulation plate is provided between the support body and the bath mechanism port surface for transverse sliding movement.

[0008] Furthermore, the upper and lower limit positions of the lifting and sliding carrier are respectively provided with sensing modules for sensing the limit position in place state of the lifting platform, and the two sensing modules are electrically connected to the timing module through the control module.

[0009] Furthermore, the heat insulation board is connected to an opening and closing driving device for driving it to slide laterally, and the sensing module on the upper side is electrically connected to the opening and closing driving device through a control module.

[0010] Beneficial effects: The utility model provides a timing water bath device for water quality testing. A sample rack containing samples is placed in or taken out of a water bath pot through a lifting support structure. The time for placing the samples in the water bath pot is timed by a timing module. The lifting and lowering of the support structure is controlled according to a preset water bath time, thereby preventing the samples from being heated in a water bath for too long due to being forgotten, thereby avoiding unnecessary negative effects caused by water bath timeout. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Attached Figure 1 The utility model is a schematic structural diagram of an embodiment. DETAILED DESCRIPTION

[0012] The utility model is further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The water quality detection timing water bath device comprises a mounting frame 1, wherein the mounting frame 1 is erected relative to the port of a water bath mechanism 2, and the mounting frame 1 is provided with a support structure 3 for lifting and lowering, and a sample rack 4 is detachably provided on the support structure 3, and the sample rack 4 is used to place a plurality of sample bottles 5; the support structure 3 is connected to a lifting drive device 6 for driving itself to rise and fall, and a timing module is electrically connected to the lifting drive device 6 through a control module.

[0014] The water bath mechanism can adopt a commonly used water bath pot. Based on the original water bath pot, this solution adds a timing scooping device on the pot mouth. Before starting, a water bath time is preset for the timing module. The sample bottle containing the sample test solution is placed on the sample rack in advance, and the sample rack is installed and fixed relative to the support structure. The support structure is lowered to immerse the sample bottle body in the water bath pot. After immersion, the timing module starts timing. When the preset time is reached, the support structure rises to fish out the sample bottle and let it stand, thereby avoiding the scrapping of the sample due to forgetting to bathe for too long in water.

[0015] The mounting frame 1 includes a support body 11 placed on the end surface of the water bath mechanism 2. The middle part of the support body 11 is hollowed out to form a movable interval for the lifting and lowering of the support structure 3. A plurality of lifting and sliding carriers 12 are fixed above the support body 11, and each lifting and sliding carrier 12 is provided with a corresponding lifting and lowering support structure 3.

[0016] The lifting and sliding carrier uses multiple vertically arranged guide rails, and the multiple guide rails are arranged around the support structure 3, which can make the lifting and lowering process of the support structure more stable. Arranging multiple lifting and sliding carriers can simultaneously carry out water bathing of multiple samples with the same temperature requirements, and the lifting and lowering support structures on each carrier are connected to a separate timing module, so that they can be taken out after the corresponding water bath time.

[0017] The support structure 3 includes a lifting platform 31 that is slidably matched with the lifting and sliding carrier 12. Two clamping units 32 are relatively slidably arranged on the support surface of the lifting platform 31. The two clamping units 32 are connected by an adjustment structure 33. The two clamping units 32 are relatively clamped on both sides of the sample rack 4.

[0018] The sample rack placed on the lifting platform surface is clamped and fixed by two clamping units with adjustable spacing to prevent the sample rack from moving around during the lifting process, thereby preventing the sample from tipping over and ensuring the stability of the sample during the lifting process. The adjustment structure can adopt a bolt structure, and threaded holes that match the bolts are opened at corresponding positions on the two clamping bodies, and the threads of the two at the matching positions on the same screw rod have opposite rotation directions. It can be adaptively adjusted according to the sample racks of different sizes placed, improving its versatility.

[0019] A heat insulation board 13 is provided between the support body 11 and the end surface of the bath mechanism 2 for transverse sliding movement. After the water bath is completed, the sample rack can be removed from the water bath pot by the heat insulation board to isolate the hot air in the pot from baking, so that the sample in the sample bottle enters a static cooling state.

[0020] The upper and lower limit positions of the lifting and sliding carrier 12 are respectively provided with sensing modules 9 for sensing the limit position status of the lifting platform 31. Both of the sensing modules 9 are electrically connected to the timing module through the control module. The heat insulation board 13 is connected to the opening and closing drive device 8 that drives it to slide laterally, and the sensing module 9 on the upper side is electrically connected to the opening and closing drive device 8 through the control module. The timing accuracy can be guaranteed. When the lifting platform is lowered into place, the limit position sensing module at the lower end is touched, thereby controlling the timing module to start timing. When the preset time is reached, the lifting platform is lifted. When the lifting platform rises to the limit position, the limit position sensing module at the upper end is touched, thereby controlling the heat insulation board to slide and block the water bath and the sample rack. At the same time, the timing can be turned on again and the time can be displayed, and the static time of the sample can be accurately timed.

[0021] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
